Subject: [PATCH 0001/5214] openrisc: mm: Fix section mismatch between map_page
 and __set_fixmap

This warning was reported by the kernel test robot:

  WARNING: modpost: vmlinux: section mismatch in reference: __set_fixmap+0x84 (section: .text.unlikely) -> map_page.isra.0 (section: .init.text)

With commit 4735037b5d9b ("openrisc: Add text patching API support") the
__set_fixmap function was moved out of the .init.text section.
However, the map_page helper that it uses was not moved.  This was not
noticed on gcc 15.1.0 where map_page gets inlined unlike lkp@intel.com
which uses gcc 10.5.0.

Fix this by also moving the map_page helper function out of the init
section.

Subject: [PATCH 0003/5214] gfs2: fix quota init duplicate scan

gfs2_quota_init() checks for duplicate quota_change IDs while holding
qd_lock and the quota hash bucket bitlock. That path used
gfs2_qd_search_bucket(), which takes a lockref reference via
lockref_get_not_dead().

On PREEMPT_RT this may sleep, which is not allowed under the bucket
bitlock, triggering "sleeping function called from invalid context".

Use a no-ref bucket lookup in this path, then continue duplicate
handling without taking a lockref there.

Refactor gfs2_qd_search_bucket() to build on top of the no-ref helper
so lookup traversal stays in one place.

This patch fixes a bug reported by syzbot.

Move qc++ from the loop body into the for-loop increment
expression in gfs2_quota_init().

This keeps iterator progression explicit and avoids mixing pointer

Subject: [PATCH 0005/5214] Input: stmfts - fix the MODULE_LICENSE() string

Replace the bogus "GPL v2" with "GPL" as MODULE_LICNSE() string. The
value does not declare the module's exact license, but only lets the
module loader test whether the module is Free Software or not.

See commit bf7fbeeae6db ("module: Cure the MODULE_LICENSE "GPL" vs.
"GPL v2" bogosity") in the details of the issue. The fix is to use
"GPL" for all modules under any variant of the GPL.

Subject: [PATCH 0014/5214] thunderbolt: debugfs: Don't stop reading SB
 registers if just one fails

The GEN4 TxFFE register is not part of the USB4 v1.0 specification, so
understandably some pre-USB4v2 retimers (like the Parade PS8830) don't
seem to implement it.

The immediate idea to counter this would be to introduce a version
check for that specific register, but on a second thought, the current
flow only returns a quiet -EIO if there's any failures, without hinting
at what the actual problem is.

To take care of both of these issues, simply print an error line for
each SB register read that fails and go on with attempting to read the
others.

Note that this is not quite in-spec behavior ("The SB Register Space
registers shall have the structure and fields described in Table 4-17.
Registers not listed in Table 4-20 are undefined and shall not be
used."), but it's the easiest fix that shouldn't have real-world bad
side effects.

Check return value of iio_compute_scan_bytes() as it can return an
error.

The result is moved to an output parameter while we are touching this
as we will need to add a second output parameter in a later change.

The return type of iio_buffer_update_bytes_per_datum() also had to be
changed to propagate the error.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cache the offset (in bytes) for the timestamp element in a scan buffer.
This will be used later to ensure proper alignment of the timestamp
element in the scan buffer.

The new field could not be placed in struct iio_dev_opaque because we
will need to access it in a static inline function later, so we make it
__private instead. It is only intended to be used by core IIO code.

 two
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use roundup_pow_of_two() in the calculation of iio_storage_bytes_for_si()
when scan_type->repeat > 1 to ensure that the size is a power of two.
storagebits is always going to be a power of two bytes, so we only need
to apply this to the repeat factor. The storage size is also used for
alignment, and we want to ensure that all alignments are a power of two.

The only repeat in use in the kernel currently is for quaternions, which
have a repeat of 4, so this does not change the result for existing
users.

Subject: [PATCH 0018/5214] iio: buffer: fix timestamp alignment when
 quaternion in scan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix timestamp alignment when a scan buffer contains an element larger
than sizeof(int64_t). Currently s32 quaternions are the only such
element, and the one driver that has this (hid-sensor-rotation) has a
workaround in place already so this change does not affect it.

Previously, we assumed that the timestamp would always be 8-byte aligned
relative to the end of the scan buffer, but in the case of a scan buffer
a 16-byte quaternion vector, scan_bytes == 32, but the timestamp needs
to be placed at offset 16, not 24.

ts_offset is now a value in bytes so we have to change how the array
access is done.

Move the scan buf.chans array into a union along with a struct that
gives the layout of the buffer with all channels enabled.

Although not technically required in this case, if there had been a
different number of items before the quaternion, there could have been
a subtle bug with the special alignment needed for the quaternion
channel data and the array would have been too small.

Subject: [PATCH 0022/5214] iio: imu: st_lsm6dsx: Fix check for invalid samples
 from FIFO

The DRDY_MASK feature implemented in sensor chips marks gyroscope and
accelerometer invalid samples (i.e. samples that have been acquired during
the settling time of sensor filters) with the special values 0x7FFFh,
0x7FFE, and 0x7FFD.
The driver checks FIFO samples against these special values in order to
discard invalid samples; however, it does the check regardless of the type
of samples being processed, whereas this feature is specific to gyroscope
and accelerometer data. This could cause valid samples to be discarded.

Fix the above check so that it takes into account the type of samples being
processed. To avoid casting to __le16 * when checking sample values, clean
up the type representation for data read from the FIFO.

Subject: [PATCH 0023/5214] iio: Replace 'sign' field with union in struct
 iio_scan_type

This field is used to differentiate between signed and unsigned integers.
A following commit will extend its use in order to add support for non-
integer scan elements; therefore, replace it with a union that contains a
more generic 'format' field. This union will be dropped when all drivers
are changed to use the format field.
Opportunistically replace character literals with symbolic constants that
represent the set of allowed values for the format field.

In the data storage description of a scan element, the first character
after the colon can have the values 's' and 'u' to specify signed and
unsigned integers, respectively.
Add 'f' as an allowed value to specify floating-point numbers formatted
according to the IEEE 754 standard.

+		- the rotation angle is within the [-pi, pi] range, i.e. the w
+		  component (which represents the amount of rotation) is non-negative
+
+		These constraints allow the w value to be calculated from the other

From cd4e1141bff8b86c75c425acb84eca453e936a9d Mon Sep 17 00:00:00 2001

Subject: [PATCH 0027/5214] iio: imu: st_lsm6dsx: Add support for rotation
 sensor

Some IMU chips in the LSM6DSX family have sensor fusion features that
combine data from the accelerometer and gyroscope. One of these features
generates rotation vector data and makes it available in the hardware
FIFO as a quaternion (more specifically, the X, Y and Z components of the
quaternion vector, expressed as 16-bit half-precision floating-point
numbers).

Add support for a new sensor instance that allows receiving sensor fusion
data, by defining a new struct st_lsm6dsx_fusion_settings (which contains
chip-specific details for the sensor fusion functionality), and adding this
struct as a new field in struct st_lsm6dsx_settings. In st_lsm6dsx_core.c,
populate this new struct for the LSM6DSV and LSM6DSV16X chips, and add the
logic to initialize an additional IIO device if this struct is populated
for the hardware type being probed.
Note: a new IIO device is being defined (as opposed to adding channels to
an existing device) because the rate at which sensor fusion data is
generated may not match the data rate from any of the existing devices.

Tested on LSM6DSV16X.

Subject: [PATCH 0028/5214] iio: adc: ltc2309: add read delay for ltc2305
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The LTC2305 requires a minimum 1.6μs delay between the I2C write
operation (channel selection) and the subsequent read operation to
allow the chip to process the command and prepare the result. While
not explicitly documented in the datasheet, this timing requirement
was identified by the hardware designer as necessary for reliable
operation.

Add a read_delay_us field to both the ltc2309_chip_info and ltc2309
device structures to support chip-specific timing requirements. Use
fsleep() to implement the delay when non-zero, with LTC2305 set to
2μs (1.6μs requirement rounded up). LTC2309 does not require
additional delay beyond inherent I2C bus timing.

This extends the existing LTC2305 support added in
(commit 8625d418d24b ("iio: adc: ltc2309: add support for ltc2305"))
with the missing inter-transaction delay.

Subject: [PATCH 0029/5214] iio: adc: ltc2309: Optimize chip_info structure
 layout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Improve the ltc2309_chip_info structure with better type safety and
memory efficiency:

- Add __counted_by_ptr() annotation to the channels pointer, linking
  it to num_channels for improved bounds checking and kernel hardening
- Reorder structure fields to minimize padding:
  * Place read_delay_us before num_channels
  * This reduces struct size and eliminates internal gaps
- Reorder field initialization to match the structure definition order

The __counted_by_ptr() attribute enables compile-time and runtime
verification that array accesses to channels[] stay within the bounds
specified by num_channels, improving memory safety.

Subject: [PATCH 0047/5214] iio: adc: ti-ads8688: use read_avail for available
 attributes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Convert the in_voltage_scale_available and in_voltage_offset_available
attributes from legacy IIO_DEVICE_ATTR with custom show functions to the
IIO framework's read_avail callback. This uses the framework's built-in
support for _available attributes, removing the need for manual sysfs
formatting.

Precompute the available scale values at probe time since they depend on
the reference voltage which does not change after initialization.

 header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove kernel.h proxy header and add replacement headers (array_size.h,
dev_printk.h, kstrtox.h, mod_devicetable.h, mutex, types.h, asm/byteorder.h) to
maintain atomicity. Moved asm/div64.h header below generic <linux/*>
headers. Additionally, add bitops.h for BIT_ULL() macro.

Audited using the include-what-you-use tool.

Subject: [PATCH 0063/5214] iio: dac: mcp4821: add configurable gain support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for configuring the DAC gain using the GA bit

The MCP4821 supports two gain settings:
- 1x gain → 2.048V full-scale
- 2x gain → 4.096V full-scale

Scale write support is added in the IIO interface. Only scale
values advertised via the scale_available attribute are accepted,
ensuring consistency between the configured gain and exposed
scale values.

Subject: [PATCH 0064/5214] iio: light: vcnl4000: validate device by prod ID
 instead of table ID

Add a new field for vcnl4000_chip_spec and check if we have the right
device by that instead of the index from enum table. This leaves the
enum table being used only for picking the right vcnl4000_chip_spec,
allowing us to drop it later on.

Subject: [PATCH 0072/5214] iio: adc: ad799x: use a static buffer for scan data

Currently, rx_buf is dynamically allocated using kmalloc() every time
ad799x_update_scan_mode() is called. This can lead to memory leaks if
the scan mask is updated multiple times.

Drop the dynamic allocation and replace it with a static buffer at the
end of the state structure using IIO_DECLARE_BUFFER_WITH_TS().
This eliminates the allocation overhead, prevents leaks, and removes
the need for manual kfree() on driver removal.

Subject: [PATCH 0074/5214] iio: adc: ad799x: convert to fully managed
 resources and drop remove()

Convert the driver's remaining manual resource management to use the
devm_ infrastructure, allowing for the complete removal of the
ad799x_remove() function and the simplification of the probe error paths.

Specifically:
- Initialize the mutex using devm_mutex_init() and move it to the top
  of probe() (before IRQ registration) to prevent a race condition where
  an interrupt could attempt to take an uninitialized lock.
- Use devm_add_action_or_reset() to ensure that the VCC and VREF
  regulators are disabled safely and in the correct order during driver
  teardown or probe failure.
- Refactor the optional VREF error handling path for better readability.
- Convert iio_triggered_buffer_setup() and iio_device_register() to
  their devm_ variants.

Because all resources are now managed by the devm core, the unwinding
order is guaranteed to follow the reverse order of allocation. All manual
error handling goto labels in ad799x_probe() have been removed.

Subject: [PATCH 0075/5214] iio: adc: ti-ads7950: use spi_optimize_message()

Use spi_optimize_message() to reduce CPU usage during buffered reads.

On hardware with support for SPI_CS_WORD, this reduced the CPU usage
of the threaded interrupt by about 5%. On hardware without support, this
should reduce CPU usage even more since it won't have to split the SPI
transfers each time the interrupt handler is called.

The .update_scan_mode() callback hand to be moved to the buffer preenable
callback since the SPI transfer mode can't be changed after
spi_optimize_message() has been called. (The buffer postenable callback
can't be used because it happens after the trigger is enabled, so the
SPI message needs to be optimized before that.)

The indent of the pointer to ti_ads7950_read_raw() in the assignment
is changed since there is no longer anything else in the struct to
align with since removal of use of the pointer to
ti_ads7950_update_scan_mode().

resulting !-test is semantically identical.

 selection

Both ad4170_gpio_direction_input() and
ad4170_gpio_direction_output() duplicate the same switch
statement to map a GPIO offset to its corresponding mask.

Replace the switch with a static lookup table, simplifying the code
and avoiding duplication. This also makes future extensions easier.

No functional change intended.

Use 'u32' instead of bare 'unsigned' to resolve checkpatch.pl warnings
and correct type use as defined in the struct hid_sensor_hub_callbacks.

No functional change.

Subject: [PATCH 0093/5214] iio: adc: ad4130: add new supported parts

Add support for AD4129-4/8, AD4130-4, and AD4131-4/8 variants.

The AD4129 series supports the same FIFO interface as the AD4130 but with
reduced resolution (16-bit). The AD4131 series lacks FIFO support, so
triggered buffer functionality is introduced.

The 4-channel variants feature fewer analog inputs, GPIOs, and sparse pin
mappings for VBIAS, analog inputs, and excitation currents. The driver now
handles these differences with chip-specific configurations, including pin
mappings and GPIO counts.

Subject: [PATCH 0094/5214] iio: adc: qcom: Unify user-visible "Qualcomm" name

Various names for Qualcomm as a company are used in user-visible config
options: QCOM, Qualcomm and Qualcomm Technologies.  Switch to unified
"Qualcomm" so it will be easier for users to identify the options when
for example running menuconfig.

Extract the upper and lower bytes of chan->address into named local
variables devaddr and ch across ad7280_read_raw(),
ad7280_show_balance_timer() and ad7280_store_balance_timer() to improve
readability and avoid inline bit manipulation in function calls.

Subject: [PATCH 0096/5214] iio: adc: ad7280a: use cleanup helpers guard() and
 scoped_guard() for mutex locking

Replace open-coded mutex_lock/unlock pairs with the cleanup-based
guard() and scoped_guard() helpers in ad7280a_write_thresh(),
ad7280_show_balance_timer(), ad7280_store_balance_sw(),
ad7280_store_balance_timer() and ad7280_read_raw().

This removes the need for the err_unlock label and explicit
mutex_unlock() calls, as the lock is now automatically released
when the function returns or the guarded scope exits, regardless
of the exit path.

Subject: [PATCH 0100/5214] iio: proximity: srf08: Replace sprintf() with
 sysfs_emit()

Replace sprintf() function calls with sysfs_emit() and
sysfs_emit_at(). While the current code is fine, sysfs_emit() is
preferred over sprintf(), and will help modernize the driver.

Subject: [PATCH 0103/5214] misc: Remove old APDS990x driver

The APDS990x driver in misc lacks DeviceTree support, and no mainline
pre-DT board files configured this device using apds990x_platform_data.

This driver belongs to a legacy group of ambient light sensor drivers in
drivers/misc/ that predates the migration to DT and the standard IIO ABI.

Since the Avago APDS9900/9901 ALS/Proximity sensor is now supported by
the tsl2772 IIO driver and there are no active users in the kernel tree,
remove this old implementation.

-Description
------------
-
-APDS990x is a combined ambient light and proximity sensor. ALS and proximity
-functionality are highly connected. ALS measurement path must be running
-while the proximity functionality is enabled.
-
-ALS produces raw measurement values for two channels: Clear channel
-(infrared + visible light) and IR only. However, threshold comparisons happen
-using clear channel only. Lux value and the threshold level on the HW
-might vary quite much depending the spectrum of the light source.
-
-Driver makes necessary conversions to both directions so that user handles
-only lux values. Lux value is calculated using information from the both
-channels. HW threshold level is calculated from the given lux value to match
-with current type of the lightning. Sometimes inaccuracy of the estimations
-lead to false interrupt, but that doesn't harm.
-
-ALS contains 4 different gain steps. Driver automatically
-selects suitable gain step. After each measurement, reliability of the results
-is estimated and new measurement is triggered if necessary.
-
-Platform data can provide tuned values to the conversion formulas if
-values are known. Otherwise plain sensor default values are used.
-
-Proximity side is little bit simpler. There is no need for complex conversions.
-It produces directly usable values.
-
-Driver controls chip operational state using pm_runtime framework.
-Voltage regulators are controlled based on chip operational state.
-
-SYSFS
------
-
-
-chip_id
-	RO - shows detected chip type and version
-
-power_state
-	RW - enable / disable chip. Uses counting logic
-
-	     1 enables the chip
-	     0 disables the chip
-lux0_input
-	RO - measured lux value
-
-	     sysfs_notify called when threshold interrupt occurs
-
-lux0_sensor_range
-	RO - lux0_input max value.
-
-	     Actually never reaches since sensor tends
-	     to saturate much before that. Real max value varies depending
-	     on the light spectrum etc.
-
-lux0_rate
-	RW - measurement rate in Hz
-
-lux0_rate_avail
-	RO - supported measurement rates
-
-lux0_calibscale
-	RW - calibration value.
-
-	     Set to neutral value by default.
-	     Output results are multiplied with calibscale / calibscale_default
-	     value.
-
-lux0_calibscale_default
-	RO - neutral calibration value
-
-lux0_thresh_above_value
-	RW - HI level threshold value.
-
-	     All results above the value
-	     trigs an interrupt. 65535 (i.e. sensor_range) disables the above
-	     interrupt.
-
-lux0_thresh_below_value
-	RW - LO level threshold value.
-
-	     All results below the value
-	     trigs an interrupt. 0 disables the below interrupt.
-
-prox0_raw
-	RO - measured proximity value
-
-	     sysfs_notify called when threshold interrupt occurs
-
-prox0_sensor_range
-	RO - prox0_raw max value (1023)
-
-prox0_raw_en
-	RW - enable / disable proximity - uses counting logic
-
-	     - 1 enables the proximity
-	     - 0 disables the proximity
-
-prox0_reporting_mode
-	RW - trigger / periodic.
-
-	     In "trigger" mode the driver tells two possible
-	     values: 0 or prox0_sensor_range value. 0 means no proximity,
-	     1023 means proximity. This causes minimal number of interrupts.
-	     In "periodic" mode the driver reports all values above
-	     prox0_thresh_above. This causes more interrupts, but it can give
-	     _rough_ estimate about the distance.
-
-prox0_reporting_mode_avail
-	RO - accepted values to prox0_reporting_mode (trigger, periodic)
-
-prox0_thresh_above_value
-	RW - threshold level which trigs proximity events.

Subject: [PATCH 0105/5214] pinctrl: renesas: rzg2l: Handle RZ/V2H(P) IOLH
 configuration in PM cache

Include PIN_CFG_IOLH_RZV2H in the IOLH capability checks when saving
and restoring pin configuration registers.

On RZ/V2H(P), RZ/V2N, and RZ/G3E, the IOLH configuration is defined by
the PIN_CFG_IOLH_RZV2H capability.  The previous implementation did not
account for this, causing the IOLH registers to be skipped during PM
save/restore.

Drop the unwanted check in rzg3s_cpg_pll_clk_recalc_rate() as the
function is SoC-specific.

Subject: [PATCH 0109/5214] clk: renesas: rzg2l: Add support for enabling PLLs

Add support for enabling PLL clocks in the RZ/G3L CPG driver to turn off
some PLLs, if they are not in use (e.g. PLL6, PLL7).

Introduce .is_enabled() and .enable() callbacks to handle PLL state
transitions.  With the .enable() callback, the PLL will be turned ON
only when the PLL consumer device is enabled; otherwise, it will remain
off.  Define new macros for PLL standby and monitor registers to
facilitate this process.

Subject: [PATCH 0111/5214] clk: renesas: r9a08g046: Add GBETH clocks and
 resets

Add clock and reset entries for the Gigabit Ethernet Interfaces (GBETH
0-1) IPs found on the RZ/G3L SoC.  This includes various dividers and
mux clocks needed by these two GBETH IPs.  Also add the tx, tx-180, rx,
rx-180, rmii, rmii-tx and rmii-rx clocks to the r9a08g046_no_pm_mod_clk
table to avoid enabling both normal and RMII clocks by the PM framework.

Remove the !hdm_ch check. hdm_ch is derived from dev->hch + ch_idx
(pointer arithmetic on a struct member), so it can never be NULL.
Keep only the !hdm_ch->is_initialized check.

Subject: [PATCH 0123/5214] staging: most: video: remove redundant cleanup in
 comp_exit()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

most_deregister_component() already calls disconnect_channel() for
every linked channel via bus_for_each_dev() in core.c, which invokes
comp_disconnect_channel() to remove each entry from the video_devices
list and tear down the V4L2 device.

The manual cleanup loop in comp_exit() duplicates this work and is
guarded by a stale comment claiming that "mostcore currently doesn't
call disconnect_channel() for linked channels" — but the core has
since been fixed to do exactly that.

Remove the redundant manual cleanup loop, the outdated comment, and
the BUG_ON() assertion that checked for a condition that can no longer
occur.

Subject: [PATCH 0124/5214] staging: sm750fb: constify fix_id array

Add the missing 'const' qualifier to the static fix_id array to ensure
the pointer array itself is immutable.

Originally:
    static const char *fix_id[2];
The strings are constant, but the pointer array itself is writable.

With the change:
    static const char * const fix_id[2];
Both the strings and the pointer array are immutable, allowing the
compiler to treat the object as read-only.

Verified by inspecting the generated object file with 'nm':

    00000000000002b8 0000000000000010 r fix_id.3

The 'r' flag indicates the symbol is placed in a read-only section.

This does not change runtime behavior as fix_id is never modified.

Subject: [PATCH 0126/5214] staging: sm750fb: fix off-by-one in
 lynxfb_ops_setcolreg
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The bounds check used regno > 256 instead of regno >= 256,
allowing regno == 256. Valid indices are 0–255, resulting
in an out-of-bounds write.

Also remove the regno < 256 check in the truecolor path,
as it is always true with the corrected guard.

The functions sm750_enable_i2c() and sm750_hw_cursor_set_data2() are
defined and declared but never used. Following the driver's TODO list
to remove unused code, this patch deletes these dead functions.

Verified by compilation and cppcheck.

IsFrameTypeCtrl() returned true else false, with a single return
statement returning true only if GetFrameType(pframe) == WIFI_CTRL_TYPE

Replace the existing rtw_read8() and do-while loop mechanism with

which is a standard Linux macro, ensuring polling REG_HMETFR efficiently.

The code previously checked (Rate >= MGN_MCS0 && Rate <= MGN_MCS7)
condition twice - once for the (BandWidth == CHANNEL_WIDTH_20) check and
once for the (BandWidth == CHANNEL_WIDTH_40) check. Fix if statement
formatting to move that if check as an outer if check to improve code
formatting.

The struct rtw_regulatory is never used in the rtl8723bs driver.
Functions taking it as a parameter are always passed NULL and
perform no logic with it. Remove the dead code and the struct.

Subject: [PATCH 0172/5214] staging: rtl8723bs: clean up memcpy() in
 rtw_check_bcn_info

Move the ssid memcpy() inside the ie null-check to avoid calling it
with a NULL-derived pointer (p + 2) when the ie is missing.

While the kernel handles 0-length memcpy() safely as a no-op, keeping
the call outside the check is confusing and poor practice. This
change improves code readability.

Subject: [PATCH 0173/5214] staging: rtl8723bs: remove dump_chip_info()
 function

The dump_chip_info() function formats chip version information into a
local 128-byte buffer using the scnprintf(). This buffer was previously
passed to the DBG_871X macro.
Commit 968b15adb0ea ("staging: rtl8723bs: remove all DBG_871X logs")
removed the macro, leaving the buffer formatted but never used or output
anywhere.

dump_chip_info() is now useless, so remove it and its call from
ReadChipVersion8723B().

 pointers

The %pe format specifier resolves error pointers to their symbolic
representation. Previously %ld with PTR_ERR() was being used, %pe is a
better alternative.

Fixes the following coccinelle warnings reported by coccicheck:
WARNING: Consider using %pe to print PTR_ERR()

Testing: I do not own the hardware, therefore I could not perform
hardware testing. Compile tested only.

Subject: [PATCH 0177/5214] staging: rtl8723bs: remove wrapper
 rtw_hal_read_chip_version()

Remove rtw_hal_read_chip_version() function, as it's just a wrapper
that calls rtl8723b_read_chip_version() directly. Replace all its calls
to the rtl8723b_read_chip_version(). This will remove an extra level of
abstraction and simplify the code.

Subject: [PATCH 0184/5214] staging: rtl8723bs: remove unused offset in phase 2
 _BlockWrite()

Commit c1314fe4d28f ("staging: rtl8723bs: remove all RT_TRACE logs
in hal/ and os_dep/") removed the unnecessary RT_TRACE logs in hal/
and os_dep/ files, but left the variable "offset" in the Phase 2
_BlockWrite() function unused, so delete it.

This is reported by Coverity Scan with CID 1408950 as UNUSED_VALUE.

Subject: [PATCH 0191/5214] usb: cdnsp: add support for eUSB2v2 port

The Cadence CDNSP controller optionally supports eUSB2 (embedded USB2)
port. While this port type operates logically like high-speed USB 2.0,
it utilizes a different physical layer signaling.

This patch:
- Extends the port detection logic to recognize the eUSB2 protocol.
- Tracks the eUSB2 port offset in the cdnsp_device structure.
- Ensures that eUSB2 ports are correctly handled during Link State
  transitions, specifically forcing L0 when LPM is capable, similar
  to standard USB 2.0 ports.

Subject: [PATCH 0192/5214] usb: gadget: udc: skip pullup() if already
 connected

The device controller may update vbus status via usb_udc_vbus_handler(),
which tries to connect the gadget even though gadget_bind_driver() has
already called usb_udc_connect_control_locked(). This causes pullup() to
be called twice. Avoid this by checking if gadget->connected is true.

This also set gadget->connected as false in usb_gadget_activate() if it
became connected while it was being deactivated. Otherwise,
usb_gadget_connect_locked will return early and pullup() won't be called.

Subject: [PATCH 0193/5214] dt-bindings: usb: cdns,usb3: document USBSSP
 controller support

Update the Cadence USBSS DRD binding to document that it also covers
the USBSSP (SuperSpeed Plus, USB 3.1 gen2x1) controller. Both USBSS
and USBSSP share the same DRD/OTG register interface, so the driver
auto-detects the controller version at runtime: no additional
compatible string is needed.

Changes to the binding:
- Update title and add description
- maximum-speed: add super-speed-plus

Subject: [PATCH 0194/5214] usb: cdns3: Add USBSSP platform driver support

Expose Cadence USBSSP through the same platform path as USBSS, trim
Kconfig and Makefile: one core loadable object plus separate glue .ko
files.

Single cdns.ko bundles core, DRD, the generic "cdns,usb3" platform
driver in cdns3-plat.c, optional host.o, and optional gadget objects.
Use CONFIG_USB_CDNS3_GADGET as a bool to compile gadget support into
that module. Remove duplicate MODULE_* declarations from cdns3-plat.c
now that it links into the same module.

Kconfig: the generic platform driver is selected via CONFIG_USB_CDNS3.
Move CONFIG_USB_CDNSP_PCI beside CONFIG_USB_CDNS3_PCI_WRAP under
"Platform glue driver support". SoC glue entries (TI, i.MX, StarFive)
depend only on CONFIG_USB_CDNS3.

Tighten CONFIG_USB_CDNS_SUPPORT dependencies so the umbrella follows
host or gadget when either is built as a module. Match host and gadget
bools to the cdns.ko tristate with USB=USB_CDNS3 and USB_GADGET=USB_CDNS3
instead of comparing against USB_CDNS_SUPPORT.

Link host.o when CONFIG_USB_CDNS3_HOST is enabled and use that symbol in
host-export.h, removing the redundant CONFIG_USB_CDNS_HOST indirection.

Export cdns_core_init_role and reorganize the function cdns_init, and
controller version could be gotten before the gadget init function is
decided per controller.

Keep host_init / gadget_init callbacks in struct cdns, so core.c does
not need direct linkage to host or gadget objects. Refactor cdnsp-pci.c
into a thin PCI-to-platform wrapper.

drivers/usb/Makefile: descend into drivers/usb/cdns3/ only when
CONFIG_USB_CDNS_SUPPORT is enabled.

Subject: [PATCH 0195/5214] ima: Fix sigv3 signature handling for
 EVM_IMA_XATTR_DIGSIG

ima_get_hash_algo() only recognizes version 2 signatures when the xattr
type is EVM_IMA_XATTR_DIGSIG. Since sigv3 signatures also use
EVM_IMA_XATTR_DIGSIG as the xattr type, version 3 must be accepted as
well to correctly determine the hash algorithm.

Additionally, ima_validate_rule() does not include IMA_SIGV3_REQUIRED in
the allowed flags bitmask for MODULE_CHECK, KEXEC_KERNEL_CHECK, and
KEXEC_INITRAMFS_CHECK hook functions. As a result, policy rules with
"appraise_type=sigv3" are rejected for these functions.

Add version 3 to the accepted versions in ima_get_hash_algo() for
EVM_IMA_XATTR_DIGSIG, and add IMA_SIGV3_REQUIRED to the allowed flags
for MODULE_CHECK, KEXEC_KERNEL_CHECK, and KEXEC_INITRAMFS_CHECK in
ima_validate_rule().

Subject: [PATCH 0198/5214] clk: rockchip: allow grf_type_sys lookup in
 aux_grf_table

Remove the grf_type_sys exclusion from the auxiliary GRF table lookup
in rockchip_clk_register_branches(). Previously, branches with
grf_type_sys always used ctx->grf directly, bypassing the aux_grf_table.

This is a problem on SoCs like RK3588 where ctx->grf points to the
PHP_GRF (set via the CRU's rockchip,grf phandle), but GATE_GRF clock
entries need to access the SYS_GRF instead.

With this change, grf_type_sys branches first check the aux_grf_table,
and fall back to ctx->grf if no entry is found. This is backwards
compatible: on SoCs that do not register grf_type_sys in the
aux_grf_table, the behavior is unchanged.

Subject: [PATCH 0201/5214] clk: rockchip: rk3588: add GATE_GRF clocks for I2S
 MCLK output to IO

The I2S MCLK outputs on RK3588 are gated by bits in the SYS_GRF
register SOC_CON6 (offset 0x318). These gates control whether the
internal CRU MCLK signals reach the external IO pins connected to
audio codecs.

The kernel should explicitly manage these gates so that audio
functionality does not depend on bootloader register state. This is
analogous to what was done for RK3576 SAI MCLK outputs [1].

Register the SYS_GRF as an auxiliary GRF with grf_type_sys using
rockchip_clk_add_grf(), and add GATE_GRF entries for all four I2S
MCLK output gates:

  - I2S0_8CH_MCLKOUT_TO_IO (bit 0)
  - I2S1_8CH_MCLKOUT_TO_IO (bit 1)
  - I2S2_2CH_MCLKOUT_TO_IO (bit 2)
  - I2S3_2CH_MCLKOUT_TO_IO (bit 7)

Board DTS files that need MCLK on an IO pin can reference these
clocks, e.g.:

    clocks = <&cru I2S0_8CH_MCLKOUT_TO_IO>;

Tested on the Youyeetoo YY3588 (RK3588) with an ES8388 codec on I2S0.

Replace deprecated simple_strtoul with kstrtouint for better error
handling and type safety. The kstrtouint function provides stricter
validation, automatically rejecting inputs like "123abc" that
simple_strtoul would partially accept.

Using kstrtouint avoids unsigned long to int conversion and is more
appropriate for MTD device indices which are non-negative integers.

Subject: [PATCH 0205/5214] PCI: Stop setting cached power state to 'unknown'
 on unbind

When a PCI device is unbound from its driver, pci_device_remove() sets the
cached power state in pci_dev->current_state to PCI_UNKNOWN.  This was
introduced by commit 2449e06a5696 ("PCI: reset pci device state to unknown
state for resume") to invalidate the cached power state in case the system
is subsequently put to sleep.

For bound devices, the cached power state is set to PCI_UNKNOWN in
pci_pm_suspend_noirq(), immediately before entering system sleep.

Extend to unbound devices for consistency.

This obviates the need to change the cached power state on unbind, so stop
doing so.

Subject: [PATCH 0206/5214] PCI: Skip Resizable BAR restore on read error

pci_restore_rebar_state() uses the Resizable BAR Control register to decide
how many BARs to restore (nbars) and which BAR each iteration addresses
(bar_idx).

When a device does not respond, config reads typically return
PCI_ERROR_RESPONSE (~0).  Both fields are 3 bits wide, so nbars and bar_idx
both evaluate to 7, past the spec's valid ranges for both fields.
pci_resource_n() then returns an unrelated resource slot, whose size is
used to derive a nonsensical value written back to the Resizable BAR
Control register.

Bail out if any Resizable BAR Control read returns PCI_ERROR_RESPONSE. No
further BARs are touched, which is safe because a config read that returns
PCI_ERROR_RESPONSE indicates the device is unreachable and restoration is
pointless.

Subject: [PATCH 0207/5214] PCI/IOV: Skip VF Resizable BAR restore on read
 error

sriov_restore_vf_rebar_state() uses the VF Resizable BAR Control register
to decide how many VF BARs to restore (nbars) and which VF BAR each
iteration addresses (bar_idx). bar_idx indexes into dev->sriov->barsz[],
which has only PCI_SRIOV_NUM_BARS (6) entries.

When a device does not respond, config reads typically return
PCI_ERROR_RESPONSE (~0).  Both fields are 3 bits wide, so nbars and bar_idx
both evaluate to 7. The barsz[] access then goes out of bounds.  UBSAN
reports this as:

  UBSAN: array-index-out-of-bounds in drivers/pci/iov.c:948:51 index 7 is out of range for type 'resource_size_t [6]'

Observed on an NVIDIA RTX PRO 1000 GPU (GB207GLM) that stopped responding
during a failed GC6 power state exit. The subsequent pci_restore_state()
invoked sriov_restore_vf_rebar_state() while config reads returned
0xffffffff, triggering the splat.

Bail out if any VF Resizable BAR Control read returns PCI_ERROR_RESPONSE.
No further VF BARs are touched, which is safe because a config read that
returns PCI_ERROR_RESPONSE indicates the device is unreachable and
restoration is pointless. This mirrors the guard in
pci_restore_rebar_state().

pci_pwrctrl_is_required() detects whether a device needs PCI pwrctrl
support. It is currently used in pci_pwrctrl_create_device(), but not in
pci_pwrctrl_power_{on/off}_device() APIs. This leads to pwrctrl core trying
to power on/off incompatible devices like USB hub downstream ports defined
in DT.

Add this check to prevent pwrctrl core from poking at wrong devices.

Subject: [PATCH 0210/5214] PCI/P2PDMA: Avoid returning a provider for
 non_mappable_bars

Extend the checks in pcim_p2pdma_init() and pcim_p2pdma_provider() to
exclude functions that have pdev->non_mappable_bars set.

Consumers such as VFIO were previously able to map these for access by the
CPU or P2P.  Update the comment on non_mappable_bars to show it refers to
any access, not just userspace CPU access.

Fixes: 372d6d1b8ae3c ("PCI/P2PDMA: Refactor to separate core P2P functionality from memory allocation")

Subject: [PATCH 0211/5214] PCI: Remove MPS/MRRS Kconfig settings
 (CONFIG_PCIE_BUS_*)

Revert b0e85c3c8554 ("PCI: Add Kconfig options for MPS/MRRS strategy"),
which allowed build-time selection of the "off", "default", "safe",
"performance", or "peer2peer" strategies for MPS and MRRS configuration.
These strategies can be selected at boot-time using the
"pci=pcie_bus_tune_*" kernel parameters.

Per the discussion mentioned below, these Kconfig options were added to
work around a hardware defect in a WiFi device used in a cable modem.  The
defect occurred only when the device was configured with MPS=128, and
Kconfig was a way to avoid that setting.  It was easier for the modem
vendor to use Kconfig and update the kernel image than to change the kernel
parameters.

Neither Kconfig nor kernel parameters are a complete solution because the
broken WiFi device may be used in other systems where it may be configured
with MPS=128 and be susceptible to the defect.

Remove the Kconfig settings to simplify the MPS code.  If we can identify
the WiFi device in question, we may be able to make a generic quirk to
avoid the problem on all system.

This is not a fix and should not be backported to previous kernels.

Subject: [PATCH 0213/5214] usb: typec: mux: ps883x: Power the retimer off when
 not in use

When there's nothing going through the retimer, there's no reason to
keep it online. Put it in reset when possible to save power.

Also, remove the register cache-compare optimization as it makes little
sense now that the chip resets during almost all transitions and
tracking the validity of that cache becomes a headache.

Subject: [PATCH 0214/5214] usb: typec: intel_pmc_mux: combine kzalloc +
 kcalloc

A flexible array member can be used to combine allocations and simplify
handling slightly.

Add __counted_by for extra runtime analysis.

Subject: [PATCH 0216/5214] usb: udc: pxa: remove unused platform_data

None of the remaining boards put useful data into the platform_data
structures, so effectively this only works with DT based probing.

Remove all code that references this data, to stop using the legacy
gpiolib interfaces. The pxa27x version already supports gpio
descriptors, while the pxa25x version now does it the same way.

Subject: [PATCH 0218/5214] remoteproc: Dead code cleanup in Kconfig for
 STM32_RPROC

There is already an 'if REMOTEPROC' condition wrapping this config option,
making the 'depends on REMOTEPROC' statement a duplicate dependency
(dead code).

I propose leaving the outer 'if REMOTEPROC...endif' and removing the
individual 'depends on REMOTEPROC' statement.

This dead code was found by kconfirm, a static analysis tool for Kconfig.

Subject: [PATCH 0219/5214] dt-bindings: clock: qcom: document the Milos GX
 clock controller

Qualcomm GX(graphics) is a clock controller which has PLLs, clocks and
Power domains (GDSC), but the requirement from the SW driver is to use
the GDSC power domain from the clock controller to recover the GPU
firmware in case of any failure/hangs. The rest of the resources of the
clock controller are being used by the firmware of GPU. This module
exposes the GDSC power domains which helps the recovery of Graphics
subsystem.

Milos can reuse the qcom,kaanapali-gxclkctl.h header due to similarity
of the hardware block, and also reuse of the Linux driver.

Subject: [PATCH 0220/5214] clk: qcom: Add support for GXCLK for Milos

GXCLKCTL (Graphics GX Clock Controller) is a block dedicated to managing
clocks for the GPU subsystem on GX power domain. The GX clock controller
driver manages only the GX GDSC and the rest of the resources of the
controller are managed by the firmware.

We can use the existing kaanapali driver for Milos as well since the
GX_CLKCTL_GX_GDSC supported by the Linux driver requires the same
configuration.

Subject: [PATCH 0222/5214] dt-bindings: clock: amlogic: t7: Add missing mpll3
 parent clock

The mpll3 clock is one parent clock of the sd_emmc and mipi_isp clocks
on the Amlogic T7 SoC, but was missing from t7-peripherals-clkc.yaml
bindings. Add the mpll3 clock source to the T7 peripherals clock
controller input clock list, so that sd_emmc and mipi_isp can use it.

For logical consistency, place the required mpll3 entry before the
optional entry.

This change breaks the ABI, but while the amlogic,t7-peripherals-clkc
bindings have been merged upstream, the corresponding DT has not been
merged yet. Thus, no real users or systems are affected.

Subject: [PATCH 0223/5214] pinctrl: tegra: Enable easier compile testing

Currently NVIDIA Tegra pin controller drivers cannot be compile tested,
unless ARCH_TEGRA is selected.  That partially defeats the purpose of
compile testing, since ARCH_TEGRA is pulled when building platform
kernels.  Solve it and allow compile testing independently of ARCH_TEGRA
choice which requires few less usual changes:

1. Descent in Makefile in to drivers/pinctrl/tegra/ unconditionally,
   because there is no menu option.

2. Depend on COMMON_CLK for PINCTRL_TEGRA20, because it uses
   clk_register_mux().

Since inception in commit 4d3d0e4272d8 ("pinctrl: Add core support for
Aspeed SoCs"), the Aspeed pin controller drivers cannot be compile
tested, unless ARCH_ASPEED is selected.  .  That partially defeats the
purpose of compile testing, since ARCH_ASPEED is pulled when building
platform kernels.

Subject: [PATCH 0226/5214] pinctrl: vt8500: Enable compile testing

Enable compile testing for Realtek pin controller drivers for increased
build and static checkers coverage.  PINCTRL_WMT uses
gpiochip_get_data(), thus needs GPIOLIB.

Subject: [PATCH 0227/5214] dt-bindings: pinctrl: nvidia,tegra234: Add missing
 required block

Binding should require 'reg' property, because address space cannot be
missing in the hardware and is already needed by the Linux drivers.
Require also 'compatible' by convention, although it is not strictly
necessary.

Subject: [PATCH 0232/5214] dt-bindings: pinctrl: qcom,eliza-tlmm: Split QUP
 lane mirror alternates

Several QUP lanes have MIRA/MIRB mirror routings that let the same lane
be muxed out on alternative GPIOs. On Eliza these were all collapsed
under the base function name (e.g. qup1_se6), which prevented boards
from selecting the mirror variants.

Add explicit function names for each mirror lane, matching the pattern
already established by qcom,sm8550-tlmm and related bindings.

Subject: [PATCH 0234/5214] pinctrl: qcom: eliza: Split QUP lane mirror
 alternates

Several QUP lanes have MIRA/MIRB mirror routings which are collapsed
under a single function name (e.g. qup1_se6).

This is an issue because it means there are multiple functions defined
for a given pin that share the same name:

[42] = PINGROUP(42, qup1_se6, qup1_se2, qup1_se6...

So when you select pin 42 and request function qup1_se6, it will select
the first instance of it in this group, which just happens to be
QUP1_SE6_L2, making the second instance (QUP1_SE6_L1_MIRA) effectively
unreachable.

Split each of these lanes that has an alternative GPIO into their own
function so they can actually be selected, following the pattern seen
in pinctrl-sm8550.c.

Subject: [PATCH 0235/5214] pinctrl: qcom: eliza: Split QUP1_SE4 lanes

QUP1_SE4 shares GPIO_36 & GPIO_37 for both L0/L1 and L3/L2 so the
function name cannot be the same or the alternate function cannot
be selected.

Split them up into individual lane functions so boards can specify.

In parse_fw_cfg(), if fwnode_property_match_property_string() fails with

Use __free(bitmap) for automatic cleanup to fix the leak.

Subject: [PATCH 0240/5214] KVM: VMX: more cleanups to __vmx_vcpu_run

Slightly improve register allocation, loading vmx only once
before vmlaunch/vmresume.

This also makes the code slightly more similar to the one for
AMD processors, in that both keep the pointer to struct vcpu_vmx
or vcpu_svm in %rdi.  The code for restoring the guest value of
SPEC_CTRL is also the same for Intel and AMD.

Subject: [PATCH 0241/5214] KVM: SVM: prepare for making SPEC_CTRL switch
 common with VMX

Remove the local labels and restrict RESTORE_*_BODY to just
the restore code itself.  Since the alternatives are different
between VMX and SVM, having labels in the per-vendor file and
jumps in another would be too confusing.

Subject: [PATCH 0243/5214] KVM: SVM: adopt the same VMX_RUN_* flags as VMX

Rename VMX_RUN_* to KVM_ENTER_* (to not confuse with KVM_RUN_* that
already exists) and replace SVM's spec_ctrl_intercepted with that same
bitmask.

Note that KVM_ENTER_SAVE_SPEC_CTRL has the opposite polarity compared
to spec_ctrl_intercepted.  That is, the guest value of the MSR must be
saved if it writes are *not* intercepted.

Subject: [PATCH 0246/5214] KVM: VMX: replace vmx_spec_ctrl_restore_host with
 RESTORE_HOST_SPEC_CTRL_BODY

Reuse the same assembly as SVM, just with alternatives instead
of cpu_feature_enabled(X86_FEATURE_KERNEL_IBRS).

Note that Intel does need an LFENCE with eIBRS, unlike AMD's AutoIBRS.
However, it is not needed for X86_FEATURE_KERNEL_IBRS because there
are no conditional branches between FILL_RETURN_BUFFER and ret.

Subject: [PATCH 0247/5214] platform/x86: use u8 * for raw byte buffers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The buffer parameters in populate_{security,string}_buffer() and
call_{biosattributes,password}_interface() are raw byte buffers, not
character strings - use 'u8 *' instead of 'char *' to reflect this.

Update the local buffer variables at the call sites and in
populate_security_buffer() accordingly.

Subject: [PATCH 0248/5214] platform/x86: dell_rbu: use strscpy in
 image_type_write
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

strcpy() has been deprecated [1] because it performs no bounds checking
on the destination buffer, which can lead to buffer overflows. While the
current code works correctly, replace strcpy() with the safer strscpy()
to follow secure coding best practices.

Subject: [PATCH 0249/5214] dt-bindings: remoteproc: imx-rproc: Support i.MX94

Add compatible string for:
 Cortex-M7 core[0,1] in i.MX94
 Cortex-M33 Sync core in i.MX94

To i.MX94, Cortex-M7 core0 and core1 have different memory view from
Cortex-A55 core, so different compatible string is used.

Subject: [PATCH 0250/5214] remoteproc: imx_rproc: Program non-zero SM CPU/LMM
 reset vector

Cortex-M[7,33] processors use a fixed reset vector table format:

  0x00  Initial SP value
  0x04  Reset vector
  0x08  NMI
  0x0C  ...
  ...
  IRQ[n]

In ELF images, the corresponding layout is:

reset_vectors:  --> hardware reset address
        .word __stack_end__
        .word Reset_Handler
        .word NMI_Handler
        .word HardFault_Handler
        ...
        .word UART_IRQHandler
        .word SPI_IRQHandler
        ...

Reset_Handler:  --> ELF entry point address
        ...

The hardware fetches the first two words from reset_vectors and populates
SP with __stack_end__ and PC with Reset_Handler. Execution proceeds from
Reset_Handler.

However, the ELF entry point does not always match the hardware reset
address. For example, on i.MX94 CM33S:

  ELF entry point:     0x0ffc211d
  hardware reset base: 0x0ffc0000 (default reset value, sw programmable)

Current driver always programs the reset vector as 0. But i.MX94 CM33S's
default reset base is 0x0ffc0000, so the correct reset vector must be
passed to the SM API; otherwise the M33 Sync core cannot boot successfully.

rproc_elf_get_boot_addr() returns the ELF entry point, which is not the
hardware reset vector address. Fix the issue by deriving the hardware reset
vector locally using a SoC-specific mask:

  reset_vector = rproc->bootaddr & reset_vector_mask

The ELF entry point semantics remain unchanged. The masking is applied only
at the point where the SM reset vector is programmed.

Add reset_vector_mask = GENMASK_U32(31, 16) to the i.MX95 M7 configuration
so the hardware reset vector is derived correctly. Without this mask, the
SM reset vector would be programmed with an unaligned ELF entry point and
the M7 core would fail to boot.

strcpy() has been deprecated¹ because it performs no bounds checking on
the destination buffer, which can lead to buffer overflows. While the
current code works correctly, replace strcpy() with the safer strscpy()
to follow secure coding best practices.

Subject: [PATCH 0254/5214] platform/x86: thinkpad_acpi: Remove unneeded goto
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove an unneeded goto statement in hotkey_kthread(). Since
the function has a single exit location with no cleanup code,
the jump provides no benefit. Per the kernel coding style,
returning directly is preferred over goto in such case [1].

Subject: [PATCH 0255/5214] clk: mvebu: use kzalloc_flex

Use a flexible array member to combine kzalloc and kcalloc in one
allocation so they can be freed together.

Add __counted_by for extra runtime analysis. Move counting variable
assignment right after allocation as done by kzalloc_flex with GCC >=
15.

 of_clk_bulk_get()

pr_err() can be replace with dev_err_probe() which will check if error
code is -EPROBE_DEFER. For that the dev pointer has to be passed along.

Subject: [PATCH 0261/5214] clk: mediatek: add MUX_CLR_SET macro

Some MediaTek SoCs (e.g. MT7988) define infra muxes that have neither
a clock gate nor an update register.

Add a MUX_CLR_SET convenience macro that takes only the mux register
offsets, bit shift, and width, hardcoding upd_ofs = 0 and
upd_shift = -1 so callers cannot accidentally pass bogus sentinel
values to wrongly-typed fields.

Subject: [PATCH 0262/5214] clk: mediatek: mt8192: use MUX_CLR_SET

The mfg_pll_sel mux has neither a clock gate nor an update register,
and upd_ofs is stored as u32, so the -1 truncates to 0xFFFFFFFF.

While upd_shift being -1 (as s8) prevents the update path from
executing at runtime, the bogus upd_ofs value is still stored in the
struct.

Use MUX_CLR_SET to avoid passing sentinel values to wrongly-typed
fields.

Subject: [PATCH 0263/5214] clk: mediatek: mt7988: use MUX_CLR_SET for
 gate-less muxes

All 19 muxes in the infra_muxes[] array are pure mux selectors without
a clock gate or update register, yet they were defined using
MUX_GATE_CLR_SET_UPD with gate_shift = -1.

This macro assigns mtk_mux_gate_clr_set_upd_ops, whose
enable/disable/is_enabled callbacks perform BIT(gate_shift). Since
gate_shift is stored as u8, the -1 truncates to 255, causing a
shift-out-of-bounds at runtime:

UBSAN: shift-out-of-bounds in drivers/clk/mediatek/clk-mux.c:76:8
shift exponent 255 is too large for 64-bit type 'long unsigned int'

UBSAN: shift-out-of-bounds in drivers/clk/mediatek/clk-mux.c:102:4
shift exponent 255 is too large for 64-bit type 'long unsigned int'

UBSAN: shift-out-of-bounds in drivers/clk/mediatek/clk-mux.c:122:16
shift exponent 255 is too large for 64-bit type 'long unsigned int'

Switch these definitions to MUX_CLR_SET, which uses
mtk_mux_clr_set_upd_ops (no gate callbacks) and does not require
callers to pass sentinel values for unused update register fields.
The actual clock gating for these peripherals is handled by the
separate GATE_INFRA* definitions further down.

 at client resource allocation

The add_client_resource() function returns zero at success or negative
value at error. The critical section is already protected by
scoped_guard() macro. In this case, the programming pattern of early
return improves code readability.

Subject: [PATCH 0271/5214] firewire: core: code refactoring to queue work item
 for iso_resource

The add_client_resource() function checks the type of client resource
every time to be called. If the type is for iso_resource, it schedules
work item.

However, the iso_resource client resource is only added by the call of
init_iso_resource(). There is no need to check the type every time adding
any client resource.

Subject: [PATCH 0273/5214] firewire: core: split functions for iso_resource
 once operation

Unlike FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE operation, the operations of
FW_CDEV_IOC_[DE]ALLOCATE_ISO_RESOURCE_ONCE require no client resource,
thus they keeps no handle value.

This commit adds the series of functions to separate these operations,
according to divide-and-conquer methodology.

This commit adds _auto suffix to functions for the another type so that
it is easily to distinguish them.

The init_iso_resource function is only called by
ioctl_allocate_iso_resource(), thus no need to be unique.

This commit unifies them with minor code refactoring.

Subject: [PATCH 0277/5214] gpiolib: acpi: Only trigger ActiveBoth interrupts
 on boot

Commit ca876c7483b6 ("gpiolib-acpi: make sure we trigger edge events at
least once on boot") introduced logic to trigger edge-based GPIO
interrupts during initialization to ensure proper initial state setup
when firmware doesn't initialize it.

However, according to the Microsoft GPIO documentation, triggering GPIO
interrupts during initialization should only happen for interrupts
marked as ActiveBoth (both IRQF_TRIGGER_RISING and IRQF_TRIGGER_FALLING)
and only when the associated GPIO line is already asserted (logic level
low).

The current implementation incorrectly triggers:
1. Any edge-triggered interrupt (RISING-only or FALLING-only)
2. RISING interrupts when value is high and FALLING when value is low

This causes problems at bootup for single-edge interrupts that
don't follow the ActiveBoth pattern.

Fix this by:
- Only triggering when BOTH rising and falling edges are configured
- Only triggering when the GPIO line is asserted (value == 0)

Subject: [PATCH 0278/5214] i3c: master: svc: Fix missed IBI after false
 SLVSTART on NPCM845

The NPCM845 I3C controller may raise a false SLVSTART interrupt. The
handler first latches MSTATUS and then clears SLVSTART. If a real IBI
request arrives after the handler latches MSTATUS but before it clears
the SLVSTART interrupt status, HW sets the SLVREQ state. However, the
handler still relies on the stale MSTATUS snapshot, returns early, and
misses the real IBI. No further interrupt is generated for this pending
IBI.

Re-read MSTATUS to obtain the latest state and avoid missing a real IBI
due to this race condition.

Subject: [PATCH 0279/5214] i3c: master: svc: Prevent IRQ storm from false
 SLVSTART on NPCM845

On NPCM845, when a target on the I3C bus gets stuck holding SDA low,
the controller reports a false Master Request (MR) in-band interrupt
event. The driver handles this by emitting a STOP condition to restore
the bus.

However, the hardware quirk SVC_I3C_QUIRK_FALSE_SLVSTART indicates that
emitting a STOP condition may spuriously set the SLVSTART interrupt
status bit. In the Master Request case, this creates a feedback loop:
the STOP triggers a new SLVSTART event, the IRQ handler fires again,
the controller still reports an MR type, another STOP is emitted, and
the cycle repeats indefinitely, resulting in an IRQ storm that can lock
up the CPU.

Clear the SLVSTART status bit explicitly after emitting the STOP in the
Master Request IBI handler when the SVC_I3C_QUIRK_FALSE_SLVSTART quirk
is set. This breaks the feedback loop without affecting normal SLVSTART
processing, which is already guarded in the top-level IRQ handler by
checking that MSTATUS is in SLVREQ state.

Subject: [PATCH 0281/5214] i3c: dw-i3c-master: Fix IBI count register
 selection for versalnet

On DesignWare I3C controllers where IC_HAS_IBI_DATA=0 (such as versalnet),
the IBI_STS_CNT field (bits [28:24] of QUEUE_STATUS_LEVEL) is hardwired
to 0. The IBI status entry count is instead reported via IBI_BUF_BLR
(bits [23:16] of the same register).

irq_handle_ibis() was unconditionally reading IBI_STS_CNT, causing it to
always see 0 pending IBIs on versalnet and return early without draining
the IBI buffer. Since INTR_IBI_THLD_STAT is level-triggered against the
buffer fill level, this left the interrupt permanently asserted.

Detect IBI data capability at probe time by writing the IBI data threshold
field in QUEUE_THLD_CTRL and reading it back. Use the result to select the
correct register field in irq_handle_ibis().

Subject: [PATCH 0282/5214] pinctrl: mediatek: eint: Drop base from
 mtk_eint_chip_write_mask()

When support for multiple EINT base addresses was added in commit
3ef9f710efcb ("pinctrl: mediatek: Add EINT support for multiple
addresses"), mtk_eint_chip_write_mask() was changed to write interrupt
masks for all base addresses in one call. However the "base" parameter
was left around and now causes sparse warnings:

    mtk-eint.c:428:44: warning: incorrect type in argument 2 (different address spaces)
    mtk-eint.c:428:44:    expected void [noderef] __iomem *base

    mtk-eint.c:436:44:    got void [noderef] __iomem **base

Since the "base" parameter is no longer needed, just drop it.

Subject: [PATCH 0284/5214] fs/ntfs3: add depth limit to indx_find_buffer to
 prevent stack overflow

indx_find_buffer() recursively descends the B+ tree index with no depth
limit.  A crafted NTFS image with circular index node references causes
unbounded recursion, overflowing the kernel stack and panicking the
system.

This is reachable by mounting a malicious NTFS filesystem (e.g. from a
USB drive via desktop automount) and deleting a file whose index entry
triggers the rebalancing fallback path in indx_delete_entry().

Add a depth parameter and bail out with -EINVAL when it reaches the
fnd->nodes array bound, matching the constraint already enforced by
fnd_push() in indx_find().

The related function indx_find() was previously patched for a similar
infinite-loop issue (commit 1732053c8a6b), but indx_find_buffer() was
missed.

Subject: [PATCH 0285/5214] ntfs3: bound to_move in indx_insert_into_root
 before hdr_insert_head

indx_insert_into_root() promotes a full resident $INDEX_ROOT into
$INDEX_ALLOCATION and copies all non-last resident root entries into
a newly allocated INDEX_BUFFER via hdr_insert_head(). The source
byte count 'to_move' is summed from the on-disk resident entry sizes
and is independent of the destination buffer size, which comes from
root->index_block_size (via indx->index_bits).

A crafted NTFS image that keeps a valid, full resident root but
shrinks root->index_block_size down to 512 after the root has been
populated makes hdr_insert_head() memcpy attacker-controlled resident
entry bytes past the end of the kmalloc(1u << indx->index_bits)
allocation returned by indx_new(). For a 512-byte destination and a
resident root whose non-last entries total 560 bytes, the memcpy
overruns by 120 bytes and a following memmove extends the highest
written offset to 136 bytes past the allocation. The overflow bytes
are a direct copy of on-disk entries (via kmemdup), so they are
fully attacker-controlled.

The write is reachable from unprivileged open(O_CREAT) on a mounted
crafted NTFS image: a single sufficiently long create in a directory
whose resident root is already full forces root promotion and
triggers the copy.

This is a controlled out-of-bounds write of 120-136 bytes past a
kmalloc(index_block_size) allocation, with attacker-controlled
content. It is a bounded adjacent-heap corruption primitive; it is
not an arbitrary-address write. Successful exploitation into a named
victim object depends on the surrounding slab layout.

Reject the copy at the sink. The destination's INDEX_HDR already
reports hdr_total (the payload capacity of the new buffer) and
hdr_used (the bytes already consumed by the terminal END entry
installed by indx_new()); require that to_move fits in the remaining
payload before calling hdr_insert_head(). On mismatch, fail with
-EINVAL and mark the filesystem as having a detected on-disk
inconsistency, which is the same behaviour as the surrounding
validation in this function.

Subject: [PATCH 0287/5214] ntfs3: validate split-point offset in
 indx_insert_into_buffer

indx_insert_into_buffer() computes

    used = used1 - to_copy - sp_size;
    memmove(de_t, Add2Ptr(sp, sp_size), used - le32_to_cpu(hdr1->de_off));

where sp and sp_size come from hdr_find_split().  hdr_find_split()
walks entries by le16_to_cpu(e->size) without validating that each
step stays within hdr->used or that the size field is at least
sizeof(struct NTFS_DE).  index_hdr_check(), the on-load gatekeeper,
only validates header-level fields (used, total, de_off) and does
not walk per-entry sizes.

A crafted NTFS image whose leaf INDEX_HDR reports used == total but
contains one interior NTFS_DE with size = 0xFFF0 therefore passes
validation, descends to indx_insert_into_buffer() through the
ntfs_create() -> indx_insert_entry() path, and makes hdr_find_split()
return an sp whose sp_size (0xFFF0) greatly exceeds the remaining
bytes in the buffer.  The u32 subtraction underflows and the memmove
count becomes a near-4-GiB value, producing an out-of-bounds kernel
write that corrupts adjacent allocations and panics the kernel.

Reproduced on 7.0.0-rc7 with UML + KASAN via a crafted image and a
single 'touch' inside the mounted directory; crash site resolves to
fs/ntfs3/index.c at the memmove.  Trigger requires only local mount
of an attacker-supplied filesystem image (USB, loopback, or removable
media auto-mount).

Reject the split whenever the chosen sp plus its declared size
already extends past hdr1->used.  This is the minimal fix; it
preserves the existing hdr_find_split() contract and relies on the
same out: cleanup path as the pre-existing error returns.

A prior OOB read in the very same indx_insert_into_buffer() memmove
was fixed in commit b8c44949044e ("fs/ntfs3: Fix OOB read in
indx_insert_into_buffer") by tightening hdr_find_e(), but that fix
does not cover the split-point size field path addressed here: sp is
returned by hdr_find_split(), not hdr_find_e(), and the underflow is
driven by sp->size rather than hdr->used exceeding hdr->total.

Support for ISA bus mastering was removed a few years ago, and the VLB
mode does not use the ISA DMA API, so drop the dependency and the header
inclusion.

Subject: [PATCH 0292/5214] scsi: ncr53c8xx: Drop CONFIG_ prefix from
 Zalon-specific compiler defines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

kconfiglint reports:

  X001: CONFIG_NCR53C8XX_PREFETCH referenced in Makefile but not
        defined in any Kconfig
  X001: CONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS referenced in Makefile
        but not defined in any Kconfig

The ncr53c8xx SCSI driver uses two preprocessor defines that carry the
CONFIG_ prefix but are not defined in any Kconfig file:

  -DCONFIG_NCR53C8XX_PREFETCH
  -DCONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS

These are hardcoded compiler flags in drivers/scsi/Makefile, passed only
when CONFIG_SCSI_ZALON is enabled:

  ncr53c8xx-flags-$(CONFIG_SCSI_ZALON) \
      := -DCONFIG_NCR53C8XX_PREFETCH -DSCSI_NCR_BIG_ENDIAN \
          -DCONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS

The source files ncr53c8xx.c and ncr53c8xx.h check these defines with
#ifdef to enable script prefetching and disable 16-bit word transfers
respectively — both specific to the PA-RISC Zalon SCSI controller's
big-endian bus requirements.

These defines have been present since the initial git import in commit
1da177e4c3f4 ("Linux-2.6.12-rc2"). They predate the modern Kconfig
convention that CONFIG_ prefixed symbols should always originate from
Kconfig. The third define on the same line, SCSI_NCR_BIG_ENDIAN, already
correctly omits the CONFIG_ prefix.

The CONFIG_ prefix is misleading: these are not user-configurable
options and do not appear in any Kconfig menu. They are unconditionally
enabled for all Zalon builds. Remove the CONFIG_ prefix from both
symbols — renaming them to NCR53C8XX_PREFETCH and
SCSI_NCR53C8XX_NO_WORD_TRANSFERS — to match the convention used by
SCSI_NCR_BIG_ENDIAN on the same line and to avoid confusion with actual
Kconfig-managed symbols.

No functional change.

 UFS Host Controller

SA8797P is the automotive variant of the Nord SoC. Like SA8255P, its
platform firmware implements an SCMI server that manages UFS resources
such as the PHY, clocks, regulators and resets via the SCMI power
protocol. As a result, the OS-visible DT only describes the controller's
MMIO, interrupt, IOMMU and power-domain interfaces, making SA8255P the
appropriate fallback compatible.

Subject: [PATCH 0295/5214] KVM: TDX/VMX: rework
 EPT_VIOLATION_EXEC_FOR_RING3_LIN into PROT_MASK

EPT exit qualification bit 6 is used when mode-based execute control
is enabled, and reflects user executable addresses. Rework name to
reflect the intention and add to EPT_VIOLATION_PROT_MASK, which allows
simplifying the return evaluation in
tdx_is_sept_violation_unexpected_pending a pinch.

Rework handling in __vmx_handle_ept_violation to unconditionally clear
EPT_VIOLATION_PROT_USER_EXEC until MBEC is implemented, as suggested by
Sean [1].

Note: Intel SDM Table 29-7 defines bit 6 as:
  If the "mode-based execute control" VM-execution control is 0, the
  value of this bit is undefined. If that control is 1, this bit is the
  logical-AND of bit 10 in the EPT paging-structure entries used to
  translate the guest-physical address of the access causing the EPT
  violation. In this case, it indicates whether the guest-physical
  address was executable for user-mode linear addresses.

Update SPTE_MMIO_ALLOWED_MASK to allow EPT user executable (bit 10) to
be treated like EPT RWX bit2:0, as when mode-based execute control is
enabled, bit 10 can act like a "present" bit.  Likewise do not include
it in FROZEN_SPTE.

No functional changes intended, other than the reduction of the maximum
MMIO generation that is stored in page tables.

Subject: [PATCH 0298/5214] KVM: x86/mmu: shuffle high bits of SPTEs in
 preparation for MBEC

Access tracking will need to save bit 10 when MBEC is enabled.
Right now it is simply shifting the R and X bits into bits 54 and 56,
but bit 10 would not fit with the same scheme.  Reorganize the
high bits so that access tracking will use bits 52, 54 and 62.
As a side effect, the free bits are compacted slightly, with
56-59 still unused.

Subject: [PATCH 0302/5214] PCI: endpoint: Add auxiliary resource query API

Endpoint controller drivers may integrate auxiliary blocks (e.g. DMA
engines) whose register windows and descriptor memories metadata need to
be exposed to a remote peer. Endpoint function drivers need a generic
way to discover such resources without hard-coding controller-specific
helpers.

Add pci_epc_get_aux_resources_count() / pci_epc_get_aux_resources() and
the corresponding pci_epc_ops callbacks. The count helper returns the
number of available resources, while the get helper fills a
caller-provided array of resources described by type, physical address
and size, plus type-specific metadata.

Subject: [PATCH 0303/5214] PCI: dwc: Record integrated eDMA register window

Some DesignWare PCIe controllers integrate an eDMA block whose registers
are located in a dedicated register window.

The EP-side aux-resource code exposes an interrupt-emulation doorbell
register (DOORBELL_MMIO) from that window. Its location is derived from
the start of the eDMA register window plus the doorbell offset already
provided by dw-edma, and the window size is used to validate the
computed register location.

Record the physical base and size of the integrated eDMA register window
in struct dw_pcie so the EP-side DesignWare aux-resource provider can
construct that doorbell resource.

Subject: [PATCH 0304/5214] PCI: dwc: ep: Expose integrated eDMA resources via
 EPC aux-resource API

Implement the EPC aux-resource API for DesignWare endpoint controllers
with integrated eDMA.

Currently, only report an interrupt-emulation doorbell register
(PCI_EPC_AUX_DOORBELL_MMIO), including its Linux IRQ and the write data
needed to trigger the interrupt.

If the DMA controller MMIO window is already exposed via a
platform-owned fixed BAR subregion, also provide the BAR number and
offset so EPF drivers can reuse it without reprogramming the BAR.

Subject: [PATCH 0305/5214] PCI: endpoint: pci-ep-msi: Refactor doorbell
 allocation for new backends

Prepare pci-ep-msi for non-MSI doorbell backends.

Factor MSI doorbell allocation into a helper and extend struct
pci_epf_doorbell_msg with:

  - irq_flags: required IRQ request flags (e.g. IRQF_SHARED for some
    backends)
  - type: doorbell backend type
  - bar/offset: pre-exposed doorbell target location, if any

Initialize these fields for the existing MSI-backed doorbell
implementation.

Also add PCI_EPF_DOORBELL_EMBEDDED type, which is to be implemented in a
follow-up patch.

No functional changes.

Subject: [PATCH 0306/5214] remoteproc: xlnx: Check remote core state

The remote state is set to RPROC_DETACHED if the resource table is found
in the memory. However, this can be wrong if the remote is not started,
but firmware is still loaded in the memory. Use PM_GET_NODE_STATUS call
to the firmware to request the state of the RPU node. If the RPU is
actually out of reset and running, only then move the remote state to
RPROC_DETACHED, otherwise keep the remote state to RPROC_OFFLINE.

Use a flexible array member to combine allocations. Simplifies memory
management.

Add __counted_by for extra runtime analysis. Also move counting variable
assignment up as required by __counted_by.

The BYTE_MASK macro is the central point of the black magic
in update_permission_bitmask().  Rename it to something
that relates to how it is used, and add a comment explaining
how it works.

Using shifts instead of powers of two was actually suggested by
David Hildenbrand back in 2017 for clarity[1] but I evidently
forgot his suggestion when applying to kvm.git.

Subject: [PATCH 0313/5214] firewire: core: reduce critical section duration in
 pre-processing of isoc resource management in cdev

It is preferable for the critical section to be as small as possible.
Current implementation of iso_resource_auto_work() function uses a
spinlock to control concurrent access to members of fw_card, fw_device,
iso_resource_auto structures, however the locking duration could be
reduced.

This commit refactors to shorten that duration.

Subject: [PATCH 0314/5214] firewire: core: use switch statement for
 post-processing of isoc resource management in cdev

The iso_resource_auto structure object has three states. The current
implementation of state evaluation before managing the actual isochronous
resources can be improved.

This commit refactors the evaluation logic using a switch statement.

 stream is valid

In sdw_stream_remove_slave() check that stream is a valid pointer
before passing it to functions that dereference it. Return 0 if the
pointer is invalid.

This is a convenience for callers. They can safely call this function
during cleanup code without needing a pointer validity check duplicated
at every call point.

 detection logic

Read USB2_ADPCTRL once in rcar_gen3_check_id() instead of issuing
multiple MMIO reads, and derive both IDDIG and VBUSVALID from the same
value.

Drop the redundant !! operator, as assigning a masked u32 value to a
bool already performs the required normalization. Simplify the logic by
comparing the ID and VBUS status directly, which is equivalent to the
previous conditional but easier to follow.

Subject: [PATCH 0323/5214] media: v4l2-ctrls: validate HEVC active reference
 counts

HEVC slice parameters are shared stateless V4L2 controls, but the common
validation path does not verify the active L0/L1 reference counts before
driver-specific code consumes them.

The original report came from Cedrus, but the active count bounds are
not Cedrus-specific. Validate them in the common HEVC slice control path
so stateless HEVC drivers get the same basic guarantees as soon as the
control is queued.

Do not reject ref_idx_l0/ref_idx_l1 entries here. Existing userspace may
use out-of-range sentinel values such as 0xff for missing references, and
some hardware can use that information for concealment. Keep this common
check limited to the active reference counts.

Subject: [PATCH 0324/5214] media: cedrus: skip invalid H.264 reference list
 entries

Cedrus consumes H.264 ref_pic_list0/ref_pic_list1 entries from the
stateless slice control and later uses their indices to look up
decode->dpb[] in _cedrus_write_ref_list().

Rejecting such controls in cedrus_try_ctrl() would break existing
userspace, since stateless H.264 reference lists may legitimately carry
out-of-range indices for missing references. Instead, guard the actual
DPB lookup in Cedrus and skip entries whose indices do not fit the fixed
V4L2_H264_NUM_DPB_ENTRIES array.

This keeps the fix local to the driver use site and avoids out-of-bounds
reads from malformed or unsupported reference list entries.

Subject: [PATCH 0326/5214] media: mtk-jpeg: cancel workqueue on release for
 supported platforms only

Since a recent fix the mtk_jpeg_release function cancels any pending
or running work present in the driver workqueue using
cancel_work_sync function.
Currently, only the multicore based variants use this workqueue and they
have the jpeg_worker platform data field initialized with a workqueue
callback function. For the others, this field value remain NULL by
default.
The cancel_work_sync function is unconditionally called in
mtk_jpeg_release function, even for the variants that do not use the
workqueue. This call generates a WARN_ON print in __flush_work because
the workqueue callback function presence check fails in __flush_work
function (used by cancel_work_sync).

So, to avoid these warnings, call cancel_work_sync only if a workqueue
callback is defined in platform data.

Subject: [PATCH 0327/5214] media: chips-media: wave5: Move src_buf Removal to
 finish_encode

During encoder processing, there is a case where the IRQ response could
return the buffer back to userspace via v4l2_m2m_buf_done call. In this
time, userspace could queue up this same buffer before start_encode removes
the index from the ready queue. This would then lead to a case where the
buffer in the ready queue could be a self loop due to the
WRITE_ONCE(prev->next, new) call in __list_add.

When __list_del is finally called, the loop is already made so nothing
points back to ready queue list head and pointers are poisoned.

A buffer should not be marked as DONE before the buffer is removed from
m2m ready queue. Move removal entirely to finish_encode.

Subject: [PATCH 0332/5214] media: verisilicon: Export only needed pixels
 formats

Some pixel formats can only be produced if the decoder outputs
reference pictures directly. In some cases, such as AV1 film-grain,
the use of the post-processor is strictly required. In this case,
only enumerate the post-processor supported formats. The exception is
when V4L2_FMTDESC_FLAG_ENUM_ALL is set, in this case, we enumerate
everything regardless of the state.

Subject: [PATCH 0333/5214] media: rkvdec: Introduce a global bitwriter helper

The use of structures with bitfields is good when the values are
somewhat aligned.
More mis-alignement means that compilers need to do more gymnastics
to edit the fields values.

Some cases have been reported with CLang on specific architectures
like armhf and hexagon, where the compiler would allocate a bigger
local stack than needed or even completely freeze during compilation.

Some fixes have been provided to ease the issues, but the real fix
here is to use a bitwriter instead of heavily unaligned bitfields.

This is a preparation commit to provide a global bitwriter interface
for the whole driver.

Subject: [PATCH 0335/5214] media: rkvdec: common: Drop bitfields for the
 bitwriter

Currently, the common code files for hevc and h264 use structs with
bitfields to represent the HW RPS buffer.

Because the bitfields are mostly unaligned and numerous, it brings compiler
issues, especially with clang.

To prevent that, switch to using the global bitwriter previously
introduced instead.

Subject: [PATCH 0336/5214] media: rkvdec: vdpu383: Drop bitfields for the
 bitwriter

The VDPU383 support for hevc and h264 use structs with bitfields to
represent the SPS and PPS.

Because the fields are mostly unaligned and numerous, it brings compiler
issues, especially with clang.

To prevent that, switch to using the global bitwriter previously
introduced instead.

Subject: [PATCH 0337/5214] media: chips-media: wave5: Release m2m_ctx after
 Instance Removed from List

Possible use after free if IRQ thread manages to obtain spinlock between
m2m_ctx release and wave5_release function removing stream instance from
list of active instances. The IRQ thread looks for the m2m_ctx which is
freed so null pointer dereference occurs.

Subject: [PATCH 0338/5214] media: chips-media: wave5: Fix Reports from Kernel
 Lock Validator

handle_dynamic_resolution change requires that the state_lock be acquired
based on the lockdep_assert_held. However, the
handle_dynamic_resolution_change call in initialize_sequence does not
properly obtain the lock before calling.

Since the v4l2_ctrl_find and s_ctrl can sleep, they should not be called
while a lock is already held. Store off the fbc_buf_count then properly
update control once lock has been freed.

Subject: [PATCH 0339/5214] media: cedrus: Fix missing cleanup in error path

According to the documentation struct v4l2_fh has to be cleaned up with
v4l2_fh_exit() before being freed. [1]
Currently there is no actual bug here, when v4l2_fh_exit() isn't called.
v4l2_fh_exit() in this case only destroys internal mutex. But it may
change in the future, when v4l2_fh_init/v4l2_fh_exit will be enhanced.

 probe failure

If V4L2 device fails to register, then SRAM still be claimed and as a
result driver will not be able to probe again.

 cedrus 1c0e000.video-codec: Failed to probe hardware
 cedrus 1c0e000.video-codec: probe with driver cedrus failed with error -16

cedrus_hw_remove undoes everything that was previously done by
cedrus_hw_probe, such as disabling runtime power management and
releasing the claimed SRAM and reserved memory region.

Subject: [PATCH 0349/5214] fpga: ts73xx-fpga: add OF match table for device
 tree probing

The ts73xx-fpga driver currently only matches by platform device name,
which prevents it from being probed when the device is described in a
device tree. Add an of_device_id table so the driver can match against
the "technologic,ts7300-fpga" compatible string.

The TS-7350 and TS-7390 use different FPGAs with a different programming
interface, so while the driver is named "ts73xx-fpga", it doesn't apply
to them.

Subject: [PATCH 0352/5214] fpga-mgr: Add Efinix SPI programming driver

Add a new driver for loading binary firmware to configuration
RAM using "SPI passive mode" on Efinix FPGAs.

Efinix passive SPI configuration requires chip select to remain asserted
from reset until the complete bitstream and trailing idle clocks have
been transferred, so the driver keeps CS active with cs_change and locks
the SPI bus for the duration of configuration.

Subject: [PATCH 0353/5214] gfs2: fix use-after-free in gfs2_qd_dealloc

gfs2_qd_dealloc(), called as an RCU callback from gfs2_qd_dispose(),
accesses the superblock object sdp through qd->qd_sbd after freeing qd.
It does so to decrement sd_quota_count and wake up sd_kill_wait.

However, by the time the RCU callback runs, gfs2_put_super() may have
already freed sdp via free_sbd().  This can happen when
gfs2_quota_cleanup() is called during unmount: it disposes of quota
objects via call_rcu() and then waits on sd_kill_wait with a 60-second
timeout.  If the timeout expires, or if gfs2_gl_hash_clear() triggers
additional qd_put() calls that schedule more RCU callbacks after the
wait completes, gfs2_put_super() will proceed to free the superblock
while RCU callbacks referencing it are still pending.

Add an rcu_barrier() before free_sbd() in gfs2_put_super() to ensure
all pending RCU callbacks (including gfs2_qd_dealloc) have completed
before the superblock is freed.

Fixes: a475c5dd16e5 ("gfs2: Free quota data objects synchronously")

Subject: [PATCH 0354/5214] clk: renesas: rzv2h: Add PLLDSI clk mux support

Add PLLDSI clk mux support to select PLLDSI clock from different clock
sources.

Introduce the DEF_PLLDSI_SMUX() macro to define these muxes and register
them in the clock driver.

Extend the determine_rate callback to calculate and propagate PLL
parameters via rzv2h_get_pll_dtable_pars() when LVDS output is selected,
using a new helper function rzv2h_cpg_plldsi_smux_lvds_determine_rate().

The CLK_SMUX2_DSI{0,1}_CLK clock multiplexers select between two paths
with different duty cycles:

- CDIV7_DSIx_CLK (LVDS path, parent index 0): asymmetric H/L=4/3 duty (4/7)
- CSDIV_DSIx (DSI/RGB path, parent index 1): symmetric 50% duty (1/2)

Implement rzv2h_cpg_plldsi_smux_{get,set}_duty_cycle clock operations to
allow the DRM driver to query and configure the appropriate clock path
based on the required output duty cycle.

Subject: [PATCH 0356/5214] clk: renesas: r9a09g047: Add CLK_PLLDSI{0,1} clocks

Add support for the PLLDSI{0,1} clocks in the r9a09g047 CPG driver.

Introduce CLK_PLLDSI{0,1} also, introduce the
rzg3e_cpg_pll_dsi{0,1}_limits structures to describe the frequency
constraints specific to the RZ/G3E SoC.

On Renesas RZ/G3E:

 - PLLDSI0 maximum output frequency: 1218 MHz
 - PLLDSI1 maximum output frequency: 609 MHz

These limits are enforced through the newly added
RZG3E_CPG_PLL_DSI{0,1}_LIMITS().

Subject: [PATCH 0359/5214] clk: renesas: r9a09g047: Add support for
 SMUX2_DSI{0,1}_CLK

Add support for the SMUX2_DSI0_CLK and SMUX2_DSI1_CLK clock muxes
present on the r9a09g047 SoC.

These muxes select between CDIV7_DSI{0,1}_CLK and CSDIV_2to16_PLLDSI{0,1}
using the CPG_SSEL3 register (SELCTL0 and SELCTL1 bits).

According to the hardware manual, when LVDS0 or LVDS1 outputs are used,
SELCTL0 or SELCTL1 must be set accordingly.

Subject: [PATCH 0362/5214] mtd: spinand: Use secondary ops for continuous
 reads

In case a chip supports continuous reads, but uses a slightly different
cache operation for these, it may provide a secondary operation template
which will be used only during continuous cache read operations.

From a vendor driver point of view, enabling this feature implies
providing a new set of templates for these continuous read
operations. The core will automatically pick the fastest variant,
depending on the hardware capabilities.

Subject: [PATCH 0363/5214] mtd: spinand: winbond: Add support for continuous
 reads on W25NxxJW

As for the W35NxxJW family, add support for W25N{01,02}JW continuous
read support. Similar operations require to be done, such as setting a
specific bit in a configuration register, and providing a set of read
variants without the address cycles.

As read from cache variants are badly supported by SPI memory
controllers, we create a new set of read from cache templates with a
fake address cycle and just enough dummy cycles. There are two
unsupported configurations (which would require 4.5 dummy bytes), so we
just do not provide them.

The same extra value in the ECC is possible as with the W35NxxJW family,
so we reference the same helper to retrieve the ECC status.

Subject: [PATCH 0364/5214] mtd: spinand: winbond: Add support for continuous
 reads on W35NxxJW

W35N{01,02,04}JW support being read continuously under certain
circumstances. A bit must be set in their configuration register, and
a specific read from cache operation, a bit shorter than usual because
it no longer requires the address cycles, must be used for the occasion.

Setting the "enable" bit is already supported by the core, aside from
the subtlety of making sure the HFREQ bit is also set in octal DTR mode
above 90MHz. However, handling two different read from cache templates
involves creating a list of read from cache variants adapted the
continuous reads, ie. without address cycles.

Unfortunately, these operations, despite being very close to their
original read from cache cousins, are often unsupported by smart SPI
controller drivers because reading from cache historically allowed
changing the offset at which the host would start by providing a 2-byte
column address. In order to prevent issues with this, it has been
decided to implement these variants with a single "ignored" address byte
(respectively two in the octal DTR case), further reducing the amount of
dummy cycles needed before the first bit of data.

Enabling continuous reads has a side effect: the ECC status register now
may also return the value b11, which means that more than 1
uncorrectable error happened during the read. This non standard
behaviour requires to re-implement, almost identically the "get ECC"
helper from the core, with just an extra case for this value (it is
prefixed "w25w35nxxjw" because all these chips have the same behaviour).

Speed gain is substantial, see below. The flash_speed -C benchmark has
been run on a TI AM62A7 LP SK with CPU power management disabled,
mounted with a W35N01JW chip.

Subject: [PATCH 0367/5214] mtd: spinand: winbond: Add support for continuous
 reads on W25NxxJW

As for the W35NxxJW family, add support for W25N{01,02}JW continuous
read support. Similar operations require to be done, such as setting a
specific bit in a configuration register, and providing a set of read
variants without the address cycles.

As read from cache variants are badly supported by SPI memory
controllers, we create a new set of read from cache templates with a
fake address cycle and just enough dummy cycles. There are two
unsupported configurations (which would require 4.5 dummy bytes), so we
just do not provide them.

The same extra value in the ECC is possible as with the W35NxxJW family,
so we reference the same helper to retrieve the ECC status.

All variants have been validated on a Nuvoton MA35D1 platform.

Subject: [PATCH 0368/5214] mtd: spinand: Make sure continuous read is always
 disabled during probe

Recent changes made sure whenever we were using continuous reads, we
would first start by disabling the feature to ensure a well proven and
stable probe sequence. For development purposes, it might also matter to
make sure we always disable continuous reads at first, in case the ECC
configuration would change. Doing this "automatically" will become even
more relevant when we add extra controller flags to prevent continuous
reads at all.

Ensure we disable continuous reads if the feature is available on the
chip, regardless of whether it will be used or not.

Subject: [PATCH 0369/5214] mtd: spinand: Prevent continuous reads on some
 controllers

Some controllers do not have full control over the CS line state and may
deassert it under certain conditions in the middle of a (long)
transfer.

Continuous reads are stopped with a CS deassert, hence both features
cannot live together.

Whenever a controller flags that it cannot maintain the CS state
reliably, disable continuous reads entirely.

Subject: [PATCH 0370/5214] mtd: sm_ftl: allocate cis_buffer with main struct

Use a flexible array member and kzalloc_flex() to do so. Simplifies
memory allocation slightly.

Subject: [PATCH 0371/5214] staging: rtl8723bs: fix stainfo check in
 rtw_aes_decrypt

The null-pointer-guard was incorrect, returning _FAIL on valid pointer.
Invert the guard, so it returns _FAIL on invalid pointer.

Fixes: e23ad1570028 ("staging: rtl8723bs: use guard clause for stainfo check")

Subject: [PATCH 0373/5214] staging: sm750fb: return -ETIMEDOUT on timeout in
 de_wait functions

The hw_sm750le_de_wait() and hw_sm750_de_wait() functions return -1
when a timeout occurs. Replace these with -ETIMEDOUT to use a proper
errno value and better describe the error condition.

All callers check the return value as non-zero, so this change does
not alter existing behavior.

Subject: [PATCH 0374/5214] staging: sm750fb: propagate error codes from
 de_wait()

The sm750 acceleration functions currently return -1 when
de_wait() fails, discarding the original error code.

Since de_wait() now returns proper errno values, propagate
the error code instead of returning -1.

Subject: [PATCH 0376/5214] staging: nvec: fix use-after-free in
 nvec_rx_completed()

In nvec_rx_completed(), when an incomplete RX transfer is detected,
nvec_msg_free() is called to return the message back to the pool by
clearing its 'used' atomic flag. Immediately after this, the code
accesses nvec->rx->data[0] to check the message type.

Since nvec_msg_free() marks the pool slot as available via atomic_set(),
any concurrent or subsequent call to nvec_msg_alloc() could claim that
same slot and overwrite its data[] array. Reading nvec->rx->data[0] after
freeing the message is therefore a use-after-free.

Fix this by saving the message type byte before calling nvec_msg_free(),
then using the saved value for the battery quirk check.

Fixes: d6bdcf2e1019 ("staging: nvec: Add battery quirk to ignore incomplete responses")

Subject: [PATCH 0377/5214] staging: nvec: fix unconditional pm_power_off
 teardown

tegra_nvec_remove() unconditionally sets pm_power_off = NULL, even if
nvec was not the one that registered it. This breaks any other driver
that may have set pm_power_off to its own handler.

Replace the unconditional assignment with a guarded check so that
pm_power_off is only cleared if nvec was the one that set it.

Also remove the stale FIXME comment, as the guard addresses exactly
what it was asking for.

Subject: [PATCH 0382/5214] staging: octeon: convert cvmx_spi_mode_t from
 typedef to plain enum

The Linux kernel coding style discourages the use of typedefs for
enums. Convert cvmx_spi_mode_t to a plain 'enum cvmx_spi_mode' and
update all users across the MIPS Octeon architecture code and the
staging driver stubs.

This is part of a series converting all remaining enum typedefs in
the octeon subsystem to plain enums, improving compliance with the
kernel coding style.

No functional change.

Subject: [PATCH 0385/5214] staging: octeon: convert cvmx_pko_lock_t from
 typedef to plain enum

The Linux kernel coding style discourages the use of typedefs for
enums. Convert cvmx_pko_lock_t to a plain 'enum cvmx_pko_lock' and
update all users across the MIPS Octeon architecture code and the
staging driver stubs.

No functional change.

Subject: [PATCH 0392/5214] staging: rtl8723bs: add function definition arg
 names to rtw_btcoex.h

Adds function definition argument names to rtw_btcoex.h in order to
conform to kernel code style. This eliminates warnings generated by
checkpatch.pl.

In all cases it's the 'struct adapter *' argument which has been given
the name 'padapter'. This matches the names used in the implementations
of these functions.

Subject: [PATCH 0400/5214] staging: rtl8723bs: simplify NULL pointer
 comparisons in rtw_recv.h

Fix checkpatch.pl warnings regarding explicit comparisons to NULL.
The kernel coding style prefers the shorter if (!ptr) idiom over
if (ptr == NULL). Clean up the inline functions in rtw_recv.h to
match this standard.

Subject: [PATCH 0405/5214] staging: rtl8723bs: fix block comment alignment in
 hal_pwr_seq.c

Fix the multi-line block comment at the top of the file to follow
the kernel coding style: each continuation line should start with
' * ' and the closing '*/' should be on its own line without a
preceding blank line.

This fixes the following checkpatch.pl warning:
  WARNING: Block comments should align the * on each line

Subject: [PATCH 0417/5214] staging: rtl8723bs: replace type and rename the
 chip_type field

The 'chip_type' field always accepts one value from the
hal_chip_type_e enumeration: TEST_CHIP or NORMAL_CHIP (FPGA is never
used).
Changing this field's type to bool will allow it to be used directly in
conditions without the need for wrapped macros.

The new type requires a corresponding variable name, so rename it to
'chip_normal' to improve code readability.

Subject: [PATCH 0420/5214] staging: rtl8723bs: remove unused VendorType from
 struct hal_version

The 'VendorType' field of the 'struct hal_version' is set once when the
chip is initialized, but no one ever reads this data, so remove it to
eliminate unused code.

 struct hal_version

'ROMVer' field of 'sturct hal_version' never used anywhere in the
driver, so remove it to eliminate unused code.

Remove the related call to rtw_read32(), the result of which is only
used for 'ROMVer' and is no longer needed.

Subject: [PATCH 0423/5214] staging: rtl8723bs: move normal_chip field to
 struct hal_com_data

The 'chip_normal' field is the only remaining member of the 'struct
hal_version' that is used.

Move this field to the hal_com_data struct, where other chip information
is already stored. The order of assignments and reads to this variable
remains unchanged. This is purely a data relocation patch.

There are two ways to graft resource into resource tree in PCI,
pci_assign_resource() and pci_claim_resource(). Only the former logs
the action, which complicated troubleshooting the cases where resources
are assigned by pci_claim_resource(), which mostly assigns the addresses
inherited from the FW.

Add logging into pci_claim_resource() to make troubleshooting easier.

Subject: [PATCH 0436/5214] PCI: endpoint: pci-epf-vntb: Reuse pre-exposed
 doorbells and IRQ flags

Support doorbell backends where the doorbell target is already exposed
via a platform-owned fixed BAR mapping and/or where the doorbell IRQ
must be requested with specific flags.

When pci_epf_alloc_doorbell() provides db_msg[].bar/offset, reuse the
pre-exposed BAR window and skip programming a new inbound mapping. Also
honor db_msg[].irq_flags when requesting the doorbell IRQ.

Multiple doorbells may share the same Linux IRQ. Avoid duplicate
request_irq() calls by requesting each unique virq once.

Make pci-epf-vntb work with platform-defined or embedded doorbell
backends without exposing backend-specific details to the consumer
layer.

Subject: [PATCH 0437/5214] PCI: endpoint: pci-epf-test: Reuse pre-exposed
 doorbell targets

pci-epf-test advertises the doorbell target to the RC as a BAR number
and an offset, and the RC rings the doorbell with a single DWORD MMIO
write.

Some doorbell backends may report that the doorbell target is already
exposed via a platform-owned fixed BAR (db_msg[0].bar/offset). In that
case, reuse the pre-exposed window and do not reprogram the BAR with
pci_epc_set_bar().

Also honor db_msg[0].irq_flags when requesting the doorbell IRQ, and
only restore the original BAR mapping on disable if pci-epf-test
programmed it.

Subject: [PATCH 0438/5214] PCI: endpoint: pci-ep-msi: Add embedded doorbell
 fallback

Some endpoint platforms cannot use platform MSI / GIC ITS to implement
EP-side doorbells. In those cases, EPF drivers cannot provide an
interrupt-driven doorbell and often fall back to polling.

Add an "embedded" doorbell backend that uses a controller-integrated
doorbell target (e.g. DesignWare integrated eDMA interrupt-emulation
doorbell).

The backend locates the doorbell register and a corresponding Linux IRQ
via the EPC aux-resource API. If the doorbell register is already
exposed via a fixed BAR mapping, provide BAR+offset. Otherwise provide
the DMA address returned by dma_map_resource() (which may be an IOVA
when an IOMMU is enabled) so EPF drivers can map it into BAR space.

When MSI doorbell allocation fails with -ENODEV,
pci_epf_alloc_doorbell() falls back to this embedded backend.

Subject: [PATCH 0439/5214] Input: tsc2007 - reduce I2C transactions for Z2
 read

The current implementation sends a separate power-down command
after reading the Z2 value, resulting in an extra I2C
transaction per measurement cycle.

The TSC2007 command byte contains a 2-bit power-down mode
selection field. By selecting the power-down state in the Z2
measurement command, the device powers down after the Z2 A/D
conversion completes, eliminating the subsequent power-down
transaction.

This reduces the number of I2C transactions by one per touch
measurement cycle, decreasing I2C bus overhead and improving
touch sampling performance.

Subject: [PATCH 0442/5214] scsi: ufs: core: Add support to retrieve and store
 TX Equalization settings

Add support for UFS v5.0 JEDEC attributes qTxEQGnSettings and
wTxEQGnSettingsExt to enable persistent storage and retrieval of
optimal TX Equalization settings.

This provides a fast-path for TX Equalization by reusing previously
stored optimal settings, avoiding TX Equalization Training (EQTR)
procedures during subsequent Power Mode changes.

When no valid TX Equalization settings are found, fall back to full TX
EQTR procedures and optionally save the results for future use.

The validity of one set of TX Equalization settings is indicated by
Bit[15] in wTxEQGnSettingsExt.

Subject: [PATCH 0443/5214] pinctrl: sunxi: fix regulator leak in
 sunxi_pmx_request() error path

In the error path of sunxi_pmx_request(), the code calls
regulator_put(s_reg->regulator) to release the regulator. However,
s_reg->regulator is only assigned after a successful regulator_enable().
This causes a memory leak: the regulator obtained via regulator_get()
is never properly released when regulator_enable() fails.

Fixes: dc1445584177 ("pinctrl: sunxi: Fix and simplify pin bank regulator handling")

Subject: [PATCH 0446/5214] media: mgb4: Fix DV timings limits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Provide the real DV timings limits in VIDIOC_DV_TIMINGS_CAP. For the
outputs the pixelclock is limited by the CMT table <25000kHz, 2*94642kHz>,
for the inputs a slightly broader range is possible. The minimal
supported/tested resolution is 64px.

Subject: [PATCH 0449/5214] media: cec: seco: unregister adapter on IR probe
 failure

If secocec_ir_probe() fails after cec_register_adapter() succeeds,
probe returns an error and the driver remove callback is not called.
The current unwind path unregisters the notifier and then falls through
to cec_delete_adapter(), which violates the CEC adapter lifetime rules
after a successful registration.

Add a registered-adapter unwind path that unregisters the notifier and
the adapter instead.

 lane bonding isn't possible

This happens when firmware connection manager is being used. It will
deal with disabling the lane 1 adapter after the tunnel has been
established and re-enabling it afterwards. For this reason only do this
when we know that lane bonding is possible (e.g running software
connection manager).

scheduled tb_handle_hotplug() to run. Avoid possible UAF in this case by
taking the domain reference before scheduling the hotplug handler in
tb_queue_hotplug().

Subject: [PATCH 0456/5214] thunderbolt: Wait for tb_domain_release() to
 complete when driver is removed

We should not call nhi_shutdown() before the domain structure and the
control channel rings are completely released. Otherwise we might
release resources like the nhi->msix_ida that are still referenced in
tb_domain_release(). For this reason wait for the tb_domain_release() to
be completed before continuing to nhi_shutdown() and eventually
releasing of the rest of the data structures.

Subject: [PATCH 0458/5214] thunderbolt: dma_test: No need to store debugfs
 directory pointer

We don't actually need to store the debugfs directory pointer inside
struct dma_test. Instead we can use the debugfs_lookup_and_remove()
which also handles the case if the debugfs directory is already removed
by the core driver (for example when cable is disconnected).

Subject: [PATCH 0459/5214] thunderbolt: Remove service debugfs entries during
 unregister

We add them as part of the register path so to keep it symmetric remove
them as part of the unregister path. This also removes them even if the
service itself is not yet released (but is unregistered), thus allowing
new register with the same service name to happen.

Subject: [PATCH 0460/5214] thunderbolt: Remove XDomain from the bus without
 holding tb->lock

Currently we call device_unregister() for services and the XDomain
itself with tb->lock held. This prevents the service drivers from
calling any functions that may take it. For this reason separate
removing the XDomain from the topology data structures (where we need
the lock) from unregistering the device from the bus (where remove
callbacks of the drivers are being called).

Subject: [PATCH 0461/5214] thunderbolt: Don't create multiple DMA tunnels on
 firmware connection manager

Firmware connection manager supports only one DMA tunnel per XDomain
connection. Firmware prior Intel Titan Ridge failed the operation
directly but the same does not happen anymore on Titan Ridge and
forward. For this reason add an explicit check, and fail the operation
accordingly in the driver.

The I²C device id table is necessary as the device may be, besides through
system firmware, also instantiated in the IPU bridge so matching takes
place using the I²C device id table. Add back the table, with ids for all
supported devices.

Subject: [PATCH 0463/5214] staging: media: ipu7: fix double-free and
 use-after-free in error paths

In both ipu7_isys_init() and ipu7_psys_init(), pdata is allocated and
then passed to ipu7_bus_initialize_device(), which stores it in
adev->pdata. The ipu7_bus_release() function frees adev->pdata when the
device's reference count drops to zero.

Two error paths incorrectly call kfree(pdata) after the device teardown
has already freed it:

1. When ipu7_mmu_init() fails: put_device() is called, which drops the
   reference count to zero and triggers ipu7_bus_release() ->
   kfree(pdata). The subsequent kfree(pdata) is a double-free.

2. When ipu7_bus_add_device() fails: it calls auxiliary_device_uninit()
   internally, which calls put_device() -> ipu7_bus_release() ->
   kfree(pdata). The subsequent kfree(pdata) is again a double-free.

Note that the kfree(pdata) when ipu7_bus_initialize_device() itself
fails is correct, because in that case auxiliary_device_init() failed
and the release function was never set up, so pdata must be freed
manually.

Additionally, the error code was not saved before calling put_device(),
causing ERR_CAST() to dereference the already-freed adev pointer when
constructing the return value. Fix this by saving the error from
dev_err_probe() before put_device() and returning ERR_PTR() instead.

Remove the redundant kfree(pdata) calls and fix the use-after-free in
the return values of the two affected error paths.

Subject: [PATCH 0464/5214] staging: media: ipu7: remove 'U' suffix from
 hexadecimal literals

The ipu7 driver's TODO specifies that the 'U' suffix should be
removed from hexadecimal values in register definitions.

This patch cleans up the definitions in the header files within the
ipu7 directory to comply with the requirements and improve consistency.

The modification was verified by comparing the disassembly of the
built-in.a archive before and after the change. The MD5 hashes of the
disassembly output remained identical, confirming that this is a
purely cosmetic cleanup with no functional impact on the binary.

Subject: [PATCH 0465/5214] media: intel/ipu6: Improve DWC PHY HSFREQRANGE band
 selection for overlapping ranges

The get_hsfreq_by_mbps() function searches the freqranges[] table
backward (from highest to lowest index). Because adjacent frequency
bands overlap, a data rate that falls in the overlap region always
lands on the higher-indexed band.

For data rates up to 1500 Mbps (index 42) every band uses
osc_freq_target 335. Starting at index 43 (1461-1640 Mbps) the
osc_freq_target drops to 208. A sensor running at 1498 Mbps sits in
the overlap between index 42 (1414-1588, osc 335) and index 43
(1461-1640, osc 208). The backward search picks index 43, programming
the lower osc_freq_target of 208 instead of the optimal 335.

This causes DDL lock instability and CSI-2 CRC errors on affected
configurations, such as the OmniVision OV08X40 sensor on Intel Arrow
Lake platforms (Dell Pro Max 16).

Rewrite get_hsfreq_by_mbps() to select the optimal band:

1. Among bands whose min/max range covers the data rate, prefer
   the one with the higher osc_freq_target.
2. If osc_freq_target is equal, prefer the band whose default_mbps
   is closest to the requested rate.

Since the frequency ranges are monotonically increasing, the loop
exits early once min exceeds the requested rate.

For 1498 Mbps this now correctly selects index 42 (osc_freq_target
335, range 1414-1588) instead of index 43 (osc_freq_target 208,
range 1461-1640).

Subject: [PATCH 0467/5214] mux: add devm_mux_state_get_from_np() to get mux
 from child node

Add new API devm_mux_state_get_from_np() to retrieve a mux control from
a specified child device node.

Make devm_mux_state_get() call devm_mux_state_get_from_np() with a NULL
node parameter, which defaults to using the device's own of_node.

Support the following DT schema:

pinctrl@0 {
    uart-func {
            mux-state = <&mux_chip 0>;
    };

    spi-func {
            mux-state = <&mux_chip 1>;
    };
};

Subject: [PATCH 0468/5214] dt-bindings: pinctrl: Add generic pinctrl for
 board-level mux chips
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a generic pinctrl binding for board-level pinmux chips that are
controlled through the multiplexer subsystem.

On some boards, especially development boards, external mux chips are used
to switch SoC signals between different peripherals (e.g. MMC and UART).
The mux select lines are often driven by a GPIO expander over I2C,
as illustrated below:

	┌──────┐      ┌─────┐
	│ SOC  │      │     │    ┌───────┐
	│      │      │     │───►│ MMC   │
	│      │      │ MUX │    └───────┘
	│      ├─────►│     │    ┌───────┐
	│      │      │     │───►│ UART  │
	│      │      └─────┘    └───────┘
	│      │         ▲
	│      │    ┌────┴──────────────┐
	│ I2C  ├───►│ GPIO Expander     │
	└──────┘    └───────────────────┘

Traditionally, gpio-hog is used to configure the onboard mux at boot.
However, the GPIO expander may probe later than consumer devices such as
MMC. As a result, the MUX might not be configured when the peripheral
driver probes, leading to initialization failures or data transfer errors.

Introduce a generic pinctrl binding that models the board-level MUX as a
pin control provider and builds proper device links between the MUX, its
GPIO controller, and peripheral devices. This ensures correct probe
ordering and reliable mux configuration.

The implementation leverages the standard multiplexer subsystem, which
provides broad support for onboard mux controllers and avoids the need for
per-driver custom MUX handling.

Allow pinctrl-* pattern as node name because this pinctrl device have not
reg property.

Subject: [PATCH 0469/5214] pinctrl: extract pinctrl_generic_to_map() from
 pinctrl_generic_pins_function_dt_node_to_map()

Refactor pinctrl_generic_pins_function_dt_subnode_to_map() by separating DT
parsing logic from map creation. Introduce a new helper
pinctrl_generic_to_map() to handle mapping to kernel data structures, while
keeping DT property parsing in the subnode function.

Improve code structure and enables easier reuse for platforms using
different DT properties (e.g. pinmux) without modifying the
dt_node_to_map-style callback API. Avoid unnecessary coupling to
pinctrl_generic_pins_function_dt_node_to_map(), which provides
functionality not needed when the phandle target is unambiguous.

Maximize code reuse and provide a cleaner extension point for future
pinctrl drivers.

Subject: [PATCH 0470/5214] pinctrl: add optional .release_mux() callback

Add an optional .release_mux() callback to struct pinmux_ops.

Some drivers acquire additional resources in .set_mux(), such as software
locks. These resources may need to be released when the mux function is no
longer active. Introducing a dedicated .release_mux() callback allows
drivers to clean up such resources.

The callback is optional and does not affect existing drivers.

Commit 2243a87d90b42 ("pinctrl: avoid duplicated calling
enable_pinmux_setting for a pin") removed the .disable() callback
to resolve two issues:

  1. desc->mux_usecount increasing monotonically
  2. Hardware glitches caused by repeated .disable()/.enable() calls

Adding .release_mux() does not reintroduce those problems. The callback is
intended only for releasing driver-side resources (e.g. locks) and must not
modify hardware registers.

Subject: [PATCH 0471/5214] pinctrl: add generic board-level pinctrl driver
 using mux framework

Many boards use on-board mux chips (often controlled by GPIOs from an I2C
expander) to switch shared signals between peripherals.

Add a generic pinctrl driver built on top of the mux framework to
centralize mux handling and avoid probe ordering issues. Keep board-level
routing out of individual drivers and supports boot-time only mux
selection.

Ensure correct probe ordering, especially when the GPIO expander is probed
later.

Subject: [PATCH 0472/5214] clk: microchip: rename clk-core to clk-pic32

clk-core is a confusingly generic name, since it is only used by a
single platform and it uses very similar naming to the "soft" IP cores
for use in FPGA fabric (CoreClock or similar is what that would be
called, although nothing like that exists right now) that the FPGA
business unit produces. Rename it to clk-pic32, matching the prefix
used by most functions in the driver. As far as I can tell, impact
on whatever users may (or may not...) exist for the platform is minimal
as it's built-in only and the functions are called directly from
clk-pic32mzda.c

Subject: [PATCH 0473/5214] media: vidtv: fix NULL pointer dereference in
 vidtv_mux_push_si

syzbot reported a general protection fault in
vidtv_psi_ts_psi_write_into [1].

vidtv_mux_get_pid_ctx() can return NULL, but vidtv_mux_push_si() does
not check for this before dereferencing the returned pointer to access
the continuity counter. This leads to a general protection fault when
accessing a near-NULL address.

The root cause is that vidtv_mux_pid_ctx_init() does not check the
return value of vidtv_mux_create_pid_ctx_once() for PMT section PIDs.
If the allocation fails, the PID context is never created, but init
returns success. The subsequent vidtv_mux_push_si() call then gets
NULL from vidtv_mux_get_pid_ctx() and crashes.

Fix both the root cause (add error check in vidtv_mux_pid_ctx_init
for PMT PIDs) and add defensive NULL checks in vidtv_mux_push_si for
all vidtv_mux_get_pid_ctx() calls.

Subject: [PATCH 0474/5214] media: ti: vpe: Fix fwnode_handle leak in
 vip_probe_complete()

In vip_probe_complete(), the fwnode_handle reference is not released
if the loop continues via the default switch case or if alloc_port()
fails. This results in a reference count leak.

Switch to using the __free(fwnode_handle) cleanup attribute to ensure
the reference is automatically released when the handle goes out of
scope.

Subject: [PATCH 0480/5214] media: aspeed: fix missing
 of_reserved_mem_device_release() on probe failure

aspeed_video_init() calls of_reserved_mem_device_init() to associate
reserved memory regions with the device. When aspeed_video_setup_video()
subsequently fails in aspeed_video_probe(), the error path frees the
JPEG buffer and unprepares the clocks but does not release the reserved
memory association, leaking the rmem_assigned_device entry on the global
list.

The normal remove path already calls of_reserved_mem_device_release()
correctly; only the probe error path was missing it.

Add the missing of_reserved_mem_device_release() call to the
aspeed_video_setup_video() failure cleanup.

Subject: [PATCH 0481/5214] staging: media: av7110: fix coding style

Fix indentation and alignment issues reported by checkpatch.pl.

Rename enums av7110_rec_play_state, av7110_type_rec_play_format,
and av7110_encoder_command to follow kernel naming style.

Rename wssData and wssMode to wss_data and wss_mode to avoid
camelCase identifiers.

Subject: [PATCH 0482/5214] media: nuvoton: npcm-video: fix error handling in
 npcm_video_init()

npcm_video_init() has two error handling issues after
of_reserved_mem_device_init() is called:

When dma_set_mask_and_coherent() fails, the function releases the
reserved memory but does not return, allowing execution to fall through
into npcm_video_ece_init() with a failed DMA configuration.

When npcm_video_ece_init() fails, the function returns an error without
calling of_reserved_mem_device_release(), leaking the reserved memory
association.

Fix both by adding the missing return after the DMA mask failure and
adding the missing of_reserved_mem_device_release() call on the ECE init
error path.

Subject: [PATCH 0483/5214] media: nuvoton: npcm-video: fix memory leaks in
 probe and remove

npcm_video_probe() allocates the npcm_video structure with kzalloc_obj()
but never frees it on any probe error path or in npcm_video_remove(),
leaking the allocation on every failed probe and every normal unbind.

Additionally, when npcm_video_setup_video() fails, the reserved memory
association established by of_reserved_mem_device_init() in
npcm_video_init() is not released, leaking the rmem_assigned_device
entry on the global list.

Fix both by adding kfree(video) to all probe error paths and to
npcm_video_remove(), and adding the missing
of_reserved_mem_device_release() call when npcm_video_setup_video()
fails.

The same kconfig 'select FONT_8x16' appears twice for VIDEO_SOLO6X10.
I propose removing the second instance, as it is effectively dead code.

This dead code was found by kconfirm, a static analysis tool for Kconfig.

 imbalance

The driver reuses the OF node of the parent device but fails to take

when unbinding the parent and releasing the child devices.

Fix this by using the intended helper for reusing OF nodes.

Subject: [PATCH 0491/5214] media: dm1105: fix missing error check for
 dma_alloc_coherent

The return value of dm1105_dma_map(), which handles DMA memory allocation,
is ignored in dm1105_hw_init(). If dma_alloc_coherent() fails, the driver
will proceed using a NULL pointer for DMA transfers, leading to a kernel
oops or invalid hardware access.

Fix this by checking the return value and propagating -ENOMEM on failure.

Subject: [PATCH 0492/5214] media: vidtv: fix reference leak on failed device
 registration

When platform_device_register() fails in vidtv_bridge_init(), the
embedded struct device in vidtv_bridge_dev has already been initialized
by device_initialize(), but the failure path returns the error without
dropping the device reference for the current platform device:

  vidtv_bridge_init()
    -> platform_device_register(&vidtv_bridge_dev)
       -> device_initialize(&vidtv_bridge_dev.dev)
       -> setup_pdev_dma_masks(&vidtv_bridge_dev)
       -> platform_device_add(&vidtv_bridge_dev)

This leads to a reference leak when platform_device_register() fails.
Fix this by calling platform_device_put() before returning the error.

The issue was identified by a static analysis tool I developed and
confirmed by manual review.

Subject: [PATCH 0494/5214] media: vivid: fix cleanup bugs in vivid_init()

When platform_device_register() fails in vivid_init(), the embedded
struct device in vivid_pdev has already been initialized by
device_initialize(), but the failure path jumps to free_output_strings
without dropping the device reference for the current platform device:

  vivid_init()
    -> platform_device_register(&vivid_pdev)
       -> device_initialize(&vivid_pdev.dev)
       -> setup_pdev_dma_masks(&vivid_pdev)
       -> platform_device_add(&vivid_pdev)

This leads to a reference leak when platform_device_register() fails.
Fix this by calling platform_device_put() before jumping to the common
cleanup path.

Also, the unreg_driver label incorrectly calls
platform_driver_register() instead of platform_driver_unregister(),
which breaks cleanup when workqueue creation fails after successful
driver registration. Fix that as well.

The reference leak was identified by a static analysis tool I developed
and confirmed by manual review. The incorrect cleanup call was found
during code inspection.

Subject: [PATCH 0495/5214] media: marvell-cam: fix missing
 pci_disable_device() on remove

During manual code audit, we found that cafe_pci_probe() enables the
PCI device with pci_enable_device(), and its probe error path properly
calls pci_disable_device() on failure.

However, cafe_pci_remove() tears down the controller and frees the
driver data without disabling the PCI device, leaving the remove path
inconsistent with probe cleanup.

Add the missing pci_disable_device() call to cafe_pci_remove().

If the vpe_top resource is missing, vpe_probe() returns -ENODEV after

Subject: [PATCH 0500/5214] media: i2c: drop unneeded dependencies on OF_GPIO

OF_GPIO is selected automatically on all OF systems. Any symbols it
controls also provide stubs so there's really no reason to select it
explicitly. For Kconfig entries that have no other dependencies: convert
it to requiring OF to avoid new symbols popping up for everyone in make
config, for others just drop it altogether.

Subject: [PATCH 0501/5214] media: stm32: dcmi: unregister notifier on probe
 failure

dcmi_graph_init() registers the async notifier before dcmi_probe() toggles
the reset line. If reset_control_assert() or reset_control_deassert()
fails afterwards, probe returns through err_cleanup and the driver core
will not call dcmi_remove().

Unregister the notifier before cleaning it up on that error path,
matching the successful remove path and the V4L2 async notifier lifetime
rules.

Subject: [PATCH 0504/5214] perf dwarf-aux: Fix libdw segmentation fault in
 cu_walk_functions_at

A segmentation fault was observed in `libdw` when running `perf kmem`
with `--page stat` on some workloads. The crash occurred deep inside
`libdw` (specifically in `dwarf_child` and `dwarf_diename`) when
processing DWARF information.

The root cause was improper error handling of `dwarf_getfuncs` in
`die_find_realfunc` and `die_find_tailfunc`.

`dwarf_getfuncs` returns:
 - `0` on success (when all functions have been processed).
 - A positive offset if the callback aborts early (e.g., via
   `DWARF_CB_ABORT` when a match is found).
 - `-1` on error.

The original code used `if (!dwarf_getfuncs(...)) return NULL;`. On
error (`-1`), `!-1` evaluates to `0` (false), bypassing the error
check. Execution then proceeded as if a match was found, returning
uninitialized stack memory (`die_mem`) to the caller
(`cu_walk_functions_at`). When `cu_walk_functions_at` passed this
uninitialized memory to `libdw` via `dwarf_diename`, it caused a
segmentation fault.

Fix this by correcting the error check to `if (dwarf_getfuncs(...) <= 0)`.

Fixes: d4c537e6bf86 ("perf probe: Ignore tail calls to probed functions")

Subject: [PATCH 0505/5214] perf dwarf-aux: Fix libdw API contract violations

Check return values of `dwarf_decl_line` (where non-optional),
`dwarf_getfuncs`, and `dwarf_lineaddr` to prevent using uninitialized
stack variables or incorrectly reporting success on failure.

For the root DIE in `die_walk_lines()`, `dwarf_decl_line` and
`die_get_decl_file` are optional and their failures are handled
gracefully to avoid breaking line walking on valid functions.
Specifically, remove the strict `!decf` (declared file) check that
would prematurely abort line walking on generated or artificial
functions lacking this optional attribute.

Additionally:
 - Add NULL pointer protection for `strcmp()` in `die_walk_lines()`
   when `inf` or `decf` are NULL to prevent crashes on generated
   code.
 - Use `dwarf_attr_integrate` in `die_get_data_member_location` to
   correctly resolve inherited member locations (e.g. via abstract
   origin or specification).

This ensures inline callchains are not corrupted when nest depth > 2.

Subject: [PATCH 0509/5214] perf libdw: Fix libdw API contract violations and
 memory leaks

Check return values of `dwfl_report_end` and `dwfl_module_addrdie`
to prevent using uninitialized stack variables or reporting success on
failure.

Additionally:
 - Ensure `*file` is freed and inline frames are cleared on error in
   `libdw__addr2line()` to prevent memory leaks and duplicated
   callchains when falling back to other unwinders.
 - Use `die_name()` safe wrapper inside the inline function unwinding
   callback (`libdw_a2l_cb`).
 - Refactor `libdw_a2l_cb`'s repeated memory error handling/cleanup
   paths using a cleaner goto control flow.

Subject: [PATCH 0510/5214] perf probe-finder: Fix libdw API contract
 violations

Check return values of `dwarf_formsdata`, `dwarf_entrypc`,
`dwarf_highpc`, `dwarf_bytesize`, `dwarf_attr`, `dwarf_decl_line`,
`dwarf_getfuncs`, and `dwarf_formref_die`. Validate `dwarf_diename` and
`dwarf_diecu` results to prevent potential crashes. Fix C90 mixed
declarations.

Additionally:
 - Avoid vfprintf undefined behavior with NULL strings by using the
   `die_name()` helper for `dwarf_diename()` in `pr_*` calls,
   including when warning about tail calls.
 - Prevent NULL pointer dereference in `convert_variable_fields()`
   when processing array elements for variables in registers.
 - Fallback to offset 0 in `line_range_search_cb()` instead of
   skipping functions without `DW_AT_decl_line`.
 - Relax `dwarf_getfuncs` error checking in
   `find_probe_point_by_func()` and `find_line_range_by_func()` to
   prevent premature CU search aborts, ensuring robustness against
   corrupted CUs.

Fixes: 66f69b2197167cb9 ("perf probe: Support DW_AT_const_value constant value")
Fixes: 3d918a12a1b3088a ("perf probe: Find fentry mcount fuzzed parameter location")
Fixes: bcfc082150c6b1e9 ("perf probe: Remove redundant dwarf functions")
Fixes: 221d061182b8ff55 ("perf probe: Fix to search local variables in appropriate scope")
Fixes: b55a87ade3839c33 ("perf probe: Remove die() from probe-finder code")
Fixes: 4c859351226c920b ("perf probe: Support glob wildcards for function name")

Subject: [PATCH 0511/5214] perf annotate-data: Fix libdw API contract
 violations

Check return values of `dwarf_aggregate_size` and `dwarf_formudata`.

Additionally:
 - Avoid `vfprintf` undefined behavior with `NULL` strings by using
   the `die_name()` helper for `dwarf_diename()` in `pr_*` calls.
 - Use `die_get_data_member_location()` (updated to use
   `dwarf_attr_integrate`) to correctly parse location expressions
   for inherited member locations in the fallback path when
   `dwarf_formudata()` fails.

Fixes: 2bc3cf575a162a2c ("perf annotate-data: Improve debug message with location info")
Fixes: 4a111cadac85362e ("perf annotate-data: Add member field in the data type")

Subject: [PATCH 0512/5214] perf debuginfo: Fix libdw API contract violations

Check return value of `dwfl_report_end` during offline initialization.
Validate `dwfl_module_relocation_info` result before passing to `strcmp`
to avoid potential segmentation faults.

Additionally:
 - Fix a file descriptor leak in `debuginfo__init_offline_dwarf()` when
   `dwfl_report_offline()` or subsequent setup calls fail.

Subject: [PATCH 0513/5214] perf callchain: Handle multiple address spaces

perf test 'perf inject to convert DWARF callchains to regular ones'
fails on s390. It was introduced with commit 92ea788d2af4e65a ("perf
inject: Add --convert-callchain option")

The failure comes the difference in output. Without the inject script to
convert DWARF the callchains is:

 # perf record -F 999 --call-graph dwarf -- perf test -w noploop
 # perf report -i perf.data --stdio --no-children -q \
					 --percent-limit=1 > /tmp/111
 # cat /tmp/111
    99.30%  perf-noploop  perf               [.] noploop

            ---noploop

               cmd_test
               run_builtin (inlined)
               handle_internal_command

               __libc_start_main_impl (inlined)
               _start
 #

With the inject script step the output is:

 # perf inject -i perf.data --convert-callchain -o /tmp/perf-inject-1.out
 # perf report -i /tmp/perf-inject-1.out --stdio --no-children -q \
		--percent-limit=1 > /tmp/222

 <                __libc_start_main_impl (inlined)
 #

The difference are the symbols __libc_start_call_main and
__libc_start_main_impl.

On x86_64, kernel and user space share a single virtual address space,
with the kernel mapped to the upper end of memory. The instruction
pointer value alone is sufficient to distinguish between user space and
kernel space addresses.

This is not true for s390, which uses separate address spaces for user
and kernel.

The same virtual address can be valid in both address spaces, so the
instruction pointer value alone cannot determine whether an address
belongs to the kernel or user space.

Instead, perf must rely on the cpumode metadata derived from the
processor status word (PSW) at sample time.

In function perf_event__convert_sample_callchain() the first part
copies a kernel callchain and context entries, if any.

It then appends additional entries ignoring the address space
architecture. Taking that into account, the symbols at addresses

   0x3ff970348cb __libc_start_call_main
   0x3ff970349c5 __libc_start_main_impl

(located after the kernel address space on s390) are now included.

Output before:

 # perf test 83
 83: perf inject to convert DWARF callchains to regular ones : FAILED!

Output after:
 # perf test 83
 83: perf inject to convert DWARF callchains to regular ones : Ok

Question to Namhyung:

In function perf_event__convert_sample_callchain() just before the
for() loop this patch modifies, the kernel callchain is copied,
see this comment and the next 5 lines:

   /* copy kernel callchain and context entries */

Then why is machine__kernel_ip() needed in the for() loop, when
the kernel entries have been copied just before the loop?

Note: This patch was tested on x86_64 virtual machine and succeeded.

Don't call strtol() with a null pointer to avoid undefined behavior.

I'm not sure of the exact scenario for missing CPU IDs but I don't think
it happens in practice. SPE decoding can continue without them with
reduced functionality, but print an error message anyway.

Subject: [PATCH 0516/5214] perf arm_spe: Store MIDR in arm_spe_pkt

The MIDR will affect printing of arm_spe_pkts, so store a copy of it
there. Technically it's constant for each decoder, but there is no
decoder when doing a raw dump, so it has to be stored in every packet.
It will only be used in raw dump mode and not in normal decoding for
now, but to avoid any surprises, set MIDR properly on the decoder too.

Having both the MIDR and the arm_spe_pkt (which has a copy of it) in the
decoder seemed a bit weird, so remove arm_spe_pkt from the decoder. The
packet is only short lived anyway so probably shouldn't have been there
in the first place.

Subject: [PATCH 0517/5214] perf arm_spe: Turn event name mappings into an
 array

This is so we can have a single function that prints events and can be
used with multiple mappings from different CPUs. Remove any bit that was
printed so that later we can print out the remaining unknown impdef
bits.

No functional changes intended.

Subject: [PATCH 0518/5214] perf arm_spe: Decode Arm N1 IMPDEF events

>From the TRM [1], N1 has one IMPDEF event which isn't covered by the
common list. Add a framework so that more cores can be added in the
future and that the N1 IMPDEF event can be decoded. Also increase the
size of the buffer because we're adding more strings and if it gets
truncated it falls back to a hex dump only.

Any IMPDEF events not printed out from a known core's IMPDEF list or for

by printing the remaining bits as comma separated raw numbers, e.g.
"IMPDEF:1,2,3,4".

Subject: [PATCH 0522/5214] perf build: Remove NO_GTK2 build test

4751bddd3f983af2 ("perf tools: Make GTK2 support opt-in") changed GTK2
build to be opt-in.

So NO_GTK2 is meaningless and we need to pass GTK2=1 to enable it.
Let's update the build-test configuration for that.

Also make_no_ui is the same as make_no_slang since NO_GTK2 is no-op.

Let's get rid of it as well.

Subject: [PATCH 0523/5214] media: vb2: use ssize_t for vb2_read/vb2_write

vb2_read() and vb2_write() return size_t, but propagate
negative errno values from __vb2_perform_fileio().

This relies on implicit signed/unsigned conversions in callers
(e.g. vb2_fop_read()) to recover error codes:

    __vb2_perform_fileio() -> -EINVAL
    vb2_read()             -> (size_t)-EINVAL
    vb2_fop_read()         -> -EINVAL

This relies on implicit conversions that are not obvious.

These helpers are exported (EXPORT_SYMBOL_GPL) and part of the
vb2 API, so changing their return type may affect existing users.

However, they conceptually follow read/write semantics, where
ssize_t is typically used to return either a byte count or a
negative error code.

Switch vb2_read() and vb2_write() to ssize_t, and update
__vb2_perform_fileio() accordingly.

Add a check for the return value of pci_ioremap_bar()
in cx23885_dev_setup().
If ioremap for BAR0 fails, release the already allocated
PCI memory region,
decrement the device count, and return -ENODEV.

This prevents a potential null pointer dereference and
ensures proper cleanup
on memory mapping failure.

Subject: [PATCH 0525/5214] media: cx231xx: fix devres lifetime

USB drivers bind to USB interfaces and any device managed resources
should have their lifetime tied to the interface rather than parent USB
device. This avoids issues like memory leaks when drivers are unbound
without their devices being physically disconnected (e.g. on probe
deferral or configuration changes).

Fix the driver state lifetime so that it is released on driver unbind.

Subject: [PATCH 0526/5214] media: saa7134: Fix a possible memory leak in
 saa7134_video_init1

In saa7134_video_init1(), the return value of the first
saa7134_pgtable_alloc() is not checked. If it fails, the function
continues as if successful, leaving the driver with an invalid page
table. Additionally, if vb2_queue_init() for the VBI queue fails after
the video queue page table has been allocated, the allocated memory is
not freed before returning. The second saa7134_pgtable_alloc() also
lacks a return value check. Errors occur during device probing before
the device is fully registered, the normal cleanup path in
saa7134_finidev() is not executed, leading to memory leaks and
potential use of uninitialized DMA resources.

Check the return value of both saa7134_pgtable_alloc() calls and
propagate errors. On failure of any later step, free allocated page
tables to avoid memory leaks. Ensure control handlers are also
released on error to prevent further resource leakage.

Found by code review.

Subject: [PATCH 0529/5214] media: rtl2832: fix use-after-free in
 rtl2832_remove()

cancel_delayed_work_sync() is called before i2c_mux_del_adapters()
in rtl2832_remove(). While the cancel waits for any running instance
of i2c_gate_work to finish, it does not prevent the timer from being
rescheduled by a concurrent thread.

During probe, the r820t_attach() call attempts I2C transfers through
the mux adapter. These transfers go through i2c_mux_master_xfer(),
which calls rtl2832_deselect() after the transfer completes,
rescheduling i2c_gate_work via schedule_delayed_work(). If this
transfer is still in flight when rtl2832_remove() runs,
rtl2832_deselect() can reschedule i2c_gate_work after it has been
cancelled, causing a use-after-free when kfree(dev) is called.

Fix this by calling i2c_mux_del_adapters() before
cancel_delayed_work_sync(). Once the mux adapter is unregistered, no
new I2C transfers can go through it, so rtl2832_deselect() can no
longer reschedule i2c_gate_work. The subsequent
cancel_delayed_work_sync() is then guaranteed to be final.

Subject: [PATCH 0530/5214] media: tegra-vde: Add HAS_IOMEM dependency to match
 SRAM select

kconfiglint reports:

  K002: config VIDEO_TEGRA_VDE selects visible symbol SRAM which has
        dependencies

VIDEO_TEGRA_VDE selects SRAM, which is defined in drivers/misc/Kconfig as:

  config SRAM
      bool "Generic on-chip SRAM driver"
      depends on HAS_IOMEM

The NVIDIA Tegra video decoder driver was originally introduced in
commit cd6c56feb591 ("media: staging: media: Introduce NVIDIA Tegra video
decoder driver") as a staging driver with
`depends on ARCH_TEGRA || COMPILE_TEST` and
`select SRAM`. Since all Tegra SoCs have HAS_IOMEM, the SRAM dependency was
implicitly satisfied for real hardware configurations.

The driver was later de-staged in commit 8bd4aaf438e3 ("media: staging:
tegra-vde: De-stage driver") and relocated to
drivers/media/platform/nvidia/tegra-vde/ in commit 9b18ef7c9ff4 ("media:
platform: rename tegra/vde/ to nvidia/tegra-vde/"). Throughout these moves,
the `select SRAM` remained without a corresponding HAS_IOMEM dependency.

Under COMPILE_TEST on a hypothetical architecture without HAS_IOMEM (such
as UML in some configurations), the select would force SRAM on without its
HAS_IOMEM dependency being met. Add an explicit `depends on HAS_IOMEM` to
make the dependency chain complete and prevent this misconfiguration under
COMPILE_TEST.

If CONFIG_MEDIA_CONTROLLER is undefined, media_request_object_find() will
always return NULL, so its 2nd call in v4l2_ctrl_request_complete() would
fail as well as the 1st one and thus cause hdl to have a wrong value (at
the top of memory) and list_for_each_entry() to iterate over the garbage
data located there. Add NULL check for the 2nd call and place the error
cleanup at the end of v4l2_ctrl_request_complete()...

Subject: [PATCH 0533/5214] coresight: cti: Fix DT filter signals silently
 ignored

In cti_plat_process_filter_sigs(), after allocating a temporary
cti_trig_grp struct via kzalloc_obj(), the code never assigns tg->nr_sigs
= nr_filter_sigs. Since kzalloc zero-initialises the struct, tg->nr_sigs
remains 0. cti_plat_read_trig_group() guards with:
    if (!tgrp->nr_sigs)
        return 0;

so it returns immediately without reading any signal indices from DT.

Fix by assigning tg->nr_sigs before calling cti_plat_read_trig_group().

The "instance" word has a specific meaning in TPMI. It is a physical
index related to compute dies and IO dies present on a single TPMI
partition (which is also a single TPMI device). It's used for mapping
MMIO blocks for direct TPMI register access.

The currently used "instance_id" uncore_data struct field is a
sequentially generated value that's used for appending to uncore
directories inside the /sys/devices/system/cpu/intel_uncore_frequency
directory. It has no relation to the physical TPMI elements.

 in the sysfs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Insufficient data is exported to allow direct access to TPMI registers
through MMIO. On non-partitioned systems domain_id can be used both for
mapping CPUs to their compute die IDs and for mapping die indices to
their MMIO memory blocks presented to userspace via TPMI debugfs.
However on partitioned systems the debugfs association doesn't work
anymore. This is due to how TPMI partitioning influences domain_id
calculation. The previous association is lost on partitioned systems in
order to keep using domain_id for mapping CPUs to compute dies.

Expose the instance ID in sysfs that's unique in the scope of one TPMI
partition (and hence one TPMI device). It's a physical index into mapped
MMIO blocks and can be used by userspace to figure out how to directly
access TPMI registers.

Subject: [PATCH 0538/5214] media: platform: amd: low level support for isp4
 firmware

Low level functions for accessing the registers and mapping to their
ranges. This change also includes register definitions for ring buffer
used to communicate with ISP Firmware. Ring buffer is the communication
interface between driver and ISP Firmware. Command and responses are
exchanged through the ring buffer.

Subject: [PATCH 0539/5214] media: platform: amd: Add isp4 fw and hw interface

ISP firmware controls ISP HW pipeline using dedicated embedded processor
called ccpu. The communication between ISP FW and driver is using commands
and response messages sent through the ring buffer. Command buffers support
either global setting that is not specific to the stream and support stream
specific parameters. Response buffers contain ISP FW notification
information such as frame buffer done and command done. IRQ is used for
receiving response buffer from ISP firmware, which is handled in the main
isp4 media device. ISP ccpu is booted up through the firmware loading
helper function prior to stream start. Memory used for command buffer and
response buffer needs to be allocated from amdgpu buffer manager because
isp4 is a child device of amdgpu.

Subject: [PATCH 0540/5214] media: platform: amd: isp4 subdev and firmware
 loading handling added

Isp4 sub-device is implementing v4l2 sub-device interface. It has one
capture video node, and supports only preview stream. It manages firmware
states, stream configuration. Add interrupt handling and notification for
isp firmware to isp-subdevice.

Subject: [PATCH 0541/5214] media: platform: amd: isp4 video node and buffers
 handling added

Isp video implements v4l2 video interface and supports NV12 and YUYV. It
manages buffers, pipeline power and state. Cherry-picked Sultan's DMA
buffer related fix from branch v6.16-drm-tip-isp4-for-amd on
https://github.com/kerneltoast/kernel_x86_laptop.git

+====================================
+AMD Image Signal Processor (amdisp4)
+====================================
+
+Introduction
+============
+
+This file documents the driver for the AMD ISP4 that is part of
+AMD Ryzen AI Max 300 Series.
+
+The driver is located under drivers/media/platform/amd/isp4 and uses
+the Media-Controller API.
+
+The driver exposes one video capture device to userspace and provide
+web camera like interface. Internally the video device is connected
+to the isp4 sub-device responsible for communication with the CCPU FW.
+
+Topology
+========
+
+.. _amdisp4_topology_graph:
+
+.. kernel-figure:: amdisp4.dot
+     :alt:   Diagram of the media pipeline topology
+     :align: center
+
+
+
+The driver has 1 sub-device: Representing isp4 image signal processor.
+The driver has 1 video device: Capture device for retrieving images.
+
+- ISP4 Image Signal Processing Subdevice Node
+
+---------------------------------------------
+
+The isp4 is represented as a single V4L2 subdev, the sub-device does not
+provide interface to the user space. The sub-device is connected to one video node
+(isp4_capture) with immutable active link. The sub-device represents ISP with
+connected sensor similar to smart cameras (sensors with integrated ISP).
+sub-device has only one link to the video device for capturing the frames.
+The sub-device communicates with CCPU FW for streaming configuration and
+buffer management.

+- isp4_capture - Frames Capture Video Node
+
+------------------------------------------
+
+Isp4_capture is a capture device to capture frames to memory.
+The entity is connected to isp4 sub-device. The video device
+provides web camera like interface to userspace. It supports
+mmap and dma buf types of memory.

Subject: [PATCH 0544/5214] PCI: amd-mdb: Use the right GPIO header

The driver includes the legacy GPIO header <linux/gpio.h> but does not use
any symbols from it and actually wants <linux/gpio/consumer.h>, so fix this
up.

While Ingenic is a 32-bit platform, it is still better to use the

Subject: [PATCH 0558/5214] dt-bindings: pinctrl: qcom: move gpio-hog schema to
 tlmm-common

Qualcomm TLMM-based pin controllers share the same gpio-hog binding
semantics across multiple SoCs. The gpio-hog pattern currently defined in
qcom,ipq4019-pinctrl.yaml and qcom,sdm845-pinctrl.yaml are not SOC specific
and applies to all TLMM controllers.

Move the gpio-hog patternProperties definition to qcom,tlmm-common.yaml so
that it can be reused by other Qualcomm TLMM pinctrl bindings and avoid
schema duplication.

Subject: [PATCH 0559/5214] pinctrl: qcom: Move MODULE_DEVICE_TABLE next to the
 table itself

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it
exports, because this is easier to read and verify.  It also makes more
sense since #ifdef for ACPI or OF could hide both of them.

Some Qualcomm pin controller drivers already have this correctly placed,
so adjust the other drivers.  No functional impact.

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it
exports, because this is easier to read and verify.  It also makes more
sense since #ifdef for ACPI or OF could hide both of them.

Most of the pin controller drivers already have this correctly placed,
so adjust the other drivers.  No functional impact.

Subject: [PATCH 0562/5214] pinctrl: qcom: Make important drivers default (1)

The main SoC TLMM (Top-Level Multiplexer) pin controller drivers are
essential for booting up SoCs and are not really optional for a given
platform.  Kernel should not ask users choice of drivers when that
choice is obvious and known to the developers that answer should be
'yes' or 'module'.

Switch all Qualcomm TLMM pin controller drivers to a default 'yes' for
ARCH_QCOM.  This has impact:

1. arm64 defconfig: enable PINCTRL_SM7150, PINCTRL_IPQ9650 and
   PINCTRL_HAWI, which were not selected before but should be, because
   these platforms need them for proper boot.

2. arm qcom_defconfig: no changes.

3. arm multi_v7 defconfig: enable drivers necessary to boot ARM 32-bit
   platforms, which are already enabled on qcom_defconfig.

4. COMPILE_TEST builds: enable by default all drivers for arm or arm64
   builds, whenever ARCH_QCOM is selected.  This has impact on build
   time and feels logical, because if one selects ARCH_QCOM then
   probably by default wants to build test it entirely.  Kernels with
   COMPILE_TEST are not supposed to be used for booting.

Subject: [PATCH 0563/5214] PCI: Always lift 2.5GT/s restriction in PCIe failed
 link retraining

Discard Vendor:Device ID matching in the PCIe failed link retraining quirk
and ignore the link status for the removal of the 2.5GT/s speed clamp,
whether applied by the quirk itself or the firmware earlier on.  Revert to
the original target link speed if this final link retraining has failed.

This is so that link training noise in hot-plug scenarios does not make a
link remain clamped to the 2.5GT/s speed where an event race has led the
quirk to apply the speed clamp for one device, only to leave it in place
for a subsequent device to be plugged in.

Refer to the Link Capabilities register directly for the maximum link speed
determination so as to streamline backporting.

Subject: [PATCH 0565/5214] PCI: Bail out early for 2.5GT/s devices in PCIe
 failed link retraining

There's no point in retraining a failed 2.5GT/s device at 2.5GT/s, so just
don't and return early.  While such devices might be unlikely to implement
Link Active reporting, we need to retrieve the maximum link speed and use
it in a conditional later on anyway, so the early check comes for free.

Subject: [PATCH 0567/5214] soundwire: fix bug in sdw_add_element_group_count
 found by syzkaller

The original implementation caused an out-of-bounds memory access
in the sdw_add_element_group_count for-loop when i == num.

for (i = 0; i <= num; i++) {
    if (rate == group->rates[i] && lane == group->lanes[i])

To fix this error, the function now checks for existing rate/lane
entries in the group(a function parameter) using a for-loop before
adding them.

No functional changes apart from this fix.

Subject: [PATCH 0576/5214] media: imx219: Set horizontal blanking on mode
 change

The driver UAPI is mode-based, allowing the user to choose a mode from a
small list based on the output size. The vertical blanking is set based on
the mode, do the same for horizontal blanking so the frame rate obtained
is constant.

Additionally, it's best to use a known-good horizontal blanking value as
choosing the value freely may affect image quality. While the minimum
value may not be the best value for horizontal blanking, at least it is
constant rather than a minimum value of a different configuration.

Subject: [PATCH 0589/5214] coresight: tmc: Fix overflow when calculating is
 bigger than 2GiB

When specifying a 2GB AUX buffer, the ETR driver ends up allocating only
a 1MB buffer instead:

  # echo 'file coresight-tmc-etr.c +p' > \
	/sys/kernel/debug/dynamic_debug/control
  # perf record -e cs_etm/@tmc_etr0,timestamp=0/u -C 0 -m ,2G -- test
  coresight tmc_etr0: allocated buffer of size 1024KB in mode 0

The page index is an 'int' type, and shifting it by PAGE_SHIFT overflows
when the resulting value exceeds 2GB.  This produces a negative value,
causing the driver to fall back to the minimum buffer size (1MB).

Cast the page index to a wider type to accommodate large buffer sizes.
Also fix a similar issue in the buffer offset calculation.

Subject: [PATCH 0590/5214] coresight: ete: Always save state on power down

System register ETMs and ETE are unlikely to be preserved on CPU power
down. The ETE DT binding also never documented
"arm,coresight-loses-context-with-cpu" so nobody would have legitimately
been able to use that binding to fix it and ACPI has no such binding at
all.

Fix it by hard coding the setting for sysreg ETMs (ETE is always sysreg)
or ACPI boots. Use a local variable when setting up save_state so that
it's immune to concurrent probing when devices have different
configurations which is an issue with modifying the global.

This fixes the following error when using Coresight with ACPI on the FVP
which supports CPU PM:

Subject: [PATCH 0593/5214] PCI/ASPM: Don't reconfigure ASPM entering low-power
 state

Reconfiguring ASPM when a device transitions to low-power state can enable
L1.1/L1.2 substates on the PCIe link at a time when the device is sleeping
and may be unable to exit them. ASPM should be reconfigured on D0 entry
(resume), not on the way down.

pci_set_low_power_state() calls pcie_aspm_pm_state_change() after writing
D3hot to PCI_PM_CTRL. pcie_aspm_pm_state_change() resets link->aspm_capable
to link->aspm_support and then calls pcie_config_aspm_path(), which can
enable ASPM L1.1/L1.2 substates on the PCIe link. If the device cannot
recover the link from L1.2 while in D3hot, subsequent config space reads
return 0xFFFF ("device inaccessible") and pci_power_up() fails with
messages like:

  vfio-pci 0000:5d:00.0: Unable to change power state from D3hot to D0, device inaccessible

This was observed on NVIDIA H100 SXM5 GPUs bound to vfio-pci when Linux
runtime PM suspends them to D3hot: the GPU becomes permanently inaccessible
and disappears from the PCIe bus.

The call to pcie_aspm_pm_state_change() in pci_set_low_power_state() was
restored by f93e71aea6c6 ("Revert "PCI/ASPM: Remove
pcie_aspm_pm_state_change()""), which reverted 08d0cc5f3426 ("PCI/ASPM:
Remove pcie_aspm_pm_state_change()").  The revert was necessary because the
removal broke suspend/resume on certain platforms that required ASPM to be
reconfigured on D0 entry. However, the revert restored the call in both
pci_set_full_power_state() (D0 entry) and pci_set_low_power_state()
(low-power entry).

Only the D0-entry call is needed to fix the suspend/resume regression. The
low-power-entry call is harmful: reconfiguring ASPM immediately after
putting a device into D3hot can enable link substates that the device or
platform cannot exit while the device is sleeping.

Remove the pcie_aspm_pm_state_change() call from pci_set_low_power_state().
ASPM will still be reconfigured correctly when the device returns to D0 via
pci_set_full_power_state().

 to its target GPIO device
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The software node representing the GPIO controller to consumers is
"dangling": it's not really attached to the device. The GPIO lookup
relies on matching the name of the node to the chip's label. Switch to
using platform_device_register_full() and use the swnode field of struct
platform_device_info to attach the software node to the GPIO device.

Subject: [PATCH 0597/5214] platform/x86: x86-android-tablets: enable fwnode
 matching of GPIO chips
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In order to allow GPIOLIB to match cherryview and baytrail GPIO
controllers by their firmware nodes instead of their names, we need to
attach the - currently "dangling" - existing software nodes to their
target devices dynamically.

The driver uses platform_create_bundle() and expects all required
providers to be present before it itself is probed. We know the name of
the device we're waiting for so look them up and assign the appropriate
software node as the secondary firmware node of the underlying ACPI node.

Scheduling fine-grained devres actions allows for proper teardown and
unsetting of the secondary firmware nodes.

Subject: [PATCH 0601/5214] platform/x86/intel/pmc: Use PCI DID for PMC SSRAM
 device discovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update the PMC SSRAM discovery process to identify the device using its
PCI Device ID rather than relying on a fixed PCI bus location. The
enumeration of integrated devices on the PCI bus is no longer guaranteed
to be consistent across CPUs.

On earlier platforms, the IOE and PCH SSRAM devices were hidden from the
BIOS, and the SOC SSRAM device is associated to telemetry regions from all
available SSRAM devices. Starting with Nova Lake, the IOE and PCH SSRAM
devices register their telemetry regions independently, meaning each
telemetry region is now linked to its corresponding SSRAM device. A new
ssram_hidden attribute has been added to the pmc_dev_info structure to
reflect this distinction.

 DMU offsets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Add support for handling different DMU Die C6 offsets across platforms.
The previous implementation assumed a uniform DMU Die C6 offset for all
platforms, which is no longer valid after an upcoming change.

Subject: [PATCH 0603/5214] platform/x86/intel/pmc: Retrieve PMC info only for
 available PMCs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update the Intel PMC Core driver to fetch PMC information only for
available PMCs. Previously, the driver attempted to retrieve PMC info
even when the corresponding PMC was not present.

This change aligns with recent updates to the Intel SSRAM Telemetry
driver. Starting with NVL, the SSRAM Telemetry driver is probed for
each individual SSRAM device. The prior implementation could not
differentiate between an unavailable PMC and one that had not yet
completed information retrieval. To resolve this, the PMC Core driver
now skips obtaining PMC info for unavailable PMCs.

Subject: [PATCH 0606/5214] PCI: Check ROM header and data structure addr
 before accessing

We meet a crash when running stress-ng on x86_64 machine:

  BUG: unable to handle page fault for address: ffa0000007f40000
  RIP: 0010:pci_get_rom_size+0x52/0x220
  Call Trace:
  <TASK>
    pci_map_rom+0x80/0x130
    pci_read_rom+0x4b/0xe0
    kernfs_file_read_iter+0x96/0x180
    vfs_read+0x1b1/0x300

Our analysis reveals that the ROM space's start address is
0xffa0000007f30000, and size is 0x10000. Because of broken ROM space,
before calling readl(pds), the pds's value is 0xffa0000007f3ffff, which is
already pointed to the ROM space end, invoking readl() would read 4 bytes
therefore cause an out-of-bounds access and trigger a crash.  Fix this by
adding image header and data structure checking.

We also found another crash on arm64 machine:

  Unable to handle kernel paging request at virtual address ffff8000dd1393ff
  Mem abort info:
  ESR = 0x0000000096000021
  EC = 0x25: DABT (current EL), IL = 32 bits
  SET = 0, FnV = 0
  EA = 0, S1PTW = 0
  FSC = 0x21: alignment fault

The call trace is the same with x86_64, but the crash reason is that the
data structure addr is not aligned with 4, and arm64 machine report
"alignment fault". Fix this by adding alignment checking.

Subject: [PATCH 0609/5214] PCI/sysfs: Only allow supported resource types in
 I/O and MMIO helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, when the sysfs attributes for PCI resources are added
dynamically, the resource access callbacks are only set when the underlying
BAR type matches, using .read and .write for IORESOURCE_IO, and .mmap for
IORESOURCE_MEM or IORESOURCE_IO with arch_can_pci_mmap_io() support.  As
such, when the callback is not set, the operation inherently fails.

After the conversion to static attributes, visibility callbacks will
control which resource files appear for each BAR, but the callbacks
themselves will always be set.

Add a type check to pci_resource_io() and pci_mmap_resource() to return
-EIO for an unsupported resource type.

Use the new pci_resource_is_io() and pci_resource_is_mem() helpers for the
type checks, replacing the open-coded bitwise flag tests and also drop the
local struct resource pointer in pci_mmap_resource().

Subject: [PATCH 0610/5214] PCI/sysfs: Split pci_llseek_resource() for device
 and legacy attributes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both legacy and resource attributes set .f_mapping = iomem_get_mapping, so
the default generic_file_llseek() would consult iomem_inode for the file
size, which knows nothing about the attribute.  That is why custom llseek
callbacks exist.

Currently, the legacy and resource attributes have .size set at creation
time, as such, using the attr->size is sufficient.  However, the upcoming
static resource attributes will have .size == 0 set, since they are const,
and the .bin_size() callback will be used to provide the real size to
kernfs instead.

The legacy attributes operate on a struct pci_bus, not struct pci_dev, so
calling to_pci_dev() on them would be invalid.

Thus, split pci_llseek_resource() into two functions:

  - pci_llseek_resource(), which derives the file size from the BAR using
    pci_resource_len().

  - pci_llseek_resource_legacy(), which uses attr->size directly.

Update the dynamic legacy attribute creation to use the new
pci_llseek_resource_legacy() callback.

The original pci_llseek_resource() was added in commit 24de09c16f97 ("PCI:
Implement custom llseek for sysfs resource entries").

 __resource_resize_store()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, the __resource_resize_store() allows writing to the
resourceN_resize sysfs attribute to change a BAR's size without checking
for capabilities, currently relying only on the file access check.

Resizing a BAR modifies PCI device configuration and can disrupt active
drivers.  After the upcoming conversion to static attributes, it will also
trigger resource file updates via sysfs_update_groups().

Add a CAP_SYS_ADMIN check to prevent unprivileged users from performing BAR
resize operations.

Subject: [PATCH 0612/5214] PCI/sysfs: Add static PCI resource attribute macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add three macros for declaring static binary attributes for PCI resource
files:

  - pci_dev_resource_io_attr(), for I/O BAR resources (read/write)
  - pci_dev_resource_uc_attr(), for memory BAR resources (mmap uncached)
  - pci_dev_resource_wc_attr(), for write-combine resources (mmap WC)

Each macro only sets the callbacks its resource type needs.  The I/O macro
conditionally includes mmap support via __PCI_RESOURCE_IO_MMAP_ATTRS on
architectures where arch_can_pci_mmap_io() is true at compile time (such as
PowerPC, SPARC, and Xtensa).

Subject: [PATCH 0613/5214] media: uvcvideo: Fix sequence number when no EOF

If the driver could not detect the EOF, the sequence number is increased
twice:
 1) When we enter uvc_video_decode_start() with the old buffer and FID has
   flipped => We return -EAGAIN and last_fid is not flipped
 2) When we enter uvc_video_decode_start() with the new buffer.

Fix this issue by moving the new frame detection logic earlier in
uvc_video_decode_start().

This also has some nice side affects:

- The error status from the new packet will no longer get propagated
  to the previous frame-buffer.
- uvc_video_clock_decode() will no longer update the previous frame
  buf->stf with info from the new packet.
- uvc_video_clock_decode() and uvc_video_stats_decode() will no longer
  get called twice for the same packet.

Subject: [PATCH 0614/5214] media: uvcvideo: Fix buffer sequence in frame gaps

In UVC, the FID flips with every frame. For every FID flip, we increase
the stream sequence number.

Now, if a FID flips multiple times and there is no data transferred between
the flips, the buffer sequence number will be set to the value of the
stream sequence number after the first flip.

Userspace uses the buffer sequence number to determine if there have been
missing frames. With the current behaviour, userspace will think that the
gap is in the wrong location.

This patch modifies uvc_video_decode_start() to provide the correct buffer
sequence number and timestamp.

Subject: [PATCH 0615/5214] media: uvcvideo: Import standard controls from
 uvcdynctrl

The uvcdynctrl tool from libwebcam:
https://sourceforge.net/projects/libwebcam/
maps proprietary controls into v4l2 controls using the UVCIOC_CTRL_MAP
ioctl.

The tool has not been updated for 10+ years now, and there is no reason
for the UVC driver to not do the mapping by itself.

This patch adds the mappings from the uvcdynctrl into the driver. Hopefully
this effort can help in deprecating the UVCIOC_CTRL_MAP ioctl.

Some background about UVCIOC_CTRL_MAP (thanks Laurent for the context):

```
this was envisioned as the base of a vibrant ecosystem where a large
number of vendors would submit XML files that describe their XU control
mappings, at a pace faster than could be supported by adding XU mappings
to the driver. This vision failed to materialize and the tool has not
been updated for 10+ years now. There is no reason to believe the
situation will change.
```

During the porting, the following mappings where NOT imported because
they were not using standard v4l2 IDs. It is recommended that userspace
moves to UVCIOC_CTRL_QUERY for non standard controls.

                .id             = V4L2_CID_FLASH_MODE,

 for UVCIOC_CTRL_MAP

The UVCIOC_CTRL_MAP lets userspace create a mapping for a custom
control.

This mapping is usually created by the uvcdynctrl userspace utility. We
would like to get the mappings into the driver instead.

Subject: [PATCH 0617/5214] media: uvcvideo: Introduce allow_privacy_override
 module parameter

Some camera modules have XU controls that can configure the behaviour of
the privacy LED.

Block mapping of those controls, unless the module is configured with
a new parameter: allow_privacy_override.

Subject: [PATCH 0619/5214] media: qcom: camss: Fix csid clock configuration
 for sa8775p

Fix the mismatch between clock list and clock rate table for CSID lite
instances. The current implementation has 5 clocks defined but only 2
are actually needed (vfe_lite_csid and vfe_lite_cphy_rx), while the
clock rate table doesn't match this configuration.

Update both clock list and rate table to maintain consistency:
- Remove unused clocks: cpas_vfe_lite, vfe_lite_ahb, vfe_lite
- Update clock rate table to match the remaining two clocks

Subject: [PATCH 0621/5214] media: qcom: camss: avoid format string warning

clang-22 warns about csiphy_match_clock_name() taking a variable format
string that is not checked against the 'int index' argument:

drivers/media/platform/qcom/camss/camss-csiphy.c:566:44: error: diagnostic behavior may be improved by
      adding the 'format(printf, 2, 3)' attribute to the declaration of 'csiphy_match_clock_name'
      [-Werror,-Wmissing-format-attribute]
  561 | static bool csiphy_match_clock_name(const char *clock_name, const char *format,
      | __attribute__((format(printf, 2, 3)))
  562 |                                     int index)
  563 | {
  564 |         char name[16]; /* csiphyXXX_timer\0 */
  565 |
  566 |         snprintf(name, sizeof(name), format, index);
      |                                                   ^
drivers/media/platform/qcom/camss/camss-csiphy.c:561:13: note: 'csiphy_match_clock_name' declared here
  561 | static bool csiphy_match_clock_name(const char *clock_name, const char *format,
      |             ^

Change the function to use a snprintf() style format string that allows this
to be checked at the call site.

Subject: [PATCH 0624/5214] media: qcom: camss: Add common TPG support

Introduce a new common Test Pattern Generator (TPG) implementation for
Qualcomm CAMSS. This module provides a generic interface for pattern
generation that can be reused by multiple platforms.

Unlike CSID-integrated TPG, this TPG acts as a standalone block
that emulates both CSIPHY and sensor behavior, enabling flexible test
patterns without external hardware.

Subject: [PATCH 0627/5214] media: qcom: camss: vfe: fix PIX subdev naming on
 VFE lite

VFE lite hardware does not provide a functional PIX path, but after
the per sub-device type resource changes the PIX subdev name is still
assigned unconditionally.

Only assign the PIX subdev name on non-lite VFE variants to avoid
exposing a misleading device name.

Subject: [PATCH 0629/5214] media: qcom: camss: Add debug message to
 camss-video format check

Add a debug trace to video_check_format() to log both the subdev-reported
format and the format requested by the video node. This makes it easier
to diagnose mismatches between subdev output and the negotiated V4L2
pixel format, as well as issues related to plane count, resolution, or
field settings.

Subject: [PATCH 0630/5214] media: qcom: camss: Add per-format BPL alignment
 helper

Add camss_format_get_bpl_alignment(), a helper that returns the
bytes-per-line (BPL) alignment requirement for a given CAMSS format.

Different RAW Bayer packing schemes impose different BPL alignment
constraints (e.g. RAW10 requires multiples of 5 bytes, RAW12 multiples of
3 bytes, RAW14 multiples of 7 bytes, etc.). Centralizing this logic
makes the alignment rules explicit and avoids duplicating them across
the pipeline.

This will allow PIX paths and buffer preparation code to correctly
round up BPL values to hardware-required boundaries.

Subject: [PATCH 0631/5214] media: qcom: camss: Use proper BPL alignment helper
 and non-power-of-two rounding

Bytes-per-line (BPL) alignment in CAMSS currently uses ALIGN(), which
only works correctly for power-of-two values. Some RAW Bayer packing
formats (e.g. RAW10/12/14) require non-power-of-two alignment such as
3, 5, or 7-byte multiples, so ALIGN() produces incorrect results.

Introduce the use of roundup() with the per-format alignment returned by
camss_format_get_bpl_alignment() when no hardware alignment is enforced
(video->bpl_alignment).

Subject: [PATCH 0632/5214] media: qcom: camss: vfe: Make PIX BPL alignment
 format-based on CAMSS_2290

Split the VFE bytes-per-line (BPL) alignment logic into separate
helpers for RDI and PIX paths. RDI is usually aligned on RDI write
engine bus constraint such as 64-bit or 128-bit. But PIX engine
is usually (at least on platform I looked at) based on pixel format.

On CAMSS_2290, PIX BPL alignment is set to 0 to indicate that the
alignment must be derived from the pixel format. This allows the
pipeline to use camss_format_get_bpl_alignment().

For other platforms, retain the legacy PIX default (16 bytes), until
PIX is properly tested/enabled.

A future improvement would be to remove platform-specific conditionals
from the VFE code and move the alignment requirements into the
per-platform VFE resource data.

Subject: [PATCH 0633/5214] media: qcom: camss: Fix RDI streaming for CSID 680

Fix streaming to RDI1 and RDI2. csid->phy.en_vc contains a bitmask of
enabled CSID ports not virtual channels.

We cycle through the number of available CSID ports and test this value
against the vc_en bitmask.

We then use the passed value both as an index to the port configuration
macros and as a virtual channel index.

This is a very broken pattern. Reviewing the initial introduction of VC
support it states that you can only map one CSID to one VFE. This is true
however each CSID has multiple sources which can sink inside of the VFE -
for example there is a "pixel" path for bayer stats which sources @
CSID(x):3 and sinks on VFE(x):pix.

That is CSID port # 3 should drive VFE port #3. With our current setup only
a sensor which drives virtual channel number #3 could possibly enable that
setup.

This is deeply wrong the virtual channel has no relevance to hooking CSID
to VFE, a fact that is proven after this patch is applied allowing
RDI0,RDI1 and RDI2 to function with VC0 whereas before only RDI1 worked.

Another way the current model breaks is the DT field. A sensor driving
different data-types on the same VC would not be able to separate the VC:DT
pair to separate RDI outputs, thus breaking another feature of VCs in the
MIPI data-stream.

Default the VC back to zero. A follow on series will implement subdev
streams to actually enable VCs without breaking CSID source to VFE sink.

Subject: [PATCH 0634/5214] media: qcom: camss: Fix RDI streaming for CSID 340

Fix streaming from CSIDn RDI1 and RDI2 to VFEn RDI1 and RDI2. A pattern we
have replicated throughout CAMSS where we use the VC number to populate
both the VC fields and port fields of the CSID means that in practice only
VC = 0 on CSIDn:RDI0 to VFEn:RDI0 works.

Fix that for CSID 340 by separating VC and port. Fix to VC zero as a bugfix
we will look to properly populate the VC field with follow on patches
later.

Subject: [PATCH 0635/5214] media: qcom: camss: Fix RDI streaming for CSID GEN2

Fix streaming from CSIDn RDI1 and RDI2 to VFEn RDI1 and RDI2. A pattern we
have replicated throughout CAMSS where we use the VC number to populate
both the VC fields and port fields of the CSID means that in practice only
VC = 0 on CSIDn:RDI0 to VFEn:RDI0 works.

Fix that for CSID gen2 by separating VC and port. Fix to VC zero as a
bugfix we will look to properly populate the VC field with follow on
patches later.

Subject: [PATCH 0637/5214] clk: qcom: dispcc-x1e80100: Fix (possibly) dumping
 regmap

Reading few registers at the end of the block (e.g. 0x10000, 0x10004)
might result in synchronous external abort, so limit the regmap to the
last readable register which allows dumping the regs for debugging.

+description: |
+  RPMh interconnect providers support system bandwidth requirements through
+  RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
+  able to communicate with the BCM through the Resource State Coordinator (RSC)
+  associated with each execution environment. Provider nodes must point to at
+  least one RPMh device child node pertaining to their RSC and each provider
+  can map to multiple RPMh resources.

Subject: [PATCH 0642/5214] interconnect: qcom: Add interconnect provider
 driver for Nord SoC

Add driver for the Qualcomm interconnect buses found on Nord SoC.
The topology consists of several NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each
master-slave pair.

Subject: [PATCH 0645/5214] interconnect: Move MODULE_DEVICE_TABLE next to the
 table itself

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it
exports, because this is easier to read and verify.  It also makes more
sense since #ifdef for ACPI or OF could hide both of them.

Most of the privers already have this correctly placed, so adjust
the missing ones.  No functional impact.

 incorrect children if:then: block

This binding has children, so any if:then: block restricting them,
cannot be defined in top-level allOf:if:then:properties:, because it
simply does not match these children.  The block, if it was useful,
should be defined within patternProperties for the children, however
since child nodes do not have clocks at all, there is little point in
disallowing them in the first place.

Remove completely redundant and ineffective piece of code.

On SM8250 most of the video clocks are powered by the MMCX domain, while
the PLL is powered on by the MX domain. Extend the driver to support
scaling both power domains, while keeping compatibility with the
existing DTs, which define only the MX domain.

Subject: [PATCH 0665/5214] media: dt-bindings: qcom,sc7280-venus: drop non-PAS
 support

The only users of the non-PAS setup on SC7280 platform are the ChromeOS
devices, which were cancelled before reaching end users. Iris, the
alternative driver for the same hardware, does not support non-PAS
setup. It is expected that in future both Venus and Iris devices will
use different ABI for non-PAS (EL2) setup.

In order to declare only the future-proof hardware description drop
support for non-PAS setup from the SC7280 Venus schema (breaking almost
non-existing SC7280 ChromeOS devices).

The dropped iommus entry reflects the extra stream, which should not be
treated in the same way as the main one (which doesn't match the usage
described by the iommus definition).

Subject: [PATCH 0666/5214] media: dt-bindings: qcom-sc7180-venus: move
 video-firmware here

As SC7180 is the only remaining user of the non-TZ / non-PAS setup which
uses the video-firmware subnode, move its definition from the common
schema to the SC7180-specific one.

These properties do not accurately describe the hardware.  Future
platforms that are going to support non-TZ setup will use different
semantics and different DT ABI (using the iommu-map property).

With the Iris and Venus driver having more or less feature parity for
"HFI 6xx" platforms and with Iris gaining support for SC7280, flip the
switch. Use Iris by default for SM8250 and SC7280, the platforms which
are supported by both drivers, and use Venus only if Iris is not
compiled at all. Use IS_ENABLED to strip out the code and data
structures which are used by the disabled platforms.

Subject: [PATCH 0668/5214] media: qcom: iris: drop pas_id from the
 iris_platform_data struct

The PAS ID, the authentication service ID, used by the Iris is a
constant and it is not expected to change anytime. Drop it from the
platform data and use the constant instead.

Subject: [PATCH 0669/5214] media: qcom: iris: use common set_preset_registers
 function

The set_preset_registers is (currently) common to all supported devices.
Extract it to a iris_vpu_common.c and call it directly from
iris_vpu_power_on(). Later, if any of the devices requires special
handling, it can be sorted out separately.

Subject: [PATCH 0670/5214] media: qcom: iris: don't use function indirection
 in gen2-specific code

To note that iris_set_num_comv() is gen2-internal, rename it to
iris_hfi_gen2_set_num_comv() and then stop using hfi_ops indirection to
set session property (like other functions in this file do).

Calling HFI instance-specific ops should not require double indirection
through the core ops. Split instance-specific ops to a separate struct,
keep a pointer to it in struct iris_inst and set it directly in the
get_instance function.

Subject: [PATCH 0672/5214] media: qcom: iris: merge hfi_response_ops and
 hfi_command_ops

There is little point in having two different structures for HFI-related
core ops. Merge both of them into the new iris_hfi_ops structure.

Subject: [PATCH 0673/5214] media: qcom: iris: move get_instance to
 iris_hfi_sys_ops

The get_instance() is a callback tightly connected to the HFI
implementation. Move it into the new iris_hfi_sys_ops structure, merging
all core callbacks into a single vtable.

Subject: [PATCH 0674/5214] media: qcom: iris: drop hw_response_timeout_val
 from platform data

The HW response time is a constant between platforms. Remove it from the
iris_platform_data structure and use it directly.

Subject: [PATCH 0675/5214] media: qcom: iris: split firmware_data from raw
 platform data

Having firmware-related fields in platform data results in the tying
platform data to the HFI firmware data rather than the actual hardware.
For example, SM8450 uses Gen2 firmware, so currently its platform data
should be placed next to the other gen2 platforms, although it has the
VPU2.0 core, similar to the one found on SM8250 and SC7280 and so the
hardware-specific platform data is also close to those devices.

Split firmware data to a separate struct, separating hardware-related
data from the firmware interfaces.

Subject: [PATCH 0677/5214] media: qcom: iris: use new firmware name for SM8250

The linux-firmware is providing the vpuNN_pM.mbn firmware for SM8250
since August of 2024. Stop using the legacy firmware name
(vpu-1.0/venus.mbn) and switch to the standard firmware name schema
(vpu/vpu20_p4.mbn).

Subject: [PATCH 0680/5214] interconnect: qcom: Restrict drivers per ARM/ARM64

There is no point to allow selecting core SoC drivers like interconnects
for Qualcomm ARMv7 SoCs when building ARM64 kernel, and vice versa.

This makes kernel configuration more difficult as many do not remember
the Qualcomm SoCs model names/numbers and their properties like
architecture.  No features should be lost because:
1. There won't be a single image for ARMv7 and ARMv8/9 SoCs.
2. Newer ARMv8/9 SoCs won't be running in arm32 emulation mode.

Subject: [PATCH 0687/5214] phy: tegra: xusb: Make USB_CONN_GPIO select
 conditional on GPIOLIB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

kconfiglint reports:

  K006: config PHY_TEGRA_XUSB selects USB_CONN_GPIO which depends on
        GPIOLIB, but PHY_TEGRA_XUSB does not depend on GPIOLIB
  K002: config PHY_TEGRA_XUSB selects visible symbol USB_CONN_GPIO
        which has dependencies

USB_CONN_GPIO was introduced in commit 4602f3bff266 ("usb: common: add USB
GPIO based connection detection driver") with a hard dependency on GPIOLIB,
since it needs GPIO pins to detect USB cable connection state.

Commit f67213cee2b3 ("phy: tegra: xusb: Add usb-role-switch support") added
`select USB_CONN_GPIO` to PHY_TEGRA_XUSB to support USB role switching via
GPIO-based detection. At that time, PHY_TEGRA_XUSB depended only on
`ARCH_TEGRA`, and both the ARM32 and ARM64 ARCH_TEGRA Kconfig definitions
select GPIOLIB, so the missing explicit GPIOLIB guard was not a functional
problem — GPIOLIB is always available when ARCH_TEGRA is enabled.

Later, commit 0d5c9bc7c680 ("phy: tegra: Select USB_COMMON for
usb_get_maximum_speed()") added `depends on USB_SUPPORT` but still did not
address the GPIOLIB gap.

The select can force USB_CONN_GPIO on without its GPIOLIB dependency being
satisfied if the Kconfig dependencies were ever restructured. Make the
select conditional with `select USB_CONN_GPIO if GPIOLIB` to make the
dependency explicit. This mirrors how other drivers handle optional
GPIO-dependent selects throughout the kernel.

Subject: [PATCH 0689/5214] phy: qcom-qmp: Use explicit QSERDES COM v2 register
 definitions

As the code comments in the headers say, both qserdes-com and
qserdes-com-v2 define QSERDES COM registers for QMP V2 PHY.  Switch
phy-qcom-qmp drivers to use register definitions in qserdes-com-v2
to make the QSERDES COM version explicit.

Subject: [PATCH 0690/5214] phy: qcom-qmp-usbc: Use register definitions in
 qserdes-txrx-v3

The register definitions in header qserdes-txrx-v2 and qserdes-txrx-v3
are actually identical.  Considering that QSERDES TX/RX v2 is already
defined by header qserdes-txrx, qserdes-txrx-v2 is really just
a duplication of qserdes-txrx-v3 for QSERDES TX/RX v3.  Switch
qcom-qmp-usbc driver to use v3 registers.

Subject: [PATCH 0691/5214] phy: qcom-qmp-usbc: Rename QCS615 DP PHY variables
 and functions

Commit 81791c45c8e0 ("phy: qcom: qmp-usbc: Add QCS615 USB/DP PHY config
and DP mode support") chose to name  QCS615 DP PHY variables/functions
with qmp_v2 prefix, by assuming that QMP PHY registers are versioned
as a whole.  However, the reality is that the registers are versioned
in sub-modules like QSERDES COM and QSERDES TXRX respectively, e.g.
QCS615 DP PHY has registers of QSERDES COM v2 and QSERDES TXRX v3.
Thus it may cause confusion that qmp_v2_xxx table and functions access
QSERDES TXRX v3 registers.

Rename QCS615 DP PHY variables and functions to be prefixed by qcs615
instead of qmp_v2.  This better aligns with how the driver names USB3 PHY
variables for QCM2290 etc.

Subject: [PATCH 0694/5214] dt-bindings: phy: qcom-edp: Add reference clock for
 sa8775p eDP PHY

The initial sa8775p eDP PHY binding contribution missed adding support for
voting on the eDP reference clock. This went unnoticed because the UFS PHY
driver happened to enable the same clock.

After commit 77d2fa54a945 ("scsi: ufs: qcom : Refactor phy_power_on/off
calls"), the eDP reference clock is no longer kept enabled, which results
in the following PHY power-on failure:

phy phy-aec2a00.phy.10: phy poweron failed --> -110

To fix this, explicit voting for the eDP reference clock is required.
This patch adds the eDP reference clock for sa8775p eDP PHY and updates
the corresponding example node.

Subject: [PATCH 0695/5214] phy: qcom: m31-eusb2: Make USB repeater optional

A repeater is not required for the PHY to function. On systems with
multiple PHY instances connected to a multi-port controller, some PHYs
may be unconnected. All PHYs must still probe successfully even without
attached repeaters, otherwise the controller probe fails.

So make it optional.

Subject: [PATCH 0696/5214] phy: lynx-28g: use timeouts when waiting for lane
 halt and reset

There are various circumstances in which a lane halt, or a lane reset,
will fail to complete. If this happens, it will hang the kernel, which
only implements a busy loop with no timeout.

The circumstances in which this will happen are all bugs in nature:
- if we try to power off a powered off lane
- if we try to power off a lane that uses a PLL locked onto the wrong
  refclk frequency (wrong RCW, but SoC boots anyway)

Actually, unbounded loops in the kernel are a bad practice, so let's use
read_poll_timeout() with a custom function that reads both LNaTRSTCTL
(lane transmit control register) and LNaRRSTCTL (lane receive control
register) and returns true when the request is done in both directions.

The HLT_REQ bit has to clear, whereas the RST_DONE bit has to get set.

Any time such an error happens, it is catastrophic and there is no point
in trying to propagate it to our callers:
- if lynx_28g_set_mode() -> lynx_28g_power_on() times out, we have
  already reconfigured the lane, but returning an error would tell the
  caller that we didn't
- if lynx_28g_power_off() times out, again not much for the consumer to
  do to help get out of this situation - the phy_power_off() call is
  probably made from a context that the consumer can't cancel, or it is
  making it to return to a known state from a previous failure.

So just print an error if timeouts happen and let the driver control
flow continue. The entire point is just to not let the kernel freeze.

Subject: [PATCH 0697/5214] phy: lynx-28g: truly power the lanes up or down

The current procedure for power_off() and power_on() is the same as the
one used for major lane reconfiguration, aka halting. But this is
incorrect.

One would expect that a powered off lane causes the CDR (clock and data
recovery) loop of the link partner to lose lock onto its RX stream
(which suggests there are no longer any bit transitions => the channel
is inactive). However, it can be observed that this does not take place
(the CDR lock is still there), which means that a halted lane is not
powered off.

Implement the procedure mentioned in the block guide for powering down
a lane, and then back on. This means:

- lynx_28g_power_off() currently emits a HLT_REQ and waits for it to
  clear. Rename it to lynx_28g_lane_halt() and keep using it for
  lynx_28g_set_mode().
- lynx_28g_power_on() currently emits a RST_REQ and waits for it to
  clear. This is the reset procedure - rename it to
  lynx_28g_lane_reset(), and keep using it for lynx_28g_set_mode().

The "real" lynx_28g_power_off() should emit a STP_REQ and wait for it to
clear. And the "real" lynx_28g_power_on() should clear the DIS bit and
then perform a lane reset. Hook these methods to the phy_ops ::
power_off() and power_on() instead.

As opposed to lynx_28g_power_off() which is also directly hooked to the
PHY API, lynx_28g_lane_halt() isn't; just to lynx_28g_set_mode(), and
the call is being made in a state where we haven't yet made any change
to the lane. So it does make some limited amount of sense to code this
up such that if it fails, we make an attempt to reset the lane anyway
and let the consumer know that phy_set_mode_ext() failed.

Sort the field definitions in LNaTRSTCTL and LNaRRSTCTL in descending
order, and add new definitions for STP_REQ and DIS, previously unused.

Subject: [PATCH 0698/5214] phy: lynx-28g: implement phy_exit() operation

On Layerscape, some Lynx SerDes consumers go through the PHY framework
(we call these 'managed' for the sake of this discussion; they are some
Ethernet lanes), and some consumers don't go through the PHY framework
(we call these 'unmanaged'; they are some unconverted Ethernet lanes,
plus all SATA and PCIe controllers).

A lane is initially unmanaged, and becomes managed when phy_init() is
called on it. Similarly, it becomes unmanaged again when phy_exit() is
called.

Managed lanes are supposed to have power management through
phy_power_on() and phy_power_off().

The lynx-28g SerDes driver, when it probes, probes on all lanes, but
needs to be careful to keep the unmanaged lanes powered on, because
those might be in use by consumers unaware that they need to call
phy_init() and phy_power_on(). This also applies after phy_exit() is
called - no guarantee is made about how the port may be used
afterwards - may be DPDK, may be something else which is unaware of
the PHY framework.

Given this state table:

 State  | Consumer calls phy_exit()? | Provider implements phy_exit()?
 -------+----------------------------+--------------------------------
 (a)    | no                         | no
 (b)    | no                         | yes
 (c)    | yes                        | no
 (d)    | yes                        | yes

we are currently in state (a). This has the problem that when the
consumer fails to probe with -EPROBE_DEFER or is otherwise unbound,
the phy->init_count remains elevated and the lane never returns to the
unmanaged state (temporarily or not) as it should. Furthermore, the
second and subsequent phy_init() consumer calls are never passed on to
the provider driver.

We solve the above problem by implementing phy_exit() in the consumer,
and that moves us to state (c). But this creates the problem that a
balanced set of phy_init() and phy_exit() calls from the consumer will
effectively result in multiple lynx_28g_init() calls as seen by the
SerDes and nothing else - as the optional phy_ops :: exit() is not
implemented. But that actually doesn't work - the 28G Lynx SerDes can't
power down a lane which is already powered down; that call sequence
would time out and fail.

So actually we want to be in state (d), where both the provider and the
consumer implement phy_exit(). But we can only do that safely through
intermediary state (b), where the provider implements it first. This
effectively behaves just like (a), except it offers a safe migration
path for the consumer to call phy_exit() as mandated by the Generic PHY
API.

Extra development notes: ignoring the lynx_28g_power_on() error in
lynx_28g_exit() is a deliberate decision. The consumer can't deal with a
teardown path that is not error-free. Ignoring the error is not silent:
lynx_28g_power_on() -> lynx_28g_lane_reset() will print on failure.

Subject: [PATCH 0703/5214] phy: freescale: imx8qm-hsio: provide regmap names

This driver uses multiple regmaps, which will causes name conflicts
in debugfs like:
  debugfs: '5f1a0000.phy' already exists in 'regmap'
Fix this by using a dedicated regmap config for each resource, each
having a dedicated regmap name.

Subject: [PATCH 0705/5214] KVM: x86/mmu: separate more EPT/non-EPT
 permission_fault()

Move more of EPT handling entirely in the existing "if (!ept)"
conditional.  Use a new "rf" variable instead of uf for read permissions
for clarity.

Merge smepf and ff into a single variable because EPT's "SMEP" (actually
MBEC) is defined differently and does not need smepf.

Subject: [PATCH 0706/5214] KVM: x86/mmu: introduce ACC_READ_MASK

Read permissions so far were only needed for EPT, which does not need
ACC_USER_MASK.  Therefore, for EPT page tables ACC_USER_MASK was repurposed
as a read permission bit.

In order to implement nested MBEC, EPT will genuinely have four kinds of
accesses, and there will be no room for such hacks; bite the bullet at
last, enlarging ACC_ALL to four bits and permissions[] to 2^4 bits (u16).

The new code does not enforce that the XWR bits on non-execonly processors
have their R bit set, even when running nested: none of the shadow_*_mask
values have bit 0 set, and make_spte() genuinely relies on ACC_READ_MASK
being requested!  This works because, if execonly is not supported by the
processor, shadow EPT will generate an EPT misconfig vmexit if the XWR
bits represent a non-readable page, and therefore the pte_access argument
to make_spte() will also always have ACC_READ_MASK set.

Subject: [PATCH 0707/5214] KVM: x86/mmu: pass PFERR_GUEST_PAGE/FINAL_MASK to
 kvm_translate_gpa

The XS/XU bit for EPT are only applied to final accesses, and use the
U bit from the page walk itself.  While strictly speaking not necessary
(any value of PFERR_USER_MASK would be the same for page table accesses,
because they're reads and writes only), it is clearer and less hackish
to only apply MBEC to PFERR_GUEST_FINAL_MASK.  Allow kvm-intel.ko to
distinguish the two cases.

The XS/XU bit for EPT are only applied to final accesses, and use the

Subject: [PATCH 0709/5214] KVM: x86: make translate_nested_gpa vendor-specific

EPT and NPT have different rules for passing PFERR_USER_MASK to the
nested page table walk.  In particular, for final addresses EPT
uses the U bit of the guest (nGVA->nGPA) walk.

While at it, remove PFERR_USER_MASK from the VMX version of the
function, since it is actually ignored by the tables that
update_permission_bitmask() generates for EPT.

Subject: [PATCH 0710/5214] KVM: x86/mmu: split XS/XU bits for EPT

When EPT is in use, replace ACC_USER_MASK with ACC_USER_EXEC_MASK,
so that supervisor and user-mode execution can be controlled
independently (ACC_USER_MASK would not allow a setting similar to
XU=0 XS=1 W=1 R=1).

Replace shadow_x_mask with shadow_xs_mask/shadow_xu_mask, to allow setting
XS and XU bits separately in EPT entries.

In fact, ACC_USER_EXEC_MASK is already set through ACC_ALL in the
kvm_mmu_page roles and propagates to the XU bit of sPTEs even if
MBEC is not (yet) enabled in the execution controls.  This is fine,
because the XU bit is ignored by the processor, and even once KVM
supports MBEC this mode will remain for processors that lack the
feature.

Subject: [PATCH 0711/5214] KVM: x86/mmu: move cr4_smep to base role

Guest page tables can be reused independent of the value of CR4.SMEP
(at least if WP=1).  However, this is not true of EPT MBEC pages,
because presence of EPT entries is signaled by bits 0-2 when MBEC
is off, and bits 0-2 + bit 10 when MBEC is on.

In preparation for enabling MBEC, move cr4_smep to the base role.
This makes the smep_andnot_wp bit redundant, so remove it.

Subject: [PATCH 0712/5214] KVM: VMX: enable use of MBEC

If available, set SECONDARY_EXEC_MODE_BASED_EPT_EXEC in the secondary
execution controls.

The changes are limited because the MMU is designed to create the same
sPTEs independent of the MBEC setting.  On hosts lacking support for
MBEC, and in nested guests which cannot enable it as of this commit,
the XU bit is ignored by the processor.

Note that, as of this patch, MBEC is not available to L1 hypervisors
for their guests.

Subject: [PATCH 0714/5214] KVM: nVMX: pass PFERR_USER_MASK to MMU on EPT
 violations

For EPT, PFERR_USER_MASK refers not to the CPL of the guest,
but to the AND of the U bits encountered while walking guest
page tables; this is consistent with how MBEC differentiates
between XS and XU.  This is available through the
"advanced vmexit information for EPT violations" feature.

Subject: [PATCH 0715/5214] KVM: x86/mmu: add support for MBEC to EPT page
 table walks

Extend the page walker to support moving bit 10 of the PTEs
into ACC_USER_EXEC_MASK and bit 6 of the exit qualification of
EPT violation VM exits.

Note that while mmu_has_mbec()/cr4_smep affect the interpretation of
ACC_USER_EXEC_MASK and add bit 10 as a "present bit" in guest EPT page
table entries, they do not affect how KVM operates on SPTEs.  That's
because the MMU uses explicit ACC_USER_EXEC_MASK/shadow_xu_mask even for
the non-nested EPT; the only difference is that ACC_USER_EXEC_MASK and
ACC_EXEC_MASK will always be set in tandem outside the nested scenario.

Subject: [PATCH 0716/5214] KVM: nVMX: advertise MBEC to nested guests

Advertise SECONDARY_EXEC_MODE_BASED_EPT_EXEC (MBEC) to userspace, which
allows userspace to expose and advertise the feature to the guest.

When MBEC is enabled by the guest, it is passed to the MMU via cr4_smep,
and to the processor by the merging of vmcs12->secondary_vm_exec_control
into the VMCS02's secondary VM execution controls.

Subject: [PATCH 0717/5214] KVM: nVMX: allow MBEC with EVMCS

Extend EVMCS1_SUPPORTED_2NDEXEC to allow MBEC and EVMCS to coexist.
Presenting both EVMCS and MBEC simultaneously causes KVM to filter out
MBEC and not present it as a supported control to the guest, preventing
performance gains from MBEC when Windows HVCI is enabled.

The guest may choose not to use MBEC (e.g., if the admin does not enable
Windows HVCI / Memory Integrity), but if they use traditional nested
virt (Hyper-V, WSL2, etc.), having EVMCS exposed is important for
improving nested guest performance. IOW allowing MBEC and EVMCS to
coexist provides maximum optionality to Windows users without
overcomplicating VM administration.

Subject: [PATCH 0718/5214] KVM: x86/mmu: propagate access mask from root pages
 down

Until now, all SPTEs have had all kinds of access allowed; however,
for GMET to be enabled all the pages have to have ACC_USER_MASK
disabled.  By marking them as supervisor pages, the processor
allows execution from either user or supervisor mode (unlike
for normal paging, NPT ignores the U bit for reads and writes).
That will mean that the root page's role has ACC_USER_MASK
cleared and that has to be propagated down through the kvm_mmu_page
tree.

Do that, and pass the required access to the
kvm_mmu_spte_requested tracepoint since it's not ACC_ALL
anymore.

Subject: [PATCH 0719/5214] KVM: x86/mmu: introduce cpu_role bit for
 availability of PFEC.I/D

While GMET looks a lot like SMEP, it has several annoying differences.
The main one is that the availability of the I/D bit in the page fault
error code still depends on the host CR4.SMEP and EFER.NXE bits.  If the
base.cr4_smep bit of the cpu_role is (ab)used to enable GMET, there needs
to be another place where the host CR4.SMEP is read from; just merge it
with EFER.NXE into a new cpu_role bit that tells paging_tmpl.h whether
to set the I/D bit at all.

Subject: [PATCH 0720/5214] KVM: SVM: add GMET bit definitions

GMET (Guest Mode Execute Trap) is an AMD virtualization feature,
essentially the nested paging version of SMEP.  Hyper-V uses it;
add it in preparation for making it available to hypervisors
running under KVM.

Subject: [PATCH 0721/5214] KVM: x86/mmu: hard code more bits in
 kvm_init_shadow_npt_mmu

The host CR0 does not really reflect onto the NPT format because
hCR0.PG=1 must be set and hCR0.WP is ignored.  Carve that in stone
by removing the cr0 argument from kvm_init_shadow_npt_mmu.

Pass in WP=1 as well; it does not matter for GMET disabled because
PFERR_USER_MASK is always set, but a cleared W bit in the nested page
tables cannot be overridden in supervisor mode when GMET is enabled,
either.  In fact, since CR0.WP=0 is the weird "extra accesses allowed"
mode, it is acutally easier think about it being always set.

Likewise, clear X86_CR4_SMAP to avoid that KVM erroneously faults on
supervisor accesses to an U=1 page.

Subject: [PATCH 0722/5214] KVM: x86/mmu: add support for GMET to NPT page
 table walks

GMET allows page table entries to be created with U=0 in NPT.
However, when GMET=1 U=0 only affects execution, not reads or
writes.  Ignore user faults on non-fetch accesses for NPT GMET.

Subject: [PATCH 0724/5214] KVM: SVM: work around errata 1218

According to AMD, the hypervisor may not be able to determine whether a
fault was a GMET fault or an NX fault based on EXITINFO1, and software
"must read the relevant VMCB to determine whether a fault was a GMET
fault or an NX fault".  The APM further details that they meant the
CPL field.

KVM uses the page fault error code to distinguish the causes of a
nested page fault, so recalculate the PFERR_USER_MASK bit of the
vmexit information.  Only do it for fetches and only if GMET is in
use, because KVM does not differentiate based on PFERR_USER_MASK
for other nested NPT page faults.

Subject: [PATCH 0725/5214] KVM: nSVM: enable GMET for guests

All that needs to be done is moving the GMET bit from vmcb12 to vmcb02.
The only new thing is that __nested_copy_vmcb_control_to_cache now
ensures that ignored-if-unavailable bits are zero in svm->nested.ctl.

Subject: [PATCH 0726/5214] USB: serial: mxuport: update number-of-ports
 encoding

In preparation for adding support for 3, 5, 6 and 7 port devices, replace
the current one-bit-per-type encoding of the number of ports with a more
compact four bit encoding (2..16 ports or undefined).

Subject: [PATCH 0729/5214] USB: serial: xr: add missing uaccess include

Add the missing uaccess.h include, which is needed since TIOCSRS485
support was added, instead of relying on the header being included
indirectly.

Subject: [PATCH 0735/5214] staging: vme_user: remove unnecessary NULL
 initialization before list iteration

Remove redundant NULL initialization for list iterator because
variables used as iterators in list_for_each_entry() do not require
initialization, as the macro assigns them before first use.

No functional change.

Replace remaining pr_err() calls with netdev_err() where a net device
is available to provide better context in error messages.

Lines in skb_to_mep() are left as pr_err() since no net device
context is available there.

to check there are no other occurrences.

Subject: [PATCH 0748/5214] staging: rtl8723bs: Replace uint with unsigned int
 in core

Replace the uint type with unsigned int in the rtl8723bs core code.

This removes unnecessary typedef use and moves the driver closer to
standards.

No functional changes intended.

Subject: [PATCH 0767/5214] staging: rtl8723bs: replace non-standard BITn
 macros with BIT(n)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the local BIT0-BIT31 macro definitions from osdep_service.h
and replace all usages with the kernel's BIT(n) macro from <linux/bitops.h>.

NOTE: DYNAMIC_BB_DYNAMIC_TXPWR is defined as BIT2 and used
in a bitwise NOT expression. Migrating to BIT(2) causes an
-Werror=overflow warning due to the unsigned long result not
fitting in u32. This instance has been left unconverted.

Compile-tested only.

Subject: [PATCH 0769/5214] pinctrl: renesas: rzg2l: Make QSPI register
 handling conditional

The QSPI register at offset 0x3008 is not present on all SoCs supported by
the RZ/G2L pinctrl driver. Unconditionally reading and writing this
register during suspend/resume on hardware that lacks it can cause
undefined behaviour.

Add a qspi field to rzg2l_register_offsets to allow per-SoC declaration of
the QSPI register offset, and guard the suspend/resume accesses with a
check on that field. Populate the offset only for the RZ/{G2L,G2LC,G2UL,
Five} hardware configuration, which is where the register is known to
exist.

Subject: [PATCH 0770/5214] pinctrl: renesas: rzg2l: Add support for selecting
 power source for {WDT,AWO,ISO}

The RZ/G3L SoC has support for setting power source that are not
controlled by the following voltage control registers:
  - SD_CH{0,1,2}_POC, XSPI_POC, ETH{0,1}_POC, I3C_SET.POC

Add support for selecting voltages using OTHER_POC register for
setting I/O domain voltage for WDT, ISO and AWO by extending
rzg2l_caps_to_pwr_reg() with a mask output parameter so that callers
callers can identify which bit(s) within OTHER_POC correspond to the
requested domain. Update rzg2l_get_power_source() to extract the
relevant bit field via field_get() when reading OTHER_POC, and update
rzg2l_set_power_source() to perform a read-modify-write under the
spinlock when writing to OTHER_POC, since multiple domains share the
same register.

Subject: [PATCH 0771/5214] pinctrl: renesas: rzg2l: Update OEN pin validation
 to use exact match

The RZ/G2L SoC uses pin 0 from a port for OEN while RZ/G3L uses pin 1. The
existing greater-than comparison against oen_max_pin in
rzg2l_pin_to_oen_bit() would incorrectly accept any pin below that value
rather than enforcing the single valid OEN pin for each SoC. Replace the
range check with an exact equality test so that only the designated OEN
pin is accepted.

Subject: [PATCH 0773/5214] pinctrl: renesas: rzg2l: Simplify
 rzg2l_pinctrl_set_mux()

The port and function selectors are evaluated multiple times
in rzg2l_pinctrl_set_mux(). Simplify the function by dropping
dupicate evaluation storing them in local variables.

Subject: [PATCH 0774/5214] pinctrl: renesas: rzg2l: Add support for clone
 channel control

The RZ/G3L SoC has some IP such as I2C ch{2,3},SCIF ch{3,4,5},
RSPI ch{1,2} and RSCI ch{1,2,3} need to control the clone channel for
proper operation. As per the RZ/G3L hardware manual, the clone channel
setting is to be done before the mux setting.

On 64-bit platforms, "unsigned long" is 64-bit.  Hence checking if all
"unsigned long" configuration values are equal should be done using an
"unsigned long" temporary.

Subject: [PATCH 0777/5214] thunderbolt: test: add KUnit regression tests for
 XDomain property parser

Add three KUnit cases that exercise the defects fixed by the sibling
commits in this series by feeding crafted XDomain property blocks to
tb_property_parse_dir():

  tb_test_property_parse_u32_wrap - entry->value = 0xffffff00 and
    entry->length = 0x100 so their u32 sum 0x100000000 wraps to 0
    under the block_len guard; without the fix the subsequent
    parse_dwdata() reads attacker-directed OOB memory.

  tb_test_property_parse_recursion - two DIRECTORY entries pointing
    at each other, driving __tb_property_parse_dir() recursion;
    without the fix the kernel stack is exhausted.

  tb_test_property_parse_dir_len_underflow - a DIRECTORY entry with
    length < 4 placed near the end of the block so the non-root UUID
    kmemdup of 4 dwords from dir_offset reads OOB before the later
    content_len = dir_len - 4 underflow path is reached.

Each test asserts tb_property_parse_dir() returns NULL on the
crafted input.  With CONFIG_KASAN=y, running these on the pre-fix
kernel produces an oops inside __tb_property_parse_dir or its
callees: u32_wrap takes a page fault on the KASAN shadow lookup for
the wild ~16 GiB OOB offset; recursion trips a KASAN out-of-bounds
report in __unwind_start as the per-task kernel stack is consumed;
dir_len_underflow trips a KASAN slab-out-of-bounds report in
kmemdup_noprof reading 16 bytes past the 28-byte block.  Post-fix
they pass cleanly.

The crafted blocks are populated by writing u32 dwords directly,
matching the existing root_directory[] style used elsewhere in
this file rather than imposing a private struct overlay.

Run with:
  ./tools/testing/kunit/kunit.py run --arch=x86_64 \
    --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_NVMEM=y \
    --kconfig_add CONFIG_USB4=y --kconfig_add CONFIG_USB4_KUNIT_TEST=y \
    --kconfig_add CONFIG_KASAN=y 'thunderbolt.tb_test_property_parse_*'

Subject: [PATCH 0778/5214] dt-bindings: power: Add power-domains-child-ids
 property

Add binding documentation for the new power-domains-child-ids property,
which works in conjunction with the existing power-domains property to
establish parent-child relationships between a multi-domain power domain
provider and external parent domains.

Each element in the uint32 array identifies the child domain
ID (index) within the provider that should be made a child domain of
the corresponding phandle entry in power-domains. The two arrays must
have the same number of elements.

Subject: [PATCH 0779/5214] firewire: Simplify storing pointers in device id
 struct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Technically it is fine (on all current Linux architectures) to store a
pointer in an unsigned long variable. However this needs explicit
casting which is an easy source for type mismatches.

By replacing the plain unsigned long .driver_data in struct
ieee1394_device_id by an anonymous union, most of the casting can be
dropped. There is still some implicit casting involved (between a void *
and a driver specific pointer type), but that's better than the approach
to store a pointer in an unsigned long variable as this doesn't lose the
information that the data being pointed to is const.

All users of struct ieee1394_device_id are initialized in a way that is
compatible with the new definition, so no adaptions are needed there.

(The comments addressing to CHERI extension are dropped by the
maintainer.)

Subject: [PATCH 0781/5214] pmdomain: core: add support for
 power-domains-child-ids

Currently, PM domains can only support hierarchy for simple
providers (e.g. ones with #power-domain-cells = 0).

Add support for oncell providers as well by adding a new property
`power-domains-child-ids` to describe the parent/child relationship.

For example, an SCMI PM domain provider has multiple domains, each of
which might be a child of diffeent parent domains. In this example,
the parent domains are MAIN_PD and WKUP_PD:

    scmi_pds: protocol@11 {
        reg = <0x11>;
        #power-domain-cells = <1>;
        power-domains = <&MAIN_PD>, <&WKUP_PD>;
        power-domains-child-ids = <15>, <19>;
    };

With this example using the new property, SCMI PM domain 15 becomes a
child domain of MAIN_PD, and SCMI domain 19 becomes a child domain of
WKUP_PD.

To support this feature, add two new core functions

- of_genpd_add_child_ids()
- of_genpd_remove_child_ids()

which can be called by pmdomain providers to add/remove child domains
if they support the new property power-domains-child-ids.

The add function is "all or nothing".  If it cannot add all of the
child domains in the list, it will unwind any additions already made
and report a failure.

Subject: [PATCH 0782/5214] pmdomain: arm_scmi: add support for domain
 hierarchies

After primary SCMI pmdomain is created, use new of_genpd helper which
checks for child domain mappings defined in power-domains-child-ids.

Also remove any child domain mappings when SCMI domain is removed.

Subject: [PATCH 0784/5214] x86/platform/olpc: xo15: Convert ACPI driver to a
 platform one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware.  Accordingly, a struct platform_driver should be
used by driver code to bind to that device.  There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].

Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert the olpc-xo15-sci ACPI driver to a platform
one.

After this change, the wakeup source added by the driver will appear
under the platform device used for driver binding, but the sysfs
attribute added by the driver under the ACPI companion of that device
will stay there in case there are utilities in user space expecting it
to be there.

While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.

Subject: [PATCH 0786/5214] platform/x86: pmc_atom: Use named initializer for
 pci_device_id array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being more verbose using a named initializer yields easier to
understand code and doesn't rely on the two hidden zeros in the
PCI_VDEVICE macro.

This doesn't introduce any changes to the compiled result of the array,
which was confirmed with an ARCH=x86 build.

Subject: [PATCH 0787/5214] ecryptfs: remove redundant variable found_auth_tok

The found_auth_tok variable is no longer needed, as the fact of finding
a token is determined directly by jumping to the found_matching_auth_tok
label inside the loop.

Remove found_auth_tok, simplifying the function logic.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Subject: [PATCH 0791/5214] serial: 8250_port: recognize UPIO_AU

My MIPS Alchemy systems generate the following warning during
probe of the 8250 driver:

WARNING: drivers/tty/serial/8250/8250_port.c:462 at set_io_from_upio+0xfc/0x124, CPU#0: swapper/0/1
Unsupported UART type 4
[...]

[<805214ec>] serial8250_probe+0x160/0x1e8
[<8053b5f0>] platform_probe+0x64/0x90

The least invasive fix is to recognize UPIO_AU (type 4) in set_io_from_upio()
and do nothing, since all parameters have already been set up in
8250_rt288x.c::au_platform_setup().

Run-tested on Alchemy Au1300 platform.

Subject: [PATCH 0792/5214] tty: synclink_gt: remove broken driver

The synclink_gt driver was marked as broken in commit 426263d5fb40
("tty: synclink_gt: mark as BROKEN") in July 2023 because it had severe
structural problems and there had been no evidence of users since 2016.
Since then, no meaningful improvements have been made to the driver,
and it is unlikely that will ever happen due to the lack of interest.
Drop the driver and references to it in comments and documentation.
include/uapi/linux/synclink.h is also removed. The only use of this
header I have found is the linux-raw-sys Rust crate. It generates
bindings for all UAPI headers, but has a hardcoded list of headers and
ioctls, including this one, so that does not indicate that anyone is
using it. I have sent a pull request to remove the include and ioctl
definitions for this header (see the link below).

Subject: [PATCH 0793/5214] serial: 8250_pci: Consistently define
 pci_device_ids using named initializers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

... and PCI device helpers.

The various struct pci_device_id were defined using a mixture of
initialization by position and by name. Some use the PCI device helpers
(like PCI_DEVICE and PCI_DEVICE_SUB) and others don't.

Consistently use named initializers, drop assignments of 0 by position
for .class and .class_mask and use the PCI device helpers. Also use
consistent line-breaks and positioning for opening and closing curly
braces.

The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.

This patch doesn't change the compiled result; this was verified using
an allmodconfig with several things disabled that make reproducible
builds harder on x86 and arm64.

Subject: [PATCH 0794/5214] serial: jsm: Drop unused driver_data assigment and
 redundant zeros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver doesn't use the driver_data field, so drop the assigment
together with the then redundant zero assigment for .class and
.class_mask. Also drop the zero in the list terminator.

While at it also use PCI_VDEVICE() to allow dropping "PCI_VENDOR_ID_".

Subject: [PATCH 0796/5214] serial: core: Add dedicated uart_port field for
 console flow

Currently the UPF_CONS_FLOW bit in the uart_port.flags field is used
by serial console drivers to identify if a user has configured flow
control on the console. Usually this policy is setup during early
boot, but can be changed at runtime.

The bits in uart_port.flags are either hardware and driver
properties that are initialized before usage or are properties that
can be changed via the tty layer.

The UPF_CONS_FLOW bit is an exception because it is a console-only
policy that can change at runtime and its setting and usage have
nothing to do with the tty layer. This actually causes a problem
for its usage because uart_port.flags is synchronized by a related
tty_port.mutex, but a console has no relation to a tty (other than
sharing the port).

This is probably why console flow control is not properly available
for most serial drivers. And it is hindering being able to provide a
proper implementation. Commit d01f4d181c92 ("serial: core: Privatize
tty->hw_stopped") addressed a similar issue to deal with software
assisted CTS flow state tracking.

Add a new uart_port boolean field "cons_flow" to store the user
configuration for console flow control. Add getter/setter wrappers
to allow for adding more policies later and/or locking constraint
validation.

Mark UPF_CONS_FLOW as deprecated.

Subject: [PATCH 0797/5214] serial: Replace driver usage of UPF_CONS_FLOW

Rather than using the UPF_CONS_FLOW bit of uart_port.flags to track
the user configuration of console flow control, use the newly added
uart_port.cons_flow (via its getter/setter functions).

A coccinelle script was used to perform the search/replace.

Note1: The sh-sci driver is blindly copying platform data configuration
       flags to uart_port.flags. Thus UPF_CONS_FLOW could get set for
       uart_port.flags. A follow-up commit will address this.

Note2: The samsung_tty driver is using UPF_CONS_FLOW as a platform data
       configuration flag. However, the driver explicitly checks for
       this configuration flag and thus setting UPF_CONS_FLOW in
       uart_port.flags is avoided.

 DW_UART_CPR_* definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the magic CPR value for Renesas RZ/N1 with a composition using
DW_UART_CPR_* bit/field definitions and FIELD_PREP_CONST().

Introduce a helper macro to convert a FIFO size (bytes) into the CPR
FIFO_MODE field value, with BUILD_BUG_ON_ZERO() checks for alignment and
bounds. Use it to replace the literal FIFO_MODE values in the RZN1.

Provide a fixed CPR value for the DP1000-specific compatible so the

Subject: [PATCH 0806/5214] serial: core: prevent division by zero by always
 returning non-zero baud rate

If a device has a minimum baud rate > 9600 bauds, and a new termios baud
rate of 0 (hang up) is requested, uart_get_baud_rate() will return 0.
Most drivers do not check this return value and call uart_update_timeout()
with this zero baud rate, which will trigger a "Division by zero in kernel"
fault:

  stty -F /dev/ttySC0 0

  Division by zero in kernel.
  ...

Fix by returning the larger of 9600 or min for the B0 case. This now
ensures that a non-zero baud rate is returned, and greatly simplifies the
code.

Subject: [PATCH 0808/5214] serial: max310x: simplify max310x_update_best_err()

besterr was defined as a signed type was to make sure that the first call
to max310x_update_best_err() would always set besterr. Also there is no
need for it to be a long. By changing its type to unsigned int and initial
value to UINT_MAX, max310x_update_best_err() can be simplified and be more
efficient while achieving the same initial result.

 max310x_set_ref_clk()

Having max310x_set_ref_clk() return an s32 as both an error code
and a frequency value is ambiguous. Fix by passing a pointer to the
frequency value that will then be updated, and simply return a status.

Subject: [PATCH 0811/5214] serial: max310x: improve max310x_set_ref_clk()
 efficiency

The same basic code is duplicated for each of the four PLL multiplier
values, so simplify and streamline it. Doing so allows us to avoid
some unnecessary (fdiv * factor) multiplications for some fdiv values and
replace the second "if" statement with an "else if" and avoid a useless
comparison.

Subject: [PATCH 0817/5214] serial: qcom-geni: Avoid probing debug console UART
 without console support

When CONFIG_SERIAL_QCOM_GENI_CONSOLE is disabled, the driver still
advertises the debug UART compatible strings ("qcom,geni-debug-uart"
and "qcom,sa8255p-geni-debug-uart") in its of_match table. This lets the
driver match and probe console UART DT nodes even though console
support is not built. As a result, the console port is never registered
with the UART core and uart_add_one_port() fails with -EINVAL.

Fix this by only including the debug UART compatible entries in the
match table when CONFIG_SERIAL_QCOM_GENI_CONSOLE is enabled, preventing
the driver from probing console UART nodes when console support is
absent.

Content-Transfer-Encoding: 8bit

The device_set_wakeup_enable() call in ebook_switch_add() doesn't
actually do anything because power.can_wakeup is not set for ACPI
device objects.  Moreover, had it done anything, it would have
registered a wakeup source object that wouldn't have been used
going forward and that wakeup source would have been leaked after
driver removal because ebook_switch_remove() doesn't clean it up.
Accordingly, remove that call from ebook_switch_add().

Also prevent leaking an enabled ACPI GPE after removing the driver by
adding appropriate cleanup code to ebook_switch_remove().

Subject: [PATCH 0824/5214] platform/x86: xo15-ebook: Register ACPI notify
 handler directly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To facilitate subsequent conversion of the driver to a platform one,
make it install an ACPI notify handler directly instead of using
a .notify() callback in struct acpi_driver.

No intentional functional impact.

Subject: [PATCH 0825/5214] platform/x86: xo15-ebook: Convert ACPI driver to a
 platform one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware.  Accordingly, a struct platform_driver should be
used by driver code to bind to that device.  There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].

Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert the OLPC XO-1.5 ebook switch driver from an
ACPI driver to a platform one.

After this change, the input device registered by the driver will appear
under the platform device used for driver binding.

While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.

Subject: [PATCH 0826/5214] platform/x86: sel3350-platform: Retain LED state on
 load and unload
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the platform driver is loaded or unloaded, it overwrites the
existing LED states. This can cause a loss of early boot state when the
driver loads, and it can cause the ALARM contact to change state or
flicker.

Explicitly retain the existing LED state to prevent overwriting on
driver load and unload.

Change to a flexible array member to allocate once instead of twice.

Use __counted_by for extra runtime analysis. Move the counting
variable assignment to right after allocation as done by
kzalloc_flex for GCC 15 and above.

Remove + 1 to allocation. It's already done in the previous line.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use a flexible array member to combine allocations. Avoids having to
free separately.

Add __counted_by for extra runtime analysis.

Move counting variable assignment to after allocations as is already
done by kzalloc_flex for GCC 15 and above.

Subject: [PATCH 0830/5214] perf test: Fix nanosleep check in the ftrace test

The perf ftrace test case runs:

  perf ftrace profile --graph-opts depth=5 sleep 0.1

and checks that the output contains a *clock_nanosleep function with a
count of 1.

This fails on a risc-v system that uses musl as its C library. musl's
nanosleep syscall wrapper uses either the nanosleep or the
clock_nanosleep syscall.

Filter for sys_*nanosleep to allow both syscalls.

Subject: [PATCH 0831/5214] perf test: Fix sys_enter_openat event test for musl

The "syscalls:sys_enter_openat event fields" test calls

openat(AT_FDCWD, "/etc/passwd", O_RDONLY | O_DIRECTORY)

and verifies that the flags of the captured event are matching.
This fails for musl, where the openat syscall wrapper always adds
O_LARGEFILE.

Update the check to allow for additional flags, the access mode flags
must be unchanged.

Subject: [PATCH 0832/5214] perf test: Fix "trace summary" test for musl-based
 systems

The trace summary test calls /bin/true and filters for open, read and
close events. These events are coming from shared library loads.

On a musl system, the loader and libc may point to the same file. true
needs only libc, no further shared libraries are loaded at startup. The
test fails since no open, read and close events are captured.

Run "cat /dev/null" instead of "true". This creates the required events
regardless of the C library and it works for cat from busybox or from
coreutils.

Subject: [PATCH 0833/5214] perf sched stats: Fix segmentation faults, memory
 leaks, and stale pointers in diff mode

The patch addresses multiple segmentation fault vectors, out-of-bounds
reads, and memory leaks in perf sched stats by adding bounds checks,
NULL checks, proper error propagation, and robust memory cleanup.

1. In get_all_cpu_stats(), added assert(!list_empty(head)) to prevent
   unsafe list_first_entry() calls on empty lists, added a missing NULL
   check for summary_head->cpu_data allocation, and implemented a cleanup
   ladder using a temporary list to prevent memory leaks on error paths.

2. In free_schedstat(), fixed memory leaks by ensuring internal domain_data
   and cpu_data pointers are freed.

3. In show_schedstat_data(), fixed a stale pointer issue where ds2 retained
   its value from a previous iteration when dptr2 became NULL, and added
   proper propagation of errors from get_all_cpu_stats().

4. Propagated show_schedstat_data() errors up to perf_sched__schedstat_diff()
   and perf_sched__schedstat_live() to prevent output corruption on failure.

5. In show_schedstat_data(), added NULL checks for cd_map1 and cd_map2
   to gracefully handle invalid or empty data files.

6. Added parallel iteration termination checks using list_is_last() in
   show_schedstat_data() for both domain and CPU lists to safely terminate
   at the end of each list when files contain a different number of CPUs
   or domains.

7. Added CPU bounds checks (cs1->cpu >= nr1 and cs2->cpu >= nr2) in
   show_schedstat_data() to prevent out-of-bounds reads from cd_map1 and
   cd_map2 when comparing files from machines with different CPU counts.

8. Added NULL checks for cd_info1 and cd_info2 to prevent crashes when
   a CPU has data samples but no corresponding domain info in the header.

9. Added domain bounds checks (ds1->domain >= cd_info1->nr_domains and
   ds2->domain >= cd_info2->nr_domains) to prevent out-of-bounds array
   accesses in the domains array.

10. Added NULL checks for dinfo1 and dinfo2 in show_schedstat_data()
    to prevent crashes when a domain has no corresponding domain info.

11. Zero-initialized the perf_data array in perf_sched__schedstat_diff()
    to prevent stack garbage from causing perf_data_file__fd() to attempt
    to use a NULL fptr when use_stdio happened to be non-zero.

Subject: [PATCH 0834/5214] perf sched: Add missing mmap2 handler in timehist

perf_sched__timehist() registers event handlers for options using the
sched->tool struct. It registers handlers for MMAP, COMM, EXIT, FORK, etc.
but completely omits registering a handler for MMAP2 events.

Failing to register both MMAP and MMAP2 handlers causes modern systems
(which primarily output MMAP2 records) to silently drop VMA map mappings.
This results in uninitialized machine/thread mapping structures, making it
impossible to resolve shared library instruction pointers (IPs) to dynamic
symbols/DSOs during timehist callchain analysis.

Fix this by correctly registering perf_event__process_mmap2 in
sched->tool inside perf_sched__timehist().

Subject: [PATCH 0835/5214] perf tool: Fix missing schedstat delegates and
 dont_split_sample_group in delegate_tool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

delegate_tool was missing the delegate overrides for schedstat_cpu
and schedstat_domain. As a result, when allocated with zalloc, these
callbacks defaulted to NULL, causing a segmentation fault crash if
any schedstat events were delivered during event processing.
Fix this by adding delegate_schedstat_cpu and delegate_schedstat_domain
via the CREATE_DELEGATE_OP2 macro, and ensuring delegate_tool__init
correctly registers them.

Additionally, delegate_tool__init completely omitted copying the
dont_split_sample_group property from the delegate. This would cause
wrapper tools to default the flag to false, which corrupts piped event
processing (e.g., in perf inject) by triggering duplicate event
deliveries on split sample values in deliver_sample_group().

Similarly, perf_tool__init() omitted the initialization of this
boolean field. On stack-allocated tools that rely on this initializer
(like intel-tpebs or __cmd_evlist), this could result in uninitialized
stack garbage evaluating to true—silently dropping non-leader event
members in deliver_sample_group().

Fix both issues by properly copying the field in delegate_tool__init
and initializing it to false in perf_tool__init.

Fixes: 6331b266935916bf ("perf tool: Add a delegate_tool that just delegates actions to another tool")
Fixes: 79bcd34e0f3da39f ("perf inject: Fix leader sampling inserting additional samples")

Subject: [PATCH 0836/5214] pinctrl: mediatek: paris: bypass pinctrl GPIO layer
 in set GPIO direction

pinctrl_gpio_direction_input() / pinctrl_gpio_direction_output() take
the pinctrl mutex. This causes a gpiochip operations to need to sleep.
Worse yet, the .can_sleep field in the gpiochip is not set. This causes
the shared GPIO proxy to trip over, as it uses gpiod_cansleep() to check
whether it can use a spinlock or needs a mutex. In this case, it ends
up taking a spinlock, then calls pinctrl_gpio_direction_output(), which
takes a mutex. This causes a huge warning.

While this class of Mediatek hardware does not have separate clear/set
registers, the pinctrl context has a spinlock that is taken whenever
a register read-modify-write is done. Also, once the GPIO function is
selected / muxed in, further GPIO operations do not involve pinctrl
operations or state. The GPIO direction and level values do not require
toggling the pinmux or any other pin config options.

Switch to directly calling mtk_pinmux_gpio_set_direction() in the GPIO
set direction callbacks to avoid taking the pinctrl mutex. Drop the
.gpio_set_direction field in mtk_pmxops to signal we are no longer using
the pinctrl GPIO layer for setting the direction.

Subject: [PATCH 0837/5214] pinctrl: mediatek: common-v1: bypass pinctrl GPIO
 layer in set GPIO direction

pinctrl_gpio_direction_input() / pinctrl_gpio_direction_output() take
the pinctrl mutex. This causes a gpiochip operations to need to sleep.
Worse yet, the .can_sleep field in the gpiochip is not set. This causes
the shared GPIO proxy to trip over, as it uses gpiod_cansleep() to check
whether it can use a spinlock or needs a mutex. In this case, it ends
up taking a spinlock, then calls pinctrl_gpio_direction_output(), which
takes a mutex. This causes a huge warning.

Since the Mediatek hardware has separate clear/set registers, there is
no risk of clobbering other bits like with a read-modify-write pattern.
Also, once the GPIO function is selected / muxed in, further GPIO
operations do not involve pinctrl operations or state. The GPIO direction
and level values do not require toggling the pinmux or any other pin config
options.

Switch to directly calling mtk_pmx_gpio_set_direction() in the GPIO set
direction callbacks to avoid taking the pinctrl mutex. Drop the
.gpio_set_direction field in mtk_pmx_ops to signal we are no longer using
the pinctrl GPIO layer for setting the direction.

Subject: [PATCH 0839/5214] pinctrl: aspeed: Add AST2700 SoC0 support

Add pinctrl support for the SoC0 instance of the ASPEED AST2700.

AST2700 consists of two interconnected SoC instances, each with its own
pinctrl register block.

The SoC0 pinctrl hardware closely follows the design found in previous
ASPEED BMC generations, allowing the driver to build upon the common
ASPEED pinctrl infrastructure.

Subject: [PATCH 0847/5214] PCI: intel-gw: Move interrupt enable to own
 function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To improve the readability of the code, move the interrupt enable
instructions to a separate function. That is already done for the disable
interrupt instruction.

In addition, clear and disable all pending interrupts, as is done in
intel_pcie_core_irq_disable(). After that, enable all relevant interrupts
again. The 'PCIE_APP_IRNEN' definition contains all the relevant interrupts
that are of interest.

This change is also done in the MaxLinear SDK [1]. As I unfortunately don’t
have any documentation for this IP core, I suspect that the intention is to
set the IP core for interrupt handling to a specific state. Perhaps the
problem is that the IP core did not reinitialize the interrupt register
properly after a power cycle.

In my view, it can’t do any harm to switch the interrupt off and then on
again to set them to a specific state.

The reason why the MaxLinear SDK is used as a reference here is, that this
PCIe DWC IP is used in the URX851 and URX850 SoC. This SoC was originally
developed by Intel when they acquired Lantiq’s home networking division in
2015 [2]. In 2020 the home network division was sold to MaxLinear [3].
Since then, this SoC belongs to MaxLinear. They use their own SDK, which
runs on kernel version '5.15.x'.

MIME-Version: 1.0

To ensure that the boot sequence is correct, the DWC PCIe core clock must
be switched on before PHY init call [1]. This changes are based on patched
kernel sources of the MaxLinear SDK.

The reason why the MaxLinear SDK is used as a reference here is, that this

Subject: [PATCH 0850/5214] PCI: intel-gw: Fix ATU base address setup and add
 optional DT 'atu' region

The ATU base address was set in intel_pcie_host_setup(), which is called
via pp->ops->init(). However, dw_pcie_get_resources() runs before this
callback and sets a default atu_base of 0x300000, which then gets
overwritten by the driver's value of 0xC0000.

But this ordering is broken because atu_base must be set before
dw_pcie_get_resources() runs, not after. So move the atu_base assignment
from intel_pcie_host_setup() to intel_pcie_probe() to fix the
initialization order.

The call stack is:

  intel_pcie_probe
    dw_pcie_host_init
      dw_pcie_host_get_resources
        dw_pcie_get_resources       <- sets atu_base = 0x300000
      pp->ops->init
        intel_pcie_rc_init
          intel_pcie_host_setup     <- was overwriting atu_base here

Additionally, add support for parsing the ATU region from the device tree.
If an 'atu' region is present in DT, the DWC core parses it via
dw_pcie_get_resources() and the driver does not set atu_base explicitly.
If 'atu' is absent, the driver falls back to the hardcoded offset (0xC0000
from DBI base) for backwards compatibility, with a warning to the user.

Subject: [PATCH 0851/5214] dt-bindings: PCI: intel,lgm-pcie: Add 'atu'
 resource
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 'atu' information is already set in the dwc core, if it is specified in
the devicetree. The driver uses its own default, if not set in the
devicetree. This information is hardware-specific and should therefore be
maintained in the devicetree rather than in the source.

To be backward compatible, this field is not mandatory. If 'atu' resource
is not specified in the devicetree, the driver’s default value is used.

Subject: [PATCH 0852/5214] media: pci: add AVMatrix HWS capture driver

Add an in-tree AVMatrix HWS PCIe capture driver. The driver supports
up to four HDMI inputs and exposes the video capture path through
V4L2 with vb2-dma-contig streaming, DV timings, and per-input
controls. Audio support is intentionally omitted from this
submission.

This patch also adds the MAINTAINERS entry for the new driver.

This driver is derived from a GPL out-of-tree driver.

Changes since v6:
- v6 accidently contained legacy history, resubmitting with latest
- remove an unused mode-change label reported by W=1

Changes since v5:
- keep queue_setup() and alloc_sizeimage on the logical sizeimage value
- drop the dead queue_setup() fallback that rebuilt pix.sizeimage
  on the fly
- clarify that hws_calc_sizeimage() models the packed-YUYV-only path
- add Assisted-by attribution for Codex

Changes since v4:
- replace plain 64-bit elapsed-time divisions in debug logging with
  div_u64() so i386 module builds do not emit __udivdi3 references

Changes since v3:
- fold the MAINTAINERS update into this patch so per-patch CI sees the
  new file pattern
- wrap the validation text for checkpatch

Changes since v2:
- keep scratch DMA allocation on a single probe-owned path
- avoid double-freeing V4L2 control handlers on register unwind
- drop the extra per-node resolution sysfs ABI
- turn live geometry changes into explicit SOURCE_CHANGE renegotiation
- report live DV timings and reject attempts to retime a live source
- stop advertising RESOLUTION source changes for fps-only updates
- keep live fps state across harmless S_FMT restarts
- stop exposing an unvalidated DV RX power-present signal
- clean the imported sources for checkpatch and W=1 builds

Validation:
- build-tested with W=1 against a local kernel build tree
- compiled the driver with ARCH=i386 allmodconfig and verified the
  resulting hws_pci.o, hws_video.o, and hws.o do not reference
  __udivdi3
- v4l2-compliance 1.33.0-5459 from v4l-utils commit
  4a0d2c3b4f523406cb9a6f4c541ef14f72f19f3d on /dev/video2:
  48 tests succeeded, 0 failed, 1 warning

DV_RX_POWER_PRESENT is intentionally left unsupported in this revision
because current hardware evidence does not expose a validated
receiver-side power-detect signal distinct from active video presence.

Subject: [PATCH 0854/5214] media: tegra-video: vi: fix invalid u32 return
 value in format lookup

tegra_get_format_fourcc_by_idx() returns a u32 but uses -EINVAL to
signal an out-of-bounds index. This results in a large unsigned
value being returned, which may be interpreted as a valid fourcc.

Returning 0 is not a valid fourcc either. This condition should
never happen, so use WARN_ON_ONCE() to catch unexpected out-of-bounds
access and return a valid fallback format instead.

Subject: [PATCH 0861/5214] media: video-i2c: use vb2_video_unregister_device
 on driver removal

The driver uses vb2_fop_release() as its file release operation, so
vb2_video_unregister_device() should be used instead of
video_unregister_device() during driver removal.

This ensures that the vb2 queue is properly disconnected before the
video device is unregistered.

Subject: [PATCH 0862/5214] media: video-i2c: fix buffer queue ordering

Queued buffers are added to the tail of vid_cap_active in
buffer_queue(), but the capture kthread also retrieves buffers from
the tail of the list.

This makes the queue behave as LIFO instead of FIFO when multiple
buffers are queued.

Fix this by retrieving buffers from the head of the list.

Subject: [PATCH 0864/5214] media: airspy: Return queued buffers on
 start_streaming() failure

The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming().  If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.

airspy_start_streaming() returned -ENODEV early when the USB device had
been disconnected (s->udev == NULL) without returning any buffers that
buf_queue() had already accepted.  Take v4l2_lock first and jump to the
existing err_clear_bit label, which already drains s->queued_bufs via
vb2_buffer_done(..., VB2_BUF_STATE_QUEUED) before unlocking.

This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure").

Subject: [PATCH 0865/5214] media: msi2500: Return queued buffers on
 start_streaming() failure

The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming().  If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.

msi2500_start_streaming() had five error paths that all hit this trap
and were further tangled by ret-overwriting between calls:

  - -ENODEV when the USB device was already disconnected
  - -ERESTARTSYS when mutex_lock_interruptible() was interrupted
  - msi2500_set_usb_adc() failure: ret was silently overwritten by
    the next call (msi2500_isoc_init), so the error was lost entirely
  - msi2500_isoc_init() failure: cleanup_queued_bufs was called, but
    the function then fell through to msi2500_ctrl_msg() and again
    masked the original error by overwriting ret
  - msi2500_ctrl_msg(CMD_START_STREAMING) failure: no cleanup at all,
    leaving isoc URBs submitted with no way for the driver to consume
    them

Consolidate the error paths into a small goto chain.  Every failure
now stops the function, drains the queued-buffer list, and returns
the real error code.  The ctrl_msg failure path also rolls back the
preceding msi2500_isoc_init() via msi2500_isoc_cleanup() before
unlocking and draining.

The cleanup helper takes a vb2_buffer_state argument so that the
start_streaming error paths can pass VB2_BUF_STATE_QUEUED (as
expected by userspace on start_streaming failure) while stop_streaming
keeps its existing VB2_BUF_STATE_ERROR semantics.

This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure").

vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued

pwc's start_streaming() had two early returns that hit this trap:
-ENODEV when the USB device was already disconnected, and -ERESTARTSYS
when mutex_lock_interruptible() was interrupted by a signal.  Call the
existing pwc_cleanup_queued_bufs() helper with VB2_BUF_STATE_QUEUED

This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:

Subject: [PATCH 0867/5214] media: rtl2832_sdr: Return queued buffers on
 start_streaming() failure

The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming().  If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.

rtl2832_sdr_start_streaming() had multiple error paths that hit this
trap: two direct early returns (-ENODEV, -ERESTARTSYS), plus six
`goto err` paths covering subdev s_power, tuner setup, ADC setup,
stream-buffer allocation, urb allocation, and urb submission failures.
None of them returned the queued buffers.

The original function had no distinct success exit and fell straight
through into the err label, which previously only did mutex_unlock and
"return ret".  Adding queued-buffer cleanup at err must therefore be
paired with an explicit success return; otherwise every successful
start would also drain the buffer queue and kill streaming.  Add that
success return, then add rtl2832_sdr_cleanup_queued_bufs() at the err
label and before each early return.

The cleanup helper takes a vb2_buffer_state argument so that the
start_streaming error paths can pass VB2_BUF_STATE_QUEUED (as
expected by userspace on start_streaming failure) while stop_streaming
keeps its existing VB2_BUF_STATE_ERROR semantics.

This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure").

The err label still does not roll back power_ctrl(), frontend_ctrl(),
the POWER_ON flag, or stream/URB allocations that may have happened
before the failing step.  Those are pre-existing leaks of a different
class and are not addressed here.

Subject: [PATCH 0868/5214] media: stm32-dcmipp: Return queued buffers on
 start_streaming() failure

The vb2 framework hands buffers to the driver via buf_queue() before
calling start_streaming().  If start_streaming() returns an error
without first returning those buffers via vb2_buffer_done(),
vb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued
buffers leak.

dcmipp_bytecap_start_streaming() returned -EINVAL when the source
subdevice could not be resolved from the media graph, before
pm_runtime_resume_and_get() and media_pipeline_start() had been called.
The remaining error paths already converge on the err_buffer_done
label, which calls dcmipp_bytecap_all_buffers_done(...,
VB2_BUF_STATE_QUEUED).  Jump to that label directly: the intermediate
err_pm_put / err_media_pipeline_stop labels are skipped, which is
correct because nothing they would undo has happened yet.

This mirrors the uvcvideo fix in commit 4cf3b6fd54eb ("media: uvcvideo:
Return queued buffers on start_streaming() failure").

Subject: [PATCH 0872/5214] PCI: loongson: Do not ignore downstream devices on
 external bridges

Loongson PCI host controllers have a hardware quirk that requires
software to ignore downstream devices with device number > 0 on the
internal bridges. The current implementation applies the workaround to
all non-root buses, which breaks external bridges (e.g., PCIe switches)
with multiple downstream devices.

Fix it by only applying the workaround to internal bridges.

Tested on Loongson-LS3A4000-7A1000-NUC-SE, using AMD Promontory 21
chipset add-in card [1].

When an MHI device uses standard MSI, the PCI core requires the allocated
number of vectors to be a strict power of two. But devices will only ask
for the irqs they need, so they might not be properly aligned.

Make sure a power-of-2 number of vectors is requested.

Subject: [PATCH 0875/5214] bus: mhi: ep: Fix potential deadlock in
 mhi_ep_reset_worker()

There is a potential deadlock scenario in mhi_ep_reset_worker() where
the state_lock mutex is acquired twice in the same call chain:

mhi_ep_reset_worker()
  mutex_lock(&mhi_cntrl->state_lock)
    mhi_ep_power_up()
      mhi_ep_set_ready_state()
        mutex_lock(&mhi_cntrl->state_lock)  <- Deadlock

Fix this by releasing the state_lock before calling mhi_ep_power_up().
The lock is only needed to protect current MHI state read operation. The
lock can be safely released before proceeding with the power up sequence.

Subject: [PATCH 0876/5214] bus: mhi: ep: Add missing state_lock protection for
 mhi_state access

The mhi_cntrl->mhi_state field should be protected by state_lock to
ensure atomic state transitions. However, mhi_ep_power_up() access
mhi_state without holding this lock, which can race with concurrent state
transitions and lead to state corruption.

Add proper state_lock protection around mhi_state access.

All the callers of mhi_ep_handle_syserr() except mhi_ep_process_cmd_ring()
are holding the 'state_lock' to avoid the race in setting the MHI state. So
do the same in mhi_ep_process_cmd_ring() for sanity.

Subject: [PATCH 0879/5214] coresight: fix missing error code when trace ID is
 invalid

When coresight_path_assign_trace_id() cannot assign a valid trace ID,
coresight_enable_sysfs() takes the err_path goto with ret still 0,
returning success to the caller despite no trace session being started.

Change coresight_path_assign_trace_id() to return int, moving the
IS_VALID_CS_TRACE_ID() check inside it so it returns -EINVAL on failure
and 0 on success. Update both callers to propagate this return value
directly instead of inspecting path->trace_id after the call.

Subject: [PATCH 0884/5214] clk: qcom: cmnpll: Account for reference clock
 divider

The clk_cmn_pll_recalc_rate() function must account for the reference clock
divider programmed in CMN_PLL_REFCLK_CONFIG. Without this fix, platforms
with a reference divider other than 1 calculate incorrect CMN PLL rates.
For example, on IPQ5332 where the reference divider is 2, the computed rate
becomes twice the actual output.

Read CMN_PLL_REFCLK_DIV and divide the parent rate by this value before
applying the 2 * FACTOR scaling. This yields the correct rate calculation:
rate = (parent_rate / ref_div) * 2 * factor.

Maintain backward compatibility with earlier platforms (e.g. IPQ9574,
IPQ5424, IPQ5018) that use ref_div = 1.

Subject: [PATCH 0885/5214] clk: qcom: cmnpll: Add IPQ5332 SoC support

The CMN PLL in IPQ5332 SoC produces different output clocks when compared
to IPQ9574. While most clock outputs match IPQ9574, the ethernet PHY/switch
(50 Mhz) and PPE clocks (200 Mhz) in IPQ5332 are different.

Add IPQ5332-specific clock definitions and of_device_id entry.

Subject: [PATCH 0886/5214] dt-bindings: clock: qcom,sm6125-dispcc: reference
 qcom,gcc.yaml

Just like most of Qualcomm clock controllers, we can reference common
qcom,gcc.yaml schema to unify the common parts of the binding. This
also adds the '#reset-cells' property which is permitted for the
SM6125 SoC clock controllers, but not listed as a valid property.

Subject: [PATCH 0887/5214] PCI: dwc: Apply ECRC workaround for DesignWare
 cores prior to 5.10a

The ECRC (TLP digest) workaround was originally applied only for DesignWare
core version 4.90a. Per discussion in Synopsys case, the dependency of the
iATU TD bit on ECRC generation was removed in 5.10a, so apply the
workaround for all DWC versions below that release.

Replace the misleading comment that referred to raw version constants
with readable DesignWare release name to help readability.

Subject: [PATCH 0888/5214] clk: rockchip: allow COMPILE_TEST builds

COMMON_CLK_ROCKCHIP already gates the Rockchip clock objects inside the
Rockchip clock Makefile.  Allow selecting it for COMPILE_TEST and use it
for the parent Makefile descent instead of ARCH_ROCKCHIP.

The per-SoC Rockchip clock symbols already have COMPILE_TEST dependencies,
so this exposes the existing build coverage to other architectures without
selecting the Rockchip platform.

Tested with:
make LLVM=1 ARCH=loongarch drivers/clk/rockchip/

Check that the algo parameter passed to calc_file_id_hash is within valid
range. Do this in asymmetric_verify_v3 since this value will also be passed
to a hashless signature verification function from here.

Subject: [PATCH 0893/5214] integrity: Refactor asymmetric_verify for
 reusability

Refactor asymmetric_verify for reusability. Have it call
asymmetric_verify_common with the signature verification key and the
public_key structure as parameters. sigv3 support for ML-DSA will need to
check the public key type first to decide how to do the signature
verification and therefore will have these parameters available for
calling asymmetric_verify_common.

Subject: [PATCH 0894/5214] integrity: Add support for sigv3 verification using
 ML-DSA keys

Add support for sigv3 signature verification using ML-DSA in pure mode.
When a sigv3 signature is verified, first check whether the key to use
for verification is an ML-DSA key and therefore uses a hashless signature
verification scheme. The hashless signature verification method uses the
ima_file_id structure directly for signature verification rather than
its digest.

Subject: [PATCH 0895/5214] evm: terminate and bound the evm_xattrs read buffer

evm_read_xattrs() allocates size + 1 bytes, fills them from the list of
enabled xattrs, and then passes strlen(temp) to
simple_read_from_buffer(). When no configured xattrs are enabled, the
fill loop stores nothing and temp[0] remains uninitialized, so strlen()
reads beyond initialized memory.

Explicitly terminate the buffer after allocation, use snprintf() for
each formatted line, and pass the accumulated length, without risk of
truncation, to simple_read_from_buffer().

During resume, qcom_pcie_icc_opp_update() may access DBI registers before
the OPP votes are restored, triggering NoC errors.

Set the PCIe controller to the maximum OPP first in resume_noirq(), then
proceed with link/DBI accesses. The OPP is later updated again based on
the actual link bandwidth requirements.

Introduce a helper to reuse the max-OPP setup code and share it with
probe().

Subject: [PATCH 0897/5214] KVM: x86: Add dedicated storage for guest RIP

Add kvm_vcpu_arch.rip to track guest RIP instead of including it in the
generic regs[] array.  Decoupling RIP from regs[] will allow using a
*completely* arbitrary index for RIP, as opposed to the mostly-arbitrary
index that is currently used.  That in turn will allow using indices
16-31 to track R16-R31 that are coming with APX.

Note, although RIP can used for addressing, it does NOT have an
architecturally defined index, and so can't be reached via flows like
get_vmx_mem_address() where KVM "blindly" reads a general purpose register
given the SIB information reported by hardware.  For RIP-relative
addressing, hardware reports the full "offset" in vmcs.EXIT_QUALIFICATION.

Note #2, keep the available/dirty tracking as RSP is context switched
through the VMCS, i.e. needs to be cached for VMX.

Opportunistically rename NR_VCPU_REGS to NR_VCPU_GENERAL_PURPOSE_REGS to
better capture what it tracks, and so that KVM can slot in R16-R13 without
running into weirdness where KVM's definition of "EXREG" doesn't line up
with APX's definition of "extended reg".

No functional change intended.

From: Sean Christopherson <seanjc@google.com>

Subject: [PATCH 0898/5214] KVM: x86: Drop the "EX" part of "EXREG" to avoid
 collision with APX
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that NR_VCPU_REGS is no longer a thing, and now that now that RIP is
effectively an EXREG, drop the "EX" is for extended (or maybe extra?")
prefix from non-GPR registers to avoid a collision with APX (Advanced
Performance Extensions), which adds:

  16 additional general-purpose registers (GPRs) R16–R31, also referred
  to as Extended GPRs (EGPRs)  in this document;

I.e. KVM's version of "extended" won't match with APX's definition.

No functional change intended.

Subject: [PATCH 0899/5214] KVM: nVMX: Do a bitwise-AND of regs_avail when
 switching active VMCS

When switching between vmcs01 and vmcs02, do a bitwise-AND of regs_avail
to effectively reset the mask for the new VMCS, purely to be consistent
with all other "full" writes of regs_avail.  In practice, a straight write
versus a bitwise-AND will yield the same result, as kvm_arch_vcpu_create()
marks *all* registers available (and dirty), and KVM never marks registers
unavailable unless they're lazily loaded.

This will allow adding wrapper APIs to set regs_{avail,dirty} without
having to add special handling for a nVMX use case that doesn't exist in
practice.

Subject: [PATCH 0900/5214] KVM: x86: Add wrapper APIs to reset dirty/available
 register masks

Add wrappers for setting regs_{avail,dirty} in anticipation of turning the
fields into proper bitmaps, at which point direct writes won't work so
well.

Deliberately leave the initialization in kvm_arch_vcpu_create() as-is,
because the regs_avail logic in particular is special in that it's the one
and only place where KVM marks eagerly synchronized registers as available.

No functional change intended.

Subject: [PATCH 0901/5214] KVM: x86: Track available/dirty register masks as
 "unsigned long" values

Convert regs_{avail,dirty} and all related masks to "unsigned long" values
as an intermediate step towards declaring the fields as actual bitmaps, and
as a step toward support APX, which will push the total number of registers
beyond 32 on 64-bit kernels.

Opportunistically convert TDX's ULL bitmask to a UL to match everything
else (TDX is 64-bit only, so it's a nop in the end).

No functional change intended.

Subject: [PATCH 0902/5214] KVM: x86: Use a proper bitmap for tracking
 available/dirty registers

Define regs_{avail,dirty} as bitmaps instead of U32s to harden against
overflow, and to allow for dynamically sizing the bitmaps when APX comes
along, which will add 16 more GPRs (R16-R31) and thus increase the total
number of registers beyond 32.

Open code writes in the "reset" APIs, as the writes are hot paths and
bitmap_write() is complete overkill for what KVM needs.  Even better,
hardcoding writes to entry '0' in the array is a perfect excuse to assert
that the array contains exactly one entry, e.g. to effectively add guard
against defining R16-R31 in 32-bit kernels.

For all intents and purposes, no functional change intended even though
using bitmap_fill() will mean "undefined" registers are no longer marked
available and dirty (KVM should never be querying those bits).

Subject: [PATCH 0910/5214] KVM: Rename invalidate_begin to invalidate_start
 for consistency

Rename kvm_mmu_invalidate_begin() to kvm_mmu_invalidate_start() to
align with mmu_notifier_ops.invalidate_range_start(), which is the
callback that ultimately drives KVM's MMU invalidation.

While the naming within KVM itself is a close split between "_begin" and
"_start":

  $ git grep -E "invalidate(_range)?_begin" **/kvm* | wc -l
  12
  $ git grep -E "invalidate(_range)?_start" **/kvm* | wc -l
  21

All two of the begin() uses are in KVM:

  $ git grep -E "invalidate(_range)?_begin" * | wc -l
  14

And those two holdouts are bugs in invalidate_range_start()'s comment,
i.e. will also be fixed sooner or later[*].  On the other hand, use of
_start() is pervasive throughout the kernel:

  $ git grep -E "invalidate(_range)?_start" * | wc -l
  117

Even if that weren't the case, conforming to the mmu_notifier_ops naming
is the right call since invalidate_range_start() is the external API that
KVM hooks into.

No functional change intended.

Subject: [PATCH 0911/5214] KVM: x86: Ensure vendor's exit handler runs before
 fastpath userspace exits

Move the handling of fastpath userspace exits into vendor code to ensure
KVM runs vendor specific operations that need to run before userspace gains
control of the vCPU.  E.g. for VMX (and soon to be for SVM as well), KVM
needs to flush the PML buffer prior to exiting to userspace, otherwise any
memory written by the final KVM_RUN might never be flagged as dirty.

Note, waiting to snapshot CR0 and CR3 until svm_handle_exit() is flawed in
general, as that risks consuming stale state in a fastpath handler.  That
will be addressed in a future change.

Fixes: f7f39c50edb9 ("KVM: x86: Exit to userspace if fastpath triggers one on instruction skip")

Subject: [PATCH 0912/5214] KVM: SVM: Refresh vcpu->arch.cr{0,3} prior to
 invoking fastpath handler

Refresh KVM's copies of CR0 and CR3 from the VMCB prior to (potentially)
invoking a fastpath handler to ensure that KVM doesn't consume stale
state.  While it's unlikely KVM will ever consume CR3 or CR0.{TS,MP} in
the fastpath, grabbing the values from the VMCB is inexpensive, i.e. the
risk of subtle bugs far outweighs the reward of deferring reads for a
small subset of VM-Exits.

Note, KVM doesn't currently consume CR3 or CR0.{TS,MP} in the fastpath,
as KVM requires next_rip to be valid (i.e. KVM doesn't read CR3 to decode
the instruction), CR0.MP is never consumed, and CR0.TS is only consumed by
the full emulator.

Subject: [PATCH 0917/5214] crypto/ccp: export firmware supported vm types

In some configurations, the firmware does not support all VM types. The SEV
firmware has an entry in the TCB_VERSION structure referred to as the
Security Version Number in the SEV-SNP firmware specification and referred
to as the "SPL" in SEV firmware release notes. The SEV firmware release
notes say:

    On every SEV firmware release where a security mitigation has been
    added, the SNP SPL gets increased by 1. This is to let users know that
    it is important to update to this version.

The SEV firmware release that fixed CVE-2025-48514 by disabling SEV-ES
support on vulnerable platforms has this SVN increased to reflect the fix.
The SVN is platform-specific, as is the structure of TCB_VERSION.

Check CURRENT_TCB instead of REPORTED_TCB, since the firmware behaves with
the CURRENT_TCB SVN level and will reject SEV-ES VMs accordingly.

Parse the SVN, and mask off the SEV_ES supported VM type from the list of
supported types if it is above the per-platform threshold for the relevant
platforms.

Subject: [PATCH 0920/5214] KVM: SEV: Don't advertise support for unusable VM
 types

Commit 0aa6b90ef9d7 ("KVM: SVM: Add support for allowing zero SEV ASIDs")
made it possible to make it impossible to use SEV VMs by not allocating
them any ASIDs.

Commit 6c7c620585c6 ("KVM: SEV: Add SEV-SNP CipherTextHiding support") did
the same thing for SEV-ES.

Do not export KVM_X86_SEV(_ES)_VM as supported types if in either of these
situations, so that userspace can use them to determine what is actually
supported by the current kernel configuration.

Also move the buildup to a local variable so it is easier to add additional
masking in future patches.

Subject: [PATCH 0921/5214] KVM: SEV: Don't advertise VM types that are
 disabled by firmware

As called out in a footnote for a recent SNP vulnerability[1], it is
possible for a specific flavor of SEV+ to be disabled by the firmware even
when the flavor is fully supported by the CPU and platform:

  Applying mitigation CVE-2025-48514 will result in disabling SEV-ES when
  SEV-SNP is enabled.

Restrict KVM's set of supported VM types based on the VM types that are
fully supported by firmware to avoid over-reporting what KVM can actually
support.  Like KVM's handling of ASID space exhaustion, don't modify KVM's
CPUID capabilities, as the CPU/platform still supports the underlying
technology and clearing e.g. SEV_ES while advertising SEV_SNP would confuse
KVM and userspace.

Subject: [PATCH 0923/5214] KVM: SVM: Fix page overflow in sev_dbg_crypt() for
 ENCRYPT path

In sev_dbg_crypt(), the per-iteration transfer length is bounded by
the source page offset (PAGE_SIZE - s_off) but not by the destination
page offset (PAGE_SIZE - d_off).  When d_off > s_off, the encrypt
path (__sev_dbg_encrypt_user) performs a read-modify-write using a
single-page intermediate buffer (dst_tpage):

  1. __sev_dbg_decrypt() expands the size to round_up(len + (d_off & 15), 16)
     before issuing the PSP command.  If len + (d_off & 15) > PAGE_SIZE,
     the PSP writes beyond the end of the 4096-byte dst_tpage allocation.

  2. The subsequent memcpy()/copy_from_user() into
     page_address(dst_tpage) + (d_off & 15) of 'len' bytes overflows
     by up to 15 bytes under the same condition.

Trigger example: s_off = 0, d_off = 1, debug.len = PAGE_SIZE -
the PSP is instructed to write round_up(4097, 16) = 4112 bytes to
a 4096-byte buffer.

Fix by also bounding len by (PAGE_SIZE - d_off), the same check that
sev_send_update_data() already performs for its single-page guest
region.

Subject: [PATCH 0924/5214] KVM: Fix kvm_vcpu_map[_readonly]() function
 prototypes

kvm_vcpu_map() and kvm_vcpu_map_readonly() should take a gfn instead of
a gpa. This appears to be a result of the original kvm_vcpu_map() being
declared with the wrong function prototype in kvm_host.h, even though
it was correct in the actual implementation in kvm_main.c.

No actual harm has been done yet as all of the call sites are correctly
passing in a gfn. Plus, both gfn_t and gpa_t are typedef'd to u64 so
this change shouldn't have any functional impact.

Compile-tested on x86 and ppc, which are the current users of these
interfaces.

Subject: [PATCH 0925/5214] KVM: x86: Don't leave APF half-enabled on bad APF
 data GPA

kvm_pv_enable_async_pf() updates vcpu->arch.apf.msr_en_val before
initializing the APF data gfn_to_hva cache. If userspace provides an
invalid GPA, kvm_gfn_to_hva_cache_init() fails, but msr_en_val stays
enabled and leaves APF state half-initialized.

Later APF paths can then try to use the empty cache and trigger
WARN_ON() in kvm_read_guest_offset_cached().

Determine the new APF enabled state from the incoming MSR value, do cache
initialization first on the enable path, and commit msr_en_val only after
successful initialization. Keep the disable path behavior unchanged.

 KVM_ASYNC_PF_DELIVERY_AS_PF_VMEXIT

Drop kvm_vcpu_arch.apf.delivery_as_pf_vmexit and instead use msr_en_val as
the source of truth to reduce the probability of operating on stale data.
This fixes flaws where KVM fails to update delivery_as_pf_vmexit when APF
is explicitly disabled by the guest or implicitly disabled by KVM on INIT.
Absent other bugs, the flaws are benign as KVM *shouldn't* consume
delivery_as_pf_vmexit when PV APF support is disabled.

Simply delete the field, as there's zero benefit to maintaining a separate
"cache" of the state.

e.g. so that it's more obvious that both paths are "success" paths.

 timeout configurable

When memslot_perf_test is run on the Qemu Risc-V Virt machine,
sometimes the RW subtest fails due to sigalarm, indicating that the
guest sync did not finish within the expected duration of 10 seconds.
Since the current timeout value is itself a bump up from the original
2s, making the host timeout value configurable via a new command line
parameter. The test can be invoked with '-t' option to set a suitable
timeout value for the host.

 kvm_vfio_file_set_spapr_tce()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use a mutex guard to hold a lock for the entirety of the function, which
removes the need for a goto (whose label even has a misleading name
since 8152f8201088 ("fdget(), more trivial conversions"))

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are two callsites which destroy files in kv->file_list: the
function servicing KVM_DEV_VFIO_FILE_DEL, and the relase of the whole
KVM VFIO device. The process involves several steps, so move all those
into a single function, removing duplicate code.

Subject: [PATCH 0932/5214] KVM: VFIO: update coherency only if file was
 deleted
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When servicing a KVM_DEV_VFIO_FILE_DEL request, if a file is removed
from kv->file_list, kv->noncoherent needs to be updated, in case we
can revert to using coherent DMA. However, if we found no candidate
to remove, there is no need to re-scan the list, so do it only if a
matching file was found.

To simplify the control flow, use a mutex guard so that we can return
early from within the search loop if the maching file is found.

Subject: [PATCH 0933/5214] x86/tdx: Use pg_level in TDX APIs, not the
 TDX-Module's 0-based level

Rework the TDX APIs to take the kernel's 1-based pg_level enum, not the
TDX-Module's 0-based level.  The APIs are _kernel_ APIs, not TDX-Module
APIs, and the kernel (and KVM) uses "enum pg_level" literally everywhere.

Using "enum pg_level" eliminates ambiguity when looking at the APIs (it's
NOT clear that "int level" refers to the TDX-Module's level), and will
allow for using existing helpers like page_level_size() when support for
hugepages is added to the S-EPT APIs.

No functional change intended.

Subject: [PATCH 0934/5214] KVM: x86/mmu: Update iter->old_spte if cmpxchg64 on
 mirror SPTE "fails"

Pass a pointer to iter->old_spte, not simply its value, when setting an
external SPTE in __tdp_mmu_set_spte_atomic(), so that the iterator's value
will be updated if the cmpxchg64 to freeze the mirror SPTE fails.  The bug

Subject: [PATCH 0935/5214] KVM: TDX: Account all non-transient page
 allocations for per-TD structures

Account all non-transient allocations associated with a single TD (or its
vCPUs), as KVM's ABI is that allocations that are active for the lifetime
of a VM are accounted.  Leave temporary allocations, i.e. allocations that
are freed within a single function/ioctl, unaccounted, to again align with
KVM's existing behavior, e.g. see commit dd103407ca31 ("KVM: X86: Remove
unnecessary GFP_KERNEL_ACCOUNT for temporary variables").

Subject: [PATCH 0937/5214] KVM: TDX: Fix x2APIC MSR handling in
 tdx_has_emulated_msr()

Rework tdx_has_emulated_msr() to explicitly enumerate the x2APIC MSRs
that KVM can emulate, instead of trying to enumerate the MSRs that KVM
cannot emulate. Drop the inner switch and list the emulatable x2APIC
registers directly in the outer switch's "return true" block.

The old code had multiple bugs in the x2APIC range handling.
X2APIC_MSR(APIC_ISR + APIC_ISR_NR) was incorrect because APIC_ISR_NR is
0x8, not 0x80, so the X2APIC_MSR() shift lost the lower bits, collapsing
each range to a single MSR. IA32_X2APIC_SELF_IPI was also missing from
the non-emulatable list.  Note, these bugs are relatively benign, as they
only affect a guest that is requesting "bogus" emulation.

KVM has no visibility into whether or not a guest has enabled #VE
reduction, which changes which MSRs the TDX-Module handles itself versus
triggering a #VE for the guest to make a TDVMCALL. So maintaining a list
of non-emulatable MSRs is fragile. Listing only the MSRs KVM can always
emulate sidesteps the problem.

Subject: [PATCH 0938/5214] KVM: selftests: Add a test to verify SEV
 {en,de}crypt debug ioctls

Add a selftest to verify KVM's handling of {de,en}crypt debug ioctls,
specifically focusing on edge cases around the chunk (16 bytes) and page
(4096) sizes, where KVM had multiple bugs.  E.g. KVM would fail to handle
small sizes that aren't naturally aligned and sized, would buffer overflow
if the destination was unaligned but the source was not, etc.

Attempt to strike a balance between an exhaustive test and a reasonable
runtime.  On a system with both SEV and SEV-ES support, the current runtime
is under 45 seconds.  Which isn't great, but it's tolerable, and it's not
obvious which of the combinations are "better" than the others.

destination is non-NULL and doesn't wrap instead of subtly relying on
sev_pin_memory() to perform the check.  This will allow adding and using
a more focused single-page pinning helper.

Subject: [PATCH 0940/5214] KVM: SEV: Add helper function to pin/unpin a single
 page

Add helpers to pin/unpin a single page, and use it in all flows that pin
exactly one page.  None of the single-page users actually check that the
correct number of pages was pinned, which is functionally ok, but visually
jarring, especially in the decrypt/encrypt flow, which separately pins two
pages, but uses a single variable to track how pages were pinned each time.
Again, it's functionally ok since core mm guarantees exactly one page will
be pinned on success, but it's ugly.

Opportunistically use page_to_phys() instead of open coding an equivalent
via page_to_pfn().

Note, all users of the single-page helper pre-validate the address and
length, i.e. don't rely on the sanity check in sev_pin_memory().

No functional change intended.

Subject: [PATCH 0941/5214] KVM: SEV: Rewrite logic to {de,en}crypt memory for
 debug

Wholesale rewrite the guts of the debug {de,en}crypt flows, as the existing
code is broken, e.g. doesn't handle cases where the access isn't naturally
sized and aligned, and is so wildly flawed that attempting to salvage the
current code in an iterative fashion would be more risky than a rewrite.

E.g. when encrypting 9 bytes at offset 8, KVM needs to _decrypt_
destination[31:0] into a temporary buffer, buffer[31:0], then copy 9 bytes
from source[8:0] to buffer[16:8], then encrypt buffer[31:0] back into
destination[31:0].  The current code only ever copies 16 bytes, and
bizarrely uses a temporary buffer for the source as well.

To keep the code easier to read and maintain, send the unaligned cases
down dedicated "slow" paths instead of trying to mix and match the possible
combinations in one helper.

For now, preserve the basic approach of the current code, e.g. allocate an
entire page for the temporary buffer, to minimize unwanted changes in
functionality.

Subject: [PATCH 0942/5214] KVM: SEV: Allocate only as many bytes as needed for
 temp crypt buffers

When using a temporary buffer to {de,en}crypt unaligned memory for debug,
allocate only the number of bytes that are needed instead of allocating an
entire page.  The most common case for unaligned accesses will be reading
or writing less than 16 bytes.

Subject: [PATCH 0943/5214] KVM: x86: Define
 KVM_X86_QUIRK_NESTED_SVM_SHARED_PAT

Define a quirk to control whether nested SVM shares L1's PAT with L2
(legacy behavior) or gives L2 its own independent gPAT (correct behavior
per the APM).

When the quirk is enabled (default), L2 shares L1's PAT, preserving the
legacy KVM behavior. When userspace disables the quirk, KVM correctly
virtualizes the PAT for nested SVM guests, giving L2 a separate gPAT as
specified in the AMD architecture.

Subject: [PATCH 0944/5214] KVM: x86: nSVM: Clear VMCB_NPT clean bit when
 updating hPAT from guest mode

When running an L2 guest and writing to MSR_IA32_CR_PAT, the host PAT value
is stored in both vmcb01's g_pat field and vmcb02's g_pat field, but the
clean bit was only being cleared for vmcb02.

Introduce the helper vmcb_set_gpat() which sets vmcb->save.g_pat and marks
the VMCB dirty for VMCB_NPT. Use this helper in both svm_set_msr() for
updating vmcb01 and in nested_vmcb02_compute_g_pat() for updating vmcb02,
ensuring both VMCBs' NPT fields are properly marked dirty.

Subject: [PATCH 0946/5214] KVM: x86: nSVM: Set vmcb02.g_pat correctly for
 nested NPT

When KVM_X86_QUIRK_NESTED_SVM_SHARED_PAT is disabled and nested NPT is
enabled in vmcb12, copy the (cached and validated) vmcb12 g_pat field to
vmcb02's g_pat, giving L2 its own independent guest PAT register.

When the quirk is enabled (default), or when NPT is enabled but nested NPT
is disabled, copy L1's IA32_PAT MSR to the vmcb02 g_pat field, since L2
shares the IA32_PAT MSR with L1.

When NPT is disabled, the g_pat field is ignored by hardware.

Subject: [PATCH 0947/5214] KVM: x86: nSVM: Redirect IA32_PAT accesses to
 either hPAT or gPAT

When handling PAT accesses from L2, route PAT accesses to either hPAT or
gPAT based on whether or not L2 has a separate PAT, i.e. if KVM is actually
emulating gPAT, instead of using L1's PAT for everything.  Specifically, if
KVM_X86_QUIRK_NESTED_SVM_SHARED_PAT is disabled, the vCPU is in guest mode
with nested NPT enabled, *and* the access if from the guest (i.e. is not
from the host stuffing PAT as part of save/restore), then redirect guest
PAT accesses to the gPAT "register" in vmcb02, i.e. emulate gPAT for L2.

Always route non-guest accesses to hPAT, i.e. L1's PAT in vcpu->arch.pat,
to ensures that KVM_{G,S}ET_MSRS and KVM_{G,S}ET_NESTED_STATE are
independent of each other and can be ordered arbitrarily during save and
restore.  E.g. if KVM didn't exempt host accesses, then whether a write to
PAT hit hPAT or gPAT would vary based on whether userspace restores PAT
before or after nested state.  Note, gPAT is saved and restored separately
via KVM_{G,S}ET_NESTED_STATE.

WARN if there's a host-initiated access to PAT from within KVM_RUN, i.e. if
KVM itself initiated the access, as there are no such accesses today, and
it's not clear what the "right" behavior would be.

According to the APM volume 3 pseudo-code for "VMRUN," when nested paging
is enabled in the vmcb, the guest PAT register (gPAT) is saved to the vmcb
on emulated VMEXIT.

When KVM_X86_QUIRK_NESTED_SVM_SHARED_PAT is disabled and the vCPU is in
guest mode with nested NPT enabled, save the vmcb02 g_pat field to the
vmcb12 g_pat field on emulated VMEXIT.

Subject: [PATCH 0950/5214] KVM: x86: nSVM: Save/restore gPAT with
 KVM_{GET,SET}_NESTED_STATE

Add a 'gpat' field to kvm_svm_nested_state_hdr to carry L2's guest PAT
value across save and restore.

When KVM_X86_QUIRK_NESTED_SVM_SHARED_PAT is disabled and the vCPU is in
guest mode with nested NPT enabled, save vmcb02's g_pat into the header on
KVM_GET_NESTED_STATE, and restore it on KVM_SET_NESTED_STATE.

Host-initiated accesses to IA32_PAT (via KVM_GET/SET_MSRS) always target
L1's hPAT, so they cannot be used to save or restore gPAT. The separate
header field ensures that KVM_GET/SET_MSRS and KVM_GET/SET_NESTED_STATE are
independent and can be ordered arbitrarily during save and restore.

Note that struct kvm_svm_nested_state_hdr is included in a union padded to
120 bytes, so there is room to add the gpat field without changing any
offsets.

 trigger to pm suspend

Mark all open DAI runtimes as suspended in the component .suspend
callback instead of relying on SNDRV_PCM_TRIGGER_SUSPEND, which is
not delivered during PAUSE or xrun states.

If during system suspend a dai is open it means that it is in either in
SUSPENDED, PAUSED or STOPPED  (due to xrun) state and they will need to be
re-initialized during resume (which is done in .prepare callback).

Subject: [PATCH 0953/5214] dt-bindings: phy: lynx-28g: add compatible strings
 per SerDes and instantiation

The 28G Lynx SerDes is instantiated 3 times in the NXP LX2160A SoC and
twice in the NXP LX2162A. All these instances share the same register
map, but the number of lanes and the protocols supported by each lane
differs in a way that isn't detectable by the programming model.

For example, not all lanes of all SerDes block instantiations support
25GbE.

So, using a generic "fsl,lynx-28g" compatible string and expecting all
SerDes instantiations to use it was a mistake that needs to be fixed.

The option chosen is to encode the SoC and the SerDes instance in the
compatible string, with everything else being the responsibility of the
driver to derive.

An alternative considered but dismissed was to add sufficient device
tree properties to describe the per-lane differences (implying:
supported protocols), as well as the different lane count.

Any decision made for the 28G Lynx should be consistent with the
decisions taken for the yet-to-be-introduced 10G Lynx SerDes (older
generation for older SoCs), because of how similar they are.

I've seen the alternative at play in this unmerged patch set for the 10G
Lynx here, and I didn't like it:
https://lore.kernel.org/linux-phy/20230413160607.4128315-3-sean.anderson@seco.com/

This is because there, we have a higher degree of variability in the
PCCR register values that need to be written per protocol. This makes
that approach more drawn-out and more prone to errors, compared to the
compatible strings which are more succinct and obviously correct.

NXP SoC reference manuals clearly document the SerDes instantiations as
not identical, and refers to them as such (SerDes 1, 2, etc).

The per-SoC compatible string is prepended to the "fsl,lynx-28g" generic
compatible, which is left there for compatibility with old kernels. An
exception would be LX2160A SerDes #3, which at the time of writing is
not described in fsl-lx2160a.dtsi. As "fsl,lx2160a-serdes3" implies it
is a 28G Lynx SerDes, it makes "fsl,lynx-28g" redundant so we don't
accept it.

 LX2162A lane indices

The SerDes 1 of LX2162A has fewer lanes than all other instances, and
strangely, their indices are not 0-3, but 4-7.

This is a best-effort constraint, since we can only impose it when using
per-SoC compatible string and per-lane OF nodes.

Subject: [PATCH 0955/5214] phy: lynx-28g: require an OF node to probe

The driver will gain support for variants in an upcoming change, and
will use of_device_get_match_data() to deduce the running variant from
the compatible string.

Currently, the driver expects the schema at phy/fsl,lynx-28g.yaml, and
OF-based consumers, but doesn't enforce this. And it is possible for
user space to force-bind the driver to a device without OF node using
the driver_override sysfs.

To avoid future surprise crashes for an unsupported configuration,
explicitly test for the presence of an OF node and fail probing if
found.

Subject: [PATCH 0956/5214] phy: lynx-28g: probe on per-SoC and per-instance
 compatible strings

Add driver support for probing on the new, per-instance and per-SoC
bindings, which provide the main benefit that they allow rejecting
unsupported protocols per lane (10GbE on SerDes 2 lanes 0-5), but they
also allow avoiding the creation of PHYs for lanes that don't exist
(LX2162A lanes 0-3).

For old device trees with just "fsl,lynx-28g", the only things that
change are:

- a probe time warning/encouragement to update the device tree. This is
  warranted by the fact that using "fsl,lynx-28g" may already provide
  incorrect behaviour (undetected absent 10GbE support on LX2160A
  SerDes 2 lanes 0-5). But we retain bug compatibility nonetheless.

- the feature set is frozen in time (e.g. no 25GbE). Since we cannot
  guarantee that this protocol will work on a lane, just err on the safe
  side and don't offer it (and require a device tree update to get it).

In terms of code, the lynx_28g_supports_lane_mode() function prototype
changes. It was a SerDes-global function and now becomes per lane, to
reflect the specific capabilities each instance may have. The
implementation goes through priv->info->lane_supports_mode().

Subject: [PATCH 0957/5214] phy: lynx-28g: add support for 25GBASER

Add support for 25GBASE-R in the Lynx 28G SerDes PHY driver. This will
be used by the dpaa2-mac consumer on LX2160A with:
- phy_validate(phy, PHY_MODE_ETHERNET, PHY_INTERFACE_MODE_25GBASER) to
  detect support.
- phy_set_mode_ext(phy, PHY_MODE_ETHERNET, PHY_INTERFACE_MODE_25GBASER)
  to reconfigure the lane for this protocol.

The intended use case for dynamic protocol switching to 25GBase-R is
with SFP28 modules, and protocol switching is triggered by the SFP
module insertion. There also exists a 25GBase-KR use case, where the
protocol switching is covered by IEEE 802.3 clause 73 auto-negotiation.
However, that is not handled here; it merely needs the support added
here as basic ground work.

The lane frequency for 25GbE is sourced from a clock net frequency of
12.890625 GHz, as produced by PLLF or PLLS, further multiplied by the
lane by 2. The clock net frequencies produced by the PLLs are treated as
read-only by the driver, so the absence of a PLL provisioned for the
right clock net frequency implies absence of 25GbE support, even though
a lane might have the appropriate protocol converter for it.

In terms of implementation, the change consists of:
- determining at probe time if any PLL was preconfigured for the
  required clock net frequency for 25GbE
- adding the default lane parameters for reconfiguring a lane to 25GbE
  irrespective of the original protocol
- allowing this operating mode only on supported lanes, i.e. all lanes
  of LX2162A SerDes #1, and LX2160A SerDes lanes 0-1, 4-7.

Subject: [PATCH 0958/5214] phy: phy-can-transceiver: Check driver match and
 driver data against NULL

Every platform driver can be forced to match a device that doesn't
match its list of device IDs because of device_match_driver_override()
so platform drivers that rely on the existence of a device's driver
data need to verify its presence.

Accordingly, add requisite match and driver data checks against NULL
to the driver where they are missing.

Subject: [PATCH 0960/5214] phy: phy-can-transceiver: Move OF ID table closer
 to their user

There is no code that uses ID table directly, except the
struct device_driver at the end of the file. Hence, move
table closer to its user. It's always possible to access
them via a pointer.

Subject: [PATCH 0961/5214] phy: phy-can-transceiver: Don't check for specific
 errors when parsing properties

Instead of checking for the specific error codes (that can be considered
a layering violation to some extent) check for the property existence first
and then either parse it, or apply a default value.

With that, return an error when parsing of the existing property fails.

Subject: [PATCH 0962/5214] phy: phy-can-transceiver: Decouple assignment and
 definition in probe

The code like

	int foo = X;
	...
	if (bar)
		foo = Y;

is prone to subtle mistakes and hence harder to maintain as the foo value
may be changed inadvertently while code in '...' grown in lines. On top
it's harder to navigate to understand the possible values of foo when branch
is not taken (requires to look somewhere else in the code, far from the piece
at hand).

Besides that in case of taken branch the foo will be rewritten, which is
not a problem per se, just an unneeded operation.

Decouple assignment and definition to use if-else to address the inconveniences
described above.

Subject: [PATCH 0964/5214] dt-bindings: phy: rockchip,inno-usb2phy: Require
 GRF for RK3568/RV1108

Typically these Rockchip USB2 PHYs are fully contained within a single
GRF. However, for RK3568 and RV1108 regs to control the USB2 PHY is
located in a different GRF compared to the base address.

Update this binding to require rockchip,usbgrf for RK3568 and RV1108 to
properly reflect that the USB GRF is required to control the USB2 PHYs
on these variants. Also disable use of rockchip,usbgrf for variants
where it is not required.

This should not introduce any breakage as the affected usb2phy nodes for
RK3568 and RV1108 were added together with a rockchip,usbgrf phandle in
their initial commit.

Subject: [PATCH 0965/5214] phy: rockchip: inno-usb2: Simplify rockchip,usbgrf
 handling

The logic to decide if usbgrf or grf should be used is more complex than
it needs to be. For RK3568, RV1108 and soon RK3528 we can assign the
rockchip,usbgrf regmap directly to grf instead of doing a usbgrf and grf
dance.

Simplify the code to only use the grf regmap and handle the logic of
what regmap should be used in driver probe instead.

The only expected change from this is that RK3528 can be supported
because of an addition of a of_property_present() check.

Subject: [PATCH 0966/5214] dt-bindings: phy: rockchip,inno-usb2phy: Add
 compatible for RK3528

The embedded USB2 PHY on RK3528 is very similar to the one in RK3568,
the main difference being that it only uses two clocks instead of three.

Add compatible to support the USB2 PHY in RK3528.

The 480m clk is controlled using regs in the PHY address space and not
in the USB GRF address space on e.g. RK3528 and RK3506.

Add a clkout_ctl_phy usb2phy_reg to handle enable/disable of the 480m
clk on these SoCs.

Subject: [PATCH 0968/5214] phy: rockchip: inno-usb2: Add support for RK3528

The RK3528 has a single USB2PHY with a otg and host port.

Add support for the RK3528 variant of USB2PHY.

PHY tuning for RK3528:

- Turn off differential receiver in suspend mode to save power
  consumption.

- Set HS eye-height to 400mV instead of default 450mV.

- Choose the Tx fs/ls data as linestate from TX driver for otg port
  which uses dwc3 controller to improve fs/ls devices compatibility with
  long cables.

Undocumented magic-values are based on the linux-stan-6.1-rkr5 tag of
the vendor-kernel.

Subject: [PATCH 0970/5214] phy: econet: Add PCIe PHY driver for EcoNet
 EN751221 and EN7528 SoCs.

Introduce support for EcoNet PCIe PHY controllers found in EN751221
and EN7528 SoCs, these SoCs are not identical but are similar, each
having one Gen1 port, and one Gen1/Gen2 port.

Also added __counted_by() for extra possible analysis.

Subject: [PATCH 0973/5214] clk: samsung: exynos850: mark APM I3C clocks as
 critical

The Exynos850 APM co-processor relies on the I3C bus to communicate with
the PMIC. Currently, there is no dedicated PMIC consumer driver managing
these clocks, so the clock subsystem automatically gates them during the
initialisation. Once gated, any subsequent ACPM communication with APM
results in timeouts.

As a temporary workaround (and let's hope it doesn't become permanent),
mark both `gout_i3c_pclk` and `gout_i3c_sclk` as CLK_IS_CRITICAL ones to
prevent the clock subsystem from disabling them. This makes the ACPM
communication functional. This workaround should be reverted once a
proper ACPM PMIC driver is implemented to manage these clocks.

Subject: [PATCH 0974/5214] perf record: Refactor ARM64 leaf caller setup out
 of arch

Code in tools/perf/arch causes portability issues/opaqueness and LTO
issues due to the use of weak symbols. Move the adding of LR to the
sample_user_regs into arm64-frame-pointer-unwind-support.c conditional
on EM_HOST == EM_AARCH64 (false on all non-ARM64 builds).

This also better encapsulates the use of the sampled registers by
get_leaf_frame_caller_aarch64 and the set up by the new
add_leaf_frame_caller_opts_aarch64, exposing opportunities for possibly
sampling PC and SP to help the unwinder.

Subject: [PATCH 0975/5214] perf pmu-events AMD: Switch l2_itlb_misses to
 bp_l1_tlb_miss_l2_tlb_miss.all

l2_itlb_misses is a valid legacy cache event name, hence allowing it
in all_events in metric.py. l2_itlb_misses was also a json event for
AMD zen1, zen2 and zen3.

For zen4, zen5 and zen6 the checking that metric events are within the
json was skipping l2_itlb_misses as it is a valid legacy event, however,
the PMU driver lacks the event mapping causing it to be a bad event when
used in the metric.

Add bp_l1_tlb_miss_l2_tlb_miss.all as the l2 itlb miss event (bp =
branch predictor, the AMD way to say itlb), so that is used in
preference to l2_itlb_misses when the event exists.

Remove l2_itlb_misses from metric.py as the legacy event isn't used by
any metrics and having it is error prone for newer AMD zen models.

Fixes: e596f329668ec2b5 ("perf jevents: Add itlb metric group for AMD")

Subject: [PATCH 0976/5214] perf metricgroup: Avoid scanning unnecessary PMUs
 for identifier match

Only uncore PMUs can have an identifier, so add an optimized
perf_pmus__scan routine for that case to avoid all PMU types being
created.

 of pci_device_id array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A list initializer is hard to parse for a human if they don't see or
know the order of the members of struct pci_device_id. So use the
PCI_VDEVICE macro which is much more idiomatic and skip assigning
explicit zeros.

There are no changes to the compiled result of the array; verified with
builds for x86 and arm64.

Subject: [PATCH 0979/5214] scsi: ufs: ufshcd-pci: Use PCI_VDEVICE and named
 initializers for pci array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pci_device_id array uses a mixture of ways to initialize
ufshcd_pci_tbl[]. List initializers are hard to read unless you memoized
the order of the struct members. Use the PCI_VDEVICE for all entries and
a named initializer for .driver_data.

This allows to idiomatically assign the members without using zeros to
fill the fields before .driver_data (either explicitly or hidding in
PCI_VDEVICE()).

There are no changes to the compiled result of the array; verified with
builds for x86 and arm64.

Subject: [PATCH 0982/5214] scsi: scsi_transport_srp: Move long delayed work to
 system_dfl_long_wq
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the code enqueue work items using {queue|mod}_delayed_work(),
using system_long_wq. This workqueue should be used when long works are
expected and it is a per-cpu workqueue.

The function(s) end up calling __queue_delayed_work(), which set a
global timer that could fire anywhere, enqueuing the work where the
timer fired.

Unbound works could benefit from scheduler task placement, to optimize
performance and power consumption. Long work shouldn't stick to a single
CPU.

Recently, a new unbound workqueue specific for long running work has
been added:

    c116737e972e ("workqueue: Add system_dfl_long_wq for long unbound works")

Since the workqueue work doesn't rely on per-cpu variables, there is no
obvious reason that justify the use of a per-cpu workqueue. So change
system_long_wq with system_dfl_long_wq so that the work may benefit from
scheduler task placement.

__LINE__ changes quite easily for cleanup commits. So when checking if a
cleanup patch introduces changes to the resulting binary each usage of
__LINE__ is source of annoyance.

So instead of __FILE__ and __LINE__ emit __func__ to give at least some
more indication about where the messages originates from than __FILE__
alone; with that and the actual message the situation should be clear
enough.

While at it reduce duplication by implementing mv_dprintk() using
mv_printk().

pm8001_store_update_fw() allows a firmware update request even when the

Firmware update is not valid once the controller is in that state, and
attempting it can lead to a call trace. Reject the request early by
checking controller_fatal_error, set the firmware status to
FAIL_PARAMETERS, and return -EINVAL.

 is crashed

pm80xx_get_non_fatal_dump() can be called even after the controller has
entered a fatal error state. In that case the forensic memory contents
are not safe to access for a non-fatal dump request, and attempting to
do so can trigger a call trace.

Check controller_fatal_error before reading the non-fatal dump buffer
and return -EINVAL when the controller is already in a crashed state.

This prevents non-fatal dump collection from running in an invalid
controller state.

Subject: [PATCH 0989/5214] scsi: ufs: core: Configure only active lanes during
 link

The number of connected lanes detected during UFS link startup can be
fewer than the lanes specified in the device tree. The current driver
logic attempts to configure all lanes defined in the device tree,
regardless of their actual availability. This mismatch may cause
failures during power mode changes.

Hence, Add a check during link startup to ensure that only the lanes
actually discovered are considered valid. If a mismatch is detected,
fail the initialization early, preventing the driver from entering an
unsupported configuration that could cause power mode transition
failures.

Subject: [PATCH 0990/5214] scsi: ufs: ufs-qcom: Enable Auto Hibern8 clock
 request support

On platforms that support Auto Hibern8 (AH8), the UFS controller can
autonomously de-assert clk_req signals to the Global Clock Controller
when entering the Hibern8 state. This allows Global Clock Controller
(GCC) to gate unused clocks, improving power efficiency.

Enable the Clock Request feature by setting the UFS_HW_CLK_CTRL_EN bit
in the UFS_AH8_CFG register, as recommended in the Hardware Programming
Guidelines.

Use guard() for handling mutex lock instead of locking and unlocking
mutex explicitly. This improves readability by eliminating the need for
gotos and by clearly indicating mutex will be locked only when
execution is in guard scope.

seemlingly endless stream of identical messages on the console:

Subject: [PATCH 0997/5214] perf unwind: Refactor get_entries to allow dynamic
 libdw/libunwind selection

Currently, both libdw and libunwind define 'unwind__get_entries'. This
causes a duplicate symbol build failure when both are compiled into
perf.

This commit refactors the DWARF unwind post-processing to be
configurable at runtime via the .perfconfig file option
'unwind.style', or using the argument '--unwind-style' in the commands
'perf report', 'perf script' and 'perf inject', in a similar manner to
the addr2line or the disassembler style.

The file 'tools/perf/util/unwind.c' adds the top-level dispatch
function 'unwind__get_entries'. The backend implementations are
renamed to 'libdw__get_entries' and 'libunwind__get_entries'. Both are
attempted as fallbacks if not configured, or if the primary backend
fails.

Fixes: 2e9191573a69ff96 ("perf build: Remove NO_LIBDW_DWARF_UNWIND option")

Subject: [PATCH 0998/5214] tools build: Deduplicate test-libunwind for
 different architectures

The separate test files only exist to pass a different #include,
instead have a single source file and pass -include to $(CC) to
include the relevant header file for the architecture being
tested. Generate the rules using a foreach loop. Include tests for all
current libunwind architectures.

Subject: [PATCH 0999/5214] perf build: Be more programmatic when setting up
 libunwind variables

Iterate LIBUNWIND_ARCHS when setting up CONFIG_ and HAVE_ definitions
rather than treating each architecture individually. This sets up the
libunwind build variables and C definitions beyond x86 and
arm/aarch64. The existing naming convention is followed for
compatibility.

Subject: [PATCH 1000/5214] media: i2c: lm3560: Fix v4l2 subdev registration

The existing driver does not call media subdev registration, making it
invisible to the media framework. Since the LM3560 supports two
independent LEDs, register each LED as a separate media entity.

Because registering LEDs before device initialization may cause access
attempts before the hardware is ready, lm3560_init_device has been moved
before the subdevice initializations.

An additional helper, lm3560_subdev_cleanup, was added to release LED0 if
the initialization of LED1 fails, and to deregister both LEDs in the
remove function.

Subject: [PATCH 1001/5214] media: i2c: lm3560: Optimize mutex lock usage

Pass the device's own mutex lock to the control handler so that the media
framework can handle control access instead of managing it manually. The
lock must be common to both sub-devices since they share same hardware,
so the individual sub-device locks will not work here.

Subject: [PATCH 1002/5214] media: i2c: lm3560: Convert to use OF bindings

Since there are no users of this driver via platform data, remove the
platform data support and switch to using Device Tree bindings.

Converting to Device Tree assumes dynamic and independent registration of
LEDs. To monitor the configured LEDs, a bitmap has been added. This makes
LED cleanup more robust and less context dependent.

Subject: [PATCH 1003/5214] media: i2c: lm3560: Add support for PM features

Add support for power management features to better control the LM3560
within the media framework. To achieve the desired PM support, the HWEN
GPIO and VIN power supply were added and configured into power on/off
sequences. Added PM operations along with the PM configuration setup.

Subject: [PATCH 1004/5214] media: i2c: lm3560: Add proper support for LM3559

The LM3559 is very similar to the LM3560, but it operates at much lower
currents. This may result in incorrect current selection if LM3560 ranges
are applied to the LM3559. Implement driver data matching to use
device-specific current configurations.

Since the driver no longer supports platform data and device configuration
is performed more granularly, move the remaining enums from the header
into the driver file and remove the header.

The ad4062 driver gained support for the gpiochip and now fails
to build when GPIOLIB is disabled:

390-linux-ld: drivers/iio/adc/ad4062.o: in function `ad4062_gpio_get':
drivers/iio/adc/ad4062.c:1383:(.text+0x3dc): undefined reference to `gpiochip_get_data`

Add a Kconfig dependency for this.

Subject: [PATCH 1006/5214] iio: light: veml6075: add bounds check to
 veml6075_it_ms index

veml6075_it_ms has 5 elements but VEML6075_CONF_IT can yield values 0-7.
If it returns a value >= 5, this causes an out-of-bounds array access.
Add a bounds check and return -EINVAL if the index is out of range.

The problem values are reserved so should never be read from the
register. Hence this is hardening against fault device, missprogramming
or bus corruption.

Remove the redundant mode field from struct dra7xx_pcie and use the
existing mode field in struct dw_pcie instead.

This avoids duplication and prevents potential inconsistencies between

Subject: [PATCH 1012/5214] PCI: altera: Do not dispose parent IRQ mapping

altera_pcie_irq_teardown() calls irq_dispose_mapping() on pcie->irq.
However, pcie->irq is the parent IRQ returned by platform_get_irq(), not
the mapping created by Altera INTx irq_domain.

The Altera driver only sets the chained handler on the parent IRQ. It
should detach that handler during teardown, but it should not dispose the
parent IRQ mapping, which belongs to the parent interrupt controller's
irq_domain.

Drop irq_dispose_mapping(pcie->irq) from the teardown path.

Note that during irqchip remove(), the child IRQs should've disposed. But
since the chained handler itself is removed, there is no way the stale
child IRQs (if exists) could fire. So it is safe here.

Subject: [PATCH 1013/5214] PCI: altera: Fix resource leaks on probe failure

The chained IRQ handler is set during probe, but is only removed during the
driver remove(). If pci_host_probe() fails, the handler and INTx IRQ
domain remain set even though the devm-managed host bridge storage
containing struct altera_pcie will be released, leaving the handler with
a stale data pointer.

Interrupts are also enabled before pci_host_probe() is called. If probe
fails after that point, the controller interrupt source should be disabled
before the chained handler and INTx domain are removed.

So set the chained handler only after the INTx domain has been created.
Disable controller interrupts during IRQ teardown, and tear the IRQ setup
down if pci_host_probe() fails.

Subject: [PATCH 1014/5214] perf unwind-libunwind: Make libunwind register
 reading cross platform

Move the libunwind register to perf register mapping functions in
arch/../util/unwind-libunwind.c into a new libunwind-arch
directory. Rename the functions to
__get_perf_regnum_for_unw_regnum_<arch>. Add untested ppc32 and s390
functions. Add a get_perf_regnum_for_unw_regnum function that takes an
ELF machine as well as a register number and chooses the appropriate
architecture implementation.

Split the x86 and powerpc 32 and 64-bit implementations apart so that
a single libunwind-<arch>.h header is included.

Move the e_machine into the unwind_info struct to make it easier to
pass.

Subject: [PATCH 1015/5214] perf unwind-libunwind: Move flush/finish access out
 of local

Flush and finish access are relatively simple calls into libunwind,
move them out struct unwind_libunwind_ops. So that the correct version
can be called, add an e_machine variable to maps. This size regression
will go away when the unwind_libunwind_ops no longer need stashing in
the maps. To set the e_machine up pass it into unwind__prepare_access,
which no longer needs to determine the unwind operations based on a
map dso because of this. This also means the maps copying code can
call unwind__prepare_access once for the e_machine rather than once
per map.

Subject: [PATCH 1016/5214] perf unwind-libunwind: Remove libunwind-local

Local unwinding only works on the machine libunwind is built for,
rather than cross platform, the APIs for remote and local unwinding
are similar but types like unw_word_t depend on the included
header. Place the architecture specific code into the appropriate
libunwind-<arch>.c file. Put generic code in unwind-libunwind.c and
use libunwind-arch to choose the correct implementation based on the
thread's e_machine. Structuring the code this way avoids including the
unwind-libunwind-local.c for each architecture of remote
unwinding. Data is moved into the struct unwind_info to simplify the
architecture and generic code, trying to keep as much code as possible
generic.

Subject: [PATCH 1018/5214] perf trace beauty fcntl: Fix build with older
 kernel headers

Toolchains with older kernel headers that do not include upstream commit
c75b1d9421f80f41 ("fs: add fcntl() interface for setting/getting write
life time hints") will now fail to build perf due to missing definitions
for F_GET_RW_HINT/F_SET_RW_HINT/F_GET_FILE_RW_HINT/F_SET_FILE_RW_HINT.

Provide a fallback definition for these when they are not already
defined.

Subject: [PATCH 1019/5214] perf pmu: Skip test on Arm64 when #slots is zero

Some Arm64 PMUs expose 'caps/slots' as 0 when the slot count is not
implemented, tool_pmu__read_event() currently returns false for this,
so metrics that reference #slots are reported as syntax error.

Since the commit 3a61fd866ef9 ("perf expr: Return -EINVAL for syntax
error in expr__find_ids()"), these syntax errors are populated as
failures and make the PMU metric test fail:

    9.3: Parsing of PMU event table metrics:
    --- start ---
    ...

    Found metric 'backend_bound'
    metric expr 100 * (stall_slot_backend / (#slots * cpu_cycles)) for backend_bound
    parsing metric: 100 * (stall_slot_backend / (#slots * cpu_cycles))
    Failure to read '#slots'
    literal: #slots = nan
    syntax error
    Fail to parse metric or group `backend_bound'

    ...
    ---- end(-1) ----
    9.3: Parsing of PMU event table metrics    : FAILED!

This commit introduces a new function is_expected_broken_metric() to
identify broken metrics, and treats metrics containing "#slots" as
expected broken when #slots == 0 on Arm64 platforms.

Subject: [PATCH 1020/5214] iio: pressure: bmp280: zero-init bmp580 trigger
 handler buffer

bmp580_trigger_handler() builds an on-stack scan buffer containing
two __le32 fields and an aligned_s64 timestamp, and pushes it to
userspace via iio_push_to_buffers_with_ts(). However, only the low
3 bytes of each __le32 field are populated by the device data:

	memcpy(&buffer.comp_press, &data->buf[3], 3);
	memcpy(&buffer.comp_temp,  &data->buf[0], 3);

The high byte of each field is left uninitialised on the stack.
The bmp580 channels declare storagebits = 32, so the IIO core
transports all four bytes per sample to userspace as part of the
scan element, leaking two bytes of kernel stack per scan.

Zero-initialise the buffer before populating it, mirroring the fix
applied to bme280_trigger_handler() in commit 018f50909e66 ("iio:
bmp280: zero-init buffer").

Subject: [PATCH 1021/5214] iio: gyro: bmg160: bail out when bandwidth/filter
 is not in table

bmg160_get_filter() walks bmg160_samp_freq_table[] looking for the entry
matching the bw_bits value read from the chip:

	for (i = 0; i < ARRAY_SIZE(bmg160_samp_freq_table); ++i) {
		if (bmg160_samp_freq_table[i].bw_bits == bw_bits)
			break;
	}
	*val = bmg160_samp_freq_table[i].filter;

If no entry matches, i ends up equal to the array size and the next line
reads one slot past the end. bmg160_set_filter() has the same shape, driven
by 'val' instead of bw_bits.

smatch flags both:

  drivers/iio/gyro/bmg160_core.c:204 bmg160_get_filter() error:
  buffer overflow 'bmg160_samp_freq_table' 7 <= 7
  drivers/iio/gyro/bmg160_core.c:222 bmg160_set_filter() error:
  buffer overflow 'bmg160_samp_freq_table' 7 <= 7

Return -EINVAL when no entry matches.

The set_filter() path is reachable from userspace via the sysfs
in_anglvel_filter_low_pass_3db_frequency interface, so userspace can
trivially trigger the out-of-bounds read with a value that is not in
bmg160_samp_freq_table[].filter.

Subject: [PATCH 1022/5214] iio: gyro: bmg160: wait full startup time after
 mode change at probe

bmg160_chip_init() calls bmg160_set_mode(BMG160_MODE_NORMAL) and
then waits only 500-1000 us. Per the BMG160 datasheet
(BST-BMG160-DS000-07 Rev. 1.0, May 2013), the start-up and wake-up
times (tsu, twusm) are 30 ms.

The same file already waits BMG160_MAX_STARTUP_TIME_MS (80 ms)
in bmg160_runtime_resume() after the same set_mode(NORMAL)
operation. The 500 us value at probe was likely a unit mix-up;
the old comment said "500 ms" while the code used microseconds.

Reuse the same constant via msleep() and add a code comment
explaining the datasheet basis for the wait. Without this,
register writes that follow the mode change can hit the chip
before it is ready.

Subject: [PATCH 1023/5214] iio: proximity: vl53l0x: notify trigger and clear
 IRQ on error paths

vl53l0x_trigger_handler() returns directly on the I2C read failure
paths without calling iio_trigger_notify_done() or vl53l0x_clear_irq().

A single transient i2c_smbus_read_i2c_block_data() failure (negative
errno or a short read) therefore leaves two pieces of state behind:

  - iio_trigger_notify_done() never decrements the trigger's use_count,
    so iio_trigger_poll_nested() silently drops further dispatches
    (see industrialio-trigger.c, the !atomic_read(&trig->use_count)
    guard);
  - vl53l0x_clear_irq() never writes SYSTEM_INTERRUPT_CLEAR, so the
    chip keeps the DRDY interrupt asserted.

The sensor's buffer mode stays wedged from then on, recoverable only
by re-binding the driver. The sibling driver vl53l1x-i2c.c handles
exactly the same case correctly by jumping to a "notify_and_clear_irq"
label that always calls both helpers; mirror that here.

The bogus negative-int return value cast to irqreturn_t also goes
away as a side effect.

Subject: [PATCH 1027/5214] perf trace: Introduce --show-cpu option to display
 cpu id

When tracing system-wide workloads or specific events, it is highly
valuable to know exactly which CPU executed a specific event. Currently,
perf trace output defaults to omitting CPU information.

Introduce a new "--show-cpu" command-line option. When provided, this
flag extracts the CPU from the perf sample and prints it in a "[000]"
format immediately following the timestamp. This mirrors the behaviour of
other tracing tools like ftrace and perf script. For example:

  # perf trace -e sched:sched_switch --max-events 5 --show-cpu
       0.000 [002] :0/0 sched:sched_switch(prev_comm: "swapper/2", prev_prio: 120, next_comm: "rcu_preempt", next_pid: 16 (rcu_preempt), next_prio: 120)
       0.009 [002] rcu_preempt/16 sched:sched_switch(prev_comm: "rcu_preempt", prev_pid: 16 (rcu_preempt), prev_prio: 120, prev_state: 128, next_comm: "swapper/2", next_prio: 120)
       0.033 [002] :0/0 sched:sched_switch(prev_comm: "swapper/2", prev_prio: 120, next_comm: "kworker/u32:48", next_pid: 35840 (kworker/u32:48-), next_prio: 120)
       0.041 [002] kworker/u32:48/35840 sched:sched_switch(prev_comm: "kworker/u32:48", prev_pid: 35840 (kworker/u32:48-), prev_prio: 120, prev_state: 128, next_comm: "swapper/2", next_prio: 120)
       0.045 [002] :0/0 sched:sched_switch(prev_comm: "swapper/2", prev_prio: 120, next_comm: "kworker/u32:48", next_pid: 35840 (kworker/u32:48-), next_prio: 120)

The feature is implemented strictly as an opt-in toggle to prevent
cluttering the standard output and to preserve backwards compatibility
for scripts parsing the default output format.

Subject: [PATCH 1028/5214] iio: resolver: ad2s1210: notify trigger and clear
 state on fault read error

ad2s1210_trigger_handler() walks several scan-mask branches and uses
"goto error_ret" to land on the iio_trigger_notify_done() teardown at
the bottom of the function for every I/O error -- except the
MOD_CONFIG fault-register read, which uses a bare "return ret":

	if (st->fixed_mode == MOD_CONFIG) {
		unsigned int reg_val;

		ret = regmap_read(st->regmap, AD2S1210_REG_FAULT, &reg_val);
		if (ret < 0)
			return ret;
		...
	}

Two problems on that path:

  - the handler returns a negative errno where the prototype expects
    an irqreturn_t (IRQ_HANDLED / IRQ_NONE), so the caller in the
    IIO core sees a value outside the enum;
  - iio_trigger_notify_done() is skipped, leaving the trigger
    busy-flag set. A single transient SPI/regmap error on the fault
    read then wedges the trigger so subsequent samples are dropped
    until the consumer is detached.

Convert the error path to "goto error_ret" so the failure path goes
through the same notify_done() teardown as every other error in the
handler.

Every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device's ACPI companion
object need to verify its presence.

Accordingly, add a requisite ACPI_COMPANION() check against NULL to the
acpi-als IIO driver.

Subject: [PATCH 1031/5214] clk: qcom: clk-rpmh: Make all VRMs optional

Some VRMs aren't present on all boards, so mark them as optional. This
prevents probe failures on boards where not all VRMs are present.

This resolves an issue seen on the Nothing Phone (4a) Pro (Eliza) where
probe fails due to RPMH_RF_CLK5 not being present on the board, this is
due to this device having a slightly different PMIC configuration from
the Eliza MTP.

This matches the downstream approach of marking all VRMs as optional
and makes the previous clka_optional handling redundant.

Subject: [PATCH 1035/5214] coresight: Fix source not disabled on idr_alloc_u32
 failure

In coresight_enable_sysfs(), for non-CPU sources (SOFTWARE, TPDM,
OTHERS), the source device is enabled via coresight_enable_source_sysfs()
before idr_alloc_u32() maps the path. If idr_alloc_u32() fails, the
original code jumped directly to err_source, which only calls
coresight_disable_path() and coresight_release_path(). The source device
was left enabled with an incremented refcnt but no path tracked for it,
leaving the device in an inconsistent state.

Disable the source before jumping to err_source so the enable and path
operations are fully unwound.

Subject: [PATCH 1039/5214] coresight: Remove .cpu_id() callback from source
 ops

The CPU ID can be fetched directly from the coresight_device structure,
so the .cpu_id() callback is no longer needed.

Remove the .cpu_id() callback from source ops and update callers
accordingly.

Subject: [PATCH 1040/5214] coresight: Take hotplug lock in
 enable_source_store() for Sysfs mode

The hotplug lock is acquired and released in etm{3|4}_disable_sysfs(),
which are low-level functions.  This prevents us from a new solution for
hotplug.

Firstly, hotplug callbacks cannot invoke etm{3|4}_disable_sysfs() to
disable the source; otherwise, a deadlock issue occurs.  The reason is
that, in the hotplug flow, the kernel acquires the hotplug lock before
calling callbacks.  Subsequently, if coresight_disable_source() is
invoked and it calls etm{3|4}_disable_sysfs(), the hotplug lock will be
acquired twice, leading to a double lock issue.

Secondly, when hotplugging a CPU on or off, if we want to manipulate all
components on a path attached to the CPU, we need to maintain atomicity
for the entire path.  Otherwise, a race condition may occur with users
setting the same path via the Sysfs knobs, ultimately causing mess
states in CoreSight components.

This patch moves the hotplug locking from etm{3|4}_disable_sysfs() into
enable_source_store().  As a result, when users control the Sysfs knobs,
the whole flow is protected by hotplug locking, ensuring it is mutual
exclusive with hotplug callbacks.

Note, the paired function etm{3|4}_enable_sysfs() does not use hotplug
locking, which is why this patch does not modify it.

Subject: [PATCH 1041/5214] coresight: perf: Retrieve path and source from
 event data

ETM perf callbacks currently use the per-CPU csdev_src pointer, which
can race with updates during device registration and unregistration.

The AUX setup already builds and stores the path in the event data.
Use this path to retrieve the source instead of csdev_src to avoid
the race.

Export coresight_get_source() and add etm_event_get_ctxt_path() to
retrieve the context's path and its source with READ_ONCE() /
WRITE_ONCE() accessors. Give the comments to explain why this
approach is safe when pause or resume callbacks preempt the disable
callback (e.g. via NMI).

Subject: [PATCH 1042/5214] coresight: Take a reference on csdev

coresight_get_ref() currently pins the provider module and takes a
reference on the parent device, but it does not pin &csdev->dev. Take a
reference on &csdev->dev when grabbing a CoreSight device and drop it in
coresight_put_ref().

Reorder the sequence to follow child-to-parent dependencies: first take
a reference on csdev, then on the parent device and grab the driver
module. Once the data and module are pinned, take a PM runtime
reference to power on the hardware.

Subject: [PATCH 1043/5214] coresight: Move per-CPU source pointer to core
 layer

Move the per-CPU source pointer from ETM perf to the core layer, as this
will be used for not only perf session and also for CPU PM notifiers.

Provides coresight_{set|clear|get}_percpu_source() helpers to access the
per-CPU source pointer. Add a raw spinlock to protect exclusive access.

Device registration and unregistration call the set and clear helpers
for init and teardown the pointers.

Update callers to invoke coresight_get_percpu_source() for retrieving
the pointer.

Subject: [PATCH 1044/5214] coresight: Take per-CPU source reference during AUX
 setup

etm_setup_aux() fetches the per-CPU source pointer while preparing perf
AUX trace paths. This can race with CoreSight device unregistration, the
ETM device may has been released while the AUX setup still use it,
leading to use-after-free.

Move per-CPU path construction into etm_event_build_path() and use
the coresight_{get|put}_percpu_source_ref() pairs to take and drop
the device references, this ensures the device is safe to access during
path construction.

Update comments accordingly. Document a PREEMPT_RT corner case: the
put_device() may release resources while coresight_dev_lock (a raw
spinlock) is held, and the release may attempt to acquire a spinlock
that becomes sleepable under PREEMPT_RT. This will be fixed in the
future.

Subject: [PATCH 1045/5214] coresight: Register CPU PM notifier in core layer

The current implementation only saves and restores the context for ETM
sources while ignoring the context of links.  However, if funnels or
replicators on a linked path resides in a CPU or cluster power domain,
the hardware context for the link will be lost after resuming from low
power states.

To support context management for links during CPU low power modes, a
better way is to implement CPU PM callbacks in the Arm CoreSight core
layer.  As the core layer has sufficient information for linked paths,
from tracers to links, which can be used for power management.

As a first step, this patch registers CPU PM notifier in the core layer.
If a source device provides callbacks for saving and restoring context,
these callbacks will be invoked in CPU suspend and resume.

Subject: [PATCH 1046/5214] coresight: etm4x: Hook CPU PM callbacks

Add a helper etm4_pm_save_needed() to detect if need save context for
self-hosted PM mode and hook pm_save_disable() and pm_restore_enable()
callbacks through etm4_cs_pm_ops structure.  With this, ETMv4 PM
save/restore is integrated into the core layer's CPU PM.

Organize etm4_cs_ops and etm4_cs_pm_ops together for more readable.

The CPU PM notifier in the ETMv4 driver is no longer needed, remove it
along with its registration and unregistration code.

ETMv4 driver save/restore callbacks still re-check conditions that are
already validated by the core layer before the callbacks are invoked.

Remove the duplicated checks and fold the two-level functions into
direct callback implementations.  The obsolete WARN_ON() checks are
removed as well.

cscfg_config_sysfs_get_active_cfg() will be used from idle flows, while
sleeping locks are not allowed.  Introduce sysfs_store_lock to replace
the mutex to protect sysfs_active_config and sysfs_active_preset
accesses, with IRQ-safe locking to avoid lockdep complaint.

Refactor cscfg_config_sysfs_activate() to use spinlock for
sysfs_active_config and activate/deactivate config.

Subject: [PATCH 1049/5214] coresight: Disable source helpers in
 coresight_disable_path()

coresight_enable_path() enables helpers attached to every device in
the path, including those bound to the source. However,
coresight_disable_path() skips the source node, so source helpers had
to be disabled separately in coresight_disable_source().

Move source helper disabling into coresight_disable_path() instead.
Make coresight_disable_path_from() start from the passed node nd, so
it can also disable helpers on the source. Update the comments
accordingly.

As coresight_disable_path_from() now changes its semantics from
"start beyond nd" to "start from nd", update the failure handling in
coresight_enable_path(). If enabling a node fails, iterate to the
previous node (the last successfully enabled one) and pass it to
coresight_disable_path_from() for rollback.

Subject: [PATCH 1050/5214] coresight: Control path with range

CPU PM notifiers need to control only part of a path instead of always
operating on the full path.

Add internal enable and disable helpers that take an inclusive node
range [from, to], validate that the requested nodes are ordered before
using them.

Update the existed coresight_{enable|disable}_path() interfaces as
full-path wrappers by passing the first and last path nodes. The helpers
coresight_path_{first|last}_node() are provided for conveniently
fetching the first and last nodes on the path.

In coresight_enable_path_from_to(), if a failure occurs at the last node
in the range, no device is actually enabled in this case, bail out
directly.

Subject: [PATCH 1053/5214] coresight: Save active path for system tracers

This commit only set the path pointer for system tracers (e.g. STM) in
coresight_{enable|disable}_source().

Later changes will set the path pointer locally for per-CPU sources.
This is because the mode and path pointer must be set together, so that
they are observed atomically by the CPU PM notifier.

As a result, the global variables used for caching path pointers are no
longer needed. Remove them to simplify the code.

Subject: [PATCH 1057/5214] coresight: Control path during CPU idle

Extend the CPU PM flow to control the path: disable from source up to
the node before the sink, then re-enable the same range on restore.
To avoid latency, control it up to the node before the sink.

Track per-CPU PM restore failures using percpu_pm_failed.  Once a CPU
hits a restore failure, set the percpu_pm_failed and return NOTIFY_BAD
on subsequent notifications to avoid repeating half-completed
transitions.

Setting percpu_pm_failed permanently blocks CPU PM on that CPU.  Such
failures are typically seen during development; disabling PM operations
simplifies the implementation, and a warning highlights the issue.
Clear this flag when the source device is unregistered.

Subject: [PATCH 1058/5214] coresight: Add PM callbacks for sink device

Unlike system level sinks, per-CPU sinks may lose power during CPU idle
states.  Currently, this applies specifically to TRBE.  This commit
invokes save and restore callbacks for the sink in the CPU PM notifier.

If the sink provides PM callbacks but the source does not, this is
unsafe because the sink cannot be disabled safely unless the source
can also be controlled, so veto low power entry to avoid lockups.

Subject: [PATCH 1059/5214] coresight: trbe: Save and restore state across CPU
 low power state

TRBE context can be lost when a CPU enters low power states.  If a trace
source is restored while TRBE is not, tracing may run without an active
sink, which can lead to hangs on some devices (e.g., Pixel 9).

The save and restore flows are described in the section K5.5 "Context
switching" of Arm ARM (ARM DDI 0487 L.a). This commit adds save and
restore callbacks with following the software usages defined in the
architecture manual.

During the restore flow, since TRBLIMITR_EL1.E resets to 0 on a warm
reset, the trace buffer unit is disabled when idle resume, it is safe to
restore base/pointer/status registers first and program TRBLIMITR_EL1
last.

Subject: [PATCH 1060/5214] coresight: sysfs: Increment refcount only for
 software source

Except for software sources (e.g. STM), other sources treat multiple
enables as equivalent to a single enable. The device mode already
tracks the binary state, so it is redundant to operate refcount.

Introduce a helper coresight_is_software_source() for check software
source. Refactor to maintain the refcount only for software sources.
This simplifies future CPU PM handling without refcount logic.

Subject: [PATCH 1061/5214] coresight: Move CPU hotplug callbacks to core layer

This commit moves CPU hotplug callbacks from ETMv4 driver to core layer.
The motivation is the core layer can control all components on an
activated path rather but not only managing tracer in ETMv4 driver.

The perf event layer will disable CoreSight PMU event 'cs_etm' when
hotplug off a CPU.  That means a perf mode will be always converted to
disabled mode in CPU hotplug.  Arm CoreSight CPU hotplug callbacks only
need to handle the Sysfs mode and ignore the perf mode.

Add a 'mode' argument to coresight_pm_get_active_path() so it only
returns active paths for the relevant mode. Define the enum with bit
flags so it is safe for bitwise operations.

Change CPUHP_AP_ARM_CORESIGHT_STARTING to CPUHP_AP_ARM_CORESIGHT_ONLINE
so that the CPU hotplug callback runs in the online state and thread
context, allowing coresight_disable_sysfs() to be called directly to
disable the path.

Subject: [PATCH 1062/5214] coresight: sysfs: Validate CPU online status for
 per-CPU sources

The current SysFS flow first enables the links and sink, then rolls back
to disable them if the source fails to enable. This failure can occur if
the associated CPU is offline, which causes the SMP call to fail.

Validate whether the associated CPU is online for a per-CPU tracer.
If the CPU is offline, return -ENODEV and bail out.

Subject: [PATCH 1065/5214] PCI: mediatek-gen3: Fix PERST# control timing
 during system startup

Some MediaTek chips stop generating REFCLK if the PCIE_PHY_RSTB signal of
PCIe controller is asserted at the start of mtk_pcie_devices_power_up().

But the driver deasserts PCIE_PHY_RSTB together with PCIE_PE_RSTB signal
that is used to deassert PERST#. This violates PCIe CEM r6.0, sec 2.11.2,
which mandates waiting for 100ms (PCIE_T_PVPERL_MS) after power becomes
stable.

Move the MAC, PHY and BRG reset deassert code above the PCIE_T_PVPERL_MS
delay and leave the PCIE_PE_RSTB deassertion after the delay.

Add the 10ms delay mentioned in the MediaTek datasheet after asserting
PCIE_BRG_RSTB and before accessing the PCIE_RST_CTRL_REG register.

Subject: [PATCH 1067/5214] PCI: mediatek-gen3: Do full device power down on
 removal

When power control for downstream devices was introduced in the
mediatek-gen3 PCIe controller driver, only the power to the downstream
devices was cut when the controller driver is removed. This matched
existing behavior, but in hindsight a proper power down sequence should
have been followed.

Call mtk_pcie_devices_power_down() on driver removal so that in addition
to removing power from the downstream devices, PERST# is asserted.

Subject: [PATCH 1068/5214] mailbox: mpfs: fix check for syscon presence in
 mpfs_mbox_inbox_isr()

mpfs_mbox_inbox_isr() writes to the sysreg scb syscon, not the control
scb syscon, but checks for the presence of the latter. Ultimately this
makes little difference because if one syscon is present, both will be.

Subject: [PATCH 1070/5214] mailbox: qcom-cpucp: Add support for Nord CPUCP
 mailbox controller

The Nord SoC CPUCP mailbox supports 16 IPC channels, compared to 3 on
x1e80100. The existing driver hardcodes the channel count via a
compile-time constant (APSS_CPUCP_IPC_CHAN_SUPPORTED), making it
impossible to support hardware with a different number of channels.

Introduce a qcom_cpucp_mbox_data per-hardware configuration struct that
carries the channel count, and retrieve it via of_device_get_match_data()
at probe time. Switch the channel array from a fixed-size member to a
dynamically allocated buffer sized from the hardware data. Update the
x1e80100 entry to supply its own data struct, and add a new Nord entry
with num_chans = 16.

Subject: [PATCH 1076/5214] mailbox: mtk-adsp: fix UAF during device teardown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the SOF audio driver fails to initialize (e.g. firmware boot
timeout), its devres unwind frees the snd_sof_dev object that the
mailbox client (mtk-adsp-ipc) reaches via chan->cl->rx_callback.
The mtk-adsp-mailbox shutdown clears the mailbox command registers
but leaves the IRQ line unmasked, so a late interrupt can still
queue a threaded handler after mbox_free_channel() had cleared
chan->cl, and mbox_chan_received_data() would then trigger UAF:

  BUG: KASAN: slab-use-after-free in sof_ipc3_validate_fw_version
   sof_ipc3_validate_fw_version
   sof_ipc3_do_rx_work
   sof_ipc3_rx_msg

   irq_thread_fn
  Freed by task ...:
   kfree
   devres_release_all
   really_probe
   ... (sof-audio-of-mt8196 probe failure)

The crash was observed roughly three seconds after the failed probe.

disable_irq() in shutdown and enable_irq() in startup. disable_irq()
also waits for any in-flight interrupts, so by the time
mbox_free_channel() proceeds to clear chan->cl no rx_callback can run.

In addition, request the IRQ with IRQF_NO_AUTOEN so it stays masked
between probe and the first client bind — otherwise an early interrupt
can crash on chan->cl == NULL in mbox_chan_received_data().

Unlike in non-blocking mode, multi-thread has not been supported in
blocking mode. This commit is to prevent clients from having wrong
assumption by explicitly specifying this fact to the API doc.

Subject: [PATCH 1078/5214] mailbox: Make mbox_send_message() return error code
 when tx fails

When the mailbox controller failed transmitting message, the error code
was only passed to the client's tx done handler and not to
mbox_send_message() in blocking mode. For this reason, the function could
return a false success. This commit resolves the issue by introducing the
tx status and checking it before mbox_send_message() returns.

This commit works with the premise that the multi-threads' access to a
channel in blocking mode is serialized by clients, not by the mailbox
APIs, since the current mbox_send_message() in blocking mode does not
support multi-threads.

Subject: [PATCH 1079/5214] mailbox: don't free the channel if the startup
 callback failed

If the optional startup() callbacks fails, we need to clear some states.
Currently, this is done by freeing the channel. This does, however, more
than needed which creates problems. Namely, it is calling the shutdown()
callback. This is totally not intuitive. No user expects that shutdown()
is called when startup() fails, similar to remove() not being called
when probe() fails. Currently, quite some mailbox users register the IRQ
in startup() and free them in shutdown(). These drivers will get a WARN
about freeing an already free IRQ. Other subtle issues could arise from
this unexpected behaviour.

To solve this problem, introduce a helper which does the minimal cleanup
and use it in both, in free_channel() and after startup() failed.

Subject: [PATCH 1081/5214] PCI: Log device readiness timeouts as errors

pci_dev_wait() waits for a device to be Configuration-Ready after a reset,
such as a Function-Level Reset (FLR), a soft reset during a D3hot->
D0uninitialized transition when No_Soft_Reset == 0), or a power-up sequence
from D3cold->D0uninitialized.

If pci_dev_wait() returns success, the device is guaranteed to respond to
configuration requests with Successful Completion status.  If it times out,
device is completely non-responsive.

Upgrade the log level from pci_warn() to pci_err() to reflect this failure
state.

Subject: [PATCH 1082/5214] PCI: Wait for device readiness after D3hot ->
 D0uninitialized transition

For a device that advertises No_Soft_Reset == 0, a transition from D3hot to
D0uninitialized is a soft reset, and the resulting internal device state is
undefined.

Per PCIe r7.0, sec 2.3.1, a transition from D3hot to D0uninitialized
mandates a minimum 10 ms delay before accessing the device. Following this
delay, the device is permitted to respond to initial configuration requests
with a Request Retry Status (RRS) completion status if it needs more time
to initialize.

Call pci_dev_wait() after pci_power_up() performs a D3hot->D0uninitialized
transition to ensure the device is ready to accept config accesses, as is
done after the similar transition in pci_pm_reset().

If the device is already ready, this is essentially a no-op except for one
additional config read.

Subject: [PATCH 1083/5214] PCI: Drop unnecessary retries when restoring BARs

In 2012, commit 26f41062f28d ("PCI: check for pci bar restore completion
and retry") amended pci_restore_state() to attempt BAR restoration up to 10
times.  This was necessary because back in the day, only a 100 msec delay
was observed after pcie_flr() carried out a Function Level Reset.  The
retries ensured that BARs were restored even if devices needed more time to
come out of reset.

In 2016, commit 5adecf817dd6 ("PCI: Wait for up to 1000ms after FLR reset")
extended the delay to 1 sec.  Commit a2758b6b8fdb ("PCI: Rename
pci_flr_wait() to pci_dev_wait() and make it generic") subsequently
extended it further to 60 sec.

The lengthened delay makes it unnecessary to retry BAR restoration, so
drop it.

Subject: [PATCH 1085/5214] PCI: imx6: Fix IMX6SX_GPR12_PCIE_TEST_POWERDOWN
 handling

The IMX6SX_GPR12_PCIE_TEST_POWERDOWN bit does not control the PCIe
reference clock on i.MX6SX. Instead, it is part of i.MX6SX PCIe core
reset sequence.

Move the IMX6SX_GPR12_PCIE_TEST_POWERDOWN assertion/deassertion into
the core reset functions to properly reflect its purpose. Remove the
.enable_ref_clk() callback for i.MX6SX since it was incorrectly
manipulating this bit.

 Root Port node

Update fsl,imx6q-pcie.yaml to include the standard reset-gpios property for
the Root Port node.

The reset-gpios property is already defined in pci-bus-common.yaml for
PERST#, so use it instead of the local reset-gpio property. Keep the
existing reset-gpio property in the bridge node for backward compatibility,
but mark it as deprecated.

Subject: [PATCH 1087/5214] PCI: host-generic: Add common helpers for parsing
 Root Port properties

Introduce generic helper functions to parse Root Port device tree nodes and
extract common properties like reset GPIOs. This allows multiple PCI host
controller drivers to share the same parsing logic.

Define struct pci_host_port to hold common Root Port properties (currently
only list of PERST# GPIO descriptors) and add pci_host_common_parse_ports()
to parse Root Port nodes from device tree.

Also add the 'ports' list to struct pci_host_bridge to better maintain
parsed Root Port information.

Subject: [PATCH 1088/5214] PCI: imx6: Assert PERST# before enabling regulators

The PCIe endpoint may start responding or driving signals as soon as its
supply is enabled, even before the reference clock is stable.  Asserting
PERST# before enabling the regulator ensures that the endpoint remains in
reset throughout the entire power-up sequence, until both power and refclk
are known to be stable and link initialization can safely begin.

Currently, the driver enables the vpcie3v3aux regulator in imx_pcie_probe()
before PERST# is asserted in imx_pcie_host_init(), which may cause PCIe
endpoint undefined behavior during early power-up. However, there is no
issue so far because PERST# is requested as GPIOD_OUT_HIGH in
imx_pcie_probe(), which guarantees that PERST# is asserted before enabling
the vpcie3v3aux regulator.

This prepares for an upcoming changes that will parse the reset property
using the new Root Port binding, which will use GPIOD_ASIS when requesting
the reset GPIO. With GPIOD_ASIS, the GPIO state is not guaranteed, so
explicit sequencing is required.

Fix the power sequencing by:

  1. Moving vpcie3v3aux regulator enable from probe to
     imx_pcie_host_init(), where it can be properly sequenced with PERST#.

  2. Moving imx_pcie_assert_perst() before regulator and clock enable to
     ensure correct ordering.

Subject: [PATCH 1089/5214] PCI: imx6: Parse 'reset-gpios' in Root Port nodes

The current DT binding for pci-imx6 specifies the 'reset-gpios' property
in the host bridge node. However, the PERST# signal logically belongs to
individual Root Ports rather than the host bridge itself. This becomes
important when supporting PCIe Key E connector and the PCI power control
framework for pci-imx6 driver, which requires properties to be specified
in Root Port nodes.

Parse 'reset-gpios' from Root Port nodes and the PCIe bridge nodes under
the Root Port using the common helper pci_host_common_parse_ports(), and
update the reset GPIO handling to use the parsed port list from
bridge->ports. To maintain DT backwards compatibility, fall back to the
legacy method of parsing the host bridge node if the reset property is not
present in the Root Port nodes.

Since now the reset GPIO is obtained with GPIOD_ASIS flag, it may be in
input mode, so use gpiod_direction_output() instead of
gpiod_set_value_cansleep() to ensure the reset GPIO is properly
configured as output before setting its value.

Subject: [PATCH 1090/5214] media: rzg2l-cru: Skip ICnMC configuration when
 ICnSVC is used

When the CRU is configured to use ICnSVC for virtual channel mapping,
as on the RZ/{G3E, V2H/P} SoC, the ICnMC register must not be
programmed.

Return early after setting up ICnSVC to avoid overriding the ICnMC
register, which is not applicable in this mode.

This prevents unintended register programming when ICnSVC is enabled.

Subject: [PATCH 1091/5214] media: rzg2l-cru: Use only frame end interrupts

On RZ/G3E the CRU driver relies on the frame end interrupt to detect the
completion of an active frame transfer when stopping DMA.

Update the driver to enable only frame end interrupts (CRUnIE2_FExE),
dropping the usage of the frame start interrupts, which is not required
for this operations flow.

Fix the interrupt status handling in the DMA stopping state by checking
the correct frame end status bits (FExS) instead of the frame start one
(FSxS). Add a dedicated CRUnINTS2_FExS() macro to reflect the actual
register bit layout and drop the now unused CRUnIE2_FSxE() and
CRUnINTS2_FSxS() macros.

This ensures that DMA stopping is triggered by the intended frame end
events and avoids incorrect interrupt handling.

Subject: [PATCH 1093/5214] media: rzg2l-cru: Use proper guard() in irq handler

The irq handler uses a scoped_guard() that covers the whole function
body.

Replace it with a more appropriate guard() and reduce the indentation.

Subject: [PATCH 1094/5214] media: rzg2l-cru: Remove locking from start/stop
 routines

The start/stop streaming routines do not need to lock the whole function
body against possible concurrent accesses to the CRU buffers or hardware
registers.

The stop function starts by disabling interrupts, and only this portion
needs to be protected not to race against a possible IRQ.

Once interrupts are disabled, nothing in the video device driver can race
and once the peripheral has been disabled we can release all pending
buffers.

are never called from an interrupt context, hence they do not need to
use the irqsave version of the spinlock primitives.

Subject: [PATCH 1097/5214] media: rz2gl-cru: Introduce a spinlock for hw
 operations

The CRU driver uses a single spinlock to protect the buffers queue and
the hardware operations.

This single spinlock is held for the whole duration of the interrupt
handler, causing all other driver's operations to freeze.

Under heavy system stress conditions with userspace not providing
buffers fast enough, this causes loss of frames.

Prepare to re-work the driver locking by introducing (but not using yet)
a new spinlock to protect the hardware registers programming.

Subject: [PATCH 1099/5214] media: rzg2l-cru: Manually track active slot number

The CRU cycles over the hardware slots where the destination address for
the next frame has to be programmed.

The RZ/G2L version of the IP has a register that tells which is the
last used slot by the hardware but, unfortunately, such register is not
available on RZ/G3E and RZ/V2H(P).

The driver currently compares the value of the AMnMADRSL/H register
which report "the memory address which the current video data was
written to" and compares it with the address programmed in the slots.

This heuristic requires a bit of book keeping and proper locking. As the
driver handles the FrameEnd interrupt, it's way easier to keep track
of the slot that has been used by ourselves with a driver variable.

Subject: [PATCH 1100/5214] media: rz2gl-cru: Return pending buffers in order

Buffers are programmed into slots in queueing order.

When returning pending buffers we can't simply start from the first slot
but we should actually iterate slots starting from the one is use. The
rzg3e_cru_irq() handler already uses 'active_slot', make rzg2l_cru_irq()
use it as well to know where to start iterating from.

As the pattern of iterating over slots in order will be used for slots
programming in the next patches, provide an helper macro to do that.

While at it, rename return_unused_buffers() to rzg2l_cru_return_buffers().

Subject: [PATCH 1101/5214] media: rzg2l-cru: Rework rzg2l_cru_fill_hw_slot()

The current implementation of rzg2l_cru_fill_hw_slot() results in the
artificial loss of frames. At present whenever a frame-complete IRQ
is received the driver fills the hardware slot that was just written
to with the address of the next buffer in the driver's queue. If the
queue is empty, that hardware slot's address is set to the address of
the scratch buffer to enable the capture loop to keep running. There
is a minimum of a two-frame delay before that slot will be written to
however, and in the intervening period userspace may queue more
buffers which could be used.

To resolve the issue rework rzg2l_cru_fill_hw_slot() so that it
iteratively fills all slots from the queue which currently do not
have a buffer assigned, until the queue is empty. The scratch
buffer is only resorted to in the event that the queue is empty and
the next slot that will be written to does not already have a buffer
assigned.

Subject: [PATCH 1102/5214] media: rzg2l-cru: Remove the 'state' variable

The cru driver uses a 'state' variable for debugging purpose in the
interrupt handler. The state is used to detect invalid usage conditions
that are not meant to happen unless the driver has a bug in handling the
stop and start conditions.

Remove the state variable which seems to be a debugging leftover.

Subject: [PATCH 1103/5214] media: rzg2l-cru: Remove debug printouts from irq

Using dev_dbg() in irq handlers to debug per-frame events is marginally
useful and possibly not the best idea, as using printk-based helpers
introduce latencies that impact the drivers operations.

If any tracing/debugging has to be performed around frame events
in interrupt handlers, the tracing subsystem offers better alternatives.

Drop dev_dgb() calls from the CRU interrupt handlers.

Subject: [PATCH 1105/5214] media: rzv2h-ivc: Wait for frame end in
 stop_streaming

The rzv2h-ivc driver fails to handle back-2-back streaming sessions that
do not go through a peripheral reset. As the driver uses an autosuspend
delay of 2 seconds, it is quite possible that two consecutive streaming
sessions won't go through a suspend/resume sequence.

If the peripheral is not reset the second streaming session hangs and no
frames are delivered to the ISP.

This is because the stop_streaming() procedure implemented in the driver
doesn't match what's prescribed by the chip datasheet:

1) The chip manual suggests to poll the RZV2H_IVC_FM_INT_STAT_STPEND bit
   of RZV2H_IVC_REG_FM_INT_STA instead of polling on RZV2H_IVC_REG_FM_STOP
   and prescribes to clear the bit after polling has completed

2) More importantly: the RZV2H_IVC_REG_FM_STOP_FSTOP bit has to be set
   on RZV2H_IVC_REG_FM_STOP -only- if a frame transfer to the ISP is in
   progress. Setting the RZV2H_IVC_REG_FM_STOP_FSTOP bit when no frame is
   being transferred causes the polling routine to timeout and the next
   streaming session fails to start

As a frame transfer of an image in 1920x1080@10bi takes 5 milliseconds
at most, it is quite possible that the frame transfer completion interrupt
races with the stop procedure.

Instead of forcing a frame transfer abort, simply wait for the
in-progress transfer to complete by polling the ivc->vvalid_ifp status
variable in an hand-rolled loop that allows to inspect the variable
while holding the spinlock, to allow the irq handler to complete the
current buffer.

With this change, streaming back-2-back without suspending the
peripheral works successfully.

Subject: [PATCH 1109/5214] media: mali-c55: Fix possible ERR_PTR in
 enable_streams

The media_pad_remote_pad_unique() function returns either a valid
pointer or an ERR_PTR() on failure (-ENOTUNIQ if multiple links are
enabled, -ENOLINK if no connected pad is found). The return value
was assigned directly to isp->remote_src and dereferenced in the
next line without checking for errors, which could lead to an
ERR_PTR dereference.

Add proper error checking with IS_ERR() before dereferencing the
pointer. Also set isp->remote_src to NULL on error to maintain
consistency with other error paths in the function.

Subject: [PATCH 1110/5214] media: mali-c55: Add missing
 of_reserved_mem_device_release()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

mali_c55_probe() calls of_reserved_mem_device_init() to associate
reserved memory regions with the device. This function allocates a
struct rmem_assigned_device and adds it to a global linked list, which
must be explicitly released via of_reserved_mem_device_release() — there
is no devm variant of this API.

However, neither the probe error paths nor mali_c55_remove() called
of_reserved_mem_device_release(). Any probe failure after the
of_reserved_mem_device_init() call, as well as every normal device
removal, leaked the reserved memory association on the global list.

Fix this by adding an err_release_mem label at the end of the probe
error chain and calling of_reserved_mem_device_release() in
mali_c55_remove(). The remove teardown order is also corrected to call
mali_c55_media_frameworks_deinit() before kfree(), mirroring the probe
init order in reverse.

Subject: [PATCH 1111/5214] media: mali-c55: Power-off the peripheral in
 remove()

The Mali C55 driver doesn't depend on PM. For this reason, if pm_runtime
is not compiled in it is required to manually power-off the peripheral
during the driver's remove() handler.

Also pm_runtime_enable() is called during probe but mali_c55_remove()
never calls pm_runtime_disable(), leaving the device's runtime PM state
enabled after the driver is unbound.

Manually power-off the peripheral in remove() if the peripheral has not
been suspended using runtime_pm and disable runtime pm.

Subject: [PATCH 1112/5214] media: mali-c55: Disable pm_runtime on probe error

When mali_c55_media_frameworks_init() fails, the goto target jumps to
err_free_context_registers, skipping pm_runtime_disable() despite
pm_runtime having already been enabled earlier in the function.

Fix this by adding an err_pm_runtime_disable label and redirecting the
frameworks init failure to it, so pm_runtime is properly unwound on
that error path. The runtime PM status is also set back to suspended
before disabling, to undo the pm_runtime_set_active() from probe.

Subject: [PATCH 1113/5214] phy: qcom: qmp-combo: Move pipe_clk on/off to
 common

Keep the USB pipe clock working when the phy is in DP-only mode, because
the dwc controller still needs it for USB 2.0 over the same Type-C port.

Tested with the BenQ RD280UA monitor which has a downstream-facing port
for data passthrough that's manually switchable between USB 2 and 3,
corresponding to 4-lane and 2-lane DP respectively.

Note: the suspend/resume callbacks were already gating the enable/disable
of this clock only on init_count and not usb_init_count!

Subject: [PATCH 1115/5214] phy: rockchip: naneng-combphy: Consolidate SSC
 configuration

The PCIe SSC configuration for the RK3588 and RK3576 SoCs required
additional tuning which is missing. When adding these same SSC
configurations for both of these two SoCs, as well as upcoming
platforms, it's obvious the SSC setup code was largely duplicated
across the platform-specific configuration functions. This becomes
harder to maintain as more platforms are added.

So extract the common SSC logic into a shared helper function,
rk_combphy_common_cfg_ssc(). This cleans up the per-platform drivers
and centralizes the standard configuration as possible.

Subject: [PATCH 1118/5214] phy: ti: add PHY driver for TI DS125DF111
 Dual-Channel Retimer

Add a generic PHY driver for the TI DS125DF111 Multi-Protocol
Dual-Channel Retimer. The driver currently supports only 10G and 1G link
speeds but it can easily extended to also cover other usecases.

Since the available datasheet (https://www.ti.com/lit/gpn/DS125DF111)
does not name the registers, the name for the macros were determined by
their usage pattern.

A PHY device is created for each of the two channels present on the
retimer. This allows for independent configuration of the two channels.
This capability is especially important on retimers which have more than
2 channels that can be, depending on the board design, connected in
multiple different ways to the SerDes lanes.

 versions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add changes to support new ranking table version. Version 2 of the
heterogeneous ranking table provides static CPU rankings. Version 3 adds
dynamic ranking table support on newer AMD platforms. These changes ensure
that platforms still reporting version 2 continue to function with the
existing static ranking path, avoiding regressions on older hardware
that does not supply a dynamic ranking table.

Subject: [PATCH 1121/5214] ipmi:kcs: Reduce the number of retries

The retry count was initially set to 10, which with the 5 second
timeouts give 55 seconds to fail a message.

The IPMI spec specifies the 5 second timeout, and it specifies retries
for KCS but does not specify a number.  55 seconds is a long time, so
reduce retries to 2.  It matches the default in the BT state machine.
This is 15 seconds, then, which is still a long time, but more
reasonable.

Subject: [PATCH 1126/5214] media: include/uapi/linux/cec*: clarify which msgs
 are CEC 2.0

Drop comments about CEC 2.0 from cec-funcs.h.

In cec.h clearly comment messages that are CEC 2.0 specific
as such. Also rename references to HDMI 2.0 to CEC 2.0.

The <Request/Report Current Latency> messages were marked
as CEC 2.0 only. That is wrong, these messages are explicitly
allowed for any CEC version.

Subject: [PATCH 1127/5214] platform/x86: int3472: Rename daisy-chain GPIO
 props to generic

Rename the MSI-specific daisy-chain GPIO properties and software node
to generic names so they can be reused by other platforms that also
require daisy-chain GPIO configuration for TPS68470.

The OV13B10 sensor driver currently handles a single regulator called
avdd, however the sensor can be supplied by up to three regulators.
Update the driver to handle all of them together using the regulator
bulk API.

Subject: [PATCH 1131/5214] media: platform: amd: add DRM_AMDGPU dependency

With DRM_AMDGPU=m and DRM_AMD_ISP=y, it is possible to configura
VIDEO_AMD_ISP4_CAPTURE as built-in, but that fails to link:

aarch64-linux-ld: drivers/media/platform/amd/isp4/isp4_interface.o: in function `isp4if_gpu_mem_alloc.isra.0':
isp4_interface.c:(.text+0x1d0): undefined reference to `isp_kernel_buffer_alloc'
aarch64-linux-ld: drivers/media/platform/amd/isp4/isp4_interface.o: in function `isp4if_dealloc_fw_gpumem':
isp4_interface.c:(.text+0x26c): undefined reference to `isp_kernel_buffer_free'

Add a dependency on the tristate DRM_AMDGPU symbol in addition to
the boolean DRM_AMD_ISP=y, so this can only be built-in if
the ISP driver is also linked into the kernel itself.

Subject: [PATCH 1133/5214] 9p: use kvzalloc for readdir buffer

The readdir buffer is sized to msize, so kzalloc() can fail under
fragmentation with a page allocation failure in v9fs_alloc_rdir_buf()
/ v9fs_dir_readdir_dotl().

The buffer is only a response sink and is never pack_sg_list()'d,
so kvzalloc() is safe for all transports, unlike the fcall buffers
fixed in e21d451a82f3 ("9p: Use kvmalloc for message buffers on
supported transports").

Subject: [PATCH 1134/5214] 9p: invalidate readdir buffer on seek

The per-fid readdir buffer (fid->rdir) is populated lazily and only
refilled when fully drained (rdir->head == rdir->tail). userspace
lseek() on a directory fd updates file->f_pos via generic_file_llseek()
but does not touch the cached buffer, so the next getdents() iterates
the stale cache and emits entries from the previous position instead
of the one the caller asked for.

Track the file position the cached data corresponds to in
struct p9_rdir, and drop the cache on entry to iterate_shared when it
no longer matches ctx->pos. The 9p protocol's Tread/Treaddir already
take an arbitrary offset on every request, so a refill at the new
position is always legal; no .llseek override or seek restriction is
needed.

Subject: [PATCH 1137/5214] thunderbolt: Allow service drivers to specify their
 own properties

The XDomain properties can be useful for service drivers, for example to
implement a registry for the services they expose. So far there has been
no need for service drivers to specify these but with the USB4STREAM
driver that we are going to use them.

This adds remote and local side properties that the service drivers have
access to. Remote side is read-only but the local side can be changed by
a service driver. Also provide a mechanism to notify the remote side
that there are changes.

Subject: [PATCH 1143/5214] thunderbolt: Add support for USB4STREAM

Introduce USB4STREAM protocol and Linux implementation. This allows two
(or more) hosts to transfer data directly over Thunderbolt/USB4 cable
through a character device without need to go through the network stack.

Any application that supports read(2) and write(2) in some form should
be able to use the device without changes. The data is sent out to the
other side over a tunnel inside Thunderbolt/USB4 fabric. The character
device is called /dev/tbstreamX where X is the minor number starting
from 0.

All stream devices need to be configured first. This is done through
ConfigFS interface. There can be multiple streams at the same time (this
depends on number of DMA rings and available HopIDs) and a single stream
supports traffic in both directions. For example there could be an
application that uses one stream as control channel and another one as
bi-directional data channel.

A real use-case for this is to take a backup as a part of recovery
initramfs tooling (no need to setup networking or have ssh or similar
tooling as part of the initramfs). Say we want to backup the disk of
host1 to host2. First Thunderbolt/USB4 cable is connected between the
hosts (there can be devices in the middle too) then the receiving side
configures the stream:

  host2 # mkdir /sys/kernel/config/thunderbolt/stream/0-1.0
  host2 # mkdir /sys/kernel/config/thunderbolt/stream/0-1.0/backup
  host2 # echo -1 > /sys/kernel/config/thunderbolt/stream/0-1.0/backup/in_hopid
  host2 # echo -1 > /sys/kernel/config/thunderbolt/stream/0-1.0/backup/out_hopid

We use automatic HopID allocation (writing -1 to HopIDs) for simplicity.
From this point forward the /dev/tbstream0 can be used pretty much as
regular file:

  host2 # dd if=/dev/tbstream0 of=/tmp/host1.nvme0n1.backup-$(date +%F) bs=256k

The host that is being backed up then configures the stream accordingly:

  host1 # mkdir /sys/kernel/config/thunderbolt/stream/0-503.0
  host1 # mkdir /sys/kernel/config/thunderbolt/stream/0-503.0/backup

Here we take advantage of the fact that host2 also announces the active
streams through XDomain properties so the name "backup" gives us the
HopIDs. It is also possible to configure them manually in the same way
we did for host2.

Then it is just a matter of copying the data over:

  host1 # dd if=/dev/nvme0n1 of=/dev/tbstream0 bs=256k

Similarly it is possible to transfer parts of the filesystem. For
example copy contents of mydir over to the host2:

  host2 # gunzip < /dev/tbstream0 | tar xf -
  host1 # tar cf - mydir | gzip > /dev/tbstream0

Other end of the spectrum use-case is "borrowing" laptop (host1) camera
to desktop (host2):

  host2 # gst-launch-1.0 filesrc location=/dev/tbstream0 ! jpegdec ! videoconvert ! \
                         autovideosink

  host1 # gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=1920,height=1080 ! \
                         jpegenc quality=90 ! filesink location=/dev/tbstream0

Once the streams are no longer needed they can be removed:

  host1 # cd /sys/kernel/config/thunderbolt/stream/
  host1 # rmdir -p 0-503.0/backup

  host2 # cd /sys/kernel/config/thunderbolt/stream
  host2 # rmdir -p 0-1.0/backup

+ *
+ * End-to-end flow control is mandatory on both sides.
+ *
+ * Data is sent to the other side as tunneled DATA packets. All the data

+ *
+ * Once the stream device is closed, a CLOSE packet is sent to the peer
+ * so it can take the necessary action. On Linux this typically results

+ * Tunneled packet types:

+ * +-------+---------+------------------+
+ * |  PDF  |  Type   | Payload size     |

+ * |   3   | CLOSE   | up to 256 bytes  |
+ * +-------+---------+------------------+
+ *
+ * Each stream can optionally publish configuration values under its own
+ * XDomain property directory. The name of the directory is the name of
+ * the stream in question and the UUID is up to the stream. For example

+Streaming data directly over Thunderbolt cable
+----------------------------------------------
+In addition to Thunderbolt networking (aka. USB4NET) Linux supports
+streaming data directly over a cable as well (aka. USB4STREAM). This is
+possible through ``thunderbolt-stream`` driver.
+
+Similarly to ``thunderbolt-net`` you load the driver first on one end::
+
+  host1 # modprobe thunderbolt-stream
+
+Then you configure it via ``ConfigFS``::
+
+  host1 # cd /sys/kernel/config/thunderbolt/stream
+  host1 # mkdir -p 0-1.0/data
+  host1 # cd 0-1.0
+  host1 # echo -1 > data/in_hopid
+  host1 # echo -1 > data/out_hopid
+
+This information is automatically announced to the other side via
+XDomain properties so if you have cable connected the other side knows
+that there is a stream named ``data`` available and can configure it for
+you automatically::
+
+  host2 # cd /sys/kernel/config/thunderbolt/stream
+  host2 # mkdir -p 0-3.0/data
+
+Here we used auto-configuration but you can configure it manually too.
+In that case you need to fill ``in_hopid`` and ``out_hopid`` accordingly.
+If you set them to ``-1`` the next available HopID is used which is
+typically what we want.
+
+Once they are configured you can use ``/dev/tbstreamX`` on both sides to
+transfer data::
+
+  host2 # cat /dev/tbstream0
+  host1 # dmesg > /dev/tbstream0
+
+Once you are done with the stream you can remove them::
+
+  host2 # cd /sys/kernel/config/thunderbolt/stream
+  host2 # rmdir -p 0-1.0/data
+  host1 # cd /sys/kernel/config/thunderbolt/stream
+  host1 # rmdir -p 0-3.0/data
+
+Since streams are essentially files you can use any existing application
+that supports ``read(2)`` and ``write(2)`` in some form.
+
+It is possible to have more than one stream and you can have both stream
+and ``thunderbolt-net`` in use simultaneously. For example we can create
+two streams with name ``control`` and ``data`` like this::
+
+  host1 # cd /sys/kernel/config/thunderbolt/stream
+  host1 # mkdir 0-1.0
+  host1 # cd 0-1.0
+  host1 # mkdir control
+  host1 # mkdir data
+
+Then you have ``/dev/tbstream0`` for ``control`` and ``/dev/tbstream1``
+for ``data``. Before you can use them you need to configure them as
+shown above for the one stream case.

Subject: [PATCH 1145/5214] coresight: platform: defer connection counter
 increment until alloc succeeds

coresight_add_out_conn() increments nr_outconns before calling
devm_krealloc_array() and again before devm_kmalloc(). If either
allocation fails, the counter is already bumped while the corresponding
array entry is NULL or uninitialized garbage.

coresight_add_in_conn() has the same problem with nr_inconns and
devm_krealloc_array().

In both cases the probe returns -ENOMEM, which causes
coresight_get_platform_data() to call coresight_release_platform_data()
for cleanup. That function iterates up to nr_outconns (or nr_inconns)
entries and dereferences each pointer unconditionally, hitting the NULL
or garbage entry and panicking instead of failing gracefully.

Fix by moving the counter increments to after all allocations succeed,
so the struct is always consistent on any error path.

The kstrtou32() function returns negative error code or zero on success.
However, in this case "val" is a u32 and the function returns signed long,
so negative error codes from kstrtou32() are returned as high positive

 system_dfl_long_wq
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the code enqueue work items using {queue|mod}_delayed_work(),
using system_long_wq. This workqueue should be used when long works are
expected and it is a per-cpu workqueue.

The function(s) end up calling __queue_delayed_work(), which set a global
timer that could fire anywhere, enqueuing the work where the timer fired.

Unbound works could benefit from scheduler task placement, to optimize
performance and power consumption. Long work shouldn't stick to a single
CPU.

Recently, a new unbound workqueue specific for long running work has
been added:

    c116737e972e ("workqueue: Add system_dfl_long_wq for long unbound works")

Since the workqueue work doesn't rely on per-cpu variables, there is no
obvious reason that justify the use of a per-cpu workqueue. So change
system_long_wq with system_dfl_long_wq so that the work may benefit from
scheduler task placement.

Subject: [PATCH 1151/5214] dt-bindings: dma: qcom,bam-dma: Document BAM v2.0.0
 compatible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Document compatible string for bam v2.0.0 version found on kaanapali.
BAM v2.0.0 differs from the earlier v1.7.X revision in terms of register
layout and offsets, requiring a distinct compatible for correct hardware
description.

Also add a new example for BAM v2.0.0 to illustrate a more complete
configuration than the existing v1.4 example. The new example covers
64-bit address and size cells, IOMMU bindings and execution
environment–related properties required on newer platforms.

Subject: [PATCH 1154/5214] dt-bindings: dmaengine: Add SpacemiT K3 DMA
 compatible string

Add the "spacemit,k3-pdma" compatible string for the SpacemiT K3 SoC.

While the K3 PDMA IP reuses most of the design found on the earlier
K1 SoC, a new compatible string is required because the DRCMR
(DMA Request/Command Register) base address for extended DMA request
numbers (>= 64) differs from the K1 implementation.

Subject: [PATCH 1158/5214] dmaengine: Move MODULE_DEVICE_TABLE next to the
 table itself

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it
exports, because this is easier to read and verify.  It also makes more
sense since #ifdef for ACPI or OF could hide both of them.

Most of the drivers already have this correctly placed, so adjust
the missing ones.  No functional impact.

Subject: [PATCH 1159/5214] ipmi: Use named initializers for struct
 i2c_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

While touching these arrays, unify usage of whitespace in the list
terminator.

Subject: [PATCH 1160/5214] PCI: loongson: Override PCIe bridge supported
 speeds for Loongson-3C6000 series

Older steppings of the Loongson-3C6000 series incorrectly report the
supported link speeds on their PCIe bridges (device IDs 0x3c19, 0x3c29)
as only 2.5 GT/s, despite the upstream bus supporting speeds from
2.5 GT/s up to 16 GT/s.

As a result, since commit 774c71c52aa4 ("PCI/bwctrl: Enable only if more
than one speed is supported"), bwctrl will be disabled if there's only
one 2.5 GT/s value in vector 'supported_speeds'.

Manually override the 'supported_speeds' field for affected PCIe bridges
with those found on the upstream bus to correctly reflect the supported
link speeds.  Updating the speeds to reflect what the hardware actually
supports avoids quirks in drivers consuming the speed information.

This commit was originally found from AOSC OS[1].

Subject: [PATCH 1161/5214] powerpc: rename arch_irq_disabled_regs

Rename arch_irq_disabled_regs() to regs_irqs_disabled() to align with the
naming used in the generic irqentry framework. This makes the function
available for use both in the PowerPC architecture code and in the
common entry/exit paths shared with other architectures.

This is a preparatory change for enabling the generic irqentry framework
on PowerPC.

Subject: [PATCH 1162/5214] powerpc: Prepare to build with generic entry/exit
 framework
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch introduces preparatory changes needed to support building
PowerPC with the generic entry/exit (irqentry) framework.

The following infrastructure updates are added:
 - Add a syscall_work field to struct thread_info to hold SYSCALL_WORK_* flags.
 - Provide a stub implementation of arch_syscall_is_vdso_sigreturn(),
   returning false for now.
 - Introduce on_thread_stack() helper to detect if the current stack pointer
   lies within the task’s kernel stack.

These additions enable later integration with the generic entry/exit
infrastructure while keeping existing PowerPC behavior unchanged.

No functional change is intended in this patch.

Subject: [PATCH 1163/5214] powerpc: introduce arch_enter_from_user_mode

Implement the arch_enter_from_user_mode() hook required by the generic
entry/exit framework. This helper prepares the CPU state when entering
the kernel from userspace, ensuring correct handling of KUAP/KUEP,
transactional memory, and debug register state.

This patch contains no functional changes, it is purely preparatory for
enabling the generic syscall and interrupt entry path on PowerPC.

Subject: [PATCH 1164/5214] powerpc: Introduce syscall exit arch functions

Add PowerPC-specific implementations of the generic syscall exit hooks
used by the generic entry/exit framework:

 - arch_exit_to_user_mode_work_prepare()
 - arch_exit_to_user_mode_work()

These helpers handle user state restoration when returning from the
kernel to userspace, including FPU/VMX/VSX state, transactional memory,
KUAP restore, and per-CPU accounting.

Additionally, move check_return_regs_valid() from interrupt.c to
interrupt.h so it can be shared by the new entry/exit logic.

No functional change is intended with this patch.

Subject: [PATCH 1165/5214] powerpc: add exit_flags field in pt_regs

Add a new field `exit_flags` in the pt_regs structure. This field will hold
the flags set during interrupt or syscall execution that are required during
exit to user mode.

Specifically, the `TIF_RESTOREALL` flag, stored in this field, helps the
exit routine determine if any NVGPRs were modified and need to be restored
before returning to userspace.

This addition ensures a clean and architecture-specific mechanism to track
per-syscall or per-interrupt state transitions related to register restore.

Changes:
 - Add `exit_flags` and `__pt_regs_pad` to maintain 16-byte stack alignment
 - Update asm-offsets.c and ptrace.c for offset and validation
 - Update PT_* constants in uapi header to reflect the new layout

Subject: [PATCH 1166/5214] powerpc: Prepare for IRQ entry exit

Move interrupt entry and exit helper routines from interrupt.h into the
PowerPC-specific entry-common.h header as a preparatory step for enabling
the generic entry/exit framework.

This consolidation places all PowerPC interrupt entry/exit handling in a
single common header, aligning with the generic entry infrastructure.
The helpers provide architecture-specific handling for interrupt and NMI
entry/exit sequences, including:

 - arch_interrupt_enter/exit_prepare()
 - arch_interrupt_async_enter/exit_prepare()
 - arch_interrupt_nmi_enter/exit_prepare()
 - Supporting helpers such as nap_adjust_return(), check_return_regs_valid(),
   debug register maintenance, and soft mask handling.

The functions are copied verbatim from interrupt.h.Subsequent patches will
integrate these routines into the generic entry/exit flow.

No functional change intended.

Subject: [PATCH 1167/5214] powerpc: Enable GENERIC_ENTRY feature
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enable the generic IRQ entry/exit infrastructure on PowerPC by selecting
GENERIC_ENTRY and integrating the architecture-specific interrupt and
syscall handlers with the generic entry/exit APIs.

This change replaces PowerPC’s local interrupt entry/exit handling with
calls to the generic irqentry_* helpers, aligning the architecture with
the common kernel entry model. The macros that define interrupt, async,
and NMI handlers are updated to use irqentry_enter()/irqentry_exit()
and irqentry_nmi_enter()/irqentry_nmi_exit() where applicable also
convert the PowerPC syscall entry and exit paths to use the generic
entry/exit framework and integrating with the common syscall handling
routines.

Key updates include:
 - The architecture now selects GENERIC_ENTRY in Kconfig.
 - Replace interrupt_enter/exit_prepare() with arch_interrupt_* helpers.
 - Integrate irqentry_enter()/exit() in standard and async interrupt paths.
 - Integrate irqentry_nmi_enter()/exit() in NMI handlers.
 - Remove redundant irq_enter()/irq_exit() calls now handled generically.
 - Use irqentry_exit_cond_resched() for preemption checks.
 - interrupt.c and syscall.c are simplified to delegate context
   management and user exit handling to the generic entry path.
 - The new pt_regs field `exit_flags` introduced earlier is now used
   to carry per-syscall exit state flags (e.g. _TIF_RESTOREALL).
 - Remove unused code.

This change establishes the necessary wiring for PowerPC to use the
generic IRQ entry/exit framework while maintaining existing semantics.
This aligns PowerPC with the common entry code used by other
architectures and reduces duplicated logic around syscall tracing,
context tracking, and signal handling.

The performance benchmarks from perf bench basic syscall are below:

perf bench syscall usec/op (-ve is improvement)

| Syscall | Base        | test        | change % |
| ------- | ----------- | ----------- | -------- |
| basic   | 0.093543    | 0.093023    | -0.56    |
| execve  | 446.557781  | 450.107172  | +0.79    |
| fork    | 1142.204391 | 1156.377214 | +1.24    |
| getpgid | 0.097666    | 0.092677    | -5.11    |

perf bench syscall ops/sec (+ve is improvement)

| Syscall | Base     | New      | change % |
| ------- | -------- | -------- | -------- |
| basic   | 10690548 | 10750140 | +0.56    |
| execve  | 2239     | 2221     | -0.80    |
| fork    | 875      | 864      | -1.26    |
| getpgid | 10239026 | 10790324 | +5.38    |

IPI latency benchmark (-ve is improvement)

| Metric         | Base (ns)     | New (ns)      | % Change |
| -------------- | ------------- | ------------- | -------- |
| Dry run        | 583136.56     | 584136.35     | 0.17%    |
| Self IPI       | 4167393.42    | 4149093.90    | -0.44%   |
| Normal IPI     | 61769347.82   | 61753728.39   | -0.03%   |
| Broadcast IPI  | 2235584825.02 | 2227521401.45 | -0.36%   |
| Broadcast lock | 2164964433.31 | 2125658641.76 | -1.82%   |

Thats very close to performance earlier with arch specific handling.

Subject: [PATCH 1169/5214] media: pwc: Drain fill_buf on start_streaming()
 failure

pwc_isoc_init() submits its isochronous URBs with
usb_submit_urb(.., GFP_KERNEL) in a loop. After the first URB is
submitted, its completion handler pwc_isoc_handler() can run on another
CPU before the loop finishes:

  start_streaming()
    pwc_isoc_init()
      usb_submit_urb(urbs[0], GFP_KERNEL)
                                  pwc_isoc_handler(urbs[0])
                                    pdev->fill_buf =
                                      pwc_get_next_fill_buf(pdev)
      usb_submit_urb(urbs[i>0], ..)  -> fails
      pwc_isoc_cleanup(pdev)           /* kills URBs */
      return ret;
    pwc_cleanup_queued_bufs(pdev, VB2_BUF_STATE_QUEUED)

pwc_get_next_fill_buf() detaches a buffer from pdev->queued_bufs and
stores it in pdev->fill_buf. The error path in start_streaming() only
drains pdev->queued_bufs, so the buffer parked in pdev->fill_buf is
leaked. vb2_start_streaming() then triggers
WARN_ON(owned_by_drv_count).

stop_streaming() already handles this since commit 80b0963e1698
("[media] pwc: fix WARN_ON"), which added the fill_buf drain in the
teardown path but not in the start_streaming() error path. Mirror that
handling on failure so start_streaming() returns with no buffer owned
by the driver.

Issue identified by automated review of the INV-003 series at
https://sashiko.dev/

Subject: [PATCH 1170/5214] media: radio-si476x: Unregister v4l2_device on
 probe failure

si476x_radio_probe() registers radio->v4l2dev before allocating the V4L2
controls and before registering the video device. If any of those later
steps fails, probe returns through the exit label after freeing only the
control handler.

A failed probe does not call si476x_radio_remove(), so the
v4l2_device_unregister() there is not reached. This leaves the parent
device reference taken by v4l2_device_register() behind on the error path.

Unregister the V4L2 device in the probe error path after freeing the
controls.

-The Atmel ISC driver is not compliant with media controller specification.
-In order to evolve this driver, it has to move to media controller, to
-support enhanced features and future products which embed it.
-The move to media controller involves several changes which are
-not backwards compatible with the current usability of the driver.
-
-The best example is the way the format is propagated from the top video
-driver /dev/videoX down to the sensor.
-
-In a simple configuration sensor ==> isc , the isc just calls subdev s_fmt
-and controls the sensor directly. This is achieved by having a lot of code
-inside the driver that will query the subdev at probe time and make a list
-of formats which are usable.
-Basically the user has nothing to configure, as the isc will handle
-everything at the top level. This is an easy way to capture, but also comes
-with the drawback of lack of flexibility.
-In a more complicated pipeline
-sensor ==> controller 1 ==> controller 2 ==> isc
-this will not be achievable, as controller 1 and controller 2 might be
-media-controller configurable, and will not propagate the formats down to
-the sensor.
-
-After discussions with the media maintainers, the decision is to move
-Atmel ISC to staging as-is, to keep the Kconfig symbols and the users
-to the driver in staging. Thus, all the existing users of the non
-media-controller paradigm will continue to be happy and use the old config
-way.
-
-The new driver was added in the media subsystem with a different
-symbol, with the conversion to media controller done, and new users
-of the driver will be able to use all the new features.
-
-The replacement driver is named VIDEO_MICROCHIP_ISC or
-VIDEO_MICROCHIP_XISC depending on the product flavor.

Subject: [PATCH 1173/5214] media: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace and commas.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 1175/5214] staging: media: atomisp: replace sprintf() with
 strscpy()

Auditing calls to sprintf(). This code is fine because we are
copying 9 characters into a 52 character buffer. But it would
be cleaner to use strscpy() instead. Additionally, the 2-argument
version of strscpy() checks at compile time that dst is an array,
not just a pointer.

This is the only sprintf() call in the whole driver.

Subject: [PATCH 1179/5214] staging: media: atomisp: Fix typos and formatting
 in headers

Update block and inline comments to follow kernel
commenting conventions, fix typos and wording, remove
redundant comments and reformat long comments for clarity
and line length consistency.

Although some comments used the /** ... */ style, they are not
kernel-doc comments and are converted to normal comment style.

No functional changes are intended.

Subject: [PATCH 1183/5214] media: atomisp: Fix memory leak in
 atomisp_fixed_pattern_table()

atomisp_v4l2_framebuffer_to_css_frame() allocates memory for
temporary variable raw_black_frame, which must be released via
ia_css_frame_free() before the function returns. However, if
sh_css_set_black_frame() fails, the function returns immediately without
performing this cleanup, leading to a memory leak.

Fix this by assigning the return value of sh_css_set_black_frame() to
ret. This ensures that the error code is propagated while allowing the
execution to fall through to the ia_css_frame_free() cleanup call.

The bug was originally detected on v6.13-rc1 using an experimental
static analysis tool we are developing, and we have verified that the
issue persists in the latest mainline kernel. The tool is based on the
LLVM framework and is specifically designed to detect memory management
issues. It is currently under active development and not yet publicly
available.

We performed build testing on x86_64 with allyesconfig. Since triggering
this error path in atomisp requires specific Intel Atom ISP hardware and
firmware, we were unable to perform runtime testing and instead verified
the fix according to the code logic.

Subject: [PATCH 1184/5214] media: atomisp: Fix alloc_pages_bulk() failed
 errors

Systems with the atomisp ISP do not have a lot of memory for modern
standards, so these are often under memory pressure and alloc_pages_bulk()
does not try very hard to free pages before returning an amount of pages
which is less then requested. This leads to streaming from the camera
often failing with a "alloc_pages_bulk() failed" error.

vmalloc() also uses alloc_pages_bulk(), but falls back to allocating one
page at a time when that fails.

Do the same in alloc_private_pages() to avoid these errors.

While at it also drop the weird custom GFP flags and just use GFP_KERNEL
and drop the dev_err() as alloc_pages() already complaints loudly if
it fails itself.

Subject: [PATCH 1190/5214] media: atomisp: Fix block comment coding style in
 sh_css_param_shading.c

Fix checkpatch.pl warnings in sh_css_param_shading.c regarding block
comment formatting.

The warning was:
- Block comments use a trailing */ on a separate line

This change also moves text from the first line of block comments to
subsequent lines to adhere to the standard Linux kernel coding style.

Subject: [PATCH 1191/5214] media: atomisp: replace ia_css_region with
 v4l2_rect

The struct ia_css_region definition is redundant as struct v4l2_rect
provides the same functionality (left, top, width, height) and is the
standard V4L2 type.

Replace usage of ia_css_region with v4l2_rect in ia_css_dz_config
and remove the definition of ia_css_region from ia_css_types.h.

Also remove historical comments referencing the addition of zoom_region
and include <linux/videodev2.h> to support the v4l2_rect type.

Subject: [PATCH 1192/5214] media: atomisp: gc2235: fix UAF and memory leak

gc2235_probe() handles its error paths incorrectly.

If media_entity_pads_init() fails, gc2235_remove() is called, which
tears down the subdev and frees dev, but then still falls through to
atomisp_register_i2c_module(). This results in use-after-free.

If atomisp_register_i2c_module() fails, the media entity and control
handler are left initialized and dev is leaked.

gc2235_remove() unconditionally calls media_entity_cleanup() and
v4l2_ctrl_handler_free(), but these are not initialized at every
error path in gc2235_probe().

Replace gc2235_remove() calls in the probe error paths with explicit
unwind labels that free only the resources initialized at each point
of failure, in reverse order of initialization.

Subject: [PATCH 1195/5214] media: atomisp: gate ref and tnr frame config
 behind ISP enable flags

The FIXME comment noted that delay_frames can be NULL for certain
pipeline configurations, without knowing why. The reason is that when a
binary does not enable ref_frame, delay frame allocation is
intentionally skipped to save memory, leaving the pointers NULL by
design.

The ISP feature flags in binary->info->sp.enable accurately reflect
which features are active for a given binary. Using enable.ref_frame and
enable.tnr as the predicate for their respective configuration steps
ensures the configuration path stays in sync with what was actually
built into the pipeline

Subject: [PATCH 1196/5214] media: atomisp: remove redundant call to
 ia_css_output0_configure()

The function configure_isp_from_args() contained a duplicate call to
ia_css_output0_configure() using the same output frame index. Remove the
redundant call to simplify the configuration path.

The ia_css_output0_configure() function acts as a configuration setter.
It populates a struct ia_css_output0_configuration from the frame info
and caches it in the binary parameters. Calling it twice with the same
out_frame[0] pointer merely overwrites the exact same state with
identical values. It has no cumulative state, neither does its order
matter relative to ia_css_copy_output_configure().

ia_css_configure_output0() writes into binary->mem_params.params[], a
software-side DMEM parameter buffer in kernel memory. The ISP firmware
receives these parameters later as a batch, not at the time of the call.
Calling a pure memory write twice with the same pointer and same value
simply overwrites the same location with identical data, there is no
hardware interaction that could require repetition.

Subject: [PATCH 1201/5214] staging: media: atomisp: improve cleanup robustness
 in ia_css_stream_destroy_isp2401()

Remove the 'assert(entry)' call. In the atomisp driver, assert() is a
wrapper around BUG(), which intentionally crashes the entire kernel.
This is dangerous and inappropriate for a simple null pointer check
during stream teardown. Replace it with a safe 'if (!entry) continue;'
check.

Change the early 'return' to a 'continue'. In a destruction
path, it is better to proceed with cleaning up as many resources as
possible rather than aborting early, which would result in memory leaks
for the remaining pipes.

Subject: [PATCH 1202/5214] thunderbolt: Improve multi-display DisplayPort
 tunnel allocation

When 3 monitors are connected through Thunderbolt dock to the system at
once, one of the monitors might fail to establish DisplayPort tunnel.
This happens during DP bandwidth negotiation - each monitor takes
maximum bandwidth that is supported and there might not be enough for
3rd display. In this case Thunderbolt driver drops DP tunnel and
'forgets' about it but with DP bandwidth allocation mode, that comes in
later, some bandwidth might be freed.

Make Thunderbolt driver check again if DP tunnel can be established
after DP bandwidth consumption changed.

Currently if lane bonding is not possible or not supported, we continue
and read the updated number of Total Buffers from lane adapters unnecessarily
and incorrectly log the bonding as successful.

Fix this by bailing out early when bonding is not possible, avoiding
the unnecessary read and the misleading log message.

 destination

Currently, path activation starts from the last hop (destination adapter)
and iterates backwards to the first hop (source adapter). This does not
follow the order suggested in the USB4 Connection Manager guide and could
potentially cause issues with tunnelled protocols.

Reverse the activation order to start from the first hop (source adapter)
and end at the last hop (destination adapter), as suggested in the
Connection Manager guide.
Adjust the rollback in the failure path to deactivate from the first
hop, since hops are now activated starting at the source.

Fix kernel-doc accordingly.

 ms for USB4 routers

Currently we set the Notification Timeout field in ROUTER_CS_4 for USB4
routers to 10 ms, which is unnecessarily short and may cause unnecessary
retransmissions of Hot Plug packets by the router in case of slow
software response.
Increase the timeout to 255 ms, aligning with Thunderbolt 3 routers
and providing adequate time for software to process Hot Plug Events.

 leaks on driver removal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Switch over cmpc_accel_add_v4() and cmpc_accel_add() to using
devm_kzalloc() for allocating the accel object which will cause it
to be freed automatically on device removal, so it won't be leaked
any more.

This also simplifies the rollback paths in these functions somewhat.

Content-Type: text/plain; charset=UTF-8

To facilitate subsequent conversion of the driver to using struct
platform_driver instead of struct acpi_driver, modify two helper
functions in it, cmpc_add_acpi_notify_device() and
cmpc_remove_acpi_notify_device(), to take a struct device pointer
argument instead of a struct acpi_device pointer argument and update
their callers accordingly.

While at it, change the return type of cmpc_remove_acpi_notify_device()
to void because its return value is never checked.

No intentional functional impact.

Subject: [PATCH 1215/5214] platform/x86: classmate-laptop: Rename two helper
 functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since cmpc_add_acpi_notify_device() and cmpc_remove_acpi_notify_device()
have been modified to take a plain struct device pointer as the first
argument, then have nothing to do with ACPI in principle, so rename
them to cmpc_add_notify_device() and cmpc_remove_notify_device(),
respectively, and consolidate white space around the call sites of
the former.

No intentional functional impact.

Subject: [PATCH 1217/5214] platform/x86: classmate-laptop: Convert v4 accel
 driver to a platform one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware.  Accordingly, a struct platform_driver should be
used by driver code to bind to that device.  There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].

Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert cmpc_accel_acpi_driver_v4 in the Classmate
laptop driver from an ACPI driver to a platform one.

After this change, the input device registered by the driver will
appear under the platform device used for driver binding, but the sysfs
attributes added by the driver under the ACPI companion of that device
will stay there in case there are utilities in user space expecting
them to be present there.

While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.

Subject: [PATCH 1218/5214] platform/x86: classmate-laptop: Convert accel
 driver to a platform one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware.  Accordingly, a struct platform_driver should be
used by driver code to bind to that device.  There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].

Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert cmpc_accel_acpi_driver in the Classmate
laptop driver from an ACPI driver to a platform one.

After this change, the input device registered by the driver will
appear under the platform device used for driver binding, but the sysfs
attribute added by the driver under the ACPI companion of that device
will stay there in case there are utilities in user space expecting
it to be present there.

While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.

Subject: [PATCH 1221/5214] platform/x86: classmate-laptop: Convert keys driver
 to a platform one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware.  Accordingly, a struct platform_driver should be
used by driver code to bind to that device.  There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].

Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert cmpc_keys_acpi_driver in the Classmate
laptop driver from an ACPI driver to a platform one.

After this change, the input device registered by the driver will appear
under the platform device used for driver binding.

While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.

Subject: [PATCH 1222/5214] staging: media: atomisp: reduce
 load_primary_binaries() stack usage

The load_primary_binaries() function is overly complex and has som large
variables on the stack, which can cause warnings depending on CONFIG_FRAME_WARN
setting:

drivers/staging/media/atomisp/pci/sh_css.c: In function 'load_primary_binaries':
drivers/staging/media/atomisp/pci/sh_css.c:5260:1: error: the frame size of 1560 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]

Half of the stack usage is for the prim_descr[] array, but only one
member of the array is used at any given time.

Reduce the stack usage by turning the array into a single structure.

Subject: [PATCH 1228/5214] staging: media: atomisp: use array3_size() for
 overflow-safe allocation

Replace open-coded width * height * sizeof() multiplications with
array3_size() to prevent integer overflow in buffer allocations.

The atomisp driver computes DVS, morphing table, shading table and
statistics buffer sizes using unchecked arithmetic.  When dimensions
are attacker-controlled or simply large, the product can silently wrap,
causing kvmalloc() to allocate an undersized buffer.

array3_size() saturates to SIZE_MAX on overflow, so kvmalloc() returns
NULL instead of succeeding with too few bytes.

Subject: [PATCH 1237/5214] staging: media: atomisp: fix map and vmap leaks in
 stat buffer allocation

There are memory leaks in
drivers/staging/media/atomisp/pci/atomisp_compat_css20.c.

In atomisp_css_allocate_stat_buffers(), s3a_map is allocated by
ia_css_isp_3a_statistics_map_allocate() and its backing memory is
mapped via hmm_vmap(). When dis_buf allocation fails, the error path
frees s3a_data but does not unmap or free s3a_map. Similarly, when
md_buf allocation fails, neither s3a_map nor dvs_map (and their hmm
vmaps) are freed.

Add the missing hmm_vunmap() and map free calls on both error paths,
matching the cleanup order used in atomisp_css_free_3a_buffer() and
atomisp_css_free_dis_buffer().

20ms due to timer granularity. fsleep() selects the appropriate sleep

Subject: [PATCH 1242/5214] media: i2c: alvium: fix critical pointer access in
 alvium_ctrl_init

The current implementation of alvium_ctrl_init creates several controls in
function alvium_ctrl_init and uses the returned pointer without check. That
can cause write access over NULL-pointer for several controls. The reworked
code checks the pointers before adding flags.

Subject: [PATCH 1243/5214] media: synopsys: Fix IPI using hardcoded datatype

The imx93_csi2rx_dphy_ipi_enable() function configures the IPI datatype
using csi2->formats->csi_dt, which is initialized during probe but never
updated in set_fmt(). This causes the IPI to always use the probe-time
default datatype, ignoring the actual media bus format negotiated at
runtime. When userspace requests a different format, the IPI hardware is
configured with the wrong datatype, resulting in incorrect image output.

Fix by updating csi2->formats in the set_fmt callback to reflect the
currently negotiated format, ensuring the IPI configuration matches the
runtime datatype.

The current driver only supports single stream operation. Add support
for multiple concurrent streams by tracking enabled streams with a
bitmask and only initializing the hardware once for the first stream.

This enables use cases such as surround view systems where multiple
camera streams need to be processed simultaneously through the same
CSI-2 receiver interface.

Subject: [PATCH 1247/5214] media: dt-bindings: add NXP i.MX95 compatible
 string

The i.MX95 CSI-2 controller is nearly identical to i.MX93, with the
main difference being the data output interface:

i.MX93 use IPI (Image Pixel Interface), which requires:
- Pixel clock input
- Software configuration through registers

i.MX95 uses IDI (Image Data Interface), which:
- Does not require pixel clock
- Is software transparent (no register configuration needed)

Due to these differences in register layout and initialization needs,
the two variants cannot share the same compatible string. The driver
needs to distinguish between them to handle the interface correctly.

nearly identical to i.MX93, with the main difference being the use of

However, the IDI interface is transparent to software, requiring only
a different register map definition while sharing the same PHY control
functions with i.MX93.

Subject: [PATCH 1251/5214] dt-bindings: media: ti,j721e-csi2rx-shim: Support
 32 dma chans

The CSI2RX SHIM IP can support 32x DMA channels. These can be used to
split incoming "streams" of data on the CSI-RX port, distinguished by
MIPI Virtual Channel (or Data Type), into different locations in memory.

Actual number of DMA channels allocated to CSI-RX is dependent on the
usecase, and can be modified using the K3 Resource Partitioning tool [1].
So set the minimum channels as 1 and maximum as 32.

Subject: [PATCH 1252/5214] media: ti: j721e-csi2rx: separate out device and
 context

The TI CSI2RX wrapper has two parts: the main device and the DMA
contexts. The driver was originally written with single camera capture
in mind, so only one DMA context was needed. For the sake of simplicity,
the context specific stuff was not modeled different to the main device.

To enable multiplexed stream capture, the contexts need to be separated
out from the main device. Create a struct ti_csi2rx_ctx that holds the
DMA context specific things. Separate out functions handling the device
and context related functionality.

Subject: [PATCH 1254/5214] media: ti: j721e-csi2rx: allocate DMA channel based

With multiple contexts, there needs to be a different DMA channel for
each context. Earlier, the DMA channel name was hard coded to "rx0" for
the sake of simplicity. Generate the DMA channel name based on its index
and get the channel corresponding to the context.

Subject: [PATCH 1255/5214] media: ti: j721e-csi2rx: add a subdev for the core
 device

With single stream capture, it was simpler to use the video device as
the media entity representing the main TI CSI2RX device. Now with multi
stream capture coming into the picture, the model has shifted to each
video device having a link to the main device's subdev. The routing
would then be set on this subdev.

Add this subdev, link each context to this subdev's entity and link the
subdev's entity to the source. Also add an array of media pads. It will
have one sink pad and source pads equal to the number of contexts.

Support the new enable_stream()/disable_stream() APIs in the subdev
instead of s_stream() hook.

Subject: [PATCH 1256/5214] media: cadence: csi2rx: Move to
 .enable/disable_streams API

The enable_streams() API in v4l2 supports passing a bitmask to enable
each pad/stream combination individually on any media subdev. Use this
API instead of  s_stream() API.

Implement the enable_stream and disable_stream hooks in place of the
stream-unaware s_stream hook.

Remove the lock that was used to serialize stream starts/stops which
is not required anymore since the v4l2-core serializes the
enable/disable_streams() calls for the subdev.

Subject: [PATCH 1257/5214] media: ti: j721e-csi2rx: get number of contexts
 from device tree

Different platforms that use this driver might have different number of
DMA channels allocated for CSI. So only as many DMA contexts can be used
as the number of DMA channels available. Get the number of channels
provided via device tree and only configure that many contexts, and
hence only that many pads.

Subject: [PATCH 1259/5214] media: ti: j721e-csi2rx: add support for processing
 virtual channels

Use get_frame_desc() to get the frame desc from the connected source,
and use the provided virtual channel and DT instead of defaults.

As we don't support multiple streams yet, we will just always use
stream 0. If the source doesn't support get_frame_desc(), fall back
to the previous method of always capturing virtual channel 0.

Subject: [PATCH 1260/5214] media: cadence: csi2rx: add multistream support

Cadence CSI-2 bridge IP supports capturing multiple virtual "streams"
of data over the same physical interface using MIPI Virtual Channels.

While the hardware IP supports usecases where streams coming in the sink
pad can be broadcasted to multiple source pads, the driver will need
significant re-architecture to make that possible. The two users of this
IP in mainline linux are TI Shim and StarFive JH7110 CAMSS, and both
have only integrated the first source pad i.e stream0 of this IP. So for
now keep it simple and only allow 1-to-1 mapping of streams from sink to
source, without any broadcasting.

Subject: [PATCH 1261/5214] media: ti: j721e-csi2rx: add multistream support

Each CSI2 stream can be multiplexed into 32 independent streams, each
identified by its virtual channel number and data type. The incoming
data from these streams can be filtered on the basis of either the
virtual channel or the data type.

To capture this multiplexed stream, the application needs to tell
the driver how it wants to route the data. It needs to specify
which context should process which stream. This is done via the
new routing APIs.

Add ioctls to accept routing information from the application and save
that in the driver. This can be used when starting streaming on a
context to determine which route and consequently which virtual channel
it should process.

De-assert the pixel interface reset on first start_streaming() and assert
it on the last stop_streaming().

We already make sure to submit all available buffers to DMA in each DMA
completion callback.

Move that logic in a separate function, and use it during stream start
as well, as most application queue all their buffers before stream on.

Subject: [PATCH 1263/5214] media: ti: j721e-csi2rx: Change the drain
 architecture for multistream

On buffer starvation the DMA is marked IDLE, and the stale data in the
internal FIFOs gets drained only on the next VIDIOC_QBUF call from the
userspace. This approach works fine for a single stream case.

But in multistream scenarios, buffer starvation for one stream can
block the shared HW FIFO of the CSI2RX IP. This can stall the pipeline
for all other streams, even if buffers are available for  them.

This patch introduces a new architecture, that continuously drains data
from the shared HW FIFO into a small (32KiB) buffer if no buffers are made
available to the driver from the userspace. This ensures independence
between different streams, where a slower downstream element for one
camera does not block streaming for other cameras.

Additionally, after we drain for a stream, the next frame will be a
partial frame, as a portion of its data will have already been drained
before a valid buffer is queued by user space to the driver.
Return the partial frame to user space with VB2_BUF_STATE_ERROR.

Use wait for completion barrier to make sure the shared hardware FIFO
is cleared of the data at the end of stream after the source has stopped
sending data.

Subject: [PATCH 1265/5214] media: ti: j721e-csi2rx: Support runtime suspend

Add support for runtime power-management to enable powering off the
shared power domain between Cadence CSI2RX and TI CSI2RX wrapper when
the device(s) are not in use.

When powering off the IP, the PSI-L endpoint loses the paired DMA
channels. Thus we have to release the DMA channels at runtime suspend
and request them again at resume.

Subject: [PATCH 1266/5214] media: ti: j721e-csi2rx: Support system suspend
 using pm_notifier

As this device is the "orchestrator" for the rest of the media
pipeline, we need to stop all on-going streams before system suspend and
enable them back when the system wakes up from sleep.

Using .suspend/.resume callbacks does not work, as the order of those
callbacks amongst various devices in the camera pipeline like the sensor,
FPD serdes, CSI bridge etc. is impossible to enforce, even with
device links. For example, the Cadence CSI bridge is a child device of
this device, thus we cannot create a device link with the CSI bridge as
a provider and this device as consumer. This can lead to situations
where all the dependencies for the bridge have not yet resumed when we
request the subdev to start streaming again through the .resume callback
defined in this device.

Instead here we register a notifier callback with the PM framework
which is triggered when the system is fully functional. At this point we
can cleanly stop or start the streams, because we know all other devices
and their dependencies are functional. A downside of this approach is
that the userspace is also alive (not frozen yet, or just thawed), so
the suspend notifier might complete before the userspace has completed
all ioctls, like QBUF/DQBUF/STREAMON/STREAMOFF.

Don't call vivid_update_format_cap() when switching to/from reduced fps
for HDMI inputs: that will also reset the format, which is overkill for
this.

Make a new vivid_update_reduced_fps() function that just updates the
dev->timeperframe_vid_cap.

Subject: [PATCH 1268/5214] media: vivid: check for vb2_is_busy() when toggling
 caps

The vivid_update_format_cap/out() functions must only be called if the
capture/output queue are not busy. But for the controls that select
the CROP/COMPOSE/SCALE capability that is not checked.

Only when streaming starts will they be set to 'grabbed' and it is
impossible to change the control, but between REQBUFS and STREAMON you
are still allowed to set these controls. Since vivid_update_format_cap/out
will change the format, this can cause unexpected results.

Besides adding these checks, also add a WARN_ON in
vivid_update_format_cap/out() if the queue is busy.

I'm 90% certain that this is the cause of this syzbot bug:

https://syzkaller.appspot.com/bug?extid=dac8f5eaa46837e97b89

But since we never have reproducers, it is hard to be certain. In any case,
these checks are needed regardless.

Subject: [PATCH 1269/5214] clk: microchip: mpfs-ccc: fix peripheral driver
 registration failures after oob fix

Commit 2f7ae8ab6aa73 ("clk: microchip: mpfs-ccc: fix out of bounds
access during output registration") fixed the out of bounds access, but
it did so by packing sparse indices into a linear space. When
peripheral drivers request clocks, they obviously don't care for this
compression and use the sparse indices, and therefore try to request the
wrong clocks or clocks that don't exist.

The most straightforward fix here seems to stop being clever with the
packing and just overallocate the array.

Subject: [PATCH 1270/5214] perf riscv: Add SDT argument parsing for RISC-V

Implement __perf_sdt_arg_parse_op_riscv() to convert RISC-V GCC-generated
SDT probe operands into uprobe-compatible format, and register it in the
perf_sdt_arg_parse_op() dispatcher for EM_RISCV.

RISC-V GCC uses the 'nor' constraint for SDT arguments, producing operands
in the following formats:

  Format       Example      Uprobe format
  -----------  -----------  -------------
  register     a0           %a0
  memory (+)   8(a0)        +8(%a0)
  memory (-)   -20(s0)      -20(%s0)
  constant     99           (skip, not supported by uprobe)

Key differences from other architectures:
 - Register names use ABI aliases (a0-a7, t0-t6, s0-s11, sp, ra, etc.)
   without any '%' prefix, unlike x86 (%rax) or arm64 (x0).
 - Memory operands use OFFSET(REG) syntax where OFFSET may be negative,
   unlike arm64's [sp, NUM] or powerpc's NUM(%rREG).

Two regexes are used:
 - SDT_OP_REGEX1: matches RISC-V ABI register names saved in pt_regs
 - SDT_OP_REGEX2: matches [-]NUM(REG) memory operands

Subject: [PATCH 1271/5214] perf clang-format: Add a perf clang-format that
 overrides some kernel behaviors

In particular, header file ordering is an issue in the tools/perf
directory given the larger number of depended upon libraries.

The order of header file includes was proposed in:

  https://lore.kernel.org/linux-perf-users/CAP-5=fUitzKwJONTngiW17XkS7kVr2cDS4cDL_HccJKcnR2EgQ@mail.gmail.com/

Sorting headers is desirable to avoid issues like duplicate includes.

Subject: [PATCH 1272/5214] perf build-id: Fix off-by-one bug when printing
 kernel/module build-id

When changing sprintf functions to snprintf, one byte got lost. Since
snprintf ones do not handle the '\0' terminating character, the number
of printed characters is 40, while sizeof(sbuild_id) is 41, including
the terminating '\0' character.

This makes the later check fail so that nothing is printed.

Fix that.

Before:

    [Michael@Carbon ~]$ perf buildid-list -k
    [Michael@Carbon ~]$

After:

    [Michael@Carbon ~]$ perf buildid-list -k
    a527806324d543c4bc3ff2f9c9519d494fed5f68
    [Michael@Carbon ~]$

Subject: [PATCH 1273/5214] perf event: Fix size of synthesized sample with
 branch stacks

Synthesizing branch stacks for Intel-PT highlighted an issue where
PERF_SAMPLE_BRANCH_HW_INDEX was assumed to always be set in the
perf_event_attr branch_sample_type. This caused an incorrect size
calculation.

Fix the writing of the nr and hw_idx values during sample event
synthesis by passing the branch_sample_type into the sample size
and synthesis functions. Also update hardware tracers (Intel PT,
ARM SPE, CS-ETM) to retrieve and pass their branch_sample_type
dynamically to prevent payload misalignment.

Fixes: d3f85437ad6a5511 ("perf evsel: Support PERF_SAMPLE_BRANCH_HW_INDEX")

Subject: [PATCH 1274/5214] perf inject: Fix itrace branch stack synthesis

When using "perf inject --itrace=L" to synthesize branch stacks from
AUX data, several issues caused failures with the generated file:

1. The synthesized samples were delivered without the
   PERF_SAMPLE_BRANCH_STACK flag if it was not in the original event's
   sample_type. Fixed by using sample_type | evsel->synth_sample_type
   in intel_pt_do_synth_pebs_sample.

2. Modifying evsel->core.attr.sample_type early in __cmd_inject caused
   parse failures for subsequent records in the input file. Fixed by
   moving this modification to just before writing the header.

3. perf_event__repipe_sample was narrowed to only synthesize samples
   when branch stack injection was requested, and restored the use of
   perf_inject__cut_auxtrace_sample as a fallback to preserve
   functionality.

4. Potential Heap Overflow in perf_event__repipe_sample: Addressed by
   adding a check that prints an error and returns -EFAULT if the
   calculated event size exceeds PERF_SAMPLE_MAX_SIZE.

5. Header vs Payload Mismatch in __cmd_inject: Addressed by narrowing
   the condition so that HEADER_BRANCH_STACK is only set in the file
   header if add_last_branch was true.

6. NULL Pointer Dereference in intel-pt.c: When branch stack injection
   is requested (add_last_branch is true) but last_branch is false
   (e.g., perf inject --itrace=L), ptq->last_branch was not allocated.
   However, PEBS branch stack synthesis (via synth_sample_type) still
   forced LBR handling in do_synth_pebs_sample(), dereferencing the
   NULL ptq->last_branch pointer. Guarding the dereference is not
   sufficient because downstream sample size calculation and synthesis
   strictly require a non-NULL branch_stack when the bit is set.
   Fixed by ensuring ptq->last_branch is allocated in
   intel_pt_alloc_queue() when add_last_branch is requested.

7. Modifying event attributes in perf_event__repipe_attr in-place caused
   SIGSEGV on read-only mmap buffers in file mode and downstream parser
   breakage in pipe mode. Fixed by processing the unmodified attribute
   first, returning immediately in non-pipe mode, and correctly
   synthesizing a new attribute event for pipe output using
   perf_event__synthesize_attr. Also:
   - Added a size validation check and integer underflow protection when
     parsing n_ids.
   - Prevented Trailing ID memory corruption by zero-initializing the
     local attr copy and safely copying using min_t(size_t, sizeof(attr),
     event->attr.attr.size).
   - Resolved ID array parsing mismatch downstream by expanding attr.size
     to sizeof(struct perf_event_attr) before synthesis to guarantee
     perfect header/attribute size alignment.

8. Potential dangling pointer vulnerability in perf_event__repipe_sample:
   Addressed by restoring the original sample->branch_stack pointer
   before returning, including on early error return paths.

9. Off-by-one error in sample size check in perf_event__repipe_sample:
   Fixed by checking if sz >= PERF_SAMPLE_MAX_SIZE instead of >.

10. Unadvertised size field left in payload by cut_auxtrace_sample:
    Addressed by excluding the 8-byte size field from the copied
    payload to correctly match the cleared PERF_SAMPLE_AUX bit. Cut
    the AUX sample payload even if size is 0.

11. Inaccurate sample size calculation and uninitialized memory leaks in
    convert_sample_callchain: Fixed by replacing manual arithmetic with
    perf_event__sample_event_size and adding a bounds check against
    PERF_SAMPLE_MAX_SIZE.

12. Omission of branch_sample_type in file headers: Addressed by
    expanding older, smaller attributes to PERF_ATTR_SIZE_VER2 in
    __cmd_inject to ensure branch_sample_type is not silently omitted.

Subject: [PATCH 1275/5214] perf tool: Remove evsel from tool APIs that pass
 the sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from tool-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

From 1c8b07788618a30bd0bb6d83aeb39d07b8d57bbf Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Wed, 20 May 2026 12:05:08 -0700
Subject: [PATCH 1276/5214] perf kvm: Don't pass evsel with sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from kvm-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

From fd7dd303c430bf230b2192eb06696a7361f19850 Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Wed, 20 May 2026 12:05:09 -0700
Subject: [PATCH 1277/5214] perf evsel: Refactor evsel tracepoint sample
 accessors perf_sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The evsel argument to evsel__intval, evsel__rawptr, and similar
functions, is unnecessary as it can be read from the sample. Remove
the evsel and rename the function to match that the data is coming
from the sample.

Subject: [PATCH 1280/5214] perf lock: Only pass sample to handlers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The evsel is within the sample and so only the sample needs to be
passed. Remove the parameter and fix call site.

Subject: [PATCH 1281/5214] perf hist: Remove evsel parameter from inc samples
 functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from hist-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

Subject: [PATCH 1282/5214] perf db-export: Remove evsel from struct
 export_sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from db-export-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

 computing from sample->id
MIME-Version: 1.0

In count_lost_samples_events try to avoid searching for the evsel for
the sample, just use the variable within the sample.

Subject: [PATCH 1285/5214] perf annotate: Don't pass evsel to add_sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from annotate-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

From: Ian Rogers <irogers@google.com>
Date: Wed, 20 May 2026 12:05:19 -0700
Subject: [PATCH 1287/5214] perf kmem: Don't pass evsel with sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from kmem-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

From 1ac10645bb29265048b3e982d0de6b06ccb4cf2d Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Wed, 20 May 2026 12:05:21 -0700
Subject: [PATCH 1289/5214] perf sched: Don't pass evsel with sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from sched-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

From: Ian Rogers <irogers@google.com>
Date: Wed, 20 May 2026 12:05:22 -0700
Subject: [PATCH 1290/5214] perf timechart: Don't pass evsel with sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from timechart-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

Subject: [PATCH 1292/5214] perf evlist: Try to avoid computing evsel from
 sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from evlist-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

Subject: [PATCH 1294/5214] perf s390-sample-raw: Don't pass evsel or its PMU
 with sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.

Remove the redundant evsel parameter from s390-sample-raw-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

Since the trace lock handler callbacks and definitions do not change at runtime,
declare them const to enforce read-only memory placement and improve safety.

 callchain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Avoid a potential segmentation fault if a parsed sample unexpectedly lacks a
valid callchain pointer.

Add a check for a NULL sample->callchain pointer in get_callstack(). If the
callchain is missing, return NULL to safely skip the event and log a debug
warning rather than causing a tool segfault.

Subject: [PATCH 1298/5214] perf timechart: Fix memory leaks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resolve a major execution-time leak of backtrace strings in the timechart tool.

- Modify cat_backtrace() to return dynamically allocated memory via
  open_memstream(), transferring ownership to the caller.
- Free the returned backtrace string inside process_sample_event() immediately
  after invoking the tracepoint handler.
- In handlers like pid_put_sample() and sched_wakeup(), make a separate copy of
  the backtrace using strdup() if it needs to be persisted in the sample struct,
  preventing lifetime issues and double-free vulnerabilities.

Subject: [PATCH 1299/5214] perf kmem: Fix memory leaks on error path and when
 skipping
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix memory leaks on the error paths and skipped sample handling paths
in the perf kmem tool.

Ensure that all allocated GFP flags and thread references are properly freed and
released via thread__put() when skipping samples or encountering parsing failures,
preventing long-term memory usage leaks during large trace analyses.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add robust boundary checks when synthesizing mmap2 and build_id events to
ensure that filename fields do not overflow the fixed-size stack allocations or the
synthesized event structures.

Verify that the filename fits safely within the allocated boundaries of the
mmap2 event structure, and prevent potential heap/stack overflow corruptions
from excessively long or corrupted kernel filenames.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sanitize order and migrate_type values from tracepoint payloads before using
them as array indexes.

When processing page_alloc_event and page_free_event, verify that 'order' is less
than MAX_PAGE_ORDER and 'migrate_type' is less than MAX_MIGRATE_TYPES. This
guarantees that indexing into order_stats[MAX_PAGE_ORDER][MAX_MIGRATE_TYPES] remains
strictly within bounds, avoiding out-of-bound heap or static segment accesses.

Ensure CPU indexes parsed from sched switch and runtime events fit within the
MAX_CPUS limit to prevent out-of-bounds indexing.

Add explicit bounds checks for sample->cpu against MAX_CPUS inside
process_sched_switch_event, process_sched_runtime_event, and
timehist_sched_change_event. This prevents indexing beyond the boundaries
of the sched->curr_pid tracking array, avoiding potential memory corruption or
undefined behavior.

Prevent out-of-bounds writes/reads in CPU state tracking arrays by enforcing
strict MAX_CPUS bounds checks in timechart's tracepoint handlers.

Ensure that cpu_id retrieved from idle/frequency and sched tracepoints is less
than MAX_CPUS before indexing into cpus_cstate_state, cpus_cstate_start_times,
and similar tracking arrays. Also, fix an off-by-one error in the CPU iteration
loop inside end_sample_processing() by changing the loop condition from
'cpu <= tchart->numcpus' to 'cpu < tchart->numcpus'.

Subject: [PATCH 1304/5214] perf evsel: Add bounds checking to trace point raw
 data accessors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prevent out-of-bounds memory reads when parsing corrupted or maliciously crafted
perf.data files by introducing robust bounds validation to raw data accessors.

- Add a helper out_of_bounds() to check if field offsets and sizes exceed the
  sample's raw_size boundary, preventing heap read overflows.
- In perf_sample__rawptr(), properly resolve newer relative dynamic tracepoint
  fields (__rel_loc) by checking the boundaries before and after reading the
  dynamic field descriptor.
- Byte-swap dynamic field offsets and sizes dynamically when endianness varies,
  ensuring cross-endian parsing is robust.

Subject: [PATCH 1305/5214] perf sched stats: Fix SIGCHLD vs pause() race in
 schedstat_record()

If the profiled workload exits very quickly, SIGCHLD can be delivered
and consumed by the empty signal handler before the process enters
pause(), causing an indefinite hang.

Fix this with a simpler approach:

 - The signal handler now sets a 'volatile sig_atomic_t done' flag.
   Reset 'done' before registering signal handlers so that an early
   signal during setup is not discarded by a later reset.

 - Replace pause() with a loop that checks 'done' and uses
   waitpid(WNOHANG) to detect child exit without blocking.  This
   handles both workload mode (child exits) and system-wide mode
   (user sends SIGINT/SIGTERM).  Using WNOHANG avoids the SA_RESTART
   problem where a blocking waitpid() would auto-restart and ignore
   the done flag if the child doesn't exit on signal.

Subject: [PATCH 1308/5214] perf trace beauty: Make beauty generated C code
 standalone .o files

Previously, builtin-trace.c directly included 15 embedded C files
(e.g. trace/beauty/mmap.c and fsconfig_arrays.c), which in turn depend
on dozens of generated beauty script arrays. To satisfy these embedded
inclusions, the global Makefile.perf would define all the generator
variables/rules and include them in the prepare umbrella target, choking
parallel build startup.

Furthermore, tools/perf/util/syscalltbl.c included its own generated mapper,
and util/env.c conditionally included arch_errno_names.c inline, splitting
consumers across directories and preventing clean Make encapsulation.

Refactor the framework to achieve better encapsulation:
1. Move util/syscalltbl.[ch] into trace/beauty/ to co-locate with all
   generated code consumers.
2. Create fsconfig.c and flatten embedded beauty .c files to compile as
   independent standalone objects via trace/beauty/Build, exporting their
   formatting functions via beauty.h and env.h. Switch arch_errno_names.o
   and syscalltbl.o assignments directly to perf-util-y and add an
   unconditional top-level recursive kbuild hook (perf-util-y += trace/beauty/)
   to compile them into libperf-util.a, resolving remote linkage for util/env.c,
   util/bpf-trace-summary.c, and standalone python extensions.
3. Bridge private opaque references (struct trace) securely via accessors
   trace__show_zeros() and trace__host(), avoiding header entanglements.
4. Consolidate all generator variables, script paths, and array generation
   rules entirely out of Makefile.perf and place them directly inside the
   exact local Build files where their output objects are compiled
   (trace/beauty/Build and trace/beauty/tracepoints/Build), binding
   prerequisites locally. Use  directly inside
   generator recipes to guarantee dynamic directory creation before script
   redirection, and append  across all rules to print
   clean, standardized GEN ... file.c output during compilation.
5. Clean up clean target to recursively remove the generated directory
   instead of relying on dozens of individual variables.

This unchokes the "prepare" target parallel barrier, allows make to evaluate
generation scripts purely locally where consumed, and flattens the tracepoint
formatting architecture.

Testing a parallel build (make -j28 all from scratch) shows improvements:
  Before:
    real    0m28.689s
    user    2m38.490s
    sys     0m30.148s

  After:
    real    0m27.642s
    user    2m32.356s
    sys     0m26.683s

So reclaiming ~9.6 seconds of raw CPU time and over 1 full second off
overall real-world build latency, by overlapping sub-make startup and
avoiding top-level double-parsing overhead.

Subject: [PATCH 1309/5214] perf build: Decouple pmu-events from prepare
 umbrella target

Currently, the $(LIBPMU_EVENTS_IN) sub-make depends on the massive
"prepare" umbrella target. Because "prepare" depends on external
libraries (libapi, libperf, etc.) as well as dozens of generated
headers, make completely serializes the launch of the pmu-events
sub-make behind some of those unrelated prerequisites.

Since pmu-events is a large compilation unit, unblock its startup by
binding it directly to only $(LIBPERF) instead of prepare. This allows
background python generation scripts to overlap simultaneously with
the rest of the build.

Testing a parallel build (make -j28 clean all) shows improvements:
  Before:
    real    0m27.642s
    user    2m32.356s
    sys     0m26.683s

  After:
    real    0m22.254s
    user    2m32.810s
    sys     0m24.646s

This reclaims over 5 full seconds of build latency (~19.5% overall
reduction) by elevating average CPU concurrency from ~5.5 active cores
up to ~8 active cores.

Subject: [PATCH 1311/5214] perf build: Move BPF skeleton generation out of
 Makefile.perf

Currently, the top-level Makefile.perf defines a massive global bpf-skel
umbrella target that pre-compiles all 12+ BPF skeletons (%.skel.h) upfront
before launching sub-makes. This forces unrelated sub-makes to serialize
behind bpftool and clang BPF target evaluations, causing parallel build
bottlenecks.

Furthermore, bench_uprobe.bpf.c lived inside util/bpf_skel/, breaking
conceptual directory encapsulation since it is consumed purely by
bench/uprobe.c.

Refactor the BPF skeletons to better achieve directory isolation:
1. Move tools/perf/util/bpf_skel/bench_uprobe.bpf.c directly into
   tools/perf/bench/bpf_skel/.
2. Extract the skeleton generation infrastructure out of Makefile.perf into
   a shared inclusion file tools/perf/bpf_skel.mak.
3. Include bpf_skel.mak locally inside tools/perf/util/Build and
   tools/perf/bench/Build and bind precise local prerequisites.
4. Safely synchronize the shared bpftool bootstrap and vmlinux.h targets
   via the conditional prepare: umbrella to avoid parallel sub-make races,
   while evaluating the actual skeletons completely locally on demand. A
   later patch will move these targets into bpf_skel.mak.
5. Export CLANG from the global Makefile to ensure accurate tool
   propagation.
6. Clean up Makefile.perf by stripping the global bpf-skel umbrella target
   and its SKELETONS list.

While removing code from Makefile.perf generally helps build
performance, the impact here is minimal. The main motivation for the
change is to better encapsulate things in the build and simplify
Makefile.perf that has around 50 lines removed.

prepare target in Makefile.perf. This unnecessarily blocks the massive
parallel C compilation of libraries (perf-util, perf-ui, pmu-events) during
the initial startup phase.

Move all bpftool and vmlinux.h generation rules down into
tools/perf/bpf_skel.mak to encapsulate BPF tooling completely within the
skeleton framework. Remove them entirely from prepare to unblock immediate
parallel build execution.

To prevent parallel sub-makes (perf-util and perf-bench) from racing to
build shared prerequisites concurrently, while maintaining strict directory
encapsulation without top-level inclusions, serialize bench after the util
static archive finishes using an order-only prerequisite:
  $(LIBPERF_BENCH_IN): FORCE prepare | $(LIBPERF_UTIL)

Subject: [PATCH 1313/5214] perf build: Pre-generate BPF skeleton tooling
 during umbrella prepare phase

Currently, BPF skeleton generation rules (bpf_skel.mak) are evaluated as
part of util/Build. However, because LIBPERF_UTIL_IN explicitly depends
on the top-level static libbpf archive, Make completely blocked the
execution of bpftool bootstrap and skeleton generation until libbpf
finished compiling midway through the build.

Since bpftool bootstrap compiles its own independent copy of libbpf.a, it
does not depend on the top-level libbpf target.

Decouple early skeleton tooling generation by attaching bpf-skel-prepare
to the umbrella prepare target, exporting CONFIG_PERF_BPF_SKEL to ensure
accurate feature propagation. This allows Make to compile bpftool and
dump vmlinux.h in the background at build startup, eliminating the initial
sub-make startup bottleneck before BPF object compilation while keeping
100% of tooling rules perfectly encapsulated in bpf_skel.mak. Provide an
empty fallback target to ensure builds succeed when BPF skeletons are
disabled.

Subject: [PATCH 1315/5214] perf build: Remove redundant libbpf feature check
 for static builds

By default, the perf tool compiles and statically links against its own
internal copy of libbpf (tools/lib/bpf/libbpf.a), setting LIBBPF_STATIC=1.

Despite this static linkage, Makefile.config unconditionally executed
$(call feature_check,libbpf), which forced a synchronous sub-make fork
during AST parsing to detect dynamic system libbpf libraries.

As noted in the internal Makefile comments, this check was executed purely
so that running `make VF=1` would display the detection status of system
libbpf. During standard builds without LIBBPF_DYNAMIC=1, the detection
result was entirely ignored.

Wrap the libbpf feature check inside LIBBPF_DYNAMIC=1 so Make avoids the
redundant sub-make fork overhead during standard static builds.

Subject: [PATCH 1316/5214] perf pmu-events: Split big_c_string storage into
 standalone compilation unit

Currently, jevents.py emits both the massive 2.8 MB big_c_string literal
and tens of thousands of compact_pmu_event struct arrays into a single
pmu-events.c compilation unit. Compiling this giant file takes ~2.2 seconds
on a single CPU core during Kbuild startup.

Refactor jevents.py to emit big_c_string into a dedicated
pmu-events-string.c compilation unit. This allows Kbuild to compile
pmu-events.o and pmu-events-string.o simultaneously in parallel across
two separate CPU cores, preserving 100% string deduplication and zero
dynamic ELF relocations while cutting C compilation latency in half.

Add pmu-events-string.c to tools/perf/.gitignore to ensure in-tree Kbuild
runs do not leave untracked generated files in the working directory.

To guarantee 100% backward compatibility with GNU Make 4.0+ (avoiding the
Make 4.3+ grouped target &: syntax which causes older Make versions like
4.2.1 to spawn multiple concurrent jevents.py processes during parallel
builds), implement a robust dependency chaining pattern:
  $(PMU_EVENTS_C): $(JEVENTS_DEPS)
  $(PMU_EVENTS_STRING_C): $(PMU_EVENTS_C)
          @:
This ensures jevents.py is invoked exactly once. If jevents.py aborts
early, Make's .DELETE_ON_ERROR: purges pmu-events.c, guaranteeing that
subsequent Make invocations correctly re-execute the script and overwrite
pmu-events-string.c. In jevents.py, explicitly close output_file first
and output_string_file second at the tail of main() to guarantee that
pmu-events-string.c receives a filesystem timestamp greater than or equal
to pmu-events.c, completely avoiding redundant incremental rebuilds.

Subject: [PATCH 1317/5214] perf pmu-events: Convert recursive shell
 assignments and macros to Make built-ins

In pmu-events/Build, ZENS, ARMS, and INTELS were assigned using recursive
assignment (=), and model_name/vendor_name were evaluated using shell
macros (echo ... | sed ...).

Because these variables were expanded inside the COPY_RULE dependency
evaluation loop across hundreds of PMU JSON files and inside every metric
generation recipe, Kbuild continuously re-executed 'ls', 'grep', and 'sed'
shell forks thousands of times during AST parsing and execution.

Convert ZENS, ARMS, and INTELS to simply expanded variables (:=) and
replace model_name/vendor_name with pure GNU Make string functions. This
guarantees Make executes directory probing shell forks exactly once when
the Build file is parsed and evaluates path macros purely in memory,
completely eliminating over 7,800 redundant sub-processes during build
startup.

Subject: [PATCH 1319/5214] perf tests: Add test for uncore event sorting

Add a test for uncore event sorting matching multiple PMUs.

Uncore PMUs may have a common prefix, like the PMUs
uncore_imc_free_running_0 and uncore_imc_free_running_1 have a prefix of
uncore_imc_free_running.

Parsing an event group like "{data_read,data_write}" for those PMUs
should result with two groups:

  "{uncore_imc_free_running_0/data_read/,uncore_imc_free_running_0/data_write/},
   {uncore_imc_free_running_1/data_read/,uncore_imc_free_running_1/data_write/}"

which means the evsels need resorting as when initially parsed the
evsels are ordered with mixed PMUs:

  "{uncore_imc_free_running_0/data_read/,uncore_imc_free_running_1/data_read/,
  uncore_imc_free_running_0/data_write/,uncore_imc_free_running_1/data_write/}".

Subject: [PATCH 1320/5214] perf arch x86 tests: Add test for topdown event
 sorting

Add a test to capture the comment in tools/perf/arch/x86/util/evlist.c.

Test that slots and topdown-retiring get appropriately sorted with
respect to instructions when they're all specified together.

When the PMU requires topdown event grouping (indicated by the pressence
of the slots event) metric events should be after slots, which should be
the group leader.

Add a related test that when the slots event isn't given it is injected
into the appropriate group.

Subject: [PATCH 1321/5214] perf build: Prefix SCRIPTS with output directory to
 fix continuous rebuilds

In Makefile.perf, ALL_PROGRAMS includes SCRIPTS (perf-archive,
perf-iostat). However, unlike PROGRAMS and DLFILTERS, SCRIPTS was not
prefixed with $(OUTPUT).

During out-of-tree builds (or when O= is specified), Make checked for the
unprefixed target 'tools/perf/perf-archive'. Since the actual script was
installed into $(OUTPUT)perf-archive, Make concluded the target was
missing and continuously re-executed the script installation rule on every
single incremental build.

Prefix SCRIPTS with $(OUTPUT) and update the static pattern rule to ensure
Kbuild correctly tracks generated script prerequisites during incremental
builds.

Subject: [PATCH 1325/5214] media: rkisp1: Add support for CAC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The CAC block implements chromatic aberration correction. Expose it to
userspace using the extensible parameters format. This was tested on the
i.MX8MP platform, but based on available documentation it is also present
in the RK3399 variant (V10). Thus presumably also in later versions,
so no feature flag is introduced.

+ *
+ *   (((d << 4) >> ns) * nf) >> 5
+ *
+ * where `d` is the distance, `ns` and `nf` are the normalization parameters:

+ * @x_nf: horizontal normalization scale parameter (5-bit unsigned integer; [0,31])
+ * @x_ns: horizontal normalization shift parameter (4-bit unsigned integer; [0,15])
+ *
+ * @y_nf: vertical normalization scale parameter (5-bit unsigned integer; [0,31])
+ * @y_ns: vertical normalization shift parameter (4-bit unsigned integer; [0,15])

+ * is larger than 255. If the pixels have square shape, the two sets of parameters

+ *
+ * where `c` is the set of coefficients for the given color, and `r` is distance:

+ * @blue: blue coefficients (5.4 two's complement; [-16,15.9375])

The problem is that mxc_isi_remove() calls mxc_isi_crossbar_cleanup()
before mxc_isi_v4l2_cleanup(). The crossbar cleanup frees the media
entity pads, but the subsequent v4l2 cleanup still tries to remove
media links that reference those pads.

Fix this by calling mxc_isi_v4l2_cleanup() before
mxc_isi_crossbar_cleanup() to ensure all media entities are properly
unregistered while the pads are still valid.

This causes a memory leak on every rmmod, reported by kmemleak:

Subject: [PATCH 1328/5214] media: nxp: imx8-isi: Fix missing
 v4l2_subdev_cleanup() in pipe init error path

After v4l2_subdev_init_finalize() succeeds in mxc_isi_pipe_init(), if
platform_get_irq() or devm_request_irq() fails, the error path jumps to
a label that only calls media_entity_cleanup() and mutex_destroy(),
missing the v4l2_subdev_cleanup() call needed to free the subdev active
state allocated by v4l2_subdev_init_finalize().

Add an error_subdev label that calls v4l2_subdev_cleanup() before
falling through to the existing error cleanup.

Subject: [PATCH 1330/5214] media: nxp: imx8-isi: Prioritize pending buffers
 over discard buffers

The number of times to use the discard buffer is determined by the
out_pending list size:

  discard = list_empty(&video->out_pending) ? 2
            : list_is_singular(&video->out_pending) ? 1
	    : 0;

In the current buffer selection logic, when both discard and pending
buffers are available, the driver fills hardware slots with discard
buffers first which results in an unnecessary frame drop even though
a user buffer was queued and ready.

Change the buffer selection logic to use pending buffers first (up to
the number available), and only use discard buffers to fill remaining
slots when insufficient pending buffers are queued.

This improves behavior by:
- Reducing discarded frames at stream start when user buffers are ready
- Decreasing latency in delivering captured frames to user-space
- Ensuring user buffers are utilized as soon as they are queued
- Improving overall buffer utilization efficiency

Subject: [PATCH 1334/5214] KVM: arm64: nv: Don't save/restore FP register
 during a nested ERET or exception

When switching between L1 and L2, we save the old state using
kvm_arch_vcpu_put(), mutate the state in memory, then load the new
state using kvm_arch_vcpu_load(). Any live FPSIMD/SVE state is saved
and unbound, such that it can be lazily restored on a subsequent trap.

The FPSIMD/SVE state is shared by exception levels, and only a handful
of related control registers need to be changed when transitioning
between L1 and L2. The save/restore of the common state is needless
overhead, especially as trapping becomes exponentially more expensive
with nesting.

Avoid this overhead by leaving the common FPSIMD/SVE state live on the
CPU, and only switching the state that is distinct for L1 and L2:

- the trap controls: the effective values are recomputed on each entry
  into the guest to take the EL into account and merge the L0 and L1
  configuration if in a nested context, or directly use the L0 configuration
  in non-nested context (see __activate_traps()).

- the VL settings: the effective values are are also recomputed on each
  entry into the guest (see fpsimd_lazy_switch_to_guest()).

Since we appear to cover all bases, use the vcpu flags indicating the
handling of a nested ERET or exception delivery to avoid the whole FP
save/restore shenanigans. SME will have to be similarly dealt with when
it eventually gets supported.

For an EL1 L3 guest where L1 and L2 have this optimisation, this
results in at least a 10% wall clock reduction when running an I/O
heavy workload, generating a high rate of nested exceptions.

Subject: [PATCH 1335/5214] KVM: arm64: timer: Repaint
 kvm_timer_{should,irq_can}_fire() to kvm_timer_{pending,enabled}()

kvm_timer_should_fire() seems to date back to a time where the author
of the timer code didn't seem to have made the word "pending" part of
their vocabulary.

Having since slightly improved on that front, let's rename this predicate
to kvm_timer_pending(), which clearly indicates whether the timer
interrupt is pending or not.

Similarly, kvm_timer_irq_can_fire() is renamed to kvm_timer_enabled().

Subject: [PATCH 1336/5214] KVM: arm64: Simplify userspace notification of
 interrupt state

The userspace notification of interrupts is has a few problems:

- it is utterly pointless

- it is annoyingly split between detecting the need for notification
  and the population of the interrupts in the run structure

We can't do anything about the former (yet), but the latter can be
addressed. If we detect that we must notify userspace, we know that
we are going to exit, as we populate the exit status. Which means
we can also populate the interrupt state at this stage and be done
with it.

This simplifies the structure of the code.

Subject: [PATCH 1337/5214] KVM: arm64: timer: Kill the per-timer irq level
 cache

The timer code makes use of a per-timer irq level cache, which
looks like a very minor optimisation to avoid taking a lock upon
updating the GIC view of the interrupt when it is unchanged from
the previous state.

This is coming in the way of more important correctness issues,
so get rid of the cache, which simplifies a couple of minor things.

Subject: [PATCH 1339/5214] KVM: arm64: vgic-v2: Force vgic init on injection
 outside the run loop

Make sure that any attempt to inject an interrupt from userspace
or an irqfd results in the GICv2 lazy init to take place.

This is not currently necessary as the init is also performed on
*any* interrupt injection. But as we're about to remove that,
let's introduce it here.

Subject: [PATCH 1340/5214] KVM: arm64: vgic-v2: Don't init the vgic on
 in-kernel interrupt injection

We now have the lazy init on three paths:

- on first run of a vcpu
- on first injection of an interrupt from userspace and irqfd
- on first injection of an interrupt from kernel space as
  part of the device emulation (timers, PMU, vgic MI)

Given that we recompute the state of each in-kernel interrupt
every time we are about to enter the guest, we can drop the lazy
init from the kernel injection path.

This solves a bunch of issues related to vgic_lazy_init() being called
in non-preemptible context, such as vcpu reset.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The vsp1_du_setup_lif() function is used to configure and enable a
pipeline, as well as disable it, depending on the cfg argument being a
valid pointer or NULL. This creates a confusing API. Improve it by
splitting the function in two, a vsp1_du_enable() function to configure
a pipeline, and a vsp1_du_disable() function to disaple it.

Keep vsp1_du_setup_lif() as an inline wrapper for existing callers in
the DRM subsystem, to simplify merging. The callers will be updated
separately and the old API will then be removed.

Subject: [PATCH 1345/5214] media: renesas: vsp1: Use mutex guards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace manual mutex locking and unlocking with guards. This simplifies
error paths and reduces the amount of code. Limit the changes to
locations where the guard covers until the end of the function to ease
review. Scoped guards will be introduced separately.

Subject: [PATCH 1346/5214] media: renesas: vsp1: Use mutex scoped guards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace remaining manual mutex locking and unlocking with scoped
guards. This simplifies error paths and reduces the amount of code.

Subject: [PATCH 1347/5214] media: renesas: vsp1: Use spinlock guards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace manual spinlock locking and unlocking with guards. This
simplifies error paths and reduces the amount of code. Limit the changes
to locations where the guard covers until the end of the function to
ease review. Scoped guards will be introduced separately.

Subject: [PATCH 1351/5214] comedi: Consistently define pci_device_ids using
 named initializers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .driver_data member of the various struct pci_device_id arrays were
initialized by list expressions. This isn't easily readable if you're
not into PCI. Using named initializers is more explicit and thus easier
to parse. Also skip explicit assignments of 0 (which the compiler takes
care of).

The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.

This change doesn't introduce changes to the compiled pci_device_id
arrays. Tested on x86 and arm64.

Subject: [PATCH 1352/5214] staging: octeon: ethernet-mem: replace pr_warn with
 dev_warn in free functions

Add struct platform_device parameter to cvm_oct_free_hw_skbuff,
cvm_oct_free_hw_memory and cvm_oct_mem_empty_fpa. Replace pr_warn
calls with dev_warn, using &pdev->dev for device-aware logging.

Subject: [PATCH 1353/5214] staging: octeon: ethernet: replace pr_err and
 pr_info with dev_err and netdev_err

Replace pr_err() and pr_info() calls in cvm_oct_probe() with
dev_err(), netdev_err(), and netdev_info() to include device
information in log messages. Use dev_err() where no net_device
is available (allocation failures), and netdev_err()/netdev_info()
where a net_device exists.

Subject: [PATCH 1354/5214] staging: octeon: replace pr_warn with dev_warn in
 fill and rx paths

Add struct platform_device parameter to cvm_oct_fill_hw_memory,
cvm_oct_mem_fill_fpa, cvm_oct_rx_refill_pool and
cvm_oct_rx_initialize to support device-aware logging. Replace
pr_warn with dev_warn using &pdev->dev.
To avoid passing these parameters through global state, introduce
struct octeon_ethernet_platform to hold per-device state including
the rx_refill_work and the oct_rx_group array. This ensures all
receive group state and workers are correctly associated with the
platform device.
Define struct oct_rx_group and struct octeon_ethernet_platform in
octeon-ethernet.h so they are shared across compilation units.

Subject: [PATCH 1356/5214] staging: rtl8723bs: remove unnecessary blank lines
 in rtw_mlme_ext.c

Remove unnecessary blank lines around braces {} to improve readability.

This fixes the following checkpatch.pl checks in rtw_mlme_ext.c:
- CHECK: Blank lines aren't necessary after an open brace '{'
- CHECK: Blank lines aren't necessary before a close brace '}'

Subject: [PATCH 1364/5214] staging: rtl8723bs: remove overwriting of current
 IMR settings

Originally, this code use to
	Step 1: Read a value from register
	Step 2: Add some bits to the value
	Step 3: Write the result back to the same register

The problem was that the bits in Step 2 were always zero and didn't
change the value, so I have removed that code. Now this function
just reads a value and writes the same value back. It is unnecessary
and can be removed.

Subject: [PATCH 1371/5214] media: dt-bindings: media: rockchip-rga: add
 rockchip,rk3588-rga3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a new compatible for the RGA3 (Raster Graphic Acceleration 3)
peripheral found on the RK3588 SoC. Also specify an iommu property,
as the RGA3 contains the generic rockchip iommu. While other versions
also have an iommu, it's usually specific to them.

The RK3588 contains one RGA2-Enhance core (also contained on the RK3399)
and two RGA3 cores. Both feature a similar functionality of scaling,
cropping and rotating of up to two input images into one output image.
Key differences of the RGA3 are:

- supports 10bit YUV output formats
- supports 8x8 tiles and FBCD as inputs and outputs
- supports BT2020 color space conversion
- max output resolution of (8192-64)x(8192-64)
- MMU can map up to 32G DDR RAM
- fully planar formats (3 planes) are not supported
- max scale up/down factor of 8 (RGA2 allows up to 16)

Subject: [PATCH 1372/5214] media: v4l2-common: sort RGB formats in
 v4l2_format_info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sort the RGB formats in v4l2_format_info to match the format definitions
in include/uapi/linux/videodev2.h . Also introduce the same sections to
partition the list of formats and align the format info in each section.

The alignment of the 1 or 2 bytes RGB formats contains an additional
space in preparation of adding the missing formats to the list, as for
V4L2_PIX_FMT_ARGB555X an additional space is necessary.

Subject: [PATCH 1373/5214] media: v4l2-common: add missing 1 and 2 byte RGB
 formats to v4l2_format_info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add all missing one and two byte RGB formats to v4l2_format_info. This
allows drivers to more consistently use v4l2_format_info, as it now
covers all currently defined RGB formats.

Subject: [PATCH 1374/5214] media: v4l2-common: add has_alpha to
 v4l2_format_info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a has_alpha value to the v4l2_format_info struct to indicate if the
format contains an alpha component. This information can currently not
be queried in a generic way, but might be useful for potential drivers
to properly setup alpha blending to copy or set the alpha value.
The implementation is based on the drm_format_info implementation.

Subject: [PATCH 1375/5214] media: v4l2-common: add v4l2_fill_pixfmt_mp_aligned
 helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a v4l2_fill_pixfmt_mp_aligned helper which allows the user to
specify a custom stride alignment in bytes. This is necessary for
hardware like the Rockchip RGA3, which requires the stride value to be
aligned to a 16 bytes boundary.

The code makes some assumptions about the v4l2 format to simplify the
calculation. They currently hold for all known v4l2 formats.

v4l2_format_plane_stride uses an unsigned int as argument type to avoid
the later multiplication from overflowing the u8 value. All other places
use u8, as no practical use cases for a larger alignment are known at
the moment.

Subject: [PATCH 1376/5214] media: rockchip: rga: fix too small buffer size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix the command buffer size being only a quarter of the actual size.
The RGA_CMDBUF_SIZE macro was potentially intended to specify the length
of the cmdbuf u32 array pointer. But as it's used to specify the size of
the allocation, which is counted in bytes. Therefore adjust the macro
size to bytes as it better matches the variable name and adjust it's
users accordingly.

As the command buffer is relatively small, it probably didn't caused
an issue due to being smaller than a single page.

Subject: [PATCH 1378/5214] media: rockchip: rga: use stride for offset
 calculation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use the stride instead of the width for the offset calculation. This
ensures that the bytesperline value doesn't need to match the width
value of the image.

Furthermore this patch removes the dependency on the uv_factor property
and instead reuses the v4l2_format_info to determine the correct
division factor.

Subject: [PATCH 1379/5214] media: rockchip: rga: remove redundant rga_frame
 variables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the redundant rga_frame variables width, height and color space.
The value of these variables is already contained in the pix member
of rga_frame. The code also keeps these values in sync. Therefore drop
them in favor of the existing pix member.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

Announce the capability to adjust the quantization and ycbcr_enc on the
capture side and check if the SET_CSC flag is set when the colorimetry
is changed. Furthermore copy the colorimetry from the output to the
capture side to fix the currently failing v4l2-compliance tests, which
expect exactly this behavior.

Subject: [PATCH 1381/5214] media: rockchip: rga: move hw specific parts to a
 dedicated struct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In preparation for the RGA3 unit, move RGA2 specific parts from rga.c
to rga-hw.c and create a struct to reference the RGA2 specific functions
and formats. This also allows to remove the rga-hw.h reference from the
include list of the rga driver.

Also document the command finish interrupt with a dedicated define.

Subject: [PATCH 1382/5214] media: rockchip: rga: avoid odd frame sizes for YUV
 formats
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Avoid odd frame sizes for YUV formats, as they may cause undefined
behavior. This is done in preparation for the RGA3, which hangs when the
output format is set to 129x129 pixel YUV420 SP (NV12).

This requirement is documented explicitly for the RGA3 in  section 5.6.3
of the RK3588 TRM Part 2. For the RGA2 the RK3588 TRM Part 2
(section 6.1.2) and RK3568 TRM Part 2 (section 14.2) only mentions the
x/y offsets and stride aligning requirements. But the vendor driver for
the RGA2 also contains checks for the width and height to be aligned to
2 bytes.

Subject: [PATCH 1384/5214] media: rockchip: rga: move cmdbuf to rga_ctx
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the command buffer to the rga_ctx struct in preparation to reuse
an already prepared command buffer. This allows to split the command
buffer setup in a further commit to setup a template for the command
buffer at streamon and only update the buffer addresses in device_run
and trigger the command stream. No sync point is added, as one command
buffer should only be used for one conversion at a time.

Subject: [PATCH 1385/5214] media: rockchip: rga: align stride to 4 bytes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add an alignment setting to rga_hw to set the desired stride alignment.
As the RGA2 register for the stride counts in word units, the code
already divides the bytesperline value by 4 when writing it into the
register. Therefore fix the alignment to a multiple of 4 to avoid
potential off by one errors due from the division.

Subject: [PATCH 1386/5214] media: rockchip: rga: reuse cmdbuf contents
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reuse the command buffer contents instead of completely writing it
for every frame. Therefore we only need to replace the source and
destination addresses for each frame. This reduces the amount of CPU
and memory operations done in each frame. A new cmdbuf_dirty flag notes
if the cmdbuf has to be rewritten on the next frame.

The initial idea of initializing the cmdbuf on streamon broke the

Subject: [PATCH 1387/5214] media: rockchip: rga: check scaling factor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Check the scaling factor to avoid potential problems. This is relevant
for the upcoming RGA3 support, as it can hang when the scaling factor
is exceeded.

The check is done at streamon when the other side is already streaming
to avoid incorrectly failing if the application configures the other
side after calling streamon. As try_fmt shouldn't be state aware,
it cannot be used to limit the format based on the scaling factor.
Therefore the check is done just before the actual streaming would be
started.

As the driver allows changing the rotation and selection while
streaming, add additional checks to ensure these changes
don't exceed the scaling factor.

Subject: [PATCH 1389/5214] media: rockchip: rga: change offset to
 dma_addresses
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change the offset to dma_addresses, as the current naming is misleading.
The offset naming comes from the fact that it references the offset in
the mapped iommu address space. But from the hardware point of view this
is an address, as also pointed out by the register naming
(e.g. RGA_DST_Y_RGB_BASE_ADDR). Therefore also change the type to
dma_addr_t, as with an external iommu driver this would also be the
correct type.

This change is a preparation for the RGA3 support, which uses an external
iommu and therefore just gets an dma_addr_t for each buffer. The field
renaming allows to reuse the existing fields of rga_vb_buffer to store
these values.

Subject: [PATCH 1390/5214] media: rockchip: rga: support external iommus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In preparation for the RGA3 add support for external iommus. This is a
transition step to just disable the RGA2 specific mmu table setup code.

Currently a simple rga_hw struct field is used to set the internal iommu.
But to handle the case of more sophisticated detection mechanisms
(e.g. check for an iommu property in the device tree), it is abstracted
by an inline function.

The RGA3 and the corresponding iommu share the interrupt. So in that
case, request a shared interrupt so that the iommu driver can request
it as well.

The size member is only used for the mmu page table mapping.
Therefore avoid storing the value and instead only calculate it
in place. This also avoids the calculation entirely when an external
iommu is used.

Subject: [PATCH 1393/5214] media: rockchip: rga: remove stride from rga_frame
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the stride variable from rga_frame. Despite the comment it
didn't involve any calculation and is just a copy of the
plane_fmt[0].bytesperline value. Therefore avoid this struct member
and use the bytesperline value directly in the places where it is
required.

Also drop the dependency on the depth format member, which was only
used to calculate the stride of the default format. This is already done
by the v4l2_fill_pixfmt_mp_aligned helper and used as stride in try_fmt.
Therefore using it's value also for the default format stride is just
more consistent.

Subject: [PATCH 1394/5214] media: rockchip: rga: move rga_fmt to rga-hw.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move rga_fmt to rga-hw in preparation of the RGA3 addition, as the struct
contains many RGA2 specific values. They are used to write the correct
register values quickly based on the chosen format. Therefore the
pointer to the rga_fmt struct is kept but changed to an opaque void
pointer outside of the rga-hw.h.

To enumerate and set the correct formats, two helper functions need to
be exposed in the rga_hw struct:

enum_format just get's the vidioc_enum_fmt format and it's return value
is also returned from vidioc_enum_fmt. This is a simple pass-through,
as the implementation is very simple.

adjust_and_map_format is a simple abstraction around the previous
rga_find_format. But unlike rga_find_format, it always returns a valid
format. Therefore the passed format value is also a pointer to update
it in case the values are not supported by the hardware.
Due to the RGA3 supporting different formats on the capture and output
side, an additional parameter is_capture has been added to support
this use-case. The additional ctx parameter is also added to allow the
RGA3 to limit the colorimetry only if an RGB<->YCrCb transformation
happens.

In preparation to the RGA3 addition add feature flags, which can limit
the exposed feature set of the video device, like rotating or selection
support. This is necessary as the RGA3 doesn't initially implement the
full feature set currently exposed by the driver.

Subject: [PATCH 1396/5214] media: rockchip: rga: disable multi-core support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Disable multi-core support in preparation of the RGA3 addition. The
RK3588 SoC features two equal RGA3 cores. This allows scheduling of the
work between both cores, which is not yet implemented. Until it is
implemented avoid exposing both cores as independent video devices to
prevent an ABI breakage when multi-core support is added.

This patch is copied from the Hantro driver patch to disable multi core
support by Sebastian Reichel. See
commit ccdeb8d57f7f ("media: hantro: Disable multicore support")

Subject: [PATCH 1397/5214] media: rockchip: rga: add rga3 support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for the RGA3 unit contained in the RK3588.

Only a basic feature set consisting of scaling and color conversion is
implemented. Currently unimplemented features include:
- Advanced formats like 10bit YUV, FBCE mode and Tile8x8 mode
- Background color (V4L2_CID_BG_COLOR)
- Configurable alpha value (V4L2_CID_ALPHA_COMPONENT)
- Image flipping (V4L2_CID_HFLIP and V4L2_CID_VFLIP)
- Image rotation (V4L2_CID_ROTATE)
- Image cropping/composing (VIDIOC_S_SELECTION)
  - Only very basic output cropping for 1088 -> 1080 cases is implemented

The register address defines were copied from the
vendor Rockchip kernel sources and slightly adjusted to not start at 0
again for the cmd registers.

During testing it has been noted that the scaling of the hardware is
slightly incorrect. A test conversion of 128x128 RGBA to 256x256 RGBA
causes a slightly larger scaling. The scaling is suddle, as it seems
that the image is scaled to a 2px larger version and then cropped to
it's final size. Trying to use the RGA2 scaling factor calculation
didn't work. As the calculation matches the vendor kernel driver, no
further research has been utilized to check if there may be some kind of
better scaling factor calculation.

Furthermore comparing the RGA3 conversion with the GStreamer
videoconvertscale element, the chroma-site is different. A quick testing
didn't reveal a chroma-site that creates the same image with the
GStreamer Element. Also when converting from YUV to RGB the RGB values
differ by 1 or 2. This doesn't seem to be a colorspace conversion issue
but rather a slightly different precision on the calculation.

Subject: [PATCH 1398/5214] media: cedrus: clean up media device on probe
 failure

cedrus_probe() initializes the media device before registering the video
device, the media controller, and the media device. If any of those later
steps fails, probe returns without calling media_device_cleanup(), so the
media device internals initialized by media_device_init() are left behind.

Add a media-device cleanup label to the probe unwind path and route video
registration failures through it as well.

Subject: [PATCH 1400/5214] media: meson: vdec: Fix memory leak in error path
 of vdec_open

The vdec_open() function previously jumped directly to
err_m2m_release when vdec_init_ctrls() failed, skipping
release of the m2m context. This caused a resource leak.

Fix it by introducing a proper err_m2m_ctx_release label
that calls v4l2_m2m_ctx_release(sess->m2m_ctx) before
releasing the m2m device.

This was identified via kmemleak:
unreferenced object 0xffff0000205d6878 (size 8):
  comm "v4l_id", pid 5289, jiffies 4294938580

so make it static and remove the unnecessary declaration from
the header file.

Convert the private helper _rtw_enqueue_cmd() to return 0 on
success instead of the legacy _SUCCESS value.

Keep rtw_enqueue_cmd() translating the result back to the
existing return convention for now.

Subject: [PATCH 1420/5214] staging: rtl8723bs: propagate errno through hal
 xmit path

Propagate errno values from rtl8723bs_hal_xmitframe_enqueue()
through rtw_hal_xmitframe_enqueue() by returning the error code
directly.

Update rtw_hal_xmit() to explicitly map the boolean return
value of rtl8723bs_hal_xmit() to _SUCCESS/_FAIL, clarifying
the return semantics at the HAL boundary.

None of the callers of rtw_hal_xmitframe_enqueue() check the
return value, so they do not need to be updated. This change
does not affect runtime behavior.

 statement

This switch statement doesn't do anything in all of its branches. As
such we can clean it up, and only keep the assignment in the else block.

Subject: [PATCH 1424/5214] staging: most: video: avoid double free on video
 register failure

comp_register_videodev() allocates a video_device with
video_device_alloc() and releases it if video_register_device() fails.

This can double free the video_device when __video_register_device()
reaches device_register() and that call fails:

  video_register_device()
    -> __video_register_device()
       -> device_register() fails
          -> put_device(&vdev->dev)
             -> v4l2_device_release()
                -> vdev->release(vdev)
                   -> video_device_release(vdev)

  comp_register_videodev()
    -> video_device_release(mdev->vdev)

Use video_device_release_empty() while registering the device so that
registration failure paths do not free mdev->vdev through vdev->release().
comp_register_videodev() then releases mdev->vdev exactly once on failure.
Restore video_device_release() after successful registration so the
registered device keeps its normal lifetime handling.

This issue was found by a static analysis tool I am developing.

Subject: [PATCH 1425/5214] thunderbolt: Move pci_device out of tb_nhi

Not all USB4/TB implementations are based on a PCIe-attached
controller. In order to make way for these, start off with moving the
pci_device reference out of the main tb_nhi structure.

Encapsulate the existing struct in a new tb_nhi_pci, that shall also
house all properties that relate to the parent bus. Similarly, any
other type of controller will be expected to contain tb_nhi as a
member.

Subject: [PATCH 1426/5214] thunderbolt: Separate out common NHI bits

Add a new file encapsulating most of the PCI NHI specifics
(intentionally leaving some odd cookies behind to make the layering
simpler). Most notably, separate out nhi_probe() to make it easier to
register other types of NHIs.

Also, fold in Intel Icelake (nhi_ops.c) support to contain all
PCIe-related bits in pci.c.

Subject: [PATCH 1427/5214] thunderbolt: Require nhi->ops be valid

Because of how fundamental ops->init_interrupts() is, it no longer
makes sense to consider cases where nhi->ops is NULL.

Drop some boilerplate around it and add a single sanity-check in
nhi_probe() instead.

Currently there's a lot of silent error-return paths in various places
where nhi_probe() can fail. Sprinkle some prints to make it clearer
where the problem is.

Subject: [PATCH 1429/5214] ipmi: Fix user refcount underflow in event delivery

ipmi_alloc_recv_msg(user) takes the temporary user reference owned by the
receive message, and ipmi_free_recv_msg() drops it again. If event delivery
fails after allocating receive messages for earlier users,
handle_read_event_rsp() rolls those messages back with
ipmi_free_recv_msg().

That rollback path still drops user->refcount explicitly after freeing each
message. The extra put can free a user that remains linked on intf->users,
so later event delivery may dereference a freed user or trip refcount_t's
addition-on-zero warning when ipmi_alloc_recv_msg() tries to acquire
another reference.

Remove the stale explicit put and the now-dead user assignment. Keep the
list_del() and ipmi_free_recv_msg() calls; they are the required rollback
operations.

Fixes: b52da4054ee0 ("ipmi: Rework user message limit handling")

The kernel-doc comment for dwc3_alloc_event_buffers states that the
function "Allocates @num event buffers", but the function does not have
a @num parameter and only allocates a single event buffer.

Remove the misleading "@num" reference from the brief description to
accurately reflect the function's behavior.

Subject: [PATCH 1438/5214] usb: atm: ueagle-atm: use dev_dbg() for 'device
 found' message

Convert dev_info() to dev_dbg().

Per 'Documentation/process/coding-style.rst':

  13) Printing kernel messages

  ...  When drivers are working properly they are quiet,
  so prefer to use dev_dbg/pr_debug unless something is wrong.

While in there, correct the verb form and add 'with' for clarity.

Subject: [PATCH 1440/5214] usb: xhci-pci: add AMD Promontory 21 PCI glue

AMD Promontory 21 (PROM21) xHCI PCI functions use the common xhci-pci
core for USB operation, but also expose controller-specific sensor data.
Add a small PROM21 PCI glue driver for AMD 1022:43fc and 1022:43fd
controllers.

The glue delegates USB host operation to the common xhci-pci core and
publishes a "hwmon" auxiliary device with parent-provided MMIO data.
Auxiliary device creation failure is logged but does not fail the xHCI
probe.

Make the PROM21 glue a hidden Kconfig tristate driven by the user-visible
SENSORS_PROM21_XHCI option. If sensor support is disabled, generic
xhci-pci binds PROM21 controllers normally. If sensor support is enabled,
the glue follows USB_XHCI_PCI.

This keeps the auxiliary device available for a modular sensor driver while
avoiding a built-in xhci-pci core handing PROM21 controllers to a glue
driver that is only available as a module during initramfs.

Subject: [PATCH 1441/5214] hwmon: add AMD Promontory 21 xHCI temperature
 sensor support

Add an auxiliary-bus hwmon driver for the temperature sensor exposed by
AMD Promontory 21 (PROM21) xHCI PCI functions. The driver binds to the
"hwmon" auxiliary device published by the PROM21 xHCI PCI glue and
exposes the sensor as temp1_input under the prom21_xhci hwmon device.

The sensor is accessed through a PROM21 vendor index/data register pair
in the xHCI PCI MMIO BAR. The driver consumes parent-provided MMIO data
from the PROM21 PCI glue instead of inspecting the parent PCI driver's
drvdata. The read path restores the previous vendor index value after
sampling and does not runtime-resume the parent PCI device; reads from a
suspended parent return -ENODATA.

Document the supported device, register access, runtime PM behavior, and
sysfs lookup method. The documentation also records the observation
method used to identify the register pair and derive the conversion
formula.

+Description
+-----------
+
+This driver exposes the temperature sensor in AMD PROM21 xHCI controllers.
+
+The driver binds to an auxiliary device created by the xHCI PCI driver for
+supported controllers. The sensor value is accessed through a vendor-specific
+index/data register pair in the controller's PCI MMIO BAR.
+The auxiliary device is created by the ``xhci-pci-prom21`` PCI glue driver.
+USB host operation is otherwise delegated to the common ``xhci-pci`` code.
+
+PROM21 is an AMD chipset IP used in single-chip or daisy-chained configurations
+to build AMD 6xx/8xx series chipsets. Since the xHCI controllers are
+integrated in PROM21, this temperature can also be used as a monitor for a
+temperature close to the AMD chipset temperature.

+
+The temperature value is read through a vendor-specific index/data register
+pair in the xHCI PCI MMIO BAR. The driver uses the following byte offsets from
+the MMIO BAR base:
+
+======================= =====================================================
+0x3000			Vendor index register
+0x3008			Vendor data register
+======================= =====================================================
+
+The driver saves the current vendor index register value, writes the
+temperature selector ``0x0001e520`` to the vendor index register, reads the
+vendor data register, and restores the previous vendor index value before
+returning. The raw temperature value is the low 8 bits of the vendor data
+register value.
+
+The hwmon core serializes this driver's callbacks, and the driver restores the
+previous index value after each read. This does not provide synchronization
+with firmware, SMM, ACPI AML, or any other user outside this driver.
+
+No public AMD reference is available for the register pair or the raw value.
+The register pair was identified on an X870E system with two PROM21 xHCI
+controllers. One controller was passed through to a Windows VM, and the same
+controller's PCI MMIO BAR was observed from the Linux host while HWiNFO64 was
+reporting the PROM21 xHCI temperature. In the test environment, the reported
+temperature was very stable at idle and the displayed sensor resolution was
+low, which made it possible to look for a consistently repeating MMIO response
+for the same reported temperature. During observation, offset 0x3000 repeatedly
+contained selector ``0x0001e520``. Writing the same selector to offset 0x3000
+from Linux and then reading offset 0x3008 reproduced the same raw value, so the
+offsets are treated as a vendor index/data register pair.
+
+The conversion formula was empirically inferred by matching observed raw
+8-bit values against HWiNFO64's reported PROM21 xHCI temperature for the same
+controller. The observed mapping is:
+
+  temp[C] = raw * 0.9066 - 78.624
+
+Runtime PM
+----------
+
+The driver does not wake the xHCI PCI device for hwmon reads. It reads the
+temperature only when the parent device is already active. A read from a
+suspended device returns ``-ENODATA``. After a successful read, the driver
+drops its active-only runtime PM reference and lets the PM core re-evaluate the
+idle state.
+
+Sysfs entries
+-------------
+
+======================= =====================================================
+temp1_input		Temperature in millidegrees Celsius
+======================= =====================================================
+
+The hwmon device name is ``prom21_xhci``. The sysfs path depends on the hwmon
+device number assigned by the kernel. Userspace can locate the device by
+matching the ``name`` attribute:
+
+.. code-block:: sh
+
+   for hwmon in /sys/class/hwmon/hwmon*; do
+           [ "$(cat "$hwmon/name")" = "prom21_xhci" ] || continue
+           cat "$hwmon/temp1_input"
+   done
+
+If the raw register value is invalid, ``temp1_input`` returns ``-ENODATA``.

+
+1. 使用方法
+~~~~~~~~~~~
+``drivers/usb/class/cdc-acm.c`` 驱动可用于符合 USB
+通信设备类抽象控制模型（USB CDC ACM）规范的
+USB 调制解调器和 USB ISDN 终端适配器。
+
+许多调制解调器支持此驱动，以下是我所知道的一些型号：
+
+	- 3Com OfficeConnect 56k
+	- 3Com Voice FaxModem Pro
+	- 3Com Sportster
+	- MultiTech MultiModem 56k
+	- Zoom 2986L FaxModem
+	- Compaq 56k FaxModem
+	- ELSA Microlink 56k
+
+我知道有一款 ISDN 终端适配器可以与 ACM 驱动一起使用：
+
+	- 3Com USR ISDN Pro TA
+
+一些手机也可以通过 USB 连接。
+我知道以下机型可以正常工作：
+
+	- SonyEricsson K800i
+
+遗憾的是，许多调制解调器和大多数 ISDN TA
+都使用专有接口，因此无法与此驱动配合工作。
+购买前请先确认设备是否符合 ACM 规范。
+
+要使用这些调制解调器，需要加载以下模块::
+
+	usbcore.ko
+	uhci-hcd.ko ohci-hcd.ko or ehci-hcd.ko
+	cdc-acm.ko
+
+之后就应该可以访问这些调制解调器了。
+应当可以使用 ``minicom``、``ppp`` 和 ``mgetty``
+与它们通信。
+
+2. 验证驱动是否正常工作
+~~~~~~~~~~~~~~~~~~~~~~~
+
+第一步是检查 ``/sys/kernel/debug/usb/devices``，
+其内容应该类似如下::
+
+  T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh= 2
+  B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0
+  D:  Ver= 1.00 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
+  P:  Vendor=0000 ProdID=0000 Rev= 0.00
+  S:  Product=USB UHCI Root Hub
+  S:  SerialNumber=6800
+  C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=  0mA
+  I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
+  E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=255ms
+  T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
+  D:  Ver= 1.00 Cls=02(comm.) Sub=00 Prot=00 MxPS= 8 #Cfgs=  2
+  P:  Vendor=04c1 ProdID=008f Rev= 2.07
+  S:  Manufacturer=3Com Inc.
+  S:  Product=3Com U.S. Robotics Pro ISDN TA
+  S:  SerialNumber=UFT53A49BVT7
+  C:  #Ifs= 1 Cfg#= 1 Atr=60 MxPwr=  0mA
+  I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=acm
+  E:  Ad=85(I) Atr=02(Bulk) MxPS=  64 Ivl=  0ms
+  E:  Ad=04(O) Atr=02(Bulk) MxPS=  64 Ivl=  0ms
+  E:  Ad=81(I) Atr=03(Int.) MxPS=  16 Ivl=128ms
+  C:* #Ifs= 2 Cfg#= 2 Atr=60 MxPwr=  0mA
+  I:  If#= 0 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01 Driver=acm
+  E:  Ad=81(I) Atr=03(Int.) MxPS=  16 Ivl=128ms
+  I:  If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=acm
+  E:  Ad=85(I) Atr=02(Bulk) MxPS=  64 Ivl=  0ms
+  E:  Ad=04(O) Atr=02(Bulk) MxPS=  64 Ivl=  0ms
+
+这三行的存在很关键（以及 ``Cls=`` 字段里出现的
+``comm`` 和 ``data`` 类）；它说明这是一个 ACM
+设备。``Driver=acm`` 表示该设备正在使用 acm 驱动。
+如果只看到 ``Cls=ff(vend.)``，那就无能为力了：

+=============================
+授权或禁止 USB 设备连接到系统
+=============================
+
+版权 (C) 2007 Inaky Perez-Gonzalez
+<inaky@linux.intel.com> 英特尔公司
+
+此功能允许你控制 USB 设备是否可以在系统中使用。
+借助它，你可以完全通过用户空间实现对 USB 设备的锁定。
+
+目前，当插入一个 USB 设备时，系统会对其进行配置，
+其接口会立即向用户开放。
+有了这项改动，只有在 root 授权设备完成配置后，
+设备才可被使用。
+
+
+用法
+====
+
+授权设备接入::
+
+	$ echo 1 > /sys/bus/usb/devices/DEVICE/authorized
+
+取消对设备的授权::
+
+	$ echo 0 > /sys/bus/usb/devices/DEVICE/authorized
+
+将新连接到 ``hostX`` 的设备默认设为未授权（即锁定）::
+
+	$ echo 0 > /sys/bus/usb/devices/usbX/authorized_default
+
+解除锁定::
+
+	$ echo 1 > /sys/bus/usb/devices/usbX/authorized_default
+
+默认情况下，所有 USB 设备都是授权的。
+向 ``authorized_default`` 属性写入 ``2`` 会使内核
+默认只授权连接到内部 USB 端口的设备。
+
+系统锁定示例（比较粗糙）
+------------------------
+
+假设你想实现一个锁定功能，只允许类型为 XYZ 的设备接入
+（例如某台带有外露 USB 端口的自助服务终端）::
+
+  启动系统
+  rc.local ->
+
+   for host in /sys/bus/usb/devices/usb*
+   do
+      echo 0 > $host/authorized_default
+   done
+
+给 udev 挂一个脚本，用于处理新插入的 USB 设备::
+
+ if device_is_my_type $DEV
+ then
+   echo 1 > $device_path/authorized
+ done
+
+
+``device_is_my_type()`` 才是锁定方案真正见功夫的
+地方。仅仅检查 class、type 和 protocol 是否匹配
+某个值，是你能做出的最糟糕的安全验证之一；
+对想绕过它的人来说，这反而是最容易利用的方案。
+如果你需要真正安全的办法，那就该使用加密、
+证书认证之类的机制。把 USB 存储设备当作
+“钥匙”的一个简单例子可以是::
+
+ function device_is_my_type()
+ {
+   echo 1 > authorized		# 暂时授权它
+                                # FIXME: 确保没人能挂载它
+   mount DEVICENODE /mntpoint
+   sum=$(md5sum /mntpoint/.signature)
+   if [ $sum = $(cat /etc/lockdown/keysum) ]
+   then
+        echo "We are good, connected"
+        umount /mntpoint
+        # 再做一些额外处理，让其他人也能使用它
+   else
+        echo 0 > authorized
+   fi
+ }
+
+
+当然，这个例子很粗糙；真正要做的话，
+你会想用基于 PKI 的证书校验，这样就不必依赖
+共享密钥之类的东西。不过你应该已经明白意思了。
+任何拿到设备仿真工具包的人都能伪造描述符和设备信息。
+别信这个。
+
+接口授权
+--------
+
+也有类似的方法用于允许或拒绝特定 USB 接口。
+这使得你可以只阻止某个 USB 设备中的部分接口。
+
+授权接口::
+
+	$ echo 1 > /sys/bus/usb/devices/INTERFACE/authorized
+
+取消接口授权::
+
+	$ echo 0 > /sys/bus/usb/devices/INTERFACE/authorized
+
+也可以更改特定 USB 总线上新接口的默认授权值。
+
+默认允许接口::
+
+	$ echo 1 > /sys/bus/usb/devices/usbX/interface_authorized_default
+
+默认拒绝接口::
+
+	$ echo 0 > /sys/bus/usb/devices/usbX/interface_authorized_default
+
+默认情况下，
+``interface_authorized_default`` 位为 ``1``，
+因此所有接口默认都处于已授权状态。
+
+注意：
+  如果把一个先前未授权的接口改为已授权，
+  则必须通过将 ``INTERFACE`` 写入 ``/sys/bus/usb/drivers_probe``
+  来手动触发驱动探测。
+
+对于需要多个接口的驱动程序，应先授权所有必需接口，
+然后再触发驱动探测。这样做可以避免副作用。

+=============================
+ChipIdea 高速双角色控制器驱动
+=============================
+
+1. 如何测试 OTG FSM（HNP 和 SRP）
+---------------------------------
+
+下面以两块 Freescale i.MX6Q Sabre SD 开发板为例，
+说明如何通过 sysfs 输入文件演示 OTG 的 HNP 和 SRP 功能。
+
+1.1 如何使能 OTG FSM
+--------------------
+
+1.1.1 在 ``menuconfig`` 中选择 ``CONFIG_USB_OTG_FSM``，并重新编译内核
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+重新构建内核镜像和模块。如果想查看 OTG FSM 的
+一些内部变量，可以挂载 ``debugfs``；其中有两个文件
+可以显示 OTG FSM 变量以及部分控制器寄存器的值::
+
+	cat /sys/kernel/debug/ci_hdrc.0/otg
+	cat /sys/kernel/debug/ci_hdrc.0/registers
+
+1.1.2 在控制器节点对应的 ``dts`` 文件中添加以下条目
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+	otg-rev = <0x0200>;
+	adp-disable;
+
+1.2 测试步骤
+------------
+
+1) 给两块 Freescale i.MX6Q Sabre SD 开发板上电，
+   并加载 gadget 类驱动（例如 ``g_mass_storage``）。
+
+2) 用 USB 线连接两块开发板：
+   一端是 micro A 插头，另一端是 micro B 插头。
+
+   插入 micro A 插头的一端是 A 设备，它应枚举另一端的 B 设备。
+
+3) 角色切换
+
+   在 B 设备上执行::
+
+	echo 1 > /sys/bus/platform/devices/ci_hdrc.0/inputs/b_bus_req
+
+   B 设备应接管主机角色并枚举 A 设备。
+
+4) A 设备切回主机角色
+
+   在 B 设备上执行::
+
+	echo 0 > /sys/bus/platform/devices/ci_hdrc.0/inputs/b_bus_req
+
+   或者，通过引入 HNP 轮询，B 端主机可以知道
+   A 端外设希望切换为主机角色，因此这次角色切换
+   也可以通过 A 端外设响应 B 端主机的轮询，
+   在 A 侧触发。
+   这可以通过在 A 设备上执行下面的命令来完成::
+
+	echo 1 > /sys/bus/platform/devices/ci_hdrc.0/inputs/a_bus_req
+
+   A 设备应切回主机角色并枚举 B 设备。
+
+5) 拔掉 B 设备（拔掉 micro B 插头），
+   并在 10 秒内重新插入；
+   A 设备应重新枚举 B 设备。
+
+6) 拔掉 B 设备（拔掉 micro B 插头），
+   并在 10 秒后重新插入；
+   A 设备不应重新枚举 B 设备。
+
+   如果 A 设备希望使用总线：
+
+   在 A 设备上执行::
+
+	echo 0 > /sys/bus/platform/devices/ci_hdrc.0/inputs/a_bus_drop
+	echo 1 > /sys/bus/platform/devices/ci_hdrc.0/inputs/a_bus_req
+
+   如果 B 设备希望使用总线：
+
+   在 B 设备上执行::
+
+	echo 1 > /sys/bus/platform/devices/ci_hdrc.0/inputs/b_bus_req
+
+7) A 设备关闭总线供电
+
+   在 A 设备上执行::
+
+	echo 1 > /sys/bus/platform/devices/ci_hdrc.0/inputs/a_bus_drop
+
+   A 设备应断开与 B 设备的连接，并关闭总线供电。
+
+8) B 设备发出 SRP 数据脉冲
+
+   在 B 设备上执行::
+
+	echo 1 > /sys/bus/platform/devices/ci_hdrc.0/inputs/b_bus_req
+
+   A 设备应恢复 USB 总线并枚举 B 设备。
+
+1.3 参考文档

+《On-The-Go and Embedded Host Supplement
+to the USB Revision 2.0 Specification
+July 27, 2012 Revision 2.0 version 1.1a》
+
+2. 如何将 USB 用作系统唤醒源
+----------------------------
+下面是在 i.MX6 平台上把 USB 用作系统唤醒源的示例。
+
+2.1 使能核心控制器的唤醒功能::
+
+	echo enabled > /sys/bus/platform/devices/ci_hdrc.0/power/wakeup
+
+2.2 使能 glue 层的唤醒功能::
+
+	echo enabled > /sys/bus/platform/devices/2184000.usb/power/wakeup
+
+2.3 使能 PHY 的唤醒功能（可选）::
+
+	echo enabled > /sys/bus/platform/devices/20c9000.usbphy/power/wakeup
+
+2.4 使能根集线器的唤醒功能::
+
+	echo enabled > /sys/bus/usb/devices/usb1/power/wakeup
+
+2.5 使能相关设备的唤醒功能::
+
+	echo enabled > /sys/bus/usb/devices/1-1/power/wakeup
+
+如果系统只有一个 USB 端口，
+而你希望在该端口上启用 USB 唤醒功能，
+可以使用下面的脚本::
+
+	for i in $(find /sys -name wakeup | grep usb);do echo enabled > $i;done;

+DWC3 驱动
+=========
+
+
+待办
+~~~~
+
+阅读时如果想顺手认领点任务，可以从下面挑一项 :)
+
+- 将中断处理程序改为每个端点各自使用线程化 IRQ
+
+  事实证明，有些 DWC3 命令大约需要 ``~1 ms`` 才能完成。
+  当前代码会一直自旋等待命令完成，这种设计并不好。
+
+  实现思路：
+
+  - DWC 核心实现了一个按端点对中断进行解复用的 IRQ 控制器。
+    中断号在探测（``probe``）阶段分配，并归属于该设备。
+    如果硬件通过 ``MSI`` 为每个端点提供独立中断，
+    那么这个“虚拟”IRQ 控制器就可以被真实的端点中断取代。
+
+  - 在调用 ``usb_ep_enable()`` 时请求并分配中断资源，
+    在调用 ``usb_ep_disable()`` 时释放中断资源。
+    最坏情况下需要 32 个中断，最少是 ``ep0/1`` 的两个中断。
+  - ``dwc3_send_gadget_ep_cmd()`` 将在 ``wait_for_completion_timeout()``
+    中休眠，直到命令完成。
+  - 中断处理程序分为以下几个部分：
+
+    - 设备级主中断处理程序
+      遍历每个事件，并对其调用 ``generic_handle_irq()``。
+      从 ``generic_handle_irq()`` 返回后，确认事件计数器，使中断最终消失。
+
+    - 设备级线程化处理程序
+      无。
+
+    - 端点中断的主处理程序
+      读取事件并尽量处理它。凡是需要睡眠的操作都交给线程处理。
+      事件保存在每个端点的数据结构中。
+      还要注意，一旦把某项工作交给线程处理，
+      就不要再在主处理程序里处理它，
+      以免出现优先级反转之类的问题。
+
+    - 端点中断的线程化处理程序
+      处理剩余的端点工作，这些工作可能会睡眠，例如等待命令完成。
+
+  延迟:
+
+   不应增加延迟，因为中断线程具有较高优先级，
+   会在普通用户态任务之前运行
+   （除非用户更改了调度优先级）。

+EHCI 驱动
+=========
+
+2002年12月27日
+
+EHCI 驱动用于通过支持 USB 2.0 的主机控制器
+硬件与高速 USB 2.0 设备通信。USB 2.0 兼容
+USB 1.1 标准，它定义了三种传输速率：
+
+    - “高速”（High Speed）480 Mbit/sec（60 MByte/sec）
+    - “全速”（Full Speed）12 Mbit/sec（1.5 MByte/sec）
+    - “低速”（Low Speed）1.5 Mbit/sec
+
+USB 1.1 仅支持全速与低速。
+高速设备可以在 USB 1.1 系统上使用，
+但速度会降到 USB 1.1 的速率。
+
+USB 1.1 设备也可以在 USB 2.0 系统上使用。当它们
+插入 EHCI 控制器时，会被交由 USB 1.1 的伴随
+（companion）控制器处理，该控制器通常是 OHCI 或 UHCI。
+
+当 USB 1.1 设备插入 USB 2.0 集线器时，它们通过
+集线器中的事务转换器（Transaction Translator，TT）
+与 EHCI 控制器交互，该转换器将低速或全速事务转换为
+高速分割事务，从而避免浪费传输带宽。
+
+截至本文撰写时，该驱动已在以下 EHCI 实现上成功运行
+（按字母顺序）：Intel、NEC、Philips 和 VIA。
+其他供应商的 EHCI 实现正在陆续问世；
+预计该驱动在这些实现上也可正常运行。
+
+自 2001 年年中起，usb-storage 设备就已可用
+（在 2.4 版该驱动上速度相当不错），
+集线器则直到 2001 年底才开始可用，而其他类型的高速设备
+似乎要等到更多系统内置 USB 2.0 后才会出现。
+这类新系统从 2002 年初开始上市，
+并在 2002 年下半年变得更加常见。
+
+注意，USB 2.0 支持并不只是 EHCI 本身。
+它还需要对 Linux-USB 核心 API 作出其他修改，
+包括 hub 驱动；不过这些修改并不需要真正改变
+暴露给 USB 设备驱动的基本 ``usbcore`` API。
+
+- David Brownell
+  <dbrownell@users.sourceforge.net>
+
+
+功能
+====
+
+该驱动会定期在 x86 硬件上进行测试，
+也已在 PPC 硬件上使用，因此大小端问题应当已经解决。
+因此可以认为，它已经处理好了所有必要的 PCI 细节，
+所以即便在 DMA 映射有些特殊的系统上，
+I/O 也应能正常运行。

+截至本文撰写时，该驱动应当已经能够很好地处理
+所有控制传输、批量传输和中断传输，
+包括通过 USB 2.0 集线器中的事务转换器
+与 USB 1.1 设备通信；但仍可能存在 bug。
+
+高速等时（ISO）传输支持也已可用，但截至本文撰写时，
+还没有 Linux 驱动使用这项支持。
+
+目前尚不支持通过事务转换器实现全速等时传输。
+需要注意，ISO 传输的 split transaction 支持
+与高速 ISO 传输几乎无法共用代码，
+因为 EHCI 用不同的数据结构表示它们。
+因此，目前大多数 USB 音频和视频设备
+还不能通过高速总线连接使用。
+
+驱动行为
+--------
+
+所有类型的传输都可以排队。
+这意味着来自一个接口驱动的控制传输
+（或通过 usbfs 发出的控制传输）不会干扰
+另一个驱动的控制传输，而且中断传输可以使用 1 帧的周期，
+而不必担心中断处理开销导致的数据丢失。
+
+
+EHCI 根集线器代码会将 USB 1.1 设备移交给其伴随控制器。
+该驱动不需要了解那些驱动的任何细节；
+一个原本就能正常工作的 OHCI 或 UHCI 驱动，
+并不会因为 EHCI 驱动也存在而需要更改。
+
+电源管理方面还有一些问题；
+当前挂起/恢复的行为还不完全正确。
+
+此外，在调度周期性事务
+（中断和等时传输）时还采取了一些简化处理。
+这些简化会限制可调度的周期性事务数量，
+并且无法使用小于一帧的轮询间隔。
+
+使用方式
+========
+
+假设有一个 EHCI 控制器（位于 PCI 卡或主板上），
+并且已将此驱动编译为模块，可这样加载::
+
+    # modprobe ehci-hcd
+
+卸载方式::
+
+    # rmmod ehci-hcd
+
+还应加载一个伴随控制器驱动，
+例如 ``ohci-hcd`` 或 ``uhci-hcd``。
+如果 EHCI 驱动出现任何问题，只需卸载它的模块，
+随后该伴随控制器驱动就会接手
+此前由 EHCI 驱动处理的所有设备
+（但速度会降低）。
+
+模块参数（传给 ``modprobe``）包括：
+
+    log2_irq_thresh（默认值 0）：
+        默认中断延迟的 log2 值，单位是微帧。默认值 0 表示 1 个微帧
+        （125 微秒）。最大值 6 表示 2^6 = 64 个微帧。
+        该值控制 EHCI 控制器发出中断的频率。
+
+如果在 2.5 内核上使用此驱动，并且启用了 USB 调试支持，
+则会在任一 EHCI 控制器的 ``sysfs`` 目录中看到三个文件：
+
+    ``async``
+        转储异步调度，用于控制传输和批量传输。它会显示每个活动的 ``qh``
+        以及待处理的 ``qtd``，通常每个 ``urb`` 对应一个 ``qtd``。
+        （可以在 ``usb-storage`` 做磁盘 I/O 时看它；顺便观察请求队列！）
+
+    ``periodic``
+        转储周期性调度，用于中断传输和等时传输。不显示 ``qtd``。
+
+    ``registers``
+        显示控制器寄存器状态。
+
+这些文件的内容有助于定位驱动问题。
+
+
+设备驱动通常不需要关心自己是否运行在 EHCI 之上，
+但它们可能想检查
+``usb_device->speed == USB_SPEED_HIGH``。
+高速设备能做到全速（或低速）设备做不到的事，
+例如高带宽的周期性传输（中断或 ISO 传输）。
+另外，设备描述符中的某些值
+（例如周期性传输的轮询间隔）
+在高速模式下使用不同的编码方式。
+
+不过，一定要让设备驱动经过 USB 2.0 集线器的测试。
+当使用事务转换器时，这些集线器报告某些故障
+（例如断开连接）的方式会不同；
+已经见过一些驱动在遇到与 OHCI 或 UHCI
+所报告的不同故障时表现不佳。
+
+性能
+====
+
+USB 2.0 吞吐量主要受两个因素制约：
+主机控制器处理请求的速度，以及设备响应这些请求的速度。
+480 Mbit/sec 的“原始传输率”对所有设备都成立，
+但总吞吐量还会受到诸如单个高速包之间的延迟、
+驱动是否足够聪明，以及系统整体负载等因素的影响。
+延迟也是性能考量因素。
+
+批量传输最常用于关注吞吐量的场景。
+需要记住的是，批量传输总是以 512 字节包为单位，
+而一个 USB 2.0 微帧中最多只能容纳 13 个这样的包。
+8 个 USB 2.0 微帧构成一个 USB 1.1 帧；
+一个微帧的时长是 1 毫秒 / 8 = 125 微秒。
+
+因此，只要硬件和设备驱动软件都允许，
+批量传输可提供超过 50 MByte/sec 的带宽。
+周期性传输模式（等时和中断）允许使用更大的包大小，
+从而可以逼近所宣称的 480 Mbit/sec 传输率。
+
+硬件性能
+--------
+
+截至本文撰写时，单个 USB 2.0 设备的最大传输速率
+通常约为 20 MByte/sec。
+这当然会随着时间改变：一些设备现在更快，一些更慢。
+
+第一代 NEC EHCI 实现似乎存在
+大约 28 MByte/sec 的硬件瓶颈。
+虽然这对单个 20 MByte/sec 的设备显然已经够用，
+但把三个这样的设备挂到同一总线上，
+并不能得到 60 MByte/sec。
+问题似乎在于控制器硬件无法并发进行 USB 与 PCI 访问，
+因此它每个微帧只会尝试 6 次（也许是 7 次）
+USB 事务，而不是 13 次。
+（对一个比其他产品早上市一年的芯片来说，
+这是个合理的妥协！）
+
+
+预计较新的实现会在这方面做得更好，
+通过投入更多芯片面积来解决这个问题，
+使新的主板芯片组更接近 60 MByte/sec 的目标。
+这既包括 NEC 的更新实现，也包括其他厂商的芯片。
+
+
+主机从 EHCI 控制器收到“请求已完成”中断的最小延迟
+为一个微帧（125 微秒）。该延迟可以调节；
+驱动提供了一个模块选项。默认情况下，
+``ehci-hcd`` 使用最小延迟，这意味着当发出一个控制
+或批量请求时，通常可以在不到 250 微秒内得知它已完成
+（具体取决于传输大小）。
+
+软件性能
+--------
+
+即便只是要达到 20 MByte/sec 的传输速率，
+Linux-USB 设备驱动也必须让 EHCI 队列始终保持满载。
+这意味着要发出较大的请求，
+或者在需要发出一连串小请求时使用批量请求排队。
+如果驱动未做到这一点，那么会直接从性能结果上表现出来。
+
+
+在典型情况下，使用 ``usb_bulk_msg()``
+以 4 KB 块循环写出，
+会浪费超过一半的 USB 2.0 带宽。
+I/O 完成与驱动发出下一次请求之间的延迟，
+通常会比一次 I/O 本身耗时更长。
+如果同样的循环改用 16 KB 块，会好一些；
+若使用一连串 128 KB 块，则浪费会少得多。
+
+
+但与其依赖这么大的 I/O 缓冲区来让同步 I/O 高效，
+不如直接向主机控制器排入多个（批量）请求，
+然后等待它们全部完成（或在出错时取消）。
+这种 URB 排队方式对所有 USB 1.1
+主机控制器驱动也同样适用。
+
+
+在 Linux 2.5 内核中，定义了新的 ``usb_sg_*()`` API；
+它们会把 scatterlist 中的所有缓冲区都排入队列。
+它们还使用 scatterlist 的 DMA 映射
+（其中可能应用 IOMMU）并减少中断次数，
+这些都有助于让高速传输尽可能快地运行。
+
+待办：
+   中断传输和等时（ISO）传输的性能问题。
+   这些周期性传输都是完全调度的，因此，主要问题可能在于如何触发高带宽模式。
+
+待办：
+   通过 ``sysfs`` 中的 ``uframe_periodic_max`` 参数，
+   可以分配超过标准 80% 的周期性带宽。
+   后续将对此进行说明。

+usbmon
+======
+
+简介
+====
+小写形式的 ``usbmon`` 指的是内核中的一项功能，
+用于收集 USB 总线上的 I/O 跟踪信息。它类似于网络监控工具
+``tcpdump(1)`` 或 Ethereal 所使用的数据包套接字。
+类似地，人们希望使用 usbdump 或 USBMon
+（首字母大写）之类的工具来检查
+usbmon 生成的原始跟踪数据。
+
+usbmon 报告的是各个外设驱动
+向主机控制器驱动（HCD）发出的请求。
+因此，如果 HCD 本身有 bug，那么 usbmon 报告的跟踪信息
+可能无法精确对应实际的总线事务。
+这和 tcpdump 的情况是一样的。
+
+目前实现了两种 API: ``text`` 和 ``binary``。
+二进制 API 通过 ``/dev`` 命名空间中的字符设备提供，
+并且属于 ABI。文本 API 自内核 2.6.35 起已废弃，
+但为了方便仍然可用。
+
+如何使用 usbmon 收集原始文本跟踪信息
+====================================
+
+与数据包套接字不同，usbmon 提供了一种接口，
+可以输出文本格式的跟踪信息。这样做有两个目的：
+第一，在更完善的格式最终确定之前，
+它作为工具间通用的跟踪交换格式；
+第二，在不使用工具的情况下，人们也可以直接阅读这些信息。
+
+要收集原始文本跟踪信息，请按以下步骤进行操作。
+
+1. 准备
+-------
+
+挂载 debugfs（内核配置中必须启用它），并加载 usbmon 模块
+（如果它是作为模块构建的）。如果 usbmon 已经编入内核，
+那么第二步可以省略。
+
+命令示例::
+
+    # mount -t debugfs none_debugs /sys/kernel/debug
+    # modprobe usbmon
+    #
+
+确认总线套接字是否存在::
+
+    # ls /sys/kernel/debug/usb/usbmon
+    0s  0u  1s  1t  1u  2s  2t  2u  3s  3t  3u  4s  4t  4u
+    #
+
+现在，你可以选择使用 ``0u`` 捕获所有总线上的数据包，
+并跳到第 3 步；
+也可以先按第 2 步找到目标设备所在的总线。
+这样可以过滤掉那些持续输出数据的烦人设备。
+
+2. 查找目标设备连接的是哪条总线
+-------------------------------
+
+运行 ``cat /sys/kernel/debug/usb/devices``，
+找到对应设备的 T 行。通常可以通过厂商字符串来查找。
+如果有许多类似设备，可以拔掉其中一个，
+再比较前后两次 ``/sys/kernel/debug/usb/devices``
+的输出。T 行里会包含总线编号。
+
+示例::
+
+  T:  Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
+  D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
+  P:  Vendor=0557 ProdID=2004 Rev= 1.00
+  S:  Manufacturer=ATEN
+  S:  Product=UC100KM V2.00
+
+``Bus=03`` 表示它位于 3 号总线上。或者，
+也可以查看 ``lsusb`` 的输出，并从对应行得到总线编号。
+
+示例如下::
+
+  Bus 003 Device 002: ID 0557:2004 ATEN UC100KM V2.00
+
+
+3. 启动 cat 命令
+----------------
+
+如果只监听单条总线，可执行::
+
+    # cat /sys/kernel/debug/usb/usbmon/3u > /tmp/1.mon.out
+
+否则，如果要监听所有总线，则执行::
+
+    # cat /sys/kernel/debug/usb/usbmon/0u > /tmp/1.mon.out
+
+此进程会一直读取，直到被终止。
+由于输出通常会很长，因此更推荐将输出重定向到某个位置。
+
+
+4. 在 USB 总线上执行期望的操作
+------------------------------
+
+此处需要执行一些会产生 USB 流量的动作，
+比如插入 U 盘、拷贝文件、操作摄像头等。
+
+
+5. 停止 cat
+-----------
+
+这一步通常通过键盘中断（Control-C）完成。
+
+此时输出文件（本例中为 ``/tmp/1.mon.out``）
+可以保存、通过电子邮件发送，或使用文本编辑器查看。
+如果使用最后一种方式，请确保文件不会大到编辑器无法打开。
+
+
+原始文本数据格式
+================
+
+目前支持两种格式：原始格式，也就是 ``1t`` 格式，
+以及 ``1u`` 格式。``1t`` 格式在内核 2.6.21 中已被废弃。
+``1u`` 格式增加了一些字段，例如 ISO 帧描述符、
+``interval`` 等。它生成的行会稍长一些，
+但在其他方面是 ``1t`` 格式的完整超集。
+
+如果程序需要区分上述两种格式，
+可以查看 ``address`` 字段（见下文）。
+如果其中有两个冒号，就是 ``1t`` 格式；
+否则是 ``1u`` 格式。
+
+任何文本格式的数据由一系列事件组成，
+如 URB 提交、URB 回调、提交错误等。
+每个事件对应单独的一行文本，
+由使用空白符间隔的若干字段组成。
+字段的数量与位置可能取决于事件类型，
+但以下字段对所有类型都通用：
+
+下面按从左到右的顺序列出这些共有字段：
+
+- URB Tag。用于标识 URB，通常是 URB 结构体在内核中的地址
+  （以十六进制表示），
+  但也可能是序号或其他合理的唯一字符串。
+
+- 时间戳（微秒），十进制数字。
+  时间戳的精度取决于可用时钟，
+  因此可能远差于
+  1 微秒（例如实现使用的是 jiffies）。
+
+- 事件类型。它表示的是事件的格式，而不是 URB 的类型。
+  可用值为：``S`` 表示提交，``C`` 表示回调，``E`` 表示提交错误。
+
+- ``Address`` 字段（以前称作 ``pipe``）。
+  它包含四个由冒号分隔的字段：
+  URB 类型及方向、总线号、设备地址和端点号。类型与方向的编码如下：
+
+    == ==   ==========================
+    Ci Co   控制输入和输出
+    Zi Zo   等时输入和输出
+    Ii Io   中断输入和输出
+    Bi Bo   批量输入和输出
+    == ==   ==========================
+
+  总线号、设备地址和端点号使用十进制，但可能有前导零。
+
+- URB 状态字段。这个字段要么是一个字母，
+  要么是几个由冒号分隔的数字：
+  URB 状态、``interval``、``start frame`` 和 ``error count``。
+  与 ``address`` 字段不同，除了状态外，其余字段都是可选的。
+  ``interval`` 只会为中断和等时 URB 打印；``start frame`` 只会为
+  等时 URB 打印；错误计数只会在等时回调事件中打印。
+
+  状态字段是一个十进制数字，有时为负数，
+  对应 URB 的 ``status`` 字段。
+  对于提交事件，这个字段本身没有实际意义，
+  但为了便于脚本解析，它仍然存在。
+  当发生错误时，该字段包含错误码。
+
+  在提交控制包时，这个字段包含的是 ``Setup Tag``，
+  而不是一组数字。
+  判断 ``Setup Tag`` 是否存在很容易，因为它从来不是数字。
+  因此，如果脚本在这个字段里发现的是一组数字，
+  就会继续读取数据长度（等时 URB 除外）。
+  如果发现的是其他内容，比如一个字母，
+  那么脚本会先读取 ``Setup`` 包，再读取数据长度或等时描述符。
+
+- ``Setup`` 包由 5 个字段组成：
+  ``bmRequestType``、``bRequest``、``wValue``、
+  ``wIndex`` 和 ``wLength``。这些字段由 USB 2.0 规范定义。
+  如果 ``Setup Tag`` 为 ``s``，就可以安全地解码这些字段。
+  否则，说明 Setup 包虽然存在，但并未被捕获，此时各字段中会填入占位内容。
+
+- 等时传输帧描述符的数量及其内容：
+  如果一个等时传输事件带有一组描述符，首先打印该 URB 中描述符的总数，
+  然后为每个描述符打印一个字段，最多打印 5 个字段。
+  每个字段由三个用冒号分隔的十进制数字组成，
+  分别表示状态（status）、偏移（offset）和长度（length）。
+  对于提交（submission），报告的是初始长度；
+  对于回调（callback），报告的是实际长度。
+
+- 数据长度：
+  对于提交，表示请求的长度；对于回调，表示实际传输的长度。
+
+- 数据标签：
+  即使数据长度非零，usbmon 也不一定会捕获数据。
+  仅当标签为 ``=`` 时，才会有数据字段。
+
+- 数据字段：
+  以大端十六进制格式显示。注意，这些并不是真正的机器字，
+  而只是把字节流拆成若干“字”以便阅读。因此最后一个字可能只包含
+  1 到 4 个字节。
+  收集的数据长度是有限的，可能小于数据长度字段中报告的值。
+  因为数据长度字段只统计实际接收到的字节，而数据字段包含整个传输缓冲区，
+  所以，在等时输入（Zi）完成且缓冲区中接收到的数据稀疏的情况下，
+  收集的数据长度可能大于数据长度字段的值。
+
+
+
+示例：
+
+获取端口状态的输入控制传输::
+
+    d5ea89a0 3575914555 S Ci:1:001:0 s a3 00 0000 0003 0004 4 <
+    d5ea89a0 3575914560 C Ci:1:001:0 0 4 = 01050000
+
+向地址为 5 的存储设备发送
+31 字节 Bulk 包装的 SCSI 命令 ``0x28``
+（``READ_10``）的输出批量传输::
+
+    dd65f0e8 4128379752 S Bo:1:005:2 -115 31 = 55534243 ad000000 00800000 80010a28 20000000 20000040 00000000 000000
+    dd65f0e8 4128379808 C Bo:1:005:2 0 31 >
+
+原始二进制格式与 API
+====================
+API 的整体架构与前文大体相同，只是事件以二进制格式传递。
+每个事件都通过下面的结构发送
+（这个名字是为了叙述方便而虚构的）::
+
+
+  struct usbmon_packet {
+	u64 id;			/*  0: URB ID - 从提交到回调 */
+	unsigned char type;	/*  8: 与文本相同；可扩展 */
+	unsigned char xfer_type; /*    ISO (0)、中断、控制、批量 (3) */
+	unsigned char epnum;	/*     端点号和传输方向 */
+	unsigned char devnum;	/*     设备地址 */
+	u16 busnum;		/* 12: 总线号 */
+	char flag_setup;	/* 14: 与文本相同 */
+	char flag_data;		/* 15: 与文本相同；二进制零也可 */
+	s64 ts_sec;		/* 16: gettimeofday */
+	s32 ts_usec;		/* 24: gettimeofday */
+	int status;		/* 28: */
+	unsigned int length;	/* 32: 数据长度（提交或实际） */
+	unsigned int len_cap;	/* 36: 已捕获的数据长度 */
+	union {			/* 40: */
+		unsigned char setup[SETUP_LEN];	/* 仅用于控制类 S 事件 */
+		struct iso_rec {		/* 仅用于 ISO */
+			int error_count;
+			int numdesc;
+		} iso;
+	} s;
+	int interval;		/* 48: 仅用于中断和 ISO */
+	int start_frame;	/* 52: 仅用于 ISO */
+	unsigned int xfer_flags; /* 56: URB 的 transfer_flags 副本 */
+	unsigned int ndesc;	/* 60: 实际 ISO 描述符数量 */
+  };				/* 64 总长度 */
+
+可以用 ``read(2)``、``ioctl(2)``，
+或者通过 ``mmap`` 访问缓冲区，
+从字符设备接收这些事件。
+不过，出于兼容性原因，``read(2)``
+只返回前 48 个字节。
+
+字符设备通常命名为 ``/dev/usbmonN``，
+其中 ``N`` 是 USB 总线号。
+编号为零的设备（``/dev/usbmon0``）比较特殊，
+表示“所有总线”。
+请注意，具体命名策略由 Linux 发行版决定。
+
+如果你手动创建 ``/dev/usbmon0``，
+请确保它归 root 所有，并且权限为 ``0600``。
+否则，非特权用户将能够窃听键盘流量。
+
+以下 ``MON_IOC_MAGIC`` 为 ``0x92`` 的 ioctl 调用可用：
+
+``MON_IOCQ_URB_LEN``，定义为 ``_IO(MON_IOC_MAGIC, 1)``
+
+该调用返回下一个事件的数据长度。
+注意大多数事件不包含数据，
+因此如果该调用返回零，并不意味着没有事件。
+
+``MON_IOCG_STATS``，定义为
+``_IOR(MON_IOC_MAGIC, 3, struct mon_bin_stats)``
+
+参数是指向以下结构的指针::
+
+  struct mon_bin_stats {
+	u32 queued;
+	u32 dropped;
+  };
+
+成员 ``queued`` 表示当前缓冲区中已经排队的事件数量，
+而不是自上次重置以来处理过的事件数量。
+
+成员 ``dropped`` 表示自上次调用
+``MON_IOCG_STATS`` 以来丢失的事件数量。
+
+``MON_IOCT_RING_SIZE``，定义为 ``_IO(MON_IOC_MAGIC, 4)``
+
+此调用设置缓冲区大小。参数为以字节为单位的缓冲区大小。
+大小可能会向下取整到下一个块（或页）。
+如果请求的大小超出该内核的 [未指定] 范围，
+则调用会失败并返回 ``-EINVAL``。
+
+``MON_IOCQ_RING_SIZE``，定义为 ``_IO(MON_IOC_MAGIC, 5)``
+
+该调用返回缓冲区当前大小（以字节为单位）。
+
+``MON_IOCX_GET``，定义为
+``_IOW(MON_IOC_MAGIC, 6, struct mon_get_arg)``
+``MON_IOCX_GETX``，定义为
+``_IOW(MON_IOC_MAGIC, 10, struct mon_get_arg)``
+
+如果内核缓冲区中没有事件，
+这些调用就会一直等待，直到有事件到达，
+然后返回第一个事件。
+参数是指向以下结构的指针::
+
+  struct mon_get_arg {
+	struct usbmon_packet *hdr;
+	void *data;
+	size_t alloc;		/* 数据长度可以为零 */
+  };
+
+
+调用前，应填好 ``hdr``、``data`` 和 ``alloc``。
+调用返回后，``hdr`` 指向的区域中包含下一个事件的结构；
+如果存在数据，那么数据缓冲区中也会包含相应数据。
+该事件会从内核缓冲区中移除。
+
+``MON_IOCX_GET`` 会将 48 字节的数据复制到 ``hdr`` 区域，
+``MON_IOCX_GETX`` 会复制 64 字节。
+
+``MON_IOCX_MFETCH``，定义为
+``_IOWR(MON_IOC_MAGIC, 7, struct mon_mfetch_arg)``
+
+当应用程序通过 ``mmap(2)`` 访问缓冲区时，
+主要使用这个 ioctl。
+其参数是指向以下结构的指针::
+
+  struct mon_mfetch_arg {
+	uint32_t *offvec;	/* 获取的事件偏移向量 */
+	uint32_t nfetch;	/* 要获取的事件数量（输出：已获取） */
+	uint32_t nflush;	/* 要刷新的事件数量 */
+  };
+
+
+该 ioctl 的操作分为三个阶段：
+
+首先，从内核缓冲区移除并丢弃最多 ``nflush`` 个事件。
+实际丢弃的事件数量会写回 ``nflush``。
+
+其次，除非伪设备以 ``O_NONBLOCK`` 打开，否则会一直等待，
+直到缓冲区中出现事件。
+
+第三，将最多 ``nfetch`` 个偏移量提取到 mmap
+缓冲区，并存入 ``offvec`` 中。
+实际提取到的事件偏移数量会存回 ``nfetch``。
+
+``MON_IOCH_MFLUSH``，定义为 ``_IO(MON_IOC_MAGIC, 8)``
+
+此调用从内核缓冲区移除若干事件。
+其参数为要移除的事件数量。
+如果缓冲区中的事件少于请求数量，
+则移除所有事件，且不报告错误。
+当没有事件时也可使用。
+
+``FIONBIO``
+
+如果有需要，将来可能会实现 ``FIONBIO`` ioctl。
+
+除了 ``ioctl(2)`` 和 ``read(2)`` 之外，
+二进制 API 的特殊文件也可以用 ``select(2)`` 和
+``poll(2)`` 轮询。
+但 ``lseek(2)`` 不起作用。
+
+* 二进制 API 的内核缓冲区内存映射访问
+
+基本思想很简单：
+
+准备时，先获取当前大小，再用 ``mmap(2)`` 映射缓冲区。
+然后执行类似下面伪代码的循环::
+
+   struct mon_mfetch_arg fetch;
+   struct usbmon_packet *hdr;
+   int nflush = 0;
+   for (;;) {
+      fetch.offvec = vec; // 有 N 个 32 位字
+      fetch.nfetch = N;   // 或者少于 N
+      fetch.nflush = nflush;
+      ioctl(fd, MON_IOCX_MFETCH, &fetch);   // 同时处理错误
+      nflush = fetch.nfetch;       // 完成后要刷新这么多包
+      for (i = 0; i < nflush; i++) {
+         hdr = (struct ubsmon_packet *) &mmap_area[vec[i]];
+         if (hdr->type == '@')     // 填充包
+            continue;
+         caddr_t data = &mmap_area[vec[i]] + 64;
+         process_packet(hdr, data);
+      }
+   }
+
+
+
+因此，主要思想是每 N 个事件只执行一次 ioctl。
+
+虽然缓冲区是环形的，但返回的头和数据不会跨越缓冲区末端，
+因此上面的伪代码无需任何合并操作。

Subject: [PATCH 1450/5214] usb: typec: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace in the list
terminator.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 1451/5214] usb: misc: Use named initializers for struct
 i2c_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

While touching all these arrays, unify usage of whitespace in the list
terminator.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 1454/5214] PCI: host-common: Add
 pci_host_common_d3cold_possible() helper

Add a common helper, pci_host_common_d3cold_possible(), to determine
whether PCIe devices under host bridge can safely transition to D3cold.

This helper is intended to be used by PCI host controller drivers to decide
whether they can safely put the endpoint devices into D3cold based on their
power state and wakeup capabilities. Once the devices are transitioned into
D3cold, the host controller can be safely powered off.

The helper walks all devices on the all downstream buses and only allows
the devices to enter D3cold if all PCIe endpoints are already in
PCI_D3hot. This ensures that the host controller driver does not broadcast
PME_Turn_Off or power down the controller while any active endpoint still
requires the link to remain powered.

For devices that may wake the system, the helper additionally requires that
the device supports PME wake from D3cold (via WAKE#). Devices that do not
have wakeup enabled are not restricted by this check and do not block the
devices under host bridge from entering D3cold.

Devices without a bound driver and with PCI not enabled via sysfs are
treated as inactive and therefore do not prevent the devices under host
bridge from entering D3cold. This allows controllers to power down more
aggressively when there are no actively managed endpoints.

Some devices (e.g. M.2 without auxiliary power) lose PME detection when
main power is removed. Even if such devices advertise PME-from-D3cold
capability, entering D3cold may break wakeup. Return PME-from-D3cold
capability via 'pme_capable' parameter so PCIe controller drivers can apply
platform-specific handling to preserve wakeup functionality.

Subject: [PATCH 1455/5214] PCI: qcom: Add .get_ltssm() callback to query LTSSM
 status

For older SoCs like SC7280, reading DBI LTSSM register after sending
PME_Turn_Off message causes NOC error.

To avoid unsafe DBI accesses, introduce qcom_pcie_get_ltssm() to retrieve
the LTSSM state without DBI. For newer platforms, read the LTSSM state from
the PARF_LTSSM register; for older platforms continue to retrieve it from
ELBI_SYS_STTS.

This helper is used in place of direct DBI-based link state checks in the
D3cold path after sending PME_Turn_Off message, ensuring the LTSSM state
can be queried safely even after DBI access is no longer valid.

Subject: [PATCH 1456/5214] PCI: qcom: Power down PHY via PARF_PHY_CTRL before
 disabling rails/clocks

Some Qcom PCIe controller variants bring the PHY out of test power-down
(PHY_TEST_PWR_DOWN) during init. When the link is later transitioned to
D3cold and the driver disables PCIe clocks and/or regulators without
explicitly re-asserting PHY_TEST_PWR_DOWN, the PHY can remain partially
powered, leading to avoidable power leakage.

Update the init-path comments to reflect that PARF_PHY_CTRL is used to
power the PHY on. Also, for controller revisions that enable PHY power in
init (2.3.2, 2.3.3, 2.4.0, 2.7.0 and 2.9.0), explicitly power the PHY down
via PARF_PHY_CTRL in the deinit path before disabling clocks or regulators.

This ensures the PHY is put into a defined low-power state prior to
removing its supplies, preventing leakage when entering D3cold.

Subject: [PATCH 1457/5214] PCI: dwc: Use common D3cold eligibility helper in
 suspend path

Previously, the driver skipped putting the link into L2 and device state in
D3cold whenever L1 ASPM was enabled, since some devices (e.g. NVMe) expect
low resume latency and may not tolerate deeper power states. However, such
devices typically remain in D0 and are already covered by the new helper's
requirement that all endpoints be in D3hot before the devices under host
bridge may enter D3cold.

Replace the local L1/L1SS-based check in dw_pcie_suspend_noirq() with the
shared pci_host_common_d3cold_possible() helper to decide whether the
devices under host bridge can safely transition to D3cold.

In addition, propagate PME-from-D3cold capability information from the
helper and record it in skip_pwrctrl_off. Some devices (e.g. M.2 cards
without auxiliary power) cannot send PME when the main power is removed,
even if they advertise PME-from-D3cold support. This allows controller
power-off to be skipped when required to preserve wakeup functionality.

While at it, update the 'dw_pcie::suspended' flag in dw_pcie_resume_noirq()
only after the PCIe link resumes successfully, to avoid marking the
controller as active when link resume fails.

Subject: [PATCH 1458/5214] PCI: qcom: Add D3cold support

Add support for transitioning PCIe endpoints under host bridge into D3cold
by integrating with the DWC core suspend/resume helpers.

Implement PME_Turn_Off message generation via ELBI_SYS_CTRL and hook it
into the DWC host operations so the controller follows the standard
PME_Turn_Off based power-down sequence before entering D3cold.

When the device is suspended into D3cold, fully tear down interconnect
bandwidth and OPP votes. If D3cold is not entered, retain existing
behavior by keeping the required interconnect and OPP votes.

Use dw_pcie::skip_pwrctrl_off to avoid powering off devices during suspend
to preserve wakeup capability of the devices and also not to power on the
devices in the init path.

Finally, drop the qcom_pcie::suspended flag and rely on the existing
dw_pcie::suspended state, which now drives both the power-management flow
and the interconnect/OPP handling.

Subject: [PATCH 1459/5214] perf build: Fix fsmount.o build

A merge conflict between:

commit 552636b9317c8a84 ("perf trace: Add beautifier script for fsmount flags")
commit 32969ef6e3e1979a ("perf build: Pre-generate BPF skeleton tooling during umbrella prepare phase")

Resulted in a missed build dependency in the linux-next merge:

commit 61da860eee0798d3 ("Merge branch 'perf-tools-next' of https://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git")

Fix the build by adding the necessary build dependencies.

Subject: [PATCH 1460/5214] selftests/landlock: Filter dealloc records in
 audit_count_records()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

audit_count_records() counts both AUDIT_LANDLOCK_DOMAIN allocation and
deallocation records in records.domain .  Domain deallocation is tied to
asynchronous credential freeing via kworker threads
(landlock_put_ruleset_deferred), so the dealloc record can arrive after
the drain in audit_init() and after the preceding audit_match_record()
call.  This causes flaky failures in tests that assert an exact
records.domain count: a stale dealloc record from a previous test's
domain inflates the count by one.

Observed on x86_64 under build configurations that delay the kworker
firing the dealloc callback (e.g. coverage instrumentation): the
audit_layout1 tests in fs_test.c intermittently saw records.domain == 2
where 1 was expected.  The fix is in the shared helper, so those
existing checks become robust without needing a fs_test.c edit.

Filter audit_count_records() with a regex to skip records containing
deallocation status.  The remaining domain records (allocation, emitted
synchronously during landlock_log_denial()) are deterministic.
Deallocation records are already tested explicitly via
matches_log_domain_deallocated() in audit_test.c, which uses its own
domain-ID-based filtering and longer timeout.

With this filter in place, re-add the records.domain == 0 checks that
were removed in commit 3647a4977fb7 ("selftests/landlock: Drain stale
audit records on init") as a workaround for this race.

Subject: [PATCH 1461/5214] selftests/landlock: Increase default audit socket
 timeout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

matches_log_fs() and other audit_match_record() callers intermittently
return -EAGAIN under heavy debug configs (KASAN, lockdep).  The audit
record delivery pipeline is asynchronous: landlock_log_denial() queues
the record to audit_queue, and kauditd_thread dequeues and delivers via
netlink.  Under debug configs, kauditd scheduling between
audit_log_end() and netlink_unicast() can exceed a syscall round trip
(more than 1 usec), which was the value of the socket timeout used for
the recvfrom() calls.

The observed failure [1] is an EAGAIN error code (-11) which means that
the access record had not arrived within the 1 usec timeout of
recvfrom().  The expected record does arrive, but only after
matches_log_fs() has already returned.  It is then consumed by a later
audit_count_records() call, making records.access == 1 instead of 0.

Switch the default socket timeout to the slow value (1 second) so all
audit_match_record() callers wait long enough for kauditd delivery, and
lower it to the fast value (1 usec) only on the two paths that expect no
record: audit_count_records() and the expected_domain_id == 0 probe in
matches_log_domain_deallocated().  audit_init() drains stale records
with the fast timeout (terminating on -EAGAIN once the backlog is empty)
and switches to the patient default before returning.  1 second gives
~10x margin over the observed maximum (~100 ms, while the happy path is
~23 us).

Rename the timeval constants to reflect their new roles:
- audit_tv_dom_drop (1 second) -> audit_tv_default: default socket
  timeout, patient enough for asynchronous kauditd delivery.
- audit_tv_default (1 usec) -> audit_tv_fast: fast timeout for paths
  that expect no record (drain, audit_count_records(), probes).

Invert the conditional in matches_log_domain_deallocated().  Check
setsockopt returns on both the lower and restore paths; preserve the
first error via !err when the restore fails after a prior error so the
actionable return code is not masked by a bookkeeping failure.

Subject: [PATCH 1462/5214] media: uvcvideo: Fix deadlock if uvc_status_stop is
 called from async_ctrl.work

If a UVC camera has an asynchronous control, uvc_status_stop may be
called from async_ctrl.work:

uvc_ctrl_status_event_work()
    uvc_ctrl_status_event()
        uvc_ctrl_clear_handle()
	    uvc_pm_put()
	        uvc_status_put()
		    uvc_status_stop()
		        cancel_work_sync()

This will cause a deadlock, since cancel_work_sync will wait for
uvc_ctrl_status_event_work to complete before returning.

Fix this by returning early from uvc_status_stop if we are currently in
the work function. flush_status now remains false until uvc_status_start
is called again, ensuring that uvc_ctrl_status_event_work won't resubmit
the URB.

Subject: [PATCH 1464/5214] media: uvcvideo: Avoid partial metadata buffers

If the metadata queue that is empty receives a new buffer while we are
in the middle of processing a frame, the first metadata buffer will
contain partial information.

Avoid this by tracking the state of the metadata buffer and making sure
that it is in sync with the data buffer.

Now that we are at it, make sure that we skip buffers of size 1 or 0.
They are not allowed by the spec... but it is a simple check to add and
better be safe than sorry.

Subject: [PATCH 1465/5214] media: uvcvideo: Fix dev_sof filtering in hw
 timestamp

To avoid filling the clock circular buffer with duplicated data we only
add it if the new value sof is different than the last added sof.

The issue is that we compare the unprocess sof with the processed sof.
If there is a sof_offset, or UVC_QUIRK_INVALID_DEVICE_SOF is enabled,
the comparison will not work as expected.

This patch moves the comparison to the right place.

Subject: [PATCH 1466/5214] media: uvcvideo: Use hw timestaming if the clock
 buffer is full

In some situations, even with a full clock buffer, it does not contain
250msec of data. This results in the driver jumping back from software
to hardware timestapsing creating a nasty artifact in the video.

If the clock buffer is full, use it to calculate the timestamp instead
of defaulting to software stamps, the reduced accuracy is less visible
than jumping from one timestamping mechanism to the other.

 small sof delta

Some UVC 1.1 cameras running in fast isochronous mode tend to spam the
USB host with a lot of empty packets. These packets contain clock
information and are added to the clock buffer but do not add any
accuracy to the calculation. In fact, it is quite the opposite, in our
calculations, only the first and the last timestamp is used, and we only
have 32 slots.

Ignore the samples that will produce less than MIN_HW_TIMESTAMP_DIFF
data.

Subject: [PATCH 1470/5214] media: uvcvideo: Only do uvc_video_get_time() if
 needed

There is no need to calculate the current time if the sample is going to
be filtered.

Move the assignment close to uvc_video_clock_add_sample().

Subject: [PATCH 1474/5214] KVM: VMX: Refresh GUEST_PENDING_DBG_EXCEPTIONS.BS
 on all injected #DBs

Move KVM's stuffing of GUEST_PENDING_DBG_EXCEPTIONS.BS when RFLAGS.TF=1 and
MOV/POP SS or STI blocking is active into the exception injection code so
that KVM fixes up the VMCS for all injected #DBs, not only those that are
reflected back into the guest after #DB interception.  E.g. if KVM queues
a #DB in the emulator, or more importantly if userspace does save/restore
exactly on the #DB+shadow boundary, then KVM needs to massage the VMCS to
avoid the VM-Entry consistency check.

Opportunistically update the wording of the comment to describe the
behavior as a workaround of flawed CPU behavior/architecture, to make it
clear that the *only* thing KVM is doing is fudging around a consistency
check.  Per the SDM:

  There are no pending debug exceptions after VM entry if any of the
  following are true:

    * The VM entry is vectoring with one of the following interruption
      types: external interrupt, non-maskable interrupt (NMI), hardware
      exception, or privileged software exception.

I.e. forcing GUEST_PENDING_DBG_EXCEPTIONS.BS does *not* impact guest-
visible behavior.

As all callers in inject_emulated_exception() use "struct x86_exception"
directly, capture it locally instead of using the context.

Subject: [PATCH 1476/5214] KVM: x86: Set guest DR6 by kvm_queue_exception_p()
 in instruction emulation

Record DR6 in emulate_db() and use kvm_queue_exception_p() to set DR6
instead of directly using kvm_set_dr6() in emulation, i.e. rely on the
standard exception path to set DR6 via kvm_deliver_exception_payload().
This keeps the handling of DR6 during #DB injection consistent with other
code paths.

No functional change intended.

 emulating MOV DR (in emulator)

When emulating a MOV DR instruction, honor KVM_GUESTDBG_USE_HW_BP when
checking DR7.GD, and if there is a general-detect #DB, route it to host
userspace as appropriate.  Consulting only the guest's actual DR7 causes
KVM to fail to report a DR access to userspace (assuming the guest itself
doesn't have DR7.GD=1).

Subject: [PATCH 1478/5214] KVM: x86: Honor KVM_GUESTDBG_USE_HW_BP when
 checking for code breakpoints in emulation

When KVM_GUESTDBG_USE_HW_BP is enabled, i.e. userspace is usurping the
guest's hardware debug registers, the guest's effective breakpoints are
controlled by userspace rather than by the guest itself.  Honor the
KVM_GUESTDBG_USE_HW_BP behavior when handling code #DBs in the emulator so
that userspace (and the guest) gets consistent behavior for code #DBs
regardless of whether an instruction is executed natively or emulated by
KVM.

To aid in userspace debug, don't treat code breakpoints as inhibited if
KVM_GUESTDBG_USE_HW_BP is enabled as accurately emulating x86 architecture
is obviously a non-goal of guest-debug.

Subject: [PATCH 1483/5214] KVM: selftests: Verify VMX's
 GUEST_PENDING_DBG_EXCEPTIONS.BS Consistency Check

In x86's debug_regs test, add a test case to cover the scenario where a
single-step #DB occurs in an STI-shadow, in which case KVM needs to stuff
vmcs.GUEST_PENDING_DBG_EXCEPTIONS.BS in order to satisfy a flawed VM-Entry
Consistency Check.

Wire up an IRQ handler to gain a bit of bonus coverage, as the subsequent
IRET from the #DB sets RFLAGS.IF, but *without* STI-blocking, and so the
pending IRQ is expected on the instruction immediately following STI.

Subject: [PATCH 1486/5214] seq_buf: Export seq_buf_putmem_hex() and add KUnit
 tests

The seq_buf KUnit suite does not exercise seq_buf_putmem_hex().

Add one test for the len > 8 chunking path and one overflow test
where a later chunk no longer fits in the buffer.

Export seq_buf_putmem_hex() as well so SEQ_BUF_KUNIT_TEST=m links
cleanly. Without the export, modpost reports seq_buf_putmem_hex as
undefined when seq_buf_kunit is built as a module.

Subject: [PATCH 1487/5214] tracing: Bound synthetic-field strings with seq_buf

The synthetic field helpers build a prefixed synthetic variable name and
a generated hist command in fixed MAX_FILTER_STR_VAL buffers. The
current code appends those strings with raw strcat(), so long key lists,
field names, or saved filters can run past the end of the staging
buffers.

Build both strings with seq_buf and propagate -E2BIG if either the
synthetic variable name or the generated command exceeds
MAX_FILTER_STR_VAL. This keeps the existing tracing-side limit while
using the helper intended for bounded command construction.

Subject: [PATCH 1488/5214] tracepoint: Add lockdep rcu_is_watching() check to
 trace_##name##_enabled()

The trace_##name##_enabled() static call branch is used when work needs to
be done for a tracepoint. It allows that work to be skipped when the
tracepoint is not active and still uses the static_branch() of the
tracepoint to keep performance.

Tracepoints themselves require being called in "RCU watching" locations
otherwise races can occur that corrupts things. In order to make sure
lockdep triggers at tracepoint locations, the lockdep checks are added to
the tracepoint calling location and trigger even if the tracepoint is not
enabled. This is done because a poorly placed tracepoint may never be
detected if it is never enabled when lockdep is enabled.

As trace_##name##_enabled() also prevents the lockdep checks when the
tracepoint is disabled add lockdep checks to that as well so that if one
is placed in a location that RCU is not watching, it will trigger a
lockdep splat even when the tracepoint is not enabled.

Subject: [PATCH 1489/5214] tracing: Remove local variable for argument
 detection from trace_printk()

The trace_printk() macro uses a local variable _______STR to detect
whether variadic arguments are present. This name can shadow outer
variables.

Replace the local variable with sizeof applied directly to the
stringified arguments:

  if (sizeof __stringify((__VA_ARGS__)) > 3)

This eliminates the shadowing risk entirely without introducing
any additional includes or local variables.

Verified with objdump on samples/trace_printk that all four cases
branch correctly: __trace_bputs, __trace_puts, __trace_bprintk,
and __trace_printk.

Subject: [PATCH 1492/5214] cpufreq: amd-pstate: Use trace_call__##name() at
 guarded tracepoint call site

Replace trace_foo() with the new trace_call__foo() at sites already
guarded by trace_foo_enabled(), avoiding a redundant
static_branch_unlikely() re-evaluation inside the tracepoint.
trace_call__foo() calls the tracepoint callbacks directly without
utilizing the static branch again.

Subject: [PATCH 1494/5214] tracing: Allow perf to read synthetic events

Currently, perf can not enable synthetic events. When it does, it either
causes a warning in the kernel or errors with "no such device".

Add the necessary code to allow perf to also attach to synthetic events.

Subject: [PATCH 1496/5214] tracing: Use krealloc_array() for trace option
 array growth

Use krealloc_array() when growing tr->topts instead of open-coding the
size calculation in krealloc().

This makes the resize path use the helper intended for array allocations
and avoids manual multiplication of the element count and element size.

trace_iterator_increment() is only called from trace_find_next_entry_inc().
It's a small enough function that really doesn't need to be separated.

Move the code from trace_iterator_increment() into
trace_find_next_entry_inc() and remove trace_iterator_increment().

Subject: [PATCH 1502/5214] f2fs: map data writes to FDP streams

From: Wenjie Qi <qiwenjie@xiaomi.com>

F2FS already classifies DATA writes using its existing hot, warm and cold
temperature policy, but it only passes that intent down as a write hint.
That hint alone is not sufficient for NVMe FDP placement, because the
current NVMe command path consumes `bio->bi_write_stream` rather than
`bio->bi_write_hint` when selecting a placement ID.

When the target block device exposes write streams, map the existing F2FS
DATA temperature classes onto stream IDs and set `bio->bi_write_stream`
for both buffered and direct writes. If the device exposes no write
streams, keep the current behavior by leaving the stream unset.

The stream mapping is evaluated against the target block device of each
bio, so the existing per-device fallback behavior stays unchanged for
multi-device filesystems. Existing blkzoned restrictions also remain in
place.

The mapping is intentionally small and deterministic:

- 1 stream: hot, warm and cold all use stream 1
- 2 streams: hot/warm use 1, cold uses 2
- 3+ streams: hot uses 1, warm uses 2, cold uses 3

This patch supports to report fserror, it provides another way to let
userspace to monitor filesystem level error. In addition, it exports
/sys/fs/f2fs/features/fserror once f2fs kernel module start to support
the new feature, then generic/791 of fstests can notice the feature,
and verify validation of fserror report.

Subject: [PATCH 1504/5214] f2fs: fix incorrect FI_NO_EXTENT handling in
 __destroy_extent_node()

When __destroy_extent_node() sets the inode flag FI_NO_EXTENT, it does
not reset the length of the largest extent to 0 and update the inode
folio. Since modifications to the extent tree are disallowed afterward,
the cached largest extent may become stale. This can trigger the
following error in xfstests generic/388:

F2FS-fs (dm-0): sanity_check_extent_cache: inode (ino=1761) extent info [220057, 57, 6] is incorrect, run fsck to fix

In the f2fs_drop_inode path, __destroy_extent_node() does not need to
guarantee that et->node_cnt is 0, because concurrency with writeback
is expected in this path, and writeback may update the extent cache.

This patch reverts commit ed78aeebef05 ("f2fs: fix node_cnt race between
extent node destroy and writeback"), and remove the unnecessary zero
check of et->node_cnt.

Fixes: ed78aeebef05 ("f2fs: fix node_cnt race between extent node destroy and writeback")

The root cause is a potential deadlock between the following tasks:

kworker/u8:11				Thread A
- f2fs_write_single_data_page
 - f2fs_do_write_data_page
  - folio_start_writeback(X)
  - f2fs_outplace_write_data
   - bio_add_folio(X)
 - folio_unlock(X)
					- truncate_inode_pages_range
					 - __filemap_get_folio(X, FGP_LOCK)
					 - truncate_inode_partial_folio(X)
					  - folio_wait_writeback(X)
 - f2fs_balance_fs
  - f2fs_gc
   - do_garbage_collect
    - move_data_page
     - f2fs_get_lock_data_page
      - __filemap_get_folio(X, FGP_LOCK)

Both threads try to access folio X. Thread A holds the lock but waits
for writeback, while kworker waits for the lock. This causes a deadlock.

Other threads also enter D state, waiting for locks such as gc_lock and
writepages.

OPU/IPU DATA folio are all affected by this issue. To avoid such
potential deadlocks, always commit these cached folios before
triggering f2fs_gc() in f2fs_balance_fs().

Subject: [PATCH 1507/5214] clk: renesas: rzg2l: Simplify SAM PLL configuration
 macro

Replace the PLL146_CONF() macro and its associated CPG_SAMPLL_CLK{1,2}(n)
helpers with a single CPG_SAM_PLL_CONF(stby) macro that takes the PLL
standby register offset directly.

This removes the implicit coupling between PLL index n and register layout
and eliminates the now-redundant GET_REG_SAMPLL_CLK2() macro. The RZ/V2M
PLL4 definition is also updated to use the new macro with its explicit
standby offset (0x100), removing the local PLL4_CONF define.

No functional changes.

Subject: [PATCH 1508/5214] clk: renesas: rzg3s/rzg3l: Simplify PLL
 configuration macro

Replace the per-SoC G3S_PLL146_CONF() and G3L_PLL1467_CONF() macros with
a unified CPG_PLL_CONF(stby, setting) macro defined in rzg2l-cpg.h.

Drop the now-redundant GET_REG_SAMPLL_{CLK1, SETTING}() macros, replacing
the latter with CPG_PLL1_SETTING_OFFSET() using FIELD_GET() to extract the
offset value. Update RZG3L_PLL_{STBY,MON}_OFFSET() macros to derive
offsets directly from CPG_PLL_STBY_OFFSET().

No functional changes.

Subject: [PATCH 1509/5214] clk: renesas: rzg2l: Rename RZG3L-prefixed PLL
 macros to CPG-prefixed ones

Rename RZG3L_PLL_STBY_OFFSET(), RZG3L_PLL_STBY_RESETB,
RZG3L_PLL_STBY_RESETB_WEN, RZG3L_PLL_MON_OFFSET(), RZG3L_PLL_MON_RESETB,
and RZG3L_PLL_MON_LOCK to their CPG_PLL_* equivalents to reflect that
these macros are not RZG3L-specific and are shared across SoCs.

Also fold CPG_PLL_MON_OFFSET() into rzg2l-cpg.c alongside the other
CPG_PLL_*_OFFSET() helpers introduced in previous patches.

No functional changes.

Subject: [PATCH 1510/5214] KVM: arm64: vgic-v5: Add for_each_visible_v5_ppi()
 iterator

We have multiple instances of iterators walking the vgic_ppi_mask
mask, and the way it is written has a tendency to make one's eyes
bleed.

Factor it as a helper and use that across the code base.

 kvm_vgic_global_state

Constant vgic properties are usually kept in kvm_vgic_global_state,
but the vgic-v5 code does its own thing.

Move the ppi_caps data into the global structure, which has the
modest additional advantage of making it ro_after_init.

Subject: [PATCH 1512/5214] KVM: arm64: vgic-v5: Remove use of __assign_bit()
 with a constant

Using __assign_bit() is very useful when the value of the bit is
not known at compile time. In all other cases, __set_bit() and
__clear_bit() are the correct tool for the job.

This also fixes an odd case of using VGIC_V5_NR_PRIVATE_IRQS as
the bit value...

Subject: [PATCH 1514/5214] KVM: arm64: vgic: Constify struct irq_ops usage

vgic-v5 has introduced much more prevalent usage of the struct
irq_ops mechanism.

In the process, it becomes evident that suffers from two related
problems:

- it contains flags, rather than only callbacks
- it is mutable, because we need to update the above flags

Swap the flags for a helper retrieving the flags, and make all
irq_ops const, something that is slightly satisfying.

 vgic_allocate_private_irqs_locked()

vgic_allocate_private_irqs_locked() calls two helpers, oddly named
vgic_{,v5_}allocate_private_irq().

Not only these helpers don't allocate anything, but they also
contain duplicate init code that would be better placed in the
caller.

Consolidate the common init code in the caller, rename the helpers
to vgic_{,v5_}setup_private_irq(), and pass the irq pointer around
instead of the index of the interrupt.

Subject: [PATCH 1516/5214] KVM: arm64: vgic-v5: Drop defensive checks from
 vgic_v5_ppi_queue_irq_unlock()

vgic_v5_ppi_queue_irq_unlock() performs a bunch of sanity checks
that are pretty pointless as there is no code path that can
result in these invariants to be violated. And if they are, a nice
crash is just as instructive than a warning.

Drop what is evidently debug code and simplify the whole thing.

Subject: [PATCH 1517/5214] KVM: arm64: vgic: Rationalise per-CPU irq accessor

Despite adding the necessary infrastructure to identify irq types,
vgic_get_vcpu_irq() treats GICv5 PPIs in a special way, which
impairs the readability of the code.

Use the existing irq classifiers to handle per-CPU irqs for all
vgic types, and let the normal control flow reach global interrupt
handling without any v5-specific path.

Subject: [PATCH 1518/5214] KVM: arm64: vgic-v5: Limit support to 64 PPIs

Although we have some code supporting 128 PPIs, the only supported
configuration is 64 PPIs. There is no way to test the 128 PPI code,
so it is bound to bitrot very quickly.

Given that KVM/arm64's goal has always been to stick to non-IMPDEF
behaviours, drop the 128 PPI support. Someone motivated enough and
with very strong arguments can always bring it back -- it's all in
the git history.

Subject: [PATCH 1520/5214] usb: chipidea: udc: support dynamic gadget
 add/remove

An asynchronous vbus_event_work() keep running when switch the role from
device to host. This affects EHCI host controller initialization.

USBCMD.RUNSTOP bit is set at ehci_run() and cleared by following
vbus_event_work() if bus_event_work() run after ehci_run().

The log below shows what happens:

[   87.819925] ci_hdrc ci_hdrc.0: EHCI Host Controller
[   87.819963] ci_hdrc ci_hdrc.0: new USB bus registered, assigned bus number 1
[   87.955634] ci_hdrc ci_hdrc.0: USB 2.0, controller refused to start: -110
[   87.955658] ci_hdrc ci_hdrc.0: startup error -110
[   87.955682] ci_hdrc ci_hdrc.0: USB bus 1 deregistered

The problem is that the chipidea UDC driver call usb_udc_vbus_handler() to
pull down data line but it don't wait for completion before host controller
starts running.

Now UDC core can properly delete usb gadget device and make sure that vbus
work is cancelled or completed after usb_del_gadget_udc() is returned. But
the udc.c only call usb_del_gadget_udc() in ci_hdrc_gadget_destroy(). To
avoid above issue, add/remove the gadget device dynamically during USB role
switching.

To support dynamic gadget add/remove, do below steps:
  - clear ci->gadget and ci->ci_hw_ep at initialization.
  - assign udc_[start|stop]() to rdrv->[start|stop] and properly merge the
    operations in udc_id_switch_for_[device|host]() to udc_[start|stop]()

Adjust the order ci_handle_vbus_change() and ci_role_start() to avoid NULL
pointer reference since ci_hdrc_gadget_init() doesn't add gadget anymore.

Subject: [PATCH 1521/5214] usb: core: hcd: fix possible deadlock in rh control
 transfers

>From within the SCSI error handler memory allocations must not
trigger IO. Handling errors in UAS and the storage driver may
involve resetting a device. The thread doing the reset itself
relies on VM magic. However, that is insufficient, as resetting
a device involves resuming it. Resumption as well as resetting
involves conrol transfers to the parent of the device to be reset.
That may be a root hub. Hence usbcore must heed the flags passed
to usb_submit_urb() processing control transfers to root hubs.

The problem exist since the storage driver has been merged.

Subject: [PATCH 1522/5214] usbip: vhci_hcd: fix NULL deref in status_show_vhci

platform_get_drvdata() can return NULL if a VHCI host controller's
probe failed (e.g. due to USB bus number exhaustion). status_show_vhci()
checked for a NULL pdev but not for a NULL hcd returned by
platform_get_drvdata(). Passing NULL to hcd_to_vhci_hcd() does not
return NULL - it returns a pointer offset of 0x260, causing a NULL
pointer dereference when that value is subsequently dereferenced.

Add a NULL check on hcd before calling hcd_to_vhci_hcd(). Move
status_show_not_ready() above status_show_vhci() to make it callable
from the new error path without a forward declaration.

Subject: [PATCH 1523/5214] usbip: vhci_hcd: reduce CONFIG_USBIP_VHCI_NR_HCS
 upper bound to 32

Each VHCI HC instance registers two USB buses (one HS, one SS).
USB_MAXBUS in drivers/usb/core/hcd.c is hard-coded to 64, giving an
effective maximum of 32 VHCI HC instances (32 * 2 = 64 buses).

The Kconfig range for USBIP_VHCI_NR_HCS currently allows up to 128,
which will cause probe failures for any HC instance beyond the 32nd.
These probe failures trigger the NULL pointer dereference fixed in the
previous commit.

Reduce the upper bound to 32 to reflect the real maximum imposed by
USB_MAXBUS. Note that probe failures can still occur below this limit
if real hardware has already claimed enough USB bus numbers, making
the NULL check fix necessary regardless.

Subject: [PATCH 1525/5214] usb: gadget: goku_udc: avoid NULL deref of
 dev->driver in INT_USBRESET log

goku_irq() handles a number of bus events under a single ep0 path.
It already guards the gadget driver suspend/resume callbacks against a
NULL ->driver:

	if (dev->gadget.speed != USB_SPEED_UNKNOWN
			&& dev->driver
			&& dev->driver->resume) {
		spin_unlock(&dev->lock);
		dev->driver->resume(&dev->gadget);
		...
	}

but the very next branch unconditionally dereferences dev->driver
when an INT_USBRESET arrives:

	if (stat & INT_USBRESET) {
		ACK(INT_USBRESET);
		INFO(dev, "USB reset done, gadget %s\n",
			dev->driver->driver.name);
	}

If the controller raises INT_USBRESET before any gadget driver has
been bound (or after one has been unbound), dev->driver is NULL and
the printk dereferences NULL.

smatch flags the inconsistency:

  drivers/usb/gadget/udc/goku_udc.c:1618 goku_irq() error:
  we previously assumed 'dev->driver' could be null (see line 1607)

Fall back to a placeholder when the gadget driver is not bound.

No functional change while a gadget driver is bound.

Subject: [PATCH 1527/5214] USB: cdc-acm: start bulk-IN polling when
 ALWAYS_POLL_CTRL is set

The INGENIC 17EF:6161 touchscreen composite device has a ~55-second
watchdog that resets the USB device if the bulk-IN endpoint on the CDC
data interface goes unread.  The existing ALWAYS_POLL_CTRL quirk keeps
the notification endpoint (ctrlurb / EP 0x82) polling continuously, but
that alone is insufficient: the firmware monitors bulk-IN activity, not
just notification-endpoint activity.

Add acm_submit_read_urbs() calls to the two ALWAYS_POLL_CTRL paths that
already restart the ctrlurb:

  1. acm_probe(): start bulk reads at probe time alongside the ctrlurb,
     so the watchdog is satisfied from first bind without requiring a
     userspace process to open /dev/ttyACMn.

  2. acm_port_shutdown(): restart bulk reads after port close alongside
     the ctrlurb restart, so the watchdog keeps running when the last
     TTY user closes the port.

acm_read_bulk_callback() already resubmits each URB unconditionally on
normal completion, so once submitted the reads remain active until an
explicit kill (disconnect, suspend).  acm_submit_read_urb() is a no-op
for URBs that are already in flight (read_urbs_free bit clear), so the
existing acm_port_activate() call remains correct and races are avoided.

Tested on Lenovo Yoga Book 9 14IAH10 (83KJ): without this patch the
device resets every ~55 s when no TTY is open; with it the device
remains stable indefinitely.

Subject: [PATCH 1528/5214] dt-bindings: usb: ci-hdrc-usb2: allow up to 3
 clocks for qcom,ci-hdrc

Some Qualcomm SoCs such as apq8064 and msm8960 require a third "fs"
clock in addition to "iface" and "core", needed to propagate resets
through the controller and wrapper logic. Later SoCs such as msm8974
dropped this requirement and only use two clocks.

Note that the existing apq8064 and msm8960 DTS files currently specify
the "iface" and "core" clocks in reverse order compared to most newer
SoCs DTS, which causes dtbs_check warnings for these older SoCs. The
dependent patch series will fix that clock ordering.

The problem is that all connector locks belong to the same
lockdep lock class, so the following loop:

	for (i = 0; i < ucsi->cap.num_connectors; i++)
		ucsi_register_port(connector[i])
			mutex_lock(&connector[i]->lock)

looks like a recursive acquire of the same mutex.  Put each connector
lock into a dedicated lock class so that lockdep doesn't see it as a
possible recursion.

Subject: [PATCH 1530/5214] usb: host: max3421: Fix shift-out-of-bounds in
 max3421_hub_control()

The `max3421_hub_control()` function handles USB hub class requests
to the virtual root hub. In the `default` branches of both the
`ClearPortFeature` and `SetPortFeature` switch statements, it modifies
`max3421_hcd->port_status` by left shifting 1 by the request's `value`
parameter. However, it does not validate whether this shift will exceed
the width of `port_status`.

So if a malicious userspace task with access to the root hub via
/dev/bus/usb/.../001 issues a USBDEVFS_CONTROL ioctl with `wValue`
greater than or equal to 32, the left shift operation invokes
shift-out-of-bounds undefined behavior. This results in arbitrary
bit corruption of `port_status`, including the normally-immutable
change bits, which can bypass internal state checks and confuse the
hub status.

Fix this by rejecting requests whose `value` exceeds the shift width
before performing the shift.

This issue was found using a KLEE-based symbolic execution tool for
kernel drivers that I'm currently developing.

The `max3421_hub_control()` function handles USB hub class requests
to the virtual root hub. The `GetPortStatus` case correctly rejects
requests with `index != 1`, since the virtual root hub has only a
single port. However, the `ClearPortFeature` and `SetPortFeature`

Fix this by extending the `index != 1` rejection to both cases,
matching the existing behavior of `GetPortStatus`.

connector ports - the port going to the USB controller.

The driver does not use the "port" property and there is no upstream DTS
which would have it.  It looks like it's left-over of early versions of
this patchset and is completely redundant now, so let's drop it.

Subject: [PATCH 1533/5214] USB: typec: qcom-pmic-typec: Drop redundant header
 includes

Unlike other units in this module, this one does not request interrupts
or regulator supplies.  It does not use OF graph, USB role switching or
TypeC muxing APIs.  Drop redundant header includes to speed up
preprocessor.

Subject: [PATCH 1534/5214] dt-bindings: usb: qcom,pmic-typec: deprecate
 device-specific VBUS

The Qualcomm PMIC Type-C devices historically provided their own way of
specifying the VBUS regulator, via the device's vdd-vbus-supply node.
This is not ideal as the VBUS is supplied to the connector and not to
the Type-C block in the PMIC. Deprecate this property in favour of the
standard way of specifying it (via the connector's vbus-supply
property).

Subject: [PATCH 1535/5214] usb: typec: tcpm: qcom: prefer VBUS supply from the
 connector node

Current way of specifying VBUS supply (via the device's vdd-vbus-supply
property) is not ideal. In the end, VBUS is supplied to the USB-C
connector rather than the Type-C block in the PMIC. Follow the standard
way of specifying it (via the connector node) and fallback to the old
property if there is no vbus-supply in the connector node.

Subject: [PATCH 1540/5214] usb: host: add ARCH_AIROHA in XHCI MTK dependency

Airoha SoC use the same register map and logic of the Mediatek xHCI
driver, hence add it to the dependency list to permit compilation also
on this ARCH.

Subject: [PATCH 1541/5214] usb: typec: ucsi: Add support for message_out data
 structure

Add support for UCSI message_out data structure. The UCSI
interface defines separate message_in and message_out data
structure for bidirectional communication, where commands
like Set PDOs and LPM Firmware Update require writing data
to message_out before command execution.

Add write_message_out operation to ucsi_operations structure
to allow platform drivers to implement message_out data writing
capability.

Update ucsi_sync_control_common to accept message_out parameters
and call write_message_out followed by command execution to
maintain proper sequencing as per the UCSI specification.

Introduce ucsi_write_message_out_command for commands that need
to send message_out data, while maintaining ucsi_send_command
for commands that only require message_in response data.

Subject: [PATCH 1542/5214] usb: typec: ucsi: Enable debugfs for message_out
 data structure

Add debugfs entry for writing message_out data structure to handle
UCSI 2.1 and 3.0 commands through debugfs interface.

Users writing to the message_out debugfs file should ensure the input
data adheres to the following format:
1. Input must be a non-empty valid hexadecimal string.
2. Input length of hexadecimal string must not exceed 256 bytes of
   length to be in alignment with the message out data structure size
   as per the UCSI specification v2.1.
3. If the input string length is odd, then user needs to prepend a
   '0' to the first character for proper hex conversion.

Below are examples of valid hex strings. Note that these values are
just examples. The exact values depend on specific command use case.

        #echo 1A2B3C4D > message_out
        #echo 01234567 > message_out

Subject: [PATCH 1544/5214] usb: dwc2: remove WARN in dwc2_hcd_save_data_toggle

The WARN() in dwc2_hcd_save_data_toggle() was introduced in
commit 62943b7dfa35 ("usb: dwc2: host: fix the data toggle error in
full speed descriptor dma"), it looks like the WARN() is to ensure
proper usage of dwc2_hcd_save_data_toggle(): either qtd is provided
for control eps or qh is provided for non-control eps. This check is
good even if there's no such improper usage in current code. But the
WARN() usage in driver is discouraged nowadays: imagine there is an
improper usage, then kernel panic due to warn if 'panic_on_warn' is
enabled.

While emitting the err msg for improper usage is still valueable, so
let's replace the WARN with check and dev_err().

At the same time, it looks a bit strange we check !chan after
dereference of this pointer with
"if (chan->ep_type != USB_ENDPOINT_XFER_CONTROL)".

In fact, when entering the dwc2_hcd_save_data_toggle(), the chan won't
be NULL, because its caller or indirect caller has ensured this,
specifically, it's checked with below line in dwc2_hc_n_intr()

if (!chan) {
    dev_err(hsotg->dev, "## hc_ptr_array for channel is NULL ##\n");
    return;
}

This addresses the following issue reported by klocwork tool:
  - Suspicious dereference of pointer 'chan' before NULL check at
    line 518

Subject: [PATCH 1545/5214] usb: gadget: aspeed_udc: avoid past-the-end
 iterator in dequeue

ast_udc_ep_dequeue() declares the loop cursor `req` outside the
list_for_each_entry(). After the loop it tests `&req->req != _req`
to decide whether the request was found. If the queue holds no
match, `req` is past-the-end. It then aliases
container_of(&ep->queue, struct ast_udc_request, queue) via offset
cancellation. Whether that synthetic address equals `_req` depends
on heap layout. The function can return 0 without dequeueing
anything.

Default `rc` to -EINVAL and set it to 0 only inside the match
branch. `req` is no longer read after the loop, so the past-the-end
dereference goes away. No extra cursor variable or post-loop test
is needed.

Subject: [PATCH 1546/5214] dt-bindings: usb: cdns3: Add cdns,cdnsp compatible
 string

Introduce a new generic fallback compatible string 'cdns,cdnsp' for
Cadence USBSSP controllers to support hardware configurations where
the Dual-Role Device (DRD) register block is missing or inaccessible.

Following the maintainer's feedback, avoid generic property-like naming
(such as "-no-drd") and use a clean generic fallback. To keep the schema
resource-driven and strictly validated, define a two-string compatible
matrix using an empty schema ({}) wildcard. This allows future vendor
SoC compatibles to be prepended while safely falling back to the 2-resource
USBSSP configuration.

When 'cdns,cdnsp' is matched:
- The 'otg' register and interrupt resources are not required.
- The 'reg' and 'interrupts' properties are restricted to 2 items
  (host and device).
- 'dr_mode' must be explicitly set to either 'host' or 'peripheral'.

The standard 'cdns,usb3' compatible remains unchanged, maintaining
backward compatibility by requiring all 3 resource sets (otg, host, dev).

Subject: [PATCH 1547/5214] usb: cdnsp: Add support for device-only
 configuration

This patch introduces support for the Cadence USBSSP (cdnsp)
controller in hardware configurations where the Dual-Role Device (DRD)
register block is not implemented or is inaccessible.

In such cases, the driver cannot rely on the DRD logic to manage roles
and must operate exclusively in a fixed peripheral/host mode.

The change in BAR indexing (from BAR 2 to BAR 1) is a direct
consequence of the 32-bit addressing used in this specific
DRD-disabled hardware layout, compared to the 64-bit addressing
used in DRD-enabled configurations.

Tested on a PCI platform with a hardware configuration that lacks
DRD support. Platform-side changes are included to support the PCI
glue layer's property injection to handle this specific layout.

Subject: [PATCH 1548/5214] serial: max310x: fix compile errors if
 CONFIG_SPI_MASTER is disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since commit 20ffe4b3330a8 ("serial: max310x: allow driver to be built with
SPI or I2C"), if I2C is enabled and SPI_MASTER is disabled, we have these
compile errors:

  drivers/tty/serial/max310x.c: In function 'max310x_uart_init':
  drivers/tty/serial/max310x.c: error: 'max310x_spi_driver' undeclared...
  drivers/tty/serial/max310x.c: In function ‘max310x_uart_init’:
  drivers/tty/serial/max310x.c: error: label ‘err_spi_register’
  defined but not used...
  drivers/tty/serial/max310x.c: error: ‘regcfg’ defined but not used

Fix by properly encapsulating i2c/spi code/variables in their respective
context with IS_ENABLED() macros for CONFIG_I2C and CONFIG_SPI_MASTER.

Also fix link failure with SERIAL_MAX310X=y and I2C=m by modifying Kconfig
depends.

Fixes: 20ffe4b3330a8 ("serial: max310x: allow driver to be built with SPI or I2C")

Subject: [PATCH 1551/5214] tty: serial: 8250: protect against NULL
 uart->port.dev in register

serial8250_register_8250_port() conditionally copies uart->port.dev
from up->port.dev only when up->port.dev is non-NULL:

	if (up->port.dev) {
		uart->port.dev = up->port.dev;
		...
	}

So if both the existing uart slot and up have a NULL ->dev,
uart->port.dev remains NULL. The very next ACPI companion check
then dereferences it unconditionally:

	if (!has_acpi_companion(uart->port.dev)) {

has_acpi_companion() reads dev->fwnode without a NULL guard
(include/linux/acpi.h), so this NULL-derefs the kernel for the
remaining no-dev case rather than just skipping the
mctrl_gpio_init() initialisation as intended.

smatch flags the inconsistency:

  drivers/tty/serial/8250/8250_core.c:767
  serial8250_register_8250_port() error: 'uart->port.dev' could be
  null (see line 719)

Guard the call with a NULL check so register continues to work
for callers that legitimately have no parent device (legacy
non-OF/non-ACPI registrations).

No functional change for callers that pass a non-NULL ->dev.

Subject: [PATCH 1553/5214] serial: 8250: Check LSR timeout on console flow
 control

wait_for_xmitr() calls wait_for_lsr() to wait for the transmission
registers to be empty. wait_for_lsr() can timeout after a reasonable
amount of time.

When console flow control is active, wait_for_xmitr() additionally
polls CTS, waiting for the peer to signal that it is ready to receive
more data.

If hardware flow control is enabled (auto CTS) and the peer deasserts
CTS, wait_for_lsr() will timeout. If additionally console flow
control is active and while polling CTS the peer asserts CTS, the
console will assume it can immediately transmit, even though the
transmission registers may not be empty. This can lead to data loss.

Avoid this problem by performing an extra wait_for_lsr() upon CTS
assertion if wait_for_lsr() previously timed out.

Subject: [PATCH 1554/5214] serial: 8250: Add support for console flow control

The kernel documentation specifies that the console option 'r' can
be used to enable hardware flow control for console writes. The 8250
driver does include code for hardware flow control on the console if
cons_flow is set, but there is no code path that actually sets this.
However, that is not the only issue. The problems are:

1. Specifying the console option 'r' does not lead to cons_flow being
   set.

2. Even if cons_flow would be set, serial8250_register_8250_port()
   clears it.

3. When the console option 'r' is specified, uart_set_options()
   attempts to initialize the port for CRTSCTS. However, afterwards
   it does not set the UPSTAT_CTS_ENABLE status bit and therefore on
   boot, uart_cts_enabled() is always false. This policy bit is
   important for console drivers as a criteria if they may poll CTS.

4. Even though uart_set_options() attempts to initialize the port
   for CRTSCTS, the 8250 set_termios() callback does not enable the
   RTS signal (TIOCM_RTS) and thus the hardware is not properly
   initialized for CTS polling.

5. Even if modem control was properly setup for CTS polling
   (TIOCM_RTS), uart_configure_port() clears TIOCM_RTS, thus
   breaking CTS polling.

6. wait_for_xmitr() and serial8250_console_write() use cons_flow
   to decide if CTS polling should occur. However, the condition
   should also include a check that it is not in RS485 mode and
   CRTSCTS is actually enabled in the hardware.

Address all these issues as conservatively as possible by gating them
behind checks focussed on the user specifying console hardware flow
control support and the hardware being configured for CTS polling
at the time of the write to the UART.

Since checking the UPSTAT_CTS_ENABLE status bit is a part of the new
condition gate, these changes also support runtime termios updates to
disable/enable CRTSCTS.

dw8250_probe() registers the 8250 port via serial8250_register_8250_port()
and then, if the device has a clock, registers a clock notifier. If
clk_notifier_register() fails, probe returns the error but leaves the
8250 port registered. The matching serial8250_unregister_port() lives
in dw8250_remove(), which is not called when probe fails, so the port
slot stays occupied until the device is rebound or the system is
rebooted. The devm-allocated driver data is freed while the port still
references it (via the saved private_data and serial_in/serial_out
callbacks), so any access to that port slot before a rebind is a
use-after-free hazard.

Unregister the port on the clk_notifier_register() error path.

Subject: [PATCH 1557/5214] serial: 8250_dw: remove clock-notifier
 infrastructure

The clock notifier and matching work_struct in dw8250_data were added
in 2020 for the Baikal-T1 SoC, whose multiple UART ports share a
single reference clock and need to be informed when another consumer
re-rates that clock.

Baikal SoC support has since been removed from the kernel (see e.g.
commit 5d6c477687ae ("clk: baikal-t1: Remove not-going-to-be-supported
code for Baikal SoC") and the matching removals across bus/, mtd/,
PCI/, hwmon/, memory/). No remaining in-tree user needs the
cross-device baudclk rate-change notification path: the only
configuration that wired up the notifier was Baikal-T1's shared
reference clock topology.

Drop the now-unused clock-notifier and its deferred-update worker:

  - struct dw8250_data fields clk_notifier and clk_work,
  - the clk_to_dw8250_data() and work_to_dw8250_data() helpers,
  - the dw8250_clk_work_cb() and dw8250_clk_notifier_cb() callbacks,
  - the INIT_WORK / notifier_call setup in dw8250_probe(),
  - the clk_notifier_register() / queue_work() in dw8250_probe(),
  - the matching clk_notifier_unregister() / flush_work() in
    dw8250_remove(),
  - the stale comment in dw8250_set_termios() about the worker
    blocking,
  - the linux/notifier.h and linux/workqueue.h includes that are
    no longer used.

dw8250_set_termios() keeps calling clk_set_rate() directly, which is
all the remaining single-UART configurations require.

Subject: [PATCH 1558/5214] tty: serial: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace in the list
terminator.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 1560/5214] dt-bindings: serial: rs485: remove deprecated .txt
 binding stub

The plain text binding file was superseded by the YAML schema in
commit d50f974c4f7f ("dt-bindings: serial: Convert rs485 bindings
to json-schema"). The file now contains only a redirect notice.
Remove it, and update references in serial_core.c and
serial-rs485.rst to point to the YAML schema.

Subject: [PATCH 1561/5214] serial: 8250: fix possible ISR soft lockup

There are rare cases in which the host gets stuck in the ISR because it
is flooded with messages during the startup phase.

The reason for the soft lockup in the ISR is the missing FIFO error IRQ
(FIFOE) handling. Not handling it and reporting IRQ_HANDLED triggers
the IRQ immediately again.

Fix this by adding a check for the FIFOE status and clearing the FIFO
if no data is ready (DR).

This behavior was observed on an AM62L device which uses the OMAP 8250
driver. Fix it for all 8250 drivers, since the OMAP driver's special
IRQ setup handling may trigger this behavior more frequently, but it
is not ensured that other 8250 drivers aren't affected.

Subject: [PATCH 1562/5214] vt: merge ucs_is_zero_width()/ucs_is_double_width()
 into ucs_get_width()

The hot path in vc_process_ucs() asks two independent questions about the
same code point -- "is it double-width?" and "is it zero-width?" -- and
was answering each with its own bsearch over its own table. For anything
past the leading bounds check that meant two scans of the BMP width
tables back to back for what is logically a single lookup.

Replace both with one ucs_get_width(cp) returning 0, 1, or 2 in a single
bsearch, while keeping the total table footprint at the same 2384 B as
before.

To do so, merge the zero-width and double-width ranges per region into
one sorted-by-`first` table. BMP entries stay 4 bytes; per-entry width
is hosted in spare bits of the non-BMP table's `last` field. Non-BMP
code points use only 20 of 32 bits, so each u32 has 12 unused high bits.
Store first/last shifted left by 12 and use the low 12 bits of `last`
for metadata: bit 11 is this entry's own width flag, bits 0..7 host an
8-bit chunk of the BMP double-width bitmap. Because the metadata bits
sit strictly below the lowest cp-scale bit, the bsearch comparator
remains a plain u32 compare on shifted keys with no masking.

In vc_process_ucs() the overwhelmingly common single-width path now
collapses to a single predicted branch:

	if (likely(w == 1))
		return 1;

Note: scripts/checkpatch.pl complains about "Macros with complex values
      should be enclosed in parentheses" for the BMP_*WIDTH and
      RANGE_*WIDTH macros. They are deliberately defined to expand to a
      comma-separated (first, last) pair so they can populate the two
      adjacent fields of a struct initializer; wrapping them in
      parentheses would turn that into a comma-expression and defeat
      the whole construction. Please ignore.

+KernelSbom
+==========
+
+Introduction
+------------
+
+KernelSbom is a Python script ``scripts/sbom/sbom.py`` that can be
+executed after a successful kernel build. When invoked, KernelSbom
+analyzes all files involved in the build and generates Software Bill of
+Materials (SBOM) documents in SPDX 3.0.1 format.
+The generated SBOM documents capture:
+
+* **Final output artifacts**, typically the kernel image and modules
+* **All source files** that contributed to the build with metadata
+  and licensing information
+* **Details of the build process**, including intermediate artifacts
+  and the build commands linking source files to the final output
+  artifacts
+
+KernelSbom is originally developed in the
+`KernelSbom repository <https://github.com/TNG/KernelSbom>`_.
+
+Requirements
+------------
+
+Python 3.10 or later. No libraries or other dependencies are required.
+
+Basic Usage
+-----------
+
+Run the ``make sbom`` target.
+For example::
+
+    $ make defconfig O=kernel_build
+    $ make sbom O=kernel_build -j$(nproc)
+
+This will trigger a kernel build. After all build outputs have been
+generated, KernelSbom produces three SPDX documents in the root
+directory of the object tree:
+
+* ``sbom-source.spdx.json``
+  Describes all source files involved in the build and
+  associates each file with its corresponding license expression.
+
+* ``sbom-output.spdx.json``
+  Captures all final build outputs (kernel image and ``.ko`` module files)
+  and includes build metadata such as environment variables and
+  a hash of the ``.config`` file used for the build.
+
+* ``sbom-build.spdx.json``
+  Imports files from the source and output documents and describes every
+  intermediate build artifact. For each artifact, it records the exact
+  build command used and establishes the relationship between
+  input files and generated outputs.
+
+When invoking the sbom target, it is recommended to perform
+out-of-tree builds using ``O=<objtree>``. KernelSbom classifies files as
+source files when they are located in the source tree and not in the
+object tree. For in-tree builds, where the source and object trees are
+the same directory, this distinction can no longer be made reliably.
+In that case, KernelSbom does not generate a dedicated source SBOM.
+Instead, source files are included in the build SBOM.
+
+Standalone Usage
+----------------
+
+KernelSbom can also be used as a standalone script to generate
+SPDX documents for specific build outputs. For example, after a
+successful x86 kernel build, KernelSbom can generate SPDX documents
+for the ``bzImage`` kernel image::
+
+    $ SRCARCH=x86 python3 scripts/sbom/sbom.py \
+        --src-tree . \
+        --obj-tree ./kernel_build \
+        --roots arch/x86/boot/bzImage \
+        --generate-spdx \
+        --generate-used-files \
+        --prettify-json \
+        --debug
+
+Note that when KernelSbom is invoked outside of the ``make`` process,
+the environment variables used during compilation are not available and
+therefore cannot be included in the generated SPDX documents. It is
+recommended to set at least the ``SRCARCH`` environment variable to the
+architecture for which the build was performed.
+
+For a full list of command-line options, run::
+
+    $ python3 scripts/sbom/sbom.py --help
+
+Output Format
+-------------
+
+KernelSbom generates documents conforming to the
+`SPDX 3.0.1 specification <https://spdx.github.io/spdx-spec/v3.0.1/>`_
+serialized as JSON-LD.
+
+To reduce file size, the output documents use the JSON-LD ``@context``
+to define custom prefixes for ``spdxId`` values. While this is compliant
+with the SPDX specification, only a limited number of tools in the
+current SPDX ecosystem support custom JSON-LD contexts. To use such
+tools with the generated documents, the custom JSON-LD context must
+be expanded before providing the documents.
+See https://lists.spdx.org/g/Spdx-tech/message/6064 for more information.
+
+How it Works
+------------
+
+KernelSbom operates in two major phases:
+
+1. **Generate the cmd graph**, an acyclic directed dependency graph.
+2. **Generate SPDX documents** based on the cmd graph.
+
+KernelSbom begins from the root artifacts specified by the user, e.g.,
+``arch/x86/boot/bzImage``. For each root artifact, it collects all
+dependencies required to build that artifact. The dependencies come
+from multiple sources:
+
+* **.cmd files**: The primary source is the ``.cmd`` file of the
+  generated artifact, e.g., ``arch/x86/boot/.bzImage.cmd``. These files
+  contain the exact command used to build the artifact and often include
+  an explicit list of input dependencies. By parsing the ``.cmd``
+  file, the full list of dependencies can be obtained.
+
+* **.incbin statements**: The second source are include binary
+  ``.incbin`` statements in ``.S`` assembly files.
+
+* **Hardcoded dependencies**: Unfortunately, not all build dependencies
+  can be found via ``.cmd`` files and ``.incbin`` statements. Some build
+  dependencies are directly defined in Makefiles or Kbuild files.
+  Parsing these files is considered too complex for the scope of this
+  project. Instead, the remaining gaps of the graph are filled using a
+  list of manually defined dependencies, see
+  ``scripts/sbom/sbom/cmd_graph/hardcoded_dependencies.py``. This list is
+  known to be incomplete. However, analysis of the cmd graph indicates a
+  ~99% completeness. For more information about the completeness analysis,
+  see `KernelSbom #95 <https://github.com/TNG/KernelSbom/issues/95>`_.
+
+Given the list of dependency files, KernelSbom recursively processes
+each file, expanding the dependency chain all the way to the version
+controlled source files. The result is a complete dependency graph
+where nodes represent files, and edges represent "file A was used to
+build file B" relationships.
+
+Using the cmd graph, KernelSbom produces three SPDX documents.
+For every file in the graph, KernelSbom:
+
+* Parses ``SPDX-License-Identifier`` headers,
+* Computes file hashes,
+* Estimates the file type based on extension and path,
+* Records build relationships between files.
+
+Each root output file is additionally associated with an SPDX Package
+element that captures version information, license data, and copyright.
+
+Advanced Usage
+--------------
+
+Including Kernel Modules
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The list of all ``.ko`` kernel modules produced during a build can be
+extracted from the ``modules.order`` file within the object tree.
+For example::
+
+    $ echo "arch/x86/boot/bzImage" > sbom-roots.txt
+    $ sed 's/\.o$/.ko/' ./kernel_build/modules.order >> sbom-roots.txt
+
+Then use the generated roots file::
+
+    $ SRCARCH=x86 python3 scripts/sbom/sbom.py \
+        --src-tree . \
+        --obj-tree ./kernel_build \
+        --roots-file sbom-roots.txt \
+        --generate-spdx
+
+Equal Source and Object Trees
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When the source tree and object tree are identical (for example, when
+building in-tree), source files can no longer be reliably distinguished
+from generated files.
+In this scenario, KernelSbom does not produce a dedicated
+``sbom-source.spdx.json`` document. Instead, both source files and build
+artifacts are included together in ``sbom-build.spdx.json``, and
+``sbom.used-files.txt`` lists all files referenced in the build document.
+
+Unknown Build Commands
+~~~~~~~~~~~~~~~~~~~~~~
+
+Because the kernel supports a wide range of configurations and versions,
+KernelSbom may encounter build commands in ``.cmd`` files that it does
+not yet support. By default, KernelSbom will fail if an unknown build
+command is encountered.
+
+If you still wish to generate SPDX documents despite unsupported
+commands, you can use the ``--do-not-fail-on-unknown-build-command``
+option. KernelSbom will continue and produce the documents, although
+the resulting SBOM will be incomplete.
+
+This option should only be used when the missing portion of the
+dependency graph is small and an incomplete SBOM is acceptable for
+your use case.

Subject: [PATCH 1567/5214] scripts/sbom: add cmd graph generation

Implement command graph generation by parsing .cmd files to build a
dependency graph.
Add CmdGraph, CmdGraphNode, and .cmd file parsing.
Supports generating a flat list of used source files via the
--generate-used-files cli argument.

Subject: [PATCH 1570/5214] scripts/sbom: add JSON-LD serialization

Add infrastructure to serialize an SPDX graph as a JSON-LD
document. NamespaceMaps in the SPDX document are converted
to custom prefixes in the @context field of the JSON-LD output.

The SBOM tool uses NamespaceMaps solely to shorten SPDX IDs,
avoiding repetition of full namespace URIs by using short prefixes.

Implement the kernel_file module that collects file metadata,
including license identifier for source files, SHA-256 hash,
Git blob object ID, an estimation of the file type, and
whether files belong to the source, build, or output SBOM.

Subject: [PATCH 1578/5214] KVM: selftests: Fix vcpu_get_stats_fd() ioctl name

vcpu_get_stats_fd() invokes KVM_GET_STATS_FD, but its assertion reports
KVM_CHECK_EXTENSION if the ioctl fails.  Use KVM_GET_STATS_FD in the
assertion so failures point at the ioctl that actually failed.

Fixes: 1b78d474ce4e ("KVM: selftests: Add logic to detect if ioctl() failed because VM was killed")

Subject: [PATCH 1580/5214] clk: canaan: Add clock driver for Canaan K230

This patch provides basic support for the K230 clock, which covers
all clocks in K230 SoC.

The clock tree of the K230 SoC consists of a 24MHZ external crystal
oscillator, PLLs and an external pulse input for timerX, and their
derived clocks.

Subject: [PATCH 1581/5214] perf stat: Make metric only column line up with
 header

Since some time the metric-only output columns are messed up and do not
line up with the header, which makes it hard to read. I haven't bisected
it, but presumably it was broken for some time.

There were multiple problems:
- The dummy pm invocation at the beginning did print a bogus field
- The column computation in pm did not agree with the header length
- The color escape strings from highlighting confuse printf's field
  length computation

Fix all those. I simplified the column width computation significantly,
ignoring EVNAME_LEN, MGROUP_LEN, config->unit_width which don't
seem to be useful in the metric only context. It now only uses
the actual unit width as well as config->metric_only_len. The result
is more code removed than added.

Before:

% perf stat --topdown -a -I 1000
+           time %  tma_backend_bound %  tma_frontend_bound %  tma_bad_speculation      %  tma_retiring

     2.005185654                                         45.3                   40.1                     5.6                     9.0
     3.009193207                                         45.4                   39.9                     5.6                     9.1

After:

Subject: [PATCH 1582/5214] KVM: x86: Add dedicated API for getting mask of
 accelerated x2APIC MSRs

Add a dedicated local APIC API, kvm_x2apic_disable_intercept_reg_mask(),
to provide the mask of x2APIC registers whose MSRs can and should be passed
through to the guest when x2APIC virtualization is enable, and use it in
lieu of the open-coded equivalent VMX logic.  Providing a common helper
will allow sharing the logic with SVM (x2AVIC), and as a bonus eliminates
the somewhat confusing code where KVM enables interception for MSR_TYPE_RW,
even though only the READ case actually needs to be updated.

No functional change intended.

Subject: [PATCH 1583/5214] KVM: SVM: Disable x2AVIC RDMSR interception for
 MSRs KVM actually supports

When toggling x2AVIC on/off, use KVM's curated mask of x2APIC MSRs that
can/should be passed through to the guest (or not) when 2AVIC is enabled.
Using the effective list provided by the local APIC emulation fixes
multiple (classes of) bugs, as the existing hand-coded list of MSRs is
wrong on multiple fronts:

 - ARBPRI isn't supported by KVM, isn't accelerated by AVIC (for read or
   write), and its #VMEXIT is fault-like, i.e. requires decoding the
   instruction.  Disabling interception is nonsensical and suboptimal.

 - DFR and ICR2 aren't supported by x2APIC and so don't need their
   intercepts disabled for performance reasons.  While the #GP due to
   x2APIC being abled has higher priority than the trap-like #VMEXIT,
   disabling interception of unsupported MSRs is confusing and unnecessary.

 - RRR is completely unsupported.

 - AVIC currently fails to pass through the "range of vectors" registers,
   IRR, ISR, and TMR, as e.g. X2APIC_MSR(APIC_IRR) only affects IRR0, and
   thus only disables intercept for vectors 31:0 (which are the *least*
   interesting registers).

 - TMCCT (the current APIC timer count) isn't accelerated by hardware, and
   generates a fault-like AVIC_UNACCELERATED_ACCESS #VMEXIT, i.e. requires
   KVM to decode the instruction to figure out what the guest was trying to
   access.  Note, the only reason this isn't a fatal bug is that the AVIC
   architecture had the foresight to guard against buggy hypervisors.  E.g.
   if hardware simply read from the virtual APIC page, the guest would get
   garbage (because the timer is emulated in software).

Subject: [PATCH 1584/5214] KVM: SVM: Only disable x2AVIC WRMSR interception
 for MSRs that are accelerated

When x2AVIC is enabled, disable WRMSR interception only for MSRs that are
actually accelerated by hardware.  Disabling interception for MSRs that
aren't accelerated is functionally "fine", and in some cases a weird "win"
for performance, but only for cases that should never be triggered by a
well-behaved VM (writes to read-only registers; the #GP will typically
occur in the guest without taking a #VMEXIT, even for fault-like exits).

But overall, disabling interception for MSRs that aren't accelerated is at
best confusing and unintuitive, and at worst introduces avoidable risk, as
the APM's documentation is imperfect and contradictory.  The table in
"15.29.3.1 Virtual APIC Register Accesses" of simply states that such
writes generate exits, where as "Section 15.29.10 x2AVIC" says:

  x2APIC MSR intercept checks and access checks have higher priority than
  AVIC access permission checks.

CPU behavior follows the latter (which makes perfect sense), but all in
all there's simply no reason to disable interception just to make a #GP
faster.

Note, the set of MSRs that are passed through for write is identical to
VMX's set when IPI virtualization is enabled.  This is not a coincidence,
and is another motiviating factor for cleaning up the intercepts, as x2AVIC
is functionally equivalent to APICv+IPIv.

Subject: [PATCH 1585/5214] perf build: Unconditionally set up libunwind
 feature build flags

A "make feature-dump" build does not specify LIBUNWIND=1 because it is
run with the default configuration to detect system-wide capabilities.
This sets NO_LIBUNWIND := 1, causing Makefile.config to skip setting
LIBUNWIND_LIBS and FEATURE_CHECK_LDFLAGS-libunwind.

Consequently, when Makefile.feature is included and attempts to run
all feature checks (via FEATURE_TESTS := all), the local feature test
test-libunwind.bin compiles without the required architecture-specific
library flags (-lunwind-x86_64) and fails to link on x86_64. This
results in a corrupted cached BUILD_TEST_FEATURE_DUMP showing
feature-libunwind=0 even when the host supports it.

Subsequent test builds (like make_libunwind_O in the build-test suite)
which reuse the feature dump and specify LIBUNWIND=1 will fail to
compile due to a mismatch where CONFIG_LIBUNWIND is set (via remote
architecture checks which are self-contained) but HAVE_LIBUNWIND_SUPPORT
is disabled, causing compiler errors due to missing maps__e_machine
definitions in maps.h.

Fix this by unconditionally setting up the libunwind library lists
and feature check LDFLAGS in Makefile.config so they are always
populated and available to the feature detection engine regardless
of whether LIBUNWIND=1 is opted-in for the current run.

Subject: [PATCH 1586/5214] perf kwork: Fix address sanitizer issues

There is a double free in the record array due to how parse_options
will mutate the array. Fix by keeping an array that isn't
mutated. Ensure kwork_usage is freed on all paths.

Subject: [PATCH 1587/5214] perf kwork: Fix memory management of kwork_work

This commit addresses several memory management issues in builtin-kwork.c:

1. Implements a global cleanup function perf_kwork__exit to free all
   kwork_work and kwork_atom_page objects at the end of the command.

2. Ensures all 'name' fields in struct kwork_work are malloc-ed (or NULL)
   and properly freed by using strdup and zfree.

3. Fixes memory leaks in top_merge_tasks where kwork_work objects were
   dropped without being freed.

4. Adds robustness with NULL checks for name fields.

5. Fixes workqueue_work_init to correctly resolve and strdup kernel
   function names, preventing bad-free errors.

Subject: [PATCH 1590/5214] perf test ibs: Skip privilege test on Zen6 and
 newer platforms

IBS on pre-Zen6 platforms lacked a hardware privilege filter, so the
kernel enabled swfilt=1. Zen6 and newer platforms provides privilege
filtering via the RIP[63] bit, making swfilt redundant. Skip the perf
unit test that assumes IBS has no hardware-assisted privilege filter
on Zen6 and newer platforms.

swfilt is ignored by kernel on platforms that support RIP[63] bit filter
i.e. all amd-ibs-swfilt.sh tests will test hardware assisted privilege
filter.

Without the patch on Zen6:

  # sudo ./perf test -vv 77
   77: AMD IBS software filtering:
  --- start ---
  test child forked, pid 30813
  check availability of IBS swfilt
  run perf record with modifier and swfilt
  [FAIL] IBS PMU should not accept exclude_kernel
  ---- end(-1) ----
   77: AMD IBS software filtering                            : FAILED!

With the patch:

  --- start ---
  test child forked, pid 30903
  check availability of IBS swfilt
  run perf record with modifier and swfilt

Subject: [PATCH 1591/5214] perf amd ibs: Suppress bogus TlbRefillLat and
 DCPhysAd on Zen4+

On Zen4 (and future) CPUs, IBS_OP_DATA3[TlbRefillLat] is valid only if
IBS_OP_DATA3[DcPhyAddrValid] is set. Similarly, IBS_DC_PHYSADDR is valid
if IBS_OP_DATA3[DcLinAddrValid] is _also_ set. Add these checks while
decoding IBS MSRs.

When IBS is triggered by an unprivileged user, the kernel now zeroes
PhysAddr before storing raw IBS register values in the perf sample. The
perf tool, however, still outputs these zero physical addresses, which
serves no purpose. So avoid printing zero physical addresses.

Instead of explicit family/model checks use the !zen4_ibs_extensions as
a proxy flag to cover Zen 3 and earlier revisions.

Subject: [PATCH 1594/5214] perf amd ibs: Decode Streaming-store flag in IBS OP
 raw dump

IBS OP on Zen6 and future platform can tag IBS samples that originate from
streaming-store instruction. When the PMU advertises this feature,
interpret IBS_OP_DATA2[8] bit as the streaming store indicator and show
it in the raw dump output.

Subject: [PATCH 1596/5214] perf tool_pmu: Make tool PMU events respect
 enable/disable

Tool PMU events (duration_time, user_time, system_time) currently
count from when the event is opened to when it is read. This causes
issues with features like the delay option (-D) or control fd, where
events are opened but should not start counting immediately.

Make these events behave more like regular counters by implementing
proper enable and disable support. Add accumulated_time to struct
evsel to track time while enabled, and implement enable/disable CPU
callbacks to start/stop counting.

Also generalize userspace PMU mixed group handling. Userspace synthetic
PMUs (type > PERF_PMU_TYPE_PE_END) do not have kernel implementations and
cannot be grouped in the kernel (opened with group_fd = -1), and are
skipped by kernel enable/disable calls. Iterate over group members in
userspace and manually enable/disable any members if the leader or the
member is a non-perf-event open PMU, and synchronize their disabled flags.

Closes: https://lore.kernel.org/linux-perf-users/20260517093650.2540920-1-nigro.fra@gmail.com/

Subject: [PATCH 1597/5214] perf tests: Add test for stat delay option with
 duration_time

Add a new test case `test_stat_delay` to `stat.sh` to verify that
`duration_time` correctly excludes the delay period when using the
delay option (-D).

The test runs `perf stat -D 1000 -e duration_time sleep 2` and
verifies that `duration_time` is ~1s (excluding the 1s delay), not
~2s.

Subject: [PATCH 1601/5214] scsi: scsi_debug: Remove unused variable
 sdebug_any_injecting_opt

The static variable sdebug_any_injecting_opt is no longer read. Commit
3a90a63d02b8 ("scsi: scsi_debug: every_nth triggered error injection")
removed all code that reads this variable. Hence, also remove this
variable itself. Remove SDEBUG_OPT_ALL_INJECTING because there is no
code left that uses this constant if sdebug_any_injecting_opt is
removed. This has been detected by building the scsi_debug driver with
the git HEAD version of Clang and with W=1.

Subject: [PATCH 1602/5214] scsi: megaraid_mbox: Reduce stack usage in
 megaraid_cmm_register()

The megaraid_cmm_register() function has a local copy of mraid_mmadp_t
on the stack that gets copied into the actual structure used at
runtime. When -fsanitize=thread is enabled, this causes the per-function
stack frame to grow beyond the warning limit:

megaraid_mbox.c: In function 'megaraid_cmm_register':
megaraid_mbox.c:3472:1: error: the frame size of 1312 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]

Refactor this by moving the allocation into the caller to save the extra
on-stack copy of the structure.

Subject: [PATCH 1608/5214] scsi: core: Convert INQUIRY information

Currently the vendor, model, and revision members of struct scsi_device
are pointers to fixed-length strings that are not NUL-terminated.
Fixed-precision format specifiers (e.g., "%.8s") are required whenever
they are printed and strncmp() must be used to compare these fields.
This is error-prone.

Convert these fields to fixed-size character arrays within struct
scsi_device. Remove an !sdev->model check because sdev->model is now
guaranteed not to be NULL.

This patch fixes a bug in the qla2xxx driver. It makes the following
code safe:

		if (state_flags & BIT_4)
			scmd_printk(KERN_WARNING, cp,
			    "Unsupported device '%s' found.\n",
			    cp->device->vendor);

Subject: [PATCH 1610/5214] openrisc: Add full instruction cache invalidate
 functions

Add functions to invalidate all cache lines which we will use for
static_key patching.

On OpenRISC there is no instruction to invalidate an entire cache so we
loop and invalidate cache lines one by one.  This is not extremely
expensive on OpenRISC as we usually have only a few hundred cache lines.

I considered using the invalidate cache page or range functions.
However, tracking which ranges need invalidation would have been more
expensive than flushing all pages.

Subject: [PATCH 1611/5214] openrisc: Fix jump_label smp syncing

The original commit 8c30b0018f9d ("openrisc: Add jump label support")
copies from arm64 and does not properly consider how icache invalidation
on remote cores works in OpenRISC.  On OpenRISC remote icaches need to
be invalidated otherwise static key's may remain state after updating.

Fix SMP cache syncing by:

 1. Properly invalidate remote core icaches on SMP systems by using
    icache_all_inv.  The old code uses kick_all_cpus_sync() which runs a
    no-op IPI function call on remote CPU's which does execute a lot of
    code and flushes many cache lines in the process, but does not flush
    all and it's not correct on OpenRISC.
 2. For architectures that do not have WRITETHROUGH caches be sure
    to flush the dcache after patching.

To test this I first reproduced the issue using a custom test module
[0].  The test confirmed that some icache lines maintained stale
static_key code sequences after calling static_branch_enable().  After
this patch there are no longer jump_label coherency issues.

QUP1_SE4 uses GPIO36 and GPIO37 for two selectable lane pairs. The
previous split added one function name per lane. Since these are usually
configured in pairs in devicetree, it makes more sense to have them
grouped.

So replace the per-lane qup1_se4_l[0-3] names with names for the two
selectable pairs, qup1_se4_01 and qup1_se4_23.

QUP1_SE4 uses GPIO36 and GPIO37 for two selectable lane pairs. The

However, since these are usually configured in pairs in devicetree,
it makes more sense to merge them into groups.

both GPIO36 and GPIO37 in each function group.

Subject: [PATCH 1619/5214] PCI: Add pci_suspend_retains_context() to check if
 device state is preserved during suspend

Currently, PCI endpoint drivers (e.g. nvme) use pm_suspend_via_firmware()
to check whether device state is preserved during system suspend.  If
firmware will be invoked at the end of suspend, we don't know whether
devices will retain their internal state.

But device context might be lost due to platform issues as well.  Having
those checks in endpoint drivers will not scale and will cause a lot of
code duplication.

Add pci_suspend_retains_context() as a sole point of truth that the
endpoint drivers can rely on to check whether they can expect the device
context to be retained or not.

If pci_suspend_retains_context() returns 'false', drivers need to prepare
for context loss by performing actions such as resetting the device, saving
the context, shutting it down etc. If it returns 'true', drivers do not
need to perform any special action and can leave the device in active
state.

Right now, this API only incorporates pm_suspend_via_firmware(), but will
be extended in future commits.

Subject: [PATCH 1620/5214] rust_binder: use lock_vma_under_rcu() in shrinker

The shrinker callback currently uses the mmap read trylock operation to
attempt to access the vma, but it's generally better to only lock the
vma instead of the whole mmap when you can.

When lock_vma_under_rcu() fails, there is no reason to lock the mmap
lock instead because it's already a trylock operation that is allowed to
fail.

Subject: [PATCH 1629/5214] gpib: Don't use extended registers

When the chip type is 72310 then avoid accessing extended registers
Apart from the BSR the 72310 supports only the standard NEC u7210
registers.

Subject: [PATCH 1633/5214] gpib: Suppress setting END on error from NI_USB
 dongle

The NI USB adapter sets the END bit in the status word when an error
occurs such as a read being interrupted by the setting of ATN. This
happens for example when a device clear is received from the
controller in charge during a read.

The common driver changes the error return to 0 whenever the END bit
is set in order to avoid errors such as timeout or interrupt to be
reported after the full message has actually been read. The behaviour
of the NI USB adapter in setting the END bit on errors was causing
actual errors (-EINTR, -ETIMEDOUT) not to be reported.

We avoid setting the END bit in the ni_usb_gpib driver when an error
is reported in error_code of the status from the adaptor.

Subject: [PATCH 1637/5214] char: tlclk: fix use-after-free in tlclk_cleanup()

This patch improves the module cleanup process in the tlclk driver to
prevent potential use-after-free and race conditions.

Currently, the file_operations structure does not specify the .owner
field, which could allow the module to be unloaded while user-space
processes are still interacting with the device. Additionally, the
tlclk_cleanup() function frees the alarm_events memory before ensuring
that blocked processes in the waitqueue are fully awakened and that the
switchover_timer has completed.

To address these cases, this patch:
- Sets '.owner = THIS_MODULE' in tlclk_fops to safely defer module
  unloading while the device is in use.
- Updates tlclk_cleanup() to explicitly wake up all blocked readers
  (wake_up_all), properly release hardware I/O regions, and safely
  delete the timer (timer_delete_sync) prior to freeing memory.

 pci_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Initializing structures using list initializers is harder to read than
using named initializers. Seeing the member name is more ideomatic and
easier to understand.

Use named initializers for the driver's pci_device_id array.

While at it also drop an explicit zero in the terminating array entry.

There are no changes to the compiled result of the array; verified with
builds for x86 and arm64.

Subject: [PATCH 1640/5214] misc: tifm: Use PCI_VDEVICE to initialize
 pci_device_id array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PCI_VDEVICE macro allows to assign the first four members of
pci_device_id more idiomatic and compact.

Also drop trailing zeros in the list initializer that the compiler takes
care of then. The driver doesn't use neither .class, .class_mask nor
.driver_data, so it's fine to not assign these explicitly.

There are no changes to the compiled data; confirmed using an x86 and an
arm64 build.

 time

Every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device's ACPI companion
object need to verify its presence.

Accordingly, add a requisite ACPI_COMPANION() check against NULL to the
hpet driver.

Subject: [PATCH 1643/5214] char/nvram: Remove redundant nvram_mutex

The global nvram_mutex in drivers/char/nvram.c is redundant and unused,
and this triggers compiler warnings on some configurations.

All platform-specific nvram operations already provide their own internal
synchronization, meaning the wrapper-level mutex does not provide any
additional safety.

Remove the nvram_mutex definition along with all remaining lock/unlock
users across PPC32, x86, and m68k code paths, and rely entirely on the
per-architecture nvram implementations for locking.

Subject: [PATCH 1646/5214] virt: acrn: Fix irqfd use-after-free during eventfd
 shutdown

acrn_irqfd_deassign() and the eventfd EPOLLHUP wakeup can race and free
the same struct hsm_irqfd:

  CPU0                                 CPU1
  ----                                 ----
  eventfd_release()
    wake_up_poll(EPOLLHUP)
      hsm_irqfd_wakeup()
        queue_work(&irqfd->shutdown)
                                       acrn_irqfd_deassign()
                                         hsm_irqfd_shutdown()
                                           list_del_init()
                                           eventfd_ctx_remove_wait_queue()
                                           eventfd_ctx_put()
                                         kfree(irqfd)
  hsm_irqfd_shutdown_work()
    container_of(work, ..., shutdown)
    irqfd->vm                  <-- use-after-free

The deassign path freed the irqfd while a shutdown work item was
already queued by EPOLLHUP (or vice versa), so the work item could
resurrect a dangling pointer through container_of().

Switch to the lifetime model used by KVM irqfds:

 - Deassign/deinit only deactivate the irqfd: remove it from vm->irqfds
   under irqfds_lock and queue the cleanup work.
 - hsm_irqfd_shutdown_work() becomes the sole owner that unhooks the
   eventfd waitqueue entry, drops the eventfd reference and frees the
   irqfd.
 - A new HSM_IRQFD_FLAG_SHUTDOWN bit guarded by test_and_set_bit()
   ensures the cleanup work is queued at most once, no matter how many
   of {EPOLLHUP, deassign, deinit} fire concurrently.  This is safe to
   call from the waitqueue callback, which runs with wqh->lock held and
   IRQs disabled and therefore cannot take irqfds_lock.
 - acrn_irqfd_deassign() flushes vm->irqfd_wq before returning so the
   eventfd is fully detached on return.  acrn_irqfd_deinit() deactivates
   every irqfd, flushes the workqueue and only then destroys it, so no
   path can queue_work() onto a torn-down workqueue.
 - acrn_irqfd_assign() now installs the eventfd waitqueue entry and
   publishes the irqfd to vm->irqfds under irqfds_lock, so the irqfd is
   never visible to deassign/deinit before its waitqueue entry is in
   place, and any EPOLLHUP that fires in the assign window queues
   cleanup work that blocks on irqfds_lock until publication is done.

Subject: [PATCH 1647/5214] char: dtlk: remove driver for ISA speech
 synthesizer card

The dtlk driver supports the RC Systems DoubleTalk PC ISA speech
synthesizer card. It has severe coding style issues and has only
received tree-wide fixes and drive-by cleanups in the entire Git
history (since Linux 2.6.12-rc2). The same hardware is supported by
drivers/accessibility/speakup for screen reader use, but that
implementation does not share any code with this driver. Given all of
these factors, it is likely the driver is entirely unused. Remove it to
reduce future maintenance workload.

Note: The removed maintainer is already listed in CREDITS.

-/* This driver is for the DoubleTalk PC, a speech synthesizer
-   manufactured by RC Systems (http://www.rcsys.com/).  It was written
-   based on documentation in their User's Manual file and Developer's
-   Tools disk.
-
-   The DoubleTalk PC contains four voice synthesizers: text-to-speech
-   (TTS), linear predictive coding (LPC), PCM/ADPCM, and CVSD.  It
-   also has a tone generator.  Output data for LPC are written to the
-   LPC port, and output data for the other modes are written to the
-   TTS port.
-
-   Two kinds of data can be read from the DoubleTalk: status
-   information (in response to the "\001?" interrogation command) is
-   read from the TTS port, and index markers (which mark the progress
-   of the speech) are read from the LPC port.  Not all models of the
-   DoubleTalk PC implement index markers.  Both the TTS and LPC ports
-   can also display status flags.
-
-   The DoubleTalk PC generates no interrupts.
-
-   These characteristics are mapped into the Unix stream I/O model as
-   follows:
-
-   "write" sends bytes to the TTS port.  It is the responsibility of
-   the user program to switch modes among TTS, PCM/ADPCM, and CVSD.
-   This driver was written for use with the text-to-speech
-   synthesizer.  If LPC output is needed some day, other minor device
-   numbers can be used to select among output modes.
-
-   "read" gets index markers from the LPC port.  If the device does
-   not implement index markers, the read will fail with error EINVAL.
-
-   Status information is available using the DTLK_INTERROGATE ioctl.

Subject: [PATCH 1648/5214] char: applicom: remove low-quality, unused driver

The applicom driver supports PCI Profibus cards from Applicom, later
acquired by Molex. It has severe coding style issues and has attracted
a number of bug and security fixes over the years, despite the fact
that no one appears to be using it. It was broken from at least the
beginning of Git history (Linux 2.6.12-rc2 in April 2005) until October
2008, when a fatal bug was fixed in commit bc20589bf1c6 ("applicom.c:
fix apparently-broken code in do_ac_read()"). In the commit message,
the author commented that no one they knew was able to test the change.
Since then, there have been no commits that indicate the driver is
being used. Later PCI and PCI-Express Applicom Profibus cards only
officially support Windows [1], and even the PCI-Express cards have
been discontinued [2]. Given all these factors, remove the driver to
reduce future maintenance workload.

Subject: [PATCH 1649/5214] gpib: agilent_82357a: don't check a NULL serial
 string

The agilent_82357a driver uses the USB device serial string for device
matching but does not verify that the string exists before passing it
to strcmp().

Verify that the device has a serial number before accessing it to avoid
triggering a NULL-pointer dereference with devices that don't provide
a serial number (iSerialNumber = 0).

Similar to commit aa79f996eb41 ("i2c: cp2615: fix serial string
NULL-deref at probe").

gpib_descriptor across IO ioctl operations.  In command_ioctl(), the
error path inside the loop decrements descriptor_busy and breaks, but
execution then falls through to the unconditional decrement after the
loop, underflowing the counter to -1.

This re-enables the use-after-free that the original fix was meant to
prevent: a concurrent close_dev_ioctl() sees descriptor_busy == 0 on
an actively-used descriptor and frees it.

Remove the early decrement from the error path.  The post-loop
decrement already handles all exit paths, matching the correct pattern
used in read_ioctl() and write_ioctl().

Subject: [PATCH 1652/5214] PCI: Indicate context lost if L1SS exit is broken
 during resume from system suspend

Per PCIe v7.0, sec 5.5.3.3.1, when exiting L1.2 due to an endpoint
asserting CLKREQ# signal, the REFCLK must be turned on within the latency
advertised in the LTR message.  This requirement applies to L1.1 as well.

On some platforms like Qcom, these requirements are satisfied during OS
runtime, but not while resuming from the system suspend. This happens
because the PCIe RC driver may remove all resource votes and turn off the
PHY analog circuitry during suspend to maximize power savings while keeping
the link in L1SS.

Consequently, when the endpoint asserts CLKREQ# to wake up, the RC driver
must restore the PHY and enable the REFCLK.  When this recovery process
exceeds the L1SS exit latency time (roughly L10_REFCLK_ON + T_COMMONMODE),
the endpoint may treat it as a fatal condition and trigger Link Down (LDn).
This results in a reset that destroys the internal device state.

So to indicate this platform limitation to the client drivers, introduce a
new flag 'pci_host_bridge::broken_l1ss_resume' and check it in
pci_suspend_retains_context(). If the flag is set by the RC driver, the API
will return 'false' indicating the client drivers that the device context
may not be retained and the drivers must be prepared for context loss.

Subject: [PATCH 1653/5214] PCI: qcom: Indicate broken L1SS exit during resume
 from system suspend

Qcom PCIe RCs can successfully exit from L1SS during OS runtime. However,
during system suspend, the Qcom PCIe RC driver may remove all resource
votes and turn off the PHY to maximize power savings.

Consequently, when the host is in system suspend with the link in L1SS and
the endpoint asserts CLKREQ#, the RC driver must restore the PHY and enable
the REFCLK. This recovery process causes the L1SS exit latency time to be
exceeded (roughly L10_REFCLK_ON + T_COMMONMODE). If the RC driver were to
retain all votes during suspend, L1SS exit would succeed without issue but
at the expense of higher power consumption.

When the host fails to move the link from L1SS to L0 within the
L10_REFCLK_ON + T_COMMONMODE time, the endpoint may treat it as a fatal
condition and trigger Link Down (LDn) during resume. This LDn results in a
reset that destroys the internal device state.

To ensure that the client drivers can properly handle this scenario, let
them know about this platform limitation by setting the
'pci_host_bridge::broken_l1ss_resume' flag.

Subject: [PATCH 1654/5214] nvme-pci: Use pci_suspend_retains_context() during
 suspend

pci_suspend_retains_context() lets PCI client drivers know if the platform
can retain the device context during suspend. This is decided based on
several factors like:

  - Firmware involvement at the end of suspend

  - Any platform limitation in waking from low power state (e.g., L1SS)

This API may be extended in the future to cover other platform specific
issues impacting the device low power mode during system suspend.

Use this API instead of checks like pm_suspend_via_firmware(). When
pci_suspend_retains_context() returns false, assume the platform cannot
retain the context and shutdown the controller. If it returns true, assume
that the context will be retained and keep the device in low power mode.

Subject: [PATCH 1656/5214] KVM: arm64: vgic-v5: Atomically assign bits to PPI
 DVI bitmap

For GICv5 guests we make use of the DVI mechanism for PPIs where
possible.  When mapping a virtual irq to a physical one for a GICv5
guest, the corresponding bit in the DVI bitmap is set. When unmapping,
said bit is cleared again. The key user of this mechanism is the arch
timer.

The existing code used the non-atomic __assign_bit() rather than doing
the update atomically. This could technically result in losing state
if a second PPI's DVI bit were being manipulated concurrently. Each
individual bit within the DVI bitmap is guarded using
vgic_irq->irq_lock, but there's no locking for the overall
bitmap. Therefore, switch to using the atomic assign_bit() function
instead.

Subject: [PATCH 1662/5214] irqchip/gic-v5: Immediately exec priority drop
 following activate

With GICv5 an interrupt of equal or lower priority cannot be signalled
until there has been a priority drop. This is done via the GIC CDEOI
system instruction. Once this has been executed, the hardware is able
to signal the next interrupt if there is one.

As all interrupts are programmed to have the same priority, no new
interrupts can be signalled until the priority drop has happened. This
can cause issues when, for example, an interrupt remains active while
a long running process takes place, such as when injecting a physical
interrupt into a guest VM in software.

The GICv5 driver has so far done the priority drop as part of
irq_eoi(), i.e., at the same time as deactivating the interrupt. This
means that any long running process (or VM) could block incoming
interrupts, effectively causing a denial of service for all other
interrupts.

Rather than doing the EOI as part of irq_eoi() (which the name would
suggest would be a good place for it), move it to happen immediately
after acknowledging an interrupt in the main GICv5 interrupt
handler. The deactivation of interrupts (GIC CDDI) remains implemented
as part of irq_eoi(), which means that the same interrupt cannot be
signalled a second time until deactivated by software.

Subject: [PATCH 1663/5214] KVM: arm64: Fix arch timer interrupts for
 GICv3-on-GICv5 guests

When running on a GICv5 host, we push an arch-timer-specific interrupt
domain for the timer interrupts. This interrupt domain is used to mask
the host interrupt when a GICv5 guest is running. However, this
interrupt domain is still in place when running with a GICv3 guest on
GICv5 hardware. The result is that some interrupt state changes are
not correctly propragated to the host irqchip driver for legacy
guests.

Explicitly pass irqchip state changes though to the host irqchip
driver when running a GICv3-based guest on a GICv5 host. This bypasses
all masking, and thereby operates just as a native GICv3 guest would,
with the exception of having an additional irq domain in the
hierarchy.

Subject: [PATCH 1664/5214] perf riscv: Fix discarded const qualifier in
 _get_field()

The assignment of strrchr() return values to non-const char * variables
triggers a -Werror=discarded-qualifiers warning when building with GCC
14.

This happens because in newer glibc versions, strrchr() returns a 'const
char *' if the input string is const.

Properly declare 'line2' and 'nl' as const char * to match the glibc
function signature and ensure type safety. This avoids the need for
explicit type casting and aligns with the design pattern of not
modifying read-only memory in the perf tool.

Subject: [PATCH 1665/5214] pinctrl: core: Make pin group callbacks optional
 for pin-only drivers

Currently, the pinctrl core strictly requires all drivers to implement
.get_groups_count and .get_group_name callbacks in their pinctrl_ops.

However, for simple pinctrl drivers that act purely as GPIO controllers
and pin-specific configuration proxies, without any concept of muxing or
pin groups, this strict requirement forces the implementation of dummy
callbacks just to satisfy pinctrl_check_ops().

Relax this requirement for pin-only drivers by making the group callbacks
optional when no muxing or group pin configuration support is provided.
Update the core and debugfs helpers to check for the existence of these
callbacks before invoking them.

Drivers that provide muxing or group pin configuration operations still
must implement group enumeration and naming callbacks, and are rejected
at registration time if they do not.

The controller manages various peripheral functions such as eSPI, LPC,

The binding reuses the standard pinmux and generic pin configuration

Subject: [PATCH 1667/5214] pinctrl: aspeed: Add AST2700 SoC1 support

Implement pin multiplexing (and pin configuration where applicable)
for the AST2700 SoC1 SCU pinctrl block using static SoC data tables.

Unlike legacy ASPEED pin controllers, the SoC1 pin function control
fields are highly regular, which makes it practical to describe the
packed-field register layout directly in driver data rather than reuse
the existing Aspeed pinctrl macro infrastructure.

The driver uses the generic pinctrl, pinmux and pinconf frameworks.
The controller registers are accessed via regmap from the parent
syscon, allowing shared ownership of the SCU register block.

+ *    For example, W25 maps to field index 8 (stored as 9),
+ *    meaning it occupies bits [17:16] of the first 0x4C0 register.
+ * 2. Only a subset of physical pins supports drive strength configuration.
+ *
+ * The table stores (drive strength field index + 1).
+ * The field index refers to the 2-bit drive strength field position within the
+ * 0x4C0 register range. A value of 0 indicates that the pin does not support
+ * drive strength configuration (returning -ENOTSUPP).
+ * This +1 offset allows us to rely on C's default zero-initialization for
+ * unsupported pins while avoiding compiler warnings regarding overridden
+ * initializers.

+ *
+ * Since the C preprocessor treats commas inside braces {} as argument
+ * separators for macros, we wrap lists (like mux values) in parentheses ()
+ * to protect them during macro expansion. This macro strips those
+ * parentheses when the values are needed for array initialization.

+ * FUNC() - Macro to initialize an aspeed_g7_soc1_function entry.
+ * @n: Name of the pin function.
+ * @m: Parenthesized list of mux values, mapped 1:1 to the groups list.
+ * @...: Variable list of pin group names associated with this function.
+ *
+ * This macro solves complex static initialization by:
+ * 1. Creating anonymous arrays for both group names and mux values
+ *    using C99 Compound Literals.
+ * 2. Using VM(m) to unwrap mux values into the array initializer.
+ * 3. Calculating the number of groups via sizeof() division, which
+ *    bypasses the __must_be_array() check performed by ARRAY_SIZE()
+ *    that often fails on compound literals in the kernel environment.
+ *
+ * Example: FUNC(i2c0, (1, 4), "i2c0", "di2c0")
+ *          Maps "i2c0" group to mux value 1 and "di2c0" group to mux value 4.

Subject: [PATCH 1670/5214] pinctrl: avoid duplicate function definitions

The pinctrl_generic_to_map() and pinctrl_generic_pins_function_dt_node_to_map()
functions are built whenever CONFIG_GENERIC_PINCTRL is enabled, including
configurations without CONFIG_OF.

When CONFIG_OF is disabled, the dummy definitions are also present in the header,
which causes the build to fail:

drivers/pinctrl/pinctrl-generic.c:20:5: error: conflicting types for 'pinctrl_generic_to_map'; have 'int(struct pinctrl_dev *, struct device_node *, struct device_node *, struct pinctrl_map **, unsigned int *, unsigned int *, const char **, unsigned int,  const char **, unsigned int *, unsigned int)'
   20 | int pinctrl_generic_to_map(struct pinctrl_dev *pctldev, struct device_node *parent,

  184 | pinctrl_generic_pins_function_dt_node_to_map(struct pinctrl_dev *pctldev,
      | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Removing either set of definitions is sufficient to avoid the problem.

Remove the copy from the header for simplicity.

Subject: [PATCH 1672/5214] pinctrl: spacemit: fix NULL check in
 spacemit_pin_set_config

spacemit_pin_set_config() looks up the per-pin descriptor with
spacemit_get_pin() then checks the wrong variable for failure:

	const struct spacemit_pin *spin = spacemit_get_pin(pctrl, pin);
	...
	if (!pin)
		return -EINVAL;

	reg = spacemit_pin_to_reg(pctrl, spin->pin);

pin is an unsigned int pin id, where 0 (GPIO_0 / gmac0_rxdv on K3) is a
valid pin, so rejecting it here drops the PAD config write for the first
pin of every group. On K3 Pico-ITX the GMAC RGMII group lists pin 0 as
its first entry, so its drive-strength / bias configuration was silently
ignored.

The intended guard is against spacemit_get_pin() returning NULL when the
pin id isn't in the SoC's pin table. Check spin instead, which both
restores PAD setup for pin 0 and prevents a NULL deref on spin->pin.

Subject: [PATCH 1674/5214] clk: renesas: rzg2l: Rename iterator in
 for_each_mod_clock() to avoid shadowing

Rename the internal loop iterator variable in the for_each_mod_clock()
macro from 'i' to '__i'.

The current naming conflicts with local loop variables named 'i' inside
code blocks that utilize the macro, triggering compiler warnings due to
variable shadowing:

  drivers/clk/renesas/rzg2l-cpg.c:1494:36: warning: declaration of `i` shadows a previous local [-Wshadow]
   1494 |                  for (unsigned int i = 0; i < clk->num_shared_mstop_clks; i++)

Using a unique identifier for the macro-internal iterator resolves the
shadowing warnings globally across all macro expansions.

Subject: [PATCH 1677/5214] pinctrl: renesas: rzg2l: Use -ENOTSUPP instead of
 -EOPNOTSUPP

The pinctrl and GPIO core code make exceptions for the -ENOTSUPP error
code.  One such example is gpio_set_config_with_argument_optional(),
which returns success when gpio_set_config_with_argument() returns
-ENOTSUPP, but reports failure for all other error codes.

Returning -EOPNOTSUPP from the pinctrl driver on the unsupported pinctrl
operation may lead to boot failures when pinctrl drivers implements
struct gpio_chip::set_config, the system uses GPIO hogs, and the
struct gpio_chip::set_config implementation returns -EOPNOTSUPP for the
unsupported operations.

Return -ENOTSUPP for the unsupported pinctrl operation.

Subject: [PATCH 1679/5214] remoteproc: Move resource table data structure to
 its own header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The resource table data structure has traditionally been associated with
the remoteproc framework, where the resource table is included as a
section within the remote processor firmware binary. However, it is also
possible to obtain the resource table through other means—such as from a
reserved memory region populated by the boot firmware, statically
maintained driver data, or via a secure SMC call—when it is not embedded
in the firmware.

There are multiple Qualcomm remote processors (e.g., Venus, Iris, GPU,
etc.) in the upstream kernel that do not use the remoteproc framework to
manage their lifecycle for various reasons.

When Linux is running at EL2, similar to the Qualcomm PAS driver
(qcom_q6v5_pas.c), client drivers for subsystems like video and GPU may
also want to use the resource table SMC call to retrieve and map
resources before they are used by the remote processor.

In such cases, the resource table data structure is no longer tightly
coupled with the remoteproc headers. Client drivers that do not use the
remoteproc framework should still be able to parse the resource table
obtained through alternative means. Therefore, there is a need to
decouple the resource table definitions from the remoteproc headers.

Subject: [PATCH 1680/5214] remoteproc: use rsc_table_for_each_entry() in
 rproc_handle_resources()

Replace the open-coded resource table iteration loop in
rproc_handle_resources() with the rsc_table_for_each_entry() helper.

The remoteproc-specific dispatch logic (vendor resource handling via
rproc_handle_rsc(), RSC_LAST bounds check, handler table lookup) is
moved into a local callback rproc_handle_rsc_entry(), keeping the
iteration mechanics in one canonical place.

The callback receives the payload offset within the table so that
handlers which write back into the resource table (e.g.
rproc_handle_carveout() recording a dynamically allocated address via
rsc_offset) continue to work correctly.

No functional change.

Subject: [PATCH 1681/5214] perf stat: Propagate supported flag to follower
 cgroup BPF events

When using BPF counters with cgroups, follower events (for cgroups
other than the first one) are not opened. Because they are not opened,
their `supported` flag was left as `false`.

During metric calculation, `prepare_metric` checks if the event is
supported. If it is not supported (like the follower events), it
explicitly sets the value to `NAN`, which eventually causes the metric
to be reported as `nan %`.

Fix this by propagating the `supported` flag from the "leader" events
(the ones opened for the first cgroup) to the "follower" events.

Also add a validation check to `bperf_load_program` to ensure `nr_cgroups`
is not zero and the number of events is a multiple of `nr_cgroups`,
preventing a potential division-by-zero (SIGFPE) exception when
`num_events` evaluates to 0 (e.g., with a trailing comma in cgroups list).

Subject: [PATCH 1682/5214] perf test: Add stat metrics --for-each-cgroup test

Add a new shell test `stat_metrics_cgrp.sh` to verify metric reporting
with `--for-each-cgroup`, both with and without `--bpf-counters`.

The test:
- Checks if system-wide monitoring is supported (skips if not).
- Finds cgroups to test.
- Runs `perf stat` with `insn_per_cycle` metric and verifies that the
  metric is reported for each cgroup.
- Dynamically pairs and verifies instructions and cycles counts to
  avoid false failures on idle cgroups.
- Tests both standard mode and BPF counters mode (if supported).

Fixing it by calling kvm_riscv_vcpu_config_guest_debug.

Subject: [PATCH 1686/5214] irqchip/riscv-imsic: Add nr_guest_files in per-HART
 local config

Add nr_guest_files in per-HART local config to represent the number of
guest files available on a particular HART whereas the nr_guest_files
in the global config represents the number of guest files available
across all HARTs.

This allows KVM RISC-V to use nr_guest_files from per-HART local
config for asymmetric big.Little systems.

Subject: [PATCH 1687/5214] RISC-V: KVM: AIA: Make HGEI number management fully
 per-CPU

Previously, the number of Hypervisor Guest External Interrupt (HGEI)
lines was stored in a single global variable `kvm_riscv_aia_nr_hgei`
and assumed to be the same for all HARTs. This assumption does not
hold on heterogeneous RISC-V SoCs where different cores may expose
different HGEIE CSR widths.

Introduce `nr_hgei` field into the per-CPU `struct aia_hgei_control`
and probe the actual supported HGEI count for the current HART in
`kvm_riscv_aia_enable()` using the standard RISC-V CSR probe technique:

    csr_write(CSR_HGEIE, -1UL);
    nr = fls_long(csr_read(CSR_HGEIE));
    if (nr)
        nr--;

All HGEI allocation, free and disable paths (`kvm_riscv_aia_free_hgei()`,
`kvm_riscv_aia_disable()`, etc.) now use the per-CPU value instead of
the global one.

The global `kvm_riscv_aia_nr_hgei` now represents the minimum number
of HGEI lines across HARTs and can be used to check whether HGEI
support is available or not.

This makes KVM AIA robust on big.LITTLE-style asymmetric platforms.

Subject: [PATCH 1688/5214] pinctrl: meson: amlogic-a4: fix gpio output glitch

When the system transitions from bootloader to kernel, the GPIO is
expected to keep driving high.

However, the Linux kernel first configures the pin direction and then
sets the output value. This may cause a brief low-level glitch on the
GPIO line, which can be problematic for regulator control.

By configuring the output value before switching the pin direction to
output, the glitch can be avoided.

This commit fixes the issue by swapping the configuration order.

In order to make pinctrl_generic_to_map() usable for controllers that
use pinmux, change the functions char array pointer that it passes to
pinctrl_generic_add_group() to a void pointer. In the pinmux case this
property will contain the mux setting as a number rather than as strings
in the pins + functions case.

The pinmux property is freeform, so this function mandates that the
upper 16 bits contain the pin and the lower 16 bits contains the mux
setting. The group's data pointer is populated with an array of the mux
settings for each pin it contains.

Since the node parsing and subsequent pinctrl core function calls are
practically identical to the pins + functions case, other than which
properties are examined, it makes sense to extract the common code from
pinctrl_generic_pins_function_dt_node_to_map() into a generic function
that takes the case-specific devicetree parsing function as an argument.

Subject: [PATCH 1691/5214] pinctrl: spacemit: delete
 spacemit_pctrl_check_power()

As far as I can tell spacemit_pctrl_check_power(), called during the
custom implementation of dt_node_to_map, is redundant because
the driver's implementation generate_config performs the check too.
Removing this would allow the driver to use the newly added common
function pinctrl_generic_pinmux_dt_node_to_map().

Subject: [PATCH 1692/5214] pinctrl: spacemit: move over to generic pinmux
 dt_node_to_map implementation

Replace the custom implementation of dt_node_to_map with
pinctrl_generic_dt_node_to_map() to demonstrate its use.
spacemit_pin_mux_config didn't provide much value in the first place,
because the group contains the information required to look up the
spacemit_pin struct corresponding to a pin, so there's no loss in
functionality as a result of the generic function carrying only the mux
data in the group's data pointer rather than having an array of
spacemit_pin_mux_config structs.

Subject: [PATCH 1695/5214] MIPS: RB532: attach the software node to its target
 GPIO controller

GPIOLIB wants to remove the software node's name matching against GPIO
controller's label that is going on behind the scenes in software node
lookup. To that end, we need to convert all existing users to using
software nodes actually attached to the GPIO devices they represent.

In order to use an attached software node with the GPIO controller on
rb532: convert the GPIO module into a real platform device, provide
platform device info for it in device.c and assign the software node
using its swnode field.

The software node will get inherited by the GPIO chip from the parent
platform device in devm_gpiochip_add_data() as we don't set the fwnode
using any other of the mechanisms.

Subject: [PATCH 1697/5214] MIPS: Fix big-endian stack argument fetching in o32
 wrapper

Fix an issue in call_o32() where the upper 32-bit half of incoming n64
stack arguments is fetched and used for outgoing o32 stack arguments on
big-endian platforms.

This code was adapted from arch/mips/dec/prom/call_o32.S which was meant
for a little-endian platform only and therefore using 32-bit loads from
64-bit stack slot locations holding incoming stack arguments resulted in
correct values being retrieved for data that is expected to be 32-bit.

This works on little-endian platforms where the lower 32-bit half of the
64-bit value is located at every 64-bit stack slot location.  However on
big-endian platforms the lower 32-bit half is instead located at offset
4 from every 64-bit stack slot location.

So to fix the issue the offset of 4 would have to be used on big-endian
platforms only, or alternatively a 64-bit load from the 64-bit stack
slot location can be used across the board, as the subsequent 32-bit
store to the corresponding outgoing stack argument slot will correctly
truncate the value and cause no unpredictable result.  We already take
advantage of this architectural feature for the incoming arguments held
in $a6 and $a7 registers, since the o32 wrapper does not know how many
incoming arguments there are and consequently propagates incoming data
which may not be 32-bit.

Since this code is generally supposed to be used with the stack located
in cached memory there is no extra overhead expected for 64-bit loads as
opposed to 32-bit ones, so pick this variant for code simplicity.

Subject: [PATCH 1698/5214] MIPS: Make do_IRQ() available for assembly callers

As from commit 8f99a1626535 ("MIPS: Tracing: Add IRQENTRY_EXIT section
for MIPS") do_IRQ() is not a macro anymore and can be invoked directly
from assembly code again, however its `asmlinkage' annotation has never
been brought back from the previous removal of the function with commit
187933f23679 ("[MIPS] do_IRQ cleanup").

Since calling the function directly from assembly code has a performance
advantage, add the annotation back so that the DEC platform can make use
of this again.

Subject: [PATCH 1701/5214] MIPS: DEC: Remove IRQF_ONESHOT reference for IOASIC
 DMA error IRQs

There is no need for IOASIC DMA error interrupts to use the IRQF_ONESHOT
flag, because while they do need to have the source cleared only at the
conclusion of handling, the action handler supplied is either run in the
hardirq context with interrupts disabled at the CPU level or, where IRQ
threading has been forced, the primary handler has the IRQF_ONESHOT flag
implicitly added and therefore the original action handler, now run as
the thread handler and with interrupts enabled in the CPU, is executed
with the originating interrupt line masked.  Therefore no interrupt will
retrigger regardless until the original request has been handled.

Subject: [PATCH 1702/5214] MIPS: DEC: Ensure 32-bit stack location for o32
 prom_printf()

In 64-bit configurations calling any firmware entry points from a kernel
thread other than the initial one will result in a situation where the
stack has been placed in the XKPHYS 64-bit memory segment.

Consequently the stack pointer is no longer a 32-bit value and when the
32-bit firmware code called uses 32-bit ALU operations to manipulate the
stack pointer, the calculated result is incorrect (in fact in the 64-bit
MIPS ISA almost all 32-bit ALU operations will produce an unpredictable
result when executed on 64-bit data) and control goes astray.

This may happen when no final console driver has been enabled in the
configuration and consequently the initial console continues being used
late into bootstrap, or with an upcoming change that will switch the zs
driver to use a platform device, which in turn will make the console
handover happen only after other kernel threads have already been
started, and the kernel will hang at:

  pid_max: default: 32768 minimum: 301

or somewhat later, but always before:

  cblist_init_generic: Setting adjustable number of callback queues.

has been printed.

It seems that only the prom_printf() entry point is affected.  Of all
the other entry points wired only rex_slot_address() and rex_gettcinfo()
are called from a kernel thread other than the initial one, specifically
kernel_init(), and they are leaf functions that do no business with the
stack, having worked with no issue ever since 64-bit support was added
for the platform back in 2002.

To address this issue then, arrange for the stack to be switched in the
o32 wrapper as required for prom_printf() only, by supplying call_o32()
with a pointer to a chunk of initdata space, which is placed in the
CKSEG0 32-bit compatibility segment, observing that prom_printf() is
only called from console output handler and therefore with the console
lock held, implying no need for this code to be reentrant.

Other firmware entry points may be called with interrupts enabled and no
lock held, and may therefore require that call_o32() be reentrant.  They
trigger no issue at this point and "if it ain't broke, don't fix it," so
just leave them alone.

Subject: [PATCH 1703/5214] MIPS: DEC: Prevent initial console buffer from
 landing in XKPHYS

In 64-bit configurations calling the initial console output handler from
a kernel thread other than the initial one will result in a situation
where the stack has been placed in the XKPHYS 64-bit memory segment and
consequently so has been the buffer allocated there that is used as the
argument corresponding to the `%s' output conversion specifier for the
firmware's printf() entry point.

This 64-bit address will then be truncated by 32-bit firmware, resulting
in an attempt to access the wrong memory location, which in turn will
cause all kinds of unpredictable behaviour, such as a kernel crash:

In this case the pointer in $4 was truncated from 0x980000000203bd00 to
0x000000000203bd00.

This may happen when no final console driver has been enabled in the
configuration and consequently the initial console continues being used
late into bootstrap or with an upcoming change that will switch the zs
driver to use a platform device, which in turn will make the console
handover happen only after other kernel threads have already been
started.

Fix the issue by making the buffer static and initdata, and therefore
placed in the CKSEG0 32-bit compatibility segment, observing that the
console output handler is called with the console lock held, implying
no need for this code to be reentrant.  Add an assertion to verify the
buffer actually has been placed in a compatibility segment.

Subject: [PATCH 1704/5214] mips: cps: Assemble jr.hb with an R2 ISA level

A MIPS allmodconfig built with LLVM can select CPU_MIPS32_R1 together
with MIPS_MT_SMP. In that configuration clang invokes the integrated
assembler with -march=mips32, and the MIPS MT path in cps-vec.S fails
to assemble two jr.hb instructions:

  arch/mips/kernel/cps-vec.S:376:2: error: instruction requires
  a CPU feature not currently enabled

  arch/mips/kernel/cps-vec.S:490:4: error: instruction requires
  a CPU feature not currently enabled

The earlier jr.hb in the same file is already assembled inside a .set
MIPS_ISA_LEVEL_RAW scope. The two failing sites are reached after
popping back to the file's base ISA level, so LLVM correctly rejects
them for an R1 target.

Wrap those jr.hb instructions in the same ISA-level push/pop used by
the working site. This keeps the MT code unchanged while making the
required R2 hazard-branch encoding explicit to the assembler.

Subject: [PATCH 1709/5214] MIPS: ralink: reduce ARCH_DMA_MINALIGN

Currently, Ralink SoCs use the default ARCH_DMA_MINALIGN value of 128
bytes defined in mach-generic. This is excessive for these platforms
and leads to significant memory waste in kmalloc.

Override ARCH_DMA_MINALIGN to use L1_CACHE_BYTES, which is 16 bytes for
RT288X and 32 bytes for other Ralink SoCs.

Subject: [PATCH 1710/5214] MIPS: mobileye: Remove duplicate FIT_IMAGE_FDT_EPM5
 from main Kconfig

kconfiglint reports:

  K008: config FIT_IMAGE_FDT_EPM5 has prompts in 2 separate definitions

The FIT_IMAGE_FDT_EPM5 Kconfig symbol is defined identically in two places:

  arch/mips/Kconfig:1052
  arch/mips/mobileye/Kconfig:17

Both have the same prompt, depends, default, and help text. Since
arch/mips/mobileye/Kconfig is sourced from arch/mips/Kconfig, both
definitions are parsed and the symbol ends up with two prompts.

The symbol was first introduced in commit 101bd58fde10 ("MIPS: Add
support for Mobileye EyeQ5") directly in
arch/mips/Kconfig. Three months later, commit fbe0fae601b7 ("MIPS:
mobileye: Add EyeQ6H support") created the
arch/mips/mobileye/Kconfig sub-file to organize the growing Mobileye
platform code and added the MACH_EYEQ5/MACH_EYEQ6H choice along with
a copy of FIT_IMAGE_FDT_EPM5. However, the original definition in
arch/mips/Kconfig was not removed at that time, leaving a duplicate.

Remove the definition from arch/mips/Kconfig, keeping the one in
arch/mips/mobileye/Kconfig where it belongs alongside the related
MACH_EYEQ5 machine type definition that it depends on.

Subject: [PATCH 1713/5214] PCI: qcom: Handle mixed PERST#/PHY DT configuration

The driver currently supports two PERST# and PHY DT configurations. In one
case, PHY and PERST# are described in the RC node. In the other case, they
are described in the RP node.

A mixed setup is not supported. One common example is PHY on the RP node
while PERST# remains on the RC node. In that case the driver goes through
the RP parse path, does not find PERST# on RP, and does not report an error
because PERST# is optional. Probe can then succeed silently while PERST# is
left uncontrolled, and PCIe endpoints fail to work later. This silent
probe success makes debugging difficult.

Handle this mixed case in the RP parse path by checking whether PERST# is
present on RC and, if so, using the RC PERST# GPIO for RP ports while
keeping RP parsing for PHY. Emit a warning to indicate mixed DT content so
it can be fixed.

This keeps mixed systems functional and makes the configuration issue
visible instead of failing later at endpoint bring-up.

Subject: [PATCH 1714/5214] PCI/ASPM: Add pcie_encode_t_power_on() helper to
 encode L1SS T_POWER_ON fields
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add pcie_encode_t_power_on() to encode the PCIe L1 PM Substates T_POWER_ON
parameter into the T_POWER_ON Scale and T_POWER_ON Value fields.

This helper can be used by the controller drivers to change the
default/wrong value of T_POWER_ON in L1SS capability register to avoid
incorrect calculation of LTR_L1.2_THRESHOLD value.

The helper converts a T_POWER_ON time specified in microseconds into the
appropriate scale/value encoding defined by PCIe r7.0, sec 7.8.3.2. Values
that exceed the maximum encodable range are clamped to the largest
representable encoding.

Subject: [PATCH 1715/5214] PCI: dwc: Add dw_pcie_program_t_power_on() to
 program T_POWER_ON
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The T_POWER_ON indicates the time (in μs) that a Port requires the port on
the opposite side of Link to wait in L1.2.Exit after sampling CLKREQ#
asserted before actively driving the interface. This value is used by the
ASPM driver to compute the LTR_L1.2_THRESHOLD.

Currently, some controllers expose T_POWER_ON value of zero in the L1SS
capability registers, leading to incorrect LTR_L1.2_THRESHOLD calculations,
which can result in improper L1.2 exit behavior and if AER happens to be
supported and enabled, the error may be *reported* via AER.

Add a helper to override T_POWER_ON value by the DWC controller drivers.

Subject: [PATCH 1716/5214] PCI: qcom: Program T_POWER_ON

Some platforms have incorrect T_POWER_ON value programmed in hardware.
Generally these will be corrected by bootloaders, but not all targets
support bootloaders to program correct values. That means the
LTR_L1.2_THRESHOLD value calculated by aspm.c can be wrong, which can
result in improper L1.2 exit behavior. If AER happens to be supported and
enabled, the error may be *reported* via AER.

Parse the 't-power-on-us' property from each Root Port node and program it
as part of host initialization using dw_pcie_program_t_power_on() before
link training.

This property in added to the dtschema here [1].

Subject: [PATCH 1717/5214] KVM: arm64: Reset page order in pKVM hyp_pool

When a VM fails to initialise after its stage-2 hyp_pool has been
initialised, that stage-2 must be torn down entirely. This requires
resetting both the refcount and the order of its pages back to 0.

Currently, reclaim_pgtable_pages() implicitly resets the page order by
allocating the entire pool with order-0 granularity. However, in the VM
initialisation error path, the addresses of the donated memory (the PGD)
are already known, making it unnecessary to iterate over all pages in
the pool.

Since the vmemmap page order is a hyp_pool-specific field, leaving a
non-zero order on hyp_pool destruction is harmless until another pool
attempts to admit the page. Instead of resetting this field during
destruction, reset it during pool initialization in hyp_pool_init().

For 'external' pages, we can't trust the order either as they bypass
hyp_pool_init(). Since we never coalesce them, enforce order-0 to ensure
safe insertion into the pool.

This leaves no vmemmap order users outside of hyp_pool.

In the unlikely case where insert_vm_table_entry fails, __pkvm_init_vm
release the memory donated by the host for the PGD, but as the stage-2

effectively leaking the references.

Fix the rollback with the newly added kvm_guest_destroy_stage2().

Subject: [PATCH 1719/5214] KVM: arm64: Add fail-safe for refcounted pages in
 __pkvm_hyp_donate_host

A previous bug in __pkvm_init_vm error path showed that the hypervisor
could leak refcounted pages, (i.e. losing access to a page while its
refcount is still elevated). This poses a threat to the pKVM state
machine.

Address this by introducing a fail-safe in __pkvm_hyp_donate_host.
Transitions are not a hot path so added security is worth the extra
check.

Subject: [PATCH 1721/5214] mtd: spi-nor: swp: Improve locking user experience

In the case of the first block being locked (or the few first blocks),
if the user want to fully unlock the device it has two possibilities:
- either it asks to unlock the entire device, and this works;
- or it asks to unlock just the block(s) that are currently locked,
  which fails.

It fails because the conditions "can_be_top" and "can_be_bottom" are
true. Indeed, in this case, we unlock everything, so the TB bit does not
matter. However in the current implementation, use_top would be true (as
this is the favourite option) and lock_len, which in practice should be
reduced down to 0, is set to "nor->params->size - (ofs + len)" which is
a positive number. This is wrong.

An easy way is to simply add an extra condition. In the unlock() path,
if we can achieve the same result from both sides, it means we unlock
everything and lock_len must simply be 0. A comment is added to clarify
that logic.

Subject: [PATCH 1723/5214] mtd: spi-nor: Make sure the QE bit is kept enabled
 if useful

Not all chips implement the 4BAIT table which typically indicates the
program capability, while many of them do implement the relevant SFDP
parts indicating the read capabilities. In such a situation, programs
can happen in single mode (1-1-1) and reads in quad mode (1-1-4 or
1-4-4). For the reads to work in such condition, the QE bit must be set.
In case we later use the spi_nor_write_16bit_sr_and_check() helper with
a chip with such configuration, the QE bit would get incorrectly
cleared.

Make sure this doesn't happen by keeping the QE bit under a simpler
condition:
- the quad enable hook is there (no change)
- and at least one of the two protocols is based on quad I/O cycles

Subject: [PATCH 1724/5214] mtd: spi-nor: Improve opcodes documentation

There are two status registers, named 1 and 2. The current wording is
misleading as "1" may refer to the status register ID as well as the
number of bytes required (which, in this case can be 1 or 2).

Clarify the comments by aligning them on the same pattern:
"{read,write} status {1,2} register"

Subject: [PATCH 1729/5214] mtd: spi-nor: swp: Use a pointer for SR instead of
 a single byte

At this stage, the Status Register is most often seen as a single
byte. This is subject to change when we will need to read the CMP bit
which is located in the Control Register (kind of secondary status
register). Both will need to be carried.

Change a few prototypes to carry a u8 pointer. This way it also makes it
very clear where we access the first register, and where we will access
the second.

There is no functional change.

Subject: [PATCH 1730/5214] mtd: spi-nor: swp: Create a helper that writes SR,
 CR and checks

There are many helpers already to either read and/or write SR and/or CR,
as well as sometimes check the returned values. In order to be able to
switch from a 1 byte status register to a 2 bytes status register while
keeping the same level of verification, let's introduce a new helper
that writes them both (atomically) and then reads them back (separated)
to compare the values.

In case 2 bytes registers are not supported, we still have the usual
fallback available in the helper being exported to the rest of the core.

Subject: [PATCH 1731/5214] mtd: spi-nor: swp: Rename a mask

"mask" is not very descriptive when we already manipulate two masks, and
soon will manipulate three. Rename it "bp_mask" to align with the
existing "tb_mask" and soon "cmp_mask".

Subject: [PATCH 1733/5214] mtd: spi-nor: swp: Create helpers for building the
 SR register

The status register contains 3 or 4 BP (Block Protect) bits, 0 or 1
TB (Top/Bottom) bit, soon 0 or 1 CMP (Complement) bit. The last BP bit
and the TB bit locations change between vendors. The whole logic of
buildling the content of the status register based on some input
conditions is used two times and soon will be used 4 times.

Create dedicated helpers for these steps.

Subject: [PATCH 1734/5214] mtd: spi-nor: swp: Simplify checking the
 locked/unlocked range

In both the locking/unlocking steps, at the end we verify whether we do
not lock/unlock more than requested (in which case an error must be
returned).

While being possible to do that with very simple mask comparisons, it
does not scale when adding extra locking features such as the CMP
possibility. In order to make these checks slightly easier to read and
more future proof, use existing helpers to read the (future) status
register, extract the covered range, and compare it with very usual
algebric comparisons.

As a final preparation step for the introduction of CMP support, make
a few more cosmetic changes to simplify the reading of the diff when
adding the CMP feature. In particular, define "min_prot_len" earlier as
it will be reused and move the definition of the "ret" variable at the
end of the stack just because it looks better.

Subject: [PATCH 1736/5214] mtd: spi-nor: Create a local SR cache

In order to be able to generate debugfs output without having to
actually reach the flash, create a SPI NOR local cache of the status
registers. What matters in our case are all the bits related to sector
locking. As such, in order to make it clear that this cache is not
intended to be used anywhere else, we zero the irrelevant bits.

The cache is initialized once during the early init, and then maintained
every time the write protection scheme is updated.

Subject: [PATCH 1737/5214] mtd: spi-nor: debugfs: Add locking support

The ioctl output may be counter intuitive in some cases. Asking for a
"locked status" over a region that is only partially locked will return
"unlocked" whereas in practice maybe the biggest part is actually
locked.

Knowing what is the real software locking state through debugfs would be
very convenient for development/debugging purposes, hence this proposal
for adding an extra block at the end of the file: a "locked sectors"
array which lists every section, if it is locked or not, showing both
the address ranges and the sizes in numbers of "lock sectors" (which on
small density devices is typically different than erase blocks).

Here is an example of output, what is after the "sector map" is new.

Subject: [PATCH 1738/5214] mtd: spi-nor: debugfs: Add a locked sectors map

In order to get a very clear view of the sectors being locked, besides
the `params` output giving the ranges, we may want to see a proper map
of the sectors and for each of them, their status. Depending on the use
case, this map may be easier to parse by humans and gives a more acurate
feeling of the situation. At least myself, for the few locking-related
developments I recently went through, I found it very useful to get a
clearer mental model of what was locked/unlocked.

Here is an example of output:

$ cat /sys/kernel/debug/spi-nor/spi0.0/locked-sectors-map
Locked sectors map (x: locked, .: unlocked, unit: 64kiB)
 0x00000000 (#    0): ................ ................ ................ ................
 0x00400000 (#   64): ................ ................ ................ ................

 0x01000000 (#  256): ................ ................ ................ ................

 0x03800000 (#  896): ................ ................ ................ ................
 0x03c00000 (#  960): ................ ................ ................ ..............xx

The output is wrapped at 64 sectors, spaces every 16 sectors are
improving the readability, every line starts by the first sector
offset (hex) and number (decimal).

Subject: [PATCH 1739/5214] KVM: SEV: Pin source page for write when adding
 CPUID data for SNP guest

When populating a guest_memfd instance with the initial CPUID data for an
SNP guest, acquire a writable pin on the source page as KVM will write back
the "correct" CPUID information if the userspace provided data is rejected
by trusted firmware.  Because KVM writes to the source page using a kernel
mapping, pinning for read could result in KVM clobbering read-only memory.

Note, well-behaved VMMs are unlikely to be affected, as CPUID information
is almost always dynamically generated by userspace, i.e. it's unlikely for
the CPUID information to be backed by a read-only mapping.

Subject: [PATCH 1740/5214] KVM: SEV: Unmap local kmaps in LIFO order, per
 highmem requirements

Per highmem.h, local kernel mappings must be unmapped in the reserve order
they were acquired, following a LIFO (last-in, first-out) stack-based
approach, and that failure to do so "is invalid and causes malfunction".

Swap the kunmap_local() calls in SNP post-populate flow to ensure the
mappings are released in the correct order.

Note, because SNP is 64-bit only, the bugs are benign as there are no
highmem mappings to unwind.

 release
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The scan_mask lifetime changed in commit 9a2e1233d38c ("iio: buffer:
hw-consumer: remove redundant scan_mask flexible array").

Before that change, the scan mask storage was embedded in struct
hw_consumer_buffer, so iio_hw_buf_release() could free the whole
allocation with a single kfree(hw_buf).

That commit moved the scan mask to a separate bitmap_zalloc() allocation
stored in buffer.scan_mask, but left iio_hw_buf_release() unchanged.

Free the scan mask in iio_hw_buf_release() before freeing the buffer
wrapper.

tmp006_probe() allocates the DRDY trigger with devm_iio_trigger_alloc()
but registers it with plain iio_trigger_register(). The driver has no
.remove() callback, so on module unload the trigger stays in the global
trigger list while its memory is freed by devm, leaving a dangling
entry.

Switch to devm_iio_trigger_register() so the registration is undone in
the same devm scope as the allocation.

iadc_probe() calls enable_irq_wake() after a successful
devm_request_irq(), but the driver has no remove callback or
matching disable_irq_wake(), so the wake reference count on the
IRQ is leaked on module unload or driver unbind.

Check the IRQ request error first, then register a devm action
that calls disable_irq_wake() so the wake reference is released
in the same scope as the enable. While here, drop the inverted
"if (!ret) ... else return ret" in favour of the standard
"if (ret) return ret;" pattern.

If the *ppos value is non-zero then simple_write_to_buffer() will not
initialize the start of the buf[] buffer.  Non-zero ppos values aren't
going to work at all.  Check for that at the start of the function and
return -ENOSPC.

Subject: [PATCH 1751/5214] KVM: guest_memfd: Return -EEXIST for overlapping
 bindings

KVM_SET_USER_MEMORY_REGION2 rejects guest_memfd ranges that overlap an
existing binding, but kvm_gmem_bind() currently reports the failure through
its generic -EINVAL path.  That makes binding conflicts indistinguishable
from malformed guest_memfd parameters.

Return -EEXIST when the target guest_memfd range is already bound, matching
the errno used for overlapping GPA memslots and making the two types of
range conflicts report the same class of error to userspace.

Note, returning -EINVAL was definitely not intentional, as guest_memfd
support was accompanied by a selftest to verify that attempting to create
overlapping bindings fails with -EEXIST.  Except the selftest was also
flawed in that it unintentionally overlapped memslot GPAs, and so failed
on KVM's common memslot checks before reaching guest_memfd.

Subject: [PATCH 1752/5214] KVM: selftests: Test guest_memfd binding overlap
 without GPA overlap

The guest_memfd binding overlap test recreates the deleted slot with GPA
ranges that overlap the still-live slot.  KVM rejects those attempts from
the generic memslot overlap check before reaching kvm_gmem_bind(), so the
test can pass even if guest_memfd binding overlap detection is broken.

Recreate the slot at its original, non-overlapping GPA and use guest_memfd
offsets that overlap the front and back halves of the other slot's binding.
Expand the guest_memfd so the back-half case remains within the file size.

 when checking for >= 0

When conditionally closing a memory region's guest_memfd file descriptor,
cast the field to a signed it so that negative values are correctly
detected.  Because selftests reuse "struct kvm_userspace_memory_region2"
instead of providing custom storage, they pick up the kernel uAPI's __u32
definition of the file descriptor, not the more common "int" definition,
e.g. that's used for userspace_mem_region.fd.

 before reaping the bitmap

In the dirty log test, randomize the delay before the initial call to get
the dirty log bitmap for a given iteration, so that the amount of memory
dirtied by the guest varies from iteration to iteration, and so that the
user can effectively control the duration (by increasing the interval).

Always waiting 1ms effectively hides a KVM RISC-V bug as the test reaps the
dirty bitmap before the guest has a chance to trigger the problematic flow
in KVM.

Subject: [PATCH 1758/5214] KVM: selftests: hyperv_features: test write of 1 to
 HV_X64_MSR_RESET

Writing 1 to HV_X64_MSR_RESET triggers a real vCPU reset; the test
was writing 0 because the host loop was not prepared to handle the
resulting KVM_EXIT_SYSTEM_EVENT. Add the missing handling and write
1 to actually exercise the reset path.

Subject: [PATCH 1759/5214] KVM: x86: Widen x86_exception's error_code to 64
 bits

Widen the error_code field in struct x86_exception from u16 to u64 to
accommodate AMD's NPF error code, which defines information bits above
bit 31, e.g. PFERR_GUEST_FINAL_MASK (bit 32), and PFERR_GUEST_PAGE_MASK
(bit 33).

Retain the u16 type for the local errcode variable in walk_addr_generic
as the walker synthesizes conventional #PF error codes that are
architecturally limited to bits 15:0.

Subject: [PATCH 1760/5214] x86/tdx: Use PFN directly for mapping guest private
 memory

Remove struct page assumptions/constraints in the SEAMCALL wrapper APIs for
mapping guest private memory and have them take PFN directly.

Having core TDX make assumptions that guest private memory must be backed
by struct page (and/or folio) will create subtle dependencies on how
KVM/guest_memfd allocates/manages memory (e.g., whether it uses memory
allocated from core MM, if the memory is refcounted, or if the folio is
split) that are easily avoided. [1].

KVM's MMUs work with PFNs. This is very much an intentional design choice.
It ensures that the KVM MMUs remain flexible and are not too tied to the
regular CPU MMUs and the kernel code around them. Using 'struct page' for
TDX guest memory is not a good fit anywhere near the KVM MMU code [2].

Use "kvm_pfn_t pfn" for type safety. Using this KVM type is appropriate
since APIs tdh_mem_page_add() and tdh_mem_page_aug() are exported to KVM
only.

Subject: [PATCH 1761/5214] x86/tdx: Use PFN directly for unmapping guest
 private memory

Remove struct page assumptions/constraints in APIs for unmapping guest
private memory and have them take physical address directly.

Having core TDX make assumptions that guest private memory must be backed
by struct page (and/or folio) will create subtle dependencies on how
KVM/guest_memfd allocates/manages memory (e.g., whether it uses memory
allocated from core MM, if the memory is refcounted, or if the folio is
split) that are easily avoided. [1].

KVM's MMUs work with PFNs. This is very much an intentional design choice.
It ensures that the KVM MMUs remain flexible and are not too tightly tied
to the regular CPU MMUs and the kernel code around them. Using
"struct page" for TDX guest memory is not a good fit anywhere near the KVM
MMU code [2].

Therefore, for unmapping guest private memory: export
tdx_quirk_reset_paddr() for direct KVM invocation, and convert the SEAMCALL
wrapper API tdh_phymem_page_wbinvd_hkid() to take PFN as input (thus
updating mk_keyed_paddr() and tdh_phymem_page_wbinvd_tdr()).

Intentionally have KVM pass PAGE_SIZE (rather than KVM_HPAGE_SIZE(level))
to tdx_quirk_reset_paddr() in tdx_sept_remove_private_spte() to avoid
mixing in huge page changes. The KVM_BUG_ON() check for !PG_LEVEL_4K in
tdx_sept_remove_private_spte() justifies using PAGE_SIZE.

Do not convert tdx_reclaim_page() to use PFN as input since it currently
does not remove guest private memory.

Use "kvm_pfn_t pfn" for type safety. Using this KVM type is appropriate
since APIs tdh_phymem_page_wbinvd_hkid() and tdx_quirk_reset_paddr() are
exported to KVM only.

Subject: [PATCH 1762/5214] x86/tdx: Drop exported function
 tdx_quirk_reset_page()

KVM invokes tdx_quirk_reset_page() to reset TDX control pages (including
S-EPT pages, TDR page, etc.), as all those pages are allocated by KVM TDX
and thus always have struct page.

However, it's also reasonable for KVM to reset those TDX control pages via
tdx_quirk_reset_paddr() directly, eliminating the need to export two
parallel APIs. Keeping tdx_quirk_reset_page() as a one-line helper in the
header file is also unnecessary.

No functional change intended.

Subject: [PATCH 1764/5214] KVM: x86: Tell ->inject_page_fault() whether or a
 fault came from hardware

When injecting a page fault (including nested TDP faults into L1), tell the
injection routine whether or not the fault originated in hardware, i.e. if
KVM is effectively forwarding a fault it intercept.  For nested TDP fault
injection, KVM needs to grab PAGE_WALK vs. GUEST_FINAL information from the
VMCB/VMCS, _if_ the fault originated in hardware.

Note, simply checking whether or not the original exit was due a #NPF or
EPT Violation isn't sufficient/correct, as the fault being synthesized for
L1 may or may not be the "same" fault that triggered a VM-Exit from L2.
E.g. if access to emulated MMIO in L2 hits a !PRESENT fault (EPT Violation
or #NPF), e.g. because MMIO caching is disabled or it's the first time the
GPA has been accessed by L2, then KVM will enter the emulator.  If
emulating the MMIO instruction then hits a nested TDP fault, e.g. because
L2 was accessing MMIO with a MOVSQ (memory-to-memory move), or because L1
has since unmapped the code stream, then the TDP fault synthesized to L1
will not be the same emulated fault the triggered the VM-Exit.

No functional change intended (nothing uses the new param, yet...).

Subject: [PATCH 1765/5214] KVM: SVM: Fix nested NPF injection of
 PFERR_GUEST_{PAGE,FINAL}_MASK bits

Fix KVM's generation of PFERR_GUEST_{PAGE,FINAL}_MASK bits when injecting a
Nested Page Fault into L1.  Currently, KVM blindly stuffs GUEST_FINAL into
L1, which is blatantly wrong given that KVM obviously generates NPFs for
page table accesses.

There are two paths that trigger NPF injection: hardware NPF exits (from
L2) and emulation-triggered faults, i.e. when KVM detects a NPF as part of
emulating an L2 GVA access.  For the hardware case, use the bits verbatim
from the VMCB, as KVM is simply forwarding a NPF to L1.  For the emulation
case, propagate the GUEST_{PAGE,FINAL} bits from the access field (which
were recently added for MBEC+GMET support).

To differentiate between the two cases, add "hardware_nested_page_fault"
to "struct x86_exception", and set it when injecting a NPF in response to
an NPF exit from L2.

To help guard against future goofs, assert that exactly one of GUEST_PAGE
or GUEST_FINAL is set when injecting a NPF.  Unlike VMX, there are no
(known) cases where hardware doesn't set either bit, and KVM should always
set one or the other when emulating a GVA access.

Subject: [PATCH 1766/5214] KVM: VMX: Synthesize nested EPT violation
 GVA_IS_VALID/GVA_TRANSLATED bits

When injecting an EPT Violation into L2 in response to a fault detected
while emulating an L2 GVA access, synthesize the GVA_IS_VALID and
GVA_TRANSLATED bits using information provided by the walker, instead of
pulling the bits from vmcs02.EXIT_QUALIFICATION.  The information in
vmcs02.EXIT_QUALIFICATION is valid/correct if and only if the fault being
injected into L1 is the direct result of an EPT Violation VM-Exit from L2.

E.g. if KVM is emulating an I/O instruction and the memory operand's
translation through L1's EPT fails, using vmcs02.EXIT_QUALIFICATION is
wrong as the semantics for EXIT_QUALIFICATION would be for an I/O exit,
not an EPT Violation exit.

Opportunistically clean up the formatting for creating the mask of bits
to pull from vmcs02.EXIT_QUALIFICATION.

Subject: [PATCH 1767/5214] KVM: selftests: Add nested page fault injection
 test

Add a test that exercises nested page fault injection during L2
execution. L2 executes I/O string instructions (OUTSB/INSB) that access
memory restricted in L1's nested page tables (NPT/EPT), triggering a
nested page fault that L0 must inject to L1.

The test supports both AMD SVM (NPF) and Intel VMX (EPT violation) and
verifies that:
  - The exit reason is an NPF/EPT violation
  - The access type and permission bits are correct
  - The faulting GPA is correct

Three test cases are implemented:
  - Unmap the final data page (final translation fault, OUTSB read)
  - Unmap a PT page (page walk fault, OUTSB read)
  - Write-protect the final data page (protection violation, INSB write)
  - Write-protect a PT page (protection violation on A/D update, OUTSB
    read)

Subject: [PATCH 1768/5214] KVM: x86: Treat KVM's virtual PMU as disabled for
 TDX VMs

Introduce a "protected PMU" concept, and use it to disable KVM's virtual
PMU for TDX VMs, as the PMU state for TDX VMs is virtualized by the TDX
Module[1], i.e. _can't_ emulated/virtualized by KVM, and KVM doesn't yet
support enabling/exposing PMU functionality for/to TDX VMs.  For now,
simply treat the PMU as disabled, as it's not clear what all needs to be
changed, e.g. KVM needs to do at least:

 1) Configure TD_PARAMS to allow guests to use performance monitoring.
 2) Restrict the TD to a subset of the PEBS counters if supported.
 3) Limit the TD to setup a certain perfmon events using basic/enhanced
    event filtering.

Explicitly disallow enabling the PMU via KVM_CAP_PMU_CAPABILITY for VMs
with a protected PMU to prevent userspace from circumventing KVM's
protections.

Subject: [PATCH 1776/5214] MIPS: alchemy: mtx1: attach software nodes to GPIO
 chips

GPIO subsystem is switching the way it locates GPIO chip instances for
GPIO references in software nodes from matching on node names to
identity matching, which necessitates assigning firmware nodes
(software nodes) to GPIO chips.

Move the node definitions for alchemy-gpio1 and alchemy-gpio2 to
arch/misp/alchemy/common/gpiolib.c, register them there, and attach
them to gpio_chip instances. Adjust MTX1 board file to use these nodes.

Note that because nodes need to be registered before they can be used in
PROPERTY_ENTRY_GPIO() we have to do the registration at
postcore_initcall level, otherwise (due to the link order) MTX1 board
initialization code will run first.

Subject: [PATCH 1777/5214] MIPS: alchemy: db1000: use nodes attached to GPIO
 chips in properties

GPIO subsystem is switching the way it locates GPIO chip instances for
GPIO references in software nodes by doing identity matching instead of
matching on node names. Switch to using software nodes attached to gpio
chips instead of using freestanding software nodes.

Also stop supplying platform data for the spi-gpio controller since
spi-gpio driver can derive number of chipselect lines from device
properties.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The R-Car VIN driver already uses a scratch buffer to sustain capture
operations in absence of a frame buffer provided by userspace.

There is no reason to require 4 buffers queued at all times for the
driver to operate. Drop min_queued_buffers from the VIN driver to allow
single-frame capture operations.

Subject: [PATCH 1781/5214] media: staging: imx-csi: move media_pipeline to
 video device

The imx-media driver has a single imx_media_device. Attaching the
media_pipeline to the imx_media_device prevents the execution of multiple
media pipelines on the device. This should be possible as long as the
media_pipelines don't use the same pads or pads that be configured while
the other media pipeline is streaming.

Move the media_pipeline to the imx_media_video_dev to be able to construct
media pipelines per imx capture device.

If different media pipelines in the media device conflict, the validation
will fail. Thus, the pipeline will fail to start and signal an error to
user space.

 pipeline on pad 0

entity->pads is an array that contains all the pads of an entity.

Calling __media_pipeline_start() or __media_pipeline_stop() on the pads,
implicitly starts the pipeline with the first pad in this array as origin.

Explicitly use the first pad to start the pipeline to make this more
obvious to the reader.

Subject: [PATCH 1784/5214] media: staging: imx: remove unnecessary
 out-of-memory error message

Remove dev_err() call after dma_alloc_coherent() failure.

checkpatch.pl reports this as an unnecessary out-of-memory message because
failure is already conveyed by returning -ENOMEM, and the current message
does not provide additional useful debugging information.

Subject: [PATCH 1789/5214] dt-bindings: mtd: nand: Add nand-randomizer
 property

Add the 'nand-randomizer' property to control the data randomizer
feature. This is used to improve data reliability by reducing
cell-to-cell interference.

Depending on the hardware architecture, this property is designed to be
generic and can apply to either the NAND chip's internal randomizer
or the hardware randomizer engine embedded in the NAND host controller.

This property is defined as a uint32 enum (0 or 1) instead of a simple
boolean. This design choice explicitly supports the "not present" case.
If the property is omitted, the driver will not interfere and will leave
the randomizer in its current state (e.g., as already configured by the
bootloader or hardware default).

Subject: [PATCH 1790/5214] mtd: spinand: Add support for randomizer

This patch adds support for the randomizer feature.

It introduces a 'set_randomizer' callback in 'struct spinand_info' and
'struct spinand_device'.

If a driver implements this callback, the core will invoke it during
device initialization (spinand_init) to enable or disable the randomizer
feature based on the device tree configuration.

Subject: [PATCH 1791/5214] mtd: spinand: macronix: Enable randomizer support

Implement the 'set_randomizer' callback for Macronix SPI NAND chips.
The randomizer is enabled by setting bit 1 of the Configuration Register
(address 0x10).

This patch adds support for the following chips:
  - MX35LFxG24AD series
  - MX35UFxG24AD series

When the randomizer is enabled, data is scrambled internally during
program operations and automatically descrambled during read operations.
This helps reduce bit errors caused by program disturbance.

Please refer to the following link for randomizer feature:

Use kzalloc_obj() / kzalloc_objs() to allocate the memcard structs,
instead of kmalloc_obj() / kmalloc_objs() to prevent access to
uninitialized data.

Fixes runtime error: Fault in unaligned fixup: 0000 [#1] at
mtd_get_fact_prot_info.

Subject: [PATCH 1795/5214] mtd: rawnand: qcom: embed nand_controller into
 qcom_nand_controller

The qcom_nand_controller had a struct nand_controller *controller
pointer that was assigned to (struct nand_controller *)&nandc[1],
with the allocation oversized by sizeof(*controller) to make room.
get_qcom_nand_controller() then walked backwards from chip->controller
using sizeof()-based arithmetic to recover the enclosing nandc.

Embed the nand_controller directly into qcom_nand_controller and use
container_of() in get_qcom_nand_controller(). The header now needs
the full rawnand.h definition rather than a forward declaration.

Subject: [PATCH 1797/5214] mtd: Consistently define pci_device_ids
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Initializing a pci_device_id using plain list expressions is hard to
understand for a human who isn't into the Linux PCI subsystem. So for
each initializer use one of the PCI_DEVICE macros for .vendor, .device,
.subvendor and .subdevice and named initializers for the remaining
assignments. This makes it easier to parse and also more robust against
chagnes to the struct definition.

Also drop useless zeros and commas.

The mentioned robustness is relevant for a planned change to struct
pci_device_id that replaces .driver_data by an anonymous union.

This change doesn't introduce changes to the compiled pci_device_id
array. Tested on x86 and arm64.

Subject: [PATCH 1798/5214] mtd: inftlmount: convert printk(KERN_WARNING) to
 pr_warn

Replace all printk(KERN_WARNING ...) calls with pr_warn() to follow
the kernel's recommended logging style and resolve checkpatch warnings.
Also convert one bare printk() that was missing a log level.

No functional change.

There were four MTD maps drivers that were used with AMD Élan SoCs.
Since 486-class CPU support was removed in commit 8b793a92d862 ("x86/cpu:
Remove M486/M486SX/ELAN support"), it is no longer possible to actually
use these. Three of them have already been removed, so remove the
remaining driver entirely.

Subject: [PATCH 1800/5214] mtd: maps: remove uclinux map driver

Rather than using platform data or DT properties, the configuration
for this mtd map driver used to be passed through the global
uclinux_ram_map structure, but the last instance was removed in
commit 4ba66a976072 ("arch: remove blackfin port") in 2018.

After commit 251f26c9e828 ("mtd: maps: Make uclinux_ram_map static"),
it became impossible to configure it at all, even with out-of-tree
platform code.

Clearly nobody is using it, so remove it.

Subject: [PATCH 1801/5214] mtd: maps: remove obsolete impa7 map driver

This driver was originally merged in 2002 for a board using
the Cirrus Logic CL/PS711x platform, but the actual board
file never made it upstream.

The SoC platform is still supported but uses devicetree
based probing, so if anyone ever wanted to upstream board
support, they would just use the regular physmap driver.

Subject: [PATCH 1802/5214] iio: chemical: scd30: Cleanup initializations and
 fix sign-extension bug

Include linux/bitfield.h for FIELD_GET().

Create new macros for bit manipulation in combination with manual bit
manipulation being replaced with FIELD_GET().

The current variable declaration and initializations are barely readable
and use comma separations across multiple lines. Refactor the
initializations so that mantissa and exp have separate declarations and
sign gets initialized later.

In addition (and due to the nature of the cleanup), fix a sign-extension
bug where, float32 would get bitwise anded with ~BIT(31)
(which is 0xFFFFFFFF7FFFFFFF) which corrupted the exponent.

Subject: [PATCH 1803/5214] powerpc tools perf: Initialize error code in
 auxtrace_record_init function

perf trace record fails some cases in powerpc

 # perf test "perf trace record and replay"
 128: perf trace record and replay                                    : FAILED!

  # perf trace record sleep 1
  # echo $?
    32

This is happening because of non-zero err value from
auxtrace_record__init() function.

 static int record__auxtrace_init(struct record *rec)
 {
        int err;

        if ((rec->opts.auxtrace_snapshot_opts || rec->opts.auxtrace_sample_opts)
            && record__threads_enabled(rec)) {
                pr_err("AUX area tracing options are not available in parallel streaming mode.\n");
                return -EINVAL;
        }

        if (!rec->itr) {
                rec->itr = auxtrace_record__init(rec->evlist, &err);
                if (err)
                        return err;
        }

Here "int err" is not initialised. The code expects "err" to be set from
auxtrace_record__init() function.

Update auxtrace_record__init() in arch/powerpc/util/auxtrace.c to clear
err value in the beginning.

- Clear err value in beginning of function. Any fail later will
set appropriate return code to err.

- Even if we haven't found any event for auxtrace, perf record
should continue for other events. NULL return
will indicate that there is no auxtrace record initialized.

- Not having "err" set here will affect monitoring of other events
also because perf record will fail seeing random value in err.

Set err to -EINVAL before invoking auxtrace_record__init() in
builtin-record.c

With the fix,

  # perf trace record sleep 1
  [ perf record: Woken up 2 times to write data ]
  [ perf record: Captured and wrote 0.033 MB perf.data (228 samples) ]

Subject: [PATCH 1804/5214] iio: light: opt3001: fix missing state reset on
 timeout

Currently in the function opt3001_get_processed(), there is a check
that directly returns -ETIMEDOUT if the conversion IRQ times out,
completely bypassing the err label, leaving ok_to_ignore_lock
permanently true, potentially breaking the device's falling threshold
interrupt detection.

Assign -ETIMEDOUT to the return variable and jump to the error label
to ensure ok_to_ignore_lock is properly reset.

Subject: [PATCH 1806/5214] perf: Extract is_ignored_kernel_symbol() for kernel
 mapping symbol filtering

Mapping symbol filtering is scattered across multiple files with
inconsistent checks.  The kernel's own is_mapping_symbol() covers x86
local symbols ('.L*' and 'L0*') on top of the '$' prefix used by
ARM/AArch64/RISC-V, but the perf tool only checks '$'.

Extract is_ignored_kernel_symbol() into symbol.h matching the kernel
definition, and convert the kallsyms and ksymbol event paths to use it.
Add ksymbol event name validation and early mapping symbol filtering
before any state mutation.

Subject: [PATCH 1807/5214] perf: Apply is_ignored_kernel_symbol() filter in
 ELF loading path for kernel DSOs

dso__load_sym_internal() had no filtering for .L* and L0* mapping
symbols while the kallsyms path already filters them via
is_ignored_kernel_symbol().

Add the same check gated by dso__kernel() so that kernel ELF objects
(vmlinux, .ko) have mapping symbols filtered across all architectures,
but userspace ELF objects are unaffected -- '$' is a valid prefix in
languages like Java and Scala.

The existing ARM/AArch64 and RISC-V architecture-specific mapping symbol
checks are preserved; the new is_ignored_kernel_symbol() check adds x86
local symbol (.L*, L0*) filtering and provides unified
cross-architecture coverage for kernel DSOs.

 dependencies

Fix missing #include of pmu.h found while cleaning the evsel/evlist
header files. Sort the remaining header files for consistency with the
rest of the code. Doing this exposed a missing forward declaration of
addr_location in print_insn.h, add this and sort the forward
declarations.

Subject: [PATCH 1819/5214] pinctrl: nuvoton: ma35d1: fix MFP register offset
 and pin table

Each GPIO bank has two 32-bit MFP registers: MFPL covering pins 0-7
at the bank base offset, and MFPH covering pins 8-15 at base offset+4.
ma35_pinctrl_parse_groups() computed the register address without
accounting for this split, so any pin with an index >= 8 within its
bank was written to the wrong register.

Also fix the pin descriptor table in pinctrl-ma35d1.c: switch from
sequential to 16-per-bank pin numbering, add missing PC8-PC11 pins
and their mux options, and remove the duplicate PN10-PN15 entries.

Fixes: f805e356313b ("pinctrl: nuvoton: Add ma35d1 pinctrl and GPIO driver")

Subject: [PATCH 1820/5214] pinctrl: cs42l43: Fix leaked pm reference on error
 path

Returning directly if the regmap_update_bits() fails causes a pm runtime
reference to be leaked, let things run to the end of the function
instead.

The debounce bit sets a bypass on the debounce rather than enabling it,
as such the current polarity of the debounce is set incorrectly. Invert
the polarity to correct this.

Subject: [PATCH 1822/5214] mtd: spi-nor: Add steps for testing locking support

As recently raised on the mailing list, it may be useful to propose a
list of steps to go through in order to prove the devices have been
described correctly, especially since all the block protection
information is not stored in any kind of table and is instead filled
manually by developers.

Use the debugfs output to ease the comparison between expectations and
reality.

+5) If your flash supports locking, please go through the following test
+   procedure to make sure it correctly behaves. The below example
+   expects the typical situation where eraseblocks and lock sectors have
+   the same size. In case you enabled MTD_SPI_NOR_USE_4K_SECTORS, you
+   must adapt `bs` accordingly.
+
+   Warning: These tests may hard lock your device! Make sure:
+
+   - The device is not hard locked already (#WP strapped to low and
+     SR_SRWD bit set)
+   - If you have a WPn pin, you may want to set `no-wp` in your DT for
+     the time of the test, to only make use of software protection.
+     Otherwise, clearing the locking state depends on the WPn
+     signal and if it is tied to low, the flash will be permanently
+     locked.
+
+   Test full chip locking and make sure expectations, the MEMISLOCKED
+   ioctl output, the debugfs output and experimental results are all
+   aligned::

Subject: [PATCH 1823/5214] mtd: spi-nor: swp: Add support for the complement
 feature

The current locking implementation allows to select a power of two
number of blocks, which is going to be the protected amount, as well as
telling whether this is the data at the top (end of the device) or the
bottom (beginning of the device). This means at most we can cover half
of the device or the entire device, but nothing in between.

The complement feature allows a much finer grain of configuration, by
allowing to invert what is considered locked and unlocked.

Add support for this feature. The only known position for the CMP bit is
bit 6 of the configuration register.

The locking and unlocking logics are kept unchanged if the CMP bit is
unavailable. Otherwise, once the regular logic has been applied, we
check if we already found an optimal configuration. If not, we try with
the CMP bit set. If the coverage is closer to the request, we use it.

This chip has support for the locking complement (CMP) feature. Add

Unfortunately, this chip also comes with an incorrect BFPT table,
indicating the Control Register cannot be read back. This is wrong,
reading back the register works and has no (observed) side effect. The
datasheet clearly indicates supporting the 35h command and all bits from
the CR are marked readable. QE and CMP bits are inside, and can be
properly read back.

Add a fixup for this, otherwise it would defeat the use of the CMP
feature.

Subject: [PATCH 1834/5214] KVM: arm64: Guard against NULL vcpu on VHE hyp
 panic path

On VHE, __hyp_call_panic() unconditionally calls __deactivate_traps(vcpu)
on the vcpu pointer read from host_ctxt->__hyp_running_vcpu. That pointer
is cleared after every guest exit (and is never set when no guest is
running), so an unexpected EL2 exception landing in _guest_exit_panic,
e.g. via the el2t*_invalid / el2h_irq_invalid vectors - reaches this
function with vcpu == NULL. __deactivate_traps() then dereferences vcpu
via ___deactivate_traps() -> vserror_state_is_nested() -> vcpu_has_nv()
-> vcpu->arch.features, faulting inside the panic handler and obscuring
the original failure.

The nVHE counterpart (hyp_panic() in arch/arm64/kvm/hyp/nvhe/switch.c)
already guards its vcpu-using cleanup with "if (vcpu)"; mirror that
here. sysreg_restore_host_state_vhe() does not depend on vcpu and
continues to run unconditionally, preserving panic forensics. The
trailing panic("...VCPU:%p", vcpu) prints "(null)" safely via printk's
%p handling.

Subject: [PATCH 1835/5214] KVM: arm64: Fix __deactivate_fgt macro parameter
 typo

__deactivate_fgt() declares its first parameter as "htcxt" but the body
references "hctxt". The parameter is unused; the macro silently captures
"hctxt" from the enclosing scope. Both existing callers
(__deactivate_traps_hfgxtr() and __deactivate_traps_ich_hfgxtr()) happen
to define a local "struct kvm_cpu_context *hctxt", so the macro works
by coincidence.

A future caller without an "hctxt" local in scope, or naming it
differently, would compile but bind to the wrong context. Align the
parameter name with the sibling __activate_fgt() macro.

The "vcpu" parameter remains unused in the body, kept for API symmetry
with __activate_fgt() (which uses it).

The hypercall handlers call pkvm_refill_memcache() to top up the
hyp_vcpu memcache before invoking __pkvm_host_{share,donate}_guest().
pkvm_ownership_selftest invokes those functions directly with a
static selftest_vcpu that has an empty memcache.

Seed selftest_vcpu's memcache from the prepopulated selftest
pages, leaving the remainder for selftest_vm.pool. Required by
the memcache-sufficiency pre-check added in the following

Subject: [PATCH 1837/5214] KVM: arm64: Pre-check vcpu memcache for host->guest
 share

__pkvm_host_share_guest() ends with kvm_pgtable_stage2_map() to
install the guest stage-2 mapping, after a forward pass that mutates
the host vmemmap (sets PKVM_PAGE_SHARED_OWNED and increments
host_share_guest_count) for every page in the range. The map's
return value is wrapped in WARN_ON() and otherwise discarded,
asserting that the call cannot fail.

WARN_ON() at nVHE EL2 panics, so this assertion is only correct if
the call genuinely cannot fail. kvm_pgtable_stage2_map() can fail
with -ENOMEM when the stage-2 walker exhausts the caller's
memcache, and the host controls the vcpu memcache via the topup
interface, so an under-provisioned share request would otherwise
turn a recoverable -ENOMEM into a fatal hyp panic.

Bound the worst-case walker allocation in the existing pre-check
pass so that kvm_pgtable_stage2_map() cannot fail at the call
site, using kvm_mmu_cache_min_pages() -- the same bound host EL1
uses for its own stage-2 maps. If the vcpu memcache holds fewer
pages, return -ENOMEM before any state mutation.

Subject: [PATCH 1838/5214] KVM: arm64: Pre-check vcpu memcache for host->guest
 donate

__pkvm_host_donate_guest() flips the host stage-2 PTE for the
donated page to a non-valid annotation via
host_stage2_set_owner_metadata_locked() and then calls
kvm_pgtable_stage2_map() to install the matching guest stage-2
mapping. The map's return value is wrapped in WARN_ON() and
otherwise discarded, asserting that the call cannot fail.

WARN_ON() at nVHE EL2 panics, so this assertion is only correct
if the call genuinely cannot fail. kvm_pgtable_stage2_map() can
fail with -ENOMEM even at PAGE_SIZE granularity: the donate path
verifies PKVM_NOPAGE for the guest IPA before the map, so the
walker must allocate fresh page-table pages from the vcpu
memcache, and the host controls the vcpu memcache via the topup
interface. An under-provisioned donation request would otherwise
turn a recoverable -ENOMEM into a fatal hyp panic.

Bound the worst-case walker allocation alongside the existing
__host_check_page_state_range() / __guest_check_page_state_range()
pre-checks, using the helper introduced for host->guest share. If
the vcpu memcache holds fewer pages than kvm_mmu_cache_min_pages(),
return -ENOMEM before any state mutation.

Subject: [PATCH 1840/5214] KVM: arm64: Don't populate TPIDR_EL2 in
 finalise_el2()

Currently, it is not necessary for __finalise_el2() to configure
TPIDR_EL2:

* The hyp stub code does not consume the value of TPIDR_EL2.

* On the boot cpu, TPIDR_EL1 is used for the percpu offset until the
  ARM64_HAS_VIRT_HOST_EXTN cpucap is detected and boot alternatives
  are patched. Before boot alternatives are patched,
  cpu_copy_el2regs() will copy TPIDR_EL1 into TPIDR_EL2. It is not
  necessary for __finalise_el2() to initialise TPIDR_EL2 before this.

* Secondary CPUs are brought up after boot alternatives have been
  patched, and __secondary_switched() will initialize TPIDR_EL2 in
  'init_cpu_task', after finalise_el2() calls __finalise_el2()

* KVM hyp code which may consume TPIDR_EL2 is brought up after all
  secondaries have been booted, once TPIDR_El2 has been configured on
  all CPUs.

Remove the redundant initialisation from __finalise_el2().

checking for 'pdev->is_physfn. But 'pdev->is_physfn' is only set for the
physical function of a SR-IOV capable device. But for the non-SR-IOV device
this variable will be 0. So this check ended up breaking the health check
functionality for all non-SR-IOV devices.

Fix it by checking for '!pdev->is_virtfn' to make sure that the check is
only skipped for virtual functions.

Subject: [PATCH 1843/5214] KVM: x86: Consolidate CPUID fault handling for
 emulator and interception logic

Extract the logic for emulating CPUID faulting (where CPUID #GPs at CPL>0
outside of SMM) into a dedicated helper and use the helper for both the
full emulator and the intercepted-CPUID paths.

Opportunistically drop kvm_require_cpl(), as kvm_emulate_cpuid() was the
one and only user.

No functional change intended.

[jim: Add EXPORT_STATIC_CALL_GPL(kvm_x86_get_cpl) so that KVM vendor
modules can call kvm_is_cpuid_allowed(). Fix typo in commit message.]

Subject: [PATCH 1844/5214] KVM: x86: Prioritize CPUID faulting over CPUID
 VM-exits in nested VMX

Per the Intel SDM, "Certain exceptions have priority over VM exits.  These
include invalid-opcode exceptions, faults based on privilege level, and
general-protection exceptions that are based on checking I/O permission
bits in the task-state segment (TSS)."

Ensure that when L2 executes CPUID at CPL > 0 while L1 has enabled CPUID
faulting, KVM intercepts the exit in L0 and queues #GP rather than
forwarding the CPUID VM-exit to L1.

Empirical testing confirms that this #GP has higher precedence than a CPUID
VM-exit on Granite Rapids (F/M/S 6/0xad/1).

Subject: [PATCH 1845/5214] KVM: x86: Remove supports_cpuid_fault() helper

The function, supports_cpuid_fault(), tests specifically for guest support
of Intel's CPUID faulting feature. It does not test for guest support of
AMD's CPUID faulting feature.

To avoid confusion, remove the helper.

Subject: [PATCH 1846/5214] KVM: x86: Virtualize AMD CPUID faulting

On AMD CPUs, CPUID faulting support is advertised via
CPUID.80000021H:EAX.CpuidUserDis[bit 17] and enabled by setting
HWCR.CpuidUserDis[bit 35].

Advertise the feature to userspace regardless of host CPU support. Allow
writes to HWCR to set bit 35 when the guest CPUID advertises
CpuidUserDis. Update cpuid_fault_enabled() to check HWCR.CpuidUserDis as
well as MSR_FEATURE_ENABLES.CPUID_GP_ON_CPL_GT_0.

Unlike VMX, SVM prioritizes the CPUID intercept over the #GP induced by
CPUID faulting.[1] This behavior has been confirmed on a Turin CPU (F/M/S
1AH/2/1).

Subject: [PATCH 1851/5214] KVM: TDX: Drop kvm_x86_ops.link_external_spt()

Drop the dedicated .link_external_spt() for linking S-EPT pages, and
instead funnel everything through .set_external_spte() for mapping S-EPT
entries. Using separate hooks doesn't help prevent TDP MMU details from
bleeding into TDX, and vice versa; to the contrary, dedicated callbacks
will result in _more_ pollution when hugepage support is added, e.g. will
require the TDP MMU to know details about the splitting rules for TDX that
aren't all that relevant to the TDP MMU.

Ideally, KVM would provide a single pair of hooks to set S-EPT entries,
one hook for setting SPTEs under write-lock and another for setting SPTEs
under read-lock (e.g. to ensure the entire operation is "atomic", to allow
for failure, etc.).  Sadly, TDX's requirement that all child S-EPT entries
are removed before the parent makes that impractical: the TDP MMU
deliberately prunes non-leaf SPTEs and _then_ processes its children, thus
making it quite important for the TDP MMU to differentiate between zapping
leaf and non-leaf S-EPT entries.

However, that's the _only_ case that's truly special, and even that case
could be shoehorned into a single hook; it just wouldn't be a net positive.

Subject: [PATCH 1852/5214] KVM: TDX: Wrap mapping of leaf and non-leaf S-EPT
 entries into helpers

Add a helper, tdx_sept_map_leaf_spte(), to wrap and isolate PAGE.ADD and
PAGE.AUG operations. Rename tdx_sept_link_private_spt() to
tdx_sept_map_nonleaf_spte() to wrap SEPT.ADD for symmetry.

Thus, transition tdx_sept_set_private_spte() into a "dispatch" routine for
setting/writing S-EPT entries.

No functional change intended.

Subject: [PATCH 1854/5214] KVM: x86/mmu: Plumb param "old_spte" into
 kvm_x86_ops.set_external_spte()

If tdp_mmu_set_spte_atomic() triggers an atomic zap on a mirror SPTE
(though currently no paths trigger it), the change is propagated via the
set_external_spte() op. Plumb the old SPTE into the set_external_spte() op,
so TDX code rather than TDP MMU code can warn if the atomic zap isn't
allowed, i.e. to let TDX enforce TDX's rules (inasmuch as possible).

Rename mirror_spte to new_spte to follow the TDP MMU's naming, and to make
it more obvious what value the parameter holds.

Opportunistically tweak the ordering of parameters to match the pattern of
most TDP MMU functions, which do "old, new, level".

Subject: [PATCH 1855/5214] KVM: TDX: Move KVM_BUG_ON()s in
 __tdp_mmu_set_spte_atomic() to TDX code

Drop some KVM_BUG_ON()s that are guarding against TDP MMU attempting to
propagate unsupported changes to the external page table through
__tdp_mmu_set_spte_atomic(). Have TDX code trigger them instead.

Now that TDP MMU logically allows propagating atomic zapping operation to
the external page table through the set_external_spte() op in
__tdp_mmu_set_spte_atomic(), TDX code will trigger the KVM_BUG_ON() on the
atomic zapping request instead. (Note: non-atomic zapping is not propagated
via the set_external_spte() op yet).

Despite the generic naming, external page table ops are designed completely
around TDX. They hook the bare minimum of what is needed, and exclude the
operations that are not supported by TDX. To help wrangle which operations
are handleable by various operations, warnings and KVM_BUG_ON()s exist in
the code. These warnings and KVM_BUG_ON()s put the burden of understanding
which operations should be forwarded to TDX code on TDP MMU developers, who
often read the code without TDX context.

Future changes will transition the encapsulation of this domain knowledge
to TDX code by funneling the external page table updates through a central
update mechanism. In this paradigm, the central update mechanism can
encapsulate the special knowledge, but will not have as much knowledge
about what operation is in progress.

Subject: [PATCH 1856/5214] KVM: TDX: Move lockdep assert in
 __tdp_mmu_set_spte_atomic() to TDX code

Move the MMU lockdep assert in __tdp_mmu_set_spte_atomic() into the TDX
specific op because the assert is TDX specific in intention.

The TDP MMU has many lockdep asserts for various scenarios, and in fact
the callchains that are used for TDX already have a lockdep assert which
covers the case in __tdp_mmu_set_spte_atomic(). However, these asserts are
for management of the TDP root owned by KVM. In the
__tdp_mmu_set_spte_atomic() assert case, it is helping with a scheme to
avoid contention in the TDX module during zap operations. That is very
TDX specific.

One option would be to just remove the assert in
__tdp_mmu_set_spte_atomic() and rely on the other ones in the TDP MMU. But
that assert is for a different intention, and too far away from the
SEAMCALL that needs it. So just move it to TDX code.

Subject: [PATCH 1857/5214] KVM: x86/tdp_mmu: Morph !is_frozen_spte() check
 into a KVM_MMU_WARN_ON()

Remove the conditional logic for handling the setting of mirror page table
to frozen in __tdp_mmu_set_spte_atomic() and add it as a warning for both
mirror and direct cases.

The mirror page table needs to propagate PTE changes to the external page
table. This presents a problem for atomic updates which can't update both
page tables at once. So a special value, FROZEN_SPTE, is used as a
temporary state during these updates to prevent concurrent operations on
the PTE. If the TDP MMU tried to install FROZEN_SPTE as a long-term value,
it would confuse these updates.

On the other hand, it would also confuse other threads if FROZEN_SPTE is
installed as a long-term value for direct page tables (e.g., causing
another thread working on atomic zap to wait for a !FROZEN_SPTE value
endlessly).

Therefore, add the warning for installing FROZEN_SPTE as a long-term value
in __tdp_mmu_set_spte_atomic() without differentiating whether it's a
mirror or direct page table.

Subject: [PATCH 1859/5214] KVM: VMX: Handle bad values on proxied writes to
 LBR MSRs

Use the "safe" WRMSR API when writing LBRs on behalf of the guest (or host
userspace), and propagate any errors back to the instigator, as the value
being written is untrusted.  E.g. if the guest (or host userspace) attempts
to set reserved bits in LBR_SELECT, then KVM needs to return an error, and
not WARN on the bad value.

Continue using the "unsafe" version of RDMSR, as it should be impossible to
reach the helper with a completely bogus MSR, i.e. WARNing on RDMSR failure
is very desirable, e.g. to make KVM bugs more visible.

  unchecked MSR access error: WRMSR to 0x1c8 (tried to write 0x0000000000004000)
  Call Trace:

Subject: [PATCH 1860/5214] KVM: TDX: Allow userspace to return errors to guest
 for MAPGPA

MAPGPA request from TDX VMs gets split into chunks by KVM using a loop
of userspace exits until the complete range is handled.

In some cases userspace VMM might decide to break the MAPGPA operation
and continue it later. For example: in the case of intrahost migration
userspace might decide to continue the MAPGPA operation after the
migration is completed.

Allow userspace to signal to TDX guests that the MAPGPA operation should
be retried the next time the guest is scheduled.

This is potentially a breaking change since if userspace sets
hypercall.ret to a value other than EBUSY or EINVAL an EINVAL error code
will be returned to userspace. As of now QEMU never sets hypercall.ret
to a non-zero value after handling KVM_EXIT_HYPERCALL so this change
should be safe.

Subject: [PATCH 1862/5214] KVM: x86/tdp_mmu: Centrally propagate
 to-present/atomic zap updates to external PTEs

Move propagation of to-present changes and atomic zap changes to external
PTEs from function __tdp_mmu_set_spte_atomic() to function
__handle_changed_spte(), which centrally handles changes of SPTEs.

When setting a PTE to present in the mirror page tables, the update needs
to be propagated to the external page tables (in TDX parlance, the S-EPT).
Today this is handled by special mirror page tables logic/branching in
__tdp_mmu_set_spte_atomic(), which is the only place where present PTEs are
set for TDX.

The current approach obviously works, but is a bit hacked on. The hook for
setting present leaf PTEs is added only where TDX happens to need it. For
example, TDX does not support any of the operations that use the non-atomic
variant, tdp_mmu_set_spte(), to set present PTEs. Since the hook is missing
there, it is very hard to understand the code from a non-TDX lens. If the
reader doesn't know the TDX specifics it could look like the external SPTE
update is missing.

In addition to being confusing, it also litters the TDP MMU with "external"
update callbacks. This is especially unfortunate because there is already a
central place to react to TDP updates, handle_changed_spte().

Begin the process of moving towards a model where all mirror page table
updates are forwarded to TDX code where the TDX-specific logic can live
with a more proper separation of concerns. Do this by adding a helper
__handle_changed_spte() and teaching it how to return error codes, such
that it can propagate the failures that may come from TDX external page
table updates. Make the original handle_changed_spte() a no-fail version of
__handle_changed_spte(), so it handles no-fail changes which are under
exclusive mmu_lock or under the no-fail path handle_removed_pt(),
triggering KVM_BUG_ON() on error returns.

Instead of having __tdp_mmu_set_spte_atomic() do the frozen mirror SPTE
dance and trigger propagation to external PTEs, make
__tdp_mmu_set_spte_atomic() a simple helper of try_cmpxchg64() and hoist
the frozen mirror SPTE dance up a level to tdp_mmu_set_spte_atomic(). Then,
the propagation of changes to present to the external PTEs can be
centralized to __handle_changed_spte(). Aging external SPTEs is not yet
supported for the mirror page table, so just warn on mirror usage in
kvm_tdp_mmu_age_spte() and invoke __tdp_mmu_set_spte_atomic() directly
without frozen dance. No need to warn on installing FROZEN_SPTE as a
long-term value in kvm_tdp_mmu_age_spte() since removing accessed bit is
mutually exclusive with installing FROZEN_SPTE (FROZEN_SPTE is with
accessed bit in all x86 platforms).

Since tdp_mmu_set_spte_atomic() can also be invoked to atomically zap SPTEs
(though there's no path to trigger atomic zap on the mirror page table up
to now), also leverage set_external_spte() op to propagate the atomic zaps
when tdp_mmu_set_spte_atomic() zaps leaf SPTEs directly. (When
tdp_mmu_set_spte_atomic() zaps a non-leaf SPTE, zaps of the child leaf
SPTEs are propagated via the remove_external_spte() op).

Note: tdp_mmu_set_spte_atomic() invokes __handle_changed_spte() to handle
changes to new_spte while the mirror SPTE is frozen, so
(1) the update of the external PTEs and statistics, or
(2) the update of child mirror SPTEs, child external PTEs and corresponding
    statistics,
now occur before the mirror SPTE is actually set to new_spte.
(1) is ok since if it fails, the mirror SPTE will be restored to its
original value. (2) is also ok since handle_removed_pt() is no-fail.

Subject: [PATCH 1863/5214] KVM: x86/mmu: Drop KVM_BUG_ON() on shared lock to
 zap child external PTEs

Drop the KVM_BUG_ON() in the KVM MMU core before zapping child external
PTEs, since requiring zapping PTEs to be protected by exclusive mmu_lock is
TDX's specific requirement.

No need to plumb the shared/exclusive info into the remove_external_spte()
op or move the KVM_BUG_ON() to TDX, because
- There's already an assertion of exclusive mmu_lock protection in TDX.
- The KVM_BUG_ON() is a bit redundant given that if there's any bug causing
  zapping of leaf PTEs in S-EPT under shared mmu_lock, SEAMCALL failures
  due to contention would result in TDX_BUG_ON() in TDX.

Subject: [PATCH 1865/5214] KVM: TDX: Drop kvm_x86_ops.remove_external_spte()

Drop kvm_x86_ops.remove_external_spte(), and instead handle the removal of
leaf SPTEs in the S-EPT (a.k.a. external page table) in
kvm_x86_ops.set_external_spte(). This will also allow extending
tdx_sept_set_private_spte() to support splitting a huge S-EPT entry without
needing yet another kvm_x86_ops hook.

Now all changes for removing leaf mirror SPTEs are propagated through
kvm_x86_ops.set_external_spte().
- When removing leaf mirror SPTEs under shared mmu_lock (though currently
  no path can trigger this scenario and TDX does not support this
  scenario), tdx_sept_remove_private_spte() may produce a warning due to
  lockdep_assert_held_write() or may return -EIO and trigger TDX_BUG_ON()
  due to concurrent BLOCK, TRACK, REMOVE.
- When removing leaf mirror SPTEs under exclusive mmu_lock, all errors are
  unexpected. If any error occurs in this scenario,
  tdx_sept_remove_private_spte() will return -EIO and trigger KVM_BUG_ON().
  A redundant KVM_BUG_ON() call will also be triggered in TDP MMU core in
  handle_changed_spte(), which is benign (the WARN will fire if and only if
  the VM isn't already bugged).

Subject: [PATCH 1867/5214] KVM: x86: Move error handling inside
 free_external_spt()

Move the logic for TDX's specific need to leak pages when reclaim
fails inside the free_external_spt() op, so this can be done in TDX
specific code and not the generic MMU.

Do this by passing in "sp" instead of the external page table pointer.
This way, TDX code can set sp->external_spt to NULL. Since the error is now
handled internally in TDX code (by triggering KVM_BUG_ON() or
TDX_BUG_ON_3(), which warn and stop the VM on any error), change the op to
return void. This way it also operates like a normal free in that success
is guaranteed from the caller's perspective.

Opportunistically, drop the unused level and gfn args while adjusting the
sp arg.

The TDP MMU supports traversing the TDP without holding locks. Page tables
need to be freed via RCU to prevent walking one that gets freed.

While none of these lockless walk operations actually happen for the mirror
page table, the TDP MMU nonetheless frees the mirror page table in the same
way, and (because it's a handy place to plug it in) the external page table
as well.

However, the external page table definitely can't be walked once the page
table pages are reclaimed from the TDX module. The TDX module releases the
page for the host VMM to use, so this RCU-time free is unnecessary for the
external page table.

So move the free_page() call to TDX code. Create an
tdp_mmu_free_unused_sp() to allow for freeing external page tables that
have never left the TDP MMU code (i.e. don't need to be freed in a special
way).

Subject: [PATCH 1869/5214] KVM: nSVM: Stop leaking single-stepping on VMRUN
 into L2

According to the APM, TF on VMRUN causes a #DB after VMRUN completes on
the _host_ side. However, KVM injects a #DB in L2 context instead (or
exits to userspace if KVM_GUESTDBG_SINGLESTEP is set) in
kvm_skip_emulated_instruction().

Avoid single-step handling on VMRUN by open-coding the rest of
kvm_skip_emulated_instruction() in nested_svm_vmrun(). This doesn't look
pretty, but following changes will need to open-code
kvm_pmu_instruction_retired() anyway, and will cleanup the code.  This
ignores TF on VMRUN instead of injecting a spurious exception into
L2. Document this virtualization hole with a FIXME.

Note that a failed VMRUN would have been correctly single-stepped, but
now TF is always ignored for consistency and simplicity purposes.  VMX
does not support TF on a successful VMLAUNCH/VMRESUME, so it's unlikely
that single-stepping VMRUN properly is important, especially if it's
only for failed VMRUNs.

Subject: [PATCH 1870/5214] KVM: nSVM: Bail early out of VMRUN emulation if
 advancing RIP fails

If svm_skip_emulation_instruction() fails, then RIP could not be
advanced correctly (e.g. decode failure when NextRIP is not available).
KVM will exit to userspace to handle the emulation failure, but only
after stuffing the wrong RIP into vmcb01 and entering guest mode.

Bail early and exit to userspace before committing any side-effects of
emulating the VMRUN (e.g. entering guest mode).

Subject: [PATCH 1871/5214] KVM: nSVM: Unify RIP and PMU handling calls when
 emulating VMRUN

The code paths for advancing RIP and retiring the instruction for RIP
are very similar whether or not caching vmcb12 succeeds. The only
difference is handling mapping failures (i.e. EFAULT).

Pull the mapping failure handling out and unify the calls to
svm_skip_emulated_instruction() and kvm_pmu_instruction_retired(), but
return immediately after if copying and caching vmcb12 failed. A nice
side effect of this is that the FIXME comment is now above the only code
path calling svm_skip_emulated_instruction().

Subject: [PATCH 1872/5214] KVM: nSVM: Move VMRUN instruction retirement after
 entering guest mode

A successful VMRUN retires in guest mode and should be counted by the
PMU as a guest instruction. Move the call to
kvm_pmu_instruction_retired() after potentially entering guest mode,
such that VMRUN is counted correctly.

The PMU event will be matched against L2's CPL, but otherwise this does
not change the behavior in terms of guest vs. host, because KVM does
not virtualize Host-Only/Guest-Only PMC controls yet, so all
instructions are counted regardless of the vCPU's host/guest state. But
this change is needed for the incoming support for Host-Only/Guest-Only
controls to count VMRUN correctly.

clarifying that it is more similar to

Opportunistically rename the argument from 'diff' to 'counters'.

Subject: [PATCH 1876/5214] KVM: x86/pmu: Check mediated PMU counter enablement
 before event filters

If the guest disables the counter (by clearing
ARCH_PERFMON_EVENTSEL_ENABLE), KVM still performs the PMU filter lookup,
even though it doesn't end up changing eventsel_hw.  Check if the
counter is enabled by the guest before doing the potentially expensive
PMU filter lookup.

Subject: [PATCH 1878/5214] KVM: x86/pmu: Disable counters based on
 Host-Only/Guest-Only bits in SVM

Introduce an optional per-vendor PMU callback for checking if a counter
is disabled in the current mode, and register a callback on AMD to
disable a counter based on the vCPU's setting of Host-Only or Guest-Only
EVENT_SELECT bits with the mediated PMU.

If EFER.SVME is set, all events are counted if both bits are set or
cleared. If only one bit is set, the counter is disabled if the vCPU
context does not match the set bit.

If EFER.SVME is cleared, the counter is disabled if any of the bits is
set, otherwise all events are counted. Note that a Linux guest correctly
handles this and clears Host-Only when EFER.SVME is cleared, see commit
1018faa6cf23 ("perf/x86/kvm: Fix Host-Only/Guest-Only counting with SVM
disabled").

The callback is made from pmc_is_locally_enabled(), which is used for
the mediated PMU when updating eventsel_hw in
kvm_mediated_pmu_refresh_eventsel_hw(), as well as when checking what
PMCs count instructions/branches for emulation in
kvm_pmu_recalc_pmc_emulation().

Host-Only and Guest-Only bits are currently reserved, so this change is
a noop, but the bits will be allowed with mediated PMU in a following
change when fully supported.

Instead of always checking of a counter needs to be disabled for
mode-specific reasons (e.g. Host-Only/Guest-Only bits in SVM), add a
bitmap to track such counters. Set the bit for counters using either
Host-Only or Guest-Only bits in EVENTSEL on SVM.

This bitmap will also be reused in following changes to selectively
apply changes to such counters.

Subject: [PATCH 1880/5214] KVM: x86/pmu: Reprogram Host/Guest-Only counters on
 nested transitions

Reprogram PMU counters on nested transitions for the mediated PMU, to
re-evaluate Host-Only and Guest-Only bits and enable/disable the PMU
counters accordingly. For example, if Host-Only is set and Guest-Only is
cleared, a counter should be disabled when entering guest mode and
enabled when exiting guest mode.

According to the APM, when EFER.SVME is cleared, setting Host-Only or
Guest-Only disables the counter, so also trigger counter reprogramming
when EFER.SVME is toggled.

Counters setting any of Host-Only and Guest-Only bits are already being
tracked in pmc_has_mode_specific_enables, use the bitmap to reprogram
these counters.

Reprogram the counters synchronously on nested VMRUN/#VMEXIT and
EFER.SVME toggling. This is necessary as these instructions are counted
based on the new CPU state (after the instruction is retired in
hardware).  Hence, the PMU needs to be updated before instruction
emulation is completed and kvm_pmu_instruction_retired() is called.

Defer reprogramming the counters when force leaving guest mode through
svm_leave_nested() to avoid potentially reading stale state (e.g.
incorrect EFER). All flows force leaving nested are non-architectural,
so accuracy is irrelevant.

Refactor a helper out of kvm_pmu_request_reprogram_counters() that
accepts a boolean allowing synchronous vs deferred reprogramming, and
use that from SVM code to support both scenarios.

The current code decodes TCR.TG0/TG1 and VTCR.TG0 inline at several

Subject: [PATCH 1884/5214] KVM: arm64: nv: Use literal granule size in TLBI
 range calculation

TLBI handling derives the invalidation range from guest VTCR_EL2.TG0 in
get_guest_mapping_ttl() and compute_tlb_inval_range(). Switch these to
use a helper that returns the decoded VTCR_EL2.TG0 granule size instead
of decoding it inline.

This keeps the granule size derivation in one place and prepares for
following changes that adjust the effective granule size.

Subject: [PATCH 1885/5214] KVM: arm64: Fallback to a supported value for
 unsupported guest TGx

When KVM derives the translation granule for emulated stage-1 and
stage-2 walks, it decodes TCR/VTCR.TGx and treats the granule as-is.
This is wrong when the guest programs a granule size that is not
advertised in the guest's ID_AA64MMFR0_EL1.TGRAN* fields.
Architecturally, such a value must be treated as an implemented granule
size. Choose an available one while prioritizing PAGE_SIZE.

Subject: [PATCH 1886/5214] thunderbolt: Prevent XDomain delayed work
 use-after-free on disconnect

tb_xdp_handle_request() runs on system_wq and queues
xd->state_work via queue_delayed_work() in three request handlers:
PROPERTIES_CHANGED_REQUEST, UUID_REQUEST (via start_handshake),
and LINK_STATE_CHANGE_REQUEST.  Similarly, update_xdomain() queues
xd->properties_changed_work when local properties change.

Concurrently, tb_xdomain_remove() calls stop_handshake() which does
cancel_delayed_work_sync() on both delayed works.  Later,
tb_xdomain_unregister() calls device_unregister() which eventually
frees the xdomain.  Since commit 559c1e1e0134 ("thunderbolt: Run
tb_xdp_handle_request() in system workqueue") moved the request
handler off tb->wq, the handler and the remove path are no longer
serialized.  If queue_delayed_work() executes after
cancel_delayed_work_sync() but before the xdomain is freed, the
delayed work fires on a freed object.

Add xd->removing that tb_xdomain_remove() sets under xd->lock
before calling stop_handshake().  Each external queue site holds
the same lock and checks removing before calling
queue_delayed_work().  This provides the mutual exclusion needed:
either the queue site acquires the lock first and queues work that
the subsequent cancel will see, or the remove path acquires the
lock first and the queue site observes removing == true and skips
the queue.

Fixes: 559c1e1e0134 ("thunderbolt: Run tb_xdp_handle_request() in system workqueue")

Subject: [PATCH 1887/5214] platform/x86: uniwill-laptop: Rework FN lock/super
 key suspend handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the suspend handling for the FN lock and super key enable
features saves the whole values of the affected registers instead of
the individual feature state. This duplicates the register access
logic from the associated sysfs attributes.

Rework the suspend handling to reuse said register access logic and
only store the individual feature state as a boolean value.

Subject: [PATCH 1888/5214] platform/x86: uniwill-laptop: Mark EC_ADDR_OEM_4 as
 volatile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It turned out that EC_ADDR_OEM_4 also contains bits with a volatile
nature. Mark the whole register as volatile to prepare for the usage
of said bits. This also means that we now have to save/restore the
touchpad toggle state ourself.

Subject: [PATCH 1889/5214] platform/x86: uniwill-laptop: Add support for
 battery charge modes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Many Uniwill-based devices do not supports the already existing
charge limit functionality, but instead support an alternative
interface for controlling the battery charge algorithm.

Add support for this interface and update the documentation.

+The ``uniwill-laptop`` driver supports controlling the battery charge limit. This either happens
+over the standard ``charge_control_end_threshold`` or ``charge_types`` power supply sysfs attribute,
+depending on the device. When using the ``charge_control_end_threshold`` sysfs attribute, all values
+between 1 and 100 percent are supported. When using the ``charge_types`` sysfs attribute, the driver
+supports switching between the ``Standard``, ``Trickle`` and ``Long Life`` profiles.
+
+Keep in mind that when using the ``charge_types`` sysfs attribute, the EC firmware will hide the
+true charging status of the battery from the operating system, potentially misleading users into
+thinking that the charging profile does not work. Checking the ``current_now`` sysfs attribute
+tells you the true charging status of the battery even when using the ``charge_types`` sysfs
+attribute (0 means that the battery is currently not charging).
 
 Additionally the driver signals the presence of battery charging issues through the standard
 ``health`` power supply sysfs attribute.

Subject: [PATCH 1892/5214] KVM: s390: Track page size in struct guest_fault

Until now, the members of struct guest_fault are always accessed while
holding the required locks, and thus the ptep and crstep pointers can
be dereferenced safely.

There will be some new cases where callers of kvm_s390_faultin_gfn()
need to know the size of the page used to solve the fault, at which
point no locks are held anymore, and dereferencing the crstep field
is not possible.

Introduce a new crste_region3 flag for struct guest_fault to indicate
whether the crstep used to solve the fault was a region 3 entry with FC=1
(large pud).

This allows to disambiguate all three possible scenarios:
* If ptep is not NULL, the fault was solved with a pte.
* If ptep is NULL and crste_region3 is 0, a segment entry with FC=1
  (large pmd) was used.
* If ptep is NULL and crste_region3 is 1, a region 3 entry with FC=1
  (large pud) was used.

Implement and enable the KVM_PRE_FAULT_MEMORY ioctl for s390.

Faulted-in pages will be marked as accessed, unlike x86, otherwise they
will trigger a minor fault when accessed. Avoiding such faults is one of
the points of KVM_PRE_FAULT_MEMORY.

LWMI_OM_SYSFS_NAME.

Subject: [PATCH 1900/5214] platform/x86: lenovo-wmi-other: Add WMI battery
 charge limiting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add charge_behaviour and charge_types attributes through a power supply
extension for devices that support WMI based charge enable & disable.

Lenovo Legion devices that implement WMI function and capdata ID
0x03010001 in their BIOS are able to enable or disable charging at 80%
through the lenovo-wmi-other interface. Add a charge_types attribute for
BATX devices to expose this capability with Standard and Long_Life types
enabled.

Additionally, devices that support WMI function and capdata ID 0x03020000
are able to force discharge of the battery. Expose this capability with
a charge_behaviour attribute in the power supply extension, with the auto
and force-discharge behaviors enabled. The GET method for this attribute
is bugged. After analyzing the DSDT, and some testing, it appears the
method grabs bit(3) instead of bit(4) from the EC register that stores the
current status, and will only report if charging has been inhibited or
not. To work around this, store and report the last setting written to the
attribute.

As some devices only expose one attribute or the other, a bitmask is
added with a lookup table and some helper macros to select the correct
configuration for the hardware at runtime.

The ideapad_laptop driver provides the charge_types attribute to provide
similar functionality. When the WMI method is set this can corrupt the
ACPI method return and cause hardware and driver errors. To avoid
conflicts between the drivers, we get the acpi_handle and do the same
check that ideapad_laptop does when it enables the feature. If the
feature is supported in ideapad_laptop, abort adding the extension from
lenovo-wmi-other. The ACPI method is more reliable when both are
present from my testing, so we can prefer that implementation and do
not need to worry about de-conflicting from inside that driver.

Subject: [PATCH 1901/5214] platform/x86: lenovo-wmi-other: Add
 force_load_psy_ext module parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some Lenovo BIOS have been shown to have incomplete and/or broken
capability data and WMI attribute IDs. In some cases the capability data
reports that a feature is not supported when the get/set methods are
fully implemented. It is also possible that the ACPI methods from the
ideapad_laptop driver we defer to could be bugged while the WMI method
is fully working. To aid end users in submitting more complete bug
reports in these situations, add an override to skip the ACPI and
compatibility checks to force load the power supply extension as if it
is fully supported and has no conflicts.

We are about to add debugfs support for lenovo-wmi-capdata. Let's setup
a debugfs directory called "lenovo_wmi" for tidiness, so that any
lenovo-wmi-* device can put its subdirectory under the directory.
Subdirectories will be named after the corresponding WMI devices.

Subject: [PATCH 1903/5214] platform/x86: lenovo-wmi-capdata: Add debugfs file
 for dumping capdata
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Lenovo GameZone/Other interfaces have some delicate divergences
among different devices. When making a bug report or adding support for
new devices/interfaces, capdata is the most important information to
cross-check with.

Add a debugfs file (lenovo_wmi/<device_name>/capdata), so that users can
dump capdata and include it in their reports.

Since `struct capdata01' is just an extension to `struct capdata00',
also convert the former to include the latter anonymously
(-fms-extensions, since v6.19). This is declared as a union in the
capdata01 struct, with both the anonymous declaration and as a named
member to avoid type casting when passing just the capdata00 struct
pointer.

Subject: [PATCH 1904/5214] platform: arm64 Use named initializers for struct
 i2c_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

While touching all these arrays, unify usage of whitespace in the list
terminator.

Subject: [PATCH 1906/5214] platform/x86: Move delayed work on system_dfl_wq
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the code enqueue work items using {queue|mod}_delayed_work(),
using system_wq, which will be deprecated soon and replaced by
system_percpu_wq.

   commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")

The function(s) mentioned earlier, end up calling __queue_delayed_work(),
which set a global timer that could fire anywhere, enqueuing the work
where the timer fired.

Unbound works could benefit from scheduler task placement, to optimize
performance and power consumption.

Since the workqueue work doesn't rely on per-cpu variables, there is no
obvious reason that justify the use of a per-cpu workqueue. So change
system_wq with system_dfl_wq so that the work may benefit from
scheduler task placement.

Subject: [PATCH 1907/5214] PCI: qcom: Disable ASPM L0s for SA8775P

Due to a hardware issue, L0s is not properly supported by the PCIe
controller on the SA8775p SoC. If enabled, the L0s to L0 transition
triggers below correctable AER errors and may also affect link stability:

  pcieport 0000:00:00.0: PME: Signaling with IRQ 332
  pcieport 0000:00:00.0: AER: enabled with IRQ 332
  pcieport 0000:00:00.0: AER: Correctable error message received from 0000:01:00.0
  pci 0000:01:00.0: PCIe Bus Error: severity=Correctable, type=Data Link Layer, (Transmitter ID)
  pci 0000:01:00.0:   device [17cb:1103] error status/mask=00001000/0000e000
  pci 0000:01:00.0:    [12] Timeout
  pcieport 0000:00:00.0: AER: Multiple Correctable error message received from 0000:01:00.0
  pcieport 0000:00:00.0: PCIe Bus Error: severity=Correctable, type=Data Link Layer, (Transmitter ID)
  pcieport 0000:00:00.0:   device [17cb:0115] error status/mask=00001000/0000e000
  pcieport 0000:00:00.0:    [12] Timeout

Hence, disable L0s for the SA8775p SoC to allow it to properly function
by sacrificing a little bit of power saving.

Subject: [PATCH 1909/5214] pinctrl: renesas: rzv2m: Use -ENOTSUPP instead of
 -EOPNOTSUPP

The pinctrl and GPIO core code make exceptions for the -ENOTSUPP error
code. One such example is gpio_set_config_with_argument_optional(), which
returns success when gpio_set_config_with_argument() returns -ENOTSUPP, but
reports failure for all other error codes.

Returning -EOPNOTSUPP from the pinctrl driver on the unsupported pinctrl
operation may lead to boot failures when pinctrl drivers implements
struct gpio_chip::set_config, the system uses GPIO hogs, and the
struct gpio_chip::set_config implementation returns -EOPNOTSUPP for the
unsupported operations.

Currently, the driver does not implement struct gpio_chip::set_config().
To avoid future failures, return -ENOTSUPP from
rzv2m_pinctrl_pinconf_set().

rzv2m_pinctrl_pinconf_group_get() is used when dumping pinctrl
configuration. pinconf_generic_dump_one(), which calls it, makes
exceptions for the -EINVAL and -ENOTSUPP error codes. The documentation
for struct pinconf_ops::pin_config_group_get states that it "should
return -ENOTSUPP and -EINVAL using the same rules as pin_config_get()".
The documentation for struct pinconf_ops::pin_config_get states:

"get the config of a certain pin, if the requested config is not available
on this controller this should return -ENOTSUPP and if it is available but
disabled it should return -EINVAL".

Return -ENOTSUPP for the unsupported pinctrl operation.

Subject: [PATCH 1912/5214] KVM: x86: Use fls() instead of ffs() for rmaps
 histogram bucketing

The kvm_mmu_rmaps_stat_show() function implements a logarithmic histogram
to collect statistics on the distribution of pte_list_count sizes. However,
it currently uses ffs() (Find First Set), which looks for the least
significant set bit.

Using ffs() leads to severe statistical distortion for any count that is
not a power of two. For example, if a rmap has a pte_list_count of 6
(binary 0110), ffs(6) returns 2, forcing this entry to be erroneously
counted towards the bucket representing a count of 2. In contrast, it
conceptually belongs to the bucket spanning the 4 to 7 range.

Replace ffs() with fls() (Find Last Set) to correctly identify the most
significant set bit (effectively computing floor(log2(count)) + 1). This Ensure
that intermediate counts are correctly categorized into their appropriate
power-of-two order-of-magnitude buckets rather than being severely
under-reported.

Subject: [PATCH 1919/5214] media: i2c: cvs: Add driver of Intel Computer
 Vision Sensing Controller(CVS)

Add driver for Intel Computer Vision Sensing (CVS) devices found on
Intel Luna Lake (LNL), Panther Lake (PTL), and Arrow Lake (ARL)
platforms.

The CVS device acts as a V4L2 sub-device bridge that manages CSI-2
link ownership between the host (Linux) and firmware for camera
sensors. It provides:

- Query the device status via sysfs interface
- CSI-2 link ownership arbitration between host and CVS firmware
- MIPI CSI-2 configuration management
- Privacy LED control coordination
- Power management integration with runtime PM

The driver consists of two main components:
  core.c: Core driver with probe, command transport, and power management
  v4l2.c: V4L2 sub-device and media framework integration

Hardware Interface:
- I2C for command/control communication with device firmware
- GPIO signals for ownership handshaking (request/response)
- Optional reset and wake interrupt for full-capability variants
- Integration with Intel IPU via ipu_bridge

The driver supports two hardware capability levels:
- Light capability: Basic GPIO-based ownership (2 GPIOs)
- Full capability: Enhanced with reset control and wake IRQ (4 GPIOs)

Device-specific quirks are handled via a quirk table to accommodate
variations across different CVS implementations (Lattice, Synaptics).

In addition to I2C-based operation, the driver supports platform
device instantiation for systems where CVS is exposed without I2C
transport, falling back to GPIO-only ownership control.

The CVS driver integrates with the IPU bridge for automatic device
discovery via ACPI on supported platforms.

PCI device IDs for Intel IPU7 (0x645d, shared by MTL and LNL) and
IPU7.5 (0xb05d, shared by ARL and PTL) are included in the
driver-local icvs_pci_tbl lookup table, enabling CVS to locate these
IPU variants without modifying the shared ipu6-pci-table header.

A PM runtime device link is established between IPU (consumer) and CVS
(supplier) so that the PM framework automatically resumes CVS before
IPU begins streaming, triggering cvs_runtime_resume() to claim CSI-2
link ownership. Ownership is released via cvs_runtime_suspend() after
the autosuspend delay.

Subject: [PATCH 1920/5214] media: pci: intel: Add CVS support for IPU bridge
 driver

CVS is located between IPU device and sensors and is available in
existing commercial platforms from multiple OEMs. The connection
information between them in firmware is not enough to build a V4L2
connection graph. This patch parses the connection properties from the
SSDB buffer in DSDT and builds the connection using software nodes.

From the IPU bridge point of view, CVS is just like IVSC.

Subject: [PATCH 1921/5214] media: ti: j721e-csi2rx: Minor cleanup of loop
 variables

Replace open-coded `i--; for (; i >= 0; i--)` patterns with the
idiomatic `while (i--)` in the error unwind paths of
csi_async_notifier_complete() and ti_csi2rx_probe().

Also scope loop variables directly in the for statement instead of
declaring them at the top of the function in ti_csi2rx_suspend(),
ti_csi2rx_resume() and ti_csi2rx_remove(). Change the type to
unsigned int in the first two to match csi->num_ctx.

Subject: [PATCH 1922/5214] media: ti: j721e-csi2rx: Fix error handling for
 media_entity_remote_source_pad_unique()

The media_entity_remote_source_pad_unique() function returns an error
pointer on failure, not NULL. Fix the check to use IS_ERR() and return
PTR_ERR() to correctly handle allocation failures.

Fixes: 982135c0eac6 ("media: ti: j721e-csi2rx: add a subdev for the core device")

+-------------------------------------
+
+The RK3588 Video Capture (VICAP) unit features a digital video port and six
+MIPI CSI-2 capture interfaces that can receive video data independently.
+The DVP accepts parallel video data, BT.656 and BT.1120.
+Since the BT.1120 protocol may feature more than one stream, the RK3588 VICAP
+DVP features four DMA engines that can capture different streams.
+Similarly, the RK3588 VICAP MIPI CSI-2 receivers feature four DMA engines each
+to handle different Virtual Channels (VCs).
+
+The rkcif driver represents this hardware variant by exposing the following
+V4L2 subdevices:
+
+* dw-mipi-csi2rx fdd30000.csi: MIPI CSI-2 receiver connected to MIPI DPHY0
+* dw-mipi-csi2rx fdd50000.csi: MIPI CSI-2 receiver connected to MIPI DPHY1

Subject: [PATCH 1925/5214] media: rockchip: rkcif: add support for rk3588
 vicap mipi capture

The RK3588 Video Capture (VICAP) unit features a Digital Video Port (DVP)
and six MIPI CSI-2 capture interfaces. Add initial support for this variant
to the rkcif driver and enable the MIPI CSI-2 capture interfaces.

Subject: [PATCH 1926/5214] x86/topology: Add missing struct declaration and
 attribute dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The prototypes for get_topology_cpu_type_name() and
get_topology_cpu_type() take a pointer to struct cpuinfo_x86, but
asm/topology.h neither includes nor forward-declares the structure.
Including asm/topology.h, directly or indirectly, without including
asm/processor.h triggers a warning:

    ./arch/x86/include/asm/topology.h:159:47: error: ‘struct cpuinfo_x86’
    declared inside parameter list will not be visible outside of this
    definition or declaration [-Werror]
    159 | const char *get_topology_cpu_type_name(struct cpuinfo_x86 *c);
        |                                               ^~~~~~~~~~~

Since only a pointer is needed, add a forward declaration of struct
cpuinfo_x86.

Additionally, sysctl_sched_itmt_enabled is declared in asm/topology.h with
the __read_mostly attribute, but the header does not include linux/cache.h.
This causes a build failure when including asm/topology.h but not linux/
cache.h:

     ./arch/x86/include/asm/topology.h:264:27: error: expected ‘=’, ‘,’,
     ‘;’, ‘asm’ or ‘__attribute__’ before ‘sysctl_sched_itmt_enabled’
     264 | extern bool __read_mostly sysctl_sched_itmt_enabled;
         |                           ^~~~~~~~~~~~~~~~~~~~~~~~~

Include the required header.

Subject: [PATCH 1927/5214] x86/acpi: Add functions to setup and access the
 wakeup mailbox

Systems that describe hardware using DeviceTree graphs may enumerate and
implement the wakeup mailbox as defined in the ACPI specification but do
not otherwise depend on ACPI. Expose functions to setup and access the
location of the wakeup mailbox from outside ACPI code.

The function acpi_setup_mp_wakeup_mailbox() stores the physical address of
the mailbox and updates the wakeup_secondary_cpu_64() APIC callback.

The function acpi_madt_multiproc_wakeup_mailbox() returns a pointer to the
mailbox.

Subject: [PATCH 1928/5214] dt-bindings: reserved-memory: Wakeup Mailbox for
 Intel processors

Add DeviceTree bindings to enumerate the wakeup mailbox used in platform
firmware for Intel processors.

x86 platforms commonly boot secondary CPUs using an INIT assert, de-assert
followed by Start-Up IPI messages. The wakeup mailbox can be used when this
mechanism is unavailable.

The wakeup mailbox offers more control to the operating system to boot
secondary CPUs than a spin-table. It allows the reuse of the same wakeup
vector for all CPUs while maintaining control over which CPUs to boot and
when. While it is possible to achieve the same level of control using a
spin-table, it would require specifying a separate `cpu-release-addr` for
each secondary CPU.

The operation and structure of the mailbox are described in the
Multiprocessor Wakeup Structure defined in the ACPI specification. Note
that this structure does not specify how to publish the mailbox to the
operating system (ACPI-based platform firmware uses a separate table). No
ACPI table is needed in DeviceTree-based firmware to enumerate the mailbox.

Nodes that want to refer to the reserved memory usually define
a `memory-region` property. /cpus/cpu* nodes would want to refer to the
mailbox, but they do not have such property defined in the DeviceTree
specification. Moreover, it would imply that there is a memory region per
CPU. Instead, add a `compatible` property that the operating system can use
to discover the mailbox.

Subject: [PATCH 1929/5214] x86/dt: Parse the Wakeup Mailbox for Intel
 processors

The Wakeup Mailbox is a mechanism to boot secondary CPUs on systems that do
not want or cannot use the INIT + StartUp IPI messages.

The platform firmware is expected to implement the mailbox as described in
the Multiprocessor Wakeup Structure of the ACPI specification. It is also
expected to publish the mailbox to the operating system as described in the
corresponding DeviceTree schema that accompanies the documentation of the
Linux kernel.

Reuse the existing functionality to set the memory location of the mailbox
and update the wakeup_secondary_cpu_64() APIC callback. Make this
functionality available to DeviceTree-based systems by making CONFIG_X86_
MAILBOX_WAKEUP depend on either CONFIG_OF or CONFIG_ACPI_MADT_WAKEUP.

do_boot_cpu() uses wakeup_secondary_cpu_64() when set. It will be set if a
wakeup mailbox is enumerated via an ACPI table or a DeviceTree node. For
cases in which this behavior is not desired, this APIC callback can be
updated later during boot using platform-specific hooks.

Subject: [PATCH 1930/5214] x86/hyperv/vtl: Set real_mode_header in
 hv_vtl_init_platform()

Hyper-V VTL clears x86_platform.realmode_{init(), reserve()} in
hv_vtl_init_platform() whereas it sets real_mode_header later in
hv_vtl_early_init(). There is no need to deal with the settings of real
mode memory in two places. Also, both functions are called much earlier
than x86_platform.realmode_init() (via an early_initcall), where the
real_mode_header is needed.

Set real_mode_header in hv_vtl_init_platform() to keep all code dealing
with memory for the real mode trampoline in one place. Besides making the
code more readable, it prepares it for a subsequent changeset in which the
behavior needs to change to support Hyper-V VTL guests in a TDX
environment.

Subject: [PATCH 1931/5214] x86/realmode: Make the location of the trampoline
 configurable

x86 CPUs boot in real mode. This mode uses a 1MB address space. The
trampoline must reside below this 1MB memory boundary.

There are platforms in which the firmware boots the secondary CPUs,
switches them to long mode and transfers control to the kernel. An example
of such a mechanism is the ACPI Multiprocessor Wakeup Structure.

In this scenario there is no restriction on locating the trampoline under
1MB memory. Moreover, certain platforms (for example, Hyper-V VTL guests)
may not have memory available for allocation below 1MB.

Add a new member to struct x86_init_resources to specify the upper bound
for the location of the trampoline memory. Preserve the default upper bound
of 1MB to conserve the current behavior.

Subject: [PATCH 1932/5214] x86/hyperv/vtl: Setup the 64-bit trampoline for TDX
 guests

The hypervisor is an untrusted entity for TDX guests. It cannot be used
to boot secondary CPUs - neither via hypercalls nor the INIT assert,
de-assert, plus Start-Up IPI messages.

Instead, the platform virtual firmware boots the secondary CPUs and
puts them in a state to transfer control to the kernel. This mechanism uses
the wakeup mailbox described in the Multiprocessor Wakeup Structure of the
ACPI specification. The entry point to the kernel is trampoline_start64.

Allocate and setup the trampoline using the default x86_platform callbacks.

The platform firmware configures the secondary CPUs in long mode. It is no
longer necessary to locate the trampoline under 1MB memory. After handoff
from firmware, the trampoline code switches briefly to 32-bit addressing
mode, which has an addressing limit of 4GB. Set the upper bound of the
trampoline memory accordingly.

While testing perf with an updated Debian experimental cross compiler
(gcc version 14.2.0 (Debian 14.2.0-13)) this started failing:

version 16.1.1 20260515 (Red Hat 16.1.1-2)) it ends up with:

  cc1: all warnings being treated as errors

So the way to satisfy both compilers is to also add a (u64) cast to
arg7.

Subject: [PATCH 1937/5214] dt-bindings: spmi: glymur-spmi-pmic-arb: Add
 compatible for Qualcomm Hawi SoC

The PMIC arbiter in the Qualcomm Hawi SoC is version v8.5, which
introduces parity and CRC checks for data received from the PMIC,
as well as NACK checks for command sequences except for read.
All other features in PMIC arbiter remain the same as the one in
the Qualcomm Glymur SoC, with the only differences being some
additional error status checks.

Therefore, add a string for "qcom,hawi-spmi-pmic-arb" as a compatible
entry for "qcom,glymur-spmi-pmic-arb".

 v8.5

PMIC arbiter v8.5 is an extension of PMIC arbiter v8 that updated
the definition of the channel status register bit fields. Add support
to handle this difference.

Subject: [PATCH 1942/5214] net/9p: fix infinite loop in p9_client_rpc on fatal
 signal

When p9_client_rpc() is called with type P9_TFLUSH and the transport
has no peer (e.g. fd transport backed by pipes with no 9p server),
a fatal signal causes an infinite loop:

  again:
	err = io_wait_event_killable(req->wq, ...)
	/* SIGKILL wakes the task, returns -ERESTARTSYS */

	if (err == -ERESTARTSYS && c->status == Connected &&
		type == P9_TFLUSH) {
		sigpending = 1;
		clear_thread_flag(TIF_SIGPENDING);
		goto again;
	}

clear_thread_flag() clears TIF_SIGPENDING before jumping back to
io_wait_event_killable(). signal_pending_state() checks TIF_SIGPENDING,
finds it zero, and the task goes to sleep again. The task can only wake
on the next signal delivery that calls signal_wake_up() and sets
TIF_SIGPENDING again. When that happens the loop repeats, clears
TIF_SIGPENDING, and sleeps again indefinitely.

This is triggered in practice by coredump_wait(): when a thread in a
multi-threaded process causes a coredump (e.g. via SIGSYS from Syscall
User Dispatch), coredump_wait() sends SIGKILL to all other threads and
waits for them to call mm_release(). If one of those threads is blocked
in p9_client_rpc() over an fd transport with no peer, it enters the
P9_TFLUSH loop and never calls mm_release(), so coredump_wait() stalls
forever:

 </TASK>

Fix: check fatal_signal_pending() before clearing TIF_SIGPENDING in the
P9_TFLUSH retry loop. At that point TIF_SIGPENDING is still set, so
fatal_signal_pending() works correctly. If a fatal signal is pending,
jump to recalc_sigpending to restore TIF_SIGPENDING and return
-ERESTARTSYS to the caller.

The same defect is present in stable kernels back to 5.4. On those
kernels the infinite loop is broken earlier by a second SIGKILL from
the parent process (e.g. kill_and_wait() retrying after a timeout),
resulting in a zombie process and a shutdown delay rather than a
permanent D-state hang, but the underlying flaw is the same.

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Subject: [PATCH 1943/5214] ring-buffer: Skip invalid sub-buffers when
 validating persistent ring buffer

Skip invalid sub-buffers when validating the persistent ring buffer
instead of discarding the entire ring buffer. Only skipped buffers
are invalidated (cleared).

If the cache data in memory fails to be synchronized during a reboot,
the persistent ring buffer may become partially corrupted, but other
sub-buffers may still contain readable event data. Only discard the
subbuffers that are found to be corrupted.

Subject: [PATCH 1944/5214] ring-buffer: Skip invalid sub-buffers when
 rewinding persistent ring buffer

Skip invalid sub-buffers when rewinding the persistent ring buffer
instead of stopping the rewinding the ring buffer. The skipped
buffers are cleared.

To ensure the rewinding stops at the unused page, this also clears
buffer_data_page::time_stamp when tracing resets the buffer. This
allows us to identify unused pages and empty pages.

Subject: [PATCH 1945/5214] ring-buffer: Add persistent ring buffer
 invalid-page inject test

Add a self-corrupting test for the persistent ring buffer.

This will inject an erroneous value to some sub-buffer pages (where
the index is even or multiples of 5) in the persistent ring buffer
when the kernel panics, and checks whether the number of detected
invalid pages and the total entry_bytes are the same as the recorded
values after reboot.

This ensures that the kernel can correctly recover a partially
corrupted persistent ring buffer after a reboot or panic.

The test only runs on the persistent ring buffer whose name is
"ptracingtest". The user has to fill it with events before a
kernel panic.

To run the test, enable CONFIG_RING_BUFFER_PERSISTENT_INJECT
and add the following kernel cmdline:

 reserve_mem=20M:2M:trace trace_instance=ptracingtest^traceoff@trace
 panic=1

Run the following commands after the 1st boot:

 cd /sys/kernel/tracing/instances/ptracingtest
 echo 1 > tracing_on
 echo 1 > events/enable
 sleep 3
 echo c > /proc/sysrq-trigger

After panic message, the kernel will reboot and run the verification
on the persistent ring buffer, e.g.

 Ring buffer meta [2] invalid buffer page detected
 Ring buffer meta [2] is from previous boot! (318 pages discarded)
 Ring buffer testing [2] invalid pages: PASSED (318/318)
 Ring buffer testing [2] entry_bytes: PASSED (1300476/1300476)

This is useful for understanding the current status of the
persistent ring buffer. (Note that this file is shown
only for persistent ring buffer and its backup instance)

 validation

Cleanup rb_meta_validate_events() function to make it easier to read.
This includes the following cleanups:
 - Introduce rb_validatation_state to hold working variables in
   validation.
 - Move repleated validation state updates into rb_validate_buffer().
 - Move reader_page injection code outside of rb_meta_validate_events().

Subject: [PATCH 1948/5214] ring-buffer: Cleanup buffer_data_page related code

Code cleanup related to buffer_data_page for readability,
which includes:
- Introduce rb_data_page_commit() and rb_data_page_size()
- Use 'dpage' for buffer_data_page, instead of 'bpage' because
  'bpage' is used for buffer_page.

Subject: [PATCH 1949/5214] ring-buffer: Have dropped subbuffers be persistent
 across reboots

When the persistent ring buffer detects a corrupted subbuffer, it will
zero its size and report dropped pages in the dmesg, then it continues
normally.

But if a reboot happens without clearing or restarting tracing on the
persistent ring buffer, the next boot will show no pages are dropped.

If the persistent ring buffer is still the same, then it should still
report dropped pages so the user knows that the buffer has missing events.

Add the RB_MISSED_EVENTS flag to the commit value of the subbuffer so that
the next boot will still show that pages were dropped.

Subject: [PATCH 1950/5214] ring-buffer: Show persistent buffer dropped events
 in trace file

When the persistent ring buffer is validated on boot up, if a subbuffer is
deemed invalid, it resets the buffer and continues. Currently, these lost
events are not shown in the trace file output.

Have the trace iterator look for subbuffers that have the RB_MISSED_EVENTS
set and set the iter->missed_events flag when it is detected. This will
then have the trace file shows "LOST EVENTS" when it reads across a
subbuffer that was corrupted and invalidated.

For example:

 <...>-1016    [005] ...1.  6230.660403: preempt_disable: caller=__mod_memcg_state+0x1c8/0x200 parent=__mod_memcg_state+0x1c8/0x200

Subject: [PATCH 1951/5214] ring-buffer: Show persistent buffer dropped events

like the trace file does.

Subject: [PATCH 1952/5214] selftests/mm: respect build verbosity settings for
 32/64-bit targets

Patch series "selftests/mm: clean up build output and verbosity", v3.

Currently, the build process for the mm selftests is unnecessarily noisy.

First, it leaks raw compiler errors during the liburing feature probe if
the headers are missing, which is confusing since the build system already
handles this gracefully with a clear warning.

Second, the specific 32-bit and 64-bit compilation targets ignore the
standard kbuild verbosity settings, always printing their full compiler
commands even during a default quiet build.


This patch (of 2):

The 32-bit and 64-bit compilation rules invoke $(CC) directly, bypassing
the $(Q) quiet prefix and $(call msg,...) helper used by the rest of the
selftests build system.  This causes these rules to always print the full
compiler command line, even when V=0 (the default).

Wrap the commands with $(Q) and $(call msg,CC,,$@) to match the convention
used by lib.mk, so that quiet and verbose builds behave consistently
across all targets.

Subject: [PATCH 1953/5214] selftests/mm: suppress compiler error in liburing
 check

When building the mm selftests on a system without liburing development
headers, check_config.sh leaks a raw compiler error:

  /tmp/tmp.kIIOIqwe3n.c:2:10: fatal error: liburing.h: No such file or directory
      2 | #include <liburing.h>
        |          ^~~~~~~~~~~~

Since this is an expected failure during the configuration probe,
redirect the compiler output to /dev/null to hide it.

And the build system prints a clear warning when this occurs:

  Warning: missing liburing support. Some tests will be skipped.

Because the user is properly notified about the missing dependency, the
raw compiler error is redundant and only confuse users.

Additionally, update the Makefile to use $(Q) and $(call msg,...) for the
check_config.sh execution.  This aligns the probe with standard kbuild
output formatting, providing a clean "CHK" message instead of printing the
raw command during the build.

Subject: [PATCH 1954/5214] mm/page_alloc: replace kernel_init_pages() with
 batch page clearing

When init_on_alloc is enabled, kernel_init_pages() clears every page one
at a time via clear_highpage_kasan_tagged(), which incurs per-page
kmap_local_page()/kunmap_local() overhead and prevents the architecture
clearing primitive from operating on contiguous ranges.

Introduce clear_highpages_kasan_tagged() as a static batch clearing helper
in page_alloc.c that calls clear_pages() for the full contiguous range on
!HIGHMEM systems, bypassing the per-page kmap overhead and allowing a
single invocation of the arch clearing primitive across the entire
allocation.  The HIGHMEM path falls back to per-page clearing since those
pages require kmap.

Replace kernel_init_pages() with direct calls to the new helper, as it
becomes a trivial wrapper.

Allocating 8192 x 2MB HugeTLB pages (16GB) with init_on_alloc=1:

  Before: 0.445s
  After:  0.166s  (-62.7%, 2.68x faster)

Kernel time (sys) reduction per workload with init_on_alloc=1:

Subject: [PATCH 1955/5214] Revert "tmpfs: don't enable large folios if not
 supported"

This reverts commit 5a90c155defa684f3a21f68c3f8e40c056e6114c.

Currently, when shmem mounts are initialized, they only use 'sbinfo->huge'
to determine whether the shmem mount supports large folios.  However, for
anonymous shmem, whether it supports large folios can be dynamically
configured via sysfs interfaces, so setting or not setting
mapping_set_large_folios() during initialization cannot accurately reflect
whether anonymous shmem actually supports large folios, which has already
caused some confusion[1].

Moreover, for tmpfs mounts, relying on 'sbinfo->huge' cannot keep the
mapping_set_large_folios() setting consistent across all mappings in the
entire tmpfs mount.  In other words, under the same tmpfs mount, after
remount, we might end up with some mappings supporting large folios
(calling mapping_set_large_folios()) while others don't.

After some investigation, I found that the write performance regression
addressed by commit 5a90c155defa has already been fixed by the following
commit 665575cff098b ("filemap: move prefaulting out of hot write path").
See the following test data:

Base:
dd if=/dev/zero of=/mnt/tmpfs/test bs=400K count=10485 (3.2 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/test bs=800K count=5242 (3.2 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/test bs=1600K count=2621 (3.1 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/test bs=2200K count=1906 (3.0 GB/s )
dd if=/dev/zero of=/mnt/tmpfs/test bs=3000K count=1398 (3.0 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/test bs=4500K count=932 (3.1 GB/s)

Base + revert 5a90c155defa:
dd if=/dev/zero of=/mnt/tmpfs/test bs=400K count=10485 (3.3 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/test bs=800K count=5242 (3.3 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/test bs=1600K count=2621 (3.2 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/test bs=2200K count=1906 (3.1 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/testbs=3000K count=1398 (3.0 GB/s)
dd if=/dev/zero of=/mnt/tmpfs/test bs=4500K count=932 (3.1 GB/s)

The data is basically consistent with minor fluctuation noise. So we can now
safely revert commit 5a90c155defa to set mapping_set_large_folios() for all
shmem mounts unconditionally.

Subject: [PATCH 1958/5214] mm/vmscan: add balance_pgdat begin/end tracepoints

Vmscan has six main reclaim entry points: try_to_free_pages() for
direct reclaim, try_to_free_mem_cgroup_pages() for memcg reclaim,
mem_cgroup_shrink_node() for memcg soft limit reclaim, node_reclaim()
for node reclaim, shrink_all_memory() for hibernation reclaim, and
balance_pgdat() for kswapd reclaim.

All of them, except for shrink_all_memory() and balance_pgdat(),
already have begin/end tracepoints.  This makes it harder to trace
which reclaim path is responsible for memory reclaim activity, because
kswapd reclaim cannot be identified as cleanly as other reclaim entry
points, even though it is the main background reclaim path under memory
pressure.  There may be no need to trace shrink_all_memory() as it is
primarily used during hibernation.  So this patch adds the missing
tracepoint pair for balance_pgdat().

The begin tracepoint records the node id, requested reclaim order, and
the requested classzone bound (highest_zoneidx).  The end tracepoint
records the node id, the reclaim order that balance_pgdat() finished
with, the requested classzone bound, and nr_reclaimed.  Together, they
show the requested reclaim order and classzone bound, whether reclaim
fell back to a lower order, and how much reclaim work was done.

The end tracepoint also records highest_zoneidx even though it does not
change within a balance_pgdat() invocation.  This keeps the end event
self-contained, so users can analyze reclaim results directly from end
events without depending on begin/end correlation, which is less
convenient when tracing is filtered or records are dropped.  It also
makes it straightforward to relate nr_reclaimed and the final reclaim
order to the requested classzone bound.

Subject: [PATCH 1959/5214] mm/page_alloc: optimize free_contig_range()

Patch series "mm: Free contiguous order-0 pages efficiently", v6.

A recent change to vmalloc caused some performance benchmark regressions
(see [1]).  I'm attempting to fix that (and at the same time significantly
improve beyond the baseline) by freeing a contiguous set of order-0 pages
as a batch.

At the same time I observed that free_contig_range() was essentially doing
the same thing as vfree() so I've fixed it there too.  While at it,
optimize the __free_contig_frozen_range() as well.

Check that the contiguous range falls in the same section.  If they aren't
enabled, the if conditions get optimized out by the compiler as
memdesc_section() returns 0.  See num_pages_contiguous() for more details
about it.


This patch (of 3):

Decompose the range of order-0 pages to be freed into the set of largest
possible power-of-2 size and aligned chunks and free them to the pcp or
buddy.  This improves on the previous approach which freed each order-0
page individually in a loop.  Testing shows performance to be improved by
more than 10x in some cases.

Since each page is order-0, we must decrement each page's reference count
individually and only consider the page for freeing as part of a high
order chunk if the reference count goes to zero.  Additionally
free_pages_prepare() must be called for each individual order-0 page too,
so that the struct page state and global accounting state can be
appropriately managed.  But once this is done, the resulting high order
chunks can be freed as a unit to the pcp or buddy.

This significantly speeds up the free operation but also has the side
benefit that high order blocks are added to the pcp instead of each page
ending up on the pcp order-0 list; memory remains more readily available
in high orders.

vmalloc will shortly become a user of this new optimized
free_contig_range() since it aggressively allocates high order
non-compound pages, but then calls split_page() to end up with contiguous
order-0 pages.  These can now be freed much more efficiently.

The execution time of the following function was measured in a server
class arm64 machine:

static int page_alloc_high_order_test(void)
{
	unsigned int order = HPAGE_PMD_ORDER;
	struct page *page;
	int i;

	for (i = 0; i < 100000; i++) {
		page = alloc_pages(GFP_KERNEL, order);
		if (!page)
			return -1;
		split_page(page, order);
		free_contig_range(page_to_pfn(page), 1UL << order);
	}

	return 0;
}

Subject: [PATCH 1960/5214] vmalloc: optimize vfree with free_pages_bulk()

Whenever vmalloc allocates high order pages (e.g.  for a huge mapping) it
must immediately split_page() to order-0 so that it remains compatible
with users that want to access the underlying struct page.  Commit
a06157804399 ("mm/vmalloc: request large order pages from buddy
allocator") recently made it much more likely for vmalloc to allocate high
order pages which are subsequently split to order-0.

Unfortunately this had the side effect of causing performance regressions
for tight vmalloc/vfree loops (e.g.  test_vmalloc.ko benchmarks).  See
Closes: tag.  This happens because the high order pages must be gotten
from the buddy but then because they are split to order-0, when they are
freed they are freed to the order-0 pcp.  Previously allocation was for
order-0 pages so they were recycled from the pcp.

It would be preferable if when vmalloc allocates an (e.g.) order-3 page
that it also frees that order-3 page to the order-3 pcp, then the
regression could be removed.

So let's do exactly that; update stats separately first as coalescing is
hard to do correctly without complexity.  Use free_pages_bulk() which uses
the new __free_contig_range() API to batch-free contiguous ranges of pfns.
This not only removes the regression, but significantly improves
performance of vfree beyond the baseline.

A selection of test_vmalloc benchmarks running on arm64 server class
system.  mm-new is the baseline.  Commit a06157804399 ("mm/vmalloc:
request large order pages from buddy allocator") was added in v6.19-rc1
where we see regressions.  Then with this change performance is much
better.  (>0 is faster, <0 is slower, (R)/(I) = statistically significant

Subject: [PATCH 1961/5214] mm/page_alloc: optimize
 __free_contig_frozen_range()

Apply the same batch-freeing optimization from free_contig_range() to the
frozen page path.  The previous __free_contig_frozen_range() freed each
order-0 page individually via free_frozen_pages(), which is slow for the
same reason the old free_contig_range() was: each page goes to the order-0
pcp list rather than being coalesced into higher-order blocks.

Rewrite __free_contig_frozen_range() to call free_pages_prepare() for each
order-0 page, then batch the prepared pages into the largest possible
power-of-2 aligned chunks via free_prepared_contig_range().  If
free_pages_prepare() fails (e.g.  HWPoison, bad page) the page is
deliberately not freed; it should not be returned to the allocator.

I've tested CMA through debugfs.  The test allocates 16384 pages per
allocation for several iterations.  There is 3.5x improvement.

Subject: [PATCH 1962/5214] mm/gup: cleanup pgtable entry accessors

PMD and PUD entries revalidation has the same semantics as PTE entry
revalidation.  Convert the remaining direct entry dereferences to the
corresponding accessors.

The PTE validation in gup_fast_pte_range() is inconsistent with the prior
value acquisition in the sense that it drops the lockless access
semantics.

Use the lockless accessor not only for the PTE, but also for the PMD
validation, which is likewise inconsistent with the prior value
acquisition in gup_fast_pmd_range().

Subject: [PATCH 1963/5214] mm/memory: update stale locking comments for fault
 handlers

Update the comments for wp_page_copy(), do_wp_page(), do_swap_page(),
do_anonymous_page(), __do_fault(), do_fault(), handle_pte_fault(),
__handle_mm_fault(), and handle_mm_fault() to concisely clarify that they
can be entered holding either the mmap_lock or the VMA lock, and that the
lock may be released upon returning VM_FAULT_RETRY.

Additionally, make the following corrections:
- In do_anonymous_page(), correct the outdated claim that the function
  is entered with the PTE "mapped but not yet locked". Since
  handle_pte_fault() unmaps the empty PTE before routing to
  do_pte_missing(), the comment now correctly states it is entered
  with the PTE unmapped and unlocked.
- In __do_fault(), update the stale reference from __lock_page_retry()
  to __folio_lock_or_retry().

Subject: [PATCH 1964/5214] mm/damon/core: make charge_addr_from aware of
 end-address exclusivity

DAMON region end address is exclusive one, but charge_addr_from is
assigned assuming the end address is inclusive.  As a result, DAMOS action
to next up to min_region_sz memory can be skipped.  This is quite
negligible user impact.  But, the bug is a bug that can be very simply
fixed.  Fix the wrong assignment to respect the exclusiveness of the
address.

The issue was discovered [1] by Sashiko.

Subject: [PATCH 1965/5214] mm/damon: add node_eligible_mem_bp goal metric

Background and Motivation
=========================

In heterogeneous memory systems, controlling memory distribution across
NUMA nodes is essential for performance optimization.  This patch enables
system-wide page distribution with target-state goals such as "maintain
60% of scheme-eligible memory on DRAM" using PA-mode DAMON schemes.

Rather than using absolute thresholds, this metric tracks the ratio of
memory that matches each scheme's access pattern filters on a target node,
enabling the quota system to automatically adjust migration aggressiveness
to maintain the desired distribution.

What This Metric Measures
=========================

node_eligible_mem_bp:
    scheme_eligible_bytes_on_node / total_scheme_eligible_bytes * 10000

Two-Scheme Setup for Hot Page Distribution
==========================================

For maintaining 60% of hot memory on DRAM (node 0) and 40% on CXL
(node 1):

    PULL scheme: migrate_hot to node 0
      goal: node_eligible_mem_bp, nid=0, target=6000
      addr filter: node 1 address range (only migrate FROM CXL)
      "Move hot pages to DRAM if less than 60% of hot data is in DRAM"

    PUSH scheme: migrate_hot to node 1
      goal: node_eligible_mem_bp, nid=1, target=4000
      addr filter: node 0 address range (only migrate FROM DRAM)
      "Move hot pages to CXL if less than 40% of hot data is in CXL"

Each scheme independently measures its own eligible memory and adjusts its
quota to achieve its target ratio.  The schemes work in concert through
DAMON's unified monitoring context, with the quota autotuner balancing
their relative aggressiveness.

Implementation Details
======================

The implementation adds a new quota goal metric type
DAMOS_QUOTA_NODE_ELIGIBLE_MEM_BP to the existing DAMOS quota goal
framework.  When this metric is configured for a scheme:

1. During each quota adjustment cycle, damos_get_node_eligible_mem_bp()
   is called to calculate the current memory distribution.

2. The function iterates through all regions that match the scheme's
   access pattern (via __damos_valid_target()) and calculates:
   - Total eligible bytes across all nodes
   - Eligible bytes specifically on the target node (goal->nid)

3. For each eligible region, damos_calc_eligible_bytes() walks through
   the physical address range, using damon_get_folio() to look up
   each folio and determine its NUMA node via folio_nid().

4. Large folios are handled by calculating the exact overlap between
   the region boundaries and folio boundaries, ensuring accurate
   byte counts even when regions partially span folios.

5. The ratio (node_eligible / total_eligible * 10000) is returned
   as basis points, which the quota autotuner uses to adjust the
   scheme's effective quota size (esz).

The implementation requires CONFIG_DAMON_PADDR since damon_get_folio()
is only available for physical address space monitoring.

Testing Results
===============

Functionally tested on a two-node heterogeneous memory system with DRAM
(node 0) and CXL memory (node 1).  A PUSH+PULL scheme configuration using
migrate_hot actions was used to reach a target hot memory ratio between
the two tiers.

With the TEMPORAL tuner, the system converges quickly to the target
distribution.  The tuner drives esz to maximum when under goal and to zero
once the goal is met, forming a simple on/off feedback loop that
stabilizes at the desired ratio.

With the CONSIST tuner, the scheme still converges but more slowly, as it
migrates and then throttles itself based on quota feedback.  The time to
reach the goal varies depending on workload intensity.

Note: This metric works with both TEMPORAL and CONSIST goal tuners.

Subject: [PATCH 1966/5214] mm/damon/core: handle <min_region_sz remaining
 quota as empty

Patch series "mm/damon: introduce DAMOS failed region quota charge ratio".

Let users set different DAMOS quota charge ratios for DAMOS action failed
regions, for deterministic and consistent DAMOS action progress.

Common Reports: Unexpectedly Slow DAMOS
=======================================

One common issue report that we get from DAMON users is that DAMOS action
applying progress speed is sometimes much slower than expected.  And one
common root cause is that the DAMOS quota is exceeded by the action
applying failed memory regions.

For example, a group of users tried to run DAMOS-based proactive memory
reclamation (DAMON_RECLAIM) with 100 MiB per second DAMOS quota.  They ran
it on a system having no active workload which means all memory of the
system is cold.  The expectation was that the system will show 100 MiB per
second reclamation until (nearly) all memory is reclaimed.  But what they
found is that the speed is quite inconsistent and sometimes it becomes
very slower than the expectation, sometimes even no reclamation at all for
about tens of seconds.  The upper limit of the speed (100 MiB per second)
was being kept as expected, though.

By monitoring the qt_exceeds (number of DAMOS quota exceed events) DAMOS
stat, we found DAMOS quota is always exceeded when the speed is slow.  By
monitoring sz_tried and sz_applied (the total amount of DAMOS action tried
memory and succeeded memory) DAMOS stats together, we found the
reclamation attempts nearly always failed when the speed is slow.

DAMOS quota charges DAMOS action tried regions regardless of the
successfulness of the try.  Hence in the example reported case, there was
unreclaimable memory spread around the system memory.  Sometimes nearly
100 MiB of memory that DAMOS tried to reclaim in the given quota interval
was reclaimable, and therefore showed nearly 100 MiB per second speed.
Sometimes nearly 99 MiB of memory that DAMOS was trying to reclaim in the
given quota interval was unreclaimable, and therefore showing only about 1
MiB per second reclaim speed.

We explained it is an expected behavior of the feature rather than a bug,
as DAMOS quota is there for only the upper-limit of the speed.  The users
agreed and later reported a huge win from the adoption of DAMON_RECLAIM on
their products.

It is Not a Bug but a Feature; But...
=====================================

So nothing is broken.  DAMOS quota is working as intended, as the upper
limit of the speed.  It also provides its behavior observability via DAMOS
stat.  In the real world production environment that runs long term active
workloads and matters stability, the speed sometimes being slow is not a
real problem.

But, the non-deterministic behavior is sometimes annoying, especially in
lab environments.  Even in a realistic production environment, when there
is a huge amount of DAMOS action unapplicable memory, the speed could be
problematically slow.  Let's suppose a virtual machines provider that
setup 99% of the host memory as hugetlb pages that cannot be reclaimed, to
give it to virtual machines.  Also, when aim-oriented DAMOS auto-tuning is
applied, this could also make the internal feedback loop confused.

The intention of the current behavior was that trying DAMOS action to
regions would anyway impose some overhead, and therefore somehow be
charged.  But in the real world, the overhead for failed action is much
lighter than successful action.  Charging those at the same ratio may be
unfair, or at least suboptimum in some environments.

DAMOS Action Failed Region Quota Charge Ratio
=============================================

Let users set the charge ratio for the action-failed memory, for more
optimal and deterministic use of DAMOS.  It allows users to specify the
numerator and the denominator of the ratio for flexible setup.  For
example, let's suppose the numerator and the denominator are set to 1 and
4,096, respectively.  The ratio is 1 / 4,096.  A DAMOS scheme action is
applied to 5 GiB memory.  For 1 GiB of the memory, the action is
succeeded.  For the rest (4 GiB), the action is failed.  Then, only 1 GiB
and 1 MiB quota is charged.

The optimal charge ratio will depend on the use case and system/workload.
I'd recommend starting from setting the nominator as 1 and the denominator
as PAGE_SIZE and tune based on the results, because many DAMOS actions are
applied at page level.

Tests
=====

I tested this feature in the steps below.

1. Allocate 50% of system memory and mlock() it using a test program.
2. Fill up the page cache to exhaust nearly all free memory.
3. Start DAMON-based proactive reclamation with 100 MiB/second DAMOS
   hard-quota.  Auto-tune the DAMOS soft-quota under the hard-quota for
   achieving 40% free memory of the system with 'temporal' tuner.

For step 1, I run a simple C program that is written by Gemini.  It is
quite straightforward, so I'm not sharing the code here.

For step 2, I use dd command like below:

   dd if=/dev/zero of=foo bs=1M count=$50_percent_of_system_memory

For step 3, I use the latest version of DAMON user-space tool (damo) like
below.

    sudo damo start --damos_action pageout \
            ` # Do the pageout only up to 100 MiB per second ` \
            --damos_quota_space 100M --damos_quota_interval 1s \
            ` # Auto-tune the quota below the hard quota aiming` \
            ` # 40% free memory of the node 0 ` \
            ` # (entire node of the test system)` \
            --damos_quota_goal node_mem_free_bp 40% 0 \
            ` # use temporal tuner, which is easy to understnd ` \
            --damos_quota_goal_tuner temporal

As expected, the progress of the reclamation is not consistent, because
the quota is exceeded for the failed reclamation of the unreclaimable
memory.

I do this again, but with the failed region charge ratio feature.  For
this, the above 'damo' command is used, after appending command line
option for setup of the charge ratio like below.  Note that the option was
added to 'damo' after v3.1.9.

    sudo ./damo start --damos_action pageout \
            [...]
            ` # quota-charge only 1/4096 for pageout-failed regions ` \
            --damos_quota_fail_charge_ratio 1 4096

The progress of the reclamation was nearly 100 MiB per second until the
goal was achieved, meeting the expectation.

Patches Sequence
================

The first two patches make preparational changes.  Patch 1 updates fully
charged quota check to handle <min_region_sz remaining quota, which will
be able to exist after this series is applied.  Patch 2 merges regions
after applying schemes is done as long as it is ok to do, since regions
split operations for quota could happen much more frequently under a
corner case that this series will make available.

Patch 3 implements the feature and exposes it via DAMON core API.  Patch 4
implements DAMON sysfs ABI for the feature.  Three following patches (5-7)
document the feature and ABI on design, usage, and ABI documents,
respectively.  Four patches for testing of the new feature follow.  Patch
8 implements a kunit test for the feature.  Patches 9 and 10 extend DAMON
selftest helpers for DAMON sysfs control and internal state dumping for
adding a new selftest for the feature.  Patch 11 extends existing DAMON
sysfs interface selftest to test the new feature using the extended helper
scripts.


This patch (of 11):

Less than min_region_sz remaining quota effectively means the quota is
fully charged.  In other words, no remaining quota.  This is because DAMOS
actions are applied in the region granularity, and each region should have
min_region_sz or larger size.  However the existing fully charged quota
check, which is also used for setting charge_target_from and
charge_addr_from of the quota, is not aware of the case.  For the reason,
charge_target_from and charge_addr_from of the quota will not be updated
in the case.  This can result in DAMOS action being applied more
frequently to a specific area of the memory.

The case is unreal because quota charging is also made in the region
granularity.  It could be changed in future, though.  Actually, the
following commit will make the change, by allowing users to set arbitrary
quota charging ratio for action-failed regions.  To be prepared for the
change, update the fully charged quota checks to treat having less than
min_region_sz remaining quota as fully charged.

Subject: [PATCH 1967/5214] mm/damon/core: merge regions after applying DAMOS
 schemes

damos_apply_scheme() could split the given region if applying the scheme's
action to the entire region can result in violating the quota-set upper
limit.  Keeping regions that are created by such split operations is
unnecessary overhead.

The overhead would be negligible in the common case because such split
operations could happen only up to the number of installed schemes per
scheme apply interval.  The following commit could make the impact larger,
though.  The following commit will allow the action-failed region to be
charged in a different ratio.  If both the ratio and the remaining quota
is quite small while the region to apply the scheme is quite large and the
action is nearly always failing, a high number of split operations could
happen.

Remove the unnecessary overhead by merging regions after applying schemes
is done for each region.  The merge operation is made only if it will not
lose monitoring information and keep min_nr_regions constraint.  In the
worst case, the max_nr_regions could still be violated until the next
per-aggregation interval merge operation is made.

Subject: [PATCH 1968/5214] mm/damon/core: introduce failed region quota charge
 ratio

DAMOS quota is charged to all DAMOS action application attempted memory,
regardless of how much of the memory the action was successful and failed.
This makes understanding quota behavior without DAMOS stat but only with
end level metrics (e.g., increased amount of free memory for DAMOS_PAGEOUT
action) difficult.  Also, charging action-failed memory same as
action-successful memory is somewhat unfair, as successful action
application will induce more overhead in most cases.

Introduce DAMON core API for setting the charge ratio for such
action-failed memory.  It allows API callers to specify the ratio in a
flexible way, by setting the numerator and the denominator.

+
+Action-failed Memory Charging Ratio
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+DAMOS action to a given region can fail for some subsets of the memory of the
+region.  For example, if the action is ``pageout`` and the region has some
+unreclaimable pages, applying the action to the pages will fail.  The amount of
+system resource that is taken for such failed action applications is usually
+different from that for successful action applications.  For such cases, users
+can set different charging ratio for such failed memory.  The ratio can be
+specified using ``fail_charge_num`` and ``fail_charge_denom`` parameters.  The
+two parameters represent the numerator and denominator of the ratio.  The
+feature is enabled only if ``fail_charge_denom`` is not zero.
+
+For example, let's suppose a DAMOS action is applied to a region of 1,000 MiB
+size.  The action is successfully applied to only 700 MiB of the region.
+``fail_charge_num`` and ``fail_charge_denom`` are set to ``1`` and ``1024``,
+respectively.  Then only 700 MiB and 300 KiB of size (``700 MiB + 300 MiB * 1 /
+1024``) will be charged.

Subject: [PATCH 1977/5214] selftests/cgroup: skip test_zswap if zswap is
 globally disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Patch series "selftests/cgroup: improve zswap tests robustness and support
large page sizes", v7.

This patchset aims to fix various spurious failures and improve the
overall robustness of the cgroup zswap selftests.

The primary motivation is to make the tests compatible with architectures
that use non-4K page sizes (such as 64K on ppc64le and arm64).  Currently,
the tests rely heavily on hardcoded 4K page sizes and fixed memory limits.
On 64K page size systems, these hardcoded values lead to sub-page
granularity accesses, incorrect page count calculations, and insufficient
memory pressure to trigger zswap writeback, ultimately causing the tests
to fail.

Additionally, this series addresses OOM kills occurring in
test_swapin_nozswap by dynamically scaling memory limits, and prevents
spurious test failures when zswap is built into the kernel but globally
disabled.


This patch (of 8):

test_zswap currently only checks whether zswap is present by testing
/sys/module/zswap.  This misses the runtime global state exposed in
/sys/module/zswap/parameters/enabled.

When zswap is built/loaded but globally disabled, the zswap cgroup
selftests run in an invalid environment and may fail spuriously.

Check the runtime enabled state before running the tests:
  - skip if zswap is not configured,
  - fail if the enabled knob cannot be read,
  - skip if zswap is globally disabled.

Also print a hint in the skip message on how to enable zswap.

Subject: [PATCH 1978/5214] selftests/cgroup: avoid OOM in test_swapin_nozswap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

test_swapin_nozswap can hit OOM before reaching its assertions on some
setups.  The test currently sets memory.max=8M and then allocates/reads
32M with memory.zswap.max=0, which may over-constrain reclaim and kill the
workload process.

Replace hardcoded sizes with PAGE_SIZE-based values:
  - control_allocation_size = PAGE_SIZE * 512
  - memory.max = control_allocation_size * 3 / 4
  - minimum expected swap = control_allocation_size / 4

This keeps the test pressure model intact (allocate/read beyond memory.max
to force swap-in/out) while making it more robust across different
environments.

The test intent is unchanged: confirm that swapping occurs while zswap remains
unused when memory.zswap.max=0.

Subject: [PATCH 1979/5214] selftests/cgroup: use runtime page size for zswpin
 check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

test_zswapin compares memory.stat:zswpin (counted in pages) against a byte
threshold converted with PAGE_SIZE.  In cgroup selftests, PAGE_SIZE is
hardcoded to 4096, which makes the conversion wrong on systems with non-4K
base pages (e.g.  64K).

As a result, the test requires too many pages to pass and fails spuriously
even when zswap is working.

Use sysconf(_SC_PAGESIZE) for the zswpin threshold conversion so the check
matches the actual system page size.

Subject: [PATCH 1980/5214] selftests/cgroup: rename PAGE_SIZE to BUF_SIZE in
 cgroup_util
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cgroup utility code defines a local PAGE_SIZE macro hardcoded to 4096,
which is used primarily as a generic buffer size for reading cgroup and
proc files.  This naming is misleading because the value has nothing to do
with the actual page size of the system.  On architectures with larger
pages (e.g., 64K on arm64 or ppc64), the name suggests a relationship that
does not exist.  Additionally, the name can shadow or conflict with
PAGE_SIZE definitions from system headers, leading to confusion or subtle
bugs.

To resolve this, rename the macro to BUF_SIZE to accurately reflect its
purpose as a general I/O buffer size.

Furthermore, test_memcontrol currently relies on this hardcoded 4K value
to stride through memory and trigger page faults.  Update this logic to
use the actual system page size dynamically.  This micro-optimizes the
memory faulting process by ensuring it iterates correctly and efficiently
based on the underlying architecture's true page size.  (This part from
Waiman)

Subject: [PATCH 1981/5214] selftests/cgroup: replace hardcoded page size
 values in test_zswap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

test_zswap uses hardcoded values of 4095 and 4096 throughout as page
stride and page size, which are only correct on systems with a 4K page
size.  On architectures with larger pages (e.g., 64K on arm64 or ppc64),
these constants cause memory to be touched at sub-page granularity,
leading to inefficient access patterns and incorrect page count
calculations, which can cause test failures.

Replace all hardcoded 4095 and 4096 values with a global pagesize variable
initialized from sysconf(_SC_PAGESIZE) at startup, and remove the
redundant local sysconf() calls scattered across individual functions.  No
functional change on 4K page size systems.

Subject: [PATCH 1982/5214] selftest/cgroup: fix zswap
 test_no_invasive_cgroup_shrink on large pagesize system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

test_no_invasive_cgroup_shrink sets up two cgroups: wb_group, which is
expected to trigger zswap writeback, and a control group (renamed to
zw_group), which should only have pages sitting in zswap without any
writeback.

There are two problems with the current test:

1) The data patterns are reversed. wb_group uses allocate_bytes(), which
   writes only a single byte per page — trivially compressible,
   especially by zstd — so compressed pages fit within zswap.max and
   writeback is never triggered. Meanwhile, the control group uses
   getrandom() to produce hard-to-compress data, but it is the group
   that does *not* need writeback.

2) The test uses fixed sizes (10K zswap.max, 10MB allocation) that are
   too small on systems with large PAGE_SIZE (e.g. 64K), failing to
   build enough memory pressure to trigger writeback reliably.

Fix both issues by:
  - Swapping the data patterns: fill wb_group pages with partially
    random data (getrandom for page_size/4 bytes) to resist compression
    and trigger writeback, and fill zw_group pages with simple repeated
    data to stay compressed in zswap.
  - Making all size parameters PAGE_SIZE-aware: set allocation size to
    PAGE_SIZE * 1024, memory.zswap.max to PAGE_SIZE, and memory.max to
    allocation_size / 2 for both cgroups.
  - Allocating memory inline instead of via cg_run() so the pages
    remain resident throughout the test.

reclaiming clean file pages (binary, libc, linker, etc.) over swapping
anonymous pages.  With only 64 pages of anonymous memory, the reclaim
target can be largely or entirely satisfied by dropping file pages,
resulting in very few or zero anonymous pages being pushed into zswap.

This causes zswap_usage to be extremely small or zero, making
zswap_usage/4 insufficient to create meaningful writeback pressure.  The
test then fails because no writeback is triggered.

On 4K page size systems this is not an issue because 4M covers 1024
pages, and file pages are a small fraction of the reclaim target.

Fix this by:
- Always allocating 1024 pages regardless of page size. This ensures
  enough anonymous pages to reliably populate zswap and trigger
  writeback, while keeping the original 4M allocation on 4K systems.
- Setting zswap.max to zswap_usage/4 instead of zswap_usage/2 to
  create stronger writeback pressure, ensuring reclaim reliably
  triggers writeback even on large page size systems.

Subject: [PATCH 1984/5214] selftests/cgroup: test_zswap: wait for asynchronous
 writeback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

zswap writeback is asynchronous, but test_zswap.c checks writeback
counters immediately after reclaim/trigger paths.  On some platforms (e.g.
ppc64le), this can race with background writeback and cause spurious
failures even when behavior is correct.

Add wait_for_writeback() to poll get_cg_wb_count() with a bounded
timeout, and use it in:

  test_zswap_writeback_one() when writeback is expected
  test_no_invasive_cgroup_shrink() for the wb_group check

This keeps the original before/after assertion style while making the
tests robust against writeback completion latency.

No test behavior change, selftest stability improvement only.

Remove the odd VM_WARN_ON_FOLIO(!folio, folio) usage and replace it with a
simpler VM_WARN_ON_ONCE(!folio) check.

Drop the redundant VM_WARN_ON_ONCE(!pmd_none(*pmdp) &&
!is_huge_zero_pmd(*pmdp)).

Refactor the PMD checks, making the control flow clearer and avoiding
duplicate condition checks.

Subject: [PATCH 1986/5214] mm/sparse: remove unnecessary NULL check before
 allocating mem_section

Commit 850ed20539a4 ("mm: move array mem_section init code out of
memory_present()") moved mem_section allocation logic into
memblocks_present().

Before that move, memory_present() could be called multiple times, so
unlikely() matched the common case, where most calls found mem_section
already allocated.

After that move, memblocks_present() is called exactly once from
sparse_init().  Under CONFIG_SPARSEMEM_EXTREME, mem_section is always NULL
when it is called.

So remove unnecessary NULL check before allocating mem_section.  No
functional change.

Subject: [PATCH 1988/5214] mm: fix mmap errno value when MAP_DROPPABLE is not
 supported

Patch series "fix MAP_DROPPABLE not supported errno", v4.

Mark Brown reported seeing a regression in -next on 32 bit arm with the
mlock selftests.  Before exiting and marking the tests failed, the
following message was logged after an attempt to create a MAP_DROPPABLE
mapping:

Bail out! mmap error: Unknown error 524

It turns out error 524 is ENOTSUPP which is an error that userspace is not
supposed to see, but it indicates in this instance that MAP_DROPPABLE is
not supported.

The first patch changes the errno returned to EOPNOTSUPP.  The second
patch is a second version of a prior patch to introduce selftests to
verify locking behavior with droppable mappings with the additional change
to skip the tests when MAP_DROPPABLE is not supported.  The third patch
fixes the MAP_DROPPABLE selftest so that it is run by the framework and
skips if MAP_DROPPABLE is not supported.


This patch (of 3):

On configs where MAP_DROPPABLE is not supported (currently any 32-bit
config except for PPC32), mmap fails with errno set to ENOTSUPP.  However,
ENOTSUPP is not a standard error value that userspace knows about.  The
acceptable userspace-visible errno to use is EOPNOTSUPP.  checkpatch.pl
has a warning to this effect.

Subject: [PATCH 1990/5214] selftests/mm: run the MAP_DROPPABLE selftest

The test was not being run by the selftest framework so it was never
noticed that it would fail with an assertion failure on configs without
support for MAP_DROPPABLE.  Update the test so that it is skipped instead
when MAP_DROPPABLE is not supported, and add it to the mmap category so
that the test is run by the framework.

Subject: [PATCH 1991/5214] mm/page_owner: fix %pGp format specifier argument
 type

The %pGp format specifier expects an argument of type 'unsigned long *',
but page->flags is now of type 'memdesc_flags_t' (a struct containing an
unsigned long member 'f') after the introduction of memdesc_flags_t.

Fix the type mismatch by passing &page->flags.f instead of &page->flags,
which matches the expected type.

Subject: [PATCH 1993/5214] mm/sparse: remove sparse buffer pre-allocation
 mechanism

Commit 9bdac9142407 ("sparsemem: Put mem map for one node together.")
introduced a mechanism to pre-allocate a large memory block to hold all
memmaps for a NUMA node upfront.

However, the original commit message did not clearly state the actual
benefits or the necessity of explicitly pre-allocating a single chunk for
all memmap areas of a given node.

One of the concerns about removing this pre-allocation is that the
subsequent per-section memmap allocations could become scattered around,
and might turn too many memory blocks/sections into an "un-offlinable"
state.  However, tests show that even without the explicit node-wide
pre-allocation, memblock still allocates memory closely and back-to-back.
When tracing vmemmap_set_pmd allocations, the physical chunks allocated by
memblock are strictly adjacent to each other in a single contiguous
physical range (mapped top-down).  Because they are packed tightly
together naturally, they will at most consume or pollute the exact same
number of memory blocks as the explicit pre-allocation did.

Another concern is the boot performance impact of calling memmap_alloc()
multiple times compared to one large node-wide allocation.  Tests on a
256GB VM showed that memmap allocation time increased from 199,555 ns to
741,292 ns.  Even though it is 3.7x slower, on a 1TB machine, the entire
memory allocation time would only take a few milliseconds.  This boot
performance difference is completely negligible.

Since no negative impact on memory offlining behavior or noticeable boot
performance regression was found, this patch proposes removing the
explicit node-wide memmap pre-allocation mechanism to reduce the
maintenance burden.

Subject: [PATCH 1996/5214] mm: huge_memory: use sysfs_match_string() in
 defrag_store()

Patch series "mm: huge_memory: clean up defrag sysfs with shared", v2.

Refactor defrag_store() and defrag_show() to use shared data tables
instead of duplicated if/else chains.

Patch 1 introduces an enum defrag_mode, a defrag_mode_strings[] table, and
a defrag_flags[] mapping array, then rewrites defrag_store() to use
sysfs_match_string() with a loop over defrag_flags[].

Patch 2 refactors defrag_show() to use the same arrays, replacing its
hardcoded if/else chain of test_bit() calls and string literals.

This follows the same pattern applied to anon_enabled_store() in commit
522dfb4ba71f ("mm: huge_memory: refactor anon_enabled_store() with
change_anon_orders()").


This patch (of 2):

Replace the if/else chain of sysfs_streq() calls in defrag_store() with
sysfs_match_string() and a defrag_mode_strings[] table.

Introduce enum defrag_mode and defrag_flags[] array mapping each mode to
its corresponding transparent_hugepage_flag.  The store function now loops
over defrag_flags[], setting the bit for the selected mode and clearing
the others.  When mode is DEFRAG_NEVER (index 4), no index in the
4-element defrag_flags[] matches, so all flags are cleared.

Note that the enum ordering (always, defer, defer+madvise, madvise, never)
differs from the original if/else chain order in defrag_store() (always,
defer+madvise, defer, madvise, never).  This is intentional to match the
display order used by defrag_show().

This is a follow-up cleanup to commit 522dfb4ba71f ("mm: huge_memory:
refactor anon_enabled_store() with change_anon_orders()") which applied
the same sysfs_match_string() pattern to anon_enabled_store().

Subject: [PATCH 1997/5214] mm: huge_memory: refactor defrag_show() to use
 defrag_flags[]

Replace the hardcoded if/else chain of test_bit() calls and string
literals in defrag_show() with a loop over defrag_flags[] and
defrag_mode_strings[] arrays introduced in the previous commit.

This makes defrag_show() consistent with defrag_store() and eliminates the
duplicated mode name strings.

Subject: [PATCH 1998/5214] mm/vmpressure: skip socket pressure for costly
 order reclaim

When reclaim is triggered by high order allocations on a fragmented
system, vmpressure() can report poor reclaim efficiency even though the
system has plenty of free memory.  This is because many pages are scanned,
but few are found to actually reclaim - the pages are actively in use and
don't need to be freed.  The resulting scan:reclaim ratio causes
vmpressure() to assert socket pressure, throttling TCP throughput
unnecessarily.

Costly order allocations (above PAGE_ALLOC_COSTLY_ORDER) rely heavily on
compaction to succeed, so poor reclaim efficiency at these orders does not
necessarily indicate memory pressure.  The kernel already treats this
order as the boundary where reclaim is no longer expected to succeed and
compaction may take over.

Make vmpressure() order-aware through an additional parameter sourced from
scan_control at existing call sites.  Socket pressure is now only asserted
when order <= PAGE_ALLOC_COSTLY_ORDER.

Memcg reclaim is unaffected since try_to_free_mem_cgroup_pages() always
uses order 0, which passes the filter unconditionally.  Similarly,
vmpressure_prio() now passes order 0 internally when calling vmpressure(),
ensuring critical pressure from low reclaim priority is not suppressed by
the order filter.

The patch was motivated by a case of impacted net throughput in
production.  On one affected host, the memory state at the time showed
~15GB available, zero cgroup pressure, and the following buddyinfo state:

Order FreePages
0:    133,970
1:    29,230
2:    17,351
3:    18,984
7+:   0

Using bpf, it was found that 94% of vmpressure calls on this host were
from order-7 kswapd reclaim.

TCP minimum recv window is rcv_ssthresh:19712.

Before patch:
723 out of 3,843 (19%) TCP connections stuck at minimum recv window

After live-patching and ~30min elapsed:
0 out of 3,470 TCP connections stuck at minimum recv window

 GET_PAGE_MAX_RETRY_NUM

Replace the hardcoded magic number 3 in get_any_page() with the existing
GET_PAGE_MAX_RETRY_NUM macro for code consistency and maintainability.

This change has no functional impact, only improves code readability and
unifies the retry limit configuration.

Subject: [PATCH 2002/5214] mm/thp: dead code cleanup in Kconfig

There is already an 'if TRANSPARENT_HUGEPAGE' condition wrapping several
config options e.g.  'READ_ONLY_THP_FOR_FS', making the 'depends on'
statement for each of these a duplicate dependency (dead code).

I propose leaving the outer 'if TRANSPARENT_HUGEPAGE...endif' and removing
the individual 'depends on TRANSPARENT_HUGEPAGE' statement from each
option.

This dead code was found by kconfirm, a static analysis tool for Kconfig.

Subject: [PATCH 2003/5214] mm, page_alloc: reintroduce page allocation stall
 warning

Previously, we had warnings when a single page allocation took longer than
reasonably expected.  This was introduced in commit 63f53dea0c98 ("mm:
warn about allocations which stall for too long").

The warning was subsequently reverted in commit 400e22499dd9 ("mm: don't
warn about allocations which stall for too long") because it was possible
to generate memory pressure that would effectively stall further progress
through printk execution.

Page allocation stalls in excess of 10 seconds are always useful to debug
because they can result in severe userspace unresponsiveness.  Adding this
artifact can be used to correlate with userspace going out to lunch and to
understand the state of memory at the time.

There should be a reasonable expectation that this warning will never
trigger given it is very passive, it will only be emitted when a page
allocation takes longer than 10 seconds.  If it does trigger, this reveals
an issue that should be fixed: a single page allocation should never loop
for more than 10 seconds without oom killing to make memory available.

Unlike the original implementation, this implementation only reports
stalls once for the system every 10 seconds.  Otherwise, many concurrent
reclaimers could spam the kernel log unnecessarily.  Stalls are only
reported when calling into direct reclaim.

Subject: [PATCH 2004/5214] mm/lruvec: preemptively free dead folios during
 lru_add drain

Of all observable lruvec lock contention in our fleet, we find that ~24%
occurs when dead folios are present in lru_add batches at drain time.
This is wasteful in the sense that the folio is added to the LRU just to
be immediately removed via folios_put_refs(), incurring two unnecessary
lock acquisitions.

Eliminate this overhead by preemptively cleaning up dead folios before
they make it into the LRU.  Use folio_ref_freeze() to filter folios whose
only remaining refcount is the batch ref.  When dead folios are found,
move them off the add batch and onto a temporary batch to be freed.

PG_active may be set on a batched folio as well as PG_unevictable (via
migration path).  Since filtered folios bypass the normal lru_add()
cleanup, both flags must be cleared before freeing.

During A/B testing on one of our prod instagram workloads (high-frequency
short-lived requests), the patch intercepted almost all dead folios before
they entered the LRU.  Data collected using the mm_lru_insertion
tracepoint shows the effectiveness of the patch:

Per-host LRU add averages at 95% CPU load
(60 hosts each side, 3 x 60s intervals)

            dead folios/min  total folios/min   dead %
unpatched:        1,297,785        19,341,986  6.7097%
patched:                 14        19,039,996  0.0001%

Within this workload, we save ~2.6M lock acquisitions per minute per host
as a result.

System-wide memory stats improved on the patched side also at 95% CPU load:
 - direct reclaim scanning reduced 7%
 - allocation stalls reduced 5.2%
 - compaction stalls reduced 12.3%
 - page frees reduced 4.9%

No regressions were observed in requests served per second or request tail
latency (p99).  Both metrics showed directional improvement at higher CPU
utilization (comparing 85% to 95%).

Note that tests were performed using classic LRU.

Subject: [PATCH 2005/5214] mm/hugetlb: fix hugetlb cgroup rsvd charge/uncharge
 mismatch

In alloc_hugetlb_folio(), a single h_cg pointer is used for both the rsvd
and non-rsvd hugetlb cgroup charges.  When map_chg is set,
hugetlb_cgroup_charge_cgroup_rsvd() stores the charged cgroup in h_cg, but
the immediately following hugetlb_cgroup_charge_cgroup() overwrites h_cg
with the non-rsvd cgroup pointer.

As a result, hugetlb_cgroup_commit_charge_rsvd() stores the wrong
(non-rsvd) cgroup pointer into the folio's rsvd slot.

When the folio is later freed, free_huge_folio() unconditionally calls
both hugetlb_cgroup_uncharge_folio() and
hugetlb_cgroup_uncharge_folio_rsvd().  The rsvd uncharge reads back the
wrong cgroup from the folio and decrements a counter that was never
charged for that cgroup, causing a page_counter underflow:

  page_counter underflow: -512 nr_pages=512
  WARNING: mm/page_counter.c:61 at page_counter_cancel

Fix this by introducing a separate h_cg_rsvd pointer exclusively for the
rsvd charge path, keeping the rsvd and non-rsvd charges fully independent
through their charge, commit, and error uncharge paths.

Subject: [PATCH 2006/5214] drm/managed: use special gfp_t format specifier

Patch series "treewide: fixup gfp_t printks", v2.

Use vprintf()'s special gfp_t conversion in a few places.


This patch (of 3):

%pGg produces nice readable output and decouples the format string from
the size of gfp_t.

Subject: [PATCH 2009/5214] dax/kmem: account for partial discontiguous
 resource upon removal

When dev_dax_kmem_probe() partially succeeds (at least one range is
mapped) but a subsequent range fails request_mem_region() or
add_memory_driver_managed(), the probe silently continues, ultimately
returning success, but with the corresponding range resource NULL'ed out.

dev_dax_kmem_remove() iterates over all dax_device ranges regardless of if
the underlying resource exists.  When remove_memory() is called later, it
returns 0 because the memory was never added which causes
dev_dax_kmem_remove() to incorrectly assume the (nonexistent) resource can
be removed and attempts cleanup on a NULL pointer.

Fix this by skipping these ranges altogether, noting that these cases are
considered success, such that the cleanup is still reached when all
actually-added ranges are successfully removed.

Subject: [PATCH 2010/5214] selftests/mm: simplify byte pattern checking in
 mremap_test

The original version of mremap_test (7df666253f26: "kselftests: vm: add
mremap tests") validated remapped contents byte-by-byte and printed a
mismatch index in case the bytes streams didn't match.  That was rather
inefficient, especially also if the test passed.

Later, commit 7033c6cc9620 ("selftests/mm: mremap_test: optimize execution
time from minutes to seconds using chunkwise memcmp") used memcmp() on
bigger chunks, to fallback to byte-wise scanning to detect the problematic
index only if it discovered a problem.

However, the implementation is overly complicated (e.g., get_sqrt() is
currently not optimal) and we don't really have to report the exact index:
whoever debugs the failing test can figure that out.

Let's simplify by just comparing both byte streams with memcmp() and not
detecting the exact failed index.

Subject: [PATCH 2011/5214] mm/sparse-vmemmap: fix vmemmap accounting underflow

Patch series "mm: Fix vmemmap optimization accounting and initialization",
v8.

The series fixes several bugs in vmemmap optimization, mainly around
incorrect page accounting and memmap initialization in DAX and memory
hotplug paths.  It also fixes pageblock migratetype initialization and
struct page initialization for ZONE_DEVICE compound pages.

Patches 1-4 fix vmemmap accounting issues.  Patch 1 fixes an accounting
underflow in the section activation failure path by moving vmemmap page
accounting into the lower-level allocation and freeing helpers.  Patch 2
fixes incorrect altmap passing in the memory hotplug error path.  Patch 3
passes pgmap through memory deactivation paths so the teardown side can
determine whether vmemmap optimization was in effect.  Patch 4 uses that
information to account the optimized DAX vmemmap size correctly.

Patches 5-6 fix initialization issues in mm/mm_init.  One makes sure all
pageblocks in ZONE_DEVICE compound pages get their migratetype
initialized.  The other fixes a case where DAX memory hotplug reuses an
unoptimized early-section memmap while compound_nr_pages() still assumes
vmemmap optimization, leaving tail struct pages uninitialized.


This patch (of 6):

In section_activate(), if populate_section_memmap() fails, the error
handling path calls section_deactivate() to roll back the state.  This
causes a vmemmap accounting imbalance.

Since commit c3576889d87b ("mm: fix accounting of memmap pages"), memmap
pages are accounted for only after populate_section_memmap() succeeds.
However, the failure path unconditionally calls section_deactivate(),
which decreases the vmemmap count.  Consequently, a failure in
populate_section_memmap() leads to an accounting underflow, incorrectly
reducing the system's tracked vmemmap usage.

Fix this more thoroughly by moving all accounting calls into the lower
level functions that actually perform the vmemmap allocation and freeing:

  - populate_section_memmap() accounts for newly allocated vmemmap pages -
depopulate_section_memmap() unaccounts when vmemmap is freed

This ensures proper accounting in all code paths, including error handling
and early section cases.

Subject: [PATCH 2012/5214] mm/memory_hotplug: fix incorrect altmap passing in
 error path

In create_altmaps_and_memory_blocks(), when arch_add_memory() succeeds
with memmap_on_memory enabled, the vmemmap pages are allocated from
params.altmap.  If create_memory_block_devices() subsequently fails, the
error path calls arch_remove_memory() with a NULL altmap instead of
params.altmap.

This is a bug that could lead to memory corruption.  Since altmap is NULL,
vmemmap_free() falls back to freeing the vmemmap pages into the system
buddy allocator via free_pages() instead of the altmap.
arch_remove_memory() then immediately destroys the physical linear mapping
for this memory.  This injects unowned pages into the buddy allocator,
causing machine checks or memory corruption if the system later attempts
to allocate and use those freed pages.

Fix this by passing params.altmap to arch_remove_memory() in the error
path.

Subject: [PATCH 2013/5214] mm/sparse-vmemmap: pass @pgmap argument to memory
 deactivation paths

Currently, the memory hot-remove call chain -- arch_remove_memory(),
__remove_pages(), sparse_remove_section() and section_deactivate() -- does
not carry the struct dev_pagemap pointer.  This prevents the lower levels
from knowing whether the section was originally populated with vmemmap
optimizations (e.g., DAX with vmemmap optimization enabled).

Without this information, we cannot call vmemmap_can_optimize() to
determine if the vmemmap pages were optimized.  As a result, the vmemmap
page accounting during teardown will mistakenly assume a non-optimized
allocation, leading to incorrect memmap statistics.

To lay the groundwork for fixing the vmemmap page accounting, we need to
pass the @pgmap pointer down to the deactivation location.  Plumb the
@pgmap argument through the APIs of arch_remove_memory(), __remove_pages()
and sparse_remove_section(), mirroring the corresponding *_activate()
paths.

Subject: [PATCH 2014/5214] mm/sparse-vmemmap: fix DAX vmemmap accounting with
 optimization

When vmemmap optimization is enabled for DAX, the nr_memmap_pages counter
in /proc/vmstat is incorrect.  The current code always accounts for the
full, non-optimized vmemmap size, but vmemmap optimization reduces the
actual number of vmemmap pages by reusing tail pages.  This causes the
system to overcount vmemmap usage, leading to inaccurate page statistics
in /proc/vmstat.

Fix this by introducing section_nr_vmemmap_pages(), which returns the
exact vmemmap page count for a given pfn range based on whether
optimization is in effect.

Subject: [PATCH 2015/5214] mm/mm_init: fix pageblock migratetype for
 ZONE_DEVICE compound pages

The memmap_init_zone_device() function only initializes the migratetype of
the first pageblock of a compound page.  If the compound page size exceeds
pageblock_nr_pages (e.g., 1GB hugepages with 2MB pageblocks), subsequent
pageblocks in the compound page remain uninitialized.

Move the migratetype initialization out of __init_zone_device_page() and
into a separate pageblock_migratetype_init_range() function.  This
iterates over the entire PFN range of the memory, ensuring that all
pageblocks are correctly initialized.

Also remove the stale confusing comment about MEMINIT_HOTPLUG above the
migratetype setting since it is an obsolete relic from commit 966cf44f637e
("mm: defer ZONE_DEVICE page initialization to the point where we init
pgmap") and no longer makes sense here.

Subject: [PATCH 2016/5214] mm/mm_init: fix uninitialized struct pages for
 ZONE_DEVICE

If DAX memory is hotplugged into an unoccupied subsection of an early
section, section_activate() reuses the unoptimized boot memmap.  However,
compound_nr_pages() still assumes that vmemmap optimization is in effect
and initializes only the reduced number of struct pages.  As a result, the
remaining tail struct pages are left uninitialized, which can later lead
to unexpected behavior or crashes.

Fix this by treating early sections as unoptimized when calculating how
many struct pages to initialize.

Subject: [PATCH 2017/5214] mm/damon/ops-common: optimize damon_hot_score()
 using ilog2()

Patch series "mm/damon: repost non-hotfix reviewed patches in damon/next
tree", v2.

The first patch from Liew Rui Yan add a minor performance optimization
using ilog2() instead of inefficient manual implementation of the
functionality.

The second patch from Cheng-Han Wu fixes a minor typo:
s/parametrs/parameters/.

The third patch from Liew Rui Yan make commit_inputs operation of
DAMON_RECLAIM and DAMON_LRU_SORT synchronous to improve the user
experience.

The fourth patch from Asier Gutierrez adds a new DAMOS action,
DAMOS_COLLAPSE for deterministic DAMOS-based access-aware THP system.


This patch (of 4):

The current implementation of damon_hot_score() uses a manual for-loop to
calculate the value of 'age_in_log'.  This can be efficiently replaced by
ilog2(), which is semantically more appropriate for calculating the
logarithmic value of age.

In a simulated-kernel-module performance test with 10,000,000 iterations,
this optimization showed a significant reduction in latency (average
latency reduced from ~12ns to ~1ns).

Test results from the simulated-kernel-module:

Subject: [PATCH 2019/5214] mm/damon: add synchronous commit for commit_inputs

Problem
=======
Writing invalid parameters to sysfs followed by 'commit_inputs=Y' fails
silently (no error returned to shell), because the validation happens
asynchronously in the kdamond.

Solution
========
To fix this, the commit_inputs_store() callback now uses damon_call() to
synchronously commit parameters in the kdamond thread's safe context.
This ensures that validation errors are returned immediately to
userspace, following the pattern used by DAMON_SYSFS.

Changes
=======
1. Added commit_inputs_store() and commit_inputs_fn() to commit
   synchronously.
2. Removed handle_commit_inputs().

This change is motivated from another discussion [1].

Subject: [PATCH 2020/5214] mm/damon: support MADV_COLLAPSE via DAMOS_COLLAPSE
 scheme action

This patch set introces a new action:  DAMOS_COLLAPSE.

For DAMOS_HUGEPAGE and DAMOS_NOHUGEPAGE to work, khugepaged should be
working, since it relies on hugepage_madvise to add a new slot.  This slot
should be picked up by khugepaged and eventually collapse (or not, if we
are using DAMOS_NOHUGEPAGE) the pages.  If THP is not enabled, khugepaged
will not be working, and therefore no collapse will happen.

DAMOS_COLLAPSE eventually calls madvise_collapse, which will collapse the
address range synchronously.  In cases where there is a large VMA
(databases, for example), DAMOS_COLLAPSE allows us to collapse only the
hot region, and not the entire VMA.

This new action may be required to support autotuning with hugepage
as a goal[1].

Benchmarks:

MySQL
=====

Tests were performed in an ARM physical server with MariaDB 10.5 and
sysbench. Read only benchmark was perform with gaussian row hitting,
which follows a normal distribution.

T m, D h: THP set to madvise, DAMON action set to hugepage
T n, D c: THP set to never, DAMON action set to collapse

Memory consumption. Lower is better.

Performance counter

I got the number of L1 D/I TLB accesses and the number a D/I TLB
accesses that triggered a page walk. I divided the second by the
first to get the percentage of page walkes per TLB access. The
lower the better.

=========

- We can see that DAMOS "hugepage" action works only when THP is set
  to madvise. "collapse" action works even when THP is set to never.
- Performance for "collapse" action is slightly lower than "hugepage"
  action and THP madvise. This is due to the fact that collapases
  occur synchronously. With "hugepage" they may occur during page
  faults.
- Memory consumption is slighly lower for "collapse" than "hugepage"
  with THP madvise. This is due to the khugepage collapses all VMAs,
  while "collapse" action only collapses the VMAs in the hot region.
- There is an improvement in TLB utilization when collapse through
  "hugepage" or "collapse" actions are triggered. The amount of
  TLB misses is lower.
- "collapse" action is performance synchronously, which means that
  page collapses happen earlier and more rapidly. This can be
  useful or not, depending on the scenario.
- "hugepage" action may trigger a VMA split in some scenarios, since
  it needs to change the flag of the VMA to THP enabled. This may
  lead to additional overhead.

Collapse action just adds a new option to chose the correct system
balance.

Subject: [PATCH 2021/5214] sh: use folio_mapped() instead of page_mapped() in
 sh4_flush_cache_page()

Patch series "mm: remove page_mapped()".

While preparing my slides for an LSF/MM talk, I realized that I did not
yet remove page_mapped().

So let's do that.  In the BPF arena code it's unclear which memdesc we
would want to allocate in the future: certainly something with a refcount,
but likely none with a mapcount.  So let's just rely on the page refcount
instead to decide whether we want to try zapping the page from user page
tables.


This patch (of 3):

We already have the folio in our hands, so let's just use folio_mapped().

Subject: [PATCH 2022/5214] bpf: arena: use page_ref_count() instead of
 page_mapped() in arena_free_pages()

Pages that BPF arena code maps are allocated through
bpf_map_alloc_pages(), which does not allocate folios but pages.

In the future, pages will not have a mapcount, only folios will.
Converting the code to use folios and rely on folio_mapped() sounds like
the wrong approach.

Should BPF arena code allocate folios and use folio_mapped() here?  But
likely we would not want to use folios here longterm, as we don't really
need folio information.

Hard to tell.  But in the meantime, we can simply use the page refcount
instead, as a heuristic whether the page might be mapped to user space and
we would want to try zapping it, so we can get rid of page_mapped().

Page allocation will give us a page with a refcount of 1.  Any user space
mapping adds a page reference.  While there can be references from other
subsystems (e.g., GUP), in the common case for this test here relying on
the page count is good enough.

Subject: [PATCH 2024/5214] mm/madvise: reject invalid process_madvise() advice
 for zero-length vectors

process_madvise() used to validate the advice while walking each imported
iovec.  If the vector has zero total length, vector_madvise() does not
enter the loop and can return success without checking whether the advice
value is valid.

For a local mm, such as process_madvise(PIDFD_SELF, ...), the remote-only
process_madvise_remote_valid() check is skipped.  As a result, an invalid
advice can be reported as success when the vector has zero total length.
This differs from madvise(), which rejects an invalid advice before
returning success for a zero-length range.

Validate the generic madvise behavior at the syscall-facing entry points
before any vector walk.  In process_madvise(), do this before the
remote-only advice restriction so unsupported advice is rejected with the
same priority for local and remote mm.

Use an errno-returning helper for address/length validation, and handle
zero-length ranges explicitly at the call sites.  Requests with valid
advice and zero total length remain a noop and continue to return 0.  Add
a selftest that covers invalid advice with a zero-length iovec and an
empty vector, while also checking that a request with valid advice and
zero length still succeeds.

Subject: [PATCH 2025/5214] mm: limit filemap_fault readahead to VMA boundaries

When a file mapping covers a strict subset of a file, an access to the
mapping can trigger readahead of file pages outside the mapped region.
Readahead is meant to prefetch pages likely to be accessed soon, but these
pages aren't accessible via the same means, so it fair to say we don't
have a good indicator they'll be accessed soon.  Take an ELF file for
example: an access to the end of a program's read-only segment isn't a
sign that nearby file contents will be accessed next (they are likely to
be mapped discontiguously, or not at all).  The pressure from loading
these pages into the cache can evict more useful pages.

To improve the behavior, make three changes:

* Introduce a new readahead_control field, max_index, as a hard limit on
  the readahead. The existing file_ra_state->size can't be used as a
  limit, it is more of a hint and can be increased by various
  heuristics.
* Set readahead_control->max_index to the end of the VMA in all of the
  readahead paths that can be triggered from a fault on a file mapping
  (both "sync" and "async" readahead).
* Limit the read-around range start to the VMA's start.

Note that these changes only affect readahead triggered in the context of
a fault, they do not affect readahead triggered by read syscalls.  If a
user mixes the two types of accesses, the behavior is expected to be the
following: if a fault causes readahead and places a PG_readahead marker
and then a read(2) syscall hits the PG_readahead marker, the resulting
async readahead *will not* be limited to the VMA end.  Conversely, if a
read(2) syscall places a PG_readahead marker and then a fault hits the
marker, the async readahead *will* be limited to the VMA end.

There is an edge case that the above motivation glosses over: A single
file mapping might be backed by multiple VMAs.  For example, a whole file
could be mapped RW, then part of the mapping made RO using mprotect.  This
patch would hurt performance of a sequential faulted read of such a
mapping, the degree depending on how fragmented the VMAs are.  A usage
pattern like that is likely rare and already suffering from sub-optimal
performance because, e.g., the fragmented VMAs limit the fault-around, so
each VMA boundary in a sequential faulted read would cause a minor fault.
Still, this patch would make it worse.  See a previous discussion of this
topic at [1].

Tested by mapping and reading a small subset of a large file, then using
the cachestat syscall to verify the number of cached pages didn't exceed
the mapping size.

In practical scenarios, the effect depends on the specific file and usage.
Sometimes there is no effect at all, but, for some ELF files in Android,
we see ~20% fewer pages pulled into the cache.

A comprehensive performance evaluation hasn't been done, but, in addition
to the anecdontal memory savings mentioned above, a benchmark was run with
fio 3.38, showing neutral looking results:

Subject: [PATCH 2026/5214] mm/damon/core: introduce damon_ctx->paused

Patch series "mm/damon: let DAMON be paused and resumed", v2.

DAMON utilizes a few mechanisms that enhance itself over time.  Adaptive
regions adjustment, goal-based DAMOS quota auto-tuning and monitoring
intervals auto-tuning like self-training mechanisms are such examples.  It
also adds access frequency stability information (age) to the monitoring
results, which makes it enhanced over time.

Sometimes users have to stop DAMON.  In this case, DAMON internal state
that enhanced over the time of the last execution simply goes away.
Restarted DAMON have to train itself and enhance its output from the
scratch.  This makes DAMON less useful in such cases.  Introducing three
such use cases below.

Investigation of DAMON.  It is best to do the investigation online,
especially when it is a production environment.  DAMON therefore provides
features for such online investigations, including DAMOS stats, monitoring
result snapshot exposure, and multiple tracepoints.  When those are
insufficient, and there are additional clues that could be interfered by
DAMON, users have to temporarily stop DAMON to collect the additional
clues.  It is not very useful since many of DAMON internal clues are gone
when DAMON is stopped.  The loss of the monitoring results that improved
over time is also problematic, especially in production environments.

Monitoring of workloads that have different user-known phases.  For
example, in Android, applications are known to have very different access
patterns and behaviors when they are running on the foreground and the
background.  It can therefore be useful to separate monitoring of apps
based on whether they are running on the foreground and on the background.
Having two DAMON threads per application that paused and resumed for the
apps foreground/background switches can be useful for the purpose.  But
such pause/resume of the execution is not supported.

Tests of DAMON.  A few DAMON selftests are using drgn to dump the internal
DAMON status.  The tests show if the dumped status is the same as what the
test code expected.  Because DAMON keeps running and modifying its
internal status, there are chances of data races that can cause false test
results.  Stopping DAMON can avoid the race.  But, since the internal
state of DAMON is dropped, the test coverage will be limited.

Let DAMON execution be paused and resumed without loss of the internal
state, to overhaul the limitations.  For this, introduce a new DAMON
context parameter, namely 'pause'.  API callers can update it while the
context is running, using the online parameters update functions
(damon_commit_ctx() and damon_call()).  Once it is set, kdamond_fn() main
loop will do only limited works excluding the monitoring and DAMOS works,
while sleeping sampling intervals per the work.  The limited works include
handling of the online parameters update.  Hence users can unset the
'pause' parameter again.  Once it is unset, kdamond_fn() main loop will do
all the work again (resumed).  Under the paused state, it also does stop
condition checks and handling of it, so that paused DAMON can also be
stopped if needed.  Expose the feature to the user space via DAMON sysfs
interface.  Also, update existing drgn-based tests to test and use the
feature.

Tests
=====

I confirmed the feature functionality using real time tracing ('perf
trace' or 'trace-cmd stream') of damon:damon_aggregated DAMON tracepoint.
By pausing and resuming the DAMON execution, I was able to see the trace
stops and continued as expected.  Note that the pause feature support is
added to DAMON user-space tool (damo) after v3.1.9.  Users can use
'--pause_ctx' command line option of damo for that, and I actually used it
for my test.  The extended drgn-based selftests are also testing a part of
the functionality.

Patches Sequence
================

Patch 1 introduces the new core API for the pause feature.  Patch 2 extend
DAMON sysfs interface for the new parameter.  Patches 3-5 update design,
usage and ABI documents for the new sysfs file, respectively.  The
following five patches are for tests.  Patch 6 implements a new kunit test
for the pause parameter online commitment.  Patches 7 and 8 extend DAMON
selftest helpers to support the new feature.  Patch 9 extends selftest to
test the commitment of the feature.  Finally, patch 10 updates existing
selftest to be safe from the race condition using the pause/resume
feature.


This patch (of 10):

DAMON supports only start and stop of the execution.  When it is stopped,
its internal data that it self-trained goes away.  It will be useful if
the execution can be paused and resumed with the previous self-trained
data.

Introduce per-context API parameter, 'paused', for the purpose.  The
parameter can be set and unset while DAMON is running and paused, using
the online parameters commit helper functions (damon_commit_ctx() and
damon_call()).  Once 'paused' is set, the kdamond_fn() main loop does only
limited works with sampling interval sleep during the works.  The limited
works include the handling of the online parameters update, so that users
can unset the 'pause' and resume the execution when they want.  It also
keep checking DAMON stop conditions and handling of it, so that DAMON can
be stopped while paused if needed.

Subject: [PATCH 2032/5214] selftests/damon/_damon_sysfs: support pause file
 staging

DAMON test-purpose sysfs interface control Python module, _damon_sysfs, is
not supporting the newly added pause file.  Add the support of the file,
for future test and use of the feature.

Subject: [PATCH 2035/5214] selftests/damon/sysfs.py: pause DAMON before
 dumping status

The sysfs.py test commits DAMON parameters, dump the internal DAMON state,
and show if the parameters are committed as expected using the dumped
state.  While the dumping is ongoing, DAMON is alive.  It can make
internal changes including addition and removal of regions.  It can
therefore make a race that can result in false test results.  Pause DAMON
execution during the state dumping to avoid such races.

Subject: [PATCH 2037/5214] mm/memcontrol: hoist pstatc_pcpu assignment out of
 CPU loop

In mem_cgroup_alloc(), the assignment of pstatc_pcpu is invariant with
respect to the for_each_possible_cpu() loop: both the 'parent' pointer and
'parent->vmstats_percpu' remain constant throughout all iterations.

The original code redundantly re-evaluated the 'if (parent)' condition and
reassigned pstatc_pcpu on every CPU iteration, then repeated the same
ternary check 'parent ?  pstatc_pcpu : NULL' when storing into
statc->parent_pcpu.

Move the single conditional assignment of pstatc_pcpu to before the loop,
resolving both the loop-invariant placement issue and the duplicated null
check.  On systems with a large number of possible CPUs, this eliminates
repeated branch evaluation with no functional change.

No functional change intended.

Subject: [PATCH 2038/5214] vmalloc: add __GFP_SKIP_KASAN support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Patch series "kasan: hw_tags: Disable tagging for stack and page-tables",
v4.

Stacks and page tables are always accessed with the match-all tag, so
assigning a new random tag every time at allocation and setting invalid
tag at deallocation time, just adds overhead without improving the
detection.

With __GFP_SKIP_KASAN the page keeps its poison tag and KASAN_TAG_KERNEL
(match-all tag) is stored in the page flags while keeping the poison tag
in the hardware.  The benefit of it is that 256 tag setting instruction
per 4 kB page aren't needed at allocation and deallocation time.

Thus match-all pointers still work, while non-match tags (other than
poison tag) still fault.

__GFP_SKIP_KASAN only skips for KASAN_HW_TAGS mode, so coverage is
unchanged.

Benchmark:
The benchmark has two modes. In thread mode, the child process forks
and creates N threads. In pgtable mode, the parent maps and faults a
specified memory size and then forks repeatedly with children exiting
immediately.

Thread benchmark:
2000 iterations, 2000 threads:	2.575 s → 2.229 s (~13.4% faster)

The pgtable samples:
- 2048 MB, 2000 iters		19.08 s → 17.62 s (~7.6% faster)


This patch (of 3):

For allocations that will be accessed only with match-all pointers (e.g.,
kernel stacks), setting tags is wasted work.  If the caller already set
__GFP_SKIP_KASAN, skip tag setting of vmalloc pages.

Before this patch, __GFP_SKIP_KASAN wasn't being used with vmalloc APIs.
So it wasn't being checked.  Now its being checked and acted upon.  Other
KASAN modes are unchanged because __GFP_SKIP_KASAN is ignored for them in
the page allocator, and in vmalloc too we ignore this flag for them.

This is a preparatory patch for optimizing kernel stack allocations.

Subject: [PATCH 2039/5214] kasan: skip HW tagging for all kernel thread stacks

HW-tag KASAN never checks kernel stacks because stack pointers carry the
match-all tag, so setting/poisoning tags is pure overhead.

- Add __GFP_SKIP_KASAN to THREADINFO_GFP so every stack allocator that
  uses it skips tagging (fork path plus arch users)
- Add __GFP_SKIP_KASAN to GFP_VMAP_STACK for the fork-specific vmap
  stacks.
- When reusing cached vmap stacks, skip kasan_unpoison_range() if HW tags
  are enabled.

Software KASAN is unchanged; this only affects tag-based KASAN.

Subject: [PATCH 2040/5214] mm: skip KASAN tagging for page-allocated page
 tables

Page tables are always accessed via the linear mapping with a match-all
tag, so HW-tag KASAN never checks them.  For page-allocated tables (PTEs
and PGDs etc), avoid the tag setup and poisoning overhead by using
__GFP_SKIP_KASAN.  SLUB-backed page tables are unchanged for now.  (They
aren't widely used and require more SLUB related skip logic.  Leave it
later.)

Subject: [PATCH 2041/5214] mm/damon: introduce
 damon_set_region_system_rams_default()

Patch series "mm/damon/reclaim,lru_sort: monitor all system rams by
default".

DAMON_RECLAIM and DAMON_LRU_SORT set the biggest 'System RAM' resource of
the system as the default monitoring target address range.  The main
intention behind the design is to minimize the overhead coming from
monitoring of non-System RAM areas.

This could result in an odd setup when there are multiple discrete System
RAMs of considerable sizes.  For example, there are System RAMs each
having 500 GiB size.  In this case, only the first 500 GiB will be set as
the monitoring region by default.  This is particularly common on NUMA
systems.  Hence the modules allow users to set the monitoring target
address range using the module parameters if the default setup doesn't
work for them.  In other words, the current design trades ease of setup
for lower overhead.

However, because DAMON utilizes the sampling based access check and the
adaptive regions adjustment mechanisms, the overhead from the monitoring
of non-System RAM areas should be negligible in most setups.  Meanwhile,
the setup complexity is causing real headaches for users who need to run
those modules on various types of systems.  That is, the current tradeoff
is not a good deal.

Set the physical address range that can cover all System RAM areas of the
system as the default monitoring regions for DAMON_RECLAIM and
DAMON_LRU_SORT.

Technically speaking, this is changing documented behavior.  However, it
makes no sense to believe there is a real use case that really depends on
the old weird default behavior.  If the old default behavior was working
for them in the reasonable way, this change will only add a negligible
amount of monitoring overhead.  If it didn't work, the users may already
be using manual monitoring regions setup, and they will not be affected by
this change.

Patches Sequence
================

Patch 1 introduces a new core function that will be used for the new
default monitoring target region setup.  Patch 2 and 3 update
DAMON_RECLAIM and DAMON_LRU_SORT to use the new function instead of the
old one, respectively.  Patch 4 removes the old core function that was
replaced by the new one, as there is no more user of it.  Patch 5 updates
DAMON_STAT to use the new one instead of its in-house nearly-duplicate
self implementation of the functionality.  Finally patches 6 and 7 update
the DAMON_RECLAIM and DAMON_LRU_SORT user documentation for the new
behaviors, respectively.


This patch (of 7):

damon_set_region_biggest_system_ram_default() sets the monitoring target
region as the caller requested.  If the caller didn't specify the region,
it finds the biggest System RAM of the system and sets it as the target
region.  When there are more than one considerable size of System RAM
resources in the system, the default target setup makes no sense.
Introduce a variant, namely damon_set_region_system_rams_default().  It
sets a physical address range that covers all System RAM resources as the
default target region.

Subject: [PATCH 2042/5214] mm/damon/reclaim: cover all system rams

DAMON_RECLAIM allows users to set the physical address range to monitor
and do the work on.  When users don't explicitly set the range, the
biggest System RAM resource of the system is selected as the monitoring
target address range.  The intention was to reduce the overhead from
monitoring non-System RAM areas because monitoring of non-System RAM may
be meaningless.  However, because of the sampling based access check and
adaptive regions adjustment, the overhead should be negligible.  It makes

Subject: [PATCH 2043/5214] mm/damon/lru_sort: cover all system rams

DAMON_LRU_SORT allows users to set the physical address range to monitor
and do the work on.  When users don't explicitly set the range, the
biggest system ram resource of the system is selected as the monitoring
target address range.  The intention was to reduce the overhead from
monitoring non-System RAM areas because monitoring non-System RAM may be
meaningless.  However, because of the sampling based access check and
adaptive regions adjustment, the overhead should be negligible.  It makes
more sense to just cover all system rams of the system.  Do so.

Subject: [PATCH 2048/5214] selftests/mm: khugepaged: initialize file contents
 via mmap

file_setup_area() currently allocates anonymous memory, fills it, and
writes it into the backing file used for collapse testing.

Instead of copying data through write(), resize the file with ftruncate(),
map it directly with MAP_SHARED, and initialize the mapped area in place.

This simplifies the setup path and avoids the need for explicit partial
write handling.

Subject: [PATCH 2049/5214] mm/khugepaged: return -EAGAIN for
 SCAN_PAGE_HAS_PRIVATE in MADV_COLLAPSE

MADV_COLLAPSE uses errno values to provide actionable feedback to
userspace.  Temporary resource constraints are mapped to -EAGAIN so the
caller may retry, while intrinsic failures of the specified range are
mapped to -EINVAL.

collapse_file() returns SCAN_PAGE_HAS_PRIVATE when filemap_release_folio()
fails while isolating file-backed folios for collapse.  This currently
falls through the default case in madvise_collapse_errno() and is reported
to userspace as -EINVAL.

However, filemap_release_folio() failure commonly reflects temporary folio
state rather than a permanently uncollapsible range.

For example, ext4 returns false when a folio still has dirty journalled
data, btrfs returns false for dirty or writeback folios before extent
state release, and NFS may return false while reclaiming
filesystem-private folio state.

In such cases, retrying MADV_COLLAPSE after writeback, reclaim or journal
progress may succeed.  This matches the existing -EAGAIN handling for
SCAN_PAGE_DIRTY_OR_WRITEBACK and other transient collapse failures more
closely than -EINVAL.

Therefore, map SCAN_PAGE_HAS_PRIVATE to -EAGAIN so userspace receives
retryable feedback for this temporary failure path.

Subject: [PATCH 2050/5214] Docs/admin-guide/mm/damon/usage: mark scheme
 filters sysfs dir as deprecated

Patch series "mm/damon/sysfs: document filters/ directory as deprecated".

Commit ab71d2d30121 ("mm/damon/sysfs-schemes: let
damon_sysfs_scheme_set_filters() be used for different named directories")
introduced alternatives of 'filters' directory, namely core_filters/ and
'ops_filters/ directories.  Now the alternatives are well stabilized and
ready for all users.  All filters/ directory use cases are expected to be
able to be migrated to the alternatives.  An LTS kernel having the
alternatives, namely 6.18.y, is also released.  Existence of filters/
directory is only confusing.

It would be better not immediately removing the directory, though.  There
could be users that need time before migrating to the alternatives.  There
might be unexpected use cases that the alternatives cannot support.  Doing
the deprecation step by step across multiple years like DAMON debugfs
deprecation would be safer.  Start the deprecation changes by announcing
the deprecation on the documents.

Every year, one more action for completely removing the directory will be
followed, like DAMON debugfs deprecation did.  Following yearly actions
are currently expected.  In 2027, deprecation warning kernel messages will
be printed once, for use of filters/ directory.  In 2028, filters/
directory will be renamed to filters_DEPRECATED/.  In 2029,
filters_DEPRECATED/ directory will be removed.


This patch (of 2):

The alternatives of 'filters/' directory, namely 'core_filters/' and
'ops_filters/', can fully support all the features 'filters/' directory
can do, and provide better user experience.  Having 'filters/' directory
is only confusing to users.  Announce it as deprecated on the usage
document.

on 'core_filter/' directory, to make the old descriptions ready to be

Subject: [PATCH 2052/5214] mm: use zone lock guard in
 reserve_highatomic_pageblock()

Patch series "mm: use spinlock guards for zone lock", v3.

This series uses spinlock guard for zone lock across several mm functions
to replace explicit lock/unlock patterns with automatic scope-based
cleanup.

This simplifies the control flow by removing 'flags' variables, goto
labels, and redundant unlock calls.

Patches are ordered by decreasing value.  The first six patches simplify
the control flow by removing gotos, multiple unlock paths, or 'ret'
variables.  The last two are simpler lock/unlock pair conversions that
only remove 'flags' and can be dropped if considered unnecessary churn.

Binary size increase is +39 bytes, with Peter Zijlstra's fix for guards
[1] applied.  This is due to the compiler not being able to deduplicate
epilogue and eliminate redundant NULL check.  See discussion [2] for more
details.  I proposed a patch [3] that fixes this, but until it is merged
we need to assume +39 bytes will stay (though it is compiler dependent).


This patch (of 8):

Use the spinlock_irqsave zone lock guard in reserve_highatomic_pageblock()
to replace the explicit lock/unlock and goto out_unlock pattern with
automatic scope-based cleanup.

Subject: [PATCH 2055/5214] mm: use zone lock guard in
 set_migratetype_isolate()

Use spinlock_irqsave scoped lock guard in set_migratetype_isolate() to
replace the explicit lock/unlock pattern with automatic scope-based
cleanup.  The scoped variant is used to keep dump_page() outside the
locked section to avoid a lockdep splat.

Use spinlock_irqsave zone lock guard in take_page_off_buddy() to replace
the explicit lock/unlock pattern with automatic scope-based cleanup.

This also allows to return directly from the loop, removing the 'ret'

Subject: [PATCH 2060/5214] mm/filemap: count only the faulting address as a
 mmap hit

Patch series "mm/filemap: tighten mmap_miss hit accounting", v3.

mmap_miss is increased when synchronous mmap readahead is needed, and
decreased when filemap_map_pages() maps folios that are already in the
page cache.  The decrease side can over-credit hits in two cases:

  - fault-around installs nearby PTEs even though the fault only proves
    that the faulting address was accessed;
  - after synchronous mmap readahead returns VM_FAULT_RETRY, the retry
    can find the folio brought in by the same miss and immediately
    cancel that miss.

Current evidence comes from a local KVM/data-disk microbenchmark using
mmap_miss_probe, with an 8 GiB guest, 2 vCPUs, 8192 KiB read_ahead_kb,
cold page cache before each run, 1% of the file accessed, and medians of 3
runs.

mmap_miss_probe mmap()s a prepared file with MADV_NORMAL and then touches
one byte at selected base-page offsets.  The access order is random,
sequential, or a fixed page stride.  The harness drops caches before each
run and samples /proc/vmstat around that access loop.

The 20 GiB case below is a larger-than-memory file case in an 8 GiB guest.
No separate memory hog was used.  The 4 GiB case uses the same 8 GiB
guest but keeps the file fit-in-memory.

Each case used a fresh temporary qcow2 data disk, seen by the guest as
/dev/vda, formatted as ext4 and mounted at /mnt/mmap-matrix.

Each result is "pgpgin GiB / elapsed seconds".  "pgpgin GiB" is the delta
of the guest /proc/vmstat pgpgin counter, converted from KiB to GiB; it is
used here as an approximate block input counter, not as resident memory or
exact application IO.  "Elapsed seconds" is the wall-clock runtime of the
whole mmap_miss_probe access pass, not per-access latency.

For the 20 GiB larger-than-memory case:

        workload       before                after
        random         223.377 GiB/101.293s  1.010 GiB/4.790s
        stride1021     204.214 GiB/97.557s   204.208 GiB/108.086s
        stride2053     409.584 GiB/193.700s  0.970 GiB/3.685s
        stride4099     406.452 GiB/134.241s  0.975 GiB/3.499s
        sequential       0.212 GiB/0.050s    0.212 GiB/0.057s

For the 4 GiB fit-in-memory case:

        workload       before              after
        random         3.987 GiB/1.960s    0.980 GiB/1.221s
        stride1021     4.002 GiB/1.838s    4.002 GiB/1.851s
        stride2053     3.991 GiB/1.835s    0.811 GiB/0.985s
        stride4099     4.001 GiB/1.836s    0.819 GiB/1.037s
        sequential     0.056 GiB/0.013s    0.056 GiB/0.018s

The 20 GiB setup also has an ablation.  P1 is only the faulting-address
hit accounting change.  P2-only is only the FAULT_FLAG_TRIED retry
filter.  P1+P2 is the combined accounting change:

        workload    variant   result
        random      baseline  223.377 GiB/101.293s
        random      P1        223.268 GiB/98.481s
        random      P2-only   223.257 GiB/100.091s
        random      P1+P2     1.010 GiB/4.790s
        stride2053  baseline  409.584 GiB/193.700s
        stride2053  P1        409.584 GiB/197.645s
        stride2053  P2-only   15.722 GiB/5.485s
        stride2053  P1+P2     0.970 GiB/3.685s
        sequential  baseline  0.212 GiB/0.050s
        sequential  P1        0.212 GiB/0.046s
        sequential  P2-only   0.212 GiB/0.050s
        sequential  P1+P2     0.212 GiB/0.057s

After the v2 implementation refactor, only the final P1+P2 shape was rerun
in the same setup.  The numbers stayed in line with the v1 P1+P2 rows
above:

        workload       larger-than-memory case    fit-in-memory case
                       20 GiB file, 1% access    4 GiB file, 1% access
        random           1.010 GiB/4.383s          0.980 GiB/1.088s
        stride1021     204.216 GiB/105.601s        4.001 GiB/1.783s
        stride2053       0.970 GiB/3.760s          0.810 GiB/0.908s
        stride4099       0.975 GiB/3.410s          0.818 GiB/0.870s
        sequential       0.212 GiB/0.060s          0.056 GiB/0.016s

This does not claim to solve every sparse pattern.  The stride1021 rows
are intentionally shown as a boundary: with 8192 KiB read_ahead_kb,
file->f_ra.ra_pages is 2048 base pages, and synchronous mmap read-around
uses a 2048-page window centered around the fault, roughly [index - 1024,
index + 1023].  stride1021 is 1021 * 4 KiB = 4084 KiB, so the next access
lands inside the previous read-around window.  About every other access
can be a real faulting-address page-cache hit, and the other half can each
read about 8 MiB.  For about 52k accesses in the 20 GiB/1% run, half of
them times 8 MiB is about 205 GiB, matching the observed 204 GiB.


This patch (of 2):

filemap_map_pages() reduces file->f_ra.mmap_miss when fault-around maps
folios that are already present in the page cache.  That hit accounting is
too generous because fault-around can install PTEs around the faulting
address even though the fault only proves that the faulting address was
accessed.

Move the mmap_miss update back into filemap_map_pages(), drop the
mmap_miss argument from the helper functions, and decrement mmap_miss only
when the helper return value shows that the faulting address was mapped.
Keep the existing workingset-folio behavior unchanged.

Subject: [PATCH 2061/5214] mm/filemap: do not count FAULT_FLAG_TRIED retries
 as mmap hits

A fault that starts synchronous mmap readahead can return VM_FAULT_RETRY
after dropping mmap_lock.  The retry may then map the folio brought in by
that same miss.

Do not let this retry decrement mmap_miss.  The retry still maps the folio
from the page cache; it just does not count as a useful mmap readahead
hit.

Subject: [PATCH 2062/5214] selftests/cgroup: fix hardcoded page size in
 test_percpu_basic

Patch series "selftests/cgroup: Fix false positive failures in
test_percpu_basic", v2.

This patch series addresses two separate issues that cause false
positive failures in the test_percpu_basic test within the cgroup
kmem selftests.

The first issue stems from a hardcoded assumption about the system
page size, which breaks the test on architectures with larger page
sizes.

The second issue is an overly strict memory check that fails to
account for the slab metadata allocated during cgroup creation.


This patch (of 2):

MAX_VMSTAT_ERROR uses a hardcoded page size of 4096, which assumes 4K
pages.  This causes test_percpu_basic to fail on systems where the kernel
is configured with a larger page size, such as aarch64 systems using 16K
or 64K pages, where the maximum permissible discrepancy between
memory.current and percpu charges is proportionally larger.

Replace the hardcoded 4096 with sysconf(_SC_PAGESIZE) to correctly derive
the page size at runtime regardless of the underlying architecture or
kernel configuration.

Subject: [PATCH 2063/5214] selftests/cgroup: include slab in test_percpu_basic
 memory check

test_percpu_basic() currently compares memory.current against only
memory.stat:percpu after creating 1000 child cgroups.

Observed failure:
  #./test_kmem
  ok 1 test_kmem_basic
  ok 2 test_kmem_memcg_deletion
  ok 3 test_kmem_proc_kpagecgroup
  ok 4 test_kmem_kernel_stacks
  ok 5 test_kmem_dead_cgroups
  memory.current 11530240
  percpu 8440000
  not ok 6 test_percpu_basic

That assumption is too strict: child cgroup creation also allocates
slab-backed metadata, so memory.current is expected to be larger than
percpu alone. One visible path is:

  cgroup_mkdir()
    cgroup_create()
      cgroup_addrm_file()
        cgroup_add_file()
          __kernfs_create_file()
            __kernfs_new_node()
              kmem_cache_zalloc()

These kernfs allocations are charged as slab and show up in
memory.stat:slab.

Update the check to compare memory.current against (percpu + slab)
within MAX_VMSTAT_ERROR, and print slab/delta in the failure message to
improve diagnostics.

Subject: [PATCH 2064/5214] mm/damon/reclaim: add autotune_monitoring_intervals
 parameter

Patch series "mm/damon/reclaim: support monitoring intervals auto-tuning".

The monitoring intervals auto-tuning feature of DAMON has proven to be
useful in multiple environments.  Add a new DAMON_RECLAIM parameter for
supporting the feature, and update the document for the new parameter.


This patch (of 2):

DAMON's monitoring intervals auto-tuning feature has proven to be useful
in multiple environments.  DAMON_RECLAIM is still asking users to do the
manual tuning of the intervals.  Add a module parameter for utilizing the
auto-tuning feature with the suggested default setup.

Note that use of the auto-tuning overrides the manually entered monitoring
intervals.  Also, note that the 'min_age' will dynamically changed
proportional to auto-tuned intervals.  It is recommended to use 'min_age'
short enough and use 'quota_mem_pressure_us' like coldness threshold
auto-tuning features together.

Subject: [PATCH 2066/5214] mm/damon/stat: add a parameter for reading kdamond
 pid

Patch series "mm/damon/stat: add kdamond_pid parameter".

DAMON_STAT doesn't provide the pid of its kdamond, unlike DAMON_RECLAIM
and DAMON_LRU_SORT.  This makes user-space management of DAMON_STAT
unnecessarily complicated.  Provide the information via a new parameter,
namely kdamond_pid, and document it.


This patch (of 2):

Knowing the pid of the kdamonds can help user-space management including
monitoring of DAMON's system resource consumption.  To make it easier,
DAMON_SYSFS, DAMON_RECLAIM and DAMON_LRU_SORT provide the pid information.
DAMON_STAT is not providing it, though.  Expose the pid of DAMON_STAT
kdamond via a new read-only module parameter, namely kdamond_pid.  This
also makes DAMON modules usage more standardized, because DAMON_RECLAIM
and DAMON_LRU_SORT also provide the information via their read-only
parameters of the same name.

Subject: [PATCH 2069/5214] mm/swap: add cond_resched() in
 swap_reclaim_full_clusters to prevent softlockup

We hit a real softlockup in an internal stress test environment.  The
workload was LTP memory/swap stress on a large arm64 machine, with 320
CPUs, about 1TB memory and an 8.6GB swap device.  The system was under
heavy load and the swap device had a large number of full clusters.  The
softlockup was triggered during a stress test after about 3 days.

So, add periodic cond_resched() calls during large full_clusters
reclaim operations to prevent softlockup issues.

Detailed call trace as follow:

Subject: [PATCH 2070/5214] mm/kmemleak: dedupe verbose scan output by
 allocation backtrace

Patch series "mm/kmemleak: dedupe verbose scan output", v3.

I am starting to run with kmemleak in verbose enabled in some "probe
points" across the my employers fleet so that suspected leaks land in
dmesg without needing a separate read of /sys/kernel/debug/kmemleak.

The downside is that workloads which leak many objects from a single
allocation site flood the console with byte-for-byte identical backtraces.
Hundreds of duplicates per scan are common, drowning out distinct leaks
and unrelated kernel messages, while adding no signal beyond the first
occurrence.

This series collapses those duplicates inside kmemleak itself.  Each
unique stackdepot trace_handle prints once per scan, followed by a short
summary line when more than one object shares it:

  kmemleak: unreferenced object 0xff110001083beb00 (size 192):
  kmemleak:   comm "modprobe", pid 974, jiffies 4294754196
  kmemleak:   ...
  kmemleak:   backtrace (crc 6f361828):
  kmemleak:     __kmalloc_cache_noprof+0x1af/0x650
  kmemleak:     ...
  kmemleak:   ... and 71 more object(s) with the same backtrace

The "N new suspected memory leaks" tally and the contents of
/sys/kernel/debug/kmemleak are unchanged - the per-object detail is still
available on demand, only the verbose (dmesg) output is collapsed.

Patch 1 is the kmemleak change.

Patch 2 adds a selftest that loads samples/kmemleak's CONFIG_SAMPLE
kmemleak-test module to generate ten leaks sharing one call site and
checks that the printed count is strictly less than the reported leak
total.  Not sure if Patch 2 is useful or not, if not, it is easier to
discard.


This patch (of 2):

In kmemleak's verbose mode, every unreferenced object found during a scan
is logged with its full header, hex dump and 16-frame backtrace.
Workloads that leak many objects from a single allocation site flood dmesg
with byte-for-byte identical backtraces, drowning out distinct leaks and
other kernel messages.

Dedupe within each scan using stackdepot's trace_handle as the key: for
every leaked object with a recorded stack trace, look up the
representative kmemleak_object in a per-scan xarray keyed by trace_handle.
The first sighting stores the object pointer (with a get_object()
reference) and sets object->dup_count to 1; later sightings just bump
dup_count on the representative.  After the scan, walk the xarray once and
emit each unique backtrace, followed by a single summary line when more
than one object shares it.

Leaks whose trace_handle is 0 (early-boot allocations tracked before
kmemleak_init() set up object_cache, or stack_depot_save() failures under
memory pressure) cannot be deduped, so they are still printed inline via
the same locked OBJECT_ALLOCATED-checked helper.  The contents of
/sys/kernel/debug/kmemleak are unchanged - only the verbose console output
is collapsed.

Safety notes:

 - The xarray store happens outside object->lock: object->lock is a
   raw spinlock, while xa_store() may grab xa_node slab locks at a
   higher wait-context level which lockdep flags as invalid.
   trace_handle is captured under object->lock (which serialises with
   kmemleak_update_trace()'s writer), so it is safe to use after
   dropping the lock.

 - get_object() pins the kmemleak_object metadata across
   rcu_read_unlock(), but the underlying tracked allocation can still
   be freed concurrently. The deferred print path therefore re-acquires
   object->lock and re-checks OBJECT_ALLOCATED via print_leak_locked()
   before touching object->pointer; __delete_object() clears that flag
   under the same lock before the user memory goes away. The same
   helper is used by the trace_handle == 0 and xa_store() failure
   fallbacks, so every printer in the new path has identical safety
   guarantees.

 - If get_object() fails after we set OBJECT_REPORTED, the object is
   already being torn down (use_count hit zero); the leak count is
   still accurate but the verbose line is dropped, which is correct
   - the memory was freed concurrently and is no longer a leak.

 - If xa_store() fails to allocate an xa_node under memory pressure,
   we fall back to printing inline via print_leak_locked() instead of
   silently dropping the leak.

 - The hex dump is skipped for coalesced entries (dup_count > 1):
   bytes would differ across objects sharing a backtrace anyway, and
   skipping it removes the only remaining read of object->pointer's
   contents in the deferred path. The representative's reported size
   may also differ from the coalesced objects' sizes; the printed
   trace_handle reflects the representative's current value rather
   than the value used as the dedup key, which is normally - but not
   strictly - identical.

Subject: [PATCH 2071/5214] selftests/mm: add kmemleak verbose dedup test

Add a regression test for the per-scan verbose dedup added in the
preceding commit.  The test loads samples/kmemleak's helper module
(CONFIG_SAMPLE_KMEMLEAK=m) to generate orphan allocations, several of
which share an allocation backtrace, runs four kmemleak scans with verbose
printing enabled, then walks dmesg looking for two "unreferenced object"
reports within a single scan that share an identical backtrace - which
would mean dedup failed to collapse them.

The test is intentionally permissive on detection but strict on
regressions:

 - PASS when no duplicates are observed, regardless of whether the
   dedup summary line ("... and N more object(s) with the same
   backtrace") was actually emitted. Per-CPU chunk reuse, slab
   freelist pointers, kernel stack residue and CONFIG_DEBUG_KMEMLEAK_
   AUTO_SCAN can all keep most of the orphans "still referenced" or
   reported across many separate scans, so the dedup path may have
   nothing to fold within one scan. That is not a regression.

 - PASS reports whether dedup actually fired, so a passing run on a
   well-behaved environment is still informative.

 - FAIL when two same-backtrace reports land in a single scan (clear
   dedup regression).

 - FAIL when kmemleak's own per-scan tally counts leaks but the
   verbose path emits zero "unreferenced object" lines - that catches
   a regression in the verbose printer itself, which would otherwise
   pass the duplicate check trivially.

 - SKIP when kmemleak is absent, disabled at runtime, or the helper
   module is not built.

The dmesg parser anchors stack-frame matching to the indentation kmemleak
uses for them (4+ spaces under "kmemleak: ") so unrelated kmemleak
warnings landing between reports do not get lumped into the backtrace key
and mask a duplicate.

+# Regression test for kmemleak's per-scan verbose dedup.
+#
+# Loads samples/kmemleak's helper module to generate orphan allocations
+# (some of which share an allocation backtrace), runs a few kmemleak
+# scans with verbose printing enabled, and verifies that no two
+# "unreferenced object" reports within a single scan share the same
+# backtrace - which would mean dedup failed to collapse them.
+#
+# This test is intentionally permissive: the kmemleak-test module's
+# leaks frequently get reported across many separate scans (per-CPU
+# chunk reuse, slab freelist pointers, kernel stack residue), so dedup
+# may never have anything to fold within one scan. That is not a
+# regression. The test only fails when it actually catches dedup not
+# happening on input that should have triggered it - i.e. two reports
+# with identical backtraces in the same scan.

Subject: [PATCH 2072/5214] proc: add tgid_iter.pid_ns member

next_tgid() accepts pid namespace as an argument, but it never changes
during readdir (which would be unthinkable thing to do anyway).

Move it inside iterator type and hide from direct usage.

Subject: [PATCH 2073/5214] proc: rewrite next_tgid()

* deduplicate "iter.tgid += 1" line,
  Right now it is done once inside next_tgid() itself and second time
  inside "for" loop.

* deduplicate next_tgid() call itself with different loop style:

	auto it = make_tgid_iter();
	while (next_tgid(&it)) {
		...
	}

  gcc seems to inline it twice:

  	$ ./scripts/bloat-o-meter ../vmlinux-000 ../obj/vmlinux
	add/remove: 0/1 grow/shrink: 1/0 up/down: 100/-245 (-145)
	Function                                     old     new   delta
	proc_pid_readdir                             531     631    +100
	next_tgid                                    245       -    -245

* make tgid_iter.pid_ns const
  it never changes during readdir anyway

Subject: [PATCH 2074/5214] checkpatch: allow passing config directory

checkpatch.pl searches for .checkpatch.conf in $CWD, $HOME and
$CWD/.scripts.  Allow passing a single directory via CHECKPATCH_CONFIG_DIR
environment variable (empty value is ignored).  This allows to directly
use project configuration file for projects which vendored checkpatch.pl
(e.g.  LTP or u-boot).

Although it'd be more convenient for user to have --conf-dir option
(instead of using environment variable), code would get ugly because
options from the configuration file needs to be read before processing
command line options with Getopt::Long.

While at it, document directories and environment variable in -h help
and HTML doc.

This avoids forcing this for projects which vendored checkpatch.pl (e.g.

 __proc_create

Replace strlen(fn) with strnlen(fn, NAME_MAX + 1) when validating the
final path component in __proc_create().

This preserves the existing name limit while bounding the length scan to
one byte past the maximum name length.  Handle empty names separately, and
treat names longer than NAME_MAX as too long.

Subject: [PATCH 2077/5214] tools/accounting/getdelays: fix -Wformat-truncation
 warning in format_timespec

Reproduce with GCC 13.3.0:

  $ cd tools/accounting
  $ make

This emits:

getdelays.c: In function `format_timespec':
getdelays.c:218:67: warning: `:' directive output may be truncated writing 1 byte into a region of size between 0 and 16 [-Wformat-truncation=]
  218 |         snprintf(buffer, sizeof(buffer), "%04d-%02d-%02dT%02d:%02d:%02d",
      |
getdelays.c:218:9: note: `snprintf' output between 20 and 72 bytes into a destination of size 32

The problem is that %04d and %02d specify minimum field widths only. GCC
cannot prove that formatting tm_year + 1900 and the other struct tm
fields will always fit in the fixed 32-byte buffer, so it warns about
possible truncation.

Fix this by replacing the manual snprintf() formatting with
strftime("%Y-%m-%dT%H:%M:%S", ...). That matches the data we already have
in struct tm, keeps the intended timestamp format, and avoids the warning
when building tools/accounting with GCC.

Subject: [PATCH 2078/5214] ocfs2: use kzalloc for quota recovery bitmap
 allocation

ocfs2 quota recovery allocates a bitmap buffer with kmalloc and does not
fully initialize it.  This can lead to use of uninitialized bits during
quota recovery from a corrupted filesystem image.

Use kzalloc instead to ensure the bitmap is zero-initialized.

Subject: [PATCH 2082/5214] taskstats: retain dead thread stats in TGID queries

Patch series "taskstats: fix TGID dead-thread stat retention", v3.

This series fixes a taskstats TGID aggregation bug where fields added in
the TGID query path were not preserved after thread exit, and adds a
kselftest covering the regression.

The first patch keeps the cached TGID aggregate used for dead threads in
step with the fields already accumulated for live threads, and also fixes
the final TGID exit notification emitted when group_dead is true.

The second patch adds a kselftest that verifies TGID CPU stats do not
regress after a worker thread exits and has been reaped.


This patch (of 2):

fill_stats_for_tgid() builds TGID stats from two sources: the cached
aggregate in signal->stats and a scan of the live threads in the group.

However, fill_tgid_exit() only accumulates delay accounting into
signal->stats.  This means that once a thread exits, TGID queries lose the
fields that fill_stats_for_tgid() adds for live threads.

This gap was introduced incrementally by two earlier changes that extended
fill_stats_for_tgid() but did not make the corresponding update to
fill_tgid_exit():

- commit 8c733420bdd5 ("taskstats: add e/u/stime for TGID command")
  added ac_etime, ac_utime, and ac_stime to the TGID query path.
- commit b663a79c1915 ("taskstats: add context-switch counters")
  added nvcsw and nivcsw to the TGID query path.

As a result, those fields were accounted for live threads in TGID queries,
but were dropped from the cached TGID aggregate after thread exit.  The
final TGID exit notification emitted when group_dead is true also copies
that cached aggregate, so it loses the same fields.

Factor the per-task TGID accumulation into tgid_stats_add_task() and use
it in both fill_stats_for_tgid() and fill_tgid_exit().  This keeps the
cached aggregate used for dead threads aligned with the live-thread
accumulation used by TGID queries.

Subject: [PATCH 2083/5214] selftests/acct: add taskstats TGID retention test

Add a kselftest for the taskstats TGID aggregation fix.

The test creates a worker thread, snapshots TGID taskstats while the
worker is still alive, lets the worker exit, and then verifies that the
TGID CPU total does not regress after the thread has been reaped.

The pass/fail check intentionally keys off ac_utime + ac_stime only, which
is the primary user-visible regression fixed by the taskstats change and
is less sensitive to scheduling noise than context-switch counters.

Subject: [PATCH 2084/5214] seq_buf: export seq_buf_putmem_hex() and add KUnit
 tests

The seq_buf KUnit suite does not exercise seq_buf_putmem_hex().

Add one test for the len > 8 chunking path and one overflow test where a
later chunk no longer fits in the buffer.

Export seq_buf_putmem_hex() as well so SEQ_BUF_KUNIT_TEST=m links cleanly.
Without the export, modpost reports seq_buf_putmem_hex as undefined when
seq_buf_kunit is built as a module.

Subject: [PATCH 2085/5214] get_maintainer: add --json output mode

Add a --json flag to get_maintainer.pl that emits structured JSON output,
making results machine-parseable for CI systems, IDE integrations, and
AI-assisted development tools.

The JSON output includes a maintainers array with structured name, email,
and role fields, plus optional arrays for scm, status, subsystem, web, and
bug information when those flags are enabled.

Normal text output behavior is completely unchanged when --json is not
specified.

Subject: [PATCH 2086/5214] treewide: fix indentation and whitespace in Kconfig
 files

Clean up inconsistent indentation (mixing tabs and spaces) and remove
extraneous whitespace in several Kconfig files across the tree.  This is a
purely cosmetic change to improve readability.

Adjust indentation from spaces to tab (+optional two spaces) as in
coding style with command like:

$ sed -e 's/^        /\t/' -i */Kconfig

 escape cases

Patch series "lib/tests: string_helpers: Slight improvements".

Two ad-hoc patches to improve the test module.  It was induced by another
patch that poorly tried to add (existing) test cases and make me revisit
string_helpers_kunit.c.


This patch (of 2):

Currently the escape and unescape test cases go in one step.  Decouple
them for the better granularity and understanding test coverage in the
results.

Subject: [PATCH 2089/5214] init.h: discard exitcall symbols early

Any __exitcall() and built-in module_exit() handler is marked as __used,
which leads to the code being included in the object file and later
discarded at link time.

As far as I can tell, this was originally added at the same time as
initcalls were marked the same way, to prevent them from getting dropped
with gcc-3.4, but it was never actaully necessary to keep exit functions
around.

Mark them as __maybe_unused instead, which lets the compiler treat the
exitcalls as entirely unused, and make better decisions about dropping
specializing static functions called from these.

Subject: [PATCH 2090/5214] lib/base64: validate before writing in decode tail
 path

Patch series "lib/base64: decode fixes", v2.

Two small fixes for lib/base64.c:

1. base64_decode() writes a decoded byte to the output buffer before
   validating the input in the trailing-bytes path. Move the validity
   checks before any writes so dst is untouched on invalid input.

2. The @padding kernel-doc for base64_decode() was copy-pasted from
   base64_encode() and describes the wrong direction.


This patch (of 2):

The trailing-bytes path in base64_decode() writes a decoded byte to the
output buffer before checking whether the input characters are valid.  If
the input is malformed, garbage is written to dst before the function
returns -1.

Move the validity checks before any writes so the output buffer is left
untouched on invalid input.

 base64_decode()

The @padding kernel-doc for base64_decode() says "whether to append '='
padding characters", which was copy-pasted from base64_encode().  In the
decode context, it controls whether the input is expected to include
padding, not whether to append it.

Subject: [PATCH 2092/5214] kselftest/filelock: use ksft_perror()

Patch series "selftests/filelock: Make output more kselftestish", v4.

This series makes the output from the ofdlocks test a bit easier for
tooling to work with, and also ignores the generated file while we're
here.


This patch (of 3):

The ofdlocks test reports some errors via perror() which does not produce
KTAP output, convert to ksft_perror() which does.

Subject: [PATCH 2093/5214] kselftest/filelock: report each test in oftlocks
 separately

The filelock test checks four different things but only reports an overall
status, convert to use ksft_test_result() for these individual tests.
Each test depends on the previous ones so we still bail out if any of them
fail but we get a bit more information from UIs parsing the results.

Subject: [PATCH 2095/5214] rust: uaccess: use INLINE_COPY_TO_USER to guard
 copy_to_user()

Patch series "uaccess: unify inline vs outline copy_{from,to}_user()
selection", v2.

The kernel allows arches to select between inline and outline
implementations of the copy_{from,to}_user() by defining individual
INLINE_COPY_FROM_USER and INLINE_COPY_TO_USER, correspondingly.  However,
all arches enable or disable them always together.

Without the real use-case for one helper being inlined while the other
outlined, having independent controls is excessive and error prone.

The first patch of the series fixes rust/uaccess coppy_to_user() wrapper
guarded with INLINE_COPY_FROM_USER.  The 2nd patch switches codebase to
the unified INLINE_COPY_USER.  And the last patch cleans up ifdefery in
the include/linux/uaccess.h


This patch (of 3):

The copy_to_user() rust helper is only needed when the main kernel inlines
the function.  It is controlled by INLINE_COPY_TO_USER, but the rust
helper is protected with INLINE_COPY_FROM_USER.

Fix that.

Subject: [PATCH 2097/5214] uaccess: minimize INLINE_COPY_USER-related ifdefery

Now that we've got the same config selecting inline vs outline
copy_to_user() and copy_from_user(), we can simplify the corresponding
logic in the uaccess.h.

Link: https://lore.kernel.org/20260425020857.356850-4-ynorov@nvidia.com
Fixes: 1f9a8286bc0c ("uaccess: always export _copy_[from|to]_user with CONFIG_RUST")

Subject: [PATCH 2098/5214] kcov: refactor common handle ID into
 kcov_common_handle_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Store common handle IDs in "struct kcov_common_handle_id", which consumes
no space in non-KCOV builds.

This cleanup removes #ifdef boilerplate code from subsystems that
integrate with KCOV (in particular in usbip_common.h and skbuff.h, see the
diffstat).

This should also make it easier to add KCOV remote coverage to more
subsystems in the future.

Subject: [PATCH 2099/5214] rapidio/tsi721: prevent a bad dereference in
 tsi721_db_dpc()

With a list_for_each() loop, if we don't find the item we are looking for
in the list, then the loop exits with the iterator, which is "dbell" in
this loop, pointing to invalid memory.

This code uses the "found" variable to determine if we have found the
doorbell we are looking for or not.  However, the problem that the "found"
variable needs to be set to false at the start of each iteration,
otherwise after the first correct doorbell, then everything is marked as
found.

Reset the "found" to false at the start of the iteration and move the
variable inside the loop.

Subject: [PATCH 2101/5214] kfence: fix KASAN HW tags bypass via runtime
 sample_interval change

If a user writes a non-zero value to the sample_interval module parameter
at runtime, the missing KASAN HW tags check in the late init path allows
KFENCE to be enabled alongside KASAN HW tags, bypassing the boot
restriction.

This patch adds the missing check to param_set_sample_interval() to reject
the parameter change if KASAN HW tags are enabled.

Subject: [PATCH 2103/5214] gcov: use atomic counter updates to fix concurrent
 access crashes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GCC's GCOV instrumentation can merge global branch counters with loop
induction variables as an optimization.  In inflate_fast(), the inner copy
loops get transformed so that the GCOV counter value is loaded multiple
times to compute the loop base address, start index, and end bound.  Since
GCOV counters are global (not per-CPU), concurrent execution on different
CPUs causes the counter to change between loads, producing inconsistent
values and out-of-bounds memory writes.

The crash manifests during IPComp (IP Payload Compression) processing when
inflate_fast() runs concurrently on multiple CPUs:

  BUG: unable to handle page fault for address: ffffd0a3c0902ffa
  RIP: inflate_fast+1431
  Call Trace:
   zlib_inflate
   __deflate_decompress
   crypto_comp_decompress
   ipcomp_decompress [xfrm_ipcomp]
   ipcomp_input [xfrm_ipcomp]
   xfrm_input

At the crash point, the compiler generated three loads from the same
global GCOV counter (__gcov0.inflate_fast+216) to compute base, start, and
end for an indexed loop.  Another CPU modified the counter between loads,
making the values inconsistent - the write went 3.4 MB past a 65 KB
buffer.

Add -fprofile-update=prefer-atomic to CFLAGS_GCOV at the global level in
the top-level Makefile, guarded by a try-run compile test.  The test
compiles a minimal program with and without -fprofile-update=prefer-atomic
using the full KBUILD_CFLAGS, then compares undefined symbols in the
resulting object files.  If prefer-atomic introduces new undefined
references (such as __atomic_fetch_add_8 on i386 or __aarch64_ldadd8_relax
on arm64 with outline-atomics), the flag is not added -- the kernel does
not link against libatomic.

On architectures where GCC inlines 64-bit atomic counter updates (x86_64,
s390, ...) the test passes and the flag is enabled, preventing the
compiler from merging counters with loop induction variables and fixing
the observed concurrent-access crash.

On architectures where the flag would introduce libatomic dependencies, it
is silently omitted and behaviour is no worse than before this patch.

Move the CFLAGS_GCOV block from its original position (before the arch
Makefile include) to after the core KBUILD_CFLAGS assignments but before
the scripts/Makefile.gcc-plugins include.  This placement ensures the
try-run test sees arch-specific flags (-m32, -march=,
-mno-outline-atomics) while avoiding GCC plugin flags (-fplugin=) that
would break the test on clean builds when plugin shared objects do not yet
exist.

 ...

[CAUSE]
ocfs2_truncate_file() treats di_bh->i_size matching inode->i_size as an
internal code invariant and BUGs if it is broken.

That assumption is too strong for corrupted metadata. The dinode block can
still be structurally valid enough to pass ocfs2_read_inode_block() while
no longer matching an already-instantiated VFS inode. On local mounts,
ocfs2_inode_lock_update() skips refresh entirely, so truncate can
observe the mismatch directly and crash instead of rejecting the
corruption.

[FIX]
Turn the BUG_ON into normal OCFS2 corruption handling. If truncate sees
di_bh->i_size disagree with inode->i_size, report it with ocfs2_error() and
abort before touching truncate state.

This keeps the fix at the first boundary that actually requires the
sizes to match and avoids widening checks into hotter generic
inode-lock paths

 ...

[CAUSE]
ocfs2_journal_toggle_dirty() used to return -EIO when journal->j_bh no
longer contained a valid dinode, because the startup and shutdown paths
already handled that failure. Commit 10995aa2451a
("ocfs2: Morph the haphazard OCFS2_IS_VALID_DINODE() checks.") changed
the check to a BUG_ON() under the assumption that the journal dinode had
already been validated. That turns an unexpected invalid journal dinode
during mount teardown into a kernel crash instead of a normal mount
failure.

[FIX]
Replace the BUG_ON() with WARN_ON() and return -EIO. This keeps the
invariant warning for debugging, but restores the original behavior of
failing startup or shutdown cleanly instead of panicking the kernel.

Subject: [PATCH 2106/5214] ocfs2: validate inline xattr header before ibody
 lookups

Patch series "ocfs2: validate inline xattr header consumers".

Corrupt i_xattr_inline_size can move the computed inode-body xattr header
outside the dinode block. Several OCFS2 paths then trust xh_count or
xattr entry geometry from that unchecked header.

The reported KASAN splat hits the ibody lookup path:

  BUG: KASAN: use-after-free in ocfs2_xattr_find_entry+0x37b/0x3a0
  ocfs2_xattr_ibody_get()
  ocfs2_xattr_get_nolock()
  ocfs2_calc_xattr_init()

The same unchecked header derivation also exists in the outside-value
probe, ibody remove, inline refcount attach, and inline reflink paths.

This series factors the existing ibody list validation into a shared
helper and then converts the remaining inline-header consumers one at a
time.

Patch layout:

1. validate ibody get/find and reuse the helper in ibody list
2. validate the outside-value probe
3. validate ibody remove
4. validate inline refcount attach
5. validate inline reflink


This patch (of 5):

[BUG]
mknodat() can read past the end of a dinode block when ACL inheritance
walks a corrupted inode-body xattr header. Another report shows the same
unchecked lookup later faulting in the VFS open path after create
returns a garbage status.

[CAUSE]
ocfs2_xattr_ibody_list() already validates the inline xattr size and
entry count, but ocfs2_xattr_ibody_get() and ocfs2_xattr_ibody_find()
still derive the inline header directly from di->i_xattr_inline_size and
then trust xh_count. A corrupted inline size or entry count can therefore
move the computed header outside the dinode block before get/find start
walking it. That can either make ocfs2_xattr_find_entry() dereference
xs->header->xh_count outside the block or make ocfs2_xattr_get_nolock()
bubble a garbage status back through ocfs2_calc_xattr_init() into the
create/open path.

[FIX]
Factor the existing ibody header geometry checks into a shared helper.
Use it in ocfs2_xattr_ibody_get() and ocfs2_xattr_ibody_find(), and have
ocfs2_xattr_ibody_list() reuse the same helper instead of open-coding
the validation. Reject corrupt ibody metadata with -EFSCORRUPTED before
the lookup path can walk bogus xattr geometry or return a garbage status.

Subject: [PATCH 2107/5214] ocfs2: validate inline xattr header before checking
 outside values

[BUG]
A corrupt inline xattr header can make
ocfs2_has_inline_xattr_value_outside() walk xh_count from an unchecked
header while refcount-tree teardown decides whether inline xattrs still
point outside the inode body.

[CAUSE]
ocfs2_has_inline_xattr_value_outside() still computed the inline header
directly from di->i_xattr_inline_size and immediately iterated xh_count.
That is the same unchecked metadata boundary as the ibody lookup bug.

[FIX]
Reuse the shared inline-header helper before iterating xh_count. Because
this helper returns a boolean-style answer to its caller, treat a corrupt
header conservatively as "has outside values" instead of walking it.

Subject: [PATCH 2110/5214] ocfs2: validate inline xattr header before
 reflinking inline xattrs

[BUG]
A corrupt inline xattr header can make ocfs2_reflink_xattr_inline() lock,
copy, and reflink xattr state from an unchecked ibody xattr header.

[CAUSE]
The inline reflink path still trusted di->i_xattr_inline_size to compute
header_off, xh, and new_xh before handing the source header to the reflink
allocator and copy logic.

[FIX]
Validate the source inode's inline xattr header with the shared helper
first, then derive the reflink copy offsets from the validated inline
size/header. This keeps the reflink path from traversing corrupt ibody
xattr geometry.

Subject: [PATCH 2112/5214] lib/bug: cleanup comment style, types and modernize
 logging

Improve the overall code quality of lib/bug.c by:
- Reformatting the main documentation block to follow the standard
  kernel multi-line comment style.
- Replacing 'unsigned' with the preferred 'unsigned int'.
- Converting legacy printk() calls to modern pr_warn() and pr_info()
  macros to include proper facility levels and satisfy checkpatch.

Subject: [PATCH 2113/5214] selftests/perf_events: fix mmap() error check in
 sigtrap_threads

In sigtrap_threads(), the return value of mmap() is checked against NULL.
mmap() returns MAP_FAILED, which is (void *)-1, not NULL, when it fails.
Since MAP_FAILED is non-zero and non-NULL, the condition "p == NULL" will
never be true on failure, causing the program to proceed with an invalid
pointer and segfault if mmap() actually fails under memory pressure.

Subject: [PATCH 2114/5214] lib/tests: extend cmdline KUnit with next_arg()
 tests

The cmdline KUnit suite covers get_option() and get_options(), but it
does not exercise next_arg().

Extend the suite with one test for a quoted value containing spaces and
one regression test for a bare quote token after a normal parameter.

The regression test covers the bare quote token path fixed by commit
9847f21225c4 ("lib/cmdline: avoid page fault in next_arg").

Subject: [PATCH 2115/5214] lib: fix _parse_integer_limit() to handle overflow

Patch series "lib and lib/cmdline enhancements", v11.

This series is a merge of the recently posted [1] and [2].  The first one
is intended to adjust '_parse_integer_limit()' and 'memparse()' to not
ignore overflows, extend string to 64-bit integer conversion tests, add
KUnit-based test for 'memparse()' and fix kernel-doc glitches found in
lib/cmdline.c.  The second one was originated from RISCV-specific build
fixes needed to integrate the former and now aims to provide
platform-specific double-word shifts and corresponding KUnit test.

Getting feedback from RISCV core maintainers would be very helpful.

Special thanks to Andy Shevchenko, Charlie Jenkins, and Andrew Morton.


This patch (of 8):

In '_parse_integer_limit()', adjust native integer arithmetic with
near-to-overflow branch where 'check_mul_overflow()' and
'check_add_overflow()' are used to check whether an intermediate result
goes out of range, and denote such a case with ULLONG_MAX, thus making the
function more similar to standard C library's 'strtoull()'.  Adjust
comment to kernel-doc style as well.

Subject: [PATCH 2116/5214] lib: fix memparse() to handle overflow

Since '_parse_integer_limit()' (and so 'simple_strtoull()') is now capable
to handle overflow, adjust 'memparse()' to handle overflow (denoted by
ULLONG_MAX) returned from 'simple_strtoull()'.  Also use
'check_shl_overflow()' to catch an overflow possibly caused by processing
size suffix and denote it with ULLONG_MAX as well.

Subject: [PATCH 2117/5214] lib: add more string to 64-bit integer conversion
 overflow tests

Add a few more string to 64-bit integer conversion tests to check whether
'kstrtoull()', 'kstrtoll()', 'kstrtou64()' and 'kstrtos64()' can handle
overflows reported by '_parse_integer_limit()'.

Subject: [PATCH 2120/5214] riscv: add platform-specific double word shifts for
 riscv32

Add riscv32-specific '__ashldi3()', '__ashrdi3()', and '__lshrdi3()'.
Initially it was intended to fix the following link error observed when
building EFI-enabled kernel with CONFIG_EFI_STUB=y and
CONFIG_EFI_GENERIC_STUB=y:

riscv32-linux-gnu-ld: ./drivers/firmware/efi/libstub/lib-cmdline.stub.o: in function `__efistub_.L49':
__efistub_cmdline.c:(.init.text+0x1f2): undefined reference to `__efistub___ashldi3'
riscv32-linux-gnu-ld: __efistub_cmdline.c:(.init.text+0x202): undefined reference to `__efistub___lshrdi3'

Reported at [1] trying to build
https://patchew.org/linux/20260212164413.889625-1-dmantipov@yandex.ru,
tested with 'qemu-system-riscv32 -M virt' only.

Subject: [PATCH 2121/5214] lib: kunit: add tests for __ashldi3(), __ashrdi3(),
 and __lshrdi3()

Add KUnit tests for '__ashldi3()', '__ashrdi3()', and '__lshrdi3()' helper
functions used to implement 64-bit arithmetic shift left, arithmetic shift
right and logical shift right, respectively, on a 32-bit CPUs.

Tested with 'qemu-system-riscv32 -M virt' and 'qemu-system-arm -M virt'.

Subject: [PATCH 2122/5214] riscv: fix building compressed EFI image

When building vmlinuz.efi with CONFIG_EFI_ZBOOT enabled, '__lshrdi3()'
is also needed to fix yet another link error observed when building
riscv32 and loongarch32 images:

riscv32-linux-gnu-ld: drivers/firmware/efi/libstub/lib-cmdline.stub.o: in function `__efistub_.L49':
__efistub_cmdline.c:(.init.text+0x202): undefined reference to `__efistub___lshrdi3'

/usr/bin/loongarch32-linux-gnu-ld: ./drivers/firmware/efi/libstub/lib-cmdline.stub.o: in function `__efistub_.L47':
__efistub_cmdline.c:(.init.text+0x26c): undefined reference to `__efistub___lshrdi3'

And since both riscv64 and loongarch64 can have CONFIG_EFI_ZBOOT but
doesn't need these library routines, rely on CONFIG_32BIT to manage
linking of lib-ashldi3.o and lib-lshrdi3.o on 32-bit variants only.

Subject: [PATCH 2123/5214] kcov: allow simultaneous
 KCOV_ENABLE/KCOV_REMOTE_ENABLE

Allow the same userspace thread to simultaneously collect normal coverage
in syscall context (KCOV_ENABLE) and remote coverage of asynchronous work
created by the thread (KCOV_REMOTE_ENABLE).  With this, remote KCOV
coverage becomes useful for generic fuzzing and not just fuzzing of
specific data injection interfaces.

This requires that the task_struct::kcov_* fields are separated into ones
that are used by the task that generates coverage, and ones that are used
by the task that requested remote coverage.  To split this up:

 - Split task_struct::kcov into kcov and kcov_remote. kcov_task_exit() now
   has to clean up both separately.
 - Only use task_struct::kcov_mode on the task that generates coverage.
 - Only reset task_struct::kcov_handle on the task that requested remote
   coverage.

After this change, fields used by the task that generates coverage are:

 - kcov_mode
 - kcov_size
 - kcov_area
 - kcov
 - kcov_sequence
 - kcov_softirq

Fields used by the task that requested remote coverage are:

 - kcov_remote
 - kcov_handle

Subject: [PATCH 2125/5214] raid6: turn the userspace test harness into a kunit
 test

Patch series "cleanup the RAID6 P/Q library", v3.

This series cleans up the RAID6 P/Q library to match the recent updates to
the RAID 5 XOR library and other CRC/crypto libraries.  This includes
providing properly documented external interfaces, hiding the internals,
using static_call instead of indirect calls and turning the user space
test suite into an in-kernel kunit test which is also extended to improve
coverage.

Note that this changes registration so that non-priority algorithms are
not registered, which greatly helps with the benchmark time at boot time.
I'd like to encourage all architecture maintainers to see if they can
further optimized this by registering as few as possible algorithms when
there is a clear benefit in optimized or more unrolled implementations.


This patch (of 18):

Currently the raid6 code can be compiled as userspace code to run the test
suite.  Convert that to be a kunit case with minimal changes to avoid
mutating global state so that we can drop this requirement.

Note that this is not a good kunit test case yet and will need a lot more
work, but that is deferred until the raid6 code is moved to it's new
place, which is easier if the userspace makefile doesn't need adjustments
for the new location first.

From 3626738bc7147d52cb49f3994a9846aa2d34810a Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>
Date: Mon, 18 May 2026 07:17:46 +0200
Subject: [PATCH 2127/5214] raid6: move to lib/raid/

Move the raid6 code to live in lib/raid/ with the XOR code, and change the
internal organization so that each architecture has a subdirectory similar
to the CRC, crypto and XOR libraries, and fix up the Makefile to only
build files actually needed.

Also move the kunit test case from the history test/ subdirectory to
tests/ and use the normal naming scheme for it.

Subject: [PATCH 2131/5214] raid6: improve the public interface

Stop directly calling into function pointers from users of the RAID6 PQ
API, and provide exported functions with proper documentation and API
guarantees asserts where applicable instead.

Subject: [PATCH 2132/5214] raid6: warn when using less than four devices

Quoting H.  Peter Anvin who came up with the RAID6 P/Q algorithm, and who
wrote the initial implementation, then still part of the md driver:

  The RAID-6 code has *never* supported only 3 units, and if it ever
  worked for *any* of the implementations it was purely by accident.
  Speaking as the original author I should know; this was deliberate as
  in some cases the degenerate case (3) would have required extra trays
  in the code to no user benefit.

While md never allowed less than 4 devices, btrfs does.  This new warning
will trigger for such file systems, but given how it already causes havoc
that is a good thing.  If btrfs wants to fix third, it should switch to
transparently use three-way mirroring underneath, which will work as P and
Q are copies of the single data device by the definition of the Linux RAID
6 P/Q algorithm.

Subject: [PATCH 2133/5214] raid6: hide internals

Split out two new headers from the public pq.h:

 - lib/raid/raid6/algos.h contains the algorithm lists private to
   lib/raid/raid6
 - include/linux/raid/pq_tables.h contains the tables also used by
   async_tx providers.

The public include/linux/pq.h is now limited to the public interface for
the consumers of the RAID6 PQ API.

[hch@lst.de: remove duplicate ccflags-y line]

From adfcf6e89bc1322c4a6cc37ad32e411cf0500622 Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>
Date: Mon, 18 May 2026 07:17:53 +0200
Subject: [PATCH 2134/5214] raid6: rework registration of optimized algorithms

Replace the static array of algorithms with a call to an architecture
helper to register algorithms.  This serves two purposes: it avoid having
to register all algorithms in a single central place, and it removes the
need for the priority field by just registering the algorithms that the
architecture considers suitable for the currently running CPUs.

[hch@lst.de: register avx512 after avx2]

Subject: [PATCH 2138/5214] raid6_kunit: use KUNIT_CASE_PARAM

The raid6 test combines various generation and recovery algorithms.  Use
KUNIT_CASE_PARAM and provide a generator that iterates over the possible
combinations instead of looping inside a single test instance.

Subject: [PATCH 2139/5214] raid6_kunit: dynamically allocate data buffers
 using vmalloc

Use vmalloc for the data buffers instead of using static .data
allocations.  This provides for better out of bounds checking and avoids
wasting kernel memory after the test has run.  vmalloc is used instead of
kmalloc to provide for better out of bounds access checking as in other
kunit tests.

Subject: [PATCH 2140/5214] raid6_kunit: cleanup dataptr handling

Move the global dataptr array into test_recover() as all sites that fill
data or parity can use test_buffers directly, and this localized the
override for the failed slots to the recovery testing routine.

Subject: [PATCH 2141/5214] raid6_kunit: randomize parameters and increase
 limits

The current test has double-quadratic behavior in the selection for the
updated ("XORed") disks, and in the selection of updated pointers, which
makes scaling it to more tests difficult.  At the same time it only ever
tests with the maximum number of disks, which leaves a coverage hole for
smaller ones.

Fix this by randomizing the total number, failed disks and regions to
update, and increasing the upper number of tests disks.

Subject: [PATCH 2142/5214] raid6_kunit: randomize buffer alignment

Add code to add random alignment to the buffers to test the case where
they are not page aligned, and to move the buffers to the end of the
allocation so that they are next to the vmalloc guard page.

This does not include the recovery buffers as the recovery requires page
alignment.

- * cnt32_to_63 - Expand a 32-bit counter to a 63-bit counter
- * @cnt_lo: The low part of the counter
- *
- * Many hardware clock counters are only 32 bits wide and therefore have
- * a relatively short period making wrap-arounds rather frequent.  This
- * is a problem when implementing sched_clock() for example, where a 64-bit
- * non-wrapping monotonic value is expected to be returned.
- *
- * To overcome that limitation, let's extend a 32-bit counter to 63 bits
- * in a completely lock free fashion. Bits 0 to 31 of the clock are provided
- * by the hardware while bits 32 to 62 are stored in memory.  The top bit in
- * memory is used to synchronize with the hardware clock half-period.  When
- * the top bit of both counters (hardware and in memory) differ then the
- * memory is updated with a new value, incrementing it when the hardware
- * counter wraps around.
- *
- * Because a word store in memory is atomic then the incremented value will
- * always be in synch with the top bit indicating to any potential concurrent
- * reader if the value in memory is up to date or not with regards to the
- * needed increment.  And any race in updating the value in memory is harmless
- * as the same value would simply be stored more than once.
- *
- * The restrictions for the algorithm to work properly are:
- *
- * 1) this code must be called at least once per each half period of the
- *    32-bit counter;
- *
- * 2) this code must not be preempted for a duration longer than the
- *    32-bit counter half period minus the longest period between two
- *    calls to this code;
- *
- * Those requirements ensure proper update to the state bit in memory.
- * This is usually not a problem in practice, but if it is then a kernel
- * timer should be scheduled to manage for this code to be executed often
- * enough.
- *
- * And finally:
- *
- * 3) the cnt_lo argument must be seen as a globally incrementing value,
- *    meaning that it should be a direct reference to the counter data which
- *    can be evaluated according to a specific ordering within the macro,
- *    and not the result of a previous evaluation stored in a variable.
- *
- * For example, this is wrong:
- *
- *	u32 partial = get_hw_count();
- *	u64 full = cnt32_to_63(partial);
- *	return full;
- *
- * This is fine:
- *
- *	u64 full = cnt32_to_63(get_hw_count());
- *	return full;
- *
- * Note that the top bit (bit 63) in the returned value should be considered
- * as garbage.  It is not cleared here because callers are likely to use a
- * multiplier on the returned value which can get rid of the top bit
- * implicitly by making the multiplier even, therefore saving on a runtime
- * clear-bit instruction. Otherwise caller must remember to clear the top
- * bit explicitly.

Subject: [PATCH 2144/5214] ocfs2: kill osb->system_file_mutex lock

Commit 43b10a20372d ("ocfs2: avoid system inode ref confusion by adding
mutex lock") tried to avoid a refcount leak caused by allowing multiple
threads to call igrab(inode).  But addition of osb->system_file_mutex made
locking dependency complicated and is causing lockdep to warn about
possibility of AB-BA deadlock.

Since _ocfs2_get_system_file_inode() returns the same inode for the same
input arguments, we don't need to serialize
_ocfs2_get_system_file_inode().  What we need to make sure is that
igrab(inode) is called for only once().  Therefore, replace
osb->system_file_mutex with cmpxchg()-based locking.

debugfs_create_file() returns an error pointer on failure, never NULL, so

Subject: [PATCH 2146/5214] ocfs2: reject dinodes with non-canonical i_mode
 type

Patch series "ocfs2: harden inode validators against forged metadata", v2.

This series adds three structural checks to OCFS2 dinode validation so
malformed on-disk fields are rejected before ocfs2_populate_inode() copies
them into the in-core inode.

The checks cover:

  - i_mode values whose type bits do not name a canonical POSIX file
    type;
  - non-device dinodes whose id1.dev1.i_rdev field is non-zero; and
  - non-inline dinodes that claim non-zero i_size while i_clusters is
    zero, covering directories unconditionally and regular files on
    non-sparse volumes.

The normal read path reports these through ocfs2_error(), matching the
existing suballoc-slot, inline-data, chain-list, and refcount checks.  The
online filecheck path uses the same structural predicates but keeps its
own reporting contract, returning OCFS2_FILECHECK_ERR_INVALIDINO instead
of calling ocfs2_error().


This patch (of 3):

ocfs2_validate_inode_block() currently accepts any non-zero i_mode value.
ocfs2_populate_inode() then copies that mode verbatim into inode->i_mode
and dispatches on i_mode & S_IFMT to the file/dir/symlink/special_file
iops; an unrecognised type falls through to ocfs2_special_file_iops and
init_special_inode().

Reject dinodes whose type bits do not name one of the seven canonical
POSIX file types.  Use fs_umode_to_ftype(), the same generic file-type
conversion helper OCFS2 already uses for directory entries, so the
accepted inode type set matches the kernel file-type vocabulary instead of
open-coding a local switch.

Apply the same structural check to the online filecheck read path.
filecheck keeps its own error namespace, so it reports malformed i_mode
through the filecheck logger and OCFS2_FILECHECK_ERR_INVALIDINO instead of
calling ocfs2_error(), but it must not allow a malformed dinode to proceed
into ocfs2_populate_inode().

Subject: [PATCH 2147/5214] ocfs2: reject dinodes whose i_rdev disagrees with
 the file type

id1.dev1.i_rdev is the device-number arm of the ocfs2_dinode id1 union.
It is only meaningful for character and block device inodes.  For any
other user-visible file type the on-disk value must be zero.

ocfs2_populate_inode() currently copies id1.dev1.i_rdev into inode->i_rdev
before the S_IFMT switch decides whether the inode is a special file.  A
non-device inode with a non-zero i_rdev can therefore publish stale or
attacker-controlled device state into the in-core inode.

System inodes legitimately use other arms of the same union, so keep the
cross-check restricted to non-system inodes.  Factor that predicate into a
helper and use it in both the normal validator and online filecheck path;
filecheck reports the malformed dinode through
OCFS2_FILECHECK_ERR_INVALIDINO instead of ocfs2_error().

Subject: [PATCH 2148/5214] ocfs2: reject non-inline dinodes with i_size and
 zero i_clusters

On a volume mounted without OCFS2_FEATURE_INCOMPAT_SPARSE_ALLOC, a
non-inline regular file with non-zero i_size and zero i_clusters is
structurally malformed: the extent map declares no allocated clusters yet
the size header claims content exists.  Keep rejecting that shape, but
express it through a shared predicate so the same invariant is available
to normal inode reads and online filecheck.

The same zero-cluster shape is also malformed for non-inline directories.
ocfs2 directory growth allocates backing storage before advancing i_size,
and ocfs2_dir_foreach_blk_el() later walks until ctx->pos reaches
i_size_read(inode).  A forged directory dinode with a huge i_size and no
clusters would repeatedly fail on holes while advancing through the
claimed size.

Sparse regular files remain exempt: on sparse-alloc volumes, truncate can
legitimately grow i_size without allocating clusters.  System inodes and
inline-data dinodes also retain their separate storage rules.

Mirror the check in ocfs2_filecheck_validate_inode_block() as well.
filecheck reports through its own error namespace, so malformed
size/cluster state is logged as a filecheck invalid-inode result rather
than via ocfs2_error(), but it must not proceed into
ocfs2_populate_inode().

Subject: [PATCH 2149/5214] lib/uuid_kunit: add tests for the four random
 UUID/GUID generators

uuid_kunit currently exercises only guid_parse() and uuid_parse() (plus
their invalid-input paths).  The four random generators exported from
lib/uuid.c -- generate_random_uuid(), generate_random_guid(), uuid_gen()
and guid_gen() -- have no direct kunit coverage.

Random output cannot be compared against a fixed expected value, but RFC
4122 section 4.4 specifies two invariants that any version-4 random
UUID/GUID must satisfy:

  - version 4 in the high nibble of the version byte
    (byte 6 in the wire uuid_t layout, byte 7 in the byte-swapped
    guid_t layout);
  - variant DCE 1.1 (binary 10x) in the high bits of byte 8.

Add four test cases that invoke each generator several times and verify
these bit patterns hold.  The same checks catch a regression in either the
mask/OR sequence in the generators or the layout constants.  Run the loop
a handful of times to cover the small but non-zero chance that an unmasked
random byte happens to satisfy the version/variant pattern by accident on
a single call.

Subject: [PATCH 2151/5214] lib/nmi_backtrace: print out the CPUs which fail to
 respond to NMI

When debugging RCU stall cases, usually all CPUs will respond to the NMI
and print out the backtrace.  But in some nasty or hardware related cases,
some CPUs may fail to respond in 10 seconds, and very likely this is sign
of severe issues.

Paul McKenney has implemented the NMI backtrace stall check for x86, and
for other architectures, it should be also helpful to at least print out
those CPUs which failed to repond to the NMI, so that users can get an
early heads-up for possible CPU hard stall.

Subject: [PATCH 2153/5214] soundwire: dmi-quirks: Disable ghost Realtek
 devices

Many systems ship with a Realtek audio codec in the ACPI that doesn't
physically exist in the system. This confuses the newer function
topology system that creates the soundcard, as it builds the card based
on the ACPI information.

Whilst we are working with the laptop vendors to try and stop this
happening there are quite a few systems where this has shipped. Add a
quirk to disable this "ghost" device.

Currently this patch should cover:
 - Asus UX5406AA
 - Lenovo Yoga Pro 9i (83SF)
 - Lenovo Yoga Slim 7 Ultra (83QK)

Subject: [PATCH 2154/5214] iio: adc: ad_sigma_delta: fix CS held asserted and
 state leaks

In ad_sigma_delta_single_conversion(), set_mode(AD_SD_MODE_IDLE) and
disable_one() were called from the out: block while keep_cs_asserted
was still true. This caused any SPI transfer issued by those callbacks
to carry cs_change=1, leaving CS permanently asserted after the
conversion. Fix by moving both calls into the out_unlock: block, after
keep_cs_asserted is cleared, matching the pattern already used in
ad_sd_calibrate().

In the error path of ad_sd_buffer_postenable(), if an operation fails
after set_mode(AD_SD_MODE_CONTINUOUS) has already succeeded (e.g.
spi_offload_trigger_enable()), the device is left in continuous
conversion mode with CS physically asserted. Additionally,
bus_locked remaining true after spi_bus_unlock() causes subsequent
SPI operations to call spi_sync_locked() without the bus lock actually
held, allowing concurrent SPI access.

Fix the error path by clearing keep_cs_asserted first, then calling
set_mode(AD_SD_MODE_IDLE) to revert the device mode and deassert CS,
then clearing bus_locked before releasing the bus.

For devices that implement neither set_mode nor disable_one (such as
MAX11205, which has no physical CS pin), no SPI transfer is issued
during cleanup and the cs_change flag has no effect on any physical
line.

Subject: [PATCH 2155/5214] iio: adc: ad_sigma_delta: fix clear_pending_event
 for registerless devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ad_sigma_delta_clear_pending_event() falls through to the status register
read path for devices with has_registers = false and no rdy_gpiod. For
such devices, ad_sd_read_reg() skips the address byte entirely and clocks
raw MISO bytes with no address phase — making it byte-for-byte identical
to reading conversion data. If a pending conversion result is present,
this partially consumes it and corrupts the data stream for the subsequent
ad_sd_read_reg() call in ad_sigma_delta_single_conversion().

Furthermore, with num_resetclks = 0 on these devices, data_read_len
evaluates to 0. If the clocked byte has bit 7 clear, pending_event is set
and the code attempts memset(data + 2, 0xff, 0 - 1), overflowing to
SIZE_MAX and corrupting the heap.

Fix by returning 0 immediately when neither rdy_gpiod nor has_registers
is set. This is safe for all current registerless devices: ad7191 and
ad7780 (with powerdown GPIO) are reset between conversions by CS
deassertion, so there is no stale result to drain; ad7780 (without
powerdown GPIO) and max11205 are continuously-converting and cycle ~DRDY
at the output data rate regardless of whether the previous result was
read, so the next falling edge fires naturally.

A future registerless device that holds ~DRDY asserted until data is read
would be broken by this early return and would require either
num_resetclks set or a rdy-gpio.

The same heap corruption is reachable on any device with rdy_gpiod set
but num_resetclks = 0: if the GPIO indicates a pending event, the drain
path executes memset(data + 2, 0xff, 0 - 1) regardless of has_registers.
Add an explicit data_read_len == 0 guard after the pending event check;
the stale result is then consumed by the first ad_sd_read_reg() call in
ad_sigma_delta_single_conversion().

Subject: [PATCH 2157/5214] gfs2: page poisoning fix

Processes can write to the last page of a file using mmap, and when the file
size is not a multiple of the page size, this can be used to write beyond the
end of the file.  This is sometimes referred to as page poisoning, and it is
not a problem in itself because the data beyond eof will be ignored.  However,
we currently fail to clear out any space beyond the end of the file that we
skip over when the file size is increased, so that "poison" can end up getting
exposed.  Fix that.

Subject: [PATCH 2158/5214] coresight: etb10: restore atomic_t for shared
 reading state

The etb10 miscdevice uses drvdata->reading as a shared exclusivity gate
for userspace buffer access. etb_open() claims that gate with
local_cmpxchg(), and etb_release() clears it with local_set().

That gate is shared per-device state rather than CPU-local state. A
running system can reach it whenever /dev/<etb> is opened, closed, and
reopened by different tasks while the device remains registered, so the
same drvdata->reading variable may be claimed on one CPU and later
cleared on another.

This code used to use atomic_t for the same gate, but commit
27b10da8fff2 ("coresight: etb10: moving to local atomic operations")
changed it to local_t even though the access pattern remained cross-task
and cross-CPU. Restore atomic_t together with atomic_cmpxchg() and
atomic_set() so the exclusivity gate again uses a primitive intended
for shared state.

The issue was found on Linux v6.18.21 by our static analysis tool while
scanning surviving local_t-on-shared-state sites, and then manually
reviewed against the live etb10 file-op path.

It was runtime-validated with a reproducible QEMU no-device KCSAN PoC
that kept the same report-local contract:

  1. use one shared struct etb_drvdata carrier and its
     drvdata->reading gate;
  2. call etb_open() and etb_release() sequentially on that gate to
     confirm the original claim/clear path;
  3. bind the open side to CPU0 and the release side to CPU1 for the
     same gate to show cross-CPU ownership;
  4. run bound workers that repeatedly race etb_open() and
     etb_release() on the same gate until KCSAN reports a target hit.

The harness recorded:

This no-device harness is not a real ETB10 hardware end-to-end run, but
it preserves the same shared drvdata->reading gate and the same
etb_open()/etb_release() claim/clear contract. No real ETB10 hardware
was available for runtime testing.

Build-tested with:
  make olddefconfig
  make -j"$(nproc)" drivers/hwtracing/coresight/coresight-etb10.o

Subject: [PATCH 2159/5214] perf session: Add minimum event size and alignment
 validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a per-type minimum size table (perf_event__min_size[]) and
enforce it before swap and processing, so that both cross-endian
and native-endian paths are protected from accessing fields past
the event boundary.

The table uses offsetof() for types with trailing variable-length
fields (filenames, strings, msg arrays) and sizeof() for
fixed-size types.  Zero entries mean no minimum beyond the 8-byte
header already enforced by the reader.

Undersized events are skipped with a warning in process_event
and rejected in peek_event — both checked before the swap
handler runs, preventing OOB access on crafted event fields.

Also reject events whose header.size is not 8-byte aligned.  The
kernel aligns all event sizes to sizeof(u64) — see
perf_event_comm_event() (ALIGN), perf_event_mmap_event(),
perf_event_cgroup(), perf_event_ksymbol() (IS_ALIGNED loops),
and perf_event_text_poke() (ALIGN) in kernel/events/core.c.
An unaligned size means the file is corrupted or crafted; reject
early so downstream code that divides by sizeof(u64) to compute
array element counts gets exact results.

Three legacy user events are exempted from the alignment check:
TRACING_DATA (66) had a 12-byte struct before commit b39c915a4f36
("libperf event: Ensure tracing data is multiple of 8 sized")
added padding, COMPRESSED (81) carries raw ZSTD output (already
superseded by COMPRESSED2 with PERF_ALIGN), and HEADER_FEATURE
(80) uses do_write_string() with a 4-byte length prefix.

Also guard event_swap() against crafted event types >=
PERF_RECORD_HEADER_MAX to prevent OOB reads on the
perf_event__swap_ops[] array.

Changes in v2:
- Fix double-skip for unsupported event types: return 0 instead
  of event->header.size in perf_session__process_event() for
  HEADER_MAX, since reader__read_event() already advances by
  event->header.size (Reported-by: sashiko-bot@kernel.org)
- Exempt TRACING_DATA, COMPRESSED, and HEADER_FEATURE from the
  alignment check — these legacy user events predate the 8-byte
  alignment rule (Reported-by: sashiko-bot@kernel.org)
- peek_event: return 0 (skip) for unknown event types instead of
  -1 (error), consistent with process_event which already skips
  unsupported types gracefully (Reported-by: sashiko-bot@kernel.org)

Subject: [PATCH 2160/5214] perf session: Bounds-check one_mmap event pointer
 in peek_event

perf_session__peek_event() computes an event pointer directly from
file_offset when one_mmap is active, without verifying that file_offset
and the subsequent event->header.size fall within the mapped region.
A corrupted perf.data file could cause out-of-bounds memory reads.

Add one_mmap_size to the session struct and validate both the header
and full event fit within the mmap before dereferencing.

Subject: [PATCH 2161/5214] perf tools: Fix event_contains() macro to verify
 full field extent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

event_contains() checked whether a field's start offset was within
the event (header.size > offsetof), but not whether the full field
fit.  A crafted event with header.size = offsetof(field) + 1 would
pass the check, but an 8-byte access (bswap_64, direct read) would
overrun the event boundary by up to 7 bytes.

Fix the macro to verify the complete field:

  header.size >= offsetof(field) + sizeof(field)

Also update all callers that check event_contains(time_cycles) but
access later fields (time_mask, cap_user_time_zero,
cap_user_time_short) to check for cap_user_time_short — the last
field accessed — so the entire extended block is verified:
tsc.c, arm-spe.c, cs-etm.c, jitdump.c.

Note: session.c's perf_event__time_conv_swap() also guards on
time_cycles but accesses time_mask — a pre-existing issue not
introduced by this macro change.  It is fixed by a later patch
in this series ("perf session: Add validated swap
infrastructure with null-termination checks"), which decouples
time_cycles and time_mask into independent per-field
event_contains() checks.  The struct assignment overread
(session->time_conv = event->time_conv copies sizeof on a
potentially shorter event) is separately fixed by "perf
session: Use bounded copy for PERF_RECORD_TIME_CONV".

Subject: [PATCH 2162/5214] perf zstd: Fix compression error path in
 zstd_compress_stream_to_records()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The error fallback does memcpy(dst, src, src_size) intending to store
uncompressed data when compression fails, but this has three bugs:

1. dst has been advanced past the record header (and potentially
   past earlier compressed records), so the copy writes to the
   wrong offset in the output buffer.

2. src still points to the start of the input, not to the
   remaining uncompressed data at src + input.pos.  On a second
   or later iteration, previously compressed data would be
   duplicated.

3. No check that dst_size >= src_size — if the remaining output
   space is smaller, this is an out-of-bounds write.

Replace with return -1 after resetting the ZSTD compression
context via ZSTD_initCStream().  The -1 propagates through
zstd_compress() -> record__pushfn() -> perf_mmap__push() to the
recording loop, which breaks out and terminates recording.

Add an out_child_no_flush label in __cmd_record() so the
mmap-read failure path skips the final record__mmap_read_all()
flush — retrying the same read that just failed would just fail
again, and the flush is only useful when the mmap data is intact
but the control path (auxtrace, switch_output) had an error.

Consolidate all error paths through a single 'reset' label to
ensure the compression context is always reset on failure —
including the output-buffer-full path, where a bare return
without resetting would leave stale stream state that corrupts
output if the caller retries.

Also guard against process_header() writing the event header
before the buffer-full check: add a sizeof(perf_event_header)
pre-check so the callback never writes past the output buffer.

Guard against ZSTD making no progress: if output.pos is zero
after ZSTD_compressStream(), calling process_header(record, 0)
would re-trigger header initialization, double-subtracting the
header size from dst_size and underflowing the unsigned counter.

Also fix two pre-existing issues in the same function:

- Add a dst_size guard before subtracting the record header
  size: if the output buffer is nearly full, the unsigned
  dst_size -= size underflows to a huge value, causing
  ZSTD_compressStream to write past the buffer boundary.

- Check the ZSTD_initCStream() return value and log an error
  if the context reset itself fails.

Subject: [PATCH 2163/5214] perf zstd: Fix multi-iteration decompression and
 error handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

zstd_decompress_stream() has two bugs in its multi-iteration loop:

1. After each ZSTD_decompressStream() call, the code advances
   output.dst by output.pos but doesn't reset output.pos to 0.
   ZSTD interprets output.pos relative to output.dst, so the
   next iteration writes at (dst + pos) + pos = dst + 2*pos,
   skipping a gap and potentially writing out of bounds.

2. On ZSTD_decompressStream() error, the loop executes break
   and returns output.pos (which is > 0 if some bytes were
   decompressed before the error).  The caller checks
   !decomp_size and skips the error, silently accepting
   truncated or corrupted data.

Fix both by removing the output buffer adjustment — ZSTD
correctly accumulates output.pos across calls without it.
Return 0 on decompression error so the caller detects it.
Add a no-progress guard to prevent infinite loops if the
output buffer fills before all input is consumed.

Note: the compressed event data_size is validated against
header.size by a subsequent patch in this series
("perf tools: Harden compressed event processing").

Subject: [PATCH 2164/5214] perf session: Fix PERF_RECORD_READ swap and dump
 for variable-length events

The kernel dynamically sizes PERF_RECORD_READ based on
attr.read_format: only the fields enabled by PERF_FORMAT_TOTAL_TIME_ENABLED,
PERF_FORMAT_TOTAL_TIME_RUNNING, PERF_FORMAT_ID, and PERF_FORMAT_LOST
are emitted, packed with no gaps.

perf_event__read_swap() unconditionally byte-swapped time_enabled,
time_running, and id at their fixed struct offsets, causing
out-of-bounds access on smaller events and swapping the wrong
bytes when not all format fields are present.  It also swapped
sample_id_all at a fixed offset past the full struct, which is
wrong for shorter events.

Replace the individual field swaps with a single mem_bswap_64()
over the entire tail from value onward.  Since every field after
pid/tid is u64 regardless of which combination is present, this
correctly handles any read_format combination and any trailing
sample_id_all fields.

Similarly, dump_read() accessed optional fields via fixed struct
offsets, displaying values from wrong positions when not all
format bits are set.  Walk the packed u64 array sequentially
instead, with bounds checks against event->header.size.

Subject: [PATCH 2165/5214] perf session: Fix swap_sample_id_all() crash on
 crafted events

swap_sample_id_all() calls BUG_ON(size % sizeof(u64)) which kills
perf on any event where the sample_id_all tail is not 8-byte aligned.
A crafted perf.data can trigger this trivially.

Replace BUG_ON with a bounds check: skip the swap if the data pointer
is past the end of the event, and only swap when there are bytes
remaining.

Note: the strlen calls in string-field swap handlers (comm,
mmap, mmap2, cgroup) are replaced with bounded strnlen by the
next patch in this series ("perf session: Add validated swap
infrastructure with null-termination checks").

From 981f13ae6255fe8e9e68ca6435cd8194446460ec Mon Sep 17 00:00:00 2001

Subject: [PATCH 2166/5214] perf session: Add validated swap infrastructure
 with null-termination checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change swap callbacks from void to int return so handlers can
propagate errors.  All 28 existing handlers are converted to
return 0 on success, -1 on error.  Three new handlers (KSYMBOL,
BPF_EVENT, HEADER_FEATURE) are added returning int from the
start, with sample_id_all handling for the kernel event types.

event_swap() propagates the return to its callers (process_event
and peek_event), which skip events that fail to swap.

Add perf_event__check_nul() for null-termination enforcement
on the common event delivery path for MMAP, MMAP2, COMM,
CGROUP, and KSYMBOL events.  Events with
unterminated strings are skipped — native-endian files are
mapped read-only, so writing a NUL byte in place would segfault.

Swap handler hardening:

 - Use strnlen bounded by event size (instead of strlen) in
   COMM/MMAP/MMAP2/CGROUP swap handlers, returning -1 on
   unterminated strings.

 - Bounds check text_poke old_len+new_len before computing the
   sample_id offset, returning -1 on overflow.  Use offsetof()
   for the native-path check in machines__deliver_event() since
   sizeof() includes struct padding past the flexible array.

 - Fix PERF_RECORD_SWITCH sample_id_all: non-CPU_WIDE SWITCH
   events have sample_id immediately after the 8-byte header,
   not at sizeof(struct perf_record_switch) which is the
   CPU_WIDE variant size.

 - Fix perf_event__time_conv_swap(): decouple time_cycles and
   time_mask into independent per-field event_contains() checks,
   so each field is only swapped when the event is large enough
   to contain it.  The original code guarded both fields under
   a single time_cycles check, which would swap time_mask on a
   short event that contains time_cycles but not time_mask.

 - Handle ABI0 (attr.size == 0) in perf_event__attr_swap()
   by substituting PERF_ATTR_SIZE_VER0, so bswap_safe()
   correctly swaps VER0 fields instead of skipping everything.

 - peek_events: on swap failure, advance past the malformed
   entry instead of aborting the loop.

Note: the nr-field bounds checks for namespaces, thread_map,
cpu_map, and stat_config arrays are added by a subsequent
patch ("perf session: Validate nr fields against event size
on both swap and common paths").  The HEADER_ATTR attr.size
validation is added by ("perf session: Validate HEADER_ATTR
attr.size before swapping").

By establishing the int-returning swap infrastructure first,
all subsequent hardening patches can use direct error returns
from day one — no poison values, no workarounds for void return.

Changes in v2:
- peek_events: abort instead of skip for AUXTRACE events on
  validation failure — skipping only header.size would land
  inside the raw trace payload, causing subsequent iterations
  to misparse data as events (Reported-by: sashiko-bot@kernel.org)

Fixes: 9aa0bfa370b2 ("perf tools: Handle PERF_RECORD_KSYMBOL")
Fixes: 45178a928a4b ("perf tools: Handle PERF_RECORD_BPF_EVENT")
Fixes: e9def1b2e74e ("perf tools: Add feature header record to pipe-mode")

Subject: [PATCH 2167/5214] perf session: Use bounded copy for
 PERF_RECORD_TIME_CONV

session->time_conv = event->time_conv copies sizeof(struct
perf_record_time_conv) bytes unconditionally, but older kernels
emit shorter TIME_CONV events without the time_cycles, time_mask,
cap_user_time_zero, and cap_user_time_short fields.

For a 32-byte event (the original format), this reads 24 bytes
past the event boundary into adjacent mmap'd data.  The garbage
values end up in session->time_conv and can cause incorrect TSC
conversion if cap_user_time_zero happens to be non-zero.

Replace the struct assignment with a bounded memcpy capped at
event->header.size, zeroing the remainder so extended fields
default to off when absent.

Subject: [PATCH 2168/5214] perf session: Validate HEADER_ATTR attr.size before
 swapping

Harden PERF_RECORD_HEADER_ATTR handling against crafted perf.data:

- Validate attr.size: must be >= PERF_ATTR_SIZE_VER0, a multiple
  of sizeof(u64), and fit within the event payload.
- Copy only min(attr.size, sizeof(struct perf_event_attr)) bytes
  into a local attr, zeroing the rest so legacy files don't leak
  adjacent event data into new fields.
- Keep the original attr.size so perf_event__synthesize_attr()
  uses it for both allocation and ID-array placement.

Fix perf_event__synthesize_attr() to use attr->size (not the
compiled sizeof) for event allocation and layout, so perf inject
correctly re-synthesizes attrs from files recorded by a different
perf version.  Without this, the ID array destination pointer
(computed via perf_record_header_attr_id()) would be inconsistent
with the allocation when attr->size differs from sizeof.

Also fix the parse-no-sample-id-all test to set attr.size, which
is now validated, and improve error handling in read_attr() for
short reads and invalid attr sizes.

Handle ABI0 pipe/inject events where attr.size is 0: use a local
attr_size variable set to PERF_ATTR_SIZE_VER0 for both the bounded
copy and ID array position, instead of writing back to the event.
Native-endian files may be MAP_SHARED (read-only mmap), so writing
to the event buffer would SIGSEGV.  The swap path handles ABI0 in
perf_event__attr_swap() which writes to the MAP_PRIVATE copy.

header.size alignment is now validated centrally in
perf_session__process_event() (see "Add minimum event size and
alignment validation").

Subject: [PATCH 2169/5214] perf session: Validate nr fields against event size
 on both swap and common paths
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Several event types use an nr field to control iteration over
variable-length arrays.  The swap handlers byte-swap and loop using
these fields without bounds checks, and the native processing path
trusts them as well.

Add bounds checks on both paths for:

- PERF_RECORD_THREAD_MAP: validate nr against payload, return -1
  on the swap path.  On the native path, reject with -EINVAL.

- PERF_RECORD_NAMESPACES: clamp nr on the swap path (safe because
  each entry is indexed by type; missing entries just won't be
  resolved).  Skip the event on the native path.

- PERF_RECORD_CPU_MAP: clamp nr for CPUS and MASK sub-types on
  the swap path.  Add bounds checks for mask64 which previously
  had no nr validation.  Skip the event on the native path.

- PERF_RECORD_STAT_CONFIG: clamp nr on the swap path (safe because
  each config entry is self-describing via its tag).  Skip the
  event on the native path.

The swap path (cross-endian, writable MAP_PRIVATE mapping) can
safely clamp by writing back to the event.  The native path
(read-only MAP_SHARED mapping) must skip instead of clamping
because writing to the mmap'd event would segfault.

Also fix stat_config swap range: change size += 1 to
size += sizeof(event->stat_config.nr) for clarity.  The old +1
happened to work because mem_bswap_64 processes 8-byte chunks,
but the intent is to include the 8-byte nr field in the swap
range.

Changes in v2:
- Document that PERF_RECORD_NAMESPACES max_nr includes trailing
  sample_id space when sample_id_all is present — harmless on the
  swap path because both per-element bswap_64 and swap_sample_id_all()
  perform the same u64 byte swap (Reported-by: sashiko-bot@kernel.org)

Subject: [PATCH 2170/5214] perf header: Byte-swap build ID event pid and
 bounds check section entries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

perf_header__read_build_ids() swaps the event header fields for cross-endian
perf.data files but not bev.pid. This causes perf_session__findnew_machine()
to look up the wrong machine for guest VM build IDs, misattributing them.
Swap bev.pid alongside the header fields.

Also add a build_id_swap callback for stream-mode build ID events,
and validate NUL-termination of build_id.filename on the native-endian
delivery path (perf_session__process_user_event) — events with
unterminated filenames are skipped.

Harden perf_header__read_build_ids() against crafted perf.data files:

- Add overflow check on offset + size to prevent wrap past ULLONG_MAX.
- Reject bev.header.size == 0 which would loop forever.
- Reject bev.header.size > remaining section to prevent reading past
  the section boundary.
- Guard memcmp(filename, "nel.kallsyms]", 13) with len >= 13 to avoid
  reading uninitialized stack memory on short filenames.
- Force NUL-termination of filename before passing it to functions
  like machine__findnew_dso() that use strlen/strcmp.

Subject: [PATCH 2171/5214] perf cpumap: Reject RANGE_CPUS with start_cpu >
 end_cpu
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cpu_map__from_range() computes nr_cpus as end_cpu - start_cpu + 1.
When a crafted perf.data has start_cpu > end_cpu, this wraps to a
huge value, causing perf_cpu_map__empty_new() to attempt a massive
allocation.

Return NULL when the range is inverted.

Also clamp any_cpu to boolean (0 or 1) since it is added to the
allocation count — a crafted value > 1 would inflate the map size.

Harden cpu_map__from_mask() to reject unsupported long_size values
(anything other than 4 or 8), preventing misinterpretation of the
mask data layout.

Snapshot mmap'd fields via READ_ONCE() into locals to prevent
TOCTOU re-reads — the data pointer references MAP_SHARED mmap'd
memory that could theoretically change between reads on a
FUSE-backed file:

- cpu_map__from_range(): snapshot start_cpu, end_cpu, any_cpu
- cpu_map__from_entries(): snapshot nr and each cpu[i] element
- cpu_map__from_mask(): snapshot long_size (before validation,
  closing the check-then-read gap), mask_nr
- perf_record_cpu_map_data__read_one_mask(): add u16 long_size
  parameter so callers pass the validated copy instead of
  re-reading data->mask32_data.long_size from mmap'd memory

Subject: [PATCH 2172/5214] perf auxtrace: Harden auxtrace_error event handling

Fix four issues in PERF_RECORD_AUXTRACE_ERROR handling:

1. auxtrace_error_name() takes a signed int parameter, but e->type
   is __u32.  A crafted value like 0xFFFFFFFF converts to -1, passes
   the bounds check, and causes a negative array index.  Fix by
   changing the parameter to unsigned int.

2. The msg field is printed via %s without a length bound.  The
   min_size table only guarantees fields up to msg (offset 48), so
   a truncated event has zero msg bytes within the event boundary.
   Compute the available msg length from header.size, cap at
   sizeof(e->msg), and use %.*s.

3. fmt >= 2 adds machine_pid and vcpu fields after msg[64].  Older
   files may have fmt >= 2 but an event size that doesn't include
   these fields.  Add a size check in the swap handler to downgrade
   fmt before the conditional field access, and a matching size
   guard in the fprintf path for native-endian events (which are
   mmap'd read-only and can't be modified in place).

4. python_process_auxtrace_error() had the same issues: msg was
   passed to tuple_set_string() unbounded, and machine_pid/vcpu
   were accessed unconditionally without checking fmt or event
   size.  Apply the same bounds checks.

Subject: [PATCH 2173/5214] perf session: Add byte-swap and bounds check for
 PERF_RECORD_BPF_METADATA events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PERF_RECORD_BPF_METADATA has no entry in perf_event__swap_ops[], so its
nr_entries field is never byte-swapped when reading a cross-endian
perf.data file.  Downstream processing in
perf_event__fprintf_bpf_metadata() loops over nr_entries, so a
foreign-endian value causes out-of-bounds reads.

Add a swap handler that byte-swaps nr_entries after validating that
header.size is large enough.  The entries[] array contains only char
arrays (key/value strings), so no per-entry swap is needed — but ensure
NUL-termination on the writable cross-endian path.

Validate header.size, nr_entries, and string NUL-termination in the
common event delivery path so that native-endian files with malicious
values are also rejected.  Snapshot nr_entries via READ_ONCE() before
validation — the event is on a MAP_SHARED mmap that could theoretically
change between the bounds check and the loop.

Changes in v2:
- Snapshot event->header.size via READ_ONCE() into a local variable
  to prevent a double-fetch underflow in the max_entries calculation
  (Reported-by: sashiko-bot@kernel.org)
- Write back clamped nr_entries to the event on the swap path,
  consistent with NAMESPACES and STAT_CONFIG handlers — without
  writeback the native path sees the inflated nr and skips the
  event entirely (Reported-by: sashiko-bot@kernel.org)

Subject: [PATCH 2174/5214] perf header: Validate null-termination in
 PERF_RECORD_EVENT_UPDATE string fields
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

strdup(ev->unit) and strdup(ev->name) read until '\0' with no
guarantee the string is null-terminated within event->header.size.
The dump_trace fprintf path has the same problem with %s.

Validate before either path runs — same class of bug fixed for
MMAP/MMAP2/COMM/CGROUP by perf_event__check_nul().

Also harden the event_update swap handler to:
- Validate SCALE event size before swapping the double at
  offset 24, which exceeds the 24-byte min_size.
- Validate CPUS event size before accessing the cpu_map
  type/nr/long_size fields, which also start at the min_size
  boundary.
- Swap CPUS variant fields (type, nr, long_size) so the
  processing path sees native byte order.

Add validation in perf_event__process_event_update() for all
event update variants (UNIT, NAME, SCALE, CPUS) before
dump_trace or processing.

Validate CPUS nr against payload size for both PERF_CPU_MAP__CPUS
and PERF_CPU_MAP__MASK types on the fprintf (dump_trace) path:
- CPUS: check nr does not exceed available cpu entries
- MASK: check nr does not exceed available mask entries for
  both mask32 (long_size == 4) and mask64 (long_size == 8)
  layouts, with underflow guards on the offsetof subtraction

Fix a missing break before the default case in the CPUS
switch path.

Subject: [PATCH 2175/5214] perf tools: Bounds check perf_event_attr fields
 against attr.size before printing

perf_event_attr__fprintf() accessed all struct fields unconditionally,
but attrs from older perf.data files or BPF-captured syscall payloads
may have a smaller size than the current struct.  Fields beyond the
recorded size contain uninitialized or zero-filled data.

Add size-guarded macros (PRINT_ATTRn, PRINT_ATTRn_bf) that compare
each field's offset against attr->size before accessing it.

Guard the bitfield block (disabled, inherit, ... defer_output) with
attr_size >= 48.  These bitfields share a single __u64 at offset 40,
which is within PERF_ATTR_SIZE_VER0 for validated perf.data attrs,
but BPF-captured attrs from perf trace can have a smaller size when
the tracee passes a minimal struct to sys_perf_event_open.

Also fix the BPF trace path: when perf trace intercepts
sys_perf_event_open via BPF, the program copies PERF_ATTR_SIZE_VER0
bytes when the tracee passes size=0, but leaves the size field as 0.
Set attr->size to PERF_ATTR_SIZE_VER0 in the augmented syscall
handler so the bounds checks match the actual copied size.

Subject: [PATCH 2176/5214] perf header: Propagate feature section processing
 errors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

perf_session__read_header() discards the return value from
perf_header__process_sections(), so any error from a feature
section processor (process_nrcpus, process_compressed, etc.)
is silently ignored and the session opens as if nothing went
wrong.

This defeats the validation added by subsequent commits in this
series: a crafted perf.data that fails a feature section check
would still be processed with partially-initialized state.

Check the return value and fail the session if any feature
section processor returns an error.

For truncated files (data.size == 0, i.e. recording was
interrupted before the header was finalized), skip feature
section processing entirely and clear the feature bitmap so
tools use their "feature not present" fallbacks instead of
accessing uninitialized env fields.

Change the feature processor stubs for optional libraries
(libtraceevent, libbpf) from returning -1 to returning 0,
so that perf.data files containing these features can still be
opened on builds without the optional library — the feature is
simply skipped rather than causing a fatal error.

Also propagate evlist__prepare_tracepoint_events() failure as
-ENOMEM, since the function can fail due to strdup() allocation
failure inside evsel__prepare_tracepoint_event().

Fixes: 1c0b04d12ae9 ("perf tools: Add perf_session__read_header function")

Subject: [PATCH 2177/5214] perf header: Validate f_attr.ids section before use
 in perf_session__read_header()

perf_session__read_header() reads f_attr.ids.size from the perf.data
file and divides it by sizeof(u64) to compute nr_ids, which is
declared as int.  No validation is performed on the value before it
is used to allocate arrays and drive a read loop.

On 32-bit architectures, a crafted f_attr.ids.size of 0x100000000
(4 GB) produces nr_ids = 0x20000000, but the allocation size
1 * 0x20000000 * 8 overflows size_t to 0, so zalloc(0) returns a
valid pointer.  The subsequent loop writes 0x20000000 IDs into that
zero-length buffer, corrupting the heap.

On 64-bit, the u64-to-int truncation silently drops high bits,
processing fewer IDs than the file claims.  While not exploitable,
this is a data integrity issue.

Add validation before using f_attr.ids:

- Cap nr_attrs (attrs.size / attr_size) to MAX_NR_ATTRS (1 << 16)
  with overflow-safe u64 comparison before assigning to int
- Reject ids.size not aligned to sizeof(u64)
- Cap ids.size / sizeof(u64) to MAX_IDS_PER_ATTR (1 << 24) to
  prevent int truncation and size_t overflow on 32-bit
- Reject ids sections that extend past the end of the file,
  guarded by S_ISREG() so non-regular files (block devices,
  pipes) are not falsely rejected

Also fix perf_header__getbuffer64() to set errno = EIO when
readn() returns 0 (EOF).  Without this, the out_errno path in
perf_session__read_header() returns -errno which is 0 (success)
on truncated files, causing downstream NULL dereferences.

Subject: [PATCH 2178/5214] perf header: Validate feature section size and add
 read path bounds checking

Harden feature section parsing against crafted perf.data files:

1. perf_header__process_sections() reads the feature section table
   and passes each section's offset and size directly to the
   processing callbacks without validating them against the actual
   file size.  A crafted section size would make all downstream
   bounds checks against ff->size ineffective since they compare
   against the untrusted, inflated bound.  Add an fstat() check
   with S_ISREG() guard and verify that each section's offset +
   size does not extend past EOF.

2. __do_read_buf() validates reads against ff->size (section size),
   but __do_read_fd() had no such check, so a malformed perf.data
   with an understated section size could cause reads past the end
   of the current section into the next section's data.  Add the
   bounds check in __do_read(), the common caller of both helpers,
   so it is enforced uniformly for both the fd and buf paths.
   Track the section-relative offset in __do_read_fd() so the
   check works for the fd path.  Reject negative sizes which on
   32-bit can occur when a u32 >= 0x80000000 is passed as ssize_t.

3. do_read_string() relied on file data being null-padded.  Add
   explicit null-termination (buf[len-1] = '\0') after reading
   and validate length (>= 1, fits within section) before
   allocating, so callers like process_cpu_topology() never
   receive an unterminated string.

4. Initialize feat_fd.offset to 0 (section-relative) instead of
   section->offset (file-absolute) so the bounds tracking is
   consistent with __do_read()'s section-relative comparison.
   Adjust process_build_id() to use lseek() for its file-absolute
   offset needs since it cannot rely on ff->offset for that.

5. Propagate ff->size to perf_file_section__fprintf_info() so its
   reads are also bounded.

Subject: [PATCH 2179/5214] perf header: Sanity check HEADER_EVENT_DESC
 attr.size before swap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

read_event_desc() reads nre (event count), sz (attr size), and nr
(IDs per event) from the file and uses them to control allocations
and loops without validating them against the section size.

A crafted perf.data could trigger large allocations or many loop
iterations before __do_read() eventually rejects the reads.

Add bounds checks in read_event_desc():
- Reject sz smaller than PERF_ATTR_SIZE_VER0.
- Require at least one event (nre > 0).
- Check that nre events fit in the remaining section, using the
  minimum per-event footprint of sz + sizeof(u32).
- Pre-swap attr->size to native byte order, then reject values
  below PERF_ATTR_SIZE_VER0 or above sz before calling
  perf_event__attr_swap() to prevent heap out-of-bounds access.
- Handle ABI0 (attr.size == 0): substitute PERF_ATTR_SIZE_VER0,
  and on native-endian files write the value back so
  free_event_desc() does not treat the zero as its end-of-array
  sentinel (it iterates while attr.size != 0).  The swap path
  skips the write-back — perf_event__attr_swap() has its own
  ABI0 fallback that sets VER0 after swapping.
- Check that nr IDs fit in the remaining section before allocating.

Subject: [PATCH 2180/5214] perf header: Validate bitmap size before allocating
 in do_read_bitmap()

do_read_bitmap() reads a u64 bit count from the file and passes it
to bitmap_zalloc() without checking it against the remaining section
size. A crafted perf.data could trigger a large allocation that would
only fail later when the per-element reads exceed section bounds.

Additionally, bitmap_zalloc() takes an int parameter, so a crafted
size with bits set above bit 31 (e.g. 0x100000040) would pass the
section bounds check but truncate when passed to bitmap_zalloc(),
allocating a much smaller buffer than the subsequent read loop
expects.

Reject size values that exceed INT_MAX, and check that the data
needed (BITS_TO_U64(size) u64 values) fits in the remaining section
before allocating.  Switch from bitmap_zalloc() to calloc() of u64
units so the allocation size matches the u64 read/write granularity
and avoids unsigned long vs u64 mismatch on 32-bit architectures.

Fix do_write_bitmap() to use memcpy to read u64-sized chunks from
the unsigned long bitmap, preventing out-of-bounds reads on 32-bit
systems where sizeof(unsigned long) is 4 but the bitmap is stored
in u64 units.

Fix process_mem_topology() minimum section size: the check used
nr * 2 * sizeof(u64) per node, but do_read_bitmap() reads an
additional u64 for the bitmap size, so the minimum is 3 * sizeof(u64).

Fix memory leak in process_mem_topology() error paths: replace
free(nodes) with memory_node__delete_nodes() to free per-node
bitmaps allocated by do_read_bitmap().

Currently used by process_mem_topology() for HEADER_MEM_TOPOLOGY.

Subject: [PATCH 2181/5214] perf session: Add byte-swap handler for
 PERF_RECORD_COMPRESSED2

PERF_RECORD_COMPRESSED2 events carry a data_size field that must be
byte-swapped when reading cross-endian perf.data files.  Without a
swap handler, reading COMPRESSED2 events on a different-endian machine
would misinterpret data_size as a garbage value, causing the
decompression path to read the wrong number of bytes.

The compressed payload itself is a raw byte stream and needs no
swapping.

Subject: [PATCH 2182/5214] perf tools: Harden compressed event processing

Add several hardening checks to the compressed event decompression
pipeline:

1. Guard against decomp_last_rem underflow: check that
   decomp_last->head does not exceed decomp_last->size before
   subtracting.  A u64 underflow here would produce a huge
   decomp_len, causing an oversized mmap allocation.

2. Validate comp_mmap_len from the HEADER_COMPRESSED feature
   section: reject values that are not 4K-aligned or smaller than
   4096.  The downstream decompression path checks allocation
   sizes against SIZE_MAX, which handles 32-bit safety.

3. Validate COMPRESSED event header size: reject events where
   header.size is too small to contain the fixed struct fields,
   preventing underflow in the payload size calculation.

4. Validate COMPRESSED2 event data_size: check that data_size
   does not exceed the available payload (header.size minus the
   fixed struct fields) for the newer compressed format.

5. Reject compressed events when the HEADER_COMPRESSED feature
   is missing from the file header, which means no decompression
   context was initialized.

Subject: [PATCH 2183/5214] perf session: Check for decompression buffer size
 overflow

On 32-bit systems, sizeof(struct decomp) + decomp_len can wrap
size_t when comp_mmap_len is large.  The preceding patch validates
comp_mmap_len alignment but does not cap the upper bound, so two
additions can still overflow:

1. decomp_len += decomp_last_rem: on 32-bit, adding a u64 to
   size_t silently truncates, producing a corrupted decomp_len
   that would bypass the subsequent overflow check and result
   in an undersized buffer allocation.

2. sizeof(struct decomp) + decomp_len: the final addition could
   overflow on systems with small size_t.

Add explicit overflow checks before each addition as
defense-in-depth.

Subject: [PATCH 2184/5214] perf session: Bound nr_cpus_avail and validate
 sample CPU
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Several downstream consumers (timechart, kwork, sched) use fixed-size
arrays indexed by CPU.  A crafted perf.data can supply arbitrary CPU
values that index past these arrays, causing out-of-bounds access.

Validate sample.cpu against min(nr_cpus_avail, MAX_NR_CPUS) in
perf_session__deliver_event() before any tool callback runs.  The
cap at MAX_NR_CPUS protects fixed-size downstream arrays; the true
nr_cpus_avail is preserved in env for header parsing (e.g.
process_cpu_topology) which needs the real count.

Fall back to MAX_NR_CPUS when HEADER_NRCPUS is missing (truncated
files, pipe mode, pre-2017 perf).

Only validate when PERF_SAMPLE_CPU is set in sample_type — when
absent, evsel__parse_sample() leaves sample.cpu as (u32)-1, a
sentinel that downstream tools (script, inject) check to identify
events without CPU info.  Clamping it to 0 would break those checks.

Inline evlist__parse_sample() into perf_session__deliver_event()
so the evsel lookup needed for sample_type checking reuses the same
evsel that parsed the sample, avoiding a second evlist__event2evsel()
call on every event.

For pipe-mode streams where HEADER_NRCPUS may arrive late or not at
all, the MAX_NR_CPUS fallback ensures the bounds check is still
effective against the fixed-size downstream arrays.

Subject: [PATCH 2185/5214] perf kwork: Bounds check work->cpu before indexing
 cpus_runtime[]

work->cpu comes from sample->cpu which is (u32)-1 when
PERF_SAMPLE_CPU is absent.  Stored as int, this becomes -1
which passes the signed BUG_ON(work->cpu >= MAX_NR_CPUS) but
causes an out-of-bounds access on cpus_runtime[-1].

Replace the BUG_ON in top_calc_total_runtime() with an unsigned
bounds check that skips entries with invalid CPU values, counting
them for a summary warning.

Guard the same index in profile_event_match() (bitmap OOB),
top_calc_idle_time(), top_calc_irq_runtime(), top_calc_cpu_usage(),
and top_calc_load_runtime().  Also guard against division by zero
in top_calc_cpu_usage() when no runtime was accumulated.

Subject: [PATCH 2186/5214] perf session: Snapshot event->header.size in
 process_user_event()

On native-endian files, events are read from MAP_SHARED memory.
Multiple reads of event->header.size can return different values
if the file is concurrently modified, allowing an attacker to
bypass bounds checks performed on an earlier read.

Snapshot header.size into a local variable at function entry using
READ_ONCE() to prevent compiler rematerialization, and use it for
all size-dependent arithmetic within the function.  This ensures
every bounds calculation uses the same value that was validated
by the reader.

Subject: [PATCH 2187/5214] perf test: Add truncated perf.data robustness test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a shell test that verifies perf report handles truncated perf.data
files gracefully — exiting with an error code rather than crashing with
SIGSEGV or SIGABRT.

The test records a simple workload, then truncates the resulting
perf.data at four offsets that exercise different parsing stages:

  8 bytes   — file header magic only
  64 bytes  — partial file header (attr section incomplete)
  256 bytes — into the first events (partial event headers)
  75% size  — mid-stream truncation (partial event data)

For each truncation, perf report is run and the exit code is checked:

- Exit code 0 (success) fails the test — a truncated file should
  never parse without error.

- Crash signals are detected portably via kill -l, which maps the
  signal number to a name on the running system.  This handles
  architectures where signal numbers differ (e.g. SIGBUS is 7 on
  x86/ARM but 10 on MIPS/SPARC).  Core-dump and fatal signals
  (KILL, ILL, ABRT, BUS, FPE, SEGV, TRAP, SYS) fail the test.

- Higher exit codes (200+) are perf's own negative-errno returns
  (e.g. -EINVAL = 234) and are expected.

This exercises the bounds checking, minimum-size validation, and error
propagation added by the preceding patches in this series.

Testing it:

  root@number:~# perf test truncat
   84: Test that perf report handles truncated perf.data gracefully (no crash, no segfault — clean error exit).: Ok
  root@number:~# perf test -vv truncat
   84: Test that perf report handles truncated perf.data gracefully (no crash, no segfault — clean error exit).:
  --- start ---
  test child forked, pid 62890
  ---- end(0) ----
   84: Test that perf report handles truncated perf.data gracefully (no crash, no segfault — clean error exit).: Ok
  root@number:~#

Changes in v2:
- Add SIGKILL to the list of fatal signals so OOM kills from
  resource exhaustion bugs are detected (Reported-by: sashiko-bot@kernel.org)

Subject: [PATCH 2188/5214] perf test: Make leafloop workload immune to
 compiler options

Since the leafloop test program was moved into the main Perf binary as a
workload, it inherited the same compiler options as Perf. In this case
the -fstack-protector option broke the assumption that simple leaf
frames don't have a stack frame on Arm. This causes
test_arm_callgraph_fp.sh to pass even if the stack isn't augmented with
the link register, making the test useless.

Fix it by rewriting the leaf function in assembly seeing as it's so
simple. Adding -fno-stack-protector would also work, but wouldn't be
robust against other future compiler option additions.

The local variables and 'a' variable were never needed so remove them to
simplify.

Subject: [PATCH 2190/5214] remoteproc: xlnx: Enable auto boot feature

The remoteproc framework has capability to start (or attach to) the remote
processor automatically if auto boot flag is set by the driver during
probe. If the 'firmware-name' property is available for the remoteproc
node, then that firmware will be loaded and started during auto boot. If
the remote core is started by the bootloader then during auto-boot
remoteproc framework will try to attach to the remote processor.

The current architecture allocates and adds the remoteproc instance before
all the hardware such as sram, mbox, TCM is initialized. This design has
to be changed for auto boot to work. So, rename zynqmp_r5_rproc_add()
function to zynqmp_r5_rproc_alloc() and move adding the remoteproc
instance at the end of cluster initialization. This makes sure that all
the required hardware is initialized before starting the remote
processor.

Subject: [PATCH 2191/5214] tracing: Turn hist_elt_data field_var_str into a
 flexible array

The field_var_str array was allocated separately via kcalloc() with its
length already known at elt_data allocation time.  Convert it to a
flexible array member and fold the two allocations into a single
kzalloc_flex(), reordering hist_trigger_elt_data_alloc() so n_str is
computed and bounds-checked before the struct allocation.

hist_elt_data is only reached through tracing_map_elt::private_data
(a void *), never embedded, so adding a FAM imposes no tail-position
constraint on any enclosing struct.

Added __counted_by for extra runtime analysis.

Subject: [PATCH 2192/5214] tracing: Disable KCOV instrumentation for
 trace_irqsoff.o

When KCOV runs its boot selftest with whole-kernel instrumentation
enabled, it sets current->kcov_mode to KCOV_MODE_TRACE_PC without
installing a coverage area. Any instrumented code accepted as task-context
coverage in that window dereferences current->kcov_area and crashes.

On ARMv5 Versatile PB with CONFIG_KCOV_SELFTEST=y,
CONFIG_KCOV_INSTRUMENT_ALL=y and CONFIG_IRQSOFF_TRACER=y, boot hits a
NULL pointer fault during the selftest:

  kcov: running self test
  Internal error: Oops: 5 [#1] ARM
  PC is at __sanitizer_cov_trace_pc+0x4c/0x90
  Kernel panic - not syncing: Fatal exception

A diagnostic run showed the unwanted coverage comes from the IRQs-off
tracer callbacks reached from ARM IRQ entry before hardirq context is
visible to KCOV:

  __sanitizer_cov_trace_pc from tracer_hardirqs_off+0x18/0x1cc
  tracer_hardirqs_off from trace_hardirqs_off+0x34/0x54
  trace_hardirqs_off from __irq_svc+0x58/0xb0
  __irq_svc from kcov_init+0x7c/0xdc

and similarly through tracer_hardirqs_on().

trace_preemptirq.o is already excluded because this tracing path can run
from early interrupt code and produce coverage unrelated to syscall
inputs. Exclude trace_irqsoff.o as well, instead of requiring users to
turn off CONFIG_KCOV_INSTRUMENT_ALL=y, which is the default whole-kernel
KCOV mode.

With the exclusion in place, the same ARMv5 Versatile PB QEMU test boots
through the KCOV selftest and reaches userspace.

Tested on ARMv5 Versatile PB QEMU with CONFIG_KCOV_SELFTEST=y,
CONFIG_KCOV_INSTRUMENT_ALL=y and CONFIG_IRQSOFF_TRACER=y.

Subject: [PATCH 2193/5214] perf/ftrace: Fix WARNING in
 __unregister_ftrace_function

perf_ftrace_function_unregister() unconditionally calls
unregister_ftrace_function() without checking whether the ftrace_ops
was ever successfully registered. This triggers a WARN_ON in
__unregister_ftrace_function() when the ops doesn't have
FTRACE_OPS_FL_ENABLED set.

This can happen during perf_event_alloc() error cleanup when
perf_trace_destroy() is called via __free_event() on an event whose
ftrace_ops registration failed or was already torn down by
perf_try_init_event()'s err_destroy path.

The call path is:
  perf_event_alloc() error cleanup
    -> __free_event()
      -> event->destroy() [tp_perf_event_destroy]
        -> perf_trace_destroy()
          -> perf_trace_event_close()
            -> TRACE_REG_PERF_CLOSE
              -> perf_ftrace_function_unregister()
                -> unregister_ftrace_function()
                  -> __unregister_ftrace_function()
                    -> WARN_ON(!(ops->flags & FTRACE_OPS_FL_ENABLED))

Fix this by checking FTRACE_OPS_FL_ENABLED before attempting to
unregister. If the ops is not enabled, just free the filter and
return success.

Remove them for now, they can just be added back if they get
used in the future.

 compatible string for A9

Update dt-binding document for pinctrl of Amlogic A9.

In Amlogic A9 SoC, a bank mux register reuse other banks.
The multiplexed part requires special processing and is
therefore incompatible with the previous SoCs.

Subject: [PATCH 2201/5214] pinctrl: qcom: Replace open coded eoi call with
 irq_chip_eoi_parent()

Before commit 14dbe186b9d4 ("pinctrl: msmgpio: Make the irqchip immutable")
msm gpio irqchip conditionally initialized pctrl->irq_chip.irq_eoi to
irq_chip_eoi_parent() only for the GPIO irqs having a wakeup capable irq.

In order to make gpio irqchip immutable pctrl->irq_chip.irq_eoi is
initialized to msm_gpio_irq_eoi() which now gets invoked for both wake up
and non-wakeup capable GPIO IRQs.

Replace open coded eoi call to parent irqchip with irq_chip_eoi_parent().

Since the irq_chip_*_parent() APIs internally do not check the valid parent
data is present to ensure irq_chip_eoi_parent() is only invoked for wakeup
capable GPIOs validate d->parent_data within msm_gpio_irq_eoi().

For non wakeup capable GPIOs d->parent_data will be NULL since parent
irqchip diconnects hierarchy using irq_domain_disconnect_hierarchy() and
later irq framework trims hierarchy using irq_domain_trim_hierarchy() which
makes d->parent_data as NULL.

No functional impact.

 platform_device_id arrays
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Named initializers are better readable and more robust to changes of the
struct definition. This robustness is relevant for a planned change to
struct platform_device_id replacing .driver_data by an anonymous unit.

While touching these arrays unify spacing and usage of commas.

Subject: [PATCH 2203/5214] pinctrl: max77620: Unify usage of space and comma
 in platform_device_id array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The most accepted style for the array terminator is to use a single
space between the curly braces and no trailing comma. Also don't use a comma
directly before a closing brace in the other entries.

Subject: [PATCH 2204/5214] KVM: x86: ioapic: Use old_dest_mode consistently in
 ioapic_write_indirect()

When reconstructing a temporary IRQ state from the historical/old IOAPIC
redirection table configuration in ioapic_write_indirect(), the code
previously assigned 'irq.dest_id' from 'old_dest_id', but incorrectly
queried the live/new 'e->fields.dest_mode' to populate 'irq.dest_mode'.

Mixing the old destination ID with the new destination mode creates an
inconsistent, hybrid IRQ state. This discrepancy leads to an incorrect
vCPU bitmap calculation via kvm_bitmap_or_dest_vcpus(), causing subsequent
interrupt routing updates (such as RTC interrupt handling) to target the
wrong set of virtual processors if both fields were modified simultaneously.

Fix this by using 'old_dest_mode' consistently alongside 'old_dest_id' to
ensure the historical IRQ structure is reconstructed accurately.

Subject: [PATCH 2215/5214] perf jevents: Add IOMMU metrics for AMD

Add IOMMU Translation Lookaside Buffer (TLB) and interrupt cache metrics
to perf jevents for AMD platforms. This enhances I/O performance
observability, allowing fleet-wide monitoring of IOMMU overhead.

These metrics are supported on Zen 2 and newer processors (Rome, Milan,
Genoa, Turin) and are implemented using the standard `amd_iommu` PMU
events. The implementation uses the existing `_zen_model` helper to
ensure these are only generated for Zen 2+. Note that the pde events on
AMD cover both 2M and 1G pages, so 1G pages are implicitly included in
the total hits/misses metrics (sum of pte and pde events).

The following metrics are added:
- iotlb_total_hit: Total IOTLB hits (4K, 2M, 1G pages).
- iotlb_total_miss: Total IOTLB misses.
- iotlb_miss_rate: IOTLB miss rate.
- iotlb_interrupt_cache_hit: Interrupt cache hits.
- iotlb_interrupt_cache_miss: Interrupt cache misses.
- iotlb_interrupt_cache_lookup: Interrupt cache lookups.
- iotlb_interrupt_cache_miss_rate: Interrupt cache miss rate.

Tested:
  # perf stat -M \
    iotlb_total_hit,iotlb_total_miss,iotlb_miss_rate \
    --per-socket --metric-only -a -j -- sleep 10
  {"socket" : "S0", "counters" : 10,
   "hits  iotlb_total_hit" : "3579249.0",
   "%  iotlb_miss_rate" : "0.0",
   "misses  iotlb_total_miss" : "3.0"}
  {"socket" : "S1", "counters" : 10,
   "hits  iotlb_total_hit" : "0.0",
   "%  iotlb_miss_rate" : "0.0",
   "misses  iotlb_total_miss" : "0.0"}

Subject: [PATCH 2216/5214] perf jevents: Add IOMMU metrics for Intel

Add IOMMU Translation Lookaside Buffer (TLB) and interrupt cache metrics
to perf jevents for Intel platforms. This enhances I/O performance
observability, allowing fleet-wide monitoring of IOMMU overhead.

These metrics are supported on platforms that expose the required uncore
IIO IOMMU events (such as Emerald Rapids and Granite Rapids).

The Intel implementation dynamically detects event availability at
generation time.

It requires at least the TLB events to expose the metric group, while
the interrupt cache events are optional. This allows platforms like
Emerald Rapids, which lack IOMMU interrupt cache events, to still expose
the IOMMU TLB metrics.

The following metrics are added:

- iotlb_total_hit: Total IOTLB hits (4K, 2M, 1G pages).
- iotlb_total_miss: Total IOTLB misses.
- iotlb_miss_rate: IOTLB miss rate.
- iotlb_interrupt_cache_hit: Interrupt cache hits.
- iotlb_interrupt_cache_miss: Interrupt cache misses (calculated as
  lookup - hit, clamped to zero).
- iotlb_interrupt_cache_lookup: Interrupt cache lookups.
- iotlb_interrupt_cache_miss_rate: Interrupt cache miss rate.

Tested:
  # perf stat -M \
    iotlb_total_hit,iotlb_total_miss,iotlb_miss_rate \
    --per-socket --metric-only -a -j -- sleep 10
  {"socket" : "S0", "counters" : 10,
   "hits  iotlb_total_hit" : "3579249.0",
   "%  iotlb_miss_rate" : "0.0",
   "misses  iotlb_total_miss" : "3.0"}
  {"socket" : "S1", "counters" : 10,
   "hits  iotlb_total_hit" : "0.0",
   "%  iotlb_miss_rate" : "0.0",
   "misses  iotlb_total_miss" : "0.0"}

Subject: [PATCH 2217/5214] perf util: Fix perf_exe() buffer write past end
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

perf_exe() passes len to readlink() and then unconditionally writes a
trailing NUL at buf[n]. If readlink() returns len, the write lands one
byte past the buffer.

Read at most len - 1 bytes and keep the existing NUL termination. Also
guard the fallback path for tiny buffers so copying "perf" cannot
overflow.

Subject: [PATCH 2218/5214] perf arm-spe: Don't warn about the discard bit if
 it doesn't exist

Opening an SPE event shows a warning that doesn't concern the user:

  $ perf record -e arm_spe
  Unknown/empty format name: discard

Perf only wants to know if the discard bit is set for configuring the
event, not in response to anything the user has done. Fix it by adding
another helper that returns if a config bit exists without warning.

We should probably keep the warning in evsel__get_config_val() to avoid
having every caller having to do it, and most format bits should never
be missing.

Add a test for the new helper. Rename the parent test function to be
more generic rather than adding a new one as it requires a lot of
boilerplate.

Subject: [PATCH 2220/5214] perf annotate: Fix missing branch counter column in
 TUI mode

'perf annotate' checks that evlist->nr_br_cntr has been incremented to
determine whether to show branch counter information.

However, this data is not populated until after the check when events
are processed.

Therefore, this counter will always be less than zero and the Branch
Count column is never shown. Do this check after events have been
processed and branch counter data is updated.

Subject: [PATCH 2221/5214] dt-bindings: Input: Add Wacom W9000-series penabled
 touchscreens

Add bindings for Wacom W9002 and two Wacom W9007 variants which can be
found in tablets.

W9002, W9007A LT03, and W9007A V1 differ in the length of the return
message containing coordinates, distance, pressure and button status.

Subject: [PATCH 2223/5214] Revert "media: venus: hfi_platform: Correct
 supported codecs for sc7280"

This reverts commit c0ab2901fc68 ("media: venus: hfi_platform: Correct
supported codecs for sc7280"). The codecs might be deprecated, but they
still work (somewhat) perfectly and don't cause any issues with the rest
of the system. Reenable VP8 codecs by reverting the offending commit.

Tested with fluster:

|Test|FFmpeg-VP8-v4l2m2m|GStreamer-VP8-V4L2|
|TOTAL|50/61|50/61|
|TOTAL TIME|12.171s|11.824s|

Subject: [PATCH 2226/5214] media: qcom: venus: drop extra padding in NV12 raw
 size calculation

get_framesize_raw_nv12() currently adds SZ_4K to the UV plane size and an
additional SZ_8K to the total buffer size. This inflates the calculated
sizeimage and leads userspace to over-allocate buffers without a clear
requirement.

Remove the extra SZ_4K/SZ_8K padding and compute the NV12 size as the sum
of Y and UV planes, keeping the final ALIGN(size, SZ_4K) intact.

 dimension steps on v4

Encoder HFI capabilities on v4 advertise a 16-pixel step for frame and
blur dimensions. This is overly restrictive and can cause userspace caps
negotiation to fail even for valid resolutions.

Relax the advertised step size to 1 and keep alignment enforcement in
buffer layout and size calculations.

Subject: [PATCH 2229/5214] media: qcom: venus: add power domain enable logic
 for Venus cores

Attach power domains for vdec and venc cores and power them up if a vdec
or venc session is started.

Vcodec clocks are added and enabled to the core Venus device both for
vcodec0 and vcodec1. To ensure they are added only once, introduce a new
property "vcodec_clks", which is an array of clocks which are enabled
both during decode and encode and is retrieved from the device tree only
once.

Requesting the IRQ and then immediately disabling it is fragile as it
leaves a window when the IRQ is still enabled although the underlying
device might be not completely setup for IRQ handling. Pass
IRQF_NO_AUTOEN instead of calling disable_irq_nosync().

Subject: [PATCH 2233/5214] media: dt-bindings: qcom,sm8550-iris: Add X1P42100
 compatible

Document the new compatible string "qcom,x1p42100-iris".

Unlike SM8550 where the BSE (Bitstream Engine) is clocked implicitly
via vcodec0_core, x1p42100 exposes a dedicated BSE clock vcodec0_bse
that requires explicit enable/disable and frequency configuration.
The SM8550 driver has no knowledge of this clock and therefore cannot
operate x1p42100 hardware correctly.

Subject: [PATCH 2238/5214] media: qcom: iris: Add hierarchical coding support
 for encoder

Add hierarchical coding support for both gen1 and gen2 encoders by enabling
 the following V4L2 controls:
H264:
V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING,
V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING_TYPE,
V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING_LAYER
HEVC(gen2 only):
V4L2_CID_MPEG_VIDEO_HEVC_HIER_CODING_TYPE,
V4L2_CID_MPEG_VIDEO_HEVC_HIER_CODING_LAYER

Subject: [PATCH 2239/5214] media: qcom: iris: Optimize
 iris_hfi_gen1_packet_session_set_property

Modify iris_hfi_gen1_packet_session_set_property to simplify size
calculations and remove redundant code patterns.

Previously, packet->shdr.hdr.size was incremented by sizeof(u32) in
every switch case, resulting in repetitive and less maintainable
logic.

Subject: [PATCH 2241/5214] media: iris: add FPS calculation and VPP FW
 overhead in frequency formula
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver was using a fixed default FPS value when calculating the VPU
frequency. This caused wrong frequency requests for high‑frame‑rate
streams, for example 4K at 240 FPS. Because of this, the hardware was
running at a lower frequency than needed.

Add the FPS measurement based on the decoder input buffer arrival rate.
The measured FPS is stored per instance and used in frequency calculation
instead of the fixed default FPS. The value is clamped so that it does
not exceed platform limits. Add a VPP firmware overhead when running in
STAGE_2.

Subject: [PATCH 2242/5214] media: iris: optimize COMV buffer allocation for
 VPU3x and VPU4x

The existing iris_vpu_dec_comv_size() used VIDEO_MAX_FRAME (32) as
num_comv count unconditionally when calculating the co-located motion
vector (COMV) buffer size. This resulted in an oversized COMV buffer
allocation throughout decode session, wasting memory regardless of
actual number of buffers required.

For VPU3x and VPU4x platforms, introduce iris_vpu3x_4x_dec_comv_size() to
replace iris_vpu_dec_comv_size(). These derive num_comv dynamically, it
uses inst->fw_min_count once the firmware has reported its buffer
requirements, and fallback to output count during initialization before
firmware has communicated its requirements. This aligns the COMV buffer
size to the actual count needed rather than always allocating with fixed
VIDEO_MAX_FRAME value.

Additionally, during iris_vdec_inst_init(), fw_min_count was initialized
to MIN_BUFFERS instead of 0. This masked the fallback logic and caused the
COMV size calculation to use MIN_BUFFERS even before firmware had reported
its actual requirements. Fix this by initializing fw_min_count to 0.

During testing of 1080p AVC, it reduces the COMV buffer size from 32.89MB
to 6.16MB per decode session, significantly reducing memory consumption.

Subject: [PATCH 2243/5214] media: iris: Add hardware power on/off ops for
 X1P42100

On X1P42100 the Iris block has an extra BSE clock. Wire this clock into
the power on/off sequence.

The BSE clock is used to drive the Bin Stream Engine, which is a sub-block
of the video codec hardware responsible for bitstream-level processing. It
is required to be enabled separately from the core clock to ensure proper
codec operation.

Subject: [PATCH 2246/5214] media: iris: Initialize HFI ops after firmware load
 in core init

The HFI sys ops were previously initialized in probe() but, we don't
have firmware loaded at probe time. Since HFI is tightly coupled to
firmware, initialize the HFI sys ops after firmware has been successfully
loaded and booted.

Subject: [PATCH 2248/5214] clk: samsung: exynos990: Fix PERIC0/1 USI clock
 types

Use nMUX() for USI and UART user muxes to allow reparenting between
OSC and CMU IP output when changing rates, and use DIV_F() with
CLK_SET_RATE_PARENT on their dividers and gates so rate requests
propagate upward.

Consolidate identical USI parent arrays into shared
mout_peric0_nonbususer_p and mout_peric1_nonbususer_p.

Subject: [PATCH 2249/5214] KVM: VMX: Macrofy GPR swapping in __vmx_vcpu_run()

Convert the repeated register save/restore sequences into macros,
trading some level of implementation trickiness for conciseness (more
than one register can be saved/restored with one invocation) and a
smaller chance of cut and paste errors.

This is particularly useful in preparation for extended GPR support;
upcoming support for APX would need to add 32 lines to the VM entry/exit
paths.

No functional change intended.

Subject: [PATCH 2250/5214] KVM: SVM: Macrofy GPR swapping in __svm_vcpu_run()

Convert the register save/restore sequences in the SVM entry into macros,
following the VMX code. Drop the now-redundant register offset defines.

No functional change intended.

Subject: [PATCH 2252/5214] Input: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

The driver doesn't make use of the value that was explicitly assigned to
the .driver_data members. Drop the assignment. While touching the array,
convert it to use named initialization which is easier to understand.

The former RDI-specific register definitions (CSID_RDI_CFG0/CTRL) are
renamed to unified CSID_CFG0/CSID_CTRL variants, as their layout is
interface agnostic. This refactoring provides the foundation for
extending csid-340 with missing PIX interface/path support.

Subject: [PATCH 2255/5214] media: qcom: camss: csid-340: Add port-to-interface
 mapping

The CSID-340 block uses different register offsets for the PIX and RDI
interfaces, but the driver previously indexed these registers directly
with the camss port number. This happened to work for RDI because the
port index matches the RDI register layout, but this assumption breaks
with upcoming PIX interface support

Introduce an explicit port-to-interface mapping and use the mapped iface
index when programming CSID_CFG0 and CSID_CTRL. This replaces the
standalone __csid_ctrl_rdi() helper and simplifies the RDI stream setup
path.

Also correct the CSID_CFG0/CTRL base offsets and clean up the code in
preparation for full PIX path support.

Like RDI, PIX outputs Bayer frames but can also achieve some image
processing such as scaling, cropping and generating statitics (e.g.
histogram), it also offer more flexebility in term of image alignment
and stride. All of that can then later be leveraged to improve
software or hardware frames post-processing.

Subject: [PATCH 2256/5214] media: qcom: camss: csid-340: Enable PIX interface
 routing

Add PIX path support to the CSID-340 driver. The hardware exposes a
dedicated PIX interface in addition to the existing RDI paths, but
the driver only supported RDI stream configuration so far.

The PIX path is configured similarly to RDI but requires decode-format
to be specified.

The PIX pipeline can subsequently perform further processing,
including scaling, cropping, and statistics.

Subject: [PATCH 2257/5214] media: qcom: camss: vfe-340: Proper client handling

We need to properly map camss WM index to our internal WM client
instance. Today we only support RDI interfaces with the RDI_WM
macro, introduce a __wm_to_client helper to support any interface.

Subject: [PATCH 2258/5214] dt-bindings: iio: gyroscope: add mount-matrix for
 bmg160

The mount-matrix property supplies a 3x3 matrix that is used
to transform the values from the gyroscope to get vector
values that are relative to the way the sensor has been mounted
on the device. When the property is not specified, the identity
matrix is used.

This change adds mount-matrix as an optional property to the
dt-bindings for the bmg160 gyroscope.

Subject: [PATCH 2259/5214] iio: backend: add devm_iio_backend_get_by_index()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a new function to get an IIO backend by its index in the
io-backends device tree property. This is useful for multi-channel
devices that have multiple backends, where looking up by index is
more straightforward than using named backends.

Extract __devm_iio_backend_fwnode_get_by_index() from the existing
__devm_iio_backend_fwnode_get(), taking the index directly as a
parameter. The new public API devm_iio_backend_get_by_index() uses
the index to find the backend reference in the io-backends property,
avoiding the need for io-backend-names.

Add support for the AD4880, a dual-channel 20-bit 40MSPS SAR ADC
with integrated fully differential amplifiers (FDA).

The AD4880 has two independent ADC channels, each with its own SPI
configuration interface. This requires:
- Two entries in reg property for primary and secondary channel
  chip selects
- Two io-backends entries for the two data channels

Subject: [PATCH 2261/5214] iio: adc: ad4080: add support for AD4880
 dual-channel ADC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for the AD4880, a dual-channel 20-bit 40MSPS SAR ADC with
integrated fully differential amplifiers (FDA).

The AD4880 has two independent ADC channels, each with its own SPI
configuration interface. The driver uses spi_new_ancillary_device() to
create an additional SPI device for the second channel, allowing both
channels to share the same SPI bus with different chip selects.

Subject: [PATCH 2263/5214] iio: adc: ad7625: fix type mismatch in clamp()
 macro

clamp() expects compatible operand types. The period calculation uses
nanosecond constants, while the local target variable was narrower than
the upper bound expression.

Make target unsigned long and use unsigned long bounds, including
NSEC_PER_USEC for the upper limit. This keeps the operands naturally
aligned without adding casts.

Subject: [PATCH 2267/5214] iio: buffer: Move from int64_t to s64 for timestamp

iio_push_to_buffers_with_ts_unaligned() uses int64_t for timestamp.
Move it from int64_t to s64 to make consistent with:
- iio_push_to_buffers_with_ts()
- all current users that supply s64 anyway

This will reduce potential of wrong type being chosen when using
this API.

Refactor the ad9832_calc_freqreg by removing the redundant u64 casts
and 1L bitwise left shift and replacing the multiplication by a bit
shift, as multiplying integers by a power of two is identical to a
bitwise left shift.

 function

Replace open-coded dev_err() + return sequences with dev_err_probe(),
which is the preferred pattern for probe error paths as it handles
deferred probing correctly and reduces boilerplate.

Convert all three remaining instances in ad9834_probe():
 - master clock enable failure
 - device init SPI sync failure

The avdd regulator path already used dev_err_probe().

Subject: [PATCH 2275/5214] iio: light: stk3310: Deal with the ps interrupt
 issue in PM

On the Inspur HS326 laptop(which integrated with HiSilicon M900
processor), if the STK3311-X chip's PS interrupt is configured
in "Recommended interrupt mode", the interrupt cannot be triggered
normally after waking from suspend or hibernation.

In this case, neither disabling and re-enabling the interrupt nor
resetting the PS threshold register can restore the interrupt to
normal operation.

If the interrupt is disabled in suspend() then reset the PS threshold
register and enable the interrupt in resume(). This resolves the issue.

Subject: [PATCH 2278/5214] iio: Move MODULE_DEVICE_TABLE next to the table
 itself

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it
exports, because this is easier to read and verify.  It also makes more
sense since #ifdef for ACPI or OF could hide both of them.

Most of the drivers already have this correctly placed, so adjust
the missing ones.  No functional impact.

Subject: [PATCH 2280/5214] iio: light: si1133: reset counter to prevent race
 condition

Sashiko reported a potential race condition happening when the driver
returns an errno after a timeout in the si1133_command() function. The
premature exit causes the hardware and software counters to become out
of sync by not updating data->rsp_seq, therefore the internal hardware
counter keeps incrementing.

Fix this by adding a call to si1133_cmd_reset_counter() before returning
from timeout.

Subject: [PATCH 2281/5214] iio: light: si1133: prevent race condition on
 timeout

Sashiko reported a bug where the si1133_command exits on timeout
without halting the sensor or masking the interrupt. If the sensor
completes the command later, any subsequent command to the sensor
will cause the IRQ handler to complete immediately, returning stale
data to the driver all while the command hasn't finished yet, shifting
all potential reads in the future.

Fix this by masking the IRQ if wait_for_completion_timeout() fails.
When initiating a new command, do a dummy read of the IRQ_STATUS
register and turn the IRQ back on.

Subject: [PATCH 2288/5214] iio: magnetometer: rm3100: Modernize locking and
 refactor control flow

Replace mutex_lock() and mutex_unlock() calls in rm3100-core.c with
the more modern guard(mutex)() family. This will help modernize the
driver and bring it up-to-date with modern available macros/functions.

While replacing mutex_lock() and mutex_unlock(), the critical sections
of rm3100_read_mag() and rm3100_get_samp_freq() have been extended to
include negligible operations for cleaner logic.

Add new helper-wrapper function rm3100_regmap_bulk_read_locked() to
help keep rm3100_trigger_handler() switch-cases clean while maintaining
mutex locking and avoiding re-entrancy risks from potential callbacks.

While at it, remove redundant gotos where applicable, and use direct
returns instead. In addition, remove regmap variable in
rm3100_trigger_handler() as its references have been replaced with
variable data.

Subject: [PATCH 2289/5214] iio: adc: mcp3422: rewrite mask macros with help of
 bits.h APIs

Rewrite MCP3422_CHANNEL_MASK, MCP3422_SRATE_MASK, MCP3422_PGA_MASK
and MCP3422_CONT_SAMPLING using GENMASK() and BIT() macros from
bits.h.

The other macros MCP3422_SRATE_{240, 60, 15, 3} were not changed
because they are also used as array indices.

Subject: [PATCH 2301/5214] iio: magnetometer: ak8975: pass conversion timeouts
 as arguments

Refactor wait_conversion_complete*_() helper function to accept poll
and timeout values directly as parameters. This improves the
readability of the code and does not rely on hardcoded macros.

Besides that, fix the home grown and obviously wrong in some cases the
jiffy-based timeout.

Avoid using temporary variable in ak8975_read_axis(). With that being done,
the clamp_t() call becomes idiomatic in the driver and can be factored out

Subject: [PATCH 2308/5214] iio: adc: ingenic-adc: refactor
 ingenic_adc_read_chan_info_raw()

Extract the sample logic from ingenic_adc_read_chan_info_raw() into
a new helper function __ingenic_adc_read_chan() to improve code
readability and modularity.

The helper handles the mutex-protected section for sampling channels,
while the main function manages mutex and clock enabling/disabling.

Subject: [PATCH 2309/5214] iio: adc: ingenic-adc: use guard()() and
 scoped_guard() to handle synchronisation

Replace mutex_lock() and mutex_unlock() calls with guard()() in
functions ingenic_adc_set_adcmd(), ingenic_adc_set_config(),
ingenic_adc_enable(), ingenic_adc_capture(), and with scoped_guard()
in function ingenic_adc_read_chan_info_raw().

This removes the need to call the unlock function, as the lock is
automatically released when the function return or the scope exits
for any other case.

Subject: [PATCH 2315/5214] iio: chemical: scd30: reject (response=NULL,
 size>0) in scd30_i2c_command()

scd30_i2c_command() takes an opaque "response" buffer plus its size.
At the start of the function the code already checks if response is
NULL (via the rsp local), but the response-decoding loop after the
i2c transfer always dereferences rsp without re-checking. With the
current callers in scd30_core.c this is harmless, since write
commands pass response=NULL together with size=0 (so the loop body
is never entered).

The (response=NULL, size>0) combination has no useful meaning: there
is nowhere to put the bytes that come back from the chip. Treat it
as an invalid argument and bail out at the top of the function with
-EINVAL, instead of silently doing the i2c transfer and dereferencing
a NULL pointer in the decode loop.

smatch flagged the inconsistency:

  drivers/iio/chemical/scd30_i2c.c:104 scd30_i2c_command() error: we
    previously assumed rsp could be null (see line 77)

No functional change for the existing callers, which only ever use
(response=NULL, size=0) for writes and (response!=NULL, size>0) for
reads.

Subject: [PATCH 2316/5214] iio: adc: ad7793: replace usleep_range() with
 fsleep()

The AD7792/AD7793 datasheet (Rev. B, page 25, RESET section)
says: "When a reset is initiated, the user must allow a period
of 500 us before accessing any of the on-chip registers."

Use fsleep(500) instead of usleep_range(500, 2000). The 500 us
minimum stays the same; fsleep() picks the upper slack itself
(about +25% on a default config -- narrower than the original
2000 us).

Add a code comment with the datasheet reference so the "why"
of the wait is visible at the call site.

Subject: [PATCH 2317/5214] iio: frequency: adrf6780: replace usleep_range()
 with fsleep()

The ADRF6780 datasheet (Rev. D, page 23, ADC section) says:
"Wait approximately 200 us for the ADC to be ready."

fsleep(200) expands to the same usleep_range(200, 250). Use the
flexible sleep helper, which picks the right primitive for the
given microsecond delay.

Replace the generic "Recommended delay for the ADC to be ready"
comment with the datasheet reference so the "why" of the wait is
visible at the call site.

No functional change.

Subject: [PATCH 2318/5214] iio: adc: ti-ads1298: Fix incorrect timeout comment

At the lowest supported data rate of 250Hz, one conversion period is
4ms, not 40ms. The 50ms timeout is deliberately conservative to allow
for kernel scheduling latency, which can be significant under load or
on slow machines.

Fix the comment to state the correct conversion time, use "lowest sample
rate" for clarity, and explain that the extra margin exists to absorb
scheduling latency so that no one is tempted to shrink the timeout to
match the conversion period.

Also drop the redundant ret variable assignment by using the return value
of wait_for_completion_timeout() directly in the if() condition.

Subject: [PATCH 2320/5214] iio: adc: ti-ads1298: Remove unnecessary CONFIG2
 write during init

The driver was enabling the internal test signal (INT_TEST), double
amplitude (TEST_AMP), and fast frequency (TEST_FREQ_FAST) bits in
CONFIG2 during initialization. These bits activate an internal square
wave generator intended for device testing and calibration, not normal
ECG operation.

CONFIG2 defaults to having only the RESERVED bit set after reset, which
is the correct value for normal operation. Remove the write entirely
since it would just be writing the reset default value.

Implement the .read_label callback to allow userspace to identify ADC

The change has been tested on Sony Xperia SP (PM8921).

Subject: [PATCH 2326/5214] dt-bindings: iio: adc: hx711: clean up existing
 binding text

Rewrite the binding description and property text so it describes the
existing HX711 hardware behavior directly instead of documenting old
driver implementation details.

Also clarify that clock-frequency controls the SCK bit-bang timing.

No functional change.

Subject: [PATCH 2327/5214] iio: adc: hx711: move scale computation to
 per-device storage

The gain-to-scale table is global today, so probe-time scale updates for
one device overwrite the values used by any earlier device instance.

Fix this by making the gain table const and storing the computed scale
values per device in hx711_data.

No functional change for single-sensor configurations.

For the four drivers the .driver_data member of i2c_device_id is
write-only. Drop the explicit assignment.

While touching these arrays use a named initializer to assign the .name
member, which is easier to parse for a human.

 with iopoll() macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver currently uses while loops and msleep() for polling during
conversion waits.

Replace the custom polling loops with readx_poll_timeout() and
read_poll_timeout() macros from <linux/iopoll.h>. This reduces
boilerplate, standardizes timeout handling and improves overall code
readability, keeping the original timing and error behaviour. Add
<linux/time.h> for USEC_PER_MSEC macro instead of using magic numbers.

Subject: [PATCH 2334/5214] staging: iio: addac: adt7316: document SPI
 interface switching sequence

The device powers up in I2C mode. Switching to SPI mode
requires sending a sequence of SPI writes as described in
the datasheet.

During this sequence, the device may still be in I2C mode,
so SPI transactions may not be recognized and can fail.
Such errors are therefore ignored.

Add a comment to clarify this behavior.

Subject: [PATCH 2335/5214] iio: magnetometer: ak8975: ensure device is awake
 for buffered capture

Currently, the ak8975_start_read_axis() can be called while the device
is autosuspended, causing two issues:

1. I2C transfers in the aforementioned function will fail or timeout
because ak8975_runtime_suspend() disables the device regulators.
2. Since ak8975_fill_buffer() does not hold runtime references,
ak8975_runtime_suspend() can run concurrently, and since PM callbacks
do not use a locking mechanism, it may cause a race accessing the
control register via the I2C bus.

Fix this issue by adding struct iio_buffer_setup_ops that contains
preenable and postdisable functions to ensure correct that device is
powered on when running a buffered capture.

Subject: [PATCH 2336/5214] iio: magnetometer: ak8975: fix potential kernel
 stack memory leak

Currently in the AK8975 driver there are four instances where potential
uninitialized kernel stack memory leaks can occur. If
i2c_smbus_read_i2c_block_data_or_emulated() returns a value less than
the size of the buffer, uninitialized bytes are retained in the buffer
and later the buffer is passed on to IIO buffers, potentially leaking
memory to userspace.

Fix this by adding checks whether the return value of the function is
equal to the size of the buffer and subsequently if the value is
lesser than zero to distinguish from a returned error code.

Subject: [PATCH 2339/5214] iio: adc: ad7192: fix GPOCON register access
 annotation

The comment next to AD7192_REG_GPOCON marks the register as RO,
but the AD7192 datasheet (Rev. A, page 24, GPOCON REGISTER) says:
"The GPOCON register is an 8-bit register from which data can be
read or to which data can be written."

The driver itself uses ad_sd_write_reg() against this register in
ad7192_show_scale() / write paths to control the bridge power-down
switch and digital outputs, which matches the RW datasheet
description. Update the comment to RW so it does not mislead
future readers.

Subject: [PATCH 2340/5214] Documentation: iio: fix typo in triggered-buffers
 example

In the "IIO triggered buffer setup" example, iio_triggered_buffer_setup()
is called with "sensor_iio_polfunc" (single 'l') while the function is
defined and later referenced as "sensor_iio_pollfunc" (double 'l'). Fix
the misspelling so the example is consistent.

Subject: [PATCH 2341/5214] Documentation: iio: make ADXL Y-axis calibbias
 description consistent

The Y-axis calibbias rows in adxl345.rst, adxl313.rst and adxl380.rst
use a different wording than the matching X-axis and Z-axis rows in
the same tables: the X/Z rows say "Calibration offset for the
X/Z-axis accelerometer channel." while the Y row says "Y-axis (or
y-axis) acceleration offset correction".

Make the Y-axis row match the other two so each driver's sysfs
table has consistent capitalisation and wording.

Add a Devicetree binding for the MEMSIC MMC5983MA 3-axis
magnetometer.

MMC5983MA is not register-compatible with the existing MEMSIC
magnetometer drivers. It has a different register map, 18-bit output
data format, and I2C/SPI transport support.

Subject: [PATCH 2344/5214] iio: light: opt3001: make headers conform to iwyu

Remove kernel.h proxy header, device.h, irq.h, slab.h as they are
unnecessary and add missing headers (array_size.h, dev_printk.h,
errno.h, jiffies.h, wait.h) to enforce IWYU principle and reduce
transitive dependencies. Also, replace bitops.h with bits.h as only
the BIT() macro is used.

Subject: [PATCH 2346/5214] iio: adc: xilinx-ams: fix out-of-bounds channel
 lookup in event handling

ams_event_to_channel() may return a pointer past the end of
dev->channels when no matching scan_index is found. This can lead
to invalid memory access in ams_handle_event().

Add a bounds check in ams_event_to_channel() and return NULL when
no channel is found. Also guard the caller to safely handle this
case.

Subject: [PATCH 2347/5214] iio: adc: xilinx-ams: use guard(mutex) for
 automatic locking

Replace open-coded mutex_lock()/mutex_unlock() pairs with
guard(mutex) to simplify locking and ensure proper unlock on
all control flow paths.

This removes explicit unlock handling, reduces boilerplate,
and avoids potential mistakes in error paths while keeping
the behavior unchanged.

Subject: [PATCH 2348/5214] iio: adc: xilinx-ams: refactor alarm mapping to
 table-driven approach

Replace multiple open-coded switch statements that map between
scan_index, alarm bits, and register offsets with a centralized
table-driven approach.

Introduce a struct-based alarm_map to describe the relationship
between scan indices and alarm offsets, and add a helper to
translate scan_index to event IDs. This removes duplicated logic
across ams_get_alarm_offset(), ams_event_to_channel(), and
ams_get_alarm_mask().

The new approach improves maintainability, reduces code size,
and makes it easier to extend or modify alarm mappings in the
future, while preserving existing behavior.

        eg. <&gpadc 1> will fail if there is only channel@1 specified

Add .fwnode_xlate() which maps DT phandle to the registered channel
whose chan->channel matches the hardware channel number. It allows
sparse channel maps to be consumed by drivers like iio-hwmon.

Tested on Radxa Cubie A5E.

 scan buffer

Use BME680_NUM_CHANNELS instead of the hardcoded channel count
in the scan buffer.

This avoids use of a magic number and improves code readability
and maintainability.

Subject: [PATCH 2356/5214] iio: accel: mma8452: handle I2C read error(s) in
 mma8452_read()

Currently, If i2c_smbus_read_i2c_block_data() fails but
mma8452_set_runtime_pm_state() succeeds, mma8452_read() returns 0.

As a result, the caller mma8452_read_raw() assumes the read was
successful and proceeds to use a buffer containing uninitialized
stack memory.

Add proper checking of the I2C read return value and propagate errors
to the caller.

Subject: [PATCH 2357/5214] iio: accel: mma8452: switch to non-devm
 request_threaded_irq()

Avoid using devm_request_threaded_irq() as the driver requires explicit
error-handling path(s). Using devm_* API together with goto-based
unwinding breaks the expected LIFO resource release model.

Add explicit IRQ cleanup in the driver teardown paths to follow kernel
resource management conventions.

Subject: [PATCH 2361/5214] iio: trigger: drop generic interrupt trigger.

There is no way to bind to this driver from firmware and no explicit
platform device creation calls exist in mainline.

As such it is dead code. So drop it rather than potentially wasting time
modernizing it (see #1)

Subject: [PATCH 2363/5214] docs: iio: triggered-buffers: use new helpers in
 example

Update the "typical" triggered buffer example to use various new helpers
that have been added in the last year or so. This reflects current
expectations of how similar code should be written.

Also zero-initialize the buffer so we don't leak stack data. And fix a
missing semicolon while we're at it.

Remove the SSP_CHAN_TIMESTAMP() macro and replace users with the
IIO_CHAN_SOFT_TIMESTAMP() macro. The SSP_CHAN_TIMESTAMP() macro is
identical to the IIO_CHAN_SOFT_TIMESTAMP() macro, so we don't need
a separate macro for it.

The driver only supports a single device type. So the return value of
i2c_get_match_data() is already known and can just be hardcoded without
type casting. While at it also remove the unused .data of the
single of_device_id entry.

Subject: [PATCH 2369/5214] iio: proximity: sx9360: Drop unused driver data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The value assigned in the three device_id entries (ACPI, of and i2c) are
unused, directly in the driver and also the sx_common support lib. Drop
them and while touching these arrays, convert to named initializers.

Subject: [PATCH 2370/5214] staging: iio: Use named initializers for struct
 i2c_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 2371/5214] iio: Initialize i2c_device_id arrays using member
 names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 2372/5214] iio: humidity: ens210: remove compiler warning
 workaround

Rewrite IIO_CHAN_INFO_RAW case to avoid needing to add unreachable code
to work around a compiler warning.

When scoped_guard() was first introduced, compilers could not see when
it returned unconditionally from inside the hidden for loop. This has
since been fixed in the macro definition. So removing the `return
-EINVAL` should be enough. Still, we can improve readability, decrease
indentation and avoid the hidden for loop by rewriting the case without
scoped_guard().

Subject: [PATCH 2373/5214] iio: imu: kmx61: Use guard(mutex)() over manual
 locking

Include linux/cleanup.h to take advantage of new macros.

Replace manual mutex_lock() and mutex_unlock() calls across the file
with guard(mutex)() and scoped_guard() where appropriate to simplify
error paths and eliminate manual locking calls.

Add new helper function kmx61_read_for_each_active_channel() to mitigate
certain style issues and to prevent notifying that the IRQ is finished
whilst holding the lock.

Update certain returns, and add default case to return -EINVAL in
kmx61_read_raw().

Remove now-redundant gotos and ret variables, as the new RAII macros
make them unneeded.

Two dev_err() calls in bno055_ser_write_reg() and bno055_ser_read_reg()
are missing the trailing newline, so the kernel log buffer continues
the next message on the same line.

Add the missing \n.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the local gyro_3d_adjust_channel_bit_mask() function with a
compound literal for scan_type initialization to improve code
readability. Additionaly, clean up the channel initialization
loop by iterating directly over the channel scan indices.

Subject: [PATCH 2381/5214] iio: tcs3472: power down chip on probe failure

If tcs3472_probe() fails after enabling the chip (by writing PON | AEN
to the ENABLE register), the error paths return without powering down
the device.

Add an 'error_powerdown' label at the end of the cleanup chain that
calls tcs3472_powerdown() to power down the chip. The existing label
cascade is rerouted to fall through to the new label.

Move tcs3472_powerdown() above tcs3472_probe() so the probe can call
it without a forward declaration.

Found by code inspection while reviewing the probe error paths in
preparation for the devm_ conversion.

Subject: [PATCH 2383/5214] iio: tcs3472: convert remaining locking to
 guard(mutex)

Convert several functions to use guard(mutex)()

This avoids manual unlock calls on each return path, drops the goto
in tcs3472_write_event(), and removes 'ret' variables only needed to
return after the unlock.

While the conversion is in progress, take the opportunity to make a
few small cleanups that guard() enables:

  - In tcs3472_read_event_config(), replace '!!(...)' with
    '(...) ? 1 : 0' for readability.

  - In tcs3472_write_event_config(), tcs3472_powerdown() and
    tcs3472_resume() use an early return on the I2C
    write failure path.

No functional change.

Subject: [PATCH 2385/5214] iio: tcs3472: use devm for resource management

Convert the driver to use device-managed resource allocation:
- Add tcs3472_powerdown_action() and register it with
  devm_add_action_or_reset() to ensure the device is powered down on
  cleanup.
- Replace iio_triggered_buffer_setup() with
  devm_iio_triggered_buffer_setup().
- Replace request_threaded_irq() with devm_request_threaded_irq().
- Replace iio_device_register() with devm_iio_device_register().
- Replace mutex_init() with devm_mutex_init().
- Remove tcs3472_remove() as all cleanup is now handled by devm.

Use a local 'dev = &client->dev' in tcs3472_probe() to keep the devm
calls compact.

Move the trailing 'return -EINVAL' statements at the end of

cases inside the respective switch statements.

This removes the need for a separate return statement

Subject: [PATCH 2388/5214] iio: chemical: sps30: Replace manual locking with
 RAII locking

Replace manual mutex_lock() and mutex_unlock() calls with the much newer
guard(mutex)() macro to enable RAII patterns, modernize the driver, and
to increase readability.

Move mutex locking into sps30_do_meas() and tune it up to use guard()(),
as every caller takes the lock anyways.

Subject: [PATCH 2389/5214] iio: Convert IIO_CHAN_SOFT_TIMESTAMP() to be
 compound literal

Currently IIO_CHAN_SOFT_TIMESTAMP() can only be used to fill the static
data.  In some cases it would be convenient to use it as right value in
the assignment operation. But it can't be done as is, because compiler
has no clue about the data layout. Converting it to be a compound literal
allows the above mentioned usage.

While at it, tidy up the indentation.

We also have to change existing uses of compound literal at the same
time to avoid compiler errors.

Subject: [PATCH 2390/5214] iio: common: scmi_sensors: simplify timestamp
 channel definition

Use IIO_CHAN_SOFT_TIMESTAMP() to define the timestamp channel instead of
manually filling in the struct iio_chan_spec fields. This makes the code
less verbose and mistake-prone.

In fact, there was an error here as the sign should be 's' instead of
'u' which is now changed to 's' by using IIO_CHAN_SOFT_TIMESTAMP().

If we find that this breaks userspace, we will have to revert this
change, but seems unlikely since the timestamp channel is well-known to
be a signed 64-bit integer globally.

Subject: [PATCH 2400/5214] dt-bindings: iio: light: add Broadcom APDS9999

Add Device Tree binding for the Broadcom APDS9999 ambient light
and proximity sensor. A separate binding file is used rather
than merging with avago,apds9300.yaml because the APDS9999
has an additional vcsel-supply for the VCSEL.

The APDS9999 features individual R, G, B, and IR channels with
a green channel that uses optical coating to approximate the
human eye spectral response for ALS/lux measurements. Calibrated
RGB color sensing is not yet implemented in the driver.

Subject: [PATCH 2401/5214] iio: light: add support for APDS9999 sensor

Add IIO driver for Broadcom APDS9999 ambient light sensor.

The APDS9999 is a digital proximity and RGB sensor with ALS
capability. The driver implements the ALS/Lux functionality
using the green channel, which uses optical coating technology
to approximate the human eye spectral response.

Raw IIO_INTENSITY channels are exposed for red, green, blue,
and IR so userspace can compute its own weighted lux.
Proximity (PS) support is not yet implemented.

Subject: [PATCH 2402/5214] iio: temperature: ltc2983: Fix n_wires default
 bypassing rotation check

When adi,number-of-wires is absent, n_wires is left at 0. The binding
documents a default of 2 wires, matching the hardware default. However
the current-rotate validation checks n_wires == 2 || n_wires == 3, so
with n_wires = 0 the guard is bypassed and adi,current-rotate is accepted
for a 2-wire RTD.

Initialize n_wires = 2 to match the binding default and ensure the
rotation check fires correctly when the property is absent.

Subject: [PATCH 2403/5214] iio: temperature: ltc2983: Fix reinit_completion()
 called after conversion start

reinit_completion() was called after regmap_write() initiated the hardware
conversion, creating a race window where the interrupt could fire and call
complete() before reinit_completion() reset the completion.

Move reinit_completion() before the regmap_write() to close the race.
ltc2983_eeprom_cmd() already does it in the correct order.

Subject: [PATCH 2404/5214] iio: temperature: ltc2983: Fix macro
 parenthesization and rename

Wrap the 'chan' parameter in LTC2983_CHAN_START_ADDR() and
LTC2983_CHAN_RES_ADDR() with parentheses to prevent potential
macro argument expansion issues. Also rename LTC2983_CHAN_START_ADDR
to LTC2983_CHAN_ASSIGN_ADDR and LTC2983_CHAN_RES_ADDR to
LTC2983_RESULT_ADDR, to better reflect the datasheet names and avoid
them being confused as related.

Subject: [PATCH 2405/5214] iio: temperature: ltc2983: Use local device pointer
 consistently

Some functions define a local 'dev' pointer but still use bare
'&st->spi->dev' in some code paths, and some don't have it at all.
Replace bare references with the local pointer for consistency and
collapse some wrapped lines that now fit within 80 characters.

Subject: [PATCH 2406/5214] iio: temperature: ltc2983: Fix inconsistent channel
 wording in messages

Replace occurrences of the abbreviated 'chann' and 'chan' with
'channel' in error and debug messages throughout the driver.
Also changed the diode invalid channel error message from
"thermistor" to "diode".

Subject: [PATCH 2407/5214] iio: temperature: ltc2983: Use
 fwnode_property_present() for optional properties

Checking fwnode_property_read_u32() return value with if (!ret)
silently swallows meaningful error codes when a property is present
but malformed. Use fwnode_property_present() first so that absence
uses the default while a present but unreadable property returns
a proper error.

Add a new channel type for sensors that report fractional coverage as
a percentage. The sysfs attribute is in_coverageY_raw; after applying
in_coverageY_scale the value is in percent. The first user is the
ADT7604 leak detector, where the value represents the portion of the
sensing element that is wetted.

Subject: [PATCH 2409/5214] dt-bindings: iio: temperature: Add ADT7604 support
 to adi,ltc2983

The ADT7604 shares the same die as the LTC2984. It repurposes the
custom RTD sensor type (18) as a copper trace resistance sensor
and the custom thermistor type (27) as a leak detector, and
removes thermocouple, diode and direct ADC sensor types.

Add adi,adt7604 to the compatible list and introduce two new
sensor node types specific to this device:

- copper-trace@: maps to the custom RTD sensor type (18). Two
variants: sub-ohm (< 1 ohm, adi,copper-trace-sub-ohm boolean,
no custom table and excitation current) and standard (> 1 ohm,
required adi,custom-copper-trace table, optional excitation current
defaulting to the datasheet recommended value). Primary output
is resistance in ohms. For > 1 ohm copper traces with a custom table,
the chip also outputs temperature in millidegrees Celsius.

- leak-detector@: maps to the custom thermistor sensor type (27).
Takes a required adi,custom-leak-detector lookup table encoding
resistance (uOhm) against coverage data (%). Two outputs:
resistance in ohms and coverage in percent.

Separate node types are used rather than extending the existing
rtd@ and thermistor@ nodes because adi,custom-rtd is required
for sensor type 18, and several properties (adi,number-of-wires,
adi,rtd-curve, adi,rsense-share, adi,single-ended,
adi,current-rotate) have no meaning for the new sensor types, since
the configuration is hardcoded, and would need to be explicitly
forbidden or ignored in the driver.

allOf conditions are added to restrict thermocouple, diode, direct
ADC and active temperature nodes to non-ADT7604 devices, and to
restrict copper-trace and leak-detector nodes to the ADT7604
(some parts only).

From 3dd0c048409e335320418c632966f149be628fd4 Mon Sep 17 00:00:00 2001
From: Liviu Stan <liviu.stan@analog.com>
Date: Mon, 25 May 2026 19:39:36 +0300
Subject: [PATCH 2410/5214] iio: temperature: ltc2983: Add support for ADT7604

The ADT7604 shares the same die as the LTC2984. It repurposes the
custom RTD sensor type (18) as a copper trace resistance sensor
and the custom thermistor type (27) as a leak detector, and
removes thermocouple, diode and direct ADC sensor types.

Two new software sensor type values are introduced
(LTC2983_SENSOR_COPPER_TRACE = 32, LTC2983_SENSOR_LEAK_DETECTOR = 33)
that map to the hardware register values 18 and 27 respectively.
Dedicated structs (ltc2983_copper_trace, ltc2983_leak_detector) and
parser functions are added rather than extending the existing RTD and
thermistor paths, as the hardware configuration bits are fully
hardcoded and several RTD/thermistor properties would need to be
explicitly forbidden or ignored.

Custom RTD (type 18) becomes the copper trace sensor. Sensor
configuration bits are hardcoded to 0b1001 per the datasheet.
Two variants are supported via the adi,copper-trace-sub-ohm DT
property: sub-ohm traces (< 1 ohm) have bits 17:0 cleared with no
excitation current or custom table; standard traces (> 1 ohm) have
a required resistance-to-temperature table.

Custom thermistor (type 27) becomes the leak detector. Sensor
configuration bits are hardcoded to 0b001. The custom table uses
a resolution of 16 instead of 64, and is specified via the
required adi,custom-leak-detector DT property.

Both sensor types expose an IIO_RESISTANCE channel reading from
the resistance result register bank (0x0060-0x00AF). Added a
"base" parameter to the LTC2983_RESULT_ADDR macro and a "base_reg"
parameter to the ltc2983_chan_read function so we can read from
both result register banks. The resistance register encodes the
measured resistance with 10 fractional bits, so dividing by 1024
gives ohms. Since the sense resistor is specified in ohms, the
output is in ohms for both sensor types and a single 1/1024
scale applies to both. For > 1 ohm copper traces and for leak
detectors, a secondary channel also appears: IIO_TEMP
(millidegrees Celsius) for copper trace and IIO_COVERAGE (percent)
for leak detector.

The ltc2983_chip_info struct is extended with a u64 supported_sensors
bitmask using BIT_ULL() to safely represent the new sensor type bits
32 and 33 on 32-bit builds. A LTC2983_SENSOR_NUM sentinel is added
to the enum so that the bounds check uses >= LTC2983_SENSOR_NUM
rather than hardcoding the last sensor type.

Tested on EVAL-ADT7604-AZ connected to Raspberry Pi 5 via SPI.

Subject: [PATCH 2411/5214] iio: Use named initializers for platform_device_id
 arrays
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Named initializers are better readable and more robust to changes of the
struct definition. This robustness is relevant for a planned change to
struct platform_device_id replacing .driver_data by an anonymous union.

Subject: [PATCH 2412/5214] light: tsl2591: simplify tsl2591_persist functions
 via lookup table

Replace switch statements with an indexed lookup table for
persist cycle conversions.

Both functions contain redundant switch statements. This
reduces code duplication and makes future updates to
TSL2591_PRST_ALS_INT_CYCLE_* definitions easier to maintain
by keeping the mapping in a single place.

Subject: [PATCH 2413/5214] dt-bindings: iio: adc: ad4080: add AD4884 support

Add AD4884 compatible string to the AD4080 devicetree binding.

The AD4884 is a dual-channel, 16-bit, 40 MSPS SAR ADC, sharing the same
register map and interface as the AD4080 family. Like the AD4880, it
requires two SPI chip selects and two io-backends for its independent
ADC channels. The AD4884 differs from the AD4880 in resolution (16-bit
vs 20-bit), which requires distinct channel configuration in the driver,
precluding a fallback compatible.

Subject: [PATCH 2415/5214] dt-bindings: iio: adc: add AD4691 family

Add DT bindings for the Analog Devices AD4691 family of multichannel
SAR ADCs (AD4691, AD4692, AD4693, AD4694).

The four variants are not compatible with each other: AD4691/AD4692 have
16 analog input channels while AD4693/AD4694 have 8, and AD4691/AD4693
top out at 500 kSPS while AD4692/AD4694 reach 1 MSPS. These differences
in channel count and maximum sample rate require distinct compatible
strings so the driver can select the correct channel configuration and
rate limits.

From 40850443aa1239f71fc65b870a0f0ecd54e42c9d Mon Sep 17 00:00:00 2001
From: Radu Sabau <radu.sabau@analog.com>
Date: Fri, 29 May 2026 13:15:01 +0300
Subject: [PATCH 2416/5214] iio: adc: ad4691: add initial driver for AD4691
 family
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for the Analog Devices AD4691 family of high-speed,
low-power multichannel SAR ADCs: AD4691 (16-ch, 500 kSPS),
AD4692 (16-ch, 1 MSPS), AD4693 (8-ch, 500 kSPS) and
AD4694 (8-ch, 1 MSPS).

The driver implements a custom regmap layer over raw SPI to handle the
device's mixed 1/2/3/4-byte register widths and uses the standard IIO
read_raw/write_raw interface for single-channel reads.

The chip idles in Autonomous Mode so that single-shot read_raw can use
the internal oscillator without disturbing the hardware configuration.

Three voltage supply domains are managed: avdd (required), vio, and a
reference supply on either the REF pin (ref-supply, external buffer)
or the REFIN pin (refin-supply, uses the on-chip reference buffer;
REFBUF_EN is set accordingly). Hardware reset is performed by asserting
then deasserting the reset-gpios GPIO line (tRESETL minimum pulse width
is 10 ns, satisfied by function-call overhead); the driver then waits
300 µs for the chip to complete its internal reset sequence. A software
reset via SPI_CONFIG_A is used as fallback when no reset GPIO is
provided.

Accumulator channel masking for single-shot reads uses ACC_MASK_REG via
an ADDR_DESCENDING SPI write, which covers both mask bytes in a single
16-bit transfer.

From 41297c6bd8dd04c0b23bd7b14e00632cc806688b Mon Sep 17 00:00:00 2001

Subject: [PATCH 2417/5214] iio: adc: ad4691: add triggered buffer support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add buffered capture support using the IIO triggered buffer framework.

CNV Burst Mode: the GP pin identified by interrupt-names in the device
tree is configured as DATA_READY output. The IRQ handler stops
conversions and fires the IIO trigger; the trigger handler executes a
pre-built SPI message that reads all active channels from the AVG_IN
accumulator registers and then resets accumulator state and restarts
conversions for the next cycle.

Manual Mode: CNV is tied to SPI CS so each transfer simultaneously
reads the previous result and starts the next conversion (pipelined
N+1 scheme). At preenable time a pre-built, optimised SPI message of
N+1 transfers is constructed (N channel reads plus one NOOP to drain
the pipeline). The trigger handler executes the message in a single
spi_sync() call and collects the results. An external trigger (e.g.
iio-trig-hrtimer) is required to drive the trigger at the desired
sample rate.

Both modes share the same trigger handler and push a complete scan —
one big-endian 16-bit (__be16) slot per active channel, densely packed
in scan_index order, followed by a timestamp.

The CNV Burst Mode sampling frequency (PWM period) is exposed as a
buffer-level attribute via IIO_DEVICE_ATTR.

Subject: [PATCH 2418/5214] iio: adc: ad4691: add SPI offload support

Add SPI offload support to enable DMA-based, CPU-independent data
acquisition using the SPI Engine offload framework.

When an SPI offload is available (devm_spi_offload_get() succeeds),
the driver registers a DMA engine IIO buffer and uses dedicated buffer
setup operations. If no offload is available the existing software
triggered buffer path is used unchanged.

Both CNV Burst Mode and Manual Mode support offload, but use different
trigger mechanisms:

CNV Burst Mode: the SPI Engine is triggered by the ADC's DATA_READY
signal on the GP pin specified by the trigger-source consumer reference
in the device tree (one cell = GP pin number 0-3). For this mode the
driver acts as both an SPI offload consumer (DMA RX stream, message
optimization) and a trigger source provider: it registers the
GP/DATA_READY output via devm_spi_offload_trigger_register() so the
offload framework can match the '#trigger-source-cells' phandle and
automatically fire the SPI Engine DMA transfer at end-of-conversion.

Manual Mode: the SPI Engine is triggered by a periodic trigger at
the configured sampling frequency. The pre-built SPI message uses
the pipelined CNV-on-CS protocol: N+1 16-bit transfers are issued
for N active channels (the first result is discarded as garbage from
the pipeline flush) and the remaining N results are captured by DMA.

All offload transfers use 16-bit frames (bits_per_word=16, len=2).
The SPI Engine assembles received bits into native 16-bit words before
DMA, so offload samples land in CPU-native byte order (IIO_CPU).
Dedicated channel arrays (AD4691_OFFLOAD_CHANNEL) reflect this: they
omit IIO_BE and carry no soft timestamp (DMA delivers data directly to
userspace). The software triggered-buffer path retains its IIO_BE
channels because bits_per_word=8 causes SPI to deliver bytes MSB-first
into memory, making the on-disk layout big-endian. Both paths use
storagebits=16 as transfers are 16 bits wide in both cases.

IIO_BUFFER_DMAENGINE is selected because the offload path uses
devm_iio_dmaengine_buffer_setup_with_handle() to allocate and
attach the DMA RX buffer to the IIO device.

Subject: [PATCH 2419/5214] iio: adc: ad4691: add oversampling support

Add oversampling ratio (OSR) support for CNV burst mode. The accumulator
depth register (ACC_DEPTH_IN(0)) is programmed with the selected OSR at
buffer enable time and before each single-shot read.

Supported OSR values: 1, 2, 4, 8, 16, 32.

Introduce AD4691_MANUAL_CHANNEL() for manual mode channels, which do
not expose the oversampling_ratio attribute since OSR is not applicable
in that mode. A separate manual_channels array is added to
struct ad4691_channel_info and selected at probe time.

The OSR is shared across all channels (in_voltage_sampling_frequency
and in_voltage_oversampling_ratio are info_mask_shared_by_all) because
the chip has one internal oscillator and a single accumulator depth
register (ACC_DEPTH_IN(0)) for all channels.

in_voltage_sampling_frequency represents the effective output rate,
defined as osc_freq / osr. Writing it computes needed_osc = freq * osr
and snaps down to the largest oscillator table entry that satisfies both
osc <= needed_osc and osc % osr == 0, guaranteeing an exact integer
read-back. The result is stored in target_osc_freq_Hz and written to
OSC_FREQ_REG at buffer enable and single-shot time, so sampling_frequency
and oversampling_ratio can be set in any order.

in_voltage_sampling_frequency_available is precomputed at probe for
each OSR value, listing only oscillator table entries that divide
evenly by that OSR, expressed as effective rates (osc_freq / osr).
The list becomes sparser as OSR increases, capping at max_rate / osr.
read_avail picks the precomputed list for the current OSR, making the
returned pointer stable and race-free.

Writing oversampling_ratio stores the new shared OSR and snaps
target_osc_freq_Hz to the largest oscillator table entry that is both
<= old_effective_rate * new_osr and evenly divisible by new_osr. This
preserves an integer read-back of in_voltage_sampling_frequency after
the OSR change while keeping the oscillator as close as possible to the
previous effective rate.

OSR defaults to 1 (no accumulation).

+AD4691 driver
+=============
+
+ADC driver for Analog Devices Inc. AD4691 family of multichannel SAR ADCs.
+The module name is ``ad4691``.
+
+
+Supported devices
+=================
+
+The following chips are supported by this driver:
+
+* `AD4691 <https://www.analog.com/en/products/ad4691.html>`_ — 16-channel, 500 kSPS
+* `AD4692 <https://www.analog.com/en/products/ad4692.html>`_ — 16-channel, 1 MSPS
+* `AD4693 <https://www.analog.com/en/products/ad4693.html>`_ — 8-channel, 500 kSPS
+* `AD4694 <https://www.analog.com/en/products/ad4694.html>`_ — 8-channel, 1 MSPS
+
+
+IIO channels
+============
+
+Each physical ADC input maps to one IIO voltage channel. The AD4691 and AD4692
+expose 16 channels (``voltage0`` through ``voltage15``); the AD4693 and AD4694
+expose 8 channels (``voltage0`` through ``voltage7``).
+
+All channels share a common scale (``in_voltage_scale``), derived from the
+reference voltage. Each channel exposes:
+
+* ``in_voltageN_raw`` — single-shot ADC result
+
+The following attributes are shared across all channels:
+
+* ``in_voltage_sampling_frequency`` — effective output rate, defined as the
+  internal oscillator frequency divided by the oversampling ratio. Writing this
+  attribute selects the nearest achievable rate for the current OSR; the value
+  read back reflects the actual rate after snapping to the closest valid
+  oscillator entry.
+* ``in_voltage_sampling_frequency_available`` — list of achievable effective
+  rates for the current oversampling ratio. The list updates dynamically when
+  the oversampling ratio changes.
+
+The following attributes are shared across all channels and only available in
+CNV Burst Mode:
+
+* ``in_voltage_oversampling_ratio`` — hardware oversampling depth applied to
+  all channels; see `Oversampling`_ below.
+* ``in_voltage_oversampling_ratio_available`` — valid ratios: 1, 2, 4, 8, 16,
+  32.
+
+
+Operating modes
+===============
+
+The driver supports two operating modes, selected automatically from the
+device tree at probe time.
+
+Manual Mode
+-----------
+
+Selected when no ``pwms`` property is present in the device tree. The CNV pin
+is tied to the SPI chip-select: every CS assertion triggers a conversion and
+returns the previous result. A user-defined IIO trigger (e.g. hrtimer trigger)
+drives the buffer.
+
+Oversampling is not supported in Manual Mode.
+
+CNV Burst Mode
+--------------
+
+Selected when a ``pwms`` property is present in the device tree. A PWM drives
+the CNV pin at the configured conversion rate. A GP pin wired to the SoC and
+declared in the device tree signals DATA_READY at the end of each burst,
+triggering a readout of all active channel results into the IIO buffer.
+
+The buffer output rate is controlled by the ``sampling_frequency`` attribute
+on the IIO buffer. In practice the PWM rate should be set low enough to allow
+the SPI readout to complete before the next conversion burst begins.
+
+Autonomous Mode (idle / single-shot)
+-------------------------------------
+
+When the IIO buffer is disabled, ``in_voltageN_raw`` reads perform a single
+conversion on the requested channel using the internal oscillator. The
+oscillator is started and stopped around each read to save power.
+
+
+Oversampling
+============
+
+In CNV Burst Mode a shared hardware accumulator averages a configurable number
+of successive conversions across all active channels. The result is always a
+16-bit mean, so the buffer data type (shown in ``buffer0/in_voltageN_type``)
+is unaffected by the oversampling ratio. Valid ratios are 1, 2, 4, 8, 16 and
+32; the default is 1 (no averaging). Oversampling is not supported in Manual
+Mode.
+
+.. code-block:: bash
+
+    # Set oversampling ratio to 16 (shared across all channels)
+    echo 16 > /sys/bus/iio/devices/iio:device0/in_voltage_oversampling_ratio
+
+    # Read the resulting effective sampling frequency
+    cat /sys/bus/iio/devices/iio:device0/in_voltage_sampling_frequency
+
+Writing ``in_voltage_oversampling_ratio`` stores the new shared depth and snaps
+the internal oscillator to the largest valid table entry that is both less than
+or equal to ``old_effective_rate × new_osr`` and evenly divisible by
+``new_osr``. This preserves an integer read-back of
+``in_voltage_sampling_frequency`` after the change and keeps the oscillator as
+close as possible to the previous effective rate.
+
+
+Reference voltage
+=================
+
+The driver supports two reference configurations, mutually exclusive:
+
+* **External reference** (``ref-supply``): a voltage between 2.4 V and 5.25 V
+  supplied externally.
+* **Buffered internal reference** (``refin-supply``): an internal reference
+  buffer is enabled by the driver.
+
+Exactly one of ``ref-supply`` or ``refin-supply`` must be present in the
+device tree. The reference voltage determines the full-scale range reported
+via ``in_voltage_scale``.
+
+
+LDO supply
+==========
+
+The chip contains an internal LDO that powers part of the analog front-end.
+The supply configuration is mutually exclusive:
+
+* **External VDD** (``vdd-supply``): an external 1.8 V supply is used directly;
+  the internal LDO is disabled.
+* **Internal LDO** (``ldo-in-supply``): the internal LDO is enabled and fed
+  from the ``ldo-in`` regulator. Use this when no external 1.8 V VDD is present.
+
+Exactly one of ``vdd-supply`` or ``ldo-in-supply`` must be provided.
+
+
+Reset
+=====
+
+The driver supports two reset mechanisms:
+
+* **Hardware reset** (``reset-gpios`` in device tree): the GPIO line is
+  asserted then deasserted at probe; the driver waits 300 µs for the chip
+  to complete its internal reset sequence before accepting SPI commands.
+* **Software reset** (fallback when ``reset-gpios`` is absent): written
+  automatically at probe.
+
+
+GP pins and interrupts
+======================
+
+The chip exposes up to four general-purpose (GP) pins. In CNV Burst Mode
+(non-offload), one GP pin must be wired to an interrupt-capable SoC input and
+declared in the device tree using the ``interrupts`` and ``interrupt-names``
+properties. The ``interrupt-names`` value identifies which GP pin is used
+(``"gp0"`` through ``"gp3"``).
+
+Example device tree fragment::
+
+    adc@0 {
+        compatible = "adi,ad4692";
+        ...
+        interrupt-parent = <&gpio0>;
+        interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
+        interrupt-names = "gp0";
+    };
+
+
+SPI offload support
+===================
+
+When a SPI offload engine (e.g. the AXI SPI Engine) is present, the driver
+uses DMA-backed transfers for CPU-independent, high-throughput data capture.
+SPI offload is detected automatically at probe; if no offload hardware is
+available the driver falls back to the software triggered-buffer path.
+
+Two SPI offload sub-modes exist:
+
+CNV Burst offload
+-----------------
+
+Used when a ``pwms`` property is present and SPI offload is available. The PWM
+drives CNV at the configured rate; on DATA_READY the offload engine reads all
+active channel results and streams them directly to the IIO DMA buffer with no
+CPU involvement. The GP pin used as DATA_READY trigger is supplied by the
+trigger-source consumer at buffer enable time; no ``interrupt-names`` entry is
+required.
+
+Manual offload
+--------------
+
+Used when no ``pwms`` property is present and SPI offload is available. A
+periodic SPI offload trigger controls the conversion rate and the offload engine
+streams results directly to the IIO DMA buffer.
+
+The ``sampling_frequency`` attribute on the IIO buffer controls the trigger
+rate (in Hz). The initial rate is 100 kHz.
+
+Oversampling is not supported in Manual Mode.
+
+
+Buffer data format
+==================
+
+The sample format in the IIO buffer depends on whether SPI offload is in use.
+
+Software triggered-buffer path (no SPI offload)
+------------------------------------------------
+
+Each active channel occupies one 16-bit big-endian slot (``storagebits=16``,
+``endianness=be``). Active channels are packed densely in scan-index order,
+followed by a 64-bit software timestamp appended by the IIO core.
+
+SPI offload path
+----------------
+
+Each active channel occupies one 16-bit CPU-native slot (``storagebits=16``,
+``endianness=cpu``). The SPI offload engine streams 16-bit words directly from
+the SPI Engine into the DMA buffer; no software timestamp is appended.

Subject: [PATCH 2421/5214] media: qcom: camss: vfe-340: Support for PIX client

Add support for the vfe-340 PIX write engine, enabling frame capture
through the PIX video device (e.g. msm_vfe0_pix). The PIX path requires
a separate configuration flow from RDI, including cropping setup, line-
based write engine configuration, and the correct packer format based
on the input pixel format.

In contrast to RDI, the PIX interface embeds a lightweight processing
engine we can use for cropping, configuring custom stride/alignment,
and, in the future, extracting frame statistics.

The functionality has been validated on Arduino-Uno-Q with:
media-ctl -d /dev/media0 --reset
media-ctl -d /dev/media0 -l '"msm_csiphy0":1->"msm_csid0":0[1],"msm_csid0":4->"msm_vfe0_pix":0[1]'

Subject: [PATCH 2422/5214] clk: at91: keep securam node alive while mapping it

pmc_register_ops() gets an owned reference to the
"atmel,sama5d2-securam" node with of_find_compatible_node().  The
success path dropped that reference before passing the node to
of_iomap(), leaving of_iomap() to consume a node pointer after the caller
had released its reference.

Move of_node_put() after of_iomap() so the node remains referenced for
the mapping operation.  The unavailable-node error path already releases
the reference.

Subject: [PATCH 2423/5214] RISC-V: KVM: Batch stage-2 TLB flushes

KVM RISC-V triggers a TLB flush for every single stage-2 PTE
modification (unmap or write-protect) now. Although KVM coalesces the
hardware IPIs, the software overhead of executing the flush work
for every page is large, especially during dirty page tracking.

Following the approach used in x86 and arm64, this patch optimizes
the MMU logic by making the PTE manipulation functions return a boolean
indicating if a leaf PTE was actually changed. The outer MMU functions
bubble up this flag to batch the remote TLB flushes.

Consequently, the flush operation is executed only once per batch.
Moving it outside of the `mmu_lock` also reduces lock contention.

Tested with tools/testing/selftests/kvm on a 4-vCPU guest (Host
environment: QEMU 10.2.1 RISC-V)
1. demand_paging_test (1GB memory)
  time ./demand_paging_test -b 1G -v 4
- Total execution time reduced from ~2m39s to ~2m31s
2. dirty_log_perf_test (1GB memory)
  ./dirty_log_perf_test -b 1G -v 4
- "Clear dirty log time" per iteration dropped significantly from
   ~3.40s to ~0.18s

Subject: [PATCH 2424/5214] kho: fix deferred initialization of scratch areas

Currently, if CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled,
kho_release_scratch() will initialize the struct pages and set migratetype
of KHO scratch. Unless the whole scratch fits below first_deferred_pfn,
some of that will be overwritten either by deferred_init_pages() or
memmap_init_reserved_range().

To fix it, make memmap_init_range(), deferred_init_memmap_chunk() and
__init_page_from_nid() recognize KHO scratch regions and set
migratetype of pageblocks in those regions to MIGRATE_CMA.

Subject: [PATCH 2425/5214] kho: make preserved pages compatible with deferred
 struct page init

When CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, struct page
initialization is deferred to parallel kthreads that run later
in the boot process.

During KHO restoration, kho_preserved_memory_reserve() writes metadata
for each preserved memory region. However, if the struct page has not
been initialized, this write targets uninitialized memory, potentially
leading to errors like:
BUG: unable to handle page fault for address: ...

Fix this by introducing kho_get_preserved_page(),  which ensures
all struct pages in a preserved region are initialized by calling
init_deferred_page() which is a no-op when the struct page is already
initialized.

Subject: [PATCH 2429/5214] liveupdate: add LIVEUPDATE_SESSION_GET_NAME ioctl

Userspace when requesting a session via the ioctl specifies a name and
gets a FD, but then there is no ioctl to go back the other way and get
the name given a LUO session FD. This is problematic especially when
there is a userspace orchestrator that wants to check what FDs it is
handling for clients without having to do manual string scraping of
procfs, or without procfs at all.

Add a ioctl to simply get the name from an FD.

Subject: [PATCH 2432/5214] liveupdate: Reference count incoming FLB data

Increment the incoming FLB refcount in liveupdate_flb_get_incoming() so
that the FLB structure cannot be freed while the caller is actively using
it. Add an additional liveupdate_flb_put_incoming() function so the
caller can explicitly indicate when it is done using the FLB data.

During a Live Update, a subsystem might need to hold onto the incoming
File-Lifecycle-Bound (FLB) data for an extended period, such as during
device enumeration. Incrementing the reference count guarantees that the
data remains valid and accessible until the subsystem releases it,
preventing future use-after-free bugs.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

kho_scratch_migratetype(), defined in include/linux/memblock.h uses enum
migratetype. This breaks build for memblock tests with:

./linux/memblock.h:634:73: error: parameter 2 (‘mt’) has incomplete type

Fix it by defining enum migratetype and MIGRATE_CMA. As is the case with
the other headers in tools/testing/memblock, do not bring in the whole
thing, only what is needed.

Subject: [PATCH 2434/5214] ring-buffer: Better comment the use of
 RB_MISSED_EVENTS

If the persistent ring buffer is detected on boot up to have a corrupted
sub-buffer, that sub-buffer is cleared to zero and its commit value has
the RB_MISSED_EVENTS bit set. That bit is to allow the "trace",
"trace_pipe" and "trace_pipe_raw" files know that events were dropped by
outputting "[LOST EVENTS]".

Only in this case does that bit get set in the writeable portion of the
ring buffer. When events are dropped in the normal ring buffer, that
information is stored in the cpu_buffer descriptor and the
RB_MISSED_EVENTS is set in the buffer page at the time the page is
consumed. It is never set in the writeable portion of the buffer.

Add comments to describe this better as it can be confusing to know when
the RB_MISSED_EVENTS are set in the commit portion of the buffer page.

Subject: [PATCH 2435/5214] fpga: dfl: add bounds check in dfh_get_param_size()

dfh_get_param_size() can return a parameter size larger than the feature
region because the loop bounds check is evaluated before incrementing
size. If the EOP (End of Parameters) bit is set in the same iteration,
the inflated size is returned without re-validation against max.

This can cause create_feature_instance() to call memcpy_fromio() with a
size exceeding the ioremap'd region when a malicious FPGA device provides
crafted DFHv1 parameter headers.

Add a bounds check after the size increment to ensure the accumulated
size never exceeds the feature boundary.

afu_ioctl_dma_map() accepts a 64-bit length from userspace via
DFL_FPGA_PORT_DMA_MAP ioctl without an upper bound check. The value
is passed to afu_dma_pin_pages() where npages is derived as
length >> PAGE_SHIFT and passed to pin_user_pages_fast() which takes
int nr_pages, causing implicit truncation if length is very large.

Validate map.length at the ioctl entry point before calling

Subject: [PATCH 2437/5214] fpga: microchip-spi: fix zero header_size OOB read
 in mpf_ops_parse_header()

mpf_ops_parse_header() reads header_size from the bitstream at
MPF_HEADER_SIZE_OFFSET (24). When header_size is zero, the expression
*(buf + header_size - 1) reads one byte before the buffer start.

Since initial_header_size is set to 71 in mpf_ops, the fpga-mgr core
guarantees the buffer is large enough to reach MPF_HEADER_SIZE_OFFSET.
The only real gap is the zero header_size case, which cannot be
resolved by providing a larger buffer, so return -EINVAL.

Subject: [PATCH 2438/5214] liveupdate: validate session type before performing
 operation

The sessions ioctls are not applicable to all session types. PRESERVE_FD
is only applicable to outgoing sessions. RETRIEVE_FD and FINISH are only
valid for incoming session. Calling a incoming ioctl on an outgoing
session is invalid and can cause file handlers to run into unexpected
errors.

For example, a user can create a (outgoing) session, preserve a memfd,
and then immediately do a retrieve without doing a kexec in between.
This would result in memfd's retrieve handler to run. The handlers
expects to be called from a post-kexec context, and will try to do a
kho_restore_vmalloc() or kho_restore_folio() to try and restore memory.

KHO catches this (thanks to KHO_PAGE_MAGIC) and returns an error, but
since this is considered an internal error and KHO throws out a bunch of
WARN()s.

Associate a type with each ioctl op and validate the type in
luo_session_ioctl() before dispatching the ioctl handler to make sure
the op is being called for the right session type.

While the liveupdate= parameter is documented in kernel-parameters.txt,
it is not listed in LUO's user facing documentation. This can make it
hard for users to figure out how to enable the subsystem, since enabling
just the config isn't enough.

Note the need for the kernel parameter in LUO core documentation, which
gets exported to Documentation/core-api/liveupdate.rst.

When using scratch_scale, the scratch sizes are rounded up to
CMA_MIN_ALIGNMENT_BYTES since they will be released as MIGRATE_CMA. This
is not done when using fixed scratch sizes via command line. This can
result in user specifying a size which is not aligned, and thus kernel
releasing a pageblock that is only partially scratch.

Do the rounding up for both cases in scratch_size_update().

+=====================
+
+systemd (since version v261) uses LUO to preserve its per-service file
+descriptor store across a kexec-based live update. Services opt in by setting
+``FileDescriptorStoreMax=`` and ``FileDescriptorStorePreserve=`` in their unit,
+and push file descriptors with a name into the store via
+``sd_pid_notify_with_fds(... "FDSTORE=1\nFDNAME=foo")``.
+
+Services may also create their own LUO sessions (via ``/dev/liveupdate``) and
+push the resulting session fds into their file descriptor store like any other
+fd. systemd detects such session fds and handles them accordingly, and
+hands the re-retrieved session fd back to the service after kexec, using the
+existing file descriptor store service interface.

Subject: [PATCH 2445/5214] liveupdate: fix TOCTOU race in
 luo_session_retrieve()

Extend the scope of the rwsem_read lock in luo_session_retrieve() to
overlap with the acquisition of the session mutex. This prevents a
concurrent thread from releasing and freeing the session between the
lookup and the mutex lock.

Subject: [PATCH 2446/5214] liveupdate: block session mutations during reboot

During the reboot() syscall, user processes may still be running
concurrently and attempting to mutate sessions (e.g., creating,
retrieving, or releasing sessions). To prevent this, introduce
luo_session_serialize_rwsem to synchronize mutations with the
serialization process.

All session mutation operations (create, retrieve, release, ioctl) take
the read lock. The serialization process (luo_session_serialize) takes
the write lock and holds it indefinitely on success. This effectively
freezes the LUO session subsystem during the transition to the new
kernel. If serialization fails, the lock is released to allow recovery.

Subject: [PATCH 2447/5214] liveupdate: fix u-a-f in
 luo_file_unpreserve_files() and luo_file_finish()

In luo_file_unpreserve_files() and luo_file_finish(), reorder
module_put() and xa_erase() to ensure the file handler module remains
pinned while its operations are being accessed.

Specifically, luo_get_id() dereferences fh->ops->get_id, so the module
reference must be held until after xa_erase() (which calls luo_get_id)
completes.

For luo_file_finish(), this requires moving the module_put() call out of
the luo_file_finish_one() helper and into the main loop of
luo_file_finish() itself.

 luo_session

The ser field in struct luo_session was intended to point to the
serialized data for a session, but it was never actually utilized in the
implementation. All serialization and deserialization logic consistently
uses the pointers maintained in struct luo_session_header.

Remove the dead field to clean up the structure.

Subject: [PATCH 2452/5214] nvdimm/btt: Handle preemption in BTT lane
 acquisition

BTT lanes serialize access to per-lane metadata and workspace state
during BTT I/O. The btt-check unit test reports data mismatches during
BTT writes due to a race in lane acquisition that can lead to silent
data corruption.

The existing lane model uses a spinlock together with a per-CPU
recursion count. That recursion model stopped being valid after BTT
lanes became preemptible: another task can run on the same CPU,
observe a non-zero recursion count, bypass locking, and use the same
lane concurrently.

BTT lanes are also held across arena_write_bytes() calls. That path
reaches nsio_rw_bytes(), which flushes writes with nvdimm_flush().
Some provider flush callbacks can sleep, making a spinlock the wrong
primitive for the lane lifetime.

Replace the spinlock-based recursion model with a dynamically
allocated per-lane mutex array and take the lane lock
unconditionally.

Add might_sleep() to catch any future atomic-context caller.

Found with the ndctl unit test btt-check.sh.

platform_device_id to zero without relying on that value. Drop this

While touching this array unify spacing, use a named initializer for
.name and drop trailing commas after the list terminators.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make the poweroff driver for SC27xx-series PMICs probe automatically.
Since the device representing the poweroff functionality of the SC27xx
PMIC is not supposed to have a dedicated device tree node without any
corresponding DT resources [1], an of_device_id table cannot be used
here. Instead, use a platform_device_id table to match the poweroff
sub-device instantiated by the parent MFD driver.

Memory allocated by btt_freelist_init(), btt_rtt_init(), and
btt_maplocks_init() is not freed on some discover_arenas() error
paths. This leaks memory when arena discovery fails.

Add the missing kfree() calls to release the allocations before
returning an error.

Subject: [PATCH 2461/5214] dax/bus: Upgrade resource conflict message to
 dev_err() in alloc_dax_region()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dax_region resource conflict in alloc_dax_region() indicates a
serious configuration problem — two subsystems (e.g. dax_hmem and
dax_cxl) are attempting to register overlapping address ranges. This is
not a transient or debug-level condition; it represents a genuine
resource conflict that an administrator needs to be aware of.

Promote the log level from dev_dbg() to dev_err() so that the conflict
is visible by default without requiring dynamic debug to be enabled.

Subject: [PATCH 2466/5214] scsi: smartpqi: Use shost_to_hba() in
 pqi_scan_finished()

shost_to_hba() is used everywhere except to obtain pqi_ctrl_info from
shosti, except in pqi_scan_finished(), where shost_priv() is used.  This
causes one pointer dereference to be missed, as shost->hostdata is a
pointer in smartpqi. Fix it.

Subject: [PATCH 2467/5214] scsi: Revert "scsi: Fix sas_user_scan() to handle
 wildcard and multi-channel scans"

This reverts commit 37c4e72b0651e7697eb338cd1fb09feef472cc1a.

Said commit causes excessive resource usage and even system freeze with
some controllers, e.g. smartpqi and hisi_sas. The justification provided
by the patch authors [1] was supporting a special mode of the mpi3mr and
mpt3sas, so-called "Tri-mode", in which NVMe drives are exposed as SCSI
devices on a separate channel. While that's useful for these drivers, it
seems wrong to cause major breakage for other drivers for the sake of
this feature.

Subject: [PATCH 2468/5214] scsi: sas: Skip opt_sectors when DMA reports no
 real optimization hint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sas_host_setup() unconditionally sets shost->opt_sectors from
dma_opt_mapping_size().

When the IOMMU is disabled or in passthrough mode and no DMA ops provide
an opt_mapping_size callback, dma_opt_mapping_size() returns
min(dma_max_mapping_size(), SIZE_MAX) which equals
dma_max_mapping_size() — a hard upper bound, not an optimization hint.

On a Dell PowerEdge R750 with mpt3sas (Broadcom SAS3816, FW 33.15.00.00)
and intel_iommu=off the following values are observed:

  dma_opt_mapping_size()  = dma_max_mapping_size() (no real hint)
  shost->max_sectors      = 32767
  opt_sectors             = min(32767, huge >> 9) = 32767
  optimal_io_size         = 32767 << 9 = 16776704
                          → round_down(16776704, 4096) = 16773120

The SAS disk (SAMSUNG MZILT800HBHQ0D3) does not report an Optimal
Transfer Length in VPD page B0, so sdkp->opt_xfer_blocks remains 0.

sd_revalidate_disk() then uses min_not_zero(0, opt_sectors) =
opt_sectors, propagating the bogus value into the block device's
optimal_io_size (visible as OPT-IO = 16773120 in lsblk --topology).

mkfs.xfs picks up optimal_io_size and minimum_io_size and computes:

  swidth = 16773120 / 4096 = 4095
  sunit  = 8192 / 4096     = 2

Since 4095 % 2 != 0, XFS rejects the geometry:

  SB stripe unit sanity check failed

This makes it impossible to create XFS filesystems (e.g. for
/var/lib/docker) during system bootstrap.

Fix this by introducing a sas_dma_setup_opt_sectors() helper that sets
opt_sectors only when dma_opt_mapping_size() is strictly less than
dma_max_mapping_size(), indicating a genuine DMA optimization
constraint.

The helper computes min(opt_sectors, max_sectors) first, then rounds
down to a power of two so that filesystem geometry calculations always
produce clean results.

When the two DMA values are equal, no backend provided a real hint, so
opt_sectors stays at 0 ("no preference").

[mkp: implemented hch's suggestion]

Subject: [PATCH 2469/5214] scsi: ufs: core: Skip link param validation when
 lanes_per_direction is unset

ufshcd_validate_link_params(), added by commit e72323f3b09f ("scsi: ufs:
core: Configure only active lanes during link"), is called
unconditionally from ufshcd_link_startup() and fails link startup with
-ENOLINK when the connected lane count read from the device differs from
hba->lanes_per_direction.

lanes_per_direction is only set by ufshcd-pltfrm (default 2, or the
"lanes-per-direction" devicetree property); ufshcd-pci controllers
(e.g. Intel) leave it 0. As the device always reports >= 1 connected
lanes, the check can never match and link startup always fails.
Reproduced with QEMU's UFS device.

Skip the check when lanes_per_direction is unset: with no expected value
to validate against, restore the behaviour from before that commit.

Subject: [PATCH 2471/5214] scsi: pm8001: Fix error code in
 non_fatal_log_show()

The non_fatal_log_show() function is supposed to return negative error
codes on failure.  But because the error codes are saved in a u32 and
then cast to signed long, they end up being high positive values instead
of negative.  Remove the intermediary u32 variable to fix this bug.

Subject: [PATCH 2473/5214] scsi: ufs: core: Fix NULL pointer dereference in
 scsi_cmd_priv() calls

ufshcd_tag_to_cmd() may return NULL if no command is associated with the
given tag. However, several callers dereference the returned cmd pointer
via scsi_cmd_priv() without checking for NULL first, leading to a
potential NULL pointer dereference.

Fix this by adding NULL checks for cmd before calling scsi_cmd_priv()
and moving the lrbp initialization after the NULL check.

 UPIU response case

In ufshcd_transfer_rsp_status(), the default case of the inner switch
statement prints the UPIU response code when an unexpected response is
received. However, the code was printing 'result' variable which is
always 0 at that point, making the error message useless for debugging.

Fix this by printing the actual UPIU response code returned by
ufshcd_get_req_rsp().

These are the remaining PowerPC devicetrees that do not have a /model
property, even though it is required by the devicetree specification.
Fix them by simply copying the compatible string.

Subject: [PATCH 2481/5214] powerpc: dts: Build devicetrees of enabled
 platforms
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow the same approach as other architectures such as Arm or RISC-V,
and build devicetrees based on platforms selected in Kconfig. This makes
it unnecessary to use CONFIG_OF_ALL_DTBS on PowerPC in order to build
DTB files.

This makes it easier to use other build and test infrastructure such as
`make dtbs_check`, and is a first step towards generating FIT images
that include all the relevant DTBs with `make image.fit`.

Subject: [PATCH 2482/5214] powerpc64/bpf: Add powerpc64 JIT support for timed
 may_goto

When verifier sees a timed may_goto instruction, it emits a call to
arch_bpf_timed_may_goto() with a stack offset in BPF_REG_AX
(powerpc64 R12) and expects the refreshed count value to be returned
in the same register. The verifier doesn't save or restore any registers
before emitting this call.

arch_bpf_timed_may_goto() should act as a trampoline to call
bpf_check_timed_may_goto() with powerpc64 ELF ABI calling convention.

To support this custom calling convention, implement
arch_bpf_timed_may_goto() in assembly and make sure BPF caller saved
registers are preserved, then call bpf_check_timed_may_goto with
the powerpc64 ABI calling convention where first argument and return
value both are in R3. Finally, move the result back into BPF_REG_AX(R12)
before returning.

Also, introduce bpf_jit_emit_func_call() that computes the offset from
kernel_toc_addr(), validates that the target and emits the ADDIS/ADDI
sequence to load the function address before performing the indirect
branch via MTCTR/BCTRL. The existing code in bpf_jit_emit_func_call_rel()
is refactored to use this function.

Subject: [PATCH 2483/5214] powerpc/fadump: Add timeout to RTAS busy-wait loops

The ibm,configure-kernel-dump RTAS call sites in
rtas_fadump_register(), rtas_fadump_unregister(), and
rtas_fadump_invalidate() polled indefinitely while firmware returned
a busy status. A misbehaving or hung firmware could stall these paths
forever, blocking fadump registration at boot or preventing clean
teardown.

Introduce rtas_fadump_call(), a helper that wraps the common
busy-wait pattern shared by all three sites. The helper accumulates
the total delay and returns -ETIMEDOUT if firmware keeps returning a
busy status beyond RTAS_FADUMP_MAX_WAIT_MS (60 seconds). A pr_debug()
message is emitted on each busy iteration to aid diagnosis when the
timeout is hit.

Replace it, No change in functionality or performance.
Slightly simpler code.

Subject: [PATCH 2486/5214] powerpc/perf: Use cpumask_intersects api for
 checking disable path

First online CPU in the node disables the nest counters by
making an OPAL call. Any other CPU in that node, will bail out.

Instead of using a temporary mask to find out if any cpu in the
node is visited or not, it is better to use the cpumask_intersects
api to achieve the same.

Similarly a temporary cpumask is used to check if a core is already part
of core_imc_cpumask. Use the same cpumask_intersects api there.

This is a very rare case, which either means mask was empty or

kmsg_dump_desc() in the panic path. As a result, kmsg_dumpers such as
pstore are not executed during fadump crashes.

This is problematic because pstore provides a critical fallback mechanism
for crash analysis. When fadump fails to successfully reboot the system
or capture a dump, pstore logs may be the only available information from
the crashed kernel. Without invoking kmsg_dump_desc() in the fadump path,
we lose this valuable diagnostic data.

Invoke kmsg_dump_desc() from the fadump panic handler, but only when
fadump is actually registered (checked via should_fadump_crash()). This
ensures kmsg_dumpers are called without duplicating the call that occurs
later in panic() when fadump is not active.

The call is placed before crash_fadump() to ensure logs are captured
before the system attempts to trigger the firmware-assisted dump.

Subject: [PATCH 2489/5214] MAINTAINERS: powerpc: update VMX AES entries

Commit 7cf2082e74ce ("lib/crypto: powerpc/aes: Migrate POWER8 optimized
code into library") removed arch/powerpc/crypto/aes.c and moved
arch/powerpc/crypto/aesp8-ppc.pl to lib/crypto/powerpc/.

However, the "IBM Power VMX Cryptographic instructions" entry still
references the removed file and no longer covers the moved aesp8-ppc.pl.

Remove the stale entry, add lib/crypto/powerpc/aesp8-ppc.pl, and tighten
the arch/powerpc/crypto/aesp8-ppc.* pattern to match the remaining
header only.

Subject: [PATCH 2490/5214] powerpc: use sysfs_emit{_at} in sysfs show
 functions

Replace sprintf() with sysfs_emit() and sysfs_emit_at() in sysfs show
functions, which are preferred for formatting sysfs output because they
provide safer bounds checking.

While the current code only emits strings that fit easily within
PAGE_SIZE, use sysfs_emit() and sysfs_emit_at() to follow secure coding
best practices.

This is a mechanical cleanup with a few simple edge cases:

- In domains_show(), drop the redundant n < 0 check since neither
  sprintf() nor sysfs_emit() return negative values.

- In powercap_show() and psr_show(), also drop the dead ret < 0 checks.

- In ps3_fw_version_show(), normalize the output by adding a terminating
  newline as suggested by checkpatch.

- In vio's modalias_show(), replace the deprecated strcpy() [1] followed
  by strlen() with sysfs_emit().

Leave validate_show() and the variable-length hv-gpci helpers unchanged
since they already have explicit bounds handling, and converting those
would be more than a mechanical conversion.

Subject: [PATCH 2493/5214] powerpc/pseries/lparcfg: Replace deprecated strcpy
 in parse_system_parameter_string

strcpy() is deprecated; use strscpy() instead. Use the return value of
strscpy() instead of calling strlen() again, and ignore any potential
string truncation since both strings are much shorter than the buffer
size SPLPAR_MAXLENGTH.

Change both if conditions to silence the following checkpatch warnings:

  Comparisons should place the constant on the right side of the test

Subject: [PATCH 2494/5214] clk: spacemit: k3: Switch to pll2_d6 as parent for
 PCIe clock

According to SpacemiT updated docs, the PCIe master and slave clock's
parent is the pll2_d6 clock, so fix it.

Fixes: e371a77255b8 ("clk: spacemit: k3: add the clock tree")

Subject: [PATCH 2499/5214] iio: adc: ad4080: fix AD4880 chip ID

The AD4880 chip ID was incorrectly set to 0x0750. According to the
datasheet, the product ID registers read 0x00 (PRODUCT_ID_H) and 0x59
(PRODUCT_ID_L), giving a combined chip ID of 0x0059. Fix the value to
match the actual hardware.

Subject: [PATCH 2501/5214] iio: dac: ad5686: remove redundant register
 definition

AD5683_REGMAP and AD5693_REGMAP behave the same way in the common code,
and that is because they target single channel devices from the same
sub-family. There is no reason to separate them and it will make things
simpler when refactoring the chip info table.

Subject: [PATCH 2502/5214] iio: dac: ad5686: drop enum id

Split chip info table into separate structs and expose them to the spi
i2c drivers. That is the preferrable approach and allows for the drivers
to have knowledge of the device info before the common probe function gets
called. Those chip info structs may be shared by SPI and I2C driver
variants.
Channel declaration definitions are grouped according to channel count and
DECLARE_AD5693_CHANNELS() macro is renamed to DECLARE_AD5683_CHANNELS() to
match the regmap_type enum.
Use spi_get_device_match_data() and i2c_get_match_data() to get chip info
struct reference, passing it as parameter to the core probe function.

Subject: [PATCH 2504/5214] iio: dac: ad5686: add helpers to handle powerdown
 masks

Add ad5686_pd_field_set() and ad5686_pd_field_get() helpers to cleanup
powerdown mask control. Define AD5686_PD_* constants, e.g. AD5686_PD_MSK
to hold powerdown mask value for a single channel. AD5686_LDAC_PWRDN_*
macros are replaced by AD5686_PD_MODE_*, because they are unused and the
LDAC feature for async load of DAC channel values is not related to power
down control.

Subject: [PATCH 2505/5214] iio: dac: ad5686: add control_sync() for
 single-channel devices

Create ad5310_control_sync() and ad5683_control_sync() functions that
properly consume the mask definitions with FIELD_PREP(). This allows to
reuse a function that updates the control register with cached values,
without relying on confusing logic that depends on st->use_internal_vref,
which is initialized earlier in ad5686_probe() because it is also
applicable to the AD5686_REGMAP case, removing the need for the
has_external_vref. Powerdown masks initialization is simplified as
*_control_sync() masks outs any unused bits for the single-channel case.
The change cleans up ad5686_write_dac_powerdown() and ad5686_probe(),
organizing the code for feature extension, e.g. gain control support for
single-channel devices.

Create struct with bus operations, which will be used to extend bus
implementation features. Auxiliary functions ad5686_write() and
ad5686_read() are created and ad5686_probe() now receives an ops struct
pointer rather than individual read and write functions.

Subject: [PATCH 2508/5214] fs/ntfs3: add bounds check to run_get_highest_vcn()

run_get_highest_vcn() parses a packed NTFS mapping-pairs buffer without
any length bound, relying solely on a 0x00 terminator to stop.  A
crafted $LogFile UpdateMappingPairs record whose embedded attribute
contains mapping-pairs runs without a terminator causes the function to
read past the slab allocation, triggering a KASAN slab-out-of-bounds
read on mount.

The sibling function run_unpack() received an analogous bounds-check in
commit b62567bca474 ("ntfs3: add buffer boundary checks to run_unpack()"),
but run_get_highest_vcn() was missed.

Take a run_buf_size parameter and reject any run header whose payload
would extend past the buffer end, mirroring the pattern used by
run_unpack().  The caller in fslog.c passes the remaining attribute
bytes after the mapping-pairs offset.

KASAN report (on mainline v7.1 merge window HEAD):

  BUG: KASAN: slab-out-of-bounds in run_get_highest_vcn+0x3c0/0x410
  Read of size 1 at addr ffff88800e2d5400 by task mount/72

This warning shows up with gcc-10 now:

The warning does look correct, as the 'out2' label can be reached
without initializing bmp_size and bmp_size_v. Initialize these at
the same place as bmp.

The faulting address sits 590 bytes inside a freed kmalloc-1k object
allocated by ni_add_subrecord() and freed from ni_write_inode()
writeback.

[CAUSE]
ntfs_readdir() loads all subrecords once, but then drops ni_lock()
before it starts walking the directory metadata through ntfs_read_hdr().
That leaves the current NTFS_DE pointer backed by parent-directory
subrecord memory that concurrent writeback is still allowed to compact
and free.

The later ntfs_dir_emit() -> ntfs_iget5() call exposes the stale e->ref,
but the lifetime bug starts earlier: readdir is still consuming
parent-directory metadata after releasing the lock that protects it.

[FIX]
Keep ni_lock() held from the point where ntfs_readdir() starts
consuming the directory metadata until the walk over root/index entries
is finished.

This closes the parent-directory lifetime hole directly and keeps the
existing readdir d_type behaviour unchanged.

overwriting system.dos_attrib on the same file.

 __x64_sys_write+0x77/0xc0 fs/read_write.c:746
 ...

[CAUSE]
system.ntfs_attrib updates ATTR_DATA flags via ni_new_attr_flags()
and switches i_mapping->a_ops to ntfs_aops_cmpr when
FILE_ATTRIBUTE_COMPRESSED is set. system.dos_attrib then overwrites
ni->std_fa from a one-byte DOS attribute value, clearing the compression
bit without updating ATTR_DATA or the mapping operations.

Old buffered writes use is_compressed(ni) to choose
__generic_file_write_iter(). That leaves generic_perform_write() calling
a NULL write_begin callback from ntfs_aops_cmpr.

[FIX]
Treat system.dos_attrib as a low-byte DOS attribute update and preserve the
existing non-DOS attribute bits in ni->std_fa. This keeps compressed and
sparse state consistent with ATTR_DATA and the mapping operations while
keeping the existing DOS attribute semantics intact.

A malformed NTFS directory index entry can advertise a key_size larger

[CAUSE]
The index-header validators only validated INDEX_HDR-level geometry.
They did not walk each NTFS_DE to verify entry alignment, subnode
layout, or that key_size fit inside the entry payload. They also
allowed a last sentinel entry to carry a non-zero key_size.

[FIX]
Walk every NTFS_DE in ntfs3's index-header validators and reject
entries with invalid layout, mismatched subnode state, oversized
key_size, or non-zero sentinel keys before lookup or log replay can
consume them.

Subject: [PATCH 2513/5214] fs/ntfs3: fix syncing wrong inode on DIRSYNC
 cross-directory rename

In ntfs3_rename(), when IS_DIRSYNC(new_dir) is true, the code syncs
the renamed file inode instead of the target directory new_dir:
    if (IS_DIRSYNC(new_dir))
        ntfs_sync_inode(inode);      /* should be new_dir */

DIRSYNC requires that directory metadata changes are written to disk
synchronously.  Since new_dir was modified (a new directory entry was
added), it is new_dir that must be synced to satisfy the guarantee,
not the renamed file itself.

This bug has existed since the initial ntfs3 implementation and was
carried through the refactoring in commit 78ab59fee07f
("fs/ntfs3: Rework file operations").

Fix by syncing new_dir instead of inode.

Fixes: 4342306f0f0d ("fs/ntfs3: Add file operations and implementation")

Subject: [PATCH 2514/5214] fs/ntfs3: validate Dirty Page Table capacity in
 log_replay copy_lcns

In the analysis pass of $LogFile journal replay, log_replay() copies
LCNs from each action log record into an existing Dirty Page Table
(DPT) entry without bounding the destination index. A crafted NTFS
image with DPT entry lcns_follow=1 and an action log record with
lcns_follow=2 produces a kernel slab out-of-bounds write at mount
time:

  BUG: KASAN: slab-out-of-bounds in log_replay+0x654c/0xdb60
  Write of size 8 at addr ffff8880095e1040 by task mount

Two attacker-controlled fields can drive j+i past the allocated
page_lcns[] array:

  1. dp->lcns_follow (capacity) can be smaller than lrh->lcns_follow.
  2. lrh->target_vcn may be smaller than dp->vcn, making the u64
     subtraction wrap to a huge size_t.

Validate target VCN delta and per-record LCN count against the
DPT entry capacity, bail via the existing out: cleanup label with
-EINVAL.

This mirrors the bounds-check pattern added in commit b2bc7c44ed17
("fs/ntfs3: Fix slab-out-of-bounds read in DeleteIndexEntryRoot")
and commit 0ca0485e4b2e ("fs/ntfs3: validate rec->used in
journal-replay file record check").

Subject: [PATCH 2515/5214] fs/ntfs3: fix wrong LCN in run_remove_range() when
 splitting a run

When run_remove_range() removes a middle portion of a non-sparse run,
it splits the run into head and tail parts.  The tail is inserted via
run_add_entry() but uses the original r->lcn as its starting LCN
instead of advancing it by the split offset.

For example, removing VCN range [10, 20) from a run
{vcn=0, lcn=100, len=30} should produce:
  {vcn=0,  lcn=100, len=10}   (head)
  {vcn=20, lcn=120, len=10}   (tail, lcn advanced by 20)

But the current code produces:
  {vcn=0,  lcn=100, len=10}
  {vcn=20, lcn=100, len=10}   (wrong: points to same physical clusters)

This creates overlapping physical mappings in the in-memory run tree,
which can corrupt cluster allocation decisions and lead to data
corruption.

The correct pattern is already used in run_insert_range():
  CLST lcn2 = r->lcn == SPARSE_LCN ? SPARSE_LCN : (r->lcn + len1);

Apply the same logic in run_remove_range().

Subject: [PATCH 2516/5214] fs/ntfs3: call _ntfs_bad_inode() when failing to
 rename

It is safe to call _ntfs_bad_inode on live inodes since:
  commit 519b078998ce ("fs/ntfs3: Exclude call make_bad_inode for live nodes.")

The WARN_ON was added when it wasn't safe by:
  commit d99208b91933 ("fs/ntfs3: cancle set bad inode after removing name fails")

Replace the WARN_ON with a call to _ntfs_bad_inode() to prevent further
operations on the inconsistent inode.

Subject: [PATCH 2518/5214] fs/ntfs3: zero stale pagecache beyond valid data
 length

Zero cached folios beyond the valid data length when closing a writable
mapping. This keeps cached data beyond initialized file contents zeroed
and prevents stale pagecache exposure after mmap-based writes.

Subject: [PATCH 2519/5214] fs/ntfs3: handle delayed allocation overlap in run
 lookup

Introduce run_lookup_entry_da() to look up data runs while taking
delayed allocation into account.

ntfs3 may have both committed extents and delayed allocation extents for
the same VCN range.  The new helper checks delayed allocation first and
falls back to the real run, then corrects the returned range when a real
run overlaps with a delayed allocation run.

writeback path and keeps the folio handling local to ntfs_writepages().

Subject: [PATCH 2521/5214] fs/ntfs3: force waiting for direct I/O completion

It makes ntfs3 wait for direct I/O completion before returning to the
caller, instead of allowing the write path to complete asynchronously.

The issue was discovered during internal tests.

Subject: [PATCH 2522/5214] fs/ntfs3: fold file size handling into
 ntfs_set_size()

Remove the separate ntfs_extend() and ntfs_truncate() helpers and route
file size changes through ntfs_set_size().

This consolidates ntfs3 size updates in one place and lets the write,
fallocate, and setattr paths share the same logic for updating i_size,
valid data length, and preallocated extents.

This patch fixes a few issues found during internal tests.

Subject: [PATCH 2523/5214] fs/ntfs3: reject SEEK_DATA and SEEK_HOLE past EOF
 early

Handle non-data/hole seeks through generic_file_llseek_size() and return
-ENXIO immediately when SEEK_DATA or SEEK_HOLE is requested at or past
EOF. Handle compressed files in such cases properly as well.

Subject: [PATCH 2525/5214] ntfs3: Allocate iomap inline_data using alloc_page

This fixes a BUG reported in iomap_write_end_inline:
iomap_inline_data_valid checks that the inline_data fits within
a page. If the inline_data is allocated with kmemdup there's no
guarantee that it's page-aligned, so the check sometimes fails.
Allocate it with alloc_page to ensure it's page-aligned.

Closes: https://bugzilla.kernel.org/show_bug.cgi?id=221446
Fixes: 099ef9ab9203 ("fs/ntfs3: implement iomap-based file operations")

The ntfs3 specific -Wmaybe-uninitialized flag found one more false-postive,
this time with gcc-10 on s390:

fs/ntfs3/frecord.c:1370:16: error: 'ins_attr' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Add an explicit NULL pointer check before using the pointer, and
initialize it to NULL.

Subject: [PATCH 2527/5214] fs/ntfs3: fix mount failure on 64K page-size
 kernels

On 64K page-size kernels, mounting NTFS volumes smaller than ~650 MB
fails with EINVAL. The issue is in log_replay(): the initial log page
size probe uses PAGE_SIZE (65536) instead of DefaultLogPageSize (4096)
when PAGE_SIZE exceeds DefaultLogPageSize * 2.

This makes norm_file_page() require the $LogFile to be at least
50 * 65536 = 3.2 MB, but mkfs.ntfs creates a $LogFile of only ~1.5 MB
for a typical 300 MB volume. norm_file_page() returns 0 and the mount
is rejected with EINVAL.

On 4K kernels the #if guard evaluates to true, so use_default=true is
passed and DefaultLogPageSize (4096) is used, requiring only ~200 KB.
This path works fine.

Fix this by always passing use_default=true, which forces the initial
probe to use DefaultLogPageSize regardless of the kernel's PAGE_SIZE.
This is safe because, after reading the on-disk restart area, log_replay()
already re-adjusts log->page_size to match the volume's actual
sys_page_size.

Also fix read_log_page() to pass log->page_size instead of PAGE_SIZE to
ntfs_fix_post_read(), matching the actual buffer size.

Subject: [PATCH 2528/5214] ntfs3: fix out-of-bounds read in ntfs_dir_emit()
 and hdr_find_e()

The bounds check in ntfs_dir_emit() compares fname->name_len (a
character count) against e->size (a byte count) without accounting
for the 2-byte-per-character UTF-16LE encoding or the ATTR_FILE_NAME
header size:

  if (fname->name_len + sizeof(struct NTFS_DE) > le16_to_cpu(e->size))

This computes: name_len + 16 > e_size

The correct check must account for the ATTR_FILE_NAME header (66 bytes
before the name) and the UTF-16LE character size (2 bytes each):

  sizeof(NTFS_DE) + offsetof(ATTR_FILE_NAME, name) +
  name_len * sizeof(short) > e_size

Which computes: 16 + 66 + name_len * 2 > e_size

The correct calculation already exists as fname_full_size() in ntfs.h
and is used in cmp_fnames(), namei.c, and fslog.c, but was not used
in the readdir path.

A crafted NTFS image with an index entry containing a small e->size
but large fname->name_len bypasses the current check, causing
ntfs_utf16_to_nls() to read past the entry boundary.

Additionally, add a key_size validation in hdr_find_e() to ensure the
declared key_size does not exceed the available entry data, preventing
comparison functions from reading past entry boundaries on the lookup
path.

Subject: [PATCH 2529/5214] KVM: x86: Take PIC lock on KVM_GET_IRQCHIP path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When userspace issues the KVM_SET_IRQCHIP ioctl to set the state of
the PIC, kvm_vm_ioctl_set_irqchip() grabs @kvm->arch.vpic->lock before
updating the state. However, the KVM_GET_IRQCHIP ioctl to retrieve the
same PIC state does not grab such lock, potentially causing torn reads
for userspace.

Fix this by grabbing the lock on the read path.

This issue goes all the way back. The bug was introduced with the
addition of PIC ioctl code itself in 6ceb9d791eee ("KVM: Add get/
set irqchip ioctls for in-kernel PIC live migration support"). Later,
894a9c5543ab ("KVM: x86: missing locking in PIT/IRQCHIP/SET_BSP_CPU
ioctl paths") added the locking for kvm_vm_ioctl_set_irqchip(), but
missed kvm_vm_ioctl_get_irqchip().

Avoid symlink-based pidfile clobbering by opening the pidfile with
O_NOFOLLOW and validating it with fstat() before locking/writing.

The daemon currently uses a fixed pidfile path under /tmp. A local
unprivileged user can pre-create a symlink at that path and cause a
root-run daemon instance to write into an attacker-chosen file.

find_format helper to filter the formats and only allow the proper
formats when setting or trying a capture format.

Subject: [PATCH 2538/5214] mm/damon: replace damon_rand() with a per-ctx
 lockless PRNG

damon_rand() on the sampling_addr hot path called get_random_u32_below(),
which takes a local_lock_irqsave() around a per-CPU batched entropy pool
and periodically refills it with ChaCha20.  At elevated nr_regions counts
(20k+), the lock_acquire / local_lock pair plus __get_random_u32_below()
dominate kdamond perf profiles.

Replace the helper with a lockless lfsr113 generator (struct rnd_state)
held per damon_ctx and seeded from get_random_u64() in damon_new_ctx().
kdamond is the single consumer of a given ctx, so no synchronization is
required.  Range mapping uses traditional reciprocal multiplication,
similar as get_random_u32_below(); for spans larger than U32_MAX (only
reachable on 64-bit) the slow path combines two u32 outputs and uses
mul_u64_u64_shr() at 64-bit width.  On 32-bit the slow path is dead code
and gets eliminated by the compiler.

The new helper takes a ctx parameter; damon_split_regions_of() and the
kunit tests that call it directly are updated accordingly.

lfsr113 is a linear PRNG and MUST NOT be used for anything
security-sensitive.  DAMON's sampling_addr is not exposed to userspace and
is only consumed as a probe point for PTE accessed-bit sampling, so a
non-cryptographic PRNG is appropriate here.

Tested with paddr monitoring and max_nr_regions=20000: kdamond CPU usage
reduced from ~72% to ~50% of one core.

Subject: [PATCH 2539/5214] proc/meminfo: expose per-node balloon pages in node
 meminfo

Commit 835de37603ef ("meminfo: add a per node counter for balloon
drivers") added NR_BALLOON_PAGES and exposed it in /proc/meminfo.
However, the per-node view at /sys/devices/system/node/nodeX/meminfo was
not updated, even though the counter is already tracked per-node.

Add it to node_read_meminfo() so users can see balloon usage per NUMA node
without having to parse the raw vmstat file.

Subject: [PATCH 2540/5214] mm/memory_hotplug: factor out altmap freeing checks

Use a small helper to centralize altmap freeing after verifying that all
vmemmap pages were released.  This keeps the check consistent between the
normal teardown path and the memory hotplug error paths.

Subject: [PATCH 2541/5214] selftests/mm: fix mmap() return value check in
 run_migration_benchmark

mmap() returns MAP_FAILED on error, not NULL.  The current check uses
!buffer->ptr, which evaluates to false when mmap() fails (since MAP_FAILED
is (void *)-1, not 0), so the error path is never taken.

Subject: [PATCH 2542/5214] sparc/mm: remove register_page_bootmem_info()

Patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)".

We want to remove CONFIG_HAVE_BOOTMEM_INFO_NODE.  As a first step, let's
limit the remaining harm to x86 and core code, removing sparc, ppc and
s390 leftovers, starting the stepwise removal by removing and simplifying
some code.

Once a related x86 vmemmap fix [1] is in, we can merge part 2 that will
remove CONFIG_HAVE_BOOTMEM_INFO_NODE entirely.

Tested on x86-64 with hugetlb vmemmap optimization in combination with
KMEMLEAK, making sure that the problem reported in dd0ff4d12dd2 ("bootmem:
remove the vmemmap pages from kmemleak in put_page_bootmem") does not
reappear -- hoping I managed to trigger the original problem.


This patch (of 8):

sparc does not select CONFIG_HAVE_BOOTMEM_INFO_NODE, therefore,
register_page_bootmem_info_node() is a nop.

Let's just get rid of register_page_bootmem_info().

In the past, we used to store the type in page->lru.next, introduced by
commit 5f24ce5fd34c ("thp: remove PG_buddy"). The location changed over
the years; ever since commit 0386aaa6e9c8 ("bootmem: stop using
page->index"), we store it alongside the info in page->private.

Consequently, there is no need to reset page->lru anymore.

Subject: [PATCH 2545/5214] mm/bootmem_info: remove call to
 kmemleak_free_part_phys()

The call to kmemleak_free_part_phys() was added in 2022 in
commit dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in
put_page_bootmem").

In 2025, commit b2aad24b5333 ("mm/memmap: prevent double scanning of memmap
by kmemleak") started to use MEMBLOCK_ALLOC_NOLEAKTRACE when allocating
the memmap to skip the kmemleak_alloc_phys() in the buddy.

So remove the call to kmemleak_free_part_phys(). If this would still
be required for other purposes, either free_reserved_page() should take
care of it, or selected users.

Subject: [PATCH 2546/5214] mm/bootmem_info: stop marking the pgdat as
 NODE_INFO

We removed the last user of NODE_INFO in commit 119c31caa59e ("mm/sparse:
remove !CONFIG_SPARSEMEM_VMEMMAP leftovers for CONFIG_MEMORY_HOTPLUG").

But it really was never used it besides for safety-checks ever since it was
introduced in commit 04753278769f ("memory hotplug: register section/node
id to free"), where we had the comment:

	5) The node information like pgdat has similar issues. But, this
	   will be able to be solved too by this.
	   (Not implemented yet, but, remembering node id in the pages.)

Of course, that never happened, and we are not planning on freeing the
node data (pgdat/pglist_data), during memory hotunplug.

So let's just stop marking the pgdat as NODE_INFO.

Subject: [PATCH 2547/5214] mm/bootmem_info: stop marking mem_section_usage as
 MIX_SECTION_INFO

We never free the ms->usage data for boot memory sections (see
section_deactivate()). And to identify whether ms->usage was allocated
from memblock, we simply identify it by looking at PG_reserved.

Consequently, there is no need to mark ms->usage as MIX_SECTION_INFO.
Let's just stop doing that.

Subject: [PATCH 2548/5214] s390/mm: use free_reserved_page() in
 vmem_free_pages()

We never select CONFIG_HAVE_BOOTMEM_INFO_NODE on s390. Therefore,
free_bootmem_page() nowadays always translates to free_reserved_page().

Let's use free_reserved_page() to replace the free_bootmem_page() loop.
We can stop including bootmem_info.h.

Likely, vmemmap freeing code could be factored out into the core in the
future.

register_page_bootmem_info_node() essentially only calls
register_page_bootmem_memmap(). However, on powerpc that function is a
nop. So there is not benefit in using CONFIG_HAVE_BOOTMEM_INFO_NODE
anymore, let's just drop it.

We can stop including bootmem_info.h.

Subject: [PATCH 2550/5214] selftests/mm: check file initialization writes in
 split_huge_page_test

create_pagecache_thp_and_fd() fills the backing file for the pagecache THP
tests using repeated write() calls, but the return value is never checked.

If a write fails or completes only partially, the test may continue with
an incompletely initialized file and produce misleading results.

Check the result of write() and fail the test if the expected number of
bytes was not written.

Subject: [PATCH 2551/5214] drivers/base/memory: make memory block get/put
 explicit

Rename the memory block lookup helper to make the acquired reference
explicit, add memory_block_put() to wrap put_device(), remove
find_memory_block(), and use memory_block_get() as the single block-id
based lookup interface.

This makes it clearer to callers that a successful lookup holds a
reference that must be dropped, reducing the chance of forgetting the
matching put and leaking the memory block device reference.

Subject: [PATCH 2552/5214] mm/damon/sysfs-schemes: fix double increment of
 nr_regions

damos_sysfs_populate_region_dir() increments sysfs_regions->nr_regions
twice when adding a new region: once explicitly before
kobject_init_and_add(), and once again through the post-increment used for
the kobject name.

As a result, nr_regions no longer matches the actual number of live
regions, and region directory names skip numbers (1, 3, 5, ...).

Use the already incremented value for naming instead of incrementing
nr_regions a second time.

Subject: [PATCH 2553/5214] mm/damon/lru_sort: validate min_region_size to be
 power of 2

Patch series "mm/damon: validate min_region_size to be power of 2", v5.

Problem
=======
When a user sets an invalid 'addr_unit' (e.g., 3) via DAMON_LRU_SORT or
DAMON_RECLAIM, 'min_region_sz' becomes a non-power-of-2 value. While
damon_commit_ctx() correctly detects this and returns -EINVAL, it sets
the 'maybe_corrupted' flag during this process.

This flag causes the running kdamond to terminate. While the termination
is a safety measure, it is suboptimal in this case because the error is
just a simple invalid input from the user, which shouldn't neccessitate
stopping the kdamond.

Solution
========
Add an early validation in damon_lru_sort_apply_parameters() and
damon_reclaim_apply_parameters() to check 'min_region_sz' before any
state change occurs. If it is non-power-of-2, return -EINVAL immediately,
preventing 'maybe_corrupted' from being set.

Patch 1 fixes the issue for DAMON_LRU_SORT.
Patch 2 fixes the issue for DAMON_RECLAIM.


This patch (of 2):

Problem
=======
When a user sets an invalid 'addr_unit' (e.g., 3) via DAMON_LRU_SORT,
'min_region_sz' becomes a non-power-of-2 value. While damon_commit_ctx()
correctly detects this and returns -EINVAL, it sets the
'maybe_corrupted' flag during this process.

This flag causes the running kdamond to terminate. While the termination
is a safety measure, it is suboptimal in this case because the error is
just a simple invalid input from the user, which shouldn't neccessitate
stopping the kdamond.

Reproduction
============
1. Enable DAMON_LRU_SORT
2. Set addr_unit=3
3. Commit inputs via 'commit_inputs'
4. Observe kdamond termination

Solution
========
Add an early validation in damon_lru_sort_apply_parameters() to check
'min_region_sz' before any state change occurs. If it is non-power-of-2,
return -EINVAL immediately, preventing 'maybe_corrupted' from being set.

Subject: [PATCH 2556/5214] mm/khugepaged: fix inconsistent MMF_VM_HUGEPAGE
 flag due to allocation failure order

__khugepaged_enter() sets MMF_VM_HUGEPAGE before allocating the
corresponding mm_slot.  If mm_slot_alloc() fails, the function returns
with the flag set but without inserting the mm into the khugepaged
tracking structures, leaving the mm in an inconsistent state where future
registration attempts are skipped.

Fix this by reordering: allocate the mm_slot first, then check and set the
flag.  If the flag is already set, free the allocated slot and return.
This ensures the flag is only set when the mm is successfully registered
in the khugepaged tracking structures.

Subject: [PATCH 2557/5214] mm/shrinker: avoid out-of-bounds read in
 set_shrinker_bit()

set_shrinker_bit() reads info->unit[shrinker_id_to_index(shrinker_id)]
before checking shrinker_id against info->map_nr_max, so an id past the
currently visible map_nr_max reads past the unit[] array before the
WARN_ON_ONCE() catches it.

Determined from code inspection.

Move the load into the bounded branch.

 mtree_insert_range() is inclusive

The kernel doc of mtree_insert_range() does not state if the address
represented by the "last" parameter is inclusive or exclusive.  This can
lead to bugs by code that assumes it is exclusive.  Explicitly state that
the parameter is inclusive.

Subject: [PATCH 2559/5214] mm/readahead: add kerneldoc for read_pages

Patch series "mm: document read_pages and simplify usage".

Add a kerneldoc for read_pages() to formalize an invariant and then use
it to simplify the callers in page_cache_ra_unbounded().


This patch (of 2):

Formalize one of the invariants provided by the current implementation so
that callers can depend on it, as discussed in [1].

Subject: [PATCH 2560/5214] mm/readahead: simplify page_cache_ra_unbounded loop
 counter reset

Minor cleanup, no behavior change intended.

`read_pages` ensures that `ractl->_nr_pages` is zero before it returns, so
the `ractl->_nr_pages` term in these expressions contributes nothing.
This seems to have been true since the statements were introduced in
commit f615bd5c4725f ("mm/readahead: Handle ractl nr_pages being
modified").

The new expression has an intuitive explanation.  When filesystems perform
readahead, they increment `ractl->_index` by the number of pages
processed, so, after `read_pages` returns, `ractl->_index` points to the
first page after those already processed.  `index` points to the first
page considered in the loop.  So, `ractl->_index - index` is the number of
pages processed by the loop so far.

Subject: [PATCH 2562/5214] selftests/mm: ksm-functional-tests: fix partial
 write handling

Update write() checks to properly detect and handle partial writes.

Previously, the write() calls used <= 0 to detect failure.  This condition
is never true for partial writes (ret > 0 but ret < len), so partial
writes were silently treated as success.

Fix this by verifying that write() returns the full expected length and
treating any mismatch as failure.

Subject: [PATCH 2564/5214] mm/hugetlb_cma: restrict hugetlb_cma parameter to
 gigantic-page alignment

Existing hugetlb_cma parameter handling logic rejects sizes smaller than
one gigantic page, but rounds up larger sizes that are not a multiple of
it.  The two behaviors are inconsistent and neither is documented.

To remove existing inconsistent and undefined behavior, restrict
hugetlb_cma parameter to only accept multiples of the gigantic page size.

After this restriction, the redundant round_up() in the allocation loop
can be removed.

The new restriction is also documented in kernel-parameters.txt.

Also, including other minor changes for readability improvement with no
functional change.

Subject: [PATCH 2565/5214] mm/mmu_notifier: fix a begin vs. start typo in the
 invalidate range comment

Fix a goof in the block comment for invalidate_range_{start,end}() where
start() is incorrectly referred to as begin().

No functional change intended.

Subject: [PATCH 2566/5214] mm/readahead: no PG_readahead on EOF

When readahead pulls in all the remaining pages for a file, setting the
readahead bit is counter productive.  The async readahead it would trigger
would almost certainly be a no-op.  Additionally, for mmap'd file IO, the
readahead bit limits the fault around [1], causing an extra minor fault
when the page is accessed.

This was discovered when looking at /sys/kernel/tracing/events/readahead
traces for a simple program.  With the patch applied, fewer
page_cache_ra_unbounded calls are observed.

[1] do_fault_around calls filemap_map_pages, which finds eligible pages
    by calling next_uptodate_folio [2]. next_uptodate_folio skips pages
    with PG_readahead set [3].

Subject: [PATCH 2567/5214] mm, swap: avoid leaving unused extend table after
 alloc race

Allocating an extend table requires dropping the ci lock first.  While the
lock is dropped, a concurrent put can decrease the slot's swap count to a
value that is no longer maxed out, so the extend table is no longer
required.  The current allocation path still attach the new extend table
to the cluster anyway, leaving it unused.

The next maxed out count on the same cluster may still reuse the table,
and frees it properly.  But swapoff could leak it indeed.

To eliminate the waste, re-check under the ci lock that the extend table
is still needed before publishing it, and free the local allocation
otherwise.

Also close the check window by ensuring every count decrement that brings
a slot below SWP_TB_COUNT_MAX - 1 runs swap_extend_table_try_free(), not
just the MAX to MAX - 1 transition.  With this, a freshly published extend
table that becomes redundant due to a racing put is freed on the very next
decrement, restoring the invariant that an empty cluster never has a
non-NULL ci->extend_table.

The added overhead is ignorable.

Subject: [PATCH 2569/5214] userfaultfd: ensure mremap_userfaultfd_fail()
 releases mmap_changing

Sashiko says:

  mremap_userfaultfd_prep() increments ctx->mmap_changing to stall
  concurrent operations, but mremap_userfaultfd_fail() does not
  decrement it before dropping the context reference.

If an mremap operation fails, ctx->mmap_changing remains elevated. This
will causes subsequent userfaultfd operations like a UFFDIO_COPY to fail
with -EAGAIN.

Decrement ctx->mmap_changing in mremap_userfaultfd_fail().

Subject: [PATCH 2571/5214] tools/mm/page-types: fix typo in madvise() error
 message

Patch series "tools/mm/page-types: Fix misc bugs".

This series fixes three issues in tools/mm/page-types.c:

1. Fix two typos in madvise() error messages ("madvice" -> "madvise")
2. Fix operator precedence bug in the sigbus handler where the ternary
   operator binds looser than addition, producing incorrect offset
   calculation when sigbus_addr is non-NULL
3. Fix --kpageflags option declaration in getopt_long: has_arg should
   be 1 (required_argument) since the option requires a file path


This patch (of 3):

Two error messages incorrectly spelled the madvise() function name as
"madvice".  Fix the typo in both occurrences.

Subject: [PATCH 2574/5214] mm/filemap: fix page_cache_prev_miss() when no hole
 is found

page_cache_prev_miss() is documented to return a value outside the
searched range when no gap is found.  However, the no-gap-found path
returns xas.xa_index, which after a successful loop is the first index in
the range.  As such, that index is misreported as a gap.

The sole caller, page_cache_sync_ra(), uses the return value to estimate
the cached run preceding a sequential read.  In some cases, the buggy
return value can undercount the contiguous range by one, shrinking the
readahead window or pushing borderline requests into the small-random-read
branch.

Fix this by returning the start of the range - 1 when no hole is found.
Update page_cache_next_miss() for clarity as well.

Both helpers were previously fixed together in commit 9425c591e06a ("page
cache: fix page_cache_next/prev_miss off by one"), but the fix was
reverted because it caused a hugetlb performance regression.  hugetlb no
longer uses these functions and next_miss was subsequently refixed in
commit 901a269ff3d5 ("filemap: fix page_cache_next_miss() when no hole
found") and commit bbcaee20e03e ("readahead: fix return value of
page_cache_next_miss() when no hole is found"), but prev_miss was not
addressed.

This was found by pointing Claude Opus 4.7 at mm/filemap.c.

Subject: [PATCH 2575/5214] mm: introduce for_each_free_list()

Patch series "mm: misc cleanups from __GFP_UNMAPPED series".

In v2 of the __GFP_UNMAPPED series [0], we realised that some of the
patches could potentially be merged as independent cleanups.

These are all independent of one another, if you think some are useful
cleanups and others are pointless churn, it should be fine to just pick
whatever subset you prefer.

No functional change intended.


This patch (of 4):

There are a couple of places that iterate over the freelists with
awareness of the data structures' layout.

It seems ideally, code outside of mm should not be aware of the page
allocator's freelists at all.  But, this patch just doesn't hide them
completely, it's just a meek incremental step in that direction: provide a
macro to iterate over it without needing to be aware of the actual struct
fields.

Subject: [PATCH 2576/5214] mm/page_alloc: don't overload migratetype in
 find_suitable_fallback()

This function currently returns a signed integer that encodes status
in-band, as negative numbers, along with a migratetype.  Switch to a more
explicit/verbose style that encodes the status and migratetype separately.

In the spirit of making things more explicit, also create an enum to avoid
using magic integer literals with special meanings.  This enables
documenting the values at their definition instead of in one of the
callers.

Subject: [PATCH 2577/5214] mm: rejig pageblock mask definitions

- Add a PAGEBLOCK_ prefix to the names to avoid polluting the "global
  namespace" too much.

- This new prefix makes MIGRATETYPE_AND_ISO_MASK look pretty long. Well,
  that global mask only exists for quite a specific purpose, and is
  quite a weird thing to have a name for anyway. So drop it and take
  advantage of the newly-defined PAGEBLOCK_ISO_MASK.

The ifdefs are not technically needed here, everything used here is
always defined.

Switching to IS_ENABLED() makes the code a bit less tiresome to read.

Subject: [PATCH 2579/5214] mm/page_alloc: drop a misleading __always_inline

get_pfnblock_migratetype() is called from outside page_alloc.c, so it
cannot always be inlined.  Remove the annotation to avoid misleading
readers.

At least in my minimal config, with GCC, this doesn't change
mm/page_alloc.o at all.

Subject: [PATCH 2580/5214] mm/page_alloc: document that alloc_pages_nolock()
 uses RCU

The allocator interacts with cgroups which rely on RCU.  RCU does not work
everywhere, so the "any context" claim is slightly overstated here.

This should already be enforced by objtool, since this function is not
marked noinstr the x86 build should fail if you call it from a place where
RCU is not watching.  But, expecting readers to make that connection for
themselves seems a bit cruel (I don't think there is even any
documentation of what noinstr means at all, let alone the connection with
RCU).

Note this is not claiming that any cgroup code called from the allocator
would actually break if this restriction was violated, it could very well
be that there's no real way for the allocator to act on a cgroup that can
disappear concurrently.  But, since it's likely nobody has verified this
one way or another, better to just be safe and declare that RCU is
required.  Allocating from an RCU-unsafe context seems a bit crazy anyway.

Subject: [PATCH 2581/5214] mm: swap_cgroup: fix NULL deref in
 lookup_swap_cgroup_id on swapless host

lookup_swap_cgroup_id() passes swap_cgroup_ctrl[type].map to
__swap_cgroup_id_lookup() without checking that the type was ever
registered via swap_cgroup_swapon().  On a swapless host every ctrl->map
is NULL, so __swap_cgroup_id_lookup() dereferences NULL + a scaled
swp_offset().

Since commit bea67dcc5eea ("mm: attempt to batch free swap entries for
zap_pte_range()"), zap_pte_range() -> swap_pte_batch() calls
lookup_swap_cgroup_id() on any non-present, non-none PTE that decodes as a
real swap entry, without first validating it against swap_info[].  A
single PTE corrupted into a type-0 swap entry takes the host down at
process exit.

We hit this in production on a swapless 6.12.58 host: ~1s of
"get_swap_device: Bad swap file entry 3f800204222bb" (do_swap_page() being
correctly defensive about the same entry) followed by

  BUG: unable to handle page fault for address: 000003f800204220
  RIP: 0010:lookup_swap_cgroup_id+0x2b/0x60
  Call Trace:
   swap_pte_batch+0xbf/0x230
   zap_pte_range+0x4c8/0x780
   unmap_page_range+0x190/0x3e0
   exit_mmap+0xd9/0x3c0
   do_exit+0x20c/0x4b0

syzbot has reported the identical stack.

The source of the PTE corruption is a separate bug; this change makes the
teardown path as robust as the fault path already is.  Every other caller
of lookup_swap_cgroup_id() is downstream of a get_swap_device() that has
already validated the entry, so the new branch is cold.

Subject: [PATCH 2582/5214] mm, swap: simplify swap cache allocation helper

Patch series "mm, swap: swap table phase IV: unify allocation", v5.

This series unifies the allocation and charging of anon and shmem swap in
folios, provides better synchronization, consolidates the metadata
management, hence dropping the static array and map, and improves the
performance.  The static metadata overhead is now close to zero, and
workload performance is slightly improved.

For example, mounting a 1TB swap device saves about 512MB of memory:

Before:
free -m
          total   used      free   shared   buff/cache   available
Mem:       1464    805       346        1          382         658
Swap:   1048575      0   1048575

After:
free -m
          total   used      free   shared   buff/cache   available
Mem:       1464    277       899         1         356        1187
Swap:   1048575      0   1048575

Memory usage is ~512M lower, and we now have a close to 0 static overhead.
It was about 2 bytes per slot before, now roughly 0.09375 bytes per slot
(48 bytes ci info per cluster, which is 512 slots).

Performance test is also looking good, testing Redis in a 2G VM using 6G
ZRAM as swap:

valkey-server --maxmemory 2560M
redis-benchmark -r 3000000 -n 3000000 -d 1024 -c 12 -P 32 -t get

Before: 3385017.283654 RPS
After:  3433309.307292 RPS (1.42% better)

Testing with build kernel under global pressure on a 48c96t system,
limiting the total memory to 8G, using 12G ZRAM, 24 test runs, enabling
THP:

make -j96, using defconfig

Before: user time 2904.59s system time 4773.99s
After:  user time 2909.38s system time 4641.55s (2.77% better)

Testing with usemem on a 32c machine using 48G brd ramdisk and 16G RAM, 12
test run:

usemem --init-time -O -y -x -n 48 1G

Before: Throughput (Sum): 6482.58 MB/s Free Latency: 371371.67us
After:  Throughput (Sum): 6539.28 MB/s Free Latency: 363059.88us

Seems similar, or slightly better.

This series also reduces memory thrashing, I no longer see any: "Huh
VM_FAULT_OOM leaked out to the #PF handler.  Retrying PF", it was shown
several times during stress testing before this series when under great
pressure:

Before: grep -Ri VM_FAULT_OOM <test logs> | wc -l => 18
After:  grep -Ri VM_FAULT_OOM <test logs> | wc -l => 0


This patch (of 12):

Instead of trying to return the existing folio if the entry is already
cached in swap_cache_alloc_folio, simply return an error pointer if the
allocation failed, and drop the output argument that indicates what kind
of folio is actually returned.

And a proper wrapper swap_cache_read_folio that decouples and handles the
actual requirement - read in the folio, or return the already read folio
in cache.  This is what async swapin and readahead actually required.

As for zswap swap out, the caller just needs to abort if the allocation
fails because the entry is gone or already cached, so removing simplifies
the return argument, making it cleaner.

No feature change.

Subject: [PATCH 2583/5214] mm, swap: move common swap cache operations into
 standalone helpers

Move a few swap cache checking, adding, and deletion operations into
standalone helpers to be used later.  And while at it, add proper kernel
doc.

No feature or behavior change.

Subject: [PATCH 2584/5214] mm/huge_memory: move THP gfp limit helper into
 header

Shmem has some special requirements for THP GFP and has to limit it in
certain zones or provide a more lenient fallback.

We'll use this helper for generic swap THP allocation, which needs to
support shmem.  For a typical GFP_HIGHUSER_MOVABLE swap-in, this helper is
basically a no-op.  But it's necessary for certain shmem users, mostly
drivers.

No feature change.

Subject: [PATCH 2585/5214] mm, swap: add support for stable large allocation
 in swap cache directly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To make it possible to allocate large folios directly in swap cache,
provide a new infrastructure helper to handle the swap cache status check,
allocation, and order fallback in the swap cache layer

The new helper replaces the existing swap_cache_alloc_folio.  Based on
this, all the separate swap folio allocation that is being done by anon /
shmem before is converted to use this helper directly, unifying folio
allocation for anon, shmem, and readahead.

This slightly consolidates how allocation is synchronized, making it more
stable and less prone to errors.  The slot-count and cache-conflict check
is now always performed with the cluster lock held before allocation, and
repeated under the same lock right before cache insertion.  This double
check produces a stable result compared to the previous anon and shmem
mTHP allocation implementation, avoids the false-negative conflict checks
that the lockless path can return — large allocations no longer have to
be unwound because the range turned out to be occupied — and aborts
early for already-freed slots, which helps ordinary swapin and especially
readahead, with only a marginal increase in cluster-lock contention (the
lock is very lightly contended and stays local in the first place).
Hence, callers of swap_cache_alloc_folio() no longer need to check the
swap slot count or swap cache status themselves.

And now whoever first successfully allocates a folio in the swap cache
will be the one who charges it and performs the swap-in.  The race window
of swapping is also reduced since the loop is much more compact.

Subject: [PATCH 2586/5214] mm, swap: unify large folio allocation

Now that direct large order allocation is supported in the swap cache,
both anon and shmem can use it instead of implementing their own methods.
This unifies the fallback and swap cache check, which also reduces the
TOCTOU race window of swap cache state: previously, high order swapin
required checking swap cache states first, then allocating and falling
back separately.  Now all these steps happen in the same compact loop.

Order fallback and statistics are also unified, callers just need to check
and pass the acceptable order bitmask.

There is basically no behavior change.  This only makes things more
unified and prepares for later commits.  Cgroup and zero map checks can
also be moved into the compact loop, further reducing race windows and
redundancy

Date: Sun, 17 May 2026 23:39:45 +0800
Subject: [PATCH 2587/5214] mm/memcg, swap: tidy up cgroup v1 memsw swap
 helpers

The cgroup v1 swap helpers always operate on swap cache folios whose swap
entry is stable: the folio is locked and in the swap cache.  There is no
need to pass the swap entry or page count as separate parameters when they
can be derived from the folio itself.

Simplify the redundant parameters and add sanity checks to document the
required preconditions.

Also rename memcg1_swapout to __memcg1_swapout to indicate it requires
special calling context: the folio must be isolated and dying, and the
call must be made with interrupts disabled.

No functional change.

Subject: [PATCH 2588/5214] mm, swap: support flexible batch freeing of slots
 in different memcgs

Instead of requiring the caller to ensure all slots are in the same memcg,
make the function handle different memcgs at once.

This is both a micro optimization and required for removing the memcg
lookup in the page table layer, so it can be unified at the swap layer.

We are not removing the memcg lookup in the page table in this commit.  It
has to be done after the memcg lookup is deferred to the swap layer.

Subject: [PATCH 2589/5214] mm, swap: delay and unify memcg lookup and charging
 for swapin

Instead of checking the cgroup private ID during page table walk in
swap_pte_batch(), move the memcg lookup into __swap_cache_add_check()
under the cluster lock.

The first pre-alloc check is speculative and skips the memcg check since
the post-alloc stable check ensures all slots covered by the folio belong
to the same memcg.  It is very rare for contiguous and aligned entries
across a contiguous region of a page table of the same process or shmem
mapping to belong to different memcgs.

This also prepares for recording the memcg info in the cluster's table.
Also make the order check and fallback more compact.

There should be no user-observable behavior change.

Subject: [PATCH 2590/5214] mm, swap: consolidate cluster allocation helpers

Swap cluster table management is spread across several narrow helpers.  As
a result, the allocation and fallback sequences are open-coded in multiple
places.

A few more per-cluster tables will be added soon, so avoid duplicating
these sequences per table type.  Fold the existing pairs into
cluster-oriented helpers, and rename for consistency.

No functional change, only a few sanity checks are slightly adjusted.

Subject: [PATCH 2591/5214] mm/memcg, swap: store cgroup id in cluster table
 directly

Drop the usage of the swap_cgroup_ctrl, and use the dynamic cluster table
instead.

The per-cluster memcg table is 1024 / 512 bytes on most archs, and does
not need RCU protection: the cgroup data is only read and written under
the cluster lock.  That keeps things simple, lets the allocation use plain
kmalloc with immediate kfree (no deferred free), and keeps fragmentation
acceptable.

Subject: [PATCH 2592/5214] mm/memcg: remove no longer used swap cgroup array

Now all swap cgroup records are stored in the swap cluster directly, the
static array is no longer needed.

Subject: [PATCH 2593/5214] mm, swap: merge zeromap into swap table

By allocating one additional bit in the swap table entry's flags field
alongside the count, we can store the zeromap inline

For 64 bit systems, zeromap will store in the swap table, avoiding zeromap
allocation.  It reduces the allocated memory.  That is the happy path.

For certain 32-bit archs, there might not be enough bits in the swap table
to contain both PFN and flags.  Therefore, conditionally let each cluster
have a zeromap field at build time, and use that instead.  If the swapfile
cluster is not fully used, it will still save memory for zeromap.  The
empty cluster does not allocate a zeromap.  In the worst case, all cluster
are fully populated.  We will use memory similar to the previous zeromap
implementation.

A few macros were moved to different headers for build time struct
definition.

Subject: [PATCH 2597/5214] mm/damon/core: introduce struct damon_probe

Patch series "mm/damon: introduce data attributes monitoring".

TL; DR
======

Extend DAMON for monitoring general data attributes other than accesses.
The short term motivation is lightweight page type (e.g., belonging
cgroup) aware monitoring.  In long term, this will help extending DAMON
for multiple access events capture primitives (e.g., page faults and PMU)
and eventually pivotting DAMON to a "Data Attributes Monitoring and
Operations eNgine" in long term.

Background: High Cost of Page Level Properties Monitoring
=========================================================

DAMON is initially introduced as a Data Access MONitor.  It has been
extended for not only access monitoring but also data access-aware system
operations (DAMOS).  But still the monitoring part is only for data
accesses.

Data access patterns is good information, but some users need more
holistic views.  Particularly, users want to show the access pattern
information together with the types of the memory.  For example, users who
work for making huge pages efficiently want to know how much of
DAMON-found hot/cold regions are backed by huge pages.  Users who run
multiple workloads with different cgroups want to know how much of
DAMON-found hot/cold regions belong to specific cgroups.

For the user demand, we developed a DAMOS extension for page level
properties based monitoring [1], which has landed on 6.14.  Using the
feature, users can inform the page level data properties that they are
interested in, in a flexible format that uses DAMOS filters.  Then, DAMON
applies the filters to each folio of the entire DAMON region and lets
users know how many bytes of memory in each DAMON region passed the given
filters.

This gives page level detailed and deterministic information to users.
But, because the operation is done at page level, the overhead is
proportional to the memory size.  It was useful for test or debugging
purposes on a small number of machines.  But it was obviously too heavy to
be enabled always on all machines running the real user workloads.  For
real world workloads, it was recommended to use the feature with
user-space controlled sampling approaches.  For example, users could do
the page level monitoring only once per hour, on randomly selected one
percent of machines of their fleet.  If the runtime and the size of the
fleet is long and big enough, it should provide statistically meaningful
data.

But users are too busy to implement such controls on their own.

Data Attributes Monitoring
==========================

Extend DAMON to monitor not only data accesses, but also general data
attributes.  Do the extension while keeping the main promise of DAMON, the
bounded and best-effort minimum overhead.

Allow users to specify what data attributes in addition to the data access
they want to monitor.  Users can install one 'data probe' per data
attribute of their interest for this purpose.  The 'data probe' should be
able to be applied to any memory, and determine if the given memory has
the appropriate data attribute.  E.g., if memory of physical address 42
belongs to cgroup A.  Each 'data probe' is configured with filters that
are very similar to the DAMOS filters.

When DAMON checks if each sampling address memory of each region is
accessed since the last check, it applies data probes if registered.  Same
to the number of access check-positive samples accounting (nr_accesses),
it accounts the number of each data probe-positive samples in another
per-region counters array, namely 'probe_hits'.  When DAMON resets
nr_accesses every aggregation interval, it resets 'probe_hits' together.

Users can read 'probe_hits' just before the values are reset.  In this
way, users can know how many hot/cold memory regions have data attributes
of their interest.  E.g., 30 percent of this system's hot memory is
belonging to cgroup A, and 80 percent of the cgroup A-belonging hot memory
is backed by huge pages.

Patches Sequence
================

First eight patches implement the core feature, interface and the working
support.  Patch 1 introduces data probe data structure, namely
damon_probe.  Patch 2 extends damon_ctx for installing data probes.  Patch
3 introduces another data structure for filters of each data probe, namely
damon_filter.  Patch 4 updates damon_ctx commit function to handle the
probes.  Patch 5 extends damon_region for the per-region per-probe
positive samples counter, namely probe_hits.  Patch 6 extends
damon_operations for applying probes on the underlying DAMON operations
implementation.  Patch 7 updates kdamond_fn() to invoke the probes
applying callback.  Patch 8 finally implements the probes support on paddr
ops.

Ten changes for user interface (patches 9-18) come next.  Patches 9-13
implements sysfs directories and files for setting data probes, namely
probes directory, probe directory, filters directory, filter directory and
filter directory internal files, respectively.  Patch 14 connects the user
inputs that are made via the sysfs files to DAMON core.  Following three
patches (patches 15-17) implement sysfs directories and files for showing
the probe_hits to users, namely probes directory, probe directory and hits
files, respectively.  Patch 18 introduces a new tracepoint for showing the
probe_hits via tracefs.

Patch 19 adds a selftest for the sysfs files.

Patches 20 and 21 documents the design and usage of the new feature,
respectively.

Seven additional patches (patches 22-28) for monitoring belonging memory
cgroup follow.  Depending on the feedback, this part might be separated to
another series in future.  Patch 22 defines the DAMON filter type for the
new attribute, namely DAMON_FILTER_TYPE_MEMCG.  Patch 23 add the support
on paddr ops.  Patch 24 updates the sysfs interface for setup of the
target memcg.  Patch 25 move code for easy reuse of the filter target
memcg setup.  Patch 26 connects the user input to the core layer.
Finally, patches 27 and 28 update the design and usage documents for the
memcg attribute monitoring support.

Discussion
==========

This allows the page properties monitoring with overhead that is low
enough to be enabled always on real world workloads.  Because the sampling
time for access check is reused for data attributes check, the
upper-bounded and best-effort minimum overhead of DAMON is kept.  Because
the sampling memory for access check is reused for data attributes check,
additional overhead is minimum.

Still DAMOS-based page level properties monitoring should be useful,
because it provides a deterministic page level information.  When in doubt
of the sampling based information, running DAMOS-based one together and
comparing the results would be useful, for debugging and tuning.

Future Works: Mid Term
========================

This version of implementation is limiting the maximum number of data
probes to four.  I will try to find a way to remove the limit in future.
I personally think it should be enough for common use cases, though, and
therefore not giving high priority at the moment.

Future Works: Long Term
=======================

There are user requests for extending DAMON with detailed access
information, for example, per-CPUs/threads/read/writes monitoring.  For
that, I was working [2] on extending DAMON to use page fault events as
another access check primitives, and making the infrastructure flexible
for future use of yet another access check primitive.  Actually there is
another ongoing work [3] for extending DAMON with PMU events.  The
motivation of the work is reducing the overhead, though.

In my work [2], I was introducing a new interface for access sampling
primitives control.  Now I think this data probe interface can be used for
that, too.  That is, data access becomes just one type of data attribute.
Also, pg_idle-confirmed access, page fault-confirmed access, and PMU
event-confirmed access will be different types of data attributes.

The regions adjustment mechanism is currently working based on the access
information.  That's because DAMON is designed for data access monitoring.
That is, data access information is the primary interest, and therefore
DAMON adjusts regions in a way that can best-present the information.

Once data access becomes just one of data attributes, there is no reason
to think data access that special.  There might be some users not
interested in access at all but want to know the location of memory of
specific type.  Data probes interface will allow doing that.  Further, we
could extend the interface to let users set any data attribute as the
'primary' attribute.  Then, DAMON will split and merge regions in a way
that can best-present the 'primary' attributes.

DAMOS will also be extended, to specify targets based on not only the data
access pattern, but all user-registered data attributes.  From this stage,
we may be able to call DAMON as a "Data Attributes Monitoring and
Operations eNgine".


This patch (of 28):

Introduce a data structure for data attribute probe.  It is just a linked
list header at this step.  It will be extended in a way that it can
determine if a given memory has a specific data attribute.

Subject: [PATCH 2599/5214] mm/damon/core: introduce damon_filter

Define a data structure for constructing damon_probe's attributes check,
namely damon_filter.  It is very similar to damos_filter but works only
for monitoring purposes.  Also embed that into damon_probe, implement
essential handling of the link, with fundamental helpers.

Extend damon_operations struct with a new callback, namely apply_probes.
The callback will be invoked for data attributes monitoring.  More
specifically, the callback will apply damon_probe objects to each region
and update the per-region per-probe counters for the number of encountered
probe-positive samples.

 (``nr_accesses``) has significantly changed.  If so, the counter is reset to
 zero.  Otherwise, the counter is increased.
 
+Data Attributes Monitoring
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Data access pattern is only one type of data attributes.  In some use cases,
+users need to know more data attributes information.  For example, users may
+need to know how much of a given hot or cold memory region is backed by
+anonymous pages, or belong to a specific cgroup.  For such use case, data
+attributes monitoring feature is provided.
+
+Using the feature, users can register data attributes of their interest to the
+DAMON :ref:`context <damon_design_execution_model_and_data_structures>`.  The
+registration is made by specifying a probe per attribute.  Each of the probe
+specifies a rule to determine if a given memory region has the related
+attribute.  The rule is constructed with multiple filters.  The filters work
+same to :ref:`DAMOS filters <damon_design_damos_filters>` except the supported
+filter types.  Currently only ``anon`` filter type is supported for data
+attributes monitoring.
+
+If such probes are registered, DAMON executes the probes for each region's
+sampling memory when it does the access :ref:`sampling
+<damon_design_region_based_sampling>`.  The number of samples that identified
+as having the data attribute (hitting the probe) per :ref:`aggregation interval
+<damon_design_monitoring>` is accounted in a per-region per-probe counter.
+Users can therefore know how much of a given DAMON region has a specific data
+attribute by reading the per-region per-probe probe hits counter after each
+aggregation interval.
+
+This is a sampling based mechanism.  Hence, it is lightweight but the output
+may include some measurement errors.  The output should be used with good
+understanding of statistics.
+
+Another way to do this for higher accuracy is using :ref:`DAMOS filter
+<damon_design_damos_filters>` with ``stat`` :ref:`action
+<damon_design_damos_action>` and ``sz_ops_filter_passed`` :ref:`stat
+<damon_design_damos_stat>`.  This approach provides the data attributes
+information in page level.  But, because it is operated in page level, the
+overhead is proportional to the size of the memory.

Introduce a new DAMON sysfs file for letting users setup the target memory
cgroup of the belonging memory cgroup attribute monitoring.  The file is
named 'path', located under the probe filter directory.  Users can set the
target memory cgroup by writing the path to the memory cgroup from the
cgroup mount point to the file.

Subject: [PATCH 2621/5214] mm/damon/sysfs-schemes: move memcg_path_to_id() to
 sysfs-common

The next commit will need to find the memcg id from the user-passed path
to the memory cgroup, from sysfs.c.  memcg_path_to_id() is doing that, but
defined in sysfs-schemes.c as a static function.  Move the function to
sysfs-common.c and mark it as non-static, so that the next commit can
reuse the function.

Subject: [PATCH 2625/5214] mm/vmalloc: extract vm_area_free_pages() helper
 from vfree()

Patch series "mm/vmalloc: free unused pages on vrealloc() shrink", v14.

This series implements the TODO in vrealloc() to unmap and free unused
pages when shrinking across a page boundary.

Problem:
When vrealloc() shrinks an allocation, it updates bookkeeping
(requested_size, KASAN shadow) but does not free the underlying physical
pages. This wastes memory for the lifetime of the allocation.

Solution:
- Patch 1: Extracts a vm_area_free_pages(vm, start_idx, end_idx) helper
  from vfree() that frees a range of pages with memcg and nr_vmalloc_pages
  accounting. Freed page pointers are set to NULL to prevent stale
  references.
- Patch 2: Update the grow-in-place check in vrealloc() to compare the
  requested size against the actual physical page count (vm->nr_pages)
  rather than the virtual area sizes. This is a prerequisite for shrinking.
- Patch 3: For VM_ALLOC areas in vread_iter(), derive the vm area size
  from vm->nr_pages rather than get_vm_area_size(), which would
  overestimate the mapped range after a shrink. Other mapping types
  (vmap, ioremap) don't set nr_pages and keep using get_vm_area_size().
- Patch 4: Uses the helper to free tail pages when vrealloc() shrinks
  across a page boundary.
- Patch 5: Adds a vrealloc test case to lib/test_vmalloc that exercises
  grow-realloc, shrink-across-boundary, shrink-within-page, and
  grow-in-place paths.

The virtual address reservation is kept intact to preserve the range for
potential future grow-in-place support.  A concrete user is the Rust
binder driver's KVVec::shrink_to [1], which performs explicit vrealloc()
shrinks for memory reclamation.


This patch (of 5):

Extract page freeing and NR_VMALLOC stat accounting from vfree() into a
reusable vm_area_free_pages() helper.  The helper operates on a range
[start_idx, end_idx) of pages from a vm_struct, making it suitable for
both full free (vfree) and partial free (upcoming vrealloc shrink).

Freed page pointers in vm->pages[] are set to NULL to prevent stale
references when the vm_struct outlives the free (as in vrealloc shrink).

Subject: [PATCH 2626/5214] mm/vmalloc: use physical page count for vrealloc()
 grow-in-place check

Update the grow-in-place check in vrealloc() to compare the requested size
against the actual physical page count (vm->nr_pages) rather than the
virtual area size (alloced_size, derived from get_vm_area_size()).

Currently both values are equivalent, but the upcoming vrealloc() shrink
functionality will free pages without reducing the virtual reservation
size.  After such a shrink, the old alloced_size-based comparison would
incorrectly allow a grow-in-place operation to succeed and attempt to
access freed pages.  Switch to vm->nr_pages now so the check remains
correct once shrink support is added.

Subject: [PATCH 2628/5214] mm/vmalloc: free unused pages on vrealloc() shrink

When vrealloc() shrinks an allocation and the new size crosses a page
boundary, unmap and free the tail pages that are no longer needed.  This
reclaims physical memory that was previously wasted for the lifetime of
the allocation.

The heuristic is simple: always free when at least one full page becomes
unused.  Huge page allocations (page_order > 0) are skipped, as partial
freeing would require splitting.  Allocations with VM_FLUSH_RESET_PERMS
are also skipped, as their direct-map permissions must be reset before
pages are returned to the page allocator, which is handled by
vm_reset_perms() during vfree().

Additionally, allocations with VM_USERMAP are skipped because
remap_vmalloc_range_partial() validates mapping requests against the
unchanged vm->size; freeing tail pages would cause vmalloc_to_page() to
return NULL for the unmapped range.

To protect concurrent readers, the shrink path uses Node lock to
synchronize before freeing the pages.

Finally, we notify kmemleak of the reduced allocation size using
kmemleak_free_part() to prevent the kmemleak scanner from faulting on the
newly unmapped virtual addresses.

The virtual address reservation (vm->size / vmap_area) is intentionally
kept unchanged, preserving the address for potential future grow-in-place
support.

Subject: [PATCH 2629/5214] lib/test_vmalloc: add vrealloc test case

Introduce a new test case "vrealloc_test" that exercises the vrealloc()
shrink and in-place grow paths:

  - Grow beyond allocated pages (triggers full reallocation).
  - Shrink crossing a page boundary (frees tail pages).
  - Shrink within the same page (no page freeing).
  - Grow within the already allocated page count (in-place).

Data integrity is validated after each realloc step by checking that the
first byte of the original allocation is preserved.

Subject: [PATCH 2630/5214] drivers/base/memory: set mem->altmap after
 successful device registration

If __add_memory_block() fails at xa_store() (under memory pressure for
example), device_unregister() is called, which eventually triggers
memory_block_release() with mem->altmap still set, causing a
WARN_ON(mem->altmap).  This was triggered by modifying virtio-mem driver.

Fix this by delaying the assignment of mem->altmap until after
__add_memory_block() has succeeded.

Subject: [PATCH 2631/5214] mm/memory-failure: use zone_pcp_disable() for
 poison handling

__page_handle_poison() used drain_all_pages() instead of
zone_pcp_disable() because dissolve_free_hugetlb_folio() could restore HVO
vmemmap pages and decrement hugetlb_optimize_vmemmap_key.  That static key
update took cpu_hotplug_lock through static_key_slow_dec(), while
zone_pcp_disable() holds pcp_batch_high_lock.  CPU hotplug takes the locks
in the opposite order through page_alloc_cpu_online/dead(), so the
combination could deadlock.

That dependency no longer exists.  Commit da3e2d1ca43d ("mm/hugetlb:
remove hugetlb_optimize_vmemmap_key static key") removed the HVO static
key and the static_branch_dec() from hugetlb_vmemmap_restore_folio().  The
dissolve_free_hugetlb_folio() path no longer reaches
static_key_slow_dec().

Use zone_pcp_disable() again while dissolving the hugetlb folio and taking
the target page off the buddy allocator.  This prevents the drained PCP
lists from being refilled before take_page_off_buddy() runs, making the
page isolation deterministic.

Subject: [PATCH 2632/5214] mm/damon/vaddr: attempt per-vma lock during page
 table walk

Currently, DAMON virtual address operations use mmap_read_lock during page
table walks, which can cause unnecessary contention under high
concurrency.

Introduce damon_va_walk_page_range() to first attempt acquiring a per-vma
lock.  If the VMA is found and the range is fully contained within it, the
page table walk proceeds with the per-vma lock instead of mmap_read_lock.

This optimization is expected to be particularly effective for
damon_va_young() and damon_va_mkold(), which are frequently called and
typically operate within a single VMA.

Patch series "mm/damon: documentation and comment fixes".


This patch (of 3):

damon_set_attrs() updates next_aggregation_sis and next_ops_update_sis for
online attrs updates, but it does not update next_intervals_tune_sis
there.

This can look like a missing update when reading damon_set_attrs() alone,
while next_intervals_tune_sis is actually updated in kdamond_fn().

Add a short comment to make this explicit.

Subject: [PATCH 2636/5214] Docs/{ABI,admin-guide}/damon: fix various typoes

``damon_target_idx`` was wrongly written as ``target_idx`` in the docs.
Fix it all over the place, as well as the wrong directory count, grammar,
etc.

Subject: [PATCH 2641/5214] pmdomain: sunxi: support power domain flags for
 pck600

While bringing up the PowerVR GPU on the A733 (Radxa Cubie A7Z), we
found that one of the GPU power domains must be configured as "always
on." While the Radxa BSP device tree leaves the GPU power domain nodes
commented out, the GPU driver code contains traces indicating an "always
on" requirement [1].

Currently, sunxi_pck600_desc only supports specifying pd_names. This
patch introduces sunxi_pck600_pd_desc, which stores both the name and
its associated flags. This also (more or less) aligns the implementation
with the existing sun50i PPU handling of always-on domains.

With this change, individual power domains can now be configured more
granularly. In particular, the GPU_CORE domain in sun60i_a733_pck600_pds
can now be explicitly marked with GENPD_FLAG_ALWAYS_ON.

The patch was tested on the Radxa Cubie A7Z, where the GPU now functions
as expected.

Thanks to Icenowy for her support and expertise on sunxi and PowerVR,
and thanks to Mikhail for identifying this exact cause of the GPU
bring-up issue.

Subject: [PATCH 2646/5214] iio: light: tsl2591: remove unneeded
 tsl2591_compatible_als_persist_cycle()

The function was only used to verify if als_persist is a
TSL2591_PRST_ALS_INT_CYCLE_* value. However, before its call in
tsl2591_write_event_value(), the line
als_persist = tsl2591_persist_lit_to_cycle(period) is executed,
meaning that by the time tsl2591_compatible_als_persist_cycle()
is reached, als_persist is a TSL2591_PRST_ALS_INT_CYCLE_* value,
making the verification pointless.

Subject: [PATCH 2647/5214] ipmi: fix refcount leak in i_ipmi_request()

When a caller provides a `supplied_recv` message to i_ipmi_request(),
the function increments the user's `nr_msgs` reference count. If an
error occurs later, the out_err cleanup path only frees the recv_msg
if the function allocated it itself (i.e., !supplied_recv). In the
supplied_recv case the cleanup is skipped, leaving the reference count
elevated. The caller ipmi_request_supply_msgs() does not release the
supplied_recv on error, so the reference is permanently leaked.

Fix this by explicitly reverting the reference count operations when a
supplied recv_msg with a valid user pointer is present in the error
path: decrement nr_msgs and drop the user's kref.

Subject: [PATCH 2648/5214] KVM: SVM: Truncate INVLPGA address in compatibility
 mode

Check for full 64-bit mode, not just long mode, when truncating the
virtual address as part of INVLPGA emulation.  Compatibility mode doesn't
support 64-bit addressing.

Note, the FIXME still applies, e.g. if the guest deliberately targeted
EAX while in 64-bit via an address size override.  That flaw isn't worth
fixing as it would require decoding the code stream, which would open an
entirely different can of worms, and in practice no sane guest would shove
garbage into RAX[63:32] and execute INVLPGA.

Note #2, VMSAVE, VMLOAD, and VMRUN all suffer from the same architectural
flaw of not providing the full linear address in a VMCB exit information
field, because, quoting the APM verbatim:

  the linear address is available directly from the guest rAX register

(VMSAVE, VMLOAD, and VMRUN take a physical address, but their behavior
with respect to rAX is otherwise identical).

Subject: [PATCH 2651/5214] KVM: VMX: Read 32-bit GPR values for ENCLS
 instructions outside of 64-bit mode

When getting register values for ENCLS emulation, use kvm_register_read()
instead of kvm_<reg>_read() so that bits 63:32 of the register are dropped
if the guest is in 32-bit mode.

Note, the misleading/surprising behavior of kvm_<reg>_read() being "raw"
variants under the hood will be addressed once all non-benign bugs are
fixed.

Fixes: 70210c044b4e ("KVM: VMX: Add SGX ENCLS[ECREATE] handler to enforce CPUID restrictions")
Fixes: b6f084ca5538 ("KVM: VMX: Add ENCLS[EINIT] handler to support SGX Launch Control (LC)")

 truncating values for 32-bit

When tracing hypercalls, invoke the tracepoint *after* truncating the
register values for 32-bit guests so as not to record unused garbage (in
the extremely unlikely scenario that the guest left garbage in a register
after transitioning from 64-bit mode to 32-bit mode).

Subject: [PATCH 2653/5214] KVM: x86: Rename kvm_cache_regs.h => regs.h

Rename kvm_cache_regs.h to simply regs.h, as the "cache" nomenclature is
already a lie (the file deals with state/registers that aren't cached per
se), and so that more code/functionality can be landed in the header
without making it a truly horrible misnomer.

Deliberately drop the kvm_ prefix/namespace to align with other "local"
headers, and to further differentiate regs.h from the public/global
arch/x86/include/asm/kvm_vcpu_regs.h, which sadly needs to stay in asm/
so that the number of registers can be referenced by kvm_vcpu_arch.

No functional change intended.

Subject: [PATCH 2654/5214] KVM: x86: Move inlined GPR, CR, and DR helpers from
 x86.h to regs.h

Move inlined General Purpose Register, Control Register, and Debug
Register helpers from x86.h to the aptly named regs.h, to help trim
down x86.h (and x86.c in the future).

Move *very* select EFER functionality as well, but leave behind the bulk of
EFER handling and all other MSR handling.  There is more than enough MSR
code to carve out msrs.{c,h} in the future.  Give is_long_bit_mode()
special treatment as it's more along the lines of a CR4 bit check, but just
happens to be accessed through an MSR interface.  And more importantly,
because giving regs.h access to is_long_bit_mode() greatly simplifies
dependency chains.

No functional change intended.

Subject: [PATCH 2655/5214] KVM: x86: Add mode-aware versions of
 kvm_<reg>_{read,write}() helpers

Make kvm_<reg>_{read,write}() mode-aware (where the value is truncated to
32 bits if the vCPU isn't in 64-bit mode), and convert all the intentional
"raw" accesses to kvm_<reg>_{read,write}_raw() versions.  To avoid
confusion and bikeshedding over whether or not explicit 32-bit accesses
should use the "raw" or mode-aware variants, add and use "e" versions, e.g.
for things like RDMSR, WRMSR, and CPUID, where the instruction uses only
bits 31:0, regardless of mode.

No functional change intended (all use of "e" versions is for cases where
the value is already truncated due to bouncing through a u32).

Subject: [PATCH 2656/5214] KVM: x86: Drop non-raw kvm_<reg>_write() helpers

Drop the non-raw, mode-aware kvm_<reg>_write() helpers as there is no
usage in KVM, and in all likelihood there will never be usage in KVM as
use of hardcoded registers in instructions is uncommon, and *modifying*
hardcoded registers is practically unheard of.  While there are a few
instructions that modify registers in mode-aware ways, e.g. REP string
and some ENCLS varieties, the odds of KVM needing to emulate such
instructions (outside of the fully emulator) are vanishingly small.

Drop kvm_<reg>_write() to prevent incorrect usage; _if_ a new instruction
comes along that needs to modify a hardcoded register, this can be
reverted.

No functional change intended.

Subject: [PATCH 2657/5214] KVM: nSVM: Use kvm_rax_read() now that it's
 mode-aware

Now that kvm_rax_read() truncates the output value to 32 bits if the
vCPU isn't in 64-bit mode, use it instead of the more verbose (and very
technically slower) kvm_register_read().

Note!  VMLOAD, VMSAVE, and VMRUN emulation are still technically buggy,
as they can use EAX (versus RAX) in 64-bit mode via an operand size
prefix.  Don't bother trying to handle that case, as it would require
decoding the code stream, which would open an entirely different can of
worms, and in practice no sane guest would shove garbage into RAX[63:32]
and then execute VMLOAD/VMSAVE/VMRUN with just EAX.

No functional change intended.

Unconditionally return %false for is_64_bit_hypercall() on 32-bit kernels

in a (very) hypothetical world where 32-bit KVM supports protected guests,
assuming a hypercall was made in 64-bit mode is flat out wrong.

Subject: [PATCH 2664/5214] KVM: guest_memfd: Treat memslot binding offset+size
 as unsigned values

When binding a memslot to a guest_memfd file, treat the offset and size as
unsigned values to fix a bug where the sum of the two can result in a false
negative when checking for overflow against the size of the file.  Passing
unsigned values also avoids relying on somewhat obscure checks in other
flows for safety, and tracks the offset and size as they are intended to be
tracked, as unsigned values.

On 64-bit kernels, the number of pages a memslot contains and thus the size
(and offset) of its guest_memfd binding are unsigned 64-bit values.  Taking
the offset+size as an loff_t instead of a uoff_t inadvertently converts
the unsigned value to a signed value if the offset and/or size is massive.

Locally storing the offset and size as signed values is benign in and of
itself (though even that is *extremely* difficult to discern), but
operating on their sum is not.

For the offset, KVM explicitly checks against a negative value, which might
seem like a bug as KVM could incorrectly reject a legitimate binding, but
that's not actually the case as KVM_CREATE_GUEST_MEMFD takes a signed value
for its size, i.e. a would-be-negative offset is also greater than the
maximum possible size of any guest_memfd file.

Regarding the size, while KVM lacks an explicit check for a negative value,
i.e. seemingly has a flawed overflow check, KVM restricts the number of
pages in a single memslot to the largest positive signed 32-bit value:

        if (id < KVM_USER_MEM_SLOTS &&
            (mem->memory_size >> PAGE_SHIFT) > KVM_MEM_MAX_NR_PAGES)
                return -EINVAL;

and so that maximum "size" will ever be is 0x7fffffff000.

The sum of the two is, however, problematic.  While the size is restricted
by KVM's memslot logic, the offset is not, i.e. the offset is completely
unchecked until the "offset + size > i_size_read(inode)" check.  If the
offset is the (nearly) largest possible _positive_ value, then adding size
to the offset can result in a signed, negative 64-bit value.  When compared
against the size of the file (guaranteed to be positive), the negative sum
is always smaller, and KVM incorrectly allows the absurd offset.

Opportunistically add missing includes in kvm_mm.h (instead of relying on
its parents).

Expand the gmem test macros to allow passing the VM to testcases, without
needing to plumb the VM into _every_ testcase, as the vast majority of
testcases only need the fd and size.

No functional change intended.

Subject: [PATCH 2666/5214] KVM: selftests: Add guest_memfd regression test
 signed offset+size bug

Add a regression (and proof-of-bug) testcase to ensure KVM rejects an
offset+size that would result in a negative value when computed as a signed
64-bit value.  KVM had a flaw where it would allow binding a memslot to a
guest_memfd instance even with a wildly out-of-range offset, if the offset
and size were both positive values, but the combined offset+size was
negative.

Use "0x7fffffffffffffffull - page_size", i.e. "INT64_MAX - page_size", for
the offset as the size of the guest_memfd file must be at least page_size
(KVM requires memslots and gmem files to be host page-size aligned).  I.e.
"INT64_MAX - page_size + size" is guaranteed to generate an offset+size
that is negative when converted to a signed 64-bit value *and* honors KVM's
alignment requirements.

Subject: [PATCH 2667/5214] KVM: selftests: Add a test for gPAT handling in L2

When KVM_X86_QUIRK_NESTED_SVM_SHARED_PAT is disabled, verify that KVM
correctly virtualizes the host PAT MSR and the guest PAT register for
nested SVM guests.

With nested NPT disabled:
 * L1 and L2 share the same PAT
 * The vmcb12.g_pat is ignored

With nested NPT enabled:
 * An invalid g_pat in vmcb12 causes VMEXIT_INVALID
 * RDMSR(IA32_PAT) from L2 returns the value of the guest PAT register
 * WRMSR(IA32_PAT) from L2 is reflected in vmcb12's g_pat on VMEXIT
 * RDMSR(IA32_PAT) from L1 returns the value of the host PAT MSR

Verify that save/restore with the vCPU in guest mode behaves as expected in
both cases, e.g. preserves both hPAT and gPAT when NPT is enabled.

kvm_mmu_notifier_invalidate_range_start() leaves range.lockless clear.
kvm_handle_hva_range() therefore takes KVM_MMU_LOCK(kvm) before invoking
the handler.

The guest_memfd path has the same locking contract:

  __kvm_gmem_invalidate_begin()
    kvm_mmu_unmap_gfn_range()
      kvm_unmap_gfn_range()

__kvm_gmem_invalidate_begin() explicitly takes KVM_MMU_LOCK(kvm) before
calling kvm_mmu_unmap_gfn_range().

So remove the local trylock and make the common locking contract explicit
with lockdep_assert_held_write() like x86.

Subject: [PATCH 2669/5214] KVM: riscv: Use an rwlock for mmu_lock

RISC-V KVM currently uses a spinlock for mmu_lock. That serializes all
G-stage MMU operations, including permission-only updates that do not
allocate or free page-table pages.

Use KVM's rwlock form of mmu_lock, as x86 and arm64 already do. Keep the
existing map, unmap and teardown paths on the write side. This prepares
RISC-V for read-side handling of G-stage permission updates.

Subject: [PATCH 2670/5214] KVM: riscv: Add a G-stage PTE cmpxchg helper

Permission-only G-stage PTE updates can run in parallel once they are
moved to the read side of mmu_lock. Plain set_pte() is not enough for
that case because another CPU may update the same PTE first.

x86 handles the same class of SPTE races with cmpxchg-based updates in
its fast page fault and TDP MMU paths. Add a small RISC-V helper for
atomic G-stage PTE updates. The helper reports contention to the caller
and flushes the target range only when the PTE value actually changes.

Subject: [PATCH 2671/5214] KVM: riscv: Update G-stage PTE permissions
 atomically

When a fault hits an existing G-stage leaf with the same PFN, KVM only
needs to update the PTE permissions. This path will be used by read-side
fault handling, so it must not overwrite a concurrent PTE update.

Use the cmpxchg helper when relaxing permissions on an existing leaf,
following the same concurrency model used by x86 for atomic SPTE
permission updates. Retry if another CPU changed the PTE first, and use
cpu_relax() while spinning.

Subject: [PATCH 2672/5214] KVM: riscv: Fast-path dirty logging write faults

With dirty logging enabled, guest writes often fault on an existing 4K
G-stage leaf that was write-protected only for dirty tracking. The slow
path still performs the full fault handling flow and takes mmu_lock for
write, even though the page-table shape does not change.

x86 handles the analogous case in its fast page fault path by atomically
making a writable SPTE writable again when the fault is only a
write-protection fault. Add the same style of fast path for RISC-V. If a
write fault hits an existing 4K leaf in a writable dirty-log memslot,
mark the page dirty and atomically set the PTE writable and dirty under
the read side of mmu_lock.

The dirty bitmap is updated before the PTE becomes writable again. The
PTE D bit is also set so systems that trap on a clear D bit do not fall
back to the slow path for a writable but clean PTE.

Subject: [PATCH 2674/5214] fs/ntfs3: bound attr_off in UpdateResidentValue
 against data_off

In do_action()'s UpdateResidentValue case (fslog.c:3307),
lrh->attr_off and lrh->redo_len come from the on-disk LRH.
When they satisfy aoff + dlen < attr->res.data_off, the
assignment

	attr->res.data_size = cpu_to_le32(aoff + dlen - data_off);

underflows to ~4 GiB (e.g. 0xFFFFFFF9 when aoff=0x10, dlen=1,
data_off=0x18).  Subsequent code that reads attr->res.data_size
to walk the resident attribute payload would then read up to
4 GiB past the 1024-byte MFT record allocation.

The existing mi_enum_attr() defense in fs/ntfs3/record.c:287
catches the corrupted data_size on the next attribute walk
and fails the mount, but only on the path that walks all
attributes.  A read site that picks an attribute by name and
reads its data_size without re-validating is not covered.
Validate aoff against data_off and asize at the source.

Reproduced under UML+KASAN on mainline 8d90b09e6741 via
pr_warn-only probe: with aoff=0x10 and data_off=0x18, the
post-assignment data_size is 0xfffffff9 (mount then fails
at -22 from mi_enum_attr).

Subject: [PATCH 2675/5214] fs/ntfs3: bound DeleteIndexEntryAllocation memmove
 length

In do_action()'s DeleteIndexEntryAllocation case, e->size comes
from an on-disk INDEX_BUFFER entry.  When e->size makes
e + e->size point past hdr + hdr->used,
PtrOffset(e1, Add2Ptr(hdr, used)) returns a negative ptrdiff_t
that is silently cast to a quasi-infinite size_t when passed
to memmove().  The memmove then walks past the destination
buffer.

The sibling DeleteIndexEntryRoot case at fslog.c:3540-3543
already carries the corresponding guard:

	if (PtrOffset(e1, Add2Ptr(hdr, used)) < esize ||
	    Add2Ptr(e, esize) > Add2Ptr(lrh, rec_len) ||
	    used + esize > le32_to_cpu(hdr->total)) {
		goto dirty_vol;
	}

Apply the same shape to the allocation-path case.  Also reject
esize == 0: memmove(e, e, ...) is a no-op and leaves
hdr->used unchanged, hiding a malformed entry from the
existing check_index_header() walk.

Reproduced under UML+KASAN on mainline 8d90b09e6741 by
mounting a crafted NTFS image: the unguarded memmove takes a
length of 0xffffffffffffff00 and the kernel oopses in
memmove+0x81/0x1a0 on the do_action+0x36a2 frame.

Subject: [PATCH 2676/5214] fs/ntfs3: bound copy_lcns dp->page_lcns[] index in
 analysis pass

In log_replay()'s analysis pass, after find_dp() returns a
valid DIR_PAGE_ENTRY for the (target_attr, target_vcn) tuple,
the copy_lcns block walks lrh->lcns_follow further entries:

	t16 = le16_to_cpu(lrh->lcns_follow);
	for (i = 0; i < t16; i++) {
	    size_t j = (size_t)(le64_to_cpu(lrh->target_vcn) -
	                        le64_to_cpu(dp->vcn));
	    dp->page_lcns[j + i] = lrh->page_lcns[i];
	}

find_dp() only validates that target_vcn falls within
[dp->vcn, dp->vcn + dp->lcns_follow), i.e., that the FIRST
cluster is covered.  The walk through the further entries is
not bounded against dp->lcns_follow.  For a malformed LRH
where target_vcn = dp->vcn + dp->lcns_follow - 1 and
lrh->lcns_follow > 1, the i > 0 writes overflow the dp's
allocated page_lcns[] array.

Add the missing j + lrh->lcns_follow <= dp->lcns_follow guard.

Reproduced under UML+KASAN on mainline 8d90b09e6741 as a
slab-out-of-bounds write of size 8 from log_replay+0x68d4 on
the mount path.

This is distinct from Pavitra Jha's 2026-05-02 patch
("fs/ntfs3: validate lcns_follow in log_replay conversion",
<20260502154252.164586-1-jhapavitra98@gmail.com>) which
addresses the separate version-0 dirty-page-table conversion
path's memmove(&dp->vcn, ...) call.  The two fixes are
complementary; both should land.

Subject: [PATCH 2677/5214] fs/ntfs3: validate lcns_follow in log_replay
 conversion

log_replay() converts DIR_PAGE_ENTRY_32 records into DIR_PAGE_ENTRY
records when replaying version 0 restart tables.

During this conversion, the memmove() length is derived directly from
the on-disk lcns_follow field:

	memmove(&dp->vcn, &dp0->vcn_low,
		2 * sizeof(u64) +
				le32_to_cpu(dp->lcns_follow) * sizeof(u64));

check_rstbl() validates restart table structure, but does not constrain
per-entry lcns_follow values relative to the entry size. A malformed
filesystem image can provide an oversized lcns_follow value, causing
the conversion memmove() to access memory beyond the bounds of the
allocated restart table buffer.

The same field is later used to bound iteration over page_lcns[],
so validating lcns_follow during conversion also prevents downstream
out-of-bounds access from the same malformed metadata.

Compute the maximum valid lcns_follow from the already-validated
restart table entry size and reject entries that exceed this bound.
Reuse the existing t16/t32 scratch variables already declared in
log_replay() to avoid introducing new declarations.

Subject: [PATCH 2679/5214] KVM: SEV: Move GHCB "usage" check out of
 sev_es_validate_vmgexit()

Move the check to verify the guest's requested GHCB out of
sev_es_validate_vmgexit() as the first step towards making said helper a
predicate whose sole purpose is to verify the guest has marked required
GHCB fields as valid.

Using a single "validate" helper sounds good on paper, but in practice it's
difficult to verify that KVM is performing the necessary sanity checks (the
usage of state is far removed from the relevant checks), makes it difficult
to understand that "legacy" exits are simply routed to KVM's existing exit
handlers, and most importantly, has directly contributed to a number of
bugs as adding case-statements to the validation subtly removes them from
the default path that rejects unknown exit codes with INVALID_EVENT.

Deliberately extract the usage code check first so as to preserve the order
of KVM's checks, even though future code extraction will technically fix
bugs.

No functional change intended.

Subject: [PATCH 2680/5214] KVM: SEV: Return INVALID_EVENT for SNP-only
 #VMGEXIT from non-SNP guest

Signal INVALID_EVENT, not MISSING_INPUT, if a non-SNP guest attempts to
invoke an SNP-only #VMGEXIT.  Opportunistically move the checks out of
sev_es_validate_vmgexit() to continue the march towards making said helper
a predicate whose sole purpose is to verify the guest has marked required
GHCB fields as valid.

Subject: [PATCH 2681/5214] KVM: SEV: Return INVALID_INPUT, not MISSING_INPUT,
 for bad GUEST_REQUEST input(s)

Return INVALID_INPUT, not MISSING_INPUT, if the guest provides an unaligned
address for a GUEST_REQUEST, and/or attempts to use the same page for the
source and destination.  The inputs are obviously invalid, not missing.

Opportunistically move the checks out of sev_es_validate_vmgexit(), to
continue the march towards reducing the scope of the helper, and to help
guide future changes into correctly handling bad input.

 sev_handle_vmgexit()

Handle unknown #VMGEXIT reasons in sev_handle_vmgexit(), not in
sev_es_validate_vmgexit().  This makes it _much_ more obvious that KVM
simply funnels "legacy" exits to the standard SVM interception handlers,
and is the final preparatory change needed to reduce the scope of
sev_es_validate_vmgexit().

No functional change intended.

Subject: [PATCH 2684/5214] KVM: SEV: Remove sometimes-used function-scoped
 "ret" from #VMGEXIT handler

Now that only two case-statements actually need a local "ret" variable,
refactor sev_handle_vmgexit() to have all flows return directly when
possible, and bury "ret" as "r" in the two paths that need to propagate a
return value from a helper.

No functional change intended.

Subject: [PATCH 2686/5214] usb: xhci: remove legacy 'num_trbs_free' tracking

Keeping track of free TRBs in a ring by adding and subtracting each time
a enqueue or dequeue pointer is modified has proven to be buggy and
complicated, especially over long periods of time.
The xhci driver has already moved to calculating free TRBs dynamically
based on ring size and the enqueue/dequeue positions.

The DbC path is the last user of 'num_trbs_free'. Rather than maintaining
two separate accounting mechanisms, remove the field entirely and switch
DbC to use xhci_num_trbs_free(). Since 'num_trbs_free' undercounts by one,
and xhci_num_trbs_free() does not, the check for sufficient free TRBs is
adjusted.

Subject: [PATCH 2687/5214] usb: xhci: Simplify xhci_quiesce()

The function reads USBCMD, clears some bits and writes it back.
Its treatment of the Run bit is weird: the bit is usually written
as 0, as we would expect, but it may also be written as 1 if both
its current value and USBSTS.HCHalted are observed as 1.

Per xHCI 5.4.2, HCHalted is 0 whenever Run is 1, so the above can
only happen due to buggy HW or SW, e.g. concurrent xhci_quiesce()
and xhci_start() execution.

It's unclear why we should treat such cases specially and write
the bit as 1. The logic comes from original PoC implementation
and has never been explained. Just write 0 every time, which
looks like the safer choice when the intent is to stop the xHC.

We could get in trouble if clearing Run causes some very broken
xHC to start running after it was halted, but no such case has
been documented. It seems the logic was just poorly thought out.

Subject: [PATCH 2688/5214] usb: xhci: Remove skip_isoc_td()

This function is pointless because usb_submit_urb() initializes all
isoc frame descriptors to -EXDEV and 0 length so that HCDs don't need
to do anything with transfers which were never executed.

Other HCDs rely on this (e.g. EHCI itd_complete()), so we can too.
This gets rid of a potentially dangereous function which could corrupt
memory if we weren't super careful to only call it on isoc URBs.

Also, set status to 0 rather than any random status determined by the
later TD which caused skipping. This status will be ignored anyway.

This URB flag was never supposed to have any effect on isoc endpoints.

No kernel code uses the flag except usb_sg_init(), on non-isoc only.
USBFS can't use it on isoc because proc_do_submiturb() rejects it.

A short transfer is a successful one, so reset the error count.
Otherwise, endpoints which always complete short are limited to
three retries per endpoint life rather than per URB.

It allows us to detect if DbC is stuck in connected state for too long,
and can later be used to enable runtime suspend if there is no activity
for some time

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a timeout between the detection of the debug host connection and
the DbC Run transition to ‘1’. Toggle the DCE bit to re-enable DbC in
order to retry the debug device enumeration process if the DbC run
transition takes too long.

Set the timeout to 2 seconds

See xhci specification section 7.6.4.1 "Debug Capability Initialization"

Also detect cable disconnect during enable and connected state.

Subject: [PATCH 2696/5214] xhci: Prevent queuing new commands if xhci is
 inaccessible

Refuse to queue a new command on the command ring if xHC is marked
inaccessible with the HCD_FLAG_HW_ACCESSIBLE.

HCD_FLAG_HW_ACCESSIBLE is set and cleared in suspend and resume.

Also print a warning if xhci is being suspended with commands
still pending on the command ring.

Subject: [PATCH 2697/5214] usb: xhci: refactor DCBAA struct

Embed the 'xhci_device_context_array' structure directly within 'xhci_hcd'
instead of allocating it as a separate block. Only the array of device
context addresses is now allocated separately.

Since the device context addresses are no longer part of an array
structure, rename 'dev_context_ptrs' to 'ctx_array' for clearer access
semantics.

Also remove the redundant comment next to the 'ctx_array' allocation;
using dma_alloc_coherent() for 64-bit * N allocations guarantees both
physically contiguous and properly aligned for 64-byte boundaries.
The xHCI section (5.4.6) refers to DCBAAP instead of DCBAA (6.1).

This change does not modify the number of host controller slots but
simplifies memory management and prepares the driver for a variable number
of HC slots in the future.

Subject: [PATCH 2698/5214] usb: xhci: allocate DCBAA based on host controller
 max slots

Allocate the Device Context Base Address Array (DCBAA) according to the
maximum number of device slots supported by the host controller, instead
of always allocating the absolute maximum of 255 entries.

The xHCI specification defines the DCBAA size as (MaxSlotsEnabled + 1)
entries. In the xhci driver there is currently no distinction between
MaxSlots and MaxSlotsEnabled, as all available slots are enabled during
initialization. As a result, 'max_slots' effectively represents both
values.

This change allows the xHCI driver to respect custom slot limits, reduces
unnecessary memory usage, and removes the obsolete "TODO" comment.

Subject: [PATCH 2699/5214] usb: xhci: allocate internal DCBAA mirror
 dynamically

Allocate the internal virtual device array dynamically based on the
maximum number of slots reported by the host controller. Previously,
the array was always allocated to the absolute maximum of 255 entries.

Repurpose the 'MAX_HC_SLOTS' macro to limit the number of enabled slots.
This mirrors how the maximum number of ports and interrupters are handled.

The allocation now uses kcalloc_node(), which zeroes the memory
automatically, making the explicit memset() call unnecessary.

 SET_XHCI_PLAT_PRIV_FOR_RCAR() macro

The SET_XHCI_PLAT_PRIV_FOR_RCAR() macro does not add much value (there
are only two users), and stands in the way of handling differences
between R-Car Gen2 and Gen3.  Remove it.

Subject: [PATCH 2701/5214] usb: host: xhci-rcar: Split R-Car Gen2 and Gen3
 .plat_start() handling

Currently, R-Car Gen2 and Gen3 share the same .plat_start() callback.
However, this single callback performs different operations, after
checking the XHCI's controller compatible value.

Avoid repeated checking of compatible values and reduce kernel size by
splitting this method in two separate functions.  Update
xhci_rcar_resume_quirk() to dispatch to the correct method by calling it
through the .plat_start() function pointer, too.

Subject: [PATCH 2702/5214] iio: adc: nxp-sar-adc: harden buffer ISR against
 per-channel read failure

nxp_sar_adc_isr_buffer() bails on the first channel-read failure
without calling iio_trigger_notify_done(), so the trigger use_count
is left incremented and iio_trigger_poll_chained() drops subsequent
dispatches until the device is rebound.

Reaching this path means a state machine has gone wrong (driver bug
or the SAR ADC in an unexpected state) rather than a transient bus
issue, so this is hardening rather than a bug fix. If the underlying
condition persists the device is wedged and needs an unbind anyway.

Call iio_trigger_notify_done() on the error exit too, matching the
success path. The nxp_sar_adc_read_notify() duplication is intentional
and avoids a goto label for a two-line bail-out, as suggested by David.

Subject: [PATCH 2705/5214] liveupdate: centralize state management into struct
 luo_ser

Transition the LUO to ABI v2, which centralizes state management into a
single struct luo_ser header.

Previously, LUO state was spread across multiple FDT properties and
subnodes. ABI v2 simplifies this by placing all core state, including
the liveupdate number and physical addresses for sessions and FLB
headers into a centralized struct luo_ser.

Note that this change introduces a semantic difference: the sessions
and FLB serialization formats are no longer completely independent of
the core LUO. Their metadata (such as physical addresses for sessions
and FLB headers) is now coupled to and managed via the centralized
struct luo_ser.

Subject: [PATCH 2706/5214] liveupdate: register luo_ser as KHO subtree

Entirely remove the LUO FDT wrapper since the FDT only carries the
compatible string and the pointer to the centralized struct luo_ser.
Instead, register the struct luo_ser via the KHO raw subtree
API, placing the compatibility string inside the structure itself.

Subject: [PATCH 2709/5214] kho: add support for linked-block serialization

Introduce a linked-block serialization mechanism for state handover.

Previously, LUO used contiguous memory blocks for serializing sessions
and files, which imposed limits on the total number of items that could
be preserved across a live update.

This commit adds the infrastructure for a more flexible, block-based
approach where serialized data is stored in a chain of linked blocks.
This is a generic KHO serialization block infrastructure that can be
used by multiple subsystems.

Subject: [PATCH 2710/5214] liveupdate: defer session block allocation and
 physical address setting

Currently, luo_session_setup_outgoing() allocates the session block and
sets its physical address in the header immediately. With upcoming
dynamic block-based session management, this makes the first block
different from the rest. Move the allocation to where it is first needed.

Subject: [PATCH 2711/5214] liveupdate: Remove limit on the number of sessions

Currently, the number of LUO sessions is limited by a fixed number of
pre-allocated pages for serialization (16 pages, allowing for ~819
sessions).

This limitation is problematic if LUO is used to support things such as
systemd file descriptor store, and would be used not just as VM memory
but to save other states on the machine.

Remove this limit by transitioning to a linked-block approach for
session metadata serialization. Instead of a single contiguous block,
session metadata is now stored in a chain of 16-page blocks. Each block
starts with a header containing the physical address of the next block
and the number of session entries in the current block.

Subject: [PATCH 2713/5214] selftests/liveupdate: Test session and file limit
 removal

With the removal of static limits on the number of sessions and files per
session, the orchestrator now uses dynamic allocation.

Add new test cases to verify that the system can handle a large number of
sessions and files. These tests ensure that the dynamic block allocation
and reuse logic for session metadata and outgoing files work correctly
beyond the previous static limits.

Subject: [PATCH 2717/5214] power: supply: max17042_battery: Use Current
 register in get_status

It can take a while for AvgCurrent to adjust after (un)plugging the charger. Use the instantaneous value in order to not confuse the userspace.

While at that, don't do unit conversion of the read value. The current code was prone to overflows and we only care about the sign anyway.

Subject: [PATCH 2720/5214] perf sample: Add file_offset field to struct
 perf_sample

Add a file_offset field to struct perf_sample so that event processing
callbacks can report the byte offset of the problematic event in
perf.data, letting users cross-reference with 'perf report -D' output.

Set sample.file_offset in perf_session__deliver_event(), which is the
common entry point for both file mode (mmap'd offset) and pipe mode
(running byte counter from __perf_session__process_pipe_events).

The assignment is placed after evsel__parse_sample(), which zeroes
the struct via memset.

Preserve file_offset through the deferred callchain delivery path by
storing it in struct deferred_event and restoring it after
evlist__parse_sample() in both evlist__deliver_deferred_callchain()
and session__flush_deferred_samples().

Subsequent patches will use this field in skip/stop warning messages.

failures.  This lets users cross-reference with 'perf report -D' output
to inspect the surrounding records and understand the corruption context.

Covers messages in perf_session__process_event() (alignment, min size,
swap failure), perf_session__deliver_event() (no evsel, parse failure,
CPU clamping), machines__deliver_event() (NAMESPACES, TEXT_POKE,
null-terminated string checks for MMAP/MMAP2/COMM/CGROUP/KSYMBOL), and
perf_session__process_user_event() (THREAD_MAP, CPU_MAP, STAT_CONFIG,
BPF_METADATA, HEADER_BUILD_ID).

Subject: [PATCH 2722/5214] perf sched: Include file offset in event skip
 messages

Add the perf.data file offset to the CPU out-of-bounds and
machine__resolve failure messages emitted when samples are skipped in
process_sched_switch_event(), process_sched_runtime_event(), and
timehist_sched_change_event().  Also switch event type from raw integer
to perf_event__name() string for readability.

Subject: [PATCH 2724/5214] perf tools: Include file offset and event type name
 in skip messages

Add the perf.data file offset and use perf_event__name() instead of raw
event type integers in the 'problem processing event, skipping it'
messages emitted by process_sample_event() callbacks across annotate,
c2c, diff, kmem, kvm, kwork, lock, report, script, and build-id.

This lets users cross-reference skipped events with 'perf report -D'
output.  Also add explicit #include "util/event.h" and <inttypes.h>
where needed to avoid depending on transitive includes.

Subject: [PATCH 2725/5214] perf timechart: Fix cat_backtrace() use-after-free
 on corrupted callchain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cat_backtrace() uses open_memstream() to build a backtrace string.
When an invalid callchain context is encountered, zfree(&p) frees
the memstream buffer, then the exit path calls fclose(f), which
flushes to the already-freed buffer — a use-after-free.  The function
then returns a dangling pointer that the caller passes to a handler
and subsequently double-frees.

Fix by replacing the zfree(&p) with a 'corrupted' flag.  At the exit
label, always fclose(f) first (which finalizes the buffer), then
conditionally free it when corrupted.  This ensures the memstream
contract is honored: the buffer remains valid until fclose().

While here, update the machine__resolve failure message to include
file_offset and the event type name, matching the pattern from the
preceding series.  Also update the three legacy power event handlers
under SUPPORT_OLD_POWER_EVENTS to include file_offset in their
out-of-bounds CPU messages for consistency.

Subject: [PATCH 2726/5214] perf sched: Replace BUG_ON on invalid CPU with
 graceful skip

latency_switch_event(), latency_runtime_event(), and map_switch_event()
use BUG_ON(cpu >= MAX_CPUS || cpu < 0) to validate the sample CPU.
When PERF_SAMPLE_CPU is absent from the sample type,
evsel__parse_sample() initializes sample->cpu to (u32)-1.  Casting
this to int yields -1, which triggers the BUG_ON and aborts perf sched.

The central CPU validation in perf_session__deliver_event() intentionally
preserves the (u32)-1 sentinel for downstream tools like perf script
and perf inject, so leaf callbacks must handle it themselves.

Replace the three BUG_ON calls with graceful skips using pr_warning(),
matching the existing pattern in process_sched_switch_event() and
process_sched_runtime_event() earlier in the same file.  Include the
file offset for cross-referencing with perf report -D.

Subject: [PATCH 2727/5214] perf test: Add file offset diagnostic test for
 corrupted perf.data

Add a shell test that verifies the file_offset diagnostic messages
work correctly when perf encounters corrupted events.

The test corrupts a MMAP2 event's size field in a recorded perf.data
file, then checks that perf report produces warning messages that
include both the file offset (e.g. "at offset 0x2738:") and the
event type name with numeric id (e.g. "MMAP2 (10)").

This exercises the diagnostic improvements from the file_offset
series, which retrofitted all skip/stop/error messages to include
the position and type of the problematic event.

Subject: [PATCH 2728/5214] perf env: Add perf_env__e_machine helper and use in
 perf_env__arch

Add a helper that lazily computes the e_machine and falls back to EM_HOST.
Use the perf_env's arch to compute the e_machine if available, using a
binary search for efficiency while handling duplicate rules.

Switch perf_env__arch to be derived from e_machine for consistency.
To support 32-bit compat binaries on 64-bit hosts during dynamic local
or live operations, unpopulated arch fallback paths query uname() at
runtime to dynamically resolve the correct host e_machine, safely
preventing bitness misclassification regressions.

Update session and header to use the helper to safely record e_machine
and flags without forcing premature thread scanning.

Subject: [PATCH 2729/5214] power: supply: max17042_battery: Remove unused
 platform-data plumbing

No in-tree user still provides `max17042_platform_data` or
`max17042_reg_data`. Move the simple runtime fields into
`struct max17042_chip`, populate them directly from DT or the default
hardware state, and drop the unused public platform-data interface.

While here, write the MAX17047/MAX17050 default `FullSOCThr` value
directly in probe instead of carrying it through an `init_data` table.

Subject: [PATCH 2730/5214] perf tests topology: Switch env->arch use to
 env->e_machine

Some arch string comparisons weren't normalized. Avoid potential
issues with normalized names vs uname values by swtiching to using the
e_machine.

Subject: [PATCH 2731/5214] perf env, dso, thread: Add _endian variants for
 e_machine helpers

Add perf_arch_is_big_endian(), dso__read_e_machine_endian(),
dso__e_machine_endian(), and thread__e_machine_endian() to support
bi-endianness and cross-architecture analysis without breaking the
existing API.

These helpers allow querying the absolute endianness of a DSO or
thread, which is required for tools like Capstone that need to set the
correct disassembly mode.

Subject: [PATCH 2732/5214] perf capstone: Determine architecture from
 e_machine

Avoid the use of arch string that is imprecise and use the
e_machine. Do more e_machine to capstone machine translations adding
MIPS and RISCV. Remove unnecessary maybe_unused annotations.

Subject: [PATCH 2735/5214] perf machine: Use perf_env e_machine rather than
 arch

The arch string is derived from uname and may be normalized causing
potential differences meaning the ELF machine can be more
precise. Reduce the scope of machine__is as often it is better to use
a thread for the e_machine rather than the machine. Switch from string
to ELF machine constant comparisons.

Subject: [PATCH 2742/5214] perf env: Refactor perf_env__arch_strerrno

The previous approach maps an architecture string to a function
pointer to a function that takes an int errno value and returns a
string. The new approach takes an e_machine and an errno value and
returns a string.

As the only call site is in builtin-trace.c, the e_machine is already
present and potentially more specific than the perf_env arch string
that is a single global value.

Since the errno-to-name mapping is now generated statically and no
longer depends on libtraceevent, we can remove the HAVE_LIBTRACEEVENT
guards entirely, making perf_env__arch_strerrno unconditionally
available.

The major complication in this approach is having the shell script
that generates the C code map a linux directory name to the matching
ELF machine constants. To ensure compatibility with older hosts that
have older glibc versions, output fallback definitions for newer ELF
machine constants (EM_AARCH64, EM_CSKY, EM_LOONGARCH) if they are not
defined in the system <elf.h>.

Subject: [PATCH 2744/5214] perf env: Add mutex to protect lazy environment
 initialization

Introduce a mutex to 'struct perf_env' to safely protect lazy
metadata setup, such as os_release or e_machine resolution,
preventing concurrent initialization data races and memory leaks
during multi-threaded profiling or symbol loading.

From 979e87ab1f258036aab9ed874aecede0163586e5 Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Tue, 2 Jun 2026 08:25:15 -0700
Subject: [PATCH 2746/5214] perf symbol: Add setters for bitfields sharing a
 byte to avoid concurrent update issues

A problem with putting bitfields into struct symbol is that other bits in
the symbol could be updated concurrently and only one update to the
underlying storage unit happen, leading to lost updates.

To avoid this, use atomics to atomically read or set part of 16-bits
of flags in the symbol. Add accessors to simplify this.

The idle value has 3 values in preparation for a later change that
will lazily update it.

From 044462f6f64d16e9f51a695719a3248e277c1d4e Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Tue, 2 Jun 2026 08:25:16 -0700
Subject: [PATCH 2747/5214] perf symbol: Lazily compute idle

Switch from an idle boolean to a helper symbol__is_idle function. In
the function lazily compute whether a symbol is an idle function
taking into consideration the kernel version and architecture of the
machine. As symbols__insert no longer needs to know if a symbol is for
the kernel, remove the argument.

To protect against drop-filtering of legitimate setup, online, or hotplug
management functions (such as intel_idle_init), x86 matches are strictly
constrained to exact known run-loops (intel_idle, intel_idle_irq,
mwait_idle, mwait_idle_with_hints).

If the target environment OS release is unresolvable (such as on guest
traces), default to treating psw_idle as idle to prevent false
negatives and match legacy trace behavior safely.

This change is inspired by mailing list discussion, particularly from
Thomas Richter <tmricht@linux.ibm.com> and Heiko Carstens
<hca@linux.ibm.com>:

Subject: [PATCH 2748/5214] power: supply: max17042_battery: use ModelCfg
 refresh on max17055

Unlike other models, max17055 doesn't require cell characterization data
and operates on a smaller set of input variables (`DesignCap`, `VEmpty`,
`IChgTerm`, and `ModelCfg`). Those values can be filled in through
`max17042_override_por_values()`, but the refresh bit has to be set
afterward in order to make them apply.

 imbalance

The driver reuses the OF node of the parent multi-function device but
fails to take another reference to balance the one dropped by the
platform bus code when unbinding the MFD and deregistering the child
devices.

Fix this by using the intended helper for reusing OF nodes.

 nvmem_device_put() causing reference leak
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In cpcap_battery_detect_battery_type(), the reference to an nvmem
device obtained via nvmem_device_find() is not released with
nvmem_device_put() on the success or read-failure paths, causing a
permanent reference leak. The driver’s retry logic on subsequent
battery property reads can compound this leak, preventing the nvmem
device from ever being freed.

We propagate CPTR_EL2.E0POE from a L1 into the L0 configuration, but
we key this on the L1 guest supporting FEAT_S2POE. This is obviously
wrong, as this bit is solely concerned with Stage-1 translation.

Fix this by making the update depend on FEAT_S1POE.

Subject: [PATCH 2753/5214] KVM: arm64: Wire AT S1E1A in the system instruction
 handling table

Despite having handling code for AT S1E1A, the instruction was
never plugged into the system instruction table, leading to an
exception being injected in the guest.

If the guest is Linux and using the __kvm_at() helper, the exception
is actually handled in the helper, and KVM continues more or less
silently by reentering the guest. Not exactly what you'd expect.

Fix this by plugging the emulation code where required.

Subject: [PATCH 2754/5214] arm64: cpufeature: Expose ID_AA64ISAR2_EL1.ATS1A to
 KVM

KVM needs to know if the HW implements FEAT_ATS1A in order to correctly
sanitise HFGITR_EL2.ATS1E1A, which otherwise defaults to RES0 and
AT S1E1A traps are handled as UNDEF.

Solves this by exposing ID_AA64ISAR2_EL1.ATS1A to the rest of the kernel.

Subject: [PATCH 2756/5214] KVM: arm64: nv: Fully update VNCR fixmap state in
 kvm_translate_vncr()

kvm_translate_vncr() first invalidates the pseudo-TLB entry and
corresponding fixmap in anticipation of installing a new translation.

While the fixmap invalidation does clear the mapping from host stage-1,
it does not clear the L1_VNCR_MAPPED flag. Depending on the state of the
VNCR TLB at vcpu_put(), this could potentially precipitate a BUG_ON() if
vt->cpu is reset.

Share a helper with kvm_vcpu_put_hw_mmu(), ensuring that KVM's view of
the VNCR fixmap is in sync with the state of the VNCR TLB. Give it a
slightly verbose name to make it obvious that it is meant to be used
local to a CPU, unlike other VNCR TLB maintenance.

__kvm_at_s*() are expected to return -EAGAIN if the page table walk
raced with a concurrent update to a page table descriptor, which is
interpreted as a signal to restart the trapping instruction.

While this mostly works, __kvm_at_s12() silently eats the return from
__kvm_at_s1e01() and consumes an uninitialized PAR value. Propagate the
nonzero return instead.

The minimal system voltage (VSYSMIN) is meant to protect the battery from
dangerous over-discharge. When the device tree provides a value for the
minimum design voltage of the battery, the user should not be allowed to
set a lower VSYSMIN, as that would defeat the purpose of this protection.

Flip the clamping logic when setting VSYSMIN to ensure that battery design
voltage is respected.

Subject: [PATCH 2763/5214] power: supply: bq257xx: Add fields for 'charging'
 and 'overvoltage' states

The driver currently reports the 'charging' and 'overvoltage' states based
on a logical expression in the get_charger_property() wrapper function.
This doesn't scale well to other chip variants, which may have a different
number and type of hardware reported conditions which fall into these
broad power supply states.

Move the logic for determining 'charging' and 'overvoltage' states into
chip-specific accessors, which can be overridden by each variant as
needed.

This helps keep the get_charger_property() wrapper function chip-agnostic
while allowing for new chip variants to be added bringing their own logic.

 of_device_get_match_data()

Use of_device_get_match_data() to fetch the reset syscfg data directly
instead of open-coding an of_match_device() lookup.

This also lets the driver drop the of_device.h include.

Subject: [PATCH 2766/5214] power: supply: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace and commas.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it
exports, because this is easier to read and verify.  It also makes more
sense since #ifdef for ACPI or OF could hide both of them.

Most of the privers already have this correctly placed, so adjust
the missing ones.  No functional impact.

Subject: [PATCH 2769/5214] power: supply: cpcap-charger: include missing
 <linux/property.h>

This file uses dev_fwnode() without including the proper header for it,
relying on transitive header inclusion from:

drivers/power/supply/cpcap-charger.c
- include/linux/phy/omap_usb.h
  - include/linux/usb/phy_companion.h
    - include/linux/usb/otg.h
      - include/linux/phy/phy.h
        - drivers/phy/phy-provider.h
          - include/linux/of.h
            - include/linux/property.h

With the future removal of drivers/phy/phy-provider.h from
include/linux/phy/phy.h, this transitive inclusion would break.

Subject: [PATCH 2771/5214] clk: keystone: don't cache clock rate

The TISCI firmware will return 0 if the clock or consumer is not
enabled although there is a stored value in the firmware. IOW a call to
set rate will work but at get rate will always return 0 if the clock is
disabled.
The clk framework will try to cache the clock rate when it's requested
by a consumer. If the clock or consumer is not enabled at that point,
the cached value is 0, which is wrong. Thus, disable the cache
altogether.

Subject: [PATCH 2772/5214] clk: keystone: sci-clk: fix application of sizeof
 to pointer

Coccinelle (scripts/coccinelle/misc/noderef.cocci) reports:

  drivers/clk/keystone/sci-clk.c:391:8-14: ERROR: application of
  sizeof to pointer

In sci_clk_get(), 'clk' is declared as 'struct sci_clk **', so
sizeof(clk) is sizeof(struct sci_clk **) which is the size of a
pointer rather than the size of an array element. provider->clocks
is an array of 'struct sci_clk *', so the canonical size argument
to bsearch() is sizeof(*clk) (i.e. sizeof(struct sci_clk *)).

The two values are equal on every supported architecture, so this
is correctness/idiom, not a runtime fix, but the new form matches
the rest of the bsearch() callers in the tree and silences the
Coccinelle warning the script flagged.

Subject: [PATCH 2773/5214] thunderbolt: debugfs: Fix margining error counter
 buffer leak

When USB4 lane margining debugfs write support is enabled,
margining_error_counter_write() copies the user input with
validate_and_copy_from_user(). This allocates a temporary page that is
only needed while parsing the requested error counter mode.

The function currently returns without freeing that page. This leaks one
page per write to the error_counter debugfs file, including successful
writes and writes that later fail while taking the domain lock or because
software margining is not enabled.

Free the temporary page once parsing has completed, and also before
returning from the invalid-input path.

Subject: [PATCH 2774/5214] RISC-V: KVM: Document a TOCTOU race in SBI system
 suspend handler

The SUSP handler checks that all other vCPUs are stopped before
entering system suspend, but a concurrent HSM HART_START can start
a vCPU after it has already passed the check.

This is a known TOCTOU race. We do not fix it because:
1. Triggering it requires a pathological guest.
2. Only guest state is at risk, not host integrity.
3. Userspace can double-check vCPU states before suspend.

Add a comment documenting the race and the rationale for not fixing it.

Subject: [PATCH 2775/5214] RISC-V: KVM: Fix NULL pointer dereference in AIA
 IMSIC functions

Fuzzer reported a NULL pointer dereference in
kvm_riscv_vcpu_aia_imsic_put() when a VCPU's imsic_state was NULL while
kvm_riscv_aia_initialized() returned true.

The global initialized flag is set per-VM in aia_init(), but imsic_state
is allocated per-VCPU in kvm_riscv_vcpu_aia_imsic_init(). If a VCPU is
created after aia_init() has already run, its imsic_state remains NULL
while the global flag is true. When this VCPU is preempted, kvm_sched_out()
calls kvm_arch_vcpu_put() -> kvm_riscv_vcpu_aia_put() ->
kvm_riscv_vcpu_aia_imsic_put() which dereferences NULL.

Add NULL pointer guards to kvm_riscv_vcpu_aia_imsic_put(), consistent with
the NULL checks already present in all other functions in the same file.

Also add a NULL guard to kvm_riscv_vcpu_aia_imsic_release() and
kvm_riscv_vcpu_aia_imsic_has_interrupt() for the same reason.

Subject: [PATCH 2777/5214] RISC-V: KVM: Fix timer state restore

The KVM_REG_RISCV_TIMER_REG(state) one-reg write passes the value
written by userspace to kvm_riscv_vcpu_timer_next_event() when
re-enabling the timer.

That value is the timer state, KVM_RISCV_TIMER_STATE_ON, not the
timer compare value. During migration or state restore, userspace
restores the compare register separately, which stores the target
cycle in t->next_cycles. Re-arming the timer with the state value
schedules the next event at cycle 1 instead of the restored compare
value, causing the virtual timer to fire too early.

Use the restored compare value from t->next_cycles when turning the
timer back on.

Subject: [PATCH 2778/5214] dt-bindings: dma: nvidia,tegra186-gpc-dma: Make
 reset optional

On Tegra264, GPCDMA reset control is not exposed to Linux and is handled
by the boot firmware.

Although reset was not exposed in Tegra234 as well, the firmware supported
a dummy reset which just returns success on reset without doing an actual
reset. This is also not supported in Tegra264 BPMP. Therefore mark 'reset'
and 'reset-names' properties as required only for devices prior to
Tegra264.

This also necessitates that the Tegra264 compatible be standalone and
cannot have the fallback compatible of Tegra186. Since there is no
functional impact, we keep reset as required for Tegra234 to avoid
breaking the ABI.

for each transfer and was wrapped within tegra_dma_sg_req. Move the
values directly into tegra_dma_sg_req and use channel_regs for

the struct channel_regs. This prepares for the register offset change

Subject: [PATCH 2782/5214] dmaengine: tegra: Support address width > 39 bits

Tegra264 supports address width of 41 bits. Unlike older SoCs which use
a common high_addr register for upper address bits, Tegra264 has separate
src_high and dst_high registers to accommodate this wider address space.

Add an addr_bits property to the device data structure to specify the
number of address bits supported on each device and use that to program
the appropriate registers.

Update the sg_req struct to remove the high_addr field and use
dma_addr_t for src and dst to store the complete addresses. Extract
the high address bits only when programming the registers.

Subject: [PATCH 2784/5214] dmaengine: tegra: Use iommu-map for stream ID

Use 'iommu-map', when provided, to get the stream ID to be programmed
for each channel. Iterate over the channels registered and configure
each channel device separately using of_dma_configure_id() to allow
it to use a separate IOMMU domain for the transfer. However, do this
in a second loop since the first loop populates the DMA device channels
list and async_device_register() registers the channels. Both are
prerequisites for using the channel device in the next loop.

Channels will continue to use the same global stream ID if the
'iommu-map' property is not present in the device tree.

Subject: [PATCH 2786/5214] coresight: ultrasoc-smb: Fix OOB write in
 smb_sync_perf_buffer()

When the SMB sink is used as a perf AUX sink, smb_update_buffer() calls
smb_sync_perf_buffer() to copy hardware trace data into the perf AUX ring
buffer pages. It derives pg_idx = head >> PAGE_SHIFT from @head, which is
handle->head, and indexes dst_pages[pg_idx]. The pg_idx %= nr_pages
normalization is only applied after the first loop iteration.

This leaves the initial page index underived from the buffer size, which
can result in an out-of-bounds write past dst_pages[] when head exceeds
the AUX buffer size.

Normalize head modulo the AUX buffer size before deriving the page index
and offset, mirroring tmc_etr_sync_perf_buffer().

Use platform_get_irq_optional() to retrieve the interrupt resource
instead of directly parsing and mapping the OF node via
irq_of_parse_and_map().  This is the standard pattern for platform

is missing.

Subject: [PATCH 2789/5214] perf bench: Add --write-size option to sched pipe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The default ping-pong uses sizeof(int) (4 bytes) per iteration, which
exercises only the pipe-buffer merge path and keeps allocation entirely
out of the picture. That makes the bench a useful scheduler / context-
switch latency probe but unable to surface anything from the pipe
page-allocation hot path.

Add a -s/--write-size option that sets the bytes written and read per
ping-pong iteration. The buffer is allocated for each side via struct
thread_data and replaces the on-stack int previously used. The default
remains sizeof(int) so existing invocations are unchanged.

With --write-size set above PAGE_SIZE the bench drives anon_pipe_write()
through alloc_page() (or the bulk pre-alloc, if the relevant patch is
applied), which is what we want when measuring pipe locking and page
allocation work.

The bench is a ping-pong: both sides call write() before read(), so a
single write_size payload must fit entirely in the pipe buffer or both
sides deadlock waiting for the other to drain.

Resize the pipe via F_SETPIPE_SZ to match write_size (skipped at the
sizeof(int) default), and error out cleanly when the request exceeds
/proc/sys/fs/pipe-max-size.

Subject: [PATCH 2790/5214] perf lock: Fix non-atomic max/time and min_time
 updates in contention_data

The update_contention_data() had a FIXME noting that max_time and
min_time updates lacked atomicity. Two CPUs could simultaneously read a
stale value, pass the comparison check and race on the write-back, with
the smaller value potentially overwriting the larger one and silently
corrupting the statistics.

Fix this by replacing the bare conditional assignments with a
bpf_loop()-based CAS retry loop. Each field tracks its own convergence
independently via max_done/min_done flags in cas_ctx, so a successful
CAS on one field is never retried even if the other field needs more
attempts.

Subject: [PATCH 2791/5214] perf build: Compile BPF skeletons with -mcpu=v3

The lock_contention BPF program uses __sync_val_compare_and_swap() to
atomically update the max_time and min_time fields in contention_data.

This builtin lowers to the BPF_CMPXCHG instruction, which is only
available in BPF ISA v3. Without an explicit -mcpu flag, Clang targets
BPF v1/v2 by default on older toolchains (Clang < 18), causing build
errors when v3 instructions are emitted.

Add -mcpu=v3 to CLANG_OPTIONS, which is used exclusively in the BPF
skeleton compilation rule.

Subject: [PATCH 2792/5214] tools build: Fix feature checks to touch target
 files on success

In tools/build/feature/Makefile, test-clang-bpf-co-re.bin and
test-bpftool-skeletons.bin redirected grep output but never touched or
created the $@ target file upon success.

Because the target file was never created on disk, Kbuild could never cache
the result of the check. Consequently, Make treated the prerequisite as
missing and continuously re-executed the Clang BPF backend and bpftool
feature checks on every single sub-make evaluation during build startup, or
on every incremental build.

Refactor both feature check recipes to touch $@ on success. For
test-clang-bpf-co-re.bin, group the shell pipeline within curly braces
and redirect both stdout and stderr to .make.output to allow errors to
be inspected and not appear in build output.

List test-clang-bpf-co-re.bin's input C file as a dependency so
modification triggers a rebuild. For test-bpftool-skeletons.bin, add it
to the FILES list so that it will be cleaned.

Subject: [PATCH 2793/5214] perf stat: Add aggr_nr metric parser support

Introduce the `aggr_nr` function to the metric expression parser.
`aggr_nr` allows metric formulas to dynamically utilize the number of
aggregated targets (`aggr->nr`) instead of relying on the static
`source_count` (which represents the static socket or node count).

This adds the `AGGR_NR` token to the lexer and parser, updates the
expression parsing context helpers to store `aggr_nr`, and feeds
`aggr->nr` from the aggregation structure in `prepare_metric`.

Subject: [PATCH 2794/5214] perf stat: Use aggr_nr scaling for Intel uncore
 miss latency metrics

Update `metric.py` to support the new `aggr_nr` keyword in the python
metric generator. Replace the usage of `source_count` with `aggr_nr` in
`IntelMissLat` inside `intel_metrics.py` so that uncore latency metrics
(like `lpm_miss_lat`) scale correctly on multi-socket and SNC systems when
aggregated globally.

Additionally, update the validation bypass logic in `CheckEveryEvent()`
inside `metric.py` to whitelist 'cha' and 'uncore' events. This
prevents validation failures when compiling metrics referencing these
PMU-specific uncore events.

Subject: [PATCH 2795/5214] perf: Fix off-by-one stack buffer overflow in
 kallsyms__parse()

In kallsyms__parse(), the loop reading symbol names iterates with i <
sizeof(symbol_name), which allows i to reach sizeof(symbol_name) upon
loop exit. The subsequent symbol_name[i] = '\0' then writes one byte
past the end of the stack-allocated symbol_name[] array.

Fix this by changing the loop bound to KSYM_NAME_LEN, so the null
terminator always lands within the array. The overflow is triggerable by
a kallsyms entry with a symbol name of KSYM_NAME_LEN+1 or more
characters (e.g., long Rust mangled names or a malicious
/proc/kallsyms).

Subject: [PATCH 2796/5214] perf tools: Ensure event leader stays at head of
 evlist after sorting

For evlist of a certain event/metric, the HEAD should be the event
leader. In some scenarios where uncore_xxx_0 does not exist, the event
leader is not the first element after sorting. For example, on my test
machine uncore_iio_0 does not exist, the event leader is uncore_iio_2.

However, in `evlist__cmp`, it was reordered based on the PMU name, which
makes uncore_iio_1 the HEAD of evlist, breaking the following merge
logic in `evsel__merge_aliases`.

The patch adds a loop at the end of
`parse_events__sort_events_and_fix_groups` to make sure the first
wildcard match is the earliest entry in the list, updating pointers
accordingly without breaking reordering detection.

Tested on device lacks uncore_iio_0, and `perf test` looks good.

Subject: [PATCH 2797/5214] perf annotate: Fix crashes on empty annotate
 windows

Annotate can open with an empty window if the disassembly tool fails.
After the linked change, the TUI started assuming there was a current
annotation line and could assert or segfault in the seek, refresh, and
source-toggle paths.

Handle empty annotate windows explicitly: set the asm entry count before
resetting the browser, return early when refreshing an empty list, and
ignore source line toggle when there is no current annotation line.

Fixes the following when opening an annotation:

  perf: ui/browser.c:125: ui_browser__list_head_seek: Assertion `pos != NULL' failed.
  Aborted

Subject: [PATCH 2798/5214] perf tpebs: Fix concurrent stop races and PID reuse
 hazards in tpebs_stop

Parallel verbose test execution can trigger a race condition in tpebs_stop
if called concurrently or when PID reuse occurs, causing finish_command()
to block or reap the wrong process.

Introduce a `tpebs_stopping` flag inside intel-tpebs.c to prevent
redundant stop execution paths, and safely restore the `cmd.pid`
temporarily only during `finish_command()` to ensure it is properly reaped,
while preventing other threads from referencing it.

Subject: [PATCH 2800/5214] perf pmu-events: Add API to get metric table name
 and iterate tables

Add name field to struct pmu_metrics_table and populate it in generated
tables. Add pmu_metrics_table__name() to retrieve the name. Add
pmu_metrics_table__for_each_table() to iterate over all known metric
tables.

This will be used to break apart slow metric tests per table.

Subject: [PATCH 2801/5214] perf test: Drain pipe after child finishes to avoid
 losing output

When running tests in parallel, the parent process reads output from the
child's pipe. However, it might exit the loop as soon as the child is
detected as finished, potentially missing data that arrived in the pipe
just after the last poll or before the loop terminated.

Address this by draining the pipe after the main loop in finish_test.

Subject: [PATCH 2802/5214] perf test: Support dynamic test suites with setup
 callback and private data

Add void *priv to struct test_case to allow passing per-test context.
Add int (*setup)(struct test_suite *) to struct test_suite to allow
dynamic generation of test cases. Update build_suites() to invoke the
setup callback for each suite if present, ensuring dynamic cases are
available before listing or running.

Subject: [PATCH 2803/5214] perf test pmu-events: A sub-test per metric table

Break apart the slow "Parsing of PMU event table metrics" tests into one
pair of tests (real and fake PMU) per metric table found, storing the
specific table pointer in priv data. Implement setup_pmu_events_suite()
to dynamically allocate and populate these test cases. Split static
parser tests out into a separate test__parsing_fake_static() test case.
Update test__parsing() and test__parsing_fake() to retrieve the specific
table from priv data and test only that table, maintaining fallback
compatibility if priv is NULL.

Running these individual tests in parallel significantly reduces overall
test execution time.

Subject: [PATCH 2804/5214] tools subcmd: Robust fallback and existence checks
 for process reaping

Update check_if_command_finished() and wait_or_whine() to handle invalid
PIDs gracefully (<= 0) by setting cmd->finished = 1 and returning early.
This avoids executing waitpid(-1, ...) or waitpid(0, ...) downstream,
which can block or reap parallel tests' exit status causing state
corruption.

Introduce a fallback mechanism in check_if_command_finished() using
waitpid(..., WNOHANG) when /proc/<pid>/status is inaccessible (e.g. due
to EMFILE/ENFILE) to safely check and reap finished children.

Subject: [PATCH 2805/5214] perf test: Refactor parallel poll loop to drain all
 pipes simultaneously

When running tests in parallel with verbose output (-v), child processes
write to pipes. If a test produces significant output (e.g. Granite
Rapids metric parsing printing hundreds of lines), it fills the 64KB
pipe buffer and blocks.

Previously, the parent harness (finish_test) only polled the pipe of the
current test waiting to be printed. Other children blocked indefinitely
until the parent reached them, severely sequentializing execution.

Address this by implementing finish_tests_parallel() to poll and drain
output pipes from all running children simultaneously into per-child
buffers, employing safe strbuf_addstr string operations alongside
thorough variable orderings for strict ISO C90 compliance. Reaping
occurs out of order as children finish, while final result printing
remains strictly in order.

This drops parallel verbose execution time for the PMU events suite from
~35 seconds down to ~5.9 seconds.

Subject: [PATCH 2806/5214] perf test: Show snippet failure output for
 verbose=1

Currently, when running tests in verbose mode (-v), if a test case
fails, the entire raw standard error buffer is dumped to stderr via
fprintf(stderr, "%s", child->err_output.buf). For tests that generate
massive amounts of debugging or logging output before dying, this
results in multi-page terminal dumps where highly critical diagnostic
keywords (error, fail, segv) are easily lost.

Implement a smart, bounded snippet string processor to improve
failure triaging:

1. Introduce a configurable quota limit static unsigned int
   failure_snippet_lines = 10; accessible via a new command-line option
   --failure-snippet-lines <N>.

2. Parse the raw error buffer dynamically into lines and run a
   three-pass extraction algorithm:
   - Pass 0: Always select the very first line of the log as an initial
     outline marker.
   - Pass 1: Scan forward from the top of the log to pick up to N lines
     that contain case-insensitive failure keywords (error, fail,
     segv, abort) to isolate the root cause. Automatically pull in
     the immediate subsequent line as highly-prioritized context.
     Allow adjacent matching lines to overlap without dropping context
     by evaluating keywords for all lines (e.g. when "Failed to
     report" is followed by "Error:").
   - Pass 2: If quota remains, scan backward from the absolute tail of
     the log to capture trailing crash or abort context.

3. Output the selected lines in their original chronological order,
   inserting a clear ... separator between non-contiguous line jumps.

4. Wrap matched failure keywords dynamically in bold red
   (PERF_COLOR_RED) to immediately draw the eye to failures.

5. Invoke the smart processor purely when verbose == 1 && ret ==
   TEST_FAIL in both finish_test and finish_tests_parallel, leaving
   raw full-output dumping completely untouched when running highly
   verbose (-vv).

Subject: [PATCH 2807/5214] perf test: Add summary reporting

Currently, when running test suites (perf test), users must scroll
through hundreds of lines of console output to manually tally the number
of passed, skipped, or failed test cases.

Introduce an automated, global execution summary printed at the absolute
tail of the test run:

1. Track counts mid-flight inside the print_test_result() accumulator,
   clearly separating pass counts into standalone main tests vs.
   individual subtests (where num_test_cases > 1).

2. Accumulate the precise descriptions of all failed test cases
   directly into a global string buffer, formatted with their suite
   indices (e.g., 3.1: Parse event definition strings) for effortless
   cross-referencing.

3. Define a summary printer function print_tests_summary() that
   emits a colored outline of the final pass, skip, and fail totals,
   followed by the explicit list of failed tests.

4. Invoke the summary printer right before freeing the test array at
   the absolute tail of __cmd_test(), guaranteeing that the summary is
   successfully printed even if an internal emergency signal cleanup
   occurs or if the user interrupts the run early.

Example output:
```
$ sudo perf test -v
  1: vmlinux symtab matches kallsyms                                 : Skip
  2: Detect openat syscall event                                     : Ok
  3: Detect openat syscall event on all cpus                         : Ok
...
163: perf trace summary                                              : Ok

=== Test Summary ===
Passed main tests : 123
Passed subtests   : 145
Skipped tests     : 22
Failed tests      : 6
List of failed tests:
   92: perf kvm tests
   95: kernel lock contention analysis test
  120: perf metrics value validation
  124: Check branch stack sampling
  143: perftool-testsuite_probe
  158: test Intel TPEBS counting mode
```

Subject: [PATCH 2808/5214] perf test: Fix subtest status alignment for
 multi-digit indexes

When running perf test, the status column (: Ok) became misaligned when
subtest indexes reached 2 or 3 digits (e.g. 9.100 vs 9.9 vs 10.1). This
occurred because the subtest description field width (subw) was
statically fixed to width - 2, assuming all subtest index prefixes were
exactly 7 characters wide.

Dynamically calculate subw based on the exact character length of the
test suite and subtest index prefix. This ensures the status column is
perfectly aligned vertically across all test outputs regardless of
subtest index digit count.

Subject: [PATCH 2809/5214] perf test: Skip shebang and SPDX comments in shell
 test descriptions

When extracting shell test descriptions in tests-scripts.c, the parser
skipped the first line assuming it was the shebang (#!/bin/sh) and then
read the first comment line on line 2 as the test description.

However, checkpatch.pl expects shell scripts to declare their SPDX
license identifier on line 2 (# SPDX-License-Identifier: ...). This
caused the test harness to extract the SPDX license string as the test
description.

Refactor shell_test__description to use io__getline, skipping both
shebang and SPDX comment lines. This allows shell tests to include
standard SPDX headers without breaking test suite description
extraction.

Subject: [PATCH 2810/5214] perf test: Split monolithic 'util' test suite into
 sub-tests

Refactor the monolithic 'util' test suite into distinct 'String
replacement' and 'BLAKE2s hash' sub-tests using the struct test_case
framework. This improves test reporting granularity and is used in a
subsequent perf test for JUnit XML test result reporting.

Subject: [PATCH 2811/5214] perf test: Add -j/--junit option for JUnit XML test
 reports

Add a -j/--junit command line option to generate standard JUnit XML
format test reports. The generated file defaults to 'test.xml' if no
filename is specified, but allows users to override the path (e.g.
-jmytest.xml).

The XML report captures individual test suite and subtest execution
latency, alongside XML-escaped failure logs and skip reasons, while
preserving the full multi-process concurrency speed of parallel test
execution.

Subject: [PATCH 2814/5214] perf test: Add shell test to validate JUnit XML
 reporting output

Add a shell test script (test_test_junit_output.sh) to execute perf test
with the -j/--junit option and validate that the generated test report
complies perfectly with standard XML formatting using Python's
ElementTree XML parser.

Subject: [PATCH 2815/5214] perf test: Remove /usr/bin/cc dependency from Intel
 PT shell test

In test_intel_pt.sh, the test script compiled two external C programs at
runtime using /usr/bin/cc (a thread loop workload and a JIT self-
modifying workload). Relying on external C compilers inside shell tests
frequently causes failures in continuous integration environments.

Create a built-in 'jitdump' workload and switch test_intel_pt.sh to use
'perf test -w thloop' and 'perf test -w jitdump'. Also add multi-
architecture compatibility without external C compiler dependencies, the
workload instruction arrays dynamically encode CHK_BYTE into opcodes
across x86, ARM32, ARM64, RISC-V, PowerPC, MIPS, LoongArch, and s390x.

Some minor include fixes for util/jitdump.h.

Subject: [PATCH 2816/5214] PCI: qcom: Initialize DWC MSI lock for
 firmware-managed ECAM hosts

A lockdep warning is observed during boot on a Qcom firmware-managed
platform:

  INFO: trying to register non-static key.
  The code is fine but needs lockdep annotation, or maybe
  you didn't initialize this object before use?
  turning off the locking correctness validator.
  ...
  Call trace:
   register_lock_class+0x128/0x4d8
   __lock_acquire+0x110/0x1db0
   lock_acquire+0x278/0x3d8
   _raw_spin_lock_irq+0x6c/0xc0
   dw_pcie_irq_domain_alloc+0x48/0x190
   irq_domain_alloc_irqs_parent+0x2c/0x48
   msi_domain_alloc+0x90/0x160
  ...

dw_pcie_irq_domain_alloc() takes pp->lock while allocating MSI
interrupts. pp->lock is normally initialized by dw_pcie_host_init(), but
Qcom firmware-managed hosts use the ECAM init path instead:

  pci_host_common_ecam_create()
    pci_ecam_create()
      qcom_pcie_ecam_host_init()
        dw_pcie_msi_host_init()
          dw_pcie_allocate_domains()

That path constructs a fresh struct dw_pcie_rp and calls
dw_pcie_msi_host_init() directly, without going through
dw_pcie_host_init(). As a result, pp->lock was not initialized, which
triggers the warning.

Initialize pp->lock in qcom_pcie_ecam_host_init() before registering the
MSI domains so the firmware-managed ECAM path matches the normal DWC host
initialization sequence.

Subject: [PATCH 2817/5214] dmaengine: sh: rz-dmac: Move interrupt request
 after everything is set up

Once the interrupt is requested, the interrupt handler may run immediately.
Since the IRQ handler can access channel->ch_base, which is initialized
only after requesting the IRQ, this may lead to invalid memory access.
Likewise, the IRQ thread may access uninitialized data (the ld_free,
ld_queue, and ld_active lists), which may also lead to issues.

Request the interrupts only after everything is set up. To keep the error
path simpler, use dmam_alloc_coherent() instead of dma_alloc_coherent().

Subject: [PATCH 2818/5214] dmaengine: sh: rz-dmac: Fix incorrect NULL check
 for list_first_entry()

list_first_entry() does not return NULL when the list is empty,
making the existing NULL check invalid. Use list_first_entry_or_null()
instead.

Subject: [PATCH 2825/5214] dmaengine: sh: rz-dmac: Use virt-dma APIs for
 channel descriptor processing

The driver used a mix of virt-dma APIs and driver specific logic to
process descriptors. It maintained three internal queues: ld_free,
ld_queue, and ld_active as follows:
- ld_free: stores the descriptors pre-allocated at probe time
- ld_queue: stores descriptors after they are taken from ld_free and
  prepared. At the same time, vchan_tx_prep() queues them to
  vc->desc_allocated. The vc->desc_allocated list is then checked in
  rz_dmac_issue_pending() and rz_dmac_irq_handler_thread() before
  starting a new transfer via rz_dmac_xfer_desc(). In turn,
  rz_dmac_xfer_desc() grabs the next descriptor from vc->desc_issued and
  submits it for transfer
- ld_active: stores the descriptors currently being transferred

The interrupt handler moved a completed descriptor to ld_free before
invoking its completion callback. Once returned to ld_free, the
descriptor can be reused to prepare a new transfer. In theory, this
means the descriptor could be re-prepared before its completion
callback is called.

Commit fully back the driver by the virt-dma APIs. With this, only ld_free
need to be kept to track how many free descriptors are available. This
is now done as follows:
- the prepare stage removes the first descriptor from the ld_free and
  prepares it
- the completion calls for it vc->desc_free() (rz_dmac_virt_desc_free())
  which re-adds the descriptor at the end of ld_free

With this, the critical areas in prepare callbacks were minimized to only
getting the descriptor from the ld_free list.

Introduce struct rz_dmac_chan::desc to keep track of the currently
transferred descriptor. It is cleared in rz_dmac_terminate_all(),
referenced from rz_dmac_issue_pending() to determine whether a new transfer
can be started, and from rz_dmac_irq_handler_thread() once a descriptor has
completed. Finally, the rz_dmac_device_synchronize() was updated with
vchan_synchronize() call to ensure the terminated descriptor is freed and
the tasklet is killed.

With this, residue computation is also simplified, as it can now be
handled entirely through the virt-dma APIs.

The spin_lock/unlock operations from rz_dmac_irq_handler_thread() were
replaced by guard as the final code after rework is simpler this way.

As subsequent commits will set the Link End bit on the last descriptor
of a transfer, rz_dmac_enable_hw() is also adjusted as part of the full
conversion to virt-dma APIs. It no longer checks the channel enable
status itself; instead, its callers verify whether the channel is
enabled and whether the previous transfer has completed before starting
a new one.

Subject: [PATCH 2826/5214] dmaengine: sh: rz-dmac: Refactor pause/resume code

Subsequent patches will add suspend/resume and cyclic DMA support to the
rz-dmac driver. This support needs to work on SoCs where power to most
components (including DMA) is turned off during system suspend. For this,
some channels (for example cyclic ones) may need to be paused and resumed
manually by the DMA driver during system suspend/resume.

Refactor the pause/resume support so the same code can be reused in the
system suspend/resume path.

Subject: [PATCH 2827/5214] dmaengine: sh: rz-dmac: Drop the update of
 channel->chctrl with CHCTRL_SETEN

The CHCTRL_SETEN bit is explicitly set in rz_dmac_enable_hw(). Updating
struct rz_dmac_chan::chctrl with this bit in
rz_dmac_prepare_desc_for_memcpy() and rz_dmac_prepare_descs_for_slave_sg()
is unnecessary in the current code base. Moreover, it conflicts with the
configuration sequence that will be used for cyclic DMA channels during
suspend to RAM. Cyclic DMA support will be introduced in subsequent
commits.

This is a preparatory commit for cyclic DMA suspend to RAM support.

Subject: [PATCH 2828/5214] dmaengine: sh: rz-dmac: Add cyclic DMA support

Add cyclic DMA support to the RZ DMAC driver. A per-channel status bit is
introduced to mark cyclic channels and is set during the DMA prepare
callback. The IRQ handler checks this status bit and calls
vchan_cyclic_callback() accordingly.

Subject: [PATCH 2830/5214] dmaengine: sh: rz-dmac: Add runtime PM support

Protect the driver exposed APIs with runtime PM suspend/resume calls
before accessing HW registers. As the current driver leaves runtime PM
enabled in probe, the purpose of the changes in this patch is to avoid
accessing HW registers after a failed system suspend leaves the runtime
PM state of the device improperly reinitialized.

In that case, the driver remains bound to the device, the APIs are still
exposed, and any access to HW registers without runtime resuming the
device may lead to synchronous aborts.

To avoid leaking resources in case of runtime PM failures, save the error
code returned by PM_RUNTIME_ACQUIRE_ERR() in rz_dmac_terminate_all() and
return it only at the end of the function to allow the cleanup code to
run. A similar approach is used in rz_dmac_free_chan_resources().

Because some exposed APIs (e.g. ->device_terminate_all()) may be called
from atomic context according to the documentation, mark the DMA device as
pm_runtime_irq_safe().

This patch prepares the driver for suspend-to-RAM support.

Subject: [PATCH 2831/5214] dmaengine: sh: rz-dmac: Add suspend to RAM support

The Renesas RZ/G3S SoC supports a power saving mode in which power to most
of the SoC components is turned off, including the DMA IP. Add suspend to
RAM support to save and restore the DMA IP registers.

Cyclic DMA channels require special handling. Since they can be paused and
resumed during system suspend/resume, the driver restores additional
registers for these channels during the system resume phase. If a channel
was not explicitly paused during suspend, the driver ensures that it is

Subject: [PATCH 2833/5214] ASoC: renesas: rz-ssi: Use generic PCM dmaengine
 APIs

On Renesas RZ/G2L and RZ/G3S SoCs (where this was tested), captured audio
files occasionally contained random spikes when viewed with a tool such
as Audacity. These spikes were also audible as popping noises.

Using cyclic DMA resolves this issue. The driver was reworked to use the
existing support provided by the generic PCM dmaengine APIs. In addition
to eliminating the random spikes, the following issues were addressed:
- blank periods at the beginning of recorded files, which occurred
  intermittently, are no longer present
- no overruns or underruns were observed when continuously recording
  short audio files (e.g. 5 seconds long) in a loop
- concurrency issues in the SSI driver when enqueuing DMA requests were
  eliminated; previously, DMA requests could be prepared and submitted
  both from the DMA completion callback and the interrupt handler, which
  led to crashes after several hours of testing
- the SSI driver logic is simplified
- the number of generated interrupts is reduced by approximately 250%

In the SSI platform driver probe function, the following changes were
made:
- the driver-specific DMA configuration was removed in favor of the
  generic PCM dmaengine APIs. As a result, explicit cleanup goto labels
  are no longer required and the driver remove callback was dropped,
  since resource management is now handled via devres helpers
- special handling was added for IP variants operating in half-duplex
  mode, where the DMA channel name in the device tree is "rt"; this DMA
  channel name is taken into account and passed to the generic PCM
  dmaengine configuration data

All code previously responsible for preparing and completing DMA
transfers was removed, as this functionality is now handled entirely by
the generic PCM dmaengine APIs.

Since DMA channels must be paused and resumed during recovery paths
(overruns and underruns reported by the hardware), the DMA channel
references are stored in rz_ssi_hw_params().

The logic in rz_ssi_is_dma_enabled() was updated to reflect that the
driver no longer manages DMA transfers directly.

To avoid software reported underruns (e.g. when running aplay during
consecutive suspend/resume cycles, or when the CPU is nearly 100%
loaded), rz_ssi_pcm_hardware.buffer_bytes_max was increased to 192K.
At the same time, rz_ssi_pcm_hardware.period_bytes_max was set to 48K
to reduce interrupt overhead.

Finally, rz_ssi_stream_is_play() was removed, as it had only a single
remaining user after this rework, and its logic was inlined at the call
site.

Subject: [PATCH 2834/5214] dmaengine: sh: rz-dmac: Set the Link End (LE) bit
 on the last descriptor

On an RZ/G2L-based system, it has been observed that when the DMA channels
for all enabled IPs are active (TX and RX for one serial IP, TX and RX for
one audio IP, and TX and RX for one SPI IP), shortly after all of them are
started, the system can become irrecoverably blocked. In one debug session
the system did not block, and the DMA HW registers were inspected. It was
found that the DER (Descriptor Error) bit in the CHSTAT register for one of
the SPI DMA channels was set.

According to the RZ/G2L HW Manual, Rev. 1.30, chapter 14.4.7 Channel
Status Register n/nS (CHSTAT_n/nS), description of the DER bit, the DER
bit is set when the LV (Link Valid) value loaded with a descriptor in link
mode is 0. This means that the DMA engine has loaded an invalid
descriptor (as defined in Table 14.14, Header Area, of the same manual).

The same chapter states that when a descriptor error occurs, the transfer
is stopped, but no DMA error interrupt is generated.

Set the LE bit on the last descriptor of a transfer. This informs the DMA
engine that this is the final descriptor for the transfer.

Subject: [PATCH 2835/5214] cxl/memdev: Hold memdev lock during memdev poison
 injection/clear

cxl_dpa_to_region() assumes that it is running a context where it is not
racing changes to "cxlmd->dev.driver". Acquire the memdev device lock in
the debugfs entry points to preclude debugfs usage racing cxl_mem driver
detach.

Subject: [PATCH 2836/5214] cxl/region: Validate partition index before array
 access

construct_region() reads cxled->part and uses it to index
cxlds->part[] without checking for a negative value. If the
partition was never resolved, part remains at its initial value
of -1, causing an out-of-bounds array access.

Add a guard to return -EBUSY when part is negative.

The check was dropped during a merge.

Subject: [PATCH 2837/5214] cxl/test: Enforce PMD alignment for volatile mock
 regions

cxl_test allocates synthetic CFMWS HPA windows from a gen_pool with
SZ_256M alignment. On arm64 with CONFIG_ARM64_64K_PAGES=y and
CONFIG_PGTABLE_LEVELS=3, PMD_SIZE is 512M, so every CXL region carved
from a volatile window inherits a non-PMD-aligned start, and
cxl_dax_region_probe() -> alloc_dax_region() fails:

"""
    cxl_dax_region dax_region1: probe with driver cxl_dax_region failed
                                with error -12
"""

Enforce that every volatile mock CFMWS is PMD-aligned in both start and
size

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a driver for charger controllers found in certain Samsung S2M series
PMICs. The driver has very basic support for the device, with only
charger online reporting working, and USB 2.0 device negotiations
working.

The driver includes initial support for the S2MU005 PMIC charger.

Subject: [PATCH 2842/5214] rpmsg: char: Fix use-after-free on probe error path

rpmsg_chrdev_probe() stores the newly allocated eptdev in the default
endpoint's priv pointer before calling rpmsg_chrdev_eptdev_add(). If
rpmsg_chrdev_eptdev_add() then fails, its error path frees eptdev while
the default endpoint may still dispatch callbacks with the stale priv
pointer.

Avoid publishing eptdev through the default endpoint until
rpmsg_chrdev_eptdev_add() succeeds. Messages received before the priv
pointer is published should be ignored by rpmsg_ept_cb(). Flow-control
updates can hit rpmsg_ept_flow_cb() in the same window, so make both
callbacks return success when priv is NULL.

Subject: [PATCH 2844/5214] perf lock contention: Allow 'mmap_lock' in
 -L/--lock-filter

The -L/--lock-filter option is to specify target locks by name or
address.  It's basically for global locks where name or address is known
and fixed.  But 'mmap_lock' is a per-process lock so it cannot be used
for the -L option.

  $ sudo perf lock con -ab -L mmap_lock
  ignore unknown symbol: mmap_lock
  libbpf: map 'addr_filter': failed to create: -EINVAL
  libbpf: failed to load BPF skeleton 'lock_contention_bpf': -EINVAL
  Failed to load lock-contention BPF skeleton
  lock contention BPF setup failed

However, it's still a common source of contention especially in a large
process so we want to use it for the -L/--lock-filter option.  As there
is check_lock_type() to check mmap_lock at runtime, let's used it to
filter mmap_locks as a special case.

Of course, this only works with -b/--use-bpf option.

  $ sudo perf lock con -b -L mmap_lock -- perf bench mem mmap -f demand -t 2
  # Running 'mem/mmap' benchmark:
  # function 'demand' (Demand loaded mmap())
  # Copying 1MB bytes ...

         2.679184 GB/sec/thread	( +-   1.78% )

Subject: [PATCH 2845/5214] perf data ctf: replace libbabeltrace with
 babeltrace2-ctf-writer

The 1.x branch of Babeltrace has been superseded by 2.x in 2020 and has
been unmaintained since 2022, efforts have started to remove it from
popular distributions.

Babeltrace 2.x offers a very similar 'ctf-writer' library that can be used
with minimal changes for the '--to-ctf' feature and has been packaged
since Debian 11 and Fedora 32.

This patch replaces the 'libbabeltrace' build feature with
'babeltrace2-ctf-writer' using pkgconfig detection, adjusts the naming of
the public headers and applies minor API cleanups.

There is no changes to the output ctf traces, the ctf-writer API still
implements version 1.8 of the CTF specification that can be read by
either Babeltrace 1 / 2 or any CTF compliant reader.

Also remove some ifdefs in the cli option parsing to allow printing the
helpful error message with '--to-ctf' when built without babeltrace2.

Subject: [PATCH 2846/5214] perf pmu: Recognize 'default_core' as a core PMU
 and document matching

The is_pmu_core function checks if a PMU name corresponds to a core
CPU PMU. However, it currently fails to recognize "default_core" as
a core PMU.

When "default_core" is used, the PMU scanning fallback in pmus.c
scans the "other_pmus" list. This scan is slow and always misses because
"default_core" is a core PMU, leading to unnecessary overhead.

Update is_pmu_core to recognize "default_core" directly. Additionally,
document the different matching approaches (exact name for x86/s390,
sysfs-based cpus file check for ARM/hybrid) to clarify how core PMUs are
classified.

Also, explicitly treat "default_core" as `all_pmus` in `setup_metric_events()`
to preserve the original metric resolution behavior for this pseudo-PMU.

Subject: [PATCH 2847/5214] perf lock contention: Enable end-timestamp
 accounting for cgroup aggregation

update_lock_stat() handles lock contentions that start but never reach a
contention_end event (e.g., locks still held when profiling stops), but
previously treated LOCK_AGGR_CGROUP as a no-op due to missing cgroup
context in userspace.

Fix this by adding a cgroup_id field to struct tstamp_data, recording it
at contention_begin using get_current_cgroup_id() when aggr_mode is
LOCK_AGGR_CGROUP. Capturing it at contention_begin is semantically
correct, the contention cost is incurred by the task that had to wait,
not by whatever task happens to be running at contention_end. It is also
preferable from a performance standpoint, as contention_end runs just
before the task enters the critical section.

Update contention_end to use pelem->cgroup_id instead of calling
get_current_cgroup_id() dynamically, ensuring both complete and
incomplete contention events attribute the wait time to the cgroup at
wait-start time consistently.

Subject: [PATCH 2848/5214] perf tools: Guard test_bit from out-of-bounds
 sample CPU

When PERF_SAMPLE_CPU is absent from a perf.data file, sample->cpu is
initialized to (u32)-1 by evsel__parse_sample().  Five call sites pass
this value directly to test_bit(sample->cpu, cpu_bitmap), reading
massively out of bounds past the DECLARE_BITMAP(..., MAX_NR_CPUS)
allocation of 4096 bits.

Add a sample->cpu >= MAX_NR_CPUS guard before each test_bit() call,
matching the existing safe pattern in builtin-kwork.c.  This catches
both the (u32)-1 sentinel and any corrupted CPU value exceeding the
bitmap size.

Subject: [PATCH 2850/5214] perf sched: Fix NULL dereference in
 latency_runtime_event

latency_runtime_event() passes the return value of
machine__findnew_thread() directly to thread_atoms_search() at line
1216, before checking for NULL at line 1220.  thread_atoms_search()
calls pid_cmp() which dereferences the thread pointer via
thread__tid(), causing a NULL pointer dereference if the allocation
fails.

All other callers of thread_atoms_search() in this file
(latency_switch_event, latency_wakeup_event,
latency_migrate_task_event) correctly check for NULL first.

Move the atoms assignment after the NULL check to match the pattern
used by the other callers.

Subject: [PATCH 2851/5214] perf sched: Fix comp_cpus heap overflow with
 cross-machine recordings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

setup_map_cpus() allocates comp_cpus based on
sysconf(_SC_NPROCESSORS_CONF), the host machine's CPU count.  But
map_switch_event() indexes comp_cpus using cpus_nr derived from
bitmap_weight(comp_cpus_mask, MAX_CPUS), where comp_cpus_mask is
declared as DECLARE_BITMAP(..., MAX_CPUS) with MAX_CPUS=4096.

When analyzing a perf.data recording from a machine with more CPUs
than the analysis host (e.g. 128-CPU server recording analyzed on an
8-CPU laptop), cpus_nr exceeds the allocation size, causing a heap
buffer overflow.

Also fix a type mismatch: comp_cpus is 'struct perf_cpu *' (2 bytes
per element) but was allocated with sizeof(int) (4 bytes per element).

Allocate comp_cpus with MAX_CPUS entries using the correct element
size, matching the comp_cpus_mask bitmap bounds.  Remove the
sysconf(_SC_NPROCESSORS_CONF) initialization of max_cpu — its only
consumer was the comp_cpus allocation, and max_cpu is dynamically
updated from the recording's events during processing.  Fix the
non-compact path to use max_cpu.cpu + 1 as cpus_nr, converting from
0-based index to count — sysconf() returned a count which masked
this off-by-one.

Subject: [PATCH 2853/5214] mm/page_alloc: fix defrag_mode for non-reclaimable
 allocations

When defrag_mode is enabled, ALLOC_NOFRAGMENT is enforced to prevent
migratetype fallbacks and keep pageblocks clean.  The allocator relies on
reclaim and compaction to free pages of the correct type before allowing
fallback as a last resort.

However, non-reclaimable allocations such as GFP_ATOMIC cannot invoke
direct reclaim or compaction.  With defrag_mode=1, these allocations hit
the !can_direct_reclaim bailout in __alloc_pages_slowpath() with
ALLOC_NOFRAGMENT still set, and fail without ever attempting a fallback.

This causes a large number of SLUB allocation failures for
skbuff_head_cache under network-heavy workloads, despite free memory being
available in other migratetype freelists.

We observed it on a few of the Meta workloads that adopted
defrag_mode=1.

For the service under load there were 85509 SLUB allocation failures
messages in dmesg within 2 hours.  All of them are GFP_ATOMIC
allocations for skbuff_head_cache, despite free pages being available
in other migratetype freelists (~13 GB free).

Since it is networking path from the practical point of view, this
means dropped packets, failed RPC requests, tail latency spikes and
overall service degradation.

Clear ALLOC_NOFRAGMENT and retry for allocations that request kswapd
reclaim but cannot do direct reclaim themselves (GFP_ATOMIC).  Purely
speculative allocations like GFP_TRANSHUGE_LIGHT that don't set
__GFP_KSWAPD_RECLAIM are left to fail, since they have reasonable
fallbacks and should not cause fragmentation.

Subject: [PATCH 2855/5214] drivers/char/mem: eliminate unnecessary use of
 success_hook

Patch series "remove mmap_action success, error hooks", v3.

The mmap_action->success_hook was a strange beast added to enable code
which appeared to absolutely require access to a VMA pointer to work
correctly.

Primarily this was for hugetlb, however a different approach will be taken
there, as clearly more work is required to figure out a sensible way of
converting hugetlb to use mmap_prepare.

The other user was the memory char driver, specifically /dev/zero which
has the unusual property of explicitly setting file-backed VMAs anonymous.

Providing the success hook was always foolish, as it allowed drivers a way
to workaround the restriction that they should not access a pointer to a
not-yet-correctly-initialised VMA - which defeats the purpose of the
mmap_prepare work.

We can achieve the same thing in memory char driver without needing the
success hook, so this series removes that, then removes the success hook
altogether.

The error hook is also unnecessary - the motivation for this was for
functions which need to override the error code when performing an mmap
action in order to avoid breaking userspace.

We can achieve this by just providing a field for the error code.  Doing
this means we don't have to worry about the hook doing anything odd.

We also add a check to ensure the error code is in fact valid.

Again the memory char driver is the only current user of this, so this
series updates it to use that.

After this change mmap_action has no custom hooks at all, which seems
rather more cromulent than before.


This patch (of 3):

/dev/zero, uniquely, marks memory mapped there as anonymous.  This is
currently achieved using the mmap_action->success_hook.

However this hook circumvents the abstraction of VMA initialisation so
it's preferable to do things a different way.

To achieve this, this patch firstly defaults the VMA descriptor's vm_ops
field to the dummy VMA operations, which is what file-backed VMAs default
this field to.

That way, we can detect whether a driver sets this field to NULL in order
to mark it anonymous.

We then introduce vma_desc_set_anonymous() to do this explicitly, and
invoke it in mmap_zero_prepare().

This way, any driver which does not explicitly set desc->vm_ops, retains
the dummy vm_ops as they would previously.

We also update set_vma_user_defined_fields() to make clear that we are
either setting vma->vm_ops to what is provided by the driver (or
defaulting to dummy_vm_ops if not set), or setting the VMA anonymous.

This lays the groundwork for removing the success hook.

Subject: [PATCH 2856/5214] mm/vma: remove mmap_action->success_hook

This hook was introduced to work around code that seemed to absolutely
require access to a VMA pointer upon mmap().

However, providing this hook leaves a backdoor to drivers getting access
to the very thing mmap_prepare eliminates - a pointer to the VMA.

Let's solve this contradiction by removing it.  The key intended user was
hugetlb, however it seems that the best course now is to avoid allowing
all drivers the ability to work around mmap_prepare, and find a different
solution there.

Subject: [PATCH 2857/5214] mm/vma: eliminate mmap_action->error_hook,
 introduce error_override

Rather than providing a hook, simplify things by providing the ability to
override mmap action errors.  This allows us to more carefully validate
the value provided and thus ensure only a valid error code is specified,
and simplifies the interface.

This way, we eliminate all hooks but mmap_prepare and allow only mmap
actions to be specified (which core mm controls).

This significantly improves robustness and eliminates any unnecessary code
duplication in driver mmap hooks.

We also update the /dev/mem logic (the only user) to use
mmap_action->error_override instead.

Subject: [PATCH 2858/5214] mm/damon/core: safely handle no region case in
 damon_set_regions()

Patch series "mm/damon: minor improvements for code readability and tests".

Implement minor improvements on code readability and tests for DAMON.

First seven patches are for DAMON code readability and resulting
maintenance.  Patches 1 and 2 make damon_set_regions() safer and easier to
read.  Patches 3 and 4 remove fragmented DAMON API use cases.  Patches 5-7
hides unused core functions that are unnecessarily exposed to API callers.

The following seven patches are for DAMON tests improvement.  Patches 8
and 9 adds and removes DAMON_DEBUG_SANITY verifications to ensure
reasonable test coverage without too high overhead.  Patch 10 adds a new
kunit test for damon_set_regions().  Patch 11 makes sysfs.py selftest more
gracefully finishes under test failures.  Patches 12-13 adds simple
sysfs.sh test cases for the monitoring intervals goal directory, the
addr_unit file and the pause file.


This patch (of 14):

damon_set_regions() calls damon_first_region() regardless of the number of
DAMON regions in a given DAMON target.  damon_first_region() internally
uses list_first_entry(), which clearly documents the list is expected to
be not empty.  Due to the internal implementation of the macro,
damon_set_regions() is safe for now.  But the internal implementation of
the macro can be changed in future.  Refactor the function to explicitly
and safely handle the empty region list case without depending on the
internal implementation.

No behavioral change is intended.

 damon_set_regions()

damon_set_regions() assumes the DAMON region iterator is referencing the
last region after the region iteration loop is completed.  The code is
indeed implemented in the way, but that is not a documented safe behavior.
Hence it is unreliable and difficult to read.  Cleanup the code to avoid
the case.

No behavioral change is intended.

Subject: [PATCH 2860/5214] samples/damon/mtier: replace damon_add_region()
 with damon_set_regions()

mtier DAMON sample module and DAMON virtual address operation set (vaddr)
unit tests are using damon_add_region() for setup of DAMON monitoring
target region boundaries setup.  But, damon_set_regions() is designed for
exactly the purpose.  All other DAMON API callers use the function for the
purpose.  Replace damon_add_region() usage in mtier sample module with
damon_set_regions(), for unifying the use case and reducing the
maintenance cost.

Subject: [PATCH 2866/5214] mm/damon/core: remove damon_verify_nr_regions()

When CONFIG_DAMON_DEBUG_SANITY is enabled, damon_verify_nr_regions() is
called for each damon_nr_regions() invocation.  damon_veify_nr_regions()
iterates all regions.  damon_nr_regions() is called for each region in
kdamond_reset_aggregated() and damos_apply_scheme().  Hence it imposes
O(n**2) overhead where n is the number of regions.

Though the verification is enabled only under DAMON_DEBUG_SANITY, which is
not for production use cases, it could be too high overhead.  Meanwhile,
damon_verify_ctx() is doing the damon_nr_regions() test.  Because
damon_verify_ctx() is called for each kdamond_call(), the test coverage
from damon_verify_ctx() could be sufficient.  Remove damon_nr_regions()
verification.

Subject: [PATCH 2868/5214] selftests/damon/sysfs.py: stop kdamonds before
 failing

When an assertion is failed, sysfs.py DAMON selftest immediately exits the
test program leaving the DAMON running behind.  Many of the following
tests need to start DAMON on their own.  But because DAMON that was
started by sysfs.py is still running, those start attempts fail, and the
tests are failed or skipped.  Update sysfs.py to stop DAMON before exiting
the test program due to the assertion failure.

Patch series "mm/damon: fix macro arguments and clarify quota goals doc",
v2.


This patch (of 2):

The DAMON iterator macros do not wrap their pointer arguments with
parentheses.  This can cause build failures when the argument is a complex
expression due to operator precedence issues.

Add missing parentheses around the arguments in the following macros
to prevent potential build failures:
- damon_for_each_region()
- damon_for_each_region_from()
- damon_for_each_region_safe()
- damos_for_each_quota_goal()

 current_value of quota goals

The sysfs interface for DAMON quota goals includes a `current_value` file.
This file is not updated by the kernel and only serves to receive user
input.

Clarify in the documentation that the kernel does not update
`current_value`, and that reading it only has meaning when `target_metric`
is set to `user_input`.

While at it, fix missing commas in the goal files list.

Subject: [PATCH 2874/5214] mm/damon/core: trace esz at first setup

DAMON traces effective size quota from the second update, only if a change
has been made by the update.  Tracing only changed updates was an
intentional decision to avoid unnecessary same value tracing.  Always
skipping the first value is just an unintended mistake.

The mistake makes the tracepoint based investigation incomplete, because
the first effective size quota is never traced.  It is not a big issue
when the 'consist' quota tuner is used, because it keeps changing the
quota in the usual setup.

However, when the 'temporal' tuner is used, the quota value is not changed
before the goal achievement status is completely changed.  For example, if
the DAMOS scheme is started with an under-achieved goal, the quota is set
to the maximum value, and kept the same value until the goal is achieved.
Because DAMON skips the first value, the user cannot know what effective
quota the current scheme is using.  Only after the goal is achieved, the
effective quota is changed to zero, and traced.

Unconditionally trace the initial quota value to fix this problem.

Note that the 'temporal' quota tuner was introduced by commit af738a6a00c1
("mm/damon/core: introduce DAMOS_QUOTA_GOAL_TUNER_TEMPORAL"), which was
added to 7.1-rc1.  But even with the 'consist' quota tuner, the tracing is
unintentionally incomplete.  Hence this commit marks the introduction of
the trace event as the broken commit.

Subject: [PATCH 2876/5214] mm/mglru: use folio_mark_accessed to replace
 folio_set_active

MGLRU gives high priority to folios mapped in page tables.  As a result,
folio_set_active() is invoked for all folios read during page faults.  In
practice, however, readahead can bring in many folios that are never
accessed via page tables.

A previous attempt by Lei Liu proposed introducing a separate LRU for
readahead[1] to make readahead pages easier to reclaim, but that approach
is likely over-engineered.

Before commit 4d5d14a01e2c ("mm/mglru: rework workingset protection"),
folios with PG_active were always placed in the youngest generation,
leading to over-protection and increased refaults.  After that commit,
PG_active folios are placed in the second youngest generation, which is
still too optimistic given the presence of readahead.  In contrast, the
classic active/inactive scheme is more conservative.

This patch switches to using folio_mark_accessed() and
begins prefaulted file folios from the second oldest
generation instead of active generations.
We should also adjust the following accordingly:
- WORKINGSET_ACTIVATE: aligned with setting active for refaulted workingset
  folios;
- lru_gen_folio_seq(): place (pre)faulted file folios into the second
oldest generation;
- promote second-scanned folios to workingset in
folio_check_references(): we now have to depend on
folio_lru_refs() > 1, since we previously relied on PG_referenced
being set during the first scan, but PG_referenced is now set
earlier.

On x86, running a kernel build inside a memcg with a 1GB memory
limit using 20 threads.

Subject: [PATCH 2878/5214] userfaultfd: merge fs/userfaultfd.c into
 mm/userfaultfd.c

Patch series "userfaultfd: merge fs/userfaultfd.c into mm/userfaultfd.c",
v3.

These patches merge fs/userfaultfd.c into mm/userfaultfd.c and make
functions used only inside mm/userfaultfd.c static.


This patch (of 2):

Historically userfaultfd implementation has been split between
fs/userfaultfd.c and mm/userfaultfd.c.

The mm/ part implemented memory management operations, while the fs/ part
implemented file descriptor handling and called into the mm/ part for the
actual memory management work.

This separation is quite artificial and fs/userfaultfd.c does not seem to
belong to fs/ because it's only a user if vfs APIs and like for other
users, for example, memfd and secretmem, the file descriptor handling
could live in mm/ as well.

"Append" fs/userfaultfd.c to mm/userfaultfd and update fs/Makefile and
MAINTAINERS accordingly.

No intended functional changes.

Subject: [PATCH 2879/5214] userfaultfd: make functions that are not used
 outside uffd static

After merging fs/userfaultfd.c into mm/userfaultfd.c, several functions
that were previously shared between the two files are now only used within
mm/userfaultfd.c.

Make them static and remove their declarations from
include/linux/userfaultfd_k.h.

Subject: [PATCH 2880/5214] mm/mglru: consolidate common code for retrieving
 evictable size

Patch series "mm/mglru: improve reclaim loop and dirty folio", v7.

This series cleans up and slightly improves MGLRU's reclaim loop and dirty
writeback handling.  As a result, we can see an up to ~30% increase in
some workloads like MongoDB with YCSB and a huge decrease in file refault,
no swap involved.  Other common benchmarks have no regression, and LOC is
reduced, with less unexpected OOM, too.

Some of the problems were found in our production environment, and others
were mostly exposed while stress testing during the development of the
LSM/MM/BPF topic on improving MGLRU [1].  This series cleans up the code
base and fixes several performance issues, preparing for further work.

MGLRU's reclaim loop is a bit complex, and hence these problems are
somehow related to each other.  The aging, scan number calculation, and
reclaim loop are coupled together, and the dirty folio handling logic is
quite different, making the reclaim loop hard to follow and the dirty
flush ineffective.

This series slightly cleans up and improves these issues using a scan
budget by calculating the number of folios to scan at the beginning of the
loop, and decouples aging from the reclaim calculation helpers.  Then,
move the dirty flush logic inside the reclaim loop so it can kick in more
effectively.  These issues are somehow related, and this series handles
them and improves MGLRU reclaim in many ways.

Test results: All tests are done on a 48c96t NUMA machine with 2 nodes and
a 128G memory machine using NVME as storage.  Classical (non-MGLRU) LRU
numbers are included as "MGLRU disabled" for each benchmark below; see [8]
and [9] for the longer write-up.

MongoDB
=======
Running YCSB workloadb [2] (recordcount:20000000 operationcount:6000000,
threads:32), which does 95% read and 5% update to generate mixed read and
dirty writeback.  MongoDB is set up in a 10G cgroup using Docker, and the
WiredTiger cache size is set to 4.5G, using NVME as storage.  This is
close to the case we observed regressing in our production environment:
mixed read and writeback pressure, so it is a practical case for
evaluation.

Not using SWAP.  The intent is to isolate the file LRU writeback path.
Enabling SWAP would just add noise from anonymous reclaim.

MGLRU Before:
Throughput(ops/sec): 60653.502655
workingset_refault_file 12904916
pgpgin 165366622
pgpgout 5219588

MGLRU After:
Throughput(ops/sec): 82384.354760 (+35.8%, higher is better)
workingset_refault_file 7128285   (-44.7%, lower is better)
pgpgin 113170693                  (-31.5%, lower is better)
pgpgout 5639724

MGLRU Disabled:
Throughput(ops/sec): 93713.640901
workingset_refault_file 15013443
pgpgin 85365614
pgpgout 5866508

We can see a significant performance improvement after this series.  The
test is done on NVME and the performance gap would be even larger for slow
devices, such as HDD or network storage.  We observed over 100% gain for
some workloads with slow IO.

Note, classical LRU is still faster for this benchmark, MGLRU may catch up
later with further work [7].

Chrome & Node.js [3]
====================
Using Yu Zhao's test script [3], testing on a x86_64 NUMA machine with 2
nodes and 128G memory, using 256G ZRAM as swap and spawn 32 memcg 64
workers.  Many memcgs each applying roughly equal pressure exercises the
LRU's ability to detect/protect each tenant's working set and to balance
reclamation fairly between tenants, which makes this a meaningful test for
the reclaim mechanism.

Fairness is reported via Jain's fairness index (1.0 means all tenants get
exactly equal allocation, lower is worse).  Under equal pressure, all
memcgs should make roughly equal forward progress.  See [8] for the longer
rationale and per-memcg breakdown.

Reclaim is still fair and effective, total requests number seems slightly
better.

OOM issue with aging and throttling
===================================
For the throttling OOM issue, it can be easily reproduced using dd and
cgroup limit as demonstrated and fixed by a later patch in this series.

The aging OOM is a bit tricky, a specific reproducer can be used to
simulate what we encountered in production environment [4]: Spawns
multiple workers that keep reading the given file using mmap, and pauses
for 120ms after one file read batch.  It also spawns another set of
workers that keep allocating and freeing a given size of anonymous memory.
The total memory size exceeds the memory limit (eg.  14G anon + 8G file,
which is 22G vs a 16G memcg limit).

- MGLRU disabled:
  Finished 128 iterations.

- MGLRU enabled:
  OOM with following info after about ~10-20 iterations:
    [   62.624130] file_anon_mix_p invoked oom-killer: gfp_mask=0xcc0(GFP_KERNEL), order=0, oom_score_adj=0
    [   62.624999] memory: usage 16777216kB, limit 16777216kB, failcnt 24460
    [   62.640200] swap: usage 0kB, limit 9007199254740988kB, failcnt 0
    [   62.640823] Memory cgroup stats for /demo:
    [   62.641017] anon 10604879872
    [   62.641941] file 6574858240

  OOM occurs despite there being still evictable file folios.

- MGLRU enabled after this series:
  Finished 128 iterations.

Worth noting there is another OOM related issue reported in V1 of this
series, which is tested and looking OK now [5].

MySQL:
======

Testing with innodb_buffer_pool_size=26106127360, in a 2G memcg, using
ZRAM as swap and test command:

sysbench /usr/share/sysbench/oltp_read_only.lua --mysql-db=sb \
  --tables=48 --table-size=2000000 --threads=48 --time=600 run

A 24G InnoDB buffer pool inside a 2G memcg with ZRAM as swap forces
aggressive eviction of cached database anon pages, which exercises the
LRU's hot page detection and the eviction path under swap pressure.  The
workload is practical, and the pressure is higher than what we usually see
in production but it is intended to expose the extreme case.

MGLRU before:   17313.688333 tps
MGLRU after:    17286.195000 tps
MGLRU disabled: 16245.330000 tps

Seems only noise level changes, no regression.

FIO:
====
Testing with the following command, where /mnt/ramdisk is a 64G EXT4
ramdisk, each test file is 3G, in a 10G memcg, 6 test run each:

fio --directory=/mnt/ramdisk --filename_format='test.$jobnum.img' \
  --name=cached --numjobs=16 --size=3072M --buffered=1 --ioengine=mmap \
  --rw=randread --norandommap --time_based \
  --ramp_time=1m --runtime=5m --group_reporting

Random buffered mmap read on a ramdisk strips out storage variance and
stresses purely the LRU's ability to evict and recycle the page cache
under heavy random read pressure.

MGLRU before:      9033.91 MB/s
MGLRU after:       9065.72 MB/s
MGLRU disabled:    8254.54 MB/s

Also seem only noise level changes and no regression or slightly better.

Build kernel:
=============
Build kernel test using ZRAM as swap, kernel source on tmpfs, in a memcg
with memory.max=3G, using make -j96 and defconfig, measuring system time,
6 test run each.  Building the kernel is a classical mixed anon + file
workload (lots of small file reads/writes plus parallel anon allocations
from cc/ld) and is representative of many real compilation jobs.

MGLRU before:     2823.13s
MGLRU after:      2801.26s
MGLRU disabled:   5023.50s

Also seem only noise level changes, no regression or very slightly better.

Android:
========
Xinyu reported a performance gain on Android, too, with this series.  The
test consisted of cold-starting multiple applications sequentially under
moderate system load [6]; this is a real Android user-visible scenario,
dominated by the LRU's ability to keep the right working set resident and
re-fault launch-critical pages quickly.

Before:
Launch Time Summary (all apps, all runs)
  Mean 868.0ms
  P50 888.0ms
  P90 1274.2ms
  P95 1399.0ms

After:
Launch Time Summary (all apps, all runs)
  Mean 850.5ms (-2.07%)
  P50 861.5ms  (-3.04%)
  P90 1179.0ms (-8.05%)
  P95 1228.0ms (-12.2%)


This patch (of 15):

Merge commonly used code for counting evictable folios in a lruvec.

No behavior change.

Subject: [PATCH 2882/5214] mm/mglru: relocate the LRU scan batch limit to
 callers

Same as active / inactive LRU, MGLRU isolates and scans folios in batches.
The batch split is done hidden deep in the helper, which makes the code
harder to follow.  The helper's arguments are also confusing since callers
usually request more folios than the batch size, so the helper almost
never processes the full requested amount.

Move the batch splitting into the top loop to make it cleaner, there
should be no behavior change.

Subject: [PATCH 2883/5214] mm/mglru: restructure the reclaim loop

The current loop will calculate the scan number on each iteration.  The
number of folios to scan is based on the LRU length, with some unclear
behaviors, e.g, the scan number is only shifted by reclaim priority when
aging is not needed or when at the default priority, and it couples the
number calculation with aging and rotation.

Adjust, simplify it, and decouple aging and rotation.  Just calculate the
scan number for once at the beginning of the reclaim, always respect the
reclaim priority, and make the aging and rotation more explicit.

This slightly changes how aging and offline memcg reclaim works:
Previously, aging was skipped at DEF_PRIORITY even when eviction was no
longer possible, so the reclaimer wasted an iteration until the priority
escalated.  Now aging runs immediately whenever it is needed to make
progress; the DEF_PRIORITY skip only applies when eviction is still
viable.  This may avoid wasted iterations that over-reclaim slab and break
reclaim balance in multi-cgroup setups.

Similar for offline memcg.  Previously, offline memcg wouldn't be aged
unless it didn't have any evictable folios.  Now, we might age it if it
has only 3 generations, which should be fine.  On one hand, offline memcg
might still hold long-term folios, and in fact, a long-existing offline
memcg must be pinned by some long-term folios like shmem.  These folios
might be used by other memcg, so aging them as ordinary memcg seems
correct.  Besides, aging enables further reclaim of an offlined memcg,
which will certainly happen if we keep shrinking it.  And offline memcg
might soon be no longer an issue with reparenting.

Overall, the memcg LRU rotation, as described in mmzone.h, remains the
same.

Note that because the scan budget is now pinned at loop entry, tiny lruvec
might skip this reclaim pass, also skipping aging, which could be
beneficial as aging is not helpful since it will still be un-reclaimable
after aging.  Reclaim will go on as usual once priority escalates.

Subject: [PATCH 2884/5214] mm/mglru: scan and count the exact number of folios

Make the scan helpers return the exact number of folios being scanned or
isolated.  Since the reclaim loop now has a natural scan budget that
controls the scan progress, returning the scan number and consuming the
budget makes the scan more accurate and easier to follow.

The number of scanned folios for each iteration is always larger than 0,
unless the reclaim must stop for a forced aging, so there is no more need
for any special handling when there is no progress made:

- `return isolated || !remaining ?  scanned : 0` in scan_folios: both
  the function and the call now just return the exact scan count, combined
  with the scan budget introduced in the previous commit to avoid livelock
  or under scan.

- `scanned += try_to_inc_min_seq` in evict_folios: adding a bool as a
  scan count was kind of confusing and no longer needed, as scan number
  should never be zero as long as there are still evictable gens.  We may
  encounter a empty old gen that returns 0 scan count, to avoid that, do a
  try_to_inc_min_seq before toisolation which have slight to none overhead
  in most cases.

- `evictable_min_seq + MIN_NR_GENS > max_seq` guard in evict_folios: the
  per-type get_nr_gens == MIN_NR_GENS check in scan_folios naturally
  returns 0 when only two gens remain and breaks the loop.

Also change try_to_inc_min_seq to return void, as its return value is no
longer used by any caller.  Call it before isolate_folios to flush any
empty gens left by external folio freeing, and again after isolate_folios
when scanning moved or protected folios may have emptied the oldest gen.

The scan still stops if only two gens are left, as the scan number will be
zero.  This matches the previous behavior.  This forced gen protection may
be removed or softened later to improve reclaim further.

Subject: [PATCH 2885/5214] mm/mglru: avoid reclaim type fall back when
 isolation makes no progress

While isolation makes no progress in scan_folios(), we quickly fall back
to the other type in isolate_folios().  This is incorrect, as the current
type may still have sufficient folios.  Falling back can undermine the
positive_ctrl_err() result from get_type_to_scan(), which is derived from
swappiness.

So just continue scanning this type for another round.

Worth noting if the cold generations are all reclaimed, scan will no
longer make any progress either, which may undermine the swappiness again.
This is not a new issue and hence better be fixed later [1].

With a fixed number to reclaim calculated at the beginning, making each

over-aggressive reclaim of folios, as it will abort earlier when the
number of folios to be reclaimed is reached.

Subject: [PATCH 2887/5214] mm/mglru: don't abort scan immediately right after
 aging

Right now, if eviction triggers aging, the reclaimer will abort.  This is
not the optimal strategy for several reasons.

Aborting the reclaim early wastes a reclaim cycle when under pressure, and
for concurrent reclaim, if the LRU is under aging, all concurrent
reclaimers might fail.  And if the age has just finished, new cold folios
exposed by the aging are not reclaimed until the next reclaim iteration.

What's more, the current aging trigger is quite lenient, having 3 gens
with a reclaim priority lower than default will trigger aging, and blocks
reclaiming from one memcg.  This wastes reclaim retry cycles easily.  And
in the worst case, if the reclaim is making slower progress and all
following attempts fail due to being blocked by aging, it triggers
unexpected early OOM.

And if a lruvec requires aging, it doesn't mean it's hot.  Instead, the
lruvec could be idle for quite a while, and hence it might contain lots of
cold folios to be reclaimed.

While it's helpful to rotate memcg LRU after aging for global reclaim, as
global reclaim fairness is coupled with the rotation in shrink_many, memcg
fairness is instead handled by cgroup iteration in shrink_node_memcgs.
So, for memcg level pressure, this abort is not the key part for keeping
the fairness.  And in most cases, there is no need to age, and fairness
must be achieved by upper-level reclaim control.

So instead, just keep the scanning going unless one whole batch of folios
failed to be isolated or enough folios have been scanned, which is
triggered by evict_folios returning 0.  And only abort for global reclaim
after one batch, so when there are fewer memcgs, progress is still made,
and the fairness mechanism described above still works fine.

And in most cases, the one more batch attempt for global reclaim might
just be enough to satisfy what the reclaimer needs, hence improving global
reclaim performance by reducing reclaim retry cycles.

Rotation is still there after the reclaim is done, which still follows the
comment in mmzone.h.  And fairness still looking good.

Subject: [PATCH 2888/5214] mm/mglru: remove redundant swap constrained check
 upon isolation

Remove the swap-constrained early reject check upon isolation.  This check
is a micro optimization when swap IO is not allowed, so folios are
rejected early.  But it is redundant and overly broad since
shrink_folio_list() already handles all these cases with proper
granularity.

Notably, this check wrongly rejected lazyfree folios, and it doesn't cover
all rejection cases.  shrink_folio_list() uses may_enter_fs(), which
distinguishes non-SWP_FS_OPS devices from filesystem-backed swap and does
all the checks after folio is locked, so flags like swap cache are stable.

This check also covers dirty file folios, which are not a problem now
since sort_folio() already bumps dirty file folios to the next generation,
but causes trouble for unifying dirty folio writeback handling.

And there should be no performance impact from removing it.  We may have
lost a micro optimization, but unblocked lazyfree reclaim for NOIO
contexts, which is not a common case in the first place.

Subject: [PATCH 2889/5214] mm/mglru: use the common routine for
 dirty/writeback reactivation

Currently MGLRU will move the dirty writeback folios to the second oldest
gen instead of reactivate them like the classical LRU.  This might help to
reduce the LRU contention as it skipped the isolation.  But as a result we
will see these folios at the LRU tail more frequently leading to
inefficient reclaim.

Besides, the dirty / writeback check after isolation in shrink_folio_list
is more accurate and covers more cases.  So instead, just drop the special
handling for dirty writeback, use the common routine and re-activate it
like the classical LRU.

This should in theory improve the scan efficiency.  These folios will be
rotated back to LRU tail once writeback is done so there is no risk of
hotness inversion.  And now each reclaim loop will have a higher success
rate.  This also prepares for unifying the writeback and throttling
mechanism with classical LRU, we keep these folios far from tail so
detecting the tail batch will have a similar pattern with classical LRU.

The micro optimization that avoids LRU contention by skipping the
isolation is gone, which should be fine.  Compared to IO and writeback
cost, the isolation overhead is trivial.

And using the common routine also keeps the folio's referenced bits (tier
bits), which could improve metrics in the long term.  Also no more need to
clean reclaim bit as the common routine will make use of it.

Note the common routine updates a few throttling and writeback counters,
which are not used, and never have been for the MGLRU case.  We will start
making use of these in later commits.

Subject: [PATCH 2890/5214] mm/mglru: simplify and improve dirty writeback
 handling

Right now the flusher wakeup mechanism for MGLRU is less responsive and
unlikely to trigger compared to classical LRU.  The classical LRU wakes
the flusher if one batch of folios passed to shrink_folio_list is
unevictable due to under writeback.  MGLRU instead check and handle this
after the whole reclaim loop is done.

We previously even saw OOM problems due to passive flusher, which were
fixed but still not perfect [1].

We have just unified the dirty folio counting and activation routine, now
just move the dirty flush into the loop right after shrink_folio_list.
This improves the performance a lot for workloads involving heavy
writeback and prepares for throttling too.

Test with YCSB workloadb showed a major performance improvement:

Before this series:
Throughput(ops/sec): 62485.02962831822
AverageLatency(us): 500.9746963330107
pgpgin 159347462
workingset_refault_file 34522071

After this commit:
Throughput(ops/sec): 80857.08510208207
AverageLatency(us): 386.653262968934
pgpgin 112233121
workingset_refault_file 19516246

The performance is a lot better with significantly lower refault.  We also
observed similar or higher performance gain for other real-world
workloads.

We were concerned that the dirty flush could cause more wear for SSD: that
should not be the problem here, since the wakeup condition is when the
dirty folios have been pushed to the tail of LRU, which indicates that
memory pressure is so high that writeback is blocking the workload
already.

Subject: [PATCH 2891/5214] mm/mglru: remove no longer used reclaim argument
 for folio protection

Now dirty reclaim folios are handled after isolation, not before, since
dirty reactivation must take the folio off LRU first, and that helps to
unify the dirty handling logic.

So this argument is no longer needed.  Just remove it.

Subject: [PATCH 2894/5214] mm/vmscan: unify writeback reclaim statistic and
 throttling

Currently MGLRU and non-MGLRU handle the reclaim statistic and writeback
handling very differently, especially throttling.  Basically MGLRU just
ignored the throttling part.

Let's just unify this part, use a helper to deduplicate the code so both
setups will share the same behavior.

Test using following reproducer using bash:

  echo "Setup a slow device using dm delay"
  dd if=/dev/zero of=/var/tmp/backing bs=1M count=2048
  LOOP=$(losetup --show -f /var/tmp/backing)
  mkfs.ext4 -q $LOOP
  echo "0 $(blockdev --getsz $LOOP) delay $LOOP 0 0 $LOOP 0 1000" | \
      dmsetup create slow_dev
  mkdir -p /mnt/slow && mount /dev/mapper/slow_dev /mnt/slow

  echo "Start writeback pressure"
  sync && echo 3 > /proc/sys/vm/drop_caches
  mkdir /sys/fs/cgroup/test_wb
  echo 128M > /sys/fs/cgroup/test_wb/memory.max
  (echo $BASHPID > /sys/fs/cgroup/test_wb/cgroup.procs && \
      dd if=/dev/zero of=/mnt/slow/testfile bs=1M count=192)

  echo "Clean up"
  echo "0 $(blockdev --getsz $LOOP) error" | dmsetup load slow_dev
  dmsetup resume slow_dev
  umount -l /mnt/slow && sync
  dmsetup remove slow_dev

Before this commit, `dd` will get OOM killed immediately if MGLRU is
enabled.  Classic LRU is fine.

After this commit, throttling is now effective and no more spin on LRU or
premature OOM.  Stress test on other workloads also looks good.

Global throttling is not here yet, we will fix that separately later.

Subject: [PATCH 2895/5214] fs/proc/task_mmu: read proc/pid/{smaps|numa_maps}
 under per-vma lock

Patch series "use vma locks for proc/pid/{smaps|numa_maps} reads", v2.

Use per-vma locks when reading /proc/pid/smaps and /proc/pid/numa_maps
similar to /proc/pid/maps to reduce contention on central mmap_lock.  One
major difference between maps and smaps/numa_maps reading is that the
latter executes page table walk which can't be done under RCU due to a
possibility of sleeping.  Therefore we drop RCU read lock before this walk
while keeping the VMA locked.  After the walk we retake RCU read lock,
reset VMA iterator and proceed with the next VMA.

The last two patches extend /proc/pid/maps test to cover /proc/pid/smaps
reading during concurrent address space modification.


This patch (of 3):

proc/pid/{smaps|numa_maps} can be read using the combination of RCU and
VMA read locks, similar to proc/pid/maps.  RCU is required to safely
traverse the VMA tree and VMA lock stabilizes the VMA being processed and
the pagetable walk.

Subject: [PATCH 2896/5214] selftests/proc: ensure the test is performed at the
 right page boundary

When running tearing tests we need to ensure the pages we use include VMAs
that were mapped by the child process for this test.  Currently we always
use the first two pages, checking VMAs at their boundaries and this works,
however once we add tests for /proc/pid/smaps, the first two pages might
not contain the VMAs that child modifies.  Locate the page that contains
the first VMA mapped by the child and use that and the next page for the
test.

Subject: [PATCH 2897/5214] selftests/proc: add /proc/pid/smaps tearing tests

Add tearing tests for /proc/pid/smaps file.  New tests reuse the same
logic as with maps file but skipping all the data except for the VMA
addresses, which are the only part relevant for the tearing tests.  Skip
PROCMAP_QUERY parts of the tests because smaps does not implement that
ioctl.

Subject: [PATCH 2898/5214] mm: make mmap_miss accounting symmetric for
 VM_SEQ_READ

do_sync_mmap_readahead() skips both the mmap_miss increment and the
MMAP_LOTSAMISS check for VM_SEQ_READ mappings, since sequential access is
non-speculative and should always read ahead.  The two decrement sites in
do_async_mmap_readahead() and filemap_map_pages() do not mirror this skip,
so concurrent faults on a VM_SEQ_READ mapping can still drive
ra->mmap_miss down to zero through the decrement paths even though nothing
in the sync path ever increments it.  The counter itself is per-file
(file->f_ra.mmap_miss), so it can be moved by any VMA mapping the file,
not just the one currently faulting.

Skip the decrement for VM_SEQ_READ in both decrement sites so the counter
only moves for mappings that also participate in the increment side.  No
functional change for VM_SEQ_READ users, since the increment-side gate
already prevents the counter from being consulted on their behalf, but it
stops a VM_SEQ_READ mapping from biasing the counter for other mappings of
the same file.

Subject: [PATCH 2899/5214] mm: shmem: refactor thpsize_shmem_enabled_store()
 with sysfs_match_string()

Patch series "refactors thpsize_shmem_enabled_store() and
thpsize_shmem_enabled_show()", v4.


This patch (of 2):

Inspired by commit 82d9ff648c6c ("mm: huge_memory: refactor
anon_enabled_store() with set_anon_enabled_mode()"), refactor
thpsize_shmem_enabled_store() using sysfs_match_string().  This eliminates
the duplicated spin_lock/unlock(), set/clear_bit(), calls across all
branches, reducing code duplication.

Behavioral change:
Call start_stop_khugepaged() only when the mode actually changes.
If unchanged, call set_recommended_min_free_kbytes() to preserve
legacy watermark behavior. This avoids unnecessary khugepaged restarts.

Tested with selftests ./run_kselftest.sh -t mm:ksft_thp.sh,
all test cases passed.

Subject: [PATCH 2900/5214] mm: shmem: refactor thpsize_shmem_enabled_show()
 with helper arrays

Replace the hardcoded if/else chain of test_bit() calls and string
literals in thpsize_shmem_enabled_show() with a loop over
huge_shmem_orders_by_mode[] and huge_shmem_enabled_mode_strings[] arrays.

This makes thpsize_shmem_enabled_show() consistent with
thpsize_shmem_enabled_store() and eliminates duplicated mode name strings.

Subject: [PATCH 2901/5214] selftests/memfd: fix -Wmaybe-uninitialized warning
 in memfd_test

Patch series "selftests/memfd: fix compilation warnings".

This patchset fixes warnings about unused but initialized variables, and
unused dummy buffer passed to pwrite() syscall in the tests.


This patch (of 2):

  memfd_test.c: In function 'mfd_fail_grow_write.part.0':
  memfd_test.c:685:13: warning: '<unknown>' may be used uninitialized
  [-Wmaybe-uninitialized]
    685 |         l = pwrite(fd, buf, mfd_def_size * 8, 0);
        |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

pwrite() is declared with attribute 'access (read_only, 2, 3)', so GCC
knows it reads from the buffer.  malloc() returns uninitialized memory,
hence the warning.  Use calloc() to zero-initialize the buffer.  The
actual contents don't matter here since the test verifies that pwrite()
fails on a sealed memfd.

Subject: [PATCH 2903/5214] memcg: store node_id instead of pglist_data pointer

Patch series "memcg: shrink obj_stock_pcp and cache multiple objcgs", v3.

Commit 01b9da291c49 ("mm: memcontrol: convert objcg to be per-memcg
per-node type") split a memcg's single obj_cgroup into one per NUMA node
so that reparenting LRU folios can take per-node lru locks.  As a side
effect, the per-CPU obj_stock_pcp -- which caches a single cached_objcg
pointer -- thrashes on workloads where threads of the same memcg run on
different NUMA nodes.  The kernel test robot reported a 67.7% regression
on stress-ng.switch.ops_per_sec from this pattern.

Commit d0211878ce06 ("memcg: cache obj_stock by memcg, not by objcg
pointer") landed as a temporary fix by treating sibling per-node objcgs as
equivalent for the cache lookup, intended to be reverted once per-node
kmem accounting is introduced.  This series takes a more general approach:
cache multiple objcgs per CPU using the multi-slot pattern memcg_stock_pcp
already uses, so the per-node objcg variants of one memcg can all coexist
in the stock without ever forcing a drain.  The temporary fix can then be
reverted.

To avoid increasing the per-CPU cache footprint, the first three patches
shrink the existing single-slot obj_stock_pcp fields.  The final patch
converts cached_objcg and nr_bytes into NR_OBJ_STOCK=5 slot arrays and
reorders the struct so the entire consume/refill/account hot path fits
within a single 64-byte cache line on non-debug 64-bit builds (verified
with pahole).


This patch (of 4):

The struct obj_stock_pcp stores a pointer to pglist_data for the slab
stats cached on the cpu.  On 64-bit machines, this costs 8 bytes.  The
pointer is not strictly required: NODE_DATA() can recover it from the node
id.  Replace cached_pgdat with int16_t node_id and use NUMA_NO_NODE as the
"no stats cached" sentinel.

At the moment all the archs limit MAX_NUMNODES to 1024 so int16_t is
plenty; a BUILD_BUG_ON() makes sure we notice if that ever changes.

Subject: [PATCH 2904/5214] memcg: uint16_t for nr_bytes in obj_stock_pcp

Currently struct obj_stock_pcp stores nr_bytes in an 'unsigned int' which
is 4 bytes on 64-bit machines.  Switch the field to uint16_t to shrink the
per-CPU cache.

The kernel supports PAGE_SIZE_4KB, _8KB, _16KB, _32KB, _64KB and _256KB
(see HAVE_PAGE_SIZE_* in arch/Kconfig).  After the PAGE_SIZE-aligned flush
in __refill_obj_stock(), the sub-page remainder fits in uint16_t up
through 64KiB pages where PAGE_SIZE - 1 == U16_MAX, but on 256KiB pages
PAGE_SIZE - 1 == 0x3FFFF exceeds U16_MAX.  The accumulator also needs to
stay within uint16_t between page-aligned flushes on 64KiB pages where
PAGE_SIZE itself is U16_MAX + 1.

Accumulate the new total in an 'unsigned int' local, then on PAGE_SHIFT <=
16 flush whenever the accumulator would hit U16_MAX; together with the
existing allow_uncharge flush at PAGE_SIZE this keeps the uint16_t safe.

On configs with PAGE_SHIFT > 16 (PAGE_SIZE_256KB on hexagon and powerpc
44x, both 32-bit), uint16_t cannot represent the sub-page remainder.
Define obj_stock_bytes_t as 'unsigned int' on those archs so nr_bytes can
hold the full remainder and the normal page-boundary flush in
__refill_obj_stock() and the page extraction in drain_obj_stock() both
work correctly.

The single-cache-line layout target only applies to PAGE_SHIFT <= 16;
those archs are 32-bit embedded and not the optimization target.

Subject: [PATCH 2905/5214] memcg: int16_t for cached slab stats

Currently struct obj_stock_pcp stores cached slab stats in 'int' which is
4 bytes per counter on 64-bit machines.  Switch them to int16_t to shrink
the cached metadata.

The existing PAGE_SIZE flush in __account_obj_stock() bounds *bytes at
PAGE_SIZE on 4KiB and 16KiB page archs, well within int16_t.  On 64KiB
pages PAGE_SIZE is well above S16_MAX so that flush never fires, and a
sufficiently long run of accumulations would overflow the cache.  Add an
explicit S16_MAX guard before each add: when the next add would push
abs(*bytes) past S16_MAX, fold the cached value into @nr and flush
directly via mod_objcg_mlstate() before the accumulation.

Subject: [PATCH 2906/5214] memcg: multi objcg charge support

Commit 01b9da291c49 ("mm: memcontrol: convert objcg to be per-memcg
per-node type") split a memcg's single obj_cgroup into one per NUMA node
so that reparenting LRU folios can take per-node lru locks.  As a side
effect, the per-CPU obj_stock_pcp -- which caches exactly one cached_objcg
-- thrashes on workloads where threads of the same memcg run on different
NUMA nodes.  The kernel test robot reported a 67.7% regression on
stress-ng.switch.ops_per_sec from this pattern.

Mirror the multi-slot pattern already used by memcg_stock_pcp: turn
nr_bytes and cached_objcg into NR_OBJ_STOCK-element arrays, scan all slots
on consume/refill/account, prefer empty slots when inserting, and evict a
slot round-robin only when full.  With multiple slots a CPU can hold the
per-node objcg variants of one memcg plus a few siblings without ever
forcing a drain.

A single int8_t index records which slot the cached slab stats belong to;
the stats are flushed on slot or pgdat change.  With NR_OBJ_STOCK = 5 the
layout (verified with pahole) is:

  offset 0  : lock(1) + index(1) + node_id(2) + slab stats(4) = 8B
  offset 8  : nr_bytes[5]                                     = 10B
  offset 18 : padding                                         = 6B
  offset 24 : cached[5]                                       = 40B
  offset 64 : (line 2) work_struct + flags (cold)

so consume_obj_stock, refill_obj_stock and the slab account path each
touch exactly one 64-byte cache line on non-debug 64-bit builds.

Subject: [PATCH 2907/5214] zram: do not leak blk idx at the end of writeback

zram_writeback_slots() loop can terminate with valid reserved backing
device blk_idx.  The problem is that cleanup code doesn't release that
reserved blk_idx before zram_writeback_slots() returns, which leads to
blk_idx leak (it becomes permanently busy and can not be used for actual
writeback.) This does not lead to any system instabilities, it only means
that we can writeback less pages.  The scenario is hard to hit in practice
as it requires writeabck to race with modification (slot-free or
overwrite) of the final post-processing slot.

Release reserved but unused blk_idx before returning from
zram_writeback_slots().

Subject: [PATCH 2908/5214] zram: clear trailing bytes of compressed writeback
 pages

Patch series "zram: writeback fixes", v2.

Brian (privately) reported a "leak" of writeback bitmap in certain cases,
so that backing device can store less pages; and a theoretical data leak
in the trailing bytes of compressed writeback pages.  Both issues are low
risk.


This patch (of 2):

When compressed writeback is available writtenback pages contain "garbage"
in PAGE_SIZE - obj_size trailing bytes.  That "garbage" is, basically,
whatever data that page held before we got it for writeback.  To get
advantage of it an attacker needs to be able to read from active backing
swap device, which is already catastrophic.  Still, just in case, zero out
those trailing bytes before writeback to a backing device so that we only
store swap-ed out data there.

 security checks and suid exec

The target task can execute a setuid binary between ptrace_may_access()
and get_task_mm().  Protect this critical section with exec_update_lock.

I don't think cpuset_mems_allowed(task) should be called under
exec_update_lock, but this patch just tries to add the minimal fix.

Perhaps we can later add a common helper which can be used by
find_mm_struct() and kernel_migrate_pages().

that it has no effect when overcommit_memory is set to 0 or 1.

Subject: [PATCH 2914/5214] ocfs2: rebase copied fsdlm LVB pointers in
 locking_state

The locking_state debugfs iterator snapshots struct ocfs2_lock_res by
value under ocfs2_dlm_tracking_lock and later formats that copy in
ocfs2_dlm_seq_show().  That is fine for the inline fields, but the
userspace fsdlm stack stores the LVB through lksb_fsdlm.sb_lvbptr.  Once
the iterator drops the tracking lock, a copied non-NULL sb_lvbptr still
points into the original lockres owner, so teardown can free that
container before the debugfs dump walks the raw LVB bytes.

Rebase the copied sb_lvbptr to the copied l_lksb before dumping the raw
LVB.  The seq snapshot already carries the inline LVB storage reserved in
struct ocfs2_dlm_lksb, so the debugfs reader can dump the copied bytes
without borrowing the original lockres lifetime.

The buggy scenario involves two paths, with each column showing the order
within that path:

locking_state reader:                  lockres teardown:
1. ocfs2_dlm_seq_start()/next()        1. file release or another owner
   copies struct ocfs2_lock_res           teardown reaches
2. ocfs2_dlm_seq_show() formats           ocfs2_lock_res_free()
   the copied row                      2. the lockres is removed from the
3. ocfs2_dlm_lvb() follows the            tracking list
   copied sb_lvbptr                   3. the owner frees the original
                                          lockres container

Subject: [PATCH 2915/5214] kcov: use WRITE_ONCE() for selftest mode stores

The KCOV selftest enables coverage by setting current->kcov_mode to
KCOV_MODE_TRACE_PC without installing a coverage area.  If an interrupt
records coverage in that window, the access should fault and expose the
bug.

When building for QEMU raspi0 (Raspberry Pi Zero, ARMv6, CONFIG_CPU_V6K=y,
CONFIG_CURRENT_POINTER_IN_TPIDRURO=y) with GCC 13.3.0, the store that
enables the mode is removed.  The generated kcov_init() code only stores
zero after the wait loop:

  mrc	15, 0, r3, cr13, cr0, {3}
  str	r4, [r3, #2028]

where r4 is zero.  There is no store of KCOV_MODE_TRACE_PC before the
loop, so the selftest reports success without exercising coverage.

Use WRITE_ONCE() for the temporary mode stores.  With the same compiler
and config, kcov_init() contains the intended mode store:

  mov	r3, #2
  mrc	15, 0, r2, cr13, cr0, {3}
  str	r3, [r2, #2028]

Now that the KCOV selftest is actually executed, it may expose KCOV
instrumentation issues depending on the kernel config.  That is expected
for a selftest that was intended to catch coverage from interrupt paths.

Subject: [PATCH 2916/5214] err.h: use __always_inline on all error pointer
 helpers

While testing randconfig builds on s390, I came across a link failure with
CONFIG_DMA_SHARED_BUFFER disabled:

ERROR: modpost: "dma_buf_put" [drivers/iommu/iommufd/iommufd.ko] undefined!

The problem here is that IS_ERR() is not inlined and dead code elimination
fails as a consequence.

The err.h helpers all turn into a trivial assignment of a bit mask and
should never result in a function call, so force them to always be inline.
This should generally result in better object code aside from avoiding
the link failure above.

Subject: [PATCH 2918/5214] ocfs2: reject oversized group bitmap descriptors

ocfs2_validate_gd_parent() only bounds bg_bits against the parent
allocator's chain geometry.  A malicious descriptor can still claim a
bg_size/bg_bits pair that exceeds the bitmap bytes that physically fit in
the group descriptor block, so later bitmap scans and bit updates can run
past bg_bitmap.

Add a physical-cap check based on ocfs2_group_bitmap_size() for the parent
allocator type and reject descriptors whose bg_size or bg_bits exceed that
capacity.  Keep the existing chain geometry check so both the on-disk
bitmap layout and the allocator metadata must agree before the descriptor
is used.

Subject: [PATCH 2921/5214] ocfs2: fix buffer head management in
 ocfs2_read_blocks()

In ocfs2_read_blocks(), caller should't assume that buffer head returned
by 'sb_getblk()' is exclusively owned and so 'put_bh()' always drops
b_count from 1 to 0.  If it is not so, buffer head remains on hold and
likely to be returned by the next call to 'sb_getblk()' unchanged - that
is, with BH_Uptodate bit set even if it has failed validation previously,
thus allowing to insert that buffer head into OCFS2 metadata cache and
submit it to upper layers.  To avoid such a scenario, BH_Uptodate should
be cleared immediately after 'validate()' callback has detected some data
inconsistency.

Subject: [PATCH 2922/5214] ocfs2: add journal NULL check in
 ocfs2_checkpoint_inode()

During unmount, ocfs2_journal_shutdown() frees the journal and sets
osb->journal to NULL. Later, when VFS evicts remaining cached inodes,
ocfs2_evict_inode() -> ocfs2_clear_inode() -> ocfs2_checkpoint_inode()
-> ocfs2_ci_fully_checkpointed() dereferences osb->journal, causing a
NULL pointer dereference.

Fix this by adding a NULL check for osb->journal in
ocfs2_checkpoint_inode(). If the journal is NULL, it has already been
fully flushed and destroyed during shutdown, so there is nothing to
checkpoint.

Subject: [PATCH 2923/5214] ocfs2: validate fast symlink target during inode
 read

ocfs2_validate_inode_block() already rejects several inconsistent
self-contained dinodes before they are exposed to the rest of the
filesystem.  Fast symlinks need the same treatment.

A zero-cluster symlink is treated as a fast symlink and later read through
page_get_link() and ocfs2_fast_symlink_read_folio().  That path uses
strnlen() on the inline payload and then copies len + 1 bytes into the
folio.  If a corrupt dinode stores an i_size that does not fit the inline
area or omits the terminating NUL at i_size, that copy reads past the end
of the inode block buffer.

Reject zero-cluster symlink dinodes whose i_size exceeds the inline
fast-symlink capacity or whose inline payload is not NUL-terminated
exactly at i_size when the inode block is validated.  This keeps malformed
fast symlinks from reaching the read path.

Subject: [PATCH 2924/5214] ocfs2: reject FITRIM ranges shorter than a cluster

ocfs2_trim_mainbm() trims the global bitmap in cluster units, but its
too-short range validation only checks sb->s_blocksize.

On filesystems with a cluster size larger than the block size, a FITRIM
range that is at least one block but shorter than one cluster is accepted
and shifted down to len == 0.  The later start + len - 1 and len -= ...
arithmetic then underflows and can drive trimming past the requested
range.

Reject ranges shorter than s_clustersize instead.  That preserves the
existing -EINVAL behavior for requests that cannot discard even one
allocation unit and keeps zero-cluster trims out of the group walk.

Subject: [PATCH 2925/5214] ocfs2/dlm: require a ref for locking_state debugfs
 open

debug_lockres_open() copies inode->i_private into struct debug_lockres and
debug_lockres_release() later drops that pointer with dlm_put().  That
only works if open successfully pins the struct dlm_ctxt.

Today open calls dlm_grab(dlm) but ignores its return value.  Once the
last domain unregister has removed the context from dlm_domains,
dlm_grab() returns NULL, yet open still stores the raw pointer and returns
success.  The later release path is outside the debugfs removal barrier,
so it can call dlm_put() after dlm_free_ctxt_mem() has freed the context.
KASAN reports this as a slab-use-after-free in dlm_put() called from
debug_lockres_release().

Fail the open when dlm_grab() cannot acquire the reference and unwind the
seq_file private state before returning.  That keeps locking_state from
handing out a file descriptor whose release path does not own the
dlm_ctxt.

The buggy scenario involves two paths, with each column showing the order
within that path:

locking_state debugfs open:          last domain unregister:
1. debug_lockres_open() reads        1. dlm_unregister_domain() calls
   inode->i_private.                    dlm_complete_dlm_shutdown().
2. debug_lockres_open() calls        2. shutdown removes the dlm_ctxt from
   dlm_grab(dlm) and gets NULL.         dlm_domains.
3. open still stores the raw dlm     3. final teardown reaches
   pointer in dl->dl_ctxt and           dlm_free_ctxt_mem() and frees it.
   returns success.
4. debug_lockres_release() later
   calls dlm_put(dl->dl_ctxt).

Subject: [PATCH 2927/5214] ocfs2: fix out-of-bounds write in
 ocfs2_remove_refcount_extent

[BUG]
Unlinking a refcounted file whose refcount tree has leaf blocks
triggers a fortify panic due to an out-of-bounds write.

[CAUSE]
When the last leaf block is removed from a refcount tree,
ocfs2_remove_refcount_extent() converts the root back to leaf mode
with a bulk memset on &rb->rf_records. rf_records sits in an anonymous
union with rf_list. rf_list.l_tree_depth aliases rf_records.rl_count,
and is 0 for a single-level tree. With rl_count equal to 0, the memset
writes past the 16-byte declared size of rf_records, which the fortify
checker catches.

[FIX]
Replace the bulk memset on &rb->rf_records with a correctly-bounded
memset on rl_recs[] alone, after setting rl_count to the correct value.

Subject: [PATCH 2928/5214] perf tools: Guard remaining test_bit calls from OOB
 sample CPU

auxtrace.c:filter_cpu() and builtin-script.c:filter_cpu() call
test_bit(cpu, cpu_bitmap) where cpu_bitmap is declared with
MAX_NR_CPUS bits.  When the CPU value from a perf.data event is
corrupt or absent (e.g. negative or >= MAX_NR_CPUS), test_bit reads
out of bounds.

Add bounds checks before test_bit(): >= 0 for the int16_t cpu.cpu in
auxtrace (which also covers the -1 sentinel), and < MAX_NR_CPUS for
both sites.  Matches the pattern applied in the previous series for
builtin-annotate.c, builtin-diff.c, builtin-report.c, and
builtin-sched.c.

cpu__get_node() accesses cpunode_map[cpu.cpu] without checking against
max_cpu_num, the allocation size of cpunode_map.  Callers such as
builtin-kmem.c:evsel__process_alloc_event() pass sample->cpu from
perf.data events, which may exceed the host's CPU count when analyzing
cross-machine recordings.

Add a bounds check against max_cpu_num before indexing, returning -1

Subject: [PATCH 2930/5214] perf sched: Fix thread reference leaks in
 timehist_get_thread()

timehist_get_thread() acquires a thread reference via
machine__findnew_thread() and an idle thread reference via
get_idle_thread() (which calls thread__get()).  Two error paths in
the idle_hist block return NULL without releasing these references:

 - When get_idle_thread() fails, the thread reference leaks.
 - When thread__priv(idle) returns NULL, both idle and thread leak.

Additionally, the idle thread reference acquired on the success path
is never released, leaking a reference on every sample when
--idle-hist is active.

Add thread__put() calls on both error paths and release the idle
reference after use on the success path.

Subject: [PATCH 2932/5214] cxl/pci: Convert PCIBIOS errors to errno on DVSEC
 config accesses

PCI config space accessors return positive PCIBIOS_* status codes on
failure that are positive integers. Several DVSEC accesses in the CXL
core propagated these raw values to callers that test for failure against
less than 0. Thus silently misinterpret the return value as success.

Convert the positive error values to negative errno values so the checks
are correct on error paths.

While the chances of a config access failure are low, fix for correctness
and to avoid confusion in the future when more DVSEC accesses are added.

Subject: [PATCH 2933/5214] media: v4l2-fwnode: Fix subdev owner overwritten in
 v4l2_async_register_subdev_sensor()

The v4l2 helper v4l2_async_register_subdev_sensor() calls
v4l2_async_register_subdev(), which is a macro that expands to
__v4l2_async_register_subdev(sd,THIS_MODULE). Since the macro is expanded
inside v4l2-fwnode.c, THIS_MODULE resolves to the v4l2-fwnode module
rather than the sensor driver module that originally set sd->owner. When
v4l2-fwnode is built-in, THIS_MODULE evaluates to NULL, which then
overwrites the sensor driver's owner with NULL.

This causes the problem that the sensor module's reference count is never
incremented during async registration, so the module can be removed while
the subdevice is still in use by a notifier (e.g., a CSI-2 receiver
bridge driver).

Fix this by renaming v4l2_async_register_subdev_sensor() to
__v4l2_async_register_subdev_sensor() with an added explicit module
argument and introducing a wrapper macro:
    #define v4l2_async_register_subdev_sensor(sd) \
        __v4l2_async_register_subdev_sensor(sd, THIS_MODULE)

This ensures the sensor driver module is properly referenced even when
the sensor driver does not init the owner field before calling
v4l2_async_register_subdev_sensor() and prevents premature module removal.

Subject: [PATCH 2934/5214] pinctrl: renesas: rzg2l: Use raw_spinlock_irqsave()
 on power source update

The rest of the driver uses raw_spin_lock_irqsave() and
raw_spin_unlock_irqrestore() for locking.  To avoid concurrency issues
or deadlocks, use raw_spinlock_irqsave() via the scoped_guard() helper
for power source updates as well.

Subject: [PATCH 2935/5214] RISC-V: KVM: Enhance the logging check for mmu
 mapping

When enabling dirty ring, the dirty bitmap is disable, and the logging
check is always false as the RISC-V architecture does not select
"NEED_KVM_DIRTY_RING_WITH_BITMAP". Although the dirty log is recorded
since the write path already trying to add the dirty log, the logic for
logging check is broken and some side effect will occurs.

Enhance the logging check for mmu mapping so it can check both the dirty
ring and the dirty bitmap.

Subject: [PATCH 2936/5214] ntfs: free volume-wide resources on fill_super
 failure

ntfs_fill_super()'s err_out_now path frees only the volume struct via
kfree(vol), leaving several vol-owned allocations behind on every mount
failure:

  - vol->nls_map, loaded by ntfs_init_fs_context() via
    load_nls_default() (or replaced by an explicit nls= option in
    ntfs_parse_param()), is never unload_nls()'d.

  - vol->volume_label, allocated by load_system_files() through
    ntfs_ucstonls() once the $Volume name attribute has been parsed, is
    not released by load_system_files()'s own error labels nor by the
    fill_super() inline cleanup that only runs on d_make_root()
    failure.  Any later failure inside load_system_files() leaks it.

  - vol->lcn_empty_bits_per_page was kvfree()'d in
    unl_upcase_iput_tmp_ino_err_out_now without clearing the pointer,
    so it could not be folded into a single common cleanup.

Because the failure paths never call ntfs_volume_free() and never reach
the d_make_root() inline cleanup block (it sits above the label and is
jumped over by the load_system_files() / kvmalloc failure gotos), these
resources accumulate per failed mount attempt with no chance of
recovery short of unloading the module.  This is a silent leak: the
inodes loaded prior to failure remain hashed but generic_shutdown_super()
skips evict_inodes() when sb->s_root is unset, so no CHECK_DATA_CORRUPTION
warning is emitted either.

Move the per-volume frees down to err_out_now and drop the
lcn_empty_bits_per_page kvfree() from the upper label so the cleanup is
performed exactly once on every failure path.  Using unconditional
kvfree() / kfree() / unload_nls() is safe because they all accept NULL
and the upper labels that previously freed nls_map (the d_make_root()
inline cleanup) already clear the pointer.

Subject: [PATCH 2937/5214] ntfs: only alias volume $UpCase to default on exact
 match

load_and_init_upcase() currently aliases vol->upcase to the global
default upcase whenever the shared prefix matches, and then truncates
vol->upcase_len to that shorter prefix.  The result is correct only by
accident: upcase[] accesses in name collation are gated by upcase_len,
so the prefix-equality alias produces the same fold output as keeping
the volume's own shorter table.

Still, prefix equality is not equality: the volume table is logically
distinct from the default and should not be replaced by it unless they
are byte-for-byte identical.  Use memcmp() to compare the complete table
in one expression and drop the now-redundant upcase_len rewrite.

No user-visible change is expected for compliant volumes whose $UpCase
has exactly default_upcase_len entries; shorter volume tables are no
longer aliased to the default.

Subject: [PATCH 2938/5214] ntfs: skip extent mft records in writeback to
 prevent deadlock

This patch fixes the ABBA deadlock between extent_lock and extent
mrec_lock triggered by xfstests generic/113, that occurs since the commit
6994acf33bae ("ntfs: use base mft_no when looking up base inode for
		extent record").

Path A (inode writeback):
  VFS writeback
    -> ntfs_write_inode()
      -> __ntfs_write_inode()
        -> mutex_lock(&ni->extent_lock)
        -> mutex_lock(&tni->mrec_lock)

Path B (MFT folio writeback):
  VFS writeback of $MFT dirty folios
    -> ntfs_mft_writepages()
      -> ntfs_write_mft_block()
        -> ntfs_may_write_mft_record()
          -> holds one extent mrec_lock from a previous iteration
          -> tries to acquire another base inode extent_lock

By removing all extent_lock and extent mrec_lock acquisition from the MFT
folio writeback path, the ABBA lock ordering is eliminated:

Path A: __ntfs_write_inode(): extent_lock -> mrec_lock
Path B (removed): ntfs_write_mft_block(): mrec_lock -> extent_lock

Path B is always redundant for extent records because:

1. mark_mft_record_dirty(ext_ni) does NOT dirty the MFT folio.
   It only sets NInoDirty(ext_ni) and marks the base VFS inode dirty
   via __mark_inode_dirty(I_DIRTY_DATASYNC), which triggers Path A.
   Therefore, normal extent modifications never create a situation where
   the MFT folio is dirty and Path B is not scheduled.

2. The MFT folio only gets dirtied via ntfs_mft_mark_dirty() inside
   ntfs_mft_record_alloc(). But all identified callers in attrib.c
   (ntfs_attr_add, ntfs_attr_record_move_away,
   ntfs_attr_make_non_resident, ntfs_attr_record_resize) follow through
   with mark_mft_record_dirty(), which triggers Path A to write the
   complete record.

3. ntfs_evict_big_inode() calls ntfs_commit_inode() before freeing extent
   inodes, ensuring all dirty extents are flushed via Path A before the
   base inode leaves the icache.

Subject: [PATCH 2939/5214] ntfs: avoid heap allocation for free-cluster
 readahead state

get_nr_free_clusters() allocates a temporary file_ra_state before it
publishes the precomputed free cluster count, sets NVolFreeClusterKnown(),
and wakes vol->free_waitq. If that allocation fails, the worker returns
without setting the flag or waking waiters, so callers waiting for the free
count can block indefinitely.

The readahead state is only used synchronously while scanning the bitmap.
Keep it on the stack and pass it by address to the readahead helper. This
eliminates the early allocation failure path instead of adding a special
case that publishes a conservative count and wakes the waitqueue.
Zero-initialize the on-stack state because file_ra_state_init() only sets
ra_pages and prev_pos.

Apply the same treatment to __get_nr_free_mft_records(), which scans the
MFT bitmap with the same short-lived readahead state.

Subject: [PATCH 2940/5214] ntfs: validate index block header more strictly

Modify ntfs_index_block_inconsisent() to perform stricter validation of
INDEX_HEADER geometry in INDX blocks, and update
ntfs_lookup_inode_by_name() to use that function to validate INDX
blocks.

Subject: [PATCH 2941/5214] ntfs: centalize $INDEX_ROOT header validation

Add a dedicated helper to perform stricter validation of $INDEX_ROOT and
use it for both directory inodes and named index inodes. This keeps the
root size and header geometry checks consistent across both read paths.

Subject: [PATCH 2942/5214] ntfs: validate index entries on reading

Validate index entries immediately after reading an index root or index
block from disk. This eliminates repeated checks in lookup and readdir,
and reduce the risk of missing checks in those paths.

Subject: [PATCH 2945/5214] ntfs: remove unsupported quota handling

The ntfs driver does not implement quota accounting.  It creates
new inodes with the NTFS 1.2 $STANDARD_INFORMATION layout and does
not maintain the NTFS 3.x owner_id/quota_charged fields or the
$Quota usage records that Windows would need for meaningful quota
accounting.

The only runtime quota path left in the driver is the remount-rw
code that tries to mark $Quota/$Q out of date, plus the mount-time
code that loads $Quota and its $Q index solely to support that
marker.

Since the driver does not maintain the per-file quota metadata,
setting QUOTA_FLAG_OUT_OF_DATE does not make the quota state
meaningful, and failures in this unsupported path can unnecessarily
block remount-rw or force a mount read-only.

Remove the quota marker, the $Quota/$Q loading state, and the
unused quota volume flag.  Keep the on-disk quota layout definitions
in layout.h so the documented NTFS structures remain available.

Subject: [PATCH 2948/5214] ntfs: free link name from ntfs_name_cache

ntfs_link() converts the new link name with ntfs_nlstoucs() using
NTFS_MAX_NAME_LEN. In this case ntfs_nlstoucs() allocates the result
from ntfs_name_cache, and its contract requires callers to release the
buffer with kmem_cache_free(ntfs_name_cache, ...).

All other ntfs_nlstoucs() callers in namei.c do that, but ntfs_link()
uses kfree(), which mismatches the allocator for successfully converted
names.

The conversion failure path reaches the common out label with uname ==
NULL. That was harmless for kfree(), but kmem_cache_free() does not
provide the same NULL contract. Return directly on conversion failure
and free successful conversions with ntfs_name_cache.

When ntfs_resident_attr_resize() cannot grow a resident attribute in
place, it retries after converting other resident attributes to
non-resident to free space in the MFT recrord.

Do not select zero-length resident $DATA attributes for this conversion.
fsck treats 0-byte non-resident $DATA attribute as corruptions.

Subject: [PATCH 2951/5214] ntfs: fix off-by-one in mapping pairs decoding
 bounds checks

In ntfs_mapping_pairs_decompress(), attr_end points one byte past the
end of the attribute record:

    attr_end = (u8 *)attr + le32_to_cpu(attr->length);

The two bounds checks validating that mapping pair data bytes fit within
the attribute use strict greater-than (>), which allows a one-byte
out-of-bounds read when the data extends exactly to attr_end:

  b = *buf & 0xf;
  if (b) {
      if (unlikely(buf + b > attr_end))   // off-by-one
          goto io_error;
      for (deltaxcn = (s8)buf[b--]; b; b--)
          deltaxcn = (deltaxcn << 8) + buf[b];
  }

When buf + b == attr_end, the check evaluates to false and buf[b] reads
one byte past the valid attribute boundary. The same pattern appears in
the LCN delta bytes check.

Fix both checks to use >= so that buf[b] at exactly attr_end is
correctly rejected as out of bounds.

Subject: [PATCH 2953/5214] ntfs: Add WQ_PERCPU to alloc_workqueue users
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:

  commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
  commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")

The refactoring is going to alter the default behavior of
alloc_workqueue() to be unbound by default.

With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU. For more details see the Link tag below.

In order to keep alloc_workqueue() behavior identical, explicitly request
WQ_PERCPU.

Subject: [PATCH 2954/5214] ntfs: detect mapping-pairs LCN accumulator overflow

The NTFS mapping-pairs parser accumulates relative LCN deltas in a
signed integer.  A corrupted attribute can drive that addition past
the representable range.

One corrupt runlist shape sets the accumulated LCN to S64_MAX and
then adds a delta of 1 in the next mapping-pairs entry.

Signed overflow is undefined and can turn an invalid runlist into a
different set of physical clusters.

Check the LCN addition for overflow before storing the next run.

Subject: [PATCH 2955/5214] ntfs: validate attribute values on lookup

ntfs_attr_find() and ntfs_external_attr_find() check that generic
resident attribute values fit in their attribute records and that
fixed-size resident values are large enough. For variable-length resident
formats, however, the fixed part is not enough: embedded length fields
can still point callers past the resident value.

A crafted image can set a small resident $FILE_NAME value_length while
leaving file_name_length large. Callers then trust file_name_length and
read past the resident value when converting or comparing the name. This
was reproduced with a crafted image under KASAN as a slab-out-of-bounds
read from the kmalloc-1k MFT record copy. The stack included
ntfs_lookup(), ntfs_iget(), ntfs_read_locked_inode(), ntfs_attr_name_get(),
ntfs_ucstonls(), and utf16s_to_utf8s().

Add a shared attribute value validator and use it before a lookup path
can return an attribute, including the AT_UNUSED enumeration case where
callers inspect returned attributes directly. The helper validates
resident value bounds, minimum resident value sizes, variable-length
$FILE_NAME fields, and non-resident mapping-pairs metadata that was
previously checked separately in both lookup paths.

This also preserves the intended resident @val matching semantics in the
external attribute lookup path. The old duplicated validation block
overwrote the actual resident value length with the type-specific minimum
length before comparing @val, so variable-length resident values could
fail to match even when the bytes were identical. Keep the comparison on
the actual value length, and make ntfs_attrlist_entry_add() compare
resident attributes with lowest_vcn zero instead of reading the
non-resident union member after a successful resident match.

Reject non-resident $FILE_NAME records too: the format requires
$FILE_NAME to be resident and callers treat returned records as resident.

Subject: [PATCH 2956/5214] ntfs: do not replace volume name after lookup
 errors

ntfs_write_volume_label() removes an existing $VOLUME_NAME attribute and
then adds the replacement. The old code only distinguished lookup success
from all other results, so any lookup error was treated like an absent
label and the add path still ran.

That is unsafe once lookup-time validation rejects corrupt $VOLUME_NAME
records with -EIO: the corrupt record would remain in place and a second
$VOLUME_NAME record could be appended next to it.

Only add the replacement after the old label was removed successfully or
after lookup returned -ENOENT. Propagate all other lookup errors, and
also stop if removing the old attribute fails.

Subject: [PATCH 2957/5214] ntfs: reinit search context before volume
 information lookup

On mount the volume inode is searched for $VOLUME_NAME and then, reusing
the same search context, for $VOLUME_INFORMATION. The $VOLUME_NAME lookup
is optional and its result is otherwise ignored.

Once lookup-time validation can reject a corrupt $VOLUME_NAME with -EIO,
the search context is left in an undefined state: ntfs_attr_find()
documents that on an actual error @ctx->attr is undefined. Continuing the
$VOLUME_INFORMATION search from that context is not contractually valid.

Reinitialize the search context before the $VOLUME_INFORMATION lookup so
it always starts from a well-defined state regardless of the
$VOLUME_NAME lookup outcome.

Subject: [PATCH 2958/5214] ntfs: validate resident volume name values on
 lookup

The shared lookup-time attribute validator now has a safe caller path for
$VOLUME_NAME corruption: ntfs_write_volume_label() no longer treats
lookup errors as an absent label, and the mount path reinitializes its
search context before continuing to $VOLUME_INFORMATION.

Add $VOLUME_NAME-specific resident value validation. A volume name is
stored as a UTF-16LE string, so reject odd byte lengths, and reject
values longer than the NTFS volume label limit. Empty labels remain
valid.

Also reject non-resident $VOLUME_NAME records. $VOLUME_NAME is required
to be resident, like $FILE_NAME; a crafted non-resident record would
otherwise pass lookup and ntfs_write_volume_label() would remove it as if
it were a normal resident attribute.

Subject: [PATCH 2959/5214] KVM: RISC-V: SBI FWFT: Mark vCPU CSRs dirty after
 setting feature value

Mark the vCPU CSRs as dirty after successfully setting an FWFT feature
value. FWFT features may modify CSRs (e.g., pointer masking modifies
henvcfg.PMM), and failing to mark them dirty can lead to the guest
observing stale CSR state after vCPU scheduling or migration.

Subject: [PATCH 2960/5214] KVM: RISC-V: SBI FWFT: Add optional init() callback
 for hardware probing

Add an optional init() callback to separate one-time hardware probing
from runtime availability checks. For pointer masking, this allows
probing supported PMM lengths during initialization while checking ISA
extension availability at runtime.

Fix try_to_set_pmm() to restore the previous HENVCFG.PMM value after
probing, preventing side effects from hardware detection. Add preemption
protection to ensure CSR probe sequences complete atomically on the same
CPU.

Subject: [PATCH 2961/5214] KVM: RISC-V: SBI FWFT: Fix stale feature exposure
 after runtime extension changes

Fix a bug where FWFT features could be incorrectly exposed to guests
after userspace disables their dependent ISA extensions at runtime.

The 'supported' field in kvm_sbi_fwft_config was set once during vCPU
initialization based on the initial hardware/extension availability.
However, when userspace subsequently disables ISA extensions via the KVM
ONE_REG interface, the 'supported' field was not updated. This caused
the following issues:
1. FWFT features would remain visible and accessible to guests even
   after their prerequisite ISA extensions were disabled
2. Guests could configure FWFT features that depend on disabled
   extensions, leading to undefined behavior
3. The static 'supported' flag and the dynamic supported() callback
   could disagree about feature availability

The fix introduces a two-layer checking mechanism:
1. Add an optional init() callback to the kvm_sbi_fwft_feature structure
   for features that require hardware probing during initialization. This
   separates the one-time hardware detection logic from the runtime
   availability check.
2. Add runtime checks in all FWFT-related functions that call
   feature->supported(vcpu) if the callback exists. This ensures feature
   availability is re-evaluated based on the current ISA extension state.

This approach maintains the cached 'supported' field for initialization-
time decisions while ensuring runtime availability is always determined
by the current vCPU configuration, not initialization-time snapshots.

Subject: [PATCH 2962/5214] KVM: riscv: selftests: Refactor ISA and SBI
 extension sublist macros

Refactor the get-reg-list test to use unified sublist macros for ISA
and SBI extensions, eliminating code duplication and improving
maintainability.

Previously, each extension had its own hand-coded sublist definition
(e.g., SUBLIST_ZICBOM, SUBLIST_AIA, etc.) and the config structures
repeated the same pattern. This made the code verbose and error-prone.

Subject: [PATCH 2963/5214] KVM: riscv: selftests: Split SBI FWFT into separate
 feature-specific sublists

Divide the monolithic SBI FWFT (Firmware Features) register list into
separate sublists, each testing a specific FWFT feature independently
with proper dependency checking.

Previously, all FWFT features were tested together in a single sublist.
This caused issues because:
1. Not all FWFT features are available on all platforms
2. Some features depend on specific ISA extensions (e.g., pointer_masking
requires Smnpm)
3. Tests would fail if any single feature was unavailable

Add the feature-specific SBI FWFT sublists with the following
improvements:
- Add check_fwft_feature() helper to verify FWFT feature availability
  at runtime
- Update filter_reg() to handle per-feature FWFT register filtering

Subject: [PATCH 2964/5214] power: supply: max17042_battery: Use modern PM ops
 to clear up warning

When building for a platform that does not have power management, such
as s390, there is an unused function warning, as
max17042_suspend_soc_alerts() is only used in max17042_suspend(), which
is under a CONFIG_PM_SLEEP #ifdef.

  drivers/power/supply/max17042_battery.c:957:13: error: 'max17042_suspend_soc_alerts' defined but not used [-Werror=unused-function]
    957 | static void max17042_suspend_soc_alerts(struct max17042_chip *chip)
        |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~

Use the modern DEFINE_SIMPLE_DEV_PM_OPS(), which allows the compiler to
see the functions as used while allowing it to eliminate them as unused
during the optimization phase. Use pm_ptr() to allow the compiler to
drop max17042_pm_ops when there is no PM support.

Subject: [PATCH 2965/5214] perf sched: Cap max_cpu at MAX_CPUS in timehist
 sample processing

perf_timehist__process_sample() updates sched->max_cpu from the
sample CPU without bounds checking.  Later code uses max_cpu + 1 as
an iteration count over arrays allocated with MAX_CPUS entries
(curr_thread, cpu_last_switched).  A recording with CPU IDs >= MAX_CPUS
causes out-of-bounds array accesses.

Also cap the env->nr_cpus_online initialization of max_cpu in
perf_sched__timehist(), which could exceed MAX_CPUS on very large
systems.

Add bounds checks before both max_cpu updates, matching the pattern
already used in map_switch_event().

Subject: [PATCH 2966/5214] perf sched: Fix register_pid() overflow, strcpy,
 and BUG_ON

register_pid() has several issues when processing untrusted perf.data:

1. Integer overflow: (pid + 1) * sizeof(struct task_desc *) can wrap
   to a small value on 32-bit systems when pid is large (e.g.
   0x40000000), causing realloc to return a tiny buffer followed by
   out-of-bounds writes in the initialization loop.

2. Heap buffer overflow: strcpy(task->comm, comm) copies the
   untrusted comm string into a fixed 20-byte COMM_LEN buffer with
   no length check.

3. BUG_ON on allocation failure: perf.data is untrusted input, so
   allocation failures should be handled gracefully rather than
   killing the process.

4. Realloc of sched->tasks assigned directly back, leaking the old
   pointer on failure; nr_tasks incremented before the realloc,
   leaving corrupted state on failure.

Cap pid at PID_MAX_LIMIT (4194304, matching the kernel's maximum
on 64-bit), replace strcpy with strlcpy, guard against NULL comm,
replace BUG_ON with NULL returns using safe realloc patterns, and
add NULL checks in callers that dereference the result.

Subject: [PATCH 2967/5214] perf mmap: Guard cpu__get_node() return in
 aio_bind()

perf_mmap__aio_bind() passes the cpu__get_node() return value directly
to an unsigned long variable (node_index).  When cpu__get_node() returns
-1 for an unknown CPU, the implicit int-to-unsigned-long conversion
sign-extends it to ULONG_MAX.

This causes bitmap_zalloc(ULONG_MAX + 1) which wraps to
bitmap_zalloc(0), returning a zero-sized allocation.  The subsequent
__set_bit(ULONG_MAX, node_mask) then writes massively out of bounds.

Check the return value in a signed temporary before assigning to
node_index, and skip the NUMA binding when the node is unknown.

Subject: [PATCH 2968/5214] perf stat: Bounds-check CPU index in topology
 aggregation callbacks

Six perf_env__get_*_aggr_by_cpu() functions access env->cpu[cpu.cpu]
after only checking cpu.cpu != -1.  env->cpu[] is allocated with
env->nr_cpus_avail entries, so a CPU index from an untrusted perf.data
file that exceeds that count causes an out-of-bounds heap read.

Replace the != -1 guard with >= 0 && < env->nr_cpus_avail in all six
functions.  The >= 0 check also catches -1 and any other negative values
that could bypass the old check.

Affected functions:
  - perf_env__get_socket_aggr_by_cpu()
  - perf_env__get_die_aggr_by_cpu()
  - perf_env__get_cache_aggr_by_cpu()
  - perf_env__get_cluster_aggr_by_cpu()
  - perf_env__get_core_aggr_by_cpu()
  - perf_env__get_cpu_aggr_by_cpu()

Subject: [PATCH 2969/5214] perf c2c: Bounds-check CPU and node IDs before
 bitmap and array access

c2c_he__set_cpu() passes sample->cpu directly to __set_bit(cpu, cpuset)
after only checking for the (u32)-1 sentinel.  The cpuset bitmap is
allocated with c2c.cpus_cnt bits (from env->nr_cpus_avail), so a crafted
perf.data with CPU IDs exceeding that count causes out-of-bounds heap
writes.

c2c_he__set_node() similarly passes the node ID from mem2node__node()
to __set_bit(node, nodeset) after only checking for negative values.
The nodeset bitmap is sized to c2c.nodes_cnt (from env->nr_numa_nodes),
so a node ID exceeding that causes OOB writes.

process_sample_event() indexes c2c.cpu2node[cpu] and
c2c_he->node_stats[node] without bounds checking.  Both arrays are
sized to c2c.cpus_cnt and c2c.nodes_cnt respectively.

Add bounds checks in all three paths:
  - c2c_he__set_cpu(): return if sample->cpu >= c2c.cpus_cnt
  - c2c_he__set_node(): return if node >= c2c.nodes_cnt
  - process_sample_event(): clamp cpu to 0 if >= cpus_cnt,
    guard node_stats access with bounds check

Subject: [PATCH 2970/5214] perf c2c: Bounds-check CPU IDs in setup_nodes()
 topology loop

setup_nodes() iterates CPU maps from the perf.data topology header and
uses cpu.cpu directly as an array index into cpu2node[] (allocated with
c2c.cpus_cnt = env->nr_cpus_avail entries) and __set_bit(cpu.cpu, set)
(bitmap also sized to c2c.cpus_cnt).

A crafted perf.data with topology CPU IDs exceeding nr_cpus_avail causes
out-of-bounds heap writes into both the cpu2node array and the per-node
bitmap.

Add a bounds check to skip CPU IDs that fall outside the valid range.

Subject: [PATCH 2971/5214] perf sched: Clean up idle_threads entry on init
 failure

get_idle_thread() allocates a thread via thread__new() and stores it in
idle_threads[cpu], then calls init_idle_thread() to set up the private
data.  If init_idle_thread() fails (e.g. OOM for the idle_thread_runtime
struct), the function returns NULL but leaves the partially initialized
thread in idle_threads[cpu].

On subsequent calls for the same CPU, get_idle_thread() finds a non-NULL
idle_threads[cpu], skips allocation, and returns thread__get() on a
thread that has no priv data.  Callers then get a thread whose
thread__priv() returns NULL, leading to unexpected behavior.

Release the thread and reset the slot to NULL on init failure so the
entry doesn't persist in a corrupted state.

Subject: [PATCH 2972/5214] perf sched: Use is_idle_sample() for idle thread
 runtime cast guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

timehist_sched_change_event() uses thread__tid(thread) == 0 to decide
whether to cast thread_runtime to idle_thread_runtime.  However, a
crafted perf.data can set common_pid=0 and common_tid=0 (the perf_sample
fields) while prev_pid != 0 (the tracepoint field).  is_idle_sample()
returns false (it checks prev_pid for sched_switch), so
timehist_get_thread() goes through machine__findnew_thread() and returns
the machine's TID 0 thread — whose priv data is a regular thread_runtime,
not the larger idle_thread_runtime allocated by init_idle_thread().

The subsequent cast to idle_thread_runtime reads past the thread_runtime
allocation, accessing itr->last_thread, itr->cursor, and itr->callchain
from adjacent heap memory.  Writing to itr->last_thread corrupts the
heap; calling thread__put() on the OOB value frees an arbitrary pointer.

Replace the thread__tid() == 0 check with is_idle_sample(), which uses
the tracepoint-specific prev_pid field and correctly identifies whether
the sample originated from an idle thread with idle_thread_runtime priv.

of idle hist processing without calling thread__put() first.  The

Use thread__zput() to properly release the reference before clearing

free_idle_threads() calls thread__delete() directly instead of

REFCNT_CHECKING builds, this leaks the pointer handle since
thread__delete() frees the object without going through the refcount
wrapper.

The idle threads are created via thread__new() (refcount=1) in
get_idle_thread().  Callers get additional references via thread__get()
which they release with thread__put().  free_idle_threads() drops the
base reference — thread__put() is the correct call, matching the
thread__new() acquisition.

Subject: [PATCH 2975/5214] perf sched: Replace BUG_ON and add NULL checks in
 replay event helpers

get_new_event() has three issues:

1. The zalloc() result is dereferenced without a NULL check, crashing
   on allocation failure.

2. BUG_ON(!task->atoms) kills the process when realloc() fails.
   Since perf.data is untrusted input, this should be a graceful error.

3. The realloc pattern assigns directly to task->atoms, losing the old
   pointer on failure.  task->nr_events is also incremented before the
   realloc, leaving corrupted state on failure.

Fix get_new_event() to:
  - Check the zalloc() result before dereferencing
  - Use a temporary for realloc() to avoid losing the old pointer
  - Increment nr_events only after successful realloc
  - Return NULL instead of calling BUG_ON on failure

Also fix add_sched_event_wakeup() where zalloc() for wait_sem is
passed to sem_init() without a NULL check.

Update all callers (add_sched_event_run, add_sched_event_wakeup,
add_sched_event_sleep) to handle NULL returns by returning early.
The replay may produce incomplete output on OOM but will not crash.

Subject: [PATCH 2976/5214] perf mmap: Fix NULL deref in aio cleanup on alloc
 failure

perf_mmap__aio_mmap() sets map->aio.nr_cblocks before allocating the
data array.  If calloc() for aiocb or cblocks fails before the data
array is allocated, the return -1 path leads to perf_mmap__aio_munmap()
which loops nr_cblocks times calling perf_mmap__aio_free().  Both
versions of perf_mmap__aio_free() (NUMA and non-NUMA) dereference
map->aio.data[idx] without checking if data is NULL, causing a NULL
pointer dereference.

Add NULL checks for map->aio.data at the top of both
perf_mmap__aio_free() variants so the cleanup path is safe when
allocation fails partway through perf_mmap__aio_mmap().

Introduce perf_env__get_cpu_topology() as a safe accessor that
validates env->cpu, cpu.cpu >= 0, and cpu.cpu < nr_cpus_avail in
one place, returning a struct cpu_topology_map pointer or NULL.
Convert all six topology aggregation callbacks to use it.

Subject: [PATCH 2978/5214] perf c2c: Fix use-after-free in he__get_c2c_hists()
 error path

he__get_c2c_hists() assigns c2c_he->hists before calling
c2c_hists__init().  If init fails, the error path calls free(hists)
but leaves c2c_he->hists pointing to freed memory.  On teardown,
c2c_he_free() finds the non-NULL pointer and calls
hists__delete_entries() on it, causing a use-after-free.

Set c2c_he->hists to NULL before freeing so teardown skips the
already-freed allocation.

Subject: [PATCH 2979/5214] perf timechart: Fix cpu2y() OOB read on untrusted
 CPU index

cpu2y() indexes topology_map[cpu] without bounds checking.  The array
is allocated with nr_cpus entries (from env->nr_cpus_online), but
callers pass sample CPU values from perf.data which can exceed that
size with cross-machine recordings.

Track the topology_map allocation size and bounds-check the CPU
argument in cpu2y() before indexing.  Out-of-bounds CPUs fall back
to the identity mapping (cpu2slot(cpu)), which is the same behavior
as when no topology is available.

Subject: [PATCH 2980/5214] perf tools: Fix int16_t truncation of max_cpu_num
 in set_max_cpu_num()

set_max_cpu_num() assigns the sysfs "possible" CPU count to
max_cpu_num.cpu which is int16_t (struct perf_cpu).  On systems
with >32767 possible CPUs the value silently truncates, potentially
wrapping negative.  This causes cpunode_map to be underallocated
and subsequent cpu__get_node() calls to read out of bounds.

The matching check for max_present_cpu_num was added by commit
c760174401f6 ("perf cpumap: Reduce cpu size from int to int16_t")
but max_cpu_num was missed.  Add the same INT16_MAX guard.

Subject: [PATCH 2981/5214] perf sched: Free callchain nodes in idle thread
 cleanup

free_idle_threads() relies on the thread priv destructor (free()) to
clean up idle_thread_runtime structs.  But free() doesn't walk the
callchain_cursor linked list or the callchain_root tree allocated
by callchain_cursor__copy() and callchain_append() during --idle-hist
processing.  Every idle thread with callchain data leaks these nodes.

Introduce callchain_cursor_cleanup() to free the cursor's linked list
of callchain_cursor_node entries, and call it together with
free_callchain() in free_idle_threads() before thread__put().

Subject: [PATCH 2982/5214] libperf: Document struct perf_cpu int16_t ABI
 limitation

struct perf_cpu.cpu is int16_t, limiting perf to 32767 CPUs.  This is
part of the libperf ABI (returned by value from perf_cpu_map__cpu() and
friends), so widening it requires an ABI bump.

Add a comment on the struct definition noting this, and create a TODO
file to collect future ABI changes so they can be batched into a single
version bump.

+Future ABI changes
+==================
+
+This file collects items that require a libperf ABI bump.  Each entry
+should describe the current limitation, the desired end state, and the
+scope of the change so that a future ABI revision can batch them
+together.
+
+1. Widen struct perf_cpu.cpu from int16_t to int
+   - Current limit: 32767 CPUs.  No architecture exceeds this today
+     (x86_64 max is 8192, arm64 is 4096), but NR_CPUS limits keep
+     growing.  perf clamps to INT16_MAX in set_max_cpu_num() as a
+     safety net.
+   - Scope: struct perf_cpu is embedded everywhere — perf_cpu_map__cpu(),
+     perf_cpu_map__min(), perf_cpu_map__max(), perf_cpu_map__has(), the
+     for_each_cpu macros, and all internal callers.  The perf_cpu_map
+     internal array (RC_CHK_ACCESS(map)->map[]) stores struct perf_cpu
+     directly.  Widening changes the struct layout and every function
+     that returns or accepts struct perf_cpu by value.
+   - Migration: bump LIBPERF version in libperf.map, audit all
+     sizeof(struct perf_cpu) assumptions, update perf.data
+     serialization if needed.

Subject: [PATCH 2984/5214] Input: apbps2 - simplify resource mapping and IRQ
 retrieval

Simplify resource mapping by using devm_platform_ioremap_resource()
instead of the longer devm_platform_get_and_ioremap_resource() helper
as the last argument is NULL.

Additionally, use platform_get_irq() to retrieve the interrupt
instead of irq_of_parse_and_map() and propagate its error code on
failure. irq_of_parse_and_map() requires irq_dispose_mapping, which is
missing.

Subject: [PATCH 2985/5214] Input: atlas_btns - modernize the driver

Rework the driver to use modern style:

- Remove global state by introducing a per-device structure
- Use devm for resource management (input device allocation)
- Use dev_err_probe() for error reporting in the probe path
- Clean up unused definitions and headers.

Subject: [PATCH 2988/5214] clk: qcom: videocc-x1p42100: Add support for video
 clock controller

Add support for the video clock controller for video clients to be
able to request for videocc clocks on X1P42100 platform. Although
X1P42100 is derived from X1E80100, the video clock controller differs
significantly. The BSE clocks are newly added, several cdiv clocks have
been removed, and most RCG frequency tables have been updated. Initial
PLL configurations also require changes, hence introduce a separate
videocc driver for X1P42100 platform.

Subject: [PATCH 2989/5214] clk: qcom: camcc-x1e80100: Add support for camera
 QDSS debug clocks

Add support for camera QDSS debug clocks on X1E80100 platform which
are required to be voted for camera icp and cpas usecases. This change
aligns the camcc driver to the new ABI exposed from X1E80100 camcc
bindings that supports these camcc QDSS debug clocks.

Add support for the camera clock controller for camera clients to
be able to request for camcc clocks on X1P42100 platform. Although
X1P42100 is derived from X1E80100, the camera clock controller driver
differs significantly. Few PLLs, clocks and GDSC's are removed, there
is delta in frequency tables for most RCG's and parent data structures
also changed for few RCG's. Hence introduce a separate camcc driver
for X1P42100 platform.

Subject: [PATCH 2993/5214] clk: qcom: gdsc: Support enabling interconnect path
 for power domain

On newer SoCs like Milos the CAMSS_TOP_GDSC power domains requires the
enablement of the multimedia NoC, otherwise the GDSC will be stuck on
'off'.

Add support for getting an interconnect path as specified in the SoC
clock driver, and enabling/disabling that interconnect path when the
GDSC is being enabled/disabled.

Subject: [PATCH 2998/5214] riscv: pi: replace strlcat with strscpy in
 get_early_cmdline

Use the return value of strscpy() instead of calling strlen(fdt_cmdline)
again and return early on string truncation. Drop the explicit size
argument since early_cmdline has a fixed length, which strscpy()
determines using sizeof() when the argument is omitted.

Replace strlcat() with strscpy() to append CONFIG_CMDLINE.

Also remove the unnecessary fdt_cmdline NULL initialization.

Subject: [PATCH 2999/5214] riscv: use sysfs_emit in cpu_show_ghostwrite

Replace sprintf() with sysfs_emit() in cpu_show_ghostwrite(), which is
preferred for formatting sysfs output because it provides safer bounds
checking.

While the current code only emits fixed strings that fit easily within
PAGE_SIZE, use sysfs_emit() to follow secure coding best practices.

Subject: [PATCH 3000/5214] riscv: propagate insert_resource result from
 add_resource

Currently, add_resource() returns 1 on success, even though its callers
only check for negative values. Instead, propagate the insert_resource()
result from add_resource() to align with standard kernel return-value
conventions (0 on success, negative errno on failure).

Use %pR to print the full resource range while at it.

Subject: [PATCH 3001/5214] selftests/riscv: fix compiler output flag spacing
 in all Makefiles

Standardize the compiler output flag format across all RISC-V
selftests by adding a space between '-o' and '$@'.

Although '-o$@' is perfectly valid for GCC/Clang to parse,
changing it to '-o $@' with a space aligns with the GNU
official documentation conventions, improves readability by
visually separating the flag from the target variable, and
ensures consistency with other architectures.

Currently, RISC-V selftests use '-o$@' (without space) in 13
instances across 6 Makefiles, while all other architectures
consistently use '-o $@' (with space). This inconsistency makes
RISC-V an outlier in the kernel's selftest infrastructure.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The generic CC_CAN_LINK detection relies on -m32/-m64 compiler flags.
These are not supported by riscv compilers.

Use architecture-specific logic using -mabi instead.

Prefer the 'd' ABI variant when possible as todays toolchains are most
likely to provide a libc for that one.

Subject: [PATCH 3003/5214] riscv: Fix ftrace_graph_ret_addr() to use the
 correct task pointer

The walk_stackframe() function is used to unwind the stack of a given
task. When function graph tracing is enabled, ftrace_graph_ret_addr()
is called to resolve the original return address if it was modified by
the tracer.

The current code incorrectly passes 'current' instead of 'task' to
ftrace_graph_ret_addr(). This causes incorrect return address resolution
when unwinding a stack of a different task (e.g., when the task is
blocked in __switch_to).

Fix this by passing 'task' instead of 'current' to match the behavior
of other architectures (arm64, loongarch, powerpc, s390, x86).

Subject: [PATCH 3004/5214] riscv: module: Use generic cmp_int() instead of
 custom cmp_3way()

The module-sections.c file defines a custom cmp_3way() macro to perform
3-way comparisons during relocation sorting.

Instead of maintaining our own implementation, use the generic
cmp_int() macro provided by the already included <linux/sort.h>. This
removes redundant code and relies on standard kernel interfaces.

Subject: [PATCH 3005/5214] riscv: Implement _THIS_IP_ using inline asm

Both GCC [1] and Clang [2] consider the generic version of _THIS_IP_ to
be broken:

        #define _THIS_IP_  ({ __label__ __here; __here: (unsigned long)&&__here; })

In particular, the address of a label is only expected to be used with a
computed goto.

While the generic version more or less works today, it is known to be
brittle and may break with current and future optimizations. For
example, Clang -O2 always returns 1 when this function is inlined:

        static inline unsigned long get_ip(void)
        { return ({ __label__ __here; __here: (unsigned long)&&__here; }); }

Fix it by overriding _THIS_IP_ in <asm/linkage.h> (which is included by
<linux/instruction_pointer.h>) using an architecture-specific inline asm
version. Additionally, avoiding taking the address of a label prevents
compilers from emitting spurious indirect branch targets (e.g. ENDBR or
BTI) under control-flow integrity schemes.

Subject: [PATCH 3006/5214] Input: ims-pcu - only expose sysfs attributes on
 control interface

When the driver was converted to use the driver core to instantiate device
attributes (via .dev_groups in the usb_driver structure), the attributes
started appearing on all interfaces bound to the driver. Since the ims-pcu
driver manually claims the secondary data interface during probe, the
driver core automatically creates the sysfs attributes for that interface
as well.

However, the driver only supports these attributes on the primary control
interface. Data interfaces lack the necessary descriptors and internal
state to handle these requests, and accessing them can lead to unexpected
behavior or crashes.

Fix this by updating the is_visible() callbacks for both the main and OFN
attribute groups to verify that the interface being accessed is indeed the
control interface.

ims_pcu_reset_packet() incorrectly sets have_stx to true, which implies
that the start-of-packet delimiter has already been received. This
causes the protocol parser to skip waiting for the next STX byte and
potentially process garbage data.

Subject: [PATCH 3015/5214] Input: ims-pcu - fix DMA mapping violation in line
 setup

In ims_pcu_line_setup(), the driver uses pcu->cmd_buf as a transfer
buffer for usb_control_msg(). However, pcu->cmd_buf is embedded in the
struct ims_pcu allocation, which violates DMA mapping rules regarding
cacheline alignment.

Use a heap-allocated buffer for the line coding data instead.

Subject: [PATCH 3016/5214] Input: ims-pcu - add response length checks

The driver processes response data from device buffers without verifying
that the device actually sent enough data. This can lead to
out-of-bounds reads or processing stale data.

Add checks for the expected response length before accessing the
buffers.

Subject: [PATCH 3017/5214] Input: ims-pcu - fix potential infinite loop in CDC
 union descriptor parsing

The driver parses CDC union descriptors in ims_pcu_get_cdc_union_desc()
by iterating through the extra descriptor data. However, it does not
verify that the bLength of each descriptor is at least 2. A malicious
device could provide a descriptor with bLength = 0, leading to an
infinite loop in the driver.

Add a check to ensure bLength is at least 2 before proceeding with
parsing.

Subject: [PATCH 3018/5214] KVM: riscv: Check hugetlb block mappings against
 memslot bounds

RISC-V KVM has used the hugetlb VMA size directly as the G-stage
mapping size since stage-2 page table support was added. That is safe
only if the block covered by the fault is fully contained in the
memslot and the userspace address has the same offset as the GPA
within that block.

The THP path already checks those constraints before installing a PMD
block mapping. The hugetlb path did not, so an unaligned memslot could
make KVM install a PMD or PUD sized G-stage block that covers memory
outside the slot or maps the wrong host pages.

Pass the target mapping size into fault_supports_gstage_huge_mapping().
The same helper can be used for both THP PMD mappings and hugetlb
PMD/PUD mappings.

Select hugetlb mapping sizes through the same memslot-boundary check,
falling back from PUD to PMD to PAGE_SIZE. When a smaller hugetlb
mapping size is selected, fault the GFN aligned to that selected size
instead of the original VMA size.

Also keep hugetlb mappings out of transparent_hugepage_adjust(). Once
the hugetlb path has chosen PAGE_SIZE, promoting it again through the
THP helper would miss the hugetlb fallback decision.

Subject: [PATCH 3020/5214] KVM: selftests: Add a hugetlb memslot alignment
 test mode

kvm_page_table_test can already exercise hugetlb-backed guest memory,
but it always creates the test memslot with GPA alignment matching the
hugetlb backing size. That misses the case where a valid hugetlb
memslot is later moved so that the memslot GPA and HVA no longer have
the same offset within the backing huge page.

Add a -u option that moves the test memslot GPA by one guest page after
creating the hugetlb memslot. The memslot is created through the normal
helper first, so the backing allocation remains valid and hugetlb aligned.
Moving the memslot then creates a deliberate HVA/GPA offset mismatch
before the guest mapping is installed.

This mode is useful for checking that architecture MMUs do not install
a block mapping when the block would map the wrong host pages or cover
memory outside the memslot. The option is restricted to hugetlb-backed
test memory because it's specifically about hugetlb block mapping
eligibility.

RANDOMIZE_BASE currently selects RELOCATABLE even though RELOCATABLE
is visible to users. Some other architectures, like x86, use 'depends on'
for RELOCATABLE in their definition of RANDOMIZE_BASE, so let's do the same
here.

This select-visible Kconfig misusage was detected by Kconfirm, a static

Subject: [PATCH 3023/5214] riscv: ftrace: select HAVE_BUILDTIME_MCOUNT_SORT

RISC-V already satisfies all prerequisites for build-time mcount sorting:
the sorttable host tool handles EM_RISCV in its machine-type dispatch, and
the __mcount_loc section entries are stored as direct virtual addresses in
the final vmlinux binary, so no relocation processing is required during
the sort step.

Select HAVE_BUILDTIME_MCOUNT_SORT so that BUILDTIME_MCOUNT_SORT is
automatically enabled when DYNAMIC_FTRACE is configured.  This allows
sorttable to sort the __mcount_loc section at link time, making the
run-time ftrace initialisation path skip the software sort and reducing
kernel startup overhead.

Verified with CONFIG_FTRACE_SORT_STARTUP_TEST=y, which confirms that
the section produced by the build is already in ascending order:

Subject: [PATCH 3025/5214] riscv: cpu_ops: Change return value type of
 cpu_is_stopped() to bool

In the original sbi_cpu_is_stopped(), if rc doesn't equal to the
SBI_HSM_STATE_STOPPED, it will return rc to the caller directly. But
there is a hidden problem, the rc could be SBI_HSM_STATE_STARTED, if
so, this function will report cpu stopped while the cpu isn't really
stopped.

Furthermore, from the name of cpu_is_stopped(), it gives a sense the
return value is a bool type, true means the cpu is stopped, conversely
false means the cpu is not stopped.

Here change the return value type to bool and change the callers
accordingly. This could fix the above two issues.

On RISC-V, the actual mappable range of physical address space is

Define the DIRECT_MAP_PHYSMEM_END macro based on the existing virtual
address space layout macros to expose this information to
get_free_mem_region(). Otherwise, it returns a region that couldn't be

Subject: [PATCH 3029/5214] riscv: kexec_file: Constrain segment placement to
 direct map

When kexec_file_load places segments with buf_max=ULONG_MAX and
top_down=true, they land at the highest available physical addresses.
On RISC-V the size of the linear mapping is determined by the active
VM mode: SV39 caps the direct map at roughly 128GB, while SV48/SV57
extend the range substantially further. When the installed physical
memory exceeds the direct map size of the active mode, top-down
placement puts DTB/initrd at physical addresses outside the linearly
mapped region. The kexec'd kernel cannot reach them during early
boot, triggering a page fault at memcmp in start_kernel.

Fix by constraining buf_max to PFN_PHYS(max_low_pfn), which reflects
the runtime direct map boundary for the active VM mode (SV39/SV48/
SV57). This keeps all kexec segments within the linearly mapped
region while preserving the upstream top_down allocation strategy.

Subject: [PATCH 3030/5214] riscv: cacheinfo: Fix node reference leak in
 populate_cache_leaves

Currently, the while loop drops the reference to prev in each iteration.
If the loop terminates early due to a break, the final of_node_put(np)
correctly drops the reference to the current node.

However, if the loop terminates naturally because np == NULL, calling
of_node_put(np) is a no-op. This leaves the last valid node stored in
prev without its reference dropped, resulting in a node reference leak.

Fix this by changing the final `of_node_put(np)` to `of_node_put(prev)`.

Subject: [PATCH 3031/5214] riscv: stacktrace: Remove bogus -0x4 offset in
 non-FP walk_stackframe

In the non-frame-pointer version of walk_stackframe, each value read
from the stack is treated as a potential return address and has 0x4
subtracted before being used as the program counter. This was intended
to convert the return address (the instruction after a call) back to
the call site, but it is incorrect:

1. RISC-V has variable-length instructions due to the RVC (compressed
   instruction) extension. A call instruction can be either 4 bytes
   (regular) or 2 bytes (compressed, e.g. c.jal). Subtracting a fixed
   0x4 assumes all call instructions are 4 bytes, which is wrong for
   compressed instructions.

2. Stack traces conventionally report return addresses, not call sites.
   Other architectures (ARM64, x86, ARM) do not subtract instruction
   size from return addresses in their stack unwinding code.

3. The frame-pointer version of walk_stackframe already dropped the
   -0x4 offset. Commit b785ec129bd9 ("riscv/ftrace: Add
   HAVE_FUNCTION_GRAPH_RET_ADDR_PTR support") replaced "pc =
   frame->ra - 0x4" with ftrace_graph_ret_addr(), and the commit
   message explicitly noted that "the original calculation, pc =
   frame->ra - 4, is buggy when the instruction at the return address
   happened to be a compressed inst." The non-FP version was simply
   overlooked.

Remove the bogus -0x4 offset to match the FP version and the
conventions used by other architectures.

Subject: [PATCH 3033/5214] riscv: kfence: Call mark_new_valid_map() for
 kfence_unprotect()

In kfence_protect_page(), which kfence_unprotect() calls, we cannot send
IPIs to other CPUs to ask them to flush TLB. This may lead to those CPUs
spuriously faulting on a recently allocated kfence object despite it
being valid, leading to false positive use-after-free reports.

Fix this by calling mark_new_valid_map() so that the page fault handling
code path notices the spurious fault and flushes TLB then retries the
access.

Update the comment in handle_exception to indicate that
new_valid_map_cpus_check also handles kfence_unprotect() spurious
faults.

Note that kfence_protect() has the same stale TLB entries problem, but
that leads to false negatives, which is fine with kfence.

Subject: [PATCH 3036/5214] riscv: mm: Unconditionally sfence.vma for spurious
 fault

Svvptc does not guarantee that it's safe to just return here. Since we
have already cleared our bit, if, theoretically, the bounded timeframe
for the accessed page to become valid still hasn't happened after sret,
we could fault again and actually crash.

Hopefully, these spurious faults should be rare enough that this is an
acceptable slowdown.

Subject: [PATCH 3037/5214] RISC-V: KVM: Fix skip of valid pages in
 kvm_riscv_gstage_wp_range

The current gstage range walker unconditionally advances by 'page_size'
when a leaf PTE is not found, e.g. when the range to wp is
[0xfffff01fc000, 0xfffff023c000) and page_size is 2MB, if found_leaf of
0xfffff01fc000 returns false, it skip the whole range, but it's possible
to have valid entries in [0xfffff0200000, 0xfffff023c000).

 kvm_riscv_gstage_unmap_range

Same as kvm_riscv_gstage_wp_range, the possible valid pages should not
be skipped if !found_leaf. Different from wp case, which can
write-protect more than asked, unmap can't do that, no splitting is
added right now but a warning is logged instead.

Subject: [PATCH 3046/5214] KVM: arm64: Clear __hyp_running_vcpu when flushing
 the pKVM hyp vCPU

flush_hyp_vcpu() copies the host vCPU context into the hyp's private
vCPU on every run. ctxt_to_vcpu() expects a guest context to have a
NULL __hyp_running_vcpu, which is only ever set on the host context, so
that it resolves the vCPU via container_of(). While this is generally
the case, flush_hyp_vcpu() copies the context verbatim and does not
enforce this, so a value provided by the host is dereferenced at EL2
(host -> EL2).

Fix by clearing __hyp_running_vcpu after the copy.

flush_hyp_vcpu() copies the host vGIC state into the hyp's private vCPU
on every run. The vGIC list register save and restore use used_lrs as
their loop bound and expect it to stay within the number of implemented
list registers. While this is generally the case, flush_hyp_vcpu()
copies vgic_v3 verbatim and does not enforce this, so a value provided
by the host is used at EL2 to index vgic_lr[] and access ICH_LR<n>_EL2
(host -> EL2).

Fix by clamping used_lrs to the number of implemented list registers
after the copy, as the trusted path already does in
vgic_flush_lr_state(). The number of implemented list registers is
constant after init, so it is replicated once from
kvm_vgic_global_state.nr_lr into hyp_gicv3_nr_lr rather than read on
every entry.

Subject: [PATCH 3048/5214] KVM: arm64: Flush HCR_EL2.VSE to deliver SErrors to
 pKVM guests

With pKVM enabled, the host injects a virtual SError by setting
HCR_EL2.VSE on its vCPU copy, but flush_hyp_vcpu() only flows TWI/TWE
into the hyp vCPU that runs, so VSE never reaches it and a deferred
(masked) SError is never delivered. VSE is a host-owned injection
control, not a trap-configuration bit, so restricting the host's
trap-register values should not have dropped it.

Flow it on entry; sync_hyp_vcpu() already copies hcr_el2 back, so
delivery is reflected to the host. THis makes it consistent with
the existing forwarding of VSESR_EL2, which qualifies the Serror.

Subject: [PATCH 3049/5214] KVM: arm64: Free hyp-share tracking node when share
 hypercall fails

share_pfn_hyp() inserts a tracking node into hyp_shared_pfns and
then invokes __pkvm_host_share_hyp. If the hypercall rejects the
share (page-state mismatch at EL2), the node stays in the tree
with refcount 1: a phantom share that leaks the allocation and
that a later unshare will trust.

Erase the node and free it on hypercall failure.

Subject: [PATCH 3050/5214] KVM: arm64: Avoid host/hyp share desync on unshare
 hypercall failure

unshare_pfn_hyp() erases the tracking node from hyp_shared_pfns
and frees it before invoking __pkvm_host_unshare_hyp. If the
hypercall fails (e.g. EL2 refcount still held, or page-state
mismatch), the host loses its record while EL2 still holds the
share, breaking later share/unshare attempts on the same pfn.

Invoke the hypercall first; erase and free only on success.

Document at the kvm_unshare_hyp() call site that the WARN_ON() is
left non-fatal: a failed unshare leaks the page (it stays shared
with the hypervisor) but breaks no isolation guarantee.

kvm_share_hyp() shares a range one page at a time. If share_pfn_hyp()

shared, while the caller treats the whole range as failed and never
unshares them.

Unshare those pages before returning the error. If an unshare itself
fails the page is leaked: it stays shared with the hypervisor and is
no longer reusable for pKVM, but no isolation guarantee is broken, so
WARN and continue. Not expected in practice.

Create hyperv subdirectory under drivers/iommu in anticipation of more
Hyper-V related files from upcoming PCI passthrough and PV-IOMMU patches.
Also, the current file hyperv-iommu.c actually implements irq remapping on
x86, so rename to more appropriate hv-irq-remap-x86.c and move it under
the new hyperv subdirectory. Since this file implements irq_remap_ops
exposed by drivers/iommu/irq_remapping.h, it cannot be relocated to the
irq directory. This is in sync with other backend directories like amd
and intel there.

Lastly, this file should not be tied to CONFIG_HYPERV_IOMMU, but to
CONFIG_HYPERV and CONFIG_IRQ_REMAP.

Subject: [PATCH 3055/5214] x86/hyperv: Cosmetic changes in irqdomain.c for
 readability

Make cosmetic changes:
 o Rename struct pci_dev *dev to *pdev since there are cases of
   struct device *dev in the file and all over the kernel
 o Rename hv_build_pci_dev_id to hv_build_devid_type_pci in anticipation
   of building different types of device ids
 o Fix checkpatch.pl issues with return and extraneous printk
 o Replace spaces with tabs
 o Rename struct hv_devid *xxx to struct hv_devid *hv_devid given code
   paths involve many types of device ids
 o Fix indentation in a large if block by using goto.

There are no functional changes.

Subject: [PATCH 3057/5214] mshv: add bounds check on vp_index in
 mshv_intercept_isr()

mshv_intercept_isr() extracts vp_index from the hypervisor message
payload and uses it directly to index into pt_vp_array without
validation. handle_bitset_message() and handle_pair_message() already
validate vp_index against MSHV_MAX_VPS before array access.

Add the same MSHV_MAX_VPS bounds check for consistency with the other
message handlers.

Fixes: 621191d709b1 ("Drivers: hv: Introduce mshv_root module to expose /dev/mshv to VMMs")

Subject: [PATCH 3058/5214] pinctrl: Move Airoha driver to dedicated directory

In preparation for additional SoC support, move the Airoha pinctrl driver
for AN7581 SoC to a dedicated directory.

This is to tidy things up and keep code organized without polluting the
Mediatek driver directory.

The driver doesn't depend on any generic or common code from the Mediatek
codebase so it can be safely moved without any modification.

Subject: [PATCH 3059/5214] pinctrl: aspeed: Fix GPIO mux value for ADC-capable
 balls

aspeed_g7_soc1_gpio_request_enable() unconditionally writes mux
function 0 to route the requested pin to GPIO. This is wrong for the
ADC-capable balls W17 through AB19 (ADC0-ADC15), where function 0
selects the ADC input and function 1 selects GPIO. Requesting one of
those GPIOs therefore muxed the ball to ADC instead.

Write mux value 1 for balls W17 through AB19 so the GPIO function is
actually selected.

Subject: [PATCH 3060/5214] pinctrl: qcom: lpass-lpi: Enable runtime PM hooks
 on LPASS LPI SoCs

The LPASS LPI core conversion to PM clock framework relies on variant
drivers wiring runtime PM callbacks.

Hook up runtime PM callbacks for the LPASS LPI variant drivers touched
in this patch so they are prepared for the shared core conversion.

This commit is a preparatory NOP on its own, as runtime PM is still
disabled on these devices until the following core conversion patch.

This is a mechanical per-variant driver update that relies on the
same generic PM clock flow (of_pm_clk_add_clks() + pm_clk_suspend/
pm_clk_resume()) and DT-provided clocks.

Runtime behavior was validated on Kodiak (sc7280).

Subject: [PATCH 3061/5214] pinctrl: qcom: lpass-lpi: Switch to PM clock
 framework for runtime PM

Convert the LPASS LPI pinctrl driver to use the PM clock framework for
runtime power management.

This allows the LPASS LPI pinctrl driver to drop clock votes when idle,
improves power efficiency on platforms using LPASS LPI island mode, and
aligns the driver with common runtime PM patterns used across Qualcomm
LPASS subsystems.

Guard GPIO register read/write helpers and slew-rate register programming
with synchronous runtime PM calls so the device is active during MMIO
operations whenever autosuspend is enabled.

Make PINCTRL_LPASS_LPI depend on PM_CLK, since this patch introduces
direct PM clock API use in the shared core.

Subject: [PATCH 3063/5214] powerpc/entry: Disable interrupts before
 irqentry_exit

Venkat reported a panic on powerpc-next tree where GENERIC_ENTRY has
been enabled.

kernel BUG at kernel/sched/core.c:7512!
NIP  preempt_schedule_irq+0x44/0x118
LR   dynamic_irqentry_exit_cond_resched+0x40/0x1a4
Call Trace:
 dynamic_irqentry_exit_cond_resched+0x40/0x1a4
 do_page_fault+0xc0/0x104
 data_access_common_virt+0x210/0x220

This happens since __do_page_fault ends up enabling the interrupts and
it could take significant time such that need_resched could be set. This
leads to schedule call in irqentry_exit leading to the bug.

There are many such irq handlers which enables the interrupts.
Fix it by disabling the irq before calling irqentry_exit. The same
pattern exists today in interrupt_exit_kernel_prepare.

Subject: [PATCH 3064/5214] powerpc: Simplify access_ok()

With the implementation of masked user access, we always have a memory
gap between user memory space and kernel memory space, so use it to
simplify access_ok() by relying on access fault in case of an access
in the gap.

Most of the time the size is known at build time.

On powerpc64, the kernel space starts at 0x8000000000000000 which is
always more than two times TASK_USER_MAX so when the size is known at
build time and lower than TASK_USER_MAX, only the address needs to be
verified. If not, a binary or of address and size must be lower than
TASK_USER_MAX. As TASK_USER_MAX is a power of 2, just check that
there is no bit set outside of TASK_USER_MAX - 1 mask.

On powerpc32, there is a garanteed gap of 128KB so when the size is
known at build time and not greater than 128KB, just check that the
address is below TASK_SIZE. Otherwise use the original formula.

Subject: [PATCH 3065/5214] thunderbolt: debugfs: Fix sideband write size check

sb_regs_write() looks up the matching sideband register entry before
validating the number of bytes to write.

However, the size check uses sb_regs->size, which is the size of the
first entry in the register table, instead of the matched entry. This
rejects valid writes to larger sideband registers such as USB4_SB_DEBUG
or USB4_SB_DATA.

Use the matched register entry for the size check.

Subject: [PATCH 3067/5214] dmaengine: tegra210-adma: Add error logging on
 failure paths

Add dev_err/dev_err_probe logging across failure paths to improve
debuggability of DMA errors during runtime and probe.

Use return dev_err_probe() pattern where no cleanup is required in the
probe function. On error paths that need explicit unwind, store the
dev_err_probe() return value in ret before jumping to the cleanup label.
Also convert existing dev_err calls in probe to dev_err_probe for
consistency, and use dev_err in non-probe functions.

Keep explicit runtime PM and DMA registration unwind instead of managed or
scoped cleanup. The scoped runtime PM guard releases the usage count with
pm_runtime_put(), while this probe error path needs pm_runtime_put_sync()
before pm_runtime_disable(). The OF DMA registration failure path also
needs to unregister the DMA engine before dropping the runtime PM reference.

Subject: [PATCH 3068/5214] dmaengine: ste_dma40: turn d40_base phy_chans into
 a flexible array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Convert the separately-offset phy_chans pointer to a C99 flexible array
member at the end of struct d40_base, and switch the allocation to
struct_size(). The log_chans and memcpy_chans slots continue to live
in the same allocation immediately after phy_chans, indexed via
base->log_chans. This removes the hand-rolled pointer fixup that
recomputed phy_chans from base + ALIGN(sizeof(struct d40_base), 4).

The ALIGN(sizeof(struct d40_base), 4) requirement is met implicitly by the
C compiler when using a flexible array member. With struct d40_chan
phy_chans[] as the last member, the C standard guarantees
sizeof(struct d40_base) includes trailing padding to satisfy the alignment
of the flexible array element type (struct d40_chan). Since struct d40_chan
contains members like spinlock_t, pointers, and struct dma_chan — all with
alignment ≥ 4 — the compiler ensures sizeof(struct d40_base) is already a
multiple of _Alignof(struct d40_chan) >= 4. The struct_size() macro then
computes sizeof(struct d40_base) + sizeof(struct d40_chan) * num_phy_chans,
so phy_chans[0] lands at a properly aligned offset without needing the manual
ALIGN.

 variable declaration

Combining the struct definition with its variable initializer confuses the
kernel-doc parser because __MUTEX_INITIALIZER() expands to contain braces,
breaking brace counting and causing:

  Warning: drivers/dma/dmatest.c:152 struct member '' not described in 'dmatest_info'

Split into separate struct definition and variable declaration, which is
the standard kernel pattern.

Subject: [PATCH 3075/5214] dmaengine: sh: rz-dmac: Add DMA ACK signal routing
 support

Some peripherals on RZ/G3E SoCs (SSIU, SPDIF, SCU/SRC, DVC, PFC) require
explicit ACK signal routing through the ICU for level-based DMA handshaking.

Rather than extending the DT binding with an optional second #dma-cells
(which would require all DMA consumers to supply two cells even when ACK
routing is not needed), derive the ACK signal number directly from the
MID/RID request number using the linear mapping defined in RZ/G3E hardware
manual Table 4.6-28:

  PFC external DMA pins (DREQ0..DREQ4):
    req_no 0x000-0x004 -> ACK No. 84-88

  SSIU BUSIFs (ssip00..ssip93):
    req_no 0x161-0x198 -> ACK No. 28-83

  SPDIF (CH0..CH2) + SCU SRC (sr0..sr9) + DVC (cmd0..cmd1):
    req_no 0x199-0x1b4 -> ACK No. 0-27

ACK routing is programmed when a channel is prepared for transfer and
cleared when the channel is released or the transfer times out, following
the same pattern as MID/RID request routing.

dw_edma_pcie_probe() treats the PCI device ID driver_data as the
template for the controller layout and copies it unconditionally. A
device bound dynamically via sysfs can match the driver without that
data, which leads to a NULL pointer dereference.

Reject such matches before enabling the device.

 DONE_INT_MASK and ABORT_INT_MASK

The DONE_INT_MASK and ABORT_INT_MASK registers are shared by all DMA
channels, and modifying them requires a read-modify-write sequence.
Because this operation is not atomic, concurrent calls to
dw_edma_v0_core_start() can introduce race conditions if two channels
update these registers simultaneously.

Add a spinlock to serialize access to these registers and prevent race
conditions.

Subject: [PATCH 3081/5214] dmaengine: dma-axi-dmac: use DMA pool to manange
 DMA descriptor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For architectures like Microblaze or arm64 (where this IP is used),
DMA_DIRECT_REMAP is set which means that dma_alloc_coherent() might
remap (and hence vmalloc()) some memory. This became visible in a design
where dma_direct_use_pool() is not possible.

With the above, when calling dma_free_coherent(), vunmap() would be
called from softirq context and thus leading to a BUG().

To fix it, use a dma pool that is allocated in
.device_alloc_chan_resources() and allocate blocks from it. The key
point is that now dma_pool_free() is used in axi_dmac_free_desc() to
free the blocks and that just frees the blocks from the pool in the
sense they can be used again. In other words, no actual call to
dma_free_coherent() happens. That only happens when destroying the pool
in axi_dmac_free_chan_resources() which does not happen in any interrupt
context.

Subject: [PATCH 3083/5214] dmaengine: tegra: Fix burst size calculation

Currently, the Tegra GPC DMA hardware requires the transfer length to
be a multiple of the max burst size configured for the channel. When a
client requests a transfer where the length is not evenly divisible by
the configured max burst size, the DMA hangs with partial burst at
the end.

Fix this by reducing the burst size to the largest power-of-2 value
that evenly divides the transfer length. For example, a 40-byte
transfer with a 16-byte max burst will now use an 8-byte burst
(40 / 8 = 5 complete bursts) instead of causing a hang.

This issue was observed with the PL011 UART driver where TX DMA
transfers of arbitrary lengths were stuck.

Subject: [PATCH 3084/5214] firmware: stratix10-rsu: avoid blocking
 reboot_image sysfs when busy

Writes to the reboot_image sysfs attribute went through rsu_send_msg(),
which unconditionally takes priv->lock with mutex_lock(). If another RSU
operation is in flight (e.g. a DCMF status query from probe or a
concurrent sysfs read path), userspace writers get stuck in the kernel
waiting on the mutex instead of being told the device is busy.

Split rsu_send_msg() into an inner __rsu_send_msg_locked() helper that
performs the SMC transaction with the caller holding priv->lock, plus
two thin wrappers: rsu_send_msg() preserves the original blocking
behaviour for existing callers, and rsu_try_send_msg() uses
mutex_trylock() and returns -EBUSY immediately when the lock is held.

Use rsu_try_send_msg() from reboot_image_store() so the write returns
-EBUSY without blocking when an RSU operation is already running.
Userspace can retry on -EBUSY. No functional change for other sysfs
attributes.

This keeps blocking rsu_send_msg() for existing callers, add
rsu_try_send_msg() with -EBUSY only for reboot_image_store(). That
matches the original goal (avoid a second reboot_image write blocking
behind priv->lock) without changing sysfs behaviour for the other
attributes. The earlier idea of using mutex_trylock() in all of
rsu_send_msg() and returning -EAGAIN would have been harder to justify
for userspace (echo does not retry on that).

Tze Yee tested the patch on an Agilex SoC devkit.

[Test 1] Idle reboot_image write (success path)
Result:
   # insmod stratix10-rsu.ko
   # echo 0x01000000 > .../reboot_image
   # echo "exit=$?"
   exit=0
   # ./rsu_client --log
         VERSION: 0x00000202
           STATE: 0x00000000
   CURRENT IMAGE: 0x0000000001000000
      FAIL IMAGE: 0x0000000000000000
       ERROR LOC: 0x00000000
   ERROR DETAILS: 0x00000000
   RETRY COUNTER: 0x00000000
   Operation completed

[Test 2] reboot_image while priv->lock is held (-EBUSY path)
To get a deterministic busy window without flooding the service layer,
add a local debug helper (module parameter debug_hold_lock_sec +
kthread that holds priv->lock for N seconds after probe).

Result:
   # insmod stratix10-rsu.ko debug_hold_lock_sec=60
   [  121.220904] stratix10-rsu stratix10-rsu.0: TEST: RSU lock held for
60 s - try reboot_image now
   # echo 0x01000000 > .../reboot_image
   -sh: echo: write error: Device or resource busy
   # echo "during hold: exit=$?"
   during hold: exit=1
   [  183.268706] stratix10-rsu stratix10-rsu.0: TEST: RSU lock released
   # echo 0x01000000 > .../reboot_image
   # echo "after release: exit=$?"
   after release: exit=0

Together, these results match the intended behaviour: reboot_image
fails fast with -EBUSY when the RSU mutex is already held, and
succeeds once the lock is available.

Subject: [PATCH 3085/5214] firmware: stratix10-svc: Add support to query Arm
 Trusted Firmware (ATF) version

Add entry in Stratix10 service layer that allow client to retrieve the ATF
version at runtime, which is useful for system diagnostics, compatibility
checks, and ensuring the correct secure firmware is in use.

The change introduces:
- A new service command definition in the Stratix10 service layer to
initiate the ATF version query.
- A corresponding macro definition in the header file to expose the command
ID for use by other components.

The service layer uses a Secure Monitor Call (SMC) to communicate with the
ATF and retrieve the version string, which can then be logged or validated
by client application.

Subject: [PATCH 3086/5214] ntfs: validate resident attribute lists and harden
 the validator

A base inode's $ATTRIBUTE_LIST is sanity-checked by load_attribute_list()
only on the non-resident path; ntfs_read_locked_inode() copies a *resident*
attribute list into ni->attr_list with a plain memcpy() and no validation
at all. Every subsequent walk of ni->attr_list --
ntfs_external_attr_find(), ntfs_inode_attach_all_extents() and
ntfs_attrlist_need() -- then trusts the entries are well-formed and reads
attr_list_entry fixed-header fields
(lowest_vcn at offset 8, mft_reference at offset 16, and the name) with
bounds that assume validation already happened. A crafted resident
attribute list therefore reaches those walks unvalidated and can drive
out-of-bounds reads of the attribute-list buffer.

load_attribute_list() itself reads ale->name_offset (offset 7),
ale->mft_reference (offset 16) and the name length under only an
"al < al_start + size" bound, so its own validation loop can over-read the
fixed header of a truncated trailing entry by a few bytes.

Factor the per-entry validation into ntfs_attr_list_entry_is_valid(),
which requires each entry's fixed header (offsetof(struct
attr_list_entry, name)) to be in range before any field is dereferenced,
that ale->length is a multiple of 8 covering the fixed header plus the
name, and that the entry is in use and carries a live MFT reference.
ntfs_attr_list_is_valid() walks the buffer with it and checks the entries
tile it exactly. Use the list validator in load_attribute_list()
(replacing the open-coded loop, closing its own over-read) and on the
resident path in ntfs_read_locked_inode() (which previously skipped
validation entirely); patches 2/3 reuse the per-entry helper at the other
two attribute-list walks.

Subject: [PATCH 3087/5214] ntfs: bound the look-ahead attribute-list entry in
 ntfs_external_attr_find()

When resolving an attribute lookup with a non-zero @lowest_vcn,
ntfs_external_attr_find() peeks at the next $ATTRIBUTE_LIST entry to
decide whether to keep searching, but bounds that not-yet-validated
entry only with "(u8 *)next_al_entry + 6 < al_end" (which proves just
bytes 0..6 are in range) and "(u8 *)next_al_entry + length <= al_end"
with an attacker-controlled, non-8-aligned length. It then reads
next_al_entry->lowest_vcn (an __le64 at offset 8) and the name at
next_al_entry->name_offset, both of which can lie past al_end -- the
exact end of the kvmalloc'd attribute-list buffer (allocated at the
on-disk attr_list_size, no rounding). A crafted on-disk $ATTRIBUTE_LIST
whose last entry sits a few bytes before al_end therefore yields a slab
out-of-bounds read when the inode is read.

Validate the look-ahead entry with ntfs_attr_list_entry_is_valid() (added
in patch 1/3) before dereferencing lowest_vcn and the name, so the same
fixed-header, length and name bounds the main attribute-list walk uses now
guard this read too.

Subject: [PATCH 3088/5214] ntfs: bound the attribute-list entry in
 ntfs_read_inode_mount()

The $MFT attribute-list walk in ntfs_read_inode_mount() validates each
entry only with "(u8 *)al_entry + 6 > al_end" and
"(u8 *)al_entry + le16_to_cpu(al_entry->length) > al_end", but then reads
al_entry->lowest_vcn (an __le64 at offset 8) and al_entry->mft_reference
(offset 16) -- fields beyond the 6 bytes proven in range. al_entry->length
is attacker-controlled and only required non-zero, so a short entry (e.g.
length 8) placed at the tail passes both checks while the lowest_vcn /
mft_reference reads fall past al_end.

al_end is ni->attr_list + attr_list_size (the on-disk size); the buffer is
kvzalloc(round_up(attr_list_size, SECTOR_SIZE)), so the sector rounding
usually absorbs the over-read -- but when attr_list_size is a multiple of
SECTOR_SIZE there is no slack and a crafted $MFT attribute list produces an
out-of-bounds read at mount time.

Validate the entry with ntfs_attr_list_entry_is_valid() (added in patch
1/3) before dereferencing it, matching the bound the other attribute-list
walks now use. The validator already requires the length to cover the fixed
header, which makes the separate "!al_entry->length" check redundant, so
drop it too.

Subject: [PATCH 3089/5214] ntfs: fix u16 truncation of restart-area length
 check

ntfs_check_restart_area() validates that the $LogFile restart area and
its trailing log client record array fit within the system page size:

        u16 ra_ofs, ra_len, ca_ofs;
        ...
        ra_len = ca_ofs + le16_to_cpu(ra->log_clients) *
                        sizeof(struct log_client_record);
        if (ra_ofs + ra_len > le32_to_cpu(rp->system_page_size) || ...)
                return false;

ra_len is u16, but the right-hand side is computed in size_t
(sizeof(struct log_client_record) == 160). Both ca_ofs and log_clients
come straight from the on-disk restart area. With an on-disk
log_clients of 410 the product 410 * 160 = 65600; adding ca_ofs and
storing into the u16 ra_len truncates modulo 65536 (e.g. ca_ofs 64
gives ra_len 128), so the "fits in the page" check passes even though
the client array described by log_clients extends far beyond the page.

ntfs_check_log_client_array() then walks the array bounded only by the
on-disk log_clients count:

        cr = ca + idx;
        if (cr->prev_client != LOGFILE_NO_CLIENT) ...

For log_clients 410 it dereferences records up to ca + 409 * 160,
~64 KiB past the kvzalloc(system_page_size) restart-page buffer -- an
out-of-bounds read of attacker-controlled extent, reachable when a
crafted NTFS image is mounted (load_and_check_logfile() at mount time).
This is the in-kernel analogue of CVE-2022-30789, fixed in the ntfs-3g
userspace driver but never in this revived classic driver.

Compute the restart-area length in a u32 so the existing bounds check
rejects an over-large client array instead of being defeated by the
truncation. Widen ra_ofs and ca_ofs to u32 as well: both are loaded
from __le16 on-disk fields and every comparison already promotes to
int/size_t, so this changes no result and keeps the declaration uniform.

Subject: [PATCH 3091/5214] clk: qcom: regmap-phy-mux: Rework the
 implementation

The sole reason this hw exists is to let the branch clock downstream of
it keep running, with the PHY disengaged. This is not possible with the
current implementation, as the enabled status is hijacked to mean
"enabled" = "use fast/PHY source" and "disabled" = "use XO source".

This is an issue, since the mux enable state follows that of the child
branch, making the desired "child enabled, MUX @ XO" combination
impossible.

Solve that by implementing ratesetting. Because PHY clock rates may
change at runtime and aren't really deterministic from Linux, assume
ULONG_MAX as "fast clock" and 19.2 MHz as XO. All the branches in
question already set CLK_SET_RATE_PARENT, so everything works out.

Subject: [PATCH 3092/5214] nfs: store the full NFS fileid in inode->i_ino

Now that inode->i_ino is a 64-bit value, store the full NFS fileid in
it directly instead of an XOR-folded hash. This makes NFS_FILEID() and
set_nfs_fileid() operate on inode->i_ino rather than the separate
nfsi->fileid field.

Since iget5_locked() and ilookup5() now accept a u64 hashval, pass the
full fileid as the hash parameter directly.

Convert direct nfsi->fileid accesses in nfs_check_inode_attributes(),
nfs_update_inode(), and nfs_same_file() to use inode->i_ino.

Subject: [PATCH 3093/5214] nfs: remove nfs_compat_user_ino64() and deprecate
 enable_ino64

Now that inode->i_ino stores the full 64-bit NFS fileid, the
nfs_compat_user_ino64() function is no longer needed.
generic_fillattr() already copies inode->i_ino into stat->ino, so the
explicit override in nfs_getattr() is also redundant.

Also remove the now-unused nfs_fileid_to_ino_t() and
nfs_fattr_to_ino_t() helper functions that were used to XOR-fold
64-bit fileids into the old unsigned long i_ino.

Keep the enable_ino64 module parameter as a deprecated stub that
accepts but ignores the value, logging a notice when set. This avoids
breaking existing configurations that pass nfs.enable_ino64 on the
kernel command line or in modprobe.d.

Remove the NFS_FILEID() and set_nfs_fileid() helper functions from

Also fix two pre-existing truncation bugs in nfs4trace.h where fileid
trace fields were declared as u32 instead of u64.

Subject: [PATCH 3095/5214] nfs: remove fileid field from struct nfs_inode

Now that all NFS client code uses inode->i_ino directly to store and
access the 64-bit NFS fileid, the separate fileid field in struct
nfs_inode is unused. Remove it to save 8 bytes per NFS inode.

Subject: [PATCH 3096/5214] sunrpc: Fix error handling in
 rpc_sysfs_xprt_switch_add_xprt_store()

xprt_create_transport() never returns NULL, only valid pointers or
error pointers. Using IS_ERR_OR_NULL() is incorrect, and PTR_ERR(NULL)
would return 0, which indicates EOF in a sysfs store function.

Fix this by using IS_ERR() instead of IS_ERR_OR_NULL().

Fixes: df210d9b0951 ("sunrpc: Add a sysfs file for adding a new xprt")

Subject: [PATCH 3097/5214] NFSv4/flexfiles: reject zero filehandle version
 count

ff_layout_alloc_lseg() decodes the filehandle-version array count
from the flexfiles layout body. The value is used as the count for
kzalloc_objs(), and the current code only rejects NULL.

A zero count yields ZERO_SIZE_PTR, which can be stored in
dss_info->fh_versions even though later flexfiles paths assume that at
least one filehandle version exists.

Reject fh_count == 0 before the allocation, matching the existing zero
version_count validation in the flexfiles GETDEVICEINFO parser.

A QEMU/KASAN run with a malformed flexfiles layout hit:

  KASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017]
  RIP: 0010:ff_layout_encode_ff_layoutupdate.isra.0+0x15f/0x750
  ff_layout_encode_layoutreturn+0x683/0x970
  nfs4_xdr_enc_layoutreturn+0x278/0x3a0
  Kernel panic - not syncing: Fatal exception

The patched kernel rejects the malformed layout without KASAN/oops/panic,
and a valid fh_count=1 regression still opens, reads, and unmounts cleanly.

Subject: [PATCH 3098/5214] NFSv4: clear exception state on successful mkdir
 retry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After a server returns NFS4ERR_DELAY for an NFSv4 CREATE issued by
mkdir(2), the client correctly waits and retries.  When the retry
succeeds, however, mkdir(2) can still surface -EEXIST to userspace
even though the directory was just created on the server.

Reproducer (random 16-hex names so collisions are not the cause)
against an in-kernel Linux nfsd; reproduces under both NFSv4.0 and
NFSv4.2:

  N=2000000; base=/var/gdc/export
  for ((i=1; i<=N; i++)); do
      d=$base/$(openssl rand -hex 8)
      mkdir "$d" 2>/dev/null || echo "$(date +%T) failed loop=$i $d"
      rmdir "$d" 2>/dev/null
  done

Failures cluster at the cadence at which the server-side auth/export
cache refresh path causes nfsd to return NFS4ERR_DELAY for CREATE.

A wire trace of one failure (the three CREATE RPCs all come from a
single mkdir(2), generated by the do-while in nfs4_proc_mkdir()):

  client -> server  CREATE name=...  -> NFS4ERR_DELAY
  ~100 ms later
  client -> server  CREATE name=...  -> NFS4_OK         (dir created)
  ~80 us later
  client -> server  CREATE name=...  -> NFS4ERR_EXIST   (correct)

Since commit dd862da61e91 ("nfs: fix incorrect handling of large-number
NFS errors in nfs4_do_mkdir()"), nfs4_handle_exception() is called only
when _nfs4_proc_mkdir() returned an error.  That gate breaks retry-state
hygiene: nfs4_do_handle_exception() resets exception.{delay,recovering,
retry} to 0 on entry, so calling it on success is what previously
cleared the retry flag set by the preceding NFS4ERR_DELAY iteration.
With the gate in place, exception.retry stays at 1 after the successful
retry, the loop runs once more, and the resulting CREATE for an
already-created name yields NFS4ERR_EXIST -> -EEXIST to userspace.

Drop the conditional and call nfs4_handle_exception() unconditionally,
matching every other do-while in fs/nfs/nfs4proc.c (nfs4_proc_symlink(),
nfs4_proc_link(), etc.).  The dentry/status separation introduced by
that commit is preserved.

Subject: [PATCH 3099/5214] xprtrdma: Move long delayed work on
 system_dfl_long_wq
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the code enqueue work items using {queue|mod}_delayed_work(),
using system_long_wq. This workqueue should be used when long works are
expected and it is a per-cpu workqueue.

The function(s) end up calling __queue_delayed_work(), which set a global
timer that could fire anywhere, enqueuing the work where the timer fired.

Unbound works could benefit from scheduler task placement, to optimize
performance and power consumption. Long work shouldn't stick to a single
CPU.

Recently, a new unbound workqueue specific for long running work has
been added:

    c116737e972e ("workqueue: Add system_dfl_long_wq for long unbound works")

Since the workqueue work doesn't rely on per-cpu variables, there is no
obvious reason that justify the use of a per-cpu workqueue. So change
system_long_wq with system_dfl_long_wq so that the work may benefit from
scheduler task placement.

A layout can still be striped with num_fh = 1 as it is perfectly possible

We should not be called with flseg->dsaddr = NULL, but if for some reason
we do, return our best guess with is flseg->num_fh > 1.

Subject: [PATCH 3102/5214] NFS: fix eof updates after NFSv4.2
 fallocate/zero-range

Generic/075 reliably exposes a regression when the client holds an
NFSv4 write delegation: ZERO_RANGE/ALLOCATE extends the file on the
server, but the local inode keeps the old i_size. The test then fails
with 'Size error' because the post-op attribute refresh refuses to
touch i_size while a delegation is outstanding, and the cached EOF
was never marked stale.

Update _nfs42_proc_fallocate() so that on success it:

- bumps i_size when the operation extends the file, and
- marks NFS_INO_INVALID_BLOCKS since the block count can also change

Tested with xfstests generic/075 over NFSv4.2.

pnfs_put_layout_hdr(lo) is called before trace_pnfs_update_layout(),

tracepoint accesses lo's fields.

Fix this by moving the tracepoint call before pnfs_put_layout_hdr(lo).

Subject: [PATCH 3104/5214] xprtrdma: Use sendctx DMA state for Send signaling

Send signaling matters only when the prepared Send has page
mappings to unmap. Today that test is expressed indirectly with
rl_kref, because the Send-side reference is taken only for Sends
with mapped SGEs.

Split the SGE DMA unmap loop into its own helper and use
sc_unmap_count directly for the signaling decision. This keeps the
current behavior but removes one dependency on the old rl_kref
semantics before the request lifetime rules are changed.

Subject: [PATCH 3105/5214] xprtrdma: Decouple req recycling from RPC
 completion

rl_kref formerly served two distinct lifetimes through a single
refcount: it gated when a Reply could wake its RPC task, and it
gated when an rpcrdma_req could return to its free pool. The
marshal path took the Send-side reference only when SGEs needed
DMA-unmap (sc_unmap_count > 0), which made a Send carrying only
pre-registered buffers an exception: the Reply handler dropped
rl_kref from 1 to 0 and freed the req while the HCA might still
be DMA-reading from its send buffer.

Give rl_kref a narrower job. The RPC layer takes one reference
when slot allocation hands a req out. rpcrdma_prepare_send_sges()
takes a Send-side reference unconditionally after WR preparation
succeeds. xprt_rdma_free_slot() and xprt_rdma_bc_free_rqst() drop
the RPC-layer reference; rpcrdma_sendctx_unmap() drops the
Send-side reference. The req returns to its free pool only after
both owners have signed off.

The existing kref_init(&req->rl_kref) call in
rpcrdma_prepare_send_sges() is removed. Initialization moves to
the slot-allocation paths (xprt_rdma_alloc_slot and
rpcrdma_bc_rqst_get), and the release callback re-arms rl_kref
before the req returns to a free pool. A re-init in the marshal
path would discard the RPC-layer reference that already exists
on entry.

Three invariants follow:

  - Any rpcrdma_req held by an rpc_rqst has rl_kref >= 1.
    xprt_rdma_alloc_slot(), rpcrdma_bc_rqst_get(), and the
    backlog-wake branch in xprt_rdma_alloc_slot() each kref_init
    rl_kref before publishing the req. Without this invariant,
    an RPC task that aborts between slot allocation and marshal
    (gss_refresh failure or signal during call_connect, for
    example) would drive xprt_release() ->
    xprt_rdma_free_slot() -> kref_put against a refcount of
    zero, saturating refcount_t and stranding the slot.

  - The Send-side reference is taken only after WR prep
    succeeds. A mapping failure in rpcrdma_prepare_send_sges()
    runs rpcrdma_sendctx_cancel(), which DMA-unmaps the sendctx
    and clears sc_req without touching rl_kref. The sendctx
    ring walks in rpcrdma_sendctx_put_locked() and
    rpcrdma_sendctxs_destroy() skip entries with sc_req == NULL,
    so a burst of -EIO marshal failures cannot hold reqs off
    rb_send_bufs.

  - The release callback re-arms rl_kref so the next consumer
    enters with the invariant satisfied.

Replies now complete the RPC directly. rpcrdma_reply_handler()
calls rpcrdma_complete_rqst() in place of kref_put on the
non-LocalInv branch. The LocalInv branch already completes the
RPC from frwr_unmap_async() and is unaffected.

Because Send-side references can now outlive RPC completion,
connection teardown drains sendctx entries whose unsignaled
Sends never had a later signaled completion to walk the ring.
rpcrdma_sendctxs_destroy() walks the active range and runs
rpcrdma_sendctx_unmap() on each entry with a non-NULL sc_req
before the request buffers are reset, and is moved ahead of
rpcrdma_reqs_reset() in rpcrdma_xprt_disconnect() so the reqs
are still in their pre-reset state when the Send-side refs are
released.

The drain creates a teardown-ordering hazard on the backchannel
path. With the new lifetime, releasing a bc_prealloc req from
rpcrdma_req_release() re-adds it to bc_pa_list. The disconnect
in xprt_rdma_destroy() runs after xprt_destroy_backchannel() has
already emptied bc_pa_list, so the drained reqs would otherwise
leak. xprt_rdma_destroy() now runs xprt_rdma_bc_destroy(xprt, 0)

Subject: [PATCH 3106/5214] xprtrdma: Add request-pool slack for delayed
 recycling

After the previous patch gates req recycling on Send completion,
a completed RPC's rpcrdma_req can remain pinned by the sendctx
ring until the next signaled Send completion releases it. The
transmitted-RPC ceiling is unchanged: xprt_request_get_cong()
gates Sends against xprt->cwnd, the RPC/RDMA credit window fed
by server-granted credits and capped at re_max_requests. The
req pool, however, must exceed max_reqs by enough that this
recycle delay does not stall a slot allocation that the credit
window would admit.

The headroom is bounded. frwr_open() sets re_send_batch to
re_max_requests >> 3 -- one in every eight Sends is signaled --
so at most re_send_batch unsignaled Sends can be outstanding
before the next signaled completion releases them. That equals
max_reqs / 8 reqs in the worst case, with a one-slot floor for
small max_reqs values where the right-shift rounds to zero.

The sendctx ring and the hardware Send Queue are not enlarged
to match. Both are sized in rpcrdma_sendctxs_create() and
frwr_query_device() for re_max_requests in-flight Sends, which
is the ceiling the credit window enforces. The pool slack does
not raise that ceiling -- it only lets allocation keep pace
with the credit window during the brief interval in which
earlier reqs are pinned waiting for the next signaled
completion. At any moment, at most re_send_batch sendctxes are
held by unswept unsignaled Sends, leaving the rest of the ring
available for newly admitted Sends.

Allocate max_reqs + DIV_ROUND_UP(max_reqs, 8) request objects
and name the slack calculation at the allocation site so the
1/8 bound stays tied to the Send-signaling batch size.

Subject: [PATCH 3107/5214] xprtrdma: Clear receive-side ownership pointers on
 release

Three small ownership-state cleanups land the transport in a
state that lets future reviewers reason about each pointer
locally rather than tracing the whole reply path:

rpcrdma_rep_put() clears rep->rr_rqst before the rep enters
rb_free_reps so that no rep on the free list still carries a
stale rqst pointer.  rpcrdma_reply_handler() and
rpcrdma_unpin_rqst() are the only sites that set rr_rqst;
rpcrdma_reply_handler() hands the rep through
rpcrdma_rep_put(), and rpcrdma_unpin_rqst() NULLs rr_rqst
directly because its error path abandons the rep for
teardown cleanup rather than returning it to rb_free_reps.

rpcrdma_reply_put() NULLs req->rl_reply before calling
rpcrdma_rep_put().  The previous order placed the rep on
rb_free_reps while req->rl_reply still pointed at it; the
window was harmless because xprt_rdma_free_slot() holds the
req exclusively across the pair, but closing it makes the
invariant 'rep on rb_free_reps implies no req references it'
strictly checkable.

rpcrdma_sendctx_unmap() and rpcrdma_sendctx_cancel() clear
req->rl_sendctx after dropping the sendctx pointer in the
sendctx ring.  Without this, req->rl_sendctx survives across
Send completion and points at a sendctx that may already have
been reassigned by rpcrdma_sendctx_get_locked() to a different
req.  No caller dereferences the stale pointer today --
rpcrdma_prepare_send_sges() overwrites it before the next
Send -- but a NULL is a more honest representation of 'the
Send is no longer outstanding' and lets the assertion patch
that follows trip on any future regression.

Subject: [PATCH 3108/5214] xprtrdma: Document and assert reply-handler
 invariants

The xprtrdma reply path has been the subject of recurring
LLM-driven review claims that 'an RPC can complete while
receive buffers are still DMA-mapped' or that 'the req can be
freed while the HCA still owns the send buffer.'  No runtime
reproducer has surfaced, but the absence of a written-down
invariant set lets each pass of automated review reach the
same hypothetical conclusion.  Subsequent fixes against
ce2f9a4d9ccc ('xprtrdma: Decouple req recycling from RPC
completion') closed the underlying races but did not document
the closure where future readers will look for it.

State the invariants explicitly in a comment above
rpcrdma_reply_handler() and back four of them with
WARN_ON_ONCE() probes positioned where each invariant is
locally checkable on the previous patch's cleaned-up
ownership state:

- I1 (Receive WR ownership): WARN at rpcrdma_post_recvs() that
  a rep pulled from rb_free_reps carries rr_rqst == NULL.

- I2 (rep attachment): WARN at rpcrdma_reply_put() that
  req->rl_reply was NULLed before the matching rep_put.

- I3 (Registered-MR fence): WARN at rpcrdma_complete_rqst()
  that req->rl_registered is empty.  Strong send-queue
  ordering of the LocalInv WR chain makes the last
  completion observe the ib_dma_unmap_sg() of every earlier
  MR, so 'list empty' implies 'all MRs unmapped'.

- I4 (Send-buffer release): WARN at rpcrdma_req_release()
  that req->rl_sendctx is NULL.  Reaching the kref release
  callback requires both the RPC-layer and Send-side
  references to have dropped; the Send-side drop runs in
  rpcrdma_sendctx_unmap(), which clears rl_sendctx
  (previous patch).  A non-NULL rl_sendctx here would mean
  the Send-side owner had not run -- a contradiction.

The XXX comment in xprt_rdma_free() about signal-driven
release racing the Send completion described the pre-decouple
state.  Replace it with a one-line note pointing at the
invariant set, since the kref scheme now holds the req across
the in-flight Send regardless of which path released the
rpc_task.

I5 (req lifecycle) is stated in the comment but not probed:
making it locally assertible would require moving kref_init
out of rpcrdma_req_release(), which in turn requires adding
kref_init to the bc_pa_list and backlog-wake reuse paths.
That restructuring is deferred -- the invariant is unchanged
either way.

frwr_unmap_sync() and frwr_unmap_async() drain rl_registered via

Reword the comment to match what the assertion actually checks.

The warning occurs because the block layout driver unregisters the SCSI
device while the inode lock is still held. Device unregistration issues
a SCSI PR command, which may sleep, resulting in a "scheduling while
atomic" warning.

During layout return, ext_tree_remove() invokes the layout driver's
return_range callback while holding the inode lock. For block layouts,
this callback eventually calls bl_unregister_scsi(), which may block in
scsi_execute_cmd() while issuing PR commands to the device.

Fix this by deferring the return_range callbacks until after the inode
lock has been released. The layout header reference count is incremented
before invoking return_range(), ensuring that the layout header remains
valid while the layout driver removes extents from the extent tree.

Subject: [PATCH 3112/5214] ima: Remove ima_h_table structure

The ima_h_table structure is a collection of IMA measurement list
metadata - number of records in the IMA measurement list, number of
integrity violations, and a hash table containing the IMA template data
hash, needed to prevent measurement list record duplication.

Removing records from the measurement list needs to be reflected in the
hash table. As a pre-req to removing records from the measurement list,
separate those counters from the hash table, remove the ima_h_table
structure, and just replace the hash table pointer.

Finally, rename ima_show_htable_value(), ima_show_htable_violations()
and ima_htable_violations_ops respectively to ima_show_counter(),
ima_show_num_violations() and ima_num_violations_ops.

Subject: [PATCH 3113/5214] ima: Replace static htable queue with dynamically
 allocated array

The IMA hash table is a fixed-size array of hlist_head buckets:

    struct hlist_head ima_htable[IMA_MEASURE_HTABLE_SIZE];

IMA_MEASURE_HTABLE_SIZE is (1 << IMA_HASH_BITS) = 1024 buckets, each a
struct hlist_head (one pointer, 8 bytes on 64-bit). That is 8 KiB allocated
in BSS for every kernel, regardless of whether IMA is ever used, and
regardless of how many measurements are actually made.

Replace the fixed-size array with a RCU-protected pointer to a dynamically
allocated array that is initialized in ima_init_htable(), which is called
from ima_init() during early boot. ima_init_htable() calls the static
function ima_alloc_replace_htable() which, other than initializing the hash
table the first time, can also hot-swap the existing hash table with a
blank one.

The allocation in ima_alloc_replace_htable() uses kcalloc() so the buckets
are zero-initialised (equivalent to HLIST_HEAD_INIT { .first = NULL }).
Callers of ima_alloc_replace_htable() must call synchronize_rcu() and free
the returned hash table.

Finally, access the hash table with rcu_dereference() in
ima_lookup_digest_entry() (reader side) and with
rcu_dereference_protected() in ima_add_digest_entry() (writer side).

No functional change: bucket count, hash function, and all locking remain
identical.

Subject: [PATCH 3115/5214] ima: Introduce per binary measurements list type
 binary_runtime_size value

Make binary_runtime_size as an array, to have separate counters per binary
measurements list type. Currently, define the BINARY type for the existing
binary measurements list.

Introduce ima_update_binary_runtime_size() to facilitate updating a
binary_runtime_size value with a given binary measurement list type.

Also add the binary measurements list type parameter to
ima_get_binary_runtime_size(), to retrieve the desired value. Retrieving
the value is now done under the ima_extend_list_mutex, since there can be
concurrent updates.

No functional change (except for the mutex usage, that fixes the
concurrency issue): the BINARY array element is equivalent to the old
binary_runtime_size.

Introduce _ima_measurements_start() and _ima_measurements_next(), renamed
from ima_measurements_start() and ima_measurements_next(), to include the
list head as an additional parameter, so that iteration on different lists
can be implemented by calling those functions.

No functional change: ima_measurements_start() and ima_measurements_next()
pass the ima_measurements list head, used before. They become wrappers for
the new functions.

Subject: [PATCH 3117/5214] ima: Mediate open/release method of the
 measurements list

Introduce the ima_measure_users counter, to implement a semaphore-like
locking scheme where the binary and ASCII measurements list interfaces can
be concurrently opened by multiple readers, or alternatively by a single
writer. In addition, allow the same writer to open the other interfaces for
write or read/write, so that it can see the same measurement state across
all the interfaces.

A semaphore cannot be used because the kernel cannot return to user space
with a lock held.

Introduce the ima_measure_lock() and ima_measure_unlock() primitives, to
respectively lock/unlock the interfaces (safely with the ima_measure_users
counter, without holding a lock).

Finally, introduce _ima_measurements_open() to lock the interface before
seq_open(), and call it from ima_measurements_open() and
ima_ascii_measurements_open(). And, introduce ima_measurements_release(),
to unlock the interface.

Require CAP_SYS_ADMIN if the interface is opened for write (not possible
for the current measurements interfaces, since they only have read
permission).

No functional changes: multiple readers are allowed as before.

Subject: [PATCH 3120/5214] ima: Add support for staging measurements with
 prompt

Introduce the ability of staging the IMA measurement list and deleting them
with a prompt.

Staging means moving the current measurement list records to a separate
location, and allowing users to read and delete it. This causes the current
measurement list to be emptied (since records were moved) and new
measurements to be added on the empty list. Staging can be done only once
at a time. In the event of kexec(), staging is aborted and staged records
will be carried over to the new kernel.

Introduce ascii_runtime_measurements_<algo>_staged and
binary_runtime_measurements_<algo>_staged interfaces to access and delete
the measurements.

Use 'echo A > <IMA _staged interface>' and
'echo D > <IMA _staged interface>' to respectively stage and delete the
entire measurements list. Locking of these interfaces is also mediated with
a call to _ima_measurements_open() and with ima_measurements_release().

Implement the staging functionality by introducing the new global
measurements list ima_measurements_staged, and ima_queue_stage() and
ima_queue_staged_delete_all() to respectively move measurements from the
current measurements list to the staged one, and to move staged
measurements to the ima_measurements_trim list for deletion. Introduce
ima_queue_delete() to delete the measurements.

Staging is forbidden after measurement is suspended, and between staging
and deleting, so that walking the staged and current measurements list can
be done locklessly in ima_dump_measurement_list(). Strict ordering of
suspending and dumping is enforced by two reboot notifiers with different
priority. Refusing to delete staged measurements also signals to user space
that those measurements are already carried over to the secondary kernel,
so that it does not save them twice.

Finally, introduce the BINARY_STAGED and BINARY_FULL binary measurements
list types, to maintain the counters and the binary size of staged
measurements and the full measurements list (including records that were
staged). BINARY still represents the current binary measurements list.

Use the binary size for the BINARY + BINARY_STAGED types in
ima_add_kexec_buffer(), since both measurements list types are copied to
the secondary kernel during kexec. Use BINARY_FULL in
ima_measure_kexec_event(), to generate a critical data record.

It should be noted that the BINARY_FULL counter is not passed through
kexec. Thus, the number of records included in the kexec critical data
records refers to the records since the critical data records generated
from the previous kexec event.

Note: This code derives from the Alt-IMA Huawei project, whose license is
      GPL-2.0 OR MIT.

Subject: [PATCH 3121/5214] ima: Add support for flushing the hash table when
 staging measurements

During staging and delete, measurements are not completely deallocated.
Their entry digest portion is kept and is still reachable with the hash
table to detect duplicate records. If the number of records is significant,
this reduces the memory saving benefit of staging.

Some users might be interested in achieving the best memory saving (the
measurements are completely deallocated) at the cost of having duplicate
records across the staged measurement lists. Duplicate records are still
avoided within the current measurement list.

Introduce the new kernel option ima_flush_htable to decide whether or not
the digests of staged measurement records are flushed from the hash table,
when they are deleted, to achieve the maximum memory saving.

When the option is enabled, replace the old hash table with a new one,
by calling ima_alloc_replace_htable(), and completely delete the
measurements records.

Note: This code derives from the Alt-IMA Huawei project, whose license is
      GPL-2.0 OR MIT.

Subject: [PATCH 3122/5214] ima: Support staging and deleting N measurements
 records

Add support for sending a value N between 1 and ULONG_MAX to the IMA
original measurement interface. This value represents the number of
measurements that should be deleted from the current measurements list. In
this case, measurements are staged in an internal non-user visible list,
and immediately deleted.

This staging method allows the remote attestation agents to easily separate
the measurements that were verified (staged and deleted) from those that
weren't due to the race between taking a TPM quote and reading the
measurements list.

In order to minimize the locking time of ima_extend_list_mutex, deleting
N records is realized by doing a lockless walk in the current measurements
list to determine the N-th entry to cut, to cut the current measurements
list under the lock, and by deleting the excess records after releasing the
lock.

Flushing the hash table is not supported for N records, since it would
require removing the N records one by one from the hash table under the
ima_extend_list_mutex lock, which would increase the locking time.

+==================================
+IMA Measurements Export and Delete
+==================================
+
+
+Introduction
+============
+
+The IMA measurements list is currently stored in the kernel memory. Memory
+occupation grows linearly with the number of records, and can become a
+problem especially in environments with reduced resources.
+
+While there is an advantage in keeping the IMA measurements list in kernel
+memory, so that it is always available for reading from the securityfs
+interfaces, storing it elsewhere would make it possible to free precious
+memory for other kernel usage.
+
+The IMA measurements list needs to be retained and safely stored for new
+attestation servers to validate it. Assuming the IMA measurements list is
+properly saved, storing it outside the kernel does not introduce security
+issues, since its integrity is anyway protected by the TPM.
+
+Hence, the new IMA staging mechanism is introduced to export IMA
+measurements to user space and delete them from kernel space.
+
+Staging consists in atomically moving the current measurements list to a
+temporary list, so that measurements can be deleted afterwards. The staging
+operation locks the hot path (racing with addition of new measurements) for
+a very short time, only for swapping the list pointers. Deletion of the
+measurements instead is done locklessly, away from the hot path.
+
+There are two flavors of the staging mechanism. In the staging with prompt,
+all current measurements are staged, read and deleted upon confirmation. In
+the staging and deleting flavor, N measurements are staged from the
+beginning of the current measurements list and immediately deleted without
+confirmation.
+
+
+Management of Staged Measurements
+=================================
+
+Since with the staging mechanism measurement records are removed from the
+kernel, the staged measurements need to be saved in a storage and
+concatenated together, so that they can be presented during remote
+attestation as if staging was never done. This task can be accomplished by
+a remote attestation agent modified to support staging, or a system
+service.
+
+Coordination is necessary in the case where there are multiple actors
+requesting measurements to be staged.
+
+In the staging with prompt case, the measurement interfaces can be accessed
+only by one actor (writer) at a time, so the others will get an error until
+the former closes it. Since the actors don't care about N, when they gain
+access to the interface, they will get all the staged measurements at the
+time of their request.
+
+In the case of staging and deleting, coordination is more important, since
+there is the risk that two actors unaware of each other compute the value N
+on the current measurements list and request IMA to stage N twice.
+
+
+Remote Attestation Agent Workflow
+=================================
+
+Remote attestation agents can be configured to always present all the
+measurements to the remote verifiers or, alternatively, to only provide the
+measurements that have not been verified yet by the remote verifiers.
+
+In the latter case, determining which measurements need to be sent and
+verified must solely depend on the remote verifier. The remote attestation
+agent can proactively send partial measurements, at the condition that they
+are the ones that the remote verifier needs.
+
+An agent can rely on one of the supported staging methods to proactively
+send to a remote verifier the measurements since the previous request up
+to the ones that verify the TPM quote obtained in the current request.
+The workflow with each staging method is the following.
+
+With staging with prompt, the agent stages the current measurements list,
+reads and stores the measurements in a storage and immediately requests
+IMA to delete the staged measurements from kernel memory. Afterwards, it
+calculates N by replaying the PCR extend on the stored measurements until
+the calculated PCRs match the quoted PCRs. It then keeps the measurements
+in excess for the next attestation request.
+
+At the next attestation request, the agent performs the same steps above,
+and concatenates the new measurements to the ones in excess from the
+previous request. Also in this case, the agent replays the PCR extend until
+it matches the currently quoted PCRs, keeps the measurements in excess and
+presents the new N measurement records to the remote attestation server.
+
+With the staging and deleting method, the agent reads the current
+measurements list, calculates N and requests IMA to delete only those. The
+measurements in excess are kept in the IMA measurements list and can be
+retrieved at the next remote attestation request.
+
+While keeping only the excess measurements in the storage could be
+sufficient to serve the requests of a remote verifier, it is advised to
+keep all the obtained measurements locally, as they might be needed for the
+attestation with a different remote verifier.
+
+
+Usage
+=====
+
+The IMA staging mechanism can be enabled from the kernel configuration with
+the CONFIG_IMA_STAGING option. This option prevents inadvertently removing
+the IMA measurement list on systems which do not properly save it.
+
+If the option is enabled, IMA duplicates the current securityfs
+measurements interfaces (both binary and ASCII), by adding the ``_staged``
+file suffix. Both the original and the staging interfaces gain the write
+permission for the root user and group, but require the process to have
+CAP_SYS_ADMIN set.
+
+The staging mechanism supports two flavors.
+
+
+Staging with prompt
+~~~~~~~~~~~~~~~~~~~
+
+The current measurements list is moved to a temporary staging area,
+allowing it to be saved to external storage, before being deleted upon
+confirmation.
+
+This staging process is achieved with the following steps.
+
+ 1. ``echo A > <_staged interface>``: the user requests IMA to stage the
+    entire measurements list;
+ 2. ``cat <_staged interface>``: the user reads the staged measurements;
+ 3. ``echo D > <_staged interface>``: the user requests IMA to delete
+    staged measurements.
+
+
+Staging and deleting
+~~~~~~~~~~~~~~~~~~~~
+
+N measurements are staged to a temporary staging area, and immediately
+deleted without further confirmation.
+
+This staging process is achieved with the following steps.
+
+ 1. ``cat <original interface>``: the user reads the current measurements
+    list and determines what the value N for staging should be;
+ 2. ``echo N > <original interface>``: the user requests IMA to delete N
+    measurements from the current measurements list.
+
+
+Interface Access
+================
+
+In order to avoid the IMA measurements list being suddenly truncated by the
+staging mechanism during a read, or having multiple concurrent staging, a
+semaphore-like locking scheme has been implemented on all the measurements
+list interfaces.
+
+Multiple readers can access concurrently the original and staged
+interfaces, and they can be in mutual exclusion with one writer. In order
+to see the same state across all the measurement interfaces, the same
+writer is allowed to open multiple interfaces for write or read/write.
+
+If an illegal access occurs, the open to the measurements list interface is
+denied.
+
+
+Kexec
+=====
+
+In the event a kexec() system call occurs between staging and deleting, the
+staged measurement records are marshalled before the current measurements
+list, so that they are both available when the secondary kernel starts.
+
+If measurement is suspended before requesting to delete staged or current
+measurements, IMA returns an error to user space to let it know that
+marshalling is already in progress, so that it does not save the
+measurements twice.
+
+IMA also disallows staging when suspending measurement, to avoid the
+situation where neither measurements are carried over to the secondary
+kernel, nor they are saved by user space to the storage.
+
+
+Hash table
+==========
+
+By default, the template digest of staged measurement records are kept in
+kernel memory (only template data are freed), to be able to detect
+duplicate records independently of staging.
+
+The new kernel option ``ima_flush_htable`` has been introduced to
+explicitly request a complete deletion of the staged measurements, for
+maximum kernel memory saving. If the option has been specified, duplicate
+records are still avoided on records of the current measurements list,
+but there can be duplicates between different groups of staged
+measurements.
+
+Flushing the hash table is supported only for the staging with prompt
+flavor. For the staging and deleting flavor, it would have been necessary
+to lock the hot path adding new measurements for the time needed to remove
+each selected measurement individually.

Subject: [PATCH 3124/5214] nfs: keep PG_UPTODATE clear after read errors in
 page groups

When a read request is split into multiple subrequests, earlier
completions may advance PG_UPTODATE state for the page group once
their bytes fall within hdr->good_bytes. If a later subrequest in
the same group then completes with NFS_IOHDR_ERROR, the read path
needs to clear any accumulated PG_UPTODATE state and keep later
completions from rebuilding it.

Otherwise, a subsequent successful subrequest can re-enter
nfs_page_group_set_uptodate(), restore the page-group sync state,
and leave stale PG_UPTODATE behind for nfs_page_group_destroy()
to trip over in nfs_free_request().

Add a sticky page-group read-failed flag. Once any subrequest in
the group is known to be bad, mark the group failed, clear any
accumulated PG_UPTODATE state, and refuse further PG_UPTODATE
synchronization for the rest of the completion walk.

Subject: [PATCH 3125/5214] sunrpc: fix uninitialized xprt_create_args
 structure

The xprt_create_args structure is allocated on the stack without
initialization in rpc_sysfs_xprt_switch_add_xprt_store(). While some
fields are manually populated, critical fields like srcaddr, bc_xps,
and flags contain uninitialized stack garbage.

This can lead to:
1. Kernel panic when xs_setup_xprt() dereferences garbage srcaddr
2. Information leak if srcaddr points to sensitive stack data
3. Unpredictable behavior if flags has random bits set

The fix is to zero-initialize the structure to ensure all unused
fields are NULL/0, preventing the transport setup code from acting
on garbage data.

Subject: [PATCH 3126/5214] NFSv4/flexfiles: honor FF_FLAGS_NO_IO_THRU_MDS on
 fatal DS connect errors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit f06bedfa62d5 ("pNFS/flexfiles: don't attempt pnfs on fatal DS
errors") teaches ff_layout_{read,write}_pagelist() to return
PNFS_NOT_ATTEMPTED when nfs4_ff_layout_prepare_ds() fails with a
nfs_error_is_fatal() errno (e.g. -ETIMEDOUT from a SOFTCONN connect
deadline, -ENOMEM, -ERESTARTSYS), so that the client gives up instead
of spinning.  pnfs_do_{read,write}() then dispatches the I/O through
pnfs_{read,write}_through_mds() → nfs_pageio_reset_{read,write}_mds().

That fallback is unconditional and silently violates FF_FLAGS_NO_IO_THRU_MDS:
when the layout segment carries the flag (typically single-mirror
appliance layouts where MDS I/O is explicitly forbidden), the
out_failed: path's \`&& !ds_fatal_error\` clause overrides the flag's
short-circuit through ff_layout_avoid_mds_available_ds() and routes
the I/O to the MDS file handle anyway.

This is reachable in practice during a data-server restart: SOFTCONN
exhaustion produces -ETIMEDOUT, which is fatal per nfs_error_is_fatal(),
which triggers PNFS_NOT_ATTEMPTED, which silently goes to MDS.

Preserve the upstream "don't spin on fatal errors" intent for layouts
that permit MDS fallback.  For layouts with FF_FLAGS_NO_IO_THRU_MDS
set, mark the layout for return and request PNFS_TRY_AGAIN instead;
if the server cannot supply a usable layout the failure now surfaces
cleanly via pnfs_update_layout(), rather than via silent MDS I/O that
contradicts the flag.

Subject: [PATCH 3127/5214] NFSv4/flexfiles: honor FF_FLAGS_NO_IO_THRU_MDS in
 pg_get_mirror_count_write

The FF_FLAGS_NO_IO_THRU_MDS flag lives on each lseg, so any fallback
decision made when there is no current lseg (e.g. between LAYOUTRETURN
and the next LAYOUTGET) cannot run the per-lseg check.

Introduce a sticky hdr-level ditto for FF_FLAGS_NO_IO_THRU_MDS in
struct nfs4_flexfile_layout::flags (NFS4_FF_HDR_NO_IO_THRU_MDS bit),
set whenever ff_layout_alloc_lseg() parses an lseg with the flag.  The
bit is never cleared for the lifetime of the layout hdr; the server is
assumed to be consistent in its no-fallback policy per file.
kzalloc() in ff_layout_alloc_layout_hdr() zero-initializes the field.

Use the new ff_layout_hdr_no_fallback_to_mds() helper to gate
ff_layout_pg_get_mirror_count_write(): when pnfs_update_layout() returns
NULL (e.g. NFS_LAYOUT_BULK_RECALL, pnfs_layout_io_test_failed,
pnfs_layoutgets_blocked) the existing code unconditionally calls
nfs_pageio_reset_write_mds().  This is a source of unwanted WRITE to
MDS.  Fix it by checking NFS4_FF_HDR_NO_IO_THRU_MDS bit, and if set
surface -EAGAIN instead; the writepage-side caller (nfs_do_writepage()
for buffered, nfs_direct_write_reschedule() for O_DIRECT) then
redirties the request so writeback retries via pNFS.

Handle async requests properly by using nfs_start_io_direct_nowait,
and then expose FMODE_NOWAIT since it's now supported for direct reads.

Subject: [PATCH 3130/5214] KVM: guest_memfd: fix NUMA interleave index
 double-counting

kvm_gmem_get_policy() sets the interleave index (the output param that's
typically named "ilx") to the full page offset (vm_pgoff + vma offset).
But get_vma_policy() adds the page offset on top of the interleave index,
and so the offset is counted twice.  This causes NUMA interleaving to skip
nodes: for order-0 pages the effective index jumps by 2 for each
consecutive page.

The vm_op.get_policy() implementation should return only a per-file bias in
the interleave index (like shmem_get_policy does with inode->i_ino),
letting get_vma_policy() add the page-offset component.

Fix by setting the output interleave index to the inode number (a la shmem)
instead of the full page offset, as the index is intended to be a constant,
semi-random value for a given file, e.g. so that interleaving doesn't start
at the same node for every file, and so that allocations are round-robined
across nodes based on the page offset (the selected node would bounce/skip
around if the index isn't constant).

Found by Sashiko (sashiko.dev) AI code review.

Subject: [PATCH 3131/5214] KVM: x86: hyper-v: Bound the bank index when
 querying sparse banks

When checking if a VP ID is included in a sparse bank set, explicitly check
that the ID can actually be contained in a sparse bank (the TLFS allows for
a maximum of 64 banks of 64 vCPUs each).  When handling a paravirtual TLB
flush for L2, the VP ID is copied verbatim from the enlightened VMCS,
without any bounds check, i.e. isn't guaranteed to be under the limit of
4096.

Failure to check the bounds of the VP ID leads to an out-of-bounds read
when testing the sparse bank, and super strictly speaking could lead to KVM
performing an unnecessary TLB flush for an L2 vCPU.

of FIXED_CTR_CTRL to detect changes, not the guest's original value.  For
guests with a mediated PMU, overwriting fixed_ctr_ctrl_hw at the start of
reprogramming without actually reacting to changes in fixed_ctr_ctrl_hw can
lead to KVM ignoring PMU event filters.

E.g. if the guest attempts to enable a fixed PMC that is disallowed, and
then toggles a different PMC in a subsequent WRMSR, KVM will update
pmu->fixed_ctr_ctrl_hw and reprogram the PMC that is changing, but not the
others that are now effectively enabled in pmu->fixed_ctr_ctrl_hw.

Note, the perf-based PMU is unaffected, as it doesn't use fixed_ctr_ctrl_hw
(which is also why keying off fixed_ctr_ctrl_hw works for both PMUs.

Note #2, fixed_ctr_ctrl_hw won't mess up pmc_in_use either, because the
latter isn't used by the mediated PMU.  Its purpose is solely to release
perf events that are no longer being actively used, and the meadiated PMU
obviously doesn't create perf events.

Subject: [PATCH 3135/5214] riscv: misaligned: Fix
 fast_unaligned_access_speed_key init

When booting with unaligned_scalar_speed=fast,
fast_unaligned_access_speed_key is initialized incorrectly.

The key is currently derived from the fast_misaligned_access cpumask, but
that mask is only populated when the unaligned access speed probe runs.
Specifying unaligned_scalar_speed=fast skips the probe entirely, leaving
the mask uninitialized.

The information tracked by fast_misaligned_access is already available in
the misaligned_access_speed per-CPU variable. Use that to initialize
fast_unaligned_access_speed_key instead and remove the redundant cpumask.

Subject: [PATCH 3136/5214] riscv: traps_misaligned: Avoid redundant unaligned
 access speed probe

When a CPU is taken offline and then is brought back online, unaligned
access speed probe always runs even though the unaligned access speed is
already known, wasting CPU cycles.

This is because when a CPU becomes online, the following happen:

  1. check_unaligned_access_emulated() is called, which clears
     misaligned_access_speed if there is no emulation.

  2. check_unaligned_access() is called because misaligned_access_speed is
     cleared, wasting CPU cycles determining something already previous
     known.

Avoid the redundant access speed probe by stop clearing
misaligned_access_speed in (1). If access speed is already known, just
reuse it.

On my Visionfive 2, this reduces CPU bring-up time from 26ms to 0.8ms.

Handle -NFS4ERR_OLD_STATEID in nfs4_layoutcommit_done().

This issue was reproduced on NFSv4.2.

Without refreshing data->args.stateid, LAYOUTCOMMIT can keep retrying
with the same stale stateid after OLD_STATEID, resulting in an
unbounded retry loop.

Refresh the layout stateid with nfs4_layout_refresh_old_stateid()
and restart the RPC only after a successful refresh.

Changes since v1: update refreshed stateid in inode layout header.

Subject: [PATCH 3138/5214] nfs: use nfsi->rwsem to protect traversal of the
 file lock list

Lingfeng identified a bug and suggested two solutions, but both appear
to have issues.

Generally, we cannot release flc_lock while iterating over the file lock
list to avoid use-after-free (UAF) problems with file locks. However,
functions like nfs_delegation_claim_locks and nfs4_reclaim_locks cannot
adhere to this rule because recover_lock or nfs4_lock_delegation_recall
may take a long time. To resolve this, NFS switches to using nfsi->rwsem
for the same protection, and nfs_reclaim_locks follows this approach.
Although nfs_delegation_claim_locks uses so_delegreturn_mutex instead,
this is inadequate since a single inode can have multiple nfs4_state
instances. Therefore, the fix is to also use nfsi->rwsem in this case.

Furthermore, after commit c69899a17ca4 ("NFSv4: Update of VFS byte range
lock must be atomic with the stateid update"), the functions
nfs4_locku_done and nfs4_lock_done also break this rule because they
call locks_lock_inode_wait without holding nfsi->rwsem. Simply adding
this protection could cause many deadlocks, so instead, the call to
locks_lock_inode_wait is moved into _nfs4_proc_setlk. Regarding the bug
fixed by commit c69899a17ca4 ("NFSv4: Update of VFS byte range
lock must be atomic with the stateid update"), it has been resolved
after commit 0460253913e5 ("NFSv4: nfs4_do_open() is incorrectly triggering
state recovery") because all slots are drained before calling
nfs4_do_reclaim, which prevents concurrent stateid changes along this path.
Also, nfs_delegation_claim_locks does not cause this concurrency either
since when _nfs4_proc_setlk is called with NFS_DELEGATED_STATE, no RPC is
sent, so nfs4_lock_done is not called. Therefore,
nfs4_lock_delegation_recall from nfs_delegation_claim_locks is the first
time the stateid is set.

Subject: [PATCH 3139/5214] pinctrl: qcom: Modify MSM_PULL_MASK to accurately
 represent PULL bits

MSM_PULL_MASK currently spans bits [2:0], but the GPIO_PULL field in the
GPIO_CFG register only occupies bits [1:0]. Bit 2 belongs to
FUNC_SEL.

MSM_PULL_MASK is used to isolate the GPIO_PULL bits before writing the
pull configuration (PULL_DOWN: 0x1, PULL_UP: 0x3) to the GPIO_CFG
register. Narrow it to bits [1:0] to prevent unintended modification of
the FUNC_SEL field.

This causes no functional change since the driver currently does not
modify the FUNC_SEL bit, but align the mask with hardware configuration
nonetheless.

Subject: [PATCH 3140/5214] pinctrl: qcom: Fix resolving register base address
 from device node

Commit 56ffb63749f4 ("pinctrl: qcom: add multi TLMM region option parameter")
added reg-names property based register reading. However multiple platforms
are not using the reg-names as they have only single TLMM register region.

Commit tried to handle this using the default_region module parameter,
however this condition is unreachable as the error return precedes it by
just checking if reg-names property exists or not, making it impossible
to use tlmm-test for the SoCs (x1e80100) which don't have reg-names
property in TLMM device.

Fix this by moving the default_region check at the start of the
tlmm_reg_base().

Subject: [PATCH 3141/5214] w1: ds2482: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

 bounds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The tape setup path uses one tape_block entry as the end-of-data marker
after the usable tape blocks. For the one-partition layout, partition 0
uses all TAPE_UNITS data slots and partition 1's marker is written at
tape_blocks[0] + TAPE_UNITS.

Only TAPE_UNITS entries are allocated, so that marker write is one
element past the allocation during device initialization before any
command is issued.

Allocate one extra tape_block entry for the marker. This keeps the
existing partitioning paths unchanged while providing backing storage
for the sentinel.

Subject: [PATCH 3146/5214] scsi: target: Fix hexadecimal CHAP_I handling

A mutual CHAP handshake requires target processing of an initiator-sent
CHAP_I identifier. The RFC 3720 specification states:

  11.1.4.  Challenge Handshake Authentication Protocol (CHAP)
  ...
  CHAP_A=<A> CHAP_I=<I> CHAP_C=<C>
  ...
  Where N, (A,A1,A2), I, C, and R are (correspondingly) the Name,
  Algorithm, Identifier, Challenge, and Response as defined in
  [RFC1994], N is a text string, A,A1,A2, and I are numbers

CHAP_I parsing currently calls extract_param(), which returns the
@identifier string (stripped of any 0b/0B or 0x/0X prefix) and a @type
which indicates DECIMAL, HEX, or BASE64 encoding (based on any stripped
prefix).

Any HEX encoded CHAP_I string is further processed via:

  ret = kstrtoul(&identifier[2], 0, &id);

This is incorrect for two reasons:

 * The @identifier string has already been stripped of the 0x/0X prefix,
   so skipping the first two bytes omits part of the number.

 * The kstrtoul() call specifies a base of 0, which will see
   &identifier[2] parsed as a decimal, unless a '0x' or (octal) '0' is
   erroneously present at that offset.

Fix this by passing the (zero-offset) identifier string to kstrtoul()
along with a base=16 parameter. Also add an explicit error handler for
BASE64 encoding.

Hex-encoded CHAP_I handling can be testing using the libiscsi EncodedI
test linked below.

Subject: [PATCH 3148/5214] nvme: quieten sparse warning in valid LBA size
 check

Currently building with C=1 generates the following warning:

  CC      drivers/nvme/host/core.o
  CHECK   drivers/nvme/host/core.c
drivers/nvme/host/core.c:2426:13: warning: unsigned value that used to be signed checked against zero?
drivers/nvme/host/core.c:2426:13: signed value source

This issue was introduced when using check_shl_overflow() to check for
invalid LBA size. Sparse is having trouble dealing with __bitwise __le64
conversion when passing to check_shl_overflow().

Resolve the issue by moving the check_shl_overflow() call to a separate
function, where types are not converted.

The id->lbaf[lbaf].ds < SECTOR_SHIFT check is dropped as
check_shl_overflow() is able to detect negative shifts.

Subject: [PATCH 3149/5214] scsi: devinfo: Broaden Promise VTrak E310/E610
 identification

The Promise VTrak Ex10 series share the same hardware base and firmware.
Consequently all interface variants, whether fibre channel ("f") or SAS
("s") in dual/single controller, exhibit the same SCSI behavior.

Instead of adding separate blacklist entries for every specific model
variant (such as E610f, E610s, E310f, E310s), consolidate and broaden
the match strings to "VTrak E310" and "VTrak E610".

Subject: [PATCH 3150/5214] scsi: ufs: core: Handle PM commands timeout before
 SCSI EH

A PM START STOP sent from the UFS well-known LU resume path can race
with SCSI EH:

The "wl resume" task flow is:
  __ufshcd_wl_resume()
    ufshcd_set_dev_pwr_mode(UFS_ACTIVE_PWR_MODE)
      ufshcd_execute_start_stop()
        scsi_execute_cmd()
          blk_execute_rq           <-- wait
          scsi_check_passthrough() <-- may retry START STOP

If the first START STOP time out, SCSI EH may already recover the link and
reset the device before scsi_execute_cmd() returns:

  scsi_timeout()
    scsi_eh_scmd_add()
      scsi_error_handler()
        scsi_unjam_host()
          scsi_eh_ready_devs()
            scsi_eh_host_reset()
              ufshcd_eh_host_reset_handler()
                if (hba->pm_op_in_progress)
                  ufshcd_link_recovery()
                    ufshcd_device_reset()
                    ufshcd_host_reset_and_restore()
          ...
          scsi_eh_flush_done_q()   <-- wakeup "wl resume" task
        ...                        <-- host still in SHOST_RECOVERY
        scsi_restart_operations()

A later passthrough retry can then run while the host is still in
SHOST_RECOVERY and hit the SCMD_FAIL_IF_RECOVERING path:

  scsi_queue_rq()
    if (scsi_host_in_recovery(shost) &&
        cmd->flags & SCMD_FAIL_IF_RECOVERING)
      return BLK_STS_OFFLINE

That retry completes with DID_ERROR or DID_NO_CONNECT even though EH may
already have restored the device to an operational ACTIVE state.

Handle these PM timeouts directly from ufshcd_eh_timed_out() instead.
After ufshcd_link_recovery(), complete the timed-out command immediately
if it has not been completed already.

For regular SCSI commands, complete them with DID_REQUEUE to match the
existing MCQ force-completion semantics and allow scsi_execute_cmd() to
retry if needed. For reserved internal device-management commands,
finish the request with DID_TIME_OUT without calling
ufshcd_release_scsi_cmd() since those commands use different resource
lifetime rules.

The system_suspending flag is no longer needed because PM command
timeout handling now uses pm_op_in_progress.

Subject: [PATCH 3152/5214] scsi: lpfc: Fix spelling mistakes in comments

Comment-only changes across the lpfc driver, found by running
scripts/checkpatch.pl with the kernel's scripts/spelling.txt list
against drivers/scsi/lpfc/.  No functional impact.

v1 covered a single site in lpfc_bsg.c.  v2 expands to all
checkpatch-detected comment misspellings across the driver, per review
feedback from Justin Tee on the v1 thread.  Identifiers that happen to
match common-typo entries (e.g. LSEXP_CANT_GIVE_DATA,
LPFC_FC_LA_TOP_UNKOWN) are intentionally left untouched, as renaming
them would change the driver's internal API.

Subject: [PATCH 3153/5214] scsi: target: Remove tcm_loop target reset handling

tcm_loop_target_reset is supposed to handle all the LUNs on a target but
it's only doing a TMR_LUN_RESET so only that one LUN is handled.  This
will cause us to return early while IOs to other LUNs are still hung in
lower layers. This just removes the target reset handler for the driver
because LIO doesn't support target resets and for the common case where
this is run from the scsi-ml error hamdler we have already tried an
abort and lun reset so waiting again is most likely useless.

Subject: [PATCH 3156/5214] KVM: x86/mmu: Recursively zap orphaned nested TDP
 shadow pages on emulated writes

Recursively zap orphaned nested TDP shadow pages when emulating a guest
write to a shadowed page table, regardless of whether or not the associated
(parent) shadow page will be zapped, e.g. due to detected write-flooding.

This plugs a hole where KVM fails to reclaim defunct, unsync shadow pages
for select L1 hypervisor patterns.  Commit 2de4085cccea ("KVM: x86/MMU:
Recursively zap nested TDP SPs when zapping last/only parent") modified KVM
to recursively zap synchronized shadow pages (KVM already recursively zaps
unsync children) when a child is orphaned.  But the fix effectively only
applied the logic to kvm_mmu_page_unlink_children(), i.e. only performs the
recursive zap when KVM is already zapping a parent SP and processing its
children.

If L1 zaps SPTEs bottom-up (4KiB => 2MiB => ...), as KVM's TDP MMU does
with CONFIG_KVM_PROVE_MMU=n since commit 8ca983631f3c ("KVM: x86/mmu: Zap
invalidated TDP MMU roots at 4KiB granularity"), then KVM (as L0) will leak
upwards of 4 shadow pages per GiB of L2 guest memory.  Over hundreds or
thousands of L2 boots, if the VM is "lucky" enough to escape write-flooding
detection, i.e. not trigger reclaim of the orphaned shadow pages by dumb
luck, then it's possible to end up with tens or even hundreds of thousands
of unsync shadow pages and associated rmap entries.

Polluting the hash table and rmap entries with a horde of stale entries
can eventually degrade L2 guest boot time by an order of magnitude,
especially if there is any antagonistic activity in the host, i.e. anything
that will contend for mmu_lock and/or needs to walk rmaps.

With "top"-down zapping, where "top" is 1GiB or above, then L0 KVM is
effectively limited to leaking 4 shadow pages per 256 GiB of memory, as
KVM's write flooding detection will kick in on the third write to an L1
TDP PUD, and thus recursively zap the entire 256 GiB range of the parent
PGD.  I.e. even though L1 KVM still recursively zaps 2MiB => 4KiB SPTEs
when zapping each 1GiB SPTE, KVM only gets through two of the 1GiB SPTEs
before dropping everything.  E.g. hacking tracing into L0 KVM's
kvm_mmu_track_write(), the top-down zapping of L1's TDP MMU for an L2 with
16GiB of memory leads to:

Contrast that with a bottom-up zap, which effectively allows all 2MiB SPTEs
in L1 to leak their children.

Note, in the shadow MMU, "level" describes the level a shadow page "points"
at, not the level of its associated SPTE. I.e.  when write-flooding of 1GiB
PUD entries is detected, KVM recursively zaps shadow pages covering 256GiB
worth of memory.  And as shown above, KVM's write-flooding detection
operates at all levels, so a single PMD (in L1) can effectively only leak
two unsync children (4KiB shadow pages) before it gets recursively zapped.
As a result, for the top-down zap, L0 KVM will leak at most 4 unsync shadow
pages per 256GiB of L2 memory.

The top-down zap also makes it more likely that L1 will self-heal (to some
extent), as any shadow pages that are "rediscovered" by future runs of L2
can get reclaimed by a recursive zap, whereas bottom-up zapping orphans
shadow pages over and over.

Note, in theory, there is some risk of over-zapping, e.g. due to zapping a
a large branch of the paging tree that L1 is only temporarily removing.  In
practice, the usage patterns of hypervisors are highly unlikely to trigger
false positives.  E.g. temporarily changing paging protections is typically
done at the leaf, not on a non-leaf entry.  And if the L1 hypervisor is
updating large swaths of PTEs, e.g. to (temporarily?) remove chunks of
memory from L2, then L0 KVM's write-flooding detection will kick in, and
the children would be zapped anyways.

Commit e785c990adcc ("pinctrl: Kconfig: drop unneeded dependencies

several pinctrl drivers, but this change also removed a dependency
on CONFIG_OF for some of those drivers.

Normally, this wouldn't be a problem, but PINCTRL_STMFX also selected
MFD_STMFX, which does depend on CONFIG_OF.  This conflict allows
MFD_STMFX to be enabled even if CONFIG_OF is disabled.

Fix this by also having PINCTRL_STMFX depend on CONFIG_OF.  This is
okay because the pinctrl-stmfx driver actually does depend on CONFIG_OF
functions.

 return types

Commit 0dfe54071d7c8 ("nodemask: Fix return values to be unsigned")
changed a number of nodemask operations that used to return int to
returning a bool instead.  However, it did not update the comment block
that described these functions, leaving the documentation incorrect.

Fix the comment block to accurately describe the functions.  Also fix a
typo (unsigend --> unsigned), and fix a callsite in mempolicy.c that did
not get updated during the conversion.

No functional changes intended; changes are purely cosmetic.

Subject: [PATCH 3161/5214] mm: list_lru: fix set_shrinker_bit() call during
 race with cgroup deletion

Patch series "mm: switch THP shrinker to list_lru", v5.

The open-coded deferred split queue has issues.  It's not NUMA-aware (when
cgroup is enabled), and it's more complicated in the callsites interacting
with it.  Switching to list_lru fixes the NUMA problem and streamlines
things.  It also simplifies planned shrinker work.

Patch 1 fixes a pre-existing list_lru bug where the shrinker bit is set on
the caller's memcg rather than the ancestor whose sublist the item
actually lands on after a walk-up.  Standalone, backportable; the rest of
the series depends on it.

Patches 2-5 are cleanups and small refactors in list_lru code.  They're
basically independent, but make the THP shrinker conversion easier.

Patch 6 extends the list_lru API to allow the caller to control the
locking scope.  The THP shrinker has private state it needs to keep
synchronized with the LRU state.

Patch 7 extends the list_lru API with a convenience helper to do list_lru
head allocation (memcg_list_lru_alloc) when coming from a folio.  Anon
THPs are instantiated in several places, and with the folio reparenting
patches pending, folio_memcg() access is now a more delicate dance.  This
avoids having to replicate that dance everywhere.

Patch 8 flattens the alloc_anon_folio() retry loop so the next patch's
list_lru hook lands as a clean addition rather than nested deep inside an
if (folio) block.

Patch 9 finally switches the deferred_split_queue to list_lru.


This patch (of 9):

When list_lru_add() races with cgroup deletion, the shrinker bit is set on
the wrong group and lost.  This can cause a shrinker run to miss the
cgroup that actually has the object.

When the passed in memcg is dead, the function finds the first non-dead
parent from the passed in memcg and adds the object there; but the
shrinker bit is set on the memcg that was passed in.

This bug is as old as the shrinker bitmap itself.

Fix it by returning the "effective" memcg from the locking function, and
have the caller use that.

Subject: [PATCH 3162/5214] mm: list_lru: lock_list_lru_of_memcg() cannot
 return NULL if !skip_empty

skip_empty is only for the shrinker to abort and skip a list that's empty
or whose cgroup is being deleted.

For list additions and deletions, the cgroup hierarchy is walked upwards
until a valid list_lru head is found, or it will fall back to the node
list.  Acquiring the lock won't fail.  Remove the NULL checks in those
callers.

caller, so that the next patch can unify the lock_list_lru() variants.

Subject: [PATCH 3166/5214] mm: list_lru: introduce caller locking for
 additions and deletions

Locking is currently internal to the list_lru API.  However, a caller
might want to keep auxiliary state synchronized with the LRU state.

For example, the THP shrinker uses the lock of its custom LRU to keep
PG_partially_mapped and vmstats consistent.

To allow the THP shrinker to switch to list_lru, provide normal and
irqsafe locking primitives as well as caller-locked variants of the
addition and deletion functions.

Subject: [PATCH 3167/5214] mm: list_lru: introduce
 folio_memcg_list_lru_alloc()

memcg_list_lru_alloc() is called every time an object that may end up on
the list_lru is created.  It needs to quickly check if the list_lru heads
for the memcg already exist, and allocate them when they don't.

Doing this with folio objects is tricky: folio_memcg() is not stable and
requires either RCU protection or pinning the cgroup.  But it's desirable
to make the existence check lightweight under RCU, and only pin the memcg
when we need to allocate list_lru heads and may block.

In preparation for switching the THP shrinker to list_lru, add a helper
function for allocating list_lru heads coming from a folio.

Subject: [PATCH 3168/5214] mm: memory: flatten alloc_anon_folio() retry loop

alloc_anon_folio() uses a top-level if (folio) that buries the success
path four levels deep.  This makes for awkward long lines and wrapping.
The next patch will add more code here, so flatten this now to keep things
clean and simple.

The next label is already there, use it for !folio.

No functional change intended.

Subject: [PATCH 3169/5214] mm: switch deferred split shrinker to list_lru

The deferred split queue handles cgroups in a suboptimal fashion.  The
queue is per-NUMA node or per-cgroup, not the intersection.  That means on
a cgrouped system, a node-restricted allocation entering reclaim can end
up splitting large pages on other nodes:

        alloc/unmap
          deferred_split_folio()
            list_add_tail(memcg->split_queue)
            set_shrinker_bit(memcg, node, deferred_shrinker_id)

        for_each_zone_zonelist_nodemask(restricted_nodes)
          mem_cgroup_iter()
            shrink_slab(node, memcg)
              shrink_slab_memcg(node, memcg)
                if test_shrinker_bit(memcg, node, deferred_shrinker_id)
                  deferred_split_scan()
                    walks memcg->split_queue

The shrinker bit adds an imperfect guard rail.  As soon as the cgroup has
a single large page on the node of interest, all large pages owned by that
memcg, including those on other nodes, will be split.

list_lru properly sets up per-node, per-cgroup lists.  As a bonus, it
streamlines a lot of the list operations and reclaim walks.  It's used
widely by other major shrinkers already.  Convert the deferred split queue
as well.

The list_lru per-memcg heads are instantiated on demand when the first
object of interest is allocated for a cgroup, by calling
folio_memcg_alloc_deferred().  Add calls to where splittable pages are
created: anon faults, swapin faults, khugepaged collapse.

These calls create all possible node heads for the cgroup at once, so the
migration code (between nodes) doesn't need any special care.

Subject: [PATCH 3170/5214] mm/thp: clear deferred split shrinker bits when
 queues drain

deferred_split_count() returns the raw list_lru count.  When the
per-memcg, per-node list is empty, that count is 0.

That skips scanning, but it does not tell memcg reclaim that the shrinker
is empty.  shrink_slab_memcg() only clears the memcg shrinker bit when the
count callback reports SHRINK_EMPTY.

Return SHRINK_EMPTY for an empty deferred split list, so the bit can be
cleared once the queue has drained.

Subject: [PATCH 3171/5214] mm/compaction: respect cpusets when checking retry
 suitability

should_compact_retry() handles COMPACT_SKIPPED by asking
compaction_zonelist_suitable() whether reclaim can make a later compaction
attempt worthwhile.  That answer is used for the current allocation, so it
should follow the same zone eligibility rules as the allocation itself.

When cpusets are enabled, allocator slowpath decisions are marked with
ALLOC_CPUSET.  The allocation path, direct compaction and reclaim retry
all skip zones rejected by __cpuset_zone_allowed().

compaction_zonelist_suitable() does not apply that filter.  It only walks
ac->zonelist/ac->nodemask, so it can return true because a zone that is
not usable for the current allocation would pass __compaction_suitable().

That does not let the allocation use the disallowed zone.  Later
allocation and direct compaction paths still apply cpuset filtering.
However, it can make should_compact_retry() retry based on memory that
this allocation cannot use.

Pass gfp_mask down and apply the same ALLOC_CPUSET check in
compaction_zonelist_suitable().  This keeps the retry decision aligned
with the zones that the allocation is allowed to use.

A temporary debugfs probe was also used to call the old and new
compaction_zonelist_suitable() predicates in the same two-node NUMA guest.
The task was restricted to mems=0 while ac->nodemask covered nodes 0-1.
After putting pressure on node0, node0 failed __compaction_suitable() for
order-10 and node1 passed it, but node1 was rejected by
__cpuset_zone_allowed().  In that state the old predicate returned true
and the patched predicate returned false.

Subject: [PATCH 3172/5214] mm: bypass mmap_miss heuristic for VM_EXEC
 readahead

Patch series "mm: improve large folio readahead for exec memory", v7.

Two checks in do_sync_mmap_readahead() limit large-folio readahead:

  1. The mmap_miss heuristic is meant to throttle wasteful speculative
     readahead. It is currently also applied to the VM_EXEC readahead
     path, which is targeted rather than speculative. Once mmap_miss exceeds
     MMAP_LOTSAMISS, exec readahead - including the large-folio
     order requested by exec_folio_order() - is disabled. On
     configurations where the mmap_miss decrement paths are not
     active (see patch 1) the counter only grows, so exec readahead
     is permanently disabled after the first 100 faults.

  2. The force_thp_readahead path is gated only on
     HPAGE_PMD_ORDER <= MAX_PAGECACHE_ORDER and always drives the
     readahead at HPAGE_PMD_ORDER. Configurations where
     HPAGE_PMD_ORDER exceeds MAX_PAGECACHE_ORDER never reach this
     path, even when the mapping itself supports usefully large
     folios well below the cap.

Both issues are most visible on arm64 with a 64K base page size, where
HPAGE_PMD_ORDER is 13 (512MB) -- above MAX_PAGECACHE_ORDER (11) -- and
where fault_around_pages collapses to 1 disabling should_fault_around()
(one of the two mmap_miss decrement sites).  However the fixes are
architecture-agnostic: patch 1 reflects the nature of VM_EXEC readahead
regardless of base page size, and patch 2 generalises the gate so any
mapping advertising a usefully large maximum folio order can benefit.

I created a benchmark that mmaps a large executable file madvises it as
huge and calls RET-stub functions at PAGE_SIZE offsets across it.  "Cold"
measures fault + readahead cost.  "Random" first faults in all pages with
a sequential sweep (not measured), then measures time for calling random
offsets, isolating iTLB miss cost for scattered execution.

The benchmark results on Neoverse V2 (Grace), arm64 with 64K base pages,
512MB executable file on ext4, averaged over 3 runs:

  Phase      | Baseline     | Patched      | Improvement
  -----------|--------------|--------------|------------------
  Cold fault | 83.4 ms      | 41.3 ms      | 50% faster
  Random     | 76.0 ms      | 58.3 ms      | 23% faster


This patch (of 2):

The mmap_miss heuristic is intended to stop speculative mmap readahead
when a file looks like a random-access workload.  That does not fit the
VM_EXEC path very well.

VM_EXEC readahead is already constrained differently from ordinary mmap
read-around: it is bounded by the VMA, uses exec_folio_order() to choose
an order useful for executable mappings, and sets async_size to 0 so it
does not create follow-on readahead.  When VM_HUGEPAGE is also present,
the larger readahead is an explicit userspace opt-in.

The mmap_miss counter is decremented from cache-hit paths in
do_async_mmap_readahead() and filemap_map_pages().  Those paths are not
always enough to balance the synchronous miss increments for executable
mappings.  In particular, when fault-around is effectively disabled, such
as configurations where fault_around_pages is 1, filemap_map_pages() is
not reached from the fault path.  The counter can then become a stale
throttle for VM_EXEC mappings and suppress the readahead behavior that the
executable-specific path is trying to provide.

Skip both mmap_miss increments and decrements for VM_EXEC mappings,
matching the existing VM_SEQ_READ treatment and keeping the counter
accounting symmetric.

Subject: [PATCH 3173/5214] mm: use mapping_max_folio_order() for
 force_thp_readahead order

The force_thp_readahead path in do_sync_mmap_readahead() is gated on
HPAGE_PMD_ORDER <= MAX_PAGECACHE_ORDER and always requests HPAGE_PMD_ORDER
/ HPAGE_PMD_NR.  On configurations where HPAGE_PMD_ORDER exceeds
MAX_PAGECACHE_ORDER, notably arm64 with a 64K base page size, VM_HUGEPAGE
mappings cannot use this path and fall back to the non-forced mmap
readahead path even when the mapping supports useful large folios.

Enable forced readahead for mappings that support large folios and request
the max folio order supported by the mapping, capped at 2M.  2MB is chosen
as the cap because it matches the PMD size on x86_64 and on arm64 with 4K
base pages, so the size/memory-pressure tradeoff for folios of that size
is already well understood.  On arm64 with 16K and 64K base page sizes,
2MB is also the contiguous-PTE (contpte) block size, so the resulting
folios coalesce into a single TLB entry and reduce TLB pressure on the
readahead path.  This will result in 32M folios not being faulted in with
16K base page size for arm64, but with contpte, the performance difference
should be negligible.

The final allocation order may still be clamped by page_cache_ra_order()
to the mapping and request geometry, but this gives VM_HUGEPAGE mappings
on such configurations a large-folio readahead request instead of dropping
back to base-page readahead.

Subject: [PATCH 3174/5214] mm/page_alloc: fix deferred compaction accounting

COMPACT_DEFERRED means compaction did not start because past failures
caused the zone to be deferred.  try_to_compact_pages() returns the
maximum result seen while walking the zonelist, so a final
COMPACT_DEFERRED result means no later zone reported that compaction
actually ran.

__alloc_pages_direct_compact() skips COMPACTSTALL and COMPACTFAIL
accounting when try_to_compact_pages() returns COMPACT_SKIPPED, but not
when it returns COMPACT_DEFERRED.  A deferred-only direct compaction
attempt can therefore look like a stall, and then a failure if the
allocation still cannot be satisfied.

Treat COMPACT_DEFERRED like COMPACT_SKIPPED in this accounting path.  If a
later zone runs compaction and returns a result above COMPACT_DEFERRED, or
compact_zone_order() reports COMPACT_SUCCESS for a captured page, the
final result is not COMPACT_DEFERRED and the existing accounting still
runs.

longer needs the parent bio.  Mirror the read side
(zram_bvec_read_partial() has not taken a bio since commit 4e3c87b9421d
("zram: fix synchronous reads")) and drop the parameter from
zram_bvec_write_partial() and zram_bvec_write().

No functional change.

Subject: [PATCH 3180/5214] fs/proc/task_mmu: fix make_uffd_wp_huge_pte()
 prot-update race

Patch series "userfaultfd/pagemap: pre-existing fixes".

These are pre-existing bug fixes that were carried at the front of the
userfaultfd RWP working-set-tracking series up to v5 [1].  Per review
feedback that fixes should not sit in the middle of a feature series, they
are split out and sent on their own; the RWP series is reposted rebased on
top of this.

All six were flagged by the Sashiko AI review of the RWP series and carry
Reported-by: Sashiko AI review <sashiko-bot@kernel.org>.  They are
independent of RWP, apply to mm-new directly, and carry Cc: stable@.

  1: fs/proc/task_mmu: a missing huge_ptep_modify_prot_start() in
     make_uffd_wp_huge_pte() can lose hardware Dirty/Accessed updates
     when PAGEMAP_SCAN write-protects a hugetlb PTE.

  2: fs/proc/task_mmu: pagemap_scan_hugetlb_entry() compares the range
     against HPAGE_SIZE rather than the hstate page size, so it never
     write-protects gigantic hugetlb pages.

  3: fs/proc/task_mmu: PAGEMAP_SCAN with PM_SCAN_WP_MATCHING over an
     unpopulated hugetlb range self-deadlocks -- pagemap_scan_pte_hole()
     calls uffd_wp_range() while walk_hugetlb_range() holds the hugetlb
     vma lock for read, and hugetlb_change_protection() then takes it
     for write. Install the marker inline instead.

  4: mm/huge_memory: change_non_present_huge_pmd() drops pmd_swp_uffd_wp
     on a device-private PMD permission downgrade, silently losing the
     uffd-wp marker.

  5: userfaultfd: must_wait() applies pte_write() to a locklessly read
     PTE without checking pte_present(), so swap/migration entries
     decode random offset bits and a thread can stay parked on a stale
     fault.

  6: userfaultfd: __VMA_UFFD_FLAGS feeds VMA_UFFD_MINOR_BIT (41) to
     mk_vma_flags() unconditionally, an out-of-bounds write into the
     single-word vma_flags_t on 32-bit. Build the mask from config-gated
     per-mode masks so an unavailable bit is never materialised.


This patch (of 6):

make_uffd_wp_huge_pte() arms the UFFD_WP bit on a present HugeTLB PTE by
calling huge_ptep_modify_prot_commit() with a ptent snapshot that was
fetched without the corresponding huge_ptep_modify_prot_start().  The
start helper is what atomically clears the entry so the kernel-owned
snapshot stays consistent until the commit; without it, the hardware may
set Dirty or Accessed in the live PTE between the original read and the
commit, and huge_ptep_modify_prot_commit() (whose generic implementation
just calls set_huge_pte_at()) then writes the stale snapshot back over the
live hardware bits, losing the update.

The non-hugetlb sibling make_uffd_wp_pte() does this correctly via
ptep_modify_prot_start() / ptep_modify_prot_commit().  Mirror that pattern
for the present-PTE branch.  The migration case stays as-is -- migration
entries are non-present, so there's no hardware update to race against.

Subject: [PATCH 3181/5214] fs/proc/task_mmu: use huge_page_size() in
 pagemap_scan_hugetlb_entry()

The partial-page check compares against HPAGE_SIZE (PMD_SIZE), which is
wrong for gigantic hugetlb hstates (e.g.  1G).  The walker hands the
callback a huge_page_size()-sized range, never start + HPAGE_SIZE, so the
comparison always declares it partial and aborts the WP.  Compare against
the actual hstate's page size.

Subject: [PATCH 3182/5214] fs/proc/task_mmu: fix hugetlb self-deadlock in
 pagemap_scan_pte_hole()

A PAGEMAP_SCAN ioctl requesting PM_SCAN_WP_MATCHING on a hugetlb VMA hangs
the calling thread, unkillably, as soon as the scan reaches an unpopulated
part of the range:

  do_pagemap_scan()
    walk_page_range()
      walk_hugetlb_range()
        hugetlb_vma_lock_read()           # take the vma lock for read ...
        pagemap_scan_pte_hole()           # ... ->pte_hole() for a hole
          uffd_wp_range()
            change_protection()
              hugetlb_change_protection()
                hugetlb_vma_lock_write()  # ... and block taking it for write

walk_hugetlb_range() holds the hugetlb vma lock for read across the whole
walk.  A present entry goes to ->hugetlb_entry(); an unpopulated one goes
to ->pte_hole(), i.e.  pagemap_scan_pte_hole().  To write-protect the hole
that handler calls uffd_wp_range(), which on a hugetlb VMA reaches
hugetlb_change_protection() and takes the same vma lock for write.  The
thread then blocks in down_write() waiting for the read lock it is itself
holding.

The populated path avoids this: pagemap_scan_hugetlb_entry()
write-protects the entry inline under the page-table lock and never enters
hugetlb_change_protection().

Do the same for holes.  Fault in the page table and install the uffd-wp
marker directly with make_uffd_wp_huge_pte() under the page-table lock,
rather than routing through uffd_wp_range().  That is the same sequence
hugetlb_change_protection() runs for an unpopulated entry, minus the vma
write lock -- which is safe to skip because PMD sharing is disabled on
uffd-wp VMAs (hugetlb_unshare_all_pmds() runs at registration), leaving
nothing for that lock to serialise against.

Subject: [PATCH 3183/5214] mm/huge_memory: preserve pmd_swp_uffd_wp on
 device-private PMD downgrade

change_non_present_huge_pmd() rewrites a writable device-private PMD swap
entry into a readable one without carrying pmd_swp_uffd_wp() across.  The
PTE-level change_softleaf_pte() does this correctly; mirror that here,
matching what copy_huge_pmd() does for the fork path.  Without the carry,
a plain mprotect() over a UFFD_WP-marked device-private THP strips the bit
and the trap is bypassed on swap-in.

Subject: [PATCH 3184/5214] userfaultfd: gate must_wait writability check on
 pte_present()

userfaultfd_must_wait() and userfaultfd_huge_must_wait() read the PTE
without taking the page table lock and then apply pte_write() /
huge_pte_write() to it.  Those accessors decode bits from the present
encoding only; on a swap or migration entry they read the offset bits that
happen to share the same position and return an undefined result.

The intent of the check is "is this fault still WP-blocked?".  A
non-marker swap entry means the page is in transit -- the userfault
context the original fault delivered against is no longer the same, and
the swap-in or migration completion path will re-deliver a fresh fault if
userspace still needs to handle it.  Worst case under the current code the
garbage write bit says "wait", and the thread stays asleep until a
UFFDIO_WAKE that may never arrive.

Gate the writability check on pte_present() so the lockless re-check only
inspects present-PTE bits when the entry is actually present.  The
non-present, non-marker case returns "don't wait" and lets the fault path
retry.

Subject: [PATCH 3185/5214] userfaultfd: build __VMA_UFFD_FLAGS from
 config-gated masks

The VMA flags bitmap is a single word today: NUM_VMA_FLAG_BITS is
BITS_PER_LONG, so on 32-bit vma_flags_t holds only 32 bits.  (The bitmap
type exists so this can grow past BITS_PER_LONG later; until it does,
anything declared above the first word is out of range on 32-bit.) The bit
enum nevertheless declares some bits unconditionally above BITS_PER_LONG
-- VMA_UFFD_MINOR_BIT is 41, with VM_UFFD_MINOR == VM_NONE on 32-bit so no
VMA actually carries the bit.

__VMA_UFFD_FLAGS feeds VMA_UFFD_MINOR_BIT to mk_vma_flags()
unconditionally.  On 32-bit that becomes __set_bit(41, &one_long), a write
one word past the end of the single-word bitmap.  The compiler folds the
out-of-bounds store with wraparound (1UL << (41 % 32) == bit 9) into the
first word; bit 9 is already in __VMA_UFFD_FLAGS so the mask happens to
come out right today, but it is an out-of-bounds write all the same, and
any high-numbered bit whose mod-BITS_PER_LONG position is otherwise unused
would silently OR an extra bit into the mask.

Rather than feed bit numbers that may not exist on the current build to
mk_vma_flags(), build the mask from whole per-mode masks that collapse to
EMPTY_VMA_FLAGS when their feature is unavailable.  Add
mk_vma_flags_from_masks() for that, and define VMA_UFFD_MISSING / _WP /
_MINOR alongside the VM_UFFD_* flags, gating VMA_UFFD_MINOR on the same
config as VM_UFFD_MINOR (which implies 64BIT, where bit 41 fits).  An
out-of-range bit is then never materialised, on any arch, and the in-range
fast path stays a compile-time constant.

Subject: [PATCH 3186/5214] rust: page: mark Page::nid as inline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When building the kernel, the following Rust symbol is generated:

  $ nm vmlinux | grep ' _R'.*Page | rustfilt
  <kernel::page::Page>::nid

`Page::nid` is a trivial wrapper around the C function `page_to_nid`.  It
does not make sense to go through a trivial wrapper for this function, so
mark it inline.

This follows commit 878620c5a93a ("rust: page: optimize rust symbol
generation for Page"), which did the same for `alloc_page` and `drop`.

Subject: [PATCH 3187/5214] mm/sparse-vmemmap: provide generic
 vmemmap_set_pmd() and vmemmap_check_pmd()

Patch series "mm/sparse-vmemmap: Provide generic vmemmap_set_pmd() and
vmemmap_check_pmd()", v3.

The weak vmemmap_set_pmd() and vmemmap_check_pmd() hooks are currently
no-ops in the generic code, which leaves architectures that need PMD-level
handling to open-code the same logic locally.

This series provides generic implementations for both helpers in
mm/sparse-vmemmap.c.  vmemmap_set_pmd() installs a huge PMD with
PAGE_KERNEL protection, and vmemmap_check_pmd() verifies a present leaf
PMD before reusing the existing vmemmap_verify() helper.

With those generic helpers in place, patches 2-5 remove the now redundant
arch-specific implementations from arm64, riscv, loongarch, and sparc.


This patch (of 5):

The two weak functions are currently no-ops on every architecture, forcing
each platform that needs them to duplicate the same handful of lines.
Provide a generic implementation:

- vmemmap_set_pmd() simply sets a huge PMD with PAGE_KERNEL protection.

- vmemmap_check_pmd() verifies that the PMD is present and leaf,
  then calls the existing vmemmap_verify() helper.

Architectures that need special handling can continue to override the weak
symbols; everyone else gets the standard version for free.

Subject: [PATCH 3194/5214] mm/swap, PM: hibernate: fix swapoff race in uswsusp
 by pinning swap device

Patch series "mm/swap, PM: hibernate: fix swapoff race in uswsusp by
pinning swap device", v8.

Currently, in the uswsusp path, only the swap type value is retrieved at
lookup time without holding a reference. If swapoff races after the type
is acquired, subsequent slot allocations operate on a stale swap device.

Additionally, grabbing and releasing the swap device reference on every
slot allocation is inefficient across the entire hibernation swap path.

This patch series addresses these issues:
- Patch 1: Fixes the swapoff race in uswsusp by pinning the swap device
  from the point it is looked up until the session completes.
- Patch 2: Removes the overhead of per-slot reference counting in alloc/free
  paths and cleans up the redundant SWP_WRITEOK check.


This patch (of 2):

Hibernation via uswsusp (/dev/snapshot ioctls) has a race window: after
selecting the resume swap area but before user space is frozen, swapoff
may run and invalidate the selected swap device.

Fix this by pinning the swap device with SWP_HIBERNATION while it is in
use.  The pin is exclusive, which is sufficient since hibernate_acquire()
already prevents concurrent hibernation sessions.

The kernel swsusp path (sysfs-based hibernate/resume) uses
find_hibernation_swap_type() which is not affected by the pin.  It freezes
user space before touching swap, so swapoff cannot race.

Introduce dedicated helpers:
- pin_hibernation_swap_type(): Look up and pin the swap device.
  Used by the uswsusp path.
- find_hibernation_swap_type(): Lookup without pinning.
  Used by the kernel swsusp path.
- unpin_hibernation_swap_type(): Clear the hibernation pin.

While a swap device is pinned, swapoff is prevented from proceeding.

Subject: [PATCH 3195/5214] mm/swap: remove redundant swap device reference in
 alloc/free

In the previous commit, uswsusp was modified to pin the swap device when
the swap type is determined, ensuring the device remains valid throughout
the hibernation I/O path.

Therefore, it is no longer necessary to repeatedly get and put the swap
device reference for each swap slot allocation and free operation.

For hibernation via the sysfs interface, user-space tasks are frozen
before swap allocation begins, so swapoff cannot race with allocation.
After resume, tasks remain frozen while swap slots are freed, so
additional reference management is not required there either.

Remove the redundant swap device get/put operations from the hibernation
swap allocation and free paths.

Also remove the SWP_WRITEOK check before allocation, as the cluster
allocation logic already validates the swap device state.

Update function comments to document the caller's responsibility for
ensuring swap device stability.

Subject: [PATCH 3196/5214] mm/compaction: cap compact_gap() at
 COMPACT_CLUSTER_MAX

compact_gap() returns 2 << order, which is used as watermark headroom in
__compaction_suitable() and as a threshold in kswapd reclaim decisions.
The computed value scales exponentially by order.  For order-9 THP
allocations this evaluates to 1024 pages, but the compaction free
scanner's working set is bounded by COMPACT_CLUSTER_MAX (32 pages).  The
scanner stops isolating free pages once it matches the migration batch.
The current gap over-reserves by 32x.

On fragmented production hosts, kswapd will try to reclaim up to the gap,
but it only reaches that threshold in 18% of attempts.  As a result,
reclaim continues in the majority of cases despite many lower-order free
pages being available.  The over-sized gap also causes 46% of order-9
compaction suitability checks to fail unnecessarily: the zone has
sufficient free pages for the scanner to operate, but not enough to clear
the inflated threshold.

Cap compact_gap() at COMPACT_CLUSTER_MAX so the watermark headroom
reflects the scanner's actual capacity.  This function is used by two key
heuristics.  The first is when kswapd can stop high-order reclaim and
downgrade to order-0 balancing, allowing kcompactd to be woken for the
original higher allocation order.  The second is zone suitability
checking, where the smaller gap allows compaction to start sooner.

Note that orders 0-4 are unaffected since their gap is already less than
or equal to COMPACT_CLUSTER_MAX.

A/B test on v6.13-based instagram production hosts (64GB, 60s
measurement):

Unpatched (43 hosts)
pgscan_kswapd (mean/host): ~1.6M
reclaim efficiency (steal/scan): 83.8%
per-compaction success (success/stall): 2.1%
THP success (alloc/alloc+fallback): 4.9%
forced lru_add_drain (mean/host): ~107K

Patched (59 hosts)
pgscan_kswapd (mean/host): ~449K
reclaim efficiency (steal/scan): 91.0%
per-compaction success (success/stall): 28.3%
THP success (alloc/alloc+fallback): 17.2%
forced lru_add_drain (mean/host): ~64K

Additional tests were also performed using a workload of similar shape and
based on mm-new at the time of testing.  Across three 60s runs, the patch
showed improvements consistent with the previous test: reduced kswapd
reclaim and fewer THP fault fallbacks.

Unpatched
kswapd_shrink_node downgrade to order-0 (mean): 0
thp_fault_fallback (mean): 1217
pgscan_kswapd (mean): 6328
pgsteal_kswapd (mean): 5657

Patched
kswapd_shrink_node downgrade to order-0 (mean): 28
thp_fault_fallback (mean): 738
pgscan_kswapd (mean): 3773
pgsteal_kswapd (mean): 3243

Subject: [PATCH 3198/5214] fs/proc/task_mmu: do not warn on seeing
 non-migration pmd entry

Patch series "mm/hmm: A fix and a selftest", v3.

Patch 1 fixes a stale warning present from the time when only migration
softleaf entries were supported at the PMD level.

Patch 2 adds some code into hmm-tests.c which exercises the pagemap path
for PMD device-private entries.


This patch (of 2):

pagemap_pmd_range_thp() warns if a non-present PMD is not a migration
entry.  This became false once device-private entries at the PMD level
were added.

Therefore, remove the stale migration-only assertion.

 device-private entries

To cover pagemap paths scanning PMD entries, add assertions to check
whether a device-private PMD entry has the correct pagemap information -
the PM_SWAP bit must be on in the pagemap entry.  Before that, we must
assert through HMM_DMIRROR_SNAPSHOT snapshot that the leaf entry is at PMD
level and not PTE level.

Subject: [PATCH 3202/5214] remoteproc: qcom_q6v5_wcss: drop redundant
 wcss_q6_bcr_reset

The wcss_q6_bcr_reset used on QCS404, and wcss_q6_reset used on IPQ
are the same. "BCR reset" is redundant, and likely a mistake. Use the
documented "wcss_q6_reset" instead. Drop ".wcss_q6_reset_required"
from the descriptor, since all targets now need it.

This changes the bindings expectations, however, it actually fixes the
driver to consume the intended ones (qcom,q6v5.txt), which lists
"wcss_q6_reset" and *not* "wcss_q6_bcr_reset"

Fixes: 0af65b9b915e ("remoteproc: qcom: wcss: Add non pas wcss Q6 support for QCS404")

Subject: [PATCH 3203/5214] remoteproc: qcom: Fix leak when custom
 dump_segments addition fails

Free allocated minidump_region 'name' in qcom_add_minidump_segments()
when failing before adding the region to 'dump_segments'. Otherwise,
the 'name' is not tracked and is never freed by qcom_minidump_cleanup().

Return error when adding to 'dump_segments' fails.

Subject: [PATCH 3210/5214] platform/x86: oxpec: add support for OneXPlayer
 Super X
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

OneXPlayer Super X identifies itself via DMI as:

  board vendor: ONE-NETBOOK
  board name:   ONEXPLAYER SUPER X
  product name: ONEXPLAYER SUPER X

Current mainline oxpec does not contain a matching DMI entry for this
system, so the in-tree driver is not auto-loaded.

The tested Super X fan, PWM, turbo-toggle, and battery charge-control EC
layout matches the existing ONEXPLAYER G1 A handling.

Add a DMI match for OneXPlayer Super X and reuse the oxp_g1_a board data.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In mem_write(), the temporary array returned by
parse_int_array_user() must be released on all exit paths.
Convert the array variable to use cleanup.h scope-based
cleanup so it is freed automatically on return.

This also moves the array declaration next to
parse_int_array_user() as required by cleanup.h usage
guidelines.

Subject: [PATCH 3213/5214] platform/x86/intel/pmc: rate-limit LTR scale-factor
 warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

convert_ltr_scale() emits an unconditional pr_warn() whenever an LTR row
encoded by hardware has a scale-factor field of 6 or 7 (reserved values
per the PCIe LTR ECN).  The function is called twice per LTR row (snoop
+ non-snoop) by pmc_core_ltr_show(), which is invoked on every read of
/sys/kernel/debug/pmc_core/ltr_show as well as during certain platform
driver activity.

On a Meteor Lake laptop with an Intel AX210 Wi-Fi card, this produces
4-12 "Invalid LTR scale factor." lines per second in dmesg, with no
context to help identify which PMC IP / row carries the bad value.

Switch to pr_warn_once() so the warning still flags the spec violation
once per boot, and include the offending scale value in the message.
Identifying the originating LTR row would require restructuring the
caller's loop to perform the validity check itself; that is left as a
separate change.

The HP Omen 16-ap0xxx (board ID: 8D26) has the same WMI interface as
other Victus S boards, but requires quirks for correctly switching
thermal profile.

Add the DMI board name to victus_s_thermal_profile_boards[] table and
map it to omen_v1_legacy_thermal_params.

Testing on board 8D26 confirmed that platform profile is registered
successfully and fan RPMs are readable and controllable.

Subject: [PATCH 3217/5214] fs/ntfs3: bound NTFS_DE view.data_off in
 UpdateRecordData{Root,Allocation}

In do_action()'s UpdateRecordDataRoot (fslog.c:3489) and
UpdateRecordDataAllocation (fslog.c:3697) cases, the memmove
destination is `Add2Ptr(e, le16_to_cpu(e->view.data_off))`,
where e->view.data_off comes from an on-disk NTFS_DE inside
an INDEX_ROOT or INDEX_BUFFER.  Neither case validates
view.data_off + dlen against e->size; the existing
check_if_index_root / check_if_alloc_index helpers walk the
entry chain and validate the entry's offset, but not its
internal view fields.

The neighbouring read sites (e.g., fs/ntfs3/index.c when
iterating view entries) check view.data_off + view.data_size
<= e->size.  Apply the same bound at the two memmove sites.

Reproduced under UML+KASAN on mainline 8d90b09e6741 via
pr_warn-only probe instrumentation: with view.data_off forced
to 0xFFFC, the memmove writes 32 bytes past the end of the
NTFS_DE.

This is similar in shape to Pavitra Jha's 2026-05-02 patch
"fs/ntfs3: prevent oob in case UpdateRecordDataRoot"
(<20260502105008.21827-1-jhapavitra98@gmail.com>) which
proposes calling ntfs3_bad_de_range(); that helper does not
exist in mainline.  This patch uses inline checks.

Subject: [PATCH 3218/5214] ntfs3: cap RESTART_TABLE free-chain walker at
 rt->used

A crafted NTFS3 disk image triggers an in-kernel infinite loop at
mount time, hanging the mounting thread and firing the soft-lockup
watchdog within ~22s on multi-CPU hosts (panic with
kernel.softlockup_panic=1).  The bug is reachable from desktop USB
auto-mount on distributions where udisks2 routes the NTFS signature
to the in-tree ntfs3 driver (Arch family and an increasing fraction
of Fedora / openSUSE / RHEL deployments); CAP_SYS_ADMIN-class manual
mount elsewhere.

check_rstbl()'s second walker iterates the free-entry singly-linked
list headed by rt->first_free with no upper bound on iteration count:

  for (off = ff; off;) {
      if (off == RESTART_ENTRY_ALLOCATED)
          return false;
      off = le32_to_cpu(*(__le32 *)Add2Ptr(rt, off));
      if (off > ts - sizeof(__le32))
          return false;
  }

The existing guards cover three exits: end-of-list (off == 0), the
in-use marker (off == RESTART_ENTRY_ALLOCATED), and out-of-bounds
(off > ts - sizeof(__le32)).  None of the three prevents an
in-bounds cycle.

A crafted on-disk RESTART_TABLE whose free chain contains a
self-loop or A->B->A cycle whose offsets satisfy:

  - in range [sizeof(struct RESTART_TABLE), ts - sizeof(__le32)]
  - (off - sizeof(struct RESTART_TABLE)) % rsize == 0

passes all existing guards and spins the mount-time thread forever.
Reproduced in UML by hand-forging a 2 MB NTFS3 image whose journal
RESTART_TABLE first_free = 0x18 and whose entry at offset 0x18
stores 0x18 as its next pointer; mount of the forged image with
the in-tree ntfs3 driver never returns.

Bound the walker by rt->used.  Each entry on a legitimate free
chain is unique, and the total slot count is ne = le16_to_cpu
(rt->used).  A traversal that visits more than ne slots is by
construction malformed; reject it as a corrupt RESTART_TABLE.

After this patch, mount of the forged image returns with -EINVAL
and a log_replay failure message, and mkntfs-produced legitimate
images mount cleanly (verified in the same UML harness).

Subject: [PATCH 3219/5214] platform/x86: hp-wmi: Add support for Omen
 16-ap0xxx (8E35)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The HP Omen 16-ap0xxx (board ID: 8E35) has the same WMI interface as
other Victus S boards, but requires quirks for correctly switching
thermal profile.

Add the DMI board name to victus_s_thermal_profile_boards[] table and
map it to omen_v1_legacy_thermal_params.

Testing on board 8E35 confirmed that platform profile is registered
successfully and fan RPMs are readable and controllable.

Subject: [PATCH 3222/5214] ntfs: reject non-resident records for resident-only
 attributes

The shared lookup-time attribute validator rejects non-resident
$FILE_NAME and $VOLUME_NAME records because their formats require
resident values and callers handle returned records as resident
attributes. Other resident-only attribute types still pass through the
generic non-resident mapping-pairs checks.

That leaves real resident/non-resident union confusion paths. Inode load
looks up $STANDARD_INFORMATION and then reads data.resident.value_offset
without checking a->non_resident. ntfs_inode_sync_standard_information()
does the same when updating the standard information value.
ntfs_write_volume_flags() also looks up $VOLUME_INFORMATION and reads
data.resident.value_offset directly. $INDEX_ROOT callers in dir.c and
index.c depend on the same lookup contract before consuming the resident
index root value.

Reject non-resident records for all resident-only attribute types in the
shared validator. Keep the existing $FILE_NAME and $VOLUME_NAME behavior,
but factor it through a helper and extend it to
$STANDARD_INFORMATION, $OBJECT_ID, $VOLUME_INFORMATION, $INDEX_ROOT, and
$EA_INFORMATION. For $OBJECT_ID and $EA_INFORMATION this is contract
hardening for resident-only formats; this patch only rejects the
non-resident form and does not add new resident value validation for
those types.

Subject: [PATCH 3223/5214] ntfs: grow index root value before reparent header
 update

ntfs_ir_reparent() moves the resident index root entries into an index
block and leaves a small root stub containing the child VCN. That root
stub can be larger than the existing resident value. For example, an
empty root with value_length 48 has an index area of 32 bytes, while the
large-index root stub needs index_length and allocated_size of 40 bytes.

The current code publishes the larger index.index_length and
index.allocated_size before resizing the resident value. If the resize
returns -ENOSPC, the recovery path can call ntfs_inode_add_attrlist(),
which looks attributes up again while the root header says
allocated_size 40 but the resident value still only provides 32 bytes of
index area. Lookup-time $INDEX_ROOT validation then correctly rejects
that transient layout as corrupt.

This reproduces as a generic/013 failure under qemu. In the failing run,
the transient root had value_len=48, index_size=32, index_length=40, and
allocated_size=40, and ntfsprogs-plus ntfsck reported "Corrupt index
root in MFT record 1177".

When the root stub grows, resize the resident value before publishing the
larger root header. If the resize fails, the old root remains valid for
recovery lookups. Keep the existing header-before-resize ordering for
shrink or same-size cases so the resident value never temporarily
exposes an allocated_size beyond its bounds.

Subject: [PATCH 3224/5214] ntfs: update index root allocated size before
 shrink

ntfs_ir_truncate() currently shrinks the resident $INDEX_ROOT value first
and only updates index.allocated_size after re-looking up the attribute.
During that relookup, the resident value_length can already be smaller
while index.allocated_size still contains the old larger size.

That leaves a transiently inconsistent $INDEX_ROOT layout and prevents
lookup-time $INDEX_ROOT validation from being enabled: validation can
correctly reject allocated_size extending past the newly shrunk resident
value.

When shrinking, lower index.allocated_size before shrinking value_length.
If the truncate fails, restore the old allocated_size. Keep the existing
grow ordering because the old allocated_size remains within the enlarged
resident value until it is updated after the relookup. The shrink path is
safe because the new value_length still covers struct index_root, so the
index.allocated_size field remains present while it is updated first.

Subject: [PATCH 3225/5214] ntfs: validate resident index root values on lookup

Resident $INDEX_ROOT values carry index header fields that callers
consume after lookup. Some callers already validate parts of the layout
before walking entries, but those checks are scattered and do not cover
all root header invariants, such as entries_offset alignment and lower
bound, index_length, and allocated_size consistency.

The resident root resize paths now keep these header fields consistent
while the value size changes: ntfs_ir_truncate() lowers
index.allocated_size before shrinking the resident value, and
ntfs_ir_reparent() grows the resident value before publishing a larger
root header. Lookup-time validation can therefore cover these invariants
without tripping over the driver's own resize paths.

Add $INDEX_ROOT to the minimum resident value size table and validate the
resident index header fields before returning the attribute from lookup.
Require 8-byte aligned index header fields, a sane entries_offset, an
index_length within allocated_size, allocated_size within the resident
value, and enough entry space for at least an index entry header.

The shared validator already rejects non-resident records for
resident-only attribute types, including $INDEX_ROOT.

Subject: [PATCH 3226/5214] ntfs: use direct pointer for inline data to avoid
 redundant allocation

Previously, NTFS used page allocation for IOMAP_INLINE to ensure that
the inline_data pointer was page-aligned, avoiding strict boundary checks
in the iomap core. Since the previous patch has removed the over-strict
PAGE_SIZE boundary check in iomap, NTFS can now safely point
iomap::inline_data directly to the MFT record.
This change eliminates redundant memory allocations and memcpy operations
in both read and write paths. It also simplifies the iomap_ops by removing
the need for a iomap_end callback that was previously used to free
the temporary page.

 PCIE_FTS_NUM_L0 macro
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The original PCIE_FTS_NUM_L0(x) macro was buggy due to improper operator
precedence, where ((x) & 0xff << 8) was evaluated as ((x) & 0xff00).

Instead of just fixing the parentheses, use the standard FIELD_PREP()
macro. This makes the code more robust by automatically handling masks
and shifts, while also adding compile-time type and range checking to
ensure the value fits within PCIE_FTS_NUM_MASK.

Subject: [PATCH 3230/5214] PCI: Add common TLP type macros and convert
 aspeed/mediatek

Introduce a set of unified TLP type macros in pci.h according to PCIe
spec r7.0, sec 2.2.1:

  - PCIE_TLP_TYPE_MEM_RDWR   (0x00) for Memory Read/Write
  - PCIE_TLP_TYPE_IO_RDWR    (0x02) for I/O Read/Write
  - PCIE_TLP_TYPE_CFG0_RDWR  (0x04) for Type 0 Config Read/Write
  - PCIE_TLP_TYPE_CFG1_RDWR  (0x05) for Type 1 Config Read/Write
  - PCIE_TLP_TYPE_MSG        (0x10) for Message Request (routing to RC)

These replace the old per-driver hardcoded values or local macros, and
also replace the previous PCIE_TLP_TYPE_CFG0_RD/WR and
PCIE_TLP_TYPE_CFG1_RD/WR definitions which had identical numeric values.
The read/write distinction is already handled by the TLP Format field
(Fmt), so a single type macro suffices.

Convert the aspeed and mediatek drivers to use the new macros, and remove
the obsolete definitions from pci.h.

No functional change intended.

Subject: [PATCH 3231/5214] PCI: dwc: Replace ATU type macros with common TLP
 type macros

The dwc driver defines its own ATU type macros (PCIE_ATU_TYPE_MEM,
PCIE_ATU_TYPE_IO, PCIE_ATU_TYPE_CFG0, PCIE_ATU_TYPE_CFG1,
PCIE_ATU_TYPE_MSG) with the same numerical values as the newly
introduced common TLP type macros.

Remove the local definitions and switch all DWC users to the common
PCIE_TLP_TYPE_* macros. This eliminates redundancy and improves
consistency across PCI controller drivers.

No functional change intended.

Subject: [PATCH 3233/5214] PCI: Avoid FLR for MediaTek MT7925 WiFi

The MediaTek MT7925 WiFi device advertises FLR capability, but it does not
work correctly. This manifests in VFIO passthrough scenarios. Normal VM
operation works fine, including clean shutdown/reboot. However, when the VM
terminates uncleanly (crash, force-off), VFIO attempts to reset the device
before it can be assigned to another VM. Because FLR is broken, the reset
fails, preventing reuse.

This is similar to its predecessor MT7922 (see 81f64e925c29 ("PCI: Avoid
FLR for Mediatek MT7922 WiFi")), but with different symptoms.  The MT7922
issue manifests as config read failures (returning ~0) after FLR. The
MT7925 shows different behavior: config reads work correctly after FLR, but
firmware communication fails.

First VM start with MT7925 works fine:

  mt7925e 0000:08:00.0: ASIC revision: 79250000
  mt7925e 0000:08:00.0: WM Firmware Version: ____000000, Build Time: 20260106153120

After force reset or VM crash, when VFIO attempts FLR to reset the device
for reassignment, firmware initialization fails:

  mt7925e 0000:08:00.0: ASIC revision: 79250000
  mt7925e 0000:08:00.0: Message 00000010 (seq 1) timeout
  mt7925e 0000:08:00.0: Failed to get patch semaphore
  [Repeats with increasing sequence numbers 2-10]
  mt7925e 0000:08:00.0: hardware init failed

The driver cannot acquire the patch semaphore needed for firmware
initialization, indicating that FLR does not properly reset the firmware
state. The device remains in this broken state until physical power cycle.

Disable FLR for MT7925 so the PCI core falls back to other reset methods,
e.g., Secondary Bus Reset, which successfully resets the device and allows
reinitialization for VFIO passthrough reuse.

Subject: [PATCH 3234/5214] PCI: Add pci_host_common_link_train_delay() helper

PCIe r6.0, sec 6.6.1 (Conventional Reset) requires that for a Downstream
Port supporting Link speeds greater than 5.0 GT/s, software must wait a
minimum of 100 ms after Link training completes before sending any
Configuration Request.

Introduce a static inline helper pci_host_common_link_train_delay() that
checks the given max_link_speed (2 = 5.0 GT/s, 3 = 8.0 GT/s, etc.) and
calls msleep(100) only when the speed is greater than 5.0 GT/s.

This allows multiple host controller drivers to share the same mandatory
delay without duplicating the logic.

Subject: [PATCH 3235/5214] PCI: cadence: Add post-link delay for LGA and j721e
 glue driver

The Cadence LGA (Legacy Architecture IP) PCIe host controller currently
lacks the mandatory 100 ms delay after link training completes for speeds
> 5.0 GT/s, as required by PCIe r6.0 sec 6.6.1.

Add a 'max_link_speed' field to struct cdns_pcie. In the common host
layer function cdns_pcie_host_start_link(), after the link has been
successfully established, call pci_host_common_link_train_delay() to
insert the required delay.

For the j721e glue driver, set cdns_pcie.max_link_speed from the existing
link speed logic. For other LGA-based glue drivers (sky1, sg2042), the
common LGA host setup (pcie-cadence-host.c) provides a fallback reading
of the device tree property "max-link-speed" when available. This ensures
that the delay is not missed on those platforms once they enable the

 hugepages

Add the hpage_2g module parameter to KVM to allow enabling or disabling
2G hugepages in KVM.

If hpage_2g is enabled but hpage is not enabled, print a message and
disable hpage_2g.

Opportunistically fix the comment for the hpage module parameter.

Subject: [PATCH 3240/5214] PCI: imx6: Configure REF_USE_PAD before PHY reset
 for i.MX95

According to the i.MX95 PCIe PHY Databook, the ref_use_pad signal in the
Common Block Signals section selects the reference clock source connected
to the PHY pads. Per the specification, any change to this input must be
followed by a PHY reset assertion to take effect.

Move the REF_USE_PAD configuration before the PHY reset toggle to comply
with the required initialization sequence.

Subject: [PATCH 3241/5214] PCI: imx6: Assert ref_clk_en after reference clock
 stabilizes on i.MX95

According to the PHY Databook Common Block Signals section, the
ref_clk_en signal must remain de-asserted until the reference clock is
running at the appropriate frequency. Once the clock is stable,
ref_clk_en can be asserted. For lower power states where the reference
clock to the PHY is disabled, ref_clk_en should also be de-asserted.

Move the ref_clk_en bit manipulation into imx95_pcie_enable_ref_clk()
to ensure the reference clock stabilizes before ref_clk_en is asserted
and before the PHY reset is de-asserted. This aligns with the timing
requirements specified in the PHY documentation.

 failure

meson_pcie_probe_clock() enables a clock and then registers a devres
action to disable it during teardown. If devm_add_action_or_reset()
fails, it runs the action immediately, disabling the clock.

The return value is currently ignored, so on that failure path,
meson_pcie_probe_clock() returns the disabled clock and probe continues.
Return the error so the existing probe error path unwinds normally.

Subject: [PATCH 3243/5214] PCI: meson: Add missing remove callback

meson_pcie_probe() powers on the PHY and registers the DesignWare host
bridge with dw_pcie_host_init(), but the driver has no remove callback.
On driver unbind or module unload, the driver core therefore proceeds to
devres cleanup without first unregistering the host bridge or powering off
the PHY.

Add a remove callback that deinitializes the DesignWare host bridge and
powers off the PHY while device-managed resources are still valid.

Subject: [PATCH 3244/5214] nvmet: fix refcount leak in nvmet_sq_create()

In nvmet_sq_create(), a reference on the ctrl is taken
via kref_get_unless_zero() before calling nvmet_check_sqid().
If nvmet_check_sqid() fails, the function returns the error
directly without releasing the reference, leading to a leak.

Fix this by jumping to the "ctrl_put" label, which already
performs the necessary nvmet_ctrl_put(ctrl). This ensures the
reference is properly released on this error path.

Subject: [PATCH 3245/5214] cxl: Fix CXL_HEADERLOG_SIZE to match RAS Capability
 size

The CXL r4.0 8.2.4.17.7 RAS Capability Structure has total length 0x58
bytes (CXL_RAS_CAPABILITY_LENGTH); the Header Log occupies the trailing
64 bytes at offset 0x18.  CXL_HEADERLOG_SIZE was defined as SZ_512,
eight times the actual on-device size.

header_log_copy() reads CXL_HEADERLOG_SIZE_U32 (128) dwords from the
RAS capability iomap, overrunning the 88-byte mapping by 448 bytes.
The cxl_aer_uncorrectable_error trace event memcpy()s CXL_HEADERLOG_SIZE
(512) bytes from its source.  For the CPER caller the source is
struct cxl_ras_capability_regs::header_log[16] (64 bytes) embedded in a
stack-local cxl_cper_prot_err_work_data, so the memcpy reads 448 bytes
of kernel stack into the trace event ring buffer where userspace can
read it via tracefs.

Set CXL_HEADERLOG_SIZE to 64 and derive CXL_HEADERLOG_SIZE_U32 from it,
bringing all iomap readers into agreement on 16 dwords.  Userspace tools
such as rasdaemon have grown a dependency on the buggy 512-byte (128 u32)
header_log layout in the cxl_aer_uncorrectable_error trace event.  Add
CXL_HEADERLOG_TRACE_SIZE_U32 = 128 and use it for the trace event
__array and its memcpy to preserve that ABI.  Both callers now pass a
zero-filled u32[CXL_HEADERLOG_TRACE_SIZE_U32] staging buffer with only
the first CXL_HEADERLOG_SIZE_U32 (16) entries populated from hardware;
the remaining 112 u32s are zero-padded, keeping the 512-byte trace ring
buffer layout intact.

Subject: [PATCH 3246/5214] PCI: mediatek: Fix IRQ domain leak when port fails
 to enable

When mtk_pcie_enable_port() fails, mtk_pcie_port_free() removes the port
from pcie->ports and frees the port structure. However, the IRQ domains set
up earlier by mtk_pcie_init_irq_domain() are never freed.

Fix this by refactoring mtk_pcie_irq_teardown() into a per-port helper,
mtk_pcie_irq_teardown_port(), and calling it from mtk_pcie_setup() when
mtk_pcie_enable_port() fails. Since the IRQ teardown must only happen in
the probe error path (during resume, child devices may have active MSI
mappings and the NOIRQ context prohibits sleeping locks),
mtk_pcie_enable_port() is changed to return an error code so callers can
distinguish the two paths and act accordingly.

This issue was reported by Sashiko while reviewing the EcoNet EN7528 SoC
support series.

Subject: [PATCH 3247/5214] nvme: fix crash and memory leak during invalid cdev
 teardown

In the NVMe multipath code, if nvme_add_ns_head_cdev() fails during
nvme_mpath_set_live(), the error is ignored. However, during teardown,
nvme_remove_head() unconditionally calls nvme_cdev_del(). This teardown
asymmetry leads to a kernel panic if the character device was never
successfully initialized.

BUG: kernel NULL pointer dereference, address: 00000000000000d0
 device_del+0x39/0x3c0
 cdev_device_del+0x15/0x50
 nvme_cdev_del+0xe/0x20 [nvme_core]
 nvme_mpath_shutdown_disk+0x38/0x60 [nvme_core]
 nvme_ns_remove+0x177/0x1f0 [nvme_core]
 nvme_remove_namespaces+0xdc/0x130 [nvme_core]
 nvme_do_delete_ctrl+0x71/0xd0 [nvme_core]

Additionally, a memory leak exists in the nvme_cdev_add() failure path.
Previously, dev_set_name() was called before ida_alloc(). If ida_alloc()
subsequently failed, device_initialize() was never called, meaning
put_device() could not be used to clean up the kobject, leaking the
memory allocated by dev_set_name().

*  Introduces the NVME_NSHEAD_CDEV_LIVE and NVME_NS_CDEV_LIVE bits to track
   the successful creation of the character devices. Teardown routines now
   check these bits before attempting deletion.
*  Refactor nvme_cdev_add() to accept the formatted device name as a
   parameter, moving dev_set_name() after the IDA allocation and
   immediately before device_initialize(). This ensures any internally
   allocated strings are safely cleaned up by put_device() upon failure.

Subject: [PATCH 3248/5214] cxl/region: Avoid variable shadowing in region
 attach paths

A couple of symbol declarations shadow earlier variables in the region
attach paths. Shadowing makes it harder to tell which object is being
referenced and can obscure future bugs.

Reuse the existing 'cxld' variable in cxl_port_attach_region() and
rename the endpoint decoder iterator in cxl_region_attach() to avoid
shadowing the function parameter.

No functional change.

Found with sparse.

Subject: [PATCH 3251/5214] nvmet-rdma: handle inline data with a nonzero
 offset

nvmet_rdma_use_inline_sg() maps the host-controlled inline data offset
into the per-command inline scatterlist.  The bounds check admits any
offset with off + len <= inline_data_size, but the mapping still assumes
the data begins in the first inline page:

	sg->offset = off;
	sg->length = min_t(int, len, PAGE_SIZE - off);

When a port is configured with inline_data_size > PAGE_SIZE (settable up
to max(SZ_16K, PAGE_SIZE)), an offset in (PAGE_SIZE, inline_data_size]
makes "PAGE_SIZE - off" underflow, so sg->length is set to ~4 GiB and
the block backend reads far past the first inline page.  num_pages(len)
also ignores the offset, so an in-bounds offset whose [off, off+len)
span crosses a page boundary under-counts the scatterlist.

Map the offset properly: split it into a page index and an in-page
offset, start the scatterlist at that page, and size the page count from
page_off + len.  Because the request scatterlist may now start at
inline_sg[page_idx] rather than inline_sg[0], generalize the inline-SGL
identity test in nvmet_rdma_release_rsp() to a range test; otherwise the
persistent inline scatterlist is mistaken for an allocated one and
nvmet_req_free_sgls() frees an inline page (and warns in
free_large_kmalloc()).

Fixes: 0d5ee2b2ab4f ("nvmet-rdma: support max(16KB, PAGE_SIZE) inline data")

Subject: [PATCH 3252/5214] PCI/P2PDMA: Add Intel QAT, DSA, IAA devices to
 whitelist

The first device on a PCI root bus determines whether the host bridge is
whitelisted for P2PDMA.  All Intel Xeon chips since Ice Lake (ICX, 2021)
expose a device with ID 0x09a2 as first device.  It is loosely associated
with the IOMMU.  All these Xeon chips support P2PDMA, so since the addition
of the device with commit feaea1fe8b36 ("PCI/P2PDMA: Add Intel 3rd Gen
Intel Xeon Scalable Processors to whitelist"), P2PDMA has been allowed on
all new Xeons without the need to amend the whitelist:

Xeons with Performance Cores:
  Sapphire Rapids (SPR, 2023)
  Emerald Rapids (EMR, 2023)
  Granite Rapids (GNR, 2024)
  Diamond Rapids (DMR, 2026)

Xeons with Efficiency Cores:
  Sierra Forest (SRF, 2024)
  Clearwater Forest (CWF, 2026)

However these Xeons also expose accelerators as first device on a root bus
of its own:

  QuickAssist Technology (QAT, crypto & compression accelerator)
  Data Streaming Accelerator (DSA, dma engine)
  In-Memory Analytics Accelerator (IAA, compression accelerator)

Whitelist them for P2PDMA as well.  Move their Device ID macros from the
accelerator drivers to <linux/pci_ids.h> for reuse by P2PDMA code.

Unfortunately the Device IDs vary across Xeon generations as additional
features were added to the accelerators.  This currently necessitates an
amendment for each new Xeon chip.

For future chips, this need shall be avoided by an ongoing effort to extend
ACPI HMAT with PCIe P2PDMA characteristics (latency, bandwidth, ordering
constraints).  The PCI core will be able look up in this BIOS-provided ACPI
table whether P2PDMA is supported, instead of relying on a whitelist that
needs to be amended continuously.

Subject: [PATCH 3254/5214] fs/ntfs3: prevent potential lcn remains
 uninitialized

The target VCN being sought was not found within runs[0], causing
run_lookup() to return false. This causes run_lookup_entry() to return
false, which in turn results in a len value of 0, and the new parameter
passed to attr_data_get_block() is NULL. Collectively, these factors
ultimately cause attr_data_get_block_locked() to exit prematurely without
initializing lcn, thereby triggering [1].

To prevent [1], the clen check within ni_seek_data_or_hole() has been
moved to occur before the lcn check.

Subject: [PATCH 3255/5214] fs/ntfs3: resize log->one_page_buf when adopting
 on-disk page size

log_replay() allocates log->one_page_buf using the page size that was
chosen from the host PAGE_SIZE:

	log->one_page_buf = kmalloc(log->page_size, GFP_NOFS);

Later, when a restart area is found, the log page size recorded on disk
is adopted:

	t32 = le32_to_cpu(log->rst_info.r_page->sys_page_size);
	if (log->page_size != t32) {
		log->l_size = log->orig_file_size;
		log->page_size = norm_file_page(t32, &log->l_size,
						t32 == DefaultLogPageSize);
	}

If the on-disk page size is larger than the size used for the initial
allocation, log->page_size grows but one_page_buf is left at its
original, smaller size. A subsequent unaligned read_log_page() then
reads log->page_size bytes into the undersized scratch buffer:

	page_buf = page_off ? log->one_page_buf : *buffer;
	err = ntfs_read_run_nb_ra(ni->mi.sbi, &ni->file.run, page_vbo, page_buf,
				  log->page_size, NULL, &log->read_ahead);

overflowing the allocation. This is reachable when mounting a dirty
NTFS volume whose log was formatted with a page size larger than the
buffer initially allocated on the mounting host (for example a 64K-log
volume mounted on a host that allocated a 4K scratch buffer).

Grow one_page_buf when the adopted on-disk page size exceeds the size
used for the initial allocation. On krealloc() failure the original
buffer is left intact and freed by the existing error path.

Subject: [PATCH 3256/5214] ntfs3: reject direct userspace writes to reserved
 $LX* xattrs

NTFS3 uses $LXUID, $LXGID, $LXMOD and $LXDEV as internal WSL
permission metadata and reloads them into i_uid, i_gid and i_mode
from ntfs_get_wsl_perm().

Because the empty-prefix xattr handler also lets file owners call
setxattr() on these names directly, an unprivileged writer on a
writable ntfs3 mount can plant root ownership and S_ISUID on their own
file and gain euid 0 after inode reload.

Reject direct userspace writes to the reserved $LX* names. Internal
ntfs3 metadata updates are unchanged because ntfs_save_wsl_perm()
writes them via ntfs_set_ea() directly.

Subject: [PATCH 3257/5214] KVM: arm64: nv: Avoid dereferencing NULL VNCR
 pseudo-TLB

VNCR TLB invalidation occurs from MMU notifiers or TLBI instructions,
and either can race against a vcpu not being onlined yet (no pseudo-TLB
allocated). Similarly, the TLB might be invalid, and the invalidation
should be skipped in this case.

Both kvm_invalidate_vncr_ipa() and kvm_invalidate_vncr_va() are
expected to perform the same checks, except that the latter doesn't
check for the allocation and blindly dereferences the pointer.

Solve this by introducing a new iterator built on top of the usual
kvm_for_each_vcpu() that checks for both of the above conditions,
and convert the two users to it.

Subject: [PATCH 3258/5214] platform/x86: intel-hid: Add HP ProBook x360 440 G1
 to button_array_table
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The volume rocker buttons on the HP ProBook x360 440 G1 convertible emit
events 0xc4-0xc7 via the intel-hid ACPI device (INT33D5). These codes are
only present in intel_array_keymap, which is used when the "5 button
array" input device exists. On this machine button_array_present()
returns false because the firmware does not advertise the array through
the HEBC method, so notify_handler() routes the events to a NULL
priv->array and they are dropped as "unknown event 0xc4". As a result
the side volume keys do nothing.

Add the machine to button_array_table so the array device is created and
the volume rocker emits KEY_VOLUMEUP / KEY_VOLUMEDOWN. This is equivalent
to booting with the enable_5_button_array=1 module parameter, which was
used to confirm the fix on the affected hardware.

Subject: [PATCH 3259/5214] platform/x86/amd/pmc: Use per-SoC cpu_info struct
 for SMU mailbox and IP info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the scattered per-field assignments in amd_pmc_get_ip_info() with
a single amd_pmc_cpu_info struct capturing all SoC-specific parameters
such as SMU offsets, IP block table, and OS hint.

Define static const instances per SoC variant and embed them as driver_data
in the PCI ID table via PCI_DEVICE_DATA(). Consolidate pci_match_id() into
amd_pmc_set_cpu_info(), which assigns driver_data directly to cpu_info,
the switch falls through only for 1Ah M20H/M60H variants requiring
boot_cpu_data.x86_model detection to distinguish the M70 sub-variant.

Add scratch_reg to amd_pmc_cpu_info and populate it for each SoC
variant, allowing amd_pmc_idlemask_read() to drop its cpu_id switch
in favour of a single cpu_info->scratch_reg lookup.

Move dev->cpu_id assignment into amd_pmc_set_cpu_info() so it is valid
before the switch statement. Handle SP/SHP directly in the switch since
their NULL driver_data bypasses the early return, and remove the duplicate
check from probe.

Remove amd_pmc_get_os_hint() and use cpu_info->os_hint directly at call
sites and rename AMD_CPU_ID_* to PCI_DEVICE_ID_AMD_CPU_ID_* with backward
compatibility aliases.

Subject: [PATCH 3260/5214] platform/x86/amd/pmc: Add PMC driver support for
 AMD 1Ah M80H SoC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 1Ah M80H SoC uses a different set of SMU mailbox register offsets
compared to the existing 1Ah variants: message at 0xA10, argument at
0xA18, and response at 0xA14.

Add amd_1ah_m80_cpu_info with these offsets, wire it into the PCI ID
table via PCI_DEVICE_DATA(), populate scratch_reg field with
AMD_PMC_SCRATCH_REG_1AH and add the corresponding ACPI ID AMDI000C.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

dell_init() initializes several resources after dell_setup_rfkill(),
including the optional touchpad LED, keyboard backlight LED, battery
hook, debugfs directory and dell-laptop notifier.

If a later LED or backlight registration fails, the error path only
tears down the battery hook and rfkill resources. This leaves the
notifier, debugfs directory, keyboard backlight LED and optional
touchpad LED registered after dell_init() returns an error.

Add the missing cleanup calls before tearing down rfkill.

Subject: [PATCH 3262/5214] platform/x86/intel/vsec: Restore BAR fallback for
 header walk
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The base_addr refactor changed intel_vsec_walk_header() to pass
info->base_addr as the discovery-table base address. For the PCI VSEC
driver this info comes from driver_data, but exported callers may provide
their own static headers and leave base_addr unset.

For xe, this made the discovery-table base address zero instead of the BAR
selected by header->tbir, preventing PMT endpoints from being created.

Restore the previous behavior for the header-walk path by falling back to
pci_resource_start(pdev, header->tbir) when base_addr is not specified.
Keep explicit base_addr override behavior unchanged.

This preserves the refactor structure while fixing the functional
regression in manual-header users.

Subject: [PATCH 3263/5214] platform/x86: intel-hid: Protect ACPI notify
 handler against recursion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since commit e2ffcda16290 ("ACPI: OSL: Allow Notify () handlers to run on
all CPUs") ACPI notify handlers like the intel-hid notify_handler() may
run on multiple CPU cores racing with themselves.

On convertibles and detachables (matched by DMI chassis-type 31 and 32 in
dmi_auto_add_switch[]) the SW_TABLET_MODE input device is registered
lazily from notify_handler() on the first tablet-mode event, via
intel_hid_switches_setup(). When two such events race on different CPUs
both can pass the !priv->switches check and register the priv->switches
input device twice, resulting in a duplicate sysfs entry and a subsequent
NULL pointer dereference.

This is the same class of bug fixed by commit e075c3b13a0a ("platform/x86:
intel-vbtn: Protect ACPI notify handler against recursion") for the
sibling intel-vbtn driver.

Protect intel-hid notify_handler() from racing with itself with a mutex
to fix this.

 current_freq_khz after CPU hotplug
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the last CPU of a legacy uncore die goes offline,
uncore_freq_remove_die_entry() clears control_cpu. During CPU hotplug
re-add, uncore_freq_add_entry() still populates sysfs attributes before
assigning the new control CPU. As a result, the current frequency read
returns -ENXIO and current_freq_khz is omitted from the recreated sysfs
group.

Assign control_cpu before the initial read paths and before
create_attr_group() so sysfs recreation uses the new online CPU. If
sysfs creation fails, restore control_cpu to -1 to keep the error path
state consistent.

Subject: [PATCH 3265/5214] KVM: arm64: nv: Hold kvm->mmu_lock while
 initialising vcpu->arch.vncr_tlb

Sashiko reports that there is a race between initialising vncr_tlb
and making use of it, as we don't hold the mmu_lock at this point.

Additionally, it identifies a memory leak, should userspace repeatedly
invokes the KVM_RUN ioctl after a failure of kvm_arch_vcpu_run_pid_change(),
as we assign vncr_tlb blindly on first run, irrespective of prior
allocations.

Slap the two bugs in one go by taking the kvm->mmu_lock on assigning
vncr_tlb, preventing the race for good, and by checking that vncr_tlb
is indeed NULL prior to allocation.

Subject: [PATCH 3266/5214] platform/x86: ISST: Restore SST-PP control to all
 domains
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The SST-PP control offset is only restored to power domain 0 after
resume. During suspend, control values are read and stored for all
power domains.

Use pd_info->sst_base instead of power_domain_info->sst_base, which
only points to power domain 0 base address.

Integrate the PCI pwrctrl framework into the pci-imx6 driver to provide
standardized power management for PCI devices.

Legacy regulator handling (vpcie-supply at controller level) is maintained
for backward compatibility with existing device trees. New device trees
should specify power supplies at the Root Port level to utilize the pwrctrl
framework.

The return code from nvme_add_ns_head_cdev() and nvme_add_ns_cdev() is
never checked, so make those functions return void.

A cdev add failure is tolerated during initialization, and flags
NVME_NS_CDEV_LIVE and NVME_NSHEAD_CDEV_LIVE are for determining whether
a cdev needs to be deleted during un-initialization.

calling __nvme_fc_abort_outstanding_ios() which aborts requests in both
admin and io tagsets. In case fc_ctrl->tag_set was not initialized we
see the warning below. This is because ctrl.queue_count is initialized
early in nvme_fc_alloc_ctrl().

Subject: [PATCH 3271/5214] perf tools: Fix get_max_num() size_t underflow on
 empty sysfs file

get_max_num() reads a sysfs file (cpu/possible, cpu/present, or
node/possible) and scans backward from the end to find the last
number.  If the file is empty, filename__read_str() returns num == 0.
The loop `while (--num)` decrements the size_t from 0 to SIZE_MAX,
reading backward across the heap until a comma or hyphen is found
or unmapped memory is hit.

Add an early return for empty files before the backward scan.

Subject: [PATCH 3272/5214] perf tools: Use scnprintf() in cpu_map__snprint()
 to prevent overflow

cpu_map__snprint() accumulates snprintf() return values in ret.
snprintf() returns the number of characters that *would have been
written* on truncation, not the actual count.  When a fragmented CPU
list exceeds the buffer, ret grows past size, causing `size - ret` to
underflow (both are size_t), and subsequent snprintf() calls write
past the end of the caller's stack buffer.

Switch to scnprintf() which returns the actual number of characters
written, making ret accumulation safe by construction.

Subject: [PATCH 3273/5214] perf tools: Use perf_env__get_cpu_topology() in
 machine__resolve()

machine__resolve() accesses env->cpu[al->cpu].socket_id after checking
al->cpu >= 0 and env->cpu != NULL, but without validating al->cpu
against env->nr_cpus_avail.  Since al->cpu comes from the untrusted
perf.data sample, a crafted file with a large CPU index causes an
out-of-bounds heap read.

Use perf_env__get_cpu_topology() which validates both NULL and bounds.
Also bounds-check al->cpu before the cast to struct perf_cpu (int16_t):
without this, values like 65536 silently truncate to 0, bypassing the
accessor's internal check and returning CPU 0's topology.

Subject: [PATCH 3274/5214] nvmet-auth: reject short AUTH_RECEIVE buffers

nvmet_execute_auth_receive() trusts the AUTH_RECEIVE allocation length
after checking only that it is nonzero and matches the transfer length.
In the SUCCESS1 and FAILURE1/default states, that lets a remote NVMe-oF
initiator reach the fixed-size DH-HMAC-CHAP response builders with a
kmalloc() buffer shorter than the response, so nvmet_auth_success1() and
nvmet_auth_failure1() write past the allocation; both only WARN_ON the
short length and then format the message anyway.

Impact: A remote NVMe-oF initiator with access to an auth-enabled target
can trigger a 16-byte heap out-of-bounds write via a one-byte
AUTH_RECEIVE allocation length.

Compute the minimum response length for the current DH-HMAC-CHAP step in
nvmet_auth_receive_data_len() and report a zero data length when the
host-supplied allocation length is shorter, so the existing zero-length
check in nvmet_execute_auth_receive() rejects the command before any
builder runs. The SUCCESS1 minimum is sizeof(struct
nvmf_auth_dhchap_success1_data) plus the HMAC hash length, because the
response hash is written into the rval[] flexible-array tail, so the
minimum is state dependent rather than a flat sizeof. CHALLENGE keeps its
existing variable-length guard in nvmet_auth_challenge().

This is reachable only when in-band DH-HMAC-CHAP authentication is
configured on the target.

Subject: [PATCH 3275/5214] nvmet-tcp: handle TCP_CLOSING state in
 nvmet_tcp_state_change

When an NVMe/TCP connection shuts down, the underlying TCP socket can
enter the TCP_CLOSING state (state 11).  Currently, the
nvmet_tcp_state_change() callback does not explicitly handle this state,
which results in harmless but noisy kernel warnings:

nvmet_tcp: queue 2 unhandled state 11

Add TCP_CLOSING to the switch statement alongside TCP_FIN_WAIT2 and
TCP_LAST_ACK to silently ignore the state transition.

Explicitly assigning .driver_data in drivers that don't use this member

There is no changed semantic, not even a change in the compiled result.

A comment in drivers/cxl/port.c refers to CONFIG_PROVE_CXL_LOCKING,
which was removed in commit 38a34e10768c ("cxl: Drop
cxl_device_lock()"). That commit switched CXL subsystem locking to
custom lock classes, which can be validated via the standard
CONFIG_PROVE_LOCKING option. Update the comment to reflect this.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.

Subject: [PATCH 3280/5214] cxl/test: Verify cmd->size_in before accessing
 payload

Several mock mailbox handlers access input payload fields before
verifying that cmd->size_in is large enough for the corresponding
structure.

To ensure invalid commands are rejected before any payload data is
consumed, add missing size checks and move existing checks ahead of
the first payload field access.

Subject: [PATCH 3282/5214] cxl/test: Fix integer overflow in mock LSA bounds
 checks

Pre-existing issue discovered by sashiko-bot.

mock_get_lsa() and mock_set_lsa() validate the requested LSA range with
"offset + length > LSA_SIZE". Both offset and length are u32 and, in
mock_get_lsa(), both are taken directly from the user-supplied payload.
The addition is evaluated modulo 2^32, so a large offset combined with a
small length wraps around and passes the check.

Rewrite the checks to first bound offset, then compare length against the
remaining LSA size.

Subject: [PATCH 3284/5214] perf sched: Bounds-check prio before test_bit() in
 timehist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

timehist_skip_sample() reads prio from untrusted tracepoint data via
perf_sample__intval(sample, "prev_prio") without bounds validation.
A crafted perf.data with prev_prio >= MAX_PRIO (140) causes test_bit()
to read past the end of the prio_bitmap, which is only MAX_PRIO bits.

Add a prio >= 0 guard before the test_bit() call and skip out-of-range
values (>= MAX_PRIO) that can never match the user's filter set.

The original prio != -1 already let all negatives other than -1 through
(after an undefined-behavior bitmap read); the new prio >= 0 guard
preserves that pass-through behavior — negative means "no priority
info", so the event is shown unfiltered — while fixing the OOB.
Values >= MAX_PRIO are skipped because they cannot be represented in
the filter bitmap.

Subject: [PATCH 3285/5214] perf sched: Fix idle-hist callchain display using
 wrong rb_first variant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

timehist_print_idlehist_callchain() calls rb_first_cached() on
sorted_root, but the sort function (callchain_param.sort) populates it
via rb_insert_color() on the plain rb_root member — not the cached
variant.  This means rb_leftmost is never set, so rb_first_cached()
always returns NULL and the entire callchain summary is silently
dropped from --idle-hist output.

The original code in ba957ebb54893aca ("perf sched timehist: Show
callchains for idle stat") was correct — it used struct rb_root and
rb_first().  The bug was introduced when sorted_root was converted to
rb_root_cached without converting the sort insertion path to use
rb_insert_color_cached().

Use rb_first(&root->rb_root) to match how the tree was populated.

Subject: [PATCH 3286/5214] perf tools: Add O_CLOEXEC to open() calls in DSO
 and ELF code

open() calls in dso.c and symbol-elf.c omit O_CLOEXEC, which leaks
file descriptors to child processes spawned during symbol resolution
(e.g., addr2line, objdump).  This can exhaust the fd limit during
long profiling sessions or when processing many DSOs.

Add O_CLOEXEC to all open() calls in both files (12 call sites).

Subject: [PATCH 3287/5214] perf bpf: Use scnprintf() in snprintf_hex() and
 synthesize_bpf_prog_name()

Both functions accumulate formatted output via ret += snprintf(buf + ret,
size - ret, ...).  If the buffer is too small and snprintf() returns more
than the remaining space, ret exceeds size and the next 'size - ret'
underflows, causing snprintf() to write past the buffer end.

Switch to scnprintf() which returns the actual number of bytes written,
making the accumulation safe.

 hists__scnprintf_title() UID filter path

hists__scnprintf_title() accumulates formatted output into a buffer
using scnprintf() for all filter clauses except the UID filter, which
uses snprintf().  If the buffer fills up and snprintf() returns more
than the remaining space, printed exceeds size and the next 'size -

Switch the UID filter clause to scnprintf() to match the rest of the

Subject: [PATCH 3289/5214] perf tools: Use scnprintf() in build_id__snprintf()
 and hwmon read_events()

build_id__snprintf() and hwmon_pmu__read_events() accumulate formatted
output via snprintf(), which returns the would-have-been-written count
on truncation.  In build_id__snprintf(), this inflates the return
value beyond the buffer size.  In hwmon_pmu__read_events(), len
overshoots out_buf_len and the next 'out_buf_len - len' underflows.

Switch both to scnprintf() which returns actual bytes written.

In build_id__snprintf(), also tighten the loop guard from
'offs < bf_size' to 'offs + 1 < bf_size': since scnprintf() returns
at most size-1, offs never reaches bf_size, and the original condition
would spin doing zero-byte writes once the buffer fills.

Add a bullet point to the libperf ABI TODO explaining the code
simplification benefit of widening struct perf_cpu.cpu from int16_t
to int: the narrow type forces defensive truncation checks at every
boundary where wider CPU indices are narrowed, and values > 32767
silently wrap to negative numbers (two's complement), bypassing
bounds validation without them.

Subject: [PATCH 3292/5214] PCI: Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi,
 SDX62/SDX65 modems

Some Qualcomm PCIe devices (WCN6855/WCN7850 WiFi cards, SDX62/SDX65 modems)
do not properly support Secondary Bus Reset (SBR).

Testing confirms this is device-specific, not deployment-specific:
MediaTek MT7925e successfully uses bus reset through the same passive
M.2-to-PCIe adapters where Qualcomm devices fail, proving PERST# is
properly wired through the adapters.

Prevent use of Secondary Bus Reset for these devices.

Subject: [PATCH 3293/5214] xprtrdma: Convert send buffer free list to llist

rpcrdma_buffer_get() and rpcrdma_buffer_put() both take rb_lock to
pop/push from the rb_send_bufs free list. Under high I/O concurrency
(e.g., nconnect=N with small random writes), this spinlock is contended
between the request submission path and the transport completion path.

Replace the list_head with an llist_head. The put side uses
lockless llist_add(), which is safe for concurrent producers. The
get side retains the spinlock to satisfy the llist single-consumer
contract portably; submitters continue to serialize there. Completion
handlers returning buffers no longer contend on rb_lock, eliminating
contention on the return path.

rb_lock remains for the MR free list and the tracking lists used
during setup and teardown. rb_free_reps already uses llist_head, so
the llist idiom is established in this structure. The precedent is the
data structure, not the locking: rb_free_reps serializes its single
consumer through the re_receiving gate in rpcrdma_post_recvs, whereas
rb_send_bufs serializes its consumer with rb_lock. Both satisfy the
llist single-consumer contract.

Subject: [PATCH 3294/5214] xprtrdma: Fix ep kref imbalance on ADDR_CHANGE

rpcrdma_cm_event_handler() falls through to the disconnected: label
on RDMA_CM_EVENT_ADDR_CHANGE and calls rpcrdma_ep_put() with no
matching get when the event arrives before RDMA_CM_EVENT_ESTABLISHED.
The kref then underflows during connect teardown and
rpcrdma_xprt_disconnect() operates on a freed ep.

Reference counts across a normal connection lifecycle:

    rpcrdma_ep_create()             kref_init     ->1
    rpcrdma_xprt_connect()          ep_get        ->2  (before post_recvs)
    RDMA_CM_EVENT_ESTABLISHED       ep_get        ->3
    RDMA_CM_EVENT_DISCONNECTED      ep_put        ->2
    rpcrdma_xprt_drain()            ep_put        ->1
    rpcrdma_xprt_disconnect() tail  ep_put        ->0  (ep_destroy)

The connect-time get in rpcrdma_xprt_connect(), taken just before
rpcrdma_post_recvs() "while there are outstanding Receives," is
balanced by rpcrdma_xprt_drain. ADDR_CHANGE before ESTABLISHED has
no get to consume, so its put drops the count to 1 and the drain
put then frees the ep while rpcrdma_xprt_disconnect() still holds a
pointer to it.

Fix by dispatching on the prior re_connect_status via xchg(): for
prev == 0 (pre-ESTABLISHED) wake the connect waiter and return with
no put; for prev == 1 call rpcrdma_force_disconnect() and return.
The case-1 arm relies on the subsequent RDMA_CM_EVENT_DISCONNECTED
event -- reliably delivered when rdma_disconnect() is called on a
still-connected cm_id -- to balance the ESTABLISHED get;
rpcrdma_xprt_drain() continues to balance only that connect-time
get. Any other prior value means teardown is already in flight.

Subject: [PATCH 3295/5214] xprtrdma: Initialize re_id before removal
 registration

rpcrdma_create_id() registers ep->re_rn with the rpcrdma ib_client
before returning the new rdma_cm_id to rpcrdma_ep_create(). However
rpcrdma_ep_create() currently stores that pointer in ep->re_id only
after rpcrdma_create_id() returns.

A local administrator can race an NFS/RDMA mount against RDMA device
removal. If rpcrdma_remove_one() observes the just-registered
notification before rpcrdma_ep_create() assigns ep->re_id,
rpcrdma_ep_removal_done() calls trace_xprtrdma_device_removal(NULL).
The tracepoint dereferences id->device->name and copies
id->route.addr.dst_addr, so the callback can crash the kernel with a
NULL pointer dereference.

Store the rdma_cm_id in ep->re_id immediately before publishing
ep->re_rn. The existing error path still destroys the id directly if
registration fails; ep is then freed by the caller without using
ep->re_id. Remove the later duplicate assignment in rpcrdma_ep_create().

Subject: [PATCH 3296/5214] xprtrdma: Check frwr_wp_create() during connect

frwr_wp_create() creates the singleton Memory Region used to encode
padding for Write chunks whose payload length is not XDR-aligned. Its
failure paths return a negative errno and leave ep->re_write_pad_mr set
to NULL.

rpcrdma_xprt_connect() currently ignores that return value. If
frwr_wp_create() fails after the rest of the connection setup succeeds,
xprt_rdma_connect_worker() treats the connection attempt as successful
and sets XPRT_CONNECTED. A later NFS/RDMA read with a non-4-byte-aligned
receive page length reaches rpcrdma_encode_write_list(), passes the NULL
write-pad MR to encode_rdma_segment(), and dereferences it.

This is locally triggerable on an NFS/RDMA client after a connect or
reconnect hits a local MR allocation, DMA-map, MR-map, or post-send
failure; a remote peer alone cannot force the local MR setup failure.

Check the return value and fail the connect as -ENOTCONN, matching the
adjacent setup failures. This keeps XPRT_CONNECTED clear and lets the
normal reconnect path retry.

Subject: [PATCH 3297/5214] xprtrdma: Resize reply buffers before reposting
 receives

Commit 0e13dd9ea8be ("xprtrdma: Remove temp allocation of
rpcrdma_rep objects") made rpcrdma_rep objects survive disconnects.
That is normally fine, but it also means their receive regbufs keep
the size they had when they were first allocated.

Each rep's receive buffer is sized to ep->re_inline_recv when the rep
is created. rpcrdma_ep_create() resets that threshold to the
rdma_max_inline_read ceiling for every new endpoint, and the connect
handshake then shrinks it to the peer's advertised inline send size.
A rep allocated under a smaller negotiated threshold keeps that size:
on disconnect, rpcrdma_xprt_disconnect() drains and DMA-unmaps the
surviving reps but does not free or resize them.

The threshold can come back larger on the next connection. The first
peer may supply no RPC-over-RDMA CM private data, defaulting its send
size to 1024, while the reconnect target is an ordinary server
offering 4096; or, with rdma_max_inline_read raised above its default,
the reconnect target may advertise a larger svcrdma_max_req_size than
the first. rpcrdma_post_recvs() then reposts a surviving rep whose SGE
length is still the old, smaller value, and a larger inline Reply hits
a receive length error and forces another disconnect.

The undersized rep returns to the free list when its failed Receive
flushes, so the following reconnect reposts the same rep and fails the
same way. The transport flaps without making forward progress for as
long as the peer keeps advertising the larger inline size.

This is local/admin-triggerable rather than remote-triggerable: a local
administrator must create and maintain the NFS/RDMA mount, while the
server or reconnect target has to advertise a larger inline send size
and return a reply that uses it.

Fix this by checking each rep before it is reposted. If the receive
regbuf is smaller than the current endpoint's inline receive size,
reallocate it on the current RDMA device's NUMA node and reinitialize
the rep's xdr_buf before DMA-mapping and posting the Receive WR.

Subject: [PATCH 3298/5214] xprtrdma: Fix bcall rep leak and unbounded peek

rpcrdma_is_bcall() decodes a reply's first words to decide whether
the frame is a backchannel call. Two issues in that decode path
let a short or malformed reply leak the receive buffer and drain
the Receive queue.

First, the speculative peek

    p = xdr_inline_decode(xdr, 0);
    /* five p++ reads follow */

asks xdr_inline_decode() for zero bytes, which returns xdr->p
without consulting xdr->end. The five subsequent __be32 reads can
then walk up to 20 bytes past the wire payload into stale regbuf
contents and misclassify the reply as a backchannel call.

Second, after the post-peek

    p = xdr_inline_decode(xdr, 3 * sizeof(*p));
    if (unlikely(!p))
            return true;

the short-header arm returns true without calling
rpcrdma_bc_receive_call(). The contract with the caller is that a
true return transfers ownership of rep to the backchannel path:

    rpcrdma_reply_handler()
      if (rpcrdma_is_bcall(r_xprt, rep))
              return;        /* bare return, skips out_post */
      ...
    out_post:
      rpcrdma_post_recvs(r_xprt, credits + ...);

Because rpcrdma_bc_receive_call() never ran, no one took rep, but
rpcrdma_reply_handler still bare-returns past rpcrdma_rep_put()
and rpcrdma_post_recvs(). The rep, with its persistently
DMA-mapped receive buffer, is orphaned on rb_all_reps and freed
only at transport teardown. This completion reposts nothing, so
its slot is reclaimed only when a later forward-channel reply
reaches out_post and rpcrdma_post_recvs() allocates a fresh rep to
backfill; absent that traffic the Receive queue drains and the
peer's Sends draw RNR NAKs.

Fix by consulting xdr->end after the zero-length peek so the five
__be32 reads cannot run unless 20 bytes of wire payload remain. A
byte-precise comparison against xdr->end is required because a
non-4-aligned receive rounds the stream's word count up past the
true payload. Also return false from the short-header arm so the
reply falls through the normal out_norqst cleanup chain
(rpcrdma_rep_put() plus rpcrdma_post_recvs()).

Subject: [PATCH 3299/5214] xprtrdma: Sanitize the reply credit grant after
 parsing

The out_norqst exit in rpcrdma_reply_handler() branches away before
the credit clamp, so a reply that matches no pending request reaches
out_post carrying the raw credit value parsed from the wire.
rpcrdma_post_recvs() does not bound its @needed argument: the refill
loop allocates and chains Receive WRs until the count is satisfied or
allocation fails. A peer that sends a well-formed reply carrying an
unknown XID and an inflated credit grant therefore drives rep
allocation and Receive posting past re_max_requests on every such
reply.

Move the clamp to immediately after the credit field is parsed,
ahead of the first branch that can reach out_post, so every later
consumer sees a sanitized value. The cwnd update stays on the
matched-request path.

Subject: [PATCH 3300/5214] xprtrdma: Repost Receive buffers for malformed
 replies

rpcrdma_wc_receive() decrements the transport's Receive count for
every completion before it dispatches a successful Receive to
rpcrdma_reply_handler(). The handler must post a replacement
Receive WR before returning unless ownership of the rep has moved
elsewhere, as on the backchannel path.

Commit 2ae50ad68cd7 ("xprtrdma: Close window between waking RPC
senders and posting Receives") moved the Receive refill out of
rpcrdma_wc_receive(), where it had run ahead of every reply, into
rpcrdma_reply_handler() so that the responder's credit grant could
be parsed before reposting. The bad-version and short-reply exits
never reach that refill: they recycle the rep and return without
calling rpcrdma_post_recvs().

A remote peer can therefore drain the client's posted Receive
queue by sending a sustained stream of replies that are shorter
than the fixed transport header or that carry an unrecognized
RPC/RDMA version. Each such reply consumes one posted Receive
without replacing it. Once the queue empties, the peer's next
Send finds no posted Receive and the transport stalls until
reconnect.

Route both malformed-reply exits through the shared repost tail
after recycling the rep, refilling against buf->rb_credits, the
most recent accepted credit grant. Neither exit updates the
congestion window, so RPCs admitted under the previous grant
remain in flight awaiting replies. A smaller refill target would
let a stream of malformed replies ratchet the posted Receive count
down to the batch floor while the congestion window still admits
rb_credits RPCs; a burst of valid replies to those RPCs could then
overrun the posted Receives, and because the client connects with
rnr_retry_count of zero, a single RNR NAK terminates the
connection. Refilling against rb_credits also restores the target
that applied to malformed replies before commit 2ae50ad68cd7
("xprtrdma: Close window between waking RPC senders and posting
Receives") when rpcrdma_post_recvs() computed it from rb_credits
internally. rb_credits is at least one from connection
establishment onward, so the repost path always keeps Receives
posted.

Subject: [PATCH 3301/5214] xprtrdma: Return sendctx slot after Send
 preparation failure

rpcrdma_prepare_send_sges() gets a sendctx before it maps the SGEs
for the Send WR. If one of the mapping helpers fails, no Send WR
is posted, so no Send completion is guaranteed to advance rb_sc_tail.

Current cleanup clears sc_req so a later completion can sweep over
that slot, but a consecutive run of preparation failures can still
advance rb_sc_head until the ring appears full. At that point
rpcrdma_sendctx_get_locked() returns NULL and no Send can be posted to
produce the completion needed to recover the ring.

The trigger requires CONFIG_SUNRPC_XPRT_RDMA and an NFS/RDMA mount.
Mount setup and reliable DMA-map fault injection require local admin
authority. Unprivileged I/O on an existing mount can exercise the send
path, but a remote peer alone cannot force this local DMA-map failure.

Add rpcrdma_sendctx_unget_locked() for the single-consumer send path
to rewind rb_sc_head when the just-acquired sendctx is canceled before
ib_post_send(). Wake waiters after making the slot available again.
After the rewind, every slot the completion sweep visits belongs to a
posted Send, so rpcrdma_sendctx_put_locked() no longer needs to test
sc_req before unmapping.

Subject: [PATCH 3304/5214] kbuild: Use ld.lld for linking host programs when
 LLVM is set

Currently, host programs are linked with HOSTCC using the toolchain's
default linker. This can result in confusing behavior when using the
LLVM Kbuild variable (which states that the user would like to build
with the LLVM toolchain instead of the GNU one), as clang's default
linker is ld for most platforms, not ld.lld. The documentation mentions
HOSTLD=ld.lld is set but this variable is not used by Kbuild proper,
only within some tools/ projects. Kbuild provides the HOSTLDFLAGS
variable, which allow users to provide the '-fuse-ld' or '--ld-path'
flags to customize what linker is used, but this is not super obvious to
folks not familiar with Kbuild.

If the user has not customized the linker already using one of these
flags, default to ld.lld when using the LLVM variable, which is more in
line with user expectations when using that variable.

Closes: https://github.com/ClangBuiltLinux/linux/issues/2167

Subject: [PATCH 3307/5214] perf s390: Fix TEXTREL in Python extension by
 compiling as PIC

On s390 the Python extension build fails as follows when using a linker
that is configured to treat text relocations (TEXTREL) in shared
libraries as error by default:

  GEN     python/perf.cpython-314-s390x-linux-gnu.so
/usr/bin/ld.bfd: error: read-only segment has dynamic relocations

This occurrs because util/llvm-c-helpers.o is erroneously built from
util/llvm-c-helpers.cpp without compiler option -fPIC but linked into
the shared library (via libperf-util.a(perf-util-in.o)).

On s390, object files must be compiled as position-indepedent code (PIC)
in order to be linked into shared libraries.  Commit a9a3f1d18a6c ("perf
s390: Always build with -fPIC") added compiler option -fPIC to CFLAGS
for s390, which is used in C compiles.  Add -fPIC to CXXFLAGS for s390
as well, so that it is also used in C++ compiles.

Fixes: a9a3f1d18a6c9ccf ("perf s390: Always build with -fPIC")

 time-filtered samples

When samples are skipped due to time filtering in process_sample_event(),
the early return path bypasses addr_location__exit(), causing memory leaks
of thread, map, and maps references acquired by machine__resolve().

These references must be released through addr_location__exit() before
returning.

Subject: [PATCH 3309/5214] perf tools: Fix the check for parameterized field
 in event term

The format_alias() function in util/pmu.c has a check to
detect whether the event has parameterized field ( =? ).
The string alias->terms contains the event and if the event
has user configurable parameter, there will be presence of
sub string "=?" in the alias->terms.

Snippet of code:

 /* Paramemterized events have the parameters shown. */
       if (strstr(alias->terms, "=?")) {
               /* No parameters. */
               snprintf(buf, len, "%.*s/%s/", (int)pmu_name_len, pmu->name, alias->name);

if "strstr" contains the substring, it returns a pointer
and hence enters the above check which is not the expected
check. And hence "perf list" doesn't have the parameterized
fields in the result.

Fix this check to use:

if (!strstr(alias->terms, "=?")) {

With this change, perf list shows the events correctly with
the strings showing parameters.

Before the fix:

 # ./perf list|grep -w PM_PAU_CYC
  hv_24x7/PM_PAU_CYC/                                [Kernel PMU event]

With this fix:

 # ./perf list|grep -w PM_PAU_CYC
  hv_24x7/PM_PAU_CYC,chip=?/                         [Kernel PMU event]

 write helper

lpi_gpio_write() became unused after the PM clock runtime conversion
switched write paths to register helper calls inside callers that already
hold an active runtime-PM reference.

With -Werror this triggers:
  error: 'lpi_gpio_write' defined but not used [-Wunused-function]

Drop the dead wrapper and rename the low-level MMIO helpers from
__lpi_gpio_* to lpi_gpio_*_reg for neutral register-accessor naming.

Subject: [PATCH 3311/5214] pinctrl: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace in the list
terminator.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 3312/5214] pinctrl: qcom: eliza: Add missing sdc2 pin function
 mappings

GPIOs 38, 39, 48 and 49 support the SDC2 DATA function, while
GPIO 51 supports SDC2 CMD and GPIO 62 supports SDC2 CLK.

However, the sdc2 pin function is not listed in the corresponding
pingroup definitions, preventing these pins from being muxed for
SDC2 operation.

Add the missing sdc2 function mappings.

Subject: [PATCH 3313/5214] perf pmu: Use scnprintf in buffer offset
 calculations

Replace snprintf with scnprintf in buffer offset calculations to
ensure the 'used' count will not exceed the "len".

The current logic in perf_pmu__for_each_event uses an unconditional
+ 1 increment to buf_used to account for null terminators. This can
cause a stack buffer overflow in the subsequent scnprintf call.
When the local stack buffer buf (1024 bytes) is full, buf_used can
reach 1025. This causes the subsequent remaining space calculation
sizeof(buf) - buf_used to underflow.

Use sub_non_neg() to see if space actually existed, and only
increment the offset if remaining space is present.

Changes includes:
- Use sub_non_neg to check if space exists
- Replacing snprintf with scnprintf to ensure the return value
reflects the actual bytes written into the buffer.
- Only increment buf_used by 1 if space exists
- If a parameterized event uses a built-in perf keyword for its
parameter name (eg, config=?), the lexer parses it as a predefined
term token, which sets term->config to NULL. Add check to use
parse_events__term_type_str() if term->config is NULL.

Subject: [PATCH 3314/5214] perf cs-etm: Queue context packets for frontend

PE_CONTEXT elements update the context ID and exception level, but the
decoder may still have prior packets cached for frontend processing.
Updating the context immediately in the decoder backend can make those
cached packets get consumed with the wrong thread or EL state.

Add a CS_ETM_CONTEXT packet carrying the TID and EL to the frontend,
this keeps context changes ordered with the rest of the packet stream
and avoids mismatches when synthesizing samples from cached packets.

Separate the memory access function into one for the frontend and one
for decoding. The frontend also needs memory access to attach the
instruction to samples. Because the frontend does memory access for
both previous and current packets, change all the frontend memory access
function signatures to take both a tidq and packet. But backend always
uses the current backend EL and thread from the tidq.

Treat context packets as a boundary for branch sample generation and
remove tidq->prev_packet_thread because it's not possible to branch to a
different thread, so only tracking the current thread is required for
sample generation.

Subject: [PATCH 3315/5214] perf test: Add workload-ctl option

Add a --workload-ctl=fifo:ctl-fifo[,ack-fifo] option for 'perf test
-w'. When set, run_workload() opens the named FIFO, writes enable before
invoking the builtin workload, writes disable before returning, and
waits for ack responses when an ack FIFO is provided to ensure that the
workload doesn't run until the events are enabled.

This can be used to limit the scope of the recording to only the
workload execution and avoid recording Perf setup and teardown code if
Perf record is started with events disabled (-D 1).

Subject: [PATCH 3319/5214] perf test cs-etm: Replace unroll loop thread with
 deterministic decode test

Testing a long sequence without branches seems like it would be better
as a decoder unit test, and this test doesn't test decoding either, so
it's not clear what bugs this is trying to catch.

The new deterministic workload has somewhat long sequences when built
unoptimized, and we can always increase them later if we want to. But
now we test that decoding always gives the same result for the same
sequence of code which we've never had before.

Subject: [PATCH 3320/5214] perf test cs-etm: Remove asm_pure_loop test

It's not obvious what this test is for so remove it. It's not a stress
test because it doesn't output lots of data and it's not a functional
test because it only looks for raw trace output. It seems to imply that
a program written in assembly influences whether trace would be
generated by the CPU or not, but the CPU doesn't know what language the
program is written in.

We already have lots of Coresight tests that test the full pipeline
including decoding, and in many more modes of operation than this one,
so if no trace was collected they will already fail leaving this one
redundant.

Subject: [PATCH 3321/5214] perf test cs-etm: Replace memcpy test with raw dump
 stress test

Like asm_pure_loop, this memcpy test only checks that 10 of each of a
few trace packet types occur after recording a lot of trace, which isn't
more specific than other existing Coresight tests.

Assume it was supposed to be a stress test for dumping and replace it
with one that doesn't require a custom binary and checks for a specific
amount of raw output. Don't bother checking for packets because the
other tests that test decoding will catch issues with malformed data.

This also adds coverage for exit snapshot mode which was missing.

Add a workload that runs X threads that run a unique function named
"named_threads_thread[x]" which performs a multiplication in a loop for
Y loops. Each thread sets its name to "thread[x]".

This can be used to test that processor trace decoding handles
concurrent threads correctly and the correct symbols and thread names
are assigned to samples.

Subject: [PATCH 3323/5214] perf test cs-etm: Test decoding for concurrent
 threads test

The thread_loop test only looks for context IDs in the raw trace.
There's a lot more that can go wrong when decoding these, so replace it
with a test that looks at the final output for matching thread names and
symbols.

In the future we might use timestamps and context switch events to track
threads, so looking at context IDs in the raw trace wouldn't always
work.

Subject: [PATCH 3324/5214] perf test cs-etm: Remove duplicate branch tests

We already test branch output in perf script mode, but then retest it in
Perf report mode. This is more of a test of Perf itself than Coresight
because Perf uses the same samples to generate both outputs. Also we're
already testing instruction output in Perf report mode.

Remove this test for a speedup. On the systemwide test also remove the
Perf report test because systemwide mode records a lot more data so
running multiple tests on it has a big runtime impact.

Subject: [PATCH 3327/5214] perf test cs-etm: Speed up basic test

Like the name says, this should be the most basic test possible. Kernel
recording is slow and already has coverage on the systemwide test. Perf
report output also has coverage elsewhere. 'ls' also produces more trace
than 'true'.

We only want to test if the combination of recording options works at
all, so fix all of these things to make it as fast as possible.

 Perf test - Verify kernel and userspace perf CoreSight work
 -----------------------------------------------------------
 
-When you run perf test, it will do a lot of self tests. Some of those
-tests will cover CoreSight (only if enabled and on ARM64). You
-generally would run perf test from the tools/perf directory in the
-kernel tree. Some tests will check some internal perf support like:
+There are a set of Perf tests for CoreSight which can be run with::
 
-   Check Arm CoreSight trace data recording and synthesized samples
-   Check Arm SPE trace data recording and synthesized samples
-
-Some others will actually use perf record and some test binaries that
-are in tests/shell/coresight and will collect traces to ensure a
-minimum level of functionality is met. The scripts that launch these
-tests are in the same directory. These will all look like:
-
-   CoreSight / ASM Pure Loop
-   CoreSight / Memcpy 16k 10 Threads
-   CoreSight / Thread Loop 10 Threads - Check TID
-   etc.
-
-These perf record tests will not run if the tool binaries do not exist
-in tests/shell/coresight/\*/ and will be skipped. If you do not have
-CoreSight support in hardware then either do not build perf with
-CoreSight support or remove these binaries in order to not have these
-tests fail and have them skip instead.
-
-These tests will log historical results in the current working
-directory (e.g. tools/perf) and will be named stats-\*.csv like:
-
-   stats-asm_pure_loop-out.csv
-   stats-memcpy_thread-16k_10.csv
-   ...
-
-These statistic files log some aspects of the AUX data sections in
-the perf data output counting some numbers of certain encodings (a
-good way to know that it's working in a very simple way). One problem
-with CoreSight is that given a large enough amount of data needing to
-be logged, some of it can be lost due to the processor not waking up
-in time to read out all the data from buffers etc.. You will notice
-that the amount of data collected can vary a lot per run of perf test.
-If you wish to see how this changes over time, simply run perf test
-multiple times and all these csv files will have more and more data
-appended to it that you can later examine, graph and otherwise use to
-figure out if things have become worse or better.
-
-This means sometimes these tests fail as they don't capture all the
-data needed. This is about tracking quality and amount of data
-produced over time and to see when changes to the Linux kernel improve
-quality of traces.
-
-Be aware that some of these tests take quite a while to run, specifically
-in processing the perf data file and dumping contents to then examine what
-is inside.
-
-You can change where these csv logs are stored by setting the
-PERF_TEST_CORESIGHT_STATDIR environment variable before running perf
-test like::
-
-   export PERF_TEST_CORESIGHT_STATDIR=/var/tmp
-   perf test
-
-They will also store resulting perf output data in the current
-directory for later inspection like::
-
-   perf-asm_pure_loop-out.data
-   perf-memcpy_thread-16k_10.data
-   ...
-
-You can alter where the perf data files are stored by setting the
-PERF_TEST_CORESIGHT_DATADIR environment variable such as::
-
-   PERF_TEST_CORESIGHT_DATADIR=/var/tmp
-   perf test
-
-You may wish to set these above environment variables if you wish to
-keep the output of tests outside of the current working directory for
-longer term storage and examination.

Subject: [PATCH 3329/5214] perf test cs-etm: Make disassembly test use kcore

Hits in modules return empty disassembly with vmlinux as an input to
objdump. Make the disassembly test more reliable by always using kcore.
And update the comments to say that this is supported by the script.

Subject: [PATCH 3330/5214] perf test cs-etm: Add all branch instructions to
 test

If we reduce the number of samples searched to speed up the test, then
there will be less chance of hitting one of these branches. Extend the
regex to cover all branches so the test will always pass.

Subject: [PATCH 3331/5214] perf test cs-etm: Speed up disassembly test

We can use exit snapshot to limit the amount of trace to decode here
too. Also each call to objdump is quite expensive on kcore so limit it
to 2 samples instead of 30. We only want to see if there is no data at
all.

Subject: [PATCH 3334/5214] perf pmu: Fix pmu_id() heap underwrite on empty
 identifier file

pmu_id() calls filename__read_str() then strips the trailing newline
via str[len - 1] = 0.  If the PMU identifier file is empty,
filename__read_str() succeeds with len = 0.  len - 1 underflows
size_t to SIZE_MAX, writing a null byte before the heap allocation.

Add a len == 0 check before the newline stripping.

 access on empty sysfs file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

perf_pmu__parse_scale() reads a PMU scale file then accesses
scale[sret - 1] to strip a trailing newline.  Only sret < 0 is
guarded, so an empty file (sret == 0) causes scale[-1] — a stack
buffer underflow that reads and potentially writes out of bounds.

perf_pmu__parse_unit() has the same pattern: alias->unit[sret - 1]
with sret == 0 accesses the byte before the struct member, which
may corrupt the adjacent pmu_name pointer field.

Change both guards from sret < 0 to sret <= 0 so that empty files
are treated as read errors.

Subject: [PATCH 3336/5214] tools lib api: Fix missing null termination in
 filename__read_int/ull()

filename__read_int() passes a stack buffer to read() using the full
sizeof(line) and then hands it to atoi() without null-terminating.
If a sysfs file fills the 64-byte buffer exactly, atoi() reads past
the array into uninitialized stack memory.

filename__read_ull_base() has the same issue with strtoull().

Fix both by reading sizeof(line) - 1 bytes and explicitly
null-terminating after a successful read.

Subject: [PATCH 3337/5214] perf symbols: Fix signed overflow in
 sysfs__read_build_id() size check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sysfs__read_build_id() reads ELF note headers from sysfs files.  The
note's namesz and descsz fields are used to compute the skip size:

    int n = namesz + descsz;
    if (n > (int)sizeof(bf))

Both namesz and descsz are size_t from NOTE_ALIGN() of 32-bit note
header fields.  Their sum can exceed INT_MAX, overflowing the signed
int n to a negative value.  The check n > sizeof(bf) then evaluates
false (negative < positive in signed comparison), and read(fd, bf, n)
reinterprets the negative n as a huge size_t count — the kernel writes
up to MAX_RW_COUNT bytes into the 8192-byte stack buffer.

In practice the overflow is bounded by the sysfs file's actual size,
so a real sysfs notes file won't trigger it organically.  But crafted
input (e.g. via a mounted debugfs/sysfs image) could.

Fix by validating namesz and descsz individually against the buffer
size before summing, and change n to size_t to avoid the signed
overflow entirely.

Subject: [PATCH 3338/5214] perf symbols: Bounds-check .gnu_debuglink section
 data

filename__read_debuglink() copies .gnu_debuglink section data into a
caller-provided buffer via:

    strncpy(debuglink, data->d_buf, size);

where size is PATH_MAX.  If the ELF section is smaller than size and
lacks a null terminator, strncpy reads past data->d_buf into adjacent
memory.  A malformed ELF file can trigger this, potentially causing a
segfault or leaking heap data.

Additionally, strncpy does not guarantee null termination when the
source fills the buffer.

Replace with an explicit memcpy bounded by both the output buffer
size and the actual section data size (data->d_size), followed by
explicit null termination.

Subject: [PATCH 3340/5214] perf intel-pt: Fix snprintf size tracking bug in
 insn decoder

dump_insn() tracks remaining buffer space with a 'left' variable,
but the loop subtracts the cumulative offset 'n' each iteration
instead of just the per-iteration delta:

    n += snprintf(x->out + n, left, "%02x ", inbuf[i]);
    left -= n;  /* BUG: n is cumulative, not the delta */

After two iterations left goes massively negative, wrapping to a
huge value when passed as size_t to snprintf(), disabling all bounds
checking for the rest of the loop.

Switch to scnprintf() accumulation using sizeof(x->out) - n as the
remaining space, which is always correct and eliminates the separate
'left' variable entirely.

 empty comm file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

thread__set_comm_from_proc() calls procfs__read_str() then strips
the trailing newline via comm[sz - 1] = '\0'.  procfs__read_str()
allocates the buffer before reading, so on an empty /proc/pid/comm
(reachable during late exit teardown) it returns success with sz = 0
and an unterminated heap buffer.

The sz - 1 underflow was the original sashiko finding: it writes a
null byte before the allocation.  But even with a sz > 0 guard on
the newline strip, the unterminated buffer would still be passed to
thread__set_comm() which calls strlen() — an unbounded heap read.

Fix by treating sz == 0 as failure: free the buffer and return -1.
This is consistent with pmu.c's perf_pmu__parse_scale/unit which
already treat len == 0 from filename__read_str as an error.

Subject: [PATCH 3342/5214] perf hwmon: Fix off-by-one null termination on
 sysfs reads

Three functions read sysfs files into fixed-size stack buffers using
the full buffer size, then null-terminate at buf[read_len].  If the
read fills the buffer exactly, read_len equals sizeof(buf) and the
null byte writes one past the array, corrupting an adjacent stack
variable.

Fix all three by reading sizeof(buf) - 1 bytes, reserving space for
the null terminator:

  - hwmon_pmu__read_events(): buf[128]
  - hwmon_pmu__describe_items(): buf[64]
  - evsel__hwmon_pmu_read(): buf[32]

Subject: [PATCH 3343/5214] perf hwmon: Use scnprintf() in
 hwmon_pmu__for_each_event()

hwmon_pmu__for_each_event() formats description strings via:

    len = snprintf(desc_buf, sizeof(desc_buf), "%s in unit %s named %s.", ...);
    len += hwmon_pmu__describe_items(hwm, desc_buf + len, sizeof(desc_buf) - len, ...);

If value->label is long enough to cause snprintf() to truncate, it
returns the would-have-been-written count, making len exceed
sizeof(desc_buf).  The subsequent sizeof(desc_buf) - len underflows
to a huge size_t value, disabling bounds checking in
hwmon_pmu__describe_items().

The alias_buf snprintf has the same issue.  Switch both to scnprintf()
which returns actual bytes written.

Subject: [PATCH 3344/5214] perf hwmon: Fix parse_hwmon_filename() strlcpy
 buffer overflow

parse_hwmon_filename() strips the "_alarm" suffix from event names
by copying into a 24-byte stack buffer:

    strlcpy(fn_type, fn_item, fn_item_len - 5);

The third argument is the source length minus the suffix, not the
destination buffer capacity.  A long event name ending in "_alarm"
can have fn_item_len - 5 > sizeof(fn_type), causing strlcpy() to
write past the 24-byte fn_type[] array.  The assert() only validates
that the longest *valid* hwmon item fits, but does not protect
against crafted input.

Clamp the strlcpy size to min(fn_item_len - 5, sizeof(fn_type)).

Subject: [PATCH 3345/5214] perf symbols: Bounds-check descsz in
 sysfs__read_build_id() GNU fallback

When sysfs__read_build_id() matches NT_GNU_BUILD_ID with the right
namesz but the name content is not "GNU", it falls back to reading
descsz bytes into the stack buffer bf[BUFSIZ]:

    } else if (read(fd, bf, descsz) != (ssize_t)descsz)

Unlike the else branch which validates namesz + descsz against
sizeof(bf), this path passes descsz directly to read() without any
bounds check.  A crafted sysfs file with a large n_descsz overflows
the 8192-byte stack buffer.

Add a descsz > sizeof(bf) check before the read, breaking out of
the loop on oversized values.

Subject: [PATCH 3346/5214] perf tools: Fix uninitialized pathname on
 uncompressed fallback in filename__decompress()

filename__decompress() has an early return path for files that are not
actually compressed.  This path returns the fd from open() directly but
never writes to the pathname output parameter, leaving the caller with
an uninitialized buffer despite a successful return.

Callers like dso__decompress_kmodule_path() pass pathname to
decompress_kmodule() which uses it to set the decompressed file path.
If pathname is uninitialized, subsequent operations on the path produce
undefined behavior.

Fix by setting pathname to an empty string on the uncompressed path.
Callers already check for an empty pathname to distinguish temporary
decompressed files (which need unlink) from the original file.

Subject: [PATCH 3347/5214] perf hwmon: Guard label read against empty or
 failed reads

hwmon_pmu__read_events() reads label files with read() into a stack
buffer, strips trailing newlines, then checks buf[0] == '\0'.  When
read() returns 0 (empty file) or -1 (error), the buffer is never
written, so buf[0] reads uninitialized stack memory.  If the garbage
byte is non-zero, the code falls through to strdup(buf) which copies
arbitrary stack data as the label string.

Fix by checking read_len <= 0 before accessing buf contents, closing
the fd and skipping the entry.

Subject: [PATCH 3350/5214] tools lib api: Fix mount_overload() snprintf
 truncation and toupper range

mount_overload() builds an environment variable name like
"PERF_SYSFS_ENVIRONMENT" from fs->name.  Two bugs:

1) snprintf() uses name_len as the buffer size instead of sizeof(upper_name).
   For fs->name = "sysfs" (len=5), the output is truncated to "PERF" (4
   chars + null), so getenv() never finds the intended variable.

2) mem_toupper() only uppercases name_len bytes, converting just the "PERF"
   prefix rather than the full string including the filesystem name portion.

Fix by using sizeof(upper_name) for snprintf and strlen(upper_name) for
mem_toupper, so the full "PERF_SYSFS_ENVIRONMENT" string is correctly
formatted and uppercased.

Subject: [PATCH 3351/5214] perf bpf: Add NULL check for btf__type_by_id() in
 synthesize_bpf_prog_name()

synthesize_bpf_prog_name() calls btf__type_by_id() and immediately
dereferences the result via t->name_off without checking for NULL.
btf__type_by_id() returns NULL when the type_id is invalid or out
of range.  When processing perf.data files, finfo->type_id comes from
untrusted input, so an invalid ID causes a NULL pointer dereference.

Fix by checking t for NULL before dereferencing.

Subject: [PATCH 3352/5214] perf bpf: Fix map data leak in
 bpf_metadata_create() on alloc failure

bpf_metadata_create() calls bpf_metadata_read_map_data() which
allocates map.btf and map.rodata.  If the subsequent
bpf_metadata_alloc() fails, the code does 'continue' which skips
bpf_metadata_free_map_data(), permanently leaking both allocations.

Fix by calling bpf_metadata_free_map_data() before continue.

When perf_env__insert_bpf_prog_info() returns false (duplicate

metadata allocation is permanently leaked.

Fix by calling bpf_metadata_free() on info_node->metadata before

safe even when bpf_metadata_create() returned NULL.

Subject: [PATCH 3356/5214] Input: ads7846 - don't use scratch for tx_buf when
 clearing register

The workaround for XPT2046 clears the command register, giving the
touchscreen controller a NOP. The change incorrectly re-uses the
req->scratch variable which is used as rx_buf for xfer[5], so by
the time xfer[6] occurs, the contents of req->scratch may not be
0. It was found that the touchscreen controller can end up in
a completely unresponsive state due to it being given a command
the driver does not expect.

Instead, rely on the spi_transfer behavior of tx_buf being NULL to
transmit all 0 bits and use the scratch variable for the rx_buf for
both the 1 byte command to and 2 byte response from the controller.

Also relocates the scratch member of struct ser_req to force it
into a different cache line to prevent any potential issues of
DMA stepping on unrelated data in other struct members due to
sharing the same cache line.

This change was tested on real TSC2046 and ADS7843 controllers,
but not the XPT2046 the workaround was originally created for.
Confirming that the original modification to clear the command
register does not impact either real controller.

Add documentation for the dma-channel-mask property in the fsl-edma
binding. This property uses an inverted bit definition: bit value 0
indicates the channel is available, while bit value 1 indicates
unavailable.

That was already used widely for i.MX8, i.MX9. Correcting the definition
will break backward compatibility. This reversal only impacts the eDMA
dts node and driver, and doesn't impact DMA consumer. Therefore,
keep the inverted definition.

Also add a note at the top of the binding to highlight this inverted
definition to prevent confusion.

Subject: [PATCH 3359/5214] dmaengine: altera-msgdma: Use memcpy_toio for
 descriptor FIFO writes

The descriptor FIFO requires that all words of a descriptor are written
in order, with the control word written last to flush it into the DMA
engine. Using memcpy() with __force to __iomem is not the correct API
and does not guarantee appropriate MMIO access on all architectures.

Replace the descriptor body copy with memcpy_toio(), using
offsetof(struct msgdma_extended_desc, control) to exclude the control
word. This matches the previous sizeof(desc->hw_desc) - sizeof(u32)
length only when control is the last struct member; add a static_assert
to enforce that layout so a future field after control cannot silently
break FIFO ordering.

Keep writing the control word separately with write barriers, so it
remains the final word pushed into the FIFO.

Subject: [PATCH 3361/5214] dmaengine: dw-axi-dmac: fix PM for system sleep and
 channel alloc

The driver only had runtime PM callbacks. If a channel stayed allocated
across system suspend/resume, the runtime usage count could remain
non-zero while hardware state (DMAC_CFG, clocks) was lost, and
axi_dma_runtime_resume() would not run to restore it.

Add system-sleep PM ops that use pm_runtime_force_suspend() and
pm_runtime_force_resume() so suspend/resume reuses the existing
axi_dma_suspend() and axi_dma_resume() paths.

Replace pm_runtime_get() with pm_runtime_resume_and_get() in
dma_chan_alloc_chan_resources() so clocks are enabled before a client
can immediately submit a transfer and touch MMIO.

 i2c_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 3370/5214] phy: qcom: qmp-pcie: Add QMP PCIe PHY support for
 Eliza

Add QMP PCIe PHY support for the Eliza SoC. Introduce a new Gen3x1 PHY
configuration with Eliza-specific initialization tables, and reuse the
existing sm8550 Gen3x2 configuration for the Gen3x2 PHY instance.

Also add the missing QPHY_PCIE_V6_PCS_PCIE_INT_AUX_CLK_CONFIG1 register
definition to the PCIe V6 PCS header.

Subject: [PATCH 3371/5214] PCI: mediatek: Use actual physical address instead
 of virt_to_phys()

The driver previously used virt_to_phys() on the ioremapped register base
(port->base) to compute the MSI message address. Using virt_to_phys() on an
IO mapped address is incorrect because it expects a kernel virtual address.

To fix it, store the physical start of the I/O register region in
mtk_pcie_port->phys_base and use it to build the MSI address. This replaces
the incorrect virt_to_phys() usage and ensures MSI addresses are generated
correctly.

Subject: [PATCH 3373/5214] phy: lynx-28g: avoid returning NULL in of_xlate()
 function

Sashiko points out that _of_phy_get() does not support a NULL returned
output from phy_provider->of_xlate(), just a valid pointer or a
pointer-encoded error.

When lynx_28g_probe() -> for_each_available_child_of_node() skips
over lanes which have OF nodes with status = "disabled", the
priv->lane[idx].phy pointer will remain NULL.

This NULL pointer may be propagated to lynx_28g_xlate() if the device
tree contains a phandle to the disabled lane AND fw_devlink did not
block probing for the consumer. In that case, the PHY core will crash
when trying to dereference the NULL phy pointer.

Subject: [PATCH 3374/5214] phy: lynx-28g: reject probing on devices with
 unsupported OF nodes

It is possible to bind the lynx-28g driver to an arbitrary device with
an OF node, using the driver_override mechanism that is available for
the platform bus, and trigger a crash this way:

$ echo 1ea0000.serdes > /sys/bus/platform/drivers/lynx-10g/unbind
$ echo lynx-28g > /sys/bus/platform/devices/1ea0000.serdes/driver_override
$ echo 1ea0000.serdes > /sys/bus/platform/drivers/lynx-28g/bind
Internal error: Oops: 0000000096000004 [#1]  SMP
Hardware name: LS1028A RDB Board (DT)
pc : lynx_probe+0x118/0x4fc
lr : lynx_probe+0x110/0x4fc
Call trace:
 lynx_probe+0x118/0x4fc (P)

 device_driver_attach+0x58/0xa8
 bind_store+0xd8/0x118
 drv_attr_store+0x24/0x38

The crash is caused by the fact that of_device_get_match_data() returns
NULL (the bound device has a different compatible string) and this is
not checked.

There was a previous attempt to avoid this in commit c9d80e861034 ("phy:
lynx-28g: require an OF node to probe"), but the mechanism was not fully
understood and it only covered the case where the driver was bound to a
device with no OF node.

The issue was found during Sashiko review. Elevated privilege is
required to override the driver for a device, so the real life impact of
the issue should not be very high.

Subject: [PATCH 3375/5214] phy: lynx-28g: move lane mode helpers to new core
 module

Do some preparation work for the introduction of the lynx-10g driver,
which will share a common backbone with the 28G Lynx SerDes.

This is just trivial stuff which can be moved without any surgery, and
is easy to follow but otherwise pollutes more serious changes.

The lane modes themselves are exported to a public header, because on
the 10G Lynx, the hardware requires implementing a procedure called
"RCW override". This requires coordination with drivers/soc/fsl/guts.c
to tell it that a SerDes lane needs to be switched to a different
protocol (enum lynx_lane_mode).

Subject: [PATCH 3376/5214] phy: lynx-28g: move data structures to core

The goal is to avoid duplicating the core data structures when
introducing the new lynx-10g driver.

We move the following to phy-fsl-lynx-core:
- struct lynx_28g_pll -> struct lynx_pll. This has some
  hardware-specific register fields which need to become hardware
  agnostic (the PLL register layout is different for Lynx 10G), So:
  - PLLnRSTCTL_DIS(pll->rstctl) becomes !pll->enabled
  - PLLnRSTCTL_LOCK(pll->rstctl) becomes pll->locked
  - FIELD_GET(PLLnCR1_FRATE_SEL, pll->cr1) becomes pll->frate_sel
  - FIELD_GET(PLLnCR0_REFCLK_SEL, pll->cr0) becomes pll->refclk_sel
- struct lynx_28g_lane -> struct lynx_lane
- struct lynx_28g_priv -> struct lynx_priv
  - field lane[LYNX_28G_NUM_LANE] has to be dynamically allocated. Not
    all Lynx 10G SerDes blocks have 8 lanes.
- LYNX_28G_NUM_PLL -> LYNX_NUM_PLL. This is an architectural constant
  which is the same for Lynx 10G as well.

To avoid major noise in the lynx-28g driver, we keep compatibility shims
(for now) where the old lynx_28g names are preserved, but translate to
the common data structures.

Subject: [PATCH 3377/5214] phy: lynx-28g: common lynx_pll_get()

The logic should be absolutely unchanged in the new 10G Lynx SerDes
driver, so let's move this to phy-fsl-lynx-core.c and update the 28G
Lynx driver to use the common variant.

While at it, update the call site, lynx_28g_lane_remap_pll(), to use the
new data structures, and refactor the NULL pll pointer check (the
current form triggers a checkpatch CHECK).

Subject: [PATCH 3378/5214] phy: lynx-28g: generalize protocol converter
 accessors

The protocol converters on the 10G Lynx are architecturally similar, but
different in layout from the 28G Lynx ones.

Move lynx_pccr_read(), lynx_pccr_write(), lynx_pcvt_read() and
lynx_pcvt_write() from the 28G Lynx driver to the common module, and
permit each SerDes driver to provide just its own bits in order to use
this common API.

Currently, that just means that the direct calls to
lynx_28g_get_pcvt_offset() are modified to go through the
lynx->info->get_pcvt_offset() indirect function call, and similarly,
lynx_28g_get_pccr() through lynx->info->get_pccr().

Subject: [PATCH 3379/5214] phy: lynx-28g: provide default
 lynx_lane_supports_mode() implementation

For the 28G Lynx, there are situations where a protocol is not supported
on a lane despite there being a PCCR register and protocol converter
available:
- LX2160A SerDes 1: reference manual documents PCCD fields E25GC_CFG and
  E25GD_CFG and protocol converter registers E25GCCR1..E25GCCR3 /
  E25GDCR1..E25GDCR3, but nonetheless, Table 289. SerDes 1 protocol
  mapping shows no RCW[SRDS_PRTCL_S1] value for which lanes C and D
  support 25G
- when using the "fsl,lynx-28g" fallback compatible string, we don't
  want to offer 25GbE because we don't know if the lane supports it,
  even though we know how to reach the PCCR and protocol converter
  registers for it.

But for the upcoming 10G Lynx SerDes, the above situations don't exist.
There, if we know how to reach the PCCR and protocol converter
registers on a lane, we implicitly know that the protocol is supported
there, so implementing priv->info->lane_supports_mode() would be
redundant.

Implement lynx_lane_supports_mode_default() which decides whether a lane
mode is supported just based on priv->info->get_pccr() and
priv->info->get_pcvt_offset().

Subject: [PATCH 3380/5214] phy: lynx-28g: move struct lynx_info definitions
 downwards

We need to be able to reference more function pointers in upcoming
patches. The struct lynx_info definitions are currently placed a bit up
in lynx-28g.c in order to be able to do that without function prototype
forward declarations, so move them downward to avoid that situation.

No functional change intended.

Subject: [PATCH 3381/5214] phy: lynx-28g: make
 lynx_28g_pll_read_configuration() callable per PLL

In a future change, lynx_28g_pll_read_configuration() and
lynx_28g_lane_read_configuration() will be made methods of struct
lynx_info.

There is no functional reason, but lynx_28g_lane_read_configuration() is
called per lane and lynx_28g_pll_read_configuration() iterates over PLLs
internally. So the API exported by the lynx_info structure would not be
uniform. Change lynx_28g_pll_read_configuration() to also permit reading
the PLL configuration individually, and move the for loop at the call
site.

Subject: [PATCH 3382/5214] phy: lynx-28g: common probe() and remove()

Factor the device-agnostic logic from lynx_28g_probe() and
lynx_28g_remove() into lynx_probe() and lynx_remove() inside
phy-fsl-lynx-core.c. These will be shared with the 10G Lynx driver.

Since the PLL configuration, lane configuration and CDR lock detection
procedure are going to be different, introduce lynx_info function
pointers so that this code remains in the 28G Lynx driver.

Some 10G Lynx SerDes blocks are big endian and require byte swapping
because the CPUs are little endian armv8 (LS1046A). Parse the
"big-endian" device tree property, and modify the base lynx_read() and
lynx_write() accessors to test this property before issuing either the
ioread32() or ioread32be() variants (as per
Documentation/driver-api/device-io.rst).

All other accessors - lynx_rmw(), lynx_lane_read(), lynx_lane_write(),
lynx_lane_rmw(), lynx_pll_read() - need to go through these endian-aware
helpers.

It is unnecessary to rewrite a register if the masked field already
contains the desired value upon reading. The hardware behaviour does not
depend upon register writes with identical values.

Subject: [PATCH 3385/5214] phy: lynx-28g: improve phy_validate() procedure

lynx_28g_validate() suffers from the following shortcomings:

- Changing the protocol should not be possible if the source protocol of
  the lane is unsupported. This is because lynx_28g_proto_conf[] only
  covers the register deltas between any pair of supported lane modes,
  but that delta is probably incomplete if the source protocol is, say,
  PCIe (which is currently assimilated by the driver to
  LANE_MODE_UNKNOWN).

  lynx_28g_proto_conf() does refuse changing the protocol if the current
  one is unsupported, but we shouldn't advertise it via phy_validate()
  at all.

  The phy_set_mode_ext() call should perform the exact same
  verifications as phy_validate() did, in case the caller bypassed
  phy_validate(). So we need to centralize the logic into a common
  validation. But lynx_28g_set_mode() later needs the lane_mode that
  this validation needs to compute anyway, so name the common helper
  lynx_phy_mode_to_lane_mode() and let it return that lane_mode.

- Future core sanity checks on phy_validate() will want to differentiate
  the case where this optional method is not implemented from the case
  where the mode/submode is really not supported. So we shouldn't return
  -EOPNOTSUPP from lynx_28g_validate(), but -EINVAL to signal that we do
  implement the operation:

Subject: [PATCH 3386/5214] dt-bindings: phy: lynx-10g: initial document

Add a schema for the 10G Lynx SerDes. This is very similar to the modern
form of the 28G Lynx SerDes, which is very much the intention.

There is intentionally no generic fsl,lynx-10g compatible string due to
the hardware inability to report its capabilities, despite having a
common register map.

We allow both forms of #phy-cells = <1> in the top-level provider
and #phy-cells = <0> in the per-lane provider for more flexibility to
consumers, and because the kernel code is shared with the 28G Lynx which
already has that support for compatibility reasons.

Subject: [PATCH 3387/5214] phy: lynx-10g: new driver

Introduce a driver for the networking lanes of the 10G Lynx SerDes
block, present on the majority of Layerscape and QorIQ (Freescale/NXP)
SoCs.

As with the 28G Lynx, the SerDes lanes come pre-initialized out of
reset and the consumers use them that way outside the Generic PHY
framework (for networking, the static configuration remains for the
entire SoC lifetime, whereas for SATA and PCIe, the hardware
reconfigures itself automatically for other link speeds).

The need for the Generic PHY framework comes specifically for networking
use cases where a static lane configuration is not sufficient. For
example a network MAC is connected to an SFP cage, where various SFP or
SFP+ modules can be connected. Each of them may require a different
SerDes protocol (SGMII, 1000Base-X, 10GBase-R), which phylink + sfp-bus
are responsible of figuring out. The phylink drivers are:
- enetc
- felix
- dpaa_eth (fman_memac)
- dpaa2-eth
- dpaa2-switch

and they all need to reconfigure the SerDes for the requested link mode,
using phy_set_mode_ext() (and phy_validate() to see if it is supported
in the first place).

Note that SerDes 2 on LS1088A is exclusively non-networking, so there is
currently no need for this driver. Therefore we skip matching on its
compatible string and do not probe on that device.

 10G SerDes

The lynx-28g and lynx-10g drivers share code and hardware architecture,
so let them be covered by a single MAINTAINERS entry.

Add myself as a second maintainer alongside Ioana Ciornei.

Subject: [PATCH 3389/5214] mtd: rawnand: ndfc: use ioread32be/iowrite32be and
 allow COMPILE_TEST

Replace ppc4xx-specific in_be32/out_be32 with generic ioread32be/
iowrite32be to make the driver portable. Add COMPILE_TEST dependency
to get build coverage on non-ppc4xx architectures.

While at it, replace 4xx with 44x. The latter was removed a while ago
and is only kept for compatibility.

Subject: [PATCH 3390/5214] mtd: slram: remove failed entries from the device
 list

register_device() links a new slram_mtdlist entry before allocating all
of the state needed by the entry. If a later allocation, memremap(), or
mtd_device_register() fails, the partially initialized entry remains on
the global list. A later cleanup can then dereference or free invalid
state from that failed entry.

Unwind the partially initialized entry and clear the list tail on each
failure path after the entry has been linked.

Subject: [PATCH 3391/5214] mtd: slram: simplify register_device() cleanup

Use local variables for the list entry, mtd_info, and private data while
initializing a new device. This keeps the initialization path easier to
read and publishes the new list entry only after mtd_device_register()
has succeeded.

Subject: [PATCH 3393/5214] phy: freescale: phy-fsl-imx8qm-lvds-phy: Use
 synchronous PM runtime put in reset

The mixel_lvds_phy_reset() function pairs pm_runtime_resume_and_get()
with pm_runtime_put(). The asynchronous variant queues a work item
to handle the idle check and potential suspend, which can be cancelled
by a subsequent pm_runtime_disable() call if probe fails after the reset.

Switch to pm_runtime_put_sync() to run the idle check and suspend
synchronously.

Subject: [PATCH 3396/5214] pinctrl: sunxi: a523: Remove unneeded IRQ remuxing
 flag

The Allwinner A10 and H3 SoCs cannot read the state of a GPIO line when
that line is muxed for IRQ triggering (muxval 6), but only if it's
explicitly muxed for GPIO input (muxval 0). Other SoCs do not show this
behaviour, so we added a optional workaround, triggered by a quirk bit,
which triggers remuxing the pin when it's configured for IRQ, while we
need to read its value.

For some reasons this quirk flag was copied over to newer SoCs, even
though they don't show this behaviour, and the GPIO data register
reflects the true GPIO state even with a pin muxed to IRQ trigger.

Remove the unneeded quirk from the A523 family, where it's definitely
not needed (confirmed by experiments), and where it actually breaks,
because the workaround is not compatible with the newer generation
pinctrl IP used in that chip.

Together with a DT change this fixes GPIO IRQ operation on the A523
family of SoCs, as for instance used for the SD card detection.

Subject: [PATCH 3397/5214] dt-bindings: pinctrl: sun55i-a523: increase IRQ
 banks number

The Allwinner A523 SoC implements 10 GPIO banks in the first pinctrl
instance, but it skips the first bank (PortA), so their index goes from
1 to 10. The same is actually true for the IRQ banks: there are registers
for 11 banks, though the first bank is not implemented (RAZ/WI).
In contrast to previous SoCs, the count of the IRQ banks starts with this
first unimplemented bank, so we need to provide an interrupt for it.
And indeed the A523 user manual lists an interrupt number for PortA, so we
need to increase the maximum number of interrupts per pin controller to 11,
to be able to assign the correct interrupt number for each bank.

Subject: [PATCH 3403/5214] platform/x86: asus-wmi: add keystone dongle support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ASUS Keystone is a physical NFC-like dongle that slots into supported
ASUS laptops. The EC fires WMI notify code 0xB4 on insert/remove events.

Expose the current insert state via a sysfs attribute by querying WMI
device ID 0x00120091 (DSTS). This devid does not follow the standard DSTS
convention: PRESENCE_BIT (0x00010000) encodes the insert state rather than
feature presence, and STATUS_BIT is never set. Presence of a keystone slot
is detected by a successful DSTS call.

Subject: [PATCH 3408/5214] pinctrl: airoha: an7581: fix incorrect led mapping
 in phy4_led1 pin function

phy4_led1 pin function maps led incorrectly. It uses the same map as
phy3_led1. PHY{X} should map to LAN{N}_PHY_LED_MAP(X-1).

Subject: [PATCH 3410/5214] pinctrl: airoha: fix pwm pin function for an7581
 and an7583

AN7581 have 47 valid GPIOs only (gpio0-gpio46), so gpio47 is a fiction.
AN7583 have 49 valid GPIOs (gpio0-gpio48), so gpio48 is missed

To fix an issue
 * create AN7583 specific pwm pin function,
 * remove gpio47 from AN7581 pwm pin function.

Subject: [PATCH 3415/5214] platform/x86: asus-armoury: add support for G614PR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add TDP power limits and fan curve requirements for the ASUS ROG Strix
G16 G614PR laptop model.

The ASUS ROG Strix G16 G614PR requires specific AC/DC power limits
(PPT PL1/PL2/PL3, dynamic boost, and NV TGP targets) to function
correctly under various power profiles. Without these limits, the Asus
Armoury driver cannot configure the correct power envelopes or enable custom
fan curves, leading to suboptimal performance or noise management.

This patch adds the corresponding DMI board name matching entry ("G614PR")
under the power_limits table in asus-armoury.h, populating the AC and DC
limits based on the platform's hardware specification.

Content-Transfer-Encoding: 8bit

Comments in drivers/platform/x86/dell/dell-wmi-privacy.h incorrectly
refer to CONFIG_DELL_PRIVACY instead of CONFIG_DELL_WMI_PRIVACY.
Correct them.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.

Subject: [PATCH 3417/5214] dt-bindings: pinctrl: tegra238: add missing AON pin
 groups

Add 24 pin groups, and their matching drive groups, on ports EE, FF,
GG and HH to the Tegra238 AON pinmux binding. These groups are present
on the AON pin controller, so device trees that mux these pins through
it validate against the schema.

Subject: [PATCH 3418/5214] pinctrl: tegra238: add missing AON pin groups

Add 24 pin groups on ports EE, FF, GG and HH to the AON pin controller
group table (tegra238_aon_groups[]). Their pin arrays, drive-group
macros and pin descriptors were already defined, but the matching
PINGROUP() entries were not present, so these pins could not be muxed
or configured through the AON pin controller.

The pin arrays were not referenced, so the build emitted
-Wunused-const-variable warnings, and commit 119de2c33d96 ("pinctrl:
tegra238: remove unused entries") removed three of them. Restore those
arrays and add the full set of PINGROUP() entries to make the pins
usable.

 ARCH_TEGRA

The NVIDIA Tegra238 MAIN and AON pin controllers are only present on
NVIDIA Tegra238 SoCs.  Hence add a dependency on ARCH_TEGRA, to prevent
asking the user about this driver when configuring a kernel without
NVIDIA Tegra SoC support.

Subject: [PATCH 3420/5214] pinctrl: tegra: PINCTRL_TEGRA264 should depend on
 ARCH_TEGRA

The NVIDIA Tegra264 MAIN, AON, and UPHY pin controllers are only present
on NVIDIA Tegra264 SoCs.  Hence add a dependency on ARCH_TEGRA, to
prevent asking the user about this driver when configuring a kernel
without NVIDIA Tegra SoC support.

Subject: [PATCH 3422/5214] LoongArch: KVM: Add separate KVM_REQ_LBT_LOAD bit

There are different structures with FPU and LBT register restore, with
FPU the structure is vcpu::arch::fpu, with LBT the structure is vcpu::
arch::lbt. Moreover, FPU/LSX/LASX saving and restoring share the common
structure vcpu::arch::fpu.

New request bit KVM_REQ_LBT_LOAD is used for LBT register restore, and
rename KVM_REQ_AUX_LOAD with KVM_REQ_FPU_LOAD for FPU register restore.

Subject: [PATCH 3423/5214] LoongArch: KVM: Enable FPU with max supported FPU
 type

There are three FPU types FPU/LSX/LASX, which represents FPU64, FPU128
and FPU256, and now lazy FPU method is used with FPU enabling. There are
three different HW FPU exception code with different FPU type.

The exising method is to enable specified FPU type with responding FPU
exeception. Supposing application uses FPU64 and FPU256, there will be
FPU256 exception when FPU256 type is used.

Here enable FPU with the max VM supported type directly, so it can avoid
unnecessary FPU exception in future if further FPU type is used.

With max VM supported FPU type enabled, if VM supports LASX, there is
only NONE --> LASX, no middle FPU state such as NONE --> FPU --> LASX
or NONE --> FPU --> LSX --> LASX. Here remove the middle FPU states in
function kvm_own_lsx() and kvm_own_lasx(). And it becomes simpler than
before.

In kvm_lose_fpu() FPU state is save in vcpu::arch::fpu, its FPU status
comes from vcpu->arch.aux_inuse. Instead existing API vm_guest_has_xxx()

arch.aux_inuse are removed. It makes the logic simpler than ever.

Subject: [PATCH 3426/5214] LoongArch: KVM: Fix FPU register width with user
 access API

At the beginning, only 64 bit FPU is supported. With FPU register get
interface, 64 bit FPU data is copied to user space, the same with FPU
register set API. However with LSX and LASX supported in later, there
should be FPU data copied with bigger width. So here fixes this issue,
copy the whole 256 bit FPU data from/to user space.

 bit mask

With interrupt post, register CSR.GINTC and CSR.ESTAT is used, and
CSR.ESTAT is used for percpu interrupt injection and CSR.GINTC is for
external hardware interrupt injection.

Here use existing macro about interrupt bit of register CSR.GINTC and
CSR.ESTAT, rather than hard coded constant value.

Subject: [PATCH 3433/5214] LoongArch: KVM: Remove timer interrupt injection
 when SW timer expired

The software timer emulation is to wake up vCPU when the vCPU executes
idle instruction and gives up host CPU, the vCPU timer tick value and
interrupt is set when vCPU is scheduled in.

It is not necessary to inject timer interrupt when SW timer is expired.
Here remove it, also use common API kvm_vcpu_wake_up() to wake up vCPU.

Subject: [PATCH 3435/5214] LoongArch: KVM: Return full old CSR value from
 kvm_emu_xchg_csr()

The LoongArch CSRXCHG instruction returns the full old CSR value in rd
after applying the masked update. kvm_emu_xchg_csr() currently masks
the saved value before returning it to the guest, so rd receives only
the bits selected by the write mask.

That breaks the architectural behavior and makes a zero mask return 0
instead of the previous CSR value. So, keep the masked CSR update, but
return the unmodified old CSR value.

Add support for the pin controller on the UltraRISC DP1000 SoC.

The controller provides mux selection for pins in ports A, B, C, D, and
LPC. Ports A-D default to GPIO and support peripheral muxing. LPC pins
can be switched to eSPI, but are not available as GPIOs. Basic pin
configuration controls such as drive strength, pull-up, and pull-down
are also supported.

Subject: [PATCH 3441/5214] pinctrl: meson: amlogic-a4: use nolock get range

Use pinctrl_find_gpio_range_from_pin_nolock() instead of
pinctrl_find_gpio_range_from_pin() when configuring a pin or
setting a GPIO value.

This avoids taking the lock and allows the code to be safely
called from interrupt context.

Subject: [PATCH 3442/5214] pinctrl: qcom: Register functions before enabling
 pinctrl

pinctrl consumers can request states while the pinctrl core enables the
controller. On Qualcomm pinctrl drivers this can happen before the SoC
function list has been registered, which leaves the function table
incomplete during state lookup.

On APQ8064 this can fail while claiming pinctrl hogs:

   apq8064-pinctrl 800000.pinctrl: invalid function ps_hold in map table
   apq8064-pinctrl 800000.pinctrl: error claiming hogs: -22
   apq8064-pinctrl 800000.pinctrl: could not claim hogs: -22

Register Qualcomm pinctrl with devm_pinctrl_register_and_init(), add the
SoC pin functions, and only then enable the pinctrl device.

Subject: [PATCH 3443/5214] KVM: s390: Initialize KVM_S390_GET_CMMA_BITS memory

kvm_s390_get_cmma_bits() allocates its output buffer with vmalloc(),
which does not zero the returned pages:

	values = vmalloc(args->count);

In the non-peek (migration) path, dat_get_cmma() reports a byte count
spanning from the first to the last dirty page, but __dat_get_cmma_pte()
writes values[gfn - start] only for pages whose CMMA dirty bit is set.
The walk uses DAT_WALK_IGN_HOLES, so clean and unmapped pages that lie
between two dirty pages within the reported span are visited but never
store their byte.  Those gaps (up to KVM_S390_MAX_BIT_DISTANCE pages
each) stay uninitialized yet fall inside [0, count) and are copied out
by copy_to_user(), disclosing stale kernel memory to user space.

Before the switch to the new gmap implementation the buffer was fully
populated for every gfn in the span, so no uninitialized bytes were
exposed; the dirty-only walk introduced the leak.

Use vzalloc() so the gaps read back as zero.

 pnp_device_id driver data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver explicitly sets the .driver_data member of struct
pnp_device_id to zero without relying on that value. Drop these unused
assignments.

While touching this array use a named initializer for .id for improved
readability and simplify the list terminator.

This patch doesn't modify the compiled array, only its representation in
source form benefits. The former was confirmed with an x86 build.

Subject: [PATCH 3445/5214] pmdomain: core: fix early domain registration

A recent change switching to a dynamically allocated root device broke
platforms like rcar-sysc that registers PM domains before the PM domain
bus itself has been registered (cf. commit c5ae5a0c6112 ("pmdomain:
renesas: rcar-sysc: Add genpd OF provider at postcore_initcall")).

Defer the assignment of the parent root device until the domain is
registered with driver core to avoid it being left unset.

Subject: [PATCH 3446/5214] backlight: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace in the list
terminator.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Subject: [PATCH 3447/5214] perf test: Truncate printed test descriptions
 dynamically to avoid terminal wrapping

When test descriptions are extremely long (e.g., the truncated perf.data
graceful handling test is 103 characters long), they wrap across terminal
boundaries.

Because the ANSI escape code to delete the line (PERF_COLOR_DELETE_LINE)
only clears a single terminal line, visual wrapping leaves orphan
wrapped lines on the screen, which results in the test description being
printed multiple times.

Resolve this by checking the terminal width (get_term_dimensions) and
dynamically truncating the printed test description to fit within the
available columns, leaving safety space for the prefix index and status
suffix.

Also, remove the width padding from the test suite headers which do not
display inline status messages. This prevents their trailing colons from
wrapping onto new lines on standard width terminals.

Finally, avoid GCC 16's -Wformat-truncation warnings by delegating the
description padding to pr_info's %-*s format specifier instead of padding
within a temporary buffer, and clamp the truncation limit to the temporary
buffer's size.

JUnit XML output and the failure summary report still print the full,
untruncated test descriptions.

Subject: [PATCH 3448/5214] phy: freescale: phy-fsl-imx8qm-lvds-phy: Fix
 missing pm_runtime_disable() on probe error path

If mixel_lvds_phy_reset() fails in probe after pm_runtime_enable(),
the function returns directly without calling pm_runtime_disable(),
leaving runtime PM permanently enabled for the device.

Fix this by using devm_pm_runtime_enable() so that cleanup is
automatic on any probe failure or driver unbind. This also allows
removing the manual err label and the .remove callback.

Subject: [PATCH 3449/5214] dt-bindings: phy: add support for NXPs TJA1145 CAN
 transceiver

Adding documentation for NXPs TJA1145 CAN transceiver, which resides like
the ti,tcan104x-can.yaml in the same directory as other generic PHY
subsystem bindings. At the moment there is only support for simple PHYs
by using regulator bindings in combination with can-transceiver.yaml or
PHYs that implement the generic PHY subsystem like the NXP TJA1145.

Subject: [PATCH 3451/5214] phy: Move MODULE_DEVICE_TABLE next to the table
 itself

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it
exports, because this is easier to read and verify.  It also makes more
sense since #ifdef for ACPI or OF could hide both of them.

Most of the privers already have this correctly placed, so adjust
the missing ones.  No functional impact.

Some IdeaPad Slim 3 devices and similar with AMD CPUs have a
nonfunctional keyboard and lid switch after s2idle.

It helps to delay suspend by 2.5 seconds so the EC has some time
to do whatever it needs to get done before suspend - unfortunately
at least on my 16ABR8 waking it with a timer (wakealarm) still
triggers the issue, but at least normal resume via keypress or
lid works fine. On the 14ARP10 wakealarm has been reported to also
work fine with this patch.

This issue has been reported for many different devices, this patch
has been tested with the Zen3-based IdeaPad Slim 3 16ABR8 (82XR)
and the Zen3+-based IdeaPad Slim 3 14ARP10 (83K6) and IdeaPad Slim 3
15ARP10 (83MM).

Subject: [PATCH 3455/5214] platform/x86/amd/pmc: Add delay_suspend module
 parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enabling the new delay_suspend module parameter delays suspend for
2.5 seconds which is known to help for some AMD-based Lenovo Laptops
that otherwise failed to send/receive events for key presses or the
lid switch after s2idle. Apparently the EC needs to do some things
in the background before suspend or it gets into a bad state.

There are many reports of AMD-based laptops (mostly but not exclusively
IdeaPads) about similar issues on the web; this parameter gives
affected users an easy way to try out if their issues have the same
root cause and to work around them until their specific device is added
to the quirks list.

The parameter description has a note encouraging users to report
their device so it can be added to the quirks list, inspired by a
similar request in parameter descriptions of the ideapad-laptop module.

The module parameter can be set to "1" to explicitly enable it,
"0" to disable it even on devices that are assumed to be affected,
or -1 (the default) to enable it if the device is assumed to be affected
(according to fwbug_list[])

Subject: [PATCH 3456/5214] platform/x86/amd/pmc: Don't log during intermediate
 wakeups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ECs in the IdeaPads that need the delay_suspend quirk send lots
of messages when charging, which not only causes intermediate wakeups
when suspended, but also prevents the device from reaching the deepest
suspend state.

Because of this amd_pmc_intermediate_wakeup_need_delay() returns false
during intermediate wakeups and amd_pmc_want_suspend_delay() is called.
So far it always logged its "Delaying suspend by 2.5s ..." messages
then, which spams dmesg. This commit makes sure that those messages are
only logged once per suspend.

Subject: [PATCH 3461/5214] fs: efs: remove unneeded debug prints

The current code uses debug prints conditionally compiled with #ifdef
DEBUG.  However, that code, when compiled, causes compiler errors due to
incompatible formatters and undefined variables, notably:

fs/efs/file.c: In function `efs_get_block':
fs/efs/file.c:26:35: error: `block' undeclared (first use in this
function); did you mean `iblock'?
  26 |                         __func__, block, inode->i_blocks, inode->i_size);
     |                                   ^~~~~

and:

fs/efs/file.c: In function `efs_bmap':
./include/linux/kern_levels.h:5:25: error: format `%ld' expects
argument of type `long int', but argument 4 has type `blkcnt_t' {aka
`long long unsigned int'} [-Werror=format=]
   5 | #define KERN_SOH        "\001"          /* ASCII Start Of Header */
     |                         ^~~~~~

which also extends to the other formatters.  As this part of the code has
been dead for just about 14 years now, it has not been modernized to stay
compatible with the most recent gcc compilers.  Fix these issues by
removing the debug prints.

Subject: [PATCH 3462/5214] lib/test_firmware: allocate the configured into_buf
 size

The batched into_buf test path allocates TEST_FIRMWARE_BUF_SIZE bytes
unconditionally, but then passes test_fw_config->buf_size to
request_firmware_into_buf() or request_partial_firmware_into_buf().

Userspace can set config_buf_size above TEST_FIRMWARE_BUF_SIZE before
triggering a batched request. If the firmware file is large enough, the
firmware loader writes past the end of the 1 KiB test buffer.

Allocate the buffer with the same size that the test passes to the firmware
API so config_buf_size remains the actual buffer size under test.

Subject: [PATCH 3463/5214] Input: ipaq-micro-keys - fix potential deadlock

The driver acquires the micro->lock spinlock in process context (in
micro_key_start() and micro_key_stop()) without disabling interrupts.
However, this lock is also acquired in hardirq context by the MFD core
rx handler (micro_rx_msg()) which is called from the serial ISR.

This can lead to a lock inversion deadlock if the interrupt fires on the
same CPU while the process context holds the lock.

Fix this by using guard(spinlock_irq) instead of guard(spinlock) in
micro_key_start() and micro_key_stop() to disable interrupts while
holding the lock.

The driver accesses the message payload (msg[0]) without checking if
the length is greater than zero. The parent MFD driver can produce a

or stale.

Add a check to return early if len is less than 1.

 NULL dereference when no RAS DES capability

dwc_pcie_rasdes_debugfs_init() returns success when the controller has no
RAS DES capability, leaving pci->debugfs->rasdes_info unset. The common
debugfs teardown path still calls dwc_pcie_rasdes_debugfs_deinit(), which
dereferences rasdes_info unconditionally.

Return early when no RAS DES state was allocated. In that case no RAS DES
mutex was initialized, so there is nothing to destroy.

Subject: [PATCH 3468/5214] perf stat: Fix false NMI watchdog warning in
 aggregation modes

In aggregation modes (e.g. --per-socket, --per-die, etc.), a counter
might not be scheduled or counted on specific aggregate groups if it was
not assigned to the CPUs belonging to those groups. However, the
printout() check triggers the "print_free_counters_hint" logic
unconditionally for any supported counter with a missing count. This
results in a false "Some events weren't counted. Try disabling the NMI
watchdog" warning.

Furthermore, the NMI watchdog only reserves performance counters on core
PMUs. Uncore PMU events (e.g. CHA, IMC) are not affected by the NMI
watchdog, but their failures also falsely triggered this warning.

This warning was originally introduced in commit 02d492e5dcb72c00 ("perf
stat: Issue a HW watchdog disable hint")

To fix this, restrict setting of print_free_counters_hint to only
trigger for core PMU events by checking counter->pmu and
counter->pmu->is_core.

Example before/after:

$ perf stat -M lpm_miss_lat --metric-only --per-socket -a -- sleep 1

Before:

 Performance counter stats for 'system wide':

       ns  lpm_miss_lat_rem ns  lpm_miss_lat_loc
S0      126                202.3               207.9
S1      126                231.9               259.3

       1.006029831 seconds time elapsed

Some events weren't counted. Try disabling the NMI watchdog:
        echo 0 > /proc/sys/kernel/nmi_watchdog
        perf stat ...
        echo 1 > /proc/sys/kernel/nmi_watchdog

After:

Subject: [PATCH 3470/5214] cxl/test: Add check after kzalloc() memory in
 alloc_mock_res()

alloc_mock_res() calls kzalloc() without checking the return value.
Add scope based resource management to deal with the allocated memory
cleanly.

Subject: [PATCH 3471/5214] Input: rmi4 - fix register descriptor address
 calculation

When reading the register descriptor, the base address is incremented by
1 to read the presence register block. However, after reading the
presence register block, the address is incorrectly incremented by only
1 byte (++addr) instead of the actual size of the presence block
(size_presence_reg). This causes the subsequent structure block read to
read from the wrong memory location if the presence block is larger than
1 byte.

Fix this by advancing the address by size_presence_reg.

Subject: [PATCH 3473/5214] Input: rmi4 - fix type overflow in register counts

The number of registers in the RMI4 register descriptor is populated
by counting the bits in the presence map using bitmap_weight(). Since
the presence map can contain up to 256 bits (RMI_REG_DESC_PRESENSE_BITS),
storing this count in a u8 can overflow to 0 if all 256 bits are set.

Change the num_registers field in struct rmi_register_descriptor
from u8 to u16 to prevent potential integer overflow and ensure safe
processing of devices reporting large descriptors.

Subject: [PATCH 3475/5214] Input: rmi4 - initialize attn_fifo properly

attn_fifo is allocated as part of struct rmi_driver_data using
devm_kzalloc in rmi_driver_probe. However, it is never initialized.
A zero-initialized kfifo has its mask set to 0, which effectively
limits its capacity to 1 element instead of the declared 16.
This can lead to lost attention data and memory leaks of the attention
data payload if multiple attention events are received before the
threaded interrupt handler can process them.

Initialize attn_fifo using INIT_KFIFO after allocating rmi_driver_data.

Subject: [PATCH 3478/5214] Input: rmi4 - fix bit count in bitmap_copy()

bitmap_copy() takes number of bits, not bytes (or longs). Correct
the bit count in rmi_driver_set_irq_bits() and
rmi_driver_clear_irq_bits().

Subject: [PATCH 3480/5214] Input: rmi4 - use local presence map in
 rmi_read_register_desc()

The presence map is only used during the parsing of the register
descriptor, so we can make it a local variable instead of storing it
in struct rmi_register_descriptor.

Also fix the spelling of the constant and the variable name (presence
instead of presense).

Subject: [PATCH 3481/5214] Input: rmi4 - refactor function allocation and
 registration

Currently, rmi_create_function() allocates memory for the rmi_function
structure, but rmi_register_function() initializes the device via
device_initialize(). This split of ownership makes error handling in
rmi_create_function() confusing because the caller must be aware that
if rmi_register_function() fails, it has already called put_device() to
clean up the memory.

To make the memory lifecycle explicit and fix potential leaks cleanly
introduce rmi_alloc_function() to handle memory allocation and device
initialization, and make the caller of rmi_register_function()
responsible for cleanup.

Subject: [PATCH 3484/5214] Input: rmi4 - change reg_size type to u32

Change reg_size from unsigned long to u32 to save space and ensure
consistent size across 32-bit and 64-bit architectures, and use
DECLARE_BITMAP() for subpacket_map.

Also pack the structure by rearranging the members to avoid holes,
and use size_add() to prevent potential integer overflows when
calculating the total size of registers.

Subject: [PATCH 3485/5214] Input: rmi4 - use unaligned access helpers in F12

Use get_unaligned_le16() instead of manual bit shifts to construct
16-bit values for max_x, max_y, pitch_x, pitch_y, and object
coordinates in the F12 parsing logic. This simplifies the code and
makes the endianness explicit.

Subject: [PATCH 3487/5214] Input: rmi4 - use devm_kmalloc for F12 data packet
 buffer

The sensor->data_pkt buffer is used exclusively to store incoming
hardware data during the attention handler, where it is entirely
overwritten by either memcpy() or rmi_read_block(). Therefore,
there is no need to zero-initialize it during probe.

Switch to devm_kmalloc() to avoid the unnecessary memset overhead.

 sensor tuning

Propagate the actual error code returned by rmi_read() in
rmi_f12_read_sensor_tuning() instead of hardcoding -ENODEV.
Also, since rmi_read() returns 0 on success, use 'if (ret)'
instead of 'if (ret < 0)'.

Subject: [PATCH 3492/5214] xfrm: use compat translator only for u64 alignment
 mismatch

The XFRM compat layer (CONFIG_XFRM_USER_COMPAT) translates 32-bit xfrm
netlink and setsockopt messages into the native 64-bit layout. It is
only needed on architectures where the 32-bit and 64-bit ABIs disagree
on u64 alignment, which the kernel encodes as COMPAT_FOR_U64_ALIGNMENT.

That symbol is defined only by arch/x86. XFRM_USER_COMPAT depends on it,
so the translator can never be built on any other architecture,
including arm64, which still provides a 32-bit compat ABI (CONFIG_COMPAT)
for AArch32 EL0 userspace. On arm64 the AArch32 EABI already aligns u64
to 8 bytes, identical to the AArch64 ABI, so no translation is required
and the native code path is correct for 32-bit tasks.

However, xfrm_user_rcv_msg() and xfrm_user_policy() gate on
in_compat_syscall() alone and then call xfrm_get_translator(), which
returns NULL when no translator is registered. On arm64 that is always
the case, so every xfrm netlink message and the XFRM_POLICY setsockopt
issued by a 32-bit task returns -EOPNOTSUPP. A 32-bit userspace process
on arm64 (and on any other arch with CONFIG_COMPAT but without
COMPAT_FOR_U64_ALIGNMENT) therefore cannot configure XFRM state or
policy through the XFRM_USER netlink API, and cannot use the XFRM_POLICY
setsockopt path, because both fail before reaching the native parser.

The translator series replaced the blanket compat rejection with a
translator lookup. That made the path usable on x86 when the translator
is available, but left architectures that cannot build the translator
permanently rejected even when their compat layout already matches the
native layout. Let those architectures use the native parser instead.

Gate the translator requirement on COMPAT_FOR_U64_ALIGNMENT instead of
on in_compat_syscall() alone. Gating on the ABI property rather than on
CONFIG_XFRM_USER_COMPAT is deliberate: on x86 with IA32_EMULATION=y but
XFRM_USER_COMPAT=n, a 32-bit task must still be rejected rather than
routed through the native parser, which would misread genuinely
4-byte-aligned x86-32 messages. COMPAT_FOR_U64_ALIGNMENT is the ABI
property that makes the XFRM translator mandatory.

Only the receive/input direction needs the guard. The send, dump and
notification paths already call the translator as "if (xtr) { ... }"
with no error on NULL, so on arches without a translator they no-op and
the kernel emits native 64-bit-layout messages, which is what an AArch32
task expects.

Tested on Juniper SRX hardware: with the fix, 32-bit IPsec userspace
netlink and XFRM_POLICY setsockopt operations that previously failed
with -EOPNOTSUPP now succeed; x86 behaviour is unchanged by inspection.

Subject: [PATCH 3493/5214] net: af_key: initialize alg_key_len for IPComp
 states

pfkey_msg2xfrm_state() handles the IPComp (SADB_X_SATYPE_IPCOMP) case by
allocating x->calg and copying only the algorithm name:

	x->calg = kmalloc_obj(*x->calg);
	if (!x->calg) {
		err = -ENOMEM;
		goto out;
	}
	strcpy(x->calg->alg_name, a->name);
	x->props.calgo = sa->sadb_sa_encrypt;

Unlike the authentication (x->aalg) and encryption (x->ealg) branches of
the same function, the compression branch never initializes
calg->alg_key_len.  IPComp carries no key and the allocation only
reserves sizeof(struct xfrm_algo) (i.e. no room for a key), so the field
is left containing uninitialized slab data.

calg->alg_key_len is later used as a length by xfrm_algo_clone() when an
IPComp state is cloned during XFRM_MSG_MIGRATE:

	xfrm_state_migrate()
	  xfrm_state_clone_and_setup()
	    x->calg = xfrm_algo_clone(orig->calg);
	      kmemdup(orig, xfrm_alg_len(orig));

where xfrm_alg_len() returns sizeof(*alg) + (alg_key_len + 7) / 8.  With
a non-zero garbage alg_key_len, kmemdup() reads past the end of the
68-byte calg object.  Adding an IPComp SA via PF_KEY and then migrating
it triggers (net-next, KASAN, init_on_alloc=0):

  The buggy address belongs to the object at ff11000025a74980
   which belongs to the cache kmalloc-96 of size 96
  The buggy address is located 0 bytes inside of
   allocated 68-byte region [ff11000025a74980, ff11000025a749c4)

Depending on the uninitialized value the same field can instead request
an oversized kmemdup() allocation and make the migration clone fail.

The XFRM netlink path is not affected: verify_one_alg() rejects an
XFRMA_ALG_COMP attribute shorter than xfrm_alg_len(), so a calg added via
XFRM_MSG_NEWSA is always self-consistent.

Initialize calg->alg_key_len to 0, matching the aalg/ealg branches.

Subject: [PATCH 3494/5214] xfrm: Fix dev use-after-free in xfrm async
 resumption

xfrm async resumption hold skb->dev refcnt until after transport_finish.
However, xfrm_rcv_cb may modify skb->dev to tunnel dev without taking
device reference, such as vti_rcv_cb. The subsequent async resumption
will decrement the tunnel device's reference count, which lead to uaf
of tunnel dev and refcnt leak of orig dev as below:

unregister_netdevice: waiting for vti1 to become free. Usage count = -2

Stash the original skb->dev to fix refcnt imbalance. The new skb->dev set
by xfrm_rcv_cb can race with device teardown. Extend rcu protection over
xfrm_rcv_cb and transport_finish to prevent races.

Subject: [PATCH 3496/5214] KVM: x86: remove nested_mmu from mmu_is_nested()

nested_mmu is always stored into vcpu->arch.walk_mmu at the same time as
guest_mmu is stored into vcpu->arch.mmu.  But nested_mmu is not even
a proper MMU, it is only used for page walking; plus the fact that
walk_mmu has to be switched at all is just an implementation detail.

In the end what matters here is whether the guest is using nested
page tables; vmx/nested.c and svm/nested.c check it to see if they
are in nEPT or nNPT context respectively.  So switch to checking
root_mmu vs. guest_mmu, which is a more cogent test.

Subject: [PATCH 3497/5214] KVM: nVMX: remove unnecessary code in
 prepare_vmcs02_rare

The early vmwrite of the PDPTRs in prepare_vmcs02_rare() is redundant, because
every write it does will be performed by prepare_vmcs02() if it is actually
needed.

In any case where the emulator or the processor need the PDPTR, either
is_pae_paging() is true on vmentry, or a write of CR0, CR4 or EFER will
cause a vmexit to L0.  The next vmentry will refresh the PDPTRs in the
vmcs02 from vmcs12.

In fact, the original version[1] of what ended up being commit
c7554efc8335 ("KVM: nVMX: Copy PDPTRs to/from vmcs12 only when
necessary"), the writes in what is now prepare_vmcs02_rare() were removed.
When the mega-collection of optimizations was posted[2], the removal of
that code got dropped as a rebase good, so reinstate it.

Subject: [PATCH 3498/5214] KVM: nSVM: invalidate cached PDPTRs across nested
 NPT transitions

When L2 runs under nested NPT and uses PAE paging, KVM's cached PDPTRs
in mmu->pdptrs[] can hold stale or wrong values after nested
transitions and across migration restore, because both
nested_svm_load_cr3() and svm_get_nested_state_pages() only refresh
PDPTRs on the !nested_npt path.

The user-visible bug is on migration restore of an L2 running with nested
NPT and 32-bit PAE paging, if userspace uses KVM_SET_SREGS rather than
KVM_SET_SREGS2.  In that case, load_pdptrs() leaves VCPU_EXREG_PDPTR
marked as available, and kvm_pdptr_read() will use a stale translation
that used L1 GPAs instead of L2 nGPAs.  svm_get_nested_state_pages()
runs on first KVM_RUN but skips the refresh because nested_npt_enabled()
is true.  The CPU itself reads L2's PDPTRs correctly from memory via
L1's NPT, but KVM-side walking of guest PAE page tables uses the bogus
cached values.

Unlike Intel's GUEST_PDPTR0..3 fields in the VMCS, SVM has no
VMCB-cached PDPTR state: the in-memory PDPTEs at the current CR3 are
the only source of truth, and svm_cache_reg(VCPU_EXREG_PDPTR) simply
reloads them from memory via load_pdptrs().  Clearing the avail
bit (and the dirty bit because !avail/dirty is invalid) to force
a reload when PDPTRs as needed fixes the bug.

Do the same for nested_svm_load_cr3()'s nested_npt branch, so that
the invariant "PDPTRs need reloading" is handled similarly for both
immediate and deferred loading.

Subject: [PATCH 3499/5214] KVM: x86: check that kvm_handle_invpcid is only
 invoked with shadow paging

This is true for both Intel and AMD.  On Intel, "enable INVPCID" is
set unconditionally if supported, but the vmexit is triggered by the
"INVLPG exiting" control which is disabled by enable_ept.  On AMD, KVM
can intercept INVPCID if NPT is enabled but only in order to inject #UD
in the guest.

Subject: [PATCH 3500/5214] KVM: x86/mmu: move pdptrs out of the MMU

PDPTRs are part of the CPU state.  A bit unconventionally, they are
reached via vcpu->arch.walk_mmu instead of being stored in vcpu->arch
directly.  That is nice in principle---it would allow TDP shadow paging
to have its own PDPTRs---but it is not necessary, because EPT has no
PDPTRs and NPT does not cache them.

Since kvm_pdptr_read does not otherwise need the MMU, drop the pdptrs
from the MMU altogether.  There is however something to be careful
about, in that PDPTRs are now not stored separately in root_mmu and
nested_mmu for L1 and L2 guests.  In practice this was already not
an issue:

- for EPT the VMCS0x has to keep them up to date; and for the purpose
  of emulation they are always loaded from the VMCS on vmentry/vmexit,
  thanks to the clearing of dirty and available register bitmaps in
  vmx_switch_vmcs()

- for NPT, VCPU_EXREG_PDPTR is similarly cleared for nNPT, which does
  not cache the PDPTRs; while for non-nNPT the PDPTRs are loaded
  together with the load of CR3.

Note that page table PDPTRs are not affected, since they are stored
in pae_root.

Subject: [PATCH 3501/5214] serial: qcom_geni: Fix RX DMA stall when
 SE_DMA_RX_LEN_IN is zero

In qcom_geni_serial_handle_rx_dma(), geni_se_rx_dma_unprep() clears
port->rx_dma_addr before SE_DMA_RX_LEN_IN is read. If the register is zero,
for example when the RX stale counter fires on an idle line, the handler
returns without calling geni_se_rx_dma_prep().

The next RX DMA interrupt then hits the !port->rx_dma_addr guard and
returns immediately, so the RX DMA buffer is never rearmed and later input
is lost.

Keep the handler on the rearm path when rx_in is zero. Warn about the
unexpected zero-length DMA completion, skip received-data handling, and
always call geni_se_rx_dma_prep().

Subject: [PATCH 3502/5214] vc_screen: fix null-ptr-deref in vcs_notifier()
 during concurrent vcs_write

A KASAN null-ptr-deref was observed in vcs_notifier():

BUG: KASAN: null-ptr-deref in vcs_notifier+0x98/0x130
Read of size 2 at addr qmp_cmd_name: qmp_capabilities, arguments: {}

The issue is a race condition in vcs_write(). When the console_lock is
temporarily dropped (to copy data from userspace), the vc_data pointer
obtained from vcs_vc() may become stale. After re-acquiring the lock,
vcs_vc() is called again to re-validate the pointer. If the vc has been
deallocated in the meantime, vcs_vc() returns NULL, and the while loop
breaks (with written > 0). However, after the loop, vcs_scr_updated(vc)
is still called with the now-NULL vc pointer, leading to a null pointer
dereference in the notifier chain (vcs_notifier dereferences param->vc).

Fix this by adding a NULL check for vc before calling vcs_scr_updated().

 to pci_device_id members
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PCI_VDEVICE macro assigns 0 to .class and .class_mask to allow the
next value in the initializer to define the value for .driver_data.

So the construct

	{
		PCI_VDEVICE(INTASHIELD, 0x0D21),
		.class = PCI_CLASS_COMMUNICATION_MULTISERIAL << 8,
		.class_mask = 0xffff00,
		.driver_data = pbn_b2_4_115200,
	},

introduced in commit 44e55f1f3088 ("serial: 8250_pci: Consistently
define pci_device_ids using named initializers") has conflicting
assignments. In only some configurations (i.e. W=1 for me) that makes
the compiler unhappy.

So convert the two affected items to PCI_DEVICE which doesn't have that
hidden assigment to .class and .class_mask.

Subject: [PATCH 3506/5214] sparc32: remove deadwood swift_flush_tlb_page()
 debug code

Remove an #if 0 block that has been dead since at least
Linux 2.6.12.  The block was marked "P3: deadwood to debug
precise flushes on Swift" and contained a never-compiled
alternative implementation of swift_flush_tlb_page().  It also
referenced the since-removed srmmu_flush_tlb_page(), dropped
in commit 3d5f7d37c8b4 ("sparc32: drop unused functions in
pgtsrmmu.h").

Subject: [PATCH 3510/5214] sparc: Avoid -Wunused-but-set-parameter in
 clear_user_page()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The loop in clear_user_pages() iterates over all pages and calls
clear_user_page() for each of them. During the loop "vaddr" is modified.
However on sparc clear_user() is a macro which does not use "vaddr".
The compiler sees a variable which is modified but never used and emits
a warning for that:

	include/linux/highmem.h: In function 'clear_user_pages':
	include/linux/highmem.h:234:63: warning: parameter 'vaddr' set but not used [-Wunused-but-set-parameter=]
		static inline void clear_user_pages(void *addr, unsigned long vaddr,

Other architectures use an inline function for clear_user_page() which
avoids the warning. This is not possible on sparc, as
sparc_flush_page_to_ram() is not yet declared where clear_user_page() is
defined. Including cacheflush_32.h will trigger recursive and lots of
other issues.

So hide the warning with a cast to (void) instead.

While we are here, do the same for copy_user_page().

Fixes: 62a9f5a85b98 ("mm: introduce clear_pages() and clear_user_pages()")

Subject: [PATCH 3511/5214] platform/x86/amd/hsmp: Clamp ioctl/send_message
 indices (Spectre v1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Although validate_message() checks msg_id, a mispredicted branch can
still allow speculative indexing into hsmp_msg_desc_table[]. Clamp
msg.msg_id with array_index_nospec() at entry to hsmp_ioctl_msg() so
downstream dereferences (including via is_get_msg() and
hsmp_send_message()) see a bounded index.

Similarly, hsmp_send_message() bounds-checks msg->sock_ind before
indexing hsmp_pdev.sock[], but a mispredicted branch can still
speculatively use the raw index (Spectre v1, CVE-2017-5753). Apply
array_index_nospec() after the check so every caller that reaches
hsmp_pdev.sock[] through this helper sees a clamped socket
index—including hsmp_ioctl_msg() and any other path that hands a
user-derived struct hsmp_message to hsmp_send_message().

The functions class_register()/_unregister() and device_create()
both support taking a const pointer to the class struct. Use this
to mark wmi_bus_class as const so that it can be placed into
read-only memory for better security.

Subject: [PATCH 3522/5214] platform/wmi: Make sysfs attributes const
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sysfs core supports const attributes. Use this to mark all
sysfs attributes as const so that they can be placed into read-only
memory for better security.

Subject: [PATCH 3523/5214] modpost: Handle malformed WMI GUID strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some WMI GUIDs found inside binary MOF files contain both
uppercase and lowercase characters. Blindly copying such
GUIDs will prevent the associated WMI driver from loading
automatically because the WMI GUID found inside WMI device ids
always contains uppercase characters.

Avoid this issue by always converting WMI GUID strings to
uppercase. Also verify that the WMI GUID string actually looks
like a valid GUID.

Subject: [PATCH 3524/5214] KVM: s390: Minor refactor of base/ext facility
 lists

Directly use the size of the arrays instead of going through the
indirection of kvm_s390_fac_size().
Don't use magic number for the number of entries in the non hypervisor
managed facility bit mask list.
Make the constraint of that number on kvm_s390_fac_base obvious.
Get rid of implicit double anding of stfle_fac_list.

Subject: [PATCH 3528/5214] cxl: Align interleave decode/encode helpers with
 their callers

The interleave conversion helpers translate between encoded HDM
interleave values and the granularity and way values used by the
driver.

These helpers have been a recurring source of static analysis
complaints that expose type mismatches and potentially uninitialized
outputs. Fix those issues in the helpers so callers inherit the
consistent behavior automatically.

The decode and encode helpers have different interface issues.

The decode helpers return values through unsigned int pointers, but
the decoded values are ultimately represented as int throughout the
driver. Align the helper interfaces with their callers by changing
the out-parameters to int * and updating the handful of affected
locals to match.

The encode helpers leave their out-parameters unchanged on error. That
means callers that ignore the return value may observe uninitialized
encoded values. Initialize the outputs so failed conversions leave
defined values. This issue was originally reported by Purva and the
helper-side fix was suggested by Dan [1].

Tidy up a related, pre-existing, printk format specifier mismatch in
cxl_validate_translation_params().

No functional change for valid interleave parameters.

Subject: [PATCH 3529/5214] tools/testing/cxl: Resolve auto-region decoder
 targets like real HW

The mock auto-region created at module load wrote switch and host-bridge
decoder target[] directly, in addition to target_map[]. Real HW programs
only target_map[] and resolves target[] as dports enumerate, via
update_decoder_targets(). Region replay already follows that ordering,
the initial auto-region did not.

Drop the direct target[] writes and call
cxl_port_update_decoder_targets() so target[] is resolved the same way
as real HW and region replay, exercising more of the auto-region driver
path.

This is inspired by the discussion [1] below:

Subject: [PATCH 3530/5214] cxl/region: Fix out-of-bounds access in
 cxl_cancel_auto_attach()

In cxl_cancel_auto_attach(), it assumes cxled->pos is a valid index for
accessing p->targets[]. However, cxled->pos can be set to negative errno
in cxl_region_sort_targets() if cxl_calc_interleave_pos() fails. This
causes the driver to use a negative index to access p->targets[],
resulting in out-of-bounds access.

Fix it by walking p->targets[] instead of using cxled->pos directly.

Subject: [PATCH 3531/5214] cxl/region: Fill first free targets[] slot during
 auto-discovery

Any invalid endpoint decoder pointer in the target array of an active
region is not allowed by cxl driver. This means cxl driver always
assumes the first p->nr_targets entries of the target array in an
auto-assembly region are valid. However, there are scenarios that could
leave NULL endpoint decoder pointer holes in the target array.

1. When cxl_cancel_auto_attach() removes an endpoint decoder from a
   target array, the target slot is set to NULL. If the removed endpoint
   decoder is not the last element in the target array, the target array
   will contain a NULL hole.

2. When a auto-assembly region removes an assigned endpoint decoder, if
   the removed endpoint decoder is not the last element in the target
   array, always remains a NULL hole in the target array.

When a NULL pointer hole exists in a region's target array, it
introduces two potential problems:
1. Access an endpoint decoder via a NULL pointer. it always trigger
   calltrace like that.

2. Not having enough valid endpoint decoders attached to an
   auto-assembly region. if an auto-assembly region is created with lock
   flag or assigned endpoint decoder with lock flag, which means
   assigned endpoint decoder will not be reset during detaching, they
   could re-attach to the auto-assembly region again. But cxl region
   driver relies on p->nr_targets to verify whether the required number
   of endpoint decoders has been attached, and NULL endpoint decoder
   pointers are still counted in that case.

To fix above issues, adjust cxl_region_attach_auto() logic to find the
first free target slot for endpoint decoder attachment, this ensures
NULL holes in the target array are filled, rather than adding new
endpoint decoders at the tail of the target array.

Subject: [PATCH 3532/5214] usb: ucsi: huawei_gaokun: support mode switching

The USB PHY (QMP Combo PHY) is always initialized in USB3+DP mode. In
the past, there was no MUX, and it was unnecessary to set it, since
MSM only supported 2-lane DP. But now, MST and 4-lane DP support has
been added to MSM, and a MUX has been added to the PHY. To support
4-lane DP and mode switching for gaokun, get the MUX and set it.

Subject: [PATCH 3533/5214] KVM: selftests: access_tracking_perf_test: bump
 number of NUMA nodes to 32

It's rare to find a system that has more than 4 sockets,
but a system can have more than 4 NUMA nodes if each socket
exposes its chiplets as separate NUMA nodes.

In particular, our CI caught a failure in this test on a system with
two sockets, each containing an 'AMD EPYC 7601 32-Core Processor'.

Bump the limit to 32, just in case.

Subject: [PATCH 3534/5214] cxl/region: Block region delete during region
 creation

Expand the range lock, rename it "regions_lock", to disable region deletion
in the critical period between construct_region() and attach_target(), as
well as the period between device_add() and registering the remove actions.

Otherwise, userspace can confuse the kernel. It can violate the assumption
the region stays registered through the completion of cxl_add_to_region().
It can violate the assumption that devm_add_action_or_reset() is working
with a live 'struct cxl_region'.

It is ok for the region to disappear outside of those windows as that
mirrors device hotplug flows where the proper locks are held.

Subject: [PATCH 3535/5214] cxl/region: Resolve region deletion races

Sungwoo noticed that the sysfs trigger to delete a region may try to delete
a region multiple times. It also has no exclusion relative to the kernel
releasing the region via CXL root device teardown.

Instead of installing new cxl root devres actions per region, use the
existing root decoder unregistration event to remove all remaining regions.
An xarray of regions replaces a devres list of regions.

This handles 3 separate issues with the old approach:

1/ sysfs users racing to delete the same region: no longer possible now
   that the regions_lock is held over the lookup and deletion.

2/ multiple actions triggering deletion of the same region: solved by
   erasing regions while holding @regions_lock, and only proceeding on
   successful erasure.

3/ userspace racing devres_release_all() to trigger the devres not found
   warning: solved by sysfs unregistration not requiring a release action

Subject: [PATCH 3537/5214] cxl/memdev: Introduce cxl_class_memdev_type

In preparation for memdev's without mailbox related infrastructure,
introduce cxl_class_memdev_type as a superset of a cxl_memdev_type.
Effectively the only difference is that cxl_class_memdev_type exports
common sysfs attributes where cxl_memdev_type has none.

Related to this is all the cxl_mem_probe() paths that assume the presence
of a class device mailbox are updated to skip that requirement.

Subject: [PATCH 3538/5214] cxl/region: Introduce devm_cxl_probe_mem()

To date, platform firmware maps accelerator memory and accelerator drivers
simply want an address range that they can map themselves. This typically
results in a single region being auto-assembled upon registration of a
memory device.  Use the @attach mechanism of devm_cxl_add_memdev()
parameter to retrieve that region while also adhering to CXL subsystem
locking and lifetime rules. As part of adhering to current object lifetime
rules, if the region or the CXL port topology is invalidated, the CXL core
arranges for the accelertor driver to be detached as well.

The locking and lifetime rules were validated with Dave's work-in-progress
cxl-type-2 support for cxl_test.

devm_cxl_add_classdev() supports the general memory expansion flow where
region assembly is optional, dynamic, and user controlled.

In is_full_charged(), power_supply_get_by_name() is called to
obtain a reference to the fuel_gauge power supply. If the
voltage check (uV >= desc->fullbatt_uV) succeeds, the function
returns true directly without releasing the reference, leaking
the refcount.

Fix this by setting a flag and jumping to the out label where
power_supply_put() properly drops the reference.

The affected pinctrl drivers either check for the presence of a standard

Using boolean or u32 helpers for those cases disagrees with the binding.

Use a presence helper for "gpio-ranges" and read
"microchip,spi-present-mask" with the u8 helper documented by the
binding.

A later change will make list_for_each_entry() cache the next element

newly discovered child nodes to the temporary walk list while the list is
being traversed.

Keep the loop open-coded so the next node is looked up only after
children have been appended. This preserves the current breadth-first
traversal semantics and prepares the code for the list iterator update.

Subject: [PATCH 3545/5214] batman-adv: gw: don't deselect gateway with active
 hardif

The batadv_hardif_cnt() was previously checking if there is an
batadv_hard_iface->mesh_iface which is has the same mesh_iface. And since
batadv_hardif_disable_interface() was resetting the
batadv_hard_iface->mesh_iface after this check, it had to verify whether
*1* interface was still part of the mesh_iface before it started the
gateway deselection.

But after batadv_hardif_cnt() is now checking the lower interfaces of
mesh_iface and batadv_hardif_disable_interface() already removed the
interface via netdev_upper_dev_unlink() earlier in this function, the check
must now make sure that *0* interfaces can be found by batadv_hardif_cnt()
before selected gateway must be deselected. Otherwise the deselection would
already happen one batadv_hard_iface too early.

Because a 0 hardif count from batadv_hardif_cnt() is equal to an empty
list, it is possible to replace the counting with a simple list_empty().

Subject: [PATCH 3546/5214] batman-adv: ensure bcast is writable before
 modifying TTL

Before batman-adv is allowed to write to an skb, it either has to have its
own copy of the skb or used skb_cow() to ensure that the data part is not
shared.

The old implementation used a shared queue and created copies before
attempting to write to it. But with the new implementation, the broadcast
packet is already modified when it gets received. Potentially writing to
shared buffers in this process.

Adding a skb_cow() right before this operation avoids this and can at the
same time prepare it for the modifications required to rebroadcast the

Subject: [PATCH 3547/5214] batman-adv: fix (m|b)cast csum after decrementing
 TTL

The broadcast and multicast packets can be received at the same time by the
local system and forwarded to other nodes. Both are simply decrementing the
TTL at the beginning of the receive path - independent of chosen paths
(receive/forward). But such a modification of the data conflicts with the
hw csum. This is not a problem when the packet is directly forwarded but
can cause errors in the local receive path.

Such a problem can then trigger a "hw csum failure". The receiver path must
therefore ensure that the csum is fixed for each modification of the
payload before batadv_interface_rx() is reached.

Since all batman-adv packet types with a ttl have it as u8 at offset 2, a
helper can be used for all of them. But it is only used at the moment for
batadv_bcast_packet and batadv_mcast_packet because they are the only ones
which deliver the packet locally but unconditionally modify the TTL.

Subject: [PATCH 3548/5214] batman-adv: frag: ensure fragment is writable
 before modifying TTL

Before batman-adv is allowed to write to an skb, it either has to have its
own copy of the skb or use skb_cow() to ensure that the data part is not
shared. But batadv_frag_skb_fwd() modifies the TTL even when it is shared.

Adding a skb_cow() right before this operation avoids this and can at the
same time prepare it for the modifications required to forward the
fragment.

Subject: [PATCH 3549/5214] batman-adv: frag: avoid underflow of TTL

Packets with a TTL are using it to limit the amount of time this packet can
be forwarded. But for batadv_frag_packet, the TTL was always only reduced
but it was never evaluated. It could even underflow without any effect.

Check the TTL in batadv_frag_skb_fwd() before attempting to prepare it for
forwarding. This keeps it in sync with the not fragmented unicast packet.

Subject: [PATCH 3550/5214] batman-adv: v: prevent OGM aggregation on disabled
 hardif

When an interface gets disabled, the worker is correctly disabled by
batadv_hardif_disable_interface() -> ... -> batadv_v_ogm_iface_disable().
In this process, the skb aggr_list is also freed.

But batadv_v_ogm_send_meshif() can still queue new skbs (via
batadv_v_ogm_queue_on_if()) to the aggr_list. This will only stop after all
cores can no longer find the RCU protected list of hard interfaces. These
queued skbs will never be freed or consumed by batadv_v_ogm_aggr_work.

The batadv_v_ogm_iface_disable() function must block
batadv_v_ogm_queue_on_if() to avoid leak of skbs.

Subject: [PATCH 3551/5214] batman-adv: tp_meter: restrict number of unacked
 list entries

When the unacked_list is unbound, an attacker could send messages with
small lengths and appropriated seqno + gaps to force the receiver to
allocate more and more unacked_list entries. And the end either causing an
out-of-memory situation or increase the management overhead for the (large)
list that significant portions of CPU cycles are wasted in searching
through the list.

When limiting the list to a specific number, it is important to still
correctly add a new entry to the list. But if the list became larger than
the limit, the last entry of the list (with the highest seqno) must be
dropped to still allow the earlier seqnos to finish and therefore to
continue the process. Otherwise, the process might get stuck with too high
seqnos which are not handled by batadv_tp_ack_unordered().

Subject: [PATCH 3553/5214] batman-adv: tp_meter: prevent parallel
 modifications of last_recv

When last_recv is updated to store the last receive sequence number, it is
assuming that nothing is modifying in parallel while:

* check for outdated packets is done
* out of order check is performed (and packets are stored in out-of-order
  queue)
* the out-of-order queue was searched for closed gaps
* sequence number for next ack is calculated

Nothing of that was actually protected. It could therefore happen that the
last_recv was updated multiple times in parallel and the final sequence
number was calculated with deltas which had no connection to the sequence
number they were added to.

Lock this whole region with the same lock which was already used to protect
the unacked (out-of-order) list.

Subject: [PATCH 3554/5214] batman-adv: tp_meter: handle overlapping packets

If the size of the packets would change during the transmission, it could
happen that some retries of packets are overlapping. In this case, precise
comparisons of sequence numbers by the receiver would be wrong. It is then
necessary to check if the start sequence number to the end sequence number
("seqno + length") would contain a new range.

If this is the case then this is enough to accept this packet. In all other
cases, the packet still has to be dropped (and not acked).

Subject: [PATCH 3556/5214] Revert "PCI/MSI: Unmap MSI-X region on error"

This reverts commit 1a8d4c6ecb4c81261bcdf13556abd4a958eca202.

Commit 1a8d4c6ecb4c ("PCI/MSI: Unmap MSI-X region on error") added an
iounmap(dev->msix_base) on the error path of msix_capability_init() to
release the MSI-X region when msix_setup_interrupts() fails.

When msix_setup_interrupts() fails, the call chain is:

  msix_setup_interrupts()
    -> __msix_setup_interrupts()
         struct pci_dev *dev __free(free_msi_irqs) = __dev;
         ...
         return ret;  // __free cleanup fires on error

The __free(free_msi_irqs) cleanup calls pci_free_msi_irqs(), which
already handles the unmap:

  void pci_free_msi_irqs(struct pci_dev *dev)
  {
      pci_msi_teardown_msi_irqs(dev);
      if (dev->msix_base) {
          iounmap(dev->msix_base);   // already unmapped here
          dev->msix_base = NULL;     // and set to NULL
      }
  }

So dev->msix_base is unmapped and set to NULL before
msix_setup_interrupts() returns to msix_capability_init(). The
"goto out_unmap" introduced by commit 1a8d4c6ecb4c ("PCI/MSI: Unmap
MSI-X region on error") then calls iounmap() a second time on a NULL
pointer.

This was reproduced on Intel Emerald Rapids (192 CPUs) while
running tools/testing/selftests/kexec/test_kexec_jump.sh:

  WARNING: CPU#44 at iounmap+0x2a/0xe0
  RIP: 0010:iounmap+0x2a/0xe0
  RDI: 0000000000000000
  Call Trace:
   msix_capability_init+0x317/0x3f0
   __pci_enable_msix_range+0x21d/0x2c0
   pci_alloc_irq_vectors_affinity+0xa9/0x130
   nvme_setup_io_queues+0x2a8/0x420 [nvme]
   nvme_reset_work+0x151/0x340 [nvme]
   ...

RDI=0 confirms iounmap() is called with NULL.

Restore the original "goto out_disable" and leave the unmap to the
existing __free(free_msi_irqs) cleanup.

Subject: [PATCH 3557/5214] landlock: Set audit_net.sk for socket access checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Set audit_net.sk in current_check_access_socket() to provide the socket
object to audit_log_lsm_data().  This makes Landlock consistent with
AppArmor, which always sets .sk for socket operations, and with
SELinux's generic socket permission checks.

The socket's local and foreign address information (laddr, lport, faddr,
fport) is logged by the shared lsm_audit.c infrastructure when the
socket has bound or connected state.  Fields with zero values are
suppressed by print_ipv4_addr()/print_ipv6_addr(), so the audit output
is unchanged for the common case of bind denials on unbound sockets.
For connect denials after a prior bind, the bound local address (laddr,
lport) appears before the existing sockaddr fields (daddr, dest).

No existing fields are removed or reordered, and the new field names
(laddr, lport, faddr, fport) are standard audit fields already emitted
by other LSMs through the same lsm_audit.c code path.

Add a connect_tcp_bound audit test that binds to an allowed port and
then connects to a denied one, verifying that the denial record reports
laddr/lport from the bound socket in addition to the connect
destination.

Subject: [PATCH 3558/5214] landlock: Account all audit data allocations to
 user space
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mark the kzalloc_flex() of struct landlock_details with
GFP_KERNEL_ACCOUNT so the allocation is charged to the calling task,
like the other Landlock per-domain allocations which have used
GFP_KERNEL_ACCOUNT forever.

Every property of landlock_details is caller-attributable: allocated by
landlock_restrict_self(2), owned by the caller's landlock_hierarchy,
contents are the caller's pid, uid, comm, and exe_path, lifetime bounded
by the caller's domain.  While the caller may not know nor control the
size of this allocation (i.e. exe_path), this data should still be
accounted for it.

The deciding factor is whether userspace can trigger the allocation, not
whether the size of the data is known nor controlled by the caller.
This aligns with the kmemcg accounting policy established by commit
5d097056c9a0 ("kmemcg: account certain kmem allocations to memcg").

No new failure modes: the hierarchy and ruleset are allocated before
details and are already accounted, so landlock_restrict_self(2) already
returns -ENOMEM under memcg pressure.  This change widens that existing
failure window slightly; it does not introduce a new error code.

Subject: [PATCH 3559/5214] landlock: Demonstrate best-effort allowed_access
 filtering
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Landlock provides best-effort sandboxing across ABI versions:
applications request the rights they need, and on older kernels the
unsupported rights are silently dropped from handled_access_* by the
documented compatibility switch.  The recommended pattern for
landlock_add_rule(2) calls is to mirror this filtering at the rule
level, which wasn't explicitly described in the exemple.

Show the pattern explicitly in the filesystem and network rule examples
by masking each rule's allowed_access against the ruleset's
handled_access_* and adding the rule only when at least one bit remains
set.  This makes the recommended best-effort pattern self-documenting.

Subject: [PATCH 3560/5214] landlock: Fix LANDLOCK_SCOPE_SIGNAL bypass on the
 SIGIO path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

LANDLOCK_SCOPE_SIGNAL must prevent a sandboxed process from signaling
processes outside its Landlock domain.  It can be bypassed through the
asynchronous SIGIO delivery path.

A sandboxed process that owns any file or socket can arm it with
fcntl(fd, F_SETOWN, -pgid), fcntl(fd, F_SETSIG, SIGKILL) and O_ASYNC, so
that an I/O event makes the kernel deliver the chosen signal to the
whole process group.  As the head of its process group's task list (the
default position right after fork()) that group can also hold the
non-sandboxed process that launched it, e.g. a supervisor or a security
monitor.  The sandbox can thus kill or signal the processes
LANDLOCK_SCOPE_SIGNAL is meant to protect from it.

The scope is enforced in hook_file_send_sigiotask() against the Landlock
domain recorded at F_SETOWN time, not the live domain of the sender.
control_current_fowner() decides whether to record that domain and skips
recording it when the fowner target is in the caller's thread group,
which is safe only for a single-task target (PIDTYPE_PID, PIDTYPE_TGID).
For a process group (PIDTYPE_PGID) pid_task() returns only one member;
recording is skipped whenever that member shares the caller's thread
group, and hook_file_send_sigiotask() then lets the signal fan out to
the whole group unchecked.

Record the domain for every non single-process target so the scope is
enforced against each group member at delivery time.

That recording is necessary but not sufficient on its own: the kernel
signals a process group through its members' thread-group leaders, and
the leader of the registrant's own process can carry a different
Landlock domain than the sibling thread that armed the owner.
domain_is_scoped() would then deny that leader, even though commit
18eb75f3af40 ("landlock: Always allow signals between threads of the
same process") requires same-process delivery to be allowed.
hook_task_kill() avoids this by evaluating same_thread_group() live, per
recipient; the SIGIO path instead delegates the whole decision to a
single registration-time check, which a process-group fan-out cannot
honor.

So also record the registrant's thread group next to its domain and
exempt it at delivery: hook_file_send_sigiotask() allows the signal
whenever the recipient belongs to the registrant's own process,
restoring the same-process guarantee while keeping out-of-domain group
members blocked.  The direct kill() path (hook_task_kill) already
evaluates the live domain and is unaffected.

 SIGIO/fowner pgid path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add regression tests for the LANDLOCK_SCOPE_SIGNAL handling of the
asynchronous SIGIO delivery path (fcntl(F_SETOWN)) with a process-group
owner.

sigio_to_pgid_members covers the bypass: a sandboxed process at the head
of its process group's PGID hlist (the default after fork()) arms
F_SETOWN(-pgrp) + O_ASYNC and triggers the fan-out; the in-domain owner
must be signaled (proving the trigger fired) while the non-sandboxed
member of the group, outside the domain, must not.

sigio_to_pgid_self covers the same-process guarantee: the owner is
registered from a sandboxed non-leader thread, whose domain differs from
the thread-group leader the kernel signals for a process-group owner.
That leader belongs to the owner's own process and must still be
signaled.

Without the fix the first test sees the out-of-domain member signaled
and the second sees the owner's own leader denied.

Subject: [PATCH 3562/5214] selftests/landlock: Explicitly disable audit in
 teardowns
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I'm seeing sporadic selftest failures, such as

  #  RUN           scoped_audit.connect_to_child ...
  # scoped_abstract_unix_test.c:314:connect_to_child:Expected 0 (0) == records.access (8)
  # connect_to_child: Test failed
  #          FAIL  scoped_audit.connect_to_child
  not ok 19 scoped_audit.connect_to_child

This seems similar to what commit 3647a4977fb73d ("selftests/landlock:
Drain stale audit records on init") tried to fix. However, the added
drain loop is not effective. When setting the AUDIT_STATUS_PID, the
kauditd_thread is woken up starting to send messages from the hold queue
to the netlink. Depending on scheduling of this kthread not all messages
might be send via the netlink in the 1 us interval.

Therefore, instead of trying to drain the queue, let's just disable
audit when running non-audit tests or more precisely disable it after
audit-tests. This way we won't generate any new audit message that could
interfere with the other tests.

The comment saying that on process exit audit will be disabled is wrong.
The closed file descriptor just causes an auditd_reset(), not a
disablement. So future messages will be queued in the hold queue.

Socket family is read (twice) in a context where the socket is not
locked, so another thread can setsockopt(IPV6_ADDRFORM) to write it
concurrently. Add needed READ_ONCE() annotation.

Use the proper macro to access __sk_common.skc_family like everywhere
else.

Subject: [PATCH 3564/5214] landlock: Add UDP bind() access control
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for a first fine-grained UDP access right.
LANDLOCK_ACCESS_NET_BIND_UDP controls the ability to set the local port
of a UDP socket (via bind()). It will be useful for servers (to start
receiving datagrams), and for some clients that need to use a specific
source port (e.g. mDNS requires to use port 5353)

For obvious performance concerns, access control is only enforced when
configuring sockets, not when using them for common send/recv
operations.

Bump ABI to allow userspace to detect and use this new right.

Subject: [PATCH 3565/5214] landlock: Add UDP send+connect access control
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for a second fine-grained UDP access right.
LANDLOCK_ACCESS_NET_CONNECT_SEND_UDP controls the ability to set the
remote port of a socket (via connect()) and to specify an explicit
destination when sending a datagram, to override any remote peer set on
a UDP socket (e.g. in sendto() or sendmsg()).  It will be useful for
applications that send datagrams, and for some servers too (those
creating per-client sockets, which want to receive traffic only from a
specific address).

Similarly as for bind(), this access control is performed when
configuring sockets, not in hot code paths.

Add detection of when autobind is about to be required, and deny the
operation if the process would not be allowed to call bind(0)
explicitly. Autobind can only be performed in udp_lib_get_port() from
code paths already controlled by LSM hooks: when connect()ing, sending a
first datagram, and in some splice() EOF edge case which, afaiu, can
only happen after a remote peer has been set. This invariant needs to be
preserved to keep bind policies actually enforced.

Subject: [PATCH 3567/5214] selftests/landlock: Add tests for UDP send
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add tests specific to UDP sendmsg() in the protocol_* variants to ensure
behaviour is consistent across AF_INET, AF_INET6 and AF_UNIX.

Subject: [PATCH 3570/5214] apparmor: fix race in unix socket mediation when
 peer_path is used

The holding a reference to the peer_sk is not enough to ensure access
to the peer sk path. Accessing the path outside of the state lock
allows for a race with unix_release_sock(). Fix this by taking the
state lock and getting a reference to the path under lock.

Ideally for connected sockets we would cache this information so we
don't have to take the lock here. But for now just fix the race.

Subject: [PATCH 3571/5214] apparmor: fix refcount leak when updating the
 sk_ctx

Currently update_sk_ctx() transfers the plabel reference, unfortunately
it is also unconditionally put in the caller. Ideally we would make
the caller conditionally put the reference based on whether it was
transferred but for now just fix the bug by getting a reference.

Subject: [PATCH 3572/5214] apparmor: add a conditional version of
 get_newest_label

get_newest_label() will always return a refcount, on the profile it
returns. However there are cases where we only need the refcount
if the label is stale and get_newest_label() will return a different
label.

Optimize this by making the get/put happen conditionally, by keeping
a flag indicating if the get was performed and a put is needed.

Subject: [PATCH 3574/5214] apparmor: check label build before no_new_privs
 test

aa_change_profile() builds a replacement label with
fn_label_build_in_scope() before the no_new_privs subset check. The build
helper can fail and return NULL or an ERR_PTR, but the result was passed
to aa_label_is_unconfined_subset() before the existing IS_ERR_OR_NULL()
check.

Reuse the existing target-label build failure handling immediately after
the build. This preserves the current audit handling while preventing the
subset helper from dereferencing an invalid label.

Subject: [PATCH 3575/5214] apparmor: aa_label_alloc use aa_label_free on alloc
 failure

aa_label_alloc() allocates a secid before allocating or taking the label
proxy. If the later proxy step fails, the error path only freed the label
memory, leaking any resources initialized by aa_label_init().

Use aa_label_free() on the failure path so partially initialized labels
release their secid and other label resources before the backing memory is
freed.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, if the `kvzalloc` in `unpack_table` fails, it returns NULL.
This is masked by `aa_dfa_unpack` which interprets NULL as a -EPROTO,
leading to confusing error messages in `apparmor_parser` [1].

The fixed behavior correctly propagates -ENOMEM on allocation failure.

Subject: [PATCH 3580/5214] apparmor: grab ns lock and refresh when looking up
 changehat child profiles

There was a race condition involving change_hat and profile replacement in
which replacement of the parent profile during a changehat operation could
result in the list of children becoming empty and the changehat operation
failing. To prevent this:
 - grab the namespace lock until we've built the hat transition, and
 - use aa_get_newest_profile to avoid using stale profile objects.

profiles can be pinned by file and other references, and can live long
after they have been replaced/removed. The rawdata however is no longer
needed, and can be freed earlier than the rest of the profile.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The function aa_replace_profiles was accessing udata->size after calling
aa_put_loaddata(udata), causing a potential UAF.

Fixed this by saving the size to a local variable before dropping the
reference.

Subject: [PATCH 3584/5214] apparmor: make fn_label_build() capable of handling
 not supported

Currently fn_label_build() callback fns must provide a transition or
failure. Change this so that a callback can indicate it should be
skipped/not be involved in the label being built.

This will be useful when building object labels based on mediation
flags, as to whether the label should be set.

Existing callers can keep treating NULL return as an error because
none of those callback fns support skipping, but instead of the old
error handling replace with AA_BUG.

Subject: [PATCH 3586/5214] apparmor: remove or add symlinks to rawdata
 according to export_binary

When the export_binary parameter is set, then rawdata is available and
there should be a symbolic link for the rawdata in the profile
directory in apparmorfs. If the parameter is unset, then the symlinks
should not exist.

The issue arises when changing the value of export_binary on runtime
and replacing profiles. If export_binary was set when the profile was
originally loaded, then changed to 0 and the profile was reloaded,
then the symbolic links would still exist but would return ENOENT
because the rawdata no longer exists.

On the opposite side, if export_binary was unset when the profile was
originally loaded, then changed to 1 and the profile was reloaded,
then the symbolic links would not exist, even though the rawdata does.

Subject: [PATCH 3588/5214] apparmor: fail policy unpack on accept2 allocation
 failure

unpack_pdb() may need to allocate a missing ACCEPT2 table for older policy
data. If that allocation failed, it set an error message but jumped to the
success path, returning a policydb with the required table missing.

Return -ENOMEM through the normal failure path when the ACCEPT2 allocation
fails. Remove the now-unused out label.

get_current_exe_path() takes both an exe_file reference and a path

returned immediately and leaked both references.

Route the failure through the common cleanup path so fput() and path_put()
always run after the references are acquired.

Subject: [PATCH 3595/5214] apparmor: Fix inverted comparison in
 cache_hold_inc()

cache_hold_inc() prevents the per-CPU cache hold counter from
rising above MAX_HOLD_COUNT, but the comparison is inverted
(> MAX_HOLD_COUNT instead of <), so the counter never rises
above 0.

This breaks the cache mechanism because since the hold counter
is always 0, the global pool is always attempted first before
falling back to the local cache. The decrement also never occurs,
thus the hold counter is effectively dead.

Fix by changing > to < in cache_hold_inc().

Subject: [PATCH 3596/5214] apparmor: fix use-after-free in rawdata dedup loop

aa_replace_profiles() walks ns->rawdata_list to dedup the incoming
policy blob against entries already attached to existing profiles.
Per the kernel-doc on struct aa_loaddata, list membership does not
hold a reference: profiles hold pcount, and when the last pcount
drops, do_ploaddata_rmfs() is queued on a workqueue that takes
ns->lock and removes the entry. Between dropping the last pcount
and the workqueue running, an entry remains on the list with
pcount == 0.

aa_get_profile_loaddata() is an unconditional kref_get() on
pcount, so when the dedup loop hits such an entry, refcount
hardening reports

  refcount_t: addition on 0; use-after-free.

inside aa_replace_profiles(), and the poisoned counter then
trips "saturated" and "underflow" warnings on the subsequent
uses of the same loaddata.

Before commit a0b7091c4de4 ("apparmor: fix race on rawdata
dereference") the dedup path used a get_unless_zero-style helper
on a single counter, so the existing "if (tmp)" guard was
meaningful. The split-refcount refactor introduced
aa_get_profile_loaddata(), which has plain kref_get() semantics,
and the guard quietly became a no-op.

Introduce aa_get_profile_loaddata_not0(), matching the existing
_not0 convention used by aa_get_profile_not0(), and use it for
the rawdata_list dedup lookup so dying entries are skipped.

Reproduced on x86_64 with v7.1-rc5 in QEMU+KVM running Ubuntu
24.04 + stress-ng 0.17.06:

  stress-ng --apparmor 1 --klog-check --timeout 60s

Without this patch the three refcount_t warnings fire within a
few seconds. With it the same 60 s run is clean. Coverage is a
smoke-test only; a longer soak with CONFIG_KASAN, CONFIG_KCSAN
and CONFIG_PROVE_LOCKING would be welcome from anyone with the
cycles.

Subject: [PATCH 3598/5214] apparmor: replace get_zeroed_page() with kzalloc()

multi_transaction_new() allocates memory with get_zeroed_page() and uses
it as struct multi_transaction.

The usage of that structure does not require struct page access and it is
better to allocate multi_transaction objects with kzalloc() that provides
better scalability and more debugging possibilities.

Replace use of get_zeroed_page() with kzalloc().

Subject: [PATCH 3600/5214] riscv: kvm: Use endian-specific __lelong for NACL
 shared memory

When compiling with sparse enabled (C=2), bitwise type warnings are
triggered in the RISC-V KVM implementation. This occurs because the
user-space data unboxing macro '__get_user_asm' performs implicit
casting on restricted types without forcing the compiler's compliance.

Additionally, raw 'unsigned long *' pointers are used to access the
SBI NACL shared memory, whereas the RISC-V SBI specification mandates
that these structures must follow little-endian byte ordering.

Fix these by:
1. Adding a '__force' cast to '__get_user_asm()' to safely suppress
   implicit cast warnings during user-space data fetching.
2. Introducing the '__lelong' type macro, which dynamically resolves to
   '__le32' or '__le64' depending on XLEN, and replacing 'unsigned long *'
   with '__lelong *' to enforce proper compile-time endianness checks.

Subject: [PATCH 3601/5214] batman-adv: tt: don't merge change entries with
 different VIDs

batadv_tt_local_event() merges/cancels events for the same client which
would conflict or be duplicates. The matching of the queued events only
compares the MAC address - the VLAN ID stored in each event is ignored.

If a MAC would now appear on multiple VID, the two ADD change events (for
VID 1 and VID 2) would be merged to a single vid event. The remote can
therefore not calculate the correct TT table and desync. A full translation
table exchange is required to recover from this state.

A check of VID is therefore necessary to avoid such wrong merges/cancels.

Subject: [PATCH 3603/5214] batman-adv: dat: prevent false sharing between
 VLANs

The local hash of DAT entries is supposed to be VLAN (VID) aware. But
the adding to the hash and the search in the hash were not checking the VID
information of the hash entries. The entries would therefore only be
correctly separated when batadv_hash_dat() didn't select the same buckets
for different VIDs.

Subject: [PATCH 3604/5214] batman-adv: tvlv: enforce 2-byte alignment

The fields of an aggregated OGM(v2) are accessed assuming (at least) 2-byte
alignment, so a following OGM must start at an even offset. As the header
length is even, an odd tvlv_len would misalign it and trigger unaligned
accesses on strict-alignment architectures.

Such a misaligned TVLV/OGM/OGMv2 is not created by a normal participant in
the mesh. Therefore, reject such malformed packets.

Subject: [PATCH 3605/5214] batman-adv: tvlv: avoid race of cifsnotfound
 handler state

TVLV handlers can have the flag BATADV_TVLV_HANDLER_OGM_CIFNOTFND set to
signal that the OGM handler should be called (with NULL for data) when the
specific TVLV container was not found in the OGM. This is used by:

* DAT
* GW
* Multicast (OGM + Tracker)

The state whether the handler was executed was stored in the struct
batadv_tvlv_handler. But the TVLV processing is started without any lock.
Multiple parallel contexts processing TVLVs would therefore overwrite each
others BATADV_TVLV_HANDLER_OGM_CALLED flag in the shared
batadv_tvlv_handler.

Drop the shared BATADV_TVLV_HANDLER_OGM_CALLED flag and instead determine,
per TVLV buffer, whether a matching container was present by scanning the
packet's buffer.

Subject: [PATCH 3606/5214] i3c: mipi-i3c-hci: Fix suspend behavior when bus
 disable falls back to software reset

Software reset was introduced as a fallback if bus disable failed.  The
change was made in 2 places: the cleanup path and the suspend path.

For the cleanup path (i3c_hci_bus_cleanup()), after software reset the
function continues to do cleanup for the current I/O mode.  For the
suspend path (i3c_hci_rpm_suspend()), after software reset the function
returns early.  However software reset does not reset any Ring Headers in
the Host Controller, so returning early is not the right thing to do.

Instead, continue to call suspend for the current I/O mode, which for DMA
mode will reset any Ring Headers.

Note, although Ring Headers should not be active at this stage, performing
this reset follows the procedure defined by the specification and keeps
the suspend path consistent with the cleanup path.

Note also, i3c_hci_sync_irq_inactive() is still called via the PIO and DMA
hci->io->suspend() callbacks.

Always return 0 because the device is quiesced as much as possible and
returning a negative error code would unnecessarily prevent system suspend.

Subject: [PATCH 3607/5214] i3c: mipi-i3c-hci: Preserve RUN bit when aborting
 DMA ring

The MIPI I3C HCI specification does not require the DMA ring RUN bit
(RUN_STOP) to be cleared when issuing an ABORT.  That allows the DMA ring
to continue to receive IBIs, although an IBI is anyway not lost because it
can be received once the ring restarts if the I3C device has not given up.
Note, currently ABORT is only used on a timeout error path so the change
has very little effect in practice.  In the more common case of a transfer
error, the ring (bundle) operation is halted by the controller anyway.

Adjust the RING_CONTROL handling to set ABORT without clearing RUN_STOP,
bringing the driver into alignment with the specification.

Subject: [PATCH 3608/5214] i3c: mipi-i3c-hci: Prevent DMA enqueue while ring
 is aborting or in error

Block the DMA enqueue path while a Ring abort is in progress or after an
error condition has been detected.

Previously, new transfers could be enqueued while the DMA Ring was being
aborted or while error handling was underway. This allowed enqueue and
error-recovery paths to run concurrently, potentially interfering with
each other and corrupting Ring state.

Introduce explicit enqueue blocking and a wait queue to serialize access:
enqueue operations now wait until abort or error handling has completed
before proceeding. Enqueue is unblocked once the Ring is safely restarted.

Note, there is only 1 ring bundle configured, and a transfer error causes
the controller to halt ring (bundle) operation, so there is only ever 1
outstanding error at a time.  Furthermore, a later patch ensures that only
the currently active transfer list can time out.  Consequently, the DMA
queue will not be unblocked while there are outstanding transfer errors or
timeouts.

Subject: [PATCH 3609/5214] i3c: mipi-i3c-hci: Wait for DMA ring restart to
 complete

Although hci_dma_dequeue_xfer() is serialized against itself via
control_mutex, this does not guarantee that a DMA ring restart
triggered by a previous invocation has fully completed.

When the function is called again in rapid succession, the DMA ring may
still be transitioning back to the running state, which may confound or
disrupt further state changes.

Address this by waiting for the DMA ring restart to complete before
continuing.

hci_dma_dequeue_xfer() relies on state normally updated by the DMA

hci_dma_xfer_done() from the dequeue path.

This handles cases where the interrupt handler has not (yet) run.

Subject: [PATCH 3612/5214] i3c: mipi-i3c-hci: Complete transfer lists
 immediately on error

In DMA mode, transfer lists are currently completed only when the final
transfer in the list completes. If an earlier transfer fails, the list is
left incomplete and callers wait until timeout.

There is no need to wait for a timeout, as the completion path in
i3c_hci_process_xfer() already checks for error status. Complete the
transfer list as soon as any transfer in the list reports an error.

This avoids unnecessary delays and spurious timeouts on error.

Complete a transfer list completion immediately there is an error.

Subject: [PATCH 3613/5214] i3c: mipi-i3c-hci: Avoid restarting DMA ring after
 aborting wrong transfer

Software ABORT of the DMA ring is used to recover from transfer list
timeouts, but it is inherently racy.  The intended transfer list may
complete just before the ABORT takes effect, causing the subsequent
transfer list to be aborted instead.

In this case, an incomplete transfer list may remain in the ring and has
not yet been processed by hci_dma_dequeue_xfer().  Restarting the DMA
ring at that point can lead to unpredictable results.

Detect when the next queued transfer is not the first entry of a transfer
list and does not belong to the list currently being dequeued.  In that
case, skip restarting the DMA ring and defer recovery until a subsequent
call to hci_dma_dequeue_xfer(), which will safely restart the ring once
the incomplete list is handled.

Subject: [PATCH 3614/5214] i3c: mipi-i3c-hci: Add DMA ring abort/reset quirk
 for Intel controllers

Some Intel I3C HCI controllers cannot reliably restart a DMA ring after an
ABORT.  Additional queue resets are required to recover, and must be
performed using PIO reset bits even while operating in DMA mode.

This behavior is non-standard.  Introduce a controller quirk to opt into
the required PIO queue resets after a DMA ring abort, and enable it for
Intel LPSS I3C controllers.

Subject: [PATCH 3616/5214] i3c: mipi-i3c-hci: Add DMA ring abort quirk for
 Intel controllers

DMA rings can be aborted either per-ring via RING_CONTROL or globally
via HC_CONTROL_ABORT. The driver currently relies on the per-ring
mechanism.

Some Intel I3C HCI controllers require HC_CONTROL_ABORT to be asserted
before a DMA ring abort is effective.  This behavior is non-standard.
Introduce a controller quirk to select the required abort method and
enable it for Intel LPSS I3C controllers.

This allows the same logic to be reused for recovery paths in subsequent
changes without duplicating suspend/resume handling.

Subject: [PATCH 3618/5214] i3c: mipi-i3c-hci: Add DMA-mode recovery for
 internal controller errors

Handle internal I3C HCI errors when operating in DMA mode by adding a
simple recovery mechanism.

On detection of an internal controller error, mark recovery as needed and
attempt to restore operation by performing a software reset followed by
state restore.  To keep recovery straightforward on this unlikely error
path, all currently queued transfers are terminated and completed with an
error.

This allows the controller to resume operation after internal failures
rather than remaining permanently stuck.

Note, internal errors indicated by INTR_HC_INTERNAL_ERR, cause the
controller to stop.

When a transfer list is only partially completed due to an error,
hci_dma_dequeue_xfer() overwrites the remaining DMA ring entries with
NoOp commands and restarts the ring to flush them out.

While NoOp commands are expected to complete successfully, they may still
fail to complete if the DMA ring is stuck.  Explicitly wait for the NoOp
commands to finish, and trigger controller recovery if they do not
complete or report an error.

This ensures that partially completed transfer lists are reliably
resolved and that a stuck ring is recovered promptly.

Subject: [PATCH 3620/5214] i3c: mipi-i3c-hci: Base timeouts on actual transfer
 start time

Transfer timeouts are currently measured from the point where a transfer
list is queued to the controller.  This can cause transfers to time out
before they have actually started, if earlier queued transfers consume
the timeout interval.

Fix this by recording when a transfer reaches the head of the queue and
adjusting the timeout calculation to start from that point.  The existing
low-overhead completion-based timeout mechanism is preserved, but care is
taken to ensure the transfer start time is consistently recorded for both
PIO and DMA paths.

This prevents premature timeouts while retaining efficient timeout
handling.

Subject: [PATCH 3621/5214] i3c: mipi-i3c-hci: Consolidate DMA ring allocation

dma_alloc_coherent() allocates memory in whole pages, which can waste
space when command and response queues are allocated separately.

Allocate the DMA command and response queues from a single coherent
allocation instead, while preserving the required 4-byte alignment.

This reduces memory overhead without changing behavior.

Subject: [PATCH 3622/5214] i3c: mipi-i3c-hci: Increase DMA transfer ring size
 to maximum

The DMA transfer ring is currently limited to 16 entries, despite the
MIPI I3C HCI supporting up to 32 devices.  When the ring lacks space for a
new transfer list, the driver returns -EBUSY, which can be unexpected
for clients.

Increase the DMA transfer ring size to the maximum supported value of
255 entries.  This effectively eliminates ring-space exhaustion in
practice and avoids the complexity of adding secondary queuing
mechanisms.

Even at the maximum size, the memory overhead remains small
(approximately 24 bytes per entry by default).

Subject: [PATCH 3624/5214] landlock: Add a place for flags to layer rules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To avoid unnecessarily increasing the size of struct landlock_layer, we
make the layer level a u8 and use the space to store the flags struct.

struct layer_access_masks is renamed to struct layer_masks, and a new
field is added to track whether a quiet flag rule is seen for each
layer.  Through use of bitfields, this does not increase the size of the
struct.

From: Tingmao Wang <m@maowtm.org>
Date: Fri, 12 Jun 2026 02:48:48 +0100
Subject: [PATCH 3625/5214] landlock: Add API support and docs for the quiet
 flags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the UAPI for the quiet flags feature (but not the implementation
yet).

Even though currently LANDLOCK_ADD_RULE_QUIET only affects audit
logging, in the future this can also be used as part of a supervisor
mechanism, where it will also suppress denial notifications on a
per-object basis.  Thus the name is deliberately generic, as opposed to
e.g. LANDLOCK_ADD_RULE_LOG_QUIET.

According to pahole, even after adding the struct access_masks
quiet_masks in struct landlock_hierarchy, the u32 log_* bitfield still
only has a size of 2 bytes, so there's minimal wasted space.

+Quiet rule flag (ABI < 10)
+--------------------------
+
+Starting with the Landlock ABI version 10, it is possible to selectively
+suppress logs for specific denied accesses on a per-object basis with
+the ``LANDLOCK_ADD_RULE_QUIET`` flag of sys_landlock_add_rule(), in
+combination with the ``quiet_access_fs`` and ``quiet_access_net`` fields

+logs for scope accesses via the ``quiet_scoped`` field of struct
+landlock_ruleset_attr.  The object is marked as quiet within a ruleset
+when at least one sys_landlock_add_rule() call is made for it with the
+``LANDLOCK_ADD_RULE_QUIET`` flag, additional add-rule calls for the same
+object without this flag do not clear it.

From 5f12f8effb5acb38a8b554ea39bd30d43d54f9f0 Mon Sep 17 00:00:00 2001
From: Tingmao Wang <m@maowtm.org>
Date: Fri, 12 Jun 2026 02:48:49 +0100
Subject: [PATCH 3626/5214] landlock: Suppress logging when quiet flag is
 present
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The quietness behaviour is as documented in the previous patch.

For optional accesses, since the existing deny_masks can only store
2x4bit of layer index, with no way to represent "no layer", we need to
either expand it or have another field to correctly handle quieting of
those.  This commit uses the latter approach - we add another field to
store which optional access (of the 2) are covered by quiet rules in
their respective layers as stored in deny_masks.

From 8faab14922b75c3c0bbc0769eedef85d4609a85a Mon Sep 17 00:00:00 2001
From: Tingmao Wang <m@maowtm.org>
Date: Fri, 12 Jun 2026 02:48:50 +0100
Subject: [PATCH 3627/5214] samples/landlock: Add quiet flag support to
 sandboxer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds ability to set which access bits to quiet via LL_*_QUIET_ACCESS
(FS, NET or SCOPED), and attach quiet flags to individual objects via
LL_*_QUIET for FS and NET.

Subject: [PATCH 3629/5214] selftests/landlock: Add tests for quiet flag with
 fs rules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test various interactions of the quiet flag with filesystem rules:
- Non-optional access (tested with open and rename).
- Optional access (tested with truncate and ioctl).
- Behaviour around mounts matches with normal Landlock rules.
- Behaviour around disconnected directories matches with normal Landlock
  rules (test expected behaviour of 9a868cdbe66a ("landlock: Fix
  handling of disconnected directories") applied to the collected quiet
  flag).
- Multiple layers works as expected.

Subject: [PATCH 3630/5214] selftests/landlock: Add tests for quiet flag with
 net rules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tests that:
- Quiet flag works on network rules
- Quiet flag applied to unrelated ports has no effect
- Denied access not in quiet_access_net is still logged

This is not as thorough as the fs tests, but given the shared logic it
should be sufficient.  There is also no "optional" access for network
rules.

Subject: [PATCH 3633/5214] i3c: master: Make hot-join workqueue freezable to
 block hot-join during suspend

The I3C master workqueue (master->wq) is used to defer work that needs
thread context and the bus maintenance lock, most notably Hot Join
processing (which calls i3c_master_do_daa() to assign dynamic addresses
to newly joined devices).

Currently the workqueue keeps running across system suspend, which can
race with the suspend path:

 - do_daa() may execute after the controller has been suspended,
   issuing bus transactions on a powered-down or otherwise unusable
   controller.
 - New I3C devices can be enumerated and added to the bus mid-suspend,
   registering driver model objects at a point where the I3C subsystem
   and its consumers are not prepared to handle them.

Mark the workqueue WQ_FREEZABLE so its workers are frozen for the
duration of system suspend/hibernate and resumed afterwards. This
naturally defers any pending or newly queued Hot Join work until the
system (and the controller) is fully resumed, closing both races
without adding explicit suspend/resume synchronization in the master
drivers.

Update the kerneldoc for struct i3c_master_controller::wq to reflect
that the workqueue is freezable.

Subject: [PATCH 3634/5214] i3c: master: Serialize i3c_set_hotjoin() with the
 maintenance lock

i3c_set_hotjoin() dispatches the controller's enable_hotjoin() or
disable_hotjoin() op and updates master->hotjoin under
i3c_bus_normaluse_lock(). That lock is a read-side acquisition of
bus->lock (down_read()), so it does not exclude concurrent callers.

The hotjoin sysfs attribute can be opened multiple times, and writes
through different opens are not serialized.  Two concurrent writers
to "hotjoin" can therefore race in i3c_set_hotjoin(), with the
controller op and the master->hotjoin store from one call interleaving
with the other.  The hardware enable/disable state and the value reported
by hotjoin_show() can end up out of sync.

Take i3c_bus_maintenance_lock() instead. Toggling Hot Join enable
changes bus state and is conceptually a maintenance operation, so the
write-side acquisition of bus->lock is the appropriate lock and
serializes concurrent callers against each other and against other
maintenance operations.

Subject: [PATCH 3635/5214] i3c: master: Consolidate Hot-Join DAA work in the
 core

Three master drivers (dw-i3c-master, i3c-master-cdns, svc-i3c-master)
each carry an essentially identical Hot-Join handler: a struct
work_struct embedded in their private state, a work function that just
calls i3c_master_do_daa() on the embedded i3c_master_controller, plus
matching INIT_WORK()/cancel_work_sync() boilerplate in probe/remove (and
shutdown for dw-i3c). The IBI/ISR paths then queue that work onto
master->wq, which already lives in the core.

Move this pattern into the I3C core:

 - Add struct work_struct hj_work to struct i3c_master_controller and
   initialise it in i3c_master_register() with a core-provided handler
   i3c_master_hj_work_fn() that performs i3c_master_do_daa().
 - Cancel the work in i3c_master_unregister() so all controllers get
   correct teardown ordering against the workqueue for free.
 - Export i3c_master_queue_hotjoin() as the single entry point drivers
   call from their Hot-Join IBI handler.

Convert the three existing users to the new API: drop their private
hj_work fields, work functions, INIT_WORK() and cancel_work_sync()
calls, and replace the queue_work(master->wq, &drv->hj_work) call sites
with i3c_master_queue_hotjoin(&drv->base). The dw-i3c shutdown path
still needs to flush pending Hot-Join work before tearing down the
hardware, so it is updated to cancel master->base.hj_work directly.

No functional change intended: the work is still queued on the same
master->wq, runs the same i3c_master_do_daa(), and is cancelled at
controller teardown.  Future Hot-Join improvements now only need to
be made in one place.

Subject: [PATCH 3636/5214] i3c: master: Ensure Hot-Join operations are stopped
 on shutdown

System shutdown invokes each device's bus shutdown callback to quiesce
hardware, but the I3C bus type does not currently implement one.  As a
result, on shutdown the controller's Hot-Join work and any in-flight
i3c_master_do_daa() can keep running (or be newly triggered) while the
rest of the system is being torn down.

A similar window exists at i3c_master_unregister() time: cancel_work_sync()
on hj_work prevents queued work from completing, but does not stop a
fresh Hot-Join IBI from re-queueing the worker, nor a concurrent sysfs
writer from toggling Hot-Join via i3c_set_hotjoin().

Introduce a single "shutting down" gate in the I3C core, set under the
bus maintenance lock so it is observed by any in-progress DAA path
before pending work is cancelled.  Install an i3c_bus_type shutdown
callback that engages this gate for master devices during system
shutdown, and use the same gate in i3c_master_unregister() so both
paths get identical guarantees.

Once the gate is engaged, the Hot-Join worker, i3c_master_do_daa_ext()
and i3c_set_hotjoin() all bail out cleanly, so Hot-Join IBIs that race
with shutdown become no-ops, direct DAA callers see -ENODEV, and sysfs
writers can no longer re-enable Hot-Join through ops->enable_hotjoin()
while the controller is going away.

No functional change for the steady-state runtime path; the new checks
only take effect once the controller has been marked as shutting down.

Note, this patch depends on patch "i3c: master: Consolidate Hot-Join DAA
work in the core".

Subject: [PATCH 3637/5214] i3c: dw: Drop redundant Hot-Join cancel_work_sync()
 in shutdown

The I3C core now installs an i3c_bus_type shutdown callback that
flushes master->hj_work (via i3c_master_shutdown()) before any driver's
platform shutdown hook runs. The explicit cancel_work_sync() in
dw_i3c_shutdown() is therefore redundant: by the time it executes, the
Hot-Join worker has already been cancelled, and the shutting_down gate
makes a new worker a no-op.

Remove the now-unneeded call. No functional change.

Subject: [PATCH 3638/5214] i3c: master: Defer new-device registration out of
 DAA caller context

Master drivers may invoke i3c_master_do_daa_ext() during resume to
re-run Dynamic Address Assignment.  As well as assigning addresses to
any newly arrived devices, this restores the dynamic address of devices
that lost it across system suspend, so it has to run as part of the
controller's resume path.

A side effect of i3c_master_do_daa_ext() today is that it also
registers any newly discovered I3C devices with the driver model
inline, via i3c_master_register_new_i3c_devs().  Doing that from the
resume path is problematic: a hot-join-capable device may join the bus
during this same DAA, and registering it immediately would push driver
model work (probing, sysfs, etc.) into the controller's resume context,
where the rest of the system is not yet fully resumed and the
controller driver is still partway through its own resume sequence.

Decouple discovery from registration: add a reg_work work item to
struct i3c_master_controller and have i3c_master_do_daa_ext() queue it
on master->wq (the freezable workqueue) instead of calling
i3c_master_register_new_i3c_devs() directly.  The worker performs the
registration only when the controller is not shutting_down, and is
cancelled alongside hj_work in i3c_master_shutdown().  Because wq is
freezable, any newly observed devices end up being registered after
the system has finished resuming.

i3c_master_register() also routes its initial post-bus-init registration
through reg_work, using flush_work() to keep probe-time behavior
synchronous.  This keeps a single registration code path and ensures the
worker is the only writer of desc->dev.

Subject: [PATCH 3639/5214] i3c: master: Export i3c_master_enec_disec_locked()

The existing i3c_master_enec_locked() wrapper always treats a NACKed
ENEC CCC as a failure (M2 error).  However, broadcasting ENEC to enable
Hot-Join is legitimately useful even when no I3C devices are currently
present on the bus, in which case the broadcast will be NACKed and
should not be reported as an error.

The underlying helper i3c_master_enec_disec_locked() already accepts a
suppress_m2 flag that lets callers ignore such NACKs.  Expose it so that
a subsequent patch enabling Hot-Join events can issue ENEC with M2
suppression.

Subject: [PATCH 3640/5214] i3c: mipi-i3c-hci: Add Hot-Join support

Wire the MIPI I3C HCI driver into the I3C core Hot-Join framework to
allow targets to dynamically join the bus after initial DAA.

HCI hardware ACKs or NACKs Hot-Join requests based on
HC_CONTROL.HOT_JOIN_CTRL.  This was previously left in the
NACK-and-DISEC state, effectively preventing Hot-Join.  Implement
the ->enable_hotjoin() and ->disable_hotjoin() master operations
so the core and user space can control this policy at runtime.

Also issue broadcast ENEC HJ when enabling Hot-Join.  This is required
because the controller may have previously DISEC'ed the Hot-Join
event, causing targets that were NACKed once to never retry.

Acknowledged Hot-Join requests are delivered as IBIs on the reserved
address 0x02.  Update both the DMA and PIO IBI paths to recognise this
address and forward the event to i3c_master_queue_hotjoin().

To make Hot-Join usable by default, enable it once after the initial
DAA.  This is gated by rpm_ibi_allowed, since otherwise keeping Hot-Join
enabled prevents runtime suspend.  A new hj_init_done flag ensures this
one-time enablement is not repeated on subsequent DAAs.

Subject: [PATCH 3641/5214] i3c: mipi-i3c-hci: Fix race in
 i3c_hci_addr_to_dev()

i3c_hci_addr_to_dev() walks bus->devs.i3c, which is protected by
bus.lock (rwsem).  However, it is invoked from the MIPI I3C HCI IRQ
handler, which cannot take bus.lock.  This allows concurrent device
addition/removal in the I3C core to modify the list while it is being
traversed, potentially leading to use-after-free or crashes.

Remove the dependency on the bus device list and introduce a dedicated
lookup table.  Add an ibi_devs[] array indexed by DAT entry, maintained
under hci->lock.  Update the array when IBIs are enabled or disabled,
so that it always reflects the set of devices allowed to generate IBIs.
Also update when IBIs are freed, to cover the corner case when an IBI is
freed without first being disabled (e.g. oldedev in
i3c_master_add_i3c_dev_locked()).

Move i3c_hci_addr_to_dev() into core.c, reimplement it using the new
array, and add a lockdep assertion to enforce that hci->lock is held
by callers.

Demote a message in PIO and DMA IBI handling, from an error to a debug
message, because there is a race window when the condition can arise
normally.

Subject: [PATCH 3642/5214] i3c: mipi-i3c-hci: Ignore DISEC failures when
 disabling IBIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Disabling IBIs currently returns the result of the DISEC CCC, causing
i3c_hci_disable_ibi() to fail if the transfer errors out.

However, the controller has already been programmed to reject IBIs by
setting DAT_0_SIR_REJECT, so the target’s IBIs are effectively disabled
from the host side regardless of the outcome of the DISEC command.  At
this point, teardown of the IBI infrastructure can safely proceed even
if DISEC fails.

Note, from then on, the MIPI I3C HCI not only NACKs the target's IBI but
automatically sends another DISEC command.

Make i3c_hci_disable_ibi() resilient by ignoring the return value of
i3c_master_disec_locked() and always returning success.

Subject: [PATCH 3643/5214] i3c: master: Prevent reuse of dynamic address on
 device add failure

i3c_master_add_i3c_dev_locked() is called after a device has already
been assigned a dynamic address.  If the function fails, the address
remains marked as free and may be reallocated to another device,
leading to address conflicts on the bus.

Ensure the address is not marked as free on failure, by updating the
address slot state to prevent the address from being re-used.

Emit an error message to inform of the failure.

Opportunistically remove the !master check because it is impossible.

Note, directly resetting the device's dynamic address is no longer
an option, since Direct RSTDAA was deprecated from I3C starting from
version 1.1 and v1.1 (or later) target devices are meant to NACK it.

Subject: [PATCH 3644/5214] i3c: mipi-i3c-hci: Tolerate
 i3c_master_add_i3c_dev_locked() failures in DAA

i3c_master_add_i3c_dev_locked() no longer leaves the address marked as
free on failure, so aborting the DAA sequence on its error is unnecessary.

Failure to register a discovered device does not invalidate the entire
Dynamic Address Assignment (DAA) procedure.  Align with the behavior of
other I3C master drivers by ignoring errors from
i3c_master_add_i3c_dev_locked() and continuing enumeration.

 return void

The return value of i3c_master_add_i3c_dev_locked() is not used by any
caller, and callers are not in a position to recover from failures in
this path.

Change the function to return void.  Amend the kernel-doc accordingly,
fix some grammar and remove a stale paragraph.

Subject: [PATCH 3646/5214] i3c: master: Move DAA API functions after
 i3c_master_add_i3c_dev_locked()

Relocate i3c_master_do_daa_ext() and i3c_master_do_daa() so they appear
after i3c_master_add_i3c_dev_locked().

This ordering is required for upcoming changes where the DAA flow will
(indirectly) rely on i3c_master_add_i3c_dev_locked() functionality.
Reordering avoids forward dependency issues and keeps related code paths
logically arranged.

No functional change.

Subject: [PATCH 3647/5214] i3c: master: Reconcile dynamic addresses after DAA

After Dynamic Address Assignment (DAA), there may be cases where
devices have been assigned dynamic addresses on the bus, but are not
successfully registered in the device model.  This can happen, for
example, if errors occur during device addition, leaving the bus state
and software state inconsistent.

Introduce a reconciliation step to resolve such inconsistencies.

Scan all address slots marked as I3C devices by the bus, and compare
them against the set of devices currently registered.  For any dynamic
address that is marked occupied but has no corresponding i3c_dev_desc,
probe for device presence using a GETSTATUS CCC.

Retry the probe (with exponential backoff delay) to handle transient NACK
conditions.  If a device responds, register it via
i3c_master_add_i3c_dev_locked().  Otherwise, free the address
slot so it may be reused in future DAA operations.

Note, i3c_master_add_i3c_dev_locked() may fail (again), in which case the
dynamic address remains marked as occupied.  A future DAA will try again.

This also handles a corner case where a device is assigned a dynamic
address but not successfully added, and subsequently loses that address
(e.g. due to power management).  If DAA is run again, the device may
receive a new dynamic address while the old one remains marked as
occupied.  Repeated occurrences of this scenario could eventually
exhaust the dynamic address space.  The reconciliation step ensures that
stale addresses are detected and freed, preventing address leakage.

Subject: [PATCH 3648/5214] i3c: Consistently define pci_device_ids using named
 initializers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .driver_data member of the various struct pci_device_id arrays were
initialized by list expressions. This isn't easily readable if you're
not into PCI. Using named initializers is more explicit and thus easier
to parse.

This change doesn't introduce changes to the compiled pci_device_id
arrays. Tested on x86 and arm64.

Add the microchip,sama7d65-i3c-hci compatible string to the MIPI I3C
HCI binding. The Microchip SAMA7D65 I3C controller is based on the
MIPI HCI specification but requires two clocks, so add a conditional
constraint when this compatible is present.

Subject: [PATCH 3651/5214] Input: touchwin - reset the packet index on every
 complete packet

tw_interrupt() accumulates each non-zero serial byte into a fixed
three-byte buffer with a running index that is only reset once a full
packet has been received *and* the device's two Y bytes agree:

	tw->data[tw->idx++] = data;
	if (tw->idx == TW_LENGTH && tw->data[1] == tw->data[2]) {
		...
		tw->idx = 0;
	}

The reset is gated on tw->data[1] == tw->data[2], a value the device
controls.  A malicious, malfunctioning or counterfeit Touchwindow
peripheral can stream non-zero bytes whose 2nd and 3rd bytes differ: the
index reaches TW_LENGTH without the equality holding, is never reset, and
keeps growing, so tw->data[tw->idx++] walks off the end of the three-byte
array and the rest of the heap-allocated struct tw, one attacker-chosen
byte at a time -- an unbounded, device-driven heap out-of-bounds write.

Reset the index on every completed packet and report an event only when
the two Y bytes match, like the other serio touchscreen drivers do.

Subject: [PATCH 3652/5214] platform/x86/intel/pmt: Add pre/post decode hooks
 around header parsing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add optional pre- and post-decode callbacks to the PMT class so namespaces
can perform setup and cleanup steps around header parsing.

  - Add pmt_pre_decode() and pmt_post_decode() to struct
    intel_pmt_namespace.
  - Update intel_pmt_dev_create() to invoke, in order:
      pre → header_decode() → post.
  - Keep the existing pmt_header_decode() callback unchanged.

No functional changes. This adds flexibility for upcoming decoders while
preserving current behavior.

Refactor crashlog initialization to use the PMT namespace pre-decode hook:

  - Add pmt_crashlog_pre_decode() to parse type/version, select the
    crashlog_info, initialize the control mutex, and set entry->attr_grp.
  - Simplify pmt_crashlog_header_decode() to only read header fields from
    the discovery table.
  - Wire the namespace with .pmt_pre_decode = pmt_crashlog_pre_decode.

This separates structural initialization from header parsing, aligning
crashlog with the PMT class pre/post decode flow.

Update the telemetry namespace to use the new PMT class pre/post decode

decode, is now performed in the post-decode hook once header fields are
populated. This preserves existing behavior while reusing the same header
decode logic across PMT drivers.

Subject: [PATCH 3655/5214] platform/x86/intel/pmt: Pass discovery index
 instead of resource
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change PMT class code to pass a discovery index rather than a direct struct
resource when creating entries. This allows the class to identify the
discovery source generically without assuming PCI BAR resources. For PCI
devices, the index still resolves to a resource in the intel_vsec_device.
Other discovery sources, such as ACPI, can use the same index without
needing a struct resource.

Subject: [PATCH 3656/5214] platform/x86/intel/pmt: Cache the telemetry
 discovery header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pmt_telem_header_decode() only needs the discovery header dwords, but it
currently decodes them by reading directly from entry->disc_table.

Cache the discovery header in intel_pmt_entry when the device is created
and have telemetry decode use the cached values instead of performing MMIO
reads at decode time.

The DVSEC discovery resource for a namespace is sized by its per-entry
entry_size (in dwords), which can be less than the 4-dword cache (e.g.
telemetry uses entry_size = 3, i.e. 12 bytes). Cap the memcpy_fromio()
to resource_size(disc_res) so the new cache does not read past the
mapped region. Any unread dwords stay zero from the zero-initialized
allocation of the containing struct.

This keeps the telemetry header decode path independent of how the
discovery data is backed and avoids baking a direct MMIO assumption into
the feature-specific decode logic.

Subject: [PATCH 3657/5214] platform/x86/intel/pmt: Unify header fetch and add
 ACPI source
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Allow the PMT class to read discovery headers from either PCI MMIO or
ACPI-provided entries, depending on the discovery source. The new
source-aware fetch helper caches the canonical discovery header for both
paths, capping PCI MMIO reads to the mapped resource size, while keeping
the mapped PCI discovery table available for users such as crashlog.

Split intel_pmt_populate_entry() into source-specific resolvers:
  - pmt_resolve_access_pci(): handles both ACCESS_LOCAL and ACCESS_BARID
    for PCI-backed devices and sets entry->pcidev. Same existing
    functionality.
  - pmt_resolve_access_acpi(): handles only ACCESS_BARID for ACPI-backed
    devices, rejecting ACCESS_LOCAL which has no valid semantics without
    a physical discovery resource.

This maintains existing PCI behavior and makes no functional changes
for PCI devices.

Subject: [PATCH 3659/5214] platform/x86/intel/pmc: Add ACPI PWRM telemetry
 driver for Nova Lake S
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add an ACPI-based PMC PWRM telemetry driver for Nova Lake S. The driver
locates PMT discovery data in _DSD under the Intel VSEC UUID, parses it,
and registers telemetry regions with the PMT/VSEC framework so PMC
telemetry is exposed via existing PMT interfaces.

Export pmc_parse_telem_dsd() and pmc_find_telem_guid() to support ACPI
discovery in other PMC drivers (e.g., ssram_telemetry) without duplicating
ACPI parsing logic. Also export acpi_disc_t typedef from core.h for callers
to properly declare discovery table arrays.

Selected by INTEL_PMC_CORE. Existing PCI functionality is preserved.

Subject: [PATCH 3660/5214] platform/x86/intel/pmc/ssram: Rename probe and PCI
 ID table for consistency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rename intel_pmc_ssram_telemetry_probe() to pmc_ssram_telemetry_probe() and
intel_pmc_ssram_telemetry_pci_ids[] to pmc_ssram_telemetry_pci_ids[],
updating the MODULE_DEVICE_TABLE() and pci_driver wiring accordingly.

This aligns the symbol names with the driver filename and module name,
reduces redundant intel_ prefixes, and improves readability. No functional
behavior changes are intended.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add per-device platform data for SSRAM telemetry PCI IDs and route probe
through a method selector driven by id->driver_data.

This is a preparatory refactor for follow-on discovery methods while
preserving current behavior: all supported IDs continue to use the PCI
initialization path.

Subject: [PATCH 3662/5214] platform/x86/intel/pmc/ssram: Refactor
 DEVID/PWRMBASE extraction into helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move DEVID/PWRMBASE extraction into pmc_ssram_get_devid_pwrmbase().

This is a preparatory refactor to place functionality in a common helper
for reuse by a subsequent patch. Additionally add missing bits.h
include and define SSRAM_BASE_ADDR_MASK for the address extraction mask.

Subject: [PATCH 3663/5214] platform/x86/intel/pmc/ssram: Switch to static
 array with per-index probe state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace devm-allocated pmc_ssram_telems pointer with a fixed-size static
array and introduce per-index probe state tracking.

This prepares the driver for later per-device probe handling where tying
the PMC tracking storage to one probed PCI device is no longer suitable.

The previous single global device_probed flag cannot describe the state of
individual PMC indices when multiple devices can be probed independently.
Replace it with per-index state (UNPROBED, PROBING, PRESENT, ABSENT) and a
staging cache that publishes discovered values only after probe completes.
This avoids races between probe/unbind and concurrent readers.

Use marked state accesses with release/acquire ordering to prevent compiler
and CPU reordering issues across concurrent probe/unbind cycles.

This patch was substantially rewritten in later revisions. Originally
developed from earlier work by Xi Pardee.

Subject: [PATCH 3664/5214] platform/x86/intel/pmc/ssram: Add ACPI discovery
 scaffolding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prepare the SSRAM telemetry driver for ACPI-based discovery by adding
support for reading telemetry regions from ACPI _DSD properties.

Add pmc_ssram_telemetry_acpi_init() to parse _DSD for telemetry discovery
tables and register them with the Intel VSEC framework. Extend ssram_type
with a p_index field to specify which PMC index each ACPI device owns
(unlike PCI which discovers all three PMCs from one device).

At this stage, no platform IDs are wired to use ACPI discovery - existing
devices continue using the PCI path. Follow-on patches will add platform
support.

Subject: [PATCH 3665/5214] platform/x86/intel/pmc/ssram: Make PMT registration
 optional
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The SSRAM telemetry driver extracts essential PMC device ID and power
management base address information that intel_pmc_core depends on for core
functionality. If PMT registration failure prevents this critical data from
being available, intel_pmc_core operation would break entirely. Therefore,
PMT registration failures must not block access to this data.

Change the behavior to log a warning when PMT registration fails but
continue with successful driver initialization, ensuring the primary
telemetry data remains accessible to dependent drivers.

Subject: [PATCH 3668/5214] accel/ivpu: fix HWS command queue leak on
 registration failure

A command queue is considered valid and usable by the driver only when
it has a doorbell ID assigned (db_id != 0), meaning both the FW cmdq
creation and doorbell registration completed successfully.

However, when either ivpu_register_db() or set_context_sched_properties()
fails after ivpu_hws_cmdq_init() has already created the cmdq in FW,
the command queue is left registered in FW while the driver treats it as
uninitialized (db_id remains 0). On the next submission attempt the
driver tries to register the same cmdq again, which fails because FW
already has an entry for it.

Fix by calling ivpu_jsm_hws_destroy_cmdq() on error paths to properly
unwind FW state and allow subsequent registration attempts to succeed.

Subject: [PATCH 3669/5214] x86/ioperm: Prevent NULL dereference on theoretical
 missing IO bitmap

Outside the IOPL emulation path, the IO bitmap is always expected
to be allocated when TIF_IO_BITMAP is set. The paranoid WARN_ON_ONCE()
handles the case where the flag and the pointer got out of sync.
In this theoretical scenario, which presumes some other bug in the
code that triggers the WARN_ON_ONCe(), return early, instead of
continuing and dereferencing a NULL pointer.

Subject: [PATCH 3670/5214] sparc: Disable compat support with LLD

An LLVM=1 sparc64 allmodconfig enables COMPAT and then tries to
build the 32-bit vDSO. That path cannot be linked with ld.lld:

  ld.lld: error: unknown emulation: elf32_sparc

ld.lld does not support the 32-bit SPARC ELF emulation used for
the compat vDSO, so keep COMPAT disabled when LLD is the linker.
This avoids selecting an unsupported build path while leaving the
existing GNU ld configuration unchanged.

Subject: [PATCH 3671/5214] sparc: Export mcount for Clang-built modules

Clang emits calls to mcount for -pg on sparc64, while the
existing ftrace support only exports the _mcount name. With
FUNCTION_TRACER enabled, modules can therefore keep relocations
against mcount and fail during modpost:

  ERROR: modpost: "mcount" [arch/sparc/kernel/chmc.ko] undefined!

_mcount and mcount are aliases in arch/sparc/lib/mcount.S. Export
the plain mcount alias as well so Clang-built modules can resolve
their profiling call target.

Subject: [PATCH 3672/5214] sparc: led: avoid trimming a newline from empty
 writes

led_proc_write() duplicates up to LED_MAX_LENGTH bytes with
memdup_user_nul() and then unconditionally inspects buf[count - 1] to
strip a trailing newline. A zero-length write therefore reads one byte
before the duplicated buffer.

The previous version rejected empty writes, but empty input already falls
through to the existing default case and turns the LED off like any other
unrecognized string. Preserve that behavior and only skip the newline
trim when there is no input byte to inspect.

Subject: [PATCH 3673/5214] mm/slab: do not init any kfence objects on
 allocation

When init (zeroing) on allocation is requested, for kmalloc() we
generally have to zero the full object size even if a smaller size is
requested, in order to provide krealloc()'s __GFP_ZERO guarantees.

When we end up allocating a kfence object, kfence performs the zeroing
on its own because it has its own redzone beyond the requested size.
Thus slab_post_alloc_hook() has an 'init' parameter which has to be
evaluated in all callers (via slab_want_init_on_alloc()) and should be
false for kfence allocations.

For kfence allocations in slab_alloc_node() this is achieved by subtly
skipping over the slab_want_init_on_alloc() call. Other callers (i.e.
kmem_cache_alloc_bulk_noprof()) however evaluate it unconditionally even
if they do end up with a kfence allocation. This is only subtly not a
problem, as those are not kmalloc allocations and thus the "requested
size" equals s->object_size and thus it cannot interfere with kfence's
redzone. There's just a unnecessary double zeroing (in both kfence and
slab_post_alloc_hook()), but it's all very fragile and contradicts the
comment in kfence_guarded_alloc().

Remove this subtlety and simplify the code by eliminating the init
parameter from slab_post_alloc_hook() and make it call
slab_want_init_on_alloc() itself. Instead add a is_kfence_address()
check before performing the memset, which will start doing the right
thing for all callers of slab_post_alloc_hook().

This potentially adds overhead of the is_kfence_address() check to
allocation hotpath, but that one is designed to be as small as possible,
and it's only evaluated if zeroing is about to happen. This means (aside
from init_on_alloc hardening) only for __GFP_ZERO allocations, and the
zeroing itself comes with an overhead likely larger than the added
check.

While at it, refactor the handling of evaluating when KASAN does the
init instead of SLUB, with no intended functional changes. A
non-functional change is that we don't pass kasan_init as true to
kasan_slab_alloc() if kasan has no integrated init, but then the value
is ignored anyway, so it's theoretically more correct.

Thanks to Harry Yoo for the initial refactoring attempt, and for updated
comments that are used here.

Currently, ath79 SoCs use the default ARCH_DMA_MINALIGN value of 128

Override ARCH_DMA_MINALIGN to use L1_CACHE_BYTES, which is 32 bytes for

Subject: [PATCH 3679/5214] MIPS: mm: Fix out-of-bounds write in
 maar_res_walk()

maar_res_walk() uses wi->num_cfg as the index into the fixed-size
wi->cfg array, but checks whether the array is full only after it has
filled the selected entry. If walk_system_ram_range() reports more than
16 memory ranges, the overflow call writes one struct maar_config past
the end of the array before WARN_ON() prevents num_cfg from advancing.

Move the full-array check before taking the array slot and return non-zero
when the scratch array is full, so walk_system_ram_range() terminates the
walk instead of invoking the callback for further ranges.

Fixes: a5718fe8f70f ("MIPS: mm: Drop boot_mem_map")

Subject: [PATCH 3680/5214] mips: sched: Fix CPUMASK_OFFSTACK memory corruption

This patch addresses a critical memory management flaw. When
CONFIG_CPUMASK_OFFSTACK is enabled, cpumask_var_t is a pointer.
Consequently, sizeof(new_mask) evaluates to the pointer size, causing
copy_from_user() to clobber the mask pointer. Furthermore, the old
logic performed copy_from_user() before allocating the mask.

Fix this by allocating new_mask first. To handle variable-sized user
masks correctly, use cpumask_size() to truncate overly large user masks
or pad undersized masks with zeros before copying the data directly into
the allocated buffer.

Subject: [PATCH 3683/5214] MIPS: smp: report dying CPU to RCU in
 stop_this_cpu()

smp_send_stop() parks all secondary CPUs in stop_this_cpu(). The function
marks the CPU offline for the scheduler via set_cpu_online(false) but
never informs RCU, so RCU keeps expecting a quiescent state from CPUs
that are now spinning forever with interrupts disabled.

As long as nothing waits for an RCU grace period after smp_send_stop()
this is harmless, which is why it went unnoticed. Since commit
91840be8f710 ("irq_work: Fix use-after-free in irq_work_single() on PREEMPT_RT")
however, irq_work_sync() calls synchronize_rcu() on architectures without
an irq_work self-IPI, i.e. where arch_irq_work_has_interrupt() returns
false. That is the asm-generic default used by MIPS. Any irq_work_sync()
issued in the reboot/shutdown path after smp_send_stop() then blocks on
a grace period that can never complete, hanging the reboot:

  WARNING: CPU: 0 PID: 15 at kernel/irq_work.c:144 irq_work_queue_on
  ...
  rcu: INFO: rcu_sched detected stalls on CPUs/tasks:
  rcu: Offline CPU 1 blocking current GP.
  rcu: Offline CPU 2 blocking current GP.
  rcu: Offline CPU 3 blocking current GP.

This issue was noticed on several Realtek MIPS switch SoCs (MIPS
interAptiv) and came up during kernel bump downstream in OpenWrt from
6.18.33 to 6.18.34, after the backport of the patch to the 6.18 stable
branch. The patch also has been backported all the way back to 6.1.

Call rcutree_report_cpu_dead() once interrupts are disabled, mirroring the
generic CPU-hotplug offline path, so RCU stops waiting on the parked CPUs
and grace periods can still complete. MIPS shuts down all CPUs here
without going through the CPU-hotplug mechanism, so this report is not
otherwise issued. Reporting a dying CPU to RCU outside the regular hotplug
offline path is not unprecedented: arm64 does the same in cpu_die_early().
There it is an exception for a CPU that was coming online and is aborting
bringup, rather than the default shutdown action as on MIPS.

Subject: [PATCH 3684/5214] MIPS: VDSO: Avoid including .got in dynamic segment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After commit 2db1ec80dfd5 ("MIPS: VDSO: Fold MIPS_DISABLE_VDSO into
MIPS_GENERIC_GETTIMEOFDAY"), building ARCH=mips allnoconfig with LLVM=1
shows some warnings from llvm-readelf while checking the VDSO for
dynamic relocations:

  llvm-readelf: warning: 'arch/mips/vdso/vdso.so.dbg.raw': invalid PT_DYNAMIC size (0xa4)
  llvm-readelf: warning: 'arch/mips/vdso/vdso.so.dbg.raw': PT_DYNAMIC dynamic table is invalid: SHT_DYNAMIC will be used

The blamed commit alters the link order of objects into vdso.so.raw,
placing vgettimeofday.o after sigreturn.o. This ultimately results in
the .text section shrinking slightly in size, which in turn changes the
offset of the .dynamic section.

  -  [ 9] .text             PROGBITS        000002f0 0002f0 000930 00  AX  0   0 16
  -  [10] .dynamic          DYNAMIC         00000c20 000c20 000090 08   A  5   0  4
  +  [ 9] .text             PROGBITS        000002f0 0002f0 000924 00  AX  0   0 16
  +  [10] .dynamic          DYNAMIC         00000c14 000c14 000090 08   A  5   0  4

Changing the offset of the .dynamic section causes the dynamic segment
size to grow by the same amount, which triggers a warning in
llvm-readelf because PT_DYNAMIC's p_filesz (0xa4) is no longer a
multiple of its sh_entsize (8):

  -  DYNAMIC        0x000c20 0x00000c20 0x00000c20 0x00098 0x00098 R   0x10
  +  DYNAMIC        0x000c14 0x00000c14 0x00000c14 0x000a4 0x000a4 R   0x10

The size of the dynamic segment was already incorrect before the blamed
comment, as it should be 0x90 like the .dynamic section above (18
entries at 8 bytes per entry); it just so happens that 0x98 % 8 is 0,
whereas 0xa4 % 8 is 4, so there was no warning.

Looking at the section to segment mapping of the dynamic segment reveals
that it includes the .got section, as it is implicitly placed after
.dynamic by ld.lld's orphan section heuristics and inherits its segments
from the linker script.

  [ 9] .text             PROGBITS        000002f0 0002f0 000924 00  AX  0   0 16

  [11] .got              PROGBITS        00000cb0 000cb0 000008 00 WAp  0   0 16

    03     .dynamic .got
    04     .note

Explicitly describe the .got section in the MIPS VDSO linker script
after .rodata, which switches back to the default text segment,
resulting in a dynamic segment that is the exact size of the .dynamic
section as expected with no other layout changes.

  -  DYNAMIC        0x000c14 0x00000c14 0x00000c14 0x000a4 0x000a4 R   0x10

Subject: [PATCH 3685/5214] MIPS: lib: Remove '.hidden' for local symbols

After a recent change in binutils that warns when local symbols have
non-default visibility [1], there are a couple instances when building
arch/mips:

  Assembler messages:
  {standard input}: Warning: local symbol `__memset' has non-default visibility
  Assembler messages:
  {standard input}: Warning: local symbol `__memcpy' has non-default visibility

Remove the '.hidden' directives for these symbols to clear up the
warnings, as they are pointless with a local symbol, which is by
definition hidden. This results in no changes to these symbols in nm's
output when assembled with various copies of binutils.

Subject: [PATCH 3686/5214] mips: select legacy gpiolib interfaces where used

A few old machines have not been converted away from the old-style
gpiolib interfaces. Make these select the new CONFIG_GPIOLIB_LEGACY
symbol so the code still works where it is needed but can be left
out otherwise.

This is the list of all gpio_request() calls in mips:

  arch/mips/alchemy/devboards/db1000.c:           gpio_request(19, "sd0_cd");
  arch/mips/alchemy/devboards/db1000.c:           gpio_request(20, "sd1_cd");
  arch/mips/alchemy/devboards/db1200.c:   gpio_request(215, "otg-vbus");
  arch/mips/bcm47xx/workarounds.c:        err = gpio_request_one(usb_power, GPIOF_OUT_INIT_HIGH, "usb_power");
  arch/mips/bcm63xx/boards/board_bcm963xx.c:              gpio_request_one(board.ephy_reset_gpio,
  arch/mips/txx9/rbtx4927/setup.c:        gpio_request(15, "sio-dtr");

Most of these should be easy enough to change to modern gpio descriptors

Subject: [PATCH 3688/5214] ntfs: support following Windows native symlink with
 relative paths

Make ntfs_make_symlink() parse native Windows symbolic link reparse
payloads when the SYMLINK_FLAG_RELATIVE bit is set.
Implement the following changes:
 * Add a dedicated on-disk layout definition for symbolic link reparse
   data.
 * validate the UTF-16 name ranges before decoding them.
 * convert the substitute name into the mount's NLS and normalize path
   separators.

Subject: [PATCH 3689/5214] ntfs: support following Windows native symlink with
 absolute paths

Extend reparse-point handling beyond relative symlinks so NTFS can
expose the Windows absolute forms used by non-relative symbolic links
and junctions.
* Store the reparse tag and symlink flags in the inode.
* Validate junction payloads, and parse targets from substitute_name.
* Add function to rewrite supported Windows absolute path into Linux
  path relative to the mounted NTFS volume.

Subject: [PATCH 3690/5214] ntfs: add native_symlink mount option

Because bind-mounted subtrees of the volume may resolve to unexpected
locations, change converting junctions and non-relative symbolic links
into paths relative to the NTFS volume to be allowed only if the
native_symlink=rel mount option is specified.

Add the native_symlink=<value> mount option to configure how absolute
symbolic links and mount points (junctions) are handled.
The option accepts "raw" or "rel", with "raw" being the default.

Under "raw", the absolute target path (ni->target) is returned as-is
without translation. Under "rel", ntfs_translate_junction() is called
to rewrite the absolute path as a relative path anchored at the volume
root.

Subject: [PATCH 3691/5214] ntfs: clean up target name conversion for WSL
 symlinks

WSL symlink target names are stored as narrow NLS/UTF-8 strings on
disk. Converting the target name to Unicode in ntfs_symlink and
converting it back to NLS in ntfs_reparse_set_wsl_symlink is
redundant.

Remove this conversion and pass the symname directly to the reparse
data setter.

Subject: [PATCH 3694/5214] drm/displayid: fix Tiled Display Topology ID size

The Tiled Display Topology ID of a DisplayID Tiled Display Topology Data
Block consists of three fields:

- Tiled Display Manufacturer/Vendor ID Field (3 bytes)
- Tiled Display Product ID Code Field (2 bytes)
- Tiled Display Serial Number Field (4 bytes)

i.e. a total of 9 bytes, not 8.

The DisplayID Tiled Display Topology ID is used as the tile group
identifier.

Update both struct displayid_tiled_block topology_id member and struct
drm_tile_group group_data member to full 9 bytes.

The group data was missing the last byte of the serial number. I don't
know whether there are known bug reports that might be linked to this,
but it's plausible the last byte could be the differentiating part for
the tile groups, and fewer tile groups might have been created than
intended.

Fixes: b49b55bd4fba ("drm/displayid: add displayid defines and edid extension (v2)")
Fixes: 138f9ebb9755 ("drm: add tile_group support. (v3)")

Subject: [PATCH 3696/5214] powerpc/boot: Allow text relocations for pseries
 wrapper with binutils 2.46+

Binutils 2.46 changed the default linker behavior from '-z notext' to
'-z text', which treats dynamic relocations in read-only segments as
errors rather than warnings. This causes the pseries boot wrapper build
to fail with:

  /usr/bin/ld.bfd: arch/powerpc/boot/wrapper.a(crt0.o): warning:
    relocation against `_platform_stack_top' in read-only section `.text'
  /usr/bin/ld.bfd: error: read-only segment has dynamic relocations

The pseries wrapper uses '-pie' to create position-independent code.
However, crt0.S contains a pointer to '_platform_stack_top' in the .text
section, which requires a dynamic relocation at runtime. This creates
DT_TEXTREL (text relocations), which were allowed by default in binutils
2.45 and earlier (via implicit '-z notext') but are now rejected by
binutils 2.46+.

Add '-z notext' linker flag to explicitly allow text relocations for
the pseries platform, similar to what is already done for the epapr
platform. This restores the previous behavior and allows the boot
wrapper to build successfully with binutils 2.46+.

Subject: [PATCH 3697/5214] exfat: fix handling of damaged volume in
 exfat_create_upcase_table()

When the size of the upcase table is set to zero in the dentry for any
reason(e.g. corrupted media or misbehaving device), an integer overflow
causes the module to loop indefinitely.

If the size of the upcase table is read zero, do not attempt to load the
table. Instead, fallback to loading the default upcase table. If the
size of the upcase table is zero or no upcase table is found, raise
exfat_fs_error() to mark the volume read-only.

Subject: [PATCH 3698/5214] powerpc/perf: fix preempt count underflow in
 fsl_emb_pmu_del

fsl_emb_pmu_del() unconditionally calls put_cpu_var(cpu_hw_events) at
the 'out:' label, but only calls the matching get_cpu_var() after the
'i < 0' early-return check. When event->hw.idx is negative the
function jumps to 'out:' without having taken get_cpu_var(), and the
trailing put_cpu_var() then issues an unmatched preempt_enable(),
underflowing preempt_count.

On a CONFIG_PREEMPT=y kernel preempt_count would underflow and
eventually present as a 'scheduling while atomic' BUG.

Move put_cpu_var() to pair with get_cpu_var() so the percpu access is
correctly bracketed and the 'out:' label only handles perf_pmu_enable.

Subject: [PATCH 3699/5214] powerpc/powernv: fix preempt count leak in
 pnv_kexec_wait_secondaries_down

pnv_kexec_wait_secondaries_down() calls get_cpu() to obtain the current
CPU id but never calls the matching put_cpu(), leaking one
preempt_disable() nesting level on every invocation.

In practice the imbalance does not trigger a visible splat because the
kexec teardown path is a one-way trip: IRQs are already disabled, no
schedule() occurs after the leak, and default_machine_kexec() overwrites
preempt_count with HARDIRQ_OFFSET before jumping into kexec_sequence()
which never returns. However the bookkeeping is still wrong.

The function only needs the current CPU id, and this path runs with
interrupts disabled and the CPU pinned, so the preempt_disable()
side-effect of get_cpu() is unnecessary. Replace it with
raw_smp_processor_id().

Subject: [PATCH 3700/5214] exfat: fix potential use-after-free in
 exfat_find_dir_entry()

In exfat_find_dir_entry(), the buffer_head obtained from
exfat_get_dentry() is released with brelse(bh) before the fall-through
TYPE_EXTEND branch reads the directory entry through ep (which points
into bh->b_data):

	brelse(bh);
	if (entry_type == TYPE_EXTEND) {
		...
		len = exfat_extract_uni_name(ep, entry_uniname);
		...
	}

After brelse() drops our reference, nothing guarantees that the
underlying page backing bh->b_data remains valid for the subsequent
exfat_extract_uni_name() read. This is the same pattern fixed in
commit fc961522ddbd ("exfat: Fix potential use after free in
exfat_load_upcase_table()").

Move brelse(bh) so it runs after ep is no longer dereferenced on
each branch.

Confirmed on QEMU x86_64 with CONFIG_KASAN=y + CONFIG_DEBUG_PAGEALLOC=y
+ CONFIG_PAGE_POISONING=y on linux-next, using a crafted exFAT image
(long filename with same-hash collisions forcing the TYPE_EXTEND path).
With a debug-only invalidate_bdev() inserted between brelse(bh) and
the ep read to make the stale-deref window deterministic, the
unpatched kernel faults:

  BUG: KASAN: use-after-free in exfat_find_dir_entry+0x133b/0x15a0
  BUG: unable to handle page fault for address: ffff88801a5fa0c2
  Oops: 0000 [#1] SMP DEBUG_PAGEALLOC KASAN NOPTI
  RIP: 0010:exfat_find_dir_entry+0x1188/0x15a0

With this patch applied, the same instrumented harness completes
cleanly under the same sanitizer stack. I have not reproduced a
crash on an uninstrumented kernel under ordinary reclaim; the
instrumented A/B establishes the lifetime violation and that the
patch closes it, not an unaided triggerability claim.

Subject: [PATCH 3701/5214] powerpc/kexec: fix double get_cpu() imbalance in
 kexec_prepare_cpus

kexec_prepare_cpus_wait() calls get_cpu() internally to obtain the
current CPU id. kexec_prepare_cpus() calls kexec_prepare_cpus_wait()
twice -- once for KEXEC_STATE_IRQS_OFF and once for
KEXEC_STATE_REAL_MODE -- but only issues a single put_cpu() at the end,
leaving preempt_count elevated by one extra nesting level.

In practice the imbalance does not trigger a 'scheduling while atomic'
splat because the kexec path is a one-way trip: IRQs are already
disabled, no schedule() occurs after the leak, and
default_machine_kexec() overwrites preempt_count with HARDIRQ_OFFSET
before jumping into kexec_sequence() which never returns. However the
bookkeeping is still wrong.

kexec_prepare_cpus() calls local_irq_disable()/hard_irq_disable()
before invoking kexec_prepare_cpus_wait(), so the CPU is already pinned
and the get_cpu()/put_cpu() preempt_disable() bracketing is unnecessary.
Only the current CPU id is needed, so replace get_cpu() with
raw_smp_processor_id() and drop the now-unneeded put_cpu().

Subject: [PATCH 3702/5214] exfat: simplify exfat_lookup()

1) d_splice_alias() handles ERR_PTR() for inode just fine
2) no need to even look for existing aliases in case of directory inodes;
   just punt to d_splice_alias(), it'll do the right thing
3) no need to bother with 'd_unhashed(alias)' case - d_find_alias()
   would've returned that only in case of a directory, and d_splice_alias()
   will handle that just fine on its own.
4) exfat_d_anon_disconn() is entirely pointless now - we only get to
   evaluating it in case dentry->d_parent == alias->d_parent and
   alias being a non-directory.  But in that case IS_ROOT(alias) can't
   possibly be true - that would've reqiured alias == alias->d_parent,
   i.e alias == dentry->d_parent and dentry->d_parent is guaranteed to
   be a directory.  So exfat_d_anon_disconn() would always return false
   when it's called, which makes && !exfat_d_anon_disconn(alias)
   a no-op.

Subject: [PATCH 3703/5214] exfat: replace unsafe macros with static inline
 functions

The current exFAT driver relies on various macros for unit conversions
between clusters, blocks, sectors, and directory entries. These macros
are structurally unsafe as they lack type enforcement and are prone to
potential integer overflows during bit-shift operations, especially
on 64-bit architectures. Replace all arithmetic macros with static inline
functions to provide strict type checking and explicit casting.

Subject: [PATCH 3704/5214] exfat: add balloc parameter to exfat_map_cluster()
 for iomap support

In preparation for supporting the iomap infrastructure, we need to know
whether a new cluster was allocated or not in exfat_map_cluster().

Add an optional 'bool *balloc' output parameter. When a new cluster is
allocated, *balloc is set to true. Pass NULL from exfat_get_block() to
preserve the existing behavior.

Subject: [PATCH 3706/5214] exfat: add support for multi-cluster allocation

Currently exfat_map_cluster() allocates and returns only one cluster
at a time even when more clusters are needed. This causes multiple
FAT walks and repeated allocation calls during large sequential writes
or when using iomap for writes. This change exfat_map_cluster() and
exfat_alloc_cluster() to be able to allocate multiple contiguous
clusters.

Add full buffered I/O support using the iomap framework to the exfat
filesystem. This will replaces the old exfat_get_block(),
exfat_write_begin(), exfat_write_end(), and exfat_block_truncate_page()
with their iomap equivalents. Buffered writes now use
iomap_file_buffered_write(), read uses iomap_bio_read_folio() and
iomap_bio_readahead(), and writeback is handled through iomap_writepages().

Subject: [PATCH 3710/5214] exfat: add iomap direct I/O support

Add iomap-based direct I/O support to the exfat filesystem. This replaces
the previous exfat_direct_IO() implementation that used
blockdev_direct_IO() with iomap_dio_rw() interface.

Subject: [PATCH 3711/5214] exfat: add support for SEEK_HOLE and SEEK_DATA in
 llseek

Adds exfat_file_llseek() that implements these whence values via
the iomap layer (iomap_seek_hole() and iomap_seek_data()) using the
existing exfat_read_iomap_ops.
Unlike many other modern filesystems, exFAT does not support sparse files
with unallocated clusters (holes). In exFAT, clusters are always fully
allocated once they are written or preallocated. In addition, exFAT
maintains a separate "Valid Data Length" (valid_size) that is distinct
from the logical file size. This affects how holes are reported during
seeking. In exfat_iomap_begin(), ranges where the offset is greater
than or equal to ei->valid_size are mapped as IOMAP_UNWRITTEN, while ranges
below valid_size are mapped as IOMAP_MAPPED. This mapping behavior is used
by the iomap seek functions to correctly report SEEK_HOLE and SEEK_DATA
positions.

   - Ranges with offset >= ei->valid_size are mapped as IOMAP_HOLE.
   - Ranges with offset < ei->valid_size are mapped as IOMAP_MAPPED.

Subject: [PATCH 3712/5214] exfat: serialize truncate against in-flight DIO

exfat_setattr() did not call inode_dio_wait() before performing a size
change, leaving a window where a concurrent in-flight DIO write could be
operating on clusters that the truncate is about to free.

Add inode_dio_wait() before the truncate_setsize()/exfat_truncate()
sequence so that any in-flight DIO completes before cluster freeing
begins.

Subject: [PATCH 3713/5214] exfat: preserve benign secondary entries during
 rename and move

Commit 8258ef28001a ("exfat: handle unreconized benign secondary
entries") added cluster freeing for benign secondary entries inside
exfat_remove_entries().  However, exfat_remove_entries() is also called
from the rename and move paths (exfat_rename_file and exfat_move_file),
where the old entry set is being relocated rather than deleted.  This
causes benign secondary entries such as vendor extension entries to be
silently destroyed on rename or cross-directory move, violating the
exFAT spec requirement (section 8.2) that implementations preserve
unrecognized benign secondary entries.

Fix this by adding a free_benign parameter to exfat_remove_entries()
so callers can suppress cluster freeing during relocation, and
extending exfat_init_ext_entry() to copy trailing benign secondary
entries from the old entry set into the new one internally.  Also
clean up the error paths to delete newly allocated entries on failure.

Fixes: 8258ef28001a ("exfat: handle unreconized benign secondary entries")

Subject: [PATCH 3714/5214] exfat: add swap_activate support

Commit 07d67f3e9083 ("exfat: add iomap buffered I/O support")
converted exfat buffered I/O to iomap, but did not add a
.swap_activate handler to the address_space_operations.

swapon(2) on an exfat swapfile then fails with EINVAL, which causes
LTP swap tests to fail.

Add exfat_iomap_swap_activate() and hook it into exfat_aops so exfat
uses iomap_swapfile_activate() for swapfile activation.

Fixes: 614f71ca1bdf ("exfat: add iomap buffered I/O support")

Subject: [PATCH 3715/5214] exfat: bound uniname advance in
 exfat_find_dir_entry()

In exfat_find_dir_entry(), each TYPE_EXTEND (file name) entry advances the
output pointer by a fixed amount while the loop guard only tracks the
accumulated name length:

	if (++order == 2)
		uniname = p_uniname->name;
	else
		uniname += EXFAT_FILE_NAME_LEN;
	len = exfat_extract_uni_name(ep, entry_uniname);
	name_len += len;
	unichar = *(uniname+len);
	*(uniname+len) = 0x0;

uniname grows by EXFAT_FILE_NAME_LEN (15) per name entry, but name_len
grows only by the actual extracted length, which is shorter when a name
fragment contains an early NUL.  The only guard is
`name_len >= MAX_NAME_LENGTH`, so a crafted directory with many short
name fragments lets uniname run far past the
p_uniname->name[MAX_NAME_LENGTH + 3] buffer while name_len stays small,
causing an out-of-bounds read and write at *(uniname+len).

The sibling extractor exfat_get_uniname_from_ext_entry() already stops
on a short fragment (the lockstep `len != EXFAT_FILE_NAME_LEN` guard
added in commit d42334578eba ("exfat: check if filename entries exceeds
max filename length")); exfat_find_dir_entry() never got the
equivalent.  Track the per-entry write offset as a count and reject a
fragment once the offset, or the offset plus the extracted length, would
exceed MAX_NAME_LENGTH, before forming the output pointer.

Subject: [PATCH 3716/5214] mm/slab: introduce slab_alloc_context

Similarly to page allocator's struct alloc_context, introduce a helper
struct to hold a part of the allocation arguments. This will allow
reducing the number of parameters in many functions of the
implementation, and extend them easily if needed.

For now, make it hold the caller address and the originally requested
allocation size.

Convert alloc_single_from_new_slab(), __slab_alloc_node() and
___slab_alloc(). No functional change intended.

Subject: [PATCH 3717/5214] mm/slab: introduce alloc_flags and
 SLAB_ALLOC_NOLOCK

Similarly to the page allocators, introduce slab-allocator specific
alloc flags that internally control allocation behavior in addition to
gfp_flags, without occupying the limited gfp flags space.

Introduce the first flag SLAB_ALLOC_NOLOCK that behaves similarly to
page allocator's ALLOC_TRYLOCK and will be used to reimplement
kmalloc_nolock()'s "!allow_spin" behavior. That currently relies on
gfpflags_allow_spinning() and thus the lack of both __GFP_RECLAIM flags,
importantly __GFP_KSWAPD_RECLAIM. This can give false-positive results
e.g. in early boot with a restricted gfp_allowed_mask.

Also introduce alloc_flags_allow_spinning() to replace the usage of
gfpflags_allow_spinning().

Start using alloc_flags and the new check first in alloc_from_pcs() and
__pcs_replace_empty_main(). This means some slab allocations that were
falsely treated as kmalloc_nolock() due to their gfp flags will now have
higher chances of success, and this will further increase with followup
changes.

Remove a WARN_ON_ONCE() from refill_objects() as it's now legitimate to
reach it from a slab allocation that's not _nolock() and yet lacks
__GFP_KSWAPD_RECLAIM for other reasons.

Subject: [PATCH 3718/5214] mm/slab: replace struct partial_context with
 slab_alloc_context

Refactor get_from_partial_node(), get_from_any_partial(),
get_from_partial() and ___slab_alloc().

Remove struct partial_context, which used to be more substantial but
shrank as part of the sheaves conversion. Instead pass gfp_flags and
pointer to the new slab_alloc_context, which together is a superset of
partial_context, and alloc_flags are about to be added to
slab_alloc_context as well.

No functional change intended.

Subject: [PATCH 3719/5214] mm/slab: add alloc_flags to slab_alloc_context

Add alloc_flags as a new field to the slab_alloc_context helper struct,
so we can pass it to more functions in the slab implementation without
adding another function parameter.

Start checking them via alloc_flags_allow_spinning() in
alloc_single_from_new_slab() (where we can drop the allow_spin
parameter), ___slab_alloc(), get_from_partial_node() and
get_from_any_partial(). This further reduces false-positive
spinning-not-allowed from allocations that are not kmalloc_nolock() but
lack __GFP_RECLAIM flags.

_kmalloc_nolock_noprof() initializes ac.alloc_flags using its flags that
are SLAB_ALLOC_NOLOCK. slab_alloc_node() and __kmem_cache_alloc_bulk()
are not reachable from kmalloc_nolock() and all their callers expect
spinning to be allowed, so they can use SLAB_ALLOC_DEFAULT. This is
temporary as the scope of slab_alloc_context will further move to the
callers, making the alloc_flags usage more obvious.

Also change how trynode_flags are constructed in ___slab_alloc() to
achieve the same "do not upgrade to GFP_NOWAIT" by using masking instead
of checking allow_spin. We need to do that because we now determine
allow_spin from alloc_flags, and would otherwise start to upgrade e.g.
kmalloc() allocations without __GFP_KSWAPD_RECLAIM (that however do
allow spinning) to GFP_NOWAIT, thus including __GFP_KSWAPD_RECLAIM.

During the masking keep also existing __GFP_NOMEMALLOC (pointed out by
Sashiko) and __GFP_ACCOUNT. Previously the hardcoded GFP_NOWAIT would
eliminate them, but it's not a big problem that would need a separate
fix.

Subject: [PATCH 3720/5214] mm/slab: pass alloc_flags to new slab allocation

Add the alloc_flags parameter to allocate_slab() and new_slab()
so it can be used to determine if spinning is allowed, independently
from gfp flags.

refill_objects() passes SLAB_ALLOC_DEFAULT because it can only be
reached from contexts that allow spinning.

Subject: [PATCH 3721/5214] mm/slab: pass alloc_flags through
 slab_post_alloc_hook() chain

Convert the whole following call stack to pass either slab_alloc_context
(thus including alloc_flags) or just alloc_flags as necessary:

slab_post_alloc_hook()
  alloc_tagging_slab_alloc_hook()
    __alloc_tagging_slab_alloc_hook()
      prepare_slab_obj_exts_hook()
        alloc_slab_obj_exts()
  memcg_slab_post_alloc_hook()
    __memcg_slab_post_alloc_hook()
      alloc_slab_obj_exts()

Converting all these at once avoids unnecessary churn and is mostly
mechanical.

This ultimately allows to decide if spinning is allowed using
alloc_flags in alloc_slab_obj_exts(), as well as slab_post_alloc_hook().
Aside from alloc_from_pcs_bulk() (to be handled next) there is nothing
else in slab itself relying on gfpflags_allow_spinning() which can
be false even if not called from kmalloc_nolock().

A followup change will also use the alloc_flags availability in the call
stack above to remove the __GFP_NO_OBJ_EXT flag.

For alloc_slab_obj_exts(), also replace the suboptimal "bool new_slab"
parameter with a SLAB_ALLOC_NEW_SLAB flag with identical functionality.

To further reduce the number of parameters of slab_post_alloc_hook(),
also make 'struct list_lru *lru' (which is NULL for most callers) a new
field of slab_alloc_context.

Subject: [PATCH 3722/5214] mm/slab: replace slab_alloc_node() parameters with
 slab_alloc_context

The function takes all the parameters that exist as fields in
slab_alloc_context, except alloc_flags. Replace them with a single
pointer.

This moves slab_alloc_context initialization to a number of callers,
which is more verbose, but arguably also more clear than a long list of
parameters, and most do not use the 'lru' field.

This will also allow kmalloc_nolock() to call slab_alloc_node() and
reduce the special open-coding it currently has.

Subject: [PATCH 3723/5214] mm/slab: allow kmem_cache_alloc_bulk() with any gfp
 flags

The last user of gfpflags_allow_spinning() in slab is
alloc_from_pcs_bulk(), which is only called from
kmem_cache_alloc_bulk().

It turns out that gfpflags_allow_spinning() is not necessary, because
kmem_cache_alloc_bulk() is only expected to be called from context that
does allow spinning, so simply replace it with 'true'. This means we can
also drop the gfp parameter from alloc_from_pcs_bulk().

With that, we can remove the "@flags must allow spinning" part of the
kernel doc, as there is no more connection to the gfp flags in the slab
implementation.

Also remove a comment in alloc_slab_obj_exts() because there should be
no more false positives possible due to gfp_allowed_mask during early
boot.

Subject: [PATCH 3724/5214] mm/slab: pass slab_alloc_context to
 __do_kmalloc_node()

With alloc_flags usage in slab, we can replace __GFP_NO_OBJ_EXT with an
alloc flag that prevents kmalloc recursion. For that we need a version
of kmalloc() that takes alloc_flags and use it in places that perform
these potentially recursive kmalloc allocations (of sheaves or obj_ext
arrays).

As a preparatory step, make __do_kmalloc_node() take a pointer to
slab_alloc_context. This replaces the 'size' and 'caller' parameters and
includes alloc_flags which we'll make use of.

Subject: [PATCH 3725/5214] mm/slab: allow __GFP_NOMEMALLOC and __GFP_NOWARN
 for kmalloc_nolock()

The two flags are added internally so there's no point for warning if
they are passed by the caller as well, so allow them. This will allow
simplifying obj_ext allocation under kmalloc_nolock().

Also it's not necessary to have the extra alloc_gfp variable for adding
the two flags. The original gfp_flags parameter is not used anywhere
except for the warning. So remove alloc_gfp and directly modify and use
gfp_flags everywhere.

Subject: [PATCH 3726/5214] mm/slab: introduce kmalloc_flags()

With alloc_flags usage in slab, we can replace __GFP_NO_OBJ_EXT with an
alloc flag that prevents kmalloc recursion. For that we need a version
of kmalloc() that takes alloc_flags and use it in places that perform
these potentially recursive kmalloc allocations (of sheaves or obj_ext
arrays).

Add this function, named kmalloc_flags(). Right now it's only useful for
these nested allocations, so it doesn't need to optimize build-time
constant sizes like kmalloc() or kmalloc_buckets.

Since we need it to support both normal and non-spinning
kmalloc_nolock() context through the SLAB_ALLOC_NOLOCK flag, split out
most of the special _kmalloc_nolock_noprof() implementation to
__kmalloc_nolock_noprof() that takes a slab_alloc_context, and make
_kmalloc_nolock_noprof() a simple tail calling wrapper with the proper
context.

kmalloc_flags() can thus determine whether to call
__kmalloc_nolock_noprof() or __do_kmalloc_node(), based on the
given alloc_flags.

Subject: [PATCH 3727/5214] perf maps: Add maps__mutate_mapping

During kernel ELF symbol parsing (dso__process_kernel_symbol), proc
kallsyms image loading (dso__load_kernel_sym,
dso__load_guest_kernel_sym), and dynamic kernel memory map alignment
updates (machine__update_kernel_mmap), the loader directly modifies live
virtual address boundary keys fields on map objects.

If these boundaries are mutated while the map pointer actively resides
inside the parent maps cache array list (kmaps) outside of any lock
closure, an unsafe concurrent window is exposed where parallel worker
lookup threads (e.g., inside perf top) can mistakenly assume the cache
remains sorted based on stale parameters, executing binary search
queries (bsearch) across an unsorted range and triggering lookup
failures.

Fix this by introducing maps__mutate_mapping() that explicitly acquires
the parent maps write semaphore lock, executes an incoming mutation
callback block to perform the field updates under lock protection, and
invalidates the sorted tracking flags prior to releasing the write lock.

This guarantees synchronization invariants, closing the concurrent
lookup race window. The adjacent module alignment pass inside
machine__create_kernel_maps() is safely preserved as a high-performance
lockless pass, as its invocation lifecycle bounds remain strictly
single-threaded by contract during session initialization construction.

To safely support this unconditional down_write write lock mutator
without recursive read-to-write self-deadlock upgrades during lazy
symbol loading, we introduce a public maps__load_maps() API.

It copies map pointers under a brief read lock and force-loads all
modules locklessly outside the lock. Callers (such as perf inject) must
pre-load all kernel symbol maps up front at startup using
maps__load_maps(), completely bypassing dynamic runtime mutations.

Fixes: 39b12f781271 ("perf tools: Make it possible to read object code from vmlinux")

Subject: [PATCH 3728/5214] perf inject/aslr: Add ASLR tool infrastructure and
 MMAP tracking

If perf.data files are taken from one machine to another they may
leak virtual addresses and so weaken ASLR on the machine they are
coming from. Add an aslr option for perf inject that remaps all
virtual addresses, or drops data/events, so that the virtual address
information isn't leaked.

This patch introduces the core ASLR remapping tool infrastructure and
implements remapping/tracking for metadata events (MMAP, MMAP2, COMM,
FORK, EXIT, KSYMBOL, TEXT_POKE). Sample events are delegated without
remapping for now.

Subject: [PATCH 3729/5214] KVM: s390: Add map/unmap ioctl and clean mappings
 post-guest

s390 needs map/unmap ioctls, which map the adapter set
indicator pages, so the pages can be accessed when interrupts are
disabled. The mappings are cleaned up when the guest is removed.
pin_user_pages_remote is used for both the ioctl as well
as the pin-on-demand logic in adapter_indicators_set().

Map/Unmap ioctls are fenced in order to avoid the longterm pinning
in Secure Execution environments. In Secure Execution
environments the path of execution available before this patch is followed.

Statistical counters to count map/unmap functions for adapter indicator
pages are added. The counters can be used to analyze
map/unmap functions in non-Secure Execution environments and similarly
can be used to analyze Secure Execution environments where the counters
will not be incremented as the adapter indicator pages are not mapped.

Subject: [PATCH 3730/5214] KVM: s390: Enable adapter_indicators_set to use
 mapped pages

The s390 adapter_indicators_set function can now be optimized to use
long-term mapped pages when available so that work can be
processed on a fast path when interrupts are disabled.
If adapter indicator pages are not mapped then local mapping is
done on a slow path as it is prior to this patch. For example, Secure
Execution environments will take the local mapping path as it does prior to
this patch.

Subject: [PATCH 3731/5214] KVM: s390: Introducing kvm_arch_set_irq_inatomic
 fast inject

s390 needs a fast path for irq injection, and along those lines we
introduce kvm_arch_set_irq_inatomic. Instead of placing all interrupts on
the global work queue as it does today, this patch provides a fast path for
irq injection.

The inatomic fast path cannot lose control since it is running with
interrupts disabled. This meant making the following changes that exist on
the slow path today. First, the adapter_indicators page needs to be mapped
since it is accessed with interrupts disabled, so we added map/unmap
functions. Second, access to shared resources between the fast and slow
paths needed to be changed from mutex and semaphores to spin_lock's.
Finally, the memory allocation on the slow path utilizes GFP_KERNEL_ACCOUNT
but we had to implement the fast path with GFP_ATOMIC allocation. Each of
these enhancements were required to prevent blocking on the fast inject
path.

Fencing of Fast Inject in Secure Execution environments is enabled in the
patch series by not mapping adapter indicator pages. In Secure Execution
environments the path of execution available before this patch is followed.

Statistical counters have been added to enable analysis of irq injection on
the fast path and slow path including io_390_inatomic, io_flic_inject_airq,
io_set_adapter_int and io_390_inatomic_no_inject. The no inject counter
captures adapter masked, coalesced and suppressed interrupts.

Subject: [PATCH 3732/5214] KEYS: fix overflow in keyctl_pkey_params_get_2()

The length for the internal output buffer is calculated incorrectly, which
can result overflow when a too small buffer is provided.

Fix the bug by allocating internal output with the size of the maximum
length of the cryptographic primitive instead of caller provided size.

Subject: [PATCH 3734/5214] KEYS: trusted: Debugging as a feature

TPM_DEBUG, and other similar flags, are a non-standard way to specify a
feature in Linux kernel. Introduce CONFIG_TRUSTED_KEYS_DEBUG for trusted
keys, and use it to replace these ad-hoc feature flags.

Given that trusted keys debug dumps can contain sensitive data, harden the
feature as follows:

1. In the Kconfig description postulate that pr_debug() statements must be
   used.
2. Use pr_debug() statements in TPM 1.x driver to print the protocol dump.
3. Require trusted.debug=1 on the kernel command line (default: 0) to
   activate dumps at runtime, even when CONFIG_TRUSTED_KEYS_DEBUG=y.

Traces, when actually needed, can be easily enabled by providing
trusted.dyndbg='+p' and trusted.debug=1 in the kernel command-line.

Subject: [PATCH 3737/5214] KEYS: Use acquire when reading state in keyring
 search

The negative-key race fix added release/acquire ordering for key use.

Publish payload before state; read state before payload.

keyring_search_iterator() still uses READ_ONCE() before match callbacks.
An asymmetric match callback calls asymmetric_key_ids(), which reads
key->payload.data[asym_key_ids].

Use key_read_state() there to complete that ordering.

derived_buf is guaranteed to be HASH_SIZE - and it is more than enough.
The strscpy() degenerates into an memcpy() (as did the strcpy()).
Do the same for the associated "ENC_KEY" copy.

Removes a possibly unbounded strcpy().

create auth key
store rka in auth key
wait for helper
                       get auth key
                       load rka from auth key

                       sleep on #PF

helper completed
detach and free rka
destroy auth key
                       wake up
                       use rka->target_key
                       **USE-AFTER-FREE**

Give request_key_auth payloads a refcount.  Take a payload reference while
authkey->sem stabilizes the payload and revocation state.  Hold that
reference across the instantiate and reject paths.  Drop the auth key
owning reference from revoke and destroy.

 concurrency scenario.]

Subject: [PATCH 3745/5214] s390/irq/idle: Use stcke instead of stckf for time
 stamps

The upcoming cpu idle time accounting rework involves comparing and
subtracting cross cpu time stamps. Time stamps created with the stckf
instruction monotonic with respect to the local cpu. For cross cpu
monotonic time stamps the slightly slower stcke instruction has to
be used [1].

Convert the idle time accounting relevant usages of stckf to stcke.

Subject: [PATCH 3746/5214] s390/idle: Provide arch specific
 kcpustat_field_idle()/kcpustat_field_iowait()

The former s390 specific arch_cpu_idle_time() implementation was
removed, since its implementation was racy and reported idle time
could go backwards [1].

However this removal was not necessary, since independently of the s390
architecture specific races there exists the iowait counter update race,
which can also lead to reported idle time going backwards [2].

With Frederic Weisbecker's recent cpu idle time accounting refactoring
kernel_cpustat got a sequence counter. Use this to implement s390 specific
variants of kcpustat_field_idle() and kcpustat_field_iowait(). This is
logically a revert of [1] and moves cpu idle time accounting back into s390
architecture code, which is also more precise than the dyntick idle time
accounting by nohz/scheduler.

For comparing cross cpu time stamps it is necessary to use the stcke
instead of the stckf instruction in irq entry path. Furthermore this
open-codes a sequence lock in assembler and C code, which is required to
update the irq entry time stamp to the per cpu idle_data structure in a
race free manner.

[1] commit be76ea614460 ("s390/idle: remove arch_cpu_idle_time() and corresponding code")
[2] commit ead70b752373 ("timers/nohz: Add a comment about broken iowait counter update race")

Subject: [PATCH 3747/5214] s390/idle: Remove idle time and count sysfs files

Remove the s390 specific idle_time_us and idle_count per cpu sysfs
files. They do not provide any additional value. The risk that there
are existing applications which rely on these architecture specific
files should be very low.

However if it turns out such applications exist, this can be easily
reverted.

Subject: [PATCH 3748/5214] perf inject/aslr: Implement sample address
 remapping

Add the sample address remapping logic to the ASLR tool. This patch
implements aslr_tool__process_sample, which parses sample events,
remaps IPs, ADDRs, callchains, and branch stacks using the mappings
collected from metadata events, and drops potentially leaking raw,
register, stack, physical address, and aux samples.

Also adds the aslr_tool__remap_address helper function.

Note on cross-endian compatibility:
'perf inject' functions as an endianness converter. Input files are read,
and their events are byte-swapped to host endianness in memory. When the
tool emits its output, it writes a host-endian PERF_MAGIC in the file
header, thereby marking the output file as host-endian natively.

Because the output file is always written in host endianness, events and
payloads must be constructed entirely using host-endian layouts. For this
reason, this patch explicitly un-packs and repacks PERF_SAMPLE_TID (and
PERF_SAMPLE_CPU) using unions to ensure that the sequential 32-bit layout
is correctly aligned in host endianness. Similarly, branch stack flags
(which are modified in-place to host-endian bitfields by the parser) are
copied directly to the newly synthesized event. When re-parsing the newly
synthesized event, 'needs_swap=false' is explicitly used to prevent double
swapping the already host-endian fields.

Committer notes:

Removed several unused variables, they will be reintroduced in the
following patches where they are finally used:

	struct aslr_evsel_priv *priv = NULL;
	u64 orig_sample_type;
	u64 orig_regs_user;
	u64 orig_regs_intr;

Also used PRIx64 for two u64 args (addresses) and %zu for a size_t arg
(map__size()) to fix the build on 32-bit architectures.

Subject: [PATCH 3749/5214] perf aslr: Strip sample registers

Extend the ASLR tool stripping helpers to drop register dump payloads
by masking out the relevant perf_event_attr fields (sample_regs_user,
sample_regs_intr) when the delegated tool is handling the data.

struct aslr_evsel_priv maintains the original perf_event_attr values
and is looked up via the evsel_orig_attrs hashmap so that sample sizes
can be properly parsed even when bits are stripped from the pipeline.
This is critical for bounded array copying within aslr_tool__process_sample,
which relies on orig_sample_type to determine exactly which fields were
captured by the kernel before any stripping occurred.

This allows us to keep samples that would otherwise be dropped because
they contain registers, while still obfuscating the registers.

Committer notes:

Moved now used variables from the previous patch:

        struct aslr_evsel_priv *priv = NULL;
        u64 orig_sample_type;
        u64 orig_regs_user;
        u64 orig_regs_intr;

From 190c4546384461f3dee70a649b438aa41c24d01e Mon Sep 17 00:00:00 2001
From: Ian Rogers <irogers@google.com>
Date: Thu, 11 Jun 2026 09:41:22 -0700
Subject: [PATCH 3750/5214] perf test: Add inject ASLR test

Add a new shell test to verify the feature. The test covers:
- Basic address remapping for user space samples.
- Pipe mode coverage for piped into.
- Callchain address remapping.
- Consistency of output before and after injection.
- Pipe mode report consistency.
- Dropping of samples that leak ASLR info (physical addresses).
- Kernel address remapping (utilizing a dedicated kernel-intensive VFS
  dd workload to guarantee continuous timer interrupts sampling flow
  inside kernel privilege states).
- Kernel report consistency with address normalization.

The test suite is hardened with global 'set -o pipefail' assertions
to catch pipeline failures, stream-consuming awk processors to handle
SIGPIPE signals, and a dedicated pipe output scenario validating raw
'perf inject -o -' stdout streams.

Note on kernel DSO normalization in the test script:
The test script deliberately normalizes all kernel DSOs to a generic
[kernel] tag before diffing, as obfuscating physical kernel addresses
forces perf report to occasionally shift samples between individual
modules and [kernel.kallsyms] due to the lack of valid host module
boundary maps.

Note on ARM:
Kernel-based ASLR test cases (test_kernel_aslr and test_kernel_report_aslr)
are skipped on ARM architectures (aarch64 and arm*) to bypass high latency
constraints (such as check_invariants() spending excessive execution time
in maps__split_kallsyms() on debug builds) and symbolization inconsistencies.

From cd355f6dc70503191249c5147e2f2e8f3c8838bd Mon Sep 17 00:00:00 2001
From: Aaron Tomlin <atomlin@atomlin.com>

Subject: [PATCH 3751/5214] perf trace: Fix noise and signed formatting of
 __probe_ip in bare dynamic probes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a dynamic probe is created without explicitly requested arguments
via perf probe --add, the Ftrace subsystem automatically appends
"__probe_ip" to the tracepoint format to record the instruction pointer.

Currently, perf trace prints this implicit field by default.
Furthermore, because the formatting logic defaults to a standard signed
integer representation, the kernel space memory address is erroneously
displayed as a meaningless negative integer.

This patch addresses the user experience by combining two refinements:
    1. "__probe_ip" is now hidden from the standard output, as its
       presence adds no contextual value for a bare probe.

    2. If the user explicitly requests verbose output (--verbose),
       "__probe_ip" is intercepted and properly formatted as a hexadecimal
       kernel address, restoring its utility for debugging inline
       function hits.

Subject: [PATCH 3752/5214] nfs: don't skip revalidate on directory delegation
 when attrs flagged stale

On a local directory mutation (rename/create/unlink) the client marks
CHANGE / MTIME / CTIME as invalid in NFS_I(dir)->cache_validity.  When
a subsequent stat(2) enters __nfs_revalidate_inode() and finds a
directory delegation held, the function currently early-exits and
returns the cached (now stale) mtime to userspace without sending a
GETATTR RPC.

Keep the early-exit for the fast path, but take the RPC when CHANGE,
MTIME, or CTIME are already marked invalid.  The delegation alone is
not a guarantee of cached-attr freshness once the code itself has
flagged the cache as stale.

Subject: [PATCH 3753/5214] NFSv4/pNFS: reject zero-length r_addr in
 nfs4_decode_mp_ds_addr

nfs4_decode_mp_ds_addr() decodes the r_netid and r_addr opaques of a
netaddr4 from a GETDEVICEINFO multipath-DS body, then immediately
calls strrchr(buf, '.') to locate the port separator. Both decodes
use xdr_stream_decode_string_dup(), and the current code checks only
"nlen < 0" / "rlen < 0" before dereferencing the returned string.

When the on-wire opaque has length zero, xdr_stream_decode_opaque_inline()
returns 0 and xdr_stream_decode_string_dup() falls through to its
"*str = NULL; return ret" tail, leaving buf NULL with a return value
of 0. The "< 0" check does not catch this, and the next line is
strrchr(NULL, '.'), a kernel NULL pointer dereference reachable from
any pNFS-flexfile client mounted against a malicious or compromised
metadata server.

Reject the zero-length cases explicitly so the decoder fails with
-EBADMSG (treated as a malformed GETDEVICEINFO body) instead of
panicking the client.

Subject: [PATCH 3756/5214] KVM: x86: Fix shadow paging use-after-free due to
 unexpected role

Commit 0cb2af2ea66ad ("KVM: x86: Fix shadow paging use-after-free due
to unexpected GFN") fixed a shadow paging mismatch between stored and
computed GFNs; the bug could be triggered by changing a PDE mapping from
outside the guest, and then deleting a memslot.  The rmap_remove()
call would miss entries created after the PDE change because the GFN
of the leaf SPTE does not match the GFN of the struct kvm_mmu_page.

A similar hole however remains if the modified PDE points to a non-leaf
page.  In this case the gfn can be made to match, but the role does not
match: the original large 2MB page creates a kvm_mmu_page with direct=1,
while the new 4KB needs a kvm_mmu_page with direct=0.  However,
kvm_mmu_get_child_sp() does not compare the role, and therefore reuses
the page.

The next step is installing a leaf (4KB) SPTE on the new path which
records an rmap entry under the gfn resolved by the walk.  But when
that child is zapped its parent kvm_mmu_page has direct=1 and
kvm_mmu_page_get_gfn() computes the gfn for the 4KB page as
sp->gfn + index instead of using sp->shadowed_translation[] (or sp->gfns[]
in older kernels).  It therefore fails to remove the recorded entry.

When the memslot is dropped the shadow page is freed but the rmap
entry survives, as in the scenario that was already fixed.  Code that
later walks that gfn (dirty logging, MMU notifier invalidation, and
so on) dereferences an sptep that lies in the freed page, causing the
use-after-free.

Subject: [PATCH 3757/5214] KVM: x86/mmu: Ensure hugepage is in by slot before
 checking max mapping level

When recovering hugepages in the shadow MMU, verify that the base gfn of
the shadow page is actually contained within the target memslot, *before*
querying the max mapping level given the shadow page's gfn.  Failure to
pre-check the validity of the gfn can lead to an out-of-bounds access to
the slot's lpage_info (which typically manifests as a host #PF because the
lpage_info is vmalloc'd) if the guest creates a hugepage mapping (in its
PTEs) that extends "below" the bounds of a memslot.

When faulting in memory for a guest, and the size of the guest mapping is
greater than KVM's (current) max mapping, then KVM will create a "direct"
shadow page (direct in that there are no gPTEs to shadow, and so the target
gfn is a direct calculation given the base gfn of the shadow page).  The
hugepage recovery flow looks for such direct shadow pages, as forcing 4KiB
mappings when dirty logging generates the guest > host mapping size case.
When the 4KiB restriction is lifted, then KVM can replace the shadow page
with a hugepage.

But if KVM originally used a smaller mapping than the guest because the
range of memory covered by the guest hugepage exceeds the bounds of a
memslot, then KVM will link a direct shadow page with a gfn that is outside
the bounds of the memslot being used to fault in memory.  The rmap entry
added for the leaf mapping is correct and within bounds, but the gfn of the
leaf SPTE's parent shadow page will be out of bounds.

Don't bother pre-checking the bounds of the potential hugepage, i.e. don't
check that e.g. sp->gfn + KVM_PAGES_PER_HPAGE(sp->role.level + 1) is also
within the memslot, as the checks performed by kvm_mmu_max_mapping_level()
are a superset of the basic bounds checks.  I.e. pre-checking the full
range would be a dubious micro-optimization.

Subject: [PATCH 3760/5214] perf symbols: Fix bswap copy-paste error for 32-bit
 ELF p_filesz

filename__read_build_id() byte-swaps 32-bit ELF program headers on
cross-endian files, but line 178 passes p_offset to bswap_32() instead
of p_filesz:

  hdrs.phdr32[i].p_filesz = bswap_32(hdrs.phdr32[i].p_offset);

This clobbers p_filesz with the already-swapped p_offset value.  The
64-bit path on line 182 is correct and swaps p_filesz from p_filesz.

The consequence is that the PT_NOTE segment read uses the wrong size,
which can cause either a short read (missing the build-id) or an
oversized read (reading past the segment into adjacent data).

Fix by swapping the correct field.

Subject: [PATCH 3761/5214] perf symbols: Validate p_filesz before use in
 filename__read_build_id()

filename__read_build_id() stores ELF p_filesz in a ssize_t variable.
A crafted 32-bit ELF with p_filesz = 0xFFFFFFFF produces ssize_t value
-1.  The comparison `p_filesz > buf_size` evaluates false because signed
-1 is less than any non-negative buf_size, so the realloc is skipped and
buf remains NULL.

The subsequent read(fd, NULL, -1) returns -1, which equals p_filesz,
passing the error check.  read_build_id() then dereferences the NULL
buffer.

Add an explicit check for p_filesz <= 0 before using the value,
catching both zero-length and sign-wrapped negative sizes from crafted
ELF files.

 notes in sysfs__read_build_id()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sysfs__read_build_id() iterates ELF note headers from sysfs files in a
while(1) loop.  If the file contains a zero-filled note header (both
n_namesz and n_descsz are 0), the code computes n = namesz + descsz = 0
and calls read(fd, bf, 0).  read() with count 0 returns 0, which
matches the expected (ssize_t)n value, so the error check passes and
the loop repeats — reading the same zero bytes and spinning forever.

This can happen with corrupted or zero-padded sysfs pseudo-files.

Add a check for n == 0 before the read, since no valid ELF note has
both name and description of zero length.

Subject: [PATCH 3763/5214] perf dso: Fix heap overflow in dso__get_filename()
 on decompressed path

dso__get_filename() allocates name with malloc(PATH_MAX), but the
dso__filename_with_chroot() path replaces name with an asprintf'd
exact-size string (e.g. 8 bytes for "/a/b.ko").  When the DSO needs
decompression, dso__decompress_kmodule_path() writes the temp path
("/tmp/perf-kmod-XXXXXX", 22 bytes) into newpath, and strcpy(name,
newpath) overflows the smaller allocation.

Replace the strcpy with strdup(newpath) + free(name) so the buffer
is always correctly sized for its content.

Subject: [PATCH 3764/5214] perf dso: Set error code when open() fails on
 uncompressed fallback path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

filename__decompress() has an early return for files that are not
actually compressed, where it calls open() directly.  When open()
fails, the function returns -1 but never sets *err.  The caller chain
(decompress_kmodule → dso__decompress_kmodule_path → dso__get_filename)
then reads *dso__load_errno(dso) to set errno, but that field was never
populated, so errno gets a stale or zero value.

With errno=0, __open_dso() computes fd = -errno = 0, which is non-
negative, so callers treat fd 0 (stdin) as a valid DSO file descriptor.

Set *err = errno when open() fails on the uncompressed path, matching
the error handling on the compressed path at line 354.

 construction

get_kernel_version() in machine.c and dso__load_guest_kernel_sym() in
symbol.c use sprintf() to construct paths by prepending root_dir to
"/proc/version" and "/proc/kallsyms" respectively.  Both write into
PATH_MAX stack buffers, but root_dir comes from --guestmount or KVM
configuration and is not length-checked.  A root_dir at or near
PATH_MAX causes a stack buffer overflow.

Switch to snprintf() with sizeof(path) to prevent overflow.

Subject: [PATCH 3766/5214] perf hwmon: Fix fd check to accept fd 0 in
 hwmon_pmu__describe_items()

hwmon_pmu__describe_items() checks 'if (fd > 0)' after openat(), which
incorrectly rejects fd 0.  While fd 0 is normally stdin, if stdin has
been closed (common in daemon/service contexts), the kernel reuses fd 0
for the next open.  With fd > 0, the sysfs file is not read and the fd

Change to 'if (fd >= 0)' to match the standard openat() error check.

Subject: [PATCH 3767/5214] perf sched: Replace (void*)1 sentinel with proper
 runtime allocation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

map__findnew_thread() marks color-pid threads by storing (void*)1 as
the thread private data via thread__set_priv().  This sentinel value
causes two problems:

1. thread__get_runtime() returns (void*)1 as a struct thread_runtime
   pointer.  Any field access (e.g. tr->shortname) dereferences address
   1, which is an unmapped page — immediate segfault.

2. cmd_sched() registers free() as the thread priv destructor, so thread
   cleanup calls free((void*)1) — undefined behavior that corrupts the
   heap on many allocators.

Fix by adding a 'color' flag to struct thread_runtime and allocating a
real runtime struct for color-pid threads.  thread__has_color() now
checks the flag instead of relying on priv being non-NULL.

Subject: [PATCH 3768/5214] perf bpf: Validate func_info_rec_size and sub_id in
 synthesize_bpf_prog_name()

synthesize_bpf_prog_name() computes a pointer into the func_info array
using sub_id * info->func_info_rec_size without validating either value.
Both come from perf.data and are untrusted:

- A func_info_rec_size smaller than sizeof(struct bpf_func_info) means
  the finfo pointer would reference a truncated entry, reading past it
  into adjacent data.

- A sub_id >= nr_func_info computes an offset past the func_info buffer,
  causing an out-of-bounds read.

Add bounds checks for both values before computing the pointer offset.
When validation fails, fall through to the non-BTF name path instead
of reading garbage.

Subject: [PATCH 3769/5214] perf bpf: Reject oversized BPF metadata events that
 truncate header.size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

bpf_metadata_alloc() computes event_size from the number of BPF metadata
variables and stores it in header.size, which is __u16.  With 204 or
more .rodata variables prefixed "bpf_metadata_", event_size exceeds
65535 and silently truncates.

The truncated header.size causes synthesize_perf_record_bpf_metadata()
to allocate a buffer sized by the truncated value, then memcpy the full
event data into it — a heap buffer overflow.

Add a check that event_size fits in __u16 before proceeding.  BPF
programs with that many metadata variables are exotic enough that
silently dropping the metadata is acceptable.

Subject: [PATCH 3770/5214] perf bpf: Bounds-check array offsets in
 bpil_offs_to_addr()

bpil_offs_to_addr() converts offsets stored in perf.data's
bpf_prog_info_linear structure into heap pointers by adding the offset
to the data allocation base.  The offsets come from untrusted file input
and are not validated against data_len.

If an offset exceeds data_len, the computed address points outside the
allocated data buffer.  Callers like synthesize_bpf_prog_name() then
dereference prog_tags[sub_id] or func_info pointers, reading arbitrary
heap memory.

Add a bounds check: when an offset exceeds data_len, zero the field
and skip the conversion.  This prevents out-of-bounds pointer
construction from crafted perf.data files.

 signed comparison

metadata[j][CS_ETM_CPU] is a u64 from perf.data, but the comparison
with max_cpu casts it to (int).  A crafted value like 0xFFFFFFFF becomes
-1 after the cast, which compares less than max_cpu (0), so the queue
array is never sized to accommodate it.  When the value is later passed
to cs_etm__get_queue(), it indexes queue_array with the original large
value, causing an out-of-bounds access.

Validate that CS_ETM_CPU fits in an int before using it in the signed
comparison.

Subject: [PATCH 3774/5214] perf evsel: Add lazy-initialized probe type
 detection helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Several places in perf need to check whether an evsel is a kprobe or
uprobe, which requires looking up the PMU by name via evsel__find_pmu().
This lookup walks the PMU list each time, which is wasteful when the
same evsel is checked repeatedly.

Add evsel__is_kprobe(), evsel__is_uprobe(), and evsel__is_probe() that
resolve the probe type on first call via evsel__pmu_name() and cache
the result in a 3-bit field (probe_type) in struct evsel.  The field
fits in existing padding after the bool fields, so struct size does not
grow.

The enum uses PROBE__UNKNOWN (0) as the uninitialized sentinel —
explicitly set in evsel__init() — so the lookup happens on first use.
PROBE__NOPE (1) caches "not a probe" to avoid repeated negative lookups.

PMU-based probes (kprobe/uprobe PMU) are detected by PMU name.
Ftrace-based dynamic probes (created via tracefs, reported as PMU
"tracepoint") are detected by the __probe_ip field that the kernel
adds to all dynamic probe formats.  This covers kprobes, uprobes, and
fprobes regardless of their group/system name.

Subject: [PATCH 3775/5214] perf trace: Guard __probe_ip suppression with
 evsel__is_probe()

trace__fprintf_tp_fields() compares every field name against
"__probe_ip" for all tracepoint events, but this field is only
implicitly added by the Ftrace subsystem to bare dynamic probes.

Add an evsel__is_probe() check before the strcmp so the string
comparison is skipped entirely for non-probe events.

Subject: [PATCH 3776/5214] Input: mms114 - reject an oversized device packet
 size

mms114_interrupt() reads a packet of touch data from the device into a
fixed-size on-stack buffer

	struct mms114_touch touch[MMS114_MAX_TOUCH];

which holds MMS114_MAX_TOUCH (10) events of MMS114_EVENT_SIZE (8) bytes,
i.e. 80 bytes. The length of the I2C read into it is taken verbatim from
the device:

	packet_size = mms114_read_reg(data, MMS114_PACKET_SIZE);
	if (packet_size <= 0)
		goto out;
	...
	error = __mms114_read_reg(data, MMS114_INFORMATION, packet_size,
			(u8 *)touch);

packet_size is a single device register byte (0x0F) and the only check
is the lower bound packet_size <= 0; it is never bounded against the
size of touch[]. A malfunctioning, malicious or counterfeit controller
(or an attacker tampering with the I2C bus) can report a packet_size of
up to 255, so __mms114_read_reg() writes up to 175 bytes past the end of
touch[] on the IRQ-thread stack: a stack out-of-bounds write that can
overwrite the stack canary, saved registers and the return address.

A well-formed device never reports more than the buffer holds, so reject
an oversized packet and drop the report, consistent with the handler's
other error paths, rather than reading past the buffer.

During a syscall restart, block KUAP so that pending interrupts can be
replayed. The original KUAP state is not restored before returning to
userspace, causing subsequent userspace accesses to fault and eventually
trigger bad_access_pkey(), crashing the kernel.

The original KUAP register values are already saved in
arch_enter_from_user_mode(). Restore them on the syscall restart exit
path before returning to userspace.

Subject: [PATCH 3780/5214] powerpc/fadump: define MIN_RMA in bytes rather than
 MB

The MIN_RMA size checks in fadump_setup_param_area() use
(MIN_RMA * 1024 * 1024), which is evaluated in int and can
overflow when MIN_RMA is increased to values such as SZ_2G,
triggering compiler warnings such as:

warning: integer overflow in expression of type 'int'
results in '0' [-Woverflow]

Define MIN_RMA directly in bytes using SZ_1M and update the
callers accordingly. This avoids repeated unit conversions and
prevents integer overflow.

Also convert MIN_RMA back to MB when populating the firmware
architecture vector, since firmware expects the value in MB.

Subject: [PATCH 3781/5214] io_uring/nop: fix file reference leak with
 IOSQE_FIXED_FILE

NOP file-acquisition support choses between a fixed (registered) file and
a normal fget()'d file based on its own IORING_NOP_FIXED_FILE flag in
sqe->nop_flags. However, a request's REQ_F_FIXED_FILE is set
independently from the generic IOSQE_FIXED_FILE sqe flag during request
init, before the issue handler runs.

If a NOP is submitted with IOSQE_FIXED_FILE set (so REQ_F_FIXED_FILE is
set) but without IORING_NOP_FIXED_FILE, io_nop() takes the normal path
and grabs a real reference via io_file_get_normal(). On completion,
io_put_file() only drops the reference when REQ_F_FIXED_FILE is clear,
so the fget()'d file is never released and leaks:

  BUG: memory leak
  unreferenced object 0xffff88800f42c240 (size 176):
    kmem_cache_alloc_noprof+0x358/0x440
    alloc_empty_file+0x57/0x180
    path_openat+0x44/0x1e50
    do_file_open+0x121/0x200
    do_sys_openat2+0xa7/0x150
    __x64_sys_openat+0x82/0xf0

Decide between fixed and normal file acquisition from REQ_F_FIXED_FILE,
the same way io_assign_file() does for every other opcode, and fold
IORING_NOP_FIXED_FILE into REQ_F_FIXED_FILE at prep time.

Subject: [PATCH 3784/5214] i2c: qcom-cci: Move cci_init() under cci_reset()
 function

On probe or runtime errors cci_reset() is called and it should be coupled
with cci_init(), instead of doing this on caller's side, embed cci_init()
directly into the cci_reset() function.

This is a non-functional change, cci_reset() and cci_init() function
bodies are reordered.

Subject: [PATCH 3785/5214] i2c: qcom-cci: Remove overcautious disable_irq()
 calls

In cci_probe() the controller's interrupt is requested using a devres
managed API, and in cci_probe() error path and cci_remove() it'd be
safe to rely on devres mechanism to free and shutdown the interrupt,
thus explicit disable_irq() calls can be removed as unnecessary ones.

Subject: [PATCH 3786/5214] i2c: davinci: Unregister cpufreq notifier on probe
 failure

davinci_i2c_probe() registers a cpufreq transition notifier before adding
the I2C adapter.  If i2c_add_numbered_adapter() fails, the probe error path
releases the device resources without unregistering the notifier.

Add a dedicated error path to unregister the cpufreq notifier after
i2c_add_numbered_adapter() fails.

-This binding describes an I2C bus multiplexer that uses a single register

-- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side
-  port is connected to.
-* Standard I2C mux properties. See i2c-mux.yaml in this directory.

-  The <offset size> depends on its parent node. It can be any memory-mapped
-  address. The size must be either 1, 2, or 4 bytes. If reg is omitted, the
-  resource of this device will be used.
-- little-endian: The existence indicates the register is in little endian.
-- big-endian: The existence indicates the register is in big endian.
-  If both little-endian and big-endian are omitted, the endianness of the
-  CPU will be used.
-- write-only: The existence indicates the register is write-only.
-- idle-state: value to set the muxer to when idle. When no value is
-  given, it defaults to the last value used.
-
-Whenever an access is made to a device on a child bus, the value set

 finalizing cache after error

During regcache initialization, if an error occurs in the
cache_ops->populate callback, and if cache operations include an exit
callback, the error code from populate() is overwritten with the return
value from exit(). This hides the error condition from the caller of
regcache_init(), and can cause NULL pointer dereferences when the regcache
is later accessed.

Finalize commit c33c794828f2 ("mm: ptep_get() conversion") and
replace direct page table entry dereferencing with the proper
accessors (ptep_get(), pmdp_get(), etc.).

Override the default getter implementations even though they are
currently identical: pud_clear(), p4d_clear(), and pgd_clear()
require corresponding architecture-specific getters, but these
are not yet defined. This avoids a dependency loop.

Subject: [PATCH 3791/5214] io_uring: get rid of tw_pending for !DEFER task
 work

The normal task_work path used a tw_pending bit to ensure the callback
was only added once: the mpscq drains incrementally, so a single
tctx_task_work() run can take the queue through empty -> non-empty
several times, and each transition would otherwise re-add the already
pending callback_head. This corrupts the task_work list, and is what
tw_pending protects again.

This can go away, if we stop running the task_work as soon as the queue
empties.

Subject: [PATCH 3793/5214] block: fix IORING_URING_CMD_REISSUE flags check in
 blkdev_uring_cmd

blkdev_uring_cmd() checks IORING_URING_CMD_REISSUE to determine whether
this is the first issue. However, this flag lives in cmd->flags instead
of issue_flags.

Coincidentally, IO_URING_F_NONBLOCK shares bit 31 with
IORING_URING_CMD_REISSUE. As a result, the SQE read was never performed,
bic->len remained zero, and every BLOCK_URING_CMD_DISCARD failed with
-EINVAL.

Fix it by checking cmd->flags as intended.

Subject: [PATCH 3794/5214] block: Remove redundant plug in __submit_bio()

The patch removes the automatic plug/unplug operations from __submit_bio()
that were added to cache nsecs time when no explicit plug is used.

The plug mechanism is most effective when batching multiple I/O
operations together. Creating a plug for every bio submission
provides minimal benefit while adding function call overhead and
stack usage for every I/O operation.

Below is performance comparison with the latest upstream kernel.

Subject: [PATCH 3795/5214] io_uring/register: preserve SQ array entries on
 resize

Ring resizing copies pending SQEs from the old SQE array into the new
one so submissions queued before the resize can still be consumed
afterwards.

That copy currently walks the SQ head/tail range directly. This is only
correct when there is no SQ array indirection. With a regular SQ array,
each pending SQ entry contains an index into the SQE array. After resize,
ctx->sq_array is repointed at the newly allocated array, so pending
entries lose their old logical-to-physical mapping and may submit the
wrong SQE.

Remember the old and new SQ arrays while migrating pending SQ entries. For
each pending entry, copy the SQE selected by the old array into the new
destination slot and rebuild the new array entry to point at the copied
SQE. Keep invalid user-provided entries invalid so the normal submission
path still drops them after resize.

Subject: [PATCH 3796/5214] kernel/fork: clear PF_BLOCK_TS in copy_process()

PF_BLOCK_TS is only set in blk_time_get_ns() when current->plug is
non-NULL, and blk_finish_plug() clears it via __blk_flush_plug()
before NULLing the plug pointer.  copy_process() breaks the
invariant by inheriting PF_BLOCK_TS from the parent while resetting
the child's plug to NULL.

Clear PF_BLOCK_TS alongside that assignment so callers can rely on
"PF_BLOCK_TS set implies current->plug != NULL" and dereference
current->plug unguarded.

Subject: [PATCH 3797/5214] block: invalidate cached plug timestamp after task
 switch

blk_time_get_ns() caches ktime_get_ns() in current->plug->cur_ktime
and marks the task with PF_BLOCK_TS. That cache is only valid while the
task keeps running; if the task is switched out, wall-clock time
advances and the cached value must not be reused when the task runs again.

The existing invalidation covers explicit plug flushes through
__blk_flush_plug(), and the schedule() / rtmutex paths through
sched_update_worker(). It does not cover in-kernel preemption paths such
as preempt_schedule(), preempt_schedule_notrace(), and
preempt_schedule_irq(), which enter __schedule(SM_PREEMPT) directly and
return without calling sched_update_worker().

As a result, a task preempted while holding a plug with PF_BLOCK_TS set
can reuse a stale plug->cur_ktime after it is scheduled back in. blk-iocost
then consumes that stale timestamp through ioc_now(), producing stale vnow
values for throttle decisions, and through ioc_rqos_done(), inflating
on-queue time and feeding false missed-QoS samples into vrate
adjustment.

Move the schedule-side invalidation to finish_task_switch(), which runs
for the scheduled-in task after every actual context switch regardless
of which schedule entry point was used. Keep __blk_flush_plug() as the
explicit flush/finish-plug invalidation path, and remove only the
PF_BLOCK_TS handling from sched_update_worker().

Subject: [PATCH 3798/5214] drm/i915/mst: Call intel_pfit_compute_config() for
 sharpness filter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sharpness filter property is on the CRTC (as opposed to the
connector) so the expectation is that it's usable on all output
types. Since the sharpness filter is now fully integrateds into
the normal pfit code intel_pfit_compute_config() must be called
from the encoder .compute_config() on all relevant output types.

Sharpness filter is supported on LNL+ so only HDMI and DP SST/MST
outputs are actually relevant. I already took care of HDMI and
DP SST, but (as usual) forgot about DP MST. Add the missing
intel_pfit_compute_config() call to make the sharpness filter
operational on DP MST as well.

Subject: [PATCH 3799/5214] drm/i915: clear CRTC color blob pointers after
 dropping refs

intel_crtc_put_color_blobs() drops the CRTC color blob references, but
leaves the corresponding pointers unchanged.

This can matter in intel_crtc_prepare_cleared_state(), which frees the
old CRTC hw state before calling intel_dp_tunnel_atomic_clear_stream_bw().
The latter can fail while looking up the DP tunnel group state, for
example with -EDEADLK.

If that happens, the function returns without completing the cleared
state preparation. The failed atomic state will then be cleared by the
atomic core and intel_crtc_free_hw_state() can be called again for the
same state, dropping the same blob references again.

Clear the blob pointers after dropping the references so repeated cleanup
of the same CRTC hw state is safe.

Subject: [PATCH 3800/5214] drm/i915/mtl+: Enable PPS before PLL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enabling PPS after a display port's PLL is enabled leads to PLL / DDI
BUF timeouts during system resuming after a long (> 45 mins) suspended
state, at least on some ARL and MTL laptops, either all or some of them
also containing an Nvidia GPU. Enabling PPS first and then the PLL fixes
the problem for all the reporters.

A similar issue is seen when enabling an external DP output on PHY B
(vs. PHY A in the above eDP cases), where this change will not have any
effect (since no PPS is used in that case). There isn't any direct
connection between PPS and PLL, so the fix for eDP works by some
side-effect only. However Bspec does seem to require enabling PPS first,
so let's do that. Further investigation continues on the actual root
cause and a cure for external panels.

Subject: [PATCH 3802/5214] Revert "drm/xe: Skip exec queue schedule toggle if
 queue is idle during suspend"

This reverts commit 8533051ce92015e9cc6f75e0d52119b9d91610b6.

The idle-skip optimization bypasses GuC suspend, so the GPU may not
perform the context switch that flushes TLB entries for invalidated
userptr VMAs. In LR/preempt-fence VM mode, this can lead to missed TLB
invalidation and page faults during userptr invalidation tests.

Restore unconditional schedule toggling on suspend so the context-switch
TLB flush is always performed.

This optimization will be reintroduced with a fix that does not skip
suspend in LR/preempt-fence VM mode.

Subject: [PATCH 3803/5214] drm/xe: Clear pending_disable before signaling
 suspend fence

In the schedule-disable done path for suspend, we
signal the suspend fence before clearing pending_disable.

That wakeup can let suspend_wait complete and resume be queued
immediately. The resume path may then reach enable_scheduling()
while pending_disable is still set and hit the
!exec_queue_pending_disable(q) assertion.

Fix this by clearing pending_disable before signaling
the suspend fence, so any resumed transition observes a
consistent state.

Subject: [PATCH 3808/5214] drm/xe: include all registered queues in TLB
 invalidation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Context-based TLB invalidation currently selects only scheduling-active
exec queues via q->ops->active(). During rebind flows, queues may be
suspended (or transitioning through resume) while still owning valid
translations, causing them to be skipped from invalidation and leading
to missed TLB invalidations on LR rebinds.

The underlying issue is a TOCTOU: q->guc->state bits are flipped lock-free
from enable_scheduling(), disable_scheduling{,_deregister}(), the
suspend/resume sched-msg handlers, handle_sched_done(), and
guc_exec_queue_stop(); nothing in send_tlb_inval_ctx_ppgtt() serializes
against them, so any state-based predicate can race.

Include all the registered queues so that TLB invalidations are not
missed. This is race-free because list membership on vm->exec_queues.list
is stable under vm->exec_queues.lock held by the caller. The performance
impact is expected to be minimal and harmless. If it does turn out to be
a concern, we can come back with a race-safe solution to ignore certain
queues.

dma_fence_get() and stores it in rfence->fence.  It then calls
dma_fence_add_callback() and handles two cases: when the callback
is successfully registered (err == 0) the fence is transferred to
the tree for later cleanup; when the fence is already signaled
(err == -ENOENT) it manually drops the extra reference with
dma_fence_put(fence).

However, dma_fence_add_callback() can fail with other errors
(e.g. -EINVAL) and in that case the code falls through to the free:
label without releasing the acquired reference, leaking it.

Fix the leak by adding an else branch that calls dma_fence_put()
before jumping to free: for any error other than -ENOENT.

Subject: [PATCH 3810/5214] drm/xe: fix job timeout recovery for unstarted jobs
 and kernel queues

A job that GuC never scheduled (never started) indicates a GuC
scheduling failure; previously such jobs were silently errored out
instead of triggering a GT reset to recover. Trigger a GT reset and
resubmit them, but only when the queue was not already killed or banned:
an unstarted job on an already banned queue is the ban working as
intended and must neither clear the ban nor kick off a reset, otherwise
a banned userspace queue could be resurrected and spam GT resets.

Kernel queues are always recovered this way and wedge the device once
recovery attempts are exhausted, since kernel work must not silently
fail. A started job that times out on a userspace VM bind queue stays
banned rather than being reset and retried.

The queue is banned early in the timeout handler to signal the G2H
scheduling-done handler so it wakes the disable-scheduling waiter;
without it the waiter sleeps the full 5s timeout. When a reset is
warranted the ban is cleared before rearming so that
guc_exec_queue_start() can resubmit jobs after the GT reset - a
still-banned queue would block resubmission and cause an infinite TDR
loop. The already-banned case is gated out before this point via
skip_timeout_check, so it is unaffected.

v2: (Himal) Do it for any queue type, not just kernel/migration
v3: - (Sashiko and Sanjay): don't clear the ban / GT reset for already
      killed/banned queues on unstarted-job timeout
    - Update commit message
    - (Matt) Add Fixes tag

Subject: [PATCH 3811/5214] drm/xe: Fix wa_oob codegen recipe for external
 module builds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When building with 'make M=drivers/gpu/drm/xe modules', kbuild invokes
scripts/Makefile.build with obj=., causing $(obj) to expand to '.'.
Make normalizes './xe_gen_wa_oob' to 'xe_gen_wa_oob' when constructing
the $^ automatic variable (target name normalization), so the recipe
command becomes just 'xe_gen_wa_oob ...' without any path prefix, and
the shell cannot find the tool.

Fix by replacing $^ with explicit $(obj)/xe_gen_wa_oob and
$(src)/<rules-file> references in both wa_oob recipe commands.
In recipe strings, make does not apply target name normalization, so
$(obj)/xe_gen_wa_oob correctly expands to './xe_gen_wa_oob' and the
shell can execute it. This matches the pattern already used by other
DRM drivers (e.g. radeon's mkregtable).

Subject: [PATCH 3812/5214] drm/xe: Set TTM device beneficial_order to 9 (2M)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Set the TTM device beneficial_order to 9 (2M), which is the sweet
spot for Xe when attempting reclaim on system memory BOs, as it matches
the large GPU page size. This ensures reclaim is attempted at the most
effective order for the driver.

This fixes an issue where an order-10 (4M) allocation cannot be found
despite an abundance of memory. The 4M allocation triggers reclaim,
unnecessarily evicting the working set and hurting performance. Since
the TTM infrastructure was introduced recently, we are tagging the TTM
patch as the Fixes target, even though this resolves an Xe-side problem.

Subject: [PATCH 3813/5214] drm/xe/guc: Fix buffer overflow in steered register
 list allocation

The size calculation for the steered register extarray uses only the
geometry DSS mask (g_dss_mask) to determine the number of entries to
allocate:

  total = bitmap_weight(gt->fuse_topo.g_dss_mask, ...) * steer_reg_num;

However, the filling loop uses for_each_dss_steering(), which iterates
over for_each_dss(), defined as the union of g_dss_mask and c_dss_mask
(geometry + compute DSS). On platforms with compute-only DSS bits, the
loop writes past the allocated buffer, corrupting adjacent slab objects.

This manifests as list_del corruption and SLUB redzone overwrites during
drm_managed_release on device unbind, since the overflow corrupts the
drmres list_head of neighboring allocations.

Fix by computing the allocation size using the union of both DSS masks,
matching the iteration pattern of for_each_dss_steering().

Subject: [PATCH 3814/5214] drm/xe: Add compact-PT and addr mask handling for
 page reclaim

Current implementation of generate_reclaim_entry() overlooks some
differences between the different page implementations: address masking
and compact 64K page handling.

Address masking of each leaf varies depending on the leaf entry size.
generate_reclaim_entry() is using XE_PTE_ADDR_MASK [51:12] for all leaf
entries. For 2MB PTEs, bit 12 (PAT) is part of the flags so the old mask
corrupts the physical address extraction.

64K pages can be represented as PS64 and a compact PT, which the latter
was not handled. Compact pages aren't walked by the unbind walker, so we
separately walk through the compact PT to ensure none of the leaf 64K
PTEs are dropped. Previously, compact PT were causing an abort since it
was considered covered and not descended into.

v2:
 - Update 64K entry/unbind walker for 64K compact PT handling. (Matthew)
 - Rework calculations of reclamation and address mask size.
 - Add new func abstracting the error handling before generating the
   reclaim entry.

v3:
 - Report finer addr granularity in abort debug print for compact.
   (Zongyao)
 - Add comments for ADDR_MASK usage. (Zongyao)
 - Drop existing phys_addr asserts, the new XE_PAGE_ADDR_MASK clears
   bits checked, so redundant asserts. (Sashiko)
 - WARN_ON to verify compact pt and edge pt won't be possible.

Subject: [PATCH 3816/5214] accel/amdxdna: Use caller client for debug BO sync

amdxdna_drm_sync_bo_ioctl() looks up args->handle in the ioctl caller's
drm_file. For SYNC_DIRECT_FROM_DEVICE, it then calls
amdxdna_hwctx_sync_debug_bo(), but passes abo->client.

amdxdna_hwctx_sync_debug_bo() uses the passed client both as the handle
namespace for debug_bo_hdl and as the owner of the hardware context xarray.
Those must match the file that supplied args->handle. The BO's stored
client pointer is object state, not the ioctl context.

Pass filp->driver_priv instead, matching the original handle lookup.

Subject: [PATCH 3818/5214] spi: uniphier: Fix completion initialization order
 before devm_request_irq()

The driver calls devm_request_irq() before initializing the completion
used by the interrupt handler. Because the interrupt may occur immediately
after devm_request_irq(), the handler may execute before init_completion().

This may result in calling complete() on an uninitialized completion,
causing undefined behavior. This has been observed with KASAN.

Fix this by initializing the completion before registering the IRQ.

Subject: [PATCH 3819/5214] spi: dw: fix wrong BAUDR setting after resume

After resuming from suspend to ram, spi transfer stops working. Further
debugging shows that the BAUDR register isn't correctly set, this is
due to dws->current_freq doesn't match the HW BAUDR setting,
specifically, the dws->current_freq equals to speed_hz, but BAUDR is 0.
so the dw_spi_set_clk() in below code won't be called:

        if (dws->current_freq != speed_hz) {
                dw_spi_set_clk(dws, clk_div);
                dws->current_freq = speed_hz;
        }

The mismatch comes from dw_spi_shutdown_chip() when suspending.
Fix this mismatch by setting dws->current_freq to 0 as well when
clearing BAUDR reg in dw_spi_shutdown_chip().

Subject: [PATCH 3820/5214] block: revert the iov_iter after a short copy in
 bio_iov_iter_bounce_write()

For the incoming IOMAP_DIO_BOUNCE flag usage inside btrfs, it's pretty
easy to hit short copy inside bio_iov_iter_bounce_write().

This is because btrfs has disabled page fault to avoid certain deadlock
during direct writes, and instead btrfs manually fault in the pages then
retry.

And inside bio_iov_iter_bounce_write(), if we hit a short write, we
didn't revert the iov_iter, which can cause problems like unexpected
garbage for the next retry.

Revert the iov_iter after a short copy.

One thing to note is that, the folio is allocated then immediately
queued into the bio, so the proper revert size should be
(bi_size - this_len + copied).

iov_iter::nofault to prevent deadlock when a page fault is needed to
read out the buffer.

However bio_iov_iter_bounce_write() doesn't respect iov_iter::nofault
flag, and just call a plain copy_from_iter() so it can still trigger
page fault and cause deadlock in btrfs.

Fix it by utilizing copy_folio_from_iter_atomic() if nofault flag is
set, otherwise use copy_folio_from_iter().

Protect master->dev_nack_retry_count against concurrent sysfs updates

Consequently, combine adjacent return statements into one.

For consistency, read dev_nack_retry_count while holding the bus normaluse

The assignment in this driver uses a mixed way to initialize the
platform_device_id array. .name is assigned by name and .driver_data by
position. Unify that to use named assignment for both struct members.
This is needed for a planned change to struct platform_device_id
replacing .driver_data by an anonymous union.

In order to easily use `IntoBytes`, add it to the prelude.

This adds both the trait (`zerocopy::IntoBytes`) as well as the derive
macro (`zerocopy_derive::IntoBytes`).

[ This patch will simplify using the feature in several trees next cycle.

  Gary writes:

    This is wanted because I want to convert the upcoming I/O projection
    series to use `zerocopy` traits rather than keep using transmute
    module.

    It is most helpful for derives in doc tests; I do not want to
    explicitly use `#[derive(zerocopy_derive::IntoBytes)]` in the
    doc tests.

Subject: [PATCH 3830/5214] i2c: ls2x-v2: return IRQ_HANDLED after servicing an
 error

The event ISR reads SR1 and, when an error flag (ARLO/AF/BERR) is set,
calls loongson2_i2c_isr_error() which clears the offending flag, issues
STOP for the AF case, records msg->result, masks every CR2 interrupt
enable and completes the waiter. The handler then returns IRQ_NONE,
declaring to the IRQ core that the device did not interrupt.

That report is wrong. The device did interrupt and the handler fully
serviced it. Because the IRQ is requested with IRQF_SHARED, the genirq
spurious-IRQ tracker counts each error as unhandled. A bus that emits
sporadic NACKs, arbitration losses or bus errors will therefore march
toward the spurious-IRQ threshold and the line can end up disabled,
wedging the controller.

Return IRQ_HANDLED on this path. The other IRQ_NONE site, taken when
neither an event nor an error bit is set, remains correct.

Various names for Qualcomm as a company are used in user-visible config
options: QCOM, Qualcomm and Qualcomm Technologies.  Switch to unified
"Qualcomm" so it will be easier for users to identify the options when
for example running menuconfig.

Subject: [PATCH 3832/5214] rust: bitfield: mark `Debug` impl as `#[inline]`

A `Debug` impl is for debugging and is normally not used, and therefore
should ideally not be code-generated unless used. However, Rust has no way
of knowing if a dependent crate is going to use the trait impl or not, so
unless it is marked as `#[inline]`, it will be code-generated in the
defining crate (as it is not generic).

Mark the impl generated by bitfield macro `#[inline]`, so they do not stay
in the binary unless used.

This reduces nova-core.o .text by 17% (from 151922 bytes to 125676 bytes).

Both CoreI2C and the hardened versions of it on mpfs and pic64gx have a
reset pin. For the former, usually this is wired to a common fabric
reset not managed by software and for the latter two the platform
firmware takes them out of reset on first-party boards (or those using
modified versions of the vendor firmware), but not all boards may take
this approach. Permit providing a reset in devicetree for Linux, or
other devicetree-consuming software, to use.

 Overview
 ========
 
-EROFS filesystem stands for Enhanced Read-Only File System.  It aims to form a
-generic read-only filesystem solution for various read-only use cases instead
-of just focusing on storage space saving without considering any side effects
-of runtime performance.
+EROFS (Enhanced Read-Only File System) is a modern, efficient, and secure
+read-only kernel filesystem designed for various use cases including immutable
+system images, container images, application sandbox images, and dataset
+distribution.
 
-It is designed to meet the needs of flexibility, feature extendability and user
-payload friendly, etc.  Apart from those, it is still kept as a simple
-random-access friendly high-performance filesystem to get rid of unneeded I/O
-amplification and memory-resident overhead compared to similar approaches.
+An immutable image filesystem can be regarded as an enhanced archive format
+which allows golden images to be built once and mounted everywhere -- images are
+bit-for-bit identical across all deployments and can be verified, audited, or
+shared without concerns about runtime modifications (in this model, all user
+writes should be redirected into another trusted filesystem, for example, via
+overlayfs for copy-on-write-style redirection, by design).
 
-It is implemented to be a better choice for the following scenarios:
+EROFS is a dedicated implementation of the image filesystem idea above, with a
+flexible, hierarchical on-disk design so that needed features can be enabled on
+demand. Filesystem data in the core format is strictly block-aligned in order
+to perform optimally on all kinds of storage media, including block devices and
+memory-backed devices. The on-disk format is easy to parse and purposely avoids
+the unnecessary metadata redundancy found in generic writable filesystems, which
+can suffer from extra inconsistency issues -- making it ideal for security
+auditing and untrusted remote access. In addition, designs such as inline data,
+inline/shared extended attributes, and optimized (de)compression provide better
+space efficiency while maintaining high performance.

+In short, EROFS aims to be a better fit for the following scenarios:
 
- - part of a fully trusted read-only solution, which means it needs to be
+ - As part of a secure immutable storage solution, where it needs to be
    immutable and bit-for-bit identical to the official golden image for
-   their releases due to security or other considerations and
+   each individual copy, in order to meet security, data sharing, and/or
+   other requirements;
 
- - hope to minimize extra storage space with guaranteed end-to-end performance
-   by using compact layout, transparent file compression and direct access,
-   especially for those embedded devices with limited memory and high-density
-   hosts with numerous containers.

+   by using compact (meta)data layout, optimized transparent data compression,

-Here are the main features of EROFS:
+Here is the list of highlights:
 
- - Little endian on-disk design;
+ - Little endian on-disk design with 48-bit block addressing, supporting up
+   to 1 EiB filesystem capacity with 4 KiB block size;
 
- - Block-based distribution and file-based distribution over fscache are
-   supported;
+ - Two compact inode metadata layouts for space and performance efficiency:
 
- - Support multiple devices to refer to external blobs, which can be used
-   for container images;

Subject: [PATCH 3838/5214] gpiolib: acpi: Add robust bounds-checking for GPIO
 pin resources

Ensure that GPIO pin resource arrays are safely bounded before accessing
indices. Add explicit bounds checking in acpi_request_own_gpiod(),
acpi_gpio_irq_is_wake(), and acpi_gpiochip_alloc_event() to prevent
out-of-bounds array reads if the ACPI namespace provides malformed or empty
pin tables.

This change addresses potential safety issues arising from
inconsistent or invalid ACPI pin tables. It does not alter functional
behavior in well-formed tables.

Subject: [PATCH 3839/5214] gpiolib: acpi: Prevent out-of-bounds pin access in
 OperationRegion handler

The ACPI GPIO OperationRegion handler receives pin offsets as a
64-bit address. Previously, this value could be assigned to a pin index
without validation, potentially causing out-of-bounds access if
the ACPI table provides an invalid offset.

This patch explicitly checks that the 64-bit address is less than
agpio->pin_table_length before using it, returning AE_BAD_PARAMETER
if the check fails. Additionally, it makes the length calculation
overflow-safe and ensures proper unsigned types for loop counters.

This corrects the commit message from v5 to accurately reflect the
underlying issue, removing references to truncation or wrap-around,
which do not occur in ACPICA.

Subject: [PATCH 3840/5214] i2c: stm32f7: truncate clock period instead of
 rounding it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

stm32f7_i2c_compute_timing() derives the I2C clock source period
(i2cclk) with DIV_ROUND_CLOSEST, which may round it up. When the
period is overestimated, all timings computed from it (SCLDEL,
SDADEL, SCLL, SCLH) come out shorter on the wire than calculated,
and the resulting bus rate can exceed the requested speed, violating
the I2C specification minimums for tLOW and tHIGH.

For example, with a 104.45 MHz clock source (e.g. PCLK1, the
reset-default I2C clock source on STM32MP1), i2cclk is rounded from
9.574 ns up to 10 ns. Requesting a 400 kHz fast mode bus with
72/27 ns rise/fall times and no analog/digital filters then produces
an actual bus rate of 415.6 kHz with tLOW = 1254 ns, violating both
the 400 kHz maximum rate and the 1300 ns tLOW minimum of the
specification.

Truncate the period instead, so that it can only be underestimated.
The error then falls on the safe side: the programmed timings come
out slightly longer than computed and the bus runs marginally below
the target rate (375.3 kHz in the example above) while meeting the
specification.

i2cbus is left rounded-to-closest: it is only used as the target of
the clk_error comparison and is never multiplied into the programmed
timings, so nearest rounding remains accurate there.

Subject: [PATCH 3841/5214] ALSA: compress: Fix task creation error unwind
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

snd_compr_task_new() allocates the driver task before validating the
returned DMA buffers and reserving file descriptors. When either of
those later steps fails, the core frees its task wrapper and DMA-buffer
references without calling the driver's task_free() callback. Any
driver resources allocated by task_create() are therefore leaked.

The dual-fd allocation path also jumps to cleanup without storing the
negative get_unused_fd_flags() result in retval. Since retval still
contains the successful task_create() return value, TASK_CREATE can
incorrectly report success although the task was discarded.

Preserve the fd allocation errors and call task_free() when failure
occurs after a successful task_create() callback.

Subject: [PATCH 3842/5214] ALSA: hda/conexant: Add pin config quirk for Lenovo
 IdeaPad Slim 5 16AKP10

The Lenovo IdeaPad Slim 5 16AKP10 (PCI SSID 17aa:38b6) uses the
Conexant SN6140 codec. The internal microphone is on pin 0x1a but
the BIOS configures it with pin default 0x95a60120, which includes
a jack detection bit that causes the kernel to treat it as an
unplugged external mic rather than a fixed internal mic.

Add a pin config quirk that overrides pin 0x1a to 0x95a60130,
setting the connectivity bits to indicate a fixed/always-connected
device. This allows the internal microphone to be correctly
identified and used.

Subject: [PATCH 3843/5214] ALSA: usb-audio: qcom: Free sideband sg_table
 objects

The Qualcomm USB audio offload driver obtains an endpoint transfer-ring
table by calling xhci_sideband_get_endpoint_buffer(). This getter passes
the endpoint ring to xhci_ring_to_sgtable(), which allocates the outer
struct sg_table with kzalloc_obj(*sgt). The event-ring path is
equivalent: xhci_sideband_get_event_buffer() also returns the result of
xhci_ring_to_sgtable().

Inside xhci_ring_to_sgtable(), sg_alloc_table_from_pages() separately
allocates the scatterlist storage referenced by sgt->sgl. The returned
object therefore has two allocation layers: the outer struct sg_table
and its internal scatterlist storage.

The Qualcomm caller only invokes sg_free_table(sgt). sg_free_table()
releases the scatterlist storage owned by the table, but it does not
free the separately allocated outer struct sg_table. The local sgt
pointer is then discarded, so every successful endpoint or event-ring
query leaks the outer object.

Call kfree(sgt) after sg_free_table(sgt) in both setup paths, after the
required page and DMA addresses have been copied out.

Subject: [PATCH 3846/5214] i2c: imx-lpi2c: mark I2C adapter when hardware is
 powered down

On some i.MX platforms, certain I2C client drivers keep a periodic
workqueue which continues to trigger I2C transfers.

During system suspend/resume, there exists a time window between:
  - suspend_noirq and the system entering suspend
  - the system starting to resume and resume_noirq

In this window, the I2C controller resources such as clock and pinctrl
may already be disabled or not yet restored.

If a workqueue triggers an I2C transfer in this period, the driver
attempts to access I2C registers while the hardware resources are
unavailable, which may lead to system hang.

Mark the I2C adapter as suspended during noirq suspend and block new
transfers until resume, ensuring that I2C transfers are only issued
when hardware resources are available.

Subject: [PATCH 3847/5214] xfrm: Fix xfrm state cache insertion race

The xfrm input state cache insertion code checks the validity of
the state before acquiring the global xfrm_state_lock.  Thus it's
possible for someone else to kill the state after it passed the
validity check, and then the insertion will add the dead state
to the cache.

Fix this by moving the validity check inside the lock.

This entire function is called on the input path, where BH must
be off (e.g., the caller of this function xfrm_input acquires
its spinlocks without disabling BH).

So there is no need to disable BH here or take the RCU read lock.
Remove both and replace them with an assertion that trips if BH
is accidentally enabled on some future calling path.

Subject: [PATCH 3849/5214] espintcp: use sk_msg_free_partial to fix partial
 send

sk_msg_free_partial() ensures consistency of the skmsg at every
iteration, without having to manually handle uncharges and offsets.
This simplifies the code, and fixes some bugs in skmsg accounting when
we don't send the full contents.

Subject: [PATCH 3850/5214] xfrm: validate selector family and prefixlen during
 match

syzbot reported a shift-out-of-bounds in xfrm_selector_match()
due to AF_UNSPEC selector with large prefixlen (e.g. 128) matched
against IPv4 flow (when XFRM_STATE_AF_UNSPEC is set).

Fix this by:

- Rejecting mismatched families in xfrm_selector_match.
- Returning false in addr4_match if prefixlen > 32.
- Returning false in addr_match if prefixlen > 128 (prevents overflow).

Fixes: 3f0ab59e6537 ("xfrm: validate new SA's prefixlen using SA family when sel.family is unset")

Subject: [PATCH 3852/5214] mfd: sec: Add support for S2MU005 PMIC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Samsung's S2MU005 PMIC includes subdevices for a charger, an MUIC (Micro
USB Interface Controller), and flash and RGB LED controllers.

S2MU005's interrupt registers divided into three domains, each for the
charger, flash LEDs, and the MUIC, packed into a single regmap IRQ chip
construct.

In devices other than S2MPG1X, the revision can be retrieved from the
first register of the PMIC regmap. In S2MU005 however, the location is
in offset 0x73. Introduce a switch-case block to allow selecting the
REG_ID register. S2MU005 also has a field mask for the revision. Apply
it using FIELD_GET() and get the extracted value.

Add initial support for S2MU005 in the PMIC driver, along with its three
interrupt chips, and support for allowing to fetch revision based on the
device variant.

Subject: [PATCH 3853/5214] mfd: sec: Set DMA coherent mask

Kernel logs are filled with "DMA mask not set" messages for every
sub-device. The device does not use DMA for communication, so these
messages are useless. Disable the coherent DMA mask for the PMIC device,
which is also propagated to sub-devices.

Subject: [PATCH 3856/5214] leds: pca9532: Don't stop blinking for non-zero
 brightness

pca9532 unexpectedly stopped blinking when changing brightness to a
non-zero value. To reproduce:

 echo timer > /sys/class/leds/led-1/trigger   # blinks
 echo 255 > /sys/class/leds/led-1/brightness  # blinking stops, light on
 cat /sys/class/leds/led-1/trigger            # still claims [timer]

According to Documentation/leds/leds-class.rst, only brightness = 0
shall be a stop condition:

> You can change the brightness value of a LED independently of the
> timer trigger. However, if you set the brightness value to LED_OFF it
> will also disable the timer trigger.

Therefore add a guard to continue blinking when brightness != LED_OFF,
similar to how pca955x does it since 575f10dc64a2 ("leds: pca955x: Add
HW blink support").

Subject: [PATCH 3858/5214] leds: trigger: gpio: Use
 GPIOD_FLAGS_BIT_NONEXCLUSIVE

When a GPIO is shared between the LED trigger driver and another driver,
the LED trigger driver needs to request the GPIO with
GPIOD_FLAGS_BIT_NONEXCLUSIVE to allow both drivers to monitor the same
GPIO pin.

Without this flag, if another driver has already claimed the GPIO,
the LED trigger driver's gpiod_get_optional() call fails silently,
and the LED trigger doesn't work.

This is needed for scenarios like:
- SFP module presence/status LED triggered by SFP Mod_ABS/Rx_LOS

Both GPIOs are also monitored by the SFP driver for module state
management, so they need to be shared.

Subject: [PATCH 3860/5214] docs: leds: Fix sysfs ABI reference in lp5812.rst

Documentation/ABI/testing/sysfs-class-led-multicolor is a plain ABI
description without a .rst suffix. The lp5812 documentation incorrectly
referred to sysfs-class-led-multicolor.rst, which does not exist.

This was reported by documentation-file-ref-check (make refcheckdocs).

Subject: [PATCH 3861/5214] leds: as3668: Fix Kconfig symbol name mismatch in
 Makefile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

kconfiglint reports:

  X001: CONFIG_LEDS_AS3668 referenced in Makefile but not defined
        in any Kconfig

The AS3668 LED driver was introduced in
commit c7dd343a3756 ("leds:
as3668: Driver for the ams Osram 4-channel i2c LED driver").
That commit defined the Kconfig symbol as LEDS_OSRAM_AMS_AS3668 in
drivers/leds/Kconfig but used the shorter name LEDS_AS3668 in the
Makefile's obj-* line.

Because the Makefile references CONFIG_LEDS_AS3668 which does not exist,
the driver can never be built — the obj-* line always evaluates to
obj- += leds-as3668.o (empty config), so the object file is never
compiled regardless of what the user selects in menuconfig.

Fix the Makefile to reference the correct Kconfig symbol
CONFIG_LEDS_OSRAM_AMS_AS3668, matching what is defined in
drivers/leds/Kconfig.

Subject: [PATCH 3864/5214] Documentation: leds: leds-class: Document keyboard
 backlight LED class naming

Document the existing practice of always using 'kbd_backlight' for
the function part of LED class device names for LED class devices which
control single-zone keyboard backlights.

Also extend this existing practice with a new naming scheme for keyboards
with zoned backlight control. There are several drivers in the works (see
the Link:tags below) which offer backlight control for keyboards where
the keyboard backlight is divided in a limited number of zones, e.g.
"main", "cursor" and "numpad" zones.

It is important to agree on a consistent naming scheme for these now,
so that userspace can support multiple different models / vendors through
a single unified naming scheme.

+Keyboard backlight control LED Device Naming
+============================================
+
+For backlit keyboards with a single brightness / color settings a single
+(multicolor) LED class device should be used to allow userspace to change
+the backlight brightness (and if possible the color). This LED class device
+must use "kbd_backlight" for the function part of the LED class device name.
+IOW the name must end with ":kbd_backlight".
+
+For backlit keyboards with multiple control zones, one (multicolor) LED class
+device should be used per zone. These LED class devices' name must follow:
+
+	"<devicename>:<color>:kbd_zoned_backlight-<zone_name>"
+
+and <devicename> must be the same for all zones of the same keyboard.
+
+<zone_name> should be descriptive of which part of the keyboard backlight
+the zone covers and should be suitable for userspace to show to an end user
+in an UI for controlling the zones.
+
+Where possible <zone_name> should be a value already used by other
+zoned keyboards with a similar or identical zone layout, e.g.:
+
+<devicename>:<color>:kbd_zoned_backlight-right
+<devicename>:<color>:kbd_zoned_backlight-middle
+<devicename>:<color>:kbd_zoned_backlight-left
+<devicename>:<color>:kbd_zoned_backlight-corners
+<devicename>:<color>:kbd_zoned_backlight-wasd
+
+or:
+
+<devicename>:<color>:kbd_zoned_backlight-main
+<devicename>:<color>:kbd_zoned_backlight-cursor
+<devicename>:<color>:kbd_zoned_backlight-numpad
+<devicename>:<color>:kbd_zoned_backlight-corners
+<devicename>:<color>:kbd_zoned_backlight-wasd
+
+Note that this is intended for keyboards with a limited number of zones,
+keyboards with per key addressable backlighting must not use LED class devices
+since the sysfs API is not suitable for rapidly change multiple LEDs in one
+"commit" as is necessary to do animations / special effects on such keyboards.
+
+An exception to the rule that all zones must follow:
+
+	"<devicename>:<color>:kbd_zoned_backlight-<zone_name>"
+
+is made for the special case where there is a single big zone which controls
+the backlighting of almost all of the keyboard and there are some small areas
+with separate control, like just the 4 cursor keys, or the WASD keys. In this
+case the main zone should use 'kbd_backlight' for the function part of the name
+for compatibility with (older) userspace code which is not aware of
+the "kbd_zoned_backlight-<zone_name>" function naming scheme.
+
+While the smaller zones should use the new zoned naming scheme. Such a setup
+would result in e.g.:
+
+<devicename>:<color>:kbd_backlight
+<devicename>:<color>:kbd_zoned_backlight-wasd
+
+"kbd_zoned_backlight-<zone_name>" aware userspace should be aware of this
+exception and check for a main zone with a "kbd_backlight" function-name.

From a6ec318b16f8e6b91867d0cfce22cb8b8b665eeb Mon Sep 17 00:00:00 2001
From: Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com>
Date: Tue, 5 May 2026 12:28:45 +0200
Subject: [PATCH 3866/5214] leds: bcm63138/cros_ec: Move MODULE_DEVICE_TABLE
 next to the table itself
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it
exports, because this is easier to read and verify.  It also makes more
sense since #ifdef for ACPI or OF could hide both of them.

Most of the privers already have this correctly placed, so adjust
the missing ones.  No functional impact.

+description:
+  The LM3560 is a 2-MHz fixed frequency synchronous boost converter with two
+  1000-mA constant current drivers for high-current white LEDs. The dual high-
+  side current sources allow for grounded cathode LED operation and can be
+  tied together for providing flash currents at up to 2 A through a single LED.
+  An adaptive regulation method ensures the current for each LED remains in
+  regulation and maximizes efficiency.

Subject: [PATCH 3868/5214] leds: Introduce the multi_max_intensity sysfs
 attribute

Some multicolor LEDs support global brightness control in hardware,
meaning that the maximum intensity of the color components is not
connected to the maximum global brightness. Such LEDs cannot be
described properly by the current multicolor LED class interface,
because it assumes that the maximum intensity of each color component
is described by the maximum global brightness of the LED.

Fix this by introducing a new sysfs attribute called
"multi_max_intensity" holding the maximum intensity values for the
color components of a multicolor LED class device. Drivers can use
the new max_intensity field inside struct mc_subled to tell the
multicolor LED class code about those values. Intensity values written
by userspace applications will be limited to this maximum value.

Drivers for multicolor LEDs that do not support global brightness
control in hardware might still want to use the maximum global LED
brightness supplied via devicetree as the maximum intensity of each
individual color component. Such drivers should set max_intensity
to 0 so that the multicolor LED core can act accordingly.

The lp50xx and ncp5623 LED drivers already use hardware-based control
for the global LED brightness. Modify those drivers to correctly
initalize .max_intensity to avoid being limited to the maximum global
brightness supplied via devicetree.

Subject: [PATCH 3869/5214] leds: dac124s085: Declare SPI command word as
 __le16

dac124s085_set_brightness() builds a 16-bit SPI command word:

	u16 word;
	...
	word = cpu_to_le16(((led->id) << 14) | REG_WRITE_UPDATE |
			   (brightness & 0xfff));
	ret = spi_write(led->spi, (const u8 *)&word, sizeof(word));

cpu_to_le16() returns __le16, but the local 'word' is declared as
plain u16, which sparse flags:

  drivers/leds/leds-dac124s085.c:42:14: warning: incorrect type in
  assignment (different base types)

The bytes that hit the wire are correct because cpu_to_le16() does
the right thing on either endianness, but mixing the annotated and
unannotated types defeats sparse's __bitwise checking and would let
a future reader treat the buffer as a host-endian u16 by mistake.

Declare 'word' as __le16 to match how it is built and consumed.

No functional change.

Subject: [PATCH 3870/5214] leds: Adjust documentation of brightness sysfs node

Adjust documentation of brightness sysfs node about accepted value range.
The code accepts only decimal values. We may not relax that due to different
readings for, e.g., octal 0100, which becomes 64 instead of currently parsed
100.

Subject: [PATCH 3871/5214] leds: core: Fix race condition for software blink

led_set_brightness() function: Change handling of software blink to
avoid race conditions when stopping blink and setting brightness.

Triggers may call led_set_brightness(LED_OFF),
led_set_brightness(LED_FULL) in quick succession to disable blinking and
turn the LED on. If the delayed work task has not yet disabled blinking
by the time the second call occurs, then the brightness also needs to be
changed in the delayed work task.

Subject: [PATCH 3873/5214] leds: flash: Add support for Samsung S2M series
 PMIC flash LED device

Add support for flash LEDs found in certain Samsung S2M series PMICs.
The device has two channels for LEDs, typically for the back and front
cameras in mobile devices. Both channels can be independently
controlled, and can be operated in torch or flash modes.

The driver includes initial support for the S2MU005 PMIC flash LEDs.

Subject: [PATCH 3874/5214] leds: rgb: Add support for Samsung S2M series PMIC
 RGB LED device

Add support for the RGB LEDs found in certain Samsung S2M series PMICs.
The device has three LED channels, controlled as a single device. These
LEDs are typically used as status indicators in mobile phones.

The driver includes initial support for the S2MU005 PMIC RGB LEDs.

+======================================
+Samsung S2M Series PMIC RGB LED Driver
+======================================
+
+Description
+-----------
+
+The RGB LED on the S2M series PMIC hardware features a three-channel LED that
+is grouped together as a single device. Furthermore, it supports 8-bit
+brightness control for each channel. This LED is typically used as a status
+indicator in mobile devices. It also supports various parameters for hardware
+patterns.
+
+The hardware pattern can be programmed using the "pattern" trigger, using the
+hw_pattern attribute.
+
+/sys/class/leds/<led>/repeat
+----------------------------
+
+The hardware supports only indefinitely repeating patterns. The repeat
+attribute must be set to -1 for hardware patterns to function.
+
+/sys/class/leds/<led>/hw_pattern
+--------------------------------
+
+Specify a hardware pattern for the RGB LEDs.
+
+The pattern is a series of brightness levels and durations in milliseconds.
+There should be only one non-zero brightness level. Unlike the results
+described in leds-trigger-pattern, the transitions between on and off states
+are smoothed out by the hardware.
+
+Simple pattern::
+
+    "255 3000 0 1000"
+
+    255 -+ ''''''-.                     .-'''''''-.
+         |         '.                 .'           '.
+         |           \               /               \
+         |            '.           .'                 '.
+         |              '-.......-'                     '-
+      0 -+-------+-------+-------+-------+-------+-------+--> time (s)
+         0       1       2       3       4       5       6
+
+As described in leds-trigger-pattern, it is also possible to use zero-length
+entries to disable the ramping mechanism.
+
+On-Off pattern::
+
+    "255 1000 255 0 0 1000 0 0"
+
+    255 -+ ------+       +-------+       +-------+

Subject: [PATCH 3878/5214] leds: uleds: Return -EFAULT on copy_to_user()
 failure

uleds_read() copies the current brightness value to userspace but
ignores copy_to_user() failures. It then clears the pending update and
reports a successful full read even when no data was copied.

Return -EFAULT when the copy fails and leave the update pending so a
later read can retry.

Subject: [PATCH 3879/5214] leds: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace and commas.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

From c19fe864f667afc49d1391d764e20b66555bcf7a Mon Sep 17 00:00:00 2001

Date: Mon, 25 May 2026 01:55:53 +0200
Subject: [PATCH 3880/5214] leds: uleds: Fix potential buffer overread

The name string supplied by userspace is not guaranteed to be
null-terminated, so using strchr() on it might result in a buffer
overread. The same thing will happen when said string is used by
the LED class device.

Fix this by using strnchr() instead and explicitly check that
the name string is properly null-terminated.

Subject: [PATCH 3883/5214] mfd: tps65910: Add error handling for dummy I2C
 transfer in probe

In tps65910_i2c_probe(), a dummy I2C transfer is performed to work
around silicon erratum SWCZ010. However, the return value of
i2c_master_send() is not checked.

If this dummy transfer fails, the driver continues execution without
detecting the error. This may lead to subsequent I2C operations also
failing, but the driver would incorrectly report success.

Add proper return value checking for the dummy I2C transfer. If the
transfer fails, log the error and return an appropriate error code
to the caller.

Subject: [PATCH 3884/5214] leds: tps6131x: Increase overvoltage protection
 threshold to 6V

Currently, there may be cases where the overvoltage detection is triggered
even with a valid and generally functioning hardware setup. This occurs,
for example, when the input voltage exceeds the currently used overvoltage
threshold of 4.65V (typical). Since input voltages up to 5V are supported,
the threshold should be adjusted accordingly.

While the target output voltage setting has no effect on the LED operation
used here, it indirectly selects the threshold for overvoltage detection.
Set this to a value of 4.95V to select a threshold of 6V (typical).

Subject: [PATCH 3885/5214] mfd: tps65219: Make poweroff handler conditional on
 system-power-controller

Currently, the TPS65219 driver unconditionally registers a poweroff
handler. This causes issues on systems where a different component
(such as TF-A firmware) should handle system poweroff instead.

Make the poweroff handler registration conditional based on the
"system-power-controller" device tree property. This follows the
standard kernel pattern where only the designated power controller
registers for system poweroff operations.

On systems where the property is absent, the PMIC will not register
a poweroff handler, allowing other poweroff mechanisms to function.

Content-Transfer-Encoding: 8bit

To allow instantiating subdevices such as the regulator and poweroff
devices that do not have corresponding device tree nodes with a
"compatible" property, use devm_mfd_add_devices() with MFD cells instead
of devm_of_platform_populate(). Since different PMICs in the SC27xx
series contain different components, use separate MFD cell tables for
each PMIC model. Define cells for all components that have upstream
drivers at this point.

From 9adbe53e32cdf3785cf71e27962282c628e97f5c Mon Sep 17 00:00:00 2001
From: Alexey Charkov <alchark@flipper.net>
Date: Tue, 31 Mar 2026 19:43:46 +0400
Subject: [PATCH 3890/5214] mfd: bq257xx: Add BQ25792 support

Add register definitions and a new 'type' enum to be passed via MFD
private data to support the BQ25792, which is a newer variant of the
BQ257xx family.

BQ25792 shares similar logic of operation with the already supported
BQ25703A but has a completely different register map and different
electrical constraints.

Subject: [PATCH 3891/5214] mfd: sm501: Fix reference leak on failed device
 registration

When platform_device_register() fails in sm501_register_device(), the
embedded struct device in pdev has already been initialized by
device_initialize(), but the failure path only reports the error and
returns without dropping the device reference for the current platform
device:

  sm501_register_device()
    -> platform_device_register(pdev)
       -> device_initialize(&pdev->dev)
       -> setup_pdev_dma_masks(pdev)
       -> platform_device_add(pdev)

This leads to a reference leak when platform_device_register() fails.
Fix this by calling platform_device_put() before returning the error.

The issue was identified by a static analysis tool I developed and
confirmed by manual review.

Subject: [PATCH 3892/5214] mfd: cros_ec: Don't add cros_ec_ucsi if it is
 defined in OF or ACPI

On devices with a UCSI PPM in the EC, check for cros_ec_ucsi to be
defined in the OF device tree or an ACPI node. If it is defined by
either OF or ACPI, it does not need to be added as a subdevice of
cros_ec_dev mfd. cros_ec_ucsi will load from the OF or ACPI node.

The RZ/G3{E,L} SoCs have an LVDS Common (LVDS_CMN) region which is common
to all LVDS channels. The RZ/G3L has single-link, but the RZ/G3E has both
single and dual-link.

Use the syscon interface to access these registers for scalability.

Subject: [PATCH 3895/5214] dt-bindings: mfd: hisilicon,hi655x-pmic: Convert to
 DT schema

Convert the Hisilicon Hi655x PMIC binding from the text format to DT schema
to enable dtbs_check validation.

The 'regulators' child node is added based on existing usage in
arch/arm64/boot/dts/hisilicon/hi6220-hikey.dts, which defines child
regulator nodes not documented in the original .txt binding.

The uppercase LDO names are retained to match existing DTS usage.

Subject: [PATCH 3896/5214] mfd: MAINTAINERS: Remove Krzysztof from Samsung
 PMIC drivers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Due to lack of time I did not perform reviews of patches for Samsung
PMIC drivers last year, at least not in timely manner.  I still can
perform limited testing of the code on hardware, but that does not
warrant having "M" here.

Maintainer should be responsive, so drop my name and shift these drivers
maintenance to André Draszik (from previous reviewer role).

Subject: [PATCH 3897/5214] mfd: rsmu: Fix page register setup

Fix writes to page register in 8A3400x family (Clock Matrix).

All calls to rsmu_write_page_register() (both in i2c and spi) have
resulted in early return, because all addresses in
include/linux/mfd/idt8a340_reg.h are less than RSMU_CM_SCSR_BASE.

There were 2 separate patch series which have to be merged in one time:
mfd and ptp. The latter have been merged, the former[1] have not.

Subject: [PATCH 3899/5214] mfd: Consistently define pci_device_ids using named
 initializers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The various struct pci_device_id arrays were initialized mostly by one
of the PCI_DEVICE macros and then list expressions. The latter isn't
easily readable if you're not into PCI. Using named initializers is more
explicit and thus easier to parse.

The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.

This change doesn't introduce changes to the compiled pci_device_id
arrays. Tested on x86 and arm64.

Subject: [PATCH 3900/5214] mfd: cs5535: Add, assign and expose the software
 node for the GPIO cell

There are board files in-tree that want to request GPIOs from this chip.
They currently rely on the GPIO core's mechanism of matching software
nodes' labels against GPIO controller names. We want to remove this
behavior from the kernel and to this end, we need to associate the
referenced GPIO controller with its target software node.

Create a dedicated GPIO software node for cs5535, assign it to the GPIO
cell and expose its address in a new header.

We only expose a single software node instance but that's alright: all
existing hardware only contains a single cs5535 companion and the geode
board file for which we expose this is legacy anyway.

Subject: [PATCH 3901/5214] mfd: wm8994: Remove dead legacy-gpio code

The old-style gpio handling in wm8994 came from a commit 7c8844481a1c
("mfd: wm8994: Emulate level triggered interrupts if required") in
linux-3.11, but nothing in the kernel ever set the 'irq_gpio' member
in the wm8994_pdata structure, so this was always dead code.

Remove it now to reduce the dependency on the legacy gpio interfaces.

Subject: [PATCH 3902/5214] mfd: max77759: Improve static struct formatting and
 commentary

Improve code style. This includes the following:
- Formatting the max77759_chgr_irqs entries to fit in a single line
  instead of breaking them into multiple lines to improve readability.

- Refactoring comments such that they're full sentences and have
  punctuation marks for a couple of macro definitions to adhere to the
  documentation style.

- Explicitly initializing `MAX77759_CHGR_MODE_OFF`.

Inline the i2c_check_functionality() check, since the function returns a
boolean status rather than an error code.

Subject: [PATCH 3906/5214] mfd: ezx-pcap: Remove unused driver

Support for the Motorola EZX phones based on Intel PXA processors was
removed in 2022, but this driver remained present in the tree. As far
as I can tell, the support was never quite functional upstream because
the board files did not actually instantiate the SPI device for the PCAP.

There are still also drivers for the various mfd cells: keys, touchscreen,
regulator and rtc, all of which are obviously orphaned as well but can
be removed separately as the Kconfig dependency now prevents them from
being enabled.

From 2611c4d623ba867e196a4146f1927c3c468ac2bc Mon Sep 17 00:00:00 2001

Subject: [PATCH 3907/5214] dt-bindings: mfd: aspeed,ast2x00-scu: Describe
 AST2700 SCU0

AST2700 consists of two interconnected SoC instances, each with its own
System Control Unit (SCU). The SCU0 provides pin control, interrupt
controllers, clocks, resets, and address-space mappings for the
Secondary and Tertiary Service Processors (SSP and TSP).

Describe the SSP/TSP address mappings using the standard
memory-region and memory-region-names properties.

Disallow legacy child nodes that are not present on AST2700, including
p2a-control and smp-memram. The latter is unnecessary as software can
access the scratch registers via the SCU syscon.

Also allow the AST2700 SoC0 pin controller to be described as a child
node of the SCU0, and add an example illustrating the SCU0 layout,
including reserved-memory, interrupt controllers, and pinctrl.

Subject: [PATCH 3908/5214] mfd: cros_ec: Delay dev_set_drvdata() until probe
 success

If ec_device_probe() fails, cros_ec_class_release releases memory for the
cros_ec_dev structure. However, because the drvdata was already set,
sub-drivers like cros_ec_typec can still retrieve the stale pointer via the
platform device. This leads to a use-after-free when cros_ec_typec attempts
to access &typec->ec->ec->dev on a device that has already been released.
Move dev_set_drvdata() to ensure that the pointer is only made available
once all initialization steps have succeeded.

Currently the code checks if a firmware was received, however it does
not verify that the firmware size is larger than the firmware header. As
the firmware pointer is dereferenced as a pointer to the header
structure this could lead to an out of bounds memory access. Add the
missing check.

Subject: [PATCH 3914/5214] mfd: max77620: Convert poweroff support to sys-off
 API

Convert max77620_pm_power_off() to the sys-off callback prototype and
register it with the sys-off API when the device tree marks the PMIC as
a system power controller. This also removes the global max77620_scratch
pointer by passing the chip instance through the callback data.

This modernizes the driver's poweroff handling and aligns it with
the kernel sys-off infrastructure.

The msm8960 RPM resource table is missing the QDSS clock entry (resource
ID 209) that is present in the android-msm-mako-3.4 downstream kernel.
Add it so that RPM clock initialization succeeds.

Subject: [PATCH 3918/5214] mfd: twl4030-power: Update checks for specific
 boards to use the DT

The twl4030-power driver contains two checks for ARM machine IDs via
machine_is_*() macros. The two boards concerned now support only FDT
booting, which does not use machine IDs, and therefore the code should
be updated to check the DT compatible property instead.
The legacy board files for these machines were removed in
commit 1b383f44aabc ("ARM: OMAP2+: Drop board file for 3430sdp") and
commit e92fc4f04a34 ("ARM: OMAP2+: Drop legacy board file for LDP").
The presence of these machine ID checks prevents the removal of machine
IDs no longer used by the kernel from arch/arm/tools/mach-types,
because the machine_is_*() macros are generated from mach-types. To
resolve this issue, use of_machine_is_compatible() instead.

Subject: [PATCH 3920/5214] mfd: tps6586x: Fix OF node refcount

Platform devices created with platform_device_alloc() call
platform_device_release() when the last reference to the device's
kobject is dropped. This function calls of_node_put() unconditionally.
This works fine for devices created with platform_device_register_full()
but users of the split approach (platform_device_alloc() +
platform_device_add()) must bump the reference of the of_node they
assign manually. Add the missing call to of_node_get().

Subject: [PATCH 3926/5214] dt-bindings: mfd: st,stmpe: Add missing properties
 for PWM subnode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The st,stmpe-pwm binding is already covered by the MFD schema in
Documentation/devicetree/bindings/mfd/st,stmpe.yaml. However, the
PWM subnode was missing a 'required' properties block. This allowed
Device Tree nodes to pass validation even if the 'compatible'
string was omitted. This omission could lead to probe failures
at runtime.

Fix the schema by adding the missing 'required' block.

Subject: [PATCH 3927/5214] dt-bindings: mfd: syscon: Revert
 renesas,r9a08g046-lvds-cmn

Revert commit 51284d8b1dbc ("dt-bindings: mfd: syscon: Document the
LVDS_CMN syscon for the RZ/G3L") because it is completely not matching
reality and clearly incorrect in respect of renesas,r9a08g046-lvds-cmn.

It wasn't ever build-tested by author on their DTS, either.

The documented renesas,r9a08g046-lvds-cmn compatible clearly disallows
any children and simple-mfd fallback, however its only use in original
patchset is with simple-mfd and children, so this could have never
worked.

Subject: [PATCH 3928/5214] perf machine: Propagate machine__init() error to
 callers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

machine__init() always returns 0 even when memory allocation fails,
because commit 81f981d7ec43ed93 ("perf machine: Free root_dir in
machine__init() error path") introduced 'int err = -ENOMEM' and an
error cleanup path but left the final 'return 0' instead of
'return err'.

Fix by returning err, check the return value in __machine__new_host()
which was ignoring it, and change machines__init() from void to int so
it too can propagate the error to perf_session__new(), aslr_tool__init()
and test callers.

The error cleanup also used zfree(&machine->kmaps), but kmaps is a
refcounted maps structure — use maps__zput() to properly drop the
reference, matching machine__exit().

Move dsos__init() and threads__init() before the first fallible
allocation (maps__new) so that machine__exit() is safe to call on
any machine struct that machine__init() touched, even on early failure.

Subject: [PATCH 3929/5214] perf machine: Use snprintf() for guestmount path
 construction

machines__findnew() and machines__create_guest_kernel_maps() use
sprintf() to build paths by prepending symbol_conf.guestmount.
Both write into PATH_MAX stack buffers, but guestmount comes from
user configuration and is not length-checked.  A guestmount path
at or near PATH_MAX causes a stack buffer overflow.

Switch to snprintf() with sizeof() to prevent overflow.  The
subsequent access()/fopen() calls will fail on a truncated path.

Subject: [PATCH 3930/5214] perf cs-etm: Validate num_cpu before metadata
 allocation

cs_etm__process_auxtrace_info_full() reads num_cpu from untrusted
perf.data and uses it to allocate the metadata pointer array:

  metadata = zalloc(sizeof(*metadata) * num_cpu);

On 32-bit, sizeof(*metadata) is 4, so num_cpu = 0x40000000 overflows
the multiplication to 0, causing zalloc(0) to return a valid zero-sized
allocation followed by out-of-bounds writes in the population loop.

Fix by computing priv_size early and using it to bound num_cpu: each
CPU needs at least one u64 metadata entry, so num_cpu cannot exceed
the total number of u64 entries in the event's private data area.

Subject: [PATCH 3931/5214] perf cs-etm: Require full global header in
 auxtrace_info size check

cs_etm__process_auxtrace_info() checks that header.size covers
event_header_size + INFO_HEADER_SIZE (16 bytes total), but then
accesses ptr[CS_PMU_TYPE_CPUS] at offset 24 from the start of the
event.  A crafted 16-byte auxtrace_info event passes the size check
but reads out-of-bounds.

Include CS_ETM_HEADER_SIZE in the minimum size check so that the
global header entries (version, pmu_type_cpus, snapshot) are
guaranteed to fit within the event.

Subject: [PATCH 3932/5214] perf cs-etm: Bounds-check CPU in
 cs_etm__get_queue()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cs_etm__get_queue() indexes etm->queues.queue_array[cpu] without
validating that cpu is within nr_queues.  When processing
AUX_OUTPUT_HW_ID events, the cpu value comes from untrusted perf.data
trace payload and flows through cs_etm__process_trace_id_v0_1() and
cs_etm__queue_aux_fragment() without bounds checking, allowing an
out-of-bounds read with a crafted file.

Add a bounds check in cs_etm__get_queue() and NULL checks in all
callers.

Also add NULL checks for queue_array[i].priv in the queue iteration
loops in cs_etm__map_trace_id_v0() and cs_etm__process_trace_id_v0_1()
— after auxtrace_queues__grow() new entries are zero-initialized so
.priv can be NULL.  Add a get_cpu_data() NULL check in
cs_etm__process_trace_id_v0_1(), matching the existing check in
cs_etm__process_trace_id_v0().

When c2c_hists__init() fails partway through hpp_list__parse(),

container without first unregistering the format entries.

on the error path, matching what c2c_he_free() already does on the

Subject: [PATCH 3934/5214] perf c2c: Fix hist entry and format list leaks in
 c2c_he_free()

c2c_he_free() calls hists__delete_entries() which only walks the
output-sorted entries tree.  During c2c resort, when cacheline entries
are merged and the redundant entry is freed, the inner hists have not
been output-resorted yet, so hists->entries is empty.  The actual inner
hist_entry objects live in entries_in_array[] and entries_collapsed,
which are never walked, leaking all inner hist_entry objects for every
merged cacheline.

Additionally, the dynamically allocated format entries on hists->list
are never unregistered or freed.

Fix both issues by switching to hists__delete_all_entries() which walks
all rb_root trees, and calling perf_hpp__reset_output_field() to clean
up format entries.

Subject: [PATCH 3935/5214] perf bpf: Validate array presence before casting
 BPF prog info pointers

Several functions cast bpf_prog_info fields (jited_ksyms,
jited_func_lens, jited_prog_insns) from u64 to pointers and
dereference them.  These fields are only valid pointers if
bpil_offs_to_addr() converted their file offsets to addresses, which
only happens when the corresponding PERF_BPIL_* bits are set in
info_linear->arrays.

A crafted perf.data can leave these bits unset while setting non-zero
counts and offset values, causing the functions to dereference raw file
offsets as pointers.

Add array bitmask validation to all perf.data processing paths:

  - __bpf_event__print_bpf_prog_info(): check JITED_KSYMS and
    JITED_FUNC_LENS (changed to take struct perf_bpil *)
  - machine__process_bpf_event_load(): check JITED_KSYMS
  - bpf_read(): check JITED_INSNS before memcpy from jited_prog_insns
  - dso__disassemble_filename(): check JITED_INSNS before returning
    jited_prog_insns pointer

Subject: [PATCH 3936/5214] perf dso: Set standard errno on decompression
 failure

dso__get_filename() sets errno to a negative custom DSO_LOAD_ERRNO
value when kernel module decompression fails:

  errno = *dso__load_errno(dso);  /* e.g. -9996 */

The caller __open_dso() then computes fd = -errno, producing a large
positive value (9996) that looks like a valid file descriptor.  This
can cause close_data_fd() to close an unrelated fd used by another
subsystem.

Set errno to EIO instead.  The detailed error code is already stored
in dso__load_errno(dso) for diagnostic messages.

Subject: [PATCH 3937/5214] ASoC: qcom: q6apm: fix NULL pointer dereference in
 graph_callback

When q6apm_free_fragments() is called it frees rx_data.buf/tx_data.buf
and sets them to NULL under graph->lock. A late DSP buffer-done response
can race with this: graph_callback() passes the !graph->ar_graph guard
(not yet NULL), acquires the lock, but then dereferences a now-NULL buf
pointer to read buf[token].phys, crashing at virtual address 0x10.

Add a NULL check for buf inside the mutex-protected section in both the
write-done (DATA_CMD_RSP_WR_SH_MEM_EP_DATA_BUFFER_DONE_V2) and
read-done (DATA_CMD_RSP_RD_SH_MEM_EP_DATA_BUFFER_V2) handlers and bail
out cleanly if buffers have already been freed.

This problem is only shown up recently while apr bus was updated to
process the commands per service rather from single global queue.

Subject: [PATCH 3938/5214] ASoC: rockchip: Drop problematic guard() changes

This reverts commit f7fe9f707360 ("ASoC: rockchip: rockchip_sai: Use
guard() for spin locks").

This is very noisy pointless churn that was not tested by the submitter,
nor was it addressed to the driver's maintainer. It mixes unrelated
whitespace changes (eliminating the blank line between the includes -
why?) with hard to review diffs that add a whole indentation level to
the function for no benefit, while also not following kernel code style
by doing stuff like "ret == 0".

The driver is better off without these changes, and they're not worth
the time to validate whether they really do make no functional changes.

Subject: [PATCH 3939/5214] ASoC: tlv320aic3x: restrict CLKDIV bypass Q values
 in dual-rate mode

The datasheet documents that when the PLL is disabled and dual-rate mode
is enabled, only Q values {4, 8, 9, 12, 16} are valid for the CLKDIV
bypass path; all other Q values produce invalid bitclock output.

The existing loop iterates Q from 2 to 17 without this restriction,
causing silent audio failure when an out-of-spec Q is picked.

Restrict the Q search to the allowed set in dual-rate mode.

Subject: [PATCH 3942/5214] rtla: Fix and clean up .gitignore

.gitignore includes several entries prone to unwanted matches in
subdirectories. One of them, the recently added "lib/", matches the
recently added directory "tests/scripts/lib/" in addition to the
intended top-level "lib/", which contains object files built from
sources in tools/lib.

Add "/" to all .gitignore entries that are intended to only match
top-level files or directories: rtla, rtla_static, unit_tests,
libsubcmd/.

Remove .gitignore entries that are not needed at all:

- lib/ (contains only object files, ignored by top-level .gitignore
  already).
- .txt rtla output files added to .gitignore in commit 02689ae385c5
  ("rtla: Add generated output files to gitignore"). Since commit
  ad5b50a0959f ("rtla/tests: Run runtime tests in temporary directory"),
  those are created in a temporary directory, not in tools/tracing/rtla.

Keeping libsubcmd/ as that contains other generated files (headers,
archives, etc.).

Subject: [PATCH 3943/5214] rtla/tests: Fix pgrep filter in
 get_workload_pids.sh

Multiple runtime tests in RTLA rely on the get_workload_pids() shell
helper function to get the PIDs of both kernel and user workloads.

On some systems (e.g. Fedora 43), pgrep matches kernel thread names
including square brackets: "[osnoise/0]"; on other systems (e.g.
RHEL 9.8), brackets are not included: "osnoise/0".

Accept both as valid workload PIDs rather that just the non-bracket form
to make the tests work on all systems.

Subject: [PATCH 3944/5214] timekeeping: Register default clocksource before
 taking tk_core.lock

Commit f24df84cbe05 ("time/jiffies: Register jiffies clocksource before
usage") moved the jiffies clocksource registration into
clocksource_default_clock(), so that it is registered lazily on the first
call. __clocksource_register() acquires clocksource_mutex, but the first
caller is timekeeping_init(), which invokes clocksource_default_clock()
while holding tk_core.lock, a raw spinlock.

Acquiring a sleeping mutex while holding a raw spinlock is invalid.

The default clocksource only has to be registered before
tk_setup_internals() consumes its mult/shift/maxadj. Neither
clocksource_default_clock(), the ->enable() callback, nor the registration
itself need tk_core.lock, so fetch and enable the clock before acquiring
the lock. This preserves the "register before usage" ordering while
keeping clocksource_mutex out of the raw spinlock section.

clocksource_default_clock() has a second caller,
clocksource_done_booting(), which invokes it with clocksource_mutex already
held. That path avoids a recursive lock because timekeeping_init() has
already run and set cs_jiffies_registered, so the registration is skipped
there. This change does not alter that; it only fixes the invalid wait
context in timekeeping_init().

Subject: [PATCH 3945/5214] posix-cpu-timers: Use u64 multiplication in
 update_rlimit_cpu()

update_rlimit_cpu() converts the RLIMIT_CPU value to nanoseconds with

        u64 nsecs = rlim_new * NSEC_PER_SEC;

On 32-bit kernels both rlim_new (unsigned long) and NSEC_PER_SEC
(1000000000L) are 32-bit, so the multiplication is performed in unsigned
long and truncated for rlim_new > 4 seconds before being widened to u64.

The same file already casts to u64 for the matching computation in
check_process_timers():

        u64 softns = (u64)soft * NSEC_PER_SEC;

As a result, the truncated value is installed into the CPUCLOCK_PROF
expiry cache (nextevt), causing the process CPU timer to be programmed
to fire prematurely for any RLIMIT_CPU soft limit >= 5 seconds. The
actual SIGXCPU/SIGKILL decision in check_process_timers() already casts
to u64 and is therefore correct, so limit enforcement is not broken;
only the expiry-cache programming is wrong. Apply the same cast here so
both paths convert rlim_cur identically.

64-bit kernels are unaffected.

Subject: [PATCH 3949/5214] cpufreq: schedutil: Fix uncleared need_freq_update
 on the .adjust_perf() path

The need_freq_update flag makes sugov_should_update_freq() return true
regardless of the rate_limit_us throttling, and is cleared in
sugov_update_next_freq(). sugov_update_single_freq() and
sugov_update_shared() go through that helper, so the flag does not
persist there.

However, sugov_update_single_perf(), used by drivers implementing the
.adjust_perf() callback (e.g. intel_pstate or amd-pstate in passive
mode) calls cpufreq_driver_adjust_perf() directly and never goes through
sugov_update_next_freq(), so the need_freq_update flag is not cleared in
that path.

Before commit 75da043d8f88 ("cpufreq/sched: Set need_freq_update in
ignore_dl_rate_limit()"), this was effectively harmless because
sugov_should_update_freq() still honored the rate limit even when
need_freq_update was set. After that change, the flag forces
sugov_should_update_freq() to always return true, so once set, it
stays effective indefinitely on the .adjust_perf() path.

As a result, cpufreq_driver_adjust_perf() gets called on every scheduler
utilization update (with the runqueue lock held) rather than being
throttled by rate_limit_us, even if the driver itself may skip redundant
hardware updates.

Clear need_freq_update at the end of the adjust_perf path as well.

Subject: [PATCH 3950/5214] drm/amdkfd: Avoid double-unpin of DOORBELL/MMIO BOs
 on free

amdgpu_amdkfd_gpuvm_free_memory_of_gpu() unpinned DOORBELL and MMIO
remap BOs (which are pinned at allocation time) before checking whether
the BO is still mapped to the GPU. When the BO is still mapped, the
function returns -EBUSY and leaves the BO alive, but it has already
been unpinned. The BO is then unpinned again when it is finally freed
during process teardown, triggering a ttm_bo_unpin() underflow warning:

  WARNING: CPU: 18 PID: 15066 at ttm/ttm_bo.c:650 amdttm_bo_unpin+0x6d/0x80 [amdttm]

Move the unpin after the mapped_to_gpu_memory check so it only happens
once we are committed to freeing the BO.

 PrepareMp1ForUnload on SMU V15 APUs

During smu_v15_0_0_system_features_control(), the driver sends a
PrepareMp1ForUnload message to PMFW. PMFW then performs nBIF and SYSHUB
function-level resets (FLR), disabling PCIe CFG space reset, which
clears the framebuffer enable bit to zero and disables MC (memory controller)
access from the host.

Re-enable MC access via the nbio mc_access_enable callback right after
PrepareMp1ForUnload completes in smu_v15_0_0_system_features_control().

Subject: [PATCH 3953/5214] drm/amdkfd: Properly acquire queue buffers in CRIU
 restore

When kfd_queue_acquire_buffers() was split off from
set_queue_properties_from_user(), set_queue_properties_from_criu()
was missed. Thus, set_queue_properties_from_criu() is not
filling out the buffer fields of queue_properties, which
can come up when subsequent code expects them to be non-null.

Add the proper call to kfd_queue_acquire_buffers(), and also
use the right cast types in set_queue_properties_from_criu()
(which were missed at the same time)

Subject: [PATCH 3954/5214] drm/amdgpu: skip already suspended IP blocks in
 ip_suspend_phase2

The GPU reload test (S3 / mode1 reset / module reload) triggers a
WARN_ON in amdgpu_irq_put() on gfx10 when unloading amdgpu:

  WARNING: CPU: 0 PID: 2314 at amd/amdgpu/amdgpu_irq.c:676 amdgpu_irq_put+0xc3/0xe0 [amdgpu]
  Call Trace:
   gfx_v10_0_hw_fini+0x41/0x150 [amdgpu]
   amdgpu_ip_block_hw_fini+0x29/0xc0 [amdgpu]
   amdgpu_device_fini_hw+0x315/0x610 [amdgpu]
   amdgpu_driver_unload_kms+0x7c/0x90 [amdgpu]
   amdgpu_pci_remove+0x51/0x90 [amdgpu]

amdgpu_device_ip_resume_phase2() skips IP blocks whose status.hw is
already set, but amdgpu_device_ip_suspend_phase2() never had the
matching guard, so a block can be suspended twice (e.g. a reset or
recovery issued while the device is already suspended).  The second
suspend runs hw_fini again, which now releases the gfx fault IRQs
unconditionally, dropping a refcount that is already zero and tripping
the WARN_ON in amdgpu_irq_put().

The fault/EOP IRQ get/put were balanced through late_init/hw_fini
before, which masked the double-suspend; moving the get into hw_init
made the suspend/resume asymmetry visible as an IRQ refcount underflow.

Honor status.hw in ip_suspend_phase2() so suspend mirrors resume and a
block is only torn down once.

[Why]
Some 8K displays cannot tolerate the reduced phy ssc value
at high link utilization and show corruption or black screen.

[How]
Add an EDID panel-id quirk to utilize existing skip_phy_ssc_reduction flag.

To pass the link into the quirk handler, change the signature of
apply_edid_quirks() to take link as an argument. The dev local in
dm_helpers_parse_edid_caps() becomes unused and is removed.

Subject: [PATCH 3956/5214] drm/amd/display: Restore periodic detection for
 DCN35

[Why&How]
Periodic detection callbacks from DCN35 was removed for higher IPS
residency causing some displays to fail to recover after DPMS sleep. The
monitors bounces HPD ~1.2s after link training, and without periodic
detection the system enters IPS with no mechanism to wake and rediscover
the display.

Restore the periodic detection calls in dcn35_clk_mgr for now. It should
be replaced with a proper IPS-aware solution long term using DMUB.

Also remove it from dcn31 and dcn314_clk_mgr.c since they do not have IPS,
thus should not affect them.

Subject: [PATCH 3957/5214] drm/amdkfd: Fix SMI event PID reporting for
 containers

SMI events were reporting incorrect PIDs in containerized environments,
causing test failures where container processes expected to see their
namespace-local PIDs but instead received global host PIDs.

The issue had two root causes:

1. Event functions were called from kernel context (page fault handlers,
   migration workers) where 'current' refers to the kernel worker thread,
   not the userspace GPU process that triggered the event.

2. PID conversion used task_tgid_vnr() which returns the PID in the
   caller's namespace (init namespace for kernel threads), not the task's
   own namespace.

This patch updates the SMI event interface:

- Change 8 event function signatures to accept task_struct pointer
  instead of pid_t, allowing proper namespace-aware PID conversion

- Convert PIDs using task_tgid_nr_ns(task, task_active_pid_ns(task))
  which returns the PID as the process sees it via getpid()

- Update 10 call sites to pass p->lead_thread (the GPU process)
  instead of p->lead_thread->pid or current (kernel worker)

This ensures SMI events report container-local PIDs, which is critical
for containerized GPU workloads to correctly correlate events with their
processes.

Subject: [PATCH 3959/5214] drm/amdgpu/gfx: fix cleaner shader IB buffer
 overflow

The cleaner shader sysfs path allocates a 16-dword (64 byte) IB but
incorrectly fills (align_mask + 1) dwords. On GFX rings align_mask is
0xff, so the loop wrote 256 dwords into a 64-byte buffer, causing a
kernel page fault.

The IB only needs to be a minimal NOP shell to schedule the job; the
cleaner shader itself is emitted on the ring via emit_cleaner_shader().
Fill 16 dwords to match the allocation.

v2: Use ib_size_dw variable (Lijo)

Subject: [PATCH 3960/5214] drm/amd/display: Add IN_FORMATS_ASYNC support for
 planes

[Why]
The DRM core exposes an IN_FORMATS_ASYNC plane property describing the
set of format/modifier pairs that are valid for asynchronous (immediate)
page flips. amdgpu already advertises async page flip support via
mode_config.async_page_flip = true, but never implemented the
.format_mod_supported_async plane callback, so the IN_FORMATS_ASYNC
property was not created.

This inconsistency (advertising async flips while exposing IN_FORMATS but
no IN_FORMATS_ASYNC) causes userspace, such as igt-gpu-tools, to emit a
repeated warning during plane initialization, which in turn demotes many
otherwise passing KMS subtests to a WARN result.

[How]
Wire up .format_mod_supported_async to the existing
amdgpu_dm_plane_format_mod_supported callback so the async format list is
populated. amdgpu does not restrict async flips at the format/modifier
level: the async flip constraints are enforced at atomic check and commit
time and only require a fast update (no change to FB pitch, DCC state,
rotation or memory type) between the old and new buffers. Therefore the
set of formats/modifiers valid for async flips is identical to the
regular IN_FORMATS set, and the same callback can be reused.

Subject: [PATCH 3961/5214] drm/amd/display: Fix mem_type change detection for
 async flips

[Why]
amdgpu_dm_crtc_mem_type_changed() fetches the "old" and "new" plane state
with two drm_atomic_get_plane_state() calls, which both return the new
state. It compares a state against itself, so it never detects a mem_type
change and never rejects the async flip.

On DCN 3.0.1, this shows up as intermittent corruption when a single DCC
plane is scanned out with immediate flips under gamescope and its buffer
moves between the VRAM carveout and GTT.

[How]
Use drm_atomic_get_old_plane_state() and drm_atomic_get_new_plane_state()
to compare the actual old and new states. These return NULL rather than
an error pointer for a plane that is not part of the commit, so the
IS_ERR() check becomes a NULL check that skips those planes, such as an
unmodified cursor still in the CRTC's plane_mask.

Subject: [PATCH 3962/5214] drm/radeon: fix r100_copy_blit for large BOs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

r100_copy_blit() copies BOs as 1024-pixel-wide ARGB8888 blits, so one
GPU page becomes one blit row. Large copies are split into chunks of at
most 8191 rows.

The kernel register header names the packet coordinate dwords SRC_Y_X
and DST_Y_X. In the BITBLT_MULTI description in
R5xx_Acceleration_v1.5.pdf docs, these correspond to [SRC_X1 | SRC_Y1]
and [DST_X1 | DST_Y1], which are signed 13-bit coordinates in the
-8192..8191 range. The old code kept SRC/DST_PITCH_OFFSET at the BO base
and used SRC_Y_X/DST_Y_X as the chunk address, so large BO moves could
exceed that coordinate range.

Compute per-chunk SRC/DST_PITCH_OFFSET bases and emit zero source and
destination coordinates. r100_copy_blit() already packs
SRC/DST_PITCH_OFFSET as pitch plus base offset, so large chunk addresses
belong there rather than in the coordinate fields.

This fixes Prison Architect corruption with 4096x4096 mipped textures
after they are evicted to GTT under memory pressure on RV530.

Subject: [PATCH 3963/5214] drm/amdkfd: fix list_del corruption in
 kfd_criu_resume_svm

The cleanup tail of kfd_criu_resume_svm() walks
svms->criu_svm_metadata_list and kfree()s each struct criu_svm_metadata
without removing it from the list. The list head is left pointing at
freed kmalloc-96 objects.

A second AMDKFD_IOC_CRIU_OP from the same process re-enters: list_empty()
reads the dangling ->next (use-after-free), the loop walks freed entries,
and each is kfree()'d again (double-free). This is reachable by an
unprivileged render-group user via /dev/kfd with no capabilities required.

Add list_del() before the kfree() so the list is properly emptied. The
list_for_each_entry_safe() iterator already caches the next pointer, so
unlinking during the walk is safe.

Subject: [PATCH 3964/5214] drm/amdgpu: initialize irq.lock spinlock earlier

If there is an early failure during amdgpu probe, like missing firmware, it
will end up calling amdgpu_irq_disable_all, which takes irq.lock spinlock
without it being initialized.

Initializing irq.lock earlier at amdgpu_device_init fixes the issue.

Subject: [PATCH 3965/5214] drm/amdgpu: check amdgpu_vm_bo_find() result in
 GET_MAPPING_INFO

The AMDGPU_GEM_OP_GET_MAPPING_INFO path of amdgpu_gem_op_ioctl() looks
up the bo_va for the buffer object in the caller's VM via
amdgpu_vm_bo_find(), but uses the returned pointer without checking it.

amdgpu_vm_bo_find() returns NULL when the BO has no bo_va in that VM,
which is the normal case for a BO that has never been mapped. The result
is fed straight into amdgpu_vm_bo_va_for_each_valid_mapping(), which
expands to list_for_each_entry(mapping, &(bo_va)->valids, list) and
dereferences bo_va, causing a NULL pointer dereference.

This is reachable by any process able to issue the ioctl (render group)
simply by requesting mapping info for an unmapped BO.

Return -ENOENT when no bo_va is found, jumping to out_exec so the
drm_exec context and GEM object reference are released.

Subject: [PATCH 3966/5214] drm/amdgpu: validate CP_GFX_SHADOW chunk size in CS
 pass1

Add a minimum-length check for the AMDGPU_CHUNK_ID_CP_GFX_SHADOW chunk in
amdgpu_cs_pass1(), matching the gate already present for the IB, FENCE and
BO_HANDLES chunk types.

The CP_GFX_SHADOW case previously shared a bare break with the dependency
and syncobj chunk types, which do not dereference a fixed-size struct. When
userspace submits this chunk with length_dw == 0, vmemdup_array_user() is
called with size 0 and returns ZERO_SIZE_PTR, which passes the IS_ERR()
check. amdgpu_cs_p2_shadow() then dereferences chunk->kdata as a struct
drm_amdgpu_cs_chunk_cp_gfx_shadow (reading shadow->flags), faulting on the
ZERO_SIZE_PTR and causing a NULL-pointer dereference.

This is reachable by an unprivileged process in the render group. Reject
undersized chunks with -EINVAL during pass1 so the bad submission is
rejected before pass2 ever dereferences the data.

Subject: [PATCH 3967/5214] drm/amdkfd: Fix NULL deref during sysfs teardown

Move kfd_process_remove_sysfs() earlier in kfd_process_wq_release() so
that all sysfs/procfs entries are removed before tearing down PDDs and
dropping lead_thread. The per-process sysfs attributes are backed by
struct kfd_process_device, and their show/store callbacks dereference
PDD fields. Since sysfs removal waits for active callbacks to complete,
removing these entries first closes a race where userspace reads sdma_*
and stats_* files after PDD teardown.

Previously this cleanup ran after kfd_process_destroy_pdds(), which
resets p->n_pdds to 0. This meant kfd_process_remove_sysfs() could no
longer walk the PDD array, so the per-PDD sysfs cleanup did not run as
intended.

This race caused NULL pointer dereferences observed in
kfd_sdma_activity_worker and kfd_procfs_stats_show.

Also harden kfd_process_remove_sysfs() against partially
initialized or already-freed objects:
- Check kobj_queues before removing PASID and deleting it
- Guard kobj_stats and kobj_counters before use

These checks prevent invalid dereferences during cleanup.

UTS_RELEASE evaluates to a static string and changes quite easily (e.g.
uncommitted changes in the source tree or new commits). So when checking
if a patch introduces changes to the resulting binary each usage of
UTS_RELEASE is source of annoyance.

Instead of using UTS_RELEASE directly use init_utsname()->release which
evaluates to the same string but with that a change of UTS_RELEASE
doesn't affect amdgpu_dev_coredump.o.

Subject: [PATCH 3969/5214] drm/amdgpu: convert amdgpu_vm_lock_by_pasid() to
 drm_exec
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

amdgpu_vm_lock_by_pasid() looks up a VM by PASID and reserves its root
PD with a bare amdgpu_bo_reserve(), returning the still-reserved root to
the caller. A caller that then needs to reserve further BOs (for example
the devcoredump IB dump) ends up nesting reservation_ww_class_mutex
acquires without a ww_acquire_ctx, which lockdep flags as recursive
locking.

Convert the helper to take a drm_exec context and lock the root PD with
drm_exec_lock_obj(). Callers now run it inside a
drm_exec_until_all_locked() loop and can lock additional BOs in the same
ww ticket, so there is no nested ww_mutex acquire.

The drm_exec context holds its own reference on the locked root BO, so
the helper no longer hands a root reference back to the caller: the
root output parameter is dropped, and the transient reference taken
across the PASID lookup is released before returning.

The only existing caller, amdgpu_vm_handle_fault(), is updated
accordingly. Its is_compute_context path, which previously dropped the
root reservation around svm_range_restore_pages() and re-took it, now
finalises the drm_exec context and re-initialises a fresh one; behaviour
is otherwise unchanged.

No functional change intended for the page-fault path.

Subject: [PATCH 3970/5214] drm/amdgpu: fix recursive ww_mutex acquire in
 amdgpu_devcoredump_format
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When dumping IB contents from a hung job, amdgpu_devcoredump_format()
acquired the VM root PD's reservation via amdgpu_vm_lock_by_pasid() and
then, for each IB, called amdgpu_bo_reserve() on the BO backing the IB.
Both reservations are reservation_ww_class_mutex objects and neither
used a ww_acquire_ctx, which trips lockdep:

  WARNING: possible recursive locking detected
  --------------------------------------------
  kworker/u128:0 is trying to acquire lock:
  ffff88838b16e1f0 (reservation_ww_class_mutex){+.+.}-{4:4},
    at: amdgpu_devcoredump_format+0x1594/0x23f0 [amdgpu]

  but task is already holding lock:
  ffff8882f82681f0 (reservation_ww_class_mutex){+.+.}-{4:4},
    at: amdgpu_devcoredump_format+0x1594/0x23f0 [amdgpu]

   Possible unsafe locking scenario:
         CPU0
         ----
    lock(reservation_ww_class_mutex);
    lock(reservation_ww_class_mutex);

   *** DEADLOCK ***
   May be due to missing lock nesting notation

  Workqueue: events_unbound amdgpu_devcoredump_deferred_work [amdgpu]
  Call Trace:
   __ww_mutex_lock.constprop.0
   ww_mutex_lock
   amdgpu_bo_reserve
   amdgpu_devcoredump_format+0x1594 [amdgpu]
   amdgpu_devcoredump_deferred_work+0xea [amdgpu]

The two reservations are on different BOs in the captured trace, so the
splat is a lockdep-correctness warning, not an observed deadlock. It
becomes a real self-deadlock whenever the IB BO shares its dma_resv with
the root PD (the always-valid case, see amdgpu_vm_is_bo_always_valid()):
amdgpu_bo_reserve(abo) re-acquires the same ww_mutex without a ticket
and blocks forever. With amdgpu.gpu_recovery=0 the timeout handler
refires every ~2 s and each invocation produces this splat, drowning the
kernel ring buffer.

Now that amdgpu_vm_lock_by_pasid() takes a drm_exec context, move the IB
dumping into a separate helper that locks the root PD and every IB BO
together in a single drm_exec ticket. DRM_EXEC_IGNORE_DUPLICATES handles
IB BOs that share a dma_resv (e.g. always-valid BOs, or two IBs backed
by the same BO). Every lock is now a top-level acquire under one
ww_acquire_ctx, so the recursive ww_mutex condition is gone, and the
per-IB amdgpu_bo_reserve()/amdgpu_bo_unref() dance -- including a BO
refcount leak on the amdgpu_bo_reserve() failure path -- is removed.

Subject: [PATCH 3971/5214] drm/amdkfd: Let driver decide buffer size at
 AMDKFD_IOC_GET_DMABUF_INFO ioctl

amdkfd driver needs allocate buffer to return bo metadata to user space. The
buffer size is controlled by user currently. It is a potential security issue
that hostile value (e.g. 2 GiB) lets any render-group user trigger order-MAX
allocation/OOM in kernel context.

This patch first finds bo metadata size. If the size is smaller than user
provided value drive can safely allocate buffer in kernel space and copy to
user space buffer. If not, driver will let user know, not allocate and copy.
User will redo with new buffer in user space.

This patch lets driver decide buffer allocation size to avoid potential hostile
size from user space.

Subject: [PATCH 3973/5214] drm/amdkfd: Use memdup_array_user to copy data
 from/to user space at kfd ioctls

Several kfd ioctls need transfer array data from/to user space. Kfd driver
uses kmalloc_array with user provided size. That can oversize alloc or 32-bit
wrap with hostile value. Replace it by memdup_array_user that does overflow
checking and allocates through dedicated slab caches, also physical continuous
as kmalloc.

Subject: [PATCH 3974/5214] drm/amdgpu: Fix context pstate override handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are several problems in the context pstate handling code.

The most serious ones are potential use-after-free and NULL pointer
dereferences at context initialization time. Both are due
amdgpu_ctx_init() not holding the adev->pm.stable_pstate_ctx_lock, which
is otherwise used from both sysfs and the context code itself for
modifying and clearing the stored context pointer.

Second issue is that context fini can trample over the pstate
configuration set via sysfs. This is due the restore state
(ctx->stable_pstate) being saved at context init time, and not if, or when
the context actually changes the pstate. As the context exits it will
therefore incorrectly restore to what was set before the sysfs override
was requested.

The simplest fix is to drastically simplify how the state is tracked, by
clearly defining the points at which pstate ownership is taken and
released, and to handle all transitions under the correct lock.

Instead of at context init time, the previous state is saved only at the
point the context overrides the current state, and is restored on context
exit only if the context is still the owner of the current override state.

Subject: [PATCH 3975/5214] selftests/ftrace: Drop invalid top-level local in
 test_ownership

test_ownership.tc is sourced by ftracetest under /bin/sh.

The script currently declares mount_point with local at file scope,
which makes /bin/sh abort with "local: not in a function" before the
test can reach the eventfs ownership checks.

Replace the top-level local declaration with a normal shell variable so
kernels that support the gid= tracefs mount option can run the test at
all.

Subject: [PATCH 3976/5214] drm/amdgpu: Respect placement requirements in
 amdgpu_gtt_mgr functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When testing intersection and compatibility, respect
the actual placement requirements. This is a pre-requisite
for ensuring that UVD CS BOs do not cross 256M segments.

Subject: [PATCH 3979/5214] drm/amdgpu/uvd: Fix forcing MSG, FB BOs into VCPU
 segment when it isn't at 0 (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

UVD 4.x and older can only access MSG, FEEDBACK buffers from a
specific 256M VRAM segment that the VCPU BO is also located in.
We already modify all placements of the given BO to ensure
the BO is placed within this segment.

Previously, it always assumed that the VCPU segment is
the first 256M of VRAM, even though under some conditions
the VCPU BO could be allocated outside this segment,
which made UVD non-functional as the BOs were
not inside the same segment as the UVD VCPU BO.

Solve that by using the segment where the VCPU BO actually is.

This fixes an issue with UVD failing to initialize on SI/CIK
when resizable BAR is enabled and the VCPU BO is allocated
in a different segment.

v2:
- For other BOs, keep using the same UVD segment as before.

Subject: [PATCH 3980/5214] drm/amdgpu/gfx9: Fix Ring and IB test fail after
 mode2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For Renior APU with gfx9, in some test scenarios with disabling
ring_reset, like accessing an unmapped invalid address, it can
trigger a gpu job timeout event, then driver uses Mode2 reset
to reset GPU, but after Mode2 compute Ring test and IB test fail
randomly. It because the HQDs of MECs are always active before or
after Mode2, that causes MECs use stale HQDs when MECs are unhalted
before driver restore MQDs, and causes CPC and CPF are still stuck
after Mode2, then causes compute Ring and IB tests fail.

So, add sequences to deactivate HQDs of MECs in suspend IP function
of the resetting process.

v2: Move all sequences into a new function gfx_v9_0_cp_mode2_clear_state (Ray Huang)
    To check reset Mode2 method in the if condition (Ray Huang)
v3: Move all sequences before Mode2 instead of after Mode2 (Timur Kristóf)
v4: Call amdgpu_gfx_rlc_enter/exit_safe_mode int the begin and end of
    gfx_v9_0_deactivate_kcq_hqd (Alex Deucher)

Subject: [PATCH 3981/5214] drm/amdkfd: Use exclusive bounds for SVM split
 alignment checks

SVM ranges use inclusive page indices: prange->last is the last page in
the range. The split-remap logic introduced by commit 448ee45353ef
("drm/amdkfd: Use huge page size to check split svm range alignment")
uses ALIGN_DOWN(prange->last, 512) to determine whether the original
range can contain a 2MB huge-page mapping.

That aligns the last page itself down. Thus a range ending one page
before the next 2MB boundary is classified as if the final 2MB block did
not exist. When such a range is split inside that final block, the
split head or tail can be left off the remap list even though it was
derived from an original range that may have PMD mappings.

Use prange->last + 1 as the exclusive upper bound when computing the
original range's last 2MB-aligned boundary. Then use the actual split
boundary for the head and tail alignment checks: tail->start for a tail
split, and new_start for a head split. new_start is equivalent to
head->last + 1 and directly names the exclusive end of the split head.

Using head->last for the head-side check can both remap a head that ends
exactly one page before a 2MB boundary and miss a head whose split
boundary is one page after such a boundary. Philip Yang pointed out in
the review of the original change that this condition should use
head->last + 1 or new_start.

Xiaogang Chen identified the inclusive-last cause and posted the
candidate fix in the regression thread. With the culprit change active
and the local revert not applied, the unchanged C/HSA reproducer
completes 10/10 runs with this change on an RX 7600 XT.

Subject: [PATCH 3983/5214] drm/amdgpu: Use system unbound workqueue for soft
 IH ring
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Allow the kernel to dispatch the soft IH work on other CPUs.

Otherwise it can happen that the soft IH ring fills up
before it actually starts processing anything, which
can easily happen with retry page faults, in which case
the CP repeatedly spams the CPU with a lot of interrupts.

This significantly improves retry page fault handling on
GPUs that don't have the filter CAM and must rely on
software based filtering.

Subject: [PATCH 3984/5214] selftests/uevent: increase __UEVENT_BUFFER_SIZE to
 avoid ENOBUFS on busy systems

The kselftests case uevent.uevent_filtering fails reproducibly on busy
systems (e.g.  Intel EMR / AMD servers) with:

  No buffer space available - Failed to receive uevent

The listener binds the NETLINK_KOBJECT_UEVENT socket to all 32 multicast
groups (nl_groups = -1) but only sets SO_RCVBUF to 4 KiB
(__UEVENT_BUFFER_SIZE = 2048 * 2).  On hosts with many devices, the kernel
and userspace daemons (udev/systemd) constantly emit uevents on multiple
groups, plus the test itself triggers 10 add events in a row.  The 4 KiB
receive buffer overflows before the listener can drain it, recvmsg()
returns -ENOBUFS, and the test bails out as failure.

Increase __UEVENT_BUFFER_SIZE to 1 MiB so the receive buffer is large
enough to absorb the burst of uevents on busy systems.  After this change
the test passes consistently across dozens of runs on Intel EMR and AMD
platforms.

Subject: [PATCH 3985/5214] fat: reject BPB volumes whose data area starts
 beyond total sectors

fat_fill_super() subtracts sbi->data_start from the BPB total sector count
before computing the number of clusters.  A malformed image can declare a
total sector count smaller than data_start, causing the subtraction to
underflow and the mount code to derive a plausible cluster count from the
FAT length instead.

Reject such images before the subtraction.  In QEMU, a crafted FAT image
with total_sectors=2 and data_start=3 mounted successfully before the fix
and reading a file returned bytes stored past the BPB-declared end of the
volume.  With this change, the same image is rejected during mount.

Subject: [PATCH 3986/5214] ocfs2: fix UBSAN array-index-out-of-bounds in
 ocfs2_sum_rightmost_rec

[BUG]
On-disk corruption setting l_next_free_rec to 0 in an inode's embedded
extent list triggers a UBSAN panic on the next write to that file.

[CAUSE]
ocfs2_sum_rightmost_rec() computes
i = le16_to_cpu(el->l_next_free_rec) - 1
and accesses el->l_recs[i] without validating i. When l_next_free_rec
is 0, i becomes -1; when l_next_free_rec exceeds l_count, i falls
past the end of the array. Either case violates the
__counted_by_le(l_count) annotation on l_recs[] and triggers UBSAN.

[FIX]
Validate the inode's embedded extent list when the inode is read, in
ocfs2_validate_inode_block(): l_count must be non-zero and no larger
than the inode block can hold, and l_next_free_rec must not exceed
l_count. A corrupt list is rejected at read time, before the b-tree
code can index l_recs[] out of bounds.

Of these, the misspelling of "assigned" is not yet flagged by checkpatch,
so also add it to scripts/spelling.txt.

The remaining matches of `grep -ri singed` are RISINGEDGE register and
enum names, not typos.

Subject: [PATCH 3988/5214] ocfs2: avoid moving extents to occupied clusters

For non-auto OCFS2_IOC_MOVE_EXT operations, userspace supplies a physical
me_goal.  ocfs2_move_extent() initializes new_phys_cpos from that goal and
expects ocfs2_probe_alloc_group() to replace it with a free run in the
target block group.

The probe currently leaves *phys_cpos unchanged if the scan reaches the
end of the group without finding a free run.  An occupied goal at the last
bit can therefore survive the probe and be passed to
__ocfs2_move_extent(), which copies file data into a cluster still owned
by another inode before the bitmap is updated.

When the probe does find a free run, it also subtracts move_len from the
ending bit.  The start of an N-bit run ending at i is i - N + 1, so the
current calculation can report the bit immediately before the free run.

Clear *phys_cpos before scanning and use the correct free-run start.
Callers already treat a zero result as -ENOSPC, so failed probes no longer
continue with an occupied caller-controlled goal.

Subject: [PATCH 3989/5214] lib: interval_tree_test: validate benchmark
 parameters

The interval tree runtime test accepts module parameters that are later
used as divisors while generating randomized intervals and while reporting
average timings.  For example, max_endpoint=1 makes the generated interval
end value zero and the next modulo operation divides by that zero value.

Reject non-positive counts and require max_endpoint to provide at least
one non-zero generated endpoint before the test allocates state or starts
the benchmark.

Subject: [PATCH 3990/5214] ocfs2: fix NULL h_transaction deref in
 ocfs2_assure_trans_credits

[BUG]
A direct write over unwritten extents can panic the kernel in
ocfs2_assure_trans_credits() when the journal aborts during DIO
completion. The crash is a general protection fault from a NULL pointer
dereference.

[CAUSE]
ocfs2_dio_end_io_write() loops over a direct write's unwritten extents,
marking each written under a single journal handle. If the journal
aborts (for example after an I/O error) while the extent tree is being
updated, the handle is left aborted with its transaction pointer
cleared. The extent merge treats that failure as not critical and
reports success, so the loop keeps using the handle.
ocfs2_assure_trans_credits() reads the handle's remaining credits
without first checking whether the handle is aborted, and that read
dereferences the cleared transaction pointer.

[FIX]
A journal abort is recorded in the handle itself, so callers are
expected to test the handle rather than rely on a returned error.
Make ocfs2_assure_trans_credits() do that, as the other ocfs2 journal
helpers already do, and return -EROFS when the handle is aborted.

Subject: [PATCH 3991/5214] ocfs2: fix circular locking dependency in
 ocfs2_dio_end_io_write

A circular locking dependency involves INODE_ALLOC_SYSTEM_INODE,
EXTENT_ALLOC_SYSTEM_INODE, and ORPHAN_DIR_SYSTEM_INODE.

1. ocfs2_mknod() acquires INODE_ALLOC then EXTENT_ALLOC.

2. ocfs2_dio_end_io_write() acquires EXTENT_ALLOC for unwritten
   extents, then ORPHAN_DIR via ocfs2_del_inode_from_orphan() while still
   holding EXTENT_ALLOC.

3. ocfs2_wipe_inode() acquires ORPHAN_DIR then INODE_ALLOC via
   ocfs2_remove_inode.

Break the cycle in ocfs2_dio_end_io_write() by freeing the allocation
contexts (releasing EXTENT_ALLOC) before acquiring ORPHAN_DIR.

Subject: [PATCH 3993/5214] net: ip_gre: require CAP_NET_ADMIN in the device
 netns for changelink

A tunnel changelink() operates on at most two netns, dev_net(dev) and
the tunnel link netns t->net. They differ once the device is created in
or moved to a netns other than the one the request runs in. The rtnl
changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a
caller privileged there but not in t->net can rewrite a tunnel that
lives in t->net.

Add rtnl_dev_link_net_capable() next to rtnl_get_net_ns_capable() in
net/core/rtnetlink.c. It requires CAP_NET_ADMIN in the link netns and is
skipped when the link netns is dev_net(dev), where the rtnl path already
checked it. The other patches in this series use the same helper.

Gate ipgre_changelink() and erspan_changelink() with it, at the top of
the op before any attribute is parsed, because the parsers update live
tunnel fields first. ipgre_netlink_parms() sets t->collect_md before
ip_tunnel_changelink() runs.

Commit 8b484efd5cb4 ("ip6: vti: Use ip6_tnl.net in
vti6_siocdevprivate().") added the same check on the ioctl path. This
adds it on RTM_NEWLINK.

Subject: [PATCH 3995/5214] net: ip_vti: require CAP_NET_ADMIN in the device
 netns for changelink

vti_changelink() operates on at most two netns, dev_net(dev) and the
tunnel link netns t->net. They differ once the device is created in or
moved to a netns other than the one the request runs in. The rtnl
changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a
caller privileged there but not in t->net can rewrite a tunnel that
lives in t->net.

Gate vti_changelink() on rtnl_dev_link_net_capable() at its top,
before any attribute is parsed.

Subject: [PATCH 4000/5214] net: ethernet: mtk_eth_soc: fix supported_interface
 set after phylink_create

Everything configured in phylink_config it's assumed to be set before
calling phylink_create() to permit correct parsing of all the different
modes and capabilities.

Commit 51cf06ddafc9 ("net: ethernet: mtk_eth_soc: add support for MT7988
internal 2.5G PHY") while introducing support for 2.5G phy for MT7988,
probably due to an auto-rebase, placed the configuration of the INTERNAL
interface mode for the supported_interfaces for phylink_config right after
phylink_create() introducing a possible problem with supported interfaces
parsing.

While this doesn't currently create any problem/bug, move setting this bit
before phylink_create() to prevent any possible regression in future code
change in phylink core.

Subject: [PATCH 4001/5214] netdev-genl: report NAPI thread PID in the caller's
 pid namespace

netdev_nl_napi_fill_one() reports the NAPI kthread PID in NETDEV_A_NAPI_PID
using task_pid_nr(), which returns the PID in the initial pid namespace.

NETDEV_CMD_NAPI_GET does not have GENL_ADMIN_PERM and the netdev genl family
is netnsok, so a caller in a child pid namespace can issue it. That caller
then sees the kthread's global PID, even though the kthread is not visible
in its pid namespace, where the value should be 0.

Translate the PID through the caller's pid namespace, the same way commit
3799c2570982 ("io_uring/fdinfo: translate SqThread PID through caller's
pid_ns") did for the io_uring SQPOLL thread. The doit and dumpit paths both
run synchronously in the caller's context, so task_active_pid_ns(current) is
the caller's pid namespace.

 page kernels

On ARM64 kernels with 64K pages, the trace_marker_raw test fails because
bash's printf builtin uses stdio buffering which splits output into
multiple small write() calls to the tracefs file. Since each individual
write is within TRACE_MARKER_MAX_SIZE (4096), they all succeed, causing
the "too big" write test to incorrectly pass.

Fix by writing through dd with iflag=fullblock to guarantee a single
atomic write() syscall to trace_marker_raw.

rvu_mbox_handler_npc_mcam_write_entry() call, so normal installs appeared
as errors in dmesg.  Use dev_dbg() for the success path and keep dev_err()
for real failures.

Subject: [PATCH 4005/5214] net: ehea: unwind probe_port sysfs file on failure

ehea_create_device_sysfs() creates probe_port and then remove_port. If
the second device_create_file() fails, the helper returns the error but
leaves probe_port installed even though probe treats the sysfs setup as
failed.

Remove probe_port on the remove_port creation failure path so the helper
leaves no partial sysfs state behind.

Subject: [PATCH 4006/5214] net: ipv4: bound TCP reordering sysctl writes and
 MTU probe sizes

Reject invalid `net.ipv4.tcp_reordering` values before they reach TCP
socket state. The sysctl is stored as an `int` but copied into the
`u32` `tp->reordering` field for new sockets, so negative writes wrap
to large values.

With `tcp_mtu_probing=2`, the wrapped value can overflow the
`tcp_mtu_probe()` size calculation and drive the MTU probing path into
an out-of-bounds read. Route `tcp_reordering` writes through
`proc_dointvec_minmax()` and require it to be at least 1. Also require
`tcp_max_reordering` to be at least 1 so the configured maximum cannot
become negative either.

When registering the table for a non-init network namespace, relocate
`extra2` pointers that refer into `init_net.ipv4` so the
`tcp_reordering` upper bound follows that namespace's
`tcp_max_reordering`.

Harden `tcp_mtu_probe()` itself by computing `size_needed` as `u64`.
This keeps the send queue and window checks from being bypassed through
signed integer overflow.

mlx5_query_mtppse() reads the Event Trigger Pin (MTPPSE) register but
reads the returned arm and mode values from the input buffer 'in'
instead of the output buffer 'out', so it always returns the values
that were written rather than the actual hardware state, making the
query useless.

The function has no in-tree callers. Remove it rather than fix it.

Subject: [PATCH 4009/5214] sctp: hold socket lock when dumping endpoints in
 sctp_diag

SCTP_DIAG endpoint dumping was traversing endpoint address lists without
holding lock_sock(), while those lists could change concurrently via
socket operations (e.g., bindx changes). This creates a race where
nla_reserve() counts addresses under RCU protection, but the subsequent
copy may see fewer entries, potentially leaking uninitialized memory to
userspace.

Fix this by:

- Taking a reference on each endpoint during hash traversal
- Moving socket operations (lock_sock()) outside read_lock_bh()
- Serializing address list access during dump
- Reworking sctp_for_each_endpoint() to support restart-based traversal
  with (net, pos) tracking

Also:

- Add WARN_ON_ONCE() for inconsistent address counts
- Fix idiag_states filtering for LISTEN vs association cases
- Skip dumping endpoints being freed (ep->base.dead)
- Move dump position tracking into iterator, removing cb->args[4] and
  its comment for sctp_ep_dump().,
- Update the comment for cb->args[4] and remove the comment for unused
  cb->args[5] for sctp_sock_dump().

Note: traversal is restart-based and may re-scan buckets multiple times,
but this is acceptable due to small bucket sizes and required to support
sleeping-safe callbacks.

This issue was reported by Nico Yip (@_cyeaa_) working with TrendAI Zero
Day Initiative.

Subject: [PATCH 4010/5214] gpio: sch: use raw_spinlock_t in the irq startup
 path

sch_irq_unmask() enables the GPIO IRQ and then updates the controller
state through sch_irq_mask_unmask(), which takes sch->lock with
spin_lock_irqsave().  The callback can be reached from irq_startup()
while setting up a requested IRQ.  That path is not sleepable, but on
PREEMPT_RT a regular spinlock_t becomes a sleeping lock.

This issue was found by our static analysis tool and then manually
reviewed against the current tree.

The grounded PoC kept the request_threaded_irq() -> __setup_irq() ->
irq_startup() -> sch_irq_unmask() -> sch_irq_mask_unmask() carrier and
used the original spin_lock_irqsave(&sch->lock) edge.  Lockdep reported:

  BUG: sleeping function called from invalid context
  hardirqs last disabled at ... __setup_irq.constprop.0 ... [vuln_msv]
  sch_rt_spin_lock_irqsave+0x1c/0x30 [vuln_msv]
  sch_irq_mask_unmask.constprop.0+0x31/0x70 [vuln_msv]
  __setup_irq.constprop.0+0xd/0x30 [vuln_msv]

Convert the SCH controller lock to raw_spinlock_t.  The same lock is
also used by the GPIO direction and value callbacks, but those critical
sections only update MMIO-backed GPIO registers and do not contain
sleepable operations.  Keeping this register lock non-sleeping is
therefore appropriate for the irqchip callbacks and does not change the
GPIO-side locking contract.

Subject: [PATCH 4012/5214] erofs: add folio order to trace_erofs_read_folio

erofs supports large folios for reads, but the actual folio order
instantiated in the page cache may be lower due to allocation
constraints such as memory fragmentation.

trace_erofs_read_folio already receives the folio being read but
currently records only its index. Add folio_order() to the tracepoint
so that users can observe the realized folio order and verify the
effectiveness of large folio reads.

Also drop the uptodate field: read_folio() is only called for a
non-uptodate folio, so it is always 0.

Subject: [PATCH 4013/5214] mm/slab: remove __GFP_NO_OBJ_EXT usage from
 alloc_slab_obj_exts()

__GFP_NO_OBJ_EXT has limited scope within the slab allocator itself and
gfp flags are a scarce resource, unlike slab's alloc_flags.

Introduce SLAB_ALLOC_NO_RECURSE alloc flag that has the same intent as
__GFP_NO_OBJ_EXT but a more generic name, meaning that a kmalloc()
family function should not recurse into another kmalloc*() for the
purposes of allocating auxiliary structures (obj_ext arrays or sheaves).

First, replace the __GFP_NO_OBJ_EXT for allocating obj_ext arrays in
alloc_slab_obj_exts(). Make use of the newly added kmalloc_flags()
function, where we can pass alloc_flags with SLAB_ALLOC_NO_RECURSE
added. This will also pass through SLAB_ALLOC_NOLOCK so we don't need
to special case kmalloc_nolock() anymore.

Note that until now the kmalloc_nolock() ignored the incoming gfp flags
and hardcoded __GFP_ZERO | __GFP_NO_OBJ_EXT. But it's correct to pass on
the incoming gfp flags (only augmented with __GFP_ZERO), because if
alloc_flags contain SLAB_ALLOC_NOLOCK, the incoming gfp flags have to
be also compatible with it. However, we might have added __GFP_THISNODE
for opportunistic slab allocation, as pointed out by Hao Li, and
__GFP_COMP by allocate_slab() as pointed out by Shengming Hu. Solve this
by adding both flags to OBJCGS_CLEAR_MASK as it makes sense to strip
them anyway for non-kmalloc_nolock() allocations of sheaves or obj_ext
arrays as well.

To avoid recursion of sheaf -> obj_ext -> sheaf -> ... allocations at
this patch, until the next patch converts sheaves to
SLAB_ALLOC_NO_RECURSE, use both gfp and alloc_flags for obj_ext. The
next patch will remove the gfp part.

Subject: [PATCH 4014/5214] mm/slab: replace __GFP_NO_OBJ_EXT with
 SLAB_ALLOC_NO_RECURSE for sheaves

Finish the switch away from __GFP_NO_OBJ_EXT by replacing it with
SLAB_ALLOC_NO_RECURSE when allocating empty sheaves. Pass alloc_flags to
[__]alloc_empty_sheaf(). Callers that can't be part of a recursive
kmalloc() chain simply pass SLAB_ALLOC_DEFAULT. Use kmalloc_flags()
instead of kzalloc() for allocating the sheaf.

With that we can finalize the removal the __GFP_NO_OBJ_EXT handling from
obj_ext allocations as well, leaving only SLAB_ALLOC_NO_RECURSE in
place.

This leaves __GFP_NO_OBJ_EXT with no users in slab, so stop allowing the
flag in kmalloc_nolock().

Subject: [PATCH 4020/5214] ALSA: caiaq: fix out-of-bounds read in the Traktor
 Kontrol S4 input parser

snd_usb_caiaq_tks4_dispatch() decodes the Traktor Kontrol S4 input
stream in fixed 16-byte (TKS4_MSGBLOCK_SIZE) message blocks. On every
iteration it advances buf and subtracts the block size while looping on
"while (len)".

len is urb->actual_length. That value is supplied by the device and is
not guaranteed to be a multiple of 16. When a final short block leaves
len between 1 and 15, the loop runs once more, reads up to buf[15], and
then does "len -= TKS4_MSGBLOCK_SIZE". As len is unsigned this underflows
to a huge value. The loop then keeps iterating and walking buf far past
the end of the 512-byte ep4_in_buf, reading out of bounds until a bogus
block id happens to be hit.

Iterate only while a full message block is available. This stops the
unsigned underflow and silently drops any trailing partial block, which
carries no complete control value anyway.

The sibling endpoint-4 parsers are not affected. The Traktor Kontrol X1
and Maschine arms in snd_usb_caiaq_ep4_reply_dispatch() floor
urb->actual_length before dispatching.

Subject: [PATCH 4021/5214] ALSA: caiaq: bound the length in the EP1 input
 parsers

snd_caiaq_input_read_erp() and snd_caiaq_input_read_io() can be reached
from snd_usb_caiaq_input_dispatch(). They read fixed byte offsets from
the reply buffer without checking the reported length. On a short reply
they decode stale bytes left from a previous, longer report and feed them
to the input layer.

This is not an out-of-bounds access. Every offset is a compile-time
driver constant. The largest is buf[21] in the Maschine ERP case. The
EP1 transfer buffer ep1_in_buf is EP1_BUFSIZE (64) bytes, and the USB
core caps actual_length at 64, so a short reply only reads in-bounds
stale data. Acting on data the device did not send is still wrong, so
bail out per usb_id case when the reply is shorter than the bytes that
case consumes.

  read_erp: AK1 needs 2 bytes, Kore needs 16, Maschine needs 22.
  read_io:  the Kore case needs 5 bytes (buf[4]) and the Traktor Kontrol
            X1 case needs 7 (buf[5]/buf[6]). The preceding key bit loop
            is already bounded by "i < len * 8" and is left untouched.

snd_caiaq_input_read_analog() and snd_usb_caiaq_maschine_dispatch() are
not changed. Their callers already floor the reply length.

Subject: [PATCH 4022/5214] ALSA: hda/realtek: Add headset mic quirk for Acer
 S40-54

Acer S40-54 with ALC256 does not restore headset mic detection properly
after S4 resume. After resume, headset plug events may no longer update
the headset mic state, leaving the headset microphone unavailable.

The system uses subsystem ID 1025:161f. Applying the existing
ALC256_FIXUP_ACER_MIC_NO_PRESENCE fixup restores headset mic detection
on this machine.

Add a machine-specific quirk for this system.

Subject: [PATCH 4023/5214] ALSA: usb-audio: qcom: reject stream disable with
 no active interface

handle_uaudio_stream_req() resolves an interface index with
info_idx_from_ifnum(), which returns -EINVAL when no interface matches.
The enable branch and the response: cleanup label both guard against a
negative index, but the disable branch does not: it forms
info = &uadev[pcm_card_num].info[info_idx] and dereferences it.

uadev[].info is a pointer allocated only when a stream is first enabled,
so a negative info_idx on the disable path is unsafe in two ways:

 - If the card was never enabled, .info is NULL and &info[-EINVAL] is a
   wild pointer; reading info->data_ep_pipe faults (kernel oops).

 - If the card was enabled at least once (.info allocated) and the
   disable names an interface that does not match, &info[-EINVAL] points
   before the allocation; info->data_ep_pipe / info->sync_ep_pipe are an
   out-of-bounds slab read and, when non-zero, an out-of-bounds 4-byte
   write (both pipe fields are cleared to 0). That is memory corruption,
   not just a NULL dereference.

The request is reachable from unprivileged local userspace over
AF_QIPCRTR. Reject a disable request with no resolved interface, matching
the guard the enable path already has.

On enable, subs->opened is set before the service_interval is validated;
an invalid interval jumps to the response label without clearing it, so
the substream is wedged at -EBUSY until a disable or disconnect.

Subject: [PATCH 4026/5214] ASoC: audio-graph-card2: Drop warning for manually
 selected DAI formats
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sometimes the DAI format must be specified in the audio-graph-card2
device tree, so emitting a warning can be misleading. Revert back to
emitting no warning.

A few examples where automatic format selection might not be applicable:

- For DPCM, where the other side of the DAI link is not apparent, no
  proper selection can actually be made. This can lead to disagreeing
  formats.

- Due to hardware peculiarities, some ostensibly supported formats might
  not work in practice.

In either case, the only correct solution is for the sound card to set
the format

Subject: [PATCH 4028/5214] PCI: iproc: Restore .map_irq() for the platform bus
 driver

Commit b64aa11eb2dd ("PCI: Set bridge map_irq and swizzle_irq to default
functions") moved the assignment of default .map_irq() callback to
devm_of_pci_bridge_init() and removed the initialization of
'iproc_pcie::map_irq' in platform bus driver.  This led to the callback
getting assigned the NULL pointer for platform bus driver, thereby breaking
the INTx functionality, since 'iproc_pcie::map_irq' overrides the
'pci_host_bridge::map_irq' callback in iproc_pcie_setup().

This issue only affected the iproc platform bus driver as this driver
relies on the default callback for non-PAXC controllers. iproc-brcm driver
was already providing the custom mapping function, so it was unaffected.

Restore the original (and intended) behaviour to use the default map_irq
function by removing the local 'iproc_pcie::map_irq' pointer and directly
assigning the 'pci_host_bridge::map_irq' callback in iproc-bcma driver.
This ensures that the default 'map_irq' callback is used for platform bus
driver and only iproc-brcm driver overrides it with a custom one.

Subject: [PATCH 4030/5214] ALSA: emu10k1: Use common error handling code in
 snd_emu10k1_playback_open()

Use an additional label so that a bit of exception handling can be better
reused at the end of this function implementation.

This issue was detected by using the Coccinelle software.

Subject: [PATCH 4039/5214] PCI: host-common: Request bus reassignment when not
 probe-only

pci_host_common_init() is used by several generic ECAM host drivers.
After PCI core changes around pci_flags and preserve_config, these hosts
no longer opted into full bus number reassignment the way they did
before, which broke enumeration of devices on a Marvell CN106XX board.

When PCI_PROBE_ONLY is not set, add PCI_REASSIGN_ALL_BUS so
pci_scan_bridge_extend() takes the reassignment path: bus numbers can be
assigned from firmware EA data (e.g. pci_ea_fixed_busnrs()). Skip the
flag in probe-only mode so existing assignments are not overridden.

Fixes: 7246a4520b4b ("PCI: Use preserve_config in place of pci_flags")

 reinitialization on resume

rpcif_spi_resume() currently passes the SPI controller device to
rpcif_hw_init(), but the function should be called with the RPC
interface device.

Retrieve the rpcif private data from the SPI controller and pass
rpc->dev instead. Also propagate the return value of rpcif_hw_init() so
that a failure during resume is properly reported rather than silently
ignored.

Subject: [PATCH 4041/5214] modpost: Ignore Clang LTO suffixes in symbol
 matching

When building the kernel with Clang ThinLTO enabled, the compiler
can mangle static variable names by appending suffixes such as
".llvm.<hash>" to prevent naming collisions across translation units.

This name mangling breaks the section mismatch whitelisting in modpost.
modpost relies on glob patterns (e.g., "*_ops" or "*_probe") to identify
safe references between permanent data and initialization code. Because
the LTO suffix modifies the end of the symbol name, legitimately
whitelisted structures fail the match, resulting in false positive
warnings.

For example, a static pernet_operations struct triggers the following:

  WARNING: modpost: vmlinux: section mismatch in reference: \

Subject: [PATCH 4042/5214] kconfig: add optional warnings for changed input
 values

When reading .config input, Kconfig stores user-provided values first
and then resolves the final value after applying dependencies, ranges,
and other constraints.

If the final value differs from the user input, Kconfig already tracks
that state internally, but it does not provide a focused diagnostic to
show which explicit inputs were adjusted. This is particularly confusing
for requested values that get forced down by unmet dependencies or
clamped by ranges.

Add an opt-in diagnostic controlled by KCONFIG_WARN_CHANGED_INPUT. Emit
the warnings from conf_write() and conf_write_defconfig() after value
resolution. Print the diagnostic to stderr directly, not through the
normal message callback, so it remains visible when conf is run with -s,
such as from make -s.

Keep the diagnostic out of the conf_message() formatting buffer so long
warning lists are not truncated, and mark processed symbols as written
before the SYMBOL_WRITE check so duplicate menu nodes cannot emit
duplicate warnings.

Document the new environment variable and add tests for olddefconfig,
savedefconfig, and the silent-conf path.

Remove the reference to the obsolete kselftest wiki.

The kselftest wiki is marked obsolete and is no longer updated. The last
edit was in 2019, and the information is outdated, referring readers for
support to IRC networks that have not been used for years, and to kernel

If there is any relevant information left in the wiki it needs to be
cleaned up and moved into the canonical kselftest documentation here.

Subject: [PATCH 4044/5214] smb: client: fix double-free in SMB2_flush() replay

SMB2_flush() keeps its response buffer bookkeeping across replay
attempts. If a replayable flush response is received and the retry then
fails before cifs_send_recv() stores a replacement response, flush_exit
will free the stale response pointer a second time.

Reinitialize resp_buftype and rsp_iov at the top of the replay loop so
cleanup only acts on response state produced by the current attempt.
This fixes a double-free without changing replay handling for successful
requests.

Subject: [PATCH 4047/5214] smb: client: fix double-free in SMB2_close() replay

A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_close_init() fails before the next send, cleanup
retains the previous buffer type and frees that response again.

Reset response bookkeeping before each attempt to prevent the stale free.

alpha-specific assembly implementation and __HAVE_ARCH_STRNCPY define,
falling back to the generic version in lib/string.c.

The __stxncpy helper (stxncpy.S/ev6-stxncpy.S) is retained as it is
still used by strncat.

Subject: [PATCH 4056/5214] string: Remove strncpy() from the kernel

strncpy() has been a persistent source of bugs due to its ambiguous
intended usage and frequently counter-intuitive semantics: it may not
NUL-terminate the destination, and it unconditionally zero-pads to the
full length, which isn't always needed. All former callers have been
migrated[1] to:

  - strscpy()        for NUL-terminated destinations
  - strscpy_pad()    for NUL-terminated destinations needing zero-padding
  - strtomem_pad()   for non-NUL-terminated fixed-width fields
  - memcpy_and_pad() for bounded copies with explicit padding
  - memcpy()         for known-length copies

Remove the generic implementation, its declaration, the FORTIFY_SOURCE
wrapper, and associated tests.

-strncpy() on NUL-terminated strings
------------------------------------
-Use of strncpy() does not guarantee that the destination buffer will
-be NUL terminated. This can lead to various linear read overflows and

-the destination buffer if the source contents are shorter than the

+---------
+strncpy() has been removed from the kernel. All former callers have
+been migrated to safer alternatives.
 
-When the destination is required to be NUL-terminated, the replacement is
-strscpy(), though care must be given to any cases where the return value
-of strncpy() was used, since strscpy() does not return a pointer to the
-destination, but rather a count of non-NUL bytes copied (or negative
-errno when it truncates). Any cases still needing NUL-padding should
-instead use strscpy_pad().
+strncpy() did not guarantee NUL-termination of the destination buffer,
+leading to linear read overflows and other misbehavior. It also
+unconditionally NUL-padded the destination, which was a needless
+performance penalty for callers using only NUL-terminated strings. Due
+to its various behaviors, it was an ambiguous API for determining what
+an author's true intent was for the copy.
 
-If a caller is using non-NUL-terminated strings, strtomem() should be
-used, and the destinations should be marked with the `__nonstring
-<https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html>`_
-attribute to avoid future compiler warnings. For cases still needing
-NUL-padding, strtomem_pad() can be used.
+The replacements for strncpy() are:
+
+- strscpy() when the destination must be NUL-terminated.
+- strscpy_pad() when the destination must be NUL-terminated and
+  zero-padded (e.g., structs crossing privilege boundaries).
+- memtostr() for NUL-terminated destinations from non-NUL-terminated
+  fixed-width sources (with the `__nonstring` attribute on the source).
+- memtostr_pad() for the same, but with zero-padding.
+- strtomem() for non-NUL-terminated fixed-width destinations, with
+  the `__nonstring` attribute on the destination.
+- strtomem_pad() for non-NUL-terminated destinations that also need
+  zero-padding.
+- memcpy_and_pad() for bounded copies from potentially unterminated
+  sources where the destination size is a runtime value.

Subject: [PATCH 4057/5214] net/sched: act_ct: preserve tc_skb_cb across
 defragmentation

tcf_ct_handle_fragments() calls nf_ct_handle_fragments() without saving
and restoring skb->cb. The defrag helper clears IPCB/IP6CB, which aliases
the tc_skb_cb/qdisc_skb_cb control buffer. Fragmented traffic through
act_ct therefore loses qdisc metadata such as pkt_segs and can trigger
WARN_ON_ONCE() in qdisc_pkt_segs() when panic_on_warn is enabled.

Save and restore the full tc_skb_cb around nf_ct_handle_fragments(),
matching the pattern used by ovs_ct_handle_fragments().

 cb preservation across defrag

Add a tc-testing case that sends IPv4 fragments through act_ct on clsact
egress while a root prio qdisc is present on the transmit path.

The test verifies that packet processing and qdisc accounting continue
to work after conntrack defragmentation, covering tc_skb_cb preservation
across defragmentation.

Subject: [PATCH 4059/5214] virtio-net: fix len check in receive_big()

receive_big() bounds the device-announced length by
(big_packets_num_skbfrags + 1) * PAGE_SIZE.  That is still too loose:
add_recvbuf_big() sets sg[1] to start at offset
sizeof(struct padded_vnet_hdr) into the first page, so the chain
actually carries hdr_len + (PAGE_SIZE - sizeof(padded_vnet_hdr)) +
big_packets_num_skbfrags * PAGE_SIZE bytes -- 20 bytes less than the
check allows for the common hdr_len == 12 case.

A malicious virtio backend can announce a len in that gap.  page_to_skb()
then walks one frag past the page chain, storing a NULL page->private
into skb_shinfo()->frags[MAX_SKB_FRAGS], which is both an out-of-bounds
write past the static frag array and a NULL frag handed up the rx path.

Bound len by the size add_recvbuf_big() actually advertised.

pch_gbe_alloc_tx_buffers() allocates an skb for each TX descriptor and
then passes the returned pointer to skb_reserve(). If netdev_alloc_skb()
fails, skb_reserve() dereferences NULL.

Make pch_gbe_alloc_tx_buffers() return an error when an skb allocation
fails. On failure, let pch_gbe_alloc_tx_buffers() clean the partially
allocated TX ring before returning the error. While bringing the device
up, release the RX buffer pool through a shared cleanup helper before
unwinding the IRQ setup.

Subject: [PATCH 4063/5214] octeontx2-af: cn10k: restrict VF LMTLINE sharing to
 its own PF

rvu_mbox_handler_lmtst_tbl_setup() uses req->base_pcifunc as a direct
index into the LMT map table to read another function's LMTLINE
physical base address and copy it into the caller's own LMT map table
entry. The mailbox dispatcher authenticates req->hdr.pcifunc from the
IRQ source, but req->base_pcifunc is a separate payload field and is
not sanitized.

Reject the request with -EPERM when a VF caller's base_pcifunc is not a
valid function under its own PF. is_pf_func_valid() bounds the FUNC field
to the PF's configured VF count, keeping the computed index inside the
caller's own slot block.

Subject: [PATCH 4065/5214] devlink: Fix parent ref leak on tc-bw failure

When a node is created via rate-new with tc-bw and a parent node,
devlink_nl_rate_set() executes the sequence of ops. It bails out on the
first failure and doesn't rollback anything. For most things that is
fine (setting some numbers), but the parent set can leak if there's
another failure after that.

That is precisely what happens when parent setting isn't the last block
in the function. After the referenced "Fixes" commit, when tc-bw fails
to be set the function bails out after having set the parent and
incremented its refcount.
There are two callers:
- devlink_nl_rate_set_doit() is fine, it just reports the error.
- but devlink_nl_rate_new_doit() frees the newly created node and leaks
  the parent refcnt.

Fix that by reordering the blocks so parent setting is last and adding a
comment explaining this so future modification preserve the ordering
(hopefully).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The MACB found in the Raspberry Pi RP1 suffers from sporadic stalls on
the TX queue.
While the exact root cause is not yet fully understood, it is likely
related to a hardware issue where a TSTART write to the NCR register
is missed, preventing the transmission from being kicked off.

Implement a timeout callback to handle TX queue stalls, triggering the
existing restart mechanism to recover.

Subject: [PATCH 4068/5214] flow_dissector: check device type before reading
 ETH_ADDRS

__skb_flow_dissect() unconditionally reads 12 bytes from eth_hdr(skb)
when FLOW_DISSECTOR_KEY_ETH_ADDRS is requested. This assumes the skb
has a valid Ethernet header at mac_header, which is not always the case.

The problem can be triggered by:
 1. Creating a TUN device in L3 mode (IFF_TUN, hard_header_len=0)
 2. Attaching a multiq qdisc with a flower filter matching on eth_src
 3. Sending a packet through AF_PACKET

Since TUN in L3 mode has no link-layer header, mac_header points to
the L3 data area. The flow dissector reads 12 bytes of uninitialized
skb memory, which then propagates through fl_set_masked_key() and is
used as a rhashtable lookup key in __fl_lookup(), as reported by KMSAN.

Rejecting the filter in the control path (at tc filter add time) is
not feasible because TC filter blocks can be shared between arbitrary
devices -- a filter installed on an Ethernet device may later classify
packets on a headerless device through a shared block. The device
association is not fixed at filter creation time.

Fix this by gating the memcpy on dev->type == ARPHRD_ETHER, which
ensures only true Ethernet-framed packets have their addresses read.
This is more precise than the previous hard_header_len >= 12 check,
which would incorrectly pass for non-Ethernet link types like IPoIB
(ARPHRD_INFINIBAND, hard_header_len=24) and FDDI (hard_header_len=21)
whose L2 headers are not in Ethernet format. Additionally check
skb_mac_header_was_set() to guard against the pathological case where
mac_header is the unset sentinel (~0U), which would cause eth_hdr() to
return a wild pointer.

For the act_mirred redirect case (Ethernet packet redirected to a
non-Ethernet device sharing a TC block), zeroing the key is the correct
behavior: the packet is now being classified on the target device, where
Ethernet address matching is not semantically meaningful.

Note: on non-Ethernet devices, the zeroed key will match a filter
configured with all-zero MAC addresses. This is an improvement over the
previous behavior where uninitialized memory could randomly match any
filter.

Subject: [PATCH 4069/5214] netconsole: don't drop the last byte of a
 full-sized message

nt->buf is exactly MAX_PRINT_CHUNK bytes, but scnprintf() reserves one
byte for its NUL terminator, so a non-fragmented payload of exactly
MAX_PRINT_CHUNK loses its last byte (emitted as a stray NUL in the
release path). Grow nt->buf to MAX_PRINT_CHUNK + 1 and bound the
scnprintf() calls with sizeof(nt->buf); the transmitted length stays
capped at MAX_PRINT_CHUNK.

Alternatively, nt->buf could be left at MAX_PRINT_CHUNK and the NUL byte
reserved by routing exactly-MAX_PRINT_CHUNK payloads to fragmentation
('len < MAX_PRINT_CHUNK'), at the cost of fragmenting those messages.
But it would look less sane, thus the current approach.

Subject: [PATCH 4070/5214] net: thunderbolt: Fix frags[] overflow by bounding
 frame_count

tbnet_poll() assembles a multi-frame ThunderboltIP packet into one skb. The
first frame goes into the skb linear area and every further frame is added as
a page fragment.

	skb_add_rx_frag(skb, skb_shinfo(skb)->nr_frags,
			page, hdr_size, frame_size,
			TBNET_RX_PAGE_SIZE - hdr_size);

A packet of frame_count frames therefore ends up with frame_count - 1
fragments. tbnet_check_frame() only bounds the peer supplied frame_count to
TBNET_RING_SIZE / 4 (64), which is far above MAX_SKB_FRAGS (17 by default). A
peer that sends a packet of 19 or more small frames pushes nr_frags past
MAX_SKB_FRAGS, so skb_add_rx_frag() writes past skb_shinfo()->frags[] and
corrupts memory after the shared info.

Tighten the start of packet bound to MAX_SKB_FRAGS + 1 so a packet can never
produce more fragments than frags[] can hold. This matches the recent skb
frags overflow fixes in other receive paths, for example f0813bcd2d9d ("net:
wwan: t7xx: fix potential skb->frags overflow in RX path") and 600dc40554dc
("net: usb: cdc-phonet: fix skb frags[] overflow in rx_complete()").

Subject: [PATCH 4071/5214] gve: fix header buffer corruption with header-split
 and HW-GRO

The DQO RX datapath programs a per-buffer-queue-descriptor
header_buf_addr at post time and reads the split header back at
completion time. Both the post and the read currently index the
header buffer by queue position rather than by the buffer's identity:

  - post (gve_rx_post_buffers_dqo): header_buf_addr is computed from
    bufq->tail
  - read (gve_rx_dqo): the header is read from desc_idx (the completion
    queue head index)

This relies on the buffer-queue index and the completion-queue index
being equal for the start of every packet, i.e. on the device consuming
posted buffers and returning completions in the exact same order. That
assumption does not hold once HW-GRO is enabled with multiple
flows: coalesced segments are accepted and completed in an order that
may differ from the order buffers were posted, and segments from
different flows may interleave.

That results in two problems:

1. Wrong header slot on read. Because the read offset is derived from
   the completion index (desc_idx) while the device wrote the header to
   the address programmed for the buffer's buf_id, the driver can copy
   a header belonging to a different packet. This shows up as
   throughput drop (about 30% drop and large numbers of TCP
   retransmissions) with header-split and HW-GRO both enabled and many
   streams.

2. Header buffer reused while still owned by the device. The driver
   advances bufq->head by one per completion and re-posts buffers based
   on that. Arrival of N RX completions only guarantees that at least N
   RX buffer descriptors have been read by the device. It does not
   guarantee that the device has relinquished the ownership of all the
   buffers corresponding to those N descriptors. With out-of-order
   completions (e.g. the completion for a packet copied into buffer N
   arrives before the completion for a packet copied into buffer N-1),
   the driver can re-post and overwrite a header buffer that the device
   is still going to write into, corrupting the header of a packet
   whose completion has not yet been processed.

Fix both issues by indexing the header buffer by buf_id on both the post
and read paths. Reading from buf_id's slot is therefore always correct
regardless of completion ordering (fixes problem 1).

Indexing by buf_id also ties each header slot to the lifetime of its
buffer state. A buffer state is only returned to the free/recycle lists
when its own completion (buf_id) is processed, so its header slot can
only be re-posted after the device is done with it. This makes header
slot reuse safe under out-of-order completions (fixes problem 2).

Allocate (gve_rx_alloc_hdr_bufs) and free (gve_rx_free_hdr_bufs) the
header buffers based on num_buf_states to match the buf_id indexing.

Subject: [PATCH 4072/5214] net: ena: clean up XDP TX queues when regular TX
 setup fails

create_queues_with_size_backoff() creates XDP TX queues before setting
up the regular TX path. If the subsequent allocation or creation of
regular TX queues fails, the error handling paths omit the teardown of the
XDP TX queues, leading to a resource leak.

Fix this by explicitly destroying the XDP TX queue subset at the two
missing failure points.

The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1-rc7.

An x86_64 allyesconfig build showed no new warnings. As we do not have
an ENA device to test with, no runtime testing was able to be performed.

Subject: [PATCH 4074/5214] net: wangxun: don't advertise IFF_SUPP_NOFCS

Like commit a24162f18825("i40e: don't advertise IFF_SUPP_NOFCS"),
ngbe and txgbe also advertises IFF_SUPP_NOFCS and allowing users
to use the SO_NOFCS socket option. But the driver does not check
skb->no_fcs, so this option is silently ignored.

With this change, send() fails with -EPROTONOSUPPORT when AF_PACKET
socket is set SO_NOFCS option.

Subject: [PATCH 4076/5214] net: rds: check cmsg_len before reading
 rds_rdma_args in size pass

rds_rm_size() handles RDS_CMSG_RDMA_ARGS after only CMSG_OK() and then
calls rds_rdma_extra_size(), which reads args->local_vec_addr and
args->nr_local without first checking that cmsg_len covers struct
rds_rdma_args. The other two RDS_CMSG_RDMA_ARGS consumers already guard
this: rds_rdma_bytes() in rds_sendmsg() and rds_cmsg_rdma_args() in
rds_cmsg_send() both reject cmsg_len < CMSG_LEN(sizeof(struct
rds_rdma_args)). Add the same check to rds_rm_size() so all three RDMA
args passes are consistent.

This is a consistency and hardening change with no behavioral effect for
well-formed senders and no reachable bug today: rds_rdma_bytes() runs
before rds_rm_size() in rds_sendmsg() and already rejects a short
RDS_CMSG_RDMA_ARGS, so the size pass is not reached with an undersized
cmsg. But rds_rm_size() reads the args independently of that earlier
pass, and nothing in rds_rm_size() itself records or enforces the
precondition, so a reader or a future refactor of the size pass cannot
tell the cmsg has already been length-checked. Applying the same
cmsg_len guard in all three RDS_CMSG_RDMA_ARGS consumers keeps that
invariant local to each and robust to reordering.

Subject: [PATCH 4077/5214] tipc: fix slab-use-after-free Read in
 tipc_aead_decrypt_done

tipc_aead_decrypt() goes straight from tipc_bearer_hold(b) to
crypto_aead_decrypt(req) without taking a reference on the netns, unlike
the encrypt path. When crypto_aead_decrypt() is offloaded asynchronously
(e.g. the SIMD aead wrapper queuing to cryptd), the cryptd worker runs
tipc_aead_decrypt_done() later. If the bearer's netns is torn down in the
meantime, cleanup_net() -> tipc_exit_net() -> tipc_crypto_stop() frees the
per-netns tipc_crypto, and the completion then reads it:
tipc_aead_decrypt_done() dereferences aead->crypto->stats and
aead->crypto->net, and tipc_crypto_rcv_complete() dereferences
aead->crypto->aead[] and the node table -- reading freed memory.

Decoded KASAN splat (v7.1-rc7, CONFIG_KASAN_INLINE + TIPC + TIPC_CRYPTO):

   kthread (kernel/kthread.c:436)

This is the same class of bug that commit e279024617134 ("net/tipc: fix
slab-use-after-free Read in tipc_aead_encrypt_done") fixed for the encrypt
side. The encrypt path takes maybe_get_net(aead->crypto->net) before
crypto_aead_encrypt() and drops it with put_net() on the synchronous
return paths and in tipc_aead_encrypt_done(); the -EINPROGRESS/-EBUSY
return keeps the reference for the async callback to release. The decrypt
path was left without the equivalent guard.

Mirror the encrypt-side fix on the decrypt path: take a net reference
before crypto_aead_decrypt() (failing with -ENODEV and the matching
bearer put if it cannot be acquired), keep it across the
-EINPROGRESS/-EBUSY async return, and drop it with put_net() on the
synchronous success/error return and at the end of
tipc_aead_decrypt_done().

Reproduced under KASAN on v7.1-rc7: a UDP bearer with a cluster key is
flooded with crafted encrypted frames from an unknown peer (driving the
cluster-key decrypt path) while the bearer's netns is repeatedly torn
down. The completion must run asynchronously to outlive
tipc_crypto_stop(); on x86 the stock aesni gcm(aes) now decrypts
synchronously, so the async path was exercised via cryptd offload. The
unguarded aead->crypto dereference in tipc_aead_decrypt_done() is the
unpatched upstream path; tipc_aead_decrypt() still lacks
maybe_get_net(aead->crypto->net), so the completion can outlive the free
on any config where crypto_aead_decrypt() goes async.

Found by 0sec automated security-research tooling (https://0sec.ai).

Subject: [PATCH 4080/5214] rust: Kbuild: set frame-pointer llvm module flag
 for CONFIG_FRAME_POINTER

Due to a rustc bug, the -Cforce-frame-pointers=y flag only emits the
frame-pointer annotation for functions, but not for the module. This
means that functions generated by the LLVM backend such as
'asan.module_ctor' do not receive the frame-pointer annotation.

This is likely to lead to broken backtraces and may also cause issues
with ftrace if these features are used with functions generated by the
LLVM backend.

Thus, use -Zllvm_module_flag to work around this rustc bug if using a
rustc without the fix.

  2026-08-20). - Miguel ]

Subject: [PATCH 4081/5214] ALSA: usb-audio: Kill MIDI 2.0 URBs before freeing
 endpoints

MIDI 2.0 input URBs are started during snd_usb_midi_v2_create(). A
later setup failure can still jump to snd_usb_midi_v2_free(), which
currently frees each endpoint and its coherent URB buffers without first
stopping the submitted URBs. A completion can then dereference the
embedded URB context and endpoint state after they have been freed, or
try to resubmit from the stale endpoint.

This was observed as a KASAN slab-use-after-free in
input_urb_complete().

The buggy scenario involves two paths, with each column showing the order
within that path:

probe error path:                         USB completion path:
1. start_input_streams() submits          1. The HCD still owns a
   input URBs.                               submitted input URB.
2. A later setup helper returns           2. input_urb_complete() runs
   an error.                                 with urb->context in ep.
3. snd_usb_midi_v2_free() frees           3. The completion reads ep
   endpoint storage and URB buffers.         state and can requeue URBs.

Make the endpoint destructor follow the same teardown ordering used for
disconnect when the endpoint has not already been disconnected: publish
ep->disconnected, kill the URBs synchronously, and drain the endpoint
before freeing URB buffers and endpoint storage. The guard avoids
repeating the stop sequence after the normal
snd_usb_midi_v2_disconnect_all() path, while still synchronizing the
direct MIDI 2.0 create-error free path.

Subject: [PATCH 4082/5214] ALSA: hda/realtek: Enable mute LED on HP EliteBook
 840 G6

The HP EliteBook 840 G6 (PCI SSID 103c:854d) has an ALC215 codec whose
mic-mute and audio-mute LEDs are wired to the same GPIOs as the already
supported EliteBook 830 G6 and 840 G7. Without a matching quirk the LEDs
are never registered, so the front-panel mic-mute LED stays permanently
lit and does not track the mute state.

Apply ALC285_FIXUP_HP_GPIO_LED, mirroring the sibling EliteBook entries.
With this fixup the codec registers an "hda::micmute" LED class device and
the LED correctly follows the capture-mute state. This was verified on the
affected machine by forcing the same fixup at runtime via
snd_sof_intel_hda_generic.hda_model=103c:8548, which made the LED work as
expected.

Subject: [PATCH 4083/5214] x86/platform/geode: reference the real node of the
 cs5535 GPIO controller

GPIO software node lookup should rely exclusively on matching the
addresses of the referenced firmware nodes. Commit e5d527be7e69 ("gpio:
swnode: don't use the swnode's name as the key for GPIO lookup") tried to
enforce this but had to be reverted: it broke existing users who abuse the
software node mechanism by creating "dummy" software nodes named after the
device they want to get GPIOs from, without ever attaching them to the
actual GPIO devices. Those users rely on GPIOLIB matching the label of the
GPIO controller against the name of the software node rather than on a real
firmware node link.

Un-reverting e5d527be7e69 therefore requires converting all such users to
real firmware node lookup. The geode board setup is one of them: it
references the cs5535 GPIO controller through a locally-defined dummy node
named "cs5535-gpio".

The cs5535 MFD driver now exports the software node associated with its
GPIO controller cell as cs5535_gpio_swnode. Use it as the target of the
GPIO software node references in geode-common.c instead of the dummy node,
so the lookup resolves by firmware node address. As the referenced node
must exist at lookup time, make the cs5535 driver built-in for all boards
selecting GEODE_COMMON (depend on GPIO_CS5535=y). The node is exported in
the "CS5535" namespace, so import it in this module.

Subject: [PATCH 4084/5214] netfilter: flowtable: fix offloaded ct timeout
 never being extended

OpenWrt has recently migrated many platforms to kernel 6.18. On the
MediaTek platform, which supports hardware network offloading, WiFi
connections accelerated via the WED path were observed to drop after
roughly 300 seconds.

After several debugging sessions, assisted by the Claude LLM, the
problem was narrowed down as follows:

nf_flow_table_extend_ct_timeout() extends ct->timeout for offloaded
flows using:

	cmpxchg(&ct->timeout, expires, new_timeout);

'expires' comes from nf_ct_expires(ct) and is a relative value, while
ct->timeout holds an absolute timestamp. The two are never equal, so
the cmpxchg always fails and the timeout is never extended.

This goes unnoticed for most flows, but a long-lived hardware (WED)
offloaded flow on MediaTek MT7986 eventually has ct->timeout decay to
zero, the conntrack entry is reaped and the connection breaks.

Open-code the relative value from a single READ_ONCE(ct->timeout)
snapshot and compare against that same absolute snapshot in the
cmpxchg, so the timeout extension actually takes effect while the
datapath remains authoritative if it updates ct->timeout concurrently.

Subject: [PATCH 4086/5214] netfilter: nf_queue: pin bridge device while
 NFQUEUE holds fake dst

The br_netfilter fake rtable is embedded in struct net_bridge and is
attached to bridged packets with skb_dst_set_noref(). If such a packet is
queued to NFQUEUE, __nf_queue() upgrades that fake dst with
skb_dst_force().

At that point the queued skb can hold a real dst reference after bridge
teardown has started. The problem is not that every bridged packet needs
its own dst reference. The problem is that NFQUEUE can keep the bridge
private fake dst alive after unregister begins.

Fix this by keeping the bridge fake dst model unchanged and pinning the
bridge master device only while the packet sits in NFQUEUE. Record the
bridge device in nf_queue_entry when the queued skb carries a bridge fake
dst, take a device reference for the queue lifetime, and drop it when the
queue entry is freed.

Also make sure queued entries are reaped when that bridge device goes
down, and drop the redundant nf_bridge_info_exists() test from the fake
dst detection.

This keeps netdev_priv(br->dev) alive until verdict completion, so the
embedded fake rtable and its metrics backing storage cannot be freed out
from under dst_release(). It also avoids the constant refcount bump and
avoids using ipv4-specific dst helpers for IPv6 bridge traffic.

Subject: [PATCH 4087/5214] netfilter: xt_cluster: reject template conntracks
 in hash match

xt_cluster_mt() treats any non-NULL nf_ct_get() result as a fully
initialized conntrack and passes it to xt_cluster_hash().

This causes a state confusion bug when the raw table CT target attaches
a template conntrack to skb->_nfct before normal conntrack processing.
Templates carry IPS_TEMPLATE status but do not have a valid tuple for
hashing yet, so xt_cluster_hash() can hit its WARN_ON() path on the
zeroed l3num field.

Reject template conntracks before hashing them. This matches existing
netfilter handling for template objects and avoids hashing incomplete
conntrack state.

Subject: [PATCH 4088/5214] netfilter: flowtable: fix and simplify IP6IP6
 tunnel handling

Fix nf_flow_ip6_tunnel_proto() to use pskb_may_pull() instead of
skb_header_pointer() to ensure the outer IPv6 header is in the skb
headroom, which is required for subsequent packet processing. Move
ctx->offset update inside the IPPROTO_IPV6 conditional block since it
should only be adjusted when an IP6IP6 tunnel is actually detected.
Simplify the rx path by removing ipv6_skip_exthdr() and checking
ip6h->nexthdr directly, as the flowtable fast path only handles simple
IP6IP6 encapsulation without extension headers.
Drop the tunnel encapsulation limit destination option support from the
tx path to match, since the rx path no longer handles extension headers.
Remove the encap_limit parameter from nf_flow_offload_ipv6_forward(),
nf_flow_tunnel_ip6ip6_push() and nf_flow_tunnel_v6_push(), along with
the ipv6_tel_txoption struct and related headroom/MTU adjustments.

WCR.BAS=0xfe and the hardware watches bytes [1..7] instead of the
requested [1..8] -- the eighth byte is silently dropped.  The
syscall still returns success, leaving userspace to discover the
gap by empirical probing.

The same class affects HW_BREAKPOINT_LEN_{2,4} when offset pushes the
high BAS bit past bit 7 (e.g. LEN_4 with offset=5 yields 0xe0
instead of 0x1e0).  No memory-safety impact -- the value is masked
into 8 bits before encoding -- but debuggers and perf users observe
missed events on bytes they thought they were watching.

The AArch32 branch immediately above already rejects unrepresentable
(offset, len) combinations via an explicit switch.  Mirror that for
the non-compat branch by checking that the shifted pattern fits in
the BAS field, returning -EINVAL when it does not.

GDB and similar debuggers are unaffected by the stricter check.
aarch64_linux_set_debug_regs() already treats EINVAL on
NT_ARM_HW_WATCH as a downgrade signal: it clears
kernel_supports_any_contiguous_range, calls aarch64_downgrade_regs()
to round the BAS up to a legacy 0x01/03/0f/ff mask with an aligned
base, and retries -- the same fallback path that PR-20207 introduced.
The new -EINVAL is therefore reachable only from a raw
perf_event_open() that pairs an unaligned base with an oversized
bp_len, which is precisely the bug.

Reproducer:

  struct perf_event_attr a = {
      .type = PERF_TYPE_BREAKPOINT, .size = sizeof(a),
      .bp_type = HW_BREAKPOINT_W,
      .bp_addr = (uintptr_t)(buf + 1),
      .bp_len = HW_BREAKPOINT_LEN_8,
      .exclude_kernel = 1, .exclude_hv = 1,
  };
  int fd = perf_event_open(&a, 0, -1, -1, 0);
  /* before this fix: succeeds, watches 7 bytes (buf+1..buf+7)   */
  /* after  this fix: fails with EINVAL                          */

Subject: [PATCH 4096/5214] thermal: intel: Fix dangling resources on
 thermal_throttle_online() failure

The function thermal_throttle_add_dev() may fail and abort a CPU hotplug
online operation. Since the failure occurs within the online callback,
thermal_throttle_online(), the CPU hotplug framework does not invoke the
corresponding offline callback. As a result, the hardware and software
resources set up during the failed operation are not torn down.

Since only thermal_throttle_add_dev() can fail, call it before setting up
the rest of the resources.

Subject: [PATCH 4099/5214] ACPI: IPMI: Fix inverted interface check in
 ipmi_bmc_gone()

Before commit a1a69b297e47 ("ACPI / IPMI: Fix race caused by the
unprotected ACPI IPMI user"), ipmi_bmc_gone() skipped entries whose
interface number did not match the SMI being removed, then killed the
matching entry:

	if (ipmi_device->ipmi_ifnum != iface)
		continue;

	__ipmi_dev_kill(ipmi_device);

That commit folded the removal block into the existing non-match test
while converting the object lifetime handling, but left the comparison
unchanged. The old != meant "continue past this entry"; after the
refactor it meant "kill this entry".

As a result, a single ACPI IPMI interface is never removed when its SMI
disappears. If multiple interfaces are tracked, the first interface
whose number differs from iface is removed instead, while the interface
that actually disappeared remains on driver_data.ipmi_devices. The
stale entry is not marked dead and can continue to be selected for ACPI
IPMI transactions. It can also prevent the same ACPI handle from being
registered again.

Change the comparison to == so ipmi_bmc_gone() removes exactly the
interface reported as gone by the SMI watcher. This restores the
pre-a1a69b297e47 behavior and is the correct interface matching logic.

Subject: [PATCH 4101/5214] ieee802154: Avoid calling WARN_ON() on -ENOMEM in
 cfg802154_switch_netns()

It's pointless to call WARN_ON() in case of an allocation failure in
dev_change_net_namespace() and device_rename(), since it only leads to
useless splats caused by deliberate fault injections, so avoid it.

Subject: [PATCH 4103/5214] sched/mmcid: Fix OOB clear_bit when CID is
 MM_CID_UNSET in fixup path

In mm_cid_fixup_cpus_to_tasks(), when rq->curr has the target mm and
mm_cid.active is set, the CID is checked with cid_in_transit() before
setting the transition bit.  In per-CPU mode a newly forked or exec'd
task can be running with mm_cid.cid == MM_CID_UNSET because CIDs are
assigned lazily on schedule-in.  With cid_in_transit() the guard passes
for MM_CID_UNSET (no transit bit), converts it to MM_CID_UNSET |
MM_CID_TRANSIT and stores it back; later mm_cid_schedout() feeds this
to clear_bit() with MM_CID_UNSET as the bit number, triggering an
out-of-bounds write.

Symptoms: this is genuine memory corruption, but a bounded out-of-bounds
write, not an arbitrary one.  MM_CID_UNSET is the fixed sentinel BIT(31),
so once the bad value reaches mm_cid_schedout() the cid_from_transit_cid()
strip leaves MM_CID_UNSET, which fails the "cid < max_cids" convergence
test and falls into mm_drop_cid() -> clear_bit(MM_CID_UNSET,
mm_cidmask(mm)).  The cid bitmap is embedded in the mm_struct slab object
(after cpu_bitmap and mm_cpus_allowed) and is only num_possible_cpus()
bits wide, so clearing bit 31 is a deterministic OOB bit-clear at a
fixed offset of 2^31 / 8 == 256 MiB past the bitmap base.  The address is
not attacker-influenced (fixed sentinel -> fixed offset) and the op only
clears a single bit; what sits 256 MiB further along the direct map is
whatever kernel object happens to live there, so this corrupts one bit of
unpredictable kernel memory -- it is not an arbitrary-address or
arbitrary-value write.

It triggers only in per-CPU CID mode, when a CPU is running an active
task of the target mm whose cid is still MM_CID_UNSET -- the
fork()/execve() window before that task's next schedule-in assigns it a
real CID -- and a per-CPU -> per-task fixup walks over it (the mode
fallback driven by a thread exit, sched_mm_cid_exit(), or by the deferred
max_cids recompute in mm_cid_work_fn()).

In practice syzkaller surfaced it as a KASAN use-after-free reported in
__schedule -> mm_cid_switch_to, where the offending clear_bit() is inlined
via mm_cid_schedout() -> mm_drop_cid().

Guard the transition-bit assignment against MM_CID_UNSET, in addition to
the existing cid_in_transit() check, so the bit is only set on a genuine
task-owned CID.  A CPU-owned (MM_CID_ONCPU) CID of a running active task
is handled by the cid_on_cpu(pcp->cid) branch above and never reaches
this path, so excluding MM_CID_UNSET (and the already-transitioning case)
is sufficient.

Subject: [PATCH 4104/5214] ieee802154: ca8210: fix cas_ctl leak on spi_async
 failure

ca8210_spi_transfer() allocates cas_ctl with kzalloc_obj(GFP_ATOMIC)
and relies entirely on the SPI completion callback
ca8210_spi_transfer_complete() to free it.

The spi_async() API only invokes the completion callback on successful
submission.  On failure it returns a negative error code without ever
queuing the callback, which leaves cas_ctl and its embedded spi_message
and spi_transfer orphaned.  Every kfree(cas_ctl) in the driver is
inside the completion callback, so there is no other reclamation path.

ca8210_spi_transfer() is called from ca8210_spi_exchange(), the
interrupt handler ca8210_interrupt_handler(), and from the retry path
inside the completion callback itself.  The exchange and interrupt
handler paths loop on -EBUSY, so under sustained SPI bus contention
every retry iteration leaks a fresh cas_ctl (~600 bytes per
occurrence).

Fix it by freeing cas_ctl on the spi_async() error path.  While here,
correct the misleading error string: the function calls spi_async(),
not spi_sync().

Subject: [PATCH 4105/5214] ieee802154: ca8210: fix pointer truncation in kfifo
 on 64-bit

ca8210_test_int_driver_write() and ca8210_test_int_user_read() exchange
a kmalloc'd buffer pointer through a struct kfifo, but pass a literal
'4' as the byte count to kfifo_in()/kfifo_out().

This is correct on 32-bit (pointer = 4 bytes), but on 64-bit only the
low 4 bytes of the 8-byte pointer are written into the FIFO. The reader
then reads back 4 bytes into an 8-byte local pointer variable, leaving
the upper 4 bytes uninitialized stack data. The first dereference of
the reconstructed pointer (fifo_buffer[1]) accesses an arbitrary kernel
address and generally results in an oops.

Use sizeof(fifo_buffer) so the byte count matches pointer width on every
architecture.

The driver has no architecture restriction in Kconfig, so any 64-bit
build with CONFIG_IEEE802154_CA8210_DEBUGFS=y is exposed. Issue has
been latent since the driver was added in 2017 because it is most
commonly deployed on 32-bit MCUs.

Found via a custom Coccinelle semantic patch hunting for short-byte
kfifo I/O on byte-mode kfifos used to shuttle pointers.

Subject: [PATCH 4106/5214] mac802154: llsec: add skb_cow_data() before
 in-place crypto

llsec_do_encrypt_unauth(), llsec_do_encrypt_auth(),
llsec_do_decrypt_unauth(), and llsec_do_decrypt_auth() all perform
in-place cryptographic transformations on skb data.  They build a
scatterlist with sg_init_one() pointing into the skb's linear data area
and then pass the same scatterlist as both src and dst to the crypto API
(e.g. crypto_skcipher_encrypt/decrypt, crypto_aead_encrypt/decrypt).

On the RX path, __ieee802154_rx_handle_packet() clones the received skb
before handing it to each subscriber via ieee802154_subif_frame().  The
cloned skb shares the same underlying data buffer via reference
counting.  When llsec_do_decrypt() subsequently modifies this shared
buffer in place, it corrupts data that other clones -- potentially
belonging to other sockets or subsystems -- still reference.

On the TX path, similar data sharing can occur when an skb's head has
been cloned (skb_cloned() returns true).

The fix is to call skb_cow_data() before performing any in-place crypto
operation.  skb_cow_data() ensures that the skb's data area is not
shared: if the skb head is cloned or the data spans multiple fragments,
it copies the data into a private buffer that can be safely modified in
place.  This is the same pattern used by:

  - ESP (net/ipv4/esp4.c, net/ipv6/esp6.c)
  - MACsec (drivers/net/macsec.c)
  - WireGuard (drivers/net/wireguard/receive.c)
  - TIPC (net/tipc/crypto.c)

Without this guard, in-place crypto on shared skb data leads to:
  - Silent data corruption of other skb clones
  - Use-after-free when the crypto API scatterwalk writes through a
    page that has already been freed by another clone's kfree_skb()
  - Kernel crashes under concurrent 802.15.4 traffic with security
    enabled (KASAN/KMSAN reports slab-use-after-free)

Found by 0sec (https://0sec.ai) using automated source analysis.

The issue occurs because the `pan_id` field of `struct ieee802154_addr`
is left uninitialized when the address mode is `IEEE802154_ADDR_NONE`.
The execution flow is as follows:

1. `__ieee802154_rx_handle_packet()` declares a local `struct
ieee802154_hdr hdr` on the stack.
2. `ieee802154_hdr_pull()` calls `ieee802154_hdr_get_addr()` to parse
the source and destination addresses into this structure.
3. If the address mode is `IEEE802154_ADDR_NONE`,
`ieee802154_hdr_get_addr()` previously only set the `mode` field,
leaving the `pan_id` field containing uninitialized stack memory.
4. This uninitialized `pan_id` is later copied into a `struct
sockaddr_ieee802154` in `dgram_recvmsg()` via `ieee802154_addr_to_sa()`.
5. Finally, `move_addr_to_user()` copies the socket address structure to
user space, leaking the uninitialized bytes.

Fix this by using `memset` to zero out the address structure in
`ieee802154_hdr_get_addr()` when the mode is `IEEE802154_ADDR_NONE`.

When assoc_status not equal to IEEE802154_ASSOCIATION_SUCCESSFUL, the
return value assigned to either "-ERANGE" or "-EPERM" but this return
value will be overwritten to 0 after exiting the conditional scope.
So, jump to clear_assoc label to preserve the return value when

This is reported by Coverity Scan as "Unused value".

Subject: [PATCH 4109/5214] ieee802154: admin-gate legacy LLSEC dump operations

In net/ieee802154/netlink.c, the legacy IEEE802154_NL family ops table
builds the LLSEC dump entries (LLSEC_LIST_KEY, LLSEC_LIST_DEV,
LLSEC_LIST_DEVKEY, LLSEC_LIST_SECLEVEL) with IEEE802154_DUMP() which
sets no .flags, so generic netlink runs them ungated. The modern
nl802154 family admin-gates the equivalent reads via
NL802154_CMD_GET_SEC_KEY and friends with .flags = GENL_ADMIN_PERM.

Any local uid that can open AF_NETLINK / NETLINK_GENERIC can resolve
the "802.15.4 MAC" family and dump LLSEC_LIST_KEY on any wpan netdev
that has an LLSEC key installed; the dump handler writes the raw
16-byte AES-128 key bytes (IEEE802154_ATTR_LLSEC_KEY_BYTES, copied
verbatim from struct ieee802154_llsec_key.key) into the reply.
Recovering the AES key compromises 802.15.4 LLSEC link confidentiality
and authenticity, since LLSEC uses CCM* and the same key authenticates
and encrypts frames.

Impact: any local uid with no capabilities can read the raw 16-byte
AES-128 LLSEC key from the kernel keytable on any wpan netdev that has
an administrator-installed LLSEC key, by issuing an LLSEC_LIST_KEY
dump on the legacy IEEE802154_NL generic-netlink family.

Introduce IEEE802154_DUMP_PRIV() mirroring IEEE802154_DUMP() but
setting .flags = GENL_ADMIN_PERM, and use it for the four LLSEC dump
entries. LIST_PHY and LIST_IFACE retain IEEE802154_DUMP() because the
modern nl802154 family exposes their equivalents to unprivileged
readers by design (NL802154_CMD_GET_WPAN_PHY and
NL802154_CMD_GET_INTERFACE carry "can be retrieved by unprivileged
users" annotations).

Subject: [PATCH 4110/5214] ieee802154: allow legacy LLSEC ADD/DEL ops to pass
 strict validation

The LLSEC ADD/DEL doit handlers under the legacy IEEE802154_NL family
consume IEEE802154_ATTR_LLSEC_KEY_BYTES and
IEEE802154_ATTR_LLSEC_KEY_USAGE_COMMANDS, both declared in
net/ieee802154/nl_policy.c as bare length entries with no .type
(defaulting to NLA_UNSPEC). Generic netlink strict validation rejects
all NLA_UNSPEC attributes via validate_nla(), so every LLSEC_ADD_KEY,
LLSEC_DEL_KEY, LLSEC_ADD_DEV, LLSEC_DEL_DEV, LLSEC_ADD_DEVKEY,
LLSEC_DEL_DEVKEY, LLSEC_ADD_SECLEVEL, and LLSEC_DEL_SECLEVEL request
fails at the dispatcher with "Unsupported attribute" before reaching
the handler.

The doit path has been silently dead since strict validation became
the default for genl families that do not opt out. The dump path is
unaffected because dump requests carry no LLSEC attributes to
validate, which is why the LLSEC_LIST_KEY read remained reachable
(patch 1/2). Introduce IEEE802154_OP_RELAXED() mirroring
IEEE802154_OP() but with .validate = GENL_DONT_VALIDATE_STRICT, and
use it for the eight legacy LLSEC mutate ops so admin-driven LLSEC
configuration via the legacy interface works again.

Refactor the control flow in id_mode_to_cifs_acl() to reduce nesting and
prevent error code overwriting.

Instead of wrapping the call to ops->set_acl() in a conditional block,
introduce early exits (goto id_mode_to_cifs_acl_exit) when build_sec_desc()
fails or ops->set_acl is NULL. This ensures that any actual error returned
by build_sec_desc() is not overwritten with -EOPNOTSUPP.

Subject: [PATCH 4113/5214] md/raid1: fix writes_pending and barrier reference
 leaks on write failures

raid1_make_request() acquires a writes_pending reference with
md_write_start() before calling raid1_write_request(). Several failure
paths in raid1_write_request() complete the bio and return without
reaching the normal write completion path, causing the corresponding
md_write_end() to be skipped.

Make raid1_write_request() return a status indicating whether the write
request was successfully queued. This allows raid1_make_request() to
call md_write_end() when raid1_write_request() fails.

Additionally, if wait_blocked_rdev() fails after wait_barrier()
succeeds, the associated barrier reference is not released.

Call allow_barrier() before returning from that path to keep the barrier
accounting balanced.

Subject: [PATCH 4114/5214] md/raid10: fix writes_pending leak on write request
 failures

raid10_make_request() acquires a writes_pending reference with
md_write_start() before dispatching write requests. Several failure
paths in raid10_write_request() complete the bio and return without
reaching the normal write completion path, causing the corresponding
md_write_end() to be skipped.

Make raid10_write_request() return a status indicating whether the write
request was successfully queued. This allows raid10_make_request() to
release the writes_pending reference with md_write_end() when a write
request fails.

Subject: [PATCH 4115/5214] md/raid10: fix writes_pending and barrier reference
 leaks on discard failures

raid10_make_request() acquires a writes_pending reference with
md_write_start() before calling raid10_handle_discard(). Several failure
paths in raid10_handle_discard() complete the bio and return without
releasing the corresponding reference, causing md_write_end() to be
skipped.

Call md_write_end() before returning from these failure paths to keep
writes_pending accounting balanced.

Additionally, discard split allocation failures can occur after
wait_barrier() succeeds. Those paths return without calling
allow_barrier(), leaking the associated barrier reference.

Release the barrier before returning from those paths.

Subject: [PATCH 4116/5214] md/raid1: simplify raid1_write_request() error
 handling

raid1_write_request() increments rdev->nr_pending before checking the
badblocks and then immediately decrements it again when a device is
skipped. Move the increment until after the checks succeed so the
reference accounting is easier to follow.

Consolidate the failure paths so that each error label releases exactly
the resources acquired up to that point. err_dec_pending drops pending
references and frees the r1bio, while err_allow_barrier handles the
barrier release before returning.

When a REQ_ATOMIC write cannot be satisfied due to a badblock range,
complete the bio with BLK_STS_NOTSUPP rather than reporting an I/O
error, since the operation is unsupported rather than having failed
during I/O.

Rename max_write_sectors to max_sectors and remove the redundant local
copy.

Subject: [PATCH 4117/5214] md/raid5: account discard IO

Raid5 handles discard bios internally through make_discard_request() and
never passes them through md_account_bio(). As a result, discard IO is
missing the md-device iostat accounting that normal raid5 IO and discard
IO in other raid levels get from md_account_bio().

Before accounting the bio, trim the request to the full data stripes that
raid5 will actually discard. The first full stripe is the ceiling of the
bio start divided by data-stripe sectors, and the last full stripe is the
floor of the bio end divided by data-stripe sectors. Account that exact
MD logical full-stripe range, then restore the original iterator so bio
completion and iostat still cover the original request.

Subject: [PATCH 4118/5214] md/raid5: validate discard support at request time

Raid5 used to disable discard limits when devices_handle_discard_safely
was not set or when stacked member limits could not support a full-stripe
discard. That hides discard from userspace before raid5 can decide whether
a request can be handled safely.

Follow other virtual drivers and advertise a UINT_MAX discard limit for the
md device. Cache lower discard support in r5conf when setting queue limits,
and reject unsupported discard bios before queuing stripe work.

Subject: [PATCH 4119/5214] md/raid5: always convert llbitmap bits for discard

llbitmap discard is useful even when no underlying member device supports
it. The discard still converts the llbitmap range to unwritten, so later
reads and recovery do not rely on stale parity for that range.

Let llbitmap discard bypass the raid5 lower discard support check. If lower
discard is not safe or not supported, complete the accounted clone after
md_account_bio() so the llbitmap conversion callbacks run without member
discard bios.

Subject: [PATCH 4120/5214] md/raid1: honor REQ_NOWAIT when waiting for behind
 writes

raid1 supports REQ_NOWAIT reads by avoiding waits in the barrier path
through wait_read_barrier(). However, a read can still block on a
WriteMostly device when the array uses a bitmap and there are
outstanding behind writes.

In that case raid1 unconditionally calls wait_behind_writes(), which
may sleep until all behind writes complete. As a result, a REQ_NOWAIT
read can block despite the caller explicitly requesting non-blocking
behavior.

This ensures that raid1 consistently honors REQ_NOWAIT reads across all
paths that may otherwise wait for behind writes.

Subject: [PATCH 4121/5214] md/raid1: free r1_bio when REQ_NOWAIT is set and
 read would block on retry

When a read is retried, raid1_read_request() may be called with a
pre-allocated r1_bio. If wait_read_barrier() fails for a REQ_NOWAIT
read, the bio is completed and the function returns immediately. In this
case the existing r1_bio is leaked.

This fixes a leak of pre-allocated r1_bio structures for retried reads.

Subject: [PATCH 4129/5214] netfilter: nft_meta_bridge: add validate callback
 for get operations

Blamed commit added NFT_META_BRI_IIFHWADDR to the set validate callback,
yet this is a get operation.

Add a get validate callback and move the NFT_META_BRI_IIFHWADDR key
there.

AFAICS this is harmless, NFT_META_BRI_IIFHWADDR can deal with a NULL
input device and the set handler ignores a NFT_META_BRI_IIFHWADDR
operation, but it allows to read 4 bytes off bridge skb->cb[].

Subject: [PATCH 4132/5214] netfilter: nf_conntrack_expect: use conntrack GC to
 reap expectations

This patch replaces the timer API by GC worker approach for
expectations, as it already happened in many other subsystems.

Use the existing conntrack GC worker to iterate over the local list of
expectations in the master conntrack to reap expired expectations.
Check IPS_HELPER_BIT to run GC for expectations, set it on for nft_ct
expectation which nevers sets it. Hold the expectation spinlock while
iterating over the master conntrack expectation list to synchronize with
nf_ct_remove_expectations(). This also performs runtime packet path
garbage collection through the expectation insertion and lookup
functions while walking over one of the chains of the global expectation
hashtables. Unconfirmed conntrack entries are skipped since ct->ext can
be reallocated and dying are skipped since those will be gone soon.
Set on IPS_HELPER_BIT if the helper ct extension is added, then the new
GC worker does not need to bump the ct refcount to check if the ct->ext
helper is available.

This removes the extra bump on the refcount for expectation timers, this
allows to remove several nf_ct_expect_put() calls after the unlink,
after this update only refcount remains at 1 while on the expectation
hashes.

This patch implicitly addresses a race with the existing timer API
allowing an expectation to access a stale exp->master pointer which has
been already released when expectation removal loses races with an
expiring timer, ie. timer_del() reporting false.

Add a new NF_CT_EXPECT_DEAD flag to reap this expectation via GC. This
is needed by nf_conntrack_unexpect_related() which is called in error
paths to invalidate newly created expectations that has been added into
the hashes. These expectactions cannot be inmediately released as GC or
nf_ct_remove_expectations() could race to make it. On expectation
insert, the runtime GC reaps stale expectations before checking the
expectation limit set by policy.

Set current timestamp in nf_ct_expect_alloc(), then add the expectation
policy timeout (or custom timeout specified added on top of this) to
specify the expectation lifetime.

Commit 207696b17f38 ("tpm: use a map for tpm2_calc_ordinal_duration()")
inadvertently reduced the timeout for TPM2 key creation commands
(`CREATE_PRIMARY`, `CREATE`, `CREATE_LOADED`) from 300 seconds to 30
seconds.

This causes intermittent timeout failures, with several failures observed
across hundreds of test runs on some Intel platforms using Infineon
SLB9670 and SLB9672 TPM modules. Restore the timeout to 300 seconds to
avoid spurious failures.

Subject: [PATCH 4136/5214] tpm: Initialize name_size_alg for non-NULL name in
 tpm_buf_append_name()

tpm_buf_append_name() supports callers passing a pre-computed name
for handles. When name is non-NULL, the code skips the
tpm2_read_public() path but leaves name_size_alg uninitialized
before it is used as the memcpy size argument.

No current in-tree caller passes a non-NULL name, but future use
cases such as name caching would exercise this path. Initialize
name_size_alg by calling name_size() on the caller-provided name,
sharing the error check and assignment with the existing
tpm2_read_public() path. This prevents unmasking a latent bug when
the non-NULL name path is eventually used.

Subject: [PATCH 4137/5214] tpm: tpm_tis_spi: Use wait_woken() in
 wait_for_tmp_stat()

wait_event_interruptible_timeout() evaluates its condition after setting
the current task state to TASK_INTERRUPTIBLE.

With CONFIG_DEBUG_ATOMIC_SLEEP this triggers a warning when the IRQ wait
path is used:

    tpm_tis_status()
      tpm_tis_spi_read_bytes()
        tpm_tis_spi_transfer_full()
          spi_bus_lock()
            mutex_lock()

Address this with the following measures:

1. Call wait_tpm_stat_cond() only while tasking is running.
2. Use wait_woken() to wait for changes.

Subject: [PATCH 4138/5214] tpm_crb: Check ACPI_COMPANION() against NULL during
 probe

Every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device's ACPI companion
object need to verify its presence.

Accordingly, add a requisite ACPI_COMPANION() check against NULL to the
tpm_crb driver.

Subject: [PATCH 4140/5214] tpm: tpm_tis: Add settle time for some TPMs

Some TPMs fail to grant locality when requested immediately after being
relinquished. In this case, the TPM_ACCESS_REQUEST_USE bit of the
TPM_ACCESS register is cleared immediately without setting
TPM_ACCESS_ACTIVE_LOCALITY.

This issue can be seen at boot since tpm_chip_start, called right
after locality is relinquished, will fail. This causes the probe to
fail:

tpm_tis MSFT0101:00: probe with driver tpm_tis failed with error -1

This occurs on some older Dell Latitudes. For the Nuvoton TPM used in
these machines, add a delay after locality is relinquished.

Subject: [PATCH 4141/5214] tpm: tpm2-sessions: wait for async KPP completion
 in tpm_buf_append_salt

tpm_buf_append_salt() in drivers/char/tpm/tpm2-sessions.c calls
crypto_kpp_generate_public_key() and crypto_kpp_compute_shared_secret()
without installing a completion callback, discards both return values,
and immediately frees the kpp_request via kpp_request_free(). When the
resolved ecdh-nist-p256 KPP backend is asynchronous (atmel-ecc, HPRE,
keembay-ocs), either operation returns -EINPROGRESS and the deferred
completion worker dereferences the freed request.

The path fires automatically from the hwrng_fillfn kernel thread via
tpm_get_random -> tpm2_get_random -> tpm2_start_auth_session ->
tpm_buf_append_salt on every entropy poll, without any userland action.

Install crypto_req_done as the completion callback, wrap both KPP
operations in crypto_wait_req(), and propagate errors to the caller.
The wait is a no-op for synchronous backends.

commit 746d9e9f62a6 ("tpm: tpm_crb_ffa: try to probe tpm_crb_ffa when it's built-in")
probe tpm_crb_ffa forcefully when it's built-in to integrate with IMA.

However, IMA now provides the IMA_INIT_LATE_SYNC build option, which
initialises IMA at the late_initcall_sync level, so this change is no
longer required.

Subject: [PATCH 4143/5214] tpm: fix event_size output in
 tpm1_binary_bios_measurements_show

Commit 186d124f07da ("tpm_eventlog.c: fix binary_bios_measurements")
split the output to write the endian-converted event header first and
then the variable-length event data.

However, the split was at sizeof(struct tcpa_event) - 1, even though
event_data was a zero-length array, and later a flexible array member,
both of which already excluded the event data.

Therefore, the current code writes the first three bytes of event_size
from the endian-converted header and then the last byte from the raw
header, which can emit a corrupted event_size on PPC64, where
do_endian_conversion() maps to be32_to_cpu().

Split one byte later to write the full endian-converted header first,
followed by the variable-length event->event_data.

sashiko complained about possible teardown problem. The scenario

 CPU 0                              CPU 1
  imx_mu_isr()                   imx_mu_shutdown()
                                   imx_mu_xcr_rmw(priv, IMX_MU_RCR, 0, IMX_MU_xCR_RIEn(priv->dcfg->type, cp->idx));

      imx_mu_xcr_rmw(priv, IMX_MU_RCR, IMX_MU_xCR_RIEn(priv->dcfg->type, 0), 0);
                                   free_irq()

The RX event remains enabled because in this short window the RX event
was disabled in ->shutdown() while the interrupt was active and then
enabled again by the ISR while ->shutdown waited in free_irq().

This race requires timing and if happens can be problematic on shared
handlers if the "removed" channel triggers an interrupt. In this case
the irq-core will shutdown the interrupt with the "nobody cared"
message.

Introduce imx_mu_con_priv::shutdown to signal that the channel is
shutting down. This flag is set with the lock held (by
imx_mu_xcr_clr_shut()). The unmask side uses imx_mu_xcr_set_act() which
only enables the event if the channel has not been shutdown and
serialises on the same lock.

Subject: [PATCH 4146/5214] mailbox: imx: Use devm_pm_runtime_enable()

sashiko complained about early usage of the device while probe isn't
completed. This can be mitigated by delaying the pm_runtime_enable()
into the removal path instead doing it early. This ensures that in an
error case the device is removed (and imx_mu_shutdown()) before
pm_runtime_disable() so we don't have to do this manually.

For the order to work, lets move devm_mbox_controller_register() until
after the pm-runtime part. So the reverse order will be mbox-controller
removal followed by disabling pm runtime.

Use devm_pm_runtime_enable(), remove manual pm_runtime_disable()
invocations and move the pm_runtime handling in probe before
devm_mbox_controller_register().

Subject: [PATCH 4147/5214] mailbox: imx: use devm_of_platform_populate()

The driver uses of_platform_populate() but does not remove the added
devices on removal. This can lead to "double devices" on module removal
followed by adding the module again.

Use devm_of_platform_populate() to remove the populated devices once the
parent device is removed.

Subject: [PATCH 4148/5214] mailbox: imx: Use channel index instead of zero in
 imx_mu_specific_rx()

imx_mu_specific_rx() masks channel 0 and unmasks it again at the end of
the function. Given that at startup the channel index got unmasked it
should do the right job.

This here either unmasks the actual channel or another one but should
have no impact given that it reverses its doing at the end.

Peng Fan commented here:
| For specific rx channel, whether it is i.MX8 SCU or i.MX ELE, actually there is
| only 1 channel as of now, but it seems better to use cp->idx in case more
| channels in future.

Use the channel index instead of zero.

Subject: [PATCH 4149/5214] mailbox: imx: Start splitting the IRQ handler in
 primary and threaded handler

Split the mailbox irq handling into a primary handler (imx_mu_isr()) and
a threaded handler (imx_mu_isr_th()). The primary handler masks the
interrupt event so the threaded handler can run without raising the
interrupt again.

The goal here is to invoke the mailbox core functions (such as
mbox_chan_received_data(), mbox_chan_txdone()) in preemptible context which is
made possible by using an threaded interrupt handler. This in turn means that
mailbox's client callbacks are invoked in preemptible context, too. This then
allows the mailbox client callback to skip an indirection via a workqueue if
it requries preemptible callback.

As a first step, prepare the logic and move TX handling part.

Subject: [PATCH 4150/5214] mailbox: imx: Move the RX part of the mailbox into
 the threaded handler

Move RX callback handling into the threaded handler. This is similar to
the TX side except that we explicitly mask the source interrupt in the
primary handler and unmask it in the threaded handler again after
success. This was done automatically in the TX part.

The masking/ unmasking can be removed from imx_mu_specific_rx() since it
already happens in the primary/ threaded handler before invoking the
channel specific callback.

Move RX channel handling into threaded handler.

Subject: [PATCH 4152/5214] mailbox: imx: Don't force-thread the primary
 handler

The primary interrupt handler (imx_mu_isr()) no longer invokes any
callbacks it only masks the interrupt source and returns. In a
forced-threaded environment the IRQ-core will force-thread the primary
handler which can be avoided.

The primary handler uses a spinlock_t to protect the RMW operation in
imx_mu_xcr_rmw() - nothing that may introduce long latencies.

The lock can be turned into a raw_spinlock_t and then the primary
handler can run in hardirq context even on PREEMPT_RT skipping one
thread.

Make struct imx_mu_priv::xcr_lock a raw_spinlock_t and skip
force-threading the primrary handler by marking it IRQF_NO_THREAD.

Subject: [PATCH 4153/5214] 9p: avoid putting oldfid in p9_client_walk() error
 path

When p9_client_walk() is called with clone set to false, fid aliases
oldfid. If the walk subsequently fails after the request has been sent,
the error path jumps to clunk_fid, which currently calls p9_fid_put(fid)
unconditionally.

This drops a reference to oldfid even though ownership of oldfid remains
with the caller. If this is the last reference, oldfid can be clunked and
destroyed while the caller still expects it to be valid. A later use or
put of oldfid can then trigger a use-after-free or refcount underflow.

Fix this by only putting fid in the clunk_fid error path when it does not
alias oldfid, matching the existing guard in the error path below.

This can be triggered when a multi-component walk is split into multiple
p9_client_walk() calls and a later non-cloning walk fails. A reproducer
and refcount warning logs are available on request.

Fixes: b48dbb998d70 ("9p fid refcount: add p9_fid_get/put wrappers")

success and ERR_PTR() only with negative error codes for failure.

Return NULL instead of passing to ERR_PTR while err is zero
Fixes smatch warnings:
  fs/9p/vfs_inode_dotl.c:420 v9fs_vfs_mkdir_dotl() warn: passing zero to 'ERR_PTR'
  fs/9p/vfs_inode.c:695 v9fs_vfs_mkdir() warn: passing zero to 'ERR_PTR'

The v9fs_vfs_mkdir() code was further simplified because v9fs_create()
can never return NULL, so we do not need to check for fid being set
separately, and the error path can be a simple return immediately after
v9fs_create() failure.
There is no intended functional change.

Fixes: 88d5baf69082 ("Change inode_operations.mkdir to return struct dentry *")

Subject: [PATCH 4155/5214] 9p: Cache negative dentries for lookup performance

Not caching negative dentries can result in poor performance for
workloads that repeatedly look up non-existent paths. Each such
lookup triggers a full 9P transaction with the server, adding
unnecessary overhead.

A typical example is source compilation, where multiple cc1 processes
are spawned and repeatedly search for the same missing header files
over and over again.

This change enables caching of negative dentries, so that lookups for
known non-existent paths do not require a full 9P transaction. The
cached negative dentries are retained for a configurable duration
(expressed in milliseconds), as specified by the ndentry_timeout
field in struct v9fs_session_info. If set to -1, negative dentries
are cached indefinitely.

This optimization reduces lookup overhead and improves performance for
workloads involving frequent access to non-existent paths.

Subject: [PATCH 4156/5214] 9p: Add mount option for negative dentry cache
 retention

Introduce a new mount option, negtimeout, for v9fs that allows users
to specify how long negative dentries are retained in the cache. The
retention time can be set in milliseconds (e.g. negtimeout=10000 for
a 10secs retention time) or a negative value (e.g. negtimeout=-1) to
keep negative entries until the buffer cache management removes them.

For consistency reasons, this option should only be used in exclusive
or read-only mount scenarios, aligning with the cache=loose usage.

Subject: [PATCH 4158/5214] 9p: Enable symlink caching in page cache

Currently, when cache=loose is enabled, file reads are cached in the
page cache, but symlink reads are not. This patch allows the results
of p9_client_readlink() to be stored in the page cache, eliminating
the need for repeated 9P transactions on subsequent symlink accesses.

This change improves performance for workloads that involve frequent
symlink resolution.

Subject: [PATCH 4160/5214] net/9p: fix race condition on rdma->state in
 trans_rdma.c

The rdma->state field is modified without holding req_lock in both
recv_done() and p9_cm_event_handler(), while rdma_request() accesses
the same field under the req_lock spinlock. This inconsistent locking
creates a race condition:

- recv_done() running in softirq completion context sets
  rdma->state = P9_RDMA_FLUSHING without acquiring req_lock

- p9_cm_event_handler() modifies rdma->state at multiple points
  (ADDR_RESOLVED, ROUTE_RESOLVED, ESTABLISHED, CLOSED) without
  req_lock

- rdma_request() uses spin_lock_irqsave(&rdma->req_lock, flags) to
  protect the read-modify-write of rdma->state

The race can cause lost state transitions: recv_done() or the CM
event handler could set state to FLUSHING/CLOSED while rdma_request()
is concurrently checking or modifying state under the lock, leading to
the FLUSHING transition being silently overwritten by CLOSING. This
corrupts the connection state machine and can cause use-after-free on
RDMA request objects during teardown.

Fix by adding req_lock protection to all rdma->state modifications in
recv_done() and p9_cm_event_handler(), matching the pattern already
used in rdma_request(). Use spin_lock_irqsave/spin_unlock_irqrestore
in the CM event handler since it can race with recv_done() which runs
in softirq context.

Tested with a kernel module that races two threads (simulating
rdma_request and recv_done/CM handler) on rdma->state with proper
locking: 5.5M+ FLUSHING writes over 27M iterations with 0 lost
transitions.

Fixes: 473c7dd1d7b5 ("9p/rdma: remove useless check in cm_event_handler")

Subject: [PATCH 4161/5214] 9p: skip nlink update in cacheless mode to fix
 WARN_ON

v9fs_dec_count() unconditionally calls drop_nlink() on regular files,
even when the inode's nlink is already zero. In cacheless mode the
client refetches inode metadata from the server (the source of truth)
on every operation, so by the time v9fs_remove() returns, the locally
cached nlink may already reflect the post-unlink value:

  1. Client initiates unlink, server processes it and sets nlink to 0
  2. Client refetches inode metadata (nlink=0) before unlink returns
  3. Client's v9fs_remove() completes successfully
  4. Client calls v9fs_dec_count() which calls drop_nlink() on nlink=0

This race is easily triggered under heavy unlink workloads, such as
stress-ng's unlink stressor, producing the following warning:

  WARNING: fs/inode.c:417 at drop_nlink+0x4c/0xc8

In cacheless mode the server is authoritative and the inode is on its
way out, so locally adjusting nlink buys nothing. Skip v9fs_dec_count()
entirely when neither CACHE_META nor CACHE_LOOSE is set, which both
avoids the warning and removes a class of nlink races (two concurrent
unlinkers observing nlink > 0 and both calling drop_nlink()) that an
nlink == 0 guard alone would only narrow rather than close.

Commit 2b6e72ed747f ("9P: Add memory barriers to protect request

p9_client_rpc() waits for req->status, pairing with the write barrier in
p9_client_cb(). The virtio zero-copy wait path was missed.

Add the same read barrier after the zero-copy wait before reading the
completed request.

Subject: [PATCH 4164/5214] locking/rt: Fix the incorrect RCU protection in
 rt_spin_unlock()

rt_spin_unlock() releases the RCU protection before unlocking the
lock. That opens the door for the following UAF scenario:

 T1					T2
 spin_lock(&p->lock);		rcu_read_lock();
 invalidate(p);			p = rcu_dereference(ptr);
 rcu_assign_pointer(ptr, NULL);	if (!p) return;
 spin_unlock(&p->lock);		spin_lock(&p->lock)
 				   lock(&lock->lock);
				   rcu_read_lock();
 kfree_rcu(p);			rcu_read_unlock();
				....
				spin_unlock(&p->lock)
				  rcu_read_unlock(); // Ends grace period
 rcu_do_batch()
   kfree(p);
			    UAF ->	  rt_mutex_cmpxchg_release(&lock->lock...)

Regular spinlocks keep preemption disabled accross the unlock operation,
which provides full RCU protection, but the RT substitution fails to
resemble that. Same applies for the rwlock substitution.

Move the rcu_read_unlock() invocation past the unlock operations to match
the non-RT semantics. This makes it asymmetric vs. rt_xxx_lock(), but
that's harmless as the caller needs to hold RCU read lock across the lock
operation. The migrate_enable() call stays before the unlock operation
because there is no per CPU operation in the unlock path which would
require migration to be kept disabled.

Subject: [PATCH 4165/5214] irqchip/crossbar: Use correct index in
 crossbar_domain_free()

crossbar_domain_free() resets the domain data and then uses the nulled
out irq_data->hwirq member as index to reset the irq_map[] entry and to
write the relevant crossbar register with a safe entry. That means it
never frees the correct index and keeps the crossbar register connection
to the source interrupt active.

If it would not reset the domain data, then this would be even worse as
irq_data->hwirq holds the source interrupt number, but both the map and
register index need the corresponding GIC SPI number and not the source
interrupt number. This might even result in an out of bounds access as
the source interrupt number can be higher than the maximal index space.

Fix this by using the GIC SPI index from the parent domain's irq_data.

Subject: [PATCH 4167/5214] drm/nouveau/acr: fix missing nvkm_done() in error
 path of nvkm_acr_oneinit()

In nvkm_acr_oneinit(), nvkm_kmap(acr->wpr) is invoked unconditionally
at line 309 to obtain a mapping reference. Additionally, when both
acr->wpr_fw and acr->wpr_comp are present, a second nvkm_kmap() is
called inside the conditional block. Both mappings are expected to be
released by nvkm_done(acr->wpr) at line 320 before the function returns
successfully.

However, when a mismatch is detected during the loop within the
conditional block, the function returns -EINVAL at line 318 without
calling nvkm_done(). This results in a leak of the kmap reference(s)
acquired earlier.

Fix the issue by invoking nvkm_done(acr->wpr) prior to the early return
to ensure proper release of the mapping references.

Subject: [PATCH 4168/5214] drm/nouveau: fix reversed error cleanup order in
 ucopy functions

nouveau_uvmm_vm_bind_ucopy() and nouveau_exec_ucopy() place their error
cleanup labels in allocation order rather than reverse allocation order.
On a u_memcpya() failure for in_sync.s, the goto to err_free_ops (or
err_free_pushs) frees the first allocation and then falls through to
err_free_ins, which calls u_free() on args->in_sync.s.

Since args->in_sync.s still holds the ERR_PTR returned by the failed
u_memcpya(), and ERR_PTR values are not caught by ZERO_OR_NULL_PTR(),
kvfree() proceeds to dereference it, which can result in a kernel oops.
A failure for out_sync.s instead jumps to err_free_ins and skips freeing
the first allocation, leading to a memory leak.

Fix by swapping the cleanup label order so resources are freed in the
correct reverse allocation sequence.

Subject: [PATCH 4169/5214] mm/alloc_tag: replace fixed-size early PFN array
 with dynamic linked list

Pages allocated before page_ext is available have their codetag left
uninitialized.  Track these early PFNs and clear their codetag in
clear_early_alloc_pfn_tag_refs() to avoid "alloc_tag was not set" warnings
when they are freed later.

Currently a fixed-size array of 8192 entries is used, with a warning if
the limit is exceeded.  However, the number of early allocations depends
on the number of CPUs and can be larger than 8192.

Replace the fixed-size array with a dynamically allocated linked list of
pfn_pool structs.  Each node is allocated via alloc_page() and mapped to a
pfn_pool containing a next pointer, an atomic slot counter, and a PFN
array that fills the remainder of the page.

The tracking pages themselves are allocated via alloc_page(), which would
trigger __pgalloc_tag_add() -> alloc_tag_add_early_pfn() and recurse
indefinitely.  Introduce __GFP_NO_CODETAG (reuses the %__GFP_NO_OBJ_EXT
bit) and pass gfp_flags through pgalloc_tag_add() so that the early path
can skip recording allocations that carry this flag.

Subject: [PATCH 4170/5214] alloc_tag: fix use-after-free in /proc/allocinfo
 after module unload

allocinfo_start() only reinitializes the codetag iterator at position 0.
For subsequent reads (position > 0), it reuses cached iterator state from
the previous batch.  allocinfo_stop() drops mod_lock between read batches,
which allows module unload to complete and free the module memory that the
cached iterator still references:

  CPU0 (read)                        CPU1 (rmmod)
  ----                               ----
  allocinfo_start(pos=0)
    down_read(mod_lock)
    allocinfo_show()
    ...
  allocinfo_stop()
    up_read(mod_lock)
                                     codetag_unload_module()
                                       kfree(cmod)
                                       release_module_tags()
                                     ...
                                     free_mod_mem()
  allocinfo_start(pos=N)
    down_read(mod_lock)
    // reuses cached iter, skips re-init
  allocinfo_show()
    ct->filename   <-- UAF

After free_mod_mem() frees the module's .rodata, allocinfo_show()
dereferences ct->filename, ct->function which point there.

Save the iterator state in allocinfo_next() and resume from it in
allocinfo_start() with codetag_next_ct(), which detects module removal via
idr_find() returning NULL and skips to the next module.

Subject: [PATCH 4171/5214] lib: split codetag_lock_module_list()

Letting a function argument indicate whether a lock or unlock operation
should be performed is incompatible with compile-time analysis of locking
operations by sparse and Clang.  Hence, split codetag_lock_module_list()
into two functions: a function that locks cttype->mod_lock and another
function that unlocks cttype->mod_lock.  No functionality has been
changed.  See also commit 916cc5167cc6 ("lib: code tagging framework").

Subject: [PATCH 4173/5214] mm/page_alloc: only update NUMA min ratios on
 sysctl write

The sysctl handlers for min_unmapped_ratio and min_slab_ratio invoke
setup_min_unmapped_ratio() and setup_min_slab_ratio() unconditionally
after proc_dointvec_minmax(), even for read operations.

These setup functions first zero all per-NUMA node thresholds
(min_unmapped_pages and min_slab_pages) before recalculating them.
Reading /proc sysctl entries therefore temporarily resets node reclaim
thresholds to zero, which may disturb the behavior of __node_reclaim() and
node_reclaim() during the recomputation.

Fix this by only calling the setup functions when the sysctl is actually
written (write == 1), matching the behavior of existing sysctl handlers
like min_free_kbytes and watermark_scale_factor.

This only affects systems with CONFIG_NUMA.

Subject: [PATCH 4174/5214] mm/khugepaged: generalize hugepage_vma_revalidate
 for mTHP support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Patch series "khugepaged: add mTHP collapse support", v19.

The following series provides khugepaged with the capability to collapse
anonymous memory regions to mTHPs.

To achieve this we generalize the khugepaged functions to no longer depend
on PMD_ORDER.  Then during the PMD scan, we use a bitmap to track
individual pages that are occupied (!none/zero).  After the PMD scan is
done, we use the bitmap to find the optimal mTHP sizes for the PMD range.
The restriction on max_ptes_none is removed during the scan, to make sure
we account for the whole PMD range in the bitmap.  When no mTHP size is
enabled, the legacy behavior of khugepaged is maintained.

We currently only support max_ptes_none values of 0 or HPAGE_PMD_NR - 1
(ie 511).  If any other value is specified, the kernel will emit a warning
and mTHP collapse will default to max_ptes_none=0.  If a mTHP collapse is
attempted, but contains swapped out, or shared pages, we don't perform the
collapse.

It is now also possible to collapse to mTHPs without requiring the PMD THP
size to be enabled.  These limitations are to prevent collapse "creep"
behavior.  This prevents constantly promoting mTHPs to the next available
size, which would occur because a collapse introduces more non-zero pages
that would satisfy the promotion condition on subsequent scans.

Patch 1-2:   Generalize hugepage_vma_revalidate and alloc_charge_folio
             for arbitrary orders.
Patch 3:     Rework max_ptes_* handling into helper functions
Patch 4:     Generalize __collapse_huge_page_* for mTHP support
Patch 5:     Require collapse_huge_page to enter/exit with the lock dropped
Patch 6:     Generalize collapse_huge_page for mTHP collapse
Patch 7:     Skip collapsing mTHP to smaller orders
Patch 8-9:   Add per-order mTHP statistics and tracepoints
Patch 10:    Introduce collapse_possible_orders helper functions
Patch 11-13: Introduce bitmap and mTHP collapse support, fully enabled
Patch 14:    Documentation

Testing:
- Built for x86_64, aarch64, ppc64le, and s390x
- ran all arches on test suites provided by the kernel-tests project
- internal testing suites: functional testing and performance testing
- selftests mm
- I created a test script that I used to push khugepaged to its limits
   while monitoring a number of stats and tracepoints. The code is
   available here[1] (Run in legacy mode for these changes and set mthp
   sizes to inherit)
   The summary from my testings was that there was no significant
   regression noticed through this test. In some cases my changes had
   better collapse latencies, and was able to scan more pages in the same
   amount of time/work, but for the most part the results were consistent.
- redis testing. I did some testing with these changes along with my defer
  changes (see followup [2] post for more details). We've decided to get
  the mTHP changes merged first before attempting the defer series.
- some basic testing on 64k page size.
- lots of general use.


This patch (of 14):

For khugepaged to support different mTHP orders, we must generalize this
to check if the PMD is not shared by another VMA and that the order is
enabled.

We cannot collapse VMA regions that do not span the full PMD.  This is due
to the potential of the PMD being shared by another VMA which leaves us
vulnerable to race conditions if neighboring VMAs are resized.  Always
check the PMD order here to ensure its not shared by another VMA.  We'd
need to lock all VMAs in the PMD range to support this which may lead to
increased lock contention and code complexity.

No functional change in this patch.  Also correct a comment about the
functionality of the revalidation and fix a double space issues.

Subject: [PATCH 4176/5214] mm/khugepaged: rework max_ptes_* handling with
 helper functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The following cleanup reworks all the max_ptes_* handling into helper
functions.  This increases the code readability and will later be used to
implement the mTHP handling of these variables.

With these changes we abstract all the madvise_collapse() special casing
(do not respect the sysctls) away from the functions that utilize them.
And will be used later in this series to cleanly restrict the mTHP
collapse behavior.

No functional change is intended; however, we are now only reading the
sysfs variables once per scan, whereas before these variables were being
read on each loop iteration.

Subject: [PATCH 4177/5214] mm/khugepaged: generalize __collapse_huge_page_*
 for mTHP support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

generalize the order of the __collapse_huge_page_* and collapse_max_*
functions to support future mTHP collapse.

The current mechanism for determining collapse with the
khugepaged_max_ptes_none value is not designed with mTHP in mind.  This
raises a key design issue: if we support user defined max_pte_none values
(even those scaled by order), a collapse of a lower order can introduces
an feedback loop, or "creep", when max_ptes_none is set to a value greater
than HPAGE_PMD_NR / 2.  [1]

With this configuration, a successful collapse to order N will populate
enough pages to satisfy the collapse condition on order N+1 on the next
scan.  This leads to unnecessary work and memory churn.

To fix this issue introduce a helper function that will limit mTHP
collapse support to two max_ptes_none values, 0 and HPAGE_PMD_NR - 1.
This effectively supports two modes: [2]

- max_ptes_none=0: never collapses if it encounters an empty PTE or a PTE
  that maps the shared zeropage. Consequently, no memory bloat.
- max_ptes_none=511 (on 4k pagesz): Always collapse to the highest
  available mTHP order.

This removes the possibility of "creep", and a warning will be emitted if
any non-supported max_ptes_none value is configured with mTHP enabled.
Any intermediate value will default mTHP collapse to max_ptes_none=0.

mTHP collapse will not honor the khugepaged_max_ptes_shared or
khugepaged_max_ptes_swap parameters, and will fail if it encounters a
shared or swapped entry.

No functional changes in this patch; however it defines future behavior
for mTHP collapse.

Subject: [PATCH 4178/5214] mm/khugepaged: require collapse_huge_page to
 enter/exit with the lock dropped
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the collapse_huge_page function requires the mmap_read_lock to
enter with it held, and exit with it dropped.  This function moves the
unlock into its parent caller, and changes this semantic to requiring it
to enter/exit with it always unlocked.

In future patches, we need this expectation, as for in mTHP collapse, we
may have already dropped the lock, and do not want to conditionally check
for this by passing through the lock_dropped variable.

No functional change is expected as one of the first things the
collapse_huge_page function does is drop this lock before allocating the
hugepage.

Subject: [PATCH 4179/5214] mm/khugepaged: generalize collapse_huge_page for
 mTHP collapse
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pass an order to collapse_huge_page to support collapsing anon memory to
arbitrary orders within a PMD.  order indicates what mTHP size we are
attempting to collapse to.

For non-PMD collapse we must leave the anon VMA write locked until after
we collapse the mTHP-- in the PMD case all the pages are isolated, but in
the mTHP case this is not true, and we must keep the lock to prevent
access/changes to the page tables.  This can happen if the rmap walkers
hit a pmd_none while the PMD entry is currently unavailable due to being
temporarily removed during the collapse phase.

To properly establish the page table hierarchy without violating any
expectations from certain architectures (e.g.  MIPS), we must make sure to
have the PMD reinstalled before the PTEs, and hold both PTE/PMD locks
before calling update_mmu_cache_range() (if they are distinct locks).

Subject: [PATCH 4180/5214] mm/khugepaged: skip collapsing mTHP to smaller
 orders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

khugepaged may try to collapse a mTHP to a folio of equal or smaller size,
possibly resulting in a partially mapped source folio, which is undesired.
Skip these cases until we have a way to check if its ok to collapse to a
smaller mTHP size (like in the case of a partially mapped folio).  This
check is not done during the scan phase as the current collapse order is
unknown at that time.

This patch is inspired by Dev Jain's work on khugepaged mTHP support [1].

Subject: [PATCH 4181/5214] mm/khugepaged: add per-order mTHP collapse failure
 statistics
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add three new mTHP statistics to track collapse failures for different
orders when encountering swap PTEs, excessive none PTEs, and shared PTEs:

- collapse_exceed_swap_pte: Increment when mTHP collapse fails due to
	encountering a swap PTE.

- collapse_exceed_none_pte: Counts when mTHP collapse fails due to
  	exceeding the none PTE threshold for the given order

- collapse_exceed_shared_pte: Counts when mTHP collapse fails due to
	encountering a shared PTE.

These statistics complement the existing THP_SCAN_EXCEED_* events by
providing per-order granularity for mTHP collapse attempts.  The stats are
exposed via sysfs under
`/sys/kernel/mm/transparent_hugepage/hugepages-*/stats/` for each
supported hugepage size.

As we currently do not support collapsing mTHPs that contain a swap or
shared entry, those statistics keep track of how often we are encountering
failed mTHP collapses due to these restrictions.

We will add support for mTHP collapse for anonymous pages next; lets also
track when this happens at the PMD level within the per-mTHP stats.

Subject: [PATCH 4183/5214] mm/khugepaged: introduce collapse_possible_orders
 helper functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add collapse_possible_orders() to generalize THP order eligibility.  The
function determines which THP orders are permitted based on collapse
context (khugepaged vs madv_collapse).  We also add collapse_possible() as
a thin wrapper around collapse_possible_orders() that returns a bool
rather than the whole bitmap.

This consolidates collapse configuration logic and provides a clean
interface for future mTHP collapse support where the orders may be
different.

Subject: [PATCH 4184/5214] mm/khugepaged: introduce mTHP collapse support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enable khugepaged to collapse to mTHP orders.  This patch implements the
main scanning logic using a bitmap to track occupied pages and the
algorithm to find optimal collapse sizes.

Previous to this patch, PMD collapse had 3 main phases, a light weight
scanning phase (mmap_read_lock) that determines a potential PMD collapse,
an alloc phase (mmap unlocked), then finally heavier collapse phase
(mmap_write_lock).

To enabled mTHP collapse we make the following changes:

During PMD scan phase, track occupied pages in a bitmap.  When mTHP orders
are enabled, we remove the restriction of max_ptes_none during the scan
phase to avoid missing potential mTHP collapse candidates.  Once we have
scanned the full PMD range and updated the bitmap to track occupied pages,
we use the bitmap to find the optimal mTHP size.

Implement mthp_collapse() to walk forward through the bitmap and determine
the best eligible order for each naturally-aligned region.  The algorithm
starts at the beginning of the PMD range and, for each offset, tries the
highest order that fits the alignment.  If the number of occupied PTEs in
that region satisfies the max_ptes_none threshold for that order, a
collapse is attempted.  On failure, the order is decremented and the same
offset is retried at the next smaller size.  Once the smallest enabled
order is exhausted (or a collapse succeeds), the offset advances past the
region just processed, and the next attempt starts at the highest order
permitted by the new offset's natural alignment.

The algorithm works as follows:
    1) set offset=0 and order=HPAGE_PMD_ORDER
    2) if the order is not enabled, go to step (5)
    3) count occupied PTEs in the (offset, order) range using
       bitmap_weight_from()
    4) if the count satisfies the max_ptes_none threshold, attempt
       collapse; on success, advance to step (6)
    5) if a smaller enabled order exists, decrement order and retry
       from step (2) at the same offset
    6) advance offset past the current region and compute the next
       order from the new offset's natural alignment via __ffs(offset),
       capped at HPAGE_PMD_ORDER
    7) repeat from step (2) until the full PMD range is covered

mTHP collapses reject regions containing swapped out or shared pages.
This is because adding new entries can lead to new none pages, and these
may lead to constant promotion into a higher order mTHP.  A similar issue
can occur with "max_ptes_none > HPAGE_PMD_NR/2" due to a collapse
introducing at least 2x the number of pages, and on a future scan will
satisfy the promotion condition once again.  This issue is prevented via
the collapse_max_ptes_none() function which imposes the max_ptes_none
restrictions above.

We currently only support mTHP collapse for max_ptes_none values of 0 and
HPAGE_PMD_NR - 1.  resulting in the following behavior:

    - max_ptes_none=0: Never introduce new empty pages during collapse
    - max_ptes_none=HPAGE_PMD_NR-1: Always try collapse to the highest
      available mTHP order

Any other max_ptes_none value will emit a warning and default mTHP
collapse to max_ptes_none=0.  There should be no behavior change for PMD
collapse.

Once we determine what mTHP sizes fits best in that PMD range a collapse
is attempted.  A minimum collapse order of 2 is used as this is the lowest
order supported by anon memory as defined by THP_ORDERS_ALL_ANON.

Currently madv_collapse is not supported and will only attempt PMD
collapse.

We can also remove the check for is_khugepaged inside the PMD scan as the
collapse_max_ptes_none() function handles this logic now.

There are cases where, if an attempted collapse fails, all subsequent

Subject: [PATCH 4186/5214] mm/khugepaged: run khugepaged for all orders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If any order (m)THP is enabled we should allow running khugepaged to
attempt scanning and collapsing mTHPs.  In order for khugepaged to operate
when only mTHP sizes are specified in sysfs, we must modify the predicate
function that determines whether it ought to run to do so.

This function is currently called hugepage_pmd_enabled(), this patch
renames it to hugepage_enabled() and updates the logic to check to
determine whether any valid orders may exist which would justify
khugepaged running.

We must also update collapse_possible_orders() to check all orders if the
vma is anonymous and the collapse is khugepaged.

After this patch khugepaged mTHP collapse is fully enabled.

Subject: [PATCH 4188/5214] mm/khugepaged: fix PMD collapse swap PTE accounting

mthp_collapse() uses mthp_present_ptes to decide whether a range has
enough occupied PTEs to try collapse.  Swap PTEs accepted by
collapse_scan_pmd() are counted in unmapped, but are not represented in
mthp_present_ptes.

When lower orders are enabled, collapse_scan_pmd() relaxes max_ptes_none
so the scan can cover the whole PMD and build the bitmap.  mthp_collapse()
then checks the PMD-order candidate using the bitmap.

With max_ptes_none set to 0, a range with 511 present PTEs and one swap
PTE no longer reaches collapse_huge_page(), even though PMD collapse can
handle swap PTEs up to max_ptes_swap.

Account unmapped PTEs only for PMD order.  PMD collapse supports swap PTEs
through max_ptes_swap, while lower-order mTHP collapse does not currently
support non-present PTEs.  Keep non-present PTEs out of the lower-order
eligibility check.

Patch series "Remove CONFIG_READ_ONLY_THP_FOR_FS and enable file THP for
writable files", v6.


This patch (of 14):

collapse_file() requires FSes supporting large folio with at least
PMD_ORDER, so replace the READ_ONLY_THP_FOR_FS check with that.
MADV_COLLAPSE ignores shmem huge config, so exclude the check for shmem.

While at it, replace VM_BUG_ON with VM_WARN_ON_ONCE.

Add a helper function mapping_pmd_folio_support() for FSes supporting
large folio with at least PMD_ORDER.

Subject: [PATCH 4190/5214] mm/khugepaged: add folio dirty check after
 try_to_unmap()

This check ensures the correctness of read-only PMD folio collapse after
it is enabled for all FSes supporting PMD pagecache folios and replaces
READ_ONLY_THP_FOR_FS.

READ_ONLY_THP_FOR_FS only supports read-only fd and uses mapping->nr_thps
and inode->i_writecount to prevent any write to read-only to-be-collapsed
folios.  In upcoming commits, READ_ONLY_THP_FOR_FS will be removed and the
aforementioned mechanism will go away too.  To ensure khugepaged functions
as expected after the changes, skip if any folio is dirty after
try_to_unmap(), since a dirty folio at that point means this read-only
folio can get writes between try_to_unmap() and try_to_unmap_flush() via
cached TLB entries and khugepaged does not support writable pagecache
folio collapse yet.

Subject: [PATCH 4191/5214] mm/huge_memory: remove READ_ONLY_THP_FOR_FS from
 file_thp_enabled()

Replace it with a check on the max folio order of the file's address space
mapping, making sure PMD folio is supported.  Keep the inode
open-for-write check, since even if collapse_file() now makes sure all
to-be-collapsed folios are clean and the created PMD file THP can be
handled by FSes properly, the filemap_flush() could perform undesirable
write back.

Remove the READ_ONLY_THP_FOR_FS gate and khugepaged for file-backed
pmd-sized hugepages are enabled by the global transparent hugepage

shmem when the global control is off.

Add shmem_hpage_pmd_enabled() stub for !CONFIG_SHMEM to remove
IS_ENABLED(SHMEM) in hugepage_enabled().

Clean up hugepage_enabled() by moving anon code to anon_hpage_enabled().

Subject: [PATCH 4194/5214] mm: fs: remove filemap_nr_thps*() functions and
 their users

They are used by READ_ONLY_THP_FOR_FS to handle writes to FSes without
large folio support, so that read-only THPs created in these FSes are not
seen by the FSes when the underlying fd becomes writable.  Now read-only
PMD THPs only appear in a FS with large folio support and the supported
orders include PMD_ORDER.

READ_ONLY_THP_FOR_FS was using mapping->nr_thps, inode->i_writecount, and
smp_mb() to prevent writes to a read-only THP and collapsing writable
folios into a THP.  In collapse_file(), mapping->nr_thps is increased,
then smp_mb(), and if inode->i_writecount > 0, collapse is stopped, while
do_dentry_open() first increases inode->i_writecount, then a full memory
fence, and if mapping->nr_thps > 0, all read-only THPs are truncated.

Now this mechanism can be removed along with READ_ONLY_THP_FOR_FS code,
since a dirty folio check has been added after try_to_unmap() in
collapse_file() to prevent dirty folios from being collapsed as clean.

filemap_nr_thps*() are removed, the related field, address_space->nr_thps,
is no longer needed.  Remove it.  This shrinks struct address_space by 8
bytes on 64-bit systems which may increase the number of inodes we can
cache.

Subject: [PATCH 4197/5214] mm/truncate: use folio_split() in
 truncate_inode_partial_folio()

After READ_ONLY_THP_FOR_FS is removed, FS either supports large folio or
not.  folio_split() can be used on a FS with large folio support without
worrying about getting a THP on a FS without large folio support.

When READ_ONLY_THP_FOR_FS was present, a PMD large pagecache folio can
appear in a FS without large folio support after khugepaged or
madvise(MADV_COLLAPSE) creates it.  During truncate_inode_partial_folio(),
such a PMD large pagecache folio is split and if the FS does not support
large folio, it needs to be split to order-0 ones and could not be split
non uniformly to ones with various orders.  try_folio_split_to_order() was
added to handle this situation by checking folio_check_splittable(...,
SPLIT_TYPE_NON_UNIFORM) to detect if the large folio is created due to
READ_ONLY_THP_FOR_FS and the FS does not support large folio.  Now
READ_ONLY_THP_FOR_FS is removed, all large pagecache folios are created
with FSes supporting large folio, this function is no longer needed and
all large pagecache folios can be split non uniformly.

Change the requirement to a file system with large folio support and the

Also add tests of opening a file with read write permission and populating
folios with writes.  Reuse the XFS image from split_huge_page_test.

Subject: [PATCH 4201/5214] mm/khugepaged: enable clean pagecache folio
 collapse for writable files

collapse_file() is capable of collapsing pagecache folios from writable
files to PMD folios.  Now enable clean pagecache folio collapse in
addition to read-only pagecache folio collapse by removing the
inode_is_open_for_write() from file_thp_enabled() and only performing
filemap_flush() if the file is read-only.

This means userspace needs to explicitly flush the content of pagecache
folios before khugepaged can collapse the folios, or use
madvise(MADV_COLLAPSE), which does the flush in the retry.  The reason is
that blindly enabling dirty pagecache folio from writable files collapse
makes khugepaged flush these folios all the time.  It is undesirable to
cause system level pagecache flushes.

To properly support dirty pagecache folio collapse, filemap_flush() needs
to be avoided.  Potentially, merging associated buffer instead of dropping
it with filemap_release_folio() might be needed.

NOTE: this breaks khugepaged selftests for writable file pagecache
collapse, which is set to fail all the time.  The next commit fixes it.

Subject: [PATCH 4202/5214] selftests/mm: add writable-file collapse tests for
 khugepaged

collapse_file() now supports collapsing clean pagecache folios from
writable files, so add corresponding tests.

Note that madvise(MADV_COLLAPSE) works for dirty pagecache folios from
writable files, because collapse_single_pmd() triggers a synchronous
writeback when first attempt of collapse_file() fails.  That writeback
makes dirty folios clean and the retry of collapse_file() succeeds.

Subject: [PATCH 4203/5214] selftests/mm: hugetlb-read-hwpoison: add SIGBUS
 handler

Patch series "make MM selftests more CI friendly", v4.

There's a lot of dancing around HugeTLB settings in run_vmtests.sh.  Some
test need just a few default huge pages, some require at least 256 MB, and
some just skip lots of tests if huge pages of all supported sizes are not
available.

The goal of this set is to make tests deal with HugeTLB setup and
teardown.

There are already convenient helpers that allow easy reading and writing
of /proc and /sysfs, so adding a few APIs that will detect and update
HugeTLB settings shouldn't be a big deal.  But these nice helpers use
kselftest framework, and many of HugeTLB (and even THP) test don't, so as
a result this patchset also includes a lot of churn for conversion of
those tests to kselftest framework (patches 7-19).

The series break out:
patches 1-5:   small fixes
patch 6:       merge of hugetlb mmap tests
patch 7:       renaming of hugepage-* to hugetlb-*
patches 8-21:  mechanical conversion to kselftest framework
patches 22-28: extension of thp_settings to hugepage_settings to also include
               HugeTLB helpers
patches 29-30: add helpers for setting up SHM limits in hugetlb-shm and
               thuge-gen tests
patches 31-53: integrate the new APIs in all the tests that use HugeTLB
patches 54-55: drop HugeTLB setup from run_vmtests.sh


This patch (of 55):

Injection of a memory error with madvise() causes SIGBUS, which terminates
the hugetlb-read-hwpoison test prematurely.

Add a dummy SIGBUS handler to allow the test to continue regardless of
SIGBUS.

Subject: [PATCH 4204/5214] selftests/mm: migration: don't assume huge page is
 TWOMEG

migration tests presume that both THP and HugeTLB huge pages are 2MB.

Add dynamic detection of huge page size with read_pmd_pagesize() for THP
and with default_huge_page_size() for HugeTLB.

Subject: [PATCH 4205/5214] selftests/mm: migration: make nthreads represent
 number of working threads

Fixture setup sets self->nthreads to number of available CPUs minus 1 and
then each test creates 'self->nthreads - 1' threads or processes, so
essentially nthreads counts the worker tasks and the main task.

Make nthreads represent the number of spawned tasks to simplify
thread/process creation and teardown.

While on it, make the fixture setup skip the tests if there are not enough
CPUs or NUMA nodes instead of checking this in each test.

Subject: [PATCH 4206/5214] selftests/mm: migration: properly cleanup fork()ed
 processes

Several migration test use fork() to create worker processes.  These
processes are later killed, but nothing collects their exit status and
they remain as zombies in the system.

Add a helper function that kills the worker processes, waitpid()s for them
and verifies the exit status.

Replace the loops that call kill() for each process with a call to that
helper.

Subject: [PATCH 4208/5214] selftests/mm: merge map_hugetlb into hugepage-mmap

Both tests create a hugettlb mapping, fill it with data and verify the
data, the only difference is that one uses file-backed memory and another
one uses anonymous memory.

Merge both tests into a single file.

Subject: [PATCH 4209/5214] selftests/mm: rename hugepage-* tests to hugetlb-*

hugepage could mean both THP and HugeTLB these days.

Rename hugepage-* tests for HugeTLB to hugetlb-* to avoid confusion.

Make sure that Makefile update keeps alphabetical ordering of the
TEST_GEN_FILES entries.

Keep old binary names in .gitignore because Linus prefers it this way.

Subject: [PATCH 4215/5214] selftests/mm: khugepaged: group tests in an array

Currently khugepaged decides if a test can run using TEST() macro that
checks what mem_ops and collapse_context are set by the command line
arguments.

For better compatibility with ksefltest framework, add an array of 'struct
test_case's and redefine TEST() macro to conditionally add enabled tests
to that array.

Then execute the enabled test by looping the test_case's array.

Subject: [PATCH 4216/5214] selftests/mm: khugepaged: use kselftest framework

Convert khugepaged tests to use kselftest framework for reporting and
tracking successful and failing runs.

The conversion is mostly about replacing printf()/perror() + exit() pairs
with their ksft_ counterparts.

The nice colored success and failure indications are left intact.

Replace the progress report in collapse_compound_extreme() with a single

Subject: [PATCH 4218/5214] selftests/mm: protection_keys: use descriptive test
 names in the output

Replace the numeric test index in TAP output with the actual test function
name.

Use a structure containing function pointer and its name rather than only
the function pointer in the pkey_tests array.

Subject: [PATCH 4224/5214] selftests/mm: add atexit() and signal handlers to
 thp_settings

khugepaged registers atexit() and signal handlers that ensure that THP
settings are restored regardless of how the test exited.

Make these handlers available for all users of thp_settings.

The call to thp_save_settings() installs thp_restore_settings as the
atexit() callback and makes sure that signals that kill a process would
still call exit() and atexit() callback.

Update child process in khugepaged tests using thp_settings to use _exit()
instead of exit() to avoid altering THP settings in the middle of a test.

Remove redundant THP cleanup from folio_split_race_test.c.

From 1bdc1698e6058fc8520041fb3259dc7656deae5e Mon Sep 17 00:00:00 2001
From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>
Date: Mon, 11 May 2026 19:28:08 +0300
Subject: [PATCH 4226/5214] selftests/mm: move HugeTLB helpers to
 hugepage_settings

Move library functions that abstract HugeTLB /proc and /sysfs access from
vm_util to hugepage_settings.

This will help creating common helpers that save and restore HugeTLB and
THP settings.

Subject: [PATCH 4230/5214] selftests/mm: hugepage_settings: add APIs for
 HugeTLB setup and teardown

A lot of tests require free HugeTLB pages.  Some need just a few default
huge pages, some need a certain amount of memory available as HugeTLB, and
some just skip lots of tests if huge pages of all supported sizes are not
available.

This all resulted in a huge mess in run_vmtests.sh that sets up some huge
pages, adjusts them later and restores some of the settings if the stars
align.

Add APIs that allow saving the state of HugeTLB and setting up the desired
amount of HugeTLB pages.

Saving the state also registers atexit() callback and signal handler that
will ensure restoration of HugeTLB state.

Since many tests use both HugeTLB and THP, the atexit() callbacks and
signal handler are restoring both.

For kselftest_harness tests that run fixture setups and test in child
processes add a constructor that will save and restore settings in the
main process.

Subject: [PATCH 4231/5214] selftests/mm: move read_file(), read_num() and
 write_num() to vm_util

These are useful helpers for writing and reading sysfs and proc files.

Make them available to the tests that don't use thp_settings.

While on it make write_num() use "%lu" instead of "%ld" to match 'unsigned
long num' argument type.

Subject: [PATCH 4232/5214] selftests/mm: vm_util: add helpers to set and
 restore shm limits

hugetlb-shm and thuge-gen tests require that limits defined by
/proc/sys/kernel/{shmmax,shmall} should be higher than certain values.

Add helpers that allow setting these limits and restoring their settings
on a test exit.

They will be used later in hugetlb-shm and thuge-gen.

Subject: [PATCH 4237/5214] selftests/mm: hmm-tests: add setup of HugeTLB pages

hmm-tests skips HugeTLB tests if there are no free huge pages prepared by
a wrapper script.

Add setup of HugeTLB pages to the test and make sure that the original
settings are restored on the test exit.

Since kselftest_harness runs fixture setup and the tests in child
processes, use HUGETLB_SETUP_DEFAULT_PAGES() that defines a constructor
that runs in the main process and add verification that there are enough
free huge pages to the tests that use them.

Replace exit() calls with _exit() to avoid restoring HugeTLB settings in
the middle of test and use SIGKILL to kill a child process in
hmm_cow_in_device test to avoid interference with signal handlers in
hugepage_restore_settings().

Subject: [PATCH 4244/5214] selftests/mm: hugetlb-shm: add setup of HugeTLB
 pages

hugetlb-shm test fails if there are no free huge pages prepared by a
wrapper script and shm liimts in proc are too low.

Add setup of HugeTLB pages and shm limits to the test and make sure that
the original settings are restored on the test exit.

Subject: [PATCH 4247/5214] selftests/mm: migration: add setup of HugeTLB pages

migration skips HugeTLB tests if there are no free huge pages prepared by
a wrapper script.

Add setup of HugeTLB pages to the test and make sure that the original
settings are restored on the test exit.

Since kselftest_harness runs fixture setup and the tests in child
processes, use HUGETLB_SETUP_DEFAULT_PAGES() that defines a constructor
that runs in the main process and add verification that there are enough
free huge pages to the tests that use them.

Reset signal handlers to defaults in FIXTURE_SETUP() so that sending
SIGTERM and SIGHUP during the tests won't cause restoration of HugeTLB
settings.

Subject: [PATCH 4250/5214] selftests/mm: thuge-gen: add setup of HugeTLB pages

thuge-gen skips tests if there are no free huge pages prepared by a
wrapper script and shm liimts in proc are too low.

Replace custom detection of huge pages with the library functions and add
setup of HugeTLB pages and shm limits to the test and make sure that the
original settings are restored on the test exit.

Subject: [PATCH 4254/5214] selftests/mm: va_high_addr_switch: add setup of
 HugeTLB pages

va_high_addr_switch skips HugeTLB tests if there are no free huge pages
prepared by a wrapper script.

Add setup of HugeTLB pages to the test and make sure that the original
settings are restored on the test exit.

Subject: [PATCH 4256/5214] selftests/mm: run_vmtests.sh: free memory if
 available memory is low

Currently when running THP and HugeTLB tests, if HAVE_HUGEPAGES is set
run_test() drops caches, compacts memory and runs the test.  But if
HAVE_HUGEPAGES is not set it skips the tests entirely, even if THP tests
have nothing to do with HAVE_HUGEPAGES.

Replace the check if HAVE_HUGEPAGES is set with a check of how much memory
is available.  If there is less than 256 MB of available memory, drop
caches and run compaction and then continue to run a test regardless of
HAVE_HUGEPAGES value.

Subject: [PATCH 4258/5214] mm/khugepaged: avoid underflow in madvise_collapse
 for sub-PMD MADV_COLLAPSE

madvise_collapse() computes the THP-aligned window:

    hstart = ALIGN(start, HPAGE_PMD_SIZE); 	/* round up */
    hend = ALIGN_DOWN(end, HPAGE_PMD_SIZE);	/* round down */

The following case will cause hstart > hend, and result in underflow in
the return statement, avoid it by returning zero early when hstart > hend.
The return value is due to input is valid to madvise(), and there is
nothing to collapse.

    madvise(PMD-aligned + PAGE_SIZE, PAGE_SIZE, MADV_COLLAPSE);

In addition, kmalloc_obj(), mmgrab() and lru_add_drain_all() are
unnecessary when hstart == hend, so skip these operations by returning
early too.

Subject: [PATCH 4259/5214] selftests/mm: fix incorrect mmap() error handling
 with NULL instead of MAP_FAILED

mmap() returns MAP_FAILED, which is defined as (void *)-1, on error, not
NULL.  Several selftests incorrectly check the return value of mmap()
using !ptr or ptr == NULL, which would erroneously treat MAP_FAILED as a
valid pointer since MAP_FAILED is non-zero and non-NULL.  This can lead to
segfaults when mmap() actually fails under memory pressure.

Subject: [PATCH 4260/5214] selftests/mm: restore default nr_hugepages value
 via exit trap in charge_reserved_hugetlb.sh

Patch series "selftests/mm: fix failures and robustness improvements", v7.

Powerpc systems with a 64K base page size exposed several issues while
running mm selftests. Some tests assume specific hugetlb configurations,
use incorrect interfaces, or fail instead of skipping when the required
kernel features are not available.

This series fixes these issues and improves test robustness.


This patch (of 13):

cleanup() resets nr_hugepages to 0 on every invocation, while the test
reconfigures it again in the next iteration.  This leads to repeated
allocation and freeing of large numbers of hugepages, especially when the
original value is high.

Additionally, with set -e, failures in earlier cleanup steps (e.g., rmdir
or umount returning EBUSY while background activity is still ongoing) can
cause the script to exit before restoring the original value, leaving the
system in a modified state.

Introduce a trap on EXIT, INT, and TERM to restore the original
nr_hugepages value once at script termination.  This avoids unnecessary
allocation churn and ensures the original value is reliably restored on
all exit paths.

Subject: [PATCH 4261/5214] selftests/mm: fix hugetlb pathname construction in
 charge_reserved_hugetlb.sh

The charge_reserved_hugetlb.sh script assumes hugetlb cgroup memory
interface file names use the "<size>MB" format
(e.g. hugetlb.1024MB.current).
This assumption breaks on systems with larger huge pages such as 1GB,
where the kernel exposes normalized units:
    hugetlb.1GB.current
    hugetlb.1GB.max
    hugetlb.1GB.rsvd.max
    ...

As a result, the script attempts to access files like
hugetlb.1024MB.current, which do not exist when the kernel reports the
size in GB.

Normalize the huge page size and construct the pathname using the
appropriate unit (MB or GB), matching the hugetlb controller naming.

Subject: [PATCH 4262/5214] selftests/mm: restore default nr_hugepages value
 via exit trap in hugetlb_reparenting_test.sh

The test modifies nr_hugepages during execution and restores it from
cleanup() and again reconfigure it setup, which is invoked multiple times
across test flow.  This can lead to repeated allocation/freeing of
hugepages.

With set -e, failures in cleanup (e.g., rmdir/umount) can also cause early
exit before restoring the original value at the end.

Move restoration of the original nr_hugepages value to a trap handler
registered for EXIT, INT, and TERM signals so it is always restored on all
exit paths.  This also avoids unnecessary allocation churn across repeated
cleanup/setup cycles.

Subject: [PATCH 4263/5214] selftests/mm: fix hugetlb pathname construction in
 hugetlb_reparenting_test.sh

The hugetlb_reparenting_test.sh script constructs hugetlb cgroup memory
interface file names based on the configured huge page size.  The script
formats the size only in MB units, which causes mismatches on systems
using larger huge pages where the kernel exposes normalized units (e.g.
"1GB" instead of "1024MB").

As a result, the test fails to locate the corresponding cgroup files when
1GB huge pages are configured.

Update the script to detect the huge page size and select the appropriate
unit (MB or GB) so that the constructed paths match the kernel's hugetlb
controller naming.

Also print an explicit "Fail" message when a test failure occurs to

Subject: [PATCH 4264/5214] selftests/mm: fix cgroup task placement and drop
 memory.current checks in hugetlb_reparenting_test.sh

The test currently moves the calling shell ($$) into the target cgroup
before executing write_to_hugetlbfs.  This results in the shell and any
intermediate allocations being charged to the cgroup, introducing noise
and nondeterminism in accounting.  It also requires moving the shell back
to the root cgroup after execution.

Spawn a helper process that joins the target cgroup and exec()'s
write_to_hugetlbfs.  This ensures that only the workload is accounted to
the cgroup and avoids unintended charging from the shell.

The test currently validates both hugetlb usage and memory.current.
However, memory.current includes internal memcg allocations and per-CPU
batched accounting (MEMCG_CHARGE_BATCH), which are not synchronized and
can vary across systems, leading to non-deterministic results.

Since hugetlb memory is accounted via hugetlb.<size>.current,
memory.current is not a reliable indicator here.  Drop memory.current
checks and rely only on hugetlb controller statistics for stable and
accurate validation.

Subject: [PATCH 4265/5214] selftests/mm: size tmpfs according to PMD page size
 in split_huge_page_test

The split_file_backed_thp() test mounts a tmpfs with a fixed size of "4m".
This works on systems with smaller PMD page sizes, but fails on
configurations where the PMD huge page size is larger (e.g.  16MB).

On such systems, the fixed 4MB tmpfs is insufficient to allocate even a
single PMD-sized THP, causing the test to fail.

Fix this by sizing the tmpfs dynamically based on the runtime
pmd_pagesize, allocating space for two PMD-sized pages.

Subject: [PATCH 4266/5214] selftests/mm: free dynamically allocated PMD-sized
 buffers in split_huge_page_test

Dynamically allocated buffers of PMD size for file-backed THP operations
(file_buf1 and file_buf2) were not freed on the success path and some
failure paths.  Since the function is called repeatedly in a loop for each
split order, this can cause significant memory leaks.

On architectures with large PMD sizes, repeated leaks could exhaust system
memory and trigger the OOM killer during test execution.

Ensure all allocated buffers are freed to maintain stable repeated test
runs.

Subject: [PATCH 4267/5214] selftest/mm: register existing mapping with
 userfaultfd in hugetlb-mremap

Previously, register_region_with_uffd() created a new anonymous mapping
and overwrote the address supplied by the caller before registering the
range with userfaultfd.

As a result, userfaultfd was applied to an unrelated anonymous mapping
instead of the hugetlb region used by the test.

Remove the extra mmap() and register the caller-provided address range
directly using UFFDIO_REGISTER_MODE_MISSING, so that faults are generated
for the hugetlb mapping used by the test.

This ensures userfaultfd operates on the actual hugetlb test region and
validates the expected fault handling.

Subject: [PATCH 4268/5214] selftests/mm: ensure destination is hugetlb-backed
 in hugetlb-mremap

The hugetlb-mremap selftest reserves the destination address using a
anonymous base-page mapping before calling mremap() with MREMAP_FIXED,
while the source region is hugetlb-backed.

When remapping a hugetlb mapping into a base-page VMA may fail with:

    mremap: Device or resource busy

This is observed on powerpc hash MMU systems where slice constraints and
page size incompatibilities prevent the remap.

Ensure the destination region is created using MAP_HUGETLB so that both
source and destination VMAs are hugetlb-backed and compatible.

Update the FLAGS macro to include MAP_HUGETLB | MAP_SHARED so that both
mappings are hugetlb-backed and compatible.  Also use the macro for the
mmap() calls to avoid repeating the flag combination.

This ensures the test reliably exercises hugetlb mremap instead of failing
due to VMA type mismatch.

Subject: [PATCH 4269/5214] selftests/mm: skip uffd-wp-mremap if UFFD
 write-protect is unsupported

The uffd-wp-mremap test requires the UFFD_FEATURE_PAGEFAULT_FLAG_WP
capability.  On systems where userfaultfd write-protect is not supported,
uffd_register() fails and the test reports failures.

Check for the required feature at startup and skip the test when the
UFFD_FEATURE_PAGEFAULT_FLAG_WP capability is not present, preventing false
failures on unsupported configurations.

Subject: [PATCH 4270/5214] selftests/mm: skip uffd-stress test when
 nr_pages_per_cpu is zero

uffd-stress currently fails when the computed nr_pages_per_cpu evaluates
to zero:

nr_pages_per_cpu = bytes / page_size / nr_parallel

This can occur on systems with large hugepage sizes (e.g.  1GB) and a high
number of CPUs, where the total allocated memory is sufficient overall but
not enough to provide at least one page per cpu.

In such cases, the failure is due to insufficient test resources rather
than incorrect kernel behaviour.  Update the test to treat this condition
as a test skip instead of reporting an error.

Subject: [PATCH 4271/5214] selftests/mm: move hwpoison setup into run_test()
 and silence modprobe output for memory-failure category

run_vmtests.sh contains special handling to ensure the hwpoison_inject
module is available for the memory-failure tests.  This logic was
implemented outside of run_test(), making the setup category-specific but
managed globally.

Move the hwpoison_inject handling into run_test() and restrict it
to the memory-failure category so that:
1. the module is checked and loaded only when memory-failure tests run,
2. the test is skipped if the module or the debugfs interface
(/sys/kernel/debug/hwpoison/) is not available.
3. the module is unloaded after the test if it was loaded by the script.

This localizes category-specific setup and makes the test flow
consistent with other per-category preparations.

While updating this logic, fix the module availability check.
The script previously used:

        modprobe -R hwpoison_inject

The -R option prints the resolved module name to stdout, causing every
run to print:

        hwpoison_inject

in the test output, even when no action is required, introducing
unnecessary noise.

Replace this with:

        modprobe -n hwpoison_inject

which verifies that the module is loadable without producing output,
keeping the selftest logs clean and consistent.

Also, ensure that skipped tests do not override a previously recorded
failure.  A skipped test currently sets exitcode to ksft_skip even if a
prior test has failed, which can mask failures in the final exit status.
Update the logic to only set exitcode to ksft_skip when no failure has
been recorded.

Subject: [PATCH 4274/5214] mm: merge writeout into pageout

writeout is only called from pageout, and a straight flow at the end, so
merge the two functions.

Subject: [PATCH 4275/5214] selftests: mm: fix and speedup "droppable" test

The droppable test currently relies on creating memory pressure in a child
process to trigger dropping the droppable pages.

That not only takes a long time on some machines (allocating and filling
all that memory), on large machines this will not work as we hardcode the
area size to 134217728 bytes.

...  further, we rely on timeouts to detect that memory was not dropped,
which is really suboptimal.

Instead, let's just use MADV_PAGEOUT on a 2 MiB region.  MADV_PAGEOUT
works with droppable memory even without swap.

There is the low chance of MADV_PAGEOUT failing to drop a page because of
speculative references.  We'll wait 1s and retry 10 times to rule that
unlikely case out as best as we can.

On a machine without swap:

	$ ./droppable
	TAP version 13
	1..1
	ok 1 madvise(MADV_PAGEOUT) behavior
	# Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0

Subject: [PATCH 4276/5214] mm/shrinker: do not hold RCU lock in
 shrinker_debugfs_count_show()

Reading the debugfs "count" file of a memcg-aware shrinker can sleep
inside an RCU read-side critical section:

  BUG: sleeping function called from invalid context at kernel/cgroup/rstat.c:421
  RCU nest depth: 1, expected: 0
   css_rstat_flush
   mem_cgroup_flush_stats
   zswap_shrinker_count
   shrinker_debugfs_count_show

shrinker_debugfs_count_show() invokes the ->count_objects() callback under
rcu_read_lock().  The zswap callback flushes memcg stats via
css_rstat_flush(), which may sleep, so it must not run under RCU.

The RCU lock is not needed here.  mem_cgroup_iter() takes RCU internally
and returns a memcg holding a css reference (dropped on the next iteration
or by mem_cgroup_iter_break()), so the memcg stays alive without it.  The
shrinker is kept alive by the open debugfs file: shrinker_free() removes
the debugfs entries via debugfs_remove_recursive(), which waits for
in-flight readers to drain, before call_rcu(..., shrinker_free_rcu_cb).
The sibling "scan" handler already invokes the sleeping ->scan_objects()
callback with no RCU section.

Drop the rcu_read_lock()/rcu_read_unlock().

Subject: [PATCH 4277/5214] mm: page_isolation: avoid unsafe folio reads while
 scanning compound pages

page_is_unmovable() can inspect compound pages without holding a folio
reference or any lock.  The folio can therefore be freed, split or reused
while the scanner is still looking at it.

The existing HugeTLB handling already avoids folio_hstate() for this
reason, but it still derives the hstate from folio_size() and later
derives the scan step from folio_nr_pages() and folio_page_idx().  These
helpers rely on the folio still being a valid folio head.  If the folio
changed concurrently, the scanner can read inconsistent folio metadata and
compute a wrong step.  In the worst case, folio_nr_pages() can return 1
for what used to be a tail page and the subtraction from folio_page_idx()
can underflow.

There is a similar issue for non-Hugetlb compound pages: folio_test_lru()
expects a valid folio.  If the previously observed head page has been
reused as a tail page of another compound page, the folio flag checks can
trigger VM_BUG_ON_PGFLAGS().

Read the compound order once with compound_order(), reject obviously bogus
orders, and derive the hstate and scan step from that order instead of
querying folio size information again.  Also use PageLRU(page), which is
safe for the page being scanned, instead of folio_test_lru() on a
potentially stale folio pointer.

Treat an unknown HugeTLB hstate as unmovable so the scanner does not try
to skip over an unstable HugeTLB folio.

Subject: [PATCH 4278/5214] mm/damon/core: always put unsuccessfully committed
 target pids

damon_commit_target() puts and gets the destination and the source target
pids.  It puts the destination target pid because it will be overwritten
by the source target pid.  It gets the source pid because the caller is
supposed to eventually put the pids.  In more detail, the caller will call
damon_destroy_ctx() after damon_commit_ctx() to destroy the entire source
context.  And in this case, [f]vaddr operation set's cleanup_target()
callback will put the pids.

The commit operation is made at the context level.  The operation can fail
in multiple places including in the middle and after the targets commit
operations.  For any such failures, immediately the error is returned to
the damon_commit_ctx() caller.  If some or all of the source target pids
were committed to the destination during the unsuccessful context commit
attempt, those pids should be put twice.

The source context will do the put operations using the above explained
routine.  However, let's suppose the destination context was not
originally using [f]vaddr operation set and the commit failed before the
ops of the source context is committed.  The destination does not have the
cleanup_target() ops callback, so it cannot put the pids via the
damon_destroy_ctx().

As a result, the pids are leaked.  The issue in the real world would be
not very common.  The commit feature is for changing parameters of running
DAMON context while inheriting internal status like the monitoring
results.  The monitoring results of a physical address range ain't have
things that are beneficial to be inherited to a virtual address ranges
monitoring.  So the problem-causing DAMON control would be not very common
in the real world.  That said, it is a supported feature.  And
damon_commit_target() failure due to memory allocation is relatively
realistic [1] if there are a huge number of target regions.

Fix by putting the pids in the commit operation in case of the failures.

The issue was discovered [2] by Sashiko.

That validation is itself unsafe for negative or out-of-range CPU numbers.
For example, test_push_cpu=-1 is converted to a very large unsigned CPU
number before cpu_active() reaches cpumask_test_cpu(), which trips the
cpumask range check with CONFIG_DEBUG_PER_CPU_MAPS enabled.

Reject CPU values outside [0, nr_cpu_ids) before asking whether the CPU is
active.

Subject: [PATCH 4280/5214] mm/gup_test: reject wrapped user ranges

gup_test accepts an address and size from the debugfs ioctl and repeatedly
compares against addr + size.  If that addition wraps, the loop can be
skipped and the ioctl returns success with size rewritten to zero.

Compute the end address once with overflow checking and use that checked
end for the loop bounds.

Subject: [PATCH 4281/5214] selftests/mm: allow PUD-level entries in compound
 testcase of hmm tests

Patch series "selftests/mm: assorted fixes for hmm-tests", v3.

This series fixes a few issues in hmm-tests that show up when page-size
and huge-page configuration differ from the hardcoded assumptions the
tests were written for (PMD/THP sizing, default hugepage size, and related
cases).

It also includes a fix to exclusive_cow: the test ignored the return value
of fork(), so both parent and child ran the same teardown path.


This patch (of 3):

The HMM compound testcase currently assumes only PMD-level mappings and
fails on systems where default_hugepagesz=1G is set, because the region is
then reported by the device at PUD level.

Determine the mapping level (PMD or PUD) the device reports for the first
page of the range and require every page to match that level exactly via
ASSERT_EQ().  This accepts PUD-level mappings while preserving the
expected/observed protection values printed on failure, and rejects a
fragmented mapping that mixes PMD- and PUD-level entries within the same
range (which a per-page OR check would have let pass).

Subject: [PATCH 4282/5214] selftests/mm: remove hardcoded THP sizing
 assumptions in hmm tests

migrate_partial_unmap_fault() and migrate_remap_fault() use hardcoded
offsets based on a 2MB PMD size.  Similarly, benchmark_thp_migration()
assumes a fixed 2MB THP size when generating test buffer sizes.

Derive offsets and test sizes from the runtime PMD page size returned by
read_pmd_pagesize().  If unavailable, fall back to TWOMEG.  This allows
the tests to adapt correctly on systems where PMD-sized THP differs from
2MB.  Also replace the fixed 1MB unmap size with a PMD-relative value
derived from the runtime PMD size.

On systems with larger PMD sizes, computed test buffer sizes can exceed
INT_MAX.  Skip such test cases to avoid overflow.

Subject: [PATCH 4283/5214] selftests/mm: fix exclusive_cow test fork()
 handling

The test ignores the return value of fork(), so both the parent and the
(newly created) child run the COW verification loops and then call
hmm_buffer_free() before returning into the kselftest harness, which
_exit()s each side.  This duplicated teardown sequence has been observed
to manifest as a SIGSEGV in the test child, e.g.:

  hmm-tests[360141]: segfault (11) at 0 nip 10006964 lr 1000ac3c code 1
  in hmm-tests[6964,10000000+30000]

Fix this by adopting the same fork()-then-wait pattern already used by the
nearby anon_write_child / anon_write_child_shared tests in this file: the
child performs the COW verification and then _exit(0)s so it does not run
the test teardown, while the parent independently verifies COW, waits for
the child, and only then frees the buffer.

Subject: [PATCH 4285/5214] mm/vmscan: pass NULL to trace vmscan node reclaim

The tracepoint for node relcaims takes a `struct mem_cgroup *`
as the third argument, so pass NULL instead of 0 to fix warning
about using an integer as a pointer.

Fixes the following warnings:

mm/vmscan.c:6753:66: warning: Using plain integer as NULL pointer
mm/vmscan.c:6757:58: warning: Using plain integer as NULL pointer

Subject: [PATCH 4286/5214] Revert "mm: limit filemap_fault readahead to VMA
 boundaries"

This reverts commit 7b32f64bc512b40b268776c5ac4d354b325b3197.

This patch caused a significant performance regression, so revert it, and
we can determine whether the approach is sensible or not moving forwards,
and if so how to avoid this.

There was a merge conflict with commit de97ae6222c1 ("mm/readahead: no
PG_readahead on EOF"), care was taken to ensure that the revert retained
the behaviour of this patch and cleanly reverts commit 7b32f64bc512 ("mm:
limit filemap_fault readahead to VMA boundaries") only.

cpuhp_invoke_callback() unwinds earlier callbacks for the same
hotplug state when one instance fails. The rollback path currently
reuses ret, so a successful rollback can hide the original error and
make the failed transition look successful.

Keep the rollback result separate from the original error.

Subject: [PATCH 4289/5214] lib: Add stale 'raid6' directory to .gitignore file

I keep having to do this, because people think they can just move
directories around and move the gitignore files around with them.

You really can't do that - the old generated files stay around for
others, and still need to be ignored in the old location.

So when moving gitignore entries around because you moved the files (or
when moving a whole gitignore file around because the directory it was
in moved), the old gitignore situation needs to be dealt with.

Yes, those files may have moved in *your* tree when you moved the
directory.  And yes, new repositories will never even have seen them.
But all those other developers that see the result of your move still
likely have a working tree with the old state, and the files that were
hidden from git by an old gitignore file do not suddenly become
relevant.

prestera_port_sfp_bind() returns err after walking the ports node. If no

Initialize err to 0 because absence of a matching optional port device
tree node is not an error. In that case no phylink is created and port
creation should continue with port->phy_link left NULL. Errors from
malformed matched nodes and phylink_create() still propagate.

Subject: [PATCH 4291/5214] tipc: fix use-after-free of the discoverer in
 tipc_disc_rcv()

bearer_disable() frees b->disc with tipc_disc_delete()'s plain kfree(),
but tipc_disc_rcv() still dereferences b->disc in RX softirq under
rcu_read_lock() (tipc_udp_recv -> tipc_rcv -> tipc_disc_rcv).

L2 bearers are safe thanks to the synchronize_net() in
tipc_disable_l2_media(), but the UDP bearer defers that call to the
cleanup_bearer() workqueue, so the discoverer is freed with no grace
period:

 BUG: KASAN: slab-use-after-free in tipc_disc_rcv (net/tipc/discover.c:149)
 Read of size 8 at addr ffff88802348b728 by task poc_tipc/184

  tipc_rcv (net/tipc/node.c:2126)

  udp_rcv (net/ipv4/udp.c:2643)
  ip_local_deliver_finish (net/ipv4/ip_input.c:241)
 </IRQ>
 Freed by task 181:
  kfree (mm/slub.c:6565)
  bearer_disable (net/tipc/bearer.c:418)
  tipc_nl_bearer_disable (net/tipc/bearer.c:1001)

The bearer is freed with kfree_rcu(); free the discoverer the same way.
Add an rcu_head to struct tipc_discoverer and free it and its skb from an
RCU callback.

Because the RCU callback (tipc_disc_free_rcu) lives in module text, a
call_rcu() that is still pending when the tipc module is unloaded would
invoke a freed function. Add an rcu_barrier() to tipc_exit() after the
bearer subsystem has been torn down, so all pending discoverer callbacks
have run before the module text goes away.

Reachable from an unprivileged user namespace: the TIPCv2 genl family is
netnsok and its bearer commands have no GENL_ADMIN_PERM. Needs CONFIG_TIPC
and CONFIG_TIPC_MEDIA_UDP.

Subject: [PATCH 4292/5214] net: dst_metadata: fix false-positive memcpy
 overflow in tun_dst_unclone

kmalloc_flex() in metadata_dst_alloc() sets __counted_by for the
structure to the options_len, which is then initialized to zero.
Later, we're initializing the structure by copying the tunnel info
together with the options, and this triggers a warning for a potential
memcpy overflow, since the compiler estimates that the options can't
fit into the structure, even though the memory for them is actually
allocated.

 memcpy: detected buffer overflow: 104 byte write of buffer size 96
 WARNING: CPU: X PID: Y at lib/string_helpers.c:1036 __fortify_report
  skb_tunnel_info_unclone+0x179/0x190
  geneve_xmit+0x7fe/0xe00

The issue is triggered when built with clang and source fortification.

Fix that by doing the copy in two stages: first - the main data with
the options_len, then the options.  This way the correct length should
be known at the time of the copy.

It would be better if the options_len never changed after allocation,
but the allocation code is a little separate from the initialization
and it would be awkward and potentially dangerous to return a struct
with options_len set to a non-zero value from the metadata_dst_alloc().

Another option would be to use ip_tunnel_info_opts_set(), but it is
doing too many unnecessary operations for the use case here.

Subject: [PATCH 4293/5214] net: ethernet: mtk_ppe: Fix rhashtable leak in
 mtk_ppe_init error paths

In mtk_ppe_init(), when accounting is enabled, the error paths for
dmam_alloc_coherent(mib) and devm_kzalloc(acct) failures return NULL
directly, bypassing the err_free_l2_flows label that destroys the
rhashtable initialized earlier.

While this leak only occurs during probe (not runtime) and the leaked
memory is minimal (an empty rhash table), fixing it ensures proper
error path cleanup consistency.

Fix by changing the two return NULL statements to goto err_free_l2_flows.

Subject: [PATCH 4299/5214] net/sched: act_ct: fix nf_connlabels leak on two
 error paths

tcf_ct_fill_params() calls nf_connlabels_get() (setting put_labels) when
TCA_CT_LABELS is present, but two later error sites use a bare return
instead of "goto err", skipping the err: nf_connlabels_put() cleanup.
They also precede the "p->put_labels = put_labels" assignment, so the
tcf_ct_params_free() fallback does not release the count either. Each
failed RTM_NEWACTION on these paths leaks one nf_connlabels reference:
net->ct.labels_used is incremented and never released. The action is
reachable with CAP_NET_ADMIN over the netns, i.e. from an unprivileged
user namespace on default-userns kernels.

Impact: an unprivileged user with CAP_NET_ADMIN over a network namespace
(e.g. via user namespaces) leaks one nf_connlabels reference per failed
RTM_NEWACTION on the two error paths; net->ct.labels_used is never
released.

The err: label is safe to reach from both sites: p->tmpl is still NULL
there (kzalloc'd, not yet assigned) and nf_ct_put(NULL) is a no-op, so
no inline release is needed.

(the default for unclassified traffic), (0u - 1u) wraps to UINT_MAX,
and UINT_MAX % 8 = 7, routing default best-effort packets to the
highest-priority QoS queue. This causes QoS inversion where the
majority of traffic on a PON gateway starves actual high-priority
flows (VoIP, gaming, etc.).

The "- 1" offset was a leftover from the ETS offload implementation
that has since been removed. The correct mapping is a direct modulo:

  queue = skb->priority % AIROHA_NUM_QOS_QUEUES;

This maps priority 0 → queue 0 (lowest), priority 7 → queue 7
(highest), with higher priorities wrapping around. This is the
standard Linux sk_prio → HW queue mapping used by other drivers.

Subject: [PATCH 4301/5214] net: sit: require CAP_NET_ADMIN in the device netns
 for changelink

ipip6_changelink() operates on at most two netns, dev_net(dev) and the
tunnel link netns t->net. They differ once the device is created in or
moved to a netns other than the one the request runs in. The rtnl
changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a
caller privileged there but not in t->net can rewrite a tunnel that
lives in t->net.

Gate ipip6_changelink() on rtnl_dev_link_net_capable() at its top,
before any attribute is parsed. sit was the one tunnel type not covered
by the recent series that added this check to the other changelink()
handlers.

Subject: [PATCH 4302/5214] ipv6: ndisc: fix NULL deref in
 accept_untracked_na()

accept_untracked_na() re-fetches the inet6_dev with __in6_dev_get(dev)
and dereferences idev->cnf.accept_untracked_na without a NULL check,
even though its only caller ndisc_recv_na() already fetched and
NULL-checked idev for the same device.

Both reads of dev->ip6_ptr run in the same RCU read-side critical
section, but a concurrent addrconf_ifdown() can clear dev->ip6_ptr
between them: lowering the MTU below IPV6_MIN_MTU calls addrconf_ifdown()
without the synchronize_net() that orders the unregister path, so the
re-fetch returns NULL and oopses:

 BUG: KASAN: null-ptr-deref in ndisc_recv_na (net/ipv6/ndisc.c:974)
 Read of size 4 at addr 0000000000000364
 Call Trace:

  </IRQ>

It is reachable by an unprivileged user via a network namespace.

Pass the caller's already validated idev instead of re-fetching it; the
idev stays alive for the whole RCU critical section, so it is safe even
after dev->ip6_ptr has been cleared.

Subject: [PATCH 4303/5214] net/sched: dualpi2: fix GSO backlog accounting

When DualPI2 splits a GSO skb into N segments, it propagates N
additional packets to its parent before returning NET_XMIT_SUCCESS.
The parent then accounts for the original skb once more, leaving its
qlen one larger than the number of packets actually queued.

With QFQ as the parent, after all real packets are dequeued, QFQ still
has a non-zero qlen while its in-service aggregate has no active
classes. qfq_choose_next_agg() returns NULL and qfq_dequeue() passes
the result to qfq_peek_skb(), causing a NULL pointer dereference.

Follow the same pattern used by tbf_segment() and taprio: count only
successfully queued segments, propagate the difference between the
original skb and those segments, and return NET_XMIT_SUCCESS whenever
at least one segment was queued.

Subject: [PATCH 4304/5214] selftests/tc-testing: Add DualPI2 GSO backlog
 accounting test

Add a regression test for DualPI2 GSO backlog accounting when it is
used as a child qdisc of QFQ.

The test sends one UDP GSO datagram through a QFQ class with DualPI2 as
the leaf qdisc. DualPI2 splits the skb into two segments. After the
traffic drains, both QFQ and DualPI2 must report zero backlog and zero
qlen.

On kernels with the broken accounting, QFQ can keep a stale non-zero
qlen after all real packets have been dequeued.

Subject: [PATCH 4305/5214] ipv4: account for fraggap on the paged allocation
 path

In __ip_append_data(), when the paged-allocation branch is taken,
alloclen and pagedlen are computed as

	alloclen = fragheaderlen + transhdrlen;
	pagedlen = datalen - transhdrlen;

datalen already includes fraggap, but the fraggap bytes carried over
from the previous skb are copied into the new skb's linear area at
offset transhdrlen by the subsequent skb_copy_and_csum_bits(). The
linear area is therefore undersized by fraggap bytes while pagedlen is
overstated by the same amount.

The non-paged branch sets alloclen to fraglen, which already accounts
for fraggap because datalen does. Bring the paged branch in line by
adding fraggap to alloclen and subtracting it from pagedlen.

After this adjustment, copy no longer collapses to -fraggap on the
paged path, so remove the stale comment describing that old arithmetic.

Subject: [PATCH 4306/5214] ipv6: account for fraggap on the paged allocation
 path

In __ip6_append_data(), when the paged-allocation branch is taken
(MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are
computed as

	alloclen = fragheaderlen + transhdrlen;
	pagedlen = datalen - transhdrlen;

datalen already includes fraggap (datalen = length + fraggap). When
fraggap is non-zero, this is not the first skb and transhdrlen is zero.
The fraggap bytes carried over from the previous skb are copied just past
the fragment headers in the new skb's linear area. The linear area is
therefore undersized by fraggap bytes while pagedlen is overstated by the
same amount, and the copy writes past skb->end into the trailing
skb_shared_info.

An unprivileged user can trigger this via a UDPv6 socket using
MSG_MORE together with MSG_SPLICE_PAGES.

The bad accounting was introduced by commit 773ba4fe9104 ("ipv6:
avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix
__ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative
copy value caused -EINVAL to be returned. That later commit allowed
MSG_SPLICE_PAGES to proceed in this case, making the corruption
triggerable.

The non-paged branch sets alloclen to fraglen, which already accounts
for fraggap because datalen does. Bring the paged branch in line by
adding fraggap to alloclen and subtracting it from pagedlen.

After this adjustment, copy no longer collapses to -fraggap on the
paged path, so remove the stale comment describing that old arithmetic.
Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES
case, remove the MSG_SPLICE_PAGES exception from the negative copy check.

Subject: [PATCH 4307/5214] ipv6: ioam: fix type confusion of dst_entry

IOAM uses a dummy dst_entry(null_dst) to mark that the destination should
not be changed after the transformation. This dst is stored in the IOAM lwt
state and may be passed to dst_cache_set_ip6().

However, the IPv6 dst cache path eventually calls rt6_get_cookie(), which
treats the dst_entry as part of a struct rt6_info. Since the null_dst was
embedded directly as a struct dst_entry in struct ioam6_lwt, this resulted
in an invalid cast and rt6_get_cookie() reading fields from the wrong
object.

In practice, the wrong cookie is not used while dst->obsolete is zero, but
rt6_get_cookie() may also access per-cpu value when rt->sernum is
zero. In this case, rt->sernum aliases ioam6_lwt::cache::reset_ts, which
can become zero, making this a potential invalid pointer access.

Fix this by embedding a full struct rt6_info for the dummy IPv6 route and
passing its dst member to the dst APIs.

Subject: [PATCH 4308/5214] dpaa2-switch: do not accept VLAN uppers while
 bridged

The dpaa2-switch driver does not support VLAN uppers while its ports are
bridged. This scenario tried to be prevented by rejecting a bridge join
while VLAN uppers exist but the reverse order was still possible.

This patches adds a check so that the dpaa2-switch also does not accept
VLAN uppers while bridged.

Subject: [PATCH 4309/5214] erofs: add sparse support to pcluster layout

Although zeros can be compressed transparently on EROFS using fixed-size
output compression so that it is never prioritized in the Android use
cases, indicating entire pclusters as holes is still useful to preserve
holes in the sparse datasets; otherwise overlayfs will allocate more
space when copying up, and SEEK_HOLE won't report any hole.

This patch introduces two ways to mark a pcluster as a hole:

 - A new Z_EROFS_LI_HOLE compatible flag (bit 14) in the HEAD lcluster
   advise field for non-compact (full) indexes;

 - A 0-block CBLKCNT value on the first NONHEAD lcluster.

The hole tag is preferred for maximum compatibility since pre-existing
kernels that do not understand Z_EROFS_LI_HOLE will decompress at the
stored blkaddr (the same blkaddr will be shared among all sparse
pclusters).  Only the 0-block CBLKCNT approach also works for compact
indexes, but it is limited to big pclusters and new kernels.

Subject: [PATCH 4312/5214] rtc: renesas-rtca3: Fix PIE clear polling condition
 in alarm setup error path

In rtca3_set_alarm(), the setup_failed path attempts to disable the
Periodic Interrupt Enable (PIE) bit and wait until it is cleared.
However, the polling condition passed to readb_poll_timeout_atomic()
uses an incorrect expression:

    !(tmp & ~RTCA3_RCR1_PIE)

As ~RTCA3_RCR1_PIE evaluates to a mask of all bits except PIE, the
condition effectively waits for all non-PIE bits to become zero, which
is unrelated to the intended operation and is unlikely to ever be true.
This causes the poll to time out unnecessarily.

Fix the condition to check for the PIE bit itself being cleared:

    !(tmp & RTCA3_RCR1_PIE)

This correctly waits until PIE is deasserted after being cleared.

Subject: [PATCH 4313/5214] rtc: renesas-rtca3: Check RADJ poll result during
 initial setup

In rtca3_initial_setup(), the driver clears the RTCA3_RADJ register and
waits for it to reach zero using readb_poll_timeout(). Check the return
value of readb_poll_timeout() and propagate the error if the poll fails.

Subject: [PATCH 4317/5214] rtc: abx80x: fix the RTC_VL_CLR clearing all status
 flags

The RTC_VL_CLR ioctl intends to clear only the battery low flag (BLF),
however the current implementation writes 0 to the status register,
clearing all status bits.

Fix this by writing back the masked status value so that only BLF is
cleared, preserving other status flags.

Subject: [PATCH 4318/5214] rtc: mpfs: fix counter upload completion condition

The condition that needs to be checked for upload completion is the
UPLOAD bit in the completion register going low. The original iterations
of this driver used a do-while and this was converted to a
read_poll_timeout() during upstreaming without the condition being
inverted as it should have been.

I suspect that this went unnoticed until now because a) the first read
was done when the bit was still set, immediately completing the
read_poll_timeout() and b) because the RTC doesn't hold time when power
is removed from the SoC reducing its utility (I for one keep it
disabled). If my first suspicion was true when the driver was
upstreamed, it's not true any longer though, hence the detection of the
problem.

Subject: [PATCH 4319/5214] rtc: ds1307: handle oscillator stop flag for
 ds1337/ds1339/ds3231

Prior to commit 48458654659c ("rtc: ds1307: remove clear of oscillator
stop flag (OSF) in probe"), the oscillator stop flag (OSF) bit was
checked during device probe for the ds1337, ds1339, ds1341, and ds3231
chips; if it was set, it would be cleared and a warning would be logged
saying "SET TIME!". Since that commit, the OSF bit is no longer cleared,
but the warning is still printed.

Directly following that commit, there was no way to get rid of this
warning because nothing cleared the OSF bit on these chips.

The commit associated with the previous commit, 523923cfd5d6 ("rtc:
ds1307: handle oscillator stop flag (OSF) for ds1341"), made proper use
of the OSF when getting and setting the time in the RTC. However, the
other RTC variants ds1337, ds1339 and ds3231 didn't have a corresponding
change made.

Given that the OSF bit is no longer cleared at probe time when it is
set, the remaining three chips should have the same handling as the
ds1341 chip has for the OSF bit.

Fix the issue on the ds1337, ds1339 and ds3231 chips by applying the
same logic as the ds1341 has to these chips.

Note that any devices brought up between the first referenced commit and
this one may begin mistrusting the time reported by the RTC until it is
set again, if the bit was never explicitly cleared.

Note that only the ds1339 was tested with this change, but the
datasheets for the other chips contain essentially identical
descriptions of the OSF bit so the same change should work.

Subject: [PATCH 4320/5214] rtc: Use named initializers for arrays of
 i2c_device_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify usage of whitespace and commas.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The two drivers explicitly set the .driver_data member of struct
platform_device_id to zero without relying on that value. Drop this
unused assignments.

While touching these array unify spacing, usage of commas and use named
initializers for .name.

Content-Transfer-Encoding: 8bit

Instead of hiding the rtc ops for the only supported device behind an
abstraction for multi-device support, hardcode the used ops which gets rid
of the need to call platform_get_device_id and two casts.

Named initializers are better readable and more robust to changes of the

While touching these arrays unify spacing and usage of commas.

Subject: [PATCH 4324/5214] bpf: Fix stack slot index in nospec checks

check_stack_write_fixed_off() computes the byte slot for a fixed-offset
stack write as -off - 1, and records each written byte in slot_type[] with
(slot - i) % BPF_REG_SIZE.

The Spectre v4 sanitization pre-check uses slot_type[i] instead. For a
4-byte write at fp-8 after the lower half of fp-8 has been zeroed, the
pre-check scans bytes 0..3 and sees STACK_ZERO while the actual write updates
bytes 7..4. That can leave the second half-slot write without nospec_result
even though the bytes being overwritten still require sanitization.

Use the same slot index in the sanitization pre-check that the write path uses
when updating slot_type[].

Add a verifier test for the fixed-offset stack write case where two 4-byte

The test runs through the unprivileged loader lane and expects both
half-slot writes to emit nospec in the translated program.

Subject: [PATCH 4326/5214] bpf: Fix partial copy of non-linear test_run output

For non-linear test_run output, bpf_test_finish() derives the linear
data copy length from copy_size - frag_size. This only matches the
linear data length when copy_size is the full packet size.

When userspace provides a short data_out buffer, copy_size is clamped to
that buffer size. If copy_size is smaller than frag_size, the computed
length becomes negative and bpf_test_finish() returns -ENOSPC before
copying the packet prefix or updating data_size_out.

Compute the linear data length from the packet layout instead, and clamp
the linear copy length to copy_size. This preserves the expected
partial-copy semantics: return -ENOSPC, copy the packet prefix that fits
in data_out, and report the full packet length through data_size_out.

Subject: [PATCH 4327/5214] bpf: Fix build_id caching in
 stack_map_get_build_id_offset()

This patch is a follow up to recent implementation of
stack_map_get_build_id_offset_sleepable() [1].

stack_map_get_build_id_offset() and its sleepable variant each cached
only the last successfully resolved VMA, with separate bookkeeping in
each function. A run of IPs in a VMA with no usable build ID will
repeat the lookup for every frame: find_vma() in the non-sleepable
path, a VMA lock and a blocking build_id_parse_file() in the sleepable.

Factor the per-call cache into a shared struct stack_map_build_id_cache
with two independent slots [2][3], used by both functions:

  * resolved   - last VMA that produced a build ID (file, build_id and
                 range), reused to skip the lookup and the parse;
  * unresolved - last VMA with no usable build ID (range only), reused to
                 emit a raw IP without another lookup or parse.

Keeping the slots independent means a build-ID-less VMA no longer evicts
the last resolved build ID, so a trace alternating between a binary and a
region without one stops re-resolving the binary on every return.

The shared lookup tests [vm_start, vm_end), matching the sleepable path;
the non-sleepable path previously reused a build ID for ip == vm_end
(range_in_vma() is inclusive) and now re-resolves it correctly.

Subject: [PATCH 4328/5214] bpf: Emit verbose message when prog-specific
 btf_struct_access rejects a write

When BPF_WRITE goes through a PTR_TO_BTF_ID register, check_ptr_to_btf_access()
delegates to env->ops->btf_struct_access(). Most implementations
(bpf_scx_btf_struct_access, tc_cls_act_btf_struct_access, etc.) return
-EACCES for disallowed fields without logging anything, so the verifier
rejects the program with an empty message. For example a scx program doing

  1: R1=trusted_ptr_task_struct()

Subject: [PATCH 4329/5214] bpf: Allow type tag BTF records to succeed other
 modifier records

llvm commit [1] allowed attaching type tag records to modifier BTF
records. This is useful for using typedefs that encompass a base type
and a type tag, e.g.:

typedef struct rbtree __arena rbtree_t;

Modify btf_check_type_tags() so that it allows this sequence of records.
The function now only checks for record loops in BTF modifier record
chains. Rename to btf_check_modifier_chain_length to reflect this.

Also expand the BTF modifier traversal code to take into account that
type record can be interleaved with other modifier records. In effect
this means traversing all modifiers to collect the type tags.

Also modify existing selftests to now accept modifier records (const,
typedef) that point to type tag records.

Subject: [PATCH 4330/5214] bpf: Add missing access_ok call to copy_user_syms

As reported by sashiko we use __get_user without prior access_ok call on the
user space pointer. Adding the missing call for the whole pointer array.

Plus removing the err check in the error path, because it's not needed and
also we can return -ENOMEM directly from the first kvmalloc_array fail path.

Subject: [PATCH 4331/5214] bpftool: Fix vmlinux BTF leak in cgroup commands

bpftool cgroup show and tree call libbpf_find_kernel_btf() to
resolve attach_btf names, but never release the returned BTF object.

For cgroup tree, do_show_tree_fn() is called once for each cgroup
visited by nftw(). When more than one cgroup has attached programs,
each callback overwrites btf_vmlinux with a new object and loses the
previous allocation.

Load vmlinux BTF only once during a tree walk and release it when
cgroup show or tree completes. Reset btf_vmlinux_id at the same time
so batch mode starts with clean state.

Subject: [PATCH 4332/5214] bpf: zero-initialize the fib lookup flow struct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

bpf_ipv4_fib_lookup() and bpf_ipv6_fib_lookup() build the flow key on
the stack with a bare "struct flowi4 fl4;" / "struct flowi6 fl6;" and
fill it field by field, but never set flowi4_l3mdev / flowi6_l3mdev.

On the non-DIRECT path the lookup goes through the fib rules whenever the
netns has custom rules, which a VRF installs:

	bpf_ipv4_fib_lookup() -> fib_lookup() -> __fib_lookup()
	  -> l3mdev_update_flow()   reads !fl->flowi_l3mdev
	  -> fib_rules_lookup() -> fib_rule_match()
	       -> l3mdev_fib_rule_match()   uses fl->flowi_l3mdev

l3mdev_update_flow() resolves the l3mdev master from the ingress device
only while the field is still zero. Left at a nonzero stack value the
resolution is skipped, and l3mdev_fib_rule_match() then tests that value
as an ifindex, so the VRF master is not resolved and the rule fails to
match: an ingress enslaved to a VRF can fail to select its table. FIB
rules matching on an L3 master device (l3mdev_fib_rule_iif_match()/
_oif_match()) read the same value, so an "ip rule iif/oif <vrf>"
mismatches the same way.

Zero-initialize the whole flow struct rather than adding one more
field assignment, so any flowi field added later is covered too.
ip_route_input_slow() likewise zeroes the field before its input lookup.

CONFIG_INIT_STACK_ALL_ZERO masks this by default, but it depends on
compiler support (CC_HAS_AUTO_VAR_INIT_ZERO), so INIT_STACK_NONE builds,
including older toolchains that fall back to it, are exposed. Built with
INIT_STACK_ALL_PATTERN, a plain bpf_fib_lookup (no VLAN, no DIRECT) over a
VRF slave whose destination is routed only in the VRF table returns
BPF_FIB_LKUP_RET_NOT_FWDED, and resolves with this patch. On the default
config the lookup succeeds either way, so ordinary testing does not catch
the bug.

Subject: [PATCH 4334/5214] bpf: Fix effective prog array index with
 BPF_F_PREORDER

replace_effective_prog() and purge_effective_progs() located the slot in
the effective array by walking the program hlist and counting entries
linearly. That count does not match the array layout: compute_effective_
progs() places BPF_F_PREORDER programs at the front (ancestor cgroup
first, attach order within a cgroup) and the rest after them (descendant
cgroup first). So when a preorder program is present, the linear hlist
position no longer equals the program's index in the effective array.

For replace_effective_prog() (bpf_link_update()) this overwrote the
wrong slot, corrupting the effective order. For purge_effective_progs(),
it could dummy out a slot belonging to a different program and leave the
detached program in the array while bpf_prog_put() drops its reference,
i.e. a use-after-free.

Fix both by replaying compute_effective_progs()'s placement (including
the per-cgroup preorder reversal) in a shared effective_prog_pos()
helper. Identify the entry by its struct bpf_prog_list pointer rather
than by (prog, link) value, so the lookup resolves to exactly the
attachment the syscall selected even when the same bpf_prog is attached
to several cgroups in the hierarchy.

Add a cgroup_preorder case that attaches a normal and a BPF_F_PREORDER
program to a cgroup (effective order [2, 1]), then replaces the normal
link's program via bpf_link_update() and checks the effective order
becomes [2, 3] — i.e. only the non-preorder slot changes. Without the
replace_effective_prog() fix the array is corrupted and the order is
wrong.

Subject: [PATCH 4336/5214] erofs: remove fscache backend entirely

EROFS over fscache was introduced to provide image lazy pulling
functionality. After the feature landed, the fscache subsystem made
netfs a new hard dependency, which is unexpected for a local filesystem
and has an kernel-defined caching hierarchy which could be inflexible
compared to the fanotify pre-content hooks. Therefore, this feature has
been deprecated for almost two years.

As EROFS file-backed mounts and fanotify pre-content hooks both upstream
for a while and already providing equivalent functionality (erofs-utils
has supported fanotify pre-content hooks), let's remove the fscache
backend now.

The main application of this feature is Nydus [1], and they plan to move
to use fanotify pre-content hooks in the near future too.

I hope this patch can be merged into Linux 7.2, which is also motivated
by newly found implementation issues [2][3] that are not worth
investigating given the deprecation and limited development resources.
The associated fscache/cachefiles cleanup patch will follow separately
through the vfs tree (netfs) later: it seems fine since the codebase is
isolated by CONFIG_CACHEFILES_ONDEMAND.

Subject: [PATCH 4337/5214] pwrseq: core: fix use-after-free in
 pwrseq_debugfs_seq_next()

pwrseq_debugfs_seq_next() declares 'next' with __free(put_device),
which causes put_device() to be called on the returned pointer when
the variable goes out of scope.  This results in a use-after-free
since the seq_file framework receives a pointer whose reference has
already been dropped.

Simply removing __free(put_device) would fix the UAF but would leak
the reference acquired by bus_find_next_device(), as stop() only
calls up_read(&pwrseq_sem) and never releases the device reference.

Fix this by making the reference counting consistent across all
seq_file callbacks, matching the standard pattern used by PCI and
SCSI:

- start(): use get_device() so it returns a referenced pointer.
- next(): explicitly put_device(curr) to release the previous
  device's reference (no NULL check needed - the seq_file framework
  only calls next() while the previous return was non-NULL).
- stop(): put_device(data) to release the last iterated device's
  reference, with a NULL guard since stop() may be called with NULL
  when start() returned NULL or next() reached end-of-sequence.

Subject: [PATCH 4339/5214] power: sequencing: fix ABBA deadlock in
 pwrseq_device_unregister()

The pwrseq core takes three locks in consistent order everywhere:

  pwrseq_sem -> pwrseq->rw_lock -> pwrseq->state_lock

pwrseq_get() -> pwrseq_match_device() takes pwrseq_sem for reading, then
rw_lock for reading. pwrseq_power_on()/pwrseq_power_off() take rw_lock
for reading and then state_lock.

pwrseq_device_unregister() is the only exception, it takes: state_lock,
then rw_lock for writing and finally pwrseq_sem for writing. This created
two potential ABBA deadlock situations that sashiko pointed out.

  - pwrseq_power_on/off() take rw_lock for reading then state_lock, while
    pwrseq_unregister() takes state_lock then rw_lock for writing
  - pwrseq_get() takes pwrseq_sem for reading then rw_lock for reading,
    while pwrseq_unregister() takes rw_lock for writing then pwrseq_sem
    for writing

Reorder the unregister path to taking pwrseq_sem for writing -> rw_lock
for writing and drop the state_lock entirely. This is safe as
enable_count is only ever written under rw_lock held for read (via
pwrseq_unit_enable()/disable(), reached only from pwrseq_power_on/off()),
so holding rw_lock for writing already excludes every other writer and
reader and the active-users WARN() stays race-free without state_lock.

gpiochip_set_multiple() falls back to setting lines one by one when the
chip does not provide set_multiple(). If the fallback path receives an
empty mask, the loop is skipped and ret is returned without being
initialized.

Initialize ret to 0 so an empty mask is treated as a successful no-op.

Subject: [PATCH 4342/5214] drm/edid: fix OOB read in drm_parse_tiled_block()

drm_parse_tiled_block() casts the DisplayID block to a
struct displayid_tiled_block and reads the full fixed layout up to
tile->topology_id[7] without checking block->num_bytes. The DisplayID
iterator only validates the declared payload length, so a crafted EDID
can advertise a tiled-display block (tag DATA_BLOCK_TILED_DISPLAY, or
DATA_BLOCK_2_TILED_DISPLAY_TOPOLOGY for v2.0) with a small num_bytes at
the end of a DisplayID extension. The read then runs past the end of the
exact-sized kmemdup()'d EDID allocation, a heap out-of-bounds read.

Reject blocks shorter than the spec's 22-byte tiled payload before
reading the fixed struct, as drm_parse_vesa_mso_data() already does.

 16IAP7

The Yoga 7 16IAP7 (board LNVNB161216, codec SSID 17aa:386a) has pin
complex 0x17 (bass speakers) wrongly reported as unconnected, causing
only one of four speaker pins (0x14) to be configured and resulting in
mono/tinny audio.

SOF corrupts the PCI subsystem ID to 17aa:0000, preventing SND_PCI_QUIRK
from matching. HDA_CODEC_QUIRK is used instead, which matches against
codec->core.subsystem_id read directly from the HDA codec register and
unaffected by the SOF bug.

Applies ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN, the same fixup used for
the Yoga 7 14IAL7, which corrects pin 0x17's default configuration and
enables both speaker pairs.

Subject: [PATCH 4345/5214] drm/sysfb: Do not page-align visible size of the
 framebuffer

Only return the actually visible size of the system framebuffer in
drm_sysfb_get_visible_size_si(). Drivers use this size value for
reserving access to framebuffer memory. Increasing the value can
make later attempts to do so fail.

Subject: [PATCH 4346/5214] drm/sysfb: Avoid possible truncation with
 calculating visible size

Calculating the visible size of the system framebuffer can result in
truncation of the result. The calculation uses 32-bit arithmetics,
which can overflow if the values for height and stride are large. Fix
the issue by multiplying with mul_u32_u32().

Subject: [PATCH 4347/5214] drm/sysfb: Return errno code from
 drm_sysfb_get_visible_size()

Change the return type of drm_sysfb_get_visible_size() to s64 so
that it returns a possible errno code from _get_validated_size0().
Fix callers to handle the errno code.

The currently returned unsigned type converts an errno code to a
very large size value, which drivers interpret as visible size of
the system framebuffer. Later efforts to reserve the framebuffer
resource fail.

The bug has been present since efidrm and vesadrm got merged. It
was then part of each driver.

Subject: [PATCH 4348/5214] drm/sysfb: Avoid truncating maximum stride

Passing a maximum as 64-bit type to drm_sysfb_get_validated_int0()
can truncate the value to 32 bits. Use drm_sysfb_get_validated_size0(),
which uses 64-bit arithmetics. Then test the returned stride against
the limits of int to avoid truncations in the returned value. A valid
stride is in the range of [1, INT_MAX] inclusive.

Subject: [PATCH 4351/5214] time: Fix off-by-one in compat settimeofday() usec
 validation

The compat version of settimeofday() uses '>' instead of '>=' when
validating tv_usec against USEC_PER_SEC, allowing the value 1000000 to pass
the check. After the subsequent conversion to nanoseconds (tv_nsec *=
NSEC_PER_USEC), this results in tv_nsec == NSEC_PER_SEC, which violates the
timespec invariant that tv_nsec must be strictly less than NSEC_PER_SEC.

The native settimeofday() was already fixed in commit ce4abda5e126 ("time:
Fix off-by-one in settimeofday() usec validation"), but the compat
counterpart was missed.

Fix it by using '>=' to reject tv_usec values outside the valid range [0,
USEC_PER_SEC - 1].

Subject: [PATCH 4352/5214] debugobjects: Plug race against a concurrent OOM
 disable

syzbot reported a puzzling splat:

   WARNING: kernel/time/hrtimer.c:443 at stub_timer+0xa/0x20

stub_timer() is installed as timer callback function in
hrtimer_fixup_assert_init(), which is invoked when
debug_object_assert_init() can't find a shadow object. In that case debug
objects emits a warning about it before invoking the fixup.

Though the provided console log lacks this warning and instead has the
following a few seconds before the splat:

     ODEBUG: Out of memory. ODEBUG disabled

So the object was looked up in debug_object_assert_init() and the lookup
failed due a concurrent out of memory situation which disabled debug
objects and freed the shadow objects:

debug_object_assert_init()
        if (!debug_objects_enabled)
        	return;                         obj = alloc();
                				if (!obj) {
							// Out of memory
                                                	debug_objects_enabled = false;
                                                        free_objects();
        obj = lookup_or_alloc();

        // The lookup failed because the other side
        // removed the objects, so this returns
        // an error code as the object in question
        // is not statically initialized

	if (!IS_ERR_OR_NULL(obj))
        	return;
        if (!obj) {
        	debug_oom();
                return;
        }

        print(...)
           if (!debug_objects_enabled)
                return;

        fixup(...)

The debug object splat is skipped because debug_objects_enabled is false,
but the fixup callback is invoked unconditionally, which makes the timer
disfunctional.

This is only a problem in debug_object_assert_init() and
debug_object_activate() as both have to handle statically initialized
objects and therefore must handle the error pointer return case
gracefully. All other places only handle the found/not found case and the
NULL pointer return is a signal for OOM. Otherwise they get a valid shadow
object.

Plug the hole by checking whether debug objects are still enabled before
invoking the print and fixup function in those two places.

Subject: [PATCH 4353/5214] sched_ext: Move sources under kernel/sched/ext/

The sched_ext sources had grown to ten ext* files directly under
kernel/sched/. Move them into a new kernel/sched/ext/ subdirectory and drop
the now-redundant ext_ prefix. ext.c/h keep their names.

  kernel/sched/ext.{c,h}       -> kernel/sched/ext/ext.{c,h}
  kernel/sched/ext_internal.h  -> kernel/sched/ext/internal.h
  kernel/sched/ext_types.h     -> kernel/sched/ext/types.h
  kernel/sched/ext_idle.{c,h}  -> kernel/sched/ext/idle.{c,h}
  kernel/sched/ext_cid.{c,h}   -> kernel/sched/ext/cid.{c,h}
  kernel/sched/ext_arena.{c,h} -> kernel/sched/ext/arena.{c,h}

The include paths in build_policy.c and sched.h, the MAINTAINERS glob, and a
few documentation and comment references are updated to match. No code or
symbol changes.

Subject: [PATCH 4354/5214] irqchip/imgpdc: Fix resource leak, add missing
 chained handler cleanup on remove

The driver allocates domain generic chips using
irq_alloc_domain_generic_chips() during probe and sets up chained
handlers using irq_set_chained_handler_and_data(). However, on driver
removal, the generic chips are not freed and the chained handlers are
not removed.

The generic chips remain on the global gc_list and may later be accessed by
generic interrupt chip suspend, resume, or shutdown callbacks after the
driver has been removed, potentially resulting in a use-after-free and
kernel crash.

The chained handlers that were installed in probe for peripheral and
syswake interrupts are also left dangling, which can lead to spurious
interrupts accessing freed memory.

Fix these issues by:

  - Setting IRQ_DOMAIN_FLAG_DESTROY_GC flag in domain->flags, so the
    core code automatically removes generic chips when irq_domain_remove()
    is called

  - Clearing all chained handlers with NULL in pdc_intc_remove()

Subject: [PATCH 4355/5214] ASoC: cs530x: Fix expected MCLK rates for
 CS5302/4/8

When this driver was first added, it accepted rates of 24.56 MHz and
22.572 MHz for the MCLK when PLL bypass is enabled.

These rates seem to have no basis in the datasheets and were thus replaced
with 45.1584 MHz and 49.152 MHz, respectively, in commit e7ab858390f2
("ASoC: cs530x: Correct MCLK reference frequency values").

While the new rates are indeed correct for the CS4xxx ICs[0][1][2][3],
they are incorrect for the CS530x ICs the driver was originally written to
support as the MCLK frequencies are halved there[4][5][6].

Fix this by checking against the correct type-appropriate rates.

While at it, drop the CS530X_SYSCLK_REF_* macros. They arguably confuse
more than they help, especially as they are not applicable to the
cs5302/4/8.

Subject: [PATCH 4357/5214] fscrypt: Fix key setup in edge case with multiple
 data unit sizes

The addition of support for customizable data unit sizes introduced an
edge case where a file's contents can be en/decrypted with the wrong
data unit size.  It occurs when there are multiple v2 policies that:

- Have *different* data unit sizes, via the log2_data_unit_size field

- Share the same master_key_identifier, contents_encryption_mode, and
  either FSCRYPT_POLICY_FLAG_DIRECT_KEY,
  FSCRYPT_POLICY_FLAG_IV_INO_LBLK_32, or
  FSCRYPT_POLICY_FLAG_IV_INO_LBLK_64

- Are being used on the same filesystem, which also must be mounted with
  the "inlinecrypt" mount option.

Fortunately this edge case doesn't actually occur in practice.  I just
found it via code review.  But it needs to be fixed regardless.

The bug is caused by the data unit size not being fully considered when
blk_crypto_keys are cached in mk_direct_keys, mk_iv_ino_lblk_32_keys,
and mk_iv_ino_lblk_64_keys.  They're differentiated only by master key,
encryption mode, and flag.  However, each one actually has a data unit
size too.  Only the first data unit size that is cached is used.

To fix this, start using the data unit size to differentiate the cached
keys.  For several reasons, including avoiding increasing the size of
struct fscrypt_master_key, just replace all three arrays with a single
linked list instead of changing them into two-dimensional arrays.  This
works well when considering that in practice at most 2 entries are used
across all three arrays, so it was already mostly wasted space.

For simplicity, make the list also take over the publish/subscribe of
the prepared key itself.  That is, create separate list nodes for
blk_crypto_keys vs crypto_skciphers, and add nodes to the list only when
their key is actually prepared.  (Note that the legacy
fscrypt_direct_keys table in fs/crypto/keysetup_v1.c already works this
way.)  This eliminates the need for the additional memory barriers when
reading and writing the fields of struct fscrypt_prepared_key.

Note that I technically should have included the data unit size in the
HKDF info string as well.  But it's too late to change that.

Fixes: 5b1188847180 ("fscrypt: support crypto data unit size less than filesystem block size")

Subject: [PATCH 4358/5214] fscrypt: Replace mk_users keyring with simple list

Change mk_users (the set of user claims to an fscrypt master key) from a
'struct key' keyring to a simple linked list.

It's still a collection of 'struct key' for quota tracking.  It was
originally thought to be natural that a collection of 'struct key'
should be held in a 'struct key' keyring.  In reality, it's just been
causing problems, similar to how using 'struct key' for the filesystem
keyring caused problems and was removed in commit d7e7b9af104c
("fscrypt: stop using keyrings subsystem for fscrypt_master_key").

Commit d3a7bd420076 ("fscrypt: clear keyring before calling key_put()")
fixed mk_users cleanup to be synchronous.  But that apparently wasn't
enough: the keyring subsystem's redundant locking is still generating
lockdep false positives due to the interaction with filesystem reclaim.

With the simple list, the redundant locking and lockdep issue goes away.

Of course, searching a linked list is linear-time whereas the
'struct key' keyring used a fancy constant-time associative array.  But
that's fine here, since in practice there's just one entry in the list.
In fact the new code is much faster in practice, since it's much smaller
and doesn't have to convert the kuid_t into a string to search for it.

Subject: [PATCH 4359/5214] f2fs: annotate lockless last_time[] accesses

f2fs stores mount-wide activity timestamps in sbi->last_time[] and
samples them from background discard, GC, and balance paths without a
dedicated lock. The timestamps are used as best-effort heuristics to
decide whether background work should run now or sleep a bit longer.

The current helpers use plain loads and stores, so KCSAN can report races
between frequent foreground updates and background readers. Exact
freshness is not required here, but the intentional lockless accesses
should be marked explicitly.

Use WRITE_ONCE() in f2fs_update_time() and READ_ONCE() in
f2fs_time_over() and f2fs_time_to_wait(). This preserves the existing
heuristic behavior and avoids adding locking to hot paths.

Subject: [PATCH 4360/5214] f2fs: annotate lockless NAT counter reads

nat_cnt[] is updated while callers hold nat_tree_lock, but F2FS samples
the counters locklessly in f2fs_available_free_memory(),
excess_dirty_nats(), and excess_cached_nats(). Those helpers only steer
cache reclaim and background sync heuristics; they do not control NAT
entry lifetime or checkpoint correctness.

Document the intent with data_race(READ_ONCE()) and a short comment
instead of adding locking to the balance path.

Subject: [PATCH 4361/5214] f2fs: Add trace_f2fs_fault_report

Add trace_f2fs_fault_report to trigger reporting upon f2fs_bug_on,
need_fsck, stop_checkpoint, and handle_eio. Since f2fs_bug_on and
need_fsck can be triggered in hundreds of scenarios, define set_sbi_flag
as a macro to help capture the effective fault function and line number.

Subject: [PATCH 4362/5214] f2fs: optimize representative type determination in
 GC

In large section mode, do_garbage_collect() previously determined the
section's representative type by looking only at the first segment of
the section. However, if data was fsynced into an area previously used
as a node section, and this area is recovered during roll-forward
recovery after sudden power off (SPO), GC would incorrectly assume the
section's type based on an empty or obsolete first segment. This caused
the recovered data segment to be misunderstood as being stuck inside a
node section, triggering false inconsistency panics (Inconsistent
segment type in SSA and SIT) and subsequent mount failures.

This patch optimizes do_garbage_collect() to determine the section's
representative type by identifying the first segment that actually
contains valid blocks (valid_blocks > 0) during the main GC loop. This
eliminates false alarms from empty/obsolete leading segments while
maintaining strict section-level type consistency checks for genuine
corruption.

F2FS did not collect iostat latency for direct IO reads and writes,
hook iomap_dio_ops.submit_io to bind an iostat context and record the
submission timestamp. Replace bi_end_io with f2fs_dio_end_bio() to
collect IO latency on completion before calling back to the original
iomap_dio_bio_end_io(), to add iostat latency tracking support for
F2FS DIO.

 - f2fs_write_single_data_page
  - f2fs_do_write_data_page
   - folio_start_writeback  --- set writeback flag on folio
   - f2fs_outplace_write_data

  - f2fs_balance_fs
   - wake_up(gc_thread)
   : wake up gc thread to run foreground GC
   - finish_wait(fggc_wq)
   : wait on the waitqueue --- wait on GC thread to finish the work
									- truncate_inode_pages_range
									 - __filemap_get_folio(, FGP_LOCK)  --- lock folio
									 - truncate_inode_partial_folio
									  - folio_wait_writeback            --- wait on writeback being cleared
					- do_garbage_collect
					 - move_data_page
					  - f2fs_get_lock_data_folio
					   - lock on folio  --- blocked on folio's lock

In order to avoid such deadlock, let's call below functions to commit
cached bios in GC_MERGE path of f2fs_balance_fs() as the same as we did
in NOGC_MERGE path.

- f2fs_submit_all_merged_ipu_writes(sbi);

Subject: [PATCH 4367/5214] f2fs: fix missing read bio submission on large
 folio error

f2fs_read_data_large_folio() can keep a read bio across multiple
readahead folios.  If a later folio hits an error before any of its
blocks are added to the bio, folio_in_bio is false and the current error
path returns immediately after ending that folio.

This can leave the bio accumulated for earlier folios unsubmitted.  Those
folios then never receive read completion, and readers can wait
indefinitely on the locked folios.

Route errors through the common out path so any pending bio is submitted
before returning.  Stop consuming more readahead folios once an error is
seen, and only wait on and clear the current folio when it was actually
added to the bio.

Subject: [PATCH 4368/5214] f2fs: pass correct iostat type for single node
 writes

f2fs_write_single_node_folio() takes an io_type argument, but still
passes FS_GC_NODE_IO to __write_node_folio() unconditionally.

This was harmless while the helper was only used by
f2fs_move_node_folio(), whose caller passes FS_GC_NODE_IO. However,
commit fe9b8b30b971 ("f2fs: fix inline data not being written to disk
in writeback path") made f2fs_inline_data_fiemap() call the helper with
FS_NODE_IO for FIEMAP_FLAG_SYNC.

Honor the caller supplied io_type so inline-data FIEMAP sync writeback is
accounted as normal node IO instead of GC node IO, while the GC path
continues to pass FS_GC_NODE_IO explicitly.

Subject: [PATCH 4369/5214] f2fs: validate compress cache inode only when
 enabled

F2FS_COMPRESS_INO() uses NM_I(sbi)->max_nid as the synthetic inode
number for the compressed page cache inode. That inode only exists when
the compress_cache mount option is enabled.

When compress_cache is disabled, max_nid is outside the valid inode
range. A corrupted directory entry that points to ino == max_nid should
therefore be rejected by f2fs_check_nid_range(). However, is_meta_ino()
currently treats F2FS_COMPRESS_INO() as a meta inode unconditionally,
so f2fs_iget() bypasses do_read_inode() and its nid range check, and
instantiates a fake internal inode instead.

Gate the compressed cache inode case on COMPRESS_CACHE, matching
f2fs_init_compress_inode(). With compress_cache disabled, ino ==
max_nid now follows the normal inode path and is rejected as an
out-of-range nid.

Subject: [PATCH 4370/5214] f2fs: avoid false shutdown fserror reports

F2FS records image errors and checkpoint-stop reasons through the same
s_error_work worker.  The ordinary f2fs_handle_error() path only updates
s_errors, but the worker still calls fserror_report_shutdown()
unconditionally after committing the superblock.

As a result, a metadata corruption report can be followed by a synthetic
FAN_FS_ERROR event with ESHUTDOWN and an invalid superblock file handle,
even though no stop reason was recorded.

Track whether save_stop_reason() actually changed the stop_reason array
and only report the shutdown fserror for that case.  Pure s_errors updates
still commit the superblock, but no longer generate a false shutdown event.

	count = ADDRS_PER_PAGE(dn.node_folio, inode);

	count -= dn.ofs_in_node;
	f2fs_bug_on(sbi, count < 0);

The fuzz test will trigger above bug_on in f2fs.

The root cause should be: in the corrupted inode, there is a direct node
which has the same ino and nid in its footer, so in f2fs_do_truncate_blocks(),
after f2fs_get_dnode_of_data() finds such dnode:
1) ADDRS_PER_PAGE(dn.node_folio, inode) will return 923
2) once dn.ofs_in_node points to addr[923, 1017]
Then it will trigger the system panic.

Let's introduce NODE_TYPE_NON_IXNODE to indicate current node should
not be an inode or xattr node, and then use it in below path to detect
inconsistent node chain in inode mapping table:

- f2fs_do_truncate_blocks
 - f2fs_get_dnode_of_data
  - f2fs_get_node_folio_ra
   -  __get_node_folio
    - f2fs_sanity_check_node_footer
     - case NODE_TYPE_NON_IXNODE -> check whether it is inode|xnode

Subject: [PATCH 4374/5214] f2fs: honor per-I/O write streams for direct writes

io_uring can pass a per-I/O write stream through kiocb->ki_write_stream,
and block direct I/O propagates that value to bio->bi_write_stream.

F2FS added FDP stream mapping for DATA writes, but its direct write
submit hook always rewrites bio->bi_write_stream from the inode write
hint and F2FS temperature. As a result, a direct write with an explicit
io_uring write_stream is submitted to the F2FS-selected stream instead
of the user-requested stream.

Validate an explicit write stream before starting F2FS direct I/O, pass
the kiocb through the iomap private pointer, and preserve the per-I/O
stream in the direct write bio. When no per-I/O stream is supplied, keep
using the existing F2FS temperature-to-stream mapping.

Subject: [PATCH 4375/5214] f2fs: validate orphan inode entry count

f2fs_recover_orphan_inodes() trusts the orphan block entry_count when
replaying orphan inodes from the checkpoint pack. A corrupted entry_count
larger than F2FS_ORPHANS_PER_BLOCK makes the recovery loop read past the
ino[] array and interpret footer or following data as inode numbers.

On a crafted image, mounting an unpatched kernel can drive orphan recovery
into f2fs_bug_on() and panic the kernel. Validate entry_count before
consuming entries so corrupted checkpoint data fails the mount with
-EFSCORRUPTED and requests fsck instead.

Set ERROR_INCONSISTENT_ORPHAN as well, so the corruption reason can be
recorded in the superblock s_errors[] field. This gives fsck a persistent
hint even though mount-time orphan recovery failure may leave no chance to
persist SBI_NEED_FSCK through a checkpoint.

Subject: [PATCH 4376/5214] f2fs: keep atomic write retry from zeroing original
 data

A partial atomic write reserves a block in the COW inode before reading the
original data page for the untouched bytes in that page.

If that read fails, write_begin returns an error but leaves the COW inode
entry as NEW_ADDR. A retry of the same partial write then finds the COW
entry, treats it as existing COW data, and f2fs_write_begin() zeroes the
whole folio because blkaddr is NEW_ADDR.

If the retry is committed, the bytes outside the retried write range are
committed as zeroes instead of preserving the original file contents.

Only use the COW inode as the read source when it already has a real data
block. If the COW entry is still NEW_ADDR, treat it as a reservation to
reuse: keep reading the old data from the original inode and avoid
reserving or accounting the same atomic block again.

Subject: [PATCH 4377/5214] f2fs: skip inode folio lookup for cached overwrite

prepare_write_begin() first gets the inode folio and builds a dnode,
then checks the read extent cache. For an ordinary overwrite of a
non-inline and non-compressed file, an extent-cache hit already gives the
data block address and the following path does not need to allocate or
update any node state.

Check the read extent cache before fetching the inode folio for that
narrow case. Keep the existing paths for inline data, compressed files,
and writes that may extend past EOF, where the helper may need inline
conversion, compression preparation, or block reservation.

This avoids a node-folio lookup in the buffered overwrite fast path when
the mapping is already cached.

In a QEMU/KASAN x86_64 VM, using a small buffered overwrite workload on
an existing 1MiB file, median time improved as follows:

  64-byte overwrites:  1724.93 ns/write -> 1560.24 ns/write
  256-byte overwrites: 1713.38 ns/write -> 1577.85 ns/write

Function profiling of 20k 64-byte overwrites showed
f2fs_get_inode_folio() calls drop from 20004 to 4.

			      ...);

and f2fs_grab_read_bio() decides whether to schedule fs-layer decryption
(STEP_DECRYPT) for the bio based on that inode via
fscrypt_inode_uses_fs_layer_crypto().

However, the folio being filled belongs to the original inode
(folio->mapping->host == inode), and the data stored in the COW block was
encrypted (or left as plaintext) using the original inode's context, not
the COW inode's -- see f2fs_encrypt_one_page(), which keys off
fio->page->mapping->host.  fscrypt_decrypt_pagecache_blocks() likewise
operates on folio->mapping->host.

The COW inode is created as a tmpfile in the parent directory and inherits
its encryption policy from there.  With test_dummy_encryption the newly
created COW inode gets the dummy policy and becomes encrypted, while a
pre-existing regular file -- created before the policy applied, e.g.
already present in the on-disk image -- stays unencrypted.  The read
path then sets STEP_DECRYPT based on the encrypted COW inode and calls
fscrypt_decrypt_pagecache_blocks() on a folio whose host (the unencrypted
original inode) has a NULL ->i_crypt_info, dereferencing it:

  Oops: general protection fault, probably for non-canonical address ...
  KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f]
  RIP: 0010:fscrypt_decrypt_pagecache_blocks+0xa0/0x310

   process_one_work+0x91c/0x1a40
   worker_thread+0x677/0xe90
   kthread+0x2bc/0x3a0

The COW inode is only needed to locate the on-disk block, and that block
address is already resolved into @blkaddr by prepare_atomic_write_begin()
via __find_data_block(cow_inode, ...); f2fs_submit_page_read() then reads
from that physical @blkaddr directly, so the inode argument only selects
the post-read crypto context, not which block is fetched.  Reading with
@inode therefore returns the same (latest, not-yet-committed) COW data,
while making both the fs-layer decryption decision and the inline crypto
path use the correct (original inode's) key.

With the COW inode no longer used at the read site, the use_cow flag has no
remaining consumer; drop it from f2fs_write_begin() and
prepare_atomic_write_begin().

Subject: [PATCH 4379/5214] f2fs: validate inline dentry name lengths before
 conversion

Inline dentry conversion copies names out of the inline dentry area
before checking that each recorded name length fits in the available
filename slots.

A corrupted image can therefore make the conversion path read past
the inline filename storage while building the regular dentry block.

Validate each inline dentry name length against the inline filename
area before copying it.

The f2fs dentry lookup path can use the on-disk name length before
checking that the name fits in the dentry filename area.  A corrupted
dentry can then make lookup read beyond the filename slots.

The bounds check needs to happen before any comparison that consumes
the name length from disk.

Reject dentries with invalid name lengths before comparing their names.

 files

F2FS large folios are only enabled for immutable non-compressed files.
Writable open and writable mmap reject such mappings, but truncate(2)
through f2fs_setattr() misses the same guard.

If FS_IMMUTABLE_FL is cleared while the inode is still cached, the mapping
can keep large-folio support and ATTR_SIZE can change i_size. Reject size
changes in that state.

Subject: [PATCH 4385/5214] Revert "f2fs: remove non-uptodate folio from the
 page cache in move_data_block"

This reverts commit 9609dd704725a40cd63d915f2ab6c44248a44598.

The kernel panics are keeping to be reported especially when the f2fs
partition get almost full. By investigation, we find that the reason is
one f2fs page got freed to buddy without being deleted from LRU and the
root cause is the race happened in [2] which is enrolled by this commit.

There are 3 race processes in this scenario, please find below for their
main activities.

The changed code in move_data_block() lets the GC path evict the tail-end
folio from the page cache through folio_end_dropbehind().  Once
folio_unmap_invalidate() removes the folio from mapping->i_pages, the
page-cache references for all pages in the folio are dropped.  The folio
is then kept alive only by temporary external references, which allows a
later split to operate on a folio whose subpages are no longer protected
by page-cache references.

After the page-cache references are gone, split_folio_to_order() can
split the big folio into individual pages and put the resulting subpages
back on the LRU.  For tail pages beyond EOF, split removes them from the
page cache and drops their page-cache references.  A tail page can then
remain on the LRU with PG_lru set while holding only the split caller's
temporary reference.  When free_folio_and_swap_cache() drops that final
reference, the page enters the final folio_put() release path.

In parallel, folio_isolate_lru() can observe the same tail page with a
non-zero refcount and PG_lru set.  It clears PG_lru before taking its own
reference.  If this races with the final folio_put() from the split path,
__folio_put() sees PG_lru already cleared and skips lruvec_del_folio().
The page is then freed back to the allocator while its lru links are
still present in the LRU list.  A later LRU operation on a neighboring

Subject: [PATCH 4386/5214] f2fs: validate ACL entry sizes in
 f2fs_acl_from_disk()

f2fs_acl_count() only validates the aggregate ACL xattr length. A
malformed ACL can still place ACL_USER or ACL_GROUP in a slot that only
contains struct f2fs_acl_entry_short bytes, and f2fs_acl_from_disk()
then reads entry->e_id before verifying that a full entry fits.

Require a short entry before reading e_tag and e_perm, and require a
full entry before reading e_id for ACL_USER and ACL_GROUP. Return
-EFSCORRUPTED from these new truncated-entry checks, while keeping the
pre-existing -EINVAL paths unchanged.

Validation reproduced this kernel report:

Subject: [PATCH 4387/5214] f2fs: bound i_inline_xattr_size for
 non-inline-xattr inodes

When the flexible_inline_xattr feature is enabled, do_read_inode() loads
the on-disk i_inline_xattr_size unconditionally:

	if (f2fs_sb_has_flexible_inline_xattr(sbi))
		fi->i_inline_xattr_size = le16_to_cpu(ri->i_inline_xattr_size);

but sanity_check_inode() only range-checks it when the inode also has the
FI_INLINE_XATTR flag set.  An inode that carries an inline dentry or inline
data but not FI_INLINE_XATTR -- the normal layout for an inline
directory -- therefore keeps a fully attacker-controlled
i_inline_xattr_size from a crafted image.

get_inline_xattr_addrs() returns that value with no flag gating, so it
feeds the inode geometry:

	MAX_INLINE_DATA()  = 4 * (CUR_ADDRS_PER_INODE - i_inline_xattr_size - 1)
	NR_INLINE_DENTRY() = MAX_INLINE_DATA() * BITS_PER_BYTE / (...)
	addrs_per_page()   = CUR_ADDRS_PER_INODE - i_inline_xattr_size

A large i_inline_xattr_size drives MAX_INLINE_DATA() and NR_INLINE_DENTRY()
negative, so make_dentry_ptr_inline() sets d->max (int) to a negative
value.  The inline directory walk then compares an unsigned long bit_pos
against that negative d->max, which is promoted to a huge unsigned bound,
and reads far past the inline area:

	while (bit_pos < d->max)		/* fs/f2fs/dir.c */
		... test_bit_le(bit_pos, d->bitmap) / d->dentry[bit_pos] ...

Mounting a crafted image and reading such a directory triggers an
out-of-bounds read in f2fs_fill_dentries(); the same underflow also
corrupts ADDRS_PER_INODE for regular files.

Validate i_inline_xattr_size against MAX_INLINE_XATTR_SIZE whenever the
flexible_inline_xattr feature is enabled -- i.e. whenever the value is
loaded from disk and consumed -- and keep the lower MIN_INLINE_XATTR_SIZE
bound gated on inodes that actually carry an inline xattr, so legitimate
inodes with i_inline_xattr_size == 0 are still accepted.

Subject: [PATCH 4391/5214] f2fs: avoid unnecessary
 fscrypt_finalize_bounce_page()

fscrypt_finalize_bounce_page() should be called only if we use fs layer
crypto, let's avoid unnecessary fscrypt_finalize_bounce_page() in error
path of f2fs_write_compressed_pages().

BTW, fscrypt_finalize_bounce_page() will check mapping of bounced page
before retrieving original page, so, previously it won't cause any issue
w/ fscrypt_finalize_bounce_page(), but still we'd better avoid coupling
w/ any logic inside fscrypt_finalize_bounce_page().

Subject: [PATCH 4393/5214] f2fs: skip direct I/O iostat context when disabled

F2FS iostat is optional and is disabled by default.  Direct I/O still
allocates and binds a bio_iostat_ctx, updates the submit timestamp, and
replaces bi_end_io for every DIO bio even when sbi->iostat_enable is
false.

The byte accounting calls do not need an extra guard because
f2fs_update_iostat() already checks sbi->iostat_enable.  Only skip the
DIO bio context setup when iostat is disabled.  If iostat is enabled
through sysfs before submission, the existing context allocation and
latency accounting path is still used.

QEMU benchmark on a 1GiB F2FS virtio-blk image, with iostat_enable=0,
4KiB O_DIRECT I/O over a 64MiB file, 50000 iterations per run:

Subject: [PATCH 4395/5214] f2fs: fix to round down start offset of fallocate
 for pin file

Currently, the length of fallocate for pin file is section-aligned to
keep allocated sections from being selected as victims of GC. However,
for the case that the start offset of fallocate is not aligned in
section, the allocated sections can't be fully utilized. It's because a
new section is allocated by f2fs_allocate_pinning_section() after using
blks_per_sec blocks regardless of the start offset. As a result, several
unexpected dirty segments may be created, including blocks assigned to
the pinned file.

To address this issue, let's round down the start offset of fallocate
to the length of section.

The reproducing scenario is as below

chunk=$(((2<<20)+4096)) # 2MB + 4KB
touch test
f2fs_io pinfile set test
f2fs_io fallocate 0 0 $chunk test
f2fs_io fallocate 0 $chunk $chunk test
f2fs_io fallocate 0 $((chunk*2)) $chunk test
f2fs_io fiemap 0 $((chunk*3)) test

Fiemap: offset = 0 len = 12288
    logical addr.    physical addr.   length           flags
0   0000000000000000 000000068c600000 0000000000400000 00001088

are out of range, and NO_BAR (-1) as a negative signed value would slip

epf_ntb->db_count value should be within 1 to MAX_DB_COUNT. Current code

Subject: [PATCH 4403/5214] PCI: endpoint: pci-epf-vntb: Document legacy MSI
 doorbell offset

vntb_epf_peer_db_set() raises an MSI interrupt to notify the RC side of
a doorbell event. pci_epc_raise_irq(..., PCI_IRQ_MSI, interrupt_num)
takes a 1-based MSI interrupt number.

The ntb_hw_epf driver reserves MSI #1 for link events, so doorbells
would naturally start at MSI #2 (doorbell bit 0 -> MSI #2). However,
pci-epf-vntb has historically applied an extra offset and mapped doorbell
bit 0 to MSI #3. This matches the legacy behavior of ntb_hw_epf and has
been preserved since commit e35f56bb0330 ("PCI: endpoint: Support NTB
transfer between RC and EP").

This offset has not surfaced as a functional issue because:

  - ntb_hw_epf typically allocates enough MSI vectors, so the off-by-one
    still hits a valid MSI vector, and

  - ntb_hw_epf does not implement .db_vector_count()/.db_vector_mask(), so
    client drivers such as ntb_transport effectively ignore the vector
    number and schedule all QPs.

Correcting the MSI number would break interoperability with peers
running older kernels.

Document the legacy offset to avoid confusion when enabling
per-db-vector handling.

Subject: [PATCH 4404/5214] PCI: endpoint: pci-epf-vntb: Defer
 pci_epc_raise_irq() out of atomic context

The NTB .peer_db_set() callback may be invoked from atomic context.
pci-epf-vntb currently calls pci_epc_raise_irq() directly, but
pci_epc_raise_irq() may sleep (it takes epc->lock).

Avoid sleeping in atomic context by coalescing doorbell bits into an
atomic64 pending mask and raising MSIs from a work item. Limit the
amount of work per run to avoid monopolizing the workqueue under a
doorbell storm.

Clear stale pending bits before enabling the work item and after disabling
it during cleanup. Also mask requested doorbells against the currently
valid doorbell mask before queueing work, and iterate the pending u64 with
__ffs64() so high doorbell bits are handled correctly.

Subject: [PATCH 4405/5214] PCI: endpoint: pci-epf-vntb: Report 0-based
 doorbell vector via ntb_db_event()

ntb_db_event() expects the vector number to be relative to the first
doorbell vector starting at 0.

pci-epf-vntb reserves vector 0 for link events and uses higher vector
indices for doorbells. By passing the raw slot index to ntb_db_event(),
it effectively assumes that doorbell 0 maps to vector 1.

However, because the host uses a legacy slot layout and writes doorbell
0 into the third slot, doorbell 0 ultimately appears as vector 2 from
the NTB core perspective.

Adjust pci-epf-vntb to:

  - skip the unused second slot, and

  - report doorbells as 0-based vectors (DB#0 -> vector 0).

This change does not introduce a behavioral difference until
.db_vector_count()/.db_vector_mask() are implemented, because without
those callbacks NTB clients effectively ignore the vector number.

Subject: [PATCH 4406/5214] PCI: endpoint: pci-epf-vntb: Reject unusable
 doorbell counts

pci-epf-vntb reserves slot 0 for link events and keeps slot 1 unused for
legacy layout compatibility. A db_count smaller than MIN_DB_COUNT leaves
no usable doorbell slot after those reservations.

Reject such configurations when configuring interrupts.

While at it, move MAX_DB_COUNT next to MIN_DB_COUNT. They are used as a
pair in the range check, and keeping them together makes the valid doorbell
range easier to read.

Subject: [PATCH 4407/5214] PCI: endpoint: pci-epf-vntb: Guard configfs writes
 after EPC attach

db_count controls how many doorbell slots are allocated and exposed. It is
also used by the doorbell mask helpers. After an EPC has been attached,
changing it from configfs can leave runtime paths using a different count
than the one used to set up the doorbell resources.

Reject db_count writes after EPC attach, and reject values outside
MIN_DB_COUNT..MAX_DB_COUNT before attach. Now that MIN_DB_COUNT documents
the usable doorbell floor, use it in the store path too.

While at it, apply the same after-attach guard to the other vNTB configfs
knobs. BAR choices, spad_count, memory-window counts and sizes, and the
virtual PCI IDs are also consumed during bind, so changing them later at
runtime is meaningless and unsafe.

Return -EOPNOTSUPP for after-attach writes. The value itself may be valid,
but changing it in that state is not supported.

Subject: [PATCH 4409/5214] bpf: Preserve pointer spill metadata during
 half-slot cleanup

__clean_func_state() cleans dead stack slots in 4-byte halves. When the
high half of a STACK_SPILL slot is dead and the low half remains live,
cleanup converts the live low half to STACK_MISC or STACK_ZERO and clears
the saved spilled_ptr metadata.

That conversion is safe only for scalar spills. For a pointer spill, this
metadata clear lets a later 32-bit fill from the still-live half avoid the
normal non-scalar register-fill check and be treated as an ordinary scalar
stack read.

Leave non-scalar spill slots intact in this half-live shape. This is
conservative for pruning and preserves the existing
check_stack_read_fixed_off() rejection path for partial fills from pointer
spills.

Subject: [PATCH 4411/5214] sched_ext: Make kernel/sched/ext/ sources
 self-contained for clangd

The sources under kernel/sched/ext/ build as a single translation unit:
build_policy.c includes the source files and headers. An LSP/clangd editor
parses each as a standalone unit, sees no types, and reports a flood of
errors.

Give each header its dependencies and include guard, and have each source
include the headers it uses.

ext.c, arena.c and the ext headers now parse clean standalone. idle.c and
cid.c still reference a few macros and helpers defined in ext.c. The next
patch moves those to shared headers.

Subject: [PATCH 4412/5214] sched_ext: Move shared helpers from ext.c into
 internal.h and cid.h

idle.c and cid.c are included into build_policy.c together with ext.c and
use helpers that ext.c defines. Because the helpers live in ext.c, the two
files can not parse as standalone units and clangd reports errors in them.

Move the helpers to the headers they belong to. The op-dispatch macros and
helpers plus scx_parent() to internal.h, and scx_cpu_arg()/scx_cpu_ret() to
cid.h. No functional change. idle.c and cid.c now parse clean standalone.

Subject: [PATCH 4413/5214] ceph: convert inode flags to named bit positions
 and atomic bitops

Define named bit-position constants for all CEPH_I_* inode flags and
derive the bitmask values from them.  This gives every flag a named
_BIT constant usable with the test_bit/set_bit/clear_bit family.
The intentionally unused bit position 1 is documented inline.

Convert all flag modifications to use atomic bitops (set_bit,
clear_bit, test_and_clear_bit).  The previous code mixed lockless
atomic ops on some flags (ERROR_WRITE, ODIRECT) with non-atomic
read-modify-write (|= / &= ~) on other flags sharing the same
unsigned long.  A concurrent non-atomic RMW can clobber an
adjacent lockless atomic update -- for example, a lockless
clear_bit(ERROR_WRITE) could be silently resurrected by a
concurrent ci->i_ceph_flags |= CEPH_I_FLUSH under the spinlock.
Using atomic bitops for all modifications eliminates this class
of race entirely.

Flags whose only users are now the _BIT form (ERROR_WRITE,
ASYNC_CHECK_CAPS) have their old mask defines removed to document
that callers must use the _BIT constant with the set_bit/test_bit
family.  ERROR_FILELOCK and SHUTDOWN retain their mask defines
because they are still used via bitmask tests in lockless readers
(ceph_inode_is_shutdown, reconnect_caps_cb).

The direct assignment in ceph_finish_async_create() is converted
from i_ceph_flags = CEPH_I_ASYNC_CREATE to set_bit().  This
inode is I_NEW at this point -- still invisible to other threads
and guaranteed to have zero flags from alloc_inode -- so either
form is safe, but set_bit() keeps the conversion uniform.

Subject: [PATCH 4414/5214] ceph: use proper endian conversion for flock_len in
 reconnect

Replace the __force __le32 cast with cpu_to_le32() for the flock_len field
in reconnect_caps_cb(). The old code used a type-system bypass to silence
sparse; the new form uses the proper endian conversion macro.

Also switch from a raw bitmask test against i_ceph_flags to test_bit() on
the named CEPH_I_ERROR_FILELOCK_BIT, which is the correct accessor for the
unsigned long flags field after the bit-position conversion.

Remove the now-unused CEPH_I_ERROR_FILELOCK mask define since all callers
use the _BIT form with test_bit/set_bit/clear_bit.

Subject: [PATCH 4415/5214] ceph: harden send_mds_reconnect and handle
 active-MDS peer reset

Change send_mds_reconnect() to return an error code so callers can detect
and report reconnect failures instead of silently ignoring them. Add early
bailout checks for sessions that are already closed, rejected, or
unregistered, which avoids sending reconnect messages for sessions that
can no longer be recovered.

The early -ESTALE and -ENOENT bailouts use a separate fail_return label
that skips the pr_err_client diagnostic, since these codes indicate
expected concurrent-teardown races rather than genuine reconnect build
failures.

Move the "reconnect start" log after the early-bailout checks so it
only appears for sessions that actually proceed with reconnect.

Save the prior session state before transitioning to RECONNECTING,
and restore it in the failure path.  Without this, a transient
build or encoding failure (-ENOMEM, -ENOSPC) strands the session
in RECONNECTING indefinitely because check_new_map() only retries
sessions in RESTARTING state.

Rewrite mds_peer_reset() to handle the case where the MDS is past its
RECONNECT phase (i.e. active). An active MDS rejects CLIENT_RECONNECT
messages because it only accepts them during its own RECONNECT window
after restart. Previously, the client would send a doomed reconnect
that the MDS would reject or ignore. Now, the client tears the session
down locally and lets new requests re-open a fresh session, which is
the correct recovery for this scenario. The RECONNECTING state is
handled on the same teardown path, since the MDS will reject reconnect
attempts from an active client regardless of the session's local state.

Add explicit cases for CLOSED and REJECTED session states in
mds_peer_reset() since these are terminal states where a connection
drop is expected behavior.

The session teardown path in mds_peer_reset() follows the established
drop-and-reacquire locking pattern from check_new_map(): take
mdsc->mutex for session unregistration, release it, then take s->s_mutex
separately for cleanup. This avoids introducing a new simultaneous lock
nesting pattern.

Log reconnect failures from check_new_map() and mds_peer_reset() at
pr_warn level rather than pr_err, since return codes like -ESTALE
(closed/rejected session) and -ENOENT (unregistered session) are
expected during concurrent teardown. Log dropped messages for
unregistered sessions via doutc() (dynamic debug) rather than
pr_info, as post-reset message arrival is routine and does not
warrant unconditional logging.

Subject: [PATCH 4416/5214] ceph: add diagnostic timeout loop to
 wait_caps_flush()

Convert wait_caps_flush() from a silent indefinite wait into a diagnostic
wait loop that periodically dumps pending cap flush state.

The underlying wait semantics remain intact: callers still wait until the
requested cap flushes complete. The difference is that long stalls now
produce actionable diagnostics instead of looking like a silent hang.

CEPH_CAP_FLUSH_MAX_DUMP_ENTRIES limits the number of entries
emitted per diagnostic dump, and CEPH_CAP_FLUSH_MAX_DUMP_ITERS
limits the number of timed diagnostic dumps before the wait
continues silently.  When more entries exist than the per-dump
limit, a truncation count is reported.  When the dump iteration
limit is reached, a final suppression message is emitted so the
transition to silence is explicit.

The diagnostic dump collects flush entry data under cap_dirty_lock into
a bounded on-stack array, then prints after releasing the lock.  This
avoids holding the spinlock across printk calls.

A null cf->ci on the global flush list indicates a bug since all
cap_flush entries are initialized with a valid ci before being added.
Signal this with WARN_ON_ONCE while still printing enough context for
debugging.

READ_ONCE is used for the i_last_cap_flush_ack field, which is read
outside the inode lock domain. Flush tids are monotonically increasing
and acks are processed in order under i_ceph_lock, so the latest ack
tid is always the most recently written value.

Add a ci pointer to struct ceph_cap_flush so that the diagnostic
dump can identify which inode each pending flush belongs to.  The
new i_last_cap_flush_ack field tracks the latest acknowledged flush
tid per inode for diagnostic correlation.

This improves reset-drain observability and is also useful for
existing sync and writeback troubleshooting paths.

Subject: [PATCH 4417/5214] ceph: add client reset state machine and session
 teardown

Add the client-side reset state machine, request gating, and manual
session teardown implementation.

Manual reset is an operator-triggered escape hatch for client/MDS
stalemates in which caps, locks, or unsafe metadata state stop making
forward progress.  The reset blocks new metadata work, attempts a
bounded best-effort drain of dirty client state while sessions are
still alive, and finally asks the MDS to close sessions before tearing
local session state down directly.

The reset state machine tracks four phases: IDLE -> QUIESCING ->
DRAINING -> TEARDOWN -> IDLE.  QUIESCING is set synchronously by
schedule_reset() before the workqueue item is dispatched, so that new
metadata requests and file-lock acquisitions are gated immediately --
even before the work function begins running.  All non-IDLE phases
block callers on blocked_wq, preventing races with session teardown.

The drain phase flushes mdlog state, dirty caps, and pending cap
releases for a bounded interval.  State that still cannot make progress
within that interval is discarded during teardown, which is the point
of the reset: break the stalemate and allow fresh sessions to rebuild
clean state.

The session teardown follows the established check_new_map()
forced-close pattern: unregister sessions under mdsc->mutex, then clean
up caps and requests under s->s_mutex.  Reconnect is not attempted
because the MDS only accepts reconnects during its own RECONNECT phase
after restart, not from an active client.

Blocked callers are released when reset completes and observe the final
result via -EAGAIN (reset failed) or 0 (success).  Internal work-function
errors such as -ENOMEM are not propagated to unrelated callers like
open() or flock(); the detailed error remains in debugfs and
tracepoints.

The work function checks st->shutdown before each phase transition
(DRAINING, TEARDOWN) so that a concurrent ceph_mdsc_destroy() is not
overwritten.  If destroy already took ownership, the work function
releases session references and returns without touching the state.

The timeout calculation for blocked-request waiters uses max_t() to
prevent jiffies underflow when the deadline has already passed.

The close-grace sleep before teardown is a best-effort nudge to let
queued REQUEST_CLOSE messages egress; it is not a correctness
requirement since the MDS still has session_autoclose as a fallback.

The destroy path marks reset as failed and wakes blocked waiters before
cancel_work_sync() so unmount does not stall.

Subject: [PATCH 4418/5214] ceph: add manual reset debugfs control and
 tracepoints

Add the debugfs and trace plumbing used to trigger and observe
manual client reset.

The reset interface exposes a trigger file for operator-initiated
reset and a status file for tracking the most recent run.  The
tracepoints record scheduling, completion, and blocked caller
behavior so reset progress can be diagnosed from the client side.

debugfs layout under /sys/kernel/debug/ceph/<client>/reset/:
  trigger - write to initiate a manual reset
  status  - read to see the most recent reset result

The reset directory is cleaned up via debugfs_remove_recursive()
on the parent, so individual file dentries are not stored.

Tracepoints:
  ceph_client_reset_schedule  - reset queued
  ceph_client_reset_complete  - reset finished (success or failure)
  ceph_client_reset_blocked   - caller blocked waiting for reset
  ceph_client_reset_unblocked - caller unblocked after reset

All tracepoints use a null-safe access for monc.auth->global_id
to guard against early-init or late-teardown edge cases.

Subject: [PATCH 4419/5214] ice: fix FDIR CTRL VSI resource leak in
 ice_reset_all_vfs()

Resetting all VFs causes resource leak on VFs with FDIR filters
enabled as CTRL VSIs are only invalidated and not freed. Fix by using
ice_vf_ctrl_vsi_release() instead of ice_vf_ctrl_invalidate_vsi() which
aligns behavior with the ice_reset_vf() function.

Reproduction:
  echo 1 > /sys/class/net/$pf/device/sriov_numvfs
  ethtool -N $vf flow-type ether proto 0x9000 action 0
  echo 1 > /sys/class/net/$pf/device/reset

Subject: [PATCH 4420/5214] ice: fix AQ error code comparison in
 ice_set_pauseparam()

Fix unreachable code: the conditionals in ice_set_pauseparam() used
the bitwise-AND operator suggesting aq_failures is a bitmap, but it
is actually an enum, making the third condition logically unreachable.

Replace the if-else ladder with a switch statement.  Also move the
aq_failures initialization to the variable declaration and remove the
redundant zeroing from ice_set_fc().

Subject: [PATCH 4421/5214] ice: fix ice_init_link() error return preventing
 probe

ice_init_link() can return an error status from ice_update_link_info()
or ice_init_phy_user_cfg(), causing probe to fail.

An incorrect NVM update procedure can result in link/PHY errors, and
the recommended resolution is to update the NVM using the correct
procedure. If the driver fails probe due to link errors, the user
cannot update the NVM to recover. The link/PHY errors logged are
non-fatal: they are already annotated as 'not a fatal error if this
fails'.

Since none of the errors inside ice_init_link() should prevent probe
from completing, convert it to void and remove the error check in the
caller. All failures are already logged; callers have no meaningful
recovery path for link init errors.

Subject: [PATCH 4423/5214] io_uring/memmap: bound io_pin_pages() by page array
 byte size

io_pin_pages() checks that nr_pages does not exceed INT_MAX, then
allocates a struct page * array of nr_pages entries. kvmalloc() limits
allocations to INT_MAX bytes, but the check counts pages, not bytes.
On 64-bit each entry is 8 bytes, so the array hits the INT_MAX byte
limit at INT_MAX / sizeof(struct page *) pages, well before the page
count check fires.

Since commit b4e41050b212 ("io_uring/rsrc: raise registered buffer 1GB
limit") raised the per-buffer cap to 1TB, a buffer near that cap maps
~2^28 pages, making the array allocation exceed INT_MAX bytes. This
passes the page count check, reaches kvmalloc(), and triggers the
WARN_ON_ONCE() for oversized allocations in __kvmalloc_node_noprof().

Check nr_pages against INT_MAX / sizeof(struct page *) so the buffer is
rejected with -EOVERFLOW before the allocation is attempted.

Subject: [PATCH 4424/5214] rtc: isl1208: Balance enable_irq_wake() with
 disable_irq_wake() on cleanup

isl1208_setup_irq() calls enable_irq_wake() after a successful
IRQ request, but the driver has no remove path that balances it.
The driver is devm-only, so on unbind devm releases the IRQ -
but enable_irq_wake() is not undone by IRQ release, so the wake
count for that IRQ stays incremented.

Each rebind therefore leaks one wake reference; the leak doubles
for the chip variant that has a separate evdet IRQ, since
isl1208_setup_irq() is then called twice during probe.

Register a devm action that calls disable_irq_wake() per IRQ.
While at it, check enable_irq_wake()'s return value:
on failure, propagate the error rather than silently registering
a disable action for an IRQ whose wake state was never enabled.

Subject: [PATCH 4425/5214] ice: dpll: set pointers to NULL after kfree in
 ice_dpll_deinit_info

ice_dpll_deinit_info() calls kfree() on several pf->dplls fields
(inputs, outputs, eec.input_prio, pps.input_prio) but does not set
the pointers to NULL afterward. This leaves dangling pointers in the
pf->dplls structure.

While not currently exploitable through existing code paths, this is
unsafe because:

1. If ice_dpll_init_info() is called again after a deinit (e.g. during
   driver recovery), and a subsequent allocation within init fails, the
   error path will jump to deinit_info and call ice_dpll_deinit_info()
   again. Since some pointers still hold the old freed addresses, this
   would result in a double-free.

2. Any future code that checks these pointers before use or after free
   would be unprotected against use-after-free.

Follow the common kernel convention of setting pointers to NULL after
kfree() so that:
- kfree(NULL) is a safe no-op, preventing double-free
- NULL checks on these pointers become meaningful

This is a preparatory fix for a subsequent patch that routes additional
error paths in ice_dpll_init_info() to the deinit_info label.

Several error return paths in ice_dpll_init_info() directly return
without freeing previously allocated resources, causing memory leaks:

- When de->input_prio allocation fails, d->inputs is leaked
- When dp->input_prio allocation fails, d->inputs and de->input_prio
  are leaked
- When ice_get_cgu_rclk_pin_info() fails, all previously allocated
  inputs/outputs/input_prio are leaked
- When ice_dpll_init_pins_info(RCLK_INPUT) fails, same resources
  are leaked

Fix this by jumping to the deinit_info label which properly calls
ice_dpll_deinit_info() to free all allocated resources.

Subject: [PATCH 4428/5214] e1000e: Reconfigure PLL clock gate timeout and
 re-enable K1 on Meteor Lake

Commit 3c7bf5af21960 ("e1000e: Introduce private flag to disable K1")
disabled K1 by default on Meteor Lake and newer systems due to packet
loss observed on various platforms. However, disabling K1 caused an
increase in power consumption.

To mitigate this, reconfigure the PLL clock gate value so that K1 can
remain enabled without incurring the additional power consumption.
Re-enable K1 by default, but keep the private flag to support disabling
it via ethtool. Additionally, introduce a DMI quirk table, so that K1 may
be disabled by default on known problematic systems. Currently, this
includes the Dell Pro 16 Plus, where the issue has been reported to persist

Subject: [PATCH 4430/5214] nbd: don't warn when reclassifying a busy socket
 lock

nbd_reclassify_socket() warns via WARN_ON_ONCE() if the socket lock is
held at the point of reclassification. That assertion was copied from
nvme-tcp, where the socket is created internally by the kernel
(sock_create_kern()) and is never visible to user space, so the lock
is guaranteed to be free.

NBD is different: the socket is looked up from a user-supplied fd in
nbd_get_socket(), and user space retains that fd. A concurrent syscall
on the same socket (or softirq processing taking bh_lock_sock() on a
connected TCP socket) can legitimately hold the lock at the instant
NBD reclassifies it. sock_allow_reclassification() then returns false
and the WARN_ON_ONCE() fires, which turns into a crash under
panic_on_warn. This is reachable by simply racing NBD_CMD_CONNECT
against socket activity on the same fd, as reported by syzbot.

Hitting a held lock here is expected for an externally owned socket and
is not a kernel bug, so skip reclassification silently instead of
warning. Reclassification is a lockdep-only annotation, so skipping it
in the rare racing case is harmless.

Subject: [PATCH 4431/5214] block, bfq: protect async queue reset with blkcg
 locks

Writing 0 to BFQ's low_latency attribute ends weight raising for active,
idle and async queues. The async cgroup path walks q->blkg_list, converts
each blkg to BFQ policy data and then reads bfqg->async_bfqq and
bfqg->async_idle_bfqq.

That walk was protected only by bfqd->lock. blkcg release work is
serialized by q->blkcg_mutex and q->queue_lock instead, and
blkg_free_workfn() can call BFQ's pd_free_fn before it removes
blkg->q_node from q->blkg_list. A low_latency reset can therefore still
find the blkg on the queue list after the BFQ policy data has been freed.

The buggy scenario involves two paths, with each column showing the order
within that path:

BFQ low_latency reset:              blkcg blkg release work:
1. bfq_low_latency_store()          1. blkg_free_workfn() takes
   calls bfq_end_wr().                 q->blkcg_mutex.
2. bfq_end_wr_async() walks         2. BFQ pd_free_fn drops the
   q->blkg_list.                       final bfq_group reference.
3. blkg_to_bfqg() returns           3. blkg->q_node remains on
   the stale policy data.              q->blkg_list until list_del_init().
4. bfq_end_wr_async_queues()
   reads async queue fields.

Fix this by taking q->blkcg_mutex and q->queue_lock around the
q->blkg_list walk, then taking bfqd->lock before touching BFQ async
queues. The mutex serializes against policy-data free and queue_lock
stabilizes the list. Move the async reset out of bfq_end_wr()'s existing
bfqd->lock critical section so the lock order matches blkcg policy
callbacks.

Subject: [PATCH 4432/5214] blk-cgroup: fix UAF in __blkcg_rstat_flush()

When multiple blkgs in the same blkcg are released concurrently,
a use-after-free can occur. The race happens when one blkg's
__blkcg_rstat_flush() removes another blkg's iostat entries via
llist_del_all(). The second blkg sees an empty list and proceeds
to free itself while the first is still iterating over its entries.

Move the flush from __blkg_release() (RCU callback) to blkg_release()
(before call_rcu). This ensures the RCU grace period waits for any
concurrent flush's rcu_read_lock() section to complete before freeing.

	        list_del_init(&blkg->q_node)

As a result, a blkg can still be reachable through q->blkg_list while
its ->blkcg has already been freed.

[Fix]
Fix this by deferring the blkcg css_put() until after the blkg has been
unlinked from q->blkg_list in blkg_free_workfn(). This ensures that the
blkcg outlives every blkg still reachable through q->blkg_list, so any
iterator holding q->queue_lock is guaranteed to observe a valid
blkg->blkcg.

While at it, move css_tryget_online() from blkg_create() into blkg_alloc()
so that the css reference is owned by the alloc/free pair rather than
straddling layers:
blkg_alloc()  <-> blkg_free()
blkg_create() <-> blkg_destroy()

Subject: [PATCH 4434/5214] rtc: interface: Add rtc_read_next_alarm() to read
 next expiring timer

Add a new function rtc_read_next_alarm() that reads the next expiring
alarm from the RTC timerqueue. This is different from rtc_read_alarm(),
which only reads the aie_timer.

The wakealarm sysfs file programs the rtc->aie_timer, whereas the
alarmtimer suspend routine programs its own timer into the RTC timerqueue.
Both timers end up in the RTC's timerqueue, and the first expiring timer
is what gets armed in the hardware.

This new function allows code to query which alarm will actually fire
next, regardless of which subsystem programmed it. This is needed by
platform code that needs to program secondary timers based on the
actual next wakeup time.

Subject: [PATCH 4436/5214] rtc: msc313: fix NULL deref in shared IRQ handler
 at probe

msc313_rtc_probe() calls devm_request_irq() with IRQF_SHARED and
&pdev->dev as the cookie, but platform_set_drvdata() is only called
later after the clock setup. With a shared IRQ line, another device
on the same line can trigger the handler in that window. The
handler does dev_get_drvdata() on the cookie, gets NULL, and
dereferences priv->rtc_base in interrupt context.

Pass priv as the cookie directly so the handler reads it from
dev_id without the lookup, removing the dependency on probe order.

Fixes: be7d9c9161b9 ("rtc: Add support for the MSTAR MSC313 RTC")

Subject: [PATCH 4440/5214] rtc: mv: add suspend/resume support for wakeup

Add PM suspend/resume callbacks to enable/disable IRQ wake for the
RTC alarm interrupt. This allows the RTC alarm to wake the system
from STR (e.g. via rtcwake -m mem -s N).

Without this, the RTC IRQ is masked during suspend by the MPIC's
IRQCHIP_MASK_ON_SUSPEND behavior, preventing alarm-based wakeup.

Subject: [PATCH 4441/5214] bpf: Guard conntrack opts error writes

The conntrack lookup and allocation kfuncs take an opts pointer
together with an opts__sz argument. The verifier checks only the memory
range described by opts__sz, but the wrappers unconditionally write
opts->error whenever the internal lookup or allocation helper returns an
error.

For an invalid size smaller than the end of opts->error, that write can
land outside the verifier-checked range. Keep returning NULL for invalid
arguments, but only report the error through opts->error when the
supplied size includes the field.

This preserves error reporting for the supported 12-byte and 16-byte
layouts, and for other invalid sizes that still include opts->error.

Subject: [PATCH 4442/5214] selftests/bpf: Cover small conntrack opts error
 writes

Add a conntrack kfunc regression check for opts__sz values that do not
cover opts->error. The BPF program initializes opts->error with a guard
value, calls the lookup and allocation kfuncs with opts__sz set to
sizeof(opts->netns_id), and verifies that the guard is still intact
after the kfunc returns NULL.

Without the conntrack wrapper guard, the kfunc error path overwrites
that guard with -EINVAL even though the verifier checked only the first
four bytes of the options object.

Subject: [PATCH 4444/5214] bpf: Reset register bounds before narrowing retval
 range in check_mem_access()

When the BPF verifier processes a context load of an LSM hook return
value, it calls __mark_reg_s32_range() to narrow the register to the
hook's valid range. However, __mark_reg_s32_range() intersects the new
range with the register's existing bounds using max_t()/min_t() rather
than replacing them.

If the destination register carries stale bounds from a prior instruction
(e.g. BPF_MOV64_IMM), the intersection can produce a range narrower than
reality. The verifier then believes it knows the register's exact value,
while at runtime the actual hook return value is loaded, creating a
verifier/runtime mismatch that can be used to bypass BPF memory safety
checks.

The else branch already calls mark_reg_unknown() to reset register state
before any narrowing. Apply the same reset in the is_retval path so
stale bounds are cleared before __mark_reg_s32_range() intersects.

 retval context load

Add a verifier test that catches the stale-bounds issue fixed in the
previous patch. The test sets r6 = 0 to create known bounds, then loads
the LSM hook return value into r6 from the context. Without the fix,
the verifier intersects the retval range with the stale bounds and
incorrectly narrows r6 to a single value, pruning the fall-through
branch as dead code and missing the div-by-zero.

Subject: [PATCH 4446/5214] net: ethernet: ti: icssg: guard PA stat lookups

icssg_ndo_get_stats64() unconditionally calls emac_get_stat_by_name()
with FW PA stat names regardless of whether the PA stats block is
present on the hardware.  emac_get_stat_by_name() already guards the
PA stats lookup with `if (emac->prueth->pa_stats)`; when that pointer
is NULL the lookup falls through to netdev_err() and returns -EINVAL.
Because ndo_get_stats64 is polled regularly by the networking stack
this produces thousands of log entries of the form:

  icssg-prueth icssg1-eth end0: Invalid stats FW_RX_ERROR

A secondary consequence is that the int(-EINVAL) return value is
implicitly widened to a near-ULLONG_MAX unsigned value when accumulated
into the __u64 fields of rtnl_link_stats64, silently corrupting the
rx_errors, rx_dropped and tx_dropped counters reported by `ip -s link`.

Every other PA-aware code path in the driver is already guarded with
the same `if (emac->prueth->pa_stats)` check.  Apply the same guard
here.

Subject: [PATCH 4447/5214] ksmbd: track the connection owning a byte-range
 lock

SMB2_LOCK adds each granted byte-range lock to both the file lock list
and the lock list of the connection which handled the request.  The
final close and durable handle paths, however, remove the connection
list entry while holding fp->conn->llist_lock.

With SMB3 multichannel, the connection handling the LOCK request can be
different from the connection which opened the file.  The entry can
therefore be removed under a different spinlock from the one protecting
the list it belongs to.  A concurrent traversal can then access freed
struct ksmbd_lock and struct file_lock objects.

Record the connection owning each lock's clist entry and hold a
reference to it while the entry is linked.  Use that connection and its
llist_lock for unlock, rollback, close, and durable preserve.  Durable
reconnect assigns the new connection as the owner when publishing the
locks again.

Fixes: f5a544e3bab7 ("ksmbd: add support for SMB3 multichannel")

Validate SMB2 lease context lengths, requested lease state bits, and v2
flags before using the context. Return errors via ERR_PTR so CREATE can
distinguish a missing lease context from a malformed one.

Also ignore lease v2 contexts for SMB 2.1, where they are not valid.

MS-SMB2 defines the lease table lookup key as Connection.ClientGuid.
Use the connection ClientGUID consistently when checking for same-client
leases and duplicate lease keys.

Also preserve directory and parent lease metadata when copying an existing
lease state to a new open.

Subject: [PATCH 4451/5214] ksmbd: fix lease break and ack state handling

Do not skip valid lease states containing WRITE_CACHING when breaking
level-II/read leases for writes and truncates.

Handle lease break acknowledgments according to the SMB2 rule that the
acknowledged state must be a subset of the server's break target. Apply
the acknowledged state directly and keep the break pending on failed ACKs.

Subject: [PATCH 4452/5214] ksmbd: clean up lease response flags and directory
 leases

Do not echo reserved v1 lease flags back to clients. For lease v2
responses, only return BREAK_IN_PROGRESS and PARENT_LEASE_KEY_SET when
they are meaningful, and preserve the parent lease key in the response.

Allow directory leases whenever the request is a valid lease v2 request,
and initialize v2 lease epochs from the first server-granted state change.

Subject: [PATCH 4453/5214] ksmbd: share SMB2 lease state across opens

Model SMB2 leases as per-client/per-key objects instead of keeping a
separate lease copy in every oplock_info. The lease table now stores
lease objects and each lease tracks the opens that reference it.

This makes same ClientGuid/LeaseKey opens observe a single lease state,
so lease upgrades, breaks, ACKs, and close teardown do not diverge across
per-open copies. Keep one reference for the lease table entry and one
reference for each open, and remove the table entry when the last open is
detached.

Update lease break ACK handling to refresh all open oplock levels from
the shared lease state.

Subject: [PATCH 4454/5214] ksmbd: align SMB2 oplock break ack handling

Handle SMB2 oplock break acknowledgments according to the server-side
validation rules in MS-SMB2.

Return STATUS_INVALID_DEVICE_STATE when an ACK arrives while the open is
not breaking, reject SMB2_OPLOCK_LEVEL_LEASE with
STATUS_INVALID_PARAMETER, allow BATCH acknowledgments to EXCLUSIVE, and
make invalid ACK levels fail with STATUS_INVALID_OPLOCK_PROTOCOL after
lowering the oplock to NONE.

Update the successful response from the final granted oplock level instead
of relying on the oplock transition helpers, which could turn invalid ACKs
into successful responses.

Subject: [PATCH 4455/5214] ksmbd: treat unnamed DATA stream as base file

The SMB path suffix :: names the unnamed data stream of the base
file, not an alternate data stream backed by a DosStream xattr.

Canonicalize an empty stream name with an explicit  type to a NULL
stream name after parsing. This keeps the base filename produced by
strsep() and lets open continue through the normal base-file path instead
of looking for a non-existent empty stream xattr.

Subject: [PATCH 4456/5214] ksmbd: compute lease break-in-progress flag on
 response

SMB2_LEASE_FLAG_BREAK_IN_PROGRESS is a transient create response flag,
not persistent lease state.

Do not store the flag in lease->flags when a same-key open is granted
during a pending break. Instead, derive it from lease opens that are still
waiting for a break ACK while building the lease create response, and keep
lease->flags for persistent lease flags such as the parent lease key.

This clears the flag naturally after the break ACK completes and fixes
reopen responses that report BREAK_IN_PROGRESS after the lease is no
longer breaking.

Subject: [PATCH 4457/5214] ksmbd: chain pending lease breaks before waking
 waiters

A pending open can require more than one lease break before the existing
lease becomes compatible with the operation that triggered the break.
smb2.lease.breaking3 expects the server to hold the pending normal open
through RWH->RH and RH->R, while a later overwrite waiter must not
collapse that second break directly to RH->NONE.

Keep pending_break held for lease breaks until the current triggering
operation is compatible with the lease state. Snapshot the truncate request
per oplock_break() call so another waiter cannot overwrite the state of
the active break.

Use the requested oplock level when deciding whether to chain another
break. A second lease open only needs RWH->RH, while a normal none-oplock
open can continue down to R and then NONE.

For non-truncating metadata operations, break leases only down to read
caching. Operations such as delete-on-close need to drop handle caching,
but should not send a second R->NONE break after the client acknowledges
RH->R.

Also send STATUS_PENDING for levelII/read-lease break waiters. An async
SMB2 create becomes cancelable only after the server sends
an NT_STATUS_PENDING interim response. A waiter that blocks behind an
already active lease break must receive the interim response before
sleeping on pending_break, otherwise the client can process a later lease
break while the create request is still not marked pending.

Avoid duplicate interim responses when an overwrite first breaks a write
oplock and then scans levelII/read leases.

Subject: [PATCH 4458/5214] ksmbd: do not wait for RH lease break ack on
 overwrite

smb2.lease.breaking4 expects an overwrite against an RH lease to send
RH->NONE lease break notification but complete the triggering create
without waiting for the break ack.

Keep the lease in break-in-progress state until the client eventually
acknowledges the downgrade, but do not hold the overwrite request behind
that ack.

Subject: [PATCH 4459/5214] ksmbd: honor SMB2 v2 lease epochs

v2 lease responses should continue from the client supplied epoch.
Initialize a new v2 lease from the requested epoch plus one so create
responses match the epoch returned by Windows and expected by smbtorture.

For a single chained break sequence, increment the epoch only for the first
break notification. Follow-up breaks such as RH->R and R->NONE in
smb2.lease.v2_breaking3 reuse the same epoch.

Record when a waiter slept behind pending_break and let the later
truncate/open overwrite break consume that marker to reuse the current
epoch instead of assigning a new one.

Do not increment the epoch when a same-client, same-key create asks for
the already granted RH state. The epoch changes only when the granted lease
state changes.

Subject: [PATCH 4460/5214] ksmbd: break RH leases before delete-on-close

The delete paths only marked the opened file delete pending or
delete-on-close.  When another client still held a read/handle lease, no
lease break was sent before the delete state changed.

smb2.lease.unlink uses a create request with FILE_DELETE_ON_CLOSE and
expects the second client's unlink to break the first client's RH lease to
R with ACK_REQUIRED set.  SetInfo(FileDispositionInformation) has the same
lease-breaking requirement.

Break level-II/read-handle leases before setting delete pending or
delete-on-close so clients are notified before the file is removed.

Subject: [PATCH 4461/5214] ksmbd: route v2 lease breaks on the client lease
 channel

v2 leases are scoped by ClientGuid.  When the same client uses multiple
connections, smbtorture expects lease break notifications to be sent on
the connection associated with the client lease table, not necessarily
on the connection that owns the individual open being broken.

Keep a referenced connection in the lease table and use it for v2 lease
break notifications while it is still active.  Fall back to the open's
connection if the table connection is being released.

Subject: [PATCH 4462/5214] ksmbd: keep common response iovecs in the work item

Most SMB responses need no more than four kvec entries, but every work
item currently allocates a separate four-entry array and frees it after
the response is sent.

Embed the common array in struct ksmbd_work and allocate a larger array
only when a response exceeds the inline capacity. This removes one
allocation and one free from the common request path while preserving
support for larger compound and read responses.

Subject: [PATCH 4463/5214] ksmbd: fix use-after-free of conn->preauth_info in
 concurrent SMB2 NEGOTIATE

conn->preauth_info is shared connection state (struct
preauth_integrity_info, kmalloc-96) that is allocated and freed by the
SMB2 NEGOTIATE handler and read by the response send path.

smb2_handle_negotiate() allocates conn->preauth_info, and on a
deassemble_neg_contexts() failure kfrees it and sets it to NULL. Both the
allocation and the free/NULL happen under ksmbd_conn_lock(conn) (the
connection srv_mutex), which is held across the whole handler body.

The response send path smb3_preauth_hash_rsp(), called from the send:
block of __handle_ksmbd_work(), reads conn->preauth_info and dereferences
conn->preauth_info->Preauth_HashValue (via
ksmbd_gen_preauth_integrity_hash()) without taking conn_lock. When a
client drives two SMB2 NEGOTIATE requests on the same connection, one
worker can free conn->preauth_info on the failing-negotiate path while a
concurrent send-path worker is reading it, producing a slab
use-after-free read (KASAN-confirmed).

The send-path read tested conn->preauth_info for NULL but raced with the
free that occurs between the NULL check and the dereference, so the NULL
guard alone does not close the window.

Serialize the NEGOTIATE-branch read in smb3_preauth_hash_rsp() under
ksmbd_conn_lock(conn) and re-check conn->preauth_info inside the lock.
Because the negotiate handler holds conn_lock across its kfree + NULL
assignment, a reader that also takes conn_lock either runs fully before
the allocation or fully after the NULL store, and can never observe the
freed-but-not-yet-NULLed pointer. ksmbd_gen_preauth_integrity_hash()
takes no locks itself (it only computes a SHA-512 over the buffer), so
no lock-ordering inversion is introduced, and conn_lock is a sleepable
mutex which is safe on this send path (it already performs network I/O).

Subject: [PATCH 4464/5214] ksmbd: handle missing create contexts for lease
 opens

smb2_find_context_vals() assumes that callers only search create
contexts when the SMB2 CREATE request contains a non-empty create context
area. That is not always true. a client can send RequestedOplockLevel set
to SMB2_OPLOCK_LEVEL_LEASE without a lease create context.

In that case parse_lease_state() searches for a lease context and
smb2_find_context_vals() starts parsing from offset 0 with length 0,
returning -EINVAL. This makes the open fail with STATUS_INVALID_PARAMETER.
The smbtorture smb2.lease.duplicate_open test hits this while creating
a second file without a lease request.

Return NULL when the request has no create context area so the missing
context is treated the same as any other absent create context.  The open
then continues without granting a lease.

Subject: [PATCH 4465/5214] ksmbd: supersede disconnected delete-on-close
 durable handle

A durable handle opened with FILE_DELETE_ON_CLOSE is preserved across a
disconnect so it can be reclaimed by a durable reconnect.
smb2.durable-open.delete_on_close2 disconnects such a handle and then
reconnects it, expecting the reconnect to succeed.

When the client does not reconnect but instead opens the same name with a
new delete-on-close create, the preserved handle keeps the file present
with delete-on-close set. ksmbd then rejects the new open with
STATUS_ACCESS_DENIED on the file_present + FILE_DELETE_ON_CLOSE +
OPEN_IF/OVERWRITE_IF path. smb2.durable-open.delete_on_close1 expects this
open to create a fresh, empty file instead, i.e. the disconnected handle's
delete-on-close must take effect first.

Add ksmbd_close_disconnected_durable_delete_on_close(), which closes
disconnected (conn == NULL) durable handles that keep a delete-on-close
file present. The final close promotes S_DEL_ON_CLS to S_DEL_PENDING and
unlinks the file, so a re-resolved path is absent and the new open creates
it fresh. Call it from smb2_open() before the delete-on-close conflict
check, only for the conflicting open shapes. A live (connected) handle
still keeps the file and blocks the open as before.

Subject: [PATCH 4466/5214] ksmbd: invalidate durable handles on oplock break

When a durable handle is preserved after a disconnect, its oplock state
can still block later opens. If another client opens the same file and
the preserved oplock or lease has to be broken, the old durable handle
must no longer be reconnectable after the break cannot be acknowledged.

ksmbd was treating a missing connection, or an oplock break timeout, as a
successful break only by downgrading the oplock state.  The old durable
handle remained reconnectable, so a later durable reconnect for that
stale handle could succeed.

The open path can also see a detached durable handle before the break
notification helpers fully dispose of it. Invalidate such a preserved
durable handle directly when a competing open has to break its batch or
exclusive oplock, while leaving ordinary durable reconnects without a
competing open untouched.

If the old handle still reaches the reconnect path, reject it when the
same inode already has another active open. This matches the
smb2.durable-open.open2-lease/open2-oplock sequence where a later open
replaces the disconnected durable owner and the stale first handle must
not be reclaimed.

Also, reconnect lookup used only the persistent id. A new durable open
can get a persistent id that matches the stale reconnect request after
the old durable state is invalidated. Preserve the disconnected
handle's old volatile id and require durable reconnect contexts to match
it, so a stale reconnect cannot attach to a different durable open.

Windows allows the later open to proceed and rejects the old reconnect
with STATUS_OBJECT_NAME_NOT_FOUND. The smbtorture
smb2.durable-open.oplock test covers this case.

Subject: [PATCH 4467/5214] ksmbd: fix durable reconnect context parsing

SMB2 create context DataLength describes only the create context data
payload. It does not include the create context header, name field, or
any local padding that exists in ksmbd's helper structures.

ksmbd validated durable reconnect contexts by comparing
DataOffset + DataLength against sizeof the whole helper structure. This
rejects a valid durable v2 reconnect context because the wire DH2C data
is 36 bytes while struct create_durable_handle_reconnect_v2 contains an
extra four byte pad.

Validate the durable context payload length against the corresponding
payload member instead. Also keep the reconnect context authoritative
when a later durable request context is present, matching the existing
durable v1 reconnect behavior.

This fixes smbtorture smb2.durable-v2-open.durable-v2-setinfo, where
the durable v2 reconnect after SET_INFO was rejected with
STATUS_INVALID_PARAMETER.

Subject: [PATCH 4468/5214] ksmbd: handle durable v2 app instance id

The SMB2_CREATE_APP_INSTANCE_ID create context is used with durable v2
opens to identify another open from the same application instance. When
a new durable v2 open arrives with the same AppInstanceId as an existing
open, the server should close the previous open without sending an
oplock break notification.

ksmbd ignored this create context. A second durable v2 batch oplock open
with the same AppInstanceId therefore went through the normal competing
open path and sent an oplock break to the first opener. smbtorture
smb2.durable-v2-open.app-instance expects no oplock break and then
expects the old handle to be closed.

Parse and store AppInstanceId for durable v2 opens. Before creating the
new open, find an existing file with the same AppInstanceId and close it
through the normal close teardown path without issuing an oplock break.

Subject: [PATCH 4469/5214] ksmbd: preserve open change time across rename

inode ctime is updated when a file is renamed. ksmbd returned that
ctime directly as SMB2 ChangeTime for handle-based query information.
This makes ChangeTime change after a rename through an already-open
handle, while Windows keeps the handle's ChangeTime stable for this
case.

Store the SMB ChangeTime in struct ksmbd_file when the handle is opened
and use that value for create, close, and handle-based query information
responses.  If a client explicitly sets FILE_BASIC_INFORMATION
ChangeTime, update the stored value as well.

This fixes smbtorture smb2.rename.simple_modtime, which expects
ChangeTime and LastWriteTime to remain unchanged after renaming an
already-open file.

Subject: [PATCH 4470/5214] ksmbd: check parent directory sharing conflicts on
 rename

When renaming a file, some existing opens on the parent directory must
block the rename with STATUS_SHARING_VIOLATION. This includes parent
directory handles opened with DELETE access and handles opened without
FILE_SHARE_DELETE.

ksmbd checked only the parent's desired access for FILE_DELETE.  That
handled smb2.rename.share_delete_and_delete_access, but missed the case
where the parent directory was opened without delete access and without
delete sharing, so smb2.rename.no_share_delete_no_delete_access incorrectly
succeeded.

Attribute-only parent opens, however, must not block the rename.
smb2.rename.msword opens the parent directory with only SYNCHRONIZE and
FILE_READ_ATTRIBUTES, no share access, and then renames an already-open
child file.  Windows allows this pattern.

Reject parent directory handles that request DELETE access, and reject
non-attribute-only parent opens that deny FILE_SHARE_DELETE, while allowing
attribute-only parent opens to coexist with child rename.

Subject: [PATCH 4471/5214] ksmbd: deny renaming directory with open children

Windows denies renaming a directory while a file below that directory is
still open. smb2.rename.rename_dir_openfile checks this by keeping a file
handle open under the directory and then attempting to rename the directory
handle.  ksmbd did not check open children before calling vfs_rename(), so
the rename incorrectly succeeded.

For non-POSIX clients, scan the global open file table for active handles
whose dentries are below the directory being renamed.  If any child is
open, fail the rename with -EACCES so the client receives
STATUS_ACCESS_DENIED.

Subject: [PATCH 4472/5214] ksmbd: propagate failed command status in related
 compounds

In a related compound request, later commands can refer to the file handle
from an earlier command using the related FID value. If the earlier
command fails without producing a valid compound FID, the later related
commands must fail with the same status instead of operating on an invalid
or stale handle.

smb2.compound.related4 sends CREATE followed by IOCTL, CLOSE and SET_INFO.
The CREATE is expected to fail with STATUS_ACCESS_DENIED, and the remaining
related commands are expected to return STATUS_ACCESS_DENIED as well. ksmbd
only stored the compound FID on successful CREATE and did not remember
failed compound statuses.

Store the failed status in the work item and make related handle-based
requests fail immediately with that status only when the compound FID is
invalid. Also preserve and consume the related FID across successful
FLUSH, READ and WRITE requests whose responses do not carry a file id. Keep
a valid compound FID across non-close failures so later related commands
can continue to use the handle.

When extracting the FID from a successful READ, WRITE or FLUSH request, use
the request structure matching the SMB2 command: READ and WRITE place
PersistentFileId and VolatileFileId at a different offset than FLUSH, so a
single smb2_flush_req cast can save the wrong value as compound_fid and
make the following related request fail with STATUS_FILE_CLOSED
(smb2.compound_async.write_write after smb2.compound_async.flush_flush).
Only update the saved compound FID when the request carries a valid
volatile FID. otherwise an all-ones related FID would overwrite the CREATE
FID and break smb2.compound.related6.

Subject: [PATCH 4473/5214] ksmbd: validate handle for create or get object id

FSCTL_CREATE_OR_GET_OBJECT_ID returned a dummy successful response without
checking whether the request handle was valid. That let an invalid related
compound handle succeed in smb2.compound.related5, although the client
expected STATUS_FILE_CLOSED.

Look up the file handle before building the object id response and fail
with STATUS_FILE_CLOSED when the handle is invalid or already closed.

Subject: [PATCH 4474/5214] ksmbd: preserve compound responses for chained
 errors

set_smb2_rsp_status() resets the response iov and compound offsets before
building an error response. That is fine for a single request, but it
corrupts a compound response when an error is detected after an earlier
compound element has already been completed.

smb2.compound.invalid4 sends a READ as the first compound element and a
bogus command as the second one. The READ response must remain in
the compound response with STATUS_END_OF_FILE, followed by the bogus
command response with STATUS_INVALID_PARAMETER. Resetting the response
state for the second command breaks the compound framing and the client
reports NT_STATUS_INVALID_NETWORK_RESPONSE.

When setting an error for a chained command, update and pin only
the current compound response slot instead of resetting the whole response.

Subject: [PATCH 4475/5214] ksmbd: return success for deferred final close

ksmbd_close_fd() marks an open file as FP_CLOSED and drops the file table
reference. If another in-flight request still holds a reference, the final
close is deferred until that request drops its reference.

The function currently returns -EINVAL in that deferred-final-close case
because fp is cleared when the reference count does not reach zero.  That
turns a valid close into STATUS_FILE_CLOSED.

smb2.compound_find.compound_find_close sends QUERY_DIRECTORY and then
closes the same directory handle before receiving the find response.
The query holds a reference while it builds the response, so close must
mark the handle closed and return success even though final teardown is
delayed. Track whether the handle was successfully transitioned to
FP_CLOSED and return success when only the final close is deferred.

Subject: [PATCH 4476/5214] ksmbd: send pending interim for last compound I/O

smb2.compound_async.write_write and smb2.compound_async.read_read expect
the last I/O request in a compound request to become cancellable before
its final response is received. smb clients mark a request cancellable
after receiving an interim STATUS_PENDING response.

ksmbd handled the last READ/WRITE synchronously and returned the final
response directly, so the client never observed STATUS_PENDING and
req->cancel.can_cancel remained false.

For the last READ or WRITE in a compound request, register the work briefly
as async and send a STATUS_PENDING interim response before continuing with
the normal synchronous completion. The final READ/WRITE response remains
unchanged.

Subject: [PATCH 4477/5214] ksmbd: honor stream delete sharing for base file

smb2.streams.delete opens an alternate data stream without
FILE_SHARE_DELETE and then tries to delete the base file.  Windows rejects
the base-file delete with STATUS_SHARING_VIOLATION while the stream handle
is open. ksmbd tracks stream opens on the same ksmbd_inode as the base
file, but the delete-on-close path only checked delete access on the base
handle before marking the inode delete-pending.  As a result, deleting
the base file succeeded even though an open stream handle denied delete
sharing. Add a helper to detect open stream handles on the same inode that
do not allow FILE_SHARE_DELETE, and reject base-file delete pending and
DELETE opens with a sharing violation in that case.

Subject: [PATCH 4478/5214] ksmbd: reject empty-attribute synchronize-only
 create

smb2.create.gentest checks each desired access bit independently and
expects an open that requests only SYNCHRONIZE with CreateDisposition
OPEN_IF and FileAttributes 0 to fail with STATUS_ACCESS_DENIED.

Rejecting all SYNCHRONIZE-only opens is too broad: SYNCHRONIZE does not
imply read, write, or delete data access, and
smb2.sharemode.sharemode-access expects a SYNCHRONIZE-only open to succeed
when it does not conflict with the existing share mode.

Limit the rejection to the gentest create shape: SYNCHRONIZE-only access,
OPEN_IF disposition, and no file attributes. Other synchronize-only opens
are handled by the normal permission and share-mode checks.

Subject: [PATCH 4479/5214] ksmbd: tighten create file attribute validation

smb2.create.gentest checks each create FileAttributes bit independently and
expects FILE_ATTRIBUTE_INTEGRITY_STREAM and FILE_ATTRIBUTE_NO_SCRUB_DATA to
be rejected with STATUS_INVALID_PARAMETER.

ksmbd validates create FileAttributes against FILE_ATTRIBUTE_MASK, which
includes those bits. It also rejects only requests that have no known
attribute bit at all, so a request containing both known and unknown bits
can pass validation.

Use a create-specific attribute mask that excludes INTEGRITY_STREAM and
NO_SCRUB_DATA, and reject any bit outside that mask.

Subject: [PATCH 4480/5214] ksmbd: return requested create allocation size

smb2.create.blob sends an SMB2_CREATE_ALLOCATION_SIZE create context with
a 1MiB allocation size and expects the create response AllocationSize field
to match the requested size.  smb2.create.open additionally compares the
AllocationSize returned in the CREATE response with the AllocationSize
returned by FILE_ALL_INFORMATION on the same handle.

ksmbd applies the allocation with fallocate(), but then fills both the
create response and handle-based information from stat.blocks << 9.  On
filesystems such as ext4 this can include filesystem allocation rounding
and metadata effects, causing a response larger than the SMB2 allocation
size context and a disagreement between the two queries.

Remember the requested allocation size while processing the create context,
store the reported allocation size in struct ksmbd_file, and use it for
both the create response and handle-based allocation size responses. Update
the stored value when FILE_ALLOCATION_INFORMATION changes it, and fall back
to stat.blocks << 9 when no allocation size context was provided.

Subject: [PATCH 4481/5214] ksmbd: apply create security descriptor first

smb2.create.aclfile creates files with an SMB2_CREATE_SD_BUFFER create
context and expects the resulting security descriptor to match
the descriptor supplied by the client.

ksmbd currently tries to inherit the parent DACL first and only parses
the SMB2_CREATE_SD_BUFFER context when DACL inheritance fails.
If inheritance succeeds, the explicit security descriptor supplied on
create is ignored. This breaks create requests that include owner/group
information in the security descriptor.

Apply the create security descriptor first when the context is present.
Fall back to the existing inherited/default ACL path only when no create
security descriptor was supplied.

Subject: [PATCH 4482/5214] ksmbd: downgrade oplock after break timeout

smb2.oplock.batch22a opens a file with a batch oplock and then issues a
second open that waits for the oplock break timeout.  After the timeout the
second open should succeed, but the granted oplock level must be level II.

When the break times out, oplock_break() returns -ENOENT after invalidating
the previous opener.  smb_grant_oplock() went straight to set_lev with the
original requested oplock level, so the second open could be granted a new
batch oplock.  Downgrade the requested oplock to level II on the -ENOENT
break-timeout path before granting the oplock to the new open.

A break that completes because the previous owner closed its handle from
the oplock break handler must be distinguished from a real timeout.
smb2.oplock.batch7 closes the first handle during the break wait, and the
second open is then expected to be granted the originally requested batch
oplock.  Return -EAGAIN from the non-lease break path when the previous
opener closed during the break wait, recheck sharing in smb_grant_oplock(),
and grant the requested oplock if the close removed the conflict. Real
break timeouts still return -ENOENT and keep the downgrade to level II.

Subject: [PATCH 4483/5214] ksmbd: avoid level II oplock break notification on
 unlink

smb2_util_unlink() opens the target with FILE_DELETE_ON_CLOSE and then
closes that handle.  Other clients can also mark a file for delete with
SMB2 SET_INFO FileDispositionInformation.

When these unlink paths break existing SMB2 level II oplocks, ksmbd sends
an unsolicited SMB2_OPLOCK_BREAK notification to none.  This races with the
synchronous CREATE or SET_INFO response expected by the client, and
smbtorture reports NT_STATUS_INVALID_NETWORK_RESPONSE while running
smb2.oplock.exclusive2.

SMB2 level II oplock breaks do not require an acknowledgment in the delete
path.  Keep lease handling unchanged, but drop plain SMB2 level II oplocks
locally for unlink requests without sending a break notification.  Normal
write/truncate paths still send the level II to none notification,
preserving the behavior covered by smb2.oplock.levelII500.

Subject: [PATCH 4484/5214] ksmbd: return oplock protocol error for level II
 ack

SMB2 level II to none oplock breaks do not require an acknowledgment from
the client.  smb2.oplock.levelii500 intentionally acknowledges such a break
and expects the server to reject it with STATUS_INVALID_OPLOCK_PROTOCOL.

ksmbd drops the local level II oplock to none immediately after sending the
break notification because it does not wait for an ACK.  When the client
then sends the invalid ACK, smb20_oplock_break_ack() sees that the oplock
is not in OPLOCK_ACK_WAIT state and returns STATUS_INVALID_DEVICE_STATE
before checking the current oplock level.

If the oplock is already none when an unexpected SMB2 oplock break ACK
arrives, report STATUS_INVALID_OPLOCK_PROTOCOL.  Keep the existing
STATUS_INVALID_DEVICE_STATE response for other unexpected non-wait states.

Subject: [PATCH 4485/5214] ksmbd: normalize ungrantable lease states

smb2.lease.request verifies which SMB2 lease state combinations are granted
by the server.  Requests for H-only, W-only, and HW leases are valid lease
state bitmasks, but they are not grantable combinations and should be
returned as lease state none.

ksmbd only checked that the requested bits were inside the SMB2 lease state
mask.  As a result it could grant H-only, W-only, or HW requests and return
non-zero lease states where the client expects no lease.

Keep the bitmask validation, but normalize ungrantable combinations to zero
before allocating or looking up the lease.  The grantable combinations
remain unchanged: R, RH, RW, and RHW.

Subject: [PATCH 4486/5214] ksmbd: break handle caching for share conflicts

smb2.lease.break_twice first opens a file with an RHW lease and then tries
a second open with restrictive sharing.  That open must fail with a sharing
violation, but the existing lease should be broken from RHW to RW because
only handle caching conflicts with the requested sharing.

ksmbd used the normal write-cache break calculation for this path, so RHW
was broken to RH.  The following successful open then did not generate the
expected second break from RW to R.

Pass share-conflict context into the lease break helper and, for lease
breaks caused by sharing, drop only SMB2_LEASE_HANDLE_CACHING from the
current lease state.  Other break paths keep the existing write/truncate
break behavior.

A share-conflict break must also remain a single break.  The triggering
open fails with a sharing violation and is never granted, so there is no
target oplock level to converge on.  The lease break retry loop, however,
keeps breaking while the lease level is still above req_op_level, which
broke RHW all the way down to R in one open (lease_break_info.count became
2 instead of 1).  Skip the again loop for share-conflict breaks so the
sharing open produces exactly one RHW->RW break and the later successful
open produces the separate RW->R break the test expects.

Subject: [PATCH 4487/5214] ksmbd: break conflicting-open leases only as far as
 needed

smb2.lease.oplock and smb2.lease.breaking1 hold a lease and then issue a
single conflicting open on the same file.  The held lease must break one
step to drop write caching (RWH->RH, RW->R) and then stop, so
lease_break_info.count is 1 and the lease keeps its read/handle caching.

ksmbd instead cascaded the break all the way down to none
(e.g. RWH->RH->R->none), so the break count was 2 or 3 and the reported
lease state ended at 0.  Commit "chain pending lease breaks before waking
waiters" forces break_level to SMB2_OPLOCK_LEVEL_NONE for any non-lease
open against a handle-caching lease, which drives oplock_break()'s retry
loop down to none even when only one open is contending.

Drop that break_level override so a conflicting open breaks a lease only
to its own compatible level (level II, i.e. RH/R).

A deeper break is still required when a truncating open is also waiting
behind the same lease break.  smb2.lease.breaking3 keeps a normal open
pending through RWH->RH and an overwrite open pending behind it, and
expects the lease to continue RH->R->none before either open completes.
The overwrite waiter sets open_trunc on the lease while it blocks on the
pending break, so extend the retry loop to chain another break while that
truncating waiter still needs the lease at none.  The per-break open_trunc
snapshot stays cleared, so the cascade steps down (RH->R->none) instead of
collapsing straight to none, and the normal open stays pending until the
lease is fully broken.

Subject: [PATCH 4488/5214] ksmbd: validate :: stream type against directory
 create

smb2.streams.dir opens <dir>::$DATA with FILE_DIRECTORY_FILE and expects
STATUS_NOT_A_DIRECTORY, then opens <dir>::$DATA without it and expects
STATUS_FILE_IS_A_DIRECTORY.

Commit "treat unnamed DATA stream as base file" canonicalizes the ::$DATA
suffix to a NULL stream name so the open continues through the base-file
path. That skipped the stream/directory type validation, which was
guarded by "if (stream_name)", so opening a directory's ::$DATA stream
with FILE_DIRECTORY_FILE incorrectly returned STATUS_OK and a plain open
of it no longer reported STATUS_FILE_IS_A_DIRECTORY.

parse_stream_name() still records the explicit $DATA type in s_type even
when it clears stream_name.  Run the data-stream vs directory validation
whenever s_type is DATA_STREAM, not only when stream_name is set, so the
canonicalized ::$DATA open is rejected with the correct status.

Subject: [PATCH 4489/5214] ksmbd: treat read-control opens as stat opens only
 for leases

A second open that requests only metadata-level access must not break
the existing caching state. ksmbd already skips the break for such opens
via fp->attrib_only (FILE_READ_ATTRIBUTES,
FILE_WRITE_ATTRIBUTES and FILE_SYNCHRONIZE).

An open requesting only READ_CONTROL (reading the security descriptor)
must be treated differently depending on the existing caching state.
smbtorture smb2.lease.statopen4 expects a read-control open NOT to break
a caching lease, while smb2.oplock.statopen1 expects the same open to
break a batch oplock. So READ_CONTROL is a stat open for leases but not
for oplocks.

Extend the stat-open break-skip in smb_grant_oplock() to also cover a
read-control-only open, but only when the existing holder is a lease.
The global fp->attrib_only flag (used for share-mode, rename and truncate
decisions) is left unchanged so oplock behaviour is preserved.

Subject: [PATCH 4490/5214] ksmbd: start file id allocation at 1

ksmbd allocates both the volatile id (per-session file table) and the
persistent id (global file table) with idr_alloc_cyclic() starting at 0.
The first open after the module loads therefore gets volatile id 0 and
persistent id 0, and ksmbd returns an SMB2 FileId of {0, 0} in the create
response.

Clients treat an all-zero FileId as a null handle. smbtorture's
smb2_util_handle_empty() considers {0, 0} empty, so tests that guard the
close with it (e.g. smb2.oplock.statopen1, smb2.lease.statopen*) never
close that first handle. The leaked open keeps the inode's oplock count
non-zero, so a later batch oplock request on the same file is downgraded
to level II and the test fails.

Start the id allocation at 1 (KSMBD_START_FID) so no handle is ever
assigned a {0, 0} FileId, matching the behaviour of other SMB servers.

Subject: [PATCH 4491/5214] ksmbd: sleep interruptibly in the durable handle
 scavenger

The durable handle scavenger kthread waits up to DURABLE_HANDLE_MAX_TIMEOUT
(300 seconds) between scans using wait_event_timeout(), which sleeps in
TASK_UNINTERRUPTIBLE. When there are no durable handles pending expiry the
task stays in D state far longer than 120 seconds, so the hung task
detector prints a bogus "task ksmbd-durable-s blocked for more than 120
seconds" warning with a backtrace, even though the thread is only idle.

Use wait_event_interruptible_timeout() so the thread sleeps in
TASK_INTERRUPTIBLE, which the hung task detector ignores. This also suits
the already-freezable kthread. Treat a negative return (e.g. -ERESTARTSYS)
like a timeout when recomputing the next wake interval.

Subject: [PATCH 4492/5214] ksmbd: fix UBSAN array-index-out-of-bounds in
 decode_compress_ctxt()

decode_compress_ctxt() walks CompressionAlgorithms[] using the client
supplied CompressionAlgorithmCount. That field is declared in
struct smb2_compression_capabilities_context as a fixed 4-element array,
but the number of algorithms is actually variable and clients such as
Windows advertise more than four (e.g. LZ77, LZ77+Huffman, LZNT1,
Pattern_V1 and LZ4).

The on-wire context length is already validated, so the access is within
the received buffer, but indexing the statically sized [4] array makes
UBSAN report an out-of-bounds access:

  UBSAN: array-index-out-of-bounds in smb2pdu.c:1122:48
  index 4 is out of range for type '__le16 [4]'
  Call Trace:
   smb2_handle_negotiate+0xda7/0xde0 [ksmbd]
   ksmbd_smb_negotiate_common+0x27b/0x3e0 [ksmbd]
   smb2_negotiate_request+0x14/0x20 [ksmbd]
   handle_ksmbd_work+0x181/0x500 [ksmbd]

Walk the algorithms through a pointer so the fixed-array bounds check is
not applied, while keeping the existing length validation that bounds the
loop to the data actually received.

Subject: [PATCH 4494/5214] hdlc_ppp: sync per-proto timers before freeing hdlc
 state

Each PPP control protocol (LCP/IPCP/IPV6CP) embedded in struct ppp
registers a timer via timer_setup(). That struct ppp is the
hdlc->state allocation, which detach_hdlc_protocol() frees with kfree()
in both teardown paths: unregister_hdlc_device() and the re-attach inside
attach_hdlc_protocol().

The ppp proto never registered a .detach callback, so
detach_hdlc_protocol() performs no timer synchronization before the
kfree(). The only cancel, timer_delete(&proto->timer) in ppp_cp_event(),
is partial (it does not wait for a running callback) and only runs on the
->CLOSED transition; ppp_stop()/ppp_close() do not sync either. A
ppp_timer callback already executing (blocked on ppp->lock) survives the
kfree and then dereferences proto->state / ppp->lock in freed memory,
leading to a use-after-free.

Fix this by adding a .detach helper that calls timer_shutdown_sync() on
every per-proto timer. detach_hdlc_protocol() invokes proto->detach(dev)
before kfree(hdlc->state), so timer_shutdown_sync()
now runs on both free paths.
timer_shutdown_sync() is used instead of timer_delete_sync() because the
keepalive path re-arms the timer through add_timer()/mod_timer() and
shutdown blocks any re-activation during teardown.

Initialize the per-protocol timers in ppp_ioctl() when the protocol is
attached, and remove the now-redundant timer_setup() from ppp_start(), so
that the timers are initialized exactly once at attach time and
ppp_timer_release() never operates on uninitialized timer_list
structures. attach_hdlc_protocol() uses kmalloc() (not kzalloc), so
struct ppp's protos[i].timer is uninitialized garbage until the first
timer_setup(); without this init-at-attach, attaching the PPP protocol
without ever bringing the device up would leave timer_shutdown_sync()
operating on uninitialized memory in .detach. Moving the init out of
ppp_start() (which only runs on NETDEV_UP) into the attach path makes the
initialization unconditional and avoids initializing the same timer_list
twice.

This bug was found by static analysis.

Subject: [PATCH 4495/5214] ipv6: Fix null-ptr-deref in fib6_nh_mtu_change().

fib6_nh_mtu_change() re-fetches idev via __in6_dev_get(arg->dev) and
dereferences idev->cnf.mtu6 without a NULL check. addrconf_ifdown()
clears dev->ip6_ptr with RCU_INIT_POINTER() after rt6_disable_ip() has
released tb6_lock, so the RA-driven MTU walk can observe a NULL idev and
oops. The caller rt6_mtu_change_route() guards its own __in6_dev_get(),
but this re-fetch is unguarded; nexthop-backed routes survive
addrconf_ifdown()'s flush, so the walk still reaches it after ip6_ptr is
nulled.

Return 0 when idev is NULL, matching rt6_mtu_change_route() and the
fib6_mtu() fix in commit 5ad509c1fdad ("ipv6: Fix null-ptr-deref in
fib6_mtu().").

Subject: [PATCH 4496/5214] eth: bnxt: improve the timing of stats

Kernel selftests wait 1.25x of the promised stats refresh time
(as read from ethtool -c). bnxt reports 1sec by default, but
the stats update process has two steps. First device DMAs the
new values, then the service task performs update in full-width
SW counters. So the worst case delay is actually 2x.

Note that the behavior is different for ring stats and port stats.
Port stats are fetched synchronously by the service worker, so
there's no risk of doubling up the delay there.

The problem of stale stats impacts not only tests but real workloads
which monitor egress bandwidth of a NIC. The inaccuracy causes double
counting in the next cycle and spurious overload alarms.

Try to read from the DMA buffer more aggressively, to mitigate
timing issues between DMA and service task. The SW update should
be cheap.

Subject: [PATCH 4497/5214] ipv4: fib: Don't ignore error route in local/main
 tables.

When CONFIG_IP_MULTIPLE_TABLES is enabled but no rule is added,
fib_lookup() performs route lookup directly on two tables.

Since the first lookup does not properly bail out, the result
of an error route in the merged local/main table could be
overwritten by another route in the default table:

  # unshare -n
  # ip link set lo up
  # ip route add 192.168.0.0/24 dev lo table 253
  # ip route add unreachable 192.168.0.0/24
  # ip route get 192.168.0.1
  192.168.0.1 dev lo table default uid 0
      cache <local>

Once a random rule is added, the error route is respected:

  # ip rule add table 0
  # ip rule del table 0
  # ip route get 192.168.0.1
  RTNETLINK answers: No route to host

Let's fix the inconsistent behaviour.

If the allocation of fp[i].tpa_info fails, the error path will not free

Subject: [PATCH 4499/5214] net: airoha: Fix TX scheduler queue mask loop upper
 bound
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In airoha_qdma_set_chan_tx_sched(), the loop clearing queue mask was
using AIROHA_NUM_TX_RING (32) instead of AIROHA_NUM_QOS_QUEUES (8).

Each channel has 8 queues, and TXQ_DISABLE_CHAN_QUEUE_MASK(channel, i)
computes BIT(i + (channel * 8)). With i ranging 0..31, this causes:
- channel 0: clears bit 0..31 (all 4 channels) instead of 0..7
- channel 1: clears bit 8..31 (channels 1-3) instead of 8..15
- channel 2: clears bit 16..31 (channels 2-3) instead of 16..23
- channel 3: clears bit 24..31 (channel 3 only) - correct by accident

While BIT(32+) on arm64 produces 64-bit values truncated to 0 in u32
mask parameter, the loop still incorrectly clears queues within the
same channel beyond queue 7.

Even though this is functionally harmless (the register resets to 0
and is only ever cleared, never set — so clearing extra bits is a
no-op), the loop bound is semantically wrong and should be fixed for
correctness and clarity.

Fix by using AIROHA_NUM_QOS_QUEUES (8) as the loop upper bound.

 bounds

The net-next-hw spinners on netdev.bots.linux.dev observe failing
so-txtime-py tests. A review of stdout shows most failures to be
due to exceeding the 4ms grace period. All I saw were within 8ms.
So increase to that.

Double the bounds from 4 to 8ms. This is still is small enough to
differentiate the delays programmed by the test, 10 and 20ms.

Subject: [PATCH 4501/5214] md/raid5: use stripe state snapshot in
 break_stripe_batch_list()

The patch just suppress KCSAN noise. No functional change.

RAID-5 can group multi full-stripe-write aka stripe_head into a
batch aka batch_list, with one head_sh leading them. Call
break_stripe_batch_list() when the batch is finished, or,
a stripe has to be dropped out of the batch.

break_stripe_batch_list() reads stripe state several times while
request paths can update thost state words concurrently with
lockless bitops, which reported by KCSAN.

Use a snapshot to guarantees that the value used for
warning, copying, and handle checks is internally consistent
at current read moment.

Subject: [PATCH 4502/5214] md/raid5: avoid R5_Overlap races while breaking
 stripe batches

KCSAN report a race in break_stripe_batch_list() vs. raid5_make_request()
on sh->dev[i].flags (plain word write vs. atomic bit op)..

and .. one possible scenario is:

CPU1                            CPU2
break_stripe_batch_list(sh1)
-> handle sh2
-> lock(sh2)
-> sh2->batch_head = NULL
-> unlock(sh2)
-> test_and_clear_bit(R5_Overlap, sh2->dev[i].flags)
-> wake_up_bit(sh2->dev[i].flags)
                                raid5_make_request()
                                -> add_all_stripe_bios(sh2)
                                -> lock(sh2)
                                -> stripe_bio_overlaps(sh2) returns true
				   batch_head is NULL, so new bio overlap
				   exist bio on sh2 -> true
                                -> set_bit(R5_Overlap, sh2->dev[i].flags)
                                -> unlock(sh2)
                                -> wait_on_bit(sh2->dev[i].flags)
-> sh2->dev[i].flags = sh1->dev[i].flags & ~R5_Overlap

No wait_up_bit(), CPU2 could be wait_on_bit() forever...

Fix by :
- Expand the protect zone.
- Use batch_head's device flag's snaphot when no held head_sh->stripe_lock.
- Move sh/head_sh->batch_head = NULL to the end of protected zone , and ,
  any concurrent add_all_stripe_bios() grabs sh->stripe_lock now either:
	- see batch_head != null, and , is rejected by stripe_bio_overlaps()
	  under the lock (no R5_Overlap wait ) , or ,
	- sees batch_head == NULL, only after dev[i].flags has already been
	  set and the prior R5_Overlap waiters worken.

Subject: [PATCH 4503/5214] bpf: Disable xfrm_decode_session hook attachment

BPF LSM programs can currently attach to xfrm_decode_session(). That
hook may return an error, but security_skb_classify_flow() calls it
from a void path and triggers BUG_ON() if an error is returned.

Disable BPF attachment to the hook to prevent a BPF LSM program from
turning packet classification into a full panic.

Subject: [PATCH 4504/5214] Input: goodix - clamp the device-reported contact
 count

goodix_ts_read_input_report() copies the number of touch points reported
by the device into an on-stack buffer

	u8 point_data[2 + GOODIX_MAX_CONTACT_SIZE * GOODIX_MAX_CONTACTS];

which is sized for at most GOODIX_MAX_CONTACTS (10) contacts. The only
runtime check bounds the per-interrupt count against ts->max_touch_num,
but that value is taken verbatim from a 4-bit field of the device
configuration block and is never clamped:

	ts->max_touch_num = ts->config[MAX_CONTACTS_LOC] & 0x0f;

The nibble can be 0..15, so a malfunctioning, malicious or counterfeit
controller (or an attacker tampering with the I2C bus) can advertise up
to 15 contacts. goodix_ts_read_input_report() then accepts a touch_num
of up to 15 and the second goodix_i2c_read() writes
ts->contact_size * (touch_num - 1) bytes past the one-contact header into
point_data - up to 30 bytes (45 with the 9-byte report format) beyond the
92-byte buffer: a stack out-of-bounds write.

Clamp max_touch_num to GOODIX_MAX_CONTACTS, the number of contacts
point_data[] is sized for, when reading it from the configuration.

Subject: [PATCH 4505/5214] Input: iforce - bound the device-reported
 force-feedback effect index

iforce_process_packet() handles a status report (packet id 0x02) by
taking a force-feedback effect index straight from the device wire and
using it to address the per-effect state array:

	i = data[1] & 0x7f;
	if (data[1] & 0x80) {
		if (!test_and_set_bit(FF_CORE_IS_PLAYED,
				      iforce->core_effects[i].flags))
			...
	} else if (test_and_clear_bit(FF_CORE_IS_PLAYED,
				      iforce->core_effects[i].flags)) {
		...
	}

The index is masked only with 0x7f, so it ranges 0..127, but
core_effects[] holds only IFORCE_EFFECTS_MAX (32) entries.  For an index
of 32..127 the test_and_set_bit()/test_and_clear_bit() is an
out-of-bounds single-bit read-modify-write past the array.  core_effects[]
is the second-to-last member of struct iforce, so the write lands in the
trailing members and beyond the embedding kzalloc()'d iforce_serio /
iforce_usb object.

data[1] is unvalidated device payload on both transports (the USB
interrupt endpoint and serio), and the status path is not gated on force
feedback being present, so a malicious or counterfeit device can set or
clear a bit at an attacker-chosen offset past the object.

Reject an out-of-range index instead of indexing with it.  Bound against
the array dimension IFORCE_EFFECTS_MAX rather than dev->ff->max_effects so
the check guarantees memory safety regardless of how many effects the
device registered.  A legitimate "effect started/stopped" status always
carries an index below IFORCE_EFFECTS_MAX, so well-formed devices are
unaffected; the neighbouring mark_core_as_ready() loop is already bounded
and is left untouched.

Subject: [PATCH 4506/5214] Input: stop force-feedback timer when unregistering
 input devices

Memoryless force-feedback devices use a timer to manage playback of
effects. When a driver for such a device is unbound (or the device is
unregistered for other reasons), the driver typically frees its private
data synchronously. However, the input_dev structure (and its associated
force-feedback structures, including the timer) is only freed when the
last user closes the corresponding device node.

If userspace keeps the device node open while the device is unregistered
(e.g., during driver unbind), the force-feedback timer can still fire
after the driver's private data has been freed.

Introduce a new 'stop' callback to struct ff_device, and call it from
input_unregister_device() before the device is deleted. Implement this
callback for memoryless devices and synchronously shut down the timer to
ensure it is stopped and cannot be rearmed once unregistration happens.

Subject: [PATCH 4507/5214] Input: elan_i2c - prevent division by zero and
 arithmetic underflow

The Elan I2C touchpad driver queries the device for its physical
dimensions and trace counts to calculate the device resolution and width.
However, if the device firmware or device tree provides invalid zero
values for x_traces or y_traces, it results in a fatal division-by-zero
exception leading to a kernel panic during device probe.

Add checks to ensure these parameters are non-zero before performing
the division. If invalid trace values are detected, fall back to a safe
default of 1.

Additionally, prevent an arithmetic underflow in the touch reporting
logic. Previously, if the calculated or fallback width was smaller than
ETP_FWIDTH_REDUCE (90), the subtraction would underflow, resulting in a
massive unsigned integer being reported to userspace. Clamp the adjusted
width to a minimum of 0 to safely handle small physical dimensions and
fallback scenarios.

Completing the probe with safe fallback values ensures the sysfs nodes
are created, keeping the firmware update path intact so a recovery
firmware can be flashed to the device.

Subject: [PATCH 4508/5214] Input: mms114 - fix touch indexing for MMS134S and
 MMS136

The MMS134S and MMS136 touch controllers have an event size of 6 bytes
rather than 8 bytes. When __mms114_read_reg() reads the touch data
packet from the device into the touch buffer, the events are packed
tightly at 6-byte intervals. However, the driver iterates through the
events using standard C array indexing (touch[index]), where each
element is sizeof(struct mms114_touch) (8 bytes) apart. As a result, any
touch events beyond the first one are read from incorrect offsets and
parsed improperly.

Fix this by explicitly calculating the byte offset for each touch event
based on the device's specific event size.

==================================================================

The out-of-bounds report, though, is a red herring as it is for an
access that shouldn't have happened in the first place.

When nf_nat_init() fails to register its BPF kfuncs, it'll unwind and,
among others, call unregister_pernet_subsys() to deregister its per-net
ops. This makes the previously allocated net id available for reuse by
the next caller of register_pernet_subsys(), in our case, synproxy.
However, 'nat_net_id' will still hold the previously allocated value.

If nf_nat.o gets build as a module, all this doesn't matter. A failed
initialization routine makes the module fail to load and any dependent
module won't be able to load either. However, if nf_nat.o is built-in,
a failing init won't /completely/ make its functionality unavailable to
dependent modules, namely the code and static data is still there, free
to be called by modules like nft_chain_nat.ko.

Case in point, nft_chain_nat registers hooks that'll call into nf_nat
which, in our case, failed to initialize and therefore won't have a
valid net id nor related net_nat object any more.

Code in nf_nat, namely nf_nat_register_fn() and nf_nat_unregister_fn(),
still making use of the reallocated net id, lead to a type confusion as
the call to net_generic() will no longer return memory belonging to an
object suited to fit 'struct nat_net' but 'struct synproxy_net' instead.
The latter is only 24 bytes on 64-bit systems, much smaller than struct
nat_net which is 176 bytes, perfectly explaining the OOB KASAN report.

Detect and handle a failed nf_nat_init() by testing the 'nf_nat_hook'
pointer which will be reset to NULL on initialization errors to prevent
the usage of an invalid nat_net pointer.

As this check is only needed when nf_nat.o is built-in, guard it by
'#ifndef MODULE...'.

Subject: [PATCH 4510/5214] netfilter: nf_conncount: prevent connlimit drops
 for early confirmed ct

Commit 69894e5b4c5e ("netfilter: nft_connlimit: update the count if add
was skipped") introduced a regression where packets for valid
connections are dropped when using connlimit for soft-limiting
scenarios.

The issue occurs when a new connection reuses a socket currently in
the TIME_WAIT state. In this scenario, the connection tracking entry
is evaluated as already confirmed. Previously, __nf_conncount_add()
assumed that if a connection was confirmed and did not originate from
the loopback interface, it should skip the addition and return -EEXIST.

Skipping the addition triggers a garbage collection run that cleans up
the TIME_WAIT connection. Consequently, the active connection count
drops to 0, which xt_connlimit mishandles, leading to the false rejection
of the perfectly valid new connection.

Fix this by replacing the interface check with protocol-agnostic state
checks. We now skip the tree insertion and preserve the lockless garbage
collection optimization only if the connection is IPS_ASSURED. This
allows early-confirmed setup packets (such as reused TIME_WAIT sockets
or locally generated SYN-ACKs) to be properly evaluated and counted
without falsely dropping. The goto check_connections path is maintained
to ensure these setup packets are deduplicated correctly.

This has been tested with slowhttptest and HTTP server configured
locally to ensure we are not breaking soft-limiting scenarios for local
or external connections. In addition, it was tested with a OVS zone
limit too.

Subject: [PATCH 4513/5214] netfilter: nft_synproxy: stop bypassing the
 priv->info snapshot

nft_synproxy_eval_v4() and nft_synproxy_eval_v6() already take a
whole-object READ_ONCE() snapshot of the shared priv->info state before
building the SYNACK reply, but nft_synproxy_tcp_options() still masks
opts->options with priv->info.options from the live shared object.

When a named synproxy object is updated concurrently with SYN traffic,
the eval path can then mix mss and timestamp handling from the local
snapshot with an options mask taken from a newer configuration, so one
SYNACK no longer reflects a coherent synproxy configuration.

Use info->options so nft_synproxy_tcp_options() stays on the same local
snapshot that the eval path already copied from priv->info.

Subject: [PATCH 4514/5214] selftests: netfilter: conntrack_sctp_collision.sh:
 Introduce SCTP INIT collision test

The existing test covered a scenario where a delayed INIT_ACK chunk
updates the vtag in conntrack after the association has already been
established.

A similar issue can occur with a delayed SCTP INIT chunk.

Add a new simultaneous-open test case where the client's INIT is
delayed, allowing conntrack to establish the association based on
the server-initiated handshake.

When the stale INIT arrives later, it may get recorded and cause a
following INIT_ACK from the peer to be accepted instead of dropped.
This INIT_ACK overwrites the vtag in conntrack, causing subsequent
SCTP DATA chunks to be considered as invalid and then dropped by
nft rules matching on ct state invalid.

This test verifies such stale INIT chunks do not cause problems.

Subject: [PATCH 4515/5214] netfilter: nft_compat: ebtables emulation must
 reject non-bridge targets

xtables targets return netfilter verdicts: NF_ACCEPT, NF_DROP, and so
on.  ebtables targets return incompatible verdicts: EBT_ACCEPT,
EBT_DROP, ...   We cannot allow fallback to NFPROTO_UNSPEC.

ebtables doesn't permit this since
11ff7288beb2 ("netfilter: ebtables: reject non-bridge targets")
but that commit missed the nft_compat layer.

Add a test queueing from bridge family.
This was lacking: we queued from inet for ipv4 and ipv6 but
we had no bridge queue test so far.

Given kernel MUST validate that in/out port are still part of
a bridge device on reinject add a test case for this before
adding this check.

Subject: [PATCH 4517/5214] netfilter: ctnetlink: do not allow to reset helper
 on existing conntrack

This feature allows to reset a helper for an existing conntrack, but it
is not safe. This requires a synchronized_rcu() call after resetting the
helper, which is going to be expensive for a large batch of conntrack
entries. This also needs to call to the .destroy callback to release the
GRE/PPTP mappings to fix it.

This feature antedates the creation of the conntrack-tools and I cannot
find a good use-case for this. Given that I cannot find any user in the
netfilter.org userspace tree, I prefer to remove this feature.

Subject: [PATCH 4518/5214] apparmor: mediate the implicit connect of TCP fast
 open sendmsg

sendmsg()/sendto() with MSG_FASTOPEN is a combination of connect(2) and
write(2): it opens the connection in the SYN. apparmor_socket_sendmsg()
only checks AA_MAY_SEND, so a profile that grants send but denies connect
lets a confined task open an outbound TCP/MPTCP connection that connect(2)
would have refused, bypassing connect mediation.

Mediate the implicit connect when MSG_FASTOPEN is set and a destination
is supplied. Add it to apparmor_socket_sendmsg() (not the shared
aa_sock_msg_perm() helper, which recvmsg also uses) and call aa_sk_perm()
directly, mirroring the selinux and tomoyo fixes. sk_is_tcp() does not
cover MPTCP fast open, so the SOCK_STREAM/IPPROTO_MPTCP arm is explicit.

Subject: [PATCH 4519/5214] fbdev: vga16fb: Drop unused assignment of
 platform_device_id driver data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver explicitly sets the .driver_data member of struct
platform_device_id to zero without relying on that value. Drop these
unused assignments.

While touching this array unify spacing and usage of commas and use
named initializers for .name.

Subject: [PATCH 4521/5214] gpio: tegra: do not call pinctrl for GPIO direction

tegra_gpio_direction_input() and tegra_gpio_direction_output() already
program the GPIO controller direction registers directly. The additional
pinctrl_gpio_direction_input/output() calls do not add a Tegra pinctrl
operation, because the Tegra pinmux ops provide GPIO request/free
handling but no gpio_set_direction hook.

The extra call still enters the pinctrl core and takes pctldev->mutex.
Shared GPIO users can call the direction path while holding their
per-line spinlock, so this otherwise redundant pinctrl direction call can
sleep in an atomic context.

This was found by our static analysis tool and then confirmed by manual
review of tegra_gpio_probe(), the Tegra GPIO direction callbacks and the
Tegra pinctrl ops. The reviewed path has a default non-sleeping
struct gpio_chip while the direction callback still enters the pinctrl
mutex path.

A directed runtime validation kept the same non-sleeping chip registration
and drove:

  gpio_shared_proxy_direction_output()
  gpiod_direction_output_raw_commit()
  tegra_gpio_direction_output()
  pinctrl_gpio_direction_output()

Lockdep reported a sleep-in-atomic warning with the shared GPIO spinlock
held and pinctrl_get_device_gpio_range() plus tegra_gpio_direction_output()
on the stack.

Do not mark the whole chip as can_sleep to paper over this: can_sleep
describes whether get()/set() may sleep, and Tegra value access is MMIO.
Remove the redundant pinctrl direction calls and keep pinctrl involvement
in the existing request/free path.

Subject: [PATCH 4522/5214] gpio: davinci: fix IRQ domain leak on devm_kzalloc
 failure

In davinci_gpio_irq_setup(), after successfully creating an IRQ domain
with irq_domain_create_legacy(), a subsequent devm_kzalloc() failure
in the bank loop causes the function to return -ENOMEM without
removing the IRQ domain.

Unlike devm-managed resources, irq_domain_create_legacy() does not
auto-clean up on probe failure, so the domain is leaked.

Fix by calling irq_domain_remove() before returning on allocation
failure.

Subject: [PATCH 4524/5214] netfilter: conntrack: add deprecation warnings for
 irc and pptp trackers

IRC Direct client-to-client requires plaintext.  IRC over TLS should be
preferred, making this helper ineffective.  Add a deprecation warning and
update the help text to better reflect that this is needed for the DCC
extension, not IRC itself.

PPTP is esoteric these days and it is the only helper that requires the
destroy callback in the conntrack helper API.

Removal would simplify the conntrack core.

Both helpers are IPv4 only.

Subject: [PATCH 4527/5214] netfilter: nft_ct: expectation timeouts are passed
 in milliseconds

Userspace passes '5000' in case user asks for 5 seconds.

Allowing for sub-second expectation lifetimes makes sense to me. so
fix up the kernel side instead of munging nft to send a value rounded
up to next second.

Also note that this violates nft convention of passing integers in
network byte order, but we can't change this anymore.

Subject: [PATCH 4528/5214] netfilter: nf_conntrack_helper: cap maximum number
 of expectation at helper registration

On helper registration, the maximum number of expectations cannot go over
NF_CT_EXPECT_MAX_CNT (255), but zero can be specified then
nf_conntrack_expect_max applies. Turn zero into NF_CT_EXPECT_MAX_CNT
otherwise, expectation LRU eviction on insertion is disabled.

Moreover, expand this sanity check all expectation classes.

This max_expecy policy is only tunable since userspace helpers are
available, set Fixes: tag to the commit that adds such infrastructure.

Remove the check for p->max_expected given this field must always
be non-zero after this patch.

Subject: [PATCH 4529/5214] soundwire: Move wait for initialisation helper to
 header

As SoundWire devices tend to enumerate on the bus after probe, drivers
frequently need to wait for the device to initialise from common driver
code. The common system is to split drivers into a core module and then
a module for each communication bus. These two facts tend to cause
Kconfig issues, the issue tends to be when SOUNDWIRE=m and DRIVER_I2C=y,
this usually selects DRIVER=y. The driver code then wants to call
sdw_slave_wait_for_init(), but this results in calling a module function
from built in code. A depends on SOUNDWIRE | !SOUNDWIRE could be added to
the end driver but this seems slightly off as it adds a lot of counter
intuitive depends.

A simpler solution is to make sdw_slave_wait_for_init() a static inline
function. As part of doing this add a check for the slave device being
NULL acknowledging that this is likely called from code that is shared
between control buses. It does require dropping the call to
sdw_show_ping_status() but this can be added back in end drivers that
used it originally.

Currently this is causing rand config issues on RT5682 and will soon
also cause similar problems on cs42l43.

Subject: [PATCH 4534/5214] cpuidle: Allow exit latency to exceed target
 residency

Commit 76934e495cdc ("cpuidle: Add sanity check for exit latency and
target residency") had added a check to prevent the exit latency of an
idle state from exceeding its target residency that later was limited to
printing a warning message in that case in commit 4bf944f3fcb6 ("cpuidle:
Warn instead of bailing out if target residency check fails").

However, a thorough code inspection with that in mind leads to the
conclusion that actually there are no assumptions in cpuidle regarding
the relationship between the exit latency and target residency of a
given idle state.  It is generally assumed that the idle states table
provided by a cpuidle driver will be sorted by both the target residency
and exit latency in ascending order, but that's a different matter.

Accordingly, drop the check in question along with the message printed
when it triggers and the inaccurate comment preceding it.

Subject: [PATCH 4535/5214] ASoC: SDCA: Validate written enum value in
 ge_put_enum_double()

ge_put_enum_double() passes the user-supplied enumeration index
item[0] to snd_soc_enum_item_to_val() without checking it against the
number of items in the enum:

	ret = snd_soc_enum_item_to_val(e, item[0]);

snd_soc_enum_item_to_val() indexes the heap-allocated e->values[] array
with that index (e->values is set from a devm_kcalloc() of e->items
entries), so a control write with an out-of-range item[0] reads past the
end of the values buffer.  The bounds check in
snd_soc_dapm_put_enum_double() only runs afterwards, so it does not
prevent the read here.

Reject an out-of-range item before using it, matching the other enum put
handlers.

This issue was pointed out by the Sashiko AI review bot while reviewing a
related enum-validation series:

Subject: [PATCH 4536/5214] ASoC: tas2783: Update loaded firmware names to
 linux-firmware 20260519

In linux-firmware commit from 2026-05-19 `2f90f4fe5c67f51a8410907a...`
`ASoC: tas2783: Add Firmware files for tas2783A projects` by Baojun Xu
138 new firmware files for tas2783 were added, none of which are loaded
by the kernel. Kernel expects files to be named with the following
convention: "%04X-%1X-%1X.bin". However the added firmware files follow
"-0x%1X.bin" naming instead with `0x` hex prefix, which fails to load
resulting in following dmesg log:

  slave-tas2783 sdw:0:1:0102:0000:01:8: Direct firmware load for 1714-1-8.bin failed with error -2
  slave-tas2783 sdw:0:1:0102:0000:01:8: Failed to read fw binary 1714-1-8.bin
  slave-tas2783 sdw:0:1:0102:0000:01:b: Direct firmware load for 1714-1-B.bin failed with error -2
  slave-tas2783 sdw:0:1:0102:0000:01:b: Failed to read fw binary 1714-1-B.bin
  slave-tas2783 sdw:0:1:0102:0000:01:8: error playback without fw download
  slave-tas2783 sdw:0:1:0102:0000:01:8: ASoC error (-22): at snd_soc_dai_hw_params() on tas2783-codec

This same commit removes all 22 symlinks from WHENCE, that used naming
without the '0x' prefix to only 6 prevoiusly existing .bin files.

This patch adds `0x` prefix explicitly to the generated firmware name
allowing file to successfully load. In case prefixed firmware is missing
due to out of date linux-firmware, we set the fallback flag and attempt
to load firmware again based on the old file names.

This prefix change results in functioning firmware loading on ASUS
ProArt PX13 HN7306EAC, which uses 1714-1-0x8.bin and 1714-1-0xB.bin
firmware files.

Tested on top of 7.1 and next-20260619 with SND_SOC_AMD_ACP7X set to no.

Subject: [PATCH 4538/5214] i2c: mpc: Fix timeout calculations

At first glance the harmless cleanup of the driver does nothing bad.
However, as the operator precedence list states the '*' (multiplication)
and '/' division operators have order 5 with left-to-right associativity
the *= has order 17 and associativity right-to-left. It wouldn't be
a problem to replace

	foo = foo * HZ / 1000000;

with

	foo *= HZ / 1000000;

if HZ constant is in Hertz. The problem is that in the Linux kernel HZ is
defined in jiffy units, which is order of magnitude smaller than a million.
That's why operator precedence has a crucial role here. Fix the regression
by reverting pre-optimized calculations.

Subject: [PATCH 4539/5214] PCI: endpoint: pci-epf-vntb: Exclude reserved slots
 from db_valid_mask

In pci-epf-vntb, db_count represents the total number of doorbell slots
exposed to the peer, including:

  - slot #0 reserved for link events, and

  - slot #1 historically unused (kept for compatibility).

Only the remaining slots correspond to actual doorbell bits. The current
db_valid_mask() exposes all slots as valid doorbells.

Limit db_valid_mask() to the real doorbell bits by returning
BIT_ULL(db_count - 2) - 1, and guard against db_count < 2.

Subject: [PATCH 4540/5214] i2c: i801: fix hardware state machine corruption in
 error path

A severe livelock and subsequent Hung Task panic were observed in the
i2c-i801 driver during concurrent Fuzzing. The crash is caused by an
unconditional hardware register cleanup in the error handling path of
i801_access().

When i801_check_pre() fails (e.g., returning -EBUSY because the SMBus
controller is actively used by BIOS/ACPI), the kernel does not actually
acquire the hardware ownership. However, the code jumps to the 'out'
label and executes:

    iowrite8(SMBHSTSTS_INUSE_STS | STATUS_FLAGS, SMBHSTSTS(priv));

This forcefully clears the INUSE_STS lock and resets the hardware status
flags without owning the controller. Doing so interrupts ongoing BIOS/ACPI
transactions and totally corrupts the SMBus hardware state machine.

Consequently, all subsequent i801_access() calls fail at the pre-check
stage, triggering an endless stream of "SMBus is busy, can't use it!"
error logs. Over a slow serial console, this printk flood monopolizes
the CPU (Console Livelock), starving other processes trying to acquire
the mmap_lock down_read semaphore, ultimately triggering the hung task
watchdog.

Fix this by moving the 'out' label below the hardware register cleanup.
If i801_check_pre() fails, we safely bypass the iowrite8() and only
release the software locks (pm_runtime and mutex), strictly adhering to
the rule of not releasing resources that were never acquired.

Subject: [PATCH 4541/5214] PCI: endpoint: pci-epf-vntb: Implement
 .db_vector_count()/mask() for doorbells

Implement .db_vector_count() and .db_vector_mask() so NTB core/clients can
map doorbell events to per-vector work and avoid the thundering-herd
behavior.

pci-epf-vntb reserves two slots in db_count: slot 0 for link events and
slot 1 which is historically unused. Therefore the number of doorbell
vectors is (db_count - 2).

Report vectors as 0..N-1 and return BIT_ULL(db_vector) for the
corresponding doorbell bit. Build db_valid_mask from a validated vector
count so out-of-range db_count values cannot create invalid shifts.

Subject: [PATCH 4542/5214] NTB: epf: Document legacy doorbell slot offset in
 ntb_epf_peer_db_set()

ntb_epf_peer_db_set() uses ffs(db_bits) to select a doorbell to ring.
ffs() returns a 1-based bit index (bit 0 -> 1).

Entry 0 is reserved for link events, so doorbell bit 0 must map to entry
1. However, since the initial commit 812ce2f8d14e ("NTB: Add support for
EPF PCI Non-Transparent Bridge"), the implementation has been adding an
extra +1, ending up using entry 2 for bit 0. Fixing the extra increment
would break interoperability with peers running older kernels.

Keep the legacy behavior and document the offset and the resulting slot
layout to avoid confusion when enabling per-db-vector handling.

ntb_db_event() expects the vector number to be relative to the first
doorbell vector starting at 0.

Vector 0 is reserved for link events in the EPF driver, so doorbells
start at vector 1. However, both supported peers (ntb_hw_epf with
pci-epf-ntb, and pci-epf-vntb) have historically skipped vector 1 and
started doorbells at vector 2.

Pass (irq_no - 2) to ntb_db_event() so doorbells are reported as 0..N-1.
If irq_no == 1 is ever observed, warn and ignore it, since the slot is
reserved in the legacy layout and reporting it as DB#0 would collide with
the real DB#0 slot.

Subject: [PATCH 4545/5214] NTB: epf: Fix doorbell bitmask and IRQ vector
 handling

The EPF driver currently stores the incoming doorbell as a vector number
(irq_no + 1) in db_val and db_clear() clears all bits unconditionally.
This breaks db_read()/db_clear() semantics when multiple doorbells are
used.

Store doorbells as a bitmask (BIT_ULL(vector)) and make
db_clear(db_bits) clear only the specified bits. Use atomic64 operations
as db_val is updated from interrupt context.

Once db_val is stored as a bitmask, the ISR's doorbell vector is used
not only for ntb_db_event(), but also as the bit index for BIT_ULL().
The existing ISR derives that vector by subtracting pci_irq_vector(pdev,
0) from the Linux IRQ number passed to the handler, but Linux IRQ
numbers are not guaranteed to be contiguous.

Pass per-vector context as request_irq() dev_id instead, so the ISR gets
the device vector directly.

Validate the doorbell vector before updating db_val or calling
ntb_db_event(), so an unexpected vector cannot create an invalid shift
or be reported to NTB clients.

While at it, read and validate mw_count before requesting interrupt
vectors. An unsupported memory-window count does not need IRQs, and
failing before ntb_epf_init_isr() keeps the probe error path simple.

Subject: [PATCH 4546/5214] NTB: epf: Implement .db_vector_count()/mask() for
 doorbells

Implement .db_vector_count() and .db_vector_mask() so NTB core/clients can
map doorbell events to per-vector work.

Report vectors as 0..(db_count - 2) (skipping the unused slot) and return
BIT_ULL(db_vector) for the corresponding doorbell bit. Use
ntb_epf_db_vector_count() for bounds checks in ntb_epf_db_vector_mask(), so
the same lower-bound guard is applied before building the bitmask.

Subject: [PATCH 4547/5214] PCI: Rename 'added' to 'add_list'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The resource fitting algorithm uses different names from the list holding
the optional sizes: added, add_head, add_list, and realloc_head. 'add_list'
sounds the most natural and some of the related variables also use 'add'
such as 'add_size'.

To reduce variation, rename 'added' and 'add_head' to 'add_list'.  Also
rename some 'realloc_head' cases selectively to 'add_list'.

While it would be nice to rename every 'realloc_head' to 'add_list' for
consistency, it might create a backport headache with all the work going
into this algorithm that may need to be eventually backported. Thus, it's
better to leave 'realloc_head' as is for now.

Subject: [PATCH 4548/5214] PCI: Consolidate add_list (aka realloc_head) empty
 sanity checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Callers of __pci_bridge_assign_resources() and __pci_bus_assign_resources()
perform WARN_ON_ONCE(list_empty(add_list))) checks to sanity check that all
optional sizes were processed (and removed) from the list. The empty list
sanity check is duplicated code so the more appropriate place for it would
be inside the called function.

Placing the empty list check into __pci_bus_assign_resources() also ensures
all callsites do perform the sanity check which currently is not the case
when being called from enable_slot(). This inconsistency was noted by
Sashiko though only inside its in depth log but not flagged as a real
problem, possibly because this is only a sanity check that should never
fire. Nonetheless, this sanity check has been very useful to catch problems
early in the past so it's good to do it consistently everywhere.

As __pci_bus_assign_resources() is a recursive function, it needs to be
renamed to __pci_bus_assign_resources_one() to only perform the empty list
check at the end of processing the entire hierarchy in
__pci_bus_assign_resources().

Subject: [PATCH 4549/5214] PCI: Remove const removal cast
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

__pci_bridge_assign_resources() inputs const pci_dev *bridge, but then
immediately casts const away to pass the bridge to
pdev_assign_resources_sorted().

As pdev_assign_resources_sorted() performs assignment of resources, it
is not possible to make its input parameter to const. Neither of the
__pci_bridge_assign_resources() callers requires the bridge parameter
to be const.

Thus, simply remove the out of place cast and convert the input parameter
to non-const.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

pci_sriov_resource_alignment() inputs struct pci_dev which it should not
need to alter to calculate alignment.

Make pci_dev pci_sriov_resource_alignment() inputs const. It requires
making pci_iov_resource_size() input const as well.

Subject: [PATCH 4556/5214] dt-bindings: PCI: renesas,r9a08g045-pcie: Add
 RZ/V2N support

Document the Renesas RZ/V2N PCIe host controller, which is compatible with
the RZ/G3E PCIe IP and therefore uses it as a fallback compatible. The
only difference is that it uses device ID 0x003B.

Make the binding title generic to avoid extending the title for each new
SoC, and update the description to list the supported SoCs and their
capabilities.

Subject: [PATCH 4558/5214] PCI: cadence-hpa: Add post-link delay

The Cadence HPA (High Performance Architecture IP) specific link setup
function cdns_pcie_hpa_host_link_setup() waits for the link to come up
but does not implement the required 100 ms delay after link training
completes for speeds > 5.0 GT/s (PCIe r6.0 sec 6.6.1).

Add a call to pci_host_common_link_train_delay() immediately after the
link is confirmed to be up, using the max_link_speed field. Also, in the
HPA host setup function, read the device tree property "max-link-speed"
to initialize max_link_speed if not already set by a glue driver.

This ensures compliance for HPA-based platforms.

Subject: [PATCH 4563/5214] PCI/proc: Fix race between pci_proc_init() and
 pci_bus_add_device()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pci_proc_attach_device() creates procfs entries for PCI devices and is
called from pci_bus_add_device().  It lazily creates the per-bus procfs
directory (bus->procdir) via proc_mkdir() on first use, and returns early
if proc_initialized is not yet set.

On x86 with ACPI, PCI enumeration occurs at subsys_initcall, before
pci_proc_init() sets proc_initialized at device_initcall.  The
for_each_pci_dev() loop in pci_proc_init() then creates procfs entries for
these already-enumerated devices, but runs without holding
pci_rescan_remove_lock.

On ARM64 with devicetree, PCI host bridges probe at device_initcall.  With
async probing enabled, pci_bus_add_device() can run concurrently with
pci_proc_init(), and both may call pci_proc_attach_device() for the same
device or for different devices on the same bus.  As pci_host_probe() holds
pci_rescan_remove_lock while pci_proc_init() does not, there is no
serialisation between the two paths.

When two threads concurrently call pci_proc_attach_device() for devices on
the same bus, both observe bus->procdir as NULL and both call proc_mkdir().
The proc filesystem serialises directory creation internally, so only one
caller succeeds.  The other results in a warning like:

  proc_dir_entry '000c:00/00.0' already registered

The caller receives NULL (duplicate entry) and unconditionally stores it to
bus->procdir, corrupting the valid pointer set by the first caller.

Serialise access to proc_initialized, proc_bus_pci_dir, bus->procdir and
dev->procent with a new mutex local to drivers/pci/proc.c, and store the
created entries to bus->procdir and dev->procent only on success, so a
failed creation can never overwrite a valid pointer.

Additionally, wrap the for_each_pci_dev() loop in pci_proc_init() with
pci_lock_rescan_remove() to serialise against concurrent PCI bus
operations, add an early return in pci_proc_attach_device() when
dev->procent is already set to make the function idempotent, and clear
bus->procdir in pci_proc_detach_bus() to prevent use of a dangling pointer
after proc_remove().

Subject: [PATCH 4564/5214] PCI/sysfs: Convert PCI resource files to static
 attributes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, the PCI resource files (resourceN, resourceN_wc) are dynamically
created by pci_create_sysfs_dev_files(), called from both
pci_bus_add_device() and the pci_sysfs_init() late_initcall, with only a
sysfs_initialized flag for synchronisation.  This has caused warnings and
boot panics when both paths race on the same device, e.g.:

  sysfs: cannot create duplicate filename '/devices/pci0000:3c/0000:3c:01.0/0000:3e:00.2/resource2'

This is especially likely on Devicetree-based platforms, where the PCI host
controllers are platform drivers that probe via the driver model, which can
happen during or after the late_initcall.  As such, pci_bus_add_device()
and pci_sysfs_init() are more likely to overlap.

Convert to static const attributes with three attribute groups (I/O, UC,
WC), each with an .is_bin_visible() callback that checks resource flags,
BAR length, and non_mappable_bars.  A .bin_size() callback provides
pci_resource_len() to the kernfs node for correct stat and lseek behaviour.

As part of this conversion:

  - Rename pci_read_resource_io() and pci_write_resource_io() to
    pci_read_resource() and pci_write_resource() since the callbacks are no
    longer I/O-specific in the static attribute context.

  - Update __resource_resize_store() to use sysfs_create_groups() and
    sysfs_remove_groups(), which re-evaluates visibility and runs the
    .bin_size() callback for the static resource attribute groups.

  - Remove pci_create_resource_files(), pci_remove_resource_files(), and
    pci_create_attr() which are no longer needed.

  - Move the __weak stubs outside the #if guard so they remain available
    for callers converted in subsequent commits.

Platforms that do not define the HAVE_PCI_MMAP macro or the
ARCH_GENERIC_PCI_MMAP_RESOURCE macro, such as Alpha architecture,
continue using their platform-specific resource file creation.

For reference, the dynamic creation dates back to the pre-Git era:

  https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/drivers/pci/pci-sysfs.c?id=42298be0eeb5ae98453b3374c36161b05a46c5dc

The write-combine support was added in commit 45aec1ae72fc ("x86: PAT
export resource_wc in pci sysfs").

Many other reports mentioned in the cover letter (first Link: below).

Subject: [PATCH 4565/5214] PCI/sysfs: Warn about BAR resize failure in
 __resource_resize_store()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a pci_warn() to __resource_resize_store(), so that BAR resize failures
are visible to the user, which can help troubleshoot any potential resource
resize issues.

While at it, rename the resource_resize_is_visible() to
resource_resize_attr_is_visible() along with the corresponding group
variable to align with the naming convention used by the resource attribute
groups.

Also, change the order of pci_dev_groups[] such that the resize group is
now located alongside the other resource groups.

Subject: [PATCH 4566/5214] PCI/sysfs: Add stubs for
 pci_{create,remove}_sysfs_dev_files()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On platforms with HAVE_PCI_MMAP or ARCH_GENERIC_PCI_MMAP_RESOURCE, resource
files are now handled by static attribute groups registered via
pci_dev_groups[].

Stub out the pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files(),
as the dynamic resource file creation is no longer needed.

Also, simplify pci_sysfs_init() on these platforms to only iterate buses
for legacy attributes creation, skipping the per-device loop.

Move the __weak stubs for pci_create_resource_files() and
pci_remove_resource_files() into the #else branch since only platforms
without HAVE_PCI_MMAP (such as Alpha architecture) still need them.  Guard
the res_attr[] and res_attr_wc[] fields in struct pci_dev the same way.

Subject: [PATCH 4567/5214] PCI/sysfs: Limit pci_sysfs_init() late_initcall
 compile scope
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, pci_sysfs_init() and sysfs_initialized compile unconditionally,
even on platforms where static attribute groups handle all resource file
creation.

Place them behind a new HAVE_PCI_SYSFS_INIT macro, especially as the
late_initcall is only needed when:

  - HAVE_PCI_LEGACY is set, to iterate buses and create legacy I/O and
    memory files.

  - Neither HAVE_PCI_MMAP nor ARCH_GENERIC_PCI_MMAP_RESOURCE is set, to
    iterate devices and create resource files via the __weak
    pci_create_resource_files() stub override (this is how the Alpha
    architecture handles this currently).

On most systems both conditions are false and the entire late_initcall
compiles away.

Subject: [PATCH 4568/5214] alpha/PCI: Add security_locked_down() check to
 pci_mmap_resource()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, Alpha's pci_mmap_resource() does not check
security_locked_down(LOCKDOWN_PCI_ACCESS) before allowing userspace to mmap
PCI BARs.

The generic version has had this check since commit eb627e17727e ("PCI:
Lock down BAR access when the kernel is locked down") to prevent DMA
attacks when the kernel is locked down.

Add the same check to Alpha's pci_mmap_resource().

Subject: [PATCH 4569/5214] alpha/PCI: Use BAR index in sysfs attr->private
 instead of resource pointer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, Alpha's pci_create_one_attr() stores a resource pointer in
attr->private, and pci_mmap_resource() loops through all BARs to find
the matching index.

Store the BAR index directly in attr->private and retrieve the resource via
pci_resource_n().  This eliminates the loop and aligns with the convention
used by the generic PCI sysfs code.

The PCI core change was first added in the commit dca40b186b75 ("PCI: Use
BAR index in sysfs attr->private instead of resource pointer").

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the WARN() that fires when userspace attempts to mmap beyond the BAR
bounds.  The check still returns 0 to reject the mapping, but the warning
is excessive for normal operation.

A similar warning was removed from the PCI core in the commit 3b519e4ea618
("PCI: fix size checks for mmap() on /proc/bus/pci files").

Subject: [PATCH 4573/5214] alpha/PCI: Add static PCI resource attribute macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add macros for declaring static binary attributes for Alpha's PCI resource
files:

  - pci_dev_resource_attr(),        for dense/BWX systems (mmap dense)
  - pci_dev_resource_sparse_attr(), for sparse systems (mmap sparse)
  - pci_dev_resource_dense_attr(),  for dense companion files (mmap dense)

Each macro creates a const bin_attribute with the BAR index stored in the
.private property and the appropriate .mmap() callback.

Subject: [PATCH 4574/5214] alpha/PCI: Convert resource files to static
 attributes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, Alpha's PCI resource files (resourceN, resourceN_sparse,
resourceN_dense) were dynamically created by pci_create_resource_files(),
which overrides the generic __weak implementation.  The previous code
allocated bin_attributes at runtime and managed them via the res_attr[] and
res_attr_wc[] fields in struct pci_dev.

Convert to static const attributes with three attribute groups (plain,
sparse, dense), each with an .is_bin_visible() callback that checks
resource length, has_sparse(), and sparse_mem_mmap_fits().  A .bin_size()
callback provides the resource size to the kernfs node, with the sparse
variant shifting by 5 bits for byte-level addressing.

Register the groups via ARCH_PCI_DEV_GROUPS so the driver model handles
creation and removal automatically.

Use the new pci_resource_is_mem() helper for the type check, replacing the
open-coded bitwise flag test.

Finally, remove pci_create_resource_files(), pci_remove_resource_files(),
pci_create_attr(), and pci_create_one_attr() which are no longer needed.

Subject: [PATCH 4575/5214] PCI/sysfs: Remove
 pci_{create,remove}_sysfs_dev_files()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files()
are no-op stubs.  With both the generic and Alpha resource files now
handled by static attribute groups, no platform needs dynamic per-device
sysfs file creation.

Remove both functions, their declarations, and the call sites in
pci_bus_add_device() and pci_stop_dev().

Remove __weak pci_create_resource_files() and pci_remove_resource_files()
stubs and their declarations in pci.h, as no architecture overrides them
anymore.

Remove the res_attr[] and res_attr_wc[] fields from struct pci_dev which
were used to track dynamically allocated resource attributes.

Finally, simplify pci_sysfs_init() to only handle legacy file creation
under HAVE_PCI_LEGACY, removing the per-device loop and the
HAVE_PCI_SYSFS_INIT helper added earlier.

Content-Transfer-Encoding: 8bit

Add defines for the standard PCI legacy address space sizes, replacing the
raw literals used by the legacy sysfs attributes.

Then, replace open-coded values with the newly added macros.

No functional changes intended.

Subject: [PATCH 4577/5214] alpha/PCI: Compute legacy size in
 pci_mmap_legacy_page_range()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, pci_mmap_legacy_page_range() reads the legacy resource size from
bus->legacy_mem->size or bus->legacy_io->size.  This couples the mmap
bounds check to the struct pci_bus fields that will be removed when legacy
attributes are converted to static definitions.

Compute the size directly using PCI_LEGACY_MEM_SIZE (0x100000) and
PCI_LEGACY_IO_SIZE (0xffff) macros, and shift by 5 bits for sparse systems.

Subject: [PATCH 4578/5214] PCI/sysfs: Add __weak pci_legacy_has_sparse()
 helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, Alpha's sparse/dense legacy attribute handling is done via
pci_adjust_legacy_attr(), which updates dynamically allocated attributes at
runtime.  The upcoming conversion to static attributes needs a way to
determine sparse support at visibility check time.

Add a __weak pci_legacy_has_sparse() that returns false by default.  Alpha
overrides it to check has_sparse() on the bus host controller.

Subject: [PATCH 4579/5214] PCI/sysfs: Convert legacy I/O and memory attributes
 to static definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, legacy_io and legacy_mem are dynamically allocated and created
by pci_create_legacy_files(), with pci_adjust_legacy_attr() updating the
attributes at runtime on Alpha to rename them and shift the size for sparse
addressing.

Convert to four static const attributes (legacy_io, legacy_io_sparse,
legacy_mem, legacy_mem_sparse) with .is_bin_visible() callbacks that use
pci_legacy_has_sparse() to select the appropriate variant per bus.  The
sizes are compile-time constants and .size is set directly on each
attribute.

Register the groups in pcibus_groups[] under a HAVE_PCI_LEGACY guard so the
driver model handles creation and removal automatically.

Stub out pci_create_legacy_files() and pci_remove_legacy_files() as the
dynamic creation is no longer needed.  Remove the __weak
pci_adjust_legacy_attr(), Alpha's override, and its declaration from both
Alpha and PowerPC asm/pci.h headers.

Subject: [PATCH 4580/5214] PCI/sysfs: Remove pci_create_legacy_files() and
 pci_sysfs_init()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, pci_create_legacy_files() and pci_remove_legacy_files() are
no-op stubs.  With legacy attributes now handled by static groups
registered via pcibus_groups[], no call site needs them.

Remove both functions, their declarations, and the call sites in
pci_register_host_bridge(), pci_alloc_child_bus(), and pci_remove_bus().

Remove the pci_sysfs_init() late_initcall and sysfs_initialized.  The
late_initcall originally existed to create all the dynamic PCI sysfs files,
but with both resource and legacy attributes now handled by static groups,
it is no longer needed.

Remove the legacy_io and legacy_mem fields from struct pci_bus which were
used to track the dynamically allocated legacy attributes.

Subject: [PATCH 4581/5214] PCI/sysfs: Limit BAR resize attribute scope to
 platforms with PCI mmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, __resource_resize_store() uses sysfs_remove_groups() and
sysfs_create_groups() on pci_dev_resource_attr_groups to tear down and
recreate the resourceN files after a BAR resize, so the updated BAR sizes
are visible in sysfs.

The resourceN files only exist on platforms that define HAVE_PCI_MMAP or
ARCH_GENERIC_PCI_MMAP_RESOURCE.  On platforms that define neither,
pci_dev_resource_attr_groups is NULL and the sysfs_remove_groups() and
sysfs_create_groups() calls in __resource_resize_store() become no-ops.

Resizable BAR (ReBAR) is a PCI Express Extended Capability
(PCI_EXT_CAP_ID_REBAR) that requires PCIe extended config space.  Every
PCIe-capable architecture defines HAVE_PCI_MMAP or
ARCH_GENERIC_PCI_MMAP_RESOURCE (via arch headers or the asm-generic/pci.h
fallback).  Architectures without either only support conventional PCI and
cannot have any ReBAR-capable devices.

Move the resize show and store helpers, the per-BAR attribute definitions,
and the attribute group behind the existing #ifdef HAVE_PCI_MMAP ||
ARCH_GENERIC_PCI_MMAP_RESOURCE guard, and fold the group reference in
pci_dev_groups[] into the existing #if block.

Subject: [PATCH 4582/5214] PCI/sysfs: Use kstrtobool() to parse the ROM
 attribute input
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pci_write_rom() controls access to the ROM content through the
corresponding sysfs attribute, and treats the input as a request to
disable only when it matches the string "0\n" exactly:

  if ((off ==  0) && (*buf == '0') && (count == 2))

The count == 2 condition encodes the trailing newline that echo(1) appends.
This was found when userspace wrote "0" without a trailing newline aiming
to disable access, which failed to match the condition above and enabled
access instead.  For example:

  $ echo 0 > rom       # "0\n", count 2, access disabled
  $ echo -n 0 > rom    # "0", count 1, access enabled
  $ echo > rom         # "", count 1, access enabled (likely not desirable)

Parse the input with kstrtobool(), which handles common boolean inputs such
as "0", "1", "n", "y" or "off", "on", with or without a trailing newline,
so both of the above disable access, and update the now stale comment.

As a side effect, input that does not parse as a boolean is rejected with
-EINVAL rather than enabling access.  The documented "0" and "1" continue
to work as before, and rejecting malformed input brings the attribute in
line with how sysfs attributes typically handle it.

Subject: [PATCH 4585/5214] Docs/driver-api/uio-howto: document mmap_prepare
 callback

The UIO howto still documents an mmap callback in struct uio_info.
That field was replaced by mmap_prepare, which takes a struct
vm_area_desc.

A UIO driver following the current howto no longer builds because
struct uio_info has no mmap member. Update the documented callback
signature and matching text to match the current API.

Fixes: 933f05f58ac6 ("uio: replace deprecated mmap hook with mmap_prepare in uio_info")

Subject: [PATCH 4590/5214] selftests/xsk: make poll timeout mode explicit

Stop inferring timeout behavior from RX UMEM initialization state.
That ties timeout semantics to setup internals and obscures intent.

Use test_spec::poll_tmout as the explicit timeout-mode selector in
TX and RX paths.

In RX, treat poll timeout as expected only in timeout mode.
In TX, let send_pkts() own loop completion in non-timeout mode
and use __send_pkts() only for progress and timeout detection.

This makes timeout logic explicit and keeps control flow predictable.

Subject: [PATCH 4591/5214] selftests/xsk: fix timeout thread harness
 sequencing

Prevent workers from running before XDP program attachment completes.
The previous ordering allowed races between worker startup and setup.

Attach XDP programs before entering traffic validation.

Remove SIGUSR1-based worker termination and use pthread_join() for
thread shutdown so blocking syscalls are not interrupted.

Use barriers only for dual-thread runs so participants match and
teardown ordering stays deterministic.

This removes setup/startup races and stabilizes harness sequencing.

Subject: [PATCH 4592/5214] selftests/xsk: restore shared_umem after
 POLL_TXQ_FULL

POLL_TXQ_FULL temporarily disables shared_umem on TX to exercise the
TX timeout path in isolation.

With shared_umem enabled, TX setup expects RX UMEM to be initialized
first and fails with: "RX UMEM is not initialized before shared-UMEM TX
setup".

Save and restore shared_umem around POLL_TXQ_FULL execution, and restore
it on both success and pkt_stream_replace() failure paths.

Also add an in-code comment explaining why shared_umem is temporarily
disabled in this test.

This keeps timeout setup local and prevents cross-test state leakage.

drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_color.c contains 7 (for
now) functions that use STATIC_IFN_KUNIT or INLINE_IFN_KUNIT macros for
function qualifiers (static or not, inline or not).

These cause parse warnings from kernel-doc:

STATIC_IFN_KUNIT const struct drm_color_lut * __extract_blob_lut (const

Subject: [PATCH 4594/5214] net, bpf: check master for NULL in
 xdp_master_redirect()

xdp_master_redirect() dereferences the result of
netdev_master_upper_dev_get_rcu() without a NULL check, but that helper
returns NULL when the receiving device has no upper-master adjacency.

The reach guard only checks netif_is_bond_slave(). On bond slave release
bond_upper_dev_unlink() drops the upper-master adjacency before clearing
IFF_SLAVE, so an XDP_TX reaching xdp_master_redirect() in that window
still passes netif_is_bond_slave() while master is already NULL, and
faults on master->flags at offset 0xb0:

  BUG: kernel NULL pointer dereference, address: 00000000000000b0

The missing check dates back to the original code; commit 1921f91298d1
("net, bpf: fix null-ptr-deref in xdp_master_redirect() for down master")
later added the master->flags read where the fault now lands but kept the
unconditional deref. Check master for NULL before use; a NULL master is
treated the same as one that is not up.

Subject: [PATCH 4596/5214] net: do not acquire dev->tx_global_lock in
 netdev_watchdog_up()

Marek Szyprowski reported a deadlock during system resume when virtio_net
driver is used.

The deadlock occurs because netif_device_attach() is called while holding
dev->tx_global_lock (via netif_tx_lock_bh() in virtnet_restore_up()).
netif_device_attach() calls __netdev_watchdog_up(), which now also tries
to acquire dev->tx_global_lock to synchronize with dev_watchdog().

This recursive lock acquisition results in a deadlock.

Fix this by removing the tx_global_lock acquisition from netdev_watchdog_up().

The critical state (watchdog_timer and watchdog_ref_held) is already
protected by dev->watchdog_lock, which was introduced in the blamed commit.

pin_duration is converted from the user-provided period to SJA1105
clock ticks and is later passed as the cycle_time argument to
future_base_time().

Very small period values may become zero after the conversion,
which can lead to a division by zero in future_base_time().

Round zero pin_duration up to 1 tick so that the smallest unsupported
periods use the minimum non-zero hardware duration instead of passing
zero to future_base_time().

emac_xsk_xmit_zc() handles tx xmit for zero copy and gets called
inside napi context. User application wakes up the kernel while
initiating the transmit which triggers napi to start processing
the tx packets. The num_tx check inside emac_tx_complete_packets()
returns early if no packet transfer happen hindering the call
to emac_xsk_xmit_zc(). Remove this check to let application
wakeup initiate zero copy xmit traffic.

Add __netif_tx_lock() to ensure that the TX queue is protected
from concurrent access during the transmission of XDP frames.
This fixes netdev watchdog timeout for long runs.

Subject: [PATCH 4599/5214] veth: fix NAPI leak in XDP enable error path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

During XDP enablement in veth, if xdp_rxq_info_reg() or
xdp_rxq_info_reg_mem_model() fails, the driver rolls back the changes.

However, the rollback loop:
	for (i--; i >= start; i--) {

decrements the loop index 'i' before the first iteration. This
correctly skips unregistering the rxq for the failed index 'i' (as
registration failed or was already cleaned up), but it also
erroneously skips calling netif_napi_deli() for rq[i].xdp_napi.

Since netif_napi_add() was already called for index 'i', this leaves
a dangling napi_struct in the device's napi_list. When the veth
device is later destroyed, the freed queue memory (which contains the
leaked NAPI structure) can be reused.

The subsequent device teardown iterates the NAPI list and
corrupts the reallocated memory, leading to UAF.

Fix this by explicitly deleting the NAPI association for the failed
index 'i' before rolling back the successfully configured queues.

Subject: [PATCH 4600/5214] net: usb: lan78xx: restore VLAN and hash filters
 after link up

Configured VLANs intermittently stop receiving traffic after a link
down/up cycle, e.g. when the network cable is unplugged and plugged back
in. VLAN filtering stays enabled but all VLAN-tagged frames are dropped
until a VLAN is added or removed again.

The LAN7801 datasheet (DS00002123E) states:

  "A portion of the MAC operates on clocks generated by the Ethernet
   PHY. During a PHY reset event, this portion of the MAC is designed to
   not be taken out of reset until the PHY clocks are operational"
  (section 8.10, MAC Reset Watchdog Timer)

  "After a reset event, the RFE will automatically initialize the
   contents of the VHF to 0h."
  (section 7.1.4, VHF Organization)

Thus a link down/up cycle stops and restarts the PHY clock, resets the
PHY-clocked portion of the MAC, and the RFE clears its VLAN/DA hash
filter (VHF) memory. The VHF holds both the VLAN filter table and the
multicast hash table, but the driver never reprograms either from its
shadow copy once the link is back, so both stay empty.

Reprogram the VLAN filter and multicast hash tables on link up.

Subject: [PATCH 4601/5214] ksmbd: validate NTLMv2 response before updating
 session key

ksmbd_auth_ntlmv2() derives the NTLMv2 session key into
sess->sess_key before it verifies the NTLMv2 response.
ksmbd_decode_ntlmssp_auth_blob() then continues into KEY_XCH even
when ksmbd_auth_ntlmv2() failed.

With SMB3 multichannel binding, the failed authentication operates on
an existing session and the session setup error path does not expire
binding sessions. A client can send a binding session setup with a
bad NT proof and KEY_XCH and still modify sess->sess_key before
STATUS_LOGON_FAILURE is returned.

Relevant path:

  smb2_sess_setup()
    -> conn->binding = true
    -> ntlm_authenticate()
       -> session_user()
       -> ksmbd_decode_ntlmssp_auth_blob()
          -> ksmbd_auth_ntlmv2()
             -> calc_ntlmv2_hash()
             -> hmac_md5_usingrawkey(..., sess->sess_key)
             -> crypto_memneq() returns mismatch
          -> KEY_XCH arc4_crypt(..., sess->sess_key, ...)
    -> out_err without expiring the binding session

Derive the base session key into a local buffer and copy it to
sess->sess_key only after the proof matches. Return immediately on
authentication failure so KEY_XCH is only processed after successful
authentication.

Subject: [PATCH 4604/5214] net: lwtunnel: Drop skb metadata before LWT
 encapsulation

skb metadata is meant for passing information between XDP and TC. It lives
in the skb headroom, immediately before skb->data. LWT programs cannot
access the __sk_buff->data_meta pseudo-pointer to metadata.

However, LWT encapsulation prepends outer headers, moving skb->data back
over the headroom where the metadata sits. On an RX-originated (forwarded)
packet that still carries XDP metadata this goes wrong in two different
ways, depending on the encap type:

1. Non-BPF LWT encaps (mpls, seg6, ioam6 ...) call skb_push()/skb_pull()
   and silently overwrite the metadata that sits in the headroom.

2) BPF LWT xmit calls bpf_skb_change_head(), which uses skb_data_move().
   That helper expects metadata immediately before skb->data. But since
   the IP output path runs LWT xmit before neighbour output has built
   the outgoing L2 header, for forwarded packets skb->data points at the
   L3 header while skb_mac_header() still points at the old L2 header.
   skb_data_move() sees metadata ending at skb_mac_header(), not before
   skb->data, warns and clears metadata:

  WARNING: CPU: 21 PID: 454557 at include/linux/skbuff.h:4609 skb_data_move+0x47/0x90
  CPU: 21 UID: 0 PID: 454557 Comm: napi/iconduit-g Tainted: G           O        6.18.21 #1

   do_softirq+0x3f/0x60
   </IRQ>

That is what happens, as for how to fix it - a received packet that
carries metadata can reach an encap through any of the three LWT
redirect modes:

  LWTUNNEL_STATE_INPUT_REDIRECT
   ip6_rcv_finish
     dst_input
       lwtunnel_input

  LWTUNNEL_STATE_OUTPUT_REDIRECT
   ip6_rcv_finish
     dst_input
       ip6_forward
         ip6_forward_finish
           dst_output
             lwtunnel_output

  LWTUNNEL_STATE_XMIT_REDIRECT
   ip6_rcv_finish
     dst_input
       ip6_forward
         ip6_forward_finish
           dst_output
             ip6_output
               ip6_finish_output
                 ip6_finish_output2
                   lwtunnel_xmit

Every encap funnels through the three LWT dispatch helpers, so drop the
metadata there, right before handing the skb to the encap op. This
single chokepoint covers all encap types and all three redirect modes:

  - lwtunnel_input():  seg6, rpl, ila, seg6_local
  - lwtunnel_output(): ioam6
  - lwtunnel_xmit():   mpls, LWT BPF xmit

Alternatively, we could clear the metadata right after TC ingress hook.
That would require a compromise, however. Metadata would become
inaccessible from TC egress (in setups where it actually reaches the
hook it tact, that is without any L2 tunnels on path).

Subject: [PATCH 4606/5214] net/sched: cls_api: Handle TC_ACT_CONSUMED in
 tcf_qevent_handle

tcf_classify() can return TC_ACT_CONSUMED while the skb is held by the
defragmentation engine (e.g. act_ct on out-of-order fragments). When
that happens the skb is no longer owned by the caller and must not be
touched again.

tcf_qevent_handle() did not handle TC_ACT_CONSUMED: it fell through the
switch and returned the skb to the caller as if classification had
passed. The only qdisc that wires up qevents today is RED, via three call sites
(qe_mark on RED_PROB_MARK/HARD_MARK, qe_early_drop on congestion_drop)
red_enqueue() was continuing to operate on an skb it no longer owns  in this
case -- enqueueing it, dropping it, or updating statistics. Resulting in a UAF.

  tc qdisc add dev eth0 root handle 1: red ... qevent early_drop block 10
  tc filter add block 10 ... action ct

  (with ct defrag enabled and traffic that produces out-of-order
  fragments, e.g. a fragmented UDP stream)

Handle TC_ACT_CONSUMED in tcf_qevent_handle() the same way the ingress
and egress fast paths do: treat it as stolen and return NULL without
touching the skb. Unlike the TC_ACT_STOLEN case, the skb must not be
dropped/freed here, as it is no longer owned by us.

Subject: [PATCH 4607/5214] sctp: fix err_chunk memory leaks in INIT handling

When sctp_verify_init() encounters unrecognized parameters, it allocates an
err_chunk to report them. However, this chunk is leaked in several code
paths:

1. In sctp_sf_do_5_1B_init(), if security_sctp_assoc_request() fails after
   sctp_verify_init() has populated err_chunk, the function returns
   immediately without freeing it.

2. In sctp_sf_do_unexpected_init(), the same leak occurs on the
   security_sctp_assoc_request() failure path.

3. In sctp_sf_do_unexpected_init(), on the success path after copying
   unrecognized parameters to the INIT-ACK, the function returns without
   freeing err_chunk, unlike sctp_sf_do_5_1B_init() which properly frees
   it.

Fix all three leaks by adding sctp_chunk_free(err_chunk) calls before
returning in the error paths and on the success path in
sctp_sf_do_unexpected_init().

Fixes: c081d53f97a1 ("security: pass asoc to sctp_assoc_request and sctp_sk_clone")

Subject: [PATCH 4608/5214] net: au1000: move free_irq out of the close-time
 spinlocked section

au1000_close() calls free_irq() while aup->lock is still held with
spin_lock_irqsave(). free_irq() can sleep because it takes the IRQ
descriptor request mutex, so it does not belong inside the close-time
spinlocked section.

This was found by our static analysis tool and then confirmed by manual
review of the in-tree au1000_close() .ndo_stop path. The reviewed path
keeps aup->lock held across the MAC reset, queue stop and
free_irq(dev->irq, dev).

A directed runtime validation kept that ndo_stop carrier and the same
free_irq(dev->irq, dev) operation under the driver lock. Lockdep reported
"BUG: sleeping function called from invalid context" and "Invalid wait
context" while free_irq() was taking desc->request_mutex, with
au1000_close() and free_irq() on the stack.

Drop aup->lock before freeing the IRQ. The protected close-time work still
stops the device and queue before IRQ teardown, but the sleepable IRQ core
path now runs outside the spinlocked section.

Subject: [PATCH 4610/5214] ipv6: fix error handling in disable_ipv6 sysctl

When writing to the disable_ipv6 sysctl, if proc_dointvec() fails to
parse the input, it returns a negative error code. The current
implementation is overwriting that error for write operations.

This results in a silent failure, it returns a successful write although
the configuration was not modified at all. When modifying the "all"
variant it can also modify the configuration of existing interfaces to
the wrong value.

Fix this by checking the return value of proc_dointvec() and returning
early on failure.

Subject: [PATCH 4616/5214] eth: fbnic: fix ordering of heartbeat vs ownership

When requesting ownership of the NIC (MAC/PHY control), we set up
the heartbeat to look stale:

  /* Initialize heartbeat, set last response to 1 second in the past
   * so that we will trigger a timeout if the firmware doesn't respond
   */
  fbd->last_heartbeat_response = req_time - HZ;
  fbd->last_heartbeat_request = req_time;

The response handler then sets:

  fbd->last_heartbeat_response = jiffies;

for which we wait via:

  fbnic_fw_init_heartbeat() -> fbnic_fw_heartbeat_current()

The scheme is a bit odd, but it should work in principle.

Fix the ordering of operations. We have to set up the stale heartbeat
before we send the message. Otherwise if the response is very fast
we will override it. This triggers on QEMU if we run on the core
that handles the IRQ, and results in ndo_open failing with ETIMEDOUT.

The change in ordering doesn't impact releasing the ownership.
Both ndo_stop and heartbeat check are under rtnl_lock.

Subject: [PATCH 4618/5214] KVM: s390: Fix S390_USER_OPEREXEC enablement
 without STFLE 74

The KVM_CAP_S390_USER_OPEREXEC capability allows operation exceptions
to be forwarded to userspace. But the actual enablement at the hardware
level occurs in kvm_arch_vcpu_postcreate(), and only if STFLE.74 or
user_instr0 are enabled. The latter is associated with a separate
capability (KVM_CAP_S390_USER_INSTR0), so the only way this happens
for the USER_OPEREXEC capability is if STFLE.74 is enabled. KVM
unconditionally enables this bit in kvm_arch_init_vm(), but the guest
could disable it from the CPU model and thus ignore this capability.

Add USER_OPEREXEC to the check in kvm_arch_vcpu_postcreate(), such that
either capability would enable this type of exception.

Subject: [PATCH 4619/5214] KVM: s390: selftests: Extended user_operexec tests

There is a possibility that the user_operexec capability
only works if facility bit 74 is enabled. This is now fixed,
but add a selftest to demonstrate that.

Subject: [PATCH 4621/5214] s390/mm: Fix handling of _PAGE_UNUSED pte bit

The _PAGE_UNUSED softbit should not really be lying around. Its sole
purpose is to signal to try_to_unmap_one() and try_to_migrate_one()
that the page can be discarded instead of being moved / swapped.

KVM has no way to know why a page is being unmapped, so it sets the bit
on userspace ptes corresponding to unused guest pages every time they
get unmapped. KVM has no reasonable way to clear the bit once the page
is in use again.

While set_ptes() checks and clears the bit, other paths that set new
ptes did not. This led to used pages being thrown out as if they were
unused, causing guest corruption.

Fix the issue by clearing the _PAGE_UNUSED bit for present ptes in
set_pte(), i.e. whenever a present pte is getting set. The check in
set_ptes() is then redundant and can be removed.

Also fix gmap_helper_try_set_pte_unused() to only set the bit if the
pte is present; the _PAGE_UNUSED bit is only defined for present ptes
and thus should not be set for non-present ptes.

Subject: [PATCH 4622/5214] KVM: s390: Fix dat_peek_cmma() overflow

If userspace passes a start address that is out of bounds,
_dat_walk_gfn_range() will fail with -EFAULT, but state.end will not be
touched and will stay 0. This will cause *count to underflow and report
a very high number, and the function will end up erroneously reporting
success.

Fix by only setting *count if the end address is not smaller than the
starting address. This way invalid starting addresses will correctly
return -EFAULT and *count will correctly indicate that no values have
been returned.

Under heavy memory pressure, handle_sske() and handle_pfmf() might
cause an endless loop if the mmu cache runs empty, the atomic

unlikely, that scenario is not impossible.

Fix the issue by not ignoring the return value of

in case of failure.

Subject: [PATCH 4627/5214] KVM: s390: Fix cmma dirty tracking

It is possible that some guest memory areas have not been touched yet
when starting migration mode, and thus have no ptes allocated. Only
existing and allocated ptes should count toward the total of dirty cmma
entries.

When starting migration mode, enable the migration_mode flag
immediately, so that any subsequent ESSA will trap in the host and
cause cmma_dirty_pages to be increased as needed.
Subsequently, set the cmma_d bit on all existing cmma-clean PGSTEs,
increasing cmma_dirty_pages as needed. Skipping cmma-dirty pages
prevents double counting.

Conversely, when disabling migration mode, set cmma_dirty_pages to 0
and clear the cmma_d bit in all existing PGSTEs.

The invariant is that when migration mode is off, no PGSTE has its
cmma_d bit set, and cmma_dirty_pages is 0. kvm->slots_lock protects
kvm_s390_vm_start_migration() and kvm_s390_vm_stop_migration() from
each other and from kvm_s390_get_cmma_bits().

Also fix dat_get_cmma() to properly wrap around if the first attempt
reached the end of guest memory without finding cmma-dirty pages.

[ imbrenda: Moved kvm_s390_sync_request_broadcast() before gmap_set_cmma_all_dirty() ]

Subject: [PATCH 4628/5214] KVM: s390: selftests: Fix cmma selftest

The existing cmma selftest depended on the host allocating page tables
for all present memslots. Since the gmap rewrite, memory that is not
accessed by the guest might not have page tables allocated yet.

This caused the test to fail due to a mismatch in the assertion.

Fix by having the guest access also the second half of the test
memslot, thus guaranteeing that its page tables are present.

Subject: [PATCH 4630/5214] ALSA: seq: Fix uninitialised heap leak in
 snd_seq_event_dup()

snd_seq_event_dup() copies an incoming event into a pool cell and, in
the UMP-enabled build, clears the trailing cell->ump.raw.extra word that
the memcpy() did not cover.  The guard deciding whether to clear it
compares the copied size against sizeof(cell->event):

	memcpy(&cell->ump, event, size);
	if (size < sizeof(cell->event))
		cell->ump.raw.extra = 0;

For a legacy (non-UMP) event, size == sizeof(struct snd_seq_event) ==
sizeof(cell->event), so the condition is false and the extra word keeps
stale data.  The cell pool is allocated with kvmalloc() (not zeroed) and
cells are reused via a free list, so that word holds uninitialised heap
or leftover event data.

When such a cell is delivered to a UMP client (client->midi_version > 0)
that set SNDRV_SEQ_FILTER_NO_CONVERT -- so the legacy event reaches it
unconverted -- snd_seq_read() reads it out as the larger struct
snd_seq_ump_event and copies the stale word to user space, a 4-byte
kernel heap infoleak to an unprivileged /dev/snd/seq client.

Compare against sizeof(cell->ump) instead, so the trailing word is zeroed
for every event shorter than the UMP cell.

Subject: [PATCH 4631/5214] KVM: Replace guest-triggerable BUG_ON() in
 ioeventfd datamatch with get_unaligned()

Drop a BUG_ON() that has been reachable since it was first added, way back
in 2009, and instead use get_unaligned() to perform potentially-unaligned
accesses.

For a given store, KVM x86's emulator tracks the entire value in the
destination operand, x86_emulate_ctxt.dst.  If the destination is memory,
and the target splits multiple pages and/or is emulated MMIO, then KVM
handles each fragment independently.  E.g. on a page split starting at page
offset 0xffc, KVM writes 4 bytes to the first page, then the remaining
bytes to the second page, using ctxt->dst as the source for both (with
appropriate offsets).

If the destination splits a page *and* hits emulated MMIO on the second
page, then KVM will complete the write to the first page, then emulate the
MMIO access to the second page.  If there is a datamatch-enabled ioeventfd
at offset 0 of the second page, then KVM will process the remainder of the
store as a potential ioeventfd signal.

Putting it all together, if the guest emits a store that splits a page
starting at page offset N, and the second page has a datamatch-enabled
ioeventfd at offset 0, then KVM will check for datamatch using
&dst.valptr[N] as the source.  Due to dst (and thus dst.valptr) being
32-byte aligned, if N is not aligned to @len, the BUG_ON() fires.

E.g. with a 16-byte store at page offset 0xffc, to an ioeventfd of len 8,
all initial checks in ioeventfd_in_range() will succeed, and the BUG_ON()
fires due to @val being 4-byte aligned, but not 8-byte aligned.

In a perfect world, the fix would be to simply delete the BUG_ON(), as KVM
x86 doesn't perform alignment checks on "normal" memory accesses at CPL0.
Sadly, C99 ruins all the fun; while the x86 architecture plays nice,
dereferencing an unaligned pointer directly is undefined behavior in C,
e.g. triggers splats when running with CONFIG_UBSAN_ALIGNMENT=y.

Subject: [PATCH 4632/5214] KVM: x86: Replace BUG_ON() with WARN_ON_ONCE() on
 "bad" nested GPA translation

If KVM attempts to translate what it thinks is an L2 GPA with a non-nested
MMU, simply WARN and return the GPA, i.e. trust the MMU more than the
caller, as there is zero reason to potentially panic the host kernel just
because KVM misused an API.

 KVM write-protects upper SPTEs

Instead of bugging the host kernel, WARN and terminate the VM if KVM
attempts to write-protect at a level that cannot use leaf SPTEs.
There is no reason to bring down the entire host; even termininating
the VM is likely overkill, but in theory a missed write could corrupt
guest memory, so play it safe.

Subject: [PATCH 4638/5214] KVM: x86: Unconditionally recompute CR8 intercept
 on PPR update
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The TPR_THRESHOLD field in the VMCS is used by VMX to induce VM exits
when the guest's virtual TPR falls under the specified threshold,
allowing KVM to inject previously masked interrupts.

KVM handles these VM exits in handle_tpr_below_threshold().
Commit eb90f3417a0c ("KVM: vmx: speed up TPR below threshold vmexits")
optimized this function by calling apic_update_ppr() instead of raising
KVM_REQ_EVENT. apic_update_ppr() then raises KVM_REQ_EVENT if there is
a pending, deliverable interrupt.

However, if there are no new interrupts pending, apic_update_ppr() does
not issue the request. Thus, kvm_lapic_update_cr8_intercept() and
vmx_update_cr8_intercept() are not called before VM entry, which results
in a high, stale TPR_THRESHOLD. This is problematic due to the following
sentence in 28.2.1.1 "VM-Execution Control Fields" in the SDM:

  The following check is performed if the “use TPR shadow” VM-execution
  control is 1 and the “virtualize APIC accesses” and “virtual-interrupt
  delivery” VM-execution controls are both 0: the value of bits 3:0 of
  the TPR threshold VM-execution control field should not be greater
  than the value of bits 7:4 of VTPR.

This error condition is typically not observed when KVM runs on a bare
metal system because modern processors support APICv, which enables
virtual-interrupt delivery, and which KVM uses when possible. This
causes the processor to no longer generate TPR-below-threshold exits
and to no longer check TPR_THRESHOLD on entry. However, when running
on older platforms, or under nested virtualization on a hypervisor that
does not support virtual-interrupt delivery and enforces this check
(like Hyper-V) this can cause a VM entry failure with hardware error
0x7, as seen in [1].

Call kvm_lapic_update_cr8_intercept() if apic_update_ppr() does not
find a deliverable interrupt (and thus does not raise KVM_REQ_EVENT).
Remove calls to kvm_lapic_update_cr8_intercept() on paths that end up in
apic_update_ppr(), as they now become redundant. This ensures that any
path that updates the guest's PPR also figures out if KVM needs to wait
for a TPR change (using TPR_THRESHOLD on VMX or CR8 intercepts on SVM).

Subject: [PATCH 4639/5214] drm/i915/cdclk: Fix up CDCLK_FREQ_DECIMAL without a
 full PLL re-enable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The GOP (and even Bspec on some platforms) is a bit inconsistent
on what the CDCLK_FREQ_DECIMAL divider should be. Currently any
mismatch there causes a full CDCLK PLL disable+re-enable, which
we really don't want to do if any displays are currently active.
Let's instead just reprogram CDCLK_FREQ_DECIMAL when that is the
only thing amiss. For any other (more serious) mismatch we still
punt to the full PLL reprogramming.

We also need to tweak the bxt_cdclk_cd2x_pipe() stuff a bit to
consistently select pipe==NONE since we have no idea which pipes
are enabled at this point. Since we're not actually changing the
CDCLK frequency here we don't need to sync the update to any
pipe.

Subject: [PATCH 4640/5214] KVM: x86/mmu: Expose number of shadow MMU shadow
 pages as a stat

Turn arch.n_used_mmu_pages into a stat, mmu_shadow_pages, as the number of
live shadow pages is arguably _the_ most critical datapoint when it comes
to analyzing the shadow MMU.  Before the TDP MMU came along, i.e. when the
shadow MMU was the only MMU, explicitly tracking the number of shadow pages
wasn't as interesting, because the same information could more or less be
gleaned from the pages_{1g,2m,4k} stats.  But with the TDP MMU, where the
shadow MMU is only used for nested TDP, it becomes extremely difficult, if
not impossible, to determine which SPTEs are coming from the TDP MMU, and
which are coming from the shadow MMU.

E.g. when triaging/debugging shadow MMU performance issues due to "too many
shadow pages", being able to observe that 99%+ of all shadow pages are
unsync is critical to being able to deduce that KVM is effectively leaking
shadow pages.

Subject: [PATCH 4641/5214] x86/apic: KVM: Use cpu_physical_id() to get APIC ID
 of running vCPU for AVIC

Use cpu_physical_id() instead of default_cpu_present_to_apicid() when
getting the APIC ID of the pCPU on which a vCPU is running/loaded, as the
kernel has gone way off the rails if a vCPU is loaded on a pCPU that has
been physically removed from the system.  Even if the impossible were to
happen, the absolutely worst case scenario is that hardware will ring the
AIVC doorbell on the wrong pCPU, i.e. a severely broken system will
experience mild performance issues.

Kill off KVM's superfluous kvm_cpu_get_apicid() wrapper along with the
for-KVM export of default_cpu_present_to_apicid(), as they existed purely
for the wonky AVIC usage.

da9121_i2c_probe() stores i2c_get_match_data() in chip->subvariant_id
and da9121_assign_chip_model() switches on DA9121_SUBTYPE_* values.  The
OF table provides those subvariant values, but the I2C id table
currently provides DA9121_TYPE_* values.

Make the I2C id table use the same subvariant namespace as the OF table
so non-DT I2C matches feed the expected data type into the model

Subject: [PATCH 4644/5214] ASoC: soc-core: Don't fail if device_link could not
 be created

If device_link_add() fails in snd_soc_bind_card() just skip that
driver pair and carry on.

This means that ASoC must now keep track of which components it was
able to device_link to the card->dev. The new card_device_link member
of struct snd_soc_component is non-NULL if a device_link exists.

The intent of the device link is to ensure that the machine driver
system-suspends before the component drivers, to prevent ASoC
suspend attempting to reconfigure a driver that has already suspended.

It isn't possible to create this device link if the machine driver is
a parent of the component driver or already has a device_link in the
opposite direction. In this case skip the link. A warn is placed in
kernel log since this might indicate a genuine design problem with
those two drivers (this can be downgraded to dbg in future when
people are happy that all these special drivers correctly handle their
reversed shutdown order).

Subject: [PATCH 4645/5214] blk-cgroup: protect iterating blkgs with
 blkcg->lock in blkcg_print_stat()

blkcg_print_one_stat() will be called for each blkg:
- access blkg->iostat, which is freed from rcu callback
  blkg_free_workfn();
- access policy data from pd_stat_fn(), which is freed from
  pd_free_fn(), while pd_free_fn() can be called by removing blkcg or
  deactivating policy;

Take blkcg->lock while iterating so the blkgs stay online and both
blkg->iostat and policy data for activated policies stay valid.  Use
irq-safe locking because blkcg->lock can be nested under q->queue_lock,
which is used from IRQ completion paths.

Prepare to convert protecting blkgs from request_queue with mutex.

Subject: [PATCH 4646/5214] blk-cgroup: delay freeing policy data after rcu
 grace period

Currently blkcg_print_blkgs() must hold RCU to iterate blkgs from a
blkcg, and prfill() must hold queue_lock to prevent policy data from
being freed by policy deactivation. As a consequence, queue_lock has to
be nested under RCU from blkcg_print_blkgs().

Delay freeing policy data until after an RCU grace period so prfill() can
be protected by RCU alone.

Subject: [PATCH 4647/5214] blk-cgroup: don't nest queue_lock under rcu in
 blkcg_print_blkgs()

With previous modification to delay freeing policy data after an RCU grace
period, prfill() can run under RCU instead of taking queue_lock. However,
policy teardown can still clear blkg->pd[plid] after blkcg_print_blkgs()
observes the policy enabled bit.

Load policy data once with READ_ONCE() and skip the blkg if teardown
already cleared it. Do the same in recursive stat walks for descendant
blkgs. Remove the stale BFQ debug queue_lock assertion because
blkcg_print_blkgs() no longer calls prfill() with queue_lock held. This
also lets ioc_qos_prfill() and ioc_cost_model_prfill() use IRQ-safe
ioc->lock locking without re-enabling IRQs while queue_lock is still held.

 blkg_lookup_create()

Change this in two steps:

1) hold rcu lock and do blkg_lookup() from fast path;
2) hold queue_lock directly from slow path, and don't nest it under rcu
   lock;

Prepare to convert protecting blkcg with blkcg_mutex instead of
queue_lock.

Subject: [PATCH 4650/5214] blk-cgroup: don't nest queue_lock under blkcg->lock
 in blkcg_destroy_blkgs()

The correct lock order is q->queue_lock before blkcg->lock, and in order
to prevent deadlock from blkcg_destroy_blkgs(), trylock is used for
q->queue_lock while blkcg->lock is already held, this is hacky.

Refactor blkcg_destroy_blkgs() to hold blkcg->lock only long enough to
get the first blkg and then release it. Then take q->queue_lock and
blkcg->lock in the correct order to destroy the blkg. This is a very cold
path, so the extra lock/unlock cycles are acceptable.

Also prepare to convert protecting blkcg with blkcg_mutex instead of
queue_lock.

Subject: [PATCH 4651/5214] mm/page_io: don't nest queue_lock under rcu in
 bio_associate_blkg_from_page()

Take a css reference under RCU, drop RCU, and then associate the bio with
the blkg. This avoids nesting queue_lock under RCU and prepares to protect
blkcg with blkcg_mutex instead of queue_lock.

Use css_tryget() instead of css_tryget_online() so swap writeback for
pages charged to a dying memcg still passes the dying css to
bio_associate_blkg_from_css(). That preserves the existing closest-live
ancestor fallback instead of charging those bios to the root blkg.

Subject: [PATCH 4653/5214] block: fix GFP_ flags confusion in
 bio_integrity_alloc_buf

bio_integrity_alloc_buf usage of GFP_ flags is messed up.  For one it
mixes GFP_NOFS and GFP_NOIO for neighbouring allocations, but it also
makes the allocations fail more often than needed.  That code was copied
from bio_alloc_bioset which needs to do that so that it can punt to the
rescuer workqueue, but none of that is needed for the integrity
allocations that either sits in the file system or at the very bottom
of the I/O stack.  Failing early means we'll do a fully waiting
allocation from the mempool ->alloc callback which is usually much
larger than required.

Fix this by passing a gfp_t so that the file system path can pass
GFP_NOFS and the auto-integrity code can pass GFP_NOIO, and don't
modify the allocation type except for disabling warnings.

Otherwise zone append commands will miss their integrity data.  While
this works "fine" for auto-PI, it break file system PI and non-PI

With this XFS on ZNS namespace with non-PI metadata and 512 byte sectors
with PI work, while PI 4k sector formats with PI work only when Caleb's
"block: fix integrity offset/length conversions" is applied as well.

Note that unlike regular writes, zone append does need remapping as
partitions are not supported on zoned block devices.

Subject: [PATCH 4655/5214] of: property: Fix of_fwnode_get_reference_args()
 with negative index

fwnode_property_get_reference_args() should return -ENOENT when an out
of bound index is passed. An issue arised with the OF backend because
the OF API use signed indexes while the fwnode API use unsigned ones.
When an index value greater the INT_MAX was passed to the OF backend
it got casted to a negative value and it returned -EINVAL instead of
-ENOENT. This patch add a check to of_fwnode_get_reference_args() to
catch negative index before they are passed to the OF API and return
-ENOENT right away.

This issue appeared when the following pattern was used in the LED
subsystem:

    index = fwnode_property_match_string(fwnode, "led-names", name)
    led_node = fwnode_find_reference(fwnode, "leds", index);

Unlike the same pattern with the OF API, this pattern implicitly cast
the signed return value of fwnode_property_match_string() to an
unsigned index leading to the above issue with the OF backend. It can
be argued that the return value of fwnode_property_match_string()
should be checked separately, but I think there is value in supporting
such simple and straight to the point patterns.

Subject: [PATCH 4656/5214] of: Fix RST inline emphasis warnings in of_map_id()
 kernel-doc

The @filter_np parameter descriptions in of_map_id() and of_map_msi_id()
contained the text '*filter_np' in prose. Docutils interprets a leading
'*' as the start of RST emphasis (italic), but finds no closing '*',
triggering:

  Documentation/devicetree/kernel-api:11: ./drivers/of/base.c:2134:
  WARNING: Inline emphasis start-string without end-string. [docutils]

  Documentation/devicetree/kernel-api:11: ./drivers/of/base.c:2260:
  WARNING: Inline emphasis start-string without end-string. [docutils]

Fix by wrapping '*filter_np' in double backticks (*filter_np) to
render it as an RST inline code literal, which is also the correct
kernel-doc convention for pointer expressions.

Subject: [PATCH 4660/5214] ACPICA: Unbreak tools build after switching over to
 strscpy_pad()

Commit 97f7d3f9c9ac ("ACPICA: Replace strncpy() with strscpy_pad() in
acpi_ut_safe_strncpy()") switched over the ACPICA code in the kernel to
using strscpy_pad() instead of a combination of strncpy() and manual
NUL-termination of the destination string, but it overlooked the fact
that tools also use the code in question and strscpy_pad() is not
defined in those builds.

Address that by using the original ACPICA code in non-kernel builds.

Subject: [PATCH 4663/5214] ACPI: processor_idle: Mark LPI enter functions as
 __cpuidle

When function tracing or Kprobes is enabled, entering an ACPI Low
Power Idle (LPI) state triggers the following RCU splat:

  RCU not on for: acpi_idle_lpi_enter+0x4/0xd8
  WARNING: CPU: 8 PID: 0 at include/linux/trace_recursion.h:162 function_trace_call+0x1e8/0x228

The acpi_idle_lpi_enter() function is invoked within the cpuidle
path after RCU has already been disabled for the current local CPU.
Consequently, ftrace's function_trace_call() expects RCU to be
actively watching before recording trace data, emitting a warning
if it is not.

Fix this by annotating acpi_idle_lpi_enter(), the generic __weak
stub, and the RISC-V implementation of acpi_processor_ffh_lpi_enter()
with __cpuidle. This moves these functions into the '.cpuidle.text'
section, implicitly disabling ftrace instrumentation (notrace) along
this sensitive path and preventing trace-induced RCU warnings during
idle entry.

Subject: [PATCH 4665/5214] arm64: mm: Defer read-only remap of data/bss linear
 alias

Since commit

  f2ba877402e5 ("arm64: mm: Map the kernel data/bss read-only in the linear map")

the linear alias of the .data and .bss regions is remapped read-only
early during the boot. (Note that a subsequent patch to unmap this
region entirely was reverted just before the v7.2 merge window, and will
be brought back in an improved form for the v7.3 cycle)

Fuad reports that in some cases, the KVM init code may apply relocations
to variables that reside in .data, and does so via the linear map. This
means that remapping .data read-only beforehand is a bad idea, and
results in an early boot crash.

These variables in .data are only present when CONFIG_NVHE_EL2_DEBUG or
CONFIG_NVHE_EL2_TRACING are enabled, which is why it was not spotted in
testing.

So move the remap to mark_rodata_ro(), which is a reasonable place to
put this, and ensures that it happens much later during the boot. It
also means that rodata=off is now taken into account, and so the linear
alias will remain writable in that case.

Subject: [PATCH 4666/5214] smb/client: fix security flag calculation when
 setting security descriptors

In id_mode_to_cifs_acl(), aclflag was initialized to CIFS_ACL_DACL by default.
This forced the client to request setting the DACL even when only an ownership
(chown) or group (chgrp) change was being performed.

Let build_sec_desc() do the proper flag calculation by initializing aclflag
to 0. build_sec_desc() sets the appropriate bits (CIFS_ACL_OWNER, CIFS_ACL_GROUP,
or CIFS_ACL_DACL) depending on what actually changed. During ownership transfer,
CIFS_ACL_DACL is only set if replace_sids_and_copy_aces() actually replaces the
SIDs inside any of the DACL's ACEs.

If build_sec_desc() results in aclflag being 0 (meaning no changes were mapped),
exit early to avoid sending an empty security descriptor update to the server.

Ownership (chown) and group (chgrp) modifications were being ignored when
mounting with SMB3 POSIX Extensions unless CIFS_MOUNT_CIFS_ACL or
CIFS_MOUNT_MODE_FROM_SID were also explicitly set.

Fix this by checking for posix_extensions in cifs_setattr_nounix() when
updating UID and GID, ensuring that id_mode_to_cifs_acl() is called to map
and set the ownership/group information on the server.

smb2_set_sparse() converts every FSCTL_SET_SPARSE failure to false and
marks sparse support as broken for the share. Callers therefore report
EOPNOTSUPP even for errors such as ENOSPC or EACCES, and later sparse
operations remain disabled until the share is unmounted.

Return the SMB2 ioctl error directly. Set broken_sparse_sup only for
EOPNOTSUPP, which indicates that the server does not support the request.

Update smb3_punch_hole() to propagate the error returned by
smb2_set_sparse().

Subject: [PATCH 4673/5214] spi: imx: reconfigure for PIO when DMA cannot be
 started

When spi_imx_can_dma() selects DMA, the ECSPI is configured for DMA:
spi_imx_setupxfer() sets CTRL.SMC and clears dynamic_burst, and
spi_imx_dma_transfer() programs the dynamic-burst BURST_LENGTH and the
SDMA watermarks.

If the DMA descriptor cannot be prepared (dmaengine_prep_slave_single()
returns NULL), the transfer is failed with SPI_TRANS_FAIL_NO_START and
falls back to PIO. The dynamic-burst DMA path uses its own bounce
buffers instead of the SPI core's mapping, so xfer->{tx,rx}_sg_mapped
are not set and the core's DMA->PIO retry is skipped; the driver falls
back to PIO internally. But none of the DMA-mode configuration is
undone, so the PIO transfer runs with CTRL.SMC set, the wrong burst
length and dynamic_burst cleared, and the transferred data is corrupted.

This is easily hit on i.MX8MP boards that describe ECSPI DMA in the
device tree but run SDMA on ROM firmware (no external sdma-imx7d.bin):
every ECSPI DMA prepare fails. An Infineon SLB9670 TPM on ECSPI1 then
returns shifted TPM2_GetCapability data, is flagged "field failure
mode", /dev/tpmrm0 is never created.

Set controller->fallback before re-running spi_imx_setupxfer() so the
ECSPI is reconfigured exactly like a normal PIO transfer. With
controller->fallback set, spi_imx_setupxfer() sees spi_imx_can_dma()
return false, so it clears spi_imx->usedma and reprograms the controller
(clears CTRL.SMC, restores dynamic_burst and the PIO burst length). No
explicit spi_imx->usedma = false is needed: setupxfer() already updates
it from the can_dma() result.

Fixes: faa8e404ad8e ("spi: imx: support dynamic burst length for ECSPI DMA mode")

Subject: [PATCH 4678/5214] rtc: m41t93: Add alarm support

Implement alarm feature for rtc-m41t93 by adding necessary
callbacks - set_alarm, read_alarm and alarm_irq_enable.
Enable support to configure alarm 1 out of 2 alarms present in this rtc.
Support only alarm configuration in this commit. This commit does not
implement alarm irq handling.

Use selftests/rtc/rtctest for testing. Tested by observing IRQ pin
(pin 12 of SOX18 package) on logic analyzer going low after alarm
condition is met.

Subject: [PATCH 4679/5214] rtc: m41t93: Add square wave clock provider support

Implement support to configure square wave output (SQW) of m41t93 rtc
via common clock framework clock provider api. Add clock provider
callbacks to control output frequency ranging from 1Hz to 32KHz as
supported by this rtc chip.

Use clock framework debugfs interface or clock consumer DT node to test.
Tested by measuring various frequencies on pull-up connected SWQ(7) pin
of m41t93 rtc chip using logic analyzer.

Implement watchdog feature for m41t93 rtc with 1s resolution.
Implement alarm only support (WDIOF_ALARMONLY) in this commit.
Define start, stop, ping, and set_timeout callbacks as needed
by the watchdog framework.

Use selftests/watchdog/watchdog-test kselftest for testing.
Observed IRQ pin(12) of rtc chip going low after late pinging
the watchdog.

Subject: [PATCH 4681/5214] rtc: bq32000: add delay between RTC reads

When the RTC is used on systems without a interrupt line, userspace
tools like `hwclock` fall back to a frequent polling loop to synchronize
with the edge of the next second.

On the BQ32000, this aggressive polling can temporarly lock the register
refresh cycle, because the continuous transfers prevent the hardware from
updating the buffer. This results in stale data reads or select() timeouts
in userspace.

This patch introduces a delay before reading the RTC registers in order to
provide a sufficient idle time for the hardware to sync with the register
buffer.

Subject: [PATCH 4683/5214] rtc: ds1307: Fix off-by-one issue with wday for
 rx8130

The RTC represent each weekday with a individual bit set in the WDAY
register, where the 0th bit represent the first day of the week and the
6th bit represents the last day of the week. For each passed day the
chip performs a rotary-left-shift by one to advance the weekday by one.

The tm_wday field represent weekdays by a value in the range of 0-6.

The fls() function return the bit index of the last bit set. To handle
when there are no bits set it will return 0, and if the 0th bit is set
it will return 1, and if the 1st bit is set it will return 2, and so on.

In order to make the result of the fls() function fall into the expected
range of 0-6 (instead of 1-7) this patch subtracts one from the result
(which matches how the value is written in ds1307_set_time()).

Subject: [PATCH 4684/5214] smb/client: do not account EOF extension as
 allocation

cifs_setsize() updates the local inode size after SetEOF succeeds. It also
used the new EOF as a local i_blocks estimate, but extending EOF does not
prove that the intervening range was allocated.

For example, after writing 1 MiB and then extending EOF to 10 MiB, the
client can report the file as fully allocated even though the server still
reports a much smaller AllocationSize:

        $ dd if=/dev/zero of=test bs=1M count=1
        $ truncate -s 10M test && stat -c 'size=%s blocks=%b' test
        $ stat --cached=never -c 'size=%s blocks=%b' test

        client stat:                    size=10485760 blocks=20480
        server stat:                    size=10485760 blocks=2056
        client stat after revalidation: size=10485760 blocks=2056

A later attribute revalidation may correct i_blocks, but callers such as
xfstests generic/495 invoke swapon immediately after truncate. The swapfile
hole check can therefore observe the inflated local i_blocks value and
accept a sparse file.

Do not grow i_blocks from cifs_setsize() on EOF extension.  Only clamp it
on shrink; allocation growth must come from write completion or from
server-reported AllocationSize.

With this change, EOF extension no longer makes a sparse file appear
fully allocated before the next attribute revalidation, and xfstests
generic/495 no longer accepts it through the inflated local i_blocks value.

Subject: [PATCH 4685/5214] rtc: cmos: unregister HPET IRQ handler on probe
 failure

cmos_do_probe() registers cmos_interrupt() as the HPET RTC IRQ
handler before requesting the RTC IRQ and registering the RTC
device. If either request_irq() or devm_rtc_register_device()
fails afterwards, the error path leaves the HPET RTC IRQ handler
installed. This leaves a stale handler behind and make a later
hpet_register_irq_handler() fail with -EBUSY.

Track whether the HPET handler was registered successfully and
undo the registration on the probe error path. Also mask the HPET
RTC IRQ bits to match the normal shutdown cleanup.

QueryDirectory responses today are stored in one of two fixed

borrowed from server struct and are not sufficient for large-sized

With this change we will now define a new buffer type specifically

be allocated by kmalloc and freed by kfree.

Subject: [PATCH 4688/5214] net: airoha: Fix off-by-one in
 airoha_tc_remove_htb_queue()

airoha_tc_htb_alloc_leaf_queue() computes the HTB QoS channel index
as opt->classid % AIROHA_NUM_QOS_CHANNELS and stores it in qos_sq_bmap.
However, airoha_tc_remove_htb_queue() clears the HTB configuration
using queue + 1 as the channel index, causing an off-by-one error.
Use queue directly as the QoS channel index to match the allocation
logic.

Subject: [PATCH 4689/5214] net: airoha: fix netif_set_real_num_tx_queues for
 sparse QoS channels

airoha_tc_htb_alloc_leaf_queue() assigns queue IDs based on the channel
index (opt->qid = AIROHA_NUM_TX_RING + channel), but updates
real_num_tx_queues with a simple increment (num_tx_queues + 1). When QoS
channels are allocated sparsely (e.g., channels 0 and 3 without 1 and
2), the returned qid can exceed real_num_tx_queues, causing out-of-bounds
accesses in the networking stack.
For example, allocating channel 0 then channel 3 results in
real_num_tx_queues = 34 but qid = 35, which is out of range [0, 34).
Fix this by computing real_num_tx_queues based on the highest active
channel index rather than using a simple counter, in both the allocation
and deletion paths.

Subject: [PATCH 4690/5214] net: ixp4xx_hss: fix duplicate HDLC netdev
 allocation

ixp4xx_hss_probe() allocates two HDLC netdevs. The first one is stored
in ndev, initialized, and registered with register_hdlc_device(). The
second one is stored in port->netdev and later used by the remove path
for unregister_hdlc_device() and free_netdev().

This means that the registered netdev is not the same object that is
unregistered and freed on remove. It also leaks the first allocation if
the second alloc_hdlcdev() call fails, and the first allocation is not
checked before ndev is used.

Older code allocated the HDLC netdev only once and stored the same object
in both the local variable and port->netdev. The buggy conversion split
this into two alloc_hdlcdev() calls. A later rename changed the local
variable name to ndev, but the underlying mismatch remained.

Fix this by allocating the HDLC netdev only once and assigning the same
object to port->netdev.

led_classdev_register_ext() only reads init_data.devicename - it never

Subject: [PATCH 4692/5214] net: dsa: mxl862xx: avoid unaligned 16-bit access
 in api_wrap

The MXL862XX_API_* macros pass the address of a stack-allocated, __packed
firmware-ABI struct to mxl862xx_api_wrap() as a void *. The struct has an
alignment of 1, so the compiler is free to place it at an odd address.

mxl862xx_api_wrap() reinterprets that buffer as a __le16 * and accesses it
with data[i], for which the compiler assumes the natural 2-byte alignment
of __le16 and emits aligned 16-bit loads/stores (e.g. lhu/sh on MIPS).
When the buffer lands on an odd address these fault on architectures that
do not support unaligned access, such as MIPS32.

-Waddress-of-packed-member does not catch this: the packed origin is
laundered through the void * parameter, so the cast inside api_wrap looks
alignment-safe to the compiler and no warning is emitted.

Use get_unaligned_le16()/put_unaligned_le16() for the three 16-bit word
accesses. The byte accesses (*(u8 *)&data[i], crc16()) are already safe
and are left unchanged.

Subject: [PATCH 4693/5214] net: dsa: mxl862xx: fix use-after-free of DSA ports
 in crc_err_work

Upon an MDIO CRC error mxl862xx_crc_err_work_fn() walks the DSA ports
and closes the CPU port conduits:

	dsa_switch_for_each_cpu_port(dp, priv->ds)
		dev_close(dp->conduit);

mxl862xx_remove() unregisters the switch before cancelling this work:

	set_bit(MXL862XX_FLAG_WORK_STOPPED, &priv->flags);
	cancel_delayed_work_sync(&priv->stats_work);
	dsa_unregister_switch(ds);
	mxl862xx_host_shutdown(priv);

dsa_unregister_switch() frees the dsa_port objects. If a CRC error
schedules the work during teardown it can run after the ports have been
freed and dereference freed memory.

Guard the port walk with MXL862XX_FLAG_WORK_STOPPED, which is already set
before dsa_unregister_switch(). DSA tears the ports down under
rtnl_lock(), so checking the flag under rtnl_lock() means the work either
runs before teardown and sees valid ports, or runs afterwards, observes
the flag and skips the walk. This mirrors the host_flood_work handler,
which skips torn-down ports under rtnl_lock().

Subject: [PATCH 4694/5214] net: mana: Fall back to standard MTU when PF
 reports adapter_mtu of 0

Commit d7709812e13d ("net: mana: hardening: Validate adapter_mtu from
MANA_QUERY_DEV_CONFIG") rejected any adapter_mtu value smaller than
ETH_MIN_MTU + ETH_HLEN, including 0, returning -EPROTO and failing
mana_probe().

Some older PF firmware versions still in the field report
adapter_mtu as 0 in the MANA_QUERY_DEV_CONFIG response. With the
hardening check in place, the MANA VF driver now fails to load on
those hosts, breaking networking entirely for guests.

MANA hardware always supports the standard Ethernet MTU. Treat a
reported adapter_mtu of 0 as "the PF did not advertise a value" and
fall back to ETH_FRAME_LEN, the same value used for the pre-V2
message version path. Only jumbo frames remain unavailable until
the PF reports a valid MTU.

Other small-but-nonzero bogus values are still rejected, preserving
the original protection against the unsigned-subtraction wrap that
would otherwise let ndev->max_mtu underflow to a huge value.

Subject: [PATCH 4695/5214] octeontx2-af: npc: cn20k: Fix subbank free list
 indexing for search order

subbank_srch_order[i] is the physical subbank at search-order slot i,
so each subbank's arr_idx must be i (its slot), not
subbank_srch_order[sb->idx].  The old logic mis-keyed xa_sb_free
and broke allocation traversal order.

Populate arr_idx and xa_sb_free in a single pass over the search
order after subbank structs are initialized.

On RTL8127A connected to a link partner that advertises 10000baseT
speed cannot be changed to anything other than 10000baseT as 10GbE

Subject: [PATCH 4697/5214] net: airoha: fix BQL underflow in shared QDMA TX
 ring

When multiple netdevs share a QDMA TX ring and one device is stopped,
netdev_tx_reset_subqueue() zeroes that device's BQL counters while its
pending skbs remain in the shared HW TX ring. When NAPI later completes
those skbs via netdev_tx_completed_queue(), the already-zeroed
dql->num_queued counter underflows.

Fix the issue:
- Remove netdev_tx_reset_subqueue() from airoha_dev_stop() so pending
  skbs are completed naturally by NAPI with proper BQL accounting.
- Rework airoha_qdma_tx_cleanup() to disable TX DMA, flush BQL
  counters, DMA-unmap and free all pending skbs while skb->dev
  references are still valid. Use a per-queue flushing flag checked
  under q->lock in airoha_dev_xmit() to prevent races between teardown
  and transmit. Call airoha_qdma_stop_napi() before
  airoha_qdma_tx_cleanup() at the call sites.
- Move DMA engine start into probe. Split DMA teardown so TX DMA is
  disabled in airoha_qdma_tx_cleanup() and RX DMA in
  airoha_qdma_cleanup().
- Remove qdma->users counter since DMA lifetime is now tied to
  probe/cleanup rather than per-netdev open/stop.

Subject: [PATCH 4698/5214] net: wwan: t7xx: destroy DMA pool on CLDMA late
 init failure

t7xx_cldma_late_init() creates md_ctrl->gpd_dmapool before
initializing the TX and RX rings. If any ring initialization
fails, the error path frees the already initialized rings but
leaves the DMA pool allocated.

Destroy md_ctrl->gpd_dmapool on the late-init failure path
to avoid leaking the DMA pool.

 leaks

CGX per-lmac debugfs seq readers obtained struct rvu via
pci_get_drvdata(pci_get_device(..., PCI_DEVID_OCTEONTX2_RVU_AF, ...)),
which leaks a PCI device reference on every read. Store rvu and the CGX

fwdata so lmac_id matches the other CGX debugfs entries.

Subject: [PATCH 4701/5214] net: mvneta: re-enable percpu interrupt on resume

On Marvell MPIC platforms (Armada 370/XP/38x), mvneta uses a percpu
IRQ disable/enable scheme for NAPI: the ISR (mvneta_percpu_isr) calls
disable_percpu_irq() to mask the MPIC per-CPU interrupt and schedules
NAPI poll, which calls enable_percpu_irq() on completion to unmask.

If suspend occurs while NAPI poll is pending (between
disable_percpu_irq in the ISR and enable_percpu_irq in poll
completion), the interrupt is never re-enabled:

  1. mvneta_percpu_isr: disable_percpu_irq() + napi_schedule()
     => MPIC masked, percpu_enabled cpumask bit cleared
  2. NAPI poll does not complete before suspend proceeds
     (on PREEMPT_RT this is highly likely since softirqs run in
     ksoftirqd which gets frozen; on non-RT it can happen when
     softirq processing is deferred to ksoftirqd)
  3. mvneta_stop_dev => napi_disable(): cancels the pending poll
     without executing the completion path
  4. suspend_device_irqs => IRQCHIP_MASK_ON_SUSPEND: masks MPIC
     (already masked, but records IRQS_SUSPENDED)
  5. Resume: mpic_resume checks irq_percpu_is_enabled() => false
     (bit was cleared in step 1) => skips unmask
  6. mvneta_start_dev only restores device-level INTR_NEW_MASK,
     does not touch the MPIC per-CPU mask

Result: MPIC per-CPU interrupt stays masked permanently. The NIC
generates interrupts (INTR_NEW_CAUSE != 0) but the CPU never
receives them, causing complete loss of network connectivity.

Fix by calling on_each_cpu(mvneta_percpu_enable) in the resume path
to unconditionally unmask the MPIC per-CPU interrupt regardless of
pre-suspend state.

Subject: [PATCH 4702/5214] geneve: gate GRO hint in geneve_gro_complete() on
 gs->gro_hint

geneve_gro_receive() reads the GRO hint through geneve_sk_gro_hint_off(),
which honours it only when the socket enabled IFLA_GENEVE_GRO_HINT
(gs->gro_hint). geneve_gro_complete() instead calls the low-level
geneve_opt_gro_hint_off() and acts on the hint unconditionally.

On a tunnel without the hint, receive aggregates the frames as plain
ETH_P_TEB while complete still honours an attacker-supplied hint option: it
inflates gh_len by gro_hint->nested_hdr_len (u8) and redirects the dispatch
type, so the inner gro_complete handler runs at nhoff + gh_len, an offset
receive never pulled nor validated, reading out of bounds of the skb head:

  BUG: KASAN: slab-out-of-bounds in ipv6_gro_complete (net/ipv6/ip6_offload.c:196)
  Read of size 1 at addr ffff88800fe91980 by task exploit/153
   ipv6_gro_complete (net/ipv6/ip6_offload.c:196)
   geneve_gro_complete (drivers/net/geneve.c:965)
   udp_gro_complete (net/ipv4/udp_offload.c:940)
   inet_gro_complete (net/ipv4/af_inet.c:1621)
   __gro_flush (net/core/gro.c:306)

Gate the complete path on gs->gro_hint too via geneve_sk_gro_hint_off(), so
both paths agree. Tunnels that enable the hint are unaffected.

Subject: [PATCH 4703/5214] geneve: validate inner network offset in
 geneve_gro_complete()

Even with both paths gated on gs->gro_hint, geneve_gro_complete()
re-derives the inner dispatch type and length from the packet and the
current gs->gro_hint, independently of geneve_gro_receive(). The two can
disagree if gs->gro_hint flips under a concurrent geneve_quiesce()/
geneve_unquiesce() (sk_user_data is NULL across a synchronize_net()), or if
the re-read option bytes differ from the ones receive parsed.

geneve_gro_receive() already records the inner network header position in
NAPI_GRO_CB()->inner_network_offset. Have geneve_gro_complete() compute the
offset it is about to dispatch at, adding ETH_HLEN in the ETH_P_TEB case
where eth_gro_complete() steps over the inner MAC header, and bail out if
it lands past inner_network_offset.

Use a lower bound rather than exact equality: between gh_len and the inner
L3 header, geneve_gro_receive() may also have pulled an inner VLAN tag
(vlan_gro_receive() advances the recorded offset past it), which only moves
inner_network_offset further out. A valid frame therefore always satisfies
inner_nh <= inner_network_offset, while a gh_len inflated by a hint
gro_receive() did not honour dispatches past the validated inner header,
i.e. the out-of-bounds completion. Only the latter is rejected.

kalmia_rx_fixup() computes usb_packet_length = skb->len - (2 *
KALMIA_HEADER_LENGTH) as a u16, guarded only by a pre-loop check that
skb->len is at least KALMIA_HEADER_LENGTH, which is 6. A device can
deliver a short bulk-IN frame with skb->len in the 6 to 11 range, or
leave a short trailing remainder on a later loop iteration. Either case
underflows usb_packet_length to about 65530.

That bypasses the usb_packet_length < ether_packet_length truncation path.
The device-supplied ether_packet_length, a le16 up to 65535 read from
header_start[2], then drives a memcmp() and the following skb_trim() and
skb_pull() past the end of the rx buffer. The rx buffer is hard_mtu * 10,
which is 14000 bytes. That is an out of bounds read.

Require both the start and end framing headers to be present before
subtracting them, on every loop iteration.

Subject: [PATCH 4707/5214] net/tcp-ao: fix use-after-free of key in del_async
 path

In tcp_ao_delete_key(), the del_async path skips the current_key
and rnext_key validity checks present in the synchronous path,
assuming these pointers are always NULL on LISTEN sockets.  However,
if a key was added with set_current=1/set_rnext=1 while the socket
was in CLOSE state, current_key and rnext_key will be non-NULL
after listen() transitions the socket to LISTEN.

When such a key is deleted with del_async=1, hlist_del_rcu() and
call_rcu() free the key without clearing the dangling pointers.
After the RCU grace period, getsockopt(TCP_AO_INFO) dereferences
current_key->sndid and rnext_key->rcvid from freed slab memory.

Clear current_key and rnext_key in the del_async path when they
reference the key being deleted.

Subject: [PATCH 4708/5214] net: sungem: fix probe error cleanup

gem_init_one() calls gem_remove_one() when register_netdev() fails.
gem_remove_one() unregisters and frees resources owned by the net_device,
including the DMA block, MMIO mapping, PCI regions, and the net_device
itself. gem_init_one() then falls through to its own cleanup labels and
frees the same resources again.

Keep the register_netdev() error path in gem_init_one(): clear drvdata so
PM/remove paths do not see a half-registered device, remove the NAPI
instance added during probe, and let the existing cleanup labels release
the resources once.

The issue was found by a local static-analysis checker for probe error
paths. The reported path was manually inspected before sending this fix.

Compile-tested with CONFIG_SUNGEM=y. Runtime testing was not performed
because no sungem hardware is available.

Subject: [PATCH 4710/5214] net: ethernet: sunplus: spl2sw: fix phy_node
 refcount leak in remove

mac->phy_node is acquired via of_parse_phandle() in spl2sw_probe() and
stored in the mac private data, transferring ownership of the
device_node reference to mac. On driver removal, spl2sw_phy_remove()
disconnects the PHY but never drops that reference, so each
probe-then-remove cycle leaks one of_node refcount per port permanently.

Drop the reference after phy_disconnect(). While at it, remove the
redundant inner "if (ndev)" check; comm->ndev[i] was just verified
non-NULL on the line above.

Compile-tested only; no SP7021 hardware available.

Subject: [PATCH 4713/5214] LoongArch: Add THREAD_INFO_IN_TASK implementation

Like other architectures such as x86, arm64, riscv, powerpc and s390,
select THREAD_INFO_IN_TASK for LoongArch to move thread_info off the
stack into task_struct. This follows modern kernel standards and also
makes the system more secure.

With this patch, thread_info is included in task_struct at an offset
of 0 instead of being placed at the bottom of the kernel stack. Thus,
the $tp register points to both thread_info and task_struct.

To support this, introduce a per-CPU variable cpu_tasks to store the
pointer to the current task_struct. This decouples the recovery	of the
$tp register from the stack pointer during exception entry.

Then initialize cpu_tasks for the primary and secondary CPUs during
arch-specific setup and SMP boot paths. To eliminate the dangerous
windows during the early initialization where the cpu_tasks remains
uninitialized, set_current() is invoked as early as possible in both
setup_arch() and start_secondary(). This ensures the $tp recovery
barrier is armed in case any early boot exceptions or kernel panics
occur.

Modify SAVE_SOME and handle_syscall to restore the $tp register from
cpu_tasks, and also use the la_abs absolute addressing for cpu_tasks
access in assembly to bypass the relocation limits within exception
handling sections. By advancing the preservation of u0 in SAVE_SOME,
we reuse the PERCPU_BASE_KS value in u0 for the cpu_tasks calculation,
effectively eliminating a duplicate csrrd instruction execution on SMP
platforms.

Update <asm/switch_to.h> and <kernel/switch.S> to fully support the
CONFIG_THREAD_INFO_IN_TASK feature.

Remove the obsolete next_ti argument from __switch_to(), which shifts
the remaining arguments ahead in the calling convention (sched_ra from
a3 to a2, and sched_cfa from a4 to a3). Under the new configuration,
__switch_to() now directly derives the thread pointer ($tp) from the
next task_struct pointer in a1.

To preserve the optimal and clean "move tp, a1" path for 64-bit kernels,
the thread pointer ($tp) is assigned directly from a1 in the core path.
For 32-bit kernels, where a1 carries a 2000-byte structural pointer bias
at entry, an explicit adjustment "PTR_ADDI tp, tp, -TASK_STRUCT_OFFSET"
is introduced at the function exit.

In the context of __switch_to(), local interrupts are disabled, and the
kernel is in a critical switching phase where handling any synchronous
exception is practically impossible and prohibited.

If any synchronous exception or watchpoint does trigger in this narrow
window, it constitutes a fatal double fault and the kernel is expected
to die/panic immediately anyway. Therefore, the temporary biased value
in $tp is safe and acceptable here.

Additionally, evaluate the stack lookup as a single load instruction
"LONG_LPTR t0, a1, (TASK_STACK - TASK_STRUCT_OFFSET)", this perfectly
satisfies both 32-bit and 64-bit kernels. Using the "next" pointer in
a1 as the base register, rather than $tp, effectively unchains the data
dependency (RAW hazard) from the preceding move instruction, maximizing
the instruction-level parallelism and superscalar execution efficiency
while naturally adapting the structural shift.

With CONFIG_THREAD_INFO_IN_TASK enabled, the kernel stack life cycle is
decoupled from task_struct and can be freed concurrently.

Currently, show_stacktrace() reads raw stack data via __get_addr() and
subsequently calls show_backtrace() to unwind the frame, without holding
any reference to the target task's stack. If show_stacktrace() is called
on a concurrently exiting task, it could attempt to read from a freed or
reallocated kernel stack. This introduces a severe use-after-free (UAF)
read risk or kernel panics.

Wrap the entire stack inspection process inside show_stacktrace() with
a try_get_task_stack() and put_task_stack() pair. This ensures the task
stack remains pinned safely during both the raw stack data dump loop and
the subsequent stack unwinding phase.

Also, ensure that the task pointer is initialized to "current" early if
it is NULL, so that try_get_task_stack() always operates on a valid task
reference.

Subject: [PATCH 4714/5214] LoongArch: Add PIO for early access before ACPI PCI
 root register

For ACPI system we suppose the ISA/LPC PIO range is registered together
with PCI root bridge. But the fact is there may be some early access to
the ISA/LPC PIO range before ACPI PCI root register (most of them are
due to abnormal BIOS). Unconditionally register the ISA/LPC PIO range
usually causes ACPI PCI root register fail because of the address range
confliction. So we add a pair of helpers: acpi_add_early_pio() to add
PIO for early access, and acpi_remove_early_pio() to remove PIO before
PCI root register. Since acpi_remove_early_pio() may be called multiple
times, we add an acpi_pio flag to ensure PIO be removed only once.

Subject: [PATCH 4715/5214] LoongArch: Report dying CPU to RCU in
 stop_this_cpu()

This is a port of MIPS commit 9f3f3bdc6d9dac1 ("MIPS: smp: report dying
CPU to RCU in stop_this_cpu()"). smp_send_stop() parks all secondary
CPUs in stop_this_cpu(). And the function marks the CPU offline for the
scheduler via set_cpu_online(false) but never informs RCU, so RCU keeps
expecting a quiescent state from CPUs that are now spinning forever with
interrupts disabled.

As long as nothing waits for an RCU grace period after smp_send_stop()
this is harmless, which is why it went unnoticed. However, since commit
91840be8f710370 ("irq_work: Fix use-after-free in irq_work_single() on
PREEMPT_RT"), irq_work_sync() calls synchronize_rcu() on architectures
without an irq_work self-IPI, i.e. where arch_irq_work_has_interrupt()
returns false. Any irq_work_sync() issued in the reboot/shutdown/halt
path after smp_send_stop() then blocks on a grace period that can never
complete, hanging the reboot:

  WARNING: CPU: 0 PID: 15 at kernel/irq_work.c:144 irq_work_queue_on
  ...
  rcu: INFO: rcu_sched detected stalls on CPUs/tasks:
  rcu: Offline CPU 1 blocking current GP.
  rcu: Offline CPU 2 blocking current GP.
  rcu: Offline CPU 3 blocking current GP.

This issue needs some hacks to reproduce, and it was not noticed on
LoongArch because arch_irq_work_has_interrupt() usually returns true.

Call rcutree_report_cpu_dead() once interrupts are disabled, mirroring
the generic CPU-hotplug offline path, so RCU stops waiting on the parked
CPUs and grace periods can still complete. LoongArch shuts down all CPUs
here without going through the CPU-hotplug mechanism, so this report is
not otherwise issued.

Subject: [PATCH 4717/5214] LoongArch: Fix missing dirty page tracking in
 {pte,pmd}_wrprotect()

When hardware page table walker (PTW) is enabled on LoongArch, the CPU
may set _PAGE_DIRTY directly in the page table entry during a write TLB
miss, without going through the software TLB store handler. The software
TLB store handler (tlbex.S:254) sets both _PAGE_DIRTY and_PAGE_MODIFIED
together:

    ori t0, t0, (_PAGE_VALID | _PAGE_DIRTY | _PAGE_MODIFIED)

Since hardware PTW only sets _PAGE_DIRTY, the software-only bit, i.e.
_PAGE_MODIFIED is left unchanged. This creates a window where a PTE has
_PAGE_DIRTY set (hardware knows the page is dirty) but _PAGE_MODIFIED
clear (software is unaware).

When fork()/clone() triggers copy-on-write, __copy_present_ptes() calls
pte_wrprotect(), which unconditionally clears both the _PAGE_WRITE and
_PAGE_DIRTY bits:

    pte_val(pte) &= ~(_PAGE_WRITE | _PAGE_DIRTY);

Since _PAGE_MODIFIED was never set, the dirtiness information is lost
completely. Subsequently, when memory pressure triggers page reclaim,
page_mkclean() / try_to_unmap() sees the page as clean (i.e. pte_dirty()
returns false) and the page may be freed without writeback, causing data
corruption.

Fix this by propagating the _PAGE_DIRTY bit to the _PAGE_MODIFIED bit in
both pte_wrprotect() and pmd_wrprotect() before clearing writeable bits:

    if (pte_val(pte) & _PAGE_DIRTY)
        pte_val(pte) |= _PAGE_MODIFIED;

The pmd_wrprotect() fix handles the CONFIG_TRANSPARENT_HUGEPAGE case,
where pmd entries need the same treatment.

This ensures the software dirty tracking bit (checked by pte_dirty() and
pmd_dirty(), which read both the _PAGE_DIRTY and _PAGE_MODIFIED bits) is
preserved across fork COW write-protection.

The issue was found by the LTP madvise09 test case, which exercises page
reclaim after "madvise(MADV_FREE), write and fork" operation sequence on
private anonymous mappings.

Subject: [PATCH 4720/5214] LoongArch: BPF: Fix outdated tail call comments

The current LoongArch BPF JIT implementation hardcodes the number of
prologue instructions skipped during a tail call as a magic number '7'
in the jirl instruction. However, the accompanying comment explaining
this offset is completely outdated. It inaccurately states that only
a single TCC initialization instruction is bypassed, but in reality,
multiple setup slots are skipped, so fix these outdated comments in
__build_epilogue().

While at it, refine the comments in build_prologue() to describe the
skipped setup slots (RA saving, fentry nops, and the TCC register slot)
using proper dynamic tracing context. Also, remove the magic number '7'
by introducing descriptive macros to formally define the prologue layout
and make the tail call jump offset self-documenting.

Subject: [PATCH 4721/5214] LoongArch: BPF: Fix off-by-one error in tail call

The current code updates the tail call counter (TCC) using a pre-increment
approach, it stores the incremented value back to memory before performing
any boundary or target validation checks.

This causes two major issues:
1. When a tail call fails because the target program is NULL, the TCC is
   incorrectly incremented and saved in memory anyway.
2. This dummy increment implicitly consumes one slot of the allowed tail
   call budget. As a result, the subsequent loop reaches the maximum limit
   prematurely, leading to a test failure where the actual loop count is
   32 instead of the expected 33.

Fix this by deferring the counter update. Change the branch condition to
BPF_JSGE (greater or equal) so that we check the boundary first. The TCC
is only incremented and stored back to memory after the boundary check
and the NULL-target check both pass.

Before:

  $ sudo ./test_progs -t tailcalls/tailcall_3
  ...
  test_tailcall_count:FAIL:tailcall count unexpected tailcall count: actual 32 != expected 33
  ...
  #465/3   tailcalls/tailcall_3:FAIL
  #465     tailcalls:FAIL

After:

  $ sudo ./test_progs -t tailcalls/tailcall_3
  #465/3   tailcalls/tailcall_3:OK
  #465     tailcalls:OK
  Summary: 1/1 PASSED, 0 SKIPPED, 0 FAILED

Subject: [PATCH 4722/5214] LoongArch: BPF: Inline bpf_get_current_task/_btf()
 helpers

The pointer to task_struct is always available in the $tp register, so
the calls to bpf_get_current_task() and bpf_get_current_task_btf() can
be inlined into a single move instruction.

(1) Here is the sample test.c:

  #include <linux/bpf.h>
  #include <bpf/bpf_helpers.h>

  SEC("raw_tp/sys_enter")
  long test_task(void *ctx)
  {
	  return (long)bpf_get_current_task();
  }
  char _license[] SEC("license") = "GPL";

(2) Here are the test steps:

  sudo yum install libbpf-devel kernel-devel bpftool
  clang -target bpf -O2 -c test.c -o test.o
  sudo sysctl -w net.core.bpf_jit_enable=1
  sudo bpftool prog show name test_task
  sudo rm -f /sys/fs/bpf/test_task
  sudo bpftool prog load test.o /sys/fs/bpf/test_task
  ID=$(sudo bpftool prog show pinned /sys/fs/bpf/test_task | grep -oE '^[0-9]+')
  sudo bpftool prog dump jited id $ID

(3) Here are the test results:

Before: 6 instructions

  ...
  64:	lu12i.w	$t1, 1093
  68:	ori	$t1, $t1, 3320
  6c:	lu32i.d	$t1, 0
  70:	lu52i.d	$t1, $t1, -1792
  74:	jirl	$ra, $t1, 0
  78:	move	$a5, $a0
  ...

After: 1 instruction

  ...
  64:	move	$a5, $tp
  ...

This is similar with commit 2bb138cb20a6 ("bpf, arm64: Inline

Subject: [PATCH 4723/5214] LoongArch: BPF: Inline bpf_get_smp_processor_id()
 helper

The pointer to thread_info is always available in the $tp register, so
the call to bpf_get_smp_processor_id() can be inlined into a single load
instruction.

(1) Here is the sample test.c:

  #include <linux/bpf.h>
  #include <bpf/bpf_helpers.h>

  SEC("raw_tp/sys_enter")
  int test_cpuid(void *ctx)
  {
	  return bpf_get_smp_processor_id();
  }
  char _license[] SEC("license") = "GPL";

(2) Here are the test steps:

  sudo yum install libbpf-devel kernel-devel bpftool
  clang -target bpf -O2 -c test.c -o test.o
  sudo sysctl -w net.core.bpf_jit_enable=1
  sudo bpftool prog show name test_cpuid
  sudo rm -f /sys/fs/bpf/test_cpuid
  sudo bpftool prog load test.o /sys/fs/bpf/test_cpuid
  ID=$(sudo bpftool prog show pinned /sys/fs/bpf/test_cpuid | grep -oE '^[0-9]+')
  sudo bpftool prog dump jited id $ID

(3) Here are the test results:

Before: 6 instructions

  ...
  64:	lu12i.w	$t1, 1213
  68:	ori	$t1, $t1, 1680
  6c:	lu32i.d	$t1, 0
  70:	lu52i.d	$t1, $t1, -1792
  74:	jirl	$ra, $t1, 0
  78:	move	$a5, $a0
  ...

After: 1 instruction

  ...
  64:	ld.wu	$a5, $tp, 16
  ...

This is similar with commit 2ddec2c80b44 ("riscv, bpf: inline
bpf_get_smp_processor_id()").

Subject: [PATCH 4727/5214] selftests/bpf: Add get_preempt_count() support for
 LoongArch

There is no LoongArch support for get_preempt_count() currently and its
fallback path always returns 0, just add it so that bpf_in_interrupt(),
bpf_in_nmi(), bpf_in_hardirq(), bpf_in_serving_softirq(), bpf_in_task()
work for LoongArch as well.

The latest kernels select CONFIG_THREAD_INFO_IN_TASK, it can just read
preempt_count from the thread_info which is embedded within task_struct.

With this patch, "./test_progs -t exe_ctx" passes on LoongArch.

Subject: [PATCH 4733/5214] ALSA: usb-audio: avoid kobject path lookup in
 DualSense match

The DualSense jack-detection input handler verifies that a matching input
device belongs to the same physical controller by building kobject path
strings for both the input device and the USB audio device, then comparing
the path prefix.

This was observed when a weak physical connection caused the controller
to rapidly disconnect and reconnect. During that repeated hotplug,
snd_dualsense_ih_match() can run while the controller's USB device is
being disconnected. kobject_get_path() walks ancestor kobjects and
dereferences their names; if the USB device kobject name is no longer
valid, this can fault in strlen():

  RIP: 0010:strlen+0x10/0x30
  Call Trace:
   kobject_get_path+0x34/0x150
   snd_dualsense_ih_match+0x49/0xd0 [snd_usb_audio]
   input_register_device+0x566/0x6a0
   ps_probe+0xb89/0x1590 [hid_playstation]

The same ownership check can be done without building kobject path
strings. The input device is parented below the HID device, USB interface
and USB device, so walking the input device parent chain and comparing
against the mixer USB device preserves the check without dereferencing
kobject names during disconnect.

Subject: [PATCH 4734/5214] ALSA: hda: Add Lenovo Legion 7i 16IAX7 17AA3874
 quirk

Lenovo Legion 7i 16IAX7 systems with Realtek ALC287 codec SSID
17aa:3874 and CSC3551/CS35L41 speaker amps do not provide the
required CS35L41 _DSD properties in ACPI.

Without a quirk, cs35l41-hda fails probing the amps with missing
cirrus,dev-index / Platform not supported errors, leaving the built-in
speakers silent.

This model is similar to the already-supported 17AA386F Legion 7i
16IAX7 variant. Add the Realtek ALC287 quirk to select
ALC287_FIXUP_CS35L41_I2C_2 and add 17AA3874 to the CS35L41 property
table using the same two-amp external-boost configuration.

Tested on a Lenovo Legion 7 16IAX7 with Ubuntu 7.0.0-22-generic. Both
CSC3551 CS35L41 amps probe and bind, firmware loads, calibration
applies, built-in speaker playback works, and the cirrus,dev-index
failure is gone.

qc_usb_audio_probe() allocates svc->uaudio_svc_hdl separately from the
uaudio_qmi_svc object.

qmi_handle_release() releases the resources owned by an initialized QMI
handle, but does not free the memory containing the struct qmi_handle
itself. The probe error path and the remove path currently release the
handle and then free svc, losing the last pointer to the separately
allocated handle.

This leaks one struct qmi_handle on each affected probe unwind and on
each successful probe/remove cycle.

Free the handle after qmi_handle_release() in both paths.

Subject: [PATCH 4736/5214] ALSA: firewire: isight: bound the sample count to
 the packet payload

isight_packet() takes the frame count from the device iso packet and
checks it only against the device claimed iso length.

	count = be32_to_cpu(payload->sample_count);
	if (likely(count <= (length - 16) / 4))
		isight_samples(isight, payload->samples, count);

length is the iso header data_length. It can be up to 0xffff. So the
gate allows a count up to about 16379. isight_samples() then copies
count frames out of payload->samples into the PCM DMA buffer.

payload->samples holds only 2 * MAX_FRAMES_PER_PACKET values. The
device multiplexes two samples per frame. A count past
MAX_FRAMES_PER_PACKET reads past the payload. A count past the buffer
size writes past runtime->dma_area. The smallest PCM buffer is larger
than MAX_FRAMES_PER_PACKET. Bounding the count to MAX_FRAMES_PER_PACKET
keeps both the read and the write in range.

A malicious or faulty Apple iSight on the FireWire bus reaches this
during a normal capture.

Add the MAX_FRAMES_PER_PACKET bound to the gate.

Subject: [PATCH 4738/5214] platform/x86: amd-pmc: Fix S0i3 wakeup with
 alarmtimer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It was reported that suspend-then-hibernate stopped working with modern
systemd versions on AMD Cezanne systems. The reason for this breakage
was because systemd switched to using alarmtimer instead of the wakealarm
sysfs file.

On AMD Cezanne systems, amd_pmc_verify_czn_rtc() programs a secondary
timer with the alarm time. This was introduced by
commit 59348401ebed ("platform/x86: amd-pmc: Add special handling for
timer based S0i3 wakeup"). However, this function uses rtc_read_alarm(),
which only reads the aie_timer, not the next expiring timer from the
timerqueue.

When both alarmtimer and wakealarm are active, the first expiring timer
might be the alarmtimer, but amd_pmc_verify_czn_rtc() would only see
the aie_timer, potentially missing the earlier alarm.

Switch to rtc_read_next_alarm() to read whichever timer will fire next.
Also handle -ENOENT (no alarm pending) explicitly as a non-error case.

The CONFIG_RTC_DRV_DS1307_HWMON macro was removed in favor of
CONFIG_HWMON in commit 6b583a64fd1e ("rtc: ds1307: simplify hwmon
config"), but a reference to it remained in a comment. Correct this
reference.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.

Subject: [PATCH 4740/5214] spi: sh-msiof: abort transfers when reset times out

sh_msiof_spi_reset_regs() asserts TX/RX reset and polls until the reset
bits clear, but the poll result is ignored. sh_msiof_transfer_one() can
therefore continue programming a transfer after the controller did not
leave reset.

Return the reset poll result from the helper and abort the transfer on
timeout, matching the existing transfer path's error-return style.

 wakeup

ACPI_TAD_AC_WAKE is a non-zero bit definition, so testing the macro
itself is always true. As a result, every TAD device is initialized as
a system wakeup device, including RTC-only devices and devices whose
wake capability bits were cleared because _PRW is absent.

Test the capability value returned by _GCP instead. This keeps
RTC-only TAD devices usable without advertising a wakeup capability
that the firmware does not provide.

Subject: [PATCH 4744/5214] ASoC: fsl_asrc_dma: fix eDMA maxburst misalignment
 with channel count

The back-end consumes data in units of the number of channels. When the
maxburst value is not evenly divisible by the channel count, the DMA
transfer length does not align with the FIFO frame boundary, causing
wrong data to be copied and audible noise at the end of the stream.

This is specific to eDMA: eDMA only responds to DMA requests from the
back-end, whereas SDMA handles requests from both the front-end and the
back-end and is not affected.

For eDMA, when the back-end maxburst is not evenly divisible by the
channel count, align it to the nearest valid boundary:
- If maxburst >= channel count, override to the channel count so each
  transfer corresponds to exactly one audio frame.
- If maxburst < channel count, override to 1 to avoid partial-frame
  transfers.

Retain the original maxburst for SDMA or when it already aligns with
the channel count.

Subject: [PATCH 4745/5214] net: udp_tunnel: prevent double queueing in
 udp_tunnel_nic_device_sync

Yue Sun reported a use-after-free and debugobjects warning in
udp_tunnel_nic_device_sync_work() during concurrent device operations.

The workqueue core clears the internal pending bit before invoking the
worker. At that point, a concurrent thread can queue the work again.
When the already running worker eventually clears the work_pending flag
to 0, it mistakenly clears the flag for the newly queued instance.
udp_tunnel_nic_unregister() then observes work_pending as 0 and frees
the structure while the second work item is still active in the queue,
leading to UAF.

Fix this by returning early in udp_tunnel_nic_device_sync() if
work_pending is already set, preventing redundant work queueing.

Subject: [PATCH 4746/5214] openvswitch: conntrack: annotate ct limit hlist
 traversal

ct_limit_set() is documented as being called with ovs_mutex held. It
walks the ct limit hlist with hlist_for_each_entry_rcu(), but the
iterator does not currently pass the OVS lockdep condition used
elsewhere for RCU-protected OVS objects.

Pass lockdep_ovsl_is_held() to the iterator. This matches the function's
existing caller contract and lets CONFIG_PROVE_RCU_LIST distinguish the
ovs_mutex-protected update path from the RCU read-side ct_limit_get()
path.

This was found by our static analysis tool and then manually reviewed
against the current tree. In the reviewed CONFIG_PROVE_RCU_LIST triage
run, the writer-side ct limit update produced the expected "RCU-list
traversed in non-reader section!!" warning while ovs_mutex was held,
with the stack matching ct_limit_set() and ovs_ct_limit_set_zone_limit().
The change is limited to documenting the existing protection contract.

This is a lockdep annotation cleanup. It does not change the conntrack
limit list update or release behavior.

Subject: [PATCH 4748/5214] net: enetc: fix potential divide-by-zero when
 num_vsi is zero

For i.MX94 series, all the standalone ENETCs do not support SR-IOV, so
pf->caps.num_vsi is zero. This leads to a divide-by-zero in
enetc4_default_rings_allocation() when distributing rings among PF and
VFs.

Division by zero is undefined behavior in C. On ARM64, the UDIV/SDIV
instructions silently return zero rather than raising an exception, so
the issue does not cause a visible crash. However, relying on this
behavior is incorrect and poses a cross-platform compatibility risk.

Add an explicit check for num_vsi == 0 and return early after the PF's
rings have been configured.

Subject: [PATCH 4749/5214] net: ethernet: qualcomm: ppe: Demote from supported
 and fix maintainer addresses

Emails to the maintainer of Qualcomm PPE Ethernet driver (Luo Jie
<quic_luoj@quicinc.com>) bounce permanently (full mailbox), because the
"quicinc.com" addresses were deprecated for public work.  All Qualcomm
contributors are aware of that and were asked to fix their addresses.

Driver is not supported - in terms of how netdev understands supported
commitment - if maintainer does not care to receive the patches for its
code, so demote it to "maintained" to reflect true status.

Fix all occurences of Luo Jie email address to preferred and working
domain.

Subject: [PATCH 4750/5214] octeontx2-af: Free BPID bitmap on setup failure

nix_setup_bpids() allocates bp->bpids with rvu_alloc_bitmap(), which uses
a plain kcalloc(). If any of the following devm_kcalloc() allocations for
the BPID mapping arrays fails, the function returns without freeing the
bitmap. Free the BPID bitmap before returning from those error paths.

Subject: [PATCH 4751/5214] tipc: fix UAF in cleanup_bearer() due to premature
 dst_cache_destroy()

TIPC UDP media bearer teardown calls dst_cache_destroy() on its
replicast caches before calling synchronize_net() to wait for
concurrent RCU readers (transmitters) to finish:

static void cleanup_bearer(struct work_struct *work)
{
...
	list_for_each_entry_safe(rcast, tmp, &ub->rcast.list, list) {
		dst_cache_destroy(&rcast->dst_cache);
		list_del_rcu(&rcast->list);
		kfree_rcu(rcast, rcu);
	}
...
	dst_cache_destroy(&ub->rcast.dst_cache);
	udp_tunnel_sock_release(ub->sk);
	synchronize_net();
...
}

This is highly buggy because dst_cache_destroy() immediately frees the
per-CPU cache memory (free_percpu()) and releases the cached dst
entries without any synchronization.

If a concurrent transmitter (e.g., tipc_udp_xmit()) is running on another
CPU under RCU protection, it can call dst_cache_get() concurrently,
leading to:
1. Use-After-Free on the per-CPU cache pointer itself (crash).
2. "rcuref - imbalanced put()" warning if it attempts to release a
   dst that was concurrently released by dst_cache_destroy().

Furthermore, calling kfree(ub) immediately after synchronize_net() without
closing the socket first (or waiting after closing it) leaves a window
where a concurrent receiver (tipc_udp_recv()) could start after
synchronize_net(), access ub, and suffer a UAF when kfree(ub) runs.

To fix this, we must defer dst_cache_destroy() and kfree(ub) until after
we have ensured that no more readers can see the bearer/socket and all
existing readers have finished:

1. Defer rcast entry destruction (both dst_cache_destroy() and kfree())
   to an RCU callback using call_rcu_hurry().
   Using call_rcu_hurry() ensures the dst entries are released quickly.

2. Release the bearer socket using udp_tunnel_sock_release() (stops
   new receive readers).

3. Call synchronize_net() to wait for all outstanding RCU readers
   (both transmit and receive) to finish.

4. Now that it is safe, call dst_cache_destroy() on the main bearer
   cache, and free ub.

Note: 3) and 4) can be changed later in net-next to also use
call_rcu_hurry() and get rid of the synchronize_net() latency.

Subject: [PATCH 4752/5214] tipc: avoid busy looping in tipc_exit_net()

Blamed commit introduced a busy-wait loop in tipc_exit_net()
to wait for pending UDP bearer cleanup works to complete:

       while (atomic_read(&tn->wq_count))
               cond_resched();

This loop can busy-wait for a long time if cond_resched() is a NOP. This
typically happens if the netns exit is executed by a high priority task,
or under kernels configured without preemption (CONFIG_PREEMPT_NONE). In
such cases, it wastes CPU cycles and can lead to soft lockups.

Fix this by replacing the busy loop with wait_var_event(), allowing the
thread to sleep properly until the work queue count reaches zero.

Accordingly, update cleanup_bearer() to use atomic_dec_and_test() and
wake_up_var() to wake up the waiter when the count drops to zero.

This uses the global wait queue hash table, avoiding the need to bloat
struct tipc_net with a wait_queue_head_t. The atomic_dec_and_test()
provides the necessary memory barrier to ensure the wakeup is not missed.

Subject: [PATCH 4754/5214] selftests: tls: size splice_short pipe by page size

splice_short grows its pipe with (MAX_FRAGS + 1) * 0x1000 so it can
queue one short vmsplice() buffer for each fragment before draining the
pipe. That assumes 4K pipe buffers.

On 64K-page kernels the request is rounded to 262144 bytes, which
provides only four pipe buffers. The fifth one-byte vmsplice() blocks in
pipe_wait_writable and the test times out before it reaches the TLS path.

Request enough bytes for the same number of pipe buffers using the
runtime page size, and assert that the kernel granted at least that much.
If an unprivileged run cannot raise the pipe above the system
pipe-max-size limit, skip the test because it cannot exercise the
intended path.

during early driver load.

After this commit, the IRQ allocation for MANA was done in two phases.
HWC IRQ allocated earlier and then, queue IRQs dynamically added at a
later point. By this time, the IRQ weights on vCPUs can become imbalanced
and if IRQ count is greater than the vCPU count the topology aware IRQ
distribution logic in MANA can cause multiple MANA IRQs to land on the
same vCPUs, while other sibling vCPUs have none (case 1).

On SMP enabled, low-vCPU systems, this becomes a bigger problem as the
softIRQ handling overhead of two IRQs on the same vCPUs becomes much more
than their overheads if they were spread across sibling vCPUs.

In such cases when many parallel TCP connections are tested, the
throughput drops significantly.

Fix the affinity assignment logic, in cases where the IRQ count is greater
than the vCPU count and when IRQs are added dynamically, by utilizing all
the vCPUs irrespective of their NUMA/core bindings (case 2).

The results of setting the affinity and hint to NULL were also studied,
and we observed that, with this logic if there are pre-existing IRQs
allocated on the VM (apart from MANA), during MANA IRQs allocation, it
leads to clustering of the MANA queue IRQs again (case 3).

Subject: [PATCH 4756/5214] net: hns3: unify copper port ksettings
 configuration path

Refactor hns3_set_link_ksettings() and hclge_set_phy_link_ksettings()
to unify the configuration path for copper ports.

Previously, netdevs with a native kernel phy attached bypassed the main
MAC parameter caching logic and returned early via
phy_ethtool_ksettings_set(). This prevented the driver from updating
hdev->hw.mac.req_xxx variables for kernel PHY setups, leaving them
out-of-sync during reset recovery.

Clean this up by routing all copper port configurations through
ops->set_phy_link_ksettings(), and perform driver-level or kernel-level
PHY arbitration inside hclge_set_phy_link_ksettings() via
hnae3_dev_phy_imp_supported(). This ensures that the user's intended link
profiles (req_speed, req_duplex, req_autoneg) are uniformly recorded
across all copper and fiber deployment topologies, laying the groundwork
for stable reset recovery.

For copper ports where neither IMP firmware nor a kernel PHY is available
(e.g. PHY_INEXISTENT), hclge_set_phy_link_ksettings() returns -ENODEV.
In hns3_set_link_ksettings(), this is caught so the configuration falls
through to the existing MAC-level path (check_ksettings_param ->
cfg_mac_speed_dup_h), preserving compatibility with PHY-less copper
deployments.

Subject: [PATCH 4757/5214] net: hns3: refactor MAC autoneg and speed
 configuration

Extract the MAC autoneg and speed/duplex/lane configuration logic out
of hclge_mac_init() and encapsulate it into a new dedicated helper
function hclge_set_autoneg_speed_dup().

In the init path (hclge_init_ae_dev), this helper is now called after
hclge_update_port_info() so that firmware-reported autoneg values are
already populated before applying the link configuration.

Introduce a separate req_lane_num field in struct hclge_mac to isolate
the user-requested lane count from mac.lane_num, which firmware may
overwrite via hclge_get_sfp_info() with stale values from a prior link
lifecycle (e.g., lane_num=4 from 100G). During probe, req_lane_num is
initialized to 0, which instructs firmware to auto-select the correct
lane count for the current speed, rather than reusing the firmware-
reported mac.lane_num that may be inconsistent with the target speed.
This prevents probe failures from mismatched (speed, lane_num) pairs.

In the reset path (hclge_reset_ae_dev), it runs immediately after
hclge_mac_init(), using the previously cached req_* values to restore
the link without re-querying firmware.

Subject: [PATCH 4758/5214] net: hns3: fix permanent link down deadlock after
 reset

Fix a critical race condition deadlock where the network interface
remains permanently Link Down after a hardware reset under specific
ethtool sequences.

This issue exclusively manifests in firmware-controlled PHY topologies
where the driver relies on the IMP firmware to arbitrate link parameters.
Standard devices driven by the kernel's native PHY_LIB are unaffected.

The deadlock occurs via the following path:
1. User disables autoneg and forces an unmatched speed, forcing link
   down: `ethtool -s ethx autoneg off speed 10 duplex full`
2. User re-enables autoneg: `ethtool -s ethx autoneg on`. The netdev
   stack passes cmd->base.speed as SPEED_UNKNOWN (0xffffffff).
3. Driver saves req_autoneg=1, but before the interface can link up,
   a hardware reset is triggered.
4. During reset recovery, MAC init reads the un-synchronized runtime
   state mac.autoneg (which is still 0/OFF), misinterprets it as
   forced mode, and pushes the cached SPEED_UNKNOWN into the hardware
   registers, causing the MAC firmware state machine to freeze.
   Meanwhile, PHY init reads req_autoneg=1 and enables PHY autoneg.

Since the MAC is frozen with 0xffffffff and PHY is running autoneg,
they mismatch permanently.

Fix this by:
1. Intercepting SPEED_UNKNOWN/DUPLEX_UNKNOWN in
   hclge_set_phy_link_ksettings() and hclge_cfg_mac_speed_dup_h() to
   prevent it from corrupting the driver's cached valid configuration.
2. Save req_autoneg in hclge_set_autoneg().
3. Aligning the state judgment in hclge_set_autoneg_speed_dup() to use
   req_autoneg instead of the un-synchronized runtime mac.autoneg,
   ensuring both MAC and PHY consistently enter the autoneg branch to
   eliminate configuration discrepancies during reset recovery.

Subject: [PATCH 4759/5214] net: hns3: differentiate autoneg default values
 between copper and fiber

Fix a link loss issue during driver initialization on optical ports
connected to forced-mode (non-autoneg) remote switches.

Previously, during driver probe or initialization, hclge_configure()
blindly hardcoded hdev->hw.mac.req_autoneg to AUTONEG_ENABLE for all
media types. While this is necessary for copper (BASE-T) ports to
establish a link, many high-speed optical (fiber) ports in data
centers are connected to switches running in forced mode (fixed speed,
autoneg disabled). Forcing autoneg on these optical ports during
initialization causes a permanent link failure since the remote end
refuses to respond to autoneg pulses.

Fix this by implementing media-type differentiated initialization in
hclge_init_ae_dev(). Copper ports continue to default to
AUTONEG_ENABLE, while optical ports strictly inherit the preset
autoneg status pre-configured by the firmware (hdev->hw.mac.autoneg),
preserving native compatibility with forced-mode network environments.

Subject: [PATCH 4760/5214] fbdev: fbcon: fix out-of-bounds read in err_out of
 fbcon_do_set_font()

When fbcon_do_set_font() fails (e.g., due to a memory allocation failure
inside vc_resize() under heavy memory pressure), it jumps to the `err_out`
label to roll back the console state. However, the current rollback logic
forgets to restore the `hi_font` state, leading to a severe state machine
corruption.

Earlier in the function, `set_vc_hi_font()` might be called to change
`vc->vc_hi_font_mask` and mutate the screen buffer. If `vc_resize()`
subsequently fails, the `err_out` path restores `vc_font.charcount`
but entirely skips rolling back the `vc_hi_font_mask` and the screen
buffer.

This mismatch leaves the terminal in a desynchronized state. Because
`vc_hi_font_mask` remains set, the VT subsystem will still accept
character indices greater than 255 from userspace and write them to the
screen buffer. Subsequent rendering calls (e.g., `fbcon_putcs()`) will
then use these inflated indices to access the reverted, 256-character
font array, leading to a deterministic out-of-bounds read and potential
kernel memory disclosure.

Fix this by adding the missing rollback logic for the `hi_font` mask
and screen buffer in the error path.

Subject: [PATCH 4763/5214] spi: core: Abort active target transfer on
 controller suspend

When an SPI controller operating in target mode has a transfer in
progress at the time of system suspend, the suspend path proceeds
without aborting the ongoing transfer. This can leave the hardware in
an inconsistent state, potentially causing the system to hang or fail
to resume cleanly.

Fix this by invoking the controller's target_abort callback from
spi_controller_suspend() when the controller is in target mode and the
callback is registered. This ensures any active target transfer is
cleanly terminated before the controller is suspended.

Subject: [PATCH 4764/5214] rxrpc: Fix ACKALL packet handling

rxrpc_input_ackall() accepts ACKALL packets without checking whether the
call is in a state that can legitimately have outstanding transmit buffers.
A forged ACKALL can therefore reach a new service call in
RXRPC_CALL_SERVER_RECV_REQUEST before any reply packets have been queued.

In that state call->tx_top is zero and call->tx_queue is NULL, so
rxrpc_rotate_tx_window() dereferences a NULL txqueue and triggers a
null-pointer dereference.

Fix the handling of ACKALL packets by the following means:

 (1) Add two new call states: RXRPC_CALL_CLIENT_PRE_SEND which indicates
     that the client call is connected, but nothing has been transmitted as
     yet; and RXRPC_CALL_CLIENT_AWAIT_ACK, which indicates that everything
     has been transmitted at least once, but we're now waiting for the
     stuff remaining in the Tx buffer to be ACK'd (retransmissions may
     still happen).

     The RXRPC_CALL_CLIENT_PRE_SEND state is set when the call is assigned
     a channel and transitions to RXRPC_CALL_CLIENT_SEND_REQUEST when the
     first packet is transmitted.

     RXRPC_CALL_CLIENT_AWAIT_REPLY is then narrowed in scope to indicate
     that all Tx packets have been ACK'd and we're now waiting for the
     reply to be received.

 (2) As per Wyatt Feng's original patch[1], the ACKALL handler then checks
     that the call state is one in which there might be stuff in the Tx
     buffer to ACK, but now this includes AWAIT_ACK rather than
     AWAIT_REPLY.  ACKALL packets are ignored if received in the wrong
     state.

     Note that unlike Wyatt Feng's patch, it's no longer necessary to check
     to see if the Tx buffer exists as this the state set now covers this.

 (3) Make the ACKALL handler use call->tx_transmitted rather than
     call->tx_top as the former is explicitly the highest packet seq number
     transmitted, whereas the latter has a looser definition.

Thanks to Jeffrey Altman for a description of the history of the ACKALL
packet[1].

Subject: [PATCH 4767/5214] afs: Fix further netns teardown to cancel the
 preallocation charger

When an afs network namespace is torn down, it cancels and waits for the
work item that keeps the preallocated rxrpc call/conn/peer queue charged
before disabling incoming (i.e. listen 0), but there's a small window in
which it can be requeued by an incoming call wending through the I/O
thread.

Fix this by cancelling the charger work item again after reducing the
listen backlog to zero.

Subject: [PATCH 4769/5214] rxrpc: Fix the reception of a reply packet before
 data transmission

Fix rxrpc_receiving_reply() to handle the reception of an apparent reply
DATA packet before rxrpc has had a chance to send any request DATA packets
on a client call by checking to see if the call has been exposed yet by
sending the first packet.

Without this, rxrpc_rotate_tx_window() might oops.

Also fix rxrpc_rotate_tx_window() to handle the Tx queue being empty by
changing the do...while loop into a while loop, just in case a call is
abnormally terminated by an early reply before the last request packet is
transmitted.

Subject: [PATCH 4772/5214] rxrpc: Fix socket notification race

There's a race between rxrpc_recvmsg() and rxrpc_notify_socket(), whereby
the latter's attempt to avoid disabling interrupts and taking the socket's
recvmsg_lock if the call is already queued may happen simultaneously with
the former's discarding of a call that has nothing queued.

Fix this by removing the shortcut.  Note that this only affects userspace's
use of AF_RXRPC; the AFS filesystem driver doesn't use the socket queue.

Subject: [PATCH 4775/5214] net: ethtool: keep rtnl_lock for ops using
 ethtool_op_get_link()

Breno reports following splats on mlx5:

  RTNL: assertion failed at net/core/dev.c (2241)
  WARNING: net/core/dev.c:2241 at netif_state_change+0xed/0x130, CPU#5: ethtool/1335

Looks like I missed ethtool_op_get_link() trying to sync linkwatch,
which needs rtnl_lock. Not all drivers do this - bnxt doesn't,
it just returns the link state, so add an opt-in bit.

Subject: [PATCH 4776/5214] net: turn the rx_mode work into a generic
 netdev_work facility

The rx_mode update runs from a workqueue: drivers have their
ndo_set_rx_mode_async() callback executed by a single global
work item under RTNL and ops lock. This is a useful pattern.

Support multiple "events" that need to be serviced and make RX_MODE
sync the first one. Call the events "core" because later on
we will let drivers define and schedule their own.

Subject: [PATCH 4777/5214] net: add the driver-facing netdev_work scheduling
 API

With an extra event mask we can easily extend the netdev work
to also service driver-defined events. For advanced drivers
this is probably not a perfect match, but it makes running
deferred work easier in simple cases.

Expose the netdev_work facility to drivers. Add helpers
to schedule work and a dedicated ndo to perform the driver-
-scheduled actions.

Subject: [PATCH 4778/5214] vlan: defer real device state propagation to
 netdev_work

vlan_device_event() generates nested UP/DOWN, MTU and feature
change events. It executes an event for the VLAN device directly
from the notifier - while the locks of the lower device are held.

This causes deadlocks, for example:

  bond    (3) bond_update_speed_duplex(vlan)
    |           ^                v
  vlan    (2) UP(vlan)    (4) vlan_ethtool_get_link_ksettings()
    |           ^                v
  dummy   (1) UP(dummy)   (5) __ethtool_get_link_ksettings()

The dummy device is ops locked, vlan creates a nested event (2),
then bond wants to ask vlan for link state (3). bond uses the
"I'm already holding the instance lock" flavor of API. But in
this case the lock held refers to vlan itself. We hit vlan's
link settings trampoline (4) and call __ethtool_get_link_ksettings()
which tries to lock dummy. Deadlock. There's no clean way for us
to tell the vlan_ethtool_get_link_ksettings() that the caller
is already in lower device's critical section.

Defer the propagation to the per-netdev work facility instead:
the notifier only schedules netdev_work_sched(vlandev, VLAN_WORK_*),
and ndo_work (vlan_dev_work) applies the change later. Hopefully
nobody expects the VLAN state changes to be instantaneous.

If someone does expect the changes to be instantaneous we will
have to do the same thing Stan did for rx_mode and "strategically"
place sync calls, to make sure such delayed works are executed
after we drop the ops lock but before we drop rtnl_lock.

Stan suggests that if we need that down the line we may
consider reshaping the mechanism into "async notifications".
AFAICT only vlan does this sort of netdev open chaining,
so as a first try I think that sticking the complexity into
the vlan code makes sense.

One corner case is that we need to cancel the event if user
explicitly changes the state before work could run. Consider
the following operations with vlan0 on top of dummy0:

  ip link set dev dummy0 up    # queues work to up vlan0
  ip link set dev vlan0 down   # user explicitly downs the vlan
  ndo_work                     # acts on the stale event

Subject: [PATCH 4779/5214] selftests: bonding: add a test for VLAN propagation
 over a bonded real device

Add a regression test for the VLAN notifier handling that the netdev_work
deferral fixed.

A VLAN's real device propagates its UP/DOWN, MTU and feature changes onto
the VLANs stacked on top of it. This used to be done synchronously from the
real device's notifier and deadlocked when the real device was brought up
while enslaved to a bond (instance lock held across NETDEV_UP) and the VLAN
on top was itself a bond member: the synchronous propagation re-entered the
stack and took the same instance lock again.

The test covers both halves:
 - that the deferred UP/DOWN, MTU and feature propagation actually lands on
   the VLAN (link state and MTU use an ops-locked dummy, i.e. the deferral
   path; features use veth, which exports vlan_features to inherit), and
 - that the deadlock-prone topology - a VLAN on a dummy, with the VLAN and
   the dummy each enslaved to a different bond - can be built without
   hanging.

Subject: [PATCH 4780/5214] riscv: Raise default NR_CPUS for 64BIT to 256

SpacemiT has already produced a 80-core RVA23 RISC-V server [1], and
going further back, the dual-socket SG2042-based Sophgo Pisces has 128
cores (although that had some issues achieving mainline support).
Therefore, an NR_CPUS of 64 is not enough.

Raise default NR_CPUS to 256 for 64BIT (when !RISCV_SBI_V01, since very
old firmware can't support more than 64 cores). The number was picked as
a power of two that is at least double the known max. I believe this
should be the right balance between not wasting too much memory and not
having to touch this too often.

Ubuntu has already been shipping NR_CPUS=512 for riscv64. We have also
been testing NR_CPUS=256 internally at ISCAS and found negligible
performance impact and no ill effects.

Subject: [PATCH 4786/5214] scripts/sorttable: Handle RISC-V patchable ftrace
 entries

RISC-V uses -fpatchable-function-entry=8,4 when the compressed ISA is
enabled and -fpatchable-function-entry=4,2 otherwise. In both cases, the
patchable NOP area starts 8 bytes before the function symbol address.
The __mcount_loc entries therefore point at the patchable NOP area
associated with a function, while nm reports the function symbol at the
entry address used for the function range check.

After RISC-V selected HAVE_BUILDTIME_MCOUNT_SORT, sorttable started
applying that range check at build time. Without allowing entries just
before the reported function address, the mcount sorter treats valid
RISC-V ftrace callsites as invalid weak-function entries and writes
them back as zero. The resulting kernel boots with no ftrace entries,
breaking dynamic ftrace and users such as livepatch.

The failure is silent during the final link because zeroing weak-function
entries is an expected sorttable operation. At boot, those zero entries
are skipped by ftrace_process_locs(), so the only obvious symptom is that
the vmlinux ftrace table has lost valid callsites and ftrace users cannot
attach to them.

CONFIG_FTRACE_SORT_STARTUP_TEST also reports the table as sorted in this
state: it only checks that the __mcount_loc entries are in ascending
order, which a fully zeroed table trivially satisfies. The original
commit relied on this check and did not see the regression.

On an affected RISC-V QEMU boot with both CONFIG_FTRACE_SORT_STARTUP_TEST
and CONFIG_FTRACE_STARTUP_TEST enabled, the sort check still passes
while ftrace reports zero usable entries and the early selftests fail:

  [    0.000000] ftrace section at ffffffff8101da98 sorted properly
  [    0.000000] ftrace: allocating 0 entries in 128 pages
  [    0.054999] Testing tracer function: .. no entries found ..FAILED!
  [    0.172407] tracer: function failed selftest, disabling
  [    0.178186] Failed to init function_graph tracer, init returned -19

Handle RISC-V like arm64 for the function-range check and allow
patchable entries up to 8 bytes before the function address.

With this fix, a RISC-V QEMU smoke boot with ftrace startup tests shows
the vmlinux ftrace table is populated and dynamic ftrace still works:

  [    0.000000] ftrace: allocating 46749 entries in 184 pages
  [    0.051115] Testing tracer function: PASSED
  [    1.283782] Testing dynamic ftrace: PASSED
  [    6.275456] Testing tracer function_graph: PASSED

Subject: [PATCH 4787/5214] riscv: Fix 32-bit call_on_irq_stack() frame pointer
 ABI

call_on_irq_stack() uses struct member offsets to set up its link in the
frame record list. On riscv32, struct stackframe is the wrong size to
maintain stack pointer alignment, so STACKFRAME_SIZE_ON_STACK includes
padding. However, the ABI requires the frame record to be placed
immediately below the address stored in s0, so the padding must come
before the struct members.

Fix the layout by making STACKFRAME_FP and STACKFRAME_RA the negative
offsets from s0, instead of the positive offsets from sp.

Subject: [PATCH 4788/5214] selftests/bpf: don't modify the skb in the
 strparser parser prog

sockmap_parse_prog.c is attached as an SK_SKB stream parser and modifies
the skb: it calls bpf_skb_pull_data() and writes a byte into the packet.
A stream parser runs on strparser's message head and must not modify it.
A resize frees the frag_list segments strparser still tracks, leading to
a use-after-free.

Make the parser read-only. It only needs to return the message length,
which keeps it attaching once packet-modifying parsers are rejected.

Subject: [PATCH 4789/5214] bpf, sockmap: reject a packet-modifying SK_SKB
 stream parser

sk_psock_strp_parse() runs the BPF_PROG_TYPE_SK_SKB stream-parser program
to find the length of the next message. strparser assembles a message out
of several received skbs by chaining them onto the head's frag_list and
recording where to append the next one in strp->skb_nextp:

	*strp->skb_nextp = skb;
	strp->skb_nextp = &skb->next;

and then calls the parser on the head:

	len = (*strp->cb.parse_msg)(strp, head);

The parser is only meant to inspect the skb, but the program may call
bpf_skb_change_tail() -- or the sibling bpf_skb_pull_data(),
bpf_skb_change_head(), bpf_skb_adjust_room(), all allowed for SK_SKB.
Once the head carries a frag_list these go

	... -> skb_ensure_writable -> pskb_may_pull -> __pskb_pull_tail

and __pskb_pull_tail() frees the frag_list skbs that strparser still
tracks through skb_nextp:

	while ((list = skb_shinfo(skb)->frag_list) != insp) {
		skb_shinfo(skb)->frag_list = list->next;
		consume_skb(list);
	}

strp->skb_nextp now points into a freed sk_buff. The next segment of
the same message arrives in __strp_recv(), which links it with
*strp->skb_nextp = skb, an 8-byte write into the freed skb. The free
and the write happen in different __strp_recv() calls, so the message
has to span at least three segments before it triggers.

The same resize also leaves the head's length inconsistent with its
frags, so a later __pskb_pull_tail() can instead hit the
BUG_ON(skb_copy_bits(...)) in net/core/skbuff.c.

A stream parser is only meant to measure the next message, not to modify
the packet. Reject a parser whose program can change packet data
(prog->aux->changes_pkt_data) at attach time. The check is shared by
sock_map_prog_update() and sock_map_link_update_prog(), which between them
cover prog attach, link create and link update. Verdict programs are
unaffected and may still modify the skb.

Subject: [PATCH 4791/5214] Input: synaptics-rmi4 - bound the F3A keymap to the
 GPIO count

rmi_f3a_initialize() takes the GPIO count from the device query register
(f3a->gpio_count = buf & RMI_F3A_GPIO_COUNT, range 0..127).
rmi_f3a_map_gpios() then allocates gpio_key_map with
min(gpio_count, TRACKSTICK_RANGE_END) == at most 6 entries, but
rmi_f3a_attention() iterates the full gpio_count and dereferences
gpio_key_map[i], and input->keycodemax is set to the full gpio_count
while input->keycode points at the 6-entry allocation.

A device that reports gpio_count > 6 therefore causes an out-of-bounds
read of gpio_key_map[] on every attention interrupt, and out-of-bounds
accesses through the input core's default keymap ioctls: EVIOCGKEYCODE
reads past the buffer (leaking adjacent slab memory to user space) and
EVIOCSKEYCODE writes a caller-controlled value past it, for any process
able to open the evdev node, since input_default_getkeycode() and
input_default_setkeycode() only bound the index against keycodemax.

Size the keymap for the full gpio_count. The mapping loop is unchanged:
it still assigns only the first min(gpio_count, TRACKSTICK_RANGE_END)
entries; the remaining slots stay KEY_RESERVED (devm_kcalloc zero-fills)
and are skipped when reporting.

Subject: [PATCH 4793/5214] bpf: Reject offset refcount acquire arguments

bpf_refcount_acquire() increments the refcount at the caller-supplied
pointer plus the refcount field offset, then returns the caller-supplied
pointer unchanged.

The verifier records the return value as a base pointer to the refcounted
object.

bpf_list_pop_front() and bpf_rbtree_remove() can return embedded
graph-node pointers as PTR_TO_BTF_ID | MEM_ALLOC with a fixed offset equal
to the node field offset. Passing such a pointer directly to
bpf_refcount_acquire() currently passes the refcounted-kptr type check.

That makes the runtime operation start from base + node_off while the
verifier models the returned pointer as the object base.

Require refcount-acquire arguments to have zero fixed offset by carrying
the requirement through check_func_arg_reg_off() to __check_ptr_off_reg().
Programs can still acquire a refcount from a graph-node-derived pointer
after normalizing it with container_of().

Add regression coverage for bpf_refcount_acquire() on graph-node-derived

The rejected case passes a popped list node pointer directly to
bpf_refcount_acquire(), which must fail because the pointer carries a

Subject: [PATCH 4795/5214] bpf: Mask pseudo pointer values in verifier logs

print_bpf_insn() masks ldimm64 immediates for pointer-bearing pseudo
sources when pointer leaks are not allowed, but the mask only covers
BPF_PSEUDO_MAP_FD and BPF_PSEUDO_MAP_VALUE.

BPF_PSEUDO_MAP_IDX, BPF_PSEUDO_MAP_IDX_VALUE, and BPF_PSEUDO_BTF_ID can
also be resolved to kernel pointer values before the verifier log prints
the instruction. Include them in the existing pointer classification so
the log prints 0x0 instead of the rewritten address.

When bpf_check() allocates env->insn_aux_data successfully but later
fails to allocate env->succ, it jumps directly to err_free_env.

The existing vfree(env->insn_aux_data) sits before the err_free_env
label, so that direct jump bypasses it and leaks insn_aux_data.

Move vfree(env->insn_aux_data) into err_free_env so all early and late

Subject: [PATCH 4799/5214] ALSA: FCP: Fix NULL pointer dereference in
 interface lookup

A malformed USB device can provide a vendor-specific interface without
any endpoint descriptors. fcp_find_fc_interface() currently selects the
first vendor-specific interface and reads endpoint 0 from it, without
checking whether the interface actually has any endpoints.

When bNumEndpoints is zero, no endpoint array is allocated for the parsed
alternate setting, so get_endpoint(..., 0) yields an invalid endpoint
descriptor pointer. Dereferencing it through usb_endpoint_num() then
triggers a NULL pointer dereference.

Skip vendor-specific interfaces that do not have any endpoints.

Subject: [PATCH 4802/5214] fbdev: fix use-after-free in store_modes()

store_modes() replaces a framebuffer's modelist with modes from userspace.
On success it frees the old modelist with fb_destroy_modelist(). Two
fields still point into that freed list.

One pointer is fb_display[i].mode, the mode a console is using.
fbcon_new_modelist() moves these pointers to the new list. It only does so
for consoles still mapped to the framebuffer. An unmapped console is
skipped and keeps its stale pointer. Unbinding fbcon, for example, sets
con2fb_map[i] to -1 but leaves fb_display[i].mode set. An
FBIOPUT_VSCREENINFO ioctl with FB_ACTIVATE_INV_MODE later reaches
fbcon_mode_deleted(). That function reads the stale fb_display[i].mode
through fb_mode_is_equal(). The read is a use-after-free.

The other pointer is fb_info->mode, the current mode. It is set through
the mode sysfs attribute. store_modes() does not update fb_info->mode, so
it is left pointing into the freed list. show_mode(), the attribute's read
handler, dereferences the stale fb_info->mode through mode_string(). The
read is a use-after-free.

Clear both pointers before freeing the list. Commit a1f305893074 ("fbcon:
Set fb_display[i]->mode to NULL when the mode is released") added the
helper fbcon_delete_modelist(). It clears every fb_display[i].mode that
points into a given list. So far it is called only from the unregister
path. Call it from store_modes() too, and set fb_info->mode to NULL.

Subject: [PATCH 4803/5214] fbcon: fix NULL pointer dereference for a console
 without vc_data

fbcon_new_modelist() runs when a framebuffer's modelist changes. For each
console mapped to it with fb_display[i].mode set, it reads vc_cons[i].d and
passes the vc_num to fbcon_set_disp(). This assumes a console with a mode
set has a vc_data, but it can be NULL. fbcon_set_disp() sets
fb_display[i].mode before it checks vc_data, and fbcon_deinit() leaves the
mode set after the vc_data is freed. fbcon_new_modelist() then dereferences
the NULL vc_data.

Keep fb_display[i].mode set only while the console has a vc_data. Check
vc_data before setting the mode in fbcon_set_disp(), and clear the mode in
fbcon_deinit(). The existing mode check in fbcon_new_modelist() then skips
such consoles.

Subject: [PATCH 4804/5214] fbdev: Fix fb_new_modelist to prevent
 null-ptr-deref in fb_videomode_to_var

info->var, a framebuffer's current mode, is expected to have a matching
entry in info->modelist. var_to_display() relies on this and treats a
failed fb_match_mode() as "This should not happen". fb_set_var() keeps it
true by adding the mode to the list on every change, and
do_register_framebuffer() does the same at registration.

store_modes() replaces the modelist from userspace. fb_new_modelist()
validates the new modes but does not check that info->var still has a
match. It relies on fbcon_new_modelist() to re-point consoles, but that
only handles consoles mapped to the framebuffer. With fbcon unbound there
are none, so info->var is left describing a mode that is no longer in the
list.

A later console takeover runs var_to_display(), where fb_match_mode()
returns NULL and leaves fb_display[i].mode NULL. fbcon_switch() passes it
to display_to_var(), and fb_videomode_to_var() dereferences the NULL mode.

Keep the current mode in the list in fb_new_modelist(), the same way
fb_set_var() does.

Subject: [PATCH 4807/5214] net: pse-pd: scope pse_control regulator handle to
 kref lifetime

__pse_control_release() drops psec->ps via devm_regulator_put(), which
only succeeds if the devres entry added by the matching
devm_regulator_get_exclusive() is still present on pcdev->dev at the
time the pse_control's kref hits zero.

That assumption does not hold when the controller is unbound while a
pse_control still has consumers: pcdev->dev's devres list is released
LIFO, so every per-attach regulator-GET devres runs (and
regulator_put()s the underlying regulator) before
pse_controller_unregister() itself is invoked. Any later
pse_control_put() from that unbind path then reads psec->ps as a
dangling pointer inside devm_regulator_put() and WARNs at
drivers/regulator/devres.c:232 (devres_release() fails to find the
already-released match).

The pse_control's consumer handle is logically scoped to the
pse_control's refcount, not to pcdev->dev's devres lifetime. Switch to
the plain regulator_get_exclusive() / regulator_put() pair so the
regulator put in __pse_control_release() no longer depends on the
controller's devres still being present. No change to the
regulator-framework-visible refcount or lifetime of the underlying
regulator: a single get paired with a single put. The existing
devm_regulator_register() for the per-PI rails is unchanged (those ARE
correctly scoped to the controller's lifetime).

This addresses only the regulator handle. The same unbind-while-held
scenario also leaves __pse_control_release() reading psec->pcdev->pi[]
and psec->pcdev->owner after pse_controller_unregister() has freed
pcdev->pi, because the controller does not drain its outstanding
pse_control references on unregister. That wider pse_control vs
pcdev lifetime problem pre-dates this change and is addressed by the
PSE controller notifier series, which drains phydev->psec on
PSE_UNREGISTERED before pcdev->pi is freed.

Subject: [PATCH 4808/5214] seg6: validate SRH length before reading fixed
 fields

seg6_validate_srh() reads fixed SRH fields such as srh->type and
srh->hdrlen before checking that the supplied length covers the fixed
struct ipv6_sr_hdr fields.

The BPF SEG6 encap path reaches this with a BPF program-supplied pointer
and length: bpf_lwt_push_encap() and the SEG6 local BPF END_B6 and
END_B6_ENCAP actions call bpf_push_seg6_encap(), which forwards the
length to seg6_validate_srh() with no minimum-size guard.  A 2-byte SEG6
encap header can therefore make the validator read srh->type at offset 2
beyond the caller-supplied buffer.

Reject lengths shorter than the fixed SRH at the top of
seg6_validate_srh(), before any field is read.  This fixes the BPF helper
path and keeps the common validator robust.

Subject: [PATCH 4810/5214] net/sched: sch_taprio: Replace direct dequeue call
 with peek and qdisc_dequeue_peeked

When taprio's software path peeks a non-work-conserving child qdisc, the
child stashes the peeked skb in its gso_skb; taprio_dequeue_from_txq()
then takes the packet with a direct child ->dequeue() call, which ignores
that stash, orphans the peeked skb and desyncs the child's qlen/backlog.
With a qfq child this re-enters the child on an emptied list and
dereferences NULL, panicking the kernel from softirq on ordinary egress.

Take the packet through qdisc_dequeue_peeked(), as sch_red and sch_sfb
now do. The helper returns the child's stashed skb first and is a no-op
when there is none, so a work-conserving child is unaffected and the
gated path now consumes the skb whose length was charged to the budget.

multiq_dequeue() takes a packet from a band's child with a direct

the direct dequeue returns a different skb and orphans the stash,

dereferences NULL, panicking the kernel from softirq on ordinary egress.

Take the packet through qdisc_dequeue_peeked(), as sch_prio already does
and as sch_red and sch_sfb were just fixed to do. The helper is a no-op
when the child has no stash, so a work-conserving child is unaffected.

Subject: [PATCH 4813/5214] NTB: epf: Avoid pci_iounmap() with offset when
 PEER_SPAD and CONFIG share BAR

When BAR_PEER_SPAD and BAR_CONFIG share one PCI BAR, the module teardown
path ends up calling pci_iounmap() on the same iomem with some offset,
which is unnecessary and triggers a kernel warning like the following:

  Trying to vunmap() nonexistent vm area (0000000069a5ffe8)

Fix it by unmapping only when PEER_SPAD and CONFIG use difference bars.

 address calculation"

The register descriptor presence register is a packet register, which
means its bytes share a single RMI address. It does not occupy
consecutive addresses, and the register structure that follows it
is located at the next RMI address (presence_address + 1), not
(presence_address + presence_size).

Revert the incorrect address calculation introduced in commit
a98518e72439.

Subject: [PATCH 4817/5214] Input: rmi4 - tolerate short register descriptor
 structure

Some touchpads (e.g. ThinkPad T14 Gen 1) have buggy firmware that reports
a register descriptor structure size that is too small for the number of
registers it claims to have in the presence map. The remaining bytes in
the structure are 0, which with the new strict bounds checking causes the
parser to fail with -EIO, aborting the device probe.

Tolerate such short reads by dropping the remaining (unparseable or
0-size) registers from the list instead of failing the probe,
preventing the driver from trying to use them.

Subject: [PATCH 4818/5214] Input: gscps2 - advance receive buffer write index

Commit 44f920069911 ("Input: gscps2 - use guard notation when
acquiring spinlock") moved the receive loop into gscps2_read_data()
and gscps2_report_data().

While moving the code, it preserved the writes to
buffer[ps2port->append], but omitted the following producer index
update from the original loop:

	ps2port->append = (ps2port->append + 1) & BUFFER_SIZE;

As a result, append never advances. Since gscps2_report_data() only
reports bytes while act != append, the receive buffer always appears
empty and no keyboard or mouse data reaches the serio core.

Restore the omitted index update.

Subject: [PATCH 4821/5214] sctp: fix SCTP_RESET_STREAMS stream list length
 limit

SCTP_RESET_STREAMS carries a flexible array of u16 stream IDs, but the
optlen clamps treat USHRT_MAX as a byte count and then multiply
sizeof(__u16) by the fixed header size.

That caps the copied and validated option buffer at about 64 KiB, which
rejects valid requests containing more than about half of the u16 stream
ID range.

Use struct_size_t() for the maximum struct sctp_reset_streams layout
instead, so the bound matches the flexible array described by
srs_number_streams.

Subject: [PATCH 4822/5214] netpoll: fix a use-after-free on shutdown path

There is a use-after-free error on netpoll, which is clearly detected by
KASAN.

      BUG: KASAN: slab-use-after-free in _raw_spin_lock_irqsave+0x3b/0x80
      Read of size 1 at addr ... by task kworker/9:1
      Workqueue: events queue_process

      Freed by task 0:
       kfree+0x1b7/0x540
       rcu_core+0x3f8/0x7a0

The problem happens when there is a pending TX worker running in
parallel with the cleanup path.

This is what happens on netpoll shutdown path:

1) __netpoll_cleanup() is called
2) set dev->npinfo to NULL
3) call_rcu() with rcu_cleanup_netpoll_info()
  3.1) rcu_cleanup_netpoll_info() tries to cancel all workers with
       cancel_delayed_work(), but doesn't wait for the worker to finish
4) and kfree(npinfo);

Because 3.1) doesn't really cancel the work, as the comment says "we
can't call cancel_delayed_work_sync here, as we are in softirq", the TX
worker can run after 4).

Tl;DR: queue_process() is not an RCU reader, it reaches npinfo through
the work item via container_of().

Use disable_delayed_work_sync() to ensure the worker is completely
stopped and prevent any future re-arming attempts. Once npinfo is set
to NULL, senders will bail out and not queue new work. The disable flag
ensures any in-flight re-arming attempts also fail silently.

In the future, we can do the cleanup inline here without needing the
npinfo->rcu rcu_head, but that is net-next material.

Subject: [PATCH 4823/5214] sctp: add INIT verification after cookie unpacking

In SCTP handshake, the INIT chunk is initially processed by the server
and embedded into the cookie carried in INIT-ACK. The client then
returns this cookie via COOKIE-ECHO, where the server unpacks it and
reconstructs the original INIT chunk.

When cookie authentication is enabled, the cookie contents are protected
against tampering, so reusing the unpacked INIT without re-verification
is safe.

However, when cookie authentication is disabled, the reconstructed INIT
can no longer be trusted. In this case, the INIT must be explicitly
validated after unpacking to avoid processing potentially tampered data.

Add sctp_verify_init() checks after cookie unpacking in COOKIE-ECHO
processing paths (sctp_sf_do_5_1D_ce() and sctp_sf_do_5_2_4_dupcook())
when cookie_auth_enable is disabled. On failure, the new association is
freed and the packet is discarded.

Also tighten cookie validation in sctp_unpack_cookie() by verifying the
embedded chunk type is SCTP_CID_INIT before treating it as an INIT
chunk.

Finally, update sctp_verify_init() to validate parameter bounds using
the actual embedded INIT length instead of chunk->chunk_end, since the
INIT stored in COOKIE-ECHO may not span the entire chunk buffer.

Subject: [PATCH 4824/5214] net: dsa: Fix skb ownership in taggers

The tag_8021q.c tagger calls vlan_insert_tag() in dsa_8021q_xmit().
vlan_insert_tag() will consume the skb with kfree_skb() on failure
and return NULL.

When NULL is returned as error code to ->xmit() in dsa_user_xmit()
it will free the same skb again leading to a double-free.

The idea of dsa_user_xmit() and dsa_switch_rcv() dropping the skb
they held before the call to ->xmit() and ->rcv() is conceptually
wrong: the pattern elsewhere in the networking code is that consumers
drop their skb:s on failure.

Modify the ->xmit() and ->rcv() call sites to not drop the SKB if
the taggers return NULL from any of these calls. Move those drops into
the taggers so every callback error path that retains ownership consumes
the skb before returning NULL.

Keep the existing helper ownership rules: VLAN insertion helpers already
free on failure (this is the case in tag_8021q.c), while deferred
transmit paths either transfer the skb reference to worker context or
hold a worker reference with skb_get() and drop the caller's reference.

For SJA1105 meta RX, transfer the buffered stampable skb under the meta
lock and return NULL while the skb is waiting for its meta frame: the
skb is not dropped in this case.

NOTICE: Backporting patches to taggers (e.g. for stable kernels) after
this point cannot be mechanical or they will introduce double
kfree_skb().

Subject: [PATCH 4825/5214] net: airoha: dma map xmit frags with
 skb_frag_dma_map()

Map xmit skb fragments using skb_frag_dma_map() instead of
dma_map_single(skb_frag_address()). skb_frag_address() relies on
page_address() to obtain a kernel virtual address, which is not
guaranteed to work for all page types (e.g. highmem pages or
user-pinned pages from MSG_ZEROCOPY).
skb_frag_dma_map() maps the fragment directly via its struct page and
offset through dma_map_page(), avoiding the need for a kernel virtual
address entirely.
Introduce an enum airoha_dma_map_type to track how each queue entry was
mapped (single vs page), so that the matching unmap function is called
on completion and in error paths.

Fixes: 23020f049327 ("net: airoha: Introduce ethernet support for EN7581 SoC")

Subject: [PATCH 4826/5214] batman-adv: retrieve ethhdr after potential skb
 realloc on RX

pskb_may_pull() in batadv_interface_rx() could reallocate the buffer behind
the skb. Variables which were pointing to the old buffer need to be
reassigned to avoid an use-after-free.

This was done correctly for the VLAN header but missed for the ethernet
header which is later used for the TT and AP isolation handling.

Subject: [PATCH 4831/5214] batman-adv: dat: ensure accessible eth_hdr proto
 field

When batadv_get_vid() accesses the proto field of the ethernet header, it
is not checking if the data itself is accessible. The caller is responsible
for it. But in contrast to other call sites, batadv_dat_get_vid() and its
caller didn't make sure this is true. This could have caused an
out-of-bounds access.

Subject: [PATCH 4835/5214] xfs: fix incorrect use of gfp flags in
 xfs_buf_alloc_backing_mem

xfs_buf_alloc_backing_mem currently has two issues with how the GFP_
flags are set:

  - when aiming for a large folio allocation, the gfp mask is adjusted
    to try less hard, but these flags then persist for the vmalloc
    allocation, which is bogus.
  - the __GFP_NOFAIL for small allocations is also applied when readahead
    force __GFP_NORETRY which doesn't make any sense.

Fix this by only applying __GFP_NOFAIL when __GFP_NORETRY is not set,
and by reordering the code so that the large folio gfp adjustments
are performed locally just for that allocation.

Subject: [PATCH 4837/5214] xfs: fix AGFL extent count calculation in
 xrep_agfl_fill

In xrep_agfl_fill(), the call to xagb_bitmap_set() passes
'agbno - 1' as the length argument. However, xagb_bitmap_set()
expects a length (number of blocks), not an end block number.
Passing 'agbno - 1' causes used_extents to record an incorrect
range.

Fix this by calculating the correct length as 'agbno - start',
which represents the actual number of blocks filled into the AGFL.

Since the commit 91840be8f710 ("irq_work: Fix use-after-free in
irq_work_single() on PREEMPT_RT"), we observed the performance of
execve() is significantly impacted on MIPS.

While we are unsure how that commit caused the impact or how to improve
it (or even if it can be improved at all), implementing IRQ work with
self-IPI seems able to mitigate the impaction.

Perhaps this can/should be implemented for other MIPS architecture
processors as well, but we don't have the enough knowledge of them, nor
access to the hardware.  So only implement it for loongson64 here.

The Ingenic USB PHY provider is now built from phy-ingenic-usb.o under

The Ingenic defconfigs below still enable the stale `CONFIG_JZ4770_PHY`

Use `CONFIG_PHY_INGENIC_USB` instead.

Subject: [PATCH 4844/5214] ALSA: us144mkii: capture_urb_complete: redundant
 usb_anchor_urb corrupts anchor list on each resubmission

In capture_urb_complete(), usb_anchor_urb() is called on every
completion callback, but the URB is already anchored from the
initial submission in tascam_trigger_start(). Each redundant call
corrupts the anchor's doubly-linked list and inflates the URB
refcount. When usb_kill_anchored_urbs() traverses the list during
stream stop / suspend / disconnect, the corrupted list leads to
use-after-free.

Remove the redundant usb_anchor_urb() from the resubmit path.

Subject: [PATCH 4845/5214] dma-buf: dma-fence: Fix potential NULL pointer
 dereference
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The commit mentioned in the fixes tag below introduced a mechanism
through which fence producers can fully decouple from fence consumers.
This, desirable, mechanism is based on the fence's signaled-bit as the
"decoupling point".

A sophisticated interaction between RCU and atomic instructions attempts
to ensure that fence consumers can still interact with fence producers
through the dma_fence_ops (callback pointers into the producer).

This is the desired behavior: to check for decoupling, the signaled-bit
is first checked. If it's not yet signaled, RCU ensures that the ops
pointer cannot yet be NULL.

Hereby, dma_fence_signal_timestamp_locked() first sets the signaled-bit,
and then sets the ops pointer to NULL. Readers first load the ops
pointer, and then check through the signaled-bit whether the pointer can
legally be accessed.

These set and load operations could occur out of order on weakly ordered
platforms. This problem can be solved very elegantly by using the ops
pointer itself as the synchronization point. The pointer is either NULL,
or cannot become NULL while it is being used thanks to RCU.

Replace the signaled-bit check in dma_fence_timeline_name() and
dma_fence_driver_name().

Subject: [PATCH 4846/5214] dma-fence: Make dma_fence_dedup_array() robust
 against 0-count input
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

dma_fence_dedup_array() returns 1 when called with num_fences == 0:
the for-loop body never executes, j stays at 0, and the final
`return ++j` yields 1. This contradicts both the kernel-doc ("Return:
Number of unique fences remaining in the array") and the natural
expectation that 0 input gives 0 output.

The caller __dma_fence_unwrap_merge() bails out via the
`if (count == 0 || count == 1)` fast path and so is save.

But amdgpu_userq_wait_*() could reach the dedup call with a zero local
count and dereference an uninitialized fence slot in the array.

Make the contract match the documentation by returning 0 early. This
also skips an unnecessary sort() call on an empty array.

  #define BOLERO_VERSION_2_0 0x0004)

and the runtime detection:

  CDC_VA_TOP_CSR_CORE_ID_0=0x1

SC7280 has LPASS Codec Version 2.0 and not, as declared with

Create new va_macro_data with .version not set to use the runtime

Subject: [PATCH 4848/5214] hwmon: (occ) unregister sysfs devices outside occ
 lock

occ_active(false) and occ_shutdown() unregister sysfs-backed devices while
occ->lock is held.  hwmon_device_unregister() and sysfs_remove_group() can
wait for active sysfs callbacks to drain, and those callbacks can enter the
OCC update path and try to take occ->lock again.  That gives the unregister
paths the lock ordering occ->lock -> sysfs callback drain, while a callback
has the opposite edge sysfs callback -> occ->lock.

This issue was found by our static analysis tool and then manually
reviewed against the current tree.

The grounded PoC kept the real unregister and callback carrier:

  occ_shutdown()
  hwmon_device_unregister()
  occ_show_temp_1()
  occ_update_response()

Lockdep reported the circular dependency with occ_shutdown() already
holding the OCC mutex and hwmon_device_unregister() waiting on the sysfs
side:

  WARNING: possible circular locking dependency detected
  ... (sysfs_lock) ... at: hwmon_device_unregister+0x12/0x30 [vuln_msv]
  ... (&test_occ.lock) ... at: occ_shutdown.constprop.0+0xe/0x40 [vuln_msv]
  occ_update_response.isra.0+0xb/0x20 [vuln_msv]
  occ_show_temp_1.constprop.0.isra.0+0x23/0x40 [vuln_msv]
  *** DEADLOCK ***

Serialize hwmon registration and removal with a separate hwmon_lock.
Under that lock, detach occ->hwmon and update occ->active while occ->lock
is held so concurrent OCC state changes still see a stable state, then
drop occ->lock before calling hwmon_device_unregister().  Remove the
driver sysfs group before taking occ->lock in occ_shutdown(), so draining
the driver attributes cannot wait while the OCC mutex is held.  Also make
OCC update callbacks return -ENODEV after deactivation, so callbacks that
already passed sysfs active protection do not poll the hardware after
teardown has detached the hwmon device.

Subject: [PATCH 4849/5214] hwmon: (pmbus/core) honor vrm_version in
 pmbus_data2reg_vid()

pmbus_data2reg_vid() hardcoded the VR11 encoding regardless of the
vrm_version configured by the driver, while pmbus_reg2data_vid()
already switched on it. Any driver that selects a non-VR11 VID mode
and exposes a regulator (or hwmon vout setter) sent dangerously
wrong codes to PMBUS_VOUT_COMMAND -- e.g. an nvidia195mv part asked
for 200 mV got the VR11 clamp to 500 mV encoded as 0xB2, which the
chip interprets as 1080 mV.

Mirror pmbus_reg2data_vid() so writes round-trip with reads.

Subject: [PATCH 4851/5214] hwmon: (asus_atk0110) Check package count before
 accessing element

atk_ec_present() walks the management group package returned by the GGRP
ACPI method and, for each sub-package, reads its first element:

	id = &obj->package.elements[0];
	if (id->type != ACPI_TYPE_INTEGER)

without checking that the sub-package is non-empty.  ACPICA allocates the
element array with exactly package.count entries, so for a sub-package
with a zero count this reads past the allocation.

The sibling function atk_debugfs_ggrp_open() performs the same access but
skips empty packages with a package.count check first.  Add the same
check to atk_ec_present() so a malformed firmware package cannot trigger
an out-of-bounds read.

Subject: [PATCH 4852/5214] spi: dw: fix first spi transfer with dma always
 fallback to PIO

Even with proper dma engine support, the first spi transfer always
fallback to PIO, the reason is the dws->n_bytes is 0 after
initialization, so the dw_spi_can_dma() calling from __spi_map_msg()
return false, thus both tx_sg_mapped and rx_sg_mapped are false, so
for the first spi transfer, the spi_xfer_is_dma_mapped() reports false
thus fallback to PIO.

Although this brings no harm, we can simply fix this issue by
calcuating the "n_bytes" from xfer->bits_per_word.

Subject: [PATCH 4854/5214] accel/amdxdna: Fix amdxdna_client lifetime race
 during device removal

In amdxdna_remove(), all amdxdna_client structures are freed after
calling drm_dev_unplug(). However, drm_dev_unplug() does not force
existing file descriptors to be closed, so amdxdna_drm_close() may be
called after amdxdna_remove() has completed.

As a result, accessing client->pid for debug output in
amdxdna_drm_close() can lead to a use-after-free, since the access is
not protected by drm_dev_enter().

Fix this by decoupling hardware teardown from client cleanup.
amdxdna_remove() only performs hardware-related cleanup, while
per-client resources are released from amdxdna_drm_close() when the
corresponding file is closed.

Subject: [PATCH 4858/5214] vfio/pci: Latch disable_idle_d3 per device

When disable_idle_d3 was introduced in vfio-pci, it directly manipulated
the device power state with pci_set_power_state().  There were no
refcounts to maintain or balanced operations, we could unconditionally
bring the device to D0 and conditionally move it to D3hot.  Therefore
the module parameter was made writable.

Later, in commit c61302aa48f7 ("vfio/pci: Move module parameters to
vfio_pci.c"), as part of the vfio-pci-core split, the writable aspect
of the module parameter was nullified.  The parameter value could still
be changed through sysfs, but the vfio-pci driver latched the values
into vfio-pci-core globals at module init.  Loading the vfio-pci module,
or unloading and reloading, with non-default or different values could
change the globals relative to existing devices bound to vfio-pci
variant drivers.

Runtime PM was introduced in commit 7ab5e10eda02 ("vfio/pci: Move the
unused device into low power state with runtime PM"), which marks the
point where power states became refcounted.  PM get and put operations
need to be balanced, but the same module operations noted above can
change the global variables relative to those devices already bound to
vfio-pci variant drivers.  This introduces a window where PM operations
can now become unbalanced.

To resolve this with a narrow footprint for stable backports, the
disable_idle_d3 flag is latched into the vfio_pci_core_device at the
time of initialization, such that the device always operates with a
consistent value.

NB. vfio_pci_dev_set_try_reset() now unconditionally raises the
runtime PM usage count around bus reset to account for disable_idle_d3
becoming a per-device rather than global flag.  When this flag is set,
the additional get/put pair is harmless and allows continued use of the
shared vfio_pci_dev_set_pm_runtime_get() helper.

Subject: [PATCH 4859/5214] vfio/pci: Release the VGA arbiter client on
 register_device() failure

The re-order in the Fixes commit below displaced vfio_pci_vga_init() as
the last failure point of what is now vfio_pci_core_register_device()
without introducing an unwind for the VGA arbiter registration.

In current kernels this is mostly benign because vfio_pci_set_decode()
only uses pci_dev state, but the original failure path could leave a
callback with a freed vdev cookie.  The stale registration also becomes
unsafe again once the callback follows drvdata to the vfio device.

Add the required VGA unwind callout.

Subject: [PATCH 4860/5214] vfio/pci: Fix racy bitfields and tighten struct
 layout

Bitfield operations are not atomic, they use a read-modify-write
pattern, therefore we should be careful not to pack bitfields that
can be concurrently updated into the same storage unit.

This split takes a binary approach: flags that are only modified
pre/post open/close remain bitfields, flags modified from user
action, including actions that reach across to another device (ex.
reset) use dedicated storage units.

Note that the virq_disabled and bardirty flags are relocated to fill
an existing hole in the structure.

Bitfield justifications:

  has_dyn_msix: written only in vfio_pci_core_enable()
  pci_2_3: written only in vfio_pci_core_enable()
  reset_works: written only in vfio_pci_core_enable()
  extended_caps: written only in vfio_cap_len() under vfio_config_init()
  has_vga: written only in vfio_pci_core_enable()
  nointx: written only in vfio_pci_core_enable()
  needs_pm_restore: written only in vfio_pci_probe_power_state()
  disable_idle_d3: written only at .init in vfio_pci_core_init_dev()

Dedicated storage units:

  virq_disabled: written by guest INTx command writes in
                 vfio_basic_config_write() while the device is open
  bardirty: written by guest BAR writes in vfio_basic_config_write()
            while the device is open
  pm_intx_masked: written in the runtime-PM suspend path.
  pm_runtime_engaged: written by low-power feature entry/exit paths
  needs_reset: set in vfio_pci_core_disable() and cleared for devices in
               the set by vfio_pci_dev_set_try_reset()
  sriov_active: written by vfio_pci_core_sriov_configure() via sysfs
                sriov_numvfs while bound.

Subject: [PATCH 4862/5214] vfio/pci: Latch all module parameters per device

The vfio-pci module parameters of disable_idle_d3, nointxmask, and
disable_vga latch vfio-pci policy into vfio-pci-core globals each time
the vfio-pci module is initialized.  The disable_idle_d3 parameter has
already migrated to a per-device flag in order to provide consistency
for refcounted PM operations for the lifetime of the device
registration.

Pull the remaining vfio-pci module-parameter policy out of vfio-pci-core
into per-device flags set at device initialization.

This also restores the mutable aspect of the disable_idle_d3 and
nointxmask module parameters for vfio-pci, with the caveat that the
parameters are latched into the device at probe.

A notable change for variant drivers is that their devices are no longer
affected by vfio-pci module parameters and those drivers may need to
adopt similar module parameters if any devices have a hidden dependency
on vfio-pci setting non-default policy.

Subject: [PATCH 4863/5214] vfio: Remove device debugfs before releasing devres

VFIO device debugfs files created with debugfs_create_devm_seqfile()
store a devres allocated debugfs_devm_entry as inode private data.
vfio_unregister_group_dev() currently calls vfio_device_del() before
vfio_device_debugfs_exit(), but device_del() releases devres.  This can
leave debugfs entries visible with stale inode private data while
unregister waits for userspace references to drain.

Remove the per-device debugfs tree before vfio_device_del().  The debugfs
view is diagnostic only, so losing it at the start of unregister is
preferable to preserving entries whose backing storage may already have
been released.

Complete the teardown by clearing the per-device debugfs root after
removal.  This matches the global debugfs root cleanup and prevents
future users from mistaking a removed dentry for a live debugfs tree
during the remainder of unregister.

Subject: [PATCH 4864/5214] vfio/pci: Expose latched module parameter policy in
 debugfs

The nointxmask and disable_idle_d3 module parameters remain writable,
but vfio-pci now latches their values into each device at init.  Once a
device is registered, changing the module parameter only affects future
devices, leaving no direct way to confirm the effective policy for an
existing device.

Add a pci debugfs directory under the VFIO device debugfs root and
report the per-device nointxmask and disable_idle_d3 values.  These are
read-only debugfs views and use the same Y/N bool output convention as
the module parameters.

Read-only vfio-pci parameters, such as disable_vga, are not exposed here
because they cannot drift from the latched device value, therefore the
existing module parameter exposure via sysfs is sufficient.

Note that while only vfio-pci currently provides these options, the
implementation is in vfio-pci-core and therefore properly reflects the
device policy in the core, regardless of driver.

 failure

w83793_probe() creates the vrm sysfs file after creating the VID files
when VID support is present.

The normal remove path deletes vrm, but the probe error path only
removes the sensor, SDA, VID, fan, PWM and temperature files.  A later
probe failure can therefore leave vrm behind after the driver data has
been freed.

Remove vrm in the probe error path next to the VID files, matching the
normal remove path.

w83627hf_probe() creates cpu0_vid and vrm with device_create_file() when
VID information is available.

The error path and remove callback only remove the common and optional
attribute groups.  Those groups do not contain cpu0_vid or vrm, so the
files can remain after a later probe failure or after device removal
while their callbacks still expect live driver data.

Remove the standalone VID sysfs files from both the probe error path and

Subject: [PATCH 4870/5214] hwmon: adm1275: Prevent reading uninitialized stack

While adding support for the ROHM BD127X0 hot-swap controllers, sashiko
reported an error in device-name comparison, which can lead to reading
uninitialized stack memory.

Quoting Sashiko:

This is a pre-existing issue, but I noticed that just before this block in
adm1275_probe(), there might be an out-of-bounds stack read:

    ret = i2c_smbus_read_block_data(client, PMBUS_MFR_MODEL, block_buffer);
    if (ret < 0) { ... }
    for (mid = adm1275_id; mid->name[0]; mid++) {
            if (!strncasecmp(mid->name, block_buffer, strlen(mid->name)))
                    break;
    }

Since i2c_smbus_read_block_data() reads up to 32 bytes into the
uninitialized stack array block_buffer without appending a null
terminator, strncasecmp() could read past the valid bytes returned in ret.

For example, if the device returns a shorter string like "adm12", checking
it against "adm1275" up to the length of "adm1275" will continue reading
into uninitialized stack bounds.

Prevent reading uninitialized memory by zeroing the stack array.

Subject: [PATCH 4871/5214] hwmon: adm1275: Detect coefficient overflow

Sashiko detected potential coefficient overflow if large shunt resistor
is used. When going unnoticed it can cause "drastically incorrect
telemetry scaling factors" as Sashiko put it.

I am not convinced such "drastically incorrect telemetry scaling
factors" could have gone unnoticed, so I suspect such large shunt
resistors aren't really used. Well, it shouldn't hurt to detect the

Subject: [PATCH 4872/5214] bpf,fork: wipe ->bpf_storage before bailouts that
 access it

Currently, copy_process() can bail out to free_task() before p->bpf_storage
has been initialized, with this call graph (shown here for the
!CONFIG_MEMCG case):

copy_process
  dup_task_struct
    arch_dup_task_struct
      [copies the entire task_struct, including ->bpf_storage member]
  [RLIMIT_NPROC check fails]
  delayed_free_task
    free_task
      bpf_task_storage_free
        rcu_dereference(task->bpf_storage)
        bpf_local_storage_destroy

In this case, the nascent task's ->bpf_storage member that
bpf_local_storage_destroy() operates on is a plain copy of the parent's
->bpf_storage pointer, not a real initialized pointer.
This leads to badness (kernel hangs, UAF).

This is reachable as long as the process calling fork() has been inserted
into a task storage map.

Subject: [PATCH 4873/5214] hwmon: (pmbus) Fix passing events to regulator core

Sashiko reports:

Commit 754bd2b4a084 ("hwmon: (pmbus/core) Protect regulator operations with
mutex") introduced a worker to batch regulator events over time using
atomic_or(). The delayed worker then passes the combined bitmask unmodified
to regulator_notifier_call_chain().

The core regulator subsystem's regulator_handle_critical() function
evaluates the event parameter using a strict switch statement. If
multiple distinct faults occur before the worker runs (e.g.,
REGULATOR_EVENT_UNDER_VOLTAGE | REGULATOR_EVENT_OVER_CURRENT), the combined
bitmask fails to match any case. This leaves the reason as NULL and
completely bypasses the critical hw_protection_trigger().

Fix the problem by passing events bit by bit to the regulator event
handler.

Subject: [PATCH 4874/5214] hwmon: (aspeed-g6-pwm-tach) Guard fan RPM
 calculation against divide-by-zero

Sashiko reports:

In the aspeed-g6-pwm-tacho driver, the aspeed_tach_val_to_rpm() function
calculates the fan RPM using the tachometer value. However, it does not
check if the tachometer value is zero before performing the division.

If the hardware reports a tachometer value of 0 (which can happen due to
an extremely fast pulse, a stuck edge, or a hardware glitch), the
calculated tach_div evaluates to 0. The subsequent call to do_div() with
tach_div as the divisor triggers a divide-by-zero exception, leading to
a kernel panic.

Check the divisor against zero to fix the problem.

Subject: [PATCH 4876/5214] tipc: fix out-of-bounds read in broadcast Gap ACK
 blocks

A broadcast PROTOCOL/STATE_MSG can carry a Gap ACK blocks record in its
data area. tipc_get_gap_ack_blks() only verifies that the record's len
field is self-consistent with its ugack_cnt/bgack_cnt counts
(sz == struct_size(p, gacks, ugack_cnt + bgack_cnt)); it does not check
that the record actually fits in the message data area, msg_data_sz().

The unicast caller tipc_link_proto_rcv() bounds it ("if (glen > dlen)
break;"), but the broadcast caller tipc_bcast_sync_rcv() discards the
returned size, so tipc_link_advance_transmq() copies the record off the
receive skb with an attacker-controlled count:

	this_ga = kmemdup(ga, struct_size(ga, gacks, ga->bgack_cnt),
			  GFP_ATOMIC);

A TIPC neighbour that negotiated TIPC_GAP_ACK_BLOCK triggers it with one
ordinary broadcast STATE_MSG (msg_bc_ack_invalid() clear), sized so its
data area is short, carrying a Gap ACK record with len = 0x400,
bgack_cnt = 0xff and ugack_cnt = 0. len then equals
struct_size(p, gacks, 255), so the consistency check passes and ga is
non-NULL; kmemdup() reads struct_size(ga, gacks, 255) = 1024 bytes out
of the much smaller skb:

  BUG: KASAN: slab-out-of-bounds in kmemdup_noprof+0x48/0x60
  Read of size 1024 at addr ffff0000c7030d38 by task poc864/69
  Call trace:
   kmemdup_noprof+0x48/0x60
   tipc_link_advance_transmq+0x86c/0xb80
   tipc_link_bc_ack_rcv+0x19c/0x1e0
   tipc_bcast_sync_rcv+0x1c4/0x2c4
   tipc_rcv+0x85c/0x1340
   tipc_l2_rcv_msg+0xac/0x104
  The buggy address belongs to the object at ffff0000c7030d00
   which belongs to the cache skbuff_small_head of size 704
  The buggy address is located 56 bytes inside of
   allocated 704-byte region [ffff0000c7030d00, ffff0000c7030fc0)

The copied-out bytes are subsequently consumed as gap/ack values, but
the read is already out of bounds at the kmemdup() regardless of how
they are used.

The unicast STATE path drops such a message: "if (glen > dlen) break;"
skips the rest of STATE_MSG handling and the skb is freed. Make the
broadcast path drop it too. tipc_bcast_sync_rcv() now bounds the record
against msg_data_sz() and, when it does not fit, reports it back through
tipc_node_bc_sync_rcv() to tipc_rcv() so the skb is discarded rather than
processed. ga is not cleared on this path: ga == NULL already means
"legacy peer without Selective ACK", a distinct legitimate state.

Subject: [PATCH 4877/5214] net: wwan: iosm: bound device offsets in the MUX
 downlink decoder

mux_dl_adb_decode() walks a chain of aggregated datagram tables using
offsets and lengths taken from the modem. first_table_index,
next_table_index, table_length, datagram_index and datagram_length are
all device supplied le values. Only first_table_index was checked, and
only for being non zero. The decoder then formed adth = block +
adth_index and read the table header and the datagram entries with no
bound against the received skb. A modem that reports an index or a
length past the downlink buffer makes the decoder read out of bounds.

The buffer is IPC_MEM_MAX_DL_MUX_LITE_BUF_SIZE and skb->len is at most
that, so skb->len is the real limit, but none of these in band offsets
were checked against it.

The table chain is also followed with no forward progress check. The loop
takes the next table from adth->next_table_index and stops only when that
reaches zero. A modem can stage two tables that point at each other, so
the loop never ends. It runs in softirq and clones the skb on every pass.

Validate every device offset and length against skb->len before use.
The block header must fit. Each table header, on entry and after every
next_table_index, must lie inside the skb. The datagram table must fit.
Each datagram index and length must stay inside the skb. The header
padding must not exceed the datagram length so the receive length does
not wrap. Require each next_table_index to move forward so the chain
cannot cycle.

This was reproduced under KASAN as a slab out of bounds read on a normal
downlink receive once the iosm net device is up.

Subject: [PATCH 4878/5214] tcp: restore RCU grace period in
 tcp_ao_destroy_sock

Commit 51e547e8c89c ("tcp: Free TCP-AO/TCP-MD5 info/keys without RCU")
removed the call_rcu() callback from tcp_ao_destroy_sock(), arguing that
"the destruction of info/keys is delayed until the socket destructor"
and therefore "no one can discover it anymore".

That argument does not hold for the call site in tcp_connect()
(net/ipv4/tcp_output.c:4327-4332). At that point the socket is in
TCP_SYN_SENT, has already been inserted into the inet ehash by
inet_hash_connect() in tcp_v4_connect(), and is therefore very much
discoverable: any softirq running tcp_v4_rcv() on another CPU can take
the socket out of the ehash, walk into tcp_inbound_hash(), and load
tp->ao_info via implicit RCU before bh_lock_sock_nested() is taken on
the destroying CPU.

The reader path then enters __tcp_ao_do_lookup() (net/ipv4/tcp_ao.c:208)
which re-loads tp->ao_info via rcu_dereference_check(); the re-load can
still observe the (about-to-be-freed) pointer because there is no
synchronize_rcu() between rcu_assign_pointer(tp->ao_info, NULL) and
tcp_ao_info_free() in tcp_ao_destroy_sock(). The captured pointer is
then walked at line 223:

	hlist_for_each_entry_rcu(key, &ao->head, node, ...)

The writer's synchronous kfree() is free to complete between the line
218 re-fetch and the line 223 hlist iteration. The slab is reused
(or simply LIST_POISON1-stamped if not yet reused) and the iteration
walks attacker-controlled or poison memory in softirq context.

Reproducer (no debug shim, stock x86_64 v7.1-rc2 SMP+KASAN, QEMU+KVM):
an unprivileged uid=1000 process inside CLONE_NEWUSER|CLONE_NEWNET
installs TCP_MD5SIG + TCP_AO_ADD_KEY on a TCP socket, sprays forged
TCP-AO segments toward its eventual 4-tuple via raw sockets, then
calls connect(). The md5-wins reconciliation in tcp_connect() fires
tcp_ao_destroy_sock(); the softirq backlog reader on the loopback
NAPI path crashes on the freed ao->head.first walk:

  Oops: general protection fault, probably for non-canonical
    address 0xfbd59c000000002f
  KASAN: maybe wild-memory-access in range
    [0xdead000000000178-0xdead00000000017f]
  CPU: 0 UID: 1000 PID: 100 Comm: repro_userns
  RIP: 0010:__tcp_ao_do_lookup+0x107/0x1c0
  Call Trace: <IRQ>
    __tcp_ao_do_lookup+0x107/0x1c0

    tcp_inbound_hash+0x7ce/0x1240
    tcp_v4_rcv+0x1e7a/0x3e10
    ...

Restore the RCU grace period: re-add struct rcu_head to tcp_ao_info
and replace the synchronous tcp_ao_info_free() with a call_rcu()
callback. Readers that captured tp->ao_info before rcu_assign_pointer
NULLed it now see the object remain valid until rcu_read_unlock().
With the patch applied the reproducer runs cleanly for 2000 iterations
on the same kernel build.

Subject: [PATCH 4879/5214] tcp: defer md5sig_info kfree past RCU grace period
 in tcp_connect

The md5+ao reconciliation in tcp_connect() (net/ipv4/tcp_output.c)
has two symmetric branches:

	if (needs_md5) {
		tcp_ao_destroy_sock(sk, false);
	} else if (needs_ao) {
		tcp_clear_md5_list(sk);
		kfree(rcu_replace_pointer(tp->md5sig_info, NULL, ...));
	}

Both branches free a per-socket auth-info object while the socket is
in TCP_SYN_SENT and is already on the inet ehash (inserted by
inet_hash_connect() in tcp_v4_connect()). Both branches are reachable
by softirq RX-path readers that load the corresponding info pointer
via implicit RCU before bh_lock_sock_nested() is taken.

The needs_md5 branch is fixed in the prior patch by re-introducing
the call_rcu() free in tcp_ao_destroy_sock(): the equivalent per-key
loop runs inside tcp_ao_info_free_rcu(), the RCU callback, so by the
time it frees each tcp_ao_key all softirq readers that captured the
container have already completed rcu_read_unlock().

The needs_ao branch is not symmetric in the same way. The container
free can be deferred via kfree_rcu(md5sig, rcu) -- struct
tcp_md5sig_info already has the required rcu member
(include/net/tcp.h:1999-2002), and the rest of the tree already does
this in the tcp_md5sig_info_add() rollback paths
(net/ipv4/tcp_ipv4.c:1410, 1436). But the per-key teardown is done
by tcp_clear_md5_list() in process context BEFORE the container's
RCU grace period: it walks &md5sig->head and frees each
tcp_md5sig_key with bare hlist_del + kfree. A concurrent softirq
reader in __tcp_md5_do_lookup() / __tcp_md5_do_lookup_exact()
(tcp_ipv4.c:1253, 1298) walks the same list via
hlist_for_each_entry_rcu() and races with that bare kfree on the
keys themselves -- a per-key slab use-after-free of the same class
as the TCP-AO bug, on the same race window.

Fix this in two halves:

  1. Convert the bare kfree() in tcp_connect() to kfree_rcu() so the
     md5sig_info container joins the rest of the md5sig lifecycle.
     The local-variable lift is mechanical and required because
     kfree_rcu() is a macro that expects an lvalue.

  2. Make tcp_clear_md5_list() RCU-safe by replacing hlist_del +
     kfree(key) with hlist_del_rcu + kfree_rcu(key, rcu). struct
     tcp_md5sig_key already carries the rcu member
     (include/net/tcp.h:1995) and tcp_md5_do_del()
     (net/ipv4/tcp_ipv4.c:1456) already uses kfree_rcu, so this
     restores the lifecycle invariant the rest of the file follows
     rather than introducing a one-off.

The other caller of tcp_clear_md5_list() is tcp_md5_destruct_sock()
(net/ipv4/tcp.c:412), which runs from the sock destructor when the
socket is already unhashed and unreachable; the extra grace period
there is unnecessary but harmless. Making the helper unconditionally
RCU-safe is the cleaner contract.

The needs_ao branch is not reachable by the userns reproducer used
to demonstrate the AO-side splat (the repro installs both keys but
ends up in the needs_md5 branch because the connect peer matches
the MD5 key, not the AO key); however the symmetric race exists
and a maintainer touching this code should not have to think about
which branch escapes RCU and which one does not.

Subject: [PATCH 4881/5214] ipv6: fib6: fix NULL deref in fib6_walk_continue()
 on multi-batch dump

inet6_dump_fib() saves its progress in cb->args[1] as a positional
index within the current hash chain.  Between batches, a concurrent
fib6_new_table() can insert a new table at the chain head, shifting
all existing entries.  The saved index then lands on a different
table, causing fib6_dump_table() to set w->root to the wrong table
while w->node still points into the previous one.
fib6_walk_continue() dereferences w->node->parent (NULL) and panics:

  BUG: kernel NULL pointer dereference, address: 0000000000000008
  RIP: 0010:fib6_walk_continue+0x6e/0x170

Fix by storing tb->tb6_id in cb->args[1] instead of a positional
index.  On resume, skip entries until the id matches; a concurrent
head-insert can never match the saved id, so the walker always
resumes on the correct table.

Subject: [PATCH 4882/5214] netdevsim: remove ethtool debugfs files before
 freeing netdev

The ethtool debugfs files point directly into struct netdevsim, which is
allocated as net_device private data. Their containing port directory is
removed only after nsim_destroy() calls free_netdev().

An open simple-attribute file can consequently dereference the freed
private data before the directory is removed. KASAN observed this in
debugfs_u32_get() during network namespace teardown.

Track and remove the ethtool subtree before free_netdev() on both the
normal and registration-failure paths. debugfs removal drains active
file users before returning.

Subject: [PATCH 4883/5214] net/mlx5e: macsec: fix use-after-free of
 metadata_dst on RX SC delete

When an offloaded MACsec RX SC is deleted, macsec_del_rxsc_ctx() freed
the per-SC metadata_dst with metadata_dst_free(), which kfree()s the
object unconditionally and ignores the dst reference count. The RX
datapath in mlx5e_macsec_offload_handle_rx_skb() looks up the SC under
rcu_read_lock() via xa_load(), takes a reference with dst_hold() and
attaches the dst to the skb with skb_dst_set(). A reader that already
obtained the rx_sc pointer can race with the delete path and operate on
freed memory.

Fix the owner side by dropping the reference with dst_release() instead
of freeing unconditionally, and convert the RX datapath to
dst_hold_safe() so a reader racing the SC delete cannot attach a dst
whose last reference was just dropped; only attach it when a reference
was actually taken.

mlx5e_macsec_add_rxsc() also published sc_xarray_element via xa_alloc()
before rx_sc->md_dst was allocated and initialised, so a datapath reader
that looked the SC up by fs_id could observe rx_sc with md_dst still
NULL or, on weakly-ordered architectures, a non-NULL md_dst pointer
whose contents were not yet visible. NULL-check the xa_load() result and
md_dst on the datapath, and reorder add_rxsc() so the xa_alloc() publish
happens only after md_dst is fully initialised; the xarray RCU publish
then pairs with the rcu_read_lock()/xa_load() in the datapath.

Note: macsec_del_rxsc_ctx() also kfree()s rx_sc->sc_xarray_element
without an RCU grace period while the same datapath reads it under
rcu_read_lock(); that is a separate pre-existing issue left to a
follow-up patch.

Found by 0sec automated security-research tooling (https://0sec.ai).

Subject: [PATCH 4884/5214] usbnet: gl620a: fix out-of-bounds read in
 genelink_rx_fixup()

genelink_rx_fixup() splits an aggregated RX frame into its individual
packets, using a per-packet length taken from device-supplied data. That
length is only bounded by GL_MAX_PACKET_LEN (1514); it is never compared
against how many bytes were actually received.

A malicious GeneLink (GL620A) device can therefore send a short URB whose
header claims packet_count > 1 and a first packet of up to 1514 bytes.

	skb_put_data(gl_skb, packet->packet_data, size);

then copies past the end of the receive buffer and hands the adjacent slab
contents up the network stack, an out-of-bounds read that leaks kernel heap.
No privilege is required: the path runs in the usbnet RX softirq as soon as
the interface is up.

  BUG: KASAN: slab-out-of-bounds in genelink_rx_fixup (drivers/net/usb/gl620a.c:112)
  Read of size 1514 at addr ffff888011309708 by task ksoftirqd/0/14
  Call Trace:
    ...
    __asan_memcpy (mm/kasan/shadow.c:105)
    genelink_rx_fixup (include/linux/skbuff.h:2814 drivers/net/usb/gl620a.c:112)

    handle_softirqs (kernel/softirq.c:622)
    run_ksoftirqd (kernel/softirq.c:1076)
    ...

skb_pull() already verifies that the requested length fits the buffer and
returns NULL otherwise. Move it ahead of the copy and check its result, so
a packet that overruns the received data is rejected before it is read.
Well-formed frames, whose packets are fully present, are unaffected.

Subject: [PATCH 4885/5214] net: phy: sfp: free mii_bus in
 sfp_i2c_mdiobus_destroy

sfp_i2c_mdiobus_create() allocates the I2C MDIO bus with mdio_i2c_alloc(),
a plain (non-devm) allocation, and registers it. sfp_i2c_mdiobus_destroy()
only unregisters the bus and clears sfp->i2c_mii without calling
mdiobus_free(). As the only reference to the bus is then cleared, the
struct mii_bus is leaked.

This is hit whenever a copper/RollBall SFP module that instantiated an MDIO
bus is removed: sfp_sm_main() takes the global teardown path and calls
sfp_i2c_mdiobus_destroy(). sfp_cleanup(), on driver unbind, frees
sfp->i2c_mii directly, which is why the leak only triggered on module
hot-removal and not on unbind.

Free the bus in sfp_i2c_mdiobus_destroy() to match the allocation done in
sfp_i2c_mdiobus_create().

Subject: [PATCH 4886/5214] Revert "net: phy: sfp: probe for RollBall
 I2C-to-MDIO bridge in mdio-i2c"

This reverts commit 8fe125892f40 ("net: phy: sfp: probe for RollBall
I2C-to-MDIO bridge in mdio-i2c").

That commit added a RollBall bridge probe at MDIO bus creation time, in
i2c_mii_init_rollball(), to avoid a multi-minute PHY probe retry loop on
modules without a bridge (e.g. RTL8261BE). The probe runs in SFP_S_INIT,
before genuine RollBall modules have finished their firmware/bridge
initialization, so the bridge does not yet answer CMD_READ/CMD_DONE. The
probe times out, mdio_protocol is set to MDIO_I2C_NONE, and PHY detection
is then skipped for genuine RollBall modules that worked before the commit.

This was confirmed on hardware by Maxime Chevallier and Aleksander
Bajkowski: their RollBall modules no longer detect a PHY, and work again
on v7.0 (before the bridge probing was introduced). The Sashiko static
review flagged the same path.

Deferring the probe to PHY discovery time does not fix it either: at that
point a slow module may still be initializing, so the probe still returns
-ENODEV. A proper fix needs per-module init timing (a longer module_t_wait
or a per-module quirk, per SFF-8472 the host must also wait at least 300 ms
after insertion), which requires genuine RollBall hardware to develop and
validate. Revert to restore the previous, working behaviour in the meantime.

The RTL8261BE retry-loop latency that the reverted commit addressed is
handled in our downstream tree, so reverting upstream is safe on our side.

Subject: [PATCH 4888/5214] netfilter: nf_conntrack_expect: zero at allocation
 time

There are occasional LLM hints wrt. leaking uninitialized data to
userspace via ctnetlink.  Just zero at allocation time,
expectations are not frequently used these days.

Intentionally keeps _init as-is because we could theoretically
support re-init, so add the missing exp->dir there.

Subject: [PATCH 4889/5214] netfilter: nft_set_pipapo: don't leak bad clone
 into future transaction

On memory allocation failure the cloned nft_pipapo_match can enter a bad
state:
 - some fields can have their lookup tables resized while others did
   not
 - bits might have been toggled
 - scratch map can be undersized which also means m->bsize_max can be
   lower than what is required

This means that the next insertion in the same batch can trigger
out-of-bounds writes.

Furthermore, a failure in the first can result in the bad clone to
leak into the next transaction because the abort callback is never
executed in this case (the upper layer saw an error and no attempt to
allocate a transactional request was made).

Record a state for the nft_pipapo_match structure:
- NEW (pristine clone)
- MOD (modified clone with good state)
- ERR (potentially bogus content)

Then make it so that deletes and insertions fail when the clone
entered ERR state.

In case the very first insert attempt results in an error, free the
clone right away.

Subject: [PATCH 4890/5214] netfilter: ipset: fix race between dump and
 ip_set_list resize

The release path of ip_set_dump_do() and ip_set_dump_done() read
inst->ip_set_list via ip_set_ref_netlink(), a plain rcu_dereference_raw()
of the array pointer. These run from netlink_recvmsg() without the nfnl
mutex and without an RCU read-side critical section.

A concurrent ip_set_create() can grow the array: it publishes the new
array, calls synchronize_net() and then kvfree()s the old one. Since the
dump paths read the array outside any RCU reader, synchronize_net() does
not wait for them and the old array can be freed while they still index
into it, causing a use-after-free.

The dumped set itself stays pinned via set->ref_netlink, so only the
array load needs protecting. Take rcu_read_lock() around it, matching
ip_set_get_byname() and __ip_set_put_byindex().

Subject: [PATCH 4891/5214] netfilter: nf_conntrack_sip: validate skb_dst()
 before accessing it

tc ingress and openvswitch do not guarantee routing information to be
available. These subsystems use the conntrack helper infrastructure, and
the SIP helper relies on the skb_dst() to be present if
sip_external_media is set to 1 (which is disabled by default as a module
parameter).

This effectively disables the sip_external_media toggle for these
subsystems without resulting in a crash.

Subject: [PATCH 4893/5214] netfilter: nft_fib: reject fib expression on the
 netdev egress hook

A fib expression in a netdev egress base chain dereferences nft_in(pkt),
NULL on the transmit path, causing a NULL pointer dereference at eval.
nft_fib_validate() masks the hook with NF_INET_* values, but netdev hook
numbers are a separate enum that aliases them (NF_NETDEV_EGRESS ==
NF_INET_LOCAL_IN), so an egress chain passes validation and then faults.

Add nft_fib_netdev_validate() that limits each result/flag to the netdev
hook where the device it reads exists: the input-device cases (OIF,
OIFNAME, ADDRTYPE with F_IIF) to ingress, the output-device case (ADDRTYPE
with F_OIF) to egress, ADDRTYPE with no device flag to both. Also restrict
nft_fib_validate() to NFPROTO_IPV4/IPV6/INET so its NF_INET_* masks are
not applied to another family's hooks.

Fixes: 42df6e1d221d ("netfilter: Introduce egress hook")

Subject: [PATCH 4894/5214] netfilter: nfnetlink_queue: restrict writes to
 network header

nfnetlink_queue doesn't allow selective replacements of some part of the
payload, only complete replacement.
If the new data is shorter, skb is trimmed, otherwise expanded.

Add minimal validation of the new ip/ipv6 header.  Check total len
matches skb length.  Disallow ip option modifications.

IPv6 extension headers are also disabled.
IP options and exthdrs could be allowed later after validation pass or
ip option recompile.

Transport header is not checked.

Bridge modifications are rejected.  Given userspace doesn't even receive
L2 headers, use is limited and I don't think there are any users of
bridge nfnetlink_queue, let alone users that modifiy payload.

Arp isn't supported at all.

Subject: [PATCH 4895/5214] netfilter: nftables: restrict linklayer and network
 header writes

Don't permit arbitrary writes to linklayer and network header data.
Several spots in network stack trust header validation performed in
ipv4/ipv6 before PRE_ROUTING hook.

For linklayer, allow writes for netdev ingress. For other hooks, only
allow link layer writes that do not spill into network header.

For network header, check the offset/length combinations:
 - changing dscp requires store at offset 0 for checsum fixups, so
 make sure ip version + length field isn't altered.
 - ip6 dscp starts directly after the version field, so make sure it
   remains 6.

Several of these checks could already be done at rule insertion time.
Risk is that this might cause ruleset load failures for existing
rulesets. With this change such writes are silently skipped and packet
passes unchanged.

Transport and inner header bases are not checked / restricted.

Subject: [PATCH 4896/5214] netfilter: nftables: restrict checkum update offset

After previous patch, writes to network header are restricted.
However, there is another way to manipulate the l3 header: The
checksum update function.

Restrict this for network header writes, only the ipv4 header is
allowed.  This needs run-time checks because BRIDGE, INET, NETDEV
families can carry l3 headers other than IP.

checksum updates to the udp/tcp (l4) headers are not restricted.

 overflow

The data->streams[] overflow check is done after the buffer overflow has
already happened. Move the overflow check before the write.

Side note, emitting a warning splat with a backtrace might be overkill
here, but prefer not changing the behaviour other than not doing the
overrun.

The HDCP 2.2 specification requires the seq_num_v to be monotonically
increasing, and repeated seq_num_v needs to be treated as an integrity
failure. Make it so.

For the first message, seq_num_v must be zero, and is already
checked. We can only check for less-than-or-equal for the subsequent
messages, where hdcp2_encrypted is true.

Subject: [PATCH 4900/5214] gpio-f7188x: Add support for NCT6126D version B

The Nuvoton NCT6126D Super-I/O is available in two hardware revisions.
According to the manufacturer datasheet revision 2.4, version A reports
chip ID 0xD283, while version B reports chip ID 0xD284.

The driver currently only recognizes only the version A ID. Version B
only contains hardware fixes unrelated to the GPIO functionality, so it
can be supported by simply adding its chip ID without any other driver
changes.

Subject: [PATCH 4902/5214] net: airoha: fix max receive size configuration

Set the GDM maximum receive size to AIROHA_MAX_RX_SIZE unconditionally
during hardware initialization instead of updating it according to the
configured MTU. This avoids dropping incoming frames that exceed the
current MTU but could still be processed by the networking stack, which
is able to fragment the reply on the TX side (e.g. ICMP echo requests).
Move the per-port MTU configuration to the PPE egress path where it
belongs, and set the tx frame size running airoha_ppe_set_xmit_frame_size()
to dynamically track the maximum MTU across running interfaces sharing
the same PPE instance.
Fix the PPE MTU register addressing to pack two port entries per
register word and add WAN_MTU0 configuration for non-LAN GDM devices.

Subject: [PATCH 4903/5214] net: libwx: fix VMDQ mask for 1-queue mode

In wx_set_vmdq_queues(), the VMDQ mask was not set for the devices not
supporting WX_FLAG_MULTI_64_FUNC, i.e., NGBE devices. A mask of 0 causes
__ALIGN_MASK(1, ~vmdq->mask) to return 0, which incorrectly sets
q_per_pool to 0 in wx_write_qde().

Fix the VMDQ 1-queue mask to 0x7F then ensures that __ALIGN_MASK(1,
~0x7F) correctly evaluates to 1.

Subject: [PATCH 4907/5214] net: lan743x: Initialize eth_syslock spinlock
 before use

lan743x_hardware_init() calls pci11x1x_strap_get_status() during the
PCI11x1x probe sequence. That helper acquires the Ethernet subsystem
hardware lock via lan743x_hs_syslock_acquire(), which relies on
adapter->eth_syslock_spinlock to serialize access.

The spinlock is currently initialized only after the strap status is
read. With CONFIG_DEBUG_SPINLOCK enabled, taking the zeroed initialized
spinlock can trip the spinlock debug check.

Fix by initializing adapter->eth_syslock_spinlock before reading the
strap status so the probe path never attempts to lock an uninitialized
spinlock.

Subject: [PATCH 4908/5214] net: gianfar: dispose irq mappings on probe failure
 and device removal

irq_of_parse_and_map() creates irqdomain mappings that should be
balanced with irq_dispose_mapping(). The driver never called
irq_dispose_mapping(), leaking mappings on probe failure and
device removal.

Fix by adding irq_dispose_mapping() in free_gfar_dev() and
expanding its loop from priv->num_grps to MAXGROUPS so the
error path also catches partially-initialized groups. All
irqinfo pointers are pre-initialized to NULL in gfar_of_init(),
making the NULL-guarded walk in free_gfar_dev() safe for every
scenario.

gfar_parse_group() itself is left as a simple parse function
with no resource management; cleanup is centralized in the
caller's error path.

Subject: [PATCH 4909/5214] net/sched: sch_teql: Introduce slaves_lock to avoid
 race condition and UAF

The teql master->slaves singly linked list is not protected against
multiple writes. It can be mod'ed concurently from teql_master_xmit(),
teql_dequeue(), teql_init() and teql_destroy() without holding any list
lock or RCU protection.

zdi-disclosures@trendmicro.com has demonstrated that the qdisc is freed
after an RCU grace period, but teql_master_xmit() running on another
CPU can still hold a stale pointer into the list, resulting in a
slab-use-after-free:

BUG: KASAN: slab-use-after-free in teql_master_xmit+0xf0f/0x16b0
Read of size 8 at addr ffff888013fb0440 by task poc/332
Freed 512-byte region [ffff888013fb0400, ffff888013fb0600) (kmalloc-512)

The fix?
Add a per-master slaves_lock spinlock that serializes all mutations of
master->slaves and the NEXT_SLAVE() links in teql_destroy() and
teql_qdisc_init(). teql_master_xmit() also takes the same slaves_lock
around those updates.
Annotate master->slaves and the per-slave ->next pointer with __rcu and
use the appropriate RCU accessors everywhere they are touched:
rcu_assign_pointer() on the writer side (under slaves_lock),
rcu_dereference_protected() for the writer-side loads (also under
slaves_lock), rcu_dereference_bh() for the loads in teql_master_xmit() and
rtnl_dereference() for the loads in teql_master_open()/teql_master_mtu(),
which run under RTNL.
Pair this with rcu_read_lock_bh()/rcu_read_unlock_bh() around the list
traversal in teql_master_xmit(), so that readers either observe a fully
linked list or are deferred until the in-flight mutation completes. The two
early-return paths in teql_master_xmit() are updated to release the RCU-bh
read-side critical section before returning, since leaving it held would
disable BH on that CPU for good.

Subject: [PATCH 4911/5214] drm/virtio: bound EDID block reads to the response
 buffer

virtio_get_edid_block() validates the read offset only against the
device-supplied resp->size field, never against the fixed-size resp->edid
array. The EDID block index is driven by the device-supplied extension
count, so a malicious virtio-gpu backend can advertise a large size
together with a high block count and read far past the array into adjacent
kernel memory, which is then surfaced in the parsed EDID (an out-of-bounds
read / info leak).

Also reject any read whose end exceeds the size of the edid array.
Conforming EDID responses stay within the array and are unaffected.

Subject: [PATCH 4912/5214] bridge: stp: Fix a potential use-after-free when
 deleting a bridge

The three STP timers are not supposed to be armed while the bridge is
administratively down. They are synchronously deactivated when the
bridge is put administratively down and the various call sites check for
'IFF_UP' before arming them.

This check is missing from br_topology_change_detection() and it is
possible to engineer a situation in which the topology change timer is
armed while the bridge is administratively down, resulting in a
use-after-free [1] when the bridge is deleted.

Fix by adding the missing check and for good measures synchronously
shutdown the three timers when the bridge is deleted.

Subject: [PATCH 4913/5214] gpio: shared-proxy: always serialize with a
 sleeping mutex

The shared GPIO descriptor used either a mutex or a spinlock, chosen at
runtime from the underlying chip's can_sleep:

	shared_desc->can_sleep = gpiod_cansleep(shared_desc->desc);
	... if (can_sleep) mutex_lock(); else spin_lock_irqsave();

can_sleep describes only the value path (->get/->set). Under the same
lock, however, the proxy may call gpiod_set_config() and
gpiod_direction_*(), which can reach pinctrl paths that take a mutex
(e.g. gpiod_set_config() -> gpiochip_generic_config() ->
pinctrl_gpio_set_config()), independent of can_sleep. On a controller
with non-sleeping MMIO value ops the descriptor lock was a spinlock, so
the sleeping pinctrl call ran from atomic context. Reproduced on an
Amlogic A113X board with the workaround from commit 28f240683871
("pinctrl: meson: mark the GPIO controller as sleeping") reverted; the
original Khadas VIM3 report hit the same path:

	BUG: sleeping function called from invalid context
	  __mutex_lock
	  pinctrl_get_device_gpio_range
	  pinctrl_gpio_set_config
	  gpiochip_generic_config
	  gpiod_set_config
	  gpio_shared_proxy_set_config   <- voting spinlock held
	  ...
	  mmc_pwrseq_simple_probe

The spinlock existed to take the value vote from atomic context, but the
vote and the (possibly sleeping) control operations share the same state
and lock, so this scheme cannot serialize config under a mutex and still
offer atomic value access. Always serialize the shared descriptor with a
mutex instead and mark the proxy a sleeping gpiochip, driving the
underlying GPIO through the cansleep value accessors: those are valid
for both sleeping and non-sleeping chips, so value access keeps working
on fast controllers, at the cost of no longer being atomic.

With every vote edge now driven through the cansleep value setter,
gpio_shared_proxy_set_unlocked() no longer needs a per-call setter: drop
its set_func callback and call gpiod_set_value_cansleep() directly. The
shared direction_output path reaches it only once the line is already an
output, so driving the value there is equivalent to re-issuing
gpiod_direction_output(), without the redundant per-edge re-assertion of
drive config and bias.

This is observable: consumers gating on gpiod_cansleep() take their
sleeping branch on a proxied GPIO (mmc-pwrseq-emmc skips its
emergency-restart reset handler; its normal reset is unaffected), and
consumers that reject sleeping GPIOs (pwm-gpio, ps2-gpio, ...) would
fail to probe. Such atomic users do not share a pin through the proxy,
whose purpose is voting on shared reset/enable lines. The same narrowing
already applies on Amlogic since that workaround, and rockchip
addressed the identical splat per-driver in commit 7ca497be0016 ("gpio:
rockchip: Stop calling pinctrl for set_direction"); fixing the proxy
addresses the locking error once, for every controller.

The lock type was added by commit a060b8c511ab ("gpiolib: implement
low-level, shared GPIO support"); the sleeping call under it arrived with
the proxy driver.

Subject: [PATCH 4914/5214] drm/arm/malidp: use clk_bulk API in runtime PM
 resume and suspend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

malidp_runtime_pm_resume() calls clk_prepare_enable() three times
without checking the return value. If any clock fails to enable, the
driver silently proceeds with unclocked hardware, leading to undefined
behavior.

Convert both the resume and suspend paths to use the clk_bulk API:
clk_bulk_prepare_enable() in resume checks the return value and rolls
back any successfully enabled clocks on failure;
clk_bulk_disable_unprepare() in suspend keeps the two paths symmetric.

This issue was found by code review without access to Mali DP hardware.

Subject: [PATCH 4915/5214] drm/arm/komeda: fix error handling for
 clk_prepare_enable() and callers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

komeda_dev_resume() calls clk_prepare_enable() without checking the
return value. If the clock fails to enable, the function returns 0
(success) while IRQs are enabled and IOMMU is connected on potentially
unclocked hardware, causing undefined behavior on resume.

Propagate the error from clk_prepare_enable() and fix all call sites
in komeda_drv.c that previously ignored the return value of
komeda_dev_resume():

- komeda_platform_probe(): if resume fails, jump to err_destroy_mdev
  (skipping the suspend call, since the clock was never enabled)
- komeda_pm_resume(): propagate the error and skip
  drm_mode_config_helper_resume() on failure

This issue was found by code review without access to Komeda hardware.

Subject: [PATCH 4916/5214] drm/panthor: Always use the IRQ-safe variant when
 acquiring the fence lock

Since dma_fence objects can be shared with other subsystems, they may be
accessed from hardirq context in those drivers, and we have to take
that into account by also using the IRQ-safe variant when acquiring
the lock.

While at it, switch to the guard model.

Subject: [PATCH 4917/5214] drm/panthor: Keep the reset work disabled until
 everything is initialized

The reset work will sub-component reset helpers, which might not be
ready if the reset happens during initialization, leading to NULL
pointer dereferences or worse.

Avoid that by keeping the reset work disabled while we're initializing
those sub-components.

Subject: [PATCH 4919/5214] drm/panthor: Fix theoretical IOMEM access in
 suspended state

In theory, our hardirq handler can be called while the device (and
thus the panthor_irq) is suspended, because the IRQ line is shared.
In practice though, in all the designs we've seen, the line is only
shared within the GPU, and because sub-component suspend state is
consistent (all-suspended or all-resumed), we shouldn't end up with
an interrupt triggered while we're suspended.

Fix the problem anyway, if nothing else, for our sanity.

Subject: [PATCH 4924/5214] drm/panthor: Interrupt group start/resumption if
 group_bind_locked() fails

group_bind_locked() can fail if the MMU block is stuck. This is normally
a reset situation, but by the time we reset the GPU, we might have
tried to resume a group that's not resident, which will probably trip
out the FW. So let's avoid that by bailing out when group_bind_locked()
returns an error. We don't even try to start more groups because the
GPU will be reset anyway.

Subject: [PATCH 4925/5214] drm/panthor: Keep interrupts masked until they are
 needed

The autogenerated panthor_request_xx_irq() helpers unmask Mali
interrupts before we're sure we'll have a handler registered. For
non-shared IRQ lines, that's fine, but for shared ones, it might cause
an interrupt flood if the HW block raises an interrupt for any reason.

We could reworking the calls in panthor_request_xx_irq(), but it's just
simpler to let the caller decide when they are ready to handle interrupts
and call panthor_pwr_irq_resume() themselves. While at it, rework the
prototype to let users call panthor_pwr_irq_enable_events() explicitly
instead of passing an initial mask to panthor_request_pwr_irq().

Subject: [PATCH 4926/5214] bpf: Reject BPF_MAP_TYPE_INODE_STORAGE creation if
 BPF LSM is uninitialized

When CONFIG_BPF_LSM=y is set, BPF inode storage maps
(BPF_MAP_TYPE_INODE_STORAGE) are compiled into the kernel. However,
if the BPF LSM is not explicitly enabled at boot time (e.g. omitted
from the "lsm=" boot parameter), lsm_prepare() is never executed for
the BPF LSM.

Consequently, the BPF inode security blob offset
(bpf_lsm_blob_sizes.lbs_inode) is never initialized and remains at
its default compiled size of 8 bytes instead of being updated to a
valid offset past the reserved struct rcu_head (typically 16 bytes
or more).

When a privileged user creates and updates a BPF_MAP_TYPE_INODE_STORAGE
map, bpf_inode() evaluates inode->i_security + 8. This erroneously
aliases the struct rcu_head.func callback pointer at the beginning
of the inode->i_security blob. During subsequent map element cleanup
or inode destruction, writing NULL to owner_storage clears the queued
RCU callback pointer. When rcu_do_batch() later executes the queued
callback, it attempts an instruction fetch at address 0x0, triggering
an immediate kernel panic.

Fix this by introducing a global bpf_lsm_initialized boolean flag
marked with __ro_after_init. Set this flag to true inside bpf_lsm_init()
when the LSM framework successfully registers the BPF LSM. Gate map
allocation in inode_storage_map_alloc() on this flag, returning
-EOPNOTSUPP if the BPF LSM is in turn uninitialized.

This fail-fast approach prevents userspace from allocating inode
storage maps when the supporting BPF LSM infrastructure is absent,
avoiding zombie map states.

Subject: [PATCH 4927/5214] gpio: mt7621: avoid corruption of shared interrupt
 trigger state

The bank-shared fields like 'rising' and 'falling' are modified using
non-atomic read-modify-write operations. Since every gpio chip instance
represents an entire bank of 32 pins, if 'mediatek_gpio_irq_type()' is
called concurrently for different IRQs on the same bank a possible overwrite
of each other's configuration is possible. Thus, protect this state with
'gpio_generic_lock_irqsave' lock in the same way it is handled in irp_chip
'mediatek_gpio_irq_mask()' and 'mediatek_gpio_irq_unmask()' callbacks.

Subject: [PATCH 4928/5214] gpio: mt7621: more robust management of IRQ domain
 teardown

The driver uses devm_gpiochip_add_data() to register the GPIO chips which
means the devres subsystem will unregister them only after the function
'mt7621_gpio_remove()' returns. During the window between domain destruction
and devres unregistering the GPIO chips, the chips are still fully active.
If a consumer or userspace invokes gpiod_to_irq() during this window,
'mt7621_gpio_to_irq()' can dereference the already-freed irq domain pointer.
Thus, manage the IRQ domain teardown using 'devm_add_action_or_reset()' to
guarantee it is destroyed strictly after the GPIO chips are removed.

Subject: [PATCH 4929/5214] gpio: mt7621: be sure IRQ domain is created before
 exposing GPIO chips

Function 'mediatek_gpio_bank_probe()' registers three GPIO chips using
'devm_gpiochip_add_data()'. At this point, the chips become live and visible
to consumers. However, the IRQ domain isn't allocated and set up until
'mt7621_gpio_irq_setup()' is called after the GPIO chips setup finishes.
If a consumer requests a GPIO IRQ concurrently 'mt7621_gpio_to_irq()' can
be called and pass a NULL irq domain pointer irq_create_mapping(), that can
corrupt the mappings or cause a crash. Fix this possible problem seting up
irq domain before GPIO chips setup is performed.

Subject: [PATCH 4932/5214] tracing: eprobe: read the complete
 FILTER_PTR_STRING pointer

For a char * element in an event, the FILTER_PTR_STRING filter type is
used. When the event occurs, a pointer is stored in the ringbuffer.

If an eprobe references such a char * element of a "base event", the
stored pointer is truncated when it's read from the ringbuffer.

$ cd /sys/kernel/tracing
$ echo 'e rcu.rcu_utilization $s:x64 $s:string' > dynamic_events
$ echo 1 > tracing_on
$ echo 1 > events/eprobes/enable
$ sleep 1
$ echo 0 > events/eprobes/enable
$ cat trace
   <idle>-0  ...: (rcu.rcu_utilization) arg1=0x4f arg2=(fault)
   <idle>-0  ...: (rcu.rcu_utilization) arg1=0x2 arg2=(fault)

The problem is in get_event_field

	val = (unsigned long)(*(char *)addr);

addr points to the position in the ringbuffer where the pointer was
stored. The assignment reads only the lowest byte of the pointer.

Fix the cast to read the whole pointer. The output of the test above
is now

<idle>-0 ... arg1=0xffffffff81c7d3f3 arg2="Start scheduler-tick"
<idle>-0 ... arg1=0xffffffff81c57340 arg2="End scheduler-tick"

 fetching code") wrongly use @offset local variable during the parsing,
the offset value is added twice when dereferencing.
Reset the @offset after setting it in FETCH_OP_FOFFS.

Subject: [PATCH 4934/5214] tracing/fprobe: Fix NULL pointer dereference in
 fprobe_fgraph_entry()

fprobe_fgraph_entry() sizes a shadow-stack reservation in one walk of
the per-ip fprobe list and fills it in a second walk, both under
rcu_read_lock() only. A fprobe registered on an already-live ip can
become visible between the two walks, so the fill walk processes an
exit_handler the sizing walk did not count and used runs past
reserved_words. If the sizing walk counted nothing, fgraph_data is NULL
and the first write_fprobe_header() faults:

  Oops: general protection fault, probably for non-canonical address ...
  KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]

The list cannot be frozen across the two walks, so skip a node that does

imsic_early_acpi_init() allocates a firmware node before setting up the

freeing the allocated fwnode.

Free the fwnode and clear the global pointer on this error path, matching
the cleanup already done when imsic_early_probe() fails.

Subject: [PATCH 4938/5214] irqchip/ts4800: Fix missing chained handler cleanup
 on remove

The driver installs a chained handler for the parent interrupt during probe
using irq_set_chained_handler_and_data(), but the remove function does not
clear this handler. This leaves a dangling handler that may be called when
the parent interrupt fires after the driver has been removed, potentially
accessing freed memory and causing a kernel crash.

Additionally, the parent_irq obtained via irq_of_parse_and_map() is not
stored, making it inaccessible in the remove function. Moreover, interrupt
mappings created during probe are not properly disposed.

Fix this by:

   - Saving parent_irq in probe
   - Clearing the chained handler with NULL in ts4800_ic_remove()
   - Disposing all IRQ mappings before domain removal to prevent resource
     leaks

Subject: [PATCH 4943/5214] vfio: selftests: Add luuid to libvfio.mk's list of
 libraries, not to the Makefile

Link to the uuid library as part of libvfio.mk instead of as only linking
it via VFIO selftests' Makefile, as the whole point of providing libvfio.mk
is to allow linking the VFIO library functionality into KVM selftests,
without KVM selftests having to know the gory details or duplicate code.

Subject: [PATCH 4944/5214] bootconfig: fix NULL-pointer arithmetic in
 xbc_snprint_cmdline()

xbc_snprint_cmdline() is meant to be called twice: first with
buf=NULL, size=0 to probe the rendered length, then with a real
buffer to fill it (the standard snprintf() two-pass pattern). The
probe call makes the function compute "buf + size" (NULL + 0) and,
on every iteration, advance "buf += ret" from that NULL base and
pass the result back into snprintf().

Pointer arithmetic on a NULL pointer is undefined behavior. It is
harmless in the in-kernel callers today, but the follow-up patches
run this same code in the userspace tools/bootconfig parser at kernel
build time, where host UBSan / FORTIFY_SOURCE abort the build.

Track a running written length (size_t) instead of mutating @buf, and
only form "buf + len" when @buf is non-NULL. snprintf(NULL, 0, ...)
is itself well defined and returns the would-be length, so the
two-pass "probe then fill" usage returns identical byte counts.

Subject: [PATCH 4945/5214] selftests: net: bump default cmd() timeout to 20
 seconds

We always used 5 sec as the default command timeout. But soon after
it was introduced, David effectively made us ignore the timeout
(it was passed to process.communicate() as the wrong argument).
Gal recently fixed that, but turns out the 5 sec is not enough
for a lot of tests and setups. The fix caused regressions.

In particular running reconfig commands (e.g. XDP attach) on mlx5
with 32 rings and 9k MTU, on a heavily-debug-enabled kernel takes
more than 5 sec. The XDP installation command will time out after
5 sec but since the sleeps in the kernel are non interruptible
the command finishes anyway, leaving the XDP program attached,
but with non-zero exit code. defer()ed cleanups are not installed,
breaking the environment for subsequent tests.

Since "install XDP" is a pretty normal command a "point fix"
does not seem appropriate. 32 rings is a fairly reasonable
config, too, so we should just increase the timeout to 20 sec.

There's no real reason behind the value of 20.

Subject: [PATCH 4946/5214] sctp: fix addr_wq_timer race in sctp_free_addr_wq()

sctp_free_addr_wq() previously removed addr_wq_timer using timer_delete()
while holding addr_wq_lock. However, timer_delete() does not guarantee that
a currently running timer handler has completed.

This allows a race with sctp_addr_wq_timeout_handler(), where the handler
may still run after addr_waitq has been freed, acquire addr_wq_lock, and
access freed memory, leading to a use-after-free.

Fix this by calling timer_shutdown_sync() before taking addr_wq_lock.  This
guarantees that any in-flight timer handler has finished and prevents the
timer from being re-armed during teardown, making subsequent cleanup safe.

Subject: [PATCH 4947/5214] virtio_net: disable cb when NAPI is busy-polled

When busy-poll is active, napi_schedule_prep() returns false in
virtqueue_napi_schedule(), so virtqueue_disable_cb() is skipped.
The device may keep firing irqs until reaches virtqueue_napi_complete().
Under load (received == budget), it will lead to a large number
of spurious interrupts.

Fix it by disabling the callback at the virtnet_poll() entry.
This keeps the callback off while we poll and it is re-enabled by
virtqueue_napi_complete() when going idle.

Subject: [PATCH 4948/5214] cxgb4: Fix decode strings dump for T6 adapters

Depending on the value of chip_version, the correct decode set is selected.
However, the subsequent matching with the t4 encoding type in the if-else
block results in a reassignment, which leads to the loss of support for
t6_decode as well as reinitializing of values t4_decode and t5_decode.

The component history shows that the if-else block previously used for
this purpose, as well as the execution order, was not affected by the
change.
Furthermore, it is suggested by the execution order that the scenario with
overwriting and loss of support will be implemented.

Delete the if-else block.

Subject: [PATCH 4949/5214] selftests: drv-net: tso: don't touch dangerous
 feature bits

query_nic_features() detects which offloads depend on tx-gso-partial
by enabling everything, turning tx-gso-partial off, and seeing which
active features drop out. Enabling all hw features is dangerous:
we may end up enabling rx-fcs and loopback for example. For the
ice driver we end up getting into problems with feature dependencies
so the cleanup isn't successful either, and the test exits with
rx-fcs and loopback enabled.

Scope the feature probing just to segmentation bits.

Subject: [PATCH 4951/5214] net/sched: act_bpf: use rcu_dereference_bh() to
 read the filter

tcf_bpf_act() can run from the tc egress path, which holds only
rcu_read_lock_bh(), but reads prog->filter with rcu_dereference() and
trips lockdep:

  WARNING: suspicious RCU usage
  net/sched/act_bpf.c:47 suspicious rcu_dereference_check() usage!

The other tc actions and cls_bpf already use rcu_dereference_bh() here.

Subject: [PATCH 4952/5214] ksmbd: fix sd_ndr.data memory leak in
 ksmbd_vfs_set_sd_xattr

ndr_encode_v4_ntacl() allocates sd_ndr.data via kzalloc() at entry.
If any subsequent ndr_write_*() call returns error during encoding,
the allocated sd_ndr.data won't be freed and causes memory leak.

Move kfree(sd_ndr.data) into out label to ensure the buffer gets
released on all success and error return paths.

 sd_size error handling

1. When ndr_decode_v4_ntacl() fails, the code jumped to free_n_data
   which only freed n.data, skipping kfree(acl.sd_buf) and leaking
   the buffer. Zero-initialize struct xattr_ntacl acl, reorder error
   labels to out_free to release acl.sd_buf on all error paths.

2. if (acl.sd_size < sizeof(struct smb_ntsd)) is true, original code
   returned success without freeing sd_buf and left stale *pntsd.
   Set rc = -EINVAL before jumping to out_free to return error code and
   free buffer.

Subject: [PATCH 4955/5214] ksmbd: reject undersized DACLs before parsing ACEs

parse_dacl() limits the attacker-controlled ACE count by comparing it
with the number of minimal ACEs that fit in the DACL size. The DACL size
field is 16 bits, but the expression subtracts sizeof(struct smb_acl).
Because sizeof() is unsigned, a DACL size smaller than the ACL header
underflows to a large size_t.

A malicious client can reach this with:

SMB2_SET_INFO (InfoType=SMB2_O_INFO_SECURITY)
  -> smb2_set_info_sec()
  -> set_info_sec()
  -> parse_sec_desc()
  -> parse_dacl()
     -> init_acl_state(..., 0xffff)
     -> init_acl_state(..., 0xffff)
     -> kmalloc_objs(..., 0xffff)

Thus a malformed security descriptor can make num_aces pass the guard
and drive large temporary ACL state and pointer-array allocations.

Reject DACLs smaller than struct smb_acl before doing the subtraction,
so the ACE count check cannot be bypassed by the underflow.

Subject: [PATCH 4956/5214] ksmbd: validate num_subauth when copying ACE in
 set_ntacl_dacl

set_ntacl_dacl() copies each ACE from the attacker-controlled stored
security descriptor verbatim into the response DACL without checking
sid.num_subauth. The ACE bytes (including an unchecked num_subauth)
originate from an authenticated SMB2_SET_INFO(SecInfo=DACL) that is
stored raw via ksmbd_vfs_set_sd_xattr(); parse_dacl() rejects a bad ACE
with `break` rather than an error, so parse_sec_desc() still returns
success and the malformed SD reaches the xattr intact.

On a subsequent SMB2_QUERY_INFO(SecInfo=DACL) for an inode carrying a
POSIX access ACL, build_sec_desc() -> set_ntacl_dacl() ->
set_posix_acl_entries_dacl() walks the copied ACEs and reads

    ntace->sid.sub_auth[ntace->sid.num_subauth - 1]

with num_subauth taken straight from the stored SD. Since sub_auth[]
is fixed at SID_MAX_SUB_AUTHORITIES (15), a crafted num_subauth (e.g.
255) drives an out-of-bounds heap read of ~1 KB with an offset fully
controlled by an authenticated client.

The sibling functions already gate this field:
  parse_dacl()    -- num_subauth == 0 || > SID_MAX_SUB_AUTHORITIES
  parse_sid()     -- num_subauth > SID_MAX_SUB_AUTHORITIES
  smb_copy_sid()  -- min_t(u8, num_subauth, SID_MAX_SUB_AUTHORITIES)
set_ntacl_dacl() is the lone inconsistent path that omits the check.

Add the same num_subauth validation in set_ntacl_dacl() before copying
the ACE, matching the gate already enforced by parse_dacl().

Subject: [PATCH 4957/5214] ksmbd: avoid zeroing the read buffer in smb2_read()

smb2_read() allocates the read payload buffer with kvzalloc(), zeroing up
to max_read_size bytes (1MB or more with multichannel) on every read,
only to immediately overwrite the region with file data via kernel_read().

The zero-fill is pure overhead: ksmbd_vfs_read() returns the number of
bytes actually read ('nbytes'), and only those nbytes are ever consumed -
they are pinned into the response iov (ksmbd_iov_pin_rsp_read()), sent
over the RDMA channel (smb2_read_rdma_channel()), or copied by the
compression path (ksmbd_compress_response() uses iov_len == nbytes). The
ALIGN(length, 8) tail padding and any short-read remainder are never read
or transmitted, so they need not be initialized.

Use kvmalloc() instead to skip the redundant zeroing. This reduces CPU
and memory-bandwidth usage on large sequential reads.

Subject: [PATCH 4958/5214] ksmbd: fix credit charge calculation for SMB2
 QUERY_INFO

smb2_validate_credit_charge() computes the credit charge a request is
allowed to consume from the payload size:

  CreditCharge = (max(SendPayloadSize, ResponsePayloadSize) - 1)/65536 + 1

For SMB2 QUERY_INFO, the server must validate CreditCharge based on the
*maximum* of InputBufferLength and OutputBufferLength. ksmbd instead
summed the two lengths, which overestimates the required charge.

As a result a single-credit QUERY_INFO whose InputBufferLength and
OutputBufferLength each fit in 64KB but whose sum exceeds 64KB is
rejected with STATUS_INVALID_PARAMETER, even though it is a valid
request. IOCTL already uses max() of the request and response sizes;
make QUERY_INFO consistent by feeding InputBufferLength as the request
length and OutputBufferLength as the expected response length so that
smb2_validate_credit_charge() takes their maximum.

Subject: [PATCH 4959/5214] ksmbd: fix outstanding credit leak on abort and
 error paths

smb2_validate_credit_charge() adds the request's CreditCharge to
conn->outstanding_credits when an SMB2 PDU is received, and
smb2_set_rsp_credits() subtracts it again when the response is built.
However smb2_set_rsp_credits() only runs on the normal response path:

  - __process_request() returning SERVER_HANDLER_ABORT (unimplemented
    command, command index out of range, signature check failure, or a
    handler that sets send_no_response such as a cancelled blocking
    lock) breaks out of the processing loop before set_rsp_credits() is
    called;
  - smb2_set_rsp_credits() itself returns early with -EINVAL (total
    credit overflow or insufficient credits) before the subtraction.

On all of these paths the charge added at receive time is never
returned, so conn->outstanding_credits only grows. Because a client can
repeatedly trigger them (e.g. by sending unimplemented commands or by
issuing and cancelling blocking locks), outstanding_credits eventually
reaches total_credits and smb2_validate_credit_charge() then rejects
every subsequent request, wedging the connection.

Record the charge that was added in work->credit_charge and release any
charge still pending at the single send. exit point of
__handle_ksmbd_work(), which all abort and error paths fall through to.
smb2_set_rsp_credits() clears work->credit_charge once it has returned
the charge so the response path is unchanged and the credit is never
released twice. Paths that never charged a credit (no multi-credit
support, validation failure) leave work->credit_charge at zero and are
unaffected.

Subject: [PATCH 4960/5214] ksmbd: annotate oplock list traversals under m_lock

session_fd_check() and ksmbd_reopen_durable_fd() walk ci->m_op_list with
list_for_each_entry_rcu() while holding ci->m_lock for write. That is
the local inode/oplock serializer, but the RCU-list iterator does not
currently tell lockdep about it.

Pass lockdep_is_held(&ci->m_lock) to these iterators so
CONFIG_PROVE_RCU_LIST can see the rwsem protection already in place.

This was found by our static analysis tool and then manually reviewed
against the current tree. The dynamic triage evidence is a
target-matched CONFIG_PROVE_RCU_LIST warning; the change is limited
to documenting the existing protection contract.

This is a lockdep annotation cleanup. It does not change oplock list
lifetime or durable-handle behavior.

Subject: [PATCH 4962/5214] ksmbd: don't hold ci->m_lock while waiting for a
 lease break ack

When a cifs.ko client caches a read-handle (RH) lease via deferred close
and a conflicting open arrives, ksmbd breaks the lease and waits for the
acknowledgment in wait_for_break_ack() for up to OPLOCK_WAIT_TIME (35s).
__smb_break_all_levII_oplock() runs that wait while holding ci->m_lock
for read.

cifs.ko reacts to a handle-lease break by closing the deferred handle
rather than sending a lease break acknowledgment. That close path
(close_id_del_oplock() -> opinfo_del()) takes ci->m_lock for write and
is exactly what would wake the waiter, but it blocks on the read lock
held by the waiting thread. The break is then resolved only by the 35s
timeout, so xfstests generic/001 takes ~78s with leases enabled versus
~4s with oplocks only.

Collect the target opinfos (each pinned with a reference) while holding
ci->m_lock, then break them after releasing it, matching how
smb_grant_oplock() already breaks a conflicting lease using only a
reference.  The reference keeps the opinfo (and its conn and lease)
alive across the unlocked window, and a close racing the break is
handled by the existing OPLOCK_CLOSING state check. Apply the same fix
to the parent lease break paths.

Subject: [PATCH 4964/5214] ksmbd: fix use-after-free of fp->owner.name in
 durable handle owner check

Two concurrent SMB2 durable reconnects (DH2C/DHnC) on the same
persistent_id race the fp->owner.name compare-read in
ksmbd_vfs_compare_durable_owner() against the kfree() in
ksmbd_reopen_durable_fd()'s reopen-success path. fp->owner.name is a
standalone kstrdup() buffer whose lifetime is independent of the fp
refcount, and the two sites share no lock: the compare reads the buffer
while the reopen frees it, so the strcmp() can dereference freed memory.

Commit 7ce4fc40018d ("ksmbd: fix durable reconnect double-bind race in
ksmbd_reopen_durable_fd") made the fp->conn claim atomic under
global_ft.lock (closing the owner.name double-free and the ksmbd_file
write-UAF), but the compare-read versus reopen-free pair was left
unserialized.

  BUG: KASAN: slab-use-after-free in strcmp+0x2c/0x80
  Read of size 1 by task kworker
    strcmp
    ksmbd_vfs_compare_durable_owner
    smb2_check_durable_oplock
    smb2_open
  Freed by task kworker:
    kfree
    ksmbd_reopen_durable_fd
    smb2_open
  Allocated by task kworker:
    kstrdup
    session_fd_check
    smb2_session_logoff
  The buggy address belongs to the cache kmalloc-8

Serialize both sides of the race with fp->f_lock.  The global durable
file-table lock still protects the durable reconnect claim, but
fp->owner.name is per-open state and does not need to block unrelated
durable table lookups or reconnects.  The teardown is left at its
existing location after the reopen-success point so that an __open_id()
rollback still retains owner.name for a later legitimate reconnect to
verify.

Subject: [PATCH 4965/5214] ksmbd: close superseded durable handles through
 refcount handoff

ksmbd_close_disconnected_durable_delete_on_close() collects disconnected
durable handles for a name being superseded by a new delete-on-close
open, drops ci->m_lock, then closes each collected handle directly with
__ksmbd_close_fd().

That bypasses the FP_CLOSED and refcount handoff used by the other close
paths. If a durable reconnect or the durable scavenger already took a
reference to the same fp, the direct __ksmbd_close_fd() can free the
ksmbd_file while that other holder still owns a live reference.

Claim the disconnected durable handle before unlinking it from m_fp_list.
While holding ci->m_lock and global_ft.lock, only take ownership when the
durable lifetime reference is the only remaining reference. Then take a
transient reference, remove the fp from global_ft, mark it FP_CLOSED, and
move it to the local dispose list. If another holder already has a
reference, leave the fp linked and let that holder complete its path.

The dispose loop then drops both references owned by the claim. This keeps
the force-close path in the same refcount handoff model as the durable
scavenger and avoids leaving a live reconnected fp detached from
m_fp_list.

Subject: [PATCH 4966/5214] ksmbd: snapshot previous oplock state before
 durable checks

smb_grant_oplock() checks the previous oplock holder's o_fp to decide
whether a durable handle should be invalidated when the oplock break
cannot be delivered. prev_opinfo is obtained with opinfo_get_list(),
which pins only the oplock_info. It does not pin the ksmbd_file stored
in opinfo->o_fp.

A concurrent last close can unlink the opinfo from ci->m_op_list under
ci->m_lock and then free the ksmbd_file. The oplock_info can still be
kept alive by the refcount taken by opinfo_get_list(), but o_fp may
already point at freed memory by the time smb_grant_oplock() reads
is_durable, conn, or tcon.

Snapshot the previous holder's durable state while ci->m_lock is held,
then use only the copied values after dropping the lock. This keeps the
o_fp lifetime tied to the inode lock without taking an extra ksmbd_file
reference. Taking such a reference is unsafe here because smb_grant_oplock()
does not necessarily have the previous holder's session work, and dropping
the temporary reference can otherwise become the final putter.

Subject: [PATCH 4967/5214] ksmbd: fix app-instance durable supersede session
 UAF

ksmbd_close_fd_app_instance_id() looks up a prior durable handle by
AppInstanceId and closes it through opinfo->sess->file_table. This is
unsafe after the original session has been torn down. session_fd_check()
preserves reconnectable durable handles in the global table and clears
opinfo->conn/fp->conn, but opinfo->sess can still point to the freed
ksmbd_session.

Use opinfo->conn as the orphan sentinel, but make the check reliable by
serializing it with session_fd_check(). That path clears opinfo->conn
under fp->f_ci->m_lock, so hold the same lock while testing opinfo->conn
and while dereferencing opinfo->sess->file_table. Also avoid closing
through the session file table if the volatile id has already been
unpublished by session teardown.

Durable reconnect must keep the two fields consistent. Rebinding only
opinfo->conn leaves opinfo->sess pointing at the old freed session, so
a later app-instance supersede can pass the conn check and write-lock the
freed session's file table. Clear opinfo->sess when preserving a durable
handle during session teardown, and set it to the reconnecting session
when opinfo->conn is rebound in ksmbd_reopen_durable_fd().

Ensure the EDID provided min/max vfreq are valid. Most scenarios are
already covered (by coincidence) through the checks in
intel_vrr_is_capable() and intel_vrr_is_in_range(), but be more explicit
about it. At worst, a zero min_vfreq could lead to a division by zero in
intel_vrr_compute_vmax().

Subject: [PATCH 4971/5214] pinctrl: meson: restore non-sleeping GPIO access

Commit 28f240683871 ("pinctrl: meson: mark the GPIO controller as
sleeping") set gpio_chip.can_sleep = true to work around
gpio-shared-proxy holding a spinlock across a sleeping pinctrl config
path. That locking bug is now fixed in the shared-proxy itself ("gpio:
shared-proxy: always serialize with a sleeping mutex"), so the
controller-wide workaround is no longer needed; the meson GPIO
controller does not sleep.

meson_gpio_get/set/direction_* access MMIO through regmap. The
regmap_mmio bus uses fast I/O (spinlock) locking, so these value
callbacks do not contain sleeping operations. Since gpio_chip.can_sleep
describes the get/set value path, restore can_sleep = false.

Marking the controller sleeping also broke atomic value consumers such
as w1-gpio (1-Wire bitbang): w1_io.c runs its read time slot under
local_irq_save() and uses the non-cansleep gpiod_set_value() /
gpiod_get_value(), which with can_sleep=true trigger WARN_ON(can_sleep)
in gpiolib on every transferred bit (from w1_gpio_write_bit() /
w1_gpio_read_bit() via w1_reset_bus() and w1_search()). The printk and
stack dump inside the IRQs-off, microsecond-scale time slot destroy the
bit timing, so reset/presence detection and ROM search fail: the bus
master registers but w1_master_slave_count stays at 0 and no devices
are found. Verified on an Amlogic A113X board (DS18B20 on GPIOA_14):
with can_sleep restored to false the warnings are gone and the sensor
is detected and read again.

This must not be applied or backported without the shared-proxy locking
fix above; otherwise the original Khadas VIM3 splat returns on boards
that genuinely share a meson GPIO.

Subject: [PATCH 4972/5214] xen/pvcalls: bound backend response req_id before
 indexing rsp[]

pvcalls_front_event_handler() takes req_id directly from the
backend-supplied ring response and uses it to index the fixed-size
bedata->rsp[] array for a memcpy() and a store, with no range check. A
malicious or buggy backend can set req_id past PVCALLS_NR_RSP_PER_RING
and drive an out-of-bounds write past the bedata allocation.

req_id was also declared int while the wire field rsp->req_id is u32, so
a range check on the signed value alone is insufficient: a backend
req_id of 0xffffffff becomes -1, passes a >= PVCALLS_NR_RSP_PER_RING
test and indexes bedata->rsp[-1]. Declare req_id as u32 so a single
bound covers both ends.

A backend that sends an out-of-range req_id has violated the wire
protocol, so rather than silently dropping the response, log once and
stop trusting the backend: set bedata->disabled. The event handler then
ignores further responses, and the request paths that wait for a
response return -EIO instead of blocking forever. This mirrors the
fatal-error handling xen-netback uses (xenvif_fatal_tx_err()).

The pvcalls frontend currently trusts its backend, so this is not a
classic-Xen security issue, but it matters for hardening PV frontends
against malicious backends (confidential and disaggregated deployments).

Subject: [PATCH 4973/5214] xen: Replace __ASSEMBLY__ with __ASSEMBLER__ in
 header files

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.

This is a completely mechanical patch (done with a simple "sed -i"
statement).

Subject: [PATCH 4974/5214] xen/gntdev: fix error handling in ioctl

When gntdev_ioctl_map_grant_ref() fails to copy the operation result
back to userspace after successfully adding the mapping to the list,
the error path returns -EFAULT without releasing the reference
acquired by gntdev_alloc_map(). The mapping remains in priv->maps
with a refcount of 1, causing a memory leak and a dangling list
entry.

Additionally, gntdev_add_map() may modify map->index to avoid overlap
with existing mappings. Therefore, the index returned to userspace
must be obtained after gntdev_add_map() completes.

Fix this by holding the mutex across gntdev_add_map(), retrieving
the correct index, and copy_to_user(). If copy_to_user() fails,
remove the mapping from the list and release the reference while
still holding the lock.

Cc: stable@vger.kernel.org

Fix these issues by properly handling all error cases.

grant_references() allocates a private grant-reference head before
claiming references for the page directory and, for guest-owned buffers,
the data pages. The success path frees the remaining head, but claim
failures and grant_refs_for_buffer() errors return immediately.

Unwind through a common exit path so the private grant-reference head is
released even when granting fails part-way through setup. The caller
still tears down any references already stored in buf->grefs.

module parameter values are rejected by parameter parsing.

This also prepares the limit check for overflow-safe unsigned

Subject: [PATCH 4977/5214] xen/gntalloc: validate grant count before
 allocation

gntalloc_ioctl_alloc() allocates the grant-id array before checking
whether the requested count fits within the global grant limit. Counts
above that limit cannot succeed, so reject them before the
user-controlled allocation reaches kcalloc().

Use a subtraction-based check while holding gref_mutex so adding the
requested count cannot wrap. Also cast the count before advancing the
per-file index so the page-size multiplication is performed in 64-bit
arithmetic.

Subject: [PATCH 4978/5214] net/sched: dualpi2: clear stale classification on
 filter miss

DualPI2 leaves previous classification state attached to an skb when
filter classification returns no match.  The enqueue path can then act
on stale state from an earlier classification attempt.

A filter miss should fall back to the default class without reusing old
per-packet classification data.

Initialize the classification result to CLASSIC before running the
classifier.  Explicit L4S, priority, and successful filter
classification can still override that default.

Subject: [PATCH 4979/5214] xenbus: reject unterminated directory replies

split_strings() walks each directory entry with strlen(). Although the
transport adds a terminator after the reply buffer, a malformed reply
without a final NUL inside its advertised length would let that walk
cross the protocol payload boundary.

Reject such replies before counting the strings. Report the protocol
violation once and return -EIO to the caller.

HHF reset does not clear the classifier state used to identify heavy
hitters.  Packets after reset can therefore be scheduled using flow
history from before the reset.

The reset operation should return the qdisc to an empty state.

Clear the heavy-hitter classifier tables when HHF is reset.

Subject: [PATCH 4981/5214] bpf: Support for hardening against JIT spraying

The BPF JIT allocator packs many small programs into larger executable
allocations and reuses space within those allocations as programs are
loaded and freed. When fresh code is written into space that a previous
program occupied, an indirect jump into the new program can reuse a branch
prediction left behind by the old one.

Flush the indirect branch predictors before reusing JIT memory so that
indirect jumps into a newly written program don't reuse predictions from an
old program that occupied the same space.

Introduce bpf_arch_pred_flush_enabled static key and bpf_arch_pred_flush
static call for flushing the branch predictors on JIT memory reuse.
Architectures that need a flush, can update it to a predictor flush
function. By default, its a NOP and does not emit any CALL.

Allocations larger than a pack are not covered by this flush. That is safe
because cBPF programs (the unprivileged attack surface) are bounded well
below a pack size. Issue a warning if this assumption is ever violated
while the flush is active.

Subject: [PATCH 4982/5214] x86/bugs: Enable IBPB flush on BPF JIT allocation

Enable hardening against JIT spraying when Spectre-v2 mitigations are in
use. Specifically, issue an IBPB flush on BPF JIT memory reuse. Skip
enabling the IBPB flush if the BPF dispatcher is already using a retpoline
sequence.

This hardening applies only when BPF-JIT is in use. Guard the enabling
under CONFIG_BPF_JIT so that bugs.c still builds with CONFIG_BPF_JIT=n.

Subject: [PATCH 4983/5214] bpf: Restrict JIT predictor flush to cBPF

Currently predictor flush on memory reuse is done for all BPF JIT
allocations, but only cBPF programs can be loaded by an unprivileged user.
eBPF is privileged by default, and flushing predictors for all CPUs on
every eBPF reuse penalizes the common case for no security benefit.

eBPF allocations can be frequent on busy systems, only flush predictors
for cBPF programs. Trampoline and dispatcher allocations also skip the
flush as they are eBPF-only.

Subject: [PATCH 4984/5214] bpf: Skip redundant IBPB in pack allocator

bpf_prog_pack_alloc() issues IBPB on all CPUs on every cBPF allocation,
even when reusing chunks from an existing pack where no new memory was
touched since the last IBPB.

Since IBPB on all CPUs is heavy, Dave Hansen suggested to track allocation
since last IBPB, and only issue IBPB at reuse for the chunks that have not
seen an IBPB since they were last freed.

Track per-pack whether an IBPB is needed via arch_flush_needed. Set it when
allocating a chunk, reset on IBPB flush. On reuse, conditionally issue the
flush. Since IBPB invalidates all BTB entries, clear the flag on all packs
after flushing.

Subject: [PATCH 4985/5214] bpf: Prefer packs that won't trigger an IBPB flush
 on allocation

Currently BPF pack allocator picks the chunks from the first available
pack. While this is okay, it naturally leads to more frequent flushes
when there are multiple packs in the system that weren't used since the
last flush.

As an optimization prefer allocating the new programs from packs that
are unused since last flush. When all packs are dirty, allocation forces
a flush and marks all packs clean.

Below are some future optimizations ideas:

  1. Currently, the "dirty" tracking is only done at the pack-level.
     Flush frequency can further be reduced with chunk-level tracking.
     This requires a new bitmap per-pack to track the dirty state.
  2. IBPB flush is done on all CPUs, even if only a single CPU ran the
     BPF program. On a system with hundreds of CPUs this could be a
     major bottleneck forcing hundreds of IPIs to deliver the flush.
     The solution is to track the CPUs where a BPF program ran, and
     issue IBPB only on those CPUs.
  3. Avoid IBPB when flush is already done at other sources (e.g.
     context switch).

Subject: [PATCH 4986/5214] bpf: Prefer dirty packs for eBPF allocations

The pack allocator only flushes predictors when reusing a dirty pack for
cBPF, eBPF allocations never trigger a flush. Currently, eBPF picks the
first free pack, which could be a clean pack. As an optimization, leaving
a clean pack for cBPF can avoid flushes.

Prefer dirty packs for eBPF and keep clean packs free for cBPF. This
mirrors the existing cBPF preference for clean packs: each program kind
prefers the pack that avoids an extra flush, and falls back to the other
kind only when no preferred pack has room. eBPF reuse of a dirty pack is
harmless since eBPF being privileged does not flush.

Subject: [PATCH 4989/5214] xfs: release dquot buffer after dqflush failure

xfs_qm_dqpurge() gets a locked buffer from xfs_dquot_use_attached_buf().
If xfs_qm_dqflush() fails, the error path skips xfs_buf_relse() and then
calls xfs_dquot_detach_buf(), which tries to lock the same buffer again.

Release the buffer after xfs_qm_dqflush() returns so the error path drops
the caller hold and unlocks the buffer before the dquot is detached,
matching the other dqflush callers.

Subject: [PATCH 4990/5214] xfs: fix memory leak in
 xfs_dqinode_metadir_create()

If xfs_metadir_create() fails in xfs_dqinode_metadir_create(), the current
code returns directly, leaking the allocated update and transaction state.
If the subsequent commit fails, the caller-owned inode reference is left
behind.

Fix this memory leak by routing the create failure path through
xfs_metadir_cancel().  For both create and commit failures, finish and
release any inode returned to the caller, mirroring the unwind pattern in
xfs_metadir_mkdir().

The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.

An x86_64 allyesconfig build showed no new warnings. Runtime validation
used kprobe fault injection during `mount -o uquota` on a metadir XFS
image. Injecting xfs_metadir_create() reproduced the old active-update path
that left mount stuck later in mount setup; after this change, the same
injection reported cancel_hits=1 and irele_hits=1. Injecting
xfs_metadir_commit() exercised the old inode-reference leak path; after
this change, it reported irele_hits=1.

Subject: [PATCH 4991/5214] xfs: use null daddr for unset first bad log block

xlog_do_recovery_pass() may return before setting first_bad.  The caller
must distinguish that case from an error at a valid log block, including
block zero after the log wraps.

Initialize first_bad to XFS_BUF_DADDR_NULL and test it explicitly before
treating the error as a torn write.

Subject: [PATCH 4992/5214] drm/dp_mst: Handle torn-down topology gracefully in
 drm_dp_mst_topology_queue_probe()

A hotplug or link-loss event can tear down the MST topology
(setting mgr->mst_state = false and mgr->mst_primary = NULL) concurrently
with a caller invoking drm_dp_mst_topology_queue_probe(). Since the check
is already performed under mgr->lock, the condition is not a programming
error but a valid race -- the topology was valid when the caller decided
to call this function, but was torn down before the lock was acquired.

Replace the drm_WARN_ON() with a graceful early return. This eliminates
spurious kernel warnings and the resulting compositor crashes observed
when connecting/disconnecting DP MST monitors, while keeping the correct
behavior of doing nothing when MST is not active. A drm_dbg_mst() trace
is added so the skipped probe remains observable under MST debug logging.

The existing WARN_ON(mgr->mst_primary) in drm_dp_mst_topology_mgr_set_mst()
already catches the case where the topology is initialized twice, so no
diagnostic coverage is lost.

Subject: [PATCH 4993/5214] ACPICA: Define acpi_ut_safe_strncpy() as
 strscpy_pad() alias

Commit 292db66afd20 ("ACPICA: Unbreak tools build after switching over
to strscpy_pad()") added an #ifdef based on a __KERNEL__ check which is
sort of nasty to the acpi_ut_safe_strncpy() definition to unbreak ACPICA
tools builds broken by commit 97f7d3f9c9ac ("ACPICA: Replace strncpy()
with strscpy_pad() in acpi_ut_safe_strncpy()").  However, that #ifdef
effectively produces dead code when tools are built because they don't
call acpi_ut_safe_strncpy().

Accordingly, drop the existing definition of acpi_ut_safe_strncpy() and
define it as a strscpy_pad() alias.

__xfs_buf_ioend can only resubmit the buffer for asynchronous
writes, which means the retry handling xfs_buf_iowait is not needed.

Because of this can stop returning a value from __xfs_buf_ioend and
just release the buffer for async I/O that does not require retries.

Also drop the __-prefix now that the semantics are straight forward.

Subject: [PATCH 4998/5214] ALSA: usx2y: us144mkii: fix work UAF on disconnect

tascam_disconnect() cancels capture_work and midi_in_work before
usb_kill_anchored_urbs() kills the capture/MIDI-in URBs.  Those URBs
self-resubmit, and their completion handlers reschedule the work.

A URB that completes in the small window between cancel_work_sync() and
usb_kill_anchored_urbs() therefore re-arms the work after its only
cancel.  Nothing cancels it again before snd_card_free() frees the
card-private tascam structure, so the work handler then runs on freed
memory.

Kill the anchored URBs before cancelling the work; once the work is
cancelled no remaining URB can complete to re-arm it.

Subject: [PATCH 4999/5214] ASoC: SOF: validate probe info element counts

Probe information replies contain a firmware-provided element count. IPC3
uses that count to copy an array, then returns the unchecked count to its
caller. A short reply can therefore make the caller walk beyond the copied
array.

IPC4 similarly uses the count both to allocate the destination array and
to walk the reply. On 32-bit systems the allocation size can wrap, while on
all systems an excessive count reads beyond the reply payload.

Validate each count against the actual reply size before copying or
allocating the array, and use kcalloc() for the IPC4 allocation.

Subject: [PATCH 5000/5214] afs: handle CB.InitCallBackState3 requests without
 a server record

The cache manager callback path now attaches the server record to an
incoming call through the rxrpc peer's app data.  That association is
not guaranteed to exist for every callback request, and most callback
handlers already tolerate that case.

Make CB.InitCallBackState3 follow the same pattern by checking whether a
server record was attached before using it.  If the peer is not mapped
to a server record, trace the request and ignore it, matching the
existing behaviour for other unmatched callback requests.

This keeps the callback handler consistent with the rest of the cache
manager service and avoids depending on peer state that may not be
available for a given request.

Subject: [PATCH 5001/5214] fs: refuse O_TMPFILE creation with an unmapped
 fsuid or fsgid

vfs_tmpfile() never checked that the caller's fsuid and fsgid map into
the filesystem.  On an idmapped mount whose idmapping does not cover the
caller's fs{u,g}id, the ->tmpfile() instance initializes the new inode
through inode_init_owner(), where mapped_fsuid()/mapped_fsgid() return
INVALID_UID/INVALID_GID, and the tmpfile ends up owned by (uid_t)-1.

Every other creation path already refuses this: may_o_create() (O_CREAT)
and may_create_dentry() (mkdir, mknod, symlink, link) bail out with
-EOVERFLOW via fsuidgid_has_mapping() precisely so that an object cannot
be created with an owner the filesystem cannot represent.  An O_TMPFILE
is no exception: it is created I_LINKABLE and linkat(2) can splice it
into the namespace afterwards, so the same guarantee must hold.

Add the missing fsuidgid_has_mapping() check to vfs_tmpfile().  On a
non-idmapped mount the caller's fs{u,g}id always map in the superblock's
user namespace, so this is a no-op there and only takes effect on an
idmapped mount that does not map the caller.  It applies to every
filesystem that sets FS_ALLOW_IDMAP and implements ->tmpfile() (tmpfs,
ext4, btrfs, xfs, f2fs, ...), and to overlayfs, whose upper-layer
tmpfile creation funnels through vfs_tmpfile() via backing_tmpfile_open().

Subject: [PATCH 5003/5214] selftests/filesystems: test O_TMPFILE creation on
 idmapped mounts

Add a regression test for the fsuidgid_has_mapping() check in
vfs_tmpfile().  It idmaps a detached tmpfs mount so that the
caller-visible id range [0, 10000) maps onto the on-disk range
[10000, 20000) and checks that:

  - a caller whose fsuid/fsgid fall outside that range cannot create an
    O_TMPFILE through the mount and gets -EOVERFLOW instead of an inode
    owned by (uid_t)-1;

  - a mapped caller can create an O_TMPFILE, link it into the namespace,
    and the ownership round-trips through the mount idmap: it is reported
    as 0 through the mount and stored as 10000 on the underlying tmpfs.

The test runs entirely as root and uses setfsuid()/setfsgid() to become
the unmapped caller, so it needs no helper user.  The layer directory is
world-writable so that an unmapped caller still clears the directory
permission check and reaches the fsuidgid_has_mapping() test.

Subject: [PATCH 5004/5214] afs: fix NULL pointer dereference in afs_get_tree()

afs_alloc_sbi() uses kzalloc for memory allocation. And, if
ctx->dyn_root is not null, as->cell and as->volume are null.
In trace_afs_get_tree() they are dereferenced.

Subject: [PATCH 5006/5214] afs: Remove setting of AS_RELEASE_ALWAYS for
 symlinks and mountpoints

Regular AFS files correctly use afs_file_aops which have release_folio
set as netfs_release_folio, so AS_RELEASE_ALWAYS is valid for them
when fscache is enabled (set via afs_vnode_set_cache()).
Symlinks and mountpoints in AFS use afs_dir_aops, which does not provide
a release_folio callback. However, afs_apply_status() unconditionally
calls mapping_set_release_always() for these.

In such case when memory management code attempts to release folios,
filemap_release_folio() checks folio_needs_release() which
returns true due to AS_RELEASE_ALWAYS being set. Since there is no
release_folio callback, it falls through to try_to_free_buffers(),
which at present expects buffer_heads to be not null. For symlinks
and mountpoints without buffer_heads, this causes pointer dereference.

[dh: Added more bits that were missed]

Subject: [PATCH 5007/5214] afs: Fix directory inode initialisation order

Fix afs_inode_init_from_status() to call afs_set_netfs_context() before the
switch to do file type-specific initialisation because local directory
changes don't get uploaded to the server, only stored in the cache.

This requires that the file size be set before, so move that up too.

Without this, NETFS_ICTX_SINGLE_NO_UPLOAD as set on directories gets
clobbered.

Subject: [PATCH 5011/5214] afs: Fix bulk lookup malfunction due to change in
 dir_emit() API

afs_do_lookup() and afs_do_lookup_one() use the same directory parsing code
as afs_readdir() and were supplying alternative dir_context actors to
retrieve dirents, but because lookup needs the vnode's uniquifier as part
of the reference, but not the DT flags, the uniquifier was being passed in
the dt flags argument to the lookup actors.

Unfortunately, commit c644bce62b9c, added to fix overlayfs with fuse, broke
this by masking off part of the uniquifier.  This doesn't matter enough to
be directly noticeable, instead causing bulk advance inode lookups to fail
(which are retried later) and may cause dir revalidation to malfunction if
the uniquifier is changed by masking.

Fix this by making the afs directory parsing code take special ->actor
values of AFS_LOOKUP or AFS_LOOKUP_ONE instead that tell it to call
afs_lookup_filldir() or afs_lookup_one_filldir() directly rather than going
through dir_emit().  dir_emit() is still used for readdir.

Subject: [PATCH 5013/5214] afs: Fix reinitialisation of the inode, in
 particular ->lock_work

It seems that initalising afs_vnode::lock_work a single time in the slab's
init function isn't sufficient for work_structs.  This results in the
DEBUG_OBJECTS debugging stuff producing a warning occasionally when running
the generic/131 xfstest:

Fix this by reinitialising ->lock_work after allocating an inode.

Also, flush ->lock_work when the inode is being evicted to make sure it's
not still running.

Subject: [PATCH 5014/5214] afs: Fix callback service message parsers to pass
 through -EAGAIN

The AFS filesystem client uses an rxrpc server to listen for callback
notifications.  Each callback call type handler has a delivery function
that parses the incoming request stream, and this should return -EAGAIN the
last packet hasn't yet been seen, but all currently queued received data is
consumed.  afs_extract_data() does this, but the -EAGAIN return is switched
to 0 inadvertantly

Fix callback service message parsers to pass through -EAGAIN

locks cannot be taken there.

Subject: [PATCH 5020/5214] afs: Fix premature cell exposure through /afs

AFS cell records are prematurely exposured through the /afs dynamic root by
virtue of adding them immediately to the net->cells_dyn_ino IDR when the
cell is allocated rather than when it is added to the lookup tree.  This
allows a candidate record to be accessed, even if it's actually a duplicate
or not published yet.

Fix this by not adding the cell to cells_dyn_ino until it's confirmed
non-duplicate and is being published.  A flag is then used to record
whether it is added to the IDR to make removal from the IDR conditional.

Subject: [PATCH 5023/5214] MAINTAINERS: take over vboxsf from Hans de Goede

I talked to Hans de Goede about two weeks ago in person. He expressed he
would rather have someone else maintain vboxsf and was thinking about
orphaning it. Since I am already doing filesystem stuff anyway, I am
fine with doing this. (vboxsf is a thin layer between the vfs and the
Virtual Box guest device driver).

I have no major plans for vboxsf, but I do want to support passing
physical addresses to the host; the communication protocol seems to
allow for it and it would mean we can get rid of some kmap calls.

If bio_iov_iter_get_pages() or the bounce helper succeeds but builds a

Subject: [PATCH 5025/5214] proc: only bump parent nlink when registering
 directories
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

proc_register() increments the parent directory's link count for every
entry it registers, while remove_proc_entry() and remove_proc_subtree()
decrement it only when the removed entry is a directory.  Regular files
thus inflate the parent's count while they exist, and leak one link
permanently on every create and remove cycle.

For example, /proc/bus/pci/00 with twenty-two device files and no
subdirectories reports nlink 24 instead of 2, and SR-IOV VF enable
and disable cycles, each creating and removing the VF config space
entries under /proc/bus/pci/<bus>, inflate the link count of that
directory without bound.

Before commit e06689bf5701 ("proc: change ->nlink under
proc_subdir_lock"), the increment lived in proc_mkdir_data() and
proc_create_mount_point(), and was therefore applied only to
directories.  Moving it into proc_register() to bring it under
proc_subdir_lock dropped the S_ISDIR check.

Thus, move the nlink accounting into pde_subdir_insert() and
pde_erase(), only updating it for directories in both, so the link
count is always changed together with the directory entry itself.

Subject: [PATCH 5026/5214] ovl: use linked upper dentry in copy-up tmpfile
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ovl_copy_up_tmpfile() stores the disconnected O_TMPFILE dentry as the
overlay's upper dentry reference via ovl_inode_update().  vfs_tmpfile()
allocated this dentry via d_alloc(parentpath->dentry, &slash_name), so
d_name is "/" and d_parent is c->workdir.  Local upper filesystems
(ext4, btrfs, xfs, ...) immediately rename it to "#<inum>" via
d_mark_tmpfile() inside their ->tmpfile() op; FUSE and virtiofs do
not, so both fields stay that way.  Neither identifies the destination
directory and filename where ovl_do_link() actually linked the file.

When the upper filesystem implements ->d_revalidate() (e.g. FUSE or
virtiofs), ovl_revalidate_real() calls it with the dentry's parent
inode and a snapshot of d_name.  The server tries to look up "/" inside
c->workdir, fails, and overlayfs reports -ESTALE.

This causes persistent ESTALE errors for any file that was copied up via
the tmpfile path, breaking dpkg, apt, and other tools that do
rename-over-existing on overlayfs with a FUSE/virtiofs upper.

Before commit 6b52243f633e ("ovl: fold copy-up helpers into callers"),
the tmpfile copy-up path used a dedicated helper ovl_link_tmpfile()
that captured the linked destination dentry returned by ovl_do_link():

    err = ovl_do_link(temp, udir, upper);
    ...
    if (!err)
        *newdentry = dget(upper);

and published it via ovl_inode_update(d_inode(c->dentry), newdentry).
The fold inlined ovl_do_link() into ovl_copy_up_tmpfile() but dropped
the dget(upper) capture, and rewrote the publish line as
ovl_inode_update(d_inode(c->dentry), dget(temp)) — where temp is the
disconnected O_TMPFILE dentry.

Fix by keeping a reference to the linked destination dentry after
ovl_do_link() succeeds, and publishing that dentry at the existing
ovl_inode_update() call site.  The non-tmpfile/workdir path continues to
publish the renamed temporary dentry.

Reproducer:
  - Mount overlayfs with virtiofs (or a FUSE fs whose server advertises
    FUSE_TMPFILE) as upper
  - Run: dpkg -i <any .deb>
  - Observe: "error installing new file '...': Stale file handle"

Subject: [PATCH 5027/5214] minix: avoid overflow in bitmap block count
 calculation

minix_check_superblock() uses minix_blocks_needed() to verify that the
on-disk imap and zmap block counts are large enough for the advertised
inode and zone counts.

The helper currently performs DIV_ROUND_UP() in unsigned int arithmetic.
A Minix v3 image can set s_ninodes or s_zones near UINT_MAX so the
addition inside DIV_ROUND_UP() wraps to zero. That makes a zero imap/zmap
block count look valid, after which minix_fill_super() can dereference
s_imap[0] or s_zmap[0] even though no bitmap buffers were allocated.

Impact: mounting a crafted Minix v3 image whose s_ninodes or s_zones is
near UINT_MAX makes minix_check_superblock() accept a zero bitmap-block
count and minix_fill_super() dereference s_imap[0]/s_zmap[0], panicking
the kernel.

The divisor is the bitmap capacity in bits, blocksize * 8, which is
always a power of two: minix_fill_super() obtains the block size through
sb_set_blocksize(), and blk_validate_block_size() rejects any size that
is not a power of two. Use DIV_ROUND_UP_POW2(), which divides before
adding the round-up term and so cannot overflow for a power-of-two
divisor.

Subject: [PATCH 5028/5214] cachefiles: Fix double unlock in nomem_d_alloc
 error path

When start_creating() fails and returns -ENOMEM, it has already
released the parent directory lock in __start_dirop():

    static struct dentry *__start_dirop(...)
    {
        ...
        inode_lock_nested(dir, I_MUTEX_PARENT);
        dentry = lookup_one_qstr_excl(name, parent, lookup_flags);
        if (IS_ERR(dentry))
            inode_unlock(dir);  <-- Lock released on error
        return dentry;
    }

However, the nomem_d_alloc error path in cachefiles_get_directory()
unconditionally calls inode_unlock(d_inode(dir)) again, causing a
double unlock that corrupts the rwsem state.

This is a leftover from commit 7ab96df840e60 which replaced manual
locking with start_creating() but failed to update the nomem_d_alloc
path (while correctly updating mkdir_error and lookup_error paths).

Subject: [PATCH 5030/5214] fat: stop reading directory entries past the
 end-of-directory marker

The FAT specification[1] (FAT Directory Structure -> "DIR_Name[0]") states:

    If DIR_Name[0] == 0x00, then the directory entry is free (same as for
    0xE5), and there are no allocated directory entries after this one
    (all of the DIR_Name[0] bytes in all of the entries after this one
    are also set to 0).

    The special 0 value, rather than the 0xE5 value, indicates to FAT
    file system driver code that the rest of the entries in this
    directory do not need to be examined because they are all free.

Linux did not honour this. fat_get_entry() kept advancing past the 0x00
terminator; if the trailing on-disk slots were not zero-filled (buggy
formatters, read-only media written by other operating systems, on-disk
corruption) the driver surfaced arbitrary bytes as real directory
entries. On a typical affected image, `ls /mnt` returns ~150 bogus
entries with random binary names, multi-gigabyte sizes, dates ranging
from 1980 to 2106, and a flood of -EIO from stat().

Earlier attempts (v1..v3, see [2][3][4]) added `de->name[0] == 0` guards
at each call site. As Hirofumi pointed out on v3, those guards reject
the entry but fat_get_entry() has already advanced *pos past it; the
next readdir() resumes after the marker and walks straight back into
the garbage. His suggestion was to centralise the check.

This patch:

  * Adds fat_get_entry_eod(), a small wrapper around fat_get_entry()
    that returns -1 when name[0] == 0 and seeks *pos to dir->i_size.
    Per spec every slot after the 0x00 marker is also zero, so jumping
    to the end of the directory is correct: subsequent reads return -1
    from fat_bmap() without re-fetching trailing zero slots, and
    callers persisting *pos across invocations (notably readdir's
    ctx->pos) keep reporting end-of-directory on re-entry.

  * Converts the read/search paths to use the new wrapper:
      fat_parse_long(), fat_search_long(), __fat_readdir(),
      and fat_get_short_entry() -- the last covers
      fat_get_dotdot_entry(), fat_dir_empty(), fat_subdirs(),
      fat_scan(), and fat_scan_logstart() transitively.

  * Leaves fat_add_entries() and __fat_remove_entries() on raw
    fat_get_entry(): the write paths legitimately need to operate on
    free/zero slots. fat_add_entries() additionally detects an
    allocated entry past a 0x00 marker (the spec violation that
    produces the garbage) and treats it as filesystem corruption:
    fat_fs_error_ratelimit() is called -- which honours the configured
    errors= mount option (panic / remount-ro / continue) -- and the
    operation returns -EIO so we don't write fresh entries into an
    already-corrupt directory.

Subject: [PATCH 5031/5214] freevxfs: don't BUG() on unknown typed-extent type

vxfs_bmap_typed() handles four typed-extent types and calls BUG() in
its default case, so an on-disk typed extent with any other type value
crashes the kernel. It is reachable from ioctl(FIBMAP) on a regular
file:

  kernel BUG at fs/freevxfs/vxfs_bmap.c:230!
  RIP: vxfs_bmap_typed fs/freevxfs/vxfs_bmap.c:230 [inline]
       vxfs_bmap1+0x128a/0x12d0 fs/freevxfs/vxfs_bmap.c:257

Replace the BUG() with WARN_ON_ONCE() and return 0 -- the value
vxfs_bmap_typed() already returns on failure (and from the DEV4 case
above); vxfs_getblk() maps 0 to -EIO, so the ioctl fails cleanly.

Subject: [PATCH 5032/5214] orangefs: keep the readdir entry size 64-bit in
 fill_from_part()

fill_from_part() computes the size of a directory entry in size_t but
stores it in a __u32. An entry length near U32_MAX wraps it to a small
value, bypasses the bounds check, and is then used to index the entry,
reading far past the directory part -- an out-of-bounds read that oopses
the kernel.

Compute the size as a u64 so it cannot truncate; the bounds check then
rejects the entry. The trailer is supplied by the userspace client.

Subject: [PATCH 5033/5214] bpf: have bpf_real_data_inode() take a struct file

bpf_real_data_inode() must be usable from the bprm_check_security,
mmap_file and file_mprotect hooks for systemd's RestrictFilesystemAccess
BPF LSM program, so have it take a struct file instead of a dentry.

Amir Goldstein <amir73il@gmail.com> suggests:

  While doing so, rename it from bpf_real_inode() to
  bpf_real_data_inode(). For a regular file on a union/overlay
  filesystem it resolves to the underlying inode that hosts the data,
  but for a non-regular file it returns the overlay inode. The new name
  makes the "inode hosting the data" intent explicit and avoids the
  ambiguity of "the real inode backing a file". Document the
  non-regular-file behavior in the kfunc too.

Both the signature change and the rename are safe because the kfunc
landed this cycle and has no released users.

when the log buftarg allocation fails, out_free_rtdev_targ frees the rt
buftarg - releasing rtdev_file - and then falls through to
out_close_rtdev and releases it a second time.

The unwind also leaves mp->m_rtdev_targp and mp->m_ddev_targp pointing
to the freed buftargs. The failed mount continues into
deactivate_locked_super() -> xfs_kill_sb() -> xfs_mount_free(), which
frees them again.

Clear the buftarg pointers once the unwind freed them and clear
rtdev_file once the rt buftarg owns it, so nothing is released twice.

Reachable when a buftarg allocation fails after the data buftarg was
set up: an I/O error in sync_blockdev() or an allocation failure in
xfs_init_buftarg() while mounting with external rt and log devices.

Subject: [PATCH 5035/5214] iomap: guard io_size EOF trim against concurrent
 truncate underflow

iomap: fix zero padding data issue in concurrent append writes
changed ioend accounting so that io_size tracks only valid data
within EOF.  This trims io_size when a writeback range extends
past end_pos:

    ioend->io_size += map_len;
    if (ioend->io_offset + ioend->io_size > end_pos)
        ioend->io_size = end_pos - ioend->io_offset;

However, if end_pos ends up below ioend->io_offset, the subtraction
becomes negative and is stored in size_t io_size, causing an unsigned
wrap to a huge value.  This can happen when writeback continues past
byte-level EOF up to a block-aligned range, or when a concurrent
truncate shrinks the file after end_pos was sampled in
iomap_writeback_handle_eof().

A wrapped io_size can mislead append detection and corrupt
completion-time size handling, since filesystem end_io paths consume
io_size for decisions such as on-disk EOF updates and unwritten/COW
completion ranges.

Fix this by clamping io_size to zero when EOF has moved to or before
the ioend start offset.  This preserves the original intent of trimming
io_size to valid in-EOF data while avoiding the underflow.

Subject: [PATCH 5036/5214] exec: fix off-by-one in binfmt max rewrite depth
 comment

The loop in exec_binprm() permits depth values 0 through 5, up to 5
successive binfmt rewrites (setting bprm->interpreter) until the 6th
one would fail on depth > 5 and return -ELOOP. The comment claimed 4
levels, which was wrong. Adjusting the code to allow only 4 rewrites
would be breaking userland, so fix the comment and not the code.

Reproducer (a chain of shebanged scripts followed by an ELF binary):

    #!/bin/sh

    tmp=$(mktemp -d)
    echo $tmp
    cd $tmp

    mk () { echo $2 > $1; chmod +x $1; }

    for i in $(seq 4); do
    	mk $i "#!$((i + 1))"
    done

    mk 5 '#!/bin/true'
    ./1 &&
    echo '5 binfmt rewrites OK (1 -> 2 -> 3 -> 4 -> 5 -> /bin/true)'

    mk 5 '#!6'
    mk 6 '#!/bin/true'
    ./1 ||
    echo '6 binfmt rewrites KO (1 -> 2 -> 3 -> 4 -> 5 -> 6 -> /bin/true)'

Subject: [PATCH 5037/5214] netfs: Fix decision whether to disallow
 write-streaming due to fscache use

netfs_perform_write() buffers data by writing it into the pagecache for
later writeback.  If the folio it wants to write to isn't present, it uses
"write streaming" in which is will store partial data in a non-uptodate,
but dirty folio.

However, when fscache is in use, this is a potential problem as writes to
the cache have to be aligned to the cache backend's DIO granularity, and so
netfs_perform_write() attempts to suppress write-streaming in such a case,
requiring the folio content to be fetched first unless the entire folio is
going to be overwritten.  This allows the content to be written to the
cache too.

Unfortunately, the test netfs_perform_write() uses isn't correct because it
doesn't take into account the fact that the object lookup is asynchronous
and farmed off to a work queue, so there's a short window in which the
cache is doing a lookup but the test fails because the answer is undefined.

This can be triggered by the generic/464 xfstest, and causes a warning to
be emitted in cachefiles (in code not yet upstream) because it sees a write
that doesn't have its bounds rounded out to DIO alignment.

Fix this by changing the condition to whether FSCACHE_COOKIE_IS_CACHING is
set on a cookie rather than whether the cookie is marked enabled.  Note
that this is really just a hint as to whether we allow write streaming or
not and no other aspects of the cookie or cache object are accessed.

Also apply the same fix to netfs_write_begin().

Subject: [PATCH 5038/5214] netfs: Fix netfs_create_write_req() to handle async
 cache object creation

netfs_create_write_req() will skip caching if the fscache cookie is
disabled, but this is a problem because async cache object creation might
not have got far enough yet that has been enabled - thereby causing the
call to fscache_begin_write_operation() to be skipped.

Fix this by removing the checks on the cookie and delegating this to
fscache_begin_write_operation().

Subject: [PATCH 5043/5214] iov_iter: Fix a memory leak in
 iov_iter_extract_user_pages()

There's a potential memory leak in callers of iov_iter_extract_user_pages()
whereby if a pages array is allocated in function, it isn't freed before
returning of an error or 0.

Now, it's not a leak per se in iov_iter_extract_user_pages() as, if an
array is allocated, it's returned through *pages, so it's incumbent on the
caller to free it.  However, not all callers do.

Fix this by freeing the table and clearing *pages before returning an error
or 0.  Note that iov_iter_extract_pages() and its subfunctions are allowed
to return 0 without returning an array (for instance if the iterator count
is 0).

Subject: [PATCH 5044/5214] iov_iter: Remove unused variable in
 kunit_iov_iter.c

Remove the no longer used variable 'b' from iov_kunit_copy_to_bvec().  The
variable is initialised and incremented, but nothing now makes use of the
value.

Subject: [PATCH 5047/5214] netfs: Replace wb_lock with a bit lock for
 asynchronicity

The netfs_inode::wb_lock mutex is used to prevent multiple simultaneous
writebacks from fighting each other (a writeback thread will write multiple
discontiguous regions within the same request).  The mutex, however, only
serialises the issuing of subrequests; it doesn't serialise the collection
of results, and, in particular, the updating of file size information and
fscache populatedness data.

Unfortunately, the mutex cannot be held around the entire process as it has
to be unlocked in the same thread in which it is locked - and we don't want
to hold up the allocator whilst we complete the writeback.

Fix this by replacing the mutex with a bit flag and a list of lock waiters
so that the lock can be dropped in the collector thread after collection is
complete.

Fix writethrough write to set NETFS_RREQ_OFFLOAD_COLLECTION on the request
so that collection is processed asynchronously rather than only right at
the end - and also so that asynchronous O_SYNC writes get collected at all.

Subject: [PATCH 5049/5214] netfs: Fix writeback error handling

Fix the error handling in writeback_iter() loop.  If an error occurs,
writeback_iter() needs to be called again with *error set to the error so
that it can clean up iteration state.  Further, the current folio needs
unlocking and redirtying.

Subject: [PATCH 5051/5214] netfs: Fix DIO write retry for filesystems without
 a ->prepare_write()

Fix netfs_unbuffered_write() so that it doesn't re-issue a write twice when
the filesystem doesn't have a ->prepare_write().  The resetting of the
iterator and the call to netfs_reissue_write() should just be removed as
almost everything it does is done again when the loop it's in goes back to
the top.

It does, however, still need the IN_PROGRESS flag setting, so that (and the
stat inc) are moved out of the if-statement.

Further, the MADE_PROGRESS flags should be cleared and wreq->transferred
should be updated, so fix those too.

Subject: [PATCH 5052/5214] fhandle: reject detached mounts in
 capable_wrt_mount()

The recent fhandle RCU fix moved the mount namespace capability check
into capable_wrt_mount(), so a non-NULL mnt_namespace survives the
ns_capable() dereference. The helper still assumes the later
READ_ONCE(mount->mnt_ns) must be non-NULL because may_decode_fh()
checked is_mounted() first.

That assumption is not stable. A detached mount from
open_tree(..., OPEN_TREE_CLONE) can be dissolved on fput while
open_by_handle_at() is between those checks, and umount_tree() can
clear mount->mnt_ns. If the helper observes NULL, it dereferences
mnt_ns->user_ns and panics.

Return false when the RCU read observes a detached mount. This keeps
the relaxed permission path conservative: a mount no longer attached
to a namespace cannot authorize open_by_handle_at() access.

Subject: [PATCH 5053/5214] iomap: consolidate bio submission

Add a iomap_bio_submit_read_endio helper factored out of
iomap_bio_submit_read to that all ->submit_read implementations for
iomap_read_ops that use iomap_bio_read_folio_range can shared the
logic.

Right now that logic is mostly trivial, but already has a bug for XFS
because the XFS version is too trivial:  file system integrity validation
needs a workqueue context and thus can't happen from the default iomap
bi_end_io I/O handler.  Unfortunately the iomap refactoring just before
fs integrity landed moved code around here and the call go misplaced,
meaning it never got called.  The PI information still is verified by
the block layer, but the offloading is less efficient (and the future
userspace interface can't get at it).

Subject: [PATCH 5054/5214] fuse: call fuse_send_readpages explicitly from
 fuse_readahead

Move the call to fuse_send_readpages from the iomap ->submit_read method
to the fuse readahead implementation.

fuse_read_folio() does not need to call fuse_send_readpages() because it
always does reads synchronously (the iomap->submit_read method for this
was a no-op since data->ia is always NULL for fuse_read_folio()).

This prepares for an iomap fix that will call ->submit_read after each
iomap.

Subject: [PATCH 5055/5214] iomap: submit read bio after each extent

Currently the iomap buffered read path tries to build up read context
(i.e. bios for the typical block based case) over multiple iomaps as
long as the sector matches.  This does not take into account files
that can map to multiple different devices.  While this could be fixed
by a bdev check in iomap_bio_read_folio_range, the building up of I/O
over iomaps actually was a problem for the not yet merged ext2 iomap
port, as that does want to send out I/O at the end of an indirect
block mapped range.

So instead of adding more checks move over to a model where a bio only
spans a single iomap.  Change ->submit_read to be called after each
iteration so that the bio based users submit the bio after each iomap.
Fuse is unchanged because the previous commit stopped using ->submit_read
for it.

Subject: [PATCH 5056/5214] pkey: Move keytype check from pkey api to handler

The PKEY_VERIFYPROTK ioctl takes data from user-space and verifies the
contained protected key. While checking the integrity of the ioctl
request structure is the responsibility of the generic pkey_api code,
the verification of the contained protected key is the responsibility
of the pkey handler.

The keytype verification (based on the calculated bitsize of the key)
is part of the protected key verification and therefore the
responsibility of the pkey handler (which already verifies
it). Therefore the keytype verification is removed from the generic
pkey_api code.

As the calculation of the key bitsize is currently wrong, the removal
of the keytype check in pkey_api also removes this wrong
calculation. For this reason, the commit is flagged with the Fixes:
tag.

Subject: [PATCH 5057/5214] ASoC: rsnd: adg: make rsnd_adg_clk_control()
 idempotent

rsnd_adg_clk_control() is asymmetric on the disable path: the clkin
clocks are guarded by clkin_rate[], but the "adg" clock is disabled
unconditionally. If an enable attempt fails (for example a clkin
failing to turn on during resume), the error path correctly rolls
everything back, but rsnd_resume() ignores the return value, so the
following system suspend calls rsnd_adg_clk_disable() again and
underflows the "adg" clock enable count:

  adg_0_clks1 already disabled
  WARNING: drivers/clk/clk.c:1188 clk_core_disable+0xa4/0xac
  Call trace:
   clk_core_disable+0xa4/0xac (P)
   clk_disable+0x30/0x4c
   rsnd_adg_clk_control+0x9c/0x2cc
   rsnd_suspend+0x20/0x74
   device_suspend+0x140/0x3ec
   dpm_suspend+0x168/0x270

Track the enable state explicitly and bail out of redundant
enable/disable calls, mirroring what is already done for the per-SSI
clock prepare state. A failed enable leaves the state as disabled, so
the next suspend becomes a no-op and the next resume retries cleanly.

Subject: [PATCH 5058/5214] drm/xe: wedge from the timeout handler only after
 releasing the queue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A kernel job that exhausts its recovery attempts called
xe_device_declare_wedged() directly from guc_exec_queue_timedout_job(),
while the handler still owned the timed-out job and the queue scheduler
(sched = &q->guc->sched, stopped at the top of the handler).

In the default wedged mode (XE_WEDGED_MODE_UPON_CRITICAL_ERROR),
xe_device_declare_wedged() takes the destructive path in
xe_guc_submit_wedge(): guc_submit_reset_prepare(), xe_guc_submit_stop()
- which calls guc_exec_queue_stop() on every queue, including this one -
softreset and pause-abort. That tears submission down, signals the
in-flight fences and restarts the schedulers. This is the correct
behaviour when the wedge originates outside the TDR, but not when the
TDR itself triggers it: every queue should be torn down except the one
the TDR is currently operating on, which it still owns.

Control then returned to the handler, which kept using the now stale job
and scheduler:

  xe_sched_job_set_error(job, err);
  drm_sched_for_each_pending_job(tmp_job, &sched->base, NULL)
          xe_sched_job_set_error(to_xe_sched_job(tmp_job), -ECANCELED);

drm_sched_for_each_pending_job() warns because the scheduler is no
longer stopped (WARN_ON(!drm_sched_is_stopped())) and the iteration then
dereferences a freed job, faulting on the slab poison:

  Oops: general protection fault ... 0x6b6b6b6b6b6b6c3b
  RIP: guc_exec_queue_timedout_job+...

Defer the wedge until the handler has finished operating on the queue,
right before returning DRM_GPU_SCHED_STAT_NO_HANG, so the teardown no
longer races with this handler's use of @q.

Content-Transfer-Encoding: 8bit

The page-table walk framework may pass a NULL *child pointer for
unpopulated entries. xe_pt_zap_ptes_entry() called container_of(*child)
before checking for NULL, then dereferenced the result, causing a crash.

Move the container_of() call after a NULL guard, so the function returns
early instead of proceeding with an invalid pointer. XE_WARN_ON is kept
to help root cause the issue, but we now bail instead of crashing the
driver.

Subject: [PATCH 5062/5214] drm/amdgpu/soc24: reset dGPU if suspend got aborted

For SOC24 ASICs (RDNA4 / Navi 4x dGPUs) re-enabling PM features fails if an
S3 suspend got aborted, the same issue already handled for SOC21 and SOC15:

  commit df3c7dc5c58b ("drm/amdgpu: Reset dGPU if suspend got aborted")
  commit 38e8ca3e4b6d ("amdgpu/soc15: enable asic reset for dGPU in case of suspend abort")

The aborted resume fails with:

  amdgpu: SMU: No response msg_reg: 6 resp_reg: 0
  amdgpu: Failed to enable requested dpm features!
  amdgpu: resume of IP block <smu> failed -62

Apply the same workaround for soc24: detect the aborted-suspend state at
resume via the sign-of-life register and reset the device before re-init.

This is a workaround till a proper solution is finalized.

Subject: [PATCH 5077/5214] drm/amd/pm: fix amdgpu_pm_info power display units

amdgpu_pm_info displayed power sensor readings with the wrong fractional unit.
It treated the low byte of the raw sensor value as the decimal part of watts,
while that field represents milliwatts in the decoded value. As a result,
debugfs could report misleading SoC power when the remainder was not already
a two-digit centiwatt value.

Example with query = 0x00000354:

  raw field        value
  ---------------------
  query >> 8       3 W
  query & 0xff     84 mW
  decoded power    3084 mW

  output           value
  ---------------------
  before           3.84 W
  after            3.08 W

Subject: [PATCH 5078/5214] drm/amd/display: set MSA MISC1 bit 6 when using VSC
 SDP for DCE 11.x

When BT.2020 colorimetry is selected, the driver sends information using
VSC SDP but does not set "ignore MSA colorimetry" bit on older GPUs with
DCE-based IPs. This causes certain sinks to prefer colorimetry
information in DP MSA, resulting in terrible color rendering ("dull"
colors) when HDR is enabled.

This commit wires up the MISC1 bit 6 for GPUs with DCE 11.x based IPs to
correctly configure sinks to ignore colorimetry information in MSA,
resolving the color rendering issue.

Subject: [PATCH 5079/5214] drm/amdgpu: fix division by zero with invalid uvd
 dimensions

When width or height is less than 16, width_in_mb or height_in_mb
becomes 0, leading to fs_in_mb being 0. This causes a division by
zero when calculating num_dpb_buffer in H264 and H264 Perf decode
paths.

Add validation to reject frames with width < 16 or height < 16
before performing any calculations that depend on these values.

V2: Format change - move up all vaiable definitions.
V3: Use warn_once to avoid spam.

Reuse the parameter length returned by
vcn_v4_0_enc_find_ib_param() instead of rereading it from

This avoids a potential TOCTOU issue if the IB contents

Subject: [PATCH 5081/5214] drm/amdgpu/vce: fix integer overflow in image size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix a security vulnerability where malicious VCE command streams
with oversized dimensions (e.g. 65536×65536) cause 32-bit integer
overflow, wrapping the calculated buffer size to 0. This bypasses
validation and allows GPU firmware to perform out-of-bound memory
access.

The fix uses 64-bit arithmetic to detect overflow and rejects
invalid dimensions before they reach the hardware.

V2: remove redundant check
V3: modify max height value
V4: remove size64

The register lists used on DCN42 variants are different. Some reused
codepaths are trying to access registers not used.

[how]

Add DISPCLK_FREQ_CHANGECNTL, HUBPREQ_DEBUG, and HDMISTREAMCLK_CNTL to
the register lists.

Subject: [PATCH 5084/5214] drm/amd/display: Remove DCCG registers not needed
 in DCN42

[why]

Some resources that exist in the DCN block are not needed and shouldn't
be used.

[how]

Remove defines from register lists.

Subject: [PATCH 5085/5214] drm/amd/display: avoid large stack allocation in
 commit_planes_do_stream_update_sequence

The function has two arrays on the stack to hold temporary dsc_optc_config
and dsc_config objects. The combination blows through common stack frame
warning limits in combination with the other local variables:

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:4070:22: error: stack frame size (1352) exceeds limit
      (1280) in 'commit_planes_do_stream_update_sequence' [-Werror,-Wframe-larger-than]

Since neither array is initialized or used outside of the
add_link_update_dsc_config_sequence() function, there is no actual
need to keep each element around.

Replace the arrays with a single instance each to reduce the stack usage
to less than half.

Subject: [PATCH 5086/5214] drm/amdgpu: fix aperture mapping leak
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

amdgpu_pci_remove() calls drm_dev_unplug() before invoking the driver
fini routines. This causes drm_dev_enter() in amdgpu_ttm_fini() to
always return false, so iounmap(aper_base_kaddr) never runs on normal
driver unload, leaving an orphaned entry in the x86 PAT interval tree.

On connected_to_cpu hardware, the aperture is mapped write-back (WB) via
ioremap_cache(). On reload, IP discovery calls memremap(..., MEMREMAP_WC)
over the same range. The WC vs WB conflict causes:

  ioremap error for 0x..., requested 0x1, got 0x0
  amdgpu: discovery failed: -2

Fix by switching to devres-managed mappings so cleanup is guaranteed
regardless of drm_dev_enter() state:

- connected_to_cpu path: devm_memremap(MEMREMAP_WB). For
  IORESOURCE_SYSTEM_RAM ranges this takes the try_ram_remap() shortcut,
  returning __va(offset) from the existing kernel direct map. No new
  ioremap VA or PAT entry is created, so there is nothing to orphan.

- dGPU path: devm_ioremap_wc() registers iounmap() as a devres action,
  guaranteeing cleanup at device_del() time.

Also remove iounmap(aper_base_kaddr) from amdgpu_device_unmap_mmio()
since the mapping is now devres-owned.

Subject: [PATCH 5087/5214] drm/amdkfd: clamp v9 CRIU control stack checkpoint
 copy to BO size

CRIU checkpoint copies the MQD control stack using cp_hqd_cntl_stack_size
from hardware without bounding it to the allocated BO region. If the HW
field is larger than the queue's control stack allocation, memcpy reads
past the BO into adjacent GTT memory and can leak kernel data to userspace.

Store the page-aligned control stack BO size in mqd_manager and clamp
checkpoint copies and reported checkpoint sizes to
min(cp_hqd_cntl_stack_size, mm->ctl_stack_size). Apply the same bound
for multi-XCC v9.4.3 checkpoint layout.

Subject: [PATCH 5090/5214] drm/amd/display: Handle struct
 drm_plane_state.ignore_damage_clips

The mode-setting pipeline can disabled damage clippings for a commit
by setting ignore_damage_clips in struct drm_plane_state. The commit
will then do a full display update.

Test the flag in DCN code and do a full update in DCN code if it has
been set.

Commit 35ed38d58257 ("drm: Allow drivers to indicate the damage helpers
to ignore damage clips") introduced ignore_damage_clips to selectively
ignore damage clipping in certain framebuffer changes. This driver does
not do that, but DRM's damage iterator will soon rely on the flag.
Therefore supporting it here as well make sense for consistency.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When creating an user-queue, the user space
provides a doorbell BO handle and an offset within
the bo to obtain a doorbell.

However current implementation using xa_store_irq()
to store a doorbell, which allows a later queue created
with the same BO and offset parameters to overwrite an
existing queue and doorbell mapping.

This can cause problems like misrouting fence IRQ
processing to a wrong queue, and mislead the cleanup
process of one queue erasing the mapping of another queue.

This commit fixes this issue by replacing xa_store_irq with
xa_insert_irq, which rejects mapping a reserved
doorbell to a newly created queue

Subject: [PATCH 5092/5214] drm/amdgpu: fix resource leak on ACP reset timeout

When ACP soft reset poll times out, original code returns early without cleanup,
leaking MFD child devices, genpd links and all ACP heap allocations.

Replace direct early return with goto out to force run all cleanup logic
regardless of reset success, preserve timeout error code for caller.

Subject: [PATCH 5094/5214] drm/amd/display: use kvzalloc to allocate struct dc

struct dc has grown large over time (most of it the two inlined
dc_scratch_space copies) and now sits close to the page allocator's 4 MiB
contiguous allocation limit. Its actual size is not fixed by the source
alone, it also depends on the compiler and the .config, so it can easily
cross 4 MiB, e.g. with a newer GCC or a config change.

dc_create() allocates it with kzalloc(). Once struct dc exceeds 4 MiB the
request is rounded up to order 11 (8 MiB), which is above MAX_PAGE_ORDER,
so the page allocator warns and returns NULL. dc_create() then fails, DM
init fails and amdgpu probe aborts with -EINVAL:

  WARNING: mm/page_alloc.c:5197 at __alloc_frozen_pages_noprof+0x2f9/0x380
   dc_create+0x38/0x660 [amdgpu]
   amdgpu_dm_init+0x2d9/0x510 [amdgpu]
   dm_hw_init+0x1b/0x90 [amdgpu]
   amdgpu_device_init.cold+0x150d/0x1e13 [amdgpu]
   amdgpu_driver_load_kms+0x19/0x80 [amdgpu]
   amdgpu_pci_probe+0x1e2/0x4c0 [amdgpu]

dc_create() then returns NULL and DM init fails, which aborts the whole
GPU init and makes amdgpu probe fail with -EINVAL ("hw_init of IP block
<dm> failed -22"), leaving the display unusable. The subsequent
amdgpu_irq_put() warnings during teardown are just fallout of unwinding
a half-initialized device.

struct dc is a software-only bookkeeping structure that is never handed
to hardware DMA and is only ever kept as an opaque pointer, so it does
not require physically contiguous memory. Allocate it with kvzalloc()
(and free it with kvfree()) so that the allocator can fall back to
vmalloc() when a contiguous allocation of that size is not available,
which also avoids the MAX_PAGE_ORDER warning entirely.

v2:
 - Rebase to amd-staging-drm-next.

Subject: [PATCH 5095/5214] drm/amd/display: guard against overflow in HDCP
 message dump

[Why]
mod_hdcp_dump_binary_message() computed target_size (a uint32_t) as roughly
byte_size * msg_size and gated the whole write on buf_size >= target_size. A
large msg_size can overflow target_size, wrapping it to a small value that
passes the check while the loop still writes byte_size * msg_size bytes
into buf. All current callers pass small constants so this is not reachable
today, but the unchecked arithmetic should be hardened.

[How]
Drop the overflow-prone target_size precomputation and instead bounds-check the
output position on every iteration, stopping once the next entry would not leave
room for the trailing terminator. This cannot overflow and, for oversized
messages, dumps as much as fits rather than printing nothing.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The "moved" VM state is a bit unfortunately named, because BOs can end
up in this state without being physically moved. While we need to
invalidate every mapping when BOs are physically moved, in some other
cases like PRT binds/unbinds there is no need to refresh mappings except
those affected by the bind.

Full invalidation of all BO mappings manifested as severe regressions in
PRT bind performance, which this patch fixes. The offending patch is
4cdbba5a16aa ("drm/amdgpu: restructure VM state machine v4") in the
amd-staging-drm-next tree, although it has not yet propagated anywhere
else.

Subject: [PATCH 5098/5214] drm/amdgpu/jpeg: fix jpeg_v5_0_1_is_idle detection

jpeg_v5_0_1_is_idle() initializes ret to false and then accumulates ring
idle status using &=. Since false & condition always remains false, the
function can never report the JPEG block as idle.

Initialize ret to true so the function returns true only when all JPEG
rings report RB_JOB_DONE.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For a short moment during alloc/free the userptr BO is not part of his VM,
so bo->vm_bo can be NULL.

Keep a reference to the VM root PD as parent of the userptr BO so that
we can always use that to wait for all submissions of the VM instead of
only the one involving the userptr BO.

Subject: [PATCH 5105/5214] drm/amdkfd: Use kvcalloc to allocate arrays

There were a few instances in kfd_chardev.c of kvzalloc being
used to allocate memory for an array.

Switch those to kvcalloc, which
- is the standard way of allocating a zero-initialized array
- does a check for the mul overflowing

Subject: [PATCH 5106/5214] drm/amdgpu: Fix AMDGPU_GTT_MAX_TRANSFER_SIZE for
 non-4K systems

Running RCCL unit tests on a system with a 64K PAGE_SIZE triggers
the following warning and causes the test to terminate on latest
upstream kernel:

WARNING: drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:1335 at
amdgpu_bo_release_notify+0x1bc/0x280 [amdgpu],
CPU#18: rccl-UnitTests/33151

Call trace:
amdgpu_bo_release_notify
ttm_bo_release
amdgpu_gem_object_free
drm_gem_object_free
amdgpu_bo_unref
amdgpu_bo_create
amdgpu_bo_create_user
amdgpu_gem_object_create
amdgpu_amdkfd_gpuvm_alloc_memory_of_gpu
kfd_ioctl_alloc_memory_of_gpu
kfd_ioctl
sys_ioctl

The warning is triggered because
amdgpu_ttm_next_clear_entity() returns NULL when a clear buffer
operation is requested. This happens because the GART window
allocation for the default_entity, clear_entity and move_entity
fails during initialization.

Commit [1] introduced separate GART windows for the
default_entity, clear_entity and move_entity of each SDMA
instance. Their sizes are derived from
AMDGPU_GTT_MAX_TRANSFER_SIZE, which is currently defined as 1024
pages. This implicitly assumes a 4K PAGE_SIZE, where 1024 pages
correspond to a 4MB transfer. On a 64K PAGE_SIZE system, however,
the same value expands to 64MB.

The default_entity and clear_entity each allocate one
AMDGPU_GTT_MAX_TRANSFER_SIZE GART window, while the move_entity
allocates two such windows. This results in 16MB of GART space
per SDMA instance on a 4K PAGE_SIZE system, but 256MB per SDMA
instance on a 64K PAGE_SIZE system.

On an MI210 system with five SDMA instances and a 512MB GART
aperture, the total GART space required becomes 1.25GB,
exceeding the available GART aperture. Consequently, GART window
allocation fails, amdgpu_ttm_next_clear_entity() returns NULL,
and the above warning is triggered.

Redefine AMDGPU_GTT_MAX_TRANSFER_SIZE in bytes instead of page
units. Where a page count is required, convert it using
PAGE_SHIFT. This preserves the existing 4MB transfer size across
all PAGE_SIZE configurations while keeping GART window
allocations within the available GART aperture.

Subject: [PATCH 5108/5214] drm/amd/pm: fix smu13 power limit range calculation

SMU13 reports SocketPowerLimitAc/Dc as the default power limit, but
MsgLimits.Power may carry a different firmware bound for the same PPT
throttler. Using only the socket limit for both min and max can therefore
expose an incorrect power range.

Keep the socket limit as the default, but derive the range from both values:
use the lower value for the min base and the higher value for the max base
before applying OD percentages. Keep the current limit query independent
from the cap calculation.

Subject: [PATCH 5109/5214] drm/amd/display: detect_link_and_local_sink: DP alt
 mode timeout path leaks prev_sink reference

prev_sink is unconditionally retained via dc_sink_retain at function
  entry, but the DP alt mode timeout path inside SIGNAL_TYPE_DISPLAY_PORT
  returns false without releasing prev_sink. All other return paths in the
  function correctly call dc_sink_release(prev_sink), making this the only
  missing cleanup.

jpeg_v4_0_3_is_idle() initializes ret to false and then accumulates ring
idle status using &=. Since false & condition always remains false, the
function can never report the JPEG block as idle.

Initialize ret to true so the function returns true only when all JPEG
rings report RB_JOB_DONE.

Subject: [PATCH 5115/5214] drm/xe/rtp: Add struct types for RTP tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We currently have a mixture of styles for our RTP tables with respect of
how we define the number of entries:

  * xe_rtp_process_to_sr() expects to receive the number of entries as
    arguments;
  * xe_rtp_process() expects the array to have a sentinel at the end of
    the array;
  * in xe_rtp_test.c, even though xe_rtp_process_to_sr() does not
    require a sentinel value, we need to rely on that technique to be
    able to count xe_rtp_entry_sr entries because simply using
    ARRAY_SIZE() is not possible.

The style used by xe_rtp_process_to_sr() makes it hard to share the
tables with other compilation units (e.g. kunit tests), since the number
of entries is calculated with ARRAY_SIZE(), which is done at compile
time.

Since we use the size of the tables to create some bitmasks, using a
sentinel style doesn't seem great either.

A way to reconcile things into a single style is to have a struct type
that would hold the entries array and the number of entries.  Since we
have xe_rtp_entry and xe_rtp_entry_sr, we would have one type for each.

The advantage of the proposed approach is that now we have a nice way to
share the tables directly to kunit tests with information about their
size.

v6:
    - Removed sentinels that are not needed

v5:
    - Removed added code from conflict resolution issues

v4:
    - Removed conflicts with main branch

v3:
    - No changes

v2:
    - Add compatibility with new xe_rtp_table_sr format for
      "bad-mcr-reg-forced-to-regular" and
      "bad-regular-reg-forced-to-mcr"

Subject: [PATCH 5116/5214] x86,fs/resctrl: Prevent out-of-bounds access while
 offlining CPU when SNC enabled

The architecture updates the cpu_mask in a domain's header to track which
online CPUs are associated with the domain. When this mask becomes empty
the architecture initiates offline of the domain that includes calling
on resctrl fs to offline the domain. If it is a monitoring domain in
which LLC occupancy is tracked resctrl fs forces the limbo handler to
clear all busy RMID state associated with the domain.

The limbo handler always reads the current event value associated with a
busy RMID irrespective of it being checked as part of regular "is it still
busy" check or whether it will be forced released anyway. When reading an
RMID on a system with SNC enabled the "logical RMID" is converted to the
"physical RMID" and this conversion requires the NUMA node ID of the
resctrl monitoring domain that is in turn determined by querying the NUMA
node ID of any CPU belonging to the monitoring domain.

When the monitoring domain is going offline its cpu_mask is empty causing
the NUMA node ID query via cpu_to_node() to be done with "nr_cpu_ids" as
argument resulting in an out-of-bounds access.

Refactor the limbo handler to skip reading the RMID when the RMID will
just be forced to no longer be dirty in the domain anyway. Add a safety
check to the architecture's RMID reader to protect against this scenario.

Subject: [PATCH 5117/5214] accel/amdxdna: Fix use-after-free in debug BO
 command handling

When a debug BO command completes, job->drv_cmd may already have been
freed. Accessing it from aie2_sched_drvcmd_resp_handler() can result in
a use-after-free and memory corruption.

Fix this by introducing reference counting for drv_cmd objects and
transferring ownership to the job while it is in flight. This ensures
that the command remains valid until the completion handler finishes
processing it.

Subject: [PATCH 5121/5214] selftests/mm: fix ksft_process_madv.sh test
 category

ksft_process_madv.sh currently runs run_vmtests.sh with the mmap category.
Update it to run the process_madv category, since ksft_mmap.sh already
runs the mmap category tests.

This avoids running mmap tests twice and ensures that process_madv tests
are run through the kselftest harness.

Subject: [PATCH 5122/5214] mm: shrinker: fix shrinker_info teardown race with
 expansion

expand_shrinker_info() iterates all visible memcgs under shrinker_mutex,
including memcgs that have not finished ->css_online() yet.

Once pn->shrinker_info has been published, teardown must stay serialized
with expand_shrinker_info() until that memcg is either fully online or no
longer visible to iteration.  Today alloc_shrinker_info() breaks that rule
by dropping shrinker_mutex before freeing a partially initialized
shrinker_info array, which may cause the following race:

CPU0                   CPU1
====                   ====

css_create
--> list_add_tail_rcu(&css->sibling, &parent_css->children);
    online_css
    --> mem_cgroup_css_online
        --> alloc_shrinker_info
            --> alloc node0 info
                rcu_assign_pointer(C->node0->shrinker_info, old0)
                alloc node1 info -> FAIL -> goto err
                mutex_unlock(shrinker_mutex)

                       shrinker_alloc()
                       --> shrinker_memcg_alloc
                           --> mutex_lock(shrinker_mutex)
                               expand_shrinker_info
                               --> mem_cgroup_iter see the memcg
                                   expand_one_shrinker_info
                                   --> old0 = C->node0->shrinker_info
                                       memcpy(new->unit, old0->unit, ...);

                free_shrinker_info
                --> kvfree(old0);

                                       /* double free !! */
                                       kvfree_rcu(old0, rcu);

The same problem exists later in mem_cgroup_css_online().  If
alloc_shrinker_info() succeeds but a subsequent objcg allocation fails,
the free_objcg -> free_shrinker_info() unwind path tears down the already
published pn->shrinker_info arrays without shrinker_mutex.  The
expand_one_shrinker_info() can race with that teardown in the same way,
leading to use-after-free or double-free of the old shrinker_info.

Fix this by serializing shrinker_info teardown with shrinker_mutex, and by
keeping alloc_shrinker_info() error cleanup inside the locked section.

Subject: [PATCH 5123/5214] mm: shrinker: fix NULL pointer dereference in
 debugfs

shrinker_debugfs_add() creates both "count" and "scan" debugfs files
unconditionally.

That assumes every shrinker implements both count_objects() and
scan_objects(), which is not guaranteed.  For example, the xen-backend
shrinker sets count_objects() but leaves scan_objects() NULL, so writing
to its scan file calls through a NULL function pointer and panics the
kernel:

BUG: kernel NULL pointer dereference, address: 0000000000000000
RIP: 0010:0x0
Code: Unable to access opcode bytes at 0xffffffffffffffd6.
Call Trace:
 <TASK>

The count path has the same issue in principle if a shrinker omits
count_objects().

To fix it, only create "count" and "scan" debugfs files when the
corresponding callbacks are present.

Subject: [PATCH 5124/5214] mm/damon/sysfs-schemes: fix dir put orders in
 access_pattern_add_dirs()

Patch series "mm/damon/sysfs-schemes: fix wrong directories put orders in
error paths".

Error paths of damon_sysfs_access_pattern_add_dirs() and
damon_sysfs_scheme_add_dirs() functions put references to directories in
wrong orders.  As a result, uninitialized memory dereference and/or
memory leak can happen.  Fix those.


This patch (of 2):

In access_pattern_add_dirs(), error handling path puts references starting
from setup failed directories.  If the failure happpened from the initial
allication in the setup functions, uninitialized memory dereference
happen.  The allocation failures will not commonly happen, but the
consequence is quite bad.  Fix the wrong reference put orders.

The issue was discovered [1] by Sashiko.

Subject: [PATCH 5125/5214] mm/damon/sysfs-schemes: put stats for
 scheme_add_dirs() internal error

damon_sysfs_scheme_add_dirs() setup the tried_regions directory after the
stats directory setup is completed.  When the tried_regions directory
setup is failed, the setup function ensures the reference for the tried
regions directory is released.  Hence the error path should put references
on setup succeeded directory objects, starting from the stats directory.
However, the error path is putting the tried_regions directory instead of
the stats directory.

As a direct result, the stats directory object is leaked.  Worse yet, if
the tried_regions directory setup failed from the initial allocation, the
scheme->tried_regions field remains uninitialized.  The following
kobject_put(&scheme->tried_regions->kobj) call in the error path will
dereference the uninitialized memory.  The setup failures should not be
common.  But once it happens, the consequence is quite bad.

Fix this issue by correctly putting the stats directory instead of the
tried_regions directory.

The issue was discovered [1] by Sashiko.

Subject: [PATCH 5128/5214] mm/damon/ops-common: handle extreme intervals in
 damon_hot_score()

Fix three issues in damon_hot_score() that comes from wrong handling of
extreme (zero or too high) monitoring intervals user setup.

When the user sets sampling interval zero, damon_max_nr_accesses(), which
is called from damon_hot_score(), causes a divide-by-zero.  Needless to
say, it is a problem.

When the user sets the aggregation interval zero, the function returns
zero.  It is wrong, since the real maximum nr_acceses in the setup should
be one.  Worse yet, it can cause another divide-by-zero from its caller,
damon_hot_score(), since it uses damon_max_nr_accesses() return value as a
denominator.

When the user sets the aggregation interval very high, damon_hot_score()
could return a value out of [0, DAMOS_MAX_SCORE] range.  Since the return
value is used as an index to the regions_score_histogram array, which is
DAMOS_MAX_SCORE+1 size, it causes out of bounds array access.

The issues can be relatively easily reproduced like below.  The sysfs
write permission is required, though.

    # ./damo start --damos_action lru_prio --damos_quota_space 100M \
            --damos_quota_interval 1s
    # cd /sys/kernel/mm/damon/admin/kdamonds/0
    # echo 0 > contexts/0/monitoring_attrs/intervals/sample_us
    # echo 0 > contexts/0/monitoring_attrs/intervals/aggr_us

    [...]
    [  131.336089] RIP: 0010:damon_hot_score+0x27/0xd0
    [...]

Fix the divide-by-zero intervals problems by explicitly handling the zero
intervals in damon_max_nr_accesses().  Fix the out-of-bound array access
by applying [0, DAMOS_MAX_SCORE] bounds before returning from

Subject: [PATCH 5129/5214] mm: page_ext: add count limit to page_ext_iter_next
 to prevent invalid PFN access

The page_ext iteration API does not validate if the PFN still belongs to a
valid section while advancing the iterator.  When dynamically adding
memory in the hotplug path, it can lead to a NULL pointer dereference
during page_ext_lookup at the boundary of the last valid section when
iterator count equals __pgcount.

The for_each_page_ext() macro calls page_ext_iter_next() as its loop
increment.  for_each_page_ext() does a "__page_ext =
page_ext_iter_next(&__iter)" at the end.  This causes page_ext_iter_next()
to increment iter->index past __pgcount and call page_ext_lookup(start_pfn
+ __pgcount).  During memory hotplug (online), the PFN at start_pfn +
__pgcount may belong to a section that has not yet been initialized,
causing page_ext_lookup() to trigger a NULL pointer dereference.

Move the iteration boundary enforcement inside the iterator functions, so

Subject: [PATCH 5130/5214] fs/proc: fix KPF_KSM reported for all anonymous
 pages

Reading /proc/kpageflags for any anonymous page returns KPF_KSM set, even
when KSM is not in use.  As a result, tools misclassify all anonymous
pages as KSM merged.

In stable_page_flags(), if the page is anonymous, then use (mapping &
FOLIO_MAPPING_KSM) check to identify if the anonymous page is KSM page.
However, FOLIO_MAPPING_KSM is FOLIO_MAPPING_ANON | FOLIO_MAPPING_ANON_KSM,
(mapping & FOLIO_MAPPING_KSM) check returns true for all anonymous pages.

To fix it, use FOLIO_MAPPING_ANON_KSM instead.

 size for transact_test()

0x1000 (4k) as page size, which is not always correct for architectures
supporting multiple page sizes.

Switch to use the correct page size.  Otherwise ./ksft_pagemap.sh on a
16k-page-size arm64 box fails with

 $ ./ksft_pagemap.sh

Subject: [PATCH 5137/5214] samples/damon/mtier: fail early if address range
 parameters are invalid

The comment on top of `struct damon_region` clearly says that

    For any use case, @ar should be non-zero positive size.

which is now verified in damon_verify_new_region() if the kernel is built
with DAMON_DEBUG_SANITY.

The WARN_ONCE() can be triggered if the mtier sample module is enabled
before node{0,1}_{start,end}_addr have been properly initialized, which is
obviously not good.

 ------------[ cut here ]------------

Note that the same issue can happen if detect_node_addresses is true, and
node 0 or 1 is memoryless.  Fix it together by checking the validity of
parameters right before damon_new_region() and fail early if they're
invalid.

Subject: [PATCH 5138/5214] mm: do file ownership checks with the proper mount
 idmap

Ever since idmapped mounts were introduced, inode ownership checks (for
side-channel protection) in mincore() and madvise(MADV_PAGEOUT) were done
against the nop_mnt_idmap, which completely ignores the file's mount's
idmap.  This results in odd edgecases like:

1) mount/bind-mount with an idmap userA:userB:1
2) userB runs an owner_or_capable() check on file that is owned by userA
on-disk/in-memory, but owned by userB after idmap translation
3) owner_or_capable() mysteriously fails as the correct idmap wasn't supplied

In the case of mincore/madvise MADV_PAGEOUT, this is usually benign,
because file_permission(file, MAY_WRITE) will probably succeed, as it uses
the proper idmap internally, but it does not need to be the case on e.g a
0444 file where even the owner itself doesn't have permissions to write to
it.

Since this is clearly not trivial to get right, introduce a
file_owner_or_capable() that can carry the correct semantics, and switch
the various users in mm to it.

The issue was found by manual code inspection & an off-list discussion
with Jan Kara.

Subject: [PATCH 5139/5214] tools/virtio: add missing compat definitions for
 vhost_net_test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Patch series "tools: Fix tools/virtio test build", v2.

This series fixes build failures hit by:

  make -C tools/virtio test

Patch 1 adds tools/virtio compatibility definitions needed by current
virtio headers when building the tools/virtio tests.  Patch 2 makes
tools/include/linux/overflow.h include stdint.h for SIZE_MAX, which is
used by its size helper functions.

With the series applied, make -C tools/virtio test builds virtio_test,
vringh_test and vhost_net_test successfully.

Tested on x86_64 and arm64 with:

  make -C tools/virtio clean
  make -C tools/virtio test


This patch (of 2):

vhost_net_test builds virtio_ring.c in userspace.

Recent virtio headers pull in helper headers that are not provided by the
tools/virtio compatibility layer, including asm/percpu_types.h,
linux/completion.h, linux/mod_devicetable.h and linux/virtio_features.h.

Add the missing compat definitions and the DMA attribute used by the
current virtio ring code.

Subject: [PATCH 5142/5214] net/mlx5: HWS, fix matcher leak on resize target
 setup failure

hws_bwc_matcher_move() allocates a replacement matcher before setting it
as the resize target. If mlx5hws_matcher_resize_set_target() fails, the
replacement matcher is not attached anywhere and is leaked.

Fix the leak by destroying the replacement matcher before returning from
the resize-target failure path.

The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.

An x86_64 allyesconfig build showed no new warnings. As we do not have a
mlx5 HWS-capable device to test with, no runtime testing was able to be
performed.

Subject: [PATCH 5144/5214] drm/imagination: Fix double call to
 drm_sched_entity_fini()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Call sequence of double call:
pvr_context_destroy
  pvr_context_kill_queues
    pvr_queue_kill
      drm_sched_entity_destroy
        drm_sched_entity_fini // here
  pvr_context_put
    kref_put(..., pvr_context_release)
      pvr_context_destroy_queues
        pvr_queue_destroy
          drm_sched_entity_fini // here

Call to drm_sched_entity_destroy() from pvr_context_kill_queues() calls
drm_sched_entity_flush() + drm_sched_entity_fini().
drm_sched_entity_flush() ensures all pending jobs are completed and
drm_sched_entity_fini() ensures no further submission is allowed as
per expectation from pvr_context_kill_queues(). Double call to
drm_sched_entity_fini() is misuse of the API so keep call only in
pvr_context_create() failure path.

Subject: [PATCH 5145/5214] drm/imagination: Fix returned size for
 DRM_IOCTL_PVR_DEV_QUERY

For a few subtypes of DRM_IOCTL_PVR_DEV_QUERY, driver was overriding
the returned size unconditionally. This would have resulted in
increase of reported size beyond the amount of data returned to
userspace when args->size < size of query structure.

Updated behaviour matches with the description of
drm_pvr_ioctl_dev_query_args.size and written byte length.
None of the structures of DRM_IOCTL_PVR_DEV_QUERY changed after addition,
so change will not break any compatibility with earlier version.

Subject: [PATCH 5146/5214] drm/imagination: Fix user array stride in
 pvr_set_uobj_array()

pvr_set_uobj_array() copies an array of kernel objects to a userspace
array whose element size is described by out->stride. When out->stride
is different from the kernel object size, the slow path advances the
userspace pointer by the kernel object size and the kernel pointer by the
userspace stride.

This reverses the intended layout. For larger userspace strides, later
copies read from the wrong kernel addresses. For smaller userspace
strides, later copies are written at the wrong userspace offsets. The
padding clear is also done only for the first element instead of the
padding area for each element.

Advance the userspace pointer by out->stride and the kernel pointer by
obj_size, and clear per-element padding while the current userspace
pointer is still available.

XE_RTP_TABLE_SR end up containing runtime values (e.g. blit_cctl_val
derived from gt->mocs.uc_index), triggering:

  xe_hw_engine.c:361: error: initializer element is not a compile-time constant
  xe_hw_engine.c:416: error: initializer element is not a compile-time constant

ARRAY_SIZE() cannot be used as a replacement because it expands through
__must_be_array() -> __BUILD_BUG_ON_ZERO_MSG() -> _Static_assert inside
sizeof(struct{}), which clang < 21 also rejects in the same context.

Replace ARRAY_SIZE() with an open-coded sizeof(arr)/sizeof(elem) in
XE_RTP_TABLE_SR and XE_RTP_TABLE to avoid both issues.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

OA registers are dynamically whitelisted (and again dewhitelisted) on OA
stream open/close. Maintaining OA whitelists separately from non-OA
register whitlists simplifies this management of OA register
whitelisting/dewhitelisting.

 save/restore lists
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now we can save OA whitelisting nonpriv registers to register save/restore
lists. OA nonpriv registers are saved to both hwe->oa_sr as well as
hwe->reg_sr.

During probe, resume and gt-reset flows KMD will apply hwe->reg_sr,
ensuring OA registers are de-whitelisted after these events. For
engine-reset, hwe->reg_sr is registered with GuC and GuC will apply these
registers, ensuring OA registers are de-whitelisted after engine resets.

hwe->oa_sr is used for whitelisting or de-whitelisting OA registers during
OA operation, by toggling the 'deny' bit on oa stream open/close.

Subject: [PATCH 5154/5214] drm/xe/oa: (De-)whitelist OA registers on OA stream
 open/release
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Whitelist OA registers on stream open and de-whitelist on stream
close/release. Whitelisting is only done when 'stream->sample' is
true. 'stream->sample' is only true when (a) xe_observation_paranoid is set
to false by system admin, or (b) the process is perfmon_capable(). This
therefore enforces the OA register whitelisting security requirements.

Since multiple OA streams might be open in parallel on a gt, ensure that
proper locking is in place. Also ensure that OA registers are whitelisted
when the first OA stream is open and de-whitelisted after the last OA
stream is closed.

Non-migratable faults that require devmem incorrectly jump to the 'out'
label, which squashes the error code intended to be returned to the
upper layers. Fix this by returning -EACCES instead.

Subject: [PATCH 5157/5214] drm/xe/display: skip FORCE_WC and vm_bound check
 for external dma-bufs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, xe_display_bo_framebuffer_init() unconditionally attempts to
apply XE_BO_FLAG_FORCE_WC to the buffer and rejects the FB creation with
-EINVAL if the BO is already VM_BINDed.

However, for imported dma-bufs (ttm_bo_type_sg), this check doesn't seem
to make much sense since CPU caching policy is entirely controlled by
the exporter. Plus there is no place to set this flag, in the first
place. Also this is not rejected if not yet vm_binded, but that seems
arbitrary since setting or not setting FORCE_WC should a noop either
way, at this stage, and whether it is currently VM_BINDed makes no
difference.

Currently if we run an app and offload rendering to an external dGPU,
like NV or another xe device, the dma-buf passed back to the compositor
(igpu) will be an actual external import from xe pov, and it will be
missing FORCE_WC, and if the compositor side did a VM_BIND before
turning into it into an fb the whole thing gets rejected.

So it looks like we either need to reject outright, no matter what, or
this usecase is valid and we need to loosen the restriction for sg
buffers.  Proposing here to loosen the restriction.

Subject: [PATCH 5158/5214] drm/xe/userptr: Hold notifier_lock for write on
 inject test path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When CONFIG_DRM_XE_USERPTR_INVAL_INJECT=y, xe_pt_svm_userptr_pre_commit()
runs vma_check_userptr() with the svm notifier_lock taken for read. The
test injection causes vma_check_userptr() to call
xe_vma_userptr_force_invalidate(), which feeds into
xe_vma_userptr_do_inval() with drm_gpusvm_ctx.in_notifier=true. That
flag tells drm_gpusvm_unmap_pages() the caller already holds
notifier_lock for write and only asserts the mode. Because the caller
actually holds it for read, the assertion fires:

  WARNING: drivers/gpu/drm/drm_gpusvm.c:1669 at \
           drm_gpusvm_unmap_pages+0xd4/0x130 [drm_gpusvm_helper]

Acquire notifier_lock for write in pre-commit when the inject Kconfig
is enabled, via new helpers xe_pt_svm_userptr_notifier_lock()/_unlock().
Rename xe_svm_assert_held_read() to
xe_svm_assert_held_read_or_inject_write() so it asserts the correct
mode under each build configuration. Production builds
(CONFIG_DRM_XE_USERPTR_INVAL_INJECT=n) keep the existing read-mode
behavior bit-for-bit.

Subject: [PATCH 5159/5214] drm/xe/userptr: Drop bogus static from finish in
 force_invalidate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The local "finish" pointer in xe_vma_userptr_force_invalidate() is
unconditionally written before each read, so the static storage class
serves no purpose. Worse, it makes the variable a process-wide shared
slot: the function's per-VM asserts do not exclude concurrent callers
on different VMs, so two such callers can race on the slot and take
the wrong if (finish) branch.

The function is gated by CONFIG_DRM_XE_USERPTR_INVAL_INJECT
(developer/test option, default n), so production builds are
unaffected.

Drop the static.

 error path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The error path in hw_engine_init() explicitly frees a BO allocated
with xe_managed_bo_create_pin_map() via xe_bo_unpin_map_no_vm().
Since the managed BO already has a devm cleanup action registered,
this causes a double-free when devm unwinds during probe failure.

Remove the explicit free and let devm handle it, consistent with
all other xe_managed_bo_create_pin_map() callers.

Subject: [PATCH 5162/5214] drm/xe: fix NPD in bo_meminfo()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a buffer object is purged, its ttm.resource is set to NULL via the
TTM pipeline gutting flow. However, the BO remains in the client's
object list until userspace explicitly closes the GEM handle. If memory
stats are queried during this time, accessing bo->ttm.resource->mem_type
will result in a NULL pointer dereference.

Fix this by safely skipping purged BOs in bo_meminfo, as they no longer
consume any memory.

User is getting NPD on device resume, and possible theory is that in
bo_move(), if we need to evict something to SYSTEM to save the CCS state,
but the BO is marked as dontneed, this won't trigger a move but will
nuke the pages, leaving us with a NULL bo resource. And the meminfo()
doesn't look ready to handle a NULL resource.

v2 (Sashiko):
 - There could potentially be other cases where we might end up with a
   NULL resource, so make this a general NULL check for now.

Subject: [PATCH 5163/5214] drm/xe/pt: prevent invalid cursor access for purged
 BOs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

During a page table walk for binding, xe_pt_stage_bind() explicitly
skips initializing the xe_res_cursor for purged BOs, treating them
similarly to NULL VMAs by only setting the cursor size.

However, xe_pt_hugepte_possible() and xe_pt_scan_64K() did not check
if the BO was purged before attempting to walk the cursor using
xe_res_dma() and xe_res_next(). Because the cursor was left
uninitialized for purged BOs, this falls through and triggers
warnings like:

  WARNING: drivers/gpu/drm/xe/xe_res_cursor.h:274 at xe_res_next

Fix this by explicitly checking if the BO is purged in both
xe_pt_hugepte_possible() and xe_pt_scan_64K(), returning early just
as we do for NULL VMAs, avoiding the invalid cursor accesses entirely.

As a precaution, also zero-initialize the cursor in xe_pt_stage_bind()
to ensure we don't pass garbage data into the page table walkers
if we ever hit a similar edge case in the future.

Subject: [PATCH 5165/5214] perf/core: Detach event groups during
 remove_on_exec

perf_event_remove_on_exec() removes events by calling
perf_event_exit_event(). For top-level events, this removes the event from
the context with DETACH_EXIT only.

This can leave inconsistent group state when a removed event is a group
leader and the group contains siblings without remove_on_exec. If the group
was active, the surviving siblings can remain active and attached to the
removed leader's sibling list, but are no longer represented by a valid
group leader on the PMU context active lists.

A later close of the removed leader uses DETACH_GROUP and can promote the
still-active siblings from this stale group state. The next schedule-in can
then add an already-linked active_list entry again, corrupting the PMU
context active list.

With DEBUG_LIST enabled, this is caught as a list_add double-add in
merge_sched_in().

Fix this by detaching group relationships when remove_on_exec removes an
event. This preserves the existing task-exit and revoke behavior, while
ensuring surviving siblings are ungrouped before the removed event leaves
the context.

Update the relative CALL emulation and XOL CALL fixup paths to keep the
shadow stack in sync.

Subject: [PATCH 5167/5214] selftests/x86: Add shadow stack uprobe CALL test

Add coverage for entry uprobes installed on CALL instructions while user
shadow stack is enabled. The test puts an entry uprobe on a helper whose
first instruction is a relative CALL, then verifies that the call/return
sequence completes without SIGSEGV.

This catches regressions where x86 uprobe CALL emulation updates the
regular user stack but leaves the CET shadow stack stale.

Subject: [PATCH 5170/5214] s390/monwriter: Reject buffer reuse with different
 data length

When data buffers are reused, e.g. for interval sample records, the
first record determines the data length, and the size of the buffer for
user copy. Current monwriter code does not check if the data length was
changed for subsequent records, which also would never happen for valid
user programs.

However, a malicious user could change the data length, resulting in out
of bounds user copy to the kernel buffer, and memory corruption. By
default, the monwriter misc device is created with root-only permissions,
so practical impact is typically low.

Fix this by checking for changed data length and rejecting such records.

scu_supply is enabled alongside scu and scu_x2 during normal SRC
operation, but rsnd_src_suspend() and rsnd_src_resume() only disable
and re-enable scu and scu_x2. The supply clock is left enabled across
a system suspend and its prepare/enable refcount becomes unbalanced
after a suspend/resume cycle.

Disable scu_supply in rsnd_src_suspend() and re-enable it in
rsnd_src_resume() so the SRC clocks are managed consistently across
system PM transitions.

 dereference in remove_waiter() on self-deadlock""

The commit cited below should not have been merged. It attemted to fix an
existing problem ansd thereby introduced new problems by keeping the
pi_state in state Q_REQUEUE_PI_IN_PROGRESS and leaking it.

Based on the commit description the intention was to handle the case
when task_blocks_on_rt_mutex() returns -EDEADLK and the following
remove_waiter() dereferences the NULL pointer in waiter->task.

That is already handled by Davidlohr in commit 40a25d59e85b3
("locking/rtmutex: Skip remove_waiter() when waiter is not enqueued") and
requires no further acting.

Revert the commit breaking the "waiter == owner" case again.

 SSD

The PNY CS900 1TB SSD (Phison PS3111-S11, DRAM-less) drops off the bus
after entering Device-Initiated Slumber during idle. With the default
med_power_with_dipm policy the link goes down (SStatus 1 SControl 300)
and does not recover, forcing the filesystem read-only. Forcing
max_performance keeps the link stable across prolonged idle.

Add a NOLPM quirk so link power management is disabled for this drive
specifically, leaving it intact for other devices on the host.

Subject: [PATCH 5174/5214] ata: libata-core: Reject an invalid concurrent
 positioning ranges count

ata_dev_config_cpr() takes the number of range descriptors from buf[0]
of the concurrent positioning ranges log (up to 255), which the device
reports independently of the log size in the GPL directory. The count is
then walked at a fixed 32-byte stride in two places with no bound: the
log read here, and the INQUIRY VPD page B9h emitter, which writes one
descriptor per range into the fixed 2048-byte ata_scsi_rbuf. A device
reporting a count larger than its own log overflows the read buffer (up
to 7704 bytes past a 512-byte slab), and a count above 62 overflows the
response buffer on the emit side.

Bound the count once, on probe, against both the log the device returned
and the number of descriptors the VPD B9h response buffer can hold
(ATA_DEV_MAX_CPR, derived from the rbuf size). Reject an out-of-range
count with a warning; this keeps the emitter in bounds with no separate
change there.

Subject: [PATCH 5175/5214] ata: sata_gemini: unwind clocks on IDE pinctrl
 errors

gemini_sata_bridge_init() prepares and enables both SATA PCLKs, then
disables them again while keeping the clocks prepared for later bridge
start and stop operations. If gemini_setup_ide_pins() fails after that,
gemini_sata_probe() returns directly and skips the existing
out_unprep_clk unwind path.

Route the IDE pinctrl failure through out_unprep_clk so the clocks
prepared by gemini_sata_bridge_init() are unprepared before probe
fails.

Subject: [PATCH 5176/5214] ata: pata_pxa: Fix DMA channel leak on probe error

When dmaengine_slave_config() fails, the DMA channel acquired by
dma_request_chan() is not released before returning the error,
leaking the channel reference.

Fix by adding dma_release_channel() in the error path.

The ata_host_activate() error path already correctly releases the
DMA channel.

Subject: [PATCH 5177/5214] ata: libata-scsi: limit simulated SCSI command copy
 to response length

The function ata_scsi_rbuf_fill() is used to copy the response of
emulated SCSI commands from ata_scsi_rbuf to the SCSI command's
scatterlist.

Currently, sg_copy_from_buffer() is called with the size argument
set to ATA_SCSI_RBUF_SIZE (2048 bytes). Since ata_scsi_rbuf is
zeroed out before the simulation actor is invoked, copying the
full buffer size causes the remainder of the SCSI command's
transfer buffer (beyond the actual response length 'len') to be
overwritten with zeroes. This clobbers any pre-existing sentinel
values or data in the caller's buffer tail, even though the
correct residual count is reported via scsi_set_resid().

Fix this by passing the actual response length 'len' as the copy
size to sg_copy_from_buffer(), ensuring that the tail of the
caller's buffer remains untouched. Also, add a defensive check
to ensure that the actor does not return a length exceeding the
static buffer capacity. If this occurs, trigger a WARN_ON(),
fail the command with an aborted command error, and return
immediately without copying any data.

The fix was tested by invoking an SCSI SG_IO INQUIRY on
an ATA disk on vanilla build, and build with the fix. Confirmed
that the input buffer's tail end remains unmodified with the fix.

Subject: [PATCH 5178/5214] mod_devicetable.h: Split into per subsystem headers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:

	$ find drivers -name \*.o -not -name \*.mod.o | wc -l
	21330
	$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
	17038

The result is that even when touching an obscure device id struct most
of the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per subsystem
headers and only including what is really needed reduces the amount of
needed recompilation.

Implement the first step and define each device id struct in a separate
header (together with its associated #defines).

<linux/mod_devicetable.h> is modified to include all the new headers to
continue to provide the same symbols.

Several headers currently include <linux/mod_devicetable.h>, those that
are most lukrative to include only their subsystem headers only are:

	$ git -C source grep -l mod_devicetable.h include/linux | while read h; do echo -n "$h:"; find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l $h | wc -l; done | sort -t: -k2 -n -r | head
	include/linux/of.h:10897
	include/linux/pci.h:7920
	include/linux/acpi.h:7097
	include/linux/i2c.h:5402
	include/linux/spi/spi.h:1897
	include/linux/dmi.h:1643
	include/linux/usb.h:1222
	include/linux/input.h:1205
	include/linux/mdio.h:835
	include/linux/phy.h:733

struct cpu_feature isn't really a device_id struct. That is kept in
<linux/mod_devicetable.h> for now.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver uses several symbols and structs defined in that header. The
header is currently included transitively via

	"vip.h" ->
	<media/v4l2-ctrls.h> ->
	<media/media-request.h> ->
	<media/media-device.h> ->
	<linux/platform_device.h>

which seems to be on the lower end of the scale between random and
reliable.

Subject: [PATCH 5181/5214] driver core: platform: Include header for struct
 platform_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Platform drivers can define an array containing the supported device
variants to be assigned to the struct platform_driver's .id_table.

While a forward declaration of struct platform_device_id is technically
enough to make the driver self-contained, it's reasonable to provide the
(very lightweight) data type definition for that array in
<linux/platform_device.h> to not add that burden to all platform drivers
with an id-table.

Note that currently <linux/device.h> transitively includes
<linux/mod_devicetable.h> that provides struct platform_device_id. But
that include is planned to be replaced by a tighter set of includes that
only define the structures relevant for the stuff in <linux/device.h>.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

<linux/of_platform.h> uses resource_size_t and relies on the transitive
include <linux/mod_devicetable.h> -> <linux/types.h>. It also uses error
constants and thus relying on the include chain
<linux/mod_devicetable.h> -> <linux/uuid.h> -> <linux/string.h> ->
<linux/err.h>.

With the plan to split <linux/mod_devicetable.h> per subsystem and then
only letting of_platform.h include the of-specific bits (which don't
require these two headers), add the needed includes explicitly to keep
the header self-contained.

The subsystem private header i2c-core.h uses several symbols defined in

doesn't pose a problem in practise because all files including

To make this more robust add an include statement for <linux/i2c.h>
making the header self-contained.

 dmi_system_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently <linux/mod_devicetable.h> is included transitively in
int3472.h via

	<linux/clk-provider.h> ->
	<linux/of.h> ->
	<linux/mod_devicetable.h>

However these includes will be tightend such that only the bits relevant
for of will be provided by <linux/of.h>. To ensure that dmi_system_id
stays around, include the respective header explicitly.

Subject: [PATCH 5188/5214] usb: dwc2: Add include defining struct
 pci_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Up to now <linux/acpi.h> includes <linux/mod_devicetable.h> that
provides struct pci_device_id. However <linux/mod_devicetable.h> was
split into per bus headers and <linux/acpi.h> will only include the acpi
related one (and similar for other bus headers).

As struct pci_device_id is used in drivers/usb/dwc2/core.h, add an
include to ensure it's defined also after the includes in <linux/acpi.h>
are tightened.

Subject: [PATCH 5189/5214] ALSA: hda/core: Add include defining struct
 hda_device_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Traditionally all *_device_id were defined in a single header
<linux/mod_devicetable.h>. This was split now with the objective that
only the relevant bits are included. So including <linux/pci.h> won't be
enough to get a definition of (the unrelated to pci) struct
hda_device_id.

Add an explicit include for the header defining struct hda_device_id to
keep working when <linux/pci.h> stops providing this defintion.

Subject: [PATCH 5192/5214] parisc: #include <linux/compiler.h> for unlikely()
 in <asm/ptrace.h>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently <linux/compiler.h> isn't included at all (not even
transitively) in <asm/ptrace.h>.
arch/parisc/kernel/asm-offsets.c just happens to include the following
chain of includes before <asm/ptrace.h>:

	<linux/sched.h>
	-> <asm/processor.h>
	-> <asm/hardware.h>
	-> <linux/mod_devicetable.h>
	-> <linux/uuid.h>
	-> <linux/string.h>
	-> <linux/compiler.h>

. That chain will be broken, because in one of the next commits
<asm/hardware.h> is changed to only include <linux/device-id/parisc.h>
instead of <linux/mod_devicetable.h>. So to ensure
arch/parisc/kernel/asm-offsets.c knows about unlikely() even after that
change, #include <linux/compiler.h> explicitly.

Subject: [PATCH 5193/5214] Replace <linux/mod_devicetable.h> by more specific
 <linux/device-id/*.h> (headers)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

<linux/mod_devicetable.h> is included in a many files:

	$ git grep '<linux/mod_devicetable.h>' ef0c9f75a195 | wc -l
	1598

; some of them are widely used headers. To stop mixing up different and
unrelated driver( type)s let the subsystem headers only use the subset
of the recently split <linux/mod_devicetable.h> that are relevant for
them.

The fallout (I hope) is addressed in the previous commits that handle
sources relying on e.g. <linux/i2c.h> pulling in the full legacy header
and thus providing pci_device_id.

Subject: [PATCH 5194/5214] Replace <linux/mod_devicetable.h> by more specific
 <linux/device-id/*.h> (c files)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Subject: [PATCH 5195/5214] netfs: Fix barriering when walking subrequest list

Fix the barriering used when walking the subrequest list in retry as
there's a possibility of seeing a subreq that's just been added by the
application thread.

Fixes: ee4cdf7ba857 ("netfs: Speed up buffered reading")
Fixes: 288ace2f57c9 ("netfs: New writeback implementation")

Subject: [PATCH 5198/5214] HID: steam: Update documentation

Mark myself as the maintainer, as well as adding myself as an author.

It also makes some minor updates to comments, such as correcly calling the
left menu key view and retroactively renaming the original Steam Controller
as Steam Controller (2015), in preparation for support for the 2026 model.

Subject: [PATCH 5199/5214] HID: steam: Refactor and clean up report parsing

This switches from a parsing style where each button or axis is parsed
individually out of a report using !!(byte & BIT(x)) style. This commit
switches it to a mostly unified approach of defining a list of individual
mappings in an array and passing it to a function that handles all of the
extraction. Theoretically this is more lines, but in practice it results in
(subjectively) cleaner code. Some exceptions still need to be made for
things like handling the lizard mode toggle key, but in general there's a
lot less manual code.

 upstream

SETTING_MOUSE_POINTER_ENABLED was renamed to SETTING_LIZARD_MODE upstream.
SETTING_GYRO_MODE was renamed to SETTING_IMU_MODE in an older commit, but
the associated enum was overlooked.

Subject: [PATCH 5201/5214] HID: steam: Add support for sensor events on the
 Steam Controller (2015)

Sensor support was added for the Steam Deck previously, but Steam
Controller sensor events were never added. This adds that missing support,
bringing Steam Controller support much closer to feature parity with things
like SDL and Steam itself.

Subject: [PATCH 5202/5214] HID: steam: Coalesce rumble packets

The Steam Deck resets the haptic pattern every time it receives a rumble
packet, leading to weird discontinuities or sometimes cutting out entirely.
Instead of overloading the interface, Steam interally rate-limits sending
these packets, so we should too.

Subject: [PATCH 5203/5214] HID: steam: Fully unregister controller when hidraw
 is opened

To avoid conflicts between anything touching the hidraw and the driver we
had previously detached the evdev nodes when the hidraw is opened. However,
this isn't sufficient to avoid FEATURE reports from conflicting, so we
change to fully unregistering the controller internally, leaving only the
hidraw active until it's closed.

This also unifies the unregister and connect callbacks, as now the logic
between these two callbacks is identical.

Subject: [PATCH 5204/5214] HID: steam: Rearrange teardown sequence

This fixes a narrow window during the teardown sequence where callbacks
could still be scheduled during cleanup that would then have a dangling
pointer to the now-freed steam struct.

This also puts work canceling for rumble and mode switch in
steam_unregister, as that shouldn't persist while the client hdev is open.

Subject: [PATCH 5206/5214] HID: steam: Zero-initialize reply in serial lookup

When requesting the serial number from a controller, the function will do
some basic bounds checking to make sure the reply is valid, as well as
capping off the reply with a null byte before copying. However, the error
logging can leak uninitialized memory in some cases. We can simplify and
solve this by just zero-initalizing the reply memory eagerly instead.

Subject: [PATCH 5207/5214] HID: steam: Reject short reads

Steam Controller FEATURE reports encode the size of the message in the
message itself. Previously we were trusting that the size reported matched
the size we actually read, leading to a potential issue with short reads.
Instead, we should actually verify the length of the read.

Subject: [PATCH 5209/5214] HID: steam: Refactor registration

This refactors and simplifies the registration/unregistration flow. Since
we now only perform registration when the client isn't opened anymore, the
logic for handling that can be removed, and the rest of the function
streamlined.

We also remove the previous assumption that we have a serial number to show
we're registered, replacing it with a single purpose boolean.

In a previous refactor the code for unregistering a battery if later
registration steps failed was accidentally left out. As a result, a
lingering power_supply object could get left over after the steam object
was torn down. This is also fixed here.

Subject: [PATCH 5211/5214] HID: steam: Fix wording of connect/disconnect logs

It always said Controller, even on Deck. Since we special-case other
instances of Controller vs. Deck in strings, let's be consistent here too.

Subject: [PATCH 5212/5214] HID: steam: Don't set feature reports when
 disconnecting

When an input device is closed, we set a feature report to reset lizard
mode and IMU mode. However, if the input device is closed because it was
removed, then we will necessarily error out when sending this, resulting in
logged errors. Since an error here is expected, we should just fail
silently.

Subject: [PATCH 5214/5214] HID: steam: Zero out inputs when disabling gamepad
 mode

When gamepad mode is disabled the gamepad input devices will stop receiving
updates. However, in the case where there are buttons still pressed this
will appear as an indefinitely-held button. Instead we should zero out the
inputs to make it look like things are all released. We do the same thing
for gyroscope inputs to make sure it doesn't look like it's endlessly
rotating, but we freeze the accelerometer input since zero isn't a neutral
input on the surface of the Earth.
