selftests: net: test extacks in netlink dumps
Test that extacks in dumps work. The test fills up the receive buffer to test both the inline dump (as part of sendmsg()) and delayed one (run during recvmsg()). Use YNL helpers to parse the messages. We need to add the test to YNL file to make sure the right include path are used.

netlink: fix false positive warning in extack during dumps
Commit under fixes extended extack reporting to dumps.
It works under normal conditions, because extack errors are
usually reported during ->start() or the first ->dump(),
it's quite rare that the dump starts okay but fails later.
If the dump does fail later, however, the input skb will
already have the initiating message pulled, so checking
if bad attr falls within skb->data will fail.
Switch the check to using nlh, which is always valid.
syzbot found a way to hit that scenario by filling up
the receive queue. In this case we initiate a dump
but don't call ->dump() until there is read space for
an skb.

net: microchip: vcap: Add typegroup table terminators in kunit tests
VCAP API unit tests fail randomly with errors such as
# vcap_api_iterator_init_test: EXPECTATION FAILED at drivers/net/ethernet/microchip/vcap/vcap_api_kunit.c:387
Expected 134 + 7 == iter.offset, but

Expected 11 == iter.reg_bitpos, but
iter.reg_bitpos == 15 (0xf)
# vcap_api_iterator_init_test: pass:0 fail:1 skip:0 total:1
Comments in the code state that "A typegroup table ends with an all-zero
terminator". Add the missing terminators.
Some of the typegroups did have a terminator of ".offset = 0, .width = 0,
.value = 0,". Replace those terminators with "{ }" (no trailing ',') for
consistency and to excplicitly state "this is a terminator".

net: usb: lan78xx: Fix refcounting and autosuspend on invalid WoL configuration
Validate Wake-on-LAN (WoL) options in `lan78xx_set_wol` before calling
`usb_autopm_get_interface`. This prevents USB autopm refcounting issues
and ensures the adapter can properly enter autosuspend when invalid WoL
options are provided.

tg3: Set coherent DMA mask bits to 31 for BCM57766 chipsets
The hardware on Broadcom 1G chipsets have a known limitation
where they cannot handle DMA addresses that cross over 4GB.
When such an address is encountered, the hardware sets the
address overflow error bit in the DMA status register and
triggers a reset.
However, BCM57766 hardware is setting the overflow bit and
triggering a reset in some cases when there is no actual
underlying address overflow. The hardware team analyzed the
issue and concluded that it is happening when the status
block update has an address with higher (b16 to b31) bits
as 0xffff following a previous update that had lowest bits
as 0xffff.
To work around this bug in the BCM57766 hardware, set the
coherent dma mask from the current 64b to 31b. This will
ensure that upper bits of the status block DMA address are
always at most 0x7fff, thus avoiding the improper overflow
check described above. This work around is intended for only
status block and ring memories and has no effect on TX and
RX buffers as they do not require coherent memory.

net: usb: lan78xx: Fix double free issue with interrupt buffer allocation
In lan78xx_probe(), the buffer `buf` was being freed twice: once
implicitly through `usb_free_urb(dev->urb_intr)` with the
`URB_FREE_BUFFER` flag and again explicitly by `kfree(buf)`. This caused
a double free issue.
To resolve this, reordered `kmalloc()` and `usb_alloc_urb()` calls to
simplify the initialization sequence and removed the redundant
`kfree(buf)`. Now, `buf` is allocated after `usb_alloc_urb()`, ensuring
it is correctly managed by `usb_fill_int_urb()` and freed by
`usb_free_urb()` as intended.

Networking changes for 6.13.
The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core
----
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL
knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read
access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code
--------------------------------------------
- Add small file operations for debugfs, to reduce the struct ops size.
- Refactoring and optimization for the implementation of page_frag API,
This is a preparatory work to consolidate the page_frag
implementation.
Netfilter
---------
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users
the option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent
CI improvements.
BPF
---
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols
---------
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after close,
the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per device
neigh lists.
Driver API
----------
- Introduce a unified interface to configure transmission H/W shaping,
and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling
-----------------
- forwarding: introduce deferred commands, to simplify
the cleanup phase
Drivers
-------
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,

soc: driver updates for 6.12
Nothing particular important in the SoC driver updates, just the usual
improvements to for drivers/soc and a couple of subsystems that don't
fit anywhere else:
- The largest set of updates is for Qualcomm SoC drivers, extending the
set of supported features for additional SoCs in the QSEECOM, LLCC
and socinfo drivers.a
- The ti_sci firmware driver gains support for power managment
- The drivers/reset subsystem sees a rework of the microchip
sparx5 and amlogic reset drivers to support additional chips,
plus a few minor updates on other platforms
- The SCMI firmware interface driver gains support for two protocol
extensions, allowing more flexible use of the shared memory area
and new DT binding properties for configurability.
- Mediatek SoC drivers gain support for power managment on the MT8188
SoC and a new driver for DVFS.
- The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
and a few bugfixes
- The Hisilicon Kunpeng HCCS driver gains support for configuring
lanes through sysfs
Finally, there are cleanups and minor fixes for drivers/soc, drivers/bus,
and drivers/memory, including changing back the .remove_new callback
to .remove, as well as a few other updates for freescale (powerpc)
soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory
controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers

soc: devicetree updates for 6.13
This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device driver
and platform code has already made it in. This is likely the last ARMv5
(!) platform to ever get added, updating the 20+ year old at91/sam9
platform wtih DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number of
A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in older
Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely related
to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and Tablet
chips, still using the older ARMv8.0 cores from RK3328/RK3399 but
with a newer process and other improvements from the RK35xx (otherwise
ARMv8.2) chips. RK3566T and RK3399-S are also added, these are just
lower-cost versions of their normal counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly added
chips above, notably all the Apple phones and tablets. The other new
machines include nine industrial/embedded boards with NXP i.MX6 or i.MX8
SoCs, eight for Rockchips RK35XX and one or two each for Rockchips RV1109,
RK3308, Allwinner A33, Tegra 234, Qualcomm qcs9100/sc8280xp/x1e80100,
TI AM625 and Starfive JH7110.
As usual there are also many newlyad added features in existing boards
as well as cleanups and minor bugfixes.

asm-generic updates for 6.13
These are a number of unrelated cleanups, generally simplifying the
architecture specific header files:
- A series from Al Viro simplifies asm/vga.h, after it turns out that
most of it can be generalized.
- A series from Julian Vetter adds a common version of
memcpy_{to,from}io() and memset_io() and changes most architectures
to use that instead of their own implementation
- A series from Niklas Schnelle concludes his work to make PC
style inb()/outb() optional
- Nicolas Pitre contributes improvements for the generic do_div()
helper
- Christoph Hellwig adds a generic version of page_to_phys()
and phys_to_page(), replacing the slightly different architecture
specific definitions.
- Uwe Kleine-Koenig has a minor cleanup for ioctl definitions

Pull asm-generic updates from Arnd Bergmann:
"These are a number of unrelated cleanups, generally simplifying the
architecture specific header files:
- A series from Al Viro simplifies asm/vga.h, after it turns out that
most of it can be generalized.
- A series from Julian Vetter adds a common version of
memcpy_{to,from}io() and memset_io() and changes most architectures
to use that instead of their own implementation
- A series from Niklas Schnelle concludes his work to make PC style
inb()/outb() optional
- Nicolas Pitre contributes improvements for the generic do_div()
helper
- Christoph Hellwig adds a generic version of page_to_phys() and
phys_to_page(), replacing the slightly different architecture
specific definitions.
- Uwe Kleine-Koenig has a minor cleanup for ioctl definitions"

gpio updates for v6.13-rc1
GPIOLIB core:
- use the new mem_is_zero() instead of memchr_inv(s, 0, n)
- don't store debounce period twice needlessly
- clean-up debugfs handling
- remove leftover comments referring to no longer used spinlocks
- unduplicate some operations like SRCU locks and initializing GPIO descriptors
- constify the sysfs class struct
- use lock guards in GPIO sysfs code
- update GPIO uAPI internal flags all at once atomically for consistency with
other places
- modify the behavior of the sysfs interface by no longer exporting lines that
are named inside the driver code or board files with the sysfs links bearing
the line names as this has for many years been largely unused due to the
prevalence of DT, ACPI and firmware nodes over board files and made the API
inconsistent
- for GPIO interrupt providers: free irqs that are still requested by users
when removing the chip
GPIO uAPI:
- notify user-space about changes to GPIO lines' state (requested, released,
reconfigured) triggered from the kernel as well (until now we'd only do
this for changes triggered from user-space)
- to that end: modify the internal workings of the notification mechanism by
switching to an atomic notifier which allows us to send events from atomic
context
- also to that end store the debounce period in the GPIO descriptor struct
and not in the character device context struct
- while at it, also cover the corner-case of users introducing changes over
sysfs while others watch them via the character device
- don't report GPIO lines requested as interrupts as "used" to user-space as it
can still request them as GPIOs
New drivers:
- add a driver for the GPIO functionality of the MFD Congatec Board Controller
- add a driver for the PolarFire GPIO controller
- add a driver supporting the GPIOs on FTDI FT2232H
Driver improvements:
- use generic device property accessors instead of OF-specific ones across
many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci, ts4900, xilinx, mvebu)
- use devres helpers to simplify error paths and either shrink or entirely
remove the driver's remove() callback (grgpio, amdpt, menz127, max730x,
ftgpio010, 74x164, ljca)
- use helper variables to store the address of pdev->dev and avoid some
line-breaks
- use device_for_each_child_node_scoped() to avoid having to put the fwnode
on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi)
- use a scoped bitmap to simplify the code and drop goto labels in
gpio-aggregator
- drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby, xilinx)
- add support for new models to gpio-aspeed, gpio-rockchip and gpio-dwapb
- clean-up ACPI handling and some other bits in gpio-xgene-sb
- replace deprecated PCI functions in pcie-idio-24 and pci-idio-16
- allow to build davinci and mvebu drivers with COMPILE_TEST=y
- remove dead code in gpio-mb86s7x
- switch back to using platform_driver::remove() (after the conversion to
remove_new()) across the GPIO drivers
- remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop this
deprecated symbol
- convert the gpio-altera driver to no longer pull in the deprecated
legacy-of-mm-gpiochip.h header
- use of_property_present() instead of of_property_read_bool() in gpiolib-of
and gpio-rockchip
- allow to build the tegra186 driver on Tegra234 platforms in Kconfig
Late fixes:
- add a missing return value check after devm_kasprintf() to gpio-grgpio
DT bindings:
- document the ngpios property of gpio-mmio
- add support for a new aspeed model
- fix the example for st,nomadik-gpio
Other:
- kernel doc and comments tweaks
- fix typos in TODO
- reorder headers alphabetically in some drivers
- fix incorrect format specifiers in gpio tools

Pull gpio updates from Bartosz Golaszewski:
"Three new drivers, support for some new models in existing ones and
lots of various tweaks and improvements across the board (switching to
using recommended APIs, code shrink and simplification, etc.).
Also a new feature in the character device uAPI where we now notify
the user-space about changes triggered by in-kernel users as well, not
only when they were done by other user-space agents.

- remove leftover comments referring to no longer used spinlocks
- unduplicate some operations like SRCU locks and initializing GPIO
descriptors
- constify the sysfs class struct
- use lock guards in GPIO sysfs code
- update GPIO uAPI internal flags all at once atomically for
consistency with other places
- modify the behavior of the sysfs interface by no longer exporting
lines that are named inside the driver code or board files with the
sysfs links bearing the line names as this has for many years been
largely unused due to the prevalence of DT, ACPI and firmware nodes
over board files and made the API inconsistent
- for GPIO interrupt providers: free irqs that are still requested by
users when removing the chip
GPIO uAPI:
- notify user-space about changes to GPIO lines' state (requested,
released, reconfigured) triggered from the kernel as well (until
now we'd only do this for changes triggered from user-space)
- to that end: modify the internal workings of the notification
mechanism by switching to an atomic notifier which allows us to
send events from atomic context
- also to that end store the debounce period in the GPIO descriptor
struct and not in the character device context struct
- while at it, also cover the corner-case of users introducing
changes over sysfs while others watch them via the character device
- don't report GPIO lines requested as interrupts as "used" to
user-space as it can still request them as GPIOs
New drivers:
- GPIO part of the MFD Congatec Board Controller
- PolarFire GPIO controller
- GPIOs on FTDI FT2232H
Driver improvements:
- use generic device property accessors instead of OF-specific ones
across many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci,
ts4900, xilinx, mvebu)
- use devres helpers to simplify error paths and either shrink or
entirely remove the driver's remove() callback (grgpio, amdpt,
menz127, max730x, ftgpio010, 74x164, ljca)
- use helper variables to store the address of pdev->dev and avoid
some line-breaks
- use device_for_each_child_node_scoped() to avoid having to put the
fwnode on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi)
- use a scoped bitmap to simplify the code and drop goto labels in
gpio-aggregator
- drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby,
xilinx)
- add support for new models to gpio-aspeed, gpio-rockchip and
gpio-dwapb
- clean-up ACPI handling and some other bits in gpio-xgene-sb
- replace deprecated PCI functions in pcie-idio-24 and pci-idio-16
- allow to build davinci and mvebu drivers with COMPILE_TEST=y
- remove dead code in gpio-mb86s7x
- switch back to using platform_driver::remove() (after the
conversion to remove_new()) across the GPIO drivers
- remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop
this deprecated symbol
- convert the gpio-altera driver to no longer pull in the deprecated
legacy-of-mm-gpiochip.h header
- use of_property_present() instead of of_property_read_bool() in
gpiolib-of and gpio-rockchip
- allow to build the tegra186 driver on Tegra234 platforms in Kconfig
Late fixes:
- add a missing return value check after devm_kasprintf() to
gpio-grgpio
DT bindings:
- document the ngpios property of gpio-mmio
- add support for a new aspeed model
- fix the example for st,nomadik-gpio
Other:
- kernel doc and comments tweaks
- fix typos in TODO
- reorder headers alphabetically in some drivers
- fix incorrect format specifiers in gpio tools"

pwm: Changes for v6.13-rc1
This pull request prominently contains a new abstraction for PWM waveforms that is more expressive that the legacy one. Compared to the old abstraction it contains a duty_offset member instead of polarity. This new abstraction is already used in an ADC driver merged into the iio tree. So I expect you will get a part of this tree also via the iio pull request for 6.13-rc1 (tag pwm/duty_offset-for-6.13-rc1). Otherwise it's the usual collection of fixes, cleanups and dt doc updates. This time around thanks go to Andy Shevchenko, Clark Wang, Conor Dooley, David Lechner, Dimitri Fedrau, Frank Li, Jun Li, Kelvin Zhang, Krzysztof Kozlowski, Nuno Sa, Shen Lichuan and Trevor Gamblin for code contributions, testing and review. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmc7DoAACgkQj4D7WH0S /k5tEgf/QJY8mAPPZR45dDo+GdUnZAaV85sseOezeApjB6kMYXKsKWoDC0uQ9m40 t7zkR8rXCk84rYSg4fGpcWL12v03n8cXmABkJUsqkUkLCcU/pifKzxanC25IWMH1 DGCW8tev4/NSe2ud9kLmFR/p85aioIW47Az3QH096Wv+Y5ij3v5e8PHBIaSiWHlb gfQI1XWerHSbAZexF132zGZOD/TBWb6djAQKACh5KWBPWB54zK3n3ngxoOCSMKSh Li8nfVyy32mPurLfTqaTaAHg7uGrcCGOVhqnXSQiuUayMlV/T7FX/uwfF/X/YKFm iqIPoYeUhLHmHJkHLACtPzUajkTJbg== =3d9l -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm updates from Uwe Kleine-König: "This contains a new abstraction for PWM waveforms that is more expressive that the legacy one.

spi: Updates for v6.13
The only real core work we've got this time around is the completion of
the transition to the new host/target naming for the core APIs, Kconfig
still needs doing but that's a lot less invasive. Otherwise the big
changes are the new drivers that have been added:
- Completion of the conversion to spi_alloc_host()/_target() and
removal of the old naming.
- Cleanups for Rockchip drivers, these brought in a new logging helper
in the driver core for warnings during probe.
- Support for configuration of the word delay via spidev_test.
- Support for AMD HID2 controllers, Apple SPI controller and Realtek
SPI-NAND controllers.

regulator: Updates for v6.13
This was a quite quiet release for regulators on the drivers front, but
we do have two small but useful core improvements:
- Improve handling of cases where DT platforms specify both DT and
init_data based configuration for a single regulator.
- A helper of_regulator_get_optional() to simplify writing generic
bindings for regulator consumers in subsystems.
There's also some YAML conversions for the DT bindings which are a big
part of the diffstat.

kgdb patches for 6.13
A relatively modest collection of changes:
* Adopt kstrtoint() and kstrtol() instead of the simple_strtoXX family
for better error checking of user input.
* Align the print behavour when breakpoints are enabled and disabled by
adopting the current behaviour of breakpoint disable for both.
* Remove some of the (rather odd and user hostile) hex fallbacks and
require kdb users to prefix with 0x instead.
* Tidy up (and fix) control code handling in kdb's keyboard code. This
makes the control code handling at the keyboard behave the same way
as it does via the UART.
* Switch my own entry in MAINTAINERS to my @kernel.org address.

ftrace updates for v6.13:
- Merged tag ftrace-v6.12-rc4 There was a fix to locking in register_ftrace_graph() for shadow stacks that was sent upstream. But this code was also being rewritten, and the locking fix was needed. Merging this fix was required to continue the work. - Restructure the function graph shadow stack to prepare it for use with kretprobes With the goal of merging the shadow stack logic of function graph and kretprobes, some more restructuring of the function shadow stack is required. Move out function graph specific fields from the fgraph infrastructure and store it on the new stack variables that can pass data from the entry callback to the exit callback. Hopefully, with this change, the merge of kretprobes to use fgraph shadow stacks will be ready by the next merge window. - Make shadow stack 4k instead of using PAGE_SIZE. Some architectures have very large PAGE_SIZE values which make its use for shadow stacks waste a lot of memory. - Give shadow stacks its own kmem cache. When function graph is started, every task on the system gets a shadow stack. In the future, shadow stacks may not be 4K in size. Have it have its own kmem cache so that whatever size it becomes will still be efficient in allocations. - Initialize profiler graph ops as it will be needed for new updates to fgraph - Convert to use guard(mutex) for several ftrace and fgraph functions - Add more comments and documentation - Show function return address in function graph tracer Add an option to show the caller of a function at each entry of the function graph tracer, similar to what the function tracer does. - Abstract out ftrace_regs from being used directly like pt_regs ftrace_regs was created to store a partial pt_regs. It holds only the registers and stack information to get to the function arguments and return values. On several archs, it is simply a wrapper around pt_regs. But some users would access ftrace_regs directly to get the pt_regs which will not work on all archs. Make ftrace_regs an abstract structure that requires all access to its fields be through accessor functions. - Show how long it takes to do function code modifications When code modification for function hooks happen, it always had the time recorded in how long it took to do the conversion. But this value was never exported. Recently the code was touched due to new ROX modification handling that caused a large slow down in doing the modifications and had a significant impact on boot times.

Move out function graph specific fields from the fgraph infrastructure and store it on the new stack variables that can pass data from the entry callback to the exit callback. Hopefully, with this change, the merge of kretprobes to use fgraph shadow stacks will be ready by the next merge window. - Make shadow stack 4k instead of using PAGE_SIZE. Some architectures have very large PAGE_SIZE values which make its use for shadow stacks waste a lot of memory. - Give shadow stacks its own kmem cache. When function graph is started, every task on the system gets a shadow stack. In the future, shadow stacks may not be 4K in size. Have it have its own kmem cache so that whatever size it becomes will still be efficient in allocations. - Initialize profiler graph ops as it will be needed for new updates to fgraph - Convert to use guard(mutex) for several ftrace and fgraph functions - Add more comments and documentation - Show function return address in function graph tracer Add an option to show the caller of a function at each entry of the function graph tracer, similar to what the function tracer does. - Abstract out ftrace_regs from being used directly like pt_regs ftrace_regs was created to store a partial pt_regs. It holds only the registers and stack information to get to the function arguments and return values. On several archs, it is simply a wrapper around pt_regs. But some users would access ftrace_regs directly to get the pt_regs which will not work on all archs. Make ftrace_regs an abstract structure that requires all access to its fields be through accessor functions. - Show how long it takes to do function code modifications When code modification for function hooks happen, it always had the time recorded in how long it took to do the conversion. But this value was never exported. Recently the code was touched due to new ROX modification handling that caused a large slow down in doing the modifications and had a significant impact on boot times. Expose the timings in the dyn_ftrace_total_info file. This file was created a while ago to show information about memory usage and such to implement dynamic function tracing.

sched_ext: Change for v6.13
- Improve the default select_cpu() implementation making it topology aware
and handle WAKE_SYNC better.
- set_arg_maybe_null() was used to inform the verifier which ops args could
be NULL in a rather hackish way. Use the new __nullable CFI stub tags
instead.
- On Sapphire Rapids multi-socket systems, a BPF scheduler, by hammering on
the same queue across sockets, could live-lock the system to the point
where the system couldn't make reasonable forward progress. This could
lead to soft-lockup triggered resets or stalling out bypass mode switch
and thus BPF scheduler ejection for tens of minutes if not hours. After
trying a number of mitigations, the following set worked reliably:
- Injecting artificial cpu_relax() loops in two places while sched_ext is
trying to turn on the bypass mode.
- Triggering scheduler ejection when soft-lockup detection is imminent (a
quarter of threshold left).
While not the prettiest, the impact both in terms of code complexity and
overhead is minimal.
- A common complaint on the API is the overuse of the word "dispatch" and
the confusion around "consume". This is due to how the dispatch queues
became more generic over time. Rename the affected kfuncs for clarity.
Thanks to BPF's compatibility features, this change can be made in a way
that's both forward and backward compatible. The compatibility code will
be dropped in a few releases.
- Pull sched_ext/for-6.12-fixes to receive a prerequisite change. Other misc
changes.

A rather large update for timekeeping and timers:
- The final step to get rid of auto-rearming posix-timers
posix-timers are currently auto-rearmed by the kernel when the signal
of the timer is ignored so that the timer signal can be delivered once
the corresponding signal is unignored.
This requires to throttle the timer to prevent a DoS by small intervals
and keeps the system pointlessly out of low power states for no value.
This is a long standing non-trivial problem due to the lock order of
posix-timer lock and the sighand lock along with life time issues as
the timer and the sigqueue have different life time rules.
Cure this by:
* Embedding the sigqueue into the timer struct to have the same life
time rules. Aside of that this also avoids the lookup of the timer
in the signal delivery and rearm path as it's just a always valid
container_of() now.
* Queuing ignored timer signals onto a seperate ignored list.
* Moving queued timer signals onto the ignored list when the signal is
switched to SIG_IGN before it could be delivered.
* Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal delivery
code to rearm the timer.
This also required to consolidate the signal delivery rules so they are
consistent across all situations. With that all self test scenarios
finally succeed.
- Core infrastructure for VFS multigrain timestamping
This is required to allow the kernel to use coarse grained time stamps
by default and switch to fine grained time stamps when inode attributes
are actively observed via getattr().
These changes have been provided to the VFS tree as well, so that the
VFS specific infrastructure could be built on top.
- Cleanup and consolidation of the sleep() infrastructure
* Move all sleep and timeout functions into one file
* Rework udelay() and ndelay() into proper documented inline functions
and replace the hardcoded magic numbers by proper defines.
* Rework the fsleep() implementation to take the reality of the timer
wheel granularity on different HZ values into account. Right now the
boundaries are hard coded time ranges which fail to provide the
requested accuracy on different HZ settings.
* Update documentation for all sleep/timeout related functions and fix
up stale documentation links all over the place
* Fixup a few usage sites
- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP clocks
A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as that's
the clock which drives the timekeeping adjustments via the various user
space daemons through adjtimex(2).
The non TAI based clock domains are accessible via the file descriptor
based posix clocks, but their usability is very limited. They can't be
accessed fast as they always go all the way out to the hardware and
they cannot be utilized in the kernel itself.
As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.
The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the kernel
provides access to clock MONOTONIC, REALTIME etc.
Instead of creating a duplicated infrastructure this rework converts
timekeeping and adjtimex(2) into generic functionality which operates
on pointers to data structures instead of using static variables.
This allows to provide time accessors and adjtimex(2) functionality for
the independent PTP clocks in a subsequent step.
- Consolidate hrtimer initialization
hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.
That's an extra unnecessary step and makes Rust support less straight
forward than it should be.
Provide a new set of hrtimer_setup*() functions and convert the core
code and a few usage sites of the less frequently used interfaces over.
The bulk of the htimer_init() to hrtimer_setup() conversion is already
prepared and scheduled for the next merge window.
- Drivers:
* Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.

Pull timer updates from Thomas Gleixner:
"A rather large update for timekeeping and timers:
- The final step to get rid of auto-rearming posix-timers
posix-timers are currently auto-rearmed by the kernel when the
signal of the timer is ignored so that the timer signal can be
delivered once the corresponding signal is unignored.
This requires to throttle the timer to prevent a DoS by small
intervals and keeps the system pointlessly out of low power states
for no value. This is a long standing non-trivial problem due to
the lock order of posix-timer lock and the sighand lock along with
life time issues as the timer and the sigqueue have different life
time rules.
Cure this by:
- Embedding the sigqueue into the timer struct to have the same
life time rules. Aside of that this also avoids the lookup of
the timer in the signal delivery and rearm path as it's just a
always valid container_of() now.
- Queuing ignored timer signals onto a seperate ignored list.
- Moving queued timer signals onto the ignored list when the
signal is switched to SIG_IGN before it could be delivered.
- Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal
delivery code to rearm the timer.
This also required to consolidate the signal delivery rules so they
are consistent across all situations. With that all self test
scenarios finally succeed.
- Core infrastructure for VFS multigrain timestamping
This is required to allow the kernel to use coarse grained time
stamps by default and switch to fine grained time stamps when inode
attributes are actively observed via getattr().
These changes have been provided to the VFS tree as well, so that
the VFS specific infrastructure could be built on top.
- Cleanup and consolidation of the sleep() infrastructure
- Move all sleep and timeout functions into one file
- Rework udelay() and ndelay() into proper documented inline
functions and replace the hardcoded magic numbers by proper
defines.
- Rework the fsleep() implementation to take the reality of the
timer wheel granularity on different HZ values into account.
Right now the boundaries are hard coded time ranges which fail
to provide the requested accuracy on different HZ settings.
- Update documentation for all sleep/timeout related functions
and fix up stale documentation links all over the place
- Fixup a few usage sites
- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP
clocks
A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as
that's the clock which drives the timekeeping adjustments via the
various user space daemons through adjtimex(2).
The non TAI based clock domains are accessible via the file
descriptor based posix clocks, but their usability is very limited.
They can't be accessed fast as they always go all the way out to
the hardware and they cannot be utilized in the kernel itself.
As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.
The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the
kernel provides access to clock MONOTONIC, REALTIME etc.
Instead of creating a duplicated infrastructure this rework
converts timekeeping and adjtimex(2) into generic functionality
which operates on pointers to data structures instead of using
static variables.
This allows to provide time accessors and adjtimex(2) functionality
for the independent PTP clocks in a subsequent step.
- Consolidate hrtimer initialization
hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.
That's an extra unnecessary step and makes Rust support less
straight forward than it should be.
Provide a new set of hrtimer_setup*() functions and convert the
core code and a few usage sites of the less frequently used
interfaces over.
The bulk of the htimer_init() to hrtimer_setup() conversion is
already prepared and scheduled for the next merge window.
- Drivers:
- Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.
Otherwise CPUs on different clusters use their cluster specific
clocksource which is not guaranteed to be synchronized with
other clusters.

First step of consolidating the VDSO data page handling:
The VDSO data page handling is architecture specific for historical
reasons, but there is no real technical reason to do so.
Aside of that VDSO data has become a dump ground for various mechanisms
and fail to provide a clear separation of the functionalities.
Clean this up by:
* consolidating the VDSO page data by getting rid of architecture
specific warts especially in x86 and PowerPC.
* removing the last includes of header files which are pulling in other
headers outside of the VDSO namespace.
* seperating timekeeping and other VDSO data accordingly.
Further consolidation of the VDSO page handling is done in subsequent
changes scheduled for the next merge window.
This also lays the ground for expanding the VDSO time getters for
independent PTP clocks in a generic way without making every architecture
add support seperately.

A set of updates for the interrupt subsystem:
- Tree wide:
* Make nr_irqs static to the core code and provide accessor functions
to remove existing and prevent future aliasing problems with local
variables or function arguments of the same name.
- Core code:
* Prevent freeing an interrupt in the devres code which is not managed
by devres in the first place.
* Use seq_put_decimal_ull_width() for decimal values output in
/proc/interrupts which increases performance significantly as it
avoids parsing the format strings over and over.
* Optimize raising the timer and hrtimer soft interrupts by using the
'set bit only' variants instead of the combined version which checks
whether ksoftirqd should be woken up. The latter is a pointless
exercise as both soft interrupts are raised in the context of the
timer interrupt and therefore never wake up ksoftirqd.
* Delegate timer/hrtimer soft interrupt processing to a dedicated thread
on RT.
Timer and hrtimer soft interrupts are always processed in ksoftirqd
on RT enabled kernels. This can lead to high latencies when other
soft interrupts are delegated to ksoftirqd as well.
The separate thread allows to run them seperately under a RT
scheduling policy to reduce the latency overhead.
- Drivers:
* New drivers or extensions of existing drivers to support Renesas
RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt
chips
* Support for multi-cluster GICs on MIPS.
MIPS CPUs can come with multiple CPU clusters, where each CPU cluster
has its own GIC (Generic Interrupt Controller). This requires to
access the GIC of a remote cluster through a redirect register block.
This is encapsulated into a set of helper functions to keep the
complexity out of the actual code paths which handle the GIC details.
* Support for encrypted guests in the ARM GICV3 ITS driver
The ITS page needs to be shared with the hypervisor and therefore
must be decrypted.
* Small cleanups and fixes all over the place

A set of changes for debugobjects:
- Prevent destroying the kmem_cache on early failure.
Destroying a kmem_cache requires work queues to be set up, but in the
early failure case they are not yet initializated. So rather leak the
cache instead of triggering a BUG.
- Reduce parallel pool fill attempts.
Refilling the object pool requires to take the global pool lock, which
causes a massive performance issue when a large number of CPUs attempt
to refill concurrently. It turns out that it's sufficient to let one
CPU handle the refill from the to free list and in case there are not
enough objects on it to allocate new objects from the kmem cache.
This also splits the free list handling from the actual allocation path
as that yields better results on RT where allocation is restricted to
preemptible code paths. The refill from free list has no such
restrictions.
- Consolidate the global and the per CPU pools to use the same data
structure, so all helper functions can be shared.
- Simplify the object allocation/free logic.
The allocation/free logic is an incomprehensible maze, which tries to
utilize the to free list and the global pool in the best way. This all
can be simplified into a straight forward comprehensible code flow.
- Convert the allocation/free mechanism to batch mode.
Transferring objects from the global pool to the per CPU pools or vice
versa is done by walking the hlist and moving object by object. That
not only increases the pool lock held time, it also dirties up to 17
cache lines.
This can be avoided by storing the pointer to the first object in a
batch of 16 objects in the objects themself and propagate it through
the batch when an object is enqueued into a pool or to a temporary
hlist head on allocation.
This allows to move batches of objects with at max four cache lines
dirtied and reduces the pool lock held time and therefore contention
significantly.
- Improve the object reusage
The current implementation is too agressively freeing unused objects,
which is counterproductive on bursty workloads like a kernel compile.
Address this by:
* increasing the per CPU pool size
* refilling the per CPU pool from the to be freed pool when the per
CPU pool emptied a batch
* keeping track of object usage with a exponentially wheighted
moving average which prevents the work queue callback to free
objects prematuraly.
This combined reduces the allocation/free rate for a full kernel
compile significantly:
kmem_cache_alloc() kmem_cache_free()
Baseline: 380k 330k
Improved: 170k 117k
- A few cleanups and a more cache line friendly layout of debug
information on top.
