HID: wacom: Fix OOB write in wacom_hid_set_device_mode()
wacom_hid_set_device_mode() currently assumes that the HID_DG_INPUTMODE
usage is always located in the first field (field[0]) of the feature report.
However, a device can specify HID_DG_INPUTMODE in a different field.
If HID_DG_INPUTMODE is in a field other than the first one and the first
field has a report_count smaller than the usage_index of HID_DG_INPUTMODE,
this leads to an out-of-bounds write to r->field[0]->value.
Fix this by storing the field index of HID_DG_INPUTMODE in 'struct
hid_data' during feature mapping. In wacom_hid_set_device_mode(), use
this stored field index to access the correct field and add bounds
checks to ensure both the field index and the value index are within
valid ranges before writing.

HID: lenovo: Fix buffer over-read and unaligned access in X12 Tab raw_event handler
In lenovo_raw_event(), the X12 Tab keyboard handler reads a 4-byte
little-endian value from the raw HID report buffer but:
1. The size guard is size >= 3, while the access reads 4 bytes.
A malformed 3-byte report with ID 0x03 would over-read the
buffer by one byte.
2. Casting u8 *data directly to __le32 * can trigger unaligned
access faults on architectures like ARM, MIPS, and SPARC,
because HID input buffers carry no alignment guarantee.
(e.g. uhid payloads start at offset 6 in struct uhid_event,
giving only 2-byte alignment.)
Fix both by tightening the size check to >= 4 and replacing the
open-coded cast + le32_to_cpu() with get_unaligned_le32(), which
handles the LE-to-CPU conversion safely regardless of alignment.

HID: quirks: Add ALWAYS_POLL quirk for SIGMACHIP USB mouse
The SIGMACHIP USB mouse with VID/PID 1c4f:0034 can disconnect and re-enumerate repeatedly after it has been enumerated if its interrupt endpoint is not continuously polled. This was observed with the device reporting itself as "SIGMACHIP Usb Mouse". Keeping the input event device open avoids the disconnects. Add HID_QUIRK_ALWAYS_POLL for this device so the HID core keeps polling it even when there is no userspace input consumer.

HID: u2fzero: free allocated URB on probe errors
u2fzero_fill_in_urb() allocates dev->urb with usb_alloc_urb(), but u2fzero_probe() ignored its return value and only freed the URB from u2fzero_remove(). If LED or hwrng registration fails after the URB allocation, probe returns an error and the driver core does not call .remove(), leaking the URB. A failed URB setup was also allowed to continue probing with an unusable device. Check the URB setup result and add the missing probe-error unwind so the URB is freed before returning from later errors.

HID: pidff: Fix integer overflow in pidff_rescale
Rescaling values close to the max (U16_MAX) temporarily creates values
that exceed the s32 range. This caused value overflow in case when, for
example, a periodic effect phase was higer than 180 degrees. In turn,
rescale function could return values outised of the logical range of the
HID field.
Fix by using 64 bit signed integer to store the value during calculation
but still return only 32 bit integer.

HID: google: hammer: stop hardware on devres action failure
hammer_probe() starts the HID hardware before registering the devres action that stops it. If devm_add_action() fails, probe returns an error with the hardware still started because the cleanup action was never registered and the driver's remove callback is not called after a failed probe. Use devm_add_action_or_reset() so the stop action runs immediately on registration failure while preserving the existing devres-managed cleanup path for later probe failures and remove.

HID: appletb-kbd: run inactivity autodim from workqueues
The autodim code in hid-appletb-kbd takes backlight_device->ops_lock
via backlight_device_set_brightness() -> mutex_lock() from two
different atomic contexts:
* appletb_inactivity_timer() is a struct timer_list callback, so it
runs in softirq context. Every expiry triggers
BUG: sleeping function called from invalid context at kernel/locking/mutex.c:591
Call Trace:
<IRQ>
__might_resched
__mutex_lock
backlight_device_set_brightness
appletb_inactivity_timer
call_timer_fn
run_timer_softirq
* reset_inactivity_timer() is called from appletb_kbd_hid_event() and
appletb_kbd_inp_event(). On real USB hardware these run in
softirq/IRQ context (URB completion and input-event dispatch).
When the Touch Bar has already been dimmed or turned off, the
reset path calls backlight_device_set_brightness() directly to
restore brightness, producing the same warning.
Both call sites hit the same mutex_lock()-from-atomic bug. Fix them
together by moving the blocking work onto the system workqueue:
* Convert the inactivity timer from struct timer_list to
struct delayed_work; the callback (appletb_inactivity_work) now
runs in process context where mutex_lock() is legal.
* Add a dedicated struct work_struct restore_brightness_work and have
reset_inactivity_timer() schedule it instead of calling
backlight_device_set_brightness() directly.
Cancel both works synchronously during driver tear-down alongside the
existing backlight reference drop.
The semantics are unchanged (same delays, same state transitions on
dim, turn-off and user activity); only the execution context of the
sleeping call changes. The timer field and callback are renamed to
match their new type; reset_inactivity_timer() keeps its name because
it is invoked from input event paths that read naturally as "reset
the inactivity timer".

HID: playstation: Clamp num_touch_reports
A device would never lie about the number of touch reports would it?
If it does the loop in dualshock4_parse_report will read off the end of
the touch_reports array, up to about 2 KiB for the maximum number of 256
loop iteraions. The data that is read is emitted via evdev if the
DS4_TOUCH_POINT_INACTIVE bit happens to be set. Protect against this by
clamping the num_touch_reports value provided by the device to the
maximum size of the touch_reports array.

HID: magicmouse: Prevent out-of-bounds (OOB) read during DOUBLE_REPORT_ID
It is currently possible for a malicious or misconfigured USB device to cause an out-of-bounds (OOB) read when submitting reports using DOUBLE_REPORT_ID by specifying a large report length and providing a smaller one. Let's prevent that by comparing the specified report length with the actual size of the data read in from userspace. If the actual data length ends up being smaller than specified, we'll politely warn the user and prevent any further processing.

HID: ft260: validate i2c input report length
Add two checks to ft260_raw_event() to prevent out-of-bounds reads from malicious or malfunctioning devices: First, reject reports shorter than the 2-byte header (report ID + length fields). Without this, even accessing xfer->length on a 1-byte report is an OOB read. Second, validate xfer->length against the actual data capacity of the received HID report. Each I2C data report ID (0xD0 through 0xDE) defines a different report size in the HID descriptor, so the available payload varies per report. A corrupted length field could cause memcpy to read beyond the report buffer.

tracing latency updates for 7.1:
- Add TIMERLAT_ALIGN osnoise option Add a timer alignment option for timerlat that makes it work like the cyclictest -A option. timelat creates threads to test the latency of the kernel. The alignment option will have these threads trigger at the alignment offsets from each other. Instead of having each thread wake up at the exact same time, if the alignment is set to "20" each thread will wake up at 20 microseconds from the previous one. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaeIBaBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qqM8AQCyz4uL1lCLQtJb5thG8V9QFRkYh5F3 +DyuRNoht3ijyAD+K4nZPAu4F09feWuHkssONtSZECKEuN6EhiHE4XX6Pgc= =WYYW -----END PGP SIGNATURE----- Merge tag 'trace-latency-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing latency update from Steven Rostedt: - Add TIMERLAT_ALIGN osnoise option Add a timer alignment option for timerlat that makes it work like the cyclictest -A option. timelat creates threads to test the latency of the kernel.

tracing updates for v7.1:
- Fix printf format warning for bprintf
sunrpc uses a trace_printk() that triggers a printf warning during the
compile. Move the __printf() attribute around for when debugging is not
enabled the warning will go away.
- Remove redundant check for EVENT_FILE_FL_FREED in event_filter_write()
The FREED flag is checked in the call to event_file_file() and then
checked again right afterward, which is unneeded.
- Clean up event_file_file() and event_file_data() helpers
These helper functions played a different role in the past, but now with
eventfs, the READ_ONCE() isn't needed. Simplify the code a bit and also
add a warning to event_file_data() if the file or its data is not present.
- Remove updating file->private_data in tracing open
All access to the file private data is handled by the helper functions,
which do not use file->private_data. Stop updating it on open.
- Show ENUM names in function arguments via BTF in function tracing
When showing the function arguments when func-args option is set for
function tracing, if one of the arguments is found to be an enum, show the
name of the enum instead of its number.
- Add new trace_call__##name() API for tracepoints
Tracepoints are enabled via static_branch() blocks, where when not
enabled, there's only a nop that is in the code where the execution will
just skip over it. When tracing is enabled, the nop is converted to a
direct jump to the tracepoint code. Sometimes more calculations are
required to be performed to update the parameters of the tracepoint. In
this case, trace_##name##_enabled() is called which is a static_branch()
that gets enabled only when the tracepoint is enabled. This allows the
extra calculations to also be skipped by the nop:
if (trace_foo_enabled()) {
x = bar();
trace_foo(x);
}
Where the x=bar() is only performed when foo is enabled. The problem with
this approach is that there's now two static_branch() calls. One for
checking if the tracepoint is enabled, and then again to know if the
tracepoint should be called. The second one is redundant.
Introduce trace_call__foo() that will call the foo() tracepoint directly
without doing a static_branch():
if (trace_foo_enabled()) {
x = bar();
trace_call__foo();
}
- Update various locations to use the new trace_call__##name() API
- Move snapshot code out of trace.c
Cleaning up trace.c to not be a "dump all", move the snapshot code out of
it and into a new trace_snapshot.c file.
- Clean up some "%*.s" to "%*s"
- Allow boot kernel command line options to be called multiple times
Have options like:
ftrace_filter=foo ftrace_filter=bar ftrace_filter=zoo
Equal to:
ftrace_filter=foo,bar,zoo
- Fix ipi_raise event CPU field to be a CPU field
The ipi_raise target_cpus field is defined as a __bitmask(). There is now a
__cpumask() field definition. Update the field to use that.
- Have hist_field_name() use a snprintf() and not a series of strcat()
It's safer to use snprintf() that a series of strcat().
- Fix tracepoint regfunc balancing
A tracepoint can define a "reg" and "unreg" function that gets called
before the tracepoint is enabled, and after it is disabled respectively.
But on error, after the "reg" func is called and the tracepoint is not
enabled, the "unreg" function is not called to tear down what the "reg"
function performed.
- Fix output that shows what histograms are enabled
Event variables are displayed incorrectly in the histogram output.
Instead of "sched.sched_wakeup.$var", it is showing
"$sched.sched_wakeup.var" where the '$' is in the incorrect location.
- Some other simple cleanups.

Arm:
- Add support for tracing in the standalone EL2 hypervisor code, which should help both debugging and performance analysis. This uses the new infrastructure for 'remote' trace buffers that can be exposed by non-kernel entities such as firmware, and which came through the tracing tree. - Add support for GICv5 Per Processor Interrupts (PPIs), as the starting point for supporting the new GIC architecture in KVM. - Finally add support for pKVM protected guests, where pages are unmapped from the host as they are faulted into the guest and can be shared back from the guest using pKVM hypercalls. Protected guests are created using a new machine type identifier. As the elusive guestmem has not yet delivered on its promises, anonymous memory is also supported. This is only a first step towards full isolation from the host; for example, the CPU register state and DMA accesses are not yet isolated. Because this does not really yet bring fully what it promises, it is hidden behind CONFIG_ARM_PKVM_GUEST + 'kvm-arm.mode=protected', and also triggers TAINT_USER when a VM is created. Caveat emptor. - Rework the dreaded user_mem_abort() function to make it more maintainable, reducing the amount of state being exposed to the various helpers and rendering a substantial amount of state immutable. - Expand the Stage-2 page table dumper to support NV shadow page tables on a per-VM basis. - Tidy up the pKVM PSCI proxy code to be slightly less hard to follow. - Fix both SPE and TRBE in non-VHE configurations so that they do not generate spurious, out of context table walks that ultimately lead to very bad HW lockups. - A small set of patches fixing the Stage-2 MMU freeing in error cases. - Tighten-up accepted SMC immediate value to be only #0 for host SMCCC calls. - The usual cleanups and other selftest churn. LoongArch: - Use CSR_CRMD_PLV for kvm_arch_vcpu_in_kernel(). - Add DMSINTC irqchip in kernel support. RISC-V: - Fix steal time shared memory alignment checks - Fix vector context allocation leak - Fix array out-of-bounds in pmu_ctr_read() and pmu_fw_ctr_read_hi() - Fix double-free of sdata in kvm_pmu_clear_snapshot_area() - Fix integer overflow in kvm_pmu_validate_counter_mask() - Fix shift-out-of-bounds in make_xfence_request() - Fix lost write protection on huge pages during dirty logging - Split huge pages during fault handling for dirty logging - Skip CSR restore if VCPU is reloaded on the same core - Implement kvm_arch_has_default_irqchip() for KVM selftests - Factored-out ISA checks into separate sources - Added hideleg to struct kvm_vcpu_config - Factored-out VCPU config into separate sources - Support configuration of per-VM HGATP mode from KVM user space s390: - Support for ESA (31-bit) guests inside nested hypervisors. - Remove restriction on memslot alignment, which is not needed anymore with the new gmap code. - Fix LPSW/E to update the bear (which of course is the breaking event address register). x86: - Shut up various UBSAN warnings on reading module parameter before they were initialized. - Don't zero-allocate page tables that are used for splitting hugepages in the TDP MMU, as KVM is guaranteed to set all SPTEs in the page table and thus write all bytes. - As an optimization, bail early when trying to unsync 4KiB mappings if the target gfn can just be mapped with a 2MiB hugepage. x86 generic: - Copy single-chunk MMIO write values into struct kvm_vcpu (more precisely struct kvm_mmio_fragment) to fix use-after-free stack bugs where KVM would dereference stack pointer after an exit to userspace. - Clean up and comment the emulated MMIO code to try to make it easier to maintain (not necessarily "easy", but "easier"). - Move VMXON+VMXOFF and EFER.SVME toggling out of KVM (not *all* of VMX and SVM enabling) as it is needed for trusted I/O. - Advertise support for AVX512 Bit Matrix Multiply (BMM) instructions - Immediately fail the build if a required #define is missing in one of KVM's headers that is included multiple times. - Reject SET_GUEST_DEBUG with -EBUSY if there's an already injected exception, mostly to prevent syzkaller from abusing the uAPI to trigger WARNs, but also because it can help prevent userspace from unintentionally crashing the VM. - Exempt SMM from CPUID faulting on Intel, as per the spec. - Misc hardening and cleanup changes. x86 (AMD): - Fix and optimize IRQ window inhibit handling for AVIC; make it per-vCPU so that KVM doesn't prematurely re-enable AVIC if multiple vCPUs have to-be-injected IRQs. - Clean up and optimize the OSVW handling, avoiding a bug in which KVM would overwrite state when enabling virtualization on multiple CPUs in parallel. This should not be a problem because OSVW should usually be the same for all CPUs. - Drop a WARN in KVM_MEMORY_ENCRYPT_REG_REGION where KVM complains about a "too large" size based purely on user input. - Clean up and harden the pinning code for KVM_MEMORY_ENCRYPT_REG_REGION. - Disallow synchronizing a VMSA of an already-launched/encrypted vCPU, as doing so for an SNP guest will crash the host due to an RMP violation page fault. - Overhaul KVM's APIs for detecting SEV+ guests so that VM-scoped queries are required to hold kvm->lock, and enforce it by lockdep. Fix various bugs where sev_guest() was not ensured to be stable for the whole duration of a function or ioctl. - Convert a pile of kvm->lock SEV code to guard(). - Play nicer with userspace that does not enable KVM_CAP_EXCEPTION_PAYLOAD, for which KVM needs to set CR2 and DR6 as a response to ioctls such as KVM_GET_VCPU_EVENTS (even if the payload would end up in EXITINFO2 rather than CR2, for example). Only set CR2 and DR6 when consumption of the payload is imminent, but on the other hand force delivery of the payload in all paths where userspace retrieves CR2 or DR6. - Use vcpu->arch.cr2 when updating vmcb12's CR2 on nested #VMEXIT instead of vmcb02->save.cr2. The value is out of sync after a save/restore or after a #PF is injected into L2. - Fix a class of nSVM bugs where some fields written by the CPU are not synchronized from vmcb02 to cached vmcb12 after VMRUN, and so are not up-to-date when saved by KVM_GET_NESTED_STATE. - Fix a class of bugs where the ordering between KVM_SET_NESTED_STATE and KVM_SET_{S}REGS could cause vmcb02 to be incorrectly initialized after save+restore. - Add a variety of missing nSVM consistency checks. - Fix several bugs where KVM failed to correctly update VMCB fields on nested #VMEXIT. - Fix several bugs where KVM failed to correctly synthesize #UD or #GP for SVM-related instructions. - Add support for save+restore of virtualized LBRs (on SVM). - Refactor various helpers and macros to improve clarity and (hopefully) make the code easier to maintain. - Aggressively sanitize fields when copying from vmcb12, to guard against unintentionally allowing L1 to utilize yet-to-be-defined features. - Fix several bugs where KVM botched rAX legality checks when emulating SVM instructions. There are remaining issues in that KVM doesn't handle size prefix overrides for 64-bit guests. - Fail emulation of VMRUN/VMLOAD/VMSAVE if mapping vmcb12 fails instead of somewhat arbitrarily synthesizing #GP (i.e. don't double down on AMD's architectural but sketchy behavior of generating #GP for "unsupported" addresses). - Cache all used vmcb12 fields to further harden against TOCTOU bugs. x86 (Intel): - Drop obsolete branch hint prefixes from the VMX instruction macros. - Use ASM_INPUT_RM() in __vmcs_writel() to coerce clang into using a register input when appropriate. - Code cleanups. guest_memfd: - Don't mark guest_memfd folios as accessed, as guest_memfd doesn't support reclaim, the memory is unevictable, and there is no storage to write back to. LoongArch selftests: - Add KVM PMU test cases s390 selftests: - Enable more memory selftests. x86 selftests: - Add support for Hygon CPUs in KVM selftests. - Fix a bug in the MSR test where it would get false failures on AMD/Hygon CPUs with exactly one of RDPID or RDTSCP. - Add an MADV_COLLAPSE testcase for guest_memfd as a regression test for a bug where the kernel would attempt to collapse guest_memfd folios against KVM's will. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmnftRQUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroPAzwf+NKO4Ktv+7A22ImN0SBl0nlUuulsz vTcw3+hxdRoIw83GdNS+hG5js0wrpMDnbv3t4+VliDNBSSxrBzcSWX2wpilW0Xtw qGo1MWhs2lKPy1NlaRVOwPS6j7uF3AR0TQ1iQLGMedQuCU9WpiKJxyhNXJdbLrt3 8EgFzsvtEsv+jKNRUNDf9+d0j4gZsFyIe+Brhianbw+u3/UCiUClLCdsKPc4+5ZX 08otYXytacGNIf/5Ev1vT4pHkHL0yqKXAtX7LEtaS3+0KrPuLjV4slemivzE9vf5 Evafm5AhA4wpaNMb1ZerhY3T94lsMaJpWxotjR//0Q7C9B59pCQnXCm8mg== =CcE0 -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "Arm: - Add support for tracing in the standalone EL2 hypervisor code, which should help both debugging and performance analysis.

As usual, we enable a number of additional device drivers as loadable modules, to support the added platforms. The largest change this time is for OMAP2/3, which were not that well supported in the generic arm32 defconfig. The Tegra SoC platforms are now enabled by default in Kconfig when ARCH_TEGRA is enabled, which means the defconfig change is done at the same time as the Kconfig change here. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmnhC1IACgkQmmx57+YA GNlH1BAAtiJ53U6+xf83+Eou3trytyXIs3qTw+wQ0mRfXxczeVMV76lRpLcK78iI 8gZg0zMb71kEI4kScOqraewtVGap2ktkz40Nw146q+K+ctj0Qklb54oA+ZS/NVra nE0Cc3PCJkbWTUHQoYpLwiGefFJrahOm7q14JHedmS07Z7BUwzZRaefOp8Jdjafu sEo1gX4lW8f8Yh2HXxf2QuRTcihzGR/kqzYzzl44M4dC5QFRD0ddcUVYgKsfYLkA mp8+mdTcIeNTyOpf9BT0OSXDnt7242lzM+vg59rsp5BY9fxiO1kA1K6gsKb4OCX/ v0R46ZsPdE1NV8BvnZ7eEUUKOhtjzu0hITtVgNg5DsLnRzhuEe/8FEUx1mB2jY56 IwvjchSkUoRX2MPFjSneLSe+u+wZFXaeLNnmkVsIe9CYUThsydZyL8g+l5/xPaTC MMcrI8CehNehZ+ZW5fSt49zXzp80PivdG39xmoKc/UmGIGtPyl7Ual1OEVf+OoxR H8UguX368MK4h5e1KjNZynT/z3obxuOc9e1sqddWx2khDYp0XcGeRcc0nyMREruQ 5Nvyx3KaqRGQBrPUyWBOB9G7ItgIv18aZ+eTtzI5xcgZxvzEmhbwrVecsMjh9B9f 3g3eWOBcV5GbJ1RpN+z5wRXhmQuAXOWWWSCoAUhpm3QpdpNWxo4= =OCxO -----END PGP SIGNATURE----- Merge tag 'soc-defconfig-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC defconfig updates from Arnd Bergmann: "As usual, we enable a number of additional device drivers as loadable modules, to support the added platforms.

soc: drivers for 7.1
The driver updates again are all over the place with many minor fixes
going into platform specific code. The most notable changes are:
- Support for Microchip pic64gx system controllers
- Work on cleaning up devicetree bindings for SoC drivers, and
converting them into the new format
- Lots of smaller changes for Qualcomm SoC drivers, including support
for a number of newly supported chips
- reset controller API cleanups and a new driver for Cix Sky1
- Reworks of the Tegra PMC and CBB drivers, along with a change
to how individual Tegra SoCs get selected in Kconfig and
BPMP firmware driver updates including a refresh of the ABI
header to match the version used by firmware
- STM32 updates to the firewall bus driver and support for
the debug bus through OP-TEE
- SCMI firmware driver improvements for reliability, in particular
for dealing with broken firmware interrupts

soc: dt changes for 7.1
A number of SoC platforms are adding modernized variants of their
already supported chips time, with a total of 12 new SoCs,
and two older SoC getting removed:
- Qualcomm Glymur is a compute SoC using 18 Oryon-2 CPU cores
- Qualcomm Mahua is a variant of Glymur with only 12 CPU cores, but
largely identical.
- Qualcomm Eliza is an embeded platform for mobile phone (SM7750) and IOT
(QC7790S/M) workloads
- Qualcomm IPQ5210 is a wireless networking SoC using Cortex-A53 cores
- Qualcomm apq8084 and ipq806x had only rudimentary support but no
actual products using them, so they are now gone.
- Axis ARTPEC-9 is a follow-up to the ARTPEC-8 embedded SoC, using
the Samsung SoC platform but now with Cortex-A55 cores
- ARM Zena is a virtual platform in FVP using Cortex-A720AE cores, with
additional versions planned to be merged in the future.
- ARM corstone-1000-a320 is a reference platform for IOT, using low-end
Cortex-A320 cores
- Microchip LAN9691 is an updated 64-bit variant of the arm32 lan966x
series of networking SoCs
- Microchip PIC64GX is an embedded RISC-V chip using SIFIVE U54 CPU cores
- Rockchip RV1103B is the low-end 32-bit single-core vision processor
- Renesas RZ/G3L (r9a08g046) is an industrial embedded chip using
Cortex-A55 cores, similar to the G3E and G3S variants we already
supported.
- NXP S32N79 is an automotive SoC using Cortex-A78AE cores, a
significant upgrade from the older S32V and S32G series
These all come with at least one reference board or an initial product
using these, in total there are 67 newly added boards. The ones for
already supported SoCs are:
- Two more Aspeed BMC based boards
- Three older tablets based on 32-bit OMAP4 and Exynos5 SoCs
- One Set-top-box based on Allwinner H6
- 22 additional industrial/embedded boards using 64-bit NXP i.MX8M
or i.MX9 SoCs
- 20 Qualcomm SoC based machines across all possible markets:
workstation, gaming, laptop, phone, networking, reference, ...
- Three more Rockchips rk35xx based boards
- Four variants of the Toradex Verdin using TI AM62
Other notable bits are:
- A cleanup for the 32-bit Tegra paz00 board moved the last
board specific code on Tegra into equivalent dts syntax.
- There continues to be a significant number of fixes for static
checking of dtc syntax, but it feels like this is slowing down,
hopefully getting into a state where most known issues are
addressed
- Additional hardware support for many existing boards across SoC
families, notably Qualcomm, Broadcom, i.MX2, i.MX6, Rockchips,
STM32, Mediatek, Tegra, TI and Microchip

Reviews/patch: 0.92
Reviewed rate: 76%
- The 2 patch series "pid: make sub-init creation retryable" from Oleg
Nesterov increases the robustness of our creation of init in a new
namespace. By clearing away some historical cruft which is no longer
needed. Also some documentation fixups are provided.
- The 2 patch series "selftests/fchmodat2: Error handling and general"
from Mark Brown has a fixup and a cleanup for the fchmodat2() syscall
selftest.
- The 3 patch series "lib: polynomial: Move to math/ and clean up" from
Andy Shevchenko does as advertised.
- The 3 patch series "hung_task: Provide runtime reset interface for
hung task detector" from Aaron Tomlin gives administrators the ability
to zero out /proc/sys/kernel/hung_task_detect_count.
- The 2 patch series "tools/getdelays: use the static UAPI headers from
tools/include/uapi" from Thomas Weißschuh teaches getdelays to use the
in-kernel UAPI headers rather than the system-provided ones.
- The 5 patch series "watchdog/hardlockup: Improvements to hardlockup"
from Mayank Rungta provides several cleanups and fixups to the
hardlockup detector code and its documentation.
- The 2 patch series "lib/bch: fix undefined behavior from signed
left-shifts" from Josh Law provides a couple of small/theoretical fixes
in the bch code.
- The 2 patch series "ocfs2/dlm: fix two bugs in dlm_match_regions()"
from Junrui Luo does what is claims.
- The 27 patch series "cleanup the RAID5 XOR library" from Christoph
Hellwig is a quite far-reaching cleanup to this code. I can't do better
than to quote Christoph:
The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography and
not using the crypto API, with the generic implementations sitting in
include/asm-generic and the arch implementations sitting in an asm/
header in theory. The latter doesn't work for many cases, so
architectures often build the code directly into the core kernel, or
create another module for the architecture code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric Biggers
has done for the CRC and crypto libraries later. After that it
changes to better calling conventions that allow for smarter
architecture implementations (although none is contained here yet),
and uses static_call to avoid indirection function call overhead.
- The 2 patch series "lib/list_sort: Clean up list_sort() scheduling
workarounds" from Kuan-Wei Chiu cleans up this library code by removing
a hacky thing which was added for UBIFS, which UBIFS doesn't actually
need.
- The 5 patch series "Fix bugs in extract_iter_to_sg()" from Christian
Ehrhardt fixes a few bugs in the scatterlist code, adds in-kernel tests
for the now-fixed bugs and fixes a leak in the test itself.
- The 3 patch series "kdump: Enable LUKS-encrypted dump target support
in ARM64 and PowerPC" from Coiby Xu eenables support of the
LUKS-encrypted device dump target on arm64 and powerpc.
- The 4 patch series "ocfs2: consolidate extent list validation into
block read callbacks" from Joseph Qi addresses ocfs2's validation of
extent list fields - cleanup, simplification, robustness. (Kernel test
robot loves mounting corrupted fs images!)
