Newer model R3* Topre Realforce keyboards share an issue with their older
R2 cousins where a report descriptor fixup is needed in order for n-key
rollover to work correctly, otherwise only 6-key rollover is available.
This patch adds some new hardware IDs for the R3S 87-key keyboard and
makes amendments to the existing hid-topre driver in order to change the
correct byte in the new model.

When lizard mode is disabled, there were two issues:
1. Switching between gamepad mode and desktop mode still functioned, even
though desktop mode did not. This lead to the ability to "break" gamepad mode
by holding down the Options key even while lizard mode is disabled
2. If you were in desktop mode when lizard mode is disabled, you would
immediately enter this faulty mode.
This patch properly disables the ability to switch between gamepad mode and the
faulty desktop mode by holding the Options key, as well as effectively removing
the faulty mode by bypassing the early returns if lizard mode is disabled.

The HP 5MP Camera (USB ID 0408:5473) reports a HID sensor interface that

In drivers/hid/, most drivers depend on CONFIG_HID, while a couple of the
drivers in subdirectories instead depend on CONFIG_HID_SUPPORT and use
'select HID'. With the newly added INTEL_THC_HID, this causes a build
warning for a circular dependency:
WARNING: unmet direct dependencies detected for HID

It's better to be consistent and always use 'depends on HID' for HID
drivers. The notable exception here is USB_KBD/USB_MOUSE, which are
alternative implementations that do not depend on the HID subsystem.
Do this by extending the "if HID" section below, which means that a few
of the duplicate "depends on HID" and "depends on INPUT" statements
can be removed in the process.

- the link failure still exists with CONFIG_ACPI_PLATFORM_PROFILE=m
when hid-lenovo is built-in
- There is no way to manually enable CONFIG_ACPI_PLATFORM_PROFILE, as
it is intended to be selected by its users.
Remove the broken #if check again and instead select the symbol like

The ISH driver performs a clock sync with the firmware once at system
startup and then every 20 seconds. If a firmware reset occurs right
after a clock sync, the driver would wait 20 seconds before performing
another clock sync with the firmware. This is particularly problematic
with the introduction of the "load firmware from host" feature, where
the driver performs a clock sync with the bootloader and then has to
wait 20 seconds before syncing with the main firmware.
This patch clears prev_sync immediately upon receiving an IPC reset,
so that the main firmware and driver will perform a clock sync
immediately after completing the IPC handshake.

The timestamps in the Firmware log and HID sensor samples are incorrect.
They show 1970-01-01 because the current IPC driver only uses the first
8 bytes of bootup time when synchronizing time with the firmware. The
firmware converts the bootup time to UTC time, which results in the
display of 1970-01-01.
In write_ipc_from_queue(), when sending the MNG_SYNC_FW_CLOCK message,
the clock is updated according to the definition of ipc_time_update_msg.
However, in _ish_sync_fw_clock(), the message length is specified as the
size of uint64_t when building the doorbell. As a result, the firmware
only receives the first 8 bytes of struct ipc_time_update_msg.
This patch corrects the length in the doorbell to ensure the entire
ipc_time_update_msg is sent, fixing the timestamp issue.

Core:
- list-based mechanisms for handling auto-detected and userspace created
clients are replaced with a flag-based approach. The resulting code is
much simpler as well as the locking.
- i2c clients now get a default debugfs dir managed by the I2C core.
Drivers don't have to maintain their own directory anymore.
Drivers:
- xiic gains atomic_transfer support
- imx-lpi2c gains DMA and target mode support
- riic gets a collection of cleanups
- npcm gets a better timeout handling and more precise frequency setups
- davinci loses the unused platform_data
The rest is regular driver updates and improvements.
AT24:

This is a fairly quiet release for the most part, though we do have one
really nice improvement in the spi-mem framework which will improve
performance for flash devices especially when built on by changes in the
MTD subsystem which are also due to be sent this merge window. There's
also been some substantial work on some of the drivers, highlights
include:
- Support for per-operation bus frequency in the spi-mem framework,
meaning speeds are no longer limited by the slowest operation.
- ACPI support and improved power management for Rockchip SFC
controllers.
- Support for Atmel SAM7G5 QuadSPI and KEBA SPI controllers.

There's one big bit of work this time around, the addition of support for
a greater range of MBQ access sizes to SoundWire devices together with
support for deferred read/write. The MBQ register maps generally have
variable register sizes, the variable regiseter size support allows them
to be handled much more naturally within regmap with less open coding in
drivers. The deferred read/write support avoids spurious errors when
devices make use of a bus feature allowing them to indicate they're
busy. These changes pull in a supporting SoundWire change, and there's
an ASoC change building off the new code.
The remainder of the changes are code cleanups.

replacing RTNL lock with a per device-one to protect NAPI-related
net device data and moving synchronize_net() calls outside such

Pull networking updates from Paolo Abeni:
"This is slightly smaller than usual, with the most interesting work
being still around RTNL scope reduction.
Core:
- More core refactoring to reduce the RTNL lock contention, including
preparatory work for the per-network namespace RTNL lock, replacing
RTNL lock with a per device-one to protect NAPI-related net device
data and moving synchronize_net() calls outside such lock.

and more specific TCP coverage.

When the 'cachestat()' system call was added in commit cf264e1329
("cachestat: implement cachestat syscall"), it was meant to be a much
more convenient (and performant) version of mincore() that didn't need
mapping things into the user virtual address space in order to work.
But it ended up missing the "check for writability or ownership" fix for
mincore(), done in commit 134fca9063 ("mm/mincore.c: make mincore()
more conservative").
This just adds equivalent logic to 'cachestat()', modified for the file
context (rather than vma).

Merge tag 'selinux-pr-20250121' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux updates from Paul Moore:
- Extended permissions supported in conditional policy
The SELinux extended permissions, aka "xperms", allow security admins
to target individuals ioctls, and recently netlink messages, with
their SELinux policy. Adding support for conditional policies allows
admins to toggle the granular xperms using SELinux booleans, helping
pave the way for greater use of xperms in general purpose SELinux
policies. This change bumps the maximum SELinux policy version to 34.
- Fix a SCTP/SELinux error return code inconsistency
Depending on the loaded SELinux policy, specifically it's
EXTSOCKCLASS support, the bind(2) LSM/SELinux hook could return
different error codes due to the SELinux code checking the socket's
SELinux object class (which can vary depending on EXTSOCKCLASS) and
not the socket's sk_protocol field. We fix this by doing the obvious,
and looking at the sock->sk_protocol field instead of the object
class.
- Makefile fixes to properly cleanup av_permissions.h
Add av_permissions.h to "targets" so that it is properly cleaned up
using the kbuild infrastructure.
- A number of smaller improvements by Christian Göttsche
A variety of straightforward changes to reduce code duplication,
reduce pointer lookups, migrate void pointers to defined types,
simplify code, constify function parameters, and correct iterator
types.

Pull lsm updates from Paul Moore:
- Improved handling of LSM "secctx" strings through lsm_context struct
The LSM secctx string interface is from an older time when only one
LSM was supported, migrate over to the lsm_context struct to better
support the different LSMs we now have and make it easier to support
new LSMs in the future.
These changes explain the Rust, VFS, and networking changes in the
diffstat.
- Only build lsm_audit.c if CONFIG_SECURITY and CONFIG_AUDIT are
enabled
Small tweak to be a bit smarter about when we build the LSM's common
audit helpers.
- Check for absurdly large policies from userspace in SafeSetID
SafeSetID policies rules are fairly small, basically just "UID:UID",
it easy to impose a limit of KMALLOC_MAX_SIZE on policy writes which
helps quiet a number of syzbot related issues. While work is being
done to address the syzbot issues through other mechanisms, this is a
trivial and relatively safe fix that we can do now.
- Various minor improvements and cleanups
A collection of improvements to the kernel selftests, constification
of some function parameters, removing redundant assignments, and
local variable renames to improve readability.

Toolchain and infrastructure:
- Finish the move to custom FFI integer types started in the previous
cycle and finally map 'long' to 'isize' and 'char' to 'u8'. Do a few
cleanups on top thanks to that.
- Start to use 'derive(CoercePointee)' on Rust >= 1.84.0.
This is a major milestone on the path to build the kernel using only
stable Rust features. In particular, previously we were using the
unstable features 'coerce_unsized', 'dispatch_from_dyn' and 'unsize',
and now we will use the new 'derive_coerce_pointee' one, which is on
track to stabilization. This new feature is a macro that essentially
expands into code that internally uses the unstable features that we
were using before, without having to expose those.
With it, stable Rust users, including the kernel, will be able to
build custom smart pointers that work with trait objects, e.g.:
fn f(p: &Arc<dyn Display>) {
pr_info!("{p}\n");
}
let a: Arc<dyn Display> = Arc::new(42i32, GFP_KERNEL)?;
let b: Arc<dyn Display> = Arc::new("hello there", GFP_KERNEL)?;
f(&a); // Prints "42".
f(&b); // Prints "hello there".
Together with the 'arbitrary_self_types' feature that we started
using in the previous cycle, using our custom smart pointers like
'Arc' will eventually only rely in stable Rust.
- Introduce 'PROCMACROLDFLAGS' environment variable to allow to link
Rust proc macros using different flags than those used for linking
Rust host programs (e.g. when 'rustc' uses a different C library
than the host programs' one), which Android needs.
- Help kernel builds under macOS with Rust enabled by accomodating
other naming conventions for dynamic libraries (i.e. '.so' vs.
'.dylib') which are used for Rust procedural macros. The actual
support for macOS (i.e. the rest of the pieces needed) is provided
out-of-tree by others, following the policy used for other parts of
the kernel by Kbuild.
- Run Clippy for 'rusttest' code too and clean the bits it spotted.
- Provide Clippy with the minimum supported Rust version to improve
the suggestions it gives.
- Document 'bindgen' 0.71.0 regression.
'kernel' crate:
- 'build_error!': move users of the hidden function to the documented
macro, prevent such uses in the future by moving the function
elsewhere and add the macro to the prelude.
- 'types' module: add improved version of 'ForeignOwnable::borrow_mut'
(which was removed in the past since it was problematic); change
'ForeignOwnable' pointer type to '*mut'.
- 'alloc' module: implement 'Display' for 'Box' and align the 'Debug'
implementation to it; add example (doctest) for 'ArrayLayout::new()'.
- 'sync' module: document 'PhantomData' in 'Arc'; use
'NonNull::new_unchecked' in 'ForeignOwnable for Arc' impl.
- 'uaccess' module: accept 'Vec's with different allocators in
'UserSliceReader::read_all'.
- 'workqueue' module: enable run-testing a couple more doctests.
- 'error' module: simplify 'from_errno()'.
- 'block' module: fix formatting in code documentation (a lint to catch
these is being implemented).
- Avoid 'unwrap()'s in doctests, which also improves the examples by
showing how kernel code is supposed to be written.
- Avoid 'as' casts with 'cast{,_mut}' calls which are a bit safer.
And a few other cleanups.

1) Per-CPU kthreads must stay affine to a single CPU and never execute
relevant code on any other CPU. This is currently handled by smpboot
code which takes care of CPU-hotplug operations. Affinity here is
a correctness constraint.
2) Some kthreads _have_ to be affine to a specific set of CPUs and can't
run anywhere else. The affinity is set through kthread_bind_mask()
and the subsystem takes care by itself to handle CPU-hotplug
operations. Affinity here is assumed to be a correctness constraint.
3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This
is not a correctness constraint but merely a preference in terms of
memory locality. kswapd and kcompactd both fall into this category.
The affinity is set manually like for any other task and CPU-hotplug
is supposed to be handled by the relevant subsystem so that the task
is properly reaffined whenever a given CPU from the node comes up.
Also care should be taken so that the node affinity doesn't cross
isolated (nohz_full) cpumask boundaries.
4) Similar to the previous point except kthreads have a _preferred_
affinity different than a node. Both RCU boost kthreads and RCU
exp kworkers fall into this category as they refer to "RCU nodes"
from a distinctly distributed tree.
Currently the preferred affinity patterns (3 and 4) have at least 4
identified users, with more or less success when it comes to handle
CPU-hotplug operations and CPU isolation. Each of which do it in its own
ad-hoc way.
This is an infrastructure proposal to handle this with the following API
changes:
_ kthread_create_on_node() automatically affines the created kthread to
its target node unless it has been set as per-cpu or bound with
kthread_bind[_mask]() before the first wake-up.
- kthread_affine_preferred() is a new function that can be called right
after kthread_create_on_node() to specify a preferred affinity
different than the specified node.
When the preferred affinity can't be applied because the possible
targets are offline or isolated (nohz_full), the kthread is affine
to the housekeeping CPUs (which means to all online CPUs most of the
time or only the non-nohz_full CPUs when nohz_full= is set).
kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been
converted, along with a few old drivers.
Summary of the changes:
* Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu()
* Introduce task_cpu_fallback_mask() that defines the default last
resort affinity of a task to become nohz_full aware
* Add some correctness check to ensure kthread_bind() is always called
before the first kthread wake up.
* Default affine kthread to its preferred node.
* Convert kswapd / kcompactd and remove their halfway working ad-hoc
affinity implementation
* Implement kthreads preferred affinity
* Unify kthread worker and kthread API's style
* Convert RCU kthreads to the new API and remove the ad-hoc affinity
implementation.

The sorttable.c was a copy from recordmcount.c which is very hard to
maintain. That's because it uses macro helpers and places the code in a
header file sorttable.h to handle both the 64 bit and 32 bit version of
the Elf structures. It also uses _r()/r()/r2() wrappers around accessing
the data which will read the 64 bit or 32 bit version of the data as well
as handle endianess. If the wrong wrapper is used, an invalid value will
result, and this has been a cause for bugs in the past. In fact the new
ORC code doesn't even use it. That's fine because ORC is only for 64 bit
x86 which is the default parsing.
Instead of having a bunch of macros defined and then include the code
twice from a header, the Elf structures are each wrapped in a union. The
union holds the 64 bit and 32 bit version of the needed structure. Then
a structure of function pointers is used, along with helper macros
to access the ELF types appropriately for their byte size and endianess.
How to reference the data fields is moved from the code that implements
the sorting to the helper functions where all accesses to a field will
use he same helper function. As long as the helper functions access
the fields correctly, the code will also access the fields. This is
an improvement over having to code implementing the sorting having to
make sure it always uses the right accessor function when reading an
ELF field.
This is a clean up only, the functionality of the scripts/sorttable.c
does not change.

- Have fprobes built on top of function graph infrastructure
The fprobe logic is an optimized kprobe that uses ftrace to attach to
functions when a probe is needed at the start or end of the function. The
fprobe and kretprobe logic implements a similar method as the function
graph tracer to trace the end of the function. That is to hijack the
return address and jump to a trampoline to do the trace when the function
exits. To do this, a shadow stack needs to be created to store the
original return address. Fprobes and function graph do this slightly
differently. Fprobes (and kretprobes) has slots per callsite that are
reserved to save the return address. This is fine when just a few points
are traced. But users of fprobes, such as BPF programs, are starting to add
many more locations, and this method does not scale.
The function graph tracer was created to trace all functions in the
kernel. In order to do this, when function graph tracing is started, every
task gets its own shadow stack to hold the return address that is going to
be traced. The function graph tracer has been updated to allow multiple
users to use its infrastructure. Now have fprobes be one of those users.
This will also allow for the fprobe and kretprobe methods to trace the
return address to become obsolete. With new technologies like CFI that
need to know about these methods of hijacking the return address, going
toward a solution that has only one method of doing this will make the
kernel less complex.
- Cleanup with guard() and free() helpers
There were several places in the code that had a lot of "goto out" in the
error paths to either unlock a lock or free some memory that was
allocated. But this is error prone. Convert the code over to use the
guard() and free() helpers that let the compiler unlock locks or free
memory when the function exits.
- Remove disabling of interrupts in the function graph tracer
When function graph tracer was first introduced, it could race with
interrupts and NMIs. To prevent that race, it would disable interrupts and
not trace NMIs. But the code has changed to allow NMIs and also
interrupts. This change was done a long time ago, but the disabling of
interrupts was never removed. Remove the disabling of interrupts in the
function graph tracer is it is not needed. This greatly improves its
performance.
- Allow the :mod: command to enable tracing module functions on the kernel
command line.
The function tracer already has a way to enable functions to be traced in
modules by writing ":mod:<module>" into set_ftrace_filter. That will
enable either all the functions for the module if it is loaded, or if it
is not, it will cache that command, and when the module is loaded that
matches <module>, its functions will be enabled. This also allows init
functions to be traced. But currently events do not have that feature.
Because enabling function tracing can be done very early at boot up
(before scheduling is enabled), the commands that can be done when
function tracing is started is limited. Having the ":mod:" command to
trace module functions as they are loaded is very useful. Update the
kernel command line function filtering to allow it.

- Clean up the __rb_map_vma() logic
The logic of __rb_map_vma() has a error check with WARN_ON() that makes
sure that the index does not go past the end of the array of buffers. The
test in the loop pretty much guarantees that it will never happen, but
since the relation of the variables used is a little complex, the
WARN_ON() check was added. It was noticed that the array was dereferenced
before this check and if the logic does break and for some reason the
logic goes past the array, there will be an out of bounds access here.
Move the access to after the WARN_ON().
- Consolidate how the ring buffer is determined to be empty
Currently there's two ways that are used to determine if the ring buffer
is empty. One relies on the status of the commit and reader pages and what
was read, and the other is on what was written vs what was read. By using
the number of entries (written) method, it can be used for reading events
that are out of the kernel's control (what pKVM will use). Move to this
method to make it easier to implement a pKVM ring buffer that the kernel
can read.

Pull slab updates from Vlastimil Babka:
- Move the kfree_rcu() implementation from RCU to SLAB subsystem
(Uladzislau Rezki)
The kfree_rcu() implementation has been historically maintained in
the RCU subsystem. At LSF/MM we agreed to move it to SLAB, where it
more logically belongs. The batching is planned be more integrated
with SLUB internals in the future, while using the RCU APIs like any
other subsystem.
- Fix for kernel-doc warning (Randy Dunlap)
* tag 'slab-for-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab:
mm/slab: fix kernel-doc func param names
mm/slab: Move kvfree_rcu() into SLAB
rcu/kvfree: Adjust a shrinker name
rcu/kvfree: Adjust names passed into trace functions
rcu/kvfree: Move some functions under CONFIG_TINY_RCU
rcu/kvfree: Initialize kvfree_rcu() separately
- Consolidation of the machine_kexec_mask_interrupts() by providing a
generic implementation and replacing the copy & pasta orgy in the
relevant architectures.
- Prevent unconditional operations on interrupt chips during kexec
shutdown, which can trigger warnings in certain cases when the
underlying interrupt has been shut down before.
- Make the enforcement of interrupt handling in interrupt context
unconditionally available, so that it actually works for non x86
related interrupt chips. The earlier enablement for ARM GIC chips set
the required chip flag, but did not notice that the check was hidden
behind a config switch which is not selected by ARM[64].
- Decrapify the handling of deferred interrupt affinity setting. Some
interrupt chips require that affinity changes are made from the context
of handling an interrupt to avoid certain race conditions. For x86 this
was the default, but with interrupt remapping this requirement was
lifted and a flag was introduced which tells the core code that
affinity changes can be done in any context. Unrestricted affinity
changes are the default for the majority of interrupt chips. RISCV has
the requirement to add the deferred mode to one of it's interrupt
controllers, but with the original implementation this would require to
add the any context flag to all other RISC-V interrupt chips. That's
backwards, so reverse the logic and require that chips, which need the
deferred mode have to be marked accordingly. That avoids chasing the
'sane' chips and marking them.
- Add multi-node support to the Loongarch AVEC interrupt controller
driver.
- The usual tiny cleanups, fixes and improvements all over the place.
