Pull tracing updates from Steven Rostedt:
- 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.
- Update the Rust tracepoint code to use the C code too
There was some duplication of the tracepoint code for Rust that did
the same logic as the C code. Add a helper that makes it possible for
both algorithms to use the same logic in one place.
- Add poll to trace event hist files
It is useful to know when an event is triggered, or even with some
filtering. Since hist files of events get updated when active and the
event is triggered, allow applications to poll the hist file and wake
up when an event is triggered. This will let the application know
that the event it is waiting for happened.
- Add :mod: command to enable events for current or future modules
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.
Add the command where if ':mod:<module>' is written into set_event,
then either all the modules events are enabled if it is loaded, or
cache it so that the module's events are enabled when it is loaded.
This also works from the kernel command line, where
"trace_event=:mod:<module>", when the module is loaded at boot up,
its events will be enabled then.

Pull probes updates from Masami Hiramatsu:
- kprobes: Cleanups using guard() and __free(): Use cleanup.h macros to
cleanup code and remove all gotos from kprobes code.
- tracing/probes: Also cleanups tracing/*probe events code with guard()
and __free(). These patches are just to simplify the parser codes.
- kprobes: Reduce preempt disable scope in check_kprobe_access_safe()
This reduces preempt disable time to only when getting the module
refcount in check_kprobe_access_safe().
Previously it disabled preempt needlessly for other checks including
jump_label_text_reserved(), which took a long time because of the
linear search.

Pull fsnotify pre-content notification support from Jan Kara:
"This introduces a new fsnotify event (FS_PRE_ACCESS) that gets
generated before a file contents is accessed.
The event is synchronous so if there is listener for this event, the
kernel waits for reply. On success the execution continues as usual,
on failure we propagate the error to userspace. This allows userspace
to fill in file content on demand from slow storage. The context in
which the events are generated has been picked so that we don't hold
any locks and thus there's no risk of a deadlock for the userspace
handler.
The new pre-content event is available only for users with global
CAP_SYS_ADMIN capability (similarly to other parts of fanotify
functionality) and it is an administrator responsibility to make sure
the userspace event handler doesn't do stupid stuff that can DoS the
system.
Based on your feedback from the last submission, fsnotify code has
been improved and now file->f_mode encodes whether pre-content event
needs to be generated for the file so the fast path when nobody wants
pre-content event for the file just grows the additional file->f_mode
check. As a bonus this also removes the checks whether the old
FS_ACCESS event needs to be generated from the fast path. Also the
place where the event is generated during page fault has been moved so
now filemap_fault() generates the event if and only if there is no
uptodate folio in the page cache.
Also we have dropped FS_PRE_MODIFY event as current real-world users
of the pre-content functionality don't really use it so let's start
with the minimal useful feature set"

hrtimers are migrated away from the dying CPU to any online target at
the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers
handling tasks involved in the CPU hotplug forward progress.
However wakeups can still be performed by the outgoing CPU after
CPUHP_AP_HRTIMERS_DYING. Those can result again in bandwidth timers being
armed. Depending on several considerations (crystal ball power management
based election, earliest timer already enqueued, timer migration enabled or
not), the target may eventually be the current CPU even if offline. If that
happens, the timer is eventually ignored.
The most notable example is RCU which had to deal with each and every of
those wake-ups by deferring them to an online CPU, along with related
workarounds:
_ e787644caf76 (rcu: Defer RCU kthreads wakeup when CPU is dying)
_ 9139f93209d1 (rcu/nocb: Fix RT throttling hrtimer armed from offline CPU)
_ f7345ccc62a4 (rcu/nocb: Fix rcuog wake-up from offline softirq)
The problem isn't confined to RCU though as the stop machine kthread
(which runs CPUHP_AP_HRTIMERS_DYING) reports its completion at the end
of its work through cpu_stop_signal_done() and performs a wake up that
eventually arms the deadline server timer:
WARNING: CPU: 94 PID: 588 at kernel/time/hrtimer.c:1086 hrtimer_start_range_ns+0x289/0x2d0

cpu_stopper_thread
Instead of providing yet another bandaid to work around the situation, fix
it in the hrtimers infrastructure instead: always migrate away a timer to
an online target whenever it is enqueued from an offline CPU.
This will also allow to revert all the above RCU disgraceful hacks.

init_once is called when an object doesn't come from the cache, and
hence needs initial clearing of certain members. While the whole
struct could get cleared by memset() in that case, a few of the cache
members are large enough that this may cause unnecessary overhead if
the caches used aren't large enough to satisfy the workload. For those
cases, some churn of kmalloc+kfree is to be expected.
Ensure that the 3 users that need clearing put the members they need
cleared at the start of the struct, and wrap the rest of the struct in
a struct group so the offset is known.
While at it, improve the interaction with KASAN such that when/if
KASAN writes to members inside the struct that should be retained over
caching, it won't trip over itself. For rw and net, the retaining of
the iovec over caching is disabled if KASAN is enabled. A helper will
free and clear those members in that case.

RV per-task monitors are implemented through a monitor structure
available for each task_struct. This structure is reset every time the
monitor is (re-)started, to avoid inconsistencies if the monitor was
activated previously.
To do so, we reset the monitor on all threads using the macro
for_each_process_thread. However, this macro excludes the idle tasks on
each CPU. Idle tasks could be considered tasks on their own right and it
should be up to the model whether to ignore them or not.
Reset monitors also on the idle tasks for each present CPU whenever we
reset all per-task monitors.

Pull CRC updates from Eric Biggers:
- Reorganize the architecture-optimized CRC32 and CRC-T10DIF code to be
directly accessible via the library API, instead of requiring the
crypto API. This is much simpler and more efficient.
- Convert some users such as ext4 to use the CRC32 library API instead
of the crypto API. More conversions like this will come later.
- Add a KUnit test that tests and benchmarks multiple CRC variants.
Remove older, less-comprehensive tests that are made redundant by
this.
- Add an entry to MAINTAINERS for the kernel's CRC library code. I'm
volunteering to maintain it. I have additional cleanups and
optimizations planned for future cycles.

Pull ACPI updates from Rafael Wysocki:
"The most significant change here is replacing msleep() in
acpi_os_sleep() with usleep_range() to reduce spurious sleep time due
to timer inaccuracy which may spectacularly reduce the duration of
system suspend and resume transitions on some systems.
All of the other changes fall into the fixes and cleanups category
this time.
Specifics:
- Use usleep_range() instead of msleep() in acpi_os_sleep() to reduce
excessive delays due to timer inaccuracy, mostly affecting system
suspend and resume (Rafael Wysocki)
- Use str_enabled_disabled() string helpers in the ACPI tables
parsing code to make it easier to follow (Sunil V L)
- Update device properties parsing on systems using ACPI so that data
firmware nodes resulting from _DSD evaluation are treated as
available in firmware nodes walks (Sakari Ailus)
- Fix missing guid_t declaration in linux/prmt.h (Robert Richter)
- Update the GHES handling code to follow the global panic= policy
instead of overriding it by force-rebooting the system after a
fatal HW error has been reported (Borislav Petkov)
- Update messages printed by the ACPI battery driver to always refer
to driver extensions as "hooks" to avoid confusion with similar
functionality in the power supply subsystem in the future (Thomas
Weißschuh)
- Fix .probe() error path cleanup in the ACPI fan driver to avoid
memory leaks (Joe Hattori)
- Constify 'struct bin_attribute' in some places in the ACPI
subsystem and mark it as __ro_after_init in one place to prevent
binary blob attributes from being updated (Thomas Weißschuh)
- Add empty stubs for several ACPI-related symbols so that they can
be used when CONFIG_ACPI is unset and use them for removing
unnecessary conditional compilation from the ipu-bridge driver
(Ricardo Ribalda)"

utility updates.
Included are some pieces of new hardware support, like the addition of
Clearwater Forest processors support to intel_idle, new cpufreq driver
for Airoha SoCs, and Apple cpufreq driver extensions to support more
SoCs. The intel_pstate driver is also extended to be able to support
new platforms by using ACPI CPPC to compute scaling factors between

for consistency with CPU offline (Christian Loehle)
- Fix superfluous updates caused by need_freq_update in the schedutil
cpufreq governor (Sultan Alsawaf)
- Allow configuring the system suspend-resume (DPM) watchdog to warn
earlier than panic (Douglas Anderson)
- Implement devm_device_init_wakeup() helper and introduce a device-
managed variant of dev_pm_set_wake_irq() (Joe Hattori, Peng Fan)

Pull regmap updates from Mark Brown:
"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"

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
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.
- Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
and more specific TCP coverage.
- Reduce network namespace tear-down time by removing per-subsystems
synchronize_net() in tipc and sched.
- Add flow label selector support for fib rules, allowing traffic
redirection based on such header field.
Netfilter:
- Do not remove netdev basechain when last device is gone, allowing
netdev basechains without devices.
- Revisit the flowtable teardown strategy, dealing better with fin,
reset and re-open events.
- Scale-up IP-vs connection dumping by avoiding linear search on each
restart.
Protocols:
- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core
- Better scaling of ICMP rate-limiting, by removing false-sharing in
inet peers handling.
- Introduces netlink notifications for multicast IPv4 and IPv6
address changes.
- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.
- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
avoid local port exhaustion issues when the average connection
lifetime is very short.
- Support updating keys (re-keying) for connections using kernel TLS
(for TLS 1.3 only).
- Support ipv4-mapped ipv6 address clients in smc-r v2.
- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.
- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.
Driver API:
- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.
- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.
- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W
implementation.
- Consolidate DSA drivers Energy Efficiency Ethernet support.
- Add EEE management to phylink, making use of the phylib
implementation.
- Add phylib support for in-band capabilities negotiation.
- Simplify how phylib-enabled mac drivers expose the supported
interfaces.
Tests and tooling:
- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.
- Increase TCP selftest coverage importing several packetdrill
test-cases.
- Regenerate the ethtool uapi header from the YNL spec, to ease
maintenance and future development.

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.

The function graph infrastructure is now generic so that kretprobes,
fprobes and BPF can use it. But there is still some leftover logic that
only the function graph tracer itself uses. This is the calculation of the
calltime and return time of the functions. The calculation of the calltime
has been moved into the function graph tracer and those users that need it
so that it doesn't cause overhead to the other users. But the return
function timestamp was still called.
Instead of just moving the taking of the timestamp into the function graph
trace remove the calltime and rettime completely from the ftrace_graph_ret
structure. Instead, move it into the function graph return entry event
structure and this also moves all the calltime and rettime logic out of
the generic fgraph.c code and into the tracing code that uses it.
This has been reported to decrease the overhead by ~27%.

Pull kthread updates from Frederic Weisbecker:
"Kthreads affinity follow either of 4 existing different patterns:
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"

Remove duplicate macro PCI_VSEC_HDR and its related macro
PCI_VSEC_HDR_LEN_SHIFT from pci_regs.h to avoid redundancy and
inconsistencies. Update VFIO PCI code to use PCI_VNDR_HEADER and
PCI_VNDR_HEADER_LEN() for consistent naming and functionality.
These changes aim to streamline header handling while minimizing impact,
given the niche usage of these macros in userspace.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ftrace updates from Steven Rostedt:
- 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.

Pull interrupt subsystem updates from Thomas Gleixner:
- Consolidate 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.
