Pull module updates from Sami Tolvanen:
"Kernel symbol flags:
- Replace the separate *_gpl symbol sections (__ksymtab_gpl and
__kcrctab_gpl) with a unified symbol table and a new __kflagstab
section.
This section stores symbol flags, such as the GPL-only flag, as an
8-bit bitset for each exported symbol. This is a cleanup that
simplifies symbol lookup in the module loader by avoiding table
fragmentation and will allow a cleaner way to add more flags later
if needed.
Module signature UAPI:
- Move struct module_signature to the UAPI headers to allow reuse by
tools outside the kernel proper, such as kmod and
scripts/sign-file.
This also renames a few constants for clarity and drops unused
signature types as preparation for hash-based module integrity
checking work that's in progress.
Sysfs:
- Add a /sys/module/<module>/import_ns sysfs attribute to show the
symbol namespaces imported by loaded modules.
This makes it easier to verify driver API access at runtime on
systems that care about such things (e.g. Android).
Cleanups and fixes:
- Force sh_addr to 0 for all sections in module.lds. This prevents
non-zero section addresses when linking modules with 'ld.bfd -r',
which confused elfutils.
- Fix a memory leak of charp module parameters on module unload when
the kernel is configured with CONFIG_SYSFS=n.
- Override the -EEXIST error code returned by module_init() to
userspace. This prevents confusion with the errno reserved by the
module loader to indicate that a module is already loaded.
- Simplify the warning message and drop the stack dump on positive
returns from module_init().
- Drop unnecessary extern keywords from function declarations and
synchronize parse_args() arguments with their implementation"

Pull arm64 updates from Catalin Marinas:
"The biggest changes are MPAM enablement in drivers/resctrl and new PMU
support under drivers/perf.
On the core side, FEAT_LSUI lets futex atomic operations with EL0
permissions, avoiding PAN toggling.
The rest is mostly TLB invalidation refactoring, further generic entry
work, sysreg updates and a few fixes.
Core features:
- Add support for FEAT_LSUI, allowing futex atomic operations without
toggling Privileged Access Never (PAN)
- Further refactor the arm64 exception handling code towards the
generic entry infrastructure
- Optimise __READ_ONCE() with CONFIG_LTO=y and allow alias analysis
through it
Memory management:
- Refactor the arm64 TLB invalidation API and implementation for
better control over barrier placement and level-hinted invalidation
- Enable batched TLB flushes during memory hot-unplug
- Fix rodata=full block mapping support for realm guests (when
BBML2_NOABORT is available)
Perf and PMU:
- Add support for a whole bunch of system PMUs featured in NVIDIA's
Tegra410 SoC (cspmu extensions for the fabric and PCIe, new drivers
for CPU/C2C memory latency PMUs)
- Clean up iomem resource handling in the Arm CMN driver
- Fix signedness handling of AA64DFR0.{PMUVer,PerfMon}
MPAM (Memory Partitioning And Monitoring):
- Add architecture context-switch and hiding of the feature from KVM
- Add interface to allow MPAM to be exposed to user-space using
resctrl
- Add errata workaround for some existing platforms
- Add documentation for using MPAM and what shape of platforms can
use resctrl
Miscellaneous:
- Check DAIF (and PMR, where relevant) at task-switch time
- Skip TFSR_EL1 checks and barriers in synchronous MTE tag check mode
(only relevant to asynchronous or asymmetric tag check modes)
- Remove a duplicate allocation in the kexec code
- Remove redundant save/restore of SCS SP on entry to/from EL0
- Generate the KERNEL_HWCAP_ definitions from the arm64 hwcap
descriptions

Add a sample application for WireGuard, using the generated C library.
The main benefit of this is to exercise the generated library,
which might be useful for future self-tests.
Example:
$ make -C tools/net/ynl/lib
$ make -C tools/net/ynl/generated
$ make -C tools/net/ynl/tests wireguard
$ ./tools/net/ynl/tests/wireguard
usage: ./tools/net/ynl/tests/wireguard <ifindex|ifname>
$ sudo ./tools/net/ynl/tests/wireguard wg-test

Add further netkit queue-lease coverage for netns lifecycle of the guest
and physical halves, channel resize across active leases, single-device
and multi-lessee scenarios, L3 mode operation, lease capacity exhaustion,
and corner-cases of e.g. queue-create rejection paths. Also make the tests
more robust by removing the time.sleep(0.1) after netns deletion and turn
them into a wait loop.

As pointed out in 3d2c3d2eea9a ("selftests: net: py: explicitly forbid
multiple ksft_run() calls"), ksft_run() cannot be called multiple times.
Move the netdevsim-based queue lease tests to selftests/net/ so that
each file has exactly one ksft_run() call.

YnlFamily opens an AF_NETLINK socket in __init__ but has no way
to release it other than leaving it to the GC. YnlFamily holds a
self reference cycle through SpecFamily's self.family = self
in its super().__init__() call, so refcount GC cannot reclaim
it and the socket stays open until the cyclic GC runs.
If a test creates a guest netns, instantiates a YnlFamily inside
it via NetNSEnter(), performs some test case work via Ynl, and
then deletes the netns, then the 'ip netns del' only drops the
mount binding and cleanup_net in the kernel never runs, so any
subsequent test case assertions that objects got cleaned up would
fail given this only gets triggered later via cyclic GC run.
Add an explicit close() that closes the netlink socket and wire
up the __enter__/__exit__ so callers can scope the instance
deterministically via 'with YnlFamily(...) as ynl: ...'.

Add a selftest that reproduces the null-ptr-deref in
bond_rr_gen_slave_id() when XDP redirect targets a bond device in
round-robin mode that was never brought up. The test verifies the fix
by ensuring no crash occurs.
Test setup:
- bond0: active-backup mode, UP, with native XDP (enables
bpf_master_redirect_enabled_key globally)
- bond1: round-robin mode, never UP
- veth1: slave of bond1, with generic XDP (XDP_TX)
- BPF_PROG_TEST_RUN with live frames triggers the redirect path

Remove the inclusion of ../filesystems/utils.h from listns_efault_test.c.
The test doesn't use any symbols from that header. Including it alongside
../pidfd/pidfd.h causes a build failure because both headers define
wait_for_pid() with conflicting linkage:
../filesystems/utils.h: extern int wait_for_pid(pid_t pid);
../pidfd/pidfd.h: static inline int wait_for_pid(pid_t pid)

Currently, the initialization of loongarch_jump_ops does not contain an
assignment to its .free field. This causes disasm_line__free() to fall
through to ins_ops__delete() for LoongArch jump instructions.
ins_ops__delete() will free ins_operands.source.raw and
ins_operands.source.name, and these fields overlaps with
ins_operands.jump.raw_comment and ins_operands.jump.raw_func_start.
Since in loongarch_jump__parse(), these two fields are populated by
strchr()-ing the same buffer, trying to free them will lead to undefined
behavior.
This invalid free usually leads to crashes:

When filtering branch stack samples on user events they sample in user
land but may have come from the kernel. Aarch64 avoids leaking the
kernel address for kaslr reasons but other platforms, for now,
don't. Be more permissive in allowing kernel addresses in the source
of user branch stacks.
When filtering branch stack samples on kernel events they sample in
kernel land but may have come from user land. Avoid the target being a
user address but allow the source to be in user land. Aarch64 may not
leak the user land addresses (making them 0) but other platforms
do. As the kernel address sampling implies privelege, just allow this.
Increase the duration of the system call sampling test to make the
likelihood of sampling a system call higher (increased from 1000 to
8000 loops - a number found through experimentation on an Intel
Tigerlake laptop), also make the period of the event a prime number.
Put unneeded perf record output into a temporary file so that the test
output isn't cluttered. More clearly state which test is running and
the pass, fail or skipped result of the test.
These changes make the test on an Intel tigerlake laptop reliably pass
rather than reliably fail.

When adding a probe for libc's inet_pton, perf probe may create multiple
probe points (e.g., due to inlining or multiple symbol resolutions),
resulting in multiple identical event names being output (e.g.,
`probe_libc:inet_pton_1`).
The script previously used a brittle pipeline (`tail -n +2 | head -n -5`)
and an awk script to extract the event name. When multiple probes were
added, awk would output the event name multiple times, which expanded
to multiple words in bash. This broke the subsequent `perf record` and
`perf probe -d` commands, causing the test to fail with:
`Error: another command except --add is set.`
Fix this by removing the brittle `tail/head` commands and appending
`| head -n 1` to the awk extraction. This ensures that only a single,
unique event name is captured, regardless of how many probe points
are created.
Additionally, the test artificially limited the backtrace size via
`max-stack=4` and did not specify dwarf call graphs for non-s390x
architectures. In newer libc versions where `inet_pton` is nested
deeper or compiled without frame pointers, `perf script` failed to resolve
the backtrace up to `/bin/ping`. Fix this by explicitly collecting
dwarf call-graphs for all architectures and increasing `max-stack` to 8.

Turns out that displaying "RM $^" via quiet_cmd_rm can also upset the
shell and cause it to display "argument list too long".
Trying to quote $^ doesn't help.
In the end, *not* displaying the (potentially long) list of files is
probably the right thing to do for a "quiet" message, anyway. Instead,
let's display a count of how many files were removed. There is always
V=1 if more detail is required.
TEST linux/tools/perf/pmu-events/metric_test.log

Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.
There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software
nodes
- allow matching GPIO controllers by secondary firmware node if
matching by primary does not succeed
- demote deferral warnings to debug level as they are quite normal
when using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig
by default
- rework several core functions in preparation for the upcoming
Revocable helper library for protecting resources against sudden
removal, this reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by
using FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs
- replace snprintf() with strscpy() where formatting is not required
New drivers:
- add the gpio-by-pinctrl generic driver using the ARM SCMI protocol
to control GPIOs (along with SCMI changes pulled from the pinctrl
tree)
- add a driver providing support for handling of platform events via
GPIO-signalled ACPI events (used on Intel Nova Lake and later
platforms)
Driver changes:
- extend the gpio-kempld driver with support for more recent models,
interrupts and setting/getting multiple values at once
- improve interrupt handling in gpio-brcmstb
- add support for multi-SoC systems in gpio-tegra186
- make sure we return correct values from the .get() callbacks in
several GPIO drivers by normalizing any values other than 0, 1 or
negative error numbers
- use flexible arrays in several drivers to reduce the number of
required memory allocations
- simplify synchronous waiting for virtual drivers to probe and
remove the dedicated, a bit overengineered helper library
dev-sync-probe
- remove unneeded Kconfig dependencies on OF_GPIO in several drivers
and subsystems
- convert the two remaining users of of_get_named_gpio() to using
GPIO descriptors and remove the (no longer used) function along
with the header that declares it
- add missing includes in gpio-mmio
- shrink and simplify code in gpio-max732x by using guard(mutex)
- remove duplicated code handling the 'ngpios' property from
gpio-ts4800, it's already handled in GPIO core
- use correct variable type in gpio-aspeed
- add support for a new model in gpio-realtek-otto
- allow to specify the active-low setting of simulated hogs over the
configfs interface (in addition to existing devicetree support) in
gpio-sim
Bug fixes:
- clear the OF_POPULATED flag on hog nodes in GPIO chip remove path

Pull power management updates from Rafael Wysocki:
"Once again, cpufreq is the most active development area, mostly
because of the new feature additions and documentation updates in the
amd-pstate driver, but there are also changes in the cpufreq core
related to boost support and other assorted updates elsewhere.
Next up are power capping changes due to the major cleanup of the
Intel RAPL driver.
On the cpuidle front, a new C-states table for Intel Panther Lake is
added to the intel_idle driver, the stopped tick handling in the menu
and teo governors is updated, and there are a couple of cleanups.
Apart from the above, support for Tegra114 is added to devfreq and
there are assorted cleanups of that code, there are also two updates
of the operating performance points (OPP) library, two minor updates
related to hibernation, and cpupower utility man pages updates and
cleanups.
Specifics:
- Update qcom-hw DT bindings to include Eliza hardware (Abel Vesa)
- Update cpufreq-dt-platdev blocklist (Faruque Ansari)
- Minor updates to driver and dt-bindings for Tegra (Thierry Reding,
Rosen Penev)
- Add MAINTAINERS entry for CPPC driver (Viresh Kumar)
- Add support for new features: CPPC performance priority, Dynamic
EPP, Raw EPP, and new unit tests for them to amd-pstate (Gautham
Shenoy, Mario Limonciello)
- Fix sysfs files being present when HW missing and broken/outdated
documentation in the amd-pstate driver (Ninad Naik, Gautham Shenoy)
- Pass the policy to cpufreq_driver->adjust_perf() to avoid using
cpufreq_cpu_get() in the .adjust_perf() callback in amd-pstate
which leads to a scheduling-while-atomic bug (K Prateek Nayak)
- Clean up dead code in Kconfig for cpufreq (Julian Braha)
- Remove max_freq_req update for pre-existing cpufreq policy and add
a boost_freq_req QoS request to save the boost constraint instead
of overwriting the last scaling_max_freq constraint (Pierre
Gondois)
- Embed cpufreq QoS freq_req objects in cpufreq policy so they all
are allocated in one go along with the policy to simplify lifetime
rules and avoid error handling issues (Viresh Kumar)
- Use DMI max speed when CPPC is unavailable in the acpi-cpufreq
scaling driver (Henry Tseng)
- Switch policy_is_shared() in cpufreq to using cpumask_nth() instead
of cpumask_weight() because the former is more efficient (Yury
Norov)
- Use sysfs_emit() in sysfs show functions for cpufreq governor
attributes (Thorsten Blum)
- Update intel_pstate to stop returning an error when "off" is
written to its status sysfs attribute while the driver is already
off (Fabio De Francesco)
- Include current frequency in the debug message printed by
__cpufreq_driver_target() (Pengjie Zhang)
- Refine stopped tick handling in the menu cpuidle governor and
rearrange stopped tick handling in the teo cpuidle governor (Rafael
Wysocki)
- Add Panther Lake C-states table to the intel_idle driver (Artem
Bityutskiy)
- Clean up dead dependencies on CPU_IDLE in Kconfig (Julian Braha)
- Simplify cpuidle_register_device() with guard() (Huisong Li)
- Use performance level if available to distinguish between rates in
OPP debugfs (Manivannan Sadhasivam)
- Fix scoped_guard in dev_pm_opp_xlate_required_opp() (Viresh Kumar)
- Return -ENODATA if the snapshot image is not loaded (Alberto
Garcia)
- Remove inclusion of crypto/hash.h from hibernate_64.c on x86 (Eric
Biggers)
- Clean up and rearrange the intel_rapl power capping driver to make
the respective interface drivers (TPMI, MSR, and MMOI) hold their
own settings and primitives and consolidate PL4 and PMU support
flags into rapl_defaults (Kuppuswamy Sathyanarayanan)
- Correct kernel-doc function parameter names in the power capping
core code (Randy Dunlap)
- Remove unneeded casting for HZ_PER_KHZ in devfreq (Andy Shevchenko)
- Use _visible attribute to replace create/remove_sysfs_files() in
devfreq (Pengjie Zhang)
- Add Tegra114 support to activity monitor device in tegra30-devfreq
as a preparation to upcoming EMC controller support (Svyatoslav
Ryhel)
- Fix mistakes in cpupower man pages, add the boost and epp options
to the cpupower-frequency-info man page, and add the perf-bias
option to the cpupower-info man page (Roberto Ricci)
- Remove unnecessary extern declarations from getopt.h in arguments
parsing functions in cpufreq-set, cpuidle-info, cpuidle-set,
cpupower-info, and cpupower-set utilities (Kaushlendra Kumar)"

Pull driver core updates from Danilo Krummrich:
"debugfs:
- Fix NULL pointer dereference in debugfs_create_str()
- Fix misplaced EXPORT_SYMBOL_GPL for debugfs_create_str()
- Fix soundwire debugfs NULL pointer dereference from uninitialized
firmware_file
device property:
- Make fwnode flags modifications thread safe; widen the field to
unsigned long and use set_bit() / clear_bit() based accessors
- Document how to check for the property presence
devres:
- Separate struct devres_node from its "subclasses" (struct devres,
struct devres_group); give struct devres_node its own release and
free callbacks for per-type dispatch
- Introduce struct devres_action for devres actions, avoiding the
ARCH_DMA_MINALIGN alignment overhead of struct devres
- Export struct devres_node and its init/add/remove/dbginfo
primitives for use by Rust Devres<T>
- Fix missing node debug info in devm_krealloc()
- Use guard(spinlock_irqsave) where applicable; consolidate unlock
paths in devres_release_group()
driver_override:
- Convert PCI, WMI, vdpa, s390/cio, s390/ap, and fsl-mc to the
generic driver_override infrastructure, replacing per-bus
driver_override strings, sysfs attributes, and match logic; fixes a
potential UAF from unsynchronized access to driver_override in bus
match() callbacks
- Simplify __device_set_driver_override() logic
kernfs:
- Send IN_DELETE_SELF and IN_IGNORED inotify events on kernfs file
and directory removal
- Add corresponding selftests for memcg
platform:
- Allow attaching software nodes when creating platform devices via a
new 'swnode' field in struct platform_device_info
- Add kerneldoc for struct platform_device_info
software node:
- Move software node initialization from postcore_initcall() to
driver_init(), making it available early in the boot process
- Move kernel_kobj initialization (ksysfs_init) earlier to support
the above
- Remove software_node_exit(); dead code in a built-in unit
SoC:
- Introduce of_machine_read_compatible() and of_machine_read_model()
OF helpers and export soc_attr_read_machine() to replace direct
accesses to of_root from SoC drivers; also enables
CONFIG_COMPILE_TEST coverage for these drivers
sysfs:
- Constify attribute group array pointers to
'const struct attribute_group *const *' in sysfs functions,
device_add_groups() / device_remove_groups(), and struct class
Rust:
- Devres:
- Embed struct devres_node directly in Devres<T> instead of going
through devm_add_action(), avoiding the extra allocation and the
unnecessary ARCH_DMA_MINALIGN alignment
- I/O:
- Turn IoCapable from a marker trait into a functional trait
carrying the raw I/O accessor implementation (io_read /
io_write), providing working defaults for the per-type Io
methods
- Add RelaxedMmio wrapper type, making relaxed accessors usable in
code generic over the Io trait
- Remove overloaded per-type Io methods and per-backend macros
from Mmio and PCI ConfigSpace
- I/O (Register):
- Add IoLoc trait and generic read/write/update methods to the Io
trait, making I/O operations parameterizable by typed locations
- Add register! macro for defining hardware register types with
typed bitfield accessors backed by Bounded values; supports
direct, relative, and array register addressing
- Add write_reg() / try_write_reg() and LocatedRegister trait
- Update PCI sample driver to demonstrate the register! macro
Example:
```
register! {
/// UART control register.
CTRL(u32) @ 0x18 {
/// Receiver enable.
19:19 rx_enable => bool;
/// Parity configuration.
14:13 parity ?=> Parity;
}
/// FIFO watermark and counter register.
WATER(u32) @ 0x2c {
/// Number of datawords in the receive FIFO.
26:24 rx_count;
/// RX interrupt threshold.
17:16 rx_water;
}
}
impl WATER {
fn rx_above_watermark(&self) -> bool {
self.rx_count() > self.rx_water()
}
}
fn init(bar: &pci::Bar<BAR0_SIZE>) {
let water = WATER::zeroed()
.with_const_rx_water::<1>(); // > 3 would not compile
bar.write_reg(water);
let ctrl = CTRL::zeroed()
.with_parity(Parity::Even)
.with_rx_enable(true);
bar.write_reg(ctrl);
}
fn handle_rx(bar: &pci::Bar<BAR0_SIZE>) {
if bar.read(WATER).rx_above_watermark() {
// drain the FIFO
}
}
fn set_parity(bar: &pci::Bar<BAR0_SIZE>, parity: Parity) {
bar.update(CTRL, |r| r.with_parity(parity));
}
```
- IRQ:
- Move 'static bounds from where clauses to trait declarations for
IRQ handler traits

- Enable the generic_arg_infer Rust feature
- Extend Bounded with shift operations, single-bit bool
conversion, and const get()
Misc:
- Make deferred_probe_timeout default a Kconfig option

Pull crypto library updates from Eric Biggers:
- Migrate more hash algorithms from the traditional crypto subsystem to
lib/crypto/
Like the algorithms migrated earlier (e.g. SHA-*), this simplifies
the implementations, improves performance, enables further
simplifications in calling code, and solves various other issues:
- AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC)
- Support these algorithms in lib/crypto/ using the AES library
and the existing arm64 assembly code
- Reimplement the traditional crypto API's "cmac(aes)",
"xcbc(aes)", and "cbcmac(aes)" on top of the library
- Convert mac80211 to use the AES-CMAC library. Note: several
other subsystems can use it too and will be converted later
- Drop the broken, nonstandard, and likely unused support for
"xcbc(aes)" with key lengths other than 128 bits
- Enable optimizations by default
- GHASH
- Migrate the standalone GHASH code into lib/crypto/
- Integrate the GHASH code more closely with the very similar
POLYVAL code, and improve the generic GHASH implementation to
resist cache-timing attacks and use much less memory
- Reimplement the AES-GCM library and the "gcm" crypto_aead
template on top of the GHASH library. Remove "ghash" from the
crypto_shash API, as it's no longer needed
- Enable optimizations by default
- SM3
- Migrate the kernel's existing SM3 code into lib/crypto/, and
reimplement the traditional crypto API's "sm3" on top of it
- I don't recommend using SM3, but this cleanup is worthwhile
to organize the code the same way as other algorithms
- Testing improvements:
- Add a KUnit test suite for each of the new library APIs
- Migrate the existing ChaCha20Poly1305 test to KUnit
- Make the KUnit all_tests.config enable all crypto library tests
- Move the test kconfig options to the Runtime Testing menu
- Other updates to arch-optimized crypto code:
- Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine
- Remove some MD5 implementations that are no longer worth keeping
- Drop big endian and voluntary preemption support from the arm64
code, as those configurations are no longer supported on arm64
- Make jitterentropy and samples/tsm-mr use the crypto library APIs
