Merge tag 'nfsd-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux
Pull nfsd updates from Chuck Lever: "The marquee feature for this release is that the limit on the maximum rsize and wsize has been raised to 4MB. The default remains at 1MB, but risk-seeking administrators now have the ability to try larger I/O sizes with NFS clients that support them. Eventually the default setting will be increased when we have confidence that this change will not have negative impact. With v6.16, NFSD now has its own debugfs file system where we can add experimental features and make them available outside of our development community without impacting production deployments. The first experimental setting added is one that makes all NFS READ operations use vfs_iter_read() instead of the NFSD splice actor. The plan is to eventually retire the splice actor, as that will enable a number of new capabilities such as the use of struct bio_vec from the top to the bottom of the NFSD stack. Jeff Layton contributed a number of observability improvements. The use of dprintk() in a number of high-traffic code paths has been replaced with static trace points. This release sees the continuation of efforts to harden the NFSv4.2 COPY operation. Soon, the restriction on async COPY operations can be lifted. Many thanks to the contributors, reviewers, testers, and bug reporters who participated during the v6.16 development cycle" * tag 'nfsd-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux: (60 commits) xdrgen: Fix code generated for counted arrays SUNRPC: Bump the maximum payload size for the server NFSD: Add a "default" block size NFSD: Remove NFSSVC_MAXBLKSIZE_V2 macro NFSD: Remove NFSD_BUFSIZE sunrpc: Remove the RPCSVC_MAXPAGES macro svcrdma: Adjust the number of entries in svc_rdma_send_ctxt::sc_pages svcrdma: Adjust the number of entries in svc_rdma_recv_ctxt::rc_pages sunrpc: Adjust size of socket's receive page array dynamically SUNRPC: Remove svc_rqst :: rq_vec SUNRPC: Remove svc_fill_write_vector() NFSD: Use rqstp->rq_bvec in nfsd_iter_write() SUNRPC: Export xdr_buf_to_bvec() NFSD: De-duplicate the svc_fill_write_vector() call sites NFSD: Use rqstp->rq_bvec in nfsd_iter_read() sunrpc: Replace the rq_bvec array with dynamically-allocated memory sunrpc: Replace the rq_pages array with dynamically-allocated memory sunrpc: Remove backchannel check in svc_init_buffer() sunrpc: Add a helper to derive maxpages from sv_max_mesg svcrdma: Reduce the number of rdma_rw contexts per-QP ... |

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with

abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.

Pull audit updates from Paul Moore: - Always record AUDIT_ANOM events when auditing is enabled. Prior to this patch we only recorded AUDIT_ANOM events if auditing was enabled and the admin/distro had explicitly configured audit beyond the defaults.

Merge tag 'selinux-pr-20250527' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux updates from Paul Moore: - Reduce the SELinux impact on path walks. Add a small directory access cache to the per-task SELinux state. This cache allows SELinux to cache the most recently used directory access decisions in order to avoid repeatedly querying the AVC on path walks where the majority of the directories have similar security contexts/labels. My performance measurements are crude, but prior to this patch the time spent in SELinux code on a 'make allmodconfig' run was 103% that of __d_lookup_rcu(), and with this patch the time spent in SELinux code dropped to 63% of __d_lookup_rcu(), a ~40% improvement. Additional improvments can be expected in the future, but those will require additional SELinux policy/toolchain support. - Add support for wildcards in genfscon policy statements. This patch allows for wildcards in the genfscon patch matching logic as opposed to the prefix matching that was used prior to this change. Adding wilcard support allows for more expressive and efficient path matching in the policy which is especially helpful for sysfs, and has resulted in a ~15% boot time reduction in Android. SELinux policies can opt into wilcard matching by using the "genfs_seclabel_wildcard" policy capability. - Unify the error/OOM handling of the SELinux network caches. A failure to allocate memory for the SELinux network caches isn't fatal as the object label can still be safely returned to the caller, it simply means that we cannot add the new data to the cache, at least temporarily. This patch corrects this behavior for the InfiniBand cache and does some minor cleanup. - Minor improvements around constification, 'likely' annotations, and removal of bogus comments. * tag 'selinux-pr-20250527' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: fix the kdoc header for task_avdcache_update selinux: remove a duplicated include selinux: reduce path walk overhead selinux: support wildcard match in genfscon selinux: drop copy-paste comment selinux: unify OOM handling in network hashtables selinux: add likely hints for fast paths selinux: contify network namespace pointer selinux: constify network address pointer |

Pull integrity updates from Mimi Zohar:
"Carrying the IMA measurement list across kexec is not a new feature,
but is updated to address a couple of issues:
- Carrying the IMA measurement list across kexec required knowing
apriori all the file measurements between the "kexec load" and
"kexec execute" in order to measure them before the "kexec load".
Any delay between the "kexec load" and "kexec exec" exacerbated the
problem.
- Any file measurements post "kexec load" were not carried across
kexec, resulting in the measurement list being out of sync with the
TPM PCR.
With these changes, the buffer for the IMA measurement list is still
allocated at "kexec load", but copying the IMA measurement list is
deferred to after quiescing the TPM.

However, this turned out to not scale very well especially with memcg using rstat for internal operations which made memcg stat read and flush patterns substantially different from other controllers. JP Kobryn split the rstat tree per controller. - cgroup BPF support was hooking into cgroup init/exit paths directly. Convert them to use a notifier chain instead so that other usages can be added easily. The two of the patches which implement this are mislabeled as belonging to sched_ext instead of cgroup.

Pull power management updates from Rafael Wysocki:
"Once again, the changes are dominated by cpufreq updates, but this
time the majority of them are cpufreq core changes, mostly related to
the introduction of policy locking guards and __free() usage, and
fixes related to boost handling.
Still, there is also a significant update of the intel_pstate driver
making it register an energy model when running on a hybrid platform
which is used for enabling energy-aware scheduling (EAS) if the driver
operates in the passive mode (and schedutil is used as the cpufreq
governor for all CPUs which is the passive mode default).
There are some amd-pstate driver updates too, for a good measure,
including the "Requested CPU Min frequency" BIOS option support and
new online/offline callbacks.
In the cpuidle space, the most significant change is the addition of a
C1 demotion on/off sysfs knob to intel_idle which should help some
users to configure their systems more precisely. There is also the
conversion of the PSCI cpuidle driver to a faux device one and there
are two small updates of cpuidle governors.
Device power management is also modified quite a bit, especially the
handling of devices with asynchronous suspend and resume enabled
during system transitions. They are now going to be handled more
asynchronously during suspend transitions and somewhat less
aggressively during resume transitions.
Apart from the above, the operating performance points (OPP) library
is now going to use mutex locking guards and scope-based cleanup
helpers and there is the usual bunch of assorted fixes and code
cleanups.
Specifics:
- Fix potential division-by-zero error in em_compute_costs() (Yaxiong
Tian)
- Fix typos in energy model documentation and example driver code
(Moon Hee Lee, Atul Kumar Pant)
- Rearrange the energy model management code and add a new function
for adjusting a CPU energy model after adjusting the capacity of
the given CPU to it (Rafael Wysocki)
- Refactor cpufreq_online(), add and use cpufreq policy locking
guards, use __free() in policy reference counting, and clean up
core cpufreq code on top of that (Rafael Wysocki)

Kumar)
- Fix des_perf clamping with max_perf in amd_pstate_update()
(Dhananjay Ugwekar)

rename and use the existing amd_pstate_epp callbacks in it
(Dhananjay Ugwekar)
- Add support for the "Requested CPU Min frequency" BIOS option to
the amd-pstate driver (Dhananjay Ugwekar)
- Reset amd-pstate driver mode after running selftests (Swapnil
Sapkal)
- Avoid shadowing ret in amd_pstate_ut_check_driver() (Nathan
Chancellor)
- Add helper for governor checks to the schedutil cpufreq governor
and move cpufreq-specific EAS checks to cpufreq (Rafael Wysocki)
- Populate the cpu_capacity sysfs entries from the intel_pstate
driver after registering asym capacity support (Ricardo Neri)
- Add support for enabling Energy-aware scheduling (EAS) to the
intel_pstate driver when operating in the passive mode on a hybrid
platform (Rafael Wysocki)
- Drop redundant cpus_read_lock() from store_local_boost() in the
cpufreq core (Seyediman Seyedarab)
- Replace sscanf() with kstrtouint() in the cpufreq code and use a
symbol instead of a raw number in it (Bowen Yu)
- Add support for autonomous CPU performance state selection to the
CPPC cpufreq driver (Lifeng Zheng)
- OPP: Add dev_pm_opp_set_level() (Praveen Talari)
- Introduce scope-based cleanup headers and mutex locking guards in
OPP core (Viresh Kumar)

Bityutskiy)
- Fix typos in two comments in the teo cpuidle governor (Atul Kumar

- Add new devm_ functions for enabling runtime PM and runtime PM
reference counting (Bence Csókás)
- Remove size arguments from strscpy() calls in the hibernation core
code (Thorsten Blum)
- Adjust the handling of devices with asynchronous suspend enabled
during system suspend and resume to start resuming them immediately
after resuming their parents and to start suspending such a device
immediately after suspending its first child (Rafael Wysocki)
- Adjust messages printed during tasks freezing to avoid using
pr_cont() (Andrew Sayers, Paul Menzel)
- Clean up unnecessary usage of !! in pm_print_times_init() (Zihuan

Merge tag 'gpio-updates-for-v6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We have three new drivers, some refactoring in the GPIO core, lots of
various changes across many drivers, new configfs interface for the
virtual gpio-aggregator module and DT-bindings updates.
The treewide conversion of GPIO drivers to using the new value setter
callbacks is ongoing with another round of GPIO drivers updated. You
will also see these commits coming in from other subsystems as with
the relevant changes merged into mainline last cycle, I've started
converting GPIO providers located elsewhere than drivers/gpio/.
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where
applicable which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which
will take off the burden from GPIO drivers of checking this down
the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter
callbacks
- convert more drivers to making the irq_chip immutable as is
recommended by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built
with COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that
makes the setup easier for user-space than the existing
driver-level sysfs attributes and also adds more advanced
configuration features (such as referring to aggregated lines by
their original names or modifying their names as exposed by the
aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the
global GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600
(new drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents
Misc:
- TODO list updates"

Remove legacy 'cc-disable-warning' use from the generic build scripts
This just converts the 'cc-disable-warning' uses in the generic makefile extrawarn script to use the plain 'cc-option' form instead. Partly to clean things up, and partly just to have the new form get some proper test coverage. I'll leave the various random other uses of 'cc-disable-warning' alone and let subsystem maintainers decide if they want to convert to the new unified model.

Merge tag 'docs-6.16' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"A moderately busy cycle for documentation this time around:
- The most significant change is the replacement of the old
kernel-doc script (a monstrous collection of Perl regexes that
predates the Git era) with a Python reimplementation. That, too, is
a horrifying collection of regexes, but in a much cleaner and more
maintainable structure that integrates far better with the Sphinx
build system.
This change has been in linux-next for the full 6.15 cycle; the
small number of problems that turned up have been addressed,
seemingly to everybody's satisfaction. The Perl kernel-doc script
remains in tree (as scripts/kernel-doc.pl) and can be used with a
command-line option if need be. Unless some reason to keep it
around materializes, it will probably go away in 6.17.
Credit goes to Mauro Carvalho Chehab for doing all this work.

Pull x86 resource control updates from Borislav Petkov:
"Carve out the resctrl filesystem-related code into fs/resctrl/ so that
multiple architectures can share the fs API for manipulating their
respective hw resource control implementation.
This is the second step in the work towards sharing the resctrl
filesystem interface, the next one being plugging ARM's MPAM into the
aforementioned fs API"

Merge tag 'irq-msi-2025-05-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull MSI updates from Thomas Gleixner:
"Updates for the MSI subsystem (core code and PCI):
- Switch the MSI descriptor locking to lock guards
- Replace a broken and naive implementation of PCI/MSI-X control word
updates in the PCI/TPH driver with a properly serialized variant in
the PCI/MSI core code.
- Remove the MSI descriptor abuse in the SCCI/UFS/QCOM driver by
replacing the direct access to the MSI descriptors with the proper
API function calls. People will never understand that APIs exist
for a reason...
- Provide core infrastructre for the upcoming PCI endpoint library
extensions. Currently limited to ARM GICv3+, but in theory
extensible to other architectures.
- Provide a MSI domain::teardown() callback, which allows drivers to
undo the effects of the prepare() callback.
- Move the MSI domain::prepare() callback invocation to domain
creation time to avoid redundant (and in case of ARM/GIC-V3-ITS
confusing) invocations on every allocation.
In combination with the new teardown callback this removes some
ugly hacks in the GIC-V3-ITS driver, which pretended to work around
the short comings of the core code so far. With this update the
code is correct by design and implementation.
- Make the irqchip MSI library globally available, provide a MSI
parent domain creation helper and convert a bunch of (PCI/)MSI
drivers over to the modern MSI parent mechanism. This is the first
step to get rid of at least one incarnation of the three PCI/MSI
management schemes.
- The usual small cleanups and improvements"
