34af4554fb of: Introduce for_each_*_child_of_node_scoped() to automate of_node_put() handling 
To avoid issues with out of order cleanup, or ambiguity about when the
auto freed data is first instantiated, do it within the for loop definition.

The disadvantage is that the struct device_node *child variable creation
is not immediately obvious where this is used.
However, in many cases, if there is another definition of
struct device_node *child; the compiler / static analysers will notify us
that it is unused, or uninitialized.

Note that, in the vast majority of cases, the _available_ form should be
used and as code is converted to these scoped handers, we should confirm
that any cases that do not check for available have a good reason not
to.

9448e55d03 of: Add cleanup.h based auto release via __free(device_node) markings 
The recent addition of scope based cleanup support to the kernel
provides a convenient tool to reduce the chances of leaking reference
counts where of_node_put() should have been called in an error path.

This enables
	struct device_node *child __free(device_node) = NULL;

	for_each_child_of_node(np, child) {
		if (test)
			return test;
	}

with no need for a manual call of of_node_put().
A following patch will reduce the scope of the child variable to the
for loop, to avoid an issues with ordering of autocleanup, and make it
obvious when this assigned a non NULL value.

In this simple example the gains are small but there are some very
complex error handling cases buried in these loops that will be
greatly simplified by enabling early returns with out the need
for this manual of_node_put() call.

Note that there are coccinelle checks in
scripts/coccinelle/iterators/for_each_child.cocci to detect a failure
to call of_node_put(). This new approach does not cause false positives.
Longer term we may want to add scripting to check this new approach is
done correctly with no double of_node_put() calls being introduced due
to the auto cleanup. It may also be useful to script finding places
this new approach is useful.

0225bdfafd mempool: kvmalloc pool 
Add mempool_init_kvmalloc_pool() and mempool_create_kvmalloc_pool(),
which wrap kvmalloc() instead of kmalloc() - kmalloc() with a vmalloc()
fallback.

This is part of a bcachefs cleanup - dropping an internal kvpmalloc()
helper (which predates kvmalloc()) along with mempool helpers; this
replaces the bcachefs-private kvpmalloc_pool.

9d9539db86 pidfs: remove config option 
As Linus suggested this enables pidfs unconditionally. A key property to
retain is the ability to compare pidfds by inode number (cf. [1]).
That's extremely helpful just as comparing namespace file descriptors by
inode number is. They are used in a variety of scenarios where they need
to be compared, e.g., when receiving a pidfd via SO_PEERPIDFD from a
socket to trivially authenticate a the sender and various other
use-cases.

For 64bit systems this is pretty trivial to do. For 32bit it's slightly
more annoying as we discussed but we simply add a dumb ida based
allocator that gets used on 32bit. This gives the same guarantees about
inode numbers on 64bit without any overflow risk. Practically, we'll
never run into overflow issues because we're constrained by the number
of processes that can exist on 32bit and by the number of open files
that can exist on a 32bit system. On 64bit none of this matters and
things are very simple.

If 32bit also needs the uniqueness guarantee they can simply parse the
contents of /proc/<pid>/fd/<nr>. The uniqueness guarantees have a
variety of use-cases. One of the most obvious ones is that they will
make pidfiles (or "pidfdfiles", I guess) reliable as the unique
identifier can be placed into there that won't be reycled. Also a
frequent request.

Note, I took the chance and simplified path_from_stashed() even further.
Instead of passing the inode number explicitly to path_from_stashed() we
let the filesystem handle that internally. So path_from_stashed() ends
up even simpler than it is now. This is also a good solution allowing
the cleanup code to be clean and consistent between 32bit and 64bit. The
cleanup path in prepare_anon_dentry() is also switched around so we put
the inode before the dentry allocation. This means we only have to call
the cleanup handler for the filesystem's inode data once and can rely
->evict_inode() otherwise.

Aside from having to have a bit of extra code for 32bit it actually ends
up a nice cleanup for path_from_stashed() imho.

Tested on both 32 and 64bit including error injection.

6c303f1af3 crypto: introduce: acomp_is_async to expose if comp drivers might sleep 
acomp's users might want to know if acomp is really async to optimize
themselves.  One typical user which can benefit from exposed async stat is
zswap.

In zswap, zsmalloc is the most commonly used allocator for (and perhaps
the only one).  For zsmalloc, we cannot sleep while we map the compressed
memory, so we copy it to a temporary buffer.  By knowing the alg won't
sleep can help zswap to avoid the need for a buffer.  This shows
noticeable improvement in load/store latency of zswap.

c087a5c324 mm: recover pud_leaf() definitions in nopmd case 
This reverts one change in commit 924bd6a8c9 ("mm/x86: drop two
unnecessary pud_leaf() definitions").

One issue with that is it broke nopmd builds for at least both arm64 and
riscv (CONFIG_PGTABLE_LEVELS=2).  The other issue is it was overlooked that
it's a common change rather than x86 specific (relevant to the commit
message of the commit).

Normally there's no need for empty definition of pXd_leaf() because of the
fallback functions, however this logic may not apply to pgtable-nopmd.h,
because that's a header that can even be used by arch *pgtable.h headers,
which can use the *_leaf() definitions _before_ the fallback functions are
defined.  Leave it there to pass PGTABLE_LEVELS=2 builds.

Pull thermal control updates from Rafael Wysocki:
 "These mostly change the thermal core in a few ways allowing thermal
  drivers to be simplified, in particular in their removal and failing
  probe handling parts that are notoriously prone to errors, and
  propagate the changes to several drivers.

  Apart from that, support for a new platform is added (Intel Lunar
  Lake-M), some bugs are fixed and some code is cleaned up, as usual.

Pull power management updates from Rafael Wysocki:
 "From the functional perspective, the most significant change here is
  the addition of support for Energy Models that can be updated
  dynamically at run time.

  There is also the addition of LZ4 compression support for hibernation,
  the new preferred core support in amd-pstate, new platforms support in
  the Intel RAPL driver, new model-specific EPP handling in intel_pstate
  and more.

  Apart from that, the cpufreq default transition delay is reduced from
  10 ms to 2 ms (along with some related adjustments), the system
  suspend statistics code undergoes a significant rework and there is a
  usual bunch of fixes and code cleanups all over.

  Specifics:

   - Allow the Energy Model to be updated dynamically (Lukasz Luba)

   - Add support for LZ4 compression algorithm to the hibernation image
     creation and loading code (Nikhil V)

   - Fix and clean up system suspend statistics collection (Rafael
     Wysocki)

   - Simplify device suspend and resume handling in the power management
     core code (Rafael Wysocki)

   - Fix PCI hibernation support description (Yiwei Lin)

   - Make hibernation take set_memory_ro() return values into account as
     appropriate (Christophe Leroy)

   - Set mem_sleep_current during kernel command line setup to avoid an
     ordering issue with handling it (Maulik Shah)

   - Fix wake IRQs handling when pm_runtime_force_suspend() is used as a
     driver's system suspend callback (Qingliang Li)

   - Simplify pm_runtime_get_if_active() usage and add a replacement for
     pm_runtime_put_autosuspend() (Sakari Ailus)

   - Add a tracepoint for runtime_status changes tracking (Vilas Bhat)

   - Fix section title markdown in the runtime PM documentation (Yiwei
     Lin)

   - Enable preferred core support in the amd-pstate cpufreq driver
     (Meng Li)

   - Fix min_perf assignment in amd_pstate_adjust_perf() and make the
     min/max limit perf values in amd-pstate always stay within the
     (highest perf, lowest perf) range (Tor Vic, Meng Li)

   - Allow intel_pstate to assign model-specific values to strings used
     in the EPP sysfs interface and make it do so on Meteor Lake
     (Srinivas Pandruvada)

   - Drop long-unused cpudata::prev_cummulative_iowait from the
     intel_pstate cpufreq driver (Jiri Slaby)

   - Prevent scaling_cur_freq from exceeding scaling_max_freq when the
     latter is an inefficient frequency (Shivnandan Kumar)

   - Change default transition delay in cpufreq to 2ms (Qais Yousef)

   - Remove references to 10ms minimum sampling rate from comments in
     the cpufreq code (Pierre Gondois)

   - Honour transition_latency over transition_delay_us in cpufreq (Qais
     Yousef)

   - Stop unregistering cpufreq cooling on CPU hot-remove (Viresh Kumar)

   - General enhancements / cleanups to ARM cpufreq drivers (tianyu2,
     Nícolas F. R. A. Prado, Erick Archer, Arnd Bergmann, Anastasia
     Belova)

   - Update cpufreq-dt-platdev to block/approve devices (Richard Acayan)

   - Make the SCMI cpufreq driver get a transition delay value from
     firmware (Pierre Gondois)

   - Prevent the haltpoll cpuidle governor from shrinking guest
     poll_limit_ns below grow_start (Parshuram Sangle)

   - Avoid potential overflow in integer multiplication when computing
     cpuidle state parameters (C Cheng)

   - Adjust MWAIT hint target C-state computation in the ACPI cpuidle
     driver and in intel_idle to return a correct value for C0 (He
     Rongguang)

   - Address multiple issues in the TPMI RAPL driver and add support for
     new platforms (Lunar Lake-M, Arrow Lake) to Intel RAPL (Zhang Rui)

   - Fix freq_qos_add_request() return value check in dtpm_cpu (Daniel
     Lezcano)

   - Fix kernel-doc for dtpm_create_hierarchy() (Yang Li)

   - Fix file leak in get_pkg_num() in x86_energy_perf_policy (Samasth
     Norway Ananda)

   - Fix cpupower-frequency-info.1 man page typo (Jan Kratochvil)

   - Fix a couple of warnings in the OPP core code related to W=1 builds
     (Viresh Kumar)

   - Move dev_pm_opp_{init|free}_cpufreq_table() to pm_opp.h (Viresh
     Kumar)

   - Extend dev_pm_opp_data with turbo support (Sibi Sankar)

69afef4af4 gpio updates for v6.9 
Serialization rework:
 - use SRCU to serialize access to the global GPIO device list, to GPIO device
   structs themselves and to GPIO descriptors
 - make the GPIO subsystem resilient to the GPIO providers being unbound while
   the API calls are in progress
 - don't dereference the SRCU-protected chip pointer if the information we need
   can be obtained from the GPIO device structure
 - move some of the information contained in struct gpio_chip to struct
   gpio_device to further reduce the need to dereference the former
 - pass the GPIO device struct instead of the GPIO chip to sysfs callback to,
   again, reduce the need for accessing the latter
 - get GPIO descriptors from the GPIO device, not from the chip for the same
   reason
 - allow for mostly lockless operation of the GPIO driver API: assure
   consistency with SRCU and atomic operations
 - remove the global GPIO spinlock
 - remove the character device RW semaphore
 
 Core GPIOLIB:
 - constify pointers in GPIO API where applicable
 - unify the GPIO counting APIs for ACPI and OF
 - provide a macro for iterating over all GPIOs, not only the ones that are
   requested
 - remove leftover typedefs
 - pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for
   improved logging
 - constify the GPIO bus type
 - don't warn about removing GPIO chips with descriptors still held by users as
   we can now handle this situation gracefully
 - remove unused logging helpers
 - unexport functions that are only used internally in the GPIO subsystem
 - set the device type (assign the relevant struct device_type) for GPIO devices
 
 New drivers:
 - add the ChromeOS EC GPIO driver
 
 Driver improvements:
 - allow building gpio-vf610 with COMPILE_TEST as well as disabling it in
   menuconfig (before it was always built for i.MX cofigs)
 - count the number of EICs using the device properties instead of hard-coding
   it in gpio-eic-sprd
 - improve the device naming, extend the debugfs output and add lockdep asserts
   to gpio-sim
 
 DT bindings:
 - document the 'label' property for gpio-pca9570
 - convert aspeed,ast2400-gpio bindings to DT schema
 - disallow unevaluated properties for gpio-mvebu
 - document a new model in renesas,rcar-gpio
 
 Documentation:
 - improve the character device kerneldocs in user-space headers
 - add proper documentation for the character device uAPI (both v1 and v2)
 - move the sysfs and gpio-mockup docs into the "obsolete" section
 - improve naming consistency for GPIO terms
 - clarify the line values description for sysfs
 - minor docs improvements
 - improve the driver API contract for setting GPIO direction
 - mark unsafe APIs as deprecated in kerneldocs and suggest replacements
 
 Other:
 - remove an obsolete test from selftests

Merge tag 'gpio-updates-for-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "The biggest feature is the locking overhaul. Up until now the
  synchronization in the GPIO subsystem was broken. There was a single
  spinlock "protecting" multiple data structures but doing it wrong (as
  evidenced by several places where it would be released when a sleeping
  function was called and then reacquired without checking the protected
  state).

  We tried to use an RW semaphore before but the main issue with GPIO is
  that we have drivers implementing the interfaces in both sleeping and
  non-sleeping ways as well as user-facing interfaces that can be called
  both from process as well as atomic contexts. Both ends converge in
  the same code paths that can use neither spinlocks nor mutexes. The
  only reasonable way out is to use SRCU and go mostly lockless. To that
  end: we add several SRCU structs in relevant places and use them to
  assure consistency between API calls together with atomic reads and
  writes of GPIO descriptor flags where it makes sense.

  This code has spent several weeks in next and has received several
  fixes in the first week or two after which it stabilized nicely. The
  GPIO subsystem is now resilient to providers being suddenly unbound.
  We managed to also remove the existing character device RW semaphore
  and the obsolete global spinlock.

  Other than the locking rework we have one new driver (for Chromebook
  EC), much appreciated documentation improvements from Kent and the
  regular driver improvements, DT-bindings updates and GPIOLIB core
  tweaks.

  Serialization rework:
   - use SRCU to serialize access to the global GPIO device list, to
     GPIO device structs themselves and to GPIO descriptors
   - make the GPIO subsystem resilient to the GPIO providers being
     unbound while the API calls are in progress
   - don't dereference the SRCU-protected chip pointer if the
     information we need can be obtained from the GPIO device structure
   - move some of the information contained in struct gpio_chip to
     struct gpio_device to further reduce the need to dereference the
     former
   - pass the GPIO device struct instead of the GPIO chip to sysfs
     callback to, again, reduce the need for accessing the latter
   - get GPIO descriptors from the GPIO device, not from the chip for
     the same reason
   - allow for mostly lockless operation of the GPIO driver API: assure
     consistency with SRCU and atomic operations
   - remove the global GPIO spinlock
   - remove the character device RW semaphore

  Core GPIOLIB:
   - constify pointers in GPIO API where applicable
   - unify the GPIO counting APIs for ACPI and OF
   - provide a macro for iterating over all GPIOs, not only the ones
     that are requested
   - remove leftover typedefs
   - pass the consumer device to GPIO core in
     devm_fwnode_gpiod_get_index() for improved logging
   - constify the GPIO bus type
   - don't warn about removing GPIO chips with descriptors still held by
     users as we can now handle this situation gracefully
   - remove unused logging helpers
   - unexport functions that are only used internally in the GPIO
     subsystem
   - set the device type (assign the relevant struct device_type) for
     GPIO devices

  New drivers:
   - add the ChromeOS EC GPIO driver

  Driver improvements:
   - allow building gpio-vf610 with COMPILE_TEST as well as disabling it
     in menuconfig (before it was always built for i.MX cofigs)
   - count the number of EICs using the device properties instead of
     hard-coding it in gpio-eic-sprd
   - improve the device naming, extend the debugfs output and add
     lockdep asserts to gpio-sim

  DT bindings:
   - document the 'label' property for gpio-pca9570
   - convert aspeed,ast2400-gpio bindings to DT schema
   - disallow unevaluated properties for gpio-mvebu
   - document a new model in renesas,rcar-gpio

  Documentation:
   - improve the character device kerneldocs in user-space headers
   - add proper documentation for the character device uAPI (both v1 and v2)
   - move the sysfs and gpio-mockup docs into the "obsolete" section
   - improve naming consistency for GPIO terms
   - clarify the line values description for sysfs
   - minor docs improvements
   - improve the driver API contract for setting GPIO direction
   - mark unsafe APIs as deprecated in kerneldocs and suggest
     replacements

  Other:
   - remove an obsolete test from selftests"

6cdebf62a1 spi: Updates for v6.9 
This release sees some exciting changes from David Lechner which
 implements some optimisations that have been talked about for a long
 time which allows client drivers to pre-prepare SPI messages for
 repeated or low latency use.  This lets us move work out of latency
 sensitive paths and avoid repeating work for frequently performed
 operations.  As well as being useful in itself this will also be used in
 future to allow controllers to directly trigger SPI operations (eg, from
 interrupts).
 
 Otherwise this release has mostly been focused on cleanups, plus a
 couple of new devices:
 
  - Support for pre-optimising messages.
  - A big set of updates from Uwe Kleine-König moving drivers to use APIs
    with more modern terminology for controllers.
  - Major overhaul of the s3c64xx driver.
  - Support for Google GS101 and Samsung Exynos850.

The .get_modes() callback is supposed to return the number of modes,
never a negative error code. If a negative value is returned, it'll just
be interpreted as a negative count, and added to previous calculations.

Document the rules, but handle the negative values gracefully with an

c6c3187d66 lib/firmware_table: Provide buffer length argument to cdat_table_parse() 
There exist card implementations with a CDAT table using a fixed size
buffer, but with entries filled in that do not fill the whole table
length size. Then, the last entry in the CDAT table may not mark the
end of the CDAT table buffer specified by the length field in the CDAT
header. It can be shorter with trailing unused (zero'ed) data. The
actual table length is determined while reading all CDAT entries of
the table with DOE.

If the table is greater than expected (containing zero'ed trailing
data), the CDAT parser fails with:

 [   48.691717] Malformed DSMAS table length: (24:0)
 [   48.702084] [CDAT:0x00] Invalid zero length
 [   48.711460] cxl_port endpoint1: Failed to parse CDAT: -22

In addition, a check of the table buffer length is missing to prevent
an out-of-bound access then parsing the CDAT table.

Hardening code against device returning borked table. Fix that by
providing an optional buffer length argument to
acpi_parse_entries_array() that can be used by cdat_table_parse() to
propagate the buffer size down to its users to check the buffer
length. This also prevents a possible out-of-bound access mentioned.

Add a check to warn about a malformed CDAT table length.

12fb28ea6b EINJ: Add CXL error type support 
Move CXL protocol error types from einj.c (now einj-core.c) to einj-cxl.c.
einj-cxl.c implements the necessary handling for CXL protocol error
injection and exposes an API for the CXL core to use said functionality,
while also allowing the EINJ module to be built without CXL support.
Because CXL error types targeting CXL 1.0/1.1 ports require special
handling, only allow them to be injected through the new cxl debugfs
interface (next commit) and return an error when attempting to inject
through the legacy interface.

 "Improve the behavior during panic. The issues were found when testing

   - pr_flush() has to wait for the last reserved record instead of the

     when generated by more CPUs in parallel.

   - Ignore non-finalized records during panic(). Messages printed on

     might never be finalized when the CPUs get stopped.

   - Block new printk() calls on non-panic CPUs completely. Backtraces
     are printed before entering the panic mode. Later messages would
     just mess information printed by the panic CPU.

   - Do not take console_lock in console_flush_on_panic() at all. The

Yes, yes, I know the slab people were planning on going slow and letting
every subsystem fight this thing on their own.  But let's just rip off
the band-aid and get it over and done with.  I don't want to see a
number of unnecessary pull requests just to get rid of a flag that no
longer has any meaning.

This was mainly done with a couple of 'sed' scripts and then some manual
cleanup of the end result.

Pull slab updates from Vlastimil Babka:

 - Freelist loading optimization (Chengming Zhou)

   When the per-cpu slab is depleted and a new one loaded from the cpu
   partial list, optimize the loading to avoid an irq enable/disable
   cycle. This results in a 3.5% performance improvement on the "perf
   bench sched messaging" test.

 - Kernel boot parameters cleanup after SLAB removal (Xiongwei Song)

   Due to two different main slab implementations we've had boot
   parameters prefixed either slab_ and slub_ with some later becoming
   an alias as both implementations gained the same functionality (i.e.
   slab_nomerge vs slub_nomerge). In order to eventually get rid of the
   implementation-specific names, the canonical and documented
   parameters are now all prefixed slab_ and the slub_ variants become
   deprecated but still working aliases.

 - SLAB_ kmem_cache creation flags cleanup (Vlastimil Babka)

   The flags had hardcoded #define values which became tedious and
   error-prone when adding new ones. Assign the values via an enum that
   takes care of providing unique bit numbers. Also deprecate
   SLAB_MEM_SPREAD which was only used by SLAB, so it's a no-op since
   SLAB removal. Assign it an explicit zero value. The removals of the
   flag usage are handled independently in the respective subsystems,
   with a final removal of any leftover usage planned for the next
   release.

 - Misc cleanups and fixes (Chengming Zhou, Xiaolei Wang, Zheng Yejian)

   Includes removal of unused code or function parameters and a fix of a
   memleak.

Merge tag 'lsm-pr-20240312' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull lsm updates from Paul Moore:

 - Promote IMA/EVM to a proper LSM

   This is the bulk of the diffstat, and the source of all the changes
   in the VFS code. Prior to the start of the LSM stacking work it was
   important that IMA/EVM were separate from the rest of the LSMs,
   complete with their own hooks, infrastructure, etc. as it was the
   only way to enable IMA/EVM at the same time as a LSM.

   However, now that the bulk of the LSM infrastructure supports
   multiple simultaneous LSMs, we can simplify things greatly by
   bringing IMA/EVM into the LSM infrastructure as proper LSMs. This is
   something I've wanted to see happen for quite some time and Roberto
   was kind enough to put in the work to make it happen.

 - Use the LSM hook default values to simplify the call_int_hook() macro

   Previously the call_int_hook() macro required callers to supply a
   default return value, despite a default value being specified when
   the LSM hook was defined.

   This simplifies the macro by using the defined default return value
   which makes life easier for callers and should also reduce the number
   of return value bugs in the future (we've had a few pop up recently,
   hence this work).

 - Use the KMEM_CACHE() macro instead of kmem_cache_create()

   The guidance appears to be to use the KMEM_CACHE() macro when
   possible and there is no reason why we can't use the macro, so let's
   use it.

 - Fix a number of comment typos in the LSM hook comment blocks

   Not much to say here, we fixed some questionable grammar decisions in
   the LSM hook comment blocks.

* tag 'lsm-pr-20240312' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (28 commits)

6a8dbd71a7 Revert "crypto: remove CONFIG_CRYPTO_STATS" 
This reverts commit 2beb81fbf0.

While removing CONFIG_CRYPTO_STATS is a worthy goal, this also
removed unrelated infrastructure such as crypto_comp_alg_common.

9f0c4a46be f2fs: fix to truncate meta inode pages forcely 
Below race case can cause data corruption:

Thread A				GC thread
					- gc_data_segment
					 - ra_data_block
					  - locked meta_inode page
- f2fs_inplace_write_data
 - invalidate_mapping_pages
 : fail to invalidate meta_inode page
   due to lock failure or dirty|writeback
   status
 - f2fs_submit_page_bio
 : write last dirty data to old blkaddr
					 - move_data_block
					  - load old data from meta_inode page
					  - f2fs_submit_page_write
					  : write old data to new blkaddr

Because invalidate_mapping_pages() will skip invalidating page which
has unclear status including locked, dirty, writeback and so on, so
we need to use truncate_inode_pages_range() instead of
invalidate_mapping_pages() to make sure meta_inode page will be dropped.

Fixes: 6aa58d8ad2 ("f2fs: readahead encrypted block during GC")
Fixes: e3b49ea368 ("f2fs: invalidate META_MAPPING before IPU/DIO write")

9187210eee Networking changes for 6.9. 
Core & protocols
 ----------------
 
  - Large effort by Eric to lower rtnl_lock pressure and remove locks:
 
    - Make commonly used parts of rtnetlink (address, route dumps etc.)
      lockless, protected by RCU instead of rtnl_lock.
 
    - Add a netns exit callback which already holds rtnl_lock,
      allowing netns exit to take rtnl_lock once in the core
      instead of once for each driver / callback.
 
    - Remove locks / serialization in the socket diag interface.
 
    - Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
 
    - Remove the dev_base_lock, depend on RCU where necessary.
 
  - Support busy polling on a per-epoll context basis. Poll length
    and budget parameters can be set independently of system defaults.
 
  - Introduce struct net_hotdata, to make sure read-mostly global config
    variables fit in as few cache lines as possible.
 
  - Add optional per-nexthop statistics to ease monitoring / debug
    of ECMP imbalance problems.
 
  - Support TCP_NOTSENT_LOWAT in MPTCP.
 
  - Ensure that IPv6 temporary addresses' preferred lifetimes are long
    enough, compared to other configured lifetimes, and at least 2 sec.
 
  - Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
 
  - Add support for the independent control state machine for bonding
    per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
    control state machine.
 
  - Add "network ID" to MCTP socket APIs to support hosts with multiple
    disjoint MCTP networks.
 
  - Re-use the mono_delivery_time skbuff bit for packets which user
    space wants to be sent at a specified time. Maintain the timing
    information while traversing veth links, bridge etc.
 
  - Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
 
  - Simplify many places iterating over netdevs by using an xarray
    instead of a hash table walk (hash table remains in place, for
    use on fastpaths).
 
  - Speed up scanning for expired routes by keeping a dedicated list.
 
  - Speed up "generic" XDP by trying harder to avoid large allocations.
 
  - Support attaching arbitrary metadata to netconsole messages.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
    VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena).
 
  - Rework selftest harness to enable the use of the full range of
    ksft exit code (pass, fail, skip, xfail, xpass).
 
 Netfilter
 ---------
 
  - Allow userspace to define a table that is exclusively owned by a daemon
    (via netlink socket aliveness) without auto-removing this table when
    the userspace program exits. Such table gets marked as orphaned and
    a restarting management daemon can re-attach/regain ownership.
 
  - Speed up element insertions to nftables' concatenated-ranges set type.
    Compact a few related data structures.
 
 BPF
 ---
 
  - Add BPF token support for delegating a subset of BPF subsystem
    functionality from privileged system-wide daemons such as systemd
    through special mount options for userns-bound BPF fs to a trusted
    & unprivileged application.
 
  - Introduce bpf_arena which is sparse shared memory region between BPF
    program and user space where structures inside the arena can have
    pointers to other areas of the arena, and pointers work seamlessly
    for both user-space programs and BPF programs.
 
  - Introduce may_goto instruction that is a contract between the verifier
    and the program. The verifier allows the program to loop assuming it's
    behaving well, but reserves the right to terminate it.
 
  - Extend the BPF verifier to enable static subprog calls in spin lock
    critical sections.
 
  - Support registration of struct_ops types from modules which helps
    projects like fuse-bpf that seeks to implement a new struct_ops type.
 
  - Add support for retrieval of cookies for perf/kprobe multi links.
 
  - Support arbitrary TCP SYN cookie generation / validation in the TC
    layer with BPF to allow creating SYN flood handling in BPF firewalls.
 
  - Add code generation to inline the bpf_kptr_xchg() helper which
    improves performance when stashing/popping the allocated BPF objects.
 
 Wireless
 --------
 
  - Add SPP (signaling and payload protected) AMSDU support.
 
  - Support wider bandwidth OFDMA, as required for EHT operation.
 
 Driver API
 ----------
 
  - Major overhaul of the Energy Efficient Ethernet internals to support
    new link modes (2.5GE, 5GE), share more code between drivers
    (especially those using phylib), and encourage more uniform behavior.
    Convert and clean up drivers.
 
  - Define an API for querying per netdev queue statistics from drivers.
 
  - IPSec: account in global stats for fully offloaded sessions.
 
  - Create a concept of Ethernet PHY Packages at the Device Tree level,
    to allow parameterizing the existing PHY package code.
 
  - Enable Rx hashing (RSS) on GTP protocol fields.
 
 Misc
 ----
 
  - Improvements and refactoring all over networking selftests.
 
  - Create uniform module aliases for TC classifiers, actions,
    and packet schedulers to simplify creating modprobe policies.
 
  - Address all missing MODULE_DESCRIPTION() warnings in networking.
 
  - Extend the Netlink descriptions in YAML to cover message encapsulation
    or "Netlink polymorphism", where interpretation of nested attributes
    depends on link type, classifier type or some other "class type".

debdce20c4 cxl/region: Deal with numa nodes not enumerated by SRAT 
For the numa nodes that are not created by SRAT, no memory_target is
allocated and is not managed by the HMAT_REPORTING code. Therefore
hmat_callback() memory hotplug notifier will exit early on those NUMA
nodes. The CXL memory hotplug notifier will need to call
node_set_perf_attrs() directly in order to setup the access sysfs
attributes.

In acpi_numa_init(), the last proximity domain (pxm) id created by SRAT is
stored. Add a helper function acpi_node_backed_by_real_pxm() in order to
check if a NUMA node id is defined by SRAT or created by CFMWS.

node_set_perf_attrs() symbol is exported to allow update of perf attribs
for a node. The sysfs path of
/sys/devices/system/node/nodeX/access0/initiators/* is created by
node_set_perf_attrs() for the various attributes where nodeX is matched
to the NUMA node of the CXL region.

Pull hardening updates from Kees Cook:
 "As is pretty normal for this tree, there are changes all over the
  place, especially for small fixes, selftest improvements, and improved
  macro usability.

  Some header changes ended up landing via this tree as they depended on
  the string header cleanups. Also, a notable set of changes is the work
  for the reintroduction of the UBSAN signed integer overflow sanitizer
  so that we can continue to make improvements on the compiler side to
  make this sanitizer a more viable future security hardening option.

     Shevchenko)

a01c9fe323 NFSD 6.9 Release Notes 
The bulk of the patches for this release are optimizations, code
 clean-ups, and minor bug fixes.
 
 One new feature to mention is that NFSD administrators now have the
 ability to revoke NFSv4 open and lock state. NFSD's NFSv3 support
 has had this capability for some time.
 
 As always I am grateful to NFSD contributors, reviewers, and
 testers.
