  support for Android ecosystem (for vendors to try out 16k page size
  with 4k-block images in their compatibility mode) as well as container
  images (so that 4k-block images can be parsed on arm64 cloud servers
  using 64k page size.)

49f4810356 NFSD 6.8 Release Notes
The bulk of the patches for this release are clean-ups and minor bug
 fixes.
 
 There is one significant revert to mention: support for RDMA Read
 operations in the server's RPC-over-RDMA transport implementation
 has been fixed so it waits for Read completion in a way that avoids
 tying up an nfsd thread. This prevents a possible DoS vector if an
 RPC-over-RDMA client should become unresponsive during RDMA Read
 operations.
 
 As always I am grateful to NFSD contributors, reviewers, and
 testers.

d8c8e595dc dlm for 6.8
This set cleans up the interface between nfs lockd and dlm, which
 is handling nfs file locking for gfs2 and ocfs2. Very basic lockd
 functionality is fixed, in which the fl owner was using the lockd
 pid instead of the owner value from nfs.

Merge tag 'afs-fix-rotation-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull afs updates from David Howells:
 "The majority of the patches are aimed at fixing and improving the AFS
  filesystem's rotation over server IP addresses, but there are also
  some fixes from Oleg Nesterov for the use of read_seqbegin_or_lock().

   - Fix fileserver probe handling so that the next round of probes
     doesn't break ongoing server/address rotation by clearing all the
     probe result tracking. This could occasionally cause the rotation
     algorithm to drop straight through, give a 'successful' result
     without actually emitting any RPC calls, leaving the reply buffer
     in an undefined state.

     Instead, detach the probe results into a separate struct and
     allocate a new one each time we start probing and update the
     pointer to it. Probes are also sent in order of address preference
     to try and improve the chance that the preferred one will complete
     first.

   - Fix server rotation so that it uses configurable address
     preferences across on the probes that have completed so far than
     ranking them by RTT as the latter doesn't necessarily give the best
     route. The preference list can be altered by writing into
     /proc/net/afs/addr_prefs.

   - Fix the handling of Read-Only (and Backup) volume callbacks as
     there is one per volume, not one per file, so if someone performs a
     command that, say, offlines the volume but doesn't change it, when
     it comes back online we don't spam the server with a status fetch
     for every vnode we're using. Instead, check the Creation timestamp
     in the VolSync record when prompted by a callback break.

   - Handle volume regression (ie. a RW volume being restored from a
     backup) by scrubbing all cache data for that volume. This is
     detected from the VolSync creation timestamp.

   - Adjust abort handling and abort -> error mapping to match better
     with what other AFS clients do.

   - Fix offline and busy volume state handling as they only apply to
     individual server instances and not entire volumes and the rotation
     algorithm should go and look at other servers if available. Also
     make it sleep briefly before each retry if all the volume instances
     are unavailable"

  The mount API conversion is a base for future improvements that would
  come with VFS. Metadata processing has been converted to folios, not
  yet enabling the large folios but it's one patch away once everything
  gets tested enough.

  Core changes:

   - convert extent buffers to folios:
      - direct API conversion where possible
      - performance can drop by a few percent on metadata heavy
        workloads, the folio sizes are not constant and the calculations
        add up in the item helpers
      - both regular and subpage modes
      - data cannot be converted yet, we need to port that to iomap and
        there are some other generic changes required

   - convert mount to the new API, should not be user visible:
      - options deprecated long time ago have been removed: inode_cache,
        recovery
      - the new logic that splits mount to two phases slightly changes
        timing of device scanning for multi-device filesystems
      - LSM options will now work (like for selinux)

   - convert delayed nodes radix tree to xarray, preserving the
     preload-like logic that still allows to allocate with GFP_NOFS

   - more validation of sysfs value of scrub_speed_max

   - refactor chunk map structure, reduce size and improve performance

   - extent map refactoring, smaller data structures, improved
     performance

   - reduce size of struct extent_io_tree, embedded in several
     structures

   - temporary pages used for compression are cached and attached to a
     shrinker, this may slightly improve performance

   - in zoned mode, remove redirty extent buffer tracking, zeros are
     written in case an out-of-order is detected and proper data are
     written to the actual write pointer

   - cleanups, refactoring, error message improvements, updated tests

   - verify and update branch name or tag

   - remove unwanted text"

12958e9c4c New code for 6.8:
* New features/functionality
     * Online repair
       * Reserve disk space for online repairs.
       * Fix misinteraction between the AIL and btree bulkloader because of
         which the bulk load fails to queue a buffer for writeback if it
         happens to be on the AIL list.
       * Prevent transaction reservation overflows when reaping blocks during
         online repair.
       * Whenever possible, bulkloader now copies multiple records into a
         block.
       * Support repairing of
         1. Per-AG free space, inode and refcount btrees.
 	2. Ondisk inodes.
 	3. File data and attribute fork mappings.
       * Verify the contents of
         1. Inode and data fork of realtime bitmap file.
 	2. Quota files.
     * Introduce MF_MEM_PRE_REMOVE. This will be used to notify tasks about
       a pmem device being removed.
 
   * Bug fixes
     * Fix memory leak of recovered attri intent items.
     * Fix UAF during log intent recovery.
     * Fix realtime geometry integer overflows.
     * Prevent scrub from live locking in xchk_iget.

     * Cleanup resblks interfaces.
     * Pass defer ops pointer to defer helpers instead of an enum.
     * Initialize di_crc in xfs_log_dinode to prevent KMSAN warnings.
     * Use static_assert() instead of BUILD_BUG_ON_MSG() to validate size of
       structures and structure member offsets. This is done in order to be
       able to share the code with userspace.
     * Move XFS documentation under a new directory specific to XFS.
     * Do not invoke deferred ops' ->create_done callback if the deferred
       operation does not have an intent item associated with it.

Merge tag 'pm-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
 "These add support for new processors (Sierra Forest, Grand Ridge and
  Meteor Lake) to the intel_idle driver, make intel_pstate run on
  Emerald Rapids without HWP support and adjust it to utilize EPP values
  supplied by the platform firmware, fix issues, clean up code and
  improve documentation.

  The most significant fix addresses deadlocks in the core system-wide
  resume code that occur if async_schedule_dev() attempts to run its
  argument function synchronously (for example, due to a memory
  allocation failure). It rearranges the code in question which may
  increase the system resume time in some cases, but this basically is a
  removal of a premature optimization. That optimization will be added
  back later, but properly this time.

  Specifics:

   - Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
     to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)

   - Do not enable interrupts when entering idle in the haltpoll cpuidle

Pull thermal control updates from Rafael Wysocki:
 "These add support for the D1/T113s THS controller to the sun8i driver
  and a DT-based mechanism for platforms to indicate a preference to
  reboot (instead of shutting down) on crossing a critical trip point,
  fix issues, make other improvements (in the IPA governor, the Intel
  HFI driver, the exynos driver and the thermal netlink interface among
  other places) and clean up code.

  One long-standing issue addressed here is that trip point crossing
  notifications sent to user space might be unreliable due to the
  incorrect handling of trip point hysteresis in the thermal core:
  multiple notifications might be sent for the same event or there might
  be events without any notification at all.

Pull ACPI updates from Rafael Wysocki:
 "From the new features standpoint, the most significant change here is
  the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
  device enumeration code that will allow MIPI cameras to be enumerated
  through the platform firmware on systems using ACPI.

  Also significant is the switch-over to threaded interrupt handlers for
  the ACPI SCI and the dedicated EC interrupt (on systems where the
  former is not used) which essentially allows all ACPI code to run with
  local interrupts enabled. That should improve responsiveness
  significantly on systems where multiple GPEs are enabled and the
  handling of one SCI involves many I/O address space accesses which
  previously had to be carried out in one go with disabled interrupts on
  the local CPU.

  Apart from the above, the ACPI thermal zone driver will use the
  Thermal fast Sampling Period (_TFP) object if available, which should
  allow temperature changes to be followed more accurately on some
  systems, the ACPI Notify () handlers can run on all CPUs (not just on
  CPU0), which should generally speed up the processing of events
  signaled through the ACPI SCI, and the ACPI power button driver will
  trigger wakeup key events via the input subsystem (on systems where it
  is a system wakeup device)

  In addition to that, there are the usual bunch of fixes and cleanups.

  Specifics:

   - Add CSI-2 and DisCo for Imaging support to the ACPI device
     enumeration code (Sakari Ailus, Rafael J. Wysocki)

   - Adjust the cpufreq thermal reduction algorithm in the ACPI

301940020a spi: Updates for v6.8
A moderately busy release for SPI, the main core update was the merging
 of support for multiple chip selects, used in some flash configurations.
 There were also big overhauls for the AXI SPI Engine and PL022 drivers,
 plus some new device support for ST.
 
 There's a few patches for other trees, API updates to allow the
 multiple chip select support and one of the naming modernisations
 touched a controller embedded in the USB code.
 
  - Support for multiple chip selects.
  - A big overhaul for the AXI SPI engine driver, modernising it and
    adding a bunch of new features.
  - Modernisation of the PL022 driver, fixing some issues with submitting
    messages while in atomic context in the process.
  - Many drivers were converted to use new APIs which avoid outdated
    terminology for devices and controllers.
  - Support for ST Microelectronics STM32F7 and STM32MP25, and Renesas
    RZ/Five.

da96801729 regulator: Updates for v6.8
The main updates for this release are around monitoring of regulators,
 largely for error handling purposes.  We allow the stream of regulator
 events to be seen by userspace as netlink events and allow system
 integrators to describe individual regulators as system critical with
 information on how long the system is expected to last on error.  The
 system level error handling is very much about best effort problem
 mitigation rather than providing something fully robust, the initial
 drive was to provide a mechanism for trying to avoid initiating any new
 writes to flash once we notice the power going out.
 
 Otherwise it's very quiet, mainly several new Qualcomm devices.
 
  - Support for marking regulators as system critical and providing
    information on how long the system might last with those regulators
    in a failure state, hooked into the existing critical shutdown error
    handling.
  - Optional support for generating netlink events for events, there are
    use cases for system monitoring UIs and error handling.
  - A command line option to leave unused controllable regulators
    enabled, useful for debugging.  We already only disable regulators we
    were explicitly given permission to control.
  - Support for Quacomm MP5496, PM8010 and PM8937.

Merge tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull security module updates from Paul Moore:

 - Add three new syscalls: lsm_list_modules(), lsm_get_self_attr(), and
   lsm_set_self_attr().

   The first syscall simply lists the LSMs enabled, while the second and
   third get and set the current process' LSM attributes. Yes, these
   syscalls may provide similar functionality to what can be found under
   /proc or /sys, but they were designed to support multiple,
   simultaneaous (stacked) LSMs from the start as opposed to the current
   /proc based solutions which were created at a time when only one LSM
   was allowed to be active at a given time.

   We have spent considerable time discussing ways to extend the
   existing /proc interfaces to support multiple, simultaneaous LSMs and
   even our best ideas have been far too ugly to support as a kernel
   API; after +20 years in the kernel, I felt the LSM layer had
   established itself enough to justify a handful of syscalls.

   Support amongst the individual LSM developers has been nearly
   unanimous, with a single objection coming from Tetsuo (TOMOYO) as he
   is worried that the LSM_ID_XXX token concept will make it more
   difficult for out-of-tree LSMs to survive. Several members of the LSM
   community have demonstrated the ability for out-of-tree LSMs to
   continue to exist by picking high/unused LSM_ID values as well as
   pointing out that many kernel APIs rely on integer identifiers, e.g.
   syscalls (!), but unfortunately Tetsuo's objections remain.

   My personal opinion is that while I have no interest in penalizing
   out-of-tree LSMs, I'm not going to penalize in-tree development to
   support out-of-tree development, and I view this as a necessary step
   forward to support the push for expanded LSM stacking and reduce our
   reliance on /proc and /sys which has occassionally been problematic
   for some container users. Finally, we have included the linux-api
   folks on (all?) recent revisions of the patchset and addressed all of
   their concerns.

 - Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit
   ioctls on 64-bit systems problem.

   This patch includes support for all of the existing LSMs which
   provide ioctl hooks, although it turns out only SELinux actually
   cares about the individual ioctls. It is worth noting that while
   Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this
   patch, they did both indicate they are okay with the changes.

 - Fix a potential memory leak in the CALIPSO code when IPv6 is disabled
   at boot.

   While it's good that we are fixing this, I doubt this is something
   users are seeing in the wild as you need to both disable IPv6 and
   then attempt to configure IPv6 labeled networking via
   NetLabel/CALIPSO; that just doesn't make much sense.

   Normally this would go through netdev, but Jakub asked me to take
   this patch and of all the trees I maintain, the LSM tree seemed like
   the best fit.

 - Update the LSM MAINTAINERS entry with additional information about
   our process docs, patchwork, bug reporting, etc.

   I also noticed that the Lockdown LSM is missing a dedicated
   MAINTAINERS entry so I've added that to the pull request. I've been
   working with one of the major Lockdown authors/contributors to see if
   they are willing to step up and assume a Lockdown maintainer role;
   hopefully that will happen soon, but in the meantime I'll continue to
   look after it.

 - Add a handful of mailmap entries for Serge Hallyn and myself.

Merge tag 'selinux-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:

 - Add a new SELinux initial SID, SECINITSID_INIT, to represent
   userspace processes started before the SELinux policy is loaded in
   early boot.

   Prior to this patch all processes were marked as SECINITSID_KERNEL
   before the SELinux policy was loaded, making it difficult to
   distinquish early boot userspace processes from the kernel in the
   SELinux policy.

   For most users this will be a non-issue as the policy is loaded early
   enough during boot, but for users who load their SELinux policy
   relatively late, this should make it easier to construct meaningful
   security policies.

 - Cleanups to the selinuxfs code by Al, mostly on VFS related issues
   during a policy reload.

   The commit description has more detail, but the quick summary is that
   we are replacing a disconnected directory approach with a temporary
   directory that we swapover at the end of the reload.

 - Fix an issue where the input sanity checking on socket bind()
   operations was slightly different depending on the presence of
   SELinux.

   This is caused by the placement of the LSM hooks in the generic
   socket layer as opposed to the protocol specific bind() handler where
   the protocol specific sanity checks are performed. Mickaël has
   mentioned that he is working to fix this, but in the meantime we just
   ensure that we are replicating the checks properly.

   We need to balance the placement of the LSM hooks with the number of
   LSM hooks; pushing the hooks down into the protocol layers is likely
   not the right answer.

 - Update the avc_has_perm_noaudit() prototype to better match the
   function definition.

 - Migrate from using partial_name_hash() to full_name_hash() the
   filename transition hash table.

   This improves the quality of the code and has the potential for a
   minor performance bump.

 - Consolidate some open coded SELinux access vector comparisions into a
   single new function, avtab_node_cmp(), and use that instead.

   A small, but nice win for code quality and maintainability.

 - Updated the SELinux MAINTAINERS entry with additional information
   around process, bug reporting, etc.

   We're also updating some of our "official" roles: dropping Eric Paris
   and adding Ondrej as a reviewer.

 - Cleanup the coding style crimes in security/selinux/include.

   While I'm not a fan of code churn, I am pushing for more automated
   code checks that can be done at the developer level and one of the
   obvious things to check for is coding style.

   In an effort to start from a "good" base I'm slowly working through
   our source files cleaning them up with the help of clang-format and
   good ol' fashioned human eyeballs; this has the first batch of these
   changes.

   I've been splitting the changes up per-file to help reduce the impact
   if backports are required (either for LTS or distro kernels), and I
   expect the some of the larger files, e.g. hooks.c and ss/services.c,
   will likely need to be split even further.

 - Cleanup old, outdated comments.

Merge tag 'audit-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:
 "The audit updates are fairly minor with only two patches:

   - Send an audit ACK to userspace immediately upon receiving an auditd
     registration event as opposed to waiting until the registration has
     been fully processed and the audit backlog starts filling the
     netlink buffers.

     Sending the ACK earlier, as done here, is still safe as the
     operation should not fail at the point when the ACK is done, and
     doing so helps avoid the ACK being dropped in extreme situations.

   - Update the audit MAINTAINERS entry with additional information.

     There isn't anything in this update that should be new to regular
     contributors or list subscribers, but I'm pushing to start
     documenting our processes, conventions, etc. and this seems like an
     important part of that"

Merge tag 'slab-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull slab updates from Vlastimil Babka:

 - SLUB: delayed freezing of CPU partial slabs (Chengming Zhou)

   Freezing is an operation involving double_cmpxchg() that makes a slab
   exclusive for a particular CPU. Chengming noticed that we use it also
   in situations where we are not yet installing the slab as the CPU
   slab, because freezing also indicates that the slab is not on the
   shared list. This results in redundant freeze/unfreeze operation and
   can be avoided by marking separately the shared list presence by
   reusing the PG_workingset flag.

   This approach neatly avoids the issues described in 9b1ea29bc0
   ("Revert "mm, slub: consider rest of partial list if acquire_slab()
   fails"") as we can now grab a slab from the shared list in a quick
   and guaranteed way without the cmpxchg_double() operation that
   amplifies the lock contention and can fail.

   As a result, lkp has reported 34.2% improvement of
   stress-ng.rawudp.ops_per_sec

 - SLAB removal and SLUB cleanups (Vlastimil Babka)

   The SLAB allocator has been deprecated since 6.5 and nobody has
   objected so far. We agreed at LSF/MM to wait until the next LTS,
   which is 6.6, so we should be good to go now.

   This doesn't yet erase all traces of SLAB outside of mm/ so some dead
   code, comments or documentation remain, and will be cleaned up
   gradually (some series are already in the works).

   Removing the choice of allocators has already allowed to simplify and
   optimize the code wiring up the kmalloc APIs to the SLUB
   implementation.

9f8413c4a6 cgroup: Changes for v6.8
- Yafang Shao added task_get_cgroup1() helper to enable a similar BPF helper
   so that BPF progs can be more useful on cgroup1 hierarchies. While cgroup1
   is mostly in maintenance mode, this addition is very small while having an
   outsized usefulness for users who are still on cgroup1. Yafang also
   optimized root cgroup list access by making it RCU protected in the
   process.
 
 - Waiman Long optimized rstat operation leading to substantially lower and
   more consistent lock hold time while flushing the hierarchical statistics.
   As the lock can be acquired briefly in various hot paths, this reduction
   has cascading benefits.
 
 - Waiman also improved the quality of isolation for cpuset's isolated

   This involved a couple workqueue patches which were applied directly to
   cgroup/for-6.8 rather than ping-ponged through the wq tree. This was
   because the wq code change was small and the area is usually very static
   and unlikely to cause conflicts. However, luck had it that there was a wq
   bug fix in the area during the 6.7 cycle which caused a conflict. The
   conflict is contextual but can be a bit confusing to resolve, so there is
   one merge from wq/for-6.7-fixes.

Pull cgroup updates from Tejun Heo:

 - Yafang Shao added task_get_cgroup1() helper to enable a similar BPF
   helper so that BPF progs can be more useful on cgroup1 hierarchies.
   While cgroup1 is mostly in maintenance mode, this addition is very
   small while having an outsized usefulness for users who are still on
   cgroup1. Yafang also optimized root cgroup list access by making it
   RCU protected in the process.

 - Waiman Long optimized rstat operation leading to substantially lower
   and more consistent lock hold time while flushing the hierarchical
   statistics. As the lock can be acquired briefly in various hot paths,
   this reduction has cascading benefits.

 - Waiman also improved the quality of isolation for cpuset's isolated
   partitions. CPUs which are allocated to isolated partitions are now
   excluded from running unbound work items and cpu_is_isolated() test
   which is used by vmstat and memcg to reduce interference now includes
   cpuset isolated CPUs. While it isn't there yet, the hope is
   eventually reaching parity with the isolation level provided by the
   `isolcpus` boot param but in a dynamic manner.

bfe8eb3b85 Scheduler changes for v6.8:
- Energy scheduling:
 
     - Consolidate how the max compute capacity is
       used in the scheduler and how we calculate
       the frequency for a level of utilization.
 
     - Rework interface between the scheduler and
       the schedutil governor
 
     - Simplify the util_est logic
 
  - Deadline scheduler:
 
     - Work more towards reducing SCHED_DEADLINE
       starvation of low priority tasks (e.g., SCHED_OTHER)
       tasks when higher priority tasks monopolize CPU
       cycles, via the introduction of 'deadline servers'
       (nested/2-level scheduling).
       "Fair servers" to make use of this facility are
       not introduced yet.
 
  - EEVDF:
 
     - Introduce O(1) fastpath for EEVDF task selection
 
  - NUMA balancing:
 
     - Tune the NUMA-balancing vma scanning logic some more,
       to better distribute the probability
       of a particular vma getting scanned.
 
  - Plus misc fixes, cleanups and updates.

f0a78b3e2a arm64: Update __NR_compat_syscalls for statmount/listmount
Commit d8b0f54650 ("wire up syscalls for statmount/listmount") added
two new system calls to arch/arm64/include/asm/unistd32.h but forgot to
update the __NR_compat_syscalls number, thus causing the following build
failures:

  arch/arm64/include/asm/unistd32.h:922:24: error: array index in initializer exceeds array bounds
    922 | #define __NR_statmount 457
        |                        ^~~
  arch/arm64/kernel/sys32.c:130:34: note: in definition of macro '__SYSCALL'
    130 | #define __SYSCALL(nr, sym)      [nr] = __arm64_##sym,
        |                                  ^~

Bump up the number by two to accomodate for the new system calls added.
