Pull lsm updates from Paul Moore:

 - Move the LSM framework to static calls

   This transitions the vast majority of the LSM callbacks into static
   calls. Those callbacks which haven't been converted were left as-is
   due to the general ugliness of the changes required to support the
   static call conversion; we can revisit those callbacks at a future
   date.

 - Add the Integrity Policy Enforcement (IPE) LSM

   This adds a new LSM, Integrity Policy Enforcement (IPE). There is
   plenty of documentation about IPE in this patches, so I'll refrain
   from going into too much detail here, but the basic motivation behind
   IPE is to provide a mechanism such that administrators can restrict
   execution to only those binaries which come from integrity protected
   storage, e.g. a dm-verity protected filesystem. You will notice that
   IPE requires additional LSM hooks in the initramfs, dm-verity, and
   fs-verity code, with the associated patches carrying ACK/review tags
   from the associated maintainers. We couldn't find an obvious
   maintainer for the initramfs code, but the IPE patchset has been
   widely posted over several years.

   Both Deven Bowers and Fan Wu have contributed to IPE's development
   over the past several years, with Fan Wu agreeing to serve as the IPE
   maintainer moving forward. Once IPE is accepted into your tree, I'll
   start working with Fan to ensure he has the necessary accounts, keys,
   etc. so that he can start submitting IPE pull requests to you
   directly during the next merge window.

 - Move the lifecycle management of the LSM blobs to the LSM framework

   Management of the LSM blobs (the LSM state buffers attached to
   various kernel structs, typically via a void pointer named "security"
   or similar) has been mixed, some blobs were allocated/managed by
   individual LSMs, others were managed by the LSM framework itself.

   Starting with this pull we move management of all the LSM blobs,
   minus the XFRM blob, into the framework itself, improving consistency
   across LSMs, and reducing the amount of duplicated code across LSMs.
   Due to some additional work required to migrate the XFRM blob, it has
   been left as a todo item for a later date; from a practical
   standpoint this omission should have little impact as only SELinux
   provides a XFRM LSM implementation.

 - Fix problems with the LSM's handling of F_SETOWN

   The LSM hook for the fcntl(F_SETOWN) operation had a couple of
   problems: it was racy with itself, and it was disconnected from the
   associated DAC related logic in such a way that the LSM state could
   be updated in cases where the DAC state would not. We fix both of
   these problems by moving the security_file_set_fowner() hook into the
   same section of code where the DAC attributes are updated. Not only
   does this resolve the DAC/LSM synchronization issue, but as that code
   block is protected by a lock, it also resolve the race condition.

 - Fix potential problems with the security_inode_free() LSM hook

   Due to use of RCU to protect inodes and the placement of the LSM hook
   associated with freeing the inode, there is a bit of a challenge when
   it comes to managing any LSM state associated with an inode. The VFS
   folks are not open to relocating the LSM hook so we have to get
   creative when it comes to releasing an inode's LSM state.
   Traditionally we have used a single LSM callback within the hook that
   is triggered when the inode is "marked for death", but not actually
   released due to RCU.

   Unfortunately, this causes problems for LSMs which want to take an
   action when the inode's associated LSM state is actually released; so
   we add an additional LSM callback, inode_free_security_rcu(), that is
   called when the inode's LSM state is released in the RCU free
   callback.

 - Refactor two LSM hooks to better fit the LSM return value patterns

   The vast majority of the LSM hooks follow the "return 0 on success,
   negative values on failure" pattern, however, there are a small
   handful that have unique return value behaviors which has caused
   confusion in the past and makes it difficult for the BPF verifier to
   properly vet BPF LSM programs. This includes patches to
   convert two of these"special" LSM hooks to the common 0/-ERRNO pattern.

 - Various cleanups and improvements

   A handful of patches to remove redundant code, better leverage the
   IS_ERR_OR_NULL() helper, add missing "static" markings, and do some
   minor style fixups.

Pull selinux updates from Paul Moore:

 - Ensure that both IPv4 and IPv6 connections are properly initialized

   While we always properly initialized IPv4 connections early in their
   life, we missed the necessary IPv6 change when we were adding IPv6
   support.

 - Annotate the SELinux inode revalidation function to quiet KCSAN

   KCSAN correctly identifies a race in __inode_security_revalidate()
   when we check to see if an inode's SELinux has been properly
   initialized. While KCSAN is correct, it is an intentional choice made
   for performance reasons; if necessary, we check the state a second
   time, this time with a lock held, before initializing the inode's
   state.

 - Code cleanups, simplification, etc.

   A handful of individual patches to simplify some SELinux kernel
   logic, improve return code granularity via ERR_PTR(), follow the
   guidance on using KMEM_CACHE(), and correct some minor style
   problems.

Pull audit updates from Paul Moore:

 - Fix some remaining problems with PID/TGID reporting

   When most users think about PIDs, what they are really thinking about
   is the TGID. This commit shifts the audit PID logging and filtering
   to use the TGID value which should provide a more meaningful audit
   stream and filtering experience for users.

 - Migrate to the str_enabled_disabled() helper

   Evidently we have helper functions that help ensure if we mistype
   "enabled" or "disabled" it is now caught at compile time. I guess
   we're fancy now.

Fix an upstream merge resolution issue[1].  The NETFS_SREQ_HIT_EOF flag,
and code to set it, got added via two different paths.  The original path
saw it added in the netfslib read improvements[2], but it was also added,
and slightly differently, in a fix that was committed before v6.11:

        1da29f2c
        netfs, cifs: Fix handling of short DIO read

However, the code added to smb2_readv_callback() to set the flag in didn't
get removed when the netfs read improvements series was rebased to take
account of the cifs fixes.  The proposed merge resolution[2] deleted it
rather than rebase the patches.

Fix this by removing the redundant lines.  Code to set the bit that derives
from the fix patch is still there, a few lines above in the source.

Fix an upstream merge resolution issue[1].  Prior to the netfs read
healpers, the SMB1 asynchronous read callback, cifs_readv_worker()
performed the cleanup for the operation in the network message processing
loop, potentially slowing down the processing of incoming SMB messages.

With commit a68c7486 ("cifs: Fix SMB1 readv/writev callback in the same
way as SMB2/3"), this was moved to a worker thread (as is done in the
SMB2/3 transport variant).  However, the "was_async" argument to
netfs_subreq_terminated (which was originally incorrectly "false" got
flipped to "true" - which was then incorrect because, being in a kernel
thread, it's not in an async context).

This got corrected in the sample merge[2], but Linus, not unreasonably,
switched it back to its previous value.

Note that this value tells netfslib whether or not it can run sleepable
stuff or stuff that takes a long time, such as retries and cleanups, in the
calling thread, or whether it should offload to a worker thread.

Fix this so that it is "false".  The callback to netfslib in both SMB1 and
SMB2/3 now gets offloaded from the network message thread to a separate
worker thread and thus it's fine to do the slow work in this thread.

Pull io_uring async discard support from Jens Axboe:
 "Sitting on top of both the 6.12 block and io_uring core branches,
  here's support for async discard through io_uring.

  This allows applications to issue async discards, rather than rely on
  the blocking sync ioctl discards we already have. The sync support is
  difficult to use outside of idle/cleanup periods.

  On a real (but slow) device, testing shows the following results when
  compared to sync discard:

	qd64 sync discard: 21K IOPS, lat avg 3 msec (max 21 msec)
	qd64 async discard: 76K IOPS, lat avg 845 usec (max 2.2 msec)

	qd64 sync discard: 14K IOPS, lat avg 5 msec (max 25 msec)
	qd64 async discard: 56K IOPS, lat avg 1153 usec (max 3.6 msec)

  and synthetic null_blk testing with the same queue depth and block
  size settings as above shows:

	Type    Trim size       IOPS    Lat avg (usec)  Lat Max (usec)
	==============================================================
	sync    4k               144K       444            20314

Pull erofs updates from Gao Xiang:
 "In this cycle, we add file-backed mount support, which has has been a
  strong requirement for years. It is especially useful when there are
  thousands of images running on the same host for containers and other
  sandbox use cases, unlike OS image use cases.

  Without file-backed mounts, it's hard for container runtimes to manage
  and isolate so many unnecessary virtual block devices safely and
  efficiently, therefore file-backed mounts are highly preferred. For
  EROFS users, ComposeFS [1], containerd, and Android APEXes [2] will
  directly benefit from it, and I've seen no risk in implementing it as
  a completely immutable filesystem.

  The previous experimental feature "EROFS over fscache" is now marked
  as deprecated because:

   - Fscache is no longer an independent subsystem and has been merged
     into netfs, which was somewhat unexpected when it was proposed.

   - New HSM "fanotify pre-content hooks" [3] will be landed upstream.
     These hooks will replace "EROFS over fscache" in a simpler way, as
     EROFS won't be bother with kernel caching anymore. Userspace
     programs can also manage their own caching hierarchy more flexibly.

  Once the HSM "fanotify pre-content hooks" is landed, I will remove the
  fscache backend entirely as an internal dependency cleanup. More
  backgrounds are listed in the original patchset [4].

  In addition to that, there are bugfixes and cleanups as usual.

  Summary:

   - Support file-backed mounts for containers and sandboxes

   - Mark the experimental fscache backend as deprecated

   - Handle overlapped pclusters caused by crafted images properly

   - Fix a failure path which could cause infinite loops in
     z_erofs_init_decompressor()

Pull btrfs updates from David Sterba:
 "This brings mostly refactoring, cleanups, minor performance
  optimizations and usual fixes. The folio API conversions are most
  noticeable.

  There's one less visible change that could have a high impact. The
  extent lock scope for read is reduced, not held for the entire
  operation. In the buffered read case it's left to page or inode lock,
  some direct io read synchronization is still needed.

  This used to prevent deadlocks induced by page faults during direct
  io, so there was a 4K limitation on the requests, e.g. for io_uring.
  In the future this will allow smoother integration with iomap where
  the extent read lock was a major obstacle.

  User visible changes:

   - the FSTRIM ioctl updates the processed range even after an error or
     interruption

   - cleaner thread is woken up in SYNC ioctl instead of waking the
     transaction thread that can take some delay before waking up the
     cleaner, this can speed up cleaning of deleted subvolumes

   - print an error message when opening a device fail, e.g. when it's
     unexpectedly read-only

  Core changes:

   - improved extent map handling in various ways (locking, iteration, ...)

   - new assertions and locking annotations

   - raid-stripe-tree locking fixes

   - use xarray for tracking dirty qgroup extents, switched from rb-tree

   - turn the subpage test to compile-time condition if possible (e.g.
     on x86_64 with 4K pages), this allows to skip a lot of ifs and
     remove dead code

   - more preparatory work for compression in subpage mode

  Cleanups and refactoring

   - folio API conversions, many simple cases where page is passed so
     switch it to folios

   - more subpage code refactoring, update page state bitmap processing

   - introduce auto free for btrfs_path structure, use for the simple

Pull netfs updates from Christian Brauner:
 "This contains the work to improve read/write performance for the new
  netfs library.

  The main performance enhancing changes are:

   - Define a structure, struct folio_queue, and a new iterator type,
     ITER_FOLIOQ, to hold a buffer as a replacement for ITER_XARRAY. See
     that patch for questions about naming and form.

     ITER_FOLIOQ is provided as a replacement for ITER_XARRAY. The
     problem with an xarray is that accessing it requires the use of a
     lock (typically the RCU read lock) - and this means that we can't
     supply iterate_and_advance() with a step function that might sleep
     (crypto for example) without having to drop the lock between pages.
     ITER_FOLIOQ is the iterator for a chain of folio_queue structs,
     where each folio_queue holds a small list of folios. A folio_queue
     struct is a simpler structure than xarray and is not subject to
     concurrent manipulation by the VM. folio_queue is used rather than
     a bvec[] as it can form lists of indefinite size, adding to one end
     and removing from the other on the fly.

   - Provide a copy_folio_from_iter() wrapper.

   - Make cifs RDMA support ITER_FOLIOQ.

   - Use folio queues in the write-side helpers instead of xarrays.

   - Add a function to reset the iterator in a subrequest.

   - Simplify the write-side helpers to use sheaves to skip gaps rather
     than trying to work out where gaps are.

   - In afs, make the read subrequests asynchronous, putting them into
     work items to allow the next patch to do progressive
     unlocking/reading.

   - Overhaul the read-side helpers to improve performance.

   - Fix the caching of a partial block at the end of a file.

   - Allow a store to be cancelled.

  Then some changes for cifs to make it use folio queues instead of
  xarrays for crypto bufferage:

   - Use raw iteration functions rather than manually coding iteration
     when hashing data.

   - Switch to using folio_queue for crypto buffers.

   - Remove the xarray bits.

  Make some adjustments to the /proc/fs/netfs/stats file such that:

   - All the netfs stats lines begin 'Netfs:' but change this to
     something a bit more useful.

Pull vfs mount updates from Christian Brauner:
 "Recently, we added the ability to list mounts in other mount
  namespaces and the ability to retrieve namespace file descriptors
  without having to go through procfs by deriving them from pidfds.

  This extends nsfs in two ways:

   (1) Add the ability to retrieve information about a mount namespace
       via NS_MNT_GET_INFO.

       This will return the mount namespace id and the number of mounts
       currently in the mount namespace. The number of mounts can be
       used to size the buffer that needs to be used for listmount() and
       is in general useful without having to actually iterate through
       all the mounts.

      The structure is extensible.

   (2) Add the ability to iterate through all mount namespaces over
       which the caller holds privilege returning the file descriptor
       for the next or previous mount namespace.

       To retrieve a mount namespace the caller must be privileged wrt
       to it's owning user namespace. This means that PID 1 on the host
       can list all mounts in all mount namespaces or that a container
       can list all mounts of its nested containers.

       Optionally pass a structure for NS_MNT_GET_INFO with
       NS_MNT_GET_{PREV,NEXT} to retrieve information about the mount
       namespace in one go.

  (1) and (2) can be implemented for other namespace types easily.

  Together with recent api additions this means one can iterate through
  all mounts in all mount namespaces without ever touching procfs.

  The commit message in 49224a34 ('Merge patch series "nsfs: iterate
  through mount namespaces"') contains example code how to do this"

  fs: allow mount namespace fd

Pull procfs updates from Christian Brauner:
 "This contains the following changes for procfs:

   - Add config options and parameters to block forcing memory writes.

     This adds a Kconfig option and boot param to allow removing the
     FOLL_FORCE flag from /proc/<pid>/mem write calls as this can be
     used in various attacks.

     The traditional forcing behavior is kept as default because it can
     break GDB and some other use cases.

     This is the simpler version that you had requested.

   - Restrict overmounting of ephemeral entities.

     It is currently possible to mount on top of various ephemeral
     entities in procfs. This specifically includes magic links. To
     recap, magic links are links of the form /proc/<pid>/fd/<nr>. They
     serve as references to a target file and during path lookup they
     cause a jump to the target path. Such magic links disappear if the
     corresponding file descriptor is closed.

     Currently it is possible to overmount such magic links. This is
     mostly interesting for an attacker that wants to somehow trick a
     process into e.g., reopening something that it didn't intend to
     reopen or to hide a malicious file descriptor.

     But also it risks leaking mounts for long-running processes. When
     overmounting a magic link like above, the mount will not be
     detached when the file descriptor is closed. Only the target
     mountpoint will disappear. Which has the consequence of making it
     impossible to unmount that mount afterwards. So the mount will
     stick around until the process exits and the /proc/<pid>/ directory
     is cleaned up during proc_flush_pid() when the dentries are pruned
     and invalidated.

     That in turn means it's possible for a program to accidentally leak
     mounts and it's also possible to make a task leak mounts without
     it's knowledge if the attacker just keeps overmounting things under
     /proc/<pid>/fd/<nr>.

     Disallow overmounting of such ephemeral entities.

Pull vfs file updates from Christian Brauner:
 "This is the work to cleanup and shrink struct file significantly.

  Right now, (focusing on x86) struct file is 232 bytes. After this
  series struct file will be 184 bytes aka 3 cacheline and a spare 8
  bytes for future extensions at the end of the struct.

  With struct file being as ubiquitous as it is this should make a
  difference for file heavy workloads and allow further optimizations in
  the future.

   - struct fown_struct was embedded into struct file letting it take up
     32 bytes in total when really it shouldn't even be embedded in
     struct file in the first place. Instead, actual users of struct
     fown_struct now allocate the struct on demand. This frees up 24
     bytes.

   - Move struct file_ra_state into the union containg the cleanup hooks
     and move f_iocb_flags out of the union. This closes a 4 byte hole
     we created earlier and brings struct file to 192 bytes. Which means
     struct file is 3 cachelines and we managed to shrink it by 40
     bytes.

   - Reorder struct file so that nothing crosses a cacheline.

     I suspect that in the future we will end up reordering some members
     to mitigate false sharing issues or just because someone does
     actually provide really good perf data.

   - Shrinking struct file to 192 bytes is only part of the work.

     Files use a slab that is SLAB_TYPESAFE_BY_RCU and when a kmem cache
     is created with SLAB_TYPESAFE_BY_RCU the free pointer must be
     located outside of the object because the cache doesn't know what
     part of the memory can safely be overwritten as it may be needed to
     prevent object recycling.

     That has the consequence that SLAB_TYPESAFE_BY_RCU may end up
     adding a new cacheline.

     So this also contains work to add a new kmem_cache_create_rcu()
     function that allows the caller to specify an offset where the
     freelist pointer is supposed to be placed. Thus avoiding the
     implicit addition of a fourth cacheline.

   - And finally this removes the f_version member in struct file.

     The f_version member isn't particularly well-defined. It is mainly
     used as a cookie to detect concurrent seeks when iterating
     directories. But it is also abused by some subsystems for
     completely unrelated things.

     It is mostly a directory and filesystem specific thing that doesn't
     really need to live in struct file and with its wonky semantics it
     really lacks a specific function.

     For pipes, f_version is (ab)used to defer poll notifications until
     a write has happened. And struct pipe_inode_info is used by
     multiple struct files in their ->private_data so there's no chance
     of pushing that down into file->private_data without introducing
     another pointer indirection.

     But pipes don't rely on f_pos_lock so this adds a union into struct
     file encompassing f_pos_lock and a pipe specific f_pipe member that
     pipes can use. This union of course can be extended to other file
     types and is similar to what we do in struct inode already"

Pull misc vfs updates from Christian Brauner:
 "This contains the usual pile of misc updates:

  Features:

   - Add F_CREATED_QUERY fcntl() that allows userspace to query whether
     a file was actually created. Often userspace wants to know whether
     an O_CREATE request did actually create a file without using
     O_EXCL. The current logic is that to first attempts to open the
     file without O_CREAT | O_EXCL and if ENOENT is returned userspace
     tries again with both flags. If that succeeds all is well. If it
     now reports EEXIST it retries.

     That works fairly well but some corner cases make this more
     involved. If this operates on a dangling symlink the first openat()
     without O_CREAT | O_EXCL will return ENOENT but the second openat()
     with O_CREAT | O_EXCL will fail with EEXIST.

     The reason is that openat() without O_CREAT | O_EXCL follows the
     symlink while O_CREAT | O_EXCL doesn't for security reasons. So
     it's not something we can really change unless we add an explicit
     opt-in via O_FOLLOW which seems really ugly.

     All available workarounds are really nasty (fanotify, bpf lsm etc)
     so add a simple fcntl().

   - Try an opportunistic lookup for O_CREAT. Today, when opening a file
     we'll typically do a fast lookup, but if O_CREAT is set, the kernel
     always takes the exclusive inode lock. This was likely done with
     the expectation that O_CREAT means that we always expect to do the
     create, but that's often not the case. Many programs set O_CREAT
     even in scenarios where the file already exists (see related
     F_CREATED_QUERY patch motivation above).

     The series contained in the pr rearranges the pathwalk-for-open
     code to also attempt a fast_lookup in certain O_CREAT cases. If a
     positive dentry is found, the inode_lock can be avoided altogether
     and it can stay in rcuwalk mode for the last step_into.

   - Expose the 64 bit mount id via name_to_handle_at()

     Now that we provide a unique 64-bit mount ID interface in statx(2),
     we can now provide a race-free way for name_to_handle_at(2) to
     provide a file handle and corresponding mount without needing to
     worry about racing with /proc/mountinfo parsing or having to open a
     file just to do statx(2).

     While this is not necessary if you are using AT_EMPTY_PATH and
     don't care about an extra statx(2) call, users that pass full paths
     into name_to_handle_at(2) need to know which mount the file handle
     comes from (to make sure they don't try to open_by_handle_at a file
     handle from a different filesystem) and switching to AT_EMPTY_PATH
     would require allocating a file for every name_to_handle_at(2) call

   - Add a per dentry expire timeout to autofs

     There are two fairly well known automounter map formats, the autofs
     format and the amd format (more or less System V and Berkley).

     Some time ago Linux autofs added an amd map format parser that
     implemented a fair amount of the amd functionality. This was done
     within the autofs infrastructure and some functionality wasn't
     implemented because it either didn't make sense or required extra
     kernel changes. The idea was to restrict changes to be within the
     existing autofs functionality as much as possible and leave changes
     with a wider scope to be considered later.

     One of these changes is implementing the amd options:
      1) "unmount", expire this mount according to a timeout (same as
         the current autofs default).
      2) "nounmount", don't expire this mount (same as setting the
         autofs timeout to 0 except only for this specific mount) .
      3) "utimeout=<seconds>", expire this mount using the specified
         timeout (again same as setting the autofs timeout but only for
         this mount)

     To implement these options per-dentry expire timeouts need to be
     implemented for autofs indirect mounts. This is because all map
     keys (mounts) for autofs indirect mounts use an expire timeout
     stored in the autofs mount super block info. structure and all
     indirect mounts use the same expire timeout.

  Fixes:

   - Fix missing fput for FSCONFIG_SET_FD in autofs

   - Use param->file for FSCONFIG_SET_FD in coda

   - Delete the 'fs/netfs' proc subtreee when netfs module exits

Pull thermal control updates from Rafael Wysocki:
 "These mostly continue to rework the thermal core and the thermal zone
  driver interface to make the code more straightforward and reduce
  bloat

  The most significant piece of this work is a change of the code
  related to binding cooling devices to thermal zones which, among other
  things, replaces two previously existing thermal zone operations with
  one allowing driver implementations to be much simpler

  There is also a new thermal core testing module allowing mock thermal
  zones to be created and controlled via debugfs in order to exercise
  the thermal core functionality. It is expected to be used for
  implementing thermal core self tests in the future

  Apart from the above, there are assorted thermal driver updates

  Specifics:

   - Update some thermal drivers to eliminate thermal_zone_get_trip()
     calls from them and get rid of that function (Rafael Wysocki)

   - Update the thermal sysfs code to store trip point attributes in
     trip descriptors and get to trip points via attribute pointers
     (Rafael Wysocki)

   - Move the computation of the low and high boundaries for
     thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
     Lezcano)

   - Introduce a debugfs-based facility for thermal core testing (Rafael
     Wysocki)

   - Replace the thermal zone .bind() and .unbind() callbacks for
     binding cooling devices to thermal zones with one .should_bind()
     callback used for deciding whether or not a given cooling devices
     should be bound to a given trip point in a given thermal zone
     (Rafael Wysocki)

   - Eliminate code that has no more users after the other changes, drop
     some redundant checks from the thermal core and clean it up (Rafael
     Wysocki)

   - Fix rounding of delay jiffies in the thermal core (Rafael Wysocki)

   - Refuse to accept trip point temperature or hysteresis that would
     lead to an invalid threshold value when setting them via sysfs
     (Rafael Wysocki)

   - Adjust states of all uninitialized instances in the .manage()
     callback of the Bang-bang thermal governor (Rafael Wysocki)

   - Drop a couple of redundant checks along with the code depending on
     them from the thermal core (Rafael Wysocki)

   - Rearrange the thermal core to avoid redundant checks and simplify
     control flow in a couple of code paths (Rafael Wysocki)

   - Add power domain DT bindings for new Amlogic SoCs (Georges Stark)

   - Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() in the ST

Pull networking updates from Jakub Kicinski:
 "The zero-copy changes are relatively significant, but regression risk
  should be contained. The feature needs to be used to cause trouble.

  Also it feels like we got an order of magnitude more semi-automated
  "refactoring" chaff than usual, I wonder if it's just us.

  Core & protocols:

   - Support Device Memory TCP, ability to zero-copy receive TCP
     payloads to a DMABUF region of memory while packet headers land
     separately in normal kernel buffers, and TCP processes then as
     usual.

   - The ability to read the PTP PHC (Physical Hardware Clock) alongside
     MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
     only CLOCK_REALTIME was supported.

   - Allow matching on all bits of IP DSCP for routing decisions.
     Previously we only supported on matching TOS bits in IPv4 which is
     a narrower interpretation of the same header field.

   - Increase the range of weights used for multi-path routing from
     8 bits to 16 bits.

   - Add support for IPv6 PIO p flag in the Prefix Information Option
     per draft-ietf-6man-pio-pflag.

   - IPv6 IOAM6 support for new tunsrc encap mode for better
     performance.

   - Detect destinations which blackhole MPTCP traffic and avoid
     initiating MPTCP connections to them for a certain period of time,
     1h by default.

   - Improve IPsec control path performance by removing the inexact
     policies list.

   - AF_VSOCK: add support for SIOCOUTQ ioctl.

   - Add enum for reasons TCP reset was sent for easier tracing.

   - Add SMC ringbufs usage statistics.

  Drivers:

   - Handle netconsole setup failures more gracefully, don't fail
     loading, retain the specified target as disabled.

   - Extend bonding's IPsec offload pass thru capabilities (ESN, stats).

  Filtering:

   - Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
     when long-lived sockets miss a chance to set additional callbacks
     if a sockops program was not attached early in their lifetime.

   - Support using BPF skb helpers in tracepoints.

   - Conntrack Netlink: support CTA_FILTER for flush.

   - Improve SCTP support in nfnetlink_queue.

   - Improve performance of large nftables flush transactions.

  Things we sprinkled into general kernel code:

   - selftests: support setting an "interpreter" for script files; make
     it easy to run as separate cases tests where one "interpreter" is
     fed various test descriptions (in our case packet sequences).

  Driver API:

   - Extend core and ethtool APIs to support many PHYs connected to a
     single interface (PHY topologies).

   - Extend cable diagnostics to specify whether Time Domain
     Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
     used.

   - Add library for implementing MAC-PHY Ethernet drivers for SPI
     devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
     Interface (TC6) standard.

   - Add helpers to the PHY framework, for PHYs following the Open
     Alliance standards:
       - 1000BaseT1 link settings
       - cable test and diagnostics

   - Support listing / dumping all allocated RSS contexts.

   - Add configuration for frequency Embedded SYNC in DPLL, which
     magically embeds sync pulses into Ethernet signaling.

There is a copy and paste bug so this code checks "sq->dep_wqe" where
"sq->wr_priv" was intended.  It could result in a NULL pointer
