In qdisc_run_begin(), smp_mb__before_atomic() used before test_bit()
does not provide any ordering guarantee as test_bit() is not an atomic
operation. This, added to the fact that the spin_trylock() call at
the beginning of qdisc_run_begin() does not guarantee acquire
semantics if it does not grab the lock, makes it possible for the
following statement :

if (test_bit(__QDISC_STATE_MISSED, &qdisc->state))

to be executed before an enqueue operation called before
qdisc_run_begin().

As a result the following race can happen :

           CPU 1                             CPU 2

      qdisc_run_begin()               qdisc_run_begin() /* true */
        set(MISSED)                            .
      /* returns false */                      .
          .                            /* sees MISSED = 1 */
          .                            /* so qdisc not empty */
          .                            __qdisc_run()
          .                                    .

|         .                                smp_mb __after_atomic();
|         .                                    .
|         .                                /* recheck the queue */

|     smp_mb__before_atomic() /* not enough */
|         .
 ---- if (test_bit(MISSED))
        return false;   /* exit */

In the above scenario, CPU 1 and CPU 2 both try to grab the
qdisc->seqlock at the same time. Only CPU 2 succeeds and enters the
bypass code path, where it emits its skb then calls __qdisc_run().

CPU1 fails, sets MISSED and goes down the traditionnal enqueue() +
dequeue() code path. But when executing qdisc_run_begin() for the
second time, after enqueuing its skbuff, it sees the MISSED bit still
set (by itself) and consequently chooses to exit early without setting
it again nor trying to grab the spinlock again.

Meanwhile CPU2 has seen MISSED = 1, cleared it, checked the queue
and found it empty, so it returned.

At the end of the sequence, we end up with skb1 enqueued in the
backlog, both CPUs out of __dev_xmit_skb(), the MISSED bit not set,
and no __netif_schedule() called made. skb1 will now linger in the
qdisc until somebody later performs a full __qdisc_run(). Associated
to the bypass capacity of the qdisc, and the ability of the TCP layer
to avoid resending packets which it knows are still in the qdisc, this
can lead to serious traffic "holes" in a TCP connection.

We fix this by replacing the smp_mb__before_atomic() / test_bit() /
set_bit() / smp_mb__after_atomic() sequence inside qdisc_run_begin()
by a single test_and_set_bit() call, which is more concise and
enforces the needed memory barriers.

At the moment, if devm_of_phy_get() returns an error the serdes
simply isn't set. While it is bad to ignore an error in general, there
is a particular bug that network isn't working if the serdes driver is
compiled as a module. In that case, devm_of_phy_get() returns
-EDEFER_PROBE and the error is silently ignored.

The serdes is optional, it is not there if the port is using RGMII, in
which case devm_of_phy_get() returns -ENODEV. Rearrange the error
handling so that -ENODEV will be handled but other error codes will
abort the probing.

Since 3e135cd4 ("netfilter: nft_dynset: dynamic stateful expression
instantiation"), it is possible to attach stateful expressions to set
elements.

cd5125d8 ("netfilter: nf_tables: split set destruction in deactivate
and destroy phase") introduces conditional destruction on the object to
accomodate transaction semantics.

nft_expr_init() calls expr->ops->init() first, then check for
NFT_STATEFUL_EXPR, this stills allows to initialize a non-stateful
lookup expressions which points to a set, which might lead to UAF since
the set is not properly detached from the set->binding for this case.
Anyway, this combination is non-sense from nf_tables perspective.

This patch fixes this problem by checking for NFT_STATEFUL_EXPR before
expr->ops->init() is called.

The psock_snd test sends and receives packets over loopback, and
the test results depend on parameter settings:
Set rp_filter=0,
or set rp_filter=1 and accept_local=1
so that the test will pass. Otherwise, this test will fail with
Resource temporarily unavailable:
sudo ./psock_snd.sh
dgram
tx: 128
rx: 142
./psock_snd: recv: Resource temporarily unavailable

For most distro kernel releases(like Ubuntu or Centos), the parameter
rp_filter is enabled by default, so it's necessary to enable the
parameter lo.accept_local in psock_snd test. And this test runs
inside a netns, changing a sysctl is fine.

     dynamically sized ringbuf reservations without extra memory copies.

  Protocols
  ---------

   - Retire port only listening_hash table, add a second bind table
     hashed by port and address. Avoid linear list walk when binding to
     very popular ports (e.g. 443).

   - Add bridge FDB bulk flush filtering support allowing user space to
     remove all FDB entries matching a condition.

   - Introduce accept_unsolicited_na sysctl for IPv6 to implement
     router-side changes for RFC9131.

   - Support for MPTCP path manager in user space.

   - Add MPTCP support for fallback to regular TCP for connections that
     have never connected additional subflows or transmitted
     out-of-sequence data (partial support for RFC8684 fallback).

   - Avoid races in MPTCP-level window tracking, stabilize and improve
     throughput.

   - Support lockless operation of GRE tunnels with seq numbers enabled.

   - WiFi support for host based BSS color collision detection.

   - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

   - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).

   - Add support for listing line cards in switches (devlink).

   - Add helpers for reporting page pool statistics with ethtool -S.

   - Add support for reading clock cycles when using PTP virtual clocks,
     instead of having the driver convert to time before reporting. This
     makes it possible to report time from different vclocks.

   - Support configuring low-latency Tx descriptor push via ethtool.

   - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

Pull printk updates from Petr Mladek:

 - Offload writing printk() messages on consoles to per-console
   kthreads.

   It prevents soft-lockups when an extensive amount of messages is
   printed. It was observed, for example, during boot of large systems
   with a lot of peripherals like disks or network interfaces.

   It prevents live-lockups that were observed, for example, when
   messages about allocation failures were reported and a CPU handled
   consoles instead of reclaiming the memory. It was hard to solve even
   with rate limiting because it would need to take into account the
   amount of messages and the speed of all consoles.

   It is a must to have for real time. Otherwise, any printk() might
   break latency guarantees.

   The per-console kthreads allow to handle each console on its own
   speed. Slow consoles do not longer slow down faster ones. And
   printk() does not longer unpredictably slows down various code paths.

   There are situations when the kthreads are either not available or
   not reliable, for example, early boot, suspend, or panic. In these
   situations, printk() uses the legacy mode and tries to handle
   consoles immediately.

 - Add documentation for the printk index.

Pull slab updates from Vlastimil Babka:

 - Conversion of slub_debug stack traces to stackdepot, allowing more
   useful debugfs-based inspection for e.g. memory leak debugging.
   Allocation and free debugfs info now includes full traces and is
   sorted by the unique trace frequency.

   The stackdepot conversion was already attempted last year but
   reverted by ae14c63a. The memory overhead (while not actually
   enabled on boot) has been meanwhile solved by making the large
   stackdepot allocation dynamic. The xfstest issues haven't been
   reproduced on current kernel locally nor in -next, so the slab cache
   layout changes that originally made that bug manifest were probably
   not the root cause.

Commit c724c866 ("linux/types.h: remove unnecessary __bitwise__")
was right that there are no users of __bitwise__ in the kernel, but it
turns out there are user space users of it that do expect it.

It is, after all, in the uapi directory, so user space usage is to be
expected.

Instead of reverting the commit completely, let's just clarify the
situation so that it doesn't happen again, and have some in-code
explanations for why that "__bitwise__" still exists.

Pull iomap updates from Darrick Wong:
 "There's a couple of corrections sent in by Andreas for some accounting
  errors.

  The biggest change this time around is that writeback errors longer
  clear pageuptodate nor does XFS invalidate the page cache anymore.
  This brings XFS (and gfs2/zonefs) behavior in line with every other
  Linux filesystem driver, and fixes some UAF bugs that only cropped up
  after willy turned on multipage folios for XFS in 5.18-rc1.

  Regrettably, it took all the way to the end of the 5.18 cycle to find
  the source of these bugs and reach a consensus that XFS' writeback
  failure behavior from 20 years ago is no longer necessary.

  Summary:

   - Fix a couple of accounting errors in the buffered io code.

   - Discontinue the practice of marking folios !uptodate and
     invalidating them when writeback fails.

     This fixes some UAF bugs when multipage folios are enabled, and
     brings the behavior of XFS/gfs/zonefs into alignment with the
     behavior of all the other Linux filesystems"

Pull erofs (and fscache) updates from Gao Xiang:
 "After working on it on the mailing list for more than half a year, we
  finally form 'erofs over fscache' feature into shape. Hopefully it
  could bring more possibility to the communities.

  The story mainly started from a new project what we called "RAFS v6" [1]
  for Nydus image service almost a year ago, which enhances EROFS to be
  a new form of one bootstrap (which includes metadata representing the
  whole fs tree) + several data-deduplicated content addressable blobs
  (actually treated as multiple devices). Each blob can represent one
  container image layer but not quite exactly since all new data can be
  fully existed in the previous blobs so no need to introduce another
  new blob.

  It is actually not a new idea (at least on my side it's much like a
  simpilied casync [2] for now) and has many benefits over per-file
  blobs or some other exist ways since typically each RAFS v6 image only
  has dozens of device blobs instead of thousands of per-file blobs.
  It's easy to be signed with user keys as a golden image, transfered
  untouchedly with minimal overhead over the network, kept in some type
  of storage conveniently, and run with (optional) runtime verification
  but without involving too many irrelevant features crossing the system
  beyond EROFS itself. At least it's our final goal and we're keeping
  working on it. There was also a good summary of this approach from the
  casync author [3].

  Regardless further optimizations, this work is almost done in the
  previous Linux release cycles. In this round, we'd like to introduce
  on-demand load for EROFS with the fscache/cachefiles infrastructure,
  considering the following advantages:

   - Introduce new file-based backend to EROFS. Although each image only
     contains dozens of blobs but in densely-deployed runC host for
     example, there could still be massive blobs on a machine, which is
     messy if each blob is treated as a device. In contrast, fscache and
     cachefiles are really great interfaces for us to make them work.

   - Introduce on-demand load to fscache and EROFS. Previously, fscache
     is mainly used to caching network-likewise filesystems, now it can
     support on-demand downloading for local fses too with the exact
     localfs on-disk format. It has many advantages which we're been
     described in the latest patchset cover letter [4]. In addition to
     that, most importantly, the cached data is still stored in the
     original local fs on-disk format so that it's still the one signed
     with private keys but only could be partially available. Users can
     fully trust it during running. Later, users can also back up
     cachefiles easily to another machine.

   - More reliable on-demand approach in principle. After data is all
     available locally, user daemon can be no longer online in some use
     cases, which helps daemon crash recovery (filesystems can still in
     service) and hot-upgrade (user daemon can be upgraded more
     frequently due to new features or protocols introduced.)

   - Other format can also be converted to EROFS filesystem format over
     the internet on the fly with the new on-demand load feature and
     mounted. That is entirely possible with on-demand load feature as
     long as such archive format metadata can be fetched in advance like
     stargz.

  In addition, although currently our target user is Nydus image service [5],
  but laterly, it can be used for other use cases like on-demand system
  booting, etc. As for the fscache on-demand load feature itself,
  strictly it can be used for other local fses too. Laterly we could
  promote most code to the iomap infrastructure and also enhance it in
  the read-write way if other local fses are interested.

  Thanks David Howells for taking so much time and patience on this
  these months, many thanks with great respect here again! Thanks Jeffle
  for working on this feature and Xin Yin from Bytedance for
  asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and
  Yan Song for testing, much appeciated. We're also exploring more
  possibly over fscache cache management over FSDAX for secure
  containers and working on more improvements and useful features for
  fscache, cachefiles, and on-demand load.

  In addition to "erofs over fscache", NFS export and idmapped mount are
  also completed in this cycle for container use cases as well.

  Summary:

   - Add erofs on-demand load support over fscache

   - Support NFS export for erofs

   - Support idmapped mounts for erofs

   - Don't prompt for risk any more when using big pcluster

   - Fix buffer copy overflow of ztailpacking feature

   - Several minor cleanups"
