       - 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         layout changes that originally made that bug manifest were probably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.

         clarifications of comments.

      linux/types.h: reinstate "__bitwise__" macro for user space use · caa28984
      Linus Torvalds authored
      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.

      Linus Torvalds authored
      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"

         - repair super block num_devices automatically if it does not match
           the number of device items
      
         - defrag can convert inline extents to regular extents, up to now
           inline files were skipped but the setting of mount option
           max_inline could affect the decision logic
      
         - zoned:
            - minimal accepted zone size is explicitly set to 4MiB
            - make zone reclaim less aggressive and don't reclaim if there are
              enough free zones
            - add per-profile sysfs tunable of the reclaim threshold
      
         - allow automatic block group reclaim for non-zoned filesystems, with

      Merge tag 'erofs-for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs · 65965d95
      Linus Torvalds authored
      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"

      Pull fs idmapping updates from Christian Brauner:
       "This contains two minor updates:
      
         - An update to the idmapping documentation by Rodrigo making it
           easier to understand that we first introduce several use-cases that
           fail without idmapped mounts simply to explain how they can be
           handled with idmapped mounts.
      
         - When changing a mount's idmapping we now hold writers to make it
           more robust.
      
           This is similar to turning a mount ro with the difference that in
           contrast to turning a mount ro changing the idmapping can only ever
           be done once while a mount can transition between ro and rw as much
           as it wants.
      
           The vfs layer itself takes care to retrieve the idmapping of a
           mount once ensuring that the idmapping used for vfs permission
           checking is identical to the idmapping passed down to the
           filesystem. All filesystems with FS_ALLOW_IDMAP raised take the
           same precautions as the vfs in code-paths that are outside of
           direct control of the vfs such as ioctl()s.
      
           However, holding writers makes this more robust and predictable for
           both the kernel and userspace.
      
           This is a minor user-visible change. But it is extremely unlikely
           to matter. The caller must've created a detached mount via
           OPEN_TREE_CLONE and then handed that O_PATH fd to another process
           or thread which then must've gotten a writable fd for that mount
           and started creating files in there while the caller is still
           changing mount properties. While not impossible it will be an
           extremely rare corner-case and should in general be considered a
           bug in the application. Consider making a mount MOUNT_ATTR_NOEXEC
           or MOUNT_ATTR_NODEV while allowing someone else to perform lookups
           or exec'ing in parallel by handing them a copy of the
           OPEN_TREE_CLONE fd or another fd beneath that mount.
      
           I've pinged all major users of idmapped mounts pointing out this
           change and none of them have active writers on a mount while still
           changing mount properties. It would've been strange if they did.
      
        The rest and majority of the work will be coming through the overlayfs
        tree this cycle. In addition to overlayfs this cycle should also see
        support for idmapped mounts on erofs as I've acked a patch to this
        effect a little while ago"

        numbers for different entities may be in different scales, add support
        for some new hardware, fix bugs and clean up code in multiple places.
      
        Specifics:
      
         - Update the Energy Model support code to allow the Energy Model to
           be artificial, which means that the power values may not be on a
           uniform scale with other devices providing power information, and
           update the cpufreq_cooling and devfreq_cooling thermal drivers to

           chemical scd30 driver (Jonathan Cameron).
      
         - Add namespace variants of EXPORT[_GPL]_SIMPLE_DEV_PM_OPS and
           PM-runtime counterparts (Jonathan Cameron).
      
         - Move symbol exports in the IIO chemical scd30 driver into the

           Cohen).
      
         - Fix some kernel-doc comments in hibernation code (Yang Li, Haowen
           Bai).
      
         - Preserve ACPI-table override during hibernation (Amadeusz
           Sławiński).

           governor to be used (Ulf Hansson).
      
         - Fix cpufreq governor clean up code to avoid using kfree() directly
           to free kobject-based items (Kevin Hao).
      
         - Prepare cpufreq for powerpc's asm/prom.h cleanup (Christophe

         - Make intel_pstate notify frequency invariance code when no_turbo is

         - Add Sapphire Rapids OOB mode support to intel_pstate (Srinivas
           Pandruvada).
      
         - Make cpufreq avoid unnecessary frequency updates due to mismatch
           between hardware and the frequency table (Viresh Kumar).
      
         - Make remove_cpu_dev_symlink() clear the real_cpus mask to simplify

           calling convention for some driver callbacks consistent (Rafael
           Wysocki).
      
         - Avoid accessing half-initialized cpufreq policies from the show()
           and store() sysfs functions (Schspa Shi).

       "We've got twelve patches queued for v5.19, with most being fairly

         - The checkreqprot and runtime disable knobs have been deprecated for
           some time with no active users that we can find. In an effort to
           move things along we are adding a pause when the knobs are used to
           help make the deprecation more noticeable in case anyone is still
           using these hacks in the shadows.
      
         - We've added the anonymous inode class name to the AVC audit records
           when anonymous inodes are involved. This should make writing policy
           easier when anonymous inodes are involved.
      
         - More constification work. This is fairly straightforward and the
           source of most of the diffstat.

      ext4: only allow test_dummy_encryption when supported · 5f41fdae
      Eric Biggers authored
      Make the test_dummy_encryption mount option require that the encrypt
      feature flag be already enabled on the filesystem, rather than
      automatically enabling it.  Practically, this means that "-O encrypt"
      will need to be included in MKFS_OPTIONS when running xfstests with the
      test_dummy_encryption mount option.  (ext4/053 also needs an update.)
      
      Moreover, as long as the preconditions for test_dummy_encryption are
      being tightened anyway, take the opportunity to start rejecting it when
      !CONFIG_FS_ENCRYPTION rather than ignoring it.
      
      The motivation for requiring the encrypt feature flag is that:
      
      - Having the filesystem auto-enable feature flags is problematic, as it
        bypasses the usual sanity checks.  The specific issue which came up
        recently is that in kernel versions where ext4 supports casefold but
        not encrypt+casefold (v5.1 through v5.10), the kernel will happily add
        the encrypt flag to a filesystem that has the casefold flag, making it
        unmountable -- but only for subsequent mounts, not the initial one.
        This confused the casefold support detection in xfstests, causing
        generic/556 to fail rather than be skipped.
      
      - The xfstests-bld test runners (kvm-xfstests et al.) already use the
        required mkfs flag, so they will not be affected by this change.  Only
        users of test_dummy_encryption alone will be affected.  But, this
        option has always been for testing only, so it should be fine to
        require that the few users of this option update their test scripts.
      
      - f2fs already requires it (for its equivalent feature flag).

      The error ext4 extents is as follows:
      0af3 0300 0400 0000 00000000    extent_header
      00000000 0100 0000 12000000     extent1

      02000000 0400 0000 14000000     extent3
      
      In the ext4_valid_extent_entries function,
      if prev is 0, no error is returned even if lblock<=prev.
      This was intended to skip the check on the first extent, but
      in the error image above, prev=0+1-1=0 when checking the second extent,
      so even though lblock<=prev, the function does not return an error.
      As a result, bug_ON occurs in __es_tree_search and the system panics.
      
      To solve this problem, we only need to check that:
      1. The lblock of the first extent is not less than 0.
      2. The lblock of the next extent  is not less than
         the next block of the previous extent.
      The same applies to extent_idx.

      ext4: avoid cycles in directory h-tree · 3ba733f8
      Jan Kara authored
      A maliciously corrupted filesystem can contain cycles in the h-tree
      stored inside a directory. That can easily lead to the kernel corrupting
      tree nodes that were already verified under its hands while doing a node
      split and consequently accessing unallocated memory. Fix the problem by
      verifying traversed block numbers are unique.

      Before splitting a directory block verify its directory entries are sane
      so that the splitting code does not access memory it should not.

      ext4: filter out EXT4_FC_REPLAY from on-disk superblock field s_state · c878bea3
      Theodore Ts'o authored
      The EXT4_FC_REPLAY bit in sbi->s_mount_state is used to indicate that
      we are in the middle of replay the fast commit journal.  This was
      actually a mistake, since the sbi->s_mount_info is initialized from
      es->s_state.  Arguably s_mount_state is misleadingly named, but the
      name is historical --- s_mount_state and s_state dates back to ext2.
      
      What should have been used is the ext4_{set,clear,test}_mount_flag()
      inline functions, which sets EXT4_MF_* bits in sbi->s_mount_flags.
      
      The problem with using EXT4_FC_REPLAY is that a maliciously corrupted
      superblock could result in EXT4_FC_REPLAY getting set in
      s_mount_state.  This bypasses some sanity checks, and this can trigger
      a BUG() in ext4_es_cache_extent().  As a easy-to-backport-fix, filter
      out the EXT4_FC_REPLAY bit for now.  We should eventually transition
      away from EXT4_FC_REPLAY to something like EXT4_MF_REPLAY.

      Before this patch, function bh_get used block_map to figure out the
      block it needed to read in from the quota_change file. This patch
      changes it to use iomap directly to make it more efficient.

      gfs2: use i_lock spin_lock for inode qadata · 5fcff61e
      Bob Peterson authored
      Before this patch, functions gfs2_qa_get and _put used the i_rw_mutex to
      prevent simultaneous access to its i_qadata. But i_rw_mutex is now used
      for many other things, including iomap_begin and end, which causes a
      conflict according to lockdep. We cannot just remove the lock since
      simultaneous opens (gfs2_open -> gfs2_open_common -> gfs2_qa_get) can
      then stomp on each others values for i_qadata.
      
      This patch solves the conflict by using the i_lock spin_lock in the inode
      to prevent simultaneous access.
