 "The two large chunks is the header clean-up from Andy and the Qualcomm
  DT bindings clean-up from Krzysztof. Each which could give rise to
  conflicts, but I haven't seen any.

  The YAML conversions happening around the device tree is the biggest

  autovalidate these trees against strict schemas and it is paying off
  in lots of bugs found and ever prettier device trees. Sooner or later
  the transition will be complete, Krzysztof is fixing up all of the
  Qualcomm stuff, which is pretty voluminous.

d0f3ad23cf spi: Updates for v6.2 
A busy enough release, but not for the core which has only seen very
 small updates.  The biggest addition is the readdition of support for
 detailed configuration of the timings around chip selects.  That had
 been removed for lack of use but there's been applications found for it
 on Atmel systems.  Otherwise the updates are mostly feature additions
 and cleanups to existing drivers.
 
  - Provide a helper for getting device match data in a way that
    abstracts away which firmware interface is being used.
  - Re-add the spi_set_cs_timing() API for detailed configuration of the
    timing around chip select and support it on Atmel.
  - Support for MediaTek MT7986, Microchip PCI1xxxx, Nuvoton WPCM450 FIU
    and Socionext F_OSPI.
 
 There's a straightforward add/add conflict with the rpmsg tree in the
 xilinx firmware code (both trees got new users of the firmware added
 each needing new firmware<->kernel ioctls).
 
 There's a cross tree merge with I2C in order to use the new
 i2c_client_get_device_id() helper in some I2C attached SPI controllers
 as part of their conversion to I2C's probe_new() API.

c5589c436d regulator: Updates for v6.2 
Quite a quiet release for regulator, the diffstat is dominated by the
 I2C migration to probe_new() and the newly added MT6357 driver.  We've
 just one framework addition and the rest is all new device support,
 fixes and cleanups.

  - An API for requesting all regulators defined in DT.
  - Conversion of lots of drivers to the I2C probe_new() API.
  - Support for Mediatek MT6357, Qualcomm PM8550, PMR735a and
    Richtek RT6190.
 
 There's a cross tree merge with the I2C tree in order to use the new
 i2c_client_get_device_id() helper in the conversions to probe_new().

Pull regulator updates from Mark Brown:
 "Quite a quiet release for regulator, the diffstat is dominated by the
  I2C migration to probe_new() and the newly added MT6357 driver. We've
  just one framework addition and the rest is all new device support,
  fixes and cleanups.

b8cc9174ff regmap: Updates for v6.2 
A few new APIs here, support for the FSI bus (which is used in some
 PowerPC systems) plus a couple of new APIs, one allowing abstractions
 built on top of regmap to tell if the regmap can be used in an atomic
 context and one providing a callback for an in flight device which can't
 do interrupt masking very well.
 
 There's also a fix that I never got round to sending because it really
 should be fixed better but that's not happened yet and it does avoid the
 problem, the fix was in -next for a long time.

Pull drm updates from Dave Airlie:
 "The biggest highlight is that the accel subsystem framework is merged.
  Hopefully for 6.3 we will be able to line up a driver to use it.

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is
  also an ofdrm driver to take over offb on platforms it's used.

  Stuff outside my tree, the dma-buf patches hit a few places, the vc4
  firmware changes also do, and i915 has some interactions with MEI for
  discrete GPUs. I think all of those should have been acked/reviewed by
  relevant parties.

102f9d3d45 sound updates for 6.2-rc1 
This looks like a relatively calm development cycle; there have been
 only few changes in ALSA and ASoC core sides while we get lots of
 device-specific fixes and updates as usual.  Most of commits are about
 ASoC, including Intel SOF/AVS and many device tree updates.
 
 Below are some highlights:
 
 Core:
 - Improvement in memalloc helper for fallback allocations
 - More cleanups of ASoC DAPM code
 
 ASoC:
 - Factoring out of mapping hw_params onto SoundWire configuration
 - The ever ongoing overhauls of the Intel DSP code continue, including
   support for loading libraries and probes with IPC4 on SOF.
 - Support for more sample formats on JZ4740
 - Lots of device tree conversions and fixups
 - Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
   systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
   i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
   Rockchip RK3588
 
 ALSA:
 - Addition of PCM kselftest; still minimalistic but can be extended
   in future
 - Fixes for corner-case XRUNs with USB-audio implicit feedback mode
 - Usual device-specific quirk updates for USB- and HD-audio
 - FireWire DICE updates
 
 Also, this PR also contains a few cross-tree updates:
 - Some OMAP board file updates for removal of relevant OMAP platforms
 - A new I2C API update for I2C probe API adaption
 - A DRM update for the further hdmi-codec updates

8715c6d310 - Fix use-after-free races due to missing resource cleanup during DM 
target destruction in DM targets: thin-pool, cache, integrity and
   clone.
 
 - Fix ABBA deadlocks in DM thin-pool and cache targets due to their
   use of a bufio client (that has a shrinker whose locking can cause
   the incorrect locking order).
 
 - Fix DM cache target to set its needs_check flag after first aborting
   the metadata (whereby using reset persistent-data objects to update
   the superblock with, otherwise the superblock update could be
   dropped due to aborting metadata).  This was found with
   code-inspection when comparing with the equivalent in DM thinp
   code.
 
 - Fix DM thin-pool's presume to continue resuming the device even if
   the pool in is fail mode -- otherwise bios may never be failed up
   the IO stack (which will prevent resetting the thin-pool target via
   table reload)
 
 - Fix DM thin-pool's metadata to use proper btree root (from previous
   transaction) if metadata commit failed.

ata changes fro 6.2 include the ususal set of driver fixes and
 improvements as well as several patches improving libata core in
 preparation of the introduction of the support for the command duration
 limits feature. In more details:
 
   - Define the missing COMPLETED sense key in scsi header (from me).
 
   - Several patches to improve libata handling of the status of
     completed commands and the retry and sense data reported to the scsi
     layer for failed commands. In particular, this widen the support for
     NCQ autosense to all drives that support this feature instead of
     restricting this feature use to ZAC drives only (from Niklas).
 
   - Cleanup of the pata_mpc52xx and sata_dwc_460ex drivers to remove the
     use of the deprecated NO_IRQ macro (from Christophe).
 
   - Fix build dedependency on OF vs use of the of_match_ptr() macro to
     avoid build errors with the sata_gemini and pata_ftide010 drivers
     (from me).
 
   - Some libata cleanups using the new helper function
     ata_port_is_frozen() (from Niklas).
 
   - Improve internal command handling by not retrying commands that
     failed with a timeout (from Niklas).
 
   - Remove code for several unused libata helper functions (from

   - Remove the palmchip pata_bk3710 driver. A couple of other driver
     removal should come in through the arm tree pull request (from

 - Always ensure proper ordering in case of CQ ring overflow, which then
   means we can remove some work-arounds for that (Dylan)

 - Support completion batching for multishot, greatly increasing the
   efficiency for those (Dylan)

 - Flag epoll/eventfd wakeups done from io_uring, so that we can easily
   tell if we're recursing into io_uring again.

   Previously, this would have resulted in repeated multishot
   notifications if we had a dependency there. That could happen if an
   eventfd was registered as the ring eventfd, and we multishot polled
   for events on it. Or if an io_uring fd was added to epoll, and
   io_uring had a multishot request for the epoll fd.

Merge tag 'fs.xattr.simple.rework.rbtree.rwlock.v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping

Pull simple-xattr updates from Christian Brauner:
 "This ports the simple xattr infrastucture to rely on a simple rbtree
  protected by a read-write lock instead of a linked list protected by a
  spinlock.

  A while ago we received reports about scaling issues for filesystems
  using the simple xattr infrastructure that also support setting a
  larger number of xattrs. Specifically, cgroups and tmpfs.

  Both cgroupfs and tmpfs can be mounted by unprivileged users in
  unprivileged containers and root in an unprivileged container can set
  an unrestricted number of security.* xattrs and privileged users can
  also set unlimited trusted.* xattrs. A few more words on further that
  below. Other xattrs such as user.* are restricted for kernfs-based
  instances to a fairly limited number.

  As there are apparently users that have a fairly large number of
  xattrs we should scale a bit better. Using a simple linked list
  protected by a spinlock used for set, get, and list operations doesn't
  scale well if users use a lot of xattrs even if it's not a crazy
  number.

  Let's switch to a simple rbtree protected by a rwlock. It scales way
  better and gets rid of the perf issues some people reported. We
  originally had fancier solutions even using an rcu+seqlock protected
  rbtree but we had concerns about being to clever and also that
  deletion from an rbtree with rcu+seqlock isn't entirely safe.

  The rbtree plus rwlock is perfectly fine. By far the most common
  operation is getting an xattr. While setting an xattr is not and
  should be comparatively rare. And listxattr() often only happens when
  copying xattrs between files or together with the contents to a new
  file.

  Holding a lock across listxattr() is unproblematic because it doesn't
  list the values of xattrs. It can only be used to list the names of
  all xattrs set on a file. And the number of xattr names that can be
  listed with listxattr() is limited to XATTR_LIST_MAX aka 65536 bytes.
  If a larger buffer is passed then vfs_listxattr() caps it to
  XATTR_LIST_MAX and if more xattr names are found it will return
  -E2BIG. In short, the maximum amount of memory that can be retrieved
  via listxattr() is limited and thus listxattr() bounded.

  Of course, the API is broken as documented on xattr(7) already. While
  I have no idea how the xattr api ended up in this state we should
  probably try to come up with something here at some point. An iterator
  pattern similar to readdir() as an alternative to listxattr() or
  something else.

  Right now it is extremly strange that users can set millions of xattrs
  but then can't use listxattr() to know which xattrs are actually set.
  And it's really trivial to do:

	for i in {1..1000000}; do setfattr -n security.$i -v $i ./file1; done

  And around 5000 xattrs it's impossible to use listxattr() to figure
  out which xattrs are actually set. So I have suggested that we try to
  limit the number of xattrs for simple xattrs at least. But that's a
  future patch and I don't consider it very urgent.

  A bonus of this port to rbtree+rwlock is that we shrink the memory
  consumption for users of the simple xattr infrastructure.

  This also adds kernel documentation to all the functions"

Pull lsm updates from Paul Moore:

 - Improve the error handling in the device cgroup such that memory
   allocation failures when updating the access policy do not
   potentially alter the policy.

 - Some minor fixes to reiserfs to ensure that it properly releases
   LSM-related xattr values.

 - Update the security_socket_getpeersec_stream() LSM hook to take
   sockptr_t values.

   Previously the net/BPF folks updated the getsockopt code in the
   network stack to leverage the sockptr_t type to make it easier to
   pass both kernel and __user pointers, but unfortunately when they did
   so they didn't convert the LSM hook.

   While there was/is no immediate risk by not converting the LSM hook,
   it seems like this is a mistake waiting to happen so this patch
   proactively does the LSM hook conversion.

 - Convert vfs_getxattr_alloc() to return an int instead of a ssize_t
   and cleanup the callers. Internally the function was never going to
   return anything larger than an int and the callers were doing some
   very odd things casting the return value; this patch fixes all that
   and helps bring a bit of sanity to vfs_getxattr_alloc() and its
   callers.

 - More verbose, and helpful, LSM debug output when the system is booted
   with "lsm.debug" on the command line. There are examples in the
   commit description, but the quick summary is that this patch provides
   better information about which LSMs are enabled and the ordering in
   which they are processed.

 - General comment and kernel-doc fixes and cleanups.

Pull landlock updates from Mickaël Salaün:
 "This adds file truncation support to Landlock, contributed by Günther
  Noack. As described by Günther [1], the goal of these patches is to
  work towards a more complete coverage of file system operations that
  are restrictable with Landlock.

  The known set of currently unsupported file system operations in
  Landlock is described at [2]. Out of the operations listed there,
  truncate is the only one that modifies file contents, so these patches
  should make it possible to prevent the direct modification of file
  contents with Landlock.

  The new LANDLOCK_ACCESS_FS_TRUNCATE access right covers both the
  truncate(2) and ftruncate(2) families of syscalls, as well as open(2)
  with the O_TRUNC flag. This includes usages of creat() in the case
  where existing regular files are overwritten.

  Additionally, this introduces a new Landlock security blob associated
  with opened files, to track the available Landlock access rights at
  the time of opening the file. This is in line with Unix's general
  approach of checking the read and write permissions during open(), and
  associating this previously checked authorization with the opened
  file. An ongoing patch documents this use case [3].

  In order to treat truncate(2) and ftruncate(2) calls differently in an
  LSM hook, we split apart the existing security_path_truncate hook into
  security_path_truncate (for truncation by path) and
  security_file_truncate (for truncation of previously opened files)"

764822972d NFSD 6.2 Release Notes 
This release introduces support for the CB_RECALL_ANY operation.
 NFSD can send this operation to request that clients return any
 delegations they choose. The server uses this operation to handle
 low memory scenarios or indicate to a client when that client has
 reached the maximum number of delegations the server supports.
 
 The NFSv4.2 READ_PLUS operation has been simplified temporarily
 whilst support for sparse files in local filesystems and the VFS is
 improved.
 
 Two major data structure fixes appear in this release:
 
 * The nfs4_file hash table is replaced with a resizable hash table
   to reduce the latency of NFSv4 OPEN operations.
 
 * Reference counting in the NFSD filecache has been hardened against
   races.
 
 In furtherance of removing support for NFSv2 in a subsequent kernel
 release, a new Kconfig option enables server-side support for NFSv2
 to be left out of a kernel build.
 
 MAINTAINERS has been updated to indicate that changes to fs/exportfs
 should go through the NFSD tree.

Pull btrfs updates from David Sterba:
 "This round there are a lot of cleanups and moved code so the diffstat
  looks huge, otherwise there are some nice performance improvements and
  an update to raid56 reliability.

  User visible features:

   - raid56 reliability vs performance trade off:
      - fix destructive RMW for raid5 data (raid6 still needs work): do
        full checksum verification for all data during RMW cycle, this
        should prevent rewriting potentially corrupted data without
        notice
      - stripes are cached in memory which should reduce the performance
        impact but still can hurt some workloads
      - checksums are verified after repair again
      - this is the last option without introducing additional features
        (write intent bitmap, journal, another tree), the extra checksum
        read/verification was supposed to be avoided by the original
        implementation exactly for performance reasons but that caused
        all the reliability problems

   - discard=async by default for devices that support it

   - implement emergency flush reserve to avoid almost all unnecessary
     transaction aborts due to ENOSPC in cases where there are too many
     delayed refs or delayed allocation

   - skip block group synchronization if there's no change in used
     bytes, can reduce transaction commit count for some workloads

  Performance improvements:

   - fiemap and lseek:
      - overall speedup due to skipping unnecessary or duplicate
        searches (-40% run time)
      - cache some data structures and sharedness of extents (-30% run
        time)

   - send:
      - faster backref resolution when finding clones
      - cached leaf to root mapping for faster backref walking
      - improved clone/sharing detection
      - overall run time improvements (-70%)

  Core:

   - module initialization converted to a table of function pointers run
     in a sequence

   - preparation for fscrypt, extend passing file names across calls,
     dir item can store encryption status

   - raid56 updates:
      - more accurate error tracking of sectors within stripe
      - simplify recovery path and remove dedicated endio worker kthread
      - simplify scrub call paths
      - refactoring to support the extra data checksum verification
        during RMW cycle

   - tree block parentness checks consolidated and done at metadata read
     time

   - improved error handling

   - cleanups:
      - move a lot of code for better synchronization between kernel and
        user space sources, split big files
      - enum cleanups
      - GFP flag cleanups
      - header file cleanups, prototypes, dependencies
      - redundant parameter cleanups
      - inline extent handling simplifications
      - inode parameter conversion
      - data structure cleanups, reductions, renames, merges"

97971df811 dlm for 6.2 
These patches include the usual cleanups and minor fixes, the removal of
 code that is no longer needed due to recent improvements, and
 improvements to processing large volumes of messages during heavy
 locking activity.
 
 - Misc code cleanup.
 
 - Fix a couple socket handling bugs: a double release on an error path
   and a data-ready race in an accept loop.
 
 - Remove code for resending dir-remove messages. This code is no longer
   needed since the midcomms layer now ensures the messages are resent if
   needed.
 
 - Add tracepoints for dlm messages.
 
 - Improve callback queueing by replacing the fixed array with a list.
 
 - Simplify the handling of a remove message followed by a lookup
   message by sending both without releasing a spinlock in between.
 
 - Improve the concurrency of sending and receiving messages by holding
   locks for a shorter time, and changing how workqueues are used.
 
 - Remove old code for shutting down sockets, which is no longer needed
   with the reliable connection handling that was recently added.

Pull xattr audit fix from Seth Forshee:
 "This is a single patch to remove auditing of the capability check in
  simple_xattr_list().

  This check is done to check whether trusted xattrs should be included
  by listxattr(2). SELinux will normally log a denial when capable() is
  called and the task's SELinux context doesn't have the corresponding
  capability permission allowed, which can end up spamming the log.

  Since a failed check here cannot be used to infer malicious intent,
  auditing is of no real value, and it makes sense to stop auditing the
  capability check"

ad0d9da164 fsverity updates for 6.2 
The main change this cycle is to stop using the PG_error flag to track
 verity failures, and instead just track failures at the bio level.  This
 follows a similar fscrypt change that went into 6.1, and it is a step
 towards freeing up PG_error for other uses.
 
 There's also one other small cleanup.

This release adds SM4 encryption support, contributed by Tianjia Zhang.
 SM4 is a Chinese block cipher that is an alternative to AES.
 
 I recommend against using SM4, but (according to Tianjia) some people
 are being required to use it.  Since SM4 has been turning up in many
 other places (crypto API, wireless, TLS, OpenSSL, ARMv8 CPUs, etc.), it
 hasn't been very controversial, and some people have to use it, I don't
 think it would be fair for me to reject this optional feature.

Pull idmapping updates from Christian Brauner:
 "Last cycle we've already made the interaction with idmapped mounts
  more robust and type safe by introducing the vfs{g,u}id_t type. This
  cycle we concluded the conversion and removed the legacy helpers.

  Currently we still pass around the plain namespace that was attached
  to a mount. This is in general pretty convenient but it makes it easy
  to conflate namespaces that are relevant on the filesystem - with
  namespaces that are relevent on the mount level. Especially for
  filesystem developers without detailed knowledge in this area this can
  be a potential source for bugs.

  Instead of passing the plain namespace we introduce a dedicated type
  struct mnt_idmap and replace the pointer with a pointer to a struct
  mnt_idmap. There are no semantic or size changes for the mount struct
  caused by this.

  We then start converting all places aware of idmapped mounts to rely
  on struct mnt_idmap. Once the conversion is done all helpers down to
  the really low-level make_vfs{g,u}id() and from_vfs{g,u}id() will take
  a struct mnt_idmap argument instead of two namespace arguments. This
  way it becomes impossible to conflate the two removing and thus
  eliminating the possibility of any bugs. Fwiw, I fixed some issues in
  that area a while ago in ntfs3 and ksmbd in the past. Afterwards only
  low-level code can ultimately use the associated namespace for any
  permission checks. Even most of the vfs can be completely obivious
  about this ultimately and filesystems will never interact with it in
  any form in the future.

  A struct mnt_idmap currently encompasses a simple refcount and pointer
  to the relevant namespace the mount is idmapped to. If a mount isn't
  idmapped then it will point to a static nop_mnt_idmap and if it
  doesn't that it is idmapped. As usual there are no allocations or
  anything happening for non-idmapped mounts. Everthing is carefully
  written to be a nop for non-idmapped mounts as has always been the
  case.

  If an idmapped mount is created a struct mnt_idmap is allocated and a
  reference taken on the relevant namespace. Each mount that gets
  idmapped or inherits the idmap simply bumps the reference count on
  struct mnt_idmap. Just a reminder that we only allow a mount to change
  it's idmapping a single time and only if it hasn't already been
  attached to the filesystems and has no active writers.

  The actual changes are fairly straightforward but this will have huge
  benefits for maintenance and security in the long run even if it
  causes some churn.

  Note that this also makes it possible to extend struct mount_idmap in
  the future. For example, it would be possible to place the namespace
  pointer in an anonymous union together with an idmapping struct. This
  would allow us to expose an api to userspace that would let it specify
  idmappings directly instead of having to go through the detour of
  setting up namespaces at all"

Pull setgid inheritance updates from Christian Brauner:
 "This contains the work to make setgid inheritance consistent between
  modifying a file and when changing ownership or mode as this has been
  a repeated source of very subtle bugs. The gist is that we perform the
  same permission checks in the write path as we do in the ownership and
  mode changing paths after this series where we're currently doing
  different things.

  We've already made setgid inheritance a lot more consistent and
  reliable in the last releases by moving setgid stripping from the
  individual filesystems up into the vfs. This aims to make the logic
  even more consistent and easier to understand and also to fix
  long-standing overlayfs setgid inheritance bugs. Miklos was nice
  enough to just let me carry the trivial overlayfs patches from Amir
  too.

  Below is a more detailed explanation how the current difference in
  setgid handling lead to very subtle bugs exemplified via overlayfs
  which is a victim of the current rules. I hope this explains why I
  think taking the regression risk here is worth it.

  A long while ago I found a few setgid inheritance bugs in overlayfs in
  the write path in certain conditions. Amir recently picked this back
  up in [1] and I jumped on board to fix this more generally.

  On the surface all that overlayfs would need to fix setgid inheritance
  would be to call file_remove_privs() or file_modified() but actually
  that isn't enough because the setgid inheritance api is wildly
  inconsistent in that area.

  Before this pr setgid stripping in file_remove_privs()'s old
  should_remove_suid() helper was inconsistent with other parts of the
  vfs. Specifically, it only raises ATTR_KILL_SGID if the inode is
  S_ISGID and S_IXGRP but not if the inode isn't in the caller's groups
  and the caller isn't privileged over the inode although we require
  this already in setattr_prepare() and setattr_copy() and so all
  filesystem implement this requirement implicitly because they have to
  use setattr_{prepare,copy}() anyway.

  But the inconsistency shows up in setgid stripping bugs for overlayfs
  in xfstests (e.g., generic/673, generic/683, generic/685, generic/686,
  generic/687). For example, we test whether suid and setgid stripping
  works correctly when performing various write-like operations as an
  unprivileged user (fallocate, reflink, write, etc.):

      echo "Test 1 - qa_user, non-exec file $verb"
      setup_testfile
      chmod a+rws $junk_file
      commit_and_check "$qa_user" "$verb" 64k 64k

  The test basically creates a file with 6666 permissions. While the
  file has the S_ISUID and S_ISGID bits set it does not have the S_IXGRP
  set.

  On a regular filesystem like xfs what will happen is:

      sys_fallocate()
      -> vfs_fallocate()
         -> xfs_file_fallocate()
            -> file_modified()
               -> __file_remove_privs()
                  -> dentry_needs_remove_privs()
                     -> should_remove_suid()
                  -> __remove_privs()
                     newattrs.ia_valid = ATTR_FORCE | kill;
                     -> notify_change()
                        -> setattr_copy()

  In should_remove_suid() we can see that ATTR_KILL_SUID is raised
  unconditionally because the file in the test has S_ISUID set.

  But we also see that ATTR_KILL_SGID won't be set because while the
  file is S_ISGID it is not S_IXGRP (see above) which is a condition for
  ATTR_KILL_SGID being raised.

  So by the time we call notify_change() we have attr->ia_valid set to
  ATTR_KILL_SUID | ATTR_FORCE.

  Now notify_change() sees that ATTR_KILL_SUID is set and does:

      ia_valid      = attr->ia_valid |= ATTR_MODE
      attr->ia_mode = (inode->i_mode & ~S_ISUID);

  which means that when we call setattr_copy() later we will definitely
  update inode->i_mode. Note that attr->ia_mode still contains S_ISGID.

  Now we call into the filesystem's ->setattr() inode operation which
  will end up calling setattr_copy(). Since ATTR_MODE is set we will
  hit:

      if (ia_valid & ATTR_MODE) {
              umode_t mode = attr->ia_mode;
              vfsgid_t vfsgid = i_gid_into_vfsgid(mnt_userns, inode);
              if (!vfsgid_in_group_p(vfsgid) &&
                  !capable_wrt_inode_uidgid(mnt_userns, inode, CAP_FSETID))
                      mode &= ~S_ISGID;
              inode->i_mode = mode;
      }

  and since the caller in the test is neither capable nor in the group
  of the inode the S_ISGID bit is stripped.

  But assume the file isn't suid then ATTR_KILL_SUID won't be raised
  which has the consequence that neither the setgid nor the suid bits
  are stripped even though it should be stripped because the inode isn't
  in the caller's groups and the caller isn't privileged over the inode.

  If overlayfs is in the mix things become a bit more complicated and
  the bug shows up more clearly.

  When e.g., ovl_setattr() is hit from ovl_fallocate()'s call to
  file_remove_privs() then ATTR_KILL_SUID and ATTR_KILL_SGID might be
  raised but because the check in notify_change() is questioning the
  ATTR_KILL_SGID flag again by requiring S_IXGRP for it to be stripped
  the S_ISGID bit isn't removed even though it should be stripped:

      sys_fallocate()
      -> vfs_fallocate()
         -> ovl_fallocate()
            -> file_remove_privs()
               -> dentry_needs_remove_privs()
                  -> should_remove_suid()
               -> __remove_privs()
                  newattrs.ia_valid = ATTR_FORCE | kill;
                  -> notify_change()
                     -> ovl_setattr()
                        /* TAKE ON MOUNTER'S CREDS */
                        -> ovl_do_notify_change()
                           -> notify_change()
                        /* GIVE UP MOUNTER'S CREDS */
           /* TAKE ON MOUNTER'S CREDS */
           -> vfs_fallocate()
              -> xfs_file_fallocate()
                 -> file_modified()
                    -> __file_remove_privs()
                       -> dentry_needs_remove_privs()
                          -> should_remove_suid()
                       -> __remove_privs()
                          newattrs.ia_valid = attr_force | kill;
                          -> notify_change()

  The fix for all of this is to make file_remove_privs()'s
  should_remove_suid() helper perform the same checks as we already
  require in setattr_prepare() and setattr_copy() and have
  notify_change() not pointlessly requiring S_IXGRP again. It doesn't
  make any sense in the first place because the caller must calculate
  the flags via should_remove_suid() anyway which would raise
  ATTR_KILL_SGID

  Note that some xfstests will now fail as these patches will cause the
  setgid bit to be lost in certain conditions for unprivileged users
  modifying a setgid file when they would've been kept otherwise. I
  think this risk is worth taking and I explained and mentioned this
  multiple times on the list [2].

  Enforcing the rules consistently across write operations and
  chmod/chown will lead to losing the setgid bit in cases were it
  might've been retained before.

  While I've mentioned this a few times but it's worth repeating just to
  make sure that this is understood. For the sake of maintainability,
  consistency, and security this is a risk worth taking.

  If we really see regressions for workloads the fix is to have special
  setgid handling in the write path again with different semantics from
  chmod/chown and possibly additional duct tape for overlayfs. I'll
  update the relevant xfstests with if you should decide to merge this
  second setgid cleanup.

  Before that people should be aware that there might be failures for
  fstests where unprivileged users modify a setgid file"

Pull VFS acl updates from Christian Brauner:
 "This contains the work that builds a dedicated vfs posix acl api.

  The origins of this work trace back to v5.19 but it took quite a while
  to understand the various filesystem specific implementations in
  sufficient detail and also come up with an acceptable solution.

  As we discussed and seen multiple times the current state of how posix
  acls are handled isn't nice and comes with a lot of problems: The
  current way of handling posix acls via the generic xattr api is error
  prone, hard to maintain, and type unsafe for the vfs until we call
  into the filesystem's dedicated get and set inode operations.

  It is already the case that posix acls are special-cased to death all
  the way through the vfs. There are an uncounted number of hacks that
  operate on the uapi posix acl struct instead of the dedicated vfs
  struct posix_acl. And the vfs must be involved in order to interpret
  and fixup posix acls before storing them to the backing store, caching
  them, reporting them to userspace, or for permission checking.

  Currently a range of hacks and duct tape exist to make this work. As
  with most things this is really no ones fault it's just something that
  happened over time. But the code is hard to understand and difficult
  to maintain and one is constantly at risk of introducing bugs and
  regressions when having to touch it.

  Instead of continuing to hack posix acls through the xattr handlers
  this series builds a dedicated posix acl api solely around the get and
  set inode operations.

  Going forward, the vfs_get_acl(), vfs_remove_acl(), and vfs_set_acl()
  helpers must be used in order to interact with posix acls. They
  operate directly on the vfs internal struct posix_acl instead of
  abusing the uapi posix acl struct as we currently do. In the end this
  removes all of the hackiness, makes the codepaths easier to maintain,
  and gets us type safety.

  This series passes the LTP and xfstests suites without any
  regressions. For xfstests the following combinations were tested:
   - xfs
   - ext4
   - btrfs
   - overlayfs
   - overlayfs on top of idmapped mounts
   - orangefs
   - (limited) cifs

  There's more simplifications for posix acls that we can make in the
  future if the basic api has made it.

  A few implementation details:

   - The series makes sure to retain exactly the same security and
     integrity module permission checks. Especially for the integrity
     modules this api is a win because right now they convert the uapi
     posix acl struct passed to them via a void pointer into the vfs
     struct posix_acl format to perform permission checking on the mode.

     There's a new dedicated security hook for setting posix acls which
     passes the vfs struct posix_acl not a void pointer. Basing checking
     on the posix acl stored in the uapi format is really unreliable.
     The vfs currently hacks around directly in the uapi struct storing
     values that frankly the security and integrity modules can't
     correctly interpret as evidenced by bugs we reported and fixed in
     this area. It's not necessarily even their fault it's just that the
     format we provide to them is sub optimal.

   - Some filesystems like 9p and cifs need access to the dentry in
     order to get and set posix acls which is why they either only
     partially or not even at all implement get and set inode
     operations. For example, cifs allows setxattr() and getxattr()
     operations but doesn't allow permission checking based on posix
     acls because it can't implement a get acl inode operation.

     Thus, this patch series updates the set acl inode operation to take
     a dentry instead of an inode argument. However, for the get acl
     inode operation we can't do this as the old get acl method is
     called in e.g., generic_permission() and inode_permission(). These
     helpers in turn are called in various filesystem's permission inode
     operation. So passing a dentry argument to the old get acl inode
     operation would amount to passing a dentry to the permission inode
     operation which we shouldn't and probably can't do.

     So instead of extending the existing inode operation Christoph
     suggested to add a new one. He also requested to ensure that the
     get and set acl inode operation taking a dentry are consistently
     named. So for this version the old get acl operation is renamed to
     ->get_inode_acl() and a new ->get_acl() inode operation taking a
     dentry is added. With this we can give both 9p and cifs get and set
     acl inode operations and in turn remove their complex custom posix
     xattr handlers.

     In the future I hope to get rid of the inode method duplication but
     it isn't like we have never had this situation. Readdir is just one
     example. And frankly, the overall gain in type safety and the more
     pleasant api wise are simply too big of a benefit to not accept
     this duplication for a while.

   - We've done a full audit of every codepaths using variant of the
     current generic xattr api to get and set posix acls and
     surprisingly it isn't that many places. There's of course always a
     chance that we might have missed some and if so I'm sure we'll find
     them soon enough.

     The crucial codepaths to be converted are obviously stacking
     filesystems such as ecryptfs and overlayfs.

     For a list of all callers currently using generic xattr api helpers
     see [2] including comments whether they support posix acls or not.

   - The old vfs generic posix acl infrastructure doesn't obey the
     create and replace semantics promised on the setxattr(2) manpage.
     This patch series doesn't address this. It really is something we
     should revisit later though.

  The patches are roughly organized as follows:

   (1) Change existing set acl inode operation to take a dentry
       argument (Intended to be a non-functional change)

   (2) Rename existing get acl method (Intended to be a non-functional
       change)

   (3) Implement get and set acl inode operations for filesystems that
       couldn't implement one before because of the missing dentry.
       That's mostly 9p and cifs (Intended to be a non-functional
       change)

   (4) Build posix acl api, i.e., add vfs_get_acl(), vfs_remove_acl(),
       and vfs_set_acl() including security and integrity hooks
       (Intended to be a non-functional change)

   (5) Implement get and set acl inode operations for stacking
       filesystems (Intended to be a non-functional change)

   (6) Switch posix acl handling in stacking filesystems to new posix
       acl api now that all filesystems it can stack upon support it.

   (7) Switch vfs to new posix acl api (semantical change)

   (8) Remove all now unused helpers

   (9) Additional regression fixes reported after we merged this into
       linux-next

  Thanks to Seth for a lot of good discussion around this and
  encouragement and input from Christoph"
