Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
warning that was added in 6.2.
- Some reworking of the Documentation/process front page to, hopefully,
make it more useful.
- Various kernel-doc tweaks to, for example, make it deal properly with
__counted_by annotations.
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained
effort by Randy, Vegard, and myself has addressed almost all of those,
bringing the documentation back into sync with the code. The fixes are
going through the appropriate maintainer trees.
- Various improvements to the HTML rendered docs, including automatic links
to Git revisions and a nice new pulldown to make translations easy to
access.
- Speaking of translations, more of those for Spanish and Chinese.
...plus the usual stream of documentation updates and typo fixes.

New code for 6.8:
* New features/functionality
* Online repair
* Reserve disk space for online repairs.
* Fix misinteraction between the AIL and btree bulkloader because of
which the bulk load fails to queue a buffer for writeback if it
happens to be on the AIL list.
* Prevent transaction reservation overflows when reaping blocks during
online repair.
* Whenever possible, bulkloader now copies multiple records into a
block.
* Support repairing of
1. Per-AG free space, inode and refcount btrees.
2. Ondisk inodes.
3. File data and attribute fork mappings.
* Verify the contents of
1. Inode and data fork of realtime bitmap file.
2. Quota files.
* Introduce MF_MEM_PRE_REMOVE. This will be used to notify tasks about
a pmem device being removed.
* Bug fixes
* Fix memory leak of recovered attri intent items.
* Fix UAF during log intent recovery.
* Fix realtime geometry integer overflows.
* Prevent scrub from live locking in xchk_iget.
* Prevent fs shutdown when removing files during low free disk space.
* Prevent transaction reservation overflow when extending an RT device.
* Prevent incorrect warning from being printed when extending a
filesystem.
* Fix an off-by-one error in xreap_agextent_binval.
* Serialize access to perag radix tree during deletion operation.
* Fix perag memory leak during growfs.
* Allow allocation of minlen realtime extent when the maximum sized
realtime free extent is minlen in size.
* Cleanups
* Remove duplicate boilerplate code spread across functionality associated
with different log items.
* Cleanup resblks interfaces.
* Pass defer ops pointer to defer helpers instead of an enum.
* Initialize di_crc in xfs_log_dinode to prevent KMSAN warnings.
* Use static_assert() instead of BUILD_BUG_ON_MSG() to validate size of
structures and structure member offsets. This is done in order to be
able to share the code with userspace.
* Move XFS documentation under a new directory specific to XFS.
* Do not invoke deferred ops' ->create_done callback if the deferred
operation does not have an intent item associated with it.
* Remove duplicate inclusion of header files from scrub/health.c.
* Refactor Realtime code.
* Cleanup attr code.

Quite a lot of kexec work this time around. Many singleton patches in
many places. The notable patch series are:
- nilfs2 folio conversion from Matthew Wilcox in "nilfs2: Folio
conversions for file paths".
- Additional nilfs2 folio conversion from Ryusuke Konishi in "nilfs2:
Folio conversions for directory paths".
- IA64 remnant removal in Heiko Carstens's "Remove unused code after
IA-64 removal".
- Arnd Bergmann has enabled the -Wmissing-prototypes warning everywhere
in "Treewide: enable -Wmissing-prototypes". This had some followup
fixes:
- Nathan Chancellor has cleaned up the hexagon build in the series
"hexagon: Fix up instances of -Wmissing-prototypes".
- Nathan also addressed some s390 warnings in "s390: A couple of
fixes for -Wmissing-prototypes".
- Arnd Bergmann addresses the same warnings for MIPS in his series
"mips: address -Wmissing-prototypes warnings".
- Baoquan He has made kexec_file operate in a top-down-fitting manner
similar to kexec_load in the series "kexec_file: Load kernel at top of
system RAM if required"
- Baoquan He has also added the self-explanatory "kexec_file: print out
debugging message if required".
- Some checkstack maintenance work from Tiezhu Yang in the series
"Modify some code about checkstack".
- Douglas Anderson has disentangled the watchdog code's logging when
multiple reports are occurring simultaneously. The series is "watchdog:
Better handling of concurrent lockups".

Many singleton patches against the MM code. The patch series which
are included in this merge do the following:
- Peng Zhang has done some mapletree maintainance work in the
series
"maple_tree: add mt_free_one() and mt_attr() helpers"
"Some cleanups of maple tree"
- In the series "mm: use memmap_on_memory semantics for dax/kmem"
Vishal Verma has altered the interworking between memory-hotplug
and dax/kmem so that newly added 'device memory' can more easily
have its memmap placed within that newly added memory.
- Matthew Wilcox continues folio-related work (including a few
fixes) in the patch series
"Add folio_zero_tail() and folio_fill_tail()"
"Make folio_start_writeback return void"
"Fix fault handler's handling of poisoned tail pages"
"Convert aops->error_remove_page to ->error_remove_folio"
"Finish two folio conversions"
"More swap folio conversions"
- Kefeng Wang has also contributed folio-related work in the series
"mm: cleanup and use more folio in page fault"
- Jim Cromie has improved the kmemleak reporting output in the
series "tweak kmemleak report format".
- In the series "stackdepot: allow evicting stack traces" Andrey
Konovalov to permits clients (in this case KASAN) to cause
eviction of no longer needed stack traces.
- Charan Teja Kalla has fixed some accounting issues in the page
allocator's atomic reserve calculations in the series "mm:
page_alloc: fixes for high atomic reserve caluculations".
- Dmitry Rokosov has added to the samples/ dorectory some sample
code for a userspace memcg event listener application. See the
series "samples: introduce cgroup events listeners".
- Some mapletree maintanance work from Liam Howlett in the series
"maple_tree: iterator state changes".
- Nhat Pham has improved zswap's approach to writeback in the
series "workload-specific and memory pressure-driven zswap
writeback".
- DAMON/DAMOS feature and maintenance work from SeongJae Park in
the series
"mm/damon: let users feed and tame/auto-tune DAMOS"
"selftests/damon: add Python-written DAMON functionality tests"
"mm/damon: misc updates for 6.8"
- Yosry Ahmed has improved memcg's stats flushing in the series
"mm: memcg: subtree stats flushing and thresholds".
- In the series "Multi-size THP for anonymous memory" Ryan Roberts
has added a runtime opt-in feature to transparent hugepages which
improves performance by allocating larger chunks of memory during
anonymous page faults.
- Matthew Wilcox has also contributed some cleanup and maintenance
work against eh buffer_head code int he series "More buffer_head
cleanups".
- Suren Baghdasaryan has done work on Andrea Arcangeli's series
"userfaultfd move option". UFFDIO_MOVE permits userspace heap
compaction algorithms to move userspace's pages around rather than
UFFDIO_COPY'a alloc/copy/free.
- Stefan Roesch has developed a "KSM Advisor", in the series
"mm/ksm: Add ksm advisor". This is a governor which tunes KSM's
scanning aggressiveness in response to userspace's current needs.
- Chengming Zhou has optimized zswap's temporary working memory
use in the series "mm/zswap: dstmem reuse optimizations and
cleanups".
- Matthew Wilcox has performed some maintenance work on the
writeback code, both code and within filesystems. The series is
"Clean up the writeback paths".
- Andrey Konovalov has optimized KASAN's handling of alloc and
free stack traces for secondary-level allocators, in the series
"kasan: save mempool stack traces".
- Andrey also performed some KASAN maintenance work in the series
"kasan: assorted clean-ups".
- David Hildenbrand has gone to town on the rmap code. Cleanups,
more pte batching, folio conversions and more. See the series
"mm/rmap: interface overhaul".
- Kinsey Ho has contributed some maintenance work on the MGLRU
code in the series "mm/mglru: Kconfig cleanup".

Merge tag 'vfs-6.8.super' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs super updates from Christian Brauner:
"This contains the super work for this cycle including the long-awaited
series by Jan to make it possible to prevent writing to mounted block
devices:
- Writing to mounted devices is dangerous and can lead to filesystem
corruption as well as crashes. Furthermore syzbot comes with more
and more involved examples how to corrupt block device under a
mounted filesystem leading to kernel crashes and reports we can do
nothing about. Add tracking of writers to each block device and a
kernel cmdline argument which controls whether other writeable
opens to block devices open with BLK_OPEN_RESTRICT_WRITES flag are
allowed.
Note that this effectively only prevents modification of the
particular block device's page cache by other writers. The actual
device content can still be modified by other means - e.g. by
issuing direct scsi commands, by doing writes through devices lower
in the storage stack (e.g. in case loop devices, DM, or MD are
involved) etc. But blocking direct modifications of the block
device page cache is enough to give filesystems a chance to perform
data validation when loading data from the underlying storage and
thus prevent kernel crashes.
Syzbot can use this cmdline argument option to avoid uninteresting
crashes. Also users whose userspace setup does not need writing to
mounted block devices can set this option for hardening. We expect
that this will be interesting to quite a few workloads.
Btrfs is currently opted out of this because they still haven't
merged patches we require for this to work from three kernel
releases ago.
- Reimplement block device freezing and thawing as holder operations
on the block device.
This allows us to extend block device freezing to all devices
associated with a superblock and not just the main device. It also
allows us to remove get_active_super() and thus another function
that scans the global list of superblocks.
Freezing via additional block devices only works if the filesystem
chooses to use @fs_holder_ops for these additional devices as well.
That currently only includes ext4 and xfs.
Earlier releases switched get_tree_bdev() and mount_bdev() to use
@fs_holder_ops. The remaining nilfs2 open-coded version of
mount_bdev() has been converted to rely on @fs_holder_ops as well.
So block device freezing for the main block device will continue to
work as before.
There should be no regressions in functionality. The only special
case is btrfs where block device freezing for the main block device
never worked because sb->s_bdev isn't set. Block device freezing
for btrfs can be fixed once they can switch to @fs_holder_ops but
that can happen whenever they're ready"

mm: thp: introduce multi-size THP sysfs interface
In preparation for adding support for anonymous multi-size THP, introduce new sysfs structure that will be used to control the new behaviours. A new directory is added under transparent_hugepage for each supported THP size, and contains an `enabled` file, which can be set to "inherit" (to inherit the global setting), "always", "madvise" or "never". For now, the kernel still only supports PMD-sized anonymous THP, so only 1 directory is populated. The first half of the change converts transhuge_vma_suitable() and hugepage_vma_check() so that they take a bitfield of orders for which the user wants to determine support, and the functions filter out all the orders that can't be supported, given the current sysfs configuration and the VMA dimensions. The resulting functions are renamed to thp_vma_suitable_orders() and thp_vma_allowable_orders() respectively. Convenience functions that take a single, unencoded order and return a boolean are also defined as thp_vma_suitable_order() and thp_vma_allowable_order(). The second half of the change implements the new sysfs interface. It has been done so that each supported THP size has a `struct thpsize`, which describes the relevant metadata and is itself a kobject. This is pretty minimal for now, but should make it easy to add new per-thpsize files to the interface if needed in future (e.g. per-size defrag). Rather than keep the `enabled` state directly in the struct thpsize, I've elected to directly encode it into huge_anon_orders_[always|madvise|inherit] bitfields since this reduces the amount of work required in thp_vma_allowable_orders() which is called for every page fault. See Documentation/admin-guide/mm/transhuge.rst, as modified by this commit, for details of how the new sysfs interface works.

docs: filesystems: document the squashfs specific mount options
When SQUASHFS_CHOICE_DECOMP_BY_MOUNT is set, the "threads" mount option can be used to specify the decompression mode: single-threaded, multi-threaded, percpu or the number of threads used for decompression. When SQUASHFS_CHOICE_DECOMP_BY_MOUNT is not set, SQUASHFS_DECOMP_MULTI and SQUASHFS_MOUNT_DECOMP_THREADS are both set, the "threads" option can also be used to specify the number of threads used for decompression. This mount option is only mentioned in fs/squashfs/Kconfig, which makes it difficult to find. Another mount option available is "errors", which can be configured to panic the kernel when squashfs errors are encountered. Add both these options to the squashfs documentation, making them more noticeable.

ovl: add support for appending lowerdirs one by one
Add new mount options lowerdir+ and datadir+ that can be used to add layers to lower layers stack one by one. Unlike the legacy lowerdir mount option, special characters (i.e. colons and cammas) are not unescaped with these new mount options. The new mount options can be repeated to compose a large stack of lower layers, but they may not be mixed with the lagacy lowerdir mount option, because for displaying lower layers in mountinfo, we do not want to mix escaped with unescaped lower layers path syntax. Similar to data-only layer rules with the lowerdir mount option, the datadir+ option must follow at least one lowerdir+ option and the lowerdir+ option must not follow the datadir+ option. If the legacy lowerdir mount option follows lowerdir+ and datadir+ mount options, it overrides them. Sepcifically, calling: fsconfig(FSCONFIG_SET_STRING, "lowerdir", "", 0); can be used to reset previously setup lower layers.

NFSD 6.7 Release Notes
This release completes the SunRPC thread scheduler work that was begun in v6.6. The scheduler can now find an svc thread to wake in constant time and without a list walk. Thanks again to Neil Brown for this overhaul. Lorenzo Bianconi contributed infrastructure for a netlink-based NFSD control plane. The long-term plan is to provide the same functionality as found in /proc/fs/nfsd, plus some interesting additions, and then migrate the NFSD user space utilities to netlink. A long series to overhaul NFSD's NFSv4 operation encoding was applied in this release. The goals are to bring this family of encoding functions in line with the matching NFSv4 decoding functions and with the NFSv2 and NFSv3 XDR functions, preparing the way for better memory safety and maintainability. A further improvement to NFSD's write delegation support was contributed by Dai Ngo. This adds a CB_GETATTR callback, enabling the server to retrieve cached size and mtime data from clients holding write delegations. If the server can retrieve this information, it does not have to recall the delegation in some cases. The usual panoply of bug fixes and minor improvements round out this release. As always I am grateful to all contributors, reviewers, and testers. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmU5IuoACgkQM2qzM29m f5eVsg//bVp8S93ci/oDlKfzOwH2fO5e5rna91wrDpJxkd51h6KTx55dSRG5sjAZ EywIVOann6xCtsixAPyff5Cweg2dWvzQRsy1ZnvWQ1qZBzD5KAJY5LPkeSFUCKBo Zani/qTOYbxzgFMjZx+yDSXDPKG68WYZBQK59SI7mURu4SYdk8aRyNY8mjHfr0Vh Aqrcny4oVtXV4sL5P5G/2FUW7WKT3olA3jSYlRRNMhbs2qpEemRCCrspOEMMad+b t1+ZCg+U27PMranvOJnof4RU7peZbaxDWA0gyiUbivVXVtZn9uOs0ffhktkvechL ePc33dqdp2ITdKIPA6JlaRv5WflKXQw0YYM9Kv5mcR4A2el7owL4f/pMlPhtbYwJ IOJv15KdKVN979G2e6WMYiKK+iHfaUUguhMEXnfnGoAajHOZNQiUEo3iFQAD7LDc DvMF8d9QqYmB9IW8FOYaRRfZGJOQHf3TL79Nd08z/bn5swvlvfj77leux9Sb+0/m Luk2Xvz2AJVSXE31wzabaGHkizN+BtH+e4MMbXUHBPW5jE9v7XOnEUFr4UdZyr9P Gl87A7NcrzNjJWT5TrnzM4sOslNsx46Aeg+VuNt2fSRn2dm6iBu2B8s0N4imx6dV PX1y9VSLq5WRhjrFZ1qeiZdsuTaQtrEiNDoRIQR6nCJPAV80iFk= =B4wJ -----END PGP SIGNATURE----- Merge tag 'nfsd-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "This release completes the SunRPC thread scheduler work that was begun in v6.6.

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Rename and export helpers that get write access to a mount. They
are used in overlayfs to get write access to the upper mount.
- Print the pretty name of the root device on boot failure. This
helps in scenarios where we would usually only print
"unknown-block(1,2)".
- Add an internal SB_I_NOUMASK flag. This is another part in the
endless POSIX ACL saga in a way.
When POSIX ACLs are enabled via SB_POSIXACL the vfs cannot strip
the umask because if the relevant inode has POSIX ACLs set it might
take the umask from there. But if the inode doesn't have any POSIX
ACLs set then we apply the umask in the filesytem itself. So we end
up with:
(1) no SB_POSIXACL -> strip umask in vfs
(2) SB_POSIXACL -> strip umask in filesystem
The umask semantics associated with SB_POSIXACL allowed filesystems
that don't even support POSIX ACLs at all to raise SB_POSIXACL
purely to avoid umask stripping. That specifically means NFS v4 and
Overlayfs. NFS v4 does it because it delegates this to the server
and Overlayfs because it needs to delegate umask stripping to the
upper filesystem, i.e., the filesystem used as the writable layer.
This went so far that SB_POSIXACL is raised eve on kernels that
don't even have POSIX ACL support at all.
Stop this blatant abuse and add SB_I_NOUMASK which is an internal
superblock flag that filesystems can raise to opt out of umask
handling. That should really only be the two mentioned above. It's
not that we want any filesystems to do this. Ideally we have all
umask handling always in the vfs.
- Make overlayfs use SB_I_NOUMASK too.
- Now that we have SB_I_NOUMASK, stop checking for SB_POSIXACL in
IS_POSIXACL() if the kernel doesn't have support for it. This is a
very old patch but it's only possible to do this now with the wider
cleanup that was done.
- Follow-up work on fake path handling from last cycle. Citing mostly
from Amir:
When overlayfs was first merged, overlayfs files of regular files
and directories, the ones that are installed in file table, had a
"fake" path, namely, f_path is the overlayfs path and f_inode is
the "real" inode on the underlying filesystem.
In v6.5, we took another small step by introducing of the
backing_file container and the file_real_path() helper. This change
allowed vfs and filesystem code to get the "real" path of an
overlayfs backing file. With this change, we were able to make
fsnotify work correctly and report events on the "real" filesystem
objects that were accessed via overlayfs.
This method works fine, but it still leaves the vfs vulnerable to
new code that is not aware of files with fake path. A recent
example is commit

exportfs: make ->encode_fh() a mandatory method for NFS export
Rename the default helper for encoding FILEID_INO32_GEN* file handles to generic_encode_ino32_fh() and convert the filesystems that used the default implementation to use the generic helper explicitly. After this change, exportfs_encode_inode_fh() no longer has a default implementation to encode FILEID_INO32_GEN* file handles. This is a step towards allowing filesystems to encode non-decodeable file handles for fanotify without having to implement any export_operations.

file: convert to SLAB_TYPESAFE_BY_RCU
In recent discussions around some performance improvements in the file handling area we discussed switching the file cache to rely on SLAB_TYPESAFE_BY_RCU which allows us to get rid of call_rcu() based freeing for files completely. This is a pretty sensitive change overall but it might actually be worth doing. The main downside is the subtlety. The other one is that we should really wait for Jann's patch to land that enables KASAN to handle SLAB_TYPESAFE_BY_RCU UAFs. Currently it doesn't but a patch for this exists. With SLAB_TYPESAFE_BY_RCU objects may be freed and reused multiple times which requires a few changes. So it isn't sufficient anymore to just acquire a reference to the file in question under rcu using atomic_long_inc_not_zero() since the file might have already been recycled and someone else might have bumped the reference. In other words, callers might see reference count bumps from newer users. For this reason it is necessary to verify that the pointer is the same before and after the reference count increment. This pattern can be seen in get_file_rcu() and __files_get_rcu(). In addition, it isn't possible to access or check fields in struct file without first aqcuiring a reference on it. Not doing that was always very dodgy and it was only usable for non-pointer data in struct file. With SLAB_TYPESAFE_BY_RCU it is necessary that callers first acquire a reference under rcu or they must hold the files_lock of the fdtable. Failing to do either one of this is a bug. Thanks to Jann for pointing out that we need to ensure memory ordering between reallocations and pointer check by ensuring that all subsequent loads have a dependency on the second load in get_file_rcu() and providing a fixup that was folded into this patch.

fscrypt: track master key presence separately from secret
Master keys can be in one of three states: present, incompletely removed, and absent (as per FSCRYPT_KEY_STATUS_* used in the UAPI). Currently, the way that "present" is distinguished from "incompletely removed" internally is by whether ->mk_secret exists or not. With extent-based encryption, it will be necessary to allow per-extent keys to be derived while the master key is incompletely removed, so that I/O on open files will reliably continue working after removal of the key has been initiated. (We could allow I/O to sometimes fail in that case, but that seems problematic for reasons such as writes getting silently thrown away and diverging from the existing fscrypt semantics.) Therefore, when the filesystem is using extent-based encryption, ->mk_secret can't be wiped when the key becomes incompletely removed. As a prerequisite for doing that, this patch makes the "present" state be tracked using a new field, ->mk_present. No behavior is changed yet. The basic idea here is borrowed from Josef Bacik's patch "fscrypt: use a flag to indicate that the master key is being evicted" (https://lore.kernel.org/r/e86c16dddc049ff065f877d793ad773e4c6bfad9.1696970227.git.josef@toxicpanda.com). I reimplemented it using a "present" bool instead of an "evicted" flag, fixed a couple bugs, and tried to update everything to be consistent. Note: I considered adding a ->mk_status field instead, holding one of FSCRYPT_KEY_STATUS_*. At first that seemed nice, but it ended up being more complex (despite simplifying FS_IOC_GET_ENCRYPTION_KEY_STATUS), since it would have introduced redundancy and had weird locking rules.

fscrypt: support crypto data unit size less than filesystem block size
Until now, fscrypt has always used the filesystem block size as the granularity of file contents encryption. Two scenarios have come up where a sub-block granularity of contents encryption would be useful: 1. Inline crypto hardware that only supports a crypto data unit size that is less than the filesystem block size. 2. Support for direct I/O at a granularity less than the filesystem block size, for example at the block device's logical block size in order to match the traditional direct I/O alignment requirement. (1) first came up with older eMMC inline crypto hardware that only supports a crypto data unit size of 512 bytes. That specific case ultimately went away because all systems with that hardware continued using out of tree code and never actually upgraded to the upstream inline crypto framework. But, now it's coming back in a new way: some current UFS controllers only support a data unit size of 4096 bytes, and there is a proposal to increase the filesystem block size to 16K. (2) was discussed as a "nice to have" feature, though not essential, when support for direct I/O on encrypted files was being upstreamed. Still, the fact that this feature has come up several times does suggest it would be wise to have available. Therefore, this patch implements it by using one of the reserved bytes in fscrypt_policy_v2 to allow users to select a sub-block data unit size. Supported data unit sizes are powers of 2 between 512 and the filesystem block size, inclusively. Support is implemented for both the FS-layer and inline crypto cases. This patch focuses on the basic support for sub-block data units. Some things are out of scope for this patch but may be addressed later: - Supporting sub-block data units in combination with FSCRYPT_POLICY_FLAG_IV_INO_LBLK_64, in most cases. Unfortunately this combination usually causes data unit indices to exceed 32 bits, and thus fscrypt_supported_policy() correctly disallows it. The users who potentially need this combination are using f2fs. To support it, f2fs would need to provide an option to slightly reduce its max file size. - Supporting sub-block data units in combination with FSCRYPT_POLICY_FLAG_IV_INO_LBLK_32. This has the same problem described above, but also it will need special code to make DUN wraparound still happen on a FS block boundary. - Supporting use case (2) mentioned above. The encrypted direct I/O code will need to stop requiring and assuming FS block alignment. This won't be hard, but it belongs in a separate patch. - Supporting this feature on filesystems other than ext4 and f2fs. (Filesystems declare support for it via their fscrypt_operations.) On UBIFS, sub-block data units don't make sense because UBIFS encrypts variable-length blocks as a result of compression. CephFS could support it, but a bit more work would be needed to make the fscrypt_*_block_inplace functions play nicely with sub-block data units. I don't think there's a use case for this on CephFS anyway. Link: https://lore.kernel.org/r/20230925055451.59499-6-ebiggers@kernel.org Signed-off-by: Eric Biggers <ebiggers@google.com> |

porting: document superblock as block device holder
We've changed the holder of the block device which has consequences. Document this clearly and in detail so filesystem and vfs developers have a proper digital paper trail. Signed-off-by: Christian Brauner <brauner@kernel.org> |

Mixed with some fixes and cleanups, this brings in reasonably complete
fscrypt support to CephFS! The list of things which don't work with encryption should be fairly short, mostly around the edges: fallocate (not supported well in CephFS to begin with), copy_file_range (requires re-encryption), non-default striping patterns. This was a multi-year effort principally by Jeff Layton with assistance from Xiubo Li, Luís Henriques and others, including several dependant changes in the MDS, netfs helper library and fscrypt framework itself. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEydHwtzie9C7TfviiSn/eOAIR84sFAmT4pl4THGlkcnlvbW92 QGdtYWlsLmNvbQAKCRBKf944AhHzi5kzB/4sMgzZyUa3T1vA/G2pPvEkyy1qDxsW y+o4dDMWA9twcrBVpNuGd54wbXpmO/LAekHEdorjayH+f0zf10MsnP1ePz9WB3NG jr7RRujb+Gpd2OFYJXGSEbd3faTg8M2kpGCCrVe7SFNoyu8z9NwFItwWMog5aBjX ODGQrq+kA4ARA6xIqwzF5gP0zr+baT9rWhQdm7Xo9itWdosnbyDLJx1dpEfLuqBX te3SmifDzedn3Gw73hdNo/+ybw0kHARoK+RmXCTsoDDQw+JsoO9KxZF5Q8QcDELq 2woPNp0Hl+Dm4MkzGnPxv56Qj8ZDViS59syXC0CfGRmu4nzF1Rw+0qn5 =/WlE -----END PGP SIGNATURE----- Merge tag 'ceph-for-6.6-rc1' of https://github.com/ceph/ceph-client Pull ceph updates from Ilya Dryomov: "Mixed with some fixes and cleanups, this brings in reasonably complete fscrypt support to CephFS!

gfs2 fixes
- Fix a glock state (non-)transition bug when a dlm request times out and is canceled, and we have locking requests that can now be granted immediately. - Various fixes and cleanups in how the logd and quotad daemons are woken up and terminated. - Fix several bugs in the quota data reference counting and shrinking. Free quota data objects synchronously in put_super() instead of letting call_rcu() run wild. - Make sure not to deallocate quota data during a withdraw; rather, defer quota data deallocation to put_super(). Withdraws can happen in contexts in which callers on the stack are holding quota data references. - Many minor quota fixes and cleanups by Bob. - Update the the mailing list address for gfs2 and dlm. (It's the same list for both and we are moving it to gfs2@lists.linux.dev.) - Various other minor cleanups. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEEJZs3krPW0xkhLMTc1b+f6wMTZToFAmT3T7UUHGFncnVlbmJh QHJlZGhhdC5jb20ACgkQ1b+f6wMTZTqxhw/+IWp+4cY4htNkTRG7xkheTeQ+5whG NU40mp7Hj+WY5GoHqsk676q1pBkVAq5mNN1kt9S/oC6lLHrdu1HLpdIkgFow2nAC nDqlEqx9/Da9Q4H/+K442usO90S4o1MmOXOE9xcGcvJLqK4FLDOVDXbUWa43OXrK 4HxgjgGSNPF4itD+U0o/V4f19jQ+4cNwmo6hGLyhsYillaUHiIXJezQlH7XycByM qGJqlG6odJ56wE38NG8Bt9Lj+91PsLLqO1TJxSYyzpf0h9QGQ2ySvu6/esTXwxWO XRuT4db7yjyAUhJoJMw+YU77xWQTz0/jriIDS7VqzvR1ns3GPaWdtb31TdUTBG4H IvBA8ep3oxHtcYFoPzCLBXgOIDej6KjAgS3RSv51yLeaZRHFUBc21fTSXbcDTIUs gkusZlRNQ9ANdBCVyf8hZxbE54HnaBJ8dKMZtynOXJEHs0EtGV8YKCNIpkFLxOvE vZkKcRsmVtuZ9fVhX1iH7dYmcsCMPI8RNo47k7hHk2EG8dU+eqyPSbi4QCmErNFf DlqX+fIuiDtOkbmWcrb2qdphn6j6bMLhDaOMJGIBOmgOPi+AU9dNAfmtu1cG4u1b 2TFyUISayiwqHJQgguzvDed15fxexYdgoLB7O9t9TMbCENxisguNa5TsAN6ZkiLQ 0hY6h80xSR2kCPU= =EonA -----END PGP SIGNATURE----- Merge tag 'gfs2-v6.5-rc5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2 Pull gfs2 updates from Andreas Gruenbacher: - Fix a glock state (non-)transition bug when a dlm request times out and is canceled, and we have locking requests that can now be granted immediately - Various fixes and cleanups in how the logd and quotad daemons are woken up and terminated - Fix several bugs in the quota data reference counting and shrinking.
