858e74876c smb: client: parse owner/group when creating reparse points 
Parse owner/group when creating special files and symlinks under
SMB3.1.1 POSIX mounts.

Move the parsing of owner/group to smb2_compound_op() so we don't have
to duplicate it in both smb2_get_reparse_inode() and
smb311_posix_query_path_info().

76025cc228 smb: client: fix parsing of SMB3.1.1 POSIX create context 
The data offset for the SMB3.1.1 POSIX create context will always be
8-byte aligned so having the check 'noff + nlen >= doff' in
smb2_parse_contexts() is wrong as it will lead to -EINVAL because noff
+ nlen == doff.

Fix the sanity check to correctly handle aligned create context data.

7f738527a7 cifs: new nt status codes from MS-SMB2 
MS-SMB2 spec has introduced two new status codes,
STATUS_SERVER_UNAVAILABLE and STATUS_FILE_NOT_AVAILABLE
which are to be treated as retryable errors.

This change adds these to the available mappings and
maps them to Linux errno EAGAIN.

268b8b5797 cifs: pick channel for tcon and tdis 
Today, the tree connect and disconnect requests are
sent on the primary channel only. However, the new
multichannel logic allows the session to remain active
even if one of the channels are alive. So a tree connect
can now be triggered during a reconnect on any of
its channels.

This change changes tcon and tdis calls to pick an
active channel instead of the first one.

936eba9cfb cifs: open_cached_dir should not rely on primary channel 
open_cached_dir today selects ses->server a.k.a primary channel
to send requests. When multichannel is used, the primary
channel maybe down. So it does not make sense to rely only
on that channel.

This fix makes this function pick a channel with the standard
helper function cifs_pick_channel.

d8392c203e smb3: show beginning time for per share stats 
In analyzing problems, one missing piece of debug data is when the
mount occurred.  A related problem is when collecting stats we don't
know the  period of time the stats covered, ie when this set of stats
for the tcon started to be collected.  To make debugging easier track
the stats begin time. Set it when the mount occurred at mount time,
and reset it to current time whenever stats are reset. For example,

...
1) \\localhost\test
SMBs: 14 since 2024-01-17 22:17:30 UTC
Bytes read: 0  Bytes written: 0
Open files: 0 total (local), 0 open on server
TreeConnects: 1 total 0 failed
TreeDisconnects: 0 total 0 failed
...
2) \\localhost\scratch

Bytes read: 0  Bytes written: 0
Open files: 0 total (local), 0 open on server
TreeConnects: 1 total 0 failed
TreeDisconnects: 0 total 0 failed
...

Note the time "since ... UTC" is now displayed in /proc/fs/cifs/Stats
for each share that is mounted.

 ecryptfs from inadvertently mounting case-insensitive filesystems that

 As a side note, the optimization to the case-insensitive comparison code
 that you suggested, and the negative dentry support are still on the
 list, and were postponed to the next release.

6434eade5d Hi, 
Just a couple fixes and no new features. I've been reviewing and testing
 TPM patches for encrypted and integrity protected commuinications [1] but
 they did not made yet to this release.
 
 This was also first release I tested with my still heavily in-development
 test suite for linux integrity [2]. I'm refining this at the moment
 to run keyutils test suite, which could be potentially also run by a Gitlab
 runner for keyutis repository.

68da4c44b9 ext4: fix inconsistent between segment fstrim and full fstrim 
Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with
mininum length of trimmed range set to 8 blocks. If we have say a range of
blocks 10-22 free, this range will not be trimmed because it straddles the
boundary of the two FITRIM ranges and neither part is big enough. This is a
bit surprising to some users that call FITRIM on smaller ranges of blocks
to limit impact on the system. Also XFS trims all free space extents that
overlap with the specified range so we are inconsistent among filesystems.
Let's change ext4_try_to_trim_range() to consider for trimming the whole
free space extent that straddles the end of specified range, not just the
part of it within the range.

1f6bc02f18 ext4: fallback to complex scan if aligned scan doesn't work 
Currently in case the goal length is a multiple of stripe size we use
ext4_mb_scan_aligned() to find the stripe size aligned physical blocks.
In case we are not able to find any, we again go back to calling
ext4_mb_choose_next_group() to search for a different suitable block
group. However, since the linear search always begins from the start,
most of the times we end up with the same BG and the cycle continues.

With large fliesystems, the CPU can be stuck in this loop for hours
which can slow down the whole system. Hence, until we figure out a
better way to continue the search (rather than starting from beginning)
in ext4_mb_choose_next_group(), lets just fallback to
ext4_mb_complex_scan_group() in case aligned scan fails, as it is much
more likely to find the needed blocks.

7c784d6248 ext4: allow for the last group to be marked as trimmed 
The ext4 filesystem tracks the trim status of blocks at the group
level.  When an entire group has been trimmed then it is marked as
such and subsequent trim invocations with the same minimum trim size
will not be attempted on that group unless it is marked as able to be
trimmed again such as when a block is freed.

Currently the last group can't be marked as trimmed due to incorrect
logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
to return the zero based index of the last cluster in a group. This is
then used by ext4_try_to_trim_range() to determine if the trim
operation spans the entire group and as such if the trim status of the
group should be recorded.

ext4_last_grp_cluster() takes a 0 based group index, thus the valid
values for grp are 0..(ext4_get_groups_count - 1). Any group index
less than (ext4_get_groups_count - 1) is not the last group and must
have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
to calculate the number of clusters based on the number of blocks in
the group. Finally subtract 1 from the number of clusters as zero
based indexing is expected.  Rearrange the function slightly to make
it clear what we are calculating and returning.

Reproducer:
// Create file system where the last group has fewer blocks than
// blocks per group
$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
$ mount /dev/nvme0n1 /mnt

Before Patch:
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group not marked as trimmed so second invocation still discards blocks
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed

After Patch:
fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group marked as trimmed so second invocation DOESN'T discard any blocks
fstrim -v /mnt
/mnt: 0 B (0 bytes) trimmed

Pull afs updates from David Howells:
 "The majority of the patches are aimed at fixing and improving the AFS
  filesystem's rotation over server IP addresses, but there are also
  some fixes from Oleg Nesterov for the use of read_seqbegin_or_lock().

   - Fix fileserver probe handling so that the next round of probes
     doesn't break ongoing server/address rotation by clearing all the
     probe result tracking. This could occasionally cause the rotation
     algorithm to drop straight through, give a 'successful' result
     without actually emitting any RPC calls, leaving the reply buffer
     in an undefined state.

     Instead, detach the probe results into a separate struct and
     allocate a new one each time we start probing and update the
     pointer to it. Probes are also sent in order of address preference
     to try and improve the chance that the preferred one will complete
     first.

   - Fix server rotation so that it uses configurable address
     preferences across on the probes that have completed so far than
     ranking them by RTT as the latter doesn't necessarily give the best
     route. The preference list can be altered by writing into
     /proc/net/afs/addr_prefs.

   - Fix the handling of Read-Only (and Backup) volume callbacks as
     there is one per volume, not one per file, so if someone performs a
     command that, say, offlines the volume but doesn't change it, when
     it comes back online we don't spam the server with a status fetch
     for every vnode we're using. Instead, check the Creation timestamp
     in the VolSync record when prompted by a callback break.

   - Handle volume regression (ie. a RW volume being restored from a
     backup) by scrubbing all cache data for that volume. This is
     detected from the VolSync creation timestamp.

   - Adjust abort handling and abort -> error mapping to match better
     with what other AFS clients do.

   - Fix offline and busy volume state handling as they only apply to
     individual server instances and not entire volumes and the rotation
     algorithm should go and look at other servers if available. Also
     make it sleep briefly before each retry if all the volume instances
     are unavailable"

Pull btrfs updates from David Sterba:
 "There are no exciting changes for users, it's been mostly API
  conversions and some fixes or refactoring.

  The mount API conversion is a base for future improvements that would
  come with VFS. Metadata processing has been converted to folios, not
  yet enabling the large folios but it's one patch away once everything
  gets tested enough.

  Core changes:

   - convert extent buffers to folios:
      - direct API conversion where possible
      - performance can drop by a few percent on metadata heavy
        workloads, the folio sizes are not constant and the calculations
        add up in the item helpers
      - both regular and subpage modes
      - data cannot be converted yet, we need to port that to iomap and
        there are some other generic changes required

   - convert mount to the new API, should not be user visible:
      - options deprecated long time ago have been removed: inode_cache,
        recovery
      - the new logic that splits mount to two phases slightly changes
        timing of device scanning for multi-device filesystems
      - LSM options will now work (like for selinux)

   - convert delayed nodes radix tree to xarray, preserving the
     preload-like logic that still allows to allocate with GFP_NOFS

   - more validation of sysfs value of scrub_speed_max

   - refactor chunk map structure, reduce size and improve performance

   - extent map refactoring, smaller data structures, improved
     performance

   - reduce size of struct extent_io_tree, embedded in several
     structures

   - temporary pages used for compression are cached and attached to a
     shrinker, this may slightly improve performance

   - in zoned mode, remove redirty extent buffer tracking, zeros are
     written in case an out-of-order is detected and proper data are
     written to the actual write pointer

   - cleanups, refactoring, error message improvements, updated tests

   - verify and update branch name or tag

   - remove unwanted text"

41daf06ea1 linux_kselftest-kunit-6.8-rc1 
This KUnit update for Linux 6.8-rc1 consists of:
 
 - a new feature that adds APIs for managing devices introducing
   a set of helper functions which allow devices (internally a
   struct kunit_device) to be created and managed by KUnit.
   These devices will be automatically unregistered on
   test exit. These helpers can either use a user-provided
   struct device_driver, or have one automatically created and
   managed by KUnit. In both cases, the device lives on a new
   kunit_bus.
 
 - changes to switch drm/tests to use kunit devices
 
 - several fixes and enhancements to attribute feature
 
 - changes to reorganize deferred action function introducing
   KUNIT_DEFINE_ACTION_WRAPPER
 
 - new feature adds ability to run tests after boot using debugfs
 
 - fixes and enhancements to string-stream-test:
   - parse ERR_PTR in string_stream_destroy()
   - unchecked dereference in bug fix in debugfs_print_results()
   - handling errors from alloc_string_stream()

Pull power management updates from Rafael Wysocki:
 "These add support for new processors (Sierra Forest, Grand Ridge and
  Meteor Lake) to the intel_idle driver, make intel_pstate run on
  Emerald Rapids without HWP support and adjust it to utilize EPP values
  supplied by the platform firmware, fix issues, clean up code and
  improve documentation.

  The most significant fix addresses deadlocks in the core system-wide
  resume code that occur if async_schedule_dev() attempts to run its
  argument function synchronously (for example, due to a memory
  allocation failure). It rearranges the code in question which may
  increase the system resume time in some cases, but this basically is a
  removal of a premature optimization. That optimization will be added
  back later, but properly this time.

Pull thermal control updates from Rafael Wysocki:
 "These add support for the D1/T113s THS controller to the sun8i driver
  and a DT-based mechanism for platforms to indicate a preference to
  reboot (instead of shutting down) on crossing a critical trip point,
  fix issues, make other improvements (in the IPA governor, the Intel
  HFI driver, the exynos driver and the thermal netlink interface among
  other places) and clean up code.

  One long-standing issue addressed here is that trip point crossing
  notifications sent to user space might be unreliable due to the
  incorrect handling of trip point hysteresis in the thermal core:
  multiple notifications might be sent for the same event or there might
  be events without any notification at all.

     trip point crossing notifications from being sent at incorrect
     times or not at all in some cases (Rafael J. Wysocki)

     places in the thermal core (Rafael J. Wysocki)

   - Make all trip point updates (via sysfs as well as from the platform
     firmware) trigger trip change notifications (Rafael J. Wysocki)

   - Drop redundant code from the thermal core and make one function in
     it take a const pointer argument (Rafael J. Wysocki)"
