Merge tag 'cifs-for-7.4' of https://git.manguebit.org/linux

Pull smb client updates from Paulo Alcantara:

 - Implement ->fileattr_set so chattr(1) compression changes (chattr
   +c/-c) go through the generic VFS fileattr path and its permission
   and serialization checks instead of the raw FS_IOC_SETFLAGS fallback
   and remove the now-unreachable file flags ioctl handlers

 - Require stable pages when the connection is signed or SMB compression
   is enabled, so a buffered write can no longer modify a folio that is
   still in flight and corrupt its signature (surfaced as -EIO) or, with
   compression, silently corrupt the data stored on the server

 - Stop breaking a file's just-granted lease while probing it for a
   Minshall+French symlink, by reusing an already open handle or opening
   with the inode's lease key

 - Fix several out-of-bounds reads and use-after-free bug in SMB1

 - Fix an use-after-free bug in cifs_ses_add_channel()

 - Fix a NULL pointer dereference in the demultiplex thread when an
   encrypted read response matches no outstanding request and reclaim
   the credits granted on such responses to avoid starving the
   connection of credits

 - Fail sends fast when the connection needs to reconnect

 - Drop the redundant nls_table argument threaded through the session
   setup, tree connect and path-based call paths, allocate the session
   setup state on the stack and remove the internal CIFS version number
   along with a batch of write-only fields and commented-out code
