Merge tag 'v7.2-rc-part1-ksmbd-fixes' of git://git.samba.org/ksmbd

Pull smb server updates from Steve French:

 - Use after free fixes

 - Out of bounds read fix

 - Add SMB compression support both at rest and over the wire: support
   decompression of compressed SMB2 requests, initially allow compressed
   SMB2 READ responses, and implement get/set compression operations for
   per-file compression state.

 - Credentials fixes: for various FSCTLs, setinfo, delete on close and
   for alternate data streams

 - Fix access checks and permission checks in DUPLICAT_EXTENTS and
   SET_ZERO_DATA fsctls, find_file_posix_info, FILE_LINK_INFORMATION and
   smb2_set_info_sec

 - Reject non valid session in compound request

 - Serialize QUERY_DIRECTORY

 - Prevent path traversal bypass by restricting caseless retry

 - Path lookup fix

 - Two minor cleanup fixes
