Merge tag 'v7.2-rc4-smb3-server-fixes' of git://git.samba.org/ksmbd

Pull smb server fixes from Steve French:
 "This contains eight ksmbd fixes covering POSIX ACL handling, SMB
  signing enforcement, DACL parsing and construction hardening, session
  lifetime handling, and validation of malformed transform and
  compressed SMB2 requests:

   - preserve inherited POSIX ACL mask when creating objects.

   - enforce the session signing requirement for plaintext SMB requests.

   - harden DACL/ACE processing against size overflows, incomplete ACE
     copies, and undersized SIDs.

   - defer teardown of a previous session until NTLM authentication
     succeeds.

   - reject undersized encryption-transform and decompressed SMB2
     requests before they can reach normal SMB2 request processing"
