  ksmbd: reject undersized decompressed SMB2 requests (2026-07-22
09:54:10 -0500)

----------------------------------------------------------------
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.
