[PATCH] cifs: Fix regression during share-level security mounts (Repost)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shirish Pargaonkar <shirishpargaonkar@xxxxxxxxx>


NTLM response length was changed to 16 bytes instead of 24 bytes
that are sent in Tree Connection Request during share-level security
share mounts.  Revert it back to 24 bytes.
