commit 7aa8804c0b67b3cb263a472d17f2cb50d7f1a930 upstream. There is racy issue between smb2 session log off and smb2 session setup. It will cause user-after-free from session log off. This add session_lock when setting SMB2_SESSION_EXPIRED and referece count to session struct not to free session while it is being used.
