Subject: cifs: silence printk when establishing first session on
socket
From: Jeff Layton <[email protected]>
commit 9c4843ea576107a3c1fb94f2f758f198e9fe9e54 upstream.
When signing is enabled, the first session that's established on a
socket will cause a printk like this to pop:
CIFS VFS: Unexpected SMB signature
This is because the key exchange hasn't happened yet, so the signature
field is bogus. Don't try to check the signature on the socket until the
first session has been established. Also, eliminate the specific check
for SMB_COM_NEGOTIATE since this check covers that case too.
