SMB3: Fix 3.11 encryption to Windows and handle encrypted smb3 tcon
Temporarily disable AES-GCM, as AES-CCM is only currently enabled mechanism on client side. This fixes SMB3.11 encrypted mounts to Windows. Also the tree connect request itself should be encrypted if requested encryption ("seal" on mount), in addition we should be enabling encryption in 3.11 based on whether we got any valid encryption ciphers back in negprot (the corresponding session flag is not set as it is in 3.0 and 3.02) Signed-off-by: Steve French <smfrench@gmail.com> Reviewed-by: Pavel Shilovsky <pshilov@microsoft.com> Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com> CC: Stable <stable@vger.kernel.org>
