Subject: [PATCH 0/6] cifs: Fix connections over NetBIOS session

This patch series fixes establishment of NetBIOS session for SMB2+
connections which is currently broken. Tested with SMB3 dialect
against Windows Server 2022.

Also it improves autodetection whether NetBIOS session is needed on
specified server port, and allows to initialize NetBIOS session also
over other port than 139. This is needed when testing against virtual
machines when port 139 is forwarded over some non-system port.

Pali Rohár (6):
  cifs: Allow to disable or force initialization of NetBIOS session
  cifs: Fix establishing NetBIOS session for SMB2+ connection
  cifs: Improve establishing SMB connection with NetBIOS session
  cifs: Improve handling of NetBIOS packets
  cifs: Fix negotiate retry functionality
  cifs: Set default Netbios RFC1001 server name to hostname in UNC
