mount.cifs stopped working with protocol version != 1.0
Status in linux package in Ubuntu:
On a Xenial installation after upgrading to the HWE 4.13.0-32-generic
kernel it is not possible to use mount.cifs with -o vers=x.y different
Steps to reproduce:
1. Setup a local Samba share with ntlm auth = yes.
mount.cifs -o user=<myuser>,sec=ntlm,vers=2.0 //localhost/theshare/
3. This may be repeated for the following versions: 2.0, 2.1, 3.0.
The share gets mounted at /mnt/theshare.
The share is not mounted, this gets printed in the console:
mount error(22): Invalid argument
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
and in dmesg:
[ 61.935687] CIFS VFS: Unable to select appropriate authentication method!
[ 61.935689] CIFS VFS: Send error in SessSetup = -22
[ 61.935744] CIFS VFS: cifs_mount failed w/return code = -22
