Description:

Mounting a CIFS share via mount.cifs with the 'guest' option does not work in Linux kernel v4.6.3:

# mount -o guest //{cifs_share} {mount-point}

The command fails with:

mount error(22): Invalid argument

The 'invalid argument' appears to be 'guest' Omitting the '-o guest' portion causes the command to succeed but it prompts for a password.

Previously, under kernel v4.5.4, the above command would succeed and not prompt for a password.

Additional info:

cifs-utils 6.5
linux 4.6.3

Steps to reproduce:

Attempt to mount a CIFS share using the 'guest' option as documented in mount.cifs(8):

# mount.cifs -o guest //{cifs_share} {mount-point}
This task depends upon
