Title: kernel 4.4.0.97.102 breaks DFS Status in Linux: Fix Released Status in linux package in Ubuntu: Confirmed Bug description: OS: Ubuntu Desktop 16.04.3 We connect to Windows DFS using automounter with our Linux 16.04 workstations to let users access the windows shares. Until kernel version 4.4.0-96 this worked without any issues. However if a computer updates to kernel 4.4.0.97.102, using the same configs and samba version, it stops working and reports a "ls: cannot access xx: File name too long" error. (where xx is a foldername) Also if you run "ls -all" you will see: d????????? ? ? ? ? ?
