Description robert spitzenpfeil 2024-02-22 15:47:11 UTC

TW version: "20240220"


this always fails:
------------------

mount -t cifs //server/share/A -o,username=admin,dom=domain,ro

error: "kernel: CIFS: VFS: cifs_read_super: get root inode failed"



this works:
-----------

mount -t cifs //server/share -o,username=admin,dom=domain,ro

mount -t cifs //server/share/A/B -o,username=admin,dom=domain,ro



Doing the exact same thing always works with 

* Leap 15.5 (live image: openSUSE-Leap-15.5-KDE-Live-x86_64-Build13.15-Media)
* Debian 12


Mounting as show above used to work with TW, for some time now it doesn't. The last time I had a successful mount was 2023-09-16, so the change must have happened after that. File permissions on the share haven't changed in ages.
