CIFS mount doesn't work since kernel v5.15.10

[isadora]

With kernel v5.15.10, mount.cifs doesn't work and return :

Code: Select all

mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)


In journalclt, kernel log :

Code: Select all

kernel: Couldn't init compat dev. ret -12

When I downgrade to kernel v5.15.6, all works. I have about 10 PC that have the same problem. Samba server works nice. So I think it's a kernel or a cifs-utils problem. Do someone have the same problem ?

There's an update candidate for 5.15.11 in updates_testing, have a look at https://bugs.mageia.org/show_bug.cgi?id=29813
This also includes a fix for the recent cifs userspace update, check https://bugs.mageia.org/show_bug.cgi?id=29641#c45 for context.

Although going by the error message, https://bugs.mageia.org/show_bug.cgi?id=29784 looks similar - did you report that ?

With kernel 5.15.11, I have the same problem and yes, it's the same bug report as here : https://bugs.mageia.org/show_bug.cgi?id=29784
I downgraded to kernel 5.15.6 and it works. May be with kernel 5.15.12, it will work !
Thank you for your help and happy new year !

After kernel update to 5.15.11 I have the same issue. I can confirm that with kernel 5.15.6 cifs mounting is OK.

Could you try 5.15.12 in testing?

I've been following this thread with interest as I use Samba frequently.

I installed kernel 5.15.12-desktop-2.mga8 from updates-testing as suggested.

I can confirm that with the:

Code: Select all

mount -t cifs //server1/machines /home/******/mnt -o username=******,uid=1000

version of the cifs mount command it works well.

Too late to test any more tonight.

I can also confirm that with the general release of kernel 5.15.15-desktop-1.mga8 today, the alterations have been carried forward and as far as simple testing goes the cifs mount command works OK.

Thanks.

Thank you for the feedback!

@lerevecbeau, could you edit your initial post and prepend [SOLVED] to the subject?
