Public bug reported:
Hello,
there seems to be a bug in libpam-mount in version 2.16-10 used in
Ubuntu 20.04.
I want to mount a cifs volume with a regex condition.
<volume fstype="cifs" server="server.example.com" path="folder/%(USER)"
mountpoint="/home/%(USER)/SUBFOLDER_%(USER)"
options="domain=DOMAIN,dir_mode=0700,file_mode=0700">
<and>
<user regex="yes">^[a-z]{3}.*$</user>
</and>
</volume>
At system start the system freezes completely. Then I retested during a
running session on the command line and I'm getting the error message
Segmentation fault
when I login to another user.
If I remove the 'regex="yes"' everything works.
If I remove the "and" condition everything works.
If I downgrade the libpam-mount package to version 2.16-3ubuntu0.1 of Ubuntu
18.04 everything works including using the regex condition. In Ubuntu 18.04
everything worked fine as well.
Best regards
Daniel
