Package: libpam-mount
Version: 0.9.25-1
Severity: important
I'm not sure if this is a bug with xdm or with libpam-mount, but I
thought I would submit this bug against libpam-mount, since I think you
might be more familiar with the cause of the problem.
Since I upgraded from xdm 4.3.0.dfsg.1-12.0.1 to 6.8.2.dfsg.1-5 (another
bug prevented me from using versions in between), libpam-mount no longer
mounts my encrypted partition. Logging in from the text console works.
Enabling debugging, and comparing the logs from logging in with the
console, and logging in from xdm, it seems that under xdm, pam_mount is
adding an extra argument at the end of command lines:
On log in:
- from the console:
pam_mount: command: /bin/mount [-t] [crypt] [-ocipher=twofish,hash=sha512]
[/dev/hda8] [/home/hubert]
and
pam_mount: command: /usr/sbin/pmvarrun [-u] [hubert] [-d] [-o] [1]
- from xdm:
pam_mount: command: /bin/mount [-t] [crypt] [-ocipher=twofish,hash=sha512]
[/dev/hda8] [/home/hubert] [clientWindow]
and
pam_mount: command: /usr/sbin/pmvarrun [-u] [hubert] [-d] [-o] [1]
[statusAttributes]
On log out:
- from the console:
pam_mount: command: /usr/sbin/pmvarrun [-u] [hubert] [-d] [-o] [-1]
and
pam_mount: command: /usr/sbin/lsof [/home/hubert]
- from xdm:
pam_mount: command: /usr/sbin/pmvarrun [-u] [hubert] [-d] [-o] [-1]
[statusAttributes]
and
pam_mount: command: /usr/sbin/lsof [/home/hubert] [createHook]
(for log out, the umount.crypt command line seems to be the same for
logging out from the console and from xdm)
The extra command line arguments seem to be consistent across runs of
xdm.
I can send more complete logs if needed.
The only difference between my /etc/security/pam_mount.conf and the one
shipped in the package is that mkmountpoint is set to 0, and of course I
have a line to set up my mount point:
volume hubert crypt - /dev/hda8 /home/hubert cipher=twofish,hash=sha512
aes-256-ecb /home/hubert.key
