Package: libpam-mount
Version: 0.21-1
Severity: normal
Hi, Bastian,
i have a crash in cryptsetup when logging in to the user account
with the following ~/.pam-mount.conf.xml.
(no changes since my last bug reports:
a encrypted luks filesystem image mounted inside the home directory)
<?xml version="1.0" encoding="UTF-8"?>
<pam_mount>
<volume
user="ingo"
path="/home/ingo:crypt.img"
mountpoint="/home/ingo/crypt"
fstype="crypt"
options="fsck,nodev,loop,nosuid"
fskeycipher=""
fskeypath=""
invert="0"
server="0" />
</pam_mount>
Here the tail of the console log for version 21-1
with '-x' option set in /sbin/mount.crypt:

After the segfault the two loop devices remain
(or is it only one, displayed twice):
noo:~ # losetup -a
/dev/loop0: [0309]:22 (/home/ingo:crypt.img)
/dev/loop/0: [0309]:22 (/home/ingo:crypt.img)
noo:~ # losetup -d /dev/loop0
noo:~ # losetup -a
noo:~ #
hope all this stuff helps.
