Subject: initscripts: /etc/init.d/umountfs segfaults on shutdown

Package: initscripts
Version: 2.86-5
Severity: critical
Justification: causes serious data loss

The script /etc/init.d/umountfs segfaults on shutdown. Due to this, the
swap and all other filesystems are not cleanly unmounted which may cause
severe data loss.

I could verify this behaviour on two different systems, both running the
ReiserFS filesystem and Debian unstable. On a third box that is running
the latest version of Debian Sarge and EXT3 it could not be reproduced,

The error message during shutdown is similar to this one:

Deactivating swap...umount: none busy - remounted read-only
Segmentation fault
done.
Unmounting local filesystems...umount: none busy - remounted read-only
Segmentation fault
done.
mount: / is busy

Bye
Alexander

This (#284016) is presumably the same issue as #283323.

umount should not segfault.

However, we should also see if we can find a workaround in the
initscript.

I can't think of a workaround, but if this will not be fixed in time for
sarge I will just disable the udev-mtab init script in the udev package.

Duplicate Ubuntu bug.

It is quite serious -- causes all my filesystems to come back unclean...

This was (apparently) fixed in the 2.12j release of mount.

With the latest mount, it does seem to unmount cleanly, and the seg faults are
gone, but the "umount: none busy" message still appears for each mount.

Marking as duplicate based on debbugs merge (283323,284016)

This bug has been marked as a duplicate of bug 10790.
