Package: linux-patch-tuxonice
Version: 3.0.1+2.6.30-2
Severity: critical
Justification: causes serious data loss
Hi
it seems that tuxonice on resuming does not check if mounted partitions have
been accessed since last hibernating. Thus people will suffer from data loss if
they hibernate and, for example, boot another operating system, access
partitions and resume the hibernated system afterwards. You could say that
people should know that they should not access partitions which are in use by a
hibernated system, but even if you are careful there is still a risk of loosing
data, as the following example shows, where an unlucky interaction of patched
kernel, unpatched kernel and grub corrupted my root partition.
I have a self-compiled and tuxonice-patched kernel (2.6.30) installed which I
usually run and I have a standard debian kernel installed without tuxonice. Now
the following happened:
1. apt-get upgraded the package linux-image-2.6-686 and installed a new major
kernel version (linux-image-2.6.32-trunk-686). The new kernel was added to the
grub configuration and due to that my "default" setting in grub did not point
on my self-compiled kernel any more, but it pointed on an unpatched kernel.
2. Some hours later I hibernated using tuxonice.
3. On the next day I accidently booted the unpatched kernel which had become
default selection in grub. Thus my desktop was not resumed which didn't seem to
be a problem. I just lost my open desktop windows. What I didn't realize at
that time was the fact, that upon booting, linux didn't activate the swap
partition, because there was still the tuxonice image in the swap and the
unpatched kernel refused to activate the swap as it didn't look like a swap
partition to the kernel. So the swap partition was left untouched.
4. On the next day I booted the tuxonice-patched kernel and it resumed the
image that it found in the swap space. I didn't realize that fast enough and
when my desktop reappeared I realized that something was wrong and I did a hard
reboot, but at that time it was already too late. My system then booted into
emergency shell and I had to run e2fsck manually. There were several files
destroyed, distributed all over the filesystem.
Fortunately I had a backup of my home and debsums helped me with the rest. I
think tuxonice should somehow check if mounted partitions have been accessed
inbetween, before resuming. If this is not possible then there should maybe be
a init.d script which checks if the swap space could not be activated due to a
tuxonice signature in swap and delete it.
