cryptmount reports segfault in dmesg

[vbargsten]

Binary package hint: cryptmount

I have a LUKS encrypted data partition and want it to mount it at boot, ideally before fstab. As there are problems with cryptsetup password promt etc with ubuntu 9.10, I tried to use cryptmount instead.

/etc/cryptmount/cmtab content:
data {
      keyformat=luks
      dev=/dev/sda6
      keyfile=/dev/sda6
      dir=/data
      fstype=ext3
      }

In /etc/default/cryptmount, I tried both
CM_EARLYDV="data"
and
CM_BOOTDV="data"
and together.

Problem:
dmesg | grep crypt
[ 14.988099] cryptmount[882]: segfault at 0 ip 00be4f43 sp bfe707cc error 4 in libc-2.10.1.so[b72000+13e000]
[ 16.411724] cryptmount[1143]: segfault at 0 ip 009b5f43 sp bfb3771c error 4 in libc-2.10.1.so[943000+13e000]

Manually starting

sudo /etc/init.d/cryptmount start
[sudo] password for vb:
Starting cryptmount targets (hit shift/ctrl if short of entropy):
Bitte geben Sie das Passwort für das Ziel »data« ein:
sh: /sbin/udevsettle: not found
vb@vbmobil:~$

mounts data successfully. Btw., there seems to be a problem with udevsettle (not available anymore?)

System is Xubuntu 9.10, Kernel 2.6.31-15-generic, cryptmount cryptmount-4.0
I can do further debugging if required, though the problem is the segfault occurs on boot only.

I rolled back to kernel 2.6.28-16-generic as this allows me to boot, unlock and mount LUKS partitions successfully. All kernel releases since have the same bug.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner.

There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test the current Ubuntu development version (10.10). If you can test it, and it is still an issue, we would appreciate if you could upload updated logs by running apport-collect 488437, and any other logs that are relevant for this particular issue.
