[pkg-cryptsetup-devel] Bug#532579: cryptsetup: fails to resume from lvm on crypt when resume device is /dev/dm-X

[Evgeni Golov]

Package: cryptsetup
Version: 2:1.0.6+20090405.svn49-1
Severity: normal

Hi,

I have the following setup on my laptop:
hda1 plain root
hda2 luks with lvm ontop
lvm1 swap
lvm2 home

I use the passdev script and LABELs/UUIDs everywhere.

fstab:
LABEL=root	/		ext3		noatime,errors=remount-ro	0	1
LABEL=swap	none		swap		sw		0	0
LABEL=home	/home		ext3		noatime		0	0

crypttab:
crypt	UUID=44dd50d4-e9a0-4bbf-8ba3-29434e77dba3 \
	/dev/disk/by-label/usbext3:/keyfile-chiisai.luks \
	luks,keyscript=/lib/cryptsetup/scripts/passdev,tries=1

/proc/cmdline:
BOOT_IMAGE=/boot/vmlinuz-2.6.30-rc8-686 root=UUID=be7763cd-158a-4d70-bfb7-557363fb968b ro quiet splash hpet=force

My swap can be accessed via /dev/mapper/vg--crypt-swap or /dev/dm-1.
uswsusp enters /dev/dm-1 in /etc/uswsusp.conf and that seems to break cryptsetup
(I think in canonical_device()). When I manually add /dev/mapper/... to
/etc/initramfs-tools/conf.d/resume everything is ok, and my system can resume,
but when it's not there, cryptsetup thinks it has nothing to do, does not copy
passdev and conf.d/cryptroot to the initramfs and my system cant resume.

Is there anything cryptsetup could do about this?

Regards
Evgeni
