Hi.
I have an external hard drive with an encrypted partition. I am using
kde so all i had to do under 2.6.23 was
"cryptsetup luksOpen /dev/sdb2 crypt-extern"
then udev/hal/kde (?)automatically created an desktop icon. i could
click this icon to mount and open the drive.
when i do the luksOpen command with v2.6.23-6597-gcfa76f0 this icon is
not created anymore.
a few commits were made in drivers/md, so it seems something broke.
config extract:
CONFIG_MD=y
# CONFIG_BLK_DEV_MD is not set
CONFIG_BLK_DEV_DM=y
# CONFIG_DM_DEBUG is not set
CONFIG_DM_CRYPT=y
CONFIG_DM_SNAPSHOT=m
CONFIG_DM_MIRROR=m
CONFIG_DM_ZERO=m
# CONFIG_DM_MULTIPATH is not set
CONFIG_DM_DELAY=m
CONFIG_DM_UEVENT=y
# CONFIG_FUSION is not set
any ideas?

Could be DM breakage, could be udev/sysfs breakage. Is it still happening
in current mainline?
And how come I'm seeing unresponded-to-for-a-week regression
reports on lkml?

There are no obvious changes, which I would expect to cause a breakage
in this area.

It works fine with 2.6.24-rc1+ and GNOME, even without any initial shell
command to set it up. Just inserting a LUKS volume, brings up a password
dialog, and then mounts all automatically.
There was a timing problem fix in HAL (in 0.5.10), maybe that is what
happens here.

Hal version is 0.5.9.1-r2.
to make things clear:
boot 2.6.23 doing "cryptsetup luksOpen /dev/sdb2 crypt-extern" -> kde
asks to mount new device
boot v2.6.24-rc1-497-gb1d08ac doing "cryptsetup luksOpen /dev/sdb2
crypt-extern" -> nothing happens in kde.
same user land, different kernel.

Yeah, but I expect it to be a timing problem, which may show up with a
new kernel. The kernel is maybe just that bit faster in the event
generation, that it triggers a silly HAL bug. You probably need:
http://gitweb.freedesktop.org/?p=hal.git;a=commit;h=f3e160d0ab85f62b76400cb521b4d1b5813d0711
It's all fine here regarding LUKS volumes, therefore I wouldn't know
what would be wrong at the kernel side.

Yes. With hal-0.5.10 (which includes above commit) the new kernel
behaves like 2.6.23 again.
