[Pkg-cryptsetup-devel] Bug#444914: temporary-cryptsetup-$$ files appear in /dev/mapper

[Dick Middleton]

Package: cryptsetup
Version: 2:1.0.5-2
Severity: important


I have a curious effect; sometimes I get an error with luksOpen such as this:

Failed to setup dm-crypt key mapping.
Check kernel for support for the aes-cbc-plain cipher spec and verify that /dev/mapper/vg02-devil contains at least 261 sectors.
Failed to read from key storage
Command failed: No key available with this passphrase.

None of these problems exist - it's a perfectly valid luks partition
so the cause remains a mystery for the moment .... however:

On a subsequent attempt to luksOpen it will most likely succeed but
there then remains a file /dev/mapper/temporary-cryptsetup-$$ where $$
is obviously a process number.  This file can be removed with a
luksClose.

To reiterate, this file remains after a subsequent successful attempt
not after the preceeding failure.

This problem has only appeared on my system after upgrading the
hardware from a k7 system to an amd64 system and changing to a Debian
stock kernel (2.6.22-2-amd64) rather than a home brew (2.6.19) one.
