[pkg-cryptsetup-devel] Bug#815480: cryptsetup: versions before 1.7.1 incompatible with latest batch of Linux kernels (mainline and stable)

[Henrique de Moraes Holschuh]

Source: cryptsetup
Severity: important
Tags: upstream fixed-upstream

This bug is actually severity grave as it renders systems unbootable and
data unaccessible, but since it can only trigger on non-Debian kernels ATM,
I am reporting it at severity important.

cryptsetup is rendered useless by the latest batch of upstream stable
kernels, as well as by Linux mainline.

On systems with encrypted root, this renders the system unbootable.
Otherwise, it renders any encrypted partitions and media unaccessible.

Reproduced in Debian stable with a custom 3.18.27 kernel.

The issue has been fixed upstream in the cryptsetup master branch, and in
the cryptsetup v1_7_x branch.  The fix will land in the 1.7.1 release, I
think.

The kernel people did not reply yet due to the weekend, but I expect the
change will be made optional or reverted... for a while (and I hope for the
"optional").

Regardless, it would be nice to have updated cryptsetup uploaded to unstable
ASAP, and an eventual Debian stable backport...
