Package: loop-aes-source
Version: 3.0d-4
Severity: normal
Hi,
if the loop-aes-module is compiled with keyscrubbing enabled,
it crashes when it's inserted into a kernel running inside a
xen-domain. Everything works fine in xen when KEYSCRUB=n is used.
KEYSCRUB should be set to 'n' by default in debian/rules when a
xen kernel ist built.
A snapshot of the crash:
# modprobe loop
loop: AES key scrubbing enabled
loop: loaded (max 8 devices)
# dd if=/dev/zero of=/tmp/xxx bs=1024 count=$((30*1024))
# losetup -e AES256 -H sha512 -S test /dev/loop0 /tmp/xxx
