Description Milan Broz 2010-12-06 17:09:19 UTC

+++ This bug was initially created as a clone of Bug #553411 +++
Clone of #636208 - dm-crypt part.

- dm-crypt code need to understand aes-xts-plain and aes-xts-plain64 (xts mode and plain/plain64 IV)

How reproducible:

--- Additional comment from dlehman on 2010-01-11 12:19:01 EST ---

We started using a different cipher in Fedora 11 or 12 (aes-xts-plain). RHEL5 installer runtime environment does not include the kernel modules needed to use this cipher.

Nb: this patch was at least temporarily reverted, due to a userspace change being required to properly support unlocking encrypted volumes at boot time. Moving bug back to POST.

cryptsetup-luks-1.0.3-8.el5
kernel-2.6.18-269.el5

1. The LUKS partitioned created by RHEL6 (cryptsetup -c aes-xts-plain64 -s 512 luksFormat /dev/sda) successfully opened by RHEL5. md5sum make sure data integrity.

2. LUKS partition created by RHEL5 (aes-xts-plain64) successfully opened by RHEL6. md5sum make sure data integrity.
