Subject: [PATCH 7/8] tcrypt: disable 384 bit key XTS test
Date: Tue, 19 Apr 2011 21:29:20 +0200	[thread overview]
Message-ID: <20110419193250.074519442@linux.vnet.ibm.com> (raw)
In-Reply-To: 20110419192913.888086020@linux.vnet.ibm.com

[-- Attachment #1: crypto-disable_xts_wrong_key_test.patch --]
[-- Type: text/plain, Size: 1256 bytes --]

From: Jan Glauber <jang@linux.vnet.ibm.com>

XTS mode is only defined for 256 and 512 bit key lengths. s390 only
implements these two modes and running the test with a 384 bit key
will stop the speed test with an error. Remove the superfluous key
lenght.
