From 2918aa8d1d4e7b4586a5a89dc8406e1d431f5129 Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Sat, 29 Jan 2011 15:14:01 +1100 Subject: crypto: testmgr - mark xts(aes) as fips_allowed We (Red Hat) are intending to include dm-crypt functionality, using xts(aes) for disk encryption, as part of an upcoming FIPS-140-2 certification effort, and xts(aes) *is* on the list of possible mode/cipher combinations that can be certified. To make that possible, we need to mark xts(aes) as fips_allowed in the crypto subsystem. A 'modprobe tcrypt mode=10' in fips mode shows xts(aes) self-tests passing successfully after this change.

Well, gcm(aes) self-tests currently fail in fips mode, as gcm is dependent on ghash, which semi-recently got self-test vectors added, but wasn't marked as a fips_allowed algorithm. Because of gcm's dependence on what is now seen as a non-fips_allowed algorithm, its self-tests refuse to run. Previously, ghash got a pass in fips mode, due to the lack of any test vectors at all, and thus gcm self-tests were able to run. After this patch, a 'modprobe tcrypt mode=35' no longer panics in fips mode, and successful self-test of gcm(aes) is reported.
