From 03b56ce54143a3a69d4fea6ff8130b1c903a47ce Mon Sep 17 00:00:00 2001 From: Jarod Wilson Date: Thu, 18 Jun 2009 19:52:59 +0800 Subject: [PATCH] crypto: des_s390 - Permit weak keys unless REQ_WEAK_KEY set Just started running fips cavs test vectors through an s390x system for giggles, and discovered that I missed patching s390's arch-specific des3 implementation w/an earlier des3 patch to permit weak keys. This change adds the same flag tweaks as ad79cdd77fc1466e45cf923890f66bcfe7c43f12 (crypto: des3_ede - permit weak keys unless REQ_WEAK_KEY set) for s390's des3 implementation, yields expected test results now.
