From c9f97a27ceee84998999bf3341e6d5d207b05539 Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Wed, 19 Sep 2012 09:40:30 +0300 Subject: [PATCH] crypto: x86/glue_helper - fix storing of new IV in CBC encryption Glue_helper incorrectly XORs new IV over old IV at end of CBC encryption function when it should store. This causes CBC encryption to give incorrect output on multi-page encryption requests.
