From 65d5fcf5c284735d3a4254cb17691842385984bb Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 17 Sep 2012 19:57:30 -0700 Subject: [PATCH] sparc64: Fix IV handling bug in des_sparc64_cbc_decrypt The IV wasn't being propagated properly past the first loop iteration. This bug lived only because the crypto layer tests for cbc(des) do not have any cases that go more than one loop. Signed-off-by: David S.
