From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx> This patch has been added to the 4.1 stable tree. If you have any objections, please let us know. =============== [ Upstream commit a0118c8b2be9297aed8e915c60b4013326b256d4 ] Since 6de62f15b581 ("crypto: algif_hash - Require setkey before accept(2)"), the AF_ALG interface requires userspace to provide a key to any algorithm that has a setkey method. However, the non-HMAC algorithms are not keyed, so setting a key is unnecessary. Fix this by removing the setkey method from the non-keyed hash algorithms.
