From 644f65afe1d4f11f7c878404640da8f8b014a446 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sat, 28 Apr 2018 22:08:09 +0200 Subject: [PATCH] apm821xx: backport and reassign crypto4xx patches This patch backports several patches that went upstream into Herbert Xu's cryptodev-2.6 tree: crypto: Use zeroing memory allocator instead of allocator/memset crypto: crypto4xx - performance optimizations crypto: crypto4xx - convert to skcipher crypto: crypto4xx - avoid VLA use crypto: crypto4xx - add aes-ctr support crypto: crypto4xx - properly set IV after de- and encrypt crypto: crypto4xx - extend aead fallback checks crypto: crypto4xx - put temporary dst sg into request ctx The older, outstanding patches from 120-wxyz series have been upstreamed as well and therefore they have been reassigned to fit into the series.
