2014-11-24crypto: prefix module autoloading with "crypto-"Kees Cook1-4/+4
This prefixes all crypto module loading with "crypto-" so we never run the risk of exposing module auto-loading to userspace via a crypto API, as demonstrated by Mathias Krause: https://lkml.org/lkml/2013/3/4/70 Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2014-06-20crypto: des_3des - add x86-64 assembly implementationJussi Kivilinna1-0/+509
Patch adds x86_64 assembly implementation of Triple DES EDE cipher algorithm. Two assembly implementations are provided. First is regular 'one-block at time' encrypt/decrypt function. Second is 'three-blocks at time' function that gains performance increase on out-of-order CPUs. tcrypt test results: Intel Core i5-4570: des3_ede-asm vs des3_ede-generic: size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec 16B 1.21x 1.22x 1.27x 1.36x 1.25x 1.25x 64B 1.98x 1.96x 1.23x 2.04x 2.01x 2.00x 256B 2.34x 2.37x 1.21x 2.40x 2.38x 2.39x 1024B 2.50x 2.47x 1.22x 2.51x 2.52x 2.51x 8192B 2.51x 2.53x 1.21x 2.56x 2.54x 2.55x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
