crypto: sha512-mb - fix ctx pointer

2016-08-16T09:09:43Z

1. fix ctx pointer Use req_ctx which is the ctx for the next job that have been completed in the lanes instead of the first completed job rctx, whose completion could have been called and released. Signed-off-by: Xiaodong Liu Signed-off-by: Herbert Xu

crypto: sha256-mb - fix ctx pointer and digest copy

2016-08-16T09:09:42Z

1. fix ctx pointer Use req_ctx which is the ctx for the next job that have been completed in the lanes instead of the first completed job rctx, whose completion could have been called and released. 2. fix digest copy Use XMM register to copy another 16 bytes sha256 digest instead of a regular register.

crypto: sha-mb - Cleanup code to use || instead of |

2016-07-12T05:02:00Z

for condition comparison and cleanup multiline comment style In sha*_ctx_mgr_submit, we currently use the | operator instead of || ((ctx->partial_block_buffer_length) | (len < SHA1_BLOCK_SIZE)) Switching it to || and remove extraneous paranthesis to adhere to coding style. Also cleanup inconsistent multiline comment style. Signed-off-by: Tim Chen Signed-off-by: Herbert Xu

crypto: aesni - Use crypto_cipher to derive rfc4106 subkey

2016-07-01T15:45:06Z

Currently aesni uses an async ctr(aes) to derive the rfc4106 subkey, which was presumably copied over from the generic rfc4106 code. Over there it's done that way because we already have a ctr(aes) spawn. But it is simply overkill for aesni since we have to go get a ctr(aes) from scratch anyway. This patch simplifies the subkey derivation by using a straight aes cipher instead. Signed-off-by: Herbert Xu

crypto: sha512-mb - Crypto computation (x4 AVX2)

2016-06-28T08:06:40Z

This patch introduces the assembly routines to do SHA512 computation on buffers belonging to several jobs at once. The assembly routines are optimized with AVX2 instructions that have 4 data lanes and using AVX2 registers.

crypto: sha512-mb - Algorithm data structures

2016-06-28T08:06:39Z

This patch introduces the data structures and prototypes of functions needed for computing SHA512 hash using multi-buffer. Included are the structures of the multi-buffer SHA512 job, job scheduler in C and x86 assembly. Signed-off-by: Megha Dey Reviewed-by: Fenghua Yu Reviewed-by: Tim Chen Signed-off-by: Herbert Xu

crypto: sha512-mb - submit/flush routines for AVX2

2016-06-28T08:06:38Z

This patch introduces the routines used to submit and flush buffers belonging to SHA512 crypto jobs to the SHA512 multibuffer algorithm. It is implemented mostly in assembly optimized with AVX2 instructions. Signed-off-by: Megha Dey Reviewed-by: Fenghua Yu Reviewed-by: Tim Chen Signed-off-by: Herbert Xu

crypto: sha512-mb - SHA512 multibuffer job manager and glue code

2016-06-28T08:06:35Z

This patch introduces the multi-buffer job manager which is responsible for submitting scatter-gather buffers from several SHA512 jobs to the multi-buffer algorithm. It also contains the flush routine that's called by the crypto daemon to complete the job when no new jobs arrive before the deadline of maximum latency of a SHA512 crypto job. The SHA512 multi-buffer crypto algorithm is defined and initialized in this patch. Signed-off-by: Megha Dey Reviewed-by: Fenghua Yu Reviewed-by: Tim Chen Signed-off-by: Herbert Xu

crypto: sha1-mb - rename sha-mb to sha1-mb

2016-06-27T08:57:47Z

Until now, there was only support for the SHA1 multibuffer algorithm. Hence, there was just one sha-mb folder. Now, with the introduction of the SHA256 multi-buffer algorithm , it is logical to name the existing folder as sha1-mb.
