The tsgl scatterlist must be re-initialized after each operation. Otherwise the sticky bits in the page_link will corrupt the list with pre-mature termination or false chaining. Signed-off-by: Lars Persson <larper@axis.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-21crypto: testmgr - Use new skcipher interfaceHerbert Xu
This patch replaces uses of blkcipher and ablkcipher with the new skcipher interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-08-21crypto: skcipher - Add top-level skcipher interfaceHerbert Xu
This patch introduces the crypto skcipher interface which aims to replace both blkcipher and ablkcipher. It's very similar to the existing ablkcipher interface. The main difference is the removal of the givcrypt interface. In order to make the transition easier for blkcipher users, there is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place a request on the stack for synchronous transforms.

2015-07-17crypto: poly1305 - Add a SSE2 SIMD variant for x86_64Martin Willi
Implements an x86_64 assembler driver for the Poly1305 authenticator. This single block variant holds the 130-bit integer in 5 32-bit words, but uses SSE to do two multiplications/additions in parallel. When calling updates with small blocks, the overhead for kernel_fpu_begin/ kernel_fpu_end() negates the perfmance gain. We therefore use the poly1305-generic fallback for small updates. For large messages, throughput increases by ~5-10% compared to poly1305-generic: testing speed of poly1305 (poly1305-generic) test 0 ( 96 byte blocks, 16 bytes per update, 6 updates): 4080026 opers/sec, 391682496 bytes/sec test 1 ( 96 byte blocks, 32 bytes per update, 3 updates): 6221094 opers/sec, 597225024 bytes/sec test 2 ( 96 byte blocks, 96 bytes per update, 1 updates): 9609750 opers/sec, 922536057 bytes/sec test 3 ( 288 byte blocks, 16 bytes per update, 18 updates): 1459379 opers/sec, 420301267 bytes/sec test 4 ( 288 byte blocks, 32 bytes per update, 9 updates): 2115179 opers/sec, 609171609 bytes/sec test 5 ( 288 byte blocks, 288 bytes per update, 1 updates): 3729874 opers/sec, 1074203856 bytes/sec test 6 ( 1056 byte blocks, 32 bytes per update, 33 updates): 593000 opers/sec, 626208000 bytes/sec test 7 ( 1056 byte blocks, 1056 bytes per update, 1 updates): 1081536 opers/sec, 1142102332 bytes/sec test 8 ( 2080 byte blocks, 32 bytes per update, 65 updates): 302077 opers/sec, 628320576 bytes/sec test 9 ( 2080 byte blocks, 2080 bytes per update, 1 updates): 554384 opers/sec, 1153120176 bytes/sec test 10 ( 4128 byte blocks, 4128 bytes per update, 1 updates): 278715 opers/sec, 1150536345 bytes/sec test 11 ( 8224 byte blocks, 8224 bytes per update, 1 updates): 140202 opers/sec, 1153022070 bytes/sec testing speed of poly1305 (poly1305-simd) test 0 ( 96 byte blocks, 16 bytes per update, 6 updates): 3790063 opers/sec, 363846076 bytes/sec test 1 ( 96 byte blocks, 32 bytes per update, 3 updates): 5913378 opers/sec, 567684355 bytes/sec test 2 ( 96 byte blocks, 96 bytes per update, 1 updates): 9352574 opers/sec, 897847104 bytes/sec test 3 ( 288 byte blocks, 16 bytes per update, 18 updates): 1362145 opers/sec, 392297990 bytes/sec test 4 ( 288 byte blocks, 32 bytes per update, 9 updates): 2007075 opers/sec, 578037628 bytes/sec test 5 ( 288 byte blocks, 288 bytes per update, 1 updates): 3709811 opers/sec, 1068425798 bytes/sec test 6 ( 1056 byte blocks, 32 bytes per update, 33 updates): 566272 opers/sec, 597984182 bytes/sec test 7 ( 1056 byte blocks, 1056 bytes per update, 1 updates): 1111657 opers/sec, 1173910108 bytes/sec test 8 ( 2080 byte blocks, 32 bytes per update, 65 updates): 288857 opers/sec, 600823808 bytes/sec test 9 ( 2080 byte blocks, 2080 bytes per update, 1 updates): 590746 opers/sec, 1228751888 bytes/sec test 10 ( 4128 byte blocks, 4128 bytes per update, 1 updates): 301825 opers/sec, 1245936902 bytes/sec test 11 ( 8224 byte blocks, 8224 bytes per update, 1 updates): 153075 opers/sec, 1258896201 bytes/sec Benchmark results from a Core i5-4670T.

This patch disables the rfc4106 test while the conversion to the new seqiv calling convention takes place. It also converts the rfc4106 test vectors to the new format. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch allows the CRYPTO_ALG_AEAD_NEW flag to be propagated. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-07-14crypto: seqiv - Replace seqniv with seqivHerbert Xu
This patch replaces the seqniv generator with seqiv when the underlying algorithm understands the new calling convention. This not only makes more sense as now seqiv is solely responsible for IV generation rather than also determining how the IV is going to be used, it also allows for optimisations in the underlying implementation. For example, the space for the IV could be used to add padding for authentication. This patch also removes the unnecessary copying of IV to dst during seqiv decryption as the IV is part of the AD and not cipher text. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-07-14crypto: echainiv - Fix encryption conventionHerbert Xu
This patch fixes a bug where we were incorrectly including the IV in the AD during encryption. The IV must remain in the plain text for it to be encrypted. During decryption there is no need to copy the IV to dst because it's now part of the AD. This patch removes an unncessary check on authsize which would be performed by the underlying decrypt call. Finally this patch makes use of the type-safe init/exit functions. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-07-14crypto: pcrypt - Propagate new AEAD implementation flagHerbert Xu
This patch allows the CRYPTO_ALG_AEAD_NEW flag to be propagated. It also restores the ASYNC bit that went missing during the AEAD conversion. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
