crypto: camellia - add AVX2/AES-NI/x86_64 assembler implementation of camellia cipher

2013-04-25T13:09:07+00:00

Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring 32 parallel blocks for input (512 bytes). Compared to AVX implementation, this version is extended to use the 256-bit wide YMM registers. For AES-NI instructions data is split to two 128-bit registers and merged afterwards. Even with this additional handling, performance should be higher compared to the AES-NI/AVX implementation. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: serpent - add AVX2/x86_64 assembler implementation of serpent cipher

2013-04-25T13:09:07+00:00

Patch adds AVX2/x86-64 implementation of Serpent cipher, requiring 16 parallel blocks for input (256 bytes). Implementation is based on the AVX implementation and extends to use the 256-bit wide YMM registers. Since serpent does not use table look-ups, this implementation should be close to two times faster than the AVX implementation. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: twofish - add AVX2/x86_64 assembler implementation of twofish cipher

2013-04-25T13:09:05+00:00

Patch adds AVX2/x86-64 implementation of Twofish cipher, requiring 16 parallel blocks for input (256 bytes). Table look-ups are performed using vpgatherdd instruction directly from vector registers and thus should be faster than earlier implementations. Implementation also uses 256-bit wide YMM registers, which should give additional speed up compared to the AVX implementation. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: blowfish - add AVX2/x86_64 implementation of blowfish cipher

2013-04-25T13:09:04+00:00

Patch adds AVX2/x86-64 implementation of Blowfish cipher, requiring 32 parallel blocks for input (256 bytes). Table look-ups are performed using vpgatherdd instruction directly from vector registers and thus should be faster than earlier implementations.

crypto: aesni_intel - fix Kconfig problem with CRYPTO_GLUE_HELPER_X86

2013-04-25T13:01:53+00:00

The Kconfig setting for glue helper module is CRYPTO_GLUE_HELPER_X86, but recent change for aesni_intel used CRYPTO_GLUE_HELPER instead. Patch corrects this issue. Cc: kbuild-all@01.org Reported-by: kbuild test robot Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: aesni_intel - add more optimized XTS mode for x86-64

2013-04-25T13:01:53+00:00

Add more optimized XTS code for aesni_intel in 64-bit mode, for smaller stack usage and boost for speed. tcrypt results, with Intel i5-2450M: 256-bit key enc dec 16B 0.98x 0.99x 64B 0.64x 0.63x 256B 1.29x 1.32x 1024B 1.54x 1.58x 8192B 1.57x 1.60x 512-bit key enc dec 16B 0.98x 0.99x 64B 0.60x 0.59x 256B 1.24x 1.25x 1024B 1.39x 1.42x 8192B 1.38x 1.42x I chose not to optimize smaller than block size of 256 bytes, since XTS is practically always used with data blocks of size 512 bytes. This is why performance is reduced in tcrypt for 64 byte long blocks. Cc: Huang Ying Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: add CMAC support to CryptoAPI

2013-04-25T13:01:47+00:00

Patch adds support for NIST recommended block cipher mode CMAC to CryptoAPI. This work is based on Tom St Denis' earlier patch, http://marc.info/?l=linux-crypto-vger&m=135877306305466&w=2 Cc: Tom St Denis Signed-off-by: Jussi Kivilinna Acked-by: David S. Miller Signed-off-by: Herbert Xu

crypto: gcm - make GMAC work when dst and src are different

2013-04-25T13:01:46+00:00

The GMAC code assumes that dst==src, which causes problems when trying to add rfc4543(gcm(aes)) test vectors. So fix this code to work when source and destination buffer are different. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu
