* crypto: twofish - add AVX2/x86_64 assembler implementation of twofish cipherJussi Kivilinna2013-04-252-0/+36
| | | | | | | | | | | 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.

* crypto: aesni_intel - add more optimized XTS mode for x86-64Jussi Kivilinna2013-04-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three errors resulting in kernel memory disclosure: 1/ The structures used for the netlink based crypto algorithm report API are located on the stack. As snprintf() does not fill the remainder of the buffer with null bytes, those stack bytes will be disclosed to users of the API. Switch to strncpy() to fix this. 2/ crypto_report_one() does not initialize all field of struct crypto_user_alg. Fix this to fix the heap info leak. 3/ For the module name we should copy only as many bytes as module_name() returns -- not as much as the destination buffer could hold. But the current code does not and therefore copies random data from behind the end of the module name, as the module name is always shorter than CRYPTO_MAX_ALG_NAME. Also switch to use strncpy() to copy the algorithm's name and driver_name. They are strings, after all.

Implementation process data in sixteen block chunks, which are byte-sliced and AES SubBytes is reused for Camellia s-box with help of pre- and post-filtering.

| * crypto: crc32c - Optimize CRC32C calculation with PCLMULQDQ instructionTim Chen2012-10-151-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the crc_pcl function that calculates CRC32C checksum using the PCLMULQDQ instruction on processors that support this feature. This will provide speedup over using CRC32 instruction only. The usage of PCLMULQDQ necessitate the invocation of kernel_fpu_begin and kernel_fpu_end and incur some overhead. So the new crc_pcl function is only invoked for buffer size of 512 bytes or more. Larger sized buffers will expect to see greater speedup. This feature is best used coupled with eager_fpu which reduces the kernel_fpu_begin/end overhead. For buffer size of 1K the speedup is around 1.6x and for buffer size greater than 4K, the speedup is around 3x compared to original implementation in crc32c-intel module. Test was performed on Sandy Bridge based platform with constant frequency set for cpu.
