crypto: camellia - add assembler implementation for x86_64 Patch adds x86_64 assembler implementation of Camellia block cipher. Two set of functions are provided. First set is regular 'one-block at time' encrypt/decrypt functions. Second is 'two-block at time' functions that gain performance increase on out-of-order CPUs. Performance of 2-way functions should be equal to 1-way functions with in-order CPUs. Patch has been tested with tcrypt and automated filesystem tests.

crypto: sha1 - SSSE3 based SHA1 implementation for x86-64 This is an assembler implementation of the SHA1 algorithm using the Supplemental SSE3 (SSSE3) instructions or, when available, the Advanced Vector Extensions (AVX). Testing with the tcrypt module shows the raw hash performance is up to 2.3 times faster than the C implementation, using 8k data blocks on a Core 2 Duo T5500. For the smalest data set (16 byte) it is still 25% faster. Since this implementation uses SSE/YMM registers it cannot safely be used in every situation, e.g. while an IRQ interrupts a kernel thread. The implementation falls back to the generic SHA1 variant, if using the SSE/YMM registers is not possible. With this algorithm I was able to increase the throughput of a single IPsec link from 344 Mbit/s to 464 Mbit/s on a Core 2 Quad CPU using the SSSE3 variant -- a speedup of +34.8%. Saving and restoring SSE/YMM state might make the actual throughput fluctuate when there are FPU intensive userland applications running. For example, meassuring the performance using iperf2 directly on the machine under test gives wobbling numbers because iperf2 uses the FPU for each packet to check if the reporting interval has expired (in the above test I got min/max/avg: 402/484/464 MBit/s). Using this algorithm on a IPsec gateway gives much more reasonable and stable numbers, albeit not as high as in the directly connected case. Here is the result from an RFC 2544 test run with a EXFO Packet Blazer FTB-8510: frame size sha1-generic sha1-ssse3 delta 64 byte 37.5 MBit/s 37.5 MBit/s 0.0% 128 byte 56.3 MBit/s 62.5 MBit/s +11.0% 256 byte 87.5 MBit/s 100.0 MBit/s +14.3% 512 byte 131.3 MBit/s 150.0 MBit/s +14.2% 1024 byte 162.5 MBit/s 193.8 MBit/s +19.3% 1280 byte 175.0 MBit/s 212.5 MBit/s +21.4% 1420 byte 175.0 MBit/s 218.7 MBit/s +25.0% 1518 byte 150.0 MBit/s 181.2 MBit/s +20.8% The throughput for the largest frame size is lower than for the previous size because the IP packets need to be fragmented in this case to make there way through the IPsec tunnel.

crypto: serpent - add 8-way parallel x86_64/SSE2 assembler implementation Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations in parallel to improve performance on out-of-order CPUs). Glue code is based on one from AES-NI implementation, so requests from irq context are redirected to cryptd. v2: - add missing include of linux/module.h (appearently crypto.h used to include module.h, which changed for 3.2 by commit 7c926402a7e8c9b279968fd94efec8700ba3859e) Patch has been tested with tcrypt and automated filesystem tests.

crypto: aes - AES CTR x86_64 "by8" AVX optimization This patch introduces "by8" AES CTR mode AVX optimization inspired by Intel Optimized IPSEC Cryptograhpic library. For additional information, please see: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22972 The functions aes_ctr_enc_128_avx_by8(), aes_ctr_enc_192_avx_by8() and aes_ctr_enc_256_avx_by8() are adapted from Intel Optimized IPSEC Cryptographic library. When both AES and AVX features are enabled in a platform, the glue code in AESNI module overrieds the existing "by4" CTR mode en/decryption with the "by8" AES CTR mode en/decryption. On a Haswell desktop, with turbo disabled and all cpus running at maximum frequency, the "by8" CTR mode optimization shows better performance results across data & key sizes as measured by tcrypt. The average performance improvement of the "by8" version over the "by4" version is as follows: For 128 bit key and data sizes >= 256 bytes, there is a 10-16% improvement. For 192 bit key and data sizes >= 256 bytes, there is a 20-22% improvement. For 256 bit key and data sizes >= 256 bytes, there is a 20-25% improvement. A typical run of tcrypt with AES CTR mode encryption of the "by4" and "by8" optimization shows the following results: tcrypt with "by4" AES CTR mode encryption optimization on a Haswell Desktop:

crypto: sha1 - SSSE3 based SHA1 implementation for x86-64 This is an assembler implementation of the SHA1 algorithm using the Supplemental SSE3 (SSSE3) instructions or, when available, the Advanced Vector Extensions (AVX). Testing with the tcrypt module shows the raw hash performance is up to 2.3 times faster than the C implementation, using 8k data blocks on a Core 2 Duo T5500. For the smalest data set (16 byte) it is still 25% faster. Since this implementation uses SSE/YMM registers it cannot safely be used in every situation, e.g. while an IRQ interrupts a kernel thread. The implementation falls back to the generic SHA1 variant, if using the SSE/YMM registers is not possible. With this algorithm I was able to increase the throughput of a single IPsec link from 344 Mbit/s to 464 Mbit/s on a Core 2 Quad CPU using the SSSE3 variant -- a speedup of +34.8%. Saving and restoring SSE/YMM state might make the actual throughput fluctuate when there are FPU intensive userland applications running. For example, meassuring the performance using iperf2 directly on the machine under test gives wobbling numbers because iperf2 uses the FPU for each packet to check if the reporting interval has expired (in the above test I got min/max/avg: 402/484/464 MBit/s). Using this algorithm on a IPsec gateway gives much more reasonable and stable numbers, albeit not as high as in the directly connected case. Here is the result from an RFC 2544 test run with a EXFO Packet Blazer FTB-8510: frame size sha1-generic sha1-ssse3 delta 64 byte 37.5 MBit/s 37.5 MBit/s 0.0% 128 byte 56.3 MBit/s 62.5 MBit/s +11.0% 256 byte 87.5 MBit/s 100.0 MBit/s +14.3% 512 byte 131.3 MBit/s 150.0 MBit/s +14.2% 1024 byte 162.5 MBit/s 193.8 MBit/s +19.3% 1280 byte 175.0 MBit/s 212.5 MBit/s +21.4% 1420 byte 175.0 MBit/s 218.7 MBit/s +25.0% 1518 byte 150.0 MBit/s 181.2 MBit/s +20.8% The throughput for the largest frame size is lower than for the previous size because the IP packets need to be fragmented in this case to make there way through the IPsec tunnel.
