2011-10-21crypto: blowfish-x86_64 - improve x86_64 blowfish 4-way performanceJussi Kivilinna1-100/+98
This patch adds improved F-macro for 4-way parallel functions. With new F-macro for 4-way parallel functions, blowfish sees ~15% improvement in speed tests on AMD Phenom II (~5% on Intel Xeon E7330). However when used in 1-way blowfish function new macro would be ~10% slower than original, so old F-macro is kept for 1-way functions. Patch cleans up old F-macro as it is no longer needed in 4-way part. Patch also does register macro renaming to reduce stack usage.

2011-08-10crypto: sha1 - SSSE3 based SHA1 implementation for x86-64Mathias Krause5-0/+819
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.

2011-08-10crypto: sha1 - export sha1_update for reuseMathias Krause2-4/+8
Export the update function as crypto_sha1_update() to not have the need to reimplement the same algorithm for each SHA-1 implementation. This way the generic SHA-1 implementation can be used as fallback for other implementations that fail to run under certain circumstances, like the need for an FPU context while executing in IRQ context.

2011-08-03crypto: padlock-aes - Make module loading even quieter when hardware is missingJonathan Nieder1-3/+1
When loading aes via the module alias, a padlock module failing to load due to missing hardware is not particularly notable. With v2.6.27-rc1~1107^2~14 (crypto: padlock - Make module loading quieter when hardware isn't available, 2008-07-03), the padlock-aes module suppresses the relevant messages when the "quiet" flag is in use; but better to suppress this particular message completely, since the administrator can already distinguish such errors by the absence of a message indicating initialization failing or succeeding. This avoids occasional messages in syslog of the form padlock_aes: VIA PadLock not detected.

2011-08-02oom: task->mm == NULL doesn't mean the memory was freedOleg Nesterov1-1/+3
exit_mm() sets ->mm == NULL then it does mmput()->exit_mmap() which frees the memory. However select_bad_process() checks ->mm != NULL before TIF_MEMDIE, so it continues to kill other tasks even if we have the oom-killed task freeing its memory. Change select_bad_process() to check ->mm after TIF_MEMDIE, but skip the tasks which have already passed exit_notify() to ensure a zombie with TIF_MEMDIE set can't block oom-killer. Alternatively we could probably clear TIF_MEMDIE after exit_mmap().

2011-08-02ext4: prevent memory leaks from ext4_mb_init_backend() on error pathYu Jian1-6/+6
In ext4_mb_init(), if the s_locality_group allocation fails it will currently cause the allocations made in ext4_mb_init_backend() to be leaked. Moving the ext4_mb_init_backend() allocation after the s_locality_group allocation avoids that problem.
