Commits 2cdc6899a8 ("crypto: ghash - Add GHASH digest algorithm for GCM") and 0e1227d356 ("crypto: ghash - Add PCLMULQDQ accelerated implementation") added "select CRYPTO_SHASH" to two entries.

2011-10-21crypto: ghash - Avoid null pointer dereference if no key is setNick Bowler1-0/+6
The ghash_update function passes a pointer to gf128mul_4k_lle which will be NULL if ghash_setkey is not called or if the most recent call to ghash_setkey failed to allocate memory. This causes an oops. Fix this up by returning an error code in the null case. This is trivially triggered from unprivileged userspace through the AF_ALG interface by simply writing to the socket without setting a key. The ghash_final function has a similar issue, but triggering it requires a memory allocation failure in ghash_setkey _after_ at least one successful call to ghash_update.

2011-08-10crypto: sha1 - SSSE3 based SHA1 implementation for x86-64Mathias Krause1-0/+10
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.

2011-07-08crypto: gf128mul - fix call to memset()Mathias Krause1-2/+2
In gf128mul_lle() and gf128mul_bbe() r isn't completely initialized with zero because the size argument passed to memset() is the size of the pointer, not the structure it points to. Luckily there are no in-kernel users of those functions so the ABI change implied by this fix should break no existing code. Based on a patch by the PaX Team.

When the first call to af_alg_make_sg fails, we may return garbage instead of the real error. This patch fixes it by setting the error if "copied" is zero. Based on a patch by Jesper Juhl. Reported-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
