2012-03-14crypto: camellia - add assembler implementation for x86_64Jussi Kivilinna1-0/+18
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.

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.

2011-05-16crypto: aesni-intel - Merge with fpu.koAndy Lutomirski1-6/+0
Loading fpu without aesni-intel does nothing. Loading aesni-intel without fpu causes modes like xts to fail. (Unloading aesni-intel will restore those modes.) One solution would be to make aesni-intel depend on fpu, but it seems cleaner to just combine the modules.

2010-11-27crypto: aesni-intel - Ported implementation to x86-32Mathias Krause1-5/+7
The AES-NI instructions are also available in legacy mode so the 32-bit architecture may profit from those, too. To illustrate the performance gain here's a short summary of a dm-crypt speed test on a Core i7 M620 running at 2.67GHz comparing both assembler implementations: x86: i568 aes-ni delta ECB, 256 bit: 93.8 MB/s 123.3 MB/s +31.4% CBC, 256 bit: 84.8 MB/s 262.3 MB/s +209.3% LRW, 256 bit: 108.6 MB/s 222.1 MB/s +104.5% XTS, 256 bit: 105.0 MB/s 205.5 MB/s +95.7% Additionally, due to some minor optimizations, the 64-bit version also got a minor performance gain as seen below: x86-64: old impl. new impl. delta ECB, 256 bit: 121.1 MB/s 123.0 MB/s +1.5% CBC, 256 bit: 285.3 MB/s 290.8 MB/s +1.9% LRW, 256 bit: 263.7 MB/s 265.3 MB/s +0.6% XTS, 256 bit: 251.1 MB/s 255.3 MB/s +1.7% Signed-off-by: Mathias Krause <minipli@googlemail.com> Reviewed-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2010-11-26crypto: algif_skcipher - User-space interface for skcipher operationsHerbert Xu1-0/+8
This patch adds the af_alg plugin for symmetric key ciphers, corresponding to the ablkcipher kernel operation type. Keys can optionally be set through the setsockopt interface. Once a sendmsg call occurs without MSG_MORE no further writes may be made to the socket until all previous data has been read. IVs and and whether encryption/decryption is performed can be set through the setsockopt interface or as a control message to sendmsg. The interface is completely synchronous, all operations are carried out in recvmsg(2) and will complete prior to the system call returning. The splice(2) interface support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). The recvmsg(2) interface supports directly writing to user-space without additional copying, i.e., the kernel crypto interface will receive the user-space address as its output SG list.

2010-11-19crypto: algif_hash - User-space interface for hash operationsHerbert Xu1-0/+8
This patch adds the af_alg plugin for hash, corresponding to the ahash kernel operation type. Keys can optionally be set through the setsockopt interface. Each sendmsg call will finalise the hash unless sent with a MSG_MORE flag. Partial hash states can be cloned using accept(2). The interface is completely synchronous, all operations will complete prior to the system call returning. Both sendmsg(2) and splice(2) support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). For now only the splice(2) interface supports performing digest instead of init/update/final. In future the sendmsg(2) interface will also be modified to use digest/finup where possible so that hardware that cannot return a partial hash state can still benefit from this interface.

2010-11-19crypto: af_alg - User-space interface for Crypto APIHerbert Xu1-0/+3
This patch creates the backbone of the user-space interface for the Crypto API, through a new socket family AF_ALG. Each session corresponds to one or more connections obtained from that socket. The number depends on the number of inputs/outputs of that particular type of operation. For most types there will be a s ingle connection/file descriptor that is used for both input and output. AEAD is one of the few that require two inputs. Each algorithm type will provide its own implementation that plugs into af_alg. They're keyed using a string such as "skcipher" or "hash". IOW this patch only contains the boring bits that is required to hold everything together. Thakns to Miloslav Trmac for reviewing this and contributing fixes and improvements.

What about something like this? It defaults the CPRNG to m and makes FIPS dependent on the CPRNG. That way you get a module build by default, but you can change it to y manually during config and still satisfy the dependency, and if you select N it disables FIPS as well. I rather like that better than making FIPS a tristate. I just tested it out here and it seems to work well.
