* crypto: ghash - Add PCLMULQDQ accelerated implementationHuang Ying2009-10-191-0/+8
| | | | | | | | | | | | | | | | PCLMULQDQ is used to accelerate the most time-consuming part of GHASH, carry-less multiplication. More information about PCLMULQDQ can be found at: http://software.intel.com/en-us/articles/carry-less-multiplication-and-its-usage-for-computing-the-gcm-mode/ Because PCLMULQDQ changes XMM state, its usage must be enclosed with kernel_fpu_begin/end, which can be used only in process context, the acceleration is implemented as crypto_ahash. That is, request in soft IRQ context will be defered to the cryptd kernel thread. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: fips - Depend on ansi_cprngNeil Horman2009-08-201-2/+6
| | | | | | | | | | | | 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.

| | | | | | | | | | This reverts commit 215ccd6f55a2144bd553e0a3d12e1386f02309fd. It causes CPRNG and everything selected by it to be built-in whenever FIPS is enabled. The problem is that it is selecting a tristate from a bool, which is usually not what is intended. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | Remove the dedicated GHASH implementation in GCM, and uses the GHASH digest algorithm instead.

* crypto: aes-ni - Add support for more modesHuang Ying2009-06-021-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Because kernel_fpu_begin() and kernel_fpu_end() operations are too slow, the performance gain of general mode implementation + aes-aesni is almost all compensated. The AES-NI support for more modes are implemented as follow: - Add a new AES algorithm implementation named __aes-aesni without kernel_fpu_begin/end() - Use fpu(<mode>(AES)) to provide kenrel_fpu_begin/end() invoking - Add <mode>(AES) ablkcipher, which uses cryptd(fpu(<mode>(AES))) to defer cryption to cryptd context in soft_irq context. Now the ctr, lrw, pcbc and xts support are added. Performance testing based on dm-crypt shows that cryption time can be reduced to 50% of general mode implementation + aes-aesni implementation.

* crypto: fpu - Add template for blkcipher touching FPUHuang Ying2009-06-021-0/+5
| | | | | | | | | | | | Blkcipher touching FPU need to be enclosed by kernel_fpu_begin() and kernel_fpu_end(). If they are invoked in cipher algorithm implementation, they will be invoked for each block, so that performance will be hurt, because they are "slow" operations. This patch implements "fpu" template, which makes these operations to be invoked for each request.

* crypto: compress - Add pcomp interfaceGeert Uytterhoeven2009-03-041-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current "comp" crypto interface supports one-shot (de)compression only, i.e. the whole data buffer to be (de)compressed must be passed at once, and the whole (de)compressed data buffer will be received at once. In several use-cases (e.g. compressed file systems that store files in big compressed blocks), this workflow is not suitable. Furthermore, the "comp" type doesn't provide for the configuration of (de)compression parameters, and always allocates workspace memory for both compression and decompression, which may waste memory. To solve this, add a "pcomp" partial (de)compression interface that provides the following operations: - crypto_compress_{init,update,final}() for compression, - crypto_decompress_{init,update,final}() for decompression, - crypto_{,de}compress_setup(), to configure (de)compression parameters (incl. allocating workspace memory). The (de)compression methods take a struct comp_request, which was mimicked after the z_stream object in zlib, and contains buffer pointer and length pairs for input and output. The setup methods take an opaque parameter pointer and length pair. Parameters are supposed to be encoded using netlink attributes, whose meanings depend on the actual (name of the) (de)compression algorithm.

In struct cryptd_cpu_queue, a struct crypto_queue holds all requests for the CPU, a struct work_struct is used to run all requests for the CPU. Testing based on dm-crypt on an Intel Core 2 E6400 (two cores) machine shows 19.2% performance gain. The testing script is as follow: -------------------- script begin --------------------------- #!/bin/sh dmc_create() { # Create a crypt device using dmsetup dmsetup create $2 --table "0 `blockdev --getsize $1` crypt cbc(aes-asm)?cryptd?plain:plain babebabebabebabebabebabebabebabe 0 $1 0" } dmsetup remove crypt0 dmsetup remove crypt1 dd if=/dev/zero of=/dev/ram0 bs=1M count=4 >& /dev/null dd if=/dev/zero of=/dev/ram1 bs=1M count=4 >& /dev/null dmc_create /dev/ram0 crypt0 dmc_create /dev/ram1 crypt1 cat >tr.sh <<EOF #!/bin/sh for n in \$(seq 10); do dd if=/dev/dm-0 of=/dev/null >& /dev/null & dd if=/dev/dm-1 of=/dev/null >& /dev/null & done wait EOF for n in $(seq 10); do /usr/bin/time sh tr.sh done rm tr.sh -------------------- script end --------------------------- The separator of dm-crypt parameter is changed from "-" to "?", because "-" is used in some cipher driver name too, and cryptds need to specify cipher driver name instead of cipher name.

* crypto: aes-ni - Add support to Intel AES-NI instructions for x86_64 platformHuang Ying2009-02-181-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | Intel AES-NI is a new set of Single Instruction Multiple Data (SIMD) instructions that are going to be introduced in the next generation of Intel processor, as of 2009. These instructions enable fast and secure data encryption and decryption, using the Advanced Encryption Standard (AES), defined by FIPS Publication number 197. The architecture introduces six instructions that offer full hardware support for AES. Four of them support high performance data encryption and decryption, and the other two instructions support the AES key expansion procedure. The white paper can be downloaded from: http://softwarecommunity.intel.com/isn/downloads/intelavx/AES-Instructions-Set_WP.pdf AES may be used in soft_irq context, but MMX/SSE context can not be touched safely in soft_irq context. So in_interrupt() is checked, if in IRQ or soft_irq context, the general x86_64 implementation are used instead.
