2010-09-20crypto: cryptd - Adding the AEAD interface type support to cryptdAdrian Hoban1-0/+24
This patch adds AEAD support into the cryptd framework. Having AEAD support in cryptd enables crypto drivers that use the AEAD interface type (such as the patch for AEAD based RFC4106 AES-GCM implementation using Intel New Instructions) to leverage cryptd for asynchronous processing.

2009-10-19crypto: ghash - Add PCLMULQDQ accelerated implementationHuang Ying1-0/+1
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>
2009-08-06crypto: cryptd - Add support to access underlaying shashHuang Ying1-0/+17
cryptd_alloc_ahash() will allocate a cryptd-ed ahash for specified algorithm name. The new allocated one is guaranteed to be cryptd-ed ahash, so the shash underlying can be gotten via cryptd_ahash_child().

2009-02-18crypto: cryptd - Add support to access underlying blkcipherHuang Ying1-0/+27
cryptd_alloc_ablkcipher() will allocate a cryptd-ed ablkcipher for specified algorithm name. The new allocated one is guaranteed to be cryptd-ed ablkcipher, so the blkcipher underlying can be gotten via cryptd_ablkcipher_child().
