crypto: cryptd - Add helpers to check whether a tfm is queued 2016-06-23T10:29:52+00:00 Herbert Xu herbert@gondor.apana.org.au 2016-06-21T08:55:13+00:00 81760ea6a95ad4c41273a71052f61b9f087b5753 This patch adds helpers to check whether a given tfm is currently queued. This is meant to be used by ablk_helper and similar entities to ensure that no reordering is introduced because of requests queued in cryptd with respect to requests being processed in softirq context. The per-cpu queue length limit is also increased to 1000 in line with network limits. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: cryptd - Adding the AEAD interface type support to cryptd 2010-09-20T08:05:12+00:00 Adrian Hoban adrian.hoban@intel.com 2010-09-20T08:05:12+00:00 298c926c6d7f50d91d6acb76c33b83bab5b5bd5c 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.

crypto: ghash - Add PCLMULQDQ accelerated implementation 2009-10-19T02:53:06+00:00 Huang Ying ying.huang@intel.com 2009-10-19T02:53:06+00:00 0e1227d356e9b2fe0500d6cc7084f752040a1e0e 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>
