crypto: sha1-mb - async implementation for sha1-mb

2016-06-23T10:29:55Z

Herbert wants the sha1-mb algorithm to have an async implementation: https://lkml.org/lkml/2016/4/5/286. Currently, sha1-mb uses an async interface for the outer algorithm and a sync interface for the inner algorithm. This patch introduces a async interface for even the inner algorithm.

crypto: hash - Remove crypto_hash interface

2016-02-06T07:33:20Z

This patch removes all traces of the crypto_hash interface, now that everyone has switched over to shash or ahash. Signed-off-by: Herbert Xu

crypto: sha-mb - multibuffer crypto infrastructure

2014-08-25T12:32:25Z

This patch introduces the multi-buffer crypto daemon which is responsible for submitting crypto jobs in a work queue to the responsible multi-buffer crypto algorithm. The idea of the multi-buffer algorihtm is to put data streams from multiple jobs in a wide (AVX2) register and then take advantage of SIMD instructions to do crypto computation on several buffers simultaneously. The multi-buffer crypto daemon is also responsbile for flushing the remaining buffers to complete the computation if no new buffers arrive for a while.

crypto: hash - Add real ahash walk interface

2014-05-21T12:56:12Z

Although the existing hash walk interface has already been used by a number of ahash crypto drivers, it turns out that none of them were really asynchronous. They were all essentially polling for completion. That's why nobody has noticed until now that the walk interface couldn't work with a real asynchronous driver since the memory is mapped using kmap_atomic. As we now have a use-case for a real ahash implementation on x86, this patch creates a minimal ahash walk interface. Basically it just calls kmap instead of kmap_atomic and does away with the crypto_yield call. Real ahash crypto drivers don't need to yield since by definition they won't be hogging the CPU.

crypto: add crypto_[un]register_shashes for [un]registering multiple shash entries at once

2012-08-01T09:47:26Z

Add crypto_[un]register_shashes() to allow simplifying init/exit code of shash crypto modules that register multiple algorithms. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: ahash - Add unaligned handling and default operations

2009-07-15T04:40:40Z

This patch exports the finup operation where available and adds a default finup operation for ahash. The operations final, finup and digest also will now deal with unaligned result pointers by copying it. Finally export/import operations are will now be exported too. Signed-off-by: Herbert Xu

crypto: ahash - Remove old_ahash_alg

2009-07-14T12:29:57Z

Now that all ahash implementations have been converted to the new ahash type, we can remove old_ahash_alg and its associated support. Signed-off-by: Herbert Xu

crypto: crypto4xx - Switch to new style ahash

2009-07-14T12:21:46Z

This patch changes crypto4xx to use the new style ahash type. In particular, we now use ahash_alg to define ahash algorithms instead of crypto_alg. This is achieved by introducing a union that encapsulates the new type and the existing crypto_alg structure. They're told apart through a u32 field containing the type value.

crypto: hash - Add helpers to free spawns

2009-07-14T10:30:24Z

This patch adds the helpers crypto_drop_ahash and crypto_drop_shash so that these spawns can be dropped without ugly casts. Signed-off-by: Herbert Xu

crypto: ahash - Add instance/spawn support

2009-07-14T07:54:09Z

This patch adds support for creating ahash instances and using ahash as spawns. Signed-off-by: Herbert Xu
