crypto: skcipher - introduce walksize attribute for SIMD algos

2016-12-30T11:52:47+00:00

In some cases, SIMD algorithms can only perform optimally when
allowed to operate on multiple input blocks in parallel. This is
especially true for bit slicing algorithms, which typically take
the same amount of time processing a single block or 8 blocks in
parallel. However, other SIMD algorithms may benefit as well from
bigger strides.

So add a walksize attribute to the skcipher algorithm definition, and
wire it up to the skcipher walk API. To avoid confusion between the
skcipher and AEAD attributes, rename the skcipher_walk chunksize
attribute to 'stride', and set it from the walksize (in the skcipher
case) or from the chunksize (in the AEAD case).

crypto: skcipher - Add separate walker for AEAD decryption

2016-12-01T13:06:17+00:00

The AEAD decrypt interface includes the authentication tag in
req->cryptlen.  Therefore we need to exlucde that when doing
a walk over it.

This patch adds separate walker functions for AEAD encryption
and decryption.

crypto: simd - Add simd skcipher helper

2016-11-28T13:23:18+00:00

This patch adds the simd skcipher helper which is meant to be
a replacement for ablk helper.  It replaces the underlying blkcipher
interface with skcipher, and also presents the top-level algorithm
as an skcipher.

crypto: skcipher - Add skcipher walk interface

2016-11-28T13:23:17+00:00

This patch adds the skcipher walk interface which replaces both
blkcipher walk and ablkcipher walk.  Just like blkcipher walk it
can also be used for AEAD algorithms.

crypto: skcipher - Get rid of crypto_spawn_skcipher2()

2016-11-01T00:37:17+00:00

Since commit 3a01d0ee2b99 ("crypto: skcipher - Remove top-level
givcipher interface"), crypto_spawn_skcipher2() and
crypto_spawn_skcipher() are equivalent.  So switch callers of
crypto_spawn_skcipher2() to crypto_spawn_skcipher() and remove it.

crypto: acomp - add driver-side scomp interface

2016-10-25T03:08:31+00:00

Add a synchronous back-end (scomp) to acomp. This allows to easily
expose the already present compression algorithms in LKCF via acomp.

crypto: skcipher - Remove unused crypto_lookup_skcipher() declaration

2016-10-21T03:03:41+00:00

The definition of crypto_lookup_skcipher() was already removed in
commit 3a01d0ee2b99 ("crypto: skcipher - Remove top-level givcipher
interface").  So the declaration should be removed too.

crypto: skcipher - Remove top-level givcipher interface

2016-07-18T09:35:46+00:00

This patch removes the old crypto_grab_skcipher helper and replaces
it with crypto_grab_skcipher2.

As this is the final entry point into givcipher this patch also
removes all traces of the top-level givcipher interface, including
all implicit IV generators such as chainiv.

The bottom-level givcipher interface remains until the drivers
using it are converted.
