crypto: marvell/cesa - rename blkcipher to skcipher

2019-11-17T01:02:49+00:00

The driver specific types contain some rudimentary references to the
blkcipher API, which is deprecated and will be removed. To avoid confusion,
rename these to skcipher. This is a cosmetic change only, as the code does
not actually use the blkcipher API.

crypto: cesa/aes - switch to library version of key expansion routine

2019-07-26T04:56:03+00:00

Switch to the new AES library that also provides an implementation of
the AES key expansion routine. This removes the dependency on the
generic AES cipher, allowing it to be omitted entirely in the future.

crypto: clarify name of WEAK_KEY request flag

2019-01-25T10:41:52+00:00

CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it
sounds like it is requesting a weak key.  Actually, it is requesting
that weak keys be forbidden (for algorithms that have the notion of
"weak keys"; currently only DES and XTS do).

Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which
it can be easily confused.  (This in fact happened in the UX500 driver,
though just in some debugging messages.)

Therefore, make the intent clear by renaming it to
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS.

crypto: marvell - Switch cipher algs to the skcipher interface

2017-11-03T13:53:32+00:00

crypto_alg is not supposed to be directly implemented by crypto engine
driver. Drivers should instead implement specialized interfaces like
ahash_alg or skcipher_alg.

Migrate to all cipher algorithms to the skcipher_alg interface. While at
it, get rid of all references to ablkcipher including in internal struct
or function names.

crypto: marvell - Use an unique pool to copy results of requests

2016-10-21T03:03:40+00:00

So far, we used a dedicated dma pool to copy the result of outer IV for
cipher requests. Instead of using a dma pool per outer data, we prefer
use the op dma pool that contains all part of the request from the SRAM.
Then, the outer data that is likely to be used by the 'complete'
operation, is copied later. In this way, any type of result can be
retrieved by DMA for cipher or ahash requests.

crypto: marvell - Don't copy IV vectors from the _process op for ciphers

2016-07-29T10:30:17+00:00

The IV output vectors should only be copied from the _complete operation
and not from the _process operation, i.e only from the operation that is
designed to copy the result of the request to the right location. This
copy is already done in the _complete operation, so this commit removes
the duplicated code in the _process op.
