crypto: api - Remove unused crypto_type lookup function

2018-03-30T17:32:57+00:00

The lookup function in crypto_type was only used for the implicit
IV generators which have been completely removed from the crypto
API.

This patch removes the lookup function as it is now useless.

crypto: hash - Prevent use of req->result in ahash update

2018-03-16T15:35:52+00:00

Prevent improper use of req->result field in ahash update, init, export and
import functions in drivers code. A driver should use ahash request context
if it needs to save internal state.

crypto: sm4 - introduce SM4 symmetric cipher algorithm

2018-03-16T15:35:48+00:00

Introduce the SM4 cipher algorithms (OSCCA GB/T 32907-2016).

SM4 (GBT.32907-2016) is a cryptographic standard issued by the
Organization of State Commercial Administration of China (OSCCA)
as an authorized cryptographic algorithms for the use within China.

SMS4 was originally created for use in protecting wireless
networks, and is mandated in the Chinese National Standard for
Wireless LAN WAPI (Wired Authentication and Privacy Infrastructure)
(GB.15629.11-2003).

crypto: ablk_helper - remove ablk_helper

2018-03-02T16:03:38+00:00

All users of ablk_helper have been converted over to crypto_simd, so
remove ablk_helper.

crypto: lrw - remove lrw_crypt()

2018-03-02T16:03:34+00:00

Now that all users of lrw_crypt() have been removed in favor of the LRW
template wrapping an ECB mode algorithm, remove lrw_crypt().  Also
remove crypto/lrw.h as that is no longer needed either; and fold
'struct lrw_table_ctx' into 'struct priv', lrw_init_table() into
setkey(), and lrw_free_table() into exit_tfm().

2018-03-02T16:03:33+00:00

Now that all users of xts_crypt() have been removed in favor of the XTS
template wrapping an ECB mode algorithm, remove xts_crypt().

crypto: simd - allow registering multiple algorithms at once

2018-03-02T16:03:17+00:00

Add a function to crypto_simd that registers an array of skcipher
algorithms, then allocates and registers the simd wrapper algorithms for
them.  It assumes the naming scheme where the names of the underlying
algorithms are prefixed with two underscores.

Also add the corresponding 'unregister' function.

Most of the x86 crypto modules will be able to use these.

crypto: speck - export common helpers

2018-02-22T14:16:54+00:00

Export the Speck constants and transform context and the ->setkey(),
->encrypt(), and ->decrypt() functions so that they can be reused by the
ARM NEON implementation of Speck-XTS.  The generic key expansion code
will be reused because it is not performance-critical and is not
vectorizable, while the generic encryption and decryption functions are
needed as fallbacks and for the XTS tweak encryption.

crypto: engine - Permit to enqueue all async requests

2018-02-15T15:26:50+00:00

The crypto engine could actually only enqueue hash and ablkcipher request.
This patch permit it to enqueue any type of crypto_async_request.

crypto: mcryptd - remove pointless wrapper functions

2018-02-15T15:26:45+00:00

There is no need for ahash_mcryptd_{update,final,finup,digest}(); we
should just call crypto_ahash_*() directly.
