* crypto: ablkcipher - remove deprecated and unused ablkcipher supportArd Biesheuvel2019-11-171-19/+1
| | | | | | | | | | Now that all users of the deprecated ablkcipher interface have been moved to the skcipher interface, ablkcipher is no longer used and can be removed.

* crypto: skcipher - remove the "blkcipher" algorithm typeEric Biggers2019-11-011-10/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all "blkcipher" algorithms have been converted to "skcipher", remove the blkcipher algorithm type. The skcipher (symmetric key cipher) algorithm type was introduced a few years ago to replace both blkcipher and ablkcipher (synchronous and asynchronous block cipher). The advantages of skcipher include: - A much less confusing name, since none of these algorithm types have ever actually been for raw block ciphers, but rather for all length-preserving encryption modes including block cipher modes of operation, stream ciphers, and other length-preserving modes. - It unified blkcipher and ablkcipher into a single algorithm type which supports both synchronous and asynchronous implementations. Note, blkcipher already operated only on scatterlists, so the fact that skcipher does too isn't a regression in functionality. - Better type safety by using struct skcipher_alg, struct crypto_skcipher, etc. instead of crypto_alg, crypto_tfm, etc. - It sometimes simplifies the implementations of algorithms. Also, the blkcipher API was no longer being tested. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: skcipher - remove crypto_has_ablkcipher()Eric Biggers2019-11-011-1/+1
| | | | | | | | | | crypto_has_ablkcipher() has no users, and it does the same thing as crypto_has_skcipher() anyway. So remove it. This also removes the last user of crypto_skcipher_type() and crypto_skcipher_mask(), so remove those too.

| | | | | | | | | | The :functions: definition allows the specification of multiple function references which prevents parsing the header file multiple times.

* crypto: doc - convert crypto API documentation to SphinxStephan Mueller2016-12-131-0/+203
With the conversion of the kernel crypto API DocBook to Sphinx, the monolithic document is broken up into individual documents. The documentation is unchanged with the exception of a slight reordering to keep the individual document parts self-contained.
