Now that all "blkcipher" algorithms have been converted to "skcipher",
this series removes 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.
Eric Biggers (5):
crypto: unify the crypto_has_skcipher*() functions
crypto: remove crypto_has_ablkcipher()
crypto: rename crypto_skcipher_type2 to crypto_skcipher_type
crypto: remove the "blkcipher" algorithm type
crypto: rename the crypto_blkcipher module and kconfig option
