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.

crypto_has_skcipher() and crypto_has_skcipher2() do the same thing: they
check for the availability of an algorithm of type skcipher, blkcipher,
or ablkcipher, which also meets any non-type constraints the caller
specified. And they have exactly the same prototype.
Therefore, eliminate the redundancy by removing crypto_has_skcipher()
and renaming crypto_has_skcipher2() to crypto_has_skcipher().

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.

Now that the crypto_skcipher_type() function has been removed, there's
no reason to call the crypto_type struct for skciphers
"crypto_skcipher_type2". Rename it to simply "crypto_skcipher_type".

- * DOC: Synchronous Block Cipher API
- *
- * The synchronous block cipher API is used with the ciphers of type
- * CRYPTO_ALG_TYPE_BLKCIPHER (listed as type "blkcipher" in /proc/crypto)
- *
- * Synchronous calls, have a context in the tfm. But since a single tfm can be
- * used in multiple calls and in parallel, this info should not be changeable
- * (unless a lock is used). This applies, for example, to the symmetric key.
- * However, the IV is changeable, so there is an iv field in blkcipher_tfm
- * structure for synchronous blkcipher api. So, its the only state info that can
- * be kept for synchronous calls without using a big lock across a tfm.
- *
- * The block cipher API allows the use of a complete cipher, i.e. a cipher
- * consisting of a template (a block chaining mode) and a single block cipher
- * primitive (e.g. AES).
- *
- * The plaintext data buffer and the ciphertext data buffer are pointed to
- * by using scatter/gather lists. The cipher operation is performed
- * on all segments of the provided scatter/gather lists.
- *
- * The kernel crypto API supports a cipher operation "in-place" which means that
- * the caller may provide the same scatter/gather list for the plaintext and
- * cipher text. After the completion of the cipher operation, the plaintext
- * data is replaced with the ciphertext data in case of an encryption and vice
- * versa for a decryption. The caller must ensure that the scatter/gather lists
- * for the output data point to sufficiently large buffers, i.e. multiples of
- * the block size of the cipher.

To: linux-crypto
From: Eric Biggers <ebiggers@google.com>
Now that the blkcipher algorithm type has been removed in favor of
skcipher, rename the crypto_blkcipher kernel module to crypto_skcipher,
and rename the config options accordingly:
CONFIG_CRYPTO_BLKCIPHER => CONFIG_CRYPTO_SKCIPHER
CONFIG_CRYPTO_BLKCIPHER2 => CONFIG_CRYPTO_SKCIPHER2
