[CRYPTO] api: Split out low-level API The crypto API is made up of the part facing users such as IPsec and the low-level part which is used by cryptographic entities such as algorithms. This patch splits out the latter so that the two APIs are more clearly delineated. As a bonus the low-level API can now be modularised if all algorithms are built as modules.

[CRYPTO] api: Added spawns Spawns lock a specific crypto algorithm in place. They can then be used with crypto_spawn_tfm to allocate a tfm for that algorithm.

[CRYPTO] api: Allow algorithm lookup by type This patch also adds the infrastructure to pick an algorithm based on their type. For example, this allows you to select the encryption algorithm "aes", instead of any algorithm registered under the name "aes". For now this is only accessible internally.

crypto: api - Do not displace newly registered algorithms We have a mechanism where newly registered algorithms of a higher priority can displace existing instances that use a different implementation of the same algorithm with a lower priority.

[CRYPTO] api: Do not remove users unless new algorithm matches As it is whenever a new algorithm with the same name is registered users of the old algorithm will be removed so that they can take advantage of the new algorithm. This presents a problem when the new algorithm is not equivalent to the old algorithm. In particular, the new algorithm might only function on top of the existing one. Hence we should not remove users unless they can make use of the new algorithm. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: api - Fix algorithm test race that broke aead initialisation When we complete a test we'll notify everyone waiting on it, drop the mutex, and then remove the test larval (after reacquiring the mutex). If one of the notified parties tries to register another algorithm with the same driver name prior to the removal of the test larval, they will fail with EEXIST as only one algorithm of a given name can be tested at any time. This broke the initialisation of aead and givcipher algorithms as they will register two algorithms with the same driver name, in sequence. This patch fixes the problem by marking the larval as dead before we drop the mutex, and also ignoring all dead or dying algorithms on the registration path.

crypto: api - Fix algorithm test race that broke aead initialisation When we complete a test we'll notify everyone waiting on it, drop the mutex, and then remove the test larval (after reacquiring the mutex). If one of the notified parties tries to register another algorithm with the same driver name prior to the removal of the test larval, they will fail with EEXIST as only one algorithm of a given name can be tested at any time. This broke the initialisation of aead and givcipher algorithms as they will register two algorithms with the same driver name, in sequence.

[CRYPTO] api: Explain the comparison on larval cra_name This patch adds a comment to explain why we compare the cra_driver_name of the algorithm being registered against the cra_name of a larval as opposed to the cra_driver_name of the larval. In fact larvals have only one name, cra_name which is the name that was requested by the user. The test here is simply trying to find out whether the algorithm being registered can or can not satisfy the larval. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] aead: Add authenc This patch adds the authenc algorithm which constructs an AEAD algorithm from an asynchronous block cipher and a hash. The construction is done by concatenating the encrypted result from the cipher with the output from the hash, as is used by the IPsec ESP protocol. The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm. For the above example, if a key of length 36 bytes is given, then hmac(sha1) would receive the first 20 bytes while the last 16 would be given to cbc(aes).
