crypto: hash - Move ahash functions into crypto/hash.h All new crypto interfaces should go into individual files as much as possible in order to ensure that crypto.h does not collapse under its own weight. This patch moves the ahash code into crypto/hash.h and crypto/internal/hash.h respectively. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: ahash - Convert to new style algorithms This patch converts crypto_ahash to the new style. The old ahash algorithm type is retained until the existing ahash implementations are also converted. All ahash users will automatically get the new crypto_ahash type.

crypto: ahash - Add unaligned handling and default operations This patch exports the finup operation where available and adds a default finup operation for ahash. The operations final, finup and digest also will now deal with unaligned result pointers by copying it. Finally export/import operations are will now be exported too.

crypto: hash - Add shash interface The shash interface replaces the current synchronous hash interface. It improves over hash in two ways. Firstly shash is reentrant, meaning that the same tfm may be used by two threads simultaneously as all hashing state is stored in a local descriptor. The other enhancement is that shash no longer takes scatter list entries. This is because shash is specifically designed for synchronous algorithms and as such scatter lists are unnecessary. All existing hash users will be converted to shash once the algorithms have been completely converted. There is also a new finup function that combines update with final. This will be extended to ahash once the algorithm conversion is done. This is also the first time that an algorithm type has their own registration function. Existing algorithm types will be converted to this way in due course. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: shash - Fix digest size offset When an shash algorithm is exported as ahash, ahash will access its digest size through hash_alg_common. That's why the shash layout needs to match hash_alg_common. This wasn't the case because the alignment weren't identical. This patch fixes the problem.

crypto: hash - Add import/export interface It is often useful to save the partial state of a hash function so that it can be used as a base for two or more computations. The most prominent example is HMAC where all hashes start from a base determined by the key. Having an import/export interface means that we only have to compute that base once rather than for each message. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: shash - Export/import hash state only This patch replaces the full descriptor export with an export of the partial hash state. This allows the use of a consistent export format across all implementations of a given algorithm. This is useful because a number of cases require the use of the partial hash state, e.g., PadLock can use the SHA1 hash state to get around the fact that it can only hash contiguous data chunks.

crypto: hash - Add shash interface The shash interface replaces the current synchronous hash interface. It improves over hash in two ways. Firstly shash is reentrant, meaning that the same tfm may be used by two threads simultaneously as all hashing state is stored in a local descriptor. The other enhancement is that shash no longer takes scatter list entries. This is because shash is specifically designed for synchronous algorithms and as such scatter lists are unnecessary. All existing hash users will be converted to shash once the algorithms have been completely converted. There is also a new finup function that combines update with final. This will be extended to ahash once the algorithm conversion is done. This is also the first time that an algorithm type has their own registration function. Existing algorithm types will be converted to this way in due course. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: hash - Move ahash functions into crypto/hash.h All new crypto interfaces should go into individual files as much as possible in order to ensure that crypto.h does not collapse under its own weight. This patch moves the ahash code into crypto/hash.h and crypto/internal/hash.h respectively. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
