Currently, we read/write the state in CPU endian, but on the final request, we convert its endian according to the requested algorithm. (md5 is little endian, SHA are big endian.) Always keep creq->state in CPU native endian format, and perform the necessary conversion when copying the hash to the result.

This patch implements the AES key wrapping as specified in NIST SP800-38F and RFC3394. The implementation covers key wrapping without padding. IV handling: The caller does not provide an IV for encryption, but must obtain the IV after encryption which would serve as the first semblock in the ciphertext structure defined by SP800-38F. Conversely, for decryption, the caller must provide the first semiblock of the data as the IV and the following blocks as ciphertext. The key wrapping is an authenticated decryption operation. The caller will receive EBADMSG during decryption if the authentication failed. Albeit the standards define the key wrapping for AES only, the template can be used with any other block cipher that has a block size of 16 bytes. During initialization of the template, that condition is checked. Any cipher not having a block size of 16 bytes will cause the initialization to fail.

The mxs-dcp driver relies on the stmp_reset_block() helper function, which is provided by CONFIG_STMP_DEVICE. This symbol is always set on MXS, but the driver can now also be built for MXC (i.MX6), which results in a built error if no other driver selects STMP_DEVICE: drivers/built-in.o: In function `mxs_dcp_probe': vf610-ocotp.c:(.text+0x3df302): undefined reference to `stmp_reset_block' This adds the 'select', like all other stmp drivers have it.

As all the import functions and export functions are virtually identical, factor out their common parts into a generic mv_cesa_ahash_import() and mv_cesa_ahash_export() respectively. This performs the actual import or export, and we pass the data pointers and length into these functions. We have to switch a % const operation to do_div() in the common import function to avoid provoking gcc to use the expensive 64-bit by 64-bit modulus operation.

Attempting to use the sha1 digest for openssh via openssl reveals that the result from the hash is wrong: this happens when we export the state from one socket and import it into another via calling accept(). The reason for this is because the operation is reset to "initial block" state, whereas we may be past the first fragment of data to be hashed. Arrange for the operation code to avoid the initialisation of the state, thereby preserving the imported state.

When a AF_ALG fd is accepted a second time (hence hash_accept() is used), hash_accept_parent() allocates a new private context using sock_kmalloc(). This context is uninitialised. After use of the new fd, we eventually end up with the kernel complaining: marvell-cesa f1090000.crypto: dma_pool_free cesa_padding, c0627770/0 (bad dma) where c0627770 is a random address. Poisoning the memory allocated by the above sock_kmalloc() produces kernel oopses within the marvell hash code, particularly the interrupt handling. The following simplfied call sequence occurs: hash_accept() crypto_ahash_export() marvell hash export function af_alg_accept() hash_accept_parent() <== allocates uninitialised struct hash_ctx crypto_ahash_import() marvell hash import function hash_ctx contains the struct mv_cesa_ahash_req in its req.__ctx member, and, as the marvell hash import function only partially initialises this structure, we end up with a lot of members which are left with whatever data was in memory prior to sock_kmalloc(). Add zero-initialisation of this structure.

Several of the algorithms in marvell/hash.c have a statesize of zero. When an AF_ALG accept() on an already-accepted file descriptor to calls into hash_accept(), this causes: char state[crypto_ahash_statesize(crypto_ahash_reqtfm(req))]; to be zero-sized, but we still pass this to: err = crypto_ahash_export(req, state); which proceeds to write to 'state' as if it was a "struct md5_state", "struct sha1_state" etc. Add the necessary initialisers for the .statesize member.

Samples are documented to be available every 0.667us, so in theory the 8 sample deep FIFO should take 5.336us to fill.
