The previous change to allow hashing from states other than the initial broke compilation on i386 because the inline assembly tried to squeeze a u64 into a 32-bit register. As we've already checked for 32-bit overflows we can simply truncate it to u32, or unsigned long so that we don't truncate at all on x86-64. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

If cryptd_alloc_instance() fails, the return value is uninitialized. This patch fixes this by setting the return value. Signed-off-by: NSteffen Klassert <steffen.klassert@secunet.com> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

The crypto4xx SHA implementation keeps the hash state in the tfm data structure. This breaks a fundamental requirement of ahash implementations that they must be reentrant. This patch disables the broken implementation. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

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.

We currently use GFP_ATOMIC in the unaligned setkey function to allocate the temporary aligned buffer. Since setkey must be called in a sleepable context, we can use GFP_KERNEL instead. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

When we encounter an unaligned pointer we are supposed to copy it to a temporary aligned location. However the temporary buffer isn't aligned properly. This patch fixes that. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

Some unaligned buffers on the stack weren't zapped properly which may cause secret data to be leaked. This patch fixes them by doing a zero memset. It is also possible for us to place random kernel stack contents in the digest buffer if a digest operation fails. This is fixed by only copying if the operation succeeded.

Now that all ahash implementations have been converted to the new ahash type, we can remove old_ahash_alg and its associated support. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch changes crypto4xx to use the new style ahash type. In particular, we now use ahash_alg to define ahash algorithms instead of crypto_alg. This is achieved by introducing a union that encapsulates the new type and the existing crypto_alg structure. They're told apart through a u32 field containing the type value.

This patch adds a mask parameter to complement the existing type parameter. This is useful when instantiating algorithms that require a mask other than the default, e.g., ahash algorithms. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

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. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch converts the padlock-sha implementation to shash. In doing so the existing mechanism of storing the data until final is no longer viable as we do not have a way of allocating data in crypto_shash_init and then reliably freeing it. This is just as well because a better way of handling the problem is to hash everything but the last chunk using normal sha code and then provide the intermediate result to the padlock device. This is good enough because the primary application of padlock-sha is IPsec and there the data is laid out in the form of an hmac header followed by the rest of the packet. In essence we can provide all the data to the padlock as the hmac header only needs to be hashed once. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

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.
