Another one for the cipher museum: split off DES core processing into
a separate module so other drivers (mostly for crypto accelerators)
can reuse the code without pulling in the generic DES cipher itself.
This will also permit the cipher interface to be made private to the
crypto API itself once we move the only user in the kernel (CIFS) to
this library interface.

Many ahash algorithms set .cra_flags = CRYPTO_ALG_TYPE_AHASH. But this
is redundant with the C structure type ('struct ahash_alg'), and
crypto_register_ahash() already sets the type flag automatically,
clearing any type flag that was already there. Apparently the useless
assignment has just been copy+pasted around.
So, remove the useless assignment from all the ahash algorithms.
This patch shouldn't change any actual behavior.

We need to consistently enforce that keyed hashes cannot be used without
setting the key. To do this we need a reliable way to determine whether
a given hash algorithm is keyed or not. AF_ALG currently does this by
checking for the presence of a ->setkey() method. However, this is
actually slightly broken because the CRC-32 algorithms implement
->setkey() but can also be used without a key. (The CRC-32 "key" is not
actually a cryptographic key but rather represents the initial state.
If not overridden, then a default initial state is used.)
Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which
indicates that the algorithm has a ->setkey() method, but it is not
required to be called. Then set it on all the CRC-32 algorithms.
The same also applies to the Adler-32 implementation in Lustre.
Also, the cryptd and mcryptd templates have to pass through the flag
from their underlying algorithm.

gcc warns that the length for the extra unaligned data in the hash
function may be used unaligned. In theory this could happen if
we pass a zero-length sg_list, or if sg_is_last() was never true:
In file included from drivers/crypto/stm32/stm32-hash.c:23:
drivers/crypto/stm32/stm32-hash.c: In function 'stm32_hash_one_request':
include/uapi/linux/kernel.h:12:49: error: 'ncp' may be used uninitialized in this function [-Werror=maybe-uninitialized]
#define __KERNEL_DIV_ROUND_UP(n, d) (((n) + (d) - 1) / (d))
Neither of these can happen in practice, so the warning is harmless.
However while trying to suppress the warning, I noticed multiple
problems with that code:
- On big-endian kernels, we byte-swap the data like we do for
register accesses, however this is a data stream and almost
certainly needs to use a single writesl() instead of series
of writel() to give the correct hash.
- If the length is not a multiple of four bytes, we skip the
last word entirely, since we write the truncated length
using stm32_hash_set_nblw().
- If we change the code to round the length up rather than
down, the last bytes contain stale data, so it needs some
form of padding.
This tries to address all four problems, by correctly
initializing the length to zero, using endian-safe copy
functions, adding zero-padding and passing the padded length.
I have done no testing on this patch, so please review
carefully and if possible test with an unaligned length
and big-endian kernel builds.
