[ Upstream commit a5596d6332787fd383b3b5427b41f94254430827 ]

This patch adds a way for ahash users to determine whether a key
is required by a crypto_ahash transform.

crypto: LLVMLinux: Add macro to remove use of VLAIS in crypto code

2014-10-14T08:51:22+00:00

Add a macro which replaces the use of a Variable Length Array In Struct (VLAIS)
with a C99 compliant equivalent. This macro instead allocates the appropriate
amount of memory using an char array.

The new code can be compiled with both gcc and clang.

struct shash_desc contains a flexible array member member ctx declared with
CRYPTO_MINALIGN_ATTR, so sizeof(struct shash_desc) aligns the beginning
of the array declared after struct shash_desc with long long.

No trailing padding is required because it is not a struct type that can
be used in an array.

The CRYPTO_MINALIGN_ATTR is required so that desc is aligned with long long
as would be the case for a struct containing a member with
CRYPTO_MINALIGN_ATTR.

If you want to get to the ctx at the end of the shash_desc as before you can do
so using shash_desc_ctx(shash)

crypto: shash - Fix digest size offset

2009-07-15T13:16:05+00:00

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: ahash - Add unaligned handling and default operations

2009-07-15T04:40:40+00:00

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: ahash - Remove old_ahash_alg

2009-07-14T12:29:57+00:00

Now that all ahash implementations have been converted to the new
ahash type, we can remove old_ahash_alg and its associated support.
