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

2014-10-14T08:51:22Z

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) Signed-off-by: Behan Webster Reviewed-by: Mark Charlebois Acked-by: Herbert Xu Cc: Michał Mirosław

crypto: shash - Fix digest size offset

2009-07-15T13:16:05Z

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. Signed-off-by: Herbert Xu

crypto: ahash - Add unaligned handling and default operations

2009-07-15T04:40:40Z

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. Signed-off-by: Herbert Xu

crypto: ahash - Remove old_ahash_alg

2009-07-14T12:29:57Z

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: Herbert Xu

crypto: ahash - Convert to new style algorithms

2009-07-14T07:54:07Z

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: Herbert Xu

crypto: shash - Make descsize a run-time attribute

2009-07-14T04:58:00Z

This patch changes descsize to a run-time attribute so that implementations can change it in their init functions. Signed-off-by: Herbert Xu

crypto: async - Use kzfree for requests

2009-07-12T02:46:03Z

This patch changes the kfree call to kzfree for async requests. As the request may contain sensitive data it needs to be zeroed before it can be reallocated by others. Signed-off-by: Herbert Xu

crypto: shash - Export/import hash state only

2009-07-11T10:23:32Z

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: shash - Add crypto_shash_blocksize

2009-02-18T08:48:06Z

This function is needed by algorithms that don't know their own block size, e.g., in s390 where the code is common between multiple versions of SHA. Signed-off-by: Herbert Xu
