Herbert Xu	20036252fc	crypto: hash - Added scatter list walking helper ... This patch adds the walking helpers for hash algorithms akin to those of block ciphers. This is a necessary step before we can reimplement existing hash algorithms using the new ahash interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2008-07-10 20:35:18 +08:00
Herbert Xu	166247f46a	crypto: hash - Removed vestigial ahash fields ... The base field in ahash_tfm appears to have been cut-n-pasted from ablkcipher. It isn't needed here at all. Similarly, the info field in ahash_request also appears to have originated from its cipher counter-part and is vestigial.

Herbert Xu	ca786dc738	crypto: hash - Fixed digest size check ... The digest size check on hash algorithms is incorrect. It's perfectly valid for hash algorithms to have a digest length longer than their block size. For example crc32c has a block size of 1 and a digest size of 4. Rather than having it lie about its block size, this patch fixes the checks to do what they really should which is to bound the digest size so that code placing the digest on the stack continue to work. HMAC however still needs to check this as it's only defined for such algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2008-07-10 20:35:17 +08:00
