crypto: hash - Fix handling of unaligned buffers
The correct way to calculate the start of the aligned part of an unaligned buffer is: offset = ALIGN(offset, alignmask + 1); However, crypto_hash_walk_done() has: offset += alignmask - 1; offset = ALIGN(offset, alignmask + 1); which actually skips a whole block unless offset % (alignmask + 1) == 1. This patch fixes the problem. Signed-off-by: Szilveszter Ördög <slipszi@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
