parentcrypto: inside-secure - Added support for the AES-CMAC ahash (diff)
crypto: algif_skcipher - Use chunksize instead of blocksize
When algif_skcipher does a partial operation it always process data that is a multiple of blocksize. However, for algorithms such as CTR this is wrong because even though it can process any number of bytes overall, the partial block must come at the very end and not in the middle. This is exactly what chunksize is meant to describe so this patch changes blocksize to chunksize. Fixes: 8ff590903d5f ("crypto: algif_skcipher - User-space...")
