    [CRYPTO] ablkcipher: Add distinct ABLKCIPHER type · 332f8840
    Herbert Xu authored
    Up until now we have ablkcipher algorithms have been identified as
    type BLKCIPHER with the ASYNC bit set.  This is suboptimal because
    ablkcipher refers to two things.  On the one hand it refers to the
    top-level ablkcipher interface with requests.  On the other hand it
    refers to and algorithm type underneath.
    As it is you cannot request a synchronous block cipher algorithm
    with the ablkcipher interface on top.  This is a problem because
    we want to be able to eventually phase out the blkcipher top-level
    This patch fixes this by making ABLKCIPHER its own type, just as
    we have distinct types for HASH and DIGEST.  The type it associated
    with the algorithm implementation only.
    Which top-level interface is used for synchronous block ciphers is
    then determined by the mask that's used.  If it's a specific mask
    then the old blkcipher interface is given, otherwise we go with the
    new ablkcipher interface.
