    Subject[PATCH 4.7 024/143] crypto: caam - fix non-hmac hashes
    Date
    4.7-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Russell King <rmk+kernel@armlinux.org.uk>

    commit a0118c8b2be9297aed8e915c60b4013326b256d4 upstream.

    Since 6de62f15b581 ("crypto: algif_hash - Require setkey before
    accept(2)"), the AF_ALG interface requires userspace to provide a key
    to any algorithm that has a setkey method. However, the non-HMAC
    algorithms are not keyed, so setting a key is unnecessary.

    Fix this by removing the setkey method from the non-keyed hash
    algorithms.

    Fixes: 6de62f15b581 ("crypto: algif_hash - Require setkey before accept(2)")
