    Subject[PATCH 4.19 243/361] crypto: tcrypt - fix ghash-generic speed test
    Date
    4.19-stable review patch.  If anyone has any objections, please let me know.

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

    From: Horia Geantă <horia.geanta@nxp.com>

    commit 331351f89c36bf7d03561a28b6f64fa10a9f6f3a upstream.

    ghash is a keyed hash algorithm, thus setkey needs to be called.
    Otherwise the following error occurs:
    $ modprobe tcrypt mode=318 sec=1
    testing speed of async ghash-generic (ghash-generic)
    tcrypt: test 0 ( 16 byte blocks, 16 bytes per update, 1 updates):
    tcrypt: hashing failed ret=-126

    Cc: <stable@vger.kernel.org> # 4.6+
