    Subject[PATCH 4.14 096/165] crypto: inside-secure - fix the extra cache computation
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Antoine Tenart <antoine.tenart@bootlin.com>

    [ Upstream commit c1a8fa6e240ed4b99778d48ab790743565cb61c8 ]

    This patch fixes the extra cache computation when the queued data is a
    multiple of a block size. This fixes the hash support in some cases.

    Fixes: 809778e02cd4 ("crypto: inside-secure - fix hash when length is a multiple of a block")
