    Subject[PATCH 4.14 075/496] tls: retrun the correct IV in getsockopt
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Boris Pismenny <borisp@mellanox.com>

    [ Upstream commit a1dfa6812b682eef750412dd5a90e7d38d7af068 ]

    Current code returns four bytes of salt followed by four bytes of IV.
    This patch returns all eight bytes of IV.
