From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit ff862a4668dd6dba962b1d2d8bd344afa6375683 ]

This is inspired by a5cc68f3d6 "af_key: fix info leaks in notify
messages". There are some struct members which don't get initialized
and could disclose small amounts of private information.
