If anyone has any objections, please let me know. ------------------ From: Dan Carpenter [ 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.
