Subject: af_key: fix info leaks in notify messages
From: Mathias Krause <minipli@xxxxxxxxxxxxxx>
[ Upstream commit a5cc68f3d63306d0d288f31edfc2ae6ef8ecd887 ]
key_notify_sa_flush() and key_notify_policy_flush() miss to initialize
the sadb_msg_reserved member of the broadcasted message and thereby
leak 2 bytes of heap memory to listeners. Fix that.
