3.0-stable review patch. If anyone has any objections, please let me know. ------------------ 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. Signed-off-by: Mathias Krause <minipli@xxxxxxxxxxxxxx> Cc: Steffen Klassert <steffen.klassert@xxxxxxxxxxx> Cc: "David S.
