l2tp: fix info leak via getsockname() The L2TP code for IPv6 fails to initialize the l2tp_unused member of struct sockaddr_l2tpip6 and that for leaks two bytes kernel stack via the getsockname() syscall. Initialize l2tp_unused with 0 to avoid the info leak. Signed-off-by: Mathias Krause <minipli@googlemail.com> Cc: James Chapman <jchapman@katalix.com> Signed-off-by: David S.
