Mathias Krause 60085c3d00 tipc: fix info leaks via msg_name in recv_msg/recv_stream ... The code in set_orig_addr() does not initialize all of the members of struct sockaddr_tipc when filling the sockaddr info -- namely the union is only partly filled. This will make recv_msg() and recv_stream() -- the only users of this function -- leak kernel stack memory as the msg_name member is a local variable in net/socket.c. Additionally to that both recv_msg() and recv_stream() fail to update the msg_namelen member to 0 while otherwise returning with 0, i.e. "success". This is the case for, e.g., non-blocking sockets. This will lead to a 128 byte kernel stack leak in net/socket.c. Fix the first issue by initializing the memory of the union with memset(0). Fix the second one by setting msg_namelen to 0 early as it will be updated later if we're going to fill the msg_name member.
