netrom: fix info leak via msg_name in nr_recvmsg()
[ Upstream commits 3ce5efad47b62c57a4f5c54248347085a750ce0e and c802d759623acbd6e1ee9fbdabae89159a513913 ] In case msg_name is set the sockaddr info gets filled out, as requested, but the code fails to initialize the padding bytes of struct sockaddr_ax25 inserted by the compiler for alignment. Also the sax25_ndigis member does not get assigned, leaking four more bytes. Both issues lead to the fact that the code will leak uninitialized kernel stack bytes in net/socket.c. Fix both issues by initializing the memory with memset(0). Signed-off-by: Mathias Krause <minipli@googlemail.com> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.
