Mathias Krause 4b5223be98 packet: fix heap info leak in PACKET_DIAG_MCLIST sock_diag interface ... [ Upstream commit 309cf37fe2 ] Because we miss to wipe the remainder of i->addr[] in packet_mc_add(), pdiag_put_mclist() leaks uninitialized heap bytes via the PACKET_DIAG_MCLIST netlink attribute. Fix this by explicitly memset(0)ing the remaining bytes in i->addr[].
