Newer versions of Qt use socket(AF_NETLINK, SOCK_DGRAM, NETLINK_ROUTE) instead of socket(AF_INET, SOCK_STREAM, IPPROTO_IP) with ioctls in order to obtain interface addresses. AppArmor's nameservice allows 'network netlink raw' for this sort of thing, but 'man 7 netlink' states that "Both SOCK_RAW and SOCK_DGRAM are valid values for socket_type. However, the netlink protocol does not distinguish between datagram and raw sockets". It is therefore a bug in the AppArmor abstraction that it is missing, so add it here.
