* AF_NETLINK Handling
*
* The AF_NETLINK address family gets mapped to AF_ROUTE.
*
* Clients of the auditing subsystem used by CentOS 4 and 5 expect to
* be able to create AF_ROUTE SOCK_RAW sockets to communicate with the
* auditing daemons. Failure to create these sockets will cause login,
* ssh and useradd, amoung other programs to fail. To trick these
* programs into working, we convert the socket domain and type to
* something that we do support. Then when sendto is called on these
* sockets, we return an error code. See lx_sendto.
*
* We have a similar issue with the newer startup code (e.g. mountall)
* which wants to setup a netlink socket to receive from udev (protocol
* NETLINK_KOBJECT_UEVENT). These apps basically poll on the socket
* looking for udev events, which will never happen in our case, so we
* let this go through and fail if the app tries to write.
