| H A D | if_tun.h | diff 05c2828c72c4eabf62376adfe27bd24797621f62 Thu Jan 14 00:17:09 CST 2010 Michael S. Tsirkin <mst@redhat.com> tun: export underlying socket
Tun device looks similar to a packet socket
in that both pass complete frames from/to userspace.
This patch fills in enough fields in the socket underlying tun driver
to support sendmsg/recvmsg operations, and message flags
MSG_TRUNC and MSG_DONTWAIT, and exports access to this socket
to modules. Regular read/write behaviour is unchanged.
This way, code using raw sockets to inject packets
into a physical device, can support injecting
packets into host network stack almost without modification.
First user of this interface will be vhost virtualization
accelerator.
