* udp: Do not require sock in udp_tunnel_xmit_skbTom Herbert2015-01-241-6/+6
| | | | | | | | | | | | | | The UDP tunnel transmit functions udp_tunnel_xmit_skb and udp_tunnel6_xmit_skb include a socket argument. The socket being passed to the functions (from VXLAN) is a UDP created for receive side. The only thing that the socket is used for in the transmit functions is to get the setting for checksum (enabled or zero). This patch removes the argument and and adds a nocheck argument for checksum setting. This eliminates the unnecessary dependency on a UDP socket for UDP tunnel transmit.

* ip: Move checksum convert defines to inetTom Herbert2015-01-051-1/+1
| | | | | | | | | | Move convert_csum from udp_sock to inet_sock. This allows the possibility that we can use convert checksum for different types of sockets and also allows convert checksum to be enabled from inet layer (what we'll want to do when enabling IP_CHECKSUM cmsg).

* udp-tunnel: Add a few more UDP tunnel APIsAndy Zhou2014-09-191-1/+52
| | | | | | | | | | | | | | | | Added a few more UDP tunnel APIs that can be shared by UDP based tunnel protocol implementation. The main ones are highlighted below. setup_udp_tunnel_sock() configures UDP listener socket for receiving UDP encapsulated packets. udp_tunnel_xmit_skb() and upd_tunnel6_xmit_skb() transmit skb using UDP encapsulation. udp_tunnel_sock_release() closes the UDP tunnel listener socket.

* udp_tunnel: Seperate ipv6 functions into its own file.Andy Zhou2014-09-191-64/+21
| | | | | | | | Add ip6_udp_tunnel.c for ipv6 UDP tunnel functions to avoid ifdefs in udp_tunnel.c Signed-off-by: Andy Zhou <azhou@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* udp: Add udp_sock_create for UDP tunnels to open listener socketTom Herbert2014-07-141-0/+100
Added udp_tunnel.c which can contain some common functions for UDP tunnels. The first function in this is udp_sock_create which is used to open the listener port for a UDP tunnel. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
