2015-01-24udp: Do not require sock in udp_tunnel_xmit_skbTom Herbert1-6/+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.

2014-11-25ip6_udp_tunnel: Fix checksum calculationAlexander Duyck1-3/+1
The UDP checksum calculation for VXLAN tunnels is currently using the socket addresses instead of the actual packet source and destination addresses. As a result the checksum calculated is incorrect in some cases. Also uh->check was being set twice, first it was set to 0, and then it is set again in udp6_set_csum. This change removes the redundant assignment to 0. Fixes: acbf74a7 ("vxlan: Refactor vxlan driver to make use of the common UDP tunnel functions.")

2014-09-19udp-tunnel: Add a few more UDP tunnel APIsAndy Zhou1-0/+42
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.
