gue: Use checksum partial with remote checksum offload 2015-02-11T23:12:13+00:00 Tom Herbert therbert@google.com 2015-02-11T00:30:33+00:00 fe881ef11cf0220f118816181930494d484c4883 Change remote checksum handling to set checksum partial as default behavior. Added an iflink parameter to configure not using checksum partial (calling csum_partial to update checksum). Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S.

gue: Receive side for Generic UDP Encapsulation 2014-10-03T23:53:33+00:00 Tom Herbert therbert@google.com 2014-10-03T22:48:09+00:00 37dd0247797b168ad1cc7f5dbec825a1ee66535b This patch adds support receiving for GUE packets in the fou module. The fou module now supports direct foo-over-udp (no encapsulation header) and GUE. To support this a type parameter is added to the fou netlink parameters. For a GUE socket we define gue_udp_recv, gue_gro_receive, and gue_gro_complete to handle the specifics of the GUE protocol. Most of the code to manage and configure sockets is common with the fou.

fou: Support for foo-over-udp RX path 2014-09-19T21:15:31+00:00 Tom Herbert therbert@google.com 2014-09-17T19:25:56+00:00 23461551c00628c3f3fe9cf837bf53cf8f212b63 This patch provides a receive path for foo-over-udp. This allows direct encapsulation of IP protocols over UDP. The bound destination port is used to map to an IP protocol, and the XFRM framework (udp_encap_rcv) is used to receive encapsulated packets. Upon reception, the encapsulation header is logically removed (pointer to transport header is advanced) and the packet is reinjected into the receive path with the IP protocol indicated by the mapping. Netlink is used to configure FOU ports. The configuration information includes the port number to bind to and the IP protocol corresponding to that port. This should support GRE/UDP (http://tools.ietf.org/html/draft-yong-tsvwg-gre-in-udp-encap-02), as will as the other IP tunneling protocols (IPIP, SIT).
