* vxlan: Call udp_flow_src_portTom Herbert2014-07-071-4/+1
| | | | | | | | | In vxlan and OVS vport-vxlan call common function to get source port for a UDP tunnel. Removed vxlan_src_port since the functionality is now in udp_flow_src_port. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* vxlan: Add support for UDP checksums (v4 sending, v6 zero csums)Tom Herbert2014-06-041-1/+1
| | | | | | | | | | | Added VXLAN link configuration for sending UDP checksums, and allowing TX and RX of UDP6 checksums. Also, call common iptunnel_handle_offloads and added GSO support for checksums. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: rename local_df to ignore_dfWANG Cong2014-05-121-1/+1
| | | | | | | | | | | | | As suggested by several people, rename local_df to ignore_df, since it means "ignore df bit if it is set".

* vxlan: add x-netns supportNicolas Dichtel2014-04-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | This patch allows to switch the netns when packet is encapsulated or decapsulated. The vxlan socket is openned into the i/o netns, ie into the netns where encapsulated packets are received. The socket lookup is done into this netns to find the corresponding vxlan tunnel. After decapsulation, the packet is injecting into the corresponding interface which may stand to another netns. When one of the two netns is removed, the tunnel is destroyed. Configuration example: ip netns add netns1 ip netns exec netns1 ip link set lo up ip link add vxlan10 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0 ip link set vxlan10 netns netns1 ip netns exec netns1 ip addr add 192.168.0.249/24 broadcast 192.168.0.255 dev vxlan10 ip netns exec netns1 ip link set vxlan10 up Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.

Major changes are: * Restructure flow handling code to be more logically organized and easier to read. * Rehashing of the flow table is moved from a workqueue to flow installation time. Before, heavy load could block the workqueue for excessive periods of time. * Additional debugging information is provided to help diagnose megaflows. * It's now possible to match on TCP flags. ==================== Signed-off-by: David S.

* | net ipv4: Convert ipv4.ip_local_port_range to be per netns v3Eric W. Biederman2013-09-301-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | - Move sysctl_local_ports from a global variable into struct netns_ipv4. - Modify inet_get_local_port_range to take a struct net, and update all of the callers. - Move the initialization of sysctl_local_ports into sysctl_net_ipv4.c:ipv4_sysctl_init_net from inet_connection_sock.c v2: - Ensure indentation used tabs - Fixed ip.h so it applies cleanly to todays net-next v3: - Compile fixes of strange callers of inet_get_local_port_range. This patch now successfully passes an allmodconfig build.

* openvswitch: Add vxlan tunneling support.Pravin B Shelar2013-08-201-0/+204
Following patch adds vxlan vport type for openvswitch using vxlan api. So now there is vxlan dependency for openvswitch.
