* ovs-router: non-Linux supportYAMAMOTO Takashi2014-12-101-6/+2
| | | | | | | | | | Refactor ovs-router so that it can work with non-Linux platforms at least in some extent, using the existing route-table code as a fallback. Known restriction: for such platforms, "ovs/router/show" command does not show "Cached" kernel routes.

* route-table-bsd: Stop caching pidYAMAMOTO Takashi2014-12-101-3/+1
| | | | | | | | | | | The cache here doesn't work anymore as the recent commit b772066ffd066d59d9ebce092f6665150723d2ad ("route-table: Remove Unregister.") made this function called before daemonizing, thus with a different pid.

* route-table: Remove Unregister.Pravin B Shelar2014-12-011-14/+2
| | | | | | | | | | | | Since dpif registering for routing table at initialization there is no need to unregister it. Following patch removes support for turning routing table notifications on and off. Due to this change OVS always listens for these notifications.

* route-table: Use classifier to store routing table.Pravin B Shelar2014-11-031-1/+2
| | | | | | | | | | | Rather than using hmap for storing routing entries we can directly use classifier which has support for priority and wildcard entries. This makes route lookup lockless. This help when we use route lookup for native tunneling.

* netdev-vport: Checks tunnel status change when route-table is reset.Alex Wang2014-05-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3e912ffcbb (netdev: Add 'change_seq' back to netdev.) added per- netdev change number for indicating status change. Future commits used this change number to optimize the netdev status update to database. However, the work also introduced the bug in the following scenario: - assume interface eth0 has address 1.2.3.4, eth1 has adddress 10.0.0.1. - assume tunnel port p1 is set with remote_ip=10.0.0.5. - after setup, 'ovs-vsctl list interface p1 status' should show the 'tunnel_egress_iface="eth1"'. - now if the address of eth1 is change to 0 via 'ifconfig eth1 0'. - expectedly, after change, 'ovs-vsctl list interface p1 status' should show the 'tunnel_egress_iface="eth0"' However, 'tunnel_egress_iface' will not be updated on current master. This is in that, the 'netdev-vport' module corresponding to p1 does not react to routing related changes. To fix the bug, this commit adds a change sequence number in the route- table module and makes netdev-vport check the sequence number for tunnel status update.
