Public bug reported: Not having prefix tracking for IPv6 appears to cause number of active data path flows to scale with number of active connections.
When combined with hardware offload this churn may be problematic as depending on data path type and other factors updating the hardware takes time which in turn can lead to increased dump duration and flow_limit collapse [1]. Open vSwitch enabled this by default [0] at 3.5, let's figure out how to best make this available for in use versions such as 2.17.x and 3.3.x. 0: https://github.com/openvswitch/ovs/commit/2af7cef26487d4f8d7e3237af92ca75e6798d2af 1: https://gist.github.com/matperin/d6f314fc2fbe584ad076b050f4230d99 ** Affects: openvswitch (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2165004 Title: Enable address prefix tracking for IPv6 by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/2165004/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
