Bugs

Important bugs:

  • [2] neutron test_multi_prefix_slaac failing in the gate with ping failures starting around 7/22
  • [3] neutron.tests.functional.agent.test_l3_agent.MetadataL3AgentTestCase.test_access_to_metadata_proxy times out intermittently
  • [4] Referencing a lb-healthmonitor ID for the first time from Heat would fail
  • [5] migrate_to_ml2 script doesn't work for Juno release
  • [6] security groups don't work with vip and ovs plugin

• Two bugs are hurting the functional job in the gate:
  • [7] agent.test_l3_agent.MetadataL3AgentTestCase.test_access_to_metadata_proxy times out intermittently
  • [8] radvd exits -1 intermittently in test_ha_router_process_ipv6_subnets_to_existing_port

On Demand Agenda

• Concrete plan to merge back pecan work
  • Need to do this very early after Liberty-2 is cut this week
• Vendor decomposition
  • Which vendors have not started final decomposition?
    • Should we maintain a list of stragglers in devref until they are all done?
    • Send an email notice about decomposition to -dev: what should it say?
  • Does anything need to be left in the tree for packaging?
    • Currently requirements.txt is left in the vendor dir with the name of the vendor package, but no one seems to know if it is needed.
• Stable branches for networking subproject
  • networking sub-projects can perform a release
  • Working with networking-midonet as a test example
  • These projects will have a version of 1.0.0
• Liberty-3 BPs and reviews
  • https://launchpad.net/neutron/+milestone/liberty-3
  • Focus here for the remaining weeks
  • Handy dandy gerrit dashboard link: https://goo.gl/x9bO7i
  • We need to merge all of this for Liberty (or make our best shot)
  • Email to openstack-dev ML on this topic: http://lists.openstack.org/pipermail/openstack-dev/2015-August/071786.html
• nova-network compatibility tasks
  • Summit session(s) in Vancouver were very productive
  • Tasks tracked here: https://etherpad.openstack.org/p/YVR-nova-network
  • Need to find owners for a few of these
    • Rolling upgrades (mostly a grenade patch)
    • Distributed SNAT with DVR
    • "Get me a network (https://review.openstack.org/#/c/184857/) (kevinbenton to own this)
    • ARP Spoof patch series is stalled, need to make a decision on how to proceed. (kevinbenton will do this after beating requirements out of markmcclain)
• macvtap ml2 driver and agent - will land in neutron tree. Question is how to procede with agent code (scheuran)
  • Aug 17 2015 update - sc68cal is working with scheuran in this gerrit topic https://review.openstack.org/#/q/status:open+project:openstack/neutron+branch:master+topic:bug/1468803,n,z
  • 1) Copy (duplicate) required agent code like in the past.
  • 2) Extract a common base class for macvtap, linuxbridge and sriov-nic (impls are close to each other). Purpose: Sharing base agent code. Starting with macvtap only in liberty. Moving others to common base class in Mitaka. New agent base class cannot be used for OVS, as it already diverged too much from others.
    • Liberty: only methods that are obious common and only differ in details that can be abstracted (_setup_rpc, _report_state, _device_info_has_changes, _process_network_devices)
    • Mitaka: Methods that have a lot of common code, but require fruther thinking (treat_devices_added_updated, scan_devices, daemon_loop)
    • N: Having a common agent with interface drivers?
  • Modular l2 agent (spec not in a good shape) and agent extension (is just for extending existing agents) is is not an option
