** asadoughi: ml2 unit test coverage bugs filed, tagged: https://bugs.launchpad.net/neutron/+bugs?field.tag=ml2-unit-test-coverage
 
−
** rkukura Look at moving bind_port() out of the TX and send email or a WIP patch to discuss.
 
−
*** Concluded two separate transactions are required, with bind_port() between them, so that MD's bind_port can reference the port as a foreign key in its own table if needed
 
−
*** Was considering a state machine to prevent multiple threads/processes from trying to bind the same port concurrently, but now thinking its safe and much simpler to simply allow them to bind concurrently

* ML2 Binding Management
 
−
** ML2 Original vs. Bound Segment Discussion
 
−
*** Should https://review.openstack.org/#/c/62380/ be completed?
 
−
*** Is that sufficient?
 
−
*** Do we need to call update_port_precommit and update_port_postcommit for all binding changes?

* Development discussions:

** blueprint ovs-firewall-driver: progress and technical discussion
 
−
*** purpose
 
−
*** openvswitch statelessness and security groups frontend API and DB: https://etherpad.openstack.org/p/ovs-firewall-driver-stateless-2
 
−
*** ovs_neutron_agent nuances:
 
−
**** (1) firewall invoked before agent does anything in C[R]UD operations
 
−
**** (2) agent removes all flows at initialization
 
−
**** (3) not sure about ovs having atomicity like iptables-restore has (all connections might be dropped/allowed)
 
−
*** if extra time, quickly mention:
 
−
**** working on adding IPv6 flows
 
−
**** working on adding multiple ports in range (try port bitmask or N flows per N ports?)
 
−
**** of course, need to add unit/integration tests; if someone wants to help on integration tests, that would be good if that's possible
 
−
**** neutron-rootwrap-xen-dom0 bugs: https://bugs.launchpad.net/neutron/+bug/1185872/comments/3, https://bugs.launchpad.net/neutron/+bug/1259748
 
−
**** other network types: should work as-is since the tunnel OVS flows just pass it to the integration bridge where firewall flows live, but test environment not setup to do so
 
−
**** table, priority coordination: ok for now to be hard-coded in Neutron, but will need an abstraction in the future possibly

Agenda

Meeting February 19, 2014

Meeting February 12, 2014

Previous Agenda

  • Icehouse Design Summit Topic ideas
    • RPC handling in ML2 for Type and Mechanism Drivers
    • More extensible TypeDrivers for controller-based MechanismDrivers
    • Monolithic Plugin vs. ML2 MechanismDriver - current and future plugins
    • Future Directions for ML2 (orchestration, deployment, management, ...)
    • Migration from deprecated Plugins (openvswitch, linuxbridge) to ML2 - automation?
    • Add support for VXLAN multicast to the OVS agent with newer versions of OVS and Linux kernel.
    • Multi-segment provider network implementations in MechanismDrivers, specifically OVS.
    • Additional provider network attributes for controller-based plugins such as ODL for networks created outside of Neutron.

Icehouse ML2 work for reference

Questions?

General ML2 Information

Here are the current ml2-specific blueprints for havana:


These tunnel-related blueprints effect the openvswitch and/or linuxbridge agents, and the features should also (or exclusively) be supported (using both agents simultaneously where applicable) by the ml2 plugin:


These blueprints involve the ml2 MechanismDriver API:
