We are jubilant to announce the release of:
neutron 7.1.0: OpenStack Networking
This release is part of the liberty stable release series.
For more details, please see below.
7.1.0 ^^^^^
Allowed address pairs can now be cleared by passing None in addition to an empty list. This is to make it possible to use the --action=clear option with the neutron client. neutron port-update <uuid> --allowed-address-pairs action=clear
Support for MTU selection and advertisement.
New Features ************
* Use the value of the network 'mtu' attribute for the MTU of virtual network interfaces such as veth pairs, patch ports, and tap devices involving a particular network.
* Enable end-to-end support for arbitrary MTUs including jumbo frames between instances and provider networks by moving MTU disparities between flat or VLAN networks and overlay networks from layer-2 devices to layer-3 devices that support path MTU discovery (PMTUD).
* When advertise_mtu is set in the config, Neutron supports advertising the LinkMTU using Router Advertisements.
Upgrade Notes *************
* Does not change MTU for existing virtual network interfaces.
* Actions that create virtual network interfaces on an existing network with the 'mtu' attribute containing a value greater than zero could cause issues for network traffic traversing existing and new virtual network interfaces.
Bug Fixes *********
* Fixes bug 1537734
* Explicitly configure MTU of virtual network interfaces rather than using default values or incorrect values that do not account for overlay protocol overhead.
* The Linuxbridge agent now supports the ability to toggle the local ARP responder when L2Population is enabled. This ensures compatibility with the allowed-address-pairs extension. Closes bug 1445089.
Other Notes ***********
* For details please read Blueprint mtu-selection-and-advertisement (https://specs.openstack.org/openstack/neutron-specs/specs/kilo/mtu- selection-and-advertisement.html).
