[openstack-announce] [new][neutron] neutron 7.1.0 release (liberty)

0 votes

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
--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.
