RHBA-2018:0617 - Bug Fix Advisory

Topic

Updated OpenStack Networking packages that resolve various issues are now
available for Red Hat OpenStack Platform 12.0 (Pike) for RHEL 7.

Description

Red Hat OpenStack Platform provides the facilities for building, deploying
and monitoring a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware. This advisory includes
packages for:

• OpenStack Networking service

OpenStack Networking (neutron) is a virtual network service for OpenStack.
Just as OpenStack Compute (nova) provides an API to dynamically request and
configure virtual servers, OpenStack Networking provides an API to
dynamically request and configure virtual networks. These networks connect
'interfaces' from other OpenStack services (e.g. virtual NICs from Compute
VMs). The OpenStack Networking API supports extensions to provide advanced
network capabilities (e.g. QoS, ACLs, network monitoring, etc.)

Changes to the openstack-neutron component:

• A race condition occurred when updating routers that caused fixed IPv6 address to incorrectly deallocate from router ports. This fix corrects how OpenStack Networking (neutron) updates routers so that it keeps existing IPv6 allocations and other port attributes intact. (BZ#1486324)
• neutron-ovs-cleanup exceeded the three hour timeout on large OVS databases. This left the OVS database only partially cleaned. This fix changes how the cleanup function looks up ports on an OVS bridge. This significantly reduces the time needed to clean the database. (BZ#1541494)

Changes to the openstack-neutron-lbaas component:

• OpenStack Networking (neutron) LBaaS command took a long time to execute. This fix refines the queries and speeds up the execution of the LBaaS commands. (BZ#1546710)

Changes to the python-networking-bigswitch component:

• Upgrading OpenStack Networking (neutron) to Red Hat OpenStack Platform 12 would fail due to a database migration file issue. This fix corrects the migration files needed for the neutron database upgrade. (BZ#1523633)

Solution

Before applying this update, ensure all previously released errata relevant
to your system have been applied.
