RHBA-2017:3069 - Bug Fix Advisory

Topic

Updated OpenStack Networking packages that resolve various issues are now
available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo) for
RHEL 7.

Description

Red Hat Enterprise Linux OpenStack Platform provides the facilities for
building 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:

• Due to a memory leak, keepalived consumed a large amount of memory even after killing its existing processes. It would also repeatedly update the keepalived.conf file with duplicate routes. This fix resolves this issues by separating the persistence of keepalived's virtual routes according to their role, which resolves the memory leak. (BZ#1483673)

Solution

Before applying this update, ensure all previously released errata relevant
