RHBA-2017:1594 - Bug Fix Advisory

Topic

Updated OpenStack Networking packages that resolve various issues are now
available for Red Hat OpenStack Platform 10.0 (Newton) 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.).

This update re-bases the OpenStack Networking service to upstream version 9.2.0 and fixes several bugs, including:

• Previously, if the master router instance received multiple SIGHUP signals in quick succession the default L3 HA implementation (namely, keepalived) sometimes set the router to 'backup'. When this occurred, L3 connectivity was disrupted until the previous backup keepalived instance took over. To work around this behavior, the OpenStack Networking L3 agent now throttles SIGHUP signals sent to keepalived to ensure that keepalived has enough time to reload configuration. This prevents keepalived from disrupting L3 connectivity on router updates with unnecessary failovers.

(BZ#1436359)
