RHBA-2017:0277 - 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.)

This update addresses the following issue:

• Prior to this update, data database layer errors were not caught by the server component, resulting in errors during port status update requests (for particular race conditions). Consequently, on occasion, an L2 agent that attempted to update a port status could have caught an unexpected error from neutron-server, triggering a costly full resync of port data.

With this update, neutron-server now correctly catches the previously missed error and repeats the failed operation.
As a result, the L2 agent is no longer exposed to the unexpected error, and will not trigger full resync in this particular scenario. (BZ#1369722)

Solution
