RHBA-2017:3070 - Bug Fix Advisory

Topic

Updated OpenStack Networking packages that resolve various issues are now
available for Red Hat Enterprise Linux OpenStack Platform 6.0 (Juno) 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:

• The ip_gre kernel module introduces two new interfaces to every network namespace. With Red Hat Enterprise Linux 7.3, the ip_gre kernel module is a dependency of vport_gre module used by the openvswitch module. These two devices cannot be removed from namespace and neutron-netns-cleanup only removes the namespace if it does not contain any network interfaces. Having those devices present skips the namespace removal. This fix ensures the two new ip_gre interfaces are ignored, similar to loopback interfaces. Now the namespace is considered empty regardless of whether it contains loopback and gre interfaces and is cleaned up. (BZ#1382725)
