RHBA-2017:2721 - Bug Fix Advisory

Topic

Updated director installer packages that resolve various issues are now
available for Red Hat OpenStack Platform 11.0 (Ocata) 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:

Changes to the puppet-horizon component:

• Some binary python modules used by Horizon were compiled with a flag that makes them use the simplified GIL state API. Since mod_wsgi uses sub-interpreters, and the simplified GIL state API is not re-entrant, this results in the mod_wsgi locking up and hanging, making the dashboard unavailable.

Added "WSGIApplicationGroup %{GLOBAL}" to mod_wsgi configuration, which forces it to always use the main interpreter instead of sub-interpreters. With that option, mod_wsgi works correctly no matter what options were used to compile the binary python modules. The slight performance penalty is not noticeable. (BZ#1478870)

Changes to the puppet-tripleo component:

• In Highly Available IPv6 deployments, virtual IPs used for RabbitMQ may move between controller hosts during an upgrade. A bug in the creation of these IPv6 IPs causes them to be used as source addresses for RabbitMQ's connections. As a result, RabbitMQ will crash and may be unable to automatically recover its cluster.

To return to normal operation, restart RabbitMQ on the affected controller hosts, as well as any services which depend on RabbitMQ and do not automatically reconnect. (BZ#1445905)
