Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated OpenStack Dashboard packages that resolve various issues are now
available for Red Hat OpenStack Platform 8.0 (Liberty) for RHEL 7.
Description
Red Hat 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 Dashboard
OpenStack Dashboard (horizon) provides administrators and users a graphical
interface to access, provision, and automate cloud-based resources. The
dashboard allows cloud administrators to get an overall view of the size
and state of the cloud, and it provides end-users a self-service portal to
provision their own resources within the limits set by administrators.
This update addresses the following issue:
- Previously, some binary Python modules used by Horizon were compiled with a flag that requires them to use the simplified GIL state API. Since mod_wsgi uses sub-interpreters and the simplified GIL state API is not reentrant, it results in the mod_wsgi locking up. Consequently the dashboard is unavailable.
With this update, the mod_wsgi configuration was changed, forcing mod_wsgi to use the main interpreter instead of sub-interpreters. As a result, mod_wsgi works correctly.
Solution
Before applying this update, ensure all previously released errata relevant
to your system have been applied.
Red Hat OpenStack Platform 8 runs on Red Hat Enterprise Linux 7.4.
