RHBA-2015:1762 - Red Hat Enterprise Linux OpenStack Platform Bug Fix and Enhancement Advisory

Synopsis

Red Hat Enterprise Linux OpenStack Platform Bug Fix and Enhancement Advisory

Type/Severity

Bug Fix Advisory

Topic

Updated mariadb-galera, rabbitmq-server, openvswitch, openstack-selinux, openstack-trove, sos-plugins-openstack, and python-eventlet packages that resolve various issues are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 (Icehouse) 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 update addresses the following issues:

  • Previously, a call to the "sed" command within mysqld_safe.sh which was used to certain command line arguments failed to accommodate arguments which included a slash, such as the paths to the SSL key and certificate files to pass through this function. As a consequence, the mysqld_safe.sh script produced warnings of the form "unknown option to `s'". The script continued to work correctly otherwise as these arguments are not actually needed in this specific context. With this update, the call to sed has been corrected such that the SSL arguments which include slashes are properly interpreted. As a result, the warnings regarding sed are now resolved. (BZ#1134032)

  • Prior to this update, SELinux was preventing neutron from using the file system. As a consequence, neutron failed to run. Now, an appropriate rule has been added to SELinux, which allows neutron to run with SELinux in enforcing mode. (BZ#1176830)

  • With this release, mariadb-galera is rebased to version 5.5.42, fixing an issue where "duplicate key" errors would occur during INSERT statements, when performed during the period of time when database connectivity was moving to another Galera node, and when the first Galera node was entering a non-available state. (BZ#1240326)

  • Previously, the GM process would send a message for all slaves to terminate once the master process terminated, but would not wait for confirmation that the slaves had received this message before terminating itself. As a result, a slave that did not receive the termination message would detect that the master GM process had terminated, and would promote itself to master, causing the previous master process to hang indefinitely. With this update, the GM process now waits for its broadcast buffer to empty before terminating. This results in all slaves receiving the message to terminate, allowing the master process to terminate as expected. (BZ#1248081)

  • The openvswitch packages have been upgraded to upstream version 2.3.2, which provides a number of bug fixes over the previous version. (BZ#1250220)

  • The openstack-trove packages have been upgraded to upstream version 2014.1.5, which provides a number of bug fixes over the previous version. (BZ#1254705)

  • The python-oslo-messaging packages have been upgraded to upstream version 1.3.1, which provides a number of bug fixes over the previous version. (BZ#1257640)

  • Previously, there was a hot loop in the Send function if the connection was lost. As a consequence, the process consumed 100% CPU and hung indefinitely. To fix this problem, an upstream patch for the greenio module has been added, which allows the loop to exit if this condition happens. As a result, the process no longer consumes 100% CPU in a hot loop, and it does not hang. (BZ#1259841)
