RHBA-2015:1762 - 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)
