RHBA-2013:1358 - Bug Fix Advisory

Topic

Updated conga packages that fix several bugs are now available for Red Hat
Enterprise Linux 5.

Description

Conga is an agent/server architecture for remote administration of systems. It
provides a convenient method for creating and managing clusters built with Red
Hat Cluster Suite. It also offers an interface for managing sophisticated
storage configurations like those often built to support clusters. The agent
component is called "ricci", and the server (or the web-based front end of the
Conga cluster management) is called "luci".

This update fixes the following bugs:

• Previously, a non-English locale caused luci, to display improper copyright

information in the pages' footer. The respective template has been fixed so as
not to translate the application-specific part and the whole footer now displays
information correctly even in non-English locales. (BZ#514679)

• Prior to this update, luci contained non-visual links dedicated to better

browsing experience in the agents supporting it, such as navigation to the site
map, the access to which resulted in an error. The page titles also contained
some rare inconsistencies. The luci templates clean-up has been provided to fix
respective corner cases. (BZ#853018)

• For extremely large cluster.conf files, the luci serializer could not handle

the complexity of a cluster configuration object as the serializer run into the
recursion depth limit. Consequently, error messages were returned in luci.
Caching of the object representing cluster configuration has been abandoned so
that this error no longer occurs. (BZ#872645)

• Previously, the ricci(8) and luci_admin(8) manual pages of the respective

conga packages were installed with incorrect permissions. File permissions have
been corrected in the installation procedure and the manual pages are now
installed correctly. (BZ#883804)

• Each time luci was used to start or restart a cluster, or to have previously

inactivated node rejoined the cluster, it made cluster services such as cman,
rgmanager or clvmd enabled on boot on the respective cluster nodes. This can
interfere with the user's preferences, for instance, when running a 2-nodes
cluster without a quorum disk and having the services disabled on purpose on one
of the nodes to prevent fence races. To avoid this, Conga has been changed so
that it no longer modifies the existing settings in the mentioned cases, while
still enabling the services when the cluster is created or a new node is added.
(BZ#887170)

• Previously, a segmentation fault occurred in the ricci daemon when processing

cluster.conf files with very large values. This was caused by allocating large
amounts of memory that were not available on the stack. A patch has been
introduced to allocate memory on the heap and provide an error message if not
enough memory is available. As a result, the segmentation fault no longer
occurs. (BZ#965785)

Users of conga are advised to upgrade to these updated packages, which fix these
bugs.
