RHBA-2014:1528 - Bug Fix Advisory

Topic

An updated sos package that fixes several bugs and adds various enhancements is
now available for Red Hat Enterprise Linux 6.

Description

The sos package contains a set of utilities that gather information from system
hardware, logs, and configuration files. The information can then be used for
diagnostic purposes and debugging.

This update fixes the following bugs:

• Depending on site-local configuration, large quantities of System Activity

Reporter (SAR) data could be present on systems. Previous versions of the sos
utility attempted to collect all data present, potentially leading to very large
report sizes and slow data collection. This update applies a size limit to both
binary and text data captured by the SAR module, and SAR data in the report are
now limited to 20 MB by default. In addition, a new "all_sar" option has been
added to the module to request the old behavior. (BZ#1001600)

• The sos utility makes use of the Red Hat Network Client Tools hardware module

to obtain information on the hardware present in the system. However, due to the
way in which the module was invoked by sos, a change in the Red Hat Network
component caused errors when running the sosreport command. The sos hardware
plug-in now imports the Red Hat Network module directly and stores the resulting
output in the report, thus fixing the bug. Now, exceptions or other errors are
no longer displayed during report processing. (BZ#1041770)

• Previous versions of the sos utility failed to correctly handle file system

exceptions resulting from out-of-space conditions. As a consequence, running the
sosreport utility with insufficient space could lead to thousands of logged
errors and creation of an unusable report tarball. With this update, all I/O
paths in sosreport correctly handle out-of-space and other fatal file system
exceptions. Now, attempting to run sos with insufficient space results in an
immediate descriptive error and the tool no longer attempts to create a report
archive. (BZ#1085042)

• Previous versions of the sos utility did not omit passwords or password

hashes in the grub.conf bootloader configuration file. Consequently, passwords
or password hashes contained in these files could be disclosed to the recipient
of an sos report archive. The sos utility now removes passwords and password
hashes from grub.conf, and the generated report archive no longer contains
password material. (BZ#1101311)

In addition, this update adds the following enhancements:

• With this update, the sos package includes support for the Samba Clustered

Trivial Database (CTDB), clustered implementation of the TDB used by Samba.
Users can now require information on the CTDB state and configuration to
diagnose problems in clustered Samba deployments. (BZ#961041)

• Depending on system configuration and fault state, some commands can become

blocked indefinitely causing the sos utility to appear unresponsive. With this
update, the sosreport utility applies a timeout when running all external
commands, so that commands that become blocked for an excessive period now
terminate with a timeout and no longer cause the main sos process to hang.
(BZ#1005703)

• Previous versions of the sos utility did not capture diagnostic data for

OpenShift Node and Broker installations. With this update, configuration and
state information is collected on applicable systems. (BZ#1039755)

• Previously, information related to failed upgrades was not collected by the

sosreport command. With this update, attempted upgrades leave diagnostic data in
the host file system that can assist in determining the cause of the upgrade
problem. (BZ#1052344)

Users of sos are advised to upgrade to this updated package, which fixes these
bugs and adds these enhancements.
