Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated Red Hat Enterprise MRG Realtime packages that fix several bugs are now
available for Red Hat Enterprise MRG 2.3.
Description
Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT
infrastructure for enterprise computing. MRG offers increased performance,
reliability, interoperability, and faster computing for enterprise customers.
MRG Realtime provides the highest levels of predictability for consistent
low-latency response times to meet the needs of time sensitive workloads. MRG
Realtime provides new levels of determinism by optimizing lengthy kernel code
paths to ensure that they do not become bottlenecks. This allows for better
prioritization of applications, resulting in consistent, predictable response
times for high-priority applications.
This update provides bug fixes for the following packages:
- The rt-firmware package contains the contents of the latest linux-firmware
tree from the kernel.org project for firmware blobs.
- The rteval package contains a utility for measuring various aspects of
real-time behavior on systems under load. The script unpacks the hackbench
stress test and benchmark utility, and the kernel source code from the
rteval-loads package, builds hackbench, and then goes into a loop, running
hackbench and compiling a kernel tree. During that loop, the cyclictest program
is run to measure event response times. After the run time completes, a
statistical analysis of the event response times is performed and printed to the
screen.
This update fixes the following bugs:
- Doing rpmbuild --rebuild on rt-firmware-1.2-1.el6rt.src.rpm fails unless you
add the --target noarch argument. The .spec file was modified to add
"BuildArch: noarch" to make this the default architecture for the rt-firmware
package. In addition, MRG Realtime provides several driver firmware updates.
(BZ#914811)
- For easier installation, rteval has been modified to use the python-lxml
package instead of the optional package, libxslt-python. (BZ#905850)
Users of the real-time capabilities of Red Hat Enterprise MRG 2.3, which is
layered on Red Hat Enterprise Linux 6, are advised to upgrade to these updated
packages, which fix these bugs.
