How Badlock Was Discovered and Fixed

Severity analysis of vulnerabilities by experts from the information security industry is rarely based on real code review. In the ‘Badlock’ case, most read our CVE descriptions and built up a score representing a risk this CVE poses to a user. There is nothing wrong with this approach if it is done correctly.  CVEs are analyzed in isolation; as if no other issue exists. In the case of a ‘Badlock‘ there were eight CVEs. The difference is the fact that one of them was in a foundational component used by most of the code affected by the remaining seven CVEs. That very specific CVE was

Red Hat Enterprise Linux Sets Record Breaking Performance Results on New Generation of Intel Processors

Yesterday, Intel launched the Xeon E5-2600 v4 processor family with 26 new world records on industry-standard benchmarksOnce again, Intel’s innovation, driven by Moore’s law, has enabled faster computing for the enterprise world.

Red Hat and Intel have enjoyed a long history of collaboration across a full spectrum of enterprise IT – covering a wide range of use cases, from applications running on physical servers to virtualized and cloud-based deployments. It should come as no surprise that many of

Live Kernel Patching Update

In the year since I first wrote about kpatch, Red Hat’s live kernel patching project for Linux, we’ve been very busy.  Here are some of the highlights from the last year of live kernel patching development, and some clues about where we may be headed in the future.

Red Hat Enterprise Linux 7 Special Interest Group

In 2014, we kicked off a kpatch Special Interest Group (SIG) for users who are interested in trying out kpatch in a Red Hat Enterprise Linux 7 environment.  We’ve delivered kpatch fixes for several kernel CVEs, allowing users to easily apply fixes to their kernels immediately with no disruption or reboots necessary.

If you’re a Red Hat Enterprise Linux customer and are interested in joining the kpatch SIG

Red Hat Enterprise Linux: The Leading Platform for Top-Tier Performance

Since its introduction more than a decade ago, Red Hat Enterprise Linux has become the world’s leading enterprise Linux platform. Along the way it has set the industry standard for performance as most recently demonstrated by Red Hat Enterprise Linux 7 delivering multiple world record-breaking benchmark results at launch. These results showcased close collaboration between Red Hat and our ecosystem of partners.

With history as a backdrop, it should come as no surprise that many of our partners rely on Red Hat Enterprise Linux to support their ongoing benchmarking efforts. Red Hat and Intel have enjoyed a long history of collaboration across a full spectrum of all that is enterprise IT – covering everything from applications running on physical servers to virtualized and cloud-based deployments. In fact, during yesterday’s launch of the Intel Xeon E5-2600 v3 processor family

Red Hat Enterprise Linux: Beyond the World Records

In a recent post, we reviewed the 10 world record results set by Red Hat Enterprise Linux on the Intel Xeon processor E7 v2 family.  Besides showcasing the extreme capabilities of Red Hat Enterprise Linux, these performance achievements tell another compelling story – Red Hat Enterprise Linux has become an exceedingly popular choice when it comes to tough workloads.

For example, consider the share of Red Hat Enterprise Linux versus other operating systems used to produce these records. Out of 20 world record benchmark results (22 total submissions, 3 results were tied) posted by eight different OEM partners at the Intel Xeon processor E7 v2 family announcement, Red Hat Enterprise Linux was used in 12. Seventy-five percent of the hardware vendors taking part in this process chose to publish their world record benchmarks on the new family of processors using Red Hat Enterprise Linux. The chart below shows the significance of this adoption.
