​Linux and Intel Slowly Hack Their Way to a Spectre Patch

Spectre and Meltdown are major design flaws in modern CPUs. While they're present in almost all recent processors, because Intel chips are so widely used, Intel is taking most of the heat for these bugs. Nowhere has the criticism been hotter than on the Linux Kernel Mailing List (LKML). That's...

To find and report bugs, Linux kernel developers depend on a wide community of testers.

Linux Kernel Developer: Julia Lawall

A kernel that has had nearly 83,000 patches applied will certainly have a few bugs introduced along with the new features, states the 2017 Linux Kernel Development Report, written by Jonathan Corbet and Greg Kroah-Hartman. To find and report those bugs, Linux kernel developers depend on a wide...

Meltdown and Spectre Fallout Leads to First RC9 of a Linux Kernel Since 2011

​Major Linux Redesign in the Works to Deal with Intel Security Flaw

A serious security memory problem in all Intel chips has led to Linux's developers resetting how to deal with memory. The result will be a more secure, but -- as Linux creator Linus Torvalds says -- slower operating system. Long ago, Intel made a design mistake in its 64-bit chips -- and now, all...
