From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The Attack Vector Controls work is now in Linux 6.17 for those new tuning knobs worked on by AMD engineer David Kaplan to make it more straight-forward for Linux server administrators and power users to more easily select the CPU security mitigations relevant to their system(s) and intended workloads

Title makes more sense in context of the first couple paragraphs.

Title make little sense to me.

A lot of the security fixes since spectre have focused on exploiting speculative execution (a key CPU performance feature) to cross security boundaries. Defeating speculative execution when switching from user to kernel space (for example) adds a lot of overhead.

The new kernel add controls so that machines that don't need to worry about these exploits to disable the performance killing fixes.
