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.

Locks down "BPF" which, honestly, I don't know much about. Has something to do with firewalls?

BPF (more importantly it's successor, eBPF) allows (very specific, automatically verified) programs to run in kernel space, triggered by various events. Mostly used for networking stuff.
