Name: BPF/eBPF

Description

eBPF (which is no longer an acronym for anything), also commonly referred to as BPF, is a revolutionary technology with origins in the Linux kernel that can run sandboxed programs in a privileged context such as the operating system kernel. It is used to safely and efficiently extend the capabilities of the kernel without requiring changing kernel source code or load kernel modules.

(e)BPF is increasing being used beyond just the Linux kernel, with implementations in network interface cards, Windows, etc. As such, this effort aims to document and standardize existing (e)BPF use. The IETF should also define processes for future extensions since (e)BPF has constantly been added to over time.
