BPF Instruction Set Architecture
Overview
RFC 9669, “BPF Instruction Set Architecture”, is a Proposed Standard document published in October 2024 by D. Thaler. The canonical text is published by the RFC Editor.
Abstract
eBPF (which is no longer an acronym for anything), also commonly referred to as BPF, is a technology with origins in the Linux kernel that can run untrusted programs in a privileged context such as an operating system kernel. This document specifies the BPF instruction set architecture (ISA).
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
