RedBPF

A Rust eBPF toolchain.

Overview

The RedBPF project is a collection of Rust libraries to work with eBPF programs. It includes:

• redbpf-probes - an idiomatic Rust API to write programs that can be compiled to eBPF bytecode and executed by the linux in-kernel eBPF virtual machine.

  

• redbpf-macros - companion crate to redbpf-probes which provides procedural macros to reduce the amount of boilerplate needed to produce eBPF programs.

  

• redbpf, a user space library that can be used to parse and load eBPF programs written using redbpf-probes and redbpf-macros.

  

• cargo-bpf, a cargo subcommand for creating, developing and building eBPF programs in Rust using the RedBPF APIs.

  

Usage

The easiest way to get started is to install cargo-bpf, see the cargo bpf documentation for more info.

Requirements

In order to build some of the code here, you will need the following:

• Linux 4.19+, with a build tree. The build tree is picked up from standard locations, or the KERNEL_SOURCE environment variable.
• LLVM 9, or an LLVM version compatible with the Rust release you're using to build
• The latest stable Rust compiler. We only promise to build with the latest stable and nightly compilers.
