Procedural macros to help writing eBPF programs using the redbpf-probes crate.

Overview

redbpf-macros is part of the redbpf project. Together with redbpf-probes, it provides an idiomatic Rust API to write programs that can be compiled to eBPF bytecode and executed by the linux in-kernel eBPF virtual machine.

To streamline the process of working with eBPF programs even further, redbpf also provides cargo-bpf - a cargo subcommand to simplify creating and building eBPF programs.

Example

#![no_std]
#![no_main]
use redbpf_probes::xdp::prelude::*;

// configure kernel version compatibility and license
program!(0xFFFFFFFE, "GPL");

#[xdp]
fn example_xdp_probe(ctx: XdpContext) -> XdpResult {

// do something here

Ok(XdpAction::Pass)
}
