Overview

eBPF is a technology that allows running user-supplied programs inside the Linux kernel. For more info see https://ebpf.io/what-is-ebpf.

Aya is an eBPF library built with a focus on operability and developer experience. It does not rely on libbpf nor bcc - it's built from the ground up purely in Rust, using only the libc crate to execute syscalls. With BTF support and when linked with musl, it offers a true compile once, run everywhere solution, where a single self-contained binary can be deployed on many linux distributions and kernel versions.

Some of the major features provided include:

  • Support for the BPF Type Format (BTF), which is transparently enabled when supported by the target kernel. This allows eBPF programs compiled against one kernel version to run on different kernel versions without the need to recompile.
  • Support for function call relocation and global data maps, which allows eBPF programs to make function calls and use global variables and initializers.
  • Async support with both tokio and async-std.
  • Easy to deploy and fast to build: aya doesn't require a kernel build or compiled headers, and not even a C toolchain; a release build completes in a matter of seconds.

Example

Aya supports a large chunk of the eBPF API. The following example shows how to use a BPF_PROG_TYPE_CGROUP_SKB program with aya:

use std::fs::File;
use aya::Bpf;
use aya::programs::{CgroupSkb, CgroupSkbAttachType};

// load the BPF code
let mut bpf = Bpf::load_file("bpf.o")?;

// get the `ingress_filter` program compiled into `bpf.o`.
let ingress: &mut CgroupSkb = bpf.program_mut("ingress_filter")?.try_into()?;

// load the program into the kernel
ingress.load()?;

// attach the program to the root cgroup. `ingress_filter` will be called for all
// incoming packets.
let cgroup = File::open("/sys/fs/cgroup/unified")?;
ingress.attach(cgroup, CgroupSkbAttachType::Ingress)?;
