Contributors list




eBPF is a pure Go library that provides utilities for loading, compiling, and debugging eBPF programs. It has minimal external dependencies and is intended to be used in long running processes.

The library is maintained by Cloudflare and Cilium.

See for other projects from the eBPF ecosystem.

Getting Started

A small collection of Go and eBPF programs that serve as examples for building your own tools can be found under examples/.

Contributions are highly encouraged, as they highlight certain use cases of eBPF and the library, and help shape the future of the project.

Getting Help

Please join the #ebpf-go channel on Slack if you have questions regarding the library.


This library includes the following packages:

  • asm contains a basic assembler, allowing you to write eBPF assembly instructions directly within your Go code. (You don't need to use this if you prefer to write your eBPF program in C.)
  • cmd/bpf2go allows compiling and embedding eBPF programs written in C within Go code. As well as compiling the C code, it auto-generates Go code for loading and manipulating the eBPF program and map objects.
  • link allows attaching eBPF to various hooks
  • perf allows reading from a
  • ringbuf allows reading from a
  • features implements the equivalent of
    bpftool feature probe
    for discovering BPF-related kernel features using native Go.
  • rlimit provides a convenient API to lift the
    constraint on kernels before 5.11.


Regenerating Testdata


in the root of this repository to rebuild testdata in all subpackages. This requires Docker, as it relies on a standardized build environment to keep the build output stable.

It is possible to regenerate data using Podman by overriding the


The toolchain image build files are kept in testdata/docker/.
