  • Linux Kernel

    eBPF Runtime

    The Linux kernel contains the eBPF runtime required to run eBPF programs. It implements the bpf(2) system call for interacting with programs, maps, BTF and various attachment points where eBPF programs can be executed from. The kernel contains a eBPF verifier in order to check programs for safety and a JIT compiler to translate programs to native machine code. User space tooling such as bpftool and libbpf are also maintained as part of the upstream kernel.

  • LLVM Compiler

    eBPF Backend

    The LLVM compiler infrastructure contains the eBPF backend required to translate programs written in a C-like syntax to eBPF instructions. LLVM generates eBPF ELF files which contain program code, map descriptions, relocation information and BTF meta data. These ELF files contain all necessary information for eBPF loaders such as libbpf to prepare and load programs into the Linux kernel. The LLVM project also contains additional developer tools such as an eBPF object file disassembler.

  • GCC Compiler

    eBPF Backend

    The GCC compiler comes with an eBPF backend starting from GCC 10. Up to that point, LLVM has been the only compiler which supports generating eBPF ELF files. The GCC port is roughly equivalent to the LLVM eBPF support. There are some missing bits of functionality but the GCC community is working to close these gaps over time. GCC also contains eBPF binutils as well as eBPF gdb support for debugging of eBPF code that is traditionally consumed by the Linux kernel. Included as part of this is an eBPF simulator for gdb.

  • bpftool

    Command-line tool to inspect and manage eBPF objects

    Powered by libbpf, bpftool is the reference utility to quickly inspect and manage BPF objects on a Linux system. Use it to list, dump, or load eBPF programs and maps, to generate skeletons for eBPF applications, to statically link eBPF programs from different object files, or to perform various other eBPF-related tasks.

  • C++

    • libbpf

      libbpf is a C/C++ based library which is maintained as part of the upstream Linux kernel. It contains an eBPF loader which takes over processing LLVM generated eBPF ELF files for loading into the kernel. libbpf received a major boost in capabilities and sophistication and closed many existing gaps with BCC as a library. It also supports important features not available in BCC such as global variables and BPF skeletons.

  • Golang

    • eBPF

      eBPF is designed as 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.

    • libbpfgo

      libbpfgo is a Go wrapper around libbpf. It supports BPF CO-RE and its goal is to be a complete implementation of libbpf APIs. It uses CGo to call into linked versions of libbpf.

  • Rust

    • aya

      aya is an eBPF library built with a focus on operability and developer experience. It allows for both eBPF programs and their userspace programs to be written in Rust.

    • libbpf-rs is a safe, idiomatic, and opinionated wrapper API around libbpf written in Rust. libbpf-rs, together with libbpf-cargo (libbpf cargo plugin) allows to write 'compile once run everywhere' (CO-RE) eBPF programs.

  • Utilities for use with XDP

    libxdp is an XDP-specific library that sits on top of libbpf and implements a couple of XDP features: it supports loading of multiple programs to run in sequence on the same interface, and it contains helper functions for configuring AF_XDP sockets as well as reading and writing packets from these sockets.

  • PcapPlusPlus

    C++ library for capturing, parsing and crafting network packets

    PcapPlusPlus is a multi-platform C++ library for capturing, parsing and crafting network packets. It is designed to be efficient, powerful and easy to use. PcapPlusPlus enables capturing and sending network packets through a variaty of packet processing engines, one of them is eBPF AF_XDP sockets. It features an easy-to-use C++ interface for creating AF_XDP sockets, making it easy to send and receive packets through them.

  • 这些项目是否属于 eBPF 基金会 ?

    • 本页列出了许多使用 eBPF 作为底层核心技术的开源项目。这些项目并不都在 eBPF 基金会 之下，但在此列出，以展示当前 eBPF 项目的概况。.

  • 添加你的项目

    1. 确保项目符合列出的要求。见下文。
    2. 提交 Pull Request 并提供所需的信息。使用一个已经列出的项目作为模板。应用程序的排序基于 Github 星标的数量(从高到低)，每季度更新一次。
    3. Pull Request 将由社区审核，并由一个维护者合并。如果你有任何问题，请在 Slack 上提问。

  • 您是否在维护一个已列出的项目 ?

    • 如果您正在维护列出的项目之一，并希望调整内容。在 Slack 上与我们取得联系或直接提交一个 Pull Request。

  • 被列出项目的要求

    项目可以在此页面上以“主要”或“新兴”的形式列出。被列为“新兴”的要求是：

    • 项目必须是开源的。所有源代码必须在开放源代码许可下进行许可。任何文档都必须在开放许可协议下授权。
    • 项目必须使用 eBPF 作为其基础核心技术（换句话说, 如果去掉eBPF部分, 项目将失去其目的）,或者帮助加速在生产中采用 eBPF。
    • 项目必须积极维护。
    • 项目必须对协作开放，并具有遵循开源最佳实践的治理模型。

    要被列为“主要”项目, 该项目必须满足上述所有要求, 并且：

    • 项目必须有超过 50 个贡献者。
    • 该项目必须在生产级别的环境中有大量使用用户。由于这些信息可能不容易从项目链接中发现，因此这些信息应该包含在 Pull Request 描述中。
