Practical BPF examples

This git repository contains a diverse set of practical BPF examples that solve (or demonstrate) a specific use-case using BPF.

It is meant to ease doing rapid prototyping and development, writing C-code BPF programs using libbpf. The goal is to make is easier for developers to get started coding.

Many developers struggle to get a working BPF build environment. The repo enviroment makes it easy to build/compile BPF programs by doing the necessary libbpf setup transparently and detect missing compile dependencies (via the (configure)[configure] script). It is a declared goal to make BPF programming more consumable by detecting and reporting issues (when possible).
