Building an XDP eBPF Program with C and Golang: A Step-by-Step Guide is a comprehensive tutorial that walks readers through the process of building an XDP (eXpress Data Path) eBPF (extended Berkeley Packet Filter) program using C and Golang. The article provides a clear overview of XDP and eBPF, highlights the project's goal of creating a simple chaos engineering tool, and guides readers through each step of the development process. From setting up the development environment to writing the XDP eBPF program in C and the accompanying Golang application, readers will gain hands-on experience and learn important concepts such as packet processing, perf event handling, and statistics tracking. By the end of the article, readers will have a solid understanding of how to leverage XDP and eBPF for networking and performance optimization purposes
