| | A short tagline from the book Learning eBPF describes eBPF as a revolutionary kernel technology that allows developers to write custom code that can be loaded into the kernel dynamically, changing the way the kernel behaves. The key word in this phrase is dynamically. eBPF allows you to write custom code that changes the way the kernel behaves without having to implement a kernel module or integrate your code directly into the kernel.

| | [AI summary] The article provides an introduction to XDP (eXpress Data Path) and eBPF (extended Berkeley Packet Filter), explaining their roles in improving packet processing performance in Linux. It discusses the limitations of kernel bypass techniques and how XDP addresses them by executing network functions within the kernel. The article also delves into the history and evolution of BPF, highlighting its transition from a packet filtering tool to a versatile virtual machine used for various kernel tasks. Examples of eBPF usage, such as the tracex4 program, are provided to illustrate its capabilities.
