In this talk, we will dive into the origins, development, and transformation of eBPF. Our exploration begins with the inception of Berkeley Packet Filter in the early 1990s and its significant contributions to network packet filtering and analysis. We'll explore the motivations and considerations of Steave McCane and Van Jacobson of Lawrence Berkeley Laboratory that led to the development of BPF. Then we follow the story of its more versatile and dynamic variant eBPF, which enabled it to transcend traditional boundaries and venture into new frontiers. We'll briefly delve into the technical underpinnings of eBPF and discuss its unique architecture and eBPF program lifecycle. And we will showcase the BCC and libbpf libraries with a live demo "hello-world" example, showing the different stages of the eBPF lifecycle.
