This talk presents an overview of the Linux kernel's eBPF subsystem and how itintegrates into tc (traffic control) and XDP (eXpress Data Path) for providinga high-performance, in-kernel programmable networking data plane. Since thelast fosdem, many new eBPF-related features found its way into the Linuxkernel. This talk highlights some of the most important advances along withsome examples on how this facility can be programmed.
