Extended BPF (or 64-bit BPF) is an instruction set to create safe dynamically loadable filters that can call fixed set of kernel functions and take generic bpf_context as an input. BPF filter is a glue between kernel functions and bpf_context. Different kernel subsystems can define their own set of
