Demystifying TCP Packets: The EBPF Approach

Sep 30, 2024 · by leveraging ebpf and xdp, we can capture tcp header information directly within the kernel, minimizing overhead and improving performance. In this tutorial, we’ll. In this paper, we demonstrate how to leverage the ebpf virtual machine that is part of the recent versions of the linux kernel to make the tcp stack easier to extend. Ebpf allows reprogramming the behavior of the linux kernel without changing the kernel source code or writing kernel modules. Prior flow experience is aggregated.
