Introduction

If you're reading this, chances are you have some idea of eBPF and XDP. In this article, we'll write an eBPF program that will count and categorize packets based on the destination port.

eBPF

Writing low-level tracing, monitoring, or network programs in Linux is not easy. Through all the layers of the kernel, people have been squeezing every bit of performance they could get.

And that's where eBPF comes in. eBPF is basically an extended and modern variation of BPF which is like a virtual machine inside the Linux kernel. It can execute user-defined programs inside a sandbox in the kernel.

These programs can be executed in various hook points but we will focus on XDP for now.

Arch Linux Root on ZFS

Installation steps for running Arch Linux with root on ZFS using UEFI and systemd-boot. All steps are run as root.

Requires an Arch Linux image with ZFS built-in (see References).

In live environment

If using KVM, add a Serial number for each virtual disk and reboot the VM. The disks should now be available in /dev/disk/by-id as virtio-<Serial>.
