Debugging the BPF Virtual Machine Lorenzo Fontana October 28, 2020 ● Debugging is useful to understand how things work ● Sometimes, eBPF programs can’t even load ● I couldn’t find good resources on this this, so, here I am ● I break lots of eBPF programs ● The BPF Virtual machine is not easy to understand Why ? The BPF subsystem lives in the kernel AND The kernel can be debugged using gdb The

program. The Live Server installer uses a text-based console interface which runs on the default virtual console. The interface can be entirely driven by the enter, up and down arrow keys (with some occasional options. • Download the appropriate ISO file from the Ubuntu web site4. • Boot the system from media (e.g. USB key) containing the ISO file. • At the boot prompt you will be asked to select a language options to install Ubuntu Server Edition. You can install a basic Ubuntu Server, check the installation media for defects, check the system's RAM, or boot from first hard disk. The rest of this section will cover
