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

The interface can be entirely driven by the enter, up and down arrow keys (with some occasional There are three options: • No automatic updates: this requires an administrator to log into the machine and manually install updates. • Install security updates automatically: this will install the unattended-upgrades Tomcat Java server: Installs Apache Tomcat and needed dependencies. • Virtual Machine host: Includes packages needed to run KVM virtual machines. • Manually select packages: Executes aptitude allowing you
