The extensions in eBPF, the extended Berkley Packet Filter, transformed BPF into a powerful in-kernel virtual machine and ultimately allowed eBPF programs to be attached to many parts of the kernel, many of which have nothing to do with network packets!

In this session Daniel will review the low-level mechanisms that allow developers to gather information for debug and tuning by attaching eBPF programs to probe and tracepoints. Daniel will follow up by dissecting a roll-your-own example program to illustrate how userspace exploits these mechanisms.

After that we move from theory to practice by looking at several userspace tools that allow developers to write high level eBPF programs (or run other peoples pre-canned ones) and process the resulting data.
