eBPF Challenge for Beginners
In this challenge, you’ll debug and fix a deliberately “broken” eBPF program, then prove it’s running by identifying its program and map IDs. Along the way, you’ll explore bpftool, check which helpers are supported, and dig into details like the UID of the loader. Finally, you’ll test your knowledge of eBPF maps by recalling the flag that only inserts a key if it doesn’t already exist.
