eBPF Hookpoint Gotchas: Why Your Program Fires (or Fails) in Unexpected Ways
<p>eBPF programs often behave differently than developers expect, not because of incorrect logic, but because of subtle behaviours of the hookpoints themselves. In this talk, we focus on a small set of high-impact, commonly misunderstood attachment types — kprobes/fentry, tracepoints and uprobes, and expose the internal kernel mechanics that cause surprising edge cases.</p>
<p>Rather than attempting to cover all eBPF hooks, this session distills a practical set of real-world gotchas that routinely affect production tools, explaining why they occur and how to work around them.</p>
