BPF Tokens in systemd (asg2025)

Chaos Computer Club - recent events feed

Running **BPF** programs today requires *CAP_BPF* capability, which is an all or nothing BPF capability. But BPF nowadays spans a large area, from simple monitoring to potentially invasive fields like network or tracing. BPF Tokens aims to add fine grained BPF capabilities to systemd units and containers, avoiding to give the whole *CAP_BPF* capability or even worse running the service as privileged user.
