BPF DocumentationΒΆ
This directory contains documentation for the BPF (Berkeley Packet Filter) facility, with a focus on the extended BPF version (eBPF).
This kernel side documentation is still work in progress. The Cilium project also maintains a BPF and XDP Reference Guide that goes into great technical depth about the BPF Architecture.
