I always forget howto run the BPF selftests. Thus, lets add that info to the QA document. Documentation was based on Cilium's documentation: http://cilium.readthedocs.io/en/latest/bpf/#verifying-the-setup Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

================= BPF documentation ================= 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 main textual documentation is (for historical reasons) described in `Documentation/networking/filter.txt`_, which describe both classical and extended BPF instruction-set. The Cilium project also maintains a `BPF and XDP Reference Guide`_ that goes into great technical depth about the BPF Architecture. The primary info for the bpf syscall is available in the `man-pages`_ for `bpf(2)`_. Frequently asked questions (FAQ) ================================ Two sets of Questions and Answers (Q&A) are maintained. * QA for common questions about BPF see: bpf_design_QA_ * QA for developers interacting with BPF subsystem: bpf_devel_QA_ ..
