^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) This directory contains documentation for the BPF (Berkeley Packet
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) Filter) facility, with a focus on the extended BPF version (eBPF).

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) This kernel side documentation is still work in progress. The main
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) textual documentation is (for historical reasons) described in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) :ref:`networking-filter`, which describe both classical and extended
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) BPF instruction-set.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) The Cilium project also maintains a `BPF and XDP Reference Guide`_
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) that goes into great technical depth about the BPF Architecture.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) The primary info for the bpf syscall is available in the `man-pages`_
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) for `bpf(2)`_.
