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)`_.
