| H A D | intro.rst | 4 Introduction to Netlink
7 Netlink is often described as an ioctl() replacement.
12 To achieve this Netlink uses a minimal fixed-format metadata header
18 netlink as it is used today and dives into more "historical" uses
24 Netlink communication happens over sockets, a socket needs to be
36 A very simplified flow of a Netlink "call" will therefore look
48 Netlink also provides natural support for "dumping", i.e. communicating
70 it is opening a Netlink socket, with all headers provided by the user
71 (hence NETLINK, RAW). The last argument is the protocol within Netlink.

| H A D | specs.rst | 4 Netlink protocol specifications (in YAML)
7 Netlink protocol specifications are complete, machine readable descriptions of
8 Netlink protocols written in YAML. The goal of the specifications is to allow
9 separating Netlink parsing from user space logic and minimize the amount of
10 hand written Netlink code for each new family, command, attribute.
11 Netlink specs should be complete and not depend on any other spec
22 YAML specifications can be found under ``Documentation/netlink/specs/``
34 There are four schema levels for Netlink specs, from the simplest used
45 - ``genetlink-legacy`` - Generic Netlink catch all schema supporting quirks of
47 - ``netlink-raw`` - catch all schema supporting pre-Generic Netlink protocols

7 This document describes the additional properties required by raw Netlink
8 families such as ``NETLINK_ROUTE`` which use the ``netlink-raw`` protocol

7 This document is a quick starting guide for using Netlink protocol
14 developing Netlink related code. The tool is implemented in Python
15 and can use a YAML specification to issue Netlink requests
16 to the kernel. Only Generic Netlink is supported.
26 YAML specs can be found under ``Documentation/netlink/specs/``.
