Stability

See the CHANGELOG file for a description of changes between releases.

This package has a stable v1 API and any future breaking changes will prompt the release of a new major version. Features and bug fixes will continue to occur in the v1.x.x series.

The general policy of this package is to only support the latest, stable version of Go. Compatibility shims may be added for prior versions of Go on an as-needed basis. If you would like to raise a concern, please file an issue.

If you depend on this package in your applications, please use Go modules.

Design

A number of netlink packages are already available for Go, but I wasn't able to find one that aligned with what I wanted in a netlink package:

  • Straightforward, idiomatic API
  • Well tested
  • Well documented
  • Doesn't use package/global variables or state
  • Doesn't necessarily need root to work

My goal for this package is to use it as a building block for the creation of other netlink family packages.

Ecosystem

Over time, an ecosystem of Go packages has developed around package

netlink
. Many of these packages provide building blocks for further interactions with various netlink families, such as
NETLINK_GENERIC
or
NETLINK_ROUTE
.

To have your package included in this diagram, please send a pull request!
