Package netlink provides low-level access to Linux netlink sockets
(AF_NETLINK). MIT Licensed.
For more information about how netlink works, check out my blog series on Linux, Netlink, and Go.

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.
This package only supports the two most recent major versions of Go, mirroring Go's own release policy. Older versions of Go may lack critical features and bug fixes which are necessary for this package to function correctly.
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.
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.
