This project provides the building blocks for linux netlink. Please see RFC359 and netlink(7)-manpage.

My motivation for creating this library was that I could not find one that had the following properties:

Does not directly depend on the unsafe package and the deprecated syscall package.
Allows users to explicitly set the endian order.

The netlink package provides some serializers, constructors and other parsers for handling netlink messages.
The sock_diag package has serializers and request constructors for the netlink family, NETLINK_SOCK_DIAG. Please see sock_diag.

In the playground directory, you can find different examples on how these packages are used.
