This repository contains an example of how to use the Generic Netlink communication protocol of the Linux Kernel both in kernel space and user space.
For more information read my introductory article here; or if you are the adventurous kind just read the source, it's got plenty of comments :)
In order to build the kernel module you need to have installed the Linux kernel headers in your system.
Once you've got the requirements covered just switch to the ks/ directory and
make it.
If the build completed successfully, you should be able to load the
genltest.ko module using insmod.
In order to build the program you need to have libnl installed.
Once installed just switch to the us/ directory and make it.
If the build completed successfully, and once you have loaded the aforementioned
genltest.ko module, you should be able to run the program ./genltest.
