A “better” Makefile template for your kernel modules

The preceding chapter introduced you to the Makefile used to generate the kernel module from the source code, to install and clean it up. However, as we briefly mentioned there, I will now introduce what is, in my opinion, a superior, so-called “better” Makefile, and explain how it’s better.

Ultimately, we all must write better and more secure code – both user- and kernel-space. The good news is that there are several tools to help improve your code’s robustness and security posture, static and dynamic analyzers being among them (as several have already been mentioned in Online Chapter, Kernel Workspace Setup, I won’t repeat them here).

I have devised a simple yet useful Makefile “template” of sorts for kernel modules that includes several targets that help you run these tools. These targets allow you to perform valuable checks and analysis very easily...
