Our objective in this chapter is to introduce the basics of Linux device drivers. We’ll begin with the concept of installable kernel modules. Then we’ll look at the basic device driver APIs in the ...

This approach would allow different security models to work without modifying the main kernel code. Out of this discussion grew the Linux Security Module Project (LSM). A number of developers worked ...

With this second excerpt, Abbott discusses kernel modules and device drivers in Part 1, Part 2, Part 3, Part 4, Part 5 and Part 6. In this final installment of the excerpt, Abbott continues this ...

The kernel, however, including modules, has no such restriction. That can make debugging modules tricky because you can easily bring the system to its knees.

When you program in the kernel, there is no operating system to step in and safely stop your code from running and tell you that you have a problem. The Linux kernel is pretty nice to its own code.

The Linux kernel is a monolithic kernel. It’s mainly one large program, but it closely interacts with other, distinct, programs such as drivers and kernel modules.

The makers of systems programming language Rust are looking at how to adapt the language for use in the Linux kernel. Josh Triplett, a former Intel engineer and a lead of the Rust language team ...

Remote code execution flaw patched in Linux Kernel TIPC module The bug was spotted within a year of introduction to the codebase.

More and more Rust drivers are being added to the Linux kernel. While Rust code represents just 0.1% of the total codebase, that’s still 143 separate files across all facets of the kernel.
