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.

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 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.

Programmers had already been experimenting with earlier versions of the language as an option for kernel module programming, with a proof of concept developed in 2013.

Hi folks - I've found myself having do some socket programming in the linux kernel. (yes, yes, I know: have I thought about user space? Yes, that's where I've prototyped my code. This is a ...

What superpowers? eBPF gives you the power to run programs in the Linux kernel without changing the kernel source code or adding additional modules. In effect, it acts as a lightweight (VM) inside ...

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 ...

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.

The memory safe programming language will join C and the other traditional languages developers use to create new pieces and drivers of the ubiquitous open source kernel.

In this second excerpt, Abbott discusses kernel modules and device drivers. In Part 1 of this excerpt the author worked through an example of a simple kernel module. In this installment, Abbott ...
