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 ...

This article presents a cracker idea—the kernel module exploit—and shows how you can improve your system's security by using some of the same ideas and techniques. First, I will discuss the origin of ...

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.

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 ...

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.

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 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 ...
