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.

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.

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 ...

In our previous installment, the author introduced methods for accessing peripherals from user space in Linux. In this installment, Abbott describes kernel modules and device drivers followed by a ...

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 ...

Step by step, the Rust programming language is moving deeper into the Linux kernel.

This course provides an overview of System Programming for the Linux operating system, or software which is interfacing directly with the Linux Kernel and C library. The basic components of a Linux ...

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.
