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.

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 ...

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 ...

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 ...

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.

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 ...
