When you write programs in user space, the worst thing that can happen to your program is a core dump. Your program did something very wrong, so the operating system decided to give you all of its ...

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.

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.

Editor's Note: Linux remains an attractive option for embedded systems developers. In fact, industry surveys such as the Embedded Market Study by UBM (EDN's parent company) consistently show interest ...

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 ...

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.
