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 ...

Although Linux does not (yet) support this binary format, the good news is that you can learn how to write kernel modules by implementing COM support for the Linux kernel.

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 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.

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.

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.

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 ...

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.

Members of the open source community are working on a new security-focused project for the Linux kernel. Named Linux Kernel Runtime Guard (LKRG), this is a loadable kernel module that will perform ...
