Kernel Mode Linux (KML) is a technology that enables the execution of user processes in kernel mode. I described the basic concept and the implementation techniques of KML on IA-32 architecture in my ...

After years of countless reviews, discussions, and code rewrites, Linus Torvalds approved on Saturday a new security feature for the Linux kernel, named "lockdown." The new feature will ship as a LSM ...

In particular, memory areas used as input and/or output are isolated from the rest of the kernel and surrounded by guard pages. Without arch hooks, this common base provides weak isolation. On ...

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 course provides an introduction to Kernel programming for the Linux operating system, and the development of Linux kernel drivers for Embedded devices. The Yocto build system is introduced, which ...

Wine 11.0, the latest stable release of the open-source compatibility layer that allows Windows games and apps to run on Linux and macOS, has been ...

Blacklisting modules prevents them from being loaded and used, and it is sometimes an important step in keeping a system running properly. The Linux kernel is modular — composed of modules that work ...

A novel Linux Kernel cross-cache attack named SLUBStick has a 99% success in converting a limited heap vulnerability into an arbitrary memory read-and-write capability, letting the researchers elevate ...

The Linux kernel provides support for memory management, interprocess communication mechanisms, interrupt management, and TCP / IP networking. The directory structure separates architecture-dependent ...
