Here is an example of ANSI C code that will generally cause a segmentation fault on platforms with memory protection. It attempts to modify a string literal, which is undefined behavior according to the ANSI C standard. Most compilers will not catch this at compile time, and instead compile this to executable code that will crash:
Kernel build is the process of compiling and configuring the Linux kernel source code to generate a functional kernel image that can be loaded into memory and executed by the operating system. [1] The kernel serves as the core component of the Linux operating system, providing essential functions such as process management , memory management ...
The Linux kernel and GNU C Library together form the Linux API. After compilation, the binaries offer an ABI . The glibc project was initially written mostly by Roland McGrath, working for the Free Software Foundation (FSF) in the summer of 1987 as a teenager.
NX memory protection has always been available in Ubuntu for any systems that had the hardware to support it and ran the 64-bit kernel or the 32-bit server kernel. The 32-bit PAE desktop kernel (linux-image-generic-pae) in Ubuntu 9.10 and later, also provides the PAE mode needed for hardware with the NX CPU feature.

krf is an open source Linux kernel module which provides a configurable facility to probabilistically return failure values for system calls. nlfaultinjection is designed to provide a simple, portable fault injection framework capable of running on just about any system, no matter how constrained and depends only on the C Standard Library.
PREEMPT_RT was a set of patches for the Linux kernel which implement both hard and soft real-time computing capabilities. [1] On September 20, 2024, PREEMPT_RT was fully merged and enabled in mainline Linux on the supported architectures x86, x86_64, RISC-V and ARM64. [2] This will make kernel v6.12 the first release to include baked-in real ...
Buildroot is a set of Makefiles and patches that simplifies and automates the process of building a complete and bootable Linux environment for an embedded system, while using cross-compilation to allow building for multiple target platforms on a single Linux-based development system.
