The following excerpt is from chapter 3, User-Level Memory Management, of Arnold Robbins’ book Linux Programming by Example: The Fundamentals, Prentice Hall PTR; (April 12, 2004), used with permission ...

The Linux kernel Out of Memory (OOM) killer is not usually invoked on desktop and server computers, because those environments contain sufficient resident memory and swap space, making the OOM ...

Linux processes are made up of text, data, and BSS static segments; in addition, each process has its own stack (which is created with the fork system call). Heap space for Linux tasks are allocated ...

This week, ZDNet’s Steven J. Vaughan-Nichols asked Linus Torvalds and Greg Kroah-Hartman about the possibility of new Linux kernel code being written in Rust—a high performance but memory-safe ...

One of the problems with developing embedded systems is the detection of memory leaks; I've found three tools that are useful for this. These tools are used to detect application program errors, not ...

As a programmer, I’m aware that I tend to make mistakes — and why not? Even programmers are human. Some errors are detected during code compilation, while others ...

Several commands report on how much memory is installed and being used on Linux systems. You can be deluged with details or get a quick and easy answer, depending on ...

When selecting the optimal OS for an embedded systems project it is important to compare the available options – will RTOS or Linux serve best? asks Graeme Wintle. At a top level, the choice is ...

Android 15’s new Linux Terminal app is limited to 4GB of memory, which can be insufficient for developers. A workaround involves increasing the zram size, creating a swap file, and adjusting ...

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 ...
