Unfortunately for kernel developers, allocating memory in the kernel is not as simple as allocating memory in user space. A number of factors contribute to the complication, among them: The kernel is ...
If your production Linux system is logging memory allocation failures, it might still be able to keep running. But developers want to keep an eye on which code can survive a shortage of memory. In ...
Researchers from the Graz University of Technology have discovered a way to convert a limited heap vulnerability in the Linux kernel into a malicious memory writes capability to demonstrate novel ...
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 ...
In a previous article [“An Event Mechanism for Linux”, LJ, July 2003], we introduced the necessity for Linux to adopt a native and generic event mechanism in the context of telecom. Many existing ...
