Partially Separated Page Tables for Efficient Operating System Assisted Hierarchical Memory Management on Heterogeneous Architectures

In today’s mobile computing, Linux plays a significant role. The Linux kernel has been adopted by a variety of mobile operating systems to handle tasks such as device management, memory management, process management, networking, power management, application interface management, and user interface management. This chapter introduces Linux based mobile operating systems installed on various mobile devices. It first gives a brief introduction of the history of mobile Linux. Then, the chapter introduces the mobile Linux features that can be used to meet the mobile learning requirements. The last part of the chapter presents strategies on selecting a Linux based operating system for a particular mobile learning project.

Address Space Layout Randomization

Memory management is one of the main tasks of an Operating System, where the data of each process running in the system is kept. In this context, there exist several types of attacks that exploit memory-related vulnerabilities, forcing Operating Systems to feature memory protection techniques that make difficult to exploit them. One of these techniques is ASLR, whose function is to introduce randomness into the virtual address space of a process. The goal of this work was to measure, analyze and compare the behavior of ASLR on the 64-bit versions of Windows 10 and Ubuntu 18.04 LTS. The results have shown that the implementation of ASLR has improved significantly on these two Operating Systems compared to previous versions. However, there are aspects, such as partial correlations or a frequency distribution that is not always uniform, so it can still be improved.

Replacement Algorithms

The concept of Super-Paging has been wandering around for more than a decade. Super-Pages are supported by some operating systems. In addition, there are some interesting research papers that show interesting ideas how to intelligently integrate Super-Pages into modern operating systems; however, the page replacement algorithms used by the contemporary operating system even now use the old Clock algorithm which does not prioritize small or large pages based on their size. In this chapter an algorithm for page replacement in a Super-Page environment is presented. The new technique for page replacement decisions is based on the page size and other parameters; hence is appropriate for a Super-Paging environment.
