Operating System Verification

Operating System Verification — An Overview

This paper gives a high-level introduction to the topic of formal, interactive, machine-checked software verification in general, and the verification of operating systems code in particular. We survey the state of the art, the advantages and limitations of machinechecked code proofs, and describe two specific ongoing larger-scale verification projects in more detail.

Operating System Verification for Real Use

Software verification remains an academic exercise as long as it focusses on toy problems, such as systems that are too simplified for practical deployment, or perform too poorly. Furthermore, formal verification of software is of limited benefit if the software is deployed in a system where it executes on top of an unverified operating system. This talk presents an overview of an effort at NIC...

Kernel Aware Module Verification for Robust Reconfigurable Operating System

The loadable kernel modules supported by Linux provide many benefits including a small-sized kernel, on-demand loading, and simpler upgrading of software. However, modules are executed in a privileged mode so that trivial errors in a module may cause a critical system halt or deadlock situations. We introduce a kernel resource protector which shields the kernel from faults generated by modules....

Distributed Application Operating System Operating System Api

Middleware is a class of software technologies designed to help manage the complexity and heterogeneity inherent in distributed systems. It is defined as a layer of software above the operating system but below the application program that provides a common programming abstraction across a distributed system, as shown in Figure 1. In doing so, it provides a higher-level building block for progr...
