High Confidence Operating Systems

Operating System development is difficult; debugging OSs is a daunting challenge, especially considering the hostile kernel environment and the amount of concurrency that takes place. A stable OS is crucial, especially in light of today's attackers who are looking for any way to exploit bugs to gain unauthorized access. In this project we apply formal verification techniques, using Concurrent Class Machines (CCMs) to verify that kernel code confirms to system call specifications. We verify that no sequence of system calls, with any input, could potentially leave the OS in an inconsistent state or crash the OS. We explore static techniques at compile time, dynamic techniques at run time, slicing as a way to focus on specific aspects of the kernel code (e.g., locking semantics, reference counting consistency, etc.).
