We port verification techniques for device drivers from the Windows domain to Linux, combining several tools and techniques into one integrated tool-chain. Building on ideas from Microsoft’s
Static Driver Verifier
(SDV) project, we extend their specification language and combine its implementation with the public domain bounded model checker CBMC as a new verification back-end. We extract several API conformance rules from Linux documentation and formulate them in the extended language SLICx. Thus SDV-style verification of temporal safety specifications is brought into the public domain. In addition, we show that SLICx, together with CBMC, can be used to simulate preemption in multi-threaded code, and to find race conditions and to prove the absence of deadlocks and memory leaks.
