Mostly-automated verification of low-level programs in computational separation logic

Abstract

Several recent projects have shown the feasibility of verifying low-level systems software. Verifications based on automated theorem-proving have omitted reasoning about first-class code pointers, which is critical for tasks like certifying implementations of threads and processes. Conversely, verifications that deal with first-class code pointers have featured long, complex, manual proofs. In this paper, we introduce the Bedrock framework, which supports mostly-automated proofs about programs with the full range of features needed to implement, e.g., language runtime systems.
