   Abstract

   Many of the current verification approaches can be classified into automatic and interactive techniques, each having different strengths and weaknesses. Thus, one of the current open problems is to design solutions to combine the two approaches and accelerate technology transfer. We outline four existing techniques that might be able to contribute to combination solutions: (1) Conditional model checking is a technique that gives detailed information (in form of a condition) about the verified state space, i.e., informs the user (or tools later in a tool chain) of the outcome. Also, it accepts as input detailed information (again as condition) about what the conditional model checker has to do. (2) Correctness witnesses, stored in a machine-readable exchange format, contain (partial) invariants that can be used to prove the correctness of a system. For example, tools that usually expect invariants from the user can read the invariants from such correctness witnesses and ask the user only for the remaining invariants. (3) Abstraction-refinement based approaches that use a dynamically adjustable precision (such as in lazy CEGAR approaches) can be provided with invariants from the user or from other tools, e.g., from deductive methods. This way, the approach can succeed in constructing a proof even if it was not able to come up with the required invariant. (4) The technique of path invariants extracts (in a CEGAR method) a path program that represents an interesting part of the program for which an invariant is needed. Such a path program can be given to an expensive (or interactive) method for computing invariants that can then be fed back to a CEGAR method to continue verifying the large program. While the existing techniques originate from software verification, we believe that the new combination ideas are useful for verifying general systems.

   Abstract

   Symbolic execution, a standard technique in program analysis, is a particularly successful and popular component in systems for test-case generation. One of the open research problems is that the approach suffers from the path-explosion problem. We apply abstraction to symbolic execution, and refine the abstract model using counterexampleguided abstraction refinement (CEGAR), a standard technique from model checking. We also use refinement selection with existing and new heuristics to influence the behavior and further improve the performance of our refinement procedure. We implemented our new technique in the open-source software-verification framework CPAchecker. Our experimental results show that the implementation is highly competitive.

    Abstract

    We present local policy iteration (LPI), a new algorithm for deriving numerical invariants that combines the precision of max-policy iteration with the flexibility and scalability of conventional Kleene iterations. It is defined in the Configurable Program Analysis (CPA) framework, thus allowing inter-analysis communication. LPI uses adjustable-block encoding in order to traverse loop-free program sections, possibly containing branching, without introducing extra abstraction. Our technique operates over any template linear constraint domain, including the interval and octagon domains; templates can also be derived from the program source. The implementation is evaluated on a set of benchmarks from the International Competition on Software Verification (SV-COMP). It competes favorably with state-of-the-art analyzers.
