Low-Level Bi-Abduction (Artifact)

Authors: Lukáš Holík, Petr Peringer, Adam Rogalewicz, Veronika Šoková, Tomáš Vojnar, and Florian Zuleger

Published in: DARTS, Volume 8, Issue 2, Special Issue of the 36th European Conference on Object-Oriented Programming (ECOOP 2022)

Abstract
Broom is a new static analyzer for C written in OCaml. Broom primarily aims at open programs, i.e., fragments of programs, with dynamic pointer-linked data structures - in particular, various kinds of lists - that employ advanced low-level pointer operations. It is based on separation logic and the principle of bi-abductive reasoning. The artifact is a VirtualBox image of a Linux machine with Ubuntu 20.04 operating system. It contains source code and binary of the Broom tool, benchmarks, and scripts for running our and the competing tools we compare to.

Low-Level Bi-Abduction

Authors: Lukáš Holík, Petr Peringer, Adam Rogalewicz, Veronika Šoková, Tomáš Vojnar, and Florian Zuleger

Published in: LIPIcs, Volume 222, 36th European Conference on Object-Oriented Programming (ECOOP 2022)

Abstract
The paper proposes a new static analysis designed to handle open programs, i.e., fragments of programs, with dynamic pointer-linked data structures - in particular, various kinds of lists - that employ advanced low-level pointer operations. The goal is to allow such programs be analysed without a need of writing analysis harnesses that would first initialise the structures being handled. The approach builds on a special flavour of separation logic and the approach of bi-abduction. The code of interest is analyzed along the call tree, starting from its leaves, with each function analysed just once without any call context, leading to a set of contracts summarizing the behaviour of the analysed functions. In order to handle the considered programs, methods of abduction existing in the literature are significantly modified and extended in the paper. The proposed approach has been implemented in a tool prototype and successfully evaluated on not large but complex programs.

Summaries for Context-Free Games

Authors: Lukás Holík, Roland Meyer, and Sebastian Muskalla

Published in: LIPIcs, Volume 65, 36th IARCS Annual Conference on Foundations of Software Technology and Theoretical Computer Science (FSTTCS 2016)

Abstract
We study two-player games played on the infinite graph of sentential forms induced by a context-free grammar (that comes with an ownership partitioning of the non-terminals). The winning condition is inclusion of the derived terminal word in the language of a finite automaton. Our contribution is a new algorithm to decide the winning player and to compute her strategy. It is based on a novel representation of all plays starting in a non-terminal. The representation uses the domain of Boolean formulas over the transition monoid of the target automaton. The elements of the monoid are essentially procedure summaries, and our approach can be seen as the first summary-based algorithm for the synthesis of recursive programs. We show that our algorithm has optimal (doubly exponential) time complexity, that it is compatible with recent antichain optimizations, and that it admits a lazy evaluation strategy. Our preliminary experiments indeed show encouraging results, indicating a speed up of three orders of magnitude over a competitor.

View Abstraction – A Tutorial (Invited Paper)

Authors: Parosh A. Abdulla, Fréderic Haziza, and Lukáš Holík

Published in: OASIcs, Volume 44, 2nd International Workshop on Synthesis of Complex Parameters (SynCoP'15) (2015)

Abstract
We consider parameterized verification, i.e., proving correctness of a system with an unbounded number of processes. We describe the method of view abstraction whose aim is to provide a small model property, i.e., showing correctness by only inspecting instances of the system consisting of a small fixed number of processes. We illustrate the method through an application to the classical Burns' mutual exclusion protocol.
