   Abstract

   CPAchecker is a versatile framework for software verification, rooted in the established concept of configurable program analysis. Compared to the last published system description at SV-COMP 2015, the CPAchecker submission to SV-COMP 2024 incorporates new analyses for reachability safety, memory safety, termination, overflows, and data races. To combine forces of the available analyses in CPAchecker and cover the full spectrum of the diverse program characteristics and specifications in the competition, we use strategy selection to predict a sequential portfolio of analyses that is suitable for a given verification task. The prediction is guided by a set of carefully picked program features. The sequential portfolios are composed based on expert knowledge and consist of bit-precise analyses using k-induction, data-flow analysis, SMT solving, Craig interpolation, lazy abstraction, and block-abstraction memoization. The synergy of various algorithms in CPAchecker enables support for all properties and categories of C programs in SV-COMP 2024 and contributes to its success in many categories. CPAchecker also generates verification witnesses in the new YAML format.

   Abstract

   Validation of correctness proofs is an established procedure in software verification. While there are steady advances when it comes to verification of more and more complex software systems, it becomes increasingly hard to determine which information is actually useful for validation of the correctness proof. Usually, the central piece that verifiers struggle to come up with are good loop invariants. While a proof using inductive invariants is easy to validate, not all invariants used by verifiers necessarily are inductive. In order to alleviate this problem, we propose LIV, an approach that makes it easy to check if the invariant information provided by the verifier is sufficient to establish an inductive proof. This is done by emulating a Hoare-style proof, splitting the program into Hoare triples and converting these into verification tasks that can themselves be efficiently verified by an off-the-shelf verifier. In case the validation fails, useful information about the failure reason can be extracted from the overview of which triples could be established and which were refuted. We show that our approach works by evaluating it on a state-of-the-art benchmark set.

   Abstract

   Abstraction is a key technology for proving the correctness of computer programs. There are many approaches available, but unfortunately, the various techniques are difficult to combine and the successful techniques have to be re-implemented again and again.
   We address this problem by using the tool CEGAR-PT, which views abstraction as program transformation and integrates different verification components off-the-shelf. The idea is to use existing components without having to change their implementation, while still adjusting the precision of the abstraction using the successful CEGAR approach. The approach is largely general: it only restricts the abstraction to transform, given a precision that defines the level of abstraction, one program into another program. The abstraction by program transformation can over-approximate the data flow (e.g., havoc some variables, use more abstract types) or the control flow (e.g., loop abstraction, slicing).
