Automated Formal Verification of Software Network Functions

Formally verifying the correctness of software is necessary to merit the trust people put in software systems. Currently, formal verification requires human effort to prove that a piece of code matches its specification and code changes to improve verifiab ...

WarpAttack: Bypassing CFI through Compiler-Introduced Double-Fetches

Mathias Josef Payer, Flavio Toffalini, Luca Di Bartolomeo, Jianhao Xu

Code-reuse attacks are dangerous threats that attracted the attention of the security community for years. These attacks aim at corrupting important control-flow transfers for taking control of a process without injecting code. Nowadays, the combinations o ...

Scalable Metaprogramming in Scala 3

Nicolas Alexander Stucki

A metaprogrammer should be able to reason about the semantics of the generated code. Multi-stage programming introduced an elegant and powerful solution to this problem. It follows a semantically driven approach to code generation, where semantics are full ...

ACTOR: Action-Guided Kernel Fuzzing

Mathias Josef Payer

Fuzzing reliably and efficiently finds bugs in software, including operating system kernels. In general, higher code coverage leads to the discovery of more bugs. This is why most existing kernel fuzzers adopt strategies to generate a series of inputs that ...

Scaling Functional Synthesis and Repair

Emmanouil Koukoutos

Program synthesis was first proposed a few decades ago, but in the last decade it has gained increased momentum in the research community. The increasing complexity of software has dictated the urgent need for improved supporting tools that verify the soft ...

Code Generation in Computational Neuroscience: A Review of Tools and Techniques

Michael Lee Hines, Pramod Shivaji Kumbhar, Romain Brette

Advances in experimental techniques and computational power allowing researchers to gather anatomical and electrophysiological data at unprecedented levels of detail have fostered the development of increasingly complex models in computational neuroscience ...

Interactive Synthesis using Free-Form Queries

Viktor Kuncak, Tihomir Gvero

We present a new code assistance tool for integrated development environments. Our system accepts free-form queries allowing a mixture of English and Java as an input, and produces Java code fragments that take the query into account and respect syntax, ty ...

-Overify: Optimizing Programs for Fast Verification

George Candea, Volodymyr Kuznetsov, Jonas Benedict Wagner

Developers rely on automated testing and verification tools to gain confidence in their software. The input to such tools is often generated by compilers that have been designed to generate code that runs fast, not code that can be verified easily and quic ...

Towards Static Analysis of Virtualization-Obfuscated Binaries

Johannes Kinder

Virtualization-obfuscation protects a program from manual or automated analysis by compiling it into bytecode for a randomized virtual architecture and attaching a corresponding interpreter. Static analysis appears to be helpless on such programs, where on ...

Alternating Control Flow Reconstruction

Johannes Kinder

Unresolved indirect branch instructions are a major obstacle for statically reconstructing a control flow graph (CFG) from machine code. If static analysis cannot compute a precise set of possible targets for a branch, the necessary conservative over-appro ...

Is non-unique decoding necessary?

Suhas Diggavi, Vinod Malathidevi Prabhakaran, Shirin Saeedi Bidokhti

In multi-terminal communication systems, signals carrying messages meant for different destinations are often observed together at any given destination receiver. Han and Kobayashi (1981) proposed a receiving strategy which performs a joint unique decoding ...

Lightweight Modular Staging: A Pragmatic Approach to Runtime Code Generation and Compiled DSLs

Martin Odersky, Tiark Rompf

Good software engineering practice demands generalization and abstraction, whereas high performance demands specialization and concretization. These goals are at odds, and compilers can only rarely translate expressive high-level programs to modern hardwar ...

Lightweight Modular Staging and Embedded Compilers : Abstraction without Regret for High-Level High-Performance Programming

Tiark Rompf

Programs expressed in a high-level programming language need to be translated to a low-level machine dialect for execution. This translation is usually accomplished by a compiler, which is able to translate any legal program to equivalent low-level code. B ...

Parallel symbolic execution for automated real-world software testing

George Candea, Cristian Zamfir, Stefan Bucur, Vlad Ureche

This paper introduces Cloud9, a platform for automated testing of real-world software. Our main contribution is the scalable parallelization of symbolic execution on clusters of commodity hardware, to help cope with path explosion. Cloud9 provides a system ...

Flexible and Efficient Measurement of Dynamic Bytecode Metrics

Code instrumentation is finding more and more practical applications, but the required program transformations are often difficult to implement, due to the lack of dedicated, high-level tools. In this paper we present a novel instrumentation framework that ...

RoclET– Refactoring OCL Expressions by Transformations

Slavisa Markovic, Cédric Jeanneret, Leander Eyer

The role of UML models in software development has changed considerably over the last years. While UML was used in its early days mostly as a notation for sketching ideas, developers more and more recognize now the value of a UML model as a formal document ...

Generation of object-oriented programs from CO-OPN specifications

Stanislav Chachkov

The execution of formal specifications is important for verification, validation and animation purposes. This thesis describes transformation of CO-OPN specifications in executable code. The original goal of this transformation was validation by prototypin ...
