Goanna—A Static Model Checker Ansgar Fehnker1,Ralf Huuck1,Patrick Jayet2 ,Michel Lussenburg2∗,andFelix Rauch11National ICT Australia Ltd.(NICTA) and University of New South Wales,Locked Bag6016,NSW1466,Australia2Department of Computer Science,Swiss Federal Institute of Technology(ETH),CH-8092Zurich,SwitzerlandAbstract.In this work we present Goanna,thefirst tool that uses anoff-the-shelf model checker for the static analysis of C/C++source code.We outline its architecture and show how syntactic properties can be ex-pressed in CTL.Once the properties have been defined the tool analysessource code automatically and efficiently.We demonstrate its applica-bility by presenting experimental results on analysing OpenSSL and theGNU coreutils.1IntroductionFormal design and analysis techniques are successfully applied to hardware.In fact,model checking parts of the chip design is common practice.However,the application of verification technology to existing and complex software has been much less successful.The reasons are manifold:Full formal verification as done by interactive the-orem proving is expensive.It requires a lot of time and expertise,making it often impractical for software that has a short life cycle,is not highly safety-critical,or suffers from a high pressure to market.Algorithmic verification techniques have to deal with software’s infinite state space,requiring abstraction techniques to make properties of interest decidable.Suitable abstractions are typically hard to compute and the overall interaction required by the user in order to apply them to real-life software are often considerable.One area that has been successful is static analysis[1,2].Approaches such as abstract interpretation,dataflow analysis and other static checking techniques have made it into several industrial strength tools.In this work we present Goanna[3],a static analysis tool for C/C++source code based on model checking.It uses the NuSMV[4]model checker as the underlying verification engine,allows the specification of user defined properties This work was carried out while visiting NICTA.National ICT Australia is funded by the Australian Governments Department of Communications,Information Technology and the Arts and the Australian Research Council through Backing Australias Ability and the ICT Research Centre of Excel-lence programs.and scales well to commercial size software.Since Goanna does not require any user interaction it makes it particularly suited to be integrated into the software development process.Moreover,it is thefirst step of bringing static analysis and software model checking closer together by providing one uniform framework. 2TechnologyThe basic ideas of solving static analysis problems by model checking have been first developed by Steffen and Schmidt[5].While their main focus has been on developing a safe approximation of the program’s behaviour to check for safety properties,we abandon in some cases the soundness of the analysis for effectiveness.This means we can check for full CTL including(syntactic)liveness properties.The CTL model checking problem is encoded in two steps and we illustrate this by a simple example.First we define the atomic propositions of interest we like to reason about,e.g.,whether a variable is declared,used,or assigned a value. For a variable named x we write decl x,used x and assigned x for the respective propositions.We use a pattern matching approach to relate certain patterns on a program’s abstract syntax tree(AST)with propositions of interest.In a second step we automatically extract the controlflow graph(CFG)of a program and label it with the previously determined propositions.Fig.1.Goanna architecture Fig.2.Goanna results in EclipseThe translation of an annotated CFG into a NuSMV model is rather straight-forward and the encoding can be done in an efficient way resulting in a small state space.Properties of interest can then be expressed as CTL formulae over this model.E.g.,checking for uninitialised variables can be expressed as follows:AG decl x⇒(A¬used x W assigned x)This means we require that on all program paths if a variable is declared it must not be used until it has a value assigned or it will not be used at all.Weuse the weak until operator W here to include the second possibility.The latter can also point to unused variables,which is checked separately.Our tool chain is depicted in Figure1.We use gcc as a front end,as one of its features allows us to easily output the AST of C/C++programs in an intermediate language.We parse the AST and on the one hand generate the CFG from it and on the other hand match patterns on the AST,which constitute the atomic propositions of a CTL formula expressing the desired property.We label the CFG with atomic propositions where their respective patterns were matched. Once the patterns and the CTL formula have been specified,the translation of the C/C++source code into a suitable NuSMV model and its checking is fully automatic.The current implementation is developed in OCaml.Goanna is easily inte-grated in Makefiles and,thus,is automatically supported by development envi-ronments such as Eclipse.A screen shot of Goanna running in combination with Eclipse can be found in Figure2.As a result we obtain a seamless integration into the overall software development process.3ApplicationTo evaluate the applicability of our tool,we examine two real-world open-source software packages:The GNU coreutils3,which provide basicfile,shell and text manipulation utilities(59kLoC4),and the OpenSSL5toolkit imple-menting the Secure Sockets Layer(SSL)and Transport Layer Security(TLS) protocols(260kLoC).We analyse the source code of these two packages on a recent3.4GHz Xeon-processor-based server.Analysing the whole source with our current Goanna tool(which has not yet been optimised)takes slightly less than2minutes for the coreutils and slightly less than29minutes for OpenSSL.The latter is somewhat distorted by a single pathologicalfile that takes almost12minutes to analyse.In practice,analysis times are typically much shorter,because the analysis can be done incrementally on the set of recently changedfiles only and a more in-depth study of Goanna’s analysis times shows that a large majority of sourcefiles is analysed quite quickly. In fact,72%of all sourcefiles in the coreutils are analysed in less than1second and95%under5seconds.Similarly,for OpenSSL83%of allfiles are analysed in under1second and again95%under5seconds.Note that the current prototype has not yet been optimised regarding exe-cution time.Hence,there is still a lot of room for performance improvements, for example by optimising the search in the AST for patterns of interest(which currently contains redundant searches for different properties),the OCaml li-brary we use to conduct the search on the AST(which is convenient to use but not efficient),or by changing the way in which we use NuSMV(which is cur-3/software/coreutils/4LoC=Lines of Code,kLoC=1000Lines of Codes5/rently invoked with rather large chunks of source code at the time that could be reduced to smaller pieces).Looking at the memory requirements of our tool wefind that the maximum memory consumption of the analysis is about65MiB to analyse the coreutils and about113MiB for OpenSSL respectively.This is in both cases much below the limit set by todays PCs used by developers.The above numbers show that the tool is already quite usable in practice.A full evaluation of course requires also an analysis of the precision of the tool, with looking at the number of real bugs found and the number of false positives reported.Such a study is very time consuming and we are still in the process of qualitatively evaluating Goanna regarding its precision.Preliminary results indicate that the precision of our approach is comparable to standard static analysis.4ConclusionIn this work we presented Goanna,thefirst static analyser purely based on an off-the-shelf model checker.We demonstrated that the approach scales well to real-life software,making it suitable for the integration into the overall software development process.While Goanna is fast,it is not yet more precise than traditional static analy-sis.However,we anticipate to improve on this by incorporating more semantic-based software model checking techniques such as predicate abstraction[6].The foundation of this integration has been laid by having a uniform framework for static analysis as well as traditional model checking.References1.Engler,D.R.,Musuvathi,M.:Static analysis versus software model checking forbugfinding.In:”VMCAI’04:5th Intl.Conference Verification,Model Checking and Abstract Interpretation”.(2004)191–2102.Blanchet,B.,Cousot,P.,Cousot,R.,Feret,J.,Mauborgne,L.,Min´e;,A.,Monni-aux,D.,Rival,X.:Design and implementation of a special-purpose static program analyzer for safety-critical real-time embedded software.(2002)85–1083.NICTA:The Goanna Project.(.au/research/goanna/)4.Cimatti,A.,Clarke,E.,Giunchiglia,E.,Giunchiglia,F.,Pistore,M.,Roveri,M.,Sebastiani,R.,Tacchella,A.:NuSMV Version2:An OpenSource Tool for Symbolic Model Checking.In:Proc.International Conference on Computer-Aided Verification (CAV2002).Volume2404of LNCS.,Springer(2002)5.Schmidt,D.A.,Steffen,B.:Program analysis as model checking of abstract inter-pretations.In:SAS’98:Proceedings of the5th International Symposium on Static Analysis,London,UK,Springer-Verlag(1998)351–3806.Ball,T.,Cook,B.,Levin,V.,Rajamani,S.K.:SLAM and Static Driver Verifier:Technology transfer of formal methods inside Microsoft.In:IFM2004:4th Interna-tional Conference on Integrated Formal Methods.Volume2999of LNCS.,Springer-Verlag(2004)1–20Below is given annual work summary, do not need friends can download after editor deleted Welcome to visit againXXXX annual work summaryDear every leader, colleagues:Look back end of XXXX, XXXX years of work, have the joy of success in your work, have a collaboration with colleagues, working hard, also have disappointed when encountered difficulties and setbacks.

verifying signed artifacts报错的解决方法-回复Verifying Signed Artifacts: A Step-by-Step Troubleshooting GuideIntroduction:In this article, we will explore the common issues and troubleshooting steps associated with the "verifying signed artifacts" error. Verifying signed artifacts is a crucial process in software development and deployment, ensuring that the digital signature attached to a file or artifact is valid and has not been tampered with. However, sometimes these verifications may fail, leading to errors or unexpected behavior. In this comprehensive guide, we will delve into the potential causes of these errors and outline step-by-step solutions to rectify them.Step 1: Understand the BasicsBefore diving into troubleshooting, it is important to have a clear understanding of the concept of signed artifacts and why verification is essential. Signed artifacts are files that have a digital signature attached to them, intended to prove the authenticity and integrity of the file. The verification process involves checking the signature against a trusted certificate authority (CA) to ensure its validity.Step 2: Identify the Error MessageThe first step in troubleshooting is to identify the exact error message you encounter when trying to verify the signed artifact. This information is crucial as it provides important clues about the root cause of the problem. Common error messages may indicate issues with the certificate, the signing process, or the verification mechanism.Step 3: Check the Certificate ChainOne possible cause of the error is an incomplete or improperly installed certificate chain. Start by checking the certificate chain attached to the signed artifact. Ensure that all intermediate certificates are present and correctly installed on the machine doing the verification. If any of the certificates are missing or expired, obtain the correct certificates from the issuing CA and install them correctly.Step 4: Verify the Certificate Revocation StatusAnother potential issue could be the revocation status of the certificate used to sign the artifact. Certificates can be revoked for various reasons, including compromise, expiration, or a change inthe certificate owner's circumstances. Verify the revocation status of the certificate using the certificate's serial number or thumbprint. Check the certificate authority's Certificate Revocation List (CRL) or Online Certificate Status Protocol (OCSP) to ensure that the certificate is valid and has not been revoked.Step 5: Validate the Digital Signature AlgorithmSometimes, the error can be caused by an incompatibility between the signing algorithm used to sign the artifact and the verification mechanism being used to validate it. Ensure that the signature algorithm used is supported by the verification process. Check if the verification mechanism requires specific algorithms or cryptographic standards, and verify that the signature algorithm used is compliant.Step 6: Confirm the Trustworthiness of the CertificateThe error could also occur if the certificate used to sign the artifact is not trusted by the verification mechanism. Check the trust anchors, root certificates, or certificate trust lists (CTLs) used by the verification component. Ensure that the certificate used to sign the artifact is present and trusted.Step 7: Verify Time and Date SettingsIncorrect time and date settings on the machine performing the verification can also cause errors during the verification process. Ensure that the system clock is correctly set and synchronized with a reliable time source. An incorrect time or date can cause the verification mechanism to deem the certificate invalid.Step 8: Update Software and Security ComponentsOutdated or incompatible software or security components can introduce compatibility issues that lead to verification errors. Ensure that all relevant software, including certificate authorities, verification libraries, and operating systems, are up to date. Check with the software vendors for any known issues or updates specific to the verification process.Step 9: Seek Assistance from Trusted SourcesIf the above steps do not resolve the issue, it might be beneficial to seek assistance from trusted sources. Reach out to software vendors, certificate authorities, or online forums dedicated to software security and digital signatures. These sources may provide specific guidance or solutions tailored to your particular situation.Conclusion:Verifying signed artifacts is a critical step in ensuring the integrity and authenticity of software. This troubleshooting guide has provided a step-by-step approach to identify and resolve the "verifying signed artifacts" error. By understanding the basics, checking the certificate chain, validating the signing algorithm, and confirming trustworthiness, you can diagnose and rectify common issues that may arise during the verification process. Remember to keep all software up to date and seek assistance when needed. With these steps, you can ensure the successful verification of signed artifacts and maintain the security and trustworthiness of your software.。
