| 摘要: |
| 并发错误是程序设计语言和软件工程领域的研究热点之一.近年来，针对应用程序并发错误检测的研究已取得了很大进展.但是由于操作系统内核的并发和同步机制复杂、代码规模庞大，与应用程序级并发错误检测相比，操作系统内核的并发错误检测研究仍面临巨大的挑战.对此，国内外学者提出了各种用于操作系统内核并发错误检测的方法.首先介绍了并发错误的基本类型、检测方法和评价指标，讨论了现有的并发错误检测方法和工具的局限性；然后，从形式化验证、静态分析、动态分析和静态动态相结合4个方面，对现有的操作系统内核并发错误检测的研究工作进行了分类阐述，并作了系统总结和对比分析；最后，探讨了操作系统内核并发错误检测研究面临的挑战，并对该领域未来的研究趋势进行了展望. |

| Abstract: |
| Concurrency bug detection is a hot research topic in the area of programming language and software engineering. In recent years, researchers have made great progress in concurrency bug detection of applications. However, as operating system (OS) kernels always have high concurrency, complex synchronization mechanisms, and large scale of source codes, researches on concurrency bug detection of OS kernels are more challenging than applications. To address this issue, researchers have proposed various approaches to detect concurrency bugs in OS kernels. This study first introduces the basic types, detection techniques, and evaluation indicators of concurrency bug detection, and the limitations of existing concurrency bug detection tools in OS kernels are discussed. Then, researches on concurrency bug detection in OS kernels are described from four aspects:Formal verification, static analysis, dynamic analysis, and combination of both static and dynamic analysis. Some typical approaches are comprehensively compared. Finally, the challenges of concurrency bug detection in OS kernels are discussed, and the future research trends in this field are prospected. |
