Modern operating systems are large and complex code bases in whichhundreds of programmer-years have been invested. As a result,modifying an operating system is a difficult, costly, and oftenimpractical endeavor. However, viewing the OS as an immutable objectis at odds with most OS research.This research proposes techniques that enable the deployment of OSideas without changing OS source code. The thesis is that an OS-likeservice can acquire information about the internal state of the OS andcontrol its behavior, even when no explicit interfaces to do so areprovided. With this approach, the OS is treated as a gray box, inwhich the general characteristics of its algorithms are known; thisknowledge is then combined with run-time observations of how the OS reactsto probes in order to infer its state and exert control.Initial experience with gray-box systems points to additional areas ofresearch: automated discovery of algorithms, on-line benchmarking toconfigure parameters, dynamic insertion of probes, and aggressiveinference of OS internal state. Thus, the goal of this proposal istwo-fold: to understand the theoretical foundations of gray-boxsystems and to implement a toolbox of software for the rapiddevelopment of gray-box systems.

现代操作系统是大型且复杂的代码库，其中已投资了数百个程序员年。结果，修改操作系统是一项困难，昂贵且常常不错的工作。但是，将操作系统视为与大多数OS研究不一致的不变对象。这项研究提出的技术可以在不更改OS源代码的情况下部署osideas。论点是，即使没有明确的接口可以进行此操作，OS-Likeservice也可以获取有关OS内部状态和控制其行为的内部状态的信息。通过这种方法，OS被视为灰色盒子，这是其算法的一般特征。然后将此知识与OS ReactSto探针如何推断其状态并发挥控制的运行时观察结合。具有灰色框系统的原始体验指向研究的其他领域：算法的自动发现，在线基准标准，将概述参数，探针插入，动态插入，以及攻击性的Internalsentenfere Internalference。 因此，该提案的目标是：了解灰色盒系统的理论基础，并实施用于快速开发灰色系统系统的软件工具箱。
