驱动程序正在成为操作系统内核的大部分。以前的研究表明，设备驱动程序似乎是操作系统错误行为的最重要来源之一。它们的故障可能会对内核产生重大影响，并对整个系统造成重大损害。为了客观地描述故障驱动程序的影响，我们进行了一系列的故障注入实验。为了进行这些实验，我们针对的是DPI（驱动程序编程接口），它实现了设备驱动程序与内核交互的方式。错误被注入到这些内核核心连接的参数上。这允许导出有关引起的故障模式的有用结果，从而表征目标内核相对于故障驱动程序的鲁棒性。所收集的信息还有助于改进这些互动设施。
Drivers are becoming the larger part of operating systems kernels. Previous studies have shown that device drivers seem to be one of the most important sources of operating systems misbehavior. Their failure can have significant impact on the kernel and cause significant damages to the system as a whole. To objectively characterize the impact of faulty drivers, we have carried out a series of fault injection experiments. To conduct these experiments we have targeted the DPI (Driver Programming Interface) that implements the way device drivers interact with the kernel. Faults are injected on the parameters of these kernel core Junctions. This allows for the derivation of useful results about the failure modes induced and thus characterization of the robustness of a target kernel with respect to faulty drivers. The information gathered also enables to improve these interaction facilities.
