摘要

提出了一种新的安全内核扩展编程接口层P-Bus。P-Bus在Linux内核之上引入了一个新的编程接口，以便为接口提供正式的规范，并提高扩展的可移植性。新的扩展(称为P-Components)使用模型检查器MKencha进行验证，以查看组件是否符合正确实现扩展应遵守的规则。网络驱动程序已经作为P-Component实现，并通过MKencha进行了验证。MKencha在该组件中发现了两个bug。

P-Bus: Programming Interface Layer for Safe OS Kernel Extensions

P-Bus, a new programming interface layer for safe kernel extensions is proposed. P-Bus introduces a new programming interface on top of the Linux kernel in order to give formal specifications to the interface, and to improve portability of extensions. New extensions, called P-Components, are verified with a model checker MKencha to see whether a component is compliant with rules which should be obeyed to implement extensions properly. A network driver has been implemented as a P-Component and verified with MKencha. MKencha has found two bugs in the component.
