The VINO Extensible Operating System: Motivation and Performance
Harvard University

A safe extensible operating system allows untrusted users to modify the behavior of the operating system kernel without compromising its safety or security. The VINO project, at Harvard University, has focused on understanding the requirements for safety and security in such an extensible system, and the architectural choices and trade-offs that are made when building such a system.

In my talk I will motivate the development of an extensible system and discuss its safety requirements. I will describe the safety and security technology developed for the VINO project, the MiSFIT software fault isolation tool and the VINO lightweight transaction mechanism. I will also present the result of experiments that measure the end-to-end performance of applications running on VINO, and describe the circumstances under which the costs of extensibility in VINO are made up for by the benefits of giving applications control over kernel policy.
