The File System Most file system functions are left to untrusted library file systems libFSes —Will share access to the stable storage disk —Can define new file systdms with arbitrary metadata formats Problem is to give maximum of flexibility to these libFses while protecting files from unauthorized accesses.

Write a constructive review, including one unique discussion question, and submit that review to Piazza by 9pm or so of the day before the class in which we discuss the paper.

XN I Provides access to stable storage at the level of disk blocks Fledibility a buffer cache registry contains only metadata Main problem is to decide when to allow or disallow access to a specific block —Difficult problem because each libFS may use different metadata.

This paper describes an exokernel system that allows specialized applications to achieve high performance without sacrificing the performance of unmodified UNIX programs. Proceedings of OSDI By the time you finish the class, you should have a good understanding of the problems that have faced OS designers over about the past 50 years, how they solve them, and how these systems relate to OS and system design issues today.

The results show that common unmodified UNIX applications can enjoy the benefits of exokernels: This qpplication surveys research literature relating flexibilityy the design and implementation of operating systems. It evaluates the exokernel architecture by measuring end-to-end application performance on Xok, an exokernel for Intel xbased computers, and by comparing Xok’s performance to the performance of two widely-used 4.
