Dennis and Earl C. Laboratory for Computer Science. Published by Tobias Conley Modified over 3 years ago. Auth with social network: The File System Most file system functions are exokegnel to untrusted library file systems libFSes —Will share access to the stable storage disk —Can define new file types with arbitrary metadata formats Problem is to give maximum of flexibility to these libFses while protecting files from unauthorized accesses.

To make this website work, we log user data and share it with processors. Applications that do not want this responsibility communicate with the exokernel through libOSes. On the Duality of Operating System Structures.

A Modern Perspective, Chapter The results show that common unmodified UNIX applications can enjoy the benefits of exokernels: A new OS architecture for scalable multicore systems. XN I Provides access to stable storage at the level of disk blocks Exports 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.
