ACL2 Seminar, 4/28/2017 Speaker: Mihir Mehta Title: Verifying filesystems in ACL2 Abstract: Modern filesystems are growing more reliable against data loss, data corruption and data races in multiprogramming environments; however, this comes at the cost of increased complexity of implementation and a higher vulnerability to bugs. In this talk, we describe a work in progress to incrementally build a verified model of a filesystem that is binary compatible with the CP/M filesystem, and our future plans to model more complex filesystems including FAT32.
