- Abstract
- The past decade has seen a rapid acceleration in the development of new and transformative applications in many areas including transportation, medicine, finance, and communication. Most of these applications are made possible by the increasing diversity and scale of hardware and software systems. While this brings unprecedented opportunity, it also increases the probability of failures and the difficulty of diagnosing them. Increased scale and transience has also made management increasingly challenging. Devices can come and go for a variety of reasons including mobility, failure and recovery, and scaling capacity to meet demand. This thesis presents several systems that I built to address the resulting challenges to reliability, management, and security. Ori is a reliable distributed file system for devices at the network edge. Ori automates many of the tasks of storage reliability and recovery through replication, taking advantage of fast LANs and low cost local storage in edge networks. Castor is a record/replay system for multi-core applications with predictable and consistently low overheads. This makes it practical to leave record/replay on in production systems, to reproduce difficult bugs when they occur, and to support recovering from hardware failures through fault tolerance. Cryptographic CFI (CCFI) is a dynamic approach to control flow integrity. Unlike previous CFI systems that rely purely on static analysis, CCFI can classify pointers based on dynamic and runtime characteristics. This limits the attacks to only actively used code paths, resulting in a substantially smaller attack surface.
