We introduce a novel approach called kCOMALIVE to enhance kernel resilience. kCOMALIVE builds on the state-of-the-art kernel compartments to contain faults and extend them with crash recovery capabilities. kCOMALIVE employs a checkpoint and restore mechanism to enable fine-grained recovery of failed kernel compartments. kCOMALIVE incorporates compile-time instrumentation to simplify compartment constructions and facilitate deployments. We prototyped kCOMALIVE by extending the HAKC framework and showed its effectiveness at recovering a failed Linux driver.trueAvailabilityCompartmentalizationKernel SafetyOperating SystemsReliabilityconference paper10.1145/3765889.37670442-s2.0-105020382490
