WitrynaThen, with these pairs, DCUAF performs a summary-based lockset analysis to detect concurrency use-after-free bugs. We have evaluated DCUAF on the driver code of Linux 4.19, and found 640 real concurrency use-after-free bugs. We have randomly selected 130 of the real bugs and reported them to Linux kernel developers, and 95 have been … Witrynasolution: the program is initially run using lockset analysis to identify problematic fields (“simple mode”) and if any are detected the program is re-run using a combined lockset and happens-before analysis for just those fields (“detailed mode”) [22].

Effective static analysis of concurrency use-after-free bugs in …
WitrynaProbabilistic Lockset Analysis. Based on these observa-tions, we introduce Probabilistic Lockset Analysis (PLA): a new analysis for kernel race prediction that identifies mem-ory accesses in the stable set and performs synchronization aware race prediction on them. PLA works by estimating the probability that two seeds can execute racing … WitrynaAnalysis Accuracy: For observed executions, due to using a sampling strategy, the analysis is unsound (false negatives possible), but aims to be complete (no false … breakdown\\u0027s rn
ACCULOCK: Accurate and Efficient Detection of Data Races
Witryna4 sty 2024 · The static detection method is mainly detected by lockset analysis, which has the problem of more false positives . Dynamic data race detection methods … WitrynaIn this paper, we report on our experiences with a static data race detector. We define a basic analysis based on classical lockset analysis and present three enhancements to that algorithm. We evaluate and compare the effectiveness of the basic and enhanced analysis algorithms empirically for an automotive embedded system. WitrynaLockset Analysis Lockset analysis is a lightweight race detection method proposed in the context of Eraser [23], a dynamic data race detector. The idea is to track the set of … costco chicken tortilla soup ingredients
