DeepErr: Automatic Root-Cause Analysis of System Call Failures

System call failures present significant challenges for operating system (OS) users, as the failures are often cryptic and difficult to diagnose due to limited error codes and missing documentation. As a result, software developers struggle to utilize system calls effectively, and power users encounter difficulties configuring the OS and resolving environment problems. Existing automatic root-cause analysis tools are inadequate, primarily due to dependence on comparative analysis, which requires similar successful executions that are often unavailable.
