Assuming that the parameter is valid mutex data structure and reasonable bounded, this harness proves the memory safety of QueueTakeMutexRecursive. Task pool and concurrency functions are abstracted away and replaced with required stubs to drive coverage.

This proof is a work-in-progress. Proof assumptions are described in the harness. The proof also assumes the following functions are memory safe and have no side effects relevant to the memory safety of this function:

  • pvTaskIncrementMutexHeldCount
  • vPortEnterCritical
  • vPortExitCritical
  • vPortGenerateSimulatedInterrupt
  • vTaskMissedYield
  • vTaskPlaceOnEventList
  • vTaskPriorityDisinheritAfterTimeout
  • vTaskSuspendAll
  • xTaskGetCurrentTaskHandle
  • xTaskPriorityDisinherit
  • xTaskPriorityInherit
  • xTaskRemoveFromEventList
  • xTaskResumeAll
