This is the memory safety proof for FreeRTOS_OutputARPRequest method combined with the BufferAllocation_1.c allocation strategy.

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:

  • vPortEnterCritical
  • vPortExitCritical
  • vPortGenerateSimulatedInterrupt
  • vAssertCalled
  • xTaskGetSchedulerState
  • pvTaskIncrementMutexHeldCount
  • xTaskRemoveFromEventList
  • xTaskPriorityDisinherit

This proof checks FreeRTOS_OutputARPRequest in multiple configurations. All assume the memory safety of vNetworkInterfaceAllocateRAMToBuffers.

  • The config_minimal_configuration proof sets ipconfigUSE_LINKED_RX_MESSAGES=0.
  • The config_minimal_configuration_linked_rx_messages proof sets ipconfigUSE_LINKED_RX_MESSAGES=1.
  • The minimal_configuration_minimal_packet_size proof sets ipconfigETHERNET_MINIMUM_PACKET_BYTES to 50.

All harnesses include the queue.c file, but test only for the happy path.
