Memory Protection Unit (MPU) Enhancements (#705) Memory Protection Unit (MPU) Enhancements This commit introduces a new MPU wrapper that places additional restrictions on unprivileged tasks. The following is the list of changes introduced with the new MPU wrapper: 1. Opaque and indirectly verifiable integers for kernel object handles: All the kernel object handles (for example, queue handles) are now opaque integers. Previously object handles were raw pointers. 2. Saving the task context in Task Control Block (TCB): When a task is swapped out by the scheduler, the task's context is now saved in its TCB. Previously the task's context was saved on its stack. 3. Execute system calls on a separate privileged only stack: FreeRTOS system calls, which execute with elevated privilege, now use a separate privileged only stack. Previously system calls used the calling task's stack. The application writer can control the size of the system call stack using new configSYSTEM_CALL_STACK_SIZE config macro. 4. Memory bounds checks: FreeRTOS system calls which accept a pointer and de-reference it, now verify that the calling task has required permissions to access the memory location referenced by the pointer. 5. System call restrictions: The following system calls are no longer available to unprivileged tasks: - vQueueDelete - xQueueCreateMutex - xQueueCreateMutexStatic - xQueueCreateCountingSemaphore - xQueueCreateCountingSemaphoreStatic - xQueueGenericCreate - xQueueGenericCreateStatic - xQueueCreateSet - xQueueRemoveFromSet - xQueueGenericReset - xTaskCreate - xTaskCreateStatic - vTaskDelete - vTaskPrioritySet - vTaskSuspendAll - xTaskResumeAll - xTaskGetHandle - xTaskCallApplicationTaskHook - vTaskList - vTaskGetRunTimeStats - xTaskCatchUpTicks - xEventGroupCreate - xEventGroupCreateStatic - vEventGroupDelete - xStreamBufferGenericCreate - xStreamBufferGenericCreateStatic - vStreamBufferDelete - xStreamBufferReset Also, an unprivileged task can no longer use vTaskSuspend to suspend any task other than itself. We thank the following people for their inputs in these enhancements: - David Reiss of Meta Platforms, Inc. - Lan Luo, Xinhui Shao, Yumeng Wei, Zixia Liu, Huaiyu Yan and Zhen Ling of School of Computer Science and Engineering, Southeast University, China. - Xinwen Fu of Department of Computer Science, University of Massachusetts Lowell, USA. - Yuequi Chen, Zicheng Wang, Minghao Lin of University of Colorado Boulder, USA.

Add Access Control List to MPU ports (#765) This PR adds Access Control to kernel objects on a per task basis to MPU ports. The following needs to be defined in the `FreeRTOSConfig.h` to enable this feature: ```c #define configUSE_MPU_WRAPPERS_V1 0 #define configENABLE_ACCESS_CONTROL_LIST 1 ``` This PR adds the following new APIs: ```c void vGrantAccessToTask( TaskHandle_t xTask, TaskHandle_t xTaskToGrantAccess ); void vRevokeAccessToTask( TaskHandle_t xTask, TaskHandle_t xTaskToRevokeAccess ); void vGrantAccessToSemaphore( TaskHandle_t xTask, SemaphoreHandle_t xSemaphoreToGrantAccess ); void vRevokeAccessToSemaphore( TaskHandle_t xTask, SemaphoreHandle_t xSemaphoreToRevokeAccess ); void vGrantAccessToQueue( TaskHandle_t xTask, QueueHandle_t xQueueToGrantAccess ); void vRevokeAccessToQueue( TaskHandle_t xTask, QueueHandle_t xQueueToRevokeAccess ); void vGrantAccessToQueueSet( TaskHandle_t xTask, QueueSetHandle_t xQueueSetToGrantAccess ); void vRevokeAccessToQueueSet( TaskHandle_t xTask, QueueSetHandle_t xQueueSetToRevokeAccess ); void vGrantAccessToEventGroup( TaskHandle_t xTask, EventGroupHandle_t xEventGroupToGrantAccess ); void vRevokeAccessToEventGroup( TaskHandle_t xTask, EventGroupHandle_t xEventGroupToRevokeAccess ); void vGrantAccessToStreamBuffer( TaskHandle_t xTask, StreamBufferHandle_t xStreamBufferToGrantAccess ); void vRevokeAccessToStreamBuffer( TaskHandle_t xTask, StreamBufferHandle_t xStreamBufferToRevokeAccess ); void vGrantAccessToMessageBuffer( TaskHandle_t xTask, MessageBufferHandle_t xMessageBufferToGrantAccess ); void vRevokeAccessToMessageBuffer( TaskHandle_t xTask, MessageBufferHandle_t xMessageBufferToRevokeAccess ); void vGrantAccessToTimer( TaskHandle_t xTask, TimerHandle_t xTimerToGrantAccess ); void vRevokeAccessToTimer( TaskHandle_t xTask, TimerHandle_t xTimerToRevokeAccess ); ``` An unprivileged task by default has access to itself only and no other kernel object. The application writer needs to explicitly grant an unprivileged task access to all the kernel objects it needs. The best place to do that is before starting the scheduler when all the kernel objects are created. For example, let's say an unprivileged tasks needs access to a queue and an event group, the application writer needs to do the following: ```c vGrantAccessToQueue( xUnprivilegedTaskHandle, xQueue ); vGrantAccessToEventGroup( xUnprivilegedTaskHandle, xEventGroup ); ``` The application writer MUST revoke all the accesses before deleting a task. Failing to do so will result in undefined behavior. In the above example, the application writer needs to make the following 2 calls before deleting the task: ```c vRevokeAccessToQueue( xUnprivilegedTaskHandle, xQueue ); vRevokeAccessToEventGroup( xUnprivilegedTaskHandle, xEventGroup ); ```

Memory Protection Unit (MPU) Enhancements (#705) Memory Protection Unit (MPU) Enhancements This commit introduces a new MPU wrapper that places additional restrictions on unprivileged tasks. The following is the list of changes introduced with the new MPU wrapper: 1. Opaque and indirectly verifiable integers for kernel object handles: All the kernel object handles (for example, queue handles) are now opaque integers. Previously object handles were raw pointers. 2. Saving the task context in Task Control Block (TCB): When a task is swapped out by the scheduler, the task's context is now saved in its TCB. Previously the task's context was saved on its stack. 3. Execute system calls on a separate privileged only stack: FreeRTOS system calls, which execute with elevated privilege, now use a separate privileged only stack. Previously system calls used the calling task's stack. The application writer can control the size of the system call stack using new configSYSTEM_CALL_STACK_SIZE config macro. 4. Memory bounds checks: FreeRTOS system calls which accept a pointer and de-reference it, now verify that the calling task has required permissions to access the memory location referenced by the pointer. 5. System call restrictions: The following system calls are no longer available to unprivileged tasks: - vQueueDelete - xQueueCreateMutex - xQueueCreateMutexStatic - xQueueCreateCountingSemaphore - xQueueCreateCountingSemaphoreStatic - xQueueGenericCreate - xQueueGenericCreateStatic - xQueueCreateSet - xQueueRemoveFromSet - xQueueGenericReset - xTaskCreate - xTaskCreateStatic - vTaskDelete - vTaskPrioritySet - vTaskSuspendAll - xTaskResumeAll - xTaskGetHandle - xTaskCallApplicationTaskHook - vTaskList - vTaskGetRunTimeStats - xTaskCatchUpTicks - xEventGroupCreate - xEventGroupCreateStatic - vEventGroupDelete - xStreamBufferGenericCreate - xStreamBufferGenericCreateStatic - vStreamBufferDelete - xStreamBufferReset Also, an unprivileged task can no longer use vTaskSuspend to suspend any task other than itself. We thank the following people for their inputs in these enhancements: - David Reiss of Meta Platforms, Inc. - Lan Luo, Xinhui Shao, Yumeng Wei, Zixia Liu, Huaiyu Yan and Zhen Ling of School of Computer Science and Engineering, Southeast University, China. - Xinwen Fu of Department of Computer Science, University of Massachusetts Lowell, USA. - Yuequi Chen, Zicheng Wang, Minghao Lin of University of Colorado Boulder, USA.
