It was possible for an unprivileged task to invoke any function with privilege by passing it as a parameter to MPU_xTaskCreate, MPU_xTaskCreateStatic, MPU_xTimerCreate, MPU_xTimerCreateStatic, or MPU_xTimerPendFunctionCall. This commit ensures that MPU_xTaskCreate and MPU_xTaskCreateStatic can only create unprivileged tasks. It also removes the following APIs: 1. MPU_xTimerCreate 2. MPU_xTimerCreateStatic 3. MPU_xTimerPendFunctionCall We thank Huazhong University of Science and Technology for reporting this issue. Signed-off-by: Gaurav Aggarwal <aggarg@amazon.com>
Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the five sample memory allocators as described on the https://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler, where the directory name denotes the compiler specific files the directory contains. For example, if you are interested in the [compiler] port for the [architecture] microcontroller, then the port specific files are contained in FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the only port you are interested in then all the other directories can be ignored.
