Hi, My GSoC project proposal <https://docs.google.com/document/d/1AawmqbfCpRDHZ4cO5-UE1J7VacubNWmn3kae4rlPrZA/edit?usp=sharing> intended for providing thread-stack protection involves implementation on two levels, providing low-level hardware support for the target architecture and high-level architecture-independent APIs. As @Peter Dufault <dufa...@hda.com> pointed to me in my draft the POSIX compliant way of doing it would be through mmap, I would request your feedback on the details of the high-level implementation of thread-stack protection. My idea is to obtain the stack attributes of the thread that is to be mapped by pthread_attr_getstack() and then get a file descriptor of the memory using posix_typed_mem_open() and finally mmap that to the stack of the required thread(With the specified permissions). Is this is a valid approach? If yes, I believe I would have to add the implementation of posix_typed_mem_open() to my work plan as RTEMS does not support it as of now.
Regards, Utkarsh Rai.
