Problem Details: When clone fails after the shadow stack is allocated, any allocated shadow stack is cleaned up in exit_thread() in copy_process(). So the logic in copy_thread() is unneeded, and also will not handle failures that happen outside of copy_thread(). In addition, since there is a second attempt to unmap th...
