void test_access_kernel_obj_with_priv_data

(

void

)

Test access kernel object with private data using system call.

• When defining system calls, it is very important to ensure that access to the API’s private data is done exclusively through system call interfaces. Private kernel data should never be made available to user mode threads directly. For example, the k_queue APIs were intentionally not made available as they store bookkeeping information about the queue directly in the queue buffers which are visible from user mode.
• Current test makes user thread try to access private kernel data within their associated data structures. Kernel will track that system call access to these object with the kernel object permission system. Current user thread doesn't have permission on it, trying to access &pqueue kernel object will happen kernel oops, because current user thread doesn't have permission on k_queue object with private kernel data.
