       int prctl(PR_GET_NO_NEW_PRIVS, 0L, 0L, 0L, 0L);

DESCRIPTION         top

       Return the value of the no_new_privs attribute for the calling
       thread.  A value of 0 indicates the regular execve(2) behavior.
       A value of 1 indicates execve(2) will operate in the privilege-
       restricting mode described in PR_SET_NO_NEW_PRIVS(2const).

RETURN VALUE         top

       On success, PR_GET_NO_NEW_PRIVS returns the boolean value
       described above.  On error, -1 is returned, and errno is set to
       indicate the error.

              Since Linux 4.10, the value of a thread's no_new_privs

              file.
