It is not necessary to close stdin, stdout and stderr file descriptors here, if they are open dup2() will close them before copy the new file descriptor.

Do not close the original file descriptor if it is in the 0~MAX_PASS_FD range as in this case it will also close the copied file descriptor (dup2() does nothing when src == dst).
