Please add some commit message. I don't understand what this patch
does. How is it broken, and how does it fix it?

DOWN is used to stop the server. How would 'continue' help?
$ MANWIDTH=66 man unix | grep -C2 DOWN
tegers. The client prints the sum and exits. The server
waits for the next client to connect. To stop the server,
the client is called with the command‐line argument "DOWN".
The following output was recorded while running the server
in the background and repeatedly executing the client. Ex‐
ecution of the server program ends when it receives the
"DOWN" command.
Example output
--
$ ./client 11 -5
Result = 6
$ ./client DOWN
Result = 0
[1]+ Done ./server
--
/* Handle commands. */
if (!strncmp(buffer, "DOWN", sizeof(buffer))) {
down_flag = 1;
break;
--
close(data_socket);
/* Quit on DOWN command. */
if (down_flag) {
Have a lovely day,
