When Curl_timeleft() < 0 we used to return 0, masking the expiry and skipping the caller’s (timeout_ms < 0) path. Now we set FIN and return the negative value so tftp_multi_statemach() aborts with CURLE_OPERATION_TIMEDOUT as intended.

Also related, but I don't want to send a PR for this because I'm uncertain, it looks like there's a missing check of the return value here (e.g. what happens if the timeout is 0?) |
