Auto-port 4.1: Native transports: Fix possible fd leak when fcntl fails.#16446
Merged
Conversation
Motivation: When accept4(...) is not present on the platform we fallback to using normal accept(...) syscall. In this case we also need two extra syscalls (fcntl). If one of the fcntl calls failed we did not close the previous accepted fd and so leaked it. Modifications: Call close(...) before returning early Result: No more fd leak in case of fcntl failure (cherry picked from commit 9f2900f)
