From 7cfa154d15c4a98bea0cfe26b2c78094a094650f Mon Sep 17 00:00:00 2001 From: Daniel Gustafsson Date: Wed, 17 Jan 2024 11:24:11 +0100 Subject: [PATCH] Close socket in case of errors in setting non-blocking If configuring the newly created socket non-blocking fails we error out and return INVALID_SOCKET, but the socket that had been created wasn't closed. Fix by issuing closesocket in the errorpath. Backpatch to all supported branches.
