From 2ea7dfcd05bad3b81d63eaac50bf1fc78636de5b Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 22 Feb 2022 15:23:40 +0000 Subject: block/curl.c: Set error message string if curl_init_state() fails MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In curl_open(), the 'out' label assumes that the state->errmsg string has been set (either by curl_easy_perform() or by manually copying a string into it); however if curl_init_state() fails we will jump to that label without setting the string. Add the missing error string setup. (We can't be specific about the cause of failure: the documentation of curl_easy_init() just says "If this function returns NULL, something went wrong".)
