From 88011ed280c4f946a7b8e7ffcea2335eb075de60 Mon Sep 17 00:00:00 2001 From: Jim Fehlig Date: Fri, 3 Apr 2020 15:51:48 -0600 Subject: [PATCH] libxl: fix crash when initializing driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 54a401af478 split out DriverConfigInit from DriverConfigNew, but then called it a bit late from libxlStateInitialize. The cfg is used in libxlDriverConfigLoadFile and when uninitialized results in a crash. Calling DriverConfigInit immediately after DriverConfigNew fixes the crash.
