From 86dec715a7339fc61c3bdb9715993b277b2089db Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Tue, 5 Sep 2023 12:23:32 -0400 Subject: [PATCH] migration/qmp: Fix crash on setting tls-authz with null MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit QEMU will crash if anyone tries to set tls-authz (which is a type StrOrNull) with 'null' value. Fix it in the easy way by converting it to qstring just like the other two tls parameters.
