From dbb74759fae6f521709e16e19cbb7d6fb2307700 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Tue, 28 Feb 2017 12:08:15 +0000 Subject: [PATCH] hw/arm/virt: fix cpu object reference leak object_new(FOO) returns an object with ref_cnt == 1 and following object_property_set_bool(cpuobj, true, "realized", NULL) set parent of cpuobj to '/machine/unattached' which makes ref_cnt == 2. Since machvirt_init() doesn't take ownership of cpuobj returned by object_new() it should explicitly drop reference to cpuobj when dangling pointer is about to go out of scope like it's done pc_new_cpu() to avoid object leak.
