Subject: [Qemu-devel] [PATCH] pci: fix double free of romfile property
Date: Thu, 15 Mar 2012 11:29:56 -0500 [thread overview]
Message-ID: <1331828996-17164-1-git-send-email-aliguori@us.ibm.com> (raw)
The qdev property release function frees any string properties. This was
resulting in a double free during hot unplug.
It manifests in network devices because block devices have a NULL romfile
property by default.
