The current code pattern requires that callers of qemuMonitorClose check for the return value == 0, and if so, set priv->mon = NULL and release the reference held on the associated virDomainObjPtr The change d84bb6d6a3bd2fdd530184cc9743249ebddbee71 violated that requirement, meaning that priv->mon never gets set to NULL, and a reference count is leaked on virDomainObjPtr. This design was a bad one, so remove the need to check the return valueof qemuMonitorClose(). Instead allow registration of a callback that's invoked just when the last reference on qemuMonitorPtr is released. Finally there was a potential reference leak in qemuConnectMonitor in the failure path. * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add a destroy callback invoked from qemuMonitorFree * src/qemu/qemu_driver.c: Use the destroy callback to release the reference on virDomainObjPtr when the monitor is freed. Fix other potential reference count leak in connecting to monitor
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
