which frees all allocated memory but doesn't set the passed pointer to NULL. Therefore, we must do it ourselves. This is causing actual libvirtd crash: Basically, when doing 'virsh net-edit' the newDef should be dropped. And the memory is freed, indeed. However, the pointer is not set to NULL but kept instead. And the next duo of calls 'virsh net-start' and 'virsh net-destroy' starts the disaster. The latter one does the same as 'virsh destroy'; it sees that newDef is nonNULL so it replaces def with newDef (which has been freed already as said a few lines above). Therefore any subsequent call accessing def will hit the ground. (cherry picked from commit b7e9202401ebaa039b8f05acdefda8c24081537a)
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.
