lxc: Avoid segfault of libvirt_lxc helper on early cleanup paths
Early jumps to the cleanup label caused a crash of the libvirt_lxc container helper as the cleanup section called virLXCControllerDeleteInterfaces(ctrl) without checking the ctrl argument for NULL. The argument was de-referenced soon after. $ /usr/libexec/libvirt_lxc /usr/libexec/libvirt_lxc: missing --name argument for configuration Segmentation fault (cherry picked from commit 81efb13b4a33f58c28e0e65dcc9521b983592683)
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.
