conf: Don't crash on invalid chardev source definition of RNGs and other Since commit 297c99a5 an invalid source definition XML of a character device that is used as backend for RNG devices, smartcards and redirdevs causes crash of the daemon when parsing such a definition. The device types mentioned above are not a part of a regular character device but are backends for other types. Thus when parsing such device NULL is passed as the argument @chr_def. Later when checking the validity of the definition @chr_def was dereferenced when parsing a UNIX socket backend with missing path of the socket and crashed the daemon. Sample offending configuration: <devices> ... <rng model='virtio'> <backend model='egd' type='unix'> <source mode='bind' service='1024'/> </backend> </rng> </devices> Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1012196 2013-09-26 06:12:39 +00:00			`<domain type='qemu'>`
