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>
