Detected by Coverity. Commit a98d8f0d tried to make uuid debugging more robust, but missed some APIs. And on the APIs that it visited, the mere act of preparing the debug message ends up dereferencing uuid prior to the null check. Which means the APIs which are supposed to gracefully reject NULL arguments now end up with SIGSEGV. * src/libvirt.c (VIR_UUID_DEBUG): New macro. (virDomainLookupByUUID, virDomainLookupByUUIDString) (virNetworkLookupByUUID, virNetworkLookupByUUIDString) (virStoragePoolLookupByUUID, virStoragePoolLookupByUUIDString) (virSecretLookupByUUID, virSecretLookupByUUIDString) (virNWFilterLookupByUUID, virNWFilterLookupByUUIDString): Avoid null dereference.
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.
