Re: [libvirt] [PATCH 05/12] debug: avoid null dereference on uuid lookup api

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. ---  src/libvirt.c |   42 ++++++++++++++++++++++++++----------------  1 files changed, 26 insertions(+), 16 deletions(-)
