Fix the null pointer access when UUID is not specified.
Introduce a bool 'uuidUsable' to virStoragePoolAuthCephx that indicates
if uuid was specified or not and use it instead of the pointless
comparison of the static UUID array to NULL.
Add an error message if both uuid and usage are specified.
Fixes:
Error: FORWARD_NULL (CWE-476):
libvirt-0.10.2/src/conf/storage_conf.c:461: var_deref_model: Passing
null pointer "uuid" to function "virUUIDParse(char const *, unsigned
char *)", which dereferences it. (The dereference is assumed on the
basis of the 'nonnull' parameter attribute.)
Error: NO_EFFECT (CWE-398):
libvirt-0.10.2/src/conf/storage_conf.c:979: array_null: Comparing an
array to null is not useful: "src->auth.cephx.secret.uuid != NULL".
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.
