Several APIs clear out a user input buffer before attempting to populate it; but in a few cases we missed this memset if we detect a reason for an early exit. Note that these APIs check for non-NULL arguments, and exit early with an error message when NULL is passed in; which means that we must be careful to avoid a NULL deref in order to get to that error message. Also, we were inconsistent on the use of sizeof(virType) vs. sizeof(expression); the latter is more robust if we ever change the type of the expression (although such action is unlikely since these types are part of our public API). * src/libvirt.c (virDomainGetInfo, virDomainGetBlockInfo) (virStoragePoolGetInfo, virStorageVolGetInfo) (virDomainGetJobInfo, virDomainGetBlockJobInfo): Move memset before any returns.

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.
