Coverity complained about the usage of the uninitialized cacerts in the event(s) that "access(certFile, R_OK)" and/or "access(cacertFile, R_OK)" fail the for loop used to fill in the certs will have indeterminate data as well as the possibility that both failures would result in the gnutls_x509_crt_deinit() call having a similar fate. Initializing cacerts only would resolve the issue; however, it still would leave the indeterminate action, so rather add a parameter to the virNetTLSContextLoadCACertListFromFile() to pass the max size rather then overloading the returned count parameter. If the the call is never made, then we won't go through the for loops referencing the empty cacerts
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.
