Most callers of qemuParseKeywords were assigning its return value to a 'size_t' variable. Then then also checked '< 0' for error condition, but this will never be true with the unsigned size_t variable. Rather than using 'ssize_t', change qemuParseKeywords so that the element count is returned via an output parameter, leaving the return value solely as an error indicator. This avoids a crash accessing beyond the end of an error upon OOM. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
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.
