Detected by Coverity. cpumap was allocated with a value of (unsigned short)*(int), which is an int computation, and then promotes to size_t. On a 64-bit platform, this fails if bit 32 of the product is set (because of sign extension giving a HUGE value to malloc), even though a naive programmer would assume that since the first value is unsigned, the product is also unsigned and at most 4GB would be allocated. Won't bite in practice (the product should never be that large), but worth using the right types to begin with, so that we are now computing (unsigned short)*(size_t). * python/libvirt-override.c (libvirt_virDomainGetVcpus): Use correct type.
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.
