Previously this function relied on having ATTRIBUTE_NONNULL(1) in its prototype rather than explicitly checking for a null ifname. Unfortunately, ATTRIBUTE_NONNULL is just a hint to the optimizer and code analyzers like Coverity, it doesn't actually check anything at execution time, so the result was possible warnings from Coverity, along with the possibility of null dereferences when ifname wasn't available. This patch removes the ATTRIBUTE_NONNULL from the prototype, and checks ifname inside the function, logging an error if it's NULL (once we've determined that the user really is trying to set a bandwidth).
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.
