For some reason, we allow a bridge name with %d in it, which we replace with an unsigned integer to form a bridge name that does not yet exist on the host. Do not blindly pass it to virAsprintf if it's not the only conversion, to prevent crashing on input like: <network> <name>test</name> <forward mode='none'/> <bridge name='virbr%d%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s'/> </network> Ignore any template strings that do not have exactly one %d conversion, like we do in various drivers before calling virNetDevTapCreateInBridgePort.
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.
