With support for multiple IP addresses per interface in place, this patch now adds support for multiple IP addresses per interface for the DHCP snooping code. Testing: Since the infrastructure I tested this with does not provide multiple IP addresses per MAC address (anymore), I either had to plug the VM's interface from the virtual bride connected directly to the infrastructure to virbr0 to get a 2nd IP address from dnsmasq (kill and run dhclient inside the VM) or changed the lease file (/var/run/libvirt/network/nwfilter.leases) and restart libvirtd to have a 2nd IP address on an existing interface. Note that dnsmasq can take a lease timeout parameter as part of the --dhcp-range command line parameter, so that timeouts can be tested that way (--dhcp-range 192.168.122.2,192.168.122.254,120). So, terminating and restarting dnsmasq with that parameter is another choice to watch an IP address disappear after 120 seconds. Regards, Stefan
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.
