Basically dnsmasq limits itself by default to 150 leases maximum. Which means we may inflict an arbitrary limit in the number of domains running on a given host https://bugzilla.redhat.com/show_bug.cgi?id=524280 The patches do 3 things: - first introduce IPv4 and IPv6 parsing routines, generally useful this could be used to double check input in other places too - then when a DHCP range is defined use those routines to parse the start and end, do some cheking and keep the range size in the structure - last when exec'ing dnsmasq compute the sum of all dhcp ranges and pass the max lease option Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@xxxxxxxxxxxx | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/ -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
