Laine Stump 1cb1f9dabf network: always create dnsmasq hosts and addnhosts files, even if empty ... This fixes the problem reported in: https://bugzilla.redhat.com/show_bug.cgi?id=868389 Previously, the dnsmasq hosts file (used for static dhcp entries, and addnhosts file (used for additional dns host entries) were only created/referenced on the dnsmasq commandline if there was something to put in them at the time the network was started. Once we can update a network definition while it's active (which is now possible with virNetworkUpdate), this is no longer a valid strategy - if there were 0 dhcp static hosts (resulting in no reference to the hosts file on the commandline), then one was later added, the commandline wouldn't have linked dnsmasq up to the file, so even though we create it, dnsmasq doesn't pay any attention. The solution is to just always create these files and reference them on the dnsmasq commandline (almost always, anyway). That way dnsmasq can notice when a new entry is added at runtime (a SIGHUP is sent to dnsmasq by virNetworkUdpate whenever a host entry is added or removed) The exception to this is that the dhcp static hosts file isn't created if there are no lease ranges *and* no static hosts. This is because in this case dnsmasq won't be setup to listen for dhcp requests anyway - in that case, if the count of dhcp hosts goes from 0 to 1, dnsmasq will need to be restarted anyway (to get it listening on the dhcp port). Likewise, if the dhcp hosts count goes from 1 to 0 (and there are no dhcp ranges) we need to restart dnsmasq so that it will stop listening on port 67. These special situations are handled in the bridge driver's networkUpdate() by checking for ((bool) nranges||nhosts) both before and after the update, and triggering a dnsmasq restart if the before and after don't match.		2012-10-20 21:29:19 -04:00
