2016-03-01udhcpd: keep expired leases at startupChristian Lindeberg
Let udhcpd retain the information about expired leases when restarting so that the leases are reserved until they possibly become the oldest expired lease. This reduces the frequency of IP address changes for example when the DHCP server and a group of clients, who do not store and request their previously offered IP address across restarts, are collectively restarted and the startup order of the clients are not guaranteed.

2016-03-01ifupdown: allow duplicate interface definitionsNicolas Cavallari
This patch allow to have multiple interface definitions, much like Debian's ifupdown. More specifically, it removes the check for a duplicate definition, so the impact on binary size should be fairly minimal. This configuration: iface eth0 inet static address 192.168.0.15 netmask 255.255.0.0 gateway 192.168.0.1 iface eth0 inet static address 10.0.0.1 netmask 255.255.255.0 Will add two addresses to eth0 if ip is used. If ifconfig is used, the standards methods will likely not stack, but the administrator may still use the manual method. The DHCP method may work depending on the DHCP client in use. This is a fairly advanced feature for power users who knows what they are doing. There are not many other network configuration systems that allows multiple addresses on an interface.
