dhcpv4: offer a valid configuration with DHCP NAK
2014-08-12dhcpv4: offer a valid configuration with DHCP NAKChristian Mehlis
On network change the client requests a non valid configuration. In this case we have to reply with a DHCP NAK. But this NAK can include a valid configuration like an ACK does. With this change iDevices and Androids can finish DHCP even with wrong configuration in first REQUEST with two packets and without any additional timeouts and round trips.
2014-08-12dhcpv4: implement router configuration optionChristian Mehlis
RFC 2132 defines: 3.5. Router Option The router option specifies a list of IP addresses for routers on the client's subnet. Routers SHOULD be listed in order of preference. The code for the router option is 3. The minimum length for the router option is 4 octets, and the length MUST always be a multiple of 4. Code Len Address 1 Address 2 +-----+-----+-----+-----+-----+-----+-----+-----+-- | 3 | n | a1 | a2 | a3 | a4 | a1 | a2 | ... +-----+-----+-----+-----+-----+-----+-----+-----+--

2014-07-01DHCPv6 destination address checkHans Dedecker

2014-07-01DHCPv4: send DHCPNAK if requested addr != leased addrSteven Barth
2014-06-30leasefile: do not output expired dhcpv6 leasesNikolay Martynov
Sometimes ip that is assigned to a host changes, old ip is still kept aroung as 'expired'. This expired ip gets dumped into leasefile and is read by dnsmasq. The result is that hotsname is resolved into expired ip and that confuses clients. This patch prevents expired leases from being written into leasefile.

2014-04-23Add status code ok option in reply to a decline messageHans Dedecker
RFC3315 Section 18.2.7 states a status code OK needs to be returned by the server : After all the addresses have been processed, the server generates a Reply message and includes a Status Code option with the value Success, a Server Identifier option with the server's DUID, and a Client Identifier option with the client's DUID.
2014-04-23Don't return a DHCPv6 reply in response to a confirm without address(es)Hans Dedecker
RFC3315 Section 18.2.2 states no reply must returned by the server in case no address(es) are present : If the server is unable to perform this test (for example, the server does not have information about prefixes on the link to which the client is connected), or there were no addresses in any of the IAs sent by the client, the server MUST NOT send a reply to the client.
