2017-01-05config: respect ignore uci optionJo-Philipp Wich
The odhcpd documentation currently implies that "option ignore 1" in a section of type "dhcp" will disable any services on the referenced interface while the code actually ignores the setting when initializing referenced interfaces. This commonly leads to situations where users think that "option disabled" will prevent any server activity on a given interface while in reality odhcpd effectively acts as rogue DHCPv6 server in its default configuration. To fully inhibit any activity, one has to specify both "option ignore 1" as well as "option ra disabled", "option ndp disabled" and "option dhcpv6 disabled" which is highly counter intuitive at best. A previous commit (5f425ed Respect interface "ignore" settings as documented.) attempted to address the problem by observing the value of i->ignore instead of unconditionally enabling all protocols but broke the ability to use DHCPv6 relay mode while having DHCPv4 disabled. This patch changes ... - the enabling of services on an interface to use the value of the ignore option as default choice instead of hardcoding "true" - the options "ra", "ndp", "dhcpv4" and "dhcpv6" to take precedence over the default "ignore" state to allow selectively enabling services on ignored interfaces - the README to clarify the fact that "ra", "ndp", "dhcpv4" and "dhcpv6" can now override "option ignore" Signed-off-by: Jo-Philipp Wich <jo@mein.io> Acked-by: Karl Palsson <karlp@etactica.com> Tested-by: Stijn Tintel <stijn@linux-ipv6.be> Tested-by: Hans Dedecker <dedeckeh@gmail.com>

2016-12-27Revert "Respect interface "ignore" settings as documented."Stijn Tintel
This reverts commit 5f425ed1e5f92397e27ec4f44820b6ef677b8134. Both dnsmasq and odhcpd use the ignore option. This is fine for normal operation, but it breaks DHCPv6 relay when dnsmasq is disabled on the wan interface. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
2016-12-12config: Fix RA interface config being overwrittenHans Dedecker
In case multiple dhcp uci sections are configured and one section contains RA config while the other section does not; the RA interface config of the first section will be overwritten by the second section. Fix this by setting the default values for ra_management and ndp_proxy_routing uci parameters when the interface is created and by removing the overwrite check Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

2016-11-21config: Support infinite as DHCP pool leasetime valueHans Dedecker
Add support for infinite leasetime value; this can be done by specifying "infinite" as leasetime value which is similar to dnsmasq infinite leasetime support. Specifying "infinite" as leasetime is valid for both the host and dhcp uci sections. A DHCPv4/DHCPv6 assignment is now considered infinite if valid_unil holds the value 0.

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.
