* interface-ip: Fix broadcast address when using /31 or /32 IPv4 addressingBaptiste Jonglez2015-09-261-5/+11
| | | | | | | | | | | | A /31-addressed interface requires a broadcast address of 255.255.255.255, because there is no room for a proper broadcast address. Without this, any packet destinated to the other end of the link is sent as broadcast, which is incorrect. For consistency with the Linux kernel, /32-addressed interfaces are treated in the same way.

* netifd: Prevent flapping IPv6 routesKristian Evensen2015-09-211-1/+1
| | | | | | | | | | | | | | Comparing valid_until will always return false as the value is updated for each route update message. This causes IPv6 routes to jump more around than House of Pain, which might have undesirable consequences for user-space and user-space applications. Removing the valid_until comparison when setting keep fixes this problem, and seems to have no side-effects. I am no IPv6 expert, but I see that valid of the route is updated correctly and route is deleted if I block the route update messages. Signed-off-by: Kristian Evensen <kristian.evensen@gmail.com>
* interface-ip: Set route table when enabling interface ip settingsHans Dedecker2015-09-101-0/+9

* netifd: Make interface identifier of delegated IPv6 address configurableHans Dedecker2015-01-191-3/+63
| | | | | | | | | | | | | The ip6ifaceid UCI interface parameter makes the interface identifier of the delegated IPv6 address configurable. The parameter can have the following values: eui64 : Interface identifier is generated from the interface's MAC address random : Interface identifier is generated randomly fixed value : Interface identifier is a fixed value (eg ::1:2) The latter is the default value with a fixed value of ::1 for backwards compatibility Signed-off-by: Hans Dedecker <dedeckeh@gmail.com> Signed-off-by: Joeri Barbarien <joeri.barbarien@gmail.com>

* interface: don't store table id in route if the default table is usedSteven Barth2014-06-201-0/+4
| | | | | | | | | | | Use system_is_default_rt_table() to test whether the resolved routing table is the default one, in this case do not apply the table attribute to the route object. This is needed for backwards compatibility - only routes using a non-default table shall report it in the ifstatus output. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>
* netifd: Route type supportHans Dedecker2014-06-181-2/+12
| | | | | | | | Patch adds route type support in netifd by means of the route parameter type. By default the route type was unicast; the parameter adss support for local/broadcast/multicast/unicast routes which will be put into the appropriate routing table. If route type parameter is unset the route type will be unicast as before. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* netifd: Set prefix assignment enabled if the prefix adress can be installedHans Dedecker2014-04-241-2/+2
| | | | | | | No need to install policy routes if the prefix address cannot be installed; clean up of the policy routes and the prefix address only needs to happen when the prefix assignment was active. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
* netifd: fix IPv6 Link-local DNS serverUlrich Weber2014-04-241-4/+8

* netifd: Assign interface metric to route metric when route is createdHans Dedecker2014-03-111-4/+2
| | | | | | | Interface metric needs to be assigned to the route metric parameter at route creation time. Otherwise if the interface metric is different from 0 route_cmp will wrongly conclude the routes are different. In this case the route will be added/deleted and could end up with the route missing in the kernel depending on the add/delete order. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
