* interface: minor fix for unnecessary ++ operation.Yousong Zhou2015-05-231-1/+1

* interface: remove redundant iface_attr_info.Yousong Zhou2015-05-231-6/+0
| | | | | | | | BLOBMSG_TYPE_STRING is the default type for elements of BLOBMSG_TYPE_ARRAY. Array type IFACE_ATTR_DNS_SEARCH was already missing there, so drop the whole part anyway. Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>

* netifd: Interface last error supportHans Dedecker2015-04-031-1/+26
| | | | | | | | | | | | | | Adds interface last error support which preserves the last reported error reported by the protocol handler till the interface is up; e.g. survives network reload and interface restarts. This is mainly usefull for tracking down why an interface fails to establish; eg auth failure/traffic limit for PPP interfaces Protocol handlers register last error support by setting lasterror=1 in the proto_init function Signed-off-by: Johan Peeters <johan.peeters111@gmail.com> Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
* netifd:Make sure interface device config is also cachedHans Dedecker2015-03-191-3/+3
| | | | | | | | | | Fixes issue interface device config is not applied in some cases. As the interface device config was applied but not always cached; an interface device config diff was not always detected. Simplify device config setting by exposing as api only device_apply_config Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* netifd: Make interface identifier of delegated IPv6 address configurableHans Dedecker2015-01-191-0/+35
| | | | | | | | | | | | | 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>

| | | | | | | | | | | config state Reinserts the config IP parameters as the config_ip parameter of the new interface is set to false in interface_alloc and thus not loading the config ip options of the old interface Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
* netifd: Fix lost interface device config for devices having default configHans Dedecker2014-10-121-2/+4
| | | | | | | As the PPP main device (either a simple or old style vlan device) is freed when PPP interfaces are reloaded; interface device specific config (eg mtu/macaddr/...) is lost as the interface config is not re-applied on the newly created device. Patch fixes the issue by re-applying the interface device config after the main device is claimed and is having default config. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

| | | | | | | | | | interface_change_config Fixes a regression issue introduced by commit d2a33f3f0fe704e4396fa2ada08401cb955ba7cb for device less protocol handlers. An active interface using a deviceless protocol handler will be be teared down when the interface config is checked upon an update as the interface link and enabled parameters are unset as no underlying device is present (eg tunnel interfaces) Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* netifd: Reload proto on topology changeHelmut Schaa2014-03-211-0/+5
| | | | | | | | | | Introduce a new device event "topology change" that gets signaled by bridges on adding/removing members. On "topology changes" the proto handlers are requested to "renew" which is most useful for DHCP. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com>
* netifd: Check interface autostart parameter when handling interface state ↵Hans Dedecker2014-03-201-1/+1
| | | | | | | | changes Fixes an issue when 2 interfaces make use of the same ifname (device) and one of the interfaces has autostart disabled; bringing up the other interface would also start the interface for which autostart is disabled (link_state and enabled will both be true for the autostart disabled interface and thus a setup will be launched) Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* netifd: Link layer state awareness support on interface levelHans Dedecker2014-02-271-30/+100
| | | | | | | | The link layer state is monitored for a given interface; an interface will be setup when both enabled and link layer active. Likewise an interface will be teared down when either disabled or link layer down. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* netifd: Link layer state support on interface levelHans Dedecker2013-12-081-30/+100
| | | | | | | | | | | Patch implements handling of link layer support on interface level. An interface will go into the setup state when it's enabled and the underlying link state is enabled. Vice versa an interface will go to the down state when it's either disabled or underlying link state is disabled.
