2016-09-14interface-ip: DNS name server sorting support in resolv.conf.autoHans Dedecker
Interface name servers when being written to resolv.conf.auto are sorted based on the following parameters: -Primary sorting key is interface dns_metric; name servers having lowest interface dns_metric are listed first -Secondary sorting key is interface metric; in case of equal interface dns_metric name servers having lowest interface metric are listed first -Finally alphabetical order of the interface names in case of equal interface dns_metric and metric In case the resolver queries the multiple servers in the order listed; sorting is usefull in the following scenarios : -Name resolving over a main and backup interface -Assign priority to IPv6 name servers over IPv4 or vice versa Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
2016-08-11Prevent premature device free in interface_claim_deviceFelix Fietkau
interface_set_device_config can trigger a device free (for example if the device is here only present in a bridge), which renders dev invalid and leads to segfault. Add a lock to prevent this and clean-up the code for readability.

2016-08-11proto-shell: Support teardown on layer 3 link lossHans Dedecker
Commit c6858766 added interface teardown support on layer 3 device link loss mainly for shell protocols who have no proto task like xl2tp. However for shell protocols having a proto task it is not always the correct action to teardown the interface; as an example the PPP daemon can be put into persist state trying to re-establish the link via a hold-off mechanism if layer 3 link loss is detected. Therefore shell handlers can enable via TEARDOWN_ON_L3_LINK_DOWN a proto flag which will teardown the interface when layer 3 link loss is detected Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

2015-05-23interface: teardown on l3_dev link lost.Yousong Zhou
This is mainly for shell protocols that has no_proto_task so that we can still teardown and setup the interface on l3_dev link lost instead of depending on running state of proto_task. Also rename related callbacks for better clarification. Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>

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>

2015-04-03netifd: Interface last error supportHans Dedecker
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>
2015-03-19netifd:Make sure interface device config is also cachedHans Dedecker
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>

2015-01-19netifd: Make interface identifier of delegated IPv6 address configurableHans Dedecker
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>
2014-10-12netifd: Fix lost interface device config for devices having default configHans Dedecker
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.

2014-03-20netifd: Check interface autostart parameter when handling interface state ↵Hans Dedecker
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>
