2018-08-14device: gracefully handle device names exceeding IFNAMESIZHans Dedecker
Instead of truncating the device name when it exceeds IFNAMSIZ length; let device_set_ifname return an error code and do not add the device to the device list. This avoids possible issues with device names becoming identical due the truncation and as a result unexpected behavior. Further let the different device types gracefully handle the error code returned by device_init Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
2018-07-11replace fall throughs in switch/cases where possible with simple code changesAlexander Couzens
fall throughs are usually error-prone, especially when someone else extend it. Signed-off-by: Alexander Couzens <lynxis@fe80.eu> Acked-by: Hans Dedecker <dedeckeh@gmail.com>
2016-09-26device: Move the different device type registrations to the device type fileHans Dedecker
While at it; make device_types static if only used in the device type file Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

2016-06-29alias: Set alias link device status to disabled when device is removedHans Dedecker
Fixes missing link state event propagation for an aliased device in case a new device is added as the link state has the last known status of the old device possible resulting into no link state change detection.

2016-06-06device: Fix device find failure in avl list due to device name changeHans Dedecker
As device name is used as key in avl list a device name change will break the avl find logic. Function device_set_ifname offers api to set the device name and re-inserts the avl node in the list when the avl key value is changed. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
2016-03-31alias : Fix interface aliased on top of a static interface not getting activeHans Dedecker
An interfaces referring to a static interface is not getting active when doing a network reload or ifup. The problem is triggered by alias_set_device which is not clearing the pending update (mostly a null device due to the previous down event) when the same device is set as the current device via alias_notify_device. As a result alias_set_device_state when called will overwrite the device with an invalid pending device meaning the interface will not be set available anymore and thus will stay down.

2014-02-27netifd: Link layer state awareness support on interface levelHans Dedecker
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>
