[systemd-devel] [PATCH v4] Added support for Uplink Failure Detection using BindCarrier

[Alin Rauta]

Hi,

I've creating patch v4 after addressing your comments.

I provided two APIs for networkctl command:
1. int sd_network_link_get_carrier_bound_to(int ifindex, char ***carriers);
2. int sd_network_link_get_carrier_bound_by(int ifindex, char ***carriers);

This way, only few changes were needed in "networkctl".

Only the "bound_by" links (uplinks) are monitored.
The "bound_by" map is evaluated only when the carrier is lost or gained.

When a link is added, its "bound_by" & "bound_to" maps are created.

When a link is dropped, both maps are removed.
When a link is readded, the maps are created again.

When a link is renamed, the old "bound_by" & "bound_to" maps are removed
and new ones are created taking into account the new name.

Let me know what you think,
Alin
