This rewrites the MAC address generation logic to distinguish between
MAC addresses assigned to a wireless interface or virtual / wired
interfaces.
Each radio is now assigned a range of SSIDs, allowing for up to 8 SSIDs
per radio. Previosuly, there were 8 MAC addresses total for the entire
device.
To keep compatibility on already deployed nodes, MAC addresses for wired
/ virtual interfaces stay unchanged.
This change is required to support nodes with more than 2 radios.
It also allows us to increase the number of VAPs per radio.
We now keep the VPN enable state, bandwidth limit enable and actual limits
in the core config to avoid having to recover "user intent" from different
config files when the used VPN packages change.
Fixes#1736
gluon-wan is a sudo-like exec wrapper that switches the process group to
gluon-mesh-vpn, making it use the WAN dnsmasq rather than resolving over
the mesh.
Note that this only affects DNS at the moment. Processes running under
gluon-wan will still use the regular mesh IPv6 routing table, and not the
WAN routing table. This is not a problem for IPv4, as there is only one
IPv4 routing table.
Fixes#1575
The generic upgrade script is moved to run after the more specific scripts.
In addition, the script will now remove the configuration sections of
uninstalled VPN packages, so both positive and negative changes of the
default enable state can be migrated correctly.
