With "wireguard.ip4-auto-default-route" and "wireguard.ip6-auto-default-route",
NetworkManager automatically adds policy routing rules for the default
route.
For that, it needs to pick (up to) two numbers:
- the fwmark. This is used both for WireGuard's fwmark setting and
is also the number of the routing table where the default-route is
added.
- the rule priority. NetworkManager adds two policy routing rules, and
we need to place them somewhere before the default rules (at 32766).
Previously, we looked at exiting platform configuration and picked
numbers that were not yet used. However, during restart of
NetworkManager, we leave the interface up and after restart we will
take over the previous configuration. At that point, we need to choose
the same fwmark/priority, otherwise the configuration changes.
But since we picked numbers that were not yet used, we would always choose
different numbers. For routing rules that meant that after restart a second
pair of rules was added.
We possibly could store this data in the device's state-file. But that
is complex. Instead, just pick numbers deterministically based on the
connection's UUID.
If the picked numbers are not suitable, then the user can still work
around that:
- for fwmark, the user can explicitly configure wireguard.fwmark
setting.
- for the policy routes, the user can explicitly add the rules with
the desired priorirites (arguably, currently the default-route cannot
be added like a regular route, so the table cannot be set. Possibly
the user would have to add two /1 routes instead with
suppress_prefixlength=1).

We call _auto_default_route_init() at various places, for example during
coerce_route_table(). We cannot be sure that we don't call it before
activation starts (before stage1) or after device-cleanup.
That means, upon activation, we need to clear the state first. Do that in
act_stage1_prepare().

Instead of straight-out rejecting extra parameters for various nmcli
sub-commands (such as "nmcli dev status", "nmcli dev wifi rescan" or
"nmcli dev wifi connect", etc.), we just print a warning and go ahead.
This is unhelpful. In case the user makes a typo, we'll do the wrong
thing and possibly even drown the warning in the output.
While at that, let's make the error message consistent. One less string
to translate.

It's criminally ugly. Also -- totally useless.
These functions return NMCResultCode, call_cmd() expects them to do
so, and assigns the return_value itself.

For WireGuard (like for all IP-tunnels and IP-based VPNs), the IP addresses of
the peers must be reached outside the tunnel/VPN itself.
For VPN connections, NetworkManager usually adds a direct /32 route to
the external VPN gateway to the underlying device. For WireGuard that is
not done, because injecting a route to another device is ugly and error
prone. Worse: WireGuard with automatic roaming and multiple peers makes this
more complicated.
This is commonly a problem when setting the default-route via the VPN,
but there are also other subtle setups where special care must be taken
to prevent such routing loops.
WireGuard's wg-quick provides a simple, automatic solution by adding two policy
routing rules and relying on the WireGuard packets having a fwmark set (see [1]).
Let's also do that. Add new properties "wireguard.ip4-auto-default-route"
and "wireguard.ip6-auto-default-route" to enable/disable this. Note that
the default value lets NetworkManager automatically choose whether to
enable it (depending on whether there are any peers that have a default
route). This means, common scenarios should now work well without additional
configuration.
Note that this is also a change in behavior and upon package upgrade
NetworkManager may start adding policy routes (if there are peers that
have a default-route). This is a change in behavior, as the user already
clearly had this setup working and configured some working solution
already.
The new automatism picks the rule priority automatically and adds the
default-route to the routing table that has the same number as the fwmark.
If any of this is unsuitable, then the user is free to disable this
automatism. Note that since 1.18.0 NetworkManager supports policy routing (*).
That means, what this automatism does can be also achieved via explicit
configuration of the profile, which gives the user more flexibility to
adjust all parameters explicitly).
(*) but only since 1.20.0 NetworkManager supports the "suppress_prefixlength"
rule attribute, which makes it impossible to configure exactly this rule-based
solution with 1.18.0 NetworkManager.

NMPlatformObject is a base-type of all actual platform structs.
We very seldomly use this type directly. Most callers that pass
the plobj to nmp_object_new() will need to cast it.
Make the varible a void pointer to not require the cast.

nm_connection_get_setting() returns a pointer of type NMSetting.
That is very inconvenient, because most callers will need the
the result pointer as a setting subtype (like NMSettingConnection).
That would be like g_object_new() returning a "GObject *" pointer,
which is technically correct but annoying.
In the past that problem was avoided by having countless accessors
like nm_connection_get_setting_ip4_config(), etc. But that just blows
up the API and also is not generic. Meaning: the type is not a function
argument but the function itself. That makes composing the code harder
as the setting type cannot be treated generically (as a function argument).
Anyway. Add an internal wrapper that returns a void pointer.

An OVS bridge and its slaves can continue to work even after NM has
quit. Keep the interface enslaved when the @configure argument of
device->release_slave() is FALSE, which happens on quit and in other
circumstances when we don't really want to release the slave from its
master.

To allow completion for mesh connections channel and band need to be
set. This is only done if both values are absent. It does not check
existing values against a given ap_freq. This maybe changed to throw an
error and detect a possible conflict. Any other check is left to verify
step of connection.
This change allows to use ap freq during complete. For tests 0 is passed
as frequency for now. This needs to be changed if completion of freq
should be tested.

an essential feature of 802.11s is to allow moving/mobile mesh points
and adapt the topology dynamically. This includes starting a mesh point
not in range of others and establish the connection once it comes into
range. At the moment for this reason a mesh connection requires the
frequency to be fixed as supplicant does too.
