Network Cost [1] is a vendor-specific information element defined by
Microsoft and used to advertise the cost of Wi-Fi networks to clients.
We can use it together with the ANDROID_METERED mechanism to
automatically set the metered flag on the device.

There's multiple things wrong there, but unnoticed because the error handling
was entirely missing or nobody is using thie anymore.
The Mesh ID needs to be set while the device is down. Also, the channel
needs to be set last, because that's what triggers the connection
attempt. For that the device needs to be up.
Also, fix the error handling.

The comment is wrong. Since 6eaded9071fb ('device: add
get_autoconnect_allowed() virtual function'), get_autoconnect_allowed()
is called before the device state is consulted.

gtkdoc-scan supports regular expressions in the --ignore-decorators
command-line option. Since it is easier to use a regexp than grepping
macros from a source file, revert the ugly solution from commit
2d941dc95a1d ('build: fix errors when building with gtk-doc 1.32').

Use the same format of systemd-netword, so that we will be compatible
with the leases created/read by the current "internal" plugin.
Note that actually only the leased address is processed when reading a
lease file, so no need to save more than the ip address when saving the
lease.

For each plugin we try to come up with a lease file constructed in the
same way, i.e., plugin name + iface + connection duid. If the file isn't
already there, for some plugins (dhclient) we do extra checks in order
to allow to use lease files generated outside of NetworkManager. Let's
allow to generate the common NetworkManager dhcp lease file name in a
shared function, reporting to the caller if the file isn't already there,
so that further plugin specific checks can be performed if needed.

gtkdoc-scan 1.32 performs stricter checks on structures definitions
and so it complains on:

GObject parent;
} NMVpnPluginOld NM_DEPRECATED_IN_1_2;

These are deprecated. Also, they are nowadays implemented as macros
that expand to
#define g_main_run(loop) g_main_loop_run(loop) GLIB_DEPRECATED_MACRO_IN_2_26_FOR(g_main_loop_run)
This can cause compilation failure (in some environments).

system_create_virtual_device() first creates the device (unrealized)
and then, if there a connection for the device with autoconnect=yes,
creates the backing resources. If this last step fails the device
should continue to exist, even if in an unrealized state.

When the master AC becomes ready, activate_stage1_device_prepare() is
called in a idle handler. If the master AC fails in the meantime, it
will change state to deactivating or deactivated. We must check for
that condition before proceeding with slave activation. Note the the
'master_ready' flag of an AC is never cleared after it is set.

With accept_ra set to 1, kernel sends its own router solicitation
messages and parses the advertisements. This duplicates what NM
already does in userspace and has unwanted consequences like [1] and
[2].
The only reason why accept_ra was re-enabled in the past was to apply
RA parameters like ReachableTime and RetransTimer [3]; but now NM
supports them and so accept_ra can be turned off again.
Also, note that previously the option was set in
addrconf6_start_with_link_ready(), and so this was done only when the
method was 'auto'. Instead, now we clear it for all methods except
'ignore'.

IPv6 router advertisement messages contain the following parameters
(RFC 4861):
- Reachable time: 32-bit unsigned integer. The time, in
milliseconds, that a node assumes a neighbor is reachable after
having received a reachability confirmation. Used by the Neighbor
Unreachability Detection algorithm. A value of zero means
unspecified (by this router).
- Retrans Timer: 32-bit unsigned integer. The time, in milliseconds,
between retransmitted Neighbor Solicitation messages. Used by
address resolution and the Neighbor Unreachability Detection
algorithm. A value of zero means unspecified (by this router).
Currently NM ignores them; however, since it leaves accept_ra=1, the
kernel parses RAs and applies those parameters for us [1].
In the next commit kernel handling of RAs will be disabled, so let NM
set those neighbor-related parameters.

nm_device_activate_schedule_stage2_device_config() to end of stage1
Note that by now no callers of nm_device_activate_schedule_stage2_device_config()
are left. All previous callers now re-schedule stage1 instead of directly
scheduling stage2.
Note that if stage2 later also gets re-factored to re-enter itself
instead of scheduling stage3 right away, the function will be used
again.
That means, we can move the check for the master where it belongs: as
part (and at the end of) stage1.
Also, slightly simplify the code. The handler master_ready_cb()
no longer directly calls master_ready(). It's enough to always
enter stage1 again.
Also drop master_ready_handled. We don't need to remember that this
condition was satsified. We can just check it always when we reach
the place in activate_stage1_device_prepare().

I am about to change the when stage1 gets postponed, then the way to
proceed it is to schedule stage1 again (instead of scheduling stage2).
The reason is that stage1 handling should be reentrant and we should
keep entering it until there is no more reason to postpone it. If
a subclass postpones stage1 and then later progresses it by directly
scheduling stage2, then only the subclass is in control over postponing
stage 2.
Instead, anybody should be able to delay stage2 independently. That can
only work if everybody signals readyness to proceed by scheduling stage1
again.

for NMDeviceEthernet
There is a small change in the order of actions. Now we set the MAC address before

NMDevice's act_stage1_prepare() now does nothing. Calling it is not
useful and has no effect.
In general, when a subclass overwrites a virtual function, it must be
defined whether the subclass must, may or must-not call the parents
implementation. Likewise, it must be clear when the parents
implementation should be chained: first, as last, does it matter?
In any case, that very much depends on how the parent is implemented
and this can only be solved by documentation and common conventions.
It's a forgiving approach to have a parents implementation do nothing,
then the subclass may call it at any time (or not call it at all).
This is especially useful if classes don't know their parent class well.
But in NetworkManager code the relationship between classes are known
at compile time, so every of these classes knows it derives directly
from NMDevice.
This forgingin approach was what NMDevice's act_stage1_prepare() was doing.
However, it also adds lines of code resulting in a different kind of complexity.
So, it's not clear that this forgiving approach is really better. Note
that it also has a (tiny) runtime and code-size overhead.
Change the expectation of how NMDevice's act_stage1_prepare() should be
called: it is no longer implemented, and subclasses *MUST* not chain up.

Note that all subclasses of NMDevice that implement act_stage1_prepare(), call
the parents implementation as very first thing.
Previously, NMDevice's act_stage1_prepare() was setting up SR-IOV. But that is
problemantic. Note that it may have returned NM_ACT_STAGE_RETURN_POSTPONE, in which
case subclasses would just skip their action and return to the caller. Later,
sriov_params_cb() would directly call nm_device_activate_schedule_stage2_device_config(),
and thus act_stage1_prepare() was never executed for the subclass. That
is wrong.
First, I don't think it is good to let subclasses decide whether to call a
parents implementation (and when). It just causes ambiguity. In
the best case we do it always in the same order, in the worst case we
call the parent at the wrong time or never. Instead, we want to initialize
SR-IOV always and early in stage1, so we should just do it directly from
activate_stage1_device_prepare(). Now NMDevice's act_stage1_prepare() does
nothing.
The bigger problem is that when a device wants to resume a stage that
it previously postponed, that it would schedule the next stage!
Instead, it should schedule the same stage again instead. That allows
to postpone the completion of a stage for multiple reasons, and each
call to a certain stage merely notifies that something changed and
we need to check whether we can now complete the stage.
For that to work, stages must become re-entrant. That means we need to
remember whether an action that we care about needs to be started, is pending
or already completed.
Compare this to nm_device_activate_schedule_stage3_ip_config_start(),
which checks whether firewall is configured. That is likewise the wrong
approach. Callers that were in stage2 and postponed stage2, and later would
schedule stage3 when they are ready.
Then nm_device_activate_schedule_stage3_ip_config_start() would check whether
firewall is also ready, and do nothing if that's not the case (relying
that when the firewall code completes to call
nm_device_activate_schedule_stage3_ip_config_start().

The only change in behavior is in act_stage1_prepare().
That changes compared to before that we also set the specific
object path if it was already set (and we looked up the AP by
specific object to start with).
Also, for existing APs that we found with nm_wifi_aps_find_first_compatible(),
it changes the order of calling set_current_ap() before nm_active_connection_set_specific_object().
That should not make a different though. I anyway wonder why we even bother to
set the specific object on the AC. Maybe that should be revisited.
