I think we should move away from using the source-ids.
Having a "GSource*" pointer makes it clearer what this is, compared to a
guint source ID. Also, g_source_remove() always needs to first do a hash
lookup (with locking) to resolve the source ID to the GSource. This is
unnecessary.

I got a report of a scenario where multiple servers reply to a REQUEST
in SELECTING, and all servers send NAKs except the one which sent the
offer, which replies with a ACK. In that scenario, n-dhcp4 is not able
to obtain a lease because it restarts from INIT as soon as the first
NAK is received. For comparison, dhclient can get a lease because it
ignores all NAKs in SELECTING.
Arguably, the network is misconfigured there, but it would be great if
n-dhcp4 could still work in such scenario.
According to RFC 2131, ACK and NAK messages from server must contain a
server-id option. The RFC doesn't explicitly say that the client
should check the option, but I think it's a reasonable thing to do, at
least for NAKs.
This patch stores the server-id of the REQUEST in SELECTING, and
compares it with the server-id from NAKs, to discard other servers'
replies.

NMClient is strongly tied to the GMainContext with which it was created.
Several operations must only be called from within the context. There
was an assertion for that.
However, creating (and init_async()) should be allowed to call not
from within the GMainContext. So if the current context has no owner
(is not acquired), then it's also OK.
Fix the assertion for that.

On newer distros, remove the build-time default for settings

(cherry picked from commit bb832641eb)
Currently it is possible to specify a list of default settings plugins
to be used when configuration doesn't contain the main.plugins key.
We want to add a mechanism that allows to automatically load any
plugin found in the plugins directory without needing
configuration. This mechanism is useful when plugins are shipped in a
different, optional subpackage, to automatically use them.
With such mechanism, the actual list of plugins will be determined
(in order of evaluation):
1. via explicit user configuration in /etc, if any
2. via distro configuration in /usr, if any
3. using the build-time default, if any
4. looking for known plugins in /usr/lib
(cherry picked from commit 392daa5dab)
When we have a bridge interface with ports attached externally (that is,
not by NetworkManager itself), then it can make sense that during
checkpoint rollback we want to keep those ports attached.
During rollback, we may need to deactivate the bridge device and
re-activate it. Implement this, by setting a flag before deactivating,
which prevents external ports to be detached. The flag gets cleared,
when the device state changes to activated (the following activation)
or unmanaged.
This is an ugly solution, for several reasons.
For one, NMDevice tracks its ports in the "slaves" list. But what
it does is ugly. There is no clear concept to understand what it
actually tacks. For example, it tracks externally added interfaces
(nm_device_sys_iface_state_is_external()) that are attached while
not being connected. But it also tracks interfaces that we want to attach
during activation (but which are not yet actually enslaved). It also tracks
slaves that have no actual netdev device (OVS). So it's not clear what this
list contains and what it should contain at any point in time. When we skip
the change of the slaves states during nm_device_master_release_slaves_all(),
it's not really clear what the effects are. It's ugly, but probably correct
enough. What would be better, if we had a clear purpose of what the
lists (or several lists) mean. E.g. a list of all ports that are
currently, physically attached vs. a list of ports we want to attach vs.
a list of OVS slaves that have no actual netdev device.
Another problem is that we attach state on the device
("activation_state_preserve_external_ports"), which should linger there
during the deactivation and reactivation. How can we be sure that we don't
leave that flag dangling there, and that the desired following activation
is the one we cared about? If the follow-up activation fails short (e.g. an
unmanaged command comes first), will we properly disconnect the slaves?
Should we even? In practice, it might be correct enough.
Also, we only implement this for bridges. I think this is where it makes
the most sense. And after all, it's an odd thing to preserve unknown,
external things during a rollback -- unknown, because we have no knowledge
about why these ports are attached and what to do with them.
Also, the change doesn't remember the ports that were attached when the
checkpoint was created. Instead, we preserve all ports that are attached
during rollback. That seems more useful and easier to implement. So we
don't actually rollback to the configuration when the checkpoint was
created. Instead, we rollback, but keep external devices.
Also, we do this now by default and introduce a flag to get the previous
behavior.

(cherry picked from commit 98b3056604)
For devices that configure IP by themselves (by returning
"->ready_for_ip_config() = TRUE" and implementing
->act_stage3_ip_config()), we skip manual configuration. Currently,
manual configuration is the only one that sets flag HAS_DNS_PRIORITY
into the resulting l3cd.
So, the merged l3cd for such devices misses a dns-priority and is
ignored by the DNS manager.
Explicitly initialize the priority to 0; in this way, the default
value for the device will be set in the final l3cd during the merge.

(cherry picked from commit 1a1c22e38c)
We can get a platform signal for any number of reasons. In particular,
we can get a signal that the object is present in platform, while the object
is tracked as zombie.
"Zombies" are objects that were actively configured by NetworkManager, but
now no longer and thus will need to be removed. We remember them as objects
that we need to delete.
The assertion was wrong. We don't need to handle the case "in_platform"
and linked in "os_zombie_lst" specially. If we get a signal that the
object exists while being a zombie, that is fine and not something to
handle specially.

The DPDK port will not have a link after the devbind which is needed for

The DPDK port MTU should be set on ovsdb right after the interface is
added to ovsdb. This way the users will be able to set MTU for DPDK
ports and modify it.

Since commit ecc73eb239 ('ovs-port: always remove the OVSDB entry on
slave release'), ovs port were removing the ovsdb entry upon being
un-enslaved, no matter what the reason for un-enslavement was. The idea
was to remove the stale ovsdb entry upon forcible device removal.
This cleanup is specific to OpenVSwitch, since for other device types,
the device master is the property of the slave and thus goes away along
with the device.
Turns out we're now removing the ovsdb entry even when the device
actually doesn't go away, but we're pretending it does because the
daemon is shutting down.
To add insult to injury, we generally end up removing one entry,
because the other ovsdb calls end up in a queue and don't get serviced
before the daemon shuts down. The result is a mess. (This patch
doesn't solve that -- if someone terminates the daemon with in-flight
ovsdb calls they're still out of luck).
Let's do the cleanup now only if the device was actually physically
removed.

Recent meson versions treat unknown options as error and break now the
build. Good from them. This was an oversight.

As we iterate over "self->num_freqs", we must not modify "freqs",
otherwise, the second and subsequenty frequencies in self->freqs[i]
cannot match.

Fixes: ba8527ca58 ('wifi: preliminary nl80211 patch')
(cherry picked from commit 4f9f0587d5)
G-IR currently lacks an annotation for associating async calls to their
_finish counterparts. As a result, vala's binding generator assumes that
corresponding function is just function name - _async + _finish. This
holds true for 99% of the time, but not here, because
nm_device_wifi_request_scan_options_async uses
nm_device_wifi_request_scan_finish instead of expected
nm_device_wifi_request_scan_options_finish (sharing it with
nm_device_wifi_request_scan_async). As such, a metadata entry is
required to point vala to correct finishing function.
