a685ec45dd device: fix reapplying changes to connection ID and UUID
4 properties are not really relevant for an already activated connection
or it makes not sense to change them. These are connection.id, connection.uuid,
connection.autoconnect and connection.stable-id.

For convenience, we allow to reapply these. This way, one can take
a different setting (e.g. with a different connection.id or
connection.uuid) and reapply them, but such changes are silently
ignored.

However this was done wrongly. Instead of reverting the change to the new
applied connection, we would change the input connection.

This is bad, for example with

  nmcli connection up uuid cb922f18-e99a-49c6-b200-1678b5070a82
  nmcli connection modify cb922f18-e99a-49c6-b200-1678b5070a82 con-name "bogus"
  nmcli device reapply eth0

the last re-apply would reset the settings-connection's connection ID to
what was before, while accepting the new name on the applied-connection
(while it should have been rejected).

Fixes: bf3b3d444c ('device: avoid changing immutable properties during reapply')

238fc87298 device: fail DHCPv6 if a link-local address is not present
Instead of throwing an assertion, fail DHCPv6 when a IPv6 link-local
address is not configured on the device. There are different reasons
why the assertion may fail: for example the address was removed
externally; or the device is gone (and thus the platform already
received the notification of addresses removal) but the device is still
connecting because its disposal happens in an idle callback.

None of these deserves an assertion, which should only be for
programming errors.

e107d0917b device/wifi: silence some logging for AP changes
We log updates of the Wi-Fi AP with a separate logging domain LOGD_WIFI_SCAN.
However, there is ony "update" message that is triggered every 6 seconds, which
becomes especially verbose.

Suppress this one and only log it when compiled --with-more-logging. And then
only log with level LOGL_TRACE, so the user still can filter this one out.

4bf493fcaf device: add get_autoconnect_allowed() virtual function
It allows derived classes to override the autoconnect-allowed
state.

We already have

- NM_DEVICE_AUTOCONNECT property, which is two parts:
  - NMDevicePrivate::autoconnect_user, which is settable via
    D-Bus by the use, to allow the device to autoconnect.
  - NMDevicePrivate::autoconnect_intern, which is set by
    internal decision.
- NM_DEVICE_AUTOCONNECT_ALLOWED signal, where other devices can
  subscribe to block autoconnect. Currently that is only used
  by NMDeviceOlpcMesh.

These two make up for nm_device_autoconnect_allowed().

Add another way to allow derived classes to disable autoconnect
temporarily. This could also be achieved by having the device
subscribe to NM_DEVICE_AUTOCONNECT_ALLOWED of self, or by adding
a signal slot. But a plain function pointer seems easier.

da37c8ac6c device: separately handle NMDevice's autoconnect by user and internal decision
The NMDevice's autoconnect property is settable via D-Bus and is is
also modified by internal decision, like when no PIN is available.

Certain internal actions cause clearing the internal autoconnect flag,
but they should not override the user desicion.

For example, when NM awaks from sleep it would reenable autoconnect,
but it should not reenable it for devices where the user explicitly
said that autoconnect is to be disabled.

Similarly, activating a device alone is not yet an instruction to
re-enable autoconnect. If the user consciously disables autoconnect,
it should stay enabled. On the other hand, activating a device should
reenable autoconnect if it was blocked by internal decision.

We need to track these two flags separately, and set them accordingly.

7f7bed4736 wifi: only react on AP update signal when there are actual changes
Since we emit BSS_UPDATED signal before SCAN_DONE, it is very likely
that nothing actually changed. This clutters the logs with update
messages.

Also move the added/removed logging messages inside ap_add_remove().
We would call ap_add_remove() at several places without logging the
change.

13b17d44dc wifi: check for invalid BSSID in nm_wifi_ap_update_from_properties()
In nm_wifi_ap_new_from_properties(), we checked that the BSSID is valid
and bailed out otherwise. Since we call nm_wifi_ap_update_from_properties()
on a created BSSID, we should ensure there too that an update does not cause
the address to become invalid.

In the unlikely case where an update would change a previously valid address
to an invalid one, we would ignore the update.

Thus, move the check for addresses inside nm_wifi_ap_update_from_properties().

c961c36c8f supplicant: merge NEW_BSS signal with BSS_UPDATED
Before, the NEW_BSS signal was not careful to emit the signal only when the BSS
is seen for the first time. Consequently, supplicant_iface_new_bss_cb() checked
whether it already knows about the new BSS.

Merge NEW_BSS and BSS_UPDATED. Now we emit BSS_UPDATED when either the
BSS is new or changed.

Also, in supplicant_iface_new_bss_cb() (now supplicant_iface_bss_updated_cb())
no longer constructs an @ap instance if we have a @found_ap.

In some situations there can be a value of having a separate ADD signal.
But only when there the consumers care, and if the consumers can trust that
ADD is not just an UPDATE. The only consumer doesn't care and it not not be
trusted, so merge the signals.

2735e614b7 supplicant: rework nm_supplicant_interface_set_config() to invoke result callback
Instead of having a NM_SUPPLICANT_INTERFACE_CONNECTION_ERROR signal to notify
about failures during AddNetwork/SelectNetwork, accept a callback to report
success/failure.

Thereby, rename nm_supplicant_interface_set_config() to
nm_supplicant_interface_assoc().

The async callback is guaranteed to:

 - be invoked exactly once, signalling success or failure
 - always being invoked asyncronously.

The pending request can be (synchronously) cancelled via
nm_supplicant_interface_disconnect() or by disposing the
interface instance. In those cases the callback will be invoked
too, with error code cancelled/disposing.

f9c95bdd23 device/wifi: cache GObject property "scanning"
Cache the value for accessing the GObject property
NM_DEVICE_WIFI_SCANNING.

Re-evaluating the property every time by checking the
supplicant interface is ugly because it might change
under the hood. It should only change if (and only if)
we emit a notify changed signal.

Also, avoid accessing
  nm_supplicant_interface_get_scanning (priv->sup_iface)
without checking whether priv->sup_iface is not NULL.

36196b5a82 device/wifi: refactor logging of Wi-Fi AP by preserving logging context of device

Replace nm_wifi_ap_dump() by nm_wifi_ap_to_string() and let device
log a message about the AP.

Also, update the format for printing the AP. Now, all fields are
separated by space.

8b455abab2 device: cleanup handling queued state change in NMDevice
- no longer bother clearing .state and .reason when the .id
  field is unset. The fields just don't matter and no user
  accesses these fields when the glib source id is not set.
- unify logging and give them all a prefix "queue-state[%s, %s, %u]: ".
- drop nm_device_queued_state_peek(), it only had one caller,
  thus inline the trivial check.
- make nm_device_queued_state_clear() a static function
  queued_state_clear()
- rename queued_set_state() to queued_state_set().

146f2c0bd1 device: track exported-object path for NMActRequest from device
The public property NM_DEVICE_ACTIVATION_REQUEST exposes the exported
D-Bus path. So, it's not sufficient to emit property changed signals
when changing the priv->act_request pointer, we must also react on
exporting/unexporting.

It's not clear whether this fixes an actual bug. Maybe, we never
export/unexport priv->act_request while the device tracks it.
But the code is pretty hard to follow and it's hard to verify
whether this is the case.
By hooking up to "notify::path", we can easily verify that such
a situtation cannot arise.

ba1cc6a288 core: refactor evaluation of device's match-spec
Previously, we would have different functions like
  - nm_match_spec_device_type()
  - nm_match_spec_hwaddr()
  - nm_match_spec_s390_subchannels()
  - nm_match_spec_interface_name()
which all would handle one type of match-spec.

So, to get the overall result whether the arguments
match or not, nm_device_spec_match_list() had to stich
them together and iterate the list multiple times.

Refactor the code to have one nm_match_spec_device()
function that gets all relevant paramters.

The upside is:

  - the logic how to evaluate the match-spec is all at one place
    (match_device_eval()) instead of spread over multiple
    functions.

  - It requires iterating the list at most twice. Twice, because
    we do a fast pre-search for "*".

One downside could be, that we have to pass all 4 arguments
for the evaluation, even if the might no be needed. That is,
because "nm-core-utils.c" shall be independend from NMDevice, it
cannot receive a device instance to get the parameters as needed.
As we would add new match-types, the argument list would grow.
However, all arguments are cached and fetching them from the
device's private data is very cheap.

2e8af781c5 device: don't call _commit_mtu() when ipv4.method=disabled
After commit 553717bb1c ("device: don't set ip4_state=IP_FAIL for
ipv4.method=disabled"), we commit an empty IPv4 configuration when
IPv4 is disabled. This means that it's not necessary anymore to call
_commit_mtu() because the MTU will be set in
ip4_config_merge_and_apply().

303a65b4dd vlan: use parent interface mtu as default
After commit 22e8af6242 ("device: set a per-device default MTU on
activation") we explicitly set the VLAN MTU to 1500 if not overridden
by user settings. This has the advantage that the MTU is set to a
predictable value, while before it could have different values
depending on when the interface was created (for example, the
interface would get a 1500 MTU if created during boot, or would
inherit the parent's MTU if activated manually).

However, a better default value is the MTU of the parent interface
which is in most cases what the user wants. This value was the default
before commit 22e8af6242 for manually activated connections.
