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.
(cherry picked from commit c9dc0eba65)
We initialize the BSS asyncronously. Don't declare SCAN_DONE
until all BSS are up.
Otherwise, especially during the very first scan we declare SCAN_DONE
when having no BSS yet. This wrongly removes the pending action
"wifi-scan", while "autoconnect" cannot happen as there are not BSS
yet. Thus we declare "startup-complete" too early.
Another issue is that we may start autoconnecting with an incomplete
scan list, and thus pick a non-preferred connections.

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().
(cherry picked from commit e3a489180b)
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.

If the assoc-request is cancelled while an "AddNetwork" request is
pending, we must cleanup the added network when the request succeeds.
The issue can also happen when NetworkManager shuts down and exits
the mainloop. This scenario is unsolved as the cleanup action
"RemoveNetwork" has no chance to run.
"AddBlob" works differently in that blogs are added with a specific name,
not like "AddNetwork", where a new D-Bus path is created. Maybe we should
also cleanup blobs that were added by us, but currently we don't.
(cherry picked from commit c47026715e)
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.
(cherry picked from commit 66c45d0fdc)
Also change the signature of the NM_SUPPLICANT_INTERFACE_STATE signal,
to have three "int" type arguments. Thereby also fix the subscribers
to this signal that wrongly had type guint32, instead of guint
(which happens to be the same underlying type, so no real problem).

(cherry picked from commit 5a03de7051)
After commit 2049e97d9e ("dhcp: refactor parsing of 'request' and
'also request' options") NM parses all the existing 'request' and
'also request' from the original configuration file and appends them
as 'also request' to avoid duplicates and conflicts.
So if the original file contains 'request x' (which means "request
only option x instead of builtin defaults"), we would translate it
into 'also request x', which appends the option to the builtin
defaults, causing duplicates in the DHCP request as dhclient seems not
smart enough to sanitize the list by itself.
To fix this, ensure that the request list is reset if the
configuration file contains a 'request'.

scan_request_cb() handles the answer from the D-Bus "Scan" method.
At that point, the scan is not yet done, it merely started. It is
wrong to already signal SCAN_DONE.
The only place where we want to signal SCAN_DONE is when we actually
receive the "ScanDone" D-Bus signal.
(cherry picked from commit 75356841fb)
In the SCAN_DONE handler, NMDeviceWifi resets the flag that indicates
that a current scan request is pending. We need to first obtain the
new APs (NEW_BSS) before signalling SCAN_DONE.
(cherry picked from commit 40a4cc5b2d)
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.
(cherry picked from commit 4e84472b47)
When we dump a list of APs, determine one timestamp for "now",
instead of re-evaluating it every time.
This ensures that all APs are printed with the same understanding
of the current timestamp.
(cherry picked from commit 5e4d13271c)
LOGD_WIFI_SCAN is there to avoid flodding the log with continous scan
results. It should not be used for messages related to scheduling scan
requests.
This is especially important, because LOGD_WIFI_SCAN domain is not
included in LOGD_DEFAULT.
(cherry picked from commit d5657d003c)
The _LOGD() macros of NMDeviceWifi print a logging context for each
line, that is, they add a prefix with the device name.
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.
(cherry picked from commit d98fa31ddd)
- 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().

Reorder code to be like in other source files:
- first includes and generic defines
- then various helper structs
- then GObject related declarations, with first signal and property
enums, then the private data, then the G_DEFINE_TYPE() itself.
- finally, forward declarations for functions.

We don't want to waste a full "int" size to store the @hw_addr_type
in NMDevicePrivate. Previously, that was hacked around by using guint8.
Now, instead use a bitfield which has the right type.
(cherry picked from commit cac0738723)
These two structs are only used at exactly one place: as the type
for a field in NMDevicePrivate.
Having additional structs (that are only used at one place) only
add noise. Also, there are already prior-acts of using unnamed
structs in NMDevicePrivate in case of structs that only serve
to group/namespace a set of fields.

All callers either use a static @action argument or keep a clone

save cloning the string.

While we still recheck-available, we want to queue a pending action to block
startup-complete. However, we have to queue that before removing the pending
action for "wait for supplicant".
<debug> [...] device[0x563abbcca400] (wlp2s0): remove_pending_action (0): 'waiting for supplicant'
<info> [...] manager: startup complete
<debug> [...] device[0x563abbcca400] (wlp2s0): add_pending_action (1): 'queued state change to disconnected'
(cherry picked from commit 252e95c113)
Startup-complete means that all devices have settled in a state
and no further activation is pending. When we have a recheck-available
scheduled, we clearly should not yet declare startup-complete.
Add a new pending-action "recheck-available" to avoid:
<info> [1485520408.3920] device (wlp2s0): supplicant interface state: starting -> ready
<debug> [1485520408.3920] device[0x563abbcca400] (wlp2s0): remove_pending_action (0): 'waiting for supplicant'
<info> [1485520408.3920] manager: startup complete

grep-ing for '\<scanning\>' yields 42 hits under src. But only 2 are actual

ip4_addr_subnets_is_secondary() should fill the list of addresses in

We no longer use wpa_supplicant for MAC address randomization. Instead, NetworkManager
handles it on it's own. It is actually important that supplicant does not interfere
when setting the MAC address of the device.
The code was only in effect when supplicant has a PreassocMacAddr property.
As this is a recent feature, the left-over code wasn't noticed until now.

With commit 4f6c91d696, we aimed to
enable mac-address-randomization by default for Wi-Fi. That however
is not possible by default because it breaks various scenarios.
Also, later wifi.mac-address-randomization was deprecated in favor
of wifi.cloned-mac-address setting.
Both wifi.mac-address-randomization and wifi.cloned-mac-address support
global default values, so it is wrong to read a missing
MAC_ADDRESS_RANDOMIZATION setting as "NEVER" -- which due to
normalization also results in cloned-mac-address=permanent.
See also commit 46d53e1101 which does
something similar for keyfile.
This bug also prevents a user from clearing the cloned-mac-address:
$ nmcli connection show "$CONN"
...
802-11-wireless.cloned-mac-address: permanent
802-11-wireless.mac-address-randomization: never
...
$ nmcli connection modify "$CONN: wifi.cloned-mac-address ''
# ^ takes no effect
As workaround, you also need to clear mac-address-randomization:
$ nmcli connection modify "$CONN: wifi.cloned-mac-address '' \
wifi.mac-address-randomization default

(cherry picked from commit 27cba47957)
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.

If a slave device activates, we should keep the master up even though it
was taken over before.
This fixes an issue, where a single slave to a master would be
reactivated after a daemon restart. The daemon restart would cause the
master to be treated externally created (would go unmanaged when all the
slaves are gone) while the reactivation would leave the master without
slaves for a while.
