e00475ac8f wifi: don't limit active scans for SSIDs to 5
As far as NMSupplicantInterface is concerned, don't clamp the
max-scan-ssids to 5. We should track the real value that wpa_supplicant
announces, and it's up to the caller to provide fewer SSIDs.

In particular, we want to limit the number of hidden SSIDs that we
accept from connection profiles, but we don't want to limit the number
of active scans via `nmcli device wifi rescan ssid $SSID [...]`.

2eb398648f wifi: add callback to nm_supplicant_interface_request_scan()
While we request a scan, we are not yet actually scanning. That means, the supplicant's
"scanning" property will only change to TRUE a while after we initiate the scan. It may
even never happen.

We thus need to handle that the request is currently pending and react when the
request completes.

80e7e8845a wifi: fix and improve handling of Wi-Fi scanning state
In NMSupplicantInterface, we determine whether we currently are scanning
both on the "scanning" supplicant state and the "Scanning" property.

Extend that. If we currently are scanning and are about to clear the
scanning state, then pretend to still scan as long as we are still
initializing BSS instances. What otherwise happens is that we declare
that we finished scanning, but the NMWifiAP instances are not yet ready.
The result is, that `nmcli device wifi` will already start printing the
scan list, when we didn't yet fully process all access points.

Now, _notify_maybe_scanning() will delay switching the scanning state to
disabled, as long as we have BSS initializing (bss_initializing_lst_head).

Also, ignore the "ScanDone" signal. It's redundant to the "Scanning"
property anyway.

Also, only set priv->last_scan_msec when we switch the scanning state
off. That is the right (and only) place where the last-scan timestamp
needs updating.

b480cda596 supplicant: cleanup notify signals for combined properties in supplicant
Certain properties (for example "scanning") are combined from multiple
other properties. So, we want to notify a changed signal, exactly when
something relevant changes. We also may not want to emit a signal while
we are still in the middle of changing multiple properties together.
Only at certain places we want to check and emit the signal.

Simplify the implementation for that by tracking the property value that
we currently expose, and keeping state about when it changes.

52dbab7d07 all: use nm_clear_pointer() instead of g_clear_pointer()
g_clear_pointer() would always cast the destroy notify function
pointer to GDestroyNotify. That means, it lost some type safety, like

   GPtrArray *ptr_arr = ...

   g_clear_pointer (&ptr_arr, g_array_unref);

Since glib 2.58 ([1]), g_clear_pointer() is also more type safe. But
this is not used by NetworkManager, because we don't set
GLIB_VERSION_MIN_REQUIRED to 2.58.

[1] f9a9902aac

We have nm_clear_pointer() to avoid this issue for a long time (pre
1.12.0). Possibly we should redefine in our source tree g_clear_pointer()
as nm_clear_pointer(). However, I don't like to patch glib functions
with our own variant. Arguably, we do patch g_clear_error() in
such a manner. But there the point is to make the function inlinable.

Also, nm_clear_pointer() returns a boolean that indicates whether
anything was cleared. That is sometimes useful. I think we should
just consistently use nm_clear_pointer() instead, which does always
the preferable thing.

Replace:

   sed 's/\<g_clear_pointer *(\([^;]*\), *\([a-z_A-Z0-9]\+\) *)/nm_clear_pointer (\1, \2)/g' $(git grep -l g_clear_pointer) -i

11797f4ad4 supplicant: fix crash setting supplicant state down
When we receive a "InterfaceRemoved" signal, we will end up calling
set_state_down(). That emits a "state" change signal, which causes
NMDeviceWifi to unref the supplicant interface. This may already
give up the last reference, and we cleanup the supplicant state
(by again calling set_state_down()). When we return, set_state_down()
will crash because it operates on an already destroyed instance.

Avoid that by keeping a reference to the interface during set_state_down().

6c837a366b supplicant: combine multiple log lines about supported supplicant features
For many purposes, the supplicant features are not very interesting (as
they are also mostly static for a certain release/distribution). Combine
the multiple logging lines into one.

Also, sort the NMSupplCapType enum values consistently with the order
in which we log them.

Also, rename the logging output for features to match the enum name.
E.g. "FAST" instead of "EAP-FAST".

Now:

b83f07916a supplicant: large rework of wpa_supplicant handling
Avoid GDBusProxy, instead use GDBusConnection directly. I very much
prefer this because that way we have explicit control over what happens
on D-Bus. With GDBusProxy this is hidden under another layer of complex
code. The hardest part when using a D-Bus interface is to manage the
state via an asynchronous medium. GDBusProxy contains state about the
D-Bus interface and duplicate the state that we track. This makes it hard
to reason about things.

Rework creation of NMSupplicantInterface. Previously, a NMSupplicantInterface
had multiple initialization states. In particular, the first state would not
yet tie the interface to a certain D-Bus object path. Instead, NMSupplicantInterface
would try and retry to create the D-Bus object.
Now, NMSupplicantManager has an asynchronous method to create interface
instances. The manager only creates an interface instance after the D-Bus
path is known. That means, a NMSupplicantInterface instance is now
strongly tied to a name-owner and D-Bus path.

It follows that the state of NMSupplicantInterface can only go from STARTING,
via the supplicant states, to DOWN. Never back. That was already previously
the case that the state from DOWN was final and once the 3 initial
states were passed, the interface's state would never go back to the initial
state. Now this is more strict and more formalized. The 3 initialization states
are combined.

I think the tighter state handling simplifies users of NMSupplicantInterface.
See for example "nm-device-ethernet.c". It's still complicated, because handling
state is fundamentally difficult.

NMSupplicantManager will take care to D-Bus activate wpa_supplicant only
when necessary (poke). Previously, creating the manager instance
would always start suppliant service. Now, it's started on demand.

b15a9b3dc4 supplicant: allocate blobs hash table lazily for supplicant config
It's very unlikely that we have actual blobs for a Wi-Fi network.
That is because the settings plugins (keyfile, ifcfg-rh) convert
blobs to files on disk when writing the profile. So, you can only
have them by editing the files directly to contain blobs.

At that point, don't always create the GHashTable for blobs.

de62da297e all: drop explicit casts from _GET_PRIVATE() macro calls
The _GET_PRIVATE() macros are all implemented based on
_NM_GET_PRIVATE(). That macro tries to be more type safe and uses
_Generic() to do the right thing. Explicitly casting is not only
unnecessary, it defeats these (static) type checks.

Don't do that.

cd31437024 shared: drop _STATIC variant of macros that define functions
Several macros are used to define function. They had a "_STATIC" variant,
to define the function as static.

I think those macros should not try to abstract entirely what they do.
They should not accept the function scope as argument (or have two
variants per scope). This also because it might make sense to add
additional __attribute__(()) to the function. That only works, if
the macro does not pretend to *not* define a plain function.

Instead, embrace what the function does and let the users place the
function scope as they see fit.

This also follows what is already done with

    static NM_CACHED_QUARK_FCN ("autoconnect-root", autoconnect_root_quark)

The signal is unused (and should be removed).

Still, the parameter passed to g_signal_emit() is a C string, not a
GVariant. I think as there are no subscribers, glib wouldn't actually
do anything with the arguments. Though, I am not sure whether glib still
tries to initialize a GValue with a GVariant type, leading to a crash.
