b40a3aa727 gitlab-ci: add building on Fedora 31
And don't build Fedora 28 by default. It's aleady end of life.
But for now keep it, so it can be triggered manually.

7c7ad97831 build/meson: use python3 interpreter for "generate-setting-docs.py"
Fedora 32 drops "python" from the path. Hence "/usr/bin/env python" won't
work anymore. Of course, who needs a way to invoke the interpreter that works
accross different distributions! WTF.

In this case, easy to work around. We run it from meson, so we have access to
the Python 3 binary. Just call python explicitly, like we do with autotools.

9fc4490513 contrib/rpm: drop BuildRequires to deprecated "wireless-tools-devel"
"wireless-tools-devel" is long depreacted and not used by
NetworkManager, not even for WEXT.

Drop it from the build dependencies.

1a2a5b37b4 tests: don't install unnecessary package in gitlab-ci tests
REQUIRED_PACKAGES has two uses:

 - to setup a system for developing NetworkManager. This installs
   convenience packages like "cscope".

 - to install the packages required for unit testing in gitlab-ci.

For gitlab-ci we should only install the packages that we actually
need.

185567559c tests: fix failure installing non-existing packages in REQUIRED_PACKAGES
Previously, dnf/yum used to ignore packages that didn't exist.
In Fedora 32, dnf starts to fail the entire command:

  No match for argument: python-gobject-base
  Error: Unable to find a match: python-gobject-base

Since this script is supposed to work with different RHEL/Fedora
versions, it's expected that not all packages are available everywhere.

Fix that, by installing packages that we know that they might be missing
one by one (and ignore the error).

43b7e66948 settings: fix updating agent-owned VPN secrets
property_to_dbus() returns NULL when called with
NM_CONNECTION_SERIALIZE_WITH_SECRETS_AGENT_OWNED and the property is
not an agent-owned secrets. The function doesn't handle VPN secrets
correctly, since they are all stored as a hash in the vpn.secrets
property and the flag for each of them is a matching '*-flags' key in
the vpn.data property. VPN secrets must be handled differently; do it
in the VPN setting to_dbus_fcn() function.

Fixes: 71928a3e5c ('settings: avoid cloning the connection to maintain agent-owned secrets')

87680c4148 dhcp/nettools: round time difference when calculating the lease lifetime
nettools does not expose the original lease lifetime. It's a missing
API. Instead, it only exposes the timestamp when the lease will expire.

As a workaround, we calulate the timestamp by subtracting the current
timestamp from the expiration timestamp, assuming that the lease was
received just now. However, it was not received *exactly* now, but a
few milliseconds before. Hence, the calculated timestamp is not exact
here and likely a few milliseconds less then the actual (full integer)
value.

Account for that by rounding the value to the second.

4b1cb404fd contrib/rpm: "Suggest" wpa_supplicant for NetworkManager-wifi package
"NetworkManager-wifi" package requires either wpa_supplicant or iwd.
When installing the package without explicitly installing supplicant
or iwd (and not having it installed yet), then we want to drag in
wpa_supplicant by default. That is accomplished by suggesting wpa_supplicant
package.

Otherwise, the user installing NetworkManager-wifi might get iwd,
which is only functioning if the user explicitly enables the backend
in "NetworkManager.conf".

5aa50d7c87 core: fix wrongly generating "Wired connection 1" (auto-default) for ethernet with MAC
If a profile has only "ethernet.mac-address" set, but
"connection.interface-name" not, then the previous check

    iface = nm_setting_connection_get_interface_name (s_con);
    if (!nm_streq0 (iface, nm_device_get_iface (device)))
         continue;

would wrongly consider the profile not matching for the device.
As a result, we would wrongly create a auto-default connection.

Fix that. We already call nm_device_check_connection_compatible()
above. That is fully suitable to compare the interface name and
the MAC address. We don't need to duplicate this check (wrongly).

See also commit 77d01c9094 ('settings: ignore incompatible connections
when looking for existing ones') for how this code changed.

4154d9618c bluetooth: refactor BlueZ handling and let NMBluezManager cache ObjectManager data
This is a complete refactoring of the bluetooth code.

Now that BlueZ 4 support was dropped, the separation of NMBluezManager
and NMBluez5Manager makes no sense. They should be merged.

At that point, notice that BlueZ 5's D-Bus API is fully centered around
D-Bus's ObjectManager interface. Using that interface, we basically only
call GetManagedObjects() once and register to InterfacesAdded,
InterfacesRemoved and PropertiesChanged signals. There is no need to
fetch individual properties ever.

Note how NMBluezDevice used to query the D-Bus properties itself by
creating a GDBusProxy. This is redundant, because when using the ObjectManager
interfaces, we have all information already.

Instead, let NMBluezManager basically become the client-side cache of
all of BlueZ's ObjectManager interface. NMBluezDevice was mostly concerned
about caching the D-Bus interface's state, tracking suitable profiles
(pan_connection), and moderate between bluez and NMDeviceBt.
These tasks don't get simpler by moving them to a seprate file. Let them
also be handled by NMBluezManager.

I mean, just look how it was previously: NMBluez5Manager registers to
ObjectManager interface and sees a device appearing. It creates a
NMBluezDevice object and registers to its "initialized" and
"notify:usable" signal. In the meantime, NMBluezDevice fetches the
relevant information from D-Bus (although it was already present in the
data provided by the ObjectManager) and eventually emits these usable
and initialized signals.
Then, NMBlue5Manager emits a "bdaddr-added" signal, for which NMBluezManager
creates the NMDeviceBt instance. NMBluezManager, NMBluez5Manager and
NMBluezDevice are strongly cooperating to the point that it is simpler
to merge them.

This is not mere refactoring. This patch aims to make everything
asynchronously and always cancellable. Also, it aims to fix races
and inconsistencies of the state.

- Registering to a NAP server now waits for the response and delays
  activation of the NMDeviceBridge accordingly.

- For NAP connections we now watch the bnep0 interface in platform, and tear
  down the device when it goes away. Bluez doesn't send us a notification
  on D-Bus in that case.

- Rework establishing a DUN connection. It no longer uses blocking
  connect() and does not block until rfcomm device appears. It's
  all async now. It also watches the rfcomm file descriptor for
  POLLERR/POLLHUP to notice disconnect.

- drop nm_device_factory_emit_component_added() and instead let
  NMDeviceBt directly register to the WWan factory's "added" signal.

d6df0339ff wwan: simplify API of nm_modem_act_stage2_config() to never fail
The previous function arguments of nm_modem_act_stage2_config() act as if the
function could fail or even postpone the action. It never did.

We cannot treat this generic. A caller needs to know whether nm_modem_act_stage2_config()
can postpone the action, and when it does, which signal is emitted upon completion. That
is, the caller needs to know how to proceed after postponing.

In other words, since this function currently cannot fail or postpone
the stage, so must all callers already rely on that. At this point it makes
no sense to pretend that the function could be any different, if all callers
assume it is not. Simplify the API.

f796be3d7d wwan: add nm_modem_manager_get_modems() to iterate over modems
Currently, we cannot ask which modems exist. NMDeviceBt may claim it
via nm_device_factory_emit_component_added(), and NMWWanFactory may
take it by listening to NM_MODEM_MANAGER_MODEM_ADDED. But that's it.

We will drop nm_device_factory_emit_component_added() because it's only
used for passing modems to NMDeviceBt. Instead, NMDeviceBt can directly
subscribe to NM_MODEM_MANAGER_MODEM_ADDED. It already has a reference
to NMModemManager.

Anyway, the NM_MODEM_MANAGER_MODEM_ADDED signal is no enough, because
sometimes when the mode appears, NMDeviceBt might not yet know whether
it should take it (because the DUN connect call is not yet complete).
Currently that never happens because dun_connect() blocks waiting for
the device. That must be fixed, by not waiting. But this opens up a
race, and NMDeviceBt might after NM_MODEM_MANAGER_MODEM_ADDED need to
search for the suitable modem: by iterating the list of all modems.

6d644c66a8 wwan: mark modems that are taken by a NMDevice as "claimed"
NMModem-s are either used by NMDeviceModem or by NMDeviceBt.
The mechanism how that is coordinated it odd:

  - the factory emits component-added, and then NMDeviceBt
    might take the device (and claim it). In that case, component-added
    would return TRUE to indicate that the modem should not be also
    used by NMDeviceModem.

  - next, if the modem has a driver that looks like bluetooth, NMDeviceModem
    ignores it too.

  - finally, NMDeviceModem claims the modem (which is now considered to
    be non-bluetooth).

I think the first problem is that the device factory tries to have this
generic mechanism of "component-added". It's literally only used to
cover this special case. Note that NMDeviceBt is aware of modems. So,
abstracting this just adds lots of code that could be solved better
by handling the case (of giving the modem to either NMDeviceBt or
NMDeviceModem) specifically.

NMWWanFactory itself registers to the NM_MODEM_MANAGER_MODEM_ADDED
signal and emits nm_device_factory_emit_component_added().
We could just have NMWWanFactory and NMDeviceBt both register to
that signal. Signals even support priorities, so we could have
NMDeviceBt be called first to claim the device.

Anyway, as the modem can only have one owner, the modem should have
a flag that indicates whether it's claimed or not. That will allow
multiple components all look at the same modem and moderate who is
going to take ownership.

eae69e33dd core: extend nm_shutdown_wait_obj_*() to support notification via a GCancellable
Now nm_shutdown_wait_obj_*() supports two styles:

 - NM_SHUTDOWN_WAIT_TYPE_OBJECT: this just registers a weak pointer
   on a source GObject. As long as the object is not destroyed
   (and the object is not unregistered), the shutdown gets blocked.

 - now new is NM_SHUTDOWN_WAIT_TYPE_CANCELLABLE: this source object
   is a GCancellable, and during shutdown, the system will cancel
   the instances to notify about the shutdown. That aside, the GCancellable
   is tracked exactly like a regular NM_SHUTDOWN_WAIT_TYPE_OBJECT (meaning:
   a weak pointer is registered and shutdown gets delayed as long as the instance
   lives).

As the rest of the shutdown, it's not yet implemented on the shutdown-side.
What is now possible is to register such cancellables, so that users can make
use of this API before we fix shutdown. We cannot fix it all at the same time,
so first users must be ready for this approach.

d19a403faa libnm/test: add unit test with consistency checks about NMSetting type info
Add test for checking the meta data for expected consistency.

This is also useful if you want to check something about the meta data
programatically.

For example, if you have the question which (if any) properties
are GObject based but also implement a to_dbus_fcn() function. Then you
can extend this code with some simple printf debugging to get a list of
those.

Or, if you want to find how many NMSettInfoProperty instances are in
static data (e.g. to determine how much memory is used). You can easily
modify this code to count them (and find 447 properties). Out of these,
326 are plain GObject based properties. Meaning, we could refactor the
code to create smaller NMSettInfoProperty instances for those, saving
thus (326 * 4 * sizeof (gpointer)) bytes (10K).

Such questions are interesting when refactoring the code.

30ce0079a8 libnm: drop unused property setter NM_DEVICE_MANAGED
NM_DEVICE_MANAGED was intended to work like NM_DEVICE_AUTOCONNECT:
namely it would call the D-Bus property setter synchronously.

But such behavior is horrendous, we certainly don't want blocking calls
during a property getter.

Luckily this one instance was unused and never worked as the property
was marked as G_PARAM_READABLE. Just drop the setter.

7db00be6b7 libnm: inline NMManager's get_permissions_sync()
Synchrnous initialization is problmatic and needs cleanup.

get_permissions_sync() is an internal function, that has only one
caller. We need to keep track of functions that make synchronous D-Bus
calls. Move the synchronous call into the caller, so that it's clearer
who calls such API.

be3712f6fb libnm: drop nm_dbus_new_connection() helper API
We don't need a wrapper around g_bus_get*(). Just use
it directly.

I guess in the past this had some use when we were using
a private socket too. Those days are gone. If we are going
to re-introduce private socket support, then we probably should
come up with a better solution.

908fadec96 shared: add NMRefString
I'd like to refactor libnm's caching. Note that cached D-Bus objects
have repeated strings all over the place. For example every object will
have a set of D-Bus interfaces (strings) and properties (strings) and an
object path (which is referenced by other objects). We can save a lot of
redundant strings by deduplicating/interning them. Also, by interning
them, we can compare them using pointer equality.

Add a NMRefString implementation for this.

Maybe an alternative name would be NMInternedString or NMDedupString, because
this string gets always interned. There is no way to create a NMRefString
that is not interned. Still, NMRefString name sounds better. It is ref-counted
after all.

Notes:

 - glib has GQuark and g_intern_string(). However, such strings cannot
   be unrefered and are leaked indefinitely. It is thus unsuited for
   anything but a fixed set of well-known strings.

 - glib 2.58 adds GRefString, but we cannot use that because we
   currently still use glib 2.40.
   There are some differences:

     - GRefString is just a typedef to char. That means, the glib API
       exposes GRefString like regular character strings.
       NMRefString intentionally does that not. This makes it slightly
       less convenient to pass it to API that expects "const char *".
       But it makes it clear to the reader, that an instance is in fact
       a NMRefString, which means it indicates that the string is
       interned and can be referenced without additional copy.

     - GRefString can be optionally interned. That means you can
       only use pointer equality for comparing values if you know
       that the GRefString was created with g_ref_string_new_intern().
       So, GRefString looks like a "const char *" pointer and even if
       you know it's a GRefString, you might not know whether it is
       interned. NMRefString is always interned, and you can always
       compare it using pointer equality.

  - In the past I already proposed a different implementation for a
    ref-string. That made different choices. For example NMRefString
    then was a typedef to "const char *", it did not support interning
    but deduplication (without a global cache), ref/unref was not
    thread safe (but then there was no global cache so that two threads
    could still use the API independently).

The point is, there are various choices to make. GRefString, the
previous NMRefString implementation and the one here, all have pros and
cons. I think for the purpose where I intend NMRefString (dedup and
efficient comparison), it is a preferable implementation.

Ah, and of course NMRefString is an immutable string, which is a nice
property.

24bbceed9b wifi: roam more aggressively
-80dBm is a very weak signal and we should roam sooner.
iwd[1] and iOS[2] default to -70dBm, Android[3] default to -73dBm.
So lets change the roaming threshold to -70dBm.
