Old init-scripts that did not yet understand this key will have
mac-address-randomization explicitly disabled. This is to ensure
that old connections don't change behavior.
Thus, the writer must always write the value explicitly.
Downside is, if somebody creates a quick ifcfg-file, the feature
is disabled by default.
If the supplicant supports it and the connection requests it, tell
the supplicant to randomize the MAC address for the association.
In addition, like both iOS, Android, and other OSs always randomize
the MAC address when performing a WiFi scan.
NMExportedObject now derives from GDBusObjectSkeleton, which is what
GDBusObjectManagerServer wants. The main GDBusConnection and each
private server connection now gets a new GDBusObjectManagerServer,
and exported objects are registered with that instead of individually
exporting each GDBusInterfaceSkeleton.
Previously exported objects were not referenced by the BusManager,
but instead removed from the exports hash via weak references. The
GDBusObjectManagerServer instead references exported objects, which
can make them live much longer than they did before.

With ObjectManager we can not export ObjectSkeletons to multiple connections --
the manager would unexport the InterfaceSkeletons upon its destruction.
It seems easiest to just drop the private socket altogether; It was broken for
broken for some time and noone noticed anyway. Also startup before D-Bus is
still broken: NetworkManager would reconnect to the bus but multiple managers
won't notice the bus is around (we'll never see firewalld or policykit come up).
We should probably just stop pretending we support operation without a real
D-Bus server. With the advent of kdbus this makes even more sense.
In debug-mode, test_ip4_address_peer_zero() used to print the
result of `ip address show`. That fails for fake-platform
because the device does not exists.
Just don't do that.
Synopsis:
nmcli connection clone [--temporary] [id|uuid|path] <ID> <new name>
It copies the <ID> connection as <new name>. The command is very useful
if there is a connection, but another one is needed for a related
configuration. One can copy the existing profile and modify it for the
new situation.
For example:
$ nmcli con clone main-eth second-eth
$ nmcli con modify second-eth connection.interface-name em4

Commit d518278011 changed
the hashing for the APs to use direct-hashing.
That was wrong because get_ap_by_path() needs a full
string-comparison.
Fixes: d518278011
If __x is signed and its value is the minimum allowed for the type,
(__x - 1) causes a signed overflow, which has an undefined
behavior. Compiling with -fsanitize=undefined produces the warnings:
test-general.c:4499:619: runtime error: signed integer overflow: -2147483648 - 1 cannot be represented in type 'int'
test-general.c:4506:681: runtime error: signed integer overflow: -2147483648 - 1 cannot be represented in type 'TEST_IS_POWER_OF_TWP_ENUM_SIGNED'
test-general.c:4501:619: runtime error: signed integer overflow: -9223372036854775808 - 1 cannot be represented in type 'long int'

Change the order of expressions to avoid this.

When exiting after an error we must set the quitting flag in
nm-exported-object.c because during program destruction there can be
still exported objects which get disposed.
Fixes the following assertion:

Now that NM follows the supplicant's scan list and CurrentBSS, any AP that isn't
known to the supplicant will be 'fake', and priv->current_ap always tracks
CurrentBSS.
We can then simplify link_timeout_cb() because any AP that would have been
force-removed before will now be marked "fake" if it's unknown to the supplicant,
and will always be removed by set_current_ap(), so we can remove the force
argument. To better fix#733105 we never want to remove an AP known to
the supplicant, even if it we failed to connect to it.

Since commit 7cb323d923,
nm_ap_new_from_properties() will always return an
AP with BSSID set. Restore the assertion during
try_fill_ssid_for_hidden_ap().
This reverts commit e9bc18d2a7.
Differently from GLib timeout sources, systemd ones are always
one-shot and therefore we must return G_SOURCE_REMOVE in the callback,
otherwise the timer will be scheduled again.
In most cases things were working correctly because usually the
callback also unreferences the source event, but when this doesn't
happen the timer will trigger multiple times as reported in the bug
below.

gi now emits a warning when not loading a specific library
version [1]:
./generate-setting-docs.py:21: PyGIWarning: NM was imported without specifying a version first. Use gi.require_version(NM, 1.0) before import to ensure that the right version gets loaded.
from gi.repository import NM, GObject
Seems require_version() is reasonably old to just always use it without
breaking on older versions [2].

The autoconf macro for GIR passes $CFLAGS to g-ir-scanner.
g-ir-scanner extends those flags with the system-default which
includes -D_FORTIFY_SOURCE=2. Probably it should not do that,
but if you disable optimization, this results in a compler warning
in "/usr/include/features.h" [1]
export CFLAGS='-O0'
# Happens both with clang or gcc.
#export CC=clang
git clean -fdx
./autogen.sh
make
Work around that by injecting -Wno-error to $CFLAGS when invoking
g-ir-scanner.

Prevsiouly, the ifcfg-rh service and the regular NetworkManager
were both exported on the same D-Bus connection. That had the
effect, that on both services ("com.redhat.ifcfgrh1" and
"org.freedesktop.NetworkManager") all objects were visible.
This is also problematic later when we use GDBusObjectManager
for the org.freedesktop.NetworkManager service.
Export the ifcfg service on a separate bus connection.
One downside is, that we don't bother exporting the service
on the private socket and thus the service is not available
without D-Bus daemon.
Also, if the bus disconnects, we don't retry or recover. Instead
the D-Bus service is dead until restart.
