1264fc2108 supplicant: cleanup GObject property implementation in NMSupplicantInterface
nm_supplicant_interface_new() should be merely a convenient interface

f1fba3eb02 wifi: fix crash due to wrong ownership handling in nm_supplicant_manager_iface_release()
nm_supplicant_manager_iface_get() would cache and reuse the supplicant
interface. But no ref-counting was in place so that the first user returning
the interface via nm_supplicant_manager_iface_release() would destroy the
instance for others.

This is broken for a very long time. Which shows that we hardly ever
have a cache-hit and usually create a new instance. So, instead of
letting nm_supplicant_manager_create_interface() check for existing
supplicant interface, always create a new instance. This also makes
sense, because we would expect that per ifname only one instance is
requested at a time. Also add an assertion that we don't return
multiple supplicant interface instances for the same ifname.

Drop nm_supplicant_manager_iface_release() in favor of requiring users
to unref the returned instance.

Also, use a GSList instead of a GHashTable for the cache.

Also, previously callers would pass @is_wireless to nm_supplicant_manager_iface_get(),
but the cache lookup did not consider that value. That doesn't matter
now as we always create a new instance.

063f9185b9 supplicant: don't pass start_now argument to nm_supplicant_interface_new()
Also, don't only consider the @die_count whether to start the supplicant,
but check for is_available() -- which already considers @die_count and
@running.

004edecc81 wifi/supplicant: take object reference during availability_changed()
If the list is expected to be modified, it also means that possibly
instances will be unrefed. Probably, not yet visited instances will
not be unrefed so there is no real problem.

Just be extra cautious and take a reference to all instances first.

64ac910131 dns-manager: prevent DNS plugins from respawning too quickly
If dnsmasq (or another DNS plugin) exits immediately (for example due
to an already used port), the DNS manager keeps restarting it forever,
wasting system resources and filling logs.

Add a simple rate-limiting mechanism.

701d98acc5 device: fix check on device state in carrier_changed()
The function can now be called on unrealized devices before the
initial unmanaged flags are set and for those devices
nm_device_get_managed() will return TRUE. Since we only accept
states > UNMANAGED, return early when the condition is not met.

Fixes the following failed assertion:

carrier_changed: assertion 'priv->state >= NM_DEVICE_STATE_UNAVAILABLE' failed

76f90812f4 device: clear queued_state callback in dispose
dispose() calls _cleanup_generic_pre() which in turn already calls
nm_device_queued_state_clear(). So we would expect that at the end
of dispose() no queued-state is pending.

However, there there are crashes reports in queued_set_state() with the
device instance already destructed (rh#1270247). Add this check trying
to avoid the crash and closing in on the cause.

5996565ca9 manager: retry virtual connections when a device is added or changes
When a new device gets added or when an existing one changes name,
virtual connections that refer to it as parent device may become
ready, so let's try to activate them.

Previously we tried to activate virtual connections only on startup
and, after commit d8e1590c50 ("manager: retry device creation for
connection that would use a newly created device"), also when a
connection was added/changed, but this doesn't cover the case in which
a parent device appears or changes name at runtime.
