(cherry picked from commit 8396c58167)
Routing table entries for a device get flushed when the device is
deactivated, but rules table entries don't, so we have to flush them
by hand.
(cherry picked from commit 8de1bec803)
During queued_ip_config_change(), we eventually call update_ip_config()
and ip4_config_merge_and_apply(). These functions read the IP configuration
from platform and setup the private ip4_config instance.
Trigger this initialization after constructing the device to setup
the IP configuration.
Before, for unmanaged devices we would not call ip4_config_merge_and_apply()
until the first platform change event.
Note that in the worst case we do some unnecessary work due to this,
because queued_ip_config_change() must already be robust to be called
at any time.
(cherry picked from commit ddac52a61e)
Since 0c136c1e2, we also track the default route for devices
without active-connection (unmanaged). They must not be returned
as best_config() or as best_device(), because the caller don't
expect unmanaged devices here.
This also gets closer to the original behavior of get_best_device()
before merging default-route-manager in d4417e3460
where we also would ignore devices depending on the state.
This fixes an assertion when having an interface unmanaged
and activating it externally:

(cherry picked from commit aadef137b4)
Since 03a5a85d, NMDeviceTeam was trying to use priv->teamd_pid to
decide whether a teamd_dbus_vanished() call indicated "teamd hasn't
been started yet" or "teamd was previously started and has now
exited". But this resulted in a race condition, where at startup, a
device could call g_dbus_watch_name(), then launch teamd (causing
teamd_pid to get set), and then have gdbus report that teamd hasn't
been started yet before the newly-launched teamd managed to grab the
bus name. Since teamd_pid would already be set when
teamd_dbus_vanished() was called, it would decide that this meant
"teamd was previously started and has now exited", so it would call
teamd_cleanup(), killing the just-started teamd process.
Fix this by having teamd_dbus_vanished() check priv->tdc instead,
which doesn't get set until after the first teamd_dbus_appeared()
call.

We forgot to include the BRIDGE, so that bridge
devices got a default priority (route-metric) of 950
Add it between VLAN and MODEM type.
Also return a different metric for UNKNOWN
device types, but these priorities are not
actually expected.

In _nm_setting_new_from_dbus(), verify that the properties have the
right types, and return an error if not. (In particular, don't crash
if someone tries to assign a GBytes-valued property a non-'ay' value.)
(cherry picked from commit 76d9fc9167)
libnm-util's nm_setting_new_from_hash() needed to call
g_type_class_ref(setting_type) to ensure that the class had been
initialized by the time we fetched its properties. But in libnm-core's
version, we create the setting object before fetching the list of
properties, so we know the class will already have been initialized by
that point.
(cherry picked from commit d80e100179)
Testing WWAN connections through a Nokia Series 40 phone, addresses of family
AF_PHONET end up triggering an assert() in object_has_ifindex(), just because
object_type_from_nl_object() only handles AF_INET and AF_INET6 address.
In order to avoid this kind of problems, we'll try to make sure that the object
caches kept by NM only store known object types.
(fixup by dcbw to use cached passed to cache_remove_unknown())

The address might be zero-size, and therefore nl_addr_get_binary_addr()
returns a pointer to a zero-size array. We don't want to read past the
end of that array. Since zero-size addresses really mean an address
of all zeros, just make that happen.
As an additional optimization, if the prefix length is zero, the whole
address is host bits and should be cleared.

Merge the two nm_connectivity_set_online() calls into one, after
tweaking NMConnectivity to always update its internal state before
alerting callers to the new state.
(cherry picked from commit 0997c4b245)
When a connection has finished activating, but we don't know yet that
we have full connectivity, then find_best_device_state() should return
CONNECTED_SITE, not CONNECTING. Fixes a bug where the manager state
would repeatedly switch between those two states.
(cherry picked from commit 5e182d5577)
nm-connectivity was logging both "started" and "finished" for periodic
connectivity checks, but was only logging "finished" for manual ones,
which made the logs look weird. Fix it to log both periodic and manual
starts, and differentiate them.
Also add some additional logging to indicate when set_online() is
called, and when :state changes.
