If it's not running or we can't spawn it (it's not supposed to be
autospawned anyway) we should just ignore the error and poke clients
that we've tried and failed to get user settings instead of warning
with an annoying message.
Many clients using libnm-glib (often command-line ones like nm-tool
or nmcli) aren't long-lived enough for NM to get their UID from
the bus daemon and validate their permissions via PolicyKit. So
when the NMClient object is created, get the permissions synchronously
(with a very low timeout to prevent unecessary blocking) to ensure
that the client is still on the bus when NM asks for it's credentials.
Avoids a ton of messages like:
NetworkManager[10274]: <warn> error requesting auth for org.freedesktop.NetworkManager.enable-disable-wwan: (6) Remote Exception invoking org.freedesktop.PolicyKit1.Authority.CheckAuthorization() on /org/freedesktop/PolicyKit1/Authority at name org.freedesktop.PolicyKit1: org.freedesktop.DBus.Error.NameHasNoOwner: Remote Exception invoking org.freedesktop.DBus.GetConnectionUnixUser() on / at name org.freedesktop.DBus: org.freedesktop.DBus.Error.NameHasNoOwner: Could not get UID of name ':1.95': no such name
If an NMObject listened to property change notifications from
other NMObjects and then in response to that queued up other
property changes of it's own, those would get added to the
property change list that was being iterated through already.
Each name in the change list is freed after being notified,
but the change list itself is actually freed when all
properties have been notified. So an object that queues up
another change notification ends up in _nm_object_queue_notify()
which iterates the change list where half of the data elements
are already freed...
This commit implements MAC cloning feature in NetworkManager. To support that,
'PermHwAddress' property is added into *.Device.Wired and *.Device.Wireless
interfaces. The permanent MAC address is obtained when creating the device, and
is used for 'locking' connections to the device. If a cloned MAC is specified
in connection to be activated, the MAC is set to the interface in stage1. While
disconecting, the permanent MAC is set back to the interface.
Track missing firmware and ensure the device can't be used when firmware
is missing. Add a property for missing firmware so that clients can do
something intelligent with this information.
Since forever we've used sleep/wake as the way to implement
Networking Enabled. When the state file was introduced to make the
networking and wifi states persistent, we ran into a bug where
a failed suspend (like if the machine ran out of power while
suspended) would result in networking being disabled on reboot
since suspend/resume used the same knob as enable/disable.
This patch adds a distinct call for enable/disable networking
which changes the state file, while sleep/wake no longer change
the state file.
Without these properties, the errors like these occured:
WARNING **: handle_property_changed: property 'vpn-state' changed but wasn't
defined by object type NMVPNConnection.
Fix up refcounting, plus it turns out that we already have the MAC address
lying around as a GObject data item, so we don't need to go grab it
from the connection itself.
