NMIP4Config and NMIP6Config had methods to update an existing
NMSetting. However, the functions would really only work correctly if
the passed-in setting was empty.
Change them from "update_setting" to "create_setting", and have them
create the NMSetting themselves, and update NMDevice for that.
(If we need update_setting later, we can add it, after figuring out
exactly how it's actually supposed to work.)
Firewalld call addInterface() fails with ZONE_CONFLICT if the interface
is already part of another zone. This complicates the code in NM,
because we would have to keep better track of the zone in which the
interface currently is. Which might be quite difficult because
the zone might be changed from an external program (so we would have
to monitor the firewall configuration and work around potential races).
A better and simpler fix is to simply always use the changeZone() call.
This will do the right thing, regardless if the interface is already part
of a zone or not.

The firewalld removeInterface call fails with ZONE_CONFLICT when
removing an interface from a wrong zone. This can happen, when the
connection gets modified, while being active (which is related to
bgo#724041).
By not specifying any zone, we remove the interface from the zone
where it currently is added. This behavior was introduced in upstream
firewalld with commit cc3101ab70a3997228be7bc9f45a069c7fccfa36, March 2012,
r0_2_3-1.
This is the behavior we actually want and we don't have to keep proper track
of the current zone.

This feature requires recent support from the kernel.
Most notably these upstream kernel commits are required:
- 92c0574f11598c8036f81e27d2e8bdd6eed7d76d
- 43598813386f6205edf3c21f1fe97f731ccb4f15
- 30313a3d5794472c3548d7288e306a5492030370
The latter of them was merged to upstream kernel version 3.15-rc5.

It's only ever used as an MAC address array, so we might as well
make it one instead of a string. Saves a memory allocation and
some cycles converting back and forth.
This also fixes a bug, where NMDeviceBt:check_connection_compatible()
would not set GError on mismatch of bdaddr.

Thomas points out that the previous refactoring moved the
link_changed() virtual method invocation relative to
update_for_ip_ifname_change(), which could have weird side effects
given the things that can happen there. So move it back.
Bond, bridge, and team were notifying their "slaves" properties before
the slave actually got removed from priv->slaves, meaning that
anything that looked at the property directly from a notify::slaves
handler would see the old value. Fix that.
Keep priv->slaves in the order that slaves were attached, rather than
in reverse order.
Among other things, this makes the errors from
nm_device_master_check_slave_physical_port() more consistent.
For the factory, the only public symbols should be the factory functions.
For the WWAN library, the only public symbols should be those that
NMDeviceModem and NMDeviceBt use.
Instead of having a GObject property and a factory function to get
the plugin's device type, just use the factory function, since it
always has to be around.
The mesh and Wi-Fi companion share radio hardware and firmware resources
and you need both to exist for the mesh to function properly and to
ensure that the Wi-Fi and mesh sides cooperate correctly for scanning
and activation.
If the supplicant interface object never successfully initialized, remove
the pending action to prevent warnings about "pending action already added"
when supplicant_interface_acquire() adds the pending action again.
Just listen to manager signals all the time, but only respond to
them when necessary. Clean up companion detection to be a bit
clearer, and use nm_device_queue_state() so that we don't need
an idle handler when detecting the companion from a state change
handler.
There used to be many more members of the Supplicant struct, but now
that there are only three, collapse the struct into the NMDeviceWifiPrivate
struct, renaming them slightly at the same time to shorten the names.
Second, consolidate timeout cleanup since the two remaining timeouts
don't need their own cleanup functions.
Third, start_supplicant_connection_timeout() doesn't need its own
function since g_timeout_add() never returns 0, so we don't need to
check for it.
The only reason for the small struct was the idle handler, and the
only reason for the idle handler was to ensure that state was changed
from an idle handler. We've got nm_device_queue_state() to do that
for us now, so use it.
Make Wi-Fi support a plugin using the new device factory interface.

Older Intel "ipw" devices (ipw2100, ipw2200, and ipw2915) only gained
kernel rfkill subsystem integration with 2.6.33. Before then their
custom rfkill functionality had to be polled via sysfs. Since we now
require at least a 3.x kernel, remove this old code.

If IPv6 completes first it would emit the "up" dispatcher event with IPv6
details and move the device to ACTIVATED state. But if DHCPv4 was still
running, no dispatcher event would be emitted with the DHCPv4 information
until the first lease renew. Thus dispatcher scripts would not receive
DHCPv4 information for quite some time.
Ensure that if the other IP version completes first, that when the slower
method's DHCP completes, that it emits the appropriate dhcp4-change
or dhcp6-change event so that dispatcher scripts get the information
as soon as it's available.

When WWAN airplane mode is enabled, set modems to low power state to
ensure they are in airplane mode if either (a) the machine does not
have an rfkill switch, or (b) the modem is not tied to any rfkill
switch (eg, external USB/SDIO/etc).
If the given PIN was wrong, we really don't want to try that PIN
again automatically because it might lock the SIM. To ensure that
doesn't happen, disable autoconnect so that the user must manually
request reconnection.
(this doesn't fix auto-connect-with-a-wrong-PIN completely, as
autoconnect is reset when resuming from sleep, but it's a start)
Determining when the NMDeviceModem is available and when different
connections are available is easier if the modem's state is tracked,
instead of using the separate Enabled and Connected properties.
These properties could not accurately represent the SIM lock state
and prevented NetworkManager from making the modem available for
auto-activation when locked, even if a PIN was available.
In this new scheme, the NMDeviceModem is UNAVAILABLE when the
ModemManager modem state is FAILED, UNKNOWN, or INITIALIZING. It
transitions to the NM DISCONNECTED state when the modem has finished
initializing and has not failed.
Once the NMDeviceModem is in DISCONNECTED state it can be activated
even if the SIM is locked and a PIN is required; the PIN will be
requested when starting activation, either from the connection itself
or via a secrets request. This makes auto-activation of WWAN
connections possible.
This also allows us to consolidate code dealing with modem enable/disable
into the base NMModem class using the modem state, and to log more modem
information for debugging purposes.
Since the ModemManager enabled/disabled state is a user-changable
one, and since NM can enable the modem when starting a connection,
allow modems to be available for activation whenever they are not
in airplane mode. This makes WWAN autoconnect=true connections
actually autoconnect.
If the first connection fails during ModemManager setup for fatal
reasons (missing SIM, bad PIN, not registered), autoconnect will
be blocked for that connection until activation is manually
requested and succeeds.
rfkill handling should only pay attention to actual rfkill, since
rfkill is global but the modem management service state is per-device.
Thus calculating a global state from multiple devices is very
likely to get things wrong.
Remove all of the code that used to handle that sort of thing,
which means removing the 'enable-changed' signal from the Modem
device, since now nothing external to the modem device should
need to care whether it's enabled internally or not.
Before platform raised 3 signals for each object type. Combine
them into one and add a new parameter @change_type to distinguish
between the change type.
