As with the other connection-matching methods, move the loop and the
device-independent bits into NMDevice. By reusing
nm_device_check_connection_compatible(), this means that most device
types now no longer need any type-specific code for this.

nm_device_connection_match_config() sounded more generic than it
really was; rename it to nm_device_find_assumable_connection(), which
is what it really does.
There was also a lot of redundancy/cut+paste in the subclass
implementations of connection_match_config(); Improve things by moving
the looping-over-connections code into NMDevice itself, and also doing
the general-device-compatibility and IP-config checking there, leaving
the device subclasses to just verify L2 properties. Which most of them
aren't doing...

Since NMDevice has a generic get_hw_address() method now, it can do
nm_device_spec_match_list() itself (for everything except ethernet,
which needs to match against s390 subchannels too).
https://bugzilla.gnome.org/show_bug.cgi?id=693684
nm_device_connection_match_config() on an ethernet connection could
succeed for a device that was in the connection's
mac-address-blacklist, but then NM would immediately fail to activate
the connection because nm_device_connection_compatible() would check
the blacklist and return FALSE. Fix the former to match the latter.

GObject creation cannot normally fail, except for types that implement
GInitable and take a GError in their _new() method. Some NM types
override constructor() and return NULL in some cases, but these
generally only happen in the case of programmer error (eg, failing to
set a mandatory property), and so crashing is reasonable (and most
likely inevitable anyway).
So, remove all NULL checks after calls to g_object_new() and its
myriad wrappers.

The code flow is actually somewhat simpler this way since the
subclasses don't have to ask NMDeviceWired for the address
every time. Plus then NMDeviceWired doesn't have to know
anything about its subclasses in the constructor.
Rather than having NMDevice subclasses connect to their own
::state-changed signal, fix up the signal definition so they can just
override the class handler.
The idea was copied from gtk, but it's only used there in cases where
the method's wrapper function and default implementation would
otherwise have the same name, which never happens in NM because our
method implementations aren't prefixed with the type name, so it's
just noise here.
Recent versions of wpa_supplicant have a "DisconnectReason" property
that, upon a deauthentication event, contains an IEEE 802.11
"Reason Code" for why the disconnect may have occurred. We may
want to use this in the future, so add the infrastructure to pass it
around to supplicant listeners.
Helps when you need to grep the code to change a signal's signature.
Otherwise you're stuck grepping for "state" which a lot of objects
have as a signal name.
This function used to be used only from activation paths, so it
was fine to assert there because we always expected that there
would be an activation request. These days we'd like to use it
in more places, so just return NULL if there's no connection.
Many different interface types can support VLANs, including
Infiniband, WiFi, etc. So we have to create a new device class
for them instead of keeping the support in NMDeviceEthernet.
We'll want to eventually match (for VLAN) a given hardware address
that's not the device's hardware address. Only the device itself
knows which NMSetting should contain it's hardware address (ie
the 'wired' setting for NMDeviceEthernet, 'infiniband' for
NMDeviceInfiniband, etc) and VLANs take their hardware address
from the parent interface. So eventually we'll have VLAN
interfaces use these new arguments to ask their parent interface
to match the VLAN hardware address in a connection, since the
VLAN doesn't know (or need to know) what kind of interface it
really is underneath.
The check for virtual interface name was too loose, so
restrict it to VLAN only which is what actually uses it,
and ensure we have an interface name to compare against
the device.

Rather than generating enum classes by hand (and complaining in each
file that "this should really be standard"), use glib-mkenums.
Unfortunately, we need a very new version of glib-mkenums in order to
deal with NM's naming conventions and to fix a few other bugs, so just
import that into the source tree temporarily.
Also, to simplify the use of glib-mkenums, import Makefile.glib from
https://bugzilla.gnome.org/654395.
To avoid having to run glib-mkenums for every subdirectory of src/,
add a new "generated" directory, and put the generated enums files
there.
Finally, use Makefile.glib for marshallers too, and generate separate
ones for libnm-glib and NetworkManager.
Speed is gotten via ethtool on 'carrier on' event. If there is a more suitable
netlink event we should use it instead. Nonetheless, it appears to be working
fine with carrier change, because interface speed change does emit carrier offi
and on events.
There are now three places we need delayed state transitions:
1) unavailable to disconnected
2) failed to disconnected
3) bond unavailable to disconnected
(3) wasn't doing a delayed transition, but we can't change
state from inside a state-change handler otherwise we may not
end up fully processing the current state chagne. So it needs a
delayed transition too; add some generic code to make that
easier to do.
The carrier of a bonding device is the sum of the carrier state of
all its slaves. The carrier is always off if no slaves have been
attached to the master yet.
Therefore the carrier state is of no interest when making a bonding
connection available but we still want to use carrier detection to
move the connection out of ACTIVATED if the carrier of all slaves
are off.
A neat solution is to always put the bonding master directly into
DISCONNECTED whenever its state is changed to UNAVAILABLE.
This will make a bonding master available for activation immediately
and move it to DISCONNECTED whenever all slaves have been without
a carrier for 4 seconds.
In the future, the move from UNAVAILABLE to DISCONNECTED may be made
dependant on the availability of at least one configured slave.

Moves all code to match an ethernet connection into a single function
match_ethernet_connection() and use it from everywhere within
NMDeviceEthernet.
Use of match_ethernet_connection() in connection_match_config() enables
bondig connections to be successfully matched with configurations with
matching interface names.

When matching an ethernet device with connection settings, check if
the connection needs to be bound to a specific virtual kernel interface.
Signed-off-by: Thomas Graf <tgraf@redhat.com>
Some connection types such as bonding, bridging and VLAN require
specific virtual kernel interfaces identified by name to be auto
connected to the connection.
The function nm_connection_get_virtual_iface_name() returns the name
of the kernel interface if the connection type requires this
functionatlity.
Each connection base type settings class can implement the function
get_virtual_iface_name() if the connection needs to be auto connected
to a specific kernel interface.

Shortcut to access the connection linked to the activation
request of a device.
The patch only replaces usage with nm_device_get_connection()
if the existing code assumes that an activation request must
be available.

nm_utils_hwaddr_ntoa() and nm_utils_hwaddr_aton() are like
ether_ntoa()/ether_aton(), but handle IPoIB too.
nm_utils_hwaddr_atoba() is like _aton() but returns a GByteArray,
since that's what's wanted in many places.
Also remove nm_ether_ntop() and replace uses of it with
nm_utils_hwaddr_ntoa().
A bonding device is like a virtual ethernet device. We therefore reuse
nm-device-ethernet and add some special handling to detect bonding
connections.

Initial IP configuration can happen during ACTIVATED state if both
v4 and v6 are enabled, but one takes longer than the other. Thus
various checks throughout the code for IP_CONFIG were incorrect
since they depended on IP configuration only happening during the
IP_CONFIG state. Fix that by using a separate state for IP config
and using that state for various checks instead of the overall
device state.
It was somewhat pointless since the IP config is always known when
stage4 gets scheduled, so why not just pass the config to stage5
immediately? Also helps consolidate the v4/v6 failure handling
logic and makes the operational flow clearer where both v4 and
v6 are active and proceeding in parallel.
"mac-address-blacklist" property is added to the ethernet and WiFi connections.
It is the MAC addresses list of devices on which the connection won't be
activated.
