The merge of lr/udev-unmanaged-fd731014 made all devices wait until
udev found them, but that makes these three device types fail activate
when created by NM itself.
Since their availability depended on IFF_UP, they could not be
activated (eg, 'nmcli con up team0') until they were IFF_UP. But
when they are created by NM, although NM knows the ifindex the
platform ignores the interface until udev finds it. Thus immediately
after creating the interface in _internal_activate_device() it
won't be known to the platform, so the nm_device_is_available()
check that controls whether the device moves to DISCONNECTED
will fail. This prevents any activation and emits the message:
"Connection 'foo' is not available on the device %s at this time."
because the device is still in the UNAVAILABLE state.
danw asked why we care about IFF_UP for these devices, and I can't
remember why, and I don't think it makes sense to require now.

Add nm-core-types.h, typedefing all of the GObject types in
libnm-core; this is needed so that nm-setting.h can reference
NMConnection in addition to nm-connection.h referencing NMSetting.
Removing the cross-includes from the various headers causes lots of
fallout elsewhere. (In particular, nm-utils.h used to include
nm-connection.h, which included every setting header, so any file that
included nm-utils.h automatically got most of the rest of libnm-core
without needing to pay attention to specifics.) Fix this up by
including nm-core-internal.h from those files that are now missing
includes.
Most NMDevice types defined their own error domain but then never used
it. A few did use their errors, but some of those errors are redundant
with NMDeviceError, and others can be added to it.
Setting 'lacp_rate' is only possible in '802.3ad' (4) mode.
Otherwise writing to sysctl fails and results in the following
error log:
<error> [1412337854.026285] [platform/nm-linux-platform.c:2093] sysctl_set(): sysctl: failed to set '/sys/class/net/nm-bond/bonding/lacp_rate' to '0': (13) Permission denied
<warn> (nm-bond): failed to set bonding attribute 'lacp_rate' to '0'

NMDeviceBond, NMDeviceBridge, and NMDeviceTeam all used basically the
same code to generate a default interface name. Move it into
nm_utils_complete_generic().
The virtual :interface-name properties (eg,
NMDeviceBond:interface-name) are deprecated in favor of
NMSettingConnection:interface-name, and nm_connection_verify() ensures
that their values are kept in sync. So (a) there is no need to set
those properties when we can just set
NMSettingConnection:interface-name instead, and (b) we can replace any
calls to the setting-specific get_interface_name() methods with
nm_connection_get_interface_name() or
nm_setting_connection_get_interface_name().
Since we enforce the fact that bond, bridge, team, and vlan
interface-name properties match NMSettingConnection:interface-name,
nm_connection_get_virtual_iface_name() can be replaced with
nm_connection_get_interface_name() basically everywhere.
The one place this doesn't work is with InfiniBand partitions (where
get_virtual_iface_name() was actually computing the name), but for the
most part we only need to care about the interface names of InfiniBand
partitions in places where we also already need to do some other
InfiniBand-specific handling as well, so we can use an
InfiniBand-specific method
(nm_setting_infiniband_get_virtual_interface_name()) to get it.
(Also, while updating nm_device_get_virtual_device_description(), fix
it to handle InfiniBand partitions too.)
For NMDeviceWifi and NMDeviceWimax, the printf format string for
nm_utils_complete_generic() was created based on ssid/nsp. Since
these input strings are untrusted, this is a serious bug.

Include <linux/if_ether.h> and <linux/if_infiniband.h> from
nm-utils.h, to get ETH_ALEN and INFINIBAND_ALEN, and remove those
includes (as well as <net/ethernet.h> and <netinet/ether.h>, and
various headers that had been included to get the ARPHRD_* constants)
from other files where they're not needed now.
Remove all remaining GParamSpec name and blurb strings (and fix
indentation while we're there), and add G_PARAM_STATIC_STRINGS to all
paramspecs that were lacking it.
If a link's "master" property changes unexpectedly (ie, from outside
NM), update the master and slave NMDevices to reflect it, without
making any changes to them.
Assumed slave connections need to be added to their master devices,
which didn't used to happen because the devices activating assumed
connections jumped directly to stage3, bypassing all the master/slave
handling stuff.
Instead, make all assumed connections go through all activation stages,
but make sure that things which touch the device don't get done for
assumed connections. This requires moving the master/slave code out
of the override-able class methods because we need to call the
master/slave code for assumed connections, but we don't want to call
the override-able class activation methods.
Master devices depend on their slaves/ports for carrier status, so the
carrier can't factor into whether a connection is available on that
device or not. If it did, then no connections could be activated
because the device doesn't have a carrier until slaves are attached.
Use the new kernel physical_port_id interface property to recognize
when two devices are just virtual devices sharing the same physical
port, and refuse to bond/team multiple slaves on the same port.
Support new bonding options and set them carefully. The options cannot
be set arbitrarily because they interfere with each other.

Rather than having NMManager know how to parse various settings to
create each kind of software device, add a _new_for_connection()
constructor to each of them and let them call NMPlatform to create the
device correctly themselves.
Software devices don't have a UDI until udev finds them, and since we need
to know about the software devices before udev finds them the UDI will be
missing. Instead of requiring a UDI on NMDevice creation, update the
property from the NMPlatform link change signal when udev does find the
device.
Now that a UDI is no longer required for device creation, software devices
added by NM would be created in the platform_link_added_cb() signal
handler triggered by the various software device creation methods in
system_create_virtual_device() (eg nm_platform_bridge_add() etc). Then
the NMDevice created in system_create_virtual_device() would be a duplicate
and cause problems when it was added. Since system_create_virtual_device()
needs to do setup on some devices, suppress the device creation from the
platform link added handler in this function.
Much of this is a hack which should be cleaned up later.
For device types that don't override it, make
nm_device_get_hw_addr_len() use NMPlatform to find out the actual
hardware address length, rather than just defaulting to ETH_ALEN.
Fixes warnings in the logs when using tun or gre devices.
This is really, really old 2007-era code. Any NMDevice that gets
created is already supported, so there's no reason to have every
device set NM_DEVICE_CAP_NM_SUPPORTED. For those subclasses that
only set that capability, we can remove the subclass method
entirely. Next, it turns out that the "type capabilities" code
wasn't used anywhere, so remove that too. Lastly, "cipsec"
interfaces haven't been used on linux in about 5 years (they
were created by the Cisco binary-only IPSec kernel module for
Cisco VPNs long before vpnc and openswan came around) so we can
remove that code too.
With carrier handling moved to NMDevice, the only thing left in
NMDeviceWired was speed, which was actually ethernet-specific anyway.
So move that to NMDeviceEthernet, and then kill NMDeviceWired.
Change the way that nm-properties-changed-signal works, and parse the
dbus-binding-tool-generated info to get the exact list of properties
that it's expected to export.
This makes NM_PROPERTY_PARAM_NO_EXPORT unnecessary, and also fixes the
problem of properties like NMDevice:hw-address being exported on
classes where it shouldn't be.
