Note that this patch doesn't effectively change any code.
Functions moved from nm-system:
* nm_system_apply_ip?_config → nm_ip?_config_commit
* ip?_dest_in_same_subnet → nm_ip?_config_destination_is_direct
Functions moved from NetworkManagerUtils:
* nm_utils_merge_ip?_config → nm_ip?_config_merge_setting
Functions renamed (and moved down to form one group):
* nm_ip?_config_new_for_interface → nm_ip?_config_capture
(The rationale for the rename is that from the achitectural point of
view it doesn't matter whether the function creates a new object or
updates an existing one. After the rename, it's obvious that
nm_ip?_config_capture() and nm_ip?_config_commit() are counterparts of
each other.)
0652d9c596 changed IP states like this:
| old behaviour | new behaviour
---------------------------------------------------------
success | IP_DONE && config is not NULL | IP_DONE
failure | IP_DONE && config is NULL | IP_FAIL
But some failure paths was not updated.
nm_platform_*_sync() functions check the cached kernel configuration
items (addresses, routes) before adding addresses to the kernel.
Therefore we don't need to be so careful about pushing NetworkManager
configuration to the kernel.
This patch helps to avoid having to compare nm_ip[46]_config objects,
which should only be created when a configuration change is being
performed.
in nm_device_start_ip_check(), because it is called from the state handler
(nm_device_state_changed()).
Errors:
(devices/nm-device.c:5585):nm_device_state_changed: runtime check failed: (priv->in_state_changed == FALSE)
<info> (eth0): device state change: ip-check -> secondaries (reason 'none') [80 90 0]
The 'assume' parameter was misused for stuff that has nothing to do with
connection assumption. The 'commit' argument with reversed logic is much
clearer.
We can't clear the ip_iface until after all the routes and addresses
are updated and flushed, because the addresses and routes are
identified by the ip_iface, and if we clear the ip_iface, we don't
know which things to flush anymore.
Example: 'hso' modems have an 'iface' of 'ttyHS4' (a serial port) and
an ip_iface of 'hso0' (an ethernet port). If we clear the ip_iface too
soon, then ip_iface/ip_ifindex is invalid and thus NM has no idea what
to remove, and the default route pointing to 'hso0' sticks around.
This could also happen with other devices where the ip_iface is
different than the iface, like modems, ADSL/ATM devices, etc.
Using the new gateway-ping-timeout property, send pings to the first
gateway address until it replies or the timeout is reached, to deal
with dumb hardware that indicates carrier on but doesn't actually
pass traffic.

Just ignore this, since it happens in the current code and is
harmless. While we're here, improve the warning in the case where it
does occur to say whiich state we're overwriting. This should help
debug any future cases.
Due to the hardware address changes in 77dda53b (danw/hwlen) creating
a new Bluetooth device was crashing. The changes there assumed that the
NMDeviceBt's hardware address should only be valid when we were connected
to the device, but that's not quite true. Since we already know the remote
device's Bluetooth hardware address, we already know the hardware address
for the NMDeviceBt as well.
The function only checked whether wimax was enabled (rfkill/user pref)
and whether wimaxd was running. Only nm-device.c calls this function
for WiMAX devices, and the only two uses of it were during activation
(which is already covered by nm-device-wimax.c's is_available() function)
and when the device enters the UNAVAILABLE state, where it is used
to check for missing firmware, which is implemented by the parent
class, not WiMAX.
These turn out to be pretty useless, since their functions are already
covered by each device's state-changed handler or can be done in other
places like deactivate().

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.
nm_device_bt_new() was trying to set NM_DEVICE_MANAGED, but that's
been read-only now for a while. Fortunately, it was already trying to
set it to FALSE, which is the default, so we can just remove that
line.

NM is supposed to ignore carrier and slave states for manual/static
connections when bringing up bonds and bridges, on the theory that
since static configuration does not require connectivity, there's
no need to wait for that connectivity to happen. This wasn't
happening during the IP configuration phase, but was happening
before getting to the IP config phase where the device waits
for slaves before starting IP configuration if the method
requires connectivity.
'NM_DEVICE_IP_IFACE' has never been a writable property, just skip it and
explicitly call 'nm_device_set_ip_iface()' when the modem is managed by the old
ModemManager.

Rather than passing UDI, ifname, and driver name to the device
constructors as separate arguments, just pass the NMPlatformLink
instead and let it parse them out.
Virtual types still take UDI and ifname separately, since we create
fake NMDevices for them for autoactivating connections. That's weird
in other ways too though, so perhaps this should be revisted.
Merge the net-subsystem-monitoring functionality of NMUdevManager into
NMLinuxPlatform (and kill NMUdevManager). NMLinuxPlatform now only
emits link-added signals after udev processes the device, and uses
udev attributes to further identify the device. NMManager now
identifies devices solely based on the NMLinkType provided by the
platform.
This requires a very recent kernel to even compile, and the kernel
code is still rapidly changing (eg, adding IPv6 support). So take it
out for now, until it stabilizes.
This reverts commit 7f0f04d106.
Add hidden command line option --run-from-build-dir; with that, helpers
like nm-avahi-autoipd.action and nm-dhcp-helper will be called from the
build tree instead of libexecdir, which allows testing without having to
install first.
Helper paths are now stored in global variables instead of macros, and
get modified with that new option.

nm_device_state_changed() had a check to make sure it wasn't entered
recursively (which had been a source of bugs in the past), but it was
global rather than per-device, so it caused errors when VLANs changed
state in response to their parent device changing state. Fix that.

Some devices aren't expected to support carrier detection, so there's
no reason to have NMDevice log about it. Move that message into
NMDeviceEthernet, where failure to support carrier-detect really is
worth mentioning.
Also, make NMDeviceEthernet use NMPlatform for carrier-detection
detection (and move the MII carrier-detect-support check from
NMDeviceEthernet into NMLinuxPlatform).
Finally, have NMDeviceGeneric actually check whether the device
supports carrier detect, rather than just always assuming it doesn't.
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.
nm_device_release_one_slave() may change the list head, but the
for loop in nm_device_master_release_slaves() can't handle that.
Use a while loop instead.
