- don't include "nm-default.h" in header files. Every source file must
include as first header "nm-default.h", thus our headers get the
default include already implicitly.
- we don't support compiling NetworkManager itself with a C++ compiler. Remove
G_BEGIN_DECLS/G_END_DECLS from internal headers. We do however support
users of libnm to use C++, thus they stay in public headers.
(cherry picked from commit f19aff8909)
Extend the "ethernet.cloned-mac-address" and "wifi.cloned-mac-address"
settings. Instead of specifying an explicit MAC address, the additional
special values "permanent", "preserve", "random", "random-bia", "stable" and
"stable-bia" are supported.
"permanent" means to use the permanent hardware address. Previously that
was the default if no explict cloned-mac-address was set. The default is
thus still "permanent", but it can be overwritten by global
configuration.
"preserve" means not to configure the MAC address when activating the
device. That was actually the default behavior before introducing MAC
address handling with commit 1b49f941a6.
"random" and "random-bia" use a randomized MAC address for each
connection. "stable" and "stable-bia" use a generated, stable
address based on some token. The "bia" suffix says to generate a
burned-in address. The stable method by default uses as token the
connection UUID, but the token can be explicitly choosen via
"stable:<TOKEN>" and "stable-bia:<TOKEN>".
On a D-Bus level, the "cloned-mac-address" is a bytestring and thus
cannot express the new forms. It is replaced by the new
"assigned-mac-address" field. For the GObject property, libnm's API,
nmcli, keyfile, etc. the old name "cloned-mac-address" is still used.
Deprecating the old field seems more complicated then just extending
the use of the existing "cloned-mac-address" field, although the name
doesn't match well with the extended meaning.
There is some overlap with the "wifi.mac-address-randomization" setting.

Instead of accessing the singleton getter nm_settings_get(), obtain
the settings instance from the device instance itself via
nm_device_get_settings().
Introduce the nm_device_ip_method_failed() function to check if the
failure of an IP method should cause the activation to fail, and use
it where appropriate.

Get rid of NM_UNMANAGED_DEFAULT and refine the interaction between
unmanaged flags, device state and managed property.
Previously, the NM_UNMANAGED_DEFAULT was special in that a device was
still considered managed if it had solely the NM_UNMANAGED_DEFAULT flag
set and its state was managed. Thus, whether the device (state) was managed,
depended on the device state too.
Now, a device is considered managed (or unmanaged) based on the unmanaged
flags and realization state alone. At the same time, the device state
directly corresponds to the managed property of the device. Of course,
while changing the unmanaged flags, that invariant is shortly violated
until the state transistion is complete.
Introduce more unmanaged flags whereas some of them are non-authorative.
For example, the EXTERNAL_DOWN flag has only effect as long as the user
didn't explicitly manage the device (NM_UNMANAGED_USER_EXPLICIT). In other
words, certain flags can render other flags ineffective. Whether the device
is considered managed depends on the flags but also at the explicitly unset flags.
In a way, this is similar to previous where NM_UNMANAGED_DEFAULT was ignored
(if no other flags were present).
Also, previously a device that was NM_UNMANAGED_DEFAULT and in disconnected
state would transition back to unmanaged. No longer do that. Once a device is
managed, it stays managed as long as the flags indicate it should be managed.
However, the user can also modify the unmanaged flags via the D-Bus API.
Also get rid or nm_device_finish_init(). That was previously called
by NMManager after add_device(). As we now realize devices (possibly
multiple times) this should be handled during realization.

Ensure the platform link with the same interface name as the
NMDevice is actually compatible with it before using the link
for initialization of device properties. If not, remove the
NMDevice and create a new one since there are kernel resources
with a different type.
Future patches will create devices long before they are backed by
kernel resources, so we need to split NMDevice object creation from
actual setup based on the backing resources.
This patch combines the NMDeviceFactory's new_link() and
create_virtual_device_for_connection() class methods into a single
create_device() method that simply creates an unrealized NMDevice
object; this method is not expected to fail unless the device is
supposed to be ignored. This also means that the NMDevice
'platform-device' property is removed, because a platform link
object may not be available at NMDevice object creation time.
After the device is created, it is then "realized" at some later
time from a platform link (for existing/hardware devices via the
realize() method) or from an NMConnection (for newly created software
devices via the create_and_realize() NMDeviceClass methods).

Configuration commit is an unsafe thing to do for assumed connections,
it can remove an externally added address we don't know about yet.
The device already has a link-local address; for an assumed connection
it's the reason we assumed the method=link-local in the first place.
Make all mac-address properties (including NMSettingBluetooth:bdaddr,
NMSettingOlpcMesh:dhcp-anycast-addr, and NMSettingWireless:bssid) be
strings, using _nm_setting_class_transform_property() to handle
translating to/from binary form when dealing with D-Bus.
Update everything accordingly for the change, and also add a test for
transformed setting properties to test-general.
Previously, src/nm-ip4-config.h, libnm/nm-ip4-config.h, and
libnm-glib/nm-ip4-config.h all used "NM_IP4_CONFIG_H" as an include
guard, which meant that nm-test-utils.h could not tell which of them
was being included (and so, eg, if you tried to include
nm-ip4-config.h in a libnm test, it would fail to compile because
nm-test-utils.h was referring to symbols in src/nm-ip4-config.h).
Fix this by changing the include guards in the non-API-stable parts of
the tree:
- libnm-glib/nm-ip4-config.h remains NM_IP4_CONFIG_H
- libnm/nm-ip4-config.h now uses __NM_IP4_CONFIG_H__
- src/nm-ip4-config.h now uses __NETWORKMANAGER_IP4_CONFIG_H__
And likewise for all other headers.
The two non-"nm"-prefixed headers, libnm/NetworkManager.h and
src/NetworkManagerUtils.h are now __NETWORKMANAGER_H__ and
__NETWORKMANAGER_UTILS_H__ respectively, which, while not entirely
consistent with the general scheme, do still mostly make sense in
isolation.
We want to set the WWAN config last, to ensure that the configuration we
use overwrites anything that pppd might have set, becuase it touches some
stuff itself. That means we have to keep the WWAN config separate, since
dev_ip4_config is used for DHCP and IPv4LL, which we always set first to
ensure they these don't overwrite external, administrator added config
(eg, priv->ext_ip4_config).
This also synchronizes the IPv4 config path with the upcoming IPv6
config path.
The IP interface may have its own hardware address (like the net
port for WWAN devices) and that's the hardware address that must be
used for DHCP and IPv6 SLAAC, not the hardware address (if any) of
the NMDevice itself.
This patch does change the NMDevice hardware address property to
always be the Device's hardware address, instead of the IP interface
hardware address. This means that ADSL and WWAN will no longer
change their hardware address to the hardware address of their
IP interface. But in all these cases, the hardware address is
non-existent (PPP) or transient and meaningless (WWAN/ADSL).
If the initial attempt to assume a connection on a device fails, and
the device remains un-activated, but then something changes its
configuration externally, try to generate a new connection and assume
that.
Add a generic signal that devices can use to indicate that something
material in the network situation changed, and that auto-activation
may now be possible. This reduces specific knowledge of device types
in the policy.
In reality the connection provider (NMSettings) is always the same
object, and some device plugins need access to it. Instead of
cluttering up the device plugin API by passing the provider into
every plugin regardless of whether the plugin needs it, create
a getter function.
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.
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.
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.
