Instead of hacky stuff in the Manager, let plugins themselves indicate
which links should be ignored (because they are really child links that
are controlled by a different device that the plugin handles).
Instead of having a bunch of logic in the Manager for determining the
VLAN and Infiniband virtual interface names, move the type-specific
logic into the plugins themselves.
Instead of looping over all plugins and asking each plugin whether it
can handle a link or a connection, have them advertise the link and
connection types they support, and use that when creating new devices.
For existing devices, depending on the order that netlink sends interfaces to
us, the parent may be found after the VLAN interface and not be available when
the VLAN interface is constructed. Instead of failing construction, when a
NMDeviceVlan has no parent keep it unavailable for activation. Then have
the Manager notify existing devices when a new device is found, and let
NMDeviceVlan find the parent later and become available via that mechanism.
This doesn't apply to VLANs created by NM itself, because the kernel requires
a parent ifindex when creating a VLAN device. Thus this fix only applies to
VLANs created outside NetworkManager, or existing when NM starts up.
link_extract_type() would return the NMLinkType and a
@type_name string. If the type was unknown, this string
was rtnl_link_get_type() (IFLA_INFO_KIND).
Split up this behavior and treat those values independently.
link_extract_type() now only detects the NMLinkType. Most users
don't care about unknown types and can just use nm_link_type_to_string()
to get a string represenation.
Only nm_platform_link_get_type_name() (and NMDeviceGeneric:type_description)
cared about a more descriptive type. For that, modify link_get_type_name()
to return nm_link_type_to_string() if NMLinkType could be detected.
As fallback, return rtnl_link_get_type().
Also, rename the field NMPlatformLink:link_type to "kind". For now this
field is mostly unused. It will be used later when refactoring platform
caching.
Move the cleanup of the generated assumed connection to active connection
dispose. If the connection vanishes earlier (explicit deletion from client),
tear down the reference so that we don't try to remove it redundantly.

Most nm_platform_*() functions operate on the platform
singleton nm_platform_get(). That made sense because the
NMPlatform instance was mainly to hook fake platform for
testing.
While the implicit argument saved some typing, I think explicit is
better. Especially, because NMPlatform could become a more usable
object then just a hook for testing.
With this change, NMPlatform instances can be used individually, not
only as a singleton instance.
Before this change, the constructor of NMLinuxPlatform could not
call any nm_platform_*() functions because the singleton was not
yet initialized. We could only instantiate an incomplete instance,
register it via nm_platform_setup(), and then complete initialization
via singleton->setup().
With this change, we can create and fully initialize NMPlatform instances
before/without setting them up them as singleton.
Also, currently there is no clear distinction between functions
that operate on the NMPlatform instance, and functions that can
be used stand-alone (e.g. nm_platform_ip4_address_to_string()).
The latter can not be mocked for testing. With this change, the
distinction becomes obvious. That is also useful because it becomes
clearer which functions make use of the platform cache and which not.
Inside nm-linux-platform.c, continue the pattern that the
self instance is named @platform. That makes sense because
its type is NMPlatform, and not NMLinuxPlatform what we
would expect from a paramter named @self.
This is a major diff that causes some pain when rebasing. Try
to rebase to the parent commit of this commit as a first step.
Then rebase on top of this commit using merge-strategy "ours".
Even Fedora is no longer shipping the WiMAX SDK, so it's likely we'll
eventually accidentally break some of the code in src/devices/wimax/
(if we haven't already). Discussion on the list showed a consensus for
dropping support for WiMAX.
So, remove the SDK checks from configure.ac, remove the WiMAX device
plugin and associated manager support, and deprecate all the APIs.
For compatibility reasons, it is still possible to create and save
WiMAX connections, to toggle the software WiMAX rfkill state, and to
change the "WIMAX" log level, although none of these have any effect,
since no NMDeviceWimax will ever be created.
nmcli was only compiling in support for most WiMAX operations when NM
as a whole was built with WiMAX support, so that code has been removed
now as well. (It is still possible to use nmcli to create and edit
WiMAX connections, but those connections will never be activatable.)
The connection now might be being activated on another device. Defer the
removal until we're sure the activation request will proceed and only add the
active connection afterwards.

If a connection is already active let's keep it on the same device. This makes
it possible to reactivate a connection without client knowing which device is
it active on.

Some out of tree drivers add Ethernet devices that are supposed to be managed
by other their tooling, e.g. VirtualBox or VMWare.
Rather than hardcoding their drivers (at least VirtualBox doesn't even set a
"driver" property in sysfs) or hardcoding a logic that identifies such devices
let's just add a possibility to blacklist them in udev. This makes it possible
for whoever who ships such a driver to ship rules that prevent NetworkManager
from managing the device itself.
Furthermore it makes it possible for the user with special needs leverage the
flexibility of udev rules to override the defaults. In the end the user can
decide to let NetworkManager manage default-unmanaged interfaces such as VEth
or turn on default-unmanaged for devices on a particular bus.
An udev rule for VirtualBox would look like this:
SUBSYSTEM=="net", ENV{INTERFACE}=="vboxnet[0-9]*", ENV{NM_UNMANAGED}="1"
It was confusing to understand the difference between calling nm_device_connection_is_available()
and check_connection_available(), they behaved similar, but not really
the same. Especially nm_device_connection_is_available() would look
first into @available_connetions, and might call check_connection_available()
itself. Whereas @available_connetions was also populated by testing
check_connection_available(). This interrelation makes it hard to
understand when nm_device_connection_is_available() returned true.
Rename nm_device_connection_is_available() to nm_device_check_connection_available()
and remove all direct calls of check_connection_available() in favor of
the wrapper nm_device_check_connection_available().
Now we only call nm_device_check_connection_available() with different
parameters (@flags and @specific_object). We also have the additional
guarantee that specifying more @flags will widen the result and making
a connection "more" available, while specifying a @specific_object will
restrict it.
This also changes behavior in several cases. For example before
nm_device_connection_is_available() for user-requests would always
declare matching connections available on Wi-Fi devices (only)
regardless of the device state. Now the device state gets consistently
considered.
For default-unmanaged devices it also changes behavior in complicated
ways, because before we would put connections into @available_connetions
for every device-state, but nm_device_connection_is_available() had a
special over-ride only for unmanaged-state.
This also fixes a bug, that user can activate an unavailable Wi-Fi
device:
nmcli radio wifi off
nmcli connection up wlan0

The manager wrote the user state to the state file in /var with
the key "WiMAXEnabled", but it was read from the state file as
"WimaxEnabled". Clearly that's not going to work.
Note also the comment "Just make sure we don't expect specific data being
in the connection till then (especially in validate_activation_request())."
in impl_manager_add_and_activate_connection().

Fixes: 477033b9ef
Merge the two nm_connectivity_set_online() calls into one, after
tweaking NMConnectivity to always update its internal state before
alerting callers to the new state.
When a connection has finished activating, but we don't know yet that
we have full connectivity, then find_best_device_state() should return
CONNECTED_SITE, not CONNECTING. Fixes a bug where the manager state
would repeatedly switch between those two states.
On resume configured interfaces are unmanaged to clear their pre-resume
state and then re-managed. Eventually the interface should end up moving
to the DISCONNECTED state, which should trigger an auto-activate check in
the Policy. If connectivity checking was enabled, that auto-activate check
would fail because the Manager's state was still NM_STATE_ASLEEP.
This caused bridge slaves not to auto-activate on resume, which left bridges
without connectivity.
The manager never left NM_STATE_ASLEEP when connectivity checking was
enabled due to nm_manager_update_state() returning early when kicking
off a connectivity check. Instead, the manager's state should always
be updated to accurately reflect the current state.

Also no longer increment the reference count in the getter and
properly disconnect the signals in NMManager:dispose().
Also use the defines for the signal names instead of plain strings.
Add an NMSettingsConnection:ready property, which indicates if the
connection is ready to use. Add NMSettings:startup-complete, which is
TRUE when all connections are ready. Make NMManager:startup-complete
take NMSettings:startup-complete into account.
There's no need to call `nm_session_monitor_get()` individually for each
call to `nm_auth_is_subject_in_acl()`.

INTERNAL is actually a nop right now because the only thing that
sets it is suspend/resume, which is covered by the preceding
manager_sleeping() call. But we may use this more in the future,
so add it while we're here.
Devices that are unmanaged because their parent is unmanaged
probably shouldn't assume connections either, per 4e105c50.
We've previously been just watching for state changes into UNMANAGED state. No
state change is emitted upon removal of a device which is already unmanaged.
