We do the same for the original MAC address.
A device enslaved to a bond it inherits the bond's MAC address. When
NetworkManager tries to assume a connection the generated cloned-mac property
causes a mismatch with the connection that originally brought up the device,
causing the generated connection to be used instead:
NetworkManager[14190]: <debug> [1424355817.112154] [NetworkManagerUtils.c:1641]
nm_utils_match_connection(): Connection 'eth2' differs from candidate
'bond-slave-eth2' in 802-3-ethernet.cloned-mac-address

With NM_MORE_LOGGING disabled, we still want the compiler to evaluate
the argument list. By wrapping it in "if(FALSE)", we get compile time
checks, but the logging statement will be optimized out.
Saw some g_warning() about g_object_weak_unref() trying to unref a non
registed reference. While this does not fix it, let's assert that
situation a step earlier to ease debugging.
Also, move g_object_weak_ref() closer to adding the object into the
@exported hash.
[thaller@redhat.com: rewrote commit message, change to register_object()]
nm_ethernet_address_is_valid() did not check whether @addr was a valid
address in the first place. It only checked whether the address was not
equal to a few notorious MAC addresses.
At the same time, be more forgiving and accept %NULL as argument.
This fixes an assertion nm_ap_match_in_hash().
This is a well known issue that we cannot convert some libnl
objects to NMPlatformObject. The to-string function for libnl
objects is only used for debug logging. No need to assert.
Move detection of @support_user_ipv6ll to a separate function
_support_user_ipv6ll_detect() and call it immediately after the
places where we receive libnl objects from kernel, i.e.
get_kernel_object(), event_notification(), and cache_repopulate_all().
Also, whether we have support depends on the kernel and is per-system,
not per-platform-instance. Make @_support_user_ipv6ll a global variable.
This way, we don't need to pass around a NMLinuxPlatform instance.
Instead of having a nm_platform_free() function, use NM_DEFINE_SINGLETON_WEAK_REF()
and register a weak reference. That way, users who want to free the platform
instance can just unref it.
We already have nm_*_platform_setup() that gets specified
via -DSETUP. This SETUP() hook gives us all the flexiblity
we need to customize our singleton, so just do any required
setup there.
Also, it would be easier to add an alternative (hypotetical)
nm_fake_platform_setup_custom() to customize the singleton then to
parametrize the NMPlatform:setup() implementation. So this virtual
function is less flexible and redundant.
We have two hooks to modify setup of the platform singleton:
nm_linux_platform_setup() and the virtual setup() function.
On the other hand, nm_platform_setup() limits us by accepting
only a GType, instead of a prepeared platform instance.
Make the nm_platform_setup() method more flexible, so that we can
later drop the setup() hook.
setup() can be used to initialize a NMPlatform instance that is
registered as singleton via nm_platform_setup(). It should not
be used to initialize the object.
Prior to c6529a9d74, this change was
not possible because constructed() will call back into nm_platform_*()
functions, without having the singleton instance setup.
The actual logging implementation is not supposed to be called
directly, because there are macros that capture the call site
information __FILE__, __LINE__, and G_STRFUNC.
Rename the function to make clear that this is the actual
implementation.
Otherwise it stays zero and hits an assertion when the route is applied:
NetworkManager:ERROR:nm-route-manager.c:179:nm_route_manager_ip4_route_sync:
assertion failed: (known_route->ifindex)

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".
The property indicates that a device type is supported by NetworkManager, but
the plugin for handling the device is missing.
The property is accessible through D-Bus API, libnm and nmcli.

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.)
