The simple link-types/setting-types mechanism doesn't really cut it
because for the bluetooth NAP connection.type is "bluetooth", but
it shall be primarily handled by the bridge factory.
It's internal API that allows for a basic matching of the factory.
It is however not sophisticated enough for the full complexity.
Make it as internal API only.
Functions should behave gracefully with connections that don't verify.
Especially, as _normalize_connection_type() calls
_nm_connection_find_base_type_setting() precisely with an unknown
connection.type.
Using plain numbers make it cumbersome to grep for
setting types by priority.
The only downside is, that with the enum values it
is no longer obvious which value has higher or lower
priority.
Also, introduce NM_SETTING_PRIORITY_INVALID. This is what
_nm_setting_type_get_base_type_priority() returns. For the moment
it still has the same numerical value 0 as before. Later, that
shall be distinct from NM_SETTING_PRIORITY_CONNECTION.
Since commit 74dac5f (nm-manager: try assuming connections on managed devices),
and commit f4226e7 (manager: avoid generating in memory connections
during startup for managed devices), recheck_assume_connection() also
assumes connections on devices that are currently not in sys-iface-state
"external".
That is correct, as also for fully managed devices (which are currently
in disconnected state), we want to assume external connections. However,
when doing that, we must reset the sys-iface-state to external.

In an ideal world, we should not validate connections containing
options not valid for the current bond mode. However adding such
restriction now means that during an upgrade to the new NM version
some connections that were valid before become invalid, possibly
disrupting connectivity.
Instead, consider invalid options as a normalizable error and remove
them during normalization.
Converting the setting to a "canonical" form without invalid options
is important for the connection matching logic, where such invalid
options can cause false mismatches.
In AP mode we should not look up an access point. It is wrong to
do, and it ends up marking the connection as hidden.
It seems wrong to me that if the client explicitly set
hidden=FALSE before AddAndActivate(), that complete_connection()
would still set it to TRUE if it cannot find the access
point. That is, because complete_connection() does not know
whether hidden was omitted or set intentionally by the user.
A better name is link_speed_update(), because it re-reads and
sets the speed value.
Also, move _notfiy() after logging. It doesn't matter in this
case, but we should first log, and then do actions that have potentially
complex side-effects.
Now, that NMDeviceClass:carrier_changed_notify() is no longer called as
deferred action, we can check for DCB state there, instead or registering
to the NM_DEVICE_CARRIER notifications.
Note that:
- carrier_changed_notify() has only one implementation: NMDeviceEthernet
to call get_link_speed() when carrier comes back.
- currently, calling carrier_changed_notify() with carrier=FALSE
has no effect, because NMDeviceEthernet only acts on carrier=TRUE.
- when carrier appears, nm_device_set_carrier() will call
carrier_changed() right away. We only call carrier_changed()
with carrier=TRUE only at one place. The change merley moves
carrier_changed_notify() out of the function. Apart from
that it has no effect.
- when carrier disappears, previoulsy we would delay action for
4 seconds. Hence, we would delay carrier_changed_notify() as well
-- although it has no effect.
The last point is at least ugly. Fix it by moving
carrier_changed_notify() to nm_device_set_carrier().
Coverity complains about not checking the return value:
src/settings/nm-settings-connection.c:2329: check_return: Calling "g_key_file_load_from_file" without checking return value (as is done elsewhere 6 out of 7 times).
While at it, refactor the code and check whether the timestamp
is valid.
NetworkManager-1.8.0/src/supplicant/nm-supplicant-interface.c:232: check_return: Calling "g_async_initable_init_finish" without checking return value (as is done elsewhere 7 out of 8 times).
NetworkManager-1.8.0/src/supplicant/tests/test-supplicant-config.c:528: check_return: Calling "nm_setting_802_1x_set_ca_cert" without checking return value (as is done elsewhere 13 out of 16 times).
commit a955639 (connectivity: don't do periodic checks on interval=0)
broke scheduling connectivity checks.
That is because the timer is on only scheduled if
nm_connectivity_check_enabled(), which in turn only returns TRUE
if curl_mhandle is set. However, nm_connectivity_init() would only
initialize curl_mhandle after update_config(), missing to schedule
the periodic task.

rpmdiff complains about uses of inet_aton, inet_makeaddr, inet_netof,
inet_ntoa under the IPv6 section:
usr/sbin/NetworkManager on aarch64 i686 x86_64 ppc ppc64 ppc64le s390 s390x uses function inet_aton, which may impact IPv6 support
I think the warning is bogus, but refactor our code to avoid it.
Note that systemd code still uses them, so it don't avoid the rpmdiff
warning. But let's not diverge our systemd import from upstream for this.
- for NMSettingBond:validate_ip() also avoid g_strsplit_set() which
allocates a full strv. Instead, we can do with one g_strdup().
- for test-resolvconf-capture.c, replace the functions with macros.
Macros should be avoided usually, but for test asserts they are
more convenient as they preserved the __FILE__:__LINE__ of where
the assertion fails.
Teamd is not happy about them and would fail anyway. Worse even, if we
json_loads() such a JSON, which is precisely what happens when we inject the
"hwaddr" key, we turn bad JSON into a good one in a lossy matter. Not good.

When building with -flto, we need to use linker plugins.
In case of binutils' nm, it means to prefer gcc-nm if
available.
Like for ranlib and ar, prefer gcc-nm.
- replace AC_PATH_TOOL() by AC_CHECK_TOOLS(). That is consistent
with what we do for ar,ranlib and suggested on bgo#783311.
- instead of using the variable $BINUTILS_NM, replace it by
$NM, which is more common according to bgo#783311.
- Keep recognizing $BINUTILS_NM environment, which was introduced
by commit 8bc88bcc7c. This is purely to keep previous build
scripts working. Originally I named it "$BINUTILS_NM" because
using $NM in NetworkManager seemed confusing. But well...

If there is value in such a helper function (there is), then
it should go alongside the other nm_connection_get_setting*()
helpers. NMDevice is already large enough.
The plugins may use stuff from core, but not the other way around.
Including "bluetooth/nm-bluez-common.h" is wrong.
The UUID argument is always "nap" in the NAP case. We don't need
the flexibility that it might be anything else. Just drop it.
As far as NMDevice is concerned, it anyway wouldn't (or shouldn't
know what the uuid is. It says register, and NMBluez5Manager should
figure out the details.
We'll use this to let the devices know they can retry autoactivation
because some component became available without actually having any
data that would be useful for that device.
Adjust the comment.
For the Bluetooth NAP we need a Bridge link for the BlueZ to assign the BNEP
links for PANU client connections into.
Let's disable STP by default -- it adds extra delay for the Bridge when the
BNEP link is assigned and is likely not useful for a typical client.
When the two base settings are present, use one of higher priority.
This will pick the "bridge" setting when both "bridge" and "bluetooth" are
present for a Bluetooth NAP connection.
