The accessor functions just look whether a certain flag is set. As these
functions have a different name then the flags, this is more confusing
then helpful. For example, if you want to know where the NM_GENERATED
flag matters, you had to know to grep for nm_settings_connection_get_nm_generated()
in addition to NM_SETTINGS_CONNECTION_FLAGS_NM_GENERATED.
The accessor function hid that the property was implemented as
a connection flag. For example, it was not immediately obvious
that nm_settings_connection_get_nm_generated() is the same
as having the NM_SETTINGS_CONNECTION_FLAGS_NM_GENERATED flag
set.
Drop them.

Waiting for carrier on startup is probably the same times that carrier
needs, e.g. on an MTU change. Use the same timing.
Note, that as carrier-wait-timeout is no configurable, this
configuration applies to both -- as the manual page already
claims to do.

like in the case of a cdc-wdm device, get the mtu from the ip interface

Also downgrade a few intermediate error logging messages
for failures that happen while start_sharing(). A debug
message is enough in this case, because we propagate now
the error to the caller, which logs a warning anyway.

check_and_add_ipv6ll_addr() checks whether a link-local address is
already present in priv->ip6_config and if so, it returns with no
action.
priv->ip6_config is only updated after a merge-and-apply or (in an
idle source) when the external configuration changes and so there is
no guarantee that the addresses there are up-to-date.
priv->ext_ip6_config_captured should be checked instead, because it is
updated from platform right before starting the generation of a
link-local address. Note that also linklocal6_start() already checks
the captured external configuration rather than priv->ip6_config.

If a device is 'external' (which means that NM generated an in-memory
connection to only to track the device state) we should not change its
IP configuration.

In the next commit we will modify ipX_config_merge_and_apply to never
touch external devices. When a "reapply" call is issued on an external
device we are no longer simply tracking its state but we are actively
managing it and so its sys-iface-state must be promoted to managed.

(cherry picked from commit 9e41ed4461)
When a master connection is deactivated by user, we set the
autoconnect-blocked reason 'user-request' for the connection and we
propagate the same reason to slaves. Doing so prevents the
autoactivation of slaves when the master is manually activated again,
because the only way to override the 'user-request' blocked reason is
through manual activation of slaves.
Instead what should happen is that the manual deactivation of a master
marks slaves as blocked for failed dependencies. When the master
becomes available again, slaves can autoactivate if the profile allows
it.

The _NM_GET_PRIVATE() macro already preserved and propagated

_NM_GET_PRIVATE_PTR() didn't do that. Extend the macro,

We need to pass more alias-types. Instead of having numbered

Also, fix build failure with old compiler:

_NM_GET_PRIVATE() used typeof() to propagate constness of the @self
pointer. However, that means, it could only be used with a self pointer
of the exact type. That means, you explicitly had to cast from (GObject *)
or from (void *).
The requirement is cumbersome, and often led us to either create @self
pointer we didn't need:
NMDeviceVlan *self = NM_DEVICE_VLAN (device);
NMDeviceVlanPrivate *priv = NM_DEVICE_VLAN_GET_PRIVATE (self);
or casting:
NMDeviceVlanPrivate *priv = NM_DEVICE_VLAN_GET_PRIVATE ((NMDevice *) device);
In both cases we forcefully cast the source variable, loosing help from
the compiler to detect a bug.
For "nm-linux-platform.c", instead we commonly have a pointer of type
NMPlatform. Hence, we always forcefully cast the type via _NM_GET_PRIVATE_VOID().
Rework the macro to use _Generic(). If compiler supports _Generic(), then we
will get all compile time checks as desired. If the compiler doesn't support
_Generic(), it will still work. You don't get the compile-time checking of course,
but you'd notice that something is wrong once you build with a suitable
compiler.

(cherry picked from commit 14ad1d0cd1)
- split NM_DEVICE_AUTOCONNECT_BLOCKED_INTERN in two parts:
"wrong-pin" and "manual-disconnect". Setting/unsetting them
should be tracked differently, as their reason differs.
- no longer initialize/clear the autoconnect-blocked reasons
during realize/unrealize of the device. Instead, initialize
it once when the object gets created (nm_device_init()), and
keep the settings beyond unrealize/realize cycles. This only
matters for software devices, as regular devices get deleted
after unrealizing once. But for software devices it is essential,
because we don't want to forget the autoconnect settings of
the device instance.
- drop verbose logging about blocking autoconnect due to failed
pin. We already log changes to autoconnect-blocked flags with
TRACE level. An additional message about this particular issue
seems not necessary at INFO level.
- in NMManager's do_sleep_wake(), no longer block autoconnect
for devices during sleep. We already unmanage the device, which
is a far more effective measure to prevent activation. We should
not also block autoconnect.
(cherry picked from commit 3c2b9485a7)
The flags allow for more then two reasons. Currently the only reasons
for allowing or disallowing autoconnect are "user" and "intern".
It's a bit odd, that NMDeviceAutoconnectBlockedFlags has a negative
meaning. So
nm_device_set_autoconnect_intern (device, FALSE);
gets replaced by
nm_device_set_autoconnect_blocked_set (device, NM_DEVICE_AUTOCONNECT_BLOCKED_INTERN);
and so on.
However, it's chosen this way, because autoconnect shall be allowed,
unless any blocked-reason is set. That is, to check whether autoconnect
is allowed, we do
if (!nm_device_get_autoconnect_blocked (device, NM_DEVICE_AUTOCONNECT_BLOCKED_ALL))
The alternative check would be
if (nm_device_get_autoconnect_allowed (device, NM_DEVICE_AUTOCONNECT_ALLOWED_ALL) == NM_DEVICE_AUTOCONNECT_ALLOWED_ALL)
which seems odd too.
So, add the inverse flags to block autoconnect.
Beside refactoring and inverting the meaning of the autoconnect
settings, there is no change in behavior.
(cherry picked from commit 5279ab5be6)
nm_device_can_auto_connect() only has one caller, auto_activate_device()
in NMPolicy.
That caller already checks whether the connection has autoconnect
enabled, so drop the duplicate check.
This saves some duplication, but it also makes some sense:
NMSettingsConnection has a complex blocking of autoconnect,
so just looking at connection.autoconnect is not enough in
any case to determine whether the connection should autoconnect.
We move thus more handling of autoconnect to NMPolicy, where
it belongs.
(cherry picked from commit 6fff832fe3)
OLPC devices cannot autoconnect, according to can_auto_connect().
We should instead reject any attempt to autoconnect earlier, via
get_autoconnect_allowed().
(cherry picked from commit 7074b88a6a)
Derived classes should not modify or overwrite this essential behavior
of can_auto_connect(). It doesn't belong to the virtual function.

The number of authentication retires is useful also for passwords aside
802-1x settings. For example, src/devices/wifi/nm-device-wifi.c also has
a retry counter and uses a hard-coded value of 3.
Move the setting, so that it can be used in general. Although it is still
not implemented for other settings.
This is an API and ABI break.
Only NMPolicy should be concerned with handling autoconnect, and
blocking it.
Move the code. Note that there is a slight possible change in
behavior, as the order of when the connection is blocked changes,
based on the different times when the device changed signal gets
executed. But that shouldn't be a problem.
Since commit 4a6fd0e83e (device: honor the
connection.autoconnect-retries for 802.1X) and the related bug bgo#723084,
we reuse the autoconnect-retries setting to control the retry count
for requesting passwords.
I think that is wrong. These are two different settings, we should not
reuse the autoconnect retry counter while the device is still active.
For example, the user might wish to set autoconnect-retries to infinity
(zero). In that case, we would retry indefinitly to request a password.
That could be problematic, if there is a different issue with the
connection, that makes it appear tha the password is wrong.
A full re-activation might succeed, but we would never stop retrying
to authenticate. Instead, we should have two different settings for
retrying to authenticate and to autoconnect.
This is a change in behavior compared to 1.8.
