Currently, we are not increasing the reference counter of the QrtrNode
when creating a PortQmi for a QRTR port, and we are clearing the object
when disposing the port.

These lists were used in the corresponding TTY_BLACKLIST and
TTY_MANUAL_SCAN_ONLY filter rules, in the LEGACY and PARANOID filter
types, which are no longer supported.
The DEFAULT_ALLOWED filter rule made sense only in the LEGACY filter
type, and therefore it is also now removed, leaving the
DEFAULT_FORBIDDEN fallback rule exclusively. In other words, there is
now no way to ask ModemManager to implicitly allow TTY ports; the only
way to do that is by explicit making the TTY ports fall in one filter
rule that would allow them.
wwan qcdm port is not a serial port, calling config_fd on it
will always fail, i.e.:

This message is too specific, and there are a lot of cases where it
wouldn't apply.
E.g. when a MBIM module is stuck in low power mode due to some other
reason (like hardware rfkill), this message would pop up to the users
and completely confuse them.
Having a switch() for the MBIM services when processing indications
forces us to update it on every new MBIM service added to libmbim,
because we build with -Wswitch-enum by default.
This warning type is extremely useful, and we should not stop using
it, so let's simplify a bit the indication handling code and skip
using a switch().
There are right now only 4 different service indications expected, so
it shouldn't be a big deal.
After fwupd upgrade with mbim-qdu method, MM sometimes generate plugin failed with the regenerated MHI driver.
This patch increases the mbim_device_open_full timeout from 30 seconds to 45 seconds to prevent such issue.

The original load_connection_status() method would return an
UNSUPPORTED error if connection monitoring wasn't required (which is
the default in most QMI modems).
The new reload_connection_status() method requires the check to always
be done unconditionally.
We take most of the original logic in the load_connection_status() for
the new reload_connection_status(), and we add the UNSUPPORTED error
logic exclusively in the new load_connection_status().
The load_() method is used for connection monitoring; while the
reload_() method is used to sync connection status after a
suspend/resume operation. The same method can be used for both things
in the case of AT+CGACT? based modems.
Just triggering a connection status reload won't change the actual
bearer object state.
We change the signature of the reload_connection_status_finish()
method so that it returns the actual reloaded bearer connection
status, and so both the load_ and reload_ methods can be implemented
with exactly the same method, something that was not possible before.
Once we get the new connection status reloaded, we apply it in the
bearer object only if it's DISCONNECTED (and it wasn't DISCONNECTED
before). This should cover the true real case we're interested in, and
nothing else (i.e. we won't overcomplicate the logic attempting to
handle disconnected->connected transitions detected in the sync()
operation).
when mm_iface_modem_refresh_signal() is called, we'll restart the
signal quality refresh logic already, there is no need to request
an enforced start.
The enforced start was also modifying ctx->enabled unconditionally,
which is really not ok. This logic would be enabled only when we're
registered, and that logic is fine, no need to change that.
We made sure that the after resume synchronization was only started on
modems that had been enabled (and so unlocked). If we detect a locked
SIM card during the sync operation, it's either because the SIM card
was swapped, or because the modem was fully shutdown during the
suspension (and so the SIM requires SIM-PIN again).
Either way, we cannot sync the state cleanly at this point, we must
trigger a full modem reprobe in order to move back the modem state to
Locked.
Refresh signal strength and access technologies,
check for SIM swaps, and check if the SIM is locked.
The modem may have switched to a different
access technologies or have a different signal strength
when resuming. Moreover, the user may swap or remove
the SIM when suspended.
When calling an async method ona given type, the convention is to use
the same type in the corresponding ready() method, so that we can use
it without additional casts on the finish().
The synchronization after resume should only be needed on enabled
modems, as otherwise there is really no chance that the state of the
modem may have changed during suspend.
E.g. if a modem is failed because it doesn't have a SIM card, or if
the SIM-PIN is locked, or if the modem has never been enabled, there
is no point in attempting to synchronize the runtime state of the
modem.
The mm_base_modem_sync() method is an asynchronous method that
receives a callback and user data, and therefore we MUST always
complete the async method calling that callback. Set that up with a
GTask as usual.
Also, the mm_base_modem_sync_finish() method should be implemented
along with mm_base_modem_sync(), not in the source file of the
caller of the async method. The finish() always depends on how the
async method was implemented, in our case using a GTask.
