When we receive an indication reporting a network-initiated
disconnection, convert the MBIM network error into a
MMMobileEquipmentError, and publish it in the new 'ConnectionError'
property.

When we receive an indication reporting a network-initiated
disconnection, convert the QMI call end reason into a
MMMobileEquipmentError, and publish it in the new 'ConnectionError'
property.

|
By default, fallback to "unknown" mobile equipment error when the
modem gets disconnected by the network and we don't have any way to
know a more detailed reason.
|
|
When a user-requested connection attempt fails, we not only return the
connection error to the user that requested it, we also publish the
specific connection error in DBus for others to check why the failure
happened.
|
|
This new property will provide detailed information about the failed
connection attempt, or about the network initiated disconnection. The
property will be cleared only if a new connection attempt is
triggered, and so it can be used to investigate why a given attempt
failed without needing to be the one who triggered the attempt (e.g.
so that failures in NetworkManager-triggered connection attempts can
be investigated looking at the DBus API).
The property is built as a (ss) tuple, but the libmm-glib interface
provides methods to read this property as a GError.

|
|
|
Since ModemManager 1.0 we were publishing symbols to identify all the
possible DBus error name prefixes, but these were never documented,
they were explicitly ignored in gtk-doc.
Let's provide proper documentation for them and make them first-class
API symbols.
|
|
Some of the newly deprecated enum values were introduced in 1.14.
|
|
On a failed QMI modem connection, we won't return the generic
"CallFailed" error, we'll try to convert the 3GPP verbose call end
reason to a MMMobileEquipmentError.
And if we cannot find a mapping, or if the reported error is not a
3GPP verbose call end reason, we'll return a Unknown
MMMobileEquipmentError with a string message providing detailed error
information.
|
|
Instead of having a switch with a lot of cases, provide a one to one
mapping for the MbimNwError and MMMobileEquipmentError codes in an
array, and make use of the mm_mobile_equipment_error_for_code() helper
to build the actual GError.
|
|
Update the list of mobile equipment error codes according to v17.1.0
of 3GPP TS 27.007 (March 2021).
A lot of the enum values that were prefixed with the 'GPRS_' keyword
have now been flagged as deprecated, and a new enum name given to the
corresponding value.
The deprecated symbol names are kept in the compat support to avoid
breaking API/ABI.

First, simplify the logic that attempts to find the correct error code
associated to an error text string. This logic is very flaky, as it
relies on knowing what the modems report as text string for the
different error codes, and obviously that is not always the same.
Instead of supporting all error codes in this logic, we now limit them
to a small subset with common error codes and hopefully common error
strings.
Second, in order to quickly get the error description string for a
given error code, we rework the array of supported errors so that
the index of the array is the error code itself. For mobile equipment
errors the logic is straightforward, as they're always in the [0,255]
range, but for the message errors we create an array where the index
of the array is equal to the code plus 300 as they're always in the
[300,500] range. By doing this, we avoid having an array with 300 NULL
items before the actual values we want to support.

Use the new "DMS Foxconn Set FCC authentication" command to request
the modem unlock during a power up operation.

Use the new generic FCC unlock step instead of implementing it within
the power up setup logic.

|
Use the new generic FCC unlock step instead of implementing it within
the operating mode setup logic.
The operation is implemented in the MMSharedQmi interface as it will
also be used by the MBIM modem object.
|
|
There are devices that come locked before they can be put online.
Until now we had a specific implementation for this in the generic QMI
modem, but we should have it in a more generic way for any kind of
modem.

With the recently added support for modems using QRTR, ModemManager
needs to have access to the corresponding address family so it can
interact with the modem.

This allows mobile data to work on the EG25 (and probably other modems).

The g_dbus_proxy_get_default_timeout() is by default -1 unless
explicitly updated, so the check doesn't make any sense really. We
didn't see any warning produced because mmcli provides an explicit
timeout of 30s, so it was never the default -1.

If the network has three digit MNC and MNC < 100, set the PCS digit status
field in the QMI request.
|
|
Set the MNC PCS digit status when attempting to register to a network
with 3 digit MNC and MNC < 100.
|
|
MNC PCS digit status is now available from mm_3gpp_parse_operator_id(),
so use it.
|
|

MMLocation3gpp provides MCC/MNC information as integers, so it can not
make distinction between operator codes such as XXX01 and XXX001.
This commit deprecates mm_location_3gpp_get_mobile_network_code() and
implements a new function mm_location_3gpp_get_operator_code() which
provides the MCC+MNC in string format.
The mm_location_3gpp_get_mobile_country_code() is still available as
returning the MCC as an integer does not have ambiguity issues.
|
|
MNC digit count information is lost on conversion to integers. Make it
possible for the caller to get this information through a separate
boolean.
|
|
The modem may be camping in a forbidden network just for emergency
services, and we'll be able to have a MCCMNC reported in that case,
but this does not mean the modem is registered.
So, don't consider that a valid registration flag during the new
network registration request.

We'll setup the properties only if QRTR support is being built,
otherwise we fully skip all property related setup.

For now WWAN subsystem support has only been validated for PCI/MHI
based devices and extra patches for USB based devices (qmi_wwan,
cdc-mbim...) may be required, so do not consider WWAN ports being

move the modem_load_model() async method from mm-broadband-modem-qmi.c
to mm-shared-qmi.c, and then make use of the method from both the QMI
and MBIM implementations.

If ModemManager is not built with QMI support, the generic MBIM modem
object will not have any location support, so we cannot assume that
iface_modem_location_parent will be valid and that it will have all
load_location_capabilities(), enable_location_gathering() and
disable_location_gathering() implemented.
