Instead of having the parser return separate list of supported flow
controls for TE and TA, we simplify it by only returning those
settings that apply to both TE and TA.
This logic isn't perfect either, though, as some settings (e.g. '3' in
TE in some modems, specifying a different XON/XOFF behavior) may not
have a corresponding setting in the other end.
The most common cases we care about (i.e. standard XON/XOFF, RTS/CTS)
should be properly reported with this logic.

My E725 reported 125 once; that's a valid dBm and MM shouldn't report
an error when parsing it.
|
|
Allocate the results instead of passing them back on the stack, which removes
the "can't complete in idle" restriction. Also always open the QCDM port
since we can't assume it will be open already at this point.
|
|
Instead of mixing the QCDM Novatel Snapshot code directly into the
access technology checking code, split it out with its own async
result. At the same time, make sure to open the QCDM port when
it's needed, instead of assuming its already open. Since it won't
always be.

Some modems do not support CSIM lock/unlock, but they do support
querying SIM unlock retries through +CSIM command.
If CSIM lock returns with "unsupported command" do not propagate
the error and continue with the other CSIM queries instead, moreover the
CSIM lock feature is signed as FEATURE_UNSUPPORTED in Telit modem
private structure to prevent being sent again (e.g. calling CSIM
unlock AT command).

The MMPortProbe object is already referenced by the GTask object for
custom init. Instead of keeping another reference of MMPortProbe in the
CustomInitContext, this patch changes the code to simply obtain it from
the source object of GTask.

Looks like a C&P error from the AT#PSNT codepath; all the docs
I can find indicate that AT+SERVICE returns only an integer and
no commas:
<debug> (ttyUSB2): --> 'AT+SERVICE?<CR>'
<debug> (ttyUSB2): <-- '<CR><LF>+SERVICE: 3<CR><LF><CR><LF>OK<CR><LF>'
<debug> Couldn't refresh access technologies: 'Failed to parse +SERVICE response: '+SERVICE: 3''

Commit f9c63bfa0 "build,plugins: update build rules" accidentally
changed the Novatel LTE plugin from 'libmm-plugins-novatel-lte.so' to
'libmm-plugins-novatel_lte.so'. The name becomes inconsistent with other
plugin names.

MBIM does not support 3gpp location data right now. For that,
we make sure that the location interface is not reported as
supported by MBIM modems.
|
|
The operator code (MCCMNC) may also be given encoded in the current
charset (e.g. UCS2).
Based on a patch from Colin Helliwell <colin.helliwell@ln-systems.com>
|
|
The method doing the operator name normalization takes as input the
current configured modem charset. If this is UCS2, we will now just
assume this is a hint: the string may or may not come in hex/UCS2.
This logic makes the custom operator name loading in Huawei unneeded,
if the modem is configured in UCS2, we still properly process operator
names coming in plain ASCII.

Since commit e9d0989ed069, the MMDevice may be removed from the
tracking hash table when the support check operation fails to create a
modem object.
If this failure happens due to the port probe cancellations requested
during the udev removal event for a given device port, we would end up
using an already disposed object and triggering a segfault.
This fix just makes sure a full valid reference to the MMDevice object
is kept around until we're done using it.

When calling g_list_free_full() to free a GList in dispose(), it is
necessary to reset the GList pointer to NULL as dispose() may be called
more than once.

g_object_unref is in form of `void (*)(gpointer)`, which matches the
GDestroyNotify signature. An explicit GDestroyNotify cast on
g_object_unref is thus not needed.

Vendor specific plugins that support QMI or MBIM based devices need to
handle the creation of these modems themselves.

In functions
- mm_broadband_modem_lock_sms_storages
- modem_messaging_set_default_storage
return with error when using current_sms_mem1_storage as +CPMS value, but
current_sms_mem1_storage value is UNKNOWN.

The vendor id/string based rules should already be enough to get the
telit plugin bind telit devices.
This simplifies support for future Telit devices, as we wouldn't need
any additional change in the plugin. It also helps when working with
RS232 devices as the user wouldn't need to add the explicit tag to get
the devices bound to this plugin.

On modems with a single TTY for both control and data, we cannot use
the TTY to load connection status once we're in connected mode:
Connection through a plain serial AT port (ttyUSB2)
(ttyUSB2): --> 'ATD*99***2#<CR>'
(ttyUSB2): <-- '<CR><LF>CONNECT 100000000<CR><LF>'
(ttyUSB2): port now connected
Connected bearer '/org/freedesktop/ModemManager1/Bearer/0'
Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connecting -> connected)
Simple connect state (8/8): All done
checking if connected failed: Couldn't check current list of active PDP contexts: No AT port available to run command
checking if connected failed: Couldn't check current list of active PDP contexts: No AT port available to run command
checking if connected failed: Couldn't check current list of active PDP contexts: No AT port available to run command
...
So, disable connection monitoring right away if that situation is
detected:
Connection through a plain serial AT port (ttyUSB2)
(ttyUSB2): --> 'ATD*99***2#<CR>'
(ttyUSB2): <-- '<CR><LF>CONNECT 100000000<CR><LF>'
(ttyUSB2): port now connected
Connected bearer '/org/freedesktop/ModemManager1/Bearer/0'
Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connecting -> connected)
Simple connect state (8/8): All done
Connection monitoring is unsupported by the device
...

When the connection request is done via ATD, flag the port as
connected as soon as the successful response is received, so that we
remove our polling on the device right away.

The +CGSM capability is saying that the modem is a 3GPP modem, but
that doesn't necessarily mean it's a GSM/UMTS modem, it could be a
LTE-only device.
We did add the GSM_UMTS capability when +CGSM was found, so now we'll
check if the device only reports 4G-only mode, and remove the
capability if so.

We want a parser that returns the full list of combinations found.
