g_free and g_object_unref are in form of `void (*)(gpointer)`, which
matches the GDestroyNotify signature. An explicit GDestroyNotify cast on
g_free and g_object_unref is thus not needed.
This is the value which we actually suggest in the manpage for the mmcli
operation, so just use the same one.
Scanning for 3GPP networks may really take a long time, so a specific timeout must be given:
$ mmcli -m 0 --3gpp-scan --timeout=300
Found 4 networks:
21404 - Yoigo (umts, available)
21407 - Movistar (umts, current)
21401 - vodafone ES (umts, forbidden)
21403 - Orange (umts, forbidden)

Instead of setting up a custom timeout source to poll the connection status, use
the generic logic in the base bearer object, and just re-implement the command
used to check the status.
All ports of the same modem reported by the kernel will all be associated with
a common 'uid' (unique id), which uniquely identifies the physical device. This
logic was already in place, what we do now is avoid calling it the 'sysfs
path' of the physical device, because we may not want to use that to identify
a device.
This logic now also enables the possibility of "naming" the modems in a unique
way by setting the "ID_MM_PHYSDEV_UID" property in the "usb_device" that owns
all the ports.
E.g. a custom device has 4 modems in 4 different USB ports. The device path of
each USB device will always be the same, so the naming rules could go like this:
$ vim /usr/lib/udev/rules.d/78-mm-naming.rules
ACTION!="add|change|move", GOTO="mm_naming_rules_end"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.1", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-1"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.2", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-2"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.3", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-3"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.4", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-4"
LABEL="mm_naming_rules_end"
Each of the modems found will have a unique UID retrieved from the previous list
of rules. Then, "mmcli" has also been updated to allow using the UID instead of
the modem DBus path or index, e.g.:
$ sudo mmcli -m USB-MODEM-1
/org/freedesktop/ModemManager1/Modem/0 (device id '988d83252c0598f670c2d69d5f41e077204a92fd')

This patch makes declarations bind to definitions within the same module
to prevent the potential ambiguity if referenced directly.
AddressSanitizer think they violated one definition rule, although
those symbols are accessed by address through their modules and do
not depend on the order of the libararies loaded.
For Dell-branded Novatel, Sierra and Ericsson modems.
The Novatel plugin will no longer accept every Dell-branded modem, which was
the current situation. Instead, a new Dell plugin will take care of probing for
the correct vendor string, and based on the results create a specific Novatel,
Sierra or Ericsson modem.
In order to properly support this, the Novatel, Sierra and MBM plugins now
export their implementations into non-inst libraries that the Dell plugin will
import.
Also, for now, the Dell plugin doesn't make any difference between e.g. Sierra
or Ericsson MBIM implementations, just a generic MBIM modem is created in both
cases, as that is anyway what the Ericsson MBM and Sierra plugins do already.

The QCDM port commands are never cached, so remove the option from the command()
method. Will also simplify command caching afterwards as it will be an AT-only
thing.
The Novatel LTE modem only uses its primary AT port for AT commands.
Instead of referencing any existing secondary port, this patch changes
MMBroadbandBearerNovatelLte to explicitly use the primary port during the
connection and disconnection sequence.
Originally developed by:
Ben Chan <benchan@chromium.org>
This patch replaces mm_bearer_report_disconnection() with a more generic
mm_bearer_report_connection_status(), which allows reporting any
connection status of a bearer. This further allows getting rid of those
custom report_connection_status functions in plugic specific bearer
subclasses.
Note that while plugin-specific implementations can receive multiple
'MMBearerConnectionStatus' values, the generic implementation is only allowed
to receive DISCONNECTED. Plugins need to make sure that they process all the
other status values, and only report DISCONNECTED to the parent when required.
MBM:
The MBM bearer implementation of report_connection_status() expects either
CONNECTED or DISCONNECTED. If any of these is received and there is an ongoing
connection attempt, the corresponding operation will be completed. If there is
no connection attempt, we will just handle the DISCONNECTED state, calling the
parent method to notify that the modem got network-disconnected.
Icera:
The Icera bearer implementation of report_connection_status() expects either
CONNECTED, CONNECT FAILED or DISCONNECTED. If any of these is received and
there is an ongoing connection or disconnection attempt, the corresponding
operation will be completed. If there is no connection or disconnection
attempt, we will just handle the CONNECT FAILED and DISCONNECTED states,
calling the parent method (always with DISCONNECTED) to notify that the modem
got network-disconnected.
Option/HSO:
The Option/HSO bearer implementation of report_connection_status() expects
either CONNECTED, CONNECTION FAILED or DISCONNECTED. If any of these is
received and there is an ongoing connection or disconnection attempt, the
corresponding operation will be completed. If there is no connection or
disconnection attempt, we will just handle the CONNECTION FAILED and
DISCONNECTED states, calling the parent method (always with DISCONNECTED) to
notify that the modem got network-disconnected.
Huawei:
The Huawei bearer implementation of report_connection_status() expects either
CONNECTED or DISCONNECTED. These messages are not used to process pending
connection or disconnection attempts; so if they are received while one of
these is on-going, it will just be ignored. CONNECTED reports are also
ignored, so we will just handle the DISCONNECTED state, calling the parent
method to notify that the modem got network-disconnected.
Altair-LTE:
The Altair-LTE bearers will only report DISCONNECTED on network-disconnected
cases. There is no custom report_connection_status().
Novatel-LTE:
The Novatel-LTE bearers will only report DISCONNECTED on network-disconnected
cases. There is no custom report_connection_status().
We now have a single 'CurrentModes' property which contains both values in a
tuple with signature "(uu)".
Also, rename 'SetAllowedModes()' to 'SetCurrentModes()', and update the list of
arguments expected to have a single "(uu)" tuple.
This patch increases the number of retries, from 4 to 60, for connection
status check during a connection / disconnection request, which handles
some scenario when the connection / disconnection request takes more
than 5 seconds to complete.
This patches normalize a response for the AT$NWQMISTATUS command, by
replacing white-space characters with a space, before the response is
included in a DBus error message.
This patch fixes the following invalid comparison of unsigned expression:
novatel/mm-plugin-novatel.c:148:29: error: comparison of unsigned
expression >= 0 is always true [-Werror,-Wtautological-compare]
if (ctx->nwdmat_retries >= 0) {

Bug reported on https://code.google.com/p/chromium/issues/detail?id=242150
We filter the E362 because it's managed by the Novatel LTE plugin. If we also
filter out the USB551L, but it's not explicitly grabbed by any other plugin, it
will default to the Generic one.
The GetNetworkTime() response is defined to be an ISO8601 string, which
is in turn defined to be in local time. Make sure that's reflected in
the documentation, and append the timezone offset to UTC where we have
it.
Oddly, Icera devices return their time info in UTC with an offset to
the local timezone, so we have to jump through some hoops there to
convert the response to localtime based on the reported offset.

So do it during port probing. If we send this command early enough in the
first AT port being probed, it should flip the secondary ports to AT mode
before their port probing is finished.
https://bugzilla.gnome.org/show_bug.cgi?id=696696
Instead of deciding in advance which data port to use, we let the dialling
operation gather it. For the generic dialling logic, ATD-based, always an
'AT' port will be used as data port, even if we grabbed a 'net' port. Those
plugins that can work with 'net' ports will grab the specific 'net' port
themselves.
Instead of returning 3 variables in connect_finish(), return a single reference
counted struct. This simplifies how the result is built and passed within a
GSimpleAsyncResult to each _finish() method.
This also simplifies the dialling step in the 3GPP connection sequence, as we
can use the same new type.
We previously had the modem initialization command merged with some other port
setup commands in the 'modem_init' step of the 'Modem' interface. Instead of
doing this, we now split the logic into two separate steps:
A first 'enabling_modem_init' modem initialization step is to be run just after
the ports have been opened, but only during the first enabling operation, and
only if the modem was not hotplugged. A hotplugged modem is assumed to be
properly initialized already, so no need to ATZ-it. Also, we will now wait 500ms
by default after the modem initialization command has been sent, to let it
settle down.
The second 'modem_init' step will be run during the 'Modem' interface
initialization, and it currently only holds specific setup of the primary and
secondary serial ports. We'll be modifying this logic a bit in the next commits,
so no big deal to have that step name unchanged.
We use the Icon ID here because a value of 1 *always* means not roaming,
while the other values don't appear to be consistent. For example,
an ERI value of "0" is supposed to mean roaming according to the
standards, but the Novatel devices appear to use 0 to mean home.
Since we're not sure, don't depend on the ERI value itself, just
depend on the Icon ID, where we know for sure that 1 means "home".
