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.
A default implementation to monitor the ongoing connection is provided in the
generic MMBroadbandModem, based on AT+CGACT? to check whether the PDP context
of the connection (identified by the cached cid) is active or not.
This commit also disables the connection monitoring logic in those plugins that
have custom connection methods.
The mm_base_modem_grab_port() now receives a MMKernelDevice directly from the
plugin, which is then stored in the MMPort corresponding to the port.
This means that we have direct access to e.g. all properties set by udev rules
everywhere, and we don't need additional GUdevClient objects (e.g. like the one
used in the Huawei plugin to detect NDISDUP support during runtime).
For virtual ports (e.g. generated during unit tests), we have a new 'generic'
kernel device object which just provides the values from the kernel device
properties given during its creation.
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.
In short:
* The 'sierra-legacy' plugin will handle all the old AT based modems,
including the DirectIP ones. This plugin is filtered by driver ('sierra' or
'sierra_net') and forbidden-drivers ('qmi_wwan' and 'cdc_mbim'). This plugin
should also grab HP and AT&T branded models if they are handled by the
proper kernel driver.
* The 'sierra' plugin will only handle QMI or MBIM based Sierra modems, which
are really all the new ones. This plugin is filtered by VID (0x1199) and
driver (qmi_wwan and cdc_mbim).
For this separation to work, the 'sierra' and 'sierra_net' plugins need to be
complementary to each other.
Devices with Icera chipsets (USB305) don't support the Qualcomm
proprietary $QCPDPP command, and we must use the Icera command
instead. Otherwise authenticated bearer creation will fail.
MMBroadbandModemSierraIcera is not a subclass of
MMBroadbandModemSierra, so we cannot cast it to that type when
passing it to bearer creation. Luckily the bearer doesn't
care, so just downgrade the type to MMBroadbandModem.
This patch modifies mm_3gpp_parse_iccid() to auto-detect if an ICCID
response is character swapped or not by comparsing the major industry
identifier part of the ICCID response to the known value (89) for
telecommunication purposes. This addresses the issue where the same AT
command (e.g. AT^ICCID used by the huawei plugin) does not report ICCID
in a consistent format.
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 removes an unnecessary check of unsigned expression >= 0,
which also fixes the following clang warnings:
sierra/mm-broadband-modem-sierra.c:570:18: error: comparison of
unsigned expression >= 0 is always true
[-Werror,-Wtautological-compare]
mode >= 0 &&

Bug reported on https://code.google.com/p/chromium/issues/detail?id=235989
Patched by Yunlian Jiang <yunlian@chromium.org>
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.
Some additional fixes by Aleksander Morgado <aleksander@lanedo.com>.

The USB305 (Icera-based) apparently has a port that replies to everything
with ERROR, and that port is unusable. Make sure it's ignored, otherwise
MM may claim it as the primary AT port since it technically speaks AT.
When the serial port buffer gets full of non-AT garbage during port probing,
we were re-scheduling the next probing step, which is completely wrong, as we
then would be processing the same probing task twice. If we get a buffer full,
just cancel the AT probing cancellable, which would cancel not only the possible
AT probings, but also the custom init if there is any.
Also, make sure that the custom_init() of the plugins out there don't return an
error if the GCancellable is cancelled. Cancelling the GCancellable means we
should just stop the custom_init(), and actually sending an error in
custom_init() means that the port should be set as unsupported by the plugin, so
completely different things.
Should fix https://bugzilla.gnome.org/show_bug.cgi?id=696695
Plugins which may support QMI ports need to explicitly request QMI probing
in cdc-wdm devices. This should also avoid probing cdc-wdm ports when we know
that the plugin doesn't support them (e.g. with Ericsson MBM devices).
https://bugzilla.gnome.org/show_bug.cgi?id=696701
Older devices may crash if asked to connect right after sending the
PIN and unlocking the SIM; they simply stop responding to AT commands
around the first request for access technology and then reboot. A
delay seems prevents this behavior.
Since it's not uncommon to require a delay after SIM unlock, add one
for newer sierra_net devices as well, even though we're not quite
sure if they need one or not. It doesn't hurt, at least.
'result' may be NULL even if no error is set. Errors aren't set
because we want to continue the !TIME/!SYSTIME sequence regardless
of errors, so we can figure out which command the modem supports.
Trying to get a uint32 out of a NULL GVariant makes glib complain,
and it's wrong, so don't do that.
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.
Sierra CDMA devices don't always have QCDM ports, or if they do,
they aren't always usable. Try Sierra-proprietary commands for
loading the modem's MDN and fall back to QCDM if that fails.
This logic is now implemented by the parent broadband modem object.
Also, implement a custom initial power state loading, so that CDMA-only modems
get marked as 'offline', in order to launch !pcstate=1 to power them up during
the first enabling. The custom initial power state loading will run the parent's
implementation in non-CDMA-only modems.
