commit 397faef3c5 ("mm-common-helpers: add mm_autoptr helpers for
GRegex and GMatchInfo") introduces mm_autoptr(), which implements
g_autoptr() that isn't available before glib 2.44. This patch fixes the
code to consistently uses mm_autoptr().
g_assert_cmpmem() isn't available until glib 2.46, while the minimum
glib version required by ModemManager is 2.36. This patch replaces the
uses of g_assert_cmpmem() with memcmp() instead.
In preparation of deprecating the SubscriptionState property in the
Modem3gpp interface, this CL updates the altair-lte plugin to update the
Pco property in the Modem3gpp interface upon receiving %PCOINFO
notification.
And also use mm_base_modem_at_command() instead of the full() version,
as we're anyway mm_base_modem_peek_best_at_port().
This commit also fixes the logic where we make sure the finish()
method completes the GTask that is created in the async method
originally.
On the modem with firmware revision ALT3100_04_05_06_10_A8_TF
(LTEUSB_02_04_05_10_53), it's observed that port probing doesn't
complete successfully when send-delay=0 is used.
The Altair, Option HSO and Samsung plugins all use the send-delay=0
setting once the modem object has been created. For consistency, use
the same setting during port probing.
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>
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.
g_type_init() has been deprecated (and also marked with the attribute
'deprecated') since glib 2.36 as the type system is automatically
initialized. Since the minimum version of glib required by ModemManager
is 2.36, calling g_type_init() isn't necessarily in the ModemManager
code.
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.
Split into two different actions the actual COPS? response parsing and the
operator name normalization process.
Also, allow parsing not only the operator string, but also the format, mode
and the optional access technology value.
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.
This patch increases the response timeout for the probe AT commands for
altair modems.
We've been noticing some altair modems taking upto 6 seconds to respond to the
initial probe command after a reset which results in modem-manager
timing out and sending a second probe command. The modem sends a response
after about 6 seconds for the initial probe command which modem-manager
treats as response to second probe command and this results in the
modem-manager and modem going out of sync because the modem's second
probe response is treated as response to the next initialization AT command
sent by modem-manager and so on.

Update PCO handling code such that it conforms to the latest VZW network
behavior. This includes updating the way we mark a SIM as provisioned.
In the old network, only provisioned SIMs can attach to the network.
Now, unprovisioned SIMs can attach and connect to the network.

Due to a firmware issue, the modem may reply an invalid band value, such
as 0, for the %BANDCAP or %GETCFG="BAND" command. This patch moves
parse_bands_response() to mm-modem-helpers-altair-lte.c, modifies the
function to ignore any invalid band outside the range of E-UTRAN
operating bands, and add unit tests for the function.
The Altair LTE modem only uses its primary AT port for AT commands.
Instead of referencing any existing secondary port, this patch changes
MMBroadbandBearerAltairLte to explicitly use the primary port during the
connection and disconnection sequence.
A firmware bug in Altair ALT3100 bricks the modem when
- The modem is out of coverage (Registration state is unknown (CEREG: 4))
- A disconnect attempt is made using the AT%DPDNACT command.
This patch prevents this situation by failing the connect/disconnect attempts in
the altair plugin when registration state is unknown, without attempting to
connect/disconnect the modem.
This patch uses the extended error code after a registration failure to
determine if the SIM in the relevant modem is associated with a non-provisioned
account. It uses the standard AT+CEER command, but the implementation is
restricted to the altair plugin.

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().
This patch fixes own_enable_unsolicited_events_ready() to use
mm_base_modem_at_command_full_finish(), instead of
mm_base_modem_at_sequence_full_finish(), as the %STATCM=1 command is
issued via mm_base_modem_at_command_full().
