When using CPIN? to detect capabilities, use several possible +CME
errors as indication that the modem is at least GSM/UMTS.
E.g. to avoid situations like this one where the modem doesn't even
get into Failed state as we cannot gather capabilities:
debug_log(): (ttyMux1): --> 'AT+GCAP<CR>'
debug_log(): (ttyMux1): <-- '<CR><LF>+CME ERROR: 100<CR><LF>'
mm_serial_parser_v1_parse(): Got failure code 100: Unknown error
debug_log(): (ttyMux1): --> 'ATI<CR>'
debug_log(): (ttyMux1): <-- '<CR><LF>Cinterion<CR><LF>EHS5-E<CR><LF>REVISION 03.001<CR><LF><CR><LF>OK<CR><LF>'
debug_log(): (ttyMux1): --> 'AT+CPIN?<CR>'
debug_log(): (ttyMux1): <-- '<CR><LF>+CME ERROR: 10<CR><LF>'
mm_serial_parser_v1_parse(): Got failure code 10: SIM not inserted
debug_log(): (ttyMux1): --> 'AT+CGMM<CR>'
debug_log(): (ttyMux1): <-- '<CR><LF>EHS5-E<CR><LF>'
debug_log(): (ttyMux1): <-- '<CR><LF>OK<CR><LF>'
iface_modem_initialize_ready(): Modem couldn't be initialized: couldn't load current capabilities: Failed to determine modem capabilities.
All the previous filter rules were applicable per-port independently.
But, we also want to apply rules on a port based on the existence of
other ports on the same device (e.g. allow TTY if the device also has
a NET port). In this case, we need to wait for all ports to appear and
then apply the additional rules.
We re-use the "min wait time" timeout in the plugin-manager for this
same purpose. This timeout is setup to wait for ports to appear before
starting the probing process (e.g. so that plugin filters like the
forbidden-drivers one work). The very same timeout can therefore be
used to check whether we start the probing or not based on additional
filter rules.
The 'default' filter policy was based on blacklisting as much as
possible and otherwise allow.
The new 'strict' filter policy will be based on whitelisting as much
as much as possible, using custom defined rules, and otherwise forbid
the ports.
The new 'paranoid' filter policy is equivalent to the 'strict' filter
after having applied the blacklist rules from the 'default' filter.
Added a new '--filter-policy=[POLICY]' option in the daemon, which
allows selecting between the supported filter policies. For now, only
two policies are defined:
* default: the default policy used by ModemManager, where it tries
to probe and detect as many modem ports as possible.
* whitelist-only: only devices explicitly tagged via udev (with the
ID_MM_DEVICE_PROCESS tag) will be probed and used.
The user can tag modems (either full devices or ports independently)
to be explicitly probed by ModemManager, using the new
"ID_MM_DEVICE_PROCESS" udev tag, e.g.:
$ sudo vim /lib/udev/rules.d/78-mm-whitelist-internal-modem.rules
ACTION!="add|change|move", GOTO="mm_whitelist_internal_modem_end"
ATTRS{idVendor}=="1199", ATTRS{idProduct}=="a001", ENV{ID_MM_DEVICE_PROCESS}="1"
LABEL="mm_whitelist_internal_modem_end"
$ sudo udevadm control --reload
$ sudo udevadm trigger
This rule runs before any other filter rule.
This tag may be used e.g. by manufacturers building systems with
built-in modems that will always be available.
Distributions targeting support for multiple modem devices shouldn't
use this udev tag.
E.g. forcing a MBIM modem to run in AT-only mode:
# MM_FILTER_RULE_NET=0 \
MM_FILTER_RULE_CDC_WDM=0 \
/usr/sbin/ModemManager --debug
This is just for quick testing for now.
This new object allows configuring the filter rules applied to the
device ports. By default, for now, it implements the same rules as the
MMKernelDevice is_candidate() method, which is obsoleted.
This patch implicitly enables in the generic device backend the
manual-only greylist (ID_MM_DEVICE_MANUAL_SCAN_ONLY tag) and the
platform TTY whitelist (ID_MM_PLATFORM_DRIVER_PROBE), which were not
being applied.
The two connection and disconnection methods are ported to GTask, and
are also updated so that the reception of the unsolicited message
reporting either connect/disconnection is able to right away complete
the pending connection/disconnection attempts, as done in other
plugins like the Icera or HSO ones.
This block is a subclassed method from MMBaseBearer, which we just
happen to also use as part of the 3GPP dial logic in the connection
attempt.
So make it a separate logical block, and call the processing of the
connection attempt if one is found.
This change makes it similar to the same logic in the Icera plugin.
The Netgear AC341U seems to delay reporting packet service status
indications or actually not even send them. This leaves us with modems
in connected state in ModemManager but actually disconnected. We can
detect this situation by actively polling ourselves the connection
status.
See e.g. this case where the indication is received 2.5 mins after the
first OutOfCall error detected when loading statistics.

This update makes it possible to request connection status polling for
QMI modems via the ID_MM_QMI_CONNECTION_STATUS_POLLING_ENABLE tag.
If not given, the connection status polling will be disabled by
default, and the QMI modem will rely on WDS indications only.
The modem object is being explicitly referenced and stored in the
Context, but then never unref-ed, completely leaking a modem reference
forever.

This patch fixes the following compiler warning issued by clang:
mm-sms-part-cdma.c:301:46: mcomparison 'guint8' (aka 'unsigned char') <= 255 is always true
[-Werror,-Wtautological-constant-compare]
This allows us to reprobe the modem and respawn the
qmi-proxy in case it dies on us. This gets us access
to the modem and unsolicited notifications again. Do
this by connecting to the device-removed signal on
QmiDevice.

Instead of assuming that NULL is a valid return, make sure we return
an error instead.
This also makes it sure that if the GTask gets cancelled, the result
we set is always a valid GObject, so that the g_object_unref passed as
GDestroyNotify can be safely called always. Not a big deal anyway, as
the GTask cannot be currently cancelled.
When load_supported_storages() doesn't run the parent implementation,
the GTask is always successful. Make it explicit, in case the logic
changes in the future.
