We made sure that the after resume synchronization was only started on
modems that had been enabled (and so unlocked). If we detect a locked
SIM card during the sync operation, it's either because the SIM card
was swapped, or because the modem was fully shutdown during the
suspension (and so the SIM requires SIM-PIN again).
Either way, we cannot sync the state cleanly at this point, we must
trigger a full modem reprobe in order to move back the modem state to
Locked.
Refresh signal strength and access technologies,
check for SIM swaps, and check if the SIM is locked.
The modem may have switched to a different
access technologies or have a different signal strength
when resuming. Moreover, the user may swap or remove
the SIM when suspended.
When calling an async method ona given type, the convention is to use
the same type in the corresponding ready() method, so that we can use
it without additional casts on the finish().
The synchronization after resume should only be needed on enabled
modems, as otherwise there is really no chance that the state of the
modem may have changed during suspend.
E.g. if a modem is failed because it doesn't have a SIM card, or if
the SIM-PIN is locked, or if the modem has never been enabled, there
is no point in attempting to synchronize the runtime state of the
modem.
The logic that creates the device identifier uses some fields that are
exposed in DBus (e.g. model, manufacturer...).
We should not attempt to load any of that info if the DBus skeleton
for the Modem interface is no longer available, as e.g. the device may
have gone away already.

There is no longer need to perform all the CID selection logic in the
broadband bearer connection procedure, we can rely on the new profile
management operations to do the same thing.
We can do this because we're sure that all the MMBroadbandModem
objects implement the MMModem3gppProfileManager interface.
Additionally, given that we now provide the profile ID value as part
of the MMBearerConnectResult, we no longer need a custom
mm_broadband_bearer_get_3gpp_cid() as we can use the generic
mm_base_bearer_get_profile_id() for the same purpose.
Using AT+CGDCONT for profile settings management (querying, updating,
reseting), AT+CGDEL for profile deletion, and AT+CGACT for activation
status management (check, deactivate).
This interface will provide support for the profile management
operations in different modem types.
This initial commit introduces support for the interface and provides
handlers for the methods that may be called in the interface.
In addition to the amount of bearers a user may connect without
multiplexing enabled (the default until now), we now also expose the
maximum number of bearers a user may connect after enabling
multiplexing over one single network interface (if supported).
The method responsible for creating the MMBearerList is now also
subclassable, so that implementations supporting multiplexing can
provide their own version with their own thresholds.
Instead of blindly assuming that we can take whatever string given as
valid UTF-8, we'll always attempt to convert from the current modem
charset into UTF-8. Before we were doing this for hex-encoded UCS2,
but not for example for GSM-7.
And due to the now applied GSM-7 conversion, the mf627a/mf627b +COPS
parsing unit tests are updated accordingly, because when converting
from an input string that contains byte 0x40 ('@' in UTF-8) as if it
were GSM-7, the 0x40 is taken as character '¡', encoded as 0xc2,0xa1
in UTF-8).
There's no point in adding a quoting option to this method; if the
caller needs the appended string quoted, it should quote it before
passing it to this method.
It was nowhere used anyway.
If the lock status cannot be read during a puk unblock attempt, reprobe
the modem. It is likely that the SIM was permanently blocked if the lock
status cannot be read.
Skip building the firmware version information with carrier config
information if the plugin already knows that the firmware upgrade
method doesn't implement carrier-specific upgrade paths.
Fixes a bug introduced in commit 7e386389, which caused user requested
disable operations to go to step
DISABLING_STEP_FIRST_AFTER_ENABLE_FAILED. For user requested disable,
the first step should be DISABLING_STEP_FIRST.
When the SIM switch doesn't happen as part of an async hot swap
detection, we should trigger the switch handling at base modem level,
which e.g. doesn't require explicit cleanup of the SIM hot swap
detection port context.
The 'SimSlots' property exposes an array of SIM object paths, with one
array item for each available SIM slot in the system. If a valid SIM
card is found in a given slot, the path of the SIM object will be
exposed in the array item; if no valid SIM card is found, the empty
object path ("/") will be exposed instead.
The 'PrimarySimSlot' property exposes which of the SIM slots available
in the system is the one configured as being primary. In a Multi-SIM
Single-Standby setup, the primary slot will be the one corresponding
to the single active SIM in the system. In a Multi-SIM Multi-Standby
setup, the primary slot will be the one configured to act as primary
(e.g. the one that will be used for the data connection) among all the
active SIM cards found.
Extended the ModemManager Signal interface to include 5G signal
information for RSRP, RSRQ and SINR via libqmi. Also extended mmci
to print 5G signal info.
Instead of using the FALSE return of the method to indicate either a
fatal error (if result_error was set) or the continuation request (if
result_error wasn't set), provide a enum that has explicit states for
all three possible values (failure, success or continue).
The disabling sequence is updated so that the steps to disable the
interfaces never fail. This is done so that the modem is not left
in an "inconsistent" enabled state, if e.g. the modem is enabled and
one of the disabling steps for the interfaces ends up failing. In this
case, it is preferred to say that the modem is disabled, than having
it wrongly enabled.
The enabling sequence is updated so that if any of the steps to enable
the interfaces fail, we end up running an implicit disabling operation
to disable all the interfaces. This is to attempt to cleanup whatever
we had enabled during the enabling operation, including e.g. the open
ports context.
