It is possible that SIM IMSI might change in roaming conditions for a sim.
Register for UIM refresh indication always and reprobe if ICCID or IMSI changes for QMI modem.
We no longer have separate mm_base_modem_process_sim_event() and
mm_broadband_modem_sim_hot_swap_detected() methods. The only
difference between both of them was that one of them would attempt to
cleanup the ports context associated to the SIM hot swap event logic
as soon as a swap was detected, in order to avoid queueing up multiple
such events.
The previous logic wasn't working well, though, as there could be
mixed AT+QMI or AT+MBIM devices that would also require that same
cleanup and so we didn't always know which one should have been
called.
Now we have a single mm_iface_modem_process_sim_event() method, which
will trigger the reprobe and disabling, but which will also perform
the cleanup of the SIM ports swap setup as specified by the
implementation.
So, if a plugin explicitly initializes the serial ports context for
SIM hot swap handling, it should also explicitly clean it up.
Also, the initialization of the serial ports context for SIM hot swap
handling is no longer done automatically for all modems, it will be
done only for those modems using it; i.e. the modems that explicitly
report support SIM hot swap handling using AT URCs.
fwupd expects device IDs which are unique for each device and its
variants. However, Quectel re-uses the same USB VID & PID among
different variants such as EG25, EC25, EC20, etc. Moreover, each
variant may have subvariants such as EG25GGB, EG25GGC, EG25AFF,
EG25AFX, etc.
Add the name of the modem to the device IDs to build more unique device
IDs such as USB\VID_2C7C&PID_0125&REV_0001&NAME_EC25GGB.
Implement eUICC change detection for QMI based modems using one of the
following mechanisms (in order of preference):
1. If the modem supports "get slot status" operation, we monitor
physical slot status indications from the modem for the active
slot to detect when ICCID changes.
2. Use "refresh register all" to subscribe refresh indications when
the eUICC triggers REFRESH operation following the enablement of
a new profile.
3. Use "refresh register" to subscribe refresh indications (file
path of EF_ICCID is used) in a similar way. This is used with
older modems that do not support "refresh register all".
If ICCID change is detected, the already existing SIM hot swap
mechanism in MM is triggered.
If any enabling/disabling command fails, we consider the operation
failed, regardless of the QGPS status. This is because e.g. enabling
involves more operations than just QGPS=1, and so we should treat a
failure in the command sequence as a failure in the whole operation.
The method that reports what location capabilities are supported must
report the capabilities provided by the parent interface plus the
additional capabilities supported by the shared implementation.
Also, simplify the logic a bit reducing the amount of implemented
methods.
Quectel emits "+QUSIM: 1" after eUICC reinitialization. Detect it
and perform SIM swap check if one is encountered.
The motivation here is that M2M eUICC profile switch causes eUICC
reset and this is one way to detect and handle profile switches
properly on Quectel modems. The existing SIM hot swap mechanism is
used as it appears to be suitable for handling profile switches as
well as physical swapping of SIM cards.
