i-network says "Unknown" or "No SIM" on N4 (mako), can't unlock the SIM

[Antti Kaijanmäki]

noticed that i-network is broken on mako. Sometimes after reboot the indicator says the modem state is either "Unknown" or "No Sim" even though the SIM is present.

for now the workarounds are:

If developer mode is not enabled:
 - reboot the phone until you can enter the PIN

if developer mode is enabled:
$ adb shell
$ restart indicator-network

# system-image-cli -i

This bug can be replicated at least as far back as 255. I can't make it happen with 250 anymore, though.

I just made it happen with mako + utopic #264. Output from list-modems shows the SIM is present and current PIN locked. Here's the properties of ofono's SimManager after boot:

 [ org.ofono.SimManager ]
        PreferredLanguages = en
        BarredDialing = 0
        Retries =
        SubscriberNumbers =
        Present = 1
        CardIdentifier = 8901260002766867909
        PinRequired = pin
        FixedDialing = 0
        LockedPins = pin

I also tried to reproduce on krillin w/the updated indicator from the urfkill silo, and could not make it happen. Seems to be isolated to mako only.

[Tony Espy (awe)]

As this only occurs on mako, maybe this should be reduced in importance to High?

[Antti Kaijanmäki (kaijanmaki)]

agreed.

[Jussi Pakkanen (jpakkane)]

This can't be reproduced on 279. Maybe some other landing fixed this too?

[Tiago Salem Herrmann (tiagosh)]

We are hitting the same problem in telepathy-ofono, only reproducible on mako too.
It would be good to check the dbus traffic to make sure the PinRequired property is available once the interface becomes available, and if PropertyChanged() is being emitted correctly after that.

This PR makes ofono signal ordering more sensible:

https://github.com/rilmodem/ofono/pull/129

Although this bug only happens for mako it is not impossible that it might have appeared for krillin too, as both plugins worked in a similar way.

For those interested, here is the event sequence that probably makes the bug appear:

1.- ofono_sim_register() is called. It calls ofono_modem_add_interface(), which calls g_idle_add() before notifying of the new interface.

2.- __ofono_sim_recheck_pin() is called. PinRequired is signalled.

3.- Now trigger_interface_update(), the argument to g_idle_add() in point 1, is called so SimManager interface is signalled.

4.- telepathy-ofono calls GetProps() but, surprise, no properties are there. This is because the SIM atom has not been notified that there is a SIM, so sim_get_properties() returns no reply.

5.- Present is finally signalled when ofono_sim_inserted_notify(TRUE) is called from the *ril/mtk plugin*. This can happen before of after the sequence described, as there is no coordination with rilmodem SIM driver. When it happens as described the bug appears.

Status changed to 'Confirmed' because the bug affects multiple users.
