[C2] Mobile network unavailable, ofono crashes badly, continuously, dumps core

Bug Reports

#1

REPRODUCIBILITY: 50% (sometimes)
OSVERSION: 5.0.0.21
HARDWARE: Reeder S19 Max Pro S - s19mps - s19mps - 1.0.0.15 - aarch64
UI LANGUAGE: English (UK) (user: en_GB, os: en_GB.utf8)
REGRESSION: not specified

DESCRIPTION:

Ofono daemon crashes after trying to start up.

This was a fresh boot after having inserted a SIM for the first time. Sim-less boots before that have always gone fine.

The problem appears to be related to the fact that the second SIM Slot is ā€œdisabledā€.

PRECONDITIONS:

Possibly having Sim Slot 2 disabled before rebooting/while booting makes the issue appear

Have an SMS in the Messaging app which is either in ā€œCould not sendā€/failed, or ā€œSending stateā€

STEPS TO REPRODUCE:

1. Insert SIM in Slot 1
2. Disable SIM Slot 2
3. Reboot

EXPECTED RESULTS:

Boot up succeeding cleanly, ofono and related serviices working.

ACTUAL RESULTS:

First thing to notice is that Lipstick, after unlocking, first presents the SIM PIN dialogue.

PIN entry succeeds, but then Lipstick presents the Notification popup

 The name org.ofono was not provided by any .service files

Also, due to ofono not being available, any options re. Mobile Networking are not available in Settings/Top Menu.

Going into console. one can systemctl status ofono and see it failed. systemctl restart ofono results in it booting up, logging some messages that appear like itā€™s successful, and eventually crashing again. (See the logs Iā€™ll upload below.).

Now, going into Flight Mode, and then systemctl restart ofono makes the service come up successfully, and stable. But as soon as Flight Mode is disabled again, it crashes again.

Now, enabling the disabled SIM Slot 2, and systemctl restart ofono does not succeed.

Going into Flight mode again, restart ofono again (this time SIM Slots enabled), and then going out of Flight mode seems to bring up ofono successfully and stable.

MODIFICATIONS:

  • Patchmanager: yes
  • OpenRepos: yes
  • Chum: yes
  • Other: yes:

I have my patch ā€˜Custom SIM Namesā€™ enabled.
Repeating any tests/observations with it disabled does not change any results.

Also, I have systemctl --user mask-ed aml.service.

The first log file, ofono.crash.log is the full (?) journal dump relatively immediately after booting, noticing the failure and going to terminal to see whatā€™s going on.
It includes kernel messages, and shows the coredump.

The other log files, ofono.crash.log{2ā€¦4} are outputs of journalctl -a | grep fono or journalctl -a -u ofono after trying various things.

I tried this with two Jolla C2ā€™s (with not quite 5.0.0.21 in them though) and I was unable to reproduce the problem. I also had a look at Custom SIM Names patch and it shouldnā€™t indeed cause ofono to malfunctionā€¦

You have nemo as the username - thatā€™s quite a feat still! There are some issues we know it causes (some testing devices were flashed back in the nemo days and never flashed since) so Iā€™m suspecting it just might has something to do with this.

Thereā€™s not a lot in the ofono logs, just that it restartedā€¦ You could enable ofono debug logs and inspect that. Note: It contains personal information about your SIM card, so donā€™t just post the tarball here!

If you find anything intresting, you can post snippets of it here, or send it to us privately.

Wellā€¦ :slight_smile:

How I did that is roughly documented here. So itā€™s not a flash-in-ancient-times-and then-update
scenario, itā€™s all manual mangling.
Obviously, with the C2 thatā€™s not possible otherwise.

I guess I could reverse it too if it really makes a difference, but like to be quite subborn in my abhorrence of the default user name.

Thanks for looking - I think so too, but something about it shows up in the logs so I wanted to be transparent about it.

Anyway, my C2 device is in the process of downloading something secret, so I wonā€™t reboot ATM. But Iā€™ll report back after that is done.

#5

Can the SIM card itself play a role in this?

the one Iā€™m using is a bit weird.

Itā€™s new, (bought two or three days ago), and itā€™s from Austrian Budget provider/MVNO ā€œS-Budget Mobileā€.

Now whatā€™s weird about it is that they claim to use T-Mobileā€™s network (called Magenta here), so MCC 232 (Austria) and MNC 03 (T-Mobile).

BUT.

The APN/MMC/SMS configuration that was applied to the Settings app is that of tele.ring (MNC 07).

Actually precisely the settings given in mobile-broadband-provider-info/mobile-broadband-provider-info/serviceproviders.xml at 4a1617295360c10331e748e3a9f42311fbe3325c Ā· sailfishos/mobile-broadband-provider-info Ā· GitHub

Also, if you use their website https://www.s-budget-mobile.at/, while the text makes it clear in many places that the network is T-Mobile/Magenta, the website itself makes a lot of connections to telet.ring named services.

#6

I have added something to the bug report I forgot about: I have a masked aml.service via

nemo@PGJollaC2$ systemctl --user mask aml.service

Could that cause failure?

#7

Affected phone was left over night, ofono service seemed fine, but related options in the UI (statusbar icon, Topmenu icon, Settings section about SIM/mobile network) were not available.

Restarted ofono a couple of times again.
Now at the moment itā€™s running, but only recognizes one SIM slot (acts as if it were a single-SIM device).

#8

Aha! Solved it!

Tl;DR: it seems it was an unsent SMS sticking around in /var/lib/ofono

Background: That SIM is a prepaid one.

After buying it, you have to

  1. Register it/verify yourself on some website (legal requirement)
  2. Top up the prepaid amount (starts with 0)
  3. Select a data/voice plan (switching away from the default plan). Which can among other options can be done by sending SMS to some internal short number.

While 1. and/or 2. has not been done, one can receive SMS from the provider, and do some things like dial *#101# to check the prepaid balance.

Just for kicks I tried sending the ā€œSelect planā€ SMS twice, and some to another phone number of mine.
These messages were either in ā€œFailedā€, or in ā€œSendingā€ state when I rebooted, and this is the pointthe Ofono crashes began.

After I did the below and rebooted, ofono crashes are gone,
Not sure which one of the files was the reason, but it seems fixed now.
Probably itā€™s the tx_queue thing, and the other ones wouldnā€™t have been necessary, too late to check now.

Unticked the solution checkbox because it appeared again.

It can be triggerered by having ā€œundeliverableā€ or ā€œsendingā€ SMS

Thanks a lot! I can confirm your workaround!

EDIT: Simplification!

My symptoms. Basically after failed SMS ofono lose sanity :wink: . So no mobile network at all. Some did report success after many reboots.

I did try to erase that SMS in the app itself but that didnā€™t help!

So command line it is.

  1. First check that this is the proper issue: ofono in failed state.
[defaultuser@JollaC2 ~]$ systemctl --failed

Note that for now lxc@multi-user.service and pulseaudio.service can be in this list for reason unknown to me.

  1. If ofono is listed this seems to be the same bug and you should stop ofono during this process as root:
[defaultuser@JollaC2 ~]$ devel-su
[root@JollaC2 defaultuser]# systemctl stop ofono.service
  1. Then find the newest stuck SMS in nonempty tx queue:
[root@JollaC2 ofono]# ls -lR /var/lib/ofono/*/tx_queue/* | grep -B 2 radio
/var/lib/ofono/293400130011175/tx_queue/0-15-B43D6FFB5F8E9DBA53425680E83862CCA4DA7982:
total 4
-rw-------    1 radio    radio           86 Nov 25 15:42 000

Which in this case is obviously file 000 (name is after time) in 0-15-B43D6FFB5F8E9DBA53425680E83862CCA4DA7982.

Optionally double check itā€™s content (note that due to different codepage in CLI it might seem corrupted):

[root@JollaC2 defaultuser]# cat /var/lib/ofono/293400130011175/tx_queue/0-15-B43D6FFB5F8E9DBA53425680E83862CCA4DA7982/000 
  ļæ½ļæ½61ļæ½eļæ½& pozdrav,
  1. And then remove that file (in this case 000):
[root@JollaC2 defaultuser]# rm /var/lib/ofono/293400130011175/tx_queue/0-15-B43D6FFB5F8E9DBA53425680E83862CCA4DA7982/000
  1. And finally reboot or even faster:
    [root@JollaC2 defaultuser]# systemctl restart ofono.service
    C2 works as before!

[C2] No cellular network - ofonod crashes
#11

Thanks. Works for sometimes, then happens again, so we have to repeat the same process.
Hopefully, Jolla can fix this and provide the updated telephony service soon, because right now it is not reliable.

I am trying to follow up on your steps. I cannot identify anything noteworthy in any tx_queue ! All directories under /var/lib/ofono have empty tx_queue directories, though I know I have some failing SMSes.

#13

Is ofono in fail state?

[defaultuser@JollaC2 ~]$ systemctl --failed

Otherwise itā€™s not the same bug.

#14

No, only the ā€œnormalā€ failures (as I read somewhere else ! Why are they normal to fail at this point in time ?) :

  UNIT                   LOAD   ACTIVE SUB    DESCRIPTION
ā— lxc@multi-user.service loaded failed failed LXC Container: multi-user
ā— pulseaudio.service     loaded failed failed PulseAudio (system-wide mode)
#15

No idea. Question for separate thread.

#16

Deleting the content in the folder was not enough (the problem still appeared with the folder empty, but messages pending for sending in the messages app).

Finally got it back to a working state after deleting everything that is pending, and restarting ofono, then restarting the whole phone.
