nokia-modem (N900) not detected after migration to udevng

nokia-modem (N900) not detected after migration to udevng

[Clayton Craft]

[-- Attachment #1: Type: text/plain, Size: 689 bytes --]

Hi,
I've been debugging why the n900 modem is not recognized by ofono
for a few days now, and have determined that the cause is because the
calls in udevng to udev_device_get_devnode return NULL. It seems that
the nokia-modem driver does not create any device nodes under /dev.

This seems to be a regression in functionality since the move to
udevng as previous versions of ofono seem to detect the n900 modem
correctly (right before this commit 3ac449e25fc8cb9880c48b8f309189c6a644f200)
This issue occurs from this commit onwards, including the latest commit
as of this mail.

What bus does this modem sit on?  Are you running ofono _on_ the N900 or 
are you trying to tether the N900 to some system with ofono?

If you are tethering, what udev events do you get when you plug in the 
modem?  Try running "udevadm monitor" and watch what happens when you 
plug the modem in.

Not getting a device node sounds mostly like there's a driver missing, 
though...

This is on HSI bus. I am running ofono on the N900 (not tethering).

From what I understand, I am loading all of the necessary drivers for
this to work (nokia-modem, which pulls in its dependencies
automaticall). 
As I stated in my original note, before moving 'legacy
device' initialization to udevng, ofono would at least 'see' the
modem. The test script 'list-modems' would list it, now it does not
list anything.

OK, from what I understand, you should be able to find this device under 
/sys/class/net/....

See if you can find the device there and run:

udevadm info --query all --path /sys/class/net/....
and
udevadm info --attribute-walk --path /sys/class/net.....

Post that output here if it's sane so that we can see what info udev is 
giving you for the device.

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

OK, good.  It's not a driver issue in any case.  Now we need to figure 
out why ofono is rejecting the device.  The debug output from ofonod 
would be useful.  Try running ofono as:

ofonod -d -n

and paste the output here.

Re: nokia-modem (N900) not detected after migration to udevng

[Clayton Craft]

[-- Attachment #1: Type: text/plain, Size: 7426 bytes --]

Ok so after applying the two patches submitted by Jonas, I can get a
little further, but it appears that init is still failing:

ofonod[12522]: plugins/udevng.c:create_modem() /sys/devices/platform/68000000.ocp/48058000.ssi-controller/ssi0/port0/n900-modem

ofonod[12522]: src/modem.c:ofono_modem_create() name: (null), type: n900
ofonod[12522]: plugins/udevng.c:destroy_modem() /sys/devices/platform/68000000.ocp/48058000.ssi-controller/ssi0/port0/n900-modem
ofonod[12522]: src/modem.c:ofono_modem_remove() 0x622770
ofonod[12522]: src/private-network.c:ofono_private_network_driver_register() driver: 0x60f334, name: Example Private Network Driver


After poking around in gdb, I've determined that this condition is failing:
from setup_isi_modem in plugins/udevng.c:
        if (g_strcmp0(udev_device_get_subsystem(info->dev), "net") != 0)

It looks like the modem->serial object does not have any valid data. The
cstrings in that struct contain gibberish. info->dev is NULL, and other 
info members are not valid strings and definitely do not represent what they 
should. I added a DBG() print of them here to demonstrate:
ofonod[12905]: plugins/udevng.c:setup_isi_serial() **devpath: `aX, devnode: (null), subsystem: X

Hi Clayton,

Give this patch a try and see if things look better.

Hi Jonas,

This looks MUCH better!! Just to re-cap, it took the application of
all three of the patches you sent over to get this to finally come up.

Oh, wow, that's a bit of a downer.. but thanks for the info. Is there
a reason the ISI RFC patch you mentioned there was not merged?

Would it be possible to merge the three patches that Jonas produced,
so at least the modem will make it through the initialization phase? I
will take a long, hard look at some point into the patchset you linked
in your other mail, and one day I might try to fix it, but being able
to avoid the previous init problems when that day comes would be really nice :)

[PATCH 1/1] isimodem: Use correct callback for pin status

[Clayton Craft]

[-- Attachment #1: Type: text/plain, Size: 1352 bytes --]

This fixes the segfault I experienced on enabling the modem by using
the correct callback for pin status response.

check_sec_response is used when entering / enabling / disabling a PIN. 
So you might be hacking around your particular issue, but breaking others.

The real fix is to implement a proper callback for isi_query_locked. 
The previously submitted (2010 or so?) driver code might give you hints 
on what the actual callback should look like.

Hi Denis,
Ah, ok, I think see what you mean. Sorry for the misunderstanding, and thank
you for your patience. I have now implemented a proper query method
based on the 2010 patch you referenced. I don't have a PIN set on my
SIM, but it seems to allow the 'enabling' to proceed successfully and
based on my understanding of what the 2010 patch is doing, allow for
signaling if a SIM is locked as well.

[PATCH 1/2] udev: fixes for detection of non-USB modems

[Jonas Bonn]

[-- Attachment #1: Type: text/plain, Size: 1960 bytes --]

This patch fixes up some fallout from the merging of the udev and udevng
modules.

i)  The 'serial' modems in question are not necessarily serial modems at
all; for example, the N900 ISI modems appear as network devices and don't
have a devnode.  This patch relaxes the requirement that a devnode exist.

ii)  The modem driver was being set to 'legacy', which is a remnant of
an earlier approach to merging these modules.  The driver needs to be
properly set to the value of the OFONO_DRIVER property in order for the
setup function to be found.

iii)  The serial modem's private data was being added to the modem
structure incorrectly...

In particular point iii) above shows that there is essentially nobody
using these devices which makes modifications in this area tricky.

[PATCH 1/1] udev: devnode is not a required modem property

[Jonas Bonn]

[-- Attachment #1: Type: text/plain, Size: 1182 bytes --]

A devnode does not always exist; the Nokia N900, for example, does not
provide one for its modem.

This patch relaxes the check on device properties to exclude the
requirement of a devnode.

The "Device" property is not used by the n900 or u8500 drivers, so drop
setting this property when setting up these devices.

Hi Clayton,

Could you try this patch and see if the N900 is detected?

Thanks,
Jonas

Re: [PATCH 1/1] udev: devnode is not a required modem property

Hi Jonas,
I have tested the patch, looks like initialization gets a little
further but it seems that ofono gives up and removes the modem. The
'list-modems' test script doesn't show the modem after launch. Here's
the output from "ofonod -nd" using your patch:

[PATCH 1/1] udev: set driver for serial drivers

[Jonas Bonn]

[-- Attachment #1: Type: text/plain, Size: 1027 bytes --]

The switch away from udev.c to udevng.c for serial modems ended up
having a hardcoded driver "legacy" set on them.  This breaks as the
setup routine for the device will never be found this way.  This patch
sets the correct driver for the device.

Hi Clayton,

Here's another patch that hopefully gets the N900 a bit further down
the road to initialization.  Apply this _on top of_ the earlier patch
I sent you; they are both needed.

Cheers,
Jonas

Hi Jonas,
I applied the patch below after the first patch, looks like I inched
ahead a little further but something is still causing udevng to give
up and tear everything down (output clipped to include only changes
from the last attempt before this patch):
