[PATCH_v4 0/5] Private network request to ConnMan
by Guillaume Zajac
Hi,
Changelog from v3 is:
- Add private-network source/include
- ConnMan plugin is independant from emulator
- Each application that need VPN will pass a callback as argument
when private network is requested. This callback will contain the
private network settings.
Guillaume Zajac (5):
gatppp: Add new contructor to use external fd
private-network: add callback typedef drivers and settings
private-network: add request/release functions and new feature to
Makefile.am
emulator: add request/release private network calls
connman: add plugin in oFono to request request/release private
network

ofono with sim5320 module
by David Ashley
Hello, I'm at my wits' end trying to get ofono working with the
sim5320 module. I'm using the plugins/sim900.c module as a starting
point. I think the issue has something to do with the difference
between the MUX functionality between the 900 and the 5320. The sim900
supports the elaborate parameters sent on the
AT+CMUX=0,x,x,x,x, etc.
but the SIM5320 only supports
AT+CMUX=0
There's that... but also the way the sim900 plugin creates a
SETUP_DLC, initiates muxing, then deletes the setup DLC and creates 4
new DLC's... it didn't work for the sim5320 until I remapped the DLC's
somewhat like this:
#define NUM_DLC 4
#define VOICE_DLC 2
#define NETREG_DLC 1
//#define SMS_DLC 2
#define GPRS_DLC 3
#define SETUP_DLC 0
static char *dlc_prefixes[NUM_DLC] = {
[VOICE_DLC]="Voice: ",
[NETREG_DLC]="Net: ",
// [SMS_DLC]= "SMS: ",
[GPRS_DLC]= "GPRS: " ,
[SETUP_DLC]= "Setup: ",
};
Note I have to eliminate the SMS_DLC usage later in sim5320_post_sim:
// ofono_sms_create(modem, OFONO_VENDOR_SIMCOM, "atmodem",
// data->dlcs[SMS_DLC]);
OK everything is *ALMOST* working. ofonod interacts fine with
connmand, connmand tells ofonod to activate the sim5320, which
actually establishes a ppp connection and sets up a ppp device:
ppp0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-0
inet addr:30.97.132.47 P-t-P:30.97.132.47 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:2 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:500
RX bytes:0 (0.0 B) TX bytes:124 (124.0 B)
Here's the rub: No matter what I do, I never get any RX packets from
that ppp device, and even when it appears to TX packets (I'm trying to
ping out) the machine on the internet isn't actually receiving them.
I'm running on a beaglebone with a custom board with a sim5320 module on it.
I have no idea what to try... Any advice would be appreciated...
Thanks very much!!!!

[RFC hwdb v1 00/28] USB interface labelling via udev
by Jonas Bonn
This series moves the labelling of USB modem interfaces to udev proper.
For most modems we are able to use the udev hwdb to do the labelling, and
for a few special cases we need to add udev rules.
Importantly, the OFONO_DRIVER and OFONO_LABEL properties are set on all
known interfaces. This saves the ofono udev handler from having to figure
these out from parsing udev device properties and doing table lookups.
The reason for doing this is:
i) ofono is currenly re-creating a lot of udev functionality when trying
figure out the driver and label to apply to interfaces
ii) the udev hwdb is an optimized path for setting device properties
iii) labelling interfaces via udev means it can be done for new devices
without code changes (and thus without rebuilding ofono)
iv) the udev implementation gets smaller and simpler; hopefully this
can be made so generic that every new modem won't require changes
to this module
This is an RFC because I'm not quite done with the conversion yet. There
are still some sysattr details to work out for the mbm and telit modems;
and the qmi modems still need to be put into their final form. A follow-up
series will be sent to this one but I wanted to get this sent out now for
some review.
Thanks,
Jonas

[PATCH] qmi: track discovery tasks so clean up is possible
by Denis Kenzior
There are various device & service discovery tasks that are initiated
based on a qmi_device object. qmi_device object does not currently
keep track of these tasks. Unfortunately the qmi_device object can
go away at any time, and these tasks can become orphaned.
The result of this can lead to crashes. E.g. a discovery task timeout fires
after the qmi_device object has been destroyed. Since the object is no
longer valid, any accesses to it will likely result in a SEGFAULT.
This patch attempts to track all discovery tasks on the qmi_device
object itself, so that they can be cleaned up properly. This patch does
not handle the qmi_device_shutdown functionality.

[PATCH] qmimodem: include shutdown in callback cleanup queue
by Lukasz Nowak
From: Lukasz Nowak <lnowak(a)tycoint.com>
Create a unified callback_data structure, used for all timeout callbacks.
This allows to maintain a single callback_queue, which cancels any active
timeouts, and frees callback data memory when a usb device is hot unplugged.

[PATCH v3] atmodem: telit - re-attach gprs automatically
by Lukasz Nowak
From: Lukasz Nowak <lnowak(a)tycoint.com>
Telit AT modem firmware (tested with UE910-EUR) generates
+CGREG: 0\r\n\r\n+CGEV: NW DETACH
after a context is de-activated and ppp connection closed.
Then, after a random amount of time (observed from a few seconds
to a few hours), an unsolicited +CGREG: 1 arrives.
Attempt to fix the problem, by sending AT+CGATT=1 once.
This does not re-activate the context, but if a network connection
is still correct, will generate an immediate +CGREG: 1.

[PATCH udev v3 0/5] Device handling cleanups
by Jonas Bonn
This is version 3 of the udev handling cleanups.
Changes since v2:
* Addressed comments from Denis
Changes since v1:
* Reworked patch 1/5 (was 11/15) to handle 'legacy' devices in a simpler
manner.
* Addressed comments from Denis
Original blurb follows:
This is a series of incremental cleanups to the libudev device handling
code.
- the early patches in the series are all good cleanups that can be
taken irregardless of whether the last patches are desired
- the last patches are more intrusive as they attempt to move the
functionality of udev.c into udevng.c
Somebody with access to old hardware really needs to take a look at
this series to see if the migration to udevng works properly. I do
not have any such hardware, myself. I suspect that there's not many
such devices in circulation; my hope is that this legacy code works
for now and can be ripped out in time.
In any case, if someone has such old hardware, hopefully these changes
are sufficiently correct that the last bugs can shake themselves out
easily... we'll see.
Jonas Bonn (5):
udevng: add serial device handling functions
udevng: match on the hsi subsystem for legacy devices
udevng: hook up legacy devices
udevng: get properties from interface
plugins: remove udev module

[PATCH v2] qmimodem: add protection against modem_unregister
by Lukasz Nowak
From: Lukasz Nowak <lnowak(a)tycoint.com>
The qmimodem driver sets up numerous timeouts, passing internal
data structures to them as user_data. If a physical modem device
is removed, udev will call modem_unregister, which in turn will
call gobi_remove(). That function calls qmi_device_unref() which
frees all internal data structure memory inside qmidriver.
If a timeout is in progress while the usb device is removed,
the callback function will operate on already freed memory,
causing unpredicatble results. In some cases nothing bad will
happen, in others - segfault.
In order to solve this problem, store all created timeouts in
a list, and when the driver data is freed in qmi_device_unref()
remove all active timeout sources.

[PATCH v2] atmodem: telit - re-attach gprs automatically
by Lukasz Nowak
From: Lukasz Nowak <lnowak(a)tycoint.com>
Telit AT modem firmware (tested with UE910-EUR) generates
+CGREG: 0\r\n\r\n+CGEV: NW DETACH
after a context is de-activated and ppp connection closed.
Then, after a random amount of time (observed from a few seconds
to a few hours), an unsolicited +CGREG: 1 arrives.
Attempt to fix the problem, by sending AT+CGATT=1 once.
This does not re-activate the context, but if a network connection
is still correct, will generate an immediate +CGREG: 1.
