[PATCH v2 0/4] Add a driver for Quectel UC15 modems
by Philip Paeps
Changes since v1:
o Ammended udevng probing to also catch the modem when no
labels have been configured in udev rules.
o Reworked the enable/retry mechanism to be a little bit less
hackish. Commented the rationale in quectel_enable().
o Use prefixes to help the AT parser match queries to replies.
o Fixed style issues and unnecessary casts.
o Make enable() end up in CFUN=4 (powered but radio off).

[PATCH] hfpmodem: Fix crash with more than two calls
by Sergio Checa Blanco
From: Sergio Checa Blanco <sergio.checa(a)bmw-carit.de>
A periodic CLCC polling is started when there is an ongoing multiparty
call and a new call appears in the system. A simple way to reproduce
the crashing scenario is:
1. Place a call.
2. Place a second call.
3. Create a multiparty call with both calls.
4. Place a third call (incoming or outgoing does not matter).
5. Disconnect HFP from the modem.
Within the function ciev_callheld_notify, the AT+CLCC command is also
invoked, thus a new cyclic CLCC polling is started, and it overwrites
the timer resource identifier stored in voicecall_data.clcc_source.
This means that there are several timers doing the CLCC polling, but
only one of those is under control, i.e. it can be removed through its
source identifier, hence a timer source leak.
This has a fatal consequence when the HFP modem is disconnected. The
function hfp_voicecall_remove stops the timer that is under control
before freeing the voicecall_data struct. However there are other timers
that are still active and will execute its handler poll_clcc afterwards.
Inside poll_clcc the driver_data is accessed, which is already NULL.
A solution for this is to avoid starting a CLCC polling if there is
already one active, i.e. clcc_source is not 0. By doing this the
uncontrolled timers will not cycle forever.

[PATCH 0/6] Add a driver for u-blox modems
by Philip Paeps
This set of patches adds basic support for u-blox modems. It has only
been tested with a u-blox SARA U270 modem but judging from the datasheet
it should be fairly trivial to adapt to other variants of the SARA, LISA
and LEON chips.

[PATCH 0/3] Provision the PPP authentication method from mbpi
by Philip Paeps
My patch to the mobile-broadband-provider-info database DTD to add an
attribute indicating the authentication method to use was accepted by
the maintainers[1] and merged in their tree[2].
This set of patches adds support for the new attribute in the mbpi
plugin so new GPRS contexts can be correctly provisioned. If the
authentication method is unspecified in the mbpi database we default
to CHAP (i.e.: previous behaviour).

[PATCH] hfpmodem: Split AT+VTS command into multiple +VTS
by Sergio Checa Blanco
From: Sergio Checa Blanco <sergio.checa(a)bmw-carit.de>
According to the standard "3GPP 27.007 v6.8.0" Appendix C.2.11,
when sending multiple DTMF characters, these must go in individual
+VTS commands for each tone. This adopts the AT modem approach.
Before: AT+VTS=1234\r
After: AT+VTS=1;+VTS=2;+VTS=3;+VTS=4\r

[PATCH] Add support for PAP authentication
by Philip Paeps
Some operators require PAP authentication instead of the more prevalent CHAP.
This is particularly true in the case of private APNs for machine to machine
communication.
These patches add support for PAP in the PPP library and glue for configuring
and provisioning contexts to use it. The default is still to use CHAP, so
current behaviour shouldn't change unexpectedly.

Contribution: Telit HE910 modem with single serial + CMUX configuration
by Frederik Lotter
Hi Guys,
I have done some work to add support for a Telit HE910, but configured to
use a single serial connection which will then enable additional ports
using CMUX. I made the changes against v1.14 and rebased the commit against
master.
If this could be of use to the project please feel free to add it. I have
successfully used the driver to establish an internet connection with
Connman. Note however that SIM detection does not properly work as I need
to remove and re-insert the SIM (but I experienced this even with the
original HE910 driver).
Unfortunately we are moving to a new modem from uBLOX so I need to redo the
work and I cannot spend more time on this right now. I hope to contribute
the uBLOX code later on.
Kind Regards,
Frederik Lotter
