Hello.
"Bearer control mode" is added in Release 7 as I am aware of. It's not
vendor specific.
You can check here:
"If Bearer Control Mode is provided by the GGSN in the PCO, the Bearer
Control Mode IE shall be included in order to inform the SGSN about the
bearer control mode and shall indicate the same bearer control mode as
indicated to the MS in the PCO."
Wireshark (I'm using latest version) decodes this information element with
no problem.
There's probably a method to select Release used by GGSN but the GGSN tests
were done on is in a live mobile network and doing configuration changes on
it is not an option.
I will make those changes in these files in a proper way so there's no
confusion what is added and what is deleted (actually nothing is deleted).
I will use git send-email/git format-patch. I suppose the e-mail to send is
the same (osmocom-net-gprs(a)lists.osmocom.org)?
Greetings.

Thanks for your patch!
It looks good in principle, but let's clarify some details.
I can't find the 'Bearer Control Mode' in the GTP spec I have here (ETSI
TS 129
060 V6.9.0 (2005-06) / 3GPP TS 29.060 version 6.9.0 Release 6), so it looks
like a vendor specific extension. You don't happen to have a spec on it?
Your patch includes some unwanted whitespace changes, it would be great to
get
rid of those. I'm marking them below:

The 'if (j...' line shouldn't change.
- iesize = 2;
+ case GTPIE_BCM:
+ iesize = 2;
The iesize line shouldn't change. (x2)
In fact, those whitespace changes look weird, because in the upstream file
version, the indenting you're apparently adding is already present.
It is easiest for us if you submit your patch using git send-email, or at
least
git format-patch, which also ensures that we get a commit log message and
author information, and that the patch is based on our master HEAD.
It would be great if you could resolve these issues. Thanks again!
