Fix spelling dublicate -> duplicate in comments and in (apparently only
statically used) gtp_dublicate().

Fix: the code handles fd1u but prints fd1c.

It would print the memory location of the address buffer. Instead, print the
human readable host address and port.
The current code base supports only IPv4, and thread safety is apparently not
required, hence just use inet_ntoa(). (The IPv6 and thread capable version is 4
times longer and harder to read.)

Make libgtp depend on libosmocore and use the generic logging
infrastructure for it.

Encapsulate code to handle the teid with GTPv0.
|
|
This field needs to be in network byte order as well.

this fixes some compiler warnings

After so many years of silence, we don't expect the original author to
return to the project. To make things a bit simpler for us, we convert
the coding style to what we are used to (Linux style).
The conversion was made using the 'Lindent' script which is part of the
Linux kernel.

According to 3GPP TS 29.060 recovery is optional, add command line option --norecovery to remove this field in sgsnemu

I use OpenGGSN to create/update/delete PDP context and I found a bug
in the implementation: when the sgsnemu sends an "update PDP context"
request, it receives back a "create PDP context" response. Below is
the correction I made, I hope it helps.

The cb_recovery() callback enables the user application to detect
a change in the restart counter and thus start the appropriate
recovery procedures.
|
|
This adds support for the followng new GTP Information Elements:
RAT_TYPE, USER_LOC, MS_TZ, IMEI_SV
Furthermore, it allows to specify those fields as sgsnemu command line
arguments.

in front of Cisco and Alcatel GGSN's, we meet the following error :
5 packets transmitted
Disconnecting PDP context #0
openggsn[24940]: gtp.c: 2417: Unexpected cause value received: 193. Packet from 172.29.5.130:2123, length: 14, content: 32 15 00 06 00 00 00 01 04 02 00 00 01 c1
it is because in the sgsnemu requests packet, the teardown field is after the NSAPI field :
