Progress of trac->redmine migration
by Holger Freyther
Hi all,
I think we are close to the point of no return. All tickets and wikis have been imported. Please have a quick look if there is something obviously broken and if not I will proceed with post-processing and renaming tonight.
kind regards

License exception for OpenSSL
by Ruben Undheim
Hi,
When running lintian on openbsc, I get the following error:
E: osmocom-bsc-nat: possible-gpl-code-linked-with-openssl
E: osmocom-nitb: possible-gpl-code-linked-with-openssl
It seems like openbsc is being linked with libcrypto from OpenSSL, but I cannot
find any statement of OpenSSL exception for the AGPL. Debian policy requires
this.
Can you look into this? You can have a look at wget if you need an example.

branches: daniel/gprs-iu + sysmocom/cscn = sysmocom/iu; merging to master
by Neels Hofmeyr
The openbsc branches to use for testing IuPS and IuCS have changed,
because Daniel and I have merged the branches.
They used to be daniel/gprs-iu (IIRC) and sysmocom/cscn.
Both are now merged as:
sysmocom/iu
Holger, this is relevant to our coverity configuration.
We are still using other branches that may or may not be merged to their
respective masters. I'd like to publicly record here why or why not we
should merge them now. Please add any reasons you know.
We're using master for Iu[h|CS|PS] in:
libasn1c: * master
libosmo-abis: * master
libosmocore: * master
openggsn: * master
osmo-python-tests: * master
osmo-iuh: * master
Reasons NOT to merge to master in:
openbsc: * sysmocom/iu
- hardcoded kc and sres for testing
- NITB and most probably osmo-bsc are not operational
- A-interface not implemented in CSCN
asn1c: * aper-prefix
- ?
libosmo-netif: * sysmocom/sctp
- ?
libosmo-sccp: * laforge/wip
- ?
Thanks for any additions...

Status of osmocom libraries in Debian
by Ruben Undheim
Hi,
First of all I would like to thank you guys for working on an awesome project
and contributing so much nice code!
I've been working on getting the Osmocom libraries into Debian. libosmocore has
been there for some time now, but I recently also got libosmo-sccp,
libosmo-abis, libosmo-netif, libsmpp34 (not directly osmocom) and openggsn in.
This means that all dependencies for building openbsc, osmo-bts and osmo-pcu
should be available in Debian. I would also like to thank you for keeping a
quite well-maintained debian directory in the tar-balls, even with good state
of SONAME-ing etc. I've used this as the starting point where possible, but
also modified them to meet "Debian standard".
It would be great if you could test the packages and also verify that the
copyright files contain all the copyright holders. Let me know on this list or
on private email if there is something missing or wrong.
Here are links to all copyright files:
https://tracker.debian.org/media/packages/libo/libosmo-abis/copyright-0.3.2…
https://tracker.debian.org/media/packages/libo/libosmo-netif/copyright-0.0.…
https://tracker.debian.org/media/packages/libo/libosmo-sccp/copyright-0.7.0…
https://tracker.debian.org/media/packages/libo/libosmocore/copyright-0.9.0-4
https://tracker.debian.org/media/packages/libs/libsmpp34/copyright-1.10-1
https://tracker.debian.org/media/packages/o/openggsn/copyright-0.92-1
You will have to run Debian sid (unstable) to directly install the packages
using "apt install", but you could also download the .deb-files manually from:
https://packages.debian.org/unstable/[packagename] or for Ubuntu here:
https://launchpad.net/ubuntu/xenial/+source/[packagename]
I'm also aware of that the code is moving ahead rapidly and what is in Debian
unstable now may quickly get out-of-date. But I will try to keep them up-to-
date as much as possible, and also provide backport packages. Getting the
packages in the first time is usually much more cumbersome than keeping them
up-to-date.
For those interested in Ubuntu, the current versions will most likely get
into the next long-term support release (16.04), since its freeze date
for package imports from Debian is already Feb 18th. So let me know quickly
if there is something wrong so that I possibly may be able to fix it before the
freeze (when it's much more straight forward).
Cheers,
Keep up the good work.

[PATCH] Extend L1SAP PH-DATA with presence information
by msuraev＠sysmocom.de
From: Max <msuraev(a)sysmocom.de>
Previously the presence of header and data blocks were communicated
in-band which decreases code readability and makes it unnecessary hard
to add support for new hardware.
Note: both OsmoBTS and OsmoPCU have to be modified to take advantage of
extended ph_data_param structure.

[PATCH] Fix OsmoPCU integration
by msuraev＠sysmocom.de
From: Max <msuraev(a)sysmocom.de>
Add support for explicitly passing PH-DATA presence info.
Remove in-band passing of presence information and replace corresponding
check. This also fixes integration between Octasic BTS hw and OsmoPCU:
previously osmo-bts-octphy have not provided in-band presence
information which cause off-by-one errors and misinterpretation of
ph_data_ind by PCU.
Note: this requires libosmocore version with osmo_ph_pres_info_type
support integrated.

hnbgw should reconnect to CN
by Neels Hofmeyr
Hi list,
during testing of OsmoCSCN, I find that osmo-hnbgw connects to the CN
servers once, but when such a CN component restarts, no new connection is
established. Sequence:
- start hnbgw, which continuously tries to connect to CS and PS CN servers
every five seconds (osmo-cscn and dummy-cn in my case).
- start dummy-cn, hnbgw connects.
- start osmo-cscn, hnbgw connects.
- osmo-cscn segfaults ;)
- hnbgw logs the disconnect
- I restart osmo-cscn
- but hnbgw never attempts to reconnect to osmo-cscn.
- so I have to restart hnbgw, hnb-test and its VTY connection "all the
time", which is cumbersome.
I briefly tried to resolve the issue, but I'm losing patience. I tried to
enable the DLINP debug logging but found that hnbgw's VTY doesn't allow me
to manipulate logging levels, apparently.
Next I'd have liked to set the hnbgw_log_info to indicate
[DLINP] = { .loglevel = LOGL_DEBUG }
but DLINP is negative. Does this really have to be as fiendish?
I guess the INT2IDX() macro doesn't apply here, as it would cause index
overlaps with the other D* constants. It can be really hard to find my way
around the Osmo source code, with the little non-obvious things
accumulating...
I did find that much: the reconnect flag passed to
osmo_stream_cli_open2()
is effective only while state == STREAM_CLI_STATE_CONNECTING, i.e. until a
first connection is established. Now, if upon disconnect, something were
to set the state back to
cli->state = STREAM_CLI_STATE_CONNECTING
my guess is that the cli_timer_cb() would indeed attempt to reconnect as I
intend.
BTW, what does cli stand for? Not command-line interface, is it.
If I stayed onto this I'd probably solve the issue. My focus should be on
an IuCS Location Update though, so comments or help is appreciated :)
So long I'll carry on with the workaround, restarting hnbgw "all the time".
Thanks!

hnb_cs_lu.msc
by Neels Hofmeyr
Hi Harald,
in osmo-iuh/doc/hnb_cs_lu.msc I find that after the location update
request from the UE, an identity request "should" follow from the CN.
Yesterday I made my first pcap using our hNodeB and that weighty black UE
we use for testing, and saw that the MSC indeed sends out an identity
request at that time [1], however, the UE simply never responds to it.
My question: is the hnb_cs_lu.msc declarative and definitely correct, or
could it be that in 3G, UEs in general expect authentication first, as
the "osmo-iuh/pcap/UPP RANAP.pcap" suggests (starting at packet #335).
Since my sources tell me (i.e. Daniel) that an identity request at that
time is indeed kinda special practise by openbsc to collect all IMEIs we
possibly can, I'm going for authentication first.
Just wanted to make sure you agree that the hnb_cs_lu.msc may be erratic
in that case. Thanks!

libasn1c config.h
by Neels Hofmeyr
Hi,
you may be aware that the '#include "config.h"' in libasn1c's asn_system.h
breaks builds with the out-of-the-box 'make install'. So far we go to the
installed header and remove that line.
This time I've removed the line from the source tree before building, and
I can't find any effect really. My source tree has no config.h file to
begin with.
But I'm not sure what would be a point of failure there. When I commit
this, will I break something I merely happen to not be using? Any autoconf
guru here that could resolve this with a quick glance?

I'm a bit out of touch with OVS, so my idea on how this should work might be wrong.
As far as I understand OVS, the way forward would be to use the lwtunnel infrastructure to enable OVS to use a kernel GTP module.
Our current OVS module ([1], [2]) is not (yet) using lwtunnel, but we do plan on switching to that.
So far, we have been coordinating the GTP kernel module development on the OpenBSC ML [3]. The goal is to upstream it as soon as all the
basics are covered (smallish netlink API changes, final touches on IPv6 and maybe lwtunnel).
On the OVS side, someone would then need to implement the necessary ops to handle GTP lwtunnel integration.

MSC split: is_siemens_bts() in libmsc/gsm_04_08.c / conn->bts vs. lchan->ts->trx->bts
by Neels Hofmeyr
I'm trying to get rid of all BTS backpointers in libmsc.
In libmsc/gsm_04_08.c, in gsm48_rx_mm_serv_req(), I find:
if (is_siemens_bts(bts))
send_siemens_mrpci(msg->lchan, classmark2-1);
My conclusion so far is that this "hook" should move to the BSC code, but
I could use some comforting approval by more apt contenders... Some
detail:
send_siemens_mrpci() is found in libbsc/gsm_04_08_utils.c:
int send_siemens_mrpci(struct gsm_lchan *lchan,
uint8_t *classmark2_lv)
{
struct rsl_mrpci mrpci;
if (classmark2_lv[0] < 2)
return -EINVAL;
mrpci.power_class = classmark2_lv[1] & 0x7;
mrpci.vgcs_capable = classmark2_lv[2] & (1 << 1);
mrpci.vbs_capable = classmark2_lv[2] & (1 <<2);
mrpci.gsm_phase = (classmark2_lv[1]) >> 5 & 0x3;
return rsl_siemens_mrpci(lchan, &mrpci);
}
IIUC the Siemens BS11 BTS needs to be tickled with a vendor-specific RSL
message as soon as a CM service request (GSM48_MT_MM_CM_SERV_REQ) or a paging
response is received from a subscriber.
Only the BSC knows which BTS is involved, so I'd try to find some place in
libbsc/ or osmo-bsc/ to move this away to.
The same function is called from gsm48_handle_paging_resp() in libbsc.
Any shortcuts / workarounds or could this also be dropped entirely?
It does look like that particular case is indeed missing from osmo-bsc.
Who is this Mister PCI anyway? ;)
The gsm48_handle_paging_resp() function leads me to another, more general
question: often, there are two bts pointers around, namely the
gsm_subscriber_connection->bts
as well as the
lchan->ts->trx->bts
Are these typically/always/never expected to be the same bts struct?
(In this function, both bts pointers are used, and I'd like to understand why.)
Thanks!

EDGE over osmo-pcu
by Jacob Erlbeck
Hi everybody,
we have just done the first download of an Internet page using the
current bleeding EDGE development version of the OSMO-PCU. Supported are
MCS-1 to MCS-9 in downlink and MCS-1 to MCS-4 in uplink direction.
The download of 'www.osmocom.org' has been documented in a PCAP file and
can be downloaded from
https://openbsc.osmocom.org/trac/wiki/osmo-pcu
To decode the data blocks, an experimental patch for the gsmtab
dissector is also available from there.
Cheers
Jacob

libosmocore does not build in Ubuntu
by Ruben Undheim
Hi,
Can someone here help me debug the failing build of libosmocore in Ubuntu?
See:
https://launchpadlibrarian.net/235791225/buildlog_ubuntu-xenial-amd64.libos…
The test case "gprs-bssgp" fails with following output:
stderr:

Unable to resolve NSEI 4660 to NS-VC!
Assert failed rc >= 0 gb/gprs_bssgp_test.c:234
I think it is related to the hardening option "-D_FORTIFY_SOURCE=2". What is
interesting is that it builds correctly in Debian, but not Ubuntu.
The issue has apparently been observed before:
http://comments.gmane.org/gmane.comp.mobile.osmocom.baseband.devel/4149
If this gets fixed quickly, it might go into the next Ubuntu LTS version which
has import freeze Feb 18th.

[PATCH 1/3] log: Add log_check_level function
by Jacob Erlbeck
This commit adds this predicate function which can be used to
avoid the execution of code if a certain log level is not enabled.
The function will only return 0 (false), if it is sure that a logging
call for the same facility and level will not produce any output.
This safety criterion shall ensure, that no logging output is lost
due to the use of this predicate as a guard. On the other hand, even
if the predicate returns != 0 (true), no logging output might get
generated by a similar logging command.
Note that the current implementation is not focussed on performance,
which could be improved by using a lookup table instead of iterating
through every target.

2G vs 3G LACs
by Neels Hofmeyr
Hi folks,
to share a finding: the question was whether 2G and 3G cells may share location
area codes.
A glance at some (mostly anonymized) live data from GSM cell monitoring
hardware, in use by one of our customers, answers that quite clearly:
Network MCC MNC LAC CID Type Band
FirstOperator 123 4 678 C669 GSM GSM900
FirstOperator 123 4 678 CF5A GSM GSM900
FirstOperator 123 4 678 CF2A GSM GSM900
FirstOperator 123 4 678 C695 GSM GSM900
FirstOperator 123 4 678 CF30 GSM GSM900
FirstOperator 123 4 678 CF58 GSM GSM900
FirstOperator 123 4 678 6869 UMTS UMTS2100
FirstOperator 123 4 678 C69B GSM GSM900
SecondOperator 123 5 9AB DEEF GSM DCS1800
SecondOperator 123 5 9AB E15D UMTS UMTS2100
SecondOperator 123 5 9AB E163 UMTS UMTS2100
SecondOperator 123 5 9AB E080 GSM DCS1800
LACs are shared across 2G ("GSM" here) and 3G ("UMTS") technologies, only the
cell IDs are guaranteed to differ.
Happy hacking,
~Neels

UE <--> CN connections in 3G
by Neels Hofmeyr
Hi all,
this is diverting a mail dialog that started off privately to this list,
for the benefit of everyone.
You may have noticed that Daniel is working on IuPS (3G/UMTS data conns)
and I'm working on the OsmoCSCN, which is going to handle IuCS (3G/UMTS
voice calls).
There was still some puzzlement around connection IDs and how to reach a
mobile device (aka UE). In particular, which ID or information do I store
to identify the link to a UE, and how do I find a UE in case of paging?
First off, we're so far implementing a special case where we're using a
HNB-GW to demultiplex voice and data (IuCS and IuPS) from an hNodeB
(femto-cell). ASCII art to illustrate, view in a monospaced font:
UE 1 <--> |hNodeB 1| <-->|HNB-GW| <---> |CSCN or SGSN
| 1 | |
UE 2 <--> |hNodeB 2| <-->| | |
UE 3 <--> | | | |
|
|
UE 4 <--> |hNodeB 3| <-->|HNB-GW| <---> |
| 2 | |
UE 5 <--> |hNodeB 4| <-->| | |
UE 6 <--> | | | |
So, how does a CSCN know where to send a message for a given UE, and how
does it reach that UE?
Turns out the picture is more like this:
. . . (hNodeB) . . . (HNB-GW)
UE1 <--> | Cell <--1--> [RNC] <------------> [CSCN]
UE2 <--> |
Meaning that the hNodeB actually encloses an RNC (Radio Network
Controller) and a single radio cell. The HNB-GW does pretty much
"invisible" forwarding of the SCCP|SUA connection to the RNC. Each RNC has
a global RNC ID, and can manage N radio cells. In the hNodeB case, there
is exactly one cell behind the RNC, but the general case looks like this:
UE1 <--> | Cell <-----> |RNC1 <------------> |CSCN
UE2 <--> | | |
| |
UE3 <--> | Cell <-----> | |
|
|
UE4 <--> | Cell <-----> |RNC2 <------------> |
UE5 <--> | | |
| |
UE6 <--> | Cell <-----> | |
When a UE calls, the CSCN receives a User SAP link with a conn_id, and
simply routes the reply back to this link and conn_id. The reply goes
right back to the RNC, and the RNC knows which cell the UE is at.
The case where the CN contacts a UE is known as paging, i.e. the request
by the CN that the UE shall please establish a connection to the CN. The
CSCN may encounter different cases here: a User SAP link may have been
established and is still present, or no link is available (e.g. a link has
existed before but has been torn down due to a Reset by the RNC, etc.).
If the link is still valid, this manifests as: the struct
gsm_subscriber_connection still has a valid pointer to an osmo_sua_link,
and iu_tx() feeds the conn_id to this link to reach the UE.
(Note that the gsm_subscriber_connection struct does not yet have an
osmo_sua_link pointer. I will move the ue_conn_ctx into the
gsm_subscriber_connection struct in an upcoming commit.)
If, e.g. due to a Reset, the osmo_sua_link pointer has been cleared, the
CSCN or SGSN will ask the HLR: where has the last location update for this
IMSI been registered? Each RNC can manage several location areas, further
divided into several service areas, and once the HLR has identified the
service area where the UE is expected, the CSCN or SGSN can identify the
RNC by the global RNC ID and send the paging request in that direction.
A bit of pseudo struct code:
struct gsm_network {
llist of struct gsm_subscriber_connection:
{
{
struct gsm_subscriber subscr {
char imsi[GSM_IMSI_LENGTH];
};
struct {
struct osmo_sua_link *link; /* point into an rnc struct */
uint32_t conn_id;
} iu;
},
...
};
llist of struct rnc (does not exist yet) :
{
struct osmo_sua_link *link; /* upon link-down, clear the above */
...
};
};
So, IIUC, the global RNC ID resolved from the HLR info should identify the
path to a particular UE. The CSCN knows which RNC is behind which of its
local link endpoints. In our special case with an HNB-GW and when there
are several hNodeB instances behind the HNB-GW, the HNB-GW knows which way
to send a connection reply by the established SCCP|SUA link, or which way
to send a paging request by the RNC ID. The finer code details here are
not entirely known to me yet, but I hope that the answers will come
naturally or have already been implemented by Daniel ;)
If any questions, answers or comments emerge in your mind while reading
this, please don't hesitate and share!
Thanks,

statsd usage
by Max (☭)
Hi.
There are bunch of functions like osmo_counter_* and osmo_stats_reporter_* in
libosmocore and other projects.
I'm pretty much understand what they do, but what happens on the receiving end?
There's nothing in our wiki regarding statsd.
How do you guys use it? Any statsd config examples? Workflow hints?
With such an elaborate functionality there got to be somebody who actually uses it.
Please share your experience, configs, pretty screenshots and complaints :)
cheers,
Max.

[PATCH 1/3] Introduce new phy_link and phy_instance abstraction
by Harald Welte
This way we can model a flexible mapping between any number of PHYs,
each having multiple instances, and then map BTSs with TRXx on top of
those PHYs.

+== OsmoBTS PHY interface abstraction
+
+The OsmoBTS PHY interface serves as an abstraction layer between given
+PHY hardware and the actual logical transceivers (TRXs) of a BTS inside
+the OsmoBTS code base.
+
+
+=== PHY link
+
+A PHY link is a physical connection / link towards a given PHY. This
+might be, for example,
+
+* a set of file descriptors to device nodes in the /dev/ directory
+ (sysmobts, litecell15)
+* a packet socket for sending raw Ethernet frames to an OCTPHY
+* a set of UDP sockets for interacting with OsmoTRX
+
+Each PHY interface has a set of attribute/parameters and a list of 1 to
+n PHY instances.
+
+PHY links are numbered 0..n globally inside OsmoBTS.
+
+Each PHY link is configured via the VTY using its individual top-level
+vty node. Given the different bts-model / phy specific properties, the
+VTY configuration options (if any) of the PHY instance differ between
+BTS models.
+
+The PHY links and instances must be configured above the BTS/TRX nodes
+in the configuration file. If the file is saved via the VTY, the code
+automatically ensures this.
+
+
+=== PHY instance
+
+A PHY instance is an instance of a PHY, accessed via a PHY link.
+
+In the case of osmo-bts-sysmo and osmo-bts-trx, there is only one
+instance in every PHY link. This is due to the fact that the API inside
+that PHY link does not permit for distinguishing multiple different
+logical TRXs.
+
+Other PHY implementations like the OCTPHY however do support addressing
+multiple PHY instances via a single PHY link.
+
+PHY instances are numbered 0..n inside each PHY link.
+
+Each PHY instance is configured via the VTY as a separate node beneath each
+PHY link. Given the different bts-model / phy specific properties, the
+VTY configuration options (if any) of the PHY instance differ between
+BTS models.
+
+
+=== Mapping PHY instances to TRXs
+
+Each TRX node in the VTY must use the 'phy N instance M' command in
+order to specify which PHY instance is allocated to this specific TRX.

Cosmetic early RTP sending issue and please test
by Holger Freyther
Hi,
before the l1sap changes were merged I fixed a case where after a ip.access CRCX with recvonly mode the BTS would already start to send RTP frames to UDP port 0 which will trigger an ICMP unreachable. This is not harmful but still a bug. After the l1sap merge the sysmobts is still doing it when it receives a TCH frame and all other bts models behave like before the bugfix. The below diff copies this into the common code.
Besides administratives work I try to work on the SMSC, so if anyone could testdrive this patch and check for ICMP errors it would be greatly appreciated.

[PATCH 0/3] Fix handling PDP update messages
by Daniel Willmann
From: Daniel Willmann <daniel(a)totalueberwachung.de>
Hello,
it seems PDP context updates was never really used/tested to an Update PDP
context would not go through. The following patches fix that (at least for
gtpv1).
Regards
Daniel
Daniel Willmann (3):
gtp: Pass pdp along when calling gtp_req() in gtp_update_context()
gtp: Make gtp_update_pdp_conf() work for gtp0 and gtp1 connections
gtp: Handle gtpv1 in gtp_update_pdp_conf() correctly

[PATCH 1/3] Introduce new phy_link and phy_instance abstraction
by laforge＠gnumonks.org
From: Harald Welte <laforge(a)gnumonks.org>
This way we can model a flexible mapping between any number of PHYs,
each having multiple instances, and then map BTSs with TRXx on top of
those PHYs.

[PATCH 1/7] TRX: factor out the scheduler from remaining code
by laforge＠gnumonks.org
From: Harald Welte <laforge(a)gnumonks.org>
The L1 scheduler is a generally useful component that is unfortunately
tied quite a bit into the OsmoTRX support. Let's try to separate it out
by having separate per-trx/per-ts/per-chan data structures pre-fixed
with l1sched_
Using this patch it should be one step easier to use the scheduler for
other BTS models, such as the intended upcoming virtual BTS.

LCR segfault on SIP invite
by OMAR RAMADAN
I'm using LCR as a GSM <-> SIP interface and I've been trying to figure out
why MO calls result in a segfault. I am running openbsc on cdc548cb and LCR
on c14326641a built and run on an ubuntu 14.04 64bit.

malformed.
Has anyone seen this problem before? Would appreciate pointers.
