OsmoDevCon 2018 schedule planning

by Harald Welte

Dear Osmocom Community, [please respect the Reply-To and post all follow-up discussion to this to openbsc(a)lists.osmocom.org, so we avoid having long threads cross-posted to several mailing lists.] Like every year in early December, it is time to discuss as schedule for OsmoDevCon in the upcoming year. Note: Ths is about OsmoDevCon, the more private meeting of developers, *NOT* about OsmoCon, the public conference. == When, Who, Where == I propose the following date for OsmoDevCon 2018: April 20 - April 23rd, 2018 * Who: Active developers/contributors of Osmocom projects (as usual) * Where: IN-Berlin, Berlin (as usual) Please let me know ASAP if that proposed date works for everyone who'd want to attend. We can still change it now, but I would want to nail down the date pretty soon. == Format == After the experiment of reducing from 4 to 3 days last year (due to OsmoCon), we will again go for *four days* in 2018. However, we should clearly divide the days in a way that e.g. "GSM/3G" topics are on two days, while SDR+Other topics are on the other days, so people not interested in some topics can skip one or two days, as needed. We could even divide it further like: * 1 day 3GPP RAN (osmo-bts, osmo-bsc, osmo-pcu, virt_phy, fake_trx, ...) * 1 day 3GPP CN (osmo-msc, osmo-hlr, osmo-sip-connector, nextepc, etc.) * 2 days misc Regards, and looking forward to meeting you [again] in 2018, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Re: osmo-mgw[master]: MGCP endpoints: parse as decimal, not hex

by Neels Hofmeyr

I'd like to re-raise this patch I merged for discussion, it's about whether or not OsmoMGW endpoint identifiers are in hex. My patch might have gone in the wrong direction after all. https://gerrit.osmocom.org/4780 ~N On Sat, Dec 02, 2017 at 06:53:39PM +0000, Neels Hofmeyr wrote: > > Patch Set 2: > > elsewhere it seems we are confirming the hex nature of endpoint IDs (or was that a connection identifier?) ...

GAPK status update

by Vadim Yanitskiy

Dear Osmocom community, I have been working on GAPK (GSM Audio Packet Knife) for some time, and now I would like to share some achievements. Previously GAPK was represented as a single binary that could be called with some command line arguments in order to perform required operations. This is only handy for humans, but not for other programs, which may also need to perform some format / codec conversations or audio capture / playback. One of such programs is the mobile from OsmocomBB project. Currently, when you're making a voice call, both audio capture and playback are only possible on the L1 side, i.e. on a Calypso based phone. Of course, the audio stream can be redirected via MNCC socket, but this is not what a regular OsmocomBB user would like to do. Moreover, there is a lack of AMR codec support. Also, there is another GNURadio based project named GR-GSM. In short, this is a set of blocks for GSM signal reception, demodulation and further processing. At the moment, one has TCH Full Rate decoding capabilities only. Audio playback is not supported yet. Having these projects in my mind, I have got an idea of creating a shared library from the GAPK source code. And, a few days ago I was managed to get the audio playback working in OsmocomBB. I hope, this library will be also usable for other projects. Brief list of changes were made: - Composed a shared library named libosmogapk - All exposed symbols have got an 'osmo_gapk' prefix - Added a pkg-config manifest and a symbol export map - Integrated the Osmocom logging framework - Benchmarking is now disabled by default - Processing queue now based on the linuxlist - Fixed program exit due to ALSA buffer underrun - Fixed ALSA audio playback from file - Old gapk application was renamed to 'osmo-gapk' and linked against the library - Adjusted verbosity level (normal / debug) - Fixed I/O combinations (ALSA, RTP, file...) check All changes could be found at the fixeria/lib branch of GAPK. I hope to see them merged, and open for discussions ;) With best regards, Vadim Yanitskiy.

Re: Build failure of network:osmocom:nightly/osmo-msc in Debian_9.0/x86_64

by Neels Hofmeyr

These osmo-msc failures are inadvertently caused by https://gerrit.osmocom.org/4701, which is a good change once https://gerrit.osmocom.org/4980 is ready. But until then, I decided to revert it in https://gerrit.osmocom.org/5126. We shall re-apply it as soon as 4980 is merged. I wasn't expecting osmo-msc to use the new client library but needing the old bts_base config -- which I probably applied myself of course, but that detail was lost to me in the meantime. ~N On Fri, Dec 01, 2017 at 08:19:16PM +0000, OBS Notification wrote: > Visit https://build.opensuse.org/package/live_build_log/network:osmocom:nightly/o… > > Package network:osmocom:nightly/osmo-msc failed to build in Debian_9.0/x86_64 > > Check out the package for editing: > osc checkout network:osmocom:nightly osmo-msc > > Last lines of build log: > [ 136s] from msc_ifaces.c:24: > [ 136s] /usr/include/osmocom/mgcp_client/mgcp_client.h:108:14: note: declared here > [ 136s] struct msgb *mgcp_msg_dlcx(struct mgcp_client *mgcp, uint16_t rtp_endpoint, > [ 136s] ^~~~~~~~~~~~~ > [ 136s] Makefile:508: recipe for target 'msc_ifaces.o' failed > [ 136s] make[4]: *** [msc_ifaces.o] Error 1 > [ 136s] make[4]: Leaving directory '/usr/src/packages/BUILD/src/libmsc' > [ 136s] Makefile:424: recipe for target 'all-recursive' failed > [ 136s] make[3]: *** [all-recursive] Error 1 > [ 136s] make[3]: Leaving directory '/usr/src/packages/BUILD/src' > [ 136s] Makefile:460: recipe for target 'all-recursive' failed > [ 136s] make[2]: *** [all-recursive] Error 1 > [ 136s] make[2]: Leaving directory '/usr/src/packages/BUILD' > [ 136s] Makefile:392: recipe for target 'all' failed > [ 136s] make[1]: *** [all] Error 2 > [ 136s] make[1]: Leaving directory '/usr/src/packages/BUILD' > [ 136s] dh_auto_build: make -j1 returned exit code 2 > [ 136s] debian/rules:45: recipe for target 'build' failed > [ 136s] make: *** [build] Error 2 > [ 136s] dpkg-buildpackage: error: debian/rules build gave error exit status 2 > [ 136s] > [ 136s] cloud120 failed "build osmo-msc_1.1.2.20171201.dsc" at Fri Dec 1 20:19:10 UTC 2017. > [ 136s] > [ 136s] ### VM INTERACTION START ### > [ 140s] [ 111.258730] reboot: Power down > [ 141s] ### VM INTERACTION END ### > [ 141s] > [ 141s] cloud120 failed "build osmo-msc_1.1.2.20171201.dsc" at Fri Dec 1 20:19:14 UTC 2017. > [ 141s] > > -- > Configure notifications at https://build.opensuse.org/user/notifications > openSUSE Build Service (https://build.opensuse.org/) -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

LimeSDR support in osmocom:{nightly,latest} package feeds

by Harald Welte

Dear all, starting from today, we're packaging LimeSuite and (as needed) other dependencies required for using osmo-trx/osmo-bts-trx with LimeSDR in the network:osmocom:nightly and network:osmocom:latest feeds. The package versions are fixed and are not tracking "master" of e.g. limesuite. Only the Osmocom packages are tracking master. Due to the unfortunate fact that the first LimeSuite with osmo-trx support (17.09.0) requiring a cmake later than what Debian 8 ships, LimeSDR support is not working with all of the Distributions/Versions that the rest of the Osmocom stack supports. It appears that LimeSuite also has some build issues on ARM architectures, about which I've submitted an upstream bug report at https://github.com/myriadrf/LimeSuite/issues/151 But at least for x86_64 and i586 architecture, LimeSDR should be supported by the Osmocom package feeds , on Debian 9.0, Ubuntu 16.04, 16.10, 17.04 and 17.10. We will shortly use those packages as part of our osmo-gsm-tester setup at the sysmocom lab, at which point they should receive extensive testing.

Eclipse TITAN public release of SS7/SIGTRAN core protocols

by Harald Welte

Hi all, I've mentioned this many months before, but Ericsson has now (well, a month ago) finally made a public announcement about the public release of their SS7/SIGTRAN core protocols in TTCN-3. You can read more about it at https://www.eclipse.org/forums/index.php/t/1089686/ - where they actually even refer to us as being the trigger to release them. There are still many tests to write beyond those currently existing. Most recently I wrote a set of MGCP tests for our new osmo-mgw, which Philipp is now using to iron out some kinks in the codebase. The past week I've been working on simulating the minimal subset of N numbers of BSCs and N numbers of MSCs from a single test suite in order to test osmo-bsc_nat, and specifically the "IMSI-based routing to different MSCs" feature that Daniel has been working on. It's still work in progress, but definitely the by far most complex TTCN-3 project that I've written so far. After completing that, I would like to spend some more time on OsmoBTS and OsmoBSC related tests. The difficulty here is that the more we get to the RAN / air interface, the less existing prtoocols / codecs exist, so e.g. A-bis RSL would first have to be implemented. The good part is that it's actually super easy using the expressive syntax of the TITAN "raw" codec. Basically you define the structure of the data in files like http://git.osmocom.org/osmo-ttcn3-hacks/tree/library/GSM_RR_Types.ttcn and you don't have to write a single line for encoding/parsing :) Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

At least for Qualcomm LTE basebands it is true. Therefore using sub_type for differentiating encrypted and plain NAS messages were discussed there. This will likely introduce another modifications to gsmtap.h, and therefore want to discuss more about this topic also here.
