Hi, according to a lot of sources one would think, that EC20 is based around the Qualcomm MDM9615, but the picture of naked EC20[1] clearly shows, that there is Qualcomm MDM9215 chip soldered on the board. Which source is true? :-) Or it's just a wrong text on that BGA? 1. https://osmocom.org/attachments/download/2501/ec20-naked-top.jpg -- ynezz

Relicensing optimized Viterbi decoder

by Vadim Yanitskiy

Hi Tom, Recently I already asked for your permission to relicense the GSM 05.03 code from OpenBTS, and now I am contacting you with the same purpose. I am going to move your optimized Viterbi decoder forward, but currently it is licensed under the LGPL v2.1 (or later). To avoid license mix within the core Osmocom library, it would be better to relicense your code to the same one, if you agree. So, the question is: do you agree to relicense your code under the GPLv2-or-later? With best regards, Vadim Yanitskiy.

RFC: OsmoDevCon 2017 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.] >From 2012 to 2016 we were running a series of small, invitation-only Osmocom Developer Conferences. Access was intentionally restricted to those community members who have demonstrated an existing track record of contribution to any of the projects under the Osmocom umbrella. This format of a small, tightly knit group of about 20 people has been successful over the years, and I have received a lot of positive feedback from past participants. On the other hand, the Osmocom project has grown in scope and diversity, and some of those projects don't have all that much relationship to each other - except being started by people from within the same group. There's the cellular communications (GSM/GPRS/EDGE/UMTS and hopefully at some point LTE) protocols which is attracting a lot of professional users. And then there's pure community projects like rtl-sdr, OsmocomBB, OsmocomGMR and many other efforts. Particularly the cellular infrastructure projects (OsmoBTS, OsmoPCU, OsmoBTS, OsmoNITB, OsmoSGSN, OpenGGSN, OsmoIuh & co) are somehow "standing out" of the othe projects in the context of having a wider user bsae, and in that user base also primarily commercial users. So I'd like to start a discussion on how to possibly change the event format to accomodate the various interests and parties. I definitely don't want to loose the "annual meeting of old friends" atmosphere, while at the same time also opening up to other interested parties. One idea would be to keep OsmoDevCon as-is and have a separate event where non-contributing/developing users / sysadmins / system integrators could also be attending. Another idea would be to split into a 'user day' and 'developer days' format. This is something the netfilter developer workshops have been using for many years, and from my limited insight quite successfully so. The "user day" is more like a traditional tech conference, with a large auditorium and talks oriented towards users / sysadmins / integrators of the software. The "developer days" are the invitation-only part, for known contributing developers only, similar to what we have at OsmoDevCon. Having both events (or both parts of an event) back-to-back has the advantage that a large number of potential speakers for the 'user day' are already present, and they don't have to travel yet another time. One could even structure it further and say we have one user day, one public 'Osmocom cellular developer day' and then the closed 'OsmoDevCon classic', maybe reduced from 4 days to 3 or even 2 days only? What is the general opinion about this? Are there people lurking on this list who would be interested in attending a public 'user day' or even 'developer day' about the Osmocom cellular projects, with presentations and workshops around topics such as running Osmocom based cellular networks? In terms of when/where, I would suggest to keep the tradition of April in Berlin/Germany. But I'm of course very happy if somebody wants to host it some place else... Regards, and looking forward to meeting you [again] in 2017, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Contribute to Osmocom and receive a free 3.5G femtocell

by Harald Welte

Dear all, not everyone might have seen the news item that was posted in late December on our website at http://osmocom.org/news/62 I'm looking forward to receiving your proposal on how you would contribute to the Osmocom project if you were to receive one of those free 3.5G femtocells. Quote of the news item below: ------ So please excuse me to cross-post this over several Osmocom project mailing lists. I know that a number of people have either hacked on femtocells in the past, or at least expressed interest in doing so... Osmocom's support for 2G/GSM is mature and widespread. Since 2016, we're taking on the next level: 3G/3.5G. The key to running your own 3G network is to obtain actual 3G cell hardware -- here is an exciting opportunity to get started: No less than 50 femtocells will be given away for free by sysmocom, one of the main drivers of the Osmocom project. To receive a free 3G femtocell, tell us how you will help the Osmocom project drive 3.5G forward if you had one, before the end of January 2017. This marks the launch of the 3.5G Acceleration Project, backed by the Osmocom community. Join us! Find further details on the 3.5G Acceleration Project and receiving your own 3G femtocell for free at https://sysmocom.de/downloads/accelerate_3g5_cfp.pdf. ------ Best regards and happy hacking, Harald Welte -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

A quick online search didn't seem like anyone else has yet come up with a solution for this, so I guess we should turn it off. I remember some discussion on the list about a year ago where the concensus was to disable LeakSanitizer by environment variables on the buildhost anyway? -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

log messages summary

by Neels Hofmeyr

Hi Max, you recently tend to have very general commit log summaries. The summary should best contain a hint at the general area the patch is about, so a reader can quickly know whether a patch could be related to a given other topic. I've asked so on gerrit a few times, and now also found a couple of commits merged IMHO with ETOOGENERAL, so I thought I'd drop a note: osmo-bts: 2017-01-06 17:30 Max o Log socket path on error 2017-01-02 18:17 Max o Move code to libosmocore 2016-11-11 17:44 Max o Remove duplicated code osmo-pcu: 2017-01-06 17:20 Max o Log socket path on connection 2017-01-05 18:26 Max o Improve logging Would be nice to add an indicator to the summary in the future. A small word or phrase in the beginning is enough, like 'rsl: frobnicate', or include a function name or -prefix for code dup / moved code.
