Hi Holger, Thanks for fixing this, I missed it: http://cgit.osmocom.org/cgit/libosmocore/commit/?id=952a18ed19f531b82e26108… However, this fix is incomplete: /* This generates the logging command string for VTY. */ const char *log_vty_command_string(const struct log_info *info) { int len = 0, offset = 0, ret, i, rem; int size = strlen("logging level () ()") + 1; ^^ We also have to add `(all|' there.

Problems suspected to be related to _output() rework

by Harald Welte

Hi Pablo! I am sometimes getting osmo-nitb segfaults, and sometimes random bytes as output of log messages. I've quickly started it in valgrind, and even during connection of the BTS I get the following issues: <000d> input/ipaccess.c:693 accept()ed new OML link from 192.168.200.117 ==21897== Conditional jump or move depends on uninitialised value(s) ==21897== at 0x60D4BD4: vfprintf (vfprintf.c:1620) ==21897== by 0x60F8F01: vsnprintf (vsnprintf.c:120) ==21897== by 0x4E33670: _output (logging.c:177) ==21897== by 0x4E33878: _logp (logging.c:227) ==21897== by 0x4E33BCB: logp2 (logging.c:246) ==21897== by 0x435E5C: listen_fd_cb (ipaccess.c:692) ==21897== by 0x4E32419: osmo_select_main (select.c:132) ==21897== by 0x40555B: main (bsc_hack.c:306) ==21897== ==21897== Use of uninitialised value of size 8 ==21897== at 0x60D5008: vfprintf (vfprintf.c:1620) ==21897== by 0x60F8F01: vsnprintf (vsnprintf.c:120) ==21897== by 0x4E33670: _output (logging.c:177) ==21897== by 0x4E33878: _logp (logging.c:227) ==21897== by 0x4E33BCB: logp2 (logging.c:246) ==21897== by 0x435E5C: listen_fd_cb (ipaccess.c:692) ==21897== by 0x4E32419: osmo_select_main (select.c:132) ==21897== by 0x40555B: main (bsc_hack.c:306) ==21897== ==21897== Use of uninitialised value of size 8 ==21897== at 0x6101CE0: _IO_default_xsputn (genops.c:480) ==21897== by 0x60D4ED3: vfprintf (vfprintf.c:1620) ==21897== by 0x60F8F01: vsnprintf (vsnprintf.c:120) ==21897== by 0x4E33670: _output (logging.c:177) ==21897== by 0x4E33878: _logp (logging.c:227) ==21897== by 0x4E33BCB: logp2 (logging.c:246) ==21897== by 0x435E5C: listen_fd_cb (ipaccess.c:692) ==21897== by 0x4E32419: osmo_select_main (select.c:132) ==21897== by 0x40555B: main (bsc_hack.c:306) ==21897== ==21897== Conditional jump or move depends on uninitialised value(s) ==21897== at 0x6101CF2: _IO_default_xsputn (genops.c:479) ==21897== by 0x60D4ED3: vfprintf (vfprintf.c:1620) ==21897== by 0x60F8F01: vsnprintf (vsnprintf.c:120) ==21897== by 0x4E33670: _output (logging.c:177) ==21897== by 0x4E33878: _logp (logging.c:227) ==21897== by 0x4E33BCB: logp2 (logging.c:246) ==21897== by 0x435E5C: listen_fd_cb (ipaccess.c:692) ==21897== by 0x4E32419: osmo_select_main (select.c:132) ==21897== by 0x40555B: main (bsc_hack.c:306) ==21897== <000d> input/ipaccess.c:755 accept()ed new RSL link from 192.168.200.117 <0004> bsc_init.c:251 bootstrapping RSL for BTS/TRX (0/0) on ARFCN 871 using MCC=602 MNC=42 LAC=1 CID=0 BSIC=63 TSC=7 ==21897== Use of uninitialised value of size 8 ==21897== at 0x60D2EDB: _itoa_word (_itoa.c:195) ==21897== by 0x60D5386: vfprintf (vfprintf.c:1619) ==21897== by 0x60F8F01: vsnprintf (vsnprintf.c:120) ==21897== by 0x4E33670: _output (logging.c:177) ==21897== by 0x4E33878: _logp (logging.c:227) ==21897== by 0x4E33BCB: logp2 (logging.c:246) ==21897== by 0x410141: inp_sig_cb (bsc_init.c:247) Can you please investigate?

comment on ipaccess-find: Work without providing an interface name

by Pablo Neira Ayuso

Hi Holger, I think this patch is wrong: http://cgit.osmocom.org/cgit/openbsc/commit/?id=d3080be1317cfa0269b1c12c8f2… ifname should be set if argc == 2, but it seems to be set if argc < 2, in that case argv[1] is always NULL.

Wanted: dpkg/deb/rpm package maintainer

by Harald Welte

Hi all, for quite some time we've been having debian dpkg packaging information as part of our libosmocore, libosmo-sccp, openggsn and openbsc repositories. As the library ABI sis now considered stable, it starts to make sense not only to release source tarballs, but also to offer .deb packages for ubunto and debian, probably both i386 and amd64 and lenny, squeeze and natty as well as ubuntu 10.04. The resulting packages could initially be hosted on an osmoxom.org apt feed that people can wimply put in their sources.list We're looking for somebody with dpkg packaging experience, who would volunteer to take care of building the deb files and maintaining that apt feed. If somebody wants to take care about RPM packaging, that would of course be also welcome. Thanks in advance, Harald -- Sent from a mobile device, excuse my short response

Osmocom project vs. sysmocom GmbH

by Harald Welte

Hi all! As some of you already know, Holger and I have recently started a new company called "sysmocom - systems for mobile communications GmbH". The process of establishing the new company has now formally concluded. Before some rumours start to spread, we would like to clarify some points and make sure there is mutual understanding between the Osmocom community and the sysmocom company. sysmocom is intended to provide commercial offerings related to the Osmocom projects. This is not entirely new. Especially on the network side, people like Holger and I have been doing quite a lot of paid development to bring those projects forward. We would not have many of the features we have today, if it wasn't for customers who actually pay us for development of OpenBSC, OsmoBSC, OsmoSGSN and the various side projects more targetted at a real network operator like cellmgr-ng, bsc-nat, gb_proxy - just to name a few. However, this has always only been freelancing development of Software. With sysmocom, we want to go one step further and work on hardware products related to the various Free Software projects. Right now I don't want to talk too much about unfinished products, but we are working towards an inexpensive BTS product, we are funding the prototypes for Osmocom SIMtrace, and we will likely also see stuff like OpenBSC appliances. Given our past involvement and exposure into other projects that share a split Free Software / business set-up, we think we understand very well where potential issues of conflict between the two sides may be. Let me make some more clarification what this is not about: * sysmocom is not about creating proprietary derivates of Osmocom software. We work on Free Software which is publicly available under OSI approved and FSF endorsed licenses. We may offer proprietary hardware and sometimes software - but those are independent projects from existing Osmocom software. * we specifically will not have a public and a non-public version of the same program with differences in features. * sysmocom is not a VC-funded startup. It's a very small company run out of personal funds with no intention to take external funding or grow rapidly. Nobody but Holger and I determine where it goes and what it does. * sysmocom does not hold any copyright on the Free Software projects. The copyrights stay distributed with the major authors such as Holger, Onwaves, Sylvain, Dieter, Andreas and myself. None of the others have any affiliation with sysmocom. I have (personally, unrelated to sysmocom) asked some of the smaller contributors for a copyright transfer to make sure we could do the AGPLv3 transition, or future re-licensing decisions without having to ask dozens and dozens of people. sysmocom does not seek to control the Free Software projects. * we will maintain a strict separation between the community side of things and the business side. Unlike some other popular projects, we will not end up in a situation where the osmocom.org websites will be full of advertisements and hidden links that lure you on the company website. * we will keep a strict separation of naming. Osmocom is for the FOSS projects, sysmocom for the business. The company will use the term "Osmocom" only in descriptive context, not as a product name, brand or for advertisement. If you do have any concerns, please feel free to share them. However, I'd like to avoid cross-posting them throguh different mailing lists. Please follow-up-to openbsc(a)lists.osmocom.org Regards, Harald -- - Harald Welte <hwelte(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Schivelbeiner Str. 5 * 10439 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Planning for Radio Village at 2011 CCC Camp

by Harald Welte

Hi all! [This message is cross-posted to many lists, please be careful when replying to it! Think twice if your respones really matters to all those projects...] In order to do some better planning for our Camp activities this summer, I would like to request all people who intend to participate in the radio village to add themselves to the wiki: https://events.ccc.de/camp/2011/wiki/index.php/RadioVillage The list of citizens is auto-generated if you use Person template like I have done in my user page at https://events.ccc.de/camp/2011/wiki/index.php/User:LaForge The large main tent is not really intended as a place to sleep, but more like a place where we set up our gear and work on the various projects, similar to what happened at HAR.

Questions

by Christopher HENARD

Hello everyone, 1) Is it possible to act as a nano BTS and send packets to open BSC ? But how to do that since openBSC uses config files (openbsc.cfg.nanobts, ...) ? 2)I can't get last source code with git, the command always results in a timeout: git clone git://git.osmocom.org/openbsc.git Cloning into openbsc... git.osmocom.org[0: 213.95.46.201]: errno=Connection timed out git.osmocom.org[0: 2001:780:45:f046::201]: errno=Network is unreachable fatal: unable to connect a socket (Network is unreachable) Would that be possible to update the tarballs on the wiki? It seems the current tarball of openBSC (http://openbsc.osmocom.org/trac/wiki) doesn't contains config files in the osmo-nitb directory. There's only source and makefile. The wiki mention 'OpenBSC has a configuration file. The default config file name is *openbsc.cfg* in the current working directory of the osmo-nitb process.' Thank you, Chris
