Hi all, I was very liberal in just using numbers from the 'open' number range. We should move to a different scheme and just take the liberty to take one ID and then have our own header inside there. I would propose to do something like this struct ipa_proto_hdr { uint16_t len; uint8_t proto; data[0]; } packed; struct osmo_ipa_proto_hdr { uint8_t osmo_proto; data[0]; } packed;. Any comments?

Connecting to real MSC...

by Omar Atia

Dear All, Can you advise how I could make connections to real MSCs from Openbsc ? Is it supported by OpenBSC? I believe it is over A protocol right ? SCCP ? Thanks, Omar Atia

RFC: Relicensing OpenBSC under AGPLv3

by Harald Welte

Hi all! This subject came to my attention again recently: Why not relicense OpenBSC under AGPLv3? Right now we are licensing under GPLv2+ (v2 or any later version). However, if an operator was to make lots of private modifications and then operate it on his own network, there would be no distribution and thus no need for him to release his modified versions of the source code. This may sound a bit strange to those who have been with the project since its early days. But we are reaching production quality now, and we already have the first number of production deployments of the software. Companies like Netzing and On-waves have been FOSS-friendly and funding parts of our development effort. They have no issues with the result being Free Software again. However, there are definitely other companies out there who are less fond of sharing... So thus my idea is to put OpenBSC under AGPLv3. This way whoever uses OpenBSC _in modified form_ to operate a communications network will have to provide the source code to that modified form on a network server at no charge. The only controversial question to me is "your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source". 1) does a gsm network count as computer network? i'd say yes. 2) is using a gsm network 'interacting with it remotely'? I'd also say yes 3) what does 'prominently offer' mean in the context of GSM? We don't want the operator to spam their users with advertisement SMS just to know that they can get the soruce code, after all. Notwithstanding those open questions, such a network operator would always have the option of simply sending back his changes for integration in the official project - and thus he would no longer use a modified version which then means there is no need for the prominent notice / download at all. We can make this very clear in the project documentation, putting further encouragement The actual relicensing should be less problematic than I thought, since AGPLv3 is compatible with GPLv3. So I could re-license all parts that I own copyright on (which should be the majority of the code base anyway) under AGPLv3, while the former GPLv2+ components (like VTY code from zebra, or contributions by other people) then become GPLv3-or-later. Of course I would want to encourage all developers/contributors to also follow the re-licensing. Particularly Holger Freyther, Dieter Spaar, Andreas Eversberg, Jan Luebbe, Sylvain Munaut, Daniel Willmann, Stefan Schmidt. So let's start with a poll: a) Do you think re-licensing to AGPLv3 is a good idea? b) If you have contributed, would you re-license your code under AGPLv3? If we have some kind of concesus in the community, I would approach On-waves whether they would want to do the same for their share of the copyright. As their "modifications" are all part of OpenBSC git repository, they would not be subject to any different conditions than before. Thanks in advance for your feedback, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Just in case, Cygwin also misses cfmakeraw(), my private modification for this is the following which is of course the same you quoted from the man page. #if defined(__CYGWIN__) /* Workaround for Cygwin, which is missing cfmakeraw */ /* Pasted from man page */ void cfmakeraw(struct termios *termios_p) { termios_p->c_iflag &= ~(IGNBRK|BRKINT|PARMRK|ISTRIP|INLCR|IGNCR|ICRNL|IXON); termios_p->c_oflag &= ~OPOST; termios_p->c_lflag &= ~(ECHO|ECHONL|ICANON|ISIG|IEXTEN); termios_p->c_cflag &= ~(CSIZE|PARENB); termios_p->c_cflag |= CS8; } #endif /* defined(__CYGWIN__) */ Maybe there is a Solaris-specific preprocessor symbol and we can add this function to an appropriate place.

Notes from the 27C3 network

by Holger Hans Peter Freyther

Hi all, here are some notes about bsc_hack as it ran on the 27C3. In day0 we discovered a nice SQL injection bug, in day1 we had plenty of segfaults, mostly in the error and time-out paths of the MSC (but also some in the BSC API). These included crashes due clearing the channel and removing the ->lchan from the conn, RLL time out handling in the SMS code and some more. The network ran without segfault (only one crash due my stupidity on a new VTY command) after this. The biggest issue as that SMS got stuck. Code review has found some issues immediately but this didn't fix it. On more code review an issue with the 'subscr_get_channel' was identified. First of all the transaction layer just stopped paging requests, e.g. stopping the paging for someone else's subscr_get_channel, then the Call Control code never called subscr_put_channel when it is done. I have created two band aids for this situation but there is a bigger issue with the code. If somebody has spare time and wants to do some simple changes one can do: 1.) The subscriber layer passes the 'subscr' pointer to the paging layer, it should pass the request to it. 2.) It should be possible to cancel channel requests that were not scheduled yet. 3.) Once we started auth on the channel the 'request' state should be changed too. It is not right now due 1.). 4.) ....

Dear All, I will introduce myself , It is Omar Atia from Lebanon , 8 years telecom experience , willing to know more about open BSC , how can I get the sources if it is free download them (not through unix), from where could I buy the BTS stations are they available it has been sold out as written on the web site . can we configure OpenBTS with OpenBSC ? is it configurable or not tested yet . I have a lot of questions related to this Area as I want to implement the GSM network for testing purposes only to go deeply into it .
