Hi all, I would like to post the sysmocom/iups branch for review in gerrit, but I'm not sure that we want those 40 commits to be posted to all mail inboxes and sit there, ungrouped in the list of commits in gerrit. gerrit shows 'related' patches, but it doesn't have the concept of a patch-set per se. The list of pending patches will be very long, IIUC sorted with the last branch commit on top and earlier ones further down. I'd like to push it to for/master now, but first giving you guys a chance to suggest another way for this special batch. ~Neels -- - 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: Holger Freyther, Harald Welte

[PATCH 1/1] fix typos in all manuals

by Jonathan Brielmaier

Hello, I fixed typos in the osmo-gsm-manuals repository. This is my first contribution to the Osmocom project so I'm not quite sure if I did all the things (patch, email) in the right way.

Hi, It might interest you that OpenBSC has entered Debian unstable today! https://tracker.debian.org/news/755641 Please test the package and file bugs as you find them. I haven't added init/service files yet to the package, since it needs some careful thought around what default is the best for the general users. Best regards, Ruben

Splitting out M3UA and MTP3 out of Open BSC into a separate library

by Arran Cudbard-Bell

Hi, Developing a module for FreeRADIUS to support EAP-SIM and EAP-AKA authentication against a HLR. The HLR we were targeting only supported a SCTP/M3UA/SCCP/TCAP/MAP stack, so we couldn't use SUA. Ripping the M3UA/MTP3 code out of OpenBSC worked surprisingly well. We ended up running the event loop in a separate thread to work around the threading issues. Unfortunately the HLR implements the ANSI variant of everything, whereas OpenBSC and supporting libraries seem to have been written to be compatible with the ITU standards. ...but the differences are fairly minor at MTP3 and SCCP layers, and i've started work on a patchset for libosmo-sccp. https://gerrit.osmocom.org/#/c/73/ Anyway, trying to gauge interest in splitting those layers out of Open BSC into a separate library, would be happy to take on M2UA as well for consistency. It would almost certainly get more projects using the code. There's very little out there even in Perl land for working with SS7. Thanks, -Arran Arran Cudbard-Bell <a.cudbardb(a)freeradius.org> FreeRADIUS Development Team FD31 3077 42EC 7FCD 32FE 5EE2 56CF 27F9 30A8 CAA2

If it's locked, it may try to send some message to the network to verify that it's connected to an allowed operator. A useful log would be a pcap trace of communication between OpenBSC and OsmoBTS (make sure osmo-trx communication is filtered out). -- Regards, Alexander Chemeris CEO Fairwaves, Inc. https://fairwaves.co

[PATCH] libosmo-netif[releases/0.0.6-stable]: osmux: Add function to delete all msgs pending for a circuit

by Holger Freyther

Hello Jenkins Builder, I'd like you to do a code review. Please visit https://gerrit.osmocom.org/122 to review the following change. osmux: Add function to delete all msgs pending for a circuit Use this function in osmux_batch_del_circuit() since msgs are stored in a list per circuit. After the circuit is free()d the msgs are lost. Before this patch any messages enqueued inside a batch when the circiut is deleted were leaking.
