2017-07-25split off osmo-msc: remove files, apply build, renameNeels Hofmeyr39-25031/+0
Change-Id: Icf025e5ea8d180613b3114282951c9afa67af9a7
2017-07-25move libiu to osmo-iuh/libosmo-ranapNeels Hofmeyr6-28/+28
Remove libiu here, use the functions from libosmo-ranap instead, by applying the ranap_ / RANAP_ prefix. Corresponding change-id in osmo-iuh.git is I6a3f7ad15be03fb94689b4af6ccfa828c25f45c0 Change-Id: Ib8c4fcdb4766c5e575618b95ce16dce51063206b
2017-07-25common-vty: add ss7 nodes commands to VTYPhilipp Maier1-0/+2
The current VTY implementation has no knowledge about the libosmo-sccp nodes and therefor can not resolve parent nodes, nor decide if we deal with a config node. Change-Id: I815a57ed6270bd55c25ee9a8f45026d4aaad9004
2017-07-25AoIP+3G: use one common SCCP client for A and IuCSNeels Hofmeyr1-1/+15
Move osmo_sccp_simple_client() setup out of iu_init() and a_init(). In msc_main.c and sgsn_main.c, initialize the STP connection first and then pass to iu_init() and a_init(). This allows serving 3G (IuCS) and 2G (A) from one and the same MSC instance. Since both OsmoHNBGW and OsmoBSC are using PC 23 by default now, move BSC to PC 42 (because OsmoBSC typically has vty port 4242, bla). Also: a_iface.c: remove now unused defines a_init(): remove osmo_ss7_init() call that duplicated msc_main.c Change-Id: I963a94e1a0bfc455992d22940dcc9c67c44570b9
2017-07-25sgsn: add missing osmo_ss7_init()Neels Hofmeyr1-0/+1

2017-07-25WIP: Port to new libosmo-sigtran API (with proper M3UA for Iuh)Harald Welte1-1/+1
This changes over to the new libosmo-sigtran API with support for proper SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and IuPS interfaces. Only the ASP (client) is used, assuming that both the HNB-GWs and RNCs as well as the MSCs and SGSNs are all connecting as ASP to some STP/SGW which offers M3UA server functionality as well as point-code and/or global title based routing.

2017-07-25Implement IuCS (large refactoring and addition)Neels Hofmeyr5-12/+22
osmo-nitb becomes osmo-msc add DIUCS debug log constant add iucs.[hc] add msc vty, remove nitb vty add libiudummy, to avoid linking Iu deps in tests Use new msc_tx_dtap() instead of gsm0808_submit_dtap() libmgcp: add mgcpgw client API bridge calls via mgcpgw mgcp: hack RAB success from nano3G: patch first RTP payload The ip.access nano3G needs the first RTP payload's first two bytes to read hex 'e400', or it will reject the RAB assignment. Add flag patched_first_rtp_payload to mgcp_rtp_state to detect the first RTP payload on a stream, and overwrite its first bytes with e400. This should probably be configurable, but seems to not harm other femto cells (as long as we patch only the first RTP payload in each stream). Only do this when sending to the BTS side.

2017-07-25sgsn init: pass sgsn_config pointer to sgsn_vty_init(), not sgsn_parse_configNeels Hofmeyr2-5/+8
In an upcoming commit, sgsn_vty_init() will require access to the global sgsn config struct to initialize a generic VTY command with the proper config destination address, see Change-Id I5b5b6a9678b458affa86800afb1ec726e66eed88. Change-Id: Ie6b6e5422987586531a898e0c5b867623dbecb0f

2017-07-23Use libvlr in libmsc (large refactoring)Harald Welte1-0/+3
Original libvlr code is by Harald Welte <laforge@gnumonks.org>, polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>. This is a long series of trial-and-error development collapsed in one patch. This may be split in smaller commits if reviewers prefer that. If we can keep it as one, we have saved ourselves the additional separation work. SMS: The SQL based lookup of SMS for attached subscribers no longer works since the SQL database no longer has the subscriber data. Replace with a round-robin on the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the subscriber is currently attached. If there are many SMS for not-attached subscribers in the SMS database, this will become inefficient: a DB hit returns a pending SMS, the RAM lookup will reveal that the subscriber is not attached, after which the DB is hit for the next SMS. It would become more efficient e.g. by having an MSISDN based hash list for the VLR subscribers and by marking non-attached SMS recipients in the SMS database so that they can be excluded with the SQL query already. There is a sanity limit to do at most 100 db hits per attempt to find a pending SMS. So if there are more than 100 stored SMS waiting for their recipients to actually attach to the MSC, it may take more than one SMS queue trigger to deliver SMS for subscribers that are actually attached. This is not very beautiful, but is merely intended to carry us over to a time when we have a proper separate SMSC entity. Introduce gsm_subscriber_connection ref-counting in libmsc. Remove/Disable VTY and CTRL commands to create subscribers, which is now a task of the OsmoHLR. Adjust the python tests accordingly. Remove VTY cmd subscriber-keep-in-ram. Use OSMO_GSUP_PORT = 4222 instead of 2222. See I4222e21686c823985be8ff1f16b1182be8ad6175. So far use the LAC from conn->bts, will be replaced by conn->lac in Id3705236350d5f69e447046b0a764bbabc3d493c. Related: OS#1592 OS#1974 Change-Id: I639544a6cdda77a3aafc4e3446a55393f60e4050
2017-07-13gsup_client: allow passing a unit id to identify with HLRNeels Hofmeyr1-0/+1
Before, each GSUP client would contact the HLR with an identical unit id, i.e. "SGSN-00-00-00-00-00-00", with the result that some messages were sucked off by the wrong client. Pass explicit unit name from each gsup client user, so that OsmoMSC is "MSC" and OsmoSGSN is "SGSN". Hence the HLR can properly route the messages. Todo: also set some values instead of the zeros. Unrelated cosmetic change while editing the arguments: gsup_client_create()'s definition's oap client config arg name mismatched the one used in the declaration. Use oapc_config in both.

2017-07-13GPRS/IuPS: remove all 3G authentication dev hacksNeels Hofmeyr1-27/+0

2017-07-12move openbsc/* to repos rootNeels Hofmeyr39-0/+25004
This is the first step in creating this repository from the legacy openbsc.git. Like all other Osmocom repositories, keep the autoconf and automake files in the repository root. openbsc.git has been the sole exception, which ends now. Change-Id: I9c6f2a448d9cb1cc088cf1cf6918b69d7e69b4e7
