2017-08-30move libiu to osmo-iuh/libosmo-ranapNeels Hofmeyr6-30/+50
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 To be able to run the msc_vlr tests for RAN_UTRAN_IU without Iu client headers available, add iu_dummy.h, containing mere function signatures that match iu_dummy.c and a mostly empty struct ranap_ue_conn_ctx. Make sure we can build with and without --enable-iu: include osmo-iuh headers only with --enable-iu. Change-Id: Ib8c4fcdb4766c5e575618b95ce16dce51063206b
2017-08-30Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)Philipp Maier2-1/+18
This was originally a long series of commits converging to the final result seen in this patch. It does not make much sense to review the smaller steps' trial and error, we need to review this entire change as a whole. Implement AoIP in osmo-msc and osmo-bsc. Change 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. From here on, a separate osmo-stp process is required for SCCP routing between OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN jenkins.sh: build from libosmo-sccp and osmo-iuh master branches now for new M3UA SIGTRAN.

2017-08-27Treat SIGTERM just like SIGINT in our programsHarald Welte3-0/+6
When somebody kills the process, it's best to handle the signal and to use the opportunity for some cleanup. We always did this in the NITB on SIGINT, but never on SIGTERM. Let's change it. Change-Id: Iea6804325a6575ceab5edfd28dd20249462f143b

2017-08-27Migrate from gprs_apn_to_str() to libosmocore osmo_apn_to_str()Harald Welte8-51/+17
In 2015, Jacob moved/copied related functions to libosmocore, but for some reason didn't remove the copies here. Let's follow-up on that and remove duplicated code. The libosmocore commit introducing osmo_apn_to_str() was 8114294bf29ac6e44822c0ae43d4b0819f11b022 Change-Id: I7315ffcbed8a54cca2056f313bb7783ad82d0ee9
2017-08-27sgsn_vty: Don't assume pdp->lib is always validHarald Welte1-14/+16
We can only print libgtp pdp information if a library context is attached to this pdp context. This is not always the case, particuarly during some teardown scenarios. Change-Id: Ia3184877f9709db65f5f93a98403f2ef5b04a8ca
2017-08-27SGSN: Fix RAN information exposed on GTP during PDP CTX CREATEHarald Welte1-7/+18
In the PDP Context Create from SGSN to GGSN, we include information about the RAN type (GERAN/UTRAN) and the Cell of the MS. This was all hard-coded to GERAN, and wasn't updated when we added UTRAN support to the SGSN. Change-Id: I6c79e42c5e08b28fe8182555302a5505fbbaa313
2017-08-27sgsn: Convert cch_pdp to host order for libgtpHolger Hans Peter Freyther1-5/+2
libgtp is calling gtpie_tv2 which will convert this uint16_t from host to network order. So far libosmogsm and the sgsn treated the charging characteristics as opaque data. So when moving from byte array to the uint16_t do the swapping. Change-Id: I977aec2e2f8d57802e45f591754e5733562d5c2a
2017-08-27gtphob: check for missing result of rate_ctr_group_alloc()Harald Welte1-0/+4
In case the counter group allocation fails, we must handle this gracefully and fail the allocation of the parent object, too. The recent change (Id I7dad4a4d52fe05f6b990359841b4408df5990e21) seems to have missed one instance, so let's follow-up. Change-Id: I1ee9e3d26dcc18e7f979fd9a786162cbcc50942c Related: OS#2361

2017-08-27sgsn: Fill the cch_pdp with a value coming from the tlv structureHolger Hans Peter Freyther3-5/+37
For some GGSNs we need to insert the PDP Charging Characteristics that were returned. We receive these values from GSUP and will fill them into the tlv structure when finding the ggsn context. Change-Id: I1725bfd2403d29ce3550bfcd6fcc1498426ef906
2017-08-27Implement IuCS (large refactoring and addition)Neels Hofmeyr5-12/+24
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 Enable MSC specific CTRL commands, bsc_base_ctrl_cmds_install() still needs to be split up.

2017-08-27sgsn 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

2017-08-27Use 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
2017-08-27gsup_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.

2017-08-27GPRS/IuPS: remove all 3G authentication dev hacksNeels Hofmeyr1-27/+0

2017-08-27move 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
