2018-07-30remove libcommonHarald Welte9-2446/+0
This seems to b remaining from ancient days. The code in there is either no longer needed, or has been moved to libosmocore. Change-Id: I9307f9da7f48dd0a2e1cb213072068736e569722

libosmogsm in libosmocore.git from Change-Id Ie36729996abd30b84d1c30a09f62ebc6a9794950 onwards contains oap_client.c, so we don't need our local copy here in this repo anymore.

2018-04-16use osmo_init_logging2(), fix regression test memleaksNeels Hofmeyr1-2/+3
Particularly gbproxy_test.c had various mem leaks, which (will) show up with gcc (Debian 7.3.0-15) 7.3.0 address sanitizer. Fix those leaks to verify that we don't have memleaks in the production code. Change-Id: Ia4204c8b3d895b42c103edecb61b99d3d22bd36f
2018-01-19Use gsm48_encode_ra() for RAI encodingMax1-9/+0
It has stricter type signature which increase the chance of spotting misuse either via compiler warning or with automated scan. This also paves the way for gsm48_construct_ra() deprecation in libosmocore. Change-Id: I2c0f082dc7214ed57a40dad0788e34b838dfac97 Related: OS#1640

2017-08-30Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)Philipp Maier2-6/+20
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.

2017-08-27Fix gsm_pchan2chan_nr() to use RSL_CHAN_OSMO_PDCHHarald Welte1-1/+4
When converting from GSM_PCHAN_PDCH, we should generate a RSL channel number IE with the osmocom extension RSL_CHAN_OSMO_PDCH rather than claiming it is a regular TCH/F channel. This is important as this function is used by osmo-bts, too - and it decides which channel number IE is put in the GSMTAP header for both GSMTAP tracing as well as the GSMTAP based osmo-bts-virtual. In order to avoid any unintended effect on libbsc, we make sure to modify rsl_ipacc_pdch_activate() to always use GSM_PCHAN_TCH_F in related RSL message.

2017-08-27libcommon: Fix log output for bts>0.Alexander Chemeris2-3/+5
Fixes regression probably introduced in c696cc28. For bts>0 logging doesn't show bts number correctly when printing lchan identification string - it will always show it as "bts=0". The reason for this is that the identification string is cached before bts->nr value is set to a proper value. This patch sets bts->nr as part of the first step of the bts structure initialization, before caching happens thus making sure the cached identification string is cached with the correct values.

2017-08-27mscsplit: various preparations to separate MSC from BSCNeels Hofmeyr2-34/+1
Disable large parts of the code that depend on BSC presence. The code sections disabled by #if BEFORE_MSCSPLIT shall be modified or dropped in the course of adding the A-interface. Don't set msg->lchan nor msg->dst. Don't use lchan in libmsc. Decouple lac from bts. Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication: Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to different interfaces depending on the actual subscriber connection. While iu_tx() is going to be functional fairly soon, the a_tx() is going to be just a dummy for some time (see comment). Add Iu specific fields in gsm_subscriber_connection: the UE connection pointer and an indicator for the Integrity Protection status on Iu (to be fully implemented in later commits). Add lac member to gsm_subscriber_connection, to allow decoupling from bts->location_area_code. The conn->lac will actually be set in iu.c in an upcoming commit ("add iucs.[hc]"). move to libcommon-cs: gsm48_extract_mi(), gsm48_paging_extract_mi(). libmsc: duplicate gsm0808 / gsm48 functions (towards BSC). In osmo-nitb, libmsc would directly call the functions on the BSC level, not always via the bsc_api. When separating libmsc from libbsc, some functions are missing from the linkage. Hence duplicate these functions to libmsc, add an msc_ prefix for clarity, also add a _tx to gsm0808_cipher_mode(): * add msc_gsm0808_tx_cipher_mode() (dummy/stub) * add msc_gsm48_tx_mm_serv_ack() * add msc_gsm48_tx_mm_serv_rej() Call these from libmsc instead of * gsm0808_cipher_mode() * gsm48_tx_mm_serv_ack() * gsm48_tx_mm_serv_rej() Also add a comment related to msc_gsm0808_tx_cipher_mode() in two places. Remove internal RTP streaming code; OsmoNITB supported that, but for OsmoMSC, this will be done with an external MGCP gateway. Remove LCHAN_MODIFY from internal MNCC state machine. Temporarily disable all paging to be able to link libmsc without libbsc. Skip the paging part of channel_test because the paging is now disabled. Employ fake paging shims in order for msc_vlr_tests to still work. msc_compl_l3(): publish in .h, tweak return value. Use new libmsc enum values for return val, to avoid dependency on libbsc headers. Make callable from other scopes: publish in osmo_msc.h and remove 'static' in osmo_msc.c add gsm_encr to subscr_conn move subscr_request to gsm_subscriber.h subscr_request_channel() -> subscr_request_conn() move to libmsc: osmo_stats_vty_add_cmds() gsm_04_08: remove apply_codec_restrictions() gsm0408_test: use NULL for root ctx move to libbsc: gsm_bts_neighbor() move to libbsc: lchan_next_meas_rep() move vty config for t3212 to network level (periodic lu) remove unneccessary linking from some tests remove handle_abisip_signal() abis_rsl.c: don't use libvlr from libbsc gsm_subscriber_connection: put the LAC here, so that it is available without accessing conn->bts. In bsc_api.c, place this lac in conn for the sake of transition: Iu and A will use this new field to pass the LAC around, but in a completely separate OsmoBSC this is not actually needed. It can be removed again from osmo-bsc.git when the time has come. Siemens MRPCI: completely drop sending the MRPCI messages for now, they shall be added in osmo-bsc once the A-Interface code has settled. See OS#2389.

2017-08-27Use libvlr in libmsc (large refactoring)Harald Welte5-144/+40
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 Hofmeyr2-5/+15
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.
