2017-08-11move libiu to osmo-iuh/libosmo-ranapNeels Hofmeyr23-1027/+121
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.

2017-08-11Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)Philipp Maier36-649/+3398
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 Patch-by: pmaier, nhofmeyr, laforge Change-Id: I5ae4e05ee7c57cad341ea5e86af37c1f6b0ffa77
2017-08-1104.08: log protocol discriminators and message types by nameNeels Hofmeyr1-6/+8
On incoming 04.08 messages, we log only the protocol discriminator in decimal. Enhance: log pdisc and message type in hex, and also log the protocol and message type as human readable string. Also adjust the msc_vlr tests' log statements for wrapped rx/tx functions of dtap from/to the MS. Adjust the expected output of msc_vlr_tests.

2017-08-11mgcp: hack RAB success from nano3G: patch first RTP payloadNeels Hofmeyr1-0/+7
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.

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
2017-08-11mscsplit: various preparations to separate MSC from BSCNeels Hofmeyr21-983/+335
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.

2017-08-11osmo-nitb: change default db name to sms.dbNeels Hofmeyr1-1/+1
libvlr now delegates subscriber management to osmo-hlr, so the database no longer represents a HLR. It basically only stores SMS, so reflect that fact in the default database name. Change-Id: I3289d68d3eb63aff940b48a25b584d5e83cd0197
2017-08-11Use libvlr in libmsc (large refactoring)Harald Welte35-3198/+1633
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

2017-08-11gsup_client: allow passing a unit id to identify with HLRNeels Hofmeyr3-5/+16
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.

2009-06-09some more commentsHarald Welte1-2/+3
2009-06-09db.c: tmsi may be empty so put it into '' to make that obvoius (Andreas ↵Holger Freyther1-3/+3
Eversberg) during attachment, the "tmsi" field of the subscriber may be an empty string, so the string must be quoted in the sql request, or the sql request fails due to incorrect syntax. also i added "extension" field to debug output.
2009-06-09gsm_04_08.c: Kill duplication pointed out by Andreas EversbergHolger Freyther1-22/+18
Introduce the internal gsm0408_authorize that will determine if we allow the user into our network. If allowed a new tmsi will be allocated, the subscr_update will be called, the loc_operation released, and the accept sent. Otherwise just return 0. The code was copied from mm_rx_id_resp.
2009-06-09gsm_04_08.c: Call subscr_update everytime we let someone in (Andreas Eversberg)Holger Freyther1-0/+1
If location update is requested, but subscriber is not yet authorised within mm_rx_loc_upd_req() function, the subscr_update() is not called, because subscriber information is not complete. During mm_rx_id_resp() the subscriber informations is may be complete, so authorize subscriber succeeds and database must be updated.
2009-06-09bsc_hack.c: Fix the -l db option (Andreas Eversberg)Holger Freyther1-1/+1
Add ':' to indicate an argument will follow -l.
2009-06-08Add the isdnsync program which enable layer1 and layer2 on a cardHolger Freyther2-1/+195
this small tool is used to enable layer 1 and 2 on a given isdn card. the card can be used to retrieve clock signal from a network. layer 2 (PTP) is required to keep layer 1 without interruption. this tool works on e1 and s0 cards. to use the clock signal with other cards, interconnection with a clock-slave-card is required. (Andreas Eversberg)
2009-06-06gsm_04_08.c: Some spoofing protection against two location updating requestsHolger Freyther1-0/+11
Do not allow two location updating requests on the same lchan. Such an event is certainly spoofed and can confuse the internal logic of the application. Prevent that.
2009-06-06lchan: Handle the abnormal case of channel getting closedHolger Freyther2-1/+28
The abnormal case is that lchan_free ist getting called due a RSL_MT_CHAN_REL_ACK in the RSL but the refcount of this channel is not zero. This means that some "logical operation" is still going on that needs to be cancelled. Instead of always queuing up all operations in the struct gsm_lchan use the signal framework to inform higher layers about this abnormal case. In gsm_04_08.c a signal handler is installed and in the abnormal case the location updating request operation is freed.
2009-06-06Revert "[db] Keep track of the current gsm_network"Holger Freyther2-4/+2
This was a stupid decision. We will have to assign the network at some other place. The problem will be a problem when we have two gsm_networks in one process and the same subscriber is traveling in both networks.

2009-06-04[subscr] Remove the struct gsm_bts pointer from subscriberHolger Freyther1-6/+2
The pointer was initially added to support to open a lchan by using the gsm_subscriber structure. We would have restored the struct gsm_bts from the db when loading the subscriber. Instead we will dynamically resolve the gsm_bts and might end up paging multiple bts in the same (stored/old) location area until it answers.
2009-06-04[debug] Move subscr_get_by_tmsi below the debug statement (Andreas Eversberg)Holger Freyther1-1/+2
subscr_get_by_tmsi might log as well and then the order of debugging it not as clear as it could be.
2009-06-02[misc] Search for the crypt symbol to conditionally enable crypt in VTYHolger Freyther1-2/+2
It will define -DVTY_CRYPT_PW= if crypt is found. If -lcrypt is needed, $(LIB_CRYPT) will be -lcrypt. Compiles on OS X and Linux and reenables crypt. Patch by: Lars Immisch
2009-06-02[l2] Do not always release the layer2 when closing the socket (Andreas ↵Holger Freyther1-3/+2
Eversberg) Tells mISDN not to release layer 2 on closing socket, when not requested. If mISDN was told to release layer 2 once, it will continue to release layer 2 on every shutdown of OpenBSC.
2009-06-02[e1] Correctly initialize the e1link (Andreas Eversberg)Holger Freyther1-8/+24
During bootstrap of BS11, the e1links are initialized. This must also be done when BS11 is already bootstrapped (when restarting OpenBSC). It is required to correctly multiplex the audio traffic between channels. Without it, all time slots refer to card 0, slot 0, subslot 0, which causes crashes when handling TRAU frames..
2009-06-02[debug] Change DEBUGPC statements to contain \n (Andreas Eversberg)Holger Freyther2-12/+14
Some debug outputs now correctly use end-of-line characters.
