2020-02-10add full SDP codec information to the MNCC socketNeels Hofmeyr27-443/+5489
This way osmo-msc can benefit from the complete codec information received via SIP, which was so far terminated at osmo-sip-connector. osmo-sip-connector could/should have translated the received SDP to MNCC bearer_cap, but this was never implemented properly. Since osmo-msc already handles SDP towards the MGW, it makes most sense to pass SDP to osmo-msc transparently. To be able to send a valid RTP IP:port in the SDP upon the first MNCC_SETUP_IND going out, move the CN side CRCX to the very start of establishing a voice call. As a result, first create MGW conns for both RAN and CN before starting. The voice_call_full.msc chart shows the change in message sequence for MO and MT voice calls. Implement cc_sdp.c, which accumulates codec information from various sources (MS, BSS, Assignment, remote call leg) and provides filtering to get the available set of codecs at any point in time. Implement codec_sdp_cc_t9n.c, to translate between SDP and the various libosmo-mgcp-client, CC and BSSMAP representations of codecs: - Speech Version, - Permitted Speech, - Speech Codec Type, - default Payload Type numbers, - enum mgcp_codecs, - FR/HR compatibility - SDP audio codec names, - various AMR configurations. A codec_map lists these relations in one large data record. Various functions provide conversions by traversing this map. Add trans->cc.mnccc_release_sent: so far, avoiding to send an MNCC release during trans_free() was done by setting the callref = 0. But that also skips CC Release. On codec mismatch, we send a specific MNCC error code but still want a normal CC Release: hence send the MNCC message, set mnccc_release_sent = true and do normal CC Release in trans_free(). (A better way to do this would be to adopt the mncc_call FSM from inter-MSC handover also for local voice calls, but that is out of scope for now. I want to try that soon, as time permits.)

2020-01-27msc/sccp_ran.h: fix: do not pass -1 to osmo_rat_type_name()Vadim Yanitskiy1-2/+2
The problem is that osmo_rat_type_name() calls get_value_string(), so we first cast -1 to 'const enum osmo_rat_type' and then to 'uint32_t'. Let's rather use OSMO_RAT_UNKNOWN.

2020-01-25libmsc: move subscriber expiration timer T3212 to libvlrVadim Yanitskiy8-69/+54
Since the split of OsmoNiTB, OsmoMSC does not deal with the radio access network directly. Therefore the only purpose of T3212 is to control subscriber expiration in the local VLR. The timeout value indicated in System Information Type 3 needs to be configured separately in the BSC/RNC. This means that we don't need to store it in deci-hours anymore. Let's move T3212 to the group of VLR specific timers, so it can be configured and introspected using the generic 'timer' command, and deprecate the old '[no] periodic location update' command. It should be also noted that in the old code subscriber expiration timeout was actually set to twice the T3212 value plus one minute. After this change, we apply the configured value 'as-is', but keep the old behaviour for 'periodic location update' command. Change-Id: I9b12066599a7c834a53a93acf5902d91273bc74f
2020-01-25libvlr: use generic osmo_tdef API for T3250, T3260, and T3270Vadim Yanitskiy6-28/+22
These timers so far were implemented as a list of unsigned integers, which has never been initialized to any reasonable defaults. Since they are used as state timeouts in several FSMs, we might end up staying in some state forever. Let's migrate to generic osmo_tdef API and use default values from table 11.2 of 3GPP TS 24.008. This way the user can introspect and change their values from the VTY / configuration file. Change-Id: Ia8cf98da0aea0e626c5ff088a833d7359c43847f Related: OS#4368
2020-01-25VTY: add osmo_tdef introspection and configuration commandsVadim Yanitskiy5-0/+67
This change introduces several new VTY commands letting the user a possibility to introspect and reconfigure some of the existing timers implemented using libosmocore's osmo_tdef API. At the moment this covers the following timers: - MGW specific timers: - X1 - MGCP response timeout, - X2 - RTP stream establishing timeout, - RAN specific timers (same names for GERAN and UTRAN): - X1 - Authentication and Ciphering timeout, - X2 - RAN connection release sanity timeout, - X3 - Handover procedure timeout. The following commands are introduced: - 'enable' node: - show timer [(mgw|mncc|sccp|geran|utran|sgs)] [TNNNN] - 'config-msc' node: - timer [(mgw|mncc|sccp|geran|utran|sgs)] [TNNNN] [(<0-2147483647>|default)] Both MNCC and SCCP related timer definitions are empty at the moment. Achieved by using osmo_tdef_group API of libosmovty. Change-Id: I6024c104b6101666c8aa1108a043910eb75db9a5 Related: OS#4368

2020-01-15libmsc: SMS, Avoid premature RP-ACK to MSPablo Neira Ayuso2-2/+12
There was one libmsc commit to openbsc that was thus far missing in osmo-msc. This commit completes the work on delayed response from an ESME. Without this patch, the SMR sends an RP-ACK to the mobile station, and subsequently a DELIVER_SM_REPONSE from the ESME provokes either a second RP-ACK, or an RP-ERROR; both of which result in "unhandled at this state (IDLE)" from the SMR After this patch, we have two things corrected: 1) RP-ERROR respects Deliver-SM error cause. 2) No more "unhandled as this state" error from the SMR Extract from original commit message: -------- libmsc: annotate esme route in the sms object from deliver_to_esme() Annotate this esme route, so we can use it to return -EINPROGRESS to skip sending premature RP-ACK to the mobile station, in case we're handling sms routes through SMPP. -------- Fixes: #OS4351 Change-Id: Ic34d398e0a850856e20380ae35e5c2ae5e3c539b

Later on it was discovered that '000'B also crashes OsmoMSC in the same way. The crash itself is provoked by OSMO_ASSERT(0) in vlr_subscr_rx_id_resp(). Let's keep that assert in there, and make sure that: - on receipt of MM Identity Response, Mobile Identity type matches the one in MM Identity Request; - on receipt of RR Ciphering Mode Complete, Mobile Identity contains IMEI(SV) if present.

2019-12-12gsup: indicate CN-Domain in SendAuthInfo RequestsNeels Hofmeyr22-146/+148
In order for osmo-hlr to be able to 100% guarantee distinct INDs for CS and PS, set CN-Domain = CS in all SendAuthInfo Requests. In Milenage auth, it is highly desirable that osmo-hlr guarantees use of distinct INDs for CS and PS domains. If an MSC and SGSN attached at the same time use the same IND bucket to generate Milenage SQN, that collision would rapidly waste SQNs and load osmo-hlr with requesting new auth tuples on each CS/PS Complete-Layer3. So far, osmo-msc did not indicate the CN domain in the GSUP SendAuthInfo Request, which was neither required nor evaluated. The CN-Domain is only sent for the UpdateLocation Request that usually follows later. Related: OS#4318 Change-Id: I22f44068268e62801cadbf6542efaf153423cd65
