2019-01-12tweak fsm_msc_mgcp FSM and FI nameNeels Hofmeyr1-6/+4
Instead of MGW(MGW_99) use a name of msc-mgcp(MSISDN:2331_GERAN_A:00000017_trans99) 1. The FSM is communication towards an MGW, not the MGW itself. When reading combined logging (gsmtap_log), it is confusing to read 'MGW' in a log coming from the MSC. The API is also called msc_mgcp_*. 2. Calling the FSM instance 'MGW_' again doesn't make sense. 3. Indicate 'trans' before the trans_id (trans_id was already shown, but not indicated what it was). 4. Also indicate the actual subscriber's identification. 5. Also indicate the RAN connection and conn_id. This comes up while trying to understand a call coming in on an already established call: parsing the log with a human brain is near torture without this info, taking extremely long to get grips on.

2019-01-12refactor log ctx for vlr_subscr and ran_connNeels Hofmeyr5-53/+111
ran_conn_get_conn_id(): instead of a talloc allocated string, return a static buffer in ran_conn_get_conn_id(). So far this function had no callers. Refactor ran_conn_update_id() API: during early L3-Complete, when no subscriber is associated yet, update the FSM Id by the MI type seen in the L3 Complete message: ran_conn_update_id_from_mi(). Later on set the vsub and re-update. Call vlr.ops->subscr_update when the TMSI is updated, so that log context includes the TMSI from then on. Enrich context for vlr_subscr_name and ran_conn fi name. Include all available information in vlr_subscr_name(); instead of either IMSI or MSISDN or TMSI, print all of them when present. Instead of a short log, rather have more valuable context. A context info would now look like: Process_Access_Request_VLR(IMSI-901700000014706:MSISDN-2023:TMSI-0x08BDE4EC:GERAN-A-3:PAGING_RESP) It does get quite long, but ensures easy correlation of any BSSAP / IuCS messages with log output, especially if multiple subscribers are busy at the same time. Print TMSI and TMSInew in uppercase hexadecimal, which is the typical representation in the telecom world. When showing the RAN conn id GERAN_A-00000017 becomes GERAN-A-23 - We usually write the conn_id in decimal. - Leading zeros are clutter and might suggest hexadecimal format. - 'GERAN-A' and 'UTRAN-Iu' are the strings defined by osmo_rat_type_name().

2019-01-12add LOG_RAN_CONN() to use the conn->fi->id for contextNeels Hofmeyr4-35/+50
For each conn, set a default logging category, to distinguish categories for BSSMAP and RANAP based conns. LOG_RAN_CONN(): log with the conn's default category, LOG_RAN_CONN_CAT(): log with a manually set category (mostly for keeping previous DMM logging on the same category). In some places, replace LOGP() using manual context with LOG_RAN_CONN(), and remove the manual context info, now provided by the conn->fi->id. This is loosely related to inter-BSC and inter-MSC handover: to speed up refactoring, I want to avoid the need for manual logging context and just use this LOG_RAN_CONN().

2019-01-04fix: incoming call during ongoing callNeels Hofmeyr1-0/+31
If a call is already busy and another call is coming in, do not try to immediately assign an lchan (before this patch, it fails because there already is an mgcp_ctx for the conn). Leave the second CC transaction waiting. When a call is hung up, as soon as the old mgcp_ctx is discarded, look for other CC transactions that are waiting. If there is one, trigger assignment, so a new mgcp_ctx is set up for the new call. This fixes the following scenario: - from A, call B. - from C, call B; B rings during ongoing call. - in B, pick up the call, choose to drop the old call. After this patch, and with osmo-bsc patch with change-id I0c00ec2c120e5008281755adcd4944a3ce4d8355 we are now able to talk to the new caller. I currently haven't tested yet what happens if there is *three* peers trying to talk to the same number, running out of lab phones (not really, just not bothering now). Possibly we should be taking over the particular call indicated by the CC TI; instead, the current patch version takes on whichever waiting call it finds first. This is fine if *one* additional call comes in on an ongoing call, and this is already a huge improvement to what we had before. Related: OS#3735 Change-Id: I0ba216b737909e92080a722db26e3577726c63cb

2019-01-04fix vlr ops.subscr_assoc re-associationNeels Hofmeyr3-9/+25
In rare cases, a conn is already associated with a subscriber. So far, we abort()ed on that, bringing the entire osmo-msc down. Rather log an error and keep the service running. In vlr.ops.subscr_assoc, add success/failure return value, and abort the LU/PARQ on error. I haven't figured out in detail yet why/how a subscriber would re-launch a LU/PARQ on a conn that is already associated, so far it is merely clear that we do not want to crash the MSC if that happens.

2019-01-03release RTP stream only for matching CC transactionNeels Hofmeyr1-0/+6
Do not break the currently ongoing call when rejecting a second incoming caller. There may be multiple (up to seven) simultaneous CC transactions, and there is one mgcp_ctx for the currently active RTP stream. Release the MGCP context only when the active CC transaction is releasing. Before this patch, any CC transaction release would destroy the single MGCP context, possibly breaking the currently ongoing call (another CC trans). This also fixes a possible use-after-free if there were pending MGCP message responses for the MGCP context; they are canceled properly for a released transaction, but since one transaction would free the other transaction's MGCP state, the clean up did not take place and possibly caused an mgcp client response handling to access a freed mgcp_ctx.

2018-12-30libmsc/VTY: introduce kill-switch for routing SMS over GSUPVadim Yanitskiy1-0/+23
As a rudiment of OsmoNiTB, OsmoMSC is still involved in SMS processing, storage (in SQLite DB), and routing (via SMPP). In real networks this is done by the external entity called SMSC (SMS Centre), while the MSC is doing re-encapsulation of GSM 04.11 SM-TL (Transport Layer) payload (i.e. TPDU) between SM-RL (Relay Layer) and MAP. Since OsmoMSC itself is not a 'Network in The Box' anymore, it makes sense to replicate the 'traditional' behaviour of MSC. The problem is that this behaviour cannot co-exist with the current implementation, so the key idea is to rip out the local SMS storage and routing from OsmoMSC, and (re)implement it in a separate process (OsmoSMSC?). As a temporary solution, this change introduces a 'kill-switch' VTY option that enables routing of SMS messages over GSUP towards ESME (through VLR and HLR), but breaks the local storage and routing. This is why it's disabled by default. As soon as we move the SMS processing and storage away from OsmoMSC, this behaviour would be enabled by default, and the VTY option would be hidden and deprecated. At the moment, this option basically does nothing, and will take an effect in the follow-up changes. Change-Id: Ie57685ed2ce1e4c978e775b68fdffe58de44882b Related: OS#3587

2018-12-18vty: show subscriber: put() before printing the use countNeels Hofmeyr1-2/+5
Do not show the VTY command's own use count during 'show subscriber <ID>'. When using 'show subscriber msisdn 2023', I was surprised to see a use count of 2 and suspected a use count leak. With 'show subscriber cache' however, the use count is 1. So I realized it is the vty command's own use count that makes it two, besides the lu_complete=true one.
