2017-03-02IuCS and IuPS: add VTY config for RAB Assignment address kindNeels Hofmeyr10-5/+88
To accomodate the ip.access nano3G without having to recompile, make the RAB Assignment's Transport Layer Address IE's format configurable, in both osmo-msc and osmo-sgsn. The long term perspective is to somehow detect which address encoding a given 3G cell prefers, but for the time being just configure it globally and set each ue_conn_ctx to the global setting upon creation. Add VTY command to iu_vty.c, with args passed to iu_vty_init() to insert at an arbitrary VTY node, so that it can be used both for osmo-msc and osmo-sgsn. Add generic iu_vty_config_write() to write out the config. Call iu_vty_init() from msc_vty_init(); msc_vty_init() is in libmsc, hence linking of osmo-msc now needs libiu to come after libmsc, so move that further down.

2017-03-02IuCS, IuPS: move flag to use X.213 NSAP addr into ue_conn_ctxNeels Hofmeyr7-7/+19
The future perspective is to remember the preferred RAB Transport Layer Address encoding for each 3G cell that is connected, so store per UE conn instead of globally hardcoding. Add rab_assign_addr_enc member to ue_conn_ctx. Thus the iu_rab_act_cs() and iu_rab_act_ps() functions no longer need the explicit use_x213_nsap argument. Add include/openbsc/common.h in order to define the enum nsap_addr_enc, in a separate file to be able to easily include it in all of libmsc, libiu and gprs/* without creating include cycles. Set the rab_assign_addr_enc when an MM ctx is created for iu, and whenever the ue_conn_ctx for an Iu MM ctx is updated. This looks a bit clumsy so far, the hope is that there will be a nice way to setup the ue_conn_ctx prior to that. Change-Id: I49bb5736df7bdfdd55d3e7b74ee559595cfd2f7d

It makes sense semantically, and prepares for an upcoming commit that uses the internal global config pointer in sgsn_vty_init(), which would not be defined yet without this. Change-Id: Ie4cf1c0a1c9e6330a134ff4b7b2e6d5699c12bd7
2017-03-02iu: sort out confusion around asn_debug and asn1_xer_printNeels Hofmeyr5-22/+34
Before, I confused asn_debug with asn1_xer_print. Have two distinct VTY commands and fix documentation. Put the asn_debug and asn1_xer_print implementations in iu.c. Since they are globally defined, don't pass a pointer to iu_vty_init() but just use it directly. Might be considered less clean, but is also less bloat.

2017-03-02IuCS: rapidly release connectionsNeels Hofmeyr5-8/+31
Do the same as we do in 2G: release the connection as soon as nothing else is pending for a given subscriber. Before, osmo-msc would wait for the UE "to get bored" and send an Iu release. But the CN should stay lean on connections. Also, 25.413[1] in section 7, 6th point states: "While the Iu release is managed from the CN, the RNC has the capability to request the release of all Iu connection resources from the corresponding Iu connection." So far we did not manage Iu release from osmo-msc at all. Use the same mechanism we use in 2G: from msc_release_connection(), just before freeing the gsm_subscriber_conn, invoke a CN initiated Iu Release command to the UE. This works around OS#1816 ("USSD only works when IuCS is released", on nano3G), because the Iu conn is now released right after every signalling, so that typically no two requests will use the same conn. In iu.h/iu.c, add iu_tx_release(), absorbing almost all of the code from ranap_handle_co_iu_rel_req(). Add stub to db_test.c, necessary to build it without linking libiu.

2017-03-02IuCS: don't remove Iu conn until releaseNeels Hofmeyr1-0/+4
Don't remove the gsm_subscriber_connection without an Iu Release. From the 2G paradigm to close a subscriber connection as soon as nothing else is pending, osmo-msc frequently calls msc_release_connection() to see whether a conn has anything pending, or discards it. In 3G however, we so far don't actively release IuCS connections from the MSC side, but wait until the IuCS is released from the UE side. So the conn is often discarded even though the IuCS stays open and valid, which confuses the situation: before the UE releases a bit later, we would try to page the subscriber unsuccessfully, because the UE expects to already be connected. To first fix the discrepancy of Iu vs. subscr release, never discard gsm_subscriber_connections when msc_release_connection() is called. This creates a "lazy" CN that keeps connections open as long as the UE will tolerate. It is really fast in sending many SMS in close succession, but is certainly a bad CN design choice: we should rather stay lean on connections. A subsequent commit will change this, but I decided to keep this commit as a reference, for when we'd like to test situations that should re-use an established connection.

2017-03-02IuCS: implement msc_call_assignment() for IuCSNeels Hofmeyr4-1/+110
Send IuCS RAB Activation upon MNCC_CALL_PROC_REQ. Implement function msc_call_assignment(): decide between sending A-iface BSSMAP Assignment Request or IuCS RAB Assignment Request. Implement iu_rab_act_cs() to send the IuCS RAB Assignment Request. The IP address and port of the MGCPGW sent in the RAB Assignment are still hardcoded. The A-interface extension is not implemented yet. Declare ranap_new_msg_rab_assign_voice() to avoid including ranap_msg_factory.h, which would require adding ASN1 CFLAGS to Makefile.am. The mgcpgw_client as well as some more osmo-iuh functions are now linked from libmsc, hence add some dummy stubs to libiudummy and db_test.c. Change-Id: Iaae51d1fbbfc28fad1c0b85e161d53d80a420a19

2017-03-02libmgcp: add mgcpgw client APINeels Hofmeyr5-0/+475
Add an API to send MGCP messages to an MGCP GW, from the perspective of an MSC instructing the GW to setup RTP streams. Rationale: the mgcp_protocol.h is mostly for the MGCP GW itself, other implementations forward incoming MGCP messages. So a simpler approach for an MGCP GW client is useful. Add general VTY commands that can be used to configure mgcpgw_client. osmo-msc is going to use this to route RTP streams (for 3G at first). Change-Id: I6fe365c4c89207f2172943cc456b508a207b1135

Rename gsm48_cc_tx_call_proc() to gsm48_cc_tx_call_proc_and_assign() to mark the place where the A-interface will send a BSSAP Assignment Request / where the IuCS-interface will send a RAB Assignment Request. Add function msc_call_assignment() to decide between A-iface and IuCS assignment, to be implemented in subsequent commit. Change-Id: I0695e233d57d13658793b0e63bb7c3ff224909a0
2017-03-02IuCS: send RANAP CommonIDNeels Hofmeyr6-0/+50
Add libiu function to send a CommonID message down a UE connection, iu_tx_common_id(); add also a corresponding stub to libiudummy for linking with tests. Add libmsc function msc_tx_common_id() to call the above. Add this mostly to clearly indicate in msc_ifaces.h that libmsc is calling out of the MSC; also to do conn->via_iface checking. Call msc_tx_common_id() after ciphering is established, in _gsm48_rx_mm_serv_req_sec_cb()'s GSM_SECURITY_SUCCEEDED case. Change-Id: I576ddd5bbabfc989149debd2f8a9743db6d26043

2017-03-02LU counters: count completion and failure, not messages sentNeels Hofmeyr3-12/+8
From a human admin viewpoint it doesn't make sense to count the messages sent: When we use TMSIs, we first send a LU Accept with a new TMSI, and then expect the MS to respond with a TMSI Realloc Complete message. When that fails to come through, the LU actually ends in failure, even though a LU Accept was sent. In 3G, if a UE sends an Iu Release during LU (e.g. user enables flight mode), we cancel the LU without sending any reply at all, so nothing would be counted. Instead, count Location Updating results, i.e. completion and failures.

2017-03-02gsm0408_clear_request(): actually free the released connNeels Hofmeyr1-0/+2
By having conn->in_release == 1, calling msc_release_connection() has no effect and thus never frees the conn. So, after all pending requests have been discarded, also discard and free the unused connection.
