2017-07-25MSC,SGSN: use OSMO_GSUP_PORT == 4222 instead of 2222vlr_3GNeels Hofmeyr3-2/+6
In SGSN, actually place the port in the SGSN config by default, so that the gsup port may now be omitted in the VTY config (the IP address suffices). Adjust the osmo-sgsn.cfg example.

2017-05-09mgcp: hack RAB success from nano3G: patch first RTP payloadNeels Hofmeyr2-0/+8
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.

2017-05-08mscsplit: various preparations to separate MSC from BSCNeels Hofmeyr28-268/+446
Disable large parts of the code that depend on BSC presence. 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. 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. In osmo-nitb, paging is done on BSC level and MSC level "at the same time". When the new MSC is fully operational, paging will be controlled separately on the MSC level, and the BSC (RNC) level will be instructed over an IuCS or A-interface to negotiate paging with the MS (UE). This MSC level paging does not yet exist and will be added in subsequent commits. 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 Change-Id: I9cf80f9c2c8a53a29e42f000029e680a9922cb41

2017-05-08Use libvlr in libmsc (large refactoring)Harald Welte66-3825/+2140
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 development collapsed in one patch. The original history may still be available as branch neels/vlr_orig. TODO: This commit may be split in several smaller changes before merging to master. 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.

2017-05-08gsup_client: allow passing a unit id to identify with HLRNeels Hofmeyr4-7/+21
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.

2017-05-02Make pcap dependency optionalMax2-2/+9
Previously we required pcap.h unconditionally which causes embedded build failure because it's not included in current version of out poky toolchain. We can add it to toolchain but it's only necessary for utils/osmo-meas-pcap2db which is not built for sysmobts anyway so it's easier to just make this dependency optional and build osmo-meas-pcap2db only if it's available - similar to the way we build osmo-meas-udp2db.

2017-04-28Prepare for extended SI2quater supportMax7-61/+60
Supporting SI2quater as per 3GPP TS 44.018 will require chnages to the way System Information is stored because it uses 1:n instead of 1:1 mapping between SI type and generated SI content. This should not affect other SI types though. To facilitate this transition: * convert the code to always use GSM_BTS_SI helper instead of accessing buffer directly * make helper more robust by adding extra parenthesis * add similar helper for gsm_lchan * add function estimating number of SI2quater message to hold configured number of (U|E)ARFCNs * add SI2q index/count fields and pass them to rest_octets generator explicitly * internalize buffer access in generate_si* functions Change-Id: I74e4e3cb86364cec869a1472a41b4a95af0d50dd Related: RT#8792

2017-03-31LU counters: count completion and failure, not messages sentNeels Hofmeyr3-20/+38
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. If a conn breaks/vanishes during LU, we cancel the LU without sending any reply at all, so the failed LU would not be counted. Instead, count Location Updating results, i.e. completion and failures. (With the new VLR developments, LU counters need to be triggered in completely different places, and this patch prepares for that by providing sensible counters.)
