2016-11-12cut off libbsc paging, pending paging in libmscNeels Hofmeyr3-1/+21
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 CSCN 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. Change-Id: I8b6920ddc54fc3f2876a59664e6722666d8a8a4a
2016-11-12libmsc: duplicate gsm0808 / gsm48 functions (towards BSC)Neels Hofmeyr3-13/+61
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 relatd to msc_gsm0808_tx_cipher_mode() in two places.

Pass conn->lac to gsm48_generate_lai() instead of bts->location_area_code. Change-Id: I9f2b298a785bf4b2a1b3fcdd91b8256106b2d9de

2016-11-12Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication.Neels Hofmeyr3-0/+86
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 via_iface marker to gsm_subscriber_connection with enum values IFACE_A and IFACE_IU so far. Add Iu specific fields in a sub-struct: 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]").

Rename current subscr_con_allocate() and subscr_con_free to bsc_*, and add two separate msc_subscr_con_allocate() and _free(). The msc_subscr_con_free() ignores all lchan members. In libbsc use bsc_*, in libmsc use msc_*. Change-Id: I3cf7c7cafdf4672ec7b26058bba8a77159855257 Future: there will be distinct subscr conns for libbsc and libmsc.
2016-11-12Move timezone settings up to network levelNeels Hofmeyr1-9/+8
Time zone used to be configurable per-BTS. In the upcoming MSC-split, no BTS structures will be available on the MSC level. To simplify, drop the ability to manage several time zones in a core network and place the time zone config on the network VTY level, i.e. in gsm_network. If we are going to re-add fine grained time zone settings, it should probably be tied to the LAC. Adjust time zone VTY config code (to be moved to libxsc in subsequent commit). Adjust time zone Ctrl Interface code. Change-Id: I69848887d92990f3d6f969be80f6ef91f6bdbbe8
2016-11-12reinvent connection_for_subscr() and move to libmscNeels Hofmeyr1-0/+14
Implement connection_for_subscr() from a completely different angle: instead of looking up lchans in bts structs, look up the subscriber in the global list of gsm_subscriber_connection. static lchan_find() is thus obsoleted. All callers of connection_for_subscr() live in libmsc, so move to libmsc. The move and edit are done in a single commit since the old and new implementation have nothing in common. Future: osmo-cscn will use this, without bts being present. Remove implementation of connection_for_subscr() from channel_test.c -- it is possible that the abort() in there was intended for a regression test, but actually it seems the implementation was merely added for linking reasons, and the abort() added to guard against the NULL return value: no comment nor the commit log indicate that the abort() is test critical; the addition was the only change in channel_test.c for that commit; at the same time a connection_for_subscr() call was added in libmsc.

2016-11-12sms_next_rp_msg_ref(): use direct pointer to next_rp_ref counterNeels Hofmeyr3-39/+1
libbsc and libmsc will have separate subscriber connection structs. Hence don't rely on gsm_subscriber_connection, but work on a direct pointer to the counter for the next RP reference. The only very thin function in gsm_04_11_helper.c thus becomes obsolete: drop the entire file. Change-Id: I2a2e9ba6a981a385d1f8f07acbe03536ffed0072
2016-11-12move to libxsc: factor out gen of USSD notify and release completeNeels Hofmeyr2-26/+6
Both libmsc and libbsc will need distinct gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() functions, since there will be distinct subscriber connection structs. The current functions live in libmsc, so add the same in libbsc in new file gsm_04_80_utils.c. To avoid too much code dup, move the message generation part of gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() to new functions gsm0480_gen_ussdNotify() and gsm0480_gen_releaseComplete(), placed in libxsc.

2016-11-02mncc_builtin: Properly reject DTMFlynxis/masterHarald Welte1-0/+2
As per TS 23.014, a GSM MSC must implement mobile-originated DTMF generation. We gate the DTMF signalling messages to MNCC, and expect the external MNCC handler to deal with it. However, the internal MNCC handler simply ignored such singalling messages, rather than rejecting DTMF altogether. It turns out failure to respond to START DTMF will cause some phones to behave in interesting ways, particularly with modem firmware v6.01.00, see https://osmocom.org/issues/1817). In this case the phone is not able to release the call as the pending response to the START DTMF is probably keping a reference or lock of some sort.

If IMSI match the regexp than MS is allowed to access the network. If subscriber is already marked as authorized in HLR than it'll be allowed regardless of IMSI matching. The same way we can decide whether to create subscribers on-demand basesd on IMSI regexp match. Similar to authorization this restriction can be overridden by manually creating subscriber via vty, ctrl interface or directly in HLR.

2016-05-15db.c: implemented incremental migrationVadim Yanitskiy1-18/+35
In the past, normal migration was possible only if the actual schema version differed from the version used in DB by 1. For example, if DB uses an old version 3 and you need to use it with the code written for version 5, the check_db_revision() will convert it to 4 and DB will still use incompatible schema version during Osmo-NITB running time. After next run it will be converted to version 5. This patch replaces a set of 'else-if' checks by a 'switch' without 'break' statements between 'case' labels (waterfall). It makes you able to migrate from current version to the latest despite any difference between them.

Rather than having a 'private' structure for kc, sres and rand, we now finally (with 4 years delay) use osmo_auth_vector from libosmogsm, which encapsulates authentication vectors that can be either GSM triplets or UMTS quintuples or a combination of both. gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding use_count and key_seq to it. key_seq is no longer initialized inside gprs_gsup_messages.c, as there is no CKSN / key_seq inside the message anyway.
