2017-02-23msc_release_connection(): don't call gsm0808_clear()Neels Hofmeyr1-1/+0
gsm0808_clear() is all about clearing lchans. To be able to link libmsc without libbsc, don't call it directly. Change-Id: I149146fc3cb99ef4a21ee2a798231bb070f398cd
2017-02-23cut off libbsc paging, pending paging in libmscNeels Hofmeyr5-2/+24
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. Change-Id: I8b6920ddc54fc3f2876a59664e6722666d8a8a4a
2017-02-23libmsc: duplicate gsm0808 / gsm48 functions (towards BSC)Neels Hofmeyr4-13/+68
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.

2017-02-23gsm_04_08, gsm_subscriber: decouple lac from btsNeels Hofmeyr3-11/+10
The idea is to not have a direct pointer to a bts struct (into BSC land), but a LAC to resolve the BSC or RNC depending on the appropriate A or IuCS interface. subscr_update(): remove bts arg, add lac arg. Pass conn->lac to gsm48_generate_lai() instead of bts->location_area_code. Change-Id: I9f2b298a785bf4b2a1b3fcdd91b8256106b2d9de

2017-02-23Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication.Neels Hofmeyr6-0/+149
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]").

2017-02-23cosmetic: rename struct osmo_msc_data to bsc_msc_dataNeels Hofmeyr14-107/+107
With the OsmoMSC program coming up, the name osmo_msc_data becomes even more confusing than it already is. Clearly indicate it as libbsc's data of a remote MSC by prefixing with bsc_. Also, the Osmocom community has in the meantime agreed to have the osmo_ prefix only in libosmocore, to avoid naming conflicts in case things are moved there. So while renaming anyway, also drop the osmo_ prefix. Change-Id: I0dfbcb7d1a579211180f71319982820d8700afab

2017-02-23logging fixup: shorter names for LOGGING_FILTER_* and LOGGING_CTX_*Neels Hofmeyr5-26/+26
In libosmocore, my patch was merged to master a bit too soon. To accomodate the request for naming that matches the general "LOG" prefix instead of "LOGGING", a fixup was committed to libosmocore.

2017-02-22logging: use central filter and ctx consts from libosmocoreNeels Hofmeyr7-55/+32
The LCHAN and BTS filter contexts are actually never used, so drop them until someone adds them properly. For now use only LOGGING_{FILTER,CTX}_VLR_SUBSCR. Some of these will change to _BSC_SUBSCR once struct bsc_subscriber is introduced, and later on, struct gsm_subscriber will be replaced by vlr_subscriber so that the names will match.

2017-02-19subscr_update_expire_lu(): fix (obscure) segfaultNeels Hofmeyr1-0/+10
To be paranoid, catch a NULL subscriber and/or bts in subscr_update_expire_lu(): print an error log and avoid segfault. (I'm not sure this would really happen in a normal situation.) During aggressive testing of Paging timeout, I came across this segfault in msc_release_connection() when conn->expire_timer_stopped is set but conn->subscr is NULL, at the subscr dereference after: if (conn->expire_timer_stopped) subscr_update_expire_lu(conn->subscr, conn->bts); I brought this situation about by a fabricated Paging fault, i.e. in gsm48_rx_rr_pag_resp() return 0 and don't call gsm48_handle_paging_resp() at all. Thus conn->subscr is still NULL when expire_timer_stopped is 1. When looking at CM Service Request handling, the conn->subscr is set before setting expire_timer_stopped = 1, which is a saner thing to do. But without my mad 'return 0', there is in fact no way to have a NULL subscriber there. It looks like all other code paths already do the same, but it's not that obvious (e.g. _gsm48_rx_mm_serv_req_sec_cb()). So rather catch this case of NULL conn->subscr, and while at it catch NULL bts as well. Change-Id: I430dd952b2b928bea7f8360f1e01bb3cccb0a395

2017-02-08vty: remove ignored logging parametersMax10-12/+12
Since ce9fec3e896571835ac5bfd2980d6836f2b29f0d libosmocore ignores parameters to log_vty_command_* functions. Hence parameter of logging_vty_add_cmds() is ignored too. As we depend on much later libosmocore version anyway, we can simplify code somewhat by removing parameters which will be ignored anyway. Change-Id: I62f752fd88f1d8fefa563648f9864c7c31f87991
