2019-11-02osmo_bsc_main.c: fix CCCH_CONF computation: use pchan_from_configVadim Yanitskiy1-4/+4
As can be seen from include/osmocom/bsc/gsm_data.h: - pchan_from_config - channel configuration from the VTY/config (can be changed from the VTY at runtime, should not affect the existing RSL/OML connections); - pchan_on_init - channel configuration after the OML link is established (pchan_from_config is copied here); - pchan_is - the *actual* channel configuration currently active. Since we call bootstrap_bts() during the initialization, even before establishing any OML/RSL connections, neither pchan_on_init nor pchan_is can be used. Let's use pchan_from_config instead. This change fixes the problem discovered by @mqng2 and reported together with https://gerrit.osmocom.org/c/osmo-bsc/+/15909: CCCH_CONF in System Information Type 3 does not reflect the actual channel configuration, and always indicates a single CCCH combined with SDCCH. This also misleads the lchan allocation algorithm during the MO connection establishment. Change-Id: I8f9d7aa27f24b55732a4de933bc834ed930806fd
2019-11-02osmo_bsc_main.c: simplify computation of CCCH_CONFIGVadim Yanitskiy1-23/+10
Do not count the number of additional CCCHs if TS0 is using combined channel configuration (CCCH+SDCCH4), because they are only allowed if TS0 is not combined with SDCCH. Get rid of the 'switch' statement using the following formula: CCCH_CONFIG = (N << 1) where N is the number of additional CCCHs. Change-Id: I1430500999389e9b30e55ea89a8a5ea5071f7957

NULL or 0.0.0.0 should actually not be used upon connect() calls. Whoever, it worked so far because osmo_sock_init2() calls getaddrinfo() on it which does the 0.0.0.0->127.0.0.1 translation. osmo-msc already passed 127.0.0.1 as default address, so let's do the same here.

2019-09-18bsc_subscr_conn_fsm: Cleanly clear BSSAP conn if associated channel closed ↵Pau Espin Pedrol1-5/+28
during WAIT_CC TTCN3 BSC_Tests.TC_ms_rel_ind_does_not_cause_bssmap_reset seems to sometimes run into a race condition on the order of messages received by osmo-bsc comming from MSC and BTS. Usual (expected) scenario): BTS->BSC EST IND BSC->MSC CL3 Info BSC<-MSC CC BTS->BSC REL IND BTS<-BSC DEACT SACCH BSC->MSC ClearRequest BSC<-MSC ClearCommand BSC->MSC ClearComplete BTS<-BSC RF Chan Release BTS->BSC RF Chan Release ACK Sometimes CC message and REL IND message are received swapped (because they are sent by different components asynchronously in TTCN3). As a result, osmo-bsc was failing to go into CLEARING state and was unable to send the ClearRequest because CC was still not received. So the idea is to stay in WAIT_CC until CC is received, then check if the lchan was dropped and in that case go into clearing state. Change-Id: Id1abf5ee44c60925b478123409f26bd29006202b

2019-09-07a_reset.c: Don't wait 2 seconds to send first BSSMAP RESETPau Espin Pedrol1-4/+3
Function fsm_reset_ack_timeout_cb() could be called directly from within a_reset_alloc(), but it's still desirable to deferr the BSSMAP RESET to be sent asynchronously by the timer upon next main loop step as soon as possible, so whole process is already configured properly. 1ms needs to be set instead of 0 (immediate asynchronous) because value 0 actually disables the timer. As a result, moving the state_chg() after the msc->a.reset_fsm assignment is not really needed, but still makes it more clear that the pointer will be set upon call of the timer callback.

2019-08-28gsm_08_08.c: always pick first msc for unsolicit paging responsesPhilipp Maier1-3/+16
When osmo-bsc receives a paging response via the A-bis interface it tries to find the MSC which is in charge for the paging. This is due to the fact that osmo-bsc supports multiple msc connections, which is not specified by 3gpp specs. In an MT-CSFB call the MSC pages the UE via the SGs interface. Then the UE falls back to 2G. It then reports back as MS on the A-Bis interface with the paging response directly. In those cases osmo-bsc will not be able to determine an MSC in charge, so we will forward the paging response to the first configured MSC.

2019-08-23abis_nm.c: use LOGP() macro instead of LOGPC()Vadim Yanitskiy1-3/+3
The LOGPC() is usually used for continuation when printing complex logging messages (e.g. where using format string is not enough). In this case, nothing is being printed before calling LOGPC(), so the logging messages appear without the meta info (time-stamp, level, category, etc.), for example: BTS 0 reported connected PCU version 0.7.0.1-2585-dirty Change-Id: I868633ad3e50f2cb3ebfb2c566d16c4710f17563
2019-08-13neighbor config: allow re-using ARFCN+BSIC pairsNeels Hofmeyr8-60/+240
Fix neighbor config to match OsmoBSC manual: implement the plan for neighbor configuration that was so far only described in the manual without actually being in operation. This first allows re-using ARFCN+BSIC pairs in and across BSS. So far the handover_start() code always looked for handover target cells across *all* local cells, even if they were not listed as neighbors to a source cell. Imply all cells as neighbors only as long as there are no explicit neighbors configured. As soon as the first 'neighbor' line appears in a 'bts' config, only the listed neighbors are regarded as handover target cells. (The 'neighbor-list' commands are not related to this, only the relatively new 'neighbor (bts|lac|cgi|...)' commands affect actual handover procedures.) TTCN3 tests TC_ho_neighbor_config_1 thru _7 play through the various aspects of neighbor configuration: both the legacy implicit all-cells-are-neighbors as well as allowing only explicit neighbors by config.

2019-07-16logging: introduce LOG_BTS and LOG_TRX and use it everywhereHarald Welte9-105/+89
It's quite ugly to have manual "bts=%d" printf-statements all over the BSC code. Let's change this to use shared logging helper functions all over the place, whenever we need to log something related to one BTS or one TRX. This can also help us as the first step to later add alternative logging of BTS identities, e.g. by printing the Cell Global Identifier or LAC+CI, or even a human-readable/vty-defined 'name' of the BTS, rather than its numeric bts number. With this change in place, we can introduce such changes at a single location in the code. Change-Id: I4a7814d164384eecfb6913c31802cf2faead6e6c

2019-07-09remove double BSSMAP Clear on HO failureNeels Hofmeyr1-8/+0
If a handover fails when the new lchan is already fully established, osmo-bsc so far caused two BSSMAP Clear Requests to be sent out to the MSC: one caused by detaching the lchan from the gscon, one from returning the gscon back to ST_ACTIVE, which detects that no lchan is present and Clears. In fact only one of those is necessary. Checking for the presence of an lchan when entering ST_ACTIVE is an earlier attempt to catch insane situations. Since then, osmo-bsc has acquired other logic that will ensure sending a Clear Request in all cases, see gscon_forget_lchan(). Sending another BSSMAP Clear Request in ST_ACTIVE's onenter is simply not necessary. Drop gscon_fsm_active_onenter() entirely. Note: the double Clear Request is currently hit by TC_ho_out_fail_no_ho_detect(), which currently fails and will pass again after this patch; however, osmo-bsc should actually not release the lchan at all during this test, see OS#4093. In other words, osmo-bsc behavior for this scenario as well as TC_ho_out_fail_no_ho_detect() need to be changed, and the test will, once fixed, not be useful to trigger this issue anymore.

bsc_clear_request() is in fact used only within gsm_08_08.c, make it static to that file. Since the gscon FSM, "real" BSSMAP Clear are sent only by gscon_bssmap_clear(). bsc_clear_request() remains in use for legacy code paths in gsm_08_08.c: - the bsc_filter, i.e. for IMSI filtering; - in move_to_msc(), from handle_cc_setup(), a code path that is in fact not entirely clear to me. It seems to be an old functionality to serve multiple MSCs? Both of which I personally haven't seen in use, are not tested and should probably be completely removed.
