8 daysneighbor config: allow re-using ARFCN+BSIC pairsHEADmasterNeels 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.

2019-08-05Remove undefined param passed to logging_vty_add_cmdsPau Espin Pedrol1-1/+1
Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However, definition in C file doesn't contain "(void)", which means number of parameters is undefined and thus compiler doesn't complain. Let's remove parameters from all callers before enforcing "(void)" on it. Change-Id: Ic3c578347864fa225feb6d2dbe14798b9c19ace0 Related: OS#4138

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.

2019-07-08make bsc_clear_request() staticNeels Hofmeyr4-7/+4
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. For now contain legacy code in the static context. Adjust comment. Change-Id: Ic89d0afad42e4b11183a13d2dc6b7bbf0b822fd9

Old osmo-bsc-sccplite already supported this, but in the migration over to libosmo-sigtran and to real 3GPP AoIP, this functionality got lost. We now create a UDP proxy socket. Any MGCP commands received via IPA from MSC (or rather: bsc_nat) are retransmitted to the MGW via UDP on this socket. Any responses back from the MGW received on the UDP socket are retransmitted back to MSC/bsc_nat as MGCP inside the IPA multiplex. Closes: OS#2536 Change-Id: I38ad8fa645c08900e0e1f1b4b96136bc6d96b3ab

2019-05-24chan_alloc: Don't include CBCH channels in load computationHarald Welte1-0/+4
When displaying the channel (lchan) load, we are interested in the dedicated channels as available for communication with mobile stations. If CBCH is enabled, it "steals" one of the SDCCH slots, so we have to exclude this channel from the count of available dedicated channels. Before this patch, A CBCH would show up as "in use" dedicated channel (so both the total and the in_use count were incremented). After this patch, neither "total" nor "use" are affected; The CBCH slot is completely excluded from load statistics. Change-Id: I606962e4977f122ff05a2d4e756c04c7f38bdaa0
