2018-06-16code bomb: refactor just about everything for inter-bsc HOneels/inter_bsc_ho_savedNeels Hofmeyr1-1077/+662
This is way too large, yet the typical tangle of modification onto modifications needs to be squashed to make sensible bits of them later for code review... Change-Id: I82e3f918295daa83274a4cf803f046979f284366

2018-06-14absi_rsl: Fix segfault in rsl_rx_conn_fail()Harald Welte1-1/+2
When we receive a RSL CONN FAIL IND, it may be that this happens before any RLL is established (and hence a lchan->conn exists), or after the RLLs have been shut down (and hence a lchan->conn doesn't exist anymore). So in this function, it is not legal to unconditionally dereference lchan->conn. Change-Id: I6380f5d2cd9364560ce3947517c84247cf4af0d4 Closes: OS#3182
2018-06-08log: fix logging in rsl_rx_chan_act_nack()Neels Hofmeyr1-6/+9
In each code path within rsl_rx_chan_act_nack(), do separate logging of the NACK to ensure proper termination of each log line. When receiving a Chan Act NACK, we possibly mixed a LOGP() within an unterminated other LOGP() that had not been ended with a LOGPC() yet. Change-Id: Icd2772b21ef3a2ff5af11b7c92dff0ecb4d87ff0
2018-06-07dissolve libbsc: move all to src/osmo-bsc, link .o filesNeels Hofmeyr1-0/+3040
Move all of libbsc/ into osmo-bsc/, and separate/move some implementations to allow linking from utils/* and ipaccess/* without pulling in unccessary dependencies. Some utilities use gsm_network and gsm_bts structs, which already include data structures for fairly advanced uses. Move initialization that only osmo-bsc needs into new bsc_network_init() and bsc_bts_alloc_register() functions, so that the leaner tools can use the old gsm_* versions without the need to link everything (e.g. handover and lchan alloc code). In some instances, there need to be stubs if to cut off linking "just before the RSL level" and prevent dependencies from creeping in. - abis_rsl_rcvmsg(): the only program currently interpreting RSL messages is osmo-bsc, the utils are merely concerned with OML, if at all. - paging_flush_bts(): ip.access nanobts models call this when the RSL link is dropped. Only osmo-bsc actually needs to do anything there. - on_gsm_ts_init(): the mechanism to trigger timeslot initialization is related to OML, while this action to take on init would pull in RSL dependencies. utils/ and ipaccess/ each have a stubs.c file to implement these stubs. Tests implement stubs inline where required. From src/utils/, src/ipaccess/ and tests/*/, link in .o files from osmo-bsc/. In order for this to work, the osmo-bsc subdir must be built before the other source trees. (An alternative would be to include the .c files as sources, but that would re-compile them in every source tree. Not a large burden really, but unless linking .o files gives problems, let's have the quicker build.) Minor obvious cleanups creep in with this patch, I will not bother to name them individually now unless code review asks me to. Rationale: 1) libbsc has been separate to use it for osmo-nitb and osmo-bsc in the old openbsc.git. This is no longer required, and spreading over libbsc and osmo-bsc is distracting. 2) Recently, ridiculous linking requirements have made adding new functions cumbersome, because libbsc has started depending on osmo-bsc/*.c implementations: on gscon FSM and bssap functions. For example, neither bs11_config nor ipaccess-config nor bts_test need handover_cfg or BSSMAP message composition. It makes no sense to link the entire osmo-bsc to it, nor do we want to keep adding stubs to each linking realm. Change-Id: I36a586726f5818121abe54d25654819fc451d3bf
