2017-02-23logging fixup: shorter names for LOGGING_FILTER_* and LOGGING_CTX_*Neels Hofmeyr2-5/+5
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. Adjust for that. Original patch: change-id I5c343630020f4b108099696fd96c2111614c8067 The fixup: change-id I424fe3f12ea620338902b2bb8230544bde3f1a93 Change-Id: Ib2ec5e4884aa90f48051ee2f832af557aa525991
2017-02-22logging: use central filter and ctx consts from libosmocoreNeels Hofmeyr3-7/+5
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.

2017-02-08vty: remove ignored logging parametersMax1-2/+2
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

2016-12-09Fix TCH/F_PDCH: no need to check ts subslots for PDCHNeels Hofmeyr1-0/+7
For TCH/F_PDCH in PDCH mode, directly return the lchan to use, in order to switch it to TCH/F. To check the pchan type in chan_alloc.c, make ts_pchan() public in gsm_data_shared.h. Commit c3f72f63afde926dfc46827d6880055597515fb6 broke TCH/F_PDCH, as a fallout of setting the GSM_PCHAN_PDCH subslots number to 0. This is sane and correct, but the chan_alloc code failed to see a ts as available if it has no subslots. Explanation: _lc_find_trx() checks each timeslot. For normal, static TCH timeslots we determine the number of logical subslots contained and check whether one of them is free. For dynamic TS, we can do the same when in TCH mode, but when in PDCH mode, we already know that it is available for immediate switchover for voice and hence can return it right away. TCH/F_TCH/H_PDCH already has a special check for that. TCH/F_PDCH doesn't, but this worked for TCH/F_PDCH as long as ts_subslots() returned 1 for PDCH: the for-loop at the bottom of _lc_find_trx() checked one subslot, which succeeded on an lchan in PDCH mode, since PDCH lchans are always marked type == NONE and state == NONE. Now we more accurately acknowledge that a PDCH timeslot has zero subslots and that a dynamic timeslot in PDCH mode can always be switched to voice immediately, without checking lchan type or state. So, above mentioned commit set PDCH to zero subslots, and the for-loop to check the (zero) subslots never ran and hence never returned the lchan. This fix adds a special condition for TCH/F_PDCH in PDCH mode, same as TCH/F_TCH/H_PDCH. (Todo: ts_pchan() can probably be used in other places as well to remove some code dup. Leaving that for another patch.) Fixes: OS#1868 Change-Id: I5d555d018a5bcb8d948e54059d32ec4c9b3070d0

2016-12-09lchan release in error state: SACCH deact only for SACCH pchansNeels Hofmeyr1-1/+15
This is useful particularly in case where we deactivate PDCHs which don't have a SACCH associated. The existin code would always attempt to deactivate a SACCH even in those cases, leading to the BTS responsding with related error messages. Change-Id: Iaf46782329b38ba8f3d438e6c75c2d467b852734

2016-12-02move to libcommon-cs: net timezone VTY configNeels Hofmeyr1-64/+0

2016-12-02Move timezone settings up to network levelNeels Hofmeyr1-32/+33
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 libcommon-cs in subsequent commit). Adjust time zone Ctrl Interface code. Change-Id: I69848887d92990f3d6f969be80f6ef91f6bdbbe8
2016-12-02reinvent connection_for_subscr() and move to libmscNeels Hofmeyr1-33/+0
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.

Move gsmnet_from_vty() and the bsc_gsmnet global to common_cs_vty.c. Rename bsc_gsmnet to vty_global_gsm_network and make it static to common_cs_vty.c, to clearly mark the global variable for VTY use only. Introduce common_cs_vty_init() to set vty_global_gsm_network.

2016-12-02split bsc_bootstrap_network() in alloc and configNeels Hofmeyr1-5/+9
For patch clarity, keep some code dup to be removed in a subsequent patch. In the same sense don't change the fact that mncc_sock_init()'s return value is ignored. The global gsm_network instance 'bsc_gsmnet' is basically only used by the VTY, and a future patch will "hide" that global in a vty .c file. In a nutshell, I want to - first allocate a gsm_network, - then initialize the VTY passing the gsm_network pointer, - and then read the config file using the initialized VTY. So far, bsc_bootstrap_network() allocates the gsm_network and reads the config file right away, which only works by sharing the extern bsc_gsmnet pointer, which I would like to uncouple.

2016-12-02factor out gen of USSD notify and release complete to libosmocoreNeels Hofmeyr2-0/+41
Both libmsc and libbsc will need distinct gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() functions, since there will be distinct subscriber connection structs. Rename to msc_send_ussd_notify() and msc_send_ussd_release_complete(), and add the same in libbsc with bsc_ prefix in new file gsm_04_80_utils.c. In preparation of this patch, the message generation part of these functions has been added to libosmocore as gsm0480_create_ussd_notify() and gsm0480_create_ussd_release_complete(). Use these. Adjust all libmsc and libbsc callers according to use the msc_* or bsc_* implementation, respectively. Change-Id: I33a84e3c28576ced91d2ea24103123431f551173

Used by libbsc, libmsc as well as osmo-bsc and osmo-bsc_nat. Moving gsm48_create* to libcommon-cs affects linking of osmo-bsc_nat, resulting in undefined references to gsm48_extract_mi() and gsm48_paging_extract_mi(); fix that by placing libfilter.a left of libbsc.a upon linker invocation.

2016-11-24move to libcommon-cs: net init 3: actual moveNeels Hofmeyr1-34/+2
Reincarnate gsm_network_init() as the parts not specific to libbsc. Move from bsc_network_init() those bits that are not BSC specific (and useful for upcoming osmo-cscn). Add libcommon-cs to all linkages that use gsm_network_init(). Note: the only requirement to allow linking gsm_network_init() without libbsc is to keep the call to gsm_net_update_ctype() out of libcommon-cs. The other items are kept out of libcommon-cs because it makes sense semantically. But the separation is not strong in that the BSC specific data members are of course still omnipresent in struct gsm_network. If bsc_network_init() is not called, these are not initialized properly -- for now no users of uninitialized members exist. So this is just a first step towards a sensible split of the BSC and MSC gsm_network structs. The long term aim should be to have entirely separate structs with some common general items.

2016-11-24move to libcommon-cs: net init 2: move bsc_network_init decl to new .hNeels Hofmeyr1-1/+1
bsc_network_init() is more fit to live in a BSC specific header, move it to new common_bsc.h. It will probably also absorb the BSC-specific part of gsm_network in the future. Adjust header includes across the board. Particularly, fix abis_nm.h by explicitly including gsm_data.h: it so far relied on other headers to do that, which now is no longer always given.

2016-11-24move to libcommon-cs: net init 1: rename to bsc_network_initNeels Hofmeyr2-2/+4
The gsm_network_init() function initializes a whole lot of BSC specific stuff. Aiming to move some of it to libcommon-cs, first rename it to bsc_network_init(). This will retain the BSC specific stuff when the move is done. Adjust all callers. Future: osmo-cscn will call the more generic part and not the BSC specific part.

2016-11-24define mncc_recv_cb_t to avoid code dupNeels Hofmeyr2-3/+2
Put mncc_recv_cb_t in common_cs.h to avoid header include complications: if placing right above struct gsm_network, one must include gsm_data.h to use mncc_recv_cb_t as function parameter in a header, which will include gsm_data_shared.h, which will include common_cs.h (future knowledge). Since I will need to use mncc_recv_cb_t in common_cs.h, including gsm_data.h from there would introduce an #include loop. Avoid that and define mncc_recv_cb_t in common_cs.h to begin with.
