2017-03-09Use libvlr in libmsc (large refactoring)Neels Hofmeyr6-20/+40
Original libvlr code is by Harald Welte <laforge@gnumonks.org>, polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>. This is a long series of development collapsed in one patch. The original history may still be available as branch neels/vlr_orig. TODO: This commit may be split in several smaller changes before merging to master.

2017-03-08add struct bsc_subscr, separating libbsc from gsm_subscriberNeels Hofmeyr6-54/+239
In a future commit, gsm_subscriber will be replaced by vlr_subscr, and it will not make sense to use vlr_subscr in libbsc. Thus we need a dedicated BSC subscriber: struct bsc_subscr. Add rf_policy arg to bsc_grace_paging_request() because the bsc_subscr will no longer have a backpointer to gsm_network (used to be via subscr->group). Create a separate logging filter for the new BSC subscriber. The implementation of adjusting the filter context is added in libbsc to not introduce bsc_subscr_get/_put() dependencies to libcommon. During Paging Response, fetch a bsc_subscr from the mobile identity, like we do for the gsm_subscriber. It looks like a duplication now, but will make sense for the VLR as well as for future MSC split patches. Naming: it was requested to not name the new struct bsc_sub, because 'sub' is too ambiguous. At the same time it would be fine to have 'bsc_sub_' as function prefix. Instead of struct bsc_subscriber and bsc_sub_ prefix, I decided to match both up as struct bsc_subscr and bsc_subscr_ function prefix. It's fast to type, relatively short, unambiguous, and the naming is consistent. Add bsc_subscr unit test. Related: OS#1592, OS#1594 Change-Id: Ia61cc00e8bb186b976939a4fc8f7cf9ce6aa3d8e
2017-03-02subscriber conn: add indicator for originating RANNeels Hofmeyr1-0/+1
Add via_ran to gsm_subscriber_connection to indicate whether a conn is coming in via 2G/GERAN/A-Interface or 3G/UTRAN/Iu-Interface. Prepares for Iu, but also for libvlr to decide between GSM or UMTS Auth. Until actual Iu support is merged to master, this indicator will aid VLR unit testing. At some point we may also add RAN_GERAN_IU; it's not on the agenda yet, but to clearly distinguish the names if we want to add it, explicitly name the ones we have RAN_GERAN_A and RAN_UTRAN_IU.

2017-02-24cosmetic: rename osmo_msc_data.h to bsc_msc_data.hNeels Hofmeyr4-4/+4
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: I13554563ce9289de126ba0d4cf329bafcda35607
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.

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.

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
