2019-03-28Replace broken ipa_ccm_idtag APIs with new ipa_ccm_id onesPau Espin Pedrol1-3/+1
ipa_ccm_idtag_parse_off is broken, and can only be used with len_offset=1 on ID Request messages, otherwise won't work correctly. Modify ipa_ccm_idtag_parse to at least parse those correctly, and document the limitations. Those two functions are already deprecated and only used in openbsc by 3 callers: * ipa_ccm_idtag_parse in ussd_read_cb(): Broken, that function can only work for Requests and it's used to parse a Response. * ipa_ccm_idtag_parse_off in forward_sccp_to_msc (NAT): Broken, it can only be used to parse Requests and it's used to parse a Response. Furthermore, len_offset=2 is passed which makes no sense and most probably it fails always, or can even make the program crash. * ipa_ccm_idtag_parse_off in (answer_challenge): This one is fine and could actually be replaced with ipa_ccm_id_get_parse after libosmocore commit (see below) is merged. See libosmocore I6efc852dfc041192f554e41a58290a0f63298021 for more information. As a consequence of the fixes, osmo-bsc-nat now parses messages sent from VTY test correctly and thus it goes into processing them instead of silently dropping them. As a result, some VTY tests fail because they are sending incorrect format (missing NULL char in unit id strings) and osmo-bsc-nat closses its connection (due to bad auth).

2017-11-11osmo-bsc-sccplite: Implement incoming RESET procedureHarald Welte2-1/+34
In osmo-bsc-sccplite we so far didn't implement the inbound RESET procedure. We instead ignored any RESET message from the MSC. This commit adds support for RESET: We will destrpy any SCCP connections and acknowledge the RESET to the MSC. As osmo-msc is requiring the BSC to handle an inbound RESET procedure, this commit allows osmo-msc to properly initialize the A interface towards osmo-bsc-sccplite via a translating/routing osmo-stp. While we don't anticipate any new deployments of osmo-bsc-sccplite, making it interoperate with osmo-msc enables us to do more testing of osmo-bsc-sccplite.

2017-10-26osmo-bsc: Initialize logging before initializing rate_ctrHarald Welte1-3/+3
The library code for rate counter initialization, which is called from the descendants of bsc_network_alloc() might already want to log something (particularly after Change-Id Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 in libosmocore), so the logging framework must be initialized before.

2017-03-08add struct bsc_subscr, separating libbsc from gsm_subscriberNeels Hofmeyr4-34/+39
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
2017-02-24cosmetic: rename struct osmo_msc_data to bsc_msc_dataNeels Hofmeyr9-92/+92
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: I0dfbcb7d1a579211180f71319982820d8700afab

2017-02-08vty: remove ignored logging parametersMax1-1/+1
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

2016-12-02Move timezone settings up to network levelNeels Hofmeyr2-30/+24
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
2016-12-02global gsm_network: move allocation further upNeels Hofmeyr1-5/+8
Now that bsc_network_alloc() is separate, move it to before the VTY init (a subsequent patch will pass the gsm_network instance as a parameter to vty_init()). bsc_hack.c: drop the comment that says about the VTY init: "This needs to precede handle_options()" -- it is not accurate. Actually move the handle_options() above both vty_init() and the bsc_network_alloc() calls, to be able to decide which mncc callback to pass to bsc_network_alloc. It would make sense to set this later on, but that would require further refactoring of the bsc_network_init() and gsm_network_init() signatures, so not in this patch.

2016-12-02split bsc_bootstrap_network() in alloc and configNeels Hofmeyr1-2/+6
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 Hofmeyr5-10/+10
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
2016-11-24move to libcommon-cs: net init 3: actual moveNeels Hofmeyr1-0/+1
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.

2016-03-1504.08: apply new bitmask functions, fix bitmask useNeels Hofmeyr2-9/+9
Replace hardcoded protocol discriminator and message type bitmasks with function calls recently introduced in libosmocore. Note that the release 98 bitmasks slightly differ from the release 99 bitmasks. This patch uses the "default" gsm48_hdr_msg_type invocation, thus it depends on libosmocore whether 98 or 99 bitmasks are used. In some places, use of the bitmask was erratic. Fix these implicitly by employing the bitmask functions: * silent_call.c: silent_call_reroute(): add missing bitmask for MM. * bsc_msg_filter.c: bsc_msg_filter_initial(): RR vs. MM messages. * osmo_bsc_filter.c: bsc_find_msc() and bsc_scan_bts_msg(): RR vs. MM messages. * bsc_nat_rewrite.c: bsc_nat_rewrite_msg(): SMS vs. CC messages. * bsc_ussd.c: no bitmask is applicable for the message types used here. * gb_proxy.c: gbproxy_imsi_acquisition(): missing bit mask for pdisc. In gprs_gb_parse.c: gprs_gb_parse_dtap(), add a log notice for unexpected message types.

2015-10-02amr: Attempt to unbreak the AMR support in the BSCHolger Hans Peter Freyther1-11/+25
The signature of mr_config and the BSC implementation didn't match and the compiler was warning about it: osmo_bsc_api.c:530:2: warning: initialization from incompatible pointer type .mr_config = bsc_mr_config, ^ osmo_bsc_api.c:530:2: warning: (near initialization for ‘bsc_handler.mr_config’) Change the mr_config again and provide an implementation that will set the ms and bts data structure. It would be better to put the size outside of the IE but I am not going to change it right now. It would also be nice to either move the AMR setting into the "nitb" structure or have the msc data be used _after_ the bts settings. This needs to be cleaned up in the next step. Manually verified by placing a MO call and checking that both the channel mode modify and the mode modify request contain the multi rate config with the rate mr config (length two bytes, version 1, icmi==1, no start mode being set).
