2016-04-29oap_message.h: Remove dependency to openbsc includeHarald Welte4-2/+4
This is a first step to moving oap_messages.h to libosmocore
2016-04-29Move osmo_gsup_messages.[ch] to libosmocoreHarald Welte10-877/+14
This requires the corresponding commit in libosmocore.
2016-04-29move utils.h functions to libosmocoreHarald Welte10-339/+12
This needs the corresponding commit in libosmocore which imports the related functions
2016-04-29osmo_gsup_messge.[ch] documentation update (doxygen)Harald Welte2-3/+25
2016-04-29gsup_messages: Add UMTS AKA related encoding/decoding supportHarald Welte2-0/+53
2016-04-29move osmo_shift_* / osmo_match_shift_* to libosmogsmHarald Welte3-185/+0
2016-04-29rename gprs_shift_*() to osmo_shift_*()Harald Welte5-53/+92
This rename is the first step of moving the associated functions into libosmocore. Also, rename gprs_match_* to osmo_match_shift_* to indicate that it is not just matching the TLV, but also shifting the data portion.
2016-04-29Rename gprs_gsup_* to osmo_gsup_*Harald Welte6-228/+229
This is a preparation to move the related code to libosmocore, whilst at the same time generalizing it from GPRS Subscriber Update Protocol to the Osmocom Generic Subscriber Update Protoco.
2016-04-29use new libosmocore gsm_23_003.h for IMEI/IMSI lengthHarald Welte12-22/+25
... rather than our private definitions everwhere. As an added benefit, gprs_gsup_messages.h is now free of any header dependencies within openbsc.
2016-04-29move gsm_04_08_gprs.h to libosmocoreHarald Welte21-557/+14
This requres the corresponding commit in libosmocore.
2016-04-29Start to use struct osmo_auth_vector from gsm_auth_tupleHarald Welte12-70/+69
Rather than having a 'private' structure for kc, sres and rand, we now finally (with 4 years delay) use osmo_auth_vector from libosmogsm, which encapsulates authentication vectors that can be either GSM triplets or UMTS quintuples or a combination of both. gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding use_count and key_seq to it. key_seq is no longer initialized inside gprs_gsup_messages.c, as there is no CKSN / key_seq inside the message anyway. If a usre of the code needs key_seq, they need to manage it themselves.
2016-04-29Disconnect calls with incompatible channel types / modesMax1-1/+45
In case both TCH/H and TCH/F or different codecs are configured and internal MNCC handler is used we might end up in a situation where call legs with incompatible channel types or codecs would be connected resulting in a broken audio. Disconnect such calls with appropriate error message. Fixes: OS#1663
2016-04-29Adjust si2quater rangesMax1-5/+6
Change ranges of arguments for si2quater neighbor lists to proper values according to 3GPP spec.

2016-04-25RAB: add debug log for PS RAB assignmentNeels Hofmeyr1-0/+4
2016-04-25RAB parameters: apply use_x213_nsap parameter additionNeels Hofmeyr4-5/+8
Add use_x213_nsap parameter to iu_rab_act_ps(), pass the new parameter from two callers as 1 such that there is no functional change.
2016-04-25paging_signal_data: remove unused lac memberNeels Hofmeyr2-2/+0
2016-04-25paging response: remove extraneous null check, assert conn and msg further upNeels Hofmeyr1-1/+4
In handle_paging_response(), don't check conn against NULL after using it all the time anyway. To ensure beyond doubt that it is actually never NULL, assert conn further up in the call stack, i.e. in gsm0408_dispatch(), the main entry point for receiving data from the BSC/RNC level. Also assert msg while at it. Fixes: CID#93769
2016-04-23Add missing includeMax1-0/+1
2016-04-22Add extra debug output with channel mode and typeMax4-9/+27
This provides helpful information for debugging internal MNCC handler.
2016-04-22Add vty check for max si2quater sizeMax5-42/+60
Explicitly check if added (U|E)ARFCN will fit into available si2quater message.
2016-04-22Add basic UARFCN supportMax9-46/+369
* add data structures, generation functions * vty interface for neightbor UARFCNs specific to SI2quater * vty test * unit test Fixes: OS#1666
2016-04-22Cleanup shared data structureMax1-2/+1
* remove unused variable. * lower max number of (e|u)arfcns to more realistic value.
2016-04-22Fix earfcn deletionMax2-2/+16
* fix typo in arg index * fix sign in error reporting * add vty test
2016-04-22Fix documentation for command parametersMax1-1/+2
2016-04-20add preliminary paging response handling, incompleteNeels Hofmeyr3-19/+59
In gsm_04_08.c, add a static handle_paging_resp() to take over from the libbsc function gsm48_handle_paging_resp(). Use the subscr->requests listing to handle a Paging Response and call the pending cbfn. In NITB, this used to be done via BTS, and I haven't entirely resolved yet how exactly to rewire this in standalone libmsc. So far, this "works for me", but is worth another visit. Still missing: enable Integrity Protection.

2016-04-20IuCS auth: generate auth tuples, factor outNeels Hofmeyr1-11/+32
Factor out hardcoded-Ki and auth tuple creation into a static function. Add generation of fresh random bytes and generate a valid auth tuple so that the authentication token is different for every MM Auth.
2016-04-20cscn: enable SMS queue (by removing an '#if 0')Neels Hofmeyr1-2/+0
2016-04-20cscn: enable 'subscriber' vty commands for libmscNeels Hofmeyr2-1/+1
This involves removing the openbsc_vty_print_statistics() from vty_interface_layer3.c, as this would link across the MSC/BSC border.

2016-04-20Add Iu pagingNeels Hofmeyr4-3/+104
Add iu_page_cs() and iu_page_ps() API, also add to libiudummy for linking in tests. Implement msc_paging_request() by calling iu_page_cs().
2016-04-20iu.c: add registry of RNC-Ids in LACsNeels Hofmeyr3-2/+130
Introduce struct gsm_rnc, stored in a global list, static to iu.c. (This list is not part of gsm_network so that the code can be used from both MSC and GPRS code, i.e. both for CS and PS.) Parse RANAP Global RNC Id, add GSM flags to build for gsm48_mcc_mnc_from_bcd() to decode the PLMN Id. Upon every Initial UE message, record/verify RNC Id and LAC for that connection. In case of mismatch, so far just log an error.
2016-04-19iu.c: introduce talloc_iu_ctxNeels Hofmeyr1-3/+6
Introduce talloc_iu_ctx, setup during iu_init() as child of the talloc_ctx passed in by the caller. Allocate ue_conn_ctx from talloc_iu_ctx, used to be from NULL. Allocate osmo_sua_user and talloc_asn1_ctx from talloc_iu_ctx, used to be from the ctx passed in by iu_init() caller.

2016-04-16nat/ussd: Add an example of the USSD gateway side-channelHolger Hans Peter Freyther1-0/+65
This adds a very basic, use once example in python on how to connect and deal with the app specific payload and messages. The code is not complete as the invokeId should be patched according to the initial invoke. This excercise is left to future readers of that code.
2016-04-16nat/vty: Do not print token update statementHolger Hans Peter Freyther1-4/+1
On start this would print one line per BSC and this doesn't add a lot of value. Let's just remove this logging message.
2016-04-16Add basic SI2quater supportMax10-4/+391
* support for sending arbitrary static SI2quater. * vty interface for neightbor EARFCNs specific to SI2quater. * dynamic generation of SI2quater messages. * unit test for SI2quater messages. Fixes: OS#1630
