* LCLS: add string dump helpersMax2019-02-261-0/+2
| | | | | | | | | Add functions to dump LCLS (without GCR) and GCR. Dumping entire struct results in inconveniently long string hence the separate functions. Both use talloc functions so they expect caller to take care of providing proper allocation context and freeing memory. Change-Id: Ic3609224c8f3282d667e75f68bc20327e36eb9e6

* gsm/gsm0480: introduce gsm0480_create_release_complete()Vadim Yanitskiy2019-02-081-0/+2
| | | | | | | | | | | | In OsmoMSC, it's required to be able to specify a particular GSM 04.07 transaction ID for GSM 04.80 Release complete message instead of the hard-coded value, that is used gsm0480_create_ussd_release_complete(). Let's finally deprecate gsm0480_create_ussd_release_complete(), and introduce a new function without USSD prefix, as this message is also used in other "structured" supplementary services.

* gsm0808: Add CSFB indication IE to BSSMAP CLEAR COMMANDPhilipp Maier2019-02-051-0/+1
| | | | | | | | | | | When a call that was established in a CSFB context ends the CLEAR COMMAND that is send from the BSC to the MSC should contain a CSFB indication IE, which consists of just the IE byte itsslef. This additional IE tells the BSC to include other CSFB related IEs into the RR Release message. Change-Id: Id8a75e1da2d5f520064666e4ee413d1c91da6ae3 Related: OS#3778
* add osmo_classmark_* APINeels Hofmeyr2019-01-291-0/+7
| | | | | | | | | osmo-bsc and osmo-msc implement identical Classmark structures. It makes sense to define once near the gsm48 protocol definitions. Also move along some generic Classmark API from osmo-msc. Change-Id: Ifd27bab0380f7ad0c44c719aa6c8bd62cf7b034c
* gsm0808: add BSSMAP Cell Identifier matching APINeels Hofmeyr2019-01-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Add * osmo_lai_cmp() (to use in gsm0808_cell_id_u_matches()) * osmo_cgi_cmp() (to use in gsm0808_cell_id_u_matches()) * gsm0808_cell_id_u_match() (to re-use for single IDs and lists) * gsm0808_cell_ids_match() * gsm0808_cell_id_matches_list() * Unit tests in gsm0808_test.c Rationale: For inter-BSC handover, it is interesting to find matches between *differing* Cell Identity kinds. For example, if a cell as CGI 23-42-3-5, and a HO for LAC-CI 3-5 should be handled, we need to see the match. This is most interesting for osmo-msc, i.e. to direct the BSSMAP Handover Request towards the correct BSC or MSC. It is also interesting for osmo-bsc's VTY interface, to be able to manage cells' neighbors and to trigger manual handovers by various Cell Identity handles, as the user would expect them.

Place the Luhn checksum code in a dedicated osmo_luhn() function, so it can be used elsewhere. Related: OS#2541 Change-Id: Id2d2a3a93b033bafc74c62e15297034bf4aafe61
* port rest octets encoding code from osmo-bscStefan Sperling2019-01-121-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | As part of fixing issue OS#3075, we want to migrate support for encoding system information from osmo-bsc to libosmocore. This change ports osmo-bsc code for encoding SI rest octets. The conversion was a bit tricky in some places because some functions receive a 'struct gsm_bts' parameter in osmo-bsc. In this libosmocore version, such functions expect parameters which correspond to the individual fields of 'struct gsm_bts' which are used by these functions. Several structs from osmo-bsc's system_information.h are now also declared in libosmocore headers, with an added osmo_ prefix to avoid collisions with existing definitions in osmo-bsc. Some helpers were ported from osmo-bsc's system_information.c to libosmocore's gsm48_rest_octets.c. Contrary to osmo-bsc's implementation they are now only visible within this file. Unfortunately, this code ported from osmo-bsc lacks unit tests. Change-Id: I47888965ab11bba1186c21987f1365c9270abeab Related: OS#3075
* port arfcn range encode support from osmo-bscStefan Sperling2019-01-121-0/+9
| | | | | | | | | | | | | | As part of fixing issue OS#3075, we want to migrate support for encoding system information from osmo-bsc to libosmocore. This change ports one of the prerequisites for doing so: osmo-bsc code for range-encoding ARFCNs, including tests. An osmo_gsm48_ prefix has been prepended to public symbols in order to avoid clashes with existing symbols in osmo-bsc code. Change-Id: Ia220764fba451be5e975ae7c5eefb1a25ac2bf2c Related: OS#3075

* gsm_utils: add enum osmo_rat_type, from osmo-msc enum ran_typeNeels Hofmeyr2019-01-031-0/+2
| | | | | | | | | | | | | | | In the MSC, we have RAN types GERAN_A and UTRAN_IU, now we need a similar enum in osmo-hlr's GSUP client. Naming: in the MAP specifications, the RAN type is mostly called RAT type, (Radio Access Network vs. Radio Access Technology?). Since GSUP is more about MAP messages, I'm calling the enum osmo_rat_type. Rationale: osmo-msc and osmo-sgsn want to tell the osmo-hlr which RAT a subscriber is calling on. A subsequent patch will extend the GSUP protocol and add a RAT types IE. Change-Id: I659687aef7a4d67ca372a39fef31dee07aed7631
* LCLS: enc/dec entire parameter set instead of GCRMax2018-12-231-2/+2
| | | | | | | | | | | | | In 3GPP TS 48.008 the Global Call Reference IE is only used in HANDOVER REQUEST (§3.2.1.8) and ASSIGNMENT REQUEST (§3.2.1.1) messages which also include LCLS Config and CSC parameters. Hence, there's no point in using GCR encode/decode functions alone. Introduce gsm0808_dec_lcls() and gsm0808_enc_lcls() as trivial wrappers on top of GCR enc/dec routines which are made static. Adjust tests accordingly. Test output intentionally left unchanged. Change-Id: Icfbb2404e1a1d500243e2071173299b557369335
* GSUP/SMS: introduce MO-/MT-FORWARD-SM messagesVadim Yanitskiy2018-12-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to 3GPP TS 29.002, there are two services: - MAP-MO-FORWARD-SHORT-MESSAGE (see 12.2), - MAP-MT-FORWARD-SHORT-MESSAGE (see 12.9), which are used to forward MO/MT short messages. This change replicates both services as GSUP messages: - OSMO_GSUP_MSGT_MO_FORWARD_SM_*, - OSMO_GSUP_MSGT_MT_FORWARD_SM_*. Please note, that only the 'must-have' IEs are introduced by this change, in particular the following: - OSMO_GSUP_SM_RP_MR_IE (see note below), - OSMO_GSUP_SM_RP_DA_IE (see 7.6.8.1), - OSMO_GSUP_SM_RP_OA_IE (see 7.6.8.2), - OSMO_GSUP_SM_RP_UI_IE (see 7.6.8.4), - OSMO_GSUP_SM_RP_MMS_IE (see 7.6.8.7), - OSMO_GSUP_SM_RP_CAUSE_IE (see GSM TS 04.11, 8.2.5.4), where both SM_RP_DA and SM_RP_OA IEs basically contain a single nested TV of the following format: - T: identity type (see 'osmo_gsup_sms_sm_rp_oda_t'), - V: encoded identity itself (optional). According to GSM TS 04.11, every single message on the SM-RL has an unique message reference (see 8.2.3), that is used to link an RP-ACK or RP-ERROR message to the associated (preceding) RP-DATA or RP-SMMA message transfer attempt. In case of TCAP/MAP, this message reference is being mapped to the Invoke ID. But since GSUP has no 'Invoke ID' IE, and it is not required for other applications (other than SMS), this change introduces a special 'SM_RP_MR' IE that doesn't exist in MAP.

* gsm0808: add encoder for cause codes and use itPhilipp Maier2018-12-081-0/+1
| | | | | | | | | | | | | | | | At the moment the all gsm0808 cause codes are encoded directly using the tlv API directly to put a one byte TLV field. This works ok for most situations where the cause code consists of a single byte. However, gsm0808 specifies a two byte cause code model where cause codes may be extended up to two bytes. Instead of implementing the encoding over and over and again, let's rather have an encoder function we can call. - Add an encoder function that can generate single byte and extended cause codeds and makes the length decision automatically. - Use only this function to append cause codes Change-Id: I71d58fad89502a43532f60717ca022c15c73f8bb

* gsm: Deprecate buggy gsm_arfcn2band API and introduce gsm_arfcn2band_rcPau Espin Pedrol2018-11-201-0/+1
| | | | | | | | | | | | | | | | | | | ARFCNs are values in well defined ranges. Until this patch, ARFCNs not belonging to any band were blindly assigned to DCS1800 by gsm_arfcn2band, causing unnoticed bugs and misconfigurations in osmo-bsc. Previous API gsm_arfcn2band cannot accomodate this kind of check easily, so let's deprecate it to tell people to use a new API gsm_arfcn2band_rc which performs this kind of checks and allows callers to log failures, misconfigurations, etc. At the same time, modify implementation of gsm_arfcn2band to abort if an invalid ARFCN is passed, this way users of this API can notice they are passing wrong data to it that most probably will produce unexpected results.

* Deprecate ipa_ccm_idtag_parse() with ipa_ccm_id_{get,resp}_parse()Harald Welte2018-08-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the past, the function ipa_ccm_idtag_parse() was used to parse the payload of IPA CCM ID RESP packets. However, the function was based on a possible misunderstanding of the message encoding, and callers actually counted the first (upper) length nibble as part of the header and passed a pointer to the second (lower) length nibble of the first TLV into this function. As such, it was unfixable, and had to be replaced with a new function called ipa_ccm_id_resp_parse(). At the same time, we also add ipa_ccm_id_get_parse() to parse the slightly different format of the IPA CCM ID GET payload. We can never be 100% sure what is "correct", as our understanding of the protocol is entirely based on protocol analysis, without any official documentation available. This patch also introduces unit test coverage for both of the new functions. Revert "ipa: Add libosmogsm.map entry for ipa_ccm_idtag_parse_off" This reverts commit 7f31c90b80c08fbfe2d84d70d397402fdb38b94c. Revert "ipa: Properly parse LV stream of a ID_GET request" This reverts commit f558ed4bb9c0f00997b8f97c2b251a574c1a64c4. It introduced a function/behavior that was not originally intended: The parse of IPA CCM ID GET (8bit length followed by 1 byte tag and variable-length payload) instead of the IPA CCM ID RESP (16bit length followed by 1 byte tag and variable-length payload).

| | | | | | | | | | Contrary to the existing gsm0480_create_ussd_resp(), the new function only generates the value part of the FACILITY IE, and not the IE Tag/Length or the 04.08 L3 header. This is needed in the context of GSUP-encapsulated USSD, as here we don't work with L3 messages, but only pass on the FACILITY IE value. Change-Id: Ide240279240322f643e142229eb7829f538c6314
