* Add function to make Uplink MeasurementMax2016-05-171-0/+4
| | | | | | | | | | | It assembles RSL Uplink Measurement IE according to 3GPP TS 08.58 ยง9.3.25. The function is based on lchan_build_rsl_ul_meas() from OsmoBTS but optionally includes DTX information.

* GSUP: Add support for RAND in SendAuthInfo.reqHarald Welte2016-05-061-0/+1
| | | | | | In the autentication re-sync case, we need not only the AUTS from the MS/UE, but also the RAND that we sent as part of the failed authentication challenge.
* GSUP: Add OSMO_GSUP_CN_DOMAIN_IE to differentiate CS and PS planeHarald Welte2016-05-061-0/+7
| | | | | We're starting to use GSUP for circuit-switched (CS) plane, so we need to differentiate the two planes somehow from each other.
* import gprs_gsup_message.[ch] from openbsc as gsup.[ch]Harald Welte2016-05-061-0/+139
| | | | | | | Move those routines from OpenBSC to libosmogsm, so they can be re-used from other programs. I think it was a mistake to add them only inside the openbsc repository in the first place. We need to pay more attention to this in the future.
* tlv: Import osmo_shift_* and osmo_match_shift_* from openbscHarald Welte2016-05-051-0/+11
| | | | | These routines have nothing to do with specifically the BSC, so import them to the TLV parser we keep in libosmogsm.
* add new header file for TS 23.003Harald Welte2016-05-051-0/+23
|
* import gsm_04_08_gprs.[ch] from openbsc.gitHarald Welte2016-05-051-0/+397
| | | | | | The definitions in this header file (and associated strings in the c file) are generic about the GPRS Layer3 signalling protocols, and thus should be part of the library.
* add two missing files (gsm0503.h / conv_gen.py) to previous commitHarald Welte2016-04-291-0/+74

* Add function for appending range1024 to bitvecMax2016-04-231-0/+13
| | | | | Add convenience function to append range1024 encoded data (see 3GPP TS 44.018 Annex J) to a given bitvec.
* Deprecate comp128Max2016-04-221-2/+6
| | | | | Mark function as deprecated to discourage its usage: people should use generic API in osmocom/crypt/auth.h
* Deprecate osmo_a5_1 and osmo_a5_2Max2016-04-221-2/+3
| | | | | Mark the functions as deprecated to discourage their use: people should use unified osmo_a5 which supports all the A5/1-4 ciphers.
* Addditional classmark check against A5/4 supportMax2016-04-221-1/+13
| | | | | Add classmark check function according to GSM 04.08 Chapter 10.5.1.7 Fix interface to use unsigned for unsigned value.
* Add function to get osmo_earfcn bit sizeMax2016-04-161-0/+1
| | | | | | This function returns the number of bits necessary to pack osmo_earfcn into Repeated E-UTRAN Neighbour Cells IE (3GPP TS 44.018 Table 10.5.2.33b.1).
* Export names for gsm_chan_t and gsm48_chan_modeMax2016-03-302-0/+7
| | | | This can be used with get_value_string() to improve debugging output.
* add missing #include <stdbool.h>Harald Welte2016-03-171-0/+1

* Add basic EARFCN supportMax2016-03-171-1/+31
| | | | | | Add structure representing group of EARFCNs with common priority, threshold etc. Add functions to populate this structure.
* gsm48: factor out MCC+MNC BCD parsing for re-use in UMTSNeels Hofmeyr2016-03-151-0/+3
| | | | | | | | | | For 3G, I need a BCD composer/parser similar to gsm48_generate_lai()/ gsm48_decode_lai(). Those functions also handle a trivial extra member (lac) which I don't need in this way for 3G. So create new functions to take on the MCC+MNC BCD handling and call those from gsm48_generate_lai() and gsm48_decode_lai(). In this way, the 3G code in openbsc can use only the BCD functionality without code duplication.
* 04.08: add inline funcs for transaction id bitsNeels Hofmeyr2016-03-151-0/+19
| | | | | | Various users of gsm48_hdr apply the same hardcoded shifts/bitmasks to obtain the transaction ID encoded in the upper nibble of the protocol discriminator. Centralize. Patch for openbsc.git will follow.
* 04.08: switch to r99 msg type bitmasks by defaultNeels Hofmeyr2016-03-151-1/+1
| | | | | [hfreyther: Separated from the previous patch to allow an easy revert]
* 04.08: add inline funcs for pdisc + msg type bitmasksNeels Hofmeyr2016-03-151-0/+56
| | | | | | | | | | | | | | | | Add inline functions for both release <= 98 and release >= 99 as well as a default define. Use the release 98 by default since the current code base uses the r98 bitmasks. These inline functions relieve callers of the decision on masking bits of the protocol discriminator and message type octets. Also add a define for the protocol discriminator extension to one octet length (GSM48_PDISC_EXTEND). Apply new pdisc function in gsm0480.c. [hfreyther: Make the hdr param const]
* Add support for SI2quater messagesMax2016-03-111-0/+7
| | | | Add basic data structure for System information Type 2quater.
* fix gsm_7bit_decode API comment: septets, not octetsNeels Hofmeyr2016-02-291-1/+2

* Extend L1SAP PH-DATA with presence informationMax2016-02-221-0/+11
| | | | | | | | | Previously the presence of header and data blocks were communicated in-band which decreases code readability and makes it unnecessary hard to add support for new hardware. Note: OsmoBTS have to be modified to take advantage of extended ph_data_param structure.
* gsm: Add APN conversion functionsJacob Erlbeck2016-01-151-0/+3
| | | | | | | | | | | | These functions are currently part of openbsc but also needed by other projects. The function have been renamed as follows: gprs_apn_to_str -> osmo_apn_to_str gprs_str_to_apn -> osmo_apn_from_str Sponsored-by: On-Waves ehf

* ipa: Properly parse LV stream of a ID_GET requestHolger Hans Peter Freyther2015-06-021-0/+3
| | | | | | | | For some reason the structure is closer to be a LV (length and value). The value is actually a tag but it is counted inside the length. Introduce an overload of the parse function to provide an offset for the length. This will be taken from the returned length.
* Add APN utility function to libosmogsmHarald Welte2015-05-251-0/+13
| | | | | | The current functions are used to 'qualify' an APN from the user-supplied APN name (name identifier) towards the fully-qualified APN name which is used in the .grps DNS zone.

* Supplementary Services (de)activation, interrogation addedTobias Engel2015-01-012-1/+152
| | | | | | | | | | | | | These patches enhance the Supplementary Service (SS) processing from only being able to handle USSD to other SS, specifically activation, deactivation and interrogation of those SS. Registration is not yet implemented. include/osmocom/gsm/protocol/gsm_09_02.h has been added with needed values for SS. Modified by Harald Welte to keep the old ussd-only functiosn for API/ABI stability.

* ipa: Add forward declaration of struct osmo_fdJacob Erlbeck2014-12-221-0/+2
| | | | | | | | | | | A pointer to struct osmo_fd is used in a few prototypes declared in gsm/ipa.h, but is neither declared explicitly nor is such a declaration reachable via the given include directives. This patch adds a forward declaration of this type to ensure proper compilation. Sponsored-by: On-Waves ehf
* ipa: Make a reservation for the GSUP protocolHolger Hans Peter Freyther2014-12-141-0/+1
| | | | | GSUP is a protocol to have the OpenBSC SGSN talk to an exterbal system for 3GPP MAP connectivity.
* gsm48.h: define the reserved TMSI in libosmocore, not openbscHarald Welte2014-08-241-0/+3
|
* ipa: rename functions for consistencyHarald Welte2014-08-201-12/+12
| | | | | | | | As we are breaking builds by moving functions from libosmo-abis to libosmocore anyway, we might as well give functions more appropriate names. ipaccess is a company, while IPA is the multiplex protocol, and CCM is the protocol used for establishing identities on the IPA multiplex.
* import various generic IPA related functions from libosmo-abisHarald Welte2014-08-201-0/+62
| | | | | | | | | libosmo-abis is about forming A-bis interfaces/lines by means of E1 or the IPA multiplex (or possibly other link layers). The IPA multiplex is used in other contexts, such as the Control interface, or the A interface. In that context, it makes sense to have generic IPA related functions in libosmocore.
* TLV: add TLVP_PRES_LEN() definition to check for existance + minimum lengthHarald Welte2014-08-181-0/+3
| | | | | This is an import from osmo-bts where it was introduced in 6b561bb7ba5f10c5fd96542a7e42de2822352a67
