* libosmogsm: (re)introduce gsm48_push_l3hdr()Vadim Yanitskiy2018-08-051-0/+3
| | | | | | | | | | | | | There was gsm0480_l3hdr_push() declared in a header file, but not exposed in 'libosmogsm.map'. Furthermore, for some reason it was a part of GSM 04.80 API, what is not actually correct. Let's rename this symbol, and properly expose it as a part of the GSM 04.08 API. Also, let's introduce an auxiliary wrapper for messages, where the transaction identifier is required (see GSM 04.07, section 11.2.3.1.2). Change-Id: I8a045efe8335d83fcbe8d43eb180972e3b1d9dda

* GSUP: introduce new messages for SS/USSD payloadsVadim Yanitskiy2018-05-311-0/+1
| | | | | | | | | | | | | | | | | In order to be able to transfer SS/USSD messages via GSUP, this change introduces the following new message types: - OSMO_GSUP_MSGT_PROC_SS_*, and the following new IE: - OSMO_GSUP_SS_INFO_IE which represents an ASN.1 encoded MAP payload coming to/from the mobile station 'as is', without any transcoding.

* GSUP: implement TCAP-like session managementVadim Yanitskiy2018-05-311-0/+2
| | | | | | | | | | | | | | | | | | | | Unlike TCAP/MAP, GSUP is just a transport layer without the dialogue/context. This prevents us from having session based communication, required e.g. for USSD. But we can emulate TCAP dialogue by adding additional IEs, which would allow to relate each message to a particular session. This change introduces the following IEs: - OSMO_GSUP_SESSION_ID_IE, - OSMO_GSUP_SESSION_STATE_IE, which optionally can be used to indicate that the message is related to a session with given ID, and to manage session state, i.e. initiate, continue, and finish.

* osmo-release.sh: Always generate entire commit changelogPau Espin Pedrol2018-05-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Before this commit, for library projects (containing LIBVERSION in some Makefile), the entire commit list was not stored into the changelog, but only a few lines from TODO-RELEASE files. This is a bad approach for several reasons. First, because that file was only aimed at containing API/ABI breaks, and not the full relevant changeset (like bugfixes, new features, etc.). Second, because it relies on every developer making API/ABI changes to remember to store the change in there during commit break time. Let's instead always store the entire commit list in changelog, and let's use TODO-RELEASE only as a list of hints for the maintainer to help him evaluate how LIBVERSION needs to be bumped for each library. Other tools such as osmo-abi-check.git can be used to help with the process of decission too. Let's take the opportunity too to only commit stuff already added to the staging area, as it proved easier to manage from my personal experinece making latest releases.

* gsm0480: copy the raw USSD data, its DCS and lengthVadim Yanitskiy2018-04-041-1/+3
| | | | | | | | | | | | | | | | | | As it was already documented before, the 'ss_request' struct has a rudiment of deprecated 'ussd_request' struct - the 'ussd_text' field. It represents the data either of an INVOKE component, either of a RETURN_RESULT component, encoded as ASCII in case if DCS is 0x0f (i.e. decoded by the code itself), otherwise raw bytes 'as is'. Previously, there was no possibility to distinguish between ASCII and raw bytes with different DCS. Moreover, the payload decoding is not desired in some cases. Let's introduce the new fields, which will carry the raw unmodified payload, its length and DCS (Data Coding Scheme). Change-Id: Ia193d175021e145bb3b131290231f307dbefc64a
* fsm: allow graceful exit on FSM terminationPhilipp Maier2018-02-191-0/+1
| | | | | | | | | | | | | | | | The function _osmo_fsm_inst_term() terminates all child FSMs befor it calls fi->fsm_cleanup(). This prevents the cleanup callback to perform last actions on the child FSMs (e.g. osmo_fsm_inst_unlink_parent()). - Since moving the cleanup callack to the beginning of the function would alter the termination behavior and possibly cause malfunction in already existing implementation that use OSMO fsm, a new optional callback that is called immediately at the beginning of the terminatopn process is added.

* libosmocodec: implement ECU (Error Concealment Unit) for FRPhilipp Maier2018-01-151-0/+1
| | | | | | | | | | | When a bad GSM voice frame is received, it's being replaced by a silence frame. This may cause unpleasant audio effects. This change implements a functionality to craft a replacement frame from the last known good frame. Currently, only FR is supported, support for other codecs may be added latter.

* gb: optionally allow nsip packets only from a specific hostPhilipp Maier2017-10-241-0/+1
| | | | | | | | | | | | | | When listening for nsip connections is enabled, then every remote host may send packets. This is useful for an SGSN that serves multiple PCUs, but contraproductive for a PCU that awaits packets from a single SGSN. Add struct members remote_ip, and remote_port to struct gprs_ns_inst, when set, then the listening end uses connect() to ensure that only the expected host may send packets.

* GSUP, OAP, osmo-gen-vec: fix AUTS length to 14, not 16Neels Hofmeyr2017-02-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS to our osmo_auth_gen_vec_auts() API. According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14 bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2 and AUTS being the V = 14. It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But writing 16 bytes to a GSUP struct is a potential problem when passing in a 14 byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer. The API implies the length, so far to be 16, so passing in a 14 byte buffer to GSUP would require copying to a larger buffer first. Fix this by using a length of 14 for AUTS everywhere instead. This constitues an ABI breakage, we may handle it as a "fix before an official release", otherwise we need a version bump. The OAP protocol document has also been updated, needs an update in the osmo-gsm-manuals as well. Change-Id: If25b173d9ec57ea4c504d860954912b7d82af455

* Revert "Constify ctrl_cmd struct fields where appropriate"Neels Hofmeyr2016-10-201-1/+0
| | | | | | | | | | | | | This reverts commit ed9d6da5df98538adc70aa03cb569eb9505d04b6. The commit is good as such, but it causes many compiler warnings in the OpenBSC build. We want this to be re-applied as soon as we have patches ready that fix the fallout in openbsc.git.

* vty: Add reserved nodes to enum node_typeJacob Erlbeck2015-11-021-0/+1
| | | | | | | | | | | | | Currently every time a node is added to enum node_type, this constitutes an ABI change, since _LAST_OSMOVTY_NODE will get incremented accordingly. In this case, every project that adds new node type based on that value will have to be recompiled. This commit adds 4 spare node type values, which can be replaced one-by-one by new real types until they are exhausted to avoid this kind of ABI change. Sponsored-by: On-Waves ehf

| | | | | | | | | | | | Currently large values for Bmax default MS get sliced since a uint16_t is used as the type of the corresponding parameter of bssgp_tx_fc_bvc. GSM 48.018, 11.3.2 which in turn refers to 11.3.5 specifies a maximum of 6MB (0xffff * 100). This commit changes the type to uint32_t to cover the full value range. Sponsored-by: On-Waves ehf
