* ports.h: Add VTY port for GGSNHarald Welte2017-08-161-0/+2
| | | | Change-Id: I5bd49fbc19e88db96b4adbd56c82e7936059551c
* add osmo_fd_setup() convenience function to fill-in osmo_fdHarald Welte2017-08-121-0/+4
| | | | | | | | This basically follows the concept of osmo_timer_setup() and allows the caller to fill-in all configurable fields of osmo_fd in one line of code, rather than open-coding it in 5 lines everywhere. Change-Id: I6dbf19ea22fd65302bfc5424c10418d1b7939094
* tlv: add [msgb_]t16lv_put() for 16bit tag + 8 bit len TLVsHarald Welte2017-08-091-1/+20
| | | | | | | | | | | In the Protocol Configuration Options IE (see 3GPP TS 24.008 10.5.6.3) there is yet another new TLV format (derived from PPP IPCP/LCP/...) which uses 16bit tag and 8bit length. Let's add functions so we can generate related TLVs. Parsing is unfortunately not possible in our existing structure as our tlv_parsed array only has 256 entries and thus cannot cope with 16bit tags.

* Add osmo_gprs_{ul,dl}_block_size_{bits,bytes} functionsHarald Welte2017-08-091-0/+25
| | | | | | Those functions can be used to look up the size of (E)GPRS blocks. Change-Id: I05ff75ef7dfae639886bbd09fe35f03a8af9d988
* Rename GSMTAP_CHANNEL_PDCH to GSMTAP_CHANNEL_PDTCHHarald Welte2017-07-291-1/+3
| | | | | | | PDCH is the physical channel, while actually we want to talk about PDTCH the logical channel. Introduce backwards compatibility define. Change-Id: Id6782d2247846e2db29fc58d98684970a66db948
* BSSGP: add function to reset all PTP BVCMax2017-07-281-1/+1

* add DLMGCP logging category for libosmo-mgcpNeels Hofmeyr2017-07-181-1/+2
| | | | | | | In the course of splitting up the openbsc.git repository, we will create libosmo-mgcp and need a library logging category for that purpose. Change-Id: I09c587e2d59472cbde852d467d457254746d9e67
* extend osmo_sysinfo_type with missing SYSINFO_TYPEHarald Welte2017-07-151-1/+6

* socket: Add new OSMO_SOCK_F_NO_MCAST_ALL optionHarald Welte2017-07-131-0/+2
| | | | | | | Using this option at socket creation, the caller can request disabling the IP_MULTICAST_ALL socket option. Change-Id: I5ab5de45c0b64ceb3636ea98245a23defa24ffd4
* socket: Allow disabling multicast loop on socket creationHarald Welte2017-07-131-0/+2
| | | | | | | | | | | This introduces a new flag OSMO_SOCK_F_NO_MCAST_LOOP, which can be used to disable the looping back of multicast packets transmitted throug this socket to other local sockets on the machine. As this looping-back is active by default, a single option to deviate from the default is deemed sufficient. Change-Id: I24a5b1ebc3f84d2d5d4734e54df50efaea26490b

* select: Add new osmo_fd_close() functionHarald Welte2017-07-131-0/+1
| | | | | | | | | This is a convenience helper that will both close a fd, mark it as closed and unregister it from the event loop abstraction. In most cases, you probably actually want to use it instead of manually closing and calling osmo_fd_unregister(). Change-Id: Icd0933eed6a24edde7cdcb378e138897ecc5332c

* Add pseudo-random bit sequence generator to libosmcooreHarald Welte2017-07-102-0/+26
| | | | | | | These PRBS sequences are specified in ITU-T O.150. They are typically used as test data to be transmitted for BER (bit error rate) testing. Change-Id: I227b6a6e86a251460ecb816afa9a7439d5fb94d1

* gsm_04_08/sgsn: Add another IE for internal usage in the sgsnHolger Hans Peter Freyther2017-07-091-0/+1
| | | | | | | | | The PDP charging characteristics will be returned from the PDP selection code and be used in the SGSN. It is following the same approach as the QoS and PDP addr. It is a bit of a pity that we have to define this in a different project. Change-Id: I7815c5dfd7b7fb0ea78d816ebfb3abfbf0090afe
* Deprecate wrappers around loglevel_strsMax2017-07-081-2/+2
| | | | | | | | Add deprecation notice for public API use: it shouldn't be used outside of libosmocore anyway. Change-Id: I792e30dc44f027fd94e1f65af19fe08bac52b95c Related: OS#71
* gsup: Add encoding/decoding for the pdp charging characteristicsHolger Hans Peter Freyther2017-07-071-0/+8
| | | | | | | | These fields can be in the ISD and the PDP Context inofmration. Store pointers to this IE in both cases. It needs to be used by the SGSN when opening a PDP context. Change-Id: Iedc7c02adcf77ca5c9545119e19c968dfbbb3e6b
* Add missing BSSGP cause valuesMax2017-07-011-20/+57
| | | | | | Add values from 3GPP TS 48.018 Change-Id: Ie39a6c91a46d179392d861805a106743a07c6fb0
* l1sap.h: Add ber10k and lqual_cb to ph_tch_paramPau Espin Pedrol2017-06-301-0/+2
| | | | | | | These fields are required in osmo-bts to do low link quality checks in a generic way. Change-Id: If4ae20c22b881e94585dad710f17b9e37f77bf82
* fix map entry and .h declaration for gsm0808_chan_type_to_speech_codec()Neels Hofmeyr2017-06-231-1/+1
| | | | | | | | | | | | Recent commit 3149b0d076477303a38df735fe579b1b06ee17b2 adds function gsm0808_chan_type_to_speech_codec() but adds a completely mismatching name in libosmogsm.map, as well as a definition with a typo in the name. Fix the entry in libosmogsm.map. Add the missing 'c' in gsm0808_utils.h Change-Id: I5a621fa5ef6b632eabbe224f3dd383eacaffb695
* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-23119-309/+335
| | | | | | | | | | | | | | | | | Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec). Change-Id: Ifa70e77e90462b5eb2b0457c70fd25275910c72b
* doxygen: various fixes in core/timer.hNeels Hofmeyr2017-06-231-19/+16
| | | | | | | | | | | | Move a longish comment to the timer group so that it appears in the API doc. Un-doxygen some floating comments that were associated with unrelated code items ('/**' --> '/*'). Add braces to some function names so that the API doc will render as reference links. Change-Id: I3ea5b88cbe9cb54702429158bf47e768e04e8fe7
* api doc typo fix in core/logging.hNeels Hofmeyr2017-06-231-1/+1
| | | | Change-Id: I3f1cd5b10e7beccb61f370d7f8fa2666e56542cf
* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-2359-885/+885
| | | | | | | | | | Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
* cosmetic: remove API documentation strings in header filePhilipp Maier2017-06-221-24/+0
| | | | | | | | | | | | Typically we don't place comments with the function declarations in .h files. Not sure why this file has comments for each. The API doc belongs in the .c file as proper doxygen comments, and shouldn't be duplicated in the .h file. In this particular case, doxygen comments are added in the corresponding c file recently.

* gsm0808: add function gsm0808_speech_codec_from_chan_type()Philipp Maier2017-06-221-0/+2
| | | | | | | | | | | | | | | | The contents of the speech codec element (struct gsm0808_speech_codec), that is also used in the speech codec list element (struct gsm0808_speech_codec_list) can be generated directly from the permitted speech parameter in the channel type field (struct gsm0808_channel_type) when full AoIP with compressed speech via RTP/UDP/IP is assumed and when the codec configuration on the air interface exactly matches the codec configuration on the IP backhaul. This patch adds a function that can be used as a helper to fill out spech codec fields by only giving a permitted speech parameter as input. Change-Id: I257c972e9fdf0dfe940a8d483447085bd62e50a2
* gsm0808: add function gsm0808_chan_type_to_speech_code()Philipp Maier2017-06-221-0/+2
| | | | | | | | | | | | The permitted speech field used in channel type element (struct gsm0808_channel_type) uses a different representation as the type field in the speech codec element (struct gsm0808_speech_codec) This patch adds a function to convert from permitted speech to speech codec type. Change-Id: Ib26a9c20864459b2baaa04f49b6e7902ba44b7cb
* gsm0808: add default speech codec configurationPhilipp Maier2017-06-221-0/+21
| | | | | | | | | In an AoIP scenario, the speech codec list field specifies the codecs used in the RTP interface. This patch adds a table with default codec configurations that match the codec configurations that are also used on the air interface. Change-Id: I9dc0165d76a022b2c1b7418bc3133407e61b7261
* gsm0808: fix AoIP speech codec element parser/generatorPhilipp Maier2017-06-221-2/+0
| | | | | | | | | | The implementation of the parser/generator for the speech codec information element slightly wrong, making it impossible to use it properly. (See also: 3GPP TS 48.008, 3.2.2.103) Change-Id: Idabb0f9620659557672e1c6b90c75481192e5c89
* gsm0808: add speech codec type constantsPhilipp Maier2017-06-211-0/+18
| | | | | | | | The codec type to be set in member type in struct gsm0808_speech_codec has its own coding scheme to reference the used codec types. This patch declares an enum with valid speech codec types. Change-Id: Icaa768071d4364e671bc7e6d48b82d1f07f93f93
* cosmetic: Add info about coresponding codecs to permitted speech constsPhilipp Maier2017-06-211-7/+8
| | | | | | | The constants in enum gsm0808_permitted_speech are not very expressive. Add comments indicating each constant's corresponding codec. Change-Id: I9734f7c261becffe38ffd41c304d006d08530c1a
* gsm0408: update bearer capability speech versionPhilipp Maier2017-06-211-1/+6
| | | | | | | | 3GPP TS 24.008 specifies two new speech versions for half rate and two new speech modes for full rate. This patch adds the relevant constants to enum gsm48_bcap_speech_ver in gsm_04_08.h Change-Id: Id2835384c855f924332d38f01c73bd1cfdb62549
* cosmetic: Add codec references to Speech Version IndicationPhilipp Maier2017-06-211-6/+6
| | | | | | | Add the information which GSM Speech codec version coresponds to which bearer capability speech version. Change-Id: Ic9493fea139420a52c32b17d00ac7d0b2bf86967
* vty: additional nodes for sccp-address configurationPhilipp Maier2017-06-211-2/+2
| | | | | | | | | | The planned sccp-addressbook implementation in libosmo-sccp requires two additional VTY nodes. See also in libosmo-sccp.git: Change-Id I068ed7f7d113dab88424a9d47bab7fc703bb7942 Change-Id: I42aa29c0cccc97f284b85801c5329b015b189640
* Move NUM_BYTES macro to core libraryMax2017-06-192-1/+2
| | | | | | | | | It's universally useful so it make sense to have it in the shared core: * move macro from libosmocoding to libosmocore * add OSMO_ prefix * add doxygen docs Change-Id: I5386ba3e1f1cc153ba96c29dc71c9075a052aa02
* Fix compilation warning on deprecated macroPau Espin Pedrol2017-06-182-2/+8
| | | | | | | | | A warning was printed even if the deprecation didn't apply to libosmocore because it is still allowed to use it internally. This patch fixes this case while still printing a warning if external projects build using libosmocore headers. Change-Id: I32212f20756f828af1017482a71e29e4b3adbad4
* update/extend doxygen documentationHarald Welte2017-06-121-7/+1
| | | | | | | | | It's a pity that even with this patch we still are fare away from having the whole API documented. However, at least we have a more solid foundation. Updates not only extend the documentation, but also make sure it is rendered properly in the doxygen HTML. Change-Id: I1344bd1a6869fb00de7c1899a8db93bba9bafce3
* gsm0503_interleaving: Mark input arguments as 'const *'Harald Welte2017-06-121-5/+5
| | | | | | | The interleaving/deinterleaving functions were missing 'const' qualifiers on their input data buffers Change-Id: I2118c34a6353167787b23f877f1d81d60151aaf9
* Add doxygen documentation to libosmocodingHarald Welte2017-06-125-0/+50
| | | | | | | This adds the minimum amount of API documentation that we should have on all our code, particularly new code merged into a library. Change-Id: I526804f64313867913574e50e5b9e9205ad3aa74
* gsm0503_{coding,mapping}: Mark input arguments as 'const'Harald Welte2017-06-122-21/+21
| | | | | | | | It is generally our coding style to mark pointers to constant input data as 'const *'. For some reason the gsm0503 coding and mapping was not adhering to this, so let's bring it into compliance. Change-Id: Id8731d7ae6171dff94741b6ddbb95ab5f03bfd4e
