* Add function to properly encode RAIMax2018-01-081-20/+21
| | | | | | | | | | | | | Add gsm48_encode_ra() which takes appropriate struct as [out] parameter instead of generic buffer. Using uint8_t buffer instead of proper struct type prooved to be error-prone - see Coverity CID57877, CID57876. Old gsm48_construct_ra() is made into tiny wrapper around new function. The test output is adjusted because of the change in function return value which was constant and hence ignored anyway. Related: OS#1640 Change-Id: I31f9605277f4945f207c2c44ff82e62399f8db74

* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-231-3/+4
| | | | | | | | | | | | | | | | | 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).

* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-231-25/+25
| | | | | | | | | | 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

* update/extend doxygen documentationHarald Welte2017-06-121-10/+70
| | | | | | | | | 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

* add gsm48_pdisc_msgtype_name()Neels Hofmeyr2017-03-161-0/+198
| | | | | | | | | | | | | | | Composing the message type string requires knowing the protocol discriminator. To ease printing the message type, add this function to switch between the defined value_string[]s depending on pdisc. Also publish the message type value_string[]s -- without inline functions to access them because it is anyway more convenient to use gsm48_pdisc_msgtype_name() instead. Since gsm48_pdisc_msgtype_name() is nontrivial, do not add as inline function -- in case the message type is not known, it needs a static string buffer.

* add gsm48_pdisc_names and gsm48_pdisc_name()Neels Hofmeyr2017-03-161-0/+19
| | | | | | | I often want to log the protocol discriminator in the openbsc debug log. It's more useful to get the name directly instead of looking it up every time. Change-Id: I0f053e2a4360b27ffccda7cf82469fb1b1cbb3ae

* COSMETIC: moving rr_cause_name() in gsm48.cPhilipp2016-10-271-5/+5
| | | | | | | | | | rr_cause_name() is located a far of from value_string rr_cause_names[] while other value string functions are located right below their related value string definitions.

* Revert "gsm48: move to hex TMSI representation"Holger Freyther2016-05-201-1/+2
| | | | | | | | | | | | | | | | | This is a "flag" day change. Old OpenBSC break with new libosmocore because suddenly there is the 0x in front. I am afraid we need to find a better solution here. I think we will need to create a gsm48_mi_to_string variant that takes a mode parameter to enable the TMSI mode and deprecate the old method. Right now we should not break old versions of OpenBSC. This reverts commit 78ad042f94afd5bf7de477ae634e9d2fdd9c9dc4.

* gsm48: move to hex TMSI representationVadim Yanitskiy2016-05-201-2/+1
| | | | | | | | | | | | | Previously, we traditionally displayed a TMSI in its integer representation, which is quite unusual in the telecom world. A TMSI is normally printed as a series of 8 hex digits.

* gsm48: factor out MCC+MNC BCD parsing for re-use in UMTSNeels Hofmeyr2016-03-151-21/+34
| | | | | | | | | | 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.
