* 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
* use osmo_{htonl,htons,ntohl,ntohs}() functions all over libosmocoreHarald Welte2017-05-151-8/+9

* 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
* gsm0408: Completing GSM 04.08 RR message typesPhilipp2016-10-271-0/+108
| | | | | | | | | | | - Add missing message types to be up to date with the latest specification release (3GPP TS 04.18) - Add value strings to translate RR message type identifiers into human readable strings. (see gsm48_rr_msg_name() in gsm48.h Change-Id: I3ceb070bf4dc8f5a071a5d43c6aa2d4e84c2dec6
* 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. This commit moves rr_cause_name() below rr_cause_names[] as it should be Change-Id: Ie6c03a6ea02c370d8733db5ba2a709610cd70ce7

* 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.
