* fsm: Introduce default time-out handlingHarald Welte2016-06-272-9/+16
| | | | | | | | | | | If a FSM doesn't specify any timer_cb, simply terminate the FSM by default on time-out. This is a reasonable default for most cases, and avoids copy+pasting a one-line timer_cb function in every FSM. Also, even if there is a timer_cb, let it have a return value to decide if the core should terminate after return from timer_cb or not. Change-Id: I0461a9593bfb729c82b7d1d1cf9f30b1079d0212

* 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.
