This allows us to pass in strings that are 'const', which for the source of a copy should be the normal/regular case anyway. Change-Id: Icee6a5f88babd3a4e30bf0886f0f8d3b865d80ce

2016-07-23gsm_08_58.h: introduce RSL_CHAN_NR_1 constantNeels Hofmeyr1-0/+1
Using the RSL_CHAN_* constants, we sometimes need to add 1 to the chan bits to indicate e.g. the second TCH/H channel. RSL_CHAN_NR_1 marks this lowest channel bit that needs to be added. The name is analogous to RSL_CHAN_NR_MASK. Change-Id: Iea06432039d1cd23cc6b5acec308bb829b596d47

2016-06-27fsm: Introduce default time-out handlingHarald Welte1-1/+3
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

The actual code is from OsmoBTS' tch.c by Harald Welte. Add unit tests, doxygen annotation and extra memory safety check. Those functions are used in several BTS implementations but seems generic enough to be generally useful. Change-Id: I2b1901c4161e8035f059585901dca593b661556d

Add get_value_string_or_null() to return NULL in case the given value is not found in the list of strings, to be able to cleanly fall back to another list of strings. Absorb the lookup loop from get_value_string(). Context: in osmo-bts, I want to look up an RSL message name in rsl_msgt_names and fall back to rsl_ipac_msgt_names if not found, because the IPAC PDCH ACT and DEACT messages are sent in a standard ABIS_RSL_MDISC_DED_CHAN.

We're starting to use GSUP for circuit-switched (CS) plane, so we need to differentiate the two planes somehow from each other.
2016-05-06import gprs_gsup_message.[ch] from openbsc as gsup.[ch]0.9.4Harald Welte3-1/+142
Move those routines from OpenBSC to libosmogsm, so they can be re-used from other programs. I think it was a mistake to add them only inside the openbsc repository in the first place. We need to pay more attention to this in the future.
