2010-03-25	lchan: Change transaction to work on the GSM Subscriber Connection	Holger Hans Peter Freyther	1	-3/+3
	Change the MSC transaction code to operate on a GSM Subscriber Connection instead of the lchan. This will help us to separate the two commands properly.
2010-02-20	split 'libosmocore' from openbsc codebase	Harald Welte	1	-1/+1
	This library is intended to collect all generic/common funcitionality of all Osmocom.org projects, including OpenBSC but also OsmocomBB The library currently includes the following modules: bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer, tlv_parse, linuxlist msgb allocation error debugging had to be temporarily disabled as it depends on 'debug.c' functionality which at the moment remains in OpenBSC
2009-12-20	Introduce new MNCC based proxy mode	Harald Welte	1	-4/+59
	Since the MNCC API can now send and receive frames to/from the MNCC application, we can also implement a proxy this way. Not at the RTP/UDP packet level, but at the 'TCH speech frame' level. Especially for handover, we need this mode as the receiver in the BTS needs a persistent SSRC and monotonic frame numbers / timestamps.
2009-12-19	Add RTP support for EFR	Harald Welte	1	-1/+1
	This is just the minimal support to receive and send EFR codec RTP frames. We are missing the code to convert TRAU frames in EFR format!
2009-12-17	logging: introduce log levels at caller site	Harald Welte	1	-7/+6
	This introduces a new LOGP() macro together with LOGL_* definition to support multiple log levels (severities) throughout the codebase. Please note that the actual logging system does not use them yet, in this patch we simply introduce the new macros at the caller site.
2009-12-12	Gracefully reject non-speech calls	Harald Welte	1	-5/+28
	As we currently really only deal with voice/speech calls and don't support FAX and DATA (CSD) calls, we now gracefully reject them.
2009-08-15	move talloc context creation out of on_dso / constructors	Harald Welte (local)	1	-6/+1
	the various constructors get called in a non-obvious, linker determined order, which makes certain objects disappear from the talloc report. This change moves the talloc context creation into a new talloc_ctx.c file
2009-07-28	move allocation of talloc contexts into link-time constructor	Harald Welte	1	-6/+5
	This is much more optimal than checking if the context exists every time we allocate the respective object.
2009-06-26	zero-initialize some more memory that we allocate	Harald Welte	1	-1/+1

2009-06-20	introduce talloc all over OpenBSC	Harald Welte	1	-3/+13

2009-06-11	use less magic numbers (04.08 CC cause values)	Harald Welte	1	-5/+10
	Introduce a gsm48_cc_cause enum and use it from gsm_04_08 and MNCC, also make sure we use gsm48_cause_loc rather than plain numbers.
2009-06-10	reworked MNCC codebase	Harald Welte	1	-0/+382
	This is Harald's reworked MNCC base, slowly heading towards integration into master. The key changes are: * provide much more structure to the data in gsm_mncc * encode_* and decode_* functions now take a structure rather than tons of individual arguments (whose order nobody can remember) * make sure we don't have copies of the same code everywhere by introducing mncc_set_cause() and mncc_release_ind() * save horizontal screen space if possible * make sure we break lines > 80 characters
