* gsm0408: add chreq_type for CHREQ_T_PDCH_ONE_PHASE and CHREQ_T_PDCH_TWO_PHASEAlexander Couzens2016-12-011-0/+2
| | | | | | For BSC-located pcu the BSC must understand the PDCH chan request. Change-Id: Ice44dcaaf798f93af3652a96c567f8e16a6cf784
* Introduce osmo_strlcpy() function so we can stop using strncpy()Harald Welte2016-11-261-0/+2
| | | | | | | | | | | | | | | | I'm aware of the existing criticism on stlrcpy(), but I think it is still better than what we have now: stnrcpy(), sometimes with Coverity warnings and sometimes with a manual setting of the termination byte. The implementation follows the linux kernel strlcpy() which is claimed to be BSD compatible. We could of course link against libbsd on Linux instead, but I think it's reasonably small and simple to provide our own implementation. Future versions of libosmocore could use some autoconf magic and preprocessor macros to use the system-provided strlcpy() if it exists. Change-Id: Ifdc99b0e3b8631f1e771e58acaf9efb00a9cd493

* RSL: Add defines for ericsson systinfo SI13Philipp2016-11-161-0/+4
| | | | | | | | | | | | | | Ericsson uses non standard information element tags when setting up the SI13 system information configuration. This applies to RSL_SYSTEM_INFO_13, which is normally 0x28, instead Ericsson uses RSL_ERIC_SYSTEM_INFO_13, which is set to 0x0C. Furthermore, Ericsson adds a propritary field called BCCH-Mapping, which is tagged as 0xf2 (RSL_IE_ERIC_BCCH_MAPPING) This patch addes these two information element tags in gsm_08_58.h Change-Id: Idc27352e286b9b8bbcbf0b31bdb676c3d13487a9

* bitcomp: Remove the t4 decoding from libosmocoreHolger Hans Peter Freyther2016-11-101-1/+0
| | | | | | | | | | | | As outlined by mail on the 13th of July the tree based approach to decoding in the PCU is faster by order of magnitude. Instead of having a slow implementation in the library and a quick one in the PCU, let's only have a quick one in the PCU and at some point in the future move it to libosmocore. Execute the plan and remove t4_decode. Change-Id: I021424444625a097560d086c217c81eac4a5ee44

* Revert "Constify ctrl_cmd struct fields where appropriate"Neels Hofmeyr2016-10-201-3/+3
| | | | | | | | | | | | | This reverts commit ed9d6da5df98538adc70aa03cb569eb9505d04b6. The commit is good as such, but it causes many compiler warnings in the OpenBSC build. We want this to be re-applied as soon as we have patches ready that fix the fallout in openbsc.git.

* AMR: add function to check speech framesMax2016-09-281-0/+21
| | | | | | | | Add convenience function osmo_amr_is_speech() to check if given AMR frame is speech frame: non-speech frames often require special processing. Change-Id: Ifaab02a2f581acc302b367d34fd2fc28a4d1e2e3
* msgb: add msgb_talloc_ctx_init(), deprecate msgb_set_talloc_ctx()Neels Hofmeyr2016-09-271-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | So far each and every main() scope creates a msgb talloc context and either passes it to msgb_set_talloc_ctx() or sets tall_msgb_ctx directly (by defining it extern first). Remove some code duplication: add one central function that creates the "msgb" talloc context for all. Most users of msgb employ a talloc_named_const(), but osmo-bts uses a talloc_pool() instead. Offer both ways by means of the pool_size argument, and for both ways make sure the context is called "msgb". Suggest that msgb users should move to this new function: deprecate msgb_set_talloc_ctx(). To be able to do so, include core/defs.h in msgb.h. There's a tradeoff between hiding the msgb talloc context behind API that tries to guess all use cases versus avoiding code dup. This patch opts against code dup and boldly assumes that all future use is covered. Also, the new function suggests to not access tall_msgb_ctx directly, which can be considered a style improvement. It seems that not all main scopes that use msgb actually initialize the msgb ctx. As a fallback for these, explicitly initialize tall_msgb_ctx to NULL.

| | | | | | | | | | | 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
