2016-12-12osmo-bts-trx: fix lchan deactivationMax1-2/+4
Use chan_nr for deactivating lchan instead of lchan->nr: chan_nr is the RSL Channel Number IE value, a bitfield aggregation of lchan type bits (cbits) and lchan number (lowest three bits). The error was introduced in 36153239bfd0b633c4d259a9de0a759f41197a2b. Change-Id: I6dd7060422ab9d18743c1ff2ab419e3e7299d74d

2016-12-08DTX: add explicit check if DTX enabledMax1-0/+3
Check explicitly if DTX is enabled for AMR before checking if SID frame repetition is optional. Change-Id: I660688d56505798cade1495c30338fd6806a3259 Related: OS#1801
2016-12-05TRX: prevent segfault upon phy initMax2-7/+13
Previously if multiply phy instances were configured but not used osmo-bts-trx would segfault. Terminate with clear error message instead so user can correct configuration. Example configuration which caused problem: ... phy 0 instance 0 instance 1 ... trx 0 phy 0 instance 0 Note the 2nd instance of phy 0 which is not used in trx later on.

2016-12-01Fix AGCH/PCH proportional allocationMax10-50/+44
Do not assume that 1 == BS_AG_BLKS_RES but take that information from SI3. Note: due to current implementation quirks we activate channels before SI3 obtained, than we deactivate channels upon receiving SI3 and activate them again. This might not be necessary once we migrate to proper OML state machines. This affects lc15 and sysmo hw. Change-Id: I11377b12680ac3b2f77f80e742b6f0af63fc9c1e Related: OS#1575
2016-12-01cosmetic: vty prompts: add space after '#'Neels Hofmeyr1-4/+4
Typically, our VTY prompts have space after the '#', but some of the osmo-bts VTY prompts don't: OsmoBTS# configure terminal OsmoBTS(config)# bts 0 OsmoBTS(bts)#gsmtap-sapi ccch Add spaces after the '#' to yield e.g. OsmoBTS(bts)# gsmtap-sapi ccch Change-Id: If0591a359e77f01abb76c4113181af7a7733ddd4

2016-12-01DTX DL AMR: rewrite FSM recursionMax8-137/+270
Add explicit state for recursion (sending the different payload data in response to the RTS request for same FN) and corresponding transition. Remove ST_FACCH_V as with new explicit recursion handling it becomes unreacheable. This makes it easier to maintain preemption (interruption of current procedure due to FACCH or Inhibition). This also reduces the number of possible transitions out of each state thus reducing graph's cyclomatic complexity. Change-Id: If39b68083d23a4a35f468a5d75f54eb733ebfd14
2016-12-01trx: Add "maxdlynb" VTY command to control max TA for Normal Bursts.Alexander Chemeris5-1/+68
Originally `maxdly` command in osmo-trx was contrlling max TA for Normal Bursts. This was not a proper behaviour, because it was used to "control maximum distance a handset can attach from" which is controlled by Access Bursts max TA. Osmo-trx was corrected to apply `maxdly` to Access Bursts and a new command was introduced to contrl max TA for Normal Bursts - `maxdlynb`. This patch adds support for this configuration command into osmo-bts-trx. If you wonder why would you need that - some test equipment (namely R&S CMD57) has really bad timing sync and can generate signal a few symbols off. That prevents osmo-trx from properly receiving otherwise perfectly good bursts generated by CMD57. This configuration is a solution for this. Change-Id: Ib5d255299668ac1ef9f0ce95e016f55ba3c82277

2016-11-27octphy: multi-trx support: fix AC_CHECK orderPhilipp1-1/+1
The header file octphy/octvc1/gsm/octvc1_gsm_default.h is not visible to the configure script when the octphy header files are referenced via --with-octsdr-2g instead having them installed in /usr/local/include. This results in a failed AC_CHECK_MEMBER check for tOCTVC1_GSM_TRX_CONFIG.usCentreArfcn, even if header files with multi-trx support are used. The configure.ac script manipulates the CPPFLAGS in order to make the octphy include files visible to AC_CHECK_ and restores the original CPPFLAGS when done. This is required when --with-octsdr-2g is used. AC_CHECK_MEMBER is executed before the CPPFLAGS are manipulated. This causes no issues if the headers are properly installed to /usr/local/include, but does not work when --with-octsdr-2g is used. This commit moves the AC_CHECK_MEMBER command into the section where the manipulated CPPFLAGS are valid in order to fix the problem described above See also commit: f5494e84e898f947190466d30d5f932bac0fadf9 Change-Id: I7bdfa4449cd6061c395cce315b372c2833520e37

2016-11-16vty: Add commands to manually activate/deactivate a channel.Alexander Chemeris1-0/+60
This is the easiest way I found to make BTS level loopback to work. Another way to implement this is to have BSC/NITB to send the OML command, but it's a longer path with no clear benefits. Note, that the current code hardcodes the channel to be TCH/F with v1 speech, which is what we need for the basic BER testing. We may want to extend this later to support more channel types.

2016-11-14l1sap: Fix use-after-free in loopback mode.Alexander Chemeris1-0/+3
By default l1sap_tch_ind() returns 0 which signals to its caller that message has been processed and can be freed. In case of loopback we're forwarding the message to dl_tch_queue who will free it later. Returning 1 from l1sap_tch_ind() prevents caller from freeing message.

2016-10-28DTX DL: split ONSET state handlingMax7-35/+120
Handle ONSET cause by Voice and FACCH separately. In case of Voice we have RTP payload which we have to cache and send later on in next response to L1 RTS. FACCH have higher priority so it preempts both voice and silence alike - hence we can send ONSET immediately but still have to track previous state in order to get back to it gracefully. This affects lc15 and sysmo hw as there's no FSM-based DTX implementation for other models yet. Note: this requires patch for OpenBSC which adds FACCH buffer to tch.dtx struct.
