2017-06-24l1sap: if lchan is in loopback, don't accept incoming RTPHarald Welte1-0/+5
When the lchan is in loopback mode, we loop back all uplink blocks into downlink blocks. We do not processs any RTP frames for that lchan anymore. Rather, we discard those RTP frames to avoid mixing looped-back samples with those received from remote. Change-Id: I29ef4963e9c491c94c413cbc10436a2388c04d9b

2017-06-24measurement: Remove dead codeHarald Welte2-39/+0
We used to have trx_meas_check_compute() and call that from the bts-specific code in order to iterate over all timeslots and all lchans in the timeslots if we have to send measurement reports. This was executed once per frame, and created unequal CPU load over time, which in turn might increase different per-ts jitter. Since 2f028c4e2c29f63df9926435466aa35377947767 in April 2017 we have lchan_meas_check_compute(), which performs this on a per-lchan basis, and hence CPU load is distributed over all active timeslots.

2017-06-24Revert "RSL: receive and send multiple SI2q messages"Neels Hofmeyr2-49/+28
This reverts commit 340cff51f49f6e798cb5fb6d1b9febdd09902906. osmo-gsm-tester detected a regression due to this commit, when running osmo-bts-trx. The modems timed out when waiting for them to register with the osmo-bts-trx network. osmo-bts-sysmo is apparently not affected. No further details on the failure cause are known yet. The failure is shown for example by http://jenkins.osmocom.org/jenkins/view/osmo-gsm-tester/job/osmo-gsm-tester_run/868/ Change-Id: I15bca30ddc09a7a3044096626016f6130d07636c

2017-06-18OML Add osmocom-specific way to deactivate radio link timeoutHarald Welte3-6/+22
In some situations (e.g. when trying to do measurements/testing on the BTS receiver / uplink) it is useful to have a way to disable the radio link timeout and keep any channel open until deactivated, irrespective of whether (valid) data is received or not. This adds a related feature that can be activated by using an osmocom-specific value of 0xff for the TS 12.21 Connection Failure Criterion (9.4.14).

The higher layers relay on a normalized version of frame number in order to detect the end of a measurement period.

2017-06-02Revert "Add version to phy_instance"Neels Hofmeyr3-8/+3
This reverts commit 9eeb0b1a136fc8c24a86cb4d832c264674c10db0. This commit caused osmo-gsm-tester test runs for the sysmoBTS to fail with SIGABRT consistently. See below redmine issues. In osmo-bts-sysmo/l1_if.c, it uses talloc_asprintf to write to the char version[MAX_VERSION_LENGTH]; talloc_asprintf() however is intended to work on string buffers allocated by talloc, and attempts to reallocate version[]. Furthermore, it is not clear why the patch passes a 'data' arg to app_info_sys_compl_cb() that is not used. Hence I will revert this instead of trying to fix. Please resolve issues and re-submit.

2017-05-29sysmobts: Re-order the bit-endianness of every HR codec parameterHarald Welte3-6/+57
The so-called "RTP mode" of the DSP contains a bug on all firmware versions < 5.3.3 which causes the bit-order within each of the non-aligned codec parameters to be wrong. Introduce a function originally written by Sylvain Munaut during 32C3 in http://git.osmocom.org/openbsc/commit/?h=sylvain/32c3_codec&id=5b4a16bbe93a7b1ace65cc23d6cce56ecf4f1275 to bring the bits into [the correct] order. This has never been seen in a "pure sysmoBTS" setup, as all BTSs would use the same (wrong) bit-ordering and thus interoperate. This patch now checks for an affected DSP firmware version and then jumbles (old DSP firmware version) or does nothing (new DSP firmware version).

2017-05-29vty: Remove command for manual channel activation/deactivationHarald Welte1-60/+0
OsmoBTS won't run without being connected to a BSC. The BTS wouldn't start to transmit if the BSC doesn't properly initialize it. So if we want to activate some channels manually for testing, we should do so from the BSC, and not inside the BTS code. Doing this in the BTS means that the BSC is not aware of it and might want to use that channel for something else meanwhile. Osmo{BSC,NITB} has gained ability to manually activate a channel from the VTY in Change-Id I44fc3904678eb48bd3ab1a3da8c0c265fa082e0d as can be seen at https://gerrit.osmocom.org/2759 So let's remove the old/obsoleted code here.

For some reason, osmo-bts-trx did another take at parsing NM_ATT_CONN_FAIL_CRIT and storing the second octet in btsb->radio_link_timeout, just like the generic code already does in oml_rx_set_bts_attr(), but without proper checking and any error message.

Make more use of TLVP_PRES_LEN() instead of plain TLVP_PRESENT() and implicitly assuming a certain length of the information element. What this obviously doesn't introduce is some kind of error generation/reporting in case the minimum length is not fulfilled. An IE that's too small is silently ignored by TLVP_PRES_LEN() and treated as if the IE wouldn't exist in the first place. Change-Id: If5c4eee65711c49bc8ba4675221b1d5fd16198e9
2017-05-29osmo-bts-sysmo: Include frame number in MEAS INDPhilipp Maier1-2/+7
l1_if.c does not generate struct osmo_phsap_prim l1sap properly. The (logical) frame number is not included in this struct. This renders the logic that processes the reported measurements non functional, since the logic (see measurement.c) is no longer able to detect the end of the measurement period.
