2019-03-27OC-2G: Fix TA adjustmentMinh-Quang Nguyen1-2/+2
Problem: TA provided from L1 PH-DATA-IND is a relative amount of TA adjustment to actual TA being used for given TBF. The current TA update algorithm in PCU simply applies the relative amount of TA to given TBF but does not take into account of current TA. As a result, the PCU will request wrong TA jump for given TBF if the MS is moving away from BTS more than 2 km. Related issue: http://osmocom.org/issues/2611 Fixes: - The PCU needs increase or decrease current TA of given TBF on receiving of relative amount of TA adjustment provided by PH-DATA-IND from L1. - The PCU needs to set absolute TA of given TBF on receiving absolute TA provided by PH-RA-IND from L1.

2019-03-27Update IA Rest Octets encodingMax1-17/+13
Write initial bits of 3GPP TS 44.018 §10.5.2.16 IA Rest Octets the same way as write_ia_rest_*() routines do. This should also fix the issue addressed in I75dd5bebc74eea85edf9582607c774d0bba0d2a6 initially by properly encoding L/H bits. Change-Id: I7ed5270bf95c3f6e9e026ff447eef8539f6f0314

2019-03-27Use Timing Advance Index in UL assignmentsMax3-12/+12
Write TAI (if available) when generating Rest Octets for UL Assignment. This should not affect actual PCU behavior because TAI is not yet supported by upper layers but we have to adjust corresponding tests anyway. That's updated version of reverted commit. Change-Id: I69407793bdb863be5fc42adadf75842d22f27335 Related: OS#3014
2019-03-27Rewrite Packet Uplink IA Rest Octets for SBAMax3-17/+24
Use bitvec_set_*() directly without external write pointer tracking to simplify the code. This is part of IA Rest Octets (3GPP TS 44.018 §10.5.2.16) which is the last part of the message so it should not interfere with the rest of encoding functions. The difference in the expected test output is due to proper handling of TAI which should not be transmitted for SBA according to the Note in Table 10.5.2.16.1 in 3GPP TS 44.018. The change was manually tested against real mobile phone using options 'gprs mode gprs' in osmo-bsc.cfg and 'two-phase-access' in osmo-pcu.cfg to make sure appropriate code path is actually triggered. That's partially based on reverted commit 93d947f5e8a30acc9250c124bf9d5bb6a8863526. Change-Id: I97d53c27c1ca9e032d431b3aa7f915027d63ddc0 Related: OS#3014

2019-03-27Fix Channel Coding Command for MCSMax4-12/+12
Previously result of ".to_num() - 1" was used without any checks which means that in case of to_num() returning zero we would effectively try to encode (uint8_t)(-1). Let's fix this by using proper mcs_chan_code() function which returns Channel Coding Command for MCS without the need to further correct it and adjust expected tests output accordingly. Change-Id: I868062a81fffe6714a811c032215f25a79259905
2019-03-27MCS: add Channel Coding Command encoderMax7-20/+31
Add function to encode MCS value as proper EDGE or GPRS Channel Coding value according to 3GPP TS 44.060 and corresponding helpers. Use it for everything except IA Rest Octet encoding which is done in a follow-up patches to make sure that we distinguish between encoding-related changes to test output and unrelated changes.

2019-03-27gprs_debug: Use named initializers and explicit array indiciesHarald Welte1-14/+99
This is a much safe way, it allows for modifications of the debug subsystem enum member values without breakage. Also, the syntax introduced here is what we do in all other Osmocom CNI projects. Change-Id: I2be88586ca44b0b8361f96cf3c034c8459244c2c
2019-03-27Forward GPRS SUSPEND REQ from BTS to SGSN using BSSGPHarald Welte2-0/+28
As specified in 3GPP TS 03.60 Section 16.2.1 and 44.018 Section 3.4.15, a Class B MS is sending a "RR GPRS SUSPEND REQ" via a DCCH to the BTS if it wants to suspend GPRS services. As of Change-Id I3c1af662c8f0d3d22da200638480f6ef05c3ed1f, OsmoBTS forwards this via the PCU socket, so we need to pick it up and send it via BSSGP to the SGSN. Change-Id: I7b4beb413a6f974373a404b5a11c44d86ba695d3 Closes: OS#2249
2019-03-27pcu_l1_if: Fix erroneous endian-swapping of the CellIDHarald Welte1-3/+2
In Change-Id I787fed84a7b613158a5618dd5cffafe4e4927234 in February 2018 we accidentially introduced a change that would erroneously swap the endianness of the CellID on the way between PCUIF socket and BSGSP. This meant that all OsmoPCU based BTSs would report the wrong CellId to the SGSN. Closes: OS#3854 Change-Id: I2f6cc930c5dbf8dac386b24b0756df2efe8199e4
2019-03-26MCS: add mcs_is_*() helpersMax12-45/+65
In preparation for Channel Coding Command encoder in follow-up patches let's add necessary helpers. Those are similar to previously used helpers from GprsCodingScheme class but without CamelCase and with less typo chances between Gprs and Egprs cases.

2019-03-24MCS: move Mode enum outside of class definitionMax9-51/+50
Move Mode (EDGE/GPRS) definition and related functions outside of GprsCodingScheme class. This allows us to use standard libosmocore value_string functions. Change-Id: I3baaac7f1ca3f5b88917a23c1679d63847455f47
2019-03-19Fix TA index encoderMax1-6/+6
The TAI is described as { 0 | 1 < TIMING_ADVANCE_INDEX : bit (4) > } in 3GPP TS 44.018 §10.5.2.16.1 so it should be encoded with if-else. Change-Id: I54482790e1cf3cb13a635a99a481250576deabaf

2019-03-19MCS: move HeaderType enum outside of class definitionMax12-92/+126
Move functions which compute number of blocks or bits depending on header type and corresponding enum outside of GprsCodingScheme class. This will allows us to use standard libosmocore value_sting functions in upcoming patches for IA Rest Octet encoding/decoding. Change-Id: Id0873f85e1f16a72e17e7fbc4ad76b194917067f
2019-03-19Explicitly clean up BTS singletonMax3-3/+22
Add method to explicitly cleanup BTS singleton similar to GprsMsStorage class and use it from main(). The destructor becomes trivial wrapper around cleanup() method. This prevents annoying SIGABRT on exit of OsmoPCU caused by rate_ctr_group_free() being called after talloc_free() which removes the context in which counter group is allocated.

2019-03-19MS store: move test helper to unit testMax3-20/+18
It's confusing to have test-specific helper with the same name as tested function directly inside the GprsMsStorage class. Let's convert it into static function and move to the unit test. Change-Id: Ia2a5b90779051af894fe15d957c1d26f0a142f33
2019-03-19tests: use -no-install libtool flag to avoid ./lt-* scriptsOliver Smith1-1/+1
This ensures that the rpath of the generated binaries is set to use only the just-compiled so-files and not any system-wide installed libraries while avoiding the ugly shell script wrapper. Change-Id: I2915f0de87598f9f23efc2b9a8f4a6bdf4966efb
2019-03-14Use unique NSEI/BVCI/NSVCI in TBF testsMax2-14/+5
This works around the issue with colliding rate counter group index highlighted by 86e35e488740889f8ad03d09a78918839b883240 by using different NSEI/BVCI/NSVCI parameters for different TBF tests. Change-Id: Id7d2d1a48308a6b1fb17768aee0e79adbdee56ee Related: OS#3827

2019-03-07Log (M)CS UL update errorsMax2-2/+30
Previously some of the errors in update_cs_ul() call were silently ignored. Let's log all those as errors with appropriate message. Note: test output needs updating because we do not (yet) set proper meas struct in TBF tests. That's likely wrong but it's better to update tests in a separate commit. Change-Id: I4084fb281dd9dad04a2a3a68cac2a8f7b462548e
2019-03-07Enable LGLOBAL logging for TBF testsMax2-1/+5

2019-03-06Tighten lqual table limits checkMax3-9/+13
Previously MAX_GPRS_CS was used for both EDGE and GPRS which means that we waste extra memory in GPRS case. It also leads to misleading name. Let's fix this by introducing separate definitions for GPRS and EDGE cases and use them as appropriate in limit checks. Change-Id: I3ae1ee64ec8e80247b8fe669cc79505b4dadf58f

2019-03-05EDGE tests: remove no-op checkMax2-8/+0
The headerTypeControl() function always return constant and is only used inside OSMO_ASSERT() which compares it to the very same constant which makes it no-op. Let's remove this clutter. Change-Id: Ie0f81fe05a2b3f432de7d1f3446e8115d7524ff4
