2018-10-09document why ipa chopped ping fails with control interfaceStefan Sperling1-2/+3
We cannot test the control interface with an IPA ping message. The control interface only supports osmocom-specific extensions, and the IPA ping message is not part of those extensions. Other tests will have to be devised for the control interface. Change-Id: Iae0f16394c78196de621c14b34d1b1905c0cb7c8 Related: OS#2010
2018-10-08Add a TTCN3 module for IPA protocol testingStefan Sperling4-1/+183
This new module allows us to test IPA code in libosmocore and libosmo-netif. Currently only one test is implemented, which sends a chopped IPA ping message and expects to receive an IPA pong. The system under test is any IPA speaker on any TCP port. Any test suite may call parametrized functions to create an IPA testing component and run a particular test. So far, one such test has been added to the BSC_Tests suite. Change-Id: I246a405414e36a44dc1e308692faab8bf04da0e6 Related: OS#2010
2018-10-05MSC_ConnectionHandler: Make sure COMPLETE LAYER 3 INFORMATION contains a ↵Philipp Maier1-2/+24
codecList Since our BSC implementation supports AoIP, the COMPLETE LAYER 3 INFORMATION message must contan a Codec List (BSS Supported) information element. The test currently just receive a L3 compl Template and then continue. This is implemented without an altstep. So lets have an altstep with timeout here and make sure that the codecList information element is always included. However, since AoIP was specified after sccp-lite, we need to make sure that for sccp-lite configurations, the Codec List is not included. - Check L3 compl message using an alt-step - Make sure codecList is always included (for AoIP) Change-Id: Ia16a454e78421430ec32cc37939d429970cb06ec Related: OS#3548
2018-10-05BTS_Tests.ttcn: fix: expect RSL_MEAS_RES messagesVadim Yanitskiy1-0/+4
Since both Calypso PHY and trxcon (since OS#2988 is fixed) are always sending the Measurement Reports in dedicated mode, the test cases should expect to 'see' the RSL_MEAS_RES messages, and ignore them if they are out of the testing scope. This change makes the following test cases pass: - TC_rll_est_ind, - TC_rll_rel_ind_DCCH_0, - TC_rll_rel_ind_DCCH_3, - TC_rll_rel_ind_ACCH_0, - TC_rll_rel_ind_ACCH_3, by adding the 'lazy' version of as_meas_res() alt-step.

2018-10-05BTS_Tests.ttcn: fix: properly detect Measurement ReportsVadim Yanitskiy1-10/+2
The altstep for detecting Measurement Results, that was introduced in I15782ec93d68a0dc54b2ed7a84cb70d780ba0ce1, was implemented in a wrong way. Basically, the DL Measurement Reports (coming from the MS) are being combined with the UL measurements, and then being send as a RSL_MEAS_RES message, not RSL_INITDATA_IND. Let's use the existing as_meas_res() in 'lazy' mode for that. Change-Id: Iea5ee868ede8bfe1e2b1cbf5abcbf2844d3fe9a4

This is a re-submit of change I794e6d4fe8abc67337428cbe0bcc8802fae37a6e, which had to be reverted because the depending patch in osmo-bsc is not yet merged into master.

2018-10-04bts: Use f_L1CTL_PARAM to set expected ms power level for dummy MeasRepPau Espin Pedrol1-0/+1
If for whatever reason (eg. CPU scheduling saturation) the L1CTL cli (TTCN3) doesn't send Measurement Reports on time and no previous one is cached or has been erased by L1CTL_DM_REL_REQ, lower osmocombb layers will generate their own dummy Measurement Reports since SACCH must always be filled. Those dummy Measurement Reports are filled from parameters previosuly set using L1CTL_PARAM_REQ (implemented by f_L1CTL_PARAM() in TTCN3). Since that function is never called, we need to call it to set the expected MS power level values in case the cache is empty and we don't send expected values in case we don't send the Measurement Report through L1CTL on time.

2018-10-04BTS_Tests.ttcn: fix: properly expect I-frames in f_TC_encr_cmd()Vadim Yanitskiy1-4/+27
For some reason, in f_TC_encr_cmd() it was expected / assumed that when a ciphered I-frame is sent from MS on L1CTL, nothing else than this frame would arrive. But since we have fixed Measurement Reporting in trxcon (see OS#2988), the MR related messages do appear on A-bis interface now! This change introduces a new function f_data_mo(), which should be used to send I-frames from MS and expect them on A-bis. So, the following test cases: - TC_encr_cmd_a51; - TC_encr_cmd_a52; - TC_encr_cmd_a53; should pass with both trxcon and Calypso PHY now :) Change-Id: I08cb28dd9fa23f3ef8b0c9ede3d4c47f5702a1c1

2018-10-03BTS_Tests.ttcn: extend f_unitdata_mo() with tolerance parametersVadim Yanitskiy1-2/+18
The ability to control which kinds of RSL messages are permitted in a given use case (and which are not) makes f_unitdata_mo() function much more flexible. Let's introduce two new parameters, one of which would make its 'alt' statement tolerant to SACCH messages (Measurement Reports), and another to other kinds of RSL messages. Please note that the original behaviour of f_unitdata_mo() went untouched, so it's still tolerant to any other messages. Change-Id: I15782ec93d68a0dc54b2ed7a84cb70d780ba0ce1

2018-09-26bts: Account for elapsed time in paging timerPau Espin Pedrol1-21/+44
Previous implementation always waited for "interval" time until sending next paging cmd, and didn't finish the test until all expected paging cmds were sent. As a result, each time it triggered it accumulated some delay which could go from 2 seconds to 12 seconds depending on machine load. As a consequence, the expected number of paging cmd messages to be sent in 20 seconds was being sent in 22-32 seconds, hence changing the load on osmo-bts and as a result changing the test results. Low threshold needs to be adapted since now they are sent in exactly 20 seconds max and the load handled by osmo-bts is bigger. Fixes: OS#3025 Change-Id: I9651136d6810420e0a4d887bfb11c913a24f0457
2018-09-26bsc: inter-BSC HO: add TC_ho_out_of_this_bsc, TC_ho_into_this_bscNeels Hofmeyr8-9/+400
Add f_gen_handover_req() like f_gen_ass_req(), to match AoIP or SCCPlite requirements. For incoming HO, MSC_ConnHdlr needs to know the SCCP addresses to expect the incoming SCCP Connection from MSC to BSC. Add 'handover' section to TestHdlrParams, and pass in the addresses from test_CT via that. In osmo-bsc.cfg, add a remote neighbor config, so that the VTY command 'handover any to arfcn 123 bsic any' can trigger an outgoing inter-BSC HO. Add various BSSMAP handover templates to BSSMAP_Templates.ttcn. Add RR Ho Command template to L3_Templates.ttcn. Move ts_BSSAP_Conn_Req() from msc/BSC_ConnectionHandler.ttcn to library/BSSMAP_Emulation.ttcn, so we can also model an SCCP Connection Request in BSC_Tests.ttcn (this time from MSC to BSC). Add the two new tests to bsc/expected-results.xml. Related: OS#2283 Change-Id: Id22852d4be7f127d827e7a8beeec55db27c07f03
