2018-03-12bsc: add TC_ms_rel_ind_does_not_cause_bssmap_resetNeels Hofmeyr1-0/+63
bsc: add TC_bssmap_clear_does_not_cause_bssmap_reset(), but the same triggered by an MS Rel Ind and a BSSMAP Clear Request sent to the MSC first. This test will only succeed once TC_chan_rel_rll_rel_ind() succeeds, i.e. with below osmo-bsc fix. Related: OS#3041 Depends: I0f8c9c4e6b6850b15c70250fd3f88bdf75f9accf (osmo-bsc) Change-Id: Ie4aa2f01c83b40303fa40ed64dbfce372b7cd96c
2018-03-12bsc: TC_chan_rel_rll_rel_ind: expect full MSC Clear RequestNeels Hofmeyr1-2/+16
This test sends a REL IND from the MS and immediately expects an lchan release. Instead, osmo-bsc patch I0f8c9c4e6b6850b15c70250fd3f88bdf75f9accf decides to signal full BSSMAP Clear Request to the MSC first, so expect that first. Note that this test currently fails, and said osmo-bsc.git patch will make this test pass. Change-Id: I737be141b69a250eb6eb38007f8042981c1a31cf
2018-03-12bsc: add TC_bssmap_clear_does_not_cause_bssmap_reset()Neels Hofmeyr1-0/+63
Same as TC_bssmap_rlsd_does_not_cause_bssmap_reset(), but with a proper BSSMAP Clear from the MSC first. Related: OS#3041 Change-Id: If6ca85d7b80a727cbfdabbf07529ced22602734e
2018-03-12bsc: add TC_bssap_rlsd_does_not_cause_bssmap_resetNeels Hofmeyr1-0/+48
A test with BSSMAP Clear involved would also be a nice addition, but this so far tests a direct RLSD from the MSC. (One way to invoke a typical release situation would be a scenario like in TC_chan_rel_rll_rel_ind(), but that test currently fails; another would be to directly invoke a BSSMAP Clear from the MSC first.)

2018-03-12bsc: cosmetic: T_guard timeout: add 'self.stop'Neels Hofmeyr1-1/+4
If the T_guard runs out, unless we self.stop, we might run into this potentially confusing follow-up error: 00:23:04.206712 mtc BSC_Tests.ttcn:322 Dynamic test case error: Copying an unbound value of type @RSL_Types.RSL_Message. 00:23:04.206778 mtc BSC_Tests.ttcn:322 setverdict(error): fail -> error Change-Id: I1d373159483bdd9f74e8944e430913e73c289e03
2018-03-01MSC_ConnectionHandler: make sure altstep existsPhilipp Maier1-1/+0
The altstep as_handover does not exit as each of its branches is equipped with a repeat statement on the end. This trapps us in an endless loop. - remove the repeat statement at the last logical step which is at the RSL_REL_REQ. Change-Id: I8cb57a9fef606f459542708206f5ea4de1def7a1
2018-03-01BSC_Tests: use isvalue() instead of isbound()Philipp Maier1-1/+1
Currently we use isbound() in f_start_handler() to check if the BTS which we want to connect is indeed populated. However. isbound() seems never become true in this particular situation. - Use isvalue() instead of isbound() Change-Id: I25ddd55b7626087570311999b85ec7632b162c06
2018-02-28BSC_Tests: try to avoid race conditionPhilipp Maier1-1/+27
When the test component ends and the underlaying components are shut down. Messages from the system under test may still be picked up and forwared. When a message is handed from one component to one that is already shut down, the testcase is flagged as errornous setverdict(error). An idea to fix thisis to stop all test ports using all port.stop. However, this does not solve the problem entirely. We still observing errors. - add f_shutdown_helper() and call it from the end of each testcase - perform an all port.stop; in f_shutdown_helper() to freeze all communications between the ports of the different components.

2018-02-23bsc: fix TC_paging_imsi_a_resetPhilipp Maier1-1/+3
The testcase TC_paging_imsi_a_reset sends a paging request that causes pagings on all cells. Then it performs a BSSMAP reset and checks if the paging has stopped. In order to be sure that paging requests from before the reset procedure are not mistakenly detected as after-reset-pagings the RSL queue is cleared. However this is only done for IPA_RSL[0], which means IPA_RSL[1] and IPA_RSL[2] still contain old paging requests, which lets the test fail. - Clear IPA_RSL[1] and IPA_RSL[2] as well.

2018-02-23BSC: Add CCHAN_PT recently introduced in RSL_EmulationHarald Welte1-0/+3
RSL_Emulation has recently gained a port for the common channel management messages, but BSC_Tests was not updated with this port, resulting in RSL_Emulation enqueuing messages to the port which then creates dynamic test case failures. Let's simply connect to the port, even though we currently are not interested in any of the messages received there (mainly RSL_MT_BCCH_INFO during startup). Change-Id: Id8a3c4409599783ca4cd0b49f2570bcb3bb34952
2018-02-23bsc: fix testcase TC_paging_imsi_nochanPhilipp Maier1-25/+1
The testcase TC_paging_imsi_nochan assumes that a paging for no channel, with no specifc cell associated and without TMSI is illegal. This is not correct. All these fields have legal values and the TMSI field is optional. - Replace the testcase implementation, use f_pageing_helper() to create the paging.

2018-02-20IPA_Emulation: Make dependencies to RSL/MGCP/SCCP/GSUP conditionalHarald Welte2-2/+4
Let's use the preprocessor to avoid IPA_Emulation pulling *all* dependencies into each and any of our projects. The code readability suffers a bit from the many #ifdefs, but compilation speed increases if we don't have to pull in all those (recursive) dependencies. After all, a BTS test case will never need SCCP, GSUP or MGCP. Change-Id: Ic0231adbd2171214de133d26b3fbf36130ee8aa0
2018-02-19Add tests for OS#2714, "close RSL connections from unknown Unit ID".Stefan Sperling1-0/+67
This adds two new tests: One for RSL, and a second one which performs the same test on the OML port. Both tests open an IPA connection and send a unit ID which is unknown to the BSC. The tests expect the BSC to close the connection immediately. We need to add handling for a socket error in IPA_Emulation because otherwise these tests do not pass reliably as some closed connections are not properly detected.

This allows each ConnHandler to issue telnet commands to the VTY As a side-effect, it puts some more stress on the VTY interface, as each [parallel] DchanHdlr now has its own telnet connection. Change-Id: Ibd726af53219d829286da80b44ea4d9fb2ffdf3d

2018-02-10BSC: do not flush RSL queue early in TC_chan_rel_a_reset()Philipp Maier1-1/+1
When f_expect_chan_rel() is called after receiving the BSSMAP RESET and DISC.ind f_expect_chan_rel() is called. The flush parameter is not set, which means the default flush = true is valid. This leads into an early flush of the RSL Queue and tosses the RSL RELEASE REQUEST we expect, so the test can not pass, even when the BSC sends the RLEASE REQUEST. Looking further up in the code. IPA_RSL[0].clear is called, so the Queue is flushed to get rid of unwanted messages from the IMMEDIATE ASSIGN. There is no need to flush the queue a second time anyway. - Do not flush the RSL queue, set flush=false when calling f_expect_chan_rel() Change-Id: I2962f741e0b13dec08ac6c918d326828beb65a6a
2018-02-08MGCP: remove hack to fake SDPPhilipp Maier1-3/+0

2018-02-08msc: convert bssmap chipher to rsl chiper representationPhilipp Maier1-1/+47
The representation of the chiphering algorithm is different bssmap and RSL. BSSMAP uses a bitmask and RSL a numeric value. For A50 and A51 the values match up by coincidence, from A5/2 onwards they differ. - Add a function to convert the BSSMAP representation to the RSL representation and use the converted value to set up the temlate for the expected RSL message Change-Id: I274c1ff0b5636c48411f994f918e783b468cb3be

2018-01-31bsc: Change expectation in paging testsHarald Welte1-3/+3
When we page an unknown/unsupported CellIdentifier format, OsmoBSC decides to page on all BTSs to be safe. This way we have a chance of making communication happen, rather than breaking it. Change-Id: Ibd0ba986d9e18758b519e852c36f4dbbb6b367ea

2018-01-29bsc: Fix TC_paging_imsi_nochanHarald Welte1-1/+26
The point of this test is to verify that *no* paging messages are sent if "No cell" is given as cell identifier list by the MSC. We can thus not use the existing pageing_helper function, but have to handle this a bit differently. This makes TC_paging_imsi_nochan runs pass. Change-Id: Iec1086bd42f42de1986bb00b91af718977f73b30
