2019-10-04MSC_Tests.ttcn: fix race condition in f_tc_proc_ss_paging_fail()Vadim Yanitskiy1-2/+3
Sometimes in TC_proc_ss_paging_fail we hit a race condition. The problem is that the paging expiration timer in OsmoMSC is set to 10 seconds by default (see MSC_PAGING_RESPONSE_TIMER_DEFAULT), and in f_tc_proc_ss_paging_fail() we also wait 10.0 seconds. Let's increase our timer value to 20.0 seconds, so there will be more 10 seconds of leeway. Change-Id: I6983e8c0cc8e1d7d1619f127e80063d71a4759d2 Related: Jenkins ttcn3-msc-test build #677
2019-09-28msc: add f_tc_lu_and_mt_sms_paging_repeatedAlexander Couzens2-0/+53
The testcase will ensure paging is repeated by the MSC. Repeating will improve the reachability of MS when a Paging is lost or not received because the MS is moving between states. Change-Id: Ib5bf0b62e0639436cdcba03acbaedf1458e18873
2019-09-24MSC_Tests: Expect SGsAP-SERVICE-ABORT-REQUEST on paging timeoutPhilipp Maier1-3/+21
When a paging for a CS-Call times out the MSC/VLR is expected to send an SGsAP-SERVICE-ABORT-REQUEST to the MME to indicate that the paging has timed out. This is not taken into accound yet by TTCN3 test TC_sgsap_paging_and_nothing Related: OS#3614 Depends: osmo-msc I3f8f153afe24cf2efa245713509bdc8488902877 Change-Id: I99950a17ccf26aaa0eebded5480f33be4c57586a

2019-08-18MSC_Tests: do not send an SGsAP-MO-CSFB-INDICATION when testing MT-CallPhilipp Maier1-3/+0
The TTCN3 tests MSC_Tests.TC_bssap_lu_sgsap_lu_and_mt_call and MSC_Tests.TC_sgsap_lu_and_mt_call initate an MT-CSFB call for testing purposes, but they also send an SGsAP-MO-CSFB-INDICATION to make the MS come back to LTE. This is wrong. SGsAP-MO-CSFB-INDICATION just informs the VLR that the UE has initiated a MO CSFB call on the LTE side. On MT CSFB calls this message should not appear. Lets remove it.

2019-07-23msc: use f_expect_clear() in check IMEI testsOliver Smith2-9/+9
Fix the broken pipe race condition caused by closing the RAN connection too early. Properly wait for clear command and send clear complete. TC_lu_imsi_auth_tmsi_check_imei_{nack,err} do not pass anymore, because OsmoMSC is sending the LU reject twice. Patch [1] fixes it.

2019-07-12msc: add check IMEI testsOliver Smith3-3/+400
Extend BSC_ConnHdlr with new check IMEI related parameters. Add tests for check IMEI and check IMEI early for multiple auth variations, as well as variants where the HLR would respond with NOK or ERR. Note that we can safely set "check-imei-rqd 0" in f_init(), because the latest OsmoMSC version already suppors this VTY command. Two tests do not always pass, sometimes the RAN connection breaks before the test finishes (TC_lu_imsi_auth_tmsi_check_imei_err and TC_lu_imsi_auth_tmsi_check_imei_nack). I have added them as expected errors in the expected-results.xml. Related: OS#2542 Change-Id: Ic34bb8dc8547cafb5a53df03884554dd4f72956d

2019-06-24lib/mgcp: Add new port with support to handle multiple MGCP socketsPau Espin Pedrol1-1/+2
* Some scenarios like MGW BSC-attached in SCCPlite require handling of 2 MGCP-over-UDP sockets in MGCP Emulation: 1 for regular libosmomgcp-client from osmo-bsc and another one from the forward socket from osmo-bsc (of MGCP-over-IPA messages communicated with MSC). * Old port is kept for backward compatibility with other tests and enabled by default. It's also interesting to keep it because it makes tests without special needs (2 sockets) to use the old port/API which produces simpler code to read and mantain. * Users of the new port have to enable multi_conn_mode parameter and expect to interact with port MGCP_CLIENT_MULTI instead of MGCP_CLIENT, which will offer messages containing information about the UDP connection being used by that message.

2019-06-16MSC_Tests.ttcn: introduce TC_proc_ss_abortVadim Yanitskiy1-0/+86
This test case is aimed to verify HLR-/EUSE-initiated abort of an active SS/USSD session according to the following scenario: 1. (HLR/EUSE -> MSC) GSUP_PROC_SS_REQ with random facility; 2. Network-originated connection establishment: 2.a. (MSC -> BSC -> MS) Paging Request; 2.b. ... 2.c. (MS -> BSC -> MSC) Paging Response; 3. (MSC -> MS) GSM 04.80 REGISTER with random facility; 4. (HLR/EUSE -> MSC) GSUP_PROC_SS_ERR (abort); 5. (MSC -> MS) GSM 04.80 RELEASE COMPLETE; 6. Connection release. As can be seen, HLR/EUSE initiates the session abort right after the GSM 04.80 REGISTER message is delivered to the MS, and just before the MS sends anything back in response.

2019-06-16MSC_Tests.ttcn: introduce TC_proc_ss_paging_failVadim Yanitskiy1-4/+64
The idea of this test case is to check that OsmoMSC does inform HLR/EUSE that a subscriber did not respond to Paging Request in case of network-originated SS/USSD. Both f_expect_gsup_msg() and f_expect_dtap_msg() were extended with optional timeout value, as we need to wait longer than 2.0 seconds (default). Let's stick to 10.0 seconds.

The idea of this test case is to check that OsmoMSC properly rejects SS/USSD requests for unknown subscribers. Running this test case against the current OsmoMSC helped to discover several problems: - OsmoMSC doesn't print anything in such cases; - IMSI in the response error message is empty; - both session state and ID IEs are omited; which are going to be fixed soon.

2019-06-03msc: Fix Iu tests timing out due to explicit CM ServiceAccept not recvdPau Espin Pedrol1-1/+1

2019-05-31msc: Enable/disable osmux always based on testPau Espin Pedrol1-1/+5
Initially it was thought safe to only enable it since the osmux test was at the end, but actually IU tests run after it, and those don't expect osmux to be enabled. This way we also always match osmo-msc osmux state with whatever the test expects (and sets through f_init()). Change-Id: I8fb48af7d37f1a2391a39c19f5ec5064cd5869d2

2019-05-11add three tests for CIPHER MODE COMPLETE without algoStefan Sperling3-3/+107
Add three tests which exercise MSC behaviour when a CIPHER MODE COMPLETE command lacks the optional chosenEncryptionAlgorithm IE. Check for behaviour with A5/1, A5/3, and A5/1 + A5/3 configured in the network, and expect the location update to succeed. These tests pass on master, but they should somehow verify the cipher the MSC ends up using. I am not quite sure how to do that. Would inspecting the MSC's VTY be a reasonable approach? How could his be done by code which runs on BSC_ConnectionHandler? Change-Id: I1a2a126795c544613a7a87e238e1fc8c4e943885 Related: OS#2872

2019-05-09msc: Permit optional authentication before reject/timeoutHarald Welte1-0/+3
Tests like TC_lu_imsi_reject, TC_lu_imsi_timeout_gsup and TC_cmserv_imsi_unknown all expected a reject straight in response to the LU REQ / CM SERV REQ. However, the MSC may very well decide to perform authentication beforehand. It's an implementation detail when a MSC/VLR performs authentication, so the tests should be tolerant to this. This primarily shows up in 3G/Iu/RANAP related tests, as authentication is mandatory there. Change-Id: Icdd3f34eca08092703ab2ba9a8e755e2d609a59b
2019-05-09msc: Don't require protocolExtensions in RANAP PagingHarald Welte2-4/+4
We were using '?' for the protocolExtensions in RANAP messages, which required that such extensions existed. In reality, we want to use '*' which accepts paging messages whether or not there are any protocolExtensions present. As this is the default in all our RANAP receive template, callers don't even need to specify it. This should fix all Iu paging related test failures in MSC_Tests*.ttcn Change-Id: If22e16ecb301c86b9073ffde0af9e03bc85fbcc7

2019-05-07msc: mo and mt voice call tests: add lots of missing partsNeels Hofmeyr2-84/+196
Both f_mo_call_establish() and f_mt_call_establish() were testing barely half a voice call setup. For example, f_mo_call_establish() used to be satisfied with just two CRCX, but no actual RTP connections being made. Add numerous MNCC and MGCP messages more closely resembling an actual call. The main reason is to achieve a state that passes both current osmo-msc master as well as the upcoming inter-MSC Handover refactoring. Add log markers to f_*_call_*(): often when a test halts, it is not at all clear why. With these log markers it is saner to figure out what has happened and what hasn't.
