Neels Hofmeyr 8256ed2aa9 msc: clear the failed SMS when a test is done
If an MT SMS is triggered and not handled in the test, it is so far left behind
when the test ends. That causes Paging to retrigger for that SMS at any later
point during subsequent test runs, causing stray bogus test failures.

Actually remove the SMS from the SMS database and the queue with a new VTY
command: The vty command to clear failed SMS from the db is added in osmo-msc

Philipp Maier 628c005164 MSC_Tests: Add testcase to simulate VLR/HLR failure (SGsAP)
Currently we do not simulate a situation where the HLR is unreachable to
the MSC. Lets add a test wehere the HLR is disconnected and an LU via
SGsAP is tried. The SGs interface should then carry out a reset
procedure.

Philipp Maier d08e7e7fd3 MSC_Tests: fix TC_sgsap_expl_imsi_det_noneps
When a subscriber is detached from non eps services, it gets fully
detached from 2G, which means that the VLR is supposed to remove the
subscriber. Lets check if the subscriber is in deed no longer known by
the VLR.

1.1 send CM Service Request for MO SMMA indication,
1.2 submit MO SMMA indication on DTAP,
1.3 expect MO-ForwardSM-Req on GSUP,

2.0 send MT SMS using MT-ForwardSM-Req on GSUP,
2.1 expect CP-DATA/RP-DATA for MT SMS on DTAP,

3.0 compare both SM-RP-MR values (for MT, assigned by the MSC),
3.1 send MO-ForwardSM-Res for MO SMMA on GSUP,
3.1.1 expect CP-DATA/RP-ACK for MO SMMA on DTAP,
3.2 send CP-DATA/RP-ACK for MT SMS on DTAP,
3.2.1 expect MT-ForwardSM-Res for MT SMS on GSUP.

Philipp Maier a99ad26639 MSC_Tests: individual IMSI for TC_lu_and_mt_sms_paging_and_nothing
The testcase TC_lu_and_mt_sms_paging_and_nothing is currently using an
IMSI that ends on 43. The same IMSI is used by TC_mo_cc_bssmap_clear as
well. Since TC_lu_and_mt_sms_paging_and_nothing is running before
TC_mo_cc_bssmap_clear, the re-use of the IMSI triggers the MSC to
continue the paging procedure. The MSC then eventually tries to deliver
the SMS from TC_lu_and_mt_sms_paging_and_nothing. This will disturb the
execution of TC_mo_cc_bssmap_clear, which then fails.

Lets make sure that TC_lu_and_mt_sms_paging_and_nothing uses an
individual IMSI that is never used again throught the execution of the
testsuite.

At the moment the sgsap always enabled in the testsuite. This means the
testsuite will try to connect the SGs interface of osmo-msc on

Unfortunately the related patches that add the SGs interface to osmo-msc
are not yet merged to master. This causes almost all testcases to fail,
so lets have the SGs interface as an option that we can switch on when
the SGs interface patches are merged to master.

Vadim Yanitskiy 0e392dd81b MSC_Tests.ttcn: introduce TC_lu_and_ss_session_timeout
The idea of this test case is to verify SS session termination
due to expiry of its guard timeout. The timeout value is
intentionally set to a few seconds in order to speedup
test case execution (we don't want to wait 2 minutes).

We expect OsmoMSC to inform both session entities (MS and EUSE)
about timeout expiry before releasing the transaction. The MS
should receive GSM 04.80 RELEASE COMPLETE message with optional
cause, while the EUSE should receive OSMO_GSUP_MSGT_PROC_SS_ERROR.

At the moment, it's not clean which cause values should be used:

  - for GSM 04.80 RELEASE COMPLETE the cause IE is optional,
    and possible values are defined in GSM TS 04.08, annex G-H.
    The H.6.7 Cause No. 102 "recovery on timer expiry" seems to
    be suitable;

  - for OSMO_GSUP_MSGT_PROC_SS_ERROR the generic cause IE could
    be used, but actually this IE is not generic at all, and
    limited by 'gsm48_gmm_cause' enum;

so we temporarily expect arbitrary cause values in both messages.

Vadim Yanitskiy 2daf52d3a3 msc/USSD: introduce TC_lu_and_mo_ussd_mo_release
The idea of this test case is to check the reaction of OsmoMSC
on MS-initiated release during an active transaction. In other
words, when the network is waiting for some response from a MS,
subscriber can press the 'red button' in order to terminate
this conversation.

It is expected that the MSC would terminate the transaction
as on DTAP interface, as on GSUP interface.

Vadim Yanitskiy 13e4a2732e msc/USSD: add test cases with network-initiaded SS/USSD
This change introduces two new test cases for network-initiaded
USSD notification and network-initiaded USSD request, which are
based on the existing SS/USSD related test cases.

The idea of TC_lu_and_mt_ussd_notification is to verify that
a network-initiaded USSD notification can arrive subscriber in
IDLE mode using Paging procedure.

The idea of TC_lu_and_mt_ussd_during_mt_call is to verify that
a network-initiaded USSD notification can arrive subscriber in
DEDICATED mode (in this case during a call) on a separate
transaction.

Vadim Yanitskiy 747689e13d msc/USSD: expect and reply SS/USSD messages over GSUP
As we are about to finish the implementation of GSM TS 09.11,
OsmoMSC will forward all SS/USSD messages over GSUP to HLR,
and will expect responses back from HLR. The SS/USSD payload
processing will be out of scope for OsmoMSC itself.

Let's modify the existing test cases in order to expect and
reply SS/USSD messages over GSUP protocol.

Vadim Yanitskiy ce8cc37857 msc/USSD: introduce common GSUP/DTAP matching functions
In order to avoid code duplication in the upcoming test cases,
let's introduce a few functions which basically do a GSUP/DTAP
message matching within the alternative statement.

Daniel Willmann aa14a3833d msc: Fix random error of TC_cl3_rnd_payload
The random length for that test could go out of bounds leading to a
Dynamic test case error when sending the message.
The limiting field here is the lengthIndicator of PDU_BSSAP which
includes the length of the PDU_BSSMAP mesageType, cellId as well as the
layer3 info IE and lenght indicator additionally to the l3info payload.
So maximum length for the payload can only be 240 bytes (if the cell ID
is encoded in the longest possible way as BSSMAP_FIELD_LAC_RNC_CI).

Stefan Sperling c307e689b4 introduce a TTCN3 test suite for SCCP
This test suite acts as an SCCP server on top of M3UA.

SCCP tests are run against the sccp_demo_user program which
can be found in libosmo-sccp/examples. This program must be
started in client mode: sccp_demo_user -c
The SCCP test suite should then work out of the box with
the provided SCCP_Tests.cfg file and this additional change
to sccp_demo_user default point codes:
https://gerrit.osmocom.org/#/c/libosmo-sccp/+/9652/

There is currently only one test, for the libosmo-sccp crash
reported as issue OS#2666. The implementation of this test
is currently using an ugly workaround due to shortcomings of
the M3UA Emulation layer (see source code comments). Whether
a better solution is feasible is still to be determined.

The test requires a patch to the SCCP Protocol Emulation which
has been submitted upstream: https://git.eclipse.org/r/#/c/124552/

Daniel Willmann 9b0235b68d Reply to wildcard ep in CRCX with a concrete endpoint
BSC_ConnectionHandler.ttcn:563 This helps TC_gsup_cancel which
previously encountered a Dynamic test case error: Using the value of an
optional field containing omit. The test still fails, but this time
because it "Received unexpected BSSAP instead of CM SERV REJ".

The test currently crashes osmo-msc, which is fixed by
I5c30e0f9545fb76615776ff6cc16b56aeb5b043a (osmo-msc).

Stefan Sperling 04fc4bcc18 check for osmo-msc crash upon overlong IMSI
Overlong IMSIs used to trigger an assertion failure in osmo-msc.
This problem has been fixed but there was no test for it yet.

A lazy way of testing for this problem is to send an overlong IMSI
from an existing test which already verifies related behaviour
and would fail if the MSC crashed: TC_lu_by_tmsi_noauth_unknown

However, osmo-msc currently accepts overlong IMSIs and silently
truncates them, so this change as-is currently breaks this test.
But I would argue that osmo-msc's current behaviour is unreasonable
anyway and have proposed a patch to change it:
https://gerrit.osmocom.org/#/c/osmo-msc/+/9739/
With that patch applied to osmo-msc, this test keeps passing.
