Stefan Sperling a2d59c6e6e add three tests for CIPHER MODE COMPLETE without algo
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?

Harald Welte a183a5ddc2 msc: Separate as_GSUP_SAI from f_mm_auth
In some cases we might want to match on (and perform) the GSUP
SEND AUTH INFO without also expecting/performing a MM authentication
on the Iu/A interface.  Hence it makes sense to split those two.

Harald Welte b78179968f msc: Permit optional authentication before reject/timeout
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.

Harald Welte 62113fce7a msc: Don't require protocolExtensions in RANAP Paging
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

Neels Hofmeyr 2ca1ab492a msc: mo and mt voice call tests: add lots of missing parts
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.

Neels Hofmeyr 1623774b68 msc: expect only one Paging on failed MT SMS
An MSC might decide to repeatedly retry Paging if it failed the first time, but
osmo-msc currently has no such mechanism. Instead, it so far had a bug that
retriggered a failed Paging from a start in a situation where there are SMS
pending for only one subscriber, and sending the SMS fails. osmo-msc patch
I24bf9f1c1167efe1080ae4cf47ed2ef0bd981e49 changes this behavior to accept a
Paging failure and not launch the same SMS again numerous times.

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

point during subsequent test runs, causing stray bogus test failures.

command: The vty command to clear failed SMS from the db is added in osmo-msc

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.

Vadim Yanitskiy d7b37ab851 MSC_Tests.ttcn: introduce TC_gsup_mt_sms_{ack|err}
The idea of this test case is to verify MT SMS transmission
initiated by ESME over GSUP. Basically, the algorythm is
the following:

  1.0 send MT-ForwardSM-Req on GSUP,
  1.1 expect Paging Request on RAN,
  1.2 establish a RAN connection,
  1.3 expect CP-DATA/RP-DATA on BSSAP/DTAP,
  2.1 send CP-DATA/RP-ACK on BSSAP/DTAP,
  2.2.a expect MT-ForwardSM-Res,
  2.2.b expect MT-ForwardSM-Err.
