From libosmo-sccp.git Icffda98579e676ab6ca63c9c22cf5d151c4fe95f on, we expect
an IPA ID ACK upon first connecting, not an IPA ID GET. This might be specific
to the one MSC tested so far, but it's the status quo.
Make the IPA server in IPA_Emulation configurable, to conform and send the IPA
ID ACK upon connecting. This fixes the ttcn3-bsc-tests,SCCPlite suite, broken
by above libosmo-sccp commit.
For other IPA clients, it is so far required to send the IPA ID GET, so only
configure the SCCPlite server in BSSAP_Adapter.ttcn to send IPA ID ACK, and
leave the others unchanged.

I was able to reproduce the sporadic cr_before_reset failures by running
both osmo-{stp,msc}-master with --cpus 0.1. In that case the first test
run would fail for me because no BSSMAP RESET ACK was seen. Sleeping
some seconds before sending the messages will make sure all components
are connected.
Note: TC_cr_before_reset is the first test executed in control so this
seems to be why it sometimes fails in jenkins.

Add tests TC_tch_sign_l2_fill_frame and TC_tch_sign_l2_fill_frame_dtxd.
TC_tch_sign_l2_fill_frame is already passing and verifies that fill
frames are sent if there is nothing else to transmit on a SDCCH4/SDCCH8,
TCH/H, or TCH/F signalling channel where DTX is disabled for downlink.
TC_tch_sign_l2_fill_frame_dtxd is currently failing. It verifies that
only specific fill frames are sent, as required by GSM 05.08 for TCHF
signalling channels with DTX enabled for downlink. At present, our
implementation generates no fill frames in this case, which is one
piece of the problem described in issue OS#1950.

TC_two_crcx_and_one_mdcx_rtp_ho sometimes failed while trying to send an
RTP packet without a connected port. f_flow_modify re-bind()s the port,
sends the MDCX and then connect()s it after the MDCX ACK returned the

If the transmit timer fires off between the bind and connect the
resulting send call will fail.

Sometimes (under heavy load and when the last paging cmd arrives near
the reset ack) some messages are not enqueued in the IPA_RSL port after
we have received the reset ack from BSSAP.
In the failures I have seen wireshark reports that no paging cmd arrived
after the reset ack, see jenkins job 285:
https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-bsc-test/285/
Adding a sleep is always a bit crude, but since the paging cmd is
scheduled through TCP while the reset ack is sent through sctp I don't
see another way.
Running the test under load in a loop showed improvements where I was
not able to reproduce the failure with this patch.

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.

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.

As we are about to finish the implementation of GSM TS 09.11,
OsmoMSC will forward all SS/USSD messages over GSUP to HLR,

Let's modify the existing test cases in order to expect and

Pass the CTRL_DETECT_CONNECTION_ESTABLISHMENT_RESULT parameter to
the TELNET port by default. This allows tests to make progress
into an error handling path if they are started while the osmo-*
program they want to connect on VTY is not running.
Observed with osmo-ggsn tests, where if the one test runs
into a VTY connection failure the subsequent test would get
stuck forever in a map() call on the VTY TELNET port.
Teach the function f_vty_wait_for_prompt() about connection
reports by the TELNET module. We may now receive an integer which
represents the socket file descriptor for the telnet connection.
This case was not handled by the previous change made in
commit cb111b21ab. As a result,
BSC tests started failing with "VTY Timeout for prompt" because
the alt-statement in f_vty_wait_for_prompt() would not progress
past the integer sitting on the VTY port's receive queue.

Thanks to Stefan Sperling, a critical bug was discovered in trxcon.
The problem was that length of LAPDm frames was not checked before
passing them to the libosmocoding API. So, if a received LAPDm
frame is shorter than expected (i.e. 23 bytes), then:
- in case of xCCH, there was a heap overflow (detected by ASAN),
so a short frame has been encoded together with some garbage
outside the primitive buffer...
- in case of FACCH, as the length != 23, a frame was recognised
as a speech frame, and also encoded together with some garbage.
Since the bug is fixed (OS#3415), some TTCN-3 BTS tests started
to fail, because most likely it was assumed that trxcon would
pad the frames automatically, but it doesn't and shouldn't.
Let's automatically pad LAPDm frames with 0x2b before sending.

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).

It is legal that two connections use the same codec but negotiate

At the moment we check the error counters of the RTP statistics in
the testcases. However, in most situations we will do the check to
make sure that no errors occurred (all counters == 0). Rather than
having a long tail of if statements in the testcases we should have
a function for this. This also makes it much easier in case we add
more error countes lateron.
- add and use function f_rtpem_stats_err_check()

It seems mtc.stop() alone does not really solve the race conditions when
shutting down components. The error happens when messages are sent on
ports which are no longer connected since the receiving component has
terminated.
Some web search
http://www.ttcn-3.org/TTCN3UCAsia2007/Presentations/TTCN3%20UC%202007%20Concurrent%20TTCN.pdf
suggested that one should stop all components before
calling mtc.stop (slide 38). Slide 33 also mentions the difference
between .stop and .kill. Kill removes the port connections while stop
does not. And I think looking at the logs when the testcase teminates
(through mtc.stop or otherwise) it is internally calling kill on all the
components. So hopefully stopping all components and then stopping the mtc
will fix this nasty issue.
I verified locally that the situation improves between commits now when
running BSC_Tests.TC_paging_imsi_nochan_all 20 times in a loop and
otherwise generating load on the system. It reliably failed before this
patch and I wasn't able to get it to fail with it.

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
