Pau Espin 23510fb721 bsc: Drop mp_enable_osmux_test
This module parameter is not needed anymore, since latest already
supports this feature for a while.

Pau Espin e076b3ff86 bsc: Allow disabling dyn TS SDCCH8 tests
With this we'll avoid running the test in latest. This way we'll not
fail after changing the TS for the test and hence other tests won't be
affected.

Vadim Yanitskiy 343c9eba51 BSC: fix channel combinatiron for TS5 in phys_chan_config
In the configuration file, that we use for ttcn3-bsc-test, TS5 is
configured to TCH/H.  However, f_ts_reset_chcomb() would reset
it to TCH/F.  This makes some other test cases fail.

Oliver Smith 26a3db7d70 bsc: change encryption a5 via VTY where needed
Do not assume that osmo-bsc.cfg contains "0 1 3 4" for master and "0 1 3"
for latest anymore. An upcoming test will need to change the value as
the test runs and needs a defined value to reset to.

Assume that osmo-bsc.cfg contains "0 1 3" and change it to "0 1 3 4"
only for TC_ciph_mode_a5_4.

Neels Hofmeyr 04d6e6acb6 bsc: replace TC_assignment_fr_a5_4 with TC_assignment_fr_a5_not_sup
reasons:

* TC_assignment_fr_a5_4() runs an unusual sequence of messages: it first
  fully assigns an lchan, and after that sends a Cipher Mode Command.
  Usually, the ciphering happens as part of attaching (Compl L3).
  The new test TC_assignment_fr_a5_not_sup() does the ciphering in the
  usual sequence, and properly expects a Cipher Mode Reject.

* TC_assignment_fr_a5_4 means to ask for an *unsupported* encryption
  algo. Since we are going to introduce A5/4 support shortly, we'll need
  to free up this name, for a successful A5/4 encryption test.

New test TC_assignment_fr_a5_not_sup() asks for A5/5 encryption, which
is not supported.

Pau Espin 0619995974 bsc: Fix race condition exiting f_ho_out_of_this_bsc
The function didn't wait to receive the 2 messages from the BSC. As a
result, they may have arrived while tearing down the test components
shortly after exiting the function and provoke a Dynamic Test Error
while pushing the messages up the stack since some of the stack layers
may already be unavailable.

Test TC_ho_out_of_this_bsc() workarounded this by using a f_sleep(1),
but TC_srvcc_eutran_to_geran_ho_out() didn't, making it fail sometimes.

Vadim Yanitskiy 79ebd5e4d3 BSC_Tests: fix f_recv_next_si1(): skip unmatched RSL messages
Since Idb453fc894584ccf4f5f8b45a24421db958e9478, osmo-bsc does send
ip.access specific Measurement Pre-Processing Defaults.  This message
currently blocks the 'alt' statement in f_recv_next_si1(), so all
test cases calling it fail due to the guard timeout.

What's even worse, both TC_si_acc_rotate() and TC_si_acc_ramp_rotate()
dynamically configure the IUT in order to re-generate and send System
Information messages periodically.  If any of them fails prematurely,
the related configuration parameters would remain active, so the IUT
would continue sending System Information messages, causing failures
in subsequent test cases.

Let's simply ignore all unmatched messages in the 'alt' statement.

Make sure that when a 'start-mode auto' is set, that the previous start
mode setting does not linger in the unused bits.

- after I577ff590d7588fd7e3ee4846c7955ab8f84cf2b1, osmo-bsc sets its
  ICMI bit properly, but passes this test only because it *always* sends
  smod (start-mode) bits as zero.

- in I49691df01745a7c485bf165e897872c35fc4b147, the smod bits are
  properly sent on RSL, but this test shows that when ICMI becomes zero
  for 'start-mode auto', the smod bits will remain whatever start-mode
  was set in the previous osmo-bsc config. Instead, osmo-bsc should
  clear the smod bits for 'start-mode auto' so that its MultiRate Config
  does not vary depending on what was previously configured.

- in I1ec5bad0bce01cc425ee05ecf70c83ec662a226a, clearing smod is
  implemented and this test is expected to pass.

Neels Hofmeyr a6ab821704 bsc: set the AMR start-mode that the tests expect
osmo-bsc currently has a bug that fails to reflect the correct
start-mode in the AMR MultiRate config IE.

And it went unnoticed that the ttcn tests expect a MultiRate config of
ICMI = 1, even though the used configuration should yield ICMI = 0.
See mr_conf = '2804'O, where the '8' indicates ICMI = 1.

As a first fix of the ttcn3-bsc-tests, configure the BSC according to
the expected ICMI value and Start Mode, i.e. ICMI = 1 and StartMode = 0,
which is configured by 'amr tch-[fh] start-mode 1'. This should make
these tests pass as-is for both the current osmo-bsc as well as an
osmo-bsc where the bug is fixed, with minimal changes to the current
tests. See also OS#4868.

An upcoming patch will add tests for 'start-mode auto'.

Neels Hofmeyr 4f5d7be579 bsc: clarify RESET logging: BSSMAP vs RANAP vs BSSMAP-LE
When a RESET-ACK times out, the logs currently are indistinguishable between
BSSMAP and BSSMAP-LE. Add protocol naming for each RESET / RESET-ACK logging to
make sure the information does not need guesswork.

Example of a test failure shown in jenkins:

  BSC_Tests.TC_unsol_ass_compl
  Stacktrace

  Timeout waiting for RESET-ACK after sending RESET
        BSC_Tests.ttcn:8295 BSC_Tests control part
        BSC_Tests.ttcn:4274 TC_unsol_ass_compl testcase

Nothing conveys that it is (presumably) the background *BSSMAP-LE* timeout
halting the test 5 seconds in, and not an A-interface failure.

Vadim Yanitskiy 2ef6a2f7fb BSC_Tests: fix f_mo_l3_transceive(): relax DLCI matching
Since If4d479a54cad467f53b49065c1c435a4471ac7d2, osmo-bsc started
to send more concrete DLCI values on the A/BSSAP interface.  In
particular, the control channel identification bits now indicate
whether it's SDCCH/FACCH or SACCH channel.

Let's use '?' as the default DLCI template that we expect to get
from the IUT, so those test cases, for which DLCI is not a part
of the testing scenario, would not fail.

breaks compatibility with older versions of osmo-bsc that do not have
IPV6 support. Lets add a module parameter in order to be able to use
IPV4 as default if required.

According to 3GPP TS 44.018, table 10.5.2.21.1 "Mobile Allocation
information element", in the cell allocation frequency list the
absolute RF channel numbers are placed in increasing order of ARFCN,
except that ARFCN 0, if included in the set, is put in the last
position in the list.

Let's verify that the IUT handles this corner case correctly.

Vadim Yanitskiy e7c8c6e00e BSC_Tests/hopping: fix: consider ARFCN of the transceiver itself
The Mobile Allocation IE generated by the IUT includes not only
the list of hopping ARFCNs, but also ARFCN of the transceiver
itself.  This is the correct behaviour, and that's why we see
sporadic test case failures like this one:

  Mobile Allocation IE does not match (tn := 1):
    { len := 3, ma := '001010101011111100000000'B }
  vs expected
    { len := 2, ma := '0010101010111111'B }

The last '0'B bits may look like redundant padding, but actually
only 7 of them are.  The MSB '0'B bit in the last (third) octet
corresponds to pre-configured ARFCN 871.

Since f_TC_fh_params_gen() generates all ARFCNs in GSM-900:

  - in f_TC_fh_params_gen(), pick an ARFCN value from GSM-900;
  - in f_TC_fh_params_set(), change ARFCN of a given transceiver;
  - in f_TC_fh_params_gen_tr_ma(), consider that ARFCN;
  - in f_TC_fh_params_unset(), bring it back to 871.

Pau Espin 24c0599541 bsc: Fix race condition waiting for RESET-ACK
This scenario appeared in jenkins runs of BSC_Tests making
TC_ctrl_msc_connection_status fail (the first test in the suite). I
could however not reproduce it on my local docker setup because it
really seems like a timing race condition.

The scenario is:
TTCN3 -> BSC: RESET
TTCN3 <- BSC: RESET
TTCN3 -> BSC: RESET-ACK

In there, TTCN3's f_legacy_bssap_reset() expected a RESET-ACK to be
received, but it may well be that the other end never saw the RESET and
hence it will never sent the RESET-ACK, since it indicated it became
available afterwards. In that case (RESET received), let's not fail if a
RESET-ACK is never received, since the connection is actually in the
desired state and this scenario can happen and it's all fine.

Vadim Yanitskiy 2aa02529de BSC_Tests/hopping: fix: do not reduce Mobile Allocation bit-mask
My initial assumption was that we can skip redundant '0'B bits or
even '00'O octets in the Mobile Allocation IE, and thus reduce
the overall size of this element.  Unfortunately, this is wrong.

3GPP TS 44.018, section 10.5.2.21 clearly states that the Mobile
Allocation IE contains a bit-string of size NF, where NF is the
number of frequencies in the cell allocation.  If NF % 8 != 0,
then '0'B padding bits must be appended to make it octet-aligned.

In other words, if the cell allocation contains let's say 13
frequencies, but a hopping timeslot makes use of only a small
fraction of it (e.g. 4 first channels), we would still need to
transmit at least 13 bits (+padding), including all redundant
bits and octets.

Harald Welte c47fdb2e52 bsc: Add Lb interface support
This introduces the Lb interface stack, which allows BSC_Tests.ttcn
to emulate a SMLC towards the BSC.

In accordance with https://osmocom.org/projects/cellular-infrastructure/wiki/Point_Codes
we use 0.23.6 as point code for emulating the SMLC.

The idea of these new test cases is to verify that the IUT does
send BSSMAP SAPI N Reject in the following cases respectively:

  - on receipt of an unexpected RLL RELease INDication message
    in response to RLL ESTablish REQuest (for SAPI=3 link);

  - on receipt of an unexpected RLL ERROR INDication message
    in response to RLL ESTablish REQuest (for SAPI=3 link);

  - due to SAPI=3 link establishment timeout.

The bsc/BSC_Tests_CBSP.ttcn rely on a configuration where the first three BTS
carry out SMSCB messaging, and the fourth BTS does not. That requires a CBCH
channel config on bts 0, 1, 2.

Side effects:

- adjust the number of available SDCCH (for TC_chan_exhaustion).

- there now is a CBCH channel description in SI4, add this to
  SystemInformationConfig_default.

In the ttcn3-bsc-latest tests, there are no 'msc 1' and 'msc 2' configured, so
stepping into 'msc 1' and '2' creates two new, empty MSC configurations.
osmo-bsc latest actually still tries to use them and fails 2/3 Compl L3.

Philipp Maier 783681ce42 BSC_Tests: test handling of EMERGENCY SETUP
The EMERGENCY SETUP is an L3 message that normally gets passed through
transparently to the A interface. Nomrally the BSC will not look into L3
messages. However if EMERGENCY CALLS are allowed on a BTS or not is set
in the system information. Also osmo-bsc has the option to deny
EMERGENCY CALLS globally for all BTSs.

Since EMERGENCY CALLS are a crucial application, the BSC should not only
send the appropiate sysinfo messages that forbid emergency calling. It
should also make sure that any attempt to make an emergency call is
rejected early if emergency calls are denied.

Lets add some checks to verify that the allow/deny mechanisms for
EMERGENCY CALLS are working as expected.

Neels Hofmeyr a460f1f9ba fix mscpool cleanup (fixes LCLS tests)
osmo-bsc takes a while to notice that a connected MSC is no longer connected.
Once the mscpool tests have run, the additional msc 1 and msc 2 still linger
around even though the BSSMAP link is no longer served by the bsc-tester.

The easiest way to ensure that only expected MSCs are contacted is to set
'no allow-attach' for each MSC that should not be in use.

So, the default setup is 'allow-attach' on msc 0, and 'no allow-attach' on mscs
1 and 2. In f_init(), allow attach on those MSCs indicated by the nr_msc
amount. The entire vty transaction to configure attach/no attach for all three
MSCs takes about 4 micro seconds in my test setup, so it is fine to do this
during f_init() for each BSC test.

After this, tests running after the MSC pooling tests (the LCLS tests) no
longer round-robin their subscribers across disconnected MSCs.

NOTE: it would be good to somehow detect more reliably in osmo-bsc that an MSC
is gone and not use it anymore. That is however not so trivial. To get the LCLS
tests back online, this is a workaround to avoid that complexity for now.

Neels Hofmeyr 4fbad7fc1a bsc: allow individual T_guard timeout via f_init()
The TC_ho_neighbor_config_* tests sometimes take longer than 30 seconds,
because they run multiple handovers. Since they don't have access to the
Test_CT, they cannot restart the T_guard. The simplest solution is to choose a
longer T_guard timeout for those tests specifically, by adding an argument to
f_init(). (A longer timeout for those tests is following in another patch.)

Why f_init()? Assigning a different default value to T_guard seems to not be
possible, but a different timeout value can be passed to T_guard.start(), which
happens in f_init().

Philipp Maier f45824ad0e BSC_Tests: Change test-expectation of TC_paging_resp_unsol
The testcase TC_paging_resp_unsol expects the BSC to close the channel
when an unsolicit paging response is received. This expectation is due
to the fact that osmo-bsc supports multiple MSC, which is not specified
in 3gpp specs. Therefore the BSC needs to know which MSC is in charge.

However, with MT-CSFB calls it is a normal situation that the BSC
receives a paging response on abis without sending a paging first since
the MSC has paged the UE via the SGs interface. In those cases we expect
the BSC to forward the paging response to the first configured MSC.

Neels Hofmeyr 7e2769f3b1 fix TC_ho_int; make neighbor config more robust
Since osmo-bsc commit "neighbor config: allow re-using ARFCN+BSIC pairs"
(I29bca59ab232eddc74e0d4698efb9c9992443983), osmo-bsc considers only those
cells as neighbors that are explicitly listed, or all local cells if none are
listed. This lead to breaking TC_ho_int, because the osmo-bsc.cfg has only one
remote-cell neighbor for bts 0, and hence a handover to local cell bts 1 is now
regarded as invalid.

The remote-cell neighbor is needed for inter-BSC handover tests; also consider
that the TC_ho_neighbor_config_* tests each place individual neighbor
configuration by live VTY interaction.

Hence make all of these tests more robust: remove the neighbor config from the
osmo-bsc.cfg file, and instead include VTY interaction for each test case that
sets the particularly needed neighbor configuration at runtime.

An analogous osmo-bsc.cfg change in docker-playground is in change
If44dd6b578cdc55076c8180707d1c2d69fe5f2a8.

(It is not actually harmful to leave the neighbor config in osmo-bsc.cfg, but
remove that since it is also not needed anymore.)

Neels Hofmeyr 9140101cb0 bsc: add TC_ho_neighbor_config_1 thru _7
Add tests to play through various neighbor configurations.
Tests will pass as soon as osmo-bsc I29bca59ab232eddc74e0d4698efb9c9992443983
is merged.

Add RSL2 to allow triggering handover to BTS 2.

Adjust osmo-bsc.cfg to match the new tests. Also applied in docker-playground
I1c57a04747f5ec004ccf4657954dcb0b003c24fc.
    - Actually enable handover.
    - Add bts 3

Neels Hofmeyr e1797aab91 f_tc_ho_out_fail_no_ho_detect: stricter ordering
Make sure that the RR is released only after the MSC has sent the Clear Command:
- first expect a Clear Request from osmo-bsc and return a Clear Command,
- only then accept RR release messages.

See 3GPP TS 48.008 3.1.5.3.3 "Abnormal Conditions": "The terrestrial resource
in the old BSS shall remain assigned until a CLEAR COMMAND message is received
from the MSC"

osmo-bsc already complies, the test should continue to pass.

Pau Espin 7aa0274138 bsc: Do proper chan release in TC_ho_out_fail_no_ho_detect
BSC waits to receive a ClearCommand in response to its ClearRequest
before it starts tearing down the MGCP conn on the MSC-side of the MGW
endpoint.

As a result, expected DLCX was not being sent which made test fail.

However, currently test still fails because current osmo-bsc master
sends a repeated ClearRequest message in this scenario.

Pau Espin fd02ad474e bsc: Test MGCP-over-IPA forwarding in SCCPlite tests
* MGCP-over-IPA handling in MSC_ConnectionHandler means we need to use
the new MGCP_CLIENT_MULTI port since we'll be managing MGCP messages
from 2 different UDP connections, and we need to be able to route
answers correctly. As a result, parameter multi_conn_mode is enabled for
SCCPlite and all code adapted to use that port in that type of scenario.
* iDuring calls when on SCCPlite, send a full (all-required-params-in)
CRCX through the MGCP-over-IPA connection towards the BSC in order to
emulate the MSC, and expect the correct answer back. This way we test
BSC funcionality to forward MGCP messages coming from MSC works as
expected.

Pau Espin 1a026a52d3 lib/mgcp: Add new port with support to handle multiple MGCP sockets
* 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.
