Neels Hofmeyr 0588cadcfd bsc: implement ttcn API and cfg for A5/4
Implement tools for OsmoBSC a5/4 support testing:

- in f_cipher_mode() and f_check_chan_act(), expect Kc128 key as
  appropriate, using recently added g_pars.encr.enc_kc128
- osmo-bsc.cfg: allow a5/4

Neels Hofmeyr 6c388f209d bsc: reduce args to f_cipher_mode()
Instead of passing each part individually, simply pass the entire
TestHdlrEncrParams to f_cipher_mode().

Preparation for A5/4.

Add the kc128 to TestHdlrEncrParams instead of a function arg. kc128 is
so far unused, but will be used in an upcoming patch adding 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.

Neels Hofmeyr 454d792388 bsc: add TC_assignment_codec_amr_startmode_cruft
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

        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.

from the IUT, so those test cases, for which DLCI is not a part
of the testing scenario, would not fail.
