Vadim Yanitskiy eb57062ab8 library/GSM_RR_Types.ttcn: fix 'presence' in tr_PacketUlSglAssign
According to 3GPP TS 44.018, section 10.5.2.16 "IA Rest Octets",
the first bit of Packet Uplink Assignment defines whether it is
a dynamic (1) or single block (0) allocation.

Vadim Yanitskiy 6276b6cf52 PCU_Tests_RAW.ttcn: TC_cs_lqual_ul_tbf: properly check for Dynamic Assignment
According to 3GPP TS 44.018, section 10.5.2.16 "IA Rest Octets",
Packet Uplink Assignment can be either of the following types:

  - single block allocation,
  - dynamic allocation.

The current version of TC_cs_lqual_ul_tbf does not handle single
block allocation, so we need to make sure we got a TBF with
dynamic allocation.

out of f_init_bssgp() to the test case's body.

Vadim Yanitskiy 0eb26621d8 PCU_Tests_RAW.ttcn: add test case for UL link quality adaptation
This change introduces a new test case TC_cs_lqual_ul_tbf, which
is aimed to test the feedback of OsmoPCU on changing link quality
measurements in Uplink Data blocks during an active TBF.

Vadim Yanitskiy 3e1d31808e PCU_Tests_RAW.ttcn: introduce TC_ta_rach_imm_ass to test initial TA
The aim of this test case is to test the correctness of Timing Advance
at the time of TBF establishment. In particular, the test case sends
several Access Bursts (RACH.ind) with increasing 'qta' value, what
causes OsmoPCU to allocate a TBF (Temporary Block Flow) for each
RACH.ind and send DATA.req with Immediate Assignment on AGCH,
containing the expected Timing Advance value.

Vadim Yanitskiy 799cd3f55b library/PCUIF_CodecPort.ttcn: strip padding bytes from PCUIF_data
In Ieefa61232eb215a19a02e490255332e28e23b8f8, I had to revert
I5808954b5c67c3239e795e43ae77035152d359ef, because that change
broke encoding of messages on the PCU interface.

Since we cannot use 'PADDING' attribute until its implementation
is fixed in TITAN, let's work this around by stripping padding
bytes manually in UD_to_PCUIF().

Vadim Yanitskiy f7d9c0f22b Introduce PCUIF, BTS and ClckGen components for RAW PCU test cases
The problem of existing test cases is that they mix IUT (i.e. OsmoPCU)
with OsmoBTS (osmo-bts-virtual) and OsmocomBB (virt_phy). This approach
allows to avoid dealing with TDMA clock indications and RTS requests on
the PCU interface - this is done by OsmoBTS. On the other hand, our test
scenarios may be potentially affected by undiscovered bugs in OsmoBTS
and the virt_phy.

In order to solve that problem, this change introduces a set of new
components and the corresponding handler functions:

  - RAW_PCUIF_CT / f_PCUIF_CT_handler() - PCU interface (UNIX domain socket)
    handler. Creates a server listening for incoming connections on a given
    'pcu_sock_path', handles connection establishment and message forwarding
    between connected BTS components (see below) and OsmoPCU.

  - RAW_PCU_BTS_CT / f_BTS_CT_handler() - represents a single BTS entity,
    connected to OsmoPCU through the RAW_PCUIF_CT. Takes care about sending
    System Information 13 to OsmoPCU, forwarding TDMA clock indications from
    a dedicated ClckGen component (see below), and filtering the received
    messages by the BTS number. Implements minimalistic scheduler for both
    DATA.ind and RTS.req messages, so they are send in accordance with the
    current TDMA frame number.

  - RAW_PCU_ClckGen_CT / f_ClckGen_CT_handler() - TDMA frame clock counter
    built on top of a timer. Sends clock indications to the BTS component.

All components communicate using TTCN-3 ports and explicitly defined sets
of messages (see RAW_PCU_MSG_PT). One noticeable kind of such messages is
events (see RAW_PCU_Event and RAW_PCU_EventType). That's how e.g. the PCUIF
component can notify the BTS component that OsmoPCU has just connected, or
the BTS component can notify the MTC that SI13 negotiation is completed.
Events may optionally have parameters (e.g. frame-number for TDMA_EV_*).

Furthermore, the proposed set of components allows to have more than one
BTS entity, so we can also test multi-BTS operation in the future.

Neels Hofmeyr f6e991c61f Revert "MGCP: fix pattern warning"
For me this change causes MGCP parsing errors:

    setverdict(fail): pass -> fail reason: "Could not extract parameters for code "C""

Apparently the \r is after all necessary to parse MGCP. Maybe the '\r' is
implicit when an '\n' occurs, but the non-SDP part of MGCP has *only* '\r' line
breaks.

This reverts commit a9a52fff15.

According to 3GPP TS 44.018, section 10.5.2.16, IA Rest Octets IE
starting with 'HH' bits may contain one of the following CSN.1
encoded components:

  7 6 5 4 3 2 1 0  Bit Numbers
  H H 0 0 . . . .  Packet Uplink Assignment
  H H 0 1 . . . .  Packet Downlink Assignment
  H H 1 . . . . .  Second Part Packet Assignment

We already have (partial) support for the first two, while the
last type has not been supported so far. Let's add it.

Also, this change introduces several templates for IA Rest Octets
IE and some of its components mentioned above. This would allow
us to abstract the API users from dealing with further changes,
e.g. adding a coding attribute 'CSN.1 L/H' and missing fields.

For some reason TITAN starts padding not from the beginning of
record ImmediateAssignment, but from it's wrapper GsmRrMessage.
As a result, dec_GsmRrMessage() warns about undecoded octets:

  Data remained at the end of the stream after successful decoding '2B2B2B'O

Similarly enc_GsmRrMessage() generates a shorter payload. Let's
work this around by applying PADDING attribute to GsmRrMessage.

Vadim Yanitskiy 9b2a3e8cb8 library/GSM_RR_Types.ttcn: fix ImmediateAssignment coding regressions
Since I403d2141536303a966be7ff51b06c3de202412e6, IA Rest Octets is
a mandatory IE. When changing the definition of ts_IMM_ASS, I forgot
to mark its optional 'lh', 'hl', and 'hh' as omitted explicitly.

As a result, many of our TTCN-3 test cases were broken:

  Dynamic test case error: Using an unbound optional field.

Also, in Ifdcdcf50709fcc03195cb8ef6092977e26f910ec I added an
optional field 'pad' to record 'IaRestOctets'. That was not the
best solution, because padding should be handled transparently.

Let's get rid of that dummy field and equip both 'ImmediateAssignment'
and 'IaRestOctets' records with proper padding attributes. The later
one needs to be marked with 'CSN.1 L/H' attribute in the future, but
for now we should keep it octet-aligned.

Harald Welte 11b734cb10 bts: Test if BTS forwards ETWS Primary Notification to PCU
All MS/UE must be notified of ETWS Primary Notifiations.

Depending on their state, the notification goes different paths:
* CS dedicated mode: BSC sends it as L3 message over LAPDm / DCCH
* CS/PS idle mode: BTS sends paging messages on PCH
* PS TBF active: PCU send Packet Application Info

This tests the last of the three methods by checking that a  ETWS Primary
Notification sent on RSL to the BTS is received by the PCU socket.

Oliver Smith e1c00f022d Revert "bts: f_init_pcu: sleep before connect"
This reverts commit c089b415f5. The
additional sleep caused other tests to break, probably because it
triggered race conditions:
* TC_pcu_socket_connect_multi
* TC_pcu_socket_connect_si3gprs
* TC_si_sched_13_2bis_2ter_2quater

Adjust TC_pcu_socket_verify_info_ind test case error message to mention
OS#4179. This test is flapping now, most of the time the BTS sends a
CellID 0 because it did not receive the real CellID from the BSC yet.

Vadim Yanitskiy 1f4486cfe3 library/GSM_RR_Types.ttcn: fix: IA Rest Octets may have optional padding
According to 3GPP TS 04.08 (version 7.21.0), section 10.5.2.16 and
table 10.5.45, IA Rest Octets IE may contain spare bits. Let's add
an optional field 'pad' to record 'IaRestOctets'.

NOTE: somehow this change crashes my TITAN runtime:

  dec_GsmRrMessage(): Stream before decoding: '2D063F100FE3673A096B0000C800300B2B2B2B2B2B2B2B'O
  *** Error in `././PCU_Tests': malloc(): memory corruption: 0x000000000074a790 ***

while the recent version works just fine.

Vadim Yanitskiy f10bb45899 library/GSM_RR_Types.ttcn: fix: IA Rest Octets is mandatory IE
According to 3GPP TS 04.08 (version 7.21.0), table 9.18, IA Rest
Octets (see 10.5.2.16) is a mandatory IE, not optional.

Vadim Yanitskiy dd6d5d1baa library/PCUIF_Types.ttcn: inform RAW codec about PADDING in PCUIF_data
PADDING is one of the TITAN specific language extensions [1], which
tells the RAW codec that an encoded payload shall end at a boundary
fixed by a multiple of 'padding' unit bits counted from the
beginning of the message.

Let's use it for record 'PCUIF_data', where the fixed-size buffer
is located in between the other fields, so padding will be ignored
by the RAW coding after decoding:

  $HOST: dec_PCUIF_Message(): Decoded @PCUIF_Types.PCUIF_Message: {
    msg_type := PCU_IF_MSG_DATA_REQ (0),
    bts_nr := 0, spare := '0000'O,
    u := {
      data_req := {
        sapi := PCU_IF_SAPI_AGCH (2),
	len := 23,
	data := '2D063F100FE3673A096B0000C800300B2B2B2B2B2B2B2B',
	...
      }
    }
  }

As a result, we don't have to deal with padding manually and
can safely use 'decmatch' statement in the receive templates.

Harald Welte 09538f8bfd bsc: Test suite for CBSP (Cell Broadcast Service Protocol)
In this testsuite, we simulate BTS and CBC by attaching to RSL and CBSP
protocol interfaces of the BSC.  We then issue a variety of CBSP
commands to the BSC and check for corresponding action on both the BTS-
facing RSL as well as responses on the CBSP side.

Harald Welte b522323cbb CBSP: Hack to make receive templates work
For some reason, the 'ifpresent' annotation doesn't work in lists
of templates.  This means we have to re-think the CBSP template
structure at some point.  However, this would be a significant detour
and I'd rather have working tests right now, so we can verify the
actual functionality merged into the BSC right now.
