Finally, we can get rid of hard-coded octetstrings and control
every field of the Rest Octets we're sending to the IUT.
Note that template 'ts_SI4_default' did not contain any Rest
Octets at all, thus the GPRS indicator was (and still is)
absent. This will be fixed in a follow up change.

Due to a buggy nature of TITAN's padding attributes [1], we cannot
apply them to individual fields of the records that are embedded
into other structured types, like records and unions.
Ensure that encoded System Information messages are padded to
either 23 or 19 octets, depending on their type. In order to
achieve this, rename and wrap the external encoding function.

As it turned out, the length constraints introduced in [1] were
too strict. In particular, the use of FIELDLENGTH attribute made
it impossible to assign an octetstring of a smaller size and then
pad the remaining octets with '2B'O. TITAN would just use '00'O
instead, ignoring all my attempts to talk some sense into it.

* RlcmacUlBlock and RlcmacDlBlock gain a new union field "egprs_data",
which is chosen when msg contains an egprs data block. Hence one can
use same structure for both gprs/egprs data and simply check
"ischosen(block.data_egprs)" to know whether it contains egprs or gprs
data block.
* C++ code in RLCMAC_EncDec.cc takes care of encoding and decoding of
each data header type and exposes a generic ttcn3 struct
"UlMacDataHeader" and "DlMacDataHeader". Decoded header type can be
found in mac_hdr.header_type. This can be used t5ogether with CPS to
get the MCS of the message received. Similarly, the encoder will use the
same field to know how to encode the ttcn3 structure.
* In RLCMAC_EncDec.cc order of functions has been ordered to split
between encoding and decoding, and inside these split between Ul and
Dl messages.
* Only encoding of UL HeaderType3 and decoding of Dl HeaderType3 is
implemented so far in RLCMAC_EncDec.cc. However, all code is already
arranged and functions prepared (with FIXME fprintf) to easily add the
missing header types once needed.
* Actually only the decoding of DL HeaderType3 has been tested to work so far.
Encoding may still be missing to octet-align the data block after the header.

This change introduces three similar test cases:
- TC_egprs_pkt_chan_req_signalling,
- TC_egprs_pkt_chan_req_one_phase,
- TC_egprs_pkt_chan_req_two_phase,
which basically send several 11 bit RACH.ind messages to the IUT
containing different variations of EGPRS Packet Channel Request.
Depending on the establisment cause, for each RACH.ind we expect
to receive an Immediate Assignment containing an EGPRS Packet
Uplink Assignment in its Rest Octets.
All test cases make sure that Request Reference in the received
Immediate Assignment messages is set to 127 as required by 3GPP
TS 44.018 (see table 9.1.8.1, note 2b), and the Extended RA IE in
the Rest Octets matches 5 LSBs of the RA value that was sent.

By default, the BYTEORDER for BIT1..N sub-types is set to 'first'.
This may result in incorrect decoding of bit-fields located on the
boundary of two octets. For example:
IA Rest Octets
L... .... = First Discriminator Bit: Low
.H.. .... = Second Discriminator Bit: High
..0. .... = Discriminator bit: EGPRS Packet Uplink Assignment
...0 .... = Downlink/Uplink: EGPRS Packet Uplink Assignment
EGPRS Packet Uplink Assignment
.... 0001 1... .... = Extended_RA: 3 // <------------ (!)
.0.. .... = Access Technologies Request: Not Present
..1. .... = TFI/Multiblock: TFI Assignment Present
...0 0000 = TFI_Assignment: 0
As can be seen, the field 'Extended_RA' in this particular case
occupies 4 LSBs of the first octet and 1 MSB of the second. So
instead of '00011'B, TITAN's RAW codec decodes '10001'B.

* Semantic:
We don't really know which side the MSC first creates a CRCX for. Instead of
assuming that the RAN side is always CRCX'd first, simply handle a "first" and
a "second" CRCX, not making any assumptions which is for which side.
Notably, there still are quite a few places assuming which CRCX corresponds to
the RAN/CN side, but the changes are sufficient to still pass the tests when
osmo-msc swaps the CRCX order; sometimes for slightly obscure reasons, for
example because it doesn't matter that the wrong port number is returned during
a subsequent MDCX... Cleaning up the rest is still todo for later.
Remove code dup from call establishing code, particularly for MGCP.
Use f_mo_call_establish() and f_mt_call() where ever possible, to make all of
the call establishing tests handle upcoming changes in osmo-msc's order of
messages, without re-implementing the changes for each test individually.
The X-Osmux parameter was so far expected to appear in the first CRCX received,
assuming that this first CRCX is for the RAN. Instead, detect whether X-Osmux
is contained in a CRCX, and reply with an Osmux CID if so, regardless of it
being the first or second CRCX. Count the number of X-Osmux parameters
received in CRCX messages, and compare after call setup to verify X-Osmux
presence.
Since f_mo_call_establish() can't handle RANAP assignment, a few Iu tests that
worked with the older code dup will break by this patch. This is fixed by a
subsequent patch, see I0ead36333ab665147b8d222070ea5cf8afc555ec.
* Details, per patch chunk:
Change ts_BSSMAP_IE_AoIP_TLA4 to a non-value template, so that we can use a
wildcard for the assigned port number from MGCP (depending on RAN or CN CRCX
first, the RAN port number can be one or the other).
In CallParameters, move MGCP handling instructions into a separate record
"CrcxResponse", and have two of them for handling the first and the second
CRCX, replacing mgw_rtp_{ip,port}_{bss,mss} and mgcp_connection_id_{bss,mss}.
In CallParameters, add some flags for early-exiting call establishment with a
particular desired behavior, for specialized tests.
In CallParameters, use common default values and don't repeat them in each and
every call establishing test.
Set cpars.mo_call := {true,false} implicitly when f_{mo,mt}_call_establish()
are invoked.
Remove CRCX comments implying RAN or CN side, instead just talk of the "first"
and the "second" CRCX.
Implement one common f_handle_crcx() function, which is used by
f_mo_call_establish(), f_mt_call_complete(), as_optional_mgcp_crcx(), and
implicitly uses the first/second CRCX handling.
For Assigment, use a wildcard RTP port so that we don't have to assume which
CRCX was for the RAN side.
In f_mo_call_establish(), insert special case conditions to make it enact
errors at specific times, for individual tests. That saves re-implementing the
entire call establishment (code dup).
For error cases, add expectation of a CC Release message in the call
establishment. This should not apply for normal successful operation, but
because interleave does not support conditionals, add flags
got_mncc_setup_compl_ind and got_cc_connect to break the interleave when
establishing is complete, so that the CC Release is skipped.
A CC Release always breaks the interleave, at whatever time it arrives.
Tests adopting f_{mo,mt}_call instead of code dup:
f_tc_mo_setup_and_nothing()
f_tc_mo_crcx_ran_timeout()
f_tc_mo_crcx_ran_reject()
f_tc_mo_release_timeout()
f_tc_mo_cc_bssmap_clear()

Since there can be multiple PDCH channels configured on different
timeslots, different TRXes, and BTSes, the PTCCH/U handling code
in OsmoPCU needs to know the exact origin of a given RACH.ind.
Otherwise, it is not known which subscriber originated a given
PTCCH/U indication, and hence it is impossible to send PTCCH/D
Timing Advance notification properly.
Fortunately, we can extend the RACH.ind message without even
bumping the protocol version, because every single PDU has a
fixed size defined by the largest message - INFO.ind. In case
if the actual message payload is smaller, the rest is filled
with a constant padding byte (0x00).
Older versions of OsmoPCU will consider the new fields as padding,
while the messages from older OsmoBTS versions will always have
both fields set to 0x00. Since C0/TS0 cannot be configured to
PDCH, this can be easily detected on the other end.

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().

This change implements UL Packet Resource Request message as per
3GPP TS 44.060, section 11.2.16 (only mandatory fields), and a

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.

The PADDING seems to be a very experimental feature of TITAN. It works

Both 't_IMM_ASS_TBF_DL' and 't_RR_IMM_ASS_TBF_DL' templates were
introduced for a specific task - matching Packet Immediate
Assignment (Downlink TBF) by TLLI.
In the upcoming changes we will also need to match Uplink TBF
assignment, and more generic fields such as Timing Advance.
Let's add a generic template for Packet Immediate Assignment
and allow passing IaRestOctets as a parameter.
Change-Id: I492cf990820ba153ea71469b8b623e56e031e549
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.
Change-Id: Ib3a21e7c5fa1cad4466e3a09fa70540de7f6ecc5
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.

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.

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.

The idea of this test case (as can bee seen from its name) is to
verify handover RACH detection. What we basically do is:
1. Activate a logical channel on the BTS side (HO_SYNC for now);
2. Switch the MS (e.g. trxcon) to that channel without waiting
for Immediate Assignment and sending Access Burst;
3. Send an Access Burst on that channel using RA = HO_REF;
4. Wait for RSL HANDOver DETected from the BTS;
5. Release a dedicated connection.
There is no way to verify if the Handover Reference received
from the MS matches the one that was sent to the BTS. We can
introduce a separate test case that would just send an Access
Burst with RA != HO_REF.

In the documentation of Eclipse Titan compiler before [1] it was clearly
stated that if the length of the actual value can be determined and it
is less than the specified FIELDLENGTH, the remaining bits / bytes will
be padded with zeros. The attribute ALIGN specifies the sequence of the
actual value and the padding within the encoded field:
Attribute syntax: ALIGN(<parameter>);
Parameters allowed: left, right;
Default value: 'right'.
Since [1], the default value is:
'left' for octetstrings, 'right' for all other types.
[1] 3cbafbd31d
In the most 'BTS_Tests.TC_pcu_*', including both 'TC_pcu_data_req_agch'
and 'TC_pcu_data_req_imm_ass_pch' we do pass the payload of length 23
bytes to ts_PCUIF_DATA_REQ(), what is less than the actual field length
(162 bytes). Thus when using titan.core <= 6.5.3, the payload appears
at the end of the buffer on the BTS side, so it reads 23 zero-bytes
from the beginning and does transmit them.
Let's explicitly add ALIGN(left) to field 'data' of 'PCUIF_data', so
the alignment would be done correctly, as expected by the BTS. Let's
also drop 'OCT162' type, as it doesn't make sense outside the
message definition.
This change makes the following test cases pass:
- 'TC_pcu_data_req_agch' and
- 'TC_pcu_data_req_imm_ass_pch'.

- OSMO_GSUP_SM_RP_DA_IE (see 7.6.8.1),
- OSMO_GSUP_SM_RP_OA_IE (see 7.6.8.2),
- OSMO_GSUP_SM_RP_UI_IE (see 7.6.8.4),
- OSMO_GSUP_SM_RP_MMS_IE (see 7.6.8.7),
- OSMO_GSUP_SM_RP_CAUSE_IE (see GSM TS 04.11, 8.2.5.4),
where both SM_RP_DA and SM_RP_OA IEs basically contain
a single nested TLV of the following format:
- T: identity type (see 'GSUP_SM_RP_ODA_IdType'),
- L: identity length,
- V: encoded identity itself.
According to GSM TS 04.11, every single message on the SM-RL has
an unique message reference (see 8.2.3), that is used to link
an RP-ACK or RP-ERROR message to the associated (preceding)
RP-DATA or RP-SMMA message transfer attempt.
In case of TCAP/MAP, this message reference is being mapped to the
Invoke ID. But since GSUP has no 'Invoke ID' IE, and it is not
required for other applications (other than SMS), this change
introduces a special 'SM_RP_MR' IE that doesn't exist in MAP.

In general, the order of IEs in a GSUP message doesn't matter.
Despite libosmocore's GSUP API encodes IEs in a fixed order,
it is capable to decode them in any arbitary order.
Meanwhile, in the current TTCN-3 definitions (i.e. templates)
the order makes a difference, because the 'GSUP_IEs' type is
a record, that according to the TTCN-3 documentation represents
an *ordered* sequence of elements.
Let's reorder the IEs of both t{r|s}_GSUP_PROC_SS_ERR templates
in a way that is used by the libosmocore's GSUP encoder.
This correction doesn't affect successful test case executions,
because we don't test possible problematic situations yet. But
if something went wrong on the HLR side (i.e. SUT), the matching
statements wouldn't match the PROC_SS_ERR message correctly
and continue to wait until the guard timer is expired.

Both session state and session ID IEs are always being encoded
together by libosmocore's GSUP implementation. So, if a message
contains a session ID IE, session state IE shall also be there.
For some reason, the session state IE was missing in both
ts_GSUP_PROC_SS_ERR and tr_GSUP_PROC_SS_ERR templates. This
could led to incorrect matching in our test cases.
This change fixes both templates by adding the missing IE. Since
tr_GSUP_PROC_SS_ERR templete is used in HLR_Tests.ttcn, all the
affected matching statements were also corrected.

tr_BSSMAP_HandoverPerformed matches all optional fields on "omit". This
does not make much sense as a safe default. Lets match on "*" instead.

Implement a basic paging test for the PCU, which is passing for paging
via TMSI (but only if osmo-pcu is started after the test is started).
Previously, this test code amounted to a debugging loop which
never terminated.

MSC tests were unable to match odd-length digit strings in
a CallingPartyBCD_Number template created by tr_Calling().
This happens because the raw encoder for CallingPartyBCD_Number
pads odd-length digits with 1-bits ('F'H). Do the same when
constructing such a template in our own code to ensure that
we'll match the actual data received.

Add two helper functions which retry a VTY command until the
result matches a regular expression or a configurable timeout
expires.
Use these functions in BSC test's f_ts_dyn_mode_get, which has
seen sporadic failures due to a race condition during channel
reconfiguration, in order to hopefully close this race.

We cannot notify RSL Emulation layer about expecting a specific FN
(during ts_RSLDC_ChanRqd) because we only know the FN after sending the
RACH request, and since notification to RSL Emulation happens async, it
can happen (verified) that ChanRqd message from BTS arrives and is
handled before we register the RACH req into the ConnectionTable.

this allows us to match on specifically 3G MM AUTH REQ, whereas
so far we only had a generic template that matched the 2G and 3G
auth req.

Matching the CONFIG prompt using implicit '\w+(*)' pattern is
a bad idea, because it can actually match almost anything:
- 'OsmoBlaBla(config)# ',
- 'OsmoBlaBla(config) ',
- 'OsmoBlaBla> ',
- 'Mahlzeit'!
One problem is that the parentheses are interpreted as a matching
operator (which is used to group an expression), so they should
have been escaped by '\'. Another problem is that this pattern
is not complete, because '\# ' is missing. Let's fix this!

Otherwise RSL layer fails this way when this event is received:
RSL_Emulation.ttcn:429 Receive operation on port IPA_PT succeeded, message from TC_chan_act_a51-RSL-IPA(3): @IPA_Emulation.ASP_IPA_Event: { up_down := ASP_IPA_EVENT_DOWN (0) } id 9
- Function main_client was stopped. PTC terminates.
RSL_Emulation.ttcn:429 Message with id 9 was extracted from the queue of IPA_PT.
RSL_Emulation.ttcn:430 setverdict(fail): none -> fail reason: "Received unknown primitive from IPA", new component reason: "Received unknown primitive from IPA"
We now fail with a clearer message "Lost IPA connection!". These
failures seem to happen under high load when the BTS doesn't get a
steady clock from osmo-trx.

This function can now be called from anywhere to try and safely shutdown
a testcase. It is not optimal as we can't call "all component.stop" from
outside the mtc, but without any proper and orderly shutdown handling of
all our emulation components I believe this is the best we can do.
To use it:
import from Misc_Helpers all;
in your module and then call
Misc_Helpers.f_shutdown(__BFILE__, __LINE__);
You can also pass the function a verdict and a message and it will take care
of calling setverdict, but beware of the following:
While setverdict would accept any number of arguments as log message
and convert them to a log string f_shutdown expects one charstring.
It's possible to use the log2str function to use the log arguments in
setverdict for f_shutdown, for example
setverdict(fail, "Template didn't match: ", tmpl_foo);
would become
Misc_Helpers.f_shutdown(__BFILE__, __LINE__, fail, log2str("Template didn't match: ", tmpl_foo));

Add another IPA test to the BTS and BSC test suites.
This new test sends the header in one burst, followed by the
payload which is transmitted byte-per-byte.
The test uses an ID REQ message. If acting as a server, the test
can expect an ID RESP message. However, if acting as a client, the
server will close the connection when it receives the ID REQ.
The CTRL interface port on the BSC does not close the connection in
this case, so that particular port is skipped by the test for now.
