Vadim Yanitskiy 6de2fcbfe9 library/RSL_Emulation: server mode: handle multiple transceivers
Since change [1], the IPA emulation component allows us to handle
multiple IPA connections, thus multiple RSL connections. The idea
is to attach a TCP/IP connection identifier to each message.

On top of that, this change implements mapping between TCP/IP
connection identifiers and RSL stream identifiers, so we can
finally talk to any of connected transceivers (up to 4 for now),
not only the last connected one (as it was before). The actual
mapping is done during the IPA identification procedure.

Instead of forwarding ASP_IPA_EVENT_UP to a test case, the RSL
emulation component now sends a new event - RSLEM_EV_TRX_UP,
with transceiver number (actually, IPA stream-id) attached.

Vadim Yanitskiy ef9bcd21ba library/IPA_Emulation: handle optional conn_id in ASP_RSL_Unitdata
This would allow the RSL Emulation component to maintain several
transceiver connections in server mode. In order to send an RSL
message to a specific transceiver, its TCP/IP connection ID needs
to be included in the ASP_RSL_Unitdata message.

Vadim Yanitskiy 6643e8d3c7 library/IPA_Emulation: server mode: handle multiple client connections
This change basically does two simple things:

  a) adds TCP connection identifier to ASP_IPA_Event,
  b) splits g_ipa_conn_id into g_self_conn_id and g_last_conn_id.

Change a) would let the upper layers of code (based on the IPA
emulation component) know which TCP/IP connection a given event
belongs/relates to.

Change b) solves the problem, happening in server mode when a new
client connects, and TCP/IP connection identifier of another
previously connected client gets overwritten.

With this change applied, g_self_conn_id holds TCP/IP connection
identifier of the client or server itself (depending on g_mode),
while g_last_conn_id is only used in server mode and holds
connection identifier of the last connected client.

As a side effect of change [1], the RSL emulation component has

TRX#0. Let's fix this by using template '?' for stream ID.

Pau Espin 02c972d8aa pcu: use correct RA type to properly test 2phase access
Old code was not setting Single Block Packet Access type, and 2phase
access was not properly triggered.

Once it's triggered, message flow changes quite a lot from the 1phase
access, specially because the 2nd Ul Assignment arrives through PDCH
instead of CCCH, which means a different record is received and hence
code for 1phase cannot be easily re-used.

For similar reasons, f_tx_rlcmac_ul_n_blocks() is modified to receive
the only required tfi param instead of a full dl_block.

Some functions are also extended to support SingleBlock Allocation
instead of usual DynamicAllocation.

Neels Hofmeyr b2168516f3 hlr: add tests for GSUP proxy routing
GSUP proxy routing, as it is implemented in an upcoming osmo-hlr patch,
requires that osmo-hlr returns a received Source Name IE back as Destination
Name IE. Add tests for these, for various situations.

These tests pass since GSUP request handling with request->response association
was introduced to osmo-hlr in I179ebb0385b5b355f4740e14d43be97bf93622e3.

Implement this by adding a source_name to the g_pars, which should be sent out
in ts_GSUP_* to osmo-hlr, and expected back as destination_name in returned
messages.

Add source_name and destination_name to various templates, with default :=
omit.

Add f_gen_ts_ies() and f_gen_tr_ies() to compose expected IEs more generically.

Vadim Yanitskiy b6733a67ec PCU: refactor and simplify f_rx_rlcmac_dl_block_exp_data()
This function was written in a way that it tries to do as
many different (but related) things as possible:

  a) send an RTS.req to the IUT, expect a DATA.ind in return,
  b) decode RLC/MAC message contained in the received DATA.ind,
  c) make sure that it's either GPRS or EGPRS data block,
  d) calculate the last TDMA frame number of RRBP using
     f_rrbp_ack_fn() regardless of its validity,
  e) make sure that the block contains a given LLC payload.

Everything is ok except point d). The problem is that this is
only the case for the first block of RRBP, and not applicable
to the rest having 'rrbp_valid' flag unset. Furthermore, this
function did not match GPRS DL blocks with 'rrbp_valid' flag
unset, for some odd reason.

Let's move RRBP calculation into a separate function called
f_dl_block_ack_fn() and return TDMA frame number of the
received DATA.ind message instead.

Among with that, there are more little changes:

  - simplify matching of (E)GPRS DL data blocks,
  - use 'in' qualifier in parameter list where possible,
  - turn parameter 'data' into a template (present).

Due to a buggy nature of TITAN's padding attributes [1], we cannot

Ensure that encoded System Information messages are padded to

achieve this, rename and wrap the external encoding function.

instead, ignoring all my attempts to talk some sense into it.

Pau Espin 372af7a116 library/RLCMAC: Add partial support for EGPRS data block encoding/decoding
* 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.
  All these wil lbe fixed once a test using them exists.

Vadim Yanitskiy a0b47cf825 PCU: add test cases for EGPRS Packet Channel Request
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.

Vadim Yanitskiy 1175b5e509 library/GSM_RR_Types.ttcn: fix: apply BYTEORDER(last) globally
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.

  2) the IUT prints an invalid P-TMSI in its log output
