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.

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'.

These tests pass on master, but they should somehow verify the

According to 3GPP TS 29.002, there are two services:
- MAP-MO-FORWARD-SHORT-MESSAGE (see 12.2),
- MAP-MT-FORWARD-SHORT-MESSAGE (see 12.9),
which are used to forward MO/MT short messages.
This change replicates both services as GSUP messages:
- OSMO_GSUP_MSGT_MO_FORWARD_SM_*,
- OSMO_GSUP_MSGT_MT_FORWARD_SM_*.
Please note, that only the 'must-have' IEs are introduced
by this change, in particular the following:
- OSMO_GSUP_SM_RP_MR_IE (see note below),
- 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.

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.

We cannot notify RSL Emulation layer about expecting a specific FN
(during ts_RSLDC_ChanRqd) because we only know the FN after sending the

can happen (verified) that ChanRqd message from BTS arrives and is
handled before we register the RACH req into the ConnectionTable.

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!

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.

There are two distinct types defined for a Mobile Identity LV IE.
One type definition lives in GSM_RR_Types and defines the "canonical"
IE form, with a full octet for the length.
Another one lives in RLCMAC_CSN1_Types which defines how a mobile
identity appears in paging requests. In this case, the length field
is only 4 bits in size. Rename this latter type from MobileIdentityLV to
MobileIdentityLV_Paging and add a comment to highlight this distinction.
TS 144 060 Table 11.2.10.2 explicitly states that only the value
part of this IE matches the definition of the canonical IE as
"defined in 3GPP TS 44.018" (actually, TS 44.018 further redirects
the reader to TS 124 008; see section 10.5.1.4 there).
As an aside, a third definition of the MobileIdentityLV type exists
in MobileL3_CommonIE_Types, which matches the "canonical" form.

From libosmo-sccp.git Icffda98579e676ab6ca63c9c22cf5d151c4fe95f on, we expect
an IPA ID ACK upon first connecting, not an IPA ID GET. This might be specific
to the one MSC tested so far, but it's the status quo.
Make the IPA server in IPA_Emulation configurable, to conform and send the IPA
ID ACK upon connecting. This fixes the ttcn3-bsc-tests,SCCPlite suite, broken
by above libosmo-sccp commit.
For other IPA clients, it is so far required to send the IPA ID GET, so only
configure the SCCPlite server in BSSAP_Adapter.ttcn to send IPA ID ACK, and
leave the others unchanged.

Pass the CTRL_DETECT_CONNECTION_ESTABLISHMENT_RESULT parameter to
the TELNET port by default. This allows tests to make progress
into an error handling path if they are started while the osmo-*
program they want to connect on VTY is not running.
Observed with osmo-ggsn tests, where if the one test runs
into a VTY connection failure the subsequent test would get
stuck forever in a map() call on the VTY TELNET port.
Teach the function f_vty_wait_for_prompt() about connection
reports by the TELNET module. We may now receive an integer which
represents the socket file descriptor for the telnet connection.
This case was not handled by the previous change made in
commit cb111b21ab. As a result,
BSC tests started failing with "VTY Timeout for prompt" because
the alt-statement in f_vty_wait_for_prompt() would not progress
past the integer sitting on the VTY port's receive queue.
