Changes

deps: use a fork of titan.ProtocolEmulations.SCCP

The fork adds support for sending UDTS via
ASP_SCCP_N_NOTICE_req.

Change-Id: I8c0de4dab088930d5d7a9febcbebcb5e1f9411e8

stp: add ASP_SCCP_N_NOTICE_req support and f_asp_tx_notice()

Wire ASP_SCCP_N_NOTICE_req as a simple passthrough in TCAP_CODEC_PT,
so test components can send UDTS via the existing SCCP_TCAP port.
Add f_asp_tx_notice() to STP_Tests_TCAP as a convenience wrapper.

CCID: Check if reader times out after first status word

A case 1 APDU is sent towards the reader. The reader expects two status
words. If only the first word is sent by the SIM, the reader must
timeout and send an error message back to the host.

CCID: Send a wrong procedure byte towards the reader

A case 2 request (according to ISO 7816) is sent and a response with
data is expected, but the first byte replied by the SIM is not a
procedure byte, nor a valid status byte.

This text expects the reader to return an error that states an incorrect
received procedure byte.

eIM, IPAd: migrate from SGP.32 V.1.0.1 to SGP.32 V.1.2

SGP.32 V.1.2 is not backward compatible to SGP.32 V.1.0.1. This patch updates
the ASN.1 specification and the TTCN3 templates and types accordingly.

It also applies the bare minimum of changes required to compile the eIM and IPAd
testcases.

STP_Tests_TCAP: Fix ipa_to_ipa testcase

tcap routing doesn't work the way the test thinks. E.g. a Begin can't be
routed to a special destination because it does't contain a dtid which
is needed to route to the correct ASP.

STP_Tests_TCAP: Test routing of fragments in TC_tcap_loadshare_ipa_tcap_range_success_pc

A TCAP Begin will cause the stp to create a cache entry and route
according to that. Send only a TCAP Continue so we check the tcap range
routing logic.

bts: TC_pcu_interf_ind: check reporting interval instead of absolute FN

Recent osmo-bts commit 53f0ec29 broke TC_pcu_interf_ind:

  Verdict: fail reason: Odd TDMA frame number := 935

There's no requirement that periodic interference reports must land
on a TDMA frame number satisfying 'fn mod 104 == 0' - only that they
keep arriving every configured averaging period.  Instead, verify
that the interval between consecutive reports equals 104 TDMA frames
(1 SACCH period), using the new f_gsm_fn_sub() helper.

stp: for TCAP loadshare: use NI == national

Use a non-zero NI. The TCAP tests don't check it
on the receive path, but the osmo-stp is checking
it if it matches the configuration.

5gc: disable TC_handover_inter_ngran_xn for latest

Revert "bts: limit stderr logging to ERROR to avoid long write() to ext4 fs"

This reverts commit 3c798765f04dd7428c76e3c5cbf3f2ee27a0af4d.

Reducing logging verbosity did not help: we're still seeing the clock
skew errors and restarts.  This makes debugging harder, and is not
relevant anymore because we've switched to tmpfs [1].

stp: tcap-loadshare: add TC_tcap_loadshare_m3ua_to_ipa_udts

If a TCAP message arrives which is:
* not a TCAP Begin or Abort (e.g. a TCAP Continue)
* not in the TCAP session cache/tracking
* not have a dTID for a registered TCAP Add Range

The tcap load-share will reject this message with a UDTS

CCID: Check if reader accepts highest P3 value 0xff

This test should ensure that there is no buffer overflow when receiving
large responses from SIM.

Change-Id: I298795d791f2964758bd4792e10131f92cf561bc

CCID: Check if reader handles special P3 value 0x00 correctly

If data is requested from SIM with P3 set 0x00, it means that 256
bytes are requested. The reader will receive a procedure byte, which
must cause it to receive all 256 data bytes + two status words.

Change-Id: Icc3fd1937b9829fcf825c58d7b676aa2be2c48e7

CCID: Check if reader restarts WWT upon NULL procedure byte

The reader will receive a NULL procedure byte every 0.2 for a long time.
The reader may only respond with a status that time extension was
requested. At the end the SIM proceeds with a valid response. This
response must be returned by the reader.

SIMTRACE: Increase USB receive buffer size

The maximum SIM request data can be 255 bytes. Additionally, the
SIMtrace PDU header is 14 bytes. So increase the buffer to 269 bytes.

CCID: Check if reader sends request TPDU with maximum size

The maximum size of a request TPDU can have 5 bytes header and 255 bytes
data. It is expected that the reader transmits all bytes to SIM without
failure.

Change-Id: I7c1cb52b578c19d6c0ec1493e45f6ed9c43735b4

CCID: Check response of reader with empty SIM carrier

The reader has a SIM carrier inserted, but there is no response from the
SIM while expecting the ATR. The reader will get a timeout and is
expected to respond with a suitable error code.

The test uses the slot with the SIMtrace inserted. The SIMtrace will not
respond with an ATR. This way there is no (extra) empty slot required
for this test.

CCID: Add testenv.cfg to run tests using testenv

Change-Id: I97c9da414facf438aa28d5200c4152730ff763a2

CCID: Check if reader times out while expecting status words

A case 1 APDU is sent toward the reader. The reader expects two status
words. If none of these are sent by the SIM the reader must timeout and
send an error message back to the host.
