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.

Change-Id: I05261b4a754b4892955d0b4e426bd32be261efa7

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.

NGAP: UESecurityCapabilities is optional in PathSwitchRequestAcknowledge

Current master branch of Open5GS includes UESecurityCapabilities IE
in PathSwitchRequestAcknowledge, older versions do not. In order to
match message of all versions, replace the IE by an an asterisk.

CCID: Update titan.TestPorts.USB to current head

Update the USB test port dependency to include recent changes and
bugfixes that are required for further CCID tests.

Change-Id: I9dd769d2098822721f673b1293542fffa46542cc

CCID: Truncated APDU test

A SELECT APDU must have a header + two bytes of data (what to select).
The test truncates this APDU in all variants, ranging from 6 bytes down
to 0 bytes. The reader may respond with an error caused by invald
request or with and error caused by timeout of the SIM.

SIMTRACE: Add missing pres_pol to CardEmu_BD_Config message

Change-Id: I443e8151b0aa9bff150222ab6b507ed1f7946768

CCID: Integrate SIMTRACE emulation into test cases

This integration allows to add tests that use SIMtrace hardware instead
of a physical SIM. These tests can be used to test handling of invalid
behaviors, such as invalid responses or timeouts.

The number of slots (mp_use_slot_count) are reduced to 7, so that the
8th slot can be used with a SIMtrace for subsequent tests.

Change-Id: Ia27dd5198edb188bc73196ac3fbd6d56ba75812e

CCID: Add test to verify a working Simtrace setup

This test checks if a valid request is forwarded to SIMtrace and a
valid response is returned back to the reader.

Change-Id: I19264bc257024e9028996e417ff23bbbaebf5f92

CCID: Check if reader handles truncated SIM response

The reader knows how many byte of data is expected in the SIM response.
The emulated SIM will truncate that response, so that some data and the
final status words are not sent by the SIM. The tests expects the
reader to time out and return an appropriate error core.

testenv: fix podman_extra with multiple cfgs

Do not reuse the container that gets started to build the testsuite and
test components, to also do the the first testsuite run. Restart it
after selecting the current testenv*.cfg, and use the podman_extra value
from the right config instead.

As side-effect, this also makes the container restart logic much
simpler.

CCID: Check if parameters keep unchanged, if set without change.

Using SetParameters with the current set of parameter must not cause
them to change.

Change-Id: Id1bf5e58ba910d0633104b3bc3e902ce7d31cb10

CCID: Fix “unsupported Secure” test case

Expect SlotStatus or DataBlock. The specification states that DataBlock
response is used to indicate, if Secure command is not suppported.
Existing implementation, such as Omnikey Cardman 3121 or
osmo-ccid-firmware respond with SlotStatus instead.

CCID: Successful case 4 APDU test

A GET RESPONSE APDU must respond with the exact number of bytes that
have been indicated by SW2 of the previous SELECT MF APDU.

Change-Id: I88c5ad3285c025f584b1c0296095beb918ab3f4e

CCID: Successful case 1 APDU test

A MANAGE CHANNEL APDU has no data and must respond without any data,
just the status words.

Change-Id: I7d5ee9bbd8bb2505a762e3fd80238db658940c16

CCID: Successful case 2 and 3 APDU tests

A SELECT APDU has data and must respond without any data, just the
status words.

A READ BINARY APDU has no data, but it must respond with data, followed
by the status words.
