2020-06-14bsc: allow multiple MSCsNeels Hofmeyr3-75/+119
Similar to the MSC tests, have several g_bssap and mp_bssap_cfg. Prepare for MSC pool tests. Replace g_bssap with a g_bssap[NUM_MSC] array. Replace mp_bssap_cfg with an mp_bssap_cfg[NUM_MSC] array. Requires patch I1986e4ef43beee161c82193694421b56136c1afe in docker-playground to match the new required BSC_Tests.cfg format. Related: OS#3682 Change-Id: Ibb36695b7c31f7b04eec6c5d59522fc0779b3c2f

2020-06-14fix f_enc_IMEI_L3() oddevenIndicatorNeels Hofmeyr1-5/+14
f_gen_imei() calls f_enc_IMEI_L3() with a 14 digits argument, but the IMEI_L3 template used is hardcoded to 15 digits. So the oddevenIndicator must always indicate odd, not depend on the digits argument. f_gen_imei() should probably also compose a Luhn checksum, leaving that to another patch. Found by using the new osmo_mobile_identity API in osmo-msc, which is stricter about odd/even and filler digits than our previous implementations. See osmo-msc Idfc8e576e10756aeaacf5569f6178068313eb7ea . Change-Id: Iaa9ba1214c4c15fd9620e68fe2e842fdf52912c0

2020-06-09library/RSL_Emulation: optional IPA stream ID patchingVadim Yanitskiy1-0/+25
Unfortunately, the latest release of osmo-bts still has a bug, that has been fixed [1] in the recent master. Because of that, most of the test cases in ttcn3-bts-test-latest currently fail. The problem is that all transceivers use IPAC_PROTO_RSL_TRX0, regardless of what the BSC tells them to use. Let's work this around by patching IPA stream ID in ASP_RSL_Unitdata messages coming from the IPA emulation.

2020-06-09bts: Introduce test TC_tx_power_start_ramp_up_bcchPau Espin Pedrol3-3/+82
This test verifies power ramping (up) is working fine during BTS startup. config files are updated to make sense: * "nominal power" in osmo-bsc.cfg reflects correct default nominal tx power of fake_trx. * "osmotrx tx-attenuation" in osmo-bts.cfg is removed to let osmo-bts use the value received through OML (max_power_red 20). * "power-ramp step-size" in osmo-bts.cfg is increased to speed up the test. There's no good reason to keep it lower. Change-Id: Ieb7444c6312bbeab64da2732393b3facf3e1f003

2020-06-02MGCP_Test: fix test vector in TC_amr_oa_bwe_rtp_conversionPhilipp Maier1-1/+5
The rtp payload test vector in TC_amr_oa_bwe_rtp_conversion is wrong, it lacks the last byte which should be 0x00. Also the testvector is not very well chossen since it after BWE conversion the actual payload does not shrink (even if it looks like if it would because of the 0x00 byte at the end). Lets pick a better payload from a real world trace that actually shrinks by one byte when it is converted to BWE and use that one. Change-Id: Id4256049bbca49ad5c2eb0579128838ebae062f8

2020-05-29PCU: revert changes to f_TC_egprs_pkt_chan_req(), fix testsVadim Yanitskiy1-17/+5
I noticed that TC_egprs_pkt_chan_req_reject_exhaustion has started to fail since the refactoring change [1]. As it turned out, this test case does not init a GprsMs instance, which is needed by a function it depends on - f_TC_egprs_pkt_chan_req(). I don't really see the point of using the GprsMs abstraction for such small test cases sending just a few messages, which do not require us to keep any state. Let's just revert those changes, and keep using the low level API. [1] Ib3fee37580f0ea0530a659dec83656799bf57288 Change-Id: I4f32c138e7587e68d2d35d13d13c044893fec4b2

2020-05-28fixup pcu/GPRS_Components: do not duplicate existing functionsVadim Yanitskiy2-72/+14
Both f_ms_rx_imm_ass_ccch() and f_ms_establish_ul_tbf() functions are actually twin brothers of good old f_pcuif_rx_imm_ass() and f_establish_tbf() with some minor changes. The former accepts a GprsMS parameter, that is never used. The latter simply calls f_ultbf_new_from_rr_imm_ass() in the end. Let's avoid code duplication: - call f_establish_tbf() from f_ms_establish_ul_tbf(), - remove f_ms_rx_imm_ass_ccch(), use f_pcuif_rx_imm_ass(). After the removal of f_ms_rx_imm_ass_ccch(), the implementation of TC_ta_idle_dl_tbf_ass() does not need the GprsMS state, so let's make it look like it was before.

2020-05-28pcu: Refactor GPRS infrastructure to keep state and simplify testsPau Espin Pedrol2-564/+633
Before this patch, each test had to somehow keep state for all the transactions needed. Now, most of the state is moved to generic GprsMS, UlTbf and DlTbf structures, and APIs to maintain its state, as well as function helpers to submit or receive messages from it. For now specially the Tx side was improved, some of the Rx parts are left for later and are still using the old APIs. This will allow for more complex scenarios and more complex tests running several MS. All the tests were updated to use the new APIs, reworked when needed and even totally rewritten in some cases since they were doing inconsistent/wrong stuff from the point of view of what the scenarios or code paths they were expected to test. There's no test regressions. Change-Id: Ib3fee37580f0ea0530a659dec83656799bf57288

2020-05-26library/RSL_Emulation: server mode: handle multiple transceiversVadim Yanitskiy3-6/+126
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.

2020-05-26library/IPA_Emulation: handle optional conn_id in ASP_RSL_UnitdataVadim Yanitskiy1-8/+19
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.

2020-05-26library/IPA_Emulation: server mode: handle multiple client connectionsVadim Yanitskiy1-41/+74
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.
