2022-05-03remsim: server: TC_connect_{client,bankd}_duplicateHarald Welte2-0/+85
Add two new tests for the remsim-server, which simulate what happens if a client or bankd with identical ID connects twice. We expect the second connection to get rejected at RSPRO level, and to be closed. Change-Id: I29023f6b5ba430338c77bf01508c81bd6d8c99fa Ralated: OS#5527
2022-05-03bsc: Fix dangling subscriber talloc ctx in f_TC_paging_NreqPau Espin Pedrol1-1/+6
First, page only on BTS0, not all the BTS. This simplifies the test and also makes the subscriber be refcounted only on BTS0. Then, drop the OML connection after receiving all the expected paging requests; it will make the BSC flush the paging queue and hence avoid TTCN3 checks erroring due to dangling subscriber talloc contexts.

2022-05-03BTS_Tests: workaround addr='0.0.0.0' in f_rtpem_activate()Vadim Yanitskiy1-8/+20
If a CRXC message contains optional remote IP and port IEs, the CRCX ACK received from the BTS is expected to contain its listen address and port. In some cases osmo-bts may indicate nonsense addr='0.0.0.0', and indeed the RTP_Emulation component is not gonna like this. This makes both BTS_Tests.TC_speech_rtp_tch[fh] test cases fail whenever executed in Docker: Connection refused (unexpected) Let's work this around by sending the remote IP and port IEs in additional MDCX message and omitting them in CRCX. This mimics osmo-bsc's behavior and makes both test cases pass. Change-Id: I03453e72f62819989dfe6aa12d8bd889fced1046 Related: OS#5242

2022-04-30bts/osmo-bts.cfg: reduce OML logging verbosity, degrade to noticeVadim Yanitskiy1-1/+0
Average size of osmo-bts.log after running ttcn3-bts-test is ~178 MB, and more than 52% (!) of it is the OML logging messages. Other than making the logfile bigger, bursts of OML messages make it really hard to follow the output of osmo-bts when running tests natively. Change-Id: Ib5346a3ca42917169e195f905472ccea7579e5eb

A more clear reading of TS 48.049 is that the KILL COMPLETE should *only* contain a Cell List IE if it relates to an Emergency message; only the Number of Broadcasts Completed IE indicates successful cells. osmo-bsc fixes this in I9a43d386da01f085663d231a555b8b5acc99faca Change-Id: Ia50e50f9812d9934d35d32b25e1079240df04a82 Related: SYS#5906

2022-04-26bsc: TC_paging_500req: Validate initial transmissions have higher prioPau Espin Pedrol1-0/+3
After osmo-bsc Change-Id I1ae6d97152c458247bc538233b97c2d245196359, initial requests are prioritized over retransmits. Before that feature was in place, when sending 500 requests in this test to the BSC, it could happen that the paging scheduler triggered (every 500ms) before all the 500 requests were received at the BSC. As a result, the scheduler would put some requests to the end of the queue after sending an initial request for it towards the BTS. If later more requests where received from TTCN3, they'd be put at the end, after the retransmissions. As a result, the emulated BTS would in general receive retranmits for the first bunch of requests before receiving the initial transmit of the later requests. Ths is no longer the case since the osmo-bsc is prioritizing now the initial requests. Hence, we'll only start receiving retransmits after all the new paging requests are received.

2022-04-15bsc: Expect number-of-broadcadsts-completed-list in CBSP KILL COMPLETEHarald Welte1-5/+11
When responding to a CBSP KILL with a CBSP KILL COMPLETE, make sure we include the optional "Number of Broadcasts Completed List" IE in order to inform the CBC about how many times the just-killed message had been broadcast before it was killed. It seems some CBCs expect this IE to be present, while 3GPP TS 48.049 lists it as optional. osmo-bsc is including this IE as of Change-Id I47aebd613dfc6dd9261ea9019a51aff0cd6470d8 This change updates the test suite to expect this IE to be included.

2022-04-12Avoid generating zero-length packetsHarald Welte7-19/+29
I used the construct like f_rnd_octstring(f_rnd_int(100)) in a number of places to generate random-length packets with randomized length. The problem I didn't realize is that f_rnd_int() of course can also return '0', which would generate zero-length packets. This may be permitted in some protocols, but it leads to problems e.g. when trying to send a UDP packet of zero length (which the kernel will not do). So let's introduce * f_rnd_int_nonzero() for returning non-zero randomized integers * f_rnd_octstring_rnd_len() for returning a random-length random payload octet string * replace all f_rnd_octstring(f_rnd_int()) call sites with the new function.

(It is not clear to me why only the SCCPlite tests show the fallout, the AoIP should be similarly affected, but isn't.) The failures were introduced by recent merge of I0633f60f09d58802f6be0238ef41a632d93a4327, which made as_Media() stricter by failing on early DLCX.

as_Media_mgw() is used to establish a voice stream. If a DLCX happens as part of that, that should be flagged as a problem. In fact the Mode Modify test with current osmo-bsc does exhibit a DLCX right upon the Assignment Complete message, which is a bug fixed in I5ab10ee7fd9c5d7608e8a06893881d990943feed. This patch now correctly flags this as a failure. In the two tests TC_ho_in_fail_no_detect, TC_ho_in_fail_no_detect2 the expected failure causes expected DLCX, so exempt those.
