[M] Change in osmo-ttcn3-hacks[master]: msc: fix f_tc_ho_inter_bsc0(): properly patch n_sd
by fixeria 27 Mar '24

27 Mar '24

fixeria has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/36467?usp=email ) Change subject: msc: fix f_tc_ho_inter_bsc0(): properly patch n_sd ...................................................................... msc: fix f_tc_ho_inter_bsc0(): properly patch n_sd Assuming n_sd should be 3 is only valid for non-A5 testcases, in which we are *not* doing ciphering and authentication. For the A5 testcases (TC_ho_inter_bsc_a5_*), this assumption is incorrect and osmo-msc is definitely not happy about that: Duplicate DTAP: bin=0, expected n_sd == 0, got 3 (ran_msg.c:159) Dropping duplicate message ... (msc_a.c:1363) Why and how the A5 testcases passed so far? It was a pure luck, which sailed away when we started executing ttcn3-msc-test with io_uring. The A5 testcases were passing thanks to the as_optional_cc_rel() that gets activate()d in background before calling f_call_hangup(). This altstep does not have the 'repeat' statement, and as a side effect it may cancel any normal alt-statements and even standalone receive() statements. In the successful scenario, it would cancel (unblock) the following receive operation in f_call_hangup(): MNCC.receive(tr_MNCC_REL_ind(cpars.mncc_callref)); log("f_call_hangup 2: rx MNCC REL ind"); BSSAP.receive(tr_PDU_DTAP_MT(tr_ML3_MT_CC_REL_COMPL(cpars.transaction_id))); // ^^^^^^^^^^ as_optional_cc_rel() triggers here and cancels this one which is a pure luck because our CC RELEASE was sent with incorrect sequence number and got dropped, so osmo-msc would never send us CC RELEASE COMPLETE. It would instead send us CC RELEASE due to expire of T306, and the as_optional_cc_rel() would kick in handling this message and responding with CC RELEASE COMPLETE. In the failing scenario though (when running with io_uring), that same altstep running in backround may trigger *earlier* and unblock another standalone receive() statement: MNCC.receive(tr_MNCC_REL_ind(cpars.mncc_callref)); // ^^^^^^^^^ as_optional_cc_rel() triggers here and cancels this one log("f_call_hangup 2: rx MNCC REL ind"); BSSAP.receive(tr_PDU_DTAP_MT(tr_ML3_MT_CC_REL_COMPL(cpars.transaction_id))); so that we will be stuck waiting for CC RELEASE COMPLETE until the Tguard expires. This patch fixes n_sd patching, so that our CC RELEASE message is handled properly and the call gets released as expected, without requiring as_optional_cc_rel() to kick in. The missing 'repeat' is to be added to as_optional_cc_rel() in a follow-up patch.
