pespin gerrit-no-reply at lists.osmocom.orgpespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/16016 ) Change subject: sgsn: Introduce test TC_attach_req_id_req_ra_update ...................................................................... sgsn: Introduce test TC_attach_req_id_req_ra_update The scenario in this test triggers a crash in osmo-sgsn fixed by osmo-sgsn.git I64fa5cf1b427d3abb99e553e584897261a827ce6. With that osmo-sgsn patch applied, the process doesn't crash anymore but the test still fails due to an XID message being sent with a new yet-not-seen-by-ttcn3 TLLI and as a result TTCN3 BSSGP_Emulation fails: BSSGP_Emulation.ttcn:390 setverdict(fail): none -> fail reason: "Couldn't find Component for TLLI 'FE791757'O", new component reason: "Couldn't find Component for TLLI 'FE791757'O" Other than that, the test runs fine. It still needs to be clarified whether the new TLLI sent by osmo-sgsn is expected and test needs to be fixed, or whether it's an sgsn bug.
