Patch Set 1: Code-Review+1 (1 comment) File msc/MSC_Tests.ttcn: https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/28048/comment/d331b9d8_bd64… PS1, Line 6815: BSSAP.send(ts_PDU_DTAP_MO(ts_CM_SERV_REQ(CM_TYPE_MO_SMS, mi))); I am trying to understand the TC scenario. Above in f_perform_lu() it's performing the Location Updating procedure with IMSI=...99. Then here it's establishing a new connection and sending a CM Service Request with IMSI=...99999, right? So IMSI=...99999 is unknown to the MSC/VLR and has no relation to the IMSI=...99 that was used in Location Updating. And somehow an unknown IMSI in CM Service Request causes a segfault. Do we really need to perform LU with a different IMSI? -- To view, visit https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/28048 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-ttcn3-hacks Gerrit-Branch: master Gerrit-Change-Id: I3f84d00f456aaee578787059d7010c25efcdcf56 Gerrit-Change-Number: 28048 Gerrit-PatchSet: 1 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: neels <nhofmeyr(a)sysmocom.de> Gerrit-Comment-Date: Thu, 05 May 2022 10:54:59 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Gerrit-MessageType: comment
