Patch Set 6: (1 comment) File sgsn/SGSN_Tests.ttcn: https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/36601/comment/68b78d5c_0321… PS6, Line 3748: f_pdp_ctx_act(apars); I believe PCAPs would do a better job explaining what's going on. https://osmocom.org/attachments/download/8165/SGSN_Tests.TC_sgsn_context_re… -- here is a PCAP file recorded with the previous patch revision (5). * [packet 456] MS sends GMM `Activate PDP Context Request` with the `Requested PDP Address` IE being empty (wireshark displays `Dynamic addressing`); * [packet 476] SGSN sends GTPC `Create PDP Context Request` with the `End user address` IE being empty (expecting GGSN to assign it?); * [packet 478] GGSN (the testsuite) responds with `Create PDP Context Response`, but **not including** the `End user address` IE; * [packet 487] SGSN responds with GMM `Activate PDP Context Accept` with the `PDP Address` IE being empty (wireshark displays `Dynamic addressing`); * [packet 489] the testsuite sends `SGSN Context Request`; * [packet 492] SGSN responds with `SGSN Context Response` containing no `PDP Context` IE -- this makes the testcase fail. This is basically a), `apars.addr.addressInfo := omit` by default. This is also the case for the other (existing) testcases in SGSN_Tests.ttcn, see https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-sgsn-test/2318/art… for instance. Or any other `SGSN_Tests.TC_attach_pdp_act_...` testcase. The testsuite (virtual GGSN) assigns no IP address, and osmo-sgsn happily accepts that. I don't know if this is right or wrong, you're saying it's not right? -- To view, visit https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/36601?usp=email 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: I965c0200ea380c55dc0cd8d3f8e5110883ce2646 Gerrit-Change-Number: 36601 Gerrit-PatchSet: 6 Gerrit-Owner: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: osmith <osmith(a)sysmocom.de> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-CC: daniel <dwillmann(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Attention: daniel <dwillmann(a)sysmocom.de> Gerrit-Comment-Date: Mon, 22 Apr 2024 13:04:38 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: laforge <laforge(a)osmocom.org> Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Comment-In-Reply-To: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-MessageType: comment
