( https://gerrit.osmocom.org/c/osmo-sgsn/+/15167 ) Change subject: gprs_gmm: Introduce assert to guard against unexpected condition ...................................................................... Patch Set 2: (1 comment) https://gerrit.osmocom.org/#/c/15167/2/src/gprs/gprs_gmm.c File src/gprs/gprs_gmm.c: https://gerrit.osmocom.org/#/c/15167/2/src/gprs/gprs_gmm.c@1747 PS2, Line 1747: mmctx->ran_type == MM_CTX_T_GERAN_Gb > I'm also confused. […] This is an assert I add to try to catch keith's osmo-sgsn isntance crashing (we started debugging it in OsmoDevCon). I don't want to directly workaround the issue, I really want osmo-sgsn to assert and exit in this situation, so we can make sure this is the condition he's hitting. Since lots of subscribers are using the sgsn at that time, it's impossible otherwise to find out. Killing osmo-sgsn here is not a big issue since anyway it would crash later on due to the bug we spotted. Regarding the assert condition: If ran_type is MM_CTX_T_UTRAN_Iu, it's perfectly fine to have a null llme, so I really want to check in the Gb case (because anyway that's what's deployed in the setup where we saw the crash). I want to make sure that "it doesn't happen that llme is NULL when on Gb", and the condition expresses so. The expression I'm using is exactly the same you are proposing. But Ok, I'll change it if you think it's simpler. -- To view, visit https://gerrit.osmocom.org/c/osmo-sgsn/+/15167 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-sgsn Gerrit-Branch: master Gerrit-Change-Id: I8e1eaeb9b3ebee8e45704b4fe007190c7db609e4 Gerrit-Change-Number: 15167 Gerrit-PatchSet: 2 Gerrit-Owner: pespin <pespin at sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge at gnumonks.org> Gerrit-Reviewer: lynxis lazus <lynxis at fe80.eu> Gerrit-Reviewer: neels <nhofmeyr at sysmocom.de> Gerrit-Reviewer: pespin <pespin at sysmocom.de> Gerrit-CC: fixeria <axilirator at gmail.com> Gerrit-Comment-Date: Thu, 15 Aug 2019 09:16:49 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: fixeria <axilirator at gmail.com> Comment-In-Reply-To: neels <nhofmeyr at sysmocom.de> Gerrit-MessageType: comment -------------- next part -------------- An HTML attachment was scrubbed...
