Patch Set 2: (1 comment) File include/osmocom/hnbgw/hnbgw.h: https://gerrit.osmocom.org/c/osmo-hnbgw/+/28816/comment/6f1e3d4a_970dc740 PS2, Line 193: /* Return true when the user configured GTP mapping to be enabled, by configuring a PFCP link to a UPF. I we should not allow running osmo-hnbgw without proxying GTP through it (in detail, through its associated UPF). I am referring to the problem described for the need of a GTP-u proxy in the SGSN in OS#5154 and SYS#5389, SYS#5435. You also referenced a need for it in osmo-hnbgw in the decription of the task this commit is about (OS#5153). I think the main issue in this case would be what's described in SYS#5435 case "B]": "SGSN sending to nano3G GGSN's TEI which is changing after UpdatePDPCtxResp" but this time applied to HNBGW and hNodeB. -- To view, visit https://gerrit.osmocom.org/c/osmo-hnbgw/+/28816 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-hnbgw Gerrit-Branch: master Gerrit-Change-Id: Ic9bc30f322c4c6c6e82462d1da50cb15b336c63a Gerrit-Change-Number: 28816 Gerrit-PatchSet: 2 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-CC: laforge <laforge(a)osmocom.org> Gerrit-CC: pespin <pespin(a)sysmocom.de> Gerrit-Attention: neels <nhofmeyr(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Comment-Date: Thu, 28 Jul 2022 12:25:49 +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> Gerrit-MessageType: comment
