It's not a problem when parsing a Packet Data Protocol Address IE, but may be a problem when encoding it with either `PDP_TYPE_N_IETF_IPv4` or `PDP_TYPE_N_IETF_IPv6`, because doing `msgb_put(msg, sizeof(struct gsm48_pdp_address))` is only valid for `PDP_TYPE_N_IETF_IPv4v6`. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/35625?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: I453ced42dd36df3a6ddb5db67093df5a22cad18c Gerrit-Change-Number: 35625 Gerrit-PatchSet: 1 Gerrit-Owner: pespin <pespin(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: lynxis lazus <lynxis(a)fe80.eu> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Attention: lynxis lazus <lynxis(a)fe80.eu> Gerrit-Comment-Date: Fri, 19 Jan 2024 22:09:07 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment
