Patch Set 3: Code-Review+1 (3 comments) File include/osmocom/pfcp/pfcp_msg.h: https://gerrit.osmocom.org/c/osmo-upf/+/27631/comment/1d5c28ce_fe655651 PS3, Line 69: static inline uint32_t osmo_pfcp_next_seq(uint32_t *seq_state) I would expect no constraint whatsoevre on the starting / initial value of the sequence number. Basically every command must have a unique serial number so we can match responses to requests, and the receiver can distinguish re-transmission of a command (same seq) from a new command (different seq) https://gerrit.osmocom.org/c/osmo-upf/+/27631/comment/ca80ed75_e149434f PS3, Line 72: (*seq_state) &= 0xffffff; the interesting question is why we use a uint32_t variable if we only use 16 bits of it? https://gerrit.osmocom.org/c/osmo-upf/+/27631/comment/f78a1104_ebf16f72 PS3, Line 110: struct osmo_fsm_inst *peer_fi; peers and sessins are orthogonal concepts, why do you think a message is only either part of a session or related to a peer? shouldn't it be both at the same time? -- To view, visit https://gerrit.osmocom.org/c/osmo-upf/+/27631 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-upf Gerrit-Branch: master Gerrit-Change-Id: I3f85ea052a6b7c064244a8093777e53a47c8c61e Gerrit-Change-Number: 27631 Gerrit-PatchSet: 3 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-CC: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-CC: pespin <pespin(a)sysmocom.de> Gerrit-Attention: neels <nhofmeyr(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Tue, 05 Apr 2022 13:24:47 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment
