Patch Set 3: (7 comments) File include/osmocom/pfcp/pfcp_msg.h: https://gerrit.osmocom.org/c/osmo-upf/+/27631/comment/9bd8f6d3_249ab9dd PS3, Line 44: #define OSMO_LOG_PFCP_MSG_SRC(M, LEVEL, file, line, FMT, ARGS...) do { \ This starts to look as too much for a macro imho, it may make sense to move it to a variadic function https://gerrit.osmocom.org/c/osmo-upf/+/27631/comment/c6227464_17a86ef5 PS3, Line 69: static inline uint32_t osmo_pfcp_next_seq(uint32_t *seq_state) This function will return 1 on first call most probably. Are you sure that's accepted per spec? or it needs to starts with 0? https://gerrit.osmocom.org/c/osmo-upf/+/27631/comment/2d00fcc1_188ddd66 PS3, Line 110: struct osmo_fsm_inst *peer_fi; Looks like these 2 groups can be in a union? https://gerrit.osmocom.org/c/osmo-upf/+/27631/comment/a4266ec8_93fcbdcb PS3, Line 123: #define OSMO_PFCP_MSG_FOR_IES(IES_P) ((struct osmo_pfcp_msg *)((char *)IES_P - offsetof(struct osmo_pfcp_msg, ies))) what's the meaning of FOR here? https://gerrit.osmocom.org/c/osmo-upf/+/27631/comment/6d8ae394_271aff96 PS3, Line 149: #define OSMO_PFCP_MSG_MEMB(M, OFS) ((OFS) <= 0 ? NULL : (void *)((uint8_t *)(M) + OFS)) write it as a static inline, where you can set type of OFS to unsigned, you can then drop the first check. Or you reall expect to pass -1 to it?
