2023-04-15pfcp_msg: refactor LOG_PFCP_MSGNeels Janosch Hofmeyr1-20/+5
It was requested during code review to make this a function and not a macro. One effective change: no longer log "NULL{fi=NULL}" when no m->ctx.session_fi or .peer_fi are set. Change-Id: Ic84090c9b1a34185577cfb2ea1efa9c07542df34
2022-07-23clarify osmo_pfcp_msg alloc APINeels Hofmeyr1-4/+4
Looking at the osmo_pfcp_msg_alloc API with a bit of distance now, I found that: - it is confusing to have a single function for req and resp. A resp may pass remote_addr as NULL, and a req may pass in_reply_to as NULL. Make this much more obvious with separate req/resp functions. - the osmo_pfcp_endpoint_tx() implicitly puts the local Node ID into sent PFCP messages, so the local_node_id arg for msg alloc is redundant. Drop that. Refactor without backwards compat, because we have not yet officially released this API. This requires a fixup patch to osmo-upf.git (and affects unmerged patches to osmo-hnbgw.git).
