ovpn_peer_vp...dr_conflict6(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so bestie, this page is from the Kernel API Manual (section 9, kernel-space functions only, we're fancy like that ✨) and it's all about ovpn_peer_vpn_addr_conflict6 — the little function that checks whether a VPN v6 address is already being used by somebody else. no cap, that's the whole job 🎀

✨ SYNOPSIS ✨

bool ovpn_peer_vpn_addr_conflict6 (struct ovpn_priv *ovpn , const struct ovpn_peer *peer , const struct in6_addr *addr );

🦋 ARGUMENTS 🦋

  • ovpn — the openvpn instance we're snooping around in 🔍
  • peer — the peer that's being added or updated, or NULL (yes, NULL is a whole vibe here, it's allowed)
  • addr — the VPN IPv6 address we wanna check, bestie 💖

🌸 DESCRIPTION 🌸

so basically, this function checks whether addr is already assigned to another peer. like, is this address taken? because we do NOT do duplicates in this house 💅

the peer argument gets ignored when a match is found — which is literally the point, because it means peer updates can keep an existing address without the function throwing a fit 😌 slay.

and unspecified addresses? ignored. not our problem, not our drama 🙈

👑 NOTE 👑

okay bestie this one's important: the caller must hold ovpn->lock. like, no lock, no service. don't come for this function without it, fr fr 🔒

⭐ RETURN ⭐

  • true on conflict 🔥 (the address is taken, oops)
  • false otherwise 🧚 (you're good, go off)
