🌸 ovpn_peer_vp...dr_conflict4(9) 💅

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, yes it's fancy, we stay fancy here ✨ this one's a lil' helper from the OpenVPN kernel crew and it's genuinely so simple you're gonna slay it.

✨ NAME ✨

ovpn_peer_vpn_addr_conflict4 — the vibe check that tells you if a VPN v4 address is already taken 👀 like, is somebody else sitting in your seat, or are you good?

🦋 SYNOPSIS 🦋

bool ovpn_peer_vpn_addr_conflict4 (struct ovpn_priv *ovpn , const struct
ovpn_peer *peer , const struct in_addr *addr );

🎀 ARGUMENTS 🎀

  • ovpn — the openvpn instance you're searching through 🔍 like scrolling the group chat for a specific message.
  • peer — the peer that's being added or updated, or NULL if there's no peer in the picture 🙈 yes NULL is allowed, it's fine, we don't judge.
  • addr — the VPN IPv4 address you wanna check 💖 the one you're side-eyeing.

💜 DESCRIPTION 💜

So here's the tea, bestie: this function checks whether addr is already assigned to another peer. That's it. That's the whole job. 🫶

And when a match is found, peer gets ignored — which is literally the point, because it means you can do peer updates that keep an existing address without the function throwing hands at you. Iconic behaviour, honestly. 👑

Also: unspecified addresses are ignored. Not our problem, not today. 💀

⚠️ NOTE ⚠️

the caller must hold ovpn->lock.

Not optional, not a suggestion, not a "maybe later" — the caller must hold ovpn->lock. Lock it or block it, babes. 🔒

⭐ RETURN ⭐

true on conflict, false otherwise. Boom. Binary. Periodt. 💅
