ovpn_nexthop_from_rt4(9)

💖 NAME 💖

okay bestie, this is the manual page for ovpn_nexthop_from_rt4(9) from the Kernel API Manual 💅 and it's literally the IPv4 nexthop-lookup helper you call when you need to know the nexthop for a given destination. lowkey iconic helper behavior, no cap ✨

---

✨ SYNOPSIS ✨

__be32 ovpn_nexthop_from_rt4 (struct ovpn_priv *ovpn , __be32 dest );

that's the whole signature, bestie — copy-paste exact and don't touch the spacing 🫶

---

🎀 ARGUMENTS 🎀

• ovpn — the private data representing the current VPN session, like the session's main-character data structure 💖
• dest — the destination to be looked up, aka the address we're trying to reach 👑

---

🌸 DESCRIPTION 🌸

so here's the tea ☕: this function looks up the IP of the nexthop in the IPv4 system routing table — the nexthop that should be used to reach the dest argument you passed in. it's giving "routing table, do your thing" energy ✨

and if no nexthop can be found? bestie, it just returns dest itself, because it probably has to be used as the nexthop. that's the whole fallback vibe, fr fr 😭💅

---

🔥 RETURN 🔥

the IP of the next hop if found 🔥 or dest itself otherwise 💅
