tipc_udp_enable(9)

💅 tipc_udp_enable(9) — from the Kernel API Manual bestie ✨

okay so real talk, this is a section 9 kernel API page and it's lowkey the glow-up moment where a brand-new UDP bearer gets born into the world 🎀

✨ NAME ✨

tipc_udp_enable — the callback that creates a new udp bearer instance 🦋

🌸 SYNOPSIS 🌸

int tipc_udp_enable (struct net *net , struct tipc_bearer *b , struct nlattr *attrs[] );

yep that's the whole signature, no cap, copy it exactly 💅

💖 ARGUMENTS 💖

• net — the network namespace we're living in, main character energy 🌈
• b — a pointer to the generic tipc_bearer, aka the plain-Jane bearer struct before the udp glow-up 🫶
• attrs — the netlink bearer configuration, literally all the settings slid across the netlink wire 📨

🧚 DESCRIPTION 🧚

so what does it do, bestie? two things, and they're both important:

1. validate the bearer parameters — vibe check first, no sketchy config gets through 🙈
2. initialize the udp bearer — and then we actually set the thing up ✨

⚠️ big one: rtnl_lock should be held. like, genuinely. this is not a drill, hold the lock 🔒💀

🔥 SEE ALSO 🔥

• Kernel file ./net/tipc/udp_media.c — the source, go read it, iykyk 📖
• struct udp_media_addr(9) 🍓
• struct udp_bearer(9) 🎀
• tipc_parse_udp_addr(9) ⭐

okay that's the whole page, you ate that 🫶💜 and for the record this little beauty lives in ./net/tipc and the version stamp on it says October 2026 — so yes, iconic, timestamped, and filed under tipc_udp_enable(9) forever 👑✨
