📦 version 7.3.1, in nixpkgs unstable

💅 cipso_v4_doi_getdef(9) — it's giving "find me a valid DOI definition" ✨

okay so bestie, buckle up, this one's from the Kernel API Manual and it's lowkey a little baddie of a function 🎀

🌸 NAME 🌸

cipso_v4_doi_getdef — returns a reference to a valid DOI definition 🫶

⭐ SYNOPSIS ⭐

struct cipso_v4_doi * cipso_v4_doi_getdef (u32 doi );

like, that's the whole vibe. one arg, one pointer back 💖

🦋 ARGUMENTS 🦋

  • doi — the DOI value 💅 that's it, that's the whole argument, she's simple and she knows it

👑 DESCRIPTION 👑

so what she does is: she searches for a valid DOI definition, and if one is found, it gets returned to the caller. slay. if not? you get NULL back. sorry bestie 😭

🚨 IMPORTANT, no cap — the caller must make sure that rcu_read_lock is held while accessing the returned definition. and when the caller is done, the DOI definition reference count is decremented. don't forget that part, i'm literally begging 🙏

🌈 SEE ALSO 🌈

Kernel file ./net/ipv4/cipso_ipv4.c — and honestly, the whole friend group shows up here, so let's give them all their moment ✨

and that's the whole page, bestie 🧚✨ this one's shipped from ./net/ipv4, dated October 2026 — go forth and hold that rcu_read_lock, ily, bye 💜🎀
