💅 security_path_mknod(9) — Kernel API Manual ✨

okay so bestie, welcome to the manual page for security_path_mknod, straight outta the Kernel API Manual (that's the manual name, section 9, we love a numbered era) 🎀 this one's short and sweet and honestly kind of a whole vibe — it's the hook that vibes-checks whether you're allowed to make a special file. let's get into it 🦋

✨ NAME ✨

security_path_mknod — check if creating a special file is allowed 👑

🌸 SYNOPSIS 🌸

int security_path_mknod (const struct path *dir , struct dentry *dentry
, umode_t mode , unsigned int dev );

no cap, that's the whole signature — type it exactly like that, backticks and all 💅

🎀 ARGUMENTS 🎀

  • dir — the parent directory, aka where this whole situation is going down 📁
  • dentry — the new file itself, the main character 🦋
  • mode — the new file's mode 🫶
  • dev — the device number 🔢

💖 DESCRIPTION 💖

So the tea is: this hook checks permissions when a file is being created. 🧚

⚠️ and here's the part where you gotta listen, bestie — this hook gets called even if the mknod operation is being done for a regular file. like, yes, even then. don't come for me, that's literally what the page says 😭

⭐ RETURN ⭐

Returns 0 if permission is granted. that's it, that's the return. slay ✅

🌈 SEE ALSO 🌈

okay this next part is a moment — the kernel file is ./security/security.c, and then there's a whole friend group of functions. every single one, in order, no one left behind 💜

and that's the whole page, bestie 🫶 iykyk. this one's from the source tree at <pink>./security</pink>, dated October 2026 — mwah, go check your permissions, ily, bye 💖✨🎀
