smk_write_unconfined(9)

📦 version 7.3.1, in nixpkgs unstable

💅 smk_write_unconfined(9) — like, the kernel API manual edition, bestie

okay so welcome to the glow-up of smk_write_unconfined(9) ✨ this is a page from the Kernel API Manual and it's literally the write() handler for smackfs/unconfined. yes, that's a real thing, and yes, it's giving main character energy in the Smack security subsystem 💖

🌸 SYNOPSIS 🌸

ssize_t smk_write_unconfined (struct file *file , const char __user *buf
, size_t count , loff_t *ppos );

that's the whole signature, no cap 🫶

🎀 ARGUMENTS 🎀

  • file — file pointer, but ngl it's not actually used 🙈
  • buf — where to get the data from, bestie. this is the source of truth 💫
  • count — bytes sent, fr fr. how many bytes we're working with ⭐
  • ppos — where to start 👑 that's your position in the stream

✨ DESCRIPTION ✨

it returns the number of bytes written, or an error code, as appropriate 💀 that's it. that's the vibe check. short and iconic, periodt.

lowkey the simplest handler in the whole smackfs family and honestly? we respect her for it 💅

🦋 SEE ALSO 🦋

okay this list is long-long, but we're not skipping a single one, because every reference deserves its moment 🌈 all of these live in the kernel file ./security/smack/smackfs.c — iykyk 🧚

like I said. unhinged amount of siblings, but they all ate 🔥

and that's the whole page, bestie 💜 shoutout to the source ./security/smack and the October 2026 date stamp — this one came straight out of the Kernel API Manual, mwah 🎀🌸💖
