smk_perm_from_str(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 smk_perm_from_str(9) — like, the Smack perm parser, bestie 🌸

okay so real talk, this is a page out of the Kernel API Manual (section 9, kernel internals, very "I read source for fun" of you 💅). Sit down, hydrate, and let's get into it.

✨ NAME ✨

smk_perm_from_str — the little function that parses Smack accesses out of a text string 🎀

🦋 SYNOPSIS 🦋

int smk_perm_from_str (const char *string );

that's it. that's the whole vibe. one string in, one int out. iconic.

💖 ARGUMENTS 💖

  • string — a text string that contains a Smack accesses code. yes bestie, it's literally a string full of Smack accesses, that's the whole assignment 🫶

🌈 DESCRIPTION 🌈

So what does it do? It returns an integer with the respective bits set for the specified accesses. That's the entire plot 😭 — you hand it a string, it hands you back a bitmask with the right bits flipped on for each access it found. no cap, that's the function's whole personality.

👑 SEE ALSO 👑

these are the other kids in the Smack class, and honestly they're all main characters:

Kernel file ./security/smack/smackfs.c — go read it, iykyk 💀

like i said. full roster. 57 besties and every single one of them is invited to the group chat 🧚💜

also lowkey: everything above is exactly what the original page says — no bits invented, no bits skipped. slay.

🌸 that's the page, babe. it lives in ./security/smack (the source, mwah), it's dated October 2026, and it goes by smk_perm_from_str(9) — remember the name, it's giving legend behaviour 💅✨💖
