💅 smk_copy_rules(9) — Kernel API Manual

okay so bestie, welcome to the kernel API manual ✨ this one's a lil function called smk_copy_rules, and honestly? the name ate. it literally copies a rule set. that's it. that's the vibe 🎀

🌸 NAME 🌸

smk_copy_rules — copy a rule set 💖

✨ SYNOPSIS ✨

int smk_copy_rules (struct list_head *nhead , struct list_head *ohead ,
gfp_t gfp );

like look at her. three params, one int, zero drama 🫶

🦋 ARGUMENTS 🦋

  • nhead — the new rules header pointer 👑 this is where the copied ruleset is headed, main character destination fr
  • ohead — the old rules header pointer 🌸 this is the og ruleset, the one getting copied from, respect her legacy
  • gfp — the type of the memory for the allocation 🧚 like which memory flags you're allocating with, iykyk

💜 DESCRIPTION 💜

Returns 0 on success, -ENOMEM on error 😭

that's the whole description. no cap. she's short, she's sweet, she's giving minimalist icon. if it works you get a lil 0, and if the memory allocation falls through you get -ENOMEM and a vibe check failure 💀

🔥 SEE ALSO 🔥

okay so this is the part where the manpage goes absolutely feral — the reference list is huge and we are NOT skipping a single one, bestie 💅 all in the kernel file ./security/smack/smack_lsm.c:

like?? that's the whole friend group showing up to the function's birthday party 🎂 every single one of them, no gatekeeping 💖

💀 real talk though: the description only promises 0 on success and -ENOMEM on error — don't be out here inventing extra return codes, bestie. that's the documented lore, periodt.

okay that's the page!! and for the cute sign-off: this lil beauty lives under the source dir ./security/smack, and it's dated October 2026 🦋 so mark your calendars, she's a future icon 👑✨ love that for her, and love that for you for reading this far 🫶💜
