📦 version 7.3.1, in nixpkgs unstable

💅 smack_task_kill(9) — like, the Smack check on signal delivery, bestie

okay so welcome to smack_task_kill(9), straight out of the Kernel API Manual ✨ this is the page for the Smack check that happens when a signal is being delivered, and honestly it's a short one but she matters. no cap.

✨ NAME ✨

smack_task_kill — Smack check on signal delivery 🎀

like, when someone's trying to kill a task with a signal, Smack has opinions. that's the whole vibe.

🌸 SYNOPSIS 🌸

int smack_task_kill (struct task_struct *p , struct kernel_siginfo *info
, int sig , const struct cred *cred );

bestie. look at her. four whole arguments and she uses like... one and a half of them. iconic behaviour honestly 💅

🦋 ARGUMENTS 🦋

  • p — the task object. this is the main character fr, the task we're asking about.
  • info — unused. literally just vibing there. we don't touch her 🙈
  • sig — unused. also just sitting at the table not being called on 💀
  • cred — identifies the cred to use in lieu of current's. so like, whose permissions are we checking with? this one, not current's. periodt.

🔥 DESCRIPTION 🔥

Return 0 if write access is permitted.

that's it. that's the whole description. she's short and she knows it 😭 so to say it in a full sentence: if write access is permitted, you get 0 back. that's the entire contract, don't overthink it.

highkey a slay that this one gets to be so simple while the rest of the Smack family is doing the absolute most.

🌈 SEE ALSO 🌈

okay so. this is the part where the page absolutely ate — the SEE ALSO list is genuinely enormous and we are not skipping a single one, so buckle up bestie 🫶 first up, the kernel file:

  • Kernel file ./security/smack/smack_lsm.c

and now the whole squad, in order, no cap:

like... that's the whole extended friend group and every single one of them gets an invite 💖 iykyk.

okay that's the page bestie, hope this was helpful!! 🧚 this little cutie lives under ./security/smack and the version vibes are dated October 2026 — mwah, go read the rest of the Smack girls, they're all linked above ⭐👑
