🦋 smack_uring_override_creds — a lil' Kernel API Manual moment (section 9) 🦋

okay bestie, so this is smack_uring_override_creds(9), straight out of the Kernel API Manual, and it's lowkey one of those tiny gatekeeper functions that decides whether ur allowed to do a vibe change. let's get into it 💅

✨ NAME ✨

smack_uring_override_creds — literally just: is the io_uring cred override allowed? that's the whole plot 🎀

✨ SYNOPSIS ✨

int smack_uring_override_creds (const struct cred *new );

like, that's the whole signature, no cap. one argument, returns an int. iconic minimalism ✨

✨ ARGUMENTS ✨

  • new — the target creds 💖 aka the set of credentials somebody wants to slide into. this is the thing being checked, bestie.

✨ DESCRIPTION ✨

so here's the tea 🍓: this function does a check. it looks at the current task and asks, "hey, are you actually allowed to override your credentials just to service an io_uring operation?" 👀

that's it. that's the function. it's a permission gatekeeper, the bouncer at the club, the "you're not on the list" energy when you're not on the list 😭 and when you are on the list? slay, go service that io_uring operation 🧚💜

✨ SEE ALSO ✨

bestie there are SO many siblings. it's giving huge family reunion 🌈 and every single one of them is right here, in order, no skips:

💀 not me listing out an entire LSM's worth of functions. anyway. that's the family. go read them, bestie, they're all in the same file. iykyk 🫶

and that's the page, bestie!! 🌸 this one came from ./security/smack and it's dated October 2026, so like… a little time capsule from the future, periodt ✨🎀 go forth and be allowed (or not, depending on the check) 💜🦋
