📦 version 7.3.1, in nixpkgs unstable

💅 security_uring_cmd 💅

okay so bestie, we're in the Kernel API Manual section of the man pages (man 9 territory, the deep lore) and today's main character is security_uring_cmd. ngl this one is short but she is important ✨

🌸 NAME 🌸

security_uring_cmd — the little security hook that checks whether an io_uring passthrough command is even allowed to happen 🔥

✨ SYNOPSIS ✨

int security_uring_cmd (struct io_uring_cmd *ioucmd );

like yes that's the whole signature, she's petite 💅

🎀 ARGUMENTS 🎀

  • ioucmd — the command. literally the io_uring_cmd struct in question, that's the whole vibe 🦋

💖 DESCRIPTION 💖

okay so what she does: she checks whether the file_operations uring_cmd is allowed to run. that's it, that's the job. a whole little vibe check for your passthrough command before it gets to strut around 🫶

no cap, this is the gatekeeper. if the LSM says no, the command does not get to have main character energy. periodt.

🌈 RETURN 🌈

Returns 0 if permission is granted 💚 (zero means we slay, we're good, we may proceed ✨)
