💅 smack_file_alloc_security — Kernel API Manual ✨

okay so bestie, we're in the Kernel API Manual, section 9, and today's main character is smack_file_alloc_security. it's a little one but she's iconic in her own low-key way 🎀

🌸 NAME 🌸

smack_file_alloc_security — assign a file security blob 🦋

✨ SYNOPSIS ✨

int smack_file_alloc_security (struct file *file );

🧚 ARGUMENTS 🧚

  • file — the object 💖 (that's it. that's the whole argument. she's low maintenance.)

👑 DESCRIPTION 👑

so here's the tea, bestie: the security blob for a file is literally just a pointer to the master label list. that means no allocation is done — none, zero, nada. the function is out here doing the absolute least and honestly? we respect it. no cap 💀

f_security is the owner security information. and before you get any ideas — it isn't used on file access checks. that is not her job. she's for send_sigio. periodt. 🫶

Returns 0 — that's it, that's the whole return value, a big fat zero and a slay ✨
