smk_read_cipso_auto_level(9)

💅 smk_read_cipso_auto_level — the kernel API manual, bestie edition 🎀

okay so this is smk_read_cipso_auto_level(9) from the kernel API manual, and it's literally the read() side of things for smackfs/direct and smackfs/mapped. yes. that's the whole vibe. let's get into it 🦋

---

✨ SYNOPSIS ✨

ssize_t smk_read_cipso_auto_level (struct file *filp , char __user *buf
, size_t count , loff_t *ppos );

like, the whole signature. every character. don't @ me 💅

---

🌸 ARGUMENTS 🌸

• filp — the file pointer, bestie. it's giving "which file are we even talking about" energy.
• buf — where to put the result 👑 this is the destination, the moment, the main character.
• count — the maximum to send along. so like, a hard cap. don't overdo it 🫶
• ppos — where to start. your starting point. your origin story ✨

---

💖 DESCRIPTION 💖

Returns number of bytes read or error code, as appropriate. that's it. that's the whole description. no cap 🧚

so lowkey: it hands you back a byte count when things go right, and an error code when they don't. "as appropriate" — the kernel is being mysterious and honestly? iconic 💀

this page came from the ./security/smack corner of the kernel, dated October 2026, and it's part of the Kernel API Manual (the 9 section, iykyk). go read the other 50-something pages, bestie — they're all waiting 🌈⭐🍓
