entry_create_file(9)

💅 entry_create_file(9) — like, the apparmor securityfs file-entry maker ✨

okay bestie, so we're in the Kernel API Manual today (very demure, very kernel) and this page is all about entry_create_file — the little function that creates a file entry in the apparmor securityfs. yes. that's the whole vibe. let's get into it 🎀

---

✨ SYNOPSIS ✨

int entry_create_file (struct aa_sfs_entry *fs_file , struct dentry
*parent );

like, she takes two things and gives you back an int. simple. iconic. no notes 💅

---

🫶 ARGUMENTS 🫶

• fs_file — the aa_sfs_entry you're building an entry for. and no, she cannot be NULL — that's a hard NOT NULL, bestie, do not test her 🙈
• parent — the parent dentry in the securityfs. like, where this file entry is gonna live. her mom, basically 👑

---

🌸 DESCRIPTION 🌸

so you make the entry with this fn, right? and when you're done with it, you use entry_remove_file to remove entries created with this fn. that's it. that's the tea ☕ pairing them up is the whole point — create with one, clean up with the other, no cap ✨

fr fr, don't just leave your entries lying around — entry_remove_file is right there and she's waiting 🫶
