aafs_create(9)

okay bestie, welcome to aafs_create(9) from the Kernel API Manual — this is the apparmorfs dentry-creation girlie and she's lowkey iconic ✨💅

🌸 NAME 🌸

aafs_create — create a dentry in the apparmorfs filesystem 🎀

✨ SYNOPSIS ✨

struct dentry * aafs_create (const char *name , umode_t mode , struct
dentry *parent , struct aa_common_ref *data , void *link , const struct
file_operations *fops , const struct inode_operations *iops );

🎀 ARGUMENTS 🎀

• name — name of the dentry to create 🏷️
• mode — permissions the file should have 🔐
• parent — parent directory for this dentry 📁
• data — data to store on inode.i_private, available in open 👀
• link — if symlink, the symlink target string 🔗
• fops — the struct file_operations that should be used for — yes, the original line literally stops there 😭
• iops — struct of inode_operations that should be used 🧠

💖 DESCRIPTION 💖

So this is the basic “create a xxx” function for apparmorfs — main character energy for making stuff in there 👑✨

If it succeeds, it returns a pointer to a dentry, and that pointer must be freed with aafs_remove 🧹. On failure, it returns ERR_PTR 💀.

bestie, don't sleep on the cleanup: success means aafs_remove later, failure means ERR_PTR. periodt 🫶
