security_path_mkdir(9)

✨ security_path_mkdir(9) — Kernel API Manual ✨

okay bestie, welcome to the security_path_mkdir(9) page from the Kernel API Manual. this is the whole manual, but make it group-chat. every arg, return value, and SEE ALSO reference is staying. no cap. 🫶💖

---

💖 NAME 💖

security_path_mkdir - Check if creating a new directory is allowed

literally the permission vibe check for making a directory. 💅

🦋 SYNOPSIS 🦋

the exact signature, bestie, character for character:

int security_path_mkdir (const struct path *dir , struct dentry *dentry
, umode_t mode );

🎀 ARGUMENTS 🎀

one little bullet per argument, all deets intact: ✨

• dir — parent directory. the parent-directory arg, periodt.
• dentry — new directory. the new-directory arg, fresh out the box.
• mode — new directory mode. the mode for the new directory.

🌸 DESCRIPTION 🌸

Check permissions to create a new directory in the existing directory. So yes, it's the permission check for making a new directory inside an existing one. it's giving gatekeeping but make it kernel security. 💅

🔥 RETURN 🔥

Returns 0 if permission is granted. that's the green light, bestie. ✅
