security_inode_remove_acl(9)

💅 security_inode_remove_acl(9)

okay so this is straight out of the Kernel API Manual, and the main character is security_inode_remove_acl. It's giving "security hook for removing a posix acl," and honestly? iconic. Let's get into it, bestie. ✨

---

🌸 NAME

security_inode_remove_acl — check if removing a posix acl is allowed.

---

✨ SYNOPSIS

       int security_inode_remove_acl (struct mnt_idmap *idmap , struct dentry
       *dentry , const char *acl_name );

---

🎀 ARGUMENTS

• idmap — idmap of the mount. That's the mount's idmap vibe, periodt.
• dentry — file. Yes, literally the file in question.
• acl_name — acl name. This is the lil name tag that tells you which acl we're talking about.

---

💖 DESCRIPTION

Check permission before removing posix acls, bestie. The posix acls are identified by acl_name — so acl_name is literally how we know which one is getting removed. Slay. 🦋

---

🔥 RETURN

Returns 0 if permission is granted. That 0 is the green-light bestie moment. 💚
