🎀 NAME 🎀

bpf_remove_dentry_xattr — remove a xattr of a dentry 🫶

✨ SYNOPSIS ✨

__bpf_kfunc int bpf_remove_dentry_xattr (struct dentry *dentry , const
       char *name__str );

🌸 ARGUMENTS 🌸

• dentry — dentry to get xattr from. That’s the dentry target, bestie 🌟
• name__str — name of the xattr. It’s literally the string name you’re working with 🏷️

🦋 DESCRIPTION 🦋

Remove xattr name__str of dentry. Periodt 💅

Security check time 🚨: for security reasons, only name__str with prefix "security.bpf." is allowed.

Also, important context: the caller has not locked dentry->d_inode. That’s the situation, no cap 🫶.
