An ioctl() would require you to have permission to open the file before you would be allowed to try to access the named attribute directory (which depends on a separate set of permissions in the NFSv4 ACL model). I don't see why we would deliberately add an implementation that is broken. If we need to add support for NFSv4 named attributes, then we should have a discussion about adding support for the O_XATTR flag. -- Trond Myklebust Linux NFS client maintainer, Hammerspace trond.myklebust@xxxxxxxxxxxxxxx
