ksmbd: support normalized name information

Browse source

FILE_NORMALIZED_NAME_INFORMATION is not handled and is returned as
STATUS_INVALID_INFO_CLASS. SMB 3.1.1 clients use this information class
to obtain the share-relative path with the on-disk name casing.

Build the normalized path from the opened dentry, remove the leading
share-relative separator, and recover the canonical named-stream casing
from its backing xattr. Return an empty name for the share root and
STATUS_NOT_SUPPORTED for dialects older than SMB 3.1.1.

Also distinguish a named $DATA stream on a directory from the unnamed
data stream so that directory:stream:$DATA can be opened normally.

This fixes smb2.getinfo.normalized.
