Re: Getting CIFS ACLs larger than CIFSMaxBufSize

The linux cifs client doesn't seem to handle NT_STATUS_BUFFER_TOO_SMALL,
it just sends the initial negotiated buffer size as max data count for
trans2. So, if the server
has more data than the client requested, it would fail. Why is this not
handled
in linux cifs client?
