FILE_STREAM_INFORMATION responses are assembled without aligning entries and truncated to the client buffer length after the fact. A short query can therefore return STATUS_BUFFER_OVERFLOW with an incomplete entry and a nonzero NextEntryOffset, which clients may reject as an invalid network response. Standalone queries can also exhaust the server response buffer and silently omit streams while reporting success. Allocate the same large response buffer used by other variable-length QUERY_INFO classes for stream queries. Pack only complete entries within the requested output length and available response space, aligning each entry to eight bytes and sizing names after UTF-16 conversion. Return STATUS_BUFFER_OVERFLOW when more entries remain, using an SMB2 error response if no entry fits.
