Smbmrx queryinfo question

NTFSD
1

Hi all,
Does anyone know definitively whether file query information
requests of FILE_STANDARD_INFORMATION type should succeed over the lanman
redirector? I am filtering the mrxsmb redirector, and am getting a
STATUS_NOT_IMPLEMENTED value when I try to query for whether a “file” is a
file or a directory using the FILE_STANDARD_INFORMATION.
If this just simply doesn’t work, is there any other graceful way to
query for this information on the smb redirector?

Thanks,
Matt

2

Is this happening on ALL files you try, or just on ONE file that you
have tried. I wouldn’t be surprised to see this fail on something odd
(like a named pipe file or the volume itself) while it works on a
file/directory.

Regards,

Tony

Tony,
Yes, it is only happening some of the time. Specifically, if I try
to mount a network drive for a remote share, it happens when in my filter I
see an IRP_MJ_CREATE for the remote directory that I’m trying to map, and I
try to query for whether it is a directory or a file.

(like a named pipe file or the volume itself) while it works on a
file/directory.

This is true. On named pipes or another special MS-FS-stuff, some
queries may fail. I observed also another thing - if you use DFS,
the call may return succcess but the return information length
(in IoStatusBlock) may be set to zero.

Another case, if you query a StdInfo on named pipe from
a MS-server, it will probably work, if you try an Unix server,
it will probably fail (I observed this on Windows NT redirector).

Sorry, this query does not work on tree connect requests.

Neal,
Is it safe to assume that tree connect requests are always for a
remote directory, and not a file?

Tree connects are actually opening the “share” itself so yes, you can
assume they are never for a remote file or directory.
