cifs kernel module and MS DFS shares [2.6.12-1.1411_FC4]

cifs kernel module and MS DFS shares [2.6.12-1.1411_FC4]

[Thomas Chiverton]

(I was referred here by Thomas Anders over on the Samba list, as apparently 
it's the cifs kernel module at fault ?).

I am having problems mounting a DFS share using mount.cifs, even though it 
works in smbclient fine.
After mounting, each top-level directory contains a copy of the top level 
directory.
Turning up debug and verbose don't seem to help. Any ideas ?

I can mount non-DFS shares from the same CIFS server fine.

I've got the same issue but if I go down 2 or 3 levels, it works (ie
continue to go down the same directory until you see a valid content). Even
better, I can cd into non existing directories and it "works" (as in I
still see the content of the mountpoint).
So using your example, to see the real content of Consultants, I would have
to do this:
cd /mnt/dfs/Consultants/Consultants/Consultants
or this
cd /mnt/dfs/what/ev/Consultants

I haven't looked at the source yet so I'm not sure what's going on there...

Well, *something* changes after 3 levels:

 ls /mnt/dfs/Consultants/
Applications  Consultants  Engineering  Management            Version
Common        Directors    Finance      Software Development  WinTA Data

 ls /mnt/dfs/Consultants/Consultants/
Applications  Consultants  Engineering  Management            Version
Common        Directors    Finance      Software Development  WinTA Data

 ls /mnt/dfs/Consultants/Consultants/Consultants/
ls: reading directory /mnt/dfs/Consultants/Consultants/Consultants/: Object is 
remote

Anyone else ?
Should I be logging a bug at redhat instead of posting here ?
