commit 758d61201f7b51da6ce74aee2d18c5125d72522e
Author: Stefan Metzmacher <metze at samba.org>
Date: Wed May 23 13:09:40 2012 +0200
s3:smbd/msdfs: pass 'allow_broken_path' to get_referred_path()
Note the DCERPC code should not be smb2 specific!
I wonder why this is at all smb2 specific...

commit 0733183594dbd3ce07ddaf9e1fcf8102b80fc605
Author: Stefan Metzmacher <metze at samba.org>
Date: Thu May 24 10:43:56 2012 +0200
s3:smbd/files: work without sconn->file_bmap and assign fsp->fnum = -1
For faked connection_structs we do not need valid fnum values,
e.g. in the dfs and printing code.
