+Original Author
+===============
+Steve French (sfrench@samba.org)
+
+The author wishes to express his appreciation and thanks to:
+Andrew Tridgell (Samba team) for his early suggestions about smb/cifs VFS
+improvements. Thanks to IBM for allowing me time and test resources to pursue
+this project, to Jim McDonough from IBM (and the Samba Team) for his help, to
+the IBM Linux JFS team for explaining many esoteric Linux filesystem features.
+Jeremy Allison of the Samba team has done invaluable work in adding the server
+side of the original CIFS Unix extensions and reviewing and implementing
+portions of the newer CIFS POSIX extensions into the Samba 3 file server. Thank
+Dave Boutcher of IBM Rochester (author of the OS/400 smb/cifs filesystem client)
+for proving years ago that very good smb/cifs clients could be done on Unix-like
+operating systems.  Volker Lendecke, Andrew Tridgell, Urban Widmark, John 
+Newbigin and others for their work on the Linux smbfs module.  Thanks to
+the other members of the Storage Network Industry Association CIFS Technical
+Workgroup for their work specifying this highly complex protocol and finally
+thanks to the Samba team for their technical advice and encouragement.

+
+A Partial List of Missing Features
+==================================
+
+Contributions are welcome.  There are plenty of opportunities
+for visible, important contributions to this module.  Here
+is a partial list of the known problems and missing features:
+
+a) Support for SecurityDescriptors(Windows/CIFS ACLs) for chmod/chgrp/chown
+so that these operations can be supported to Windows servers
+
+b) Mapping POSIX ACLs (and eventually NFSv4 ACLs) to CIFS
+SecurityDescriptors
+
+c) Better pam/winbind integration (e.g. to handle uid mapping
+better)
+
+d) Kerberos/SPNEGO session setup support - (started)
+
+e) Cleanup now unneeded SessSetup code in
+fs/cifs/connect.c and add back in NTLMSSP code if any servers
+need it
+
+f) MD5-HMAC signing SMB PDUs when SPNEGO style SessionSetup 
+used (Kerberos or NTLMSSP). Signing alreadyimplemented for NTLM
+and raw NTLMSSP already. This is important when enabling
+extended security and mounting to Windows 2003 Servers
+
+g) Directory entry caching relies on a 1 second timer, rather than 
+using FindNotify or equivalent.  - (started)
+
+h) quota support (needs minor kernel change since quota calls
+to make it to network filesystems or deviceless filesystems)
+
+i) investigate sync behavior (including syncpage) and check  
+for proper behavior of intr/nointr
+
+j) hook lower into the sockets api (as NFS/SunRPC does) to avoid the
+extra copy in/out of the socket buffers in some cases.
+
+k) Better optimize open (and pathbased setfilesize) to reduce the
+oplock breaks coming from windows srv.  Piggyback identical file
+opens on top of each other by incrementing reference count rather
+than resending (helps reduce server resource utilization and avoid
+spurious oplock breaks).
+
+l) Improve performance of readpages by sending more than one read
+at a time when 8 pages or more are requested. In conjuntion
+add support for async_cifs_readpages.
+
+m) Add support for storing symlink info to Windows servers 
+in the Extended Attribute format their SFU clients would recognize.
+
+n) Finish fcntl D_NOTIFY support so kde and gnome file list windows
+will autorefresh (partially complete by Asser). Needs minor kernel
+vfs change to support removing D_NOTIFY on a file.   
+
+o) Add GUI tool to configure /proc/fs/cifs settings and for display of
+the CIFS statistics (started)
+
+p) implement support for security and trusted categories of xattrs
+(requires minor protocol extension) to enable better support for SELINUX
+
+q) Implement O_DIRECT flag on open (already supported on mount)
+
+r) Create UID mapping facility so server UIDs can be mapped on a per
+mount or a per server basis to client UIDs or nobody if no mapping
+exists.  This is helpful when Unix extensions are negotiated to
+allow better permission checking when UIDs differ on the server
+and client.  Add new protocol request to the CIFS protocol 
+standard for asking the server for the corresponding name of a
+particular uid.
+
+s) Add support for CIFS Unix and also the newer POSIX extensions to the
+server side for Samba 4.
+
+t) In support for OS/2 (LANMAN 1.2 and LANMAN2.1 based SMB servers) 
+need to add ability to set time to server (utimes command)
+
+u) DOS attrs - returned as pseudo-xattr in Samba format (check VFAT and NTFS for this too)
+
+v) mount check for unmatched uids
+
+w) Add support for new vfs entry points for setlease and fallocate 
+
+x) Fix Samba 3 server to handle Linux kernel aio so dbench with lots of 
+processes can proceed better in parallel (on the server)
+
+y) Fix Samba 3 to handle reads/writes over 127K (and remove the cifs mount
+restriction of wsize max being 127K) 
+
+KNOWN BUGS (updated April 24, 2007)
+====================================
+See http://bugzilla.samba.org - search on product "CifsVFS" for
+current bug list.
+
+1) existing symbolic links (Windows reparse points) are recognized but
+can not be created remotely. They are implemented for Samba and those that
+support the CIFS Unix extensions, although earlier versions of Samba
+overly restrict the pathnames.
+2) follow_link and readdir code does not follow dfs junctions
+but recognizes them
+3) create of new files to FAT partitions on Windows servers can
+succeed but still return access denied (appears to be Windows 
+server not cifs client problem) and has not been reproduced recently.
+NTFS partitions do not have this problem.
+4) Unix/POSIX capabilities are reset after reconnection, and affect
+a few fields in the tree connection but we do do not know which
+superblocks to apply these changes to.  We should probably walk
+the list of superblocks to set these.  Also need to check the
+flags on the second mount to the same share, and see if we
+can do the same trick that NFS does to remount duplicate shares.
+
+Misc testing to do
+==================
+1) check out max path names and max path name components against various server
+types. Try nested symlinks (8 deep). Return max path name in stat -f information
+
+2) Modify file portion of ltp so it can run against a mounted network
+share and run it against cifs vfs in automated fashion.
+
+3) Additional performance testing and optimization using iozone and similar - 
+there are some easy changes that can be done to parallelize sequential writes,
+and when signing is disabled to request larger read sizes (larger than 
+negotiated size) and send larger write sizes to modern servers.
+
+4) More exhaustively test against less common servers.  More testing
+against Windows 9x, Windows ME servers.
