+
+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) SMB3 (and SMB3.02) missing optional features:
+ - RDMA (started)
+ - multichannel (started)
+ - directory leases (improved metadata caching)
+ - T10 copy offload (copy chunk is only mechanism supported)
+
+b) improved sparse file support
+
+c) Directory entry caching relies on a 1 second timer, rather than
+using Directory Leases
+
+d) quota support (needs minor kernel change since quota calls
+to make it to network filesystems or deviceless filesystems)
+
+e) Better optimize open to reduce redundant opens (using reference
+counts more) and to improve use of compounding in SMB3 to reduce
+number of roundtrips.
+
+f) Finish inotify 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.
+
+g) Add GUI tool to configure /proc/fs/cifs settings and for display of
+the CIFS statistics (started)
+
+h) implement support for security and trusted categories of xattrs
+(requires minor protocol extension) to enable better support for SELINUX
+
+i) Implement O_DIRECT flag on open (already supported on mount)
+
+j) 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. Also better integration with winbind for resolving SID owners
+
+k) Add tools to take advantage of more smb3 specific ioctls and features
+
+l) encrypted file support
+
+m) improved stats gathering, tools (perhaps integration with nfsometer?)
+
+n) allow setting more NTFS/SMB3 file attributes remotely (currently limited to compressed
+file attribute via chflags) and improve user space tools for managing and
+viewing them.
+
+o) mount helper GUI (to simplify the various configuration options on mount)
+
+p) autonegotiation of dialects (offering more than one dialect ie SMB3.02,
+SMB3, SMB2.1 not just SMB3).
+
+q) Allow mount.cifs to be more verbose in reporting errors with dialect
+or unsupported feature errors.
+
+r) updating cifs documentation, and user guid.
+
+s) Addressing bugs found by running a broader set of xfstests in standard
+file system xfstest suite.
+
+t) split cifs and smb3 support into separate modules so legacy (and less
+secure) CIFS dialect can be disabled in environments that don't need it
+and simplify the code.
+
+u) Finish up SMB3.1.1 dialect support
+
+v) POSIX Extensions for SMB3.1.1
+
+KNOWN BUGS
+====================================
+See http://bugzilla.samba.org - search on product "CifsVFS" for
+current bug list. Also check http://bugzilla.kernel.org (Product = File System, Component = CIFS)
+
+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
+
+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) Improve xfstest's cifs enablement and adapt xfstests where needed to test
+cifs better
+
+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
