+A Partial List of Missing Features
+==================================
Contributions are welcome. There are plenty of opportunities
for visible, important contributions to this module. Here
a) Support for SecurityDescriptors for chmod/chgrp/chown so
these can be supported for Windows servers
-b) Better pam/winbind integration
+b) Better pam/winbind integration (e.g. to handle uid mapping
+better)
c) multi-user mounts - multiplexed sessionsetups over single vc
(ie tcp session) - prettying up needed
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

f) Directory entry caching relies on a 1 second timer, rather than
using FindNotify or equivalent. - (started)
h) quota support
-i) support for the Linux 2.5 kernel new feature get_xattr and set_xattr
-which will allow us to expose dos attributes as well as real
-ACLs
-
-k) finish writepages support (multi-page write behind for improved

performance) and syncpage

+k) hook lower into the sockets api (as NFS/SunRPC does) to avoid the
extra copy in/out of the socket buffers in some cases.
-m) finish support for IPv6
+l) finish support for IPv6. This is mostly complete but
+needs a simple inet_pton like function to convert ipv6
+addresses in string representation.
-o) Better optimize open (and pathbased setfilesize) to reduce the
+m) 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).
-p) Improve performance of readpages by sending more than one read
-at a time when 8 pages or more are requested.
+o) Improve performance of readpages by sending more than one read
+at a time when 8 pages or more are requested. Evaluate whether
+reads larger than 16K would be helpful.
+
+p) For support of Windows9x/98 we need to retry failed mounts
+to *SMBSERVER (default server name) with the uppercase hostname
+in the RFC1001 session_init request.
+
+q) Add support for storing symlink and fifo info to Windows servers
+in the Extended Attribute format their SFU clients would recognize.
+
+r) Finish fcntl D_NOTIFY support so kde and gnome file list windows
+will autorefresh
+s) Add GUI tool to configure /proc/fs/cifs settings and for display of
+the CIFS statistics
-KNOWN BUGS (updated January 30, 2004)
+KNOWN BUGS (updated May 27, 2004)
====================================
1) existing symbolic links (Windows reparse points) are recognized but
can not be created remotely. They are implemented for Samba and those that
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
-not client problem). NTFS partitions do not have this problem.
-4) debug connectathon special test case nfs_idem (which does
-some invalid symlink naming, or at least what Samba thinks
-is an invalid symlink target).
-5) debug connectation lock test case 10 which fails against
+server not cifs client problem) and has not been reproduced recently.
+NTFS partitions do not have this problem.
+4) debug connectathon lock test case 10 which fails against
Samba (may be unmappable due to POSIX to Windows lock model
differences but worth investigating). Also debug Samba to
see why lock test case 7 takes longer to complete to Samba
than to Windows.
+5) implement search rewind (seeking backward in a readdir), which is
+necessary for one of the "special" subsection of posix file API
+tests in the Connectathon nfs test suite.
Misc testing to do
-=================
+==================
1) check out max path names and max path name components against various server
-types.
+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.
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 the recently added NT4 support
+4) More exhaustively test the recently added NT4 support against various
+NT4 service pack levels, and fix cifs_setattr for setting file times and
+size to fall back to level 1 when error invalid level returned.
