A Partial List of Missing Features
==================================
for visible, important contributions to this module. Here
is a partial list of the known problems and missing features:
-a) Support for SecurityDescriptors for chmod/chgrp/chown so
-these can be supported for Windows servers
+a) Support for SecurityDescriptors(Windows/CIFS ACLs) for chmod/chgrp/chown
+so that these operations can be supported to Windows servers
-b) Better pam/winbind integration (e.g. to handle uid mapping
-better)
+b) Mapping POSIX ACLs (and eventually NFSv4 ACLs) to CIFS
+SecurityDescriptors
-c) multi-user mounts - multiplexed sessionsetups over single vc
-(ie tcp session) - more testing needed
+c) Better pam/winbind integration (e.g. to handle uid mapping
+better)
d) Kerberos/SPNEGO session setup support - (started)
-e) NTLMv2 authentication (mostly implemented)
+e) NTLMv2 authentication (mostly implemented - double check
+that NTLMv2 signing works, also need to cleanup now unneeded SessSetup code in
+fs/cifs/connect.c)
f) MD5-HMAC signing SMB PDUs when SPNEGO style SessionSetup
used (Kerberos or NTLMSSP). Signing alreadyimplemented for NTLM
using FindNotify or equivalent. - (started)
g) A few byte range testcases fail due to POSIX vs. Windows/CIFS
-style byte range lock differences
+style byte range lock differences. Save byte range locks so
+reconnect can replay them.
+
+h) Support unlock all (unlock 0,MAX_OFFSET)
+by unlocking all known byte range locks that we locked on the file.
-h) quota support
+i) quota support (needs minor kernel change since quota calls
+to make it to network filesystems or deviceless filesystems)
-j) finish writepages support (multi-page write behind for improved
-performance) and syncpage
+j) investigate sync behavior (including syncpage) and check
+for proper behavior of intr/nointr
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.
at a time when 8 pages or more are requested. In conjuntion
add support for async_cifs_readpages.
-p) Add support for storing symlink and fifo info to Windows servers
+p) Add support for storing symlink info to Windows servers
in the Extended Attribute format their SFU clients would recognize.
q) Finish fcntl D_NOTIFY support so kde and gnome file list windows
-will autorefresh (started)
+will autorefresh (partially complete by Asser). Needs minor kernel
+vfs change to support removing D_NOTIFY on a file.
r) Add GUI tool to configure /proc/fs/cifs settings and for display of
the CIFS statistics (started)
-q) implement support for security and trusted categories of xattrs
+s) implement support for security and trusted categories of xattrs
(requires minor protocol extension) to enable better support for SELINUX
-r) Implement O_DIRECT flag on open (already supported on mount)
+t) Implement O_DIRECT flag on open (already supported on mount)
-s) Allow remapping of last remaining character (\) to +0xF000 which
-(this character is valid for POSIX but not for Windows)
-
-t) Create UID mapping facility so server UIDs can be mapped on a per
+u) 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
standard for asking the server for the corresponding name of a
particular uid.
-KNOWN BUGS (updated April 29, 2005)
+v) Add support for CIFS Unix and also the newer POSIX extensions to the
+server side for Samba 4.
+
+w) Finish up the dos time conversion routines needed to return old server
+time to the client (default time, of now or time 0 is used now for these
+very old servers)
+
+x) 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)
+
+y) Finish testing of Windows 9x/Windows ME server support (started).

+KNOWN BUGS (updated February 26, 2007)
====================================
See http://bugzilla.samba.org - search on product "CifsVFS" for
current bug list.
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) 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

-than to Windows.
Misc testing to do
==================
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.
+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,
4) More exhaustively test against less common servers. More testing
against Windows 9x, Windows ME servers.

+DOS attrs - returned as pseudo-xattr in Samba format (check VFAT and NTFS for this too)
+
+mount check for unmatched uids - and uid override
+
+Add mount option for Linux extension disable per mount, and partial disable per mount (uid off, symlink/fifo/mknod on but what about posix acls?)
