-version 1.36 September 6, 2005
+Version 1.53 May 20, 2008
A Partial List of Missing Features
==================================
c) Better pam/winbind integration (e.g. to handle uid mapping
better)
-d) Kerberos/SPNEGO session setup support - (started)
+d) Cleanup now unneeded SessSetup code in
+fs/cifs/connect.c and add back in NTLMSSP code if any servers
+need it
-e) NTLMv2 authentication (mostly implemented)
-
-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
+e) fix NTLMv2 signing when two mounts with different users to same
+server.
f) Directory entry caching relies on a 1 second timer, rather than
using FindNotify or equivalent. - (started)
-g) A few byte range testcases fail due to POSIX vs. Windows/CIFS
-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.
-
-i) quota support (needs minor kernel change since quota calls
+g) 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. Started by Shaggy.
+h) 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.
+i) improve support for very old servers (OS/2 and Win9x for example)
+Including support for changing the time remotely (utimes command).
-l) finish support for IPv6. This is mostly complete but
-needs a simple conversion of ipv6 to sin6_addr from the
-address in string representation.
+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.
-m) Better optimize open (and pathbased setfilesize) to reduce the
+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).
-o) Improve performance of readpages by sending more than one read
+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.
-p) Add support for storing symlink and fifo info to Windows servers
+m) 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
+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.
-r) Add GUI tool to configure /proc/fs/cifs settings and for display of
+o) Add GUI tool to configure /proc/fs/cifs settings and for display of
the CIFS statistics (started)
-s) implement support for security and trusted categories of xattrs
+p) implement support for security and trusted categories of xattrs
(requires minor protocol extension) to enable better support for SELINUX
-t) Implement O_DIRECT flag on open (already supported on mount)
+q) Implement O_DIRECT flag on open (already supported on mount)
-u) Create UID mapping facility so server UIDs can be mapped on a per
+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
standard for asking the server for the corresponding name of a
particular uid.
-v) Add support for CIFS Unix and also the newer POSIX extensions to the
+s) 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)
+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)
-x) Add support for OS/2 (LANMAN 1.2 and LANMAN2.1 based SMB servers)
+u) DOS attrs - returned as pseudo-xattr in Samba format (check VFAT and NTFS for this too)
-y) Finish testing of Windows 9x/Windows ME server support (started).
+v) mount check for unmatched uids
-KNOWN BUGS (updated April 29, 2005)
+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)
+

====================================
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
-see why lock test case 7 takes longer to complete to Samba
-than to Windows.
+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
==================
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.
