Merge in fixes from version 0.6.5 of the CIFS VFS.  Greatly improved performance including improved distributed caching support and support for readpages and larger read sizes. Cache data now flushed properly at file close time. Socket and memory leak fixed.  Fix two oops. Fix error logging and made more consistent.  Generic sendfile added.

View file @ b668ec86
Version 0.65
------------
Finish fixes to commit write for caching/readahead consistency. fsx
now works to Samba servers. Fix oops caused when readahead
was interrupted by a signal.
Version 0.64
------------
Fix data corruption (in partial page after truncate) that caused fsx to
fail to Windows servers. Cleaned up some extraneous error logging in
common error paths. Add generic sendfile support.
Version 0.63
------------
Fix memory leak in AllocMidQEntry.
Finish reconnection logic, so connection with server can be dropped
(or server rebooted) and the cifs client will reconnect.
Version 0.62
------------
Fix temporary socket leak when bad userid or password specified
(or other SMBSessSetup failure). Increase maximum buffer size to slightly
over 16K to allow negotiation of up to Samba and Windows server default read
sizes. Add support for readpages
Version 0.61
------------
Fix oops when username not passed in on mount. Extensive fixes and improvements
to error logging (strip redundant newlines, change debug macros to ensure newline
passed in and to be more consistent). Fix writepage wrong file handle problem,
a readonly file handle could be incorrectly used to attempt to write out
file updates through the page cache to multiply open files. This could cause
the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
shares to the same Windows server when using different usernames
(doing this to Samba servers worked but Windows was rejecting it) - now it is
possible to use different userids when connecting to the same server from a
Linux client. Fix oops when treeDisconnect called during unmount on
previously freed socket.
Version 0.60
------------
Fix oops in readpages caused by not setting address space operations in inode in

A Partial List of Known Problems and Missing Features

is a partial list of the known problems and missing features:
a) Support for SecurityDescriptors for chmod/chgrp/chown

these can be supported for Windows servers
b) Better pam/winbind integration

f) oplock support (ie safe CIFS distributed file caching) is not quite complete.
In addition Directory entry caching relies on a 1 second timer, rather than
using FindNotify or equivalent. - (started)
......@@ -28,27 +29,34 @@ of recent 2.5 kernel improvements in byte-range locking
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
j) finish off the mount helper, mount.cifs - (started)
KNOWN BUGS (updated October 8nd, 2002)
k) finish writepages support (multi-page write behind for improved
performance) and syncpage
l) 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
KNOWN BUGS (updated February 15, 2003)
====================================
1) symbolic links (Windows reparse points) are recognized but
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 but Samba has a bug currently handling
symlink text beginning with slash
2) delete of file with read-only attribute set will fail (may be ok)
3) autoreconnection logic is only partially complete.
4) there may be a problem with truncating a memmapped file to smaller than 4k with
the size being reported as exactly 4k.
Misc testing to do
=================
1) check out max path names and max path name components against various server
types.
2) Run POSIX bencharks against cifs
2) Run dbench
3) Run dbench
3) Finish FSX testing on SMP now that we workaround the Samba bug
4) Finish FSX testing on SMP now that we workaround the Samba bug
