fs/cifs/CHANGES

+Version 1.21
+------------
+Add new mount parm to control whether mode check (vfs_permission) is done on
+the client.  If Unix extensions are enabled and the uids on the client
+and server do not match, client permission checks are meaningless on
+server uids that do not exist on the client (this does not affect the
+normal ACL check which occurs on the server).  Fix default uid
+on mknod to match create and mkdir. Add optional mount parm to allow
+override of the default uid behavior (in which the server sets the uid
+and gid of newly created files). Normally for network filesystem mounts
+user want the server to set the uid/gid on newly created files (rather than 
+using uid of the client processes you would in a local filesystem).
+
 Version 1.20
 ------------
 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps

+  perm          Client does permission checks (vfs_permission check of uid
+		and gid of the file against the mode and desired operation),
+		Note that this is in addition to the normal ACL check on the
+		target machine done by the server software. 
+		Client permission checking is enabled by default.
+  noperm        Client does not do permission checks.  This can expose
+		files on this mount to access by other users on the local
+		client system. It is typically only needed when the server
+		supports the CIFS Unix Extensions but the UIDs/GIDs on the
+		client and server system do not match closely enough to allow
+		access by the user doing the mount.
+		Note that this does not affect the normal ACL check on the
+		target machine done by the server software (of the server
+		ACL against the user name provided at mount time).
+  setuids       If the CIFS Unix extensions are negotiated with the server
+		the client will attempt to set the effective uid and gid of
+		the local process on newly created files, directories, and
+		devices (create, mkdir, mknod).
+  nosetuids     The client will not attempt to set the uid and gid on
+		on newly created files, directories, and devices (create, 
+		mkdir, mknod) which will result in the server setting the
+		uid and gid to the default (usually the server uid of the
+		usern who mounted the share).  Letting the server (rather than
+		the client) set the uid and gid is the default. This
+		parameter has no effect if the CIFS Unix Extensions are not
+		negotiated.
