This patch fixes typos in various Documentation txts. The patch addresses some +words starting with the letters 'U-Z'. Looks like I made it through the alphabet...just in time to start over again +too! Maybe I can fit more profound fixes into the next round...? Time will +tell. :) Signed-off-by: Matt LaPlante <kernel1@cyberdogtech.com> Acked-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Adrian Bunk <bunk@stusta.de>

Mount options for ADFS
|
|
----------------------
|
|
|
|
uid=nnn All files in the partition will be owned by
|
|
user id nnn. Default 0 (root).
|
|
gid=nnn All files in the partition will be in group
|
|
nnn. Default 0 (root).
|
|
ownmask=nnn The permission mask for ADFS 'owner' permissions
|
|
will be nnn. Default 0700.
|
|
othmask=nnn The permission mask for ADFS 'other' permissions
|
|
will be nnn. Default 0077.
|
|
|
|
Mapping of ADFS permissions to Linux permissions
|
|
------------------------------------------------
|
|
|
|
ADFS permissions consist of the following:
|
|
|
|
Owner read
|
|
Owner write
|
|
Other read
|
|
Other write
|
|
|
|
(In older versions, an 'execute' permission did exist, but this
|
|
does not hold the same meaning as the Linux 'execute' permission
|
|
and is now obsolete).
|
|
|
|
The mapping is performed as follows:
|
|
|
|
Owner read -> -r--r--r--
|
|
Owner write -> --w--w---w
|
|
Owner read and filetype UnixExec -> ---x--x--x
|
|
These are then masked by ownmask, eg 700 -> -rwx------
|
|
Possible owner mode permissions -> -rwx------
|
|
|
|
Other read -> -r--r--r--
|
|
Other write -> --w--w--w-
|
|
Other read and filetype UnixExec -> ---x--x--x
|
|
These are then masked by othmask, eg 077 -> ----rwxrwx
|
|
Possible other mode permissions -> ----rwxrwx
|
|
|
|
Hence, with the default masks, if a file is owner read/write, and
|
|
not a UnixExec filetype, then the permissions will be:
|
|
|
|
-rw-------
|
|
|
|
However, if the masks were ownmask=0770,othmask=0007, then this would
|
|
be modified to:
|
|
-rw-rw----
|
|
|
|
There is no restriction on what you can do with these masks. You may
|
|
wish that either read bits give read access to the file for all, but
|
|
keep the default write protection (ownmask=0755,othmask=0577):
|
|
|
|
-rw-r--r--
|
|
|
|
You can therefore tailor the permission translation to whatever you
|
|
desire the permissions should be under Linux.
