* This is the new flexible, extensible style NFSv2/v3 file handle.
|

* by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
|
||||
*
|
||||
* The file handle starts with a sequence of four-byte words.
|
||||
* The first word contains a version number (1) and three descriptor bytes
|
||||
* that tell how the remaining 3 variable length fields should be handled.
|
||||
* These three bytes are auth_type, fsid_type and fileid_type.
|
||||
*
|
||||
* All four-byte values are in host-byte-order.
|
||||
*
|
||||
* The auth_type field specifies how the filehandle can be authenticated
|
||||
* This might allow a file to be confirmed to be in a writable part of a
|
||||
* filetree without checking the path from it up to the root.
|
||||
* Current values:
|
||||
* 0 - No authentication. fb_auth is 0 bytes long
|
||||
* Possible future values:
|
||||
* 1 - 4 bytes taken from MD5 hash of the remainer of the file handle
|
||||
* prefixed by a secret and with the important export flags.
|
||||
*
|
||||
* The fsid_type identifies how the filesystem (or export point) is
|
||||
* encoded.
|
||||
* Current values:
|
||||
* 0 - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
|
||||
* NOTE: we cannot use the kdev_t device id value, because kdev_t.h
|
||||
* says we mustn't. We must break it up and reassemble.
|
||||
* 1 - 4 byte user specified identifier
|
||||
* 2 - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
|
||||
* 3 - 4 byte device id, encoded for user-space, 4 byte inode number
|
||||
* 4 - 4 byte inode number and 4 byte uuid
|
||||
* 5 - 8 byte uuid
|
||||
* 6 - 16 byte uuid
|
||||
* 7 - 8 byte inode number and 16 byte uuid
|
||||
*
|
||||
* The fileid_type identified how the file within the filesystem is encoded.
|
||||
* This is (will be) passed to, and set by, the underlying filesystem if it supports
|
||||
* filehandle operations. The filesystem must not use the value '0' or '0xff' and may
|
||||
* only use the values 1 and 2 as defined below:
|
||||
* Current values:
|
||||
* 0 - The root, or export point, of the filesystem. fb_fileid is 0 bytes.
|
||||
* 1 - 32bit inode number, 32 bit generation number.
|
||||
* 2 - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.
