40 * This is the new flexible, extensible style NFSv2/v3 file handle.
41 * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
42 *
43 * The file handle starts with a sequence of four-byte words.
44 * The first word contains a version number (1) and three descriptor bytes
45 * that tell how the remaining 3 variable length fields should be handled.
46 * These three bytes are auth_type, fsid_type and fileid_type.
47 *
48 * All four-byte values are in host-byte-order.
49 *
50 * The auth_type field specifies how the filehandle can be authenticated
51 * This might allow a file to be confirmed to be in a writable part of a
52 * filetree without checking the path from it up to the root.
53 * Current values:
54 * 0 - No authentication. fb_auth is 0 bytes long
55 * Possible future values:
56 * 1 - 4 bytes taken from MD5 hash of the remainer of the file handle
57 * prefixed by a secret and with the important export flags.
58 *
59 * The fsid_type identifies how the filesystem (or export point) is
60 * encoded.
61 * Current values:
62 * 0 - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
63 * NOTE: we cannot use the kdev_t device id value, because kdev_t.h
64 * says we mustn't. We must break it up and reassemble.
65 * 1 - 4 byte user specified identifier
66 * 2 - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
67 * 3 - 4 byte device id, encoded for user-space, 4 byte inode number
68 * 4 - 4 byte inode number and 4 byte uuid
69 * 5 - 8 byte uuid
70 * 6 - 16 byte uuid
71 * 7 - 8 byte inode number and 16 byte uuid
72 *
73 * The fileid_type identified how the file within the filesystem is encoded.
74 * This is (will be) passed to, and set by, the underlying filesystem if it supports
75 * filehandle operations. The filesystem must not use the value '0' or '0xff' and may
76 * only use the values 1 and 2 as defined below:
77 * Current values:
78 * 0 - The root, or export point, of the filesystem. fb_fileid is 0 bytes.
79 * 1 - 32bit inode number, 32 bit generation number.
80 * 2 - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.
