43 | * This is the new flexible, extensible style NFSv2/v3 file handle. | ||
44 | * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000 | ||
45 | * | ||
46 | * The file handle starts with a sequence of four-byte words. | ||
47 | * The first word contains a version number (1) and three descriptor bytes | ||
48 | * that tell how the remaining 3 variable length fields should be handled. | ||
49 | * These three bytes are auth_type, fsid_type and fileid_type. | ||
50 | * | ||
51 | * All four-byte values are in host-byte-order. | ||
52 | * | ||
53 | * The auth_type field specifies how the filehandle can be authenticated | ||
54 | * This might allow a file to be confirmed to be in a writable part of a | ||
55 | * filetree without checking the path from it up to the root. | ||
56 | * Current values: | ||
57 | * 0 - No authentication. fb_auth is 0 bytes long | ||
58 | * Possible future values: | ||
59 | * 1 - 4 bytes taken from MD5 hash of the remainer of the file handle | ||
60 | * prefixed by a secret and with the important export flags. | ||
61 | * | ||
62 | * The fsid_type identifies how the filesystem (or export point) is | ||
63 | * encoded. | ||
64 | * Current values: | ||
65 | * 0 - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number | ||
66 | * NOTE: we cannot use the kdev_t device id value, because kdev_t.h | ||
67 | * says we mustn't. We must break it up and reassemble. | ||
68 | * 1 - 4 byte user specified identifier | ||
69 | * 2 - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED | ||
70 | * 3 - 4 byte device id, encoded for user-space, 4 byte inode number | ||
71 | * 4 - 4 byte inode number and 4 byte uuid | ||
72 | * 5 - 8 byte uuid | ||
73 | * 6 - 16 byte uuid | ||
74 | * 7 - 8 byte inode number and 16 byte uuid | ||
75 | * | ||
76 | * The fileid_type identified how the file within the filesystem is encoded. | ||
77 | * This is (will be) passed to, and set by, the underlying filesystem if it supports | ||
78 | * filehandle operations. The filesystem must not use the value '0' or '0xff' and may | ||
79 | * only use the values 1 and 2 as defined below: | ||
80 | * Current values: | ||
81 | * 0 - The root, or export point, of the filesystem. fb_fileid is 0 bytes. | ||
82 | * 1 - 32bit inode number, 32 bit generation number. | ||
83 | * 2 - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number. | ||

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. | ||
