37 * Enhanced OS X and Netatalk compatibility
38 * ========================================
39 *
40 * This modules takes advantage of vfs_streams_xattr and
41 * vfs_catia. VFS modules vfs_fruit and vfs_streams_xattr must be
42 * loaded in the correct order:
43 *
44 * vfs modules = catia fruit streams_xattr
45 *
46 * The module intercepts the OS X special streams "AFP_AfpInfo" and
47 * "AFP_Resource" and handles them in a special way. All other named
48 * streams are deferred to vfs_streams_xattr.
49 *
50 * The OS X client maps all NTFS illegal characters to the Unicode
51 * private range. This module optionally stores the charcters using
52 * their native ASCII encoding using vfs_catia. If you're not enabling
53 * this feature, you can skip catia from vfs modules.
54 *
55 * Finally, open modes are optionally checked against Netatalk AFP
56 * share modes.
57 *
58 * The "AFP_AfpInfo" named stream is a binary blob containing OS X
59 * extended metadata for files and directories. This module optionally
60 * reads and stores this metadata in a way compatible with Netatalk 3
61 * which stores the metadata in an EA "org.netatalk.metadata". Cf
62 * source3/include/MacExtensions.h for a description of the binary
63 * blobs content.
64 *
65 * The "AFP_Resource" named stream may be arbitrarily large, thus it
66 * can't be stored in an xattr on most filesystem. ZFS on Solaris is
67 * the only available filesystem where xattrs can be of any size and
68 * the OS supports using the file APIs for xattrs.
69 *
70 * The AFP_Resource stream is stored in an AppleDouble file prepending
71 * "._" to the filename. On Solaris with ZFS the stream is optionally
72 * stored in an EA "org.netatalk.resource".
73 *
74 *
75 * Extended Attributes
76 * ===================
77 *
78 * The OS X SMB client sends xattrs as ADS too. For xattr interop with
79 * other protocols you may want to adjust the xattr names the VFS
80 * module vfs_streams_xattr uses for storing ADS's. This defaults to
81 * user.DosStream.ADS_NAME:$DATA and can be changed by specifying
82 * these module parameters:
83 *
84 * streams_xattr:prefix = user.
85 * streams_xattr:store_stream_type = false
86 *
87 *
88 * TODO
89 * ====
90 *
91 * - log diagnostic if any needed VFS module is not loaded
92 * (eg with lp_vfs_objects())
93 * - add tests
