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