33 * Enhanced OS X and Netatalk compatibility
34 * ========================================
36 * This modules takes advantage of vfs_streams_xattr and
37 * vfs_catia. VFS modules vfs_fruit and vfs_streams_xattr must be
38 * loaded in the correct order:
40 * vfs modules = catia fruit streams_xattr
42 * The module intercepts the OS X special streams "AFP_AfpInfo" and
43 * "AFP_Resource" and handles them in a special way. All other named
44 * streams are deferred to vfs_streams_xattr.
46 * The OS X client maps all NTFS illegal characters to the Unicode
47 * private range. This module optionally stores the charcters using
48 * their native ASCII encoding using vfs_catia. If you're not enabling
49 * this feature, you can skip catia from vfs modules.
51 * Finally, open modes are optionally checked against Netatalk AFP
54 * The "AFP_AfpInfo" named stream is a binary blob containing OS X
55 * extended metadata for files and directories. This module optionally
56 * reads and stores this metadata in a way compatible with Netatalk 3
57 * which stores the metadata in an EA "org.netatalk.metadata". Cf
58 * source3/include/MacExtensions.h for a description of the binary
61 * The "AFP_Resource" named stream may be arbitrarily large, thus it
62 * can't be stored in an xattr on most filesystem. ZFS on Solaris is
63 * the only available filesystem where xattrs can be of any size and
64 * the OS supports using the file APIs for xattrs.
66 * The AFP_Resource stream is stored in an AppleDouble file prepending
67 * "._" to the filename. On Solaris with ZFS the stream is optionally
68 * stored in an EA "org.netatalk.ressource".
74 * The OS X SMB client sends xattrs as ADS too. For xattr interop with
75 * other protocols you may want to adjust the xattr names the VFS
76 * module vfs_streams_xattr uses for storing ADS's. This defaults to
77 * user.DosStream.ADS_NAME:$DATA and can be changed by specifying
78 * these module parameters:
80 * streams_xattr:prefix = user.
81 * streams_xattr:store_stream_type = false
87 * - log diagnostic if any needed VFS module is not loaded
88 * (eg with lp_vfs_objects())
