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