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