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