40 : * Enhanced OS X and Netatalk compatibility
41 : * ========================================
42 : *
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:
46 : *
47 : * vfs modules = catia fruit streams_xattr
48 : *
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.
52 : *
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.
57 : *
58 : * Finally, open modes are optionally checked against Netatalk AFP
59 : * share modes.
60 : *
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
66 : * blobs content.
67 : *
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.
72 : *
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".
76 : *
77 : *
78 : * Extended Attributes
79 : * ===================
80 : *
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:
86 : *
87 : * streams_xattr:prefix = user.
88 : * streams_xattr:store_stream_type = false
89 : *
90 : *
91 : * TODO
92 : * ====
93 : *
94 : * - log diagnostic if any needed VFS module is not loaded
95 : * (eg with lp_vfs_objects())
96 : * - add tests
