commit fdcaa4af5e70e2d984c9620a09e9dade067f2620

nfsd4: readdirplus shouldn’t return parent of export<\/p>\n

commit 51b2ee7d006a736a9126e8111d1f24e4fd0afaa6 upstream.<\/p>\n

If you export a subdirectory of a filesystem, a READDIRPLUS on the root
\n of that export will return the filehandle of the parent with the ".."
\n entry.<\/p>\n

The filehandle is optional, so let’s just not return the filehandle for
\n ".." if we’re at the root of an export.<\/p>\n

Note that once the client learns one filehandle outside of the export,
\n they can trivially access the rest of the export using further lookups.<\/p>\n

However, it is also not very difficult to guess filehandles outside of
\n the export. So exporting a subdirectory of a filesystem should
\n considered equivalent to providing access to the entire filesystem. To
\n avoid confusion, we recommend only exporting entire filesystems.<\/p>\n
