Pali Rohár 7b222d6cb8 cifs: Fix buffer overflow when parsing NFS reparse points
commit e2a8910af01653c1c268984855629d71fb81f404 upstream.

ReparseDataLength is sum of the InodeType size and DataBuffer size.
So to get DataBuffer size it is needed to subtract InodeType's size from
ReparseDataLength.

Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer
at position after the end of the buffer because it does not subtract
InodeType size from the length. Fix this problem and correctly subtract
variable len.

Member InodeType is present only when reparse buffer is large enough. Check
for ReparseDataLength before accessing InodeType to prevent another invalid
memory access.

Major and minor rdev values are present also only when reparse buffer is
large enough. Check for reparse buffer size before calling reparse_mkdev().

Fixes: d5ecebc490 ("smb3: Allow query of symlinks stored as reparse points")

[use variable name symlink_buf, the other buf->InodeType accesses are
not used in current version so skip]
