Subject: [PATCH 3.14 07/37] Fix problem recognizing symlinks
Date: Tue,  7 Oct 2014 16:19:24 -0700	[thread overview]
Message-ID: <20141007231827.292818207@linuxfoundation.org> (raw)
In-Reply-To: <20141007231827.043235686@linuxfoundation.org>

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Steve French <smfrench@gmail.com>

commit 19e81573fca7b87ced7701e01ba164b968d929bd upstream.

Changeset eb85d94bd introduced a problem where if a cifs open
fails during query info of a file we
will still try to close the file (happens with certain types
of reparse points) even though the file handle is not valid.

In addition for SMB2/SMB3 we were not mapping the return code returned
by Windows when trying to open a file (like a Windows NFS symlink)
which is a reparse point.
