Miller" <davem@...emloft.net>, Jakub Kicinski <kuba@...nel.org>, Christoph Paasch <cpaasch@...le.com>, mptcp@...ts.01.org Subject: [PATCH net 5/5] mptcp: initialize the data_fin field for mpc packets When parsing MPC+data packets we set the dss field, so we must also initialize the data_fin, or we can find stray value there.
