Revision d747a7a51b00984127a88113cdbbc26f91e9d815 authored by WANG Cong on 25 June 2017, 06:50:30 UTC, committed by David S. Miller on 25 June 2017, 16:23:07 UTC
We have to reset the sk->sk_rx_dst when we disconnect a TCP connection, because otherwise when we re-connect it this dst reference is simply overridden in tcp_finish_connect(). This fixes a dst leak which leads to a loopback dev refcnt leak. It is a long-standing bug, Kevin reported a very similar (if not same) bug before. Thanks to Andrei for providing such a reliable reproducer which greatly narrows down the problem. Fixes: 41063e9dd119 ("ipv4: Early TCP socket demux.")
