Subject: [PATCH] ipv6: nullify ipv6_ac_list and ipv6_fl_list when
creating new socket
To: "netdev@vger.kernel.org" <netdev@vger.kernel.org>,
"davem@davemloft.net" <davem@davemloft.net>

ipv6_ac_list and ipv6_fl_list from listening socket are inadvertently
shared with new socket created for connection.
