ip_vs_ftp when loaded can create NAT connections with unknown client port for passive FTP. For such expectations we lookup with cport=0 on incoming packet but it matches the format of the persistence templates causing packets to other persistent virtual servers to be forwarded to real server without creating connection. Later the reply packets are treated as foreign and not SNAT-ed. This patch changes the connection lookup for packets from clients: * introduce IP_VS_CONN_F_TEMPLATE connection flag to mark the connection as template * create new connection lookup function just for templates - ip_vs_ct_in_get * make sure ip_vs_conn_in_get hits only connections with IP_VS_CONN_F_NO_CPORT flag set when s_port is 0. By this way we avoid returning template when looking for cport=0 (ftp) Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S. Miller <davem@davemloft.net> |
