src: introduce SYNPROXY matching
Add support for "synproxy" statement. For example (for TCP port 8888):
table ip x {
chain y {
type filter hook prerouting priority raw; policy accept;
tcp dport 8888 tcp flags syn notrack
}
chain z {
type filter hook input priority filter; policy accept;
tcp dport 8888 ct state invalid,untracked synproxy mss 1460 wscale 7 timestamp sack-perm
ct state invalid drop
}
}
