They all stay in SYN_RECV state. If I understand right, something
like this will show:

netstat -n | grep SYN_RECV | grep :80 | wc -l

How these connections are different from ones in real SYN_RECV
state then? I.e., how one is expected to distinguish them from
connections not yet passed 3-way handhake?

AFAIK, there is no way to distinguish them.

Not a problem at all, till it’s noticeable lower than
tcp_max_syn_backlog.

Ok thanks
