reflect_filter_rate_limit_check()

bool reflect_filter_rate_limit_check

(

struct initial_packet_rate_limit *

irl

checks if the connection is still allowed to connect under the rate limit.

This also increases the internal counter at the same time

reflect_filter_rate_limit_decrease()

void reflect_filter_rate_limit_decrease

(

struct initial_packet_rate_limit *

decreases the counter of initial packets seen, so connections that successfully completed the three-way handshake do not count against the counter of initial connection attempts
