Ruslan Ermilov b5e819ec23 Apply TCP_EXPIRE_CONNECTED (86400 seconds) timeout only to established ... connections, after SYN packets were seen from both ends. Before this, it would get applied right after the first SYN packet was seen (either from client or server). With broken TCP connection attempts, when the remote end does not respond with SYNACK nor with RST, this resulted in having a useless (ie, no actual TCP connection associated with it) TCP link with 86400 seconds TTL, wasting system memory. With high rate of such broken connection attempts (for example, remote end simply blocks these connection attempts with ipfw(8) without sending RST back), this could result in a denial-of-service.
