Starting with 2.6.26, there is no loss # of TCP functionality/features under normal conditions. When flood # protections kick in under high unanswered-SYN load, the system # should remain more stable, with a trade off of some loss of TCP # functionality/features (e.g. TCP Window scaling). net.ipv4.tcp_syncookies=1
