From: YOSHIFUJI Hideaki Tetsuo Handa told me that connect(2) with TCPv6 socket almost always took a few minutes to return when we did not have any ports available in the range of net.ipv4.ip_local_port_range. The reason was that we used incorrect seed for calculating index of hash when we check established sockets in __inet6_check_established(). Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S.
