Currently the sysctl of netfilter proto is not isolated, so when changing proto's sysctl in container will cause the host's sysctl be changed too. it's not expected. This patch set adds the namespace support for netfilter protos. impletement four pernet_operations to register sysctl and initial pernet data for proto. -ipv4_net_ops is used to register tcp4(compat), udp4(compat),icmp(compat),ipv4(compat). -ipv6_net_ops is used to register tcp6,udp6 and icmpv6. -sctp_net_ops is used to register sctp4(compat) and sctp6. -udplite_net_ops is used to register udplite4 and udplite6 extern l[3,4]proto (sysctl) register functions to make them support namespace. finailly add namespace support for cttimeout. Changes from v2: re-split patchset to make compilation success.
