net ipv4: Convert ipv4.ip_local_port_range to be per netns v3
- Move sysctl_local_ports from a global variable into struct netns_ipv4. - Modify inet_get_local_port_range to take a struct net, and update all of the callers. - Move the initialization of sysctl_local_ports into sysctl_net_ipv4.c:ipv4_sysctl_init_net from inet_connection_sock.c v2: - Ensure indentation used tabs - Fixed ip.h so it applies cleanly to todays net-next v3: - Compile fixes of strange callers of inet_get_local_port_range. This patch now successfully passes an allmodconfig build. Removed manual inlining of inet_get_local_port_range in ipv4_local_port_range Originally-by: Samya <samya@twitter.com> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: "Eric W.
