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
