KUWAZAWA Takuya d815f4efbb netfilter: ipvs: Fix inappropriate output of procfs 
[ Upstream commit c5504f724c ]

Information about ipvs in different network namespace can be seen via procfs.

How to reproduce:

  # ip netns add ns01
  # ip netns add ns02
  # ip netns exec ns01 ip a add dev lo 127.0.0.1/8
  # ip netns exec ns02 ip a add dev lo 127.0.0.1/8
  # ip netns exec ns01 ipvsadm -A -t 10.1.1.1:80
  # ip netns exec ns02 ipvsadm -A -t 10.1.1.2:80

The ipvsadm displays information about its own network namespace only.

  # ip netns exec ns01 ipvsadm -Ln
  IP Virtual Server version 1.2.1 (size=4096)
  Prot LocalAddress:Port Scheduler Flags
    -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
  TCP  10.1.1.1:80 wlc

  # ip netns exec ns02 ipvsadm -Ln
  IP Virtual Server version 1.2.1 (size=4096)
  Prot LocalAddress:Port Scheduler Flags
    -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
  TCP  10.1.1.2:80 wlc

But I can see information about other network namespace via procfs.

  # ip netns exec ns01 cat /proc/net/ip_vs
  IP Virtual Server version 1.2.1 (size=4096)
  Prot LocalAddress:Port Scheduler Flags
    -> RemoteAddress:Port Forward Weight ActiveConn InActConn
  TCP  0A010101:0050 wlc
  TCP  0A010102:0050 wlc

  # ip netns exec ns02 cat /proc/net/ip_vs
  IP Virtual Server version 1.2.1 (size=4096)
  Prot LocalAddress:Port Scheduler Flags
    -> RemoteAddress:Port Forward Weight ActiveConn InActConn
  TCP  0A010102:0050 wlc
