netfilter: ipvs: Fix inappropriate output of procfs
[ Upstream commit c5504f724c86ee925e7ffb80aa342cfd57959b13 ]
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
