flushing & deleting non existing chains

[gopi bhimavarapu <gopimallikharjun@xxxxxxxxx>]

Hi

I was trying to flush a chain, delete all the rules and delete the chain before creation of the chain.
This approach worked fine in iptables-1.4.0, but seems like in iptables-1.4.12.2, we cannot flush a non existing chain.
Is there any change in the expected behavior ?


Snippet below works fine in 1.4.0 (using iptables-restore), but complains in iptables-1.4.12.2


*filter
:FORWARD DROP [0:0]
-F chain_tun_0_
 -D FORWARD -o tun_0_+ -j chain_tun_0_
 -D FORWARD -i tun_0_+ -j chain_tun_0_
-X chain_tun_0_
:chain_tun_0_ - [0:0]
 -I chain_tun_0_ -j DROP
 -I FORWARD -i tun_0_+ -j chain_tun_0_
 -I FORWARD -o tun_0_+ -j chain_tun_0_
 -I chain_tun_0_ --protocol all -o tun_0_+    -j ACCEPT
 -I chain_tun_0_ --protocol all -i tun_0_+    -j ACCEPT
 -o ext0 -I chain_tun_0_ -j DROP
 -i ext0 -I chain_tun_0_ -j DROP
COMMIT


Regards,
Gopi
