Bug is:
xtables -N test
xtables -A FORWARD -j test
xtables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
test all -- anywhere anywhere [0 bytes of unknown target data]
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain test (1 references)
target prot opt source destination
"[0 bytes of unknown target data]" should not be printed in this case.
