Question csf invalid chain


Greetings

I use csf (Centos 6) 64bit and noticed some "invalid" when restarting csf.

from csf -l :

Chain INPUT (policy DROP 0 packets, 0 bytes)
num pkts bytes target prot opt in out source destination

...
....
17 3438 296K INVALID tcp -- !lo * 0.0.0.0/0 0.0.0.0/0

...


and also:

Chain OUTPUT (policy DROP 0 packets, 0 bytes)
num pkts bytes target prot opt in out source destination

...
...

20 3890 5630K INVALID tcp -- * !lo 0.0.0.0/0 0.0.0.0/0

.....

more:

Chain INVALID (2 references)

1 25 1000 INVDROP all -- * * 0.0.0.0/0 0.0.0.0/0 state INVALID



when restarting csf (csf -r):

...
Flushing chain `INVALID'
...
Deleting chain `INVALID'

Flushing chain `INVALID'

Deleting chain `INVALID'

INVALID tcp opt -- in !lo out * 0.0.0.0/0 -> 0.0.0.0/0

INVALID tcp opt -- in * out !lo 0.0.0.0/0 -> 0.0.0.0/0


INVALID tcp opt in !lo out * ::/0 -> ::/0
INVALID tcp opt in * out !lo ::/0 -> ::/0

any idea?

TIA.

That's just a chain named "INVALID".
