# iptables -I INPUT -m conntrack --ctstate UNTRACKED # iptables -L INPUT Chain INPUT (policy DROP) target prot opt source destination all -- anywhere anywhere ctstate (ctstate isn't matching anything.) The problem is that state_mask in 'struct xt_conntrack_mtinfo1' is only 8 bit, but XT_CONNTRACK_STATE_UNTRACKED == 256. Unfortunately, gcc doesn't warn about this for '|=', only for '='. A workaround is to use -m state --state UNTRACKED Looks like we need a conntrack match v2 to fix this? -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
