`iptables -p all' uses 0 to match all protocols, while the conntrack subsystem uses 255. We still need `-p all' to attach the custom timeout policies for the generic protocol tracker. Moreover, we may use `iptables -p sctp' while the SCTP tracker is not loaded. In that case, we have to default on the generic protocol tracker. Another possibility is `iptables -p ip' that should be supported as well. This patch makes sure we validate all possible scenarios. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
