        There is one "if", we can save CPU :)

        Hm, how can I reply to attached text. Anyway, I'll try.

        The OOPS seems to be in this code:

int ipfw_output_check(struct firewall_ops *this, int pf, struct device *dev,
                      void *phdr, void *arg, struct sk_buff **pskb)
{
        /* Locally generated bogus packets by root. <SIGH>. */
        if (((struct iphdr *)phdr)->ihl * 4 < sizeof(struct iphdr)
            || (*pskb)->len < sizeof(struct iphdr))
                return FW_ACCEPT;
        return ip_fw_check(phdr, dev->name,
                           arg, IP_FW_OUTPUT_CHAIN, *pskb, SLOT_NUMBER(), 0);
}

        I.e. in IP_FW_OUTPUT_CHAIN which is:

(ip_fw_chains->next->next)

        By some reason ip_fw_chains->next==1. For now I don't have idea
why.

        Do you play any games with creating new chains, etc? If yes,
show some names.

        What is the binutils version? ld -v, CPU?


Regards
