[2.6.14] ipt_TARPIT vs sysctl_ip_default_ttl.

[PaweÅ Sikora]

Hi,

The ipt_TARPIT module uses sysctl_ip_default_ttl
variable but kernel doesn't export this symbol.

ipt_TARPIT.c:
(...)
        /* Adjust IP TTL */
#ifdef CONFIG_SYSCTL
        nskb->nh.iph->ttl = sysctl_ip_default_ttl;
#else
        nskb->nh.iph->ttl = IPDEFTTL;
#endif
(...)

Finally we get undefined symbol in TARPIT module.
