[Olsr-dev] advanced policy routing patch

[Sven-Ola Tuecke]

Hi otti,

your patch will not apply (at least, you diffed' a .gz by accident). This 
patch is against kamikaze-cvs? That may be rather old anyhow. You may retry 
it against olsrd-cvs.

And I don't get it - in what scenario an extra policy defroute will help 
here? a) user wants inet from the mesh or b) user supplies inet to the mesh 
or c) user confused by polrouting and fiddles with different default routes 
too much? Did you notice the following passage in src/linux/kernel_routes.c?

#else /* !LINUX_POLICY_ROUTING */
 if (0 == rt->rt_dst.prefix_len && 253 > olsr_cnf->rttable)
 {
  /*
   * Users start whining about not having internet with policy
   * routing activated and no static default route in table 254.
   * We maintain a fallback defroute in the default=253 table.
   */
  olsr_netlink_route(rt, AF_INET, 253, RTM_NEWROUTE);
 }
 return olsr_netlink_route(rt, AF_INET, olsr_cnf->rttable, RTM_NEWROUTE);
#endif /* LINUX_POLICY_ROUTING */
