After inserting the following IPv4 routers:
0x360AD0A2/30
0x360ADFEC/20
0x360AD082/30
I try to delete the above routes, when delete the second
route(0x360ADFEC/20), the operation fail.
struct radix_node * rn_delete (........)
{
...
/*
* Delete our route from mask lists.
*/
if (netmask != NULL) {
if ((x = rn_addmask(netmask, TRUE, head_off)) == NULL)
return (NULL);
netmask = x->rn_key;
while (tt->rn_mask != netmask)
if ((tt = tt->rn_dupedkey) == NULL)
return (NULL); // rn_delete return here!!!
}
...
}
but, if I delete as the following order, all routers was deleted
successfully:
0x360AD0A2/30
0x360AD082/30
0x360ADFEC/20
so, is it a bug of RADIX?
