Hi,
Current dnsmasq (tried from 2.62 onwards) doesn't reply to router
solicits. I think I found the problem.
This is from radv.c from HEAD (commit 35239a30):
-------
205 parm.other = 0;
206 parm.found_context = 0;
parm.found_context gets initialized here.
207 parm.if_name = iface_name;
208 parm.first = 1;
209
210 /* set tag with name == interface */
211 iface_id.net = iface_name;
212 iface_id.next = NULL;
213 parm.tags = &iface_id;
214
215 for (context = daemon->ra_contexts; context; context = context->next)
216 {
217 context->flags &= ~CONTEXT_RA_DONE;
218 context->netid.next = &context->netid;
219 }
220
221 if (!iface_enumerate(AF_INET6, &parm, add_prefixes) ||
222 !parm.found_context)
223 return;
----
If parm.found_context is zero, the function just returns.
iface_enumerate is the only function called, and it doesn't touch
param.found_context. So send_ra always returns.
Removing the "!parm.found_context" from that if-statement in line 222
makes dnsmasq answer to RS again.
Am I missing something?
Cheers,
Kaspar
