* If intra area prefixes move from one router to another router, cloning routesfriehm2018-07-101-4/+23
| | | | | | | | | | | may become gateway routes and contrary. The kernel does not allow to change the flags RTF_GATEWAY / RTF_CLONING in RTM_CHANGE messages, but ospf6d tried this anyway. The result is a broken route. Instead of modifying such routes remove the old route and insert a new one. Thanks to Raimund Specht for reporting the problem and testing the fix. OK claudio@

| | | | | | | Also remove the RTF_UP flag from hdr.rtm_flags in send_rtmsg() since ospfd and bgpd don't set the flag. OK bluhm@ claudio@

* Let rde and ospfe know about all IFINFO messages (eg an interface MTU change).jca2016-12-221-7/+7
| | | | | | | The parent now passes all IFINFO messages down to the children, then looks whether he has any work to do. Same idea as ospfd. ok benno@ claudio@

Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

Mainly used for redistribute default since on default free routers we need to have a fake route now.

* The current code in ospf6d kroute tries to read the scope of thebluhm2012-09-201-9/+18
| | | | | | | route from the gateway's scope id. That does not work as the kernel provides the scope id via the kame hack instead of the sin6_scope_id field of the sockaddr_in6. Call recoverscope() to fix that. OK claudio@

* Rework the distribution of link state and iface FSM state changes.claudio2011-07-071-3/+6
| | | | | Link state changes are sent from the parent to both childs and iface FSM state changes are sent from the ospfe to the rde.
* Only send interface address changes to the ospfe/rde if the interfaceclaudio2011-07-071-15/+21

* Same fix as previously commited to ospfd. Ensure that kr_redistribute()claudio2010-10-141-5/+6

* Redistributing the default route with ospf6d did not work correctly.bluhm2010-08-221-6/+5
| | | | | | | | | - kroute.c may not ignore the default route. - Use the ROUNDUP macro from route/show.c as this one is also correct for netmask with prefixlen 0. - Implement ospf_redistribute and the redistribute parser like ospfd. ok claudio@

Upon this event, originate a new link-lsa in ospfe. In rde a new intra-area-prefix-lsa is generated when a link-lsa appears or goes away. ok claudio@; ok and test stsp@
* If there is no next hop but an interface index, create a cloningbluhm2010-06-281-1/+22
| | | | | | | | route. This happens when we learn from another router that a directly attached link has a prefix for which we have no address configured at the interface. In this case, we should do neighbor discovery to directly reach the hosts with that prefix on the link. ok claudio@
* The "dispatch_rtmsg no nexthop" error was emitted in wrong casesbluhm2010-06-121-2/+2

This needs to be fixed but my quota of IPv6 insanity is already used for today. Workaround for now. My simple testsetup is now actually able to install the first ospf6d learned routes in the kernel.
