* Factorize various duplicated chunks of (old and horrible) code, checkingmpi2015-01-081-13/+23
| | | | | | | | | | | | | | | | | | | | | | | | | for the validity of a given outgoing route entry into a single function. This change is inspired from FreeBSD r111767. The function introduced here, rt_checkgate(), should hopefully die in a near future. Why should it die? Well, it is way too late to do such validity checks: if your kernel can ends up in ether_output() with an invalid route, please do not let it try to find a new one that might do the job. Go read this function if you're wondering why you're getting messages like: "arpresolve: X.X.X.X: route without link local address" Since this horrible logic has survived 20 years of copy & past and small modifications for workarounds without a single clear commit message, let's assume it is full of dragons and try to play safe. This factorization is not intended to change any behavior. With much inputs from bluhm@, tested by weerd@ and florian@ on setups with p2p IPv6 interfaces. ok bluhm@, benno@, florian@

* Revert the addition of broadcast addresses, it apparently also corruptsmpi2014-08-261-13/+1

* When a local route entry is added for an ifa having a broadcast address,mpi2014-08-191-1/+13
| | | | | | | | | | | | | | | also adds a broadcast entry flagged with RTF_BROADCAST. Prior to this change broadcast entries were simple clonned ARP entries, that would be deleted once their timer expired since they would always be incomplete. With this change they are now persistant and identifiable with a new flag. Committing early to be able to deal with any potential fallout before we start relying on this. ok florian@, mikeb@, henning@
* Use the RTF_LOCAL flag instead of abusing the RTF_LLINFO flag whenmpi2014-08-111-2/+2

| | | | | | | | | | | | | | | | machine and restore the original behavior of RTM_ADD and RTM_DELETE by always generating one message per locally configured address. This time, make sure the local route is removed during an address change, since at least pppoe(4) do some funky magics with wildcard addresses that might corrupt the routing tree, as found by naddy@ Also do not add a local route if the specified address is 0.0.0.0, to prevent a tree corruption, as found by guenther@. Putting this in now so that it gets tested, claudio@ agrees. Please contact me if you find any route-related regression caused by this change.

* "struct pkthdr" holds a routing table ID, not a routing domain one.mpi2014-04-141-4/+4
| | | | | | | | | | | | | | Avoid the confusion by using an appropriate name for the variable. Note that since routing domain IDs are a subset of the set of routing table IDs, the following idiom is correct: rtableid = rdomain But to get the routing domain ID corresponding to a given routing table ID, you must call rtable_l2(9). claudio@ likes it, ok mikeb@

* Stop mixing interface address flags with routing entry ones.mpi2014-03-271-2/+1
| | | | | | | | | | Instead of always copying ifa_flags to the routing entry flags when creating a route by calling rtinit(), explicitly pass the RTF_CLONING flag when required. This means ifa_flags are now *only* used to check if an address has an associated route that was created by the kernel auto-magically. ok benno@

* Convert the route expire timestamp in kernel and routing messagebluhm2013-10-311-2/+2
| | | | | | | | | | | | | to 64 bit. Increase the routing message version from 4 to 5. Add a small compatibility layer that allows to set routes with old user land and new kernel. Old kernel with new user land does not work. The compatibility layer ist not perfect, but it allows to configure addresses with old ifconfig and new kernel. Route get also works in this setup. dhclient hangs as messages for interface address changes with old version are not generated. OK claudio@
