* Use rtisivalid(9) to check if the given (cached) route can be used.mpi2015-10-131-8/+6
| | | | | | | | | | | | | | | | | | Note that after calling rtalloc(9) we only check if a route has been returned or not and do not check for its validity. This cannot be improved without a massive refactoring. The kernel currently *do* use !RTF_UP route due to a mismatch between the value of ifp->if_link_state and the IFF_UP|IFF_RUNNING code. I'd explain the RTF_UP flag as follow: . If a cached route entry w/o RTF_UP is passed to ip{6,}_output(), . call rtalloc(9) to see if a better entry is present in the tree. This is enough to support MPATH and route cache invalidation. ok bluhm@

| | | | | | | | | In all but two calls NULL is passed and in the other 2 cases the ifp is only used to maybe feed it to in6_selecthlim() to select the hoplimit for the link. Since in6_embedscope() only works on link-local addresses it does not matter what hop limit we select since the destination is directly reachable. OK florian@ mpi@

* Convert ip{,6}_output() (cached) route entry checks to rtisvalid(9).mpi2015-09-031-8/+6
| | | | | | | | | This introduces a behavior change as we now reject !RTF_UP routes to output packets. This stricter check exposed a bug in the setup of new routes and was the reason for the previous revert. This should be now fixed by r1.229 of sys/net/route.c . ok bluhm@
* Revert the two uses of rtisvalid(9) for the moment, it breaks dhclient(8)mpi2015-09-021-6/+8
| | | | | | | | configured networks on RAMDISK kernels. The problem is that the default route installed by dhclient(8) does not have the RTF_UP flag in this environement and rtisvalid(9) doesn't allow you to use a RTF_DOWN route.

* Use an interface index instead of a pointer for multicast options.mpi2014-12-171-5/+4
| | | | | | | | | | | | Output interface (port) selection for multicast traffic is not done via route lookups. Instead the output ifp is registred when setsockopt(2) is called with the IP{V6,}_MULTICAST_IF option. But since there is no mechanism to invalidate such pointer stored in a pcb when an interface is destroyed/removed, it might lead your kernel to fault. Prevent a fault upon resume reported by frantisek holop, thanks! ok mikeb@, claudio@
