* Initialize the routing table before domains.mpi2015-10-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | The routing table is not an optional component of the network stack and initializing it inside the "routing domain" requires some ugly introspection in the domain interface. This put the rtable* layer at the same level of the if* level. These two subsystem are organized around the two global data structure used in the network stack: - the global &ifnet list, to be used in process context only, and - the routing table which can be read in interrupt context. This change makes the rtable_* layer domain-aware and extends the "struct domain" such that INET, INET6 and MPLS can specify the length of the binary key used in lookups. This allows us to keep, or move towards, AF-free route and rtable layers. While here stop the madness and pass the size of the maximum key length in *byte* to rn_inithead0(). ok claudio@, mikeb@

* Make every subsystem using a radix tree call rn_init() and pass thempi2015-09-041-2/+1
| | | | | | | | | | | | | | | length of the key as argument. This way every consumer of the radix tree has a chance to explicitly initialize the shared data structures and no longer rely on another subsystem to do the initialization. As a bonus ``dom_maxrtkey'' is no longer used an die. ART kernels should now be fully usable because pf(4) and IPSEC properly initialized the radix tree. ok chris@, reyk@
* Use a global table for domains instead of building a list at run time.mpi2015-08-301-2/+2
| | | | | | | As a side effect there's no need to run if_attachdomain() after the list of domains has been built. ok claudio@, reyk@
* Abstract the routing table internals behind an rtable_* API.mpi2015-07-181-10/+3
| | | | | | | | | | Code abusing the radix internals for the routing table should now includes <net/rtable.h> and only deal with "struct rtentry". Code using a radix tree for another purpose can still include <net/radix.h>. Inputs from and ok claudio@, mikeb@

| | | | | | | | | | | | | | To minimise path disruptions, this implements recommendations made in RFC2992 - the hash-threshold mechanism to select paths based on source/destination IP address pairs, and inserts multipath routes in the middle of the route table.
