* 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@

* 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@

* When pf modifies a TCP packet, it sets the M_TCP_CSUM_OUT flag inbluhm2015-09-111-3/+3
| | | | | | | | | | | | | | | | | the mbuf packet header. If the packet and is later dropped in ip6_forward(), the TCP mbuf is copied and passed to icmp6_error(). IPv6 uses m_copym() and M_PREPEND() which preserve the packet header. The inherited M_TCP_CSUM_OUT flag generates ICMP6 packets with an incorrect checksum. So reset the csum_flags when packets are generated by icmp6_reflect() or icmp6_redirect_output(). IPv4 does m_copydata() into a fresh mbuf. There m_inithdr() clears the packet header, so the problem does not occur. But setting the csum_flags explicitly also makes sense for icmp_send(). Do not or M_ICMP_CSUM_OUT to a value that is 0 because of some function calls before. OK mpi@ lteo@

| | | | | | | | | 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.

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@
