2016-11-14Automatically create a default lo(4) interface per rdomain.Martin Pieuchot
In order to stop abusing lo0 for all rdomains, a new loopback interface will be created every time a rdomain is created. The unit number will be the same as the rdomain, i.e. lo1 will be attached to rdomain 1. If this loopback interface is already in use it wont be possible to create the corresponding rdomain. In order to know which lo(4) interface is attached to a rdomain, its index is stored in the rtable/rdomain map. This is a long overdue since the introduction of rtable/rdomain. It also fixes a recent regression due to resetting the rdomain of an incoming packet reported by semarie@, Andreas Bartelt and Nils Frohberg. ok claudio@

2016-06-27Implement IPV6_MINHOPCOUNT support.Jeremie Courreges-Anglas
Useful to implement GTSM support in daemons such as bgpd(8). Diff from 2013 revived by renato@. Input from bluhm@, ok bluhm@ deraadt@
2016-06-15With the introduction of ip6_output_ipsec_lookup() we didn't exit theFlorian Obser
loop when we worked out that no IPsec is needed which led to a NULL de-ref on the next iteration. Fix this by making the code more similar to the IPv4 case. Found the hard way by me, OK mpi@

2016-05-19Remove sysctl net.inet6.ip6.v6onlyJeremie Courreges-Anglas
This sysctl is a no-op, read-only since it was introduced. There are no plans to support IPv4-mapped addresses on OpenBSD, thus this sysctl is meaningless. Noticed by djm@, ok claudio@ mpi@ sthen@ henning@
2016-04-29Do not allow to change the routing table of a bound socket. ThisAlexander Bluhm
is not intended and will behave unexpectedly if the address is already used in another domain. It did not work anyway, as the PCB ended in the wrong hash bucket after changing the rtable. Fail with EBUSY if the socket is already bound and rehash the PCB if its rtable changes. input claudio@; OK mpi@

2015-11-29Use if_get() rather than dereferencing rt_ifp in ip6_getpmtu().Martin Pieuchot

2015-09-13Get the default loopback interface pointer just after doing a routeMartin Pieuchot
lookup to ensure pf_test() is called with the same interface in the input annd output path for local traffic. Fix a regression reported by Heiko Zimmermann on bugs@, thanks! ok mikeb@, claudio@
2015-09-12Stop overwriting the rt_ifp pointer of RTF_LOCAL routes with lo0ifp.Martin Pieuchot
Use instead the RTF_LOCAL flag to loop local traffic back to the corresponding protocol queue. With this change rt_ifp is now always the same as rt_ifa->ifa_ifp. ok claudio@
2015-09-12Introduce if_input_local() a function to feed local traffic back toMartin Pieuchot
the protocol queues. It basically does what looutput() was doing but having a generic function will allow us to get rid of the loopback hack overwwritting the rt_ifp field of RTF_LOCAL routes. ok mikeb@, dlg@, claudio@

2015-06-16Store a unique ID, an interface index, rather than a pointer to theMartin Pieuchot
receiving interface in the packet header of every mbuf. The interface pointer should now be retrieved when necessary with if_get(). If a NULL pointer is returned by if_get(), the interface has probably been destroy/removed and the mbuf should be freed. Such mechanism will simplify garbage collection of mbufs and limit problems with dangling ifp pointers. Tested by jmatthew@ and krw@, discussed with many. ok mikeb@, bluhm@, dlg@
