2014-04-10Retire rtinit() an use rt_ifa_add(9) and rt_ifa_del(9) to manageMartin Pieuchot
connected routes to prefixes/hosts. Since the introduction of rt_ifa_addloop(9) and rt_ifa_delloop(9), rtinit() was just a wrapper, so use the underlying functions directly and document them. Inputs from and ok mikeb@, manpage tweaks from jmc@
2014-03-20Do not pull <sys/tree.h> unconditionally in <net/if.h>, only the addressMartin Pieuchot
tree and the 80211 nodes need it. ok henning@, mikeb@
2014-03-19Since in{,6}_ifdetach() take care of removing the IPv4/6 addressesMartin Pieuchot
from the per-ifp list when an interface is destroyed/removed the only address left on the list at this point is the link-layer one. So remove the custom loop and its associated hack for the link-layer address and simply call if_free_sadl(). As a side effect, this should fix any scenario where if_alloc_sadl() is called multiple time since the first link-layer address allocated was never removed from the per-ifp list.

2013-11-28Change the way protocol multicast addresses are linked to an interface.Martin Pieuchot
Instead of linking multicast records to the first configured address of the corresponding protocol, making this address and its position in the global list special, add them to a new list directly linked to the interface descriptor. This new multicast address list is similar to the address list, all its elements contain a protocol agnostic part. This design allows us to be able to join a multicast group without necessarily having a configured address. That means IPv6 multicast kludges are no longer needed. Another benefit is to be able to add and remove an IP address from an interface without worrying about multicast records. That means that the global IPv4 list is no longer needed since the first configured address of an interface is no longer special. This new list might also be extended in the future to contain the link-layer addresses used to configure hardware filters. Tested by sthen@ and weerd@, ok mikeb@

While here add a comment explaining detach hooks' order of execution when destroying/detaching an interface.
2013-11-11Replace most of our formating functions to convert IPv4/6 addresses fromMartin Pieuchot
network to presentation format to inet_ntop(). The few remaining functions will be soon converted. ok mikeb@, deraadt@ and moral support from henning@

Started by claudio@ for IPv4, lots of heavy work by sperreault@ My part started at s2k11, continued at n2k12, g2k12, c2k12 and n2k13. Lots of help and hints from claudio and bluhm OK claudio@, bluhm@

2013-10-19in order to make our life a tad easier and prevent rogue accessesMike Belopuhov
to the routing table from the hardware interrupt context defer the if_link_state_change to the process context. a token (an interface index) is passed to the workq in order to make sure that if the interface would be gone by the time syswq goes around to run the task it would just fall through. ok henning, mpi, deraadt, claudio

2013-10-19When we attach an interface, do not try to reuse the last index toMartin Pieuchot
limit the possible races related to unscheduled task, or anything else, relying on an unique index. I say "limit" here because a race can still occurs if you run out of indexes and jump back to 1. A generation number can be added later to avoid this problem. ok deraadt@, claudio@, krw@, mikeb@, "I can live with it" reyk@
2013-10-17The header file netinet/in_var.h included netinet6/in6_var.h. ThisAlexander Bluhm
created a bunch of useless dependencies. Remove this implicit inclusion and do an explicit #include <netinet6/in6_var.h> when it is needed. OK mpi@ henning@
2013-10-09Introduce in_ifdetach() a function to remove all the IPv4 addressesMartin Pieuchot
of an interface, named after its IPv6 equivalent. Make use of it instead of removing addresses by hand when detaching or destroying an interface. As a bonus, multicast records linked to the just divorced^Wdetached interface are no longer leaked. No objection from the gang, ok mikeb@
2013-09-17Change vlan(4) detach procedure to not use a hook but a list of vlansMartin Pieuchot
on the parent interface. This is similar to what bridge(4), trunk(4) or carp(4) are doing and allows us to get rid of the detachhook. ok reyk@, mikeb@

depends on this feature, discussed with claudio@.

2012-10-05Point an interface directly to its bridgeport configuration, insteadCamiel Dobbelaar
of to the bridge itself. This is ok, since an interface can only be part of one bridge, and the parent bridge is easy to find from the bridgeport. This way we can get rid of a lot of list walks, improving performance and shortening the code. ok henning stsp sthen reyk
2012-09-19Make rt_lookup return a pointer to an rtentry struct instead ofBret Lambert
to a radix_node struct. The radix tree pushdown continues. ok claudio@
2012-09-19More radix internals pushdown; place rn_mpath_next, which accepts andBret Lambert
returns radix_node pointers, inside a new rt_mpath_next, which accepts and returns rtentry pointers, and start using that instead. ok claudio@
2012-09-18Wrap rtable_add() and rtable_l2set() calls inside ifioctl() inside softnet,Bret Lambert
as functions that modify routing information shouldn't be interruptable by network traffic. Also make sure that both of those functions assert that they are called at softnet. I'm reasonably sure that there shouldn't be any, but if there is any codepath that was missed, we're going to be here for another 4 days to deal with any fallout. While here, move the multitude of "int s" declarations inside ifioctl to the beginning of the function. okay claudio@

cleaner to access the first member via ia_ifa instead of casting. No binary change. ok henning@ krw@
