Makes non-IPv6 kernels build again
blame and ok henning@

alternate routing table and separate them from other interfaces in distinct
routing tables. The same network can now be used in any doamin at the same
time without causing conflicts.
This diff is mostly mechanical and adds the necessary rdomain checks accross
net and netinet. L2 and IPv4 are mostly covered still missing pf and IPv6.
input and tested by jsg@, phessler@ and reyk@. "put it in" deraadt@

ifconfig em0 -inet6
deletes all v6 addresses including link-local and prevents new ones from
being added.
ifconfig em0 inet6 <addr>
re-enables v6, brings the link local back and adds optional <addr>

to save some space in the kernel. Although there are deeper issues with
interface attachment, this diff was not meant to address those, just to
shave some space ;)

levels. This will allow for platforms where soft interrupt levels do not
map to real hardware interrupt levels to have soft ipl values overlapping
hard ipl values without breaking spl asserts.

and I'm currently unable to find the cause of this. Time is running out so
workaround it for now. OK deraadt.

As a bonus it eliminates casting from pointer to int.

added without an expilict priority. This allows to specify less prefered
interfaces that will only take over if the primary interface loses link.

Use a 1 tick timeout() to determine if the kernel even manages to get
below softclock (from an old diff by mpf). If our timeout comes late,
reduce the high water marks (to half) for all network interfaces, thus
starving them of future packet allocations for their RX rings. For a
few ticks longer, also block the high water marks from rising even if
RX ring empty conditions would prod us to do so.
Cards may start dropping some packets off the end of their smaller RX
rings, but we were not able to do the work required in any case. With
less interrupt time and mbuf movement, the system finds time to make
progress at the network queues. Userland even gets to run.
A x40 tuned to 600MHz shows no real reduction in performance. But a
soekris has a working console now.

watermark for mbuf cluster allocations.
this is necessary for things like bge which cannot cope with less than a
certain number of pkts on the ring.

the per ifp cluster allocator. should prevent the hwm being raised
innapropriately when a driver fills its rx ring for the first time.

allocators again.

ok dlg

but don't do that in m_free() as that will cause a double loop behaviour when
called via m_freem().
OK dlg@, deraadt@

of. currently limited to MCLBYTES (2048 bytes) and 4096 bytes until pools
can allocate objects of sizes greater than PAGESIZE.
this allows drivers to ask for "jumbo" packets to fill rx rings with.
the second half of this change is per interface mbuf cluster allocator
statistics. drivers can use the new interface (MCLGETI), which will use
these stats to selectively fail allocations based on demand for mbufs. if
the driver isnt rapidly consuming rx mbufs, we dont allow it to allocate
many to put on its rx ring.
drivers require modifications to take advantage of both the new allocation
semantic and large clusters.
this was written and developed with deraadt@ over the last two days

which are considered down will no be marked ~RTF_UP and so multipath routing
will start to work as expected and not pump 50% of the traffic to nirvana.
Most of the magic happens in rn_mpath_reprio() which fiddles with the
routing table internals. The rest is more straight forward.

not only over routes of the same prio. This makes it possible to modify
rt_mpath_matchgate() so that if only gateway is specified without a specific
priority it will scan the full list and not only the first routes.
This is also needed for upcoming link state tracking.

addressing in IPv6 likes to do ifp = ifindex2ifnet[ifindex] without properly
checking if the ifindex is valid. As a side-effect this solves parts of
PR 5981. Debugged by jsing@. OK jsing@, deraadt@

a /0 netmask so check fot that too. tested by david@ OK henning@

get hung in nfs_reconnect() because they do not have the proper
privilages to bind to a socket, by adding a struct proc * argument
to sobind() (and the *_usrreq() routines, and finally in{6}_pcbbind)
and do the sobind() with proc0 in nfs_connect.
OK markus@, blambert@.
"go ahead" deraadt@.
Fixes an issue reported by bernd@ (Tested by bernd@).
Fixes PR5135 too.
|

Also move the sampling into ether_input() where it can happen
at the interrupt and not within splnet() processing, which might
be less random. Discussed with mickey.
OK markus@, mcbride@

decent drivers prefer to have a lot of packets on the send queue so they
can queue a lot of them up on the tx ring and then post them all in one
big chunk. unfortunately our stack queues one packet onto the send queue
and then calls the start handler immediately.
this mitigates against that queue, send, queue, send behaviour by trying to
call the start routine only once per softnet. now its queue, queue, queue,
send.
this is the result of a lot of discussion with claudio@
tested by many.

before it is removed from the multicast group in_delmulti() will try to
access the no longer available ifp.
We invalidate the ifa_ifp back pointer in the ifa in if_detach() now and use
the ifa_ifp in in_delmulti() instead of the internal inm_ifp. By doing it
this way we know if the interface was removed.
This fixes a kernel panic triggered by ospfd and gif(4) tunnels.
looks good henning@ reyk@

which will be used for new interface routes. For example,
ifconfig em0 10.1.1.0 255.255.255.0 rtlabel RING_1
will set the new interface address and attach the route label RING_1 to
the corresponding route.

the randomness pool will be identical or predictably close anyways, and
nanotime() is expensive.

This provides a similar functionality as ARP balancing,
but also works for traffic that comes across routers.
IPv6 is supported as well.
The configuration scheme will change as soon we have sth better.
Also add support for changing the MAC address on carp(4)
interfaces. (code from mcbride)
