4d5d6d9aa5 Add a new AF/PF_ROUTE which is 64-bit clean which makes the routing socket 
interface (and its associated sysctls) act identically for both 32 and 64 bit
programs.  The old unclean one remains for backward compatibility.

a05de63f6b Ensure that a) loopback attaches after all the domains have attached 
b) loopback is configured only after it has attached.

9a17e75e0e Autoconfigure 127.0.0.1 for lo0. 
(testing bind/connect/etc. is now possible on a virgin rump kernel
without the need to ifconfig anything)

7ed2407316 Actually, unlike e.g. carp, bridge can be its own component since 
it doesn't want to join the protosw party.  We can deal with other
linkhappy stuff with weak symbols.

(where is our modular networking stack?)

9b108f4af3 Support bridging. As usual, it would be nice if this could be a 
separate component, but King Ifdef doesn't let us.

e7ec49d29a sockin cannot be loaded the same time as rumpnet_inet because both 
provide a PF_INET domain.  Guess that real inet is more useful and
don't put sockin on the "all components" list.

fdb9b6e9bf Revert previous: it introduces a dependency between sockin and the 
netinet rump components and will have to be done another way.

it's not going to be MPSAFE.

a500a55cf2 Make virtif a cloner so that it can be brough to life also with 
"ifconfig create".  As previously, virt<n> interfaces with the
host's /dev/tap<n> (I guess it could be made explicit with
"ifconfig media", but leave it this way for now).

942c727880 Prefault bus pages in driver attachment. This seems to work around 
weird corruption I've been seeing (most likely a host kernel bug).

c2fbfedc83 Fix hopefully last off-by-one: if we fill the bus, we must also 
advance the "first" pointer.  This problem triggered only if the
bus was filled in the first round, since the first pointer is at
the end-of-bus only for the bootstrap round.

86ea9bb1a9 * fix off-by-wrap case where current datagram aligns exactly with 
the end of the bus

  and move it to its own routine

9ae53a340e Take kernel lock before passing data to if_input. This is in line 
with IPL_NET interrupts generally not being MPSAFE.

b97bdf9424 Include a timestamp in the frame header. When converting to pcap, 
it can give some idea of when packets were sent.

nb. it's the sending host's timestamp, not an observer timestamp
like in the typical pcap case.
 2010-08-13 10:13:44 +00:00

ce68b7ae71 Include a pointer to the beginning of the buffer and add support 
to the packet dumper.  This helps in situations where the juicy
details are in a bus multiple generations old.

855ec3e9a1 Change bus header a little: reserve only 32bits for the lock and 
use 32bit atomic ops to handle it.  Begin data from 0x10 instead
of 0x14.

6fe4bb4ba8 Support carp. It would be nice to support this as its own component, 
but there's about 1000 lines of #ifdef which disagree with my wish.
