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.

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

cac1c6e392 Don't bother asserting: if we create the thread without KTHREAD_MPSAFE, 
it's not going to be MPSAFE.

9f725ef6cb * make interface a cloner

TODO: downing interface, unclone, and some tweaks for robustness

it a little less eager to panic.

62d92a1913 support compat ioctl's (OOOOOlalaSIOC stuff) 2010-11-07 19:47:18 +00:00

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).

cb4b70f7d6 Attach PF_LINK domain. ifconfig wants to play with it, plus there's 
no reason not to anyway.

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
* clarify the "can we still use the device's next pointer" calculation
  and move it to its own routine
* sprinkle dprintf

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

86d75f6695 truncate pcap output file 2010-08-13 11:45:47 +00:00
pooka
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
pooka
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.

36e63e6874 Make shmif memory access slightly more sane. Create a header which

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.

bcc65ff09f Split-off IPv4 re-assembly mechanism into a separate module. Abstract 
into ip_reass_init(), ip_reass_lookup(), etc (note: abstraction is not
yet complete).  No functional changes to the actual mechanism.
