Andre,
I've recently noticed a regression between RELENG_5 and CURRENT.
In CURRENT ng_ksocket is unable to work as divert socket. Since
you have touched divert code recently I'm asking you. Today I'm
going to dig deeply there, but probably you can give some ideas
without investigation.
A test for this functionality looks like this:
/usr/sbin/ngctl -f- <<-SEQ
mkpeer echo dummy dummy
name .:dummy echo_div
mkpeer echo_div: ksocket echo inet/raw/divert
name echo_div:echo div_sock
rmhook dummy
msg div_sock: bind inet/0.0.0.0:8888
SEQ
ipfw add 1000 divert 8888 all from any to any via fxp0
And packets should flow thru fxp0 in both directions. Do not
try lo0, there are some problems in there.
You also need this patch (going to commit it soon), if you are
running INVARIANTS:
