ifstated(8) missing if state changes?
Hi list,
it seems that ifstated(8) sometimes does not see all events and thus
fails to change state.
My setup consists of 2 boxes with 5 carp interfaces. CARP works fine, on
box frw1 all are MASTER and on box frw2 all are in BACKUP state.
When i bring down all carp interfaces on frw1, all get MASTER on frw2.
However, ifstated(8) on frw2 does not change state.
[EMAIL PROTECTED] [~] # cat /etc/ifstated.conf
init-state auto
carp_up = carp0.link.up carp1.link.up carp2.link.up
carp3.link.up carp5.link.up
carp_down = carp0.link.down || carp1.link.down || carp2.link.down ||
carp3.link.down || carp5.link.down
state auto{
if ($carp_up) set-state master
if ($carp_down) set-state slave
}
state master{
init{
run logger CARP up!
# run /root/scripts/carp-up.sh
}
if ($carp_down) set-state slave
}
state slave{
init{
run logger CARP down!
# run /root/scripts/carp-down.sh
}
if ($carp_up) set-state master
}
I did a ktrace on the ifstated(8) process on frw2 and the dump gives:

The first 3 lines show the transition from BACKUP to MASTER. carp3 and
carp 5 are missing!
The other lines show the transition from MASTER to BACKUP. I have
verified in both cases that *all* carp devices changed state with
ifconfig(8).
Are there known issues with ifstated(8) or kevent(2) about lost events?
As a workaround i will change my $carp_up definition to test if *any* of
the interfaces is up, but that isnot a good solution.
Any clues?
