I’m not sure it should be atomic. It seems groups require their own
lock and this lock should be held while we perform if_addgroup() and
if_delgroup(). However if_creategroup() should set `ifg_refcnt’ to 1
and carp(4) should not touch groups internals.

Could you be more specific what broke?
I was going to revert at least half of that diff anyway because I
think it's just too ugly what we are doing here and I'm persuing a
different solution to the overall problem.

You are absolutely right. I was too optimistic.
Correct diff is below. It does not fix anything. Only advantage
is that carp does not access interface group internals.

I also think that atomic refcounting is not needed here. But it
does no harm as adding interface groups is not performance critical.
Question is if we want to use refcnt_... API even if it does more
than required. Or should we go with a self crafted ++ -- refcounting?
I think the API provides a nicer interface.

This would look like this, also fine with me. kasserts are also in

unwind(8): improve DNS64 detection
I noticed that sometimes DNS64 detection is not working correctly on
boot. Eventually I tracked it down to this:
Feb 6 08:56:22 x1 unwind[7139]: check_dns64_done: bad packet: too short: -1
The problem is that we are checking for dns64 while we might not yet
have a route to the nameserver provided by the router advertisement or
our IPv6 addresses are all tentative. Since we only re-schedule the
check when the network changes we are stuck. Instead we can check for
the presence of DNS64 when we know that DNS works, which is being
rescheduled correctly.
OK?
