we've parsed the config file. Makefile generation is too late if
we've introduce changes to the syntax of the metafiles to warn about
version skew, since we have to try to parse them and we get an parse
error that's rather baffling to the user rather than a 'your config is
too old, upgrade' which we should get.
We have to defer doing it until after we've read the user's config
file because we define machinename there. The version required to
compile the kernel is encoded in Makefile.machinename. There's no
real reason for this to be the case, but changing it now would
introduce some logistical issues that I'd rather avoid for the moment.
I intend to revisit this if we're still using config in FreeBSD 10.
This also means that we cannot introduce any config metafile changes
that result in a syntax error or other error for the user until 9.0 is

interfaces (such as when you are part of a carp pool), and you run
rpcbind -h to restrict which interfaces have rpc services, rpcbind can
none-the-less return addresses that aren't in the -h list. This patch
enforces the rule that when you specify -h on the command line, then
services returned from rpcbind must be to one of the addresses listed
in -h, or be a loopback address (since localhost is implicit when
running -h).
The root cause of this is the assumption in addrmerge that there can
be only one interface that matches a given network IP address. This
turns out not to be the case. To retain historical behavior, I didn't
try to fix the routine to prefer the address that the request came
into, since I didn't know the side effects that might cause in the
normal case. My quick analysis suggests that it wouldn't be a
problem, but since this code is tricky I opted for the more
conservative patch of only restricting the reply when -h is in effect.
Hence, this change will have no effect when you are running rpcbind
without -h.
