It seems that RTNETLINK is now unconditionally enabled, I don't know
why.

It's required by newer RedHat and MDK initscripts, perhaps others.
ip, iproute and similar utilities use it, and so since it's commonly
required DaveM made it unconditional...  I think the checkin comment was
something along the lines of "make it unconditional unless Alan
complains about kernel bloat" :)

Hmm, perhaps RTNETLINK should be enabled
IFF networking is selected? I see to remember
that was the idea being bandied about...

Anyway, Merry Christmas to all -

But ifconfig and route don't use it, and now you can't do certain
things you could before.

One thing that comes to mind is showing the ipv6 routig cache,
because it only made that proc entry when it's not enabled.

Should I mention my kernel got bigger?

(I also was under the impression that this was a stable series.)

Basically because Dave refused to recognize lots of embedded setups don't
need the netlink crap and couldn't just accept defaulting it to Y we all
get lumbered with it

And I did complain. "Red Hat needs XYZ so we make it mandatory" is not an
appropriate approach to a problem.

[ Just got back from British Columbia... ]

No you did not complain.  I asked you specifically if it was ok, and
your response was that turning netlink/rtnetlink on by default was
fine with you.

It has zilch to do with redhat anything, in fact I had to ask vendors
first if they could still fit the kernel on their boot disks if I
added ~5K of object code to kernels with networking enabled.

It has everything to do with iproute2 and tcp_diag using it.

But not forcing it always on - thats not what I said.
