[PATCH 2/5] Give the kernel some time to up interfaces

[Philippe Seewer]

It does not really matter if the kernel needs some time or if
the ethernet handshake takes a while. It's a good idea to wait
a second after upping an interface to let things settle.

Hmm, shouldn't DHCP retries take care of this issue, and the server ARP
ping we've been talking about take care of it for static configs?

I would be a bit concerned that the backoff of dhclient may slow us down
more than a second, but I've not investigated if that is true.

I'm not really keen on adding a mandatory delay unless there is no other
option.

In the DHCP case, yes we could skip the sleep as dhclient will just
retry if the interface isn't ready. But for all other cases, we really
should give the hardware some time to initialize. 

During the years, I've had to use this for different cases, be it
slow firmware loading, weird drivers or just hardware that takes
longer. I've even had interfaces failing configuration if they didn't 
get some time to initialize. Another example: My e1000e card actually
takes just a bit more than 1 second to got to LOWER_UP when I do
modprobe e1000e && ip link set eth0 up

So this patch is just plain paranoia to make sure there's enough time
between upping the interface and trying to configure it. Yes, we could 
try to wait for LOWER_UP or something similar, but sleep 1 is simpler
and I haven't yet seen a case where that isn't enough and the slow down
is negligible.

As for other references: Stock isc 4.1 dhclient-scripts do it as well
for example. I admit, others doing it doesn't make it right. But it's 
just a pointer.

[PATCH 3/5] Be a bit more optimistic when setting mtus

[Philippe Seewer]

The usual approach to setting mtus is to set the interface down,
set the mtu then set the interface back up again. Modern hardware
and/or drivers may support setting this on the fly, so we try
this and fall back to the old behaviour it it doesn't work.

In addition this patch only allows mtus greater than 576, this is
taken from debian/ubuntu dhclient-script.

[PATCH 4/5] Add DAD do dhclient-script

[Philippe Seewer]

The manpage for dhclient-script says:

Before actually configuring the address, dhclient-script should
somehow ARP for it and exit with a nonzero status if it receives a
reply.

By using arping in dracut this is very easy, since arping has a
specific option to do just that.

Where's the addition of arping to 40network/install?

Also, this seems like it is screaming for a message -- it will confuse

Seems sane, some minor issues.

What's this all about? Does the test suite work?

*sigh* Yes. Apologies.

That is weird. The server startup code is the same as with the
NFS and NDB (except for 512MB allocated instead of 128MB).

The only thing I noticed, but that goes for all test-suites, is that if 
you don't have any local network connections the servers won't start 
producing exactly your error.

Do the other tests run with you?

Thanks,
Philippe

The BOOTIF bug fix could go as-is, but I think the rest of the series
needs to be respun once the issues are addressed.
