multiprocessor kernel problem

multiprocessor kernel problem

[Roger Crandell]

I have 2.4.0  test 10 and test 11 installed on a multiprocessor (Intel)
machine.  I have tried both test versions of the kernel.  I configured
the kernel for single
and multi processor.  When I boot single processor, iptables will run
fine.  When I boot the machine with the multiprocessor kernel and run
iptables, the kernel dumps several pages of hex and the final two lines
of output are:

Killing interrupt handler
scheduling in interrupt

The kernel logs nothing and you must reset the machine to bring it back
up.  I believe this is a kernel issue rather than an iptables
issue.

Does anyone have experience with iptables on a multiprocessor machine?

I am not currently subscribed to this list, so may I please be
personally CC'ed with the
answers/comments posted to the list?  I have also submitted this to the
netfilter list of which I am
a member.

Look through the "several pages of hex" for any number in square +
angle brackets i.e. [<xxxxxxxx>] (particularly the EIP and the stack),
and write these down.  Then run these numbers through ksymoops.

i tried it about a month back with -test11.  my quad ppro simply
locked up and died when i issued "iptables -nL".  i got no logs just a
freeze.  perhaps only my keyboard mouse and NIC died and the rest of
the machine kept on running.  i posted a couple of times to the
netfilter mailing list but got zero response.

My development box (running test10pre5) is SMP, and it works fine.  I
haven't updated to the latest kernel version because I like my
filesystems in one piece, and the netfilter code hasn't changed.

What is your kernel configuration, and iptables version?  Have you
patched the kernel?

Thanks for the report,
Rusty.

yes, but is it a dual machine or is it an N-way SMP with N > 2?  the
other guy with iptables/SMP problems also has a quad box.  could this
perhaps be a problem only when you have more than two processors?

i tried 2.4.0-test10 (no patches) with iptables 1.1.2.  this is an alr
revolution quad6 (4 ppros).

i posted this to the netfilter mailing list a while back.

Yes, hacked my machine to think it had 4 cpus, and boom.

There are two problems:
(1) initialization of multiple tables was wrong, and
(2) iterating through tables should not use cpu_number_map (doesn't
    matter on X86 though).

Please try attached patch.

Thanks,
Rusty,

Rusty,

Excellent!  I applied the patch and netfilter is happy with 4 processors.  Thank you and
thanks to everyone else who sent suggestions.

ok i'll give this a whirl .... success!

netfilter/iptables seems to be up and working on my quad ppro box
now.  i am running your "quick guide to firewalling" from the howto
until i get my rules straightened out.

thank you very much.

Rusty,

I have two identical machines and the problem exists on both.  The machines
have Megaplex II quad  Pentium III Xeon PCI ISA system boards.  I have 550
Pentium III Xeon, 100/512 processors.  I am running test11 which I
downloaded a few days ago.  I have installed no patches.  My iptables is
1.1.2.

I compiled two version of the kernel, one is single processor and one is
SMP.  I can successfully run iptables on the single processor kernel and I
can also get it to work with two processors using the SMP kernel.  With 4
processors the system boots fine, but when I try to run iptables with 4
processors the system freezes solid.  It does not write anything to the
system log.

We currently have iptables working on a single processor machine in our
network.  It typically tracks an average of 13000 connections with peaks
reaching 21000 connections.  It works flawlessly.  We want to upgrade from
10/100 interfaces to GigE.  We hoped to use the 4 processor machines to do
this.

I am attaching my kernel config file.  If you have any ideas how to get all
four processors working please let me know.


Thanks


Roger

multiprocessor kernel problem

[Roger Crandell]

I should have mentioned this is a 4 processor machine with a 64 bit
buss.

perhaps the netfilter stuff isn't 4-way SMP safe.  my quad ppro box
seizes with iptables too.  however, many people report it working with
2-way SMP boxen.

has anyone gotten netfilter/iptables to work on a SMP box with more
than 2 processors?

i recall old 2.0.x kernels deadlocking on a 4-way
until x=35 or so.  maybe this is somehow similar.
