This looks like another network-namespace regression.
icmp_send() does:

        net = rt->u.dst.dev->nd_net;

The bridge netfilter code attaches a fake dst_entry to the
skb which has dev == NULL when passing it to IPv4 netfilter.

Pavel, do you have a better ideas for fixing this than
instantiating a dst_entry in br_netfilter.c for every
device (or at least for every namespace)?

Ingo, you have that patch in your tree, are you going to push that to

The problem still persists and I have no clue at all what's the root
cause. The symptom is a stuck local apic timer interrupt as we have
seen it on those AMD X2 systems with C1E enabled. This box does not
advertise C1E, but the behaviour is the same.

Christian, it would be great if you could bisect the git tree so we
get an idea which patch is exposing this problem. My feeling is that
the problem itself is there with 2.6.24 as well but not
exposed. That's just a gut feeling and I could be wrong as usual.

Thanks,

Hm, "git whatchanged net/ipv4/inet_timewait_sock.c" returns

The description of the problem was not entirely correct, the
bridge-netfilter dst_entry does have a proper device pointer,
it points to a dummy net_device structure however that doesn't
have a namespace associated with it. This blows up in
__ip_route_output_key.

For now I suggest this fix. Andy, could you please test whether it
fixes the problem?

[BRIDGE]: Fix crash in __ip_route_output_key with bridge netfilter

The bridge netfilter code attaches a fake dst_entry with a pointer to a
fake net_device structure to skbs it passes up to IPv4 netfilter. This
leads to crashes when the skb is passed to __ip_route_output_key when
dereferencing the namespace pointer.

Since bridging can currently only operate in the init_net namespace,
the easiest fix for now is to initialize the nd_net pointer of the
fake net_device struct to &init_net.

Should fix bugzilla 10323: http://bugzilla.kernel.org/show_bug.cgi?id=10323

Soeren said it no longer happens to him in http://lkml.org/lkml/2008/4/9/53
but unfortunately it still happens with me using -rc9. So I kidnapped his 
bugzilla report :-)

In the bugzilla entry I said earlier today that "hpet=disable" apparently
makes the problem go away (42 boots OK so far, whereas without this
boot option it hangs ~90% using vga=6 and ~10% using vga=0x0364)

I tried to bisect it, but sometimes in pre 2.6.25-rc1 kernels it takes
30 boots before the first hang to occur. So bisection is not reliable...

If someone proposes a patch I will be glad to test it!

PS: The similar bug in buzilla 10377 also appears to be "fixed"
by using hpet=disable, see comment #17 in that bug.

Ok! The biggest problem however is: I can only run bisects on weekends. :-(
And even then: it takes up to 2 hours until the timer gets stuck... and the 
system freezes...
But, on the other hand... does ANYBODY know a way how I can see if the 
apictimer drifts/(getting slower and slower)?

Yes. Still being investigated (mostly by private mails).
Change that caused the regression after -rc5 has been located (see bugzilla),
but the real cause appears to be deeper.

I have reproduced the issue on kernel 2.6.22.17, so it looks like it's
not a kernel regression, but an X server issue.

Well, it does not drift. It's stopped by some magic, but I do not
understand why we do not see that behaviour in 2.6.24. The code logic
in this area is really unchanged.

Can you disable CPUIDLE for a test please ?

I'm guessing it will.  I've been testing my older kernels today and
somehow I'm unable to reproduce the original problem, so I need to
figure out what is different about my config now and before.

it appears that this is a much older regression, from april 2007.

So this is a regression, but not from 2.6.24 (although somehow
it never hit me before). I don't know about the policy of closing
regressions that come from way before the previous kernel version, 
if there is any. Then I will let you manage the bugzilla #10117
as you see fit (but I will be "there" to hopefuly test any 
proposed patches).

I dropped the bug from the list of recent regressions, so it doesn't block
bug #9832 any more.  However, this still is a bug and regression, so the
bugzilla entry remains open.

Soerens original report was a 2.6.25 regression.

And #10377 that was closed as a duplicate of #10117 was also reported as 
a 2.6.25 regression.

#10117 seems to suffer from the common disease of people hijacking an 
existing bug, but Soeren's issue that was what was originally tracked in 
#10117 is (or was) a 2.6.25 regression.

If other people have similar problems that already existed in 2.6.24 
these are different issues that should be tracked in their own bugs.

Well, I'm really not 100% sure it was a regression from 2.6.24 and I'm not
sure bug #10377 should have been marked as a duplicate.

I made bug #10117 block bug #9832 again, but it would be nice to sort this out.

Why do we think that the cause of bugs #10117 and #10377 is the same?

Both of them probabilistically hang early in the boot.
On both !CPUIDLE and hpet=disable seems to be working around the
problem.
Both are Core 2 Duo based with 64 bit kernel.

One difference I saw was that #10377 fails on battery. That may be
because when on battery CPUs may be running at lower freq during boot
and that is probably helping this problem in terms of timing.

Soeren said in [1] "note that I've never seen these hangs on 2.6.24*".

FWIW, this macbook pro1,1 has only a core 1 duo, so x86 == 32bit...

So I think we should leave bug #10117 to track the original issue (hangs on
MacBook Pro1.1 w/ Intel Core Duo x86-32), reopen bug #10377 and use that
to track the Core 2 Duo 64-bit issues.

Any objections to that?

Sorry. When I said Core 2, I was referring to Carlos and his updates on
#10117.

Sorry, I meant that this could be something general and not a amd64

This bug tracks Soerens problem.

And the fact that Carlos and Mark discuss their different problems in 
the same bug is just plain wrong.

We must learn to more aggressively point people at reporting their 
issues in own bugs, instead of hijacking an already existing similar
looking bug (that might be for a different issue).

Carlos, Mark, can you open own bugs for your issues?

Last I heard from Soeren, this was not reproducable on 32 bit any more.
All recent updates on #10117 from Carlos is on Core-2 Duo 64 bit. If the
problem is still reproducable on 32 bit then probably having 2 bugzillas
to track is fine with me.

No objections on that, but I already took the liberty of doing exactly 
this...

Soeren has confirmed this.

His bug (that was a 2.6.25 regression) seems to be fixed, and the bug is 
therefore closed.

#10117 seems to have comments about reported by at least 3 people other 
than Soeren, and unless you are 100% sure these are for the same issue 
each of them deserves an own bug.

Although it might sound like bureaucratic overkill having separate bugs 
even for reports that might be for the same issue prevents situations 
like we just had in #10117.

Ok, sorry then. I know something odd happened with bug #10117 as
you so aggressively pointed out. 

In my defense I must say that I was about to report the hang with
"ACPI: Processor [CPU1] (supports 8 throttling states)" to lkml 
when I read Soeren's post in this list.
Then I did _not_ send the "me too" email and kept on following
what was going on.

So when I read that Soeren's bug was closed I wrote in the
bugzilla that I was still seeing the same issue, and that
I wanted to reopen it. I should not have done that and it
won't happen again.

> And the fact that Carlos and Mark discuss their different problems in 
> the same bug is just plain wrong.

You are saying it is a different problem, but it may be the same.
Sometimes I had to reboot 30+ times before the hang could happen!
And the last messages were _exactly_ the same.

But let's not argue about that, I just wanted to help by pointing
out that maybe the bug was being closed too early. In trying to
help I just caused more confusion, for which I appologize.

I understand now, but you made me feel bad about it.

Sorry for my wording, it was not meant personally.

It's a general problem in bug trackers that one person reports one 
issue, and other people say "I have the same bug" and start discussing 
their problem, which might or might not turn out to be the same.

And the result was e.g. here that Venki marked #10377 as a duplicate of 
#10117 saying "Both are Core 2 Duo based with 64 bit kernel." although 
this is not true for the bug #10117 was originally created for.

... which you should realize that this is generally a _GOOD_ thing. This 
whole Linux thing is about doing things in a group, not about doing 
things separately. It permeates everything and it's our main strength.

Analogously to nuclear fission and to torrent streams, bug handling 
needs a "critical mass" as well - the more testers, the better. (even if 
they end up having different issues)

So i'd rather see bugs being mistakenly handled together (they are easy 
to separate out once they are established to be separate) than the same 
bug being processed on two different tracks.

Your rigid, buerocratic view of this matter is wrong, harmful and it 
actively discourages testers. Please stop it.
