Linux 2.6.24-rc5 x86 architecture no longer Oopses...

I just got the following interesting behaviour. Never mind why the
original Oops (I was testing some experimental RPC patches), but there
appears to be a BUG_ON() triggered inside the dump() call.

Oops occurred with a build based on this afternoon's git tree from Linus
(v2.6.24-rc5-317-gfaa4877)...

Cheers

Yes - I don't know why the smp_processor_id() test has suddenly started
triggering in there.

I have a sledgehammer fix (below) which Ingo went all complicated about and
I assumed he had it in hand, but I can't see any patches anywhere?

I'd expect the kernel to spit that warning and then proceed with the usual
oops report - that's what it did in Miles Lane's case.  But it seems in
your case that the whole oops report simply vanished?

btw, I think we should track this as a regression, please.  It may not
strictly be a regression: the same problem might happen under 2.6.23,
although reports are only agaisnt 2.6.24-rc.

But things which impact our ability to get clean oops reports are critical
problems.

 commit c0a698b7443a9fce76b0a849f06c45ac78f3b0a0

    x86: fix die() to not be preemptible

    Andrew "Eagle Eye" Morton noticed that we use raw_local_save_flags()
    instead of raw_local_irq_save(flags) in die(). This allows the
    preemption of oopsing contexts - which is highly undesirable. It also
    causes CONFIG_DEBUG_PREEMPT to complain, as reported by Miles Lane.

No. I found what I assume is the remainder of the original a couple of

we are straight into an NMI which has hardirqs disabled.

it needs to be found out why the preempt_count suddenly went to zero. Is 
task struct corruption out of question?

Strictly we shouldn't care - we _know_ we've already hit a kernel bug and
who knows, perhaps that buggy code did an unbalanced preempt_disable().  So
make the oops code more robust.  

otoh, we don't want to be hiding a bug.  What piece of code guarantees that
we ender the oops code with preemption disabled?

raw_local_save_flags() doesn't disable interrupts?

argh. Indeed! (I wanted us to fix that misleading name eons ago, to 
*_save_flags_only(), but some stupid bikeshed painting discussion 
prevented it from ever happening.)

that should have been raw_local_irq_save(flags)!

but ... why is it done like that? Why do we first take the die.lock and 
disable interrupts afterwards? It's highly weird. 64-bit does it all 
correctly in traps_64.c, so unification will help us out - but so far 
perhaps the patch below we should do in 2.6.24?

local_read_flags().

So raw_local_save_flags() and raw_local_irq_save() have different semantics.

omigawd, what have we done?

Looks sane.

I suppose there's some reason why we can't just use spin_lock_irqsave(). 
But that reason was either so obvious or so unimportant that a comment was
not needed.  Sigh.

bug was introduced via:

  commit 39743c9ef717fd4f2b5583f010115c5f2482b8ae
  Author: Andi Kleen <ak@suse.de>
  Date:   Fri Oct 19 20:35:03 2007 +0200

      x86: use raw locks during oopses

-               spin_lock_irqsave(&die.lock, flags);
+               __raw_spin_lock(&die.lock);
+               raw_local_save_flags(flags);

that is not a correct open-coding of spin_lock_irqsave(): both the 
ordering is wrong (irqs should be disabled _first_), and the wrong 
flags-saving API was used.

so this is a post-2.6.23 regression and the fix is (now) obvious.

i really tried to get this fixed years ago - but did not think of 
local_read_flags as a solution. The patch below fixes this.

(if it's too burdensome to carry right now then i can regenerate this 
patch in 30 seconds in the 2.6.25 merge window - but please remind me 
then. Perhaps put in a patch into your queue that adds a comment to 
remind me :-) )

Subject: rename: local_save_flags => local_read_flags
From: Ingo Molnar <mingo@elte.hu>

The bug in commit c0a698b744 could have been avoided if
local_save_flags and local_irq_save wasnt so similarly
named. The syntax is similar as well.

rename all local_save_flags variants to local_read_flags,
as suggested by Andrew Morton.

I'd suggest that we add a local_read_flags() along with local_save_flags().
Then I can merge the parts of the patch which don't get destroyed by ongoing
churn and then we can come in and clean up the stragglers later.

ah, indeed.

like the patch below? (Only local_save_flags() should be used by drivers 
- but i stuck in the other variants as well for completeness.)

Subject: migration helpers for local_save_flags => local_read_flags rename
From: Ingo Molnar <mingo@elte.hu>

prepare for renaming of all local_save_flags variants to local_read_flags,
via migration helpers, as suggested by Andrew Morton.

Looks good.  We also have local_irq_save(), raw_local_irq_save() and
__raw_local_irq_save() which might or might not disable interrupts.  (Do we
really need three flavours of these?)

I guess that people's understanding of spin_lock_irqsave() (note the
irqsave versus irq_save inconsistency) is sufficiently good for nobody to
get tripped up by local_irq_save().  But it's a poor name nonetheless.


It'd be nice to move away from macros too if poss?

all disable interrupts. All the raw_ and __ APIs are for internal use 
only, they should _not_ be used by anything but directly lockdep related 
code.

yeah, but it's the historic name that stems from the old cli() API that 
had "global scope". I guess these days people know that irq-disabling is 
a CPU-local business, not a global thing? I cannot think of any good 
alternative name though.
