ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc5/2.6.17-rc5-mm1/
- The git-cfq tree is causing oopses and has been dropped.
- New reiser4 code drop.
- Merged the generic-IRQ handling code.
- Merged the runtime locking validator. If you enable this your machine
will run slowly.
- The build is broken on ia64 and probably on everything apart from x86,
x86_64 and powerpc. Check out the hot-fixes directory, as it won't be
broken for long.
- Dropped the git-viro-bid-* git trees - they're getting many rejects
against other things in -mm.
- Merged the new readahead code.
- Merged the generic statistics infrastructure patches.

if you disable CONFIG_DEBUG_LOCKDEP it should be quite OK. (If debugging
is disabled then the lockless "chain cache" is fully utilized and we
should rarely go into the more complex portions of kernel/lockdep.c.)

with the following patches i just sent:
patches/genirq-ia64-build-fix.patch
patches/irqtrace-support-nonx86.patch
patches/lockdep-rwsem-fix.patch
ia64 defconfig builds fine now. I'd expect other non-x86 architectures
to build fine too (with the lock validator disabled).

ok, that WARN_ON is over-eager. Fix is below:

Subject: lock validator: remove softirq.c WARN_ON
From: Ingo Molnar <[email protected]>
there is nothing wrong with calling local_bh_disable() in irqs-off
section (as long as the local_bh_enable isnt done with irqs-off),
so remove this over-eager WARN_ON().

i'd still love to figure out what's going on here.
hmm ... do you have the NMI watchdog enabled? Could you try with
nmi_watchdog=0?

hummm. NTFS does really really weird things with mutexes...
can you try to enable the mutex debugging config option to see if that
triggers anything?

this one could be related to NMI. We are already disabling NMI on
x86_64, but i thought i had it fixed up for i386 - apparently not.

Booted with nmi_watchdog=0, no warning and no deadlock. It produced
fruit for NFTS.

This ops is a unique object assigned to a different "id" string.
The first snd_seq_device_register_driver() called from emu10k1_synth.c
is the registration for the id "snd-synth-emu10k1".
Then in init_device(), the corresponding devices are initialized, and
one callback registers again another device for OSS sequencer with a
different id "snd-seq-oss" via snd_seq_device_new() inside the lock.
Now it hits the lock-detector but the lock should belong to a
different ops object in practice.
This nested lock may happen only in two drivers, emu10k1-synth and
opl3, and only together with OSS emulation. Since the OSS emulation
layer don't do active registration from itself, no deadlock should
happen (in theory -- I may oversee something :)

ok fair enough
Jiri, can you test the patch below? (I don't have this hardware)
The ops structure has complex locking rules, where not all ops are
equal, some are subordinate on others for some complex sound cards. This
requires for lockdep checking that each individual reg_mutex is
considered in separation for its locking rules.

Indeed.
But it still looks as something very strange.
There are some GFP_KERNEL allocations on the way to this function.

ok so selinux_complete_init() does
spin_lock(&sb_security_lock);
next_sb:
if (!list_empty(&superblock_security_head)) {
struct superblock_security_struct *sbsec =
list_entry(superblock_security_head.next,
struct superblock_security_struct,
list);
struct super_block *sb = sbsec->sb;
spin_lock(&sb_lock);
sb->s_count++;
spin_unlock(&sb_lock);
spin_unlock(&sb_security_lock);
nesting sb_lock inside sb_security_lock
while
put_super() takes the sb_lock, then calls __put_super() which calls
selinux_sb_free_security which calls superblock_free_security() which takes sb_security_lock
which means the nesting is opposite.

hhmmm curious.. you don't happen to have nmi watchdog enabled??

That's totally unsafe even without lockdep and should be fixed
instead. I guess someone bungled the notifier chain conversion.
The NMI notifiers need to be lockless.

hm. Do you have the NMI watchdog enabled? [does /proc/interrupts show
any increasing NMI counts?]

That's the second report of del_timer-in-hardirq being a bug.
Unfortunately I'm unable to decrypt the local validator's output. Perhaps
when Arjan and Ingo do the analysis of these reports they could provide a
little guidance into what the traces are actually telling us, so that
others can learn to use them?

weird. We are holding base->lock#2 [CPU#1's timer base lock], _and_ we
execute restore_nocheck - which is a return-to-userspace thing.
unfortunately the stacktrace provides no clues of how we got here.
For such nasty cases i have a kernel tracing patch prepared, you can get
it from:
http://redhat.com/~mingo/lockdep-patches/latency-tracing-lockdep.patch
just apply it ontop of your current tree and accept all the new .config
options as the kernel suggests them to you. Then rebuild and reboot into
the kernel, and reproduce the lockdep bug. Once such a bug is reported,
/proc/latency_trace should have a full kernel trace leading up to the
bug. Please upload that trace to your site and send us the URL.
(the tracer runs nonstop and it saves the current trace if it encounters
a lockdep bug. That way i can see the history of the bug.)
if possible it would be nice to boot with maxcpus=1 as well, to make
sure we have all relevant kernel activity traced. (assuming that booting
with maxcpus=1 does not make the bug go away)

Building 2.6.17-rc5-mm1, I get this:
net/built-in.o: In function `ip_rt_init':
(.init.text+0xb04): undefined reference to `__you_cannot_kmalloc_that_much'
This seems to be coming from:
rt_hash_locks = kmalloc(sizeof(spinlock_t) * RT_HASH_LOCK_SZ, GFP_KERNEL);
I have CONFIG_NR_CPUS=32, so RT_HASH_LOCK_SZ ends up as 2048. Also, I
have both CONFIG_DEBUG_SPINLOCK=y and CONFIG_PROVE_SPIN_LOCKING=y so
spinlock_t is bloated up quite big:
typedef struct {
raw_spinlock_t raw_lock;
#if defined(CONFIG_PREEMPT) && defined(CONFIG_SMP)
unsigned int break_lock;
#endif
#ifdef CONFIG_DEBUG_SPINLOCK
unsigned int magic, owner_cpu;
void *owner;
#endif
#ifdef CONFIG_PROVE_SPIN_LOCKING
struct lockdep_map dep_map;
#endif
} spinlock_t;
I only have 8 CPUs in the box, so updating my config from the x86_64
defconfig fixes things for me.
No patch because I don't really know how to fix this properly...

yeah, totally agreed, they need to be raw notifiers. Havent had time to
investigate it in detail yet - i went for the easier hack of disabling
NMIs while lockdep is enabled.
Here's the kernel trace of it happening on x86_64:
<...>-417 0D... 2983us : __lockdep_acquire (ffffffff81a5cb18 0 0)
<...>-417 0D... 2983us : __lockdep_acquire (0 0 0)

<...>-417 0D.h. 2987us : notifier_call_chain (atomic_notifier_call_chain)
<...>-417 0D... 2988us : trace_hardirqs_off (trace_hardirqs_off_thunk)
<...>-417 0D... 2989us : __lockdep_acquire (1 1 0)
<...>-417 0D... 2989us : mark_lock (__lockdep_acquire)
<...>-417 0D... 2989us : mark_lock (__lockdep_acquire)
<...>-417 0D... 2989us+: mark_lock (__lockdep_acquire)
<...>-417 0D... 2991us : check_chain_key (__lockdep_acquire)
<...>-417 0.... 2992us : _raw_spin_lock (_spin_lock)
<...>-417 0.... 2992us : _spin_lock (dput)
that shouldnt be an atomic_notifier but a raw_notifier.

Confused. NMI uses notify_die(), which doesn't take locks?
We'll probably accidentally take locks when actually reporting an NMI
watchdog timeout, but that doesn't seem terribly important.

and it was in selinux_complete_init
for some reason the #0 is not being printed here (it normally is), which
would give a simliar backtrace. In this case it was ok,
selinux_complete_init was the sole guilty party.

but here it gets interesting; this is the function that triggered the
final deadlock message (well we knew that already from the first line of
the message), which gets called from

which gets called from

... but wait we know this one already from where I put [*], so we're now
done. put_super takes sb_lock, then calls __put_super which calls
selinux_sb_free_security which takes sb_security lock.

well we also now know that it came from a sys_umount; that might help
chasing stuff down if it's more fuzzy than this example

hm ... atomic_notifier_call_chain ought to be fine - it uses
rcu_read_lock(), which uses preempt_disable(), which is NMI-safe.
so i think this NMI problem might be lockdep-specific. I think it might
be the NMI iret that confuses lockdep. (and irqflags-trace in
particular)

That phrase could use some rewording IMO. It sounds more like a question
than a statement.

could you try the patch below and set NR_CPUS back to 32?

Subject: lock validator: fix RT_HASH_LOCK_SZ
From: Ingo Molnar <[email protected]>
on lockdep we have a quite big spinlock_t, so keep the size down.

there's some bad interaction between the new dwarf2 unwind info
stackframe walker code in mm1 and lockdep's stacktrace code on x86_64.
I'm investigating this currently, meanwhile you can try the quick hack
below.

i've uploaded lock validator -V2, a rollup of all current fixes (against
-rc5-mm1) to:
http://redhat.com/~mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm1.patch
(Andrew got all these fixes as individual patches already)
Ingo
I'm seeing problems with MSI-X interrupts on 2.6.17-rc5-mm1. I'll try
to debug the MSI patches in -mm further in the next day or so, but for
now I'll post the symptoms.
When I load the ib_mthca driver with MSI-X interrupts enabled, I get
the following crash as soon as the first interrupt is generated.

yet hpsb_bus_reset() calls skb_dequeue (indirectly, via the inlined
abort_requests() function) in a hard irq.

On x86_64, I'm seeing what may be flakiness related to skb_dequeue. I
haven't had a chance to look too closely, but the serial excerpt I have is
below. The real BUG of interest is near the end with
BUG: sleeping function called from invalid context at include/linux/rwsem.h:49
At the time of failure, a kernel compile was taking place. I've also seen
one ppc machine (not ppc64) lock up. There was no output to console so it
may or may not be related.

rpc_populate is creating a child inode in a directory, and the

I can't boot with that patch. I even don't see "Uncompressing
Linux..." - machine reboots.
I have 2.6.17-rc5-mm1 +
genirq-cleanup-remove-irq_descp-fix.patch
lock-validator-irqtrace-support-non-x86-architectures.patch
lock-validator-special-locking-sb-s_umount-2-fix.patch
from hot fixes
+
Arjan's net/ipv4/igmp.c patch.
BTW. I got error when compiling kernel/latency.c, so I change
if (DEBUG_WARN_ON((val < PREEMPT_MASK) && !(preempt_count() & PREEMPT_MASK))))
to
if (DEBUG_WARN_ON((val < PREEMPT_MASK) && !(preempt_count() & PREEMPT_MASK)))

could you try to 1) disable PREEMPT, 2) apply the -V2 rollup of all
fixes so far to 2.6.17-rc5-mm1:
http://redhat.com/~mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm1.patch
? I'll try your config meanwhile.

PREEMPT wasnt the problem but CONFIG_DEBUG_STACKOVERFLOW (at least).
There's some other debug option that seems incompatible too - i'm still
trying to figure out which one.

i've also uploaded an updated tracing patch to:
http://redhat.com/~mingo/lockdep-patches/latency-tracing-lockdep.patch
which forces CONFIG_PROFILE_LIKELY off if LATENCY_TRACE is enabled.

do_IRQ() did a jump-to-zero. So there's no handler installed.

But this bug seems to be at a higher level - I'd be more suspecting the
genirq patches forgot to install a handler somehow.

yep. No desc->irq_handler. That should be 'impossible' on x86_64,
because the irq_desc[] array is initialized with handle_bad_irq, and
from that point on x86_64 only uses set_irq_chip_and_handler(), which at
most can set it to another (non-NULL) handle_irq function. Weird.
does MSI much with the irq_desc[] separately perhaps, clearing
handle_irq in the process perhaps?

aha - drivers/pci/msi.c sets msix_irq_type, which has no handle_irq
entry. This needs to be converted to irqchips.

still ... that doesnt explain how the irq_desc[].irq_handler got NULL.

It has it's own irq_desc array
static struct msi_desc* msi_desc[NR_IRQS] = { [0 ... NR_IRQS-1] = NULL };
Too tired right now. I look into this tomorrow.

Arjan's sound patch is wrong: the key must not be in a dynamic variable!
Could you try the patch below? This uses the ID string as the key. (the
ID string seems to be based on static kernel strings most of the time,
so this might as well work)

ah ...
then i guess a quick solution would be to do:
if (!irq_desc[irq].irq_handler)
__do_IRQ(irq, regs);
else
generic_handle_irq(irq, regs);
in arch/x86_64/kernel/irq.c [and in arch/i386/kernel/irq.c], and
__do_IRQ() should handle the old-style irq-type MSI code just fine.

The only way to fix drivers/pci/msi.c is to delete it.
Honest, there is nothing salvageable in that code. I've been looking at
the issues involved in supporting MSIs on various powerpc platforms and
I came to the conclusion that there isn't a single re-useable line of
code in there. Not only it's totally specific to a given set of intel
chipsets, but it's also broken beyond imagination. I wonder how that
code got in there in the first place, especially maskqueraded as
"generic" code. Greg must have been drunk.
At this point, the only solution for us (powerpc) is to allow the arch
to have it's own implementatin of the toplevel MSI API (pci_enable_msi()
etc...). From there, depending on what we come up with, we'll look into
moving that back into generic code, but we are under some pressure for
time (stupid 2 weeks merge window thing is a pain sometimes).

Indeed (fixing ".irq_handler" to be ".handle_irq"), with that change
MSI-X works fine with ib_mthca on my system. The only slightly funny
quirk is that the IRQ type is shown as "PCI-MSI-X-<NULL>", I guess
because it's printing handle_irq_name(NULL).
However (as BenH pointed out) there's definitely some work to do to
untangle MSI...

No, not drunk, just that no other arch offered up any potential help to
get this working. So, we have one arch that has it working well, and
finally, many years later when PPC64 catches up with the rest of the
world, we have issues :)
Feel free to help untangle it. ia64 just did a big chunk of work on
this, and there are further patches in the -mm tree that help get it
working there. ppc64 and other arch support are also welcome. You are
the ones who know how your arch handles this stuff the best.

2 week merge window? Come on, just give it to me and let it sit in -mm
for a while. I have some stuff in there for over 2 months before it
goes to Linus to make sure that it's safe. You can do the same for your
trees.
I gladly accept patches...

Without having looked at it very hard, I'd venture that this is a false
positive - that driver uses disable_irq() to prevent reentry onto that
lock.
It does that because it knows it's about to spend a long time talking with
the mii registers and it doesn't want to do that with interrupts disabled.

Where? Since 2.6.17-rc1 the notify_die() callback uses RCU, not
spinlocks.

correct.

i still consider it a 'quirky' locking construct, because disabling
interrupts for a long time also disables all other devices sharing the
same IRQ line - not nice.
Also, this is a really hard case for lockdep to detect automatically.
(fortunately it's also relatively rare)
OTOH, the straightforward lockdep workaround would be to take the
spinlock and thus disable all local interrupts - not too nice either.
Albeit in some ways it's still a bit nicer conceptually than disabling
the irq line, because other CPUs are still operational, and under
certain locking designs [preempt-rt] spin_lock_irq() does not disable
local interrupts.
Steve, can you think of any better solution? I dont have this card.

the scsi controller who shares that irq with your NIC just *enjoys* long
disable_irq() periods.. it can be nice and lazy about it ;)

the tracer fix for PROFILE_LIKELY is below. I have also uploaded an
updated tracing patch to
http://redhat.com/~mingo/lockdep-patches/latency-tracing-lockdep.patch
which allows the enabling of PROFILE_LIKELY && LATENCY_TRACING again.
There's an updated combo patch too:
http://redhat.com/~mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm1.patch
for easy pickup of all current fixes against mm1 baseline.

Until this popped up, I didn't know I had this card either ;)
(the last time we dealt with this card was to help someone else)
Anyway, I'll look into the way this card works and start to play with it
when I get some time.
Andrew, do you have any docs that I can read to understand the card a
little better?
Thanks,

Not yet. One possibility would be to use existing locks and to get rid
of the disable_irq(). One technique could be to disable the IRQ on the
card (i think the code already does this), and then call
synchronize_irq() instead of disable_irq().

appears while starting avahi daemon.

thanks - these traces made it really easy to spot the problem! The
problem seems to be caused by a pagefault:
<...>-1 0D..1 10648us : check_chain_key (__lockdep_acquire)
<...>-1 0D..1 10649us+: _raw_spin_lock (_spin_lock_irqsave)
<...>-1 0D..1 10651us : do_page_fault (error_code)
<...>-1 0D..1 10652us : trace_hardirqs_off (ret_from_exception)
<...>-1 0D..1 10653us : trace_hardirqs_on (restore_nocheck)
<...>-1 0D..1 10654us : mark_held_locks (trace_hardirqs_on)
<...>-1 0D..1 10654us : mark_lock (mark_held_locks)
<...>-1 0D..1 10655us : save_trace (mark_lock)
<...>-1 0D..1 10656us : save_stack_trace (save_trace)
<...>-1 0D..1 10658us : print_usage_bug (mark_lock)
i think what happened is that the pagefault happened with irqs disabled,
and the entry.S return-to-exception-site irq-flags tracing code
mistakenly turned on the irq flag - causing the mismatch and lockdep's
confusion.
if it's easy to reproduce it once more, could you apply the patch below?
That will add a trace entry about what address faulted and at what EIP.
Please also upload vmlinux.bz2 because the EIP will be a raw hex number
and i'll have to look it up. (or if it's too big then please disassemble
vmlinux via objdump -d vmlinux and upload a ~100 lines portion that is
mentioned in the new trace entry next to the do_page_fault trace entry
near the end of the latency_trace output)

please use the updated patch below - it adds more info so that we can

whether it was userspace or kernelspace.

Yes, looks that way, although oddly I don't see this warning myself upon
performing a umount (w/ 2.6.17-rc5-mm1-lockdep). Patch below should
fix.

great! Here's the cleaned up fix for Andrew:
----------------------------
Subject: lock validator: irqflags-trace entry.S fix
From: Ingo Molnar <[email protected]>
this fixes the irqflags-tracing bug reported (and relentlessly
debugged) by Michal Piotrowski: if we took a fault while interrupts
were disabled (for example of a vmalloc area) then irqflags-tracing
mistakenly assumed that the iret would re-enable interrupts.

There's nothing odd about a panic in that kernel.

OK, I think Martin said something about the machine going down early
inside the CPU scheduler.
Are you able to work out what file-n-line move_tasks+0xf1/0x2a8 is at?
gdb vmlinux
(gdb) l *0xffffffff801244b4
Or, if CONFIG_DEBUG_INFO wasn't set:
- Enable CONFIG_DEBUG_INFO
- make vmlinux
- gdb vmlinux
(gdb) p move_tasks
(gdb) l *(0x<address of move_tasks> + 0xf1)
