2.6.17-rc5-mm1

[Andrew Morton]

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/irqtrace-support-nonx86.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:

there is nothing wrong with calling local_bh_disable() in irqs-off

so remove this over-eager WARN_ON().

hmm ... do you have the NMI watchdog enabled? Could you try with

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?

I have nmi_watchdog=1.  I'll reboot with 0 and see if it'll trigger.

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.

ok, great. The patch below turns off NMI on i386 automatically.

-------------------
Subject: lock validator: disable NMI watchdog if CONFIG_LOCKDEP, i386

The NMI watchdog uses spinlocks (notifier chains, etc.),
so it's not lockdep-safe at the moment.

and NMI disabling wasnt perfect on x86_64 either. (we did it too late, 
which allowed a few NMI ticks to still occur.)

---------------

this does the NMI-watchdog disabling at the right place on x86_64.

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 :)

All is well.  Back to nmi_watchdog=1, no warning, no lock.

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.

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.

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)

Re: 2.6.17-rc5-mm1

[Roland Dreier]

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...

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?

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:

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

sorry - the messages are indeed cryptic, partly because there are lots 
of illegal state transitions and the printout is atomated, and partly to 
keep the already sizable lockdep printouts as compact as possible.

What happened here is that a lock (-type) that had the {in-hardirq-W} 
state bit set, and lockdep observed an event that also sets the 
{hardirq-on-W} state bit: illegal.

here is a rough translation of the usage history state bits:

 {in-hardirq-W}: lock was exclusively acquired in hardirq context
 {in-hardirq-R}: lock was read-acquired in hardirq context
 {in-softirq-W}: lock was exclusively acquired in softirq context
 {in-softirq-R}: lock was read-acquired in softirq context
 {hardirq-on-W}: lock was held exclusively with hardirqs enabled
 {hardirq-on-R}: lock was read-held with hardirqs enabled
 {softirq-on-W}: lock was held exclusively with softirqs enabled
 {softirq-on-R}: lock was read-held with softirqs enabled

to interpret the lock state at a glance, there's an even shorter 
representation of the state bits:

 (&base->lock#2){++..}
                 ^^^^

'+' : irq-safe [lock was taken in irq context]
'-' : irq-unsafe [lock was taken with irqs enabled]
'.' : unknown [lock has not yet become irq-safe or irq-unsafe]

'?' : read-locked with both hardirq context and with irqs enabled

the first character is for exclusive-locking in hardirqs, the second for 
exclusive-locking in softirqs, the third is for read-locking in 
hardirqs, the fourth is for read-locking in softirqs.

this means that the "{++..}" sequence shows that this lock is 
hardirq-safe and softirq-safe, and was never read-locked. [the later one 
is not surprising from a spinlock - but lockdep doesnt know that it's a 
spinlock, it deals with all lock types in a unified way]

(more details about the usage history state bits are in 
Documentation/lockdep-design.txt and in include/linux/lockdep.h)

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

Yes, that builds fine.

However the kernel won't boot for me... it oopses early on in
save_stack_trace().  I'm attaching a bootlog, plus another try booting
with nmi_watchdog=0, plus my config.

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.

do you have KALLSYMS_ALL enabled? This looks like a thing we already
fixed as well... but it also looks a bit odd ..

[combo patch] lock validator -V2

[Ingo Molnar]

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)

Re: 2.6.17-rc5-mm1

[Roland Dreier]

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.

hmmm skb_dequeue is called in a hard irq...

.. yet it was taken only with spin_lock_bh() in unix_stream_connect,
leaving interrupts enabled (and thus not allowing use inside 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.

[Patch -rc5-mm1] Lockdep annotate rpc_populate for child-relationship of its mutex

rpc_populate is creating a child inode in a directory, and the
parent already has it's mutex locked. Similar to the VFS code
this needs I_MUTEX_CHILD nesting annotation

I can't boot with that patch. I even don't see "Uncompressing

I have 2.6.17-rc5-mm1 +

BTW. I got error when compiling kernel/latency.c, so I change

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:

which forces CONFIG_PROFILE_LIKELY off if LATENCY_TRACE is enabled.

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

The possibly-relevant patches are:

box:/usr/src/25> grep msi series 
gregkh-pci-pci-msi-abstractions-and-support-for-altix.patch
gregkh-pci-pci-altix-msi-support.patch
allow-msi-to-work-on-kexec-kernel.patch
pci-disable-msi-mode-in-pci_disable_device.patch
x86_64-msi-apic-build-fix.patch

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.

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)

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.

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

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.

What's the standard way to teach lockdep about this?

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().

I can't reproduce this bug with current

http://redhat.com/~mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm1.patch

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

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 <mingo@elte.hu>

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)

Randy, do you have an MSI-X device perhaps? Could you try the patch 
below?

	Ingo

------------------------------------------------------
Subject: genirq MSI fixes
From: Ingo Molnar <mingo@elte.hu>


This is a fixed up and cleaned up replacement for genirq-msi-fixes.patch,
which should solve the i386 4KSTACKS problem.  I also added Ben's idea of
pushing the __do_IRQ() check into generic_handle_irq().

I booted this with MSI enabled, but i only have MSI devices, not MSI-X
devices.  I'd still expect MSI-X to work now.

irqchip migration helper: call __do_IRQ() if a descriptor is attached to an
irqtype-style controller.  This also fixes MSI-X IRQ handling on i386 and
x86_64.

Jan, this stack trace looks wrong.  We have no information which tells us
how we entered the pagefault handler.  Userspace hasn't started up yet, so
we probably entered the fault handler from the kernel.  But that info has
been lost.

I agree that the trace is incomplete, but I'm not certain (without seeing at least twice as much of the raw stack) whether the unwinder is to blame here. After all, looking at the registers, the stack was already overflowed at the point the (nested) exception was taken, so there is no way to know whether the stack contents can actually be relied upon.
