2.6.17-rc5-mm2

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc5/2.6.17-rc5-mm2/


- A cfq bug was fixed in mainline, so the git-cfq tree has been restored.

- Various lock-validator and genirq fixes have been added.  Should be
  slightly less oopsy than 2.6.17-rc5-mm1.

- I just realised that I've been accidentally not updating the PCI tree for
  a while.  Will be restored in next -mm.

- Has been booted and has passed various stress-tests on quad x86_64,
  quad ancient-Xeon, quad power4, quad ia64, dual old-PIII and a modern
  pentium-M laptop.  So if it breaks, it's your fault.




Boilerplate:

- See the `hot-fixes' directory for any important updates to this patchset.

- To fetch an -mm tree using git, use (for example)

  git fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git v2.6.16-rc2-mm1

- -mm kernel commit activity can be reviewed by subscribing to the
  mm-commits mailing list.

        echo "subscribe mm-commits" | mail majordomo@vger.kernel.org

- If you hit a bug in -mm and it is not obvious which patch caused it, it is
  most valuable if you can perform a bisection search to identify which patch
  introduced the bug.  Instructions for this process are at

        http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt

  But beware that this process takes some time (around ten rebuilds and
  reboots), so consider reporting the bug first and if we cannot immediately
  identify the faulty patch, then perform the bisection search.

- When reporting bugs, please try to Cc: the relevant maintainer and mailing
  list on any email.

I put the fix for slab corruption into mm1, and it did indeed cure that.
However, if I add git-cfq.patch, my box still explodes.

Andrew, you probably want to leave out git-cfq for a few days as it'll
throw rejects once Linus pulls the for-2.6.17 cfq urgent fixes. I'll
fixup the branch and the apparently silly bug that crept in that branch
and give you a ping about when to reenable it!

OK, thanks.  I put a revert patch into the hot-fixes directory.

I assume you're using the ahci driver here.

And we did a jump-to-zero.  I'm suspecting the sata changes.

Is this the mysterious missing ->mode_filter, perhaps?  I don't think so -
we test for null there.

Should ahci.c have a data_xfer vector?  Right now it's left at NULL.

And here we collapsed instead of generating a backtrace.  Both Ingo and the
x86_64 guys have been playing with the backtrace code.

A .config would be useful too.

hm, i cannot reproduce the stack backtrace secondary crash with your

ah, managed to reproduce it!

Jan, the dwarf2 unwinder apparently fails if we call a NULL function. 
The patch below will provoke it artificially on any box (as long as you 
have an IDE system). I've attached the incorrect backtrace attempt 
below, and the expected backtrace further below.

the relevant config options are:

CONFIG_DEBUG_INFO=y
CONFIG_FRAME_POINTER=y
CONFIG_UNWIND_INFO=y
CONFIG_STACK_UNWIND=y

Seems that a fix got lost.  Please add this:


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.

That is expected behavior, as a NULL program counter (to the unwinder) means end-of-stack-frames. It can't do anything
in that case, so the only solution I see is to either
- not at all call the unwinder from trap.c if the instruction pointer before the first unwind is not within kernel
space, or
- force fall-through to the old logic if the first unwind attempt didn't yield a change to either rIP or rSP (implying
that in that case there was no unwind information found to start with).

What do you think?

Is it actually _expected_ that we'll encounter a NULL EIP during the unwind?

Because if it is not, then this is a good indication that the unwind
attempt hasn't worked, so we should fall back to some other approach if we
encounter a NULL at _any_ point in the backtrace, not the start.

Creating too much information is waaaaaaaaaaay better than creating too
little.  (This is a case in point - we're trying to fix a bug here and the
unwinder is preventing that).

In fact, if there's any means at all by which we can detect that something
has gone wrong with the unwind we should fall back.

Let me just agree with myself here.  It would be wildly unacceptable for
the unwinder to cause us to get _less_ information than we presently do
under any circumstances, please.  That would be a really bad impediment to
kernel development.

The problem is that the unwind is expected to end with an odd state (i.e. fail), at least until all possible root
points of execution (i.e. bottoms of call stacks) have a proper annotation forcing their parent program counter to zero
(which I don't expect to happen soon, if ever, because I think this is something difficult to prove). Thus the only
reasonable thing to do is to check whether the first level of unwinding failed.

This might be a config or boot option (and might be forced on for a short while), but I generally don't think this is
helpful, given that the entire point of the added logic is to remove (useless) information (even more that if you have
to rely on the screen alone, you have to live with its limited size, and pushing out an old-style stack trace after the
unwound one would likely make part or all of it as well as the register information disappear).

firstly, i'd suggest to use another magic value for 'bottom of call 
stacks' - it is way too common to jump or call a NULL pointer. Something 
like 0xfedcba9876543210 would be better.

for the RIP/EIP to get corrupted is a common occurance. So is stack 
corruption. So the fallback mechanism shouldnt be a 'short while' 
side-thought, it must be part of the design.

If we use a much better magic value to delimit the stack then our 
confidence that the stacktrace is correct will be much higher.

In all other cases (if we go outside of the stack page(s)) we _must_ 
fall back to the dump 'scan the stack pages for interesting entries' 
method, to get the information out! "Uh oh the unwind info somehow got 
corrupted, sorry" is not enough to debug a kernel bug.

What we _can_ ignore are stack/register corruptions that accidentally 
cause a valid unwind call chain to be printed. That is impossible to 
detect and it's much less likely than say normal stack or register 
corruption. But we _must not_ ignore clear parsing errors. This is a 
really basic thing ...

Also, it might be worth doing a two-pass thing.  Pass 1 doesn't print
anything - it just figures out whether pass2 will succeed.  If not, fall
back without printing anything.

correct, that's what stacktrace.c does for example. In the first lockdep 
queue i switched show_trace() to make use of stacktrace.c, so it can be 
used for printing traces too.

Are there other heuristics we can apply?  For example, we have a pretty
good idea whereabouts the top of a kernel stack is.  If we don't end up
close to that offset then we can assume that something went wrong?

Plus a config or boot option is too late.

That's contrary to common use (outside of the kernel). I'm opposed to this. Detecting an initial bad EIP isn't a
problem, and the old code can be used easily in that case.

RIP/EIP corruption, as said above, can be easily handled. RSP/ESP corruption, as I understand it, isn't being handled
in the old code, and so I can't see what improvements the new code could do here (given that instruction and stack
pointers serve as the anchors for kicking off an unwind).

Again, you miss the point that the very last unwind operation must always be expected to move the stack pointer outside
the stack boundaries, which would mean triggering the fallback path in all cases. With this, we could as well leave out
the entire unwind code and keep everyone of us manually do the separation of good and bad entries in the trace shown.

but 0 is pretty much the worst choice for something that needs to be 
reliable - it's the most common type of machine word in existence, 
amongst all the 18446744073709551616 possibilities. And we need not care 
about userspace's prior choices, this code and data is totally under the 
kernel's control.

i'm not only talking about RSP/ESP corruption, but about stack 
corruption. I.e. some area of the stack is corrupted. With the scanning 
method we at least get some other entries out - while with the unwind 
method we only say 'sorry'.

anyway, i think that handling a bad initial RIP/EIP would be a good 
first step and it should solve the problem at hand. (it will also serve 
as a basis for whatever other heuristics we might want to apply later 
on)

no, i dont miss that point at all. What _you_ are missing is the obvious 
solution: stacks on x86_64 are already linked to each other, via 
fixed-position pointers at the end of the stackpages. So the unwinder 
can easily check whether the 'next stack' as suggested by the link at 
the end of the page is indeed the same as the unwind jumpout does. If 
not => fallback.

same for i386 - there too the stacks are linked via non-unwind data. The 
unwinder can do a pretty good verification of the jumpout.

I've missed some context here, but assuming you're talking about DWARF
and reliably marking the end of the backtrace, why not actually mark
stack termination instead of futzing around with zeros?  GDB now
detects the return address column in the unwind info being set to
undefined and treats that as an end of stack.  Then you can treat any
other zeros you encounter as problems.

Definitely not.

If it needs one, something is _very very_ wrong.

Unlike traditional IDE interface (which most SATA uses), ahci and
sata_sil24 do PIO over DMA, and that is hooked at a much higher level
(->qc_issue).

I would be very interested in a trackback with symbol info...

Chris, this won't compile with CONFIG_MODULES=n.

If module unloading is unsafe (why?) then a suitable workaround would be to
take an additional ref on the module (__module_get()) so that it cannot be
unloaded.

This bug is still present in 2.6.17-mm1, and even worse it's now in 
Linus' tree.

Hello,

here are small link issues on s390.

I think the early_init_irq_lock_type() undef is related to the
lock-validator patch. Shall I just :

too easy ... the lock-validator should be ported to s390 I guess. What are
the steps to follow ?

As for the `__iowrite64_copy', shall we :

#define writeq(b,addr) (*(volatile unsigned long *) __io_virt(addr) = (b))
#define __raw_writeq writeq

For the moment, it boots but I'd like to make sure i'm in the right
direction before sending patches. However, the following one is safe and
fixes a very small compil issue on s390 in klibc.

Can't comment on the port issues yet but we plan to add the s390 support
to the lock-validator. It is just a cool debugging tool.

Seems reasonable. __io_wirt() is a nop, so you are simply writing to the
specified address.

Patches that fix compile problems are always fine with me. If it turns
out wrong for some obscure reason we can fix it up later.

OK. So I'll keep my #ifdef hack for the moment.

This patch adds __raw_writeq required by __iowrite64_copy.

It also adds all the related quad routines.

This looks wrong: "b" is a u64 and you write it to something that is an
unsigned long. We're going to miss a few bits on 31 bit platforms...

Indeed. Here's another version protecting the quad macros with __s390x__.
to be applied on rc6-mm1.

For the moment, __raw_writeq() is needed by __iowrite64_copy() which is
protected by CONFIG_64BIT. Some drivers also use it.

Thanks for reviewing,

C.

Please use an unsigned long long cast and get rid of the ifdefs...

hpsb_register_highlevel() does
	        write_lock(&hl_irqs_lock);
which is not irq safe
yet

[PATCH 2.6.17-rc5-mm3] ieee1394: hl_irqs_lock is taken in hardware interrupt context

[Stefan Richter]

ohci1394 and pcilynx call highlevel_host_reset from their hardware
interrupt handler (via hpsb_selfid_complete).  Therefore all readers and
writers of hl_irqs_lock have to disable interrupts.  Reported by Jiri
Slaby and J. A. Magallon.

s/fixes it/makes it go away/

Please describe these patches better.

Where was the outermost lock taken?  How do we know that an attempt cannot
be made to take them in the opposite order?

For some reason the lockdep code expected that hardirqs would be enabled.

> http://www.stardust.webpages.pl/files/mm/2.6.17-rc5-mm2/bug_2.jpg

So it's claiming that we're taking multiple i_mutexes.

I can't immediately see where we took the outermost i_mutex there.  Nor is
it immediately obvious why this is considered to be deadlockable?

(lockdep tells us that a mutex was taken at "mutex_lock+0x8/0xa", which is
fairly useless.  We need to report who the caller of mutex_lock() was).

inlining caused one level to be removed from the backtrace
one level is in fs_remove_file, the sub level is usbfs_unlink (called
from fs_remove_file)

>   Nor is

what is missing is that we tell lockdep that there is a parent-child
relationship between those two i_mutexes, so that it knows that 1)
they're separate and 2) that the lock take order is parent->child

yeah this has been bugging me as well; either via a wrapper around
mutex_lock or via the gcc option to backwalk the stack (but that only
works with frame pointers enabled.. sigh)

OK.

I'll duck this patch for now, pending a tested-n-changelogged one, please.

Actually, __builtin_return_address(0) works OK with -fomit-frame-pointer,
and that's all we need here.

yes - but that means we'd have to propagate the EIP through all the 
mutex calls (and the assembly functions, etc.). I tried it and it's 
really a nightmare. What we can do is to have better information if 
FRAME_POINTERS is enabled.

Yes, I managed to lose a fix-up-the-rejects patch.  I wonder why it

Please send `grep SCSI .config'.

I'd be guessing that either SCSI_SRP needs to depend upon SCSI_TGT or we
need a stub function for scsi_tgt_queue_command(), for when SCSI_TGT
is undefined.

Looking at the Kconfig help text, it looks to me like SCSI_SRP without
SCSI_TGT makes no sense. I guess at some point I must have been
thinking "I have no idea what SCSI RDMA Protocol is, so I'll build it
as a module just to be safe" -- I somehow missed the word "target" in
its Kconfig help text when I enabled it...

Re: 2.6.17-rc5-mm2

[Barry K. Nathan]

Ok, the kernel that I now have booting is 2.6.17-rc5-mm2 + my
pata_pdc2027x patch + the 3 hotfixes that I saw when I started trying
to build the kernel (i.e. without git-scsi-target-fixup but with the
other 3 that are now present).

During boot of my Debian sarge system, this kernel always gives this
warning at "Starting MTA:"
http://static.flickr.com/47/158326090_35d0129147_b_d.jpg

Then, a minute or two after boot, it usually (well over 50% of the
time, but not quite 100%) gives this oops:
http://static.flickr.com/51/158326091_6a7057834c_b_d.jpg

If it doesn't fail with that oops, it usually tends to fail with other
oopses (I have not managed to capture any of those, but they all seem
to mention network-related stuff). Once, it just froze up without an
oops. The oops I posted happens often enough that it's probably
unjustifiably difficult to try reproducing the other oopses until this
one is fixed or worked around.

I plan to try 2.6.17-rc5-mm1 + mingo's latest lockdep patch for that
kernel + a properly fixed-up pata_pdc2027x, to see whether that kernel
fails the same way; I've built it but I won't have a chance to test it
for another 3-6 hours.

That's the mysterious lockdep warning - I'm not sure we've got to the
bottom of that.

Damn, sorry.  LLC is completely borked.  You should emphatically set
CONFIG_LLC=n.

Barry, if the system boots up fine with LLC disabled (and if you still 
get the lockdep warning), then please apply the following patch:

  http://redhat.com/~mingo/lockdep-patches/latency-tracing-lockdep.patch

accept all the default 'make oldconfig' options and reboot into the 
patched kernel. If everything goes well then the system should still 
boot up fine, you should still get the lockdep warning - but this time 
there should be a long trace in /proc/latency_trace. Please upload that 
trace - it gives us the kernel's function trace, leading up to the 
warning.

Just one problem with that...

config ATALK
        tristate "Appletalk protocol support"
        select LLC

This box runs netatalk for both file and print service, but I could
temporarily disable it for testing... Ok, the kernel's up and running
w/o CONFIG_LLC and CONFIG_ATALK now, and the warning still happened at
boot time, but it has stayed up for over an hour without keeling over
with a panic.

It looks like netatalk was fixed at some point so that it can do AFP
over TCP without the presence of a running atalkd, so unless I buy a
really old used Mac, I shouldn't need CONFIG_ATALK for the file server
anymore. Also, to make a *long* story short, I also should be able to
get rid of the print server in a few weeks. I'll still need to
occasionally boot back into a CONFIG_ATALK kernel to use the print
server until then, but I should be able to run an ATALK-less kernel
for days at a time (i.e. when the print server is not in use)...

ok. I forgot to mention that it's probably a good idea to first apply 
my lockdep-combo patch to -mm2:

  http://redhat.com/~mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm2.patch

this includes all current -mm hotfixes and all lockdep fixes. (The 
lockdep tracer patch will still apply cleanly ontop of the combo patch.)

Actually, I noticed that the tracer patch applied with fewer offsets
(i.e. "more cleanly," in a sense) with the lockdep-combo patch applied
first, so I did that.

I'm doing building the kernel, but I haven't been able to boot it yet:
This system boots the kernel off floppy disks, and under
2.6.17-rc5-mm2, the floppy drive no longer works! The disk spins but
the kernel can't read any of the disk's sectors, even for other
known-working floppies. I'll have to boot back into 2.6.17-rc4-mm3
before I can copy the new kernel onto a disk and boot from it. That
will take me a couple of minutes, although I have to go to school in
under an hour so I might not get to it until later today.

Oh, wait, let me try a sadistic experiment first: Let's see if I can
format a floppy disk with the floppy drive in this non-functioning
state... no, "/dev/fd0: Read-only file system", 100% reproducible.

does it get any better if you remove:

I won't be able to check until later today. With the tracing patch
added (for figuring out the warning at boot time), my kernel is about
50-60K too large to fit on a 1.6MB floppy. I first need to see if I
can trim or modularize some fat from my kernel without affecting the
reproducibility of these bugs... (If all else fails, I'll probably add
a CD-RW drive to this box and boot kernels from that.)

just disable FORCED_INLINING in the .config, turn on EMBEDDED and select 
OPTIMIZE_FOR_SIZE, and that should give you 30-40% of kernel size 
savings.

also, the latest combo patch:

  http://redhat.com/~mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm2.patch

should have the floppy bug(s) fixed.

I was already doing OPTIMIZE_FOR_SIZE. I didn't think of disabling
FORCED_INLINING, thanks for reminding me of that. I managed to trim
the kernel in other ways.

I'll try that later today (and I'll also provide the
/proc/latency_trace to help figure out the warning). In the meantime,
I can confirm that the floppy drive started working again with
lock-validator-floppyc-irq-release-fix.patch reverted.

BTW, the latency_trace is close to 130K. Should I send it to you by
private mail instead of to the list? Or should I compress it and send
it as an attachment?

Andrew, I can also confirm that the LLC hotfix is allowing LLC (and
AppleTalk) to work again.

Hmm... disabling FORCED_INLINING didn't make much if any difference.

Yes, the latest combo patch works. It still gives the warning, too
(copied here since it looks slightly different with the latency trace
patch added):

I've posted the /proc/latency_trace here:

It turns out that I was *way* off on the size in my last mail. It's

ok, thanks - this pinpointed the problem. I have just sent the fix for 
that (against -mm3), does your networking card still work with that 
patch applied, and if yes, is the lock validator silent on your box now? 

Btw., the easiest way to find out whether there's a lockdep problem on 
your box is to grep for debug_locks in /proc/lockdep_stats - it should 
still be on 1. If there's a warning, it goes to 0. That is an easy to 
script flag.

heh ;) Yeah. But it does tell us everything (and much more) about the 
immediate history of any particular bug.

bzip -9 has a better than 1:20 compression ratio on latency traces, so 
the 130K should go down to ~6K - perfectly fine for attaching it. (that 
way others on lkml can take a look too)

Strange. ATALK doesn't need 802.2LLC, merely SNAP.

There's CONFIG_LLC, and there's also CONFIG_LLC2. I wonder if actual
802.2LLC support is the latter, not the former...

Is it supposed to work on x86_64?

I've tried enabling something minimal (full config attached):

CONFIG_PROVE_SPIN_LOCKING=y
# CONFIG_PROVE_RW_LOCKING is not set
# CONFIG_PROVE_MUTEX_LOCKING is not set
# CONFIG_PROVE_RWSEM_LOCKING is not set

CONFIG_FRAME_POINTER=y
# CONFIG_UNWIND_INFO is not set
CONFIG_FORCED_INLINING=y

---

and I get unexpected failures in the validator self test, and then a
kernel panic. Something like this:

[test output]

yeah, it's supposed to work.

please send me the real full config you used for the build - this one 
has only the =y entries. (from which it's hard to reproduce your 
original config)

when running it through 'make oldconfig' and grepping for =y it didnt 
match your original config, but the resulting kernel was just as broken 
as yours, so it's good enough for now ;-) Below is the crashlog over 
serial.

Anyway, full config attached.

It's a .17-rc5-mm2 + 2 hot-fixes:
	lock-validator-x86_64-irqflags-trace-entrys-fix.patch
	revert-git-cfq.patch

thanks. Your config triggered 4 different bugs! 1 nasty slab.c one and 3 
locking-selftest bugs.

please try my latest lockdep-combo patch:

  http://redhat.com/~mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm2.patch

ontop of vanilla -mm2. The combo patch includes all current -mm2 
hotfixes plus all current lockdep fixes.

It gives me an Oops: "NULL pointer dereference at
kmem_cache_alloc+0x23/0x7b" and than a panic (attemp to kill idle task).

I'll try to get a nice picture...

ok, this was yet another slab.c early init assumption ...

could try the latest combo patch at:

  http://redhat.com/~mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm2.patch

does this one finally boot for you?

I've applied the single patch. At first I've got problems (lots of
messages scrolling on the screen, and then a kernel panic). They are
related to netconsole because disabling it lets me boot :)

If the problem with netconsole doesn't go away I'll set up a serial
console to capture the enormous output.

This reliably goes kablam on an x86_64 machine with a tg3 network card 
which was also happening for 2.6.17-rc5-mm1. A patch bisect found that 
reversing git-net.patch and git-net-git-klibc-fixup.patch on top of 
the -mm3 got rid of the problem. Don't ask me why.

The console log I have of the most common oops is below and the .config 
used is attached. The oops happens reliably but at varying times and not 
always the same oops either. Usually sshing into the machine and compiling 
the kernel is enough. On at least one occasion, sshing to the machine 
triggered it.
