2.6.25-mm1: not looking good

2.6.25-mm1: not looking good

[Andrew Morton]

I repulled all the trees an hour or two ago, installed everything on an
8-way x86_64 box and:

security/selinux/netnode.c looks to be doing simple old kzalloc/kfree, so
I'd be suspecting slab.  But there are significant changes netnode.c in
git-selinux.

Interesting, that's the new major:minor code.  I'll go poke at it...

The duplicate filename <major>:<minor> messages are coming from
"sysfs-add-sys-dev-char-block-to-lookup-sysfs-path-by-major-minor.patch"
now in Greg's tree.  I'll take a look.

With git-selinux at top-of tree it's repeatably hanging in the CPA
self-tests (git-x86 stuff).  Last two lines are:

CPA self-test:
 4k 8704 large 4847 gb 0 x 0[0-0] miss 0

(clear as mud ;))

I will find the config knob to disable that test.  Of course, it could be
telling me that CPA is buggy.

For what it's worth I just looked over the changes in netnode.c and 
nothing is jumping out at me.  The changes ran fine for me when tested 
on the later 2.6.25-rcX kernels but I suppose that doesn't mean a whole 
lot.

I've got a 4-way x86_64 box but it needs to be installed (which means 
I'm not going to be able to do anything useful with it until tomorrow 
at the earliest).  I'll try it out and see if I can recreate the 
problem.

Perhaps it was tested only against slub?  That config uses slab.

Disabling CPA_DEBUG didn't help.  It's still hanging.  The final initcall
is init_kgdbts() and disabling KGDB prevents the hang.

Is this with the deprecated CONFIG_USB_DEVICE_CLASS=y? They have the
same dev_t as usb_device and would be a reason for the duplicates.

I dropped git-selinux and that crash seems to have gone away.  It took about
five minutes before, but would presumably have happened earlier if I'd
reduced the cache size.

btw, wouldn't this

be a bit clearer?  If it's correct - I didn't try too hard :)

In this case you do not have to disable kgdb, but just disable the
kgdb test suite.  Certainly I would be interested to know where it is
failing as it would indicate that there is a regression that is caused
by a change that occurred somewhere else in the kernel or a latent
defect in kgdb was triggered.  The kgdb test suite exercises a number
of kernel fault systems as well as arch specific single stepping when
it runs and when it fails it is likely worth it to track down which
test failed and why.

If you are looking to bypass the kgdb test suite you have two options.

The kernel option that runs the tests on boot (which is not on by
default) is CONFIG_KGDB_TESTS_ON_BOOT, and make sure this is off.

You can turn off the tests in an already compiled kernel that had the
testing turned on with boot by adding the boot argument with nothing
on the other side of the = sign of the kgdbts paramter.  Like:

kgdbts=


In terms of debugging what happened, if you have console output you
can save, please do send me the output of kernel boot with the kernel
boot argument:

kgdbts=V2

That enables verbose logging of exactly what is going on and will show
where wheels fall off the cart.  If the kernel is dying silently it
means the early exception code has completely failed in some way on
the kernel architecture that was selected, and of course the .config
is always useful in this case.

Thanks,
Jason.

do you have a stack-protector capable GCC? I guess not.

This is a catch-22. You do not have stack-protector. Should we make that 
a silent failure? or do you want to know that you don't have a security
feature you thought you had.... complaining seems to be the right thing to do imo.

A #warning sounds more appropriate.

Andrew, you don't seem to have slab debugging enabled:

# CONFIG_DEBUG_SLAB is not set

And quite frankly, the oops looks unlikely to be a slab bug but rather
a plain old slab corruption cause by the callers...

Yes, I'd agree.  All has been peachy since I dropped git-selinux.

that's the stackprotector self-test: you probably have a gcc that cannot 
build a proper stackprotector kernel. No damage other than having no 
stackprotector. Arjan Cc:-ed.

this warning is telling the user that the security feature that got 
enabled in the .config is completely, 100% not working due to using a
stack-protector-incapable GCC.

it's analogous as if there was a bug in gcc that made SELinux totally 
ineffective in some mitigate-exploit-damage scenarios. No harm done on a 
perfectly bug-free system - but once a bug happens that SELinux should 
have mitigated, the breakage becomes real. Having a prominent warning is 
the _minimum_.

having a build failure would be nice too because this is a build 
environment problem. (not a build warning - warnings can easily be 
missed because on a typical kernel build there's so many false positives 
that get emitted by various other warning mechanisms) Arjan?

hm, there's sel_netnode_free() in the stackframe - that's from 
security/selinux/netnode.c. Andrew, any recent changes in that area?

Keep in mind that slab might have been corrupted by someone else much 
earlier but we didn't notice due to the lack of CONFIG_SLAB_DEBUG.

I doubt if anyone will care much.

Not really.  In the selinux case we don't know that it'll break at compile
time.

Yeah, #error would work too.

incidentally, just today, in overnight testing i triggered a similar 
hang in the KGDB self-test:

  http://redhat.com/~mingo/misc/config-Thu_Apr_17_23_46_36_CEST_2008.bad

to get a similar tree to the one i tested, pick up sched-devel/latest 
from:

   http://people.redhat.com/mingo/sched-devel.git/README 

pick up that failing .config, do 'make oldconfig' and accept all the 
defaults to get a comparable kernel to mine. (kgdb is embedded in 
sched-devel.git.)

the hang was at:

[   12.504057] Calling initcall 0xffffffff80b800c1: init_kgdbts+0x0/0x1b()
[   12.511298] kgdb: Registered I/O driver kgdbts.
[   12.515062] kgdbts:RUN plant and detach test
[   12.520283] kgdbts:RUN sw breakpoint test
[   12.524651] kgdbts:RUN bad memory access test
[   12.529052] kgdbts:RUN singlestep breakpoint test

full log:

  http://redhat.com/~mingo/misc/log-Thu_Apr_17_23_46_36_CEST_2008.bad

note that this was a 64-bit config too - our tests do a perfect mix of 
50% 32-bit and 50% 64-bit kernels. So single-stepping of the kernel 
broke in some circumstances.

find the boot log below. (it also includes all command line parameters) 

This is the first time ever i saw the self-test in KGDB hanging, so it's 
some recent non-KGDB change that provoked it or made it more likely. The 
KGDB self-test runs very frequently in my bootup tests:

[   12.508236] kgdb: Registered I/O driver kgdbts.
[   12.511245] kgdbts:RUN plant and detach test
[   12.517418] kgdbts:RUN sw breakpoint test
[   12.521056] kgdbts:RUN bad memory access test
[   12.525515] kgdbts:RUN singlestep breakpoint test
[   12.531483] kgdbts:RUN hw breakpoint test
[   12.536142] kgdbts:RUN hw write breakpoint test
[   12.541007] kgdbts:RUN access write breakpoint test
[   12.546223] kgdbts:RUN do_fork for 100 breakpoints

so the latest kgdb-light tree literally survived thousands of such tests 
since it was changed last.

unfortunately, the condition was not reproducible - i booted it once 
more and then it came up just fine - using the same bzImage.

there's no recent change in x86.git related to the TF flag that i could 
think of to cause something like this. I checked changes to traps_64.c 
and entry_64.S, and nothing suspicious.

that came in via the UV-APIC patchset but the warning is entirely 
harmless. At that point we've got a single CPU running only so 
preemption of that code to another CPU is not possible.

native_smp_prepare_cpus() should probably just disable preemption, that 
way we could remove all those ugly preempt disable-enable calls from the 
called functions - per the patch below. (not boot tested yet - might 
provoke atomic-scheduling warnings if i forgot about some schedule point 
in this rather large codepath)

you noticed it ;-) Distro maintainers will notice it too if it pops up 
when something breaks StackProtector. Normal user might not notice. (but 
normal user might not notice a few hundred guest roots either)

but ... the real thing that made it slip into your config was that it 
was default-enabled in x86/latest - the patch below should fix that.

we need the warning: it could have caught the toplevel Makefile change 
last October that broke StackProtector completely. So no, we wont be and 
cannot be silent about this anymore - we need and now have an end-to-end 
test about it.

Try rmmod usb / insmod usb around suspend to see if it is
usb-specific, or if something went seriously wrong in core.

Or you might just bisect it ;-).

With the patch below, it seems 100% reproducible to me (7 out of 7
bootups hung).

The number of loops it could do before hanging were, in order: 697,
898, 237, 55, 45, 92, 59

It seems timing-related, so I'm guessing it could be some interaction
with interrupts?

BTW, I just tested a 32-bit config and it hung after 55 iterations as well.

I assume this was SMP?

While I had not tried it yet, my guess would have been this did not
happen on a UP kernel.  If it does occur on a UP kernel it means the
problem is squarely between the task scheduling after the exception is
handled and the kgdb state logic for re-entering the debug state after a
single step exception occurs.

It seems reasonable to go for 1000 iterations of this particular test to
declare success as pointed out by Ingo.  Previous versions of kgdb
handled some of the irq + single step + cpu sync slightly differently
and it is entirely possible there is a regression there.

Yes. But now that I realize this, I tried running same kernel with
qemu, using -smp 16, and it seems to be stuck here:

[   16.562659] kgdb: Registered I/O driver kgdbts.
[   16.565875] kgdbts:RUN plant and detach test

and the code is at kgdb_handle_exception():

        /*
         * Wait for the other CPUs to be notified and be waiting for us:
         */
        for_each_online_cpu(i) {
                while (!atomic_read(&cpu_in_kgdb[i]))
                        cpu_relax();
        }

Unless you have a qemu with the NMI patches, kgdb does not work on SMP
with qemu.  The very first test is going to fail because the IPI sent by
the kernel is not handled in qemu's hardware emulation.

Oops, no, and that makes sense.

I now picked up qemu 0.9.1 and applied the three NMI/SMI patches by Jan Kiszka.

So in qemu it seems to run fine now, except that I need to prod it
sometimes (it gets stuck in cpu_clock() and I have to break/continue
from gdb to make it proceed). Oh, there it made it to 1056, and gdb
can't interrupt anymore. Hmm. This is probably not a very good
testing/debugging environment if the qemu support is that bad. Sorry
:-)

But booting with nosmp on real hardware gets easily above 100,000
iterations of the loop (before I reboot), so it seems to be related to
that, anyway.

Yes, I believe it was testing it with slub.

Looks good to me, although before I fix this let me try and figure out 
why this code is causing the machine to puke all over itself.  
Priorities you know :)

There's no need to worry about them.  They merely indicate that the 
root hubs didn't resume along with everything else, because they were 
already suspended when the system went to sleep and so they were left 
suspended.  The return codes in usbcore will be changed soon so that 
this won't appear to be an error.

It gets stuck in kgdb_roundup_cpus(), verified by putting a printk()
before and after this call (in kgdb_handle_exception()). Simple, but
effective :-)

So I pulled your tree and I would agree there was a problem.  But it
seems unrelated to kgdb.  I bisected the tree because it worked starting
with the kgdb-light merge. 

It fails once with the patch below, but it is not clear as to why other
than the lock must have something to do with it.

I'll submit a patch to the kgdb test suite to increase the amount of
loops through the single step test as it is it can definitely catch
things :-)

2.6.25-mm1: Failing to probe IDE interface

[Mel Gorman]

[-- Attachment #1: Type: text/plain, Size: 742 bytes --]

An old T21 is failing to boot and the relevant message appears to be

[    1.929536] Probing IDE interface ide0...
[   36.939317] ide0: Wait for ready failed before probe !
[   37.502676] ide0: DISABLED, NO IRQ
[   37.506356] ide0: failed to initialize IDE interface

The owner of ide-mm-ide-add-struct-ide_io_ports-take-2.patch with the
"DISABLED, NO IRQ" message is cc'd. I've attached the config, full boot log
and lspci -v for the machine in question. I'll start reverting some of the
these patches to see if ide-mm-ide-add-struct-ide_io_ports-take-2.patch
is really the culprit.

ide-mm-ide-add-struct-ide_io_ports-take-2.patch is now in mainline so a
quicky confirmation would be to test Linus's tree.

Please try reverting ide-fix-hwif-s-initialization.patch first - it has
already been dropped from IDE tree because people were reporting problems
similar to the one encountered by you.

Thanks,

2.6.25 and latest git are both booting fine.

Thanks.

I reverted this patch and ide-mm-ide-make-ide_hwifs-static.patch (for compile
breakage reasons). It's better but still fails to find the IDE device.
What is better is that it finds ide0 at;

ide0 at 0x1f0-0x1f7,0x3f6 on irq 14

but does not identify any of the disks nor does it find ide1. For
comparison, a "good" dmesg looks like

Interestingly, bisection firmly blames this patch and QEMU boots with the two
patches reverted but fails with them applied so that patch does cause problems.
The failure on the laptop must be depending on some follow-on patch. I tried
a hatchet-job revert of the IDE patches between IDE-START and IDE-END in
the series file and it similarly fails to probe the IDE devices. So either
I made a mess of the reverts (strong possibility) or there is more than one
problem patch.

The third patch that needed reverting was
gregkh-pci-pci-clean-up-resource-alignment-management.patch (owners added
to cc). The relevant hint in the a diff between a broken and working bootlog was;

 system 00:09: ioport range 0x15e0-0x15ef has been reserved
+ PCI: bogus alignment of resource 7 [100:1ff] (flags 100) of 0000:00:02.0
+ PCI: bogus alignment of resource 8 [100:1ff] (flags 100) of 0000:00:02.0
+ PCI: bogus alignment of resource 9 [4000000:7ffffff] (flags 1200) of 0000:00:02.0
+ PCI: bogus alignment of resource 10 [4000000:7ffffff] (flags 200) of 0000:00:02.0
+ PCI: bogus alignment of resource 7 [100:1ff] (flags 100) of 0000:00:02.1
+ PCI: bogus alignment of resource 8 [100:1ff] (flags 100) of 0000:00:02.1
+ PCI: bogus alignment of resource 9 [4000000:7ffffff] (flags 1200) of 0000:00:02.1
+ PCI: bogus alignment of resource 10 [4000000:7ffffff] (flags 200) of 0000:00:02.1

With the resource alignment patch and the two IDE patches reverted, the
laptop is able to boot.

Thanks for tracking it down.

Hmm, it seems that the above patch was merged a week ago:

commit bda0c0afa7a694bb1459fd023515aca681e4d79a
Merge: 904e0ab... af40b48...
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Mon Apr 21 15:58:35 2008 -0700

    Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/pci-2.6
...
      PCI: clean up resource alignment management
...

but it could be that the issue has been already fixed in git tree
(could you verify it please?).

BTW according to lspci output you should be able to use piix driver
instead of ide_generic on this laptop.

Thanks,
Bart

Latest git boots on the laptop so somewhere along the line, it got fixed.

I know but the config is a bit minimal for faster building as it's only
intended for sniff-testing patches.

Thanks for the help.
