Not really, it just shows the nvidia driver being buggy and using a
sleeping gfp allocation mask when it should not.

Hi, Bradley Chapman wrote:

> So what exactly is the problem?

I'm seeing
- User Interface corruption under X. That shows as random processes
crashing with SIGFPE (interestingly, often two unrelated X processes crash
at the same time -- sometimes one of them is the server) or SEGV, 

I just switched to -test11 and turned off preemption. I don't see any more
crashes or weird behavior, but now performance sucks -- console scrolling
(frame buffer) stalls for seconds, keyboard repeat likewise, and the X
server suddenly decides it wants twice the CPU (60% instead of 30%).

I'll rebuild test11 with preempt and check whether there are any changes.
(Yes I know, changing two variables at the same time was somewhat stupid.)

If you're careful enough, nothing bad or good will ever happen to you.

Hi,

I know it's binary only, but the NVidia driver produces the folowing

Hi,

I know it's binary only, but the NVidia driver produces the following

If it seems relevant I can supply more info ...

Just a caution, I suspect that this is related to something happening in
a small time window, and identical configs might not work the same on
different machines. Interrupt timing can be changed by disk layout,
rotational speed of the drive, interrupt priority, maybe even a user
event like keystroke or mouse action.

Comparing configs will help, but may not be consistent.

Maybe brute force is the best way to deal with this nasty one ? I'm thinking: 
It must be rather easy to make a tool that takes a .config file and an 
argument "This kernel seems in trouble Yes / No". If an option is enabled, 
and this kernel config crashes, you increase the likelihood of that option 
(i.e. you increment a counter). If an option is enabled, and this kernel 
doesn't crash. you decrement a counter. In the end, you'll end with 
statistics about which kernel option is likely to cause problems.

SORRY. Please, inore this report. It IS 100% reproducable - if you load
wrong (compiled without debugging) modules... Maybe you should only accept
bug-reports either without modules or with CONFIG_MODVERSIONS...

Really sorry for taking your time.

Here's my 2.4 patch, which was actually against the suse kernel so you
might get fuzz/rejects for Config.in and the drivers/char/Makefile

It's fairly simple, just put the slab sizes you want into the sizes
array in crasher.c

2.6 port won't be hard, if people are interested, I'll do it after
Thanksgiving.

I wrote it always custom tailored to the problem (it is not very difficult, but
you often have to tune it a bit until it has the right frequency to find the
corruption) Don't have one here right now, sorry.  Chris had a aimed to be 
generic patch for 2.4 that may still be around. I don't think it would fit 
into current LTP because it is an kernel module (LTP doesn't have a kernel build 
infrastructure right now).  But it would be an useful addition longer term to it 
I agree, once they support kernel modules.

Do you have your code posted anywhere, and when are you going to merge it
with LTP? ;)

One way to find slab corruptions qickly is to write a thrasher:
identify for which slab size the corruptions happens and then write a
small module that runs a thread that just allocates from that slab,
writes a pattern to it, sleeps a bit, and checks the pattern (allocate
multiple slabs to make it more effective). Repeat.

If you don't know the size cycle through the different cache sizes.

Me and Chris used that to track down some nasty corruptions on x86-64,
it is especially useful together with LTP which calls a lot of system
calls that could cause corruption.

Ok, this is quite possibly the ugliest patch I've ever made, but it might
catch some of the "use-after-free" issues with slab.

IT WILL NOT WORK IN GENERAL! In particular, you'll need to have tons of
memory free for this patch to work, since it basically scrapes off all the
regular slab code, and replaces it with some really nasty crud. I was
lazy. Whatever. It means that the slab memory balancing won't work etc,
but maybe somebody else can integrate my quick hack better.

It boots for me, but I won't say anything beyond that (oh, do NOT enable
slab debugging if you want to test this out - I pretty much guarantee it
won't work with this hack. You should enable DEBUG_PAGEALLOC instead,
and see if you get anything interesting out of that..).

There are a few reports of "predictable" memory corruption, in the sense
that the same people tend to see the same kinds of oopses _without_ any
other signs of memory corruption (ie no random SIGSEGV's in user space
etc).

There's the magic slab corruption thing, there's a strange thread data
corruption (one person), and there's the sunrpc timer bug. All are
"impossible" bugs that would indicate a small amount of data corruption in
some core data structure.

They are hard to trigger, which makes me personally suspect some
user-after-free thing, where the bug happens only when somebody else
allocates (and uses) the entry immediately afterwards (so that the old
user overwrites stuff that just got initialized for the new user).

It's not likely to be a wild pointer: those tend to corrupt random memory,
and that in turn is a lot more likely to result in _user_ corruptions
(causing SIGSEGV's, corrupted files that magically become ok again when
re-read, etc), since 99% of all memory tends to be non-kernel data
structures.

The PAGEFREE debug option works well for page allocations, but the slab
cache is not very amenable to it. For slab debugging, it would be
wonderful if somebody made a _truly_ debugging slab allocator that didn't
use the slab cache at all, but used the page allocator (and screw the fact
that you use too much memory ;) instead.

(Sadly, some slab users actually use that stupid "initialize" crap. We
should rip it out: it's a disaster from a data cache standpoint too, since
it tends to do all the wrong things there, even though it's literally
meant to help).

I've got that Oops while testing my fix of the tmscsim driver for 2.6. It
was test7. The driver worked, except in that only configuration, where
I've got the reported Oops. I just tried a working configuration (with
preempt enabled) and enabled DEBUG_PAGEALLOC - it still worked... So,
unless it REALLY was an impossible bug, that somehow impossibly
disappeared again (the only thing I can say - I couldn't have written that
Oops by hand just out of my head...:-)) - it should really be a
combination of all those parameters. I am currently recompiling test10
with that configuration, will try test7 again, if this one doesn't
reproduce the bug, will report results tomorrow. If I get the Oops again -
will attach the complete .config.

Thanks

Now take your .config and compare it with someone who is getting problems
with preempt, and others, and narrow it down.

Ah, I see. I thought there was a definite issue with a certain subsystem that
just hadn't been fixed yet when CONFIG_PREEMPT=y.

Indeed. Do the same subsystems usually show the memory corruption issue with
preempt active, or does it just pop up all over the place, unpredictably?

I've been running 2.6.0-test10 for a few hours on my P4M Asus laptop.
Playing music, editing files, compiling some things, some web surfing,
no problems.  Nothing unusual reported by the kernel.

Basically, there's something strange going on, which _seems_ to be memory
corruption, and seems to correlate reasonable well (but not 100%) with
CONFIG_PREEMPT.

It's actually unlikely to be preemption itself that is broken: it's much
more likely that some driver or other subsystem is broken, and preempt is
just better at triggering it by making some race conditions much easier to
see due to bigger windows for them to happen.

The problem is finding enough of a pattern to the reports to make sense of
what seems to be the common thread. A lot of people use preemption without
any trouble.

What sort of information would you like me to provide, sir? The bug you're
discussing here isn't affecting me; CONFIG_PREEMPT has been solid on 2.6.0-test10.
This is on a Gateway 600S laptop with a P4-M 2Ghz processor and an i845 Brookdale

I'd love to have more info - I actually looked at your original report,
and it's one of those "impossible" things as far as I can tell. The low
bit of the work "pending" flag should acts as a lock on workqueues, and
serialize access to one workqueue totally - so having it show up with a
pending timer is "strange" to say the least. The only two ways to clear
the "pending" timer is by running the work-queue - either for the timer to
have gone off (for the delayed case) _or_ the timer not to have evern been
set in the first place (for the immediate case).

So more information would be wonderful.

I've never enabled CONFIG_DEBUG_PAGEALLOC - the slowdown bit in the help text
never gave me a warm&fuzzy. If CONFIG_PREEMPT=y && CONFIG_DEBUG_PAGEALLOC=y,
perhaps the pagealloc debug code is exposing a messed-up preempt somewhere near
a memory allocation (IANAKC).

I found the thread regarding slab Oopsen where Linus mentioned CONFIG_PREEMPT
as a possiblity, but I'm not experiencing any issues with -test10 or -test9-bk22.
So I don't think the bug in that thread is affecting me at all, if it hasn't been
fixed.

Here's a candidate. I did have it on. Yes, I know it causes a slowdown -
that was for testing. I could try to double check, if disabling that
single option fixes the problem - but for that I'd need to recompile and
re-install kernel and modules... I also didn't have
CONFIG_DEBUG_STACKOVERFLOW switched on - but I don't think that could be

Hmmm. This is what I have enabled under "Kernel hacking":

#
# Kernel hacking
#
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_STACKOVERFLOW=y
CONFIG_DEBUG_SLAB=y
CONFIG_DEBUG_IOVIRT=y
CONFIG_MAGIC_SYSRQ=y
CONFIG_DEBUG_SPINLOCK=y
# CONFIG_DEBUG_PAGEALLOC is not set
# CONFIG_DEBUG_INFO is not set
CONFIG_DEBUG_SPINLOCK_SLEEP=y
# CONFIG_FRAME_POINTER is not set
CONFIG_X86_EXTRA_IRQS=y
CONFIG_X86_FIND_SMP_CONFIG=y
CONFIG_X86_MPPARSE=y

So far, though, not a single problem -- I was playing Flash animations while
printing a huge document without a single hiccup (I have an HP DeskJet 880C with
very little memory, so there was a lot of in-kernel activity).

Well, FWIW, I'm getting 100% reproducible Oopses on __boot__ by enabling
preemption AND (almost) all kernel-hacking CONFIG_DEBUG_* options - see my
post of 21.11.2003 with subject "[OOPS] 2.6.0-test7 + preempt + hacking".
If required, could try to narrow it down to 1 CONFIG option. However, the
Oops itself happens somewhere in NFS code (see backtrace in above email

I saw in Linus' 2.6.0-test10 announcement that preempt is suffering from some
problems and should not be used. However, I am currently running 2.6.0-test10
with CONFIG_PREEMPT=y and nothing has appeared yet. To see if the problem appeared
under stress, I started an A/V trailer playback with mplayer and then ran the
find command on both my home directory and the 2.6.0-test10 kernel source directory,
with the expected result - mplayer did not skip, neither find invocation broke,
and there were no nasty errors in dmesg.

So what exactly is the problem?

I can provide more system info on request.

TIA
