Fwd: 2.6.39-rc5-git2 boot crashs

[Linus Torvalds]

I dunno if you guys saw this. Any ideas?

Dave Chinner and Al Viro on the recipients because they were working
on iput_final etc locking changes. And logfs people for obvious
reasons.

The Code: line is buggered and seems to be missing one instruction
byte, and I think it's because the user used a web interface, and the
"<>" around the byte messed things up. But the code arount it decodes
to:

   0:	b8 30 4e 79 c2       	mov    $0xc2794e30,%eax   (probably
logfs_inode_lock address)
   5:	e8 41 a1 be 00       	call   xxx (probably _raw_spin_lock)
   a:	8d 8b f4 01 00 00    	lea    0x1f4(%ebx),%ecx
(li->li_freeing_list address)
  10:	8b 93 f4 01 00 00    	mov    0x1f4(%ebx),%edx  (li->li_freeing_list.next)
  16:	8b 83 f8 01 00 00    	mov    0x1f8(%ebx),%eax  (li->li_freeing_list.prev)
  1c:	89 42 04             	mov    %eax,0x4(%edx)   (next->prev = prev)
  1f:	89 10                	mov    %edx,(%eax)         (prev->next = next)
  ... something messed up ..
  29:	89 83 f4 01 00 00    	mov    %eax,0x1f4(%ebx)
  2f:	8d 86 54 02 00 00    	lea    0x254(%esi),%eax
  35:	89 83 f8 01 00 00    	mov    %eax,0x1f8(%ebx)

and that's basically the code that does:

  list_move(&li->li_freeing_list, &super->s_freeing_list);

and the removal from the old list has succeeded, but adding to the
super->s_freeing_list is failing.

It looks like a NULL pointer dereference with offset 4, so at a guess,
super->s_freeing_list.next is NULL, and it's the "next->prev = entry"
instruction that faults when inserting into that list.

How/why would s_freeing_list be NULL? I have no idea. But it looks
like a failed mount, so presumably it was never initialized.

Hmm. super->s_freeing_list is initialized pretty late in
logfs_read_sb(), and any error path _before_ that point will result in
a "goto err1" in logfs_get_sb_device() which will do various iputs
etc. All without that list initialized. That would seem to be the
cause of this, possibly triggered by Al's changes to ->mount from
read_super.

Somebody who knows the code better than me (ie any reasonably
well-educated squirrel) should take another look, though.

Werner, if this is easily repeatable for you, could you test just
moving up the lines that initialize the superblock mutexes and the
s_freeing_list to the top of logfs_read_sb() rather than the end (ie
move the three lines that do

        mutex_init(&super->s_dirop_mutex);
        mutex_init(&super->s_object_alias_mutex);
        INIT_LIST_HEAD(&super->s_freeing_list);

to be before the call to mempool_create(). That way those things will
be initialized much earlier, which is definitely what we want.

Whether that's the only problem and actually fixes it, I won't even
begin to guess, though.

Then it ought to be reproducible with much ealier kernels.  Say, 2.6.37 or
so...  That part of ->mount() series went in during last Autumn...

Wait a bit; _can_ we get there with non-NULL ->s_master_inode et.al.?
iput(NULL) is a noop...  I don't think so, since logfs_init_journal()
is not called until after we initialize that list.

Not that I'd object against taking that initialization earlier, of course,
but there seems to be something else going on...  Which iput() it is?

Not something I can guess from the oops, sadly. Gcc has inlined
everything into logfs_mount, and the "0x44f/0x5cc" offset isn't very
helpful (with the same compiler version and config options it would be
possible to figure it out).

But looking at it, logfs_init_mapping() is currently called before
"s_freeing_list" is initialized, and it sets up at least
s_mapping_inode. So if anything fails between that point and the point
where we initialize s_freeing_list, I think we're toast.

I didn't check the other inodes, but at least that one does seem to be
potentially non-NULL. No?

Ho-hum...  Point.  Let's take that initialization up to the beginning of
logfs_read_sb(), see if oops goes away and then try to figure out WTF
we hadn't been seeing it all along.  I don't see anything recent affecting
that area, but then logfs goes through many odd places during mount (including,
IIRC, mtd).  So there might be many sources of the failure where we used to
have none and failure in that spot would, indeed, fuck the things up that
way...

In any case, taking that initialization to the beginning of logfs_read_sb()
(if not up to its only caller where we set ->s_op et.al. anyway) seems to be
the obviously right thing to do.  Unless logfs folks have some subtle
objections?

Re: 2.6.39-rc5-git2 boot crashs

[werner]

At my reclamation thread about 2.6.39-rc3,4 crashs, I 
informed that there was a reset-resistent change of the 
system after crashs, so that on subsequent boots (after a 
'primary' crash rather at the end of booting) it happened 
an early 'secondary'  crash at the time of initializing 
ata0, with funny effects like that the grafic card (or 
anything else) was identified as an ata device, with 
subsequent 'read erros' on it and crash. This 'secondary' 
effect repeated and repeated and gone away only at booting 
with a normal kernel (2.6.38.4 or 2.6.26.2). But if 
afterwards booting again with 2.6.39-rc3 or -rc4 , then at 
the end of the boot it crashed, and at subsequent boots 
again continued this reset-resistent effect that it crasha 
again and again with ata0 problems, until I reboot with 
2.6.38.4 or 2.6.26.2 , or waiting 5 minutes (perhaps until 
the memory discharged).

All these problems dont happen with 2.6.38.4 or 2.6.26.2

Do you think you could bisect when that odd after-reset behavior started?

It does sound like you have some PCI-level problem (some device that
has "sticky" state and doesn't get reset properly). Most likely a
hardware "feature" (there is various PCI hardware that allows things
like device identifiers to be written to), coupled with a firmware bug
that doesn't reset things.

But it would be intriguing to hear when it started happening, so that
we can figure out exactly _what_ isn't getting properly reset..

The logfs oops may just be a result of "autodetect any random
filesystem" in that confused state. So when the state isn't confused,
you'd not see the oops, because nothing ever tries to mount the
invalid logfs image.

[-- Attachment #1: Type: text/plain, Size: 1940 bytes --]

Enclosed the config and compilation log file (with some 
warnings, things which should be corrected also). Perhaps 
it's useful for find the error.

Right now my computer crashed again when I unzipped a big 
file.  As said in the 2.6.39-rc1 until -rc4 reclamations, 
 the computer always crashs if zip, unzip or move big 
files.  This looks like an error of the memory / paging 
driver.

w.r.t. my last message, it should be ata1 rather than ata0 
.  ( See, enclosed a foto of such reboot-resistent 
secondary crashs (happened after a big primary crash) on 
which 'anything' was interpreted as ata )

Re: 2.6.39-rc5-git2 boot crashs

[werner]

The problem that the computer crashs if zip, unzip or move 
a big file, started with -rc1

The problem with the secondary reset-resistent crashs 
after a primary and-of-boot or after-boot crash started 
with -rc3 or -rc4, at least I perceived it then, but it's 
possible that it occured also before, at least then I 
didn't note it

Now I see, that nor the syslog don't contain everything 
(this was also better with 2.6.38.4).  For example, 
currently aren't logged these crashs which currently 
occure during rtc0 initializing (in addition to the other 
crashs protocolled in the log files). Also, as you can see 
from my before-last message, with the screen foto of 
/dev/pts/0 w.r.t. boot_vga, this also don't appear in the 
log file which was added at the end of the same message.

For being -rc5 , that kernel is rather bad.  I hope you 
get through to correct it until -rc10

Quite frankly, right now I think you're the only one that has reported
these kinds of problems, so we will need to rely on you to figure out
what is so odd about your setup.

If you can pinpoint when the crashes happened, that would help a lot.

Also, the crash that happens not-at-boot is in many ways way more
important. Clearly you have something odd going on after a reboot, and
I'd love to figure that out too, but in many ways the unzip one is way
more important.

Sadly, your previous mail had a nice picture, but the important
information had scrolled off the screen because of the ata1 exception
and command failed printouts. Any chance you could get a picture of
just the oops? If worst comes to worst, you might even have to disable
those ata debug printouts (normally they are really important, but if
they make the earlier oops scroll off the screen, they hurt more than
they help).

Oh, and please do an lspci -vvxx and a working dmesg too for that machine.

Re: 2.6.39-rc5-git2 boot crashs

[werner]

For your information:
/ All these problems dont have with 2.6.38 , .1, .2, .3 , 
.4
/ At 2.6.38-rc1 or was it 37-rc1 there had a problem with 
khugepaged what I also reclaimed.  That was similar like 
now these crashs which are NOT visible in syslog, 
happening a few minutes until hours after booting (these 
crashs should be visible in syslog 10..30 seconds before I 
rebooting).   At that time, the problem was corrected with 
khugepaged.   But it's possible, that the correction at 
that time wasn't good enough, so that now, after some 
other changes, the same problem 'returned'.  Currently, 
since 2.6.39-rc1 it crashs ALWAYS if I zip or unzip files 
of some 100 M  or move big files.     It's possible that 
it is a problem with the memory administration.
/ I use gcc 4.3.3 and glibc 2.9
I hope this informations are useful for correct these 
problems.

Pls see enclosed:

/ lspci   -vvxx
/ dmesg

with 2.6.39-rc5-git2.


One minute later, it crashed again.   The screen foto, 
I'll send in a next e-mail in a few seconds, because here 
I can add only 3 files.    After, I rebooted with 2.6.38.4 
, what's stable and never crashed.   For comparison,

/ dmesg

with 2.6.38.4 (from just now) is added also.

I dont know if in the syslog is recorded what happened 
before the ata1 crash, I'll search it.

Enclosed a part of the syslog of the time when I made the 
screen
foto with the ata1 problem. Unfortunately, neither the 
watch of my computer, nor
of my handy is exact and also the system time of the foto 
may be when I copied it
to the computer, so that I don't know exactly to which of 
the boots the foto was
refered -- but it's also quite possible that this ata1 
crashs are neither logged
in syslog, like actually some crashs at rtc0 aren't 
logged.  MORE UNFORTUNATELY,
THE LOG FILE NOR SHOWS THE KERNEL VERSION AT BOOT TIME 
(YOU SHOULD IMPROVE THIS !!!),
  SO THAT THE BOOTS ARE REFERED SOMETIMES TO 2.4.38.3 or 
.4, SOMETIMES TO 2.6.39-RC3
or RC4 . However, I hope the log file is useful for 
something.

Ok.

So what strikes me is that it looks like you're basically booting a
"allyesconfig" kernel, or at least something that has a _ton_ of crazy
drivers and filesystems that are entirely irrelevant for your setup.

And I'm wondering whether your problems are due to some buggy driver
that stomps on something that it shouldn't. It's clearly a regression
(your 2.6.38.4 dmesg shows the same "lots of irrelevant drivers and
filesystems" issue, but works for you), but it may explain why others
aren't seeing the problem. Your 2.6.39-rc5 dmesg does have a few new
drivers in it, and that seems to be because they simply didn't exist
back in 2.6.38 (but I didn't check).

So your lspci shows a AMD system with a nvidia chipset:

and in particular, your IDE/SATA controllers are clearly nVidia. But
the generic IDE driver seems to be a bit confused:

  Uniform Multi-Platform E-IDE driver
  amd74xx 0000:00:06.0: UDMA133 controller
  amd74xx 0000:00:06.0: IDE controller (0x10de:0x03ec rev 0xa2)

  ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
  ide_generic: please use "probe_mask=0x3f" module parameter for
probing all legacy ISA IDE ports

but that shouldn't matter, since it doesn't actually find anything there.

But could you try using a more reasonable config, and see if the
problem goes away? Don't configure logfs (you don't use it), don't
configure all the crazy random SCSI drivers, don't configure all the
laptop drivers etc (that cause various management drivers to be loaded
even though you don't even have the hardware afaik):

 ...
  XGIfb: Options (null)
  asus_wmi: Asus Management GUID not found
  asus_wmi: Management GUID not found
  asus_wmi: Management GUID not found
  msi_laptop: driver 0.5 successfully loaded.

  hp_accel: driver loaded
  hdaps: supported laptop not found!
  hdaps: driver init failed (ret=-19)!
  fujitsu-laptop: driver 0.6.0 successfully loaded.
  This machine doesn't have MSI-hotkeys through WMI
  Topstar Laptop ACPI extras driver loaded
 ...

because if any of them corrupt memory or something like that, we
obviously want to find that bug, but we don't want to think it's some
bug in the drivers you actually _use_.

So if you could try a minimal config that supports only the hardware
(and filesystems) you actually _have_ and use (ie just disable IDE
entirely - you don't want it, you want the SATA_nv driver), that would
be great. Does that work better for you?

And if it does work better, then it would be really interesting to
start enabling things again, and see what causes the problem.

Ok?

I DO NOT CARE WHY YOU ENABLE EVERYTHING.

I want to know what makes it start to fail. We simply don't know why
you see this problem (and apparently your friend too), but one issue
may be a totally unrelated buggy driver.

In order to figure it out, you need to help us. And one thing that is
very odd and wrong about your setup is how you have compiled in
absolutely everything.

And yes, it's wrong, because the way to do distro kernels is to
compile in the sane and common stuff, and load the rest as modules as
required.

And that's exactly because

 (a) some drivers cannot sanely auto-detect if they are needed
(sometimes they are just buggy, but often it's because the hardware
they drive is not sane and doesn't necessarily have any nice
enumeration model)

 (b) bugs happen. They happen especially commonly with rare hardware,
since that by definition gets less testing (that rare hardware can
often be "high-end" hardware - you'd think they are higher quality,
but the reverse is usually true).

Probing absolutely everything at boot-time tends to just be more
dangerous. There's a reason why most distros ask something like "are
you using just standard devices, or specialized storage subsystems",
so that they don't need to worry about the rare and possibly buggy
cases quite as much.

Some drivers you enable tend to be more about embedded systems (ie the
whole MTD layer etc), and there's likely little reason to do that in a
standard distribution kernel at all.

It's clearly a regression. Nobody disputes that. But you need to help
us find it. So just do a minimal kernel. Please. So that we can say
either "yes, it still shows up even when you only have the normal
drivers", or we can say "ok, it's one of the uncommon drivers that
screws things up".

And it's not just drivers. Please disable things like virtualization
etc kernel features if you don't need it.

We cannot fix it if we cannot pinpoint what the problem is. We won't
ignore it if the problem goes away when you have disabled drivers - at
that point I'm going to ask you to try to enable the drivers and
features until it starts happening again, so that we know _what_
random thing is causing it.

And please stop arguing against people who are trying to help figure
out what is wrong, ok?

With your "everything enabled" kernel, right?

If you don't want to minimize the configuration, you'll need to at
least bisect _exactly_ where the problem starts. There's about ten
thousand commits, spanning the whole kernel, in between 38 and 39-rc1.
We don't know what's wrong right now. And you are currently the only
one seeing, along with your friend who presumably uses your kernel. So
there's something wrong that is triggered by something specific to
YOUR setup.

See what I'm trying to say here?

Re: 2.6.39-rc5-git2 boot crashs

[werner]

Since years it's all the time that I compile the kernel 
with everything enabled, because these kernel builds are 
for a distro, and should work on any computer.  Normally, 
things going stable at -rc3 or -rc4 , often already at 
-rc2.

Beside of with my computer, essentially the same problems 
also happens with a laptop of a friend.

Also, a big problem are the (after-boot-) crashs if 
zipping / unzipping big files.  Packages I can build only 
with 2.6.38.4, not with 2.6.39-rcX

Below is the diff between the config of 2.6.38.4 and 2.6 
39-rc5-git3 .  You could inspect them what potentially 
could explain the reported problems.  But I think at least 
the problems which happens on my computer, and on that of 
the friend, are regressions, because none of the new 
staging drivers we use.
