Description Sami Liedes 2008-06-07 09:19:33 UTC
Latest working kernel version:
Earliest failing kernel version:
Distribution: Debian sid (unstable)
Hardware Environment: qemu x86
Software Environment: Minimal Debian sid
Problem Description:

The attached (intentionally) broken ext3 images break ext3 in different ways.

Steps to reproduce:

For hdb.25.softlockup.gz:

1. gunzip the image
2. mount hdb.25.softlockup /mnt -o loop
3. cd /mnt
4. find >&/dev/null
   -> lockup

For hdb.20000009.softlockup.gz:

1. gunzip the image
2. mount hdb.20000009.softlockup /mnt -o loop
   -> orphan list check failed, lockup

For hdb.20000057.nullderef.gz:

1. gunzip the image
2. mount hdb.20000057.nullderef /mnt -o loop
3. rm -rf /mnt
   -> oops

Hi Sami,

Thanks for the report.

(In reply to comment #1)
> The attached (intentionally) broken ext3 images

Could you describe how you proceeded (fsfuzzer, killing qemu?)

> break ext3 in different ways.

Did you try e2fsck before trying to mount the images?

I briefly tested the first case and it seems ok after "e2fsck -y" (on Debian Sid 
e2fsprogs 1.40.8-2).

I am not clear about what is the expected behavior here.

On the one hand, every program should check its inputs, on the other hand, it may be the job of e2fsck to check filesystems (before passing them to the kernel). But checks are expensive. Maybe mount should trigger the fsck...

This seems to be a borderline case, with expected behavior depending on how the corruption happened, or if the mount triggers something not strictly related to the corruption.

Will try to figure out...

I think it would be better to fill separate issues for each corruption (this way subject can be refined as analysis progresses).

Comment 5 Sami Liedes 2008-06-09 02:54:49 UTC
Hi,

I use the zzuf program (google for it, or Debian package zzuf), which just flips each bit in the image with a preset probability. Here's a script I use inside qemu (varying some of the parameters):

-----
#!/bin/sh

if [ "`hostname`" != "fstest" ]; then
   echo "This is a dangerous script."
   echo "Set your hostname to \`fstest\' if you want to use it."
   exit 1
fi

umount /dev/hdb
umount /dev/hdc
/etc/init.d/sysklogd stop
/etc/init.d/klogd stop
/etc/init.d/cron stop
mount /dev/hda / -t ext3 -o remount,ro || exit 1

ulimit -t 20

for ((s=$1; s<1000000000; s++)); do
  umount /mnt
  echo '***** zzuffing *****' seed $s
  zzuf -r 0.0001:0.05 -s $s </dev/hdc >/dev/hdb || exit
  mount /dev/hdb /mnt || continue
  cd /mnt || continue
  cp -r doc doc2 >&/dev/null
  find -xdev >&/dev/null
  find -xdev -print0 2>/dev/null |xargs -0 touch -- 2>/dev/null
  mkdir tmp >&/dev/null
  echo whoah >tmp/filu 2>/dev/null
  rm -rf /mnt/* >&/dev/null
  cd /
done
-----

The kernel dying (or worse, if it can be exploited to execute arbitrary code) on mounting corrupted filesystems can be a problem at least on the currently quite common setup on e.g. universities, since many modern distributions allow the user to plug in a USB memory stick and mount it. It's quite easy for a malicious user to put an arbitrary file system on an USB stick.

So at least if the crashes are easily avoidable by changing the code, I think it definitely should be done. It also means more robustness against unintentionally corrupt code.

No, I didn't try e2fsck, since my intention was to get the kernel to crash.

Thanks for the nice script!

Or worse: a malicious DPL :-)

I see the misuse case: privilege escalation with carefully crafted corrupted fs.

I would say kernel dying is less worrisome since physical access to plug USB stick probably means also access to pull the power plug or more creative ways to crash or damage the machine via the USB connector.

Back in the days, we used mtools to access data on removable media at the University. It still works with USB sticks.

Agreed.

This leaves the question "which code?" (kernel, mount, mounting scripts, security levels,...).

> No, I didn't try e2fsck, since my intention was to get the kernel to crash.

The 3 images do not seem to issue errors after e2fsck.

Comment 7 Solofo Ramangalahy 2008-06-10 00:07:43 UTC
Testing on 2.6.26-rc5:

. hdb.25.softlockup reproduced

. hdb.20000009.softlockup not reproduced (mount running taking 100% cpu, unkillable)

. hdb.20000057.null.deref oops not reproduced, no error on console, rm gives error:
"
rm: WARNING: Circular directory structure.
This almost certainly means that you have a corrupted file system.
NOTIFY YOUR SYSTEM MANAGER.
The following directory is part of the cycle:
  `/mnt/test/doc/adduser/examples/adduser.local.conf.examples/skel.o4her/index.html/index.html/index.html'
"
Comment 8 Duane Griffin 2008-06-20 08:30:39 UTC
The first case, hdb.25.softlockup, is happening inside ext3_dx_find_entry. It is caused by ext3_next_entry being used to iterate through directory entries without checking for the rec_len == 0 case.

There are a number of places in fs/ext3/namei.c where similar usage seems problematic. I'll look into fixing them.
Comment 9 Sami Liedes 2008-06-20 08:45:45 UTC
Hi,

If you have any experimental patches, I can try them and rerun the tests to validate them and find more problems if you wish. Of course you can do that yourself too with the script in #5, but it does require some setting up.
Comment 10 Duane Griffin 2008-06-20 09:33:04 UTC
Thanks, I'll let you know. I've reproduced it here, so hopefully we won't need too much back & forth.
Comment 11 Duane Griffin 2008-06-21 10:19:27 UTC
Hi Sami, you should have received my patch for case 1 via email (the second version should be fine to test with, despite the typo already pointed out in it). Let me know if it works for you.

For case two it looks like the orphan list is pointing at a valid non-orphaned inode. Since it is valid it doesn't get processed and removed from the orphan list and we keep looping around. I'm looking into the best way to fix that now.
Comment 12 Sami Liedes 2008-06-22 10:53:33 UTC
The patch for case 1 seems to resolve at least that crash. Running tests now to see if I can get some new kind of crashes.

By the way, do you think it would be more productive for me to run the tests with latest stable rc (or even 2.6 head) rather than the latest stable? It's basically no extra work for me since I have to compile a minimal non-modular version of the kernel anyway.
Comment 13 Duane Griffin 2008-06-23 17:46:43 UTC
> By the way, do you think it would be more productive for me to run the tests

I'm not sure. On one hand, you might find new bugs before they went into a release and you wouldn't find already fixed bugs. On the other, it would be more work for you and you may find transient issues that are already being worked on, especially if you track the head.

I'd say what you're currently doing is very valuable and working well at finding real existing bugs. Perhaps you should keep on as you are for now and switch to testing -git if and when you stop finding unfixed bugs.
Comment 14 Duane Griffin 2008-06-23 19:35:59 UTC
I still see the OOPS with case 3 with recent git. Looks like the following line from journal_dirty_metadata in fs/jbd/transaction.c:

if (jh->b_modified == 0) {

Which implies bh->b_private is corrupted.
Comment 15 Sami Liedes 2008-06-24 12:50:32 UTC
These cases seem to be now fixed by the various patches you sent to lkml and me. I found one more soft lockup even with your patches applied and filed a separate bug, #10976.
Comment 16 Duane Griffin 2008-06-24 17:23:35 UTC
Thanks, Sami. Excellent work with the testing. I'll take a look at the new bug and comment there. I'm not sure what the usual procedure for closing these tickets is but I suppose once the patches hit mainline would be a sensible time to do so.
Comment 17 Adrian Bunk 2008-07-15 13:16:19 UTC
the fixes are now in Linus' tree
Comment 18 Sami Liedes 2008-08-04 15:42:15 UTC
I can reproduce the crash with attachment #1 [details] (hdb.25.softlockup) with 2.6.26.1, so reopening this bug. The stack trace is slightly different, but the steps to reproduce are same. Here's the backtrace:
