Description Matthew Stapleton 2005-07-26 21:17:55 UTC
Distribution: Gentoo 
Hardware Environment: Athlon XP 2000+ on Via Tech KM133, also tried on Athlon   
Thunderbird 1000 on Via Tech KT133 
Software Environment: Linux using ReiserFS filesystems on LVM on software   
RAID 1 
Problem Description: 
When reading certain large files, I get random data returned for portions of  
those files.  I noticed this when doing an sha1sum on a large iso file and  
noticed every time I ran sha1sum it returned a different result.  The  
filesystem is not corrupted though.  Reiserfsck returns no errors and doing  
sha1sum on the LVM device that the file system is on always returns the same  
result.  Also, when I go back to vanilla kernel 2.6.10 or below, that same file  
that seemed to be corrupted returns its expected sha1sum. 
 
The following kernels have this problem: 
  2.6.11 
  >=2.6.10-hardened-r3 (Gentoo) 
  2.6.12-gentoo-r6 (Gentoo) 
 
Steps to reproduce: 
I'm not sure how to trigger the problem, but on my system the filesystem is  
nearly out of space and once a file is created that triggers the bug, it will  
trigger the bug everytime.  My next step is to remove certain patches from 
2.6.10-hardened-r3 to see if I can isolate the code causing the problem then if 
that doesn't work I'll try the test kernels leading up to 2.6.11. 
 
In case it helps here is the config I've been using to test this problem:

Comment 1 Matthew Stapleton 2005-07-27 07:27:07 UTC
Update: kernel 2.6.11-rc1 doesn't have this bug but 2.6.11-rc2 does. 
Comment 2 Andrew Morton 2005-07-27 09:48:55 UTC
That's helpful.

There are no significant reiserfs changes between 2.6.11-rc1 and 2.6.11-rc2.

There's one small change in drivers/block/md.c but it looks fairly innocent.
To test that you could run a 2.6.11-rc2 kernel with 2.6.11-rc1's md.c

But I'd more be suspecting block and/or device driver problems.

What device driver are you using there?

And have you eliminated the "hardened" patches from the picture?
Comment 3 Matthew Stapleton 2005-07-27 23:40:21 UTC
I am using the IDE VIA82CXXX and Device Mapper for LVM2.    
    
Since 2.6.10-hardened-r3 uses 2.6.10-ac10 as its base I tested 2.6.10-ac9 and   
2.6.10-ac10.  2.6.10-ac9 doesn't have the bug but 2.6.10-ac10 does.  Then by   
examining the few files that had changed I found out that the change in   
fs/bio.c is what is causing the problem.  This same change occurred between   
2.6.11-rc1 and 2.6.11-rc2.  Also, the problem still occurs in 2.6.13-rc3.  
  
In case it helps, I have 1 LVM2 physical volume spanning 5 20008832 block RAID  
1 partitions and 1 14056768 block partition.  The LVM2 logical volume  
containing the 'corrupt' test file is 35GB, spans 2 segments and uses a  
ReiserFS filesystem.  Unfortunately, I can't seem to get any other copies of  
large files to trigger the bug at the moment. 
Comment 4 Andrew Morton 2005-07-27 23:48:14 UTC
Fantastic work, thanks.   I'll ping a few people..
Comment 5 Andrew Morton 2005-07-27 23:54:47 UTC
Created attachment 5394 [details]
bio_clone fix

Could you please try this fix?
Comment 6 Jens Axboe 2005-07-28 00:55:32 UTC
Andrew, please pass that patch on to Linus right away.
Comment 7 Matthew Stapleton 2005-07-28 02:38:43 UTC
I tested that patch and it fixes the problem on 2.6.11, 2.6.12, and 2.6.13-rc3
Comment 8 Adrian Bunk 2005-08-03 05:43:37 UTC
The patch is now included in 2.6.13-rc and scheduled for inclusion in 2.6.12.4 .
Comment 9 Adrian Yee 2005-08-05 12:57:39 UTC
What about that comment a few lines up?

        /*
         * notes -- maybe just leave bi_idx alone. assume identical mapping
         * for the clone 
         */

From that comment, it sounds like the original author had been doing the bi_idx
copy, but it was removed later on (and the comment was left in).  And now bi_idx
is being copied again.
Comment 10 Jens Axboe 2005-08-05 13:16:08 UTC
The author is me and the change is fine, probably the comment should be killed
as well, but lets just leave it. Most users will expect the clone to have the
same index as the original, so it's was a bad judgement.
Comment 11 Andrew Morton 2005-08-05 13:46:15 UTC
heh, yeah, thanks.  I'll kill that comment.
