Hi guys,

before diving into testing out 2.6.37-rc* kernels I wanted to make
sure that the patch:

[dm-devel] [PATCH] DM-CRYPT: Scale to multiple CPUs v3

is safe to use with e.g. >2.6.37-rc1 kernels

I know that it's not a "fix all" patch but it significantly seems to
speed up my backup jobs (by factor 2-3)
and 2.6.37* has evolved that much that interactivity isn't hurt too much

Thanks !

Matt

yes, it should work for the simple mappings without problems.

I hope we will fix the patch soon to be ready for upstream.

Hi Milan,

thanks for your answer !

Unfortunately I have to post a "Warning" that it's currently not safe
(at least for me) to use it

a few hours ago before 2.6.37-rc1 was tagged I already had shortly
tested it with the dm-crypt multi-cpu patch and massive "silent" data
corruption or loss occured:

fortunately I don't/didn't see any data-corruption on my /home
partition (yet) but everytime I boot into my system things are screwed
up on the root-partition, e.g.:

where
eselect opengl list would show
Post by Milan Broz
[1] ati *
[2] xorg-x11
normally it's
Post by Milan Broz
cat /etc/env.d/03opengl
# Configuration file for eselect
# This file has been automatically generated.
LDPATH="/usr/lib32/opengl/ati/lib:/usr/lib64/opengl/ati/lib"
OPENGL_PROFILE="ati"
eselect opengl list
[1] ati
[2] xorg-x11
cat /etc/env.d/03opengl
# Configuration file for eselect
and another example was a corrupted /etc/init.d/killprocs

so since this (a corrupted killprocs) already had happened in the past
(last time due to a hardlock with fglrx/amd's catalyst driver) I
thought it was some kind of system problem which could be fixed:
I fired up a rebuild-job (emerge -e system) for my system and (surely)
some other stuff disappeared - after 2-3 reboots I wanted to continue
finishing the rebuild and gcc was gone (!)

I don't have the time to re-test everything since this is my testing &
production machine (I'll play back a system-backup tarball) but this
didn't happen (yet) with 2.6.36 and
the following patches related to multi-cpu dm-crypt:

* [dm-devel] [PATCH] DM-CRYPT: Scale to multiple CPUs v3
* [PATCH] Use generic private pointer in per-cpu struct

so it seems to be safe.

It has to be changes which got introduced with 2.6.37* which broke
stuff. 2.6.36 seems to work perfectly fine with those 2 patches since
several days already

I'll stick with 2.6.36 for some time now

Thanks !

sorry - I forgot to include the most important part:

the system-partition is on an LVM/Volume Group that sits on an
cryptsetup partition so:

cryptsetup (luks) -> LVM/Volume Group (2 partitions, one of them
system - the other swap) -> system (ext4)

[cryptsetup -> LVM -> ext4-partition]

the mount-options were/are:

noatime,nodiratime,barrier=1

sometimes also

noatime,nodiratime,barrier=1,commit=600
(when the system runs for several hours to make it consume less
energy/write less)

the other settings are:

echo "3000" > /proc/sys/vm/dirty_expire_centisecs
echo "1500" > /proc/sys/vm/dirty_writeback_centisecs
echo "15" > /proc/sys/vm/dirty_background_ratio
echo "50" > /proc/sys/vm/dirty_ratio
echo "50" > /proc/sys/vm/vfs_cache_pressure

i/o scheduler: cfq

as already mentioned - this problem didn't appear or wasn't noticable
(yet) with or until 2.6.36 - my system-memory should also be
error-free (tested via memtest86), the harddisk too (previously tested
several times via badblocks without errors)

during every shutdown, reboot, hibernate, etc.

I do a manual:

sync && sdparm -C sync /dev/foo

to make sure data gets to the partition

I read about barrier-problems and data getting to the partition when
using dm-crypt and several layers so I don't know if that could be
related

Regards

Barriers seem to be totally broken on dm-crypt currently.

But that's probably not your problem. I use the scalability patch
on 2.6.36 and it's very stable. Most likely some mistake
in the forward port.

Can you explain it?

Barriers/flush change should work, if it is broken, it is not only dm-crypt.
(dm-crypt simply relies on dm-core implementation, when barrier/flush
request come to dmcrypt, all previous IO must be already finished).

linux-btrfs? I'm not subscribed, but I the searches I've tried
don't show it to be "full of corruption reports".

Could you post links to the threads concerned so we can investigate?

Are we just talking -rc1 or earlier too?

Thanks,
Alasdair

[cc'ing linux-btrfs, hopefully in the future dm-devel will get cc'd when
concerns about DM come up on linux-btrfs (or other lists)]

I spoke with Josef Bacik and these corruption reports are apparently
against older kernels (e.g. <= 2.6.33). I say <= 2.6.33 because:

https://btrfs.wiki.kernel.org/index.php/Gotchas states:
"btrfs volumes on top of dm-crypt block devices (and possibly LVM)
require write-caching to be turned off on the underlying HDD. Failing to
do so, in the event of a power failure, may result in corruption not yet
handled by btrfs code. (2.6.33)"

But Josef was not aware of any reports with kernels newer than 2.6.32
(F12).

Josef also noted that until last week btrfs wouldn't retry another
mirror in the face of some corruption, the fix is here:
http://git.kernel.org/?p=linux/kernel/git/mason/btrfs-unstable.git;a=commit;h=cb44921a09221

This obviously doesn't fix any source of corruption but it makes btrfs
more resilient when it encounters the corruption.

Can you please be more specific? What test(s)? What kernel(s)?

Any pointers to previous (and preferably: recent) reports would be
appreciated.

The DM barrier code has seen considerable change recently (via flush+fua
changes in 2.6.37). Those changes have been tested quite a bit
(including ext4 consistency after a crash).

But even prior to those flush+fua changes DM's support for barriers
(Linux >= 2.6.31) was held to be robust. No known (at least no
reported) issues with DM's barrier support.

I think it would be best to move forward with just hammering on the
dm-crypt barriers:

This script is the best I've found so far to reliably trigger
corruptions with barriers off. I'd start with ext3 + barriers off just
to prove it corrupts things, then move to ext3 + barriers on.

I started with ext4 + barrier=0,journal_async_commit and could reliably
cause directory corruption (~75% of the time). I then switched to
barrier=1 and could not cause corruption.

I then added dm-crypt and got the same results: with barrier=1 I could
not cause directory corruption. barrier=0 resulted in directory
corruption (again ~75% of the time), no corruption occurred with
barrier=1.

Both 2.6.36 (original barrier code) and latest 2.6.37-rc1+ (new
flush+fua code) were tested. 6 iterations of barrier=0 and 10
iterations of barrier=1.

So my hope is we can now put this general dm-crypt barrier doubt to one
side and work together on identifying the cause of corruption when
dm-crypt is paired with btrfs.

Hi Mike,

I'm pretty sure that dm-crypt is rockstable :)

My report wasn't meant to be / cause FUD sorry if it got picked up that way:

with the vanilla dm-crypt implementation I saw *NO* corruption at all
in the small testing amount of time I ran it
however as soon as I applied the

[dm-devel] [PATCH] DM-CRYPT: Scale to multiple CPUs v3
and
[PATCH] Fix double free and use generic private pointer in per-cpu

patches, recompiled the kernel and rebooted into that new environment

it seemingly caused corruptions right from the start (the mentioned
corruption /etc/env.d/02opengl to be the most obvious candidate and
probably even more)
with those corruptions being anticipated over longer uptime and heavy
use-patterns (such as re-compiling the whole system).

I don't know if the new multi-cpu scaling patch for dm-crypt makes a
change (since I can't test it right now due to a busy schedule)

[PATCH v5] dm crypt: scale to multiple CPUs

I however have a request:

could you guys please take this patch through a "battery of heavy
tests" until it's included in mainline ?

so that you can spot any issues (races, BUGs, etc.) which might be
inherent/triggered in current dm-crypt so that my reported corruptions
might be prevented in the future ?

Again:

the vanilla kernel and dm-crypt are perfectly stable !

only with the dm-crypt scaling patch I could observe the data-corruption


Thanks !

even with v5 I sent on Friday?

Are you sure that it is not related to some fs problem in 2.6.37-rc1?

If it works on 2.6.36 without problems, it is probably problems somewhere
else (flush/fua conversion was trivial here - DM is still doing full flush
and there are no other changes in code IMHO.)

only with the dm-crypt scaling patch I could observe the data-corruption
even with v5 I sent on Friday?
Are you sure that it is not related to some fs problem in 2.6.37-rc1?
If it works on 2.6.36 without problems, it is probably problems somewhere
else (flush/fua conversion was trivial here - DM is still doing full flush
and there are no other changes in code IMHO.)
Milan
Hi Milan,

I'm aware of your new v5 patch (which should include several
improvements (or potential fixes in my case) over the v3 patch)

as I already wrote my schedule unfortunately currently doesn't allow
me to test it

* in the case of no corruption it would be nice to have 2.6.37-rc* running :)

* in the case of data corruption that would mean restoring my system -
since it's my production box and right now I don't have a fallback at
reach
at earliest I could give it a shot at the beginning of December. Then
I could also test reiserfs and ext4 as a system partition to rule out
that it's
a ext4-specific thing (currently I'm running reiserfs on my system-partition).

Thanks !

OK guys,

I've updated my system to latest glibc 2.12.1-r3 (on gentoo) and gcc
hardened 4.5.1-r1 with 1.4 patchset which also uses pie (that one
should fix problems with graphite)

not much system changes besides that,

with those it worked fine with 2.6.36 and I couldn't observe any
filesystem corruption



the bad news is: I'm again seeing corruption (!) [on ext4, on the /
(root) partition]:

I was re-emerging/re-installing stuff - pretty trivial stuff actually
(which worked fine in the past): emerging gnome-base programs (gconf,
librsvg, nautilus, gnome-mount, gnome-vfs, gvfs, imagemagick,
xine-lib) and some others: terminal (from xfce), vtwm, rman, vala
(library), xclock, xload, atk, gtk+, vte

during that I noticed some corruption and programs kept failing to
configure/compile, saying that g++ was missing; I re-extracted gcc
(which I previously had made an backup-tarball), that seemed to help
for some time until programs again failed with some corrupted files
from gcc

so I re-emerged gcc (compiling it) and after it had finished the same
error occured I already had written about in an previous email:
the content of /etc/env.d/03opengl got corrupted - but NOT the whole file:

normally it's
# Configuration file for eselect
# This file has been automatically generated.
LDPATH=
OPENGL_PROFILE=
<-- where the path to the graphics-drivers and the opengl profile is written;

in this case of the corruption it only where @@@@@@@@@@@@
symbols


I have no clue how this file could be connected with gcc


===> so the No.1 trigger of this kind of corruption where files are
empty, missing or the content gets corrupted (at least for me) is
compiling software which is part of the system (e.g. emerge -e
system);

the system is Gentoo ~amd64; with binutils 2.20.51.0.12 (afaik this
one has changed from 2.20.51.0.10 to 2.20.51.0.12 from my last
report); gcc 4.5.1 (Gentoo Hardened 4.5.1-r1 p1.4, pie-0.4.5) <--
works fine with 2.6.36 and 2.6.36.1

I'm not sure whether benchmarks would have the same "impact"



the kernel currently running is 2.6.37-rc4 with the [PATCH v5] dm
crypt: scale to multiple CPUs

besides that additional patchsets are applied (I apologize that it's
not only plain vanilla with the dm-crypt patch):
* Prevent kswapd dumping excessive amounts of memory in response to
high-order allocation
* ext4: coordinate data-only flush requests sent by fsync
* vmscan: protect executable page from inactive list scan
* writeback livelock fixes v2

I originally had hoped that the mentioned patch in "ext4: coordinate
data-only flush requests sent by fsync", namely: "md: Call
blk_queue_flush() to establish flush/fua" and additional changes &
fixes to 2.6.37-rc4 would once and for all fix problems but it didn't

I'm also using the the writeback livelock fixes and the dm-crypt scale
to multiple CPUs with 2.6.36 so those generally work fine

so it has be something that changed from 2.6.36->2.6.37 within
dm-crypt or other parts that gets stressed and breaks during usage of
the "[PATCH v5] dm crypt: scale to multiple CPUs" patch

the other included patches surely won't be the cause for that (100%).

Filesystem corruption only seems to occur on the / (root) where the
system resides -

Fortunately I haven't encountered any corruption on my /home partition
which also uses ext4 and during rsync'ing from /home to other data
partitions with ext4 and xfs (I don't want to try to seriously corrupt
any of my data so I played it safe from the beginning and didn't use
anything heavy such as virtualmachines, etc.) - browsing the web,
using firefox & chromium, amarok, etc. worked fine so far

the system is in a pretty "new" state - which means I extracted it
from a tarball out of an liveCD environment with 2.6.35 kernel to the
harddrive - 1st boot was to and 2.6.36 kernel where the 2.6.37-rc4*
kernel was compiled
2nd boot -> current uptime 4 hours

harddrive: Samsung HD203WI (no bad blocks reported by smartmontools,
also no corruptions reported by a run of badblocks (the tool) itself)

harddrive -> cryptsetup -> LVM (volume group: system and swap) -> on
system: ext4

lvm-version is 2.02.74; cryptsetup 1.1.3;
mount options:
noatime,commit=60,barrier=1

currently the system is still running

@Tejun, Milan, Mike:
is there something like the following from reiser4 but for ext4 that
you could use to identify the problem:
--> debugfs.reiser4 -P <device> | bzip2 -c > <device>.bz2

I read about debugfs and catastrophic mode but I have no clue how that
should help

If you need any more info please tell, otherwise I'll wipe that system
and revert back to 2.6.36

I really hope that someone with the big boxes can reproduce this

unfortunately bisecting under these consequences would be impossible
for me (I need to study; waiting hours until the first corruption
occurs ...)

to make things easier:

the first kernel of the 2.6.37-line I compiled was before 2.6.37-rc1
got tagged and was shortly after btrfs got merged:

which should be around:
http://git.eu.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=67577927e8d7a1f4b09b4992df640eadc6aacb36

that should help cut time to narrow possible causes ...

Thanks ! && Regards

e.g. DM-mapth), anyway see:
https://www.redhat.com/archives/dm-devel/2010-November/msg00185.html

I'm not sure which patches you're using for the ext4 fsync changes but
please don't use them at all. It is purely an optimization for
extremely heavy fsync workloads and is only getting in the way at this
point.

We need better fault isolation; you've introduced enough change that it

tested he latest version of the dm-crypt cpu scalability patch quite a
bit and hasn't seen any corruption -- but clearly the corruption you're
seeing is a real concern and we need to get to the bottom of it.

I'd really appreciate it if you could just use Linus' latest linux-2.6
tree plus Milan's latest patch (technically v6 even though it wasn't
labeled as such): https://patchwork.kernel.org/patch/365542/

Porting that same v6 patch to 2.6.36 would also be nice (to verify you
still don't see any corruption there).

Hi Mike,

those other patches were for other problems I was seeing: e.g.
interactivity/latency problems I was experiencing during heavy
flushing, etc. and some more - so I speculated that those would
improve it


OK, enough of that additional stuff which distracts from this issue -
I'll leave them out for now ...

Thanks for the info !

To console you: I was using v5 from Milan's patch up until now and I
haven't noticed any corruption with it in conjunction with 2.6.36

drivers/md/dm-crypt.c:1408: error: WQ_MEM_RECLAIM' undeclared (first use in this function)

It should be enough to just replace WQ_MEM_RECLAIM to WQ_RESCUER for 2.6.36.

Milan
http://www.redhat.com/archives/dm-devel/2010-November/msg00099.html

and that worked fine

Thanks for pointing to v6 ! I hadn't noticed that there was a new one :)

Well, so I'll restore my box to a working/productive state and will
try out v6 (I'm pretty confident that it'll work without problems).

After that I'll see what info Tejun and the others need when the next
corruption might occur with vanilla 2.6.37-rc* and v6 so that there's
something to investigate

Thanks & Regards

It's the same as previous, just with fixed header (to track it properly
in patchwork) , second patch adds some read optimisation, nothing what
should help here.

Anyway, I run several tests on 2.6.37-rc3+ and see no integrity
problems (using xfs,ext3 and ext4 over dmcrypt).

So please try to check which change causes these problems for you,
it can be something completely unrelated to these patches.

(If if anyone know how to trigger some corruption with btrfs/dmcrypt,
let me know I am not able to reproduce it either.)

Perhaps this is useful: for myself, I found that when I started using
2.6.37rc3 that postgresql starting having a *lot* of problems with
corruption. Specifically, I noted zeroed pages, corruption in headers,
all sorts of stuff on /newly created/ tables, especially during index
creation. I had a fairly high hit rate of failure. I backed off to
2.6.34.7 and have *zero* problems (in fact, prior to 2.6.37rc3, I had
never had a corruption issue with postgresql). I ran on 2.6.36 for a
few weeks as well, without issue.

I am using kcrypt with lvm on top of that, and ext4 on top of that.

With unpatched dmcrypt (IOW with Linus' git)? Then it must be ext4 or
dm-core problem because there were no patches for dm-crypt...

Anyway, thanks for hint how to reproduce it.

Matt and Jon,

If you'd be up to it: could you try testing your dm-crypt+ext4
corruption reproducers against the following two 2.6.37-rc commits:

1) 1de3e3df917459422cb2aecac440febc8879d410
then
2) bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc

Then, depending on results of no corruption for those commits, bonus
points for testing the same commits but with Andi and Milan's latest
dm-crypt cpu scalability patch applied too:
https://patchwork.kernel.org/patch/365542/

Thanks!

1) 1de3e3df917459422cb2aecac440febc8879d410
then
2) bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc
Then, depending on results of no corruption for those commits, bonus
points for testing the same commits but with Andi and Milan's latest
https://patchwork.kernel.org/patch/365542/
Thanks!
Mike
Yeah sure,

I'll have to set up another testing system (on a separate partition /
volume group) for its own so that will take some time,
first tests will be run probably in the weekend,

thanks for those pointers !

I took a look at git-web - you think
5a87b7a5da250c9be6d757758425dfeaf8ed3179 might be relevant, too ?

the others seem rather minor compared to those you posted

Afaik last time I run vanilla 2.6.37-rc* (which was probably around
rc1) I saw no corruption at all but I'll give it a test-run without
the dm-crypt patch anyway

Thanks & Regards

Matt

Perhaps this is useful: for myself, I found that when I started using
2.6.37rc3 that postgresql starting having a *lot* of problems with
corruption. Specifically, I noted zeroed pages, corruption in headers,
all sorts of stuff on /newly created/ tables, especially during index
creation. I had a fairly high hit rate of failure. I backed off to
2.6.34.7 and have *zero* problems (in fact, prior to 2.6.37rc3, I had
never had a corruption issue with postgresql). I ran on 2.6.36 for a
few weeks as well, without issue.
I am using kcrypt with lvm on top of that, and ext4 on top of that.
With unpatched dmcrypt (IOW with Linus' git)? Then it must be ext4 or
dm-core problem because there were no patches for dm-crypt...

Hi Mike,

it seems like there isn't even much testing to do:

I tested all 3 commits / checkouts by re-compiling gcc which was/is
the 2nd easy way to trigger this "corruption", compiling google's
chromium (v9) and looking at the output/existance of gcc, g++ and
eselect opengl list

so far everything went fine

After that I used the new patch (v6 or pre-v6), before that I had to

replace WQ_MEM_RECLAIM with WQ_RESCUER

and, re-compiled the kernels

shortly after I had booted up the system with the first kernel
(http://git.eu.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5a87b7a5da250c9be6d757758425dfeaf8ed3179)
the output of 'eselect opengl list' did show no opengl backend
selected

so it seems to manifest itself even earlier (ext4: call
mpage_da_submit_io() from mpage_da_map_blocks()) even if only subtly
and over time -
I'm still currently running that kernel and posting from it & having tests run

I'm not sure if it's even a problem with ext4 - I haven't had the time
to test with XFS yet - maybe it's also happening with that so it more
likely would be dm-core, like Milan suspected
(http://marc.info/?l=linux-kernel&m=129123636223477&w=2) :(

@Jon,

you had time to do some tests meanwhile ? what did you find out ?

even though most of the time it's compiling I don't need to do much -
I need the box for work so if my time allows next tests would be next
weekend and I'm back to my other partition

I really do hope that this bugger can be nailed down ASAP - I like the
improvements made in 2.6.37 but without the dm-crypt multi-cpu patch
it's only half the "fun" ;)

Thanks & Regards

Matt

Can you be a bit more precise about what you're doing to reproduce?
What sequence? What (if any) builds are going in parallel? Etc.

It'd be interesting to try to reproduce with that same kernel but using
XFS. I'll check with Milan on what he thinks would be the best next
steps. Ideally we'll be able to reproduce your results to aid in
pinpointing the issue. I think Milan will be trying to do so shortly
(if he hasn't started already -- using gentoo emerge, etc).

Sure, we'll need to get to the bottom of this before we can have
confidence sending the dm-crypt cpu scalability patch upstream.

Thanks for your testing,

chromium (v9) and looking at the output/existance of gcc, g++ and
eselect opengl list
Can you be a bit more precise about what you're doing to reproduce?
What sequence?  What (if any) builds are going in parallel?  Etc.
sure:

running on a core i7 860,
~amd64, with MAKEOPTS="-j9", -march=native -pipe

parallel-build or other features are not enabled so it's always only
one program serial running/compiling

emerge -1 sys-devel/gcc -v
in the past after that the output of
eselect opengl list

with a very high probability would be corrupted (the descriptions at
the top NOT but the (dynamic) paths to the opengl files) - I'm running
fglrx/catalyst from AMD so (unfortunately) it's a tainted kernel with
a Radeon HD 5850 (I'm currently having problems to get the evergreen
xf86-video-ati driver to run so I use fglrx)
so it would display

eselect opengl list
Available OpenGL implementations:
[1] ati
[2] xorg-x11

instead of

eselect opengl list
Available OpenGL implementations:
[1] ati *
[2] xorg-x11

(mark the *)

and

instead of

cat /etc/env.d/03opengl
# Configuration file for eselect
# This file has been automatically generated.
LDPATH="//usr/lib32/opengl/ati/lib://usr/lib64/opengl/ati/lib"
OPENGL_PROFILE="ati"

it would be

cat /etc/env.d/03opengl
# Configuration file for eselect
# This file has been automatically generated.
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@@@@@@@@@@@@@@

or something similar nonsensical


other things I did/tested for after every 10-50 packages got emerged:

gcc-config -l
<-- check whether output is correct and (still) properly set

eselect opengl list
<-- check whether output is correct and (still) properly set

gcc -v

ldd

g++

(those files or files having to do with them got corrupted with a
higher probability in the past)

also programs such as firefox and chromium, gedit, etc. would have
missing libraries and/or didn't run anymore or would hang (having a Dl
or D in htop - I don't know what Dl means)

the environment I was in was vtwm, twm or sometimes even gnome running
from the root-account (to test stuff)

kernel compiled was from sources checked out at
1de3e3df917459422cb2aecac440febc8879d410

after that I counter-checked logs and couldn't find anything similar
for 5a87b7a5da250c9be6d757758425dfeaf8ed3179 (that checkout/commit
seemingly worked fine besides the
little "anomaly" of the empty/not set /etc/env.d/03opengl - I didn't
observe anything else broken on that one)

seems 1de3e3df917459422cb2aecac440febc8879d410 might be a possible
candidate ... (strangely I didn't observe any corruption with that -
everything seemed to still be there except the BUG entry in dmesg and
the not anymore working system [apps not wanting to close or open,
hardlocks -> pointing to a filesystem issue which I already had
experienced in a similar way with other filesystems in the past] -
maybe bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc leads to corruption, I
don't know ?)

I ASAP saved the output to my /boot partition (reiserfs) and wanted to
send you a mail but firefox didn't work anymore correctly at that time
- so I wanted to close and restart it (at that time I was running
vtwm),
firefox (via gksu) like above mentioned it showed D or Dl from htop
and couldn't be closed - also not via killall -9

chromium and other apps also stopped to work (I couldn't launch them
anymore, also not via root-account/xterm),

as a last resort I wanted to close the (launched via gksu) running
terminal and open up another one via gksu -> terminal (selecting a
user-account)

shortly after that the box hardlocked (even magic SYSRQ key didn't
work anymore, numlock and caps lock also didn't work - I'm using a
usb-keyboard, perhaps a PS/2 keyboard would have helped but the PS/2
port of my system doesn't work that well/at all under linux and
windows [a bios problem]

summary/reference:
activities: regular stuff - such as browsing the web, hearing to mp3
files, streaming webradio, etc.

system activies: emerge sys-devel/gcc -1 && emerge -e system

testing/checking: gcc -v; ldd; g++; gcc-config -l; eselect opengl
list; cat /etc/env.d/03opengl

mount-options: noatime,commit=600 [now]; during previous tests/usage:
noatime,nodiratime,barrier=1,commit=600

i/o scheduler: CFQ (I have deadline set at boot because that one works
more reliable in case something's broken with CFS; after boot has
completed I manually switch to CFQ)

kernel: using the mentioned kernels compiled with genkernel (for
support with lvm and luks/cryptsetup)

compile via: genkernel --makeopts="-j16" --luks --dmraid --lvm all
--kernname=37_rc-checkout-name --no-clean

(sys-kernel/genkernel version is: genkernel-3.4.10.907-r3.ebuild [from
sabayon-overlay]; there shouldn't be much difference to the one in the
portage-tree: 3.4.10.907-r1)

partitioning: cryptsetup (around 30 GiB partition) [e.g. MAIN] ->
pvcreate /dev/mapper/MAIN
vgcreate GENTOO /dev/mapper/MAIN
lvcreate -L9200M -nSWAP GENTOO
lvcreate -l100%FREE -nROOT GENTOO

so cryptsetup -> LVM -> ROOT (20 GiB) and SWAP (around 9200 MiB) -> on
ROOT (ext4)

filesystem: mkfs.ext4 (default settings; other settings didn't make a
change if the corruption/problems occured or not)

I'm not sure if it's even a problem with ext4 - I haven't had the time
to test with XFS yet - maybe it's also happening with that so it more
likely would be dm-core, like Milan suspected
(http://marc.info/?l=linux-kernel&m=129123636223477&w=2) :(
It'd be interesting to try to reproduce with that same kernel but using
XFS.  I'll check with Milan on what he thinks would be the best next
steps.  Ideally we'll be able to reproduce your results to aid in
pinpointing the issue.  I think Milan will be trying to do so shortly
(if he hasn't started already -- using gentoo emerge, etc).

even though most of the time it's compiling I don't need to do much -
I need the box for work so if my time allows next tests would be next
weekend and I'm back to my other partition
I really do hope that this bugger can be nailed down ASAP - I like the
improvements made in 2.6.37 but without the dm-crypt multi-cpu patch
it's only half the "fun" ;)
Sure, we'll need to get to the bottom of this before we can have
confidence sending the dm-crypt cpu scalability patch upstream.
Thanks for your testing,
Mike
Sure, you're welcome - I'm glad that I can help

Below attached/posted you'll find the full output of dmesg for that
session and my kernel-config (attaching file strangely doesn't seem to
work right now)

So that should be enough information to (hopefully) reproduce it or at
least fix underlying causes to prevent it in the future

Thanks & Regards

Matt

OK.
after some time of running (around 1 to 1.5 hours) I noticed the
[ 4421.503477] ------------[ cut here ]------------
[ 4421.503482] kernel BUG at fs/ext4/inode.c:2714!
kernel compiled was from sources checked out at
1de3e3df917459422cb2aecac440febc8879d410
Looking at 1de3e3df917459422cb2aecac440febc8879d410:

Line 2714 in fs/ext4/inode.c is this:

/*
* If the page does not have buffers (for whatever reason),
* try to create them using block_prepare_write. If this
* fails, redirty the page and move on.
*/
if (!page_buffers(page)) {
^^^^^^^^^^^^^^^^^^^^^^^^^^^
if (block_prepare_write(page, 0, len,
noalloc_get_block_write)) {
redirty_page:
redirty_page_for_writepage(wbc, page);
unlock_page(page);
return 0;
}
commit_write = 1;
}

Which means we're really hitting this:

/* If we *know* page->private refers to buffer_heads */
#define page_buffers(page) \
({ \
BUG_ON(!PagePrivate(page)); \
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
((struct buffer_head *)page_private(page)); \
})
#define page_has_buffers(page) PagePrivate(page)

Looks like Ted fixed it here:

commit b1142e8fec6a594723e5054055a7b53379b90490
Author: Theodore Ts'o <***@mit.edu>
Date: Thu Oct 28 17:33:57 2010 -0400

ext4: BUG_ON fix: check if page has buffers before calling page_buffers()


Basically, once you hit this oops, ext4 is done. No files you created
after the oops will be there when you reboot, and the rest of your
lockups etc are because the jbd process had some locks held when it
crashed.

Was there also a report of corruption w/dm-crypt and XFS?

Last night I ran dm-crypt + the cpu scalability patch + ext4 +
2.6.37-rc3 in a long stress, and it passed without any problems. If
dm-crypt were not doing the IO properly, this test probably would have
found it (+/- strange block sizes, races with O_DIRECT and other exotic
fun).

I finally found some time to test this out. With 2.6.37-rc4 (openSUSE
KOTD kernel) I easily encounter the issue.

Using a virtual machine, I created a stock, minimal openSUSE 11.3 x86_64
install, installed all updates, installed postgresql and the 'KOTD'
(Kernel of the Day)
kernel, and ran the following tests (as postgres user because I'm
lazy).

1. create a database (from bash):

createdb test

2. place the following contents in a file (I used 't.sql'):

begin;
create temporary table foo as select x as a, ARRAY[x] as b FROM
generate_series(1, 10000000 ) AS x;
create index foo_a_idx on foo (a);
create index foo_b_idx on foo USING GIN (b);
rollback;

3. execute that sql:

psql -f t.sql --echo-all test


With 2.6.34.7 I can re-run [3] all day long, as many times as I want,
without issue.

With 2.6.37-rc4-13 (the currently-installed KOTD kernel) if tails
pretty frequently.

Then I tested with the 'vanilla' kernel available here:

http://download.opensuse.org/repositories/Kernel:/vanilla/standard/

The 'vanilla' kernel exhibited the same problems.
The version I tested: 2.6.37-rc4-219-g771f8bc-vanilla.

Incidentally, quick tests of jfs, xfs, and ext3 do _not_ show the same
problems, although I will note that I usually saw failure at least 1
in 3, but sometimes had to re-run the sql test 4 or 5 times before I
saw failure.

I will continue to do some testing, but I will hold off on testing the
commits above until I receive further testing suggestions.

OK, so to be clear: your testing is on dm-crypt + ext4?

And you're testing upstream based kernels (meaning the dm-crypt
scalability patch that has been in question is _not_ in the mix)?

That is a very different report than the other 2 reports of corruption
(those corruption instances were only seen once the dm-crypt scalability
patch was introduced).

postgresql errors. Typically, header corruption but from the limited
visibility I've had into this via strace, what I see is zeroed pages
where there shouldn't be.

I just ran a test and got:

ERROR: invalid page header in block 37483 of relation base/16384/16417

but that is not the only error one might get.

Yes. I took a virtual hard disk which shows up as /dev/sdb, used
cryptsetup to format it as a LUKS volume, mounted the LUKS volume,
formatted as ext4 (or whatever), mounted that, rsync'd over a blank
postgresql 'data' directory, started postgresql, became the postgres
user, and proceeded to create the db and run the sql.
And you're testing upstream based kernels (meaning the dm-crypt
scalability patch that has been in question is _not_ in the mix)?
I am testing both the KOTD kernels and the "vanilla" kernels - neither
of which has the dm-crypt patches (as far as I know).

This sounds a lot like a bug higher up than dm-crypt. Zeros tend to
come from some piece of code explicitly filling a page with zeros, and
that often happens in the corner cases for O_DIRECT and a few other
places in the filesystem.

Have you tried triggering this with a regular block device?

I just tried the whole set of tests, but with /dev/sdb directly (as
ext4) without any crypt-y bits.
It takes more iterations but out of 6 tests I had one failure: same
type of thing, 'invalid page header in block ....'.

I can't guarantee that it is a full-page of zeroes, just what I saw
from the (limited) stracing I did.

Fantastic. Now for our usual suspects:

1) Is postgres using O_DIRECT? If yes, please turn it off
2) Is postgres allocating sparse files? If yes, please have it fully
allocate the file instead.
3) Is postgres using preallocation (fallocate)? If yes, please have it
fully allocate the file instead

That's a tough one. I don't think postgresql does that, but I'm not an

As far as strace is concerned, postgreql is not using fallocate in

Well, the only other usual suspect would be mmap.  Does the strace show

on the files?
I'm pretty sure postgresql uses regular file I/O and not mmap.

Because this is all done in a transaction (which fails), and because
the table is a TEMPORARY table, there *are* no files once the
transaction fails because postgresql unlinks them.

I can modify the test to use real tables and do things outside of a
transaction, however.

I was using fdatasync[1] and now I'm using sync. I'm on 9 iterations
without a failure (on ext4 - no crypt). Theoretically, these settings
only make a difference in the event of a crash. However, could they
make a difference in terms of the paths taken in the kernel?

Yes, the paths are different but similar. If ext4 is causing zeros to
get stuffed somewhere, it should happen for both O_SYNC and fdatasync.

postgresql errors. Typically, header corruption but from the limited
visibility I've had into this via strace, what I see is zeroed pages
where there shouldn't be.
This sounds a lot like a bug higher up than dm-crypt.  Zeros tend to
come from some piece of code explicitly filling a page with zeros, and
that often happens in the corner cases for O_DIRECT and a few other
places in the filesystem.
Have you tried triggering this with a regular block device?
I just tried the whole set of tests, but with /dev/sdb directly (as
ext4) without any crypt-y bits.
It takes more iterations but out of 6 tests I had one failure: same
type of thing, 'invalid page header in block ....'.
I can't guarantee that it is a full-page of zeroes, just what I saw
from the (limited) stracing I did.
Maybe not so fantastic. I kept testing and had no more failures. At
all. After 40+ iterations I gave up.
I went back to trying ext4 on a LUKS volume. The 'hit' ratio went to
something like 1 in 3, or better.

I will continue to do testing with and without LUKS. I did /not/
reboot between tests, but I do start with a fresh postgres database.

Encryption usually propagates bit corruption (not sure if it is
in this case). But in principle if there is one bit corrupted,
after decryption the whole sector is corrupted.
(That's why bit media errors have usually more serious impact
with FDE.)

Isn't there random noise instead of zeroes when reading
sparse files?
We should probably write some test focusing on sparse files
handling here...

Once we trigger once without dm-crypt, dm-crypt is off the hook. Just
to verify, when you say without luks, you mean without any crypto bits
in use at all on the filesystems postgres uses?

Usually the trick to reproducing filesystem corruptions is adding memory
pressure. The corruption is probably a bad interaction between reads
and writes, and we need to make sure the reads actually happen.

http://oss.oracle.com/~mason/pin_ram.c

gcc -Wall -o pin_ram pin_ram.c

pin_ram -m 80%-of-your-ram-in-mb

The idea is to trigger constant reads without having to swap heavily.
80% might be too much.

1) Is postgres using O_DIRECT?  If yes, please turn it off
According to strace, O_DIRECT didn't show up once during the test.
2) Is postgres allocating sparse files?  If yes, please have it fully
allocate the file instead.
That's a tough one. I don't think postgresql does that, but I'm not an
expert here.
Ok, please compare du -k and du -k --apparent-size for each of the
files involved in the postgres run.
One of the files (the table itself) is very slightly sparse:
588240 (apparent) vs 588244

With 2.6.34.7 I can re-run [3] all day long, as many times as I want,
without issue.
With 2.6.37-rc4-13 (the currently-installed KOTD kernel) if tails
pretty frequently.
So I just tried to reproduce this on an Ubuntu 10.04 system running
2.6.37-rc5 (completely stock except for a few apparmor patches that I
needed to keep the apparmor userspace from complaining). I'm using
Postgres 8.4.5-0ubuntu10.04.

Using the above procedure, I wasn't able to reproduce. Then I
realized this might have been because I was using an SSD root file
system (which is secured using LUKS/dm-crypt, with LVM on top of
dm-crypt). So I mounted a file system on a 5400 rpm SSD disk, which
is also protected using LUKS/dm-crypt with LVM on top. I then
executed the PostgresQL commands:

CREATE TABLESPACE test LOCATION '/kbuild/postgres';
SET default_tablespace = test;
COMMIT
\quit

I then re-ran the above proceduing, and verified that all of the I/O
was going to the 5400rpm laptop disk.

I then ran the above procedure a half-dozen times, and I still haven't
been able to reproduce any Postgresql errors or kernel errors.

Jon, can you help me identify what might be different with your run
and mine? What version of Postgres are you using?

Thanks,

- Ted

I am using postgres 8.4.5 on openSUSE 11.3 x86_64.
The problems were observed on both "real" hardware (thinkpad T61p) and
in virtualbox, where all current testing is taking place. The current
kernel is a "vanilla" (unpatched) kernel. I *did* set wal_sync_method
to fdatasync, however, if that is relevant. Otherwise, the pg config
is stock. With no crypt involved, I did have to iterate the tests to
observe the issue - a half-dozen times or more were necessary.
Typically, when crypt was involved, the issue would manifest much more
rapidly.

One difference is the location of the transaction logs (pg_xlog). In
my case, /var/lib/pgsql/data *is* mountpoint for the test volume
(actually, it's a symlink to the mount point). In your case, that is
not so. Perhaps that makes a difference? pgsql_tmp might also be on
two different volumes in your case (I can't be sure).

I grabbed a Kubuntu iso and installed Kubuntu 10.10, and then upgraded
to 'natty', and eventually to 2.6.37-8-generic.

With that install, and postgresql's "data" (/var/lib/postgresql/data)
being located on a LUKS+ext4 volume, I easily observe the behavior.

Does this help?

If you can point out how to query pgsql_tmp (I'm using a completely
default postgres install), that would be helpful, but I don't think it
would be going anywhere else.

Still trying....

You should be OK, there. Are you using encryption or no?
I had difficulty replicating the issue without encryption.

Normally it's /var/lib/pgsql/data/pgsql_tmp (or
/var/lib/postgres/data/pgsql_tmp in your case). By placing
/var/lib/{postgresql,pgsql}/data on the LUKS + ext4 volume, on both
openSUSE 11.3 and Kubuntu, I was able to replicate the problem easily,
in VirtualBox. I can give qemu a try. In both cases I was using a

Ah, I'm not using virtualization. I'm running on a X410 laptop, on
raw hardware. Perhaps virtualization slows things down enough that it
triggers? Or maybe you're running with a more constrained memory than
I? How much memory do you have configured in your VM?

512MB.
'free' reports 75MB, 419MB free.
I originally noticed the problem on really real hardware (thinkpad
T61p), however.
If you can easily reproduce it could you try a git bisect?
Do we have a known good kernel?  I looked back through the thread and
didn't see any reports where the postgres test on ext4 passed in this
config.
2.6.34.something.  -- Any chance a newer kernel can be tested to be found good?
But he is triggering the ext4 corruption without dm-crypt.  I think
dm-crypt was still used somewhere on the system during the test, just
not on the partitions that actually hit the corruption.
I now have my doubts about being able to trigger it without dm-crypt.
I stand by my report, but I'm also unable to reproduce it after after
50 test iterations. I did run 2.6.36 for a few weeks without any issue
that I recall.

Try a kernel before 5a87b7a5da250c9be6d757758425dfeaf8ed3179

from the tests I've done that one showed the least or no corruption if
you count the empty /etc/env.d/03opengl as an artefact

(I tested 3 commits in total)


1) 5a87b7a5da250c9be6d757758425dfeaf8ed3179

2) 1de3e3df917459422cb2aecac440febc8879d410

3) bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc

1 -> 3 (earlier -> later)

Yes, that's a good test. Also try commit bd2d0210cf. The patch
series that is most likely to be at fault if there is a regression in
between 5a87b7a5d and bd2d0210cf inclusive.

I did a lot of testing before submitting it, but that wa a tricky
rewrite. If you can reproduce the problem reliably, it might be good
to try commit 16828088f9 (the commit before 5a87b7a5d) and commit
bd2d0210cf. If it reliably reproduces on bd2d0210cf, but is clean on
16828088f9, then it's my ext4 block i/o submission patches, and we'll
need to either figure out what's going on or back out that set of
changes.

If that's the case, a bisect of those changes (it's only 6 commits, so
it shouldn't take long) would be most appreciated.

Regards,

- Ted

- For me, triggering the problem is fairly easy when encryption is involved.
- I'm now 81 iterations into testing
bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc *without* encryption. Out of
81 iterations, I have 4 failures: #16, 40, 62, and 64.

I will now try 1de3e3df917459422cb2aecac440febc8879d410 much more extensively.

Is this useful information?

Yes, indeed. Is this in the virtualized environment or on real
hardware at this point? And how many CPU's do you have configured in
your virtualized environment, and how memory memory? Is having a
certain number of CPU's critical for reproducing the problem? Is
constricting the amount of memory important?

It'll be a lot easier if I can reproduce it locally, which is why I'm
asking all of these questions.

Thanks,

One experiment --- can you try this with the file system mounted with
data=writeback, and see if the problem reproduces in that journalling
mode?

I want to rule out (if possible) journal_submit_inode_data_buffers()
racing with mpage_da_submit_io(). I don't think that's the issue, but
I'd prefer to do the experiment to make sure. So if you can use a
kernel and system configuration which triggers the problem, and then
try changing the mount options to include data=writeback, and then
rerun the test, and let me know if the problem still reproduces, I'd
be really grateful.

Thanks,

Originally, I observed the behavior on really real hardware.

Since then, I have been able to reproduce it in VirtualBox and
qemu-kvm, with openSUSE 11.3 and KUbuntu. All of the more recent tests
have been with qemu-kvm.

I have one CPU configured in the environment, 512MB of memory.
I have not done any memory-constriction tests whatsoever.

That test is running now, first with encryption. I will report if it
shows problems. If it does, I will wait until I have been able to see
that a few times, and move to a no-encryption test. Typically, I have
to run quite a few more iterations of that test before problems show
up (if they will at all).

I have not done any memory-constriction tests whatsoever.
I've finally been able to reproduce it myself, on real hardware. SMP
is not necessary to reproduce it, although having more than one CPU
doesn't hurt. What I did need to do (on real hardware with 4 gigs of
memory) was to turn off swap and pin enough memory so that free memory
was around 200megs or so before the start of the test. (This is the
natural amount of free memory that the system would try to reach,
since 200 megs is about 5% of 4 gigs.)

Then, during the test, free memory would drop to 50-70 megabytes,
forcing writeback to run, and then I could trigger it about 1-2 times
out of three.

I'm guessing that when you used 512mb of memory, that was in effect a
memory-constriction test, and if you were to push the memory down a
little further, it might reproduce even more quickly. My next step is
to try to reproduce this in a VM, and then I can start probing to see
what might be going on.

This patch seems to fix the problem for me. (Unless the partition is
mounted with mblk_io_submit.)

Could you confirm that it fixes it for you as well?

commit a8649d85bd0ab3be6014918bd9eae319a0ffc691
Author: Theodore Ts'o <***@mit.edu>
Date: Sun Dec 12 20:57:19 2010 -0500

ext4: Turn off multiple page-io submission by default

Jon Nelson has found a test case which causes postgresql to fail with
the error:

psql:t.sql:4: ERROR: invalid page header in block 38269 of relation base/16384/16581

Under memory pressure, it looks like part of a file can end up getting
replaced by zero's. Until we can figure out the cause, we'll roll
back the change and use block_write_full_page() instead of
ext4_bio_write_page(). The new, more efficient writing function can
be used via the mount option mblk_io_submit, so we can test and fix
the new page I/O code.

To reproduce the problem, install postgres 8.4 or 9.0, and pin enough
memory such that the system just at the end of triggering writeback
before running the following sql script:

begin;
create temporary table foo as select x as a, ARRAY[x] as b FROM
generate_series(1, 10000000 ) AS x;
create index foo_a_idx on foo (a);
create index foo_b_idx on foo USING GIN (b);
rollback;

If the temporary table is created on a hard drive partition which is
encrypted using dm_crypt, then under memory pressure, approximately
30-40% of the time, pgsql will issue the above failure.

This patch should fix this problem, and the problem will come back if
the file system is mounted with the mblk_io_submit mount option.

I'm glad you've been able to reproduce the problem! If you should need
any further assistance, please do not hesitate to ask.
This patch seems to fix the problem for me.  (Unless the partition is
mounted with mblk_io_submit.)
Could you confirm that it fixes it for you as well?
I believe I have applied the (relevant) inode.c changes to
bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc, rebuilt and begun testing.
Now at 28 passes without error, I think I can say that the patch
appears to resolve the issue.

Confirmed !

I'm running my box for 5+ hours right now with your patch applied in
addition to Andi's/Milan's patch
(http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-crypt-scale-to-multiple-CPUs.patch)
, Ted, and can't see any indications of corruptions so far (while
doing an emerge -e system) and doing everyday stuff.
My /home partition (with ext4) is also still intact [which of course
has a backup] so it seems to fix it for me, too

so the corruption I was seeing was similar in a way to that of Jon

I have a question though: the deactivation of multiple page-io
submission support most likely only would affect bigger systems or
also desktop systems (like mine) ?

I think this is not a final fix, just a workaround.
The problem with the other path still really needs to be tracked down.

Matt and Jon,
If you'd be up to it: could you try testing your dm-crypt+ext4
1) 1de3e3df917459422cb2aecac440febc8879d410
then
2) bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc
Then, depending on results of no corruption for those commits, bonus
points for testing the same commits but with Andi and Milan's latest
https://patchwork.kernel.org/patch/365542/
Thanks!
Mike
Hi Mike,
I tested all 3 commits / checkouts by re-compiling gcc which was/is
the 2nd easy way to trigger this "corruption", compiling google's
chromium (v9) and looking at the output/existance of gcc, g++ and
eselect opengl list
Can you be a bit more precise about what you're doing to reproduce?
What sequence?  What (if any) builds are going in parallel?  Etc.
Post by Matt
so far everything went fine
After that I used the new patch (v6 or pre-v6), before that I had to
replace WQ_MEM_RECLAIM with WQ_RESCUER
and, re-compiled the kernels
shortly after I had booted up the system with the first kernel
(http://git.eu.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5a87b7a5da250c9be6d757758425dfeaf8ed3179)
the output of 'eselect opengl list' did show no opengl backend
selected
so it seems to manifest itself even earlier (ext4: call
mpage_da_submit_io() from mpage_da_map_blocks()) even if only subtly
and over time -
I'm still currently running that kernel and posting from it & having tests run
OK.
Post by Matt
I'm not sure if it's even a problem with ext4 - I haven't had the time
to test with XFS yet - maybe it's also happening with that so it more
likely would be dm-core, like Milan suspected
(http://marc.info/?l=linux-kernel&m=129123636223477&w=2) :(
It'd be interesting to try to reproduce with that same kernel but using
XFS.  I'll check with Milan on what he thinks would be the best next
steps.  Ideally we'll be able to reproduce your results to aid in
pinpointing the issue.  I think Milan will be trying to do so shortly
(if he hasn't started already -- using gentoo emerge, etc).
Post by Matt
even though most of the time it's compiling I don't need to do much -
I need the box for work so if my time allows next tests would be next
weekend and I'm back to my other partition
I really do hope that this bugger can be nailed down ASAP - I like the
improvements made in 2.6.37 but without the dm-crypt multi-cpu patch
it's only half the "fun" ;)
Sure, we'll need to get to the bottom of this before we can have
confidence sending the dm-crypt cpu scalability patch upstream.
Thanks for your testing,
Mike
I should have made it clear that the results I get are observed when
using the kernels/checkouts *with* the dm-crypt multi-cpu patch,
without the patch I didn't see that kind of problems (hardlocks, files
missing, etc.)

I have to take back my other two emails, stating that no corruption
happened with the dm-crypt multi-cpu patch. Today, I encountered
filesystem corruption on one, and a complete hardlock on another machine.
No logfile entries, no m-sysrq, a complete deadlock. Filesystem was
corrupted here too, had to reboot from CD.

The machines with plain 2.6.37-rc4 are up and running...

Which kernel? 2.6.37-rc?

Anyone seen this with 2.6.36 and the same dmcrypt patch?
(All info I had is that is is stable with here.)

It still seems to like dmcrypt with its parallel processing is just
trigger to another bug in 37-rc.

Both 2.6.36 and 2.6.36.1 with your patch have been running flawlessly.
Not a single problem at all, over several weeks. 24/7.

I've been using a kernel which is between 2.6.37-rc2 and -rc3 with a LUKS / dm-crypt / LVM / ext4 setup for my primary file systems, and I haven't observed any corruption for the last two weeks or so. It's on my todo list to upgrade to top of Linus's tree, but perhaps this is a useful data point.

As another thought, what version of GCC are people using who are having difficulty? Could this perhaps be a compiler-related issue?

in my case it also has the --enable-esp functionality [hardened]

and for linking/ldd: -Wl,-z,now -Wl,-z,relro

(I don't know if the part with the linker and the fstack-protector is accurate)

I'm adding below the output of mount of the system-partition of the
system I was running the kernel on - where the [more observable]
corruption was observed (checkout
bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc)
-> this output got generated while I mounted it from my working (no
corruption observed) system with 2.6.36 kernel - I don't know if it's
useful - just in case you might need it

gcc version 4.5.1 (Gentoo Hardened 4.5.1-r1 p1.4, pie-0.4.5)
This is probably just me being paranoid, but it might be worth trying
using a gcc 4.4.x compiler and see if that makes any difference.
There have been some other gcc 4.5-caused probablems with the kernel,
and it might be a good idea to rule those out. (I'm using gcc 4.4.3,
myself, and I'm deliberately avoiding the use of gcc 4.5 for now.)

A bit late to the party, but does memtest86 pass over multiple iterations?

Also, can you send an 'sudo lspci -vv', so we can check for
known-buggy controllers and bridges?

Thanks,

Yes, it does. This machine had not a single fault in several years, it's
absolutely rock-stable. These freezes/corruptions are the first ones ever,
and they vanish when I go down to 2.6.36 or revert the latest dm-crypt
multi-cpu patch with 2.6.37-rc.

I've been using a kernel which is between 2.6.37-rc2 and -rc3 with a LUKS / dm-crypt / LVM / ext4 setup for my primary file systems, and I haven't observed any corruption for the last two weeks or so. It's on my todo list to upgrade to top of Linus's tree, but perhaps this is a useful data point.
The reported corruptions are with a .37 forward port someone did of my parallel
kcryptd patch. The 2.6.36 (and earlier) versions are rock solid with many users.

The classic dmcrypt is single threaded and very slow.

A compiler problem seems very unlikely here.

What may be an useful experiment would be to test 2.6.37-rc + ext4 over
device mapper, but not dmcrypt. If that fails too then it's likely
some generic device mapper problem.

That would only prove its not dm-crypt; it would not absolve a non-DM
2.6.37-rc change at all.

Leveraging the fact that 2.6.36 + parallel dm-crypt is reportedly very
solid: maybe these would be more interesting (each would keep the latest
parallel dm-crypt patch overlayed for all tests):

1) Test 2.6.37-rc prior to all flush+fua changes (only changes DM saw
for 2.6.37-rc so far).

2) Back out all ext4 changes that were merged for 2.6.37-rc
- though Heinz is using XFS exclussively and still reported
corruption

3) A full git bisect of good=v2.6.36 bad=v2.6.37-rc4 would be the most
interesting. Albeit much more tedious.

ok, to not confuse which patch version people are testing,
let's use the version in Alasdair's DM repo now (upstream queue):
http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-crypt-scale-to-multiple-CPUs.patch
(it should be the same as v5/v6 here on dm-devel -
Andi's patch + my changes for device stacking deadlock)

The same patch (just with minor define fix) is reported rock solid for 2.6.36.

Pretty much exactly the same setup here (LUKS/dm-crypt/LVM/ext4), pretty
consistently running most-recent mmotm kernel, which tends to be somewhat ahead
of linux-next, and I haven't seen anything either. (I admit I haven't tried
-rc4-mmotm1202 yet).

It still seems to like dmcrypt with its parallel processing is just
trigger to another bug in 37-rc.
To come back to this: my 3 systems (XFS filesystem) running the latest
dm-crypt-scale-to-multiple-cpus patch from Andi Kleen/Milan Broz have
not showed a single problem since 2.6.37-rc6 and above. No corruption any
longer, no freezes, nothing. The patch applies cleanly to 2.6.37, too,
and runs just fine.

I blindly guess that my data corruption problem was related to something else in the
2.6.37-rc series up to -rc4/5.

Since this patch is a significant improvement: any chance that it finally gets
merged into mainline/stable?

Hi Heinz,

I've been using this patch since 2.6.37-rc6+ with ext4 and xfs
filesystems and haven't seen any corruptions since then
(ext4 got "fixed" since 2.6.37-rc6, xfs showed no problems from the start)

http://git.eu.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=1449032be17abb69116dbc393f67ceb8bd034f92
(is the actual temporary fix for ext4)

Regards

Matt

using the kernels/checkouts *with* the dm-crypt multi-cpu patch,
without the patch I didn't see that kind of problems (hardlocks, files
missing, etc.)
I have to take back my other two emails, stating that no corruption
happened with the dm-crypt multi-cpu patch. Today, I encountered
filesystem corruption on one, and a complete hardlock on another machine.
No logfile entries, no m-sysrq, a complete deadlock. Filesystem was
corrupted here too, had to reboot from CD.
The machines with plain 2.6.37-rc4 are up and running...
Hi Heinz,

that's bad news :(
hopefully you had a backup available


to complete my last report with the corruption/empty file for
/var/db/pkg/sys-devel/patch-2.6.1/COUNTER

(kernel running was from commit bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc)

I got more and more corruption and the following BUG message in dmesg:

then I continued some browsing on the web (reading stuff & research)
and letting music (mp3) run

rekonq was fired up, for some minutes it worked, and then it hang
and/or slowed down during loading of websites - it eventually finished
it couldn't really be closed - only via killlall
and it remained in D (daemon ?) state in htop

ps aux | grep rekonq showed:
[rekonq] <defunct>

addr2line didn't reveal much useful - only: inode.c:0

shortly before I wanted to shutdown my box I to tried to sync stuff to
post some info (if you guys need it) but syncing wouldn't work anymore

time sync && sdparm -C sync /dev/sdd

the Magic SYSRQ key still (half-way) worked: closing apps, etc. was
possible but syncing also didn't work anymore

so I did a Alt + Print + REI UO


short summary what happened:

the kernel running is from checkout/commit:
bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc
1) emerge -1 sys-devel/gcc
COUNTER file in /var/db/pkg/sys-devel/patch-2.6.1/ got corrupted/empty
2) config files of eselect mesa got corrupted
3) rekonq would hang/slow down for several moments while loading
websites - it would continue loading them eventually but further usage
wasn't possible anymore

4) somewhere between 1 and 3 the BUG message appeared in dmesg
5) syncing wouldn't work anymore

*) often un- and re-mounting is my /boot-partition
*) my portage-tree is on the XFS-partition with delayed logging
*) the other ext4-partition (dm-3) is my /home-partition mounted ro (read-only)

Seems like it's really some issues with ext4 ...

Below you'll find the output of dmesg for the full session

Thanks & Regards

Matt

Matt and Jon,
If you'd be up to it: could you try testing your dm-crypt+ext4
1) 1de3e3df917459422cb2aecac440febc8879d410
then
2) bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc
Then, depending on results of no corruption for those commits, bonus
points for testing the same commits but with Andi and Milan's latest
https://patchwork.kernel.org/patch/365542/
Thanks!
Mike
Hi Mike,
I tested all 3 commits / checkouts by re-compiling gcc which was/is
the 2nd easy way to trigger this "corruption", compiling google's
chromium (v9) and looking at the output/existance of gcc, g++ and
eselect opengl list
Can you be a bit more precise about what you're doing to reproduce?
What sequence?  What (if any) builds are going in parallel?  Etc.
Post by Matt
so far everything went fine
After that I used the new patch (v6 or pre-v6), before that I had to
replace WQ_MEM_RECLAIM with WQ_RESCUER
and, re-compiled the kernels
shortly after I had booted up the system with the first kernel
(http://git.eu.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5a87b7a5da250c9be6d757758425dfeaf8ed3179)
the output of 'eselect opengl list' did show no opengl backend
selected
so it seems to manifest itself even earlier (ext4: call
mpage_da_submit_io() from mpage_da_map_blocks()) even if only subtly
and over time -
I'm still currently running that kernel and posting from it & having tests run
OK.
Post by Matt
I'm not sure if it's even a problem with ext4 - I haven't had the time
to test with XFS yet - maybe it's also happening with that so it more
likely would be dm-core, like Milan suspected
(http://marc.info/?l=linux-kernel&m=129123636223477&w=2) :(
It'd be interesting to try to reproduce with that same kernel but using
XFS.  I'll check with Milan on what he thinks would be the best next
steps.  Ideally we'll be able to reproduce your results to aid in
pinpointing the issue.  I think Milan will be trying to do so shortly
(if he hasn't started already -- using gentoo emerge, etc).
Post by Matt
even though most of the time it's compiling I don't need to do much -
I need the box for work so if my time allows next tests would be next
weekend and I'm back to my other partition
I really do hope that this bugger can be nailed down ASAP - I like the
improvements made in 2.6.37 but without the dm-crypt multi-cpu patch
it's only half the "fun" ;)
Sure, we'll need to get to the bottom of this before we can have
confidence sending the dm-crypt cpu scalability patch upstream.
Thanks for your testing,
Mike
OK, before bed time I found some kind of corruption:

running kernel is from commit: bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc

the messages might be overseen - so they're difficult to notice:

steps:
1) bootup
2) (might need to re-install graphics driver due to driver switch, in
this case magic properties [or what's its name] didn't change so the
kernel module still worked)
3) firing up 2 xterms, xload, xclock, gksu -> terminal -> firefox,
nautilus --no-desktop, gnome-mplayer (playing mp3)
4) emerge -1 sys-devel/gcc (from one of the xterms)

after emerge -1 sys-devel/gcc

it's solvable by re-install but in case of not-recoverable files (e.g.

I'm not sure if it's even a problem with ext4 - I haven't had the time
to test with XFS yet
I can and have run both -rc3 and -rc4 with Milans patch v6, without any problems at
all, under heavy load and disk I/O. I'm using XFS exclusively. The system
is a testing server and contains 3 harddisks, 2 SATA disks and one SSD.
The whole system runs flawlessly, without any corruption...

Anyway, I run several tests on 2.6.37-rc3+ and see no integrity
problems (using xfs,ext3 and ext4 over dmcrypt).
Not that this might help, but just for testing purposes, I have run all
the -rcX from 2.6.36 on with Milan's patch (XFS filesystem) under heavy
load and disk i/o, and have not encountered a single problem or corruption.

It should be enough to just replace WQ_MEM_RECLAIM to WQ_RESCUER for 2.6.36.
(that define is new in 2.6.37)

noatime,nodiratime,barrier=1
One of my systems runs a squid webcache and has a lot of disk load,
and I've never seen data loss or corruption, all the way up from 2.6.34 to
the latest -git.

(Btw: "noatime" superseeds "nodiratime", you can therefore drop it when
"noatime" is set.)
Post by Matt
I read about barrier-problems and data getting to the partition when
using dm-crypt and several layers so I don't know if that could be
related
I would rather guess that you have filesystem / harddisk problems,
but I must admit I've never mounted one of my filesystems with barriers
enabled (I use XFS exclusively).
