I have a memory leak in scsi_cmd_cache.
Attached is a pretty graph made by munin, and you can see slab_cache
growing constantly since last reboot. Also attached is /proc/config.gz
And here is a copy of /proc/meminfo and /proc/slabinfo
I'm rebooting now since my system is all but unusable (so the mem stats
will reset), but if you need any more info let me know.

You're no the only one. Please send the full `dmesg -s 1000000' output so
we can see which devices and drivers are in use.
Thanks.

does this happen without the binary nvidia driver too? (it appears
you're using that). That's a good datapoint to have if so...

btw please post an lsmod, so that we can find "common" things with the
other reporters of this issue, and thus maybe are able to get closer to
the issue by reducing the candidates...

I don't actually have any scsi devices, it's being used by sata (and usb I
guess). That's why I sent to linux-ide.

I had the exact same nvidia driver with 2.6.12 (just recompiled) and it
didn't happen there.
But just in case I used slabtop to watch scsi_cmd_cache grow by 1.24KB per
second (104MB per day), then I rmmoded nvidia and watched it grow by
1.16KB per second.
The speed is not constant, watching it, and listening to the disks, it
looks like it grows with each IO request.

Here is my lsmod, but since I compile most things into the kernel the
config.gz I sent earlier is probably much more useful.
And BTW I don't even have any scsi devices. scsi is being used by sata and
usb storage.

please repeat this without nvidia ever being loaded. Just having a
module loaded before can already cause corruption that ripples through
later, so just unloading is not enough to get a clean result.
<lsmod snipped>
I see you also use vmware. The other person who reported this also uses
vmware. Could you please repeat the test without BOTH the nvidia and
vmware modules?

Arjan,
Forgot to mention as well... Anton Titov reported this problem, and after
going over his boot-time dmesg again it appears he's not tainting his kernel
at all.

and you're not using nvidia either? can you see if you have
modules/drivers in common with this reporter to see if there maybe are
common suspects?

No - I am tainting with NVIDIA unfortunately. I was trying to find the time to
diagnose sans NVIDIA when Anton reported the same leak (turns out he has the
same Asus P5GDC-V Deluxe board), only in his dmesg he is not tainting at all.
We did determine that Anton and I both use the Marvell sk98lin patch for our
Yukon2s. However, Anton reported other servers using this patch with no leak.
Ariel - are you using sk98lin? The only other modules I'm using are the ALSA
modules for snd-hda-intel as of ALSA version 1.0.11-rc2.

Hrmph, yeah one of my workstations is exhibiting this too. I use
the nvidia module, but I did clean reboot without it loaded and the
leak was still there. So I'll add my data points at
http://audible.transient.net/~jamie/k/ ... all the files starting with
"scsi_cmd_cache."

I rebooted without nvidia or vmware ever being loaded and got a
leak of 1.12KB/s. So I think we can rule that out.
A commonality I'm noticing is SATA. SATA had a big update in this
version, so perhaps that's where to start looking.

Not that I know of. I'm using the kernel from debian unstable, so it's
whatever patches they use:
http://svn.debian.org/wsvn/kernel/releases/linux-2.6/2.6.15-2/debian/patches/?rev=0&sc=0
Are you using SATA?

I wonder if it can be narrowed even more, like to the exact chipset
driver?

Anton and I use an Intel 82801 (ICH6). Ariel's dmesg doesn't look like an ICH6
to me at first glance, but he's also on ata_piix.

I'm on ICH5, but also Sil3112 and HighPoint 372N.
Jamie has ICH6 and Sil3112.
ata_piix seems like it's in common for all, but this is not a lot of
systems, so it could just be a coincidence and the problem caused by
something that's not chipset specific.

Hmm. I just moved my sata_sil stuff out of the way and rebooted:
$ uptime; grep scsi_cmd_cache /proc/slabinfo
23:22:16 up 4 min, 1 user, load average: 0.00, 0.03, 0.00
scsi_cmd_cache 1200 1200 384 10 1 : tunables 54 27 8 : slabdata 120 120 0
My other workstation also runs 2.6.15.1 but uses sata_nv and doesn't
exhibit the problem.

The SATA low level driver is very unlikely to play a role in this. But
you are both using md (raid1 to be specific) on top of scsi, I'd say
that's the best clue. I'd very much doubt the nvidia module as well.

8 : slabdata 120 120 $
Is this good or bad? I'm guessing it means it's still leaking. So it's
really starting to look like ata_piix is the problem. But we need someone
who has the leak to remove that and see if it helps. I can't, since my
drives are connected to it.
And developers:
Can anyone PLEASE take a look at this? We've got 4 confirmed reports of
it, and it's nothing to do with a tainted module. Take a look at this
slabtop output:
OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME
1230120 1230120 100% 0.38K 123012 10 492048K scsi_cmd_cache
I have a 492MB leak! And notice how objects never become unused - that
looks like the problem.

True, my sata_nv box doesn't use md. OTOH, my machines running raid1
on an LSI (MPT Fusion driver) SCSI controller don't have this leak.

FWIW, a bit of negative-confirmatory evidence: I have a sym53c875
and non-SATA IDE drive on this 2.6.15.1, and there is no leak,
nor was there in 2.6.15:

Those SCSI LLD don't support ordered flush barriers, that's why.

It's not a bad data point, it just confirms that setting ->ordered_flush
to 0 in the SATA drivers will fix the leak. So really, it's as expected.
So far apparently nobody tried it, suggested it twice.

In case you still wanted the data point, I just set ordered_flush to 0 on my
ata_piix and the slab leak disappeared.

Are all sata drivers affected by this bug in 2.6.15?
Any 'official' patch available?
Or is the recommended workaround to set ordered_flush to 0 to fix this..
does that have any downsides?

Well, all SCSI drivers are affected by it, yes. However, SATA devices
are peculiarly affected because the ordered_flush method of enforcing
barriers, which is where the leak is, can only be implemented for
devices that don't do tag command queueing (i.e. don't have multiple
commands outstanding for a given single device). By and large, SATA
drivers are the only drivers in the SCSI subsystem that can't do tag
command queueing, which is why the problem didn't show up for any other
type of SCSI driver.
> Any 'official' patch available?
Well, yes, 2.6.16-rc1 has this fixed. I can't see backporting this to
2.6.15.x since it represents a significant functionality enhancement as
well, so I'd lean towards just forcing ordered_flush to zero in 2.6.15.x
which seems to be the best bug fix.

setting ordered_flush to zero for 2.6.15 turns off the flushing
functionality and restores the old behaviour. I don't see that there
would be any down side to this.

2.6.15 didn't support barriers for anything other than ordered flush
SCSI low level drivers, hence only SATA is affected.

Agree, backporting the barrier rewrite would be insane for stable.

Just the usual correctness issue, but since it's leaky it doesn't seem
like a big deal to wait for 2.6.16.
So here's a patch for 2.6.15:
---
Turn off ordered flush barriers for SCSI driver, since the SCSI barrier
code has a command leak.
