- Compilation is busted on mips due to the page-flags patches
- Compilation is busted on sparc64 due to the page-flags patches
- Compilation is partially busted on powerpc due to the page-flags patches.
It compiles for my g5 but allmodconfig fails.
- git-drm is dropped due to build errors
- git-xfs is dropped due to failure to get a clean git diff
- git-slub has been temporarily replaced by git-pekka. Pekka is standing in
while Christoph is away.
- git-kvm is dropped due to clashes with git-s390
- Many patches which weren't in 2.6.25-rc8-mm1's git-x86.patch and
git-sched.patch have now (belatedly) been introduced.
x86 works for me, but Rafael is reporting some crashes.
Boilerplate:
- See the `hot-fixes' directory for any important updates to this patchset.
- To fetch an -mm tree using git, use (for example)
git-fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git tag v2.6.16-rc2-mm1
git-checkout -b local-v2.6.16-rc2-mm1 v2.6.16-rc2-mm1
- -mm kernel commit activity can be reviewed by subscribing to the
mm-commits mailing list.
echo "subscribe mm-commits" | mail majordomo@vger.kernel.org
- If you hit a bug in -mm and it is not obvious which patch caused it, it is
most valuable if you can perform a bisection search to identify which patch
introduced the bug. Instructions for this process are at
http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt
But beware that this process takes some time (around ten rebuilds and
reboots), so consider reporting the bug first and if we cannot immediately
identify the faulty patch, then perform the bisection search.
- When reporting bugs, please try to Cc: the relevant maintainer and mailing
list on any email.
- When reporting bugs in this kernel via email, please also rewrite the
email Subject: in some manner to reflect the nature of the bug. Some
developers filter by Subject: when looking for messages to read.
- Occasional snapshots of the -mm lineup are uploaded to
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/mm/ and are announced on
the mm-commits list. These probably are at least compilable.
- More-than-daily -mm snapshots may be found at
http://userweb.kernel.org/~akpm/mmotm/. These are almost certainly not
compileable.

I bisected boot hang after "ACPI: using IOAPIC for interrupt routing"
down to git-pekka.

P.S.: I now suspect that one bisection point was wrong, however,

I bisected boot hang after "ACPI: using IOAPIC for interrupt routing"
down to git-pekka.

P.S.: I now suspect that one bisection point was wrong, however,

That's odd. I don't immediately see anything there that can cause a

If so, can you do a git bisect? Does sysrq-t tell us anything?

On ia64/NUMA box (which has empty nodes.)
CONFIG_SLAB ..... booted well
CONFIG_SLUB ..... can't boot
CONFIG_SLUB + CONFIG_SLUB_DEBUG_ON .... booted. Hmm?
I'll dig more if I can.
2.6.25-rc8-mm1 had no troubles.

What happens when it doesn't boot? Does it hang or do you get an oops?
Can you reproduce it with the 'for-mm' branch of:
git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6.git

Alexey, can you try passing the 'slub_nomerge' option to the kernel to
see if the hang goes away with that?

SLUB: Add KICKABLE to avoid repeated kick() attempts
Add a flag KICKABLE to be set on slabs with a defragmentation method
Clear the flag if a kick action is not successful in reducing the
number of objects in a slab. This will avoid future attempts to
kick objects out.
The KICKABLE flag is set again when all objects of the slab have been
allocated (Occurs during removal of a slab from the partial lists).

Is this due to the generic_find_next_le_bit compile error I reported as
2.6.25 regression (there seems to be some discussion recently how to
fix it - hopefully for 2.6.25) or is there even more breakage in -mm?

nomerge doesn't help as well as turning on combinations of SLUB debug options.

The winner is partly me, partly git-libata-all.
The latter introduced CONFIG_ATA_SFF option and put more or less every
SATA and PATA driver under it. The former honestly answered N to when
ATA_SFF popped up and failed to check existence of ATA_PIIX and
PATA_JMICRON in failing .config .
Now raise hands those who knew that your ATA controller is SFF
compliant.

Yes, it's the bitops screwup.
I saw some related linux-ext4 email float past yesterday, so something
might be happening.

Was in the middle of a bisection chasing a different problem, and hit this
pair of warnings. 'quilt top' at the time was remove-div_long_long_rem.patch
(in other words, very nearly all of rc8-mm2 was applied). Feel free to delete
if it's known-fixed in one of the last 100 or so patches. ;)

yup, remove-div_long_long_rem.patch is a "good" bisection point (one with
no known fixes against it).

So that may well be a destined-for-2.6.25 problem.

Is there any technical reason why we have to bother users with the
ATA_SFF option at all?
It sounds like a perfect canndidate for being select'ed.

OK, I found the issue I was chasing when I noticed the WARN from genapic_64.c.
After seeing that I'd gotten all the way to remove-div_long_long_rem.patch I
took a close look at the remaining several dozen patches, and took a wild
stab in the dark.. .and ta-da...
PROFILE_LIKELY broke between -rc8-mm1 and -rc8-mm2. Setting it to 'y'
gets me an instant reboot similar to what I was seeing against -rc2-mm.
And changed between -mm1 and -mm2 (datestamp of 04/08):
patches/profile-likely-unlikely-macros.patch
patches/profile-likely-unlikely-macros-fix.patch
I found the profile-likely-unlikely-macros-fix-2.patch from last time around,
but the code has changed a bunch since then so it isn't a clean apply (and in
fact, it's so different it's not even easily hand-patchable - stuff like
!!(foo) has appeared).

I'm pretty sure this one is for Ingo and Steven to sort out, their
names are all over git-sched.patch for this code.... :)
The following config will actually build on x86_64:
CONFIG_HAVE_FTRACE=y
# CONFIG_FTRACE is not set
CONFIG_FTRACE_STARTUP_TEST=y
However, at boot time, it dies a quick and horrid ker-splat and hangs without
doing anything visible at all, without even the decency of rebooting. I'm going
to guess that the startup test fandangos on memory that wasn't set up by the
non-present CONFIG_FTRACE.
I got into this state by saying 'y' to 'startup test' in make oldconfig,
then deciding I didn't want ftrace so I turned that *one* entry off in
make menuconfig - which left the startup test dangling. Easy local workaround
was to just turn the test off too, so you guys can hash this one out at
your leisure...

'default y' is appropriate, but option that is used to disable a major
swath of legacy code unneeded on modern FIS-based SATA platforms like AHCI.

(Man, everything I look at tonight falls over.. I'm jinxed :)
So I built a kernel with:
% zgrep FTRACE /proc/config.gz
CONFIG_HAVE_FTRACE=y
CONFIG_FTRACE=y
CONFIG_DYNAMIC_FTRACE=y
CONFIG_FTRACE_SELFTEST=y
CONFIG_FTRACE_STARTUP_TEST=y
It ran pretty much OK for about 12 minutes, and then gkrellm reported tons of
system time, and 'top' confirms it:
top - 06:27:28 up 25 min, 3 users, load average: 1.21, 1.20, 1.02

And the CPUs are sitting at around 58C, which is their usual temp when
running flat-out, so there's actual looping happening.
I see this in the dmesg from right around when it went belly-up:

Heh.. yeah, but I have to admit SFF support is cryptic. We can
definitely use some friendly explanation there.

I think you didn't understand my suggestion.
I didn't want to get the code enabled unconditionally, I want kconfig
users to not needlessly being bothered with an option where we could
determine automatically the correct setting.
The patch below implements what I have in mind.
> Jeff
cu
Adrian
<-- snip -->
Making ATA_SFF a user-visible option with the drivers needing it
depending on it caused the following problems:
- people lose their driver when accidentally disabling it
- people not requiring it needlessly enable it
Fortunately, we don't have to bother the user with this option at all
since we can simply select it when it's required.

There is a fix in

Looks like freelist corruption where c->freelist is 0x0000000500000500
and c->offset is zero... Christoph?

I assume you have CONFIG_SLUB_DEBUG enabled but it was left out by the grep?

Indeed. I now dropped the SLUB defragmentation patches from the
'for-mm' branch so Andrew can you please pull the new branch to -mm?

c->offset is zero is okay. Could be a object freepointer corruption
because the first word of the object is overwritten after free. You
need to run with slub_debug on the commandline or CONFIG_SLUB_DEBUG_ON to
debug this.
Anyone know what the possible meaning of 0x0000000500000500 is? I do not
see anything in poison.h.

At this point there is no tie in with slub changes. This is
freepointer corruption that is typical for writing to the object after
free it. Enabling slub debugging is needed to figure out when the object
was overwritten.

Doh! I forgot SLUB debugging again. Apologies and let me reproduce some more.

I can reproduce semi-reliably (by kernel standards) corruption in
kmalloc-2048. No idea if this can explain all "struct file" related
oopses I saw, or SLUB free pointer corruption Pekka and Christoph are
looking into.
8139too and atl1 drivers are in use. 8139too connects to outer world,
atl1 -- to laptop collecting netconsole logs. However, I never managed to
collect late oopses with netconsole even if init scripts which are
shutting down interfaces are disabled. :-(

The slub free pointer corruption is usually a result of the overwrites.

Looks like skb corruption. Would be helpful to have the complete output
though. Does the data in the restored range trigger any memories?

I figured that I would post these without details just so they're out
there. I've had trouble getting netconsole to dump anything when I need
it to. I've also had trouble convincing myself to spend the off-work
hours I need to narrow it down.
The general environment is a AMD64 laptop running 64-bit Gentoo, GCC
4.3.
Problem #1:
Compiling with the stack protector option crashes right after initramfs
loads. I think it might be dying while attempting to mount root.
Simple work around: Don't compile with stack protector.
Problem #2:
Resume from STR. The laptop suspends and goes into suspend state with
the blinking power indicator. On resume, it simply boots normally
instead of resuming. No idea how to debug this one. Bisect I guess.

Yes, there have been a couple of reports of stack-protector problems.

hm. I figured that if suspend worked on the Vaio, it'll work on
everything ;)

If you have the time, please.

Zan, can you please try the latest x86.git tree first? The bug may be fixed
there. If that still fails, please bisect, if you can.
Thanks,

No.
I'm currently tracing this bug and 2.6.24 also has it. :-(

OK, nailed it.
It's commit 5f08e46b621a769e52a9545a23ab1d5fb2aec1d4 aka "atl1: disable broken 64-bit DMA".
With this commit in tree, I can reproduce either
a) kmalloc-2048 corruption after initscripts shutdown eth0
http://marc.info/?l=linux-kernel&m=120820360221261&w=2
b) or oopses at filp_close() first reported long ago
(sorry, can't find that email)
c) or hard hang after initscripts shutdown eth0 with even SysRq not working.
http://marc.info/?l=linux-kernel&m=120795046008115&w=2
I have two boxes one with atl1, 4G RAM with 2G remapped after 4G boundary, another
with r8169 connected with just ethernet cable. NICs agree on 1Gbps speed.
So, it's enough to scp 200 MB git archive and immediately start
rebooting sequence for horrors described above to appear. It's not 100%
reproducible but more like 90%.
I tested 10 times kernel one commit before and it doesn't have these
issues and reboots reliably.

One more question: Does it happen whether or not you're using atl1 as
a netconsole?

Yep. During up or running there were no problems with this card.

I can't duplicate this error, but it's probably because my machine
doesn't have 4GB of memory.
I have one report in Febroary 2008 of another user encountering strange
oopses in 2.6.23.12 and 2.6.24 whenever he downed the interface. I
suspect your experience is a repeat of that.
Just to be clear, you transfer about 200MB to the NIC (Rx direction),
then immediately reboot, right? Can you duplicate the problem if you
simply ifconfig down instead of rebooting after the transfer?
Thanks for your help.

Yup!

Aha, ifconfig down is enough. Here is how reproducer looks like now:
./sync-linux-linus && ssh core2 "sudo /sbin/ifconfig eth0 down"
where first script is basically scp(1).
Also, booting with 1G or 2G of RAM (mem=1024m) makes issue go away.
printk at dev_close() time shows that NETIF_F_HIGHDMA was not somehow
enabled.

Does the problem go away with iommu=nomerge? If so, I suspect we're not
properly flushing an iowrite somewhere.

Looking at how other netdevice drivers:
8139too and others checks netif_running() in interrupt handler.
r8169 has scary "50k$" question comment re irqs disabled after
interacting with hardware.
But the r8169 case should be fixed by atlx_irq_disable()?
Writes to REG_IMR, REG_ISR are commented in atl1_reset_hw(), why?
(I'll test that soon)
Do we have a theory why changing from 64-bit DMA mask to 32-bit mask
resurrects the bug? NIC here never showed any sort of corruption
described in commit which banned 64-bit DMA.

Agreed.

Came from the vendor that way.

We had multiple reports of users who encountered repeated memory
corruption when transferring large files while running with a 64-bit DMA
mask. Chris Snook noticed the upper 32 bits of the descriptor address
register are shared among five other registers, each containing the low
bits for one of five descriptors. All the descriptors, therefore, have
to live within the same 4GB address space.
I'll keep poking at it as time permits through the week, but I probably
won't be able to devote a whole lot of time to it until next weekend.

Make that "...within the same 2GB address space."

I've tried all the stuff you mentioned above, and more, to prevent the
memory corruption, all to no avail.
I booted with mem=4000M and didn't hit the bug. I diffed dmesg between
booting with mem=4000M and booting without it, and found that iommu
was being disabled when booting with full memory:

So I then booted with iommu=allowed. No errors. Can't hit the bug to

Why would disabling iommu cause the atl1 driver to write over poisoned
memory?
Alexey, can you please try booting with iommu=allowed and see if you
avoid the problem?

I see the same thing with a Socked AM2-based board (Asus M2V) with 4GB
RAM installed. The problem occurs only when SWIOTLB is active, which
happens automatically at boot (in arch/x86/kernel/pci-swiotlb.c) when
the page frame number exceeds 1048576 (corresponding to 2^32 bytes).
I thought for awhile that the problem went away with iommu=allowed, but
I was wrong.
The bug appears to be a "simple" skb write-after-free that happens only
when bounce buffers are in use, but I'll be damned if I can find the
cause of it.

Hmmm, there was a wonderful oops on interface stop here when the other end
of atl1 cable was physically unplugged (but there was traffic before):
atl1_down
atl1_clean_rx_ring
swiotlb_unmap_single
swiotlb_unmap_single_attrs
memcpy_c

Try this patch! If scared, remove swiotlb poisoning, I'm not entirely
sure it's correct, but it makes aforementioned second oops
deterministic.

Seems to fix it for me. Nicely done, Alexey! Thanks!
I looked at that blasted unmap a thousand times, but never noticed the
missing buffer_info->dma clear.
I'll get input from one more tester, and if it's positive, I'll submit
this to Jeff.
Thanks again.
