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 ***@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 think I saw something like this on a system with an "older" toolchain.
I'm not seeing it on openSUSE 10.3, though (using gcc 4.2.1).
Added CCs to the experts.
Google turned up this post:
http://sourceware.org/ml/binutils/2006-08/msg00235.html

I have no time to dig more into it the next days.

Hi Andrew,
The 2.6.25-rc3-mm1 kernel panics while bootup on power box. The machine booted up
without the panic on the third attempt, but badness call trace were seen while running
tests
We are taking a HW interrupt ... we aren't supposed to take HW
interrupts that early during boot afaik.

Is it yet another case of somebody hard-enabling interrupts with
local_irq_enable() ?

Ben.

Are we somehow enabling interrupts before we've setup
ppc_md.get_irq?
Yes, we are - it's the semaphore rewrite which is doing this in
start_kernel(). It's being discussed.
Enabling interrupts too early on powerpc was discovered to be fatal on
powerpc years ago. It looks like that remains the case.
Yes, it is and will probably always be. All that semaphore mucking
around that hard-enables interrupts is just asking for trouble (and on
more than just powerpc... heh, how do you do if your main interrupt
controller hasn't even been initialized yet ?)

Thanks, Jiri. Does the following patch work for you?

This patch address the !CONFIG_SECURITY case, but not the case of
using the dummy LSM. The default these days is to have capabilities
compiled in no matter what, but it is still possible to have
CONFIG_SECURITY=y and CONFIG_SECURITY_CAPABILITIES=n, in which
case prctl(0x8) will return -EINVAL. Do we want dummy to call
cap_prctl() as well, or are we ok with userspace getting -EINVAL
given that there are in fact no capabilities at that point and
the userspace code is clearly expecting them?

thanks,
-serge

Subject: [PATCH 1/1] capabilities: use cap_task_prctl when !CONFIG_SECURITY

capabilities-implement-per-process-securebits.patch introduced
cap_task_prctl() and moved the handling of capability-related
prctl into it. So when !CONFIG_SECURITY, the default
security_task_prctl() needs to call cap_task_prctl() the way
other default hooks call capability helpers when they exist.

This fixes a slew of userspace breakages when
CONFIG_SECURITY=n.

Ok. Care to enable CONFIG_DEBUG_KOBJECT, and post the part of the log
that happens right before the WARN()? We might get a hint where to look
for the stuff that goes wrong.

Thanks. Odds are we have some sysfs issue in the module core, that code
really needs to be refactored, I'll go work on it to see if we can try
to isolate all of that code into one file, which should help find these
kinds of things easier.

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.25-rc3/2.6.25-rc3-mm1/
x86_64, mostly 64-bit userspace, Dell Latitude D820, T7200 Core2 Duo...

So I gave CONFIG_PROFILE_LIKELY another try, and this time the thing actually
booted and got into userspace, but stuff started dying in rc.sysinit.

According to dmesg, they all died at the same place:

[ 4.841459] rename_device[686]: segfault at ffffffffff7009be ip ffffffffff7009be sp 7fff7ccfb958 error 14

[ 6.099486] rename_device[1513]: segfault at ffffffffff7009be ip ffffffffff7009be sp 7fff47e88ad8 error 14
[ 5.769289] rename_device[1516]: segfault at ffffffffff7009be ip ffffffffff7009be sp 7fffa317edd8 error 14
[ 7.457229] fsck.ext3[1576]: segfault at ffffffffff7009be ip ffffffffff7009be sp 7fff3be947f8 error 14

(Note that not everything died - some renames, an fsck, and maybe I missed
something - but a lot of other stuff worked (dmesg, grep, cat, uname that I
ran, and a lot of things that rc.sysinit invoked - so that may tell us
something...)

/proc/self/maps says that's near:

ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall]

And my System.map says:

ffffffff80855a0c A __bss_stop
ffffffff80855a0c A _end
ffffffffff600000 T vgettimeofday
ffffffffff600100 t vread_tsc
ffffffffff600122 t vread_hpet
ffffffffff600140 D __vsyscall_gtod_data
ffffffffff600400 T vtime
ffffffffff600800 T vgetcpu
ffffffffff600870 D __vgetcpu_mode
ffffffffff600880 D __jiffies
ffffffffff600c00 T venosys_1
ffffffffff700000 A VDSO64_PRELINK

ffffffffff7005b8 A VDSO64_vgetcpu_mode
ffffffffff7005c0 A VDSO64_vsyscall_gtod_data
<file ends there>

So we're in the same 4K as the VDSO64_* values, but some 0x4fe past the
gtod_data. Anybody got a hint as to what the heck it was doing?

Try this patch:

Remove unlikelies in vsyscall path

Remove unlikely in vsyscall path that conflict with unlikely profiling.
The unlikelies shouldn't be needed anyways because gcc predicts
condition leading to early return as unlikely by default and
for the loops it shouldn't make much difference

inline in a header file. It would be better to add a #define DONT_DO_THAT
I think you need to do it differently. Not undef/define, but set
some symbol that is checked by the unlikely profiler and it won't
enable itself with that symbol set. Then header files would be covered too.

Possible. The problem is that there are now vsyscall functions in
other files too, especially hpet_64.c and tsc_64.c

Perhaps this is something that should be just checked in modpost instead.
Any external references from the vsyscall section to another section
should be flag'ed as error (cc'ed Sam in case he wants to look at that)

at the top, so it'll be something else. Perhaps a `likely' snuck in via an
inline in a header file. It would be better to add a #define DONT_DO_THAT
at the top of arch/x86/kernel/vsyscall_64.c and
arch/x86/vdso/vclock_gettime.c, then use that to defeat likely-profiling.

Confirming that this patch works and my system goes multi-user cleanly.
Thanks.

Likely Profiling Results
These are all the ones which we got wrong on your setup, yes?

I wonder if assuming that current->audit_context is NULL is realistic
nowadays.

So we're in the same 4K as the VDSO64_* values, but some 0x4fe past the
gtod_data. Anybody got a hint as to what the heck it was doing?
Remove unlikelies in vsyscall path
Nope, sorry... same behavior. Apparently it's a (un)likely someplace
else...

I'm trying to figure out what's at 0x9be into the vdso, but not having
a lot of luck.

You can do objdump -Sr on the vdso/vsyscall object files and see
if there are any external references to unlikely related functions. If yes
the problem is in that function

Hi Andrew,

Not able to boot 2.6.25-rc3-mm1 my ppc64 box.
2.6.25-rc2-mm1 and 2.6.25-rc3 boots fine.

I applied slab.c fix also.

Any other known issues ? My config file attached.
Here are the messages on the console.

Thanks,
Badari

Hi Andrew,
Not able to boot 2.6.25-rc3-mm1 my ppc64 box.
2.6.25-rc2-mm1 and 2.6.25-rc3 boots fine.
I applied slab.c fix also.
Any other known issues ? My config file attached.
Here are the messages on the console.
The semaphore consolidation code enables interrupts early in boot, when it
shouldn't. This tends to make powerpc blow up. Could be that this is what
you're hitting.

Matthew, is this ging to be fixed soon?

Thanks.

Yes. I just backed out git-semaphore.patch and machine booted fine.

shouldn't. This tends to make powerpc blow up. Could be that this is what
you're hitting.
Matthew, is this ging to be fixed soon?
There is a new version of these patches in the current linux-next tree ...

Yes, we are - it's the semaphore rewrite which is doing this in
start_kernel(). It's being discussed.
Enabling interrupts too early on powerpc was discovered to be fatal on
powerpc years ago. It looks like that remains the case.
Regarding these issues. I could make it non fatal and just WARN_ON,
provided that I have a way to differentiate legal vs. illegal calls
to local_irq_enable(). We already have that function mostly out of
line in C code due to our lazy irq disabling scheme, so the overhead of
testing some global kernel state would be minimum here.

However, I don't see anything around init/main.c:start_kernel() that I
can use. What do you reckon here we should do ? Add some kind of global
we set before calling local_irq_enable() ? Or make early_boot_irqs_on()
do that generically

It's currently defined as an empty inline without CONFIG_TRACE_IRQFLAGS
but we could make it set a flag instead.

I'm pretty sure other archs have similar problems, especially in the
embedded world where you are booted with random junk firmwares that may
leave devices, interrupt controllers etc... in random state, and
enabling incoming IRQs before the arch code properly initializes the
main interrupt controller can be fatal. I know at least of an ARM board
I worked on a while ago that had a similar issues.

On ppc32, unfortunately, our local_irq_enable/restore are nice inlines
that whack the appropriate MSR bits directly, thus adding a test for a
global flag would add some bloat/overhead that I'd like to avoid, at
least until we decide to also do lazy disabling on those, if ever...

Cheers,
Ben.

I'd have thought that the way to do this would be to add it to lockdep -
lockdep already has all the infrastructure and code sites to do this.

Set some special flag saying its-ok-to-enable-interrupts-now and test that
in lockdep.

akpm:/usr/src/25> grep LOCKDEP arch/powerpc/Kconfig
akpm:/usr/src/25>

losers ;)

Still, doing it for

akpm:/usr/src/25> grep -l LOCKDEP arch/*/Kconfig
arch/arm/Kconfig
arch/avr32/Kconfig
arch/mips/Kconfig
arch/s390/Kconfig
arch/sh/Kconfig
arch/sparc64/Kconfig
arch/um/Kconfig
arch/x86/Kconfig

should give pretty good coverage.

Yes, on powerpc 64 bits, they all go down to one C function that does
the lazy enable/disable, so it would be easy to deal with. 32 bits
doesn't have it that simple tho.

I have lockdep patches for powerpc 32 and 64 bits. They aren't upstream
yet as they need a bit more beating up and there's at least one machine
that doesn't seem to like them, so I'm working on just that. That's a
good idea to add the test to lockdep tho, I'll see what I can do.

Hi,
Post by Andrew Morton
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.25-rc3/2.6.25-rc3-mm1/
ERROR: "probe_4drives" [drivers/ide/ide-core.ko] undefined!
It was also reported by Andrew & Stephen but the thing is that it doesn't
happen here with IDE tree, also it is quite strange that only probe_4drives
causes error and other probe_* variables don't.

I think that it is caused by something else in -mm / linux-next...

Thanks,
Bart

with netconsole. There's another, different, crash I've been seeing a bit
earlier in the shutdown -h as well, but I haven't been able to catch that one

Yes, I hit a similar one during halt on the t61p. But because of the
netconsole bustage I was only able to see (on the screen) oops #2 - oops #1
had scrolled off. oops #2 had a simlar trace and the EIP was in
text_poke().

I suppose one of us should bisect it.

Yes, I hit a similar one during halt on the t61p. But because of the
netconsole bustage I was only able to see (on the screen) oops #2 - oops #1
had scrolled off. oops #2 had a simlar trace and the EIP was in
text_poke().
OK, I finally managed to catch the *other* failure I was seeing at shutdown,
and it appears to be a variant on the same theme, so readers may feel free to
ignore the rest of this note unless they care about the gory details...

Apparently, if I booted with 'ignore_loglevel' (which is my default when using
netconsole), I hit the above traceback and I'm dead in the water, no alt-sysrq,
need to hold down the power button for 5 seconds.

If I boot with 'quiet' instead, I get the below set of tracebacks, which caused
the original BUG to go scrolling off-screen and obfuscating that it's the same
failure. Adding to the confusion, if it failed in this mode, alt-sysrq still
worked just fine, so alt-sysrq-S-S-U-B got me a reboot.

Now that I know that at least *part* of the issue is the same, I can go
bisecting. Somebody *else* can ponder why ignore_loglevel/quiet causes the
big difference in behavior after the BUG, that part is beyond my ken...

I suppose one of us should bisect it.
I'll let you know what I find...

Can you decode ffffffff8020a023 via addr2line please ?
It's been a long day, and I couldn't get addr2line to work, it kept saying '??:0'.

However, this is in my System.map:

ffffffff8020a000 t poll_idle
ffffffff8020a009 t do_nothing
ffffffff8020a00f T set_personality_64bit
ffffffff8020a041 T release_thread
ffffffff8020a07d T arch_randomize_brk

so set_personality_64bit+0x14 or so?

Probably not surprisingly, the quilt bisect says the problem is git-x86,patch.

'shutdown -h' blows up at the very end. shutdown -r works OK.

Nope, still blows up with exactly the same traceback.

I may have to try again to figure out how to bisect the git-x86 tree - Ingo
send me a pointer to his git-x86 cheat sheet, I looked at it but I couldn't
figure out how to tell 'git bisect' that the starting good spot was "whatever
corresponded to the git-x86 patch in 24-rc8-mm1" and bad was "25-rc3-mm1". I
tried using the first commit ID listed in the patch, but that gave me this:

(looking at first few lines of the git-x86.patch in the 25-rc3-mm1 broken-out):

commit fa70e201463a7f3d86b995249e57a8e27b31b5f8
Author: Paolo Ciarrocchi <***@gmail.com>
Date: Sun Feb 24 11:57:22 2008 +0100

but then:

% git bisect bad fa70e201463a7f3d86b995249e57a8e27b31b5f8
fatal: Needed a single revision
Bad rev input: fa70e201463a7f3d86b995249e57a8e27b31b5f8

And I didn't see any release tags in the x86 git tree that I could specify
either.

(Once I get the good and bad markers set, it "should be easy" - I've managed
to git-bisect through Linus's git tree before, but that was always easy
because "bad" was HEAD and "good" had a nice v2.6.2mumble-rcN tag to specify...

Yes, it's all a bit mysterious. I just look in the changelog, which was
pull edout of the git diff via various means.

I *hope* I'm mis-reading Ingo's directions when I cut-n-pasted them -
first I pulled down the two trees, tried to bisect, had it give me the
"need a single revision" error, then I checked out a tree - and got a
*different* funky opaque error message when I tried to bisect:

Obviously, I'm either a *total* git-idiot, or malevolent spirits have taken
up residence in my laptop and are conspiring to prevent me from troubleshooting
this problem... ;)

I may have to try again to figure out how to bisect the git-x86 tree -
Ingo send me a pointer to his git-x86 cheat sheet, I looked at it but
I couldn't figure out how to tell 'git bisect' that the starting good
spot was "whatever corresponded to the git-x86 patch in 24-rc8-mm1"
and bad was "25-rc3-mm1". I tried using the first commit ID listed in
the best way to bisect the x86.git-only commits is to do:

git-bisect bad x86/latest
git-bisect good x86/base

the 'base' branch is the upstream tree that x86.git is based against.
This will minimize the number of bisection points as well, because
you'll only bisect x86.git patches.

[ and make sure you test x86/base first to establish that it's truly
'good' :-) ]

OK, *that* got the bisect running. However, after a few bisections, things
are getting weird...

(Note - I haven't done a git pull or update for a week and a bit, so the tree is
as of 03/14 or so...)

'git bisect log' reports:

At this point, 'git bisect visualize' shows 9 commits left to bisect through,
and all are dated 03/10 or later. However, since 25-rc3-mm1 had the problem,
it had to be something in-tree as of 03/05.

Is it possible that the problem code was in the git-x86 tree when Andrew
pulled for -rc3-mm1 and -rc5-mm1, but had been reverted by the time I grabbed
the tree, so the /x86/base' was in fact *good* by that point?

no, we frequently regenerate the x86.git tree so the dates have little
relevance. If for any particular pull, x86/base is good and x86/latest
is bad, then the bug is somewhere in those 200-300 patches inbetween.
They are lined up linearly so should be perfectly bisectable.

OK, off to go try the last few bisects then...

well ... your git bisection log does look suspiciously 'good', so
something is wrong thee i think :-(

the chance to get 8 'good' bisection points in a row is 1:256. OTOH, the
freshest x86 patches are always at the 'end' of the queue - which are
also the ones most likely to break anything.

Are you sure the x86/base point is indeed 'good'? You can check it via:

git-checkout -b tmp x86/base

and build+boot it.

On the other hand, this was broken in 25-rc3-mm1, so it's not a "fresh"
patch...

Did that, and it's good (as in 'shutdown -h now' powers off rather than BUG and
hanging).

"You're at Witt's End" -- Adventure, c. 1978

OK.. so far I've got:

25-rc3-mm1 is bad
25-rc5-mm1 is bad, and bisected down to git-x86.patch
x86/base as pulled last week is good
bisected to within the last 9 entries of x86/latest is good.

So I can't seem to replicate it using the git-x86 tree, but bisecting -mm
implicates it. How very strange.

I even went and pulled Andrew's mmotm pile as of this afternoon, and got that
to built after having to heave only a dozen patches over the side and one or
two hand-fixes of patches - and *that* one is good too.

So I'm thinking that it was some "bump in the night" that was broken in the
x86 tree when Andrew pulled it for 25-rc5-mm1, but was fixed by the time I
pulled it a few days later to start git-bisecting it.

Given that -mmotm isn't showing the problem, I'm having a hard time coming
up with enthusiasm to keep chasing it. If I see it happen again in a -mm
or Linus kernel, I'll restart the chase then....

if it ever reappears then please check x86/latest first (without any
other -mm bits) and notify us.
