ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.23-rc2/2.6.23-rc2-mm1/

- Added new NFSD development tree as git-nfsd ("J.  Bruce Fields"
  <bfields@fieldses.org>)

- There is a new e1000 driver in git-netdev-all, called e1000e.  I'm sure
  the developers would like it tested.  Please cc netdev@vger.kernel.org on
  any reports.

- I dropped the SSB patches due to various catastrophes and they are being
  redone.  But git-wireless.patch had some dependencies upon SSB which were
  plugged with some nasty bandaids.  So there are some kconfig warnings whcih
  come out of there.  Don't worry about it for now.

- If there's a patch in here which you think should be in 2.6.23 but I do
  not have it designated in that way, please be sure to let me know.

- Apparently the importing of -mm into git (as described in the boilerplate
  below) is not presently working.



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.

Seeing spinlock bad magic BUG's from x86 and x86_64 test boxes,
fsx-linux seems to be tickling it.  Adding Peter as prop_norm_single
seems to be his:

x86 (oai5-hs20):

We also have a third machine which dies when running fs-linux but that
trips a soft-lockup trying to flush the tlb, subsequent stacks also
show prop_norm_single.

x86_64 (elm3b6):

Seeing the following compile error on a G5 mac:

  drivers/video/tdfxfb.c: In function 'tdfxfb_setup':
  drivers/video/tdfxfb.c:1341: error: 'opt' undeclared (first use in this
                                                                 function)
  drivers/video/tdfxfb.c:1341: error: (Each undeclared identifier is
                                                        reported only once
  drivers/video/tdfxfb.c:1341: error: for each function it appears in.)

This seems to be the following fragment from tdfxfb-hardware-cursor:

+               } else if (!strcmp(this_opt, "hwcursor")) {
+                       hwcursor = simple_strtoul(opt + 9, NULL, 0);

I guess the nieve fix would be s/opt/this_opt, but I am also
suspicious of the +9 here as hwcursor is only 8 long?  Now this
seems to take a numeric value and I assume that is via hwcursor=N,
if so then the +9 would make sense _if_ the strcmp was against
"hwcursor=".

Krzysztof?

No, I wasn't aware of it.

I think that something like the appended patch is necessary.

Mariusz, please see if that helps.

Hello,

Don't worry about reproducing untainted, I got the same earlier
and was just preparing and testing the hotfix: here it is...


Nick's mm-clarify-__add_to_swap_cache-locking.patch is fine for mainline,
but soon generates a "kernel BUG at mm/swap_state.c:78!" when it meets
mm-implement-swap-prefetching.patch in 2.6.23-rc2-mm1.  We could add a
fix to the latter, but I think it's better to adjust Nick's, so that
it's right for whichever tree it's in: move the responsibility to
SetPageLocked from read_swap_cache_async to add_to_swap_cache.

I'd assume that the lib/proportions code went and passed a garbage pointer into
spin_lock_irqsave().  Or maybe it has a correct pointer but didn't initialise the
spinlock.

This will be a consequence of that.

umm, possibly.  If we went BUG while holding a spinlock then sure, 
a future lockup is pretty much inevitable.  But the lockdep
uninitialised-lock complaint is a bit of a surprise.

Can you please retest with Hugh's fix applied?

Talking to Peter on IRC he suggested I back out the patch below and
retest on these machines:

	mm-dirty-balancing-for-tasks

One machine seems to have hung elsewhere (probabally another bug sigh),
and one has run the fsx-linux tests successfully.  So this patch does
seem suspect.  I will report back on the other tests when they complete.

umm, I was hoping to find out which of those two patches was the cuplrit.
Almost surely it was 9ee6b32a47b9abc565466a9c3b127a5246b452e5?

OK, thanks for the confirmation.

Here it goes again with a changelog etc.

From: Rafael J. Wysocki <rjw@sisk.pl>

Fix a bug in freezer-introduce-freezer-firendly-waiting-macros.patch which
uses a wrong variable name in wait_event_freezable() and
wait_event_freezable_timeout() (this name is also used in 
wait_event_interruptible() and wait_event_interruptible_timeout() which are
macros and the names clash).

Highly likely it is my patch in #ALL.

lib-make-percpu_counter_add-take-s64.patch looks sensible, but it doesn't
actually work on 32-bit architectures: several users of percpu_counter_add
are passing -unsignedlong as the amount, which is not promoted to s64 in
the desired way, so "df" on extN filesystems is showing silly numbers.

The hack below (say long instead of s64 or s32) may be good as hotfix for
2.6.23-rc2-mm1, but is probably the worst of solutions.  Perhaps take-s64
should be reverted, perhaps there should be a percpu_counter_sub and the
filesystems use that instead of saying -unsignedlong, perhaps they should
use a cast or a long or an s64.  I don't know, but here's this for now...

Well, if you want to clean up your patch queue a bit then I have a few
suggestions for some patches of mine that are currently in -mm that
you could push to Linus.  They are not really important, so if you'd
rather keep them around in -mm until the next merge window then that's
fine by me, but they should be safe to push and would get cut down on
the number of patches you track a bit :-)


This fix was already merged for the ati side of things, this is an
identical fix for the amd side of things - I see no reason why we
shouldn't get this fix into 2.6.23 as well :

 fix-use-after-free--double-free-bug-in-amd_create_gatt_pages--amd_free_gatt_pages.patch


This patch only changes the output of the script when run without
arguments, so as far as building the kernel goes it can't cause any
regressions and it's a clear improvement over what we currently have,
so might as well get it out of your queue and upstream :

 improve-scripts-gcc-versionsh-output-a-bit-when-called-without-args.patch


When people use scripts/ver_linux in bugreports we want correct info -
currently we often print wrong info for the binutils version. This
patch doesn't hurt existing working scenarios but does fix a few
broken ones, might as well get that merged, it's a clear fix :

 scripts-ver_linux-correct-printing-of-binutils-version.patch


These should all be trivially correct since they just remove duplicate
#include's of the same header into a .c file outside any #ifdef and
similar magic, so they should be quite safe to push. Also, I haven't
seen anything but ACK's in response to them (when I've seen a
response), and a few of my similar patches have already been merged :

 powerpc-clean-out-a-bunch-of-duplicate-includes.patch

Thanks.  I think I'll quietly tip the whole patch series overboard and
shoot for a quick rc2-mm2 rather than trying to patch it up in-situ.

I haven't had a chance to review it all in recent months.  Vague first
impressions are that it all goes a bit rampant and changes more than it
needs to, but I'll take a closer look at that if Peter can provide us with
the next version (please).

These broke the IDE controller , using libata on my Dell Workstation .. 

Reverting both fixes the problem.

Great, thanks for working that out.  I'll drop them, thereby breaking other
people's stuff.  This is rather a disaster.

This means it didn't do anything. (wrongly because its checking I/O bits
on a BAR which are ignored according to the spec)

The controller is disabled and when disabled it seems to think its

The box is an Dell Precision WorkStation 530 MT.

Actually I have an ATA-7 disc on the primary EIDE connector ( one port free ) and an oldish CDROM
on the secondary EIDE connector ( one port free ).

If you want me to do/try something let me know.

We seem to have made a mess in there.  timer_list_show() ends up calling
lookup_module_symbol_name(), which takes a mutex.  However print_symbol()
(which is called at oops time, interrupt time, etc) calls
module_address_lookup(), which is basically the same, only it doesn't take
the mutex.

I guess a quicky fix would be to switch
kernel/time/timer_list.c:print_name_offset() from
lookup_module_symbol_name() to module_address_lookup().  But we'd still
have a mess in there.

Hmm, yeah I like this better, it is more like add_to_page_cache now.

All drivers were converted to no longer use xtime directly since it 
might be quite outdated, but this patch adds a usage of xtime.tv_nsec
as RNG...

This code doesn't care if the time is outdated, as it is simply
periodically perturbing an RNG, but OK.

So, what interface are we supposed to be using instead?  I cannot use
get_random_bytes() due to locking issues.  This is not a cryptographically
secure usage, so the perturbation does not need to be extremely high
quality.

On x86, I would just grab the low-order bits of the TSC, but all of the
world is not an x86.  ;-)

							Thanx, Paul

One used to use sched_clock() for this, then get frowned at.  Now we
have cpu_clock()...

I should have been a bit more concrete:

I have a patch pending to unexport xtime for catching unsafe usages, and 
you added an (ab)user.

I don't think rcutorture matters for this bug.  As far as I can tell, Andrew's
description of this problem will always apply to this particular sysrq: the
keyboard interrupt leads to handle_sysrq, which leads to timer_list_show,
which leads to lookup_module_symbol_name, which acquires a mutex.

Hello,

	And the winner of today is ...



=========================================================
[ INFO: possible irq lock inversion dependency detected ]
2.6.23-rc2-mm1 #7
---------------------------------------------------------
runscript.sh/5843 just changed the state of lock:
 (_xmit_ETHER){-+..}, at: [<c03cbe79>] dev_watchdog+0x17/0xcc
but this lock took another, soft-irq-unsafe lock in the past:
 (&tp->lock){--..}

and interrupts could create inverse lock ordering between them.


other info that might help us debug this:
no locks held by runscript.sh/5843.

Maybe not but that's the only way I could trigger it (insmod rcutorture and sysrq+q).

hm, current upstream does:

 static void print_name_offset(struct seq_file *m, void *sym)
 {
         char symname[KSYM_NAME_LEN];

         if (lookup_symbol_name((unsigned long)sym, symname) < 0)

why was that changed? I think symbol lookups for debug purposes have to 
be lockless, fundamentally.

It wasn't.  lookup_symbol_name() calls lookup_module_symbol_name() which
calls mutex_lock().

Sure, especially a sysrq thingy.

It's a bit nasty to just go in there and start walking data structures
without holding the needed lock though.

Hmmm...  And cpu_clock() is not in 2.6.22, so must appear in some later
release.  Which means that the rate of API change in this area is a
bit high, so I should avoid it like the plague.  Therefore, I should
look for some other convenient source of entropy.

One convenient source would the per-CPU statistics that rcutorture
maintains.  Of course, a given CPU's RNG is nearly in lock-step with
its own statistics, but not with the adjacent CPU's statistics...

I will send a patch.

Please use cpu_clock().  It ain't going away.

Errmmm...  No joy.

	ERROR: "cpu_clock" [kernel/rcutorture.ko] undefined!

Turns out that cpu_clock also ain't exported, and rcutorture.c is
a module.  Would adding an EXPORT_SYMBOL_GPL() as in the patch below
be acceptable?

If not, I have a tested patch to rcutorture.c that leverages statistical
counters.  Your choice.

						Thanx, Paul

Add an EXPORT_SYMBOL_GPL() for cpu_clock() and make rcutorture.c use it.
Compiles, but not yet tested.

Except that the old xtime symbol was EXPORT_SYMBOL() rather than my
proposed EXPORT_SYMBOL_GPL() for the equivalent new cpu_clock().

Sigh!!!  I will leave this one for others to sort out.

Andrew, please consider this patch withdrawn and apply the version that
does not rely on time for entropy.  Please let me know if you would like
me to resend it.

Oh no, it was! commit 9d65cb4a1718a072898c7a57a3bc61b2dc4bcd4d

	Fix race between cat /proc/*/wchan and rmmod et al

	kallsyms_lookup() can go iterating over modules list unprotected which is OK
	for emergency situations (oops), but not OK for regular stuff like
	/proc/*/wchan.

I imagine user running powertop which IIRC trolls /proc/timer_list and
doing rmmod following powertop instructions.

Yep.

Thank you!

Just for the record, given that the xtime API that it replaces
was EXPORT_SYMBOL(), I would have not objection to this also being
EXPORT_SYMBOL().  That said, I know of no specific reason for it being
other than EXPORT_SYMBOL_GPL().

						Thanx, Paul

It looks like this was possible after David's fix, which really
enabled running of the handler in free_irq, but before Andrew's patch
disabling local irqs for this time.

So, this bug should be fixed, but IMHO similar problem is possible in
request_irq. And, I think, this is not only about lockdep complaining,
but real lockup possibility, because any locks in such a handler are
taken in another, not expected for them context, and could be
vulnerable (especially with softirqs, but probably hardirqs as well).

This shows that a driver's irq handler was running both in hard interrupt
and process contexts with irqs enabled. The latter was done during
free_irq() call and was possible only with CONFIG_DEBUG_SHIRQ enabled.
This was fixed by another patch.

But similar problem is possible with request_irq(): any locks taken from
irq handler could be vulnerable - especially with soft interrupts. This
patch fixes it by disabling local interrupts during handler's run. (It
seems, disabling softirqs should be enough, but it needs more checking
on possible races or other special cases).

This patch is recommended to all stable versions since 2.6.21, too.

So, this time I f-ed the diff part: it's not exactly against 2.6.23-rc-git6.
But, it's Andrew to blame: he should've known that some old & slow chips
can't do science and poetry at the same time. Sorry (for him)!

Anyway, beside an offset, should be OK...

IMHO, this should be fixed by last changes to free_irq & request_irq.
(Seems to be possible only with CONFIG_DEBUG_SHIRQ?) Otherwise I can
be CC-ed - my pleasure!

OOPS! But, since it's about inversion - not state - there should be no
connection... Anyway if this returns currently (and if _SHIRQ only) I'm
interested.

I tested your patch and it still happens. Dmesg info from patched kernel attached.
I coulnd't reproduce that on 2.6.23-rc3-mm1 - but on 2.6.23-rc2-mm2 it is easily
reproducible.

If you need more info, test some patches, etc. - just mail me.

Pozdrawiam,

It's OK! These're 2 different warnings. As a matter of fact, my patch
wasn't supposed to fix any of them, but something similar to the first
one, which was possible, but for some reason wasn't reported by
lockdep.

The first warning was fixed by Andrew Morton's patch to free_irq(),
so it shouldn't happen in -rc3-mm. The second warning could have been
fixed too, I don't know, but since it's quite long, I would prefer to
think about it only if it still happens in current -mm's.

Thanks,
Jarek P.
