Hi all,
Changes since 20081210:
New tree:
nommu
Undropped tree:
sound
Dropped trees (temporarily):
v4l-dvb (build problem)
mtd (difficult conflicts)
drm (build problem)
semaphore-removal (due to unfixed conflicts against Linus' tree)
cpu_alloc (build problem)
perfmon3 (concerns from the x86 team)
audit (difficult conflicts)
nommu (build problem)
staging (build failure)
The driver-core tree gained a build failure that needed a commit reverted.
The ftrace tree gained a conflict against Linus' tree.
The pci tree gained a conflict against the driver-core tree.
The mtd tree gained 3 conflicts against the arm tree which I could not
easily resolve, so it was dropped.
The ttydev tree gained a conflict against the async_tx tree requiring a
commit from the async_tx tree to be reverted.
The nommu tree gained conflicts against the slab and kmemcheck trees and
also a build failure so it was dropped.
----------------------------------------------------------------------------
I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git
(patches at
http://www.kernel.org/pub/linux/kernel/people/sfr/linux-next/). If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one. You should use "git fetch" as mentioned in the FAQ on the wiki
(see below).
You can see which trees have been included by looking in the Next/Trees
file in the source. There are also quilt-import.log and merge.log files
in the Next directory. Between each merge, the tree was built with
a ppc64_defconfig for powerpc and an allmodconfig for x86_64. After the
final fixups (if any), it is also built with powerpc allnoconfig,
44x_defconfig and allyesconfig (minus CONFIG_PROFILE_ALL_BRANCHES) and
i386, sparc and sparc64 defconfig.
Below is a summary of the state of the merge.
We are up to 132 trees (counting Linus' and 15 trees of patches pending for
Linus' tree), more are welcome (even if they are currently empty).
Thanks to those who have contributed, and to those who haven't, please do.
Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next . If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.
Thanks to Jan Dittmer for adding the linux-next tree to his build tests
at http://l4x.org/k/ , the guys at http://test.kernel.org/ and Randy
Dunlap for doing many randconfig builds.
There is a wiki covering stuff to do with linux-next at
http://linux.f-seidel.de/linux-next/pmwiki/ . Thanks to Frank Seidel.

Hi.
I'm seeing this warning early in boot logs. It does not appear on 2.6.28-rc7.
Not sure how long it's been around. Haven't built -next for some time.

The warning can also be reproduced in qemu, so it was easy to bisect.
commit 7317d7b87edb41a9135e30be1ec3f7ef817c53dd
Author: Nick Piggin <nickpiggin@yahoo.com.au>
Date: Tue Sep 30 20:50:27 2008 +1000
sched: improve preempt debugging
This patch helped me out with a problem I recently had....
Basically, when the kernel lock is held, then preempt_count
underflow does not
get detected until it is released which may be a long time (and arbitrarily,
eg at different points it may be rescheduled). If the bkl is released at
schedule, the resulting output is actually fairly cryptic...
With any other lock that elevates preempt_count, it is illegal to schedule
under it (which would get found pretty quickly). bkl allows scheduling with
preempt_count elevated, which makes underflows hard to debug.
Signed-off-by: Ingo Molnar <mingo@elte.hu>
I understand that not this particular commit is buggy, but at least
I've got someone to add to the CC. ;)
Also the author's e-mail looks suspicious.

Possibly. But that may be because most people don't have DEBUG_PREEMPT.

Hmm. _local_bh_enable() would make the preempt_count go negative or fall
below 1 (with kernel lock held).

.. and it happens early on, when we take an interrupt in check_bugs.
Are we ready to enable interrupts there? Maybe the page fault we took (on
purpose) enabled interrupts and we now take the irq much too early.
Or maybe the initial kernel lock didn't set preempt_count to 1.
Ingo, any ideas?

hm, i never saw this warning and i run tons of different kernels (on
different hw with different build environments) so if this was a more
generic BKL init problem i'd expect to have seen it one way or another.
But i think the bug that Alexey is seeing is genuine:

i dont think it's a BKL problem - i think something in linux-next which
went upstream recently leaked a preempt count.
What is weird is that we have detection for softirq preemption leaks:
if (unlikely(prev_count != preempt_count())) {
printk(KERN_ERR "huh, entered softirq %td %p"
"with preempt_count %08x,"
" exited with %08x?\n", h - softirq_vec,
h->action, prev_count, preempt_count());
preempt_count() = prev_count;
And this did not appear to have triggered for Alexey. So this probably
cannot be a softirq handler leak, nor an initcall handler leak.
The only possibility seems to be for this to be a preempt leak in hardirq
handler - i.e. locking inbalance by some driver. It did not get detected
there (because the preempt count was kept elevated by the BKL and by the
softirq handler), but when the softirq got released. The stack has some
hardirq signs, but no specific blame for which driver might be
responsible.
This would be a candidate for bisection i suspect, barring any better,
more specific ideas (like a specific timeframe for when this hit upstream,
or a better stacktrace of the hardirq context that triggered this softirq
instance).

Not really. As I mentioned before, It is reproducible in qemu, but
happens a bit earlier:

sched: improve preempt debugging
This patch helped me out with a problem I recently had....
Basically, when the kernel lock is held, then preempt_count
underflow does not
get detected until it is released which may be a long time (and arbitrarily,
eg at different points it may be rescheduled). If the bkl is released at
schedule, the resulting output is actually fairly cryptic...
With any other lock that elevates preempt_count, it is illegal to schedule
under it (which would get found pretty quickly). bkl allows scheduling with
preempt_count elevated, which makes underflows hard to debug.

so at least a dumb bisection won't do here.

ah, sorry for being a slow starter, i missed that bit - merge window
attention span troubles ...
I think the kernel_locked() check added here is plain buggy against IRQ
contexts: we drop the BKL spinlock and reduce current->kernel_depth
non-atomically.
So kernel_locked() can become detached from the preempt_count().
Nick, can you think of any better way of still saving this debug check, or
should we revert it?
Although it seems a bit weird how consistently you seem to be able to
trigger it - as this seems to be a narrow race. Is there an IRQ storm
there perhaps, or something widens things up for Qemu to inject an IRQ
right there?
Ingo

I'm not sure about the qemu case, but at least on my laptop it happens
somewhere along
arch/x86/kernel/cpu/bugs.c:
92 printk(KERN_INFO "Checking 'hlt' instruction... ");
93 if (!boot_cpu_data.hlt_works_ok) {
94 printk("disabled\n");
95 return;
96 }
97 halt();
98 halt();
99 halt();
100 halt();
101 printk("OK.\n");
where an interrupt has to come in order to get the cpu from hlt, so
there is no surprise that I'm seeing this on every single boot. ;)

Hi all,
My usual call for calm: please do not put stuff destined for 2.6.34 into
linux-next trees until after 2.6.33-rc1.
Changes since 20091210:
Since Linus is now merging trees into his, various conflicts move from
tree to tree.
The origin tree lost its build failure.
The microblaze tree lost its conflict.
The ext4 tree lost its build failure.
The rr tree lost its conflict, but gained a build failure for which I
applied a patch.
The trivial tree lost its conflicts.
The usb tree still has its build failure for which I reverted a commit.
----------------------------------------------------------------------------
I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/v2.6/next/ ). If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one. You should use "git fetch" as mentioned in the FAQ on the wiki
(see below).
You can see which trees have been included by looking in the Next/Trees
file in the source. There are also quilt-import.log and merge.log files
in the Next directory. Between each merge, the tree was built with
a ppc64_defconfig for powerpc and an allmodconfig for x86_64. After the
final fixups (if any), it is also built with powerpc allnoconfig (32 and
64 bit), ppc44x_defconfig and allyesconfig (minus
CONFIG_PROFILE_ALL_BRANCHES - this fails its final link) and i386, sparc
and sparc64 defconfig. These builds also have
CONFIG_ENABLE_WARN_DEPRECATED, CONFIG_ENABLE_MUST_CHECK and
CONFIG_DEBUG_INFO disabled when necessary.
Below is a summary of the state of the merge.
We are up to 155 trees (counting Linus' and 22 trees of patches pending
for Linus' tree), more are welcome (even if they are currently empty).
Thanks to those who have contributed, and to those who haven't, please do.
Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next . If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.
Thanks to Jan Dittmer for adding the linux-next tree to his build tests
at http://l4x.org/k/ , the guys at http://test.kernel.org/ and Randy
Dunlap for doing many randconfig builds.
There is a wiki covering stuff to do with linux-next at
http://linux.f-seidel.de/linux-next/pmwiki/ . Thanks to Frank Seidel.
