[PATCH 00/11] [ANNOUNCE] 3.0.12-rt30-rc2

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 2938 bytes --]


Dear RT Folks,

This is the RT stable review cycle of patch 3.0.12-rt30-rc2.

Please scream at me if I messed something up. Please test the patches too.

The difference between this and -rc1 was I fixed up the patches to
add the changes, instead of removing them :)

I also added the missing commit: 
KVM: fix XSAVE bit scanning (now properly)
That Thomas pointed out was missing.


The -rc release will be uploaded to kernel.org and will be deleted when
the final release is out. This is just a review release (or release candidate).

The pre-releases will not be pushed to the git repository, only the
final release is.

If all goes well, this patch will be converted to the main release
next on Wednesday (11/7/2011).

Enjoy,

-- Steve

[PATCH 01/11] tasklet/rt: Prevent tasklets from going into infinite spin in RT

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 12636 bytes --]

From: Ingo Molnar <mingo@elte.hu>

When CONFIG_PREEMPT_RT_FULL is enabled, tasklets run as threads,
and spinlocks turn are mutexes. But this can cause issues with
tasks disabling tasklets. A tasklet runs under ksoftirqd, and
if a tasklets are disabled with tasklet_disable(), the tasklet
count is increased. When a tasklet runs, it checks this counter
and if it is set, it adds itself back on the softirq queue and
returns.

The problem arises in RT because ksoftirq will see that a softirq
is ready to run (the tasklet softirq just re-armed itself), and will
not sleep, but instead run the softirqs again. The tasklet softirq
will still see that the count is non-zero and will not execute
the tasklet and requeue itself on the softirq again, which will
cause ksoftirqd to run it again and again and again.

It gets worse because ksoftirqd runs as a real-time thread.
If it preempted the task that disabled tasklets, and that task
has migration disabled, or can't run for other reasons, the tasklet
softirq will never run because the count will never be zero, and
ksoftirqd will go into an infinite loop. As an RT task, it this
becomes a big problem.

This is a hack solution to have tasklet_disable stop tasklets, and
when a tasklet runs, instead of requeueing the tasklet softirqd
it delays it. When tasklet_enable() is called, and tasklets are
waiting, then the tasklet_enable() will kick the tasklets to continue.
This prevents the lock up from ksoftirq going into an infinite loop.

[PATCH 02/11] genirq: fix regression in irqfixup, irqpoll

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 1582 bytes --]

From: Edward Donovan <edward.donovan@numble.net>

Commit fa27271bc8d2("genirq: Fixup poll handling") introduced a
regression that broke irqfixup/irqpoll for some hardware configurations.

Amidst reorganizing 'try_one_irq', that patch removed a test that
checked for 'action->handler' returning IRQ_HANDLED, before acting on
the interrupt.  Restoring this test back returns the functionality lost
since 2.6.39.  In the current set of tests, after 'action' is set, it
must precede '!action->next' to take effect.

With this and my previous patch to irq/spurious.c, c75d720fca8a, all
IRQ regressions that I have encountered are fixed.

[PATCH 03/11] intel-iommu: Fix AB-BA lockdep report

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 6985 bytes --]

From: Roland Dreier <roland@purestorage.com>

When unbinding a device so that I could pass it through to a KVM VM, I
got the lockdep report below.  It looks like a legitimate lock
ordering problem:

 - domain_context_mapping_one() takes iommu->lock and calls
   iommu_support_dev_iotlb(), which takes device_domain_lock (inside
   iommu->lock).

 - domain_remove_one_dev_info() starts by taking device_domain_lock
   then takes iommu->lock inside it (near the end of the function).

So this is the classic AB-BA deadlock.  It looks like a safe fix is to
simply release device_domain_lock a bit earlier, since as far as I can
tell, it doesn't protect any of the stuff accessed at the end of
domain_remove_one_dev_info() anyway.

BTW, the use of device_domain_lock looks a bit unsafe to me... it's
at least not obvious to me why we aren't vulnerable to the race below:

  iommu_support_dev_iotlb()
                                          domain_remove_dev_info()

  lock device_domain_lock
    find info
  unlock device_domain_lock

                                          lock device_domain_lock
                                            find same info
                                          unlock device_domain_lock

                                          free_devinfo_mem(info)

  do stuff with info after it's free

However I don't understand the locking here well enough to know if
this is a real problem, let alone what the best fix is.

Anyway here's the full lockdep output that prompted all of this:

[PATCH 04/11] KVM: Sanitize cpuid

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 2987 bytes --]

From: Avi Kivity <avi@redhat.com>

Instead of blacklisting known-unsupported cpuid leaves, whitelist known-
supported leaves.  This is more conservative and prevents us from reporting
features we don't support.  Also whitelist a few more leaves while at it.

[PATCH 05/11] KVM: fix XSAVE bit scanning (now properly)

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 1463 bytes --]

From: Andre Przywara <andre.przywara@amd.com>

commit 123108f1c1aafd51d6a5c79cc04d7999dd88a930 tried to fix KVMs
XSAVE valid feature scanning, but it was wrong. It was not considering
the sparse nature of this bitfield, instead reading values from
uninitialized members of the entries array.
This patch now separates subleaf indicies from KVM's array indicies
and fills the entry before querying it's value.
This fixes AVX support in KVM guests.

[PATCH 06/11] wait: Provide __wake_up_all_locked

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 2422 bytes --]

From: Thomas Gleixner <tglx@linutronix.de>

For code which protects the waitqueue itself with another lock it
makes no sense to acquire the waitqueue lock for wakeup all. Provide
__wake_up_all_locked.

[PATCH 07/11] pci: Use __wake_up_all_locked pci_unblock_user_cfg_access()

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 932 bytes --]

From: Thomas Gleixner <tglx@linutronix.de>

The waitqueue is protected by the pci_lock, so we can just avoid to
lock the waitqueue lock itself. That prevents the
might_sleep()/scheduling while atomic problem on RT

[PATCH 09/11] slab, lockdep: Fix silly bug

[Steven Rostedt]

[-- Attachment #1: Type: text/plain, Size: 1669 bytes --]

From: Peter Zijlstra <a.p.zijlstra@chello.nl>

Commit 30765b92 ("slab, lockdep: Annotate the locks before using
them") moves the init_lock_keys() call from after g_cpucache_up =
FULL, to before it. And overlooks the fact that init_node_lock_keys()
tests for it and ignores everything !FULL.

Introduce a LATE stage and change the lockdep test to be <LATE.

[-- Attachment #1: Type: text/plain, Size: 3777 bytes --]

Ok, this is a nearly blind shot, but i was expieriencing strange idle time 
behaviour with this Ingo Molnar patch. The idle time was never incremented as 
read from /proc/stat for several minutes. The system itself was behaving fine
and had definetly not 100% load which was also verified with top.

I hadn't had the time to investigate further and my tests where with an ealier 
release with the Ingo Molnar Tasklet patch on top.

Hopefully i will find some time to test this stuff further but it will 
probably tuesday CET.

Best regards
Tim

Did some other time accounting increase instead ?

Must be either config related, or something got fixed meanwhile.

Hi

Yes, the other time seemed to be increasing normally.

I should also point out, that this phenomen was not always happening, but only 
sometimes and then again disapeared without any known reason.

Your emails seem to be damaged in interesting ways.

I assume the patch is going through the lockdep tree? If so, please make 
sure you include Christoph's ACK in the changelog.

This is for the stable-rt tree. This patch is on its way, but you'll
have to talk to Peter about Acks and such.

But this brings up a point. I'll start adding [RT] to the subject of the
patches as well to not confuse people.

Hmm, then are you sure that the tasklet patch causes the bug? Or perhaps
it only changes the timing to cause it. The bug may be without the patch
too.

May be patch is corrupted because it say this while patching:

patch -p1 <11.patch 
patching file drivers/acpi/ec.c
patching file drivers/acpi/internal.h
patch unexpectedly ends in middle of line

or just not fix this issue but problem steel present after this patch,
and seems i hit another one, i attach full dmesg.

Well, we are running the preempt rt patchset 3.0 since the rt-9 release and we 
have not seen this kind of error. It just started popping up after i applied 
the patch which i took directly from the mailing list when it was posted, 
since we had this ksoftirq issue especially after firmware update when ubifs 
has been updated.

The bad thing is that it is not happening deterministic but seemingly at 
random. But i will try your next prerelease and will report any results.

My patch is also not completly vanilla mainline. I am using the recomended 
patch from ubifs/master, some small platform patches and some timer patches 
Thomas Gleixner knows best about.

Best regards
Tim

Did this patch not make it into stable releases other than 3.1. I
couldn't find it in any other stable tress prior to 3.1.

Ah, this was done in the early stable-rt releases. Where we took
mainline fixes as long as they were in tglx's tree. But today the
stable-rt tree waits for mainline fixes to come in via the stable tree
so we don't do something like this. That is, miss getting a fix into
stable.  Yeah, this should be added to 3.0. (looks to be already in 3.2
and 3.4).


Greg,

Can you add the following commit to the 3.0 stable tree. We've had this
in v3.0-rt for some time now. :-/

Subject: [PATCH] intel-iommu: Fix AB-BA lockdep report

When unbinding a device so that I could pass it through to a KVM VM, I
got the lockdep report below.  It looks like a legitimate lock
ordering problem:

 - domain_context_mapping_one() takes iommu->lock and calls
   iommu_support_dev_iotlb(), which takes device_domain_lock (inside
   iommu->lock).

 - domain_remove_one_dev_info() starts by taking device_domain_lock
   then takes iommu->lock inside it (near the end of the function).

So this is the classic AB-BA deadlock.  It looks like a safe fix is to
simply release device_domain_lock a bit earlier, since as far as I can
tell, it doesn't protect any of the stuff accessed at the end of
domain_remove_one_dev_info() anyway.

BTW, the use of device_domain_lock looks a bit unsafe to me... it's
at least not obvious to me why we aren't vulnerable to the race below:

  iommu_support_dev_iotlb()
                                          domain_remove_dev_info()

  lock device_domain_lock
    find info
  unlock device_domain_lock

                                          lock device_domain_lock
                                            find same info
                                          unlock device_domain_lock

                                          free_devinfo_mem(info)

  do stuff with info after it's free

However I don't understand the locking here well enough to know if
this is a real problem, let alone what the best fix is.

Anyway here's the full lockdep output that prompted all of this:

     =======================================================
     [ INFO: possible circular locking dependency detected ]
     2.6.39.1+ #1
     -------------------------------------------------------
     bash/13954 is trying to acquire lock:
      (&(&iommu->lock)->rlock){......}, at: [<ffffffff812f6421>] domain_remove_one_dev_info+0x121/0x230

     but task is already holding lock:
      (device_domain_lock){-.-...}, at: [<ffffffff812f6508>] domain_remove_one_dev_info+0x208/0x230

     which lock already depends on the new lock.
