It's been two weeks, and the merge window for 2.6.38 is thus closed.
And an interesting merge window it has been.

This merge window saw the introduction of two of my favorite new features:

 - the use of group scheduling to give nicer interactive behavior in
the presence of "traditional" UNIX loads (ie terminal windows with
heavy loads like a "make -j8" or similar) by giving tty sessions
separate groups (the SCHED_AUTOGROUP config variable)

 - Nick's new (well, "new" - it's been brewing for a long time)
RCU-based path name lookup.

So the autogroup thing is really more of a technical gimmick than
anything else, but it really works very well for the kinds of things
it is designed for. If you still do "real work" in a terminal window,
you're likely to appreciate it. Compile in parallel in one window,
watch a movie in another, and the movie is really smooth. It can be
very noticeable indeed. It's not a panacea, but it's nice for what it
is.

The RCU-based name lookup is at the other end of the spectrum - the
absolute anti-gimmick. It's some seriously good stuff, and gets rid of
the last main global lock that really tends to hurt some kernel loads.
The dentry lock is no longer a big serializing issue. What's really
nice about it is that it actually improves performance a lot even for
single-threaded loads (on an SMP kernel), because it gets rid of some
of the most expensive parts of path component lookup, which was the
d_lock on every component lookup. So I'm seeing improvements of 30-50%
on some seriously pathname-lookup intensive loads.

So last cycle, we got rid of most of the BKL - which was really nice,
but practically speaking it was not a very important lock any more.
This cycle was different: Nick's series (and thanks to everybody else
who helped) really help a very real scalability and performance issue.
And we used to be rather good at pathname lookup before - now we're
just a whole lot better.

Now, those two are my personal favorites, but that's not to say that
you may care. Not all loads are all that name-lookup heavy, and the
scheduler auto-grouping may not matter for you. So to round the thing
up, we have a metric ton of other features, with drivers as usual
accounting for about half of the changes. The most noticeable part
during the merge window was the DRI updates, which caused some pain.
The most obvious fallout of that should all have been fixed, and we
should now have support for the AMD Fusion stuff along with some Fermi
acceleration support. And several updates to the Intel driver too.

But never fear. If you don't care about pathname lookup, scheduling or
graphics cards, I'm sure you can find changes to be excited about,
whatever your area of interest is. SCSI target infrastructure? Or all
the architecture updates (notably ARM and blackfin platform
additions)? Or just the sound and media drivers? Go look at your
favorite area in the git tree, I suspect it has gotten some love.

And as usual, report any regressions to the lists and the appropriate
authorities.

Oh, and it looks like mirroring from master.kernel.org is being very
slow, possibly at least partly because the conversion to
xv-compression seems to be going on (who knows - there's obviously a
script going over all the public files recompressing them from gz to
xz, but it may be some kind of dry-run and not final).

And I may also have managed to hit the weekly rsync "check
_everything_" window too. So rsync likely isn't just checking and
syncing new files, but checksumming every single file that gets
mirrored out and re-verifying it.

End result: it looks like git.kernel.org and the ftp mirrors are going
to take hours to update. So if you don't see 2.6.38-rc1 yet, and you
don't have an account on kernel.org and can fetch it directly from
master, don't worry. It will mirror out eventually, but it's going to
take some time.

Sit back, relax, and sip some foofy drink. It will all work out in the end.

I only do changelogs in the email if they are small enough to be
reasonable. -rc1 never is. -rc2 seldom is. Usually it's -rc3 and up.
In this case, even just the shortlog would have been about ten
thousand lines and 480kB, so it really isn't going to fly through lkml
(and nobody would read it all anyway)

But you can get git, and do

   git shortlog v2.6.37..v2.6.38-rc1

to get the shortlog. Or you can download the whole changelog from
kernel.org next to the kernel sources. The git approach is better,
because you can ask for the log for just specific files or
subdirectories that you are interested in, which turns the flood into
something much more manageable.

But, since you asked, we can just do

    git shortlog --author=justin v2.6.37..v2.6.38-rc1

which is appended. Go Justin!

               Linus

PS. No. I will not make personalized shortlogs for everybody who asks.

i wish i could do that for everything. i am pulling up to 500MiB every
-rc cycle and mostly codes for hardwares i don't have. not just that
sometimes changes to even pertain to my machine (so no, `git clone
--depth 1' is not what i have in mind).
it would be nice to have a module or a script for git that would work
with kconfig. so instead of pull-config-compile, one would
config-pull-compile. (ok some initial pull for kconfig stuff first but that
would be all). 
i asked this from folks at #git channel and they suggested, because
of the way git works, "git thinks in terms of trees not directories", i
should ask you to see if it's doable?
needless to say that this should also help with the load on kernel.org as
well, since i imagine people that pull from git to compile their own
kernel by definition don't need everything.

No you're not.

The *WHOLE* Linux kernel git archive fits in one 388M pack. That's not
some -rc release, that's the whole git history going back to 2.6.12 or
whenever it was that git was started (admittedly fairly well-packed,
but still). The incremental for some -rc cycle can be megabytes, but
we're still talking single megabytes, not hundreds of megs.

So no, you're not pulling 500MiB every -rc cycle, unless you're doing
something stupid like using http (which will trigger a re-fetch, since
I end up repacking a couple of times a release) or always re-cloning.

So the fix is not to try to fetch just a part - that will not work.
Exactly because git is so good at packing, doing silly hacks like
"--depth=1" actually fetches MORE data than just doing one clone once
and then pulling incrementally after that. And no, you can't just get
partial trees (although you can then try to save some disk space by
checking out only partial trees - it's not worth the pain, though).

So the fix is:

 - don't use http or rsync (they're fine for the initial clone, but
don't ever use it for any incrementals, and even then I'd suggest
keeping to rsync and not http)

 - if you have some firewall issue that means that you can only use
http, get the firewall fixed. It's not a git issue.

no need to fix git.

When pulling from 2.6.37 to 2.6.38-rc1, it should look something like this:

  remote: Counting objects: 84898, done.
  remote: Compressing objects: 100% (14274/14274), done.
  Receiving objects: 100% (71245/71245), 21.07 MiB | 26.53 MiB/s, done.
  remote: Total 71245 (delta 59086), reused 67779 (delta 56042)
  Resolving deltas: 100% (59086/59086), completed with 7395 local objects.

ie you got 21.07MiB for the whole change between 2.6.37 and 2.6.38-rc1.

(it does expand if you do it every day because then you won't be able
to delta quite as well, and the "completed with 7395 local objects"
means that the local packs will be much bigger on disk because they
will be expanded to have all the base objects, but that 21MB should be
the approximate actual network usage)

Considering that just the _diff_ between 2.6.37 and 2.6.38-rc1 is
about 42MB in size, the fact is that git is damn good at network
bandwidth.

Btw, what may confuse you a bit is that the on-disk representation of
the newly received pack ends up being about 69MB, ie the 21MiB of
network traffic almost tripled in size as a result of that "resolving
deltas" thing. That's because git pack-files are designed to always be
stand-alone, so on disk, the pack-file will always contain the base
objects needed to expand all the deltas.

But on the wire, we don't do that, which is why you have that
"Resolving deltas" phase - it's a purely local phase where it takes
the "pure delta" pack that came over the wire, and creates the
well-formed pack that doesn't have any deltas that depend on external
objects.

And that expansion will end up happening every time you pull: so if
you do daily pulls, all those pulls that will have been fairly small
on the wire will all have been expanded so that the resulting packs
are stand-alone. Which means that you often end up having the same (or
very similar) base objects duplicated in the packs.

So I can well imagine that if you do a pull every day, over two weeks
your .git/objects/pack directory will have new packs that together are
500MB in size due to all of that. That's why git likes doing some GC
on its data every once in a while - it will repack all those
individual packs into one big pack, which avoids all that duplication
of base objects.

And why do we expand the packs and make them stand on their own? Why
don't we just keep all the object data as deltas agains objects in
other packs, the way we pass data around on the network? The reason is
simply robustness. You can get into various nasty situations (like
circular delta dependencies) if you allow deltas between different
packs. So the only time we allow a so-called "thin pack" (ie the pack
is full of deltas against objects external to the pack) is for the
ephemeral pack that is transferred during a "pull" or "fetch". In that
situation we end up doing lots of extra sanity checking, and because
it's ephemeral you never get into the whole situation where deltas in
different packs could refer to each other (because by the time it's a
real pack, it will have been expanded out to be self-sufficient).

So do use "git gc" every once in a while to avoid unnecessary pack
duplication issues (it also makes object indexing much faster etc).

Hmm, reproduce it here with binutils-2.21.51.0.6-20110118
but not with GNU ld (GNU Binutils for Ubuntu) 2.20.51-system.20100908
I got this in system.map: ffffffff03514880 D jiffies_64, which looks
wrong.
looks binutils changed something again.
Have no idea, CC Lu Hongjiu.

.38-rc1 allyes64 bootup locks up soft, but first produces this lockdep splat:

That's probably one of these commits:

 563558b2c735: pps: add parallel port PPS signal generator
 46b402a0e5e4: pps: add parallel port PPS signal generator
 a10203c691ea: pps: add parallel port PPS client

Plus CONFIG_PPS_CLIENT_PARPORT=y.

This feature seems rather untested - this is a plain whitebox PC with a parallel 
port.

Btw., why does 46b402a0e5e4 and 563558b2c735 have the same title?

Thanks,

	Ingo

Either way... the whole jiffies vs jiffies_64 thing is kind of
ridiculous.  We should be able to do it in a completely
architecture-generic way by either making it a union(!) (with "jiffies"
and "jiffies_64" presumably would be #defines, or we do a global replace
across the tree), moving the variable declaration itself to a .S file
(which would only have data components and therefore would be
arch-generic) or doing something like the attached (untested since it is
1 am here) patch.

This should let us get rid of the hacks in *all* the architectures, not
just x86.

Ok - until it's resolved i'll queue up a revert - a known build failure is preferred 
to a boot regression.

Thanks,

Revert "x86: Make relocatable kernel work with new binutils"

This reverts commit 86b1e8dd83cb ("x86: Make relocatable kernel work with
new binutils").

Markus Trippelsdorf reported a boot failure caused by this patch.

The real solution to the original patch will likely involve an
arch-generic solution to define an overlaid jiffies_64 and jiffies
variables.

Until that's done and tested on all architectures revert this commit to
solve the regression.

There's a rather frequent, percpu related boot crash that I can see with .38-rc1:

Full bootlog and config attached.

One thing I've noticed is that CONFIG_MAXSMP=y, so it's pushing our various data 
structure limits. The crash signature itself seems to implicate NR_IRQS related data 
structures.

I'm quite certain that this is not related to x86 or irq changes in .38-1 - those 
were tested on this box rather well and this crash never triggered.

Thanks,

	Ingo

This is vfree() path used before local irq is enabled during early
boot.  vfree() triggered TLB flush (maybe debug enabled?) which used
on_each_cpu() which isn't quite happy to be called with local irq
diabled.

and this looks like alloc_percpu() failed earlier during early irq
init.  The irq init functions don't check for NULL return so it just
goes off later.  I'll see if I can reproduce the problem here.

It doesn't look like anything hardware dependent.  The first warning
seems more or less spurious and the GPF seems to be caused by earlier
memory allocation failure.  It's a bit curious that the allocation
failed on a x86_64 machine tho.

Thanks.

Not quite sure that to do about that though..

Is vmalloc() and vfree() supposed to work with interrupts disabled? I
always thought they weren't which would mean something in
pcpu_mem_alloc() needs changing...

I'm not sure about vmalloc(), but vfree() has been known to not work
with IRQs disabled for a long long while.

Looking at the code neither can work, since vmalloc() can end up calling
vfree(), what's curious though is that all the BUG_ON()s in there are on
in_interrupt() instead of for irqs_disabled().

Is alloc_percpu() supposed to work from atomic context?

Hello,

They aren't but percpu allocator doesn't call them with interrupts
disabled normally.  It only happens during early boot before it's
enabled for the first time but this is an allowed exception.  We'll
probably need to update the WARN_ON to consider the rare call path.
It also looks like something in that path is turning off/on IRQ
instead of saving/restoring it, so that probably needs to be changed
too but both aren't really critical.

I think the real problem is a lot of unsigned int percpu allocations
added by 6c9ae009 (irq: use per_cpu kstat_irqs).  percpu allocator
should be able to cope but it assumes that it would always be able to
allocate contiguous allocation map using vmalloc and that might be
failing, although I cannot readily see how or why that would happen
frequently on a 64bit machine.

Thanks.

When I first started using git (2006?) I was recommended to use "-k"
when doing a fetch or pull. I don't even remember why it was
recommended. I still do it, but is it necessary?

All the help says is:

       -k, --keep

That's a different issue. That marks the resulting pack for "keeping",
which means that it won't participate in garbage collection.

IOW, it's a bad idea.

There _is_ a reason for it, namely that if your machine is really
slow, you may want to mark big packs for keeping, so that when you do
a gc it will be cheaper to do. In particular, the initial clone/fetch
may well be worth marking "keep". But even that is really only worth
it if you have such a slow machine (or the machine has too little
memory) that repacking is really a big pain (it's not like you need to
do gc very often - once a week would be overkill for most projects).

(There can be other reasons to mark packs as "keep" - namely to help
with http/rsync of the resulting archive if you have a huge amount of
history. In that case, it might be worthwhile keeping historical data
as a "keep" pack, so that rsync/http don't need to re-fetch it after a
GC or repack event.)

Btw., based on Peter's suggestion i tried the limit-bumping hack below - but it did 
not help, the crash still triggers on 5%-10% of all randconfig bootups.

Its actually looking pretty good (as is -next from it). The -next one
I've been beating up pretty hard today rescuing a box with a drive fail.

The i915 driver is busted on my main box but the underlying breakage seems
older so for the moment I'm cautious of treating it as a recent
regression as 2.6.32 is the newest that seems totally reliable of
2.6.32/5/7/8rc1

Only oddity is the kmemleak report is reporting a few possible leaks and
suggesting I look in the sysfs file .. which isn't there ???

I'm now running tests with MAXSMP forcibly disabled - and there are no crashes after 
69 randconfig iteration. Before it would crash within 10 iterations.

So it seems the MAXSMP sizing tests triggers a new percpu regression.

Kernel build script should check known broken linkers

Same thing here on x86_64 with Binutils 2.21.0.20101217. Boot stops
after "Booting the kernel" message, regardless of whether
CONFIG_RELOCATABLE is set or not.

System.map has
ffffffff02c92880 D jiffies_64

Reverting the patch also solved the problem for me.

It needs CONFIG_DEBUG_PAGEALLOC to trigger. As the comment in 
vmap_debug_free_range() already says "it's going to be slow" I wonder if 
we could just hack around the problem by adding a

   if (!irqs_disabled())

guard around the debugging code to make vfree() always work with IRQs 
disabled.

That won't be sufficient, __purge_vmap_area_lazy() needs to call
flush_tlb_kernel_range() occasionally.

There really is a good reason vmalloc()/vfree() don't work with
interrupts disabled.

During early boot, local IRQ is disabled until IRQ subsystem is
properly initialized.  During this time, no one should enable local
IRQ and some operations which usually are not allowed with IRQ
disabled, e.g. operations which might sleep or require communications
with other processors, are allowed.

lockdep tracked this with early_boot_irqs_off/on() callbacks.  As
other subsystems need this information too, move it to init/main.c and
make it generally available.  While at it, toggle the boolean to
early_boot_irqs_disabled instead of enabled so that it can be
initialized with %false and %true indicates the exceptional condition.

percpu may end up calling vfree() during early boot which in turn may
call on_each_cpu() for TLB flushes.  The function of on_each_cpu() can
be done safely while IRQ is disabled during early boot but it assumed
that the function is always called with local IRQ enabled which ended
up enabling local IRQ prematurely during boot and triggering a couple
of warnings.

This patch updates on_each_cpu() and smp_call_function_many() such
on_each_cpu() can be used safely while early_boot_irqs_disabled is
set.

Hello, guys.

These two patches remove both warnings.  The first warning was
completely spurious.  The second lockdep one was triggered by
on_each_cpu() enabling local IRQ too early.

I don't think percpu allocator itself malfunctioned.  There was no
allocation failure.  It whines when percpu allocation fails but didn't
in the log.  Other than calling vfree() early triggering the above
condition, it worked okay.

So, it's either the early enabling of local IRQ by on_each_cpu()
breaking something in the IRQ subsystem or something different.  Ingo,
can you please see whether these two patches cure the panic too?

Thanks.

Hmm, I would try to increase PERCPU_DYNAMIC_RESERVE, or pcpu_mem_alloc()
could try to use kzalloc() even for allocations bigger than one PAGE,
and fallback to vzalloc().

We have more alloc_percpu() uses, we also should try to use first chunk
if possible.

It already handles all those stuff.  As I wrote in the other message,
I don't think this problem has much to do with percpu allocator
itself.

> if possible.

Yeah, but that's true.  It's probably too small at this point.  Maybe
there should be a way to monitor percpu memory status, a proc entry or
something so that we can have more data on sizing.

Why not use something like: system_state != SYSTEM_RUNNING ?

Please try hpa's patch in this thread on top of very latest (today's) -git or latest 
-tip:

   http://people.redhat.com/mingo/tip.git/README

Does that result in a booting system? That way we can avoid most of the linker

Cuz, it's finer grained than that.  We can add a SYSTEM_* flag but I
wasn't sure whether that would be just creating more noise.  If we try
to consolidate these things, we probably should consider
oops_in_progress too.  It probably is a good idea but let's first fix
the problem at hand.

Thanks.

Yup, SYSTEM_RUNNING happens much later in the boot sequence so we
don't want to use it here. We had a long discussion about system_state
when we introduced gfp_allowed_mask and IIRC people wanted to avoid
more system_state flags and preferred more explicit ones like
early_boot_irqs_disabled.

We can do more cleanups later but for the problem at hand:

Acked-by: Pekka Enberg <penberg@kernel.org>

for both patches.

Right, no problem with that, I was just wondering why you'd add an extra
variable instead of using the system states.

this patch causes an allmod64 build failure:

(.init.text+0x741): undefined reference to `early_boot_irqs_off'

They seem to help with the MAXSMP config that crashed yesterday.

I'll be able to do more testing and see whether the bug is really fixed once the 
modular kernel build failure is fixed.

During early boot, local IRQ is disabled until IRQ subsystem is
properly initialized.  During this time, no one should enable local
IRQ and some operations which usually are not allowed with IRQ
disabled, e.g. operations which might sleep or require communications
with other processors, are allowed.

lockdep tracked this with early_boot_irqs_off/on() callbacks.  As
other subsystems need this information too, move it to init/main.c and
make it generally available.  While at it, toggle the boolean to
early_boot_irqs_disabled instead of enabled so that it can be
initialized with %false and %true indicates the exceptional condition.

* The original patch missed conversions of several users causing build
  failures.  Updated.

Sorry about that.  Here's the updated patch.  The second one doesn't
need to be changed.

I'm investigating this. Thanks for the report!

Well, 46b402a0e5e4 refers to version 6 of my patchset and 563558b2c735
is a diff between version 6 and 7. I've seen from the e-mails from
Andrew that I received that he added both patches and then folded the
latter into the former. The same thing happened with several other
patches but only these two sneaked in. Maybe this is a bug in the
software (quilt?).

Please try hpa's patch in this thread on top of very latest (today's) -git or latest 
-tip:

   http://people.redhat.com/mingo/tip.git/README

Does that result in a booting system? That way we can avoid most of the linker

lockdep: Move early boot local IRQ enable/disable status to init/main.c

During early boot, local IRQ is disabled until IRQ subsystem is
properly initialized.  During this time, no one should enable
local IRQ and some operations which usually are not allowed with
IRQ disabled, e.g. operations which might sleep or require
communications with other processors, are allowed.

lockdep tracked this with early_boot_irqs_off/on() callbacks.
As other subsystems need this information too, move it to
init/main.c and make it generally available.  While at it,
toggle the boolean to early_boot_irqs_disabled instead of
enabled so that it can be initialized with %false and %true
indicates the exceptional condition.

smp: Allow on_each_cpu() to be called while early_boot_irqs_disabled status to init/main.c

percpu may end up calling vfree() during early boot which in
turn may call on_each_cpu() for TLB flushes.  The function of
on_each_cpu() can be done safely while IRQ is disabled during
early boot but it assumed that the function is always called
with local IRQ enabled which ended up enabling local IRQ
prematurely during boot and triggering a couple of warnings.

This patch updates on_each_cpu() and smp_call_function_many()
such on_each_cpu() can be used safely while
early_boot_irqs_disabled is set.

re-cloning to reclaim disk space. but disk space is not the only thing;
i can compile a tar release all in ram (1G) but re-cloning 388M into a
build directory there is a no go.

Hmm, a slightly modified version of the reverted patch works here for
both 32/64 bit kernels and with old/new binutils too. Maybe we can use
it currently till we remove the link script trick?

Well, I only see that there could be a problem with parport's
waitlist_lock because it is used:
 * in parport_claim which can be called from an irq handler
 * in parport_unregister_device without disabling interrupts

But parport_unregister_device should probably never be called while
parport interrupts are enabled (in hardware). So this is a false
positive. Is this right?

But I also see here that there is probably a contention for the port
between ppa and pps_parport. So maybe I shouldn't use
parport_claim_or_block because it blocks forever and therefore can
lock up the thread that loads the module. It's strange however that
this function is used in lots of other modules without trouble.

Can you please check if the lockup is caused by parport_claim_or_block
in pps_parport/pps_gen_parport? I built 2.6.38-rc1 kernel with
allyesconfig but it locks up long before pps_parport gets loaded.

OK, this is just messed up.  If we need jiffies in a special section
then we should declare it as such (see __jiffy_data), but it's not clear
to me why we would.  This seems like hack upon hack.

However, I suspect we may want to put jiffies into a .S file, and that
.S file needs to take into account architectures which need underscore
prefixes (which really sucks to have in ELF and is a major fail on those
ABI designers...)

It's a debugfs file; the log assumes you have debugfs mounted at

"Enabled in hardware" is immaterial - with shared interrupts, it
doesn't matter one whit whether parport interrupts are disabled on the
chip, because some other chip may be using the same interrupt line.

So you'd need to have something that guarantees that there is no
concurrent use, like actually unregistering the irq handler itself.
Things like that can work.

HOWEVER, even then I think you should see the lockdep message as a
problem. The automated toolchain is great because it shows problems
that it thinks might happen - not when they happen, but based on a
simpler theoretical model. Ignoring the error because there is some
rule in place that is hard to explain to the automated toolchain is
the wrong thing to do, because it makes the lockdep automation less
reliable.

Think of it as a compiler warning - maybe the warning doesn't actually
imply an actual bug, but you should strive to write code that doesn't
warn, because otherwise the noise from the warning you ignored will
make it harder for others to see the _real_ bugs.

Yeah. Also, inevitably the false positives have a higher likelyhood
of making it into a released kernel, often because the bugs where
there was a real lockup as well got noticed via other means.

It's similar with compiler warnings as well: the questionable ones where
GCC is wrong or at least confused accumulate.

Also note that here there's a real lockup here as well, shortly after the lockdep 
message - the boot never continues, the box keep spewing the PPS debug messages:

[   76.240020] pps pps0: PPS event at 4294911356

I think that pulling from kernel.org became slower too. (not sure
exactly when but probably since about a year).

When I run git pull, it just sits there for a long time, with no visible
network/disk I/O, and only after that it starts the "remote: Counting
objects" phase.
I just tried to measure that time and it is ~12s now, which is not that
bad, but I remember that I even had to wait minutes to see the "Counting
objects" phase in December.

Is it because git on the server side needs to figure out which objects I
already have and which I don't? But I thought thats part of the
"Counting objects" phase, so what happens before that, and why are there
no progress messages about it?

Best regards,
--Edwin

parport_unregister_device should never be used when interrupts are
enabled in hardware and irq handler is registered so there is no need
to disable interrupts when using waitlist_lock. But there is no way to
explain this subtle semantics to lockdep analyzer. So disable interrupts
here too to simplify things. The price is negligible.

Small detail: please use a consistent coding style, i.e. 'spin_lock_irq(', not 
'spin_lock_irq ('.

I think I was able to reproduce the lockup by compiling parport,
parport_pc, pps_parport and pps_gen_parport into the kernel. Both
pps_parport and pps_gen_parport use parport_claim_or_block() to claim
the parallel port. They compete for the parallel port at bootup. One
of them gets it. The other one then lockups the system.

After reading the docs I decided to just add PARPORT_FLAG_EXCL and it
worked. The patch follows. Does it help with the lockup you experience?

Both pps_parport and pps_gen_parport are written in a way that they
can't share a port with any other driver. This can result in locking up
the process that loads modules or even the whole kernel if the modules
are compiled in. Use PARPORT_FLAG_EXCL to indicate this.
