2.6.21-mm1

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.21/2.6.21-mm1/


- Added the git-battery tree to the -mm lineup (Anton Vorontsov
  <cbou@mail.ru>).  It presently generates mysterious depmod error messages.

- The staircase CPU scheduler was dropped




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.

__must_check was added to mutex_lock_nested() which returns void. This
causes the following warnings:

OK, thanks.  I assume that's a Kconfig mistake in the wireless tree.

But it looks like a real minefield:


+static inline void b44_pci_exit(void)
+{
+#ifdef CONFIG_B44_PCI
+	ssb_pcihost_unregister(&b44_pci_driver);
+#endif
+}

and

+#ifdef CONFIG_BCM43XX_MAC80211_PCI
+	ssb_pcihost_unregister(&bcm43xx_pci_driver);
+#endif

and

+#ifdef CONFIG_SSB_PCIHOST
+/* PCI-host wrapper driver */
+extern int ssb_pcihost_register(struct pci_driver *driver);
+static inline void ssb_pcihost_unregister(struct pci_driver *driver)
+{
+	pci_unregister_driver(driver);
+}
+#endif /* CONFIG_SSB_PCIHOST */


That looks waaaaaay more complicated than it needs to be.

I'm thinking that the first two ifdefs should be removed and that third one
needs a #else clause which implements stubs and that b44 Kconfig needs to
be taught about CONFIG_SSB_PCIHOST in some fashion.

Or something like that.

config B44_PCI
	bool "Broadcom 4400 PCI device support"
	depends on B44 && NET_PCI

We simply need a SELECT SSB_PCIHOST here. Not sure why it's not there.
I thought it used to be there.

That may have only been applied to the mm-master branch, which now
no longer exists.  I'll patch it now.

Then please revert the "fix" to match_table_t...

There is no reason for something like the nfsroot parser to be kept in
memory after the system has booted. That would be code bloat.

Alternatively, please change the nfsroot parser to use

        static struct match_token tokens[] __initdata = {

That is in any case cleaner than using a typedef.

It makes little or no sense to be forcing attributes like 'const' in a
typedef. That is basically stating that it is inconceivable to use
anything else. Clearly not the case here...

Yeah.  I think that there shouldn't be a typedef.  There's no real need for
it.

Bah, that was hidden from my allmodconfig because CONFIG_UNIONFS is inexplicably
dependent upon CONFIG_SLAB.

How come?

As it was discussed a while back on the mailing lists, Unionfs is trying to
be smart and tries to do reallocation on its own. The way it does it makes
it depend on some internals of the SLAB allocator. There have been some
patches out there for a realloc function (by Pekka Enberg, IIRC), but as far
as I can tell, they haven't been merged in.

krealloc should be in mainline within a couple of days.

I think Adrian added it before we introduced krealloc() to fix uniofs
from poking slab internals.

I believe the (commented out) patch in -mm series file fixes things:

	unionfs-fix-slab-abuses-with-krealloc.patch

It probably got commented out when unionfs got temporarily dropped from -mm.

The price might drop to $100 in a few years.

But currently, a more reasonable name might be "$175 laptop".

Let's simply call it "OLPC laptop" without any price tag.

'make silentoldconfig' produces:

SCSI debugging host simulator (SCSI_DEBUG) [N/m/y/?] n
ESP Scsi Driver Core (SCSI_ESP_CORE) [N/m/y] (NEW) ?

Sorry, no help available for this option yet.

ESP Scsi Driver Core (SCSI_ESP_CORE) [N/m/y] (NEW) 

and grovelling around inside origin.patch find a nicely done driver calling
itself esp_scsi[ch].  Unfortunately, the only hint as to what devices this
applies to (or whether it's in fact a new driver *CORE*, similar to the
recent FireWire and mac80211 driver core rewrites), is found in this array:

static const char *esp_chip_names[] = {
       "ESP100",
       "ESP100A",
       "ESP236",
       "FAS236",
       "FAS100A",
       "FAST",
       "FASHME",
};

I'm presuming some Kconfig help will land before the 2.6.22 merge window
closes? :)

Sorry. I didn't check CONFIG_ACPI=n. The acpi header file inclusion
is too complicated.

Below patch against 2.6.21+gregkh-pci-pci-reduce-aer-init-error-information.patch
fixes the compiling issue. I delete the acpi header file inclusion in aerdrv.h,
and move function aer_osc_setup to another file.

I tested it with both CONFIG_ACPI=y and CONFIG_ACPI=n.

It seems that we should goto 'out_free_table' if an error happens in
the mainloop. Otherwise 'details' is passed to restore_files() without
being initialized.

Good catch. The patch is wrong, though. Wwe must restore the file 
descriptors in case revoke fails; otherwise we'll leave non-revoked files 
hanging. The proper fix is to move initialization before the 
do_each_thread() bit. Care to make a new patch, Frederik?

We have following code:
/* guarantee that calls that happen before init will not find a channel */
static struct chan_ref_percpu __initdata null_chan_ref[NR_CPUS];

static struct chan_ref_percpu *channel_table[] = {
	DMA_TX_ARRAY_INIT(null_chan_ref)
};

The DMA_TX_ARRAY_INIT is some macro obscufation that serves no
real use and just hide a few assignements.
What happens here is that we assign channel_table a value
that are used as cover-up until the real assignment happens
in the init function.
So the only real way to fix this seems to remove the otherwise correct
__initdata mark on null_chan_ref.
Thats one pointer wasted pr. cpu (in total NR_CPUS).

Not sure if there is a better way to do this, but I went ahead and added
a global flag that gets set after init.  It also lets DMA_TX_ARRAY_INIT
go away, but it adds another branch to the fast path.

On i386 binutils fails to pick up reference to kernel_init
in the:
   kernel_thread(kernel_init, NULL, CLONE_FS | CLONE_SIGHAND);
line from rest_init in init/main.c

Wy binutils throw away the info about the kernel_init symbol
is beyond me.
A workaround is to simply declare kernel_init non-static.

This is because:
static struct notifier_block thermal_throttle_cpu_notifier =
{
	.notifier_call = thermal_throttle_cpu_callback,
};

thermal_throttle_cpu_notifier is not marked __initdata
but thermal_throttle_cpu_callback is __cpuinit.
So this is a bug.
I do not see it with my config (a slightly modified defconfig)
so I cannot test it.
Could you try to change the line to:
static struct notifier_block __cpuinitdata thermal_throttle_cpu_notifier =
And check if this makes the warning go away.

We have kthread that calls kthreadd_setup - the latter marked __init.
The only user of kthreadd is init/main.c:rest_init() but I do not know
enough about the kernel boot process to say if it is OK to mark
kthreadd __init (that would be my fist proposal).

Andrew or anyone?

It comes from this code (mm/slab.c):
/*
 * For setting up all the kmem_list3s for cache whose buffer_size is same as
 * size of kmem_list3.
 */
static void __init set_up_list3s(struct kmem_cache *cachep, int index)
{
	int node;

	for_each_online_node(node) {
		cachep->nodelists[node] = &initkmem_list3[index + node];
		cachep->nodelists[node]->next_reap = jiffies +
		    REAPTIMEOUT_LIST3 +
		    ((unsigned long)cachep) % REAPTIMEOUT_LIST3;
	}
}

It is supposed to be used only during early init and thus marked __init.
And initkmem_list3 is marked __initdata so that matches.

But set_up_list3s() is used outside __init marked functions and thus result in an error.

I do not know how to fix this.

Yes, this is one of those rare places which triggers a warning but where no
changes are needed.

I'm thinking that we could address this with a new section __nowarn and
__nowarndata (or whatever).  These will have the same behaviour as regular
.text and .data, only the symbol-checking tool would know about them and
would suppress the warnings.

Perhaps there's some other way of communication this information from the C
level down into the checker - I haven't thought about it much.

The current approach is to rely on symbols being proper resolved but binutils
are playing tricks and does not always provide info to resolve static symbols.
Originally I thought this was pure inlining issues but it seems to be more than
that.
But introducing a special section just to say "references to .init.text" is OK
seems like a bit of overengineering to me.
I will give it a try during the coming week.

Looks like a locking error in the DVB code.

Actually, kernel/module.c:__symbol_get() does
spinlock_irq_save(&modlist_lock) and then calls use_module().

But when CONFIG_MODULE_UNLOAD=y, use_module() wants to
sysfs_create_link() (I wonder why) which will clearly blow up.

Ah, at first I thought you had CONFIG_MODULE_UNLOAD=y for 21-mm and =n
for 21-git which is why you weren't able to reproduce this on 21-git.
But on checking I found 21-git has a different __symbol_get which
calls strong_try_module_get(owner) directly and not use_module().
Perhaps Andrew missed this patch?

OK, thanks.

What appears to have hapened is that Trent's not-yet-in-mainline
add-ability-to-keep-track-of-callers-of-symbol_getput.patch assumes that
use_module() is atomic, but Kay's now-in-mainline
gregkh-driver-sys-modules-holders.patch concurrently assumed that
use_module() is not atomic.

But use_module() already had a GFP_ATOMIC allocation in it, which tends to
indicate that sticking a sysfs_create_link() into use_module() wasn't an
appropriate thing to do.

gargh.  Could we please have some statement regarding use_module()'s
caller-provided environment and locking expectations?

[BUG] mixing 8250/16550 and AT91 serial ports causes oops

I tracked down my oops. It looks to be a problem with mixing 8250/16550
serial ports and the AT91 ports on the Atmel AT91SAM9260-EK board. Here is

Mess.  Someone incorrectly called the IO scheduler under a spinlock (or
similar), CFQ tried to do a dump_stack(), but the dump_stack() code
exploded.  Usually this happens when the x86_64 tree contains stacktrace
improvements, but the unwinder (at least) wasn't present in -mm1.

How come those addresses are 0xb0......, btw?  You're running a different
vm split?

4k stacks, I will try to reproduce it with 8k stacks - which shouldn't be hard (see below).

It will take a while, I need to boot to a good kernel so unattended DVB-T recording works 
reliably, I'm assuming switching to a different IO scheduler will avoid any problems for

continued compiling the kernel after sending that email so reproducing it should be easy.

Oh, OK, in that case it is perhaps a genuine stack overflow.

That's not good.

Please enable 8k stacks before doing any other debugging things, see if
that fixes it.

I've found that XFS+lvm+4k stacks is completely unusable with current
kernels.  I get hangs/oopes after ~10mins of work.  I'm using wli's 8k

Sounds like this is new behaviour?

Whoa. The verdict is usually "don't use so much stack".

Do we know what has gone wrong here?

Last week Jens said he was picking up the ancient
md-dm-reduce-stack-usage-with-stacked-block-devices.patch, but he doesn't
seem to have done so yet.

XFS is frequently implicated.

Well, the culmination of those patches is a patch to use vmallocspace
to establish guard pages for stacks so overflows are immediately trapped
and the potential for silent corruption greatly reduced. That would be
where I suspect it's most relevant, as that's the focal point of the
series. The bit about unconditional IRQ stacks arose as part of review.

It started life as a set of patches intended to help with debugging
stack overflows, which is how the only tangentially-related unconditional
IRQ stacks came about: originally they were optional as a debug option
for differential diagnosis of interrupt-time overflows. For mainline, hch
suggested that they should rather be made unconditional.

The third part of the series that survived review was dynamic boot-time
allocation of IRQ stacks, which was originally motivated by the need
for indirection when remapping IRQ stacks into vmallocspace, but also
served the purpose of mitigating space overhead when using IRQ stacks
because cpu_possible_map is not set up as it should be to avoid the
allocation via per_cpu array variables' dynamic boot-time allocation
on i386 and (AFAIK) x86-64.

I planned to merge them partially. Add the separate 4/8/irqstack options,
add the vmalloc support, but not support the > 8K stacks. Haven't yet.

I respun things to incorporate some of hch's suggestions and to fix
an issue Jeremy Fitzhardinge had with CPU hotplug, and some suggestion
from someone else, too.

Basically what changed was:
( 1) drop the large stack config option patch entirely
( 2) fold the __pa() check into the vmalloc stack patch under #ifdef
( 3) rename CONFIG_VMALLOC_STACK to CONFIG_DEBUG_STACK
( 4) fold guarding CPU 0's IRQ stack into the vmalloc stack patch
( 5) make IRQ stacks unconditional instead of independently configurable
( 6) check slab_is_available() for CPU 0's bootmem vs. get_free_pages()
( 7) mark various things __cpuinit that needed to be
( 8) handle and propagate allocation errors up to __cpu_up()
( 9) redo CPU 0's IRQ stack allocation to normalize it for hotplug
(10) use a struct for IRQ stack state instead of 3 per_cpu vars

The current patch series needs the two fixup patches at the end folded
back into the patches it fixes up, but follows in its entirety as a
series of MIME attachments. I've no idea what it applies against.

Subject: dynamically allocate IRQ stacks

Dynamically allocate IRQ stacks in order to conserve memory when using
IRQ stacks. cpu_possible_map is not now initialized in such a manner as
to provide a meaningful indication of how many CPU's might be in the
system, and features to appear in the sequel also require indirection,
so they themselves are not allocatable as per_cpu variables, but rather
only pointers to them.

IRQ stacks are a valuable stability feature. This patch makes them
unconditional, as there is no circumstance under which they do not
improve stability and they have no meaningful performance impact.

This patch introduces CONFIG_DEBUG_STACK, which vmalloc()'s task and IRQ
stacks in order to establish guard pages. In such a manner any stack
overflow that references pages immediately adjacent to the stack is
immediately trapped with a fault, which precludes silent memory corruption
or difficult-to-decipher failure modes resulting from stack corruption.

It furthermore adds a check to __pa() to catch drivers trying to DMA off
the stack, which more generally flags incorrect attempts to use __pa()
on vmallocspace addresses.

I've only recently started using xfs, so I couldn't say if its new
behaviour.  I did notice that it took a week or so for problems to set
in; my theory is that as the filesystem got a bit aged, its
datastructures got a bit more complex, and cause the kernel code to use
more stack.  But that's just a guess.

The worst case stack usage through XFS occurs when it has to read
metadata blocks in the writeback path when doing an allocation
transaction. This happens when walking the freespace btrees looking
for an extent matching the allocation requirements. As the fileystem
fills up, these btrees will grow and you are more likely not to have
a block inthe btree cached in memory.

So yes, this is a possible reason you hadn't seen any problems early
on.

FWIW, there's also been recent reports of both ext3 and reiser on
LVM blowing 4k stacks, so if you use LVM it probably advisable to
go back to 8k stacks....

Cheers,

Dave.

FWIW, I run dm-crypt+xfs on one machine, of course with 8k since that's
suse default. No issues. dm-crypt and lvm got something in common,
don't they?

For new config variables that were introduced, I set them to 'default y'
so when upgrading from an older .config, it does not deselect the drivers
_inside_ the new menuconfig. People who have CONFIG_MAC_EMUMOUSEBTN=y
will magically get it set to =n because MACINTOSH_DRIVERS is not y.

Whether you need macintosh on i386... oh well, ask someone who knows.
Fact is, that at least SUSE has CONFIG_MAC_EMUMOUSEBTN=y but I
wonder wtf for.

I had a similar suspicion that something else requires the default=y things ...

Well, this is clearly wrong since it is only for a mac, single-button, mouse,
IMHO.  Look for CONFIG_MAC_EMUMOUSEBTN in drivers/char/keyboard.c

Re: 2.6.21-mm1

The SLUB code introduces the config segment below to stop SLUB being
used on powerpc:

    config ARCH_USES_SLAB_PAGE_STRUCT
       bool
       default y
       depends on SPLIT_PTLOCK_CPUS <= NR_CPUS

However as far as I can kconfig has no support for operators other than
==, !=, &&, and ||.  Who can say why we do not get an error.

Cirtainly in my testing this simply never triggers and bad kernels result.

Thoughts?

Get rid of the whole patch as soon as possible? It seems that PPC work is

Thanks for working that out - it helps heaps.

x86_64-mm-cpa-kerneltext.patch seems to have been dropped from Andi's tree.

I the most recent version of the patch I sent to Andi this line is gone (again),
as I realized it was wrong on i386 (namely for DEBUG_PAGEALLOC) and its

Yes the version of the patch that went into Linus' tree doesn't have it.
Does the problem happen with mainline gitLATEST too?

Andi,

Latest git is OK with qemu, I'll test it on a real machine tonight.

x86_64 UP Athlon64 I get a crash on boot using SLUB.  Switching to SLAB 
makes it go away.  I don't have a serial console, so the best I have is 
a digital photo of as many lines as my VGA console was able to get (60 
or so).  Is there a better way to capture the oops output so that the 
full trace canbe seen?

config and dmesg from working SLAB configuration (broken when switched 
to SLUB):

It fails to create a slab. There should be some of message above what I 
can see that would indicate what went wrong.

Please try to reboot and specify "slub_debug" as a kernel parameter. If it 
boots then send us the kernel log output. Must have something to do with 
how the scsi slab is created in scsi_setup_command_freelist.

The first 8 bytes of the freed object were overwritten.

Here are some potential candidates that have recently handled the object. 
That was less than a jiffy ago. So very recent.

Not having any idea what I'm doing, I looked at cryptomgr_probe and 
cryptomgr_notify, and can't seem to see much, except for the following 
odd lines.

 From cryptomgr_schedule_probe, which is almost certainly inlined into 
crypto_notify:

-----

param = kzalloc(sizeof(*param), GFP_KERNEL);
...
param->thread = kthread_run(cryptomgr_probe, param, "cryptomgr");
if (IS_ERR(param->thread))
    goto err_free_param;

    return NOTIFY_STOP;

err_free_param:
        kfree(param);
err_put_module:
        module_put(THIS_MODULE);
err:
        return NOTIFY_OK;

-----

while cryptomgr_probe does (with a local variable param that points to 
the same data):

-----
...
if (err)
    goto err;

out:
    kfree(param);
    module_put_and_exit(0);
-----

Now perhaps I am wrong, but would it be possible for the kthread_run() 
call to cause cryptomgr_probe to run before the return result is stored 
into param->thread?  That would mean that param would be accessed after 
freeing.

<changes thread to a local variable in the cryptomgr_schedule_probe 
method...compile...test...still fails>

I guess that's not it.

Any thoughts on what might be the cause of this (I've added Herbert Xu 
to the CC list since he seems to be the crypto maintainer)?

I'll try to add some printk's in there to see if that enlightens me.

Thanks for reporting this.  This patch should fix the problem.

I see that this patch made it in to mainline, and latest -git now
works for me, so I assume this was the correct solution.  I thought I
had tried this exact change without success when I was looking at the
problem, but I guess I did something wrong along the way.

Thanks for the fix,
Kevin

Hum,
I'm running git 705962cc (which is a commit after -rc1) and I still see
the OOPS on boot. The patch above is already applied though. Note that
I'm using the SLAB allocator:

CONFIG_SLAB=y
# CONFIG_SLUB is not set
# CONFIG_SLOB is not set

Are you sure you're actually running 2.6.22-rc1? Due to a bug
in the padlock patch present in 2.6.22-rc1 it shouldn't be
possible to select ALGAPI as a module.

Cheers,

Well, pretty sure. The OOPS says 2.6.22-rc1-libata-g705962cc-dirty,
git agrees and I've done a full rebuild. The .config is generated
using 'make oldconfig' using the 2.6.21 as baseline, maybe ALGAPI is
coming from there?

Sorry, my mistake.  That bug only happens if you have padlock turned on.

Anyway, if possible could you post the complete dmesg when it crashes?
I'd like to see what has happened up to the point where it crashes.

Thanks,

Output from serial console is enlightening (sort of...):

Loading IPsec SA/SP database from /etc/ipsec-tools.conf: BUG: unable to
handle kernel paging request at virtual address 6b6b6ceb printing eip:
b0141aef
[oops]

Problem is that:
- /etc/ipsec-tools.conf is empty (everything is commented out), it's
  a leftover of previous experiments.
- AH and ESP are disabled in the kernel since I don't use them anymore.

Removing setkey script from init.d makes the OOPS disappear though;
nothing happens if I manually run setkey after the boot...

This is the full log:

module_put() is trying to decrease the refcount of a module that's
already been freed, AFAICT.

Thanks.  Turns out to be a silly bug :) It's been around for a while
though.

[CRYPTO] api: Read module pointer before freeing algorithm

The function crypto_mod_put first frees the algorithm and then drops
the reference to its module.  Unfortunately we read the module pointer
which after freeing the algorithm and that pointer sits inside the
object that we just freed.

So this patch reads the module pointer out before we free the object.

Thanks to Luca Tettamanti for reporting this.

It seems that build system was confused... I've checked the timestamps
of *.o files and make didn't rebuild anything, but rebuilding after a
'make clean' did "fix" the problem. Sorry for the noise...

Ok, wait: it's still there. It's just not 100% reproducible, sometimes
the system boots fine. So it either crashes on boot or it runs fine
for hours.

There is more... The above describes the repair actions that were taken by 
SLUB. Poison was restored and then the slab was taken out of circulation 
since pointers may still exist that may damage additional objects if used 
to store more data.

It seems that a uevent notification fails.

This change breaks the display on an ibook1 with 800x600 lcd.
It is commit b4e124c138558a0cff51398ddff9a8e44ed0b529 in 2.6.22-rc4.
The used config is arch/powerpc/configs/pmac32_defconfig

It seems that the recognized display width is only 640, the remain space
up to 800 is repeated with the content from colum 0. The chars around
colum 640 are mostly garbage.

Are you sure? I would expect
atyfb-halve-xclk-with-mobility-and-32bit-memory.patch to cause more
problems.

This seems to confirm my suspicion.

Please try this patch:

This oneliner fixes it for me.

Strange. Either patch alone should not cause any change in the clock
frequencies. Combined the two and it should lead to exactly the dmesg
you posted.

Here's a slightly safer version, just in case there are iBooks with
non-mobility chips or using the 64bit memory interface.


atyfb: Fix XCLK frequency on Apple iBook1

Fix a regression on Apple iBook1. Changes in the clock init code
caused an incorrect XCLK frequency to be used leading to a corrupted
display.

Yes, this one fixes it too.
