unregister_ioctl32_conversion and modules. ioctl32 revisited.

unregister_ioctl32_conversion and modules. ioctl32 revisited.

[Andi Kleen]

Hallo,

There seems to be an unfixable module unload race in the current
register_ioctl32_conversion support. The problem is that
there is no way to wait for a conversion handler is blocked
in a sleeping *_user access before module unloading. The module
count is also not increase in this case.

I previously thought it could be avoided by always putting
the compat wrapper into the same module and using the reference
counting that is done by VFS on ->module of the char device or
file system converted. But that doesn't work because 
the ioctl32 lookup is independent from the file descriptor
and a conversion handler can be entered even after ->release
when the right number is passed.

One way to fix it would be to put a pointer to the module
into the compat ioctl hash table and increase the module count atomically
from the compat code. But that would bloat the hash table a lot
and I don't like it very much. Also you would either break the
register_ioctl32_conversion prototype or make it a macro
and assume all calls are from the same module, which is also 
quite ugly.

A better solution would be to switch the few users of 
register_ioctl32_conversion() over to a new ->ioctl32 method
in file_operations and do the conversion from there. This would
avoid the race because the VFS will take care of the module
count in open/release.

Michael did a patch for this some time ago for a different motivation -
he had some benchmarks where the hash table lookup hurt and it was
noticeable faster to use a O(1) ->ioctl32 lookup from the file_operations
for his application.

An useful side effect would be also to the ability to support 
a per device ioctl name space. While the core kernel doesn't have
much (any?) ioctls with duplicated numbers this mistake seems
to be quite common in out of tree drivers and it is hard to 
fix without breaking compatibility.

And it would be faster for this case of course too, so even performance
critical in kernel ioctls could be slowly converted to ioctl32
I wouldn't do it for all, because the current central tables work
reasonably well for them and most ioctls are not speed critical
anyways.

As for in kernel code it won't affect much code because near 
all conversion handlers in the main tree are not modular (alsa 
is one exception, there are a few others e.g. in some raid drivers). 
I expect it will be a bigger problem in the future though as ioctl 
emulation becomes more widespread and is done more in individual drivers.

averell:lsrc/v2.6/linux% gid register_ioctl32_conversion | wc -l
75
averell:lsrc/v2.6/linux% 

In tree users are alsa, aaraid, fusion, some s390 stuff, sisfb, alsa

My proposal would be to dust off Michael's patch and convert 
all users in tree over to ioctl32 and then deprecate and later remove
(un)register_ioctl32_conversion 

Comments?

It certainly helps performance, at least for me.

There were two additional motivations for my patch:
1. Make it possible to avoid the BKL completely by writing
   an ioctl with proper internal locking.
2. As noted by  Juergen Kreileder, the compat hash does not work
   for ioctls that encode additional information in the command, like this:

#define EVIOCGBIT(ev,len)  _IOC(_IOC_READ, 'E', 0x20 + ev, len)

I post the patch (updated for 2.6.10-rc2, boots) that I built for
Juergen, below. If there's interest, let me know.

I'd like to add that my patch does not touch any in-kernel users,
that would have to be done separately, probably as a first step
simply taking the BKL inside ioctl_compat.

Good point.  It is the first step towards BKL less native ioctls. So it's 
certainly a good idea even for the non compat case.

Patch looks good to me, except for some messed up white space
that is probably easily fixed.

I doubt any of the compat wrappers need BKL, they never touch
any global state and then just call sys_ioctl which takes the BKL
only when needed.

Ok there is a slight possibility that out of tree code wrote
compat wrappers that need BKL, but in that case they will just
have to deal with the bugs. Removing register_ioctl32_conversion
and some comments would take care of them anyways.

I mean out of tree code can just implement ioctl_compat by taking the BKL
if it needs it.

Most of it actually. But perhaps your mailer just messed up the patch?

Anyways, if there are no negative comments I would recommend you
submit your patch (preferably in a non messed up form) to akpm@osdl.org
for inclusion into -mm*. The other parts of the proposal (converting
the existing users and deprecating register_ioctl32_conversion) could be 
attacked then.

There is also some related work that could be done easily then,
e.g. the network stack ioctls currently drop the BKL as first thing.
With ioctl_native that could be probably done better. There may 
be other such low hanging fruit areas too.

OK, so here's a cleaned-up version, against 2.6.10-rc3.
Please comment (and please Cc me, I'm not on the list).
If there are no negative comments I will try to submit to akpm@osdl.org

Andi, I'm trying again with an in-line patch,
if the white-space is mangled by the mail system again,
please let me know so I know to resend as an attachment.

Thanks,

I don't really understand how this should deal with drivers that have
both generic and private ioctl conversion handlers. E.g. 
drivers/s390/block/dasd*.c want to go through the handlers in 
fs/compat_ioctl.c for stuff like BLKGETSIZE, while it also allows
third party modules to dynamically register additional ioctls.
See drivers/s390/block/dasd_cmb.c for an example, I think EMC are
doing something similar to support their drives.

If the dasd driver now implements an ioctl_compat() method, who will
call the standard conversion handlers?

How about just calling back to a special function from these

Sorry, I don't understand. AFAICS, if the driver does not have a
ioctl_compat() file op, it will only be called for those ioctl numbers
that are registered in fs/compat_ioctl.c, but not for the ones that were
added by a third party module.
If it has a ioctl_compat() function, it can handle its own ioctls including
those that are dynamically added, but not any generic ones that have static
conversion functions in fs/compat_ioctl.c. Do you mean it should call back
from its private ioctl_compat() function to the global ioctl32_hash_table[]
lookup?

Yes.

Some ioctl paths already work this way, e.g. in the block layer.

Hmm. I just had another idea. Maybe it's easier to return -ENOIOCTLCMD

about the change below?

I like the idea very well.  Other benifits in addition:

3. Can avoid conflict of ioctls with the same value since the
   convertor is registered locally.

4. Can reject unsupported ioctls for the device (but may be valid for
   other devices) before converting the data - the same reason as
   above.

It conflicts :) When I wrote the original patch for 2.6.8.1
I didnt see the unlocked_ioctl.patch.

unlocked_ioctl is the same as ioctl_native in my patch, except that

1. I added more documentation in several places :)
   (notably Documentation/filesystems/Locking)

2. I thought it a bit silly to name a function for what
   it does not do (does not take a lock), and we
   still need a call for the compat layer.

My patch adds another call to enable special handling
for 32 bit ioctls on 64 bit systems.

I could look at porting to -rc3-mm1, unless
we dont want to back unlocked_ioctl.patch off.
What do people here think?

Just rid of the dynamic hash changes. I don't have any plans 
to convert all the static ioctls in fs/compat_ioctl.c (that would
be a lot of work without clear gain)

This is another "official" way which is more powerful. I suppose it will

the ALSA changes are mine but i'm otherwise building ontop of the 
following patch in -rc3-mm1:

 http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.10-rc3/2.6.10-rc3-mm1/broken-out/unlocked_ioctl.patch

whichever approach gets adopted upstream, the various actors ought to
synchronize a bit more - this is the third approach so far in a very
short interval to get rid of the BKL in ioctls :-)

I think Michael's patch is best (but I'm probably biased) because it addresses
the independent problem of a race in unregister_ioctl32_conversion() too
(and some other smaller issues in ioctl 32bit emulation)

Andrew, could we replace unlocked_ioctl.patch with Michael's patch? Adapting
depending code should be very easy, since only the name of the function
vector has changed.

Here it is for review (against 2.6.10-rc3) http://lkml.org/lkml/2004/12/15/62
I plan to incorporate Arnd Bergmann's comments and repost later today.

The two new methods (ioctl_native and ioctl_compat) are in the same patch
because they basically touch the same piece of code and would be hard
to separate. The other stuff (actually replacing register_ioctl32_conversion and 
converting a few obvious users to use the BKL less fast path) will be addon patches.

Please remove the struct inode * argument, it's easily retrievable
from file->f_dentry->d_inode.  The ioctl prototype is a leftover from
really old days where that wasn't true.

[PATCH] unregister_ioctl32_conversion and modules. ioctl32 revisited.

[Michael S. Tsirkin]

Hello, Andrew!
Since I didnt get any negative comments on this (and some positive)
Andi Kleen suggested I submit the following patch to you.
It boots fine for me, please consider for mainline inclusion.

Dependencies:
The patch below is against 2.6.10-rc3. Please note it replaces
Ingo's ->unlocked_ioctl patch from rc3-mm1, so you have to back that off
before applying mine to mm:

http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.10-rc3/2.6.10-rc3-mm1/broken-out/unlocked_ioctl.patch

Please mail me directly with comments since I'm not on the list.

Changes from the last version I posted ( http://lkml.org/lkml/2004/12/15/62 )
- Two whitespace cleanups. I hope its all good now.
- Arnd Bergmann's idea: make it possible to go back from ioctl_compat
  to hash lookup (good for static ioctl tables) by returning -ENOIOCTLCMD
  from ioctl_compat
- Petr Vandrovec's idea: add HAVE_... macros to make it easier for
  out-of-kernel modules to detect the new file_operations.

Description:
The patch introduces two new methods (ioctl_native and ioctl_compat):
ioctl_native is called on native ioctl syscall, without BKL being taken,
and is, in that respect, equivalent to Ingo's unlocked_ioctl (which is
why it conflicts).
ioctl_compat is called on compat (i.e. 32 bit app on 64 bit OS) ioctl,
again without BKL being taken.
If a new call is not defined, default to the old behaviour.
(It should be possible for me to build a patch that applies on top of Ingo's
unlocked_ioctl, if its really needed let me know and I'll look at it the next
week.)

There was an additional motivation for my patch:
As noted by  Juergen Kreileder, the compat hash does not work
for ioctls that encode additional information in the command, like this:

#define EVIOCGBIT(ev,len)  _IOC(_IOC_READ, 'E', 0x20 + ev, len)

can we be sure this will never escape to userspace?  i can think of
somewhere else we already do this (EFSCORRUPTED) and it does (somewhat
deliberately escape to userspace) and this causes confusion from time
to time when applications see 'errno == 990'

It's safe for the compat ioctl case. If someone wants to use the
same function for the compat and native handler, it would be a bug
to return -ENOIOCTLCMD from that handler with the current code.

To work around this, we could either convert -ENOIOCTLCMD to -EINVAL
when returning from sys_ioctl(). Or we could WARN_ON(err == -ENOIOCTLCMD)
for the native path in order to make the intention clear.

That would be -ENOTTY, I think.

David, this still has the bogus address_space operation in addition to
the vm_operation.  page_mkwrite only fits into the vm_operations scheme,
so please remove the address_space op.  Also the code will be smaller
and faster witout that indirection..

For the native case the new naming is stupid.  The old ioctl_unlocked
made perfect sense while ioctl_native doesn't - after all ->ioctl is
native aswell.  Also this still has the useless inode * paramater in
the method signature.

What about moving fs/Kconfig.reiser4 to fs/reiser4/Kconfig?  This is
the logical place for it and makes dropping in a new version of the fs
easier.

Here's a better and much simpler patch:

 - add ->unlocked_ioctl method and a do_ioctl wrapper in ioctl.c so all
   places calling ->ioctl get it.
 - add ->compat_ioctl method and call it in compat_sys_ioctl before doing
   the hash lookup for registered handlers.
 - streamline compat_sys_ioctl and move the complex error reporting into
   a function of it's own

Regarding the inode* parameter, the change to remove it would be trivial,
though I personally dont care and I didnt see anyone else comment on that.

From: Hirokazu Takata <takata@linux-m32r.org>

Hello,

Here is a patchset to fix a bug of m32r kernel 2.6.9 that a code on
a noexec page can be executed incorrectly.

For good security, stack region should be non-executable. 
This fix is also needed to achieve non-executable stack.

Please apply this to 2.6.10 kernel if possible.

Thank you.

And apparently it's broken on NUMA.  I couldn't find

This patch removes an unused variable in the synaptics_data struct and

On a dual-Opteron w/ NUMA I had to apply the Jesse's patch to compile the 
kernel, but it does not boot.  It only prints this to the serial console:

wrt. necessity, it's quite handy: check out the 2.6.10 changelog, almost
all preemption bugs wrt. smp_processor_id() were found this way.

what precisely is the 'mess' you are referring to?

is it the way the include file falls back to the original
smp_processor_id() definition if an arch doesnt define
__smp_processor_id()? I could get rid of that and just require every
arch to define __smp_processor_id().

or is it the addition of _smp_processor_id() as a way to signal 'this
smp_processor_id() call in a preemptible region is fine, trust me'? We
could do smp_processor_id_preempt() or some other name - any better
suggestions?

I'd just kill the debug check and rely on the eye of the review to not
let new users of smp_processor_id slip in.

relying on that is quite futile. E.g. in the block IO code it needed 3-4
iterations even after the first instance was found to get all the cases
right. There are functions that are always called from under a lock then
some unlocked call happens and we've got trouble. Often the bug is some
very rare and obscure corruption of a statistics value, nobody really
notices that.

by today i think we've identified most of the places that can safely do
smp_processor_id() in a preemptible section (in x86 and x64) - it's only
around 3% of the total smp_processor_id() use. I'd rather allow these
exceptions and flag new exceptions as they get added - they are added at
least an order of magnitude more rarely than smp_processor_id() gets
added.

I also tried it on an AMD64 system (3500+ on A8V Deluxe) and did not 
observe any anomalies, but I am using Gnome, not KDE.

I saw a message that latency tests were wanted, but I don't normally have 
a workload in which this can be observed.  Perhaps someone could provide a 
suggestion?  I did try some dvd-burning sessions.  Subjectively speaking, 
there didn't seem to be any improvement over 2.6.10, and it may have been 
a bit worse.

Now I'm not seeing anything wrong either, so it must have been accidental.  I

[PATCH] deprecate (un)register_ioctl32_conversion

[Michael S. Tsirkin]

Hello, Andrew, all!

Since in -mm1 we now have a race-free replacement (that being ioctl_compat),
here is a patch to deprecate (un)register_ioctl32_conversion.

Sorry, but this is a lot too early.  Once there's a handfull users left
in _mainline_ you can start deprecating it (or better remove it completely).

So far we have a non-final version of the replacement in -mm and no single
user converted.

I dont know. So how will people know they are supposed to convert then?

Christoph, I know you want to remove the inode parameter :)

Otherwise I think -mm1 has the final version of the replacement.

Tell the janitors about it - or do it yourself.  Except for taking care
of the BKL going away it's a trivial conversion.

There were never more than a handful users of it anyways. So I think
Michael's suggestion to deprecate it early is very reasonable.

For me it looks quite final.

It's 72 callers in mainline.  Aka 72 new warnings for an allmodconfig
build.  This isn't reasonable just because the interface got out of
fashion.

- Spacing is broken.
- I think the convention would be to use EINVAL here. ENOTTY mean 'this
  device does not support ioctl', while EINVAL is used for 'ioctl is
  supported, but not this number'.
- I would put the conversion only in the place that calls ->native_ioctl
  in order to make clearer why it is done.

I don't think it's needed for the compat case, as we are already
handling ENOIOCTLCMD here by doing to hash lookup.

I'd also prefer the code to be based on Christophs version, which 
unfortunately is lacking handling for ENOIOCTLCMD from compat_ioctl,
but otherwise looks better.

Good to see that ioctl_native and ioctl_compat ops are already there!

Will it be merged to 2.6.11?  If so, I'll prepare the patch to convert
the ALSA compat32 stuff, too...

It should be enough to just change the ->pml4 to ->pgd. Assuming that it
worked with the original 4level patches.

Surprisingly, this is what I get for 'make distclean':

[PATCH 2.6.10-mm2] m32r: build fix

[Hirokazu Takata]

Hi,

This patch is required to fix compile errors of 2.6.10-bk8 and 2.6.10-mm2
for m32r.  Please apply.

This was originally given by the following patch:
  [PATCH] move irq_enter and irq_exit to common code
  http://www.ussg.iu.edu/hypermail/linux/kernel/0411.1/1738.html

I think it was maybe accidentally dropped only for the m32r arch
due to a patching conflict with the other patches or something like that...

Thanks,

Re: 2.6.10-mm2

[Christoph Hellwig]

> +rio-cli-conversion.patch
> +rio_linux-64-bit-workaround.patch

RIO is totally broken on all plattforms, and rio-cli-conversion.patch
makes it even more broken with things like:

-#define disable(oldspl) save_flags (oldspl) 
-#define restore(oldspl) restore_flags (oldspl) 
+#define disable(oldspl) local_irq_save(oldspl);
+#define restore(oldspl) local_irq_restore(oldspl) ;

or

+       if (PortP->gs.flags & ASYNC_CLOSING){ 
+               interruptible_sleep_on(&PortP->gs.close_wait);
+       }

please drop rio-cli-conversion.patch and mark the driver BROKEN to wait
a little before finally removing it unless it'll get a major rewrite.

The acpi_power_off issue (acpi_power_off is called but the laptop doesn't shut
down) is back (in -mm1 already). I suspect it has never disappear completely:
maybe it only happens in some cenarios (like "only when AC is plugged in" or
something like that). The report is done, I'll try to get more info soon (when
does this happen and when it doesn't) and will report it by then.

Improves the search function in menuconfig - better display of what
a symbol depends on / selects.
Also display the same information when getting help on a symbol.

Try it out next time you start up menuconfig.

Kudos to Roman Zippel for implementing the core functionality.

That's not right either. Filesystems really shouldn't be overloading the
vm_ops on memory mappings (as has been made clear to me) and the VM low-level
paging routines shouldn't be touching a_ops (as has also been made clear to
me). I also have other reasons I don't want to have ordinary files with
specialised vm_ops.

I suppose I could try and build a little knowledge about fscache into the
VM... that might be reasonable.

Remember also that your change is going to affect NFS too eventually, assuming
NFS caching support ends up being done this way. It may also affect other
filesystems, such as SMB/CIFS and Coda eventually should they partake of
fscache services too.

To make life bearable for out-of kernel modules, the following patch
adds 2 macros so that existance of unlocked_ioctl and ioctl_compat
can be easily detected.

Stare at this as I might, I dont understand why does it make sence.
So if filp->f_op is NULL, you are then checking filp->f_op->ioctl?
Looks like an oops to me.

What should be there:

[PATCH] fget_light/fput_light for ioctls

[Michael S. Tsirkin]

Hello!
With new unlocked_ioctl and ioctl_compat, ioctls can now
be as fast as read/write.
So lets use fget_light/fput_light there, to get some speedup
in common case on SMP.

That's not the way we're making additions.  Get your code merged and
there won't be any need to detect the feature.

I doesn't make sense, but fortunately files with NULL filp->f_op don't
happen in practice (need to research whether it can't happen in theory
either so we could lose lots of checks)

I would agree that it shouldn't be used for in tree code, but for
out of tree code it is rather useful. There are other such feature macros
for major driver interface changes too (e.g. in the network stack).

Which is the only place doing it.  We had this discussion in the past
(lastone I revolve Greg vetoed it).  We simply shouldn't clutter our
headers for the sake of out of tree drivers - with LINUX_VERSION_CODE
we've already implemented a mechanism for out of tree drivers.

p.s. droppe alsa-devel from Cc because of the braindead moderation policy.

Interesting. At least for character devices coming out of modules I think you
dont - you need at least fops->owner.

So now if I dont have ->ioctl the ioctl_compat wont be called.
What if I only have unlocked_ioctl?

Indeed.  In my test setup I didn't have a driver using both.  So let's
think a little more what checks we want.

The original intention (pre-patch) was that without an ioctl entry
we'd skip the hash table lookup and skip right to trying the few standard
ioctls.

So with ->compat_ioctl we should try that one first, then checking
for either ->ioctl or ->unlocked_ioctl beeing there.  Like the patch
below (this time it's actually untested because all my 64bit machines
are in use):

I don't know who had this discussion and did this "decision", but 
for record I disagree.

That's incredibly ugly. I always hate these checks in source code
because it's never clear what exactly they are testing for. 
And requires unreasonable work to find out when exactly the feature was 
added. And it doesn't really work when there are backports in older trees.
In short there are many drawbacks. HAVE_* is much nicer.

OK, right, that's a problem.  There's no reason for that policy.  Perex,

Amen to that. Since it conflicts with this change, here again is my patch
to make it possible for the compat_ioctl to drop back on the standard
conversions.
Applied on top of Christoph's last patch (above).

[PATCH] fget_light/fput_light for ioctls (fixed)

[Michael S. Tsirkin]

Hello!
Sorry, that patch had a typo. Here's an updated version.

>>> Quoting r. Michael S. Tsirkin (mst@mellanox.co.il)

With new unlocked_ioctl and ioctl_compat, ioctls can now
be as fast as read/write.  So lets use fget_light/fput_light there,
to get some speedup in common case on SMP.

When Greg made sysfs GPL only, I've asked whether it is possible to merge
vmmon/vmnet in (and changing its license, of course).  Answer on LKML was 
quite clear: no, you are not interested in having vmmon/vmnet in Linux 
kernel as you do not believe that they are usable for anything else than VMware.  

So please tell me what I can do to satisfy you?  You do not want our modules
in kernel tree, and you do not want to allow us to detect kernel interface
easily.  Of course we can use autoconf-like scripts we are using for
example to detect pml4/pgd vs. pgd/pud vs. pgd/pmd/pte vs. pmd/pte only,
but each time you can detect feature by looking at flags and not by trying
to build one source after another detection is simpler and more reliable.

BTW, vmmon will still require register_ioctl32_conversion as we are using
(abusing) it to be able to issue 64bit ioctls from 32bit application.  I
assume that there is no supported way how to issue 64bit ioctls from 32bit
aplication anymore after you disallow system-wide translations to be registered
by modules.

While I think there could be users, these users would probably come only
after the code was GPLed, so this is kinda chicken & egg.

I don't care at all for non-opensource users, or small opensource glue for
a big propritary user.

Why are you issuing 64bit ioctls from 32bit applications?

LINUX_VERSION_CODE never worked in last ~4 years as definite key to make
decision about supported API.  Vendors are porting stuff across releases,
there exists additional trees like -mm, -wolk, -ac, and even if you look 
at the current example with deprecating register_ioctl32_conversion you'll 
find that it does not work: 

2.6.10 kernel which presents itself as 0x02060A does have this, but 
does not have {compat,native}_ioctl.  

2.6.10-mm2 kernel, which presents itself as 0x02060A too, has 
{compat,native}_ioctl, and also has register_ioctl32_conversion.  

And there is intention to apply patch to 2.6.10-mmX which will present 
itself as 0x02060A again, will have {compat,native}_ioctl, and will either
not have register_ioctl32_conversion at all, or will produce 
unfortunate unwanted annoying warning when this function is used.

So you'll have two 2.6.10 kernels, one says that register_ioctl32_conversion is
only way to do things, and at same time it will say that register_ioctl32_conversion
is deprecated.  Strange, isn't it?  Unfortunate?  Maybe.  Can this work with
LINUX_VERSION_CODE?  Definitely not without an additional checks on other
things.

Same situation exists with pml4/pgd/pud I described in previous mail.  You have
2.6.10 with pgd only, 2.6.10-bkWhatever with pgd/pud, and 2.6.10-mmX with pml4/pgd.
This cannot be checked by LINUX_VERSION_CODE too...

Other changes usually add some #define which can be checked (like PUD_MASK or
pml4_offset), but sometime it happens that no useful macro is created and
test-compile is only way how to discover things (from past let's name epoll
change backported from 2.5.x to 2.4.x-wolk, SKAS's change to do_mmap_pgoff 
prototype living in SUSE tree for a bit, or nopage's change in prototype 
around 2.6.1).

There are three reasons (main reason is that vmware is 32bit app, but it is how
things are currently laid out; even if there will be 64bit app, 32bit versions are
already in use and people wants to use them on 64bit kernels):

* USB.  usbfs API is written in a way which does not allow you to safely wrap
it in "generic" 32->64 layer, and attempts to do it in non-generic way in usbfs
code itself did not look feasible year ago.  Even on current 64bit kernels it is not
possible to issue raw USB operations from 32bit apps, and I do not believe that
it is going to change - after all, just issuing ioctl through 64bit path from application
which is aware of 64bit kernel is quite simple, much simpler than any attempt to
make kernel dual-interface.

* parport interface, serial port:  not all APIs were implemented in kernel.  Current
kernels do wrap all APIs vmware needs, but older kernels do not, and so we had to find
some solution for older kernels too.  Not so surprisingly, solution we had in place for
USB works for them too...

* floppy:  it is actually different from examples above, as FDRAWCMD command is
supported by 32->64 layer, but it is supported incorrectly.  Due to this all above
started, as we had to make application aware of kernel it runs on, as FDRAWCMD on 32bit
kernel returns 80 byte structure, while 104 byte on 64bit kernel, and you do not now
which one you'll get until you call this ioctl...  And once we had code in place,
it was reused for USB and later for ppdev & serial.

So we added simple wrapper to vmmon which just gets {64bit-ioctl-number, 64bit-arg-argument}
and passes it down to 64bit sys_ioctl:

/* Use weak: not all kernels export sys_ioctl for use by modules */
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 5, 66)
asmlinkage __attribute__((weak)) long
sys_ioctl(unsigned int fd, unsigned int cmd, unsigned long arg);
#else
asmlinkage __attribute__((weak)) int
sys_ioctl(unsigned int fd, unsigned int cmd, unsigned long arg);
#endif

...

static int
LinuxDriver_Ioctl3264Passthrough(unsigned int fd, unsigned int iocmd,
                                 unsigned long ioarg, struct file * filp)
{
   VMIoctl64 cmd;

   if (copy_from_user(&cmd, (VMIoctl64*)ioarg, sizeof(cmd))) {
      return -EFAULT;
   }
   if (sys_ioctl) {
      int err;

#if LINUX_VERSION_CODE < KERNEL_VERSION(2, 4, 26) || \
   (LINUX_VERSION_CODE >= KERNEL_VERSION(2, 5, 0) && LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 3))
      err = sys_ioctl(fd, cmd.iocmd, cmd.ioarg);
#else
      unlock_kernel();
      err = sys_ioctl(fd, cmd.iocmd, cmd.ioarg);
      lock_kernel();
#endif
      return err;
   }
   return -ENOTTY;
}


We were thinking about creating 64bit thread, and issuing 64bit syscalls from it, but 
it looked more fragile than code above.

There's an swsusp regression on my box (AMD64) wrt -mm1.  Namely, 2.6.10-mm2 
does not suspend, but hangs solid right after the critical section, 100% of 
the time.

Agree that's a problem. We just need an alternative interface here
or I try to come up with an x86-64 specific hack (I think it's possible
to do the compatibility x86-64 specific, just not in compat code for
all architectures who have truly separated user/kernel address spaces) 

I hope the USB people will eventually add a better interface here.

But that's a non issue for the new kernels affected by the new ioctl 
interface.

Did you submit a patch for that?  If not you should.

The magic 64bit interface isn't a very good interface, don't expect
that to be supported in the future.

[patch] 2.6.10-mm2: move CPUSETS above EMBEDDED

[Adrian Bunk]

The placement of CPUSETS somewhere in the middle of the EMBEDDED options 
breaks the EMBEDDED submenu (at least in menuconfig).

The patch below fixes this by simply moving CPUSETS above EMBEDDED.

There's no reason for offering a MIPS-only driver on other architectures 
(even though it does compile).

Even better dependencies on specific MIPS variables might be possible 
that obsolete this patch, but this patch fixes at least the !MIPS case.

You use via-agp. That's fine, since I get the same oops on nvidia-agp. So the common
piece seems to be radeon drm.

The oops can be avoided by reverting

agpgart-allow-multiple-backends-to-be-initialized.patch
drm-add-support-for-new-multiple-agp-bridge-agpgart-api.patch

I hoped that floppies will die before...  FDRAWCMD receives array
of floppy_raw_cmd structures, and to find how many of these structures
you have to peek into every of them to find whether there is next one or
not, and structures itself contain pointers to other memory...  I'll code up
something during weekend.

With per-file compat_ioctl ipx ioctls (using SIOCPRIVATE+X range) could
be made to work too, so only thing left for me is USB.

Yes, we've been talking about a usbfs2 for a long time now, but no one
has stepped up and done the work.  It would look a lot like gadgetfs,
which only has a limited number of ioctls needed for its operation.

But I don't see where the problem is unique to usbfs here, don't we
properly use the 32->64bit ioctl conversion code to solve this kind of
issue?  Are we using it incorrectly?

DaveM can probably give you more details since he tried unsucessfully
to make it work. I think the problem is that there is no enough
information for the compat layer to convert everything.

Here's his comment from fs/compat_ioctl.c.

On x86-64 it can be a bit easier because you can get away with
only partially converting a data structure because the 32bit
space is still visible from the kernel. But that doesn't work
on some other archs.

 * because of the fancy asynchronous way URB status/error is written
 * back to userspace, we'll need to fiddle with USB devio internals
 * and/or reimplement entirely the frontend of it ourselves. -DaveM
 *
 * The issue is:
 *
 *      When an URB is submitted via usbdevicefs it is put onto an

When the usbfs async stuff writes back the status, we are no
longer within the original syscall/ioctl execution any more,
therefore we don't know if we're doing this for a compat task
or not.

Technically we could create a "is_compat_task()" type thing
to check but Andi has always been against that and he's given
good reasons.  I tend to agree with him, especially in that there
are valid cases where a compat task might want to make 64-bit
system calls (f.e. to support 64-bit process debugging from
a 32-bit binary, and this is not fantasy as sparc64 could support
this right now)

As mentioned in the code comment, there are also memory management
issues.  We can cons up a temporary kernel buffer in order to
convert the 32-bit structs into 64-bit ones the usbfs code
expects, but then we have the issue of whether we can keep that
buffer around during the entirety of the async operation and
if so who in the world will free it up and how will they know
to do so?

Finally there are complications wrt. using a kernel buffer in that
we have to thus use set_fs(KERNEL_DS) in order for kernel buffers
to be passed into the usbfs routine translated.  This means that
user space accesses of the actual user buffers wouldn't work, and
we thus need to use temporary kernel buffers for that as well.
This is also incompatible with the async nature of how usbfs wants
to work.

I would suggest something that had a fixed sized and fixed layout
status block.  Something that doesn't change layout or size on any
platform.

It's the pointers all over the place in the usbfs ioctl commands
that causes all of the problems.  If you split things up into,
say, user buffer pointer/len struct and status block struct, it might
be a lot easier to support this stuff.  But I'm even skeptical about
this working.

Thanks Dave for the update. I misremembered and I don't think
I can fix this up for x86-64.  We'll need a new interface of some sort.

Poor man way of doing this is just ripping ioctl-related code from usb's devio.c
to separate file, and build this file twice, once for native_ioctl and 64bit
urb structure, and once for compat_ioctl and 32bit urb structure.

I see no reason why it should not work for apps which submit & reap URBs through
32bit or 64bit API exclusively, without mixing them (and when you mix them,
you'll get reasonable error that you did not submit specified URB).

Only problem is that after that USB code "knows" about 32bit API.  But it is
intention of compat_ioctl, no?

P.S.:  When designing new API, please do not make it unnecessary complicated.
USB video needs rather large bandwidth and low latency, so please no ASCII

In measurements published on linux-usb-devel, pure userspace calls using
the current usbfs code generated almost full bandwidth usage (within the
hardware limits).  So adding the scatter-gather api interface to usbfs
wouldn't really provide that much benefit.

And, we can always use help in designing such an API, if you could find
someone at your company to help us out in doing so... :)

Actually, the measurements I recall were using that
nasty usbfs-specific async API ... or using huge
buffers with the synchronous/blocking calls, so
the hiccups added by scheduling latencies didn't
kick in very often.


> And, we can always use help in designing such an API, if you could find

Or just doing something like gadgetfs, where the standard
Linux "libaio" calls work just fine.  I was certainly able
to stream 24 Mbyte/sec isochronous transfers (that's the
top speed possible with one high speed ISO endpoint).

The key point is that one userspace IOCB should map directly
to one URB in the kernel; and one userspace file (descriptor)
should map to one USB endpoint.  For a host side API, it turns
out that isochronous URBs already have limited scatter/gather
style support -- each one maps to several packets.

I think it'd be best to use the existing AIO support rather
than have usbfs2 create yet another USB-specific thing.

Ok, problem is that device_power_{down,up} is right thing, and
neccessary for many machines to work...

...so... could you go through sysdev_register()s, one by one,
commenting them to see which one causes the regression? That driver
then needs to be fixed.

As a quick fix, wouldn't it be easy enough to just mark USBDEVFS_IOCTL as
COMPATIBLE_IOCTL()? The number is actually different for 32 and 64 bit kernels,
so a 32 bit application that knows about this could use 64 bit data structures
and then just call ioctl(fd, USBDEVFS_IOCTL64, data) instead of using a weird
hack to achieve exactly the same.
Applications trying to call the 32 bit USBDEVFS_IOCTL would still see -EINVAL
because there is no wrapper for this.
Maybe the same can be done for some of the other ioctl calls. It effectively
means moving part of the compat layer to user space from fs/compat_ioctl.c,
but it appears that applications are already doing this.

This patch adds an API to reserve some number of pages for exclusive use
of calling thread.  This is necessary to support operations that cannot
tolerate memory allocation failures in the middle (reiser4 uses this API
to not have to undo complex uncompleted (due to ENOMEM) filesystem tree
modifications).

Implementation is simple: reserved pages are stored in a list hanging
off calling task_struct. Caller is to manually release unused pages.

This API is supposed to be used for small reservation (no more than few
dozens of pages).
 
Looking forward for advices on how to do that better/properly
Thanks

This patch adds an API to reserve some number of pages for exclusive use of
calling thread.  This is necessary to support operations that cannot tolerate
memory allocation failures in the middle.  Implementation is very simplistic
and would only work efficiently for small reservations (no more than few
dozens of pages).

Reserved pages are stored in a list hanging off calling task_struct.  This
list is only accessed by the current thread, hence, no locking is required. 
Note that this makes use of reservation from interrupt handlers impossible
without some external synchronization.  Caller is responsible for manually
releasing unused pages by calling perthread_pages_release(int nrpages) with
proper argument.

This will end up reserving more pages than were asked for, if
current->private_pages_count is non-zero.  Deliberate?

this is a completely useless wrapper that doesn't buy anything.

Can probably be written much simpler as:

int perthread_pages_reserve(int nrpages, int gfp)
{
	LIST_HEAD(accumulator);
	int i;

	list_splice_init(&current->private_pages, &accumulator);

Now the big question is, what's synchronizing access to
current->private_pages?

Would be much more readable with the error condition handling at the
end of the function and a goto.

Would be written much cleaner with a single return statement and the
comment above the function, ala:

/*
 * try to allocate pages from the per-thread private_pages pool. No
 * locking is needed: this list can only be modified by the thread
 * itself, and not by interrupts or other threads.
 */
static inline struct page *perthread_pages_alloc(void)
{
	struct list_head *perthread_pages = &current->private_pages;
	struct page *page = NULL;

	if (!in_interrupt() && !list_empty(perthread_pages)) {
		page = list_entry(perthread_pages->next, struct page, lru);
		list_del(&page->lru);
		current->private_pages_count--;
	}

	return page;
}

You should at least move the !in_interrupt() condition out here.

Umm, it's obviously correct as we're thread-local.  Objection taken back :)

I hope this has not been extensively discussed yet, and I missed the 
thread but, does everybody think this is a good thing?

This seems like a very asymmetrical behavior. If the code explicitly 
reserves pages, it should explicitly use them, or it will become 
impossible to track down who is using what (not to mention that this 
will slow down every regular user of __alloc_pages, even if it is just 
for a quick test).

Why are there specialized functions to reserve the pages, but then they 
are used through the standard __alloc_pages interface?

At the very least this test should be moved to the very beginning of the 
function. It is of no use to calculate "can_try_harder" before running 
this code if it will use a reserved page.

Having a specialized function to get the reserved pages, would also make 
the logic in "perthread_pages_reserve" more clear (i.e., that comment 
would become unnecessary), and lose the test to "in_interrupt()" in 
"perthread_pages_alloc", if I'm reading this correctly.

Safe without locks so long as there is no other way to get at another
process's private_pages. ;)

That seems to be the whole point of the patch, as that way it'll serve
all sub-allocators or kernel function called by the user.  Without this
behaviour the caller could have simply used a mempool.

I still don't get it why reiserfs can't put the preallocated 
pool somewhere private like all other users who do similar things
do too (and yes there are quite a lot of subsystems who do 
preallocation) 

Why pollute task_struct for this?

Yes. This is to make modular usage possible, so that


        perthread_pages_reserve(nrpages, gfp_mask);

        /* call some other code... */

        perthread_pages_release(unused_pages);

works correctly if "some other code" does per-thread reservations
too.

I disagree. Patch introduces explicit API

int  perthread_pages_reserve(int nrpages, int gfp);
void perthread_pages_release(int nrpages);
int  perthread_pages_count(void);

sufficient to create and use per-thread reservations. Using
current->private_pages_count directly

 - makes API less uniform, not contained within single namespace
   (perthread_pages_*), and worse,

 - exhibits internal implementation detail to the user.

Completely disagreed, hiding all the details doesn't help for such
trivial access, it's just obsfucating things.

But looking at it the API doesn't make sense at all.  Number of pages
in the thread-pool is an internal implementation detail and no caller
must look at it - think about two callers, e.g. filesystem and iscsi
initiator using it in the same thread.

That's the whole idea behind this patch: at the beginning of "atomic"
operation, some number of pages is reserved. As these pages are
available through page allocator, _all_ allocations done by atomic
operation will use reserved pages transparently. For example:

        perthread_pages_reserve(nr, GFP_KERNEL);

        foo()->

            bar()->

                page = find_or_create_page(some_mapping, ...);

        perthread_pages_release(unused_pages);

find_or_create() pages will use pages reserved for this thread and,
hence, is guaranteed to succeed (given correct reservation).

Alternative is to pass some sort of handle all the way down to actual
calls to allocator, and to modify all generic code to use reservations.

Nikita.

I don't see how this can work.

        /* make conservative estimation... */
        perthread_pages_reserve(100, GFP_KERNEL);

        /* actually, use only 10 pages during atomic operation */

        /* want to release remaining 90 pages... */
        perthread_pages_release(???);

Can you elaborate how to calculate number of pages that has to be
released?

Nikita.

That's a good question actually, and it's true for the original
version aswell if we want (and to make the API useful we must) make
it useable for multiple callers in the same thread.

Assuming the callers strictly nest we can indeed just go back to the
orininal count, maybe with an API like:

int perthread_pages_reserve(unsigned int nrpages, unsigned int gfp_mask);
void perthread_pages_release(unsigned int nrpages_goal);


	unsigned int old_nr_pages;

	...

	old_nr_pages = perthread_pages_reserve(100, GFP_KERNEL);

	...

	perthread_pages_release(old_nr_pages);

Or just preallocate into a private array.

Maybe I'm being thick, but I don't see how you can protect the reservation
of an outer reserver in the above way:

	perthread_pages_reserve(10);
	...				/* current->private_pages_count = 10 */
		perthread_pages_reserve(10)	/* private_pages_count = 20 */
		use 5 pages			/* private_pages_count = 15 */
		perthread_pages_release(5);

But how does the caller come up with the final "5"?

Seems better to me if prethread_pages_reserve() were to return the initial
value of private_pages_count, so the caller can do:

	old = perthread_pages_reserve(10);
		use 5 pages
	perthread_pages_release(old);

or whatever.

That kinda stinks too in a way, because both the outer and the inner
callers need to overallocate pages on behalf of the worst case user in some
deep call stack.

And the whole idea is pretty flaky really - how can one precalculate how
much memory an arbitrary md-on-dm-on-loop-on-md-on-NBD stack will want to
use?  It really would be better if we could drop the whole patch and make
reiser4 behave more sanely when its writepage is called with for_reclaim=1.

There's an MTRR fix in the -overloaded ck patches. Perhaps it is what

Reiser4 doesn't use this for ->writepage(), by the way. This is used by
tree balancing code to assure that balancing cannot get -ENOMEM in the
middle of tree modification, because undo is _so_ very complicated.

Oh.  And that involves performing I/O, yes?

Why does the filesystem risk going oom during the rebalance anyway?  Is it
doing atomic allocations?

Yes, balancing may read tree or bitmap nodes from the disk.

No, just __alloc_pages(GFP_KERNEL, 0, ...) returns NULL. When this
happens, the only thing balancing can do is to panic.

__alloc_pages(GFP_KERNEL, ...) doesn't return NULL.  It'll either succeed
or never return ;) That behaviour may change at any time of course, but it
does make me wonder why we're bothering with this at all.  Maybe it's
because of the possibility of a GFP_IO failure under your feet or
something?

What happens if reiser4 simply doesn't use this code?


If we introduce this mechanism, people will end up using it all over the
place.  Probably we could remove radix_tree_preload(), which is the only
similar code I can I can immediately think of.

Page reservation is not a bad thing per-se, but it does need serious
thought.

How does reiser4 end up deciding how many pages to reserve?  Gross
overkill?

this looks like the agp backend isn't loading, Mike sent me parts of

make sure that the correct backend for your chipset is loaded (throw a

actually tested -mm2 on my own machine there now and I have a Radeon

The regression is caused by the timer driver.  Obviously, turning 
timer_resume() in arch/x86_64/kernel/time.c into a NOOP makes it go away.

It looks like a locking problem to me.  I'll try to find a fix, although 
someone who knows more about these things would probably do it faster. :-)

Can I get you to take a look at the patches I just posted; they might
need some more work for x86_64, but may be helpful.

if you look at the .config, agp and agp_via are not build as modules.

Actually the error I reported first occurs when X starts, it happens a
second time when I launch neverball (and X get killed).

I attached a dmesg from right after X started, another after neverball
was launched.
output of lsmod and .config are attached to.

Hmm... it used to, when I wrote that code.

This is what happens:

 - we start inserting new item into balanced tree,

 - lock nodes on the leaf level and modify them

 - go to the parent level

 - lock nodes on the parent level and modify them. This may require
   allocating new nodes. If allocation fails---we have to panic, because
   tree is in inconsistent state and there is no roll-back; if allocation
   hangs forever---deadlock is on its way, because we are still keeping
   locks on nodes on the leaf level.

At the time I tested it, it panicked after getting NULL from
__alloc_pages(). With current `do_retry' logic in __alloc_pages() it
will deadlock, I guess.

Worst-case behavior of tree algorithms is well-known. Yes it's overkill.

it looks like agp_backend_acquire is returning NULL in this case, 
[drm:drm_ioctl] pid=10587, cmd=0x6430, nr=0x30, dev 0xe200, auth=1
[drm:drm_ioctl] ret = ffffffed
is the agp acquire ioctl and the return is -ENODEV 

Any ideas Mike why that might happen?

And still does, if OOM decides to kill _your_ task: OOM sets PF_MEMDIE,
and then you don't get to go the retry route at all:

	/* This allocation should allow future memory freeing. */
	if ((p->flags & (PF_MEMALLOC | PF_MEMDIE)) && !in_interrupt()) {

Well, I need the help of The Wise. :-)

If I comment out only the modification of jiffies in timer_resume() in 
arch/x86_64/kernel/time.c (ie line 986), everything seems to work, but I get 
"APIC error on CPU0: 00(00)" after device_power_up(), which seems strange to 
me, because I boot with "noapic".  On the other hand, if it's not commented 
out (ie jiffies _is_ modified in timer_resume()), the machine hangs solid 
after executing device_power_up() in swsusp_suspend().

Right now I have no idea of what happens there, and it seems strange because 
in 2.6.10-mm1 the code in time.c is the same.

Removing the framebuffer from the boot command line solved it... (with
the patch that Mike Werner posted ; without it, it oopsed).

Perhaps calling handle_lost_ticks() like timer_interrupt does is right
thing to do?

Well, but in -mm1, the code is not actually called, right?

If the bridge->agp_in_use is non-zero then drm_agp_acquire would return
-ENODEV.
Previously it would return -EBUSY in this case but agp_backend_acquire
now returns
a pointer to a bridge so there is no distinction made between existence
and busy.

Actually, I saw this APIC error too (on i386, with "noapic"), but I
ignored it because, aside from that message, all of my interrupt
problems were gone and I had fully working swsusp for the first time in
recorded history.

I should see what happens if I recompile with APIC support. Hopefully
I'll be able to get to that today.

Everything is attached.

I passed drm_debug=1 to the kernel. All the drm debug messages appear
when I start X. Neverball is very slow (as if DRM was not enabled)
but does not show any new debug.

Whenever scheme comes up I dont think the current check in __alloc_pages() is 
any good:

        if (order == 0) {
                page = perthread_pages_alloc();
                if (page != NULL)
                        return page;
        }

Two things:

- all instances of an allocator from the current thread will eat from the perthread
  reserves, you probably want only a few special allocations to eat from the reserves?
  Thing is its not really a reservation intended for emergency situations,
  rather a "generic per-thread pool" the way things are now.

- its a real fast path, we're adding quite some instructions there which are only
  used by reiserfs now.

I think in a "final" implementation emergency allocations should be explicitly stated 
as such by the callers ?

Per-thread reservations are only useful when they are transparent. If
users have to call special function, or to pass special flag to
__alloc_pages() they might just use mempool as well. Idea is to reserve
some number of pages before starting complex operation so that generic
function (like find_get_page()) called as part of this operation are
guaranteed to succeed.

Yes, this worries me too. Possibly we should move this check below in
__alloc_pages(), so that per-thread reservation is only checked if
fast-path allocation failed.

The agp_in_use field of the bridge structure is never initialized.
That's the reason why atomic_read fails to read 0.

In vanilla, the bridge is allocated as a static global variable, and
thus initialized to 0 at init. In -mm, the bridge is kmalloc'ed, and
thus not initialized.

The attached patch fixes it and solves my problem (when combined with
http://lkml.org/lkml/2005/1/7/377). DRM is back with good performance.

Actually, this doesn't fix Benoit's problem (even if we were initially
having the same errors (radeon_cp_init called without lock held)).

It seems that memsetting the whole bridge structure to 0 (instead of
juste the agp_in_use field) fixes Benoit's problem too.
No idea which field was responsible for this. New patch attached.

This still happens in -mm3.

Well, I've changed timer_resume() in arch/x86_64/kernel/time.c into the 
following function:

static int timer_resume(struct sys_device *dev)
{
	unsigned long flags;
	unsigned long sec;
	unsigned long ctime = get_cmos_time();
	long sleep_length = (ctime - sleep_start) * HZ;

	if (vxtime.hpet_address)
		hpet_reenable();

	sec = ctime + clock_cmos_diff;
	write_seqlock_irqsave(&xtime_lock,flags);
	xtime.tv_sec = sec;
	xtime.tv_nsec = 0;
	write_sequnlock_irqrestore(&xtime_lock,flags);
	printk ("jiffies = %lu, sleep_length = %ld\n", jiffies, sleep_length);
	return 0;
}

and that's what I get from the log:

Jan 12 19:43:42 albercik kernel: jiffies = 4294847120, sleep_length = 
-3189288131000

(for example - the second number is always negative and huge).  Would it mean 
that get_cmos_time() needs fixing?

[PATCH] fix: macros to detect existance of unlocked_ioctl and compat_ioctl

[Michael S. Tsirkin]

Hi!
I just noticed that my original patch says "ioctl_compat" all over the place
while the actual field name in -mm2 is "compat_ioctl". Doh.
Here's a replacement patch.
PS. Please dont flame me, I do not maintain out of kernel modules, myself :)

To make life bearable for out-of kernel modules, the following patch
adds 2 macros so that existance of unlocked_ioctl and compat_ioctl
can be easily detected.

It does something like get_cmos_time() - get_cmos_time()*HZ. It looks

get_cmos_time() looks okay, but timer){suspend,resume} looks
hopelessly broken.

No, we do not do that in the kernel today, and I'm pretty sure we don't
want to start doing it (it would get _huge_ very quickly...)

Please don't apply this.  Remember, out-of-the-tree modules are on their
own.

Actually we do. e.g. take a look at skbuff.h HAVE_*
There are other examples too.

I disagree since the alternative is so ugly.

I don't know who made this "policy", but actively sabotating or denying

Gee, thanks.  It's not like some out-of-tree code doesn't _want_ to go
into the core kernel, but usually the time between some code being
developed and when it is included is lengthy (i.e. "this feature won't
be accepted until lots of people use it").

You can't claim that this has never been done (e.g. KERNEL_HAS_O_DIRECT,
KERNEL_HAS_DIRECT_FILEIO in 2.4 kernels).  For code that needs to handle
multiple kernel versions this makes life far easier and doesn't actually
hurt anything.  It used to be that you could use LINUX_VERSION_CODE for
this kind of check, but that breaks down quickly with vendor kernels and
the long development cycle.

Well, why don't we convert them to noops, then, at least temporarily?

But the main problem with this is, when do we start deleting the HAVE_
symbols?  After a relativly short period of time, they become useless,
as all kernels of the past year or two have that feature, and why even
test for it?

I agree, that for short term, vendor-patched kernels, it's nice to have
something like that to try to build your out-of-the-tree module.  But
move to get that module into the tree, or provide your favorite vendor
with the properly patched driver (hey, I can dream...)

And is the alternative (using autoconf to build tiny modules testing for
different features) that ugly?  Yeah, I hate autoconf too, but I thought
that work (kernel feature testing in autoconf) has already been done,
right?

I'm not trying to sabotage anything, I just don't want the maintaince of
a zillion HAVE_ macros to slowly overrun us until we drown under the
weight.  All to support some looney, ill-informed vendor that can never
get around to submitting their driver to mainline.

And as for that "policy", it's been stated in public by Andrew and
Linus and me (if I count for anything, doubtful...) a number of
documented times.

I understand that, but for stuff like that, isn't it easier to just test
for VERSION?  Or use autoconf?

That was because of the backport mess that 2.4 went through and vendor
kernels, right?

What long development cycle?  The out-of-the-tree stuff?  Or the kernel
development stuff?

My main issue is when would we ever be able to remove such HAS macros?

And who specifically will be testing for these HAVE_COMPAT_IOCTL and
HAVE_UNLOCKED_IOCTL macros?  Will that code make it into the main tree
ever?  If not, why not?

Do you mean to add

wall_jiffies +=  (ctime - sleep_start) * HZ;

or an equivalent at the end of timer_resume()?  I did and it helped a little.  
With it, the box hangs while executing device_resume() in swsusp_write().  
Without it, the box hangs earlier.

Still, it's sleep_start that has a wrong value, apparently (it shouldn't be 
negative, at least), and I see that Nigel has a patch that changes 
__get_cmos_time() on x86_64.  I'm going to try it in a couple of minutes.

This is a self-correcting system.  If the symbols are so offensive, someone
will get offended and will submit a patch to delete them at the appropriate
time.  If they're not so offensive then we've nothing to care about.

not me ;) It's two lines of code and makes things much simpler for the
users of our work.  Seems a no-brainer.

And practically speaking, we don't make such fundamental driver-visible
changes _that_ often - if we end up getting buried under a proliferation of
HAVE_FOO macros, then the presence of the macros is the least of our
problems, yes?

Sorry, the "policy" I was referring to was the "out-of-the-tree drivers
are on their own" statement.  Not the use of the HAVE macros.

Ok, but can someone add a section in the feature-removal-schedule.txt
file about when these specific macros will be removed?  They must be
created with some specific use in mind, right?

I sent a group of four patches, I think on Saturday. The first one is
the one Pavel wrongly attributed to me. The other three are mine. I
think you might need all four to get it working right.

Hi,

This patch is intended to fix a bug in timer_suspend() on x86_64 that causes 
hard lockups on suspend with swsusp and provide some optimizations.  It is 
based on the Nigel Cunningham's patches to to reduce delay in 
arch/kernel/time.c.  The patch is against 2.6.10-mm3 and 2.6.11-rc1.  Please

I guess the latter.  Imagine that the stuff already exists in mm tree 
but the merge to the maintree is delayed.  In this case,
KERNEL_VERSION check doesn't work reliably.  But, it's a rare case,
AFAIK.

Here I agree with Greg.  It'll be difficult to remove it once after
added.  Nobody knows whether the external stuff still refers to it or
not...

ALSA, for example, still offers for 2.2, 2.4 and older 2.6 kernels.
So it requires checks for such kernel API changes.  I would do this
via autoconf without problem if HAS_* isn't introduced, though.

Re: [PATCH] fix: macros to detect existance of unlocked_ioctl and compat_ioctl

[ Cc:s trimmed a little ]

Not all users of kernel code are in- or out-of-tree drivers and the
like. E.g. tcsim (from tcng.sf.net) grabs substantial portions of
the traffic control and netlink code and merges them with user
space. It also tries to be compatible with most 2.4 kernels.

For feature tests, I use basically anything that doesn't run away
quickly enough. And I'm sure you want none of *that* kind of code 
anywhere near mainline ;-)

Not that I currently have more troubles with it than usually. I
just want to point out that there are other, strange but legitimate
(at least in the "all shall eventually be GPL" sense) users of the
kernel, who don't mind a friendly environment.

2.6.11-rc1-mm2

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.11-rc1/2.6.11-rc1-mm2/

- There are a bunch of ioctl() and compat_ioctl() changes in here which seem
  to be of dubious maturity.  Could people involved in this area please
  review, test and let me know?

- A revamp of the kexec and crashdump patches.  Anyone who is interested in
  this work, please help to get this ball rolling a little faster?

- This kernel isn't particularly well-tested, sorry.  I've been a bit tied
  up with other stuff.

With this patch, it doesn't build on UP with local APIC :

arch/i386/kernel/nmi.c:130: error: `cpu_callin_map' undeclared (first

i found the fix in the other thread

Re: 2.6.11-rc1-mm2

[Christoph Hellwig]

> +uml-provide-a-release-method-for-the-ubd-driver.patch

This one is bogus.  The driver core doesn't warn about a missing
release method just so that we add an empty one and bloat the kernel.

The object's lifetime rules needs fixing instead, and until that
happens that warning should be kept.

Similar fix is necessary for x86-64, it appears.

security hook missing in compat ioctl in 2.6.11-rc1-mm2

[Michael S. Tsirkin]

Hi!
Security hook seems to be missing before compat_ioctl in mm2.
And, it would be nice to avoid calling it twice on some paths.

Chris Wright's patch addressed this in the most elegant way I think,
by adding vfs_ioctl.

Accordingly, this change:

@@ -468,6 +496,11 @@ asmlinkage long compat_sys_ioctl(unsigne
 
  found_handler:
 	if (t->handler) {
+		/* RED-PEN how should LSM module know it's handling 32bit? */
+		error = security_file_ioctl(filp, cmd, arg);
+		if (error)
+			goto out_fput;
+
 		lock_kernel();
 		error = t->handler(fd, cmd, arg, filp);
 		unlock_kernel();

 from Andy's "some fixes" patch wont be needed.

Chris - are you planning to update your patch to -rc1-mm2?
I'd like to see this addressed, after this I believe logically
we'll get everything right, then I have a couple of small
cosmetic patches, and I believe we'll be set.

Yes, Andrew asked me to wait until mm2 came out, so I'll rediff and send
shortly.

The patch below is against Linus' tree as per Andrew's request.  It will
conflict with some of the changes in -mm2 (including the some-fixes bit
from Andi, and LTT).  I also have a patch directly against -mm2 if anyone
would like to see that instead.

I'm not sure really adding vfs_ioctl is a good idea politically.
I predict we'll see drivers starting to use it, which will cause quite
broken design.

If you add it make at least sure it's not EXPORT_SYMBOL()ed.

Your config boots OK on my P4.  As per usual :(

None whatsoever, sorry.  Guess you could try stripping the .config, see if
you can identify something from that.

Did you try early printk?

What does this mean, btw?  Can you be more specific about where it gets

If you mean that it actually prints no messages at all then yeah, early
printk.  One suspect would be the kexec patches which play with boot-time
memory layouts and such.

Make sure that CONFIG_PHYSICAL_START is 0x100000.

x86-vmlinux-fix-physical-addrs.patch, perhaps..

It says decompressing BIOS check successful and then sits there

[PATCH] sched: account rt_tasks as iso_ticks

[Con Kolivas]

[-- Attachment #1.1: Type: text/plain, Size: 254 bytes --]


SCHED_ISO tasks should have their cpu accounting be a proportion of

Add ticks consumed by rt_tasks to the iso_ticks variable and comments.

reiser4 core patches: [Was: [RFC] per thread page reservation patch]

[Vladimir Saveliev]

Hello

[per thread page reservation discussion is snipped]

> And the whole idea is pretty flaky really - how can one precalculate how
> much memory an arbitrary md-on-dm-on-loop-on-md-on-NBD stack will want to
> use?  It really would be better if we could drop the whole patch and make

ok, we will change reiser4 to keep its pool of preallocated pages
privately as Andi suggested. This will require to have
reiser4_find_or_create_page which will do what find_or_create_page does
plus get a page from the list of preallocated pages if alloc_page
returns NULL.

So, currently, reiser4 depends on the core patches listed below. Would
you please look over them and let us know which look reasonable and
which are to be eliminated.

reiser4-sb_sync_inodes.patch
This patch adds new operation (sync_inodes) to struct super_operations.
This operation allows a filesystem to writeout dirty pages not
necessarily on per-inode basis. Default implementation of this operation
is sync_sb_inodes.

reiser4-allow-drop_inode-implementation.patch
This EXPORT_SYMBOL-s inodes_stat, generic_forget_inode, destroy_inode
and wake_up_inode which are needed to implement drop_inode.
reiser4 implements function similar to generic_delete_inode to be able
to truncate inode pages together with metadata destroying in
reiser4_delete_inode whereas generic_delete_inode first truncates pages
and then calls foofs_delete_inode.

reiser4-truncate_inode_pages_range.patch
This patch makes truncate_inode_pages_range from truncate_inode_pages.
truncate_inode_pages_range can truncate only pages which fall into
specified range. truncate_inode_pages which trucates all pages starting
from specified offset is made a one liner which calls
truncate_inode_pages_range.

reiser4-rcu-barrier.patch
This patch introduces a new interface - rcu_barrier() which waits until
all the RCUs queued until this call have been completed.
This patch is by Dipankar Sarma <dipankar@in.ibm.com>

reiser4-reget-page-mapping.patch
This patch allows to remove page from page cache in foofs_releasepage.

reiser4-radix_tree_lookup_slot.patch
This patch extents radxi tree API with a function which returns pointer
to found item within the tree.

reiser4-export-remove_from_page_cache.patch
reiser4-export-page_cache_readahead.patch
reiser4-export-pagevec-funcs.patch
reiser4-export-radix_tree_preload.patch
reiser4-export-find_get_pages.patch
reiser4-export-generic_sync_sb_inodes.patch
The above patches EXPORT_SYMBOL several functions. Others may find it
useful if they were exported. 

reiser4-export-inode_lock.patch
Reiser4 used to manipulate with super block inode lists so it needs
inode_lock exported.
We are working now to not need this. But quite many things are based on
it. Is there any chance to have it included?


Thanks

Re: reiser4 core patches: [Was: [RFC] per thread page reservation patch]

[Adrian Bunk]

Hi Vladimir,

a general request:

If you add new EXPORT_SYMBOL's, I'd strongly prefer them being 
EXPORT_SYMBOL_GPL's unless there's a very good reason for an 
EXPORT_SYMBOL.

Not okay.  I though I explained you how to do it instead already?

No idea, but if Dipankar things it's okay it probably is.

> reiser4-reget-page-mapping.patch

probably ok, Andrew?

> reiser4-radix_tree_lookup_slot.patch

Idea is okay, implementation needs work:

__lookup_slot should be called radix_tree_lookup_slot and exported direcly.

radix_tree_lookup should be an inlined wrapper in the header, and kill
the != NULL comparims, it's superflous:

static inline void *radix_tree_lookup(struct radix_tree_root *root,
		unsigned long index)
{
	void **slot = radix_tree_lookup_slot(root, index);
	return slot ? *slot : NULL;

Probably okay, but why do you need both remove_from_page_cache
and __remove_from_page_cache?

ok

ok

this one is nasty.  not your fault though, but why do we even
have global radix-tree preloads instead of pools.  What do you
need it for?

> reiser4-export-find_get_pages.patch

Why don't you use pagevecs instead?

Can't find this one in current -mm

No.  Modules must not look at inode_lock, it's far too much of an
implementation detail.

I recently switched my main box to a x86_64 box and installed the unofficial
debian 'true64' port on it.  I have been running 11-rc2 (with the aa oom patches)
with no real problems.  I decided to try 11-rc2-mm2. 

The first time (with a serial console active) it ended with a panic.  When I enabled
a serial console it stalled.  I used alt+sysrq+T and then rebooted.  Here is the 
log.  There are no extra patches on top of mm2.  I compiled using gcc 3.4, with
a .config based on 11-rc2 using oldconfig.
