6.14-rc4-mm1/

It's good ole kgdb. FWIW, Tom Rini's version which has been posted
several times to lkml doesn't have this issue.

Con's swap prefetching code

Thanks.

For users testing this, could you please also try larger values in:
/proc/sys/vm/swap_prefetch
Read the current value (it should be in the range of 1-10) and try a value ten
times larger.

It is currently quite gentle in the amount it prefetches, but the code is now
extremely cautious about when to prefetch and I suspect it can prefetch much
more by default, thus intensifying the effect and benefit.

Cheers,
Con

- Lots of i2c, PCI and USB updates
- Large input layer update to convert it all to dynamic input_dev allocation
- Significant x86_64 updates
- MD updates
- Lots of core memory management scalability rework

Compiles and runs here, but noting these messages when ethernet link down:

Excellent. Looks like we actually caught something. Pity we don't have
a stack trace which means that there might be more bugs.

Anyway, here are three patches which should fix this. This should go
into 2.6.14.

Arnaldo, you can pull them from

[NEIGH] Fix add_timer race in neigh_add_timer

neigh_add_timer cannot use add_timer unconditionally. The reason is that
by the time it has obtained the write lock someone else (e.g., neigh_update)
could have already added a new timer.

So it should only use mod_timer and deal with its return value accordingly.

This bug would have led to rare neighbour cache entry leaks.

[NEIGH] Fix timer leak in neigh_changeaddr

neigh_changeaddr attempts to delete neighbour timers without setting
nud_state. This doesn't work because the timer may have already fired
when we acquire the write lock in neigh_changeaddr. The result is that
the timer may keep firing for quite a while until the entry reaches
NEIGH_FAILED.

It should be setting the nud_state straight away so that if the timer
has already fired it can simply exit once we relinquish the lock.

In fact, this whole function is simply duplicating the logic in
neigh_ifdown which in turn is already doing the right thing when
it comes to deleting timers and setting nud_state.

So all we have to do is take that code out and put it into a common
function and make both neigh_changeaddr and neigh_ifdown call it.

[NEIGH] Print stack trace in neigh_add_timer

Stack traces are very helpful in determining the exact nature of a bug.
So let's print a stack trace when the timer is added twice.

I guess at some point I'll try to make the neighbour code more like the
sock one where we have things like sk_reset_timer and sk_stop_timer for
this purpose.

Does that updated patch fixes it ?

Lots of rejects, so I manually applied the relevant part in nv_proto.h.
It worked, though there were warnings:

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.14-rc4/2.6.14-rc4-mm1/
git-ntfs.patch

This is a request for testers for ntfs. 2.6.14-rc4-mm1 contains a
pretty much complete re-write of file write support so some more testers
than just myself would be good before I submit it for inclusion in
2.6.15...

The rewrite means that the following features are now supported:

Given an existing uncompressed and unencrypted file, you can use:

- write(2) to write to the file, including beyond the end of the
existing file, and the file will be extended appropriately. Both
resident and non-resident files are supported. Support for heavily
fragmented files still has some limitations but you will just get an
EOPNOTSUPP error if you hit one. Everything will still be consistent on
the volume. Sparse files can also be written to and holes will be
filled in appropriately.

- truncate(2) and ftruncate(2) to change the size of the file, inlcuding
using open(2) with O_TRUNC flag. As with write(2) there still are some
limitations for heavily fragmented files, and as above, everything will
still be consistent on the volume if you hit an unsupported case.

What this means is that you can now run your favourite editor on an
existing file, e.g. "vim /ntfs/somefile.txt" works fine and you can save
your changes. Also things like running OpenOffice should work to edit
existing MS Office documents but I haven't tried it yet (it should work
as long as OpenOffice does not need to create temporary files in the
same directory as the document).

Still not supported features are creation/deletion of files/directories
and mmap(2) based writes to sparse regions of files. (The mmap(2)
support has not been modified since the last release, only the file
write(2) support was rewritten.)

If you do try it, please let me know how it worked for you! - Thanks a
lot in advance for testing!

Best regards,

Anton

Hi,

To all: There is serious data corruption issue with ntfs in
2.6.14-rc4-mm1 (and ntfs 2.1.25 release in general, not just -mm). Fix
is below. Hopefully this is the only bug!

Hi Anton, not too lucky doing modifications with soffice to word documents.
Saving files is ok but when I reopen the files, the format is lost...
I'll try to recover them from Word.exe

I'm afraid I have bad news, I couldn't boot W2K, I got this message
STOP: C0000221 { checksum image test incorrect }
Something weird, I edited txt file A with vim, then I edited Word File
B with soffice, I close it, then I reopened. I lost format so the file
is not legible but I can see paragraphs from file A in file B!!!!!

I am really sorry about this. )-: You should be able to hopefully fix
windows by booting with the installation CD and going into recovery
console and running chkdsk on the partition. You can also try running
ntfsfix from ntfsprogs and then booting into windows. This may be
sufficient to allow it to do a chkdsk on the partition before it
crashes.

I found a bug that caused corruption of the openoffice document as you
described. The fix is below.

Le Monday 17 October 2005 16:56, vous avez écrit :

i'm package maintainer of kernel26mm in archlinux (i686).
the compiler is gcc 4.0.2 with some bugs fixed it had (from
4.0.3-snapshot).

yes, jsm-tty is built as module, as can be seen from output i posted.
the only difference from 2.6.14-rc4-mm1 and the one i compile is the
applied cleanup patch

2614-rc4-mm-sparse-fixes.patch

that was announced on the mailinglist just after the rc4-mm1 release.

if you need the config, it can be found here:

http://cvs.archlinux.org/cgi-bin/viewcvs.cgi/kernels/kernel26mm/?cvsroot=Extra&only_with_tag=HEAD

i'm willing to apply any patches that would make kernel26mm again compile
all ttys successfully (the last one that did is 2.6.15-rc5-mm1).

thanx + greetings,
Damir

[V. Ananda Krishnan]

Hi all,

Can some one send me pointer(s) to the recent API changes in the tty
layer that has gone in to linux-2.6.14.xxx. As Damir pointed out in his
mail yesterday, currently jsm driver is broken in 2.6.14-rc4-mm1
kernel. I am trying to debug the jsm driver at my end. Any help in
this is appreciated.

You have access to the patches as well as we do. :)

Anyway, the changes are only in the -mm tree for now, not in the
mainline kernel. Look at the patches there, they should be pretty
obvious.

The authors haven't updated it to the new tty buffering API and its the
one driver which is so complex and so abuses the interface [mostly
because the old API was inadequate for it] that I couldn't see how to
fix it and it needers a fixer with hardware and docs.

Alan or Andrew,

Would it be appropriate for me to send in a patch that disabled
CONFIG_SERIAL_JSM in *-mm/arch/ppc64/defconfig for the time being?

As Alan has explained, his flip buffer removal killed serial jsm
(it was already in ill health.)

I trip over it when I try to cross compile all the defconfig's.

My inclination is that it better to make an effort to keep *-mm
compiling for all defconfigs.

If it helps, sure. It looks like those patches will be -mm-only for a
while yet. I haven't actually sat down and worked out how many drivers are
still broken, nor how important they are, but the amount of breakage does
still appear to be considerable.

The only broken driver I am aware of remaining is the jsm driver, and
possibly one or two embedded drivers that the authors simply won't fix
until it goes mainstream.

ISDN was the last big one and I sent fixes for that.

What else is broken ?

Hard to quantify, really. One would need to iteratively disable config
options to generate a complete list. Perhaps a `make -i' will tell?

drivers/serial/sunsab.c is one.

Hi Andrew,
I got the following oops during the boot on my laptop (Compaq Evo N600c).
.config is attached.
Regards,
Brice

Where did get support for IBM TrackPoints into that kernel? It's
certainly not in 2.6.14, and it's not in the -mm patch either ...

That's likely the cause here, since the TP patch probably relies on
non-dynamic allocation semantics.

It was converted but I am aftraid when Greg created sub-class devices
something broke a bit. Do you see the ugly names input core prints?

The "//" stuff you mean? Did I do that?

Not directly. I was trying to make names look "nice" but when you
moved stuff around they stopped being nice ;) Although that name in
front of double "/" - it should not be there... it was supposed to be
"%s as %s/%s", somehow I screwed that up.

Hopefully I'll have some time tonight to investigate further.

A simple:
cat /sys/class/input/input1/event1/name
causes this to happen too.

That's my fault, I'll work on fixing that.

I am confused - the only thing changed is the way you create attributes,
not the way data is accessed. What is the difference and why does it fix
the OOPS?

Because before my patch, any class_device created for the input class,
had the name, phys, and uniq attributes created for them, including the
"simple" class device structures event0, event1, and so on. The kobject
being passed back to those callback functions was not of the same type
of object as input0, input1 and so on. So bad things happened.

I just moved the attribute group out of the class, and created it when
the proper input device was registered. Hm, forgot to uncreate the
group too, I'll go do that now...

Hope this helps,

Oh, I see. That's what you get for mixing devices of different classes
into one class ;)

I agree, it's tough, nasty, and full of horrible issues like this. I
got away with much the same mess with the USB core code where we mix
devices of different types on the same bus, but I wouldn't recommend
ever doing that again.

So, when we move everything over to being only devices, I'll try to make
problems like this impossible to occur, as it's a pain...

Something went wrong under input_devices_read(). Probably culprits cc'ed.

I know this patch doesn't have the proc path, but it does fix an easy
oops that I can generate from sysfs input devices. Can you try it out
to see if it fixes your issue too?

I am confused - the only thing changed is the way you create attributes,
not the way data is accessed. What is the difference and why does it fix
the OOPS?

Thanks!

No sorry, it doesn't fix my oops.

By the way, your patch didn't apply to my rc4-mm1 tree.
The one I had to apply is attached.

I might add some debugging code into my tree to help debugging.
But, you'll have to tell what code and where :)

If you disable CONFIG_PNP, does the oops go away?

Also, does this oops keep you from booting? If not, can you see what
the output of 'cat /proc/bus/input/devices' produces (it should show
what device is dying on us.)

Yes disabling CONFIG_PNP makes it disappear.

Here comes /proc/bus/input/devices from 2.6.14-rc4:

I: Bus=0011 Vendor=0001 Product=0001 Version=ab41

P: Phys=isa0061/input0
H: Handlers=kbd event3

B: SND=6

Without CONFIG_PNP, the last one disappears.

In rc4-mm1, the last one is a little bit different
(Name and Phys fields):

I: Bus=0010 Vendor=001f Product=0001 Version=0100

Not yet, except that PC speaker is one of input devices that does not have

Hi Andrew,
I got the following oops during the boot on my laptop (Compaq Evo N600c).
.config is attached.
Regards,
Brice
IBM TrackPoint firmware: 0x0b, buttons: 2/3

Odd, what userspace program is wanting to see the proc input stuff?

What distro and version of it are you running?

And did this oops happen after init started, or before?

thanks,

My distro is a Debian testing/sid.
hotplug is 0.0.20040329-25
udev is 0.70-2

This occurs after init started.

From what I see, it's during hotplug, when it scans isapnp devices.
hotplug finds PNP0800 in /sys/bus/pnp/devices/00:07/id and then
loads pcspkr. The oops occurs during "modprobe -s -q -q pcspkr"
in the isapnp.rc script.
This script is attached in case there's something specific in Debian.

I don't see how I could investigate further.
Let me know if you have any idea to debug the modprobe.

Regards,
Brice

This one gets me a penguin on the framebuffer, and then dies
with no further textual output.
numlock leds were working, and I could reboot with sysrq.

Single opteron, Matrox G550 AGP framebuffer. There is also
a pci radeon in the machine, but no driver for it as X has
to do int10 initialization first.

Can we get anything useful out of sysrq-p and sysrq-t?

Also, adding initcall_debug to the boot command line might help.

Nothing displayed - the penguin just sits there.
Seems he's not hung, merely waiting for something, even
ctrl+alt+del does a reboot.

Didn't seem to help. I get some text _before_ the penguin
appears, thre last I was able to read before the blackout
and the penguin was something about USB storage.

I had both vgacon and fbcon compiled in. I am retrying with
vgacon only, no framebuffer support, to see if it is a framebuffer
or fbcon problem. This setup worked with 2.6.14-rc3 though.

Tried again without the framebuffer. Still hanging, but more info:

Somewhat silly. There certainly was a console (vgacon) or I wouldn't
be able to read the messages. And if it mounted root, then there certainly
was an init to run also.

SYSRQ T gave me several pages, with no scrollback. Several kernel

kedac R running task
md2 S
md3 S
md0 S
kjournald S

I can provide the full 80x50 page, but I have to write it down by hand
so only if someone actually think it will be useful.

That EDAC thing was new in rc4-mm1, compared to rc3. I am testing
another rc4-mm1 kernel without it. (menuconfig adviced me to say Y
to the new EDAC thing, so I did that initially.)

I see the same effect, with the only difference
that I don't get the kernel panic line.
For me it gets stuck after the "warning-unable to open an initial console"

I'll send you the .config in a seperate mail.

afaik that was done to increase testing.
This thing shouldn't be a config option at all in a final release imo;
the config option as I understand it is there to be able to disable it
during the testing phase in -mm to help diagnose otherwise unexplained
issues.

Maybe by now it's time to remove the config option..

that's not a reason to apply your patch that default-disables the
feature on the upstream kernel. Distributors can pick whichever flavor
they want. E.g. Fedora rawhide has PREEMPT_BKL enabled.

i'm fine with removing the .config option for 2.6.15.

I've been having problems with ipw2200 oopsing at modprobe since
2.6.14-rc2-mm1 (sorry for not reporting before). I use the ipw2200

2.6.14-rc2 is OK (or what was the last OK)? There are no significant
changes in rc2-mm1.

I use only -mm, and skipped 2.6.13-mm3. 2.6.14-rc1-mm1 had some other
oops and I didn't even try ipw2200. So last OK was 2.6.13-mm2 (which
I'm still using now)

...oopsing at modprobe since... are you sure? This seems like an iwlist.

I meant that it oopsed just after I modprobed it. But as it makes a
iwlist just after having been loaded, I guess it is actually in an iwlist.

Hi,

I tested with -rc4 and the problem did not appear.
As for your patch, it just says ---THIS: 0,0 before oopsing.

Hope it helps.

Yes, it really does.

The problem is in git-netdev-all.patch. Somebody rewrote the function:

There are much newer versions of the ipw2200 driver and related ieee80211
stuff available now -- including a 1.07 driver release just this week.

I wonder how long it will be until the 2.6 kernel catches up ?

Yup. There is a BIG problem between ipw and 80211. 80211 is a new code and ipw
is an old one. We don't set perfect_rssi and worst_rssi in ipw and 80211 wait
some other values than 0!

What was the problem to not to add a new version of ipw into kernel?

And what about this fix (at least for the time, until ipw will be updated)?
