Linux v2.6.16-rc6

Linux v2.6.16-rc6

[Linus Torvalds]

[-- Attachment #1: Type: TEXT/PLAIN, Size: 16311 bytes --]


Ok, we're getting closer, although the 2.6.16 release certainly seems to 
drag out more than it should have.

Some of the worrisome bootup problems seem to have been resolved to a 
stupid build-time race, where we just generated an empty version string. 
Oops. 

The diffstat shows that the largest changes here are the ia64 defconfig 
updates, much of the rest really is pretty small, but all over the map. 
Some ocfs2 and 9pfs fixes and updates, and various driver and networking 
fixes.

The ShortLog (appended) gives a pretty good picture of it,

		Linus

It is a problem with the remote TCP implementation, it is
illegally advertising a smaller window that it previously
did.

Is this something that should be logged though?  I get these messages
all the time on my mirror server.  It isn't like I can do anything about
it.  If Linux is generous in what it accepts and can handle it, what is
the logged error for?

I have been seeing these since the 2.4 era (possibly 2.2).

Unless this is something that just started with 2.6.15-rc6 then it's OT
for this thread.

on 2005/10/27, Herbert Xu provided a patch merged in 2.6.14 to fix some
erroneous occurences of this message (some of them appeared with Linux
on the other side). It would be interesting to know whether the peer
above is Linux or not, because it might be possible that Herbert's fix
needs to be applied to other places ?

Here comes his patch with his interesting analysis for reference, in
case it might give ideas to anybody.

Cheers,
Willy

Subject: [TCP]: Clear stale pred_flags when snd_wnd changes
X-Git-Tag: v2.6.14
X-Git-Url: http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2ad41065d9fe518759b695fc2640cf9c07261dd2

[TCP]: Clear stale pred_flags when snd_wnd changes

This bug is responsible for causing the infamous "Treason uncloaked"
messages that's been popping up everywhere since the printk was added.
It has usually been blamed on foreign operating systems.  However,
some of those reports implicate Linux as both systems are running
Linux or the TCP connection is going across the loopback interface.

In fact, there really is a bug in the Linux TCP header prediction code
that's been there since at least 2.1.8.  This bug was tracked down with
help from Dale Blount.

The effect of this bug ranges from harmless "Treason uncloaked"
messages to hung/aborted TCP connections.  The details of the bug
and fix is as follows.

When snd_wnd is updated, we only update pred_flags if
tcp_fast_path_check succeeds.  When it fails (for example,
when our rcvbuf is used up), we will leave pred_flags with
an out-of-date snd_wnd value.

When the out-of-date pred_flags happens to match the next incoming
packet we will again hit the fast path and use the current snd_wnd
which will be wrong.

In the case of the treason messages, it just happens that the snd_wnd
cached in pred_flags is zero while tp->snd_wnd is non-zero.  Therefore
when a zero-window packet comes in we incorrectly conclude that the
window is non-zero.

In fact if the peer continues to send us zero-window pure ACKs we
will continue making the same mistake.  It's only when the peer
transmits a zero-window packet with data attached that we get a
chance to snap out of it.  This is what triggers the treason
message at the next retransmit timeout.

These should be reverted.  They return success from initcalls when they
should report failure.  In the mmtimer case this is a real bug as it can
be modular, in others it's just cosmetic but provides people wrong examples
to cut & paste from.

If you do not want to see these messages, simply set TCP_DEBUG to 0 in
include/net/tcp.h. Or simply stop logging everything on level debug, which is
worse as it affects all debug kernel output.

Jiri, why did you create a kernel.org bugzilla bug with almost no
information in it?

Anyway, this is the first I've heard of this, more information is
needed to help track it down.  How about the contents of /sys/class/dvb/ ?

We had the three psmouse regressions below in 2.6.16-rc5.

Duncan already stated that this patch fixed (more exactly: works around) 
his problems.

Does anyone still observe a psmouse regression in 2.6.16-rc6 compared 
to 2.6.15, or is everything fine now?

Do you want all the drivers that just return pci_register_driver(&foo)
to be changed as well?  I haven't heard a compelling argument either way,
but there are certainly many drivers that return 0 when they successfully
register a driver that didn't find any devices, e.g., 

    static int __init serial8250_pci_init(void)
    {
        return pci_register_driver(&serial_pci_driver);
    }

Hello,

sorry for that, I expected Tom to help us track this down -- he has this
problem, but he haven't replied yet. Nobody else is complaining, would we defer

Stradis is not a DVB driver. AFAIK it uses V4L devices.

http://bugzilla.kernel.org/show_bug.cgi?id=6170 and
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=181063
seem to be two totally different bugs. First thing to check
for the Nova-T is dmesg, to see if the device was recognized
at all by the driver, so we know if it is an udev
problem or not.

That's different.  The pci drivers support hotplug.  The ia64-specific
drivers only driver onboard devices that can't appear at runtime.

[Nathan Laredo]

Stradis does not support my driver.   Please use
http://stradis.nathanlaredo.com/  such as it is now and I'll update it
later.

Secondly, please confirm that the person reporting this bug actually
has the hardware since the driver *will* refuse to load without
hardware installed.

To my knowledge I am currently the only one of about 10 people using
this hardware under linux.

I didn't test vanilla, but i still have:
psmouse.c: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1
psmouse.c: DualPoint TouchPad at isa0060/serio1/input0 - driver resynched.

in -mm (2.6.16-rc6-mm1).
As I cannot reproduce it at will, it is hard to capture useful debug
info (it usually happens once a day).

Apologies for the lack of additional information, this is simply a lack 
of time on my behalf.  My first attempt to bisect 2.6.15 <-> 2.6.16-rc5 
produced a kernel which caused udev to crash (and stop init).  I will 
shift the goalposts and try again.  Once I have the results I will post 
them to bugzilla.  I will also post the contents of /sys/class/dvb as 
requested above.

Thanks,

Tom.

This looks like a problem of the latest sigmatel codec code in
general.  The author of original code is investigating.

Possibly although from an initial look I didn't see anything that
explained it and I still do see a lot of problems with USB serial and
USB error handling that might be USB or serial but predate the changes.

This has been isolated to a USB and/or cdc-acm driver problem
and has nothing to do with the tty changes or ppp.

It appears to be a reference counting error resulting in
a released dev object that is passed to sysfs.
We are making progress, and expect some more info
tonight from Bob. Fortunately the error is repeatable
even if the actual error is obscure.

I removed the psmouse.* directive from the rc6 kernel and the keyboard

GregKH just snuffed this one with a tweak to sysfs.
It was a convoluted interaction of usb/tty/sysfs
which was only revealed with slab debug and unplugging
the usb device in an active tty session.

I don't see the bttv fix from Duncan Sands. I realize that similar 
mistakes are in other drivers, but bttv is popular and would benefit 
from getting a fix which works, and several posters have confirmed that 
it really does.

Sound works with this patch but now only through the head phones - no sound 
from built-in speakers. Jack sense doesn't seem to work the other way around 
- removing head phone doesn't enable speaker output.

Let me know if you need any info.

Thanks!

Additionally I get  azx_get_response timeout in dmesg with the new patch.
Sound works ok despite of that though.

  Hi Adrian, Nathan and all,

 If think I might have hit this one! 
I managed to get an oops which showed xfs related functions on the backtrace. 
The process involved was "rm" and the specific stress test was some 32 
paralell kernel builds (each one with "make -j8") on a quad Opteron box with 
a 1 TB xfs filesystem. Preemption was disabled.

 After that the machine was still alive, but an fsck.xfs after a reboot showed 
corruption that I was able to repair with xfs_repair. This was also with an 
almost empty filesystem, hence the similarity with the above bug report.

 This was sometime ago, using the git tree from February 23 and unfortunately 
I didn't record the oops and output from xfs_repair. I'll update my git tree 
tonight, rebuild and retest in hopes to find that oops again. FWIW I managed 
to hit this after some 4 to 6 hours of testing so it shouldn't take too long 
to report back.

 See you later...

Best regards

Claudio Martins

OK - any hints that might lead us toward a test case?

Hmm, fsck.xfs wont report corruption - did you mean xfs_check?

Well, not sure its the same yet - what was your stack trace & did
repair report inodes with nlink==0?

Ah, doh.

That's why jack sensing doesn't work for you.  The jack sensing and
auto-muting requies unsolicited events.

It's likely a problem of ACPI or whatever related with irq routing.

Both reporters said it worked in 2.6.15, so if the regression is related 
to irq routing it should be visible in the dmesg.

Parag, Marcus, please send an email with both a dmesg of 2.6.15 and a 
dmesg of 2.6.16-rc6 (or 2.6.16) attached.

Maybe it doesn't appear on 2.6.15 since the unsolicated events are not
used in the old stac9200 code.

Also, there seem some models that show multiple speaker pins in the
configuration table, and this isn't supposed in the latest code.
This could be another reason of the remaining regression.

Working on this issue right now.

Packeteer manipulates window for shaping. I probably misread/read wrong 
RFC on this but I thought it didn't break any MUST NOTs.

I assume Linux + SFQ reordering packets during window growth would not 
trigger it.
