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.

Please be less cryptic.

What behaviour are you expecting to see?

How does the current behaviour appear to be incorrect?

What was the behaviour in previous kernels?  (Which version?)

What actual probelms are observable?  Oops?  Hang? Corruption?  Nothing?

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.

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.

Re: Linux v2.6.16-rc6

On recent kernel 2.6.15.6 (or any 2.6.15.x) and latest testing
2.6.16-rc6 libata detects and sets wrong UDMA modes for one of the
SATA-1 drives. This seems to be a bug.

My setup is as follows:

ASUS A8N-SLI-Premium Nforce4 mainboard
AMD Athlon X2 CPU running SMP
GCC 3.3.6
Slackware 10.2 Linux

The drives are used in RAID1 array (dmraid), they are WDC-WD2000JD
series purchased few months apart. Sata is compiled in the kernel as
module sata_nv and functions properly, no errors or any other anomalies
were noticed but the UDMA mode detection seem wrong on the second drive.

Drive one reports ata3: dev 0 configured for UDMA/100 while drive two
ata4: dev 0 configured for UDMA/133

Below is the full snippet of libata detection from dmesg:

This bug report is still somewhat unclear.

I belive the modes should say DMA100 because UDMA133 would be mode ATA-7
and DMA100 ATA-6 mode. This is the info i get from hdparm -I on the ata3
drive: DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5

while on the ata4 one:  DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3
udma4 udma5 *udma6

The thing is that the older drive is the one with the mode being set at
133 while the newer with mode 100. I belive they come from the same
factory but do carry different firmware revisons.

I also tried the drives on sata_sil (sil3114) controller and they show
the same modes being detected:

I also see a difference with the transfer rates from hdparm -Tt:

ata3 drive (mode UDMA100) shows:

Timing buffered disk reads:  172 MB in  3.00 seconds =  57.30 MB/sec

while ata4 drive (mode UDMA133) shows:

Timing buffered disk reads:  118 MB in  3.03 seconds =  38.96 MB/sec

At this point is this due to drive capabilites in regards to modes
supported, broken drive? or libata code bug? I am trying to be as clear
as possible, anything else i should provide?

Thanks,

Paul B.

Jeff, thank you for confirming that everything looks correct. Next time
i will be buying matching drives at the same time :-).

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);
    }

Just a little cosmetic-o: is it really "SStatus" or should it be "Status"?

  UDMA4 = 66

  UDMA6 = 133

Has afaics nothing to do with "ATA-5" or -6 or -7 as reported by smartctl 
"ATA version".

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

Since they are the same drive modulo firmware, you might contemplate 
upgrading all to the same level. NOTE: that's just a comment, not a 
recommendation.

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.

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.
