Hi,
I am trying to use a realtek r8169 gigabit Ethernet levelone card as a link
between two machines that are cluster using openmosix, However whenever I
try to transfer large amounts of data after 5 secs the connections freezes.
I found a similar older post with an attacked patch to try, I tried it but
the problem remained. Any help ?
I don't want to upgrade kernel to something else as I need openmosix to keep
running.

Regards,
Nicholas Papadakos

I know it's fri^Wsatursday but it does not help if you do not specify which
patch you applied.

At a minimum, you want to upgrade the sources of the r8169 driver up to a
more recent 2.4.x: simply drop a drivers/net/r8169.c from the latest 2.4.x
into your 2.4.24 tree, rebuild and report the result (+ complete dmesg +
lspci -vx + lsmod for my collection please).

Cc: netdev@oss.sgi.com is welcome.

Hello and thank you for your time

I copied the latest r8169.c file from kernel 2.4.28 but it didn't compile at
all giving an error message:

r8169.c: In function `rtl8169_init_board':
r8169.c:683: warning: implicit declaration of function `SET_NETDEV_DEV'

when trying to compile the modules.
Same with 2.4.27

The patch I previously applied was a patch made by you in personal and it
was posted in this mailing list.
The patch name was : r8169-debug.patch and it contained the following.

--- r8169.c-realtek	2004-01-17 14:14:50.000000000 +0100

The following info is for the normal kernel 2.4.24 r8169.c file without the
patch applied as I reverted to it since neither the 2.4.28 or the patched
one didn't work.

I know it's fri^Wsatursday but it does not help if you do not specify which
patch you applied.

At a minimum, you want to upgrade the sources of the r8169 driver up to a
more recent 2.4.x: simply drop a drivers/net/r8169.c from the latest 2.4.x
into your 2.4.24 tree, rebuild and report the result (+ complete dmesg +
lspci -vx + lsmod for my collection please).

Cc: netdev@oss.sgi.com is welcome.

It was just a debug patch, not a fix.

Thanks.

Would your application benefit from larger (> 1500 bytes) frames ?

Hello,

I commented out the line recompiled but still same problem.
I couldn't apply the patch because whenever I tried I got :

patch -p0 < rtl 
patching file drivers/net/r8169.c
Hunk #1 FAILED at 1161.
1 out of 1 hunk FAILED -- saving rejects to file drivers/net/r8169.c.rej

A dump of r8169.c.rej :

I tried to apply the patch both in the older version and in the new one but
nothing.

And yeah values greater than 1500 would improve openmosix a lot a believe.

Thank you for your time,

gcc should spit one message less.

The tabs have been turned into spaces. Either add 'ull' to 0x0badbadbadbadbad
or apply the attached version (don't edit/copy/paste it if you are not sure
that the tabs are preserved).

A backport of the test version of the 2.6.x driver (SG, RX/TX csum, up to ~7000
bytes frames, patch against vanilla 2.4.28) is available at:
http://www.fr.zoreil.com/people/francois/misc/20041205-2.4.28-r8169.c-test.patch

For the curious one, the patchscript version can be found at:
http://www.fr.zoreil.com/linux/kernel/2.4.x/2.4.28

It compiles but it is completely untested. You should probably wait a bit until
I verify it is not trivially broken. Otoh, if you have some spare time...

I must be doing something wrong cauz I still get the same error when I try
to apply the patch.

I use :
patch -p0 < r8169-mini-fix.patch 

patching file drivers/net/r8169.c
Hunk #1 FAILED at 1161.
1 out of 1 hunk FAILED -- saving rejects to file drivers/net/r8169.c.rej

  }

I saved the file from my windows machine (outlook 2003) to a samba share on
the machine needed to be patched. 
I don't believe that has anything to do with it, right ?

When commenting the line out the module did compile but It still connection
froze after a while like before.

I tried to apply the patch in both kernel versions same result.
Am I missing something ?

Thank you for your patience

The patch was fine when it left my MUA.

It does not freezes after a few packets (say 64), right ?

Can you triple check that you ran the right module (compilation in the adequate
directory, modules_install, module stat and such) ?

> I tried to apply the patch in both kernel versions same result.
> Am I missing something ?

You can try the untested attached files (no warranty). A failure with the 2.4.28
version of the r8169 driver is something new. Can you send a description of the
computer + complete dmesg + lspci -vx + ifconfig before/after freeze +
/proc/interrupts contents before/after connection freeze ? Does the connection
recover if you ifconfig it down/up ? Same thing after rmmod/modprobe ?

[unstable backport of the r8169 driver]

Nicholas, can you give a try at the patch below against vanilla 2.4.28 ?
http://www.fr.zoreil.com/people/francois/misc/20041209-2.4.28-r8169.c-test.patch

This patch does not trivially crash and you should be able to set the
mtu around 7200 bytes.

The detail of the (43) patches is available at:
http://www.fr.zoreil.com/linux/kernel/2.4.x/2.4.28/r8169.
