Hi Stephen!
System description:
- AOpen i915GMm-HFS, Pentium M 750
- Realtek 8139 PCI Adapter
- The software once was a SuSE 9.2
- kernel: various 2.6.15*, 2.6.16-rc*
The mainboard includes:

The sky2 driver is compiled into the kernel as well as the 8139 driver.
I am connected to the internet via adsl and do use the SuSE Firewall.
8139 with or without SuSEFirewall
=====================
Absolutely no problems.
SKY2 with SuSEFirewall
===============
Initiate or terminate a session: fine
host foo, ping bar, etc do not work,
Domain name lookup seems to be broken.
SKY2 without SuSEFirewall
=================
Seems to work.
Have a look at this part of /var/log/messages:

It seems that the SuSE Firewall locked something ....
I started with kernel 2.6.15-git7, tried 2.6.15.1 and 2.6.16-rc1*.
At the moment I do use a kernel 2.6.15-git7 patched with an updated sky2
(v.013).
I could not find a single working sky2 configuration.
Any ideas?
cu,
Knut

Are you using the full kernel.org kernel, or are you putting sky2 driver into
the SUSE kernel? There are a number of bug fixes related to hardware checksumming
that are in the kernel.org kernel (2.6.15 or later). There was one in ICMP.
These fixes relate to places in the code where a protocol decides to trim a
packet by removing bytes. I am not familiar with the SuSE Firewall. Is it just
standard netfilter modules or additional code?

No SuSE kernels here. I started with kernel.org kernel 2.6.15-git7 and
had those problems. Then I tried 2.6.16-rc3-git3, the most recent kernel
at the time of my original writing. As I had some other problems with
that kernel I had a look at the git tree of Linus and applied all sky2
related
patches to the otherwise unchanged 2.6.15-git7. 2.6.15.1 also was no
solution as sky2 seems to be not available there.

I have to admit that I don´t know enough about the network layers
of the kernel, so here is a list of the network modules loaded (sky2
compiled into the kernel). SuSEFirewall is just standard netfiltering
using those modules.

As said before, rtl8139 does work perfectly well, the same is true
for an identical system with a Via Rhine adapter.

Could you try turning off rx checksumming (with ethtool).
ethtool -K eth0 rx off
There probably still are (generic) bugs in the netfilter code for CHECKSUM_HW
socket buffers.

"ethtool -K eth0 rx off" does cure my problem with sky2.
Anybody is invited to send patches as the problem is 100% reproducible here.

Does it always show up on icmp only?
What are the iptables rules (iptables -L)

Does the problem go away if you disable conntrack by unloading its module?
Please try to capture the offending ICMP packet with tcpdump and show us
what it looks like.

As far as I can see, all my sky2 problems are gone with -K rx off.
So here is more information. I executed the following script:
logger Starting test
logger "Executing ethtool -K eth0 rx off"
ethtool -K eth0 rx off
logger "Executing tcpdump -i eth0 -vv > tcpdumpfile &"
tcpdump -i eth0 -vv > tcpdumpfile &
logger "Executing host www.suse.com"
host www.suse.com
logger "Sleeping 2 seconds"
sleep 2
logger "Executing ping -c 2 195.135.220.3"
ping -c 2 195.135.220.3
logger "Sleeping 2 seconds"
sleep 2
logger "Executing ethtool -K eth0 rx on"
ethtool -K eth0 rx on
logger "Sleeping 2 seconds"
sleep 2
logger "Executing host www.suse.com"
host www.suse.com
logger "Sleeping 2 seconds"
sleep 2
logger "Executing ping -c 2 195.135.220.3"
ping -c 2 195.135.220.3
logger "Sleeping 2 seconds"
sleep 2
logger "Executing ethtool -K eth0 rx off"
ethtool -K eth0 rx off
logger "Sleeping 2 seconds"
sleep 2
logger "killall tcpdump"
killall tcpdump
logger End of test
The first host and ping worked fine, after the ethtool -K eth0 rx on
the host www.suse.com timed out with
;; connection timed out; no servers could be reached
and the ping 195.135.220.3 provoked the stack traces you see in sky2syslog.
I attach the syslog for the time of the test, the output of iptables -L
and the
output of tcpdump as the very long lines included would be hard to read
with linebreaks.
No, I did _not_ delete anything from the tcpdump file.
cu,
Knut

OK, although we can't rule out sky2/netfilter from the enquiry, I've
identified two bugs in ppp/pppoe that may be responsible for what you
are seeing. So please try the following patch and let us know if the
problem still exists (or deteriorates/improves).
[PPP]: Fixed hardware RX checksum handling
When we pull the PPP protocol off the skb, we forgot to update the
hardware RX checksum. This may lead to messages such as
dsl0: hw csum failure.
Similarly, we need to clear the hardware checksum flag when we use
the existing packet to store the decompressed result.

We had a couple of reports of incorrect hardware checksums with
PPPoE. KdF, can you test Herbert's patch (attached again to this
mail) please?

That patch seems to solve all my problems with
sky2 / pppoe / SuSE 9.2 Firewall.
Thanks a lot!

2.6.16-rc2 still misses your patch. Was there a special reason not to
send it
to Linus?

Hi Stephen!

The decreasing time stamp counters are not a sign of delayed printks
but of broken printk timestamping. That means that you probably see
the correct order of printks, but cpu load is increasing fast at that
point ... see my lkml mail about timer problems.

Knut
