Hello,
since 3.0.6 I get many "eth0: hw csum failure" messages in dmesg
followed by a call trace (see at the end). 3.0.4 is OK, 3.1.1 is not.
When I revert the "bridge: Pseudo-header required for the checksum of
ICMPv6" commit, 4b275d7efa1c4412f0d572fcd7f78ed0919370b3, in 3.1.1,
the messages would not occur.
I have two sky2 interfaces bridged together and I use IPv6, but not
MLD. Most of the time only one interface is connected, the message
occurs for either of them. Another machine with bridged e1000 and
r8169 interfaces is OK even without the revert.
Let me know, if more information is needed to create the correct fix.

Hi,
I re-tested the checksum code, both CHECKSUM_NONE and CHECKSUM_COMPLETE
cases are OK. Maybe the bug is related to sky2.

There are three types of receive checksumming:
1. Hardware does not do checksumming (CHECKSUM_NONE)
2. Hardware validates checksum (CHECKSUM_UNNECESSARY)
3. Hardware computes sum of bytes in skb (CHECKSUM_COMPLETE)
Most hardware does #2, but sky2 uses #3.
For the second case, the hardware does not look at headers but only
reports the one's complement value in ip_summed. It is up to the
protocol layers to adjust accordingly. This means if data is removed
or added the checksum needs to be adjusted.

I think this is what is necessary, please test.
Subject: bridge: correct IPv6 checksum after pull
Bridge multicast snooping of ICMPv6 would incorrectly report a checksum problem
when used with Ethernet devices like sky2 that use CHECKSUM_COMPLETE.
When bytes are removed from skb, the computed checksum needs to be adjusted.

Hello,
with the patch on top of 3.1.1 I no longer get the "hw csum failure"
message. I don't know how to test IPv6 multicast, but IPv6 ND and
SLAAC is correctly passing through the bridge.
Thanks!

Applied, thanks Stephen.

Hi,
[reference: http://bugs.debian.org/609994]
I have a Marvell ethernet controller which presents some failures when
'rx checksumming' is enabled,
here is the model:
$ lspci -vvs 03:00.0
03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E
Gigabit Ethernet Controller (rev 15)
Subsystem: Micro-Star International Co., Ltd. Marvell 88E8053
Gigabit Ethernet Controller (MSI)
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B- DisINTx+
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 32 bytes
Interrupt: pin A routed to IRQ 44
Region 0: Memory at fdbfc000 (64-bit, non-prefetchable) [size=16K]
Region 2: I/O ports at 7c00 [size=256]
[virtual] Expansion ROM at fda00000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: sky2
At first I thought it was due to the MTU size, so I tested different
values but unfortunately without positive effect.
Overall this issue appears randomly when the incoming traffic is high. I
tested 2.6.32, 3.1.1, and 3.2-rc3, sadly
all are affected. Finally, the only way to avoid those failures is to
disabled 'rx checksumming' (ethtool -K ethX rx off).
Here is the stack trace:

This isn't really a hardware checksum failure.
Your problem is deeper than that. The internal parts of the chip are not
communicating correctly. The "hung mac" is a problem only occurs if the PCI
is really stuck. There may be a timing issue on your motherboard, or the BIOS
isn't setting up the device properly. The timing then gets messed up between
the end of frame status and the PCI shared memory region. Turning checksum
off masks the problem, but the status is probably still corrupt.
In either case the problem is beyond the ability of the driver to fix or workaround.
Your best bet is to see if there is a BIOS update, or replace the hardware.

IMO, turning checksum off does more than masking the problem because it
prevents the
connection to stop working or even freeze the system.

Sadly the last BIOS update was in 2006, so I don't think I can rely on
the manufacturer.
But again, deactivate the capability of checksum by NIC hardware makes
the interface stable since March.
