Severity: normal
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I have started to get these warnings from time to time after upgrading to a squeeze kernel
with the backported new version of the e1000e driver:

The frequency is low (once a week or less), but AFAIK this is a regression from the old driver. I
cannot remember to have seen any such warnings with earlier squeeze kernels.
The warning is followed by a couple of reset:
Nov 21 12:35:52 canardo kernel: [157692.873860] e1000e 0000:04:00.1: eth1: Reset adapter
Nov 21 12:37:02 canardo kernel: [157763.525692] e1000e 0000:04:00.1: eth1: Reset adapter
Nov 21 12:37:52 canardo kernel: [157814.218261] e1000e: eth1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None
I did not watch this in action myself, but both PPPoE sessions running over this
interface timed out at the same time, so I assume that the interface actually was
down for 2 minutes here due to whatever caused the warning:

Note: I've replaced the kernel log below with a little more relevant cutout from /var/log/dmesg. The
bug script just captured a lot of packet tracing I've got running...

I have started to get these warnings from time to time after upgrading to a squeeze kernel
with the backported new version of the e1000e driver:

The frequency is low (once a week or less), but AFAIK this is a regression from the old driver. I
cannot remember to have seen any such warnings with earlier squeeze kernels.
The warning is followed by a couple of reset:
Nov 21 12:35:52 canardo kernel: [157692.873860] e1000e 0000:04:00.1: eth1: Reset adapter
Nov 21 12:37:02 canardo kernel: [157763.525692] e1000e 0000:04:00.1: eth1: Reset adapter
Nov 21 12:37:52 canardo kernel: [157814.218261] e1000e: eth1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None
I did not watch this in action myself, but both PPPoE sessions running over this
interface timed out at the same time, so I assume that the interface actually was
down for 2 minutes here due to whatever caused the warning:

Note: I've replaced the kernel log below with a little more relevant cutout from /var/log/dmesg. The
bug script just captured a lot of packet tracing I've got running...

So far as I'm aware, if the TX watchdog fires it indicates one of:
1. A bug in the driver, firmware or hardware caused the hardware
transmit queue to stop.
2. A bug in the driver, firmware or hardware meant that the kernel was
not notified of link-down or another interruption that is expected to
stop the hardware transmit queue.
3. Transmission is being continually blocked by (full-duplex link) pause
frames or (half-duplex link) collisions. This may occur due to a switch
misconfiguration or inconsistent configuration between switch and host.
High levels of traffic or specific traffic patterns that overload the
CPU should never cause this to happen. As the primary maintainer of
another Linux network driver, I have to treat every 'TX watchdog' report
as a bug unless it falls into case 3.
So I don't want to just forget this either. But if you can't reproduce
it, it may be difficult to track down.

This may very well be an example of case 3. The failing interface is

NOTE: switch counters have unfortunately been reset since the event.
The host network configuration is rather unusual, and may seem
unnecessarily complex (but I have my reasons for most of this - I've
just forgotten them :-)
The eth1 interface is bridged with a tap interface connected to a VDE
switch running on the host. Both the physical and virtual switch ports
are configured as trunks and a number of VLAN interfaces are put on top
of the bridge interface:
bjorn@canardo:~$ brctl show
bridge name bridge id STP enabled interfaces
br0 8000.0015171e5e35 no eth1
tap0
canardo:/tmp# cat /proc/net/vlan/config
VLAN Dev name | VLAN ID
Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
br0.1 | 1 | br0
br0.7 | 7 | br0
br0.90 | 90 | br0
br0.93 | 93 | br0
br0.666 | 666 | br0
This way, I can easily connect any combination I want of physical switch
port, virtual switch port and host interface, using only a single cable.
To make this even better, one of the swich ports is connected to a ADSL
modem and I'm running two PPPoE sessions from the same host over br0.90
(the modem is of course an untagged port in VLAN 90).
The packets causing the problem were dummy (probably completely empty)
IPv6 packets addressed to a large number of non-existent hosts within a
single /64. The packets came in over ppp1 running over the ADSL line,
and would be routed out on br0.1.
This probably made the host send a lot of neighbour discovery icmp
packets out br0.1, which would be split out to a number of untagged
ports in VLAN 1 on both the virtual and the physical switch. At least
one of these ports are configured for half-duplex 10Mb/s. I assume that
will limit the possible multicast traffic in this VLAN to 10Mb/s as
well.
The ADSL line is 12Mb/s, and the incoming packets could actually be
smaller than the neighbour discovery packets, so I believe it's feasible
that the triggered neigbour discovery traffic exceeded what the switch
was capable of forwarding in this case.
The real unanswered question is: Will the switch send pause frames in
this case? It is of course capable of handling a whole lot more of
traffic, just not more multicast traffic for this sinlge VLAN.

It would of course be very interesting to watch the switch counters
while doing this, and also seeing if this is reproducible on a VLAN with
only gig ports, or even with only 100Mb/s ports.
Thanks for your feedback. I realized that I should research the problem
better, but I just didn't the time to do that properly when I discovered
that it was more than the simple driver regression I initially thought
it was. Your list of possible reasons made it much easier to guess what
could be going on.

The configuration looks fine to me.

OK.
It does not look like I'm able to reproduce this either. I am only
able to trigger the expected
"Neighbour table overflow."
and a few additional
"ICMPv6 ND: ndisc_build_skb() failed to allocate an skb, err=-11."
but no TX watchdog.
