Package: linux-2.6
Version: 2.6.32-38
Severity: important
Tags: ipv6
I have three squeeze servers running:
ii linux-image-2.6.32-5-xen-amd64 2.6.32-38 Linux 2.6.32 for 64-bit
PCs, Xen dom0 support
All three servers have Intel gigabit NICs, but one server uses the
e1000e driver and the other two use the igb driver.
They've been in production for around 6 months now and it seems like
somewhat embarrassingly we've only just now discovered a problem
with IPv6 performance on the two servers with the igb driver.
The problem manifests itself as awful TCP performance to a Xen domU,
on the order of 15-30KB/sec data transfer. Doing the same data
transfer from the server dom0 itself does not show the same issue,
and the expected tens of MB/sec data transfer is achieved.
Here's an example tcpdump from the dom0 host when the problem is
occurring:
# tcpdump -vpni bond0 'host 2a00:801:0:11::2'

2001:db8:0:1f1::8 > 2a00:801:0:11::2: [icmp6 sum ok] ICMP6, packet too big,
length 1240, mtu 1500
2a00:801:0:11::2 is speedtest.tele2.net which helpfully hosts files
like http://speedtest.tele2.net/100MB.zip for testing purposes. The
above is the result of me using wget to download that file from a
domU on this server. The domU is at 2001:db8:1f1:f240::2 and the
dom0 is at 2001:db8:0:1f1::8.
What I'm noticing is the occasional incorrect checksum and "ICMPv6
packet too big" messages seen above around 23:59:00.672905 and
23:59:01.240946 after a packet of length 2856. These do not occur
on the server with the e1000e driver, where all the packets top out
at 1428. They always occur on the two servers with the igb driver
where the poor throughput is observed.
This also does not occur when the IPv6 traffic is sourced on the dom0.
It's only when it's coming from a Xen domU.
I'm wondering if I am hitting something like this:
http://amailbox.org/mailarchive/linux-kvm/2010/2/2/6257539/thread
I have played with disabling and enabling GSO and checksums on every
interface I can (using ethtool), both in dom0 and domUs, and that makes
no difference.
Looking at linux-source-2.6.32 on squeeze, it does not have this
patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8e1e8a4779cb23c1d9f51e9223795e07ec54d77a
although I notice that this commit also touches e1000e where I am
not currently having any problems, even without this commit.
("severity: important" seemed correct because this renders IPv6
effectively unusable for large transfers to/from domUs)
