[Kernel-packages] [Bug 1679823] Re: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49, xenial-hwe)

[Thiago Martins]

I'm also expecting this on Xenial ASAP!

I'm using OpenStack with OVN, and the OpenFlow rules does not work with
Kernel 4.4! And MTU does not work with 4.8!

Very bad situation...   :-(

Also expecting the fix for:

https://bugs.launchpad.net/ubuntu/+source/kernel-package/+bug/1685742

...in one shot!

[Kernel-packages] [Bug 1679823] Re: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49, xenial-hwe)

[H.-Dirk Schmitt]

@martinx - To mitigate the problem I've dropped temporally jumbo frames
from the configuration of my servers.

Hopefully the bug will be fixed also for xenial-hwe and not only for
yakkety ;-)

I agree that this is a *blocker* for xenial.

4.8.0-46:  all OK
4.8.0-49:  all interfaces fail with "hw max 68"
4.10.0-20: physical interfaces work, openvswitch bridges fail with "hw max 1500"

[Kernel-packages] [Bug 1679823] Re: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49)

[Jesse Sung]

@jsalisbury: I figured it out...

We're talking about two issues here.

The first one is unable to set MTU larger than 1500 on some devices.

Commit e84f31d (yakkety), "net: centralize net_device min/max MTU
checking", introduced net_device.min_mtu and net_device.max_mtu. These
values will be checked before net_device_ops.ndo_change_mtu().

Then the second commit 04db90d (yakkety) set the default value of
min_mtu to ETH_MIN_MTU(68) and max_mtu to ETH_DATA_LEN(1500), removed
*most* of the ndo_change_mtu() callback, and initialize min_mtu/max_mtu
in each driver if it should be something different than the default
values.

Here I say most because intel drivers are not modified by this commit.
Intel drivers are handled by commit 91c527a5. My e1000e works properly
after this commit is merged. For bonding devices it's commit 31c0541.

The second issue is it shows
"Invalid MTU 9000 requested, hw max 68"
instead of 
"Invalid MTU 9000 requested, hw max 1500".

This is a typo in commit 04db90d and can be fixed by commit a0e65de.

A test kernel with 91c527a5, 31c0541, and a0e65de merged can be found at

Thanks, Jesse.  I'll investigate further.  I'll probably try to
reproduce the bug to make debugging faster.

[Kernel-packages] [Bug 1679823] Re: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49)

[Joseph Salisbury]

After a review, Yakkety did get the following commits via other bug
reports:

d37117d ethernet: use net core MTU range checking in more drivers
6426a88 net: use core MTU range checking in virt drivers
89110d9 net: use core MTU range checking in virt drivers
e84f31d net: centralize net_device min/max MTU checking
fe5473b hv_netvsc: remove excessive logging on MTU change


This changed the MTU checking in some places and not all.  I think commits 
91572088e3f and 3331aa378e9b are needed.

I built a V2 Yakkety test kernel with these two commits.  It can be
downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1679823/

Can folks affected by this bug give this kernel a test?

Thanks in advance!

[Kernel-packages] [Bug 1679823] Re: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49)

[Joseph Salisbury]

It appears commit 3331aa378e9 fixes commit 91572088e3fd.  However,
commit 91572088e3fd was introduced in v4.10-rc1 and not cc'd to stable.
The Yakkety 4.8 kernel never had commit 91572088e3fd applied.  That
explains why my test kernel did not fix this bug.

Comment #6 says that this same issue happened when upgrading from
4.8.0-46 to 4.8.0.49.  The 4.8 regression must have been due to a
different change.  I'll investigate and respond shortly.

[Joseph Salisbury]

Thanks for the testing feedback on my test kernel.  I suspect more than
just commit 3331aa378e9bcbd0d16de9034b0c20f4050e26b4 is needed.
dev->max_mtu being set to ETH_MAX_MTU must be needed in other spots.
I'll investigate and post another test kernel shortly.

[Kernel-packages] [Bug 1679823] Re: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49)

[Joseph Salisbury]

Can folks affected by this bug see if it is fixed with the kernel posted
in comment #12?  To test that kernel you would need to install both the
linux-image and linux-image-extra .deb packages.  You should see this
bug number in the output of uname -a if it the kernel is installed and
booted.

[Kernel-packages] [Bug 1679823] Re: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49)

[Thiago Martins]

I was experiencing issues with OpenStack deployed with Networking OVN
and just saw this message in my dmesg:


---
[   12.241706] 8021q: adding VLAN 0 to HW filter on device eno2
[   15.077293] eno2: Invalid MTU 9000 requested, hw max 68
---

And the IP of my eno2.600 VLAN is gone! So, the Instances can't ping
each other because that is where my data path (GENEVE / VXLAN) tunnels
are created on!

How a bug like this ended up into an LTS release?   :-(

[goldyfruit]

Still having and issue, for the physical interface it's working as
expected but for virtual interfaces I got the same error.

I'm trying to change MTU on an OpenVswitch interface in a kernel
namespace. If I switch back to 4.8.0-46 everything is OK.

[Kernel-packages] [Bug 1679823] Re: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.10 (or 4.8.0-49)

[Joseph Salisbury]

I built a Yakkety test kernel with a pick of commit
3331aa378e9bcbd0d16de9034b0c20f4050e26b4.  The test kernel can be
downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1679823/

Can folks affected by this bug give this kernel a test?

Thanks in advance!

[Joseph Salisbury]

The fix to this bug is in the Ubuntu-4.10.0-15.17 kernel.

I'll build a 4.8 test kernel with the patch and post a link to it
shortly.
