unsupported OVS_ACTION_ATTR_SET attribute 0 on coreOS 877.1.0

[enxebre]

Hi,
I am having unsupported OVS_ACTION_ATTR_SET attribute 0 on coreOS 877.1.0
when weave launch
I'm guessing related to openvswitch changes on linux 4.3 https://lwn.net/Articles/662714/

weave version 1.4.1
coreOS 877.1.0

Thanks

Interesting, I don't get that when I try.

Could you supply details of the commands used to launch, plus full logs from docker logs weave?

[bboreham]

On further testing, I do get something similar if I stop then re-launch weave:

core@ip-172-31-46-228 ~ $ ./weave launch-router 172.31.46.229

core@ip-172-31-46-228 ~ $ ./weave launch-router 172.31.46.229
The weave container has died. Consult the container logs for further details.
core@ip-172-31-46-228 ~ $ docker logs weave

In this situation, weave reset then weave launch lets it work again, for me.

Seems similar to weaveworks/go-odp#4

@bboreham weave reset then weave launch works
Thanks

Might be of interest that I couldn't reproduce this in my VM running kernel 4.4rc8. I had to reboot it into 4.3 to reproduce.

So I wonder if this is not due to new CT attributes in 4.3 as I had assumed, but rather is related to this: http://thread.gmane.org/gmane.network.openvswitch.devel/56655

Seems to have been introduced by torvalds/linux@fc4099f

While transitioning to netdev based vport we broke OVS feature [...]

and fixing that caused this breakage.

(thanks for info @rade)

See comments on weaveworks/go-odp#4. Should be fixed now with an updated go-odp.

[bboreham]

@dpw I think you might have meant weaveworks/go-odp#5. Commits are weaveworks/go-odp@5d06488 and weaveworks/go-odp@c794b8c, thanks!

Fixed by weaveworks/go-odp@c794b8c.
