Hi,

We did the 21.02-rc4, but there is still a problem with flow offloading as this was not fixed. The other problems should be fixed now.

Currently we still have these problem:

- IPv6 broken with flow offloading (according to reports, potentially related to hw flow offloading) - PPPoE allegedly broken (according to reports, not fully reproducible, likely related to hw flow offloading too)

I'd like to add that disabling IPv6 with PPP on 21.02 will not fully disable IPv6 as per jow's tip here [1], would be neat if that could be fixed (and backported to a .1, this is not a showstopper for 21.02 final in any way). Just wanted to put it on the radar. An unintentional side effect with a local ISP here is that it breaks IPv4 a well.

Cheers

It could be that this change causes the problems:
https://patchwork.ozlabs.org/project/netdev/patch/20180720130906.27687-3-pa...@netfilter.org/

I do not know how much time and interest I have in debugging and fixing this problem. If someone wants to have a closer look into this problem it would be really nice. even when you can make it easier to reproduce it in a test environment it would be nice.

Should we just release with this as a known problem?

Other than this problem I am not aware of any other critical problem.
