Hello Pablo, We just posted a v6. We hope that this one will be the good one.
The test this needs to be compiled via: gcc -lnetfilter_conntrack test-conntrack.c -o test
Thanks for the pointer, it helped us a lot, it was not clear before for us how to test it.
We applied patch on top of current net-next HEAD and it looks good for this one (OK: 122 BAD: 0).
Best regards, -- Florent.
