Which additional netlink changes from 4.2 did you patch? We still see
the problem with your test program with 4.1.12 which have the
following two patches mentioned by Herbert Xu on this thread.


Sorry, I don't recall, and I no longer have access to the kernel since
I now work for a different company. I do recall that we had to apply
additional patches later, but I don't remember details.

I think it is probably this one:

The original backport is incorrect in 4.1 branch, and it is fixed now.

Yes, overall I would hope that 4.1.y should be up to date and working now.
