Hi Adi,
> What's my workaround?
You may want your code to first check if the new mbuf resulted from
mbuf_dup() has the same auxiliary mbuf attached to it, and if so
manually copy the auxiliary mbuf and attach it to the new mbuf using
mbuf_aux_add(). That way, when this bug is fixed your code would
still work.

How do I check if the new mbuf resulted from mbuf_dup() has auxiliary
data at all? I couldn't see any accessors in kpi_mbuf.
If there were, then I would have simply queried if there was aux data
attached in the new mbuf, and NULL'ed the aux pointer in the new mbuf,
because my clients for the duplicated mbuf don't care about that aux
data.
Thanks!
