Subject: Cannot move macvlan interface on top of bonding device
Date: Wed, 17 Sep 2014 08:56:41 -0700	[thread overview]
Message-ID: <CA+HUmGi74nx0zELqXX63nJCNXshTC9AkWoRG5bo6AMHyr_3+fg@mail.gmail.com> (raw)

I cannot move a macvlan interface created on top of a bonding interface
to a different namespace:

# ip netns add dummy0
# ip link add link bond0 mac0 type macvlan
# ip link set mac0 netns dummy0
RTNETLINK answers: Invalid argument
#

This used to work in older releases.
The problem seems to be that commit f939981492 sets NETIF_F_NETNS_LOCAL
on bonding interfaces, and commit 797f87f83 causes macvlan interfaces
to inherit its features from the lower device.

Is there a reason why NETIF_F_NETNS_LOCAL should be inherited from the
lower device
by macvlan interfaces?

Thanks,
Francesco Ruggeri
