Hi Canonical
This issue with the bnx2x driver exists in the all 4.4. kernels
including the current stable (4.4.36). If 16.04 will continue to
support a 4.4. kernel we need the following patch included in a kernel
build. I am

I found the root of the problem in the bnx2x driver. If the interface is down
when it is slaved to the bridge it returns -EFAULT when attempting to add a vid.

I traced the probolem to __vlan_vid_add(), this code snipit:
/* Try switchdev op first. In case it is not supported, fallback to
* 8021q add.
*/
err = switchdev_port_obj_add(dev, );
if (err == -EOPNOTSUPP)
return vlan_vid_add(dev,

I can reproduce the problem using the following steps:
brctl addbr boom
brctl stp boom off
brctl addif boom enP2p1s0f3
brctl delif boom enP2p1s0f3
enP2p1s0f3 is a port on a bnx2.
The Oops will occur when "brctl delif" is run.

Tested with 4.8.0-27 from proposed. With this kernel, the vlan filtering init
appears to have been successful, so br->vlgrp was not NULL on shutdown.

Reversed mirrored as we can still replicate this with 4.4.0-47. I'll give the
proposed 4.8 kernel a try later today.
Regardless of whether the bnx2x vlan filter init error is resolved, it
seems that the nbp_vlan_flush() routine
7 matches
