Subject: [PATCH net-next] net: bridge: fix error in br_multicast_add_port when CONFIG_NET_SWITCHDEV=n
Date: Wed, 21 Apr 2021 21:44:20 +0300	[thread overview]
Message-ID: <20210421184420.1584100-1-olteanv@gmail.com> (raw)

From: Vladimir Oltean <vladimir.oltean@nxp.com>

When CONFIG_NET_SWITCHDEV is disabled, the shim for switchdev_port_attr_set
inside br_mc_disabled_update returns -EOPNOTSUPP. This is not caught,
and propagated to the caller of br_multicast_add_port, preventing ports
from joining the bridge.

Reported-by: Christian Borntraeger <borntraeger@de.ibm.com>
Fixes: ae1ea84b33da ("net: bridge: propagate error code and extack from br_mc_disabled_update")
Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com>
