Subject: [dpdk-dev] [PATCH] net/mlx5: fix missing attribute size for drop action
Date: Wed, 10 Jan 2018 09:50:38 -0800 [thread overview]
Message-ID: <20180110175038.34374-1-yskoh@mellanox.com> (raw)
Adding the size of ibv_flow_spec_action_drop is missing. This can cause
overflow when converting rte_flow to ibv_flow and thus corrupt memory.
Fixes: 8086cf08b2f0 ("net/mlx5: handle RSS hash configuration in RSS flow")
