Subject: [v2 net 08/12] net/mlx5e: Fix skb memory leak when TC classifier action offloads are disabled
Date: Thu, 23 Dec 2021 11:04:37 -0800 [thread overview]
Message-ID: <20211223190441.153012-9-saeed@kernel.org> (raw)
In-Reply-To: <20211223190441.153012-1-saeed@kernel.org>
From: Gal Pressman <gal@nvidia.com>
When TC classifier action offloads are disabled (CONFIG_MLX5_CLS_ACT in
Kconfig), the mlx5e_rep_tc_receive() function which is responsible for
passing the skb to the stack (or freeing it) is defined as a nop, and
results in leaking the skb memory. Replace the nop with a call to
napi_gro_receive() to resolve the leak.
Fixes: 28e7606fa8f1 ("net/mlx5e: Refactor rx handler of represetor device")
