Subject: [net 11/11] net/mlx5e: Fix memleak in mlx5e_create_l2_table_groups
Date: Thu, 7 Jan 2021 12:28:45 -0800 [thread overview]
Message-ID: <20210107202845.470205-12-saeed@kernel.org> (raw)
In-Reply-To: <20210107202845.470205-1-saeed@kernel.org>
From: Dinghao Liu <dinghao.liu@zju.edu.cn>
When mlx5_create_flow_group() fails, ft->g should be
freed just like when kvzalloc() fails. The caller of
mlx5e_create_l2_table_groups() does not catch this
issue on failure, which leads to memleak.
Fixes: 33cfaaa8f36f ("net/mlx5e: Split the main flow steering table")
