Subject: [bug report] net/mlx5: E-switch, Offloads shift ACL programming during enable/disable vport
Date: Wed, 3 Jun 2020 13:34:33 +0300	[thread overview]
Message-ID: <20200603103433.GD1845750@mwanda> (raw)

Hello Vu Pham,

The patch 748da30b376e: "net/mlx5: E-switch, Offloads shift ACL
programming during enable/disable vport" from Oct 28, 2019, leads to
the following static checker warning:

	drivers/net/ethernet/mellanox/mlx5/core/eswitch_offloads.c:1979 esw_create_uplink_offloads_acl_tables()
	error: 'vport' dereferencing possible ERR_PTR()

drivers/net/ethernet/mellanox/mlx5/core/eswitch_offloads.c
  1970  static int esw_create_uplink_offloads_acl_tables(struct mlx5_eswitch *esw)
  1971  {
  1972          struct mlx5_vport *vport;
  1973          int err;
  1974  
  1975          if (esw_use_vport_metadata(esw))
  1976                  esw->flags |= MLX5_ESWITCH_VPORT_MATCH_METADATA;
  1977  
  1978          vport = mlx5_eswitch_get_vport(esw, MLX5_VPORT_UPLINK);

No error checking.

  1979          err = esw_vport_create_offloads_acl_tables(esw, vport);
  1980          if (err)
  1981                  esw->flags &= ~MLX5_ESWITCH_VPORT_MATCH_METADATA;
  1982          return err;
  1983  }

regards,
dan carpenter
