net/mlx5: Ethernet resource handling files
Hello Amir Vadai,
The patch afb736e9330a: "net/mlx5: Ethernet resource handling files" from May 28, 2015, leads to the following static checker warning:
drivers/net/ethernet/mellanox/mlx5/core/en_flow_table.c:726 mlx5e_create_main_flow_table()
error: potential null dereference 'g'. (kcalloc returns null)
drivers/net/ethernet/mellanox/mlx5/core/en_flow_table.c
719 static int mlx5e_create_main_flow_table(struct mlx5e_priv *priv) 720 {
721 struct mlx5_flow_table_group *g;
722 u8 *dmac;
723
724 g = kcalloc(9, sizeof(*g), GFP_KERNEL);
It should check for allocation failure.
725 726 g[0].log_sz = 2; 727 g[0].match_criteria_enable = MLX5_MATCH_OUTER_HEADERS; 728 MLX5_SET_TO_ONES(fte_match_param, g[0].match_criteria, 729 outer_headers.ethertype); 730 MLX5_SET_TO_ONES(fte_match_param, g[0].match_criteria, 731 outer_headers.ip_protocol); 732
regards,
dan carpenter
