Hello Alex Vesker,
The patch 26d688e33f88: "net/mlx5: DR, Add Steering entry (STE)
utilities" from Aug 19, 2019, leads to the following static checker
warning:
drivers/net/ethernet/mellanox/mlx5/core/steering/dr_ste.c:271 mlx5dr_ste_get_miss_addr()
warn: potential shift truncation. '0xff (0-255) << 26'
drivers/net/ethernet/mellanox/mlx5/core/steering/dr_ste.c
267 u64 mlx5dr_ste_get_miss_addr(u8 *hw_ste)
268 {
269 u64 index 270 (MLX5_GET(ste_rx_steering_mult, hw_ste, miss_address_31_6) |
271 MLX5_GET(ste_rx_steering_mult, hw_ste, miss_address_39_32) << 26);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Smatch thinks this needs to be cast to u64.
272
273 return index << 6;
274 }
regards,
dan carpenter
