From 154e62abe9cd07c9b71735d8456a03a7c5251280 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Mon, 10 Dec 2018 12:31:42 +0200 Subject: [PATCH] net/mlx5e: Properly initialize flow attributes for slow path eswitch rule deletion When a neighbour is resolved, we delete the goto slow path rule from HW. The eswitch flow attributes where not properly initialized on that case, hence we mess up the eswitch refcounts for chain zero (the default one). Fix that along with making sure to use semicolons and not commas on that code; Fixes: 5dbe906ff1d5 ('net/mlx5e: Use a slow path rule instead if vxlan neighbour isn't available') Signed-off-by: Or Gerlitz Reviewed-by: Paul Blakey Signed-off-by: Saeed Mahameed --- drivers/net/ethernet/mellanox/mlx5/core/en_tc.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/drivers/net/ethernet/mellanox/mlx5/core/en_tc.c b/drivers/net/ethernet/mellanox/mlx5/core/en_tc.c index e6170ddf2cc4..3b732c02b5e1 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/en_tc.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/en_tc.c @@ -870,9 +870,9 @@ mlx5e_tc_offload_to_slow_path(struct mlx5_eswitch *esw, struct mlx5_flow_handle *rule; memcpy(slow_attr, flow->esw_attr, sizeof(*slow_attr)); - slow_attr->action = MLX5_FLOW_CONTEXT_ACTION_FWD_DEST, - slow_attr->mirror_count = 0, - slow_attr->dest_chain = FDB_SLOW_PATH_CHAIN, + slow_attr->action = MLX5_FLOW_CONTEXT_ACTION_FWD_DEST; + slow_attr->mirror_count = 0; + slow_attr->dest_chain = FDB_SLOW_PATH_CHAIN; rule = mlx5e_tc_offload_fdb_rules(esw, flow, spec, slow_attr); if (!IS_ERR(rule)) @@ -887,6 +887,9 @@ mlx5e_tc_unoffload_from_slow_path(struct mlx5_eswitch *esw, struct mlx5_esw_flow_attr *slow_attr) { memcpy(slow_attr, flow->esw_attr, sizeof(*slow_attr)); + slow_attr->action = MLX5_FLOW_CONTEXT_ACTION_FWD_DEST; + slow_attr->mirror_count = 0; + slow_attr->dest_chain = FDB_SLOW_PATH_CHAIN; mlx5e_tc_unoffload_fdb_rules(esw, flow, slow_attr); flow->flags &= ~MLX5E_TC_FLOW_SLOW; } -- 2.30.2
