From: Yevgeny Kliteynik [ Upstream commit 60e9e82f162ab7399373ff2185119289e4f6dc06 ] If a table has a miss table that was created by 'mlx5hws_table_set_default_miss' API function, its miss_tbl keeps the table that points to it in a list. If such table is deleted, we need to also remove it from the miss_tbl list, otherwise the node in miss_tbl list will contain garbage.

That doesn’t change the earlier conclusion. The patch content and review context came from the local mbox (`20260507_tariqt_net_mlx5_steering_misc_enhancements.mbx`), and the backport recommendation for this 6.18.43 tree remains **YES**. drivers/net/ethernet/mellanox/mlx5/core/steering/hws/table.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/net/ethernet/mellanox/mlx5/core/steering/hws/table.c b/drivers/net/ethernet/mellanox/mlx5/core/steering/hws/table.c index 6113383ae47bb..07a3dd1248c77 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/steering/hws/table.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/steering/hws/table.c @@ -282,6 +282,9 @@ int mlx5hws_table_destroy(struct mlx5hws_table *tbl) goto unlock_err; } + if (tbl->default_miss.miss_tbl) + list_del_init(&tbl->default_miss.next); + list_del_init(&tbl->tbl_list_node); mutex_unlock(&ctx->ctrl_lock); -- 2.53.0
