Subject: Re: [dpdk-stable] [PATCH] net/mlx5: fix flow tables double release

From: Bing Zhao
> In the function mlx5_alloc_shared_dr(), there are various reasons to result in
> a failure and error clean up process. While in the caller of mlx5_dev_spawn(),
> once there is a error occurring after the mlx5_alloc_shared_dr(), the
> mlx5_os_free_shared_dr() is called to release all the resources.
> To prevent a double release, the pointers of the resources should be
> checked before the releasing and set to NULL after done.
> In the mlx5_free_table_hash_list(), after the releasing, the pointer was
> missed to set to NULL and a double release may cause a crash.
> By setting the tables pointer to NULL as done for other resources, the double
> release and crash could be solved.
