[dpdk-dev] [PATCH] net/mlx5: fix RSS action validation of queue idx

[Matan Azrad]

From: Dekel Peled
> RSS action validation function checks the queues included in RSS to make
> sure they are valid.
> A Queue is considered valid if the pointer to the queue (item at location
> queue-index of RxQ array) is not a null value.
> The queue indices are not checked. If a large value is entered as queue
> index, using it as an index in RxQ array will result in a pointer to memory out
> of array bounds. If this memory contains a value which is not null, this queue
> will be wrongly considered valid.
> 
> This patch updates function mlx5_flow_validate_action_rss() with check of
> the input queue indices, as done in function
> mlx5_flow_validate_action_queue().
> 
> Fixes: 23c1d42c7138 ("net/mlx5: split flow validation to dedicated function")
