From: Michael Baum Date: Thu, 3 Sep 2020 10:13:32 +0000 (+0000) Subject: net/mlx5: fix Rx hash queue creation error flow X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=93fa67fb119147e0219351fd1cbc54645e15dcab;p=dpdk.git net/mlx5: fix Rx hash queue creation error flow The mlx5_hrxq_new function allocates several resources and if one of the allocations fails, the function jumps to an error label where it releases all the allocated resources. When the TIR action creation fails, the hrxq memory is not released what can cause a resource leak. Add an appropriate release to the hrxq pointer in the error flow.
