Subject: [dpdk-stable] [PATCH] raw/ioat: fix memory leak in device configure
Date: Thu, 17 Jun 2021 14:17:52 +0000
Message-ID: <20210617141752.93312-1-kevin.laatz@intel.com> (raw)

During device configure, memory is allocated for "hdl_ring_flags". In the
event of another call to the device configure function (reconfigure), a
memory leak would occur. This patch fixes the memory leak by free'ing the
memory before reallocating it.

Fixes: 245efe544d8e ("raw/ioat: report status of completed jobs")
