Subject: [dpdk-stable] [PATCH v1] eal: fix random device arguments in device iterator
Date: Wed, 27 Oct 2021 16:22:21 +0800 [thread overview]
Message-ID: <20211027082221.693957-1-xuemingl@nvidia.com> (raw)
Devargs used in device iterator initialization wasn't set to zero, random
data like bus string lead to invalid address access.
This patch initializes devargs.
Fixes: c99a2d4c6b7f ("eal: implement device iteration initialization")
