Subject: [PATCH] devargs: Fix crash due to global devargs uninitailization from secondary process
Date: Mon, 14 Feb 2022 22:38:11 +0530 [thread overview]
Message-ID: <20220214170811.1192-1-madhuker.mythri@oracle.com> (raw)
From: Madhuker Mythri <madhuker.mythri@oracle.com>
Failsafe pmd started crashing with global devargs syntax as devargs is
not memset to zero. Access it to in rte_devargs_parse() resulted in a
crash when called from secondary process.
Bugzilla Id: 933
