Subject: [PATCH] net/failsafe: Fix crash due to global devargs syntax parsing from secondary process
Date: Thu, 10 Feb 2022 12:40:52 +0530	[thread overview]
Message-ID: <20220210071052.527-1-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
