Subject: [dpdk-stable] [PATCH] net/ring: fix unchecked return value
Date: Tue, 22 Sep 2020 18:20:15 +0100
Message-ID: <20200922172015.266698-1-kevin.laatz@intel.com> (raw)

Add a check for the return value of the sscanf call in
parse_internal_args(), returning an error if we don't get the expected
result.

Coverity issue: 362049
Fixes: 96cb19521147 ("net/ring: use EAL APIs in PMD specific API")
Cc: stable@dpdk.org
