Subject: [dpdk-dev] [PATCH 2/2] net/cxgbe: skip parsing match items with no spec
Date: Sat, 15 Dec 2018 00:31:54 +0530	[thread overview]
Message-ID: <361cf24699f7976d5b03fa5833ce19db7237bfd3.1544813681.git.rahul.lakkireddy@chelsio.com> (raw)
In-Reply-To: <cover.1544813681.git.rahul.lakkireddy@chelsio.com>
In-Reply-To: <cover.1544813681.git.rahul.lakkireddy@chelsio.com>

Skip parsing pattern match items that have no spec. This fixes NULL
dereference when accessing their non-existent spec.

Fixes: ee61f5113b17 ("net/cxgbe: parse and validate flows")
Cc: stable@dpdk.org
