Subject: [dpdk-dev] [PATCH v2 02/12] net/bnxt: fix uninitialized ptr access in transmit handler
Date: Fri, 21 Sep 2018 21:55:49 -0700 [thread overview]
Message-ID: <20180922045559.27438-3-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20180922045559.27438-1-ajit.khaparde@broadcom.com>
From: Somnath Kotur <somnath.kotur@broadcom.com>
bnxt_start_xmit() was attempting to access an uninitialized ptr - txbd1
which would lead to segmentation fault.
Fix to initialize ptr to NULL and check for the same before access.
Fixes: f10258e39ec2 ("net/bnxt: fix HW Tx checksum offload check")
