Subject: [PATCH v2] net/idpf: fix crash when launching l3fwd
Date: Thu, 17 Nov 2022 10:15:09 +0000 [thread overview]
Message-ID: <20221117101509.14472-1-beilei.xing@intel.com> (raw)
In-Reply-To: <20221117100054.13836-1-beilei.xing@intel.com>
From: Beilei Xing <beilei.xing@intel.com>
There's core dump when launching l3fwd with 1 queue 1 core. It's
because NULL pointer is used if fail to configure device.
This patch removes incorrect check during device configuration,
and checks NULL pointer when executing VIRTCHNL2_OP_DEALLOC_VECTORS.
Fixes: 549343c25db8 ("net/idpf: support device initialization")
Fixes: 70675bcc3a57 ("net/idpf: support RSS")
Fixes: 37291a68fd78 ("net/idpf: support write back based on ITR expire")
