Subject: [dpdk-dev] [PATCH 01/10] net/bnxt: handle flow create failure
Date: Mon, 13 Jan 2020 10:06:00 +0530 [thread overview]
Message-ID: <20200113043609.27363-2-kalesh-anakkur.purayil@broadcom.com> (raw)
In-Reply-To: <20200113043609.27363-1-kalesh-anakkur.purayil@broadcom.com>
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
If flow create fails due to not enough filter resources,
driver does not populate the rte_flow_error using
rte_flow_error_set().
Since "rte_errno" could have garbage value and is not relaiable,
it could cause a segfault in the stack in port_flow_complain().
Fix it to set rte_flow_error using rte_flow_error_set()
when flow create fails due to not enough filter resources.
