Subject: [PATCH 9/9] raw/skeleton: fix segment fault when parse devargs
Date: Thu, 2 Mar 2023 07:48:25 +0000	[thread overview]
Message-ID: <20230302074825.31947-10-fengchengwen@huawei.com> (raw)
In-Reply-To: <20230302074825.31947-1-fengchengwen@huawei.com>

The rte_kvargs_process() was used to parse KV pairs, it also supports
to parse 'only keys' (e.g. socket_id) type. And the callback function
parameter 'value' is NULL when parsed 'only keys'.

This patch fixes segment fault when parse input args with 'only keys'
(e.g. self_test).

Fixes: 55ca1b0f2151 ("raw/skeleton: add test cases")
Cc: stable@dpdk.org
