Subject: [PATCH v2 09/44] net/cnxk: fix segment fault when parse devargs
Date: Mon, 20 Mar 2023 09:20:35 +0000	[thread overview]
Message-ID: <20230320092110.37295-10-fengchengwen@huawei.com> (raw)
In-Reply-To: <20230320092110.37295-1-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'.

Fixes: 7eabd6c63773 ("net/cnxk: support inline security setup for cn9k")
Fixes: d25433c7a852 ("net/cnxk: add common devargs parsing")
Fixes: df5cf15faaa9 ("net/cnxk: support IPsec rule reservation scheme")
Fixes: 7eabd6c63773 ("net/cnxk: support inline security setup for cn9k")
Fixes: c91d30f46d4c ("net/cnxk: support configuring channel mask via devargs")
