Subject: [PATCH 2/9] compressdev: fix segment fault when parse input args
Date: Thu, 2 Mar 2023 07:48:18 +0000 [thread overview]
Message-ID: <20230302074825.31947-3-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. socket_id).
Fixes: ed7dd94f7f66 ("compressdev: add basic device management")
