Subject: [PATCH] ethdev: fix dev close in secondary process
Date: Fri, 27 May 2022 10:35:53 +0800 [thread overview]
Message-ID: <20220527023553.48177-1-humin29@huawei.com> (raw)
From: Min Hu <humin29@huawei.com>
Shared memory like port private resources should only be reserved
by primary process. Secondary process should not start dev, and
the state of 'dev_started' is only meaningful to primary process.
While secondary process need to close dev to release process private
resources.
This patch limited the scope of 'dev_started'.
Fixes: febc855b358e ("ethdev: forbid closing started device")
