Subject: [RFC 03/13] cifs: Fix oops due to uncleared server->smbd_conn in reconnect
Date: Wed, 25 Jan 2023 21:45:33 +0000 [thread overview]
Message-ID: <20230125214543.2337639-4-dhowells@redhat.com> (raw)
In-Reply-To: <20230125214543.2337639-1-dhowells@redhat.com>
In smbd_destroy(), clear the server->smbd_conn pointer after freeing the
smbd_connection struct that it points to so that reconnection doesn't get
confused.
Fixes: 8ef130f9ec27 ("CIFS: SMBD: Implement function to destroy a SMB Direct connection")
