Subject: [PATCH 5.4 053/122] vsock: notify server to shutdown when client has pending signal
Date: Thu, 15 Jul 2021 20:38:20 +0200 [thread overview]
Message-ID: <20210715182503.180492990@linuxfoundation.org> (raw)
In-Reply-To: <20210715182448.393443551@linuxfoundation.org>
From: Longpeng(Mike) <longpeng2@huawei.com>
[ Upstream commit c7ff9cff70601ea19245d997bb977344663434c7 ]
The client's sk_state will be set to TCP_ESTABLISHED if the server
replay the client's connect request.
However, if the client has pending signal, its sk_state will be set
to TCP_CLOSE without notify the server, so the server will hold the
corrupt connection.
client server
1. sk_state=TCP_SYN_SENT |
2. call ->connect() |
3. wait reply |
| 4. sk_state=TCP_ESTABLISHED
| 5. insert to connected list
| 6. reply to the client
7. sk_state=TCP_ESTABLISHED |
8. insert to connected list |
9. *signal pending* <--------------------- the user kill client
10. sk_state=TCP_CLOSE |
client is exiting... |
11. call ->release() |
virtio_transport_close
if (!(sk->sk_state == TCP_ESTABLISHED ||
sk->sk_state == TCP_CLOSING))
return true; *return at here, the server cannot notice the connection is corrupt*
So the client should notify the peer in this case.
