Except block signature verification failure, is there any other usual peer disconnection scenario?
@abn2357 There are many scenarios where the connection with the peer will be disconnected, such as: handshake failure, data acquisition timeout, receiving messages sent by the peer that do not conform to the protocol, etc.
Are there any other disconnect scenarios that have an ambiguous reason code?
Software Versions
Expected behaviour
When disconnected, the exact reason for the disconnection can be obtained through the disconnection message.
Actual behaviour
When running Java-tron, I found that if I wanted to disconnect a peer in certain scenarios, the disconnect message sent carried an ambiguous reason code. You can take a look at the example below.
Example: The node receives the block sent by the peer and then disconnects the peer due to block signature verification failure, but the reason for the disconnection message being sent is UNKNOWN.
Therefore, after receiving the disconnection message, the peer cannot accurately know the specific reason for being disconnected. I think the reason code carried in the disconnect message in this example can be clearer. In addition, do you think it is necessary to check whether there are other disconnection scenarios with similar problems?
Frequency
It occurs every time in the above scenarios.
Steps to reproduce the behaviour
Send a block with an invalid signature to the node.
