I confirm that this issue still happens.
- I run server on the first PC (Windows)
- I run the client 1 on a Macbook, and I repeatly start & stop the client 1.
- I run the client 2 on a Mac Mini and the connection to server is delayed. Sometimes, client cannot connect to server:
client started on port 52916
client id is 116b51e88fa7df47
client connecting to server 192.168.137.1:40000 [1/1]
client connect failed. connection request timed out
client disconnected

I'm going to extend the logs, and try to repro over here
from netcode.

Following this logic, I think I know what it is:
if ( error == WSAEWOULDBLOCK || error == WSAECONNRESET )
return 0;
The WSACONNRESET is stopping packets from being received, and it's windows specific... should be able to fix, then you can verify.

Thanks for your advice. I have checked the test case and the issue has gone.

Can still you reproduce this connection delay if you run a client on a different machine than the one doing the non-cleanup clients?
from netcode.

Secondly, is your client.c still binding to port 0, eg. random client port number?

- I run the client on a different machine (MacOS) and connect to server (Windows) and the problem's still there.
- Yes, I used the modified version of https://github.com/networkprotocol/netcode/blob/master/client.c by commenting line 97
signal( SIGINT, interrupt_handler );. The configuration of port is 0 and after starting client, the port will be generated randomly
from netcode.

This result is very strange. Are the WASECONNRESET errors showing up on the clients or on the server?
from netcode.

Also, I mean can you reproduce the connection delay with clients running on one machine, and then connect a client from a second machine, to a server running on a third machine? (Sorry to be a pain!) I just want to be 100% sure this is something specific to the server, and not a direct consequence of the socket layer on the clients not having the socket cleaned up.

OK. I will look into this. Can you please post logs from the clients that connect properly, the client that has the connection delay, the client that fails to connect, and the server -- all with netcode_log_level set to NETCODE_LOG_LEVEL_DEBUG
thanks!
from netcode.

Hi, I'm trying to match the client logs with the server logs in the delay case.
In the client logs, I see various port numbers.
Then I look at the server logs, and I see different port numbers.
Are you certain that the server log corresponds to the complete server log in the delay case?
Here are the logs I'm working from:

@gafferongames I think you are working on the "client log of failure case" with "server log of delay case". They are not on the same case.

Confirmed. Cross checking port numbers now and it seems to line up.

Does this only happen when the server is running on windows, because I'm on Mac and I cannot repro it even though I have adjusted the client.c to remove the signal handler.

Yes, it does only on Windows

commented on June 16, 2024
The good news is that since it is Windows specific, we can know that the issue is something in the socket receive processing, or the OS support for sockets. The logic is fine -- all logic is shared across all platforms.

OK, I believe I have a fix checked in now. Let me know how it goes. The issue is windows specific.
from netcode.
gafferongames
commented on June 16, 2024
The fix + explanation of what was going on:
int result = recvfrom( socket->handle, (char*) packet_data, max_packet_size, 0, (struct sockaddr*) &sockaddr_from, &from_length );
#if NETCODE_PLATFORM == NETCODE_PLATFORM_WINDOWS
if ( result == SOCKET_ERROR )
{
int error = WSAGetLastError();
if ( error == WSAEWOULDBLOCK )
return 0;
/*
IMPORTANT: This happens on windows because a previous sendto on this socket went to an address + port
belonging to a socket that was shut down forcefully (eg. OS closed the socket).
You can trigger this behavior by commenting out the client signal handler in client.c and then
repeatedly connecting to the server.
What happens is that we get the ICMP port unreacable message back, and that triggers the WSACONNRESET
on the next recvfrom. This behavior is windows specific.
If we just return 0, we will stop receiving packets for this frame, and this will streeeeeetch out packets
and cause problems where clients can't connect or receive packets because each time we see the WSACONNRESET we
stop processing packets for that frame.
The solution is to just ignore the WSACONNRESET error, and call recvfrom again...
*/
if ( error == WSAECONNRESET )
{
return netcode_socket_receive_packet( socket, from, packet_data, max_packet_size );
}
netcode_printf( NETCODE_LOG_LEVEL_ERROR, "error: recvfrom failed with error %d\n", error );
return 0;
}
#else // #if NETCODE_PLATFORM == NETCODE_PLATFORM_WINDOWS
from netcode.
kienhg96
commented on June 16, 2024
I think the solution would resolve the issue. However, I have a question.
If in the previous frame, client does some sendtos, will recvfrom produce a lot of WSAECONNRESETs continously and lead netcode_socket_receive_packet to recusive calling very deeply and, maybe, stack overflow?
from netcode.
gafferongames
commented on June 16, 2024
Yes, the recursion is a bit gross, BUT, there is only one WSAECONNRESET per-packet sent from the server, so I think the recursion won't go on forever, it will be reasonable. Let me know if you see stack issues around the recursion, and if so we can refactor the socket receive function to iterate over recvfrom and ignore WSAECONNRESET until it gets a correct result.

The only thing I worry about is DDoS spoofing ICMP packets. I would recommend that in production, you block ICMP to your servers.
