Expected behavior

net:close() stops server

Actual behavior

net:close() results in "Lua error: stdin:1: illegal argument"

Test code

Wifi connected!
ftp_data = net.createServer(net.TCP, 30)
ftp_data:listen(21, function(s) print("listen") end)
ftp_data:close()

executed from console:
ftp_data = net.createServer(net.TCP, 30)

ftp_data:listen(21, function(s) print("listen") end)
ftp_data:close()
Lua error: stdin:1: illegal argument
stack traceback:
[C]: in method 'close'
stdin:1: in main chunk
[C]: in ?
[C]: in ?

I can confirm something is wonky. When I try this on my C3 I get Lua error: stdin:1: unknown error on the :close() call. Investigating...

Huh, LWIP's netconn_close() is returning arbitrary error codes now?!

@jmattsson

Okay, this is happening because the IDF/LWIP function lwip_netconn_do_close does not set a return code in this case, which means we just get random gibberish back as return code as that field is left uninitalised. Now the question is why, and why it's not actually closing the listening socket...

@sabanora If you have the ability to, you may want to check my branch which should have a solution for this: https://github.com/jmattsson/nodemcu-firmware/tree/dev-esp32-netconn-close-fix
