Hi,
When doing lwip close I get errno being set to EBADF.
This happens with the following callstack:
get_socket( "set_errno(EBADF);" )
event_callback() ("sock = get_socket(s);")
lwip_netconn_do_delconn ("API_EVENT(msg->conn, NETCONN_EVT_RCVPLUS, 0)")
<...>
Upon investigation I think this is because in the lwip_close scenario
netconn_prepare_delete is called twice.
First time is directly from lwip_close-> netconn_prepare_delete
Second time is via lwip_close-> free_socket-> free_socket_free_elements->
netconn_delete-> netconn_prepare_delete
The second time could be avoided if LWIP_NETCONN_FULLDUPLEX is set in which
case there is a test for it, but I see that is flag is in alpha state and if
not needed it is a bit strange to enable it just for this ?
But maybe I am misunderstanding something ?
Regards,
Bram
