[lwip-devel] [bug #16830] err_tcp() posts to connection mailbox when no pend on the mailbox is active

[Frédéric Bernon]

Follow-up Comment #10, bug #16830 (project lwip):

The "if (msg_copy.conn->err != ERR_OK) {"  in api_msg_input is not a so good
idea, because even with an error on "conn->err", you have to execute
do_disconnect, do_close & do_delconn. We can move the check at the beginning
of do_listen, do_send, do_recv, do_write & do_join_leave_group...
