Xiang Xiao 5fd8f78bf9 net/ipforward, tcp, and udp: Fix a chicken and egg problem by eliminating the check of the arp/neighbor tables before packet transmission
1. For buffered tcp/udp case, if CONFIG_NET_ARP_SEND/CONFIG_NET_ARP_IPIN/CONFIG_NET_ICMPv6_NEIGHBOR isn't enabled and the table doesn't contain ip<->ethaddr mapping yet, the logic will skip the realtransmission and then arp/neighbor can't steal the final buffer to generate arp/icmpv6 packet.
2.for all other case, the tcp layer or user program should already contain the retransmit logic, the check is redundancy and may generate many duplicated packets if arp/icmpv6 response is too slow because the cursor stop forward. If user still concern about the very first packet lost, he could fix the issue by enabling CONFIG_NET_ARP_SEND/CONFIG_NET_ICMPv6_NEIGHBOR at begin.

Kconfig net/tcp/Kconfig, include/nuttx/net/netconfig.h: Make RTO and WAIT_TIME configurable. This fix is not really correct: TCP RTO really should be calculated dynamically for each TCP connection: http://sgros.blogspot.com/2012/02/calculating-tcp-rto.html. 2019-08-26 11:03:27 -06:00

tcp_notifier.c net/tcp and udp: Fix errors in the new implementation of SO_LINGER. The tcp_drain() and udp_drain() functions were casting the working argument to the wrong type, resulting in hangs and abnormal behavior. There is a complexity in the tcp drain logic when the remote peer closes the socket before all Tx data has been flushed. Sometimes we are not notified of this case and wait the entire timeout unnecessarily. There is a workaround in place in tcp_txdrain(), but this really should be revisited. 2019-07-27 10:26:52 -06:00
tcp_recvwindow.c net/tcp/tcp_recvwindow.c: In order to receive data we must not only have IOBs available, but we must also have at least one IOB chain qentry available. Otherwise, we will advertise that we an buffer a lot of data when, in fact, we cannot. This is an expermental fix to a performance problem noted by Masayuki Ishikawa. 2018-09-22 09:33:29 -06:00
