  • Remove IpRepr::Unspecified (#579)

New features

  • tcp: Allow distinguishing between graceful (FIN) and ungraceful (RST) close. On graceful close, recv() now returns Error::Finished. On ungraceful close, Error::Illegal is returned, as before. (351)
  • sockets: Add support for attaching async/await Wakers to sockets. Wakers are woken on socket state changes. (394)
  • tcp: Set retransmission timeout based on an RTT estimation, instead of the previously fixed 100ms. This improves performance on high-latency links, such as mobile networks. (406)
  • tcp: add Delayed ACK support. On by default, with a 10ms delay. (404)
  • ip: Process broadcast packets directed to the subnet's broadcast address, such as 192.168.1.255. Previously broadcast packets were only processed when directed to the 255.255.255.255 address. (377)

Fixes

  • udp,raw,icmp: Fix packet buffer panic caused by large payload (332)
  • dhcpv4: use offered ip in requested ip option (310)
  • dhcpv4: Re-export dhcp::clientv4::Config
  • dhcpv4: Enable proto-dhcpv4 feature by default. (327)
  • ethernet,arp: Allow for ARP retry during egress (368)
  • ethernet,arp: Only limit the neighbor cache rate after sending a request packet (369)
  • tcp: use provided ip for TcpSocket::connect instead of 0.0.0.0 (329)
  • tcp: Accept data packets in FIN_WAIT_2 state. (350)
  • tcp: Always send updated ack number in ack_reply(). (353)
  • tcp: allow sending ACKs in FinWait2 state. (388)
  • tcp: fix racey simultaneous close not sending FIN. (398)
  • tcp: Do not send window updates in states that shouldn't do so (360)
  • tcp: Return RST to unexpected ACK in SYN-SENT state. (367)
  • tcp: Take MTU into account during TcpSocket dispatch. (384)
  • tcp: don't send data outside the remote window (387)
  • phy: Take Ethernet header into account for MTU of RawSocket and TapInterface. (393)
  • phy: add null terminator to c-string passed to libc API (372)

Quality of Life™ improvements
