|
||
### 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 | ||
- Update to Rust 2018 edition (#396) | ||
- Migrate CI to Github Actions (#390) | ||
- Fix clippy lints, enforce clippy in CI (#395, #402, #403, #405, #407) | ||
- Use #[non_exhaustive] for enums and structs (#409, #411) | ||
- Simplify lifetime parameters of sockets, SocketSet, EthernetInterface (#410, #413) | ||
