This project is not part of the GNU Project.

lwIP is a small independent implementation of the TCP/IP protocol suite that has been initially developed by Adam Dunkels and is now continued here.

The focus of the lwIP TCP/IP implementation is to reduce resource usage while still having a full scale TCP. This makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM.

Main features include:
- Protocols: IP, IPv6, ICMP, ND, MLD, UDP, TCP, IGMP, ARP, PPPoS, PPPoE
- DHCP client, DNS client (incl. mDNS hostname resolver), AutoIP/APIPA (Zeroconf), SNMP agent (v1, v2c, v3, private MIB support & MIB compiler)
- APIs: specialized APIs for enhanced performance, optional Berkeley-alike socket API
- Extended features: IP forwarding over multiple network interfaces, TCP congestion control, RTT estimation and fast recovery/fast retransmit
- Addon applications: HTTP(S) server, SNTP client, SMTP(S) client, ping, NetBIOS nameserver, mDNS responder, MQTT client, TFTP server

Contrib code has been moved to the main repository, subdir 'contrib'.

lwIP 2.1.2 released
     posted by goldsimon, Thu 22 Nov 2018 08:10:20 PM UTC - 0 replies

lwIP 2.1.2 is now available from the lwIP download area
or via git (using the STABLE-2_1_2_RELEASE tag).

This is an even smaller bugfix-only release fixing 4 bugs (see CHANGELOG). However, 2 of them are in the core TCP code, so all users of 2.1.0 or 2.1.1 are strongly suggested to upgrade!

Contrib has still not been changed since 2.1.0.

Thanks for all contributions!

lwIP 2.1.1 released
     posted by goldsimon, Thu 08 Nov 2018 09:34:54 PM UTC - 0 replies

lwIP 2.1.1 is now available from the lwIP download area
or via git (using the STABLE-2_1_1_RELEASE tag).

This is a smaller bugfix-only release. Contrib has not been changed since 2.1.0.
For a list of the 11 bugs fixed, see CHANGELOG.

Please note that all users of 2.1.0 should upgrade (should be a matter of copying the new files only, no changes required).

Thanks for all contributions!

lwIP 2.1.0 is now available from the lwIP download area on savannah [1] or via git (using the STABLE-2_1_0_RELEASE tags in both repositories).

The feature I want to point out most for this release is TLS support via the new altcp API (see [2]). ...
