I really like the 4 over 6 thing ---------- Forwarded message --------- From: Juliusz Chroboczek <j...@irif.fr> Date: Thu, May 5, 2022 at 5:06 AM Subject: [Babel-users] ANNOUNCE: babeld-1.12 To: <babel-us...@lists.alioth.debian.org>
Dear all, Babeld 1.12 is available from https://www.irif.fr/~jch/software/files/babeld-1.12.tar.gz https://www.irif.fr/~jch/software/files/babeld-1.12.tar.gz.asc For more information about the Babel routing protocol, please see https://www.irif.fr/~jch/software/babel/ This version implements v4-via-v6 routing, which allows an IPv6-only router to route IPv4 completely transparently. The work is due to Théophile Bastian, Toke Høyland-Jørgensen, and myself. The protocol is described in RFC 9229, which has not been published yet; in the meantime, you may find the final draft at https://datatracker.ietf.org/doc/html/draft-ietf-babel-v4viav6-08 V4-via-v6 is enabled by default on Linux kernel 5.13 and later, which may cause issues in your network: - IPv6-only routers will suddently start routing IPv4; if you rely on IPv6-only routers to isolate you from the IPv4 Internet, this will no longer work. Please set up filtering rules and firewalls if you wish to be isolated from the Internet. - IPv6-only routers will suddenly start sending ICMPv4 messages using the IPv4 "dummy address" 192.0.0.8; please make sure your firewall rules let through ICMPv4 packets with source equal to 192.0.0.8 lest you suffer from PMTUD blackholes. (This applies even if you're not running Babel itself: filtering ICMPv4 packet-too-big is almost always a mistake.) The full changelog follows. 5 May 2022: babeld-1.12 * Implement v4-via-v6 routing (RFC 9229), which allows a router with IPv4 addresses only to route IPv4. Thanks to Théophile Bastian. * Enable extended Netlink acks when available. Thanks to Toke Høyland-Jørgensen. * Fix restoring of interface configuration to avoid unbounded memory consumption. Thanks to andrew-hoff. * Fix handling of deny filters in the install chain. -- Juliusz _______________________________________________ Babel-users mailing list babel-us...@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/babel-users -- FQ World Domination pending: https://blog.cerowrt.org/post/state_of_fq_codel/ Dave Täht CEO, TekLibre, LLC _______________________________________________ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel
