Version 0.3.6

on GitHub

Added

• Yggdrasil now has a public API with interfaces such as yggdrasil.ConnDialer, yggdrasil.ConnListener and yggdrasil.Conn for using Yggdrasil as a transport directly within applications
• Session gatekeeper functions, part of the API, which can be used to control whether to allow or reject incoming or outgoing sessions dynamically (compared to the previous fixed whitelist/blacklist approach)
• Support for logging to files or syslog (where supported)
• Platform defaults now include the ability to set sane defaults for multicast interfaces

Changed

• Following a massive refactoring exercise, Yggdrasil's codebase has now been broken out into modules
• Core node functionality in the yggdrasil package with a public API
  • This allows Yggdrasil to be integrated directly into other applications and used as a transport
  • IP-specific code has now been moved out of the core yggdrasil package, making Yggdrasil effectively protocol-agnostic
• Multicast peer discovery functionality is now in the multicast package
• Admin socket functionality is now in the admin package and uses the Yggdrasil public API
• TUN/TAP, ICMPv6 and all IP-specific functionality is now in the tuntap package
• PPROF debug output is now sent to stderr instead of stdout
• Node IPv6 addresses on macOS are now configured as secured
• Upstream dependency references have been updated, which includes a number of fixes in the Water library

Fixed

• Multicast discovery is no longer disabled if the nominated interfaces aren't available on the system yet, e.g. during boot
• Multicast interfaces are now re-evaluated more frequently so that Yggdrasil doesn't need to be restarted to use interfaces that have become available since startup
• Admin socket error cases are now handled better
• Various fixes in the TUN/TAP module, particularly surrounding Windows platform support
• Invalid keys will now cause the node to fail to start, rather than starting but silently not working as before
• Session MTUs are now always calculated correctly, in some cases they were incorrectly defaulting to 1280 before
• Multiple searches now don't take place for a single connection
• Concurrency bugs fixed
• Fixed a number of bugs in the ICMPv6 neighbor solicitation in the TUN/TAP code
• A case where peers weren't always added correctly if one or more peers were unreachable has been fixed
• Searches which include the local node are now handled correctly
• Lots of small bug tweaks and clean-ups throughout the codebase
