v0.4.0

New release v0.4.0

• Added dispatcher SHIM
• Added proper support for dispatched_ports port range in topology files
• Added bootstrapping through reverse lookup to determine local DNS search domain
• Removed deprecated ScmpChannel

For a full history of changes please see the CHANGELOG.

What's Changed

BREAKING CHANGE

• The SHIM now occupies port 30041. This means any application trying to use that port will fail.
  • Solution #1: Just use any other port instead, the SHIM will forward traffic to it.
  • Solution #2: Disable the SHIM with org.scion.shim = false or SCION_SHIM = false.

Added

• Add a SHIM, required for #130 (topo file port range support). #131
• ManagedThread test helper. #136
• Support for dispatched_ports in topo files. Deprecated configureRemoteDispatcher(). #130
• Bootstrapping: use reverse domain lookup to find NAPTR records. #138

Changed

• Buildified PingPong test helper. #132
• Server to use BR addresses instead of received addresses. #133
• MockNetwork should use topofiles. #134
• MockNetwork should really use topofiles. #135

Fixed

• Do not start SHIM if dispatcher port range is ALL. #139
• Cleanup and fixed SHIM tests and other tests. #140

Removed

• Removed deprecated code, e.g. ScmpChannel and public ScionAddress. #141

Full Changelog: v0.2.0...v0.3.0

v0.2.0

New release with API changes

Despite being a minor release, this release changes (and partially breaks) existing API.
Breaking changes include:

• ScionService.getPaths(...) returns List<Path> instead of List<RequestPath>. The classes RequestPath and ResponsePath will be removed from the public in a future release. Please just use Path instead.
• Path metadata has been moved to a separate class. Instead of path.getMtu(), please use path.getMetadata().getMtu().
• (Scion)DatagramChannel.receive() now returns a ScionSocketAddress (which contains a path).
• (Scion)DatagramChannel.send() now returns int instead of a path. This improves compatibility with the JDK DatagramChannel.
• DatagramChannel has been renamed to ScionDatagramChannel and DatagramSocket has been renamed to ScionDatagramSocket. The old classes still exist for backwards compatibility but will be removed in future.

Overview

• Numerous API changes. Most changes are backward compatible (via deprecated API) but some are breaking changes, see above.
• Improved SCMP handling and features
• Some bug fixes and general clean up
