Change Description

  • Update lyrebird to latest (0.2.0)
  • Ripped out/migrated Webtunnel PT support in tor-expert-bundle
  • Update Webtunnel patch in tor-onion-proxy-library <- not sure if this is actually necessary in Alpha

How Tested

Making an aarch64 testbuild on tb-build-02, will verify once complete

@pierov @dan @clairehurst :

  • Please have a look this patch touches a lot of build stuff I'm not 100% familiar with. One Thing I'm not clear on is the role of tor-onion-proxy-library in alpha at the moment. It seems we have code in the patch-set which still refers to lyrebird as obfs4proxy (the exe to so rename logic) yet lyrebird is working fine for me in Alpha (both in legacy and beta bootstrapping)

@meskio @shelikhoo

  • Can you post a test webtunnel bridge-line (as an internal note if they are still somehow sekrit) ?
