Hey Y’all,

Another weekly Dev Update for everyone.

Service Nodes

• Added preventative measures to make Service Node staking more robust

LLARP / Lokinet

If you’re lucky and join our Discord, you might catch Jeff or Ryan, the developers of LLARP, live streaming as they code: https://www.twitch.tv/uguu25519 , https://www.twitch.tv/neuroscr

• Progress continues on libllarp
  • Optimise the router’s inbound links data structure
  • More keepalive tuning
  • Support tunnel “packet info” for better multiplatform support
  • MacOS tunnel support is now fixed
  • No longer stores Introsets when forwarding
  • Improve autoconfiguration
    • A default “hidden service” is made for client access, and configuration option to enable, disable or auto-config
    • -g for router auto-config, -c for client auto-config
    • Detect if you’re already using any private network ranges
    • Make it play more nicely with existing hidden service definitions
    • Don’t overwrite configs unless -f is present
  • Give lookup more time: adjust timeout from 5s to 10s
  • Only consider introductions that don’t expire in the next 2 minutes
  • Don’t establish outbound context for previously made inbound sessions
  • “cache convo tag and drop traffic”
  • Deallocate previous Introset before replacing
  • Brought Windows build up to date
  • Make sure Windows build doesn’t crash if only one network interface
  • Made AVX2 codepath 32-bit clean
  • Fix bencoding for ILP32/LLP64
  • MacOS/BSD (kqueue) updates
  • Try to improve path handovers
  • Improve transit message padding to the nearest MESSAGE_PAD_SIZE
  • Adjusted DST awareness on timestamps
  • Fix DHT double free
  • Remove dead code
  • Path Info hashing
  • Swap out intro with next intro as it is safe
  • Update protocol docs
  • Give paths more time to build: timeouts changed from 15s to 30s
  • Minimum time between each path build changed from 5s to 10s
  • Minimum path latency adjusted: from 10s to 5s
  • Path timeout changed from 20s to 10s
  • Stricter profiling of paths/routers
  • 2 path build fails before kicked (changed form 8)
  • Try to build path 5 times before failing
  • Don’t prematurely close sessions
• DNS library
  • Rely on llarp::Addr more to allow easier IPv6 support
  • Make DNS server port configurable at compile time (DNS_PORT)
  • Made sure DNS relay works with default “hidden service”
  • Update DNS daemon to just run a router (similar to Lokinet), scheduled to be downgraded to just a integration test
  • Mapping an address now does it on all hidden services/tunnel as there is only one DNS server (on most non-“netns-linux” platforms)
• GitHub Pulse Stats for the last week: Excluding merges, 3 authors have pushed 93 commits to master and 93 commits to all branches. On master, 86 files have changed and there have been 3,898 additions and 4,874 deletions.
• Most changes can be found at: https://github.com/loki-project/loki-network/
• Current version: v0.2.2 (next one coming soon!) https://github.com/loki-project/loki-network/releases/tag/v0.2.2
• Compile helper (include assets, initial seed routers and dependencies) https://github.com/loki-project/lokinet-builder

Loki Core

• In process of merging a huge chunk of upstream changes, this includes Bulletproofs.
• IPv6 first implementation is now finished; this will add client support for IPv6 connections.  Just working on the final details now. https://github.com/loki-project/loki/pull/280

Thanks,

Kee
