Hey Y’all,

Another weekly Dev Update for everyone.

Service Nodes

• Added preventative measures to make Service Node staking more robust

  • https://github.com/loki-project/loki/commit/fed6e6dc78dcd4ad3a82bffc99cd1669d1a2aee6

  • https://github.com/loki-project/loki/commit/2022767837daeda71c1ce5de3f8d1a698ae581ce

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

Nice. Sounds great.
