#32696: Recommend supported protocol versions based on 0.3.5.7 -------------------------+------------------------------------------------- Reporter: teor | Owner: (none) Type: task | Status: new Priority: Medium | Milestone: Tor: 0.4.3.x-final Component: Core | Version: Tor/Tor | Keywords: 043-can, auth-deploy-Feb-2020, Severity: Normal | teor-backlog Actual Points: 0.1 | Parent ID: Points: 0.5 | Reviewer: Sponsor: | -------------------------+------------------------------------------------- According to proposal 303, we recommend some protocol versions every time an LTS release is no longer supported: https://gitweb.torproject.org/torspec.git/tree/proposals/303-protover- removal-policy.txt#n18
0.2.9.8 supported these protocol versions: https://gitweb.torproject.org/tor.git/tree/src/or/protover.c?h=tor-0.2.9.8#n283 When 0.2.9 is no longer supported, the earliest stable LTS will be 0.3.5.7, which supports these protocol versions: https://gitweb.torproject.org/tor.git/tree/src/core/or/protover.c?h=tor-0.3.5.7#n379 Therefore, we should recommend these protocol versions for clients and relays: Cons=2 Desc=2 DirCache=2 * HSDir=2 * HSIntro=4 * HSRend=2 Link=5 * LinkAuth=3 * Microdesc=2 Relay=2 The starred protovers are not supported by 0.2.9, so it will warn on bootstrap / consensus download. We can make that change in master here: https://gitweb.torproject.org/tor.git/tree/src/feature/dirauth/dirvote.c#n4630 The required protocols must stay the same, I'll open another ticket for them. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/32696> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
