These are configurable via consensus as well as via torrc - options PathBiasNoticeRate, PathBiasWarnRate, PathBiasExtremeRate. - The default values are 0.70, 0.50, and 0.30 respectively. - - Separate the log message levels from the decision to drop guards, - which also is available via torrc option PathBiasDropGuards. - PathBiasDropGuards defaults to 0 (off). - - Deprecate PathBiasDisableRate in favor of PathBiasDropGuards - in combination with PathBiasExtremeRate. - - Increase the default values for PathBiasScaleThreshold and - PathBiasCircThreshold from 200 and 20 to 300 and 150, respectively. - - Add in circuit usage accounting to path bias. If we try to use a - built circuit but fail for any reason, it counts as path bias. - Certain classes of circuits where the adversary gets to pick your - destination node are exempt from this accounting. Usage accounting - can be specifically disabled via consensus parameter or torrc. - - Convert all internal path bias state to double-precision floating - point, to avoid roundoff error and other issues. - - Only record path bias information for circuits that have completed - *two* hops. Assuming end-to-end tagging is the attack vector, this - makes us more resilient to ambient circuit failure without any - detection capability loss. |
