Description

After we put a limit on the number of testing circuits (#28511), we can open NUM_PARALLEL_TESTING_CIRCS*3/2 circuits when we start testing bandwidth. Otherwise, circuits can time out and be replaced with new circuits, leading to a DoS.

Milestone: Tor: 0.4.0.x-finalTor: unspecified

We might remove bandwidth self-tests.

comment:2 Changed 10 months ago by teor

These open, non-merge_ready tickets can not get backported to 0.3.3, because 0.3.3 is now unsupported.

comment:3 Changed 10 months ago by teor

Keywords: 033-backport-unreached added

Hmm, I guess they should still get 033-backport-unreached

Keywords: needs-proposal added

These tickets need a proposal before we write any code.

The two competing proposals in #22453 are:

  1. Remove the bandwidth self-test
  2. Increase the bandwidth self-test so it measures a reasonable amount of bandwidth

0.3.4 is unsupported, we won't be backporting anything else to it.
