2023-01-10Avoid increasing the congestion window if it is not full.Mike Perry
Also provides some stickiness, so that once full, the congestion window is considered still full for the rest of an update cycle, or the entire congestion window. In this way, we avoid increasing the congestion window if it is not fully utilized, but we can still back off in this case. This substantially reduces queue use in Shadow.

2022-11-29dirauth: rotate moria1 keys and portsRoger Dingledine
Rotate the relay identity key and v3 identity key for moria1. They have been online for more than a decade, there was a known potential compromise, and anyway refreshing keys periodically is good practice. Advertise new ports too, to avoid confusion. Closes ticket 40722.
2022-11-28dns: Make TTLs fuzzy at exit relaysRasmus Dahlberg
This change mitigates DNS-based website oracles by making the time that a domain name is cached uncertain (+- 4 minutes of what's measurable). Resolves TROVE-2021-009. Fixes #40674
2022-11-28Clip DNS TTL values once in event callbackRasmus Dahlberg
This change ensures that other parts of the code base always operate on the same clipped TTL values, notably without being aware of clipping.
2022-11-23relay: Use the configured number of threads for worker work calculationDavid Goulet
We cap our number of CPU worker threads to at least 2 even if we have a single core. But also, before we used to always add one extra thread regardless of the number of core. This meant that we were off when re-using the get_num_cpus() function when calculating our onionskin work overhead because we were always off by one. This commit makes it that we always use the number of thread our actual thread pool was configured with. Fixes #40719 Signed-off-by: David Goulet <dgoulet@torproject.org>

2022-11-09relay: Make the max pending tasks per CPU a consensus parameterDavid Goulet
