o Major bugfixes (congestion control):
|
|
- Implement RFC3742 Limited Slow Start. Congestion control was
|
|
overshooting the congestion window during slow start, particularly for
|
|
onion service activity. With this fix, we now update the congestion
|
|
window more often during slow start, as well as dampen the exponential
|
|
growth when the congestion window grows above a capping parameter.
|
|
This should reduce the memory increases guard relays were seeing, as
|
|
well as allow us to set lower queue limits to defend against
|
|
ongoing DoS attacks. Fixes bug 40642; bugfix on 0.4.7.5-alpha.
