This patch fixes two wrong calls to bbr_inflight(). bbr_target_inflight() aim is to compute the number of bytes BBR has to put on the network as bytes in flight (sent but not acked bytes). It must call bbr_inflight() with the current window gain value (in place of a wrong fixed 100 gain value here, in percents). bbr_is_time_to_cruise() also called bbr_inflight() with a wrong gain value as parameter due to a confusion between the value mentioned by the RFC (1 meaning 100% of the current window) and our implementation which needs value in percents (so 100 in place of 1 here). Note that bbr_is_time_to_cruise() aim is to make BBR the decision to leave the probing_bw down state. The bug had as side effect to make BBR stay in this state during too long periods of time during which the bottleneck bandwidth is decreasing, leading to big oscillations between the mininum and maximum bottleneck bandwidth estimations. This patch must be backported to 3.1 where BBR was first implemented. |

HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
Please refer to the following files depending on what you're looking for:
- INSTALL for instructions on how to build and install HAProxy
- BRANCHES to understand the project's life cycle and what version to use
- LICENSE for the project's license
- CONTRIBUTING for the process to follow to submit contributions
The more detailed documentation is located into the doc/ directory:
- doc/intro.txt for a quick introduction on HAProxy
- doc/configuration.txt for the configuration's reference manual
- doc/lua.txt for the Lua's reference manual
- doc/SPOE.txt for how to use the SPOE engine
- doc/network-namespaces.txt for how to use network namespaces under Linux
- doc/management.txt for the management guide
- doc/regression-testing.txt for how to use the regression testing suite
- doc/peers.txt for the peers protocol reference
- doc/coding-style.txt for how to adopt HAProxy's coding style
