In order to send early data, we have to make sure no handshake has been initiated at all. To do that, we remove the CO_FL_SSL_WAIT_HS flag, so that we won't attempt to start a handshake. However, by removing those flags, we allow ssl_sock_to_buf() to call SSL_read(), as it's no longer aware that no handshake has been done, and SSL_read() will begin the handshake, thus preventing us from sending early data. The fix is to just call SSL_in_before() to check if no handshake has been done yet, in addition to checking CO_FL_SSL_WAIT_HS (both are needed, as CO_FL_SSL_WAIT_HS may come back in case of renegociation). In ssl_sock_from_buf(), fix the check to see if we may attempt to send early data. Use SSL_in_before() instead of SSL_is_init_finished(), as SSL_is_init_finished() will return 1 if the handshake has been started, but not terminated, and if the handshake has been started, we can no longer send early data. This fixes errors when attempting to send early data (as well as actually sending early data). This should be backported up to 2.8. |

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
- doc/internals for developer-specific documentation (not all up to date)
