It's regularly needed to call getsockopt() on a connection, but each time the calling code has to do all the job by itself. This commit adds a "get_opt()" callback on the protocol struct, that directly calls getsockopt() on the connection's FD. A generic implementation for standard sockets is provided, though QUIC would likely require a different approach, or maybe a mapping. Due to the overlap between IP/TCP/socket option values, it is necessary for the caller to indicate both the level and the option. An abstraction of the level could be done, but the caller would nonetheless have to know the optname, which is generally defined in the same include files. So for now we'll consider that this callback is only for very specific use. The levels and optnames are purposely passed as signed ints so that it is possible to further extend the API by using negative levels for internal namespaces. |

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
