When getting sockets from older process in sock_get_old_sockets(), we leverage getsockname() to fill sockaddr struct from known fd. However, the kernel doesn't know about our custom UNIX families such as CUST_ABNS and CUST_ABNSZ which are both based on AF_UNIX real family. Since haproxy socket API relies on effective family (and not real family) to recognize the socket type instead of having to guess it by analyzing the path content, let's restore it right after getsockname() since we have all the infos needed to deduce the right family. If the path starts with a NULL byte, we know that it is an abstract sock. Then we simply check <addrlen> value from getsockname() to know if the addr makes uses of the whole path space (normal ABNS) or partial path space (zero ABNS / aka ABNZ) terminated by 0. |

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)
