OpenSSL 4.0 is deprecating X509_STORE_get0_objects(). Every occurence of X509_STORE_get0_objects() was first replaced by X509_STORE_get1_objects(). This changes the ref count of the STACK_OF(X509_OBJECT) everywhere, and need it to be sk_X509_OBJECT_pop_free(objs, X509_OBJECT_free) each time. X509_STORE_get1_objects() is not available in AWS-LC, OpenSSL < 3.2, LibreSSL and WolfSSL, so we need to still be compatible with get0. To achieve this, 2 macros were added X509_STORE_getX_objects() and sk_X509_OBJECT_popX_free(), these macros will use either the get0 or the get1 macro depending on their availability. In the case of get0, sk_X509_OBJECT_popX_free() will just do nothing instead of trying to free. Don't backport that unless really needed if we want to be compatible with OpenSSL 4.0. It changes all the refcounts. |

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.

- 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
