First, OpenSSL is now initialized to be thread-safe. This is done by setting 2 callbacks. The first one is ssl_locking_function. It handles the locks and unlocks. The second one is ssl_id_function. It returns the current thread id. During the init step, we create as much as R/W locks as needed, ie the number returned by CRYPTO_num_locks function. Next, The reusable SSL session in the server context is now thread-local. Shctx is now also initialized if HAProxy is started with several threads. And finally, a global lock has been added to protect the LRU cache used to store generated certificates. The function ssl_sock_get_generated_cert is now deprecated because the retrieved certificate can be removed by another threads in same time. Instead, a new function has been added, ssl_sock_assign_generated_cert. It must be used to search a certificate in the cache and set it immediatly if found.
