The EVP_MD_CTX_create() and EVP_MD_CTX_destroy() functions were renamed to
EVP_MD_CTX_new() and EVP_MD_CTX_free() in OpenSSL 1.1.0, respectively. These
functions are used by the digest converter, introduced by the commit 8e36651ed
("MINOR: sample: Add digest and hmac converters"). So for prior versions of
openssl, macros are used to fallback on old functions.
This patch must only be backported if the commit 8e36651ed is backported too.
Use the refcount of the SSL_CTX' to free them instead of freeing them on
certains conditions. That way we can free the SSL_CTX everywhere its
pointer is used.
while working on issue #429, I encountered build failures with various
non-released openssl versions, let us improve ssl defines, switch to
features, not versions, for EVP_CTRL_AEAD_SET_IVLEN and
EVP_CTRL_AEAD_SET_TAG.
No backport is needed as there is no valid reason to build a stable haproxy
version against a development version of openssl.
SSL_CTX_set_ecdh_auto() is not defined when OpenSSL 1.1.1 is compiled
with the no-deprecated option. Remove existing, incomplete guards and
add a compatibility macro in openssl-compat.h, just as OpenSSL does:
bf4006a6f9/include/openssl/ssl.h (L1486)
This should be backported as far as 2.0 and probably even 1.9.
LIBRESSL_VERSION_NUMBER evaluates to 0 under OpenSSL, making the condition
always true. Check for the define before checking it.

Typically server line like:
'server-template srv 1-1000 *:443 ssl ca-file ca-certificates.crt'
load ca-certificates.crt 1000 times and stay duplicated in memory.
Same case for bind line: ca-file is loaded for each certificate.
Same 'ca-file' can be load one time only and stay deduplicated in
memory.
As a corollary, this will prevent file access for ca-file when
updating a certificate via CLI.
8c1cddef ("MINOR: ssl: new functions duplicate and free a ckch_store")
use some OpenSSL refcount functions that were introduced in OpenSSL
1.0.2 and OpenSSL 1.1.0.
Fix the problem by introducing them in openssl-compat.h.
Fix#336.
The following macros are now defined for openssl < 1.1 so that we
can remove the code performing direct access to the structures :
BIO_get_data(), BIO_set_data(), BIO_set_init(), BIO_meth_free(),
BIO_meth_new(), BIO_meth_set_gets(), BIO_meth_set_puts(),
BIO_meth_set_read(), BIO_meth_set_write(), BIO_meth_set_create(),
BIO_meth_set_ctrl(), BIO_meth_set_destroy()
It's always a pain to have to stuff lots of #ifdef USE_OPENSSL around
ssl headers, it even results in some of them appearing in a random order
and multiple times just to benefit form an existing ifdef block. Let's
make these headers safe for inclusion when USE_OPENSSL is not defined,
they now perform the test themselves and do nothing if USE_OPENSSL is
not defined. This allows to remove no less than 8 such ifdef blocks
and make include blocks more readable.
Since we're providing a compatibility layer for multiple OpenSSL
implementations and their derivatives, it is important that no C file
directly includes openssl headers but only passes via openssl-compat
instead. As a bonus this also gets rid of redundant complex rules for
inclusion of certain files (engines etc).
Some defines like OPENSSL_VERSION or X509_getm_notBefore() have nothing
to do in ssl_sock and must move to openssl-compat.h so that they are
consistently shared by the whole code. A warning in the code was added
against wild additions of macros there.
