Subject: Bitrot: auto-initialization of OpenSSL 1.1.0
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=914001539c158933cbfe0cf6d270b1370b6f804a;p=thirdparty%2Fpostfix.git

Bitrot: auto-initialization of OpenSSL 1.1.0

The functions SSL_library_init(), SSL_load_error_strings() and
OpenSSL_add_ssl_algorithms() are deprecated in OpenSSL 1.1.0.

Instead the library auto-initializes.  Though it is possible to
call OPENSSL_init_crypto() and OPENSSL_init_ssl() for explicit
control over initialization, for now there is no apparent reason
to do so.  This may change, so explicit initialization might yet
become necessary.
