Migrate to OpenSSL 3.0 in advance of FreeBSD 14.0. OpenSSL 1.1.1 (the version we were previously using) will be EOL as of 2023-09-11. Most of the base system has already been updated for a seamless switch to OpenSSL 3.0. For many components we've added `-DOPENSSL_API_COMPAT=0x10100000L` to CFLAGS to specify the API version, which avoids deprecation warnings from OpenSSL 3.0. Changes have also been made to avoid OpenSSL APIs that were already deprecated in OpenSSL 1.1.1. The process of updating to contemporary APIs can continue after this merge. Additional changes are still required for libarchive and Kerberos- related libraries or tools; workarounds will immediately follow this commit. Fixes are in progress in the upstream projects and will be incorporated when those are next updated. There are some performance regressions in benchmarks (certain tests in `openssl speed`) and in some OpenSSL consumers in ports (e.g. haproxy). Investigation will continue for these. Netflix's testing showed no functional regression and a rather small, albeit statistically significant, increase in CPU consumption with OpenSSL 3.0. Thanks to ngie@ and des@ for updating base system components, to antoine@ and bofh@ for ports exp-runs and port fixes/workarounds, and to Netflix and everyone who tested prior to commit or contributed to this update in other ways.

=head1 NAME
|
|
|
|
SSL_CTX_ctrl, SSL_CTX_callback_ctrl, SSL_ctrl, SSL_callback_ctrl - internal handling functions for SSL_CTX and SSL objects
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
long SSL_CTX_ctrl(SSL_CTX *ctx, int cmd, long larg, void *parg);
|
|
long SSL_CTX_callback_ctrl(SSL_CTX *, int cmd, void (*fp)());
|
|
|
|
long SSL_ctrl(SSL *ssl, int cmd, long larg, void *parg);
|
|
long SSL_callback_ctrl(SSL *, int cmd, void (*fp)());
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The SSL_*_ctrl() family of functions is used to manipulate settings of
|
|
the SSL_CTX and SSL objects. Depending on the command B<cmd> the arguments
|
|
B<larg>, B<parg>, or B<fp> are evaluated. These functions should never
|
|
be called directly. All functionalities needed are made available via
|
|
other functions or macros.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
The return values of the SSL*_ctrl() functions depend on the command
|
|
supplied via the B<cmd> parameter.
