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.

|
|
|
|
OPENSSL_FILE, OPENSSL_LINE, OPENSSL_FUNC,
|
|
OPENSSL_MSTR, OPENSSL_MSTR_HELPER
|
|
- generic C programming utility macros
|

|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/macros.h>
|
|
|
|
#define OPENSSL_FILE /* typically: __FILE__ */
|
|
#define OPENSSL_LINE /* typically: __LINE__ */
|
|
#define OPENSSL_FUNC /* typically: __func__ */
|
|
|
|
#define OPENSSL_MSTR_HELPER(x) #x
|
|
#define OPENSSL_MSTR(x) OPENSSL_MSTR_HELPER(x)
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The macros B<OPENSSL_FILE> and B<OPENSSL_LINE>
|
|
typically yield the current filename and line number during C compilation.
|
|
When B<OPENSSL_NO_FILENAMES> is defined they yield B<""> and B<0>, respectively.
|
|
|
|
The macro B<OPENSSL_FUNC> attempts to yield the name of the C function
|
|
currently being compiled, as far as language and compiler versions allow.
|
|
Otherwise, it yields "(unknown function)".
|
|
|
|
The macro B<OPENSSL_MSTR> yields the expansion of the macro given as argument,
|
|
which is useful for concatenation with string constants.
|
|
The macro B<OPENSSL_MSTR_HELPER> is an auxiliary macro for this purpose.
|
