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.

Deprecated in OpenSSL 3.0:
|
|
|
|
const char *ERR_func_error_string(unsigned long e);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
ERR_error_string() generates a human-readable string representing the
|
|
error code I<e>, and places it at I<buf>. I<buf> must be at least 256
|
|
bytes long. If I<buf> is B<NULL>, the error string is placed in a
|
|
static buffer.
|
|
Note that this function is not thread-safe and does no checks on the size
|
|
of the buffer; use ERR_error_string_n() instead.
|
|
|
|
ERR_error_string_n() is a variant of ERR_error_string() that writes
|
|
at most I<len> characters (including the terminating 0)
|
|
and truncates the string if necessary.
|
|
For ERR_error_string_n(), I<buf> may not be B<NULL>.
|
|
|
|
The string will have the following format:
|
|
|
|
error:[error code]:[library name]::[reason string]
|
|
|
|
I<error code> is an 8 digit hexadecimal number, I<library name> and
|
|
I<reason string> are ASCII text.
|
|
|
|
ERR_lib_error_string() and ERR_reason_error_string() return the library
|
|
name and reason string respectively.
|
|
|
|
If there is no text string registered for the given error code,
|
|
the error string will contain the numeric code.
|
|
|
|
L<ERR_print_errors(3)> can be used to print
|
|
all error codes currently in the queue.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
ERR_error_string() returns a pointer to a static buffer containing the
|
|
string if I<buf> B<== NULL>, I<buf> otherwise.
|
|
|
|
ERR_lib_error_string() and ERR_reason_error_string() return the strings,
|
|
and B<NULL> if none is registered for the error code.
|
|
|
|
ERR_func_error_string() returns NULL.
