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_state_string, SSL_state_string_long - get textual description of state of an SSL object
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
const char *SSL_state_string(const SSL *ssl);
|
|
const char *SSL_state_string_long(const SSL *ssl);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_state_string() returns an abbreviated string indicating the current state
|
|
of the SSL object B<ssl>. The returned NUL-terminated string contains 6 or fewer characters.
|
|
|
|
SSL_state_string_long() returns a descriptive string indicating the current state of
|
|
the SSL object B<ssl>.
|
|
|
|
=head1 NOTES
|
|
|
|
During its use, an SSL objects passes several states. The state is internally
|
|
maintained. Querying the state information is not very informative before
|
|
or when a connection has been established. It however can be of significant
|
|
interest during the handshake.
|
|
|
|
When using nonblocking sockets, the function call performing the handshake
|
|
may return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE condition,
|
|
so that SSL_state_string[_long]() may be called.
|
|
|
|
For both blocking or nonblocking sockets, the details state information
|
|
can be used within the info_callback function set with the
|
|
SSL_set_info_callback() call.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
Detailed description of possible states to be included later.
