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.

MODIFYING OPENSSL SOURCE
|
|
========================
|
|
|
|
This document describes the way to add custom modifications to OpenSSL sources.
|
|
|
|
If you are adding new public functions to the custom library build, you need to
|
|
either add a prototype in one of the existing OpenSSL header files;
|
|
or provide a new header file and edit
|
|
[Configurations/unix-Makefile.tmpl](Configurations/unix-Makefile.tmpl)
|
|
to pick up that file.
|
|
|
|
After that perform the following steps:
|
|
|
|
./Configure -Werror --strict-warnings [your-options]
|
|
make update
|
|
make
|
|
make test
|
|
|
|
`make update` ensures that your functions declarations are added to
|
|
`util/libcrypto.num` or `util/libssl.num`.
|
|
If you plan to submit the changes you made to OpenSSL
|
|
(see [CONTRIBUTING.md](CONTRIBUTING.md)), it's worth running:
|
|
|
|
make doc-nits
|
|
|
|
after running `make update` to ensure that documentation has correct format.
|
|
|
|
`make update` also generates files related to OIDs (in the `crypto/objects/`
|
|
folder) and errors.
|
|
If a merge error occurs in one of these generated files then the
|
|
generated files need to be removed and regenerated using `make update`.
|
|
To aid in this process the generated files can be committed separately
|
|
so they can be removed easily.
