OpenSSL's ENGINE API is deprecated in OpenSSL v3.0.
Use OPENSSL_NO_ENGINE to disallow its use and fall back on the BIO API.

I ran into these same -Wdeprecated-declarations compiler warnings on another
project that uses the ENGINE API to access OpenSSL's support for PKCS#11 tokens.
The conclusion was that in OpenSSL 3.0, the new API for PKCS#11 support isn't
actually ready yet, so we had to keep using the ENGINE API and just add
-Wno-deprecated-declarations to the compiler flags.
Your patch just removes support for PKCS#11 in that case, which seems
undesirable. (Unless no one is actually using it?)

The patch removes support when OPENSSL_NO_ENGINE is defined, but
that's not defined by default in OpenSSL 3.0. (Unless something
changed recently.)
When OPENSSL_NO_ENGINE is defined, ENGINE support is not compiled into
OpenSSL and the headers don't include the functions:
https://github.com/openssl/openssl/blob/master/include/openssl/engine.h
.

Okay so this patch is actually a build fix for when OpenSSL doesn't include
ENGINE support? Currently this patch claims that it's removing the use of a
"deprecated" API, which is something entirely different.

Correct.

The ENGINE API is deprecated in OpenSSL 3.0 but that change doesn't
remove support unless it has already been compiled out of OpenSSL
first.

I see your point.
Happy to rejig the commit message if that would help.

Hi,
These warnings are quite noisy on Fedora rawhide and other distros that
have moved to OpenSSL 3.0. It's not clear to me from this thread if this
patch is actually the correct fix?

I believe it is the correct fix.
However the commit message seemed to cause Eric some confusion.
Would you like me to resubmit?
It would be nice to get some input from the maintainers at one point.

David, do you have an opinion on this? I'd like to see this fixed so
that rawhide builds stop spewing warnings.
Thanks!

OpenSSL's ENGINE API is deprecated in OpenSSL v3.0.
Use OPENSSL_NO_ENGINE to ensure the ENGINE API is only used if it is
present. This will safeguard against compile errors when using SSL
implementations which lack support for this deprecated API.

The `display_openssl_errors` function should probably just call
ERR_print_errors_fp:
https://www.openssl.org/docs/man1.0.2/man3/ERR_print_errors_fp.html
The `drain_openssl_errors` function should probably just call
ERR_clear_error:
https://www.openssl.org/docs/man3.0/man3/ERR_clear_error.html

Did this patch help?
We've had a few confirmed reports now.
My guess is the maintainers are not currently monitoring.
With some more {Reviewed,Tested}-bys I'd be prepared to submit this
via other means. Either via my own repository or via Greg's.
