erlang: Fail to build against OpenSSL 3.0

[Simon Chopin]

Hello,

As part of a rebuild against OpenSSL3, this package failed to build on one or
several architectures. You can find the details of the rebuild at

https://people.canonical.com/~schopin/rebuilds/openssl-3.0.0-impish.html

or for the amd64 failed build, directly at

https://launchpad.net/~schopin/+archive/ubuntu/openssl-3.0.0/+build/22098418/+files/buildlog_ubuntu-impish-amd64.erlang_1%3A23.2.6+dfsg-1.0~ssl3ppa1.1_BUILDING.txt.gz

We're planning to transition to OpenSSL 3.0 for the 22.04 release, and consider
this issue as blocking for this transition.

You can find general migration informations at
https://www.openssl.org/docs/manmaster/man7/migration_guide.html
For your tests, you can build against libssl-dev as found in the PPA
schopin/openssl-3.0.0

Looking upstream, I've found this issue

https://github.com/erlang/otp/issues/4577

However, I don't know what the timeline is for OTP-25 ?

Looking at the logs, it seems the build fails because of FIPS_mode(), which has been removed.
See the migration docs for more info.

Here's a debdiff to enable OpenSSL support for the current 24.1 version, backporting an upstream patchset.

Note that the 24.2, which includes these patches, is scheduled for a mid-december release.

[Simon Chopin (schopin)]

Refreshed the patch against the newer version.

Sponsored to jammy.
